Abstract

A locking pin for a mount for receiving a T-rail includes a bolt for engagement with the mount, a plurality of facets defined on the bolt, and a locking leaf spring having a first end fixed to the mount and a second distal end with a planar lip. A movable and lockable handle for a portable light includes a hand grip, a pair of arms and a pair of hinges. A locking flange in the hinge securely captures the arm in a folded configuration. The arm is moved out from behind the locking flange and rotated to a fully deployed configuration and held by a detent flange. The handle is attached to the mount provided with the locking pin.

First claim

We claim:

1 . A locking pin for a mount for receiving a T-rail comprising:
a bolt for disposition into and engagement with the mount for capturing the T-rail in the mount; a plurality of facets defined on the bolt; and a locking leaf spring having a first end fixed to the mount and a second distal end with a planar lip, where the bolt contacts the lip and depresses the leaf spring as the bolt is advanced into the mount until the lip and one of the plurality of facets have sufficient clearance between the facet and lip to allow the leaf spring to clear the bolt, the leaf spring then being released so that the lip and facet are juxtaposed parallel to each other and in an interference fit preventing further rotation of the bolt and hence preventing the bolt from being removed from the mount.

2 . The locking pin of claim 1 where the bolt has an octagonal bolt head on which the plurality of facets are defined.

3 . The locking pin of claim 1 where the bolt is threaded and a threaded bore hole is defined in the mount for receiving the bolt.

4 . The locking pin of claim 1 where the lip is angled end surface of the leaf spring.

5 . The locking pin of claim 4 where the angled end surface is directed toward the mount.

6 . The locking pin of claim 1 further comprising a retaining wire coupling the bolt to the mount.

7 . A movable and lockable handle for a portable light comprising:
a hand grip; a pair of arms extending from the hand grip, at least one of the pair of arms being manually and resiliently flexible; and a pair of hinges coupled to the light, the pair of arms being rotatably coupled to corresponding ones of the pair of hinges, at least one of the pair of hinges having a locking flange defined therein for securely capturing the resiliently flexible arm when the arm is disposed in a folded configuration, the resiliently flexible arm capable of being manually flexed from an original form and moved out from behind the locking flange to allow the resiliently flexible arm to be rotated from the folded configuration to a fully deployed configuration.

8 . The movable and lockable handle of claim 7 where the locking hinge has defined thereon a detent flange, and a shoulder extending between the detent flange and the locking flange to provide an edge on which the resiliently flexible arm rides from an edge of the locking flange onto the shoulder and to resiliently return to its original form as it is rotated to the fully deployed configuration and to become seated behind the detent flange.

9 . The movable and lockable handle of claim 8 where the detent flange provides a resistance interference fit with the resiliently flexible arm to maintain the handle in the fully deployed configuration, but to allow manual rotation of the handle in the locking hinge from the fully deployed configuration toward the folded configuration upon the application of a predetermined manual torque to the handle.

10 . The movable and lockable handle of claim 7 further comprising a pair of identical handles provided for the light, each having a corresponding hand grip, pair of arms and pair of hinges, one handle of the pair of handles coupled to each side of the light.

11 . The movable and lockable handle of claim 7 where the hand grip is molded to form an ergonomic finger grip.

12 . The movable and lockable handle of claim 7 further comprising a fingerhold defined in the resiliently flexible arm to facilitate manual engagement with the resiliently flexible arm to move it out from behind the locking flange of the locking hinge.

13 . The movable and lockable handle of claim 7 where only one of the pair of hinges comprises a locking hinge.

14 . The movable and lockable handle of claim 7 where both of the pair of hinges comprises a locking hinge.

15 . The movable and lockable handle of claim 7 further comprising a receiving mount for a T-rail coupled to the light and where the pair of hinges are fixed to the mount.

16 . The movable and lockable handle of claim 15 further comprising a locking pin for the mount for receiving a T-rail.

17 . The movable and lockable handle of claim 16 where the locking pin comprises:
a bolt for disposition into and engagement with the mount for capturing the T-rail in the mount;
a plurality of facets defined on the bolt; and
a locking leaf spring having a first end fixed to the mount and a second distal end with a planar lip, where the bolt contacts the lip and depresses the leaf spring as the bolt is advanced into the mount until the lip and one of the plurality of facets have sufficient clearance between the facet and lip to allow the leaf spring to clear the bolt, the leaf spring then being released so that the lip and facet are juxtaposed parallel to each other and in an interference fit preventing further rotation of the bolt and hence preventing the bolt from being removed from the mount.

8 . The locking pin of claim 17 where the lip is an angled end surface of the leaf spring.

19 . The locking pin of claim 18 where the angled end surface is directed toward the mount.

20 . The movable and lockable handle of claim 7 further comprising a mount coupled to the light and where the portable light comprises a search light capable of being mounted to a gun or vehicle.
