Repair of children's mechanical toys

Good day to all family men and those who are preparing to become one !!!
New Year has passed and children, of course, play with donated toys. But it also happens that they break them 🙁
There are toys that, after a breakdown, either cannot be repaired, or there is no desire, etc. etc. , but by and large, many think that it is easier to buy a new one, BUT it is not always possible to find the same toy that was broken, and if the person who gave your child a wonderful toy does not remember where he bought it after the holidays? So my youngest played carelessly with a musical mechanical toy. .. broke off a foot!

  • engraver (drill)
  • Phillips and two flat clock screwdrivers
  • superglue
  • degreaser with rags
  • sandpaper
  • plastic sheets (no more than 1 mm thick) < br>
  • screwdriver (or drill)

A pleasant, unnerving melody and funny movements from side to side, in general, the whole family liked this toy so much, and so did I, that I decided to repair (restore) it, and not throw it away! Many toys were thrown out because of the annoying monotonous melody. < br> In the video you can see how it moves to the melody!
The body is very voluminous, and it can be disassembled quite easily, only six screws.

And here is the mechanism, or rather the case with the mechanism …
The wires are short and must be handled very carefully! The soldering of the wires turned out to be excellent, they are well soldered to the contacts, but once again it is better not to check their reliability …
Repair of children's mechanical toys And the details of the “legs” …
Repair of children's mechanical toys To remove a broken part for repair, you need to unscrew the screw (or, as you can also call it, the counter-screw) , it does not fix the moving part “tightly”, but only restricts it with its head (like a self-tapping screw with a press washer), due to this, the part moves freely, but does not jump off.

Repair of children's mechanical toys It is also necessary to pull out a piece of the broken leg from “boot” …
Repair of children's mechanical toys Repair of children's mechanical toys At first I thought that the sole is held by glue, but it's just something like latches …

Although it happens the other way around.
 Repair of children's mechanical toys The leg itself in the boot is held by a double latch (see the photo).
Repair of children's mechanical toys It is problematic to disconnect such connections if the whole shoe is in collection!
But if you show ingenuity, then everything can be done …
On the sides of the leg, I passed flat clock screwdrivers.
Repair of children's mechanical toys I held these screwdrivers with one hand and pushed out a part of the leg with my finger, or you can do it differently: with one hand holding the boot on weight and hold two screwdrivers with your finger, and the other pull out the broken part from below.
As a result, he removed the fragment without damage and the latches were all preserved.
Repair of children's mechanical toys These two parts will have to be combined together, in other words, restored.
Repair of children's mechanical toys Before repair, you need to pay attention to some factors!
Namely:

  • the oblong holes in which the legs move are narrow and there is not enough backlash, if the idea comes to glue or solder a plate on top, i.e. the part will become thicker, in this case it will be necessary to expand the “body”, while its appearance will deteriorate.
  • pay attention to the detail itself !!! Will the first point be avoided, i.e. part thickening and main body changes. In my case, it turned out to be easier, I'll show you everything further in the article.
  • what kind of plastic is used in the manufacture of this part! In fact, it is extremely rare for manufacturers to mark plastic, and what is currently unknown in the hands! print on the packaging, on a cardboard box or bag, what was the toy in at the time of purchase, what kind of plastic is used, but from personal experience I can say that several plastics can be used in the manufacture of parts for such toys, and finding out is extremely unhealthy (there is information on how to find out the type of plastic at home, which I do not advise, although if you have your own laboratory, then of course! please!)
  • understand how to repair it and why! those. what tools to use.

This plastic DOESN'T ADHESE AT ALL !!!

Yes, I degreased !!!
On the other hand, the glue at least more or less kept the parts so that you could glue the “amplifiers” from the plates on the sides.
