Description

The present invention relates to a plug connection with a frame casing and a Zargenadapter, wherein the Zargenhülle in particular having a U-shaped or approximately U-shaped cross-section, with at least one connected to a wall of the frame shell with this by at least one connector Zargenadapter, wherein the connector in the Substantially consists of a provided on the wall pocket and an insertable into this pocket and running transversely to the longitudinal extent of the frame cover tongue and the tongue is in the region of a recess of the frame adapter, wherein the recess with a first stop and a first locking lug transversely to the direction of insertion of the tongue runs.

A frame cover of the generic type is from the WO 2011/048003 A1 known.

The present invention has for its object to further simplify a connector between a frame shell and a frame adapter of the generic type with respect to the connection of at least one Zargenadapters and improve.

This object is achieved by a connector with the features of claim 1. In this case, the stop and the locking lug are so on a boundary web of the bag, that the boundary web between the stop and the locking lug is positioned and held in such a way that the tongue is secured against pulling out of the bag.

By such a construction several advantages are achieved.

On the one hand, such a designed connection between frame casing and frame adapter is secured against rotation, so that in particular in - seen in the longitudinal direction of the frame cover - short Zargenadaptern a connector may be sufficient, resulting in a simplified production.

On the other hand, with a symmetrical configuration of the plug-in connection, it is possible to use the same tools for producing the cut-outs as well as the pockets, both for left and right versions of frame sleeves, so that a complete set of tools is saved.

Further features of the invention are the subject of dependent claims.

In the drawings, the reference numeral 5 is a frame shell and designated by the reference numeral 6, a Zargenadapter, with the frame cover 5 by at least one connector 7 (see, in particular FIG. 5 ) connected is.

The plug connections 7 are essentially formed from pockets 8 formed on a side limb 5a of a frame shell 5 and from tongues 9 on the frame adapter 6, wherein the tongues 9 can be inserted into the pockets 8 in a direction extending transversely to the longitudinal extent of the frame shell 5.

The tongues 9 in the Zargenadapter 6 are each in the region of a recess 10, which is preferably formed by a punched.

The pockets 8 in the side legs 5a of the frame cover 5 are in the region of a folded material strip 5b and are issued from this folded material strip 5b out. The pockets 8 are pronounced so far that the side leg 5a creates a free space in the material thickness of the tongues 9. By the tongues 9, which engage in the pockets 8, thus a determination of the frame adapter 6 relative to the side legs 5a of the frame cover 5 is achieved perpendicular to the plane of the side leg 5a. The tongues 9 are provided in their front areas with a bend 9a, which corresponds approximately to the material thickness of the material strip 5b. Thus, with retracted tongue 9, the free end 9b of the tongue 9 on the inside of the side leg 5a of the frame cover 5 and thus prevents a possible movement of the frame adapter 6 in the direction of the side leg 5a.

As can be clearly seen from the drawings, the pockets 8 as well as the recesses 10 are mirror-symmetrical to the respective tongues 9.

Accordingly, the recess 10 is provided with centrally adjacent to the tongue 9 and transversely to the insertion direction of the tongue 9 extending stops 10a, which rest after the complete insertion of the tongues 9 in the pockets 8 abutment surfaces 8d of a first boundary web 8a and a boundary web 8b. Both boundary webs 8a and 8b extend obliquely with respect to the direction of insertion of the tongue 9 such that the spacing of the two boundary webs 8a and 8b widens toward one another toward the top of the side wall 5.

The stop surfaces 8d are in the region of notches 8c of the material stiffener 5b.

As in particular from the FIG. 3 As can be seen, the frame adapter 6 is provided in the region of its recess 10 with securing lugs 10b arranged symmetrically to the tongue 9. These safety lugs 10b are in the retracted state of the tongue 9, the upper-side ends 8c of the limiting webs 8a and 8b engaging behind on. This is in the assembled state pulling the tongue 9 out of the pocket 8 is no longer possible.

The restricting webs 8a and 8b ensure that the securing lugs 10b are lifted slightly out of their original plane parallel to the transferred material strip 5b during assembly of a frame adapter 6 until the securing lugs 10b are moved out of the guide region of the limiting webs 8a and 8b. In this situation, the locking lugs 10b move through the resilient restoring forces of the material in the direction of the side leg 5a of the frame cover 5 and engage behind the respective pockets 8, so now the tongues 9 of the frame adapter 6 and thus of course the entire frame adapter 6a against unintentional release of the Frame cover 5 is secured.

Due to the symmetrical design of the connectors 7 now more forces are removed due to the loading of a drawer over two locking edges.

The connectors 7 are secured due to the symmetrical construction against rotation about a perpendicular to the side legs 5a axis.

This results in a torsionally rigid overall design, in addition it is also possible to define a frame adapter 6 with only one connector 7 on a frame shell.

Dynamic loads can also be better absorbed, especially regardless of whether a right- or left-handed torque is applied by dynamic loads.

A practical advantage not insignificant advantage is the fact that no tool set with left and right tools must be kept ready by the symmetrical design of the connector 7.

In order to facilitate the transfer of the securing lugs 10b into the fixing position, that is, into the position which overlaps the limiting webs, the embossing radii of the limiting webs 8a, 8b of the pocket 8 formed from the material strip 5a are tapered toward the top side.

The FIGS. 8 and 9 show schematic representations of pockets 8 and 8 '. In the pocket 8 are each a stop 10a and a safety nose 10b mirror-symmetrically they are the stop 10a 'and the locking lug 10b' opposite. The FIG. 9 has in the pocket 8 'on no mirror-symmetrical arrangement of stops and locking lugs.
