Description

  The present invention provides a seat for mounting a device member such as a louver material, a timber material, or a cap wood, which is formed of a metal material such as an aluminum alloy and mounted on the outside or inside of a building structure to the mounting material. The present invention relates to an improvement of a mounting bracket for mounting an apparatus member in a building structure including a plate, a tightening bolt fitted into the plate, and a tightening nut for tightening the tightening bolt.

  Installation of equipment members such as louver materials, mortar materials, and caps, which are molded with metal material and installed on the outside or inside of the building structure, is shown in FIGS. 1 and 2 on the base end side of the device member a. As shown, the mounting portion 1 having a dovetail cross-sectional shape that is continuous in the longitudinal direction is formed as a continuous structure when the device member a is formed by extrusion molding of a metal material such as an aluminum alloy. In addition, the square plate-like seat plate 2 is inserted into the mounting portion 1 in a state in which the head side of the tightening bolt 3 with the head 30 is inserted and inserted into the mounting portion 1. The threaded portion 31 protrudes from the opening 10 with respect to the outside of the groove-shaped mounting portion 1 having a cross section, and the threaded portion 31 of the tightened bolt 3 is arranged in advance at a predetermined location. Through the bolt insertion hole 51 established in the mounting plate portion 50 of the mounting material b to be kept, The tightening nut 4 is screwed onto the screw portion 31 of the tightening bolt 3 and tightened so as to sandwich the rear wall 11 of the groove-shaped mounting portion 1, which is the seat plate 2 and the mounting material b. Is done.

  The mounting bracket c for mounting the apparatus member comprising the seat plate 2, the tightening bolt 3 and the tightening nut 4 for assembling and setting the apparatus member a to the mounting member b is usually as shown in FIG. In addition, the upper and lower heights H formed from a metal plate such as a stainless steel plate have upper and lower openings in the cleaved opening 10 opened on the rear end surface of the mounting portion 1 formed on the base end side of the device member a. A width dimension D that is wider than the width K and that has a width dimension D in the left-right direction that substantially corresponds to the vertical height h of the lumen of the mounting portion 1 is a dimension that forms a substantially rectangular or rectangular shape that is horizontally long in the rear view. As shown in FIGS. 2 and 4, the formed seat plate 2, the tightening bolt 3 with the head 30 inserted into the bolt insertion opening 21 opened at the center portion thereof, and the screw portion 31 of the tightening bolt 3 are shown in FIGS. And a fastening nut 4 that is screwed onto the screw.

  Then, assembling of the device member a to the mounting material b using the mounting bracket c is performed by inserting the square seat plate 2 of the mounting bracket c into the mounting portion 1 of the device member a. The screw portion 31 of the fastening bolt 3 with the head 30 that is positioned so as to be joined to the inner surface of the rear wall 11 and is inserted through the seat plate 2 in advance is attached to the rear wall 11 of the attachment portion 1 of the apparatus member a. The screw part 31 is protruded rearward from the formed opening 10, and the screw part 31 is passed through a bolt insertion hole 51 formed in the attachment plate part 50 of the attachment material b, and the rear surface side of the attachment plate part 50. As shown in FIG. 4, the rear walls 11 and 11 positioned above and below the opening 10 of the device member a are attached to the seat plate 2. And the mounting plate part 50 of the mounting material b.

