Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above-described conventional louvers, techniques and time were required to make the respective decorative surfaces (front surface, side surface, etc.) of the louver different colors or patterns. For example, when attaching different decorative sheets to the respective decorative surfaces of the louver, it was necessary to attach the decorative sheets so that the boundaries at the corners did not protrude and no gaps were generated, which required both technique and labor. Further, when painting the respective decorative surfaces different colors or patterns, it was necessary to perform the work after curing the boundaries at the corners with masking tape or the like so that the paint did not protrude, resulting in poor workability and time consumption.

[0005] Therefore, an object of the present invention is to provide an architectural louver that can be easily and quickly worked even when different colors and patterns are desired for each decorative surface (front surface and side surface) of the louver.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention is an architectural louver that is attached so as to project from a wall surface or a ceiling surface of a building body. When the projecting direction of the architectural louver is forward, it includes a second louver material having a pair of side wall portions, and a first louver material fixed inside the pair of side wall portions of the second louver material. The front surface of the first louver material constitutes the decorative front surface of the architectural louver, and the pair of side wall portions of the second louver material constitute the decorative side surfaces of the architectural louver.

Effects of the Invention

[0007] As described above, the present invention has the front surface of the first louver material constituting the decorative front surface of the architectural louver, and the pair of side wall portions of the second louver material constituting the decorative side surfaces of the architectural louver. That is, the decorative front surface and the decorative side surfaces are configured with different members. According to such a configuration, before combining the first louver material and the second louver material, it is possible to separately attach a decorative sheet, perform an anodizing treatment or painting on the decorative front surface and the decorative side surfaces. Therefore, even when different colors and patterns are desired for each decorative surface (front surface and side surface) of the louver, it is possible to work easily and in a short time without the need for special techniques or much labor.

[0008] In addition, since the architectural louver is completed simply by combining the first louver material and the second louver material, which are separately colored or patterned, during construction, the assembly work is also easy.

Embodiments for Carrying Out the Invention

[0010] Embodiments of the present invention will be described with reference to the drawings. In the following description, the protruding direction of the building louver 10 (the direction perpendicular to the construction surface. The left direction in FIG. 2) is taken as the front, and the opposite direction (the right direction in FIG. 2) is taken as the rear.

[0011] The building louver 10 according to this embodiment is a long member that is attached so as to protrude from the wall surface or ceiling surface of the building body 50. For example, as shown in FIGS. 1 and 2, a plurality of building louvers 10 can be attached to the surface of the building body 50 in parallel to each other. This building louver 10 is a hollow long member. The building louver 10 is formed in a quadrangular prism shape and has four surfaces in the longitudinal direction. Among these, the rear surface is in contact with the building body 50 and is fixed to the building body 50. Also, the front surface is a decorative front surface 10a that is exposed to the outside. Further, the remaining two side surfaces (side surfaces in the longitudinal direction) are decorative side surfaces 10b that are exposed to the outside. Note that the side surface in the short direction is the end face of the building louver 10. Although not particularly shown, a lid or the like may be attached to this end face. Also, the above-described decorative front surface 10a and decorative side surface 10b are perpendicular to each other and are continuous at the corner portion 10c. This building louver 10 includes, as constituent parts, a first louver material 11 and a second louver material 20.

[0012] The first louver material 11 is a long member made of metal, for example, an extruded shape made of aluminum. This first louver material 11 has the same shape over the entire length and is formed in the cross-sectional shape shown in FIG. 3. This first louver material 11 has a substantially U-shaped cross-section and includes a front piece 12 on the front side and insertion pieces 13 that extend rearward from both ends of the front piece 12.

[0013] The front surface 12a (surface) of the front piece 12 constitutes the decorative front surface 10a of the building louver 10. The front surface 12a according to this embodiment is a flat surface without unevenness. Also, both end portions of the front piece 12 have a shape that slightly protrudes laterally, and a butting portion 12b is formed on the rear surface of this protruding portion. This butting portion 12b is a portion that abuts against the front end 22a of the side wall portion 21 described later. The butting portion 12b is an inclined surface that is inclined at about 45 degrees with respect to the front surface 12a, in other words, is formed so as to form an acute angle of about 45 degrees with the front surface 12a.

