Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a handrail unit for stairs manufactured at a factory (handrails already assembled for stairs).

[0002]

2. Description of the Related Art Conventional stair handrails require difficult work to be processed on site. However, stair handrail units (handrails already assembled for stairs) are required to improve construction efficiency. From a viewpoint, it is manufactured in a factory in advance, and only needs to be attached to the stairs at the construction site.

However, stairs constructed on site have various inclination angles, and often do not coincide with the inclination angle of the handrail unit for stairs. Therefore, several types of handrail units for stairs that can cover a certain inclination angle are required, and adjustment work on the inclination angle is required at the construction site.

[0004]

[Problems to be solved by the invention] The present invention has been made in view of the above points, and its purpose is to
Easy installation and adjustment for stairs with different inclination angles
An object of the present invention is to provide a handrail unit for stairs which can be mounted and mounted .

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, a handrail unit for stairs according to the present invention has a bent portion near one end.
It erected a plurality of column members in the longitudinal direction of the formed comprising border If you install the handrail to the upper end of the pillar members co
In, over the entire length in the length direction of the ball leader on the back of the border, adjustment for mounting adjustment to the mounting stairs inclination angle
It has a configuration in which a nodal groove is formed .

[0006]

According to the handrail unit for stairs of the present invention, since the adjusting groove to be fitted to the upper edge of the side plate of the stairs is provided on the entire back surface of the border, the construction inclination angle of the stairs is reduced. If the inclination angle of the stair handrail unit is larger than the inclination angle of the unit and there is a deviation from the inclination angle of the handrail unit for stairs manufactured in advance, the lower the lower end of the border, the more the adjustment groove of the border. The adjustment groove of the border is fitted to the side plate of the stairs in a state where a gap is increased between the back surface of the stairs and the side plate of the stairs.

On the other hand, the construction inclination angle of the stairs is smaller than the inclination angle of the handrail unit for stairs, and there is a difference between the inclination angle of the handrail unit for stairs manufactured according to the design inclination angle of the stairs. If this occurs, as the upper end of the border goes all the way, the adjusting groove of the border is moved along the stairs in a state where the gap between the inner surface of the adjusting groove of the border and the side plate of the stairs is increased. Fit to side plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG .
Establishes the pillar 2 and the pillar 3 from the border 1,
A handrail 4 is fixed to these pillar members 2 and 3, and the border 1 and the handrail 4 are arranged so as to be parallel to each other. A border hanging portion 10 is fixed to the foot 2A of the main pillar 2.

[0009] The inclination angle Θ of each type of the border 1 is set so as to be compatible with any field angle.

As shown in FIG . 2, an inclined angle adjusting groove 5 is provided on the back surface of the border 1 over the entire length in the longitudinal direction of the border 1, and the inclined angle adjusting groove 5 has the same depth over the entire length. It is formed so that it can be fitted within a certain adjustment range on the upper edge B2 of the side plate B1 of the stairs B. The inclination angle adjusting groove 5 is shown in FIGS.
As shown in FIG. 5, one inclination angle adjusting groove 5A is for mounting the left side of the walled stairs B, and the other inclination angle adjusting groove 5B is for the right side mounting of the walled stairs B. ing.

The border hanging portion 10 also has a border 1
Adjustment groove 11 (11A, 1A)
1B) is formed.

There are a plurality of stair handrail units A having different inclination angles at intervals of 1 °, such as 43 °, 44 °, 45 °... 49 °, in accordance with the inclination angle of the stairs B. The stair handrail unit A corresponding to the inclination angle of the stairs B attached to the construction site is provided to the construction site.

However, since the site inclination angle α of the constructed stairs B has an error within a range of ± 0.5 ° with respect to the designed inclination angle of the stairs B, the stair handrail unit A is attached to the stairs B. In such a case, it is necessary to adjust the inclination angle, and the adjustment is performed as follows. That is,

When the construction angle α of the stairs B is larger than the inclination angle Θ of the handrail unit A for stairs, as shown in FIG. With the gap q between the back surface of the groove 5 and the side plate B1 of the staircase B increased, the inclination angle adjusting groove 5 of the border 1 is fitted to the side plate B1 of the staircase B.

When the construction angle α of the stairs B is smaller than the inclination angle Θ of the handrail unit A for stairs, as shown in FIG. The inclination angle adjusting groove 5 of the border 1 is fitted to the side plate B1 of the staircase B in a state where the gap q is reduced between the inner surface of the groove 5 and the side plate B1 of the staircase B.

When the inclination angle の of the handrail unit A for stairs and the construction angle α of the stairs B are the same, as shown in FIG. 5, the inclination angle adjusting groove 5 of the border 1 is provided without providing a gap q. the may be fitted to the side plate B 1 staircase B. In each case, the adjustment groove 11 is formed at the front edge B of the side plate B1 of the stairs B.
3 is fitted.

The stair handrail unit A attached to the stairs B in this way is supported and fixed by attaching the stairs B to the side plate B1 of the stairs B from the base materials C, D and the border 1.

FIG. 6 shows a state in which a handrail unit A for stairs is attached to a left side plate B1 of a staircase B having a right side plate B1 attached to a wall in the figure. In this case, an inclination angle adjusting groove is provided. 5B is filled with buried tree E. FIG .
Left side plate B of stairs B with left side plate B1 on the inside
FIG. 1 shows a state in which a stair handrail unit A is attached. In this case, the embedded tree E is packed in the inclination angle adjusting groove 5A.

F is a covering board.

[0020]

As is clear from the above description, according to the handrail unit for stairs of the present invention, the construction error of the inclination angle of the stairs is controlled by the adjusting groove of the border of the handrail unit for stairs. Therefore, the work of adjusting the mounting inclination angle becomes easy, and the on-site work time can be greatly reduced.
