Description

The present invention relates to a door mounting structure provided on a fence such as a beast damage prevention fence.

Conventionally, for example, in order to prevent the invasion of various animals such as galvanized iron and deer, a beast damage prevention fence (fence) erected around a field such as a farmland or a farm has been provided at an appropriate place around the field. In addition, columns are erected at regular intervals, and a galvanized iron plate and a grid-like metal net are provided between the columns (Patent Document 1). This prevention fence must be provided with an opening / closing door (gate) for entering and exiting the field.
The conventional door lacks a fence between some of the columns, and a door is installed between them, and the door can be opened and closed by tying the frame of the door to the columns with a string or a metal wire.

Japanese Patent Application Laid-Open No. 2003-92976

Tying with the above strings is weak and deteriorates over time, so it is often necessary to repair it.
In addition, the door can be freely opened and closed on the column with a metal hinge, but the installation of the hinge on the column and frame involves welding and drilling, which is troublesome and costly. It has become a thing.
Further, although a door opening / closing structure using a double cylinder has been devised, it is complicated to attach the cylinder to a support column (see Patent Document 1, FIGS. 5 to 8 and the like).

It is an object of the present invention to obtain an inexpensive and durable door structure under the above circumstances.

In order to achieve the above object, the present invention is a door mounting structure in which a door is provided in a part of the fence, and a support ring fitted to a vertical column of the fence and a door in the vertical direction. It consists of another support ring fitted in the mounting rod and a connecting plate that connects the two support rings, and both of the support rings are divided by a part of the periphery so that the diameter can be expanded. Each connecting piece protrudes forward from the split edge, and the connecting pieces are overlapped and fastened with bolts and nuts to form the connecting plate, and one of the two support rings is fixed to a support or a mounting rod. The other is configured to be rotatable on the mounting door or support.

By doing so, both support rings can be expanded in diameter and fitted to the pillars of the fence and the mounting rod of the door. A door is attached to the support column by forming a connecting plate and integrating both support rings. In the mounted state, since at least one of the support rings is rotatably fitted to the strut or the mounting rod, the door is rotatable with respect to the strut or the mounting rod. Therefore, the door can be easily opened and closed.

In the above configuration, if at least one of the two support rings is composed of a pair of half-split members and the opposite edges of the partial split portions are connected by a hinge, the support ring having the hinge is a hinge. Since it is easy to expand the diameter through the support, it is easy to fit it by the support or the mounting rod.

Since the present invention is configured as described above, it is possible to provide an inexpensive and highly durable door mounting structure.

An embodiment of a beast damage prevention fence according to the present invention is shown in FIGS. 1 to 6, and in this embodiment, the prevention fence 10 is provided around a farmland where beasts such as wild boar A are infested.
In the prevention fence 10, columns 11 are built on the ground G at regular intervals, square fences 12 are provided between the columns 11 and 11, and some of the columns 11a and 11a are used as entrances and exits to agricultural land. A door 20 is provided in the door 20. Each column 11 (11a, 11a) is formed into a pile shape and is driven into the ground G so as not to fall.

The fence 12 is configured by arranging vertical lines 12b and horizontal lines 12c made of metal wires in a grid pattern on a square frame (frame) 12a and welding the contact points thereof.
Even if the support columns 11 are not provided for each fence 12, the support columns 11 between the fences 12 and 12 can be appropriately omitted as long as the fence 12 can be integrated by binding with a wire or the like. That is, every few fences 12 may be used. The vertical line 12b of the fence 12 can be long enough to reach the ground G. In particular, when the support column 11 between the fences 12 and 12 is omitted, the fence 12 is stabilized on the ground G by allowing the vertical line 12b to reach the ground G.

The door 20 is a double door and is composed of a pair of doors 20a and 20b. The column 11a on which the door 20 is located is thicker and stronger than the other columns 11.
Similar to the fence 12, the door 20 (20a, 20b) is configured by arranging vertical wires 21b and horizontal wires 21c made of metal wires in a grid pattern on a mounting rod 21 of a square frame and welding the contacts thereof. Has been done.
The structure in which the door 20 is attached to the support column 11a is a feature of the present invention, and the door 20 can be opened and closed by the support column 11a of the fence 12 via the opening / closing mechanism 30.

