Abstract

Device for moving a movable furniture part, wherein the device comprises guide means which connect the movable furniture part with a furniture body of a furniture movable. The device is characterized in that an ejector unit is arranged on the device in order to move the movable furniture part from a closed position on the furniture body to an open position after a triggering of the ejector unit.

Description

The invention relates to a device for moving a movable furniture part, as well as a piece of furniture with such a device.

State of the art

Devices of the type described in the introduction are known, for example, in the form of flap fittings for wall units. In a known device, an ejector unit is formed separately from the flap fitting. For example, the ejector unit and the flap fitting are disposed on opposite side portions of a front of the upper cabinet. The flap fitting and the ejector unit are thus separated from each other in two steps by a fitter attached to the wall unit.

Purpose and advantages of the invention

The invention is based on the object to provide an improved device for ejecting a movable furniture part relative to a furniture body.

This object is solved by the features of claims 1, 2 and 14.

In the dependent claims advantageous and expedient embodiments of the invention are given.

The invention relates to a device for moving a movable furniture part, wherein the device comprises guide means which connect the movable furniture part with a furniture body of a furniture movable.

The movable furniture part is e.g. a furniture door or a furniture flap and is connected via the guide means of the device so movable with the furniture body of the furniture, that it can be moved, for example, by a force of a user from the outside from a closed position on the furniture body in an open position. The guide means are for example designed as flap fitting or hinge and comprise e.g. a four-jointed joint.

The essential aspect of the invention is now to be seen in the fact that an ejector unit is arranged on the device in order to move the movable furniture part from the closed position on the furniture body into the open position after a triggering of the ejector unit.

Arranging the ejector unit on the device is understood to mean that the ejector unit is part of the device. As a result, assembly of the device with the ejector unit is simplified because the ejector unit is mounted together with the device.

Advantageously, the movable furniture part is moved from the closed position on the furniture body by the ejector unit in the open position on the furniture body, in particular ejected, so that the movable furniture part at least in a partially open state on Moving furniture body that a user can engage behind the movable furniture part. As a result, a user can move the movable furniture part from the partly open state to a completely open state on the furniture body.

The ejector unit is advantageously a mechanical component. For example, the ejector unit is designed as an automatic opening.

It is also conceivable that the ejector unit does not drive the movable furniture part over its entire opening movement or is drivingly connected to the movable furniture part.

In an advantageous embodiment of the invention switching means are provided on the device to change a function of an ejector unit.

In the variant of the device with switching means according to the invention, it is advantageous if the ejector unit is likewise arranged on the device. The switching means and the ejector unit can thus be regarded as part of the device.

It is further proposed that the switching means are provided to switch the ejector unit on or off.

By means of the switching means, it is for example possible to deactivate the ejector unit, thereby allowing a user without the support of the ejector unit to move the movable furniture part from the closed state to an open state on the furniture carcass.

When the ejector unit is activated by the switching means, the ejector unit can support an opening movement of the movable furniture part, advantageously at least in a partial area of a movement area of the movable furniture part. The ejector unit moves the movable furniture part, for example automatically in an open position on the furniture body.

For example, the switching means can switch the ejector unit on or off by a movement.

Advantageously, the ejector unit is switched on or off by a movement of the switching means, in particular by a rotational movement of a switching means.

It is also advantageous that the ejector unit acts directly on a movable element of the guide means of the device.

Advantageously, the ejector unit is advantageously connected directly to a movable element of the guide means and drives it, for example with one arm of the four-bar linkage. In particular, the ejector unit couples directly with a hinge mechanism and / or a lever arm of the fitting.

This results in e.g. Friction losses and / or comparatively large movements of the ejector unit avoided, since leverage effects are preferably used by the arrangement of the ejector unit on a movable element of the guide means.

Moreover, it is advantageous that the ejector unit is arranged on an arm of the guide means.

As a result, an assembly of the ejector unit is simplified. For example, the ejector unit is already arranged in the factory on the hinge, advantageously integrated into a hinge arm. Thus, an installer only needs to mount the hinge to install the hinge and eject mechanism for the movable furniture part on the furniture.

If the device is designed as a hinge can be present in addition to the hinge arm a hinge cup, which hinged to the hinge arm is connected. It is conceivable that the ejector unit is formed on the hinge cup, or by separate components on both the hinge arm and the hinge cup. For example, the hinge is arranged on its hinge arm on the furniture body and his hinge cup on the movable furniture part, or vice versa.

