Abstract

To provide a strut bracket facilitating assembling and mounting even when an installation space and an installation work space are limited.SOLUTION: In a strut bracket 10, a first connection 22 and a second connection 32 of a first strut plate 20 and a second strut plate 30 which are bendable and displaceable are overlapped, and a screw 50 is screwed onto a nut 51 followed by tightening so as to abut a projection 40 disposed in the second connection 32 on the first connection 22, and rotate the second connection 32 toward the first connection 22 side with the recess 40 as a fulcrum. Due to that the second strut plate 30 is inclined to a position of retreating toward an opposite direction to the rotation direction, the second abutting part 32 does not move due to that contact with a second attachment surface 2 is kept, the second strut plate 30 is bent and displaced so as to generate bending stress, and on the basis of the bending stress, strut force is generated in a first abutting part 22 and the second abutting part 32 of the strut bracket 10.SELECTED DRAWING: Figure 4

Description

  The present invention relates to a technique for generating a tensioning force by utilizing a bending stress of a strip-shaped elastic member arranged between abutting surfaces.

  Generally, a tension type tension bracket including a tension rod, a tension frame, etc. is used as a means for installing shelves between opposite wall surfaces without fixing with screws or adhesives and a means for installing equipment in a room. (Patent Documents 1 and 2).

  The bracing bracket described in Patent Document 1 has two frames connected along the longitudinal direction. For example, the total length of both frames is adjusted according to the wall distance at a predetermined interval facing each other, and elastic force of both frames is applied to both frames. Both frames are held between the opposing wall surfaces by a tension force generated by pressing the outer end surface against each wall surface. The bracing bracket described in Patent Document 2 has a configuration in which a ventilation fan is mounted on two bracing bars that form the bracing bracket, and a butting bar is provided on the ventilation fan, and the ventilation fan is installed between the floor and the ceiling. .

  The bracing brackets described in Patent Documents 1 and 2 generate an elastic force along the bracing direction on an elastic member such as a coil spring. In the strut bracket described in Patent Document 1, when a bolt arranged along the strut direction is rotated, an elastic member (piece) arranged on one strut frame is elastically deformed and an elastic force is applied to the other strut frame.

  In the bracing bracket described in Patent Document 2, when one bracing rod is pushed into the other bracing rod, the coil spring contained therein contracts to give an elastic force. For this reason, when installing the equipment, keep one tension bar pressed into the other tension bar in advance, and remove the one tension bar from the hand at the installation position to remove the gap between the floor and the ceiling. Get the thrust force to.

JP, 2013-138818, A JP-A-2000-145687

  By the way, in the conventional bracing bracket, the bracing frame and the bracing rod are arranged at right angles between the wall surfaces to be installed or between the ceiling and the floor to generate a bracing force in the longitudinal direction, so that a relatively large working space is available. Suitable for work in.

  Also, since the bracing frame and the bracing rod are linear, for example, when both bracing frames are used as device mounting surfaces, the flexibility is that both device mounting surfaces are parallel and are installed in different directions like a chevron shape. I can't get it.

  For example, in the case of removing the lining in the interior of an automobile and installing the device inside of the interior, the space for retrofitting the device is often narrow. Therefore, even if an L-shaped bracket or the like is used as in the conventional installation method, a screwable hole for screwing the L-shaped bracket is not necessarily opened in the vicinity of a desired installation location. In addition, if you use an adhesive etc., you may be able to install it in the desired place without worrying about existing holes etc., but you must definitely determine the position at one time, flat and linear surface Other than that, it is difficult to install, and it may be necessary to crimp it to the vertical surface or the top surface until it exhibits adhesive ability. In addition, even when detaching, appropriate knowledge and skill are required for post-processing of adhesives and the like. In addition, screw fastening was the act of driving a screw into a car, which everyone wanted to avoid.

  In such a situation, when the device is installed in a narrow place by the mounting device, the mounting device in which the device is mounted in advance requires a mounting work in a space with a small degree of freedom. Therefore, the attachment device is required to have a structure that can be divided and is easy to assemble.

  However, in the tension frame described in Patent Document 1, the tension frame has a linear structure, and the attachment target portion is limited to two parallel surfaces such as opposing wall surfaces. Further, although the strut frame has a divided structure, since many parts are used, it is difficult to assemble and install the strut frame in a narrow place with a smaller opening than the strut frame.

