Abstract

Abstract A multiple function assembly used both as a seat and a back pack. The assembly includes two hinged-together sections that articulate over an arc of about 45 degrees. A seat pad is hinged to the free end of one section and a storage bag detachably engages the other section. When the seat pad is pivoted to a position parallel with the section to which it is attached, the assembly functions as a back pack. When it is pivoted to an obtuse angle, the assembly functions as a seat with a back rest.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 183 words
A multiple function assembly for use as a seat or back pack comprising: a frame assembly having a front section and a back section, means for hinging said front and back sections together for articulating relative movement in an arc of substantially 45 degrees between a storage position and a use position, a seat pad shaped and sized for storage in flat parallel relation to said front and back sections when said front and back sections are positioned in substantially parallel relation, said front and back sections being positioned parallel to one another with said seat pad therebetween when said assembly is in said storage position, means for securing said seat pad to said front section and permitting movement of said seat pad between said storage position and said use position wherein said seat pad extends at an obtuse angle with respect to said front section, a storage bag having at least one wall shaped and sized to substantially conform with said back section, and means for detachably inter-engaging said storage bag with its one wall in facing engagement with said back section.
Claim 2
Dependent Claim 183 words
A multiple function assembly for use as a seat or back pack comprising: a frame assembly having a front section and a back section, means for hinging said front and back sections together for articulating relative movement in an arc of substantially 45 degrees between a storage position and a use position, a seat pad shaped and sized for storage in flat parallel relation to said front and back sections when said front and back sections are positioned in substantially parallel relation, said front and back sections being positioned parallel to one another with said seat pad therebetween when said assembly is in said storage position, means for securing said seat pad to said front section and permitting movement of said seat pad between said storage position and said use position wherein said seat pad extends at an obtuse angle with respect to said front section, a storage bag having at least one wall shaped and sized to substantially conform with said back section, and means for detachably inter-engaging said storage bag with its one wall in facing engagement with said back section.
Claim 3
Dependent Claim 100 words
A multiple function assembly as set forth in claim 1 including a pair of shoulder straps sized to fit over an individual's shoulders for carrying said assembly, said shoulder straps each engaged at one end at the upper end of said frame assembly and at the other end at the lower end of said frame assembly, and adopted to be positioned in front of said front section when said assembly is in said storage position for carrying and over said back section when said frame assembly is in said use position for securing said frame assembly in said use position.
Claim 4
Dependent Claim 304 words
A multiple function assembly for use as a seat or back pack comprising: a frame assembly having a front section and a back section comprised of tubular members, each of said sections being U-shaped with the free ends of the legs of said U-shaped sections pivotally interengaged, means for hinging said front and back sections together for articulating relative movement in an arc of substantially 45 degrees between a storage position and a use position, said front and back sections forming an A-frame when in said use position and positioned in substantially parallel relation when in said storage position, a pair of shoulder straps positioned to engage said front and back sections to limit movement from said A-frame position, a seat pad shaped and sized for storage in flat parallel relation to said front and back sections when said sections are in said storage position, means pivotally securing said seat pad to the bight of said front section and permitting movement of said seat pad between said storage position and said use position wherein said seat pad extends at an obtuse angle with respect to said front section, said hinging means including means for offsetting the hinging axis of said front section from the plane in which said back section primarily rests to space said sections apart in substantially parallel relation when in said storage position with said space being at least substantially the thickness of said seat pad so that said front and back sections are positioned substantially parallel to one another with said seat pad therebetween when said frame assembly is in said storage position, a storage bag having at least one wall shaped and sized to substantially conform with said back section, and means for detachably interengaging said storage bag with its one wall in facing engagement with said back section.
Claim 5
Dependent Claim 304 words
A multiple function assembly for use as a seat or back pack comprising: a frame assembly having a front section and a back section comprised of tubular members, each of said sections being U-shaped with the free ends of the legs of said U-shaped sections pivotally interengaged, means for hinging said front and back sections together for articulating relative movement in an arc of substantially 45 degrees between a storage position and a use position, said front and back sections forming an A-frame when in said use position and positioned in substantially parallel relation when in said storage position, a pair of shoulder straps positioned to engage said front and back sections to limit movement from said A-frame position, a seat pad shaped and sized for storage in flat parallel relation to said front and back sections when said sections are in said storage position, means pivotally securing said seat pad to the bight of said front section and permitting movement of said seat pad between said storage position and said use position wherein said seat pad extends at an obtuse angle with respect to said front section, said hinging means including means for offsetting the hinging axis of said front section from the plane in which said back section primarily rests to space said sections apart in substantially parallel relation when in said storage position with said space being at least substantially the thickness of said seat pad so that said front and back sections are positioned substantially parallel to one another with said seat pad therebetween when said frame assembly is in said storage position, a storage bag having at least one wall shaped and sized to substantially conform with said back section, and means for detachably interengaging said storage bag with its one wall in facing engagement with said back section.
Claim 6
Dependent Claim 263 words
A multiple function assembly for use as a seat or back pack comprising: a frame assembly having a front section and a back section, means for hinging said front and back sections together for articulating relative movement in an arc of substantially 45 degrees between a storage position and a use position, a seat pad shaped and sized for storage in flat parallel relation between said front and back sections when said sections are positioned in substantially parallel relation in said storage position, means for securing said seat pad to said front section and permitting movement of said seat pad between said storage position and said use position wherein said seat pad extends at an obtuse angle with respect to said front section, stop means comprising at least one elongated member having one end secured to the free end of one of said front and back sections and the other end engaging said other section at said hinging means whereby said stop means may be selectively used as a carrier for said assembly when said assembly is in said storage position and as means for limiting articulating relative movement of said front and back sections when said assembly is in said use position, said stop means when used to limit articulating motion having an intermediate segment engaging the free end of the other of said sections, a storage bag heaving at leat one wall shaped and sized to substantially conform with said back section, and means for detachably inter-engaging said storage bag with its one wall in facing engagement with said back section.
Claim 7
Dependent Claim 263 words
