The umbrella does not lock in the closed position. Here's what to do if your umbrella breaks. The most detailed master class on how to repair an umbrella with your own hands (video). Repair by installing a homemade copper wire rivet
During the rains, people use an umbrella to help them avoid getting their clothes wet. However, very strong winds or careless handling may deform the product. In this case, there is no need to rush and throw away the broken automatic umbrella; perhaps you can still repair it at home.
You will need
- metal tube with a diameter of 6 mm;
- stainless steel wire;
- tin plate;
- various parts from an unnecessary umbrella;
- soldering iron;
- pliers.
Repair steps
1. Grooved spokes are a common cause of machine umbrella failure. In this case, you need to find a metal tube with a diameter of 6 mm, then cut off a small piece of about 3 cm. You can use an antenna from a TV or radio for this purpose. The ends of the broken knitting needle need to be straightened, then put on the tube and squeeze the ends with pliers.
2. If the tubular rivets at the ends of the spokes are damaged, you need to insert a small piece of soft stainless steel wire into the hole, and then twist the ends.
3. If the tape on the automatic umbrella breaks, then you need to replace it. First, unscrew the top plug, then remove the panel and remove the retaining nail from the top assembly. After this, you need to remove the entire assembly, open the tube by carefully placing your hand under it. You need to be extremely careful, as there is a spring inside that can fly out. Now you need to take out the rollers and change the tape.
4. Also common cause The failures of the automatic umbrella are the rods; they break at the hinge points. Once all the clutches are loosened and removed from their hooks, the linkage repair can begin. Take a piece of tinned steel and cut out a small plate 40 by 12 mm. Bend the plate lengthwise to form a trough. All broken rod halves must be straightened. Now the ends can be tinned and the overlay can be installed; the damaged area must be soldered along the entire length.
5. It happens that the latch stops working and the umbrella cannot be kept closed. To do this, you need to press the locking tab and move it closer to the handle. Remove the broken retainer from the rod tube and straighten it out, then install it in its place. It is recommended to replace the fastener made of low-quality metal with a new one, since such a breakdown will bother you very often.

Usually, many people throw away umbrellas due to minor breakdowns, which are generally easy to fix even for an inexperienced craftsman. Mostly, the rods break at the point of their hinge connection, which is carried out using an axle. More often this happens with a large rod in node “A” (Fig. 1), since this rod in the open umbrella bears the main load, and even a slight lateral pressure on it leads to the rod breaking, as a result of which the compression hook of the power spring is usually lost.
Rice. 1. Design of the umbrella frame: A, B and C – places of the most common breakdowns; 1 – upper linkage fastening unit; 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
When starting to repair the rod, first of all 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, for example, against a door, and the power spring is compressed with 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.
Rice. 2. Repair of broken rods (using a lining): a – lining; b, c and d – sequence of operations during repair; d – repair with installation of a new axle; 1 – whole thrust; 2 – broken rod; 3 – overlay
To repair a broken rod, you will have to make a connecting pad. To do this, you should cut out a plate measuring 45×13 mm from 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), turn the plate into a “trough” so that the latter was tightly put on the rod being repaired, giving the lining the desired shape (Fig. 2, a).
The broken and intact rods are freed from the fabric; if the first one is deformed, it is straightened. The areas of the connected ends of the rod that will be located under the lining must be tinned in 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 secured to the rod by soldering, and a connecting plate is installed (Fig. 2, c). Having fixed the end of the rod and the cover in the desired position using a compression clamp, the cover is soldered to the rod without disturbing the soldering of the axle. The other half of the rod is firmly inserted into the pad (Fig. 2d), after which the rod is fixed and the pad is soldered along its entire length. The joint is brought into proper shape, checking the functionality of the hinge joint.
If the axis on the attached 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, coinciding with the hole on the rod being repaired, and a wire is inserted into the hole, which will act as an axis. Next, carry out the same operations for connecting the rods that were described above. All that remains is to remove the wire, make an axis of the required length out of it and connect it with the rod axis. To prevent the axle from falling out of the rods and clinging to the fabric, it is soldered to the pad on both sides (Fig. 2e). 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. The breakdown in node B is repaired in the same way (see Fig. 1).
