Description

The present invention relates to an ejection device for movable furniture parts, in particular drawers, with a feeder mechanism by means of which the movable furniture part can be brought into a closed position and durable, an ejection mechanism of an operable by a force storage ejector comprises the movable furniture part from a closed position to an open Position and a trigger mechanism that controls the loading and unloading of the energy storage.

There are electric discharge devices in which a switching pulse is generated by the user, so that then an ejector is moved by a motor and moves a movable furniture part, such as a drawer in the opening direction. The ejector can then be moved back to a starting position via a controller. The furniture part can then be moved during the closing process via a mechanical collection device in a closed position and held there. However, the arrangement of an electrically operated ejector is relatively complex, since when installing the furniture, an electrical wiring must be made and also consumed by the operation of energy.

It is therefore an object of the present invention to provide an ejection device for movable furniture parts, which avoids the disadvantages mentioned above and allows comfortable handling of the furniture, without the need for electrical energy to eject.

This object is achieved with an ejection device with the features of claim 1.

According to the invention, the ejection device comprises a force transmission unit, by means of which a force accumulator of the intake mechanism at least partially loads the energy accumulator of the ejection mechanism until it reaches the closed position. As a result, the method of the movable furniture part in the direction of the closing position can be adopted shortly before reaching the closed position of the feed mechanism, so that the user only has to move the movable furniture part in the closing direction over a part of the closing path to move the furniture part in the closed position. The closing position is defined by elastic stops that ensure the release path. The energy storage of the feeder mechanism is recharged during the ejection process. Due to the residual component of the retraction force accumulator of the retraction mechanism, it is not necessary that the furniture part is locked in the closed position, as is the case with conventional mechanical systems.

Preferably, a coupling is provided which interrupts the coupling of the feed mechanism with the ejection mechanism via a force transmission unit upon unlocking of the trigger mechanism. This can be operated by the retraction mechanism of the trigger mechanism after retraction of the furniture part in the closed position, so that then the energy storage of the ejection mechanism for movement of the mäbelteils in the opening direction, because the energy storage of the ejection mechanism has a greater force than the energy storage of the retraction mechanism, so that during decoupling of the ejector is active. The triggering path for triggering the trigger mechanism is ensured by moving the furniture part in the closing direction by elastic stops. When triggered in the closing direction of these attacks are compressed and activated the trigger mechanism. In the Schüeßrichtung, however, causes the power transmission unit that the power transmission is selected so that the energy storage of the feeder mechanism in its effective range due to the transmission ratio of the power transmission unit can clamp the energy storage of the ejection mechanism. As a result, in the closing direction of the energy accumulator of the ejection mechanism is at least partially loaded over a certain way, just before the closed position. According to one embodiment, the power transmission unit is designed as a lever mechanism. In this case, a lever may be provided which is movable on one side with the ejector and on the opposite side along a run-on slope. At the end of the lever to the starting slope, a roller can be arranged. The lever can cause a translation of the force ratios, that the lever arms are different lengths. The lever is preferably rotatably mounted on the movable furniture part or an associated component about a pivotable axis of rotation. For a decoupling of the lever mechanism may be formed at the end of the run-up slope, a rest position at which the roller remains. By a release movement of the furniture part, the roller can then be brought from the rest position, to then be spaced from the run-on slope to be moved when the furniture part moves in the opening direction. Through the different ways of the lever, a coupling is effected by the lever mechanism in the closing direction, while in the opening direction, the lever mechanism is disengaged.

According to a further embodiment, as power transmission unit wheels, in particular gears or friction wheels, provided, and a wheel is coupled to the ejector via a rack or a friction rod. As a result, a linear movement of the furniture part can be transmitted in a rotational movement of the wheels. The wheels are preferably non-rotatably connected and have a different diameter to provide a corresponding gear ratio. The wheels can be mounted on the movable furniture part or an associated component.

If rotatable wheels are used as power transmission unit, the clutch is preferably operated so that in a closing or opening release movement of the power transmission between the two wheels or a wheel and with the ejector or coupled to a furniture carcass rod is interrupted. Regardless of where the power transmission path is interrupted by the clutch, the power interruption ensures that the energy storage of the ejection mechanism performs an opening movement of the furniture part, while thereby the energy storage of the feed mechanism is loaded. By coupling in the closing direction, however, a retraction movement of the furniture part is obtained shortly before the closed position, since the energy storage of the feeder mechanism partially loads the energy storage of the ejection mechanism due to the power transmission.

The release mechanism preferably has a pin that can be coupled to the movable furniture part. The pin can be brought into engagement on a pivoting element, wherein during the pivoting of the pivoting element, the clutch is actuated. By pivoting the pivot member, a lever can actuate a clutch in the power transmission path between the stationary furniture body and the ejector.

