A folding golf cart including a chassis, a main rod, a handle, a handle-connected seat body, a front wheel, two rear wheels, and two sets of foldable rear wheel frames. The chassis includes two chassis rods, a front-connected seat body, and a rear-connected seat body. The front ends of the two chassis rods are fixed to the front-connected seat body. The rear ends of the two chassis rods are fixed to the rear-connected seat body. The handle is rotationally connected to the handle-connected seat body. The bottom part of the main rod is hinged to the rear-connected seat body. The two rear wheels are respectively connected to the sides of the rear-connected seat body through the foldable rear wheel frames. The middle part of the front-connected seat body is connected to the front wheel through a front wheel retraction and extension device.

A cart for carrying a cut-off saw having a saw blade. The cart includes a frame with upper and lower portions, a wheel arm pivotably coupled to the lower portion about a first axis, and a rear wheel assembly coaxial with the first axis and coupled to the frame and the wheel arm. The cart includes a front wheel coupled to an end of the wheel arm opposite the rear wheel assembly, an adjustment lever pivotably coupled to the upper portion about a second axis, and a link having a first end pivotably coupled to the adjustment lever and spaced from the second axis, and a second end pivotably coupled to the wheel arm between the first axis and the front wheel. Pivoting the adjustment lever about the second axis pivots the wheel arm about the first axis to adjust a vertical position of the front wheel relative to the upper portion.

The present invention relates to an electric propulsion system (1) for a rolling object, comprising a frame (2) with at least one motorized wheel (3), and at least one non-motorized wheel (4), a handlebar (6) and coupling means (5). Coupling means (5) are intended for gripping, orientation and lifting of at least one wheel of the rolling load. The means of orienting the wheel of the rolling object orient the wheel perpendicular to the longitudinal direction (x) of the frame.

The multi-compartment cooler includes two cylindrical, thermally insulated containers stacked on top of each other and mounted on a wheeled platform having a telescoping handle. The lower compartment has a spigot for dispensing hot or cold beverages stored in the compartment, and the upper compartment is adapted for storing a transporting packaged foods, such as salads, sandwiches, cold cuts, etc. The cover of the upper compartment may include a hinged lid incorporating a power bank and inductive charging pad for charging the batteries of cell phones, smart watches, tablets, and other electronic devices. The upper and lower compartments may be releasably latched together during transport. The wheeled platform may have two rear wheels and a front caster, or a rigid front cradle.

A stabilization device for stabilizing an attachment component relative to movements of a basic component which occur outside a permitted plane of movement. The attachment component and the basic component are connected via a stabilization arrangement that includes: a first compensation arrangement for compensating rotational movements of the basic component with respect to an intermediate component, about rotational axes lying in the plane of movement, including a first compensation device which can be actuated actively, a second compensation arrangement for compensating residual linear movements of the intermediate component in a compensation direction, perpendicular to the plane of movement, in relation to the attachment component, having a second compensation device which can be actuated actively, a plurality of inertial sensors assigned to the first and/or second compensation arrangement, and a control device for actuating the compensation devices for movement compensation as a function of sensor data of the inertial sensors.
