Abstract
Abstract A separable fastener is disclosed especially for use with pieces of furniture adapted to be separated and reassembled in one or more relationships. The device includes sockets provided in 2 parts to be joined, one socket having a helical thread and the other socket having a recess adapted respectively to cooperate with the helical thread and a spring pressed detent carried by a pin adapted to be inserted into and withdrawn from the sockets.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A separable fastener adapted to separably interconnect a pair of elements, comprising a pair of cylindrical sockets, secured in bores in said elements, at least one of said sockets being extended through the element in which it is secured and having a helical thread in its inside surface, the other socket having a recess in its inside surface, and a pin insertable into and removable from said sockets when the sockets are aligned, one end of the pin having a helical thread adapted to mate with the helical thread in said one socket, and the other end of the pin having a yielding detent engageable and disengageable with the recess in said other socket.
Claim 2
Dependent Claim
114 words
A separable fastener adapted to separably interconnect a pair of elements, comprising a pair of cylindrical sockets, secured in bores in said elements, at least one of said sockets being extended through the element in which it is secured and having a helical thread in its inside surface, the other socket having a recess in its inside surface, and a pin insertable into and removable from said sockets when the sockets are aligned, one end of the pin having a helical thread adapted to mate with the helical thread in said one socket, and the other end of the pin having a yielding detent engageable and disengageable with the recess in said other socket.
Claim 3
Dependent Claim
61 words
A fastener as defined in claim 1 in which the pin is proportioned so that an end thereof is substantially flush with the external surface of one of the elements when the pin is inserted in the sockets, and the pin further having a slotted end adapted to cooperate with a tool for turning the pin and thereby removing the pin.
Claim 4
Dependent Claim
44 words
A fastener as defined in claim 1 in which the recessed socket further has a tapered helical groove extended from the recess therein to facilitate separation of the detent when the threaded part of the pin is turned and withdrawn from the threaded socket.
Claim 5
Dependent Claim
38 words
A fastener as defined in claim 1 which the pin has an internal cavity in which the detent is mounted, and a spring accomodated in said cavity and acting on the detent to yieldingly urge the detent outwardly.
Claim 6
Dependent Claim
129 words
A separable fastener adapted to separably interconnect a pair of elements, comprising a pair of cylindrical sockets secured in bores in said elements, at least one of said sockets being extended through the element in which it is secured and having a helical thread in its inside surface, the other socket having a recess in its inside surface, a unitary pin having end portions one of which is threaded and the other of which carries a yielding detent, the thread of the pin and said detent being positioned to cooperate respectively with the threaded and recessed sockets, and half-pin elements one of which is threaded and the other of which is provided with a yielding detent, the half-pin elements being insertable in the sockets alternatively to said unitary pin.
Claim 7
Dependent Claim
129 words
A separable fastener adapted to separably interconnect a pair of elements, comprising a pair of cylindrical sockets secured in bores in said elements, at least one of said sockets being extended through the element in which it is secured and having a helical thread in its inside surface, the other socket having a recess in its inside surface, a unitary pin having end portions one of which is threaded and the other of which carries a yielding detent, the thread of the pin and said detent being positioned to cooperate respectively with the threaded and recessed sockets, and half-pin elements one of which is threaded and the other of which is provided with a yielding detent, the half-pin elements being insertable in the sockets alternatively to said unitary pin.
