Abstract
Abstract A safety back for an appliance cabinet (such as a TV cabinet) cannot be opened without following a procedure involving several steps in predetermined sequence and, in some cases, without having a special tool. The object is to provide a cabinet back which cannot be removed by small children or incompetent persons who might be injured by electrical shock if they put their hands inside the cabinet.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
71 words
A fastener system for a cabinet back panel comprising means for resiliently pressing said back panel against said cabinet to preclude ambient rattling of said panel against said cabinet responsive to ambient vibrations, said back panel having means for precluding release of said panel from said cabinet unless said panel is first slipped to a release position, and mechanical interlock means for preventing slippage of said panel relative to said cabinet.
Claim 2
Dependent Claim
71 words
A fastener system for a cabinet back panel comprising means for resiliently pressing said back panel against said cabinet to preclude ambient rattling of said panel against said cabinet responsive to ambient vibrations, said back panel having means for precluding release of said panel from said cabinet unless said panel is first slipped to a release position, and mechanical interlock means for preventing slippage of said panel relative to said cabinet.
Claim 3
Dependent Claim
37 words
The system of claim 1 and means for selectively capturing or releasing said panel on said cabinet, said capture means being inoperative to release said panel unless said panel has been previously slipped to said release position.
Claim 4
Dependent Claim
16 words
The system of claim 2 wherein said mechanical interlock includes a socket on a power cord.
Claim 5
Independent Claim
103 words
A system for removably but lockingly attaching a panel to a base member, said system comprising: a plurality of key hole slots disposed on said panel, one edge of said slots having a cove notch capture slot formed therein, fasteners fitting through said cove in at least some of said key hole slots and attached to said base member, said fasteners shaped to release said panel when said panel is moved with respect to said base member so as to remove said fasteners from said cove, and mechanical interlock means to prevent the movement of said panel with respect to said base member,
Claim 6
Independent Claim
103 words
A system for removably but lockingly attaching a panel to a base member, said system comprising: a plurality of key hole slots disposed on said panel, one edge of said slots having a cove notch capture slot formed therein, fasteners fitting through said cove in at least some of said key hole slots and attached to said base member, said fasteners shaped to release said panel when said panel is moved with respect to said base member so as to remove said fasteners from said cove, and mechanical interlock means to prevent the movement of said panel with respect to said base member,
Claim 7
Dependent Claim
44 words
The system of claim 4 wherein said key hole slots and said fasteners have mating shapes which are substantially similar, said key hole slots having a large central opening and oppositely disposed wing openings, and said cove being formed assymmetrically in said central opening.
Claim 8
Dependent Claim
80 words
The system of claim 4 wherein said fastener has a generally ''''top hat'''' shape, the crown of said ''''top hat'''' shape being attached to the base member, the brim of said ''''top hat'''' shape disposed away from the base member a distance approximately equal to the thickness of said panel, said slot comprising a large central opening which enables the brim of said ''''top hat'''' shape to pass therethrough, and said cove being a communicating area which receives said crown.
Claim 9
Dependent Claim
45 words
The system of claim 6 wherein said ''''top hat'''' shape comprises a first part formed along an edge of said brim to guide said panel into a capture position, and a second part formed on said brim to press said panel into a captured position.
Claim 10
Dependent Claim
12 words
The system of claim 7 wherein said brim is a Bellville Spring.
Claim 11
Dependent Claim
68 words
The system of claim 4 wherein said fastener comprises an integral wing headed fastener having one part which rotatably fits within said keyhole slot and a second part which rotates between either a release position aligned with said keyhole or a capture position extending over the panel, said second part being misaligned when said fastener is in said release position and when said cove receives said one part.
Claim 12
Dependent Claim
21 words
The system of claim 9 wherein said panel is a cabinet back panel and said base member is a television cabinet.
Claim 13
Dependent Claim
17 words
The system of claim 10 wherein said mechanical interlock comprises a power cord for a television set.
Claim 14
Dependent Claim
74 words
The system of claim 4 wherein said fastener is an integral member having a head, opposed resilient wings and interconnecting body member, said head having dimensions which can only be turned by a tool, said keyhole slot having dimensions which allow said fastener wings to pass through but not to escape therefrom, and said base member having a mating keyhole slot which allows said fastener wings to both pass therethrough and to escape therefrom.
Claim 15
Dependent Claim
25 words
The system of claim 4 wherein said fasteners are made from a resilient material which is deformed to press said panel against said base member.
