Description

[Technical field]

[0001] The present invention relates to a horizontal lattice louver that is provided at a predetermined distance from an opening such as a window, primarily in an alcove of a building. [Background technology]

[0002] One of the effective ways to create a beautiful façade of a building is to beautifully cover up the parts that cannot be seen. Such a method involves hiding poorly placed windows with screens, or, if on the first floor, hiding them with trees. Of course, it is necessary to be mindful of creating a beautiful façade without covering them up, but there are many cases where the appearance is ruined by window placement that prioritizes life and outdoor hoods and window shutters that are necessary to ensure performance. One way to create such a beautiful façade is to install horizontal lattice louvers in front of windows installed in alcoves, balconies, etc. of a building. For example, in the building shown in Reference 1, horizontal lattice louvers are disclosed, which are made by fixing a frame to which multiple horizontal slats are fixed at equal intervals in the vertical direction to the opposing surfaces of the building body and a supporting wall separated from the building body. The frame is fixed to the two walls by fixing both ends of the frame to brackets attached to the walls. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-106515 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, according to the above-mentioned conventional technology, a vertical frame with multiple horizontal slats attached at equal intervals is connected in the vertical direction by fixing both ends of the multiple horizontal frames to brackets on the wall. This type of installation improves ventilation, but if the horizontal slats are configured to be inclined downward toward the interior so that the inside cannot be seen from the outside, they must be fixed to the vertical frame at equal intervals with an inclination angle. However, there is a problem in that it is difficult to install in this way while maintaining the aesthetic appearance from the outside.

[0005] In view of the above circumstances, the present invention has been made with an object to provide a horizontal lattice louver which can be easily installed while maintaining an inclination angle and which also maintains a beautiful appearance from the outside. [Means for solving the problem]

[0006] The horizontal lattice louver of the present invention for achieving the above object comprises a mounting frame fixed vertically along two opposing wall surfaces of a building, a lattice fixing frame fixed along the mounting frame, and a plurality of horizontal lattices fixed at both ends to the lattice fixing frame with an interval in the vertical direction. A horizontal lattice louver that The lattice fixing frame extends from the lattice fixing frame in the inclined direction so as to fix the end of the horizontal lattice at an angle in the inclination direction of the horizontal lattice. The horizontal grid has a plurality of lattice mounting pieces, each of which is formed so that its upper end is lower than the lower end of the next upper lattice mounting piece, and both ends of the horizontal grid are fixed to the lattice mounting pieces. The point is...

[0007] The mounting frame is connected and fixed to the structure of the building via connecting metal fittings. The horizontal lattice is a long member with a rectangular cross section. The horizontal lattice is inclined downward toward the indoor side of the building. The lattice fixing frame is a long member with a substantially L-shaped cross section, equipped with a fixing piece fixed to the mounting frame and a support plate having a plurality of the inclined lattice mounting pieces spaced equally apart in the vertical direction. The lattice fixing frame is divided into a plurality of pieces and fixed to the mounting frame in the vertical direction. Effect of the Invention

[0008] In addition to retaining the original function of horizontal lattice louvers, which is to allow good ventilation and block direct sunlight, the horizontal lattice louvers are installed in an inset manner on two opposing wall surfaces of a building, so both side portions of the horizontal lattice louvers are hidden by the wall and cannot be seen from the outside, preserving the beauty of the entire building. Also, the lattice mounting pieces attached to the support plate of the lattice fixing frame that fixes both ends of the horizontal lattice are inclined to the lattice fixing frame to be the same as the inclination angle of the horizontal lattice, so there is no need to adjust the vertical spacing or angle of the horizontal lattice during installation, allowing for quick and accurate installation, and the posture can be maintained stably after installation.

[0009] The mounting frame is fixed to the structure of the building via metal fittings, making it very stable. Since the cross section of the horizontal lattice is rectangular, when it is fixed to the lattice mounting piece at an angle, even if the horizontal lattice is tilted towards either the indoor or outdoor side, when viewed from outside the building, the top or bottom and two sides of the horizontal lattice can be seen regardless of the viewing angle, which results in an excellent design.