According to a further embodiment, the housing of the ejection device is mounted on the guide rail of a pullout guide. About a shutter, the running rail of the pullout guide is ejected. The energy storage of the ejection device is preferably designed as a tension spring. The trigger is used on the tension spring to the housing of the ejector, while he pushes the running rail of the pullout guide. The decoupling of the power transmission unit can be carried out, for example, according to the mechanisms described above.

For the synchronization of two or more provided on a movable furniture part ejection devices, it is sufficient to press at least one ejection device by pressing or pulling. The energy storage of this ejection device causes the triggering of further ejection devices via the movable furniture part.

The triggering process can be triggered mechanically and / or electrically. Thus, at most a small electrical energy is needed to allow the triggering of the ejection devices. Electromechanical triggering device can also be used to synchronize and / or lock a plurality of ejection devices according to the invention.

a force-displacement diagram for an ejection device according to the invention.

An ejection device 74 for furniture is arranged for example on a furniture body 1, on which a movable drawer 2 is movable via a pullout guide 3. On the furniture body 1, an elastic stop 4 is provided, so that a closed position is defined in which a front panel spaced of the furniture body, for example, in the range between 1 and 4 mm, is arranged. The elastic stop may alternatively also be arranged between guide rail and running rail and / or middle profile and running rail of the pull-out guide.

On the pullout guide 3, a self-closing mechanism 73 is provided, which is effective from a range of for example 4 cm before the closed position and ensures that the furniture part 2 is moved into the closed position and held there. The self-retraction may also include a damper to reduce the speed of travel and to avoid "over-pressure", a direct release of the ejector,

The ejection device comprises a block 5 mounted on the furniture body 1 or a component connected thereto, on which a run-on slope 6 is formed. At the end of the run-on slope 6, a rest position 7 for holding a roller 10 is provided. The roller 10 is mounted at the end on a lever 8, which is connected on the opposite side via a hinge 11 with an ejector 13. The lever 8 is rotatably mounted about an axis 9 on a housing 12 which is fixed to the furniture part 2. The axis 9 is arranged off-center, for example in a ratio of 2/3 to 1/3, to make a corresponding power transmission. Furthermore, the axis 9 is held on one side in a pivot bearing on the housing 12. The pivoting of the axle 9 allows the lever 8 to descend the height differences of the run-on slope 6. A spring 19, preferably designed as a tension spring, brings the remote role 10 with her paragraph when engaging with the run-on slope 6 to the system and disengaged from the run-on slope 6 in the release position (decoupling).

The ejector 13 is in the closed position on a surface 16 of the rear wall of the furniture body 1, wherein at the end of the ejector 13, a cap 15 is arranged. Alternatively, the ejector can also rest on another relative to the movable furniture part stationary component. On the cap 15, one end of a spring 14 is supported, which rests on the opposite side to a contact surface of the housing 12.

By releasing the roller 10 from the rest position 7, the lever 8 can pivot freely about the axis 9, wherein the roller 10 spaced from the run-on slope 6 can be moved freely. As a result, the spring 14 of the ejector 13 and can thus repel the drawer 2 of the surface 16 of the rear wall. The ejector 13 is guided on the housing 12 so that it remains largely aligned in the opening direction. When the cap 15 loses contact with the surface 16 of the rear wall, the drawer can be moved freely.

For a closing movement of the drawer 2 is first moved into the furniture body 1 until the roller 10 engages the run-on slope 6 in engagement and the spring 14 is tensioned. In FIG. 2 For example, a position of the ejector 74 during the closing operation is shown. The lever 8 is arranged so that the roller 10 is moved along the run-on slope 6 and thereby the spring 14 of the ejector 13 is compressed. The contact angle alpha between the run-up slope 6 and the lever 8 is less than 90 °. When the self-closing mechanism 73 engages shortly before the closing position, the self-closing mechanism 73 now begins to move the drawer 2 into the closed position, the lower force of the self-closing spring being sufficient to move the spring 14 due to the transmission ratio of the lever 8 acting as a force transmission of the ejector 13 to tension.

In the FIGS. 3A and 3B the lever 8 and the roller 10 are shown in detail. The roller 10 is stepped and includes an upper disc-shaped portion having a larger diameter than a lower disc-shaped portion. If the role 10 is appropriate FIG. 4 is moved to the run-on slope 6, thereby the roller 10 can be moved not only in the direction of the rear wall of the furniture body 1, but is additionally moved against the force of a spring 19 or the weight up. For this purpose, an upwardly running ramp 17 is formed on the run-on slope 6, which has a flat transition 18 adjacent to the rest position 7 at the end. The rest position 7 is formed by a web on which the roller 10 rests as long as the furniture part 2 remains in the closed position. A trigger mechanism can be unlocked by pulling or pressing on the furniture part 2, to then open the furniture part 2. Then, the roller 10 slides down and can move at a distance from the run-on slope 6, so that the ejector 13 causes an opening movement against the force of the spring of Selbsteinzuges 73.

