Step ladder integrated with lifting ceiling

Abstract

A step ladder integrated with a lifting ceiling comprises a round rod, a telescopic sleeve and a lifting sleeve. The round rod is vertically fixed on a compartment floor; the telescopic sleeve consists of a plurality of sections of inner sleeves and outer sleeves, and the lower end of the telescopic sleeve is fixed on a carriage floor; the inner sleeve is sleeved on the round rod, outer flanges are arranged at the upper end and the lower end of the inner sleeve, and spiral grooves are formed in the outer flanges; the two adjacent inner sleeves are sleeved with the outer sleeves, spiral protrusions are arranged on the inner sleeve walls of the outer sleeves, step plates are connected to the outer sleeve walls of the outer sleeves, and inner flanges are arranged at the upper ends and the lower ends of the outer sleeves; the lifting sleeve is coaxially sleeved with the round rod, the upper end of the lifting sleeve is fixed to the lifting ceiling, and the lower end of the lifting sleeve is connected with the upper end of the telescopic sleeve. When the lifting ceiling falls down, the telescopic sleeve shrinks, and the stair plates are vertically arranged above the floor. At the moment, the space occupied by each step of ladder plate is greatly compressed, and each step of ladder plate can be used as a commodity shelf for placing articles of daily use. When the lifting ceiling rises, the telescopic sleeve extends, and the step ladder plates are spirally arranged to form the step ladder.

Description

technical field [0001] The invention relates to the field of off-road touring vehicles, in particular to a step ladder integrated with a lifting roof. Background technique [0002] The compartment is an important part of the off-road RV and the living space for the driver and passengers. With the improvement of customer demand, most off-road RVs are equipped with a liftable roof, which can expand the activity space of the driver and passengers. Such as figure 1 As shown, the lifting ceiling 11 is positioned at the top of the compartment 2, and relies on the lifting mechanism to realize lifting. After the lifting ceiling 11 rises, the household items such as folding sofa and lifting coffee table can be opened above the ceiling 12 of the compartment 1, which is convenient for drivers and passengers to use. [0003] If there is a lifting ceiling, there must be a step ladder. If a common folding step ladder is used, a large inclination angle is required to ensure the safety o...

Problems solved by technology

Although the corner step ladder takes up less space, it still takes up valuable space objectively, especially when the lift roof is not in use (most of the time), the corner step ladder has always been an ineffective feature.
