Improvement can be achieved.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings. 1A and 1B are diagrams schematically showing a blindfold fence according to an embodiment of the present invention. FIG. 1A is a front view, FIG. 1B is an enlarged sectional view taken along line AA of FIG. (A) is a front view, (b) is a bottom view, and (c) is a side view.

  In FIG. 1, reference numeral 1 denotes a blindfold fence. The blindfold fence 1 includes a pair of left and right support columns 2, a trunk edge 3 which is a structural material arranged in parallel in the left-right direction between the support columns 2, and the trunk edges. 3 is mainly composed of a lattice material 4 arranged in parallel in the longitudinal direction at a predetermined interval on the front surface of 3. The support column 2 is installed, for example, on a handrail wall of a veranda of a site or a building. The support column 2 and the trunk edge 3 are made of, for example, an extruded shape of an aluminum alloy.

  The lattice material 4 includes a pair of side frames 5 made of extruded shapes such as aluminum alloy, a transparent or translucent light transmissive material 6 interposed between the side frames 5, and end portions of the side frames 5. And an end cap 7 that covers the end of the light transmitting material 6. The both side frames 5 have a symmetrical shape. The side frame 5 has a left-right width D of about 10 mm and a front-rear depth E of about 50 mm. An engagement receiving portion 10 having a substantially C-shaped cross section is formed in the front portion of the side frame 5 by continuously forming slits 8 opened on one side surface (inner side surface) in the longitudinal direction. In addition, a tapping hole 12 for screwing a screw 11 for screwing the end cap 7 is formed in the vicinity of the slit 8. The rear side of the side frame 5 has a structure (hollow structure) having a hollow portion 13 continuous in the longitudinal direction. The side frame 5 is formed with a partition wall 14 that divides the interior in the front-rear direction, the engagement receiving portion 10 is formed on the front side across the partition wall 14, and the hollow portion 13 is formed on the rear side. The tapping hole 12 is formed in a part of the partition wall 14.

  On the other hand, the light transmitting member 6 has a plate-like solid structure, and engaging portions 15 that are slidably engaged with the engaging receiving portion 10 from the longitudinal direction are integrally formed on both sides thereof. In the case of the illustrated example, the engaging portion 15 is formed in a substantially U-shaped cross section that opens to the side, and outward ribs 16 are continuously formed on one side in the longitudinal direction. In the engagement receiving portion 10 of the side frame 5, a pair of ribs 17 that engage with both inner side portions of the front end side of the engagement portion 15 having a substantially U-shaped cross section, and an inner surface that engages with the outward rib 16. Oriented ribs 18 are formed in the longitudinal direction.

  The light transmitting material 6 is made of a synthetic resin shape, and is preferably colored, for example, light blue. The light transmissive material 6 may be transparent or translucent. Both engagement portions 15 of the light transmitting material 6 are slidably engaged from one end in the longitudinal direction to the engagement receiving portions 10 of the pair of left and right side frames 5 arranged with the slits 8 facing inward, and light is transmitted between the side frames 5. By providing the transmitting material 6, the lattice material 4 having a substantially U-shaped cross section having the light transmitting material 6 on the outer surface side is assembled. In this assembled state, the outer surface of the light transmissive material 6 has a stepped-down structure that slightly recedes inward (about 2 to 3 mm) from the front end surface of the side frame 5, thereby preventing the light transmissive material 6 from being damaged. It has become.

  As shown in FIG. 2, the end cap 7 has a main body portion 20 which is in contact with the end face of the lattice material 4 and is formed in a substantially U-shape so as to cover the end face. Are integrally formed with a fitting portion 21 fitted into the hollow portion 13 of the side frame 5 and cover portions 22 and 23 rising so as to cover the inner and outer surfaces of the end portion of the light transmitting material 6. Is formed. These cover portions 22 and 23 cover the gap generated at the end portion of the light transmitting material 6 due to the difference in thermal expansion coefficient between the side frame 5 and the light transmitting material 6. The main body portion 20 is formed with a hole portion 24 for screwing the screw 11 into the tapping hole 12 so as to screw it. The tapping hole 12 is formed in a substantially C-shaped cross section so that a portion in contact with the engaging portion 15 of the light transmitting material 6 is opened. When the screw 11 is screwed into the tapping hole 12, The screw 11 is also sunk into the engaging portion 15 of the transmissive material 6, whereby the end portion side of the light transmissive material 6 and the end portion side of the side frame 5 are coupled to each other, and the end portion of the light transmissive material is caused by the difference in thermal expansion. Is suppressed from being retracted from the end portion of the side frame 5. As shown in FIG. 1B, the lattice material 4 configured in this manner is disposed so that the rear end portion is in contact with the trunk edge 3, and screws 25 are screwed into the rear end portion from the trunk edge side. Is fixed to the trunk edge 3.

  According to the blindfold fence 1 configured as described above, the trunk edge (structural material) 3 disposed in parallel in the left-right direction and the front surface of the trunk edge 3 are disposed in parallel in the longitudinal direction at predetermined intervals. The lattice material 4 includes a pair of side frames 5 made of a shape material, a transparent or translucent light transmissive material 6 interposed between the side frames 5, and ends of the side frames 5. And an end cap 7 that covers the end of the light-transmitting material 6 and can improve the light transmittance, achieve a bright interior with a sense of openness, and improve the appearance design. Can be planned. That is, in the case of the lattice material 4, when the width D of each side frame is 10 mm, the width F between both side frames to which the light transmitting material 6 is mounted is 30 mm, and the width of the entire lattice material 4 is 50 mm, the lattice material 4 is When arranged at a pitch of 100 mm so that there is a clearance S of about 50 mm (see FIG. 1), the light transmittance is 80%, and the light transmittance is lower than that of a conventional blindfold fence with a light transmittance of 50%. It can be improved by 60%.

  Further, an end cap 7 is attached to the end portion of the lattice material 4, and the end cap 7 has cover portions 22 and 23 that cover the inner and outer surfaces of the end portion of the light transmitting material 6. The expansion and contraction of the end of the light transmitting material 6 and the roughness of the cut surface can be covered, and the design can be improved. In the lattice material 4, due to the composite structure of aluminum and resin, a difference in expansion and contraction tends to occur between the side frame 5 and the light transmission material 6 due to heat and cold, but it is screwed into the tapping hole 12. Since the two members of the side frame 5 and the light transmissive material 6 are coupled with the screw 11 and the three members of the end cap 7, the side frame 5 and the light transmissive material 6 are screwed simultaneously, the side frame 5 and the light Deviation of the end portion of the transmission material 6 can be prevented. In addition, since the light transmitting material 6 has a solid shape, chips at the time of cutting can be easily removed.
