Push device and method for installing a push device

Abstract

A pushing device for furniture or household appliances includes a first pull-out guide and a second pull-out guide, wherein each of the two pull-out guides comprises a stationary guide rail and at least one running rail which is movable relative to the guide rail and a front holder and a rear holder being fixed to each running rail, a base resting on all four holders and being secured against displacement by stops on the holders. A method for assembling a pushing device includes mounting the holders on the running rails and placing a base on each of the holders.

         7 . The pushing device according to  claim 1 , wherein a hook ( 70 ) projects from each running rail ( 7 ), to which one of the front and/or rear holders ( 9 ,  9 ′,  10 ,  10 ′) is fixed. 
     
     
         8 . The pushing device according to  claim 1 , wherein a rear end of a side wall ( 12 ) and an end portion of a rear wall ( 14 ) are fixed to each rear holder ( 10 ,  10 ′) and/or a front end of a side wall ( 12 ) and an end of a front panel ( 13 ) are fixed to each front holder ( 9 ,  9 ′). 
     
     
         9 . The pushing device according to  claim 8 , wherein the side walls ( 12 ), the rear wall ( 14 ) and/or the front panel ( 13 ) are made of a transparent plate-shaped material. 
     
     
         10 . The pushing device according to  claim 8 , wherein each side wall ( 12 ) is connected to a front panel ( 13 ) via a corner element ( 15 ) which is fitted from above. 
     
     
         11 . The pushing device according to  claim 8 , wherein each side wall ( 12 ) is connected to a rear wall ( 14 ) via a corner element ( 15 ) fitted from above. 
     
     
         12 . The pushing device according to  claim 1 , wherein a projection ( 24 ) is formed on one of the front or rear holders ( 9 ,  9 ′,  10 ,  10 ′), which projection is configured to be brought into engagement with a movable driver ( 22 ) of a self-closing device ( 20 ).
