Description

[0001] The present invention relates to a pull-out guide and to a piece of furniture with such a pull-out guide.

[0002] Lockable drawer slides, especially for furniture, are known in many designs in the prior art. However, a disadvantage of the prior art is that locking mechanisms can be prone to malfunction. For example, it can happen that an actuator unintentionally enters a closed position, preventing an extended drawer slide from being returned to its retracted position.

[0003] US 2014 / 021843 A1 shows a pull-out guide and a separate, electrically attached locking device on the furniture.

[0004] Even in state-of-the-art systems, a switch can detect the positions of the actuator and control the locking mechanism accordingly. If, in such a case, the power supply to the locking mechanism fails, for example due to a power outage or a depleted battery, the locking mechanism malfunctions and the drawer slide can no longer be opened or closed.

[0005] Another disadvantage of the current state of the art is that locking devices take up space, which negatively impacts the storage space of the furniture parts connected to the pull-out guide.

[0006] The object of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide an improved extension mechanism compared to the prior art, which is characterized in particular by a less failure-prone and / or less space-consuming design. The object is further to provide a piece of furniture with such an improved extension mechanism.

[0007] This problem is solved by the features of claims 1 and 18.

[0008] In a first aspect, this problem is solved by means of an extension guide according to claim 1, namely by an extension guide for the movable mounting of a first furniture part on a second furniture part with a first rail to be connected to the first furniture part and at least a 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, wherein at least one locking device with at least one electrically actuated actuator is provided, wherein the at least one actuator blocks a relative movement of the two rails in a closing position and allows it in a release position, wherein at least one spring device is provided which biases the at least one actuator into the closing position, wherein the at least one actuator can be displaced into the release position by one of the two rails or an actuator connected thereto when moving in a first direction relative to the other rail against the force exerted by the spring device.

[0009] The spring mechanism thus holds the actuator in its closed position. Only with a sufficiently strong force opposing the spring force of the spring mechanism, and only with movement in a first direction of one rail relative to the other rail, can the actuator be displaced into the release position.

[0010] This results in the advantage of the extension guide that, regardless of the position of the actuating element, the two rails can always be brought into a maximum end position relative to each other in a first direction.

[0011] In a preferred embodiment, the actuating element is displaced by manually moving one of the two rails in the first direction relative to the other rail, for example, by a person closing a drawer of a piece of furniture, before or when the two rails are retracted relative to each other. Subsequently, the actuating element can be reset by the spring device, thus preventing the rails from moving relative to each other in any other direction. This reduces the susceptibility of the locking mechanism to malfunctions.

[0012] Further advantageous embodiments of the arrangement are defined in the dependent claims.

[0013] According to a preferred embodiment of the arrangement, the at least one drive device has at least one energy storage device, preferably wherein the energy storage device has at least one spring element, wherein the at least one energy storage device can be charged and / or discharged by a relative movement of the two rails, and / or the drive device can be detachably attached and / or fastened to one of the two rails, preferably to a rail which is to be connected to a movable part of the furniture.

[0014] 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 volute spring and / or a ring spring and / or a diaphragm spring, wherein the spring device consists at least partially of metal and / or plastic and / or a composite material.

[0015] Furthermore, protection is sought for a piece of furniture with at least one first and one second furniture part and at least one extension guide according to the invention, wherein the first rail of the extension guide is connected to the first furniture part and the second rail of the extension guide is connected to the second furniture part, preferably wherein the first furniture part is designed as a drawer and the second furniture part as a furniture body.

[0094] As in Fig. 20As shown, the electrical line 33 can have an energy interface 41, via which the energy supply of the extension guide 1, in particular the locking device 8, is enabled, whereby the energy interface 41 is only shown schematically in Fig. 20 is shown.

[0095] Fig. 21 The detailed view H shows Fig. 20 .

[0096] It can be seen in the detailed view H in Fig. 21 It is shown that the at least one actuating element 9 has, in particular in the form of a substantially longitudinally elongated component: an actuating element hook 24 which engages in the drive device 7 in the closed position of the at least one actuating element 9, and / or an actuating element fastening device 25, wherein the at least one actuating element 9 can be fastened and / or is fastened to a part of the closing device 8, preferably to a base plate 13, via the actuating element fastening device 25, 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.

[0097] The operation of the spring devices 18 and the receiving devices 26 will be explained in more detail later.

[0098] The Figs. 22 to 41Figure 1 shows a second embodiment of an extension guide 1. The above applies analogously to this second embodiment, which is why only differences or further explanations will be discussed below.

