ABSTRACT:
FIELD OF INVENTION
This invention relates to trailers adapted to be towed behind bicycles. More particularly this invention relates to a lightweight bicycle trailer which may be collapsed for storage, shipping and transportation in a vehicle.
BACKGROUND OF THE INVENTION
Avid cyclists enjoy participating in full day, overnight, and even cross country tours of several days duration. For these longer rides more gear is required. A small volume of gear may be carried behind a bicycle seat. More gear must be carried in a back pack. It is more convenient and less burdensome to carry this additional gear in a bicycle trailer.
Like a good bicycle, a good bicycle trailer should be adequately strong and as light as possible. It should also be easily attached to, and removed from a bicycle. It is desirable if the bicycle can be laid down while remaining attached to the trailer. Most of the time the trailer is not in use. If the trailer is collapsible for storage, shipping and transportation it is much more convenient to keep and use.
OBJECTS AND STATEMENT OF INVENTION
It is an object of this invention to disclose an unusually light bicycle trailer. It is yet a further object of this invention to disclose a trailer which may be readily collapsed for shipping and transportation, and a trailer which may be dissembled for ultimately convenient delivery and winter storage. It is yet a further object of this invention to disclose a trailer which may be quickly and easily attached to a bicycle. It is a final object of this invention to disclose a bicycle trailer hitch which not only is unusually quickly attached or unattached from a bicycle, but additionally is so flexibly that a bicycle can be laid down while remaining attached to a trailer standing in an upright position.
One aspect of this invention provides for a bicycle trailer for attachment to the frame of a bicycle comprising: a trailer frame having two rectangular members, each rectangular member having opposite end portions which are centrally and pivotally attached to the opposite end portions of the other rectangular member, and each rectangular member having a lower side portion extending generally horizontally along one lower side portion of the trailer and an upper side portion extending generally horizontally along an upper side portion of the trailer; spacing maintenance means extending between the two rectangular members; a tongue member having a rear end portion attached to a front end portion of the trailer frame; a central portion extending forwardly, and a front portion; a releasable hitch having a bicycle frame mounted portion which is carried by the bicycle frame, and a releasable portion which is attached to the front portion of the tongue member; a trailer bottom portion extending between the lower side portions of the rectangular frame members; and, wheels each rotatingly mounted to an opposite central portion of the lower side portion of the trailer frame.
Another aspect of this invention provides for a trailer as above wherein the trailer frame comprises tubing and wherein the upper and lower side members of the rectangular frame members of the trailer comprise breaks therethrough and wherein one end of the tubing adjacent to the break has a reduced diameter so that it may be inserted within the other end of the tubing adjacent to the break so that the rectangular frame members may be disassembled.
Various other objects, advantages and features of novelty which characterize this invention are pointed out with particularity in the claims which form part of this disclosure. For a better understanding of the invention, its operating advantages, and the specific objects attained by its users, reference should be made to the accompanying drawings and description, in which preferred embodiments of the invention are illustrated.
