ABSTRACT:
BACKGROUND OF THE INVENTION
The background of the invention will be discussed in two parts.
1. Field of the Invention
This invention relates to trailers for bicycles, and more particularly to a single wheel bicycle towed trailer assembly, which trailer is lightweight and collapsible for storage or transportation.
2. Description of the Prior Art
Trailers for use with bicycles are well known in the art. There are many varieties of such trailers, which have taken many forms. In some such trailers, infant or toddler carrying vehicles have generally taken the form of two-wheeled trailers configured with a conventionally seating area for the occupant. Other such devices are configured for transportation of miscellaneous cargo as may be desired by the bicycle rider. Whether configured for carrying small children or transporting cargo, such trailers are usually designed for towing behind the bicycle and attachable in some manner to the rear wheel of the bicycle.
In accordance with an aspect of the invention, there is provided a trailer towable from the rear wheel of a bicycle for transporting cargo, the trailer having a removable single wheel and a collapsible foldable frame for ease of storage or transportation.
SUMMARY OF THE INVENTION
According to a broad aspect of the invention there is provided a compact, stable and lightweight trailer, configured and dimensioned to define a cargo enclosure, for attachment to the rear wheel of a bicycle and having a collapsible, or folding frame assembly. The frame assembly comprises a primary structural tubular frame assembly including an upper continuous generally rectangular frame member, a lower frame member having a continuous generally rectangular portion, a front and a rear H-shaped support frame formed of first and second upright articulated tubes with an interconnecting cross-bar pivotably coupled intermediate the upper and lower frame members at the front and rear thereof, left and right side folding support frame units pivotally coupled at the tops thereof to the left and right side, respectively, of the upper frame member and releasably connected at the bottoms thereof to the left and right side, respectively, of the lower frame member, and a lower base or floor member, all of which cooperatively define the cargo enclosure.
The front and rear support frame units are pivotally coupled to both the upper and lower frame members whereas the side units are pivotally coupled to the upper frame member and releasably connected to the lower frame member by suitable releasable couplers for enabling captive, yet releasable retention of the two side frame units. Upon release of the releasable couplers, the upper frame member folds rearwardly to collapse onto the lower frame member.
Also included is a pair of generally parallel fork members extending from the rear of the generally rectangular portion of the lower frame unit for supporting a removable wheel having a pneumatic tire, and a horizontally pivotable hitch arm assembly attached at the front of the primary frame assembly for attachment to the rear wheel of a bicycle.
Other objects, features and advantages of the invention will become apparent from a reading of the specification, when taken in conjunction with the drawings, in which like reference numerals refer to like elements in the several views.
