Description

[0001] From pull guide

[0002] The present invention relates to a pull-out guide according to the preamble of claim 1 and to a piece of furniture with such a pull-out guide.

[0003] Lockable pull-out guides, particularly for furniture, are known in many different designs. However, the current state of the art has the disadvantage that locking mechanisms can be prone to failure. For example, it can happen that an actuator is inadvertently in a closed position, making it impossible to return an extended pull-out guide to the retracted position.

[0004] Even with current technology, a switch can detect the positions of the actuator and control the locking device based on this. If the locking device's power supply fails in such a case, for example, due to a power outage or a dead battery, the locking device malfunctions, and the pull-out guide can no longer be opened or closed.

[0005] A further disadvantage of the state of the art is that locking devices take up space, which has a negative impact on 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 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 less fault-prone and / or less space-consuming design. The object is further to provide a piece of furniture with such an improved pull-out guide.

[0007] This object is achieved by the features of claims 1, 2 and 18.

[0008] In a first aspect, this object is achieved by means of a pull-out guide according to claim 1, namely by a pull-out guide for the movable mounting of a first furniture part on a second furniture part with

[0009] - 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 one another, 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 actuable actuating element is provided, wherein the at least one actuating element blocks a relative movement of the two rails in a closed position and permits it in a release position, wherein at least one spring device is provided which pretensions the at least one actuating element into the closed position, wherein the at least one actuating element can be displaced into the release position by one of the two rails or an actuator connected thereto during a movement in a first direction relative to the other rail against the force exerted by the spring device.

[0010] The spring mechanism therefore holds the actuator in its closed position. Only with a sufficiently strong force counteracting the spring force of the spring mechanism and only with a movement in a first direction of one rail relative to the other rail can the actuator be displaced into the release position.

[0011] This results in the advantage of the pull-out guide that, regardless of the position of the adjusting element, the two rails can always be brought into a maximum end position relative to each other in a first direction.

[0012] In a preferred embodiment, it can be provided that the manual movement of 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, displaces the adjusting element before or when the two rails have been retracted relative to one another. Following this, the adjusting element can be reset by the spring device and then prevent the rails from moving relative to one another in a different direction. This reduces the susceptibility of the locking mechanism to failure.

[0013] In a second aspect, this object is achieved by means of a pull-out guide according to claim 2, namely by a pull-out guide for the movable mounting of a first furniture part on a second furniture part with

[0014] - 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 one another, preferably wherein a further rail is mounted so as to be movable between the two rails, wherein at least one locking device is provided with at least one electrically actuated actuating element, wherein the at least one actuating element blocks a relative movement of the two rails in a closed position and permits it in a release position, wherein one of the two rails has at least one upper side to be connected to an underside of the first furniture part, wherein the at least one locking device is aligned relative to the pull-out guide in such a way that the at least one actuating element is transversely, preferably vertically, between the closed position and the release position,to a longitudinal direction of the pull-out guide and in the direction of the upper side of the rail, wherein the at least one adjusting element is pivotally mounted about a rotation axis on the locking device, preferably on a base plate of the locking device.

[0015] The second aspect of the invention results in a space saving of the locking device. For example, if the locking device is attached to an underside of the first furniture part by one of the two rails and the adjusting element is designed according to the second aspect, the structural dimensions of the first furniture part and the associated storage space can be better utilized, particularly in the longitudinal direction of the pull-out guide.

[0016] Further advantageous embodiments of the arrangement are defined in the dependent claims.

[0017] According to a preferred embodiment of the arrangement, it is provided that the at least one drive device has at least one energy accumulator, preferably wherein the energy accumulator has at least one spring element, wherein the at least one energy accumulator can be charged by a relative movement of the two rails and / or discharged during a relative movement of the two rails, and / or the drive device can be detachably fastened and / or fastened to one of the two rails, preferably to a rail which is to be connected to a movable furniture part.

[0018] In a preferred embodiment, it can be provided that the spring element is a spiral spring and / or a torsion spring and / or a disc spring and / or an evolute spring and / or an annular spring and / or a diaphragm spring, wherein the spring device consists at least partially of metal and / or plastic and / or a composite material.

