Description

Ejection device for movable furniture parts

The invention relates to an ejection device for a movable furniture part, in particular a rotatable door, according to the preamble of claim 1 and a piece of furniture with such an ejection device.

An ejection device of known type is shown in DE 20 2004 007 168 UL DE 203 08 218 Ul shows a closing and damping device for movable furniture parts. DE 20 2005 020 872 Ul also shows a damper for movable furniture parts.

Electromotive ejection devices for revolving doors on furniture are thus known per se. However, the known solutions are not very suitable for practical use, since they require a relatively large amount of space and greatly affect the appearance of the furniture to which they are mounted.

The solution to this problem is a first object of the invention.

The invention solves this problem by the subject matter of claim 1. It also also creates a furniture - claim 54 - with such from shock device or with an ejection device according to one of the other claims.

A sibling invention, but which is also suitable for the development of the subject matter of the other claims, is specified in claim 45. Such a damping function, which dampens the closing movement of the movable furniture part, integrated in a simple manner in the ejection device.

Advantageous embodiments of the invention can be found in the dependent claims.

The ejection device according to the invention builds so flat that it is suitable for being mounted in a furniture wall. The invention also provides the subject matter of claims 29, 30 and 31 and the dependent claims, which relate on the one hand advantageous embodiments of claim 1 but also further independent inventions whose tasks and advantages, as the advantages of the dependent claims result from the description of the figures.

Fig. 12 is a perspective view of another ejection device; and

13-17 show a section of an ejection device with an integrated damping device or function in successive steps when opening and closing a movable furniture part. 1 shows a perspective view of an exemplary box-shaped furniture body 1 with a plurality of walls, which here by way of example comprise a bottom wall 2 serving as a bottom, a top or top wall 3, two side walls 4, 5 and a rear wall 6,

The walls 2 - 6 are preferably aligned at right angles to each other, wherein the bottom wall 2 and the top wall 3 are usually horizontal and the side walls 3, 4 and the rear wall 6 are vertically aligned.

The thus open to one side furniture body is with a movable furniture part, a revolving door 7, which is shown in Fig. 4, closable, the at least one or more single or multi-axis hinge (s) 8 (in Fig. 4 partially visible ) can be pivoted about a - usually vertically aligned - fixed or in space moving (in any case theoretically existing) axis of rotation D and so opened and closed.

The hinges 8 can be formed almost arbitrarily. Preferably, hinges are used, which are designed to be damped and preferably dampen the movement of the door 7 towards the closed and / or maximum open position, in particular from an opening angle position of 40 ° to 50 °.

In order to move the door 7 from its closed position (not shown here) to an open position, an ejection device 9 is arranged on the furniture body 1, which has a drive section with a housing 10 and an actuator element movable relative to the housing 10. The actuator element, here a plunger 11, is designed to move the movable furniture part when moving from a first to a second position, i. Here, the door 7 to push or push, whereby the door 7 is pivoted about the rotation axis D from the closed position to an open position or position.

The ejection device 1 - see with regard to their exemplary structure in particular FIGS. 2 and 5 - is preferably advantageously designed such that their Thickness or height h is not greater than the thickness of the receiving wall, in Fig. 1 as the thickness d of the bottom wall. 2

Thus, it is possible to realize in the vertical direction a height h of less than 20 mm, for example a height h of 19 mm, so that the ejection device 1 can be integrated directly into a corresponding recess of a correspondingly designed or dimensioned bottom wall 2.

For this purpose, it is advantageous if a wall element with a preferably circumferential mounting frame 19 made of a plurality of collectable Einzelprofüelementen is used as the bottom wall 2, which is designed to at least one or preferably a lower and an upper transparent or non-transparent disc-shaped cover plate, for. made of wood, glass, plastic and / or metal (not visible here), wherein a flat receiving space is formed between these cover plates, in which the ejection device 9 can be used and in which it can be mounted. In / At the receiving space between the cover plates (often called honeycomb plate) and lighting elements for illuminating the furniture interior and / or outer space can be provided.

