Description

Push-out device for movable furniture

The present invention relates to a pushing device for a movable portion (especially a rotatable door) of a piece of furniture of the first aspect of the patent application, the furniture portion having a specific one, the house having at least one wall or a plurality of walls.

An ejection device is shown in DE 20 2004 007 168 U1. DE 203 08 218 U1 shows a closing and damping device for a movable furniture part. DE 20 2005 020 872 U1 also shows a damper for the movable furniture part.

Therefore, electric motor ejection devices for revolving doors on furniture are known to those skilled in the art. However, this conventional solution is not suitable for practical use. Because they require a large construction space and the visual effect of the furniture (which is mounted on the furniture) is greatly affected.

This object is achieved by the object of the present invention.

The present invention is achieved by using the subject matter of claim 1 of the scope of the patent application. Further, the present invention relates to a piece of furniture (Patent No. 54 of the patent application) which has such an ejection device.

Another secondary feature of the present invention, which is also a further feature of the scope of other patent applications, is found in item 45 of the scope of the patent application. It relates to a cushioning function that buffers the closing of the movable furniture part, which is integrated into the ejection device in a simple manner.

Advantageous designs of the invention are found in the dependent claims.

The ejection device of the present invention is very flat in construction, making it suitable for fit into a wall of furniture.

Further, the subject matter of the subject matter of the present application, which is the subject matter of the present invention, is an advantageous further feature of the first aspect of the patent application, and is also an independent invention. Its purpose and advantages, such as the advantages of the subsidiary scope of the patent application, are shown in the accompanying drawings.

The present invention will be described in detail below with reference to the drawings.

Figure 1 shows a perspective view of a specific (e.g. box shape) having a plurality of walls, for example, which wall comprises a bottom wall (2), an upper wall or a cover for the bottom ( 3), two side walls (4) (5), and one rear wall (6).

The walls (2) to (6) are preferably aligned at right angles to each other, wherein the bottom wall (2) and the cover wall (3) are generally horizontally aligned, and the side walls (3) (4) are vertically aligned with the rear wall.

The home thus opened to one side can be closed with a movable furniture part - the revolving door (7) (see Figure 4), which can be on at least one or several single-axis hinges or multi-axis hinges (8) (in the figure 4 can be partially seen) pivoting about a (generally vertical) fixed or movable (or theoretically present) axis of rotation (D) and can be opened or closed.

The hinge (8) can be designed almost arbitrarily, the hinges that are preferably used are designed to be cushioned, and the door (7) should be oriented towards the closed position and/or the maximum open position (preferably from an opening angle of 45 ∘ to 50 ∘). The position starts) as a buffer.

In order to move the door (7) from its closed position (not shown) to an open position, a push-out device (9) is provided on the home specific (1), and the push-out device has a A driver section of a housing (10) and an actuator element movable relative to the housing (10). The actuator element [here a push rod (11)] is designed to move the movable furniture part when moving from the first position to the second position [in other words, here the door (7) is pressed or pressed Push], so that the door (7) pivots from the closed position to an open position about the axis of rotation (D).

The ejection device (1), for example in particular with regard to the construction of the example in FIGS. 2 to 5, is advantageously designed such that its thickness or construction height h is not greater than the thickness of the wall in which it is accommodated [ In Fig. 1, the thickness d] of the bottom wall (2) is larger.

Thus a construction height h of less than 20 mm (for example 19 mm) can be made in the vertical direction, so that the ejection device (1) can be integrated directly into an associated recess of a corresponding design or correspondingly sized bottom wall (2).

For this purpose, if a wall element is used as the bottom wall (2), it has a "mounting frame" (19) which is preferably surrounded. The mounting device is designed to accommodate at least one or one of a lower or upper transparent or opaque disc-shaped cover, such as wood, glass, plastic or/and metal (not visible here), wherein the cover is A flat receiving space is formed, and the ejection device (9) can be inserted into the receiving space and can be installed in the receiving space. Lighting elements may also be provided between the cover panels (often also referred to as "honeycomb panels") in the accommodation space to illuminate the interior and/or exterior spaces of the furniture.