[0019] Furthermore, protection is sought for a piece of furniture having at least a first and a second furniture part and at least one pull-out guide according to the invention, wherein 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 wherein the first furniture part is designed as a drawer and the second furniture part as a furniture body.

[0020] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings, in which:

[0028] Closing device of the second embodiment of the pull-out guide from Fig. 22 to 26, partially with the actuator of the drive device from Fig. 22 to 26;

[0029] Fig. 42 to 49: different views of the second rail from

[0030] Fig. 1 to 8 and the base plate from Fig. 1 to 21, Fig. 50 to 51: two views of a further embodiment of a locking device.

[0031] Fig. 1 shows a perspective view of a piece of furniture 42, 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 topmost 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 are shown in a closed position. Due to the topmost drawer 43 and the furniture body 44, the rails 4, 5, and 6 cannot be seen.

[0032] Fig. 2 shows the 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 in a fully extended position of the rails 4, 5, and 6.

[0033] In contrast to Fig. 1, this illustration shows at least the second rail 5 of the pull-out guide 1, with the second rail 5 being 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 shown in the following figures.

[0034] At this point, it should be noted that a pull-out guide 1 can be used for any type of furniture part and is therefore not limited to the exemplary embodiments presented 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 a stationary furniture part, specifically a furniture body 44. However, a pull-out guide 1 is not limited to drawers and furniture bodies.

[0035] Fig. 3 shows the furniture from Fig. 2 in a perspective side view. The absence of the top panel 47 provides a clear view of the interior of the furniture 42, specifically the area where the drawer is in the retracted state. Thus, part of the pull-out guide 1 is visible, which is connected to the side panel 48. Because the drawer 43 is extended, 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.

[0036] As shown in Fig. 2 and 3, a piece of furniture 42 is provided, wherein the piece of furniture 42 is provided with at least a first and a second furniture part 2, 3 and at least one pull-out guide 1 according to the invention, wherein 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 as a furniture body 44.

[0037] Fig. 4 shows the furniture 42 from Fig. 3, with the top drawer 43, i.e., the first furniture part 2, which is connected to the first rail 4, hidden in this illustration. Consequently, one of the two existing 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 device 7.

[0038] As shown in Fig. 4, the pull-out guides 1 each consist of a first rail 4, a second rail 5, and an additional 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.

[0039] As can be seen from Figs. 3 and 4, the first furniture part 2, for example in the form of a drawer 43 or a movable furniture part 16, can have a bottom side 20 to which the top side 21 of the rail 10 connected to the movable furniture part 2, here the first rail 4, can be connected. The rail 15 connected to the immovable furniture part is connected to the furniture body 44 in this embodiment and is the second rail 5.

[0040] As can be seen from Figs. 3 and 4, it can be provided that the pull-out guide 1 is designed as an underfloor guide and can preferably be arranged on an underside 20 of the first furniture part 2.

[0041] Fig. 5 shows the fully visible pull-out guide 1 from Fig. 4 in a perspective view.

[0042] As shown in Fig. 5, a pull-out guide 1 can be provided, wherein the pull-out guide 1 for the movable mounting of a first furniture part 2 on a second furniture part 3 with:

[0043] - a first rail 4 to be connected to the first furniture part 2 and at least one second rail 5 to be connected to the second furniture part 3, wherein the two rails 4, 5 are mounted so as to be movable relative to one another, preferably wherein a further rail 6 is mounted so as to be movable between the two rails 4, 5,

[0044] - at least one drive device 7, with which the two rails 4, 5 can be driven relative to each other. The additional rail 6, however, is only optional; a pull-out guide 1 with only two rails is also conceivable.

[0045] The rails of the pull-out guide 1 are movable relative to one another. In other words, the rails of the pull-out guide 1 are telescopically movable. The rails of the pull-out guide 1 are shown in Fig. 5 in the fully extended position relative to one another.

[0046] In addition to the existing rails 4, 5 and 6, the pull-out guide 1 has a drive device 7 and a locking device 8.

[0047] The drive device 7 can be used to drive the existing rails of the pull-out guide 1 relative to one another. As shown in Fig. 5, it is possible to use an ejection device 45 and / or a retraction device 46.