[0010] When the horizontal lattice is inclined downward toward the indoor side, the line of sight can be blocked so that the indoor side cannot be seen when viewed from the front or below outdoors. When the lattice fixing frame is a long member with a substantially L-shaped cross section, which includes a fixing plate fixed to the mounting frame and a support plate having a plurality of the inclined lattice mounting pieces at equal intervals in the vertical direction, it can be attached vertically along the mounting frame simply by fixing the fixing plate to the mounting frame, and since the support plate and the lattice mounting pieces formed on this support plate are perpendicular to the mounting frame, the installation work is simple and the aesthetic appearance can be maintained after installation. When the lattice fixing frame is fixed to the mounting frame in multiple parts in the vertical direction, the joints are not visible from the outside, so each lattice fixing frame is lighter while maintaining the aesthetic appearance, making it easier to install and transport the lattice fixing frame to the mounting frame.

[0012] An embodiment of the horizontal lattice louver of the present invention will be described below with reference to the drawings. As shown in Figures 1 to 3, the horizontal lattice louver 1 of the embodiment of the present invention is inset at a specified distance from the outside of a window 5 of a room on the indoor side of an alcove portion 4 sandwiched between walls 3 near a protruding corner on the second floor of a building 2.

[0013] As shown in Figures 4 and 5, the horizontal lattice louver 1 of this embodiment is installed between two opposing inner wall surfaces 3B of an opening slightly recessed from the outer wall surface 3A of the building 2 that forms both sides of the alcove portion 4, with a distance D between it and the window 5. The horizontal lattice louver 1 is attached vertically along the inner wall surface 3B, as shown in Figure 6, by a mounting bracket 7 fixed at one end to the building structure 6 of the building 2, which penetrates the inner wall surface 3B and is fixed to a mounting frame 9 that is screwed and fixed to the other end protruding into the opening closer to the window 5 side than the outer wall surface 3A by a screw 8 so as to be parallel to the vertical direction along the inner wall surface 3B. Since this mounting frame 9 is a member that is long in the vertical direction, it is fixed to the building structure 6 by the mounting bracket 7 so as to maintain the vertical direction at least at two or more points in the vertical direction.

[0014] The horizontal lattice louver 1 is fixed to this mounting frame 9, but if it is long vertically it becomes heavy and difficult to attach and remove, so it is divided into several pieces and fixed, but when lightweight materials are used or it is small, a single piece is used. The basic structure of this divided horizontal lattice louver 1A and the entire horizontal lattice louver 1 before being divided, as can be seen clearly in Figure 7, is a pair of left and right lattice fixing frames 10 fixed to the mounting frame 9, and several horizontal lattices 11 fixed to these lattice fixing frames 10 at intervals in the vertical direction.

[0015] As shown in FIG. 9, the lattice fixing frame 10 is a vertically long member with a substantially L-shaped cross section, and includes a fixing plate 10a to be fixed to the mounting frame 9 and a support plate 10b to support the horizontal lattice 11. The support plate 10b is provided with lattice mounting pieces 10c inclined upward at a predetermined angle at equal intervals. The upper end of the lower lattice mounting piece 10c is slightly lower than the lower end of the lattice mounting piece 10c above it, so that the shaft of a fastening tool such as a screwdriver that screws in a fastener K such as a screw that fixes the fixing plate 10a to the mounting frame 9 from the outdoor side can be inserted. Each lattice mounting piece 10c is provided with two screw holes 10d in the vertical direction for fixing the horizontal lattice 11. Conversely, if the inclination angle of the lattice mounting piece 10c is inclined downward toward the outdoor side, the horizontal lattice 11 can be installed so that it descends toward the outdoor side of the building 2. In addition, in this embodiment, the lattice mounting pieces 10c are attached in a comb shape to the support plate 10b, but if the fixed plate 10a is strong, the support plate 10b can be eliminated and the lattice mounting pieces 10c formed to protrude from the longitudinal edge of the fixed plate 10a can be folded at right angles so that the folded lattice mounting pieces 10c are formed in a comb shape that is inclined toward the indoor side.

