Collapsible carriers

A carrier configured to enable a person to carry cargo on their back, comprising:

• A) a frame assembly comprising:
• i) a first frame member having a top, a bottom, and a mounting plate;
• and
• ii) a second frame member having a perimeter, a proximal end, a distal end, a central section comprising a framework disposed between said proximal and said distal ends,
• said proximal end having a loop at which said second frame member is hingedly attached to said first frame member at said mounting plate, said loop having a bend adjacent thereto that provides a contacting portion that contacts said mounting plate when said second frame member is pivoted to an extended position with respect to said first frame member, sufficiently to limit the span of travel of said second frame member with respect to said first frame member by such contact, such contacting portion also providing supportive force for a load present on said framework when said second frame member is in an extended position said bend, said loop and said central section all being provided by virtue of said perimeter of said second frame member being comprised from a single piece of bent linear stock, and
• B) a shoulder harness attached to said frame assembly, said harness having shoulder straps configured to be received by the arms of a person sufficiently to enable said person to wear said harness on their back, said harness being further configured to receive and securely maintain said first frame member in a substantially vertical orientation when said person is in an upright, vertical standing position wearing said carrier.

A carrier useful to enable a person to carry a child on their back, comprising:

• A) a frame assembly having:
• i) a first frame member having a top, a bottom, a width dimension, and two end portions, wherein said bottom of first frame member is open, and wherein the distance between said end portions is less than said width;
• ii) a second frame member having a perimeter, a proximal end, a distal end, a central section comprising a seat disposed between said proximal and said distal ends, and a contacting portion,
• said proximal end of said second frame member being hingedly attached to said first frame member between said two ends,
• said contacting portion being present as two bends on said second frame member at said proximal end, said contacting portion being configured to contact said first frame member when said second frame member is pivoted to an extended position with respect to said first frame member, sufficiently to limit the span of travel of said second frame member with respect to said first frame member by such contact, such contacting portion also providing supportive force for a load present on said seat when said second frame member is in an extended position,
• wherein said central section of said second frame member exists in a first plane, and said distal end of second frame member exists in a second plane that angles upwardly from said first plane;
• and
• B) a shoulder harness attached to said frame assembly, said harness having shoulder straps configured to be received by the arms of a person sufficiently to enable said person to wear said harness on their back, said harness being further configured to receive and securely maintain said first frame member in a substantially vertical orientation when said person is in an upright, vertical standing position wearing said carrier.
