摘要： Electrically powered four-wheeled single vehicles especially for disabled persons and invalids and specifically made for out-door use must have such stabilizing qualities that under all circumstances there is no risk for the chair to turn over even if it will have to force different kind of obstacles such as curbs. A further object of such vehicles is to provide a simple and safe steering operation so that the forces from the obstacles to be forced must not be transmitted to the steering handle, since patients in many cases have considerably reduced power to control such forces by hand. These objects are realized in the present invention substantially by the fact that the vehicle comprises a rear and a front portion which are swingably connected to each other by means of telescopic pipes or the like running substantially in parallel with the ground and in the longitudinal direction of the vehicle. To meet the requirement of a safe and unaffected steering operation the front wheels are neutrally positioned in a way that the extension of the swivel axles will cut the contact surfaces between the corresponding wheels and the ground.

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，困难和令人沮丧的说不出话来的危险的退化威胁。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： The present invention relates to a wheelchair with forced driven front caterpillar wheels with a cable-hauling ratchet lever by which a user, by himself/herself, can pass over a road-block or drains on roads, lifts up the caterpillars from the ground for easy steering on caster wheel, engages/disengages the drive wheel having ratchet clutch in the detachable wheel hub to idle the drive wheel/caterpillars for converting from/to manual drive to/from drive by auxiliary power source, and prevents the drive wheel from rolling backward during climbing inclines and controls speed continuously on a slope by a band brake means. So the disabled persons on their legs can travel to outdoors by himself/herself without a care of neighbors.

摘要： A wheelchair is disclosed that comprises a drive system that includes typically two input members carried for oscillatory movement on a frame of the wheelchair. A transmission is system disposed to mechanically interconnect each input member to a respective main ground-engaging wheel of the wheelchair. The transmission system is configured such that oscillatory movement of the input member causes rotational movement of the wheel, thereby enabling a user of the wheelchair to propel it by applying effort to the input member. Independent movement of the two input members can be used to effect steering control of the wheelchair. The wheelchair preferably also has a braking system to resist movement of the main wheels.

摘要： A wheel hub (10), primarily for a wheelchair wheel, can be manually operated by rotating a cover (168) to give three different operating states for the wheel which includes the hub. In the first position, the wheel is free to rotate relative to the chair. In the second position, the wheel is locked to the chair, i.e. the chair is braked. In the third position, the wheel can turn in the direction corresponding to forward motion of the chair, but cannot rotate in the opposite direction. This prevents the wheelchair from undesired backward rolling movement.
摘要翻译：可以通过旋转盖（168）来手动操作用于轮椅轮的轮毂（10），以给包括轮毂的车轮提供三种不同的操作状态。在第一位置，轮相对于椅子自由旋转。在第二位置，车轮被锁定在椅子上，即椅子被制动。在第三位置，车轮可以在与椅子向前运动相对应的方向上转动，但是不能沿相反方向旋转。这样可以防止轮椅出现意外的反向滚动。
