Aluminum-extruded frame structure

Abstract

A frame includes an aluminum-extruded body having top, middle, and bottom sections, which are integrally connected together in a vertical direction. The top section forms a top channel having two spaced racks mounted thereto by webs respectively. Each web defines a slit. The bottom section forms a bottom cannel having two spaced side wall extending therefrom, and each side wall forms a rib. The top and bottom sections are connected by the middle section therebetween and sideways extend beyond the middle section to form a slot for receiving and holding a slide rail therein. The ribs and the slits are formed and positioned in such a way that the ribs of the frame are slidably engageable with the slits of an identical frame positioned just under the frame so as to expand the frame.

1 . A frame comprising an aluminum-extruded body comprising top, middle, and bottom sections, which are integrally connected together in a given direction, the top section forming a top channel having two spaced racks mounted thereto by webs respectively, each web defining a slit, the bottom section forming a bottom cannel having two spaced side wall extending therefrom, each side wall forming a rib, the top and bottom sections being connected by the middle section therebetween, wherein the ribs and the slits are formed and positioned in such a way that the ribs of the frame are slidably engageable with the slits of an identical frame positioned just under the frame. 
   
   
       2 . The frame as claimed in  claim 1 , wherein the middle section comprises a plurality of consecutive channel integrally connected to each other and the top and bottom sections are mounted to opposite ends of the middle section and sideways extending beyond the middle section to define therebetween a slot adapted to receive and hold a slide rail therein. 
   
   
       3 . The frame as claimed in  claim 1 , wherein the top section is jointed to the bottom section of the identical frame to expand the frame to serve as a partition of adjustable surface area.
