Wall rail system

Abstract

The invention relates to a wall rail system for a shelf system or similar, comprising at least one wall rail which is embodied as a U-shaped profile, comprising a rear part which is secured to a wall, two lateral limbs which are oriented away from the wall, one rear-sided cavity which extends in the longitudinal direction on the side of the rear part which is oriented towards the wall, and at least one connecting element for connecting two wall rails which push against each other in the longitudinal direction, said connecting element being received in a connected state of the two wall rails in the rear-sided cavity. The connecting element reliably connects, fixes, and aligns the rails in relation to each other without engaging in the usable space between the lateral limbs and the rear side of the U-profile.

1 . Wall rail system comprising:
 at least one wall rail provided in the form of a U-shaped section with a rear part which can be secured to a wall and two lateral limbs extending forwards from the rear part away from the wall as well as a rear-side cavity extending in the longitudinal direction at the rear face of the rear part directed towards the wall, and   at least one connecting element for connecting two wall rails mutually abutting in the longitudinal direction, which connecting element is accommodated in the rear-side cavity when two wall rails are in a connected state.   
   
   
       2 . Wall rail system as claimed in  claim 1 , in which the wall rail has first and second orifices in the rear part in at least one lengthways end and the connecting element has first and second projections at both sides for engaging in the orifices provided in the wall rail. 
   
   
       3 . Wall rail system as claimed in  claim 2 , in which the first orifice is provided in the form of a slot disposed transversely to the longitudinal direction of the wall rail and the first projections of the connecting element are disposed at the side-ends for engaging in the first orifices of mutually abutting wall rails and cause a fixed relative positioning of the wall rails in the longitudinal direction. 
   
   
       4 . Wall rail system as claimed in  claim 2 , in which the second orifice is a rectangular cut-out at the end of the wall rail and the second projections of the connecting element are disposed centrally for engaging in the second orifices of mutually abutting wall rails and cause the wall rails to be secured to one another in the transverse direction. 
   
   
       5 . Wall rail system as claimed in  claim 1 , in which the connecting element is provided in the form of an elongate, flat metal element. 
   
   
       6 . Wall rail system as claimed in  claim 5 , in which the first and second projections are located on either side of the connecting element and extend at an angle of between 60° and 85°, preferably between 75° and 85°, with the base plane of the connecting element disposed parallel with the rear face portion of the wall rail. 
   
   
       7 . Wall rail system as claimed in  claim 2 , in which the first and second projections of the connecting element are connected to one another via a notch. 
   
   
       8 . Wall rail system as claimed in  claim 1 , in which the rear-side cavity extending in the longitudinal direction of the rear part is formed by a forwardly projecting middle portion of the rear part.