[0099] Fig. 22 Figure 1 shows a perspective view of the second embodiment of an extension guide 1, wherein the extension guide 1 is shown in the extended position.

[0100] In contrast to the previous embodiment, the drive device 7 in this case has only a feed device 46 and a differently designed synchronization rod receiver 49.

[0101] Fig. 23 shows the detailed view I from Fig. 22 . In particular, the second variant of the synchronization rod receiver 49 can be seen.

[0102] Fig. 24 The detailed view J shows Fig. 22This detailed view of the second embodiment corresponds analogously to detailed view A of the previous embodiment in Fig. 6 .

[0103] Fig. 25 Figure 1 shows a perspective view of a further embodiment of an extension guide 1, wherein the extension guide 1 is shown in the retracted position.

[0104] Fig. 26 The detailed view K shows Fig. 25 This detailed view of the second embodiment corresponds analogously to detailed view B of the previous embodiment in Fig. 8 .

[0105] The Figs. 27 to 33 correspond analogously to the views of the previous embodiment in Figs. 9 to 19 .

[0106] Fig. 34 shows the interconnected assembly 14 and the synchronization rod receiver 49 of the second embodiment.

[0107] In this view, the extension guide 1 is in the retracted state, so that the synchronization rod receiver 49 is locked by the actuating element 9.

[0108] It should be noted that the engagement and / or release of the actuating element 9 can occur with any other part of the drive device 7. In the two embodiments described so far, the engagement and release take place between the actuating element 9 and the synchronization rod receptacle 49 of the drive device 7. It is equally conceivable that the engagement and release take place between the actuating element 9 and another part of the drive device 7 or at a different location within the drive device 7.

[0109] Fig. 35 The detailed view N shows Fig. 34 .

[0110] In the detailed view N of the Fig. 36 Actuator 9 is in the closed position. As in Fig. 35As can be clearly seen, the actuating element hook 24 of the actuating 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 actuating element 9 with the drive device 7 at at least one point of contact, preferably positively locking.

[0111] Fig. 36 Figure 1 shows a perspective view of the connected assembly 14 and the synchronization rod receiver 49 of the second embodiment, with the actuating element 9 in the release position.

[0112] Fig. 37 The detailed view O shows Fig. 36 .

[0113] In the detailed view O off Fig. 36 It can be seen that the actuating element hook 24 does not engage in the synchronization rod receiver 49 and does not block a relative movement of the rails 4,5.

[0114] Because the electric motor 31 is in contact with the eccentric 31 or motor actuator 40 in the Fig. 37 When the active agent 37 is in the position shown, one of the existing spring devices 18, namely the release spring device 57, can, by its spring force, push the part of the active agent 37, in whose area the release spring device 57 is arranged, away from the base plate 13. As a result, the active agent 37 can pivot in a rotational movement about the axis of rotation 23, thereby engaging the limiting device 38.

[0115] The limiting device 38 can be arranged at the end of the active agent 37 that is opposite the end of the active agent 37 in contact with the electric motor 31. The limiting device 38 can be provided by a receiving device 26, as shown in Fig. 37 through a recess 28, in contact with the actuating element 9.

[0116] By moving the actuating device 37, triggered by the release of the blockage of the motor actuator 40 and the spring force exerted by the release spring device 57, the limiting device 38 can move the actuating element 9 in the same pivoting direction in which the actuating device 37 itself moves. In this way, the actuating element 9 can be brought into the release position, which in Fig. 37 can be seen.

[0117] Fig. 38 shows another view of the connected assembly 14 and the synchronization rod receiver 49 of the second embodiment, with the actuating element 9 in the release position.

[0118] Fig. 39 The detailed view P shows Fig. 38 .

[0119] In the detailed view P from Fig. 38 It is easy to see how the actuator 9 can be moved into and / or held in the release position.

[0120] As already described, it can be provided that the actuating element 9 is pressed against the base plate 13 in its release position. In this way, it is possible that the actuating element hook 24 no longer engages in the drive device 7, as shown here in the synchronization rod receiver 49, but releases it, thus allowing the relative movement of the rails 4, 5, as shown here in the longitudinal direction 22.

[0121] The actuating element 9 is pressed against the base plate 13 by the limiting device 38, by the limiting device 38 being inserted into the receiving device 26, as shown in Fig. 39 represented by the recess 28, engages. When the active agent 37 is rotated counterclockwise, as shown in Fig. 39As shown, the actuating element is also pivoted in the same direction by the limiting device 38. The counterclockwise pivoting refers to a left-hand rotation about the axis of rotation 23. Fig. 39 .

