Fixture for radio frequency identification tag
The present disclosure relates to a fixture and, more particularly, to a fixture which holds a radio frequency identification tag and methods of use. The structure includes a cage comprising a top portion, a bottom portion attached to the top portion and a storage space between the top portion and the bottom portion; a moveable linkage system extending within the storage space; a door attached to a first end of the linkage system, the door being moveable between an open position and a closed position; and a cam mechanism comprising structures with surfaces that permit the door to move from the closed position to the open position and to prevent the door from closing when in the closed position.
1 . A structure comprising:
a cage comprising a cavity with conductive material to shield the cavity from electromagnetic waves;
a linkage system comprising different apertures and which is moveable between a first position within the cavity and a second position extending outside of the cavity;
a door attached to the linkage system and which slides between an open position and a closed position; and
an cam mechanism attached to the linkage system which is structured to hold the door in the open position exposing the cavity and to allow closure of the door into the closed position thereby enclosing the cavity, the cam mechanism being adjustable by placing a protuberance within the different apertures of the linkage system.
2 . The structure of claim 1 , wherein the cam mechanism is movable by one of a hydraulic system, pneumatic system and an electromechanical system.
3 . The structure of claim 1 , wherein the cam mechanism comprises a first structure linearly moveable with the linkage system and a second structure vertically moveable with a spring loaded mechanism.
4 . The structure of claim 3 , wherein the first structure slides along the second structure during movement of the door from the closed position to the open position.
5 . The structure of claim 4 , wherein the first structure rests against the second structure to prevent the door from moving from the opened position to the closed.
6 . The structure of claim 1 , further comprising a spring coupled between the linkage system and the cage, the spring exerting a force to close the door when the spring loaded mechanism is depressed and the second structure is moved vertically away from the first structure.
7 . A structure comprising:
a cage comprising conductive material to shield an interior portion from electromagnetic waves;
a linkage system moveable between a first position and a second position, the second position extending outside of the cage;
a handle attached to a first end the linkage system by extending through a slot within the cage, the handle further configured to slide within the slot and linearly move the linkage system between the first position and the second position;
a door attached to a second end of the linkage system and which is linearly slidable between an open position and a closed position;
a button moveable vertically, orthogonal to the linkage system;
a spring loaded mechanism coupled to the linkage system and the cage; and
a cam mechanism comprising a first structure and a second structure, the first structure coupled to the linkage system and linearly moveable and the second structure coupled to the button and vertically moveable.
