Description

The present application is a continuation of International Application PCT/AT2023/060421 filed on Dec. 1, 2023. Thus, all of the subject matter of International Application PCT/AT2023/060421 is incorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention relates to a pull-out guide and to a piece of furniture with such a pull-out guide.

Lockable pull-out guides, especially for furniture, are known in many designs in the prior art. For example, U.S. Pat. No. 9,725,924 B2 and EP 2 424 404 B1 disclose pull-out guides consisting of at least two rails and a closing device, wherein an adjusting element engages in a bolt receiver to lock the relative movement of the at least two rails.

However, the state of the art has various disadvantages.

On the one hand, a pull-out guide with a closing device or a locking mechanism always consists of a large number of individual parts, such as an adjusting element, a bolt receiver, an action transmitter, spring devices, and the like. A space-saving and efficient design of all these components within a given construction volume, which is usually extremely limited in furniture, continues to represent a major challenge.

On the other hand, pull-out guides often have drive devices in addition to closing devices, which, for example, facilitate the opening and/or closing of a piece of furniture. Such drive devices consist of additional individual parts, which make it difficult to design a pull-out guide with drive devices, in particular ejection and/or retraction devices, in a space-saving and simple manner, and at the same time complicate the assembly of all these components.

SUMMARY OF THE INVENTION

The task of the present invention is therefore to at least partially remedy the disadvantages of the prior art and to provide an improved pull-out guide compared to the prior art, which is characterized in particular by a more space-saving design and/or simplified assembly. The task is also to provide a piece of furniture with such an improved pull-out guide.

In a first aspect, this task is solved by means of an pull-out guide as described below, namely by a pull-out guide for movably mounting a first furniture part on a second furniture part, comprising:

    • a first rail to be connected to the first furniture part and at least one second rail to be connected to the second furniture part, wherein the two rails are mounted so as to be movable relative to each other, preferably wherein a further rail is mounted so as to be movable between the two rails,
    • at least one drive device by means of which the two rails can be driven relative to each other,
    • wherein at least one closing device with at least one electrically operating adjusting element is provided, wherein the at least one adjusting element engages in the drive device in a closed position and releases the drive device in a release position.

Since the locking device is locked by the adjusting element engaging in the drive device and released by the adjusting element not engaging in the drive device, the drive device functions as a bolt receiver. This means that the drive device fulfills both the function of a drive and the function of a component of a locking mechanism and is therefore dual-functional. As a result, at least one component, namely a lock receiver, can be omitted, which leads to a more efficient design and saves space.

In a second aspect, this task is solved by means of a pull-out guide as described below, namely by a pull-out guide for movably mounting a first furniture part on a second furniture part, comprising:

    • a first rail to be connected to the first furniture part and at least one second rail to be connected to the second furniture part, wherein the two rails are mounted so as to be movable relative to each other, preferably wherein a further rail is mounted so as to be movable between the two rails,
    • at least one drive device with which the two rails can be driven relative to each other,
    • wherein at least one driver is provided which can be brought into operative connection with the at least one drive device, and at least one closing device with at least one electrically operable adjusting element is provided, wherein the at least one driver and the at least one closing device are arranged on a common base plate and can be fastened, preferably detachably, together as a connected assembly unit to one of the two rails, preferably to one rail, which is to be connected to an immovable furniture part, or to one of the two furniture parts.

Because the driver and the closing device are arranged on a common base plate, the base plate has a dual function. The common base plate is therefore essential for the functional connection between the driver and the drive device on the one hand, and for the functional connection between the closing device and the drive device on the other hand. This common base plate thus results in a more efficient design. In addition, the common base plate with driver and closing device as a connected assembly unit simplifies assembling, since only one assembly unit needs to be attached to one of the two rails instead of mounting the driver and closing device as separate units on the rails.

According to a preferred embodiment of the pull-out guide, the at least one drive device has at least one force storage member, preferably wherein the force storage member has at least one spring element. The at least one force storage member can be charged by a relative movement of the two rails and/or can be discharged by a relative movement of the two rails, and/or the drive device is detachably fastenable and/or fastened to one of the two rails, preferably on a rail which is to be connected to a movable furniture part.

In a preferred embodiment, the spring element may be a bending spring and/or a torsion spring and/or a disc spring and/or an evolute spring and/or a ring spring and/or a diaphragm spring, wherein the spring device is made at least partially of metal and/or plastic and/or a composite material.

