Umbrella- this is a mechanical device, which is a metal or plastic frame made of knitting needles on a tubular rod equipped with a handle, on which a synthetic waterproof material is stretched. An umbrella is designed to protect a person from sunlight and rain.

The umbrella was invented in China 300 centuries ago for protection from the sun. In those days, an umbrella was considered a symbol of power, and only the emperor and those close to him were allowed to use it.

Much time has passed since then, and now the umbrella has become a constant companion for any person in Everyday life. Air design umbrella allows you to make it foldable and light, but unstable to strong gusts of wind. Therefore, over time, everyone is faced with the breakdown of an umbrella, after which many simply throw them away.

But in vain, because you can save money and time, since usually umbrella breakdowns are simple and are associated with a rivet falling out or one of the spokes breaking. Therefore, you can repair an umbrella with your own hands using standard tools and available materials in half an hour.

Repair of the articulated connection of the spokes with the umbrella rods

The most common breakdown of an umbrella is the fall of a tubular rivet from the hinged connection of the rods and spokes. Due to mechanical load in the wind, the edges of the rivet unbend, it falls out and is lost.

Repair using installation as a rivet
paper clip

If the breakdown of the umbrella consists of a tubular rivet falling out of the hinge, and there are no conditions for repair, then it can be repaired using a paper clip.

To do this, just pass the bent end of the paper clip through the holes of the knitting needle and rod, then bend the end of the paper clip, as shown in the photo.

If you have pliers with a wire cutter function on hand, you can take a piece of wire from a paper clip, bend it into a loop on one side, insert it into the holes and form a loop on the other side. Thus, the wire will reliably perform the function of a rivet and will not tear the fabric of the umbrella dome.

Repair using a homemade rivet
copper wire

This is the most reliable way repair that I use in Lately. The repaired hinge joint in the umbrella did not have to be repaired again.

The material used for the rivet is copper wire for electrical wiring with a diameter of about 1 mm. The wire is selected depending on the diameter of the holes in the rod and the spoke.

Before making a rivet, you need to thread the wire through the hole in the rod and check that it moves easily. If it is tight, then you need to slightly reduce the diameter using sandpaper.

Next you need to form the head of the rivet. To do this, the wire is clamped in a vice and the edges are riveted by hitting them with a small hammer, as shown in the photo. If the end of the wire is not flat, then it needs to be processed with a finely cut file.

When repairing an automatic umbrella, to be able to install a rivet, it must be kept in a half-opened position, which is not allowed by the spring, which tends to open the dome. In this case, you need to use a rope to tie the movable lower frame of the umbrella to the handle, as shown in the photo.

On next step you need to insert the knitting needle into the slot of the rod and insert the prepared wire with the head. Cut off the excess wire with side cutters so that the protruding part is about a millimeter.

In the last step, you need to press the created wire head against an anvil (any solid metal object will do) and, with light blows along the edges, flatten the wire until a head is formed. Here is the umbrella hinge that has been repaired.

As practice has shown, although an umbrella is used in wet weather, the copper rivet does not oxidize. If desired, it can be coated, for example, with manicure varnish.

Instead of copper wire Posting nails of the required diameter can be successfully used. Nails are made from soft types of iron and therefore also rivet well.

Repairing an umbrella hinge using a screw connection

You can repair the hinge joint of the umbrella frame using a screw and a nut with a diameter of 1-2 mm of a suitable length.

To do this, you need to align the holes of the parts coaxially, thread a screw through them and screw the nut onto it. If the screw is excessively long, then after screwing the nut, it is necessary to remove the protruding part using side cutters.

Usually, when a screw is bitten, the thread is deformed and the screw will not be able to unscrew on its own. But to be safe, it is better to rest the head of the screw against the anvil and rivet its protruding part from the nut using a hammer.

If there is only a screw and no nut, then you need to shorten its threaded part to the required length and slightly rivet the protruding part.

If at least one rivet has fallen out of the hinge, then others have probably become loose as well. Therefore, in order not to have to repair the umbrella again in the near future, you need to tap all the remaining rivets with a hammer, resting on the anvil.

Repair of spokes and umbrella rods

The second most common reason for umbrella failure is the failure of fiberglass spokes or eyelets on the rods.

