Description

  The present invention provides a grid-like shape for metal fittings that are pre-constructed around the outer stairs of the building, outer walls, rooftop towers, air conditioners, etc. The present invention relates to an improvement of a mounting bracket for mounting a louver for assembling.

  Metal louvers attached in a lattice pattern around the outer stairs, rooftop tower, and air-conditioning equipment around the building are formed by extruding a metal material such as aluminum alloy, for example, as shown in FIG. As shown in FIG. 2, it is formed in a long louver a that is continuous in the longitudinal direction, and this is attached to a mounting material b that is pre-constructed and attached to the outer surface or around the building / facility. Mounting comprising a square plate-like seat plate 30, a fastening bolt 32 fitted into a bolt insertion port 31 formed in the seat plate 30, and a fastening nut 33 screwed into the fastening bolt 32 and fastened. By assembling with the metal fitting c, it is used to be attached to a building or facility.

  The metal louver a is formed into a hollow cylindrical shape having a constant cross-sectional shape and continuous in the longitudinal direction by extrusion molding of a metal material such as an aluminum alloy. In FIG. 2, a cleavage opening 10 that is continuous in the longitudinal direction is formed in the upper and lower intermediate portions, and the attachment material b is attached to the attachment bracket c using the opening 10. Assembled into.

  The attachment material b for assembling the louver a is usually formed in an L-shaped cross-sectional shape and has an angle shape continuous in the longitudinal direction, and one side edge thereof is joined to the rear end face of the louver a. It arrange | positions so that it may become the attachment board part 20 of a, and it has installed in the predetermined position of a construction site as shown in FIG. As shown in FIG. 1, a bolt insertion hole 21 is provided for fitting the fastening bolt 32 of the mounting bracket c.

  As shown in FIG. 3, the mounting bracket c for mounting the louver a to the mounting material b usually has an upper and lower height dimension H formed from a metal plate such as a stainless steel plate. The width D in the left-right direction is larger than the upper and lower opening widths K of the cleaved opening 10 formed on the rear end surface, and the inner and lower dimensions on the rear end side where the opening 10 of the louver a is formed. A seat plate 30 formed in a shape that is substantially rectangular or rectangular horizontally long in the rear view, which has a dimension that substantially corresponds to the height h, and a head 320 that is inserted through a bolt insertion port 31 provided at a central portion thereof. And a fastening nut 33 that is screwed into a screw portion 321 of the fastening bolt 32.

  The assembly of the louver a to the mounting material b using the mounting bracket c is performed by inserting the square seat plate 30 of the mounting bracket c into the louver a and joining the inner surface of the rear wall 11 of the louver a. The screw portion 321 of the fastening bolt 32 with the head 320 that is inserted in advance in the seat plate 30 is protruded rearward from the opening 10 formed in the rear wall 11 of the louver a, The screw portion 321 is passed through a bolt insertion hole 21 formed in the attachment plate portion 20 of the attachment material b and protrudes to the rear surface side of the attachment plate portion 20, and a tightening nut 33 is screwed into the screw portion 321. By tightening together, as shown in FIG. 3, the rear walls 11 and 11 of the louver a located above and below the opening 10 are sandwiched and fixed between the seat plate 30 and the mounting plate portion 20 of the mounting material b. It is done by putting it on.

  As shown in FIG. 5, the seat plate 30 has a vertical height dimension H that is narrower than the opening width of the opening 10 for mounting the rear end of the louver a, and a horizontal width dimension D, It is formed in the shape of a narrow strip plate having a size substantially corresponding to the vertical height of the lumen at the rear end of the louver a, and the narrow strip-shaped seat plate 30 is formed in a horizontally long posture from the opening 10. It is inserted into the louver a, and when it is inserted, it is converted into a vertically long posture that crosses the opening 10 by the rotation of the tightening bolt 32 that has been inserted, and the tightening by the tightening bolt 32 is performed. There is a form. In this configuration, the seat plate 30 is narrow, so that sufficient strength cannot be obtained during tightening, and vibration caused by wind that the louver a assembled by tightening or tightening causes during use. As a result, when the seat plate 30 is rotated with respect to the louver a, the seat 30 protrudes from the opening 10 and causes a problem that the assembly of the louver a is uncertain. Therefore, the seat plate 30 is usually formed in a square plate shape that is wider than the opening width of the opening 10.

