Microphone stand coupler
First Claim
1. A microphone stand coupler for connecting a threaded microphone stand pole to a microphone stand base having a hole normally for receiving the microphone stand pole, comprising:
- a. a tube having a first end threaded to receive the microphone pole, and a second end adapted to receive a tension shaft;
b. a cam lever movable between a first position and a second position;
c. a tension shaft having a first end pivotably coupled to the cam lever and a second end coupled to the second end of the tube;
d. a collet and spring means interposed between the cam lever and the second end of the tube, for providing a spring force opposing the movement of the cam lever between the first position and the second position;
wherein the microphone stand pole is attachable to the microphone stand base by screwing the microphone stand pole into the first end of the tube, inserting the second end of the tube through the hole of the microphone stand base, and moving the cam lever from the first position to the second position.

Abstract
A microphone stand coupler that facilitates microphone stand assembly and disassembly by enabling users to quickly and easily snap a microphone pole into a microphone stand base. In the preferred embodiment of the present invention, the microphone stand coupler is manufactured with hollow piping that is tapered and closed at one end. The interior of the piping is preferably threaded to accommodate the microphone pole. At the closed and tapered end of the coupler, a threaded hole is provided to accommodate a base attachment merchanism. The coupler is inserted through an opening in the microphone stand base, and the coupler is secured to the base by a over-center cam lever that is part of the base attachment mechanism. A microphone pole may then be threaded into the open end of the microphone stand coupler. The coupler and attached microphone pole may be detached from the base by disengaging the base attachment lever. The invention thus comprises a bayonet-type coupler that permits a microphone pole to be quickly detached from or attached to a microphone stand base.
