DESCRIPTION OF THE PREFERRED EMBODIMENTS

In Fig. 1 is an embodiment of a coupling element 1 for a furniture frame for a piece of furniture, in particular for an office furniture piece such as. A work desk or the like, illustrated in accordance with the present invention. Before a detailed description first follows general explanations to the embodiments and their advantages.

The European patent described in the introduction EP 0 830 825 B1 , the contents of which are incorporated by reference into the description of this application, discloses a coupling element for a furniture frame. This coupling element has for displacing a table top arranged on it grooves, can engage in the mounted on the table top bolts. This sliding connection of groove on the coupling element and bolt on the table top is associated with a relatively large mechanical clearance. In addition, this sliding connection allows no locking of the table top in the direction of displacement.

Furthermore, the coupling element of EP 0 830 825 B1 a connector on its front side, can be coupled to the other furniture parts (in the transverse direction). The fact that such furniture parts, such as, for example, a visual protection plate or a shelf board, are mounted in the transverse direction, also increases the extension, for example. The work table in the transverse direction. In addition, it is necessary that the connector of the coupling element is accessible to be able to infect the furniture parts, which, for example, requires the departure of the work table from a wall.

The inventors have now recognized that by providing a planar guide section on a coupling element for the assembly of a furniture frame, the displacement properties for a plate displacement, in particular transverse direction, can be improved. In addition, by providing at least one attachment point, a functional rail can, for example, be coupled from above to the coupling element.

Consequently, embodiments of a coupling element for the assembly of a furniture frame, in particular a work table frame, with at least one longitudinally extending longitudinal member for connection of the coupling element at least one attachment point for the side member, at least two transversely offset connection points for each furniture support and at least one flat and transversely extending guide portion for receiving a plate displacement member. The coupling element is longer than wide in some embodiments. In the following, the transverse direction is understood to be the direction of the coupling element which lies along the longer extent of the coupling element.

The guide section extends, for example, at an edge of the coupling element, which points in the direction of the coupled longitudinal member. The guide portion is formed continuously in some embodiments, while in others, for example, is divided by the attachment points for the side member in two sections. In some embodiments, a single plate displacement member is provided for each guide portion.

The guide section is substantially flat, for example web-like on an edge of the coupling element, so that the plate displacement member, which is attached, for example, to a cover plate, for example a tabletop, can slide along the surface section. The guide portion is formed thinner in some embodiments in its vertical extension than other areas of the coupling element.

The connection points of the coupling element for the furniture supports are, for example, designed as through holes and can, for example, accommodate different furniture supports, such as. C-foot, T-foot or 4-foot furniture supports. The furniture supports can be releasably connected to the coupling element in some embodiments, while being bolted to others, for example.

For this purpose, the coupling element in some embodiments has a number of transversely offset attachment points for various types of furniture supports. On an underside of the coupling element further recesses or elevations may be provided adjacent to recess locations to provide an anti-rotation device for a furniture support, so that the furniture support can be attached to the coupling element in only one specific position.

In some embodiments, the coupling element further comprises roller mounts. The roller mounts are adapted to receive corresponding rollers, which serve as a rolling bearing for the displacement of a table top. The roller receivers are, for example, designed as recesses arranged offset to one another in the transverse and / or longitudinal direction in the coupling element. The staggered arrangement ensures a uniform weight distribution of the tabletop on the individual recorded roles. The roller receptacle can furthermore have a shape which does not have a circular cross section, that is to say, for example, is triangular, rectangular, oval, or polygonal, in order to prevent a rotation of the roller arranged in the roller receptacle.

In some embodiments, the coupling element has at least one connection for a functional rail. This connection for the functional rail is, for example, a through-bore, which in some embodiments is arranged on an edge region of the two front sides, that is to say the sides on the transverse direction of the coupling element.

In some embodiments, at least one connection point for the furniture support is simultaneously formed as a connection for the functional rail and / or as connection points for a relay element, a receptacle for a printer holder, a PC holder and / or for a chaining element.

In some embodiments, the coupling element further comprises at least one connection for a cable guide and / or a connection for a block position for a plurality of table racks, a legroom panel and plate recess. In addition, in some embodiments, screw holes are also provided for a plate screw connection on the upper side of the coupling element.

