Coupler assembly for connecting corrugated sheet material

Claim 2

A coupler assembly adapted for interconnecting pieces of corrugated sheet material or the like to form point of purchase advertising displays, and characterized by the ability to permit the pieces to be interconnected in a selected rotational orientation, said coupler assembly comprising a female connecting member including a generally planar back wall, and a receiving portion mounted on one side of said back wall and comprising a generally U-shaped side wall extending outwardly from said back wall, and a front wall joined to said U-shaped side wall so as to be parallel to said front wall and said back wall which is bounded by said side wall and open at the top, said back wall including a back wall portion positioned so as to define the rear surface of said pocket, an opening positioned in said back wall portion within the area bounded by said receiving pocket, and a slot in said front wall which extends from said top of said pocket to a slot terminus at a medial location on said front wall, and a male connecting member comprising a pair of front and rear flanges, and a hub defining a central axis and extending between and interconnecting said flanges in an axially spaced apart and parallel relationship which is transverse to said central axis, with the axial separation being at least about the thickness of said front wall, and with said rear flange being dimensioned to rotatably fit within said pocket and with said hub dimensioned to rotatably fit within said slot, an extension on the side of said rear flange opposite said front flange and aligned along said central axis and sized and positioned so that said extension is received into said opening positioned on said back wall portion when said members are in an assembled position, and a flat planar tab joined to the side of said front flange opposite said hub and extending parallel to said central axis, whereby said male connecting member can be releasably coupled to said female connecting member with said male connecting member in substantially any rotational orientation about said central axis by sliding said rear flange laterally into said pocket to an assembled position wherein said rear flange is substantially completely received in said pocket, said front flange overlies the side of said front wall opposite said pocket, and said hub is received in said slot adjacent said slot terminus.

Claim 3

The coupler assembly as defined in claim 1 wherein said male and female connecting members include interengaging means for resisting rotation of said male connecting member about said central axis when said members are in said assembled position.

Claim 4

The coupler assembly as defined in claim 2 wherein said U-shaped side wall includes a generally semicircular inner surface facing the interior of said pocket, and wherein said rear flange has a generally circular outline of a diameter somewhat less than the diameter of said semi-circular inner surface.

Claim 5

The coupler assembly as defined in claim 3 wherein said interengaging means comprises a plurality of sawtooth like projections spaced along the circumferential periphery of said rear flange, and at least one protuberance on said inner surface of said side wall for engaging between selected projections when said members are in said assembled position.

Claim 6

The coupler assembly as defined in claim 1 wherein said back wall portion includes an inclined cam surface extending in alignment with said slot and from the top of said pocket to said opening in said back wall, for camming said extension into said opening during movement of said rear flange toward said assembled position.

Claim 7

A coupler assembly adapted for interconnecting pieces of corrugated sheet material or the like to form point of purchase advertising displays, and characterized by the ability to permit the pieces to be interconnected in a selected rotational orientation, said coupler assembly comprising a female connecting member including a generally planar back wall, and a receiving portion mounted on one side of said back wall and comprising a generally U-shaped side wall extending outwardly from said back wall, and a front wall joined to said U-shaped side wall so as to be parallel to said front wall and said back wall which is bounded by said side wall and open at the top, and a slot in said front wall which extends from said top of said pocket to a slot terminus at a medial location on said front wall, and a male connecting member comprising a pair of front and rear flanges of generally circular outline, and a hub defining a central axis and extending between and interconnecting said flanges in an axially spaced apart and parallel relationship which is transverse to said central axis, with said front and rear flanges being aligned along said central axis, and with the axial separation of said flanges being at least about the thickness of said front wall, and with said rear flange being dimensioned to rotatably fit within said pocket and with said hub dimensioned to rotatably fit within said slot, said front flange having a diameter substantially the same as the diameter of said rear flange, and a flat planar tab joined to the side of said front flange opposite said hub and extending parallel to said central axis and extending along said central axis, said tab having a width substantially the same as the diameter of said front flange, said tab being of generally rectangular outline and defining a free end edge remote from said front flange, and wherein said tab includes at least one longitudinally extending inclined projection, and with the inclined projection being inclined so as to increase in thickness in the direction leading from the free end edge to the front flange, whereby said male connecting member can be releasably coupled to said female connecting member with said male connecting member in substantially any rotational orientation about said central axis by sliding said rear flange laterally into said pocket to an assembled position wherein said rear flange is substantially completely received in said pocket, said front flange overlies the side of said front wall opposite said pocket, and said hub is received in said slot adjacent said slot terminus.

Claim 8

A coupler assembly adapted for interconnecting pieces of corrugated sheet material or the like to form point of purchase advertising displays, and characterized by the ability to permit the pieces to be interconnected in a selected rotational orientation, said coupler assembly comprising a female connecting member including a generally planar back wall, and a receiving portion mounted on one side of said back wall and comprising a generally U-shaped side wall extending outwardly from said back wall, and a front wall joined to said U-shaped side wall so as to be parallel to said front wall and said back wall which is bounded by said side wall and open at the top, and a slot in said front wall which extends from said top of said pocket to a slot terminus at a medial location on said front wall, and a male connecting member comprising a pair of front and rear flanges of generally circular outline, and a hub defining a central axis and extending between and interconnecting said flanges in an axially spaced apart and parallel relationship which is transverse to said central axis, with said front and rear flanges being aligned along said central axis, and with the axial separation of said flanges being at least about the thickness of said front wall, and with said rear flange being dimensioned to rotatably fit within said pocket and with said hub dimensioned to rotatably fit within said slot, said front flange having a diameter substantially the same as the diameter of said rear flange, and a flat planar tab joined to the side of said front flange opposite said hub and extending parallel to said central axis and extending along said central axis, said tab having a width substantially the same as the diameter of said front flange, said tab being of generally rectangular outline and defining a free end edge remote from said front flange, and wherein said tab includes at least one longitudinally extending inclined projection, and with the inclined projection being inclined so as to increase in thickness in the direction leading from the free end edge to the front flange, whereby said male connecting member can be releasably coupled to said female connecting member with said male connecting member in substantially any rotational orientation about said central axis by sliding said rear flange laterally into said pocket to an assembled position wherein said rear flange is substantially completely received in said pocket, said front flange overlies the side of said front wall opposite said pocket, and said hub is received in said slot adjacent said slot terminus.
