Abstract: The invention relates to a carrier frame for a manually movable caddie, in particular to a golf caddie comprising wheels (2) mounted on the laterally protruding parts (7, 8) of the fame. According to the invention, for folding the golf caddie, the laterally protruding parts (7, 8) of the frame are embodied pivotable and/or displaceable in such a way that they bring the wheels (2) closer to each other towards a mid-plane (18) or move them away therefrom. In a preferred embodiment, the protruding parts (7, 8) of the frame and the wheels (2) are embodied pivotable or displaceable in such a way that the axes of the brought together wheels (2) coincide and the wheels (2) are disposed oppositely to each other by the external faces thereof.

Abstract: A collapsible pushchair can be expanded into a deployed state for carrying a child and collapsed into a portable state for being carried as a piece of luggage. Transformation of the pushchair between its deployed and portable states is enabled by the use of rotationally mounted chair legs.

Abstract: A variable wheel positioning vehicle has a wheel position changing mechanism and a wheel position control device to change a wheel position of a wheel with respect to a center of gravity of a vehicle body. The wheel position changing mechanism is arranged to move a suspension device along a movement path with respect to the vehicle body and to hold the suspension device at any position along the movement path. The wheel position control device issues a movement command to the wheel position changing mechanism that changes a wheel positioning distance between a center rotation axis of one of the wheels and the center of gravity of the vehicle body as measured in a direction parallel to an acceleration direction of the center of gravity of the vehicle body based on a traveling condition the vehicle.

Abstract: The disclosure is generally directed toward vehicle support systems. In one embodiment of the invention, first and second support assemblies can be pivotally coupled to a base. A control mechanism can couple the first and second support assemblies together and be configured to control pivotal movement of the support assemblies between spread and stowed positions. In another embodiment, first and second support assemblies can be pivotally coupled to a base and to first and second wheel assemblies. First and second steering mechanisms can be coupled to the first and second wheel assemblies and the first and second support assemblies. A control system can be operatively coupled to the first and second steering mechanisms and can be configured to command selected angular positions of the first and second wheel assemblies relative to the base by compensating for the support assemblies being in various positions.

Abstract: Disclosed is a lightweight caster assembly and modular shelf system for use on an existing collapsible foldable cart with four wheels.

Abstract: The disclosed articulated wheel assemblies and associated vehicles, for example wheelchairs, include articulated wheel assemblies with at least one offset connecting arm rotatably attached at one end to a payload platform, for example a seat, and attached at the other end to a linear actuator, where the linear actuator is further connected to a wheel. Embodiments include a rotary actuator for varying the linear actuator swing angle, a rotary actuator for eccentrically rotating a hubless wheel, a linear actuator motor for varying the length of the linear actuator, and a propulsion motor. Embodiments provide omnidirectional motion, stepping action when presented with obstacles, irregular surface negotiation, tight space maneuvering and other features to provide disabled people increased mobility. Alternate embodiments include a payload platform with a support strut, which is rotatably attached to an offset connecting arm and pivotally mounted to a seat.

A pair of side members are oppositely coupled to the base member. Each of the side members is positioned substantially orthogonally to the base member. The side members are designed for engaging the object for inhibiting the object from tipping off of the base member when the object is positioned on the base member. At least one wheel is rotatably coupled to each of the side members. The wheel is designed for rollably engaging a support surface for facilitating movement of the object across the support surface when the object is positioned on the base member and the base member is moved across the support surface by the user.

Abstract: A method and apparatus for ground working. A first step involves providing an apparatus for ground working with telescopically extendible wheel supports which permit the height and angular orientation of the chassis to be adjusted to suit a contour of a ditch. A second step involves positioning the apparatus with at least one support wheel in the ditch and at least one support wheel on the road. A third step involves driving along the ditch broadcasting gravel from the ditch onto the road with the drum. Instead of hauling in replacement gravel from a remote site, gravel is reclaimed from the ditch and broadcast back onto the road.

Abstract: A seat back recliner kit for attachment to a wheelchair which does not have a reclining seat back. A separate recliner mechanism is attached to each side frame for the wheelchair. Each recliner mechanism includes a rear wheel mounting bracket which attaches to the side frame for providing one or more rear wheel mounting locations spaced further to the rear of the wheelchair than the original rear wheel mounting locations. The new rear wheel mounting locations provide stability when the wheelchair is occupied with the seat back reclined. A pivoting seat back support is attached to the rear of each wheelchair side frame and the wheelchair seat back is attached to the pivoting seat back supports. An adjustable length brace extends between each seat back support and a rear wheel mounting block for adjusting the seat back angle. The brace is released by operating a hand lever while the seat back angle is adjusted and is locked when the lever is released.
