Embodiment Construction

[0120] According to the invention, the vehicle arrangement has at least one castor wheel mounted on the vehicle frame for swivel movement about a vertical axis. The caster is controlled by a steering mechanism for manipulating the direction of the caster. A disconnect is provided to disconnect the caster from the steering mechanism so that the caster is free to turn as the vehicle is propelled or powered. The steering assembly can be disconnected and has two working positions:

[0121] (a) an "off" or pushable / stroller position in which a locking pin or similar device disconnects the steering mechanism and caster assembly so that the caster can swivel freely when a caregiver pushes or pulls it; and

[0122] (b) "Linked" or rider-operable position in which a locking pin or similar device connects the steering mechanism to the caster assembly so that the caster can be steered within a limited range of swivel by an occupant-operated steering wheel or lever arrangement.

Abstract

A vehicle with a caster (12) has a disconnectable steering system so the vehicle can be quickly and easily converted back and forth between rider-steerable and externally steerable configurations. The vehicle includes a frame (body) (20), the caster, and a steering mechanism (22, 24, 34) mounted on the frame. A disconnecting device (32) is mounted between the steering mechanism and the caster. When the disconnecting device connects the steering mechanism to the caster, the vehicle can be steered by the occupant since the steering mechanism and caster rotate as one unit. When the disconnecting device disconnects the steering mechanism from the caster, the caster is allowed to swivel freely (360 DEG ) about its vertical axis so that the vehicle can be pushed or pulled in any direction by an external operator. The vehicle may be a stroller, a toy vehicle, a scooter, a wheelchair, a cart, a dolly, etc., and it can have more than one caster.

Description

technical field [0001] The present invention relates to a vehicle on castors, and more particularly to a switchable swivel control to enable the vehicle to be properly controlled whether the vehicle is steered by the driver or externally. Background technique [0002] Many vehicles are constructed with casters - turnable wheels that swivel - allowing the vehicle to roll on the road. The axle of a wheel is usually horizontal, while its axis of rotation is usually vertical. Casters can be attached to any vehicle or any rollable item, object or device, such as the underside or legs of a piece of furniture, a cart, a wheelbarrow or other heavy object to make it easier to move. [0003] Casters are generally utilized as the front wheels of externally driven rolling vehicles, such as strollers, wheelchairs, wheelbarrows, office chairs, etc., which are usually pushed or pulled by a person or energy source separate from them. Each caster typically includes one or more vertically o...
