Abstract
Abstract A keyholder for retaining keys in a bundle comprises a disc-shaped body consisting of two interconnected body halves with a recessed groove having a narrow slot opening circumferentially formed therein and adapted to receive head portions of key retainers which project through the slot opening. A slide cavity extends centrally through the body so as to intersect the circumferential groove with openings provided at opposite ends of the body to permit insertion of the key retainers into the circumferential groove. A slide of a length to fit the slide cavity length is resiliently centered in the slide cavity so as to block the openings in its center position but has an operating structure accessible through a window in one side of the disc member which permits sliding of the slide out of the center position in either direction so as to permit clearing of either of the openings for insertion or removal of key retainers into or from the circumferential groove.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A keyholder for retaining keys in a bundle, said keyholder comprising a disc-shaped body having a circumferential recessed groove formed therein, said groove having a slot-type opening and being adapted to receive head portions of key retainers which project through the slot-type opening, a slide cavity extending centrally through said disc-shaped body and intersecting said circumferential groove with openings provided at opposite ends of said disc-shaped body such that the head portions of said key retainers may be inserted into said circumferential groove through said openings and a slide disposed in said slide cavity, said slide having a length corresponding to the length of said slide cavity extending through said body and being resiliently centered therein so as to block said openings and means for moving said slide out of its center position in said slide cavity in one or the opposite direction thereby clearing either one or the other of said openings for permitting a key retainer's insertion into, or removal from, said groove.
Claim 2
Dependent Claim
165 words
A keyholder for retaining keys in a bundle, said keyholder comprising a disc-shaped body having a circumferential recessed groove formed therein, said groove having a slot-type opening and being adapted to receive head portions of key retainers which project through the slot-type opening, a slide cavity extending centrally through said disc-shaped body and intersecting said circumferential groove with openings provided at opposite ends of said disc-shaped body such that the head portions of said key retainers may be inserted into said circumferential groove through said openings and a slide disposed in said slide cavity, said slide having a length corresponding to the length of said slide cavity extending through said body and being resiliently centered therein so as to block said openings and means for moving said slide out of its center position in said slide cavity in one or the opposite direction thereby clearing either one or the other of said openings for permitting a key retainer's insertion into, or removal from, said groove.
Claim 3
Dependent Claim
22 words
A keyholder according to claim 1, wherein said disc-shaped body consists of two disc halves mounted together along a central separation plane.
Claim 4
Dependent Claim
51 words
A keyholder according to claim 2, wherein at least one of said disc halves has an elongated window formed therein so as to expose a portion of said slide and said slide has an integral operating structure projecting into said window for moving said slide in said one or opposite direction.
Claim 5
Dependent Claim
27 words
A keyholder according to claim 3, wherein the height of said operating structure on said slide corresponds to the thickness of the wall of said disc half.
Claim 6
Dependent Claim
76 words
A keyholder according to claim 2, wherein said slide has stepped trough sections formed therein with a center trough section of greater width than the adjacent trough end sections, a coil-type compression spring is disposed in said central trough section and one of said disc halves has pegs projecting therefrom into said trough end sections adjacent opposite ends of said spring so as to resiliently retain said slide in the center position within said body cavity.
Claim 7
Dependent Claim
51 words
A keyholder according to claim 5, wherein said pegs are recessed inwardly from the inner wall of said circumferential groove a distance corresponding to the thickness of the end face walls of said slide so as to permit sliding of said slide with either end completely out of said circumferential groove.
Claim 8
Dependent Claim
42 words
A keyholder according to claim 1, wherein said disc halves have nesting strips formed at the inner boundary of said recessed grooves, said nesting strips projecting toward, and being shaped so as to engage, one another upon assembly of said disc halves.
Claim 9
Dependent Claim
