PULL-OUT GUIDE

Description

The present application is a continuation of International Application PCT/AT2023/060418 filed on Dec. 1, 2023. Thus, all of the subject matter of International Application PCT/AT2023/060418 is incorporated herein by reference.

BACKGROUND OF THE INVENTION

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

Lockable pull-out guides, in particular for furniture, are known from the prior art in many different embodiments. However, the prior art has the disadvantage that locking mechanisms can be susceptible to faults. For example, it may happen that an adjusting element is unintentionally in a closed position and that an extended pull-out guide can no longer be brought into the retracted state.

It can also occur in the prior art that a switch detects the positions of the adjusting element and controls the closing device based thereon. In such a case, if the power supply to the closing device is interrupted, for example by a power failure or an empty battery, the closing device malfunctions and the pull-out guide can no longer be closed or opened.

A further disadvantage of the prior art is that locking devices take up space, as a result of which in particular the storage space of the furniture parts connected to the pull-out guide is adversely affected.

SUMMARY OF THE INVENTION

The object of the present invention is therefore to at least partially eliminate the disadvantages of the prior art and to provide an improved pull-out guide in comparison with the prior art, which is distinguished in particular by a construction which is less susceptible to faults and/or takes up less space. The object is also to provide a piece of furniture with such an improved pull-out guide.

In a first aspect, this object is achieved by a pull-out 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 one second rail to be connected to the second furniture part. The two rails are movably mounted relative to one another, and preferably a further rail is movably mounted between the two rails.

At least one closing device is provided with at least one electrically operable adjusting element, and the at least one adjusting element blocks a relative movement of the two rails in a closed position and permits said relative movement in a release position. At least one spring device is provided which biases the at least one adjusting element into the closed position, and the at least one adjusting element can be displaced into the release position by one of the two rails or by an actuator connected thereto during a movement in a first direction relative to the other rail counter to the force exerted by the spring device.

The spring device thus holds the adjusting element in its closed position. Only with a sufficiently strong force against the spring force of the spring device and only with a movement in a first direction of the one rail relative to the other rail can the adjusting element be displaced into the release position.

This results in the advantage of the pull-out guide that, independently of the position of the adjusting element, the two rails can always be brought into a maximum end position in a first direction relative to one another.

In a preferred embodiment, a displacement of the adjusting element can take place by the manual movement of one of the two rails in the first direction relative to the other rail, for example by closing a drawer of a piece of furniture by a person, before or when the two rails are retracted relative to one another. Subsequently, the adjusting element can be reset by the spring device and then prevent the rails from moving relative to one another in another direction. This reduces the susceptibility of the locking mechanism to malfunction.

In a second aspect, this object is achieved by a pull-out 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 one second rail to be connected to the second furniture part. The two rails are movably mounted relative to one another, preferably wherein a further rail is movably mounted between the two rails.

At least one closing device has at least one electrically operable adjusting element, and the at least one adjusting element blocks a relative movement of the two rails in a closed position and permits the relative movement in a release position. One of the two rails has at least one upper side to be connected to a lower side of the first furniture part, and the at least one closing device is aligned relative to the pull-out guide in such a way that the at least one adjusting element can be moved between the closed position and the release position transversely, preferably perpendicularly, 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 mounted on the closing device, preferably on a base plate of the closing device, so as to be pivotable about an axis of rotation.

The second aspect of the invention leads to a space saving of the closing device. For example, if the closing device is fastened by one of the two rails to a lower side of the first furniture part and the adjusting element is designed in accordance with the second aspect, the structural dimensions of the first furniture part and the storage space associated therewith can be better utilized, in particular in the longitudinal direction of the pull-out guide.

According to a preferred embodiment of the arrangement, at least one drive device is provided which has at least one energy accumulator, preferably the energy accumulator having at least one spring element. The at least one energy accumulator can be loaded by a relative movement of the two rails and/or can be released during 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 to a rail which is to be connected to a movable furniture part.

In a preferred embodiment variant, the spring element is a flexural spring and/or a torsion spring and/or a disk spring and/or a volute spring and/or an annular spring and/or a diaphragm spring, and the spring device consists at least partially of metal and/or plastic and/or a composite material.

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

DETAILED DESCRIPTION OF THE INVENTION

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 side. The uppermost drawer 43 of the four drawers 43 is shown in an open position, in which the rails 4, 5 and 6 are in a completely extended position, and the remaining three drawers 43 in a closed position. Due to the presence of the uppermost drawer 43 and the furniture body 44, the rails 4, 5 and 6 are not visible.

