Description

  The present invention relates to a rotating staircase used when changing the direction of a stairway.

  The wooden indoor staircases of two-story and three-story houses have a surrounding staircase, such as a folding staircase that turns 180 ° in the middle and a bent staircase that turns 90 ° in the middle. A staircase structure is applied.

  On the other hand, in a step-shaped staircase in which both side edges of the step board and the kick board are in direct contact with the wall surface, etc., along the corner between the surface of the step board or the kick board (step surface) and the wall surface. A baseboard is attached, but it is usual to attach a baseboard along the corner in the same way also in the staircase around the staircase.

However, in the conventional surrounding staircase, a plurality of step plates and kick plates are arranged at equal intervals in the circumferential direction between the outer wall surface and the inner wall surface. The arrangement angle (horizontal angle) with respect to the wall surface is different, and the horizontal corners of the corners on both sides of the kick plate for each step are different. For this reason, in the skirting board mounting structure of the surrounding staircase shown in the following Patent Documents 1 and 2, a dedicated skirting board is prepared in each corner so that it fits in each corner. Baseboards are attached to the corresponding corners.
Japanese Patent Laid-Open No. 10-37420 (FIG. 1-10) Japanese Patent No. 2857804 (Fig. 1-3)

  However, in the conventional method of attaching the skirting board of the staircase, since a dedicated skirting board is attached to each corner of each step, there are many types of skirting boards and the types of staircase parts increase. . This makes it difficult to manufacture staircase parts, lowers productivity, increases costs, and requires a lot of labor to select the type of parts when assembling skirting boards, resulting in lower assembly workability. There was a problem.

  In addition, since each baseboard shape is formed in accordance with the shape of each corner, especially when pre-processing staircase components on the factory side as in the pre-cut method, there is some difference at the construction site. In both cases, if a dimensional error or assembly error occurs, the skirting board cannot be stored with high accuracy, requiring troublesome correction work on site, and in this respect, the assembly workability is further reduced. Have

  An object of the present invention is to provide a rotating staircase that can solve the above-described problems of the prior art, reduce the number of parts, improve productivity, improve assembly workability, and reduce costs. .

  As described above, according to the surrounding staircase of the present embodiment, there are only three types of vertical boards for the narrow angle, the wide angle, and the inner corner as the vertical boards provided on the surfaces of the kick plates (31) to (35). Because it is constructed using only the skirting boards (6) to (8), as compared with the case of attaching a dedicated vertical skirting board to both side edges of the kick plate for each step as in the past. By reducing the number of baseboards and reducing the number of parts, it is possible to easily manufacture staircase parts, improve productivity, and reduce costs.

  Further, in plan view, a narrow-angle vertical skirting board (6) is used for a right-angle or acute vertical corner, and a wide-angle vertical skirting board (7) is used for an obtuse vertical corner. Since the vertical corner wood (8) for the inner corner is used at the specific position, the operator can easily and accurately select the use place and the type of the vertical wood (6) to (8).

Since (77) and (78) are formed in parallel with each other, the front surfaces (66) and (76) are perpendicular to the wall surface simply and surely by simply placing the non-exposed side surfaces (66) and (76) along the wall surface. And the exposed side surfaces (67) and (77) can be arranged parallel to the wall surface. Thus, it is possible to easily and accurately align the vertical skirting boards (6) and (7) along the wall surface, and to further improve the assembling workability.

  Especially when the staircase components are processed on the factory side as in the pre-cut method, dimensional errors at the time of assembly can be easily absorbed. Additional workability can be further improved.

However, the present invention is not limited thereto, and the wide-angle vertical skirting board (7) is used. It is also possible to apply to acute corners or right angle corners. For example, as shown in FIG. 21, the wide-angle vertical skirting board (7) can be attached to a vertical vertical corner on the outer wall surface (11a) side of the first kick plate (31). That is, the wide-angle vertical skirting board (7) is joined to the one wall surface (11a) around the non-exposed side surface (78), and a part of the notch (72) corresponds to the first step plate (21). Place it so that it fits the tip. Specifically, the edge on the exposed side surface (77) side of the back surface (71a) of the nose-corresponding piece (71), that is, the rear edge of the exposed side surface (77) is used as the front end surface of the first step plate (21). While abutting, the edge on the non-exposed side surface (78) side of the back surface (71a), that is, the non-exposed side surface (78) side is arranged away from the front end surface of the first step plate (23). Further, the end face on the exposed side surface (77) side of the rear surface (79) of the kick-in part (75), that is, the rear end edge of the exposed side surface (77) is in contact with the surface of the first kick plate (31), An end edge of the rear surface (79) on the non-exposed side surface (78) side, that is, the non-exposed side surface (78) side is arranged away from the surface of the first kick plate (31). As a result, it is possible to attach the wide-angle vertical skirting board (7) to the vertical corner where the horizontal angle is a right angle. Further, in the same manner as described above, it is also possible to attach the wide-angle vertical skirting board (7) at the vertical corner where the horizontal angle is acute. However, the wide-angle vertical skirting board (7) has a more complicated structure than the narrow-angle vertical skirting board (6). Therefore, the narrow-angle vertical skirting board (6) having a simple structure is used as much as possible. Is preferred. Therefore, it is preferable to use a narrow-width vertical skirting board (6) at an acute angle or a right-angled vertical corner.

  In the above embodiment, a five-step staircase structure in which five staircases are attached to a staircase is described as an example. However, the present invention is not limited to this, and the present invention has two staircase steps and three steps.
