Rotating telescopic stair with handrail

Abstract

The invention discloses a rotating telescopic stair with a handrail. The rotating telescopic stair with the handrail comprises a motor, a guiding wheel, a retraction winding rope, a telescopic sleeve segmented column, stair treads and handrail guard bars. The telescopic sleeve segmented column is formed by sequentially connecting a plurality of sub segmented columns with the gradually-decreased diameters. The stair treads are arranged on the sub segmented columns respectively. The guiding wheel is arranged on one side of the motor. A winding and unwinding wheel is installed at the end of the motor. The upper end of the retraction winding rope is connected with the winding and unwinding wheel through the guiding wheel. The lower end of the retraction winding rope is connected with the bottommost sub segmented column. The handrail guard bars are installed at the upper portions of the stair treads respectively. In this way, the rotating telescopic stair with the handrail can be hidden at the upper portion of an attic when indoor space is limited or the stair is not used; when unfolded, the rotating telescopic stair with the handrail is elegant in design and firm in structure, people can conveniently walk upstairs and downstairs, and in addition, the safety of the people is ensured due to the handrail.

Description

technical field [0001] The invention relates to the field of telescopic stairs, in particular to a revolving telescopic staircase with handrails. Background technique [0002] In order to facilitate the passage between floors, various stairs have been invented. General stairs are of fixed structure. Once the construction is completed, the position is difficult to change, which has a great impact on the indoor layout. Moreover, fixed stairs take up a lot of space. For small-sized families, attic telescopic ladders are often used. Solve temporary floor traffic problems. [0003] The attic telescopic ladder is small in size, flexible in extension, and can be stowed away when not in use, without affecting the traffic on the ground floor. It is more popular among home users. At present, the attic telescopic ladders on the market mainly adopt a continuous cross-stretching structure, which has low strength and poor mechanical stability, and most of the attic telescopic ladders do...

AI Technical Summary

Problems solved by technology

At present, the attic telescopic ladders on the market mainly adopt a continuous cross-stretching structure, which has low strength and poor mechanical stability, and most of the attic telescopic ladders do not have handrails on both sides for the convenience of expansion and contraction, so the safety of going up and down the stairs cannot be guaranteed. The structure is simple, which has a certain impact on the decorative effect of the house and lacks aesthetics