[0048] An ejection device 45 serves to extend the first rail 4 relative to the second rail 5 and thus to bring the pull-out guide 1 into an extended position.

[0049] The retraction device 46 serves to retract the first rail 4 relative to the second rail 5 and thus to bring the pull-out guide 1 into a retracted position.

[0050] It can be provided that at least one, preferably several, load-transmitting rolling elements are arranged 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, 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. 6 shows a detailed view A from Fig. 5.

[0051] In this detailed view A, a part of the locking device 8, specifically the housing 35 and the actuating element hook 24 of the actuating element 9, can be seen. The driver 12 can be seen next to it.

[0052] Fig. 7 shows the pull-out guide 1 from Fig. 4 in a perspective view, wherein in Fig. 7, in contrast to Fig. 4, the pull-out guide 1 is shown in a fully retracted position. In other words, this means that the first rail 4 and the second rail 5 are displaced relative to one another such that they have the smallest longitudinal extent in the longitudinal direction 22.

[0053] As already described in Fig. 5, the drive device 7 can consist of both an ejection device 45 and a feed device 46. However, the number and embodiments of the drive devices 7 are not limited to this embodiment; other drive devices 7 are just as conceivable as a different number of drive devices 7.

[0054] It can be provided that the at least one drive device 7 is designed as an ejection device 45, wherein one of the two rails 4, 5 can be ejected by the ejection device 45, starting from a first position in which the two rails 4, 5 are retracted relative to one another, in the direction of a second position in which the two rails 4, 5 are extended relative to one another in the longitudinal direction 22, and / or wherein the at least one drive device 7 is designed as a retraction device 46, wherein one of the two rails 4, 5 can be retracted by the retraction device 46, starting from a second position in which the two rails 4, 5 are extended relative to one another, in the direction of a first position in which the two rails 4, 5 are retracted relative to one another in the longitudinal direction 22.

[0055] It can be provided that the at least one drive device 7 has at least one energy accumulator, preferably wherein the energy accumulator has at least one spring element, wherein the at least one energy accumulator can be charged by a relative movement of the two rails 4, 5 and / or discharged during a relative movement of the two rails 4, 5, and / or the drive device 7 can be detachably fastened and / or fastened to one of the two rails 4, 5, preferably to a rail 10 which is to be connected to a movable furniture part 11.

[0056] As shown in Fig. 7, the drive device 7 can be connected to the first rail 4 via drive device fastening devices 50. However, it is equally conceivable for the drive device 7 to be arranged on a different part of the pull-out guide 1 and / or on one of the existing furniture parts. The drive device fastening device 50 can, as shown here, be a simple screw connection, but other connections are also conceivable. For example, the drive device fastening device 50 can represent both a detachable and a non-detachable connection, wherein detachable connections can be, for example, screw or plug connections and non-detachable connections can be, for example, soldered or riveted connections.

[0057] The drive device 7, specifically the ejection device 45, can have a synchronization rod receiver 49. In this exemplary embodiment from Figs. 1 to 4, the synchronization rod receiver 49 is suitable for synchronizing the opening and closing of the drawer 43 with the second pull-out guide 1 via a synchronization rod. In Fig. 7, the locking device 8 is arranged below the drive device 7, of which only the housing 35 is visible in the view shown.

[0058] Fig. 8 shows the detailed view B from Fig. 7.

[0059] As shown in the detailed view B, it can be provided that at least one locking device 8 is provided with at least one electrically actuated actuating element 9, wherein the at least one actuating element 9 engages in the drive device 7 in a closed position and releases the drive device 7 in a release position.

In addition to the ejection device 45, the retraction device 46 can be seen, wherein the drive device 7, consisting of the ejection device 45 and the retraction device 46, is attached to the first rail 4.

[0061] Fig. 9 shows a perspective view of a connected structural unit 14 and the drive device 7 from Figs. 5 to 8.

[0062] In Fig. 9, several parts of the pull-out guide 1 are hidden; only the locking device 8 and the driver 12, both arranged on the base plate 13, as well as the drive device 7 are shown. However, the driver 12 cannot be seen because the drive device 7 covers it.

[0063] As shown in Fig. 9, it can be provided that the base plate has 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 knob 54. These features can be provided to fasten the base plate together with the locking device 8 and the driver 12 as a coherent structural unit 14 to one of the existing rails. Further explanations of this can be found in Figs. 42 to 49.

