Abstract

A handle. The handle can include a main body and a pivoting head having a substantially trapezoidal prism shape and pivotally coupled with the main body about a pivot axis. The pivoting head can have a first end including a first limit member and a second end including a second limit member, and each of the first and second limit members can include first and second surfaces, the first surface limiting movement of the pivoting head to a first position and the second surface limiting movement of the pivoting head to a second position. A pivot spring can interact with the main body to bias the pivoting head into the first position.

First claim

What is claimed is:

1. A handle, the handle comprising:
a main body;
first and second arms connected to the main body;
a pivoting head being comprised of at least two mating parts, wherein at least one of the two mating parts is a cover member and at least another one of the at least two mating parts is a base member, wherein the cover member comprises a bearing recess and is attached to the base member, wherein the base member comprises a channel, the pivoting head being coupled with the main body via the first and second arms which connect to the pivoting head utilizing sliding pins at a distal end of the first and second arms that insert into the bearing recess of the cover member and being pivotable about a first pivot axis passing through the sliding pins of the first and second arms and further being pivotable relative to the main body about a second pivot axis;
a pivot spring comprising a first coil spring, a second coil spring, and a main bar portion offset from the first coil spring and the second coil spring, wherein the main bar portion couples the first and second coil springs together in a spaced relationship;
wherein the main bar portion is at least partially disposed in the channel to bias the pivoting head into a rest position; and
wherein the first pivot axis is perpendicular to the second pivot axis.

2. The handle of claim 1 , wherein the first coil spring defines a first coil axis and the second coil spring defines a second coil axis, and wherein the first coil axis is coaxial with the second coil axis.

3. The handle of claim 1 , wherein the first coil spring defines a first coil axis and the second coil spring defines a second coil axis, wherein the first coil axis is coaxial with the second coil axis, and wherein the first pivot axis is parallel to one of the first coil axis and the second coil axis.

4. The handle of claim 1 , wherein the first coil axis and the second coil axis are each parallel to and offset from the first pivot axis a distance of from about 1 mm to about 5 mm.

5. The handle of claim 1 , wherein the pivoting head is pivotable about the first pivot axis from the rest position through an angle of rotation to an angle of between about 0 degrees and about 45 degrees and when pivoted, the pivot spring applies a biasing torque about the first pivot axis of up to about 25 N-mm.

6. The handle of claim 1 , wherein the pivoting head is pivotable about the first pivot axis from the rest position through an angle of rotation to an angle of between about 0 degrees and about 45 degrees and when pivoted, the pivot spring applies a biasing torque about the first pivot axis of between about 2 N-mm and about 12 N-mm.

7. The handle of claim 1 , wherein the pivot spring is made of a metal selected from the group consisting of steel and stainless steel.

8. A handle comprising:
a main body;
at least one arm connected to the main body;
a pivoting head being comprised of at least two mating parts, the at least two mating parts being a cover member and a base member, wherein the cover member comprises a bearing recess and the base member comprises a channel, the pivoting head being coupled with the main body via the at least one arm which connects to the pivoting head utilizing a sliding pin at a distal end of the at least one arm that inserts into the bearing recess of the cover member and being pivotable about a first pivot axis passing through the sliding pin of the at least one arm and further being pivotable relative to the main body about a second pivot axis;
a pivot spring comprising at least one coil spring coupled to a main bar portion, the at least one coil spring comprising a coil axis and the main bar portion comprising a main bar axis, such that the main bar axis is always outside the coil axis;
wherein the main bar portion is at least partially disposed in the channel and the main bar axis is parallel to and offset from the pivot axis; and,
wherein the first pivot axis is perpendicular to the second pivot axis.

9. The handle of claim 8 , wherein the first pivot axis is parallel to the coil axis.

10. The handle of claim 8 , wherein coil axis is parallel to and offset from the first pivot axis by a distance of about 1 mm to about 5 mm.

11. The handle of claim 8 , wherein the pivoting head is pivotable about the first pivot axis from a rest position through an angle of rotation to an angle of between about 0 degrees and about 45 degrees and when pivoted, the pivot spring applies a biasing torque about the first pivot axis of from about 2 N-mm to about 25 N-mm.

12. The handle of claim 8 , wherein the pivot spring comprises stainless steel having an engineering yield stress of between about 800 MPa and about 2000 MPa.

13. The handle of claim 8 , wherein the base member comprises a face comprising an elastomeric material.
