Description

Technical Field

[0001] The utility model belongs to the technical field of loft stairs, in particular to a hidden loft telescopic staircase. Background Art

[0002] The attic is the most common building structure in existing buildings. It is set on the roof and is mostly used for storage but can also be used for living. However, because the attic is set on the roof of the building, stairs are needed to enter the attic. In order to ensure that the stairs do not take up too much space and do not affect the aesthetics of the building, most of them use telescopic stairs. The telescopic stairs have telescopic properties and can be stretched out when in use. When not in use, they can be directly squeezed and compressed to reduce their space occupancy rate.

[0003] A Chinese patent application (or patent) with the announcement number CN206987225U discloses an electric hidden staircase, including a hidden staircase, a guide rail, a bookcase and an electric push rod. The hidden staircase includes three steps, each of which is a hollow cabinet. The bookcase includes an outer frame and four internal grids. Due to the function of the guide rail and the guide rail groove, the hidden staircase can slide freely. The utility model is a household item with multiple uses, an electric hidden staircase that maximizes the use of space.

[0004] The above-mentioned electric hidden staircase is provided with a bookcase and steps embedded on the side of the bookcase. However, although the steps in the hidden staircase are hidden, the space occupied by the steps is converted into the space occupied by the bookcase, but the bookcase used to store the steps is still outside and has not been hidden; and there are no guardrails on both sides of the steps in the bookcase, so when stepping on them and climbing up, the safety is poor. At the same time, because the steps are hollow structures, the stability and weighing capacity are low. To this end, we provide a hidden attic telescopic staircase to solve the above-mentioned problems. Utility Model Content
