Embodiment Construction

[0039] In embodiments, a retractable staircase system and uses thereof are disclosed.

[0040] Referring now to the accompanying drawings, and more particularly to Figure 1A -C, showing an embodiment of a fully extended retractable staircase (10) assembled with at least one high lateral guard (20) or at least one low lateral guard (30). The retractable staircase (10) is incrementally adjustable to any number of different heights. The high lateral guard (20) includes a top rail (22), a middle rail (24), a bottom rail (26) and at least two central posts (28). The low lateral guard (30) includes a top rail (32), a bottom rail (36) and at least two center posts (38). A first part (40) of the high or low lateral guard (20, 30) is retractable into a second part (50) of the high or low lateral guard (20, 30) and is accessible from the second Partially extended, giving the staircase retractable properties. The size of the structure of the first part (40) of the high or low lateral...

Abstract

The invention relates to a telescopic staircase to be installed on construction sites for providing a safe staircase for workers during building construction. The telescopic staircase comprising at least one lateral guard comprising a top rail, a bottom rail and at least two newels, the bottom rail having a plurality of connecting holes, and a plurality of tread assembly comprising a tread plate,at least two stringer portions and at least two pairs of support members, each support member having at least one connecting hole, in which the at least one lateral guard includes a first portion being retractable into and extensible from a second portion, in which each support member substantially forms a 45 DEG angle with the tread plate, and in which the support members are to be attached to the top surface of the bottom rail via attachment means through the connecting holes.

Description

technical field [0001] The disclosed subject matter generally relates to a retractable staircase system and uses thereof. Background technique [0002] Stairs often include a stair rail system for safety. In a stair rail system, handrails are conventionally placed on top of a row of vertical posts along the edge of the stair. These posts (often referred to as balustrades) are supported by relatively large posts called mid-posts. Therefore, stair construction requires a lot of skill and care and can be a lengthy process. Therefore, the installation of any type of stairs may require temporary access to other floors of the building. [0003] Extension ladders have been used for many years to reach greater heights such as the roof of a house. Common extension ladders are usually divided into only two or three extendable pieces. As a result, conventional extension ladders are difficult to transport and require a greater amount of space than desired during storage and / or tran...
