[0008]

FIG. 1 shows a front view of an example of a synthetic resin fence containing wood flour according to the present invention. This synthetic resin fence containing wood flour has a plurality of panel bodies 2 arranged between columns 1 standing on the ground at predetermined intervals.

The column 1 is formed of a metal (for example, aluminum) in the shape of a quadrangular cylinder, and is engaged with the lower end of the vertical bar 3 of the panel body 2 on both sides below. Metal fittings 4 are screwed.

The panel body 2 forms a rectangular frame 7 by forming upper and lower body edges 5 and 6 and left and right vertical rails 3 in a rectangular shape, and a horizontal lattice forming a blind panel inside the rectangular frame 7. As shown in FIGS. 2 and 3, the upper body edge 5 and the lower body edge 6 are each formed in a substantially C-shaped cross section, and the upper body edge 5 is located below and the lower body edge is provided. 6 is open upward. Also, core members 11 and 12 made of extruded aluminum members are inserted into the upper body edge 5 and the lower body edge 6, respectively.
Screw holes 10 are formed in 1 and 12, respectively. The core members 11 and 12 are formed with concave grooves 13 and 14. Saw-toothed uneven portions 15 are formed on the inner surfaces of the concave grooves 13 and 14.

The vertical bar 3 is also basically C-shaped in cross section and has a concave groove 16 formed on the back surface. A metal core 17 made of aluminum or the like is provided along the inner surface. On the inner surface of the concave groove 16, a serrated uneven portion 15 is formed.

The vertical rails 3 on both sides are arranged so that the concave grooves 16 are opposed to each other.
6 are fixed to the screw holes 10 of the core members 11 and 12, thereby forming a rectangular frame 7 in which the upper body edge 5 and the lower body edge 6 are connected to the left and right vertical rails 3; Continuous concave grooves 13, 14, 16 are formed on the inner peripheral surface.

Next, as shown in FIG. 3, the horizontal lattice 8 is a hollow body having a parallelogram-shaped cross section, and a hollow material 19 is provided with a core material 20 made of extruded shape such as aluminum and inserted in the center. Has a screw hole 21 formed therein. The horizontal lattice 8 is press-fitted into the concave groove 13 of the vertical bar 3 of the rectangular frame, and is fixed by fastening a screw 22 inserted from the outside of the vertical bar 3 to the screw hole 21 of the core 20. . Note that a vertical lattice may be used instead of the horizontal lattice.

The panel body 2 formed as described above
Is attached to the column 1 erected at regular intervals, the opening 23 of the vertical bar 3 is fitted to the upper end of the column 1,
Further, it is lowered along the support 1 until the lower end of the vertical bar 3 hits the support 4 fixed to the support 1. When the panel body 2 is supported by the support fitting 4, a cap 26 is put on the column 1 so as to cover the upper end of the vertical bar 3, and a mounting piece 27 formed on the cap 26 is screwed to the column 1.
What is necessary is just to fix to the support | pillar 1 so that the panel body 2 may be pinched from above and below by the support fitting 4 and the cap 26. FIG.

In the groove 13 of the vertical rail 3, a serrated uneven portion 15 is provided.
Is formed, when the end portion of the horizontal lattice 8 is press-fitted, the concave-convex portion 15 bites into the side surface thereof, and there is no rattling or noise even when receiving the wind pressure.

Further, since the metal column 1 is covered by the vertical bar 3 of the two adjacent panel bodies 2, it is not exposed to the outside, so that the appearance as a wooden wind fence is not impaired.

The vertical bar 3, the rims 5, 6 and the horizontal grid 8 are each formed of a synthetic resin mixed with wood flour. Since wood flour is obtained by pulverizing natural wood, the wood flour can be expressed by the wood flour by a special treatment at the time of extrusion molding. In addition, since wood flour reflects light irregularly, there is no sense of shrinkage as compared with paint or printing on a metal surface. Therefore, the overall texture and texture are almost the same as those of natural wood,
The appearance of the fence constituted by 5, 6, and 8 is so realistic that it is mistaken for natural wood.

Further, since the above-mentioned components are manufactured by extrusion molding, they have the same shape and the same dimensions, are stable in quality, can be mass-produced at low cost, and can be constructed and assembled. Becomes easier.

Further, since the panel body 2 is made of a synthetic resin, warpage or cracking does not occur due to aging as compared with actual wood, and furthermore, if the surface of the panel body is crushed or frayed like a wood, a file is made. Maintenance work such as clinging and regular painting is not required.

Next, FIG. 4 shows an example in which the lattice is a cross lattice, and the vertical rail 3 and the rims 5 and 6 are the same as those in FIG. This panel body 2 is obtained by intersecting grids 28a and 28b at predetermined intervals, and as shown in FIGS. 5 and 6, a hollow synthetic resin core material 30 is provided in the hollow portion. 2
8a and 28b are adhered to each other with an adhesive, and the ends of the grids 28a and 28b are overlapped with the concave groove 16 of the vertical rail 3 and the core material of the body edges 5 and 6. 1
It is constituted by press-fitting into the concave grooves 13, 14 formed in the grooves 1, 12 and press-contacting the saw-tooth irregularities 15 formed in the concave grooves 13, 14, 16.

A metal receiving plate 31 for receiving the end surface of the body edge is provided on each of the upper and lower portions of the vertical bar. Although it is not provided along the entire inner length of the vertical bar 3, the column 1 supporting the vertical bar 3 is made of high-strength metal, so that the vertical bar 3 can be supported with sufficiently high strength. it can.

[0022]

According to the first aspect of the present invention, each of the vertical rail, the body edge, and the horizontal lattice are formed of a synthetic resin mixed with wood flour. Since wood flour is obtained by pulverizing natural wood, the wood flour can be expressed by the wood flour by a special treatment at the time of extrusion molding. In addition, since wood flour reflects light irregularly, there is no sense of shrinkage as compared with paint or printing on a metal surface. Therefore, the overall texture and texture are almost the same as those of natural wood, and the appearance of the fence constituted by the above-mentioned components is almost as wrong as natural wood.

Further, since the above-mentioned constituent members are manufactured by extrusion molding, they have the same shape and the same dimensions and the quality is stable, so that the panel body can be integratedly manufactured at the factory and the production efficiency can be improved. it can.

Further, since the panel body is made of synthetic resin, warping or cracking does not occur due to aging as compared with actual wood, and moreover, if the surface is crushed or sanded like wood, the file is not sanded. Maintenance work such as shaking and regular painting is not required.

According to the second aspect of the present invention, since the serrations are formed on the inner wall of the groove, when the end of the lattice is inserted into the groove, the edge and the irregularity of the groove are formed. Since the parts are tightly pressed, the lattice does not rattle in the rectangular frame after the construction, and no noise is generated even when receiving a strong wind pressure.

According to the third aspect of the present invention, the lattice is a vertical lattice or a horizontal lattice, and a screw hole is formed along the longitudinal direction of the core material. The grid can be firmly fixed by fixing it to the screw holes of the core material.