Moreover, it is advantageous that the ejector unit is accommodated in the guide means of the device.

For example, the ejector unit is arranged on the hinge or housed in the hinge so that it is not visible to a user from the outside.

Advantageously, the ejection unit is placed in the arm of the guide means e.g. installed the fitting arm, thereby the ejector unit is not visible to a user inside the guide means e.g. hidden from the fitting arm.

Furthermore, it is preferred that the ejector unit comprises a force accumulator.

The ejection unit and / or the energy accumulator of the ejector unit can be triggered by a movement, e.g. the movable furniture part, in particular by a pressure of a user from the outside in the closing direction on the movable furniture part, which is in the closed state on the furniture body. If the ejector unit or the energy accumulator triggered, the energy storage moves the movable furniture part advantageously via a movement of the guide means, z.b. the hinge mechanism of the hinge, from a closed position to an open position on the furniture body.

Advantageously, the switching means are designed in such a way, in the switched-off state of the ejector unit, to fix the force accumulator and thus to deactivate it. For example, the switching means comprise a latch component, which firmly locked in the activated state of the switching means with the energy storage or a part of the energy storage and thereby deactivated the energy storage.

It is also advantageous that the energy accumulator is designed as a spring element.

Advantageously, the spring element is in the closed state of the guide means or the movable furniture part under a bias. If the spring element is triggered, it can relax and thus carry out and / or assist an opening movement of the movable furniture part via or through the guide means.

Moreover, it is advantageous that the ejector unit is designed such that it dampens a closing operation of the movable furniture part.

For example, the ejector unit, in particular the energy accumulator, absorbs kinetic energy of a closing movement of the movable furniture part.

For example, an ejection mechanism of the ejector unit is loaded during the closing operation of the movable furniture part. Advantageously, the energy storage device is brought into an activated state during the closing process. Advantageously, the spring element is set in a prestressed state.

The device may also include a separate from the ejector unit damping element which absorbs a kinetic energy of a closing movement of the movable furniture part.

In an advantageous modification of the invention, the ejector unit has a receiving member and the force accumulator is movably guided by the receiving member.

For example, the spring element is a helical spring executed and movably mounted on a rod-shaped and / or wave-like receiving organ and movably guided.

Moreover, it is advantageous that the ejector unit has a transmission member which is movably guided by the receiving member.

Preferably, the transmission member is configured as a housing and inside the housing components of the ejector unit are housed, such as e.g. the energy storage, the switching means and / or parts of the receiving organ. As a result, the ejector unit is e.g. as a compact unit.

In an advantageous variant of the invention, the transmission member transmits a force or movement of the force accumulator to the guide means.

In a significant embodiment of the guide means, the receiving member is connected to a first end fixed to the guide means. Preferably, the receiving member to the guide means, such as the hinge arm, screwed, clamped and / or riveted. With a first end opposite the second end of the receiving member is movable, in particular slidably connected to the remaining components of the ejector unit, in particular with the force accumulator and the transmission member. For example, the energy storage device is fixedly arranged on the transfer element.

Furthermore, the transmission member is connected to a hinge mechanism of the guide means. As a result, the transmission member can transmit a force and / or movement of the energy accumulator to the joint mechanism of the guide means.

In an advantageous modification of the device, the ejector unit has a functionality of a touch-latch ejector unit.

Advantageously, it also proves that the device comprises a holding means which is designed to hold the ejector unit in the closed state of the movable furniture part on the furniture body in a loaded or activated state.

The holding unit comprises, for example, magnetic means which are arranged separately from one another on a front side of the furniture body and on an inside of the movable furniture part facing the front side of the furniture body. In the closed state of the movable furniture part on the furniture body, the magnetic means advantageously couple with each other and thereby hold the movable furniture part in the closed state on the furniture body.

In an advantageous variant of the invention, the device is arranged on a piece of furniture and the furniture comprises a holding member which is designed to hold the ejector unit in a closed or activated state in the closed state of the movable furniture part on the furniture body.

A hinge 1 according to the invention comprises a hinge arm 2 and a hinge cup 3. In FIG. 1 the hinge 1 is shown in a closed or folded state. In FIG. 2 is the hinge 1 with semitransparent Hinge arm 4 and semi-transparent hinge cup 3 shown. This allows a viewer of the FIG. 2 Look at the inner workings of the hinge 1.

