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.

A child stroller apparatus includes a handle frame having a first side segment fixedly connected with a first coupling part, a front leg frame having a second side segment fixedly connected with a second coupling part, a rear leg frame having a third side segment fixedly connected with a shell, the third side segment being respectively connected pivotally with the first and second coupling parts, a linking member received at least partially inside the shell and respectively connected pivotally with the first and second coupling parts about two different pivot axes, the handle frame and the front leg frame being thereby rotationally linked to each other, and a latch disposed adjacent to the first coupling part, the latch being operable to rotationally lock the handle frame with respect to the rear leg frame so as to lock the infant stroller apparatus in an unfolded state.

A folding shopping cart includes a body frame with a frame connecting base secured at the first end of the body frame. The shopping cart also includes a lower first frame member and an upper second frame member telescopically engaged to define a vertical frame member, wherein a bottom of the lower first frame member is hinged on the frame connecting base. A handlebar is connected with the upper second frame member and front wheels are secured to a second end of the body frame opposite the first end of the body frame. First and second folding rear wheels are respectively secured on opposite sides of the frame connecting base. A button is mechanically linked to a telescopic locking device controlling relative movement between the lower first frame member and the upper second frame member. At least one basket is detachably secured thereto.

A collapsible cart may include a collapsible frame, a foldable shelf, and an interior support column. The collapsible frame includes a first frame portion and a second frame portion. The frame is configured to move between an open configuration and a collapsed configuration by relative translation between the first frame portion and the second frame portion. The foldable shelf extends between the first frame portion and the second frame portion. The foldable shelf is configured to fold to allow the frame to move from the open configuration to the collapsed configuration. The column transversely extends through a column slot defined by the foldable shelf. The cart further includes at least one column brace slidably coupling the frame to the column. The cart further includes at least one shelf brace slidably coupling the foldable shelf to the column.

The present invention discloses a stroller handle lock auxiliary structure disposed in a stroller frame of a stroller. The stroller frame includes a lower frame and a stroller handle pivotally connected on the lower frame. The lower frame includes a first linking rod. The first linking rod is provided with a fitting portion protruding toward an outer side of the lower frame, and the stroller handle is provided with a reversing sliding sleeve matching with the fitting portion. The stroller handle lock auxiliary structure includes a rib that pushes the first linking rod toward the outer side of the lower frame. Compared to the prior art, the stroller handle lock auxiliary structure of the present invention is provided with the rib that pushes the first linking rod outward, and so when the stroller carries a weight, the first linking rod of the stroller frame is prevented from shifting excessively inward, allowing the reversing sliding sleeve to be smoothly fitted with the fitting portion, thereby facilitating locking of the position of the stroller handle and ensuring stability and safety. The present invention further discloses a stroller handle lock auxiliary structure.

A child stroller apparatus includes a first frame portion provided with a first wheel assembly, a second frame portion provided with a second wheel assembly, the second frame portion being assembled with the first frame portion for sliding movement along a lengthwise axis extending from a front to a rear of the child stroller apparatus, and a control mechanism operable to adjust a position of the second frame portion relative to the first frame portion, the control mechanism including an actuator assembled with one of the first and second frame portions, the actuator being operable to drive the second frame portion in sliding movement relative to the first frame portion for modifying a distance between the first and second wheel assemblies.

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.
