A dolly apparatus, comprising a platform, a plurality of bars coupled with the platform, a handle configured to connect the plurality of bars to each other, and a plurality of casters coupled with the platform. The dolly apparatus has the versatility to accommodate various types and sizes of ladders and transports each of them from one spot to another with relative ease and minimal effort.

A pulling cart with four wheels can be folded into a folded configuration. The wheels are mounted on wheel assemblies which can be in an open or a folded position. The cart has a front panel hinged to a rear panel. The front panel has a front carrier for mounting two wheel assemblies and a pair of slide rails extendable to the second panel. A rear carrier having two wheel assemblies is fixedly mounted to the end portion of the slide rails to move between the front and rear panels. When the cart is used for pulling, all wheel assemblies are in the open position. Each carrier has two arm-receiving holes. Each wheel assembly has a pair of arcuate arms which can rest on the carrier to support the wheel in the open position or move through the arm-receiving hole into the folded position for folding the cart.

Various embodiments herein relate to powered pusher devices configured to push wheeled objects from one location to another. Further embodiments relate to wheeled objects such as carts for transporting items from one location to another. Other embodiments relate to platform powered pushers that can be coupled to a family of various wheeled objects.

A transport device in the form of a cart or cargo hauler is foldable to permit the device to be used in transport applications with narrow or constrained parameters. The device may be loaded or unloaded when folded or unfolded, providing a flexible implementation that improves ease of transport. The device may include one or more wheels or skis depending on a desired application. Handles may be provided that telescope and/or fold to provide a compact folded configuration. The transport device may be folded compactly so as to be carried with a backpack or shoulder harness. The handles may be attached to waist belt or shoulder harness to permit hands-free transport. The device is suitable for use over rough back country terrain or sand.

A tactical transport cart manually navigable over both topographic and hydrographic terrains has a frame, a payload support on the frame, a hard point of attachment or connection on the frame or the payload support, a pair of wheels or other terrain-engaging transport propulsion members attached to the frame, a handle structure attached to the frame, at least one motor connected in driving relation to the transport propulsion members, a battery for providing motive power to the motor, and a control device connected between the battery and the motor for controlling supply of motive power to the motor. The frame, transport propulsion members and handle structure are cooperatively dimensioned and configured for movement of the cart over ground surfaces of topographic terrains and for partially and fully submerged movement over water-covered surfaces of hydrographic terrains.

A ball retrieval apparatus (10, 910) for retrieving (e.g. tennis) balls (70) from the ground (72) includes a receptacle (12, 912) with an opening (26, 926) over which horizontal rods (36, 936) extend. The rods are received in apertures (34), and can move upwardly and laterally between lowermost and raised positions. The distance between rods in their lowermost positions is less than the ball's diameter. This distance increases as the rods are raised, and moved in opposite lateral directions. A ball can be retrieved by being received into the receptacle between adjacent rods. The rods then drop down to their lowermost positions so that the distance between them again decreases so that the ball is trapped in the receptacle. The invention also extends to a ball retrieval system including a trolley (46, 946) and one or two ball retrieval apparatus supported on the trolley.

The assembled-type traveling carriage includes: the telescopic cylindrical body being an extendable telescopic cylindrical body rotatably provided with a first screw at each end thereof, and incorporating an actuator configured to extend and withdraw a nest; a joint block provided with a second screw; a traveler rotatably provided with the first screw and attached a driving device thereto; and a coupling rod rotatably provided with the first screw on each end thereof. A first planar frame body is assembled by screwing joint blocks to four of the telescopic cylindrical bodies, screwing the travelers to the joint blocks such that the travelers are positioned on extension lines of the telescopic cylindrical bodies, and coupling one ends of the four telescopic cylindrical bodies to one another by the coupling rods through the joint blocks.

Maneuverable strollers are disclosed. An example stroller includes a frame that includes an upper frame support, an intermediate frame support, a lower frame support, and a handle coupled to the upper frame support. The example stroller also includes a front wheel coupled to the lower frame support, an intermediate wheel having an axis of rotation, and a rear wheel. The intermediate wheel is located between the front wheel and the rear wheel. The intermediate wheel and the rear wheel are coupled to upper frame support via the intermediate frame support. The example stroller also includes a pivot axis, where the intermediate frame support is coupled to the upper frame support about the pivot axis, and the pivot axis is offset above and forward to the axis of rotation.

A folding handcart includes: a main body provided with at least one wheel unit for moving at a lower portion thereof and provided with a supporter configured to extend vertically from the lower portion thereof; and a loading plate connected to the supporter of the main body through a hinge unit, folded while being rotated toward the main body by the hinge unit, and stowing an article or a folding box, wherein, when the loading plate is folded while being rotated toward the main body, a predetermined stowing space is provided between the main body and the loading plate in accordance with an area of the supporter such that the folding box is folded and stowed therein.
