Abstract
Abstract A stackable hinging printed circuit board support is provided, comprising an integral plastic molding. The support is provided with an intermediate notch and an adjacent wall section which is sufficiently thin as to permit flexing for pivoting of one printed circuit board away from another. The support has an upstanding circular segment pilot for fitting in a circular aperture of an overlying printed circuit board. The support has at its bottom a W prong structure dimensioned for insertion in a circular aperture of a printed circuit board so as to coact with the upstanding circular segment pilot of an underlying support to wedge the pilot in the aperture. The W prong of one support is received in a recess provided in the body of a subjacent support.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
151 words
A one-piece integral panel support of resinous plastic material comprising an upper body and a lower body, said lower body being spaced beneath said upper body and interconnected to said upper body by a thin flexible section providing for shock resistance and forming a hinge for pivoting, means for resiliently fastening said lower body within an opening in a panel and extending below said lower body, said upper body having an upper facing recess, a resilient panel latching arm supported by said upper body above said upper facing recess for holding the edge of a panel, a circular segment pilot upstanding from the upper surface of said upper body adjacent said panel latching arm, and said resiliently fastening means having a slightly smaller transverse dimension than the corresponding transverse dimension of said upper facing recess and having a wedging means for providing a holding force within an opening in a panel.
Claim 2
Dependent Claim
151 words
A one-piece integral panel support of resinous plastic material comprising an upper body and a lower body, said lower body being spaced beneath said upper body and interconnected to said upper body by a thin flexible section providing for shock resistance and forming a hinge for pivoting, means for resiliently fastening said lower body within an opening in a panel and extending below said lower body, said upper body having an upper facing recess, a resilient panel latching arm supported by said upper body above said upper facing recess for holding the edge of a panel, a circular segment pilot upstanding from the upper surface of said upper body adjacent said panel latching arm, and said resiliently fastening means having a slightly smaller transverse dimension than the corresponding transverse dimension of said upper facing recess and having a wedging means for providing a holding force within an opening in a panel.
Claim 3
Dependent Claim
37 words
A one-piece integral panel support as defined in claim 1, wherein said resiliently fastening means includes a W-shaped resilient prong and a downwardly extending stem portion integrally formed with the center member of said W-shaped resilient prong.
Claim 4
Dependent Claim
32 words
A one-piece integral panel support as defined in claim 2, wherein said wedging means comprises a lateral surface on said stem portion that tapers outwardly in the direction toward said lower body.
