BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stair handrail which can be easily attached to one or both sides of a stairway and has a good appearance after construction.

[0002]

2. Description of the Related Art Generally, one side or both sides of a staircase is fixed to a main pillar, and a lower end between the main pillars is fixed to the upper surface of the tread or both ends to a parent pillar, and is inclined at a predetermined distance from the tread. A handrail which is a rod fixed to a rail installed in a closed state, and a handrail which is fixed to the upper end of the handrail when the rail is present and is generally parallel to the rail. Very often there are stair railings. To construct a stair handrail with such a structure, whether the bottom end of the handrail is fixed directly upright to the tread or fixed to the rail by inclining with respect to the longitudinal direction of the rail, the handrail As a method of fixing the handrail to the upper end of the handrail, the upper end portion of the handrail child is fitted into a hole formed in the lower surface of the handrail, or a predetermined shape is applied to the plate body and this plate body. A plate-like body of a metal fixing metal fitting made of a cylindrical body protruding in a state of being inclined at an inclination angle is fixed to the lower surface of the handrail, and the upper end portion of the handrail is fitted to the cylindrical body. Either of the two methods was mainly adopted.

However, in the former method of fitting the upper end portion of the handrail into the hole formed in the lower surface of the handrail, the handrail is often installed in an inclined state at a predetermined position on the lower surface of the handrail. A hole for fitting the upper end of the handrail to the handrail must be accurately drilled at an angle that is oblique to the handrail. Since it is often different from the above, it requires work and skill because it is a site work, and even if a hole for fitting the upper end portion of such a handrail can be accurately drilled,
Since a large number of handrails must be fitted simultaneously on the lower surface of the handrail of the book, the work of fixing the handrail is very troublesome and requires skill. On the other hand, the latter method of using the fixing metal fitting is similar to the former method in that the plate-like body is fixed to the lower surface of the handrail after fitting the upper end portion of the handrail to the tubular body. There are no shortcomings,
Since the tubular body to which the handrail is fitted is exposed below the handrail, even if the handrail and the handrail are made of beautiful wooden materials, the exposed fixing metal fittings are made of metal. Since it is composed, the appearance is deteriorated and the inclination angle of the staircase is often different for each staircase, so it is made of metal with a different inclination angle to the plate according to the inclination angle of the staircase. It had the drawback of having to prepare a fixture.

Further, the handrail has its end face fixed to the side surface of the main pillar which is fixed upright on the tread of the stairs or the floor surface. The end surface of this handrail is fixed to the side surface of the main pillar. In order to secure a good appearance, the end of the handrail must be cut or machined at an angle to the longitudinal direction so that the end face of the handrail is in close contact with the side surface of the upright parent pillar. If the end face of the railing is cut or machined at a slightly different angle with respect to the longitudinal direction, a gap will be created between the end face of the handrail and the side face of the main pillar, and the appearance will be significantly reduced. Since the cutting or processing of the work must be done with great care, especially in this work, the inclination angle of the staircase is often different for each staircase, so it will be a site-matching work, so labor and high skill are required. There was a drawback that it required.

Further, the end of the handrail is fixed to the side surface of the main pillar. As a method of fixing the lower end of the handrail to the side surface of the main pillar, the end of the handrail is fixed. Part is provided with a protruding part and this protruding part is fitted into a hole formed in the side surface of the main pillar, or the end of the handrail is shaped to match the side surface of the main pillar, and the lower floor side of the handrail The method of driving the nail diagonally with respect to the longitudinal direction of the handrail from the hole formed in the lower surface near the end of the rail toward the side surface of the main pillar is widely adopted,
In the former method, it is necessary to form a hole in a predetermined position on the side surface of the main pillar with a shape that exactly matches the protrusion provided at the end of the handrail, and to align this direction. Since there are many cases where the stairs are different for each staircase, there is a disadvantage that it requires labor and high skill because it is a site-matching work. Further, the latter method has a drawback that the appearance is deteriorated when the hole for driving the nail remains exposed on the lower surface of the handrail.

