The more complex the mechanism, the more nodes and elements in it that can fail. The automatic umbrella is no exception in this regard. During long-term operation, repeated opening / closing, the product starts to work incorrectly, and sometimes even becomes unusable.
Button breakage, or rather its jamming, is one of the most frequent problems faced by the owners of automatic umbrellas.
At the same time, many believe that a broken umbrella cannot be repaired, so they buy a new one.
In fact, almost any umbrella (unless, of course, it is a cheap one-time copy for 300 rubles) is repairable. Moreover, in order to fix it, you do not need to go to the workshop - most of the problems can be easily eliminated with your own hands.
Before proceeding with the repair of the button, it will not be superfluous to familiarize yourself with the device and the principle of operation of the automatic umbrella.

Attention! If the problem returns over time, you can completely remove the pusher and use the umbrella as a semi-automatic. However, for this, it is necessary to preliminarily weaken the central spring as much as possible (this is done by cutting off a part of the spring) and removing the springs on the beams.
The umbrella serves as an indispensable accessory in rainy weather, protecting from the currents 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 device, determine whether it is possible to repair a faulty spare part. Sometimes, for automatic constructions, you may need the help of a specialist.
There are varieties of designs and differences between folding mechanisms from each other. The most important part of any umbrella is the canopy, which consists of a metal frame or plastic knitting needles, on which fabric is stretched and a one-piece or foldable handle.Each model can be equipped with a simple or automatic movement. All umbrellas are conventionally divided into:
canes - have an enlarged dome made of dense fabric, a sturdy handle;folding - structures have a telescopic device, can be folded - 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 - they are opened manually, the automatic mechanism closes the dome when the button is pressed, and the handle rod is folded by hand by hand;automatic - the button opens the dome, but you need to close it with the effort of your hand;full automatic - a button is used to open and close, no effort is needed.
The designs differ from model to model, but there are basic details for all umbrellas. Main elements:
fabric stretched over the frame;
a rod consisting of telescopic tube parts;
handle, with or without button;
lower spoke supports;
upper supports, to which the main dome is fixed;
springs (thick short and thin long);
a wheel is built into the upper part of the plastic tube (holder) that fixes the lower supports.
The most common malfunction is when automatic umbrellas lose their rigidity. This happens when the wind turns them inside out, arching the thin spokes. It is important to periodically check the knitting points and, if necessary, reinforce the weakened fabric. For all umbrellas, there is a single rule: the fewer connections on the rod and knitting needles, the less often the structure breaks.
Whatever the expensive and high-quality umbrella, it cannot be insured against breakage. Before you throw your old one away and buy a new one, try to get your umbrella repaired. If you have a second - unnecessary copy - then it can become a source of scrap materials for restoration. Urgent repair of umbrellas, if necessary, can be carried out by professional craftsmen in specialized modern institutions like the House of Life.
The following components are subject to replacement and repair:
telescopic rod or base of a cane ;
knitting needles from various materials;pen any configuration;dome material ;safety needle tips ;
center cap ;buttons .Prepare the required materials and tools, depending on the cause of the malfunction. This can be a finished part from an old umbrella, round nose pliers, wire, or a tool for soldering metal parts. At home, you can repair the automatic umbrella with your own hands, fix the following breakdowns:
damaged tissue at the seam;
flying off the tip of the spoke;
bent and broken knitting needles;
faulty retainer.
To join the seam on the dome, select the threads of the appropriate color: you should carefully, manually, sew the fabric. If the material comes off the end of the knitting needle, then wrap the edge with a thin fishing line and fix it with a knot. Pass the ends of the fishing line into the hole of the knitting needle and fasten it with several knots. This procedure is performed with a free arrangement of tissue on the frame.
How to repair an umbrella if the spokes are damaged? Follow the step by step instructions:
First, you need to 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 the part is unusable, it must be replaced. Use a soldering iron to staple or wire the metal parts of the knitting needle (you can use a piece of paper clip).
Upon completion of the work, secure the material with a fishing line to the frame.
