Containers with one or more tray retention portions and a support stand are described. For example, a container can include: a substantially hollow body including a plurality of body walls extending vertically from a bottom portion; an extension portion rotatably coupled to an outward-facing surface of a body wall among the plurality of body walls, the extension portion configured to rotate to an active position in which the extension portion extends outwardly from the body wall; and a support stand having a proximal end coupled to the outward-facing surface of the body wall and a distal end, the support stand configured to move between at least a stowed position in which the support stand is positioned against or proximate to the outward-facing surface of the body wall and a support position in which the support stand extends outwardly from the body wall.

A pet stroller includes a canopy fabric, a supporting frame, a first longitudinal frame, a second longitudinal frame, a rear wheel frame, and a plurality of wheels. The supporting frame includes a carriage body which has an accommodating cavity and a front opening. The supporting frame includes a main supporting frame, an adjustable supporting frame and a utility frame extended from the main supporting frame to a position corresponding to the front opening of the carriage body for allowing pet's access. When the adjustable supporting frame is in a lying position, the adjustable supporting frame is pivotally moved to substantially align with the main supporting frame for maximizing a volume of the accommodating cavity. When the adjustable supporting frame is in the first inclined position, it is pivotally moved to inclinedly and upwardly extended from the main supporting frame for reducing a size of the accommodating cavity.

The invention relates to a field of a transport driven manually, namely, to baby strollers, and it is intended to allow an alternate use of different variants of a baby cradle or seat which differ in a size and in a weight on a frame thereof. A baby stroller having a frame with adjustable width, the frame consists of front wheel supports hingedly connected between each other, rear wheel supports which are equipped with wheel mounting assemblies, and handle supports, comprising a removable seat or cradle fixed on mounting places, wherein horizontal cross-bars are arranged between the supports of the rear wheels and front wheels. According to the invention, the frame consists of two semi-frames, and the horizontal cross-bars are made adjustable in length and arranged on each of the semi-frames so as to be fixable at least in a first frame adjustment position and at least in a second frame adjustment position.

A portable advertising platform system for store front, street side and indoor promotions. The platform can elevate signs and products above obstacles. Items are fastened at their tops only allowing them to freely swing; wind resistant. This rugged, lightweight platform is made from plastic or aluminum and consists of several joints interconnected by square shaped insert tubes; thumb screw fastening. Tubes can couple together to form longer members. Joints can rotate 90 degrees to create perpendicular branches. The platform consists of a lower cart with several vertical mounts, supporting an upper web with multiple tiers and overhanging arms. The platform can substantially stretch horizontally, vertically and in width providing numerous configurations. The 4 leg levelers telescope multiple feet both horizontally and vertically to level the cart on rough uneven terrain. Leg levelers also act as durable brakes; friction with ground. Detachable large 8 inch wheels swivel for easy maneuvering.

The present invention relates to a removable electric propulsion system (1) for a rolling object. Propulsion system (1) comprises a frame (2) with a driven wheel (3) and at least one non-driven wheel (4). Among these non-driven wheels (4), one at least is an orientable off-centered wheel. System (1) also comprises means for coupling at least one wheel of the rolling object. System (1) also comprises an automatic directional locking device for locking the rotation about a vertical axis of at least one of the orientable off-centered wheels in a predetermined direction.

The invention also relates to a coupled assembly comprising a propulsion system (1) and a rolling object.

The invention further relates to a method for directional and automatic locking of at least one orientable off-centered wheel of a propulsion system.

A multipurpose stand includes a first supporting unit, a second supporting unit and a vertical member. the first supporting unit includes the main body and the roller, the second supporting unit includes the first broad member, the second broad member and the third broad member, The vertical member comprises the first vertical section, the second vertical section and the enlarged end, wherein the second supporting unit is formed by cutting a plate material into the first broad member and the second broad member. The member connected with the third broad member is connected with the connecting member through a single point of the second supporting unit and the first supporting unit, and a vertical member is set between the first broad members of the second supporting unit.

A handcart is provided that includes a frame, wheels, and a motor that drives the rotation of the wheels. The number of wheels is two. The handcart includes a platform coupled to the frame, including a base and a vertical structure. It allows providing a self-propelled handcart with the two wheels and a variable length chassis that is as simple, safe to use, and inexpensive.

A modular extendable trolley (100) including a front module (1) of a loading and unloading floor, a rear module (2) of the loading and unloading floor, a connection module (3) between the front module (1) and the rear module (2), four wheels (4, 40, 4′, 40′) for the movement of the trolley, a drawbar (10) to give direction to the trolley, a tow hook (11) for hooking an additional trolley into a train of trolleys, wherein the front module (1) and the rear module (2) of the loading and unloading floor comprise extensible side portions (1′, 1″, 2′, 2″) and the connection module (3) comprises a longitudinal portion (3′) extendable to vary the dimensions of the trolley (100) itself.

A dolly that is expandable and capable of raising and transporting small or large objects is disclosed. The dolly includes a pair of frames facing each other. The dolly includes a platform positioned over each the frames. The dolly includes a bar receiving section extending from each of the frames. The bar receiving section includes a first hole at its distal end. The dolly includes an elongated bar comprising second holes. The dolly includes pins. The elongated bar inserts through the bar receiving sections such that the second holes align with the first holes in the bar receiving sections and adjust the distance between of the frames. The pins insert through the first holes and the second holes and lock the distance between of the frames. The platforms receive an object such as container, piano, packaging box, etc. for transportation.

Dollies support steered skis of a snowmobile on wheels to enable the snowmobile to be moved along an underlying surface with carbides on the bottom surfaces of the skis free of contact with the underlying surface.
