Abstract

The present disclosure relates generally to a bi-directional clamp system and method of use. More particularly, a bi-directional clamp with two clamp bars and two clamping assemblies are described herein. The clamp assemblies have a plurality of arms freely movable in response to a material load is described herein.

First claim

What is claimed:

1 . A system for clamping material, said system comprising:
a first clamp bar extending in a transverse manner, a second clamp bar parallel to the first clamp bar extending in a transverse manner; a first clamp assembly operatively coupled to the first clamp bar and the second clamp bar; a second clamp assembly operatively coupled to the first clamp bar and the second clamp bar; wherein each the first clamp bar and second clamp bar have a plurality of clamp arms; and wherein the system is operative to apply force to four sides of a material desired to be clamped.

2 . The system of claim 1 , wherein the plurality of clamp arms are angled.

3 . The system of claim 2 , wherein the plurality of clamp arms are angled at an angle greater than 90 degrees and less than 180 degrees.

4 . The system of claim 3 , wherein the plurality of clamp arms are angled at an angle greater than 120 degrees and less than 160 degrees.

5 . The system of claim 1 , wherein the first clamp assembly comprises:
an upper clamp; a lower clamp; and a clamping foot operatively connected to the upper clamp and lower clamp.

6 . The system of claim 5 , further comprising:
a threaded member in operative connection with the clamping foot and pivot bushing, wherein the pivot bushing has an aperture in which the threaded member is threaded within.

7 . The system of claim 6 , further comprising:
a handle operatively connected to the threaded member at a first end and the clamping foot at the second end, wherein rotation of the handle in a first direction is operative to move the threaded member and thereby the clamping foot in a direction towards the material.

8 . The system of claim 5 , wherein the clamping foot is of an H-shape.

9 . The system of claim 1 , wherein the second clamp assembly is operative to be disengaged from the first and second rail.

10 . The system of claim 5 , wherein the first clamp bar and second clamp bar contain a plurality of apertures.

11 . The system of claim 10 , wherein the first clamp assembly is attached by a first engagement placed through an aperture in the first and third clamp arms to the first clamp bar and a second engagement placed through an aperture in the second and fourth clamp arms to the second rail bar.

12 . The system of claim 11 , wherein the second clamp assembly comprises:
an upper clamp; a lower clamp; and a clamping foot operatively connected to the upper clamp and lower clamp.

13 . The system of claim 12 , wherein the second clamp assembly is attached by a first removable engagement placed through an aperture in the fifth and seventh clamp arms to the first clamp bar and a second removable engagement placed through an aperture in the sixth and eighth clamp arms to the second rail bar.

14 . The system of claim 1 , wherein the first clamp bar and second clamp bar may be interchanged with a third clamp bar and a fourth clamp bar that are of different length than the first clamp bar and second clamp bar.

15 . A method for clamping work material comprising:
loading work material between a first clamp bar with a bottom surface and a second clamp bar with a top surface; contacting the work material with the bottom of the first clamp bar and the top surface of the second clamp bar; abutting the work material with a clamping foot on a first clamp assembly; further abutting the work material with a clamping foot on a second clamp assembly; and applying force to four sides of the work material by the bottom surface of the first clamp bar, top surface of the second clamp bar, the clamping foot on the first clamp assembly and the clamping foot on the second clamp assembly.

16 . The method of claim 15 , wherein further abutting further comprises:
attaching the second clamp assembly to first and second clamp bar.

17 . The method of claim 15 , wherein prior to loading:
removing the second clamp assembly.

18 . The method of claim 15 , wherein the abutting further comprises:
rotating a handle in engagement with the clamping foot to bring the clamping foot in engagement with the material.

19 . The method of claim 15 , wherein further abutting further comprises:
attaching the second clamp assembly at an aperture of the first clamp bar via a removable pin; and further attaching the second clamp assembly at an aperture of the second clamp bar via a removable pin.

20 . The method of claim 15 , wherein loading further comprises:
placing a piece of further material above or below the work material to abut at least one of the first clamp bar or second clamp bar if the material has a thickness of less than ⅜ of an inch.

21 . The method of claim 15 , wherein loading further comprises:
placing a piece of further material to a side of the work material to abut at least one of the clamping foot on the first clamp assembly or second clamp assembly.

22 . A method for applying force to a work material comprising:
loading work material between a first clamp bar with a bottom surface and a second clamp bar with a top surface; abutting the work material with a first clamping foot on a first clamp assembly; applying a first horizontal force with the clamping foot to a first side of the work material; contacting a second side of the work material with a second clamping foot on a second clamp assembly; applying a second horizontal force with the clamping foot to a second side of the work material; applying a first vertical force with the bottom surface of the first clamp bar on a top surface of the work material; and applying a second vertical force with the top surface of the second clamp bar on a bottom surface of the work material.

23 . The method of claim 22 , simultaneously to applying the first horizontal force further comprising:
moving clamp arms on the first clamp assembly in response to a thickness of the material.