Repairing a broken spoke tip

In this umbrella, the end of the tip of the spoke broke off where the hole for attaching the canopy fabric passed through. Most likely from the umbrella hitting a hard surface.

The photo on the left shows a whole tip, and the one on the right shows a broken tip. If you have a new knitting needle or tip, the easiest way is to replace it. But there was no spare spoke available, so it had to be repaired.

To make repairs, a hole with a diameter of about 1 mm was drilled in the tip and the sharp edges where it broke were ground off using a file. To avoid chafing of the thread at the points where it exits the hole, it is necessary to remove the chamfers using a larger diameter drill or a knife blade.

Repairing an umbrella with a broken fiberglass spoke

As a rule, the spokes and rods in umbrellas are made of metal, but recently umbrellas with plastic rods and fiberglass spokes have begun to appear.

The repair was just such an umbrella, in which one of the spokes broke off at the point where the hinge entered the rocker arm. The rest of the spoke remained inside the joint.

In the rocker, the spoke is secured with the help of its curved edges. To remove the rest of the knitting needle, you need to slightly bend the petals to the sides using a thin blade of a flat-head screwdriver.

The broken end of the spoke was a little fluffy, so before fixing it in the rocker arm, it was lubricated with quick-drying waterproof Moment glue.

After compressing the spokes with the petals in the rocker arm, the umbrella began to look like new. The same technology is used to carry out repairs in the event of a broken knitting needle at the tip.

After the repair, the spoke became a little shorter, but visually with the umbrella dome open it was not noticeable.

If a fiberglass spoke is broken in the middle, then its integrity can be restored using a piece of thin-walled metal tube taken from the telescopic antenna of an old radio. The broken ends of the knitting needle are smeared with glue and inserted into the tube so that the joint is in the middle of the tube.

Rod eye repair

If an eye in the rod breaks off, it seems that the umbrella cannot be repaired without replacing the entire rod. But that's not true. Using a metal knitting needle from an old umbrella, you can successfully restore the eye.

The photo on the left shows a working hinge joint, and on the right with a broken eye on the rod.

To repair, you need to take a metal knitting needle about ten centimeters long with a hole at the end from an old umbrella and tin it with solder along its entire length using an electric soldering iron.

Next, you need to remove the rivet from the rod and cover the inner surface of the rod groove with solder, as shown in the photo. When working with a soldering iron, it is necessary to prevent contact of heated parts and its tip with the fabric of the umbrella dome, since the synthetic material may melt.

The next step is to place a knitting needle in the rod groove and heat it along its entire length with a soldering iron until the solder melts both on the knitting needle and in the rod groove. At the same time, you must remember to correctly orient the hole on the knitting needle. Using this technology, you can successfully repair broken rods in the middle.

After installing the rivets using one of the technologies described above, the umbrella repair can be considered complete.

Repair of decorative umbrella cap

It is rare, but it happens that the decorative cap installed on the top of the umbrella dome breaks off or unscrews and is lost.

A cap that has broken off from the threaded part, if present, can be easily repaired by restoring its integrity.

To do this, you need to drill a hole in the center in the threaded part of the cap remaining in the umbrella cane with a diameter equal to the internal diameter of the screw thread.

In the center of the cap, you also need to drill a hole with a diameter equal to the external thread of the self-tapping screw. Thread a self-tapping screw through the cap and lubricate it so that it does not unscrew with any waterproof glue and screw it into the umbrella.

The photograph shows an assembled umbrella repaired with your own hands using the technology described above. The dome fabric is now securely fixed and water will not get on the frame parts.

If the cap is unscrewed and lost, you can restore it using a self-tapping screw with a large press washer.

To do this, you need to make a cork from wood. The diameter of a shortened furniture dowel may be suitable, as shown in the photo.

In the next step, a hole with a diameter equal to the internal diameter of the self-tapping screw is drilled in the center of the plug.

All that remains is to lubricate the thread of the self-tapping screw with waterproof glue and screw it into the plug. As you can see, it turned out beautifully.

If you don’t have a self-tapping screw with a wide head, you can use one from a sheet of plastic suitable color cut a round washer and attach it to the dome. The washer can be made from any cork from plastic bottle by removing the threaded part.

