Abstract
Abstract An adaptor for removably mounting a hand held type microphone on the end of a shaft of a stand, such as a floor or desk stand, which has a housing defining a cavity and a block of compliant material provided with a recess for receiving the end of the shaft of the stand disposed within the cavity. The block is compressed or deformed within the cavity of the housing by a plunger actuated by a cam to securely lock the housing on the end of the stand shaft. The microphone is attached to the cam, thus providing a swivel mount for the microphone. The adaptor utilizes one swivel position of the cam releasing stress on the compliant block to release the adaptor from the end of the shaft and other positions of the cam to stress the compliant block to engage the end of the shaft.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
280 words
An adaptor for removably mounting a hand held type microphone on the end of a shaft comprising a housing having a first portion and a second portion disposed adjacent thereto, said first portion having a cavity therein with a wall between the first and second portion of the housing and an orifice in the wall between the first and the second portion of the housing, said first portion of the housing also having an opening in the wall thereof communicating with the cavity and adapted to receive the end of the shaft, a cam, means operatively associated with the second portion of the housing for rotatably mounting the cam directly confronting the orifice in the wall of the first portion of the housing, a plunger disposed within the cavity of the first portion of the housing and having a protuberance extending outwardly from the cavity into slidable abutment with the cam, said cam having a first segment of greater diameter and a second segment of lesser diameter in slidable engagement with the protrusion on the plunger, a block of compliant material disposed within the cavity between the plunger and the opening, said block having a recess aligned with and confronting the opening adapted to receive the end of the shaft, a lever mounted on the cam for positioning the cam with the first or second segment thereof in abutment with the plunger, said block being compressed by the plunger when the first segment of the cam engages the plunger and being released from compression when the second segment of the cam engages the plunger, and means mounted on the housing for mounting a hand held type microphone to the housing.
Claim 2
Dependent Claim
280 words
An adaptor for removably mounting a hand held type microphone on the end of a shaft comprising a housing having a first portion and a second portion disposed adjacent thereto, said first portion having a cavity therein with a wall between the first and second portion of the housing and an orifice in the wall between the first and the second portion of the housing, said first portion of the housing also having an opening in the wall thereof communicating with the cavity and adapted to receive the end of the shaft, a cam, means operatively associated with the second portion of the housing for rotatably mounting the cam directly confronting the orifice in the wall of the first portion of the housing, a plunger disposed within the cavity of the first portion of the housing and having a protuberance extending outwardly from the cavity into slidable abutment with the cam, said cam having a first segment of greater diameter and a second segment of lesser diameter in slidable engagement with the protrusion on the plunger, a block of compliant material disposed within the cavity between the plunger and the opening, said block having a recess aligned with and confronting the opening adapted to receive the end of the shaft, a lever mounted on the cam for positioning the cam with the first or second segment thereof in abutment with the plunger, said block being compressed by the plunger when the first segment of the cam engages the plunger and being released from compression when the second segment of the cam engages the plunger, and means mounted on the housing for mounting a hand held type microphone to the housing.
Claim 3
Dependent Claim
66 words
An adaptor comprising the combination of claim 1 wherein the second portion of the housing includes a pair of parallel tongues extending outwardly from the wall of the first portion on opposite sides of the opening therein, and the means for rotatably mounting the cam comprises a pin mounted at opposite ends on the tongues, the cam being provided with a channel journalled about the pin.
Claim 4
Dependent Claim
76 words
An adaptor comprising the combination of claim 2 wherein the cam comprises a flat plate having opposite surfaces confronting opposite tongues respectively, the channel extending normal to the plane of the plate, said cam having a first cylindrical surface coaxial with the pin adapted to slidably abut the protuberance, and said cam having a second surface adjacent to the first surface extending inwardly from the radius of the first surface and adapted to accommodate the protuberance.
Claim 5
Dependent Claim
48 words
An adaptor comprising the combination of claim 3 wherein the protuberance is part cylindrical with the cylindrical axis thereof disposed parallel to the pin, and the second surface of the cam is part cylindrical with the cylindrical axis parallel to and spaced from the axis of the pin.
Claim 6
Dependent Claim
32 words
An adaptor comprising the combination of claim 3 wherein the cam is provided with nipple disposed between the first and second surfaces and extending radially outwardly from the first and second surfaces.
Claim 7
Dependent Claim
41 words
An adaptor comprising the combination of claim 1 wherein the cavity within the first portion of the housing is symmetrical about the axis traversing the center of the aperture and opening and the plunger and unstressed block substantially fill the cavity.
Claim 8
Dependent Claim
34 words
An adaptor comprising the combination of claim 6 wherein the plunger has a flat plate portion of larger cross section than the aperture and the protuberance extends from the plate portion through the aperture.
Claim 9
Dependent Claim
31 words
An adapTor comprising the combination of claim 1 where a clevis for holding a microphone is mounted on the cam, whereby the clevis functions as a lever for positioning the cam.
Claim 10
Dependent Claim
53 words
An adaptor comprising the combination of claim 8 wherein the clevis comprises a part conical portion with a slot disposed on the side opposite the cam for receiving a microphone, the interior surface of said portion having a layer of compliant material of substantially uniform thickness extending toward both sides of the slot.
Claim 11
Dependent Claim
64 words
An adaptor comprising the combination of claim 9 wherein the interior surface of the clevis is provided with a pair of straight grooves, one of said grooves being adjacent to each side of the slot, the layer of compliant material on the interior surface of the clevis extending between the grooves, and a strip of compliant material is disposed within each of the grooves.
