Abstract

A work supporting and holding stackable step stool is formed of plastic material, and includes a plurality of vertical and horizontal apertures provided in the step stool body sides for supporting and holding lumber material therewith for providing low and medium height scaffolding, as well as for securely retaining lumber material to be cut, drilled, sanded and the like. Further holes are provided in each step stool for securely holding tubing or pipe to be worked upon. Planar support surfaces provide a user with both steps as well as work supporting surfaces and each step is provided with a shallow V-shaped recess for holding material of round configuration during work thereupon. A raised lip on the upper step on one edge thereof provided with measuring indicia can be used for measuring material to be cut, drilled, and the like. Electric power outlet receptacle structure, a storage box, a pencil sharpener and nail suspension apertures are additional features of the present step stool arrangement.

Claims

1. A device for use by a skilled craftsman comprising:

a formed body of non-corrosive plastic material;

said body configured to provide two planar step surfaces at different heights and two equal sides and two equal ends each having leg extensions for raising the body above a support surface, said two sides and two ends being substantially parallel and with a slight inward and upward taper so that a plurality of the devices can be stacked for storage purposes;

means with at least one of said two planar step surfaces for holding tubular material such as pipe to be worked on; and

further means provided in said sides for holding boards therewith.

2. The device set forth in claim 1, further including additional means for holding pipe through at least two opposite sides of said formed body.

3. The device set forth in claim 2, wherein the uppermost planar step surface is provided along one edge with a scale having units of measurement thereon.

4. The device set forth in claim 3, wherein said scale with units of measurement is mounted on a lip for the purpose of holding material to be cut from sliding off the planar step surface.

5. The device set forth in claim 4, together with at least two holes in at least one side for receiving a common nail in each for the purpose of hanging the device during storage thereof.

6. The device set forth in claim 5, together with an electrical panel mounted in an aperture in a side of the formed body, and further including a main power supply adaptor unit attached to said electrical panel.

7. The device set forth in claim 6, further including a pencil sharpener as part of said electrical panel for use by carpenters in maintaining their carpenter pencils in usable condition.

8. The device set forth in claim 5, wherein an aperture in said formed body holds a storage box during use of said device.

9. The device set forth in claim 2, wherein a lip is provided along one edge of at least one of said planar step surfaces, said lip being provided with units of measurement therealong for convenience of measuring stock to be worked on.

10. The device set forth in claim 2, together with at least two holes in at least one side for receiving a common nail in each for the purpose of hanging the device during storage thereof.

11. The device set forth in claim 2, together with an electrical panel mounted in an aperture in a side of said formed body, and further including a main power supply adaptor unit attached to said electrical panel.

12. The device set forth in claim 2, wherein an aperture in said formed body holds a storage box during use of said device.

13. A multi-purpose support device comprising:

a rectangular body having four sides;

said rectangular body provided with two planar support surfaces at different heights;

each of said sides having a slight taper in the vertical direction so that a plurality of said devices can be stacked one upon another and thereby take up as little storage space as possible;

a plurality of aperture means provided in each of said four body sides for securely retaining a piece of material on which work is to be performed; and

holding means with each of said two planar support surfaces for receiving tube-like material to be worked upon.

14. The device set forth in claim 13, wherein said plurality of aperture means in said body sides include both round and rectangular openings for holding pipe and lumber material, respectively.

15. The device set forth in claim 14, wherein said round openings comprise a plurality of holes having a diameter of 1/2" to 31/2" in graduated sizes for receiving pipe of corresponding sizes.

16. The device set forth in claim 14, wherein said rectangular openings comprise a plurality of vertical apertures as well as horizontal apertures for receiving various sizes of lumber material therein.

17. The device set forth in claim 16, wherein said round openings comprise a plurality of holes having a diameter of 1/2" to 31/2" in graduated sizes for receiving pipe of corresponding sizes, and said device further including at least one handhold and a plurality of small openings for hanging said device from a support nail.

18. The device set forth in claim 14, wherein said holding means with each of said two planar support surfaces includes a relatively shallow V-shaped groove in the top of each support surface.

19. The device set forth in claim 14, wherein said rectangular body having four sides further includes each corner side joint connecting the respective sides having a leg extension for supporting the body at a level substantially above the bottom of each leg.

20. The device set forth in claim 14, together with a lip having indicia thereon provided along one edge of the highest planar support surface.

21. The device set forth in claim 14, together with an electrical power outlet panel including pencil sharpening means mounted in another aperture provided in said device.
