Linear ladder-chair

Abstract

The invention relates to a linear ladder-chair, comprising two supports, a support plate, a rest plate and linkages. One side of the upper end of one support is fixedly connected with one side of the upper end of the other support through a first link, and the other sides of the upper ends of the supports are fixedly connected through a second link; the upper end of each support is provided with a support rod close to the second link; one end of the support plate is provided with a slide, and the other end thereof is connected with the rest plate; the first link is slidably disposed in the slide; the other end of the rest plate is connected to the upper ends of the support rods; the support plate and the rest plate are provided with footplates, respectively; two ends of a connection of the support plate and the rest plate are provided with the linkages, respectively; the other ends of the linkages are disposed on the second link. The linear ladder-chair can serve as both a chair and a ladder and is simple in structure and convenient to transform.

Description

technical field [0001] The invention relates to the field of daily life, in particular to an inline ladder chair. Background technique [0002] In family life, sometimes it is necessary to pick and place items at a high place or replace a light bulb. At this time, it is necessary to use a ladder or superimpose other supporting devices on the chair surface; the former is not equipped in many families due to its low frequency of use and the need for storage space. , the latter is prone to safety accidents due to the unreliable connection between the two. Therefore, we have developed a one-line ladder chair, which can be used not only as a chair, but also as a ladder, and has a simple structure and is easy to change . Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide an inline-shaped ladder chair, which can be used not only as a chair but also as a ladder, and has a simple structure and is easy...