In some embodiments, the coupling element is formed symmetrically, so that the coupling element for a left side as a cross member, for example. A table and can be used for the right side of a table. In this case, for example, the connections and / or the attachment points and the guide portions are symmetrical to a central mirror axis extending in the middle of the coupling element along the narrow direction, i. perpendicular to the transverse direction, extends, formed.

In some embodiments of a furniture frame, in particular a furniture frame for a work table, the furniture frame has at least one longitudinal carrier and at least two coupling elements as described above. The longitudinal member is coupled in each case to the attachment points of the two coupling elements, so that the longitudinal member and the two coupling elements a double-T-like support structure, for example. Cover plate as a table top results. The coupling elements are arranged as a cross member. At least one furniture support is coupled to the coupling elements. For the plate displacement, in particular in the transverse direction, at least on each guide section at least one plate displacement member is further coupled and on the side member a Plattenarretierungselement.

The plate displacement element serves, for example, as a kind of slider on the guide rail of the coupling element.

The Plattenarretierungselement is configured to lock a coupled to him table top in the direction of displacement.

The plate displacement member, which is coupled to the respective guide portion of the respective coupling element, engages in the respective guide portion one that it can slide along it on the one hand, and on the other hand prevents, for example, a table top connected to it can be raised. For this purpose, it has in some embodiments, a groove-like portion in which the guide rail can slide along. In some embodiments, the plate displacement member is configured to assume two states, a working state or a locked state in which it can slide along the guide portion and prevent a tabletop disposed thereon from being lifted and a second state (unlocked state) it no longer or only partially engages in the guide portion and thus allows a tool-free removal of a table top of the furniture frame.

In some embodiments, the plate displacement member has a guide tab which, for example, engages on an underside of the guide portion of the coupling element when, for example, the plate displacement member is in the working state. In the second state, for example, the guide tab is positioned away from the guide portion such that the disc displacing member is no longer engaged with the guide portion and thus the disc displacing member can be removed from the guide portion.

In some embodiments, a roller element is further, for example. Slidably coupled to the side rail, which serves as a bearing for a displacement and support of the table top or the like.

In some embodiments, the longitudinal member has one or two longitudinally extending guide portions, on each of which one or more roller elements or one or more plate locks can be slidably arranged. For this purpose, the roller element or the plate lock are designed such that they can engage in the respective guide portion of the longitudinal member.

Further, in some embodiments, the plate lock disposed on the side rail has a support portion that supports the table top. In addition, further support elements may be arranged on the longitudinal member, which are formed, for example, in at least one of the guide rails to engage the longitudinal member.

In some embodiments, the furniture frame further comprises a functional rail, which is, for example, as mentioned above, coupled via the corresponding connection to the coupling element with the coupling element. The functional rail has, for example, a first carrier section and a second carrier section spaced therefrom, so that a groove-like depression is formed between the two carrier sections. The distance between the two support sections, i. the width of the groove-like depression is variable in some embodiments. As a result, the functional rail is flexible and it can be coupled to her various other furniture elements, such as, an organizational wall or the like. Furthermore, in some embodiments, the functional rail has a groove in the first and / or second support section, which is formed on an underside of the functional rail. At this groove, which extends along the support portion, more furniture elements can be coupled.

In some embodiments, the functional rail can be coupled to the coupling element via a connecting element. The connecting element is designed so that it can engage on the one hand in the functional rail and on the other hand with the corresponding connection to the coupling element is connectable (eg. There can be inserted by means of a plug connection or screwed or the like).

In some embodiments, a cover, for example. A cable cover is further provided on the furniture frame. The cover is pivotally coupled by means of at least one pivoting element on the furniture frame, for example. On the function rail. In some embodiments, the pivoting element is designed such that it can hold the cable cover in at least two positions, in a first in which the cover is flush with a tabletop, for example, and in a second in which the underside of the cover is accessible. In some embodiments, the pivoting element also has an electrical connection, for example a socket, which is accessible in particular in the second position of the cover.

In some embodiments, a kit for the assembly of a stand for a piece of furniture, in particular for a work table as building blocks at least one coupling element, as described above and at least one furniture support, wherein the at least one furniture support on the coupling element over there provided Attachment points is releasably connectable. In some embodiments, the kit has as further components, for example, the functional rail, as described above, or further of the elements described above.

