Abstract
Abstract Extruded bars or columns of a set of structural members are each formed with a central passage and with at least one longitudinal groove having a restricted orifice. A connector member has a body portion secured in the passage of one member and two catches mounted on the body portion and projecting into the groove of another member. One catch has a leading, enlarged head portion and a reduced neck portion trailing the head portion. An operating device on the body portion includes a single, manually operable drive shaft and two motion transmitting eccentrics respectively connecting the shaft to the two catches for moving the catches inward and outward of the groove orifice in timed sequence so that the neck portion of the one catch together with the other catch laterally secures the catches in the orifice while the enlarged head prevents accidental withdrawal of the catches from their locking position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
176 words
In an assembly including a first structural member formed with an opening; a second structural member formed with a groove having a restricted orifice, said groove and said orifice being elongated; and a connector element having a body portion secured in said opening, catch means mounted on said body portion, and operating means on said body portion for moving said catch means through said orifice into and out of locking engagement with said second member, the improvement which comprises: (a) said catch means including two catch members, (1) one of said catch members having an enlarged head portion leading during movement of said one catch member inward of said groove, and a reduced neck portion adjacent said head portion in trailing relationship; and (b) said operating means including (1) a single, manually operable drive member, and (2) motion transmitting means connecting said drive member to said two catch members for moving the catch members inward and outward of said groove in timed sequence, (3) said one catch member leading the other catch member during said moving.
Claim 2
Dependent Claim
176 words
In an assembly including a first structural member formed with an opening; a second structural member formed with a groove having a restricted orifice, said groove and said orifice being elongated; and a connector element having a body portion secured in said opening, catch means mounted on said body portion, and operating means on said body portion for moving said catch means through said orifice into and out of locking engagement with said second member, the improvement which comprises: (a) said catch means including two catch members, (1) one of said catch members having an enlarged head portion leading during movement of said one catch member inward of said groove, and a reduced neck portion adjacent said head portion in trailing relationship; and (b) said operating means including (1) a single, manually operable drive member, and (2) motion transmitting means connecting said drive member to said two catch members for moving the catch members inward and outward of said groove in timed sequence, (3) said one catch member leading the other catch member during said moving.
Claim 3
Dependent Claim
59 words
In an assembly as set forth in claim 1, said drive member being mounted on said body portion for rotation about an axis, and said motion transmitting means including two eccentrics mounted on said drive member and engaging said catch members for moving the catch members in said timed sequence in response to said rotation of the drive member.
Claim 4
Dependent Claim
51 words
In an assembly as set forth in claim 1, said catch members being juxtaposed in a direction transverse to the direction of said inward movement, the combined width of said neck portion and of the other catch member in said transverse direction being substantially equal to the width of said orifice.
Claim 5
Dependent Claim
37 words
In an assembly as set forth in claim 3, said second structural member being formed with an elongated recess in said groove opposite said orifice, the width of said recess being substantially equal to said combined width.
Claim 6
Dependent Claim
62 words
In an assembly as set forth in claim 1, said body portion being of U-shaped section in a plane parallel to the direction of said movement and having two leg portions connected by a bight portion, said catch members being mounted between said leg portions, said drive member being a shaft journaled in said leg portions for angular movement about an axis.
Claim 7
Dependent Claim
33 words
In an assembly as set forth in claim 5, said catch members being formed with respective openings, and said shaft passing through said openings and carrying said motion transmitting means in said openings.
Claim 8
Dependent Claim
30 words
In an assembly as set forth in claim 6, said leg portions having respective end faces remote from said bight portion and rounded in circular arcs centered in said axis.
Claim 9
Dependent Claim
41 words
In an assembly as set forth in claim 7, said first member being formed with a recess in said opening, the width of said recess being equal to the combined width of said head portion and of the other catch member.
Claim 10
Dependent Claim