In a corresponding not completely transparent design of the cover plates, the ejection device is not or not appreciably visible from the outside. The mounting frame 19 (see FIGS. 1 and 3) has on its side facing the door to a bore or punching 12, which passes through the free end of the actuator, here the plunger 11, at least in the open position.

The ejector 11 may be mounted on the inner circumference of the peripheral mounting frame 19 in any desired manner, such as with screws e.g. on mounting screws 29 (embodiment of FIG. 8) or by means of a latching device (not shown here).

Thus, an ejection device 1 is realized, which is integrated directly into the bottom wall and thus the view of the furniture neither in the open nor in the closed This state is impaired, since essentially only an end section of the plunger 11 acting on the door and possibly a section of a separate sensor element can be seen from it.

Preferably, the ejection device responds to tension or pressure on the furniture door, so that it is possible to activate it by gently pulling on the door 7 or tapping the door 7 from the outside.

To realize this functionality, a sensor element 20 can be used, which is mounted on the furniture so that with him a slight pressure on the outside of the door is sensed, as it is generated for example by tapping the door.

It is expedient to use the signal emitted by the sensor element 20 when the pressure is applied as a control signal which, for example, is fed to a control device integrated into the ejection device 1, which activates the ejection device when a certain threshold value is exceeded, so that the plunger 11 extends and opens the door.

The sensor element 20 can project, for example, with an end region also through a bore 21 of the mounting frame 19 in the direction of the door 7. At the door 7, a correspondingly sensible element can be arranged (not shown here).

Suitably, the use of an electrical / electronic, e.g. capacitive, designed sensor device which is adapted to sense the movement of the door (or a sensible element attached to the door) relative to a sensor element on the furniture body.

A simple tap of the door then suffices to activate the ejector so that the door opens. This makes it possible to create a handle-less revolving door furniture, for example, for the kitchen area. FIGS. 1 to 6 show a first ejection device,

The housing 10 of this ejection device has two lateral - here in cross-section T-shaped - profiles 22, 23, the base legs on both sides support areas for two mutually spaced mounting plates or boards 24, 25 form, between which in particular the actual drive elements of the ejector are mounted , Such mounting boards are also used in the embodiments of FIGS. 7 and 8, where instead of the profiles 22, 23 and other spacers for the mounting boards 24, 25 are used

On the profiles 22, 23 holes 26 for attaching fasteners or for mounting on the furniture body, in particular on the mounting frame 19 of the ejection device receiving furniture wall 2 can be formed.

The housing 10 of the drive device is preferably flush with the mounting frame 19.

The mounting boards 24, 25 are used in particular for mounting the actual drive elements of the drive device, which protect them from damage to the outside.

In a preferred embodiment, the drive device can have an electromechanical drive unit or, alternatively, an electromagnetic drive unit. Alternatively, it can also have a drive device with an energy storage device such as a spring or a hydraulic cylinder, these devices being tensioned when closing the door and releasing their energy when opening the door via the actuator element. With a spring as a drive (not shown here), a purely mechanical solution is realized.

To the drive elements of the drive device here include a compact or small-sized electric motor 13 (see also the embodiments of FIGS. 7 and 8), which acts via a drive worm 14 with a preferably non-self-locking pitch on its output shaft to a transmission, here a multi-stage gear transmission 15. This has a plurality of gear ratios 15a, 15b, 15c, which are each formed of intermeshing gear arrangements, of which the last gear 16 has on its outer circumference a segment toothing and on a radius R to the axis of rotation of the segment gear 16 an axially extending pin 17, which in a preferably parallel to the closed door or perpendicular to the main direction of extension of the plunger 11 in the closed state of the door extending gate 18 engages, which is connected to the plunger 11.

If the segment gear 16 is rotated as a result of rotations of the electric motor 11, the pin 17 rotates on its radius on the segment gear 16 with. As a result, it takes along the slotted guide 18, with the pin 17 also displacing in the slotted guide 18, so that with the slotted link 18 the plunger 11 engaging or fixed on the door 7 is moved linearly, so that it moves in one direction of rotation Segment gear 16, the door 7 abuts.

