Abstract

A method of applying a tensile or compressive force to a selected location of a work piece or surface without damaging the work piece or the surface and without leaving adhesive residue thereon includes providing a device including a body member and a force applying member movably connected with the body member, attaching the body member and/or the force applying member to the work piece and/or surface using a double-sided stretch releasing adhesive such that one end of the force applying member is adjacent the selected location, and moving the force applying member toward the work piece or surface to generate a compressive force, or moving the force applying member away from the work piece or surface to generate a tensile force.

Claims

1. A method of applying a compressive force to a selected location on a work piece, comprising the steps of:

(a) providing a device including a body member and a force applying member movably connected with the body member;

(b) attaching the body member to a surface using a double-sided stretch releasable adhesive, whereby one end of the force applying member is adjacent the selected location; and

(c) moving the force applying member toward the surface to generate a compressive force.

2. A method as defined in claim 1, further comprising the step of stretching the double-sided stretch releasable adhesive to remove the adhesive from the body member and the surface.

3. A method as defined in claim 1, wherein the surface is formed of a material selected from the group consisting of cellulosic materials and masonry.

4. A method as defined in claim 1, wherein the work piece is a surface.

5. A method as defined in claim 1, wherein the work piece is an object.

6. A method as defined in claim 1, wherein the force applying member is threadably connected with the body member.

7. A method as defined in claim 1, wherein the force applying member is pivotally connected with the body member.

8. A method as defined in claim 1, wherein the force applying member is slidaby connected with the body member, and further wherein the device includes a force generating member arranged to bias the force applying member in the direction of the work piece.

9. A method as defined in claim 8, wherein the force generating member is a spring.

10. A method as defined in claim 1, wherein the device includes a pair of force applying members arranged at an angle.

11. A method of applying a tensile force to a selected location on a work piece, comprising the steps of:

(a) providing a device including a body member and a force applying member movably connected with the body member;

(b) arranging the body member on a surface, whereby one end of the force applying member is adjacent the selected location;

(c) attaching the force applying member to the surface using a double-sided stretch releasable adhesive; and

(d) moving the force applying member away from the surface to generate a tensile force.

12. A method as defined in claim 11, wherein the surface is formed of a material selected from the group consisting of cellulosic materials and masonry.

13. A method as defined in claim 11, wherein the work piece is a surface.

14. A method as defined in claim 11, wherein the work piece is an object.

15. A method as defined in claim 11, wherein the force applying member is threadably connected with the body member.

16. A method as defined in claim 11, wherein the force applying member is pivotally connected with the body member.

17. A method as defined in claim 11, wherein the force applying member is slidaby connected with the body member, and further wherein the device further includes a force generating member arranged to bias the force applying member in the direction of the work piece.

18. A method as defined in claim 17, wherein the force generating member is a spring.

19. A method of removing a dent from a surface, comprising the steps of

(a) providing a device including a body member and a force applying member movably connected with the body member;

(b) arranging the device on the surface such that one end of the force applying member is adjacent the dent;

(c) attaching the force applying member to the dented surface using a double-sided stretch releasable adhesive; and

(d) moving the force applying member away from the surface to generate a pulling force on the dented surface, wherein the pulling force is sufficient to remove the dent.
