Claim 1
Independent Claim
296 words
A portable support bar assembly for mounting about a doorway comprising a first elongated member having a first end and a second end; a first substantially V-shaped member having an upper leg joined to a lower leg, said V-member being engaged at a vertex formed by said upper and lower legs to the first horizontal elongated member adjacent said first end thereof, the first V-shaped member having a first stub projecting from said lower leg, said first stub being parallel to the first horizontal elongated member and beyond the terminus of said first end; a second substantially V-shaped member having an upper leg joined to a lower leg, said V-shaped member being engaged at a vertex formed by said upper and lower legs to the first horizontal elongated member adjacent said second end thereof, the second V-shaped member having a second stub projecting from said lower leg, said second stub being parallel to the first horizontal member and beyond the terminus of said second end; a second horizontal elongated member having a first end and a second end and engaged about its said first end to the upper leg of the first V-shaped member and about its said second end to the upper leg of the second V-shaped member; a first cross strut engaged about said first end of the second horizontal elongated member and about said lower leg of said first V-shaped member; a second cross strut engaged about said second end of the second horizontal elongated member and about said lower leg of said second V-shaped member; a first and second bracket means for mounting on opposite inner-facing surfaces of a doorway frame; and means for engaging the first and second bracket means to said first and second ends of the first horizontal member.
Claim 2
Dependent Claim
296 words
A portable support bar assembly for mounting about a doorway comprising a first elongated member having a first end and a second end; a first substantially V-shaped member having an upper leg joined to a lower leg, said V-member being engaged at a vertex formed by said upper and lower legs to the first horizontal elongated member adjacent said first end thereof, the first V-shaped member having a first stub projecting from said lower leg, said first stub being parallel to the first horizontal elongated member and beyond the terminus of said first end; a second substantially V-shaped member having an upper leg joined to a lower leg, said V-shaped member being engaged at a vertex formed by said upper and lower legs to the first horizontal elongated member adjacent said second end thereof, the second V-shaped member having a second stub projecting from said lower leg, said second stub being parallel to the first horizontal member and beyond the terminus of said second end; a second horizontal elongated member having a first end and a second end and engaged about its said first end to the upper leg of the first V-shaped member and about its said second end to the upper leg of the second V-shaped member; a first cross strut engaged about said first end of the second horizontal elongated member and about said lower leg of said first V-shaped member; a second cross strut engaged about said second end of the second horizontal elongated member and about said lower leg of said second V-shaped member; a first and second bracket means for mounting on opposite inner-facing surfaces of a doorway frame; and means for engaging the first and second bracket means to said first and second ends of the first horizontal member.
Claim 3
Dependent Claim
76 words
The portable support bar assembly of claim 1 wherein the first horizontal elongated member comprises a first and a second tubular member, with said first member being slidable within said second member in a telescoping fashion; and the second horizontal elongated member comprises a first and a second tubular member with said first tubular member being slidable within said second tubular member in a telescoping fashion; whereby the first and second horizontal members may be telescoped.
Claim 4
Dependent Claim
93 words
The portable support bar assembly of claim 1 or 2 wherein the first V-shaped member is engaged to the first horizontal elongated member with said upper leg of the first V-shaped member projecting upwardly and outwardly from the first horizontal elongated member; and the second V-shaped member is engaged to the first horizontal elongated member with said upper leg of the second V-shaped member projecting upwardly and outwardly from the first horizontal elongated member; whereby the second horizontal elongated member is elevated, parallel and projecting outward relative to the first horizontal elongated member.
Claim 5
Dependent Claim
106 words
The portable support bar assembly of claim 1 or 2 wherein the first and second bracket means each include a flat plate section within a first plane, a U-shaped guideway within a second plane parallel with and adjacent to said first plane and a support supporting said plate and guideway in place with a spacing intermediate the width of said guideway being at least equal to the outer cross-sectional dimension of the first elongated member; and the first elongated horizontal member being flared about its said first and second ends with the cross-sectional dimension of said flares each being greater than said width of said guideway.
Claim 6
Dependent Claim
185 words
The portable support bar assembly of claim 2 wherein the first V-shaped member is engaged to the first horizontal elongated member with said upper leg of the first V-shaped member projecting upwardly and outwardly from the first horizontal elongated member; and the second V-shaped member is engaged to the first horizontal elongated member with said upper leg of the second V-shaped member projecting upwardly and outwardly from the first horizontal elongated member whereby the second horizontal elongated member is elevated, parallel and projecting outward relative to the first horizontal elongated member; the first and second bracket means each include a flat plate section within a first plane, a U-shaped guideway within a second plane parallel with and adjacent with said first plane and a support supporting said plate of guideway in place with a spacing intermediate the width of said guideway being at least equal to the outer cross-sectional dimension of the first elongated member; and the first elongated horizontal member being flared about its first and second ends with the cross-sectional dimensions of said flares each being greater than said width of said guideway.
Claim 7
Dependent Claim
66 words
The portable support bar assembly of claim 1, 2 or 5 further including a first bumper means engaged to said stub of said first V-shaped member for cushioning the interface of said stub with the surface of a doorframe; and a second bumper means engaged to said stub of said second V-shaped member for cushioning the interface of said stub with the surface of a doorframe.
