Abstract

A lever device includes an elongated body and a double-sided stretch releasing adhesive attached to the body, whereby the body can be firmly adhesively bonded to a surface and cleanly removed from the surface without damaging the surface by stretching the adhesive. The device may include a base, a body member pivotally connected with the base, and stretch releasing adhesive arranged to attach the base and/or body member to a surface or object. The base may be pivotally connected with an end of the body member or to the middle of the body member.

Claims

1. A lever device, comprising:

(a) an elongated body member;

(b) a double-sided stretch releasing adhesive attached to said body.

2. A lever device as defined in claim 1, wherein said body member is rigid and includes a first end portion, a middle portion, and a second end portion, at least one of said first and second end portions comprising a handle.

3. A lever device as defined in claim 2, wherein said device further includes a base portion pivotally connected with said body member.

4. A lever device as defined in claim 3, wherein said stretch releasing adhesive is affixed to said base portion.

5. A lever device as defined in claim 3, wherein said base portion is pivotally connected with said middle portion.

6. A lever device as defined in claim 5, further comprising a head pivotally connected with said first end portion.

7. A lever device as defined in claim 6, wherein said stretch releasing adhesive is affixed to said head.

8. A lever device as defined in claim 7, further comprising biasing means arranged between said base and said body member second end portion for urging said second end portion.

9. A lever device as defined in claim 3, wherein said base portion is pivotally connected with said first end portion.

10. A lever device as defined in claim 9, wherein body member includes a force application portion extending outwardly from said body member.

11. A lever device as defined in claim 2, wherein said stretch releasing adhesive is affixed to said middle portion.

12. A lever device as defined in claim 11, wherein said stretch releasing adhesive is a pair of elongated strips longitudinally spaced and arranged transversely with respect to the longitudinal axis of said body member.

13. A lever device as defined in claim 12, wherein said middle portion includes a planar surface for receiving said adhesive strips.

14. A method of producing torque with a lever device including an elongated body member, comprising the steps of

(a) attaching the body member to a surface using a double-sided stretch releasable adhesive;

and

(b) applying a force to the body member parallel to the surface and perpendicular to the body member to produce torque.
