Abstract: In a power transmission mechanism 20, a line connecting a center shaft 21 of a reference gear member 40 and a first shaft 44 of a first planetary gear member 42 and a line connecting the center shaft 21 of the reference gear member 40 and a second shaft 47 of a second planetary gear member 45 form a specific angle α. Rotation in one direction is prevented when a first carrier member 22 and a second carrier member 32 are relatively rotated in a direction to decrease the specific angle α. Further, a rotation prevention release unit is provided to release a prevention state of the rotation when the first carrier member 22 and the second carrier member 32 are relatively rotated in a direction to increase the specific angle α.

Abstract: Because sidewalks are slanted for rain run-off, they pose a safety risk for baby strollers if the person pushing the stroller stops and doesn't apply the brake. If s/he releases the stroller's handle when the brake is not applied, the stroller may veer off towards the curb owing to gravity, wind, the baby's movements, traffic vibrations, etc. Not applying the brake when stopped is a common mistake. While parents may remember to apply the brake when stopped, other caregivers may not. Applicant's improvement provides fully automatic slip-clutch joining means to inhibit veering off by automatically coupling the stroller's rear wheels together when the stroller is stopped. When coupled, the rear wheels must rotate in unison thus helping to prevent the stroller from veering-off toward the curb. When the stroller is being pushed the slip clutch handily becomes disengaged by turning or making other course adjustments.

Abstract translation: 因为人行道倾斜为雨水径流，如果推婴儿车的人停止并且不施加刹车，则婴儿车会安全隐患。 如果不使用制动器，他/他会释放婴儿车的手柄，婴儿车可能由于重力，风，婴儿的动作，交通振动等而向路边转弯。停车时不应用制动器是一个常见的错误。 虽然父母可能会记得在停车时应用制动器，但其他照顾者也许不会。 申请人的改进提供了全自动的滑动离合器接合装置，以在婴儿车停止时通过将婴儿车的后轮自动地联接在一起来抑制旋转。 当联接时，后轮必须一致地旋转，从而有助于防止婴儿车向路边转向。 当婴儿推车被推动时，滑动离合器通过转动或进行其他过程调整而轻松脱离。

Abstract: A hub assembly for a wheelchair has a hub device and a switch device. The hub device has a hub shell, an axle, a ring and a ratchet. The ratchet has a cylinder section. The cylinder section has a recess formed in an outer surface of the cylinder section. The switch device has a pin and a wire. The pin is capable of being selectively inserted into the recess. The wire is securely connected with the pin. Because the pin is inserted into the recess and the ratchet engages the ring, the hub shell along with a wheel cannot be moved unintentionally backward on a ramp.

Abstract: 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.

Abstract: A wheelchair wheel hub locking mechanism is provided to positively lock a wheelchair wheel to the associated wheelchair frame and includes a locking ring member of cylindrical shape fixed to the inner side of the wheelchair wheel hub, the locking ring providing a plurality of dog receiving cages, each cage presenting a dog receiving opening formed by surround walls integral of the ring. A dog and dog mounting plate are mounted to a member of the wheelchair frame, the position of the dog being controlled by movement of an association handle connected by a cable to the dog, forward movement of the handle raising the dog away from cages of the locking ring, movement of the handle rearwardly of the wheelchair allowing the dog under spring bias to move against the locking ring until wheel movement aligns a cage of the ring with the dog and the two lock up.
