A working machine may include a first ground-contact part, a driving part configured to drive the first ground-contact part, a clutch mechanism configured to be switched between a transmission state and a non-transmission state, a clutch operation part configured to switch a state of the clutch mechanism, a braking mechanism configured to be switched between a braking state and a non-braking state, and a braking operation part configured to switch a state of the braking mechanism. In a case where the state of the braking mechanism is the braking state, the clutch mechanism may be switched from the transmission state to the non-transmission state by operating the clutch operation part, and in a case where the state of the braking mechanism is the non-braking state, the clutch mechanism may not be switched from the transmission state to the non-transmission state even by operating the clutch operation part.

A wheel for a cart comprises a hollow cylindrical body. The hollow cylindrical body is formed of a stiff material and has a corrugated outer surface and a corrugated inner surface.

A track dolly to mount a camera and accessories thereon is provided. The track dolly includes a steering mechanism to enhance directional control of the dolly when in motion. The track dolly includes a plate, at least one rail coupled to the plate and designed to permit attachment of the camera or accessories thereto, a plurality of wheels rotatably mounted to the plate, a handle rotatably mounted to the plate, and a plurality of linkage members adjustably mounted to the bottom surface of the plate and operably connected to the handle. The linkage members are operably connected to any number of the plurality of wheels. The handle is maneuvered to permit the plurality of linkage members to rotatably adjust any number of the plurality of wheels relative to the plate, thereby adjusting the directional control of the dolly.

A cart that follows a transmission module based on position information of the transmission module and a method for moving the cart are provided. According to an embodiment of the present disclosure, the cart accumulatively stores the position information of the transmission module and generates a moving path based on the position information of the transmission module and moves.

A cart, such as a kitchen cart, has a bottom shelf supported by leg members. The leg members further support a central shelf or basket at a user-desired position along the legs, and a top support. The top support can retain a top work surface thereto. On at least one side of the cart, arms can pivot outward, adjacent the top work surface, to support one or more work surface extension members. Typically, there may be one work surface extension member on each side of the cart, providing the user with additional workspace and providing the option of removal without interfering with the functionality of the cart.

A cart and rack assembly for transporting a planar material includes a rack and a cart. The rack includes a frame coupled to a base. The frame has an upper portion and a lower portion. The upper portion has a first width, and the lower portion has a second width. The cart is configured to reversibly receive the base. The cart includes a guide member configured to guide either of the base or the cart into a predetermined position when the base is received by the cart. The assembly further includes a bracket having a first end and a second end which is configured to selectively secure the planar material to the assembly. The base has a series of apertures configured to accept the first end of the bracket. The second end of the bracket is configured to be selectively coupled with the upper portion of the frame.

A luggage scooter has a middle frame, a front wheel section, a seat section, and a rear wheel section. The front wheel section has a front wheel frame pivotally connected to the middle frame at a front wheel frame joint. The front wheel frame is mounted to a steering joint. The steering joint is mounted on the middle frame. The steering joint provides steering in both a left and right direction. The front wheel frame joint provides the front wheel frame with configurable position between a stowed position and a deployed position. A front wheel is mounted to the front wheel frame at a front wheel support. A rear wheel section has a rear wheel frame pivotally connected to the middle frame at a rear wheel frame joint.

A mobile display cart for storing flooring panels that can be quickly removed and displayed on a floor. The mobile display includes a base supported on a frame with a set of wheels allowing the display to be wheeled to varying locations. The base includes a series of baffles with one or more flooring panels situated within a baffle wherein the panels remain substantially upright when held within the cart. In addition, a cord is connected to one end of the cart and strings through holes within each panel allowing one or more panels to be removed from the basket and displayed on the floor around the cart. However, the cord prevents the panels from being taken away from the display.

An example apparatus includes a base including a first locking surface, a wheel including an axle, and a locking body at the axle of the wheel to rotate with the wheel. The locking body includes a second locking surface to engage the first locking surface of the base to lock the wheel. The apparatus further includes a plate spring that captures the axle of the wheel to allow wheel to rotate. The plate spring urges the second locking surface of the locking body against the first locking surface of the base to lock the wheel. The plate spring is to deflect under application of an external force to separate the second locking surface of the locking body from the first locking surface of the base to allow the wheel to roll.