[0014] The insertion piece 13 is a part fixed inside a pair of side wall parts 21 described later. The insertion pieces 13 are provided in a pair on the left and right, and protrude in a direction orthogonal to the front piece 12. The insertion piece 13 is formed so as to be continuous from the abutting part 12b. The insertion piece 13 according to the present embodiment is inserted between the pair of side wall parts 21 from the front, and is engaged and fixed with the second louver material 20.

[0015] A ridge 14 extending in the longitudinal direction is formed on the outer surface 13a of the insertion piece 13. The ridge 14 is for engaging an engaging part 22 described later. The ridge 14 is formed to protrude laterally from the outer surface 13a of the insertion piece 13, and includes a vertical surface 14a, an engaging surface 14b, and a guiding surface 14c. The vertical surface 14a is the front surface of the ridge 14 and is perpendicular to the outer surface 13a. The engaging surface 14b is a surface continuous from the end of the vertical surface 14a and is parallel to the outer surface 13a. The guiding surface 14c is a surface continuous from the end of the engaging surface 14b and is an inclined surface connecting the end of the engaging surface 14b and the outer surface 13a. A fitting groove 15 is recessed in front of the ridge 14 and is sandwiched between the vertical surface 14a and the abutting part 12b. The fitting groove 15 is a recess for fitting a protrusion 22c described later. When the protrusion 22c is fitted into the fitting groove 15, the side wall part 21 and the insertion piece 13 are fixed so as not to fall off. Further, screw holes 16 are formed in the inner surface 13b of the insertion piece 13. A lid for closing the end of the building louver 10 can be attached using the screw holes 16.

[0016] The second louver material 20 is a long metal material, for example, an extruded aluminum material. The second louver material 20 has the same shape over its entire length and has a cross-sectional shape as shown in FIG. 3. The second louver material 20 has a substantially U-shaped cross-section and includes a side wall part 21 and a mounting part 23.

[0017] The side wall portions 21 are formed so as to protrude forward from both end portions of the mounting portion 23, and are formed as a pair on the left and right. The interval between the pair of side wall portions 21 is set to a width that allows the pair of insertion pieces 13 of the first louver material 11 to be inserted. The pair of side wall portions 21 are configured to engage with the pair of insertion pieces 13 of the first louver material 11 on the inner surface 21b, and the outer surface 21a serves as a decorative surface. That is, the outer surface 21a in the longitudinal direction of the side wall portion 21 constitutes the decorative side surface 10b of the building louver 10. The outer surface 21a according to the present embodiment is a flat surface without unevenness.

[0018] An engaging portion 22 is formed near the tip inside the side wall portion 21. This engaging portion 22 is a portion for engaging with the first louver material 11, and is formed on the inner surface 21b of the side wall portion 21. The engaging portion 22 bulges inward more than the inner surface 21b of the side wall portion 21, and has a contact surface 22b parallel to the inner surface 21b. As shown in FIG. 4, this contact surface 22b contacts the engaging surface 14b of the first louver material 11 when the first louver material 11 and the second louver material 20 are combined. Further, a protrusion 22c protrudes from this contact surface 22b. When the first louver material 11 and the second louver material 20 are combined, the protrusion 22c enters the engaging groove 15 of the first louver material 11 and fits so that the first louver material 11 and the second louver material 20 do not easily fall off.

[0019] Further, the front end 22a of this engaging portion 22 (that is, the front end of the side wall portion 21) is an inclined surface inclined at about 45 degrees with respect to the outer surface 21a. In other words, this front end 22a is formed so as to form an acute angle of about 45 degrees with the outer surface 21a. The front end 22a of the engaging portion 22 contacts the abutting portion 12b when the first louver material 11 and the second louver material 20 are combined.