  Also, in buildings such as dwellings, even though it is an invisible place such as the attic, it is an act that everyone wants to avoid by tapping screws into the dwelling and making holes in walls or the like. Also, since there are cases where pests live in the attic, it is a space that you do not want to enter so much, but you may want to install parts such as equipment for the purpose of exterminating pests, so you can only work near the attic inspection port. There is also a request to complete the installation.

  However, the conventional bracing bracket is premised on installation in a space where there is no obstruction to the installation work, such as between wall surfaces of a room or between a floor and a ceiling, so that it is difficult to assemble it near the attic inspection port. In addition, in the structure in which the piece is screwed forward with the bolt in the reference document 1 and elastic force is applied to the bracing frame, in order to insert a wrench, a screwdriver or the like for tightening the bolt, the hand is inserted deeply into the attic through the attic inspection port. Must be installed and is difficult to assemble.

  Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

First Embodiment In FIG. 1, a bracing bracket 10 includes a first bracing plate 20, a second bracing plate 30, a screw 50, and a nut 51 to which the screw 50 is screwed. The first bracing plate 20 and the second bracing plate 30 are formed in a strip shape (rectangular flat plate shape) by an elastically deformable plate material such as an iron plate. The first bracing plate 20 and the second bracing plate 30 have the same width, and the first bracing plate 20 has substantially the same length as the second bracing plate 30, but may have different lengths or different widths. However, the width and the length are not limited thereto.

  As shown in FIG. 2, the first tension plate 20 has one end in the length direction as the first butting portion 21 and the other end as the first connecting portion 22. In the first tension plate 20, a first plate body 23 having a first abutting portion 21 at an end portion is continuously provided to the first connecting portion 22 via a first step portion 24. The first plate body 23 and the first connecting portion 22 are integrally formed by the first step portion 24 with a step having a height H1 vertically (in the plate thickness direction). In addition, in the state shown in FIG. 2, the first bracing plate 20 has an upper surface as a front surface and a lower surface as a back surface.

  The first connecting portion 22 has elongated holes 25, 25 extending in the length direction on both sides in the width direction, and the first protrusions 26, 26 having a rectangular shape formed by half punching are provided inside the elongated holes 25, 25. It is formed with a space in the width direction. Screws 50 are inserted into the long holes 25, 25. The first protrusions 26, 26 have a recess structure that protrudes toward the front surface side and is recessed on the back surface side. The first protruding portions 26, 26 increase the bending rigidity along the longitudinal direction of the first connecting portion 22.

  As shown in FIG. 3, the second tension plate 30 has one end in the length direction as the second butting portion 31 and the other end as the second connecting portion 32. In the state shown in FIG. 3, the second bracing plate 30 has the upper surface as the front surface and the lower surface as the back surface. The second bracing plate 30 has a second plate body 33 having a second abutting portion 31 at an end thereof and a second step portion 34 that is continuous with the second connecting portion 32. The second connection part 32 has a connection body plate 38 and a retreat plate 39 with a bent part 37 extending in the width direction interposed therebetween. The retreat plate 39 is connected to the step portion 34 and is provided in parallel with the second plate body 33. The bending portion 37 bends the connection body plate 38 with respect to the retreat plate 39 at an obtuse angle (θ). That is, the second bracing plate 30 is arranged so as to retreat to the opposite surface side opposite to the surface side of the second connecting portion 32.

  The second plate body 33 and the retreat plate 39 are integrally formed by the second step portion 34 with a step having a height H2 in the vertical direction (plate thickness direction). The retreat plate 39 causes the second abutting portion 31 to retreat toward the back surface with respect to the convex portion 40, which will be described later, which is a rotational force generating means, at the obtuse angle θ. The height H1 and the height H2 may be the same or different.

  The connection body plate 38 has screw insertion holes 35 on both sides in the width direction into which the screws 50 are inserted in correspondence with the elongated holes 25 of the first connection portion 22, and the nuts 51 are provided on the back surface side of each screw insertion hole 35. It is fixed. Inside the screw insertion holes 35 on both sides in the width direction, angular second protrusions 36, 36 are formed by half punching so as to correspond to the first protrusions 26, 26. The second protrusions 36, 36 have a structure that protrudes toward the front surface side and is recessed on the back surface side. In the present embodiment, the width of the second projecting portion 36 projecting from the surface is formed so as to be slidably fitted into the inner width of the rear surface side recess of the first projecting portion 26.