[0072] In the detailed view D, the adjusting element hook 24 of the adjusting element 9 can be seen, as it protrudes from a housing opening 36 of the housing 35. In contrast to the detailed view C, a larger portion of the adjusting element hook 24 or the adjusting element 9 can be seen here due to the hidden drive device 7.

[0073] Fig. 13 shows the connected structural unit 14 or the locking device 8, wherein Fig. 13 is an exploded view.

[0074] As can be clearly seen in Fig. 13, it can be provided that the base plate 13 is made of two parts. In principle, the base plate 13 can also consist of one part or of several parts.

[0086] The spring device 18 cannot be seen in Fig. 13 because it is covered by the active agent 37.

[0087] Fig. 14 shows the connected structural unit 14 or the locking device 8 from Fig. 11 from a different perspective.

[0088] In Fig. 14, in contrast to Fig. 11, the housing 35 is hidden. For this reason, the locking device 8 can be seen in its assembled state.

[0089] The actuating element 9 is in its closed position in Fig. 14. In Figs. 14 to 21, the actuating element 9 of this embodiment is shown in its closed position throughout.

[0090] Fig. 15 is a detailed view E from Fig. 14. In the detailed view E, the locking device 8 can be seen in the assembled state. The electrical line 33 supplies the control circuit 30 and the electric motor 31 connected to the control circuit 30. Between the electric motor 31 and the control circuit 30 there is a switch 34 which is in contact with the electric motor 31 via a rocker switch 55.

[0091] The electric motor in Fig. 15 has an eccentric 32, wherein any type of motor actuator 40 is suitable for the indirect, i.e. indirect, for example, actuation via the operative intermediary 37, or direct actuation of the actuating element 9. The electric motor 31 can actuate the actuating element 9, wherein the electric motor 31 can be connected to the actuating element 9 via an operative intermediary 37. The operative intermediary 37 can also be operatively connected via spring devices 18 to the base plate 13 on the one hand and the actuating element 9 on the other hand. The spring devices 18 will be explained in more detail later.

[0092] The other components of the actuating element 9 and the components connected to the actuating element 9 and / or in operative connection will be explained in more detail later.

[0095] The detailed view F shows a section of the base plate 13, wherein primarily the base plate bolt 51, the base plate hook 52, the base plate slot 53, the base plate knob 54 and the interfaces 17 can be seen. These features are explained in more detail in Figs. 42 to 49. In addition to these features, the driver 12, a part of the actuating element 9 and the limiting device 38 can also be seen. The limiting device 38 serves to limit the movement of the actuating element 9 in at least one direction.

Next to it is the switch 34, which is fastened to the base plate 13 via switch fastening devices 56. Next to the switch 34 is the electric motor 31, which is connected to the switch 34 via a rocker switch 55. The electric motor 31 is also connected to the actuator 37, which in turn is connected to the actuating element 9.

[0100] Since the electric motor 31, as shown in Fig. 19, can be an electric motor with an eccentric 32, the switch 34 can detect the position of the eccentric via the rocker switch 55 due to the rotation of the eccentric. A signal can be generated by the switch 34 and the control circuit 30, which can be made available to the control circuit 30. The signal from the switch 34 can be sent directly or another signal derived therefrom from the control circuit via an electrical line and / or a wireless connection. Conversely, it can also be provided that signals from the control circuit are received via an electrical line and / or a wireless connection and subsequently the electric motor

[0101] 31 can control .

[0111] Fig. 20 shows the front view of the connected unit

[0112] 14 or the locking device 8 from Fig. 18.

[0113] In the view of the connected structural unit 14 in Fig. 20, the driver 12, the actuating element 9, the active agent 37, the electric motor 31, the rocker switch 55, the switch 34 and the control circuit 30 on the base plate 13 can be seen from left to right, wherein the electrical line 33 runs from the control circuit 30 to the right.

[0114] It can be provided that an energy interface 41 is provided for connecting to a spatially 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 locking device 8.

[0115] The energy interface 41 can be part of the control circuit 30 and / or the electrical line 33.