[0020] The attachment part 23 is a part that is directly fixed to the construction surface of the housing 50. Although not particularly shown, this attachment part 23 can be fixed to the construction surface with bolts or the like. Here, the construction surface may be substantially the surface of the housing 50, and it may be a wall surface or a ceiling surface. Also, a flat construction surface may be formed with a base material. Next, a procedure for constructing the building louver 10 by combining the above-described first louver material 11 and second louver material 20 will be described. First, the attachment part 23 is fixed to the construction surface of the housing 50. As a result, the second louver material 20 is fixed to the housing 50, and a state is obtained in which the pair of side wall parts 21 protrude forward.

[0021] Next, as shown in FIG. 3, the first louver material 11 is attached from the front. Specifically, the insertion piece 13 of the first louver material 11 is inserted between the side wall parts 21 of the second louver material 20. In the process of inserting the first louver material 11, the protrusion 22c hits the protrusion 14, but the first louver material 11 is press-fitted as it is. As a result, the protrusion 22c is guided by the guide surface 14c, and the insertion piece 13 and the side wall part 21 are elastically deformed so that the protrusion 22c gets over the protrusion 14.

[0022] When the first louver material 11 is inserted to the deepest part, as shown in FIG. 4, the protrusion 22c enters and fits into the engagement groove 15. As a result, the first louver material 11 is prevented from easily falling off from the second louver material 20. Also, since the engagement surface 14b and the contact surface 22b are in surface contact, the two are stably joined without rattling. Further, since the tip of the insertion piece 13 abuts on the inside of the attachment part 23, it is prevented that the insertion piece 13 enters deeper.

[0023] Note that the abutting part 12b and the front end 22a of the side wall part 21 are in contact with each other at an inclined surface. That is, the corner part 10c at the front end of the building louver 10 has a so-called "finished shape" in which the end surfaces formed at about 45 degrees are joined to each other. This is done in order to make the decorative front surface 10a and the decorative side surface 10b have different colors or patterns.

[0024] That is, as shown in FIG. 1, for the architectural louver 10 according to the present embodiment, the decorative front surface 10a and the decorative side surface 10b have different colors or patterns. Specifically, different decorative sheets 28 are attached to the decorative front surface 10a and the decorative side surface 10b.

[0025] Here, since the first louver material 11 of the architectural louver 10 according to the present embodiment has the decorative front surface 10a and the second louver material 20 has the decorative side surface 10b, it is easy to attach different decorative sheets 28 to the decorative front surface 10a and the decorative side surface 10b. And the corner portion 10c is formed in a stopping shape, that is, since the boundary between the first louver material 11 and the second louver material 20 is set at the corner portion 10c, the boundary between the two is less conspicuous. In other words, when looking at the decorative front surface 10a from the front, the second louver material 20 is difficult to see, and when looking at the decorative side surface 10b from the side, the first louver material 11 is difficult to see. In this way, by making the abutting portion 12b and the front end 22a of the side wall portion 21 abut against each other with an inclined surface, the decorative front surface 10a is composed only of the first louver material 11, and the decorative side surface 10b is composed only of the second louver material 20. Also, since the boundary between the two is less conspicuous, the design property when the decorative front surface 10a and the decorative side surface 10b have different colors or patterns can be enhanced.

[0026] In addition, in order to finish the boundary of the corner portion 10c neatly, the decorative sheet 28 may be attached by the method shown in FIG. 5. That is, when attaching the decorative sheet 28 to the first louver material 11, as shown in FIG. 5(a), the decorative sheet 28 may be attached so as to continuously cover the front surface 12a and the abutting portion 12b. Also, when attaching the decorative sheet 28 to the second louver material 20, as shown in FIG. 5(b), the decorative sheet 28 may be attached so as to continuously cover the outer surface 21a and the front end 22a. At this time, one decorative sheet 28 continuous with the two outer surfaces 21a may be attached, or different decorative sheets 28 may be used for each outer surface 21a. By attaching in this way, the decorative sheet 28 can be attached without unevenness at the boundary of the corner portion 10c.

[0027] In the above-described embodiment, the makeup sheet 28 is used to change the color and pattern of the makeup surface. However, the present invention is not limited to this, and the color and pattern of the makeup surface may be changed by anodizing or painting.

