Definitions

• the invention relates to a lock with a lock cylinder, which can be actuated with a key and has a driver tongue, with a pushing movement-carrying element and with a transmission device for transmitting the movement of the driver tongue to the element, in order to move this by means of a device into the closed position or To move open position, wherein the transmission device has a first gear rotatably arranged about the lock cylinder and rotatable with the driver tongue.
• Such locks are known. Among other things, they serve to lock window or door sashes with the frame. However, these locks or the transmission devices of these locks have a large number of toothed wheels. Usually there are up to seven gears that are necessary for the movement of the bolt and are used. In addition, this lock often has an excessive backset. It is quite possible that the first gear is a completely closed gear. However, the assembly is relatively complex.
• the invention is therefore based on the object of specifying a lock of the type mentioned, which ensures technically simple means that it is always safe to operate and at the same time has small dimensions and is inexpensive to produce.

• the essence of the invention is that only three elements are used to transmit the movement of the driver tongue to the element.
• the rotary movement induced by the driver tongue is transmitted to the first gear, which meshes with the at least second gear. Due to the movement of the first gear, the second gear and thus also the shaft are set in rotation, which in turn also leads to a movement of the device. Since the at least one shaft is arranged transversely to the lock cylinder axis, very small backset dimensions can also be achieved for the first time.
• this second gearwheel has such a position that it can be immersed again or meshed with one another is at least made more difficult since the corresponding teeth of the first and second gearwheels are no longer in the intended position.
• this can be avoided by providing the outwardly facing surface of the driver tongue with a toothing that matches the first gear. To do this, however, it is necessary to subject this surface of the driver tongue to additional machining to remove the teeth.
• the shaft is provided with a third gearwheel or spindle device which is at a greater distance from the second gearwheel than the recess in the region of the free end of the driving tongue and also with the first gearwheel combs. Since the distance between the second and third gear is larger than the recess in the area of the outer edge, one of the second and third gears always meshes with the first gear.