In this way, it is possible to extend and retract the plunger 11 which, when extending, pushes open the door 7 (see FIGS. 4 and 6). The closing of the door 7 is preferably done manually, i.e. the plunger is e.g. retracted after opening the door 7 again. It is also conceivable, however, that closing the door 7 via a correspondingly dimensioned drive device also make an electric motor and pull the door again with the plunger, but then set accordingly to the door 7. The closing process of the door 7 can be assisted by a further closing device, thus by a closing spring acting in the hinge 8 at least over a certain angle of rotation (not shown in detail here).

The embodiment of FIG. 7 differs from that of FIGS. 1 to 6 in that instead of a linearly movable plunger as an actuator element for pushing the door a arranged on the segment gear 16 - here radially from the segment gear 16 outwardly projecting lever element 27 ( here at the free end with a roller 28 provided) is used - from a pivoted position by a corresponding opening in the mounting frame 19 (the latter in this figure, not shown) is first pivotable against the door 7, whereupon it presses on further rotation of the segment gear 16 from the inside against the door 7 and this opens. This ejector 1 builds flat. However, it requires a somewhat larger opening in the mounting frame 19, so that the rotary lever element 17 can be swiveled accordingly.

In the closed state, the actuator element is preferably moved in such a pivoted or retracted position that it does not bear against the closed door 7.

Not shown in the figures is the control device for controlling the ejection device 1, which is preferably provided with a microprocessor and which can also be accommodated between the mounting boards 24, 25.

It is conceivable to design the control device remotely controllable. It is also conceivable to interpret them to a certain extent as "self-learning" and "self-diagnosing", so that they can be attached to furniture, e.g. even the position of the abutment of the actuator element, the overtravelable pivoting angle on the door, etc., are detected and to a certain extent detects and indicates faults, e.g. visually on a LED "fault" (not shown here).

7 shows a variant in which a sensor device 48 is integrated into the housing 10, wherein an extendable sensor element 49 (or a sensor tip) whose travel path is sensible out of the housing 10 in the direction of the door and zurückbewegbar, which has the advantage that easily the back and the returning movement can be distinguished and that easily an initialization eg after a power failure is possible. The sensor can also be arranged outside the housing 10 close to this or, as shown in FIG. 1, close to the opposite side of the door facing away from the hinge, since in this case a particularly accurate sensing of the opening angle can be realized over a first smaller angular range , Of course, it is also possible to arrange the ejection device in or on one of the side walls 4, 5 or in the top wall 3. The complete integrable or complete integration of the ejection device a correspondingly dimensioned furniture wall has the advantage for each correspondingly dimensioned furniture wall the ejection device is possibly not visible or almost invisible except for small openings for the actuator element and a sensor from the outside.

The power supply ideally takes place via a power supply unit on the furniture, which is e.g. also in one of the walls 2 to 6 of the furniture can be integrated.

With regard to the control, different variants are possible, it makes sense, for example, in ÖffnungsS "and closing direction, the actuator, so the rotary lever or the plunger 11 to move at different speeds.

In particular, on the segment gear 16, two sensors or switches 30 limiting the angle of rotation may be arranged, which limit the movement in the opening and / or closing direction. It is advantageous to provide a controllability of the sensors or switches 30 in order to be able to set the path over which the actuator element can be extended or the segment gear wheel can be rotated (see also FIG. 7, after which the sensor position can be detected).

If hinges 8 are used which have a self-closing device with a self-closing spring, which act over a certain angle of rotation, it makes sense if the ejection device acts via a rotation angle which is greater than the angle of rotation over which the self-closing spring acts (self-closing angle, typically 35 ° to 45 °!). In addition, the drive must of course be dimensioned more powerful than the spring of the hinge with the Selbsteinzugsvorrichtung.

It is also conceivable to monitor the rotation path in other ways, such as current / voltage characteristics or monitoring the speed, which is in relation to the opening path. The use of a non-self-locking gear 15 (in particular also a drive screw 14 with non-self-locking pitch) has the advantage that it is possible in a simple manner to close the door manually against the effect of Ausstoßvomch- tion, if desired.

