Abstract
Abstract A quick release locking mechanism suitable for use as a cymbal retainer includes an adaptor threadably enageable on a cymbal support rod. A collar member adjustably positionable along the adaptor has a tapered socket aperture for accommodating a spherical keeper element. A locking ring surrounding the collar includes a circumferential camming surface rotationally displaceable for selectively urging the spherical element into engagement with the adaptor to secure the collar. An eccentric channel portion provides a pocket for receiving the spherical element to release the collar.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
119 words
In a cymbal mounting arrangement including a cymbal rod having a threaded end, a cymbal having a central opening for passage of the cymbal rod and support means for suspending the cymbal on said rod, the improvement comprising a quick release locking mechanism, said locking mechanism having an adaptor threadably engageable on said cymbal rod, a collar member slidably mounted on said adaptor, said collar member including an aperture for seating a locking ball, a ring member rotationally displaceable about said collar member, said ring member including a camming surface for selectively urging said locking ball toward the adaptor for interlocking engagement therewith to thus secure the collar at selected locations along the adaptor for adjustable cymbal vibration dampening.
Claim 2
Dependent Claim
119 words
In a cymbal mounting arrangement including a cymbal rod having a threaded end, a cymbal having a central opening for passage of the cymbal rod and support means for suspending the cymbal on said rod, the improvement comprising a quick release locking mechanism, said locking mechanism having an adaptor threadably engageable on said cymbal rod, a collar member slidably mounted on said adaptor, said collar member including an aperture for seating a locking ball, a ring member rotationally displaceable about said collar member, said ring member including a camming surface for selectively urging said locking ball toward the adaptor for interlocking engagement therewith to thus secure the collar at selected locations along the adaptor for adjustable cymbal vibration dampening.
Claim 3
Dependent Claim
30 words
A quick release locking mechanism as claimed in claim 1 wherein the ring member includes a recessed surface area selectively registrable with the locking ball for releasing the collar member.
Claim 4
Dependent Claim
145 words
A quick release locking mechanism for removably mounting a cymbal to a support comprising an adaptor member extendible through a central opening in said cymbal, a collar member surrounding said adaptor member and slidably positionable therealong, said collar member including an aperture in a wall and providing communication with said adaptor member, a keeper element accommodatable within said aperture, a ring member circumscribing said collar member and in confronting relationship with said keeper element, said ring member further having a camming surface, said ring member being rotationably displaceable about said collar member with the camming surface contacting and urging the keeper element toward the adaptor member, said adaptor member defining a plurality of spaced annular ridges for receiving said keeper element at incremental ridge locations therealong whereby the collar member can be adjustably positioned against the cymbal and releasably secured by the rotatable ring member.
Claim 5
Dependent Claim
145 words
A quick release locking mechanism for removably mounting a cymbal to a support comprising an adaptor member extendible through a central opening in said cymbal, a collar member surrounding said adaptor member and slidably positionable therealong, said collar member including an aperture in a wall and providing communication with said adaptor member, a keeper element accommodatable within said aperture, a ring member circumscribing said collar member and in confronting relationship with said keeper element, said ring member further having a camming surface, said ring member being rotationably displaceable about said collar member with the camming surface contacting and urging the keeper element toward the adaptor member, said adaptor member defining a plurality of spaced annular ridges for receiving said keeper element at incremental ridge locations therealong whereby the collar member can be adjustably positioned against the cymbal and releasably secured by the rotatable ring member.
Claim 6
Dependent Claim
29 words
A quick release locking mechanism as claimed in claim 3 wherein the ring member has a central opening with the circumferential wall of said opening providing said camming surface.
Claim 7
Dependent Claim
21 words
A quick release locking mechanism as claimed in claim 4 wherein a portion of said circumferential wall defines an eccentric channel.
Claim 8
Dependent Claim
38 words
A quick release locking mechanism as claimed in claim 5 wherein the eccentric channel is selectively registrable with the keeper element, the eccentric channel further providing a recess for accommodating the keeper element to release the collar member.
Claim 9
Dependent Claim
44 words
A quick release locking mechanism as claimed in claim 6 wherein the collar member includes a tapered aperture, said aperture being adapted for accommodatingly receiving said keeper element with a portion of said keeper element being projectable through a tapered end of said aperture.
Claim 10
Dependent Claim
28 words
A quick release locking mechanism as claimed in claim 7 wherein the collar member includes a tubular segment having a flange for receiving and positioning the ring member.
Claim 11
Dependent Claim
41 words
A quick release locking mechanism as claimed in claim 8 wherein a portion of the adaptor in confronting relationship with the cymbal includes an integral protective sleeve of a thermoplastic material, said sleeve further including retainer means for supporting the cymbal.
Claim 12
Dependent Claim
32 words
A quick release locking mechanism as claimed in claim 9 wherein the upper end of the adaptor is provided with a square head which can be engaged by a conventional drum key.
Claim 13
Dependent Claim
37 words
A quick release locking mechanism as claimed in claim 10 wherein the collar member is provided with an annular groove and clip means for engaging the annular groove to secure the ring member to the collar member.
Claim 14
Dependent Claim
16 words
A quick release locking mechanism as claimed in claim 11 wherein the keeper element is spherical.