  Insertion of the mounting bracket c formed in the shape of a rectangular plate wider than the opening width of the opening 10 into the louver a of the seat plate 30 is performed by the tightening bolt 32 with respect to the bolt insertion port 31 of the seat plate 30. When only the seat plate 30 is inserted into the lumen of the louver a, it is difficult to insert the tightening bolt 32 from the front side of the seat plate 30. The fastening bolt 32 is inserted through the insertion port 31, and the seat plate 30 in this state is fitted into the longitudinal end of the louver a with the seat plate 30 and the head 320 of the fastening bolt 32. This is done by inserting the

  This is because the insertion of the seat plate 30 with the tightening bolts 32 inserted into the louver a is inclined as shown in FIG. 6 so that the rear surface side of the louver a is cleaved. If the screw part 321 of the fastening bolt 32 inserted through the seat plate 30 and the seat plate 30 interfere with the upper and lower mouth edges of the opening port 10, the insertion cannot be performed. For this reason, it is because the insertion of the seat plate 30 through which the tightening bolt 32 is inserted into the louver a is performed from the edge of the louver a.

  The louver a is usually made into a long object of about 1.8 to 2.7 m, and a large number of attachment materials b for assembling and fixing the louver a with the attachment bracket c are provided on the construction site at intervals of 50 to 60 cm. Installed in parallel. The lateral length of the construction site, such as the outer stairs outer periphery, rooftop tower, and air conditioning equipment, of the building that louver a is attached to the mounting material b and is hidden, is usually less than the length of one louver a. It is very long and a plurality of louvers a are assembled and assembled.

  Therefore, when the louver a is mounted on the mounting member b in parallel with the mounting plate c including the seat plate 30, the fastening bolt 32, and the fastening nut 33, the louver a is inserted from one edge of the louver a. When the mounting bracket c is first assembled to the mounting material b close to the edge, the mounting bracket c to be inserted next from the edge cannot be slid to a position corresponding to the next mounting material b. The seat plate 30 of the mounting bracket c to be inserted into the louver a from the edge of the louver a is positioned at a position corresponding to each of the mounting materials b arranged in parallel before the mounting plate c of the louver a is assembled to the mounting material b. Everything must be coordinated. In addition, the seat plate 30 through which the fastening bolts 32 of the mounting bracket c prepared in the louver a corresponding to each mounting material b is moved from the position corresponding to the mounting material b in the louver a. It must be moved to return to the position corresponding to the mounting material b to be assembled, and the mounting material b to be assembled must be correctly selected and assembled. If the mounting material b to be assembled is wrong, the seat plate 30 of the mounting bracket c that has become idle due to that cannot be moved to a position corresponding to another mounting material b by jumping over the assembled mounting bracket c. This is because the assembled mounting bracket c must be unwound and redone. For this reason, the assembly of the louver a to the mounting material b using the mounting bracket c has a problem that makes the operation troublesome.

  The problem to be solved in the present invention is to use a mounting bracket c comprising a seat plate 30 to be inserted into the louver a, a tightening bolt 32 to be inserted therethrough, and a tightening nut 33 to be screwed thereto. Thus, an object of the present invention is to provide means for solving troublesome problems that have occurred when the louver a is assembled to the mounting material b that is erected on the construction site.

  The means of the present invention for solving the above-described problems has been made on the basis of knowledge obtained through various trials and errors.

  In order to prevent the seat plate 30 of the mounting bracket c from escaping from the opening 10 on the rear surface of the louver a when the fastening plate 32 is tightened, the height dimension in the vertical direction is set on the rear wall 11 of the louver a. It must be formed larger than the dimension of the opening width in the vertical direction of the formed opening 10, but the front and rear thickness dimensions should be strong enough when tightening with the tightening bolt 32. It is sufficient that the thickness of the normal seat plate is smaller than the size of the opening width above and below the opening 10.

  The seat plate 30 formed in this manner has a louver a as a slanted posture as long as the fastening bolt 32 inserted through the seat plate 30 does not interfere with and support the upper and lower edges of the opening 10 at the rear end of the louver a. The louver a from the opening 10 is inserted through the opening 10 at the rear end, passed through the opening 10 and inserted into the louver a, and then the seat plate 30 is returned to the upright position. Insertion into is possible.