FIG. 2 shows the piece of furniture 42 from FIG. 1 in a perspective view, the top panel 47 of the furniture body 44 being hidden. As a result, the view on the pull-out guide 1 is free in a completely extended position of the rails 4, 5 and 6.

In contrast to FIG. 1, at least the second rail 5 of the pull-out guide 1 can be seen in this illustration, 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 releasable and/or non-releasable connection, for example a screw connection. The first rail 4 and a further rail 6 can be seen in the following illustrations.

It should be noted at this point that a pull-out guide 1 can be used for any type of furniture parts and is accordingly not limited to the exemplary 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 of FIG. 2 in a perspective side view. Due to the absence of the top panel 47, the view into the interior of the furniture 42 is free, specifically in that region in which the drawer is in the retracted state. A part of the pull-out guide 1 can thus be seen, this part being connected to the side panel 48. Due to the extended drawer 43, only the second rail 5, which is connected to the second furniture part 3, specifically to the side panel 48, can be seen of the pull-out guide 1.

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

FIG. 4 shows the piece of furniture 42 of FIG. 3, the uppermost drawer 43, i.e. the first furniture part 2 which is connected to the first rail 4, being hidden in this illustration. As a result, one of the two pull-out guides 1 is fully recognizable, while the second pull-out guide 1 is recognizable only to a limited extent, specifically only the extended first rail 4 and a part of the drive device 7.

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

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 lower side 20 on which the upper side 21 of the rail 10 connected to the movable furniture part 2, in this case the first rail 4, can be connected. In this exemplary 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 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 a lower side 20 of the first furniture part 2.

FIG. 5 shows the fully recognizable pull-out guide 1 from FIG. 4 in a perspective view. As shown in FIG. 5, a pull-out guide 1 can be provided, the pull-out guide 1 being provided for the movable mounting of a first furniture part 2 on a second furniture part 3, the pull-out guide comprising:

• • 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 movably mounted relative to each other, preferably wherein a further rail 6 is movably mounted between the two rails 4, 5,
  • at least one drive device 7, by means of which the two rails 4, 5 can be driven relative to one another.

However, the further rail 6 is to be provided only as an option; a pull-out guide 1 with only two rails is also conceivable.

The rails of the pull-out guide 1 are displaceable relative to one another. In other words, the rails of the pull-out guide 1 are telescopically displaceable. The rails of the pull-out guide 1 are shown in FIG. 5 in the fully extended position relative to one another.

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

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, there is the possibility of using 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 thus to 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 thus to bring the pull-out guide 1 into a retracted position.

Provision can be made for at least one, preferably a plurality of, load-transmitting rolling body to be 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 the at least one rolling body being mounted in at least one running carriage, and/or one of the two rails 4, 5 having at least one longitudinal profile on which the other of the two rails is mounted.

FIG. 6 shows a detailed view A of FIG. 5.

In this detailed view A, a part of the closing device 8, specifically the housing 35 and the adjusting element hooks 24 of the adjusting element 9, can be seen. The driver 12 can be seen next to it.

FIG. 7 shows the pull-out guide 1 of FIG. 4 in a perspective view, FIG. 7, in contrast to FIG. 4, shows the pull-out guide 1 in a completely retracted position. In other words, the first rail 4 and the second rail 5 are displaced relative to one another in such a way that they have the smallest longitudinal extent in the longitudinal direction 22.

As already described in FIG. 5, the drive device 7 can consist of an ejection device 45 as well as a retraction device 46. However, the number and embodiments of the drive devices 7 are not limited to this embodiment variant; other drive devices 7 are just as conceivable as a different number of drive devices 7.

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.

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 loaded by a relative movement of the two rails 4, 5 and/or can be released during a relative movement of the two rails 4,5, and/or the drive device 7 ks detachably fastenable 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.

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 also conceivable for the drive device 7 to be arranged on another 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 present in a simple screw connection, but other connections are also conceivable. Thus, the drive device fastening device 50 can represent both a releasable and a non-releasable connection, wherein releasable connections can be, for example, screw or plug connections and non-releasable connections can be, for example, soldered or riveted connections.

The drive device 7, specifically the ejection device 45, can have a synchronizing rod receiver 49. In this exemplary embodiment from FIGS. 1 to 4, the synchronizing rod receiver 49 is suitable for synchronizing opening and closing of the drawer 43 via a synchronizing rod with the second pull-out guide 1.

Provision can be made for the operative connection to be provided by a force transmission into at least one point of contact between the drive device 7 and the driver 12, wherein preferably the force transmission leads to an ejection of the drive device 7 from the driver 12.

FIG. 12 shows a detailed view D from FIG. 11.