  On the outer end portion of the connection body plate 38, a convex portion 40 having a height H3 is provided upward along the width direction. The operation of the convex portion 40 will be described below with reference to FIG.

  As shown in FIGS. 1 and 4, in the bracing bracket 10, the first connecting portion 22 of the first bracing plate 20 is superposed on the connection body plate 38 of the second connecting portion 32 of the second bracing plate 30, and the screw 50 is attached. They are passed through the long holes 25, 25 to the screw insertion holes 35, and are screwed into the nut 51. The first strut plate 20 and the second strut plate 30 slide in the longitudinal direction within the longitudinal range of the elongated holes 25, 25 with the screw 50 loosely tightened, so that the entire length of the strut bracket 10 can be adjusted. At this time, since the second protrusion 36 is fitted and guided in the recess on the back surface side of the first protrusion 26, smooth and reliable length adjustment can be performed.

  If the protrusion 40 is not provided on the connection body plate 38, the surface of the connection body plate 38 of the second connection portion 32 comes into contact with the back surface of the first connection portion 22 without a gap when the screw 50 is tightened. That is, the second bracing plate 30 moves in parallel with the first bracing plate 20 and is integrally fixed.

  On the other hand, in the present embodiment, since the convex portion 40 is provided on the surface end portion of the connection body plate 38, when the screw 50 is tightened, the convex portion 40 comes into contact with the back surface of the first connecting portion 22. When the screw 50 is further tightened, the connection body plate 38 rotates toward the first connection portion 22 side with the convex portion 40 as a fulcrum (this rotation direction is the tightening rotation direction). That is, a rotational force that causes the second abutting portion 31 to rotate in the tightening rotational direction around the convex portion 40 is applied to the second tension plate 30.

  The second tension plate 30 is inclined with respect to the connection body plate 38 in the direction opposite to the tightening rotation direction by the bent portion 37 that is bent at an obtuse angle θ with a receding angle θ, and is second in the front-back direction. The abutting portion 31 is located on the back surface side of the convex portion 40.

  FIG. 4 shows a state in which the tension bracket 10 is installed between parallel mounting surfaces of a first mounting surface 1 such as a floor and a second mounting surface 2 such as a ceiling.

(I) shows the setting state in which the first tension plate 20 is arranged on the first attachment surface 1 side, the second tension plate 30 is arranged on the second attachment surface 2 side, and the screw 50 is not yet tightened.
(II) shows a state in which the screw 50 is loosely tightened and temporarily fixed from the setting state of (I). Let L be a perpendicular line passing through the convex portion 40 in the temporarily fixed state and perpendicular to the first mounting surface 1 and the second mounting surface 2, and let M be a linear distance between the second mounting surface 2 and the convex portion 40. The straight line distance (radius) from the second butting portion 31 is R. In this case, since the radius R and the straight line distance M have a relation of R> M, even if the second strut plate 30 is rotated in the tightening rotation direction, the second butting portion 31 causes the second abutting portion 31 to move. And the rotation of the second tension plate 30 is blocked.

  (III) shows the tightening completed state in which the screw 50 has been tightly tightened from the temporarily fixed state of (II), and the tension bracket 10 is installed in a side face substantially "V" shape. When the screw 50 is further tightened from the temporarily fixed state, the connection body plate 38 is pressed against the back surface of the first connection portion 22 in an inclined state with the convex portion 40 as a fulcrum, and the second abutment portion 31 is not removed even if the screw 50 is firmly tightened. It doesn't move. Therefore, bending stress is applied to the first strut plate 20 and the second strut plate 30, and the first butting portion 21 and the second butting portion 31 of the strut bracket 10 are respectively attached to the first mounting surface 1 and the second mounting surface 2. A tension force is generated against. Therefore, the bracing bracket 10 is fixed between the first mounting surface 1 such as the floor and the second mounting surface 2 such as the ceiling.