When the cover is correspondingly designed to be not completely transparent, the ejection device cannot be (or cannot be clearly seen) from the outside. The side of the mounting frame (9) (see Figures 1 and 3) facing the door has a hole or a punch-out hole (12), and the free end of the action element [here the push rod (11)] is at least open Pass through the hole or punch out the hole (12) when in position.

The ejection device (11) can be mounted in any manner around the inner circumference of the surrounding mounting frame (19), thus using screws [for example on the mounting screw (29)] [embodiment of Fig. 8] or using a snap device (not shown here).

This results in a push-out device (1) which is integrated directly into the bottom wall and thus does not affect the outer cover of the furniture in the open or closed state, since thus only one effect of the push rod (11) can be seen substantially. The end section on the door and a section of the respective sensor element.

The ejection device should react to the pulling force or pressure acting on the furniture door, so that the pulling device is actuated by lightly pulling on the door (7) or by externally locking the door (7).

To perform this function, a sensing element (20) can be used which is mounted on the furniture in such a way that light pressure acting on the outside of the door can be sensed by it, for example by the pressure generated by the door being buckled.

It is preferred to use the signal generated from the sensor element (28) as a control signal when applying pressure, for example, to reach a control device integrated into the ejection device (1), the control device being beyond a certain At the limit, the push-out device is actuated, so the pusher (11) is removed and the door is opened.

For example, the sensor element (20) can likewise project through the aperture (21) of the mounting frame (19) in the direction of the door (7) with one end region. An element (not shown here) that can be correspondingly sensed on the door (7).

It is desirable to use an electrical or / electronic (eg capacitive) sensor device designed to position the door (or a sensible component that can be attached to the door) relative to the home - the sensor The motion of the component is sensed.

Simply slamming the door to actuate the ejection device, thus making the door turn on. It is therefore possible, for example, to make a revolving door furniture without handles for the cooking area.

1 to 6 show a first ejection device.

The housing (10) of the ejection device has two side strips (22) (23) (here, a T-shaped cross section), and the bottom sides of the bottom plate form a leaning area for two mutually spaced mounting plates. Or the mounting platelets (24) (25) rest against each other, in particular between the mounting plates, the original drive elements of the ejection device. This mounting plate is also used in the embodiment of Figures 7 and 8, wherein the spacers (22) (23) may be used instead of the spacers for mounting the small plates (24) (25).

A hole (26) can be formed in the profile strip (22) (23) to form the furniture element (2) on the fastening element or on the mounting frame, in particular on the mounting frame (19), which accommodates the ejection means.

The housing (10) of the drive unit is preferably in the same plane on the mounting frame (19).

The mounting plate (24) (25) is used in particular for mounting the original drive element of the drive unit, which protects the drive from damage.

In a preferred embodiment, the drive unit can have an electromechanical drive unit or an electromagnetic drive unit. If not in this way, it can also be a drive device with an energy storage device (such as a spring or a hydraulic cylinder), wherein these devices are tightened when the door is closed, and when the door is opened, the energy is released via the actuator element. . A purely mechanical solution can be achieved by using a spring (not shown) as a drive.

Here, the driving component of the driving device is a compact or small-sized electric motor (13) (see also the embodiment of FIGS. 7 and 8), and its output shaft passes through a "drive screw (14) [its The pitch should not cause "self-stopping" effect] A linker is used [here a multi-speed gearbox (15)]. The coupler has a plurality of upshifts (15a) (15b) (15c), each of which is formed by a "gear arrangement" that is fitted to each other, wherein the outer circumference of the final gear (16) has a segmented tooth configuration and is oriented The radius of the rotating shaft of the segment gear (16) has an axially extending pin (17) which is embedded in a slip ring (18) which preferably extends parallel to the closed door or in the closed state of the door It extends perpendicular to the main extension direction of the push rod (11).

If the segment gear (16) is rotated by the rotation of the electric motor (13), the pin (17) is co-rotated on the radius of the segment gear (16). In this way, the pin (17) is also moved in the slip ring (18), so that the push rod (11) embedded in the door (7) or fixed to the door (7) can be linearly moved by the slip ring (18). Therefore, it pushes up the door (7) in a direction of rotation of the segment gear (16).

