The engagement protrusion 5 of the upper tread 4 is brought into contact with the upper edge of the angle adjustment plate 7 that closes the staircase, and the engagement protrusion 5 of the lower tread 4 is brought into contact with the lower edge of the angle adjustment plate 7. The purpose is to provide a staircase in which the angle of the tread can be adjusted to be horizontal depending on the installation location.

本考案を以下実施例により詳述する。The present invention will be explained in detail below using examples.

形成されている。A concave groove 2 and a running groove 3 are provided at substantially the center of the opposing inner surfaces of the stringer 1, respectively, along the entire length in the longitudinal direction, and the running groove 3 is provided approximately at the center of the concave groove 2. It opens into the concave groove 2, and flanges 8 are provided on both side edges of the running groove 3, leaving a gap 10 in which a shaft 9, which will be described later, can run freely, and the running groove 3 is fitted into the stringer 1. It is made of metal C channel.

踏板４の両側端面には上記凹溝２の深さと略等しい長さ
で突出する係合突部５が設けてあり、係合突部５の巾は
凹溝２の溝巾と略同−で゛凹溝２内で゛回転できるよう
になっている。Engagement protrusions 5 are provided on both end faces of the footboard 4 and protrude with a length approximately equal to the depth of the groove 2, and the width of the engagement protrusion 5 is approximately the same as the width of the groove 2. It is designed to be able to rotate within the groove 2.

突起６は係合突部５の端面略中央より突出し、前記フラ
ンジ８間の隙間１０を通る軸９と、走行溝３内で回転且
つ摺動自在となった引掛具１１とで構成されている。The protrusion 6 protrudes from approximately the center of the end face of the engagement protrusion 5 and is composed of a shaft 9 that passes through the gap 10 between the flanges 8 and a hook 11 that is rotatable and slidable within the running groove 3. .

である。On the other hand, as shown in the figure, the angle adjustment plate 7 is a long plate material 12 having the same depth and width as the concave groove 2, and is moved in the width direction at the same angle α as the mounting angle of the stringer 1. When assembling the stairs, the angle adjustment plate 7 is fitted into the groove 2 between the treads 4, and the upper and lower edges of the angle adjustment plate 7 are fitted with the upper and lower treads 4, respectively. Each footboard 4 is positioned horizontally by bringing the bottom or top surface of the engagement protrusion 5 into contact with each other, and by preparing angle adjustment plates 7 of various angles,
Stairs can be assembled according to site conditions.

図中１３は上段の踏板４前縁と下段の踏板４の後縁との
