摘要： An all-terrain wheelchair includes a rigid and easy-to-assemble frame. The frame has a seating area with armrests toward the rear of the frame and an adjustable footrest area toward the front of the frame. Attached to the rear axle of the frame and outside the seating area are found two large rear wheels of a sufficient width to provide flotation over soft surfaces. Attached to the front axle of the frame in front of the footrest area is a single large wheel of a sufficient width to provide flotation over soft surfaces. An ergonomically designed push handle is found at the upper rear of the frame behind the seating area, which allows an assistant to propel the chair forward or pull it backward. The frame in front of the front wheel forms a pull handle, which allows an assistant to pull the chair forward or push it backward. A locking brake mechanism is attached to the rear axle to prevent a rear wheel from travel and render the wheelchair motionless when necessary.

摘要： Because sidewalks are sloped for rain, one arm may tire before the other when pushing a stroller or wheelchair because it constantly requires more force from one hand to offset gravity in order to go straight. A slip clutch to couple/uncouple the rear wheels acts like AUTOPILOT STEERING, and that makes pushing more efficient, easier/less strain, on any surface. The slip clutch automatically couples/uncouples the wheels depending on the force difference applied by the hands pushing. When the force difference is moderate, the combined force will 100% efficiently propel straight! Without a slip clutch, even a moderate difference in force will cause some zigzagging which is less efficient and takes more energy than going straight. To turn, the force difference is intentionally greater to automatically uncouple the two wheels to allow turning. Turning requires more energy—that's the tradeoff. However, conveyances are pushed straight most of the time.
摘要翻译：因为人行道因为下坡而倾斜，所以当推婴儿车或轮椅时，一只手臂可能会轮到另一只手臂，因为它一直需要更多的力量来抵消重力，以便直线行驶。用于连接/分离后轮的滑动离合器的作用类似于AUTOPILOT STEERING，这使得在任何表面上推动更有效，更容易/更小的应变。滑动离合器根据手推动施加的力差自动地联接/拆开车轮。当力差中等时，合力将100％有效推进！没有滑动离合器，即使是适度的力的差异也会导致一些锯齿形，效率较低，比直线运动需要更多的能量。为了转动，力差有意地更大，以便自动地分离两个车轮以允许转动。转动需要更多的精力 - 这就是权衡。不过，交通工具大部分时间都是直接推送的。

摘要： Sloped-for-rain urban sidewalks are horrible for wheelchair users because of the constant veering-off threat caused by gravity. Anybody who tries to self-propel a wheelchair on a city sidewalk for the first time is in for a rude awakening—the user must use one hand to steer by retarding one wheel, and that makes propelling inefficient, difficult and frustrating, to say nothing of the dangerous veering-off threat. Applicant's solution is to provide joining means to couple and uncouple the drive wheels. The joining means, when coupled, causes the two drive wheels to rotate in unison preventing the wheelchair from veering-off so that it travels straight when traversing a sloped surface, and when uncoupled allowing the two drive wheels to rotate at different speeds to allow turning. Joining means comprises: slip-clutch, gear configuration or the like, and may be automatic or user controlled.
摘要翻译：对于轮椅使用者来说，倾斜的城市人行道是可怕的，因为重力造成的持续的偏离威胁。任何试图在城市人行道上自行推动轮椅的人都是为了一个粗鲁的觉醒 - 用户必须用一只手来拖动一个轮子，这使得推动效率低下，困难和令人沮丧的无言而喻的危险的退化威胁。申请人的解决方案是提供连接和解耦驱动轮的连接手段。联接装置当联接时，使得两个驱动轮一起旋转，防止轮椅偏离，使其在横过倾斜表面时直线行进，并且当脱开时允许两个驱动轮以不同的速度旋转以允许轮转。联接装置包括：滑动离合器，齿轮构造等，并且可以是自动的或用户控制的。

摘要： A molded braking and support wheel assembly for a multi-wheeled wheelchair for a handicapped person. The wheel assembly includes a braking support wheel molded as a single unit of plastic or plastic-like material having concentric components including a tire receiving rim, a wheel bearing and brake assembly receiving hub, and spaced wheel spokes substantially radially extending between the hub and rim. A ring or band-shaped metal brake drum is also molded as a unit into the hub, the brake drum having a generally cylindrical inner braking friction surface and plastic-interlocking outer surface features which permanently interlock with the plastic material when the braking support wheel is mold formed. The plastic-interlocking outer features are molded with the hub into a single unit with the support wheel to secure the brake drum from relative movement in the hub. The brake drum defines a generally cylindrical cavity for operatively receiving the brake assembly. The hub includes a wheel bearing cavity coaxial with said brake drum for receiving spaced wheel bearings positioned therein.

摘要： Automatic locking systems for wheelchairs have a locking hub for attachment to a main wheel of the wheelchair, and a lock pin which is reciprocally rectilinearly moveable between locked and unlocked conditions with the lock hub. A rotary actuator is operatively coupled to the lock pin and is rotatable between normal and active positions which responsively causes the lock pin to move rectilinearly between its unlocked and locked positions, respectively. A pivotal actuator lever is provided having one end positionable in close proximity to a seat of the wheelchair. The actuator lever is thus mounted for pivotal movements between raised and lowered conditions relative to the wheelchair seat. A flexible actuator cable connects a proximal end of the actuator lever and the rotary actuator. In operation, therefore, pivotal movement of the distal end of said actuator lever between its raised and lowered conditions responsively causes the actuator cable to rotate the rotary actuator between its normal and active conditions, respectively. As a result, the lock pin is caused to move to its locked position with the lock hub to thereby lock the main wheel of the wheelchair and prevent its rolling movement across the floor surface.