About the repair of automatic umbrellas

Repair of automatic umbrellas is not considered in the article, since it is very labor-intensive and is beyond the capabilities of a home craftsman without repair experience. It is necessary to completely disconnect the dome material from the metal structure, remove the top cage, get to the roller and replace the tape. Required during assembly special device, to compress a fairly powerful spring. Therefore, if the opening mechanism in an automatic umbrella fails, it is better to contact a workshop or buy a new umbrella, leaving the broken one for spare parts.

Hi, I have two umbrellas and they are both broken...they are pretty cheap umbrellas. And the malfunction that happened with the umbrellas is the same. If you're out on a windy day and a gust of wind blows on the inside of your umbrella... those spokes tend to bend or even break. This is exactly what happened with both umbrellas. (Remove the damaged spokes from this umbrella)
Okay, I have various tools collected, but I don't know what tools I will need. We start working with the first umbrella... the one... which is less damaged. You need to choose the best umbrella according to your condition. Why did I decide this? I see only one broken knitting needle here, and one slightly bent one. So I want to leave it as it is and try to restore as much of the umbrella as possible... specifically this spoke and one of the other spokes here.
Do not open an umbrella in the house, this Bad sign. This needle simply came off, since they are mainly sewn to the fabric, which makes them unstable... But you can simply sew it back. Be very careful when repairing your umbrella, as the spokes can easily injure your eyes. This spoke is completely broken. I'll try to remove it and install another one. The most difficult thing is probably to get inside here, because it is very narrow. All the knitting needles are secured with wire, it is wound somewhere here. You'll see a twist here somewhere. I use long nose pliers to loosen the twist. Using pliers, holding the umbrella in your hands, unwind the twist. I'm a little worried the wire will break...wouldn't want to find another piece of wire to replace. But in reality it is not difficult to do, you just need to do it carefully. Okay, you see - we unhooked it, and now I can pull out the knitting needles. We take out all the knitting needles from these grooves in a circle. At the same time, it's worth checking this hub for attaching the spokes... and undoubtedly one of the grooves is broken. This damage is caused by twisting of the wire. The wire is a little bent, so it's a little awkward to remove the knitting needles from it, so I'll straighten it a little with pliers... and pull all the knitting needles off. We disconnected the spoke that broke. The most complicated matter, I think will get to the bottom. When I pressed the sleeve, the umbrella opened. So if I press the wire bandage, the umbrella should open. The design of the wire band at the bottom is exactly the same as at the top - it is a loop made of stainless steel wire. It passes through the holes in the ends of the spokes. You need to get to this wire and unwind it. It's a little awkward... hmm... I'm holding on to the plastic sleeve. Now I can move it a little... Let's check which way the wire is twisted, I think I need to twist it clockwise. Untwisted, and now I can disconnect the spokes. We remove all the knitting needles one by one. This way we will get to the damaged one. (Next we take a knitting needle from another umbrella to carry out repairs)
The damaged knitting needle has been removed, and now I'm going to do the same with the second umbrella to get some good whole knitting needles and put everything back together... In the same way, we unwind the wire of the knitting needle band at the bottom. And like I said, the fabric of the umbrella canvas should be sewn with small loops that give the fabric a little movement, the fastening should not be rigid... so I just cut these loops... and there is another loop here at the joint. .. ... we cut it off too... and at the very end... the fabric here... is sewn incorrectly. The knitting needle is inserted into a hole in the fabric and then sewn on.
There's a flat hole at the end of the knitting needle here. And here is a hole for sewing on this hinge. And there is one more thing where the fabric needs to be sewn. Before installation, you need to check that the spoke is straight and not bent.... it has quite a lot of hinges, part of the spoke moves along this groove. Squeeze the spokes several times to check the operation of the hinges... In any case, the metal of the spokes must be free of rust and damage, because it is the spokes that bear the main load... I will insert the spokes one by one, you need to make sure that the ends of the spokes fit into correct position. Tighten the tip if necessary... the knitting needles should be positioned so that the wire bandage can be tightened... Make sure there is enough space around.
I'll try to use the same piece of wire that was there... that's it. There is a small groove in the sleeve into which the wire should fit. Make sure everything fits correctly before we move on. This can be quite inconvenient. And then I slide the wire into the groove... let me show you this groove... I move the spokes back, and then I twist the wire back the way it was, pull it tight and make sure that the wire lies in the groove like I said. As I said before, the wire should fit into the groove in the plastic sleeve, you can see where the wire should go. You will need to do the same on the middle bushing. Okay, let's try this... it's a little awkward, you have to be careful not to break the other knitting needles while you're trying to tighten the wire. And you will need another spoke, even though you have not yet repaired the previous spoke. Do not tighten the wire too much, make sure that all the spokes are in their grooves and do not pop out, the wire is in the groove of the plastic sleeve. It is here, I don’t know how well it can be seen in the video. There is a small recess for twisting. Now I'll try to show it to you, if possible...
This twist recess is necessary for normal assembly. Because if the twist is not hidden in the groove, then it can turn and tear the material of the umbrella fabric. And a small tear can easily spread. Remember that the wind can be so strong that it can sink ocean-going ships... That's how strong it is. I think it's ok... just pinch and twist the wire and then try to bend the twist into the groove like I was talking about. Watch your fingers because the end of the wire will probably be sharp, I crimped it with the tip of the pliers. I will thread the twist by pressing one end of the pliers on one side of the sleeve and using the other end to thread the twist. Yes, I'm happy with how it turned out. This wire is twisted, the twist is in the extra groove, it sticks out a little, but I'm going to leave it as is. We check that the spokes are correctly laid and inserted... On the top hub I will do the same.... The work is no different, except that it is much easier to get here. You need to check that you keep the knitting needles in the same order, that they are inserted at the bottom and are not mixed up. So, we begin to insert the wire with the spokes into the groove of the sleeve. So far everything is going great... ... I'm inserting these ends of the spokes into the groove one by one... ... this may be a little difficult... we assemble the spokes in a circle one by one and check that all the spokes are in the grooves and the wire is in the groove lies straight. But here on this side the wire is quite sharp, I’ll try to twist it. I try to twist the wire so that both ends are almost touching and the twist fits into the groove. Now I’ll put that knitting needle here. Well, it worked out. They will probably move freely until everything is completely curled. The spoke must be threaded into the groove one way or another... check that the wire goes through both holes in the end of the spoke... ..., make sure that the other spokes have not jumped out of the grooves. Twist the wire together and tuck it into the plastic groove. Twisting may be awkward. This is also due to the fact that the wire is a little uneven... Well, we replaced the knitting needles and sewed on the fabric. Those knitting needles that we took from another umbrella fit almost perfectly. In general, if you buy these cheap umbrellas, you need to understand that they are made by one or two companies in the world. I used to repair umbrellas more often, but now it doesn't always make sense. But everything worked out for us and it seems good. Don't open your umbrella in the house because you might break something in the house or hit someone in the eye. Best wishes.

