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

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

The first louver member 11 is a long metal member, for example, an extruded aluminum member. This first louver material 11 has the same shape over its entire length, and is formed in the cross-sectional shape shown in FIG. The 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 extending rearward from both ends of the front piece 12.

A front surface 12a (surface) of the front piece 12 constitutes a decorative front surface 10a of the architectural louver 10. The front surface 12a according to this embodiment is a flat surface without unevenness. Further, both ends of the front piece 12 have a shape that projects slightly laterally, and an abutting portion 12b is formed on the rear surface of this projecting portion. This abutting portion 12b is a portion that comes into contact with a front end 22a of a side wall portion 21, which will be described later. The abutting portion 12b is an inclined surface inclined at approximately 45 degrees with respect to the front surface 12a, in other words, it is formed to form an acute angle of approximately 45 degrees with the front surface 12a.

The insertion piece 13 is a portion that is fixed inside a pair of side wall portions 21, which will be described later. The insertion pieces 13 are provided as a pair of left and right pieces, and protrude in a direction perpendicular to the front piece 12. This insertion piece 13 is formed so as to be continuous from the abutting portion 12b. The insertion piece 13 according to this embodiment is inserted from the front between the pair of side wall parts 21, and is engaged with and fixed to the second louver material 20.

A protrusion 14 extending in the longitudinal direction is formed on the outer surface 13a of the insertion piece 13. This protrusion 14 is for engaging an engaging portion 22, which will be described later. The protrusion 14 is formed to protrude laterally from the outer surface 13a of the insertion piece 13, and includes a vertical surface 14a, an engagement surface 14b, and a guide surface 14c. The vertical surface 14a is the front surface of the protrusion 14, and is perpendicular to the outer surface 13a. The engagement surface 14b is a surface continuous from the end of the vertical surface 14a, and is parallel to the outer surface 13a. The guide surface 14c is a surface continuous from the end of the engagement surface 14b, and is an inclined surface connecting the end of the engagement surface 14b and the outer surface 13a. Note that an engagement groove 15 is recessed in the front side of the protrusion 14 and is sandwiched between the vertical surface 14a and the abutting portion 12b. This engagement groove 15 is a recess into which a projection 22c, which will be described later, is fitted. By fitting the protrusion 22c into the engagement groove 15, the side wall portion 21 and the insertion piece 13 are fixed so as not to fall off. Further, a screw hole 16 is formed in the inner surface 13b of the insertion piece 13. This screw hole 16 can be used to attach a lid that closes the edge of the architectural louver 10.

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

The side wall portions 21 are formed to protrude forward from both ends of the attachment portion 23, and are formed in a pair on the left and right. The distance 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 walls 21 are configured such that their inner surfaces 21b engage with the pair of insertion pieces 13 of the first louver material 11, and their outer surfaces 21a serve as decorative surfaces. That is, the outer surface 21a of the side wall portion 21 in the longitudinal direction constitutes the decorative side surface 10b of the architectural louver 10. The outer surface 21a according to this embodiment is a flat surface without unevenness.

An engaging portion 22 is formed near the inner tip of the side wall portion 21 . The 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 from the inner surface 21b of the side wall portion 21 and includes an abutting surface 22b parallel to the inner surface 21b. As shown in FIG. 4, this contact surface 22b contacts the engagement surface 14b of the first louver material 11 when the first louver material 11 and the second louver material 20 are combined. Furthermore, a protrusion 22c is formed to protrude from this contact surface 22b. When the first louver material 11 and the second louver material 20 are combined, this protrusion 22c enters into the engagement groove 15 of the first louver material 11, and the first louver material 11 and the second louver material 20 are easily connected. Fit so that it does not fall off.

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

The attachment portion 23 is a portion that is directly fixed to the construction surface of the frame 50. Although not particularly illustrated, this attachment portion 23 can be fixed to the construction surface with bolts or the like. Note that the construction surface here may be substantially the surface of the frame 50, and may be a wall surface or a ceiling surface. Alternatively, a flat construction surface may be formed using a base material.
Next, a procedure for constructing the architectural louver 10 by combining the first louver material 11 and the second louver material 20 described above will be described.
First, the attachment part 23 is fixed to the construction surface of the frame 50. As a result, the second louver material 20 is fixed to the frame 50, and the pair of side wall portions 21 protrude forward.

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 portions 21 of the second louver material 20. Although the protrusion 22c hits the protrusion 14 during the process of inserting the first louver material 11, the first louver material 11 is press-fitted as is. Thereby, the protrusion 22c is guided by the guide surface 14c, and the insertion piece 13 and the side wall portion 21 are elastically deformed, so that the protrusion 22c rides over the protrusion 14.

