Guide for gear rods, of locks for windows made of wood or plastic

The innovation concerns a guide for transmission rods of locks for windows made of wood or Plastic. Such closures consist of a gear rod and a faceplate.

In known closures, the gear rod

on the faceplate by bolts or the like. Guided. Closures of the type in question are like that constructed that the window manufacturer from a standard size by shortening the faceplate and the Gear rod can produce a lock for the required window size itself. In the shortened area, the gear rod can no longer be guided on the faceplate. this brings difficulties, since once the degree of reduction to avoid a large number of standard sizes should be as large as possible, and on the other hand, there is a danger due to the lack of guidance in the reduction area there is that the gear rod kinks under extreme load.

In the case of previously known closures, there are therefore additional fastening holes in the area of shortening intended. With certain shortening dimensions, no screw could be screwed into these fastening holes will. A sticker was therefore supplied for these cases in order to

cover holes. If the craftsman inadvertently turns in a screw anyway, that's the job Lock blocked.

It should also be mentioned that if the gear rod buckles, the everting can also be pushed up.

These difficulties should be eliminated by the innovation. It is proposed to use a guide which has a hollow chamber. The guide is pushed with the hollow chamber over the gear rod. In addition, the side walls of the guide should be designed like a sawtooth. It is particularly advantageous if webs are provided on the guide to adapt to the depth of the gear slot.

The guide is pushed over the gear rod and when installing the lock in the gear groove depressed. Due to the sawtooth-like side walls, it gets caught in the

Gear groove and prevents the gear rod from buckling even under very heavy loads.

With extremely shortened dimensions, there is no longer any risk of kinking. In this case the guide can be omitted will.

The guide can be used in the same way for windows made of wood or plastic.

An embodiment of the innovation is shown in the drawings.

the guide 1 are designed like a sawtooth. Appropriate if the guide 1 still has webs 6. Through the webs 6, the guide 1 is at the depth of the Gear slot 5 adapted.

The guide 1 is pushed over the gear rod 3 during the assembly of the lock. The closure can be shortened in a known manner. When the lock is pressed into the gear groove 5, the sawtooth-like side walls k of the guide 1 hook into the guide groove 5. This prevents the gear rod 3 from buckling even under heavy loads.

The faceplate 7i that covers the lock, does not need to have any fastening holes in the area of the shortening of the fastener. The end the faceplate 7 is held in a known manner by the adjacent Beschlagted1.
