[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for supporting a handrail, and can be used, for example, for a handrail installed on a handrail installation having an inclined angle such as a staircase.

[0002]

2. Description of the Related Art For example, a handrail installed on a balcony of a house is horizontally supported by the tip of a vertically erected column, but is installed on an installation having an inclined angle such as a staircase. Is tilted and supported at an end corresponding to the inclination angle at the tip of a column vertically erected from the installation, and the column at this time is fixed to the installation at an angle.

FIGS. 6 to 8 show a conventional example in which a handrail 52 is installed on a handrail installation object 51 having an inclination angle like a staircase. In the conventional example of FIG. 6, a counterbore 53 is provided in the installation object 51, a base end portion of a column 54 is inserted into the counterbore 53, a ceramic ball 55 or the like is embedded, and then fixed by filling with a filler. I do. In the conventional example of FIG.
A reinforcing member 57 is vertically erected on the installation object 51 via a base member 56, a hollow column 58 is fitted to the outside thereof, and a cover 59 is put on the lower portion of the reinforcing member 57 and the column 58, The lower ends of the reinforcing members 57 and the columns 58 are cut at an angle that matches the inclination angle of the installation object 51. In the prior art shown in FIG. 8, a lower portion of a bolt shaft 60 formed by cutting a long bolt rod is screwed into an anchor member 61 in an installation object 51, and a base member 6 is attached to a lower portion outside the same.

An operation of cutting the lower ends of the columns 58 and 63 obliquely or an operation of cutting a long bolt rod to obtain a bolt shaft 60 having a length corresponding to the column 63 must be performed. Therefore, it takes a lot of trouble and time, and in particular, the work of cutting the lower ends of the reinforcing members 57 and the columns 58 and 63 obliquely must be performed at an accurate angle that matches the inclination angle of the handrail installation object 51. The cutting angle must be changed for handrail installations having different inclination angles, and there is a problem that there is no versatility for various handrail installations having different inclination angles.

It is an object of the present invention to provide a handrail support structure which can simplify the work and has versatility for various handrail installation objects.

[0006]

In a handrail support structure according to the present invention, a support for supporting a handrail at a tip end portion is fixed to a handrail installation object via a base article, and the basic article comprises: A first foundation member attached to the handrail installation;
A second base member to which a base end of the column is coupled, the second base member being rotatable with respect to the first base member and being freely rotatable with the first base member at an arbitrary rotation position. We have been,
A second base member attached to the handrail installation
Fastening in which the base members fasten only these base members
It is characterized by being fastened with a tool .

According to the present invention, the support of the handrail is fixed to the handrail installation through the basic article, and the basic article is the first
A second base member having a base member and a second base member, wherein the first base member is attached to the handrail installation, and a second end to which a base end of the support is coupled.
The base member is rotatable with respect to the first base member and the first base member.
Attachment of the first base member to the handrail installation is possible because it can be fastened to the base member at any rotational position.
After the second base member is rotated with respect to the first base member, an operation of fastening the first base member and the second base member and an operation of connecting the base end portion of the support to the second base member are performed. Thereby, the operation of fixing the support to the handrail installation object at a predetermined angle can be completed, and this operation can be completed easily and in a shorter time than before, and the rotation angle of the second base member with respect to the first base member. By appropriately setting the fixed angle of the support with respect to the handrail installation, it is possible to arbitrarily determine the fixing angle of the support to the handrail installation. Will have.

As described above, the present invention can be applied to a handrail installed on a handrail installed inside a building or a handrail installed on a handrail installed outside a building. An example of the handrail installed is: The present invention can also be applied to a handrail installed on a pedestrian crossing of a road, which is a stair or a slope for a physically handicapped person.

Further, the present invention is not limited to a handrail supported by a vertical support, but a handrail supported by a horizontal support, in other words, supported by a support protruding horizontally from a wall surface of a building. It can be applied to handrails for elderly people and the physically handicapped, as well as handrails supported by pillars that are inclined with respect to the horizontal direction, where the pillars and the handrail installation make an angle. Applicable to

[0010] Further, usually, only a part of the columns supporting the handrail by a plurality of columns makes an angle of 90 degrees with the handrail installation object, and the other columns form an angle other than 90 degrees. In addition, the present invention can be applied to this case, and an example of this case is a case where a handrail is continuously installed on a staircase provided with a horizontal landing in the middle.

The present invention is also directed to a case in which a part of a plurality of pillars supporting a handrail and another pillar have different angles formed with a handrail installation object, or a plurality of pillars. Can be applied to the case where the angle between the handrail and the handrail installation gradually changes from one end of the handrail to the other end, and furthermore, the handrail installation in which a support is fixed via the basic article. The present invention can be applied not only to the case where the surface of the object is flat, but also to the case where the surface is curved or curved.

The rotation of the second base member with respect to the first base member may be two-dimensional or three-dimensional.
What is necessary is just to determine according to dimensional or three-dimensional.

Further, in order to make the second base member rotatable with respect to the first base member, these base members are connected via a pin serving as a center of rotation, and the number of pins is reduced to one. When the second base member is two-dimensionally rotatable and the pins are two orthogonal to each other, the second base member can be three-dimensionally rotatable, respectively. By providing a curved convex portion on one of the base members and a curved concave portion in surface contact with the curved convex portion on the other, the second basic member can be made rotatable relative to the first basic member. If the curved convex portion and the curved concave portion are two-dimensional, this rotation is two-dimensional, and if three-dimensional, this rotation is three-dimensional.

By providing a curved convex portion on one of the first and second basic members and a curved concave portion on the other, the second basic member is rotatable with respect to the first basic member. In this case, the contact area between the first base member and the second base member can be increased, so that greater strength against external force can be ensured than in the case where a connection structure using pins is employed.

[0015] When the installation surface of the handrail installation object to which the first base member is attached is inclined with respect to the horizontal direction and the support is vertical, a curved projection is formed on one of the first base member and the second base member. When each of the portions has a curved concave portion on the other side, it is preferable to provide an upwardly convex curved convex portion on the first base member and provide a curved concave portion on the second base member.

With this configuration, unlike the case where the curved concave portion that is depressed downward is provided in the first base member, it is possible to prevent the accumulation of dust and the like in the curved concave portion of the first base member, and it is possible to prevent the handrail from being installed. When is installed outside the building, rainwater can be prevented from accumulating in the curved concave portions other than the dust, so that good appearance can be maintained.

By providing a two-dimensional curved convex portion on one of the first base member and the second basic member, and a two-dimensional curved concave portion in surface contact with the curved convex portion on the other, respectively.
In a case where the base member is rotatable two-dimensionally with respect to the first base member, in order to be able to fasten the second base member to the first base member at an arbitrary rotation angle, these base members are required. May be used, but holes may be formed in the curved convex portions and concave portions of these base members, and the second base member may be fastened by a fastener such as a bolt or nut inserted into these holes. When the members are fastened to the first base member, the fastening structure of these base members can be simplified.

In the case where the second base member is fastened to the first base member by such a fastener, a hole formed in one of the first base member and the second base member is formed in the second base member. The long hole may be long in the rotation direction of the member, and the other hole may be a simple round hole. However, it is preferable that both holes are long holes in the rotation direction of the second base member.

If both holes are elongated in the direction of rotation of the second base member, the turning distance of the second base member with respect to the first base member can be increased. As a result,
The effect that the rotation angle of the second base member can be increased can be obtained.