The hinge arm 2 is connected to the hinge cup 3 via lever arms 5, 6, 7 of a lever mechanism of the hinge 1 pivotally or hingedly connected. Furthermore, an ejector unit 8 is formed in the hinge arm 2 in addition to the lever arms 5, 6, 7. The ejector unit 8 (FIG. FIG. 3 ) comprises inter alia a transmission member 9 and a receiving member 10, wherein the receiving member 10 is movably, in particular displaceably mounted on the transfer member 9. The ejector unit 8 is fixed to a first end 11 of the receiving member 10 via a screw 12, in particular fixed in position relative to the hinge arm 2, mounted on the hinge arm 2. The transmission member 9 is movably connected to the lever arm 5. As a result, the transmission member 9 moves during an opening movement of the hinge 1 relative to the receiving member 10 and the hinge arm 4.

The ejector unit 8 comprises in addition to the transmission member 9 and the receiving member 10, a coil spring 13, a holding element 14 and a switching element 15 (FIGS. FIG. 4 ).

The holding element 14 has a sleeve-like or cylindrical shape and has a mushroom-shaped or disc-shaped lid 16 at a first end. The lid 16 comprises an inner opening which is configured such that the holding element 14 is mounted on a first section 18 of a guide element 10a of the receiving element 10 can be guided movably. In addition, the outer radius of the lid 16, for example, approximately corresponds to the outer diameter of the coil spring 13. In the assembled state of the ejector 8, the holding member 14 is movably mounted on the guide member 10a of the receiving member 10 and can abut against a stop 20 of a second portion 19 of the guide member 10a.

Furthermore, the coil spring 13 is placed on the holding element 14 and abuts in the assembled and in particular in the charged state of the ejector unit 8 with a first end 21 on the mushroom-shaped cover 16 of the holding element 14. A first end opposite the second end arranged 22 of the coil spring 13 abuts against a stop in the housing 9a and / or is fixed, in particular fixed in position in a housing 9a of the transfer member 9, for example, clamped, glued and / or screwed (not shown). The coil spring 13 can thus be moved in the attached state on the housing 9a with its first end 21 relative to its second end 22, for example, be charged or discharged.

Both the transfer member 9 and the receiving member 10 consists e.g. from two components. The transmission member 9 comprises, for example, a housing 9a and a housing cover 9b which, in the assembled state of the ejector unit 8, engages with the housing 9a. The housing cover 9b is also designed such that the receiving member 10 is slidably mounted with its rod-shaped guide member 10a and a housing 17 of the switching element 15, in particular rotatable, can be mounted or plugged or clipped.

The receiving member 10 consists for example of the rod-shaped guide member 10a and a clip-like head 10b. The guide element 10a and the head 10b can advantageously be latched into one another, in particular during assembly with the housing cover 9b. It is also conceivable that they are bolted together and / or glued together. About the head 10b, the receiving member 10 is fixed in position and / or movably mounted on the hinge arm 2 and the hinge housing 4, for example via the screw 12 is mounted.

The switching element 15 comprises, in addition to the housing 17, a pawl element 23, which comprises a latching projection 24. The latching projection 24 is in the activated state of the switching element 15 at the ejector unit 8 provided to form a stop for the holding element 14 and the cover 16 of the holding element 14, whereby the coil spring 13 is held in a prestressed state independently of a movement of the hinge 1 ( FIGS. 8-10 ). An activation or deactivation of the switching element 15 can be done by a user from the outside, for example by means of a tool engagement. For this purpose, the user engages by means of the tool in a slot-like recess 25 on the housing 17 of the switching element 15 and rotates the housing 17 and thus the switching element 15 counterclockwise or counterclockwise, wherein the axis of rotation falls on a longitudinal axis of the switching element 15 and parallel to a movement direction of the coil spring 13 and / or a longitudinal axis of the receiving member 10 is aligned.

In the FIGS. 5 to 7 is a movement sequence of an ejection movement of the ejection unit 8 from a start position (FIG. FIG. 5 ) into an end position ( FIG. 7 ). In order for the ejector unit 8 to be able to perform an ejection movement, the helical spring 13 or the retaining element 14 must be freely movable relative to the switching element 15. For this purpose, the switching element 15 is offset by a rotational movement, away from the receiving member 10, in a deactivated state. If the ejector unit 8 is activated, for example by releasing a holding means, which is formed on the hinge 1 (not shown), then the loaded coil spring 13 pushes the transmission member 9 (in FIGS FIGS. 5 to 7 only the housing cover 9b is shown) from the starting position relative to the receiving member 10 via a central position ( FIG. 6 ) into the end position ( FIG. 7 ). In the end position, the coil spring 13 is relaxed. The housing cover 9b slides in this opening movement along the guide element 10a of the receiving member 10. The receiving member 10 remains fixed in position on the hinge 1 and, in particular, does not move relative to remaining parts of the ejector unit 8.