Answer:

Repair of the machine umbrella device

During the rainy season, the most relevant accessory is, of course, an umbrella. But everyone knows the eternal problem of even the most expensive umbrellas: they break easily, and even a strong gust of wind can damage them. The biggest nuisance is if the automatic umbrella, although simple, is still a mechanism, breaks down.

Knowing the repair is much easier:

1. Actually a pen, with a button built into it.
2. Three extendable iron tubes.
3. The lower support for the spokes, in which there is a wheel for the cord and a thin rail that attaches the support to the handle.
4. The upper support for the spokes, into which a wide pipe is mounted using a screw and a cord is attached to it.
5. Plastic pipe. It is inserted into the upper support. In the upper part it has a thickening and a wheel.
6. Cord. Using a shuttle, it is attached to the handle, and a button releases it.

The weakest point of an umbrella is its spokes. If the problem is with them, then you need to take a thin tube three centimeters long, and then straighten the broken knitting needle at the ends, put the tube on them and secure it. Take a metal tube.

If the rivet at the end of the knitting needle is broken, it is better to wrap it with soft wire, otherwise the fabric of the umbrella will tear.

Repairing the machine's umbrella device is very labor-intensive; for example, if the tape breaks, it needs to be replaced. We remove the plug that is located on the top, then the fabric, and pull out the fixing nail from the knot. Then we take out the entire assembly and carefully open the tube. Do this carefully, otherwise the spring will pop out and then cannot be inserted. We take out the roller, change the tape, and assemble everything in the reverse order.

