Patent Document 1 discloses an architectural exterior louver in which long louver panels formed at right angles to each other are arranged in a horizontal or vertical row on a base material attached to the building frame, and end hiding members that cover the ends of the louver panels are placed near the ends of the corners, with mounting parts provided on the backs of these end members fixed to the end hiding members on the backs of the adjacent louver panels.

JP 2007-138430 A

However, in architectural exterior louvers such as those described above, the corners are made up of louver panels with right angles, so there is a gap between the louver panels at the corners, which mars the aesthetic look, and although edge covering members are placed near the edges of the louver panels at the corners, there is also a gap between the louver panel and the edge covering member, which mars the aesthetic look. In addition, rainwater and debris can easily get into the inside of the louver panel body through this space, making it difficult to use.

The objective of the present invention is to solve the above problems, improve the design between louver materials arranged in the corners of a building structure, and provide an easy-to-use structure for closing the ends of architectural louvers.

The present invention has been made to solve the above-mentioned problems and has the following features.
The invention described in claim 1 is an architectural louver in which a plurality of louver materials having hollow portions are arranged horizontally or vertically on mounting members attached to a building structure, and the louver materials are arranged in a row with gaps between them vertically or horizontally, and at the corners of the building structure, the end faces of the louver materials are butted together to form an outside corner or an inside corner, and a small-edge decorative material that covers the small edge is attached to the end faces of the louver materials, and the small-edge decorative material is screwed to the back side of the louver material via a support bracket, and the support bracket is attached to the back sides of the small-edge decorative material and the louver material .

An embodiment of the present invention will be described with reference to the drawings.

The end closing structure 10 for architectural louvers according to this embodiment is, as shown in Figure 1, a structure in which multiple long louver materials 20 are arranged horizontally or vertically on a building structure 51 such as a wall, and are arranged in a row with gaps between them vertically or horizontally. The louver materials 20 are each formed by fixing long mounting members 52 to multiple mounting members 53 fixed to the building structure 51, and further fixing multiple louver materials 20 to the mounting members 52.

When arranging the louver materials 20 horizontally, as shown in Figures 1 and 2, multiple mounting members 53 are fixed vertically to the building frame 51 with bolts 54, and mounting members 52 are fixed to the multiple mounting members 53 with bolts 55, and then these are arranged in a row with gaps between them. The louver materials 20 are then attached so as to span between the multiple mounting members 52. To arrange the louver materials 20 vertically, multiple mounting members 53 are fixed horizontally to the building frame 51 with bolts 54, and these mounting members 52 are fixed to the multiple mounting members 53 with bolts 55, and then these are arranged in a row with gaps between them, and then the louver materials 20 are attached so as to span between the multiple mounting members 52 (not shown).

As shown in FIG. 2, the louver materials 20 are configured to butt the end faces of adjacent louver materials 20 together at corners that are either protruding or recessed corners of the building structure 51, and to run along the building structure 51. The end faces of the louver materials 20 are provided with edge decorative materials 30 that cover the edges.

First, the first embodiment will be described with reference to FIGS.
The louver material 20 is arranged on a building framework 51 such as a wall, as shown in Fig. 1. The louver material 20 according to this embodiment is made of an extruded material as shown in Fig. 2, and as shown in Figs. 3 and 5, a hollow portion 21 is formed of an upper side portion 23 and a lower side portion 24 that connect a pair of side portions 22 (decorative sides) at the top and bottom, and a pair of side portions 26 (mounting sides) having an L-shaped cross section that connects downward from the pair of side piece portions 22, and a dovetail-shaped mounting portion 25 is formed on the inside of the side portions 26 on both sides, and a receiving metal fitting 28 is arranged inside the mounting portion 25, and a female screw is formed in the receiving metal fitting 28.
The louver material 20 is fixed by screwing the bolt 29 inserted from the mounting member 52 into the receiving metal fitting 28. As a result, a plurality of louver materials 20 are arranged horizontally on the mounting member 52. Then, end decorative materials 30 that close the end of the louver material 20 are attached to both ends of the louver material 20. Also, as shown in FIG. 2, the end faces of adjacent louver materials 20 arranged in a corner portion consisting of an external corner or an internal corner of the building structure 51 are butted together and cut to have an acute angle. The end faces cut at an acute angle differ depending on the angle of the building structure 51, but are preferably inclined at 30 degrees to 89 degrees so as to follow the building structure 51. Also, as shown in FIG. 2, a narrow space S is formed between the end faces of the butted louver materials 20.

As shown in FIG. 5, the louver material 20 has a pair of upper and lower protrusions 27 formed along the longitudinal direction of the opposing inner wall surfaces of the hollow portion 21. The protrusions 27 are formed in an arc-shaped cross section, and have a groove formed in the center. Note that the protrusions 27 do not have to be a pair on the upper and lower sides, and may be located in only one place on the lower side 24 side (not shown).

Next, the edge decorative material 30 will be described.
As shown in Fig. 3, the edge decorative material 30 is made of a metal such as aluminum and has the same rectangular shape as the external shape of the cross section of the louver material 20, and as shown in Fig. 6(a) and Fig. 6(b), a pair of fitting pieces 31 are formed to protrude parallel to each other slightly above the center of the back surface 30B side. The fitting pieces 31 are plate-shaped and are formed at positions where they can fit into the protrusions 27 of the louver material 20 when the edge decorative material 30 is placed against the edge of the louver material 20, and the distance between the tips of the pair of fitting pieces 31 is formed to be slightly smaller than the width of the protrusions 27. In addition, the edge decorative material 30 attached to the louver material 20 arranged at the corner portion of the building frame 51 has a guide portion 31a that does not have a right angle at the upper corners of the pair of fitting pieces 31 and is inclined toward the decorative surface 30A side of the edge decorative material 30. Specifically, as shown in FIG. 4, when the edge decorative material 30 is attached to the louver material 20, the upper side portion 23 of the louver material 20 and the guide portion 31a are inclined at an angle so as to be parallel to each other.

