JP 2001-101585 A

  However, the suspension device as in Patent Document 1 has a fall prevention wire 26a that is pulled between the upper and lower mounting portions when an external force is applied to the housing 7 and the mounting portion between the support column and the housing 7 is damaged. There was concern about the risk of 26b being cut by contact with an edge of the housing 7 or a component housed in the housing 7.

  The present invention provides an installation structure for a sign body that can more reliably prevent the sign body from falling when a portion fixed to the support is damaged.

In order to achieve the above object, the present invention is configured as follows.
That is, the installation structure of the sign body according to the present invention is an installation structure of the sign body that is attached to the upright support column via the mounting bracket,
A plurality of wire fixing portions are formed on the outer surface of the marking body, and one end portion of the fall prevention wire is fixed to each wire fixing portion,
A support wire fixing portion is formed on the outer surface of the support column, and the other end of each fall prevention wire is fixed to the support wire fixing portion.

According to the installation structure of the sign body according to the present invention, the wire fixing part for fixing one end of the fall prevention wire is formed on the outer surface of the sign body, and the post for fixing the other end of the fall prevention wire. Since the wire fixing part is formed on the outer surface of the column, when the mounting bracket that attaches the marking body to the column breaks, etc., when the fixing of the marking unit to the column is released, the tension drop prevention wire is not attached to other articles. It is difficult to touch and to be cut.
In addition, a plurality of the wire fixing portions are formed on the outer surface of the marking body, and the fall prevention wires each having one end fixed thereto are fixed to the column fixing portion, so that the marking body can be fixed to the column. Even when one of the pulled fall prevention wires is broken when it comes off, the sign body can be prevented from falling by suspending the sign body with the remaining fall prevention wires.

In addition, each of the support wire fixing portions is formed in a set of two on the left and right lateral sides of the support column, and one end of the support wire fixing portion is fixed to the other end of each of the fall prevention wires. If the end of the wire is fixed to each wire fixing portion of the marking body attached to the front side of the column, each of the pulled fall prevention wires is marked when the fixation of the marking body to the column is removed. This is preferable because it is difficult to contact the outer surface of the body and each fall prevention wire is hardly cut.
Further, if the size of the left and right spacing of each wire fixing portion is larger than the left and right spacing of each support wire fixing portion, when the fixing to the support is released and the indicator moves in the horizontal direction, Since the state in which the fall prevention wires are strongly pulled at the same time is less likely to occur, the problem that all the fall prevention wires are cut at the same time can be suppressed, which is preferable.
In addition, if the cross section of the column is formed in a circular shape or an elliptical shape, the fall prevention wire comes into contact with the corner portion of the column when the fixing of the marking body to the column is released and each fall prevention wire is pulled. Since there is no, the cutting | disconnection of each fall prevention wire is suppressed and it is preferable.

  In addition, a groove portion in which the bolt / nut can be inserted without being removed is formed in the sign body, and the sign body is attached to the column via the mounting bracket attached by the bolt / nut inserted into the groove portion. If each said wire fixing part is arrange | positioned on the right-and-left side of the said bolt and nut and it fixes to the said groove part, since each said wire fixing part can be easily provided in a sign body, it is preferable.

In addition, if the indicator is provided with a light emitter, and a solar cell unit that generates electric power to emit light from the light emitter is disposed above the indicator and attached to the support, an environmentally friendly light emission indicator can be provided. This is preferable because it is possible.
In addition, the solar cell unit is formed with a plurality of wire fixing portions, and one end portion of the fall prevention wire is fixed to each of the wire fixing portions, and the support wire fixing portion is formed on the support column. It is preferable to fix the other end portion of each of the fall prevention wires to the fixing portion, since not only the marking body but also the solar cell unit can be prevented from falling.

  According to the installation structure of the sign body according to the present invention, the sign body can be more reliably prevented from dropping when the sign body is fixed to the support.

