Description

The invention relates to an arrangement of a first pull-out guide for a movable furniture part and a driver for a drive device for moving the movable furniture part relative to a furniture body, the driver having a driver projection which can be brought into operative connection with the drive device, with a first fastening device a part arranged on the driver and a part arranged on the pull-out guide is provided, with which the driver can be fastened to the first pull-out guide, part of the first fastening device being designed as a pin and part as a pin receptacle corresponding to the pin, the pin being inclined is placed for the longitudinal extension of the first pull-out guide and the pin receptacle has an insertion channel having a narrow point for the pin. In addition, the invention relates to a piece of furniture with such an arrangement and a method for attaching a driver of such an arrangement to a pull-out guide of such an arrangement.

In the furniture fittings industry, drive devices with which a movement of a movable furniture part is mechanically supported have been known for many years. For this purpose, ejection devices in the form of so-called touch-latch mechanisms or pull-in devices are known. These drive devices are usually arranged on the furniture body or on the movable furniture part. Such drive devices cooperate with a driver which z. B. with a drive device arranged on the movable furniture part is assigned to the furniture body or a body rail of a pull-out guide.

A generic arrangement is based on the Figures 1 to 10 of the WO 2016/000003 A1 emerged. This shows a driver which can be brought from a release position into a fixing position with the rail by a fastening movement, the fastening movement taking place in a horizontal plane. In other words, in this case the drive device is arranged on the underside of a drawer bottom or is connected to the drawer rail and can be brought into operative connection with the driver attached to the body rail. The driver has a driving pin.

For the attachment of the driver to the rail, a first connecting piece is provided which protrudes vertically from the plate-shaped base region of the driver. This first connecting piece has a neck area in the form of a cylinder with a substantially square base. A second and a third connecting piece are bent or punched out of the retaining plate of the driver. In the case of a fastening movement along a straight line when the driver is pushed into the rail, the neck area of the driver fits exactly through a narrow point that forms the counterpart connection on the rail. As soon as the pre-assembly position is reached after this insertion, the second part of the fastening movement takes place in the horizontal plane by a pivoting movement about the vertical axis formed by the first connecting piece. At the end of this pivoting movement, the second connection piece comes into frictional connection with the second connection counterpart and the third connection piece also comes into frictional connection with the third connection counterpart, whereby the fixing position is reached. This pivoting fastening movement is advantageous in itself, since it can be carried out relatively simply and easily even with pull-out guides that have already been installed. In addition, there is a secure connection via the neck area that fits through the constriction and the subsequent pivoting.

The disadvantage of this embodiment, however, is that a driver that is mirror-inverted to the other side of the pull-out guide must be used for one side of a pull-out guide. This means that two different drivers per drawer must be provided. As a result, the production effort is higher. Storage is also practically doubled.

In contrast, they show Figures 11 to 13 of the WO 2016/000003 A1 a driver in which a purely linear fastening movement is given. In this variant, connecting counterparts in the form of U-shaped tabs are formed on the underside of the rail. These counterparts form guide elements for the driver. Slightly bent connecting pieces are formed on the retaining plate of the driver. By pushing in the driver during the fastening movement, the slightly bent connecting pieces get between the connecting counterparts and the underside of the rail. This is the Fixed position reached without pivoting. A ribbed surface is formed on the underside of the counterpart connection piece and on the top side of the connection piece. These ribbed surfaces interlock or interlock with one another, so that a form-fitting hold between the driver and the rail is guaranteed. A disadvantage of this design is on the one hand that both connecting pieces have to be threaded into the tabs at the same time when fastening, which can lead to problems given the limited space required and the confusion in the area of the drawer. On the other hand, it is disadvantageous that as a result of the hooking over the ribbed surfaces, subsequent loosening is practically impossible without destruction. For such a release, the tab has to be spread open or the slightly bent connecting piece has to be pressed down somehow with external force so that the individual hooks can be released from one another. So they show Figures 11 to 13 of this document only one variant for a one-time fastening of the driver.