If the rod is broken, it needs to be repaired only after you have loosened all the connections and removed them from the hooks. The repair process is not easy and you need a soldering iron to repair the machine's umbrella device. So, we take tinned tin and make a trough out of it, approximately 40x12 millimeters in size. It needs to be installed in place of the damage and soldered along its entire length.

A broken latch is repaired as follows: press on the protrusion that blocks the mechanism and move it towards the handle. We take it out of the tube, straighten it and mount it back.

Often the product does not allow you to repair the device of the machine umbrella, since a diagram is needed. But if you managed to get it (and this is not a problem in the information age), then you will succeed, because the process, although long, is not particularly difficult. In general, if you handle your umbrella carefully, you won’t have to repair it.

And you can also look video Repairing a semi-automatic umbrella with your own hands

An umbrella serves as an indispensable accessory in rainy weather, protecting against the flow of water and wind. If after another bad weather it has lost its attractiveness or one of its main parts has broken, do not despair and do not rush to throw it away. It can always be fixed! Before repairing an umbrella, study its structure and determine whether it is possible to repair the faulty spare part. Sometimes automatic designs may require the help of a specialist.

Types of umbrellas

There are varieties of designs and differences between folding mechanisms from each other. The most important part of any umbrella is the dome, consisting of a metal frame or plastic spokes, on which fabric is stretched and a solid or folding handle. Each model can be equipped with a simple or automatic mechanism. All umbrellas are conventionally divided into:

• canes– have an enlarged dome made of thick fabric, a strong handle;
• folding– the structures have a telescopic device and can be folded and reduced in size (from two to five times).

Depending on the opening mechanism, there is a division into the following types:

• mechanical– open and close by hand, there are no buttons on the handle;
• semi-automatic– open manually, the automatic mechanism closes the dome when you press the button, and the handle shaft folds by hand;
• automatic– the button opens the dome, but you need to close it with your hand;
• full automatic– a button is used to open and close; no effort is required.

Device

IN different models designs vary, but there are basic parts for all umbrellas. Main elements:

• fabric stretched over a frame;
• a rod consisting of telescopic parts of a tube;
• handle, with or without button;
• lower spoke supports;
• upper supports to which the main dome is attached;
• springs (thick short and thin long);
• A wheel is built into the upper part of the plastic tube (holder) that secures the lower supports.

The most common malfunction is when automatic umbrellas lose their rigidity. This happens when the wind turns them inside out, bending the thin knitting needles. It is important to periodically check the joints of the spokes and, if necessary, strengthen the weakened tissue. The same rule applies to all umbrellas: the fewer connections there are on the rod and spokes, the less often the structure breaks.

Spare parts

No matter how expensive and high-quality an umbrella is, it cannot be insured against breakage. Before throwing away your old one and buying a new one, try repairing your umbrella. If you have a second - unnecessary copy - then it can become a source of scrap materials for restoration. Urgent repairs of umbrellas, if necessary, can be performed by professional craftsmen in specialized modern institutions such as the House of Public Services.

The following components are subject to replacement and repair:

• telescopic the shaft or base of a cane;
• knitting needles from different material;
• pen any configuration;
• dome material;
• safety spoke tips;
• center cap;
• buttons.

DIY umbrella repair

Depending on the cause of the malfunction, prepare necessary materials and auxiliary tools. This could be a finished part from an old umbrella, pliers, wire or a tool for soldering metal parts. At home, you can repair the automatic umbrella with your own hands and eliminate the following breakdowns:

• damaged fabric at the seam;
• the tip of a knitting needle has fallen off;
• bent and broken knitting needles;
• faulty latch.

Fabric repair

To connect the seam on the dome, select threads of the appropriate color: you should carefully sew the fabric by hand. If the material comes off the end of the knitting needle, then use a thin fishing line to wrap the edge and secure it with a knot. Thread the ends of the fishing line into the hole of the knitting needle and secure it with several knots. This procedure performed with the tissue freely positioned on the frame.