In the detailed view D, the adjusting element hook 24 of the adjusting element 9 can be seen, since the latter projects out of a housing opening 36 of the housing 35. In contrast to the detailed view C, a larger proportion of the adjusting element hook 24 or of the adjusting element 9 can be seen here on account of the hidden drive device 7.

FIG. 13 shows the cohesive structural unit 14 or the closing device 8, FIG. 13 being an exploded view.

  • a bearing device 39, on which the at least one adjusting element 9 is mounted, preferably rotatably, preferably with the aid of an adjusting element fastening device 25 and/or together with an action transmitter 37, and/or
  • a spring device 18, which biases an action transmitter 37, which is arranged kinematically between the at least one adjusting element 9 and an electric motor 31, into a position in which the action transmitter 37 holds the at least one adjusting element 9 in the release position, wherein the action transmitter 37 can be moved by the electric motor 31 or a motor actuator 40 connected thereto into another position in which the action transmitter 37 does not hold the at least one adjusting element 9 in the release position.

The spring device 18 is not visible in FIG. 13, since it is covered by the action transmitter 37.

FIG. 14 shows the cohesive structural unit 14 or the closing device 8 from FIG. 11 from a different perspective. In contrast to FIG. 11, the housing 35 is hidden in FIG. 14. For this reason, the closing device 8 can thus be seen in its assembled state.

In FIG. 14, the adjusting element 9 is in its closed position. In FIGS. 14 to 21, the adjusting element 9 of this exemplary embodiment is shown continuous in its closed position. FIG. 15 is a detailed view E from FIG. 14.

In the detailed view E, the closing 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. The switch 34 can be connected to the base plate 13 via switch fastening devices 56.

The electric motor in FIG. 15 has an eccentric 32, any type of motor actuator 40 being suitable for indirect or direct actuation of the adjusting element 9, for example by the action transmitter 37. The electric motor 31 can actuate the adjusting element 9, wherein the electric motor 31 can be connected to the adjusting element 9 via an action transmitter 37. In addition, the action transmitter 37 can be operatively connected via spring devices 18 to the base plate 13 on the one hand and to the adjusting element 9 on the other hand. The spring devices 18 will be explained in more detail at a later time.

The other components of the adjusting element 9 and the components connected and/or in operative connection with the adjusting element 9 will be explained in more detail later.

The electric motor 31 is also connected to the action transmitter 37, which in turn is connected to the adjusting element 9.

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 switching rocker 55 due to the rotation of the eccentric. By means of the switch 34 and the control circuit 30, a signal can be generated which can be made available to the control circuit 30. The signal of the switch 34 can be transmitted directly or another signal derived therefrom can be transmitted by the control circuit via an electrical line and/or a wireless connection. Conversely, it can also be provided that signals are received by the control circuit via an electrical line and/or via a wireless connection and can subsequently control the electric motor 31.

A wireless connection can include all communication technologies, such as Bluetooth, NFC (near field communication), or other RFID (radio frequency identification) technologies.

• • 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 can be fastened and/or is fastened to a part of the closing device 8, preferably to a base plate 13, via the adjusting 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.

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

FIGS. 22 to 41 show a second exemplary embodiment of a pull-out guide 1. What has been said thus far applies analogously to this second exemplary embodiment, for which reason only differences or more detailed explanations will be provided below.

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

In contrast to the previous exemplary embodiment, the drive device 7 in this case has only one retraction device 46 and a synchronizing rod receiver 49 of a different design.

FIG. 23 shows the detailed view I from FIG. 22. The second variant of the synchronizing rod receiver 49 can be seen in particular.

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

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

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

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

FIG. 34 shows the cohesive structural unit 14 and the synchronizing rod receiver 49 of the second exemplary embodiment.

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

It should be noted at this point that the engagement and/or release of the adjusting element 9 can take place with any other part of the drive device 7. In the two previous embodiment variants, the engagement and release between the adjusting element 9 and the synchronizing rod receiving means 49 of the drive device 7 takes place. It is also conceivable for the engagement and release to 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 synchronizing 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 positively, by the contact of the at least one adjusting element 9 with the drive device 7 at at least one point of contact.

FIG. 36 shows a perspective view of the cohesive structural unit 14 and of the synchronizing rod receiver 49 of the second exemplary embodiment, the adjusting element 9 being in the release position.

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

In the detailed view O of FIG. 36, it can be seen that the adjusting element hook 24 does not engage in the synchronizing rod receiver 49 and does not block a relative movement of the rails 4, 5.

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 press away the part of the action transmitter 37 in the region of which the release spring device 57 is arranged from the base plate 13 by its spring force. As a result, the action transmitter 37 can pivot in a rotary movement about the axis of rotation 23, as a result of which the limiting device 38 is activated.