Further, when the rails are installed between the main pillars in a state of being inclined at a predetermined distance from the tread plate, the end portions of the rails are fixed to the side surfaces of the main pillars as in the above-mentioned handrail. The end of the rail must be cut or machined diagonally to the longitudinal direction so that the end surface of the rail closely contacts the side surface of the upright parent pillar. If the cutting or machining angle is slightly different, a gap will be created between the rail end surface and the side surface of the main pillar and the appearance will be significantly deteriorated.Therefore, be careful when cutting or machining the rail end. This work also has a drawback that it requires a lot of manpower and a high degree of skill because the work is often done at different sites because the inclination angle of the stairs differs from stair to stair.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, does not require troublesome work and skill for fixing the handrail and the handrail, and is excellent from the outside. To fix the handrail and the handrail easily and in a good appearance without using a handrail or a member made of a completely different material from the handrail such as the above-mentioned fixing metal in the exposed position. It is an object to provide a stair handrail that can be used.

Further, with the above problems solved,
It is possible to easily fix the end of the handrail to the side surface of the main pillar without requiring troublesome work and skill to fix the end of the handrail to the side surface of the main pillar. Providing stair railings that can be done is also an issue.

Further, with the above problem solved,
Holes on the lower surface of the handrail to fix the lower floor end to the side of the main pillar expose the lower surface of the rail to expose the lower surface of the handrail. It is also an issue to provide a stair railing that eliminates the drawback of doing.

Further, with the above problem solved,
When the rails are installed between the main pillars with a certain distance from the treads, fixing the end of the rail to the side surface of the main pillar does not require troublesome work and skill, and is easy. Moreover, it is another object to provide a stair handrail that can fix the end of the rail to the side surface of the main pillar in a state in which the appearance is good.

[0011]

Means for Solving the Problems As a result of earnest research to solve the above problems, the present inventor did not require troublesome work and skill to fix the handrail and the handrail member, To fix the handrail and the handrail easily and in a good appearance without using a member that is made of a completely different material from the handrail or the handrail and that is exposed in a position that is easily visible from the outside. A groove with a constant width is formed along the entire length of the lower surface of the handrail, and a handrail upper surface fixing plate mounted and fixed on the upper surface of the adjacent handrail is fitted into this groove. I've figured out what to do.

When the end of the handrail is fixed to the side surface of the main pillar, even if the angle at which the end of the handrail is cut or machined with respect to the longitudinal direction of the handrail is slightly different, the pillar of the main post is formed. A groove with a constant width is formed over the entire length of the side surface of the handrail fixed side of the part,
If the structure is such that the end face of the handrail is fitted into this groove, at least only the upper end face of the handrail does not have a gap between the side face of the main pillar and the appearance does not deteriorate. By forming a groove with a constant width along the entire length of the side surface of the main pillar on the side where the handrail is fixed, the pillar is exposed at the upper end of the main pillar pillar and the appearance is degraded. The protrusions that are provided from the lower surface of the decorative top that extends outward from the pillar to the engaging portions such as holes (screw holes may be used) and protrusions (screws may be used) provided on the top of the It has been clarified that this can be solved by adopting a structure in which an engaging portion such as a screw portion) or a hole (a screw hole may be used) is engaged.

Further, in order to fix the lower floor side end of the handrail to the side surface of the main pillar, a nail driving hole is formed in the lower surface near the lower floor end of the handrail. The drawback that the hole for nailing is exposed on the lower surface of the handrail and the appearance deteriorates,
The lower surface of the handrail near the lower floor end closes the lower surface of the handrail near the lower floor end, concealing the nailing hole, and the upper surface of the handrail at the lower surface of the handrail. It was also clarified that the concealing plate that is continuous with the fixing plate may be fixed.

When a rail to which the lower end of the handrail is fixed is installed between the main pillars in a state of being inclined at a predetermined distance from the tread plate, the end of the rail is fixed like the above-mentioned handrail. Even if the angle of cutting or processing the end of the rail with respect to the longitudinal direction for fixing to the side surface of the main pillar is slightly different,
If the structure is such that the end of the rail is fitted in the groove formed over the entire length of the side surface on the handrail fixed side of the main pillar, at least only the upper end of the rail will be between the side surface of the main pillar. It was also clarified that the appearance is not deteriorated by preventing the formation of the gap.