The object of the present invention is to create an arrangement which is improved over the prior art. In particular, the attachment should be as simple, uncomplicated and secure as possible. In addition, double storage should be avoided. In addition, the driver should be able to be attached and detached again as simply as possible.

This is achieved by an arrangement having the features of claim 1. Accordingly, it is provided according to the invention that the driver has a part of a second fastening device designed as a pin or a pin receptacle for optionally attaching the driver to a second pull-out guide, which is essentially designed as a mirror image of the first pull-out guide, and that the part arranged on the driver of the first Fastening device is arranged mirror-symmetrically to the part of the second fastening device arranged on the driver on the driver.

As a result of the second fastening device, which is designed mirror-symmetrically to the first fastening device on the driver, the same driver can be fastened to a second pull-out guide on the opposite side via this second fastening device. Thus, two can essentially Identical drivers are used, one driver being fastened to the first pull-out guide via a first fastening piece and the other driver being fastened to the second pull-out guide via the part of the second fastening device. This means that no double storage is necessary. In addition, an easily detachable fastening is provided via the pin and the pin receptacle. The possible pivoting movement also simplifies the fastening process.

The arrangement according to claim 1 also does not result in an obvious manner from a combination of the two exemplary embodiments of WO 2016/000003 A1 . Theoretically, a person skilled in the art could indeed use the two bent up connecting pieces of the Figures 11 to 13 by in each case a first connector of the exemplary embodiment according to FIGS Figures 1 to 10 replace. However, this would not result in a secure connection, since a pivoting movement for a form-fitting hold is absolutely necessary for the first connecting pieces with the neck area and the corresponding constriction. So if - as in the Figures 11 to 13 the linear fastening movement takes place, theoretically arranged first connecting pieces could not be fastened to the neck area in a form-fitting manner.

Preferred embodiments of the present invention are given in the dependent claims.

Basically, there are two alternative training options with regard to the pin and the pin receptacle. According to a first variant, it is therefore provided that the parts of the first fastening device and the second fastening device formed on the driver are designed as pins and the pin receptacle is arranged on the pull-out guide. Conversely, as a second variant, it can be provided that the parts of the first fastening device and the second fastening device formed on the driver are designed as pin receptacles and the pin is arranged on the pull-out guide.

All of the examples and more detailed definitions of the journal and the journal receptacle cited in this application apply in each case regardless of where the journal and where the journal receptacle are arranged. This means that if the pin is described in relation to an arrangement on the driver, then this also applies - as long as it is logically meaningful in reverse for an arrangement of the pin on the pull-out guide. The fastening movement described also applies analogously to both design variants.

It is preferably provided that parts of exactly two fastening devices (namely the first fastening device and the second fastening device) are formed on the driver.

It is preferably also provided that only one pin or one pin receptacle is arranged on the pull-out guide. That is, a part of exactly one fastening device is formed on the pull-out guide.

Since only part of the two fastening devices arranged on the driver fulfills a function in the assembled state, it is preferably provided that in the assembled state of the arrangement the part of the second fastening device arranged on the driver is spaced from the part of the fastening device arranged on the pull-out guide. This means that the pin or the pin receptacle of the second fastening device has no function or connection to the respective pull-out guide.

The driver can be designed as desired as long as it has the driver projection and the two parts of the first fastening device and the second fastening device.

According to a preferred embodiment it is provided that the driver has a base plate. This base plate is preferably designed as a sheet metal. This sheet preferably has an essentially regular sheet thickness. This sheet metal thickness is between 0.5 mm and 1.5 mm and is preferably between 0.7 mm and 1.0 mm. Specifically, a sheet thickness of 0.8 mm is intended.

In a similar manner, the pull-out guide also has rails in the form of a sheet metal. Here, too, is the preferred sheet thickness, e.g. B. the components of a cabinet rail, between 0.5 mm and 1.5 mm.

The driver projection can be designed as an integral part of this base plate. For example, the driver projection can be punched out of the base plate and bent or bent over accordingly. However, it is preferably provided that the driver projection is designed in the form of a plug-on part separate from the base plate. This push-on part is preferably made of a plastic.

