Abstract

A platform device for attaching to a working table includes a pair of rails slidably supported on a base, and a plate slidably supported on the rails. The base includes two grooves for slidably receiving the rails. One or more stops are secured on the base, and two end boards secured to the ends of the rails for selectively engaging with the stops and for limiting the movement of the rail relative to the base. One or more blocks are secured to the plate for selectively engaging with either of the end boards and for limiting the movement of the plate relative to the rail.

Claims

1. A platform assembly for attaching to an object, said platform assembly comprising:

a base,

at least one rail slidably supported on said base,

a first limiting means for limiting a movement of said at least one rail relative to said base,

a plate slidably supported on said at least one rail, and

a second limiting means for limiting a movement of said plate relative to said at least one rail.

2. The platform assembly according to claim 1, wherein said base includes at least one groove formed therein for slidably receiving said at least one rail.

3. The platform assembly according to claim 2, wherein said base includes at least one beam disposed thereon, said at least one groove is formed in said at least one beam for slidably receiving said at least one rail.

4. The platform assembly according to claim 1, wherein said at least one rail includes two ends, said first limiting means includes at least one stop secured on said base, and two end boards secured to said ends of said at least one rail for selectively engaging with said at least one stop.

5. The platform assembly according to claim 1, wherein said at least one rail includes two ends, said second limiting means includes two end boards secured to said ends of said at least one rail, and at least one block secured to said plate for selectively engaging with either of said end boards.

6. The platform assembly according to claim 5, wherein said at least one block includes a duct formed therein for slidably receiving said at least one rail.

7. The platform assembly according to claim 6, wherein said at least one rail is slidably engaged in said duct of said at least one block with a dovetail-and-dovetail slot engagement.

8. The platform assembly according to claim 1, wherein said plate includes two ends each having a panel secured thereto, said panels each includes an opening formed therein for slidably receiving said at least one rail and for guiding said plate to slide along said at least one rail.

9. The platform assembly according to claim 1, wherein said at least one rail is slidably engaged in said base with a dovetail-and-dovetail slot engagement.
