A foldable rollable golf bag trolley comprising a push handle assembly, a front leg assembly a left rear leg assembly, a right rear leg assembly, a folding mechanism having two universal joint sub-assemblies, a series of hubs and ramp discs, wherein said components of the folding mechanism are aligned about a central axis of a main pivot shaft in a first position. The folding mechanism further comprising a plurality of locking gears and springs wherein the two universal joint sub-assemblies and a left and right ramp disc cause a left rear hub and a right rear hub to move in two dimensions when the folding mechanism is engaged in a second position.

A foldable cart has a stabilizing handle device, which includes a connecting seat. The connecting seat has a connecting groove and two connecting rods of the foldable frame of the foldable cart are pivotally connected to the connecting seat in the connecting groove. A pulling rod mechanism is pivotally connected with the connecting seat. The connecting seat has a fixing strut that extends between the connecting seat and the foldable frame. When the cart frame is folded, the two connecting rods rotate about their pivot connections with the connecting seat, so that the two connecting rods approach each other. The connecting seat is fixedly connected to the fixing strut and a pivot point on the front side of the foldable frame so that an angle between the two remains fixed, which prevents the pulling rod mechanism from toppling left and right.

A method for controlling an electric hand truck includes determining whether user manipulation is present due to a user input on the electric hand truck; and, if there is no user manipulation, then braking an electric motor that drives the wheels of the electric moving vehicle in a softlock manner in which, instead of power being applied to the electric motor, electrodes of the electric motor are short-circuited.

A foldable beach wagon with steerable front wheels is disclosed. The wagon has a frame having a first end assembly, an opposing second end assembly and a floor assembly connected between the first end assembly and the second end assembly. A steering link is pivotally connected to the wagon frame adjacent the first end assembly, and a handle is pivotally connected to the steering link. When the steering link is pivoted by the handle a tie rod moves laterally to pivot the front wheels for turning the wagon. A hanger assembly is connected to the wagon frame adjacent the second end assembly. The hangar assembly is adapted to receive one or more chairs. Fenders are provided over the rear wheels to block engagement of the chairs with the rear wheels of the wagon.

A cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to control electric power supply to the motor; a motor control device configured to control the motor via the motor drive circuit; a switching element arranged on an electric power supply path to the motor drive circuit; a switch circuit arranged separately from the motor control device and configured to switch the switching element between a conduction state and a non-conduction state; and an operation member arranged on the cart and configured to be operated by a user. The cart may operate in a manual mode in which the motor is driven when the operation member is on and the motor is stopped when the operation member is off, and in an automatic mode in which the motor is driven regardless of whether the operation member is on or off.

A cart includes a carriage, a right front wheel, a left front wheel, a right rear wheel and a left rear wheel, and a suspension mechanism. The suspension mechanism includes a steering shaft, a link member, a tie rod, a holding member, and a buffer member. When the cart is viewed from behind, a lower space is defined under the carriage. The lower space has a width of ⅓ or more of a distance between a left side surface of the right front wheel and a right side surface of the left front wheel between the right front wheel and the left, front wheel. The lower space between the right rear wheel and the left rear wheel has the width of ⅓ or more of the distance between a left side surface of the right rear wheel and a right side surface of the left rear wheel.

The cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to drive the motor; a control device configured to control the motor via the motor drive circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed; and an operation member arranged on the cart and configured to receive an operation by a user. The cart may be configured to operate in a manual mode where the motor is driven when the operation member is on and the motor is stopped when the operation member is off, and in an automatic mode were the motor is driven regardless of whether the operation member is on or off. The upper limit travelling speed in the automatic mode may be set lower than the upper limit travelling speed in the manual mode.

A cart may include: a carriage; a wheel supported by the carriage and touching ground; a holding member rotatably supported by the carriage about a steering axis and rotatably supporting the wheel about a rotation axis; a steering handle to be gripped by a user; an input sensor configured to detect an operation on the steering handle by the user; a steering motor configured to be actuated in response to the operation by the user detected by the input sensor; and a transmission mechanism connecting the steering motor and the holding member and configured to rotate the holding member about the steering axis in response to actuation of the steering motor. The steering handle and the transmission mechanism may be mechanically separated, and the transmission mechanism may include a torque limiter interposed between the steering motor and the holding member.

A surgical robot a robotic device and a cart. The cart is coupled to the robotic device and includes a steering assembly. The steering assembly includes wheels and is configured such that the wheels allow the cart to roll in a linear direction when a first mode is selected and the wheels allow the cart to roll in a rotational direction when a second mode is selected.

Provided are a handle assembly for a cart having a power assist function, and a cart in which the power assist function enables a user to easily move the cart by detecting a direction, in which a force of the user is applied, to assist power in the relevant direction. According to the handle assembly and the cart, the user can easily move the cart by detecting the direction, in which the force of the user is applied, to provide auxiliary power (a power assist function) in the relevant direction, thereby improving convenience of the user.