[0016] The horizontal lattice 11 is a horizontally long metal member with a rectangular cross section and a hollow interior as shown in FIG. 10, and end plates 11b with two screw holes 11a in the vertical direction are fixed to both ends. Instead of metal, it may be made of synthetic resin or wood, and there is no limitation on the material. The interior is hollow to make it lighter, but if the horizontal lattice 11 is a small and lightweight member, it may be solid inside. In the case of a rectangular cross section as in this embodiment, if the horizontal lattice 11 is inclined downward toward the indoor side, the lower surface and side surface in the longitudinal direction of the horizontal lattice 11 can be seen when viewed from the front side or from below the outside of the building 2, so that it can be varied in design. In addition, the wind blowing from the outside is passed toward the indoor direction along the side of the horizontal lattice 11 inclined downward toward the indoor side, which improves ventilation. Even if the cross section is a shape other than a rectangle, it will look good from the outside. To In addition, there are no particular limitations as long as the material is well ventilated and blocks sunlight.

[0017] As shown in Figure 12, the horizontal lattice 11 is fixed to the support plate 10b by aligning the end plate 11b of the horizontal lattice 11 with the lattice mounting piece 10c, aligning the two screw holes 10d and 11a on both sides, and fastening them with screws 12. In this way, both ends of the horizontal lattice 11 are fixed to the lattice mounting piece 10c, i.e., the support plate 10b, and the distance between the two lattice fixing frames 10 is determined by the length of the horizontal lattice 11. Once all the horizontal lattices 11 have been fixed to the lattice mounting piece 10c in this way, the horizontal lattice louver 1 is assembled and completed.

[0018] The horizontal lattice louver 1 assembled as described above is fixed to a mounting frame 9 that is attached in advance to the inner wall surfaces 3B of two opposing walls 3 of a building 2, as shown in Figures 1 and 2. This mounting is performed by aligning the fixing plate 10a of the lattice fixing frame 10 along the mounting frame 9, aligning the screw holes formed on both sides, and then fastening and fixing with a fastener K such as a screw, as shown clearly in Figures 6, 8, and 11. When fastening, a screwdriver that rotates the fastener K while pressing it is inserted from the outdoor side through the gap between the horizontal lattices 11 adjacent above and below, and to make this possible, as described above, a slight gap is created in the horizontal direction between the lower end of the upper horizontal lattice 11 and the upper end of the lower horizontal lattice 11.

[0019] In the case of the horizontal lattice louver 1, the length of the lattice fixing frame 10 is set to match the length of the mounting frame 9 so that one louver can cover the vertical height of the alcove 4 to be installed. If all the components are made of metal, the weight makes it difficult to assemble on-site and also makes it difficult to transport from the factory to the installation site, so the louver is divided and fixed to the mounting frame 9. The number of parts to be divided is arbitrary, but in this embodiment, it is divided into four. If the interval between the divided upper and lower horizontal lattice louvers 1A is the same as the interval between the upper and lower horizontal lattices 11, the joints will not be noticeable from the outside and the beauty can be maintained. In addition, if the support plate 10b having the lattice mounting piece 10c that fixes the horizontal lattice 11 is fixed to the mounting frame 9 so that it is hidden behind the horizontal lattice 11, the head of the fixing tool K used for fixing it will not be visible from the outside, and the beauty will not be impaired. When the divided horizontal lattice louver 1 is fixed to the mounting frame 9, it is fixed with the fixing tool K at two points, the top and the bottom.

[0020] As is clear from the above explanation, with the horizontal lattice louver 1 of this invention, the horizontal lattice louver 1 can be assembled in advance at a factory, transported to the installation site and installed, improving work efficiency. Moreover, it can be separated in the vertical direction, making installation and transportation easier. Also, it is only necessary to form the lattice mounting pieces 10c provided on the support plate 10b of the lattice fixing frame 10 according to the previously designed installation interval, inclination direction and inclination angle of the horizontal lattice 11 in the vertical direction, which simplifies assembly work in the factory and improves accuracy. [Industrial Applicability]

[0021] The horizontal lattice louver 11 of this invention can be installed not only in alcoves and verandas on the north side of a building where it is difficult to expect natural lighting, but also in storerooms, toilets, and corridors. When used in a living room, it can be used with a separate window, or the depth of the alcove can be used to hide a swing sash or ventilation hood, so it has a wide range of applications. Furthermore, if the orientation is reversed, it becomes a horizontal lattice louver with lattices that incline toward the outdoors, and if it is turned at a right angle, it can also be used as a vertical lattice louver.