  As shown in the left half of FIG. 6, the mounting bracket c has a vertical height H that is narrower than the opening width of the opening 10 of the mounting portion 1 of the apparatus member a. The width D of the left and right is formed in a narrow strip shape having a dimension substantially corresponding to the vertical height of the lumen of the rear end portion of the device member a, and this narrow strip-shaped seat plate 2 is formed. Is inserted into the device member a through the opening 10 in a horizontally long posture, and when it is inserted, the seat plate 2 is shown on the right half side of FIG. In addition, there is a configuration in which a fastening with the fastening bolt 3 is performed by converting into a vertically long posture that crosses the opening 10. In this configuration, the seat plate 2 is narrow, so that the contact area with the rear wall 11 of the mounting portion 1 is small, and sufficient strength cannot be obtained during tightening. When the seat plate 2 is rotated with respect to the device member a by the vibration caused by the wind received during use of the device member a assembled by tightening and becomes parallel to the open port 10, the device member a jumps out of the open port 10. This causes a problem that the assembly of the device member a is uncertain. For this reason, the seat plate 2 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 a square plate shape wider than the opening width of the opening 10 into the mounting portion 1 of the device member a of the seat plate 2 is performed with respect to the bolt insertion port 21 of the seat plate 2. When only the seat plate 2 is inserted into the lumen of the mounting portion 1 of the device member a, it is difficult to insert the tightening bolt 3 from the front side of the seat plate 2. In the seat plate 2, the head 30 side of the tightening bolt 3 is inserted into the bolt insertion port 21 of the seat plate 2, and the seat plate 2 in this state is inserted from the edge of the longitudinal end of the device member a. This is done by inserting the seat plate 2 and the head 30 side of the fastening bolt 3 fitted thereto.

  As shown in FIG. 5, the seat plate 2 is inserted into the device member a with the fastening bolt 3 inserted therethrough, and the seat plate 2 is inclined to attach the mounting portion 1 of the device member a. When the rear opening 10 is inserted through the opening 10 in the form of a tear, the screw 31 and the seat plate 2 of the fastening bolt 3 inserted through the seat plate 2 interfere with the upper and lower mouth edges of the opening 10 of the mounting portion 1. Since it cannot be inserted by supporting it, the seat plate 2 through which the tightening bolt 3 is inserted is inserted into the mounting portion 1 of the device member a from the edge of the mounting portion 1. .

  The apparatus member 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 apparatus member a with the attachment metal fitting c at intervals of 50 to 60 cm. This is installed in parallel. A device product such as a louver material, a handrail, a headboard, etc., assembled by assembling the device member a to the mounting material b is usually much longer than the length of one device member a, and there are a plurality of device members a. Can be assembled and assembled.

  Therefore, when the mounting member c composed of the seat plate 2, the tightening bolt 3, and the tightening nut 4 is assembled to the mounting member b in which the device member a is arranged in parallel, the mounting portion 1 of the device member a is fixed. When the seat plate 2 of the mounting bracket c inserted from one edge is first assembled to the mounting material b close to the edge, the seat plate 2 of the mounting bracket c inserted next from the edge is replaced with the next mounting material b. The seat plate 2 of the mounting bracket c to be inserted into the mounting portion 1 from the edge of the mounting portion 1 of the apparatus member a is mounted by the mounting bracket c. Before performing the work of assembling to the material b, it must be coordinated to all of the positions corresponding to each of the mounting materials b in parallel. Moreover, the seat plate 2 through which the fastening bolts 3 of the mounting bracket c prepared in the mounting portion 1 of the device member a corresponding to each mounting material b passes through the mounting portion 1 corresponds to the mounting material b. Even if it moves from the position, it must be moved back 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. When the mounting material b to be assembled is wrong, the seat plate 2 of the mounting bracket c that has become idle due to this cannot be moved to a position corresponding to another mounting material b, jumping over the assembled mounting bracket c. This is because the assembled mounting bracket c must be unwound and redone. For this reason, there is a problem that the work is troublesome in assembling the device member a to the mounting member b using the mounting bracket c composed of the seat plate 2, the tightening bolt 3, and the tightening nut 4. is there.

  The problem to be solved in the present invention comprises a seat plate 2 to be inserted into the mounting portion 1 of the apparatus member a, a tightening bolt 3 to be inserted therethrough, and a tightening nut 4 to be screwed thereto. An object of the present invention is to provide means for solving troublesome problems that have occurred when the apparatus member a is assembled to the attachment material b that can be disposed at the construction site using the attachment metal c.

