A pallet sled includes an upper frame including spaced-apart arms adapted to receive feet of a pallet therebetween. A lower frame supports the upper frame. A plurality of pivotable arms connect the lower frame to the upper frame. A handle is pivotably connected to the lower frame and the upper frame, such that pivoting the handle selectively raises and lowers the upper frame relative to the lower frame.

A drive wheel in which the rotational axial center of a wheel along the vertical direction intersecting the axial center of the axle is arranged shifted in the horizontal direction orthogonal to the axial center of the axle with respect to the axial center of the pivot shaft. When a radius R1 of the wheel, center distance R2 between the rotational axial center and the axial center of the pivot shaft, rotational frequency n1 of the wheel, rotational frequency n2 of the pivot shaft, rotational speed V1 of the wheel, and steering rotational speed V2 of the wheel rolling on a floor surface while turning the pivot shaft satisfy V1=V2, relations of V1=2R1n1, V2=2R2n2, and n1=n2 (R2/R1) are satisfied.

A personal mobility vehicle or scooter includes a least one swivel caster wheel supported at the rear of the scooter. The scooter has a body that includes a deck and a handlebar assembly. The scooter includes at least one front wheel with the deck extending between the at least one front wheel and the at least one swivel wheel. The scooter can also include an angled rear portion supporting a rear swivel caster wheel such that the pivot axis of the swivel wheel is inclined with respect to the top surface of the deck. Embodiments of the scooter also include a swivel braking assembly configured to apply a braking force to the at least one swivel wheel.

A multi-terrain cart, comprising a cart body, two front and two rear non-pivoting wheels, a swivel wheel positioned forwardly or rearwardly to the front and rear non-pivoting wheels, respectively, an actuator for applying a downward force to the swivel wheel which causes the swivel wheel to be set at an operative position and two of the non-pivoting wheels to be raised relative to an underlying ground surface, and means for setting an angle of the swivel wheel relative to a lengthwise extending centerline of the cart body to cause the cart to rotate about a center of rotation that is determined by the set angle of the swivel wheel.

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.

The automated robotic shopping cart is a shopping cart with a controller and locomotion subsystem. The controller may provide shopping assistance to the shopper and may play audio/visual programming to entertain a child riding in the cart. The controller may wirelessly pair with a phone carried by the shopper and may use battery powered motors to propel and steer the cart such that the cart follows the shopper through a store. The battery may be recharged from a solar panel when the cart is outdoors. A GPS receiver in the controller may determine the physical location of the cart and may activate a brake if an attempt is made to remove the cart from the retail property. The invention may further comprise a reading light to illuminate products and a distress button to request assistance.

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 steerable axle includes a housing defining a ball seat therein, a ball member received within the ball seat and defining a cutout portion to receive a portion of a ball bearing therein, an interstitial space defined by a surface of the ball seat and a surface of the ball member, and a ball bearing disposed within the interstitial space and received into the cutout portion of the ball member. The ball bearing moves within the interstitial space when the ball member rotates along the x or y axis, but is restricted from movement along the z axis. Restriction of movement of the ball bearing along the z axis results in a corresponding restriction of movement of the ball member along the z axis.

A transporting apparatus comprising: a standing platform adapted for a user to stand on and wherein the platform has at least two wheels connected to it; a carrying means; a base with at least two drive wheels associated with it and wherein the base is connected to the standing platform; a drive motor which is in communication with the at least two drive wheels and with an accelerating means; and an accelerating means which is in communication with the drive motor; the apparatus is adapted such that when in use a user is able to load items into the carrying means and then stand on the platform and then engage the accelerating means which results in the apparatus moving forward.

A handle assembly for a cart with a power assist function can sense the direction that a user's force is applied, and provide assist power in the corresponding direction, such that the user can easily move the cart. A cart including the handle assembly allows the user to conveniently move the cart.