  In the first bracing plate 20 and the second bracing plate 30, the first projecting portion 26 and the second projecting portion 36 make the bending rigidity of the first connecting portion 22 and the connecting main body plate 38 higher than the bending rigidity of other portions. The bending displacement of the part is increased to obtain an appropriate tension force.

  In this embodiment, the screws 50 are gradually tightened from the temporarily fixed state of the first bracing plate 20 and the second bracing plate 30 to obtain the bracing force based on the bending stress generated in the second bracing plate 30. . Therefore, when setting (assembling) the strut bracket 10 between the attachment target portions, it is not necessary to maintain the state in which the second strut plate 30 is bent in advance with a large force. Further, since the screw 50 can be tightened from the surface side of the tension bracket 10, workability is good.

  Further, when fastening the screw 50, if the fastening is performed while visually observing the first projecting portion 26 of the first bracing plate 20 and the second projecting portion 36 of the second bracing plate 30, the first bracing plate 20 and the second bracing plate It also serves as a guide when 30 is fastened linearly. Further, in the final tightened state where the tightening is completed, the linear fastening of the first bracing plate 20 and the second bracing plate 30 is performed only by visually confirming the fitting of the first projecting portion 26 and the second projecting portion 36. Can be guaranteed, and the reliability of the completion of installation is increased.

  The first abutting portion 21 and the second abutting portion 31 of the bracing bracket 10 have sharp edges in cross section, and combine with the bracing force to play a role of non-slip. In addition, when it is not desired to even damage the contact surfaces of the first mounting surface 1 and the second mounting surface 2 with a slight damage, the first abutting portion 21 and the second abutting portion 31 are provided with a protective member such as a rubber cap. May be attached.

  In the present embodiment, the step portion 24 is provided on the first tension plate 20 and the first void S1 is provided on the back surface side of the first plate main body 23 because the device (not shown) is provided in the first void S1. This is because it is attached. Therefore, when the first void S1 is unnecessary, the stepped portion 24 may not be provided and the first plate body 23 may be directly connected to the first connection portion 22.

  Further, the second tension plate 30 is provided with a second space S2 for mounting a device (not shown) on the back surface side of the second plate body 33 which is inclined with respect to the first plate 23 arranged vertically. If the second space S2 is unnecessary, the step portion 34 may not be provided and the second plate body 33 may be integrated with the retreat plate 39.

Second Embodiment FIGS. 5 to 7 show a second embodiment of the present invention.

  In the present embodiment, a device 120 including a tension bracket is attached to a battery unit 103 housed in a battery case 102 provided in a vehicle interior 101 of a hybrid vehicle 100 by retrofitting.

  As shown in FIGS. 5 and 6, the hybrid vehicle 100 has a battery unit 103 installed between a driver's seat 104 and a passenger seat 105 in a vehicle interior 101. The battery unit 103 is installed upward from the body panel 106. The lower part of the battery unit 103 exists in a space between the floor surface 107 and the body panel 106 where it is difficult to insert a hand.

  As shown in FIG. 6, as a measure against heat, the battery unit 103 is provided with a cooling fan 111 in front of the vehicle body, and intake of air inside the vehicle is performed through intake ports 112 and 113 provided vertically behind the battery unit 103. The structure is such that the cooling is performed (air flows as shown by the arrow). The battery unit 103 is surrounded by a metal protection plate 114, and an upper rear plate 115 provided on the rear surface of the protection plate 114 has an upper intake port 112 formed therein, and a lower rear plate 116 has a lower intake port 113 formed therein. There is. The lower rear plate 116 is arranged such that its lower end side is inclined toward the front of the vehicle, and the upper rear plate 115 is vertically arranged.

  The battery case 102 having a divided structure is arranged so as to surround the protection plate 114, and the gap provided between the inside of the battery case 102 and the protection plate 114 is limited.

  As shown in FIG. 7 (b), the battery case 102 has an opening at the rear portion facing the lower rear plate 116 and the upper rear plate 115, and the rear opening portion 102 A is detachably closed by the rear wall panel portion 102 B. ing.

  In the present embodiment, in order to further improve the cooling effect, a blower fan 121, which is a device, is installed in the gap between the upper rear plate 115 and the lower rear plate 116 and the battery case 102, respectively. 121 is installed in close contact with the upper rear plate 115 and the lower rear plate 116.

