DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail installed on a wall surface of a stairway, a corridor or the like, wherein a support is attached to an arbitrary position of a handrail member.

[0002]

2. Description of the Related Art Conventionally, as a handrail having a support attached to an arbitrary position on a wall surface and a handrail member attached to the support, Japanese Utility Model Publication No. 54-7853 discloses a handrail having an opening in the longitudinal direction. A cylindrical handrail member formed and arranged in parallel with a clamping edge folded inward at a substantially right angle along an opening edge, and a support member for attaching the handrail material to a wall surface or the like at appropriate intervals. The support has a mounting provided with a pedestal at one end and a head at the other end, and a recess at the head, and a horizontal member wider than the opening of the handrail member. At the center of the plate-shaped receiving portion, a locking projection having a width slightly smaller than the width of the opening was formed substantially perpendicular to the receiving portion to form a convex shape, and a leg portion was formed on the back surface thereof. It consists of a receiving device and a fixing device having a U-shaped cross section, and a pedestal of the mounting device is screwed to a wall surface, and a leg portion of the receiving device is provided in a recess of the mounting device. The handrail is engaged with the head, and the opening of the handrail is fitted to the locking projection of the receiving member, and the projection is sandwiched by the clamping edge of the handrail. A stair handrail has been proposed in which is supported by a receiving portion of a receiving device, a locking projection of the receiving device and a holding edge of a handrail material are held by a fixing device, and the receiving device and the fixing device are screwed. ing.

[0003]

However, in such a handrail as described above, rattling is likely to occur in the horizontal direction because the clamping edge of the handrail material is merely clamped by the locking projection of the receiving tool and the fixing tool. There was a problem. Also, since an opening is provided over the entire length in the longitudinal direction at the lower part of the handrail material,
When gripping the handrail, the fingertip touches the opening and there is a problem that it is difficult to grip.

Accordingly, the present inventor has conducted intensive studies in view of the conventional drawbacks, and as a result, has provided a handrail in which a handrail member can be securely attached, is easy to construct, and is easy to grasp.

[0005]

According to a first aspect of the present invention, there is provided a handrail having an opening formed in a longitudinal direction, and holding walls which are inclined so as to become wider inward in the opening. A cylindrical surface comprising a contact surface formed on the sandwiching wall, and a hollow portion extending inward from a second opening formed between edges of the opposed contact surfaces. A handrail member, a support for attaching the handrail member to a wall surface or the like at appropriate intervals, and a sliding penetrating body having female threads formed at both ends, and the support is provided with a pedestal at an end. The other end is provided with a sliding mounting portion, and a screw hole corresponding to a female screw position formed in a sliding penetrating body at both ends of the sliding mounting portion is formed, and the sliding penetrating member is provided with the handrail member.

An opening 13 is formed on the lower surface of the core material 11, and a synthetic resin layer 12 formed on the surface of the core material 11 is formed on the outer surface of the core material 11 and inside the opening 13. The resin layer 12 is inclined so as to become wider inward and forms a sandwiching wall 14. A step 15 is formed at the edge of the sandwiching wall 14, and the second
The space is expanded in a circular cross section from the second opening toward the center of the handrail member 1, and the hollow portion 1 is formed.
6 has been set.

Reference numeral 2 denotes a support. A flange is formed at one end of the arm 21, and a screw hole is provided at an edge of the flange to form a pedestal 22. A sliding attachment portion 23 is formed at the other end of the arm 21 of the support 2, and screw holes are formed at both ends of the sliding attachment portion 23. The side wall of the sliding attachment portion 23 has a shape adapted to the inner shape of the core 11 constituting the handrail member 1.

The position of the stud on the wall of the place where the handrail is to be attached, such as a staircase or a corridor, is confirmed, and the pedestals 22 of the support 2 are attached to this position at appropriate intervals. And the sliding penetrating member 2 screwed to the sliding mounting portion 23
The edge of the opening 13 of the handrail member 1 is inserted into the gap with
This edge is sandwiched between the slide attachment portion 23 and the slide penetrator 24, and the handrail member 1 is attached to the support 2. Opening 1 other than the part attached to support 2 of opening 13 of handrail member 1
A cover 3 is inserted into 3. The locking portion of the cover 3 is locked to the edge of the opening 13 of the handrail member 1, and convex portions 31 are formed on the surface thereof at appropriate intervals to form a holding portion. The distance between the convex portions 31 formed on the holding portion on the surface of the cover 3 is 18
３０30 mm is a preferred dimension. The cover 3 is formed by appropriately molding a material such as a synthetic resin or a synthetic rubber.

FIG. 5 shows another embodiment of the support. The support 2 is provided with a pedestal 22 provided with a screw hole at the edge of a flange at one end of an arm 21 and a slide at the other end. A dynamic mounting portion 23 is provided, a squeezing portion is formed in the sliding mounting portion 23, and a sliding penetrating portion 24 'is formed at the other end of the slicing portion. A V-shaped groove is formed at the top of the sliding penetration portion 24 '. The wedge 25 has a trapezoidal cross section, and a female screw portion is provided on a long side thereof. Wedge 25 having a V-shaped outer wall adapted to the inclined inner walls on both sides of this V-shaped groove
Are inserted into the grooves, the inclined outer walls of the wedges 25 abut against the respective inclined inner walls of the grooves, and the fastening screws are threaded through the sliding penetration portions 24 ′ into the female screw portions provided on the wedges 25. When inserted, the inner wall of the sliding penetration portion 24 ′ is pressed against the outer wall of the wedge 25,

The support 2 is attached to a wall surface such as a staircase or a corridor. If the wall surface is uniform and strong, such as a concrete structure, it can be attached to an arbitrary position. In this case, it is necessary to confirm the position of the base studs and the like, and to attach the reinforcing member to the position. In the case of stair handrails, even if the studs are equally spaced, if the slope of the stairs changes, the spacing between the bracket positions on the handrail side must be changed. Because of this,
A handrail capable of attaching the support 2 to an arbitrary position of the handrail member 1 has been demanded.
