Description

  The present invention includes a guide rail that can be attached to a main body of furniture, an automatic pull-in device that is attached to the guide rail, and a traveling rail that can be attached to a drawer, that is, a drawer of furniture, and the like. And a drawer guide having an automatic retracting device for drawers, such as furniture drawers.

  Numerous different variants are known for drawer guides of the type described above.

  The basic features of such a drawer guide are an automatic retracting device and an actuator that controls the automatic retracting device.

  An automatic retraction device is a force storage device that is tensioned by coupling with an actuator when a drawer, i.e. a furniture drawer, is pulled out of a closed position. This is done by a relatively short extraction stroke, after the force storage device is fully tensioned, the actuator moves the automatic retractor to a position where the energy storage device locks into the tensioned position. . Thus, further displacement results in the actuator being separated from the automatic retracting device. The drawer, i.e. furniture drawer, etc. can then be moved to the fully withdrawn or open position without further affecting the automatic retracting device. Later, when the drawer, i.e. furniture drawer, etc. is moved back to the closed position, the actuator reaches the contact area with the automatic retracting device at the predetermined displacement position of the running rail, so that the blocking of the force storage device is canceled. The actuator is again coupled to the automatic retracting device. Due to this coupling, the tensioned force storage device's own force is utilized to automatically move the drawer, i.e., furniture drawer, etc., to the final closed position.

  In the case of known drawer guides of the type described above, the actuator is fixedly connected to the running rail, preferably by welding.

  This has various drawbacks.

  For one thing, the welding operation can have an adverse effect on the appearance and corrosion properties of the running rail, and, in part, the manufacturer must decide in advance whether or not the running rail should be equipped with an actuator. It must be done. For example, the subsequent installation of the actuator by the final customer during the installation of a subsequent automatic retracting device is considered impossible with conventional devices, or only when considerable inconvenience is tolerated. Conceivable.

  The object of the present invention is to improve the pull-out guide of the type described above in such a way that the mounting of the actuator to the running rail is greatly simplified and can be easily performed later by an intermediary or the final customer. is there.

  This object is achieved by the actuator being fixed to the running rail in a locking manner.

  Thus, it is only necessary to prepare the traveling rail so that the actuator can be locked to the traveling rail. At the time of manufacture of the entire drawer guide, perhaps at that point in time, it is not certain whether the corresponding travel rail will be used for a drawer guide with or without an automatic retracting device, so the actuator itself There is no absolute need to attach it to the drawer guide in advance, so it can be attached at a different location at a later time if desired.

  As a result, the entire manufacture of the drawer guide is significantly facilitated since it is not necessary to separate from the beginning a travel rail with actuators and a travel rail that does not require actuators.

  Furthermore, the object of the present invention is that the actuator and the closing stopper inserted in the front region of the traveling rail are attached to the traveling rail as a whole by engaging the closing stopper with the traveling rail and / or fixing it by friction. This can be achieved by forming a subassembly.

  In this technical solution as well, since the subassembly composed of the actuator and the closing stopper can be fixed to the traveling rail at a later arbitrary time in a simple manner, It has the advantage that there is no absolute need to pre-attach the actuator to the drawer guide.

  According to a further development of the invention corresponding to the first proposed technical solution, an actuator is attached to the front end region of the running rail.

  This is beneficial in that there are no space related problems, especially in the case of a post-installation of the actuator. Because the traveling rail can always be moved to the pull-out position so that the front end area of the traveling rail is completely freely accessible, and therefore the lockable actuator can be installed without any problems It is.

  In a particularly advantageous embodiment corresponding to the first proposed technical solution, the actuator is locked to a closure stop inserted into the front end region of the running rail.

  The advantage of this measure is in particular that the locking device can be designed to be relatively stable while still being sufficiently elastic. This is because it is not necessary to fix the locking device to the thin region of the traveling rail, and there is enough space in the region of the closing stopper to perform a sizing with a margin.

  The actuator is provided with two restraining hooks extending at least one through the closure stopper in the region of the opening, and these restraining hooks are connected to the web of the web located at the rear end of the closure stopper by a restraining projection provided at the free end. It is beneficial to reach behind the web or behind the web between the two openings in a locking manner.

  In this case, the closure stopper and the actuator itself are advantageously constructed as plastic parts. This allows the connection between the closure stopper and the actuator to be dimensioned in a relatively accurate manner and with a relatively small tolerance. Another advantage of using plastic materials, especially for the actuators, is that the generation of noise during operation of the automatic retractor is kept relatively small.