Overall, the base plate is essentially flat. It is preferably provided that the base plate is aligned along a plate plane. In particular, the majority of the flat surface of the base plate is aligned parallel to this plate plane.

For this purpose, it is particularly preferred that the plate plane runs parallel to the longitudinal extension of the pull-out guide and horizontally when the arrangement is in the assembled state.

According to a particularly preferred embodiment of the present invention, it is provided that the base plate, measured at right angles to the plane of the plate, has a height of a maximum of four sheet metal thicknesses, preferably a maximum of three sheet metal thicknesses.

It is preferably also provided that the base plate has a height of a maximum of two sheet metal thicknesses in the area of the first fastening device and the second fastening device. As a result, the present arrangement can be used in a piece of furniture in a very space-saving manner.

The parts of the first fastening device and the second fastening device arranged on the driver can be formed separately from the base plate. This means that these parts can, for example, be detachably connected to the base plate. However, it is preferably provided that the parts of the first fastening device and the second fastening device arranged on the driver are formed in one piece with the base plate. If these parts are designed as pins, they can be embossed accordingly in the base plate. If these parts are designed as pin receptacles, they can correspondingly be punched out of the base plate or molded into it.

For a simple embodiment, it can preferably be provided that the driver has a central plane of symmetry that is oriented at right angles to the plane of the plate. For this purpose, it is particularly preferred that, in the fastening state, the plane of symmetry is oriented at right angles to the longitudinal extension of the first pull-out guide.

The attachment state is a state in which the driver is in a position connected to the pull-out guide. This means that the driver is firmly (but detachably) connected to the pull-out guide.

In contrast, the assembly state is a state in which the entire arrangement, that is to say the pull-out guide including the driver, is mounted on the furniture body of the piece of furniture. This can also be referred to as the mounting position. This assembly state is of particular importance for the definition of the terms "horizontal" and "vertical".

According to a preferred embodiment it is provided that the part of the first fastening device arranged on the driver and the part of the second fastening device arranged on the driver are each arranged mirror-symmetrically to one another on one side of the plane of symmetry.

In principle, it is possible for a driver to have more than one driver projection. If two driver projections are provided, they should each be arranged mirror-symmetrically to one another on one side of the plane of symmetry. However, it is preferably provided that the plane of symmetry leads through the driver projection. In this case, it is particularly preferred that only one driver projection is formed on the driver.

For a further preferred embodiment it is provided that the plane of symmetry divides the driver into a first symmetry area and a second symmetry area. Thus, not only are the two parts of the first fastening device and the second fastening device arranged mirror-symmetrically to one another, but the entire driver has two symmetry areas.

It is generally possible for the driver not to be entirely mirror-symmetrical. Thus, depending on the intended use and the possible uses, asymmetrical components can be arranged on the driver. However, it is particularly preferred that the two symmetry areas of the driver are designed to be mirror-symmetrical to one another.

It is also particularly preferably provided that the pin rests against the pin receptacle in the fastening state of the arrangement. There can be a frictional connection per se. However, a positive connection between the pin and the pin receptacle is preferably provided at least in a direction of movement at right angles to the longitudinal extension of the pull-out guide.

The pin of the fastening device is inclined to the longitudinal extension of the first pull-out guide, so that a connection with the corresponding counterpart is possible. It is preferably provided that the pin protrudes vertically from the driver or from the pull-out guide in the assembled state of the arrangement.

According to a preferred embodiment it is provided that the pin has a central pin axis.

The pin axis can per se z. B. be aligned in a range of 45 ° to 135 ° relative to the plane of the plate. It is preferably provided that the pin axis is aligned at right angles to the longitudinal extension of the pull-out guide. In addition, it is preferably provided that the pin axis is aligned vertically in the assembled state.

Furthermore, it can preferably be provided that the pin has a circumferential surface which is formed around the pin axis and completely radially surrounds the pin axis. Thus, the pin is at least partially cylindrical in the geometric sense.

