Abstract

For fixing a rigid plate (10) on a fixing surface (12), a pad (18) mounted on the fixing surface (12) through the agency of a flat adhesive joint (20) is disposed in a cavity (14) on the underside of the plate (10). The pad (18) is joined at its centroid to the plate (10). Thereby a tilting moment acting on the plate (10) is transformed into a lifting force acting on the pad (18) in a direction perpendicular to the adhesive joint (20).

Claims

1. Apparatus for removably attaching a rigid plate, with an object attached thereto, to a support surface comprising:

(a) said rigid plate having a transverse extension engageable with said support surface and providing a cavity, said extension having an edge at said support surface;

(b) a pad in the cavity of said rigid plate having a central region;

(c) a connector joining the central region of said pad to said plate;

(d) a body in said cavity having a surface thereof facing said pad and a surface thereof remote from said pad;

(e) said body having adhesive on said remote surface thereof; and

(f) means for connecting said pad to said body;

whereby, said connector joining said central region of said pad to said plate and said means for connecting said pad to said body causes substantially only a lifting force on said pad and body perpendicular to said remote surface when said plate is subjected to a force tending to tilt said plate about said edge thereof.

2. Apparatus according to claim 1, wherein said pad has a centroid, said connecter joining said pad at its centroid to the plate.

3. Apparatus according to claim 1, wherein the pad has at least one mirror-symmetry axis, and said connector joins said plate along said mirror-symmetry axis.

4. Apparatus according to claim 1, wherein said connector is a detachable connector for detachably joining the plate and the pad.

5. Apparatus according to claim 4, wherein said connector is a threaded coupling element.

6. Apparatus according to claim 5, and further comprising a stop on said pad remote from said body engaging said plate for limiting the movement of the pad in the cavity.

7. Apparatus according to claim 1, wherein said connector, pad and plate are shaped to permit swiveling movement of said pad relative to said plate.

8. Apparatus according to claim 1, wherein said adhesive comprises means for permitting detachment and reattachment of said body to said support surface without soiling or damaging said support surface.

9. Apparatus according to claim 1, wherein said body is flexible to enable removal of said body by peeling action.

10. Apparatus according to claim 1, wherein said connecting means comprises elements enabling said pad and body to be interlockingly attached to each other.

11. Apparatus according to claim 1, wherein said connecting means comprises interlocking elements on said pad and said body permitting separation thereof by relative parallel movement and preventing separation by a force generally perpendicular to said pad and body.

12. Apparatus according to claim 11, wherein said interlocking elements are of L-shape.

13. Apparatus according to claim 1, wherein said connecting means comprises a hook-and-loop fastener.

14. Apparatus according to claim 1, and further comprising a linear support element extending from said rigid plate opposite said cavity.

15. Apparatus for removably attaching a rigid plate, with an object attached thereto to a support surface comprising:

(a) said rigid plate having a transverse extension engageable with said support surface and providing a cavity, said extension having an edge at said support surface;

(b) a pad in the cavity of said rigid plate having a central region;

(c) a connector joining the central region of said pad to said plate;

(d) a body in said cavity having a surface thereof facing said pad and a surface thereof remote from said pad;

(e) said body having adhesive on said remote surface thereof; and

(f) means for connecting said pad to said body for transmitting to said body a force imparted to said central region of said pad by said connector from said plate, which force is substantially perpendicular to said support surface,

whereby when said plate is subjected to a force tending to tilt said plate about said edge, there will be applied on said pad and body a force perpendicular to said remote surface.