  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 2 of the mounting bracket c from escaping from the opening 10 on the rear surface of the mounting portion 1 of the apparatus member a when the mounting plate c is tightened by the tightening bolt 3, the height dimension of the mounting plate c is set to the apparatus member. The opening width 10 in the vertical direction of the opening 10 opened in the rear wall 11 of the mounting part 1 of a must be formed larger than the dimension of the opening width in the vertical direction. In this case, it is sufficient if it has sufficient strength, and it may be a normal seat plate thickness dimension smaller than the upper and lower opening width dimensions of the opening 10 on the rear surface of the mounting portion 1.

  The seat plate 2 formed in this way has an oblique posture as long as the clamping bolt 3 inserted through the seat plate 2 does not interfere with and support the upper and lower edges of the opening 10 at the rear end of the device member a. By inserting through the opening 10 at the rear end of the member a, passing through the opening 10 and completing the insertion of the device member a into the mounting part 1, the seat plate 2 is returned to the upright position, Insertion into the attachment part 1 from the opening 10 on the rear surface of the attachment part 1 is possible.

  When the seat plate 2 is in an oblique posture, the tightening bolt 3 is supported on the edge of the opening 10 on the rear surface of the mounting portion 1. If the seat plate 2 can be freely tilted in the vertical direction, the seat plate 2 is inserted into the mounting portion 1 through the opening 10 on the rear surface of the mounting portion 1 in an oblique posture. Sometimes, the fastening bolt 3 is supported by the opening edge 10 of the mounting portion 1 by rotating the fastening bolt 3 with respect to the seat plate 2 so as to be inclined along the rear surface of the seat plate 2. The knowledge that the interference can be eliminated and the seat plate 2 can be inserted into the mounting portion 1 from the opening 10 on the rear surface of the mounting portion 1 has been obtained. 2, the fitting portion between the fastening bolt 3 and the bolt insertion port 21 of the seat plate 2 can be rotated. Although there are various means such as a screw joint, the rotation of the tightening bolt 3 with respect to the seat plate 2 may be performed only in the vertical direction. In order to obtain this vertical rotation, This is because the knowledge that it is sufficient to form the bolt insertion hole 21 in the shape of a long hole that is long in the vertical direction is obtained.

Therefore, in the present invention, as means for solving the above-described problem, a square plate-like seat plate 2 and a fastening with a head 30 fitted into a bolt insertion port 21 provided in the seat plate 2 are provided. A bolt insertion port 21 formed in the seat plate 2 in the mounting bracket c for mounting a louver, comprising a mounting bolt 3 and a tightening nut 4 screwed into a threaded portion 31 of the tightening bolt 3, has a center point However, in the rear view of the square plate-shaped seat plate 2, it is located near the intersection of two virtual diagonal lines connecting two pairs of diagonals, and the width of the right and left of the caliber is fitted into the bolt insertion port 21. It corresponds to the outer diameter of the screw part 31 of the bolt 3 and is formed in the shape of a long hole in the vertical direction in which the vertical width of the aperture is widened in the direction perpendicular to the bottom and top sides of the seat plate 2. The mounting bracket for attaching the apparatus member in the building structure is proposed.
In addition to this, a bolt insertion port 21 for fastening bolt insertion formed in the shape of a long hole in the vertical direction in the rear view is formed on the seat plate 2, and the vertical width of the diameter of the bolt insertion port 21 is The building structure according to claim 1, wherein the building structure is formed in a long hole shape that is small at a portion close to the front surface side of the seat plate 2 and widens up and down as it approaches the rear surface side of the seat plate 2. In this case, a mounting bracket for mounting the device member is proposed.
Further, the rear surface side of the head 30 of the tightening bolt 3 is formed in a projecting portion T that protrudes in an arc shape in a side view, and is tightened to the peripheral portion of the bolt insertion port 21 on the front surface side of the seat plate 2. 2. A building structure according to claim 1, wherein a concave groove w is formed in a side view substantially along the rotation trajectory of the rear surface of the head 30 when the attached bolt 3 is tilted up and down. In this case, a mounting bracket for mounting the device member is proposed.