If the umbrella does not hold open, try repairing the product yourself. Such damage is easily repaired if the latch is bent. To do this, press the ledge and sharply move the part to the side. This pulls out the tab of the retainer and gently straightens it. Install it back in the same way. Please note: if the spare parts for the umbrellas are of poor quality, then such repairs will not last long. In this case, you just need to replace the damaged part. It can be taken out of an old umbrella and inserted into the handle.
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 they can only be replaced with new ones. If the machine itself is faulty, it is better to contact the craftsmen in specialized institutions where umbrellas are repaired. This process is carried out in a short time.
Repair of damaged products of any complexity is carried out by specialized workshops or shops, which provide for the repair of shoes and clothes. In large cities, such as Moscow, St. Petersburg, there are service centers that provide high-quality repair of umbrellas. Small towns also have centers where the service will cost even less. Pay attention to advertisements on the Internet, in newspapers, read reviews, customer recommendations, compare prices.
Do-it-yourself machine umbrella repair
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 disable them. The biggest nuisance is if the automatic umbrella broke, albeit a simple, but still, mechanism. Knowing the device of the automatic machine's umbrella, the repair is much easier:
The handle itself, with a button embedded in it. Three expandable iron tubes. Lower spoke support, which contains a cord wheel and a thin rail that attaches the support to the handle. The upper support for the spokes, into which a wide pipe is mounted with a screw and a cord is attached to it. Plastic pipe. It is inserted into the top support. In the upper part it has a thickening and a wheel. Cord. With the help of a shuttle, it is attached to the handle, and a button releases it. The weakest point of the umbrella is the knitting needles. 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 fasten. Take a metal tube.
If the rivet at the end of the spoke breaks, then it is better to wrap it with soft wire, otherwise the fabric of the umbrella will break. It is very time-consuming to repair the machine's umbrella device, for example, if the tape breaks, then it must be replaced.
We remove the plug that is located at the top, then the fabric, and pull the retaining nail out of the knot. Then we take out the whole assembly and carefully open the tube. Do it carefully, otherwise the spring will pop out, which then cannot be inserted.
We take out the video, change the tape, collect everything in the reverse order. If the rod breaks down, then you need to repair it only after you loosen all the connections and remove them from the hooks.
The repair process is not easy and you need a soldering iron to repair the umbrella device. So, we take tinned tin and make a trough out of it, about 40x12 millimeters in size. It must be installed in place of damage and soldered along its entire length.
A broken latch is repaired as follows: press on the protrusion that blocks the mechanism and slide 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 automatic umbrella, since a circuit 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 the umbrella carefully, you won't have to repair it. And also you can see Repair of a semi-automatic umbrella with your own hands
The step-by-step repair of the automatic umbrella with your own hands is shown in. How to repair an automatic umbrella (semi-automatic) with your own hands? The main reason for the breakage of the umbrella ... Video Rating: 4/5
Thanks for the good educational program. I only put rivets and crimps, change the needles, sometimes twist the needles on the crown.And what kind of lace can be used as a "thread" ??
The umbrella opens after applying force to close, but does not fold when the button is pressed. How is the repair done in this case ??
I don’t know how to whom, but thanks for that. If someone does not like the "ideality" of teaching this, then let him either create something similar in the best quality of explanations, or let him stand silently aside. Thanks to him, I figured out how to fix my umbrella. There were jokes - then it would fly out, then it would get stuck there. And the design of my pen is completely different. I looked where I was interested - I did the rest myself. In general, I had a problem - an external metal axis clung to the white button in the handle. The whole whole - had to be finalized - by melting the slot. My umbrella cannot be closed like that - in the open state after pressing the button - this is probably already your wisdom. Mine needs to be pulled to close. In short - for THANKS! Not everything was given, but quite a lot !?
A good umbrella is indispensable during the rainy season, but strong winds or careless handling can damage it. Do not rush to throw away the broken automatic umbrella, it is quite possible to fix it yourself.
- metal tube with a diameter of 6 mm; - tin plate; - finished parts from another umbrella; - soldering iron; - pliers. Instructions: Most often, flute needles break in any umbrella.
To repair them, find a metal tube with a diameter of 6 mm and cut a piece 3 cm long. For this purpose, you can use the antenna from a portable TV or radio.