According to a particularly preferred exemplary embodiment, it is provided that the lateral surface deviates from the circular shape in a cross section at right angles to the pin axis. In other words, it means that the length is one from a first digit the lateral surface through the pin axis up to a first straight connecting line leading to the first point opposite the lateral surface, which is oriented at right angles to the plane of symmetry and parallel to the plate plane, is greater than the length of a second point of the lateral surface through the pin axis up to one the second straight connecting line leading to the second point opposite the lateral surface, which is aligned transversely to the plane of symmetry and parallel to the plane of the plate.

The lateral surface can in the cross-section at right angles to the pin axis z. B. rectangular or oval. It is particularly preferably provided that the lateral surface has two radially opposite flattened areas and two radially opposite convex areas in the cross section at right angles to the pin axis.

Furthermore, it can preferably be provided that the shortest straight connecting line between the flattened areas leading through the pin axis is smaller than the shortest straight connecting line between the convex areas leading through the pin axis.

It can preferably be provided that the flattened areas are aligned transversely, preferably in an angular range between 35 ° and 55 °, to the longitudinal extension of the pull-out guide. This applies when the pins are arranged on the driver. In the case of a pin arranged on the pull-out guide, the flattened areas are oriented at right angles to the longitudinal extension.

With regard to the pin receptacle of the fastening device, it is preferably provided that the pin receptacle is molded into the driver or into the pull-out guide, a recess edge of the pin receptacle being formed on the driver or on the pull-out guide.

The most important feature of the pin receptacle is that it has an insertion channel for the pin that has a constriction. In addition, it can preferably be provided that the pin receptacle has a bearing area for the pin that is separate from the insertion channel. It is particularly preferably provided that the storage area through a substantially circular recess edge, the pin receptacle is formed. This recess edge in the area of the storage area describes approximately a ¾ circle.

In order to achieve a relatively easily detachable and form-fitting attachment of the driver to a pull-out guide, it is preferably provided that the minimum clear width in the area of the narrow point of the insertion channel is smaller than the minimum clear width in the storage area. The ratio of the minimum clear width in the area of the constriction to the minimum light width in the bearing area is preferably between 1: 8 and 7: 8, preferably between 2: 5 and 4: 5.

It can preferably be provided that the minimum clear width in the region of the constriction lies transversely, preferably in an angular range between 35 ° and 55 °, to the longitudinal extension of the pull-out guide. This applies when the parts of the fastening devices on the driver are designed as pin receptacles. If the part of the (first) fastening device on the pull-out guide is designed as a pin receptacle, it is preferably provided that the minimum clear width is aligned parallel to the longitudinal extension.

For the simplest possible fastening movement, it is preferably provided that the insertion channel has a wider threading area adjoining the constriction, preferably tapering in the direction of the constriction. This threading area is preferably arranged on the side of the constriction facing away from the storage area. Thus, at the beginning of the fastening movement, the pin can be moved accordingly over the threading area in the direction of the constriction.

As such, the pin and the pin receptacle can be arranged and aligned as desired, as long as the simplest possible fastening movement is guaranteed. It is particularly preferably provided that, during an assembly movement of the pin, the narrow point of the pin receptacle can only pass if the driver is aligned obliquely to the longitudinal extension of the first pull-out guide. It is particularly preferably provided that the plane of symmetry of the driver during this assembly movement, in which the pin pass the narrow point of the pin receptacle can, at an angle between 30 ° and 60 °, preferably between 40 ° and 50 °, is aligned with the longitudinal extension of the first pull-out guide.

In and of itself it is sufficient if the attachment of the driver to the pull-out guide takes place only via the first or the second attachment device. For an even more secure hold, however, it is preferably provided that the driver has a preferably tongue-shaped clamping element which is separate from the parts of the fastening device and which is connected to the pull-out guide in the assembled state. In particular, this clamping element rests on a counter-clamping surface or on a clamping-element counterpart of the pull-out guide.

