Description

[Detailed Description of the Invention] This invention relates to a tool for mounting a guardrail that is installed close to a wall surface of a hallway or an elevator, for example.

Conventionally, when installing this type of guardrail, the guardrail was attached by sliding it from the side with respect to a support fixed to a wall surface.

Therefore, if the wall surface is uneven, it is difficult to install the device near a pillar in a hallway or in a narrow place, such as in an elevator.

Furthermore, since the distance between the guardrail and the wall surface is narrow, there is an inconvenience that installation work is troublesome.

This idea was developed in view of the above circumstances, and the feature is that the installation that can be attached to the back side of the guardrail can be easily installed by simply sliding the piece that is attached to the back side of the guardrail, without having to slide the guardrail laterally. The purpose of the guardrail installation is to provide the following tools:

Examples of this invention will be described below based on the drawings.

Figures 1 to 4 show the first embodiment of the mounting device of this invention. In the figures, 1 is a guardrail, and the back side, that is, the mounting surface, has a C-shaped cross section approximately in the center. A shaped engagement groove 1a is provided longitudinally through the engagement groove 1a.
A is fitted so that the piece 2 can only be slid.

As shown in FIG. 3, this mounting piece 2 includes a slide piece 2a that fits into the engagement groove 1a of the guardrail 1, and a retaining part 2b that protrudes from one side of the slide piece 2a.
and the guardrail 1 is attached to the engaging portion 2b.
, that is, along the slide piece 2a.
Set up and open.

In this case, the engaging recess 2C has a substantially C-shaped cross section and is open only at the - side end, but the cross section does not necessarily have to be C-shaped, and in the longitudinal direction. It is sufficient that the orthogonal openings are slightly narrower so that the later-described retaining head 6b that fits into the engagement recess 2C does not come out, and that at least one side end of the engagement recess 2C is open. All you have to do is do it.

Reference numeral 3 denotes a wall surface to which the guardrail 1 is mounted, and a support 4 protruding from the wall surface 3 is fixed to the wall surface 3 with a fixing device (not shown) such as an anchor bolt.

In this case, as shown in FIG. 4, the support 4 includes a fixed leg 5 having a flange portion 5b at one end of a threaded cylindrical portion 5a for fixing to the wall surface 3, and a threaded cylindrical portion of the fixed leg 5. Part 5
A male threaded portion 6 that is threadedly coupled to the female threaded portion 5C provided in a.
an adjuster 6, which has an engaging head 6b at its tip that can be slidably fitted into the engaging recess 2C of the mounting piece 2; and a threaded tube of the fixed leg 5. It is comprised of a tightening cover 7 which is screw-coupled with a male screw portion 5d provided on the portion 5a and can move forward and backward on the tip of the screw cylinder portion 5a, and as shown in FIG. After fixing to the wall surface 3, the adjuster 6 and the tightening cover 7 are attached to the female threaded portion 5C and the male threaded portion 5d of the threaded cylinder portion 5a of the fixed leg 5, respectively, and the tightening cover 7 is moved toward the wall surface.
Rotate the adjuster 6 to adjust the level to a desired protruding state.

At this time, it is necessary to keep the longitudinal direction of the joint head 6b in a horizontal state.

In this state, the guardrail 1 to be attached is brought closer to the wall surface 3, and the mounting piece 2, which has been fitted in advance into the engagement groove 1a of the guardrail 1, is moved closer to the engagement groove 1a.
1, and after engaging the engaging recess 2C of the piece 2 and the retaining head 6b of the adjuster 6, move the tightening cover 7 toward the guardrail side, as shown in FIG. Thus, the guardrail 1 is attached by tightening its tip to the guardrail 1 to ensure engagement between the engagement recess 2C and the engagement head 6b.

5 and 6 show a second embodiment of this invention, in which the engaging recess 2C and the engaging head 6b in the first embodiment are shown.
This is the case when the two are expressed in reverse.

That is, the attachment is performed by forming the retaining head 2d at the tip of the engaging portion 2b of the piece 2, and by fitting the engaging head 2d to the tip of the adjuster 6 of the support 4 so that it can only slide. This is a case where a mating recess 6C is provided.

Note that other parts are the same as those of the first embodiment, so the same reference numerals are given and the explanation thereof will be omitted.

7 and 8 show a third embodiment of this invention, in which the engagement head 6b of the support 4 is always mounted in a horizontal state where it can engage with the engagement recess 2C of the piece 2. This is the case when considering that it can be maintained at

That is, as shown in FIG. 7, a fixed leg 5' is provided with a flange portion 5b' at one end of the rectangular projection 5a', and a male threaded portion is provided on the side surface of the distal end of a box-shaped body 6d' that is fitted into the rectangular projection 5a'. 6a' is provided protrudingly, and an engagement head 6b extending in the horizontal direction is provided at the tip of the male threaded portion 6a'.
and a tightening cover 7' (see FIG. 8) which is threadedly coupled to the male threaded portion 6a' of the adjuster 6', and a support 4 is constructed. 6d'
The level of the adjuster 6' can be adjusted using a fixing screw 8 which is threadedly connected to the hole 5c'. This is how it was done.

If formed in this manner, there is no need to position the engaging head 6b, that is, to set it in the horizontal direction during the installation shown in FIG. 8, and the installation can be carried out quickly.

9 and 10 show a fourth embodiment of this invention, in which the mounting piece 2 is formed in a different form.

In other words, for installation, attach the piece 2 to the retaining groove 1 of the guardrail 1.
It is composed of a slide piece 2a that is slidably fitted into the slide piece 2a, and a retaining part 2b that protrudes from one surface of the slide piece 2a. This is a case where an engaging recess 2c' extending in the direction is formed, and an opening is provided at least at the lower end of the engaging recess 2C'.

With this configuration, the manner of attachment is different from that of the previous embodiment, and as shown in FIG.
When the retaining head 6b provided on the adjuster 6 of the support 4 attached to the support 4 is positioned vertically, the mounting piece 2 is lowered together with the guardrail 1, and the engaging recess 2
After C' is engaged with the retaining head 6b, the tightening cover 7 is tightened and the guardrail 1 is attached.

In addition, in each of the above embodiments, the installation is explained in the case where the piece 2 is slidably fitted into the engagement groove 1a provided in the guardrail 1, but the structure is not limited to this. For example, as shown in FIG. 11, a retaining member 1a' having a T-shaped cross section and a retaining piece at the tip is provided approximately at the center of the back surface of the guardrail 1 along its longitudinal direction, and the attachment is done by attaching it to the piece 2. It is also conceivable that an engagement groove 2e that is slidably fitted into the engagement member 1a' is provided on the opposite side surface, and that the piece 2 is slidably attached to the back surface of the guardrail 1. .

Further, it is not necessary to provide the adjuster 6 or 6' in the support 4, and the same effect can be obtained even if the support is a fixed type.

As explained above, according to the tool, the device is attached to the engagement head or engagement recess provided at the tip of the support protruding from the wall, along the back surface of the guardrail that is attached to the wall. In the case of sliding installation, the guardrail can be attached by engaging the engagement recess or the engagement head of the piece and then tightening the tightening cover attached to the tip of the support. is extremely easy to work with, and since the guardrail itself does not need to be slid laterally, it is easy to install on uneven walls or in narrow spaces, and can be installed in a wide range of locations. , its utility value is remarkable.
