A large number of vertical lattices 5 extending in the vertical direction are fixed between the upper rail 3 and the lower rail 4. The upper end of the upper rail 3 is fitted into a mortise hole 8 formed in the side surface near the upper end of the main pillar 6 above the stairs 1, and then fixed by a screw 9. The lower end of the upper rail 3 is fitted into a mortise hole (not shown) formed in the side surface near the upper end of the main pillar 7 below the stairs 1. The lower rail 4 is fixed to the inclined side edge portion 11 of the stairs 1, and the upper and lower ends of the lower rail 4 are fixed to the side surfaces of the main posts 6 and 7. Upper and lower bars 3, 4
And the vertical grid 5 between them is preassembled.

The upper end surface 10a of the headstock 10 is inclined along the side surface of the main pillar 6, and the upper end surface 10a of the headboard 10 is inclined.
The side surface of the main pillar 6 can be closely attached. The lower end of the headstock 10 is fixed to the upper end of the main pillar 7. Kasaki 10
An elongated groove for fitting the upper rail 3 is formed on the lower surface of the upper rail 3, and the upper rail 3 is covered with the headstock 10 so that it cannot be seen from the upper side and the side.

As shown in FIG. 1, a recess 13 for mounting the decorative plate 12 is provided on the surface of the main pillar 6 on the opposite side of the mortise 8 at the top of the stairs. A pair of screw holes 15 through which the screws 14 as screwing means are inserted are formed. The pair of screw holes 15 and 15 extend at right angles to the upper end surface 10 a of the headstock 10. The tip end of the screw hole 15 on the headstock 10 side is formed thin so that the screw 14 is screwed, and the head flange of the screw 14 abuts and stops, and the portion of the screw hole 15 on the recess 13 side is screwed. It has a slightly large diameter opening so that 14 head flanges can be passed through.

The handrail 2 for stairs is assembled as follows.

First, the main pillars 6 and 7 are erected above and below the stairs 1,
A combination of vertical grids 5 between the upper and lower crosspieces 3 and 4 is attached to the side edge portion 11 of the stairs 1. At this time, as described above, the upper and lower end portions of the upper rail 3 and the lower rail 4 are fitted into the mortise holes of the main posts 6 and 7, and the screw 9 is attached to the upper end portion of the upper rail 3 fitted in the mortise hole 8. The upper rail 3 and the lower rail 4 are fixed to the side edge portion 11 of the staircase 1 by screwing in from an oblique direction. After fixing the upper rail 3 to the main pillars 6 and 7, a screw is screwed onto the side edge portion 11 of the stairs 1 from above the lower rail 4, and the top of the screw is covered with a decorative plate (not shown). The upper rail 3 is fitted into the groove of 10. Kasaki 10
When fitting the upper rail 3 into the groove of the
0a is closely attached to the side surface of the main pillar 6. After the headstock 3 is fitted to the upper rail 3, the screws 14 are screwed into the pair of screw holes 15 of the main pillar 6, respectively, and the main pillar 6 and the upper end surface 10a of the main pillar 10 are screwed together. When the upper end surface 10a of the headstock 10 is fixed to the main pillar 6, the lower end of the headstock 10 is fixed to the main pillar 7, and the decorative plate 12 is fitted and fixed in the recess 13 of the main pillar 6.

The stair handrail 2 according to the present embodiment includes an upper rail 3
The upper end of the upper pillar 3 is fitted in the mortise 8 of the main pillar 6, and a screw 9 is obliquely screwed onto the upper end of the upper bar 3, and the upper bar is inserted in the groove on the lower surface of the head tree 10 in which the upper end surface 10a is inclined. 3 is fitted, the upper end face 10a of the headstock 10 is brought into close contact with the side wall of the main pillar 6, and the screw 14 is screwed from the main pillar 6 to the headwood 10 side. Therefore, the headwood 10 and the main pillar 6 are pulled from each other. As a result, the upper end face 10a of the headstock 10 and the main pillar 6 are firmly adhered to each other without a gap, the upper rail 3 is not exposed, and a screw 14 is screwed from the main pillar 6 side to the headstock 10 side. Therefore, the decorativeness of the head tree 10 itself is not impaired. In addition, since the screws 14 are screwed together, even if a force that pulls the head tree 10 and the main pillar 6 off is applied, the resistance of the screw thread of the screw 14 makes the head tree 10 and the main pillar 6 very much. It is firmly fixed for a long period of time, and the strength of the staircase handrail 2 itself can be improved. In addition, even if the screw 14 is removed and the headstock 10 or the main pillar 6 is replaced, the headstock 10 and the main pillar 6 can be firmly fixed again by screwing the screw 14 again.

Although the screw 14 is used as the screwing means in the above embodiment, the present invention is not limited to this, and a female screw member (for example, a nut) is embedded in the upper end face 10a side of the headstock 10 to form the main pillar 6 side. Alternatively, a male screw (for example, a bolt) may be provided to fix the male screw and the female screw.
