Abstract: A portable support mount designed for attachment to a shooting rail or other surface in order to support a rifle or other object. The portable support mount attaches to and is held level on a surface by means of a spring clamp and a stabilization bar with bumpers made of rubber attached to the ends of the stabilization bar. The spring clamp is fused to a support tube housing a rod that can vary the height of the mount. On top of the rod is a detachable holding member on which a user places the forend of a rifle while aiming and firing it. In addition, the holding member can be removed from the portable support mount, and the rod can attach to a camera, telescope, small video camera, or other device.

Abstract: A tank retaining bracket having a rotating head for selectively receiving and securing a tank to the bracket having a mounting cup preferably of nylon which adapted to abut and hold a cylindrical tank in an inverted position in a positively engaging manner. The mounting cup includes an arcuate retaining surface and can easily replaced during normal maintenance. The mounting cup is attachable to the rotating head of the bracket frame of a positively engaging tank holder usable with cylindrical tanks such as self-contained breathing apparatus primarily for facilitating adjustability of positioning of retaining of the tank with respect to the mounting bracket. The body member is adjustably movable to a multiple of lateral directions such that it is firmly secured in place by a plurality of fasteners and engagement is further enhanced by a ridge on the rotating frame head and a mated engaging block on the mounting cup.

Abstract: A fixing mechanism for fixing a battery in a sleeve defines a receiving groove therein, a latching member including a body, a restraining flange extending out from one end of the body and a contact end formed at the other end of the body, a latching slot defined in an inner surface of the sleeve, an elastic member compressed and received in the receiving groove and a barrel detachably fixed in the receiving groove. An end of the compressed elastic member resists a bottom surface of the receiving groove and the other end of the elastic member resists the restraining flange, to press the latching member contact end to pass through the barrel and finally to be received in the latching slot, and the restraining flange is blocked by the barrel.
