Abstract

An articulating prop to prop panels in an open position is disclosed. In one embodiment, the prop includes a protrusion that rests in a groove to lock members of the articulating prop in position. An external force causes the articulating prop members to rotate into a locked position. In another embodiment, an additional latch is disclosed which further locks the articulating prop in a locked position. An external force causes the articulating prop member to rotate out of a locked position. Shapes and interfaces of handles of the articulating prop are disclosed. Openings and pivotal axes of members of the articulating prop are also disclosed herein.

First claim

The invention claimed is:

1. A locking mechanism for an articulating prop comprising:
a first member comprising a handle, a protrusion, and a first pivotal axis which is pivotally fixed to a first body; and
a second member comprising a groove and a second pivotal axis which is pivotally fixed to a second body, the first member and the second member being joined at an axis of rotation, wherein the axis of rotation allows the protrusion to engage the groove, wherein a first external force in a first direction substantially antinormal to the articulating prop and applied to the handle locks the first member and the second member in position, and wherein a second external force applied in a second direction substantially normal to the articulating prop and applied to the handle unlocks the first member and the second member of mechanism for the articulating prop, and wherein while the first member and the second member are locked in position, a force in a third direction substantially parallel to the articulating prop and applied by the first body or the second body does not unlock the first member and the second member.

2. The locking mechanism for the articulating prop of claim 1 , wherein the first body is a hood of a vehicle.

3. The locking mechanism for the articulating prop of claim 1 , wherein the second body is a vehicle structural frame member.

4. The locking mechanism for the articulating prop of claim 1 , wherein the first pivotal axis of the first member comprises a first opening and the axis of rotation comprises a second opening, the first opening being at an opposed end of the first member to the second opening and the protrusion.

5. The locking mechanism for the articulating prop of claim 4 , wherein the protrusion further comprises a first bolt through a third opening in the first member, the handle being rigidly attached to the first bolt.

6. The locking mechanism for the articulating prop of claim 1 , wherein the second pivotal axis of the second member comprises a first opening and the axis of rotation comprises a second opening, the first opening being on an opposed side of the second member to the second opening.

7. The locking mechanism for the articulating prop of claim 1 , wherein a weight of the first body acts on the groove of the second member through the protrusion of the first member.

8. The locking mechanism for the articulating prop of claim 1 , wherein the first second member further comprises a semi-circular end, the axis of rotation being near the semi-circular end.

9. The locking mechanism for the articulating prop of claim 6 , wherein the second member further comprises a third pivotal axis and a latch, the latch being pivotally fixed to the second member at the third pivotal axis and the latch being shaped to fit a contour of the protrusion.

10. The locking mechanism for the articulating prop of claim 1 , wherein the handle has a general shape selected from the group of shapes consisting of a sphere, a cylinder, a rectangular prism, and a polyhedron.

11. The locking mechanism for the articulating prop of claim 10 , wherein the handle further comprises curved interfaces.

12. The locking mechanism for the articulating prop of claim 1 wherein the axis of rotation comprises an axle.

13. The locking mechanism for the articulating prop of claim 12 , wherein the axle of the axis of rotation further comprises a second bolt and a spacer, the second bolt passing through and pivotally fixing the second member, the spacer, and the first member, the first member and the second member being separated by the spacer.

14. The locking mechanism for the articulating prop of claim 1 , wherein the first member and the second member are comprised at least partially of aluminum, steel, a polymer, carbon fibers, or a combination thereof.

15. The locking mechanism for the articulating prop of claim 1 , wherein the first member and the second member are at least partially manufactured by laser-cutting, water-jet cutting, casting, injection molding, extruding, forging, stamping, milling, or drilling.

16. The locking mechanism for the articulating prop of claim 1 , wherein the groove is circular in shape and the protrusion is cylindrical in shape, the groove having a radius equal to an outer radius of the protrusion.

17. The locking mechanism for the articulating prop of claim 1 , wherein the axis of rotation has a range of motion between −5 degrees and 200 degrees.

18. The locking mechanism for the articulating prop of claim 1 , wherein the first member comprises a dogleg, the axis of rotation extending through at least a portion of the dogleg.