Spoke repair

How to repair an umbrella if the spokes are damaged? Follow step by step instructions:

• First, you should detach the fabric from the frame of the product, remembering the location of the material.
• Next, you need to straighten the damaged knitting needles. If a part is unusable, it must be replaced. Use a soldering iron to fasten or secure the metal parts of the knitting needle with wire (you can use a piece of paper clip).
• Upon completion of work, secure the material with fishing line to the frame.

Holder repair

If the umbrella does not stay open, try to repair the product yourself. This kind of damage can be easily fixed if the latch is bent. To do this, press on the protrusion and sharply move the part to the side. This way the latch tongue is pulled out and carefully straightened. Install it back in the same way. Please note: if the spare parts for umbrellas are of poor quality, then such repairs will not last long. In this case, you just need to replace the damaged part. You can take it out of an old umbrella and insert it into the handle.

Automatic umbrella repair

Repairing an automatic umbrella is a little more difficult than a mechanical one, and it takes more time. Sometimes the breakdown is associated with improper use of the product, then the parts are severely deformed and can only be replaced with new ones. If the machine itself is faulty, it is better to contact specialists in specialized institutions where umbrellas are repaired. This process is performed in short time.

Where to repair an umbrella

Repair of damaged products of any complexity is carried out by specialized workshops or stores that provide repairs to shoes and clothing. In large cities such as Moscow and St. Petersburg, there are service centers that provide high-quality repairs of umbrellas. In small towns there are also centers where the service will cost even less. Pay attention to advertisements on the Internet, in newspapers, read reviews, customer recommendations, compare prices.

Minor damage to the umbrella and throw it away? It turns out that faulty umbrellas can be fixed at home using A. Mokrov’s technology.

Rod repair

The main failure is the place of their hinge connection, carried out using an axle. Most often this happens in node b(Fig. 1) with high traction, which carries the main load when the umbrella is open. Even a slight lateral pressure on this rod leads to breakage, as a result of which the compression hook of the power spring is lost.

Rice. 1. Umbrella frame design: b,c,d - locations of the most common breakdowns; 1 - upper rod attachment; 2 - hairpin; 3 - shock absorption spring; 4 - power spring bushing; 5 - power spring; 6 - sleeve for fixing the umbrella when folded; 7 - cavity for the latch hook; 8 - power spring compression hook; 9 - traction

The easiest way to repair broken rods is if you have intact rods from some other umbrella of a similar design that cannot be repaired. To separate the required rod from the umbrella frame, it is enough to cut off the flaring of the axles on a suitable rod with a knife and disconnect it from other rods and assemblies. The axles for the rod can be made from wire of the required diameter and the ends of the axle can be soldered to the sides of the rod.

If you don’t find a suitable rod, then they make more complex repairs. First of all, when starting to repair the rod, you should relieve the tension in the elements of the umbrella frame created by the power spring.

To do this, the upper end of the umbrella is rested against some surface and the power spring is compressed using the sleeve for fixing the umbrella when folded so that all the hooks that hold the spring in a compressed state can be freely unhooked from the rods. When releasing the hooks, you must not weaken the compression of the spring, otherwise the other rods may break.

A broken rod can be repaired using a connecting pad. First, a plate measuring 45x13 mm is cut out of 0.2-0.3 mm tinned sheet metal (the width is given in excess, since it is not always possible to bend the plate symmetrically exactly along the longitudinal axis), and then the plate is turned into a “trough” - they are attached to the lining the required form, which should fit tightly onto the rod being repaired (Fig. 2a).

The broken and attached (whole) rods are freed from the fabric. If a broken rod is deformed, it is straightened. The areas of the connected ends of the rod, which will be located under the lining, are tinned. If the axle on the attached (whole) rod has no defects, the rod with the axle is installed in place (Fig. 2b).

Rice. 2. Repair of broken rods (using a pad): a - overlay; b,c,d - sequence of operations during repair; d - repair with installation of a new axle. 1 - whole thrust; 2 - broken rod; 3 - overlay

The axle on both sides is secured to the rod by soldering and a connecting plate is installed (Fig. 2c). Having fixed the end of the rod and the pad in the desired position using a compression clamp, the pad is soldered to the rod without disturbing the soldering of the axle. The other half of the rod is firmly inserted into the overlay (Fig. 2d), after which the rod is fixed and the overlay is soldered along its entire length. Finally, the joint is brought into proper shape and the functionality of the hinge joint is checked.

