Description

【０００１】
【発明の属する技術分野】
本発明は階段の手摺構成材に関する。
【０００２】
【従来の技術】
従来、この種の階段の手摺構成材として以下の如きものは知られている。即ち、親柱と、手摺とを有しており、施工現場の階段の傾斜に対応してその施工現場で親柱にほぞ孔を形成すると共に手摺の端部に前記ほぞ孔に整合・嵌合するほぞを形成した後、施工するようにしたものは知られている。
【０００３】
【従来技術の欠点】
前記従来の階段の手摺構成材には以下の如き欠点があった。即ち、施工現場で親柱にほぞ孔を形成すると共に手摺の端部に前記ほぞ孔に整合・嵌合するほぞを形成するものであったため、施工効率が悪く、また、現場の作業員の熟練度によって出来栄え（納まり具合）に差が出るという欠点があった。
【０００４】
【課題を解決するための手段】
本発明は前記欠点を解消するために以下の如き手段を採用した。
請求項１の発明は、上部に奥部に行くほど上下方向に拡がった手摺嵌合孔が設けられた親柱と、該親柱の前記手摺嵌合孔の開口縁に、左右側面が当接した状態で嵌められ、前記開口縁を支点として上下揺動され、傾斜角度を調節された上で固定するようになされた手摺とを有し、前記手摺の端部が側面から見て先細となる形状をしており、前記手摺の端部が前記手摺嵌合孔に上下位置変更自在に所定の傾斜角度に調節して嵌められるように構成されているものである。
請求項２の発明は、請求項１の発明において、前記手摺の端部が、前記手摺嵌合孔の上下の開口縁に密接又はほぼ密接するように構成されているものである。
【０００５】
【発明の作用】
請求項１の発明は以下の如き作用をなすものである。施工現場で何らの加工・製作も行なうことなく、手摺の傾斜を施工現場の階段に対応したものとすることが出来る。請求項２の発明は、請求項１の発明に加えて、手摺の端部と手摺嵌合孔の開口縁とが密接又はほぼ密接状態を保つので、手摺と手摺嵌合孔の開口縁との納まりがよい。
【０００６】
【発明の実施の形態】
以下に、４つの、発明の実施の形態を図面を参照しつつ説明する。
なお、これらの説明において同一の部材は同一の符号で示す。

[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, four embodiments of the invention will be described with reference to the drawings.
In these descriptions, the same members are denoted by the same reference numerals.
[0007]
[First Embodiment of the Invention] (See FIGS. 1 and 2)
In this description, “front” refers to the left side of FIG. 1, “rear” refers to the right side, “left” refers to the front side of FIG. 1, and “right” refers to the back side.
[0008]
The handrail component 1 of the staircase includes a main pillar 3 (on the lower floor of the staircase) in which a handrail fitting hole 2 that expands in the vertical direction toward the back is formed in the upper part, and a handrail fit of the main pillar 3 And a handrail 5 which is fitted in the joint hole 2 and swings up and down with the upper and lower opening edges 2a of the handrail fitting hole 2 as fulcrums.
[0009]
The handrail 5 has a reference inclination angle of 43 °, and can swing about 7 ° upward and downward from this angle. In addition, an inclination angle means the angle seen from the side surface which the horizontal line and the centerline of the handrail 5 make.
The handrail fitting hole 2 that expands in the vertical direction as it goes to the inner part refers to a hole that expands in the vertical direction toward the inner part so that the handrail 5 can swing up and down within a predetermined range. Therefore, if the handrail 5 is a handrail fitting hole 2 that can swing up and down within a predetermined range, even if the vicinity of the back is narrowed up and down, the handrail fitting hole that expands in the vertical direction as the vicinity of the opening edge goes to the back. If it is 2, it is the handrail fitting hole 2 which spreads in the up-down direction as it goes to the inner part in this specification.
