The invention further relates to a cleaning system with two or more cleaning carts and a connection device.

The invention relates to a cleaning system comprising a hand-guided cleaning cart which comprises rollers and is movable over a supporting surface, for transporting and storing cleaning utensils for manual cleaning, wherein the cleaning system comprises at least one receiving device arranged at the cleaning cart and two or more different functional devices for operation and/or use of the at least one cleaning cart, wherein the functional devices are selectively connectable to the at least one receiving device, and wherein the at least one receiving device and the functional devices comprise cooperating connecting elements.

A modular extendable trolley (100) including a front module (1) of a loading and unloading floor, a rear module (2) of the loading and unloading floor, a connection module (3) between the front module (1) and the rear module (2), four wheels (4, 40, 4′, 40′) for the movement of the trolley, a drawbar (10) to give direction to the trolley, a tow hook (11) for hooking an additional trolley into a train of trolleys, wherein the front module (1) and the rear module (2) of the loading and unloading floor comprise extensible side portions (1′, 1″, 2′, 2″) and the connection module (3) comprises a longitudinal portion (3′) extendable to vary the dimensions of the trolley (100) itself.

A human-propellable vehicle is described and comprises a chassis and a roller assembly mounted at or towards the rear of the chassis. The roller assembly is positioned to engage with a wheel of a second vehicle to permit the second vehicle to push the human-propellable vehicle.

A transportation rack includes a base frame configured for resting on a surface and including an upper open side and an open front side. The transportation rack further includes an extension frame defining an open front side and being slideably received through the open upper side of the base frame. An actuator is coupled between the base frame and the extension frame and is operable to move the extension frame in an extending direction outwardly from the base frame through the open upper side and a collapsing direction inwardly to the base frame through the open upper side. The transportation rack further includes a compartment unit supported by the extension frame and having a collapsing portion therealong that accommodates the extending and collapsing of the extension frame with respect to the base frame.

According to a first aspect of the present disclosure, there is provided a dolly featuring at least one wheel, an auto-engaging brake, and a release mechanism for selectively manipulating the auto-engaging brake from an applied state to a released state. The dolly further includes a tow bar which is connected to the release mechanism for operating the auto-engaging brake between the applied and released state.

A motorized vehicle includes a front part equipped with at least one steering skid intended to be steered by a handlebar, a rear part including a chassis rigidly attached to a tracked propulsion means and driven by a transmission mechanism configured to be powered by a motor. The motorized vehicle is configured such that the motor is housed inside a wheel of the transmission mechanism forming a drive wheel of the propulsion means called a motor wheel. The propulsion means being supported by a bogie comprising an upper bogie rigidly attached to the chassis and a lower bogie, connected together by a suspension mechanism. The lower bogie is articulated with respect to the upper bogie. The motor wheel is rigidly attached to the lower bogie at the rear thereof.

Various of the disclosed embodiments concern a safety apparatus that is positioned adjacent to and attached to a carriage device, thereby substantially improving the safety of individuals seated in the carriage device. The safety apparatus can include a structural frame, one or more front contacts, one or more rear contacts, a support bar, one or more handles, and at least one connector. The at least one connector allows the safety apparatus to be detachably connected or fixedly attached to the carriage device. The safety apparatus may also be adjustable or collapsible, which permits its footprint to be reduced when not in use. In some embodiments, the safety apparatus includes a support bar and/or basket that allows a user to hang or place items, such as a purse or diaper bag, without causing the safety apparatus or the carriage device to become unbalanced.

Provided is a cart robot having a charge function, which includes: a main body having a container in which goods are contained, a handle assembly installed on one side of the container, a battery module, and a battery management system (BMS) module for managing charge and discharge of the battery module; wheel assemblies rotatably coupled to a lower portion of the main body, and configured to move the main body in a direction of a force applied to the handle assembly; and an external charge module (CM) having a front connector provided on a lower front side of the main body and a rear connector provided on a lower rear side of the main body, electrically connected to an external power supply through the front or rear connector and configured to charge the battery module.

A multi-shelf storage apparatus for storage of articles, comprising a wheeled base; a frame disposed on the wheeled base; a plurality of vertically-spaced shelves on the frame for providing a storage area for articles, each shelf configured to move vertically. The apparatus includes a lift mechanism disposed on the frame, coupled to the shelves, and configured to cause collapse and extension of the shelves in a vertical direction. The apparatus has an actuator on the frame operable to drive the lift mechanism, and a power interface on the frame and electrically connected to the actuator. The apparatus has a mechanical connection for connecting to a towing device and a first power interface integral to the mechanical connection such that the actuator can receive electrical power from the towing device. Systems comprising one or more of the apparatuses and methods for loading/unloading articles utilizing the apparatuses are also disclosed.