If the axle on the attached rod is severely bent or has any other defect, it is removed. In this case, a hole with a diameter of 1.5 mm is drilled in the lining, coinciding with the hole on the rod being repaired. A wire is inserted into the hole, which will act as an axis.

Next, carry out the same operations to connect the rods. The wire is taken out and an axis of the required length is made from it and the rod axis is connected. To prevent the axle from falling out of the rods and catching the fabric, it is soldered to the pad on both sides (Fig. 2d).

The attachment of the fabric to the rods is restored. If there is easy access to the soldering point of the rod, it is better not to disconnect the fabric from the frame, but in order to avoid hot drops of tin getting on the fabric, you must first place a gasket between the fabric and the soldering point. Breaking at node with(Fig. 1) is eliminated in the same way.

Broken rods in nodes b, c, d umbrellas with frame elements made of thicker steel (in this case, the rods have narrower sidewalls) are connected using plug-in ears, which are pressed against the sidewalls of the rods. Most often, breakage of the rods of such umbrellas occurs in node d(Fig. 1), since in this place the strength of the thrust is weakened by the hole intended for the compression hook of the power spring.

To repair such a rod, an insert-eye is bent from strong steel wire, the shape of which is shown in Fig. 3a. Please note that recesses are made on the ear inserts for a more reliable connection with the rods. The wire is selected with such a diameter that the insert fits tightly between the sidewalls of the rod. The length of the entire insert is approximately 45-50 mm. The main requirement for the insert: when installing it in place, the hook hook can move freely in the resulting cavity, and the insert itself does not interfere with the compact folding of the umbrella.

Rice. 3. Repairing broken rods (using a pad): a - insert; b - overlay; c,d,e - sequence of repair operations. 1 - notch; 2 - crimping point

At the point of failure, to enhance the strength of the traction, you still need to make an overlay of tinned sheet metal with a thickness of 0.2-0.3 mm (Fig. 3b). After making the fasteners, the broken rod is straightened. The finished connecting insert is tinned with a thin layer of tin and inserted into the broken end of the rod closest to the handle so that the highest point of the curved part of the insert is located above the end of the hook hook (Fig. 3c).

Then the end of the insert is crimped with the sidewalls of the rod. Next, the second part of the rod is placed at the free end of the insert, the rod is compressed around the insert and the latter is soldered along its entire length. To increase the reliability of the connection, put a cover over the area to be repaired, having previously drilled a hole in it with a diameter of 1.2 mm, coinciding with the hole on the rod being repaired, and solder the cover to the rod.

By opening and folding the umbrella, check the correctness of its repair and assembly. It happens that after repair, umbrellas of this type do not fold completely. One of the reasons for this is the displacement of ear inserts in repaired units (especially in node b, usually resulting from poor-quality crimping of the rods by their sidewalls. To eliminate such a defect, it is necessary to lightly hit the part of the eye protruding from the rod with a small hammer, move the eye to the desired place and again tightly press the insert with the sides of the rod.

Power spring repair

For umbrellas that have an extended power spring in their design, the power spring bushing quite often cracks. Typically, failed bushings cannot be repaired, so to replace them, use suitable bushings from umbrellas of other designs.

The new bushing can be installed through either the top or bottom of the umbrella shaft. You just need to determine which pin is easier to choose: the pin that fixes the handle, or the pin that holds the upper tie rod attachment.

First of all, you need to free the rods from the broken bushing and remove it. Installation of the bushing through the upper part of the rod is carried out in the following sequence: move the shock-absorbing spring down (Fig. 1), knock out the pin from the upper attachment point of the rods, remove this unit and install a new bushing. The umbrella is assembled in the reverse order.

To perform all of the above repairs, it is necessary to remove the power spring compression hooks. Upon completion of the repair, the presence of these hooks is checked, and if necessary, the missing number is made according to the shape of the existing ones.

The umbrella fixing sleeve is installed folded so that the cavity (slot) of the hook on it is in line with the protrusion of the latch. then the hooks are hooked onto the bushing, the power spring is compressed and the hooks are inserted into the rod hole. At the end of the work, check the correctness of the repair and assembly by opening and folding the umbrella.

