The present disclosure relates to a double stroller, with a frame thereof including three side supports and two transverse supports. Each two adjacent side supports are connected to each other via one transverse support. Each transverse support includes at least one connecting rod assembly, and each connecting rod assembly includes an outer connecting rod fixedly connected with the side support on a left or right side and an inner connecting rod fixedly connected with the side support in the middle. The outer connecting rod is connected to the inner connecting rod in a horizontally rotatable manner. The outer connecting rods and inner connecting rods connected in a horizontally rotatable manner to enable the side supports on two sides to close together as the outer connecting, rods are turned transversely and folded, and thus, after being folded, the space occupied by the double stroller in the left-right direction is lessened.

An articulating wagon frame has an open position and a closed position. The frame has eight corner joints, namely four upper corner joints and four lower corner joints. The four upper corner joints include a right front upper joint, a left front upper joint, a right rear upper joint, and a left rear upper joint. The four lower corner joints include a right front lower joint, a left front lower joint, the right rear lower joint, and a left rear lower joint. Four linear joints include a right middle upper joint, a left middle upper joint, a left middle lower joint, and a right middle lower joint. Six vertical supports include a right front vertical support, a left front vertical support, a right middle vertical support, a left middle vertical support, a right rear vertical support, and a left rear vertical support.

A collapsible seat assembly is mounted on a frame of a stroller, and includes a joint member, a backrest support member, a leg support member and a locking mechanism. Each of a pivot portion of the backrest support member and a pivot portion of the leg support member is pivotably mounted on the joint member. The locking mechanism is disposed between the pivot portions to lock or unlock the backrest and leg support members. The locking mechanism is configured to be actuated to move from a locking position to an unlocking position by the operation of the frame of the stroller from an unfolded state to a folded state. A stroller having the collapsible seat assembly is also disclosed.

Embodiments of the present disclosure may include a collapsible cart configured to transition from a closed condition where it may be folded up to an open condition where it may be expanded for use, the collapsible cart including a rigid frame forming a compartment, the rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall, the right sidewall and the left sidewall may be configured to fold inwardly in the closed condition. In some embodiments, the right sidewall including a first right panel rotatably coupled to a second right panel. In some embodiments, a retractable handle mechanism is disposed at, within or adjacent the back wall. The retractable handle mechanism includes a hand grip attached to a telescoping assembly. The telescoping assembly is pivotably coupled at a proximal end to the bottom of the rear wall.

The invention provides a luggage apparatus (10, 110) capable of being used in normal mode and alternately in child carrying mode. Luggage apparatus (10, 110) has a top (12, 112) a bottom (14, 114), a front (16, 116), a rear (18, 118) and opposing sides (20, 120) and (22, 122). The dimension between the front (16, 116) and the rear (18, 118) is longer than the dimension between the opposing sides (20, 120) and (22, 122). A first wheel means (24, 124) is located in the vicinity of the front (16, 116). The first wheel means (24, 124) is used to wheel luggage apparatus (10, 110) in normal mode. A second wheel means (28, 128) is located in the vicinity of the rear (18, 118) and, in conjunction with the first wheel means (24, 124), can be used to wheel the luggage apparatus (10, 110) in child carrying mode. A child seat (44, 144) is foldable within the luggage apparatus (10, 110) in normal mode and unfoldable in child carrying mode to be positioned on or above the top (12, 112) of the luggage apparatus (10, 110). In child carrying mode, the longer dimension is substantially parallel to the ground supporting the luggage apparatus (10, 110) and the unfolded child seat (44, 144) is positioned so that the centre of gravity of the child seat (44, 144) and any child thereon is substantially between the front (16, 116) and the rear (18, 118).

A multi-function mobility device may comprise a lower chassis shell and an upper occupant shell connected by a quick release pivot joint that provides occupant accommodation that is secure and comfortable. In addition, the structural architecture is designed to allow safe adaptations to the axle configuration. Through flexible suspension arm mounting the suspension-hub-wheel/tire assembly can be quickly assembled/disassembled to provide alternative usage axle layouts. An ergonomic handle assembly may be coupled with the structure for pushing, pulling, towing, carrying, etc. When disassembled, the multi-function stroller can be folded into a compact storage mode. Thus, non-compromised performance, versatility, and usage functionality can be readily achieved and accomplished in a safe manner.

An appliance-support system in accordance with the present disclosure includes a truss and a rolling support coupled to the truss. The truss is adapted to support an appliance, such as a light, and in combination with other trusses forms a scaffolding for use above an event stage, for example. The system includes collapsible aspects for ease of storage and stacking.
