Telescopic adjustable staircase
The invention discloses a telescopic adjustable staircase which comprises main steps and telescopic steps. One telescopic step is arranged below each main step. Each step is provided with two guide rail grooves, a first limiting hole and a second limiting hole, wherein the guide rail grooves are arranged above the main step, and the first limiting hole and the second limiting hole are arranged onthe middle line of the main step. Each telescopic step is provided with movable small wheels, a fixed spring and a pin, wherein the movable small wheels are arranged below the telescopic step and located on the guide rail grooves, a groove is formed in the center of the upper outer side of the telescopic step, the fixed spring is connected with the pin and arranged on the edge of the groove, the upper edge of the pin is provided with a sheet, and the sheet is located in the groove. According to the staircase, the height and the width of a single stair step can be adjusted through the expansionand contraction of a pedal, and the mode suitable for walking of normal adults or the mode suitable for walking of old people with difficulty in walking and children is switched.
本发明公开了一种伸缩可调节楼梯，包括主台阶和伸缩台阶，每级主台阶的下方设有一级伸缩台阶，所述主台阶上分别设有两根导轨槽、第一限位孔和第二限位孔，所述导轨槽设置于主台阶的上方，所述第一限位孔和第二限位孔设置于主台阶的中线上，所述伸缩台阶上设有移动小轮、固定弹簧和销，所述移动小轮设置于伸缩台阶的下方，位于导轨槽上，所述伸缩台阶上外侧中心处设有凹槽，固定弹簧和销连接，设置于凹槽边缘，所述销的上边缘设有薄片，所述薄片位于凹槽中。该楼梯可以通过踏板的伸缩来调节单个楼梯台阶的高度和宽度，切换出适合正常成年人行走或适合腿脚不便的老年人及小孩行走两种模式。
