Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
A one-piece, plastic pick-guard for shielding the tip of a medical pick or the like, comprising a pair of elongate jaws integrally hinged together at one of their ends for pivotal movement between open and closed positions, one of said jaws having a pair of transversely aligned, laterally spaced upstanding latches, the other jaw having a pair of transversely aligned, laterally spaced, latch-receptive openings therethrough, a transverse latch strike on the said other jaw at one side of and spanning each of said latch-receptive openings, and a deformable, resilient pad secured to and carried by said first mentioned jaw, adjacent and in circumscribing relationship with the lower or jaw-adjacent ends of the latches, said laterally spaced latches defining the sides of a longitudinally extending pick-receptive channel.
Claim 2
Dependent Claim
126 words
A one-piece, plastic pick-guard for shielding the tip of a medical pick or the like, comprising a pair of elongate jaws integrally hinged together at one of their ends for pivotal movement between open and closed positions, one of said jaws having a pair of transversely aligned, laterally spaced upstanding latches, the other jaw having a pair of transversely aligned, laterally spaced, latch-receptive openings therethrough, a transverse latch strike on the said other jaw at one side of and spanning each of said latch-receptive openings, and a deformable, resilient pad secured to and carried by said first mentioned jaw, adjacent and in circumscribing relationship with the lower or jaw-adjacent ends of the latches, said laterally spaced latches defining the sides of a longitudinally extending pick-receptive channel.
Claim 3
Dependent Claim
69 words
A device as called for in claim 1, wherein the jaw in which the latch-receptive openings are located includes an elongate, centrally disposed through opening which extends longitudinally of said jaw in spaced relationship with the latch-receptive openings therethrough and the hinged end thereof, said elongate, longitudinal opening providing visual access to the contents of the guard during those periods of time when the jaws are in closed position.
Claim 4
Dependent Claim
23 words
A device as called for in claim 1, wherein the pick-guard and the deformable, resilient pad are each of a non-pyrogenic, autoclavable material.
Claim 5
Dependent Claim
61 words
A device as called for in claim 1, wherein the deformable, resilient pad includes a pair of transversely aligned, laterally spaced, latch-receptive slots therethrough which define a snug, slip-fit relationship with the lower or jaw-adjacent ends of the latches, and wherein the said first mentioned jaw includes a cavity intermediate said latches and in open communication with the deformable, resilient pad.
Claim 6
Dependent Claim
77 words
A device as called for in claim 1, which includes a pair of transversely aligned, laterally spaced abutments secured to, carried by and projecting from the free end of the jaw in which the latch-receptive openings are located, and in longitudinal alignment with the latches; and a pair of complementary spacers integral with and forming part of the hinge, wherein the abutments and spacers define contact points between the jaws when said jaws are in closed position.
Claim 7
Dependent Claim
33 words
A device as called for in claim 1, wherein each of the jaws includes an elongate, longitudinally extending chamber intermediate the latches and the hinge and in open communication with the pick-receptive channel.
Claim 8
Dependent Claim
28 words
A device as called for in claim 1, wherein the free end of the said first mentioned jaw is forward of the free end of the other jaw.
