A portable cooler includes a first semicylindrical member defining a first aperture in a first side and a second aperture in a second side thereof. A second semicylindrical member is hingedly coupled with the first semicylindrical member. A cradle is removably positioned in the first semicylindrical member. The cradle can rotate with respect to the first semicylindrical member within the space defined by the first semicylindrical member. First and second wheels are rotatably coupled with the first semicylindrical member. First and second axles extend through the wheels and first semicylindrical member and into the cradle. The axles allow independent rotation of the cradle, the first semicylindrical member and the wheels to maintain a substantially horizontal rotational orientation of the cradle with respect to the first semicylindrical member.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A transport assist equipment assists transport of an object. The transport assist equipment includes a plurality of mecanum wheels, a plurality of motors, a first sensor, and a controller. The plurality of mecanum wheels are attached to the object. The plurality of motors are respectively attached to the plurality of mecanum wheels, and configured to respectively drive the plurality of mecanum wheels. The first sensor detects a force applied to the object. The controller is electrically connected to the first sensor and controls the plurality of motors. The controller drives the plurality of mecanum wheels via the motors so as to propel the object along a direction in which the object receives the force, based on a detection signal of the first sensor.

A cart includes a control unit configured to multiply a provisional target front and rear velocity by a correction coefficient thereby setting a target front and rear velocity and multiply a provisional target lateral velocity by the correction coefficient thereby setting a target lateral velocity if the provisional target front and rear velocity is equal to or higher than a front and rear velocity upper limit or if the provisional target lateral velocity is equal to or higher than a lateral velocity upper limit, set the provisional target front and rear velocity to the target front and rear velocity and set the provisional target lateral velocity to the target lateral velocity if the provisional target front and rear velocity is lower than the front and rear velocity upper limit and the provisional target lateral velocity is lower than the lateral velocity upper limit.

A wheel for a cart comprises a hollow cylindrical body. The hollow cylindrical body is formed of a stiff material and has a corrugated outer surface and a corrugated inner surface.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

There is provided a pram frame (200) comprising a first roller attachment point (221) configured to engage with a first roller set (121) and a mechanism (231) configured to engage with the first roller set (121) via the first roller attachment point (221). The mechanism (231) is configured to provide driven steering of the first roller set (121) when a user steers the pram frame (200).

A wheelchair-towable article, such as a luggage article, having a body portion configured for attaching to a wheelchair by a mounting means to dispose the article to the rear of a seat of the wheelchair so as not to be pivotable about a vertical axis with respect to the wheelchair and having a multi-directional roller arrangement for contact with the ground enables a wheelchair user to transport their own luggage, even heavy loads, without assistance and without unbalancing the wheelchair and whilst maintaining full maneuvrability of the wheelchair including tight turns and reversing in tight turns.

A thermally insulated receptacle includes a body, a cover, and a loudspeaker. The body defines a cavity. The cover is operatively coupled to the body and movable relative to the body to selectively cover the cavity. The loudspeaker is pivotably coupled to the body. The receptacle may include a spigot that is configured to be fluidly coupled to a bottle.

Certain exemplary embodiments can provide a dolly comprising a frame, a set of guide rollers, a planetary disc, a set of rollers, and a caster. The frame comprises a plurality of cells. The set of guide rollers is coupled to the frame. The planetary disc constrained within a cell of the plurality of cells via the guide rollers. The set of rollers is coupled to the cell of the plurality of cells. Each of the plurality of rollers contacts a surface of the planetary disc. The set of rollers is constructed to distribute a load placed on the dolly over a surface of the planetary disc, thereby reducing a probability of failure of the dolly. The caster is coupled to the planetary disc.
