Description

Accelerator for movable furniture or household appliances

The present invention relates to an acceleration device for a movable furniture or household appliance part as described in the foregoing paragraph 1 of the patent application, the movable furniture or household appliance part being in particular a drawer or a door.

An opening device for a movable furniture part is known from the prior art (for example, EP 7 669 393 A1), in which the movable furniture part is accelerated and pushed out in the opening direction by means of the push-out mechanism, the movable furniture part (for example a drawer) is first held in the closed position. And unlocking the opening device by pulling or pressing in a reverse direction, in which the movable furniture portion leaves the furniture body.

The spring tensioning system for accelerating the movable furniture portion on such an opening or closing device has a generally linear spring constant and is tensioned during continuous motion, such as when the movable furniture portion is pushed back to its closed position within the furniture body. .

A disadvantage of the prior art opening or closing device is that, particularly when the construction space is limited, one side is provided with a short, high-strength spring which is applied to the movable furniture portion when it is tensioned and untensioned. The difference in force is extremely large (ΔF high), and if the user suddenly interrupts the operating force after the spring is tensioned, it will have an adverse effect. Among them, if an additional folding system is not provided, a spring with a low spring constant cannot usually be used.

Another disadvantage of the prior art systems is that when the tensioning process is interrupted At this time, the energy that has been absorbed by the spring will be re-released in the reverse direction of movement, causing the portion of the furniture to be opened or closed to return to the initial position, thereby causing the user to be injured in the worst case.

In order to avoid the above-mentioned situation, for example, DE 102 46 438 A1 discloses a drawer system comprising an automatic pull-in device and a manually detachable holding system which enables the drawer to remain open at different positions against the spring force. The disadvantage is that the user needs to manually unlock, that is, the user needs to extend his hand under the drawer when unlocking.

It is an object of the present invention to provide an acceleration device for a movable furniture portion, that is, a device for supporting or implementing an opening and/or closing process in a positive or negative acceleration manner, wherein at least one force is coupled to the coupling of the acceleration device The reservoir can be interrupted in a harmless manner and the acceleration device is easy to operate.

The solution for achieving this object of the present invention is an acceleration device for a movable furniture portion having the features of claim 1 of the patent application.

The acceleration device of the present invention comprises a folding device mounted to a housing of the push-out or pull-in device, through which the force storage device is coupled to the coupling, the folding device being coupled to a locking device by which the locking device is coupled The device can secure the force reservoir to at least an intermediate position between the minimum tension position and the maximum tension position during tensioning.

In this way, for example, when the ejection device pushes, for example, the drawer into the furniture body again, the force storage device is tensioned and held in the intermediate position when a weak thrust is applied to the drawer in the direction of the closed position of the drawer and cannot reach the closed position. Thereby the drawer directly or indirectly coupled thereto is only partially, ie not completely pushed out of the furniture body again. This effectively prevents the force reservoir from being completely unloaded before the tensioning process is completed.

Advantageous embodiments of the invention are the subject of the description of the subsidiary.

According to an advantageous embodiment of the invention, the folding device has a running curve that changes the distance of the hinge point of the force reservoir to the axis of rotation of the folding device during tensioning or relaxation. The folding device specifically has a wheel-shaped body rotatable about a rotation axis, and the connecting member connected to the body of the coupling and the folding device can be wound around the peripheral side of the body oriented parallel to the rotation axis when the body rotates. On the edge, the coupler is connected through the connecting element and the folding device.

By changing the distance from the point of application of the reservoir to the point of rotation of the folding device, a torque change is caused, which has a beneficial effect on the ease of use of the movable furniture portion during tensioning, since it is no longer felt at this time. The interruption of the maneuvering force to the foregoing, or at least greatly reduced, does not change the system's required closing or opening force.

According to another aspect of the present invention, the body of the folding device has a groove extending radially toward the rotation axis, and a coupler extending parallel to the rotation axis of the folding device is guided in the groove, The coupler can be guided in a control curve formed on the housing and/or the cover surrounding the housing. Wherein, the control curve preferably has at least one locking position defining an intermediate position between the minimum tensioning position of the power storage and the maximum tensioning position.

By combining such a folding device with a control curve, the locking position can be formed in a simple manner, and the force reservoir, preferably configured as a tension spring, can be held in the locked position during its tensioning process. It is only necessary to completely close or open the movable furniture portion by further pressing or pulling the movable furniture portion into its end position without manually releasing the lock.

The invention will be described in detail by way of examples with reference to the accompanying drawings.

Show and location. These terms should not be construed as limiting, that is, The situation can be changed by changing the station or using a mirror symmetrical design or taking similar measures.

In Fig. 1, the acceleration device for the movable furniture portion of the present invention is constructed such that the embodiment of the ejection device is generally indicated by the reference numeral 1.

