Abstract
Abstract A fitting for releasably connecting two parts, especially furniture parts, with each other in which a socket provided with an inner screw thread is fixed in a bore of one part and in which a shaft is turnably but axially immovably mounted in a shell fixed in a bore in the other part axially aligned with the bore in the one part. The shaft has a portion projecting axially beyond the shell and provided with an outer screw thread for threading engagement with an inner screw thread of the socket. An actuating member in form of a lever is fixed to the shaft and projects radially therefrom adjacent the open end of the shell for turning the shaft and the threaded portion projecting therefrom for threadingly engaging the thread on the projecting portion with that of the socket.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
110 words
A fitting for releasably connecting two parts, especially furniture parts, comprising, in combination, a socket fixed in a bore of one of said parts; a shell axially aligned with and facing with one end thereof a corresponding end of said socket and fixed in a bore of the other of said parts; a member turnably but axially immovably mounted in said shell and having an axially projecting threaded portion connectable with said socket; and an actuating member fixed to said turnable member located between the facing ends of said shell and said socket for turning said turnable member so as to connect that projecting threaded portion thereof to said socket.
Claim 2
Dependent Claim
110 words
A fitting for releasably connecting two parts, especially furniture parts, comprising, in combination, a socket fixed in a bore of one of said parts; a shell axially aligned with and facing with one end thereof a corresponding end of said socket and fixed in a bore of the other of said parts; a member turnably but axially immovably mounted in said shell and having an axially projecting threaded portion connectable with said socket; and an actuating member fixed to said turnable member located between the facing ends of said shell and said socket for turning said turnable member so as to connect that projecting threaded portion thereof to said socket.
Claim 3
Dependent Claim
