Abstract
Abstract A connector wherein a shaft member has projection means such as lip for engaging a forwardly facing edge of a strip to prevent rearward movement of the shaft member relative to the strip. Actuating means are provided for moving the strip from a normally closed position of engagement with the projection means to an open position of disengagement.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
In a connector, the combination of: a first member comprising two flat elongated spring plate legs attached together at a junction, and having an edge facing in a forward direction with the portion between said junction and the ends of said legs spaced apart and with said ends inclined toward each other; a single button contacting said junction of said two legs for longitudinally compressing said first member to bow said portion between said junction and the ends of said legs outwardly in opposite directions substantially normal to said forward direction from a normally closed position to an open position; a second member having a shaft which fits between said legs in a position transverse to the direction of said longitudinal compression with rearwardly facing lip means engageable with said forwardly facing edge when said legs are in said closed position for positively latching and preventing rearward movement of said second member relative to said first member; and a mounting member holding said first member, including an opening for receiving said shaft and wall means for abutting said ends of said legs when said legs are longitudinally compressed by said button.
Claim 2
Dependent Claim
191 words
In a connector, the combination of: a first member comprising two flat elongated spring plate legs attached together at a junction, and having an edge facing in a forward direction with the portion between said junction and the ends of said legs spaced apart and with said ends inclined toward each other; a single button contacting said junction of said two legs for longitudinally compressing said first member to bow said portion between said junction and the ends of said legs outwardly in opposite directions substantially normal to said forward direction from a normally closed position to an open position; a second member having a shaft which fits between said legs in a position transverse to the direction of said longitudinal compression with rearwardly facing lip means engageable with said forwardly facing edge when said legs are in said closed position for positively latching and preventing rearward movement of said second member relative to said first member; and a mounting member holding said first member, including an opening for receiving said shaft and wall means for abutting said ends of said legs when said legs are longitudinally compressed by said button.
Claim 3
Dependent Claim
93 words
The combination of claim 1 wherein said mounting member includes a flat casing having top and bottom face members joined at an outer periphery with said first member mounted inside said casing to bow outwardly toward said face members in a direction substantially normal to the plane of the casing between a normally closed position and an open position; and including longitudinal wall means in said casing defining a passage extending in the direction of the plane of said casing between the periphery of said casing and said legs for receiving said shaft.
Claim 4
Dependent Claim
58 words
The combination of claim 1 wherein said first member includes a unitary flat flexible strip bent back on itself to form two opposing legs unconnected at one end and capable of bowing outwardly in directions substantially opposite to each other from said normally closed position to said open position when said bent strip is subjected to longitudinal compression.
Claim 5
Dependent Claim
31 words
The combination of claim 1 wherein said shaft constitutes a solid member having a forwardly tapered front end for moving said legs from said normally closed position to said open position.
Claim 6
Dependent Claim
50 words
The combination of claim 2 wherein said button for moving said legs from said normally closed position to said open position comprises a depressible portion of the periphery of said casing displaced approximately 90* from the opening in the periphery defined by said longitudinal wall means for receiving said shaft.
Claim 7
Dependent Claim
73 words
The combination of claim 2 wherein said first member comprises: a U-shaped unitary latching strip having substantially straight opposing legs joined together at a junction and spaced apart a maximum distance at said junction and a minimum distance at their ends to buckle outwardly when subjected to longitudinal compression by said button; and including a chain connecting the rearward end of said shaft with said casing for removably securing keys and the like.
