The below illustrates principle of work of the present utility model according to Figure 10 ~ 12:
Motion process 1: handrail is opened.
Motion process 2: handrail slides.
When integrated gear 2 can rotate, because the first gear 20 and first tooth-shape structure 11 maintenances of rack rails 1 of integrated gear 2 are meshed, so integrated gear 2 can slide along rack rails 1.Therefore, in this case, can promote as long as apply the power that it moves forward and backward to handrail lid 7, the stop bit spare of its lower surface 9 will promote glide base 3 and moves forward and backward, glide base 3 drives integrated gear 2 again and slides along rack rails 1, thereby the occupant just can promote according to the needs of oneself handrail lid 7 along rack rails 1 front and back slip.
Motion process 3: handrail is located.
When handrail lid 7 slides into the position of expectation, unclamp activation members 60, sliding part 62 will with integrated gear 2 on inversed taper platform 22 separate, thereby make integrated gear 2 lose the thrust of sliding part 62.Due to the bounce of spring 4 and the effect of integrated gear 2 self gravitations, integrated gear 2 will be along S. A., move to the direction away from spring 4, until the first inclined-plane 213 on the second gear 21 touches the first inwall 34 on glide base 3, under the effect of the first inclined-plane 213 and the first inwall 34, integrated gear 2 will promote glide base 3 and move to the front end of handrail lid 7.
When the first end face 201 of the first gear 20 touches the groove floor 10 of rack rails 1, the second gear 21 on integrated gear 2 again with glide base 3 on tooth-shape structure 31 engagement, make integrated gear 2 can not rotate again, thereby make glide base 3 remain static together with handrail lid 7.At this moment, because integrated gear 2 is subject to the engagement restriction, so even thrust is arranged on handrail lid 7, handrail lid 7 also can not slide front and back, so just can realize simply and easily the positioning function of handrail lid 7.
Above-described, be only preferred embodiment of the present utility model, be not to limit scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Be that simple, the equivalence that every claims according to the utility model application and description are done changes and modify, all fall into the claim protection domain of the innovation patent of invention.