In FIG. 5 a modified embodiment of an ejector 74 'is shown, wherein the same components are provided with the same reference numerals as in the previous embodiment. A drawer 2 is at one Pull-out guide 3 movably mounted, wherein on a stationary guide rail or on the furniture body 1 in the axial direction on a spring 33 movable pin 26 and a rack 25 are arranged. A control element 39 comprises the pin 26, which can be moved in the axial direction on the spring 33, and a base element 32. The spring 33, preferably designed as a compression spring, acts between the base element 32 and the pin 26. The control element 39 is designed in the sense of a fork, in which the pin 26 and the base member 32 each form a prong. The rack 25 is engaged with a first gear 24 rotatably connected to a second gear 22 of smaller diameter than the gear 24 is connected. The smaller gear 22 is in engagement with a rack 21 which is connected end to an ejector 13, which in turn is biased by a spring 14 in the opening direction, wherein the spring 14 is supported on a housing 20, and on the opposite side to a Cap 15 rests, which is supported on the surface 16 of the furniture body. On an axis 23, the gears 22 and 24 are mounted.

In a movement of the drawer 2 in the closing direction, the spring 14 of the ejector 13 is tensioned in an engagement of the larger gear 24 with the rack 25, wherein initially a manual clamping by the user is necessary. Shortly before reaching the closed position, the spring of Selbsteinzuges 73 is now effective on the pullout guide 3, wherein due to the translation through the different diameters of the gears 22 and 24, the spring of Selbsteinzuges 73 biases the spring 14 of the ejector 13 and the drawer 2 so in moves the closed position.

To decouple the transmission, a rod 30 is provided, which is connected on one side about an axis 31 rotatably connected to the rack 21 and is connected on the opposite side about an axis 28 with a pivot member 27. The pivoting element 27 comprises a receptacle 36 for the pin 26. The pivoting element 27 is mounted on an axis 29 on a housing 20.

In the FIGS. 6A to 6C is the ejector of the FIG. 5 shown schematically, wherein the length ratios of the rod 30 have been shortened for a better clarity. During the closing movement, the rack 21, which is coupled to the movable furniture part 2, moved in the furniture body in the closing direction X, while the pin 26 stationary on the furniture body 1 or the Guide rail of a pullout guide 3 is fixed. It is of course also possible to form the locking mechanism vice versa, so the pivot member 27 stationary and the pin 26 to form movable.

During the closing movement, the pin 26 is inserted into a receptacle 36 of the pivoting element 27. For this purpose, the pin 26 is spring-mounted by means of a spring 33 on a base element 32 of the control 39 so as to be compressible, the base element 32 being movable along a run-on slope 34. The run-on slope 34 is coupled to the movable furniture part 2.

As in FIG. 6B is shown, the base member 32 of the control element 39 moves along the run-up slope 34 upwards, so that the spring 33 is compressed and the pin 26 now rests against the underside of the pivoting element 27. By a further method of the furniture part 2 in the closing direction X now an end portion 35 is reached at the run-on slope 34 which is disposed below the receptacle 36 of the pivoting element 27. This allows the pin 26 einliegen by the force of the spring 33 in the receptacle 36 ( FIG. 6C ). In this position ( FIG. 6C ), the furniture part 2 is held in the closed position.

For an opening movement can according to the FIG. 7B the furniture part 2 are first pressed in the closing direction X. Then the in FIG. 7B achieved position, at the same time the pivot member 27 is rotated due to the force of the pin 26, wherein the pivot member 27 is rotatably mounted about an axis 29 on the housing 20. As a result, the pivot member 27 rotates about the axis 29 and thereby moves the lever 30, so that the rack 21 is lifted from the gear 22.

The pin 26 is released by pushing the drawer, because the base member 32 from the end 35 of the run-on slope 34 leaves the end portion and thereby the base member 32 can move down again and the pin 26 is moved out of the receptacle 36 ( FIG. 7B ). Subsequently, the pin 26 'together with the relaxed base element 32' of the control element 39 and the spring 33 can be moved past the run-on slope 34 in the opening direction Y ( FIG. 7C ). This is made possible because the relaxed control element 39 can bypass the run-on slope 34 in the opening direction Y, after which the control element 39 passes through a double-sided ramp 37. The double-sided ramp 37 ensures the subsequent closing operation Moving up the control element 39 on the run-on slope 34 and thus prevents a malfunction. By decoupling the rack 21 from the gear 22, the power flow of the transmission is interrupted by the gears 22 and 24, so that the ejector 13 can move the drawer 2 in the opening direction.

