Abstract
Abstract A musical instrument support, having an improved slide for adjusting the length of the support and an improved clasp for engaging a musical instrument to be supported is disclosed. The slide is approximately circular in shape and is constructed in a manner to reduce the wearing of a cord which passes through the slide. This is accomplished by utilizing a sleeve which has a lower coefficient of friction than the material from which the slide is made. The cord forms two annular loops around the sleeve. The friction between the annular loops and the sleeve is sufficient to maintain the support at a given length. The clasp is constructed in a manner which reduces the number of moving parts needed to engage and disengage the musical instrument over the prior art thereby simplifying the manufacturing process. In particular, means are provided for disengaging the musical instrument from the clasp, which means comprises only a spring, two retractable jaws and a plunger having an end of predetermined extent which a support ring on the instrument may bear against, thereby compressing the spring and retracting the jaws.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
367 words
In a musical instrument support having a neck engaging loop member adapted to be worn around the neck of a human being, a cord coupled to each of two ends of said neck engaging loop member, and a clasp adapted to engage said cord, said clasp disposed at an end of said support opposite said neck engaging loop member, the improvement comprising: a slide adapted to slidingly and frictionally engage said cord, said slide disposed intermediate the ends of said support; said slide comprising a substantially round body portion having a first channel disposed within said slide, adapted to receive said cord coupled to one end of said neck engaging loop, a second channel disposed within said slide, adapted to receive said cord coupled to the other end of said neck engaging loop, an annular loop portion disposed intermediate said first channel and said second channel, and adjacent to each of said channels, a substantially cylindrical sleeve adjacent to and encircling an inner surface of said annular loop portion, a cavity disposed intermediate said first channel and said second channel, said cavity adapted to receive said cord and to retain a portion of said cord; a clasp adapted to engage said cord, said clasp disposed at an end of said support opposite said neck engaging loop member; said clasp comprising a body portion having a cutout defined on one end thereof, two retractable jaws, each of said jaws normally extending into said cutout from opposite sides thereof, a spring disposed within said body portion adapted to urge said jaws to extend into said cutout, a plunger disposed within said body portion adapted to compress said spring and urge said jaws to a retracted position when a predetermined pressure is applied to said plunger in a direction opposite said cutout, said plunger having an end which extends into said cutout, which end has a predetermined extent; whereby the length of said support is adjustable by the action of said slide and a musical instrument may be removably coupled to said clasp by the action of said jaws, said predetermined pressure applied to said plunger at said end of predetermined extent which extends into said cutout, and said spring.
Claim 2
Dependent Claim
367 words
In a musical instrument support having a neck engaging loop member adapted to be worn around the neck of a human being, a cord coupled to each of two ends of said neck engaging loop member, and a clasp adapted to engage said cord, said clasp disposed at an end of said support opposite said neck engaging loop member, the improvement comprising: a slide adapted to slidingly and frictionally engage said cord, said slide disposed intermediate the ends of said support; said slide comprising a substantially round body portion having a first channel disposed within said slide, adapted to receive said cord coupled to one end of said neck engaging loop, a second channel disposed within said slide, adapted to receive said cord coupled to the other end of said neck engaging loop, an annular loop portion disposed intermediate said first channel and said second channel, and adjacent to each of said channels, a substantially cylindrical sleeve adjacent to and encircling an inner surface of said annular loop portion, a cavity disposed intermediate said first channel and said second channel, said cavity adapted to receive said cord and to retain a portion of said cord; a clasp adapted to engage said cord, said clasp disposed at an end of said support opposite said neck engaging loop member; said clasp comprising a body portion having a cutout defined on one end thereof, two retractable jaws, each of said jaws normally extending into said cutout from opposite sides thereof, a spring disposed within said body portion adapted to urge said jaws to extend into said cutout, a plunger disposed within said body portion adapted to compress said spring and urge said jaws to a retracted position when a predetermined pressure is applied to said plunger in a direction opposite said cutout, said plunger having an end which extends into said cutout, which end has a predetermined extent; whereby the length of said support is adjustable by the action of said slide and a musical instrument may be removably coupled to said clasp by the action of said jaws, said predetermined pressure applied to said plunger at said end of predetermined extent which extends into said cutout, and said spring.
Claim 3
Dependent Claim
15 words
The musical instrument support defined by claim 1 wherein said sleeve is comprised of aluminum.
Claim 4
Dependent Claim
26 words
The musical instrument support defined by claim 1 wherein said portion of said cord received and retained by said cavity comprises a knot in the cord.
