A cart assembly that is designed to hold and transport one or more ball hoppers. The ball hoppers have baskets that are supported by legs. The baskets are configured to hold some type of ball, such as a tennis ball or a golf ball. The cart assembly can transport the ball hoppers as they are standing on legs. The cart assembly has a platform that is supported by wheels. The wheels provide the platform with the ability to roll. Receptacles are present on the platform. The receptacles are sized, shaped and positioned to receive the legs of a ball hopper when the ball hopper is placed on the platform. Once a ball hopper is attached to the platform, the ball hopper becomes part of the cart assembly and can roll with the cart assembly from point to point.

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.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers without wheels to large sealable container bins on wheels, to provide large quantities of water or other supplies and cargo. The cases are assembled or in disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking self sealing reciprocating channel and channel engaging members elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.

The present invention relates to a foldable platform truck, including at least one bearing surface supported by at least three wheels; a foldable operating bracket that on one side is rotatable attached to the at least one bearing surface an on the opposite free side has a gripping handle; a lock for securing the operating bracket in at least an unfolded operating locking position; and a control for controlling the operating bracket lock.

A pallet sled includes a base and a plurality of tines extending forward from the base. At least one of the plurality of tines includes a wheel supporting the tine away from the base. A brake assembly is positioned adjacent the wheel to selectively brake the wheel. The brake assembly may include a drum adjacent the wheel. Alternatively, the brake assembly may include a brake shoe selectively directly contacting the wheel to brake the sled.

A moving mechanism configured to be assembled to an object to adjust a movement of the object is provided. The moving mechanism includes a bracket, a first wheel, a brake module, a control module, and a sensing module. The bracket is assembled to the object. The first wheel and the brake module are assembled to the bracket. The control module communicates with and drives the brake module. The sensing module communicates with the brake module, and the sensing module is configured to sense an orientation of the object. The control module adjusts a brake force of the brake module on the first wheel based on the orientation of the object.

A trailer device is provided with pressure washing features and devices. The trailer device is convertible between at least a first and mode of transport, wherein a first mode comprises a towing mode, and a second mode comprises a push or manual operation mode. The device also comprises various on-board features and control systems such that a fully-functional pressure washing unit is provided that is easily transporting between locations.

A system is disclosed which includes a walking assistance robot for assisting a smooth start of a user's action after standing up from a chair. A system according to an aspect of the present disclosure includes a walking assistance robot and an automatic elevation chair that moves a seating surface where a user sits. The automatic elevation chair detects a consciousness level of the user and transmits consciousness level information on the detected consciousness level of the user to the walking assistance robot via the network. The walking assistance robot, including a body and a rotor that moves the walking assistance robot, receives the consciousness level information via the network and controls resistance force to rotation of the rotor based on the received consciousness level information.

A wheel assembly includes: a wheel set unit including a wheel bracket and a wheel; and a brake unit including a brake element disposed between the wheel bracket and the wheel, a threaded member sleeved movably on the brake element, and a screw extending threadably through the threaded member, extending through the brake element so as to prevent movement of the threaded member on the brake element, and pushable downwardly such that the brake unit moves downwardly to press resiliently against the wheel, so as to arrest rotation of the wheel. Only a single tool is needed to be accessed to a lower end of the screw so as to adjust a distance between the brake unit and the wheel.

A service cart and associated apparatus that is suitable for servicing electric vehicles and vehicle batteries. The service cart may comprise a frame having a number of members that may be arranged in a compact configuration. The service cart may comprise a number of support pads that may be adjustably arranged with respect to the frame. The support pads may comprise an overload protection mechanism having a break pin. The service cart may comprise a detachable handle operable to selectively disengage a number of brakes on the cart. The service cart may comprise a tow hitch suitable for detachably coupling an external tow device.
