The trailer is coupled to the hitch receiver when the wheels are positioned in the stored position. Thus, the vehicle carries the trailer.

A hand trolley includes a trolley main body and a handle assembly. The handle assembly includes a handle, a fastener, and an elastic member. The handle is displaced relative to the trolley main body between a folded position and an unfolded position. The fastener is pivotally connected to the handle. The elastic member is connected with the handle and the fastener to provide an elastic force for the fastener to be located at a predetermined fastening position. When the handle is displaced relative to the trolley main body toward the unfolded position, the fastener is pivoted to engage with an engaging portion of the trolley main body.

A collapsible stroller assembly for combining a car seat and a stroller includes a car seat that has a chair portion and a backrest portion. The car seat is selectively positioned in a vehicle. A plurality of rollers is provided and each of the rollers is pivotally coupled to the car seat. Each of the rollers is selectively positioned in a deployed position to roll along a support surface. Each of the rollers is selectively positioned in a stored position. An audio unit is coupled to the car seat to emit audible sound. The audio unit is selectively placed in electrical communication with an extrinsic electronic device to receive an audio signal.

A hand truck with main wheels and a toe plate also includes a handle assembly that is mounted to the frame of the hand truck so that the handle assembly is able to rotate and slide relative to the truck frame. The hand truck may be arranged in a first upright dolly position in which the handle assembly is generally aligned with the truck frame and a second cart position in which the truck frame is generally horizontal and the handle assembly is extended and rotated so that it is upright and normal relative to the truck frame. A latch assembly mounted to the truck frame is able to releasably receive and secure the handle assembly in the first upright dolly position.

A portable box table that includes a storage body comprising a plurality of sides enclosing a space suitable for storing items therein, and a wheel assembly coupled to the storage body suitable for enabling transportation of the portable box table over a ground surface. A side of the storage body is configured to be detachable from the storage body, wherein the detachable side further includes extendable legs coupled to an underneath surface of the detachable side, wherein the extendable legs are configured to retract in a storage position parallel and adjacent to the underneath surface of the detachable side, and wherein the extendable legs are configured to extend from the storage position to an extended position to support a work surface of the detachable side in a position substantially parallel to the ground surface.

This device relates to devices that can be used to transport equipment, tools and goods and other items from one location to another. The device can haul equipment such as test or analysis equipment. The device has a pocket and compartment for holding a laptop securely during transport. Affixed to the pocket is a folding first shelf for taking notes or working surface. There is a folding second shelf having telescoping holders for securing equipment. The device has wheels that roll smoothly over uneven surfaces. There are collapsing legs that are used to keep the device stable on uneven surfaces. A collapsing base is used to haul equipment, boxes and other large bulky or heavy items. The device is adjustable in the vertical direction to allow the user to adjust the shelf surfaces to a height that is comfortable.

A child transport carrier includes an upper frame member having a forward end and a rear end and a rear frame coupled to the upper frame member. The rear frame includes a lower rear frame member, an upper rear frame member having an upper end fixedly coupled to the rear end of the upper frame member, and a first joint assembly coupling the lower rear frame member and the upper rear frame member. The rear frame is configured to fold between an unfolded in-use position and a folded storage position. The upper frame member and the upper rear frame member are fixed relative to each other. The first joint assembly is disposed longitudinally rearward of the forward end of the upper frame member and longitudinally forward of the rear end of the upper frame member in the unfolded in-use position.

A bearing structure includes a wheel assembly defining a first front wheel assembly and a second rear wheel assembly, the rear wheel assembly including at least two wheels spaced by a first width defining a first position; wheel supports connecting the axes of rotation of the wheels with the bearing structure; a first folding device enabling a first folding causing a reduction in spacing between the two rear wheels to a second width lower than the first width, defining a second position. A connection system, connecting the wheel supports of the first and second assemblies to the first folding device, enables a second folding of the wheels so as to allow a rotation substantially equal to 90 of the wheels in the horizontal plane when the wheels are in the second position.
