Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fence that can be easily constructed in a bent state according to the conditions of the installation location.
[0002]
[Prior art]
Conventionally, when a fence is bent in accordance with the shape of the boundary portion of a site, a plurality of vertical lattices are provided with a predetermined interval between upper and lower horizontal rails as described in JP-A-7-197701. The fence body is used, the pillars equipped with angle adjustment brackets, etc. are erected at predetermined intervals along the boundary part, and both ends of the fence body are attached to the pillars via the angle adjustment brackets etc. Yes.
[0003]
[Problems to be solved by the invention]
In the conventional structure, even if the angle between the fence bodies adjacent to each other can be changed, the fence bodies themselves are straight, so when looking at the entire fence, it does not necessarily match the shape of the site. It is difficult to say.
[0004]
In addition, since the fence body that is adjacent to the support post is attached in a bent shape, it is necessary to install a support post at each bending position when installing a fence along the shape of the boundary where the boundary part is intricately intertwined. In addition, the number of support columns increases more than necessary, and it is necessary to attach fence bodies having different lengths between the support columns according to the interval between them, resulting in poor appearance.

DETAILED DESCRIPTION OF THE INVENTION
Below, each embodiment of the fence concerning the present invention is explained in full detail based on a drawing. 1 to 4 exemplify a first embodiment of the present invention, FIG. 1 is a plan view of a fence installed in a bent shape along the shape of the site, FIG. 2 is a front view thereof, FIG. FIGS. 4A and 4B show details of each part.
[0008]
1 and 2, reference numeral 1 denotes a support, which is erected on the ground side at a predetermined interval along the boundary of the site 2. Reference numeral 3 denotes a fence body, and a plurality of, for example, three upper, middle, and lower horizontal beam members 4 arranged in parallel in the horizontal direction, and a predetermined interval along each horizontal beam member 4 are arranged. A plurality of (a plurality of) vertical lattices 5 arranged in the vertical direction across the crosspiece member 4 and having a predetermined shape such as an arc shape, a straight line shape, or an S shape along the boundary shape of the site 2 It is configured. Each fence body 3 is disposed between the columns 1 and both ends of the horizontal beam members 4 are fixed to the fixtures 6 on the column 1 side.
[0009]
A hollow cylindrical hollow body is used for the support column 1 and the vertical lattice 5. In addition to the cylindrical body such as an ellipse, a quadrangle, and a polygon, the solid bodies such as a circle, an ellipse, a quadrangle, and a polygon are used for the support column 1 and the vertical lattice 5 by forming holes at predetermined locations. It is also possible to do. Furthermore, it is also possible to use mold materials such as a U shape, a C shape, and an H shape.
[0010]
The crosspiece member 4 is a long strip plate material made of aluminum or other metal material having flexibility that can be formed into a bent shape. As shown in FIG. 3 and FIG. It is arranged on both sides of the vertical grid 5 so as to be sandwiched from both the inside and outside of the site 2 and is fixed to each vertical grid 5 with fixing tools 8 such as screws and rivets.
[0011]
As shown in FIG. 3 and FIG. 4, between the vertical lattices 5, the horizontal beam members 4 from the both sides in the inner and outer directions of the site 2 are arranged at three locations (a plurality of locations) in the vertical direction corresponding to the horizontal beam members 4. A spacer 7 is interposed so as to be covered and shielded. A core material 11 is inserted into each of the vertical lattices 5 and the spacers 7 through the through holes 9 and 10, and each vertical lattice 5 can be refracted via the spacers 7 by the core material 11 for each fence body 3. It is connected to.
[0012]
Each spacer 7 is made of a synthetic resin, and is in contact with the vertical lattice 5 around the core material 11, for example, provided with a cylindrical portion 12 in the central portion in the longitudinal direction and tapered portions 13 on both sides of the cylindrical portion 12. Both ends are tapered to reduce the area, and a longitudinal through hole 10 is formed at the center.
[0013]
Note that the maximum diameter of the central portion of the spacer 7 is such that it does not come into contact with the horizontal beam members 4 on both the inner and outer sides or lightly contacts the horizontal beam members 4 on both the inner and outer sides. However, when the spacer 7 is visible from the outside, the bent body of the fence body 3 is also configured so that the central portion of the spacer 7 contacts the inner and outer side rail members 4 within a range that does not affect the side rail member 4. It is desirable.
[0014]
The core material 11 is made of a flexible aluminum-based, stainless-based, iron-based or other metal wire that can be formed into a bent shape. The vertical lattice 5 and the spacer 7 are provided for each fence body 3. Are inserted into the through-holes 9 and 10, and both ends thereof are locked to the vertical lattices 5 at both ends by retaining portions 14 formed in a bent shape. Note that the core material 11 may be made of synthetic resin other than metal or other materials.
[0015]
At both ends of each fence body 3, the horizontal beam member 4 and the vertical lattice 5 are fixed to a fixture 6 such as a U-shape on the side of the column 1 with a fixture 8 such as a screw.
[0016]
The horizontal beam members 4 are arranged at three locations in the vertical direction of the upper end portion, the lower end portion and the middle portion of the vertical lattice 5, but are arranged at two locations, the upper end portion and the lower end portion of the vertical lattice 5. Alternatively, four or more locations may be provided. Therefore, it is sufficient if the crosspiece member 4 is at least at both the upper and lower ends of the fence body 3. The spacer 7 is provided corresponding to all of the three horizontal beam members 4, but corresponds to at least a part of the horizontal beam member 4, such as provided corresponding to the upper and lower horizontal beam members 4. Thus, it suffices if there are a plurality of vertical grids 5 in the vertical direction.
[0017]
When the fence body 3 is manufactured, a spacer 7 is interposed between the vertical grids 5, and the core material 11 is inserted into the through holes 9 and 10 of the vertical grid 5 and the spacer 7. The vertical lattice 5 is connected to bendable by the core member 11 via the spacer 7 every time.

In the case of a fence body 3 bent into an arc shape, an S shape, or the like according to the shape of the site 2 or the like, such as the left or right fence body 3 in FIG. Assembling up to the intermediate is done at the factory and shipped in the state of the intermediate. In addition, when the shape or the like of the crosspiece 4 is known, the horizontal crosspiece 4 is bent into a predetermined shape such as an arc shape or an S-shape according to the shape of the premise 2 in advance at the factory. And ship in that state. When the shape or the like of the site 2 is not known, the straight horizontal beam member 4 is carried into the construction site, and the horizontal beam member 4 is formed in a bent shape in accordance with the shape of the site 2 or the like at the construction site.

In this case, since the intermediate body has a large number of vertical lattices 5 connected to each other by the core member 11 via the spacers 7, the intermediate body can be bent along the bent shape of the horizontal beam member 4. The spacing between the lattices 5 does not change and become irregular. Further, since both ends of the spacer 7 are tapered, the bending can be easily performed even though the vertical lattice 5 is connected to the core member 11 via the spacer 7.
[0023]
After fixing one horizontal beam member 4 to each vertical grid 5, the other horizontal beam member 4 is applied to the vertical grid 5 so that the spacer 7 is sandwiched from both sides with the one horizontal beam member 4. The other horizontal beam member 4 is fixed to each vertical lattice 5 with a fixture 8. In this state, the vertical grid 5 and the horizontal beam member 4 are fixed by the fixture 8 in a state of being sandwiched between the vertical grids 5 and the horizontal beam members 4 on both sides thereof. The fence body 3 in a bent state can be easily manufactured.