Rice. 3. Repair of broken rods (using an insert and an overlay): a – insert; b – overlay; c, d and e – sequence of repair operations
Umbrellas in which the frame elements are made of thicker steel (in this case, the rods have narrower sidewalls), the broken rods in nodes A, B and C are connected using plug-in lugs, which are pressed against the sidewalls of the rods. For such umbrellas, breakage of the rods most often occurs in node B (see Fig. 1), since in this place the strength of the rod 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. 3, a. 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 is that when it is installed in place, the hook hook moves freely in the resulting cavity, and the insert itself does not interfere with the compact folding of the umbrella. To enhance the strength of the traction at the point of failure, it is still necessary to make an overlay from tinned sheet metal with a thickness of 0.2...0.3 mm (Fig. 3, b). Having made the fasteners, all that remains is to straighten the broken rod, tin the finished connecting insert with a thin layer of tin, insert 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. 3, c), and crimp the end of the insert traction sidewalls. 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 an overlay on the place 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 overlay to the rod.
Rice. 4. Mechanism for fixing the umbrella (manual) when opened: 1 – rod fastening unit; 2 – clamp; 3 – eye
There are cases when, after repair, umbrellas of this type do not fold completely. One of the reasons for this is the displacement of the ear inserts in the repaired units (especially in unit A), which usually occurs due to poor-quality crimping of the sidewalls of the rods. To eliminate such a defect, you will have to lightly hit the part of the eye protruding from the rod with a small hammer to move the eye to the desired place and again press the insert tightly with the sides of the rod. Please note that in order to more securely connect them to the rods, notches are made on the ear inserts (see Fig. 3, a).
In fact, broken rods are repaired only if there are no intact rods from any other umbrella of a similar design that cannot be repaired. Separating the required rod from the umbrella frame is not difficult. 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. And the axles for the “new” rod can be easily made from wire (or a nail) of the required diameter, not forgetting to solder the ends of the axle to the sides of the rod.
For umbrellas with an extended power spring, along with the above-mentioned breakdowns, the power spring bushing often cracks. I note that all the failed bushings that I dealt with were beyond repair, so to replace them I had to use suitable bushings from umbrellas of other designs. You can install a new bushing either through the upper or lower parts of the umbrella rod. You just need to determine which pin is easier to knock out: either the pin that secures the handle, or the pin that holds the upper linkage attachment. First of all, of course, you need to free the rods from the broken bushing and remove the latter. Installation of the bushing through the upper part of the rod is carried out in the following sequence: move the depreciation spring down (see Fig. 1), knock out the pin from the upper attachment point of the rods, remove this unit and install a new bushing. Assembling the umbrella, of course, is done in the reverse order.

Rice. 6. Option for repairing the umbrella fixation unit in the open form (using surfacing and half-clamps): 1 – surfacing; 2 – half clamp
All of the above renovation work performed with the power spring compression hooks removed. Upon completion of the repair, check the presence of these hooks, make the missing number of them in the shape of the existing ones, install the umbrella fixation sleeve in a folded form so that the cavity (slot) of the hook on it is in line with the latch protrusion, hook the hooks to the sleeve, compress the power spring and insert the hooks into the holes of the rod.
By opening and folding the umbrella, check the correctness of its repair and assembly.
For umbrellas with manual opening, especially with a three-stage rod, in the mechanism that fixes the umbrella when opened, the eye in which the locking axis is installed often breaks due to excessive tension (in Fig. 4, the breakage point is shaded). If it is impossible to replace a failed mechanism, it can be repaired by making a clamp from 0.2...0.3 mm tin-plated sheet. It is clear that the dimensions of the workpiece for the clamp depend on the dimensions of the mechanism sleeve. In Fig. 5, and I gave the dimensions of the clamp blank for the fixation mechanism in the open form of my umbrella, where the size of 35 mm is the distance on the blank from eye to eye, measured along the outer diameter of the bushing. 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) and, applying the edges to the ears of the mechanism, the contours of the ears are transferred to the edges and the location of the hole of the latch axis is precisely marked. Remove “extra” areas on the folds. To increase the strength of the clamp ears, it is better to solder to them plates cut to their size and shape (Fig. 5,b), not forgetting to drill holes in the bends. All that remains is to bend the workpiece, without allowing distortion, around the tube (rod), the diameter of which corresponds to the diameter of the bushing of the fixation mechanism, 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. 5, c.
Rice. 7. Design of the latch: 1 – locking protrusion; 2 – handle tube; 3 – hook protrusion
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 plywood (or strip) approximately 5 mm thick and insert it into the slot of the fixation mechanism between the broken ears. Along the remaining part of the ear in the plywood, 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 the missing parts of the lugs onto the mechanism body or glue them to it. Next, two strips half the thickness of the ear are cut out of tin (stainless steel, copper, brass), and bent with a half-clamp. By placing one half-clamp on the ear, as shown in Fig. 6, heat the half-clamp with a soldering iron, gradually pressing it into the ear. We also press the second half-clamp into the other ear. All that remains is to remove the stud-axle, remove the plywood, process the ears, and then assemble the mechanism. Don't forget to check the welding quality for strength. (For those who have not welded plastic parts, I inform you that such work is performed in a well-ventilated area.)