An engagement portion 32 is formed at the bottom of the engagement piece 31. As shown in FIG. 6(b), the engagement portion 32 is made up of two engagement pieces with tips bent inward, and a space is formed on the inside large enough for a screw 34 to be inserted. In addition, the edge decorative material 30 attached to the louver material 20 arranged at the corner of the building structure 51 has a distance between the engagement piece 31 and the engagement portion 32 that is large enough not to come into contact with the bottom edge portion 24 of the louver material 20, as shown in FIG. 4.

As shown in Figures 2 and 4, the support bracket 33 is a bracket for attaching the edge decorative material 30 to the louver material 20 arranged at the corner portion of the building structure 51. As shown in Figures 7(a) and 7(b), the support bracket 33 in this embodiment has an approximately V-shaped cross section and an approximately T-shaped plan view, and is composed of a lid receiving piece 33a attached to the engagement portion 32 of the edge decorative material 30 and a louver receiving piece 33b attached to the lower side portion 24 of the louver material 20.

When attaching the edge decorative material 30 of the above configuration to the edge of the louver material 20 arranged in a corner portion, first, the lid receiving piece 33a of the support bracket 33 shown in Figures 7(a) and 7(b) is screwed and fixed with a screw 34 as shown in Figure 4, passing through the inside of the engagement part 32 of the edge decorative material 30 shown in Figures 6(a) and 6(b). The tip of the engagement part 32 is bent inward to embrace the screw 34, so that the edge decorative material 30 is securely fixed to the support bracket 33 by the screw 34. The protrusion 27 of the louver material 20 is pushed into and fixed between the fitting pieces 31 of the edge decorative material 30 so that it fits in. At this time, the guide portion 31a of the fitting piece 31 fits into the protrusion 27 of the louver material 20, which is inclined at an acute angle, and the guide portion 31a enters the hollow portion 21 of the louver material 20 along the protrusion 27 until the back surface 30B side of the edge decorative material 30 abuts against the end face of the louver material 20. Furthermore, as shown in FIG. 2, a screw 35 is inserted between the side portions 26 on both sides of the dovetail-shaped mounting portion 25 provided on the back surface side 20B of the louver material 20, and the bottom portion 24 of the louver material 20 and the louver receiving piece 33b of the support bracket 33 are screwed and fixed with the screw 35. The screw 35 is fixed in a state of being pressed against the bottom portion 24.

As described above, at the corners of the building structure 51, the end faces of the louver materials 20 butt against each other to form an outside corner or an inside corner, and end decorative material 30 that covers the end is attached to the end face of the louver material 20, so that the louver materials 20 are connected at the corners with only a narrow space S between them, providing an architectural louver end covering structure 10 with excellent design.

In addition, the butted end faces of the louver material 20 are cut at an acute angle, so the louver material 20 conforms to the building structure 51 at the corners, providing excellent design. In addition, the end decorative material 30 is attached to each end face by fitting, making the work easy and providing excellent design, as there are no fasteners such as screws on the decorative surface 30A. In addition, the tip of the louver material 20, which is cut at an acute angle, is sharp, so by sealing the end with the end decorative material 30, the sharpness of the tip is reduced, preventing the risk of injury from hitting the corners.

In addition, a protrusion 27 is formed along the longitudinal direction inside the hollow portion 21 of the louver material 20, while a pair of fitting pieces 31 corresponding to the protrusions 27 are formed protrudingly on the back surface 30B side of the edge decorative material 30, and the pair of fitting pieces 31 are provided with guide portions 31a that fit into the protrusions 27. Therefore, the guide portions 31a ensure that the edge decorative material 30 will not easily come off even when the end face of the louver material 20 is cut at an acute angle, and it can be securely fixed in place.

In addition, the edge decorative material 30 is screwed to the back surface 20B side of the louver material 20 via the support brackets 33, and is therefore screwed to the back surface 20B side which is difficult to see, resulting in excellent design.

The louver material 20 and edge decorative material 30 may be decorated on the decorative surfaces 20A and 30A to improve their design.

Second Embodiment Next, an end closing structure 10' for an architectural louver according to a second embodiment will be described with reference to FIGS.
The embodiment of Example 2 is a configuration in which the decorative surfaces 20A and 30A of the embodiment of Example 1 are decorated, as shown in FIG. 8. That is, as shown in FIG. 9(a) and FIG. 10(a), the louver material 20' and the edge decorative material 30' may have decorative surfaces 20A' and 30A' in which a wood grain pattern or a straight grain pattern is formed in the extrusion direction on the decorative surfaces 20A and 30A of the louver material 20 and the edge decorative material 30 during extrusion. Also, as shown in FIG. 10(c), the edge decorative material 30" may have a decorative surface 30A" formed in a direction intersecting the extrusion direction (in the embodiment, a direction inclined with respect to the extrusion direction) during extrusion. Note that, as shown in FIG. 9(b), FIG. 10(b), and FIG. 10(d), by forming the uneven patterns of the decorative surfaces 20A', 30A', and 30A" unevenly during extrusion, a realistic feeling close to an actual wood grain pattern or a straight grain pattern can be expressed, and therefore the design is extremely excellent.

As mentioned above, the wood grain or straight grain pattern is formed simply by extrusion, eliminating the need for post-processing and improving productivity.