[0021]

In order to construct the stair handrail according to the present invention by using the above-mentioned components, first, the floor surface 1 or the tread plate on the lower floor of the building is constructed.
First step tread 2a of stair 2 consisting of 2a and riser 2b
Then, the lower end portion of the main pillar 3 is fixed to the step plate 2a in the middle of the stairs 2 or the floor surface 1 of the upper floor at a predetermined position on one side or both sides of the stairs 2. This fixing method may be a conventionally known fixing method.
Next, when the rails 5 are installed between the main pillars 3 and inclined from the treads 2a of the stairs 2 by a predetermined distance, both ends of the rails 5 are fixed to the main pillars 3, respectively. At this time, if a groove 3b having a constant width is formed along the entire length of the side surface of the pillar 3a of the main pillar 3 on the side where the handrail 6 is fixed, the end of the rail 5 is fixed to the pillar 3a of the main pillar 3. When fitted into the groove 3b formed over the entire length of the handrail fixed side surface, the upper and lower edges of the rail 5 can be seen from above and below when viewed along the groove 3b, but the left and right edges are defined by the groove 3b. Since it becomes invisible, it is most problematic if there is a gap in appearance. The side surface of the main pillar 3 on which the handrail is fixed and the upper end of the rail 5 are in contact with each other without a gap. In this case, a slight gap may be formed between the end portion of the rail 5 and the pillar portion 3a of the parent pillar 3 in the left-right direction or below.

After this, the rail 5 is installed in a state where the lower end of the handrail 4 is inclined between the treads 2a of the stairs 2 or between the main pillars 3 and at a predetermined distance from the treads 2a of the stairs 2. In some cases, after fixing to each of these rails 5 (rail 5
, The lower end of the handrail 4 may be fixed to the rail 5 in advance), and the upper surface of the adjacent handrail 4 at the same angle as the handrail 6 is attached. The handrail upper surface fixing plate 7 is placed on the upper end 4a of the handrail 4 which is formed so that the line connecting them forms one plane, and the handrail upper surface fixing plate 7 and the handrail are mounted by means such as nailing. Child 4
Fix and. At this time, when the concealing plate 8 to be described later is used, the portion of the handrail upper surface fixing plate 7 adjacent to the lower post side pillar 3 is shorter by the length thereof.

Next, both ends of the handrail 6 are attached to the pillar portion 3a of the parent pillar 3.
The handrail upper surface fixing plate 7 is fitted in the groove 6a having a constant width, which is in contact with the side surface of the handrail fixed side and is formed over the entire length of the lower surface thereof. At this time, the pillar portion 3a of the parent pillar 3
When the groove 3b having a constant width is formed along the entire length of the side surface of the handrail fixed side, the end portion of the handrail 6 extends over the entire side surface of the pillar portion 3a of the main pillar 3 on the side where the handrail 6 is fixed. When fitted in the groove 3b provided, the upper and lower edges of the handrail 6 can be seen from above and below when viewed along the groove 3b, but the left and right edges cannot be seen by the groove 3b. The outer side of the handrail 6 is the most problematic when there is a gap in appearance. If the side face of the main pillar 3a on which the handrail is fixed and the upper end of the handrail 6 are in contact with each other without any gap, the end of the handrail 6 A slight gap may be formed between the edge of the parent pillar 3 and the pillar portion 3a of the parent pillar 3 in the left-right direction or in the lower direction.

On the lower surface of the handrail 6 near the lower floor end, a nail driving hole 6b for fixing the lower floor end to the side surface of the main pillar 3 is formed. With the end of the lower floor side abutting the side surface of the main pillar 3, tilting the nail 6c into the main pillar 3 from the nailing hole 6b with the handrail 6 inclined with respect to the longitudinal direction of the handrail 6. When fixing the railing 6 and the main pillar 3, the nailing hole 6b exposed on the lower surface near the lower floor side end of the handrail 6 is concealed and the lower surface of the handrail 6 is covered. If the concealing plate 8 is fixed to the lower surface of the handrail 6 so as to be continuous with the upper surface fixing plate 7 of the slider, the main pillar 3 is provided below the edge of the handrail 6.
There is no problem even if a large gap is formed between the column portion 3a and the column portion 3a.