  When the seat plate 30 is inclined, the fastening bolt 32 is supported on the edge of the opening 10. The fastening bolt 32 inserted through the seat plate 30 is attached to the seat plate 30. If tilting in the vertical direction is made free, when the seat plate 30 is placed in an oblique posture and inserted into the louver a from the opening 10, the fastening bolt 32 is attached to the rear surface of the seat plate 30. Is rotated with respect to the seat plate 30 such that the fastening bolt 32 is supported on the edge of the opening 10, and the seat plate 30 is moved from the opening 10 into the louver a. The knowledge that it can be inserted is obtained, and in order to make the fastening bolt 32 rotatable relative to the seat plate 30 in this way, the bolt insertion port of the fastening bolt 32 and the seat plate 30 is provided. The fitting part with 31 is configured as a ball joint. There are various means such as, but the rotation of the fastening bolt 32 with respect to the seat plate 30 may be only the vertical rotation. To obtain this rotation, the bolt insertion port 31 is This is because the knowledge that it is sufficient to form a long hole in the vertical direction is sufficient.

Therefore, in the present invention, as a means for solving the above-described problems, a square plate-like seat plate 30 and a fastening with a head portion 320 fitted into a bolt insertion port 31 provided in the seat plate 30 are provided. A bolt insertion port 31 formed in the seat plate 30 is attached to the mounting plate c for mounting a louver comprising a mounting bolt 32 and a tightening nut 33 screwed into a screw portion 321 of the tightening bolt 32. A mounting bracket for mounting a louver is provided, which is formed in the shape of a long long hole in the vertical direction that allows the tilting bolt 32 inserted into the insertion port 31 to be tilted in the vertical direction with respect to the seat plate 30.
At the same time, the bolt insertion port 31 for inserting the fastening bolt 32 formed on the seat plate 30 has a small vertical dimension at a portion close to the front surface side of the seat plate 30 and approaches the rear surface side of the seat plate 30. In the longitudinal side view in which the vertical dimension increases, a mounting bracket for mounting a louver is provided, which is formed in a vertically elongated slot having a lateral cone shape.
Furthermore, in order to make the tilting bolt 32 tilt and rotate smoothly with respect to the seat plate 30 in a state where the rear surface side of the head 320 is in contact with the front surface side of the seat plate 30, Providing means for forming the inner side of the part 320 facing the front surface of the seat plate 30 in an arcuate protrusion T in a side view,
Furthermore, in a front view side of the seat plate 30, in a side view that fits with an arc-shaped protrusion T formed inside the head 320 of the tightening bolt 32 at a peripheral portion of the inlet portion of the bolt insertion port 31. Proposed means to form the concave groove w,
Further, on the rear surface side of the head portion 320 of the tightening bolt 32, a convex shape is formed in a side view that fits into a concave groove w in a side view provided on the front surface side of the seat plate 30 in the peripheral portion of the bolt insertion port 31. A means for forming the protruding portion T is proposed.

  The mounting bracket for louver attachment according to the present invention means that the fastening bolt 32 fitted into the bolt insertion port 31 of the seat plate 30 is formed into a long hole shape in the vertical direction of the bolt insertion port 31. Since the seat plate 30 is inserted into the louver a with the fastening bolt 32 inserted therethrough, the fastening bolt 32 is inserted into the seat plate 30. In this state, the seat plate 30 is inserted through the opening 10 so that the seat plate 30 is slanted with respect to the opening 10 on the rear surface of the louver a. By going, it can be inserted into the louver a.

  As a result, the seat plate 30 of the mounting bracket c is in the longitudinal direction of the opening 10 on the rear surface of the louver a without being restricted by the mounting bracket c already inserted and assembled, with the fastening bolt 32 inserted. Since it can be inserted into the louver a at any time from a desired place in the above, various problems that have occurred in the mounting operation of the louver a by the mounting bracket c can be solved.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  7 to 19 show a first embodiment of a mounting bracket for mounting a louver according to the present invention.

FIG. 13 is a side view of a fastening bolt and a fastening nut of the same mounting bracket, FIG. 14 is a front view of the fastening bolt and the fastening nut, and FIG. 15 is a fastening bolt of the same. FIG. 16 is a rear view of a state in which a seat plate into which a tightening bolt is inserted is inserted into the rear end of the louver, and FIG. 16 is a direction in which the same seat plate is screwed. FIG. 18 is an explanatory diagram of a state in which the tightening bolt is rotated upward with respect to the seat plate. FIG. 19 is an explanatory view of the state in which the tightening bolt is rotated downward with respect to the seat plate. In these drawings, a is a louver, b is a mounting material, c is a mounting bracket, and 30 is a seat plate of the mounting bracket c. , 31 is a bolt insertion port provided in the seat plate 30, 32 is a fastening bolt, and 33 is a fastening nut.

