A sensing component may also be included which is carried on the caster for sensing a condition affecting the caster, and generating an output signal in accordance with the sensed condition to the processor.

An electrical brake mechanism for a caster can reliably brake a caster. A switch is mounted on a target to which a caster is attached and outputting an instruction signal to a brake device, a detector is provided on a rotating shaft of the cam and arranged in correspondence with each of positions of a plurality of cam surfaces, a sensor is provided for detecting abutment between each of the cam surfaces and an operation shaft by the detector, a motor is provided for rotating by an input of the switch and for stopping if the sensor detects the position of the predetermined cam surface, and a gear train is provided for transmitting rotation of the motor to the rotating shaft of the cam.

A material vehicle, a traction apparatus and system, a method for controlling the bidirectional traveling of a material vehicle, and a storage medium. A material vehicle (10) comprises a vehicle body (101), an unlocking assembly (102), a plurality of front universal wheels (103) and a plurality of rear universal wheels (104), wherein the plurality of front universal wheels (103) and the plurality of rear universal wheels (104) are all in a locked state; the vehicle body (101) is used for placing a target article; the unlocking assembly (102) is used for releasing the plurality of front universal wheels (103) from the locked state when same are in a horizontal rotation direction, and controlling the material vehicle (10) to travel in a first direction by means of the plurality of front universal wheels (103); and the unlocking assembly (102) is further used for releasing the plurality of rear universal wheels (104) from the locked state when same are in the horizontal rotation direction, and controlling the material vehicle (10) to travel in a second direction by means of the plurality of rear universal wheels (104), the first direction and the second direction being opposite to each other. By means of the unlocking assembly, the plurality of front universal wheels or the plurality of rear universal wheels can be released from the locked state thereof, such that the material vehicle can change the positions of driving wheels, and bidirectional traveling can be realized without needing to turn the material vehicle around.

Systems and methods are disclosed for containers having lever-based actuation of brakes and locks. In one embodiment, an example container may include a first container wall, a second container wall, a third container wall, a fourth container wall, a first wheel, a second wheel, and a wheel lock assembly configured to prevent swiveling of the first wheel. The wheel lock assembly may include a first wheel lock, a first lever configured to actuate the first wheel lock, and a first cable that is coupled to the first wheel lock and the first lever, where the first lever is disposed on the third container wall, and a wheel brake assembly configured to prevent rotation of the second wheel, the wheel brake assembly including a first wheel brake, a second lever configured to actuate the first wheel brake, and a second cable coupled to the first wheel brake and the second lever.

A wheeled childcare device includes: a body frame; a front-wheel caster mechanism and a rear-wheel caster mechanism each including a caster holding member and a caster pivot member and each configured to allow a front wheel or a rear wheel to swivel; a front-wheel caster lock member and a rear-wheel caster lock member each configured to assume a lock position and an unlock position; a front-wheel-side displacement member and a rear-wheel-side displacement member each configured to be displaced between a first position corresponding to the lock position of the caster lock member and a second position corresponding to the unlock position of the caster lock member, according to switching of the position of a push bar; and an operation mechanism provided on the push bar and configured to operate the displacement member to switch the displacement member from the first position to the second position.

A wheeled childcare device includes: a body frame; a caster mechanism including a caster holding member and a caster pivot member and configured to allow a front wheel or a rear wheel to swivel; a caster lock member provided in the caster mechanism and configured to assume a lock position and an unlock position; a displacement member connected to the caster lock member via a connecting member and configured to be displaced between a first position corresponding to the lock position of the caster lock member and a second position corresponding to the unlock position of the caster lock member, according to switching of the position of a push bar; and an operation mechanism provided on the push bar and configured to operate the displacement member to switch the displacement member from the first position to the second position.

A wheeled childcare device includes: a body frame; a caster mechanism including a caster holding member and a caster pivot member and configured to allow a front wheel or a rear wheel to swivel; a caster lock member provided in the caster mechanism and configured to assume a lock position and an unlock position; a displacement member configured to be displaced between a first position corresponding to the lock position of the caster lock member and a second position corresponding to the unlock position of the caster lock member; a first biasing member configured to bias the displacement member toward the second position; and a drive member provided on the push bar and configured to be switched between a first state and a second state.

A wheeled childcare device includes: a body frame; a caster mechanism including a caster holding member and a caster pivot member and configured to allow a front wheel or a rear wheel to swivel; a caster lock member configured to assume a lock position and an unlock position; a first biasing member configured to bias the caster lock member toward the lock position; and a moving member provided in the caster holding member and movable between a first position and a second position. The first position is a position in which the caster lock member is moved to the lock position, and the second position is a position in which the caster lock member is moved to the unlock position.

A self-positioning swivel caster may include a swivel mechanism that defines a home position of the caster. The swivel mechanism may include a compression spring, an upper cam, and a lower cam that is coupled to the caster wheel, in which the upper and lower cams include mating surfaces that define the home position. A bias force applied by the compression spring to the upper cam may cause rotation of the lower cam to the home position. When coupled to mobile containers, self-positioning swivel casters in home positions may increase clearance under the mobile containers for robotic drive units or other material handling equipment used to move the mobile containers, and the self-positioning swivel casters in home positions may also prevent drift or rolling of the mobile containers away from current locations.

A stroller handlebar actuator is provided. The handlebar actuator is provided at a handlebar of the stroller and includes cables that are attached to the handlebar actuator at one end and rear wheels of the stroller at another end. The handlebar actuator includes a protruding tab that a user to able to press using one or both thumbs without needing to remove their hands from the outer ends of the handlebar. By pressing the tab, a rotational force is exerted on the handlebar actuator, causing the handlebar actuator to rotate relative to the handlebar. This rotation causes the cables to pull inwards towards the handlebar actuator, thereby unlocking mechanisms provided at the rear wheels. The unlocking of the mechanisms causes the rear wheels to be able to freely rotate about a vertical axis. When the force is removed from the handlebar actuator, the handlebar actuator rotates back to its natural resting position and the cables return back to their original positions, locking the rear wheels.
