Abstract: A cart for one or two hikers to transport their backpacks and having a single pneumatic tire mounted on a wheel with a double elongated aluminum tubular frame including support braces and rubber padded angular pack brackets enclosing the wheel. Easily adjustable and removable front and rear pairs of handles permit the hikers to direct, propel, and balance the cart, allow infants' seats to be attached thereto, and to store or transport the cart. The wheel is spring-mounted to the frame by means of double concentric steel tubes, the outer one containing a compression spring. A stretched nylon mesh covers the frame to keep pack straps from interfering with the wheel. An accurate mileage counter is mounted to the load angular bracket and belt-connected to the hub of the wheel.

Abstract: A mobile travel trunk is described including a water tight trunk or trailer compartment including a load adjustable suspension system. The forward end of the travel trunk includes a hitch assembly which is adapted to be secured to the bumper of a vehicle or the like. The rearward end of the trunk has a trapezoidal shaped opening which is defined by a U-shaped lip extending around three sides thereof. A spring loaded trapezoidal shaped door is pivotally mounted to the lower end of the rear wall of the trunk and includes a U-shaped lip which is adapted to be received by the U-shaped lip extending around the opening. When the door is in its closed position, a compression latch assembly causes the door to compress a resilient seal member extending around the door opening to provide a water tight and dust proof seal. The suspension system may be easily removed from the travel trunk to enable the travel trunk and the suspension system to be separately stored.

Abstract: A trailer hitch structure for coupling a single-wheel trailer to a tow vehicle having a conventional hitch bar fixed thereto and projecting rearwardly thereof. There is provided a rigid adapter having a rear portion and a front portion fixedly connected to and spaced forwardly from the rear portion. The front portion has structure for snugly and rigidly fixedly coupling the front portion to the vehicle hitch bar. The adapter also has a pair of coupling portions mounted on the rear portion in spaced relationship along a direction which extends transversely relative to the direction of vehicle movement for releasably coupling the trailer to the adapter at a pair of sidewardly spaced locations.

Abstract: A mobile self-propelled chair includes a frame having at its top a pivotally mounted passenger seat and captively mounting for rotation about various possible axes a relatively large sphere, which supports the principal weight of the chair and user. Auxiliary support is provided by casters surrounding the sphere. The frame has a battery and one or more drive motors for producing rotation of the sphere by drive roller engagement of the sphere surface. Posturally-effected movement of the seat actuates switches to provide power to the motor. Various arrangements allow orienting the axis of rotation of the sphere to cause turning the chair. Thus, both translation and turning movement of the chair is posturally controlled by the user.

Abstract: In conjunction with a cycle trailer having a frame the front reach of which consists of round tubing or bar, a universal-joint hitch consisting essentially of two diametrically opposed sector bearings which are constrained to bear upon the aforesaid tubing or bar of the frame from opposite directions by suitable clamping and mounting arrangements which include thrust surfaces integral to the sector bearings.

Abstract: A recreational toy wheel vehicle comprises a generally annular outer wheel member having an outer peripheral rolling surface and a generally smooth inner peripheral surface area defining a generally circular, axially extending interior cavity. A carriage member has a passenger carrying seat and a series of generally smooth rib members which contact the generally smooth inner surface area of the wheel member. The generally smooth inner surface area of the wheel member and the generally smooth rib members are fabricated of materials which minimize the coefficient of sliding, or kinetic, friction therebetween. Relatively frictionless or gliding contact between the two materials thus occurs, so that the carriage member is supported in a non-rotating position within the interior cavity during rotation of the outer wheel member on the rolling surface.

Abstract: A single wheel support for a vehicle-towed trailer. The support includes a swivel plate mounted on the trailer for swiveling about an upright axis. An elongate arm assembly is mounted adjacent one of its ends on the swivel plate for swinging about a horizontal swing axis. The wheel in the support is rotatably mounted on the other end of the assembly rearwardly of the swing axis. The arm assembly is biased in a direction opposing the weight of the trailer by a coiled spring compressibly interposed between the plate and a back region of the arm assembly, and by a coiled spring under tension interposed between the plate and a front region of the assembly.

Abstract: A bicycle trailer having reduced transverse profile and horizontal frame work with load carriage concentrated over the trailer wheel. The device utilizes a horizontal frame work as fork-supported above a standard bicycle wheel and having a tongue assembly formed integral with the trailer frame. The tongue assembly is then pivotally attached over a hitch plate that is vertically pivotally attached via T-connectors to each rear fork member of the associated bicycle.

Abstract: A sulky characterized by a single supporting wheel positioned behind, or partly beneath, the frame of the sulky, and where the driver's seat is positioned behind the single supporting wheel for added weight concentration and better driving control. The frame has a generally U-shaped plan configuration, unlike the present bow shape, and is typically made from a light weight metal which decreases in vertical dimension in a direction towards the head of the pulling horse.

Abstract: A collapsible pack cart comprises first and second frame members pivotally joined together and movable with respect to one another between an operating position, where they are oriented perpendicular to one another, and a folded position, where they are oriented laterally side by side and separated by a spaced distance. A wheel is carried rotatably by a carriage which is mounted to the frame members releasably in either an operative position where the wheel extends substantially perpendicular to the planes of both frame members when they are in their operating position, or a storable position where it is located entirely between the frame members when they are in their folded position. Support arms are attached releasably to that frame member which carries the wheel, and handles are attached to the other frame member for manipulation of the cart.

Abstract: A utility trailer for towing behind a vehicle, for uses such as carrying a motorcycle. The frame is rectangular and comprised of tubular members, with longitudinal channels on top of the tubular members for receiving motorcycle wheels. A detachable castor wheel supports the frame and is connected to it by means of leaf springs attached to the wheel on opposite sides. Two hitches for connecting the trailer to a vehicle are spaced apart on the forward end of the frame. Each hitch has two tabs, one connected to the vehicle and one to the frame that are coupled together by a pin. The hitch portion that is connected to the frame is L-shaped so that it can be inverted to change the height for different vehicle sizes. The mounting system for securing motorcycles includes a pair of telescoping tubes that are threaded together so that their combined length may be varied.

Abstract: A transporter comprising a pair of spaced hoops interconnected by a plurality of generally U-shaped spokes extending inwardly from the inner diameter of the hoops to form a central, generally circular opening. In order to provide a load carrying enclosure, band means such as ropes, chains, or cables are wrapped substantially around the central portions of the spokes. An opening is provided between any two adjacent spokes by not extending the bands entirely around all the spokes so that items may be placed into the load carrying enclosure. When the enclosure is full a load retaining means such as a tightener is fastened across the opening to pack the items together tightly and render them ready for transportation by rolling the transporter along a surface.

Abstract: A cart for two hikers to transport a load includes a single wheel with an elongate frame disposed directly over the wheel. Braces supporting the frame on the wheel extend closely adjacent the wheel to minimize the width. Handlebars at opposite ends permit the hikers to direct and propel the cart. A pair of containers are hooked over the frame on opposite sides of the wheel for carrying the load.

Abstract: The present invention concerns a collapsible containing device for bulk transport and storage of liquid and solid cargo and is characterized as having as its primary containing means a flexible, high strength bag or sleeve capable of collapsing within its supporting frame to a compact configuration.