When the first louver material 11 is inserted all the way, the protrusion 22c enters and fits into the engagement groove 15, as shown in FIG. This prevents the first louver material 11 from easily falling off from the second louver material 20. Moreover, since the engaging surface 14b and the abutting surface 22b are in surface contact, they are stably coupled without wobbling. In addition, since the tip of the insertion piece 13 is in contact with the inside of the mounting portion 23, the insertion piece 13 is prevented from going deep inside.

Note that the abutment portion 12b and the front end 22a of the side wall portion 21 are in contact with each other on an inclined surface. That is, the corner portion 10c at the front end of the architectural louver 10 has a so-called "toe shape" in which the tip surfaces formed at approximately 45 degrees are joined to each other. The reason for doing this is to make the decorative front side 10a and the decorative side surface 10b different colors or patterns.

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

Here, in the architectural louver 10 according to the present embodiment, the first louver material 11 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 two. Since the corner portion 10c is shaped like a toe, that is, the boundary between the first louver material 11 and the second louver material 20 is set at the corner portion 10c, so that the boundary between the two is less noticeable. In other words, when the decorative front surface 10a is viewed from the front, the second louver material 20 is difficult to see, and when the decorative side surface 10b is viewed from the side, the first louver material 11 is difficult to see. In this way, by bringing the abutting portion 12b and the front end 22a of the side wall portion 21 into contact with each other on the inclined surface, the decorative front surface 10a is composed of only the first louver material 11, and the decorative side surface 10b is composed of only the second louver material 20. It is made up of. Furthermore, since the boundary between the two is less noticeable, the design can be improved when the decorative front surface 10a and the decorative side surface 10b are made in different colors or patterns.

Incidentally, in order to neatly finish the border of the corner portion 10c, a decorative sheet 28 may be attached by a method as shown in FIG. That is, when attaching the decorative sheet 28 to the first louver material 11, as shown in FIG. good. Further, when attaching the decorative sheet 28 to the second louver material 20, the decorative sheet 28 may be attached so as to continuously cover the outer surface 21a and the front end 22a, as shown in FIG. 5(b). . At this time, one continuous decorative sheet 28 may be attached to the two outer surfaces 21a, or a different decorative sheet 28 may be used for each outer surface 21a. By pasting in this manner, the decorative sheet 28 can be pasted without unevenness at the border at the corner 10c.

In the embodiment described above, the decorative sheet 28 is used to change the color and pattern of the decorative surface, but the present invention is not limited to this, and the color and pattern of the decorative surface can be changed by anodizing, painting, etc. You can change it.

Further, in the embodiment described above, the decorative front surface 10a and the decorative side surface 10b are formed as flat surfaces, but they are not limited to this and may have any shape. For example, the decorative front surface 10a and the decorative side surface 10b may be formed with an uneven surface or a curved surface.

As explained above, according to the present embodiment, the front surface 12a of the first louver material 11 constitutes the decorative front surface 10a of the architectural louver 10, and the pair of side wall portions 21 (longitudinal direction) of the second louver material 20 The outer surface 21a) constitutes the decorative side surface 10b of the architectural louver 10. That is, the decorative front surface 10a and the decorative side surface 10b are constructed from different members. According to such a configuration, before combining the first louver material 11 and the second louver material 20, the decorative sheet 28 is pasted or the anodic oxide film is applied to the decorative front surface 10a and the decorative side surface 10b separately. It can be treated and painted. Therefore, even if it is desired to give each decorative surface of the louver a different color or pattern, the work can be done easily and in a short time without requiring any special techniques or great effort.

In addition, the architectural louver 10 is completed by simply combining the first louver material 11 and the second louver material 20, which have been separately colored and patterned in this way, at the time of construction (the first louver material 11 is combined with the second louver material 20). The assembly work is also easy, as the two fit together simply by press-fitting from the front.

Further, the first louver material 11 includes an abutment portion 12b that abuts the front ends 22a of the pair of side walls 21 of the second louver material 20, and the front ends 22a of the pair of side walls 21 and the abutment portions 12b are inclined. It is in contact with the surface. Therefore, the boundary between the two members is located at the tip of the corner 10c, making the boundary less noticeable. Furthermore, since the decorative front side 10a and the decorative side surface 10b are completely separate members, it is easy to perform surface finishing work and manufacture them in different colors. Furthermore, even when anodizing or painting is performed, if the parts are separate members, there is no need to perform treatments such as curing the boundaries, which reduces work costs.

Further, a decorative sheet 28 that continuously covers the front surface 12a and the abutting portion 12b of the first louver material 11 can also be used. That is, the end portion of the decorative sheet 28 pasted on the front surface 12a of the first louver material 11 can be folded back and pasted to the back surface (abutting portion 12b). If such a decorative sheet 28 is used, the border of the corner 10c can be easily and evenly finished.