Thus, the push rod (11) can be moved in and out, which pushes up the door (7) (see Figures 4 and 6) when it is removed. The door (7) should be manually closed, in other words, the door (7) is also closed by a correspondingly designed driving device with a motor, and the door is then pulled by the push rod, but the push rod is correspondingly fixed to the door (7) on. The closing process of the door (7) can be assisted by another closing device, thus utilizing a "close spring" (not shown here) in a hinge (8) that acts at least over a range of angles of rotation.

The embodiment of Figure 7 differs from the embodiment of Figures 1 to 6 in that instead of using a linearly movable pusher as an actuator element to push the door up, a lever element (27) is used [here A roller (28) is provided on the free end, the lever element is arranged on the segment gear (16) [here protruding radially from the segment gear (16)], the lever element can be moved from a position Installed A related opening in the frame (19) (not shown in this figure) is first pivoted toward the door (7) and then pressed from the inner door (7) and opened when the segment gear (16) is further driven. The ejection device (1) is also very flat in construction, but it requires a slightly larger opening in the mounting frame (19) to enable the "rotating lever member" (17) to pivot accordingly.

When closing the shield, the actuator element should be moved to a "turn-in position" or a "shift-in position" so that it does not lean against the closed door (7).

Not shown in the drawings is a control device for controlling the ejection device (1), which is preferably provided with a microprocessor and is equally mounted between the mounting small plates (24) (25).

It is conceivable to design the control device to be remotely controllable. In addition, it can be considered to be "self-learning" and "automatic diagnosis" within a certain range, so it is on the furniture (for example, the position at which the actuator element can be stopped, the pivoting angle on the door) It is found that the fault can be detected and displayed within a certain range, for example, optically displaying "fault" on an LED display (not shown here).

Figure 7 shows a modified side in which a sensor device (48) is integrated into the housing (10) with one of the removable sensor elements (49) (or a sensor tip) (which moves) The path can be sensed to move back and forth from the housing (10) in the direction of the door, which has the advantage that the movement of the forward and backward movements is easily distinguishable and can be easily initiated (for example after a power outage). The sensor can be located in the housing (10) peripherally adjacent to the housing, or - according to Figure 1 - is located near the side of the door back to the hinge, because here can be similar - first The opening angle is particularly accurately sensed in a smaller angular range.

It is of course also possible to provide the ejection device in or on the side wall (4) or (5) or in the cover wall (3). It is advantageous to have the ejection device fully integrated or fully integrated into a correspondingly sized furniture wall, i.e., the ejection device is up to the small openness of the actuator element and the sensor. Not seen by the external system or barely visible.

Ideally, the energy supply is achieved via a circuit portion of the furniture. For example, the circuit portion can be similarly integrated into one wall (2) - (6) of the furniture.

In terms of this control, there are various variations. For example, a practical example is that the speed of movement of the actuator element [rotary lever or push rod (11)] in the opening direction and the closing direction is not as fast.

In particular, two sensors or switches (30) for limiting the rotation angle may be disposed on the segment gear (16), and the movement is restricted in the opening direction and/or the closing direction, and the sensor or the switch (30) is preferably The adjuster can adjust the path (the actuator element can be removed via this path, or the segment gear can be rotated through this path). (See also Figure 7, where the sensor position can be seen).

If a hinge (8) is used [which has an automatic pull-in device that has an automatic pull-in spring that acts over a range of angles of rotation], if the push-out device acts over a range of angles of rotation, this range A range of rotation greater than the action of the automatic pull-in spring (typically an automatic pull-in angle of 35 ∘ to 45 ∘) is advantageous. Furthermore, the metric design of the drive of course requires that the spring of the hinge with the automatic pull-in device be more powerful.

It is also conceivable to monitor the rotation path with other squats. It is therefore possible to monitor or regulate the speed (which is related to the open path) via current/voltage.

The use of a non-self-stopping actuator (15) [especially a drive screw (14) with a pitch that is not self-sustained) has an advantage. That is, if necessary, the door can be closed by hand against the force of the ejection device in a simple manner.

