ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a driving-in tool for the correct mounting of furniture fittings provided with a rotatable lever.
Driving-in tools for the insertion of furniture fittings can be used with mounting devices of drills which simultaneously serve to press in mounting plates or cup-shaped hinge parts into the cut mounting and dowel holes. Such a drill and mounting device is known from DE 35 08 521 A. On the other hand, driving-in tools are already known for the manual mounting of furniture fittings. For example, connection fittings made of plastic can be sunk through furniture fittings into pre-drilled mounting holes by press fit. Here, the driving-in tools are suitable to distribute the press force in the correct manner without any damage to the furniture fittings.
A fitting element for fittings is known, for example, from DE 295 11 216 which can only be locked in place in a pre-drilled borehole of an assembly part by throwing or pressing down a lever. Here, the fitting element consists of a conical, essentially cylindrical section which is provided with a radial breakthrough in which two spreaders are guided for travelling out in opposite directions over the cylindrical jacket contour and for being pulled back in its region and of a link or slide whose one end can have pressure applied to it by an actuating lever for its motion and whose other end is fitted to a bolt guided in axial slits of the cylindrical section, which bolt penetrates slots of the spreaders positioned in such a way that said spreaders are travelled in and out by a rotation of the link or lever. While such fitting elements allow the mounting of prefabricated furniture parts without any special tools such as screwdrivers or similar, they can, however, be actuated unintentionally by accident prior to the final pressing in of the fitting as the rotating lever is supported near the surface on the fitting and is generally rotatable in the same direction of pressing in. This has the consequence that the fittings can be unintentionally fitted in an incorrect position.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a driving-in tool for furniture fittings provided with at least one rotating lever, which driving-in tool simplifies the easy and correct mounting of the furniture fittings in the pre-drilled boreholes of the furniture parts.
In accordance with the invention, this object is solved by a driving-in tool in accordance with the a driving-in tool for a furniture fitting part which can be fitted in place by at least one rotating lever, by combination with the the driving-in tool possessing a centering part shaped in accordance with the fitting part to be connected and serving as an insertion guide and a spring or spring-loaded holding part supporting the lever in its open position. Accordingly, the driving-in tool possesses a centering part shaped to correspond to the connecting fitting and serving as an insertion guide and a spring or spring-loaded part supporting the rotating lever in its open position.
The furniture fitting remains in a fixed, pre-mounted position on the driving-in tool during the mounting, with the actuating lever of the furniture fitting being turned in its open position and being supported in this by the holding part of the driving-in tool. The furniture fitting is not directly actuated during mounting so that any unintentional throwing of the actuating lever is excluded. Only when the fitting part has been put into its completely inserted mounting position and has been fixed in this position by the lever now having been intentionally thrown by overcoming the spring force of the holding part can the driving-in tool again be removed from the fitting part. The correct mounting position is thus ensured.
Preferred aspects of the invention can be seen from the further description herein.
The invention can advantageously be further developed by providing on the driving-in tool another actuating lever which acts on the actuating lever of the furniture fitting part and which enlarges the latter's lever arm and thus reduces the force to be exerted. When inserting the fitting parts provided with the actuating levers into the furniture parts, no pressing force is required so that manual mounting can generally be performed without any great force. When locking the fitting parts in position in the associated boreholes, however, force must be exerted to throw the at least one actuating lever which force can lead to finger fatigue, particularly in the event of extensive mounting work. Here, a remedy is created thanks to the aspect of the invention described above by which the force application to throw the actuating lever for the furniture fitting is reduced.
