The utility model provides an improved rail structure of a staircase lifting chair, in particular an improved structure capable of enhancing the strength of the rail. The staircase elevating chair is composed of a seat, upper and lower rails, a support column and a scaffold. The lower end of the seat is provided with gears, which can be inlaid with the rail; the upper rail and the lower rail are long strips, which can be bent at the corner of the stairs, and the two sides of the rail are cut into planes separately, with screw holes for screw fixation on the support column; the top face of the lower rail is cut with racks for inlaying with the gear of the seat. The upper and lower rails are mainly solid metal strips, and the upper end face of the lower rails is directly cut into gear racks. When used, the combination of the rails and seats can be more stable and has considerable practicability.

楼梯升降椅的轨条改良结构
本技术涉及一种楼梯升降椅的轨条改良结构,其上、下轨条为实心金属条,可随着楼梯的转角弯折,并于该下轨条顶端面上直接切削有齿排。
技术介绍
传统住家多为凭借楼梯来到达欲到的楼层,对于一些行动不便的老年人或残障人士,要上下楼梯比较困难,而造成使用上的不便。因此,请参阅图1及图2所示,为了提供行动不便的老年人或残障人士方便上下楼梯,市面上有楼梯升降椅,其上轨条10及下轨条11是中空金属管,该下轨条11由支杆110及齿排111所组成,并在侧边设有定位片1100,供齿排111焊接其上。然而在组装时,需分别连结固定,较为麻烦不便,且该齿排111于突出的定位片1100所焊接而成,故结合不够稳固,且若楼梯宽度较窄时,升降椅与对向墙壁距离极近,而使乘坐者过于压迫而不舒适,且影响到楼梯空间。此外,上下轨条都为直条状无法弯折,所以上、下楼梯时升降椅不能转弯,也即要在转弯处分别另外设置一个升降椅,增加其制作成本,而具有此缺失。技术设计人有鉴于现有楼梯升降椅轨条使用上的缺失,为使轨条能与座椅稳固结合及提升升降椅与楼梯的空间,以此为研究的课题,乃本着精益求精的精神,首 ...
【技术保护点】
1.一种楼梯升降椅的轨条改良结构,该楼梯升降椅由座椅、上轨条、下轨条、数个支撑柱及数脚座所组成,该座椅的下端设有齿轮,该齿轮能够嵌合于轨条的齿排;该上下二轨条的两侧端切削为平面,并开设有数个螺孔,以螺固于支撑柱上;数个该支撑柱的下端连接有脚座,使其能够固定于楼梯的梯面;其特征在于:该上轨条、下轨条是实心金属条,且该下轨条的顶端面直接切削成齿排。
