Abstract

In order to provide a desk in which a component can be commonly used for top plates of various different specifications, the desk is so constructed that a frame 2 which supports a top plate 3 comprises a plurality of frame members 21, 22, 23 and at least a part of the frame members 21, 22, 23 are provided with rail grooves 21a, 22a, 23a as a longitudinally continuous mounting portion and a certain position of the rail grooves 21a, 22a, 23a is selected, and a mounting member 4 through 7 for mounting a component such as optional components or a top plate 3 can be held at the position.

Claims

1. A desk comprising a top plate, having a top and an underside, leg support posts supporting the top plate, and a frame connecting upper ends of the leg support posts, the frame comprising a plurality of frame members arranged adjacent to the underside of the top plate, but with a space formed between the top plate and the frame, wherein

at least a part of the frame members are provided with a longitudinally continuous mounting portion wherein a position on said mounting portion can be selected, and a mating mounting member can be held at said position for mounting a component;

and

wherein a part of the mounting member can be extended to a position near an edge of the top plate at which the component is mounted.

2. The desk of claim 1 wherein said mounting portion has a rail groove that is open continuously at an upright wall of said frame, and a base end of said mounting member can make an engagement with said rail groove.

3. The desk of claim 2 wherein said mounting member comprises a bracket having a mounting face, a liner member which is arranged at a base end of said bracket and a screw which is helically connected with said liner member passing through the bracket, wherein said mounting member can be fixed by steps of arranging the base end of the bracket affixed to an outer face of said upright wall, arranging said liner member affixed to an inner face of said upright wall in the rail groove, and helically connecting said screw which has passed through the bracket with the liner member so that the upright wall can be held between the bracket and the liner member.

4. The desk of claim 3 wherein said liner member can make an abutting contact with the inner faces by extending over the inner faces of the upright walls wherein the liner member is positioned by passing through an opening of the rail groove then rotating to a predetermined angle.

5. The desk of claim 4 wherein the frame comprises right and left side frame members, a front frame member connecting front ends of each side frame members and a reinforcing frame member connecting centers of each right and left side frame members, wherein at least the side frame members and the front frame member are made of a material extruded to have an isometric cross-section wherein a rail groove is made to open inwardly at an upright wall of the frame members.

6. The desk of claim 3 wherein the frame comprises right and left side frame members, a front frame member connecting front ends of each side frame members and a reinforcing frame member connecting centers of each right and left side frame members, wherein at least the side frame members and the front frame member are made of a material extruded to have an isometric cross-section wherein a rail groove is made to open inwardly at an upright wall of the frame members.

7. The desk of claim 2 wherein the frame comprises right and left side frame members, a front frame member connecting front ends of each side frame members and a reinforcing frame member connecting centers of each right and left side frame members, wherein at least the side frame members and the front frame member are made of a material extruded to have an isometric cross-section wherein a rail groove is made to open inwardly at an upright wall of the frame members.

8. The desk of claim 7 wherein the reinforcing frame member has rail grooves on both upright walls.

9. The desk of claim 8 wherein the reinforcing frame member is mounted on the side frame members by engaging each end of the reinforcing frame member with the corresponding rail groove of the side frame members.

10. The desk of claim 1 wherein the frame comprises right and left side frame members, a front frame member connecting front ends of each side frame members and a reinforcing frame member connecting centers of each right and left side frame members, wherein at least the side frame members and the front frame member are made of a material extruded to have an isometric cross-section wherein a rail groove is made to open inwardly at an upright wall of the frame members.

11. The desk of claim 1 wherein the frame comprises right and left side frame members, a front frame member connecting front ends of each side frame members and a reinforcing frame member connecting centers of each right and left side frame members, wherein at least the side frame members and the front frame member are made of a material extruded to have an isometric cross-section wherein a rail groove is made to open inwardly at an upright wall of the frame members.
