Abstract

The invention provides unique releasable adhesive devices that are high-load bearing and highly stable while allowing adjustment of the weight-bearing angle in a wide range, thereby greatly expanding the scope of applications for technology. Adhesive systems and devices of the invention can be designed to fit applications ranging from household weight-bearing shelves and holders, components for transportation, athletic equipment, labels and advertising posts, automobile interior trims, permanent or reversible fasteners, as well as instruments and devices for industrial, commercial, medical or military applications.

First claim

What is claimed is:

1. A releasable surface-adhesive device comprising:
a first adhesive pad having a first adhering surface on at least one side for adhering to a first target surface;
a second adhesive pad having a second adhering surface on at least one side for adhering to a second target surface;
a tether attached to and extending between the first adhesive pad and the second adhesive pad; and
a hinge attached to the tether at a location between the first and second adhesive pads.

2. The releasable surface-adhesive device of claim 1 , wherein the first adhesive pad, second adhesive pad, and the tether form a single continuous planar component.

3. The releasable surface-adhesive device of claim 1 , wherein the first adhering surface and the second adhering surface are located on a first side of the tether.

4. The releasable surface-adhesive device of claim 1 , wherein the first adhering surface and the second adhering surface are located on opposing sides of the tether.

5. The releasable surface-adhesive device of claim 1 , further comprising a handle connected to the hinge.

6. The releasable surface-adhesive device of claim 1 , wherein the first adhesive pad comprises a first planar backing layer and a first elastic planar layer, wherein the first elastic planar layer forms the first adhering surface on at least one side and the first elastic planar layer is applied to the first planar backing layer on at least a side opposing the first adhering surface, and wherein the second adhesive pad comprises a second planar backing layer and a second elastic planar layer, wherein the second elastic planar layer forms the second adhering surface on at least one side and wherein the second elastic planar layer is applied to the second planar backing layer on at least a side opposing the second adhering surface.

7. The releasable surface-adhesive device of claim 6 , wherein the first planar backing layer, the second planar backing layer, and the tether are a single continuous layer.

8. The releasable surface-adhesive device of claim 6 , wherein the first planar backing layer has a higher in-plane stiffness than the first elastic planar layer, and wherein the second planar backing layer has a higher in-plane stiffness than the second elastic planar layer.

9. The releasable surface-adhesive device of claim 1 , wherein the hinge is attached away from a center of the tether between the first and second adhesive pads.

10. The releasable surface-adhesive device of claim 1 , further comprising a rigid substrate, wherein the hinge is attached to the rigid substrate and the rigid substrate is attached to the tether.

11. The releasable surface-adhesive device of claim 1 , wherein the tether is attached away from a center of at least one of the first adhesive pad and the second adhesive pad.

12. The releasable surface-adhesive device of claim 1 , wherein the hinge is rotatable along at least one rotational axis to form an angle with the tether between 0° and 359°.

13. A releasable surface-adhesive device comprising:
at least one adhesive pad, wherein each adhesive pad comprises:
a planar backing layer; and
a first elastic planar layer that forms an adhering surface on at least one side and wherein the elastic planar layer is applied to the planar backing layer on at least a side opposing the adhering surface;

a tether attached to the at least one adhesive pad; and
a hinge attached to the tether.

14. The releasable surface-adhesive device of claim 13 , wherein the at least one adhesive pad is at least two adhesive pads, and wherein the hinge is attached to the tether at a location between the at least two adhesive pads.

15. The releasable surface-adhesive device of claim 14 , wherein the at least two adhesive pads include more than two adhesive pads.

16. The releasable surface-adhesive device of claim 14 , wherein the adhering surfaces of the at least two adhesive pads are located on a first side of the tether.

17. The releasable surface-adhesive device of claim 14 , wherein the adhering surfaces of the at least two adhesive pads are located on opposing sides of the tether.

18. The releasable surface-adhesive device of claim 14 , wherein the at least two adhesive pads and the tether form a single continuous planar component.

19. The releasable surface-adhesive device of claim 14 , wherein the hinge is attached away from a center of the tether between the at least two adhesive pads.

20. The releasable surface-adhesive device of claim 13 , further comprising a handle connected to the hinge.

21. The releasable surface-adhesive device of claim 13 , wherein the planar backing layer of the at least one adhesive pad and the tether are a single continuous layer.

22. The releasable surface-adhesive device of claim 13 , wherein the planar backing layer of the at least one adhesive pad has a higher in-plane stiffness than the elastic planar layer of the at least one adhesive pad.

23. The releasable surface-adhesive device of claim 13 , wherein the hinge is rotatable along at least one rotational axis to form an angle with the tether between 0° to 359°.
