Aluminum-extruded frame structure
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. Field of the Invention
The present invention relates generally to a frame serving as a partition or a support that holds a slide rail of for example a withdrawable support tray or a work cart, and in particular to an aluminum-extruded frame that can be easily coupled or jointed to each other for expansion.
2. The Related Art
A lot of devices that use slide rails are available in the market, such as work carts or a withdrawable support tray, as shown in
Thus, the present invention is aimed to overcome the drawback and ensure assembling and operation efficiency of slide rails.
SUMMARY OF THE INVENTIONAn objective of the present invention is to provide a frame that is made of aluminum extrusion and having top and bottom sections having means to releasably joint each other for expansion of the frame and the top and bottom sections forming a slot therebetween for receiving and retaining a slide rail therein to simplify the installation of the slide rail.
To realize the above objectives, in accordance with the present invention, there is provided a frame comprising 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.
The present invention will be apparent to those skilled in the art by reading the following description of a preferred embodiment thereof, with reference to the attached drawings, in which:
With reference to the drawings and in particular to
Also referring to
To install a slide rail 2 of a work cart, as shown in
To this point, it is apparent that the present invention features the following advantages:
(1) The frame of the present invention can be easily manufactured and installed, and can cooperate with slide rails for withdrawable members, incorporated in fore example a work cart or a support tray to simplify the installation operation of the slide rails.
(2) The frame of the present invention can function as a partition board for it can be easily expanded by jointing consecutive ones of the frame to suit the requirement for covering any area or space and is thus flexible.
Although the present invention has been described with reference to the preferred embodiment with reference to the drawings thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
Claims
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.