The clamping element can be arranged at any point on the driver. It is preferably provided that the plane of symmetry runs centrally through the clamping element.

For the first pull-out guide it is preferably provided that it has a body rail and a drawer rail that can be moved relative to the body rail. A middle rail can optionally also be provided for a full extension.

If a drive device is assigned to the movable furniture part, it is preferably provided that the part of the fastening device arranged on the pull-out guide is arranged on the carcass rail.

The part of the fastening device arranged on the pull-out guide (preferably on the body rail) can be designed as a separate plug-on part for the pull-out guide. However, it is preferably provided that the part of the (first) fastening device arranged on the carcass rail is designed in one piece with the carcass rail, preferably molded into the carcass rail.

Up to this point, the present invention and the arrangement have primarily been described with exactly one driver and exactly one pull-out guide. In order to have a fully functional furniture fitting for a movable furniture part in the form of a drawer, a second pull-out guide is provided, which is designed essentially as a mirror image of the first pull-out guide. In addition, a second is preferred Driver is provided for the second pull-out guide, the second driver being identical to the driver of the first pull-out guide. This enables particularly simple storage.

It is particularly preferably provided that the part of the first fastening device arranged on the second pull-out guide simultaneously forms part of the second fastening device.

According to a preferred embodiment it is provided that for the arrangement at least one drive device, preferably an ejector device, is provided for moving the movable furniture part relative to a furniture body, which drive device can be brought into operative connection with the driver.

For a safe and uniform movement of the movable furniture part, it is provided that a drive device is provided for each pull-out guide. These two drive devices are then in operative connection with the respective driver.

Protection is also sought after for a piece of furniture with a furniture body, a movable furniture part (in particular a drawer) and an arrangement according to the invention.

According to a preferred embodiment it can be provided that two drive devices, preferably attached to the underside of the movable furniture part designed as a drawer, are provided, a first drive device being assigned to the first pull-out guide and the first driver and a second drive device to the second pull-out guide and the second driver is.

Furthermore, it is preferably provided that at least in a closed position of the drawer the first drive device rests on the first driver and the second drive device rests on the second driver. In particular, the drivers on the drive devices rest against one another during an unlocking movement and a subsequent opening movement. With further opening and also with part of the Closing movement can be given a freewheel in which the drive devices are not in contact with the drivers.

If the drive device is designed as an ejector device, it is preferably provided that it has an ejector force accumulator, a movable ejector element acted upon by the ejector force accumulator and a locking device for locking the ejector element in the locking position. It is preferably provided that the ejector element can be unlocked by overpressing the drawer into an overpressing position behind a cut position of the drawer and, when the ejector element is unlocked, the drawer can be moved in the opening direction via the ejector force storage device and the ejector element.

In addition, protection is sought for a method for attaching a driver of an arrangement according to the invention to a first pull-out guide of a according to the invention. In this method it is provided that the driver is brought from a pre-fastening position in which the driver is aligned obliquely to the longitudinal extension of the first pull-out guide via the first fastening device into a mounting state with the first pull-out guide, this being done by moving the pin through the narrow point of the Insertion channel and is carried out by subsequent pivoting about the pin of the first fastening device. Thus, the pin forms a kind of pivot axis, whereby this pivoting creates a positive connection between the pin and the pin receptacle, since the relatively wide areas of the pin then rest on the recess edge of the bearing area and prevent the pin from moving through the narrow point.

In this method, it is also preferably provided that a second driver, which is identical to the (first) driver, from a pre-fastening position in which the second driver is oriented obliquely to the longitudinal extension of a second pull-out guide, via the part of the second that is arranged on the second driver Fastening device and the part of the first fastening device arranged on the second pull-out guide is brought into a fastening state with the second pull-out guide, this being done by moving the pin through the narrow point of the insertion channel and then pivoting around the pin

In Fig. 1 a piece of furniture 19 with, in this case, two movable furniture parts 2 in the form of drawers is shown in a perspective view. The two movable furniture parts 2 are mounted on the furniture body 6 so as to be linearly movable via pull-out guides 3a, 3b, which cannot be seen here. The upper movable furniture part 2 is in an open position OS, while the lower movable furniture part 2 is in a closed position SS. Each drawer has a front panel 20, a drawer rear wall 21, two drawer side walls 22 and a drawer bottom 23.