Both the push-out device of FIGS. 1 to 6 and FIG. 7 are designed so that they can be used both on the left and on the right hinged doors 7, ie, they are by means of a rotation through 180 ° such that the Upper and lower mounting plate is rotated from "top" to "bottom", usable in both installation situations, which simplifies the planning of the furniture maker. Thus, an independent invention is realized, according to which the ejection device 1 is implemented in an asymmetrical configuration (realized here by the plunger 11 arranged asymmetrically on the housing 10) by means of a rotation through 180 ° both on the left and on the right hinged doors.

The ejection device 1 is preferably mounted on the side facing the at least one hinge 8 side of the door, so that the plunger acts close to the axis of rotation, where with little travel on the actuator a large angle of rotation of the door movement is swept by the actuator.

It is conceivable to optionally provide the ejection device 1 with a damping device, which is particularly useful in retrofitting to doors, which are provided with non-damped hinges.

It is also useful, if necessary, to install a trigger button on the housing 10 or furniture body, which can be actuated manually and is provided, for example, in the region of the glass plates.

The variants of FIG. 7 are designed such that they can be integrated into a furniture wall (dimensions eg thickness 19 mm * width 70 mm * length 165 mm), which offers particular advantages, in particular with regard to optics. But it is also conceivable to open it up to put on a furniture wall or to sink them only partially in a furniture wall, if installation is not desired or a retrofitting of a piece of furniture to take place. For this purpose, the above devices, but in particular also those of FIG. 12, which has a structure of the type of FIG. 7, but wherein the housing 10 consists of two half-shells, which essentially - except for an opening for the Actuator element and possibly one for the sensor - close.

Thus, the housing may also have a T-shape in the manner of FIG. 12, since the motor is somewhat wider than the transmission, for example. Nevertheless, the basic suitability of theoretically remaining in a recess of a furniture wall completely (except for the actuator element) or - less preferred - partly - to be used, is retained.

Fig. 12 shows a perspective view of another ejection device.

FIGS. 9 to 11 show variants of the embodiment of the actuator element, illustrated in particular by the example of the linearly movable plunger 11.

Thereafter, according to a further invention, the actuator element, in particular the Stö ßεel 11 (or each of the rotary lever), designed such that at least its free end of the rotational movement of the door can follow a curved path and / or it is the friction of the actuator the door 7 reducing measure hit the actuator and / or on the door 7.

So it makes sense to design the actuator element, in particular the plunger 11 such that at least its free end of the rotational movement of the door can follow.

For this purpose, it makes sense to connect the plunger end 32 to the other plunger via at least one joint 31. This can be designed, for example, as a single-axis swivel joint (FIG. 9b), as a two-axis swivel joint with two swivel joints 31 (FIG. 9a), as a ball joint (FIG. 9a) or in another way.

Thus, a flat surface 33 on the plunger end 32 of the movement of the door 7 follow.

According to another variant, a rolling element such as a ball 34 or a roller 35 is arranged at the free end of the plunger 11, so that instead of sliding friction between the plunger 11 and the inner wall of the furniture door 7 occurs.

The plunger end 32 may also be connected to the rest of the plunger via an elastic portion 35 (FIG. 10a) acting as a hinge. It is also conceivable to manufacture a section 36 or the entire plunger from an elastomeric material (FIG. 9f).

The plunger end 32 can also be connected via a spring, in particular a helical spring, 37 to the plunger 11, which is pivotable about its articulation region on the plunger (Fig. L lc).

The plunger end 32 can also be connected via a link chain 39, 40 to the plunger 11, which is pivotable about its Anienkbereich on the plunger (Fig. Id 1, e).

According to FIG. 10b, rods 46 or cables 47 are articulated in the manner of a parallelogram on the ram end to joints 31 in order to pivot this by moving the rods or cables.

It is also conceivable to manufacture at least the free end of the plunger from a slide-bearing material and / or to design the plunger tip (for example, completely or partially rounded or approximated by bevels of the corners of a rounding, see Fig. 1 Ig), that the friction to Door inner wall in turn is reduced. A spring or a plurality of springs 41 on the joints 31 - eg between the plunger end 32 and the rest of the plunger 11 - can / can be provided to zurückzuschwenken the free plunger end when closing the door to the pivot 31. One or more stops 42 may limit the rotational movement of plunger end 32 (FIG. 1a). The measures stop and return spring 41, 42 can also be combined (Fig 11 b, 1 Ic). The springs 41, can be configured as desired, as screws or leaf springs (Fig. 10b, 11 a - e). Instead of a metal spring and an elastomer element such as a ring 43 for the realization of the spring function is used (Fig. Hd).

