Description

[Technical Field]

[0001] The present invention relates to a mounting jig for louvers used as exterior decorations for buildings such as apartment buildings and commercial facilities. [Background technology]

[0002] A conventional mounting jig of this type is described in the following Patent Document 1 (Japanese Patent Application Laid-Open No. 2021-123958). This conventional technology is configured as follows. An installation jig for vertical louvers formed by attaching rods to a frame at predetermined intervals includes a first plate portion joined to the frame and a second plate portion joined to the rods. The first plate portion has a first flat plate portion facing the frame, and is provided at a height position approximately midway between the top and bottom of the second plate portion, with the first flat plate portion facing upward. The second plate portion has a second flat plate portion facing the rods, has a width equal to or less than the width of the rods, and is provided perpendicular to the first flat plate portion.

[0003] This technology is said to be able to provide a mounting jig for vertical louvers that can be easily attached and detached without compromising the aesthetic appearance thanks to a structure suited to the mounting location, and that has an optimized shape that minimizes the number of parts and the labor required for molding and assembly.

[0004] [Patent Document 1] Japanese Patent Publication No. 2021-123958 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above-mentioned prior art has the following problem: Because the T-shaped member is formed by joining the first plate portion joined to the frame and the second plate portion joined to the rod by welding or by integrally molding using a mold, the rod can only be attached in a predetermined manner, and it cannot be used, for example, when the frame to which the first member is attached is at an angle. In other words, there is a problem of limited flexibility in attachment. Therefore, the main object of the present invention is to provide a louver mounting jig that is not only easy to attach and remove without damaging the aesthetic appearance, but also has extremely high flexibility in attachment to the main body and louvers, making it highly versatile. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a louver mounting jig 10, which is formed by attaching louver materials 14 at predetermined intervals to the front surface of a body 12, as shown in Figures 1 to 3, and is configured as follows. Specifically, the bracket 16 includes a substantially plate-like bracket 16 joined to the frame 12, and a rectangular flat bar 18 attached to the tip of the bracket 16 with its surface joined to the back surface of the louver material 14. The tip of the bracket 16 is thickly formed, and a recessed groove 16a is formed in its surface along the entire longitudinal direction. A slit 16b is formed midway along the depth of the recessed groove 16a, with its width expanding vertically along the entire longitudinal direction and perpendicular to the recessed groove 16a. A flat bar support 20 is attached to the slit 16b. The flat bar support 20 includes a long, thin plate-like main body 20a inserted into the slit 16b and one or more female-threaded holes 20b threaded into the main body 20a at predetermined positions corresponding to the recessed groove 16a. The flat bar 18 is then screwed into the female-threaded holes 20b of the flat bar support 20.

[0007] In the present invention, the flat bar 18 is screwed into the female screw hole 20b of the flat bar holder 20 inserted into the slit portion 16b of the bracket 16, so that the angle formed by the plane of the bracket 16 and the axis of the flat bar 18 can be freely adjusted, and the louver material 14 can be installed vertically even if the mounting surface of the bracket 16 on the main body 12 is inclined. Furthermore, if multiple types of flat bar holders 20 with different numbers and positions of female screw holes 20b provided in the main body 20a are prepared, the number and arrangement of louver materials 14 that can be attached with one attachment jig 10 can be changed simply by changing the flat bar holder 20 inserted into the slit portion 16b.

[0008] In the present invention, it is preferable to form the bracket 16 from an aluminum extrusion. Here, "aluminum extrusion" refers to a shape formed by extruding a heated aluminum alloy through a die. In this case, the bracket 16 can be manufactured efficiently and economically, and the weight of the bracket 16 can be significantly reduced, so that it can be transported without using a crane or temporarily placed inside a building (frame).It can also be attached to a predetermined installation location from inside the building (frame) without erecting scaffolding or the like. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a louver mounting jig that is not only easy to attach and detach without damaging the aesthetic appearance, but also has extremely high flexibility in attachment to the main body and louvers, making it highly versatile.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an explanatory diagram showing the main components of a usage mode of a louver mounting jig 10 according to one embodiment of the present invention. As shown in this figure, the louver mounting jig 10 according to this embodiment is used to form louvers by mounting louver materials 14 at predetermined intervals on the front surface of a body 12, and generally comprises a bracket 16 and a flat bar 18.

[0012] The bracket 16 is a substantially plate-shaped metal member that is joined at a predetermined position to either the upper or lower surface of the body 12 (the lower surface in the illustrated embodiment). The portion (tip portion) of the bracket 16 at one end in the width direction, which is the tip side, is formed thick, and a concave groove 16a is formed in the surface of the thick tip portion over the entire longitudinal direction. In addition, a slit portion 16b is formed in the depth direction of the concave groove 16a, the groove width of which expands in the vertical direction over the entire longitudinal direction, and which is perpendicular to the concave groove 16a. A flat bar support 20 is attached to the slit portion 16b.

