Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
201 words
A separable fastener the components of which are arranged for mounting in confrontable rectangular openings provided in thin wall portions of a pair of relatively movable members, said separable fastener comprising: a. a stud component including a base portion dimensioned to cover the rectangular opening provided in one of the relatively movable members, an opposing pair of yieldable side tabs, an opposing pair of yieldable latch elements in registery with the side tabs, the areas encompassed by the side tabs and latch elements being equal to each other and the area of the opening in the movable member and being movable between a position in registery with the opening and position at right angles thereto wherein the extremities of the side tabs and the extremities of the latch elements frictionally engage opposite surfaces of the movable member to retain the base portion in place; the stud component also including a stud projecting axially from the base portion; b. and a latching sleeve component dimensioned to overly and cover the opening provided in the other of said relatively movable members, and including means for attachment to margins of said opening and a latching sleeve arranged for removable attachment to said stud component.
Claim 2
Dependent Claim
201 words
A separable fastener the components of which are arranged for mounting in confrontable rectangular openings provided in thin wall portions of a pair of relatively movable members, said separable fastener comprising: a. a stud component including a base portion dimensioned to cover the rectangular opening provided in one of the relatively movable members, an opposing pair of yieldable side tabs, an opposing pair of yieldable latch elements in registery with the side tabs, the areas encompassed by the side tabs and latch elements being equal to each other and the area of the opening in the movable member and being movable between a position in registery with the opening and position at right angles thereto wherein the extremities of the side tabs and the extremities of the latch elements frictionally engage opposite surfaces of the movable member to retain the base portion in place; the stud component also including a stud projecting axially from the base portion; b. and a latching sleeve component dimensioned to overly and cover the opening provided in the other of said relatively movable members, and including means for attachment to margins of said opening and a latching sleeve arranged for removable attachment to said stud component.
Claim 3
Dependent Claim
41 words
A separable fastener, as defined in claim 1, wherein: a. said latching sleeve member includes a guard sleeve surrounding the latching sleeve, and opposite sides of the guard sleeve are provided with panels having radially movable extremities forming said attachment means.
Claim 4
Dependent Claim
33 words
A separable fastener, as defined in claim 1, wherein: a. at least one of said components is frictionally slidable laterally with respect to its corresponding opening to permit alignment with the mounting component.
Claim 5
Dependent Claim
29 words
A separable fastener as defined in claim 1, wherein: a. both components are adapted to be received in rectangular openings and are arranged for limited lateral displacement longitudinally therein.
Claim 6
Dependent Claim
28 words
A separable fastener as defined in claim 1, wherein: a. each component is removably received in its respective opening; b. and friction means is provided to resist removal.
Claim 7
Dependent Claim
111 words
A separable fastener the components of which are disposed on confrontable portions of a pair of relatively movable members at least one of which is provided with a component receiving opening, said separable fastener comprising: a. a latching sleeve component including a centrally disposed stud receiving sleeve having radial slits to form a set of radially expansible stud engaging fingers, a surrounding guard sleeve, and an opposed pair of laterally movable latching elements engageable with opposite margins of said opening to secure the latching sleeve component to the corresponding relatively movable member; b. and a stud component secured to the other relatively movable member in position for engagement with said fingers.
Claim 8
Dependent Claim
111 words
A separable fastener the components of which are disposed on confrontable portions of a pair of relatively movable members at least one of which is provided with a component receiving opening, said separable fastener comprising: a. a latching sleeve component including a centrally disposed stud receiving sleeve having radial slits to form a set of radially expansible stud engaging fingers, a surrounding guard sleeve, and an opposed pair of laterally movable latching elements engageable with opposite margins of said opening to secure the latching sleeve component to the corresponding relatively movable member; b. and a stud component secured to the other relatively movable member in position for engagement with said fingers.
Claim 9
Dependent Claim
47 words
A separable fastener, as defined in claim 6, wherein: a. each of said relatively movable members is provided with a confrontable opening, and wherein; b. said stud component includes opposed laterally directed latching grooves for engaging opposed margins of the opening in said corresponding relatively movable member.
Claim 10
Dependent Claim
39 words
A separable fastener, as defined in claim 7, wherein: a. the latching sleeve component and stud components include mating portions whereby the latching sleeve component serves as a torquing means for turning the stud component into its secured position.
Claim 11
Dependent Claim
78 words
A separable fastener as defined in claim 6, wherein: a. said stud component includes a base portion dimensioned to cover an opening provided in the other relatively movable member, an opposing pair of latch elements projecting from the base portion for cooperation therewith to effect frictional engagement with opposing surfaces of the relatively movable member upon partial rotation of the base portion to provide a frictional engagement with the relatively movable member and retain the stud component thereon.
Claim 12
Dependent Claim
44 words
A separable fastener as defined in claim 6, wherein: a. the stud component includes a base portion and yieldable tab means extends laterally from the base portion for friction engagement with the corresponding relatively movable member to restrain separation of the stud component therefrom.