Fig. 2 shows a schematic section through a piece of furniture 19 with a furniture body 6, a movable furniture part 2, a first pull-out guide 3 a mounted on the furniture body 6 and a second pull-out guide 3 b mounted on the opposite side of the furniture body 6. The movable furniture part 2 is releasably connected to the two pull-out guides 3a and 3b. A first drive device 5a and a second drive device 5b, which together form the drive device 5 for moving the movable furniture part 2 relative to the furniture body 6, are arranged on the underside of the movable furniture part 2. If necessary, the movements of the two drive devices 5a and 5b can be synchronized with a synchronization device 24 (only shown in dashed lines). A driver 4a and 4b is connected to each pull-out guide 3a and 3b. The first pull-out guide 3a, together with the driver 4a, forms an arrangement 1. In the same way, the second pull-out guide, together with the second driver 4b, forms such an arrangement 1. The drivers 4a and 4b each have a driver projection 7. Via this driver projection 7, the respective driver 4a and 4b can be brought into operative connection with the respective drive device 5a and 5b, preferably with a catch lever of the respective drive device 5a and 5b. The driver 4a is fastened to the first extension guide 3a via the part 8a of the first fastening device 8 arranged on the driver 4a with the part 8b of the first fastening device 8 arranged on the first extension guide 3a. The second driver 4b is fastened to the second extension guide 3b via the part 12a of the second fastening device 12 arranged on the second driver 4b with the part 8b of the first fastening device 8 arranged on the second extension guide 3b. In this case, the part 8b arranged on the second pull-out guide 3b forms at the same time part of the second fastening device 12. In Fig. 2 the pull-out guides 3a and 3b on both sides are each in a fastening state B with the drivers 4a and 4b. The movable furniture part 2 is in an assembly state M with the furniture body 6.

In Fig. 3 an arrangement 1 together with a drive device 5 is shown in a perspective view. The drive device 5 has a mounting plate 25, via which the drive device 5 can be fastened to the underside of the movable furniture part 2 or to a support web of a container rail 26 which also forms the side wall of the drawer. The first pull-out slide 3 a has a drawer rail 18 and a body rail 17. In the representation according to Fig. 3 the drawer rail 18 is largely covered by the container rail 26. The body rail 18 comprises the guide part 27 (which is clearly visible in the lower area) and the, preferably angular, mounting elements 28. These mounting elements 28 are firmly connected to the guide part 27, preferably welded. The first pull-out guide 3a is attached to the furniture body 6 via the body rail 17 (preferably via its mounting elements 28) by fastening means (not shown). The longitudinal extension L of the first pull-out guide 3a is illustrated by a double arrow. The driver 4a has the driver projection 7, the part 8a of the first fastening device 8 and the part 12a of the second fastening device 12. These two parts 8a and 12a are arranged on the base plate 13 of the driver 4, preferably formed in one piece with it. In addition, the clamping element 16 is arranged on the base plate 13. The base plate 13 of the driver 4a extends essentially along a plate plane P. This plate plane P is illustrated by the area spanned by the two arrows. The plate plane P is aligned parallel to the longitudinal extension L of the first pull-out guide 3a. The plate plane P is aligned horizontally in the assembled state M. In Fig. 3 the plane of symmetry S leading centrally through the driver 4a is also illustrated by the two dashed lines and the area spanned by these lines. The plane of symmetry S is - in the fastening state B - aligned at right angles to the longitudinal extension L of the first pull-out guide 3a and at right angles to the plane P of the plate.

In Fig. 4 the arrangement 1 together with the drive device 5 is shown in an assembled state. The arrangement 1 is thus in the fastening state B.