In some embodiments, a kit for the assembly of a piece of furniture, in particular a work table whose frame has at least one longitudinal beam and at least two cross members, on each of which at least one furniture support is arranged, at least two coupling elements as cross member blocks, as described above. Furthermore, the kit has as a building block at least one longitudinal member which is connected via the respective connection point with the coupling elements and also has at least two furniture supports, which, as stated, are attachable to the coupling element.

In addition, in some embodiments, the kit further comprises a plate, in particular a table top and the plate displacement member, wherein the plate is connected to the plate displacement member. Furthermore, the kit can still, for example. Rolls or roller element, which are arranged, for example, on the coupling element and / or on the longitudinal member and, for example. Have the disk lock described above. In addition, the kit may still have the functional rail described above. In some embodiments, the kit further comprises the cover described above with the pivoting element (and, for example, the power connector), which, for example, is pivotally coupled to the functional rail. In some embodiments, the kit further includes the above-described carrier, which are arranged on the side rail to support the table top. In some embodiments, the kit further includes other furniture parts or other parts, as described above, such as. A linking element, PC mount, Beinraumblende, plate recess, organization wall or the like.

In the embodiments, said components can be coupled to the coupling element or to the functional rail. The coupling is realized, for example, as a (inset) plug-in connection or as a screw connection or another type of mechanical connection known to the person skilled in the art.

Coming back to the Fig. 1 to 10 Are there the various embodiments of a coupling element 1 ( Fig. 1 and 2 ), a plate lock 13 ( Fig. 3 to 6 ), one Plate displacement member 27 ( Fig. 7 and 8th ), a functional rail 30 ( Fig. 9 ) and a cable cover 40 ( Fig. 10 ).

The coupling element 1, which is designed as an injection molded part, has various connections or connection points 2 to 10 and 45, which are arranged symmetrically to a mirror axis which runs centrally along the narrower extension of the coupling element 1. The coupling element is elongate, so that its longitudinal extent is greater than a width dimension. As mentioned above, the longitudinal extent of the coupling element 1 corresponds to a transverse direction, since the coupling element 1 is typically arranged with the transversal expansion as a cross member on a furniture frame for a rectangular worktable. However, the coupling element 1 is not limited to this arrangement and shape and can basically be formed in a variety of forms and for a variety of arrangements and furniture racks.

On a front side of a longitudinal side of the coupling element are three connection points 2 for the connection of a longitudinal member 16 (s. Fig. 3 to 6 ), which are formed as through holes. In the connection points 2, the longitudinal member 16 can be coupled by means of a plug connection to the coupling element 1 or, in other embodiments, for example, be screwed. In this case, the attachment sites 2 may, for example, also be formed as screw holes.

Furthermore, the coupling element 1 has transversely offset leg attachment points 5, 9, 10 and 11 for furniture supports, which are formed as through-holes. In each case, a Beinanbindungsstelle 5, which is arranged in each case at one end of the longitudinal extent of the coupling element 1, provided as a connection point 5 for a 4-foot furniture support or simultaneously as a connection point 5 for a function rail 30. Further, each three attachment points 9 are provided as offset positions for the 4-foot furniture support. Another two connection points 10 are provided as leg connection for a T-foot furniture support and again another two attachment points 11 for a C-foot furniture support. The Beinanbindungsstellen 5, 9 10 and 11 are of similar design, whereby they can also, as explained in the leg and functional rail connection 5, various parts for a furniture frame. The Beinanbindungsstellen 9, 10 and 11 can also be used together as a connection for a linear connection to further coupling element of another table. In addition, they serve as a recording, for example, a Printer tray, a PC mount or a Verkettungswinkels with multiple coupling elements can be linked together.

To ensure the rotation, for example. When connecting an asymmetric 4-leg column, the coupling element 1 has on its underside. Wells 12 on. These ensure a rotationally fixed connection of such a 4-foot column by engaging corresponding projections on the 4-foot column in the recesses 12 during coupling.

Further, the coupling element 1 screw holes 7, to which a cover plate, such as a table top or the like, can be screwed.