The ejection devices of Figures 1 to 6 and Figure 7 are designed such that they can be used for left and right stop type doors (7), in other words, they can be used to turn the upper and lower mounting plates from "on" Go to "down" and use it in both cases. This simplifies the furniture manufacturer's plan. This results in an independent invention whereby the ejection device (1) is used in an asymmetrical design [here by using the push rod (11) provided asymmetrically on the housing (10)] by means of a turn 180" Doors in the left or right stop type can be used.

The ejection device (1) should preferably be mounted on the side of the door that faces at least one hinge (8), so that the push rod acts near the axis of rotation where a small path on the actuator element can cause movement of the door A large angle of rotation is swept by the actuator element.

We may consider the ejection device (1) to be selectively provided with a cushioning device, which is particularly useful in the case of mounting on a hinged door having no buffering.

An advantageous method here is to attach an action button on the housing (10) or home, which can be actuated by hand and, for example, in the region of the glass sheet.

The modification of Fig. 7 is designed such that it can be integrated into a furniture wall (for example, the size is 19 mm thick × 70 mm wide x 165 mm long), which is particularly advantageous in terms of vision. But if you don’t want to build or add a piece of furniture, It can be considered to be placed on a furniture wall or lowered into a furniture wall. For this purpose, the aforementioned device, in particular the one shown in Fig. 12, is provided, which has the configuration of the embodiment of Fig. 7, but the housing (10) consists of two half-shells which will be substantially closed and closed until the remaining opening For the actuator element or for the sensor.

Therefore, the housing can also have a T-shape according to Fig. 12, because, for example, the motor is slightly wider than the coupler, but basically, in theory, it can also completely break into a recess of a furniture wall (always to the action) The components are so far or only partially embedded (this is not a good method).

Figure 12 shows a perspective view of another ejection device.

9 to 11 show a modified example of the design of the actuator element. In particular, a push rod (11) that moves in a straight line is taken as an example.

According to another feature of the invention, the actuator element, in particular the push rod (11) (or "rotating lever"), is designed such that at least its free end can follow the rotary motion of the door on a curved path, and / or it is a friction reducing measure on the actuator element and / or the door (7), reducing the friction of the actuator element on the door (7).

Therefore, it is desirable to design the actuator element [especially the push rod (11)] such that at least its free end can follow the rotational movement of the door.

To this end, the pusher should be coupled to the rest of the pusher portion via at least one joint (31).

This joint can be designed, for example, in the form of a uniaxial rotating joint (Fig. 9b), or a biaxial rotating joint [having two rotating joints (31)] (Fig. 9a) or a ball joint (Fig. 9a) or other means.

In addition, a flat plane (33) on the pusher end (32) can follow the movement of the door (7).

According to another variant, a rolling body, for example a ball (34) or a roller (35), is provided on the free end of the push rod (11), so that within the push rod (11) and the furniture door (7) There is no sliding friction between the walls and rolling friction.

The pusher end (32) can also be connected to the rest of the pusher portion via an elastic section (35) which acts as a rotating joint (Fig. 10a), and it is also conceivable to push a section (36) or the entire push The rod is made of an elastomeric material (Fig. 9f).

In addition, the push rod (32) can be coupled to the push rod (11) via a spring [especially a coil spring (37)] which is pivotable in the area where it is pivotally connected to the push rod (Fig. 11c).

The push rod (32) can also be coupled to the push rod (11) via a joint string (39) (40) that can pivot about the region pivoted to the push rod (Fig. 11d, 11e).

According to Fig. 10b, the rod (46) or the cable (47) is pivotally connected to the pusher end of the joint end (31) in a parallelogram, and the joint is pivoted by the movement of the rod or the cable.

It is also conceivable to at least manufacture the free end of the push rod with a plain bearing material and/or to design the push rod tip (for example to completely round or use a corner of the corner to approach a strip, see figure 11g). The friction against the inner wall of the door is further reduced.

