Device for accomodating trolley, method for manufacturing a trolley as transport means

Abstract

A trolley for accommodating objects includes a housing. The housing includes a bottom wall; two upright side walls and a top wall arranged substantially parallel to the bottom wall and transversely between the side walls. Each side wall extends from the bottom wall, and at least one side wall includes a panel with a core covered on either side with an inner layer and an outer layer, respectively, and at least one outer edge with a plastic rim forming a shock-absorbing edge. The plastic rim is molded onto said outer edge such that the plastic rim surrounds the outer edge of the panel.

         10 . The trolley of  claim 10 , wherein the plastic extends from the cutout through the core, from the inner layer to the outer layer of the panel. 
     
     
         11 . The trolley of  claim 1 , wherein a series of spaces is arranged on the inside of each side wall, wherein the series of spaces run parallel to and at a distance from the top edge of said side wall, wherein the top wall is provided on its longitudinal edges with a series of lips, and wherein the lips on the top wall are received in these spaces in the side walls. 
     
     
         12 . The trolley of  claim 1 , wherein an upright partition is fitted transversely between the side walls, wherein the partition is provided with lips at least along its longitudinal edges, wherein an upright series of spaces is provided on the inside of each side wall, wherein the series of spaces extends from the bottom wall to the top wall, and wherein the lips of the partition are received in said spaces in the side walls. 
     
     
         13 . The trolley of  claim 1 , and further comprising at least one door pivotably connected to an upright side wall, wherein the at least one door comprises a core covered on either side with an inner and an outer layer, respectively, a plastic rim on a peripheral edge of the door, and guides for supporting serving trays on the inside facing interior of the housing. 
     
     
         14 . The trolley of  claim 13 , wherein the door comprises two door panels, and wherein each door panel comprises a core covered on either side with an inner layer and an outer layer, respectively, and a plastic rim on its peripheral edge. 
     
     
         15 . The trolley of  claim 14 , wherein each door panel is provided with a plastic handle integrally molded with the plastic rim. 
     
     
         16 . The trolley of  claim 13 , wherein the guides each comprise a series of pins inserted in holes in the door panel. 
     
     
         17 . The trolley of  claim 1 , wherein each inside of the side walls facing an interior of the housing is provided with guides for supporting serving trays. 
     
     
         18 . The trolley of  claim 1 , wherein the inner layer and/or outer layer of the core is provided with aluminum and/or glass fibers, which are impregnated with resin. 
     
     
         19 . The trolley of  claim 1 , wherein the plastic comprises polyurethane. 
     
     
         20 . The trolley of  claim 1 , wherein the inner layer and the outer layer each comprise aluminum. 
     
     
         21 . A method for producing a trolley, the method comprising:
 providing a rectangular blank, the blank with a core covered on either side with an inner layer and an outer layer, respectively,   forming two weakened lines in the blank by removing a respective cutout from the inner layer,   placing the blank in a mold,   forming a plastic rim along a peripheral edge of the blank with the mold such that the plastic surrounds the peripheral edge of the blank, and   folding the blank along the weakened lines to form a U-shaped panel, which forms bottom wall and the side walls.   
     
     
         22 . The method of  claim 21 , and further comprising connecting a door to at least one of the walls and forming guides for supporting serving trays on the door on an inner side facing an interior of the housing when the door is in a closed position.
