A seat includes a seat plate, a first backrest support member, a second backrest support member, a third backrest support member, a first sliding sleeve and a second sliding sleeve. The second backrest support member is telescopically connected to the first backrest support member. The third backrest support member is telescopically connected to the second backrest support member and pivotally connected to the seat plate. The first sliding sleeve is disposed on the first backrest support member. The second sliding sleeve is disposed on the second backrest support member. The first backrest support member, the second backrest support member and the third backrest support member are able to slide with respect to each other to be folded or unfolded. The first sliding sleeve slides as the first backrest support member slides, and the second sliding sleeve slides as the second backrest support member slides.

A stroller includes a frame, a sliding member and a seat fixing base. The frame includes a front linkage rod and a transverse rod. The transverse rod is disposed with respect to the front linkage rod. The sliding member is rotatably connected between the transverse rod and the front linkage rod. The seat fixing base is rotatably connected to the transverse rod or the front linkage rod and slidably connected to the sliding member. When the frame is folded, the front linkage rod and the transverse rod move away from each other, such that the seat fixing base slides with respect to the sliding member.

A dolly assembly includes a parent dolly including a support frame that defines a truck-receiving volume. A child dolly includes a support frame that is sized to be received within the truck-receiving volume. The child dolly includes a child dolly carousel.

A baseboard dispensing assembly includes a pair of plates including an upper plate and a lower plate. The upper plate is positioned on and attached to the lower plate. The upper and lower plates are rotatable with respect to each other. The upper plate has an upper surface and the lower plate has a lower surface. A securing member is attached to the upper surface and is configured to restrict the coil of the flexible baseboard from sliding off of the upper surface. The upper plate receives a coil of flexible baseboard such that the coil is uncoiled while the securing member retains the coil on the upper plate.

A cart assembly includes a base with wheels, a shelf support structure orthogonally arranged with respect to the base, one or more shelves supported by the support structure, and a swivel mechanism. The swivel mechanism is coupled to the base and the shelf support structure to provide an axis of rotation, such that the shelf support structure and the shelf or shelves are selectively rotatable with respect to the axis. The swivel mechanism may include a race that defines a socket on a circumference of the race. A pin is selectively engageable with the socket to prevent rotation of the race and the support structure. The shelf may include a thermoformed plastic tray, or three shelves arranged at three different levels of the shelf support structure. Some of the shelves may fold against and secure to the shelf support structure.

A dish cart includes a top with a slot for receiving a lift arm that may be lifted up through the slot to raise or lower dishes. Lobe openings emanating from the slot receive lobes of a lift paddle secured to the lift arm. The cart may define a gap below the top for permitting insertion of the lift paddle and the lift arm. The cart may be adjusted to receive differently sized dishes by means of rails of different sizes or adjustable vanes. A dish drop station includes the lift arm and lift paddle and a lift mechanism for raising and lower the lift arm. The dish drop station may include a cart present sensor and include a lock for retaining the cart. The controller may be programmed to the lower the lift arm to an unlock position that disengages the cart lock.

A shopping cart assembly includes a shopping cart for carrying purchased items in a retail environment. The shopping cart has a cage and a bottom shelf.
