The invention relates to a in a horizontal cross-section C-shaped post means Screw and clamping plate clampable locking element, on which a shelf support rests, with the free C-legs of the. Post around a are bent outwards at right angles and the shelf support within the post is Z-shaped like this is bevelled so that it rests against the inner surface of the C-leg and the lateral Pföstenfiäne.

It is known to fasten a shelf support in a horizontal cross-section, for example C-shaped post. The end of the shelf support that engages inside the post is the contour adapted to a cross-sectional area. The shelf support fills with its bent inner End about half the cross-section of the post. This end has a certain vertical extension, so that when the shelf support is loaded, a wedge effect occurs, due to which the lower Rear edge of the inner end of the shelf support pressed against the rear wall of the post and the upper front edge or the upper front portion of the bent inner end of the shelf support is pulled forward against the free C-leg of the post. By means of a clamping piece, that is inserted from the front into the cross-section not filled in by the rear end of the shelf support is, the shelf support can be relative to a lateral displacement or rotation secure to the post. The support arm approach, d. H. the inner end of the support arm is rolled up in a tubular shape and not Z-shaped. The stability of the known attachment is particularly at the upper edges unsatisfactory. Furthermore, after a certain operating time, the cooperating with the clamping piece Legs of the post are gradually bent so that the inner cross-section of the Post is slightly enlarged, which is sufficient to create such a large play for the clamping piece, that this can no longer be held in the post by itself, but at least in the event of vibrations slides out, with which the secure attachment is no longer guaranteed, but on the contrary there is a risk that the shelf support will detach itself from the post and as a result of the him resting load falls out of the post. In addition, the known fastening is in the process of being manufactured cumbersome and time-consuming.

It is also known a fastening for a support frame, in which the posts are provided with closing holes Holed skid. Bolts attached to support arms can be inserted into these holes.

Ie depending on the load and the length of the support arms arise in the edge zone of the holes of the Post embedment chipping. These areas are damaged after a certain period of operation, d. That is, the material tears out, so that a secure attachment is no longer possible. The bolts too in the support arms can loosen after prolonged operation, so that there is also an uncertainty factor here. In addition, with such a Fastening no stepless height adjustment of the support arms possible. Finally, the manufacturing cost of such fastenings is great. In contrast the attachment of the support arms according to the invention is statically flawless, since that at the clamping point the moment occurring in the support arms and the transverse force taken from the support arm attachment alone while the Feststellgüed only serves to secure the position of the support arm.

Finally, an attachment for support arms in posts is also known, in which a vertical projection pulled into a corresponding vertical slot of the post on the support arm attachment and by means of a fastening plate engaging behind the rear boundary walls of the slot in the post and one that can be screwed into it from the outside

to be operated screw is clamped. In this version, however, the wedge effect of the support arm approach occurs does not appear in the post, d. i.e., the fastening

To prevent the carrier 26 relative According to the invention, this task is shifted laterally to the post 24. that the locking member is provided with an upward link 54, which is roughly hat-shaped with side pieces the folds of the post extending i ° walls 56 and outer flanges 58 is formed, Has fingers on both sides of the folds being removed from the yoke of the hat-shaped locking member an elongated finger 60 extends upward one of the shelf support thickness corresponding to 54, the has stood. on both sides of the bevelled post front wall The invention has the considerable advantage is ER- portions 48 a of the strength of the shelf support is sufficient that both the-support arm is set and the corresponding distance ^l 5 26. The locking member locking member can be manufactured cheaper. The 54 is by means of a screw 64 and a counter-locking member is an independent of the bracket plate 62, which from behind against the front walls 42 organ. The inventive design of the fixed post 24 is pulled at any height of the actuator enables both a shelf post 24 to be fixed. The approach 36 of the shelf support as well as two shelf ^{supports within an ao} carrier 26 is thus to be secured against lateral displacement of the post without being secured on the locking member.
Changes need to be made. As can be seen in dashed lines from FIG. 3 results in On the basis of the drawing, an execution post 24 next to the shelf support 26 a represents example, the invention is explained in more detail. mirror-inverted shelf supports It shows 25 being placed without the locking member 54 being changed. Fi g. 1 is a perspective view of a fastener needs to be attached, wall for shelf boards, in Figs. 6 to 9 various deviated Fig. 2 is an enlarged perspective view of the cross-sections of the post 24 shown.

Of the 6 to 9 different post cross-sections. Post 70 according to the embodiment according to FIG. The fastening wall 20 according to FIG. 1 again comprises a rear wall 76, two side walls from individual fastening walls 22, posts 24, 80, two front walls 78 and two inwards Shelf supports 26 and shelf 28. The latter 4 ° canted sections 74 with inner support surfaces 72. have longitudinal lines on their underside. This post has a smoother outer contour.
