A system, generally for use with light personal vehicles such as bicycles or e-bikes, for enabling a vehicle trailer and a tow bar to be interconnected in either a braking configuration or a non-braking configuration, is described. Also described is a braking kit for interconnecting a tow bar and a vehicle trailer in a braking configuration, wherein the vehicle trailer comprises a connection interface dimensioned to be connected with an end of the tow bar in a non-braking configuration. When the tow bar and the trailer are interconnected in the braking configuration, at least a threshold amount of rearward force imparted via the tow bar during vehicle braking causes the actuation of at least one brake associated with the trailer wheels. The same tow bar can be used in either braking or non-braking configuration.

Embodiments of the present disclosure relate to a immersive digital advertising system and method thereof for providing one or more local merchants the ability to expand their advertising outreach to local and nearby consumers via digitally displayed advertisements, the system having an electric pod cargo trailer and an electric tow bicycle coupled to the electric pod cargo trailer for hauling the electric pod cargo trailer along a predetermined Ad pedestrian route.

The invention is related to the class of small-scale tracked transportation vehicles, which can be used for towing a person and cargo using a sledge, for example. The motorized towing vehicle comprises a frame supporting a caterpillar drive, a platform supporting an engine with a transmission, a luggage space, an assembly for connecting to the object being towed object, a control device, and an object being towed. The caterpillar drive includes a caterpillar track, a metal subframe, a driven shaft and a driving shaft with pinions, and torsion-type wheel bogie. The control device consists of a steering wheel with handles and controls. The object being towed comprises a driver's workplace. The frame consists of a platform and a rigid framework enclosing the platform along the entire perimeter, including the luggage compartment with an additional luggage space above. The design of the frame and platform is asymmetrical relative to the track because of an extension of the platform in one direction. The subframe is in the form of metal side plates connected to the frame with brackets bent into an S-shape. The subframe plates accommodate a track tightening mechanism in the form of an eccentric and self-aligning bearings. An all-weather hood is used for protecting the engine and luggage space. The road performance of the motor towing vehicle has been improved.

A vehicle for transporting persons and/or goods, having at least one frame which includes of at least one frame element which extends substantially parallel or obliquely to the longitudinal direction of the vehicle, at least one wheel carrier which can be detachably secured to the frame element and which, together with the frame element, forms a receiving region between the wheel carrier and the frame element. The wheel carrier and the frame element are spaced apart from one another at least in sections so as to form a cavity. The frame also includes at least one wheel unit which includes a wheel and can be fixed or is fixed in a rotatably mounted manner at least in sections in the receiving region between the wheel carrier and the frame element.

Disclosed is a bike trailer having a main frame and a seat structure. The main frame defines an accommodating space for a passenger or load to be transported. The seat structure is transferable between an operational state in which the seat structure forms a seating area for the passenger, and a stowed state in which the seat structure is folded away thereby allowing the transport of loads other than passengers. The seat structure comprises a backrest portion with a seating side for at least partially contacting the back of a passenger. The backrest portion is accommodatable in the bike trailer such that at least the seating side of the backrest portion is protected against contact with loads to be carried when the seat structure is in the stowed state.

A foldable frame structure for trailer so designed that the distance between the pivot connection center of each pivot holder and the left/right side frame and the topmost edge of the left/right frame bar of the bottom frame is greater than the distance obtained by deducting the width of the collapsed bottom frame from the height from the left/right frame bar of the bottom frame to the topmost edge of the left/right side frame. Thus, the left side frame and the right side frame can be individually collapsed and closely attached to the bottom frame in one step. The present invention can greatly save the transportation volume and simplify the folding structure and folding action, and thus achieve the purpose of user's convenient collection and carrying.

A trailer apparatus is provided having two half forms connected to a frame joint, the half forms mounted on a first and second pivot bar on the joint frame to pivot to open and to pivot to close in a clam shell arrangement. The trailer apparatus may assume a form of backpack or luggage piece adapted to store items and may assume the form of a towable trailer, having a tow bar, wheels, and a three-dimensional covering over the open sides of the half forms to enclose cargo space or to keep a pet inside the footprint of the half form adapted as trailer bed when the trailer apparatus is extended for use.

A bracket, which can be in the form of first and second bracket members, desirably projects outwardly from the trailer frame and includes a bracket passageway. A housing includes a housing passageway extending at least partially through the housing and that communicates with the exterior of the housing through a locking insert receiving opening. The locking insert receiving opening, the housing passageway and the bracket passageways define a locking insert receiving passageway. A locking insert couples the housing to the bracket and thereby to the trailer frame. The locking insert includes an accessory arm receiving passageway communicating with the housing exterior through the locking insert receiving opening.

A bicycle seat recline adjusts the incline of a bicycle trailer seat back. The seat recline can comprise opposed gear racks engaged by gears at opposite ends of a cross member. The cross member is coupled to an upper portion of the seat back. Moving the cross member moves the gears in the gear racks and adjusts the angle of the seat back. The cross member is desirably selectively and simultaneously lockable to and releasable from any one of a plurality of positions along the gear rack. A lower portion of the seat back can pivot about a lower pivot axis. The gear racks can be arced to maintain a constant distance to the lower pivot axis as the cross member is moved and maintains a constant tension on the seat back. A plurality of seats with adjustable seat back reclines can be included in the bicycle trailer.

A cart assembly adapted for manual, bicycle and/or motorized vehicle towing. Multiple frame sections are coupled to pivot between completely collapsed, partially open and completely open positions to facilitate, travel, storage and sleeping. A pair of axle plates support primary wheels to the framework and a drive axle between adjacent cross-brace arms. A handle frame section, saddle arms, truss arms, resilient spreader arms, auxiliary caster wheel, battery powered electric drive motor(s), fabric cover and/or hard cover mount to the framework. A resilient, reciprocating shock absorbing tow bar or tongue arm assembly provides flexibly resilient pieces to absorb travel shock between the cart and tow vehicle.
