By providing a plurality of cooperating, foldable panel members in combination with a plurality of foldable wheel assemblies, a unique wagon or cart construction is attained which is capable of being folded into a small, compact area, whenever desired, and then quickly and easily deployed into a fully erected and operational position, which enables virtually any desired object to be easily transported. In addition, in the preferred construction of this invention, an automatically deployed structural supporting member is incorporated into the wagon/cart for providing inherent strength and rigidity to the wagon/cart when fully erected. In this way, heavy objects previously incapable of being transported are capable of being accommodated with ease.

A collapsible stroller frame capable of being either collapsed or expanded with a rod set, wherein a slide sleeve is located at a front supporter of the stroller frame and a foldable supporter is pivotally connected between the front supporter and a rear supporter. A link rod connects the slide sleeve and the foldable supporter, and is pivotally connected between the front and rear supporter. The foldable supporter includes a front folding tube and a rear folding tube, pivotally connected to each other. A user can operate the foldable supporter to shorten the distance between the front and rear folding tubes, by disengaging the slide sleeve from the frame, thereby facilitating assembly and folding of the stroller.

A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

An improved structure of a bicycle for children is disclosed. The bicycle comprises a front and a rear frame and a flexural mechanism is used to connect the front and the rear frame such that the tricycle can be folded. The upper section of the front frame is extended with a foldable handle and the front frame is provided with a rotating shaft. The rotating shaft is connected to a control shaft disposed at the rear frame by means of a cable such that the tricycle can be control the front wheel to move left or right by controlling the left and right movement of the control shaft.

A transportable utility carrier apparatus for coupling to a transport vehicle, including an upper frame, a recessed platform connected to the upper frame, a wheeled base, a lift system interposed between the base and the upper frame for moving the wheeled base relative to the platform between a transport position and a freestanding position, a square hitch tube connected to the upper frame, and a rollered receiver hitch mountable to the transport vehicle. The wheels are spaced from the ground in the transport position. The square hitch tube is receivable within the rollered receiver hitch and the rollered receiver hitch eases insertion of the square hitch tube thereinto to prevent binding on unleveled ground.

This invention provides a structured luggage system that allows for maximum versatility in luggage piece dimensions and using two luggage pieces. Each of the two luggage pieces can be converted from a full-height luggage piece to an approximately half-height piece with relative ease. The lower or main piece includes conventional wheels and a retractable/extendible handle for easy transport. The upper or secondary piece is adapted to stack on and be secured to the extended handle and (in full-height configuration) offer a secondary grip for added stability adjacent to the handle grip. The lower piece includes an inner central septum that can be sealed or opened to selectively define either a two-compartment piece or large, single compartment piece. Each compartment includes easily removable stiffeners in corresponding side pockets. By removing the upper compartment stiffeners, the pocket can be collapsed into a thickened top that includes the septum as the thickened top's inside face. By also removing the bottom set of stiffeners, the bottom compartment can be collapsed, allowing the entire main/lower piece to be compressed for easy storage.

A modular standing frame is described herein. The modular standing frame has a chair module adapted to raise and lower a user between sitting and standing postures without inducing shear between the user and the seat and seat back of the chair module. The chair module may be selectively coupled to one of a glider module adapted to provide walking-type exercise to a standing user, a workstation module that provides a work surface for a sitting or standing user, and a mobility module that allows the standing frame to be moved about by a user much like a wheel chair.

A collapsible support structure has pairs of leg members (17) pivotally joined intermediate their length in crossed fashion by a connection member (18) that is capable of sliding longitudinally with the pivotal joint as the leg members extend in a scissors—like manner to support an object.

A collapsible two wheeled vehicle comprises a substantially rigid main structural frame (10) defining a head section (16), a saddle pillar mount (17) and a bottom bracket (15). A rear wheel sub-frame (22) is pivoted to the frame (10) about the bottom bracket (15), and carriers a rear wheel (23), the sub-frame (22) being arranged for movement between a folded position where the rear wheel lies within the frame, between the head section (16) and the saddle pillar mount (17), and an active position where the sub-frame projects rearwardly beyond the frame. A pedal arrangement (19, 20, 21) is journalled in the bottom bracket (15) and drives the rear wheel (23) through an endless chain (25). A front wheel carrier is journalled to the head section (16) of the frame and has an arm (30) rotatably supporting a front wheel (31), the arm (30) being pivoted to the carrier for movement between a folded position where the front wheel (31) lies adjacent the rear wheel (23) when the sub-frame is in its folded position, and an active position where the arm projects generally downwardly from the carrier. The frame (1) carriers two opposed side panels (50) which are dimensioned so that the folded rear wheel sub-frame, rear wheel, front wheel carrier, folded arm and front wheel all lie substantially wholly within the confines of the side panels, the rear and front wheels lying outside the confines of the side panels when the sub-frame and arm are in their respective active positions.

A collapsible side wheeled walker accommodates a user walking to one side of the walker while holding the walker and supporting at least a portion of the user's weight on the walker. The walker can be collapsed in a tripod-like manner into a compact configuration that is easily transported and stowed.

The invention comprises a trolley with an frame (1) with wheels (10, 11) and at least one handle (5), which is characterised in that the frame (1) comprises: a main supporting rod (2), equipped with the handle (5) at the upper end, and at least one wheel (11) at the lower end; a sub-supporting rod (7), fastened at its upper end to the main supporting rod (2) between the extreme ends of the main supporting rod, and equipped with at least one wheel (10) at the lower end; and wherein the wheels (11) are fastened to the main supporting rod via a first crosspiece (4) and/or where the wheels (10) are fastened to the sub-supporting rod via a second crosspiece (9).

A baby stroller frame with a seat direction changing mechanism comprising a wheeled support frame, a seat support, a handle bar and a releasing mechanism. The wheeled support frame comprises a front leg, a rear leg and wheel sets. The upper portion of the wheeled support frame has a axle hole for pivotally connecting the seat support and allows the seat support rotatably to change its direction. The angle positioning of the seat support is lockable and releaseable by driving a locking member in a locking position. The releasing mechanism is slidably mounted on the handle bar, and shall concomitantly pulls locking member while the handle bar is rotated by a user. While the locking member is pulled to leave the locking position, the seat support will be free to rotate and change its direction.