[0013] Here, the flat bar support 20 is a metal member used when vertically attaching the flat bar 18 to the tip of the bracket 16, and has a long, thin plate-like main body 20a that is inserted into the slit portion 16b (see FIG. 2). One or more female screw holes 20b are threadedly formed in the main body 20a at predetermined positions corresponding to the concave grooves 16a, more specifically, at positions that can be seen from the front through the concave grooves 16a when the main body 20a is inserted into the slit portion 16b. In the illustrated embodiment, seven female screw holes 20b are formed in the main body 20a at equal intervals in the longitudinal direction (see FIG. 3).

[0014] A plurality of elongated holes 16c are provided in the central and rear portions of the bracket 16 in the width direction, and the bracket 16 is joined to the body 12 by anchor bolts 22 inserted into these elongated holes 16c (see FIG. 1).

[0015] In addition, a horizontal surface cover 24 and a side cover 26 made of a high-strength, high-durability material such as metal or plastic are attached to the surface of the bracket 16 facing the body joint surface and to both left and right side surfaces, respectively, as needed.

[0016] When manufacturing the above-described bracket 16, there are no particular limitations on the type of metal used as the raw material or the manufacturing method, but as mentioned above, it is preferable to form the bracket 16 from an extruded aluminum profile.

[0017] The flat bar 18 is a strip of metal plate material that is hung from the tip of the above-mentioned bracket 16 and whose surface is joined to the back surface of the above-mentioned louver material 14, and its width is formed to be approximately the same as or narrower than the width of the louver material 14.

[0018] A bolt receiving hole 18a capable of receiving the head of a bolt 28 (a flat head bolt in the illustrated embodiment) is drilled slightly below the center of the surface of the flat bar 18. Therefore, by inserting the bolt 28 into the bolt receiving hole 18a and threading it into the female screw hole 20b of the flat bar holder 20, the flat bar 18 can be attached vertically to the tip of the bracket 16.

[0019] A pair of vertically long slots 18b are drilled on the surface of the flat bar 18 at the center of its width, equidistant from both the top and bottom ends in the longitudinal direction. Fixing bolts 30 are inserted through the slots 18b and engaged with bolt attachment portions 32 provided on the back side of each louver material 14, thereby joining the surface of the flat bar 18 and the back surfaces of the louver materials 14.

[0020] Next, when installing a louver using the louver mounting jig 10 configured as described above, first, the mounting angle between the bracket 16 and the flat bar 18 is adjusted depending on the shape of the body 12 to which the bracket 16 is to be mounted. For example, as shown in FIG. 3A, if the mounting surface of the body 12 to which the bracket 16 is to be mounted is horizontal, the angle between the plane of the bracket 16 and the axis of the flat bar 18 is set so that it is perpendicular, and then the bracket 16 is joined to the body 12 using anchor bolts 22. On the other hand, as shown in FIG. 3B, if the mounting surface of the body 12 to which the bracket 16 is to be mounted is inclined, the angle between the plane of the bracket 16 and the axis of the flat bar 18 is set to match the inclination, and then the bracket 16 is joined to the body 12 using anchor bolts 22. After joining the bracket 16 to the body 12 in this manner, a horizontal surface cover 24 and a side cover 26 are attached to the bracket 16 as necessary.

[0021] Then, a fixing bolt 30 is passed through the long hole on the lower side of the flat bar 18 and screwed into the bolt mounting portion 32 at the upper end of the lower louver material 14. At the same time, a fixing bolt 30 is passed through the long hole 18b on the upper side of the flat bar 18 and screwed into the bolt mounting portion 32 at the lower end of the upper louver material 14, thereby completing the attachment of the louver material 14 to the main body 12 via the attachment jig 10.

[0022] According to the louver mounting jig 10 of this embodiment, the flat bar 18 is screwed into the female threaded hole 20b of the flat bar holder 20 inserted into the slit portion 16b of the bracket 16, so that the angle formed between the plane of the bracket 16 and the axis of the flat bar 18 can be freely adjusted, and the louver material 14 can be installed vertically even if the mounting surface of the bracket 16 on the main body 12 is inclined.

[0023] Furthermore, if multiple types of flat bar holders 20 with different numbers and positions of female screw holes 20b provided in the main body 20a are prepared, the number and arrangement of louver materials 14 that can be attached with one attachment jig 10 can be changed extremely easily by simply changing the flat bar holder 20 inserted into the slit portion 16b.

[0024] In the above embodiment, the bracket 16 is joined to the lower surface of the body 12, but the bracket 16 may be joined to the upper surface of the body 12 as required. Of course, various other modifications can be made within the scope of what can be imagined by those skilled in the art. [Explanation of symbols]
