The caster is mounted on a pedestal fixed to the lower end of a column frame on which the whiteboard is mounted.

A vehicle can include a base assembly, a rack assembly, and a processing system. The base assembly can include a platform, a plurality of wheels and a motor for driving at least one of the plurality of wheels. The rack assembly can include a storage shelf connected to the base assembly through a coupling, which includes a bearing assembly enabling the storage shelf to rotate with respect to the platform. The processing system can be configured to communicatively couple with the rack assembly and include one or more processors configured to: determine a location of a target good; cause the storage shelf to move based on the determined location.

A furniture base (10) is disclosed comprising a frame structure (12) and an actuator device (33) that is rotatably supported in the frame structure about a rotational axis. The furniture base (10) further comprises a plurality of wheel units (76, 77, 78, 79) that are movably attached to the frame structure (12) between an upper position and lower position relative to the frame structure (12). The wheel units (76, 77, 78, 79) are connected to the actuator device (33) for movement of the wheel unit (76, 77, 78, 79) between the upper and lower position. The furniture base (10) further comprises a locking mechanism (46) for locking of the wheel units (76, 77, 78, 79) in the lower position of the wheel units (76, 77, 78, 79). The locking mechanism (46) comprises a guide pin (47) that projects out from the actuator device (33) and is attached to the actuator device (33) swingably relative to the actuator device (33). The furniture base (10) further comprises a guide device (53) that guides the movement of the guide pin (47) when the actuator device (33) is rotated for movement of the wheel units (76, 77, 78, 79) between the upper and lower positions of the wheel units (76, 77, 78, 79).

A universal rotating module is provided. The universal rotating module comprises a suspension carrier, a top cover, a globular element, and a plurality of cushion members. The suspension carrier includes a through hole and a plurality of first fixing portions beside the through hole. The top cover includes a plurality of second fixing portions. The globular element is disposed between the suspension carrier and the top cover. A portion of the globular element passes through the through hole. Each of the cushion members is correspondingly connected with the first fixing portion and the second fixing portion.

A coupling mechanism is provided for coupling a supporting element to a frame, and includes a base member and a C-shaped retainer. The frame includes a frame body and a leg member that has a leg body extending downwardly from the frame body to terminate at an enlarged leg end. The base member defines therein a recess for the enlarged leg end therein. The supporting element is coupled to a lower major surface of the base wall. The C-shaped retainer extends to be disposed about the leg body, and is configured to be detachably coupled to a surrounding wall of the base member for retaining the enlarged leg end in the recess.

A laundry treatment apparatus including a plurality of swivel casters. Two of the swivel casters are braked swivel casters. One of the swivel casters other than the braked swivel casters is a vertically adjustable swivel caster. The braked swivel casters restrain translational movement of the laundry treatment apparatus across a floor. The vertically adjustable swivel caster can help fix the position of the laundry treatment apparatus so as to restrain rocking and twisting of the laundry treatment apparatus.

A flip-top table has a tabletop attached to a frame through a pivoting assembly. The tabletop is made from a ballistic-resistant material allowing it to be used as a ballistic shield when it rotates from its horizontal working position to a vertical shielding position. A front modesty panel is also ballistic-resistant and is mounted between the front legs of the frame. A lift speed restrictor is connected between the tabletop and the frame which prevents the user from lifting the tabletop too quickly which could topple the table, and it includes a biasing mechanism that provides a lifting force and helps to hold the tabletop in the shielding position. The table also includes visual indicators that readily indicate to persons around the table that the table can be converted into a ballistic shield. Casters allow one or more tables to be quickly moved and repositioned into a defensive arrangement.

A wheel support assembly for a bottom drawer is disclosed. When the bottom drawer is open, the wheel support assembly may provide support in a deployed position. When the bottom drawer is closed, the wheel support assembly may be retracted in a cavity to be invisible to consumers.

The disclosure relates to a support stand structure with a quick-release wheel mechanism, which includes a stand, a detachable wheeled seat, and multiple fasteners. The stand includes a base. The base has multiple slots and a rear wall. The detachable wheeled seat includes a board and multiple wheels. The board has a front plate disposed above the base and a rear plate projecting over the rear wall. The front plate has multiple tabs extended downwardly and inserted in each slot. Each tab has a through hole. The wheels are mounted on a bottom of the rear plate. The fasteners are installed on a bottom of the base. Each fastener includes a movable pin. Each movable pin is attachable to and detachable from each through hole. Therefore, the support stand has the advantages of stability and saving space with detachable wheels.

The present invention relates to a movable integrated table that can be easily moved to a destination in a state where various items are placed thereon or to allow various items to be placed thereon, and more particularly to a movable integrated table that provides improved decorativeness and is convenient to move such that it can transfer items such as beverages, foods, computers, business items, and business materials to various tables such as various desks or dining tables for the purpose of use, or such that it enables various items to be placed thereon or to be stably transferred in a state where they are placed thereon even within a relatively narrow space in a department store, a shop, an outdoor party hall, a home, a hotel, an office, an indoor/outdoor banquet hall, or a high-class restaurant.
