Abstract
An antenna coupling enabling the antenna to be quickly detached but incorporating a lock to forestall theft.
Claims24
A coupling for a vehicle-mounted antenna for coupling the antenna to a base mount attached to a part of the vehicle while permitting detachment of the antenna and comprising:
- a shell member having an internal recess;
- a stud member having a first portion disposed in said recess and a second portion extending axially thereof;
- said members being relatively moveable and respectively having means carried thereby enabling the coupling to be attached to the base mount and enabling the antenna to be attached to the coupling;
- one of said members having a lock pin fixed thereto separably securing the members;
- a release member carried by the member not having the pin, said release member having a surface presenting a plurality of openings for receiving the pin, each opening including a stop means preventing the separation of the shell and stud members when the pin is aligned therein;
- and said release member having a slot therein which, when the pin is aligned therewith, is permissive of the separable members being separated along with the antenna carried by one of the separated members, whereby knowledge of the location of the slot allows quick separation but lack of knowledge requires hunting for the slot.

- a shell member having an internal recess;
- a stud member having a first portion disposed in said recess and a second portion extending axially thereof;
- said members being relatively moveable and respectively having means carried thereby enabling the coupling to be attached to the base mount and enabling the antenna to be attached to the coupling;
- one of said members having a radially extending lock pin fixed thereto separably joining the members;
- a rotatable release member surrounding the other two members and having a circumferential groove in which the pin normally resides,
- said release member also having a plurality of openings spaced about the groove for receiving the pin, each opening including a stop means preventing the separation of the stud and shell members when the pin is aligned therein;
- said release member having an axial slot therein which, when the pin is aligned therewith, is permissive of the shell and stud members being separated along with the antenna carried by one of the separated members, whereby knowledge of the location of the slot allows quick separation but lack of knowledge requires hunting for the slot;
- and
- spring means biasing the release member normally to a position where the groove is aligned with the pin.
