Claim 3

A back pack frame comprising: (a) a frame member having a frame perimeter member, the said frame perimeter member having two generally vertical sides and two generally horizontal sides connecting the said vertical sides, said vertical perimeter member sides each being constituted by two closely spaced parallel respective portions of first solid wire providing corresponding slot portions between them, and said horizontal perimeter member sides each also being constituted by respective portions of first solid wire; (b) a wire frame grid extending between the said frame perimeter member sides and connected thereto, the wire frame grid comprising: a plurality of spaced second solid wires extending between the perimeter member sides and fastened at their ends thereto; a plurality of spaced third solid wires extending between the perimeter member sides transverse to the plurality of second wires and fastened at their ends to the perimeter member sides; the said two closely spaced first wire portions being fastened to the second and third wires at each junction of a first wire portion with a second and third wire and the said second wires being fastened to the third wires at each junction of a second wire with a third wire; each of said solid first, second and third wires being individually bendable for adjustment of the frame shape, while providing the required rigidity for the entire frame as a result of their interconnection with one another, (c) a shoulder harness attached to the frame member; and (d) a belt harness attached to the frame member.

Claim 4

A back pack frame comprising: (a) a frame member having a frame perimeter member, the said frame perimeter member having two generally vertical sides and two generally horizontal sides connecting the said vertical sides, said vertical perimeter member sides each being constituted by two closely spaced parallel respective portions of first solid wire providing corresponding slot portions between them, and said horizontal perimeter member sides each also being constituted by respective portions of first solid wire; (b) a wire frame grid extending between the said frame perimeter member sides and connected thereto, the wire frame grid comprising: a plurality of spaced second solid wires extending between the perimeter member sides and fastened at their ends thereto; a plurality of spaced third solid wires extending between the perimeter member sides transverse to the plurality of second wires and fastened at their ends to the perimeter member sides; the said two closely spaced first wire portions being fastened to the second and third wires at each junction of a first wire portion with a second and third wire and the said second wires being fastened to the third wires at each junction of a second wire with a third wire; each of said solid first, second and third wires being individually bendable for adjustment of the frame shape, while providing the required rigidity for the entire frame as a result of their interconnection with one another, (c) a shoulder harness attached to the frame member; and (d) a belt harness attached to the frame member.

Claim 5

A frame as claimed in claim 1 or 2, wherein the said second wires are generally parallel to one another and to the said perimeter member vertical sides, and the said third wires are generally parallel to one another, generally parallel to the said perimeter member horizontal sides, and at right angles to the said second wires.

Claim 6

A frame as claimed in claim 1 or 2, wherein the frame member is vertically elongated with the said second wires generally parallel to one another and to the member vertical sides, and with the said third wires generally parallel to one another and to the frame member horizontal sides, the second wires being longer than the third wires.

Claim 7

A frame as claimed in claim 1 or 2, wherein the top horizontal perimeter member side also comprises two closely spaced parallel first wire portiions providing a corresponding slot portion between them, the said first wire portions both being fastened to the second and third wires at each junction of a first wire portion with a second and third wire.

Claim 8

A frame as claimed in claim 1 or 2, wherein the two slot portions formed between the closely spaced parallel wire portions at the bottom of the vertical sides are subdivided by supplementary wires extending between the said first wire portions and fastened thereto.

Claim 9

A frame as claimed in claim 1 or 2, wherein the belt harness is secured to the frame member by means of belts having thereon belt buckles which can be passed through a said slot portion only while in an edgewise attitude.

Claim 10

A frame as claimed in claim 1 or 2, wherein the shoulder harness is secured to the frame member by means of belts having thereon belt buckles which can be passed through a said slot portion only while in an edgewise attitude.

Claim 11

A frame as claimed in claim 1 or 2, wherein means for fastening the pack to the frame member comprise: a plurality of apertures in the pack member, a like plurality of headed pins, the shank of each of which can be passed through a corresponding slot portion and the head of which cannot, each pin having its shank passed through a pack aperture and a registering slot portion of the frame member, and means engaging each pin shank to prevent its withdrawal through the pack aperture and the registering frame member slot portion.

Claim 12

A frame as claimed in claim 1 or 2, wherein the said wire frame grid includes at least one pair of closely spaced parallel second wires extending generally parallel to the frame member vertical sides and providing corresponding slot portions between them.

Claim 13

A frame as claimed in claim 1 or 2, wherein the said shoulder harness and the said belt harness encircle the frame member and comprise adjustable strap means for tightening the harness around the frame member for application of transverse tension thereto.