In addition, the coupling element 1 on two guide webs 3, 4, which - seen in the transverse direction - extend before and after the connection 2 for the longitudinal member 16 in the transverse direction. The guide webs 3, 4 are formed flat and their thickness is thinner than the average total thickness of the coupling element 1. The guide webs 3, 4 are formed as a recess on the longitudinal side of the coupling element 1, which points in the direction of the longitudinal member 16. Thereby, the plate displacement member 27 (FIG. Fig. 7 and 8th ) Also accessible if, for example, the work table, in which the coupling element 1 is used for the work table frame, with the outer Koppelementseite, ie the guide webs 3, 4 opposite, is on a wall. The fact that the guide webs 3, 4 are formed as a depression, which serve - seen in the transverse direction - front and rear elevations serve as a limitation for a displacement region of the plate displacement member 27th

For the displacement of the table top in the transverse direction, the coupling element also still has three roller seats 6 on each longitudinal side. The roller mounts 6 are offset in the transverse and width direction of the coupling element 1 in order to allow a uniform weight distribution on the roles taken in them (not shown). The roller receivers 6 are formed as depressions on the upper side of the coupling element 1 and have a rectangular cross-section. Corresponding rollers can, for example, be clipped into the roller receptacles 6 and, due to the rectangular cross-section, seated in the roller receptacles 6. The rollers have, for example, a roller retainer adapted to the roller receptacle 6, on which two tabs are formed which engage in corresponding recesses in the roller holder 6 can engage.

The coupling element 1 also has near the side facing the longitudinal member three connection points 8 for the coupling of a cable tray (not shown).

In addition, the coupling element 1 still has two attachment points 45, which serve as a connection, for example, to a leg space diaphragm 36 (as in FIG Fig. 10 shown) or serve a plate recess or are provided for a block position with multiple tables.

Two coupling elements 1 can be connected to one another via a longitudinal member 16, such as, for example Fig. 3 is apparent. The two cross members serving as coupling elements 1 together with the side member 16 form a double-T-like support structure.

On the longitudinal member 16 two further support elements 15 are arranged on the left and right of the plate lock 13. In this case, the coupling elements 1 form with the rollers 6 received in the roles, the Plattenverschiebungsglieder 27, which are arranged on the guide webs 3,4, the support members 15, the plate lock 13 and one (or more) roller 14, which also on the longitudinal beam sixteenth is arranged, a total of a receptacle for a table top (not shown), which allows easy displacement of the table top in the transverse direction.

The support members 15 extend on both sides of the longitudinal member 16 and serve on the one hand as a support for the table top and on the other hand they form a sliding surface and the table top can also slide along. In addition, it may be provided in some embodiments that the carriers also have a locking device that locks the displacement of the table top.

The plate lock 13 has a support arm 26 (FIG. Fig. 6 ), which extends on one side of the longitudinal member 16 in the transverse direction and which can additionally support the table top. In addition, the plate lock on a locking element 18 which is screwed by means of screws 25 to the table top.

The locking element 18 has an opening 21 into which a corresponding projection 22 of a handle 17 of the plate lock 13 can engage. The handle 17 is rotatably mounted on an axle 23 which is connected to a clamp 24 of the plate lock 13. When the handle 17 is moved downwards, ie away from the table top, the projection 22 releases the latching element 18. If the handle 17 in the direction of When the table top is moved about the axis 23, the projection 22 engages in the opening 21 of the latching element 18 and thus blocks a displacement of the table top in the transverse direction. On the axis 23, a tension spring (not shown) is arranged, so that the handle 17 in the locking position in which the projection 22 is in engagement with the opening 21 is held, and thus locks the table top.

The clamp 24 is designed so that it engages in a guide rail 17 of the longitudinal member 16 and can be moved along the guide rail 17 along. The clamp 24 is locked, for example, by means of a screw which is screwed from below into the clamp 24 on the guide rail 17.

In order to facilitate the displacement up to the locking of the table top on the furniture frame formed from coupling elements 1 and longitudinal member 16, the locking element 18 has a beveled portion 52, so that the table top with the locking element 18 can be easily pushed along the support arm 26 of the plate lock 13, since the chamfered area 52 serves as a kind of ramp for the table top upon displacement.

In addition, the latching element 18 has a stop area 53 (FIG. Fig. 5 ), which prevents the engagement of the projection 22 in the opening 21 when moving the table top and thus serves as a pinch protection. The stop region 53 is formed as a slot in the latching element 18, in which the projection 22 engages during the displacement of the latching element 18. When the projection 22 reaches the end of the slot 53, the locking element 18 can not be moved further. In order to engage the projection 22 in the opening 21, the handle 17 must be actuated, ie pressed down to pull the projection 22 from the stop area 53. Only then can the displacement of the table top continue and the projection 22 engage in the opening 21 and lock the table top.

