Abstract
Abstract A portable two-part fastening device having a female section including a keyhole, a spring within the female section, and a ridge supported by the spring, an open channel in the female section contiguous with the narrow dimension of the keyhole, and means for mounting the female section to one part of the device. A male section comprises a button larger than the keyhole but having a width less than the open channel, with a flattened stud connecting said button to the other part of the two device. The button has an indentation on the outer face thereof of a geometrical configuration so as to mate with the ridge on the spring. The narrow dimension of the stud has a width less than the narrow dimension of the keyhole whereby the button and the stud may be positioned such that the button passes through the open slot and the stud passes through the narrow dimension of the keyhole with the spring exerting a biasing force against the face of the button hole so that the button and stud are maintained within the female portion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
234 words
A device for removably and pivotally fastening two devices together comprising a female section comprising: a C-shaped plate; a keyhole through the face of said C-shaped plate, said keyhold including an aperture and adjacent slot; an open channel in one leg of said C-shaped plate contiguous with said slot; spring means adjacent one leg of said C-shaped plate and biased toward the inner face of said C-shaped plate; a ridge secured to said spring means facing said keyhole; means for mounting said C-shaped plate and said spring means to one of said devices; a male section comprising: a button larger than said aperture but having a width less than said open channel; a flat stud connecting said button to the other one of said two devices, the narrow dimension of said stud having a width less than the width of said slot; an indentation in the outer face of said button having a geometrical configuration so as to mate with said ridge on said spring means; wherein said button and said stud may be positioned such that said button passes through said open channel and said stud passes through said slot with said spring means exerting a biasing force against the face of said button; said button and said stud being rotatable within said female section against the force of said spring means so as to engage and disengage said ridge and said indentation.
Claim 2
Independent Claim