Fig. 5 shows the arrangement 1 in a perspective view obliquely from below. It can be seen that the driver projection 7 of the driver 4a is in operative connection with the drive device 5. The part 8a of the first fastening device 8 arranged on the driver 4 is in a form-fitting connection with the part 8b of the first fastening device 8 arranged or formed on the first pull-out guide 3a. The part 12a of the second fastening device 12 arranged on the driver 4 is spaced apart from the part 8b and therefore has no function in this case (or when used on this first pull-out guide 3a).

In the Figures 6 to 9 a fastening movement of the driver 4a on the first pull-out guide 3a is shown in perspective. In this embodiment variant, the part 8a of the first fastening device 8 arranged on the driver 4a is designed as a pin 9. Likewise, the part 12a of the second fastening device 12 arranged on the driver 4a is designed as a pin 9. The part 8b of the first fastening device 8 arranged on the first pull-out guide 3a is designed as a pin receptacle 10.

In Fig. 6 the driver 4a is still in a position spaced apart from the first pull-out guide 3a. It can be seen that the pin receptacle 10 (part 8b) is formed in a mounting element 28 of the body rail 17.

In Fig. 7 the driver 4a has reached a pre-fastening position VB. For this purpose, a narrow gap is left free between the assembly element 28 shown on the left and the guide part 27 of the carcass rail 17 (see also detail from FIG Fig. 15 ), into which the base plate 13 can be inserted along the plane P of the plate. The width of the gap essentially corresponds to the thickness of the base plate 13. The driver 4a is aligned in relation to the fastening state B at an angle to the longitudinal extension L of the first pull-out guide 3a. In the detail at the bottom left it can be seen that the pin receptacle 10 has an insertion channel 11 with a constriction E. In addition, the insertion channel 11 has a broader one that tapers in the direction of the constriction E. Threading area 15. Furthermore, the pin receptacle 10 has a, preferably circular, bearing area 14. In order to reach the pre-fastening position VB, the pin 9 (with its flattened areas F1 and F2 passing the narrow point E of the pin receptacle 10) was moved essentially linearly through the insertion channel 11 into the bearing area 14. Specifically, this insertion movement takes place - with the driver 4a positioned at an angle - essentially at right angles to the longitudinal extension L of the first pull-out guide 3a.

In Fig. 8 an intermediate position ZW of the fastening movement is shown. For this purpose, the pin 9 is used, so to speak, as a pivot axis. According to the detail at the bottom left, the pin 9 has a vertically aligned pin axis Z. The driver 4a is pivoted counterclockwise about this pin axis Z, as illustrated by the arrow. The pivoting movement is guided by the circular bearing area 14 and at least one convex area F3 or F4 resting thereon. As a result, the flattened areas F1 and F2 of the lateral surface F of the pin 9 are no longer aligned with the constriction E, but rather are positioned at an angle. Thus, both convex areas F3 and F4 of the lateral surface F are at least partially in contact with the bearing area 14 of the pin receptacle 10. According to the detail at the bottom right, the clamping element 16 has not yet fully reached the clamping element counterpart 29 on the carcass rail 17. This clamping element counterpart 29 is preferably designed as a U-shaped tab in the guide part 27 of the body rail 17.

In Fig. 9 the fastening state B is reached. The driver 4a was opposite Fig. 8 further pivoted about the pin axis Z. The plane of symmetry S of the driver 4a (which divides the driver 4a into the two mirror-symmetrical symmetry areas S1 and S2) is aligned in the fastening state B at right angles to the longitudinal extension L of the first pull-out guide 3a. Due to the inclination of the flattened areas F1 and F2 of the pin 9 to the constriction E of the insertion channel 11, a form-fitting connection is provided in that the driver 4a is not released from it by a linear pulling movement on the driver 4a at right angles to the longitudinal extension L of the first pull-out guide 3a can be. In the detail at the bottom right it can be seen that the clamping element 16 makes contact with the clamping element counterpart 29. There is preferably a frictional connection between these two components.

