GAS SPRING

PURPOSE: To surely retain a part supported by a gas spring by providing a lock device for removably locking a casing to a covering tube at an intermediate position in which the casing is partially drawn out from the covering tube at a terminal position. CONSTITUTION: When the guide and lock pin 14 of a lock device 13 is inserted against the force of a compression coil spring 17 in the lateral direction with respect to a central axis 6, a lock portion 25 is slip off of a lock hole 23 or 24 and a guide portion 26 reaches the area of the hole 23 or 24. Then, since the width (c) of the portion 26 is slightly smaller than the width (a) of a guide slit 22, a covering tube 10 can be moved over the center interval (I) between the holes 23, 24 in the direction of an axis 6 relative to the casing 2 of a gas spring 1. When the pin 14 is again released, the portion 26 is pushed again into the lock position of one of the holes 23, 24 by the spring 17. Thus, the casing 2 is locked with the tube 10 while ...

A latch mechanism is disclosed for use with an air damper assembly. The air damper assembly is used for controlling the dampening rate of an openable object and includes a piston head having a molded channel therein and a lip seal member disposed around the connecting member of the piston head to form a continuous seal therebetween. The piston head is formed of a pair of axially spaced-apart first and second circular plate members which are connected by the connecting member.

Reverse air damper with latching mechanism

The damper (10) includes a piston assembly (14) which travels within a cylindrical damper housing (12) between an extended position and a retracted position. A transverse channel (28) is formed proximate to the open end of the damper housing (12). A latching diamond (30) travels within the transverse channel. The piston assembly (14) includes a piston shaft (52) with a camming wall sub-assembly formed thereon which engages the latching diamond (34) so that the piston assembly (14) is latched in a "push-push" configuration in the extended position. In this latched configuration, the latching diamond (34) is detent engaged by a concave detent apex (122) formed on an island which includes a longitudinally chamfered portion. Additionally, the flexibility of the island (92) in which the concave detent apex (122) is formed may be increased by transverse passageways or "cored-out" areas (128) in the piston shaft immediately adjacent to the island. While the open latched configuration is normally released by incrementally extending and then releasing the piston assembly, it is possible that a user will attempt to release the open latched configuration by urging the piston assembly toward the retracted position. In this case, the island flexes and the latch diamond travels over a longitudinally chamfered portion of the concave detent apex free of damage to the island, the latch diamond, and other portions of the damper.

Rifle support

The present invention relates to a telescoping leg for a firearm such as a rifle. The leg includes a pair of telescopically slidable elongated members. The first member is configured to be fixed to the stock of a rifle. The second member is telescopically slidable relative to the first member between a retracted position and an extended position. The leg also includes a biasing means to bias the second member towards the extended position and a damper means for damping the movement of the second member between the retracted and extended positions. In one form, one of the first member and the second member is a casing having an inner surface defining in part a gas chamber, the other one of the first member and the second member is a piston received at least partially in the casing for reciprocation along an axis between the retracted and extended positions. The biasing means includes a compressible gas contained in the chamber that yieldably biases the piston towards the extended position. The present invention is advantageous in that when fixed to the butt of the stock of a rifle the leg provides a means of supporting at least part of the weight of the rifle, in particular the weight of the butt and the stock of the rifle, on a surface. The invention is particularly suitable for use with a rifle to which a bipod is mounted towards the front of the stock of the rifle. The invention enables a user to provide stable and controlled changes to the elevation of the rifle on a target and to maintain the elevation of the rifle for an extended period of time while reducing the burden on the user to support the weight of the rifle.
