Description

  The present invention relates to a fall prevention net for a guard pipe which is attached to the guard pipe to prevent a fall accident or the like of a child.

  Conventionally, as a guard pipe installed near a sidewalk or around a pond, a guard pipe in which a plurality of transverse beams are arranged between columns is used.

JP 2005-171560 A

However, in the guard pipe of the conventional example, the number of the transverse beams is as small as 3, 4 and the gap between the transverse beams is wide, so that an infant or the like goes out to the road side from the gap between the transverse beams, There is a risk of falling to the pond side.
In addition, there is a problem that even if the number of the transverse beams is increased, there is a possibility that the transverse beams may be stepped over the guard pipe.

  The problem to be solved by the present invention is that a guard pipe that can be easily installed on an existing guard pipe and can prevent an infant or the like from falling or getting over the guard pipe without impairing the landscape or view. It is to provide a fall prevention net.

In order to solve the above-mentioned problem, the fall prevention net for guard pipe according to claim 1 is used by being attached to a guard pipe in which a plurality of transverse beams are arranged between columns,
A hook that can be hooked to the transverse beam is provided at the upper edge.

Moreover, the fall prevention net for guard pipes of Claim 2 is a fall prevention net for guard pipes of Claim 1,
The fall prevention net is composed of vertical wires arranged at a predetermined interval and a plurality of horizontal wires connecting the vertical wires.
The hook is configured by bending the upper end of the vertical wire.

Moreover, the fall prevention net for guard pipes of Claim 3 is a fall prevention net for guard pipes of Claim 2.
The vertical wire has a mutual interval of less than 60 mm.

Moreover, the fall prevention net for guard pipes of Claim 4 is the fall prevention net for guard pipes of Claim 2 or 3,
The hook has a chevron shape.

Moreover, the fall prevention net for guard pipes of Claim 5 is a fall prevention net for guard pipes of any one of Claims 1-4,
The vertical wire and the horizontal wire are made of steel wire.

In the fall prevention net for guard pipes according to claim 1, as described above, the hooks that can be hooked on the horizontal beams arranged between the guard pipe columns are provided at the upper end edge portion, so that the existing guard pipes are provided. It will be possible to install the net easily.
In addition, since it is a net, it is possible to prevent an infant or the like from falling outside the guard pipe and getting over the guard pipe without impairing the scenery and the field of view.

  In the fall prevention net for guard pipes according to claim 2, as described above, it is composed of vertical wires arranged at a predetermined interval and a plurality of horizontal wires connecting the vertical wires, and the upper end portion of the vertical wires is bent. The production cost can be kept low because of the simple construction of the hook.

  In the fall prevention net for guard pipes according to claim 3, as described above, even if an infant who can walk by himself wearing shoes is able to walk with his legs on the horizontal beam, the distance between the vertical wires is less than 60 mm. It is possible to prevent it from hanging over the guard pipe.

  In the guard pipe fall prevention net according to the fourth aspect, as described above, the hook can be stably hooked to all the transverse beams having different cross-sectional shapes and thicknesses by forming the hooks in a mountain shape.

  In the fall prevention net for guard pipes according to claim 5, as described above, the vertical wire and the horizontal wire are made of steel wire, so that the strength and durability are excellent.

It is a front view which shows the mounting state of the fall prevention net for guard pipes of Example 1. FIG. It is an enlarged side view which shows the mounting state of the fall prevention net for guard pipes of Example 1. FIG. It is a perspective view which shows a net fixing metal fitting. It is sectional drawing which shows the detail of the fixing | fixed part by a net fixing metal fitting.

  Embodiments of the present invention will be described below with reference to the drawings.

  First, the fall prevention net for guard pipes of the first embodiment will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the guard pipe fall prevention net 2 is used by being attached to the guard pipe 1 in which a plurality of (four in this embodiment 1) transverse beams 12 are arranged between the columns 11 and 11. It is composed of a vertical wire 21 arranged at a predetermined interval and a plurality of horizontal wires 22 connecting the vertical wire 21, and the horizontal beam of the guard pipe 1 is bent at the upper end of the vertical wire 21 into a mountain shape. A hook 23 that can be hooked to the hook 12 is formed.
The lower end portion of the vertical wire 21 is also bent in the same direction as the hook 23.

More specifically, the vertical wire 21 and the horizontal wire 22 are made of steel wire.
Moreover, the mutual space | interval of the said vertical wire 21 is set to less than 60 mm.

Next, the operation of the first embodiment will be described.
Since the fall prevention net for a guard pipe according to the first embodiment is configured as described above, for example, first, a plurality of hooks 23 provided at the upper end of the fall prevention net 2 are provided on the second horizontal beam 12 from the top. By hooking, the fall prevention net 2 can be easily and stably attached to the guard pipe 1.

Then, as the fixing means 3, for example, using the fixing metal fitting shown in FIG. 3, as shown in FIG. 4, the second horizontal beam 12 from the top of the hook 23 and the horizontal beam 12 at the lower end portion are again fixed. Then, the horizontal wire 22 of the fall prevention net 2 is wrapped and fastened with bolts and nuts 31 to complete the mounting and fixing of the fall prevention net 2 to the guard pipe 1.
In addition, as the fixing means 3, any fixing means such as a U bolt or a fastening band can be used.

Next, the effect of the first embodiment will be described.
In the guard pipe fall prevention net of the first embodiment, as described above, hooks 23 that can be hooked on the lateral beams 12 arranged between the support pillars 11 and 11 of the guard pipe 1 are provided at the upper edge. Thus, the net can be easily installed on the existing guard pipe 1.

  Moreover, since it is a net, the effect that the fall of the infant etc. to the exterior of the guard pipe 1 and getting over can be prevented, without impairing a landscape and a visual field.

  Further, the vertical wire 21 is arranged at a predetermined interval and a plurality of horizontal wires 22 connecting the vertical wire 21, and the hook 23 is formed by bending the upper end portion of the vertical wire 21. Therefore, production costs can be kept low.

  In addition, by setting the distance between the vertical wires 21 to be less than 60 mm, it is possible to prevent an infant who can walk on his / her own by wearing his / her shoes from stepping on the horizontal beam 12 and getting over the guard pipe 1. become able to.

  Moreover, by making the hook 23 into a mountain shape, it is possible to stably hook all the transverse beams 12 having different cross-sectional shapes and thicknesses.

  Moreover, it is excellent in intensity | strength and durability by comprising the vertical wire 21 and the horizontal wire 22 with a steel wire.

  Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.

  For example, in the embodiment, the vertical wire 21 and the horizontal wire 22 of the fall prevention net 2 are made of steel wire, but the material is arbitrary, and stainless steel or the like may be used.

  In the embodiment, the hook 23 has a mountain shape, but the shape is arbitrary, and may be a semicircular shape.

  Moreover, although the example which makes the mutual space | interval of the vertical wire 21 less than 60 mm was shown in the Example, the space | interval setting is arbitrary.