Furthermore, protection is sought for a piece of furniture with at least a first and a second furniture part and at least one pull-out guide according to the invention. The first rail of the pull-out guide is connected to the first furniture part, and the second rail of the pull-out guide is connected to the second furniture part. Preferably, the first furniture part is designed as a drawer and the second furniture part is designed as a furniture body.

FIG. 1 shows a piece of furniture 42 in perspective view, which consists of a furniture body 44 and four drawers 43. The furniture body 44 has a top panel 47 and two side panels 48 on the left and right sides. The top drawer 43 of the four drawers 43 is shown in an open position, with the rails 4, 5, and 6 in a fully extended position, and the remaining three drawers 43 in a closed position. The rails 4, 5, and 6 are not visible due to the top drawer 43 and the furniture body 44.

FIG. 2 shows the piece of furniture 42 from FIG. 1 in a perspective view, with the top panel 47 of the furniture body 44 hidden. This provides a clear view of the pull-out guide 1 with the rails 4, 5, and 6 fully extended.

In contrast to FIG. 1, at least the second rail 5 of the pull-out guide 1 is visible in this illustration, whereby the second rail 5 is connected to the second furniture part 3, specifically in FIG. 2 to the furniture body 44. The connection between the second rail 5 and the furniture body 44 can be a detachable and/or non-detachable connection, for example a screw connection. The first rail 4 and a further rail 6 are visible in the following figures.

It should be noted at this point that a pull-out guide 1 can be used for any type of furniture part and is therefore not limited to the embodiments shown here. The pull-out guide 1 has a first rail 4, which is connected to a first furniture part 2, and a second rail 5, which is connected to a second furniture part 3. As shown here, the first furniture part 2 can be a movable furniture part, specifically a drawer 43, and the second furniture part 3 can be an immovable furniture part, specifically a furniture body 44, but a pull-out guide 1 is not limited to drawers and furniture bodies.

FIG. 3 shows the piece of furniture from FIG. 2 in a perspective side view. Due to the absence of the top panel 47, the interior of the piece of furniture 42 is visible, specifically the area where the drawer is located when retracted. Thus, part of the pull-out guide 1 is visible, which is connected to the side panel 48. Due to the extended drawer 43, only the second rail 5 of the pull-out guide 1, which is connected to the second furniture part 3, specifically to the side panel 48, is visible.

As shown in FIGS. 2 and 3, a piece of furniture 42 is provided, wherein the piece of furniture 42 comprises at least a first and a second furniture part 2, 3 and at least one pull-out guide 1 according to the invention. The first rail 4 of the pull-out guide 1 is connected to the first furniture part 2 and the second rail 5 of the pull-out guide 1 is connected to the second furniture part 3, preferably wherein the first furniture part 2 is designed as a drawer 43 and the second furniture part 3 is designed as a furniture body 44.

FIG. 4 shows the piece of furniture 42 from FIG. 3, whereby in this illustration the top drawer 43, i.e. the first furniture part 2, which is connected to the first rail 4, is hidden. As a result, one of the two pull-out guides 1 is fully visible, while the second pull-out guide 1 is only partially visible, specifically only the extended first rail 4 and part of the drive mechanism 7.

As shown in FIG. 4, the pull-out guides 1 each comprises a first rail 4, a second rail 5, and a further rail 6 located between them. The second rail 5 is connected to the second furniture part 3, specifically to the side panel 48. A drive device 7 is attached to the first rail 4.

As can be seen in FIGS. 3 and 4, the first furniture part 2, for example in the form of a drawer 43 and/or a movable furniture part 16, can have a lower side 20 to which the upper side 21 of the rail 10 connected to the movable furniture part 2, here the first rail 4, can be connected. In this embodiment, the rail 15 connected to the immovable furniture part is connected to the furniture body 44 and is the second rail 5.

As can be seen in FIGS. 3 and 4, the pull-out guide 1 may be designed as an underfloor guide and preferably arranged on an underside 20 of the first furniture part 2.

However, the additional rail 6 is only optional; a pull-out guide 1 with only two rails is also possible.

The rails of the pull-out guide 1 can be moved relative to each other. In other words, the rails of the pull-out guide 1 can be moved telescopically. The rails of the pull-out guide 1 are shown in FIG. 5 in the position where they are fully extended relative to each other.

The pull-out guide 1 has a drive device 7 and a closing device 8 in addition to the existing rails 4, 5, and 6.

