Title:
勾配可変階段装置
Document Type and Number:
Japanese Patent JP7379799
Kind Code:
B2
Abstract:
To provide a variable gradient staircase device capable of experiencing multiple stairs with different slopes in a small space.SOLUTION: A staircase 10 includes: a vertical member 14, a lower member 16 and a diagonal member 18 the tilt angle θ of which is adjustable with respect thereto; a bolt 44 positioned between a step member 34 and a riser member 36; and a bolt 40 that is fixed to the riser member 36. The bolt 44 supports the riser member 36 rotatably with respect to the step member 34 so that the angle θ' between the riser member 36 and the step member 34 is adjustable. The bolt 40 is movable in a long hole part 48 of the riser member 36 and fixes the riser member 36 and the diagonal member 18. With this, the riser member 36 can be fixed to the diagonal member 18 with the angle θ'of the riser member 36 adjusted with respect to the step member 34, and the diagonal member 18 can adjust the slope of staircase 10 simply by adjusting the tilt angle θ. As a result, in a space where the staircase 10 is installed, multiple staircases 10 with different gradients can be experienced.SELECTED DRAWING: Figure 2
