Abstract

Abstract For releasably interconnecting a first member and a second member such as, for example, a neck band or strap having a depending chain or the like and a musical instrument such as a saxophone there is provided a coupling device comprising a housing to which the chain is connected, opposed closure members being mounted within the housing with adjacent end portions of the closure members being resiliently urged by the inherent resiliency of the closure members towards a closed condition in which the saxophone is connectible thereto. A manually operable actuating member is mounted on the housing and is movable between a first position in which a portion of the actuating member which is of frusto-conical form, permits the adjacent end portions of the closure members to attain the closed condition, and a second position in which the frusto-conical portion of the actuating member urges the closure members to an open condition of the above-mentioned adjacent end portions thereof against the influence of the resilient urging of the closure members.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 189 words
A coupling device comprising a housing to which a first member is connectible, opposed resilient closure members mounted in the housing with adjacent end portions of said closure members being urged by the inherent resiliency of the closure members towards a closed condition in which a second member is connectible thereto, and an actuating member mounted on the housing and movable between a first position in which the actuating member permits said adjacent end portions of the closure members to attain said closed condition under the influence of said inherent resiliency of the closure members, and a second position in which the actuating member extends between and is in contact with the closure members to maintain said adjacent end portions thereof in an open condition against the influence of said inherent resiliency of the closure members, the actuating member having opposed cam faces for urging the closure members against said inherent resiliency of the closure members from said closed condition to said open condition of said adjacent end portions of the closure members on said movement of the actuating member from said first position to said second position thereof.
Claim 2
Dependent Claim 189 words
A coupling device comprising a housing to which a first member is connectible, opposed resilient closure members mounted in the housing with adjacent end portions of said closure members being urged by the inherent resiliency of the closure members towards a closed condition in which a second member is connectible thereto, and an actuating member mounted on the housing and movable between a first position in which the actuating member permits said adjacent end portions of the closure members to attain said closed condition under the influence of said inherent resiliency of the closure members, and a second position in which the actuating member extends between and is in contact with the closure members to maintain said adjacent end portions thereof in an open condition against the influence of said inherent resiliency of the closure members, the actuating member having opposed cam faces for urging the closure members against said inherent resiliency of the closure members from said closed condition to said open condition of said adjacent end portions of the closure members on said movement of the actuating member from said first position to said second position thereof.
Claim 3
Dependent Claim 85 words
A coupling device according to claim 1, wherein the housing is provided with an aperture through which the actuating member is disposed for manual movement thereof from said first position to said second position thereof, the actuating member having a shoulder which is in abutting contact with the portion of the housing adjacent to said aperture when the actuating member is in said first position thereof to prevent movement of the actuating member from said first position in a direction away from said second position.
Claim 4
Dependent Claim 56 words
A coupling device according to claim 1, wherein the opposed closure members are reflexly directed at said adjacent end portions thereof, for urging of said adjacent end portions to said open condition thereof by a force applied thereto in a direction towards the actuating member when said adjacent end portions are in said closed condition thereof.
Claim 5
Dependent Claim 37 words
A coupling device according to claim 1, wherein the housing is provided with a slot having an open end and within which said adjacent end portions of the closure members are disposed when in said closed condition.
Claim 6
Dependent Claim 46 words
A coupling device according to claim 1 wherein the ends of the opposed closure members remote from said adjacent end portions thereof are integrally interconnected, the closure members being mounted in the housing by securement of said remote ends of the closure members to the housing.