In the FIGS. 8A to 8C an unlocking of the locking mechanism by pulling on the drawer 2 is shown. In Figure 8A the closing position Z is shown, at which the pin 26 is located in the receptacle 36 of the pivoting element 27. By pulling on the drawer 2, the pivot member 27 is rotated about the axis 29, so that the lever 30 lifts the rack 21 from the gear 22 due to the articulation on the axis 28 and 31. The axis 29 is arranged between the axis 28 and the axis 31, so that the pivoting movement of the pivot member 27 by means of the linear movement of the rod 30, the rack 21 separates from the gear 22. After the pivoting of the pivoting element 27, this can be moved back into the central starting position due to the force of a spring, not shown ( FIG. 8C ), while the pin 26 is decoupled from the pivot member 27 and thereby the drawer 2 can be moved in the opening direction Y.

In the Figures 9A and 9B Fig. 12 shows a further embodiment of a triggering mechanism of an ejection device, wherein only the gearbox and the triggering mechanism are shown. The transmission includes gears 22 and 24, which mesh with racks 21 and 25 as in the previous embodiment. The gears 22 and 24 are rotatably connected to each other via a coupling, for example, a dog clutch having a first coupling part 40 and a second coupling part 41. On the coupling part 41, projections 42 are formed, which are in engagement with corresponding recesses on the coupling part 40. By moving the toothed disc 24 in the axial direction, the coupling parts 40 and 41 can be disengaged to interrupt the path of the power transmission.

For this purpose, a trigger mechanism is provided, which comprises a pivot member 49, a pin 50 of a control element 59 and a rod 45, similar to the previous embodiment. The rod 45 is rotatably mounted at one end via an axis 48 on the pivot member 49 and at the opposite end via an axis 46 at a block 44. The pivoting element 49 is mounted about an axis 47 on a housing 58, so that by pivoting the pivot member 49, the rod 45 in FIG. 9B is moved to the right. At the block 44, a starting bevel 43 is formed on the underside, which rests against the gear 24 on a slip ring 54. If the linearly guided block 44 is moved to the right via the rod 45, the toothed wheel 24 lifts the lower coupling part 41 away from the upper coupling part 40 and thus ensures a decoupling between the two toothed wheels 22 and 24. The toothed wheel 24 is acted upon by an axially acting spring 53, for example, a plate spring, pressed against the gear 22. When decoupling the force of the spring 53 must be overcome. Incidentally, the triggering mechanism is formed as in the previous embodiment.

In the Figures 10A and 10B a modified embodiment of the last embodiment is shown, wherein between the gears 22 and 24 another coupling is provided. A rod 55 engages with a tip 56 directly into a coupling portion 57 to move the upper gear 22 up and the lower gear 24 down and decouple the two gears 22 and 24 from each other. The rod 55 is mounted via an axle 48 on a pivoting element 49 which is mounted on a housing 47 via an axle 47. On the pivot member 49, a pin 50 is mounted, which is connected via a spring 52 with a base member 51 and, as in the FIGS. 6 to 8 shown can be introduced.

A reversal of the arrangement according to FIG. 5 show the Figures 11A and 11 B. According to a further embodiment, the housing of the ejection device 74 "is mounted on the guide rail 61 of a pullout guide 3 'The guide rail 63 of the pullout guide 3' is ejected via a trigger 13 ' educated. The trigger 13 'is applied to the housing 66 of the ejection device 74 "via the spring 65, thereby pushing on the running rail 63 of the pullout guide 3' The decoupling of the force transmission unit in the form of a transmission 64 can be effected, for example, according to the mechanisms described above Pull-out guide 3 'includes a guide rail 61, an optional Mittelprofiil 62 and a running rail 63. The ejector 74 "is set on its housing 66 on the guide rail 61 of the pullout guide 3'. A rack 25 is fixed to load the spring 65 on the running rail 63. Furthermore, the pullout guide 3 'with a from the state of Technik known feeding mechanism equipped, which is not shown in the schematic figures. The functionality corresponds largely to that from the FIG. 5 known embodiment. The Figure 11A shows the rest position Z of the ejection device 74 "or the pullout guide 3 ' FIG. 11B shows the opening operation after the actuation of the triggering device and the activation of the ejector 74 ".

In FIG. 12 a force-displacement diagram of an ejection device according to the invention is shown. The zero point on the abscissa is the closed position of the movable furniture part. The upper curve 70 shows the force curve of the spring 14 when ejecting the drawer 2 in the opening direction. The spring 14 is effective over a longer distance than the spring of the retraction device 73. The spring of the retraction device 73 shows a force curve is shown in the curve 71. The spring of the intake device is effective at the point 72, ie just before the closed position.

In the illustrated embodiment, the ejection device has been described for a movable furniture part, which is designed as a drawer. It is of course possible to use the ejector also for sliding doors, hinges or other movable furniture parts. In addition, the release mechanism and / or the power transmission unit can be modified within wide ranges.