Straighten the ends of the broken knitting needle, slide on the tubing and squeeze the ends with pliers. If the tubular rivets at the ends of the knitting needles are damaged, insert a small piece of soft stainless wire into the hole and tighten the ends. Not paying attention to this problem, you run the risk of finding damaged umbrella fabric. The design of the automatic umbrella provides for work with a tape, if it breaks, replace it.
To do this, unscrew the top plug, remove the panel, remove the nail-fixer from the top unit. Then remove the entire assembly, place your hand over the open tube and very gently open it. Be careful - there is a powerful spring inside that can fly out.
Take out the roller and replace the tape. Very often, in automatic umbrellas, the rod breaks at the point of their hinge. It is necessary to start repairing the rod only when all connections are loosened and removed from the hooks.
Cut a small 40x12 mm plate from a piece of tinned 0.2-0.3 mm tin and bend it lengthwise, turning it into a trough. If one of the halves of the broken rod is deformed, straighten it.
Tin the ends and install the cover, solder the repair site along the entire length. In children's umbrellas with automatic opening, the lock that holds the mechanism closed sometimes stops working. You can eliminate such a malfunction of the automatic umbrella as follows: press the locking tab and slide it towards the handle.
Pull the bent retainer out of the stem tube and straighten, then reinstall. If the metal is of poor quality, such measures will not help for long, so it is better to replace the retainer with a new one.
Miscellanea. May 29, 2012. Nikolay
It starts to rain, I press the button of the umbrella, it pops up, but the dome does not open. I hold an umbrella with one hand, with the other I open the dome and run to work. The umbrella does not fold completely, then I notice that the cord that opens the dome is dangling, not tied to anything.
I started googling and found a bunch of similar articles on completely different mmm. bad sites. Articles are moronic, like "gavriliad" of 12 chairs.
About repairing anything, from rubber boots to a "gamepad" with the same recommendations: is it worth repairing, and not look for a repair shop and search the internet for repair recommendations (and they have the same nonsense). The creators of such rubbish must understand that their creations are analogous to garbage on the side of roads, broken bottles in forests and along river banks, filthy elevators.
Unfortunately, they make up 90% of the search, but you can identify them by the first words. And now - closer to the body! My umbrella consists of the following parts: - three sliding iron tubes; - the lower spoke support, it has a wheel for the cord and a hook to the handle; - the upper spoke support, the end of the cord is attached to it, the extreme (thick) pipe is inserted into it and fastened a transverse nail; - two springs (thick-short and thin-long); - a plastic tube.
Its upper part is thickened, with a wheel and is inserted into the upper support; - a cord, at one end there is a plastic shuttle that hooks to the handle, and is released with a button. The other end goes through a plastic tube, a wheel in it, through the wheel of the lower support and is attached somewhere in the upper support. Since the end of the cord with a knot jumped out of the wheel on the lower support and got stuck in the upper support, I had to disassemble it.
He opened the dome, put it on the table with the dome down and slightly pressing down with the thick pipe, pulled the nail out of the upper support. Hold tight, disassemble slowly, there are long and strong springs. Memorize or write down what was collected and how.
It is important to remember the rotation of the handle relative to the lower support, because the support goes into the handle and is fixed with a button. I untied the knot at the end of the cord (otherwise it would not go into the wheels), using a thin needle and thread, pulled the cord as described above.
I still don't know how to attach the end of the cord, I just found a similar cord and tied it to the old one. Now the assembly is in the reverse order: - check that the wheel and its axle are "recessed" in the thickening of the plastic tube, otherwise the thick iron pipe will not go beyond the wheel axis; - insert the thickened plastic tube into the upper support, pull the cord so that the shuttle is close to the tube ; - put a thick spring on a plastic pipe, then a thin one.
A thin spring must go through a thick one. It is better to do this with an assistant; - now the most difficult thing is to put the pipes on the spring and, compressing it, insert the thick pipe into the upper support. Orient the cutout in the pipe to the wheel, and the latch on the handle to the bracket in the lower support.