3 and 4, the sign body 2a is enlarged and illustrated among the two sign bodies 2a and 2b, but the sign body 2b is installed in the same manner as the sign body 2a.
Grooves 21 are formed on the rear surface of the marking body 2 so as to face in the horizontal direction.
The groove portion 21 is provided in a bag groove shape in which the size of the width on the back side of the groove is larger than the size between the opening edges of the opposite groove, and the mounting bolt B2 inserted from the end of the groove portion 21 is provided. The head is housed in such a manner that it cannot be removed from the opening and is slidable along the groove.
The marking body 2 is provided with the groove 21 by fixing a groove fitting 22 having the groove 21 to the rear surface.
A total of four groove fittings 22 are arranged on the marking body 2a, which is provided in the form of a vertically long rectangular plate, with a gap in the vertical direction.
A total of two of the groove fittings 22 are arranged on the marking body 2b, which is provided in a substantially square plate shape, with an interval in the vertical direction.

The mounting bracket 82 is attached to the marking body 2 with a mounting bolt B2 in which a head is inserted into the groove portion 21 and a male screw portion protrudes backward.
The mounting bracket 82 is a so-called U-shaped bracket having a substantially U-shaped cross section, and has a U-shaped plate portion 82a formed in a U-shape and extends laterally outward from both ends thereof. A mounting plate portion 82b is formed.
The mounting bracket 82 abuts the inner surface of the U-shaped plate portion 82a to the rear side of the support column 1, and screws the nut N2 to the male screw portion of the mounting bolt B2 inserted through the through hole of each mounting plate portion 82b. By doing so, it is attached to the sign body 2 and the sign body 2 is attached to the column 1.

A wire fixing portion 23a is formed on the rear surface of the marking body 2, and one end of the fall prevention wire 92 is fixed to the wire fixing portion 23a.
The wire fixing portion 23 a is formed on the wire fixing bracket 23, and the wire fixing portion 23 a is formed on the marking body 2 by fixing the wire fixing bracket 23 to the rear surface of the marking body 2.
The wire fixing bracket 23 is formed by bending a metal plate, and includes a mounting plate portion 23c that is fixed to the rear surface of the marking body 2, and a separation portion 23b that extends rearward from the upper end of the mounting plate portion 23c. The wire fixing portion 23a extending upward from the rear end of the spacing portion 23b is formed.

The wire fixing bracket 23 is attached to the marking body 2 by a mounting bolt B2 in which a head is inserted into the groove portion 21 formed on the rear surface of the marking body 2 and a male screw portion is protruded rearward.
Specifically, the male screw portion of the mounting bolt B2 is inserted through the through hole of the mounting plate portion 23c, and the nut N2 is screwed to fix the wire fixing bracket 23 to the rear surface of the marking body 2.
Two wire fixing metal fittings 23 are arranged on the side of the attachment metal fitting 82 attached to the groove portion 21 one by one, and are fixed to the marking body 2, and the wire fixing portion 23a of each wire fixing metal fitting 23 is fixed. The lower ends of the two fall prevention wires 92 are fixed respectively.

Ring portions 92a that can be easily attached to metal fittings such as shackles are formed at both ends of the fall prevention wire 92, respectively. Each ring portion 92a is formed in a ring shape by folding back the end of the wire that constitutes the fall prevention wire 92, along the wire, and by caulking a fitting 92b attached so as to surround them.
The fall prevention wire 92 is fixed by attaching a lower ring portion 92 a to a shackle 72 attached to a through hole of the wire fixing portion 23 a of the sign body 2.

The fall prevention wire 92 is fixed by attaching its upper end to the support wire fixing part 12 of the support 1.
The support wire fixing portions 12 are provided in a plate shape having through holes 12 a, and two support wire fixing portions 12 are formed on each of the left and right sides of the support 1. Specifically, a plate-shaped metal fitting constituting the support wire fixing portion 12 is fixed to the support 1 by welding.
Shackles 71 are respectively attached to the through holes 12a of the support wire fixing portions 12, and the ring portions 92a at the upper ends of the fall prevention wires 92 are attached and fixed to the shackles 71.

Although the marking body 2 is attached to the support column 1 via the mounting bracket 82, there is a possibility that the mounting bracket 82 may be fixed due to a collision of a vehicle, a flying object, or the like with the marking body 2.
When the fixing body 82 is unfixed by the mounting bracket 82, the marking body 2 is suspended from the support column 1 by a fall prevention wire 92 having both ends attached to the wire fixing portion 23a and the support wire fixing portion 12 of the support column 1, The fall from 1 can be prevented.