[0122] It can be provided that a base plate 13 of the locking device 8 limits a movement of the at least one actuating element 9 in at least one direction.

[0123] The actuating element can be moved into the release position without the electric motor 31 and the active communication device 37 being involved, particularly in a triggering capacity. It can be provided that when the actuating element 9 is passed over by the synchronization rod sensor 49, by one of the existing rails, or by an actuator 19 connected to the rails, the actuating element 9 is displaced into the release position.

[0124] It can therefore be provided that the at least one actuating element 9 blocks a relative movement of the two rails 4, 5 in a closed position and allows it in a release position, wherein at least one spring device 18, as in Fig. 39 The closing spring device 58 is shown, which biases the at least one actuating element 9 into the closing position, wherein the at least one actuating 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 against the force exerted by the spring device 18.

[0125] As in Figs. 38 and 39As shown, 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 9. This illustrated embodiment is not to be understood as limiting, since any other actuator 19 connected to one of the two rails 4, 5 is conceivable.

[0126] This displacement of the actuator 9 can also lead to the release position of the actuator 9, as in Fig. 39 , however, the spring device 18, which is located between the actuating agent 37 and the actuating element 9, specifically the closing spring device 58, moves the actuating element 9 back into the closed position after it has been passed over.

[0127] It can therefore be provided that at least one actuating element 9, after its displacement during a further movement of the rail 4,5 or the actuator 19 associated therewith, is displaced by the spring device 18, as in Fig. 39 The closing spring device 58 is shown, which can be reset to the closed position.

[0128] Fig. 40 shows another view of the connected assembly 14 without the synchronization rod receiver 49 of the second embodiment, with the actuating element 9 in the closed position.

[0129] The base plate 13 may have at least one, preferably two, interfaces 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 attaching the base plate as a single, integrated unit 14 to one of the existing rails 4, 5, or 6, as described in more detail in the following figures.

[0130] Fig. 41 The detailed view Q shows 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.

[0131] Figure 42 shows a second rail 5 and a connected assembly 14 in the unconnected state.

[0132] Figure 43 shows a detailed view of R Figure 42 .

[0133] Detail view R shows the part of the base plate 13 that represents the base plate bolt 51, the base plate hook 52, the base plate slot 53, and the base plate stud 54. Next to it is shown the part of the second rail 5 that has the corresponding receiver devices for these features of the base plate 13.

[0134] 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 in Fig. 43 As shown, the respective connections between the base plate 13 and the second rail 5 can be made via detachable plug connections. Other detachable or non-detachable connections are also conceivable.

[0135] Figure 44shows the second rail 5 and the connected assembly 14 in the not yet fully connected state.

[0136] In the Fig. 44 The interconnected assembly 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 interfaces 17 of the base plate 13 and the rail 5 are in a disconnected state.

[0137] Figure 45 shows a detailed view S from Figure 44 .

[0138] 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. This allows the connected assembly 14 to be pivotally arranged relative to the second rail 5 via this plug connection. Thus, the connected assembly 14 can be pivoted towards the rail 5, and during the continuous rotation of the assembly 14 and the rail 5 relative to each other, the other 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 stud 54 with the base plate stud receiver 61, and the two interfaces 17 of the assembly 14 with the interfaces of the rail 5.

[0139] It can therefore be provided that one of the two rails 4,5 and a base plate 13 each have at least one interface 17 via which the base plate 13 can be attached and / or fastened to one of the two rails 4,5, wherein the interfaces 17 attached to each other form a non-destructively releasable positive locking and / or force locking.

[0140] The base plate slot 53 can be provided for the suspension of the base plate stud 54.

[0141] Figure 46 shows the second rail 5 and the connected assembly 14 in the fully connected state.

[0142] The Figs. 42 to 49The figures show the simple assembly of the interconnected component 14 onto one of the rails, specifically the second rail 5, of the extension guide 1. Assembly can be carried out at any time; that is, the component 14 can already be connected to the extension guide 1 before the extension guide is attached to furniture parts, or even afterward. Furthermore, the component 14 can also be easily removed from the extension guide 1, specifically the second rail 5, in reverse order. This offers the advantage of retrofitting, modifying, and / or replacing the interconnected component 14, either as a whole or in parts thereof, due to wear, damage, and / or further developments.

[0143] The Figs. 50 and 51 Figure 8 shows a third embodiment of a locking device. The above applies analogously to this embodiment of a locking device 8.

[0144] In contrast to the previous embodiments, Fig. 50and the exploded view in Fig. 51 , that the actuating element 9 is not pivoted orthogonally to the base plate 13, but that the pivoting movement takes place in a plane parallel to the base plate 13.