  The mounting bracket for mounting the apparatus member according to the present invention means that the fastening bolt 3 fitted into the bolt insertion port 21 of the seat plate 2 has the bolt insertion port 21 formed in the shape of a long hole in the vertical direction. Since tilting in the vertical direction can be freely performed with respect to the plate 2, when the seat plate 2 is inserted into the mounting portion 1 of the apparatus member a with the fastening bolt 3 fitted thereto, the fastening is performed. The attached bolt 3 is tilted and rotated with respect to the seat plate 2 so as to be in a posture substantially along the rear surface of the seat plate 2, and in this state, the seat plate 2 is inclined with respect to the opening 10 on the rear surface of the mounting portion 1 of the apparatus member a. By inserting from the opening 10 as a laid posture, it can be inserted into the attachment portion 1 of the apparatus member a.

  As a result, the seat plate 2 of the mounting bracket c can be attached to the rear surface of the mounting portion 1 of the apparatus member a without being restricted by the mounting bracket c already inserted and assembled in a state in which the fastening bolt 3 is fitted. Since it can be inserted into the mounting portion 1 at any time from a desired position in the longitudinal direction of the opening 10, the mounting work of the device member a by the mounting bracket c composed of the seat plate 2, the tightening bolt 3 and the tightening nut 4. It will be possible to solve various problems that have occurred.

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

The provided bolt insertion port, 3 is a fastening bolt to be inserted into the bolt insertion port 21, 30 is the same head portion, 31 is the same screw portion, and 4 is a fastening nut.

  The device member a is a member such as a louver material, a rust material, or a cap wood that is formed of a metal material. In this example, it is a normal metal louver material formed by extrusion processing from a metal material such as an aluminum alloy, and is a type in which the whole is formed into a rectangular tube-shaped square shape, the front and rear width is 120 mm, The top and bottom thickness is 40 mm, and the seat plate 2 of the mounting bracket c is fitted and inserted into the rear portion with the head 30 side of the tightening bolt 3 inserted therethrough. An attachment portion 1 for attaching the device member a to the attachment material b by fastening the fastening nut 4 to be screwed is installed.

  The mounting portion 1 is in a side cross-section in which the opening 10 is opened on the rear surface side and has a groove shape and is configured to be continuous in the left-right direction, which is the longitudinal direction. The upper and lower opening width is 20 mm, and the height h from the inner bottom surface to the ceiling surface is set to 37 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 2 that is formed into a square plate shape from a metal plate such as a stainless plate, a tightening bolt 3 with a head 30 that is fitted into a bolt insertion opening 21 that is opened at the center portion thereof, The fastening nut 4 that is screwed into the screw part 31 of the fastening bolt 3 and fastened is the same as the conventional one, but the mounting bracket c in this example has the dimensions and shape described above. The seat plate 2 is formed so as to be adapted to the mounting portion 1 of the manufactured device member a, and the upper and lower width dimensions of the seat plate 2 in the rear view are the upper and lower openings of the opening 10 on the rear surface of the mounting portion 1. It is 25 mm wider than 20 mm in width, the lateral width on the left and right is 37 mm corresponding to the height dimension h inside the mounting portion 1, and the front and rear thicknesses are the opening width of the opening 10 described above. It is formed in a 12.5 mm square plate shape that is much larger than a half of 20 mm. The size of the seat plate 2 is such that when it is used for the mounting portion 1 having a structure in which the upper and lower opening widths of the opening 10 formed on the rear end surface of the mounting portion 1 are set to 12 mm, the vertical width The size is changed to 16 mm.