The drive device 7 can be used to drive the existing rails of the pull-out guide 1 relative to each other. As shown in FIG. 5, it is possible to use an ejection device 45 and/or a retraction device 46.

An ejection device 45 serves to extend the first rail 4 relative to the second rail 5 and thereby bring the pull-out guide 1 into an extended position.

The retraction device 46 serves to retract the first rail 4 relative to the second rail 5 and thereby bring the pull-out guide 1 into a retracted position.

It may be provided that between the first rail 4 to be connected to the first furniture part 2 and the at least one second rail 5 to be connected to the second furniture part 3, there is at least one, preferably several, load-transferring rolling element, preferably wherein the at least one rolling element is mounted in at least one carriage, and/or wherein one of the two rails 4, 5 has at least one longitudinal profile on which the other of the two rails is mounted.

FIG. 20 shows the front view of the connected assembly unit 14 or the closing device 8 from FIG. 18.

In the view of the connected assembly unit 14 in FIG. 20, the driver 12, the adjusting element 9, the action transmitter 37, the electric motor 31, the rocker switch 55, the switch 34, and the control circuit 30 can be seen on the base plate 13 from left to right, with the electrical line 33 running to the right from the control circuit 30.

It may be provided that an energy interface 41 is provided for connection to a remote energy supply network and/or to an energy storage device, preferably in the form of a battery and/or an accumulator, for supplying energy to at least one part, preferably a control circuit 30 and/or an electric motor 31, of the closing device 8.

The energy interface 41 may be part of the control circuit 30 and/or the electrical line 33.

As shown in FIG. 20, the electrical line 33 may have an energy interface 41 via which the energy supply to the pull-out guide 1, in particular to the closing device 8, is enabled, wherein the energy interface 41 is only shown schematically in FIG. 20.

FIG. 21 shows a detailed view of house FIG. 20.

As shown in the detailed view H in FIG. 21, it may be provided that the at least one adjusting element 9, in particular in the form of a substantially elongated component, has:

    • an adjusting element hook 24, which engages in the drive device 7 in the closed position of the at least one adjusting element 9, and/or
    • an adjusting element fastening device 25, wherein the at least one adjusting element 9 is fastenable and/or fastened by means of the adjusting element fastening device 25 to a part of the closing device 8, preferably to a base plate 13, and/or
    • at least one receiving device 26, preferably wherein the at least one receiving device 26, in particular in the form of a projection 27, is suitable for receiving at least one spring device 18, and/or the at least one receiving device 26, in particular in the form of a recess 28, is suitable for receiving a limiting device 29.

The functioning of the spring devices 18 and the receiving devices 26 will be explained in more detail later.

FIGS. 22 to 41 show a second embodiment of a pull-out guide 1. The above statements apply analogously to this second embodiment, which is why only differences or more detailed explanations will be discussed below.

FIG. 22 shows a perspective view of the second embodiment of a pull-out guide 1, wherein the pull-out guide 1 is shown in the extended position.

In contrast to the previous embodiment, the drive device 7 in this case only has a feed device 46 and a differently designed synchronization rod receiver 49.

FIG. 23 shows detail view I from FIG. 22. The second variant of the synchronization rod receiver 49 is particularly visible here.

FIG. 24 shows the detailed view J from FIG. 22. This detailed view of the second embodiment corresponds analogously to the detailed view A of the previous embodiment in FIG. 6.

FIG. 25 shows a perspective view of a further embodiment of a pull-out guide 1, wherein the pull-out guide 1 is shown in the retracted position.

FIG. 26 shows the detailed view K from FIG. 25. This detailed view of the second embodiment corresponds analogously to the detailed view B of the previous embodiment in FIG. 8.

FIGS. 27 to 33 correspond analogously to the views of the previous embodiment in FIGS. 9 to 19.

FIG. 34 shows the connected assembly unit 14 and the synchronization rod receiver 49 of the second embodiment.

In this view, the pull-out guide 1 is in the retracted position, so that the synchronization rod receiver 49 is locked by the adjusting element 9.

It should be noted at this point that the adjusting element 9 can engage and/or release any other part of the drive device 7. In the two embodiments described above, the engagement and release take place between the adjusting element 9 and the synchronization rod receiver 49 of the drive device 7. It is also conceivable that the engagement and release take place between the adjusting element 9 and another part of the drive device 7 or at another location of the drive device 7.

FIG. 35 shows the detailed view N from FIG. 34.

