Abstract
A stable lightweight cargo trailer for a bicycle with a demountable bicycle type wheel having a collapsible frame assembly, the trailer including an upper elongate frame member defining an upper limit of a cargo compartment and a lower frame member having a portion defining a lower limit of the cargo compartment, the upper frame member and the lower frame portion being pivotally connected by intermediate end and side members such that the upper frame member is foldable from an extended position to a collapsed position allowing the upper frame member to collapse to overly said lower frame member into a compact configuration.
Claims23
A folding trailer comprising:
- an upper generally rectangular structural frame member defining the upper limit of a cargo compartment;
- a lower continuous frame member having a substantially rectangular portion complementary to said upper frame member defining a lower limit of said cargo compartment;
- a pair of substantially identical folding side support frame members connected intermediate said upper and said lower frame members;
- front and rear folding support frame members connected intermediate said upper and said lower frame members at the front and rear ends thereof;
- said side frame members and said front and rear frame members including pivot means for providing that said upper frame member is foldable from an extended position to a collapsed position allowing the upper frame member to fold downwardly to overly said lower frame member into a compact configuration;
- and
- wherein said substantially identical side frame members include a top portion pivotally connected to said upper frame member and a bottom portion releasably connected to said lower frame member whereby upon release from said lower frame assembly said side members are foldable inwardly and upwardly to a position generally parallel with said upper frame member.

A folding trailer comprising:
- upper and lower frame members each defining upper and lower limits of a cargo compartment;
- front and rear support frame members connected intermediate said upper and said lower frame members defining the front and rear of said cargo compartment, each said front and rear member having a top portion pivotally connected to the respective end of said upper frame member and a bottom portion pivotally connected to the corresponding end of said lower frame member;
- side frame members connected intermediate said upper and said lower frame members defining the sides of said cargo compartment, each said side member having a top portion pivotally connected to the respective side of said upper frame member and a bottom portion releasably connected to the corresponding side of said lower frame member;
- and
- whereby upon release from said lower frame assembly said side members are foldable inwardly and upwardly to a position parallel with said upper frame member;
- and said upper frame member is foldable from an extended position to a collapsed position to overly said lower frame member into a compact configuration.

A folding trailer comprising:
- an upper elongate frame member having a front end and a rear end and defining an upper limit of a cargo compartment;
- a lower frame member having a portion thereof defining a lower limit of said cargo compartment, said portion having a front end and a rear end;
- folding front and rear support frame members connected intermediate said upper and said lower frame members defining the front and rear of said cargo compartment, each said front and rear member having a top portion and a bottom portion, the top portion of each pivotally connected to the respective end of said upper frame member and the bottom portion of each pivotally connected to the corresponding end of said lower frame member;
- folding side frame members connected intermediate said upper and said lower frame members defining the sides of said cargo compartment, each said side member having a top portion and a bottom portion, the top portion of each pivotally connected to the respective side of said upper frame member and the bottom portion of each releasably connected to the corresponding side of said lower frame member;
- said side members and said front and rear folding frame members including pivot points such that upon release of said bottom portions of said side members, said upper frame member is foldable from an extended position to a collapsed position allowing said upper frame member to collapse to overly said lower frame member into a compact configuration;
- means extending rearwardly of said lower frame member for supporting a wheel;
- and wherein said front and rear folding frame members are comprised of H-shaped support frames pivotally coupling said upper and said lower frame members at respective ends, said H-shaped support frames including first and second upright side tubes and an interconnecting cross-tube, the top two upright tubes in each case pivotally connected to said upper frame and the bottom two upright tubes pivotally connected to said lower frame portion.

A folding trailer comprising:
- an upper generally rectangular structural frame member defining the upper limit of a cargo compartment;
- a lower continuous frame member having a substantially rectangular portion complementary to said upper frame member defining a lower limit of said cargo compartment;
- a pair of substantially identical folding side support frame members connected intermediate said upper and said lower frame members;
- front and rear folding support frame members connected intermediate said upper and said lower frame members at the front and rear ends thereof;
- said side frame members and said front and rear frame members including pivot means for providing that said upper frame member is foldable from an extended position to a collapsed position allowing the upper frame member to fold downwardly to overly said lower frame member into a compact configuration;
- and
- wherein the front of said lower frame and said front support frame support member each include connector means for attachment of said hitch means, said hitch means formed of tubular material and including a hollow portion configured for fitting between said connector means for receiving therethrough a rod having a thumb screw head and a threaded end for threadable attachment to the connector means of the lower frame, said hollow portion having welded thereto the curved portion of a first U-shaped member proximate the top end thereof and the curved portion of a second U-shaped member proximate the bottom thereof, the open ends of said first U-shaped member attached to a respective side of the axle of the bicycle rear wheel, and the open ends of said second U-shaped member welded to said first U-shaped member proximate said axle.
4 more elements
A folding trailer comprising:
- an upper elongate frame member having a front rail, a rear rail, and two substantially identical side rails and defining an upper limit of a cargo compartment;
- a lower frame member having a portion thereof defining a lower limit of said cargo compartment complementary with said upper frame member and having a front rail, a rear rail, and two substantially identical side rails;
- a pair of folding side frame members connected intermediate said upper and said lower frame members, each of said side members pivotally connected to a respective side rail of said upper frame member and releasably connected to the corresponding side rail of said lower frame member whereby upon release from said lower frame member said side frame members are foldable inwardly and upwardly to a position generally parallel with the plane of said upper frame member;
- front and rear folding frame members connected intermediate said upper and said lower frame members, each having a top end and a bottom end, the top end of said front member pivotally connected to the front rail of said upper frame and the bottom end pivotally connected to the front rail of said lower frame member, and the top end of said rear frame member pivotally connected to the rear rail of said upper frame and the bottom end pivotally connected to the rear rail of said lower frame member;