In Fig. 10 the two pull-out guides 3a and 3b and the two drivers 4a and 4b are shown in a top view from above. The drivers 4a and 4b are in the pre-fastening position VB.

In Fig. 11 is appropriate to Fig. 10 shown a view from below.

In Fig. 12 The two pull-out guides 3a and 3b and the two drivers 4a and 4b are shown in a plan view from above, the driver 4a being in the fastening state B, while the second driver 4b is still in the pre-fastening position VB.

In Fig. 13 is appropriate to Fig. 12 shown a view from below.

Fig. 14 shows a first pull-out guide 3a together with the driver 4a in a view from below. The vertical sectional plane, which results in section AA, is drawn in and leads through the first fastening device 8.

In Fig. 15 is that to Fig. 14 corresponding section AA shown. In the detail shown on the right, the section AA in the area of the fastening device 8 is shown zoomed out. It can be seen that the pin receptacle 10 - which corresponds to part 8b - is formed in the assembly element 28 of the body rail 17. The bearing area 14 of this journal receptacle 10 is shown in particular. The storage area 14 has a minimum clear width W _{14 parallel to the plate plane P.} The pin axis Z of the pin 9 is also shown in the detail shown. The pin 9 is formed in one piece with the base plate 13 of the driver 4a. The base plate 13 in turn makes direct contact with the guide part 27 of the carcass rail 17. In addition, the shortest straight connecting line V1 in this detail is the one from the flattened area F1 of the lateral surface F of the pin 9 through the pin axis Z to the opposite flattened area F2 of the lateral surface F of the pin 9 leads, drawn. This connecting line V1 is shorter than the clear width W ₁₄ . This connecting line V1 is, however, almost as long as the clear width W ₁₁ at the narrow point E of the insertion channel 11. The pin 9 therefore fits exactly through the clear width W ₁₁ .

Fig. 16 shows a first pull-out guide 3a together with the driver 4a in a view from below. The vertical section plane, which results in section CC, is drawn in and leads - in a different direction than in Fig. 14 - through the first fastening device 8.

In Fig. 17 is that to Fig. 16 corresponding section CC shown. In the detail shown on the right, the section CC in the area of the fastening device 8 is shown zoomed out. The shortest straight connecting line V2, which leads from the convex area F3 of the lateral surface F of the pin 9 through the pin axis Z to the opposite convex area F4 of the lateral surface F of the pin 9, is shown. This connecting line V2 is approximately as long as the minimum clear width W ₁₄ in the storage area 14.

In Fig. 18 a driver 4a of a second, alternative embodiment variant is shown in perspective. In this driver 4a, only the base plate 13 is shown, the driver projection 7 is not shown. In this variant, the part 8a of the first fastening device 8 arranged or formed on the driver 4a is designed as a pin recess 10. The part 12a of the second fastening device 12 arranged or formed on the driver 4a is also designed as a pin receptacle 10. The minimum clear width W ₁₁ in the insertion channel 11 can be seen particularly well in this illustration. The two pin recesses 10 are designed mirror-symmetrically to one another in the base plate 13.

In Fig. 19 only one angular mounting element 28 of the body rail 17 is shown. The part 8b of the first fastening device 8, which is designed as a pin 9, is arranged on this mounting element 28. This pin 9 is formed in one piece with the mounting element 28. In the detail shown on the left it can be seen that the lateral surface F of this pin 9 has two flattened areas F1 and F2 and two convex areas F3 and F4. It can also be seen that the lateral surface F deviates from the circular shape in a cross section at right angles to the pin axis Z. This cross section could also - other than shown - z. B. be polygonal or oval.

Fig. 20 shows a first pull-out guide 3a together with the driver 4a in a view from below, the second variant of the fastening device 8 being shown. The vertical sectional plane, which results in the section DD, is drawn in and leads through the first fastening device 8.

On average DD the Fig. 21 and in the detail shown on the right, the pin 9 formed on the mounting element 28 can be seen as it contacts the recess edge of the pin receptacle 10 in the bearing area 14 at least in some areas in the fastening state B.