With children's umbrellas with automatic opening, it happens that the protrusion of the hook at the latch that holds the umbrella when folded stops returning to its original position. This is due to the fact that the clamp is made of low-quality metal and simply bends under load. This kind of problem can be fixed quickly. To do this, you will have to press the locking protrusion (Fig. 7), move the protrusion towards the handle, pull the latch out of the rod tube, bend the latch at the bend point, and then insert the latch into place. True, after some time 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 you don’t find one, it’s easy to make a retainer yourself from elastic metal.
For those who are thinking about doing umbrella repair, I recommend making the devices shown in Fig. 8 and 9. Although they are primitive, they greatly simplify the repair process. So, to mold the overlays (see Fig. 2,a), you will have to make a simple stamp. The die matrix (Fig. 8a) is bent from sheet steel 1.5 mm thick. In the center of the bottom of the “trough”, a depression is formed with a beard or other suitable tool. The punch (Fig. 8,b), which has a protrusion in the center, is made from a strip of steel 3...4 mm thick. When forming an overlay, a plate measuring 45...50×13 mm is placed on the matrix so that there is a recess under the center of the plate, a punch is placed on top and hit with a hammer. All. The overlay is ready, all that remains is to work on it a little. By the way, the matrix described above is also useful for straightening the rods, but the punch will have to be made new (Fig. 8, c). The deformed rod is placed in the recess of the matrix, after which it is straightened with a punch.
Rice. 8. Die for making linings and straightening rods: a – matrix; b and c – punches
It is also necessary to make devices for compressing the power spring (Fig. 9). The operating principle of this device is similar to that of a simple screw press. Here, two crossbars “run” along two guides (Fig. 10), one of which acts as a base, and the second as a slider, which can be moved by turning or unscrewing the wings on the guides where the M6 thread is cut. Each crossbar consists of two halves (Fig. 10, a).
Rice. 9. Device for compressing the power spring: 1 – crossbar (jumper); 2 – split washer; 3 – power spring bushing; 4 – sleeve for fixing the umbrella when folded; 5 – pin (guide)
We’ll tell you a little about how to compress a spring using this device. First, two halves of the jumper are put on each pin (guide) and screwed on the lamb. Full assembly devices are made directly on the umbrella. The halves are connected with screws, as a result of which the resulting jumpers wrap around the rod of the umbrella handle. The device is now ready to compress the spring. You just need to tighten the screws. This simplifies the process of removing and installing the spring compression hooks, described at the beginning of the text.

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

First steps. How to open and close?
If you know what type of mechanism your umbrella has, read the “scientific instructions” below; if you don’t know, follow these steps step by step:
Step 1. Remove the cover, unfasten the strap and shake the umbrella slightly so that the folds of the canopy material do not stick to each other.
Step 2: Look for the button. For folding umbrellas, the button is located on the handle; for cane umbrellas, the button is a lock at the base of the rod.
Step 3. Position your hand so that the suddenly opened dome does not cause damage to you or anyone else.
Step 4: Click the button. This is not a touch phone, press the button confidently. The umbrella didn't open? Try again or ask a more experienced friend. Didn't open up again? If you did everything correctly, what you have in front of you is most likely a semi-automatic umbrella (the button is used to close). Is there no button? Fine. With your other hand, grab the slider and move it in the direction “away from the handle” until the latch clicks.
Congratulations! The umbrella is open.
Now let's close...
For buttonless umbrellas. Find the latch on the slider, press it so that the slider goes “down”. Fold the umbrella all the way.
For push-button ones. Press the button confidently. The dome will fold, and all you have to do is fold the rod (if it's not a cane). The rod folds in two ways: either pull the slider towards the handle until it stops, or fold the umbrella by resting the palms of both hands with different sides rod.
You press, but it doesn’t fold? Look for a lock on the slider. Available? Press and fold the umbrella manually.
Scientific instruction
If you do not know what type of mechanism the umbrella has, check this information with the seller.
Important! Before opening, slightly straighten the folds of the canopy; after closing, fold the umbrella without twisting the knitting needles, as this leads to breakdown.
