According to a first aspect of the present disclosure, there is provided a wheeled transport device featuring at least one castor which has a wheel and a brake system which has a contact member with one opening which is defined by an edge. The contact member is configured to be manipulated between an applied state, where the edge is in contact with the wheel, and a released state where the edge is not in contact with the wheel.

This application relates to a wheel steering angle adjustment device for a vehicle operated by manpower. The device may include a fixed body including a rotation support, a rotation body, a lift member coupled to the rotation support, a locking switch coupled to the lift member, and a plurality of fixing groove portions in the outer peripheral surface of the rotation support. The device may also include a fixing protrusion protruding from the locking switch and configured to be detachably coupled to the fixing groove portions, a rotation range limiting stopper provided on a lower portion of the lift member, and a rotation guide groove portion provided concavely in an upper surface of the rotation body. As the rotation range limiting stopper becomes stuck on an end portion of the rotation guide groove portion, an angle by which the rotation body is rotatable relative to the fixed body is limited.

A mobile surgical robotic cart assembly includes a vertical column supporting a robotic arm thereon, a base, and a plurality of casters each having wheels and each being attached to the base thereby allowing the surgical robotic assembly to move. Each of the plurality of casters has a wheel alignment assembly configured to lock each of the respective wheels in a plurality of orientations.

A method and apparatus for joining at least one daughter cart to a mother cart utilize a coupling system having first and second coupling rails attached to one of the mother and daughter cart frames, and a third coupling rail attached to the other of the mother and daughter cart frames. The coupling rails all extend in a parallel manner to one another in a direction generally perpendicular to a primary transport direction and parallel the underlying surface, when engaged for conveying the daughter cart with the mother cart. The third coupling rail is retained in a channel between the first and second coupling rails, in such a manner that the daughter cart is coupled to and moves with the mother cart as the mother cart is moved in the primary transport direction while the third coupling rail is positioned in the channel between the first and second coupling rails.

A collapsible stroller includes a stroller frame, at least one hinge mechanism, a wheel, and a swivel mechanism. The stroller frame is moveable between a deployed position and a collapsed position. The hinge mechanism allows for movement of the stroller frame between the collapsed position and the deployed position. The swivel mechanism connects the wheel to the stroller frame. The swivel mechanism includes a vertical axle, a cam follower, and a cam. The vertical axle connects with the wheel and is rotatable with respect to the stroller frame about a vertical axis. The cam follower is fixed to the vertical axle. The cam includes a sloped cam surface at least partially surrounding the vertical axle. The sloped cam surface contacts the cam follower to move the cam follower along the sloped cam surface, which results in rotation of the vertical axle about the vertical axis.

A utility cart suited for use in a variety of settings including a biomedical environment that includes a upper tray and a lower tray, configured to store and transport items. The panels making up the utility cart are interlocked using specific grooves and slots to provide rigidity. The utility cart also includes a drawer for storage, and specific coupling elements that allow the cart to be coupled with related devices, such as a second utility cart. Also included are customizable panels easily placed on the sides and back of the utility cart, as well as on a drawer fronts, which are printable using sublimation printing such that the cart may include custom colors, signs, or labels.