  And this seat plate 2 is formed into a horizontally long rhombus on the left and right sides, with the cutting edges 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 is 37 mm corresponding to the internal dimension between the ceiling surface and the bottom surface inside the mounting portion 1 as the horizontal width dimension on the left and right.

  As shown in FIG. 9, the inclination directions of the side edges forming the left and right oblique sides having the seat plate 2 rhombus are set so that the left and right oblique sides are inclined to the right as shown in FIG. When the tightening bolt 3 inserted into the seat plate 2 is rotated in the direction of screwing, the seat plate 2 that rotates following the tightening bolt 3 attaches the left and right oblique sides of the seat plate 2 to the mounting portion 1. It abuts against the inner ceiling surface and the bottom surface to prevent the subsequent rotation of the seat plate 2 so as to be integrally coupled to the mounting portion 1.

  The square plate-shaped seat plate 2 is formed into a horizontally long rhombus that is a slanted side with its right and left sides inclined, and the tightening bolt 3 with the seat plate 2 inserted therein is tightened with screws. By rotating the seat plate 2 in the above-mentioned direction by rotating in the direction, the facing distance is substantially the height dimension from the ceiling surface to the bottom surface of the mounting portion 1 installed at the rear end portion of the device member a. The left and right sides corresponding to each other are brought into contact with the ceiling surface and the bottom surface in the mounting portion 1, respectively, so that the seat plate 2 is fixed in the mounting portion 1. The rotation angle amount is reduced so that a fixed state can be obtained quickly, and the left and right sides of the seat plate 2 are in contact with the ceiling surface and the bottom surface in the mounting portion 1 respectively. Conventionally, in order to make the pivoting operation of the seat plate 2 smooth when it is pivoted to the fixed state, it is shown in FIGS. The mounting portion 1 installed on the rear end of the device member a, which has been produced by cutting the corner portions of the side plate 2 and the upper side obliquely or chamfering in an arc shape, as shown in FIG. The purpose of this is to make the fastening and fixing firmly so as not to reduce the area of the contact portion of the seat plate 2 in contact with the front surfaces of the rear walls 11 and 11. In order to ensure safety when handling the corner portion of the edge of the seat plate 2 formed into a rhombus, chamfering may be performed to such an extent that the area of the contact portion is not reduced.

  The rotation of the seat plate 2 performed to bring the left and right sides of the seat plate 2 into contact with the ceiling surface and the bottom surface inside the mounting portion 1 provided at the end of the device member a is as shown in FIG. Even in the seat plate 2 that is chamfered obliquely or in an arc shape, as in the conventional example, the corners of the side and the upper side are approximately until the left and right sides are in a posture along the horizontal direction. In the seat plate of the embodiment of the present invention means in which the left and right side sides are inclined to be inclined, the seat plate is already provided by the inclination angle of the inclined side. If the seat plate 2 is rotated by the remaining angle obtained by subtracting the inclined angle of the oblique side from 90 degrees, the side is the ceiling surface inside the mounting portion 1. -Since it is in contact with the bottom surface in parallel and fixed to the device member a, the amount of rotation angle of the seat plate is reduced, and the seat plate 2 is To speed up the turning operation until the fixed state mounting member in a.

  The seat plate 2 is formed such that the left and right width dimensions are substantially corresponding to the height dimension from the bottom surface inside the mounting portion 1 at the rear end of the device member a to the ceiling surface. By rotating in the inserted state, the left and right side sides are brought into contact with the ceiling surface and the bottom surface of the lumen of the apparatus member a with the upper and lower sides as upper and lower sides. The part which contacts the front surface of the rear walls 11 and 11 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 2 of this embodiment, the left and right sides which become the upper side and the lower side by rotation are formed as the hypotenuses inclined in the rotation direction, and the hypotenuse is the angle obtained by subtracting the inclination angle from 90 degrees. When the seat plate 2 is rotated together with the seat plate 2, the left and right sides are brought into direct contact with the ceiling surface and the bottom surface of the mounting portion 1, so that one of the left and right sides is inclined. The part cut obliquely by the angle However, on the other side, only the inclination angle is added, and abuts against the front side (inner surface side) of the upper and lower rear walls 11 and 11 facing each other across the opening 10 on the rear surface of the mounting portion 1. There is no reduction in the area of the contact portion on the left and right sides, and therefore the fastening / fixing is strengthened.

