The present disclosure relates to a stroller comprising: a sheet portion including a sheet; a support frame including an upper support frame supporting the sheet, a lower support frame rotatably connected to the upper support frame by a hinge portion, and a frame support that maintains a fixed state between the upper support frame and the lower support frame; and a moving structure to which the support frame is detachably connected, the moving structure including a guide frame that allows the lower support layer to fold and support and is extended in the length direction, a drive frame including a rear wheel coupling portion having a front wheel coupling portion connected in a ‘¬’ shape to the front part of the guide frame and a rear wheel coupling portion having coupling shaft portions formed on both sides of the rear end of the guide frame, a front wheel supported by a support fork to be installed on the front wheel coupling portion, and a rear wheel installed on the rear wheel coupling portion through a rear wheel connecting shaft.

An apparatus includes a support frame structure for supporting a walking aid. A seating device supports a toddler in a sitting or standing position. A tether implement secures the seating device to the support frame structure, wherein the frame members stabilize the apparatus on a supporting surface. A plurality of wheels disposed at a base of each of the plurality of frame members provides mobility on the supporting surface. L-shaped extensions are configured to extend each of the plurality of wheels further out than the support frame structure. A braking mechanism disposed on an underside of each L-shaped extension is configured to generally stop a movement of the apparatus or a rotation of the wheel when the wheel is no longer supported by the supporting surface. A handle implement disposed on the support frame structure is configured to be operable for steering the apparatus.

In an aspect, a pivot joint for a collapsing foot-deck-based vehicle is described, comprising a foot deck, at least two wheels coupled to the foot deck, and a handlebar assembly coupled to the foot deck via a locking pivot joint, also referred to as a locking swivel joint, the handlebar assembly comprising at least one handle, the locking pivot joint having a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels, the handlebar assembly being selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck and a collapsed configuration in which the handle is generally proximal to the foot deck.

In an aspect, a collapsing foot-deck-based vehicle is provided and includes a foot deck, at least two wheels coupled to the foot deck, and a handle structure coupled to the foot deck via a locking pivot joint. The handle structure includes at least one handle. The locking pivot joint has a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels. The handle structure is selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck for gripping by a rider of the foot-deck-based vehicle, and a collapsed configuration in which the handle is generally proximal to the foot deck.

A foldable personal such as a tricycle which can be convertible into a stroller, is configured for accommodating a child therein and for preventing, when desired, the child from being able to steer the vehicle, vehicle having an operational state and a storage state, in which it can take an extremely compact form. The vehicle has a longitudinal axis lying in its vertical plane of symmetry and having a horizontal reference plane perpendicular to the plane of symmetry, and it takes its compact form in the storage state both in the direction along its longitudinal axis and in the directions perpendicular to this axis both along the plane of symmetry and perpendicular to the plane of symmetry.

A ridable kart can have a body that supports a front wheel and movable rear wheels. The kart can include a motor that supports and drives the rear wheels. The motor and rear wheels are configured to tilt and rotate relative to the body of the kart. The body of the kart includes a concave space in which the front and rear wheels are positioned so that they are at least partially concealed by the body when viewed from the side of the kart.

A foldable tricycle is provided and has a frame having a first end and a second end, a seat connected to the frame, a front wheel adjacent the first end of the tricycle, and a rear wheel adjacent the second end of the tricycle. A head tube housing is provided adjacent the first end of the main frame, and a fork is provided adjacent the first end of the tricycle. The front wheel is rotatedly secured to the fork. A stem extends from the fork and supports a handlebar, wherein a portion of the head tube housing is slidingly connected to the stem, and wherein the tricycle can be manipulated between a use position and a folded position by sliding a portion of the head tube toward the handlebar.

The invention relates to a transport device (100), more particularly a pram (102), having at least three wheels (116, 118, 120) for moving on a surface (180, 182) and having a handle (110) for a user, wherein at least one wheel of the at least three wheels is designed as a drive wheel (122, 124, 126), which can be driven under electromotive power by means of an associated electrical drive unit (140, 142, 144), in order to permit an at least partial electromotive support to the manual pushing or pulling operation of the transport device by the user on the surface, wherein the transport device is provided with at least one acceleration sensor (172, 174) and a predefined braking torque (F.sub.mot) can be applied periodically to the transport device in pushing or pulling operation by means of the electrical drive unit and wherein a control device (170) assigned to the at least one acceleration sensor is designed to analyse the acceleration values (ax) from the at least one acceleration sensor to detect a presence or absence of the user at the transport device (100) and to regulate the electric drive unit in dependency thereon.