- Mechanical umbrella- opens and closes manually. There are no buttons on the handle of this umbrella. Grab the slider on the rod and move your hand away from the handle. In this case, the dome will gradually open; bring it to a click by moving the slider through the “lock”. Such an umbrella is closed by pressing the same “latch” and manually folding the rod by the slider.
- Umbrella machine- opens by pressing a button on the handle. It closes manually - grab the slider and pull it towards the handle, which will first fold the dome and then the rod.
- Semi-automatic- opens manually. Grab the slider on the rod and pull it up towards the dome until it clicks. This umbrella closes by pressing a button. Pressing the button collapses the dome, and the rod will need to be folded manually by pulling the slider towards the handle.
- Full automatic- opens and closes by pressing a button (usually for such umbrellas the button is marked with two arrows, but this is not necessary). Closing occurs in two stages - pressing the button when the umbrella is open will collapse its dome, and you fold the rod manually by pulling the slider towards the handle.
How to dry. Subtleties of ordinary business
Long service will be ensured by proper drying after rain. Many people perform this simple action incorrectly, without even realizing the error.
Do not cover a wet umbrella or leave it wet for a long time. This will lead to rapid wear of the dome fabric, as well as the appearance of rust on the metal frame.
At first open the umbrella, place it open away from heat sources, let the water drain.
Do not wait until the umbrella is completely dry; dry it in a half-opened state (not fastened with the strap, but also with the canopy not opened). You need to hang it on some kind of hook. As the fabric dries under tension, it stretches. This will cause the frame to become loose, the fabric will be loosely stretched, and the umbrella will lose its attractive appearance.
Do not dry the umbrella near radiators or heating devices. The fabric will shrink and the umbrella will become unusable.
After drying, the umbrella should be shaken thoroughly and the fabric carefully folded around the frame.
Except proper drying, there are others, no less important rules, following which will significantly extend the life of your umbrella.

Important! What to do if the umbrella is blown over by the wind?
Don't be alarmed if the umbrella gets twisted by the wind, and don't try to return it to its normal position with your hands.
Do it in the usual way, in accordance with the mechanism. For example, if it is a full automatic machine, then simply press the button, fold the mechanical one by pulling the slider towards the handle.
If your umbrella accidentally gets dirty, don't worry. It can be cleaned and your weather protector will be as good as new!
How to clean umbrellas?
Most umbrellas are made from polyester. But there are also products made from other materials. For example, transparent umbrellas are made from polyvinyl, and wedding umbrellas are made from cotton and guipure. Unusual materials require special care.
Features of caring for transparent umbrellas

Probably every person uses an umbrella, since it rains in almost all places on our planet. And of course, almost everyone has encountered the fact that sooner or later an umbrella breaks.
– probably these two questions are of most interest to umbrella owners. 
An umbrella usually consists of the following main parts - a handle with a button, sliding pipes (the number may vary, but most often there are 6 or 8 of these pipes), a lower support for the spokes, an upper support for the spokes to which the main cord of the umbrella is attached, a thick short and thin long springs, a plastic tube - the upper part of which is thickened, has a wheel and is inserted into the upper support. 
If it turns out that the automatic umbrella is broken, then there is no need to rush to take it to the workshop or in no case should you throw it away. You can also repair the umbrella yourself.
Depending on what exactly is broken, you will need the following things for this: ready-made parts from another umbrella, pliers, stainless wire, a soldering iron, a metal tube with a diameter of 6 centimeters.
The most common types of damage to umbrellas are:
Automatic umbrella does not fold
Grooved spokes break very often.
In order to fix this you need to take metal pipe 6 centimeters in diameter and cut a piece from it approximately 3 centimeters in length. Then you will need to straighten the ends of the knitting needle that broke, then put a cut piece of tube on it and compress these two ends with pliers. 
— the tubular rivets at the ends of the spokes are damaged. In order to fix the umbrella in this case, you need to insert a small piece of soft stainless steel wire into the hole, and then you will need to twist the ends.
— the rod broke at the point of their hinge connection.
You need to cut a small plate of 20 by 12 mm from a piece of tin and bend it along its length so that it looks like a trough. After this, you will need to tin the ends and install the overlay itself. Then you need to take a soldering iron and use it to solder the place where the umbrella was repaired. 
— often in umbrellas that open automatically there is a problem that the latch fails to work. It is the latch that holds the umbrella when it is closed.
In order to eliminate this, you need to press the locking protrusion and move it closer to the handle. Then you need to remove the faulty latch from the tube, straighten it - and then install it back in its place.