In the detailed view N of FIG. 36, the adjusting element 9 is in the closed position. As can be clearly seen in FIG. 35, the adjusting element hook 24 of the adjusting element 9 engages in the synchronization rod receiver 49 in such a way that the relative movement of the two rails 4, 5 in at least one direction is blocked by the contact of the at least one adjusting element 9 with the drive device 7 at at least one contact point, preferably in a form-fitting manner.

FIG. 36 shows a perspective view of the connected assembly unit 14 and the synchronization rod receiver 49 of the second embodiment, wherein the adjusting element 9 is in the release position.

FIG. 37 shows the detailed view O from FIG. 36.

The detailed view O in FIG. 36 shows that the adjusting element hook 24 does not engage in the synchronization rod receiver 49 and does not block relative movement of the rails 4, 5.

Due to the fact that the electric motor 31 with the eccentric 31 and/or motor actuator 40 is in the position shown in FIG. 37, one of the existing spring devices 18, namely the release spring devices 57, can push by its spring force the part of the action transmitter 37, in the region of which the release spring device 57 is arranged, away from the base plate 13. As a result, the action transmitter 37 can pivot in a rotary movement about the axis of rotation 23, thereby activating the limiting device 38.

The limiting device 38 can be arranged at that end of the action transmitter 37 which is opposite the end of the action transmitter 37 in contact with the electric motor 31. The limiting device 38 can be in contact with the adjusting element 9 by means of a receiving device 26, as shown in FIG. 37 by a recess 28.

By moving the action transmitter 37, triggered by the release of the motor actuator 40 and the spring force exerted by the release spring device 57, the limiting device 38 can move the adjusting element 9 in the same swivel direction as the action transmitter 37 itself. In this way, the adjusting element 9 can be brought into the release position, which can be seen in FIG. 37.

FIG. 38 shows another view of the connected assembly unit 14 and the synchronization rod receiver 49 of the second embodiment, wherein the adjusting element 9 is in the release position.

FIG. 39 shows a detailed view of pause FIG. 38.

The detailed view of Paus FIG. 38 clearly shows how the adjusting element 9 can be moved into the release position and/or held there.

As already described, it may be provided that the adjusting element 9 is pressed against the base plate 13 in its release position. In this way, it is possible that the adjusting element hook 24 no longer engages in the drive device 7, as shown here in the synchronization rod receiver 49, but instead releases it, thereby allowing the relative movement of the rails 4, 5, as shown here in the longitudinal direction 22, to be permitted.

The adjusting element 9 is pressed against the base plate 13 by the limiting device 38, whereby the limiting device 38 engages in the receiving device 26, as shown in FIG. 39 in the form of the recess 28. When the action transmitter 37 is pivoted counterclockwise, the limiting device 38 also pivots the adjusting element in the same direction, as shown in FIG. 39. The counterclockwise pivot refers to a leftward movement about the axis of rotation 23 in FIG. 39.

It may be provided that a base plate 13 of the closing device 8 limits movement of the at least one adjusting element 9 in at least one direction.

The adjusting element can be moved into the release position without the electric motor 31 and the action transmitter 37 being involved, in particular in a triggering manner. It may be provided that when the adjusting element 9 is passed over by the synchronization rod receiver 49 or by one of the existing rails or by an actuator 19 connected to the rails, the adjusting element 9 is displaced into the release position.

It may therefore be provided that the at least one adjusting element 9 blocks a relative movement of the two rails 4, 5 in a closed position and allows such movement in a release position, wherein at least one spring device 18, such as the closing spring device 58 shown in FIG. 39, is provided which biases the at least one adjusting element 9 into the closed position, wherein the at least one adjusting element 9 can be displaced into the release position by one of the two rails 4, 5 or an actuator 19 connected thereto during a movement in a first direction relative to the other rail 4, 5 counter to the force exerted by the spring device 18.

As shown in FIGS. 38 and 39, the synchronization rod receiver 49 can be the actuator 19 connected to one of the two rails 4, 5. In this case, the synchronization rod receiver 49 is connected to the first rail 4 via the drive device 7. This embodiment is not to be understood as limiting, since any other actuator 19 connected to one of the two rails 4, 5 is conceivable.

This displacement of the adjusting element 9 can also lead to the release position of the adjusting element 9, as shown in FIG. 39, but the spring device 18, which is located between the action transmitter 37 and the adjusting element 9, specifically the closing spring device 58, moves the adjusting element 9 back to the closed position after it has been passed over.

