Abstract
Abstract Mobile radio equipment, which must be located in a receptacle in a vehicle, is provided with an arrangement that facilitates the inserting, locking, and removing of the equipment. The arrangement includes a handle rotatably mounted on the front of the equipment. The handle is provided with two cams, one an inserting and locking cam and the other a removing cam. The receptacle is provided with two fixed surfaces, one an inserting and locking surface and the other a removing surface. When the handle is rotated in one direction, the inserting and locking cam engages the inserting and locking surface so that the equipment is pulled into the receptacle and can be locked. When the handle is rotated in the opposite direction, the removing cam engages the removing surface on the receptacle and pulls the equipment out of the receptacle.

Claim 1
Independent Claim
253 words
An improved arrangement for inserting radio equipment and the like in a receptacle and for removing radio equipment and the like from a receptacle, said improved arrangement comprising: a. a fixed member positioned on the front of an equipment receptacle, said fixed member having a first opening bounded on one side by a first inserting and locking surface facing toward the rear of said equipment receptacle, and said fixed member further having a first removing surface facing toward the front of said equipment receptacle; b. a first pivot mounted on the front of equipment to be inserted in and removed from said equipment receptacle, said first pivot providing rotation about an axis transverse to the direction of insertion and removal; c. a first operating handle mounted on said first pivot for rotation thereabout; d. a first inserting and locking cam attached to said first operating handle, said first inserting and locking cam having a surface that rotates about said axis, and that engages said first inserting and locking surface and pulls said equipment into said equipment receptacle in response to said first operating handle being rotated in one direction about said axis; e. and a first removing cam attached to said first operating handle, said first removing cam having a surface that rotates about said axis, and that engages said first removing surface and pulls said equipment out of said equipment receptacle in response to said first operating handle being rotated in a second direction about said axis and opposite said first direction.
