Abstract
Abstract The invention is a mechanical device which enables the connection of two ferably longitudinal rigid members. Utilization of the invention enables the quick connection and disconnection of members manually without the aid of tools. The device is designed such that the connection is positively locked. The connection is also characterized in that torques and bending moments will not be transmitted between the two connected members through the device. The device, however, will transmit tensile, compressive, and shear loads.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
256 words
Means for detachably connecting together a first member and a second member, comprising: a shaft; means for securing one end of said shaft to said first member; said shaft being formed with a generally spherical head at its end remote from said first member; said second member being formed with a generally semi-spherical recess in one face thereof for receiving therein the generally spherical shaft head; and with at least one redially projecting retainer rod; a slide member that is mounted for sliding movement on said shaft intermediate said first member and said shaft head, said slide member being formed with at least one pin that projects axially of said shaft from said slide member and toward said second member; a sleeve adapted to seat about the end of said second member, said sleeve being generally cup-shaped and formed with a web portion and with an annular wall, said web being formed with an aperture to receive said shaft therethrough but to prevent passage of said shaft head therethrough, the annular wall of said sleeve being formed with at lease one axially-extending opening for the receptin of said pin or pins therein and with at least one generally L-shaped slot for receiving therein said retainer rod on said second member upon assembly of said sleeve about the end of said second member and manipulation of said sleeve to seat said retainer rod in said slot; and urging means disposed to constantly urge said slide member in its assembled position toward the end of said second member.
Claim 2
Dependent Claim
256 words
Means for detachably connecting together a first member and a second member, comprising: a shaft; means for securing one end of said shaft to said first member; said shaft being formed with a generally spherical head at its end remote from said first member; said second member being formed with a generally semi-spherical recess in one face thereof for receiving therein the generally spherical shaft head; and with at least one redially projecting retainer rod; a slide member that is mounted for sliding movement on said shaft intermediate said first member and said shaft head, said slide member being formed with at least one pin that projects axially of said shaft from said slide member and toward said second member; a sleeve adapted to seat about the end of said second member, said sleeve being generally cup-shaped and formed with a web portion and with an annular wall, said web being formed with an aperture to receive said shaft therethrough but to prevent passage of said shaft head therethrough, the annular wall of said sleeve being formed with at lease one axially-extending opening for the receptin of said pin or pins therein and with at least one generally L-shaped slot for receiving therein said retainer rod on said second member upon assembly of said sleeve about the end of said second member and manipulation of said sleeve to seat said retainer rod in said slot; and urging means disposed to constantly urge said slide member in its assembled position toward the end of said second member.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 wherein the first and second members, shaft and sleeve are of generally cylindrical cross section.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1 wherein the urging means is a compression spring disposed about said shaft and between said first member and said slide.
Claim 5
Dependent Claim

The apparatus of claim 3 further comprising a washer disposed about said shaft and between said spring and said slide.
Claim 6
Dependent Claim
23 words
The apparatus of claim 1 wherein the slide has at least one tab fixedly attached thereto to facilitate manual manipulation of said slide.
Claim 7
Dependent Claim
21 words
The apparatus of claim 1 wherein the means for securing said shaft to said first member is a threaded securing means.
Claim 8
Dependent Claim
74 words
The apparatus of claim 1 wherein the urging means is disposed to constantly urge said slide member in a position such that the slide member pin or pins are inserted within the axially extending opening or openings of the sleeve and the retainer rod of the second member is thus positively enclosed and locked within the generally L-shaped slot or slots of the sleeve upon assembly of said first member and said second member.