On the joint (31) - for example between the push rod end (32) and the rest of the push rod portion - one or several springs (41) can be provided so that when the door is closed, the free end of the push rod can be rotated The shaft (36) pivots back. One or more stops (42) may limit the rotational movement of the pusher end (32) (Fig. 11a). These measures can also be used in combination with the return spring (41) (42) (Fig. 11b, Fig. 11c), and the spring (41) can be used arbitrarily. Designed so it can be a spring or spring (Figure 10b, 11a~11e). An elastomeric element such as a ring (43) can also be used to perform the function of the spring if a metal spring is not used. (Figure 11d).

Finally, it is also conceivable to design the push rod (11') to be a linear escape, but to move on an arcuate path, which can be implemented, for example, by a gear (44), which is curved. [For example, the internal tooth structure (45) of the push rod (11') guided in a track (not shown) rolls.

13 to 17 are a section of the ejection device (9), which has an integrated buffering device or a buffering function when a movable furniture portion is opened and closed, and the furniture portion is here. It is then designed in the form of a door (7). The ejection device (9) should preferably be located at home. Especially in the way of the previous diagram (but not absolutely).

In order to move the door (7) from its closed position (not shown here) into an open position, the ejection device (9) is provided at home, preferably it may also have a drive section [the drive section has a shell The body (10)] and an actuator element (11) movable relative to the housing (10), the actuator element being designed in the form of a movable (particularly movable) push rod.

Here, the ejection device (9) has a cushioning device (50) for buffering the movement of the movable furniture portion.

Here, the damping device (50) is designed to cushion the closing movement of the movable furniture portion.

The actuator element is designed in the form of a multi-part pusher (11) in which the damping device (50) cooperates with the push rod, where it is integrated into the push rod (50).

To this end, the push rod (11) has a multi-part construction. The push rod (11) has two A pusher section (51) (52) for mutually interacting movement is provided with a buffering means (53) therebetween. Here, the damping means (53) is a spring, such as a coil spring which acts as a compression spring. The cushioning means can be designed in this manner or in other manners, such as a fluid-damped piston device (not shown) and/or a moving or linear motion spring, air or oil pressure damper. The rotation or the damper can be integrated into the ejection device in a particularly space-saving manner.

The pusher sections (51) and (52) are designed to be relatively movable relative to each other in a telescopic tube manner, in other words, a pusher section (51) is sleeved with a further pusher section (52), one of which is a pusher section ( 51) There is a blind hole-shaped recess or opening (54) into which the other pusher section (52) is embedded. A spring (53) is provided between the bottom of the opening (53) and the pusher step (52).

The driver of the ejection device (not shown here) acts on the first (here the outer one) pusher section (51).

The function of the device is as follows.

When the movable furniture portion [here the door (7)] is opened, the push rod (11) acts on the door (7) and pushes it up (Fig. 14). When the door (7) is released from the push rod (11), the spring (53) of the inner push rod section (52) [which was previously compressed in the closed state] from the push rod section (51) from the opening ( 54) Come out beyond the end of the pusher section (51) facing away from the housing (Fig. 15), which helps to open or accelerate the opening. In this state (Fig. 15), the door (7) is released from the push rod (11). The pusher (51) is thus pulled into the housing to its starting position (Fig. 11). An end stop (not shown here) may be provided in the push rod (15) to limit the movement of the push rod. Here, the design/coupling of the pusher section (51) (52) is such that the pusher section (52) does not completely come out of the recess (54) of the pusher section (51).

If the door (7) is closed again (Fig. 16), the door first closes the pusher section (52) that hits the advancement and presses it back into the recess (54) against the action of the spring (53). In this way, the movement of the door (7) is buffered, and its main advantage is revealed when the door is closed quickly, because the door does not swing back when it touches the home, and thus it can be determined that the re-fast action is avoided, so it is no longer necessary An additional bumper, the door also hits the putter slightly.

Therefore, when the door (7) is closed again, the pusher bar section (5) is also moved into the casing (10), and the spring (53) is designed such that the closing force of the movable furniture part is not (for example, it is The elastic door hinge acts to hold the spring (53) in the push-in position of Figure 13. Advantageously, the closing force of the movable furniture portion is such that the spring (53) acts on the opening force of the movable furniture portion (7).

In this way, the cushioning function can be used in a simple manner when the movable furniture part (here a door) is closed without affecting the appearance of the furniture and the ejection device.