  By the way, various covers and the floor surface 107 exist near the upper intake port 112 and the lower intake port 113, and there are many restrictions on the space for installing the blower fans 121. Therefore, there are many obstacles for directly attaching each blower fan 121 to the upper intake port 112 and the lower intake port 113 with screws or the like.

  Further, in the case of installation using an adhesive, there is no problem with space restrictions, but there are problems with post-processing such as adhesive after the bonding, and there is a restriction that positioning must be determined once.

  In this embodiment, as shown in FIG. 7A, the blower fan 121 is attached to a bracing bracket 130 having the same basic configuration as the bracing bracket 10 having the configuration shown in FIG. In the bracing bracket 130 of the present embodiment, members having the same configurations as those of the bracing bracket 10 of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

  The strut bracket 130 makes the width of the first plate body 23 of the first strut plate 20 wider than the width of the first step portion 24, and similarly makes the width of the second plate body 33 of the second strut plate 30 the second step portion. It is made wider than the width of the portion 34. The first plate body 23 has two quadrangular first openings 131 formed in the width direction, and the second plate body 33 has two quadrangular second openings 132 formed in the width direction. A blower fan 121 is attached to the first space S1 of the first plate body 23 and the second space S2 of the second plate body 33 so as to face the first opening 131 and the second opening 132, respectively. . The strut bracket 130 does not include the first protrusion 26 and the second protrusion 36 shown in FIGS. 1 to 3. Therefore, the bending displacement of the first connecting portion 22 and the second connecting portion 32 is facilitated.

  The bracing bracket 130 is arranged inside the body panel 106 and the battery case 102 and between the crosspieces 102C provided above the rear opening 102A. The body panel 106 and the cross section 102C are parallel to each other, and the first butting section 21 of the first strut plate 20 contacts the body panel 106, and the second butting section 31 of the second strut plate 30 contacts the cross section 102C. .

  The lateral width of the rear opening 102A is wider than the lateral width of the strut bracket 130, but the height in the vertical direction is shorter than the height of the strut bracket 130. For this reason, the tension bracket 130 cannot be inserted into the inside of the battery case 102 from the rear opening 102A in the assembled state.

  Therefore, the first bracing plate 20 and the second bracing plate 30 provided with the blower fan 121 in advance are separately inserted from the rear opening 102A behind the upper intake port 112 and the lower intake port 113. At that time, the first butting portion 21 of the first strut plate 20 is butted against the surface of the body panel 106, and the second butting portion 31 of the second strut plate 30 is butted against the lower surface of the crosspiece 102C of the battery case 102. . The first bracing plate 20 is disposed so as to be inclined with respect to the body panel 106, and the second bracing plate 30 is disposed vertically with respect to the crosspiece 102C. In the operation principle diagram shown in FIG. 4, the second tension plate 30 is tilted to generate the bending stress, but in the present embodiment, the first tension plate 20 is tilted to generate the bending stress to obtain the tension force. I am trying.

  The first connecting portion 22 and the second connecting portion 32 are provided at positions facing the rear opening 102A. Then, the screw 50 is screwed into the nut 51 through the elongated hole 25 and the screw insertion hole 35 to temporarily fix the nut 51, and the length of the tension bracket 130 is adjusted. At that time, the first bracing plate 20 is inclinedly arranged along the lower rear plate 116, the blower fan 121 is positioned so as to face the lower intake port 113, and the second bracing plate 30 is vertically arranged along the upper rear plate 115. The blower fan 121 is positioned and positioned so as to face the upper intake port 112. When the positioning is completed, the screws 50 are firmly tightened to generate bending stress in the strut bracket 130, and the striking force based on the bending stress causes the first butting portion 21 and the second butting portion 31 to move to the body panel 106 and the crosspiece 102C. Butt and fix the bracing bracket 130.

  According to this embodiment, the four blower fans 121 can be arranged in the inclined state and the vertical state by the strut bracket 130. The strut bracket 130 can be easily assembled in a narrow space, and since the screw 50 faces the rear opening 102A in particular, the screw tightening operation can be easily performed.

  Further, since the tension bracket 130 can be released from the fixed state only by loosening the screw 50, the position can be corrected while looking at the upper intake port 112 and the lower intake port 113 and the blower fan 121 even after once installed, and the optimum place. It is possible to install it.