[0028] Also, in the above-described embodiment, the makeup front surface 10a and the makeup side surface 10b are formed as flat surfaces. However, the present invention is not limited to this, and they can have any shape. For example, the makeup front surface 10a and the makeup side surface 10b may be formed as concave-convex surfaces or curved surfaces.

[0029] As described above, according to the present embodiment, the front surface 12a of the first louver material 11 constitutes the makeup front surface 10a of the building louver 10, and the pair of side wall portions 21 (outer side surfaces 21a in the longitudinal direction) of the second louver material 20 constitute the makeup side surface 10b of the building louver 10. That is, the makeup front surface 10a and the makeup side surface 10b are configured by different members. According to such a configuration, before combining the first louver material 11 and the second louver material 20, the makeup sheet 28 can be separately attached to the makeup front surface 10a and the makeup side surface 10b, or anodizing or painting can be performed. Therefore, even when it is desired to make the respective makeup surfaces of the louver have different colors and patterns, the work can be easily and quickly performed without the need for special techniques or a great deal of labor.

[0030] In addition, since the building louver 10 is completed simply by combining the first louver material 11 and the second louver material 20, which have been separately colored or patterned, during construction (the two are fitted together simply by press-fitting the first louver material 11 into the second louver material 20 from the front), the assembly work is also easy.

[0031] In addition, the first louver material 11 is provided with an abutting portion 12b that abuts against the front ends 22a of the pair of side wall portions 21 of the second louver material 20, and the front ends 22a of the pair of side wall portions 21 and the abutting portion 12b are in contact with each other on an inclined surface. For this reason, the boundary between the two members comes to the tip of the corner portion 10c, and the boundary is not conspicuous. Further, since the decorative front surface 10a and the decorative side surface 10b are completely separate members, it is easy to perform surface finishing work or manufacture them in different colors. Further, even when anodizing or painting is performed, if they are separate members, there is no need for treatments such as curing the boundary, and the working cost is suppressed.

[0032] Moreover, it is also possible to use a decorative sheet 28 that continuously covers the front surface 12a and the abutting portion 12b of the first louver material 11. That is, the end portion of the decorative sheet 28 attached to the front surface 12a of the first louver material 11 can be folded back and attached to the back surface (abutting portion 12b). By using such a decorative sheet 28, the boundary of the corner portion 10c can be finished easily and evenly.

[0033] Moreover, it is also possible to use a decorative sheet 28 that continuously covers the outer surface 21a and the front end 22a of the side wall portion 21 of the second louver material 20. That is, the end portion of the decorative sheet 28 attached to the side wall portion 21 of the second louver material 20 can be folded back and attached to the front end 22a. By using such a decorative sheet 28, the boundary of the corner portion 10c can be finished easily and evenly.

[0034] Note that, by using a decorative sheet 28 that continuously covers the front surface 12a and the abutting portion 12b of the first louver material 11 and a decorative sheet 28 that continuously covers the outer surface 21a and the front end 22a of the side wall portion 21 of the second louver material 20, and making the end portions of these two decorative sheets 28 be sandwiched between the abutting portion 12b and the front end 22a and come into contact with each other, the boundary of the decorative sheet 28 can be hidden. Therefore, the architectural louver 10 made of two decorative sheets 28 with different colors or patterns can be finished more easily and evenly.

[0035] Further, the pair of side wall portions 21 of the second louver member 20 form the decorative side surface 10b on the outer side surface 21a, and an engaging portion 22 for engaging with the first louver member 11 is formed on the inner side surface 21b. According to such a configuration, even when the decorative front surface 10a and the decorative side surface 10b are configured by different members, by making full use of both sides of the side wall portion 21 without excess or deficiency, the building louver 10 can be manufactured with a small number of parts.

[0036] Also, the second louver member 20 is directly fixed to the construction surface of the housing 50. That is, the second louver member 20 also functions as a fixing means to the housing 50. According to such a configuration, the building louver 10 can be manufactured with a small number of parts. (Modification example) In the above-described embodiment, an example in which the second louver member 20 is directly fixed to the construction surface has been described, but the present invention is not limited to this.

