A convertible stroller assembly may be convertible between a single-occupant configuration and a dual-occupant configuration. The convertible stroller assembly includes a stroller frame being convertible between a laterally contracted configuration and a laterally expanded configuration. The assembly further includes a plurality of rear wheels coupled to the stroller frame. The assembly further includes a front wheel coupled to the stroller frame. The convertible stroller assembly is convertible between (i) a single-occupant configuration in which the stroller frame is in the laterally contracted configuration with the rear wheels being separated by a first spacing, and (ii) a dual-occupant configuration in which the stroller frame is in the laterally expanded configuration with the rear wheels being separated by a second spacing greater than the first spacing.

A tricycle has a forward oriented fork member (20) supported for rotation about a steering axis (14) of the tricycle, a handle bar (50) mounted to the fork member, a cargo unit (24) supported by the fork member, and a pair of transversally spaced linkages (30), wherein each linkage at a proximal end is linked to the fork member and at a distal end supports a respective front wheel (16) of the tricycle. The cargo unit and the linkages are shiftable between respective forward and backward end positions to thereby transform the tricycle to a wheel cart and vice versa.

The disclosure is the only product of its kind that enables users to simply organize food, gear, materials, tools and other items in one easy to access location. The disclosure is uniquely designed with a weatherproof body with protected corners and edges to guarantee impact resistance and durability; yet, provides a lightweight but tough, extendable dolly for managing different tasks. The high performance magnetic sealed pull-out drawer cooler reinvents the use of a standard cooler and includes a zip waterproof pocket on each side along with two cup holders, a bottle opener, and easy to grip handles. The disclosure includes stackable boxes, a folding tray and a telescopic adjustable height handle. The disclosure further includes a pair of retractable wheels configured to support the folding tray hinge and adjust to the width of the plurality of stackable boxes.

The invention provides a stand using two legs which are selectively elongated. Ideally, each leg has two spaced apart wheels allowing the stand to be readily moved. The legs are connected by a scissor member which allows the assembly to be collapsed for storage and easy movement. A receiver for a paper roll is attachable to the top of both legs. A roller, from which paper from the paper roll extends. The legs are manually extended either by hand or in concert using a winch assembly connected to both legs.

A hand truck having a plurality of hingeably engaged sides that is expandable from a closed position dimensioned to fit through a standard doorway, to an open position to form a movable platform having a swing out support frame having an upper end hingedly attached to the rear side of the center frame which is movable between an extended position and a stored position. A corresponding sofa dolly and a platform enclosure is also disclosed.

The present invention relates to a removable electric propulsion system (1) for a rolling object, propulsion system (1) comprising a chassis (2) provided with at least one wheel (3) driven by an electric machine, at least one non-driven wheel (4) and at least one means for coupling electric propulsion system (1) to the rolling object. The coupling means comprises at least one means providing combined and simultaneous gripping and lifting of at least one wheel of the rolling object, and the combined and simultaneous gripping and lifting means comprises a frame (23), at least one arm (24) extendable in a longitudinal direction (x) and connected to frame (23), at least one tilt element (22) and at least one push device (20), one among tilt element (22) and push device (20) being connected to said extendable arm (24) and the other to chassis (2), said push device (20) being capable of driving at least one wheel of the rolling object along said longitudinal direction (x) into said at least one tilt element (22), said tilt element (22) being capable of tilting about an axis of substantially transverse direction (21).

The invention also relates to a coupling method and to a device for coupling a propulsion system to the rolling object.

Disclosed is a cooler assembly that may be used to attach accessories and/or one or more wheel assemblies to an insulated body of a cooler. The insulated body of the cooler being a container body of a container (i.e., the cooler). The cooler assembly may include any one of or a combination of the following components: the container body (i.e., the insulated body of the cooler); the one or more wheel assemblies with or without adjustable axles for mobility; accessories such as an accessory table and an accessory chair; accessory fastener devices for attaching the accessories to the cooler; and wheel assembly fastener devices for attaching the wheel assemblies to the cooler. The accessory fastener devices and the wheel assembly fastener devices are reusable and may be easily inserted and removed from the cooler or the container for mounting on a second cooler or platform.

A dolly includes a first skate, a second skate, and a rod connected to the skates. The first skate is connected to a plurality of wheels and has a receiving region. The second skate is connected to a plurality of wheels and has a receiving region. The second skate includes an outer lateral surface having an aperture. The rod is connected to the first skate and the second skate via the respective receiving regions of the respective skates. The rod is configured to extend through the aperture such that a portion of the rod extends outwardly from the outer lateral surface of the second skate.

The invention relates to a single pushchair that can be converted into a tandem pushchair, comprising: a rolling chassis; a main seat mounted with the ability to move in longitudinal translation with respect to the chassis between a single-occupant position and a dual-occupant position; an auxiliary seat, mounted with the ability to move in longitudinal translation with respect to the chassis between an inactive position retracted underneath the main seat in its single-occupant position, and a deployed active position outside the main seat in its dual-occupant position.

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.