Third Embodiment FIG. 8 shows a third embodiment.

  In the third embodiment, a device 150 including a breakthrough bracket in which a disinfecting device 140 that generates electromagnetic waves or ultrasonic waves for harmful insects such as rats is attached to the bracing bracket 10 is installed in the attic 160.

  Pests such as mice may enter the attic of buildings such as ordinary households and warehouses. As a countermeasure, for example, there is a disinfection device that generates electromagnetic waves and ultrasonic waves, and although it is effective in the kitchen and the like, it is ideally installed in the attic. However, the attic is usually a space you don't want to enter, but pests can pass through any part of the attic where wood is placed, so you might want to install it on the attic side of the attic. In this case, it is necessary to have a person standing on the floor of the attic (the ceiling of the room under the attic) while holding the extermination device in his hand, which is an act that one wants to avoid if possible.

  As shown in FIG. 8, the device 150 including the bracing bracket of the present embodiment is installed between the floor of the attic 160 (the ceiling of the room under the attic) 161 and the field board 162. A device 150 having a tension bracket is installed near the inspection port 163 provided on the floor 161. In the bracing bracket 10 of the device 150 of this embodiment, the same members as those shown in FIGS. 1 to 4 are designated by the same reference numerals, and the description thereof will be omitted.

  In the strut bracket 10, the extermination device 140 is attached to the back surface of the second plate body 33 of the second strut plate 30 in advance. The device 150 provided with the strut bracket is inserted into the attic 160 from the inspection port 163 by the worker in a temporarily fixed state, the second butting portion 31 of the second strut plate 30 is brought into contact with the field plate 162, and the first strut is attached. The first abutting portion 21 of the plate 20 is brought into contact with the floor 161.

  At that time, similarly to the second embodiment, the first tension plate 20 is inclined with respect to the floor 161, and the second tension plate 30 is vertical. When the screw 50 is tightened, the connection body plate 38 is bent and displaced in the arrow F1 direction, and a force in the arrow F2 direction acts on the first abutting portion 21, but the first abutting portion 21 cannot move in the arrow F2 direction. . Therefore, due to this bending displacement, bending stress is generated in the bracing bracket 10 as a whole, and the bracing force generated based on the bending stress causes the first abutting portion 21 and the second abutting portion 31 to move to the floor 161 and the ground plate, respectively. The device 150, which is pressed against 162 and comprises a tension bracket, is fixed.

  In the present embodiment, the first plate body 23 of the first tension plate 20 is shortened, and the first connecting portion 22 is brought closer to the inspection port 163. For this reason, the worker, with his / her head slightly out of the inspection port 163 into the attic 160 or with his / her arm out through the inspection port 163, is screwed with the screwdriver of the screw 50 in the operator's hand. Can be tightened. Moreover, since the first tension plate 20 is inclined toward the inspection port 163, the screw tightening work by the driver can be easily performed.

  In addition, when the field board 162 is inclined, a cap that matches the inclination of the field board 162 may be attached to the second abutting portion 31. Further, the second butting portion 31 may be butted against a purlin which is a horizontal girder member to which the field board 162 is attached.

  According to the present embodiment, in the device 150 including the strut bracket, the strut bracket 10 is attached to the extermination device 140 in advance, so that the operator is slightly out of the inspection port 163 of the attic 160, for example. Thus, it becomes possible to install the extermination device 140 at a position close to the field board 162, and it becomes unnecessary for an operator to enter the floor 161 of the attic 160.

Fourth Embodiment FIG. 9 shows a fourth embodiment.

  In this embodiment, a tension bracket 180 is horizontally arranged between a first wall 171 and a second wall 172 which are vertically opposed to each other.

  In the bracing bracket 180 of this embodiment, the same members as those of the bracing bracket 10 shown in FIGS. 1 to 4 are designated by the same reference numerals, and the description thereof will be omitted.

  The bracing bracket 180 of the present embodiment is composed of the first bracing plate 20 and the second bracing plate 30, and differs from the bracing bracket 10 of the first embodiment in the following points.

First Difference In the bracing bracket 10 of the first embodiment, the first connecting portion 22 of the first bracing bracket 20 is superposed on the surface of the second connecting portion 32 of the second bracing bracket 30, whereas the bracing of the present embodiment is made. On the contrary, the bracket 180 has the second connecting portion 32 stacked on the surface of the first connecting portion 22.

