1. Apparatus for detachably interconnecting two objects including, in combination:
- a female member adapted to be secured to one of the objects and defining a receptacle and an entrance leading into said receptacle, a male member adapted to be secured to the other object and including a shank with an axis and an enlarged head on said shank adapted for movement into and out of said receptacle through said entrance and rotatable about said axis while in said receptacle, pawl means movable between a locking position projecting into said entrance for interference with passage of said head therethrough and a release position disposed out of said entrance, said head being non-symmetrical with respect to said axis so that while passing through said entrance in one rotational orientation thereof said head will clear said pawl means in its locking position and in all other rotational orientations it will engage said pawl means in its locking position, and bias means resiliently urging said pawl means to its locking position and yieldably accommodating movement of said pawl means to its release position, whereby said pawl means is yieldably movable by said head to permit passage thereof into said receptacle and is non-yieldably engageable by said head to prevent removal thereof from said receptacle in all but said one rotational orientation.

Abstract
A quick-release connecting apparatus for detachably interconnecting two objects includes male and female members, respectively attachable to the objects. The female member has a generally U-shaped receptacle formed therein which opens at a peripheral edge thereof, and an aperture formed in the front surface of the female member which is aligned with but smaller than the receptacle and communicates therewith. The male member has a stud projection therefrom with a part-circular head at its distal end which is too large to pass through the aperture but is dimensioned to be received in the receptacle from its open end with the stud disposed through the aperture and is rotatable about the axis of the stud while disposed in the receptacle. A spring-biased pawl is mounted on the female member for movement between a locking position projecting into the entrance of the receptacle and a release position out of the entrance. The button moves the pawl out of the way upon insertion into the receptacle to permit insertion in any orientation, but the pawl prevents removal of the head from the receptacle except when it is in a single orientation wherein the straight side faces the pawl. Both reciprocating and pivoting pawls are disclosed.

12. Apparatus for detachably interconnecting two objects including, in combination:
- a female member adapted to be secured to one of the objects and having a front surface and an aperture in said front surface which extends to a peripheral edge thereof and has an open end thereat, said female member having a receptacle formed therein behind said front surface, said receptacle being larger than said aperture and communicating with the entire area of said aperture and having an entrance which opens at a peripheral edge of said female member adjacent to the open end of said aperture, a male member adapted to be secured to the other object and having a shank projecting therefrom and a head at the distal end of said shank, said head being dimensioned to prevent passage thereof through said aperture in directions normal to said front surface but to accommodate movement to and from said receptacle in directions parallel to said front surface from said peripheral edge thereof with said shank extending through said opening and further to accommodate rotation of said head about the axis of said shank while in said receptacle, pawl means, means mounting said pawl means on said female member for reciprocating movement between a locking position projecting into said entrance for interference with passage of said head therethrough in directions parallel to said front surface and a release position disposed out of said entrance, said head being non-symmetrical with respect to said axis so that while passing through said entrance in one rotational orientation thereof said head will clear said pawl means in its locking position and in all other rotational orientations it will engage said pawl means in its locking position, and bias means resiliently urging said pawl means to its locking position and yieldably accommodating movement of said pawl means to its release position, whereby said pawl means is yieldably deflectable by said head to permit passage thereof into said receptacle in directions parallel to said front surface and is non-yieldably engageable by said head to prevent removal thereof from said receptacle in all but said one rotational orientation.

19. Apparatus for detachably interconnecting two objects including, in combination:
- a female member adapted to be secured to one of the objects and defining a receptacle and an entrance leading into the receptacle, a male member adapted to be secured to the other object and including a shank with an axis and an enlarged head on said shank adapted for movement into and out of said receptacle through said entrance and rotatable about said axis while in said receptacle, retaining means resiliently biased to a locking position projecting into said entrance for interference with passage of said head therethrough, said retaining means being yieldably movable to a release position accommodating passage of said head through said entrance, said head being non-symmetrical with respect to said axis so that while passing through said entrance in one rotational orientation thereof said head will clear said retaining means in its locking position and in all other rotational orientations it will engage said retaining means in its locking position, said retaining means being yieldably movable to its release position in response to engagement by said head during passage thereof into said receptacle and being non-yieldably engageable by said head in said receptacle to prevent removal thereof from said receptacle in all but said one rotational orientation.