  Further features of the invention are the subject of further dependent claims.

  Embodiments of the invention are illustrated in the accompanying drawings and are described in detail below.

FIG. 3 is a perspective view of a drawer guide according to the present invention in a closed position where the automatic retracting device is pressed together; It is a similar perspective view, but the automatic pull-in device is in a fully tensioned state while the running rail is pulled out partway. FIG. 5 is a further perspective view of the drawer guide after the actuator has left the automatic retracting device. It is sectional drawing of the front-end area | region of the running rail of a drawer guide, and the running rail is equipped with the actuator. FIG. 5 is a view in the direction of an arrow V rotated by 90 ° with respect to the position shown in FIG. 4. It is a perspective view of an actuator, and is a perspective view of the direction of the connection area | region with respect to the running rail of an actuator. FIG. 2 is a perspective view corresponding to FIG. 1 for a drawer guide having an automatic retracting device according to a further embodiment of the present invention. FIG. 8 is a perspective view of the front end region of the traveling rail according to FIG. 7 equipped with an actuator. FIG. 5 is a perspective view of a subassembly including an actuator and a travel rail closing stopper. FIG. 10 is a view in the direction of the arrow X in FIG. 9, which shows a drawer (not shown in detail) restraining hook very schematically.

  1-3 have the reference number 1 as a whole, a guide rail 2 that can be attached to the furniture body, a traveling rail 3 that can be attached to a drawer, i.e., a drawer of furniture, and a traveling rail 3. 1 shows a drawer guide basically comprising an automatic retracting device 4 controlled by an actuator 5 connected to.

  The actuator 5 includes a control protrusion 6 that engages with the driving device 7 of the automatic retracting device 4 when the drawer guide 1 is completely pressed together (corresponding to a closed position such as a drawer, that is, a drawer of furniture). This is shown very clearly in FIGS.

  FIG. 2 shows the traveling rail 3 in a state where the traveling rail 3 is displaced with respect to the guide rail 2 by a stroke in the pulling direction. During this displacement, the force storage device 8 of the automatic retracting device 4 is tensioned by the actuator 5, specifically, the tension is applied by the control protrusion 6 and the driving device 7 of the actuator 5. When the traveling rail 3 exceeds a predetermined pull-out path, the drive device 7 is tilted by being guided accordingly, deviated from the range of engagement with the actuator 5 and locked in this position. The running rail 3 can now be pulled out to the fully extended position and the automatic retracting device 4 remains in a position where the force storage device 8 is fully tensioned.

  Thereafter, when the running rail 3 is pushed back again in the closing direction, the control projection 6 reaches the range of the drive device 7 again at a certain displacement position, unlocks the drive device 7 and releases the force storage device 8. . As a result of the corresponding force, the traveling rail 3 is automatically pulled back in the closing direction by the interaction between the drive device 7 and the actuator 5.

  Since this method of operation and the function of the automatic retracting device 4 are generally known, a detailed depiction and description will not be necessary here.

  In particular, as shown in FIG. 4, the actuator 5 is fixed to the traveling rail 3 by a lock.

  For this purpose, the actuator 5 is equipped with two restraining hooks 9 provided with restraining projections 10 at the free end. A restraining protrusion 9 extends through the side wall 3a of the running rail 3, and one restraining hook 9 extends through the closing stopper 11 in the region of the opening 11a. The restraining protrusion 10 reaches the back of the web 11 b at the rear end of the closing stopper 11.

  The closing stopper 11 may be provided with two openings 11a through which the restraining hook 9 extends. In that case, the restraining protrusion 10 reaches behind the web 11b located between the two openings 11a.

  Further, as clearly shown in FIG. 4 in connection with FIG. 6, the restraining hook 9 is molded on the rectangular base 12 of the actuator 5. When these bases 12 project into openings 13 of corresponding dimensions in the side walls 3a of the running rail 3 and the actuator 5 reaches the periphery of the web 11b of the closing stopper 11 by the restraining hooks 9 and the restraining projections 10, the actuator 5 To stabilize the position.

  The actuator 5 as a whole is composed of one piece as a plastic part, and preferably is composed of one piece as a part by plastic injection molding. The same applies to the closing stopper 11, so that the actuator 5 and the closing stopper 11 can be manufactured with relatively small tolerances with respect to the fixing of the actuator 5 to the traveling rail 3, so that a very good positioning of the actuator 5 with respect to the traveling rail 3 is achieved. Can be achieved.

