Abstract

A backing device useful in repairing a hole. In some embodiments, the hole is in a wall, for example a relatively large hole in a wall (e.g., vertical wall, ceiling, etc.) of, for example, a home or building structure. The backing device includes a collapsible backing member and adhesive strips. The backing member defines a front face opposite a rear face, and includes first and second panels connected at a hinge segment. The adhesive strips are disposed on the front face. The backing member is foldable from a flat state to a collapsed state for insertion through the wall hole. Once deployed “behind” the wall, the backing member is transitioned to the flat state, and the adhesive strips utilized to secure the backing device to a back surface of the wall. In some embodiments, the backing device, while in the flat state, is relatively rigid in one direction and collapsible in the opposite direction.

First claim

What is claimed is:

1. A backing device for use in repairing a hole in a wall, the backing device comprising:
a collapsible backing member defining a front face and a rear face, the backing member including a central panel, a first outer panel and a second outer panel, wherein the central panel is connected to the first outer panel at a first hinge segment and the second outer panel is connected to the first outer panel at a second hinge segment, and wherein the central panel is wider than either the first or second outer panel; and
first and second adhesive strips disposed on the front face;
wherein the backing member is configured to provide a flat state and is configured to be foldable from the flat state to a collapsed state in a direction of the front face;
wherein the backing member is further configured to be relatively rigid in the flat state in a direction of the rear face; and
wherein each hinge segment includes a stop arrangement on the rear face for inhibiting folding of the hinge segment in the flat state in the direction of the rear face.

2. The backing device of claim 1 , wherein the backing member is an integrally formed, extruded plastic part.

3. The backing device of claim 1 , wherein the backing member defines a passage through a thickness of the central panel configured to receive a user's finger.

4. The backing device of claim 1 , wherein the panels are pop sticks and the hinge segment is formed by a film interconnecting the pop sticks.

5. A kit for repairing a wall hole, the kit comprising:
a backing device of claim 1 and a wall repair compound.

6. The kit of claim 5 , further comprising a cover article configured to be selectively applied to the backing device.

7. The kit of claim 6 , wherein the backing device and the cover article combine to define a support structure for receiving the wall repair compound.

8. The backing device of claim 1 , wherein the collapsed state entails the front face forming a concave curve.

9. The backing device of claim 1 and further comprising a flexible layer extending across at least a portion of the rear face of each of the central and outer panels to thereby interconnect the panels.

10. The backing device of claim 1 , wherein each panel includes a plurality of apertures extending through a thickness of the panel.

11. The backing device of claim 1 , and further comprising a third outer panel connected to the central panel at a third hinge segment.

12. The backing device of claim 11 , and further comprising a fourth outer panel connected to the third panel at a fourth hinge segment.

13. The backing device of claim 1 , wherein first hinge segment defines a first hinge axis, the second hinge segment defines a second hinge axis, and wherein the first hinge axis extends parallel to the second hinge axis.

14. The backing device of claim 1 , wherein the first and second outer panels are separable from one another at the second hinge segment.

15. A backing device for use in repairing a hole in a wall, the backing device comprising:
a collapsible backing member defining a front face and a rear face, the backing member including first and second outer panels and a central panel wider than either the first or second outer panel, wherein the first and second outer panels are connected at a first hinge segment and the first outer panel and central panel connected at a second hinge segment, with each hinge segment including a flexible material extending across at least a portion of the rear face of the panels to interconnect the panels; and
first and second adhesive strips disposed on the front face;
wherein the backing member is configured to provide a flat state and is configured to be foldable from the flat state to a collapsed state in a direction of the front face;
wherein the backing member is further configured to be relatively rigid in the flat state in a direction of the rear face; and
wherein the hinge segment includes a stop arrangement on the rear face for inhibiting folding of the hinge segment in the flat state in the direction of the rear face.

16. The backing device of claim 15 , wherein each panel includes a plurality of passages from the front face to the rear face.

17. The backing device of claim 15 , wherein the backing member defines a passage through a thickness of the central panel configured to receive a user's finger.

18. The backing device of claim 15 , wherein first hinge segment defines a first hinge axis, the second hinge segment defines a second hinge axis, and wherein the first hinge axis extends parallel to the second hinge axis.

19. The backing device of claim 15 , wherein the collapsed state entails the front face forming a concave curve.