Use the fifth hand 🙂 to secure the iron pipe in the upper support with a nail. Exhalation. I did it alone, but after 24:00: (There is a hole in the upper support on top, to get to it you will have to slightly perforate the fabric in the center of the dome.
Find a suitable screw or self-tapping screw and screw into the hole. Bring the end of the cord to the top of the dome to the screw and tie it temporarily.
Now carefully try to close / open the umbrella and select the length of the cord, then tie it up completely and somehow disguise our "collective farm tuning". This is not a general guide, but a particular case. To paraphrase AN Tolstoy, "All serviceable umbrellas are alike, each broken umbrella is broken in its own way."
Shows the step-by-step repair of the automatic umbrella with your own hands. How to repair an automatic umbrella (semi-automatic) with your own hands? The main reason for the breakdown of the automatic umbrella is the use of force to close the umbrella, as in conventional umbrellas. At the same time, the thread that opens the umbrella breaks or a fragment of the part to which this thread is tied breaks. after that, the umbrella fires, but does not open. Attention! The nylon thread used in is not suitable for repairing an umbrella. It is too thin and ripped almost immediately. After replacing the thread with a stronger one (the thread from the blinds), the umbrella works safely. Subscribe to the HotSEM channel! Find out what's next!
With the onset of autumn, more and more often, leaving the house, we take an umbrella with us. And if we use a reliable cane umbrella, if it is raining or storm clouds appear on the horizon, then the automatic umbrella is in our purse “just in case”.
And this case comes often: an unexpected rain with a gusty wind - and our compact "magic wand" is broken. Prices for repairing umbrellas are considerable, and the workshop is often located at a decent distance from the house.
Is it possible to repair the automatic umbrella with your own hands? Let's figure it out! If the umbrella is cheap, then it's probably better to buy a new one.After all, a repaired flimsy and low-quality mechanism will not last long - it will break again.
However, if the product is expensive, you can try to do it yourself at home. Grooved knitting needles are the most vulnerable part of the umbrella mechanism. In the old days, they were made of steel; now, economical manufacturers use cheap aluminum and plastic.
A knitting needle broken by the wind can be replaced with a similar part from an old Soviet umbrella (do not throw them away, leave them for spare parts). If you cannot pick up a knitting needle, any metal tube 5-6 millimeters thick will do.
Do-it-yourself repair of an automatic umbrella in this case is simple - straighten the needle from the end with pliers, put a tube on it and squeeze it again. The second common cause of breakage is loose rivets. Now they are made thin, of copper or brass, so they often fall out.
If you do not repair the automatic umbrella with your own hands right away, it is better not to use an umbrella at all - a loose knitting needle will easily tear the fabric. It is quite easy to fix this problem - take a small piece of wire and fasten the loose ends together. The simplest breakage is broken or frayed threads.
Take a steel or regular strong thread or fishing line, restore the broken seam. Everyone can do this do-it-yourself automatic umbrella repair. If you notice traces of rust on the fabric from a poor-quality alloy of the umbrella parts, it doesn't matter, they can be easily removed.
Wipe the rusty stain with lemon juice and run it under cold running water. If the umbrella is heavily soiled, ammonia will help, or rather, its solution (half a glass per liter of water). Sometimes, even on high-quality umbrellas, scuffs appear over time - this is also easy to eliminate.
Do-it-yourself umbrella repair here consists in applying transparent nail polish to the scuffs. After that, the umbrella is dried in a half-closed state - the fabric should not be too stretched. If the automatic mechanism itself has become unusable, you will have to carry the umbrella to the workshop. Even if you are well versed in technology and understand how to eliminate this breakdown, you still cannot close the spring of the mechanism - this can only be done with a special device that the craftsmen have.
If the handle or the tip of the umbrella is broken, look at your friends for the same, but old umbrella and ask for a spare part, or just take it to the workshop where a new part will be made for you. or cane umbrellas. Women's umbrellas are capricious and fragile!
The weather is often unpredictable, and small rain can turn into torrential rain with strong gusts of wind. If your automatic umbrella breaks down during such a natural storm, do not rush to carry it to the workshop or throw it away. Our tips will help you repair it at home. By the way, see if you already have broken umbrellas in your house, the details of which you can use during the repair process.
