Description

[Detailed Description of the Invention] The present invention relates to a fall prevention fence used on a balcony with a handrail.

Although the overhanging balconies of high-rise housing complexes such as condominiums are usually equipped with handrails that rise from the floor, accidents involving children and others still occur.

Taking these circumstances into consideration, the purpose of the present invention is to provide a fall prevention fence that can easily close the opening above the handrail of a balcony, etc. without damaging the existing installation and without any tools, and is extremely easy to attach and detach. It is about providing.

However, according to the present invention, the purpose of the lever is to extend the upper end of the fence frame, which has a recessed part at the lower end for placement and engagement with the upper surface of the upper chord of the handrail, in the backward horizontal direction, and to extend the upper end of the fence frame near the tip of this extended part. A first support body whose position is adjustable is provided at the tip of the extension portion, and one end is attached to the wall at the tip of the extension portion. The gist is that a second support is attached, which is a horizontal rod-shaped body that comes into contact with the upper part of the body and has a length-adjustable means interposed in the middle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 is a front view showing the fence of the present invention installed on a balcony, and Figure 2 is a cross-sectional front view of the same. For example, the handrail 2 has a top rail 2 on the front side of a frame that connects the upper ends of the pillars 2a with upper chord members 2b.
c, a continuous lattice body constituted by the bottom rail 2d and the standers 2e is shown, but it is not necessarily limited to this, and the top rail 2
There are various structures such as those in which c also serves as the upper chord member 2b, and those in which a panel member is attached instead of the lattice body.

3 and 3' indicate fences of the present invention that are placed on the upper surface of the upper chord member 2b of the handrail 2 to close the opening on the handrail 2, and in particular, 3' is easily removed from the outside for emergency access. This is a fence made like this.

First, to explain the general purpose fence 3, Fig. 3 is a front view thereof, Fig. 4 is a vertical side view showing the installed state, Fig. 5 is a side view of the main part, and Fig. 6 is a front view of the same as above. At the lower end of a fence frame 5 in which a wire rod 4 is stretched in an appropriate design shape, a curved claw piece 6, which serves as a recess for placement and engagement on the upper surface of the upper chord member 2b of the handrail 2;
6' is attached downward, and the left and right upper ends of the frame 5 are bent at approximately right angles to form an extension portion 7 extending in the rear horizontal direction. This extension part 7 is provided with a first support body 9 whose end flange 9a abuts against the ceiling surface 8, and the support body 9 is provided with a bolt that is screwed into a reinforcing metal fitting 10 built in the extension part 7 so as to be rotatable therein. By operating the handle 9b at the lower end near the tip of the extension part 7 perpendicular to the vertical direction, the vertical length and horizontal angle can be adjusted.

Further, one end of a horizontal rod-like body 11 as a second support is pivotally attached to the end of the extending portion 7 via a pin 12, and the middle of this horizontal rod-like body 11 is extended as a divided threaded portion. A turnbuckle 13 is interposed as a means for adjusting the height, and a foot rubber 14 is fitted to the other end of the rod-like body 11 so as not to damage the upper part of the wall body 15 to be abutted.

Next, the method of attaching the fence 3 of the present invention described above will be explained with reference to FIG. Grasp the end of the horizontal rod-shaped body 11 and rotate the fence frame 5 using the claw pieces 6, 6' as axes.
Push up until it is vertical.

When the fence frame 5 is vertical as shown in B, turn the handle 9b by hand to adjust the length of the upper part of the first support body 9 that protrudes upward from the extension part 7.
By bringing the tip flange 9a of the first support 9 into contact with the ceiling surface 8, the fence frame 5 is temporarily fixed onto the handrail 2.

Next, as shown in C, the horizontal rod-like body 11 is raised horizontally with the pin 12 as the axis, and the turnbuckle 13 is adjusted to extend the rod-like body 11 so that the leg rubber 14 at the end is pressed and fixed to the upper part of the wall body 15. Do it like this. In this way, the fence frame 5 is attached to the claw pieces 6,
6', a support body 9, and a rod-like body 11 to support and fix from three directions: upper, lower, and lateral. In addition, when removing it, it is sufficient to perform the reverse operation.

Fig. 8 is a side view of the main parts of the embodiment of the emergency access fence 3' shown in Fig. 1, and Fig. 9 is a front view of the same as the above, corresponding to Figs. Components are given the same reference numerals.

In this emergency access fence 3', a sliding sheath tube 17 housing a coil spring 16 inside is provided instead of a turnbuckle in the middle of the horizontal rod-like body 11, and a leg rubber 14 of the rod-like body 11 is provided. is fixed to the outside of the sheath tube 17, while the end on the fence frame 5 side is inserted into the sheath tube 17 and brought into contact with the spring 16, and a wire 18 with one end fixed to the outside of the sheath tube 17 is attached to a rod-shaped body. 11 and the extension portion 7 so that its end portion is exposed on the front side of the fence frame 5,
A handle ring 19 was attached here.

In the figure, 20 indicates a guide ring for the wire 18. The other structure is similar to the above-mentioned general fence 3, but as shown in FIG. 1, it is preferable to provide a mark 21 for emergency access on the front surface.

In this way, when the fence 3' is normally installed, the leg rubber 14 is pressed against the wall 15 by the elastic force of the spring 16 that tends to expand, and the fence frame 5 is
The lock is maintained. On the other hand, in an emergency, if the handle ring 19 is pulled, the sheath tube 17 is also pulled against the spring 16 via the wire 18, the rod-shaped body 11 is shortened as a whole, and the connection between the leg rubber 14 and the wall body 15 is also released. be done.

The rod-shaped body 11 hangs down vertically by its own weight around the pin 12, and the fence frame 5 also automatically falls into the balcony, creating an opening above the handrail 2, so that it is easy to enter the balcony from the outside during fire extinguishing activities. can enter.

Furthermore, as shown in FIG. 2, when the balcony has a difference in width and a corner portion X occurs at the front end, the corner portion can be formed by simply attaching the support 9 to the fence frame 5 as shown in FIGS. 10 and 11. The fence 3'' may be interposed between the fences 3, 3. The fence 3'' is connected to each fence 3 by a hook 22.

As mentioned above, the fall prevention fence of the present invention is intended to block the opening above the handrail of a balcony, etc., but it can be easily set up without damaging existing members or using special tools. ,
It can be quickly and easily attached and detached as necessary.