In order to further facilitate the displacement of the table top, a roller 14 (on the side member 16) (FIG. Fig. 4 ) on which the table top can slide along. The roller 14 has a clamp 54, which is clamped to a further guide rail 19 of the longitudinal member 16. The clamp 54 is designed so that it is displaceable along the guide rail 19 of the longitudinal member.

Thus, both the roller 14 and the disc lock 13 in any Position along the longitudinal member 16 are brought. It is also possible to provide both the plate support serving as a roller 14 and the plate lock 13 (and the support members 15) multiple if necessary on the side rail 16.

As a further element of the plate displacement of the table top is the plate displacement member 27 which is provided in each case on a guide web 3 and 4 of the coupling element 1 ( Fig. 3 . 7 and 8th ). At the in Fig. 3 Illustrated furniture frame are therefore a total of four, on each coupling element 1 two, plate displacement members 27 are provided.

The plate displacement member 27, which is fastened to the table top by means of screws, serves on the one hand the displacement along the respective guide web 3, 4 on the coupling element 1 and on the other hand as a locking of the table top, so that it can not be lifted. For this purpose, the plate displacement member 27 has a flat area on a housing 55 of the Plattenverschiebungsglieds 27, which rests against the table top, and extends beyond the housing and thus rests on the upper side of the guide web. The plate displacement member 27 further includes a guide plate 29 which rests on the underside of the guide web 3, 4 of the coupling element 1. As a result, the upper region with the guide lug 29 forms a groove-like depression on the side of the housing 55 which points in the direction of the guide rail 3 or 4, in which the guide web 3, 4 can slide along. The distance of the guide tab 29 and the upper portion of the housing 55 is dimensioned such that the guide web 3, 4 can slide with little play in the groove formed.

The plate displacement member 27 further has a handle 28 for actuating the plate displacement member 27. The handle 28 is connected to the guide tab 29 inside the housing 55. When the disc displacement member 27 is in a working state (lock state) (see FIG. Fig. 7 ), ie the handle 28 is pushed into the housing 55, the guide tab 29 is disposed outside of the housing 55 and the groove described, in which the guide web 3, 4 slides along, is formed. Now, when the handle 28 is pulled out (s. Fig. 8 ), the guide tab 29 enters the interior of the housing 55 and thus releases the guide web 3, 4, so that the table top can be lifted. Thus, the plate displacement member 27 allows a tool-free assembly and disassembly of the tabletop or any other Object attached to it.

The handle 28 further includes a projection 51 which can engage an aperture 50 of the housing 55 when the handle is in the extended position, i. in the unlocked state, and thereby the guide tab 29 is pulled into the housing. As a result, the handle engages with the projection 51 in the openings 50 of the housing and is locked. Another detent point is formed inside the housing 55, which locks the handle 28 in the working position with the guide tab 29 extended. Further, located inside the housing 55 is a compression spring that pushes the guide tab 29 outward, so that the plate displacement member 27 can not be accidentally unlocked.

Furthermore, the coupling element 1 has on its underside two obliquely extending on the guide webs 3, 4 boundaries 67, 68 (s. Fig. 2 ), which are arranged in a central region of the coupling element 1. The boundaries 67, 68 are formed as two web-like projections which each extend obliquely from the inside to the outside on the respective planar guide web 3, 4 such that the guide tab 29 is pressed when moving to within the housing 55, when they reach the corresponding boundary 67, 68 abuts. As a result, the limits 67, 68 also form a limit to the displacement of the plate displacement member 27, since the guide plate 29 must be moved against the spring pressure, and thus a certain limitation for the displacement of the attached table top. This also facilitates, for example, the tool-free removal (or placement) of the table top with the plate displacement members 27 on the furniture frame, as for example. In a stop position, the guide tab 29 pressed by the boundary 67 or 68 in the housing 55 and thus the guide plate 29 the guide bar 3 or 4 releases. Thus, for example, a user who wants to remove a table top and has moved this in the transverse direction to an end position, unlock the respective Plattenverschiebungsglieder 27 only on one side, if he wants to remove the table top, as on the opposite side of the boundary 67 or 68, the guide plate 29 has already pressed and the corresponding plate displacement member 27 has released.

