There is provided a shopping cart comprising a shopping cart basket with a vertically movable bottom wall. The vertical movement of the bottom wall is controlled by two pairs of springs. The first pair of springs has a first maximum load capacity, while the second pair of springs has a second maximum load capacity that is greater than the load capacity of the first pair of springs. The first pair of springs is connected to either the fore or aft corners of the bottom wall. The second pair of springs is connected to the side edges of the bottom wall. Low-friction, non-binding rollers are attached to the upper end of each spring and engage respective guide posts. Preferably, to avoid trapping items (or fingers) in the side walls of the shopping cart basket as the bottom wall lowers, the side walls of the shopping cart are initially collapsed and subsequently expand as the bottom wall lowers. In addition, the shopping cart preferably has a hand brake that prevents movement of the shopping cart unless held open by a user.

A new storage apparatus is provided which includes a rectangular box-like containment vessel in which a false movable floor is provided over the bottom floor. A dunnage bag or other actuator is provided to selectively raise and lower the false floor to facilitate self-evaluation and discharge of dry flowable material through a discharge port. The false floor structure may be removed to provide for versatility and different storage options. For example, the containment vessel can be left empty to provide for storage of other objects through openable doors or a pillow tank may be installed within the containment vessel to provide for liquid holding capabilities.

A ramp assembly is suitable for use with a vehicle having a floor. The ramp assembly includes a ramp rotatably coupled within the vehicle, and a moving floor having an inboard panel and an outboard panel. The outboard panel has an outboard end hingedly coupled to the inboard end of the ramp to define an outboard hinge line that moves between a raised position when the ramp is in a stowed position and a lowered position when the ramp is in a deployed position. An outboard end of the inboard panel is hingedly coupled to an inboard end of the outboard panel. A reciprocating mechanism reciprocates an inboard end of the inboard panel between a lowered position and a raised position.

A robotic gantry system, end-effector for a robotic gantry system and method of transporting products using a robotic gantry system is provided. The end-effector includes a movable floor that can be positioned below picked products to prevent products from being dropped during transport. The movable floor also permits selecting individual rows of products from a given layer of products of a product stack. The end-effector may include a vacuum assembly for vacuum adhering to the products. The method permits selection of varying portions of a stack of products with the end-effector and protecting the selected portions of products using the movable floor.

The automobile wind tunnel test system lays out the moving belt ground effect simulation system (1) and the wind tunnel balance (3) on the lower part ofthe wind tunnel test section of an automobile, wherein the moving belt ground effect simulation system (1) is arranged below the tested automobile (4), and the wind tunnel balance (3) is connected with the tested automobile (4) through an automobile body supporting device (2).

A mobile apparatus, particularly an autonomously mobile floor cleaning device, has a chassis and wheels, wherein at least one wheel is driven, and the driven wheel is connected to the chassis via a suspension element that supports the wheel and is movable relative to the chassis. In order to create an alternative mobile apparatus for negotiating an obstacle, the wheel for support on a subsurface over which the mobile apparatus can travel is influenced by a spring exerting a spring force and can be retracted and extended relative to the chassis with the aid of the suspension element, wherein the spring force is adjustable independently of an increase or decrease in the spring force caused by such extension or retraction, and in particular may be increased as the wheel is extended farther.

An autonomous moving floor-treating robot and a control method thereof for edge-following floor-treating are provided. The control method includes the following steps: the floor-treating robot collides with an obstacle and is deflected toward the direction away from the obstacle by a basic angle after the collision, measures an initial signal strength value by a side-looking sensor after the deflection, and then moves on and treats the floor; a real-time signal strength value is acquired by said side-looking sensor alter the robot runs for a predetermined time; the difference value between said two signal strength values is compared, and whether the difference value is in a predetermined range is judged, if yes, the robot keeps moving and treating the floor, if not, the robot is driven to be deflected by an adjusting angle and acquires the current real-time signal strength value; the difference value between said current and the last real-time signal strength values is compared, and whether the difference value is in a predetermined range is judged, if yes, the robot keeps moving and treating the floor, if not, the steps of deflection, comparing and so on are implemented. The present invention is unaffected by the media of the obstacle, and can effectively treat the edge region of the ti obstacle.

A rectangular bin for storing and transporting books at a sorting station in a library has a base on wheels with four side walls and a horizontal floor panel movable vertically within the bin. An optical sensor is mounted adjacent the upper rim and is controlled by a control unit such that during a filling mode of the bin, the detection of a book interrupting the beam lowers the floor panel so as to allow further filling of the bin up to the height of the optical sensor and during an unloading mode the operation is reversed. A battery pack is located in a cavity in the front wall and when being charged at a loading station the control unit automatically operates the filling mode and when disconnected the control unit automatically operates the unloading mode. The actuator has two pairs of levers and an electrically actuated screw for moving the floor panel with a lower end of the screw housed in a bottom housing hung below the base.

A floor portion separates a weighing chamber encircled by a windshield case and accommodating a weighing pan, and a balance body accommodating a load detecting section, an incorporated weight, etc. A plurality of vents is provided through the floor portion. A movable floor is arranged to be able to move back and forth on supporting members. A plurality of vents is provided through the movable floor on the rear side of the floor portion so that number and center position of the vents of the movable floor is the same as the vents of the floor portion. When a temperature difference between the temperatures within the weighing chamber and within the balance body is large, the movable floor is moved to permit airflow between the weighing chamber and the balance body.

A moving floor system that includes a moving work surface to move work products from an upstream end to a downstream end. The moving work surface is formed from a plurality of individual carts joined to each other. The stack of carts is moved along upper support rails located at an upper level. When each individual cart reaches the downstream end, a downstream lift conveyor moves the individual cart from the upper level to a lower level. When at the lower level, each individual cart is returned from the downstream end to the upstream end. When each individual cart reaches the upstream end, an upstream lift conveyor returns the individual carts from the lower level to the upper level. An upper drive mechanism provides the motive force to move the stack of carts along the upper level at the working speed.
