[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail fixing device which can be mounted along a wall surface such as a stairway or a corridor.

[0002]

2. Description of the Related Art A conventional handrail fixing device is, for example, shown in FIG.
As shown in FIGS. 1 to 12, a fixing plate 10 fixed to the base end surface of the main body horizontal portion 1a of the handrail 1 with screws 3 is fixed to a wall surface W such as a stairway or a corridor with screws 3. That is, the fixing plate 10 is formed in a size protruding up, down, left, and right of the base end face of the main body horizontal portion 1a, and is provided on the base end face of the main body horizontal portion 1a through the through holes 7, 7 provided near the center. Hole 8, 8
Screws 3 are fixed to the base end face of the main body horizontal portion 1a.
Screws 3,3,3,7,7 to the wall W of stairs and corridors
It is assumed that 3, 3 are screwed.

[0003]

However, in the above-mentioned conventional handrail fixing device, since the fixing plate 10 is fixed to the handrail 1, the handrail 1 is lifted when it is mounted on a wall W such as a staircase or a corridor. In the state, it must be positioned on the wall W such as stairs and corridors for installation work,
If the handrail is large or heavy, there is a problem that the mounting work is difficult.

In the conventional handrail fixing device, since the screw heads of the screws 3 screwed into the wall surface W of a stairway, a corridor or the like are all exposed directly in front of the fixing plate 10, the fixing device is used by the screw head. Had the problem that the appearance was deteriorated and the appearance became poor. The present invention has been made to solve the problems of the conventional handrail fixing device.

[0005]

Therefore, in the handrail fixing device of the present invention, the protrusions 2 provided above and below the center of the base end surface of the main body horizontal portion 1a of the handrail 1 are fixed to a wall surface W such as a staircase or a corridor. It is designed to be locked to the locking body 4,
The protrusion 2 is a screw head of a screw 3 screwed up and down in the center of the base end surface of the main body horizontal portion 1a.
Are provided with holes 6 with projection locking grooves connected to the insertion holes 5 with projections at upper and lower portions, respectively, and through a through hole 7 provided therebetween, a wall surface W of a staircase, a corridor, or the like. The screw 3 is screwed into this.

[0006]

With the handrail fixing device of the present invention, the locking member 4 can be positioned and fixed in advance at the position where the handrail 1 of the wall surface W such as a staircase or a corridor is to be mounted. Also, in the handrail fixing device of the present invention, the screw head of the screw 3 is hidden inside the fixing device by locking the projection 2 to the locking member 4.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the handrail fixing device of the present invention will be described in detail with reference to the drawings shown as embodiments. FIG.
As shown in FIGS. 5 to 5, in the handrail fixing device of the present invention, the protrusions 2 provided above and below the central portion of the basal end surface of the main body horizontal portion 1a of the handrail 1 are fixed to the wall surface W such as a stairway or a corridor with the screw 3. The locking member 4 is to be locked. That is, the protrusion 2
Are screw heads of screws 3 and 3 screwed up and down in the center of the base end surface of the main body horizontal portion 1a. The locking body 4 is connected to the projection insertion holes 5 and 5 and has a projection locking groove. Holes 6 and 6 are provided to face the upper and lower portions, and screws 3 are screwed into wall surfaces W such as stairs and corridors from through holes 7 provided between the holes 6 and 6. The main body horizontal portion 1a is twisted and the projections 2, 2 are moved into the projection locking holes 6, 6 of the locking body 4 and locked by being inserted into the projection insertion holes 5, 5 of the locking body 4. The screw 3 screwed into the screw hole 8 on the lower surface of the locking member 4 is projected into the protrusion insertion hole 5 to prevent the protrusion 2 from returning to the protrusion insertion hole 5. I have. On the back surface of the locking body 4, a projection 9 is provided which is embedded in the wall surface W of the locking body 4 to prevent the rotation of the locking body 4 when the wall is fixed to the wall surface W of a stair, a corridor or the like with the screw 3.

The handrail 1 is a knob-type handrail, made of an arbitrary material such as wood, synthetic resin, metal or the like, and has a substantially L-shape with a main body rising portion 1b connected to the main body horizontal portion 1a. . The upper part of the main body rising portion 1b is formed into a lump having a size enough to fit in the palm. It is preferable that this mass is formed into an approximately oval shape formed of an ellipsoid or a polyhedron, and when grasped, it becomes familiar to the palm and feels good.

The type of the handrail 1 in which the handrail fixing device of the present invention is used is not particularly limited, such as a normal bar type or a knob type as shown in this embodiment. . As shown in FIGS. 6 and 7, the handrail fixing device of the present invention configured as described above attaches a plurality of knob-type handrails 1 to wall surfaces Wa and Wb such as stairs and corridors at appropriate intervals. As shown in FIGS. 8 and 9,
It can be attached to an appropriate position on the wall surface Wc, Wd of the toilet or bathroom.

[0010]

[Effect of the Invention] The handrail fixing device of the present invention is configured as described above, and the locking body 4 is previously positioned and fixed at the position where the handrail 1 of the wall surface W such as a staircase or a corridor is attached. Since the railing 1 can be lifted, it is not necessary to position the handrail 1 on a wall W such as a staircase or a corridor in a state where the handrail 1 is lifted, and the mounting work is simplified.

Further, in the handrail fixing device of the present invention, the screw head of the screw 3 is hidden inside the fixing device by locking the projection 2 to the locking member 4, so that the screw head is not exposed.
It doesn't look bad.