An embodiment of the functional rail 30 with a connecting element 34 for connection to the coupling element 1 is shown in FIG Fig. 9 illustrated. The functional rail 30 has two carrier rails 31 and 32 which are spaced from each other are. The carrier rails 31 and 32 are substantially flat except for a longitudinal groove 57 or 58 and serve to receive other furniture parts, such as. An organization wall 36 (FIG. Fig. 10 ).

The carrier rails 31 and 32 are further arranged on a function carrier 56, which is designed to change the distance between the carrier rails 31 and 32. The carrier rail 32 is fastened to a profile section 33 of the function carrier 56, which is screwed by means of screws 44, which engage in a screw block 61, with a second profiled section 62 of the function carrier 56. The screw block 61 is arranged in a cavity 63 of the second profile section 62. If the screws 44 are tightened, they pull the first profile section 33 in the direction of the second profile section 62. Since the carrier rail 32 is connected to the first profile section 33, the carrier rail 32 is also displaced in the direction of the other carrier rail 31 when the screws 44 are tightened so that the distance between the two carrier rails 31, 32 becomes smaller. Conversely, the distance between the support rails 31, 32 increases when the screws 44 are released.

The functional rail 30 is connected to the connecting element 34 with the coupling element 1. For this purpose, the connecting element 34 has a through bore 35 through which the connecting element 34 can be screwed to the connection point 5 of the coupling element 1. Furthermore, the connecting element 34 has an extended portion 64, which engages in a cavity 59 which is formed between the profile section 33 and the second profile section 62. The extended portion 64 of the connecting element 34 is not centered, but based on Fig. 9 , arranged right from the center. When the screw 44 is tightened, the extended portion 64 clamped in the cavity 59 and thereby connects the functional rail 30 with the coupling element first

To the or the connection elements, which is or are connected to the functional rail 30 with the support rails 31, 32, as the organization wall 36 (FIG. Fig. 10 ), a clamping profile 38 can also be clamped in the cavity 59 for securing. The clamping profile 38 engages in two undercuts 65, 66 (FIG. Fig. 9 ) formed on the first profile portion 33 and the second profile portion 62 in the cavity 59. As a result, the clamping profile 38 prevents the profile section 33 from tilting relative to the profile section 62 and thus reliably preventing it from coming off Organizing wall 37 which engages in the grooves 57, 58 of the support rails 31, 32 and the intermediate space therebetween.

Furthermore, the second profile section 62 has a longitudinal clamping rail 60 at its lower end, coupled to the other furniture and / or frame parts, for example. Clamped, can be.

As in Fig. 10 is shown, in each case a first cable flap 39 and a second cable flap 40 via a respective flap mechanism 41 is clamped to the clamping rail 60. The first cable flap 39 is shown in a 60 ° position, whereby the space lying under the cable flap 39 is accessible, so that an outlet arranged below it (not shown), which is integrated, for example, in the flap mechanism 41, is easily accessible. The flap mechanism 41 is not only designed to hold the cable flap 39 in the 60 ° position, but, for example, to lock in a 90 ° position, as is the case with the second cable flap 40. In addition, the flap mechanism 41 in some embodiments, a third position, so that the cable flap 39, 40 engages in a 180 ° position. In the position of the cable flap 40, the surface of the cable flap 40 is substantially flush with the table surface (not shown). Furthermore, the flap mechanism 41 is adapted to fold away the cable flaps 39 and 40 completely downwards. To actuate the flap mechanism 41, this has a release lever 42 which releases the flap mechanism when actuated. In order to prevent an unrestrained fall of the cable flap 39, 40 upon actuation of the release lever 42, the flap mechanism further comprises a mechanical damping, which brakes the pivoting of the flap mechanism 41. The flap mechanism 41 also has a double web 49, which is both rotatably mounted on the holder 46 and on the clamping foot 43, whereby the flap mechanism 41 in the various positions (60 °, 90 ° or 0 °) can be brought.

The flap mechanism 41 is screwed via a holder 46 with the respective cable flap 39, 40. In addition, the flap mechanism 41 has a clamping foot 43, which is suitable for correspondingly engaging in the clamping rail 62, so that the cable flap 39, 40 can simply be clamped or clamped with the flap mechanism 41 on the clamping rail 62.
