A movement auxiliary device for a machine stand includes a foot stand. Two sides of the lower end of the foot stand are provided with first and second side seats having vertical rail grooves, respectively. A movable lever, a pivot seat and a lifting roller assembly are provided between the two rail grooves. The foot stand is provided with a support seat. A connecting board having a pedal is pivotally connected between the support seat and the pivot seat, which can be pivoted on the pivot seat. The movable lever is pivotally connected with a pneumatic cylinder to provide a buffering function for the lifting roller assembly and the machine stand. The pedal is controlled for the connecting board and the pivot seat to generate a link pivot, such that the lifting roller assembly is descended to the ground or ascended upward.

A shield 1 for a caster wheel that forms part of a wheeled object, comprising: a perimeter wall 2 configured to extend substantially fully around the caster wheel, and; a connection and supporting means 5, 205 configured to extend from the perimeter wall 2 to connect the shield 1 to the wheeled object; the perimeter wall 2 comprising a resiliently deformable portion 4 that extends substantially fully around the perimeter wall.

A caster wheel adjustment assembly for a wheelchair includes a first mounting member coupled to a wheelchair frame member, a second mounting member coupled to a caster wheel, and an angle adjustment member defining a first side opposite a second side. The first side defines a plurality of first projections, and the second side defines a plurality of second projections. The first plurality of projections includes a different number of projections than the second plurality of projections. The angle adjustment member is configured to interlock with first mounting member and the second mounting member. The first plurality of projections selectively interlock with a third plurality of projections on the first mounting member, and the second plurality of projections selectively interlock with a fourth plurality of projections on the second mounting member.

A movable stand base, of the present invention, comprises: a base case; a wheel housing inserted from the lower part of the base case; a wheel module accommodated in the wheel housing; a rotation plate rotatably coupled to the base case; and a brake ring, which is positioned inside the wheel housing, rotates during rotation of the rotation plate and moves in the vertical direction, makes contact with a wheel of the wheel module during lowering of the brake ring so as to restrict rotation of the wheel, uses the wheel so as to facilitate movement, and can restrict rotation of the wheel so that stability can be increased during mounting.

The present invention provides a structure for assembling a snap-on caster of a draw-bar case. The draw-bar case includes a case body and four caster assemblies. The caster assembly includes a caster and an upper positioning cover. The caster includes a mounting pedestal and a universal wheel. Four sides of the case body are each provided with an installation slot. Several insertion plates are disposed on an inner side surface of the upper positioning cover. The installation slot is penetrated to form a through hole that is disposed corresponding to the insertion plate. The installation pedestal is provided with a buckle plate that is disposed corresponding to the through hole. The buckle plate is penetrated to form an insertion hole. Both sides of one end of the insertion plate are each provided with an inverted buckle. The insertion plate is snap-fitted onto the insertion hole after passing through the through hole and the insertion hole sequentially.

A caster assembly for installation in an electronic equipment enclosure includes a top plate, a forked support member, and an axled wheel. The top plate is attachable to a frame structure of the electronic equipment enclosure and includes a plurality of countersunk recesses. The forked support member extends downward from the top plate, and the axled wheel is supported on the forked support member. The caster assembly is installable in an assembled electronic equipment enclosure by aligning the countersunk recesses of the top plate beneath mating features at an underside of the frame structure such that, once aligned, the weight of the assembled electronic equipment enclosure retains each mating feature of the frame structure within a respective one of the plurality of countersunk recesses in the top plate, thereby retaining the caster assembly in position to support the assembled electronic equipment enclosure.

A furniture rotary system for a piece of furniture is provided. The furniture rotary system is forming a sliding rotary connection between a rotational member and a stationary member wherein said furniture rotary system comprises at least one sliding surface being coated with a lacquer comprising a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction.

The present disclosure relates to a robot cleaner, more particularly, to a robot cleaner that may rotate auxiliary wheels to run over a tilted route or an obstacle, when cannot run over a tilted route or an obstacle because main wheels are not contacting with the floor.
