Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing each end of a handrail between two opposing walls in close contact with the wall surface.

The present inventor previously issued patent No. 898648 (Japanese Patent Publication No. 52-2
4769) proposed a method of constructing the end of the handrail on the wall surface.

This method involves incorporating an auxiliary material into each of the handrail rail and the bar to which it is attached, pulling out the auxiliary material of the bar the required length from the end of the bar, fixing the tip to the wall, and then attaching the auxiliary material of the handrail rail to the tip. The handrail is pulled out until it collides with the wall surface, and is then fixed to the bar or an auxiliary member of the bar, and can only be applied to handrails where the handrail cross member consists of two members: a rail and a bar.

Therefore, the present invention improves the above-mentioned prior art so that even if the handrail cross member is made of a single member, such as a handrail rail, it can be constructed in the same way by pulling out the auxiliary member.

The present invention will be explained below with reference to the illustrated embodiments.

In Figures 1 to 3, 1 is a hollow handrail cross member whose lower surface is also closed by a bottom wall 1, and inside thereof there are retaining strips 2, 2 facing left and right, and both retaining strips 2, 2 are attached to the tip. A wall surface fixing material 3, which is fixed to a wall surface, is slidably held.

Moreover, the handrail cross member slidably holds an auxiliary cross member 4 inside thereof, in addition to the wall surface fixed cross member 3.

In this embodiment, the retaining strips 2, 2 extend from the left and right sides of the bottom wall 1 at a slight distance from the side walls 1a, 1a in an inverted L-shape, and the lower surfaces of the tip portions 2/, 2/ that are curved in opposite directions form the wall fixing member 3. and bottom wall 1'J:. The auxiliary cross member 4 is held between the left and right side walls 4/
, 4/ are inserted between the side walls 1a, 1a of the handrail cross member and the back surfaces of the retaining strips 2, 2.

However, the retaining strips may also protrude from the lower portions of the side walls 1a, 1a of the cross members in opposite directions.

The wall fixing material 3 has an L-shaped raised wall contact portion 3' at its tip, a hole is provided in this S, and screws, concrete nails, etc. are passed through the wall contact portion 3' to fix it to the wall surface.

This handrail horizontal member 1 can be used as both the upper horizontal member a and the lower horizontal member b of the handrail.

That is, when used as the upper horizontal member a, the member d attached to the upper end of the baluster C may be appropriately fixed to the lower surface of the bottom wall 1, for example, with screws, and when used as the lower horizontal member b, the member This is because the lower end of the handrail can be fixed by passing a long screw through the lower surface and protruding from the upper surface.

Of course, this operation may be performed after the cross member 1 is fixed to the wall surface by the wall surface fixing member 3, or may be performed before the cross member 1 is fixed to the wall surface.

Whether used as the upper or lower cross member, cut the handrail cross member 1 to an appropriate length that is slightly shorter than the wall spacing, and attach the wall fixing material 3 and the auxiliary cross member at the end. Insert the material 4,
The wall surface fixing member 3 and the auxiliary cross member 4 are each pulled out, their tips are brought into contact with the wall surface to be fixed, and each is fixed in that state.

The wall fixing material 3 is fixed to the wall through the hole in the abutment part 3' as described above, and the handrail cross member is fixed to the bottom wall 1.
All you have to do is pass the screw 5 from the bottom of the holder and tighten it.

Further, the auxiliary cross member 4 may be fixed by hooking its tip to a wall fixing member as disclosed in the prior art, or by tightening it through screws 6 so as not to be noticeable from the side wall of the cross member or the soil wall. good.

In addition, when using the handrail horizontal member 1 as the upper horizontal member, the bottom wall 1'
If a groove 7 into which the member d is fitted is formed on the lower surface of the member and the member d is fitted into the groove, the member d is not visible and has a good appearance.

Further, the length of the wall fixing member 3 and the auxiliary cross member 4 protruding into the cross member 1 is set to such an extent that it does not interfere with the fixing of the handrail C and the member d attached to its upper end.

The embodiment shown in FIGS. 4 and 5 is a modification of FIGS. 1-3.

The handrail cross member 21 is hollow, and the bottom wall 21 has a groove 22 that is deeply recessed inward and opens downward, and the opening of the groove 22 has protrusions 22', 22' that protrude oppositely. It is provided.

Therefore, the wall fixing member 23 having an abutting portion at one end can be slidably held in the groove 22 by the protrusions 22'22' without falling off.

An auxiliary cross member 24 is slidably held in the hollow interior of the handrail cross member 21.

In the embodiment shown in Figures 1 to 3 described above, both the wall fixing material and the auxiliary cross member were slidably held inside the hollow part of the handrail cross member, but in this embodiment, only the wall fixing material was held inside the hollow part. It is meant to be slidably held on the outside of the body.

Therefore, this embodiment can also be applied to a wall surface in the same way as those in FIGS. 1 to 3.

When used as an upper horizontal member of a handrail, the piece d to which the upper end of the handrail C is attached can be supported in the groove 22 in the same way as a wall fixing member.

As is clear from the above, according to the present invention, the single handrail cross member constituting the upper or lower cross member of the handrail holds the husband wall fixing member and the auxiliary cross member, and the wall fixing member is pulled out. In addition to fixing the tip to the wall, the wall fixing material is covered with an auxiliary horizontal material that pulls out, making it possible to easily construct the handrail on site without having to cut the handrail horizontal material exactly to the length between the walls. It has characteristics.

Additional Relationships This invention allows the handrail cross member to hold the wall fixing material and the auxiliary cross member at the end thereof in a removable manner, pull out the drawing material from the end of the handrail cross member and place the tip against the wall surface, and the wall fixing material holds the wall surface fixing material on the wall surface. This invention incorporates the essential features of the structure of Patent No. 898648 (Japanese Patent Publication No. 52-24769) in that the auxiliary cross member is fixed to the wall fixing member or the handrail cross member. This shall be the main part of the structure.