It may therefore be provided that, after being displaced by further movement of the rail 4,5 or the actuator 19 connected thereto, the at least one adjusting element 9 can be returned to the closed position by the spring device 18, such as the closing spring device 58 shown in FIG. 39.

FIG. 40 shows another view of the connected assembly unit 14 without the synchronization rod receiver 49 of the second embodiment, wherein the adjusting element 9 is in the closed position.

It may be provided that the base plate 13 has at least one, preferably two, intersection points 17, a base plate bolt 51, a base plate hook 52, a base plate slot 53, and a base plate stud 54. These features may be provided for fastening the base plate as a connected assembly unit 14 to one of the existing rails 4, 5, or 6, which is described in more detail in the following figures.

FIG. 41 shows a detailed view Q from FIG. 40, in which the base plate bolt 51, the base plate hook 52, the base plate slot 53, and the base plate stud 54 are shown in detail once again.

FIG. 42 shows a second rail 5 and a connected assembly unit 14 in an unconnected state.

FIG. 43 shows a detailed view of R of FIG. 42.

The detailed view R shows the part of the base plate 13 which comprises the base plate bolt 51, the base plate hook 52, the base plate slot 53 and the base plate stud 54. Next to this is shown the part of the second rail 5 which has the corresponding receiving devices for these features of the base plate 13.

It may be provided that the base plate bolt 51 can be connected to the base plate bolt receiver 59, the base plate hook 52 to the base plate hook receiver 60 and/or the base plate stud 54 to the base plate stud receiver 61. As shown in FIG. 43, it may be provided that the respective connections between the base plate 13 and the second rail 5 are made via detachable plug connections. Other detachable or non-detachable connections are also conceivable.

FIG. 44 shows the second rail 5 and the connected assembly unit 14 in a state where they are not yet fully connected.

In FIG. 44, the connected assembly unit 14 is connected only at one point, specifically via the base plate bolt 51 of the base plate 13 in conjunction with the base plate bolt receiver 59 of the second rail 5. The intersection points 17 of the base plate 13 and the rail 5 are in an unconnected state.

FIG. 45 shows a detailed view of S of FIG. 44.

Detail view S shows a state in which the base plate 13 is connected to the second rail 5 by the base plate bolt 51. The base plate bolt 51 and the base plate bolt receiver 59 are connected to each other via a plug connection. In this way, it is possible for the connected assembly unit 14 to be arranged so that it can pivot relative to the second rail 5 via this plug connection as a pivot point. This allows the connected assembly unit 14 to be pivoted in the direction of the rail 5, whereby, in the course of the continuous rotational movement of the assembly unit 14 and the rail 5 relative to each other, the remaining connecting elements can also come into contact with each other, specifically the base plate hook 52 with the base plate hook receiver 60, the base plate studs 54 with the base plate stud receivers 61, and the two intersection points 17 of the assembly unit 14 with the intersection points of the rail 5.

It may therefore be provided that one of the two rails 4, 5 and a base plate 13 each have at least one intersection point 17 via which the base plate 13 can be fastened and/or is fastened to one of the two rails 4, 5, wherein the intersection points 17 fastened to one another form a non-destructively detachable form-fitting and/or force-fitting connection.

A form-fitting connection can also be described as positive locking or as positive fit.

A force-fitting connection can also be described as frictional connection.

The base plate slot 53 may be provided for the suspension of the base plate stud 54.

FIG. 46 shows the second rail 5 and the connected assembly unit 14 in the fully connected state.

FIGS. 42 to 49 show the simple assembly of the connected assembly unit 14 on one of the rails, specifically the second rail 5, of the pull-out guide 1. Assembly can be carried out at any time, i.e., the assembly unit 14 can already be connected to the pull-out guide 1 before the pull-out guide is attached to furniture parts or even afterwards. In addition, the assembly unit 14 can also be easily removed from the pull-out guide 1, specifically the second rail 5, in reverse order. This offers the advantage of being able to retrofit, convert, and/or replace the connected assembly unit 14 as a whole or in parts as a result of wear, damage, and/or further developments.

FIGS. 50 and 51 show a third embodiment of a closing device 8. The above statements apply analogously to this embodiment of a closing device 8.

In contrast to the previous embodiments, FIG. 50 and the exploded view in FIG. 51 show that the adjusting element 9 is not pivoted orthogonally to the base plate 13, but rather that the pivoting movement takes place in a plane parallel to the base plate 13.