[0037] For example, as shown in FIGS. 6 and 7, a receiving member 40 directly fixed to the construction surface of the housing 50 may be provided, and the second louver member 30 may be fixed to this receiving member 40. Since the basic aspects of the first louver member 11 and the second louver member 30 according to this modification example are the same as those of the above-described embodiment, only the parts that are significantly different from the above-described embodiment will be described below.

[0038] First, the second louver member 30 shown in this example does not include an attachment portion 23 for fixing to the housing 50. Instead, it includes a first intermediate wall 33, a second intermediate wall 34, a locking wall 35, and a locking portion 36.

[0039] The first intermediate wall 33 and the second intermediate wall 34 are walls formed inside the second louver member 30 and are installed between the pair of side wall portions 31. Among these, the first intermediate wall 33 formed at the front is formed such that the tip of the insertion piece 13 abuts when the first louver member 11 is attached. Thereby, when the first louver member 11 is attached, it is possible to prevent the insertion piece 13 from entering deeply.

[0040] The locking wall 35 is formed to protrude inward from the inner surface 31b of the second louver member 30. This locking wall 35 protrudes so as to face each other from the left and right inner surfaces 31b. This locking wall 35 is set so that the tip of the engaging piece 42, which will be described later, abuts when the second louver member 30 is attached to the receiving member 40.

[0041] The locking portion 36 is a part of the side wall portion 31 and is the rear end portion of the side wall portion 31. This locking portion 36 protrudes rearward of the locking wall 35. Further, a claw portion 37 is formed inside this locking portion 36. This claw portion 37 is for engaging with a check portion 43, which will be described later.

[0042] The receiving member 40 is a long member made of metal, for example, an extruded shape made of aluminum. This receiving member 40 has a substantially U-shaped cross section and includes a mounting piece 41 and an engaging piece 42.

[0043] The engaging piece 42 is formed to protrude forward and is formed as a pair on the left and right. This engaging piece 42 is a portion fixed inside a pair of side wall portions 31 (locking portions 36) of the second louver member 30. That is, this engaging piece 42 is inserted and fitted between a pair of side wall portions 31 (locking portions 36) from the rear of the second louver member 30. A check portion 43 is formed near the tip of this engaging piece 42. This check portion 43 is a portion for engaging with the second louver member 30. This check portion 43 is formed so as to engage with the claw portion 37 when the receiving member 40 and the second louver member 30 are combined. The mounting piece 41 is a portion directly fixed to the construction surface of the housing 50. Although not particularly shown, this mounting piece 41 can be fixed to the construction surface with bolts or the like. Next, the procedure for installing the above-described building louver 10 will be described. First, the receiving member 40 is fixed to the construction surface of the housing 50. That is, the mounting piece 41 is fixed to the housing 50. As a result, the engaging piece 42 protrudes forward.

[0044] Next, attach the second louver member 30 from the front. Specifically, insert the engaging piece 42 of the receiving member 40 between the side wall portions 31 (locking portions 36) of the second louver member 30. As the insertion progresses, the claw portion 37 and the check portion 43 interfere with each other, but the second louver member 30 is press-fitted as it is. As a result, the engaging piece 42 and the side wall portion 31 are elastically deformed, and the check portion 43 moves deeper (forward) than the claw portion 37. Thereby, the claw portion 37 and the check portion 43 engage with each other, and the tip of the engaging piece 42 abuts against the locking wall 35, so that the second louver member 30 is attached to the receiving member 40.

[0045] Finally, attach the first louver member 11 to the second louver member 30. This procedure is as already described with reference to FIGS. 3 and 4. That is, by replacing the engaging portion 22 shown in FIGS. 3 and 4 with the engaging portion 32 shown in FIGS. 6 and 7, the first louver member 11 can be attached to the second louver member 30 by the procedure already described in FIGS. 3 and 4.

[0046] In this way, by providing the receiving member 40 that is directly fixed to the construction surface and fixing the second louver member 30 to the receiving member 40, it is possible to cope with various protruding dimensions only by changing the second louver member 30. That is, by preparing only molds with different dimensions for the second louver member 30, various types of building louvers 10 can be provided, so that the manufacturing cost can be suppressed.