  By the way, as for this seat plate 2, the upper and lower both end surfaces are formed in the arc surface as it exists in FIG. 11 from the front edge to the rear edge, Thereby, the fastening bolt 3 is inserted. When the seat plate 2 is in a state of being laid back and forth, the upper and lower end surfaces of the seat plate 2 are placed on the upper and lower sides of the opening port 10 when the seat plate 2 is inserted into the mounting portion 1 from the opening port 10 on the rear surface of the mounting portion 1. It avoids coming into contact with the lip and causing interference. Further, the arc surface formed on the upper and lower end surfaces of the seat plate 2 is formed in a shape that narrows the distance between the upper and lower arc surfaces toward the front, whereby the seat plate 2 is attached to the mounting portion 1. The operation and work when passing through the opening 10 on the rear surface into the mounting portion 1 can be performed more easily.

  Further, on the front surface side of the seat plate 2 of this embodiment, a concave groove w that swells in an arc shape toward the rear surface 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 3 fitted into the bolt insertion port 21 of the seat plate 2 is in the state in which the rear surface side of the head 30 is in contact with the front surface side of the seat plate 2. 2 for smooth rotation operation when tilting in the vertical direction with respect to 2, the rear surface side of the head 30 of the tightening bolt 3 at the left and right central portion of the front surface side of the seat plate 2 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 2, the left and right ends of the seat plate 2 are formed. It is formed as a concave groove w that continues from the end to the other end. For this reason, a portion of the concave groove w that is deviated left and right from a portion facing the rear surface side of the head 30 of the tightening bolt 3 is a play portion having no special function.

  A bolt insertion port 21 formed as an insertion port for the fastening bolt 3 in the seat plate 2 is a long hole with a width corresponding to the outer diameter of the fastening bolt 3 in the vertical direction. In this example, As shown in FIG. 12, in the side view close to the front side of the seat plate 2, 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 3 causes the downward rotation of the tightening bolt 3 to be an elongated hole. This is performed without creating a space for play inside the bolt insertion opening 21.

  As shown in FIGS. 13 to 15, the tightening bolt 3 to be inserted into the bolt insertion hole 21 of the seat plate 2 is formed with the head 30 formed on the rear side on the front side of the seat plate 2. 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 base plate of the mounting bracket for mounting the device member is a square flat plate.

  The mounting bracket for mounting the device member in this example includes a seat plate 2 formed by forming a plate shape made of a metal material such as stainless steel into a square shape, and a bolt insertion opening 21 opened at a central portion of the seat plate 2. It is constituted by a fastening bolt 3 with a head 30 to be inserted and a fastening nut 4 that is screwed into and fastened to a screw portion 31 of the fastening bolt 3 and is formed in a square seat plate 2. The configuration of the bolt insertion port 21 to be formed in the shape of a long hole in the vertical direction in which the tightening bolt 3 inserted in the bolt insertion port 21 can be tilted up and down with respect to the seat plate 2 is different from that of the above-described embodiment. Absent.

  The seat plate 2 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 hypotenuses, and the inclination direction of the left and right sides as hypotenuses thereof is as follows. The fastening bolt 3 inserted into the seat plate 2 is set to be inclined in the direction of screwing, and the inclination angle is approximately 45 degrees.

  As shown in FIG. 20, the mounting plate 1 provided at the end of the device member a has a vertical dimension of 40 mm, the opening width of the opening 10 is 20 mm, It is formed so as to be suitable for the attachment of the device member a which is set to 37 mm from the inner ceiling surface to the bottom surface.

