A modular platform system includes a plurality of tiles, legs, beams, and brackets. Peripheries of the tiles and top surfaces of the beams are configured so that the tiles can snap on to the beams, allowing for easy creation of a platform. The beams, legs, and brackets are all configured so that the beams and legs are easily connected together for platform system creation.

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.

The present invention is generally a load-bearing assembly that may be expanded so as to increase a surface area on which to support different sized loads. The load-bearing assembly may be constructed with multiple T-shaped frames or housings that register with each other forming a unique H-shaped frame design. The two T-shaped housings register with each other in a manner that facilitates the adjustment of the width of the load-bearing assembly. Extensions enclosed within each housing and extendable at terminal ends of each T-shaped housing extend outwardly from their respective terminal ends to adjust a length of the load-bearing assembly. The load-bearing assembly may be constructed of a light, sturdy metal alloy that is lightweight. Applications include moving inventory inside warehouses or moving furniture or appliances from one location to another.

A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.

A reusable handling device is specially designed for transporting components of a checkout station to a location within the store where the checkout station is installed. The handling device includes casters and is designed to removably mount to a checkout station component (e.g., bagger) having adjustable feet when there is a need to move or transport the checkout station component (e.g., during installation). Generally, the handling device is configured to extend between and engage two of the adjustable feet of the checkout station component. Two or more handling devices can be mounted to the checkout station component to move the checkout station component during installation and can be removed when finished. After the installation is complete, the handling devices can be returned to the manufacturer or supplier of the checkout station component for use in another installation.

A foldable shopping cart is disclosed herein. The cart includes a folding frame that supports a fabric container in a basket-like configuration. Additionally, the cart frame includes four wheels of which, the two front wheels are swiveling castor-type wheels and the two rear wheels are fixed and include a braking system. The braking system consists of a friction rod that presses against the wheel via a spring which is connected to a trigger-like mechanism mounted to a foldable bar located between the rear wheels. The cart includes two posts that extend diagonally upward and proximally are vertically adjustable.

A method of facilitating production of a structure at a construction site, the method including the steps of a) obtaining a mobile apparatus having: a frame; first and second wheels and a steerable third wheel spaced in a fore and aft direction from the first and second wheels and laterally between the first and second wheels; and a platform on the frame defining a first upwardly facing surface that is spaced at least 20″ above the subjacent surface; b) placing at least one building component in a transporting position on the first upwardly facing surface; c) advancing the mobile apparatus from the first location to a second location at or adjacent the construction site; and d) separating the at least one building component from the transporting position at the second location.

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 trolley for medical equipment includes a base mounted on a plurality of wheels. A brake device including at least one deformable brake pad is located beneath the trolley base. A release mechanism is provided to move the brake pad between a raised position in which it is spaced above a floor surface on which the trolley wheels rest, and a lowered position in which the brake pad is pressed against the floor surface under the weight of the brake device to a exert a braking force on the trolley.