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 which is 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 in FIG. 37 by means of a recess 28.

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

FIG. 38 shows a perspective view of the cohesive structural unit 14 and of the synchronizing rod receiver 49 of the second exemplary embodiment, the adjusting element 9 being in the release position.

FIG. 39 shows the detailed view P from FIG. 38.

In the detailed view P of FIG. 38, it is easy to see how the adjusting element 9 can be brought into the release position and/or held therein.

As already described, the adjusting element 9 can be 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 releases it, whereby the relative movement of the rails 4, 5, as shown here, in the longitudinal direction 22, can be permitted.

The adjusting element 9 is pressed by the limiting device 38 against the base plate 13, 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 action transmitter 37 is pivoted counterclockwise, as shown in FIG. 39, the adjusting element is also pivoted in the same direction by the limiting device 38. In this case, the pivoting counterclockwise refers to a left-hand rotating movement about the axis of rotation 23 in FIG. 39.

A base plate 13 of the closing device 8 can limit a movement of the at least one adjusting element 9 in at least one direction.

The adjusting element can be brought into the release position without the electric motor 31 and the action transmitter 37 being involved, in particular in a triggering manner. When the adjusting 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 adjusting element 9 can be displaced into the release position.

Therefore, the at least one adjusting element 9 can block 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, in FIG. 39 the closing spring device 58, 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 against the force exerted by the spring device 18.

As illustrated in FIGS. 38 and 39, the synchronizing rod receiver 49 can be the actuator 19 connected to one of the two rails 4, 5. In this case, the synchronizing rod receiver 49 is connected to the first rail 4 via the drive device 9. This embodiment variant shown 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 in FIG. 39, but by means of the spring device 18, which is located between the action transmitter 37 and the adjusting element 9, specifically the closing spring device 58, the adjusting element 9 is moved back into the closed position again after it has passed over.

Therefore, the at least one adjusting element 9, after being displaced, can be returned to the closed position by the spring device 18, as shown in FIG. 39 by the closing spring device 58, when the rail 4, 5 or the actuator 19 connected thereto moves further.

FIG. 40 shows another view of the cohesive structural unit 14 without the synchronizing rod receiver 49 of the second exemplary embodiment, the adjusting element 9 being in the closed position.

The base plate 13 can have at least one, preferably two, interface 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 for fastening the base plate as a cohesive structural unit 14 to one of the existing rails 4, 5 or 6, which will be described in more detail in the following figures.

FIG. 41 shows the detailed view Q of 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 again shown in detail.

FIG. 42 shows a second rail 5 and a cohesive structural unit 14 in the unconnected state. FIG. 43 shows a detailed view R from FIG. 42.

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 knob 54. In addition, that part of the second rail 5 which has the corresponding receiver devices for these features of the base plate 13 is shown.

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 knobs 54 can be connected to the base plate knob 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 take place via detachable plug connections. Other detachable or fixed connections are also conceivable.

FIG. 44 shows the second rail 5 and the cohesive structural unit 14 in the not yet completely connected state.

In FIG. 44, the cohesive structural unit 14 is connected only via one point, specifically via the base plate bolt 51 of the base plate 13 in connection 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.

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

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 cohesive structural unit 14 to be arranged pivotably relative to the second rail 5 via this plug connection as a pivot point. Thus, the cohesive structural unit 14 can be pivoted in the direction of the rail 5, and in the course of the continuous rotary movement of the structural unit 14 and the rail 5 with respect 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 knobs 54 with the base plate knobs receiver 61 and the two interfaces 17 of the structural unit 14 with the interfaces of the rail 5.

Therefore, 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, the interfaces 17 fastened to one another forming a non-destructively releasable form fit and/or force fit.

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 can be provided for the spring suspension of the base plate knob 54.

FIG. 46 shows the second rail 5 and the cohesive structural unit 14 in the completely connected state.

FIGS. 42 to 49 show the simple assembly of the cohesive structural unit 14 on one of the rails, specifically the second rail 5, of the pull-out guide 1. The assembly can take place at any time, that is to say the structural unit 14 can already be connected to the pull-out guide 1 before the pull-out guide is fastened to furniture parts or else afterwards. In addition, the structural unit 14 can also be easily removed again from the pull-out guide 1, specifically the second rail 5, in the reverse order. This offers the advantage of retrofitting, converting and/or replacing the cohesive structural unit 14 as a whole or parts thereof as a result of wear, damage and/or further developments.

FIGS. 50 and 51 show a third exemplary embodiment of a closing device 8. What has been said thus far applies analogously to this embodiment variant 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 that the pivoting movement extends in a plane parallel to the base plate 13.