Diagram of the construction of a standard automatic umbrella
The structure of umbrellas can be very different, but in general, several main parts of the structure can be distinguished. The main elements are a handle with a button, sliding tubes (there are 6 or 8 of them in the device), lower and upper supports for the needles, a plastic pipe. The upper part of the latter is thickened, a wheel is attached to it, which is inserted into the upper spoke support. In turn, short and long springs are attached to the support.
This is interesting: The most common today are semi-automatic umbrellas. They open when you press a button, close - manually. In a fully automatic umbrella, pressing a button both opens and closes the umbrella.
There are enough parts in automatic and semi-automatic umbrellas that could theoretically break. But, as practice shows, there are 5 most common breakdowns.We invite you to learn about the methods of eliminating them.
An antenna from an old TV or radio can be useful for repairing a spoke.
As it turns out in practice, it is the grooved knitting needles that break most often. In order to eliminate the malfunction, take a metal tube with a diameter of 6 mm and cut a small piece 3 cm long from it. The tube can be a spoke from another umbrella, an antenna from a receiver or TV. Straighten the broken knitting needle of your umbrella, put the prepared element on top of it and clamp it with pliers on both sides. Then put on the umbrella cover and try to open and close it several times. If the spoke doesn't fall out, you've done everything right. Feel free to continue using your favorite umbrella.
Useful information: Modern models of automatic umbrellas use from 8 to 16 spokes. The more needles a particular model has, the smoother the dome will look: the fabric will not sag. Also, an umbrella with more needles resists the wind better. Even with strong gusts, it will not bend in the opposite direction.
It also happens that the tips themselves break on the knitting needles. Then the fabric material ceases to hold and the spoke is exposed. This can harm both you and those around you, as the needles are sharp enough. They can scratch the body, rip clothing, etc. You will need stainless steel wire for repairs. Thread it into the knitting needle, roll the other edge in the form of a small sphere. Then stretch the fabric and insert it into the resulting ball. The most important thing is to twist the wire tighter so that after repair the spoke does not jump out in a strong gust of wind.
The design of automatic umbrellas provides for the presence of a special tape, which may break during operation. But this is easy to fix. Unscrew the upper part (umbrella plug), remove the canvas and take out the nail-fixer, which is located in the upper assembly. Then disassemble the entire assembly. To do this, place your hand over the open tube and remove it very carefully. This must be done carefully and carefully, as there is a tight spring inside the assembly, which can rebound and injure you. Then replace the torn tape with a new one, reassemble the assembly and reinstall the retainer.
Quite often, the rod located at the point of the articulated joint fails. It is important to remember that such a part can be repaired only after loosening the connections on the umbrella and removing the hooks - otherwise you may be injured. To do this, cut a small 4 x 1.2 cm plate out of a piece of tinned tin and bend it lengthwise. You should get a trough-shaped mold. Check if it is deformed from the link halves. Straighten it if necessary. Then, tin the ends along the length and fit the overlay. Finally, solder the entire length of the repaired section.
If you cannot fix the retainer, you may need to replace it.
It happens that in modern umbrellas the retainer fails. Because of this, it is not held open. But such a breakdown is easy to fix.
Press down on the locking tab and with a sharp movement of your hand slide it to the side. Then remove the bent retainer, gently straighten it and put it back.
However, if the retainer is made of low-quality metal, then straightening it will help for a short while. Then it's better to just replace it. Find the old umbrella, remove the retainer from it and place it in the new umbrella. Assemble the design and test. If done correctly, the mechanism will work as it should.

Many people do not want to waste time fixing a broken umbrella and are looking for a replacement. But it is quite difficult to choose a product that will not break after several exits in rainy and windy weather. Yes, and it will not be cheap. Therefore, it will be better to save time and money by renovating your old umbrella. We hope our tips will help you do this.
Here's what to do if your umbrella is broken.The most detailed do-it-yourself umbrella repair master class (video)
Usually, many throw away umbrellas due to minor breakdowns, which, in fact, are easy to fix even for an inexperienced craftsman. Basically, the rods break at the point of their articulation, carried out using the axle. More often this happens with a large thrust at node “A” (Fig. 1), since this thrust in the open umbrella carries the main load, and even a slight lateral pressure on it leads to the breakage of the thrust, as a result of which the compression hook of the power spring is usually lost.