As shown in FIG. 4, the marking body 2 is arranged such that the left and right intervals of the wire fixing portions 23 a provided on the rear surface side are larger than the left and right intervals of the support wire fixing portions 12 provided on the support columns 1. I am letting.
For this reason, each of the fall prevention wires 92 is arranged in a “C” shape so that the distance between the fall prevention wires 92 increases downward. In other words, the two fall prevention wires 92 are parallel to each other. Instead, the other is inclined with respect to the other.
By disposing each fall prevention wire 92 as described above, when the marking body 2 is moved laterally from the column 1 by being fixed by the mounting bracket 82, even if one fall prevention wire 92 is pulled, the other If the fall prevention wires 92 are loosened, the problem that the fall prevention wires 92 are simultaneously cut is less likely to occur, and the fall of the marking body 2 can be prevented more reliably.

  Further, the marking body 2 has the mounting plate portions 82b of the mounting bracket 82 arranged on the left and right sides of the support column 1, respectively, and the mounting bracket 82 is mounted by the mounting bolts B2 inserted through the mounting plate portions 82b. , Attached to the column 1. For this reason, if the mounting bolts B2 are not broken or removed from the groove portion 21 at the same time, the marking body 2 removed from the support column 1 moves not in the forward direction but in either the left or right direction including the diagonal direction. The problem that both the fall prevention wires are both pulled and cut at the same time is less likely to occur, and the marking body 2 can be more reliably prevented from falling.

In addition, the sign body 2 that has been unfixed by the mounting bracket 82 can be easily moved in any one of the left and right directions including the oblique direction, not the rear side in contact with the support column 1. For this reason, in the installation structure of the sign body 2 in which the pillar wire fixing portions 12 are respectively formed on the left and right sides of the pillar 1, when the sign body 2 moves away from the pillar 1, each fall prevention unit that connects the two is provided. Since the wire 92 is less likely to come into contact with articles other than the support column 1, the fall prevention wire 92 is less likely to be cut.
Further, since the support column 1 has a circular cross section and does not have corners, cutting of the fall prevention wire 92 that contacts the outer surface of the support column 1 is suppressed.

5 is an enlarged side view showing the solar cell unit 4 portion of FIG. 2, and FIG. 6 is a rear view of FIG.
In FIGS. 5 and 6, the illustration of the marking body 2, the fall prevention wire 92, and the shackle 71 is omitted, and the drawings are simplified.

However, the present invention is not limited to this, and the upper end portion 11 having a smaller diameter than the support column 1 may be provided so as to be inserted and accommodated in the shaft attachment portion 41.
Further, the solar cell unit 4 is provided so that the upper end portion 11 of the support column 1 is inserted into the inner side of the shaft attachment portion 41, but the present invention is not limited to this. The solar cell unit 4 may be rotatably attached to the support column 1 by inserting the portion 41.

A wire fixing portion 43a is formed in the solar cell unit 4, and one end of the fall prevention wire 94 is fixed to the wire fixing portion 43a.
The wire fixing portion 43 a is formed on the wire fixing bracket 43, and the wire fixing portion 43 a is formed on the solar cell unit 4 by fixing the wire fixing bracket 43 to the back surface of the solar cell unit 4.
The wire fixing bracket 43 is formed by bending a metal plate in the same manner as the wire fixing bracket 23. The mounting plate portion 43c is fixed to the back surface of the solar cell unit 4, and the end of the mounting plate portion 43c. A separation portion 43b extending vertically from the wire and a wire fixing portion 43a extending vertically from the end of the separation portion 43b are formed.

The wire fixing bracket 43 is attached to the back surface of the solar cell unit 4 by means of a mounting bolt B4 attached to the solar cell unit 4.
Specifically, the mounting bolt 4 has a bolt head attached to the back surface of the solar cell unit 4 so that the male screw portion protrudes in a direction perpendicular to the back surface of the solar cell unit 4.
The wire fixing bracket 43 allows the male screw portion of the mounting bolt 43 to be inserted into the through hole of the mounting plate portion 43c and the nut N4 is screwed to fix the wire fixing bracket 43 to the back surface of the solar cell unit 4. Yes.
Two wire fixing metal fittings 43 are arranged on the left and right sides of the shaft attachment portion 41, one in total, and fixed to the solar cell unit 4, and two wire fixing metal fittings 43 are connected to the wire fixing portion 43a. The upper ends of the book fall prevention wires 94 are fixed respectively.