  The louver a is a normal metal louver formed by extrusion processing from a metal material such as an aluminum alloy. The louver a shown in this embodiment is a louver body 1 of a normal metal louver. It is in the form formed in a cylindrical square shape, and is usually marketed as having a front and rear width of 120 mm and a top and bottom thickness of 40 mm. The opened opening 10 for attachment is formed in an opening width of 20 mm.

  The mounting material b is made of a normal angle steel formed by bending from a metal plate such as a steel plate and is erected in a predetermined place at a construction site with a predetermined length. is there.

  The mounting bracket c includes a seat plate 30, a fastening bolt 32 with a head 320 that is fitted into a bolt insertion port 31 that is opened to the seat plate 30, a fastening nut 33 that is screwed into the fastening bolt 32 and fastened. Although the mounting bracket c in this example is formed for mounting the cylindrical / square louver a made in the above-described dimensions and shape, in rear view, The vertical width is 25 mm, which is wider than the opening width of the opening 10 on the rear surface of the louver a, and the horizontal width is from the bottom surface to the ceiling surface inside the rear end of the louver a. The front and rear thicknesses are 37 mm corresponding to the height dimension of 12.5 mm, which is larger than one half of the opening width of the opening 10 described above, and is 12.5 mm. When the seat plate 30 is used for attaching a louver in which the opening width of the opening 10 formed on the rear end face is set to 12 mm, the vertical width is 16 mm. Will be changed.

  And this seat plate 30 is formed in a laterally long rhombus on the left and right sides, with the cutting lines parallel to each other with the cutting lines parallel to the bottom side at an angle of about 45 degrees with respect to the bottom in the rear view. The dimension between the hypotenuse and the hypotenuse which is the horizontal width dimension on the left and right is 37 mm corresponding to the internal dimension between the ceiling surface and the bottom surface of the louver a.

  The inclination direction of the side edges forming the left and right hypotenuses with the seat plate 30 as a rhombus is set so that the left and right hypotenuses incline to the right as shown in FIG. When the seat plate 30 is inserted into the louver a as shown in FIG. 16, the seat plate 30 is rotated in the direction of screw tightening the fastening bolt 32 fitted to the seat plate 30. Further, the left and right oblique sides of the seat plate 30 that rotates following this contact with the ceiling surface and the bottom surface inside the louver a, thereby preventing the seat plate 30 from rotating thereafter and being integrated with the louver a. It is trying to be in a state of being connected to.

  The square plate-shaped seat plate 30 is formed in a horizontally long rhombus that is a slanted side with its right and left sides inclined, and a tightening bolt 32 with the seat plate 30 inserted therein is tightened with a screw. By rotating the seat plate 30 in the above-mentioned direction by rotating in the direction, the opposing distance is substantially corresponding to the height dimension from the ceiling surface to the bottom surface of the lumen of the rear end portion of the louver a. The sides are brought into contact with the ceiling surface and the bottom surface in the louver a, respectively, thereby reducing the rotational angle amount of the seat plate 30 when the seat plate 30 is fixed in the louver a, When the fixed state is obtained quickly, and the seat plate 30 is rotated so that the left and right sides of the seat plate 30 are in contact with the ceiling surface and the bottom surface of the louver a, respectively. Conventionally, in order to make the pivoting operation of the seat plate 30 smooth, it is shown in FIGS. The corners of the side and upper sides of the seat plate 30 are cut obliquely or chamfered in an arc shape, and the rear walls 11 and 11 of the rear end portion of the louver a are generated. The purpose of this is to make the fastening and fixing firmly without reducing the area of the contact portion of the seat plate 30 in contact with the front surface. It is possible to chamfer the corner portion of the seat plate 30 formed into the rhombus to such an extent that the area of the contact portion is not reduced.

  Rotation of the seat plate 30 to bring the left and right sides of the seat plate 30 into contact with the ceiling surface and the bottom surface in the louver a is as in the conventional example shown in FIGS. Even if the corner part of the side and the upper side is obliquely or arcuately chamfered on the seat plate 30, it must be rotated approximately 90 degrees until the left and right sides are in a horizontal orientation. However, in the seat plate of the embodiment of the present invention means in which the left and right sides are inclined, the seat plate has already been rotated by the inclination angle of the inclined side. In other words, if the seat plate 30 is rotated by the remaining angle obtained by subtracting the inclination angle of the side that is the hypotenuse from 90 degrees, the side is brought into contact with the ceiling surface / bottom surface in parallel, and the louver a Therefore, the rotational angle of the seat plate is reduced and the seat plate 30 is fixed in the louver a. To speed up the rotation operation of up to.

