Abstract

A back plate includes an upper portion, a lower surface defining a plane, a first side, a second side, a plurality of first static attachment elements configured to releasably connect to legs of the compression device, and a plurality of second static attachment elements configured to releasably connect to legs of the compression device. Each of the first and second sides can include one of the plurality of first static attachment elements and one of the plurality of second static attachment elements. The distance between one of the plurality of second static attachment elements on the first side and one of the plurality of second static attachment elements on the second side is greater than a distance between one of the plurality of first static attachment elements on the first side and one of the plurality of first static attachment elements on the second side.

Claims

wherein each of the first and second sides comprises one of the plurality of first static attachment elements and one of the plurality of second static attachment elements;

wherein a distance between the one of the plurality of second static attachment elements on the first side and the one of the plurality of second static attachment elements on the second side is greater than a distance between the one of the plurality of first static attachment elements on the first side and the one of the plurality of first static attachment elements on the second side.

2. The back plate of claim 1, wherein the plurality of first static attachment elements and the plurality of second static attachment elements are formed as integral portions of the back plate.

3. The back plate of claim 1, wherein the plurality of first static attachment elements and the plurality of second static attachment elements are formed separately from the back plate.

4. The back plate of claim 3, wherein the plurality of first static attachment elements and the plurality of second static attachment elements are shafts.

5. The back plate of claim 4, wherein the shafts are connected to portions of the back plate via fasteners.

6. The back plate of claim 1, wherein the back plate comprises glass reinforced crystalline plastic.

7. The back plate of claim 1, wherein the lower surface comprises a plurality of ribs that run from the first side to the second side, and wherein the plane is defined in part by the plurality of ribs.

8. The back plate of claim 1, wherein a distance from the plane to the plurality of second static attachment elements is greater than a distance from the plane to the plurality of first static attachment elements.

9. The back plate of claim 1, wherein each of the first side and the second side has a curved shape away from the plane.

10. A mechanical compression system, comprising:

a back plate comprising an upper portion, a first side, a second side, a plurality of first static attachment elements, and a plurality of second static attachment elements, wherein each of the first and second sides comprises one of the plurality of first static attachment elements and one of the plurality of second static attachment elements; and

a compression device comprising a main portion, a first leg rotatably attached to the main portion, and a second leg rotatably attached to the main portion;

wherein the first leg is configured to be releasably connected to one of the plurality of first static attachment elements on the first side and the second leg is configured to be releasably connected to one of the plurality of first static attachment elements on the second side in a first configuration, and wherein the second leg is configured to be releasably connected to one of the plurality of second static attachment elements on the first side and the second leg is configured to be releasably connected to one of the plurality of second static attachment elements on the second side in a second configuration;

wherein an area bounded by the upper portion, the first leg, the upper portion, and the second leg is larger in the second configuration than in the first configuration.

11. The mechanical compression system of claim 10, wherein the compression device further comprises a piston configured to extend toward the upper portion of the back plate.

12. The mechanical compression system of claim 11, wherein a distance from the piston to the upper portion is greater in the second configuration than in the first configuration.