When starting to repair the traction, first of all, you should relieve the stress in the elements of the umbrella frame created by the power spring. For this, the upper end of the umbrella is abutted against some surface, for example, a door, and the power spring is compressed with the folded umbrella fixing sleeve so that all the hooks holding the spring in a compressed state can be freely detached from the rods. When releasing the hooks, the compression of the spring must not be loosened, otherwise other rods may break.
To repair a broken rod, you will have to make a connecting pad. To do this, a 45 × 13 mm plate should be cut out of 0.2 ... 0.3 mm tinned sheet (the width is given in excess, since it is not always possible to symmetrically bend the plate exactly along the longitudinal axis), turn the plate into a "trough" so that the latter was tightly put on the traction being repaired, to give the lining the desired shape (Fig. 2, a).
The broken and whole rods are freed from the fabric, if the first is deformed, it is straightened. The sections of the connecting rod ends, which will be located under the pad, must be tinned with excess. If the axle on the attached (whole) rod has no defects, the rod with the axle is installed in place, as shown in Fig. 2, b, the axle on both sides is tacked to the rod by soldering, a connecting plate is installed (Fig. 2, c). Having fixed in the desired position the end of the rod and the pad using a squeezing clamp, the pad is soldered to the rod without disturbing the axle soldering. The other half of the rod is firmly inserted into the pad (Fig. 2, d), after which the rod is fixed and the pad is soldered along its entire length. The joint is brought into proper form, checking the functionality of the articulated joint.
If the axle on the connecting rod is strongly bent and has any other defect, it is removed, a hole with a diameter of 1.5 mm is drilled in the lining, which coincides with the hole on the repaired rod, a wire is inserted into the hole, which will act as an axle. Further, the same operations for connecting the rods are carried out, which were described above. It remains to take out the wire, make an axis of the desired length out of it and connect it with the thrust axis. So that the axle does not fall out of the rods and does not catch the fabric, it is soldered to the pad on both sides (Fig. 2, e). The fastening of the fabric to the rods is restored. If there is easy access to the soldering point of the traction, it is better not to disconnect the fabric from the frame, but in order to avoid hot drops of tin from getting on the fabric, it is necessary to first put a gasket between the fabric and the soldering point. The breakdown in node B is eliminated in a similar way (see Fig. 1).
There are times when, after repair, umbrellas of this type do not fully fold.One of the reasons for this is the displacement of the lug inserts in the repaired nodes (especially in the A node), usually due to poor-quality crimping by the sidewalls of the rods. To eliminate such a defect, it will be necessary to move the eyelet to the desired place with light blows of a small hammer on the part of the eyelet protruding from the rod and again tightly squeeze the insert with the sidewalls of the rod. I draw your attention to the fact that grooves are made on the ear inserts for a more reliable connection with the rods (see Fig. 3, a).
In fact, broken rods are repaired only in the absence of intact rods from some other umbrella that cannot be repaired. It will not be difficult to separate the required traction from the umbrella frame. It is enough to cut off the flaring of the axles on a suitable rod from the samokal with a knife and disconnect it from other rods and assemblies. And the axles for the "new" thrust can be easily made of wire (or a stud) of the required diameter, not forgetting to solder the ends of the axle to the sides of the thrust.
In umbrellas with an extended power spring, along with the above breakdowns, the bushing of the power spring often cracks. Note that all the failed bushings that I dealt with could not be repaired, so to replace them I had to use suitable bushings from umbrellas of other designs. The new bushing can be installed both through the upper and lower parts of the umbrella shaft. It is only necessary to determine which pin is easier to knock out: either the pin that secures the handle, or the pin that holds the upper rod attachment point. First of all, of course, you need to free the rods from the broken bushing and remove the last one. The installation of the bushing through the upper part of the rod is carried out in the following sequence: the damping spring is shifted down (see Fig. 1), the pin is knocked out of the upper linkage attachment of the rods, this unit is removed and a new bushing is installed. The assembly of the umbrella, of course, is carried out in the reverse order.
