WHEEL DEVICE FOR WALKER AND SELF-WALKING SUPPORTER

摘要

PROBLEM TO BE SOLVED: To surely operate a system in accordance with the braking request of a user, to provide sufficient durability performance even in long-term usage and to enable using an inexpensive braking mechanism by providing a braking means in a transmitting means. ;SOLUTION: In this stater 19 of an electromagnetic brake 16, the friction material 20 of the stater 19 secures a prescribed interval from the outer surface of an armature 15 and the flange 21 of the stater 19 is fixed to a fixing board 5. When the electromagnetic brake 16 is energized, a magnetic circuit is formed between the stater 19 and the armature 15 and the armature 15 is sucked to the side of the stater 19. In this case, the friction material 20 is tightly adhered to the armature 15 to brake the rotation of a sixth gear 14. Thus, the rotation of the whole transmitting means is braked and the wheel 1 is braked. When energizing of the electromagnetic brake 16 is stopped, the magnetic circuit is eliminated, the armature 15 is recovered at the side of the sixth gear 14 by a leaf spring 17 and the rotation of the whole transmitting member is enabled.;COPYRIGHT: (C)2000,JPO