Finally, it is conceivable to make the plunger 11 'not linearly extendable but to move it on an arcuate path, which can be realized, for example, with a toothed wheel 44 that is fixed to the internal toothing 45 of an arcuate, e.g. guided in a lane (not shown here) ram 11 'unrolls.

13-17 show a section of an ejection device 9 with an integrated damping device or function in successive steps during the opening and closing of a movable furniture part, which in turn is designed here as a door 7. The off shock device 9 is again preferably on the furniture body, in particular - but not mandatory - arranged in the manner of one of the preceding figures.

In order to move the door 7 from its closed position (not shown here) into an open position, the ejection device 9 is arranged on the furniture body, which preferably again has a drive section with a housing 10 and an actuator element 11 that is movable relative to the housing 10 movable, in particular displaceable plunger is formed.

In this case, the Ausstoßvoπϊchtung 9 on a damping device 50 for damping the movement of the movable furniture part. Here, the damping device 50 is designed for damping a closing movement of the movable furniture part.

The actuator element is designed as a multi-part plunger 11, wherein the damping device 50 is associated with the plunger. It is integrated here in the ram 50.

For this purpose, the plunger 11 has a multi-part construction. The plunger 11 has two relatively movable plunger sections 51, 52, between which a damping means 53 is arranged. Here, the damping means 53 is a spring, for example a helical spring acting as a compression spring. However, the damping means may also be designed in other ways, for example as a fluid-damped piston arrangement (not shown here) and / or as a rotationally or linearly acting spring, air or hydraulic damper. Rotary dampers are particularly space-saving integrated into the ejection devices.

The plunger sections 51 and 52 are telescopically displaceable relative to each other, i. the one plunger section 51 surrounds the other plunger section 52, wherein the one plunger section 51 has a blind hole-like recess or opening 54 into which the further plunger section 52 is inserted. The spring 53 is disposed between the bottom of the opening 53 and the tappet portion 52.

The drive of the ejection device (not shown here) acts on the first, here outer plunger section 51.

The function of this arrangement is as follows.

When opening the movable furniture part, here the door 7, the plunger 11 acts on the door 7 and abuts them (FIG. 14). As soon as the door 7 is released from the plunger 11, the spring 53, compressed in the closed state, of the inner plunger section 52 pushes outwardly from the plunger section 51 out of the opening 54 beyond the end of the plunger section 51 facing away from the housing (FIG. 15), which is supplementary or accelerating opening can act. In this state (FIG. 15) the door 7 is released from the disturbance. 11. Then the plunger 51 is retracted into its starting position into the housing (FIG. 11). There may be provided an end stop for limiting the extension movement of the plunger 52 in the plunger 51 (not shown here). The design / coupling of the plungers 51 and 52 is here such that the plunger 52 does not emerge completely from the recess 52 of the plunger 51.

When the door 7 is closed again (FIG. 16), it initially strikes the advanced plunger section 52 when closing and pushes it back into the recess 54 against the action of the spring 53. Thus, the movement of the door 7 is damped. The main advantage comes from a quick closing, as the door does not swing back when hitting the body and thus reliably avoids another - fast - release. An additional damper is no longer necessary. The door will also hit the pusher quieter.

Upon further closing of the door 7 and the outer plunger section 51 is then retracted into the housing 10. The spring 53 is designed such that the closing force of the movable furniture part, e.g. caused by resilient door hinges, the spring 53 in the retracted position of FIG. 13 holds. It is advantageous that the closing force of the movable furniture part is greater than an opening force of the spring 53 on the movable furniture part 7.

Such a Dämpmngsfunlction when closing the movable furniture part, here the door is realized in a simple manner, without the appearance of the furniture and the ejection device is affected. reference numeral
