Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for handrail members.

[0002]

2. Description of the Related Art For example, handrails are generally provided on stairs and corridors of houses. How to design handrails, especially when elderly people and people with disabilities are included as residents. Is one of the important things when designing a house. Conventionally,
Such a handrail is configured by disposing a plurality of support brackets on a wall surface such as a staircase portion, fixing a handrail member to an upper end portion of the support bracket, and attaching the handrail member along the stairway portion. The mounting height of is determined from the viewpoint of ergonomics, and is set to a certain height according to the national average height.

[0003]

However, since the conventional support bracket is a completely fixed type, it is not possible to easily adjust its height to the height difference and growth of individuals.
Therefore, when it is found out that the mounting height of the handrail member does not conform to the actual resident after the construction of the house, it is necessary to newly replace the support bracket with another height.

In view of such circumstances, it is an object of the present invention to provide a supporting structure for a handrail member which can easily adjust the height of the handrail member without replacing the support bracket.

[0005]

[Means for Solving the Problems] In order to achieve the above object,
The technical means taken by the present invention is that a height adjusting means for adjusting the supporting height of the handrail member is provided between the handrail member and the support member supporting the handrail member.

[0006]

The height adjusting means is provided between the handrail member and the support member for supporting the handrail member. Since the height of the handrail member can be adjusted by this means, the handrail member can be mounted after the handrail member is attached. Even if you want to change the mounting height of
It is not necessary to replace the support bracket 3 newly.

[0007]

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 3 show a first embodiment of the present invention. In the figure, a handrail 1 according to the present embodiment has a plurality of support brackets attached to an interior plate 2 that constitutes a staircase or a corridor of a house.
3, a long handrail member 4 is fixed to the upper end of the support bracket 3, and the handrail member 4 is attached along the interior plate 2.

The support bracket 3 is made of a metal material such as steel, and is integrally provided with a flat plate-shaped mounting plate portion 5 and an L-shaped support arm 6 projecting from the mounting plate portion 5,
Screw the four corners of the mounting plate 5 to the interior plate 2 via the spacers 7a.
7 By fixing it, it is fixed in place on the interior plate 2. The tip of the support arm 6 also has a vertical screw hole.
A tubular portion 9 having an inner portion 8 is provided.

The handrail member 4 is made of a long wooden member having a circular cross section, and is provided with bottomed insertion holes 10 extending downward in the radial direction from the center of the cross section at regular intervals in the longitudinal direction. Into the tubular portion 9 of the support bracket 3, a retractable shaft 12 having a lower half with a screw portion 11 screwed into the screw hole 8 of the tubular portion 9 is inserted, and the axial center portion of the retractable shaft 12 is inserted. A tool engagement hole 13 that penetrates in the axial direction is provided.

In this embodiment, by supporting the handrail member 4 from the lower side by the push-out shaft 12, the handrail member 4 is adjusted between the handrail member 4 and the support bracket 3 in height. The height adjusting means 14 for this is configured. That is, the handrail member 4 has a structure in which the upper half of the retractable shaft 12 is a handrail member.
It is supported by the support bracket 3 by being inserted freely into the insertion hole 10 of 4, and the hexagon wrench 15 or the like is inserted into the engaging hole 13 of the retractable shaft 12, and the retractable shaft 12 is rotated to retract. The amount of protrusion of the shaft 12 with respect to the tubular portion 9 changes, whereby the support height of the handrail member 4 can be adjusted without changing the mounting height of the support bracket 3.

In addition, the handrail member 4 has an insertion hole 10 at the side of its cross section.
A metal cylindrical body 16 communicating with is embedded in this cylindrical body 16, and a first stopper screw 17 for restricting relative rotation of the retractable shaft 12 and the handrail member 4 is screwed into the cylindrical body 16. Further, a second stopper screw 17a for restricting relative rotation between the tubular portion 9 and the retractable shaft 12 is screwed into the tubular portion 9 of the support bracket 3. As shown in FIG. 3, the handrail 1 according to the present embodiment can be mounted on the head tree 19 of the waist wall 18 by adopting the support bracket 3 having the columnar support arm 6.

FIG. 4 shows a second embodiment of the present invention. The difference of this embodiment from the first embodiment is that instead of the retractable shaft 12 in the first embodiment, a reverse screw shaft 22 having upper and lower screw portions 20, 21 whose screw groove directions are opposite to each other is adopted. is there. That is, in this embodiment, the lower screw portion 21 of the reverse screw shaft 22 is
To adjust the support height of the handrail member 4 by screwing the upper screw portion 20 into the metal tubular body 23 embedded in the lower portion of the handrail member 4 while screwing the screw into the tubular portion 9 of the support bracket 3. The height adjusting means 14 is configured.

The relative rotation between the reverse screw shaft 22, the handrail member 4 and the support bracket 3 is restricted by a lock nut 24 fitted on the reverse screw shaft 22. Further, in the present embodiment, the engaging groove 25 of the hexagon wrench 15 is formed at the lower end of the counter screw shaft 22, and the vertical hole 26 communicating with this engaging groove 25 is provided with the support bracket 3.
Therefore, the reverse screw shaft 22 can be rotated by the hexagonal wrench 15 inserted from below the vertical hole 26.

Next, FIGS. 5 and 6 show a third embodiment of the present invention. In this embodiment, instead of the second stopper screw 17a for restricting the relative rotation between the tubular portion 9 of the support bracket 3 and the retractable shaft 12, the tip end portion of the tubular portion 9 is pinched in the radial direction. The tightening body 27 is screwed onto the retractable shaft 12. That is, as shown in FIG. 6, the tubular portion 9 includes a tapered taper surface 27 formed on the outer periphery of the tip thereof and four holding pieces 29 arranged in the circumferential direction through a notch 28 extending axially downward from the tip. On the other hand, on the other hand, a tapered inner surface 30 is formed in the lower part of the tightening body 27 so as to gradually increase in diameter toward the lower end of the tightening body 27.

Therefore, when the tightening body 27 is rotated around the retractable shaft 12 and moved downward, the taper inner surface 30 of the tightening body 27 is moved to each holding piece.
29 is pressed against the threaded portion 11 of the retractable shaft 12, whereby the relative rotation between the tubular portion 9 of the support bracket 3 and the retractable shaft 12 is restricted. The handrail 1 according to the second and third embodiments can be provided on the waist wall 18 as in the case of the first embodiment.

In each of the above embodiments, the handrail member 4
The material is not limited to wood, but other materials such as synthetic resin and metal can be used.

[0017]

As described above, according to the present invention,
Between the handrail member and the support member that supports the handrail member,
Since the height adjusting means for adjusting the supporting height of the handrail member is provided, the height of the handrail member can be easily adjusted without replacing the support bracket, and the handrail according to the height of the occupant can be adjusted. It can be easily obtained.