[0116] As shown in Fig. 20, the electrical line 33 can have an energy interface 41, via which the energy supply to the pull-out guide 1, in particular the locking device 8, is enabled, wherein the energy interface 41 is shown only schematically in Fig. 20.

[0117] Fig. 21 shows the detailed view H from Fig. 20.

[0118] It can be provided, as shown in the detailed view H in Fig. 21, that the at least one adjusting element 9, in particular in the form of a substantially elongated component, has:

[0119] - 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

[0120] - an adjusting element fastening device 25, wherein the at least one adjusting element 9 can be fastened and / or is fastened to a part of the locking device 8, preferably to a base plate 13, via the adjusting element fastening device 25, and / or

[0121] - 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.

[0122] The functioning of the spring devices 18 and the

[0123] Receiving devices 26 will be explained in more detail later.

[0124] Figs. 22 to 41 show a second embodiment of a pull-out guide 1. What has been said so far applies analogously to this second embodiment, which is why only differences or more detailed explanations are discussed below.

[0125] 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.

[0126] In contrast to the previous embodiment, the drive device 7 in this case has only one retraction device 46 and a differently designed synchronization rod receiver 49.

[0127] Fig. 23 shows the detailed view I from Fig. 22. In particular, the second variant of the synchronization rod receiver 49 can be seen.

[0128] 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.

[0129] Fig. 25 shows a perspective view of the further

[0130] Embodiment of a pull-out guide 1, wherein the pull-out guide 1 is shown in the retracted position.

[0131] 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.

[0132] Fig. 34 shows the connected assembly 14 and the synchronization rod receiver 49 of the second embodiment.

[0133] In this view, the pull-out guide 1 is in the retracted state, so that the synchronization rod receiver 49 is locked by the actuating element 9.

[0134] At this point, 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 previous embodiments, the engagement and release takes place between the actuating element 9 and the synchronization rod holder 49 of the drive device 7. It is also conceivable for the engagement and release to take place between the actuating element 9 and another part of the drive device 7 or at another location on the drive device 7.

[0135] Fig. 35 shows the detailed view N from Fig. 34.

[0136] In the detailed view N of Fig. 36, the actuating element 9 is in the closed position. As can be clearly seen in Fig. 35, 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, preferably in a form-fitting manner, by the contact of the at least one actuating element 9 with the drive device 7 at at least one point of contact. Fig. 36 shows a perspective view of the connected structural unit 14 and the synchronization rod receiver 49 of the second exemplary embodiment, with the actuating element 9 in the release position.

[0137] Fig. 37 shows the detailed view 0 from Fig. 36.

[0138] In the detailed view 0 of Fig. 36 it can be seen that the adjusting element hook 24 does not engage in the synchronization rod receiver 49 and does not block a relative movement of the rails 4, 5.

[0139] Because the electric motor 31 with the eccentric 31 or motor actuator 40 is in the position shown in Fig. 37, one of the existing spring devices 18, namely the release spring device 57, can, through its spring force, push that part of the active agent 37, in the region of which 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 rotation axis 23, whereby the limiting device 38 is activated.

[0140] The limiting device 38 can be arranged at that end of the active agent 37 which is opposite the end of the active agent 37 in contact with the electric motor 31. The limiting device 38 can be in contact with the actuating element 9 through a receiving device 26, as in Fig. 37 through a recess 28.

[0141] By moving the active mediator 37, triggered by the released 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 active mediator 37 itself moves. In this way, the actuating element 9 can be brought into the release position, which can be seen in Fig. 37.

[0142] Fig. 38 shows another view of the connected assembly 14 and the synchronization rod receiver 49 of the second embodiment, wherein the actuating element 9 is in the release position.

[0143] Fig. 39 shows the detailed view P from Fig. 38.

[0144] In the detailed view P of Fig. 38 it is clearly visible how the actuating element 9 can be brought into the release position and / or held.

[0145] As already described, it can be provided that the adjusting element 9 is pressed against the base plate 13 in its release position. In this way, it is possible for the adjusting element hook 24 to no longer engage with the drive device 7, as shown here in the synchronization rod receiver 49, but to release it, thus permitting the relative movement of the rails 4, 5, as shown here in the longitudinal direction 22.