Further, 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 can also be used. That is, the end portion of the decorative sheet 28 pasted on the side wall portion 21 of the second louver material 20 can be folded back and pasted up to the front end 22a. If such a decorative sheet 28 is used, the border of the corner 10c can be easily and evenly finished.

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 that continuously covers the outer surface 21a and the front end 22a of the side wall portion 21 of the second louver material 20. 28, and if the ends of these two decorative sheets 28 are sandwiched and abutted by the abutment part 12b and the front end 22a, the boundary between the decorative sheets 28 can be hidden, so the two decorative sheets 28 can be Architectural louvers 10 with different colors and patterns can be finished more easily and evenly with decorative sheets 28.

Further, the pair of side wall portions 21 of the second louver material 20 have an outer surface 21a forming a decorative surface 10b, and an inner surface 21b having an engaging portion 22 for engaging with the first louver material 11. . According to such a configuration, even if the decorative front surface 10a and the decorative side surface 10b are made of different materials, both sides of the side wall portion 21 can be used in just the right amount, so that the architectural louver 10 can be constructed with a small number of parts. can be manufactured.

Further, the second louver material 20 is directly fixed to the construction surface of the frame 50. That is, the second louver material 20 also functions as a means for fixing to the frame 50. According to such a configuration, the architectural louver 10 can be manufactured with a small number of parts.
(Modified example)
In the above-described embodiment, an example in which the second louver material 20 is directly fixed to the construction surface has been described, but the present invention is not limited to this.

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

First, the second louver material 30 shown in this example does not have the attachment part 23 for fixing to the frame 50, but instead has a first intermediate wall 33, a second intermediate wall 34, a locking wall 35, and a locking wall 35. A stop portion 36 is provided.

The first intermediate wall 33 and the second intermediate wall 34 are walls formed inside the second louver material 30 and are constructed between the pair of side wall portions 31 . Among these, the first intermediate wall 33 formed at the front is formed so that the tip of the insertion piece 13 comes into contact with it when the first louver material 11 is attached. This prevents the insertion piece 13 from going deep when the first louver material 11 is attached.

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

The locking portion 36 is a part of the side wall portion 31 and is a rear end portion of the side wall portion 31. This locking portion 36 projects further rearward than the locking wall 35 . Furthermore, a claw portion 37 is formed inside the locking portion 36 . This claw portion 37 is for engaging with a check portion 43, which will be described later.

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

The engagement pieces 42 are formed to protrude forward, and are formed in pairs on the left and right sides. This engagement piece 42 is a portion that is fixed inside the pair of side wall portions 31 (locking portions 36) of the second louver member 30. That is, the engagement piece 42 is inserted from the rear of the second louver member 30 between the pair of side wall portions 31 (locking portions 36) and fitted therein. A check portion 43 is formed near the tip of this engagement piece 42 . This check portion 43 is a portion for engaging with the second louver material 30. This check portion 43 is formed to engage with the claw portion 37 when the receiving member 40 and the second louver material 30 are combined.
The attachment piece 41 is a part that is directly fixed to the construction surface of the frame 50. Although not particularly illustrated, this mounting piece 41 can be fixed to the construction surface with bolts or the like.
Next, a procedure for constructing the above-mentioned architectural louver 10 will be explained.
First, the receiving member 40 is fixed to the construction surface of the frame 50. That is, the mounting piece 41 is fixed to the frame 50. This causes the engagement piece 42 to protrude forward.

Next, the second louver material 30 is attached from the front. Specifically, the engaging piece 42 of the receiving member 40 is inserted between the side wall portion 31 (locking portion 36) of the second louver member 30. As it is inserted, the claw part 37 and the check part 43 interfere with each other, but the second louver material 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 further back (forward) than the claw portion 37 . As a result, the claw portion 37 and the check portion 43 engage with each other, and the tip of the engagement piece 42 abuts against the locking wall 35, thereby attaching the second louver member 30 to the receiving member 40.

Finally, the first louver material 11 is attached to the second louver material 30. This procedure has already been described with reference to FIGS. 3 and 4. That is, by replacing the engaging part 22 shown in FIGS. 3 and 4 with the engaging part 32 shown in FIGS. 6 and 7, the second louver material 30 can be replaced by the engaging part 32 shown in FIGS. The first louver material 11 can be attached.

In this way, if the receiving member 40 is directly fixed to the construction surface and the second louver material 30 is fixed to the receiving member 40, various protrusion dimensions can be obtained by simply changing the second louver material 30. can be accommodated. That is, by simply preparing molds with different dimensions for the second louver material 30, various types of architectural louvers 10 can be provided, so manufacturing costs can be suppressed.