[0010]
The handrail 5 is squeezed by the upper and lower opening edges 2a (which are in contact with or substantially in contact with the upper and lower side surfaces of the handrail 5). As shown in FIG. Note that the left and right side surfaces of the handrail 5 are in close or close contact with the left and right side surfaces of the handrail fitting hole 2. That is, the handrail 5 cannot move left and right within the handrail fitting hole 2.
[0011]
The handrail fitting hole 2 is formed from the front corner of the main pillar 3 toward the rear.
[0012]
After completion of the construction, the handrail 5 is fixed to the main pillar 3 by a known fixing means such as a screw, a nail, or an adhesive.
[0013]
[Second Embodiment of the Invention] (See FIGS. 3 and 4)
The main pillar 3 has an ornamental quadrangular pyramid portion 10 in the form of a top portion removed from the upper part, and the main pillar 3 is viewed from the front inclined surface of the ornamental quadrangular pyramid portion 10 (the front means the left side in FIG. 3). A handrail fitting hole 2 is formed in 3.
[0014]
[Third Embodiment of the Invention] (See FIGS. 5 and 6)
In this description, “front” means the left side of FIG. 5 and “rear” means the right side of FIG.
The handrail fitting hole 2 is formed from the front side surface of the main pillar 3 toward the rear.
By forming a handrail fitting hole 22 opened rearward as shown by the two-dot chain line in FIG. 5 in the main pillar 3 not forming the handrail fitting hole 2, it is connected to the main pillar 3 on the upper floor of the stairs. I can do it.
1 and the main pillar 3 shown in FIG. 3 (without the handrail fitting hole 2) or the handrail fitting hole 22 in the main pillar 3 shown in FIG. 3 (without the handrail fitting hole 2). Of course, they can be used as the main pillar 3 on the upper floor of the stairs.
[0015]
[Fourth Embodiment of the Invention] (See FIGS. 7 and 8)
In this description, “front” refers to the left side of FIG. 7, “rear” refers to the same right side, “left” refers to the front side of FIG. 7, and “right” refers to the back side.
[0016]
The handrail component 1 of the staircase includes a main pillar 3 (on the lower floor of the staircase) in which a handrail fitting hole 2 that expands in the vertical direction toward the back is formed in the upper part, and a handrail fit of the main pillar 3 And a handrail 5 having an end portion 5a that is fitted in the joint hole 2 so that the vertical position can be freely changed.
The end 5a of the handrail 5 has a tapered shape when viewed from the side, and the end 5a is fitted into the handrail fitting hole 2 with the handrail 5 in a predetermined inclined state (inclination angle 0 ° to 50 °). By inserting, the end portion 5a is brought into close or almost close contact with the upper and lower opening edges 2a of the handrail fitting hole 2.
Note that the left and right side surfaces of the handrail 5 are in close or close contact with the left and right side surfaces of the handrail fitting hole 2. That is, the handrail 5 cannot move left and right within the handrail fitting hole 2.
By forming a handrail fitting hole 22 that opens rearward as shown by a two-dot chain line in FIG. 7 in the main pillar 3 that does not form the handrail fitting hole 2, it is connected to the main pillar 3 on the upper floor of the stairs. I can do it.
[0017]
[Modifications]
A description will be given below of modifications and the like.
(1) A handrail or the like is attached to the handrail 5 by a known method.
(2) The fixing of the lower end of the main pillar 3 to the floor surface or the tread is performed by a known means.
(3) The shape of the handrail fitting hole 2 is not limited to that illustrated. Moreover, the cross-sectional shape of the handrail 5 is not limited to a rectangle.
[0018]
【The invention's effect】
The present invention has the following effects by the configuration as described above.
(1) According to the first aspect of the present invention, the inclination of the handrail can be made to correspond to the stairs on the construction site without performing any processing / production at the construction site .
(2) According to the invention of claim 2, it is possible to make the inclination of the handrail correspond to the stairs of the construction site without performing any processing / manufacturing at the construction site. Since the opening edge of the fitting hole is in close contact or almost in close contact with the opening, the handrail and the opening edge of the handrail fitting hole are well accommodated.