In the further description, the acceleration device will be described by taking the illustrated ejection device as an example, in which the force storage device 4 is tensioned during the closing of the movable furniture portion, for example, the movable furniture portion is, for example, relatively A moving element that moves the furniture body, such as a drawer, sliding door, or swing door. However, the use of such an acceleration device, such as a pull-in device that is intended to support the closing process of a movable furniture or household appliance portion, or support for the opening and/or closing of a sliding door or a swing door fixed to a hinge, may also be provided. .

The ejection device 1 shown in Fig. 1 has a housing 2 and a cover 3 for closing the housing 2. As shown in the exploded view of FIG. 1, the housing 2 is provided with a plurality of first guiding routes 25 and second guiding routes 26 extending in parallel with each other.

The coupling 13 is guided in a first guiding path 25, which can be latched in a conventional manner in a first end position, in which the movable furniture part which can be pushed out by the coupling 13 is in its closed position . The coupling 13 is inclined at this end into the curved end section of the first guiding path 25.

A lever 8 rotatably mounted to the housing 2 is used to raise the coupling 13 away from the position of the curved section that is inclined into the first guiding path 25, thereby triggering the ejection process, protruding from the housing 2 The carriage 15 is movable in the second guiding path 26 and urges the movable furniture portion to be pushed out through the operated lifter 16 fixed to the carriage 15, and when the carriage moves, the direction R is reversed through the carriage 15 Sliding downwardly presses one of the force arms of the lever 8 such that the other force arm of the lever 8 catches the coupler 13 for guiding the coupler 13 in the first guiding path 25 and Engaged under the pin of the guiding path 25, thereby lifting the coupler 13 away from the curved end section of the first guiding path 25 and into the area of the first guiding path 25 parallel to the second guiding path 26. .

By lifting the coupler 13 into the region of the first guiding path 25 parallel to the second guiding path 26, the tip of the coupler 13 catches behind the stop of the carriage 15 and along the pushing direction with the carriage 15 snaps.

Further, as shown in FIG. 1 and FIG. 2, the coupler 13 is connected to the power storage device 4, which is preferably configured as a tension spring, through the second connecting member 9, the folding device 10 and the first connecting member 5, wherein When the position of the device 13 is positioned within the curved section of the first guiding path 25, the power reservoir 4 is in the maximum tension state as shown in FIG. The second connecting element 9 is preferably a tie rod or a cord, the first end 23 of which is fixed to the coupling 13 and the second end 24 is fixed to the recess 12 of the body 28 of the folding device 10. The second connecting element 9 can also be constructed as a rigid element, for example a toothed rack.

Correspondingly, the first connecting element 5 is fixed at its one end to the force reservoir 4 which is embodied here as a tension spring, and at its other end to the body 28 of the folding device 10. Depending on the specific design of the force reservoir 4, the force reservoir 4 can also be directly connected to the folding device 10.

As shown in Figure 1, the folding device 10 is generally comprised of a partially wheeled body 28 that includes recesses 12 extending radially inwardly from the periphery for receiving the second connecting member. One of the ends 24 of the 9 and in particular one of the ends of the first connecting element 5 of the rope or tie rod.

In the particular embodiment shown here, the folding device 10 is rotatably mounted to the housing 2 and the cover 3, wherein the distance from the hinge point of the force reservoir 4 to the axis of rotation 23 of the folding device 10 has Turns the travel curve that changes during the process.

The peripheral side edge 27 of the body 28, which is oriented parallel to the axis of rotation 23, is here for receiving a connecting element 9 which is connected to the coupling 13 and which can be wound on the peripheral side edge 27 when the body 28 is rotated.

A section of the edge 27 of the wheel body 28 has a channel 11 extending in the direction of the fold within a predetermined angular extent of the body 28, in which a segment of the force reservoir 4 or with the force reservoir 4 The first connecting element 5 , which is connected to the body 28 , is pressed radially closer to the axis of rotation 23 of the folding device in the region of the predetermined rotational angle of the folding device 10 . Thereby, the rotation acting on the folding device 10 can be reduced by changing the point of application of the force applied to the folding device 10 by the force reservoir 4 configured as a tension spring when approaching the closed position of the coupler 13. Moment, thereby preventing a sudden interruption of the operating force when the ejection device is tensioned.

As shown in FIG. 1, FIG. 2 and FIG. 4, in the region of the folding device 10 on the casing 2, a control curve 20 is provided on the casing 2 and/or the cover 3 toward the inside of the casing 2, along the edge. The guided actuator 18, which is guided radially toward the axis of rotation 31 of the body 28, is guided in the control curve so that when the folding device 10 is rotated, the coupling 18 is concave in the body 28. The radial movement in the groove 19 is guided in the control curve 20. Wherein, the control curve 20 has at least one locking position defining an intermediate position between the minimum tensioning position of the force storage 4 and the maximum tensioning position. In the illustrated embodiment, the control curve 20 has a first locking position 21 and a second locking position 22.

