  As shown in FIGS. 2 and 3, the louver mounting bracket c for assembling the louver a to the mounting material b has a vertical height H from a metal plate such as a stainless steel plate. The width D in the left-right direction forms the opening 10 of the louver a with a width wider than the upper and lower opening widths K of the cleaved opening 10 formed between the upper and lower rear walls 11 of the rear end face. And a seat plate 30 formed in a shape that is substantially rectangular or rectangular horizontally long in the rear view, which is a dimension that substantially corresponds to the vertical height h of the inner dimension on the rear end side, and is established in the central part of this. The bolt insertion port 31, the tightening bolt 32 with the head portion 320 inserted through the bolt insertion port 31, and the tightening nut 33 screwed into the shaft-shaped screw portion 321 of the tightening bolt 32.

  The mounting of the louver a to the mounting member b using the mounting bracket c is performed in the louver a with the square seat plate 30 of the mounting bracket c and the head side of the tightening bolt 32 inserted therein. The screw portion 321 of the tightening bolt 32 with the head portion 320 inserted through the seat plate 30 is inserted into the rear wall 11 of the louver a so as to be joined to the inner surface of the rear wall 11 of the louver a. The screw part 321 is protruded rearward from the opening 10 formed in the shape, and the screw part 321 is passed through the bolt insertion hole 21 formed in the attachment plate part 20 of the attachment material b, and the rear surface of the attachment plate part 20 As shown in FIG. 4, the rear walls 11 and 11 positioned above and below the opening 10 of the louver a are attached to the seat plate by protruding to the side and screwing the tightening nut 33 into the screw portion 321 and tightening. 30 and the mounting plate 20 of the mounting material b, and fixedly mounted. It is carried out in the Rukoto.

  The louver mounting bracket c for assembling the louver a to the mounting member b is usually provided with a seat plate 30 having a vertical height H above and below the opening 10 on the rear end face of the louver a. A rectangular or rectangular corner that is slightly larger than the opening width K and whose left and right width dimension D corresponds to the height dimension h from the upper surface of the floor plate 12 to the lower surface of the top plate 13 in the rear end of the louver a. The corner portion located in the front direction of rotation when the seat plate 30 is rotated by the fastening bolt 32 with respect to the center line y on the left and right sides is shaped like an arc or an oblique side. In this state, the seat plate 30 is inserted into the fastening bolt 32 so that the screw portion 320 of the fastening bolt 32 protrudes rearward from the opening 10 at the rear end of the louver a. The longitudinal edge of the Then, the seat plate 30 is inserted into the rear end portion of the louver a, slid to a predetermined position, and the screw plate 320 of the tightening bolt 32 protruding from the opening 10 is operated at that position, whereby the seat plate 30 is substantially omitted. As shown on the right side of FIG. 3, the left and right sides are fixed to the upper surface of the floor plate 12 of the louver a and the lower surface of the top plate 13, respectively. The seat plate 30 is fastened and fixed to the louver a by inserting the screw portion 320 of the attached bolt 32 through the bolt insertion port 31 provided in the attachment material b and screwing and tightening the fastening nut 33. Thus, the louver a is assembled to the attachment material b.

  At this time, the insertion of the seat plate 30 into the louver a is performed with the tightening bolt 32 inserted. If only the seat plate 30 is inserted into the louver a first, the seat plate 30 is tightened. This is because the bolt 32 cannot be inserted into the bolt insertion opening 31 of the seat plate 30 with the head 320 positioned inside the seat plate 30.

  The insertion of the seat plate 30 through which the tightening bolt 32 is inserted into the louver a from the edge of the longitudinal end portion of the louver a is made when the seat plate 30 is laid down from the opening 10 as a laid posture. As shown in FIG. 5, the fastening bolt 32 inserted through the seat plate 30 is supported by the opening edge of the louver a so that it cannot be inserted.

  The mounting plate c for mounting the louver has a seat plate 30 formed in a rectangular or rectangular square plate shape in a state where the fastening bolt 32 is inserted and is in a horizontally long posture from the edge of the louver a to the louver. When the screw is inserted into a, and the screw portion 320 of the tightening bolt 32 protruding from the opening 10 of the louver a is operated, it is slid along the opening 10 while maintaining a horizontally long posture. , The left and right sides are brought into contact with the floor plate 12 and the top plate 13 of the louver a to be in a fixed state, and in this state, the fastening nut 33 is used for fastening. In order to make the rotation of the seat plate 30 in the lumen of the louver a smooth at the corner portions of the left and right side edges and the upper and lower edges, arc-shaped or oblique cut portions are provided.

  The part where the seat plate 30 is tightened by tightening the tightening nut 33 screwed into the tightening bolt 32 is on the right half side of FIG. An intermediate portion that is only the upper and lower end edges that overlap with the inner surfaces of the upper and lower rear walls 11, 11 of the louver a when rotating to abut against the floor surface, and that faces the opening 10. Does not act on the fastening.

  For this reason, the mounting bracket c of this embodiment has a corner portion of the seat plate 30 cut out so that the operation when the seat plate 30 inserted into the louver a is rotated 90 degrees is correctly performed. There is a problem in that the fastening is weakened by reducing the area of the portion that performs the fastening operation by the amount of the cut.

  The inserted seat plate 30 is rotated 90 degrees in the tightening direction around the center of the tightening bolt 32 inserted in the seat plate 30 so that the left and right sides collide with the floor surface and the ceiling surface of the louver a, respectively. However, at this time, due to an error in the production of the seat plate 30, the left and right width dimensions do not correctly match the height dimension from the floor surface to the ceiling surface of the louver a, or If the corner plate is not sufficiently cut out, the left and right side sides before the seat plate 30 rotates 90 degrees and the left and right sides come into contact with the floor surface and the ceiling surface of the louver a. Is supported by the floor / ceiling surface of the louver a and the rotation is prevented, or it is rotated more than 90 degrees and part of the left and right sides are supported by the floor / ceiling surface. As a result, the seat plate 30 is fixed in an inclined state. - there is a problem to incomplete fixation.

