A modular cabinet system including a cabinet shell configured with an open front space, a cabinet insert configured to be selectively installed in, and removed from, the cabinet shell by being passed through the open front space, a pair of first slide members respectively provided to each inner side surface of the cabinet shell, and a pair of second slide members respectively provided to each outer side surfaces provided proximate each side of the cabinet insert, wherein the respective first slide members are configured to interact with the corresponding second slide members to guide the cabinet insert into, and out of, the cabinet shell.

A multidirectional wheel assembly for facilitating a cart to be moved in any direction at any time. The assembly includes a cup that is coupled to a leg of a cart. A sphere is rotatably positioned in the cup and the sphere rolls along a support surface. The sphere is rotatable in a selectable direction in the cup to facilitate the cart to be urged in the selectable direction.

A repel assembly and method includes an engagement surface having an adhesive plane for securing to an object, a plurality of attachment spikes extending from the engagement surface at an angle transverse to the adhesive plane and a transport surface for supporting a fixture coupled to the plurality of attachment spikes, the fixture being positioned between the engagement surface and the transport surface. The repel assembly further includes an annular ring having an upper and lower ring coupled to the repel assembly, the lower ring having first and second ends spaced by a wiper body such that the annular ring repels debris from contacting and/or collecting on the transport surface.

A portable wheelchair is collapsible for ease of development, handling and transport, while also providing a front steer configuration and a rear steer configuration.

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.

An article movement system includes an article and at least one ball wheel. The article has first and second article surfaces meeting at a first article edge. The ball wheel is located along the first article edge and includes a ball, a bearing arrangement and a shell. The ball engages a surface underlying the article, the bearing arrangement supports the ball for omni-directional rotational movement, and the shell is located along the first article edge and contains the ball and the bearing arrangement. The shell defines a non-circular ball opening through which a portion of the ball extends to contact the underlying surface. The article, the bearing arrangement and the shell are configured such that the ball wheel is able to support the article for omni-directional rolling motion over the underlying surface with either of the first and article surfaces parallel thereto, and at any orientation therebetween.

A person support apparatus includes a base frame with a plurality of caster wheel assemblies, each of the caster wheel assemblies including a caster brake actuator movable between a total braking position and a non-braking position. A linkage system is coupled to the caster brake actuators for controlling the caster brake actuators and is operable to move the caster brake actuators between their total braking positions and their non-braking positions. The linkage system is configured to compensate for tolerances in the linkage system wherein the linkage system can control the caster brake actuators to simultaneously move between their total braking positions and their non-braking positions.

A piece of furniture suitable to rest on a contact surface and including a main structure defining a lower surface facing the contact surface; rolling elements, each including a sphere rolling on the contact surface; and an anchoring body for anchoring the rolling elements to the main structure.

A speed limited wheel includes a wheel main body defining a cavity, a urethane wheel outer overmolded to the cavity, a brake hub and a plurality of brake elements. The brake hub is disposed in the cavity and includes a cylindrical flange. The wheel main body is rotatable relative to the brake hub about a wheel rotational axis. The plurality of brake elements is disposed in the cavity and is circumferentially surrounded by the cylindrical flange of the brake hub. Each brake element is pivotally mounted to the wheel main body for pivoting between a first position spaced apart from a cylindrical flange of the brake hub and a second position engaging the cylindrical flange of the brake hub for generating friction to reduce a rotational speed of the wheel. The speed limited wheel may be a caster.

A robot cleaner includes: a body having a suction port; a plurality of wheels for movement of the body; and a plurality of driving devices configured to drive the plurality of wheels, respectively, wherein each of the plurality of wheels includes an inner wheel and an outer wheel having a thickness that is larger than a thickness of the inner wheel, and each of the inner wheel and the outer wheel includes a plurality of slits.
