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.)

1. The utility model provides a lift loft folding stair, its characterized in that includes the folding power drive mechanism of stair, realizes the folding coupling assembling of stair, loft lift platform.

2. The stair-folding power drive mechanism of claim 1 fixedly mounted to the attic lift platform.

3. The assembly of claim 1, wherein the assembly for effecting a folding connection mounts the staircase to a powered drive mechanism or a loft landing.

Technical Field

The invention belongs to furniture, and particularly relates to a folding stair used for a household elevating attic.

Background

As the urban population is large and the house price is high, many people buy small house type houses, the use area of the room is too small, and some families are larger, can utilize living space with high efficiency and use lofts which can be lifted; like the lift loft that patent 201820628108.9 disclosed, the stair of climbing from top to bottom is fixed mounting and places in the one side of lift loft, rises at the lift loft, when not being suitable for the loft to climb from top to bottom, and the idle placing of stair can additionally occupy a part living space and can't accomodate and bring inconvenience for the life.

Disclosure of Invention

In order to solve the defect that the climbing stair for the loft is fixed and occupies the indoor ground space in practical application, the invention provides the climbing stair which is fixedly arranged at the bottom of a lifting platform of the loft and is driven by a motor serving as power, a transmission rod is connected and pushed to fixedly connect and drive the stair on a support through a hinge or a pin, so that the climbing stair can be folded and extended to be convenient for climbing up and down when the lifting platform of the loft descends, the lifting platform of the loft ascends, and the stair is folded and hidden to be accommodated at the bottom of the lifting platform of the loft and ascends along with the lifting platform when the climbing platform of the loft does not need to climb up and down; the occupation of climbing stairs to space is saved.