[0146] The actuating element 9 is pressed against the base plate 13 by the limiting device 38, in that the limiting device 38 engages in the receiving device 26, as shown in Fig. 39 in the form of the recess 28. When the effector 37 is pivoted counterclockwise, the limiting device 38 also

[0147] Adjusting element pivoted in the same direction. Counterclockwise pivoting refers to a left-handed movement about the rotation axis 23 in Fig. 39. It can be provided that a base plate 13 of the locking device 8 limits the movement of the at least one adjusting element 9 in at least one direction.

[0148] The actuating element can be moved into the release position without the electric motor 31 and the actuator 37 being involved, in particular without triggering them. It can be provided that when the actuating element 9 is moved over by the synchronization rod receiver 49 or 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.

[0149] It can 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 permits it in a release position, wherein at least one spring device 18, as shown in Fig. 39 the closing spring device 58, is provided, which pretensions 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 against the force exerted by the spring device 18.

[0150] As shown in Fig. 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 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. This displacement of the actuating element 9 can also lead to the release position of the actuating element 9, as in Fig. 39, but the spring device 18, which is located between the action mediator 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.

[0151] It can therefore be provided that the at least one actuating element 9, after its displacement, can be reset into the closed position by the spring device 18, as shown in Fig. 39 by the closing spring device 58, upon further movement of the rail 4, 5 or the actuator 19 connected thereto.

[0152] Fig. 40 shows another view of the connected assembly 14 without the synchronization rod receiver 49 of the second embodiment, wherein the actuating element 9 is in the closed position.

[0153] The base plate 13 may be provided with 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 to attach the base plate as a coherent structural unit 14 to one of the existing rails 4, 5, or 6, which is described in more detail in the following figures.

[0154] Fig. 41 shows the 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 knob 54 are shown in detail.

[0155] Figure 42 shows a second rail 5 and a connected assembly 14 in the unconnected state. Figure 43 shows a detailed view R from Figure 42.

[0156] The detailed view R shows that part of the base plate 13 which 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 that part of the second rail 5 which has the corresponding receiver devices for these features of the base plate 13.

[0157] In this case, it can be provided that the base plate bolt 51 can be connected to the base plate bolt receiver 59, the base plate hook 52 can be connected to the base plate hook receiver 60, and / or the base plate stud 54 can be connected to the base plate stud receiver 61. As shown in Fig. 43, it can 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.

[0158] Figure 44 shows the second rail 5 and the connected structural unit 14 in the not yet fully connected state.

[0159] In Fig. 44, the interconnected structural unit 14 is connected at only 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 an unconnected state.

[0160] Figure 45 shows a detailed view S from Figure 44 .

[0161] The detailed 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 one another via a plug connection. In this way, it is possible for the connected structural unit 14 to be arranged such that it can be pivoted relative to the second rail 5 via this plug connection as a pivot point. The connected structural unit 14 can therefore be pivoted in the direction of the rail 5, wherein in the course of the ongoing rotary movement of the structural unit 14 and the rail 5 relative to one another, the other connecting elements can also come into contact with one another, 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 structural unit 14 with the interfaces of the rail 5.

[0162] 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 fastened and / or is fastened to one of the two rails 4, 5, wherein the interfaces 17 fastened to one another form a form-fitting connection and / or force-fitting connection which can be released without destruction.

[0163] The base plate slot 53 can be provided for the springing of the base plate knob 54.

[0164] Figure 46 shows the second rail 5 and the connected structural unit 14 in the fully connected state.

[0165] Figs. 42 to 49 show the simple assembly of the interconnected structural unit 14 to one of the rails, specifically the second rail 5, of the pull-out guide 1. Assembly can take place at any time, i.e. the structural 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. Furthermore, the structural unit 14 can also be easily removed from the pull-out guide 1, specifically the second rail 5, in the reverse order. This offers the advantage of being able to retrofit, convert and / or replace the interconnected structural unit 14 as a whole or parts thereof due to wear, damage and / or further developments.

[0166] Figures 50 and 51 show a third embodiment of a locking device 8. What has been said so far applies analogously to this

[0167] Design variant of a locking device 8 .

[0168] 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 the

[0169] Pivoting movement in a plane parallel to the base plate 13.