  In the seat plate 30, the left and right width dimensions are formed so as to substantially correspond to the height dimension from the bottom surface of the lumen at the rear end of the louver a to the ceiling surface, and inserted into the louver a. By rotating, the left and right sides are brought into contact with the ceiling surface and the bottom surface of the lumen of the louver a with the upper and lower sides as the upper and lower sides. In this state, the upper and lower rear walls 11 and 11 at the rear end of the louver a. The part that abuts the front surface is made to function as a fastening surface.

  As shown in FIG. 3, the seat plate in the conventional mounting bracket is designed so that the rotation operation when the seat plate is rotated by 90 degrees is performed without causing the grip. On the other hand, since the portion of the side that is to be supported is cut in advance from the center line in the rotational direction, the area of the portion that functions as a tightening surface is narrowed. In the seat plate 30 of this embodiment, the left and right sides which become the upper side and the lower side by rotation are formed on the hypotenuse inclined in the rotation direction, and the hypotenuse is the angle obtained by subtracting the inclination angle from 90 degrees. When the seat plate 30 is rotated together with the seat plate 30, the left and right side edges are in direct contact with the ceiling surface and the bottom surface of the louver a. Excised obliquely Even if there is a minute, an inclination angle is added on the other side, and the area of the contact portion of the left and right side abutting on the front side of the rear walls 11 and 11 of the rear end portion of the louver a There is no reduction, and therefore tightening and fixing are made strong.

  By the way, the upper and lower end faces of this seat plate 30 are formed on the arc surface as shown in FIG. 10 from the front edge to the rear edge thereof, and thereby the fastening bolt 32 is inserted. When the seat plate 30 in the state is laid back and forth, the upper and lower end surfaces of the seat plate 30 are the upper and lower rims of the open port 10 when the seat plate 30 is inserted into the louver a from the open port 10 on the rear surface of the louver a. We try to avoid contact and interference. Furthermore, the arc surface formed on the upper and lower end surfaces of the seat plate 30 is formed in a shape that narrows the distance between the upper and lower arc surfaces toward the front, and thereby the seat plate 30 is formed on the louver a. The operation / work when the rear opening 10 is inserted into the louver a can be performed more easily.

  Further, on the front side of the seat plate 30 of this embodiment, a concave groove w that swells in an arc shape toward the rear side is formed in the upper and lower intermediate portions so as to be continuous in the left-right direction. The arc-shaped concave groove w is formed so that the fastening bolt 32 fitted into the bolt insertion port 31 of the seat plate 30 is in the state where the rear surface side of the head 320 is in contact with the front surface side of the seat plate 30. This is for smooth rotation operation when tilting and rotating in the vertical direction with respect to 30, and the rear surface side of the head 320 of the tightening bolt 32 at the center portion on the left and right of the front surface side of the seat plate 30 abuts. However, in this example, in order to facilitate the formation of the concave groove w with respect to the portion of the seat plate 30, the left and right ends of the seat plate 30 may be formed. It is formed as a concave groove w that continues from the end to the other end. For this reason, the part of this concave groove w that deviates left and right from the part facing the rear surface side of the head 320 of the tightening bolt 32 is a part of play having no special function.

  A bolt insertion port 31 formed as an insertion port for the fastening bolt 32 in the seat plate 30 is a long hole extending in the vertical direction with a width corresponding to the outer diameter of the fastening bolt 32. In this example, As shown in FIG. 12, in the side view close to the front side of the seat plate 30, the vertical length is narrow, and as the side plate approaches the rear side, the vertical length increases in a side view. As shown in FIGS. 18 and 19, the upward and downward rotation of the tightening bolt 32 causes the downward rotation of the tightening bolt 32 to be an elongated hole. This is performed without creating a space for play inside the bolt insertion port 31.

  As shown in FIGS. 13 to 15, the fastening bolt 32 to be inserted into the bolt insertion port 31 of the seat plate 30 is formed with the rear side of the head 320 on the front side of the seat plate 30. It is formed in a shape that forms a long block shape on the left and right formed on the protruding portion T of the convex arc surface corresponding to the bottom surface of the arc-shaped concave groove w, thereby forming a T-shape as a whole.

  20 to 25 show another embodiment. In this example, the means of the present invention for a mounting bracket for mounting a louver is applied to a mounting bracket in a mode in which a seat plate is a square plate member.

