A movable coffee capsule storage rack includes a rack body for storage of coffee capsules. A first bracket is fixed to the bottom of the rack body, a first caster is rotatably connected to the first bracket through a first rotating shaft, a second bracket is disposed adjacent to the support leg, a second caster is connected to a second end of the second bracket, and when the second bracket is driven to rotate by the handle to drive the second caster to move down to hold up the support leg, the rack body is entirely supported by the first caster and the second caster and realizes free sliding. With the structure of the present disclosure, the storage rack is allowed to be switched quickly between the fixed state and the moving state through the movement of the second caster, the structure is simple, and the operation is convenient.

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

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.

The present disclosure generally relates to an omni-direction wheel system and methods for controlling the omni-direction wheel system. The omni-direction wheel system includes a plurality of suspension systems that operate independently of one another. Each suspension system may include an electromagnetic steering hub configured to rotate a wheel 360 degrees about a vertical axis based on a polarity of an electromagnetic signal applied to the electromagnetic steering hub. The suspension system may further include an in-wheel motor configured to rotate with the wheel and drive the wheel about a horizontal axis.

A castor wheel support for a towed agricultural implement having a frame positioned parallel to the soil over which the implement is towed. Parallel links interconnect the castor support with the frame. The castor support has a spindle with a longitudinal axis A for supporting a castor mounting structure for pivoting movement. The castor mounting structure supports an axle hub assembly and a wheel. The axis A of the spindle is angled forward 3 degrees to minimize wobbling.

A castor wheel support for a towed agricultural implement. The castor support has a spindle for supporting a castor mounting structure for pivoting movement. The castor mounting structure includes an annular friction element received over the spindle and a plurality of C-shaped shims removable laterally without disassembly of the mounting structure to allow the pressure on the friction element to be set to minimize wobbling.

A caster assembly for a wheelchair comprises a stem having a frame clamp at a first end and a fork clamp at a second end, the frame clamp configured to form a frame joint with at least one rotational degree of freedom with a frame portion of the wheelchair, a tightening of the frame clamp securing the stem to the frame portion, the frame joint having a frame rotational axis. A fork unit has a fork portion and a caster rotatably supported by the fork portion, the fork unit having swivel mechanism, and a joint portion forming a rotational joint with the fork clamp of the stem, a tightening of the fork clamp blocking rotation of the rotational joint, the rotational joint having a fork rotational axis. A vector of the fork rotational axis is normal to a fork rotational plane in which the fork rotates relative to the stem, and further wherein the frame rotational axis is not parallel to the fork rotational plane.

The present invention relates to a castor wheel structure, comprising a wheel part (18) and a castor wheel house (28), on which a transition element can be mounted, such as a spindle structure (1) or a flange structure (2), which again can be mounted on equipment that is to be made mobile, which wheel part (18) is unilaterally suspended and arranged about a substantially horizontal shaft on the castor wheel house (28).