In an alternative embodiment, the coupler 18 that can be guided in the control curve 20 is configured to be snap-fit or clamped in the control curve 20 when the body 28 is moved in the reverse direction of the tensioning direction.

Referring to FIG. 2 to FIG. 18, the pushing process of the pushing device 1 and the subsequent The push process is explained. As previously mentioned, Figure 2 shows the initial position of the ejection device in which the actuator 13 is located in the curved region of the first guiding path 25 and engages with the carriage 15. The force reservoir 4 is in the maximum tension state at this position.

After the carriage guide 15 is moved backwards in the reverse direction to successfully trigger the ejection process and the linkage 13 is moved away from the curved region of the first guide route 25 into the region of the first guide route 25 parallel to the second guide route 26 Referring to FIG. 5, the coupling 13 is pulled through the connecting member 9 and the folding device 10 by the force storage device 4 connected to the folding device through the connecting member 5, and is pushed in the pushing direction X in the process. The carriage 15 in the guide path 26 is guided until the coupler 13 and the carriage 15 respectively reach the other end of the corresponding guide path 25, 26 and the force reservoir 4 is fed into the maximum possible slack position during this process. This position is shown in FIG.

7 to 11 show intermediate positions, in particular in which the connecting element 5 is guided in the slot 11 of the body 28 at the beginning of the pushing-out movement, whereby the application to the folding device 10 is effected. The torque is lower due to the smaller distance from the point of application to the axis of rotation 31 and leaves the slot 11 in a clockwise direction as the folding device 10 rotates and abuts against the periphery 27 of the body 28, the circumference being designed according to its shape, The outer diameter of the self-rotating shaft 23 is moved outward at a larger twist angle, so that the linker 13 is pulled into the end position with maximum torque immediately before the end of the push-out of the carriage 15 or the coupler 13.

As shown in FIGS. 8 and 10, during the push-out process, the actuator 18 is initially guided along a predetermined path in the control curve 20 on a route region where the control curve 20 is coaxial with the rotary shaft 31, and is over a predetermined angle. The movement is shifted toward the rotating shaft 31 (see Fig. 10).

During the push-in motion of the carriage 15 or the coupler 13 to return to the initial position shown in FIG. 2, the coupler 13 is rotatably fixed to the carriage 15 in a deflectable manner as shown in FIGS. 13 to 18. The support member 14 is pushed back to the initial position as shown in FIG. Power reserve 4 at this time Tightening again. As long as the carriage 15 interrupts the urging force during the tensioning process, the coupler 18 enters the first lock shown in FIG. 14 according to the current position of the coupler during the radial inner route from the head to the end of the control curve 20. The position 21 or the second locking position 22 as shown in Fig. 15 prevents the coupler 13 from springing back under the tension of the force reservoir 4. Thus, by moving the carriage 15 further against the ejection device, the closing motion intercepted by the first or second locking positions 21, 22 can be continued until the end position of the coupler shown in Fig. 17 is reached.

As shown in FIGS. 18 and 19, the strength accumulator 4 is fixed to the housing 2 of the pull-out device 1 by a force reservoir holder 6. The force reservoir holder 6 has an adjustment element 7 which is preferably embodied as an adjustment screw, with which the individual adjustment can be effected by moving the force reservoir holder 6 in the direction of the push X or counter to the direction of the push. Prestressing of the force reservoir 4. 8 shows the position of the force reservoir holder 6, in which the force reservoir 4 configured as a tension spring is in a slightly tensioned state, and the force reservoir holder 6 is shown in FIG. In position, the force reservoir 4 is in a strongly pretensioned state.

In order to compensate for the tolerance when the triggering stroke of the ejection device is preset, the housing 2 is further provided with an adjustment wheel 29, which is preferably provided with an eccentric support edge 30 which abuts the lever away from the coupling 13 The bottom surface, with which the lever 8 can be adjusted into a predetermined initial position, whereby the stroke of the lever 8 can be adjusted by visually adjusting the position of the wheel. 20 and 6 show different adjustment situations of the adjustment wheel 29.

The main point is that, when the drawer is closed by the above-mentioned ejection device 1, if the actuator 13 is pushed to push the drawer to be closed with too small thrust, the locking device intercepts the tension of the force storage device acting on the coupling in at least one intermediate position, so that only one A small amount of tension is directed back to the guiding system. As a result, the drawer will be pushed back towards the user at a much smaller speed, in which case, The drawer can be completely closed by simply pressing it again without having to manually unlock it.
