Abstract

Redetachable, self-adhesive hook or similar fixing device having a baseplate, characterized by a strip of a double-sided adhesive film which is such that the bond obtained with it can be separated again by pulling on it so as to stretch it, which film carries on its front face the baseplate and with its rear face is bonded to a substrate, the separation of the bonded baseplate of the fixing device together with the strip from the substrate taking place by rotation of the baseplate essentially in the plane of the bond.

Claims

1. Redetachable, self-adhesive fixing device, comprising

a) a baseplate,

b) a strip of double-sided adhesive film having a front face and a rear face, said adhesive film being of a kind which, when adhesively attached to a substrate forms a bond without curing which can be broken by stretching said adhesive film,

the front face of said film being attached to said baseplate, and being fully-covered by said baseplate to which it is attached, and wherein said device, when adhesively attached to a substrate by said rear face of said double-sided adhesive film, is detachable from said substrate without leaving any residues or causing damage by rotation of said baseplate essentially in the plane of said substrate.

2. Fixing device according to claim 1, wherein said baseplate has a thickness of less than 5 mm.

3. Fixing device according to claim 1, wherein said baseplate is provided with at least one groove.

4. Fixing device according to claim 1, wherein said strip has substantially the same shape as said baseplate.

5. Fixing device according to claim 1, wherein the adhesion of the adhesive film is less than the cohesion, the adhesion largely disappears when the film is extended, and the ratio of peel force to tear load is at least 1:

1.5.

6. Fixing device according to claim 1, wherein said adhesive film comprises a thermoplastic rubber and tackifying resins, and said adhesive film has a high elasticity and a low plasticity.

7. Fixing device according to claim 1, wherein said rear face of said strip is covered with a release laminate before bonding to the substrate.

8. Fixing device according to claim 1, wherein said fixing device and said baseplate consist of plastic.

9. Fixing device according to claim 1, wherein said fixing device and said baseplate consist of metal.

10. Fixing device according to claim 1, wherein said baseplate is provided with at least one bore.

11. Fixing device according to claim 1, wherein said baseplate is provided with at least one groove and at least one bore.
