阅读说明：本技术 一种升降阁楼折叠楼梯 (Foldable stair with lifting attic ) 是由 岳海亮 于 2021-09-27 设计创作，主要内容包括：本发明一种固定安装于阁楼升降平台底部,依靠电机作为动力驱动,动力联动杆连接推动通过铰链或者销子固定连接与驱动支架上的楼梯,实现在升降阁楼的升降支架平台下降时攀爬楼梯可以折叠伸展出便于上下攀爬,升降阁楼升降支架平台上升,不需要楼梯上下攀爬时将楼梯折叠隐藏收纳于升降阁楼升降支架平台底部,并随升降支架平台上升；节省了攀爬楼梯对于地面空间的占用。(The stair climbing device is fixedly installed at the bottom of an attic lifting platform, and is driven by a motor as power, and a power linkage rod is connected with and pushes the stair fixedly connected with a driving support through a hinge or a pin, so that the climbing stair can be folded and stretched out to be convenient for climbing up and down when the lifting support platform of the attic is lowered, the lifting attic lifting support platform rises, and the stair is folded and hidden to be accommodated at the bottom of the lifting attic lifting support platform and rises along with the lifting support platform when the stair does not climb up and down; the occupation of climbing stairs to the ground space is saved.)