As shown in FIGS. 2 to 6, the opening / closing mechanism 30 includes one support ring 31 on the support side to be attached to the support 11a of the fence 12 and another support on the door side to be attached to the mounting rod 21 of the frame frame of the door 20. It consists of a ring 32.
Both support rings 31 and 32 can be expanded in diameter by dividing a part of a cylindrical shape in the vertical direction (cylindrical axial direction), and are reinforced by providing ribs 33 all around the center in the width direction. A connecting piece 34 is integrally projected on the split edges of both the support rings 31 and 32, respectively. Each of the four connecting pieces 34 is overlapped and passed through the bolt 35 and fastened with the nut 36 to form a connecting plate.
One support ring 31 on the support column 11a side is also split on the opposite side of the split edge and connected by a hinge 37 so that the connecting piece 34 can be opened and closed.
Both support rings 31, 32 and a connecting plate (connecting piece 34) are made of a metal plate that has been subjected to rust prevention treatment.

The door mounting structure of this embodiment is as described above, and as shown by the chain line in FIG. 6, the connecting piece 34 of both support rings 31 and 32 is opened, and each support ring 31 is attached to the support ring 11a and the mounting rod 21 of the door 20. , 32 are fitted, and then, as shown in FIGS. 2 to 5, the connecting pieces 34 of both support rings 31 and 32 are overlapped and fastened with bolts 35 and nuts 36. By this fastening, one of the two support rings 31 and 32 is fixed to the support column 11a or the mounting rod 21, and the other is rotatable to the mounting rod 21 or the support column 11a.

In one embodiment of this embodiment, as shown in FIG. 3, the support ring 31 is fixed to the support column 11a, and the support ring 32 on the door 20 side is rotatable to the mounting rod 21. Therefore, the door 20 attached to the support column 11a by the opening / closing mechanism 30 moves from the solid line in FIG. 3 to the mounting rod 21 via the opening / closing mechanism 30 as shown by the chain line or vice versa. Easy to get in and out of.
On the other hand, in another embodiment shown in FIG. 4, as shown in the figure, the support ring 32 is fixed to the mounting rod 21, and the support ring 31 on the support column 11a side is rotatable to the support column 11a. Therefore, the door 20 attached to the support column 11a by the opening / closing mechanism 30 moves from the solid line in the figure to the support column 11a via the opening / closing mechanism 30 as shown by the chain line or vice versa, and thus goes to the agricultural land. It is easy to get in and out.

As shown in FIG. 1, the mounting positions (vertical direction) of the support rings 31 and 32 on the columns 11a and the mounting rod 21 are appropriately set up and down so that the door 20 can be smoothly opened and closed. At this time, since the support rings 31 and 32 on the fixed side are fixed to the support column 11a or the mounting rod 21 so as not to be vertically movable by fastening the bolts and nuts 35 and 36, the opening / closing mechanism 30 does not move in the vertical direction but is fixed. The side support ring 31 or 32 may be placed on the ends of the horizontal lines 12c and 21c of the fence 12 or the door 20 (see the horizontal line 12c in FIG. 2), or a downward stopper piece may be welded to the support column 11a or the mounting rod 21. It is preferable to fix it. On the other hand, it is preferable that the support rings 31 and 32 on the rotating side abut on the lower side of the horizontal lines 21c and 12c of the door 20 or the fence 12 (see the horizontal lines 21c in FIG. 2).

In this embodiment, the diameter of the support ring 31 on the support column 11a side can be expanded by the hinge 37, but the diameter of the support ring 32 on the mounting rod 21 side can also be expanded by the hinge. That is, at least one of both support rings 31 and 32 can be freely expanded by a hinge. However, even if it is not a hinge, if there is a split edge, the diameters of the support rings 31 and 32 can be expanded (see FIG. 6), so that the hinge 37 does not necessarily have to be provided.
In this embodiment, there is no work such as welding or mounting a split pin, and the door 20 opening / closing mechanism 30 is configured by fitting both support rings 31 and 32 and tightening bolts and nuts, so that the door 20 can be installed easily. Is good.

The door 20 of this embodiment has a double door, but of course it may be a single door.
Further, it is needless to say that the fence 12 is not limited to the grid-like shape of the square frame composed of the vertical and horizontal metal wires 12b and 12c, and a well-known embodiment such as a galvanized iron plate can be appropriately adopted.
Although the embodiment relates to a beast damage prevention fence, the present invention is to provide a gate for a fence other than the beast damage prevention fence, for example, a fence for livestock, a fence around a photovoltaic power generation facility, and the like. Can be adopted for.
Thus, the embodiments disclosed this time should be considered to be exemplary and not restrictive in all respects. The scope of the present invention is indicated by the scope of claims and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