  In addition, there is a problem that it is difficult to correctly rotate the seat plate 30 by 90 degrees so that the left and right sides are parallel to the floor surface and the ceiling surface of the louver a.

  The seat plate 30 of the mounting bracket c for mounting the louver has a width dimension H of the upper and lower openings of the opening 10 on the rear end surface of the louver a, as in the seat plate of the example shown in FIG. There is also a configuration that can be inserted into the louver a through the opening 10 at the rear end surface of the louver a in a state where the width is narrower than that and the fastening bolt 32 is inserted.

  The seat plate 30 of the mounting bracket c for mounting in this form is the same as that of the above-mentioned form in that it is formed into a square plate shape from a metal plate such as a stainless steel plate. In FIG. 6, the left and right width dimension D substantially corresponds to the height dimension h from the upper surface of the floor plate 12 to the lower surface of the top plate 13 of the rear end portion of the louver a, as shown on the left half side of the figure. Is formed in the shape of a narrow strip having a width H that is narrower than the opening width K above and below the opening 10 at the rear end face of the louver a, whereby the seat plate 30 with the tightening bolt 32 inserted is formed. When the louver a is inserted into the louver a from the opening 10 at the rear end of the louver a, and the insertion is completed, the left and right sides are made to rotate as shown in the right half of FIG. Each louver collides with the upper surface of the floor plate 12 and the lower surface of the top plate 13 inside the louver a. Becomes cathodic state between the inner wall surface of the upper and lower rear wall 11, 11 to form an open mouth 10 of the rear end face of a, is of the form so that a fixed state with respect to the louver a.

  The seat plate 30 of the mounting bracket c of this embodiment is inserted into the louver a with the fastening bolts 32 fitted, and the left and right sides are in contact with the floor surface and the ceiling surface of the louver a in parallel. In order to ensure that the pivoting operation is correctly performed, the cut portion formed in the corner portion reduces the effective contact area when tightening the seat plate 30 and weakens the fastening. Due to manufacturing errors, it is difficult to insert the seat plate 30 into the louver a and to rotate it 90 degrees correctly to the position where the left and right sides are in contact with the floor and ceiling surfaces of the louver a. However, it is the same as the seat plate 30 of the mounting bracket c of the above-described form.

  Moreover, the louver a fastened is formed by forming the seat plate 30 into a strip-like piece whose upper and lower width dimensions are narrower than the opening width of the opening 10 so that the seat plate 30 can be inserted from the opening 10 of the rear end surface of the louver a. When the seat plate 30 is rotated to a posture along the opening 10 due to the loose rotation of the seat plate 30 due to vibration of the wind, etc., the louver a comes out of the opening 10. There is a problem that makes the assembly of the uncertain.

  The problems to be solved in the present invention are a seat plate 30 formed in a square plate shape, a tightening bolt 32 inserted into a bolt insertion port 31 provided in the seat plate 30, and a screw portion 320 of the tightening bolt 32. In the mounting fitting c for louver attachment comprising a fastening nut 33 that is screwed onto and tightening, the seat plate 30 that is inserted into the louver a with the fastening bolt 32 inserted is inserted into the left and right sides thereof. When the louver a is rotated to a posture in which the floor surface and the ceiling surface are opposed to each other in parallel, the operation of smoothly rotating the seat plate 30 is reduced to an effective fastening area when the seat plate 30 is fastened. And the seat plate 30 is rotated to a state in which the left and right sides of the seat plate 30 face each other in parallel with the floor surface and the ceiling surface of the louver a. Is easy to obtain .

  The means of the present invention for solving the above-mentioned problems has been made on the basis of knowledge obtained by variously examining the shape and function of the seat plate of the mounting bracket for mounting the louver.

  In other words, the seat plate formed in the shape of a square plate has a shape in which the left and right sides are inclined to the rotation direction of the screw tightening of the tightening bolt, and the interval between the inclined sides is assembled. Formed into a rhombus with dimensions corresponding to the height from the floor to the ceiling of the louver, and opened a bolt insertion port for inserting the tightening bolt so that the center point is located near the intersection of the diagonal lines If so, insert the seat plate into the louver, rotate the seat plate around the center of the bolts that have been inserted, and the left and right sides are parallel to the floor and ceiling surfaces inside the louver. When changing to the facing state posture, the corner part of the seat plate that interferes with the floor and ceiling surfaces inside the louver and causes support is cut off by making the left and right sides beside. Therefore, the rotation of this seat plate can cause support. Not be carried out smoothly. And the corner part of the seat board used as this cut-off state will be in the added state in the opposite side. For this reason, the interference of the corner part at the time of rotating and changing the posture is eliminated without causing a reduction in the area of the seat plate.

  Then, the left and right side sides are formed on the hypotenuse that inclines the seat plate in the rotational direction, and as shown in FIG. In other words, since the seat plate 30 has already been rotated by 45 degrees, the left and right sides are the floor of the louver a, just as it is rotated by 45 degrees, just as it is rotated by 90 degrees. Since it is in a state parallel to the surface / ceiling surface, the rotation operation of the seat plate 30 for posture change is completed with a small amount of rotation angle. It was made on the basis of the knowledge that was obtained.

And from this, in the present invention, as means for solving the above-mentioned problems,
