BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail structure attached to an open staircase of a house or the like.

[0002]

2. Description of the Related Art As shown in FIG.
As in the handrail described in Japanese Patent Publication No. 33, a rotatable mounting tool 22 is fixed to the lower part of the upper horizontal member 20 and the upper part of the lower horizontal member 21, and a stretchable handrail between the mounting members 22. 23
It has been disclosed that the. Unlike the handrail 23 for stairs, the handrail 24 is a handrail 24 to be installed on a slope for the exterior. Therefore, even if the mounting position of the handrail 24 is an inclined surface,
The height of the handrail 23 can be changed by the rotatable mounting tool 22, and the mounting height of the handrail 24 can be freely changed. At this time, since the pin 25 at the rotation fulcrum of the rotatable fixture 22 can be seen from the outside,
There was a problem that the finished appearance was poor.

However, like the stairs in the interior of a house, the handrail 23 is kept at a constant height and the handrail 2
3 and a handrail structure capable of easily constructing the handrail 24 according to the inclination angle of the stairs.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and the connection between the handrail and the upper end of the handrail becomes variable according to the inclination angle of the stairs, and the screw head is outward. It provides a handrail structure that is simple in construction without protruding to the outside and has a good appearance.

[0005]

The handrail structure according to claim 1 of the present invention comprises a plurality of handrails which are erected on a tread and an inclined surface formed at the tip of the handrail, and the inclined surface is formed on the inclined surface. A handrail fixing part of a handrail mounting fixture including a handrail fixing part and a rotatable handrail inserting part is fixed, and a handrail to which the handrail inserting part of the handrail mounting part is attached is fixed. It is a thing.

Therefore, since the connection between the handrail and the upper end of the handrail can be changed in accordance with the inclination angle of the stairs, the construction is simple and the screw head does not project outward, and the appearance is good.

According to a second aspect of the present invention, the width of the handrail attachment according to the first aspect of the present invention is made smaller than the width of the inclined surface of the tip of the handrail and the rotatable handrail insertion portion is a plate. It is characterized in that it is formed into a shape and the handrail insertion portion is inserted into the groove portion of the handrail.

Therefore, the turning range of the handrail attachment can be set large by the inclined surface of the handrail tip. or,
The rotatable handrail insertion part can be inserted into the groove of the handrail, and the handrail mounting tool can be inserted inside the handrail, so the rotating part cannot be seen from the outside and construction is simple. .

In the handrail structure according to claim 3 of the present invention, a lower wide two-step groove is formed inside the handrail according to claim 1 or 2, and the width of the upper groove is attached to the handrail. The width of the tool is substantially the same, and the upper ends of the handrails are covered with both side ends of the lower groove.

Therefore, since the upper end portions of the handrail fitting and the handrail are covered by the two-step groove portions inside the handrail, the appearance is improved.

According to a fourth aspect of the present invention, there is provided a handrail structure according to any one of the first to third aspects, in which the handrail fixing portion of the handrail attachment is fixed to the inclined surface of the tip of the handrail. The handrail insertion portion is inserted into the groove portion above the handrail, and the blindfold plate is inserted into the groove portion below the handrail.

Therefore, the inside of the handrail fitting or the handrail cannot be seen from the lower part of the handrail, so that the appearance is good.

At this time, the width W2 of the handrail attachment 6 is formed to be smaller than the width W3 of the inclined surface 3 at the tip of the handrail 2 and the rotatable handrail insertion portion 5 is formed in a plate shape. 5 is inserted into the groove 12 on the upper stage of the handrail 7.

At this time, upper and lower two-tiered groove portions 12, 13 having a wide lower width W1 are formed inside the handrail 7 made of wood, plastic, stainless steel or the like having a dome-shaped cross section,
The width W1 of the lower groove portion 13 is the width W1 of the handrail mounting tool 6.
And the upper end of the handrail 2 is covered with the both side ends of the lower groove portion 13.

The width W3 of the handrail 2 is 7
It is formed substantially the same or slightly smaller so that it can be rotated so that it can be inserted into the lower groove portion 13.

Further, the handrail fixing portion 4 of the handrail attachment 6 is fixed to the inclined surface 3 at the tip of the handrail 2, the handrail insertion portion 5 is inserted into the groove 12 at the upper portion of the handrail 7, and the handrail 7 is provided. A rectangular blindfold plate 14 having a width W1 is inserted in the groove 13 at the bottom of the. With this blindfold plate 14,
Since it is possible to blindfold a plurality of handrails 2, 2, the appearance becomes good.

The mounting state of the handrail structure A according to one embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1, 2 and 7, the handrail structure A has a plurality of handrails 2 arranged upright on a step board 1 of a staircase, and a lower end portion 15 of the handrail 2 is disposed. Are fastened to the tread 1 with bolts or nails. Then, as shown in FIG. 5, the handrail fixing portion 4 is attached to the inclined surface 3 at the tip of the handrail 2.
And a handrail mounting tool 6 including a rotatable handrail insertion portion 5
The handrail fixing part 4 is fixed.

As shown in FIG. 3, the handrail fitting 6
A rotatably mounted bolt 11 is fixed below the bearing portion 9 of FIG. Then, the handrail insertion portion 5 of the handrail attachment 6 is adapted to rotate. The handrail insertion portion 5 is suspended, and the bolt 11 is screwed to the inclined surface 3 of the handrail 2. The plate part (width W2) of the handrail insertion part 5 is
As shown in FIG. 4, a lower groove portion 13 is provided inside the handrail 7.
A width W2 of the upper groove portion 12 having a large width W1 is formed, and the width W1 of the upper groove portion 12 is fitted to a plate body portion formed to be substantially the same as the width W2 of the upper groove portion 12.

At this time, the length of the handrail 7 is 2000-
It is about 4500 mm and can be rotated. Then, the width W1 of the lower groove portion 13 is formed so that the upper end portion of the handrail 2 is covered. The handrail 2 is made of wood, plastic, stainless steel or the like having a quadrangular cross section, forms a slanted surface 3 by cutting the tip at an angle of 30 to 60 degrees, and has a height of 900 to 1100 mm and a cross section. The size is about 30 to 60 mm. The shape of the handrail 2 may be a rhombus or a round shape in cross section. The groove heights H1 and H2 of the upper groove 12 and the lower groove 13
Is about 10 to 20 mm and the total height is 30 to 60 mm
It is a degree. Especially, if the appearance shape is set, the upper groove 1
The handrail mounting tool 6 may be inserted into the groove portion 2 and the lower groove portion 13.

The handrail attachment 6 fixed to the tip of the handrail 2 comprises a handrail fixing portion 4 and a rotatable handrail insertion portion 5. The handrail insertion portion 5 is formed by forming a hanging piece 8 at the center of the back surface of a rectangular plate body, and the handrail fixing portion 4 is substantially U into which the hanging piece 8 of the handrail insertion portion 5 is inserted. A letter-shaped bearing portion 9 is formed, and the hanging piece 8 and the bearing portion 9 are rotatably fixed via a pin 10. This rotating mechanism is only required to insert the plate body of the handrail insertion portion 5 into the groove 12 in the upper stage of the handrail 7 with an adhesive, screws, or the like.

At this time, the width W3 of the handrail 2 is formed to be substantially the same or slightly smaller so that it can be inserted into the lower groove portion 13 of the handrail 7 and can be rotated.