  As shown in FIG. 21, the bolt insertion port 21 for inserting the fastening bolt 3 opened in the seat plate 2 is an intersection of two virtual diagonal lines connecting two pairs of diagonals in the rear view of the seat plate 2. A vertical center with a center point at the position, the width of the right and left of the caliber approximately corresponds to the outer diameter of the screw portion 31 of the tightening bolt 3, and the upper and lower widths of the caliber are widened in the direction perpendicular to the top and bottom sides. It is formed in the shape of a long hole in the direction. Then, as shown in FIG. 20, the elongated hole-shaped bolt insertion port 21 has a small vertical diameter at a portion close to the front surface side of the seat plate 2 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 21 is formed into a long hole shape that is long in the vertical direction. The bolt 3 inserted into the bolt insertion port 21 is held in the vertical direction by holding the screw portion 31 of the bolt 3 by hand. The movement of the tightening bolt 3 when it is moved and tilted up and down with the rear surface portion of the head 30 abutting on the front side of the seat plate 2 as a substantially pivoting center to be laid on the seat plate 2 In addition, it is for free so as not to cause a restriction due to interference with the inner wall surface of the bolt insertion port 21, and may be formed in the shape of a long long hole in the vertical direction. When the clamping bolt 3 is tilted and rotated with the hand held in hand, the movement of the clamping bolt 3 is small on the head 30 side and large on the screw portion 31 side. The lateral direction in which the diameter of the bolt insertion port 21 is gradually increased toward the rear side of the seat plate 2 Be formed in a cone shape, a bolt insertion hole 21 to allow the tilting rotation of the fastening bolt 3 while allowed retaining the strength of the seat plate will be able to form set.

  Further, the central point position of the elongated hole-shaped bolt insertion port 21 occupies the intersection of the diagonal lines because the fastening bolt 3 is inserted into the seat plate 2 and the opening 10 is inserted into the mounting portion 1. 23, when the seat plate 2 is rotated clockwise, which is the direction of screw tightening around the center of the tightening bolt 3, as indicated by the double line arrow in FIG. The corner portions of the left and right sides and the upper and lower edges of the seat plate 2 that rotate about the intersection point are caused by the difference between the vertical width of the seat plate 2 and the height of the ceiling in the mounting portion 1. This is to rotate the generated space with a margin in a free state without interference.

  The tightening bolt 3 to be inserted into the bolt insertion port 21 is in the form of a normal tightening bolt in which the head 30 thereof has a nut shape or a disk shape. The seat plate 2 in the mounting bracket c of this embodiment has a thickness of 10 mm, which is thinner than 20 mm of the opening width above and below the opening 10 on the rear surface of the mounting portion 1 provided at the rear end of the device member a. Since the width between the upper and lower edges is 25 mm, which is narrower than 37 mm of the ceiling height inside the mounting portion 1, the tightening bolt 3 inserted into the bolt insertion port 21 of the seat plate 2 is attached in the vertical direction. Utilizing the shape of the bolt insertion hole 21 formed in the shape of a long hole, the seat plate 2 is tilted in the vertical direction with respect to the seat plate 2 so as to follow the outer surface of the seat plate 2, and the seat plate 2 in this state is laid down diagonally. Thus, by passing through the opening 10, it can be inserted into the attachment 1 from the opening 10 on the rear surface of the attachment 1. When the insertion of the tightening bolt 3 is returned to the old position after the insertion, and the rotation of the tightening bolt 3 in the screw tightening direction, the seat plate 2 that rotates together with the tightening bolt 3 has an angle of approximately 45 degrees. The left and right sides that incline when the amount is rotated come into contact with the ceiling surface and the bottom surface inside the mounting portion 1 and are fixed to the apparatus member a.

  The mounting bracket c can be used as it is for mounting the device member of the mechanical device as long as the mounting portion having the same structure as the mounting portion 1 is mounted on the end portion.