Second Difference The tension bracket 180 is provided with a screw insertion hole 25A through which the screw 50 is inserted, instead of the elongated hole 25 provided in the first embodiment in the first connection portion 22, and corresponds to the screw insertion hole 25A on the back surface side. Then, a nut 51 with which the screw 50 is screwed is provided. Further, the connection body plate 38 of the second connection portion 32 is provided with an elongated hole 35A instead of the screw insertion hole 35 provided in the first embodiment, and the nut 51 provided in the first embodiment is omitted. .

Third Difference The bracing bracket 180 is provided with a convex portion 40A on the lower surface side of the first connection portion 22, the convex portion 40 provided at one end of the connection body plate 38 of the first embodiment is abolished, and a new first connection is made. The convex portion 40A provided on the portion 22 is provided closer to the step portion 24 than the screw insertion hole 25A. In addition, the convex portion 40 </ b> A contacts the upper surface side of the connection main body plate 38 within a range in which the second tension plate 30 can slide with respect to the first tension plate 20.

Fourth Difference The screw 50 is screwed into the nut 51 from the elongated hole 35A through the screw insertion hole 25A. The differences are the above-mentioned four points.

  In the present embodiment, the strut bracket 180 is arranged such that the first strut plate 20 and the second strut plate 30 are inclined downward with respect to a horizontal line 173 perpendicular to the first wall 171 and the second wall 172. In the temporarily fixed state, the first butting portion 21 of the first strut plate 20 and the second butting portion 31 of the second strut plate 30 are located below the lower end of the convex portion 40A in the vertical direction and It is in contact with the wall 171 and the second wall 172.

  When the screw 50 is further tightened from the temporarily fixed state, the rear end of the connection body plate 38 comes into contact with the convex portion 40A, and the connection body plate 38 is attracted toward the first contact portion 22 side with the convex portion 40A as a fulcrum. The second bracing plate 30 undergoes bending displacement as a whole upward. At that time, the linear distance between the second butting portion 31 of the second tension plate 30 and the convex portion 40A is R, and the linear distance between the convex portion 40A and the second wall 172 in the horizontal direction is M. Rotational force that acts upward on the convex portion 40A acts on the second abutting portion 31, but because of the relation of R> M, the second abutting portion 31 is kept in contact with the second wall 172. To be done.

  On the other hand, the rotational force directed upward also acts on the first abutting portion 21 of the first strut plate 20, but like the second abutting portion 31, the state in which the first abutting portion 21 is in contact with the first wall 171 is maintained. Therefore, bending stress associated with bending displacement is generated in the tension bracket 180 outward in the longitudinal direction. Then, the first abutting portion 21 and the second abutting portion 31 are pressed against the first wall 171 and the second wall 172 by the tensioning force based on the bending stress, and the tensioning bracket 180 causes the first bracket 171 and the second wall 171. It is fixed between 172.

  In the present embodiment, the surveillance camera 191 that is a device is attached to the upper portion of the portion where the first connecting portion 22 and the second connecting portion 32 overlap. Further, the surveillance camera 191 can be attached to the strut bracket 180, and the S-shaped hook 192 can be attached to the first strut plate 20 and the second strut plate 30 so that the hat 193 or the like can be hooked.

  According to this embodiment, the bracing bracket 180 is installed outdoors, for example, and the surveillance camera 191 is placed on the upper surface, or in the room, a small object such as a hat 193 is attached to the lower surface side of the bracing bracket 180 via the S-shaped hook 192. It is possible to hang it. Even if the strut bracket 180 is heavy, the strut bracket 180 is deformed from the “F” shape to the linear shape, and the axial force based on this deformation is applied to the first butting portion 21 and the second butting portion 31. In addition, the bracing force will be amplified and you can hold objects without falling.

  The third difference is that the convex portion 40A is provided on the lower surface side of the first connection portion 22 and the convex portion 40 provided at one end of the connection body plate 38 of the first embodiment is abolished, but the first embodiment is omitted. Similar to the form, the convex portion 40A may not be provided on the lower surface side of the first connecting portion 22, and the convex portion 40 may be provided at one end of the connection body plate 38.