And you can also look video Repairing a semi-automatic umbrella with your own hands
The folding umbrella with automatic opening and closing is easy to use. One press of a button on the handle - and now you have a fully open umbrella in your hand and you are ready to head out into bad weather. Pressing the button again will also automatically close the umbrella canopy and you will only have to push the stem in and put on the cover after drying.
However, one wrong move can ruin the entire mechanism, and to prevent this from happening, let’s figure out how it works and works.
When the umbrella is folded, the handle under the button (1) simultaneously holds: the telescopic rod (2) when folded and the anchor (8) in the sleeve (9). Inside the rod, in a tense state, there is a thread, one end of which is attached to the anchor, and the second through the roller (11) located in the crown (6) is attached to the runner (12).
Opening an umbrella
The first press of the button (1) releases the telescopic rod (2) of the umbrella, which, under the action of the spring (3) compressed inside the rod, moves forward.
The thread (7), attached to the rod (2) of the crown (6) through the roller (11), pulls the slider (4) up. Supporting spokes (13) are attached to the outside of the runner, which also move forward and open the umbrella dome structure.
Compensation springs (10) are located on the frame spokes
Note: compensation springs are available for umbrellas with a fully automatic mechanism and for umbrellas with automatic closing (folding the canopy). They serve to counteract the force of the spring (3) at the moment the dome opens, and also participate in its folding when the button is pressed. The necessary and sufficient number of these springs is calculated by the manufacturer for each umbrella model. The number of springs (10) depends on the size of the dome and the material used. Compensation springs may not be on every spoke, and as we have already noted, their number depends on the model and is determined by the manufacturer. The absence of a compensation spring on the spoke is not a defect. For example: umbrellas with manual opening do not have these springs.
The force of the spring (3) in the telescopic rod is insignificant, but exceeds the force of resistance to opening the dome. The compensation springs (10) on the spokes of the umbrella stretch when the canopy opens. Due to this, the umbrella opens smoothly and does not suddenly “shoot out”. In the open state of the dome, the compensation springs (10) are stretched.
Folding the canopy and folding the umbrella
When you press the button (1) a second time, the anchor (8) is released from the sleeve (9). The thread (7) is loose and no longer holds the slider. The runner (4) with the supporting spokes (13) attached to it can now move freely.
The springs (10) on the spokes compress, returning to their normal state, and fold the umbrella canopy. All you have to do is push the rod in to compress the main spring and return the armature to the sleeve located in the handle.
Full automatic - features of the mechanism. What not to do.
Remember! The folding umbrella is fully automatic and opens and folds only by pressing a button in the handle of the umbrella!
The first press (opening the umbrella) unlocks and extends the telescopic rod, the canopy opens.
The second press (folding the canopy) releases the anchor and the canopy folds.
Important rule! The umbrella is fully automatic - it opens and folds only by pressing a button located in the handle.
Forbidden! Use your hands to open and fold the canopy of the umbrella. Grasp the umbrella slider with the automatic mechanism to bend it. These actions lead to breakage of: fixing parts, stretching or breaking of the thread (inside the telescopic rod), as well as breakage of its attachment points.
When opening:
Let's say you forgot that your umbrella is fully automatic and did not press the button. Push the slider forward from the umbrella handle with your hand. The umbrella will not open because... the rod is fixed and will not extend. If you push the slider with force, the rod lock located in the umbrella handle will break. The umbrella may not open completely, but you won’t be able to fold it by pressing a button.
When folding:
The first press of the button opened the umbrella. Let's say you forgot that your umbrella is fully automatic and in order to fold the canopy you did not press the button, but forcefully pulled the slider towards the handle. Simultaneously with the folding of the dome, the telescopic rod begins to fold. The anchor is tightly clamped in the sleeve. The load (created by you) can break the anchor, stretch or break the thread. Depending on where the thread breaks, this breakage may prevent the canopy from folding and the umbrella from folding. When the thread is stretched, the umbrella dome does not open completely.
Signs of breakage of the latch, thread attachment points, or its breakage (when pressing the button):
When opening, the umbrella “shoots”, a rope (thread) of the mechanism appears, the canopy does not open.
When closing there is a click and the dome does not fold.
Breakdown options:
1 - the thread is pulled out or torn,
2 - one of the parts to which the thread is attached is broken,
3 - breakdown of the rod (2) or anchor (8) fixation parts of the umbrella handle, or the entire fixation device is damaged.
Advice: Choose umbrellas only from trusted brands, follow the rules of operation, care and storage.
