Abstract
Abstract The invention relates to a device for coupling or plugging square tubes, which comprises a hollow base member having a hollow coupling member projecting therefrom and, if desired, one or more other coupling members projecting from the base member. The other coupling members have axial partitions in the mid-portions thereof, at least the mid-portion of which is thick enough to receive a sheet metal screw and, if desired, there is provided a plug for the hollow coupling member for receiving a sheet metal screw.

170 words
A tube assembling device for square tubes which comprises: a hollow base member; a first square-shaped hollow coupling member projecting from and integral with said base member and having side walls substantially coincident with the walls of said base member, the hollow of said base member and the hollow of said first coupling member comprising a common bore which is open only at the free end of said first coupling member; a second coupling member comprising parallel side walls integral with and projecting from said base member to and integral with an end wall; and a transverse partition parallel with said end wall and integral with and connecting the mid-portions of said side walls; the side and end walls of said second coupling member and said transverse partition extending to and terminating in parallel planes which are normal to said base member, and said partition having a thickness, at least in the transverse or axial mid-portion thereof, which is substantially greater than the thickness of said side and end walls.
Claim 2
Dependent Claim
170 words
A tube assembling device for square tubes which comprises: a hollow base member; a first square-shaped hollow coupling member projecting from and integral with said base member and having side walls substantially coincident with the walls of said base member, the hollow of said base member and the hollow of said first coupling member comprising a common bore which is open only at the free end of said first coupling member; a second coupling member comprising parallel side walls integral with and projecting from said base member to and integral with an end wall; and a transverse partition parallel with said end wall and integral with and connecting the mid-portions of said side walls; the side and end walls of said second coupling member and said transverse partition extending to and terminating in parallel planes which are normal to said base member, and said partition having a thickness, at least in the transverse or axial mid-portion thereof, which is substantially greater than the thickness of said side and end walls.
Claim 3
Dependent Claim
39 words
A tube assembling device of claim 1, in which the portions of said transverse partition adjacent said side walls are thinner than the axial mid-portion and have substantially the same order of thickness as said side and end walls.
Claim 4
Dependent Claim
34 words
A tube assembling device of claim 1, in which said transverse partition has a thickness, both in the transverse and axial mid-portions thereof substantially greater than the thickness of said side and end wall.
Claim 5
Dependent Claim
34 words
A tube assembling device of claim 2, in which said transverse partition has a thickness, both in the transverse and axial mid-portions thereof substantially greater than the thickness of said side and end wall.
Claim 6
Dependent Claim
28 words
A tube assembling device of claim 4, in which a mid-portion of said transverse partition is integrally-connected to said base member and said end wall by longitudinal partitions.
Claim 7
Dependent Claim
28 words
A tube assembling device of claim 5, in which said longitudinal partitions are parallel to said planes and are also integrally-connected with the mid-portions of said side walls.
Claim 8
Dependent Claim
30 words
A tube assembling device of claim 6, in which said longitudinal partitions have a thickness which is substantially in the same order of thickness as said side and end walls.
Claim 9
Dependent Claim
98 words
A tube assembling device of claim 1, in which said base member is cube-shaped and in which each said coupling member projects from a face of said base member with the sides parallel to the edges thereof and spaced therefrom a distance equal to the thickness of the tubes to be coupled thereby, whereby, when a coupling member is inserted into a tube, any side face of said base member which does not have a coupling member projecting therefrom, will lie in a common plane with a side of a tube when it is fitted on said coupling.
Claim 10
Dependent Claim
73 words
A tube assembling device of claim 8, which further comprises a hollow plug which is adapted to fit snugly into the bore of said first coupling member which is shorter than the depth of said bore, and stop means to limit the distance that said plug can be inserted into said bore such that, when said plug is inserted, it fills a substantial portion of said bore inward from the free end thereof.
Claim 11
Dependent Claim
52 words
A tube assembling device of claim 1, in which said plug is inserted in said first coupling member and a tube is fitted thereon and secured thereto by a fastener passing through a wall of said tube and the juxtaposed wall of said coupling member and into and anchored in said plug.
Claim 12
Dependent Claim
40 words
A tube assembling device of claim 1, in which a tube is fitted onto said second coupling member and fastened thereto by a fastener which extends through a wall of said tube and into a mid-portion of said transverse partition.
Claim 13
Dependent Claim
69 words
A tube assembling device of claim 1, in which a tube is fitted on said second coupling member with opposite tube walls thereof juxtaposed to and in contact with the ends of the axial mid-portion of said transverse partition and at least one said tube wall is fastened to said second coupling member by a fastener extending through said tube wall into a juxtaposed end of said axial mid-portion.
Claim 14
Dependent Claim
142 words
A tube assembling device for square tubes which comprises: a hollow base member; a square-shaped, hollow coupling member projecting from and integral with said base member and having side walls substantially coincident with the walls of said base member, the hollow of said base member and the hollow of said coupling member comprising a common bore which is open only at the free end of said coupling member and extends to the bottom wall of said base member; and a plug which is adapted to fit snugly into the bore of said first coupling member and which is shorter than the depth of said bore, and stop means to limit the distance that said plug can be inserted into said bore such that, when said plug is inserted, it fills a substantial portion of said bore inward from the free end thereof.
Claim 15
Dependent Claim
142 words
A tube assembling device for square tubes which comprises: a hollow base member; a square-shaped, hollow coupling member projecting from and integral with said base member and having side walls substantially coincident with the walls of said base member, the hollow of said base member and the hollow of said coupling member comprising a common bore which is open only at the free end of said coupling member and extends to the bottom wall of said base member; and a plug which is adapted to fit snugly into the bore of said first coupling member and which is shorter than the depth of said bore, and stop means to limit the distance that said plug can be inserted into said bore such that, when said plug is inserted, it fills a substantial portion of said bore inward from the free end thereof.
Claim 16
Dependent Claim
48 words
A tube plugging device of claim 13, in which said plug is inserted in said first coupling member and a tube is fitted thereon and secured thereto by a fastener extending through a wall of said tube and the juxtaposed wall of said coupling member into said plug.
Claim 17
Dependent Claim
16 words
A tube assembling device of claim 1, in which said bore tapers to said base wall.
Claim 18
Dependent Claim
16 words

Claim 19
Dependent Claim
16 words
A tube assembling device of claim 13, in which said bore tapers to said base wall.
Claim 20
Dependent Claim
16 words
A tube assembling device of claim 14, in which said bore tapers to said base wall.