All of the above repairs are performed with the power spring compression hooks removed. At the end of the repair, the presence of these hooks is checked, the missing number is made according to the shape of the existing ones, the sleeve for fixing the umbrella is folded down so that the cavity (slot) of the hook on it is in line with the protrusion of the retainer, hooks are hooked onto the sleeve, squeeze the power spring and hooks are inserted into the traction holes.
Opening and folding the umbrella, they check the correctness of its repair and assembly.
You can repair the mechanism in another way. It is a little simpler and takes less time to repair, but the ears are less durable. In this case, take a small piece of plywood (or a strip) with a thickness of about 5 mm and insert it into the slot of the fixing mechanism between the broken ears. On the remaining part of the lug in the plywood, mark and drill a hole for the axis, insert a stud of the appropriate diameter into the hole, install the plywood on the axis in the slots, weld on the mechanism body from the fragments of the ears or other suitable material or glue the missing parts of the ears to it. Next, from tin (stainless steel, copper, brass), cut out two strips half the width of the ear, bend them with a half-collar. Putting one half-collar on the ear, as shown in fig. 6, the semi-collar is heated with a soldering iron, gradually pressing it into the ear. We also press the second semi-collar into the other ear. It remains to take out the carnation-axis, remove the plywood, process the ears, and then assemble the mechanism. Do not forget to check the welding quality for strength. (For those who have not worked with plastic parts, I would like to inform you that such work is done in a well-ventilated area.)
For children's umbrellas with automatic opening, it happens that the hook protrusion at the retainer holding the umbrella in a folded state stops returning to its original position. This is due to the fact that the retainer is made of low-quality metal, and simply bends under load. You can quickly fix this problem. To do this, you have to press the locking lug (Fig. 7), move the lug towards the handle, pull the retainer out of the rod tube, bend the retainer at the bend point, and then insert the retainer into place. True, after a while the retainer will lose its shape again, so it is better to immediately replace it with a new retainer made of high-quality steel. If there is none, it is not difficult to make the retainer yourself from elastic metal.
For those who decide to do repairing umbrellas , I recommend making the devices shown in Fig. 8 and 9. Although they are primitive, they greatly simplify the repair process. So to form the linings (see Fig. 2, a), you will have to make a simple stamp. The die matrix (Fig. 8, a) is bent from sheet steel 1.5 mm thick. In the center of the bottom, a "trough" is formed with a beard or other suitable tool, a depression. The punch (Fig. 8, b), which has a protrusion in the center, is made from a strip of steel with a thickness of 3 ... 4 mm. When forming an overlay, a plate with a size of 45 ... 50 × 13 mm is placed on the matrix so that there is a depression under the center of the plate, a punch is placed on top and hit with a hammer. Everything. The cover is ready, you just have to work on it a little. By the way, the matrix described above is also useful for editing the rods, but the punch will have to be made a new one (Fig. 8, c). The deformed rod is placed in the recess of the matrix, after which it is straightened with a punch.

It is also necessary to make devices for compressing the power spring (Fig. 9). The principle of operation of this device is similar to the principle of operation of a simple screw press. Here, two crossbars "walk" along two guides (Fig. 10), one of which acts as a base, and the other acts as a slider, which can be moved by turning or unscrewing the thumbs on the guides where the M6 thread is cut. Each cross member consists of two halves (Fig. 10, a).
We will tell you a little how to compress a spring using this device. First, on each pin (guide), two halves of the jumper are put on and screwed on with a thumbscrew. The complete assembly of the device is carried out directly on the umbrella. The halves are connected with screws, as a result of which the resulting jumpers clasp the umbrella handle shaft. The fixture is now ready to compress the spring. You just need to spin the lambs. This simplifies the process of removing and installing the spring compression hooks described at the beginning of the text.

A little about the fabric. Broken ends of the rods tend to tear the fabric of the umbrella. Small holes can be sealed with the same cloth using BF-6 glue, which is sold in pharmacies, but it is easier to stick, as my friends do, a transparent self-adhesive film to the damaged area.