Retainer repair

Quite often, due to excessive tension in umbrellas with manual opening, the eyelet in which the axis of the clamp is installed breaks in the mechanism that fixes the umbrella when opened (Fig. 4a, the location of the breakage is shown with a dash). Umbrellas with a three-stage rod are especially susceptible to this type of breakdown. If it is not possible to replace a failed mechanism, it can be repaired by making a clamp from tinned sheet metal with a thickness of 0.-0.3 mm. The dimensions of the blank for the clamp depend on the dimensions of the mechanism sleeve.

In Fig. Figure 4b shows the dimensions of the clamp blank for the fixation mechanism when the umbrella is open. The 35 mm dimension is the distance on the workpiece from eye to eye, measured along the outer diameter of the sleeve. The dimensions of clamp blanks for other mechanisms are determined in the same way.

The edges of the workpiece are bent (along the dotted lines). Then they apply the edges to the ears of the mechanism, transfer the contours of the ears to the edges and precisely mark the location of the hole of the latch axis. Excess areas on the bends are removed. To increase the strength of the clamp ears, it is better to solder to them plates cut to size and shape (Fig. 4b(2)), not forgetting to drill holes in the bends.

Next, the workpiece, without allowing distortion, is bent around a tube (rod), the diameter of which corresponds to the diameter of the bushing of the fixation mechanism. After this, they put the clamp in place (that is, on the bushing), eliminate the inaccuracies, select a screw with a nut instead of the axle, and assemble the mechanism. A drawing of the finished clamp is shown in Fig. 4b (3).

Rice. 4. Repair of the retainer: a - mechanism for fixing a hand umbrella when opened: 1 - rod attachment unit, 2 - latch, 3 - eyelet; b - option for repairing the umbrella fixation unit when opened using a clamp: 1 - pattern of a clamp blank, 2 - blank with soldered plates, 3 - drawing of a clamp; c - option for repairing the umbrella fixation unit in an open form using surfacing and half-clamps: 1 - surfacing, 2 - half-clamp; d - latch design: 1 - locking protrusion, 2 - handle tube, 3 - hook protrusion

There is another way to repair this mechanism. It is a little simpler and takes less time to repair, but the ears are less durable. Take a small piece of plywood about 5 mm thick and insert it into the slot of the fixation mechanism between the broken ears. In the plywood along the remaining part of the eye, mark and drill a hole for the axle. insert nails of the appropriate diameter into the hole. Install the plywood on the axle in the slot. From fragments of ears or other suitable material weld (with heated plastic) onto the mechanism body or glue the missing parts of the lugs to it.

Then two strips half the thickness of the ear are cut out of tin (stainless steel, copper, brass) and bent into a half-clamp. By placing one half-clamp on the ear, as shown in Fig. 4c, heat the half-clamp with a soldering iron, gradually pressing it into the ear. The second half-clamp is also pressed into the other ear. They take out the stud-axle, remove the plywood, process the lugs and assemble the mechanism. The quality of welding must be checked for strength.

We must not forget that welding of plastic parts must be performed in a well-ventilated area.

Sometimes the protrusion of the hook at the latch holding the umbrella when folded stops returning to its original position. Most often, such a breakdown occurs in children's umbrellas with automatic opening. This usually happens in cases where the retainer is made of low-quality metal. It simply bends under load.

To eliminate the malfunction, press the locking protrusion (Fig. 4d), move the protrusion towards the handle, pull out the latch from the rod tube, bend the latch at the bend point, and then insert the latch into place, the malfunction is quickly eliminated. But after some time, the retainer will lose its shape again, so it is better to immediately replace it with a retainer made of high-quality steel. If you don’t find one, it’s easy to make a retainer yourself from elastic metal.

Canopy Fabric Repair

The broken ends of the rods tear the fabric of the umbrella. Small holes can be sealed with the same fabric using BF-6 glue. You can also stick a transparent self-adhesive film to the damaged area, which is much simpler. Lightly frayed fabric can be strengthened by smearing the inside with colorless nail polish.

If the fabric of the umbrella comes off the end of the knitting needle, you need to take a thin fishing line, wrap the end of the fabric three times and tie a knot. Then thread the fishing line through the hole at the end of the knitting needle and secure the fabric.
