Tow bar arrangement (100) for interconnection of a pulling vehicle (10) and a pulled trailer (20). The arrangement (100) comprises a control device (110) with a force sensor (111) arranged to sense an instantaneous relative force between vehicle (10) and trailer (20). The control device (110) is arranged to produce a control signal for an electric motor (21) arranged to propel the trailer (20) so that a motor force counter-acts said measured force. The invention is characterised in that the control device (110) is arranged to a first time series of force measurements, in that the control device (110) comprises a low-pass filter (112) producing a second low-pass filtered time series, and in that a regulator (113) is ar-ranged to regulate said second time series to produce said control signal.

Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

A child transport carrier includes a lower frame, an upper frame, a rear frame, and a first upper seat support. The lower frame includes a first end and a second end. The upper frame includes a first end and a second end. The rear frame extends from the second end of the lower frame to the second end of the upper frame. The first upper seat support includes a cross-member extending transversely across the first upper seat support and having a first end and a second end. The cross-member is configured to move the first upper seat support between a first seat position and a second seat position. The upper frame extends from an upper end of the rear frame and the lower frame extends from a lower end of the rear frame.

A cart/trailer, yoke mechanism, and hitch mechanism are disclosed. The cart/trailer could be an assembly for moving and transporting objects comprising a tow bar (synonymous herein with a handle or kickstand); a variable-positioning yoke assembly for facilitating the placement of the tow bar into positions of a towbar, handle, or kickstand; and a main structure within which equipment such as sporting accessories may be placed for transport for moving and transporting objects. The coupling device could include a main body with an inner surface, and a pair of opposing flanges extending downwardly and substantially perpendicularly away from the main body for facilitating the positioning of the yoke in variable positions. The hitch mechanism could include a hitch and interface with receiver and hitch portions for facilitating the hitching of the cart/trailer to a mobility device.

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 fried food cart assembly for preparing fried treats in any location includes a cart that has a hitch which is coupled to the cart. A fryer is positioned in the cart to heat cooking oil for frying a food item. A cold storage unit is positioned in the cart to store perishable food items. A plurality of preparing shelves is each positioned in the cart to facilitate objects to be placed thereon. A point of sale unit is positioned in the cart to conduct financial transactions for patrons purchasing food that is prepared in the cart. An umbrella is positionable in the cart to shield the cart from precipitation and sunlight.

A child transport carrier includes a lower frame, an upper frame, a rear frame, and a first upper seat support. The lower frame includes a first end and a second end. The upper frame includes a first end and a second end. The rear frame extends from the second end of the lower frame to the second end of the upper frame. The first upper seat support includes a cross-member extending transversely across the first upper seat support and having a first end and a second end. The cross-member is configured to move the first upper seat support between a first seat position and a second seat position. The upper frame extends from an upper end of the rear frame and the lower frame extends from a lower end of the rear frame.

Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

The present invention relates to a cart (1) for use as a bicycle trailer (1) or as a handcart (1) with a frame (10) with a pair of wheels (13) and with a loading surface (14) and with a foldable drawbar (3) with a drawbar body (33) which is designed to be connected to a bicycle in a first position and to be guided by a user's hand in a second position. The cart (1) is characterized in that the foldable drawbar (3) has a drawbar holder (30) arranged on the frame (10), the drawbar holder (30) being designed with the draw-bar body (33) in the first position and in the second position. The present invention also relates to a cart (1) for use as a bicycle trailer (1) or as a handcart (1) with a frame (10) with a pair of wheels (13) and with a loading surface (14) and with a fold-out stand (2). The cart (1) is characterized in that the fold-out stand (2) has a stand holder (20) which is arranged on the frame (10) and a stand element (24) which is held in a foldable manner by the stand holder (20), the stand holder (20) having a recess (21) within which the stand element (24) can be hinged between a folded state and an unfolded state.

A moving body includes: a vehicle which includes a front wheel and rear wheels and which a passenger gets on; an unmanned carrier vehicle which is arranged at the back side of the vehicle, and includes a wheel and a driving unit which drives the wheel; and a coupler which couples the vehicle and the unmanned carrier vehicle. The coupler includes a biasing mechanism which biases a rear part of the vehicle toward an upper side of the vehicle, the biasing mechanism includes a first elastic member; when the passenger is on the vehicle, the first elastic member is deformed by the weight of the passenger to place the rear wheels in contact with a road surface, and when the passenger is not on the vehicle, the rear wheels are separated from the road surface by the elastic force of the first elastic member.