Thus, both ends of the handrail 6 are provided with the pillar portions of the parent pillar 3.
After the handrail upper surface fixing plate 7 is fitted into the groove 6a having a constant width, which is in contact with the side surface of the handrail fixed side of 3a and is formed over the entire length of the lower surface thereof, the main pillar 3 When a groove 3b having a constant width is formed along the entire length of the side surface of the pillar portion 3a on the side where the handrail is fixed, the pillar portion is formed on the engaging portion 3c provided on the top portion of the pillar portion 3a of the parent pillar 3. When the engaging portion 3e provided on the lower surface of the decorative top portion 3d extending outward from the 3a is engaged and fixed, at least a groove formed at least on the handrail 6 fixed side of the pillar portion 3a of the parent pillar 3. It is possible to prevent the external appearance of the main pillar 3 from being significantly deteriorated by exposing the top portion of the pillar portion 3a to the 3b.

[0026]

As described above in detail, the stair handrail according to the present invention is placed on the upper surface of the handrail adjacent to the groove of a constant width formed over the entire length of the lower surface of the handrail. Since the structure is such that the fixed handrail upper surface fixing plate is fitted, place the handrail upper surface fixing plate on the upper surface of the handrail and place the handrail upper surface fixing plate by means such as nailing. After fixing to the upper surface of the handrail, the handrail is fixed to the upper plate of the handrail by fitting a groove of a constant width formed along the entire length of the lower surface of the handrail to the upper end of the handrail. It can be easily and easily fixed in a good appearance.

When a groove having a constant width is formed over the entire length of the side surface of the main pillar on the side where the handrail is fixed, and the end portion of the handrail is fitted in the groove having the constant width. Is designed so that no gap is formed between at least the upper end face of the handrail and the side face of the main pillar even if the angle at which the end of the handrail is cut or machined with respect to the longitudinal direction of the handrail is slightly different. For example, the slight gaps to the left and right of the end face of the handrail are hidden by the side walls of the groove of a constant width that is drilled over the entire length of the side face of the main pillar on the side where the handrail is fixed. It is difficult for the appearance to deteriorate due to the difference in the angle of cutting or processing with respect to the longitudinal direction, and by forming a groove of a constant width over the entire length of the side surface on the handrail fixed side of the pillar portion of the main pillar. Providing that the groove is exposed at the upper end of the pillar of the main pillar and the appearance deteriorates is provided on the top of the pillar of the main pillar. Than it can be eliminated by the structure to engage the engagement portion provided on the lower surface of the decorative top to overhang outside the pillar portion in the engaging portion being. Also,
By forming a groove with a constant width along the entire length of the side surface of the main pillar on the handrail fixed side, the angle at which the end of the handrail is cut or machined with respect to the longitudinal direction of the handrail is slightly different. If there is a gap between the upper end of the handrail and the side surface of the main pillar, the width is the same as the width of the constant width groove that is drilled over the entire length of the side surface of the main pillar pillar on the side where the handrail is fixed. Is thinner than the depth of the groove, but thicker than the gap between the upper edge of the handrail and the side surface of the main pillar, and a plate material of the same material as the main pillar is used to connect the pillar to the main pillar. By fitting from the upper part of the rail fixing part to the upper end of the pillar part of the parent pillar, it is possible to hide the gap between the upper end surface of the handrail and the side surface of the parent pillar without lowering the appearance. is there.

Further, in the case where a hole for nailing is formed in the lower surface near the end on the lower floor side of the handrail in order to fix the end on the lower floor side of the handrail to the side surface of the main pillar. If this hole for nailing is concealed and a concealing plate that is continuous with the handrail upper surface fixing plate is fixed on the lower surface of the handrail, the nailing hole is exposed on the lower surface of the handrail and the appearance deteriorates. The disadvantage of doing so can also be prevented.

Further, when a rail to which the lower end of the handrail is fixed is installed between the main pillars at a predetermined distance from the tread plate, the end of the rail is fixed to the side surface of the main pillar. However, like the above-mentioned handrail, if the structure is such that the end of the rail is fitted into the groove formed over the entire length of the handrail fixed side surface of the pillar of the main pillar, the end of the rail will be Even if there is a slight difference in the angle at which the end of the rail is cut or machined with respect to the longitudinal direction to fix it to the side surface of the main pillar, at least only the upper end of the rail end surface does not have a gap with the side surface of the main pillar. Therefore, the appearance does not deteriorate.

The stair handrail according to the present invention having such various effects has a great industrial value.