The in the FIGS. 5 to 7 shown ejector movement is transmitted via the connection of the transmission member 9 with the lever arm 5 on the lever mechanism of the hinge 1. The hinge 1 is thereby at least partially opened.

In the FIGS. 8 to 10 is a deactivation process of the coil springs 13 (FIG. FIGS. 8 and 9 ) and a subsequent opening movement of the ejector unit 8 without power assistance by the coil spring 13 ( FIG. 10 ).

In order to deactivate the ejector unit 8, the coil spring 13 is in the discharged state (end position, FIG. 7 ) or in the opened state of the ejection unit 8 or the hinge 1, the switching element 15 is rotated in an activated position in the direction of the receiving member 10 ( FIG. 8 ). As a result, the mushroom-shaped cover 16 of the retaining element 14 abut against the latching projection 24 of the pawl element 23. This happens because the hinge 1 is first closed. In this closing movement, the housing 9 and thus the switching element 15 and the coil spring 13 in the direction of the head 10 b of the receiving member 10 is pushed onto the receiving member 10. By the closing movement, the coil spring 13 is charged, this is independent of the state of the switching element 15th

In the closing movement, the pawl element 23 is pushed past the mushroom-shaped cover 16 by the pawl element 23 dodging into the housing interior of the housing 17 of the switching element 15. After the latch element 23 has passed the cover 16 in the closing movement, it springs back out of the housing 17 due to a spring element in the housing 17 (not shown). As a result, the pawl element 23 forms a stop for the cover 16 (FIG. 2) starting from this moment in the oppositely directed opening movement of the hinge 1 or the ejector unit 8 with the latching projection 24. FIG. 9 ). The coil spring 13 is held in the charged state, since the holding element 14 on Detent projection 24 of the pawl member 23 abuts. The holding member 14 and the coil spring 13 are thereby no longer movable relative to the transfer member 9. On the other hand, in an opening movement, caused by a user from the outside, the transmission member 9 can be displaced relative to the receiving member 10 (FIG. FIG. 10 ). In this movement, the holding element 14 is moved relative to the receiving member 10 on the first portion 18 of the receiving member 10.

In the FIGS. 11 and 12 a further hinge 26 according to the invention is shown in an open state, wherein on the hinge 26 a further ejector unit 27 according to the invention is arranged.

The ejector unit 27 comprises a further clip-like configured transmission member 28, a further helical spring 29 and a fork-like receiving member 30 (FIG. FIG. 13 ). The transfer element 28 has a stop element 31 for the helical spring 29, wherein the stop element 31 has an opening in which, in the mounted state of the ejector unit 27, a guide element 30a of the receiving element 30 is movably supported or guided ( FIGS. 14 and 15 ). The receiving member 30 comprises, in addition to the stick-like or rod-shaped guide element 30a, which is formed at a first end, at the opposite end a V-shaped head element 30b. In the mounted state of the ejector unit 27 on the hinge 26, the receiving member 30 is fixedly connected to the hinge arm 2 of the hinge 26 via the head element 30b ( FIG. 12 ).

In the assembled state of the ejector unit 27, the coil spring 29 is arranged between the stop element 31 and a further stop element 32 of the receiving member 30. The stop member 32 is formed like a clip and clipped onto the receiving member 30, for example.

In an opening or closing movement of the ejector unit 27, the transmission member 28 is rotated by a user from the outside or moved by a spring force of the coil spring 29 relative to the receiving member 30 along a longitudinal axis of the guide member 30a. The ejector unit 27 can not be deactivated, for example, since it has no switching means for this purpose.

In FIG. 16 an inventive furniture 33 is shown with a furniture body 34 and a furniture door 35 in the open state on the furniture body 34. The furniture door 35 is movably connected to the furniture body 34 via two hinges 36, 37 according to the invention. In addition, on the furniture body 34, a holding member 38a and the furniture door 35 a corresponding holding member 38b formed, for example, as a magnetic or magnetizable elements. The holding members 38a, 38b are designed to hold the furniture door 35 in a closed state on the furniture body 34.