  As shown in FIGS. 4 and 5, both sides of the traveling rail 3 are arranged so that the actuator 5 can be easily attached to the left side or the right side of the traveling rail 3 depending on the mounting position of the automatic retracting device 4 to the guide rail 2. Is provided with an opening.

  Finally, since the closing stopper 11 is used decisively for fixing the actuator 5 to the traveling rail 3, no special means that may impair the production or manufacture of the traveling rail 3 other than providing the opening 13 is required. It is. In particular, it is not necessary to attach any parts to the running rail.

  As a result, the production of the running rail 3 and thus the production of the entire drawer guide 1 is generally greatly simplified and cheaper. In particular, the actuator 5 can still be attached to the traveling rail 3 even after the drawer guide 1 is completely manufactured.

  Since the drawer guide having the automatic retracting device and the drawer guide not having the automatic retracting device are manufactured in large quantities and are required in large quantities, the above-described configuration is an It has the advantage that it is not necessary to separate it from a drawer guide without an automatic retracting device.

  In particular, as shown in FIG. 6, the elasticity of the control protrusion 6 can be realized by making the control protrusion 6 relatively thin as compared with the area of the actuator 5 positioned in contact with the guide rail 3. Specifically, the control protrusion 6 can be elastically moved in a direction perpendicular to the connection surface between the traveling rail 3 and the actuator 5. This cannot be finally ruled out, and in the event of an incomplete operation in which the above-described interaction between the automatic retracting device 4 and the actuator 5 is canceled, the traveling rail 3 is once in this fully closed position. Returning to yields the advantage of automatically establishing the intended state. In this case, the control projections can deflect sideways and bounce back to the normal position in the fully closed position and again engage the drive device 7 of the automatic retracting device 4 in this process.

  Furthermore, the fact that the actuator 5 is made entirely of plastic material leads to a significant reduction in noise when the actuator 5 comes into contact with the drive device 7 of the automatic retracting device 4 again at the control projection 6.

  FIG. 7 shows a drawer guide 1 with an automatic retracting device 4 in which an actuator 5 for controlling the automatic retracting device 4 forms a subassembly together with a closing stopper 11a, the entire subassembly being The drawer guide 1 is attached to the traveling rail 3.

  In this case, the subassembly formed by the actuator 5 and the closing stopper 11a is preferably configured as a one-piece part, for example as shown particularly clearly in FIG. The fixing of the entire subassembly with respect to the running rail 3 is preferably effected in a meshing and / or friction manner. That is, for example, a region 11b of the closing stopper 11a that engages with the travel rail 3 can be provided with a restraining groove 11c that extends in a direction transverse to the longitudinal axis of the travel rail 3, and the subassembly can be attached to the travel rail 3. In order to fix it, the deterring device provided on the traveling rail 3 and penetrating inward by punching can be fitted into the deterring groove 10c. Naturally, for example, an opening is formed in the traveling rail 3, and a restraining protrusion or a restraining hook is formed in the region 11 b protruding to the traveling rail 3 in the closing stopper 11 a and is engaged with the opening of the traveling rail 3. Different types of connections are also possible.

  This includes, for those skilled in the art, any restraining connection suitable for ensuring that the subassembly consisting of the actuator 5 and the closing stopper 11a is fixed to the traveling rail 3 in the axial direction of the traveling rail 3.

  However, it is also possible to fix the closing stopper 11a to the traveling rail by pressing the traveling rail.

  This also has the advantage that simple and uncomplicated fixing of the actuator 5 to the running rail 3 is guaranteed. Furthermore, this embodiment also makes it possible to attach the actuator 5 to the running rail 3 of the drawer guide 1 afterwards.

  As already described, the subassembly composed of the actuator 5 and the closing stopper 11a can be configured as a one-piece component such as a component by injection molding.

  However, the individually manufactured actuator 5 and the individually manufactured closure stopper 11a are connected to each other by known connecting devices in a reliable manner, so that they form a fully prefabricated subassembly. Is also possible.

  Finally, FIG. 10 shows a restraining hook 14 (highly abstracted) fixedly connected to a drawer (not shown in detail) located on the upper side of the running rail 3 or manufactured in one piece with the drawer. It must be pointed out that it is only shown in the scheme. As shown very clearly in FIG. 10, this restraining hook 14 is provided on the subassembly of the actuator 5 / closure stopper 11a to secure the lift of the drawer after the drawer is placed on the running rail. Underneath the longitudinal web 15 can be reached.
