Abstract

A portable saw table for supporting a portable saw. The portable saw table has a base supporting a plate slidably mountable thereon, and the portable saw is attached to the plate. An adjustable work support is mounted on the base adjacent the plate, and an extendable work support is slidably mounted with respect to the base. Linear guides mounted between the base and the plate properly locate the plate with respect to the adjustable work support, thereby permitting a saw fence to be aligned with a vertical guide surface on the adjustable work support. A locking device is used to secure the plate at its aligned position. The adjustable work support is movable lengthwise to align a horizontal work surface immediately adjacent a saw table, and the adjustable work support is also movable in a vertical direction so that it is coplanar with the saw table. The extendable work support is movable in three mutually perpendicular directions to align it with the adjustable work support. An extendable end support is movable lengthwise and vertically with respect to the extendable work support.

Claims

1. A portable saw table for supporting a portable saw, the portable saw table comprising:

2. The portable saw table of claim 1 wherein the adjustable work support surface is adjustable in a substantially vertical direction.

3. The portable saw table of claim 1 wherein the adjustable work support surface is adapted to be adjustable to a position immediately adjacent the portable saw.

4. The portable saw table of claim 1 wherein the extendable work support is adjustable substantially horizontally along a length of the base.

5. The portable saw table of claim 4 wherein the extendable work support has a substantially horizontal, extendable work support surface, and the extendable work support surface is adjustable to a position substantially aligned with the adjustable work support surface of the adjustable work support.

6. The portable saw table of claim 5 wherein the extendable work support surface is adjustable in a substantially vertical direction.

7. The portable sawtable of claim 5 further comprising an extendable end support mounted with respect to the extendable work support and adjustable along a length of the extend able work support.

8. The portable saw table of claim 7 wherein the extendable end support has a substantially horizontal, extendable end surface, and the extendable end surface is adjustable to a position substantially aligned with the extendable work support surface of the extendable work support.

9. The portable saw table of claim 8 wherein the extendable end surface is adjustable in a substantially vertical direction.

10. The portable saw table of claim 8 wherein the extendable end support has a stop surface substantially perpendicular to a length of the extendable workpiece support.

11. A portable saw table for supporting a portable saw having a substantially vertical saw fence, the portable saw table comprising:

12. The portable sawtable of claim 11 wherein the plate is adjustable with respect to the adjustable work support and is adapted to bring the saw fence in a substantially aligned relationship with the vertical guide surface of the adjustable work support.

13. The portable saw table of claim 12 wherein the extendable fence is adjustable to bring the extendable fence in a substantially aligned relationship with the vertical guide surface of the adjustable work support.

14. The portable saw table of claim 13 wherein the extendable fence is adjustable substantially horizontally in a direction substantially perpendicular to a length of the base.

15. The portable saw table of claim 11 further comprising:

16. The portable saw table of claim 15 wherein the base comprises a tubular main beam and the extendable work support is mounted to slide in one end of the tubular main beam.

17. The portable saw table of claim 15 further comprising a first glide disposed between the tubular main beam and the extendable work support.

18. The portable saw table of claim 17 wherein the extendable work support comprises a tubular middle beam and the extendable end support is mounted to slide in one end of the tubular middle beam.

19. The portable saw table of claim 18 further comprising a second glide disposed between the tubular main and middle beams.

20. The portable saw table of claim 19 wherein the extendable end support comprises a tubular inner beam.

21. The portable saw table of claim 15 further comprising two pairs of legs connected to the base at spaced apart locations along a length of the base, the pairs of legs supporting the base at a desired elevation.

22. The portable saw table of claim 21 wherein the pairs of legs are movable between a folded position and an unfolded position.

23. The portable saw table of claim 21 wherein one of the pair of legs has a wheel rotatably attached to each leg.

24. The portable saw table of claim 21 wherein the pairs of legs have an inverted V-shape.

25. A portable saw table for supporting a portable saw, the portable saw table comprising:

26. The portable saw table of claim 25 wherein the plate is movable substantially horizontally in a direction substantially perpendicular to a length of the base.

27. The portable saw table of claim 25 further comprising a locking device for securing the plate at a desired position with respect to the base.

28. The portable saw table of claim 27 further comprising a locking screw threadedly mounted in one of the linear guides and movable into and out of contact with the plate.

29. The portable saw table of claim 28 wherein the pair of linear guides and the opposed edges of the plate form a dovetail joint.

30. The portable saw table of claim 28 further comprising a pair of locking screws, each of the locking screws being threadedly mounted in one of the linear guides, the locking screws being movable into and out of contact with the plate.