  The mounting bracket for mounting the louver in this example is fitted into a seat plate 30 formed from a plate material made of a metal material such as stainless steel in a square shape, and a bolt insertion opening 31 opened at the central portion of the seat plate 30. It comprises a fastening bolt 32 with a head 320 to be inserted, and a fastening nut 33 that is screwed into and fastened to a screw portion 321 of the fastening bolt 32, and is formed on the square seat plate 30. The bolt insertion port 31 is configured in the shape of an elongated hole in the vertical direction in which the fastening bolt 32 inserted through the bolt insertion port 31 can be tilted and rotated up and down with respect to the seat plate 30. .

  The seat plate 30 is a plate-like seat plate formed from a metal plate such as stainless steel by forming a rhombus having left and right sides as oblique sides, and the inclination direction of the left and right sides as the oblique sides thereof is The fastening bolt 32 inserted into the seat plate 30 is set so as to incline in the screwing direction, and the inclination angle is about 45 degrees.

  As shown in FIG. 20, the rhombus-shaped seat plate 30 has a vertical dimension of 40 mm, an opening 10 having an opening width of 20 mm, and an inner ceiling surface to a bottom surface of 37 mm. The thickness is 10 mm, the vertical width is 25 mm wider than the opening width of the opening 10 of the louver a, and the left and right width dimensions are the ceiling height inside the louver a. It is formed in a substantially corresponding 37 mm shape.

  As shown in FIG. 21, the bolt insertion port 31 for inserting the fastening bolt 32 opened in the seat plate 30 is an intersection of two virtual diagonal lines connecting two pairs of diagonals in the rear view of the seat plate 30. The center point is located at the position, and it is formed in the shape of an elongated hole having a width corresponding to the outer diameter of the screw portion 321 of the tightening bolt 32. Then, as shown in FIG. 20, the elongated hole-shaped bolt insertion port 31 has a small vertical diameter at a portion close to the front surface side of the seat plate 30 and is gradually moved upward and downward toward a portion close to the rear surface side. It is formed in a shape that forms a lateral cone in a longitudinal side view with a large aperture.

  The bolt insertion port 31 is formed in the shape of a long hole in the vertical direction. The clamping bolt 32 inserted into the bolt insertion port 31 is held in the vertical direction by holding the screw portion 321 of the clamping bolt 32 by hand. The movement of the tightening bolt 32 when it is moved and tilted up and down with the rear surface portion of the head 320 abutting on the front surface side of the seat plate 30 as a substantially pivot center, In addition, it is for making it free so as not to cause a restriction due to interference with the inner wall surface of the bolt insertion port 31, and it is sufficient if it is formed in the shape of a long long hole in the vertical direction. Since the movement of the tightening bolt 32 when the tightening bolt 32 is tilted and rotated by hand is small on the head 320 side and large on the screw portion 321 side, as shown in this example, the shape of the long hole The shape of the bolt insertion port 31 is as follows: Be progressively formed transversely of the cone-shaped whose diameter increases toward the consists bolt insertion hole 31 that allows the tilting rotation of the fastening bolts 32 while allowed retaining the strength of the seat plate to be Katachi設.

  In addition, the center point position of the elongated hole-shaped bolt insertion port 31 occupies the intersection of diagonal lines because the fastening bolt 32 is inserted into the seat plate 30 from the opening 10 in the louver a. In the inserted state, as shown by a double-lined arrow in FIG. 23, when the seat plate 30 is rotated clockwise, which is the direction in which the seat bolt 30 is screwed to the center of the fastening bolt 32, the intersection point is obtained. Corner portions between the left and right side edges and the upper and lower edges of the seat plate 30 that rotate about the center are generated by the difference between the vertical width dimension of the seat board 30 and the ceiling height dimension of the louver a. This is to allow the space to rotate with a margin in a free state without interference.

  The tightening bolt 32 to be inserted into the bolt insertion port 31 is in the form of a normal tightening bolt in which the head portion 320 has a nut shape or a disk shape. The seat plate 30 in the mounting bracket c of this embodiment is 10 mm thinner than the upper and lower opening widths of the opening 10 at the rear end of the louver a, and the width dimension between the upper and lower edges. Is 25 mm, which is narrower than 37 mm of the ceiling height of the rear end portion lumen of the louver a, so that the bolt 32 formed by inserting the bolt 32 into the bolt insertion port 31 of the seat plate 30 in the shape of an elongated hole in the vertical direction.
