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 apparatus and system for facilitating the controlled ascent and descent of stepped or irregular inclines, such as a set or flight of stairs. In an embodiment, the invention comprises an apparatus and system that allows an operator to safely transport a heavy load up or down a flight of stairs. The invention may be utilized with, attached to or incorporated within a transporting carrier, such as a hand truck or hand cart, for transporting heavy cargo up or down stepped or irregular inclines. In an embodiment, the invention allows a wheel to rotate freely in one direction while regulating the rotation of said wheel in the opposite direction such that a braking force in said opposite direction is proportional to the apparent weight and angle of inclination of said carrier. In operation, a gravitationally induced increase in an apparent weight activates the invention's braking system, thereby providing a braking force to the carrier wheel.

The present invention relates generally to a collapsible agile refreshment trolley (CART) that is able to expand and collapse either manually or automatically, to allow passageway of customers in the aisles (e.g. in an airplane, train, ship, bus, or other instance where a narrow region is present and should be circumvented, such as a passenger traveling to a restroom). The CART should be able to be reduced and expanded to allow passageway for emergency (e.g. attending to person having a medical condition after service has begun on the airplane), urgency (e.g. for a passenger in the front of the coach section to go the restroom past the service cart after the service has already begun), or other reasons (e.g. two carts, a drink cart and a food cart, need to pass each other in a narrow passageway, etc.).

In the specification and drawings an accessory cart is described and shown with a base, a housing element that is connected to the base and extends upward from the base, and a platform, which is connected to the housing element with the height of the platform being automatically adjustable.

Provided is a vehicle speed control device with respect to which the speed at which a centrifugal brake operates can be easily changed from the outside without disassembling the device. A brake drum 11 is fixed to a vehicle body 101a. A brake shoe 23 rotates around a rotary shaft 20 of the wheel 101c, and reduces the rotation speed of the wheel 101c as a result of coming into contact with an inner circumferential side face of the brake drum 11. A spring 24 prevents contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c is lower than or equal to a predetermined speed, and permits contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c exceeds the predetermined speed. A position change mechanism 25 is installed within the brake drum 11, and changes the position of an end of the spring 24 on one end side. A transmission mechanism 26 transmits a force that is input by an external operation to the position change mechanism 25 and drives the position change mechanism.

An improved configuration of a mobile-type radiographic image pickup device reliably stops on a flat path without play. More specifically, the prevent invention stops reliably on an inclined path. Where a carriage accelerates regardless of that fact that a deceleration control unit has begun to restrict the movement of the carriage, a brake control unit causes a brake device to operate. According to the present invention, if the carriage accelerates regardless of the fact that a deceleration control unit has begun to restrict the movement of the carriage, the brake device is promptly operated, and prevents concern regardless of the application of an instruction to stop the carriage which is travelling on an incline, and prevents the carriage from running for a long period to time.

A wrap around walking aid is configured to assist a human user in walking. The wrap around walking aid comprising has a first rear lower frame and a first front lower frame mechanically coupled to a first upper frame. A back rest is connected to the first rear lower frame. A second rear lower frame and a second front lower frame are mechanically coupled to a second upper frame. The second rear lower frame is further mechanically coupled to the back rest. At least one first fixed front wheel is mechanically coupled to both front lower frames. At least one first castor rear wheel is mechanically coupled to both rear lower frames. The wheels enable a turn radius while the human user is walking forward.

According to a first aspect of the present disclosure, there is provided a dolly featuring at least one wheel, an auto-engaging brake, and a release mechanism for selectively manipulating the auto-engaging brake from an applied state to a released state. The dolly further includes a tow bar which is connected to the release mechanism for operating the auto-engaging brake between the applied and released state.
