Abstract

Abstract A coupling device comprises a multi-directional adjuster with one end clamped at a first center rod and the other at a connection kit; the adjuster further comprises a fixed and a movable clamping block disposed at each end of a main body, a cross slot and a clamping stud arranged at an outer end of the movable clamping block, and a head ferrule formed at the clamping stud. The connection kit further contains a coupling and a connecting sleeve; one end of the coupling is connected to the multi-directional adjuster via the clamping stud and one end of the connecting sleeve is extended to form a connecting rod whereto a limitation piece and two cotton washers are female-jointed externally for locking a cymbal and whereon two parallel faces are formed to be plugged in the sleeve of the coupling to facilitate tight locking of two locking bolts.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 321 words
A coupling device for clamping more cymbals, wherein extra cymbals can be added to a center rod of cymbal stand if desired, comprising a multi-directional adjuster having one end clamped at a first center rod and the other at a connection kit, wherein the multi-directional adjuster further comprises: a main body having a fixed clamping block disposed at its both ends individually; an annular tooth alignment and a through hole are arranged in an inner ring and in center of the fixed clamping block respectively; a pair of movable clamping blocks fixedly jointed with the fixed clamping blocks respectively; a through hole is centered in the movable clamping block; an annular tooth alignment is arranged peripherally around the through hole so as to engage with the tooth alignment of the fixed clamping block; and a cross-slot is formed at another end of each the movable clamping block opposite to the through hole; and a pair of clamping studs penetrating through the through hole of both the fixed clamping block and the moveable clamping block respectively; a wing nut is used to lock the fixed and the movable clamping block together, and each the clamping stud has a head ferrule; the connection kit further comprising: a coupling having a sleeve at one end; a pair of locking bolts are positioned oppositely in surface of the sleeve for locking a connecting sleeve; and the coupling is fixedly clamped at the multi-directional adjuster by taking advantage of the clamping stud; and the connecting sleeve having a thread portion at one end and a pair of locking bolts positioned oppositely, and another end of the connecting sleeve is extended to form a connecting rod to be sleeve-jointed with a limitation piece as well as two cotton washers for locking a cymbal; and two parallel faces are formed on the connecting rod to facilitate propping the locking bolts of the sleeve tightly against the connecting rod.
Claim 2
Dependent Claim 321 words
A coupling device for clamping more cymbals, wherein extra cymbals can be added to a center rod of cymbal stand if desired, comprising a multi-directional adjuster having one end clamped at a first center rod and the other at a connection kit, wherein the multi-directional adjuster further comprises: a main body having a fixed clamping block disposed at its both ends individually; an annular tooth alignment and a through hole are arranged in an inner ring and in center of the fixed clamping block respectively; a pair of movable clamping blocks fixedly jointed with the fixed clamping blocks respectively; a through hole is centered in the movable clamping block; an annular tooth alignment is arranged peripherally around the through hole so as to engage with the tooth alignment of the fixed clamping block; and a cross-slot is formed at another end of each the movable clamping block opposite to the through hole; and a pair of clamping studs penetrating through the through hole of both the fixed clamping block and the moveable clamping block respectively; a wing nut is used to lock the fixed and the movable clamping block together, and each the clamping stud has a head ferrule; the connection kit further comprising: a coupling having a sleeve at one end; a pair of locking bolts are positioned oppositely in surface of the sleeve for locking a connecting sleeve; and the coupling is fixedly clamped at the multi-directional adjuster by taking advantage of the clamping stud; and the connecting sleeve having a thread portion at one end and a pair of locking bolts positioned oppositely, and another end of the connecting sleeve is extended to form a connecting rod to be sleeve-jointed with a limitation piece as well as two cotton washers for locking a cymbal; and two parallel faces are formed on the connecting rod to facilitate propping the locking bolts of the sleeve tightly against the connecting rod.
Claim 3
Dependent Claim 32 words