  At the ends on both sides of the fall prevention wire 94, similarly to the fall prevention wire 92, a ring portion 94a that can be easily attached to a metal fitting such as a shackle by caulking the end of the folded wire with a caulking metal fitting 94b. Respectively. Each fall prevention wire 94 is fixed by attaching an upper ring portion 94a to a shackle 74 attached to a through-hole of the wire fixing portion 43a of the solar cell unit 4.

The fall prevention wire 94 is fixed by attaching its lower end to the support wire fixing portion 14 of the support 1.
The support wire fixing portions 14 are provided in a plate shape in which through holes are formed, and a total of two support wire fixing portions 14 are formed on each of the front and rear sides of the support column 1. Specifically, like the support wire fixing part 12, a plate-shaped metal fitting constituting the support wire fixing part 14 is welded and fixed to the support 1.
Shackles 71 are attached to the through holes of the support wire fixing portions 14, and ring portions 94 a at the upper ends of the fall prevention wires 94 are attached and fixed to the respective shackles 71.

  Each fall prevention wire 94 shown in FIG. 5 has its lower end fixed only to the column wire fixing part 14 formed on the rear side of the column 1, but is not limited thereto. In the solar cell unit 4, the positions of the two wire fixing portions 43a and the two support wire fixing portions 14 are changed by adjusting the orientation for directing the light receiving surface to the south side. Thus, the lower ends of the two fall prevention wires 94 may be fixed only to the support wire fixing portion 14 formed on the front side of the support column 1 or may be fixed to the two support wire fixing portions 14 respectively.

FIG. 7 is a view showing a state in which the solar cell unit 4 of FIG.
The shaft attachment portion 41 of the solar cell unit 4 is provided so that it cannot be removed from the upper end portion 11 of the support column 1 unless the fall prevention wire 94 is fixed.
The solar cell unit 4 inserts the upper end portion 11 of the support column 1 into the inside of the cylindrical shaft mounting portion 41, and connects the upper and lower ring portions 94a of the two fall prevention wires 94 to the wire fixing portion 43a and the support wire, respectively. Although it is fixed to the fixing portion 14, when the screw B <b> 3 is loosened and the pivoting portion 41 is moved upward, the fall prevention is performed before the upper end portion 11 of the support column 1 comes out from the inner side of the pivoting portion 41. The wire 94 is pulled to the limit and restricts the movement of the pivoting portion 41.
The solar cell unit 4 can suppress the state where the fixing to the upper end portion 11 is released by the respective fall prevention wires 94, and can prevent the fall from the support column 1.

  Since the column 1 and the upper end portion 11 and the shaft mounting portion 41 of the solar cell unit 4 are each circular in cross-section and have no corners, the solar cell unit may collide with vehicles or flying objects. When 4 moves, the problem that the fall prevention wire 94 contacts and is cut | disconnected by the corner | angular part of a support | pillar or a shaft attachment part can be prevented.

FIG. 8 is an enlarged side view showing the fall prevention wire 95 portion of the control box 5 of FIG. 2, and FIG. 9 is a front view of FIG.
In FIGS. 8 and 9, the marking body 2 and the mounting bracket 82 are not shown, and the drawings are simplified.
Grooves 51 are formed on the front surface of the control box 5 in the horizontal direction.
The groove portion 51 is formed in the same manner as the groove portion 21 of the sign body 2, and specifically, the head of the mounting bolt B5 inserted from the end of the groove 51 is stored in an unremovable manner from the opening, It is provided in a bag groove shape that can slide along the groove.
The control box 5 is provided with the groove 51 by fixing the groove fitting 52 formed with the groove 51 to the front surface, and two groove fittings 52 are arranged at intervals in the vertical direction. The groove fitting 52 is formed in the same cross-sectional shape as the groove fitting 22.

The mounting bracket 85 is formed in the same shape as the mounting bracket 82 and is mounted to the control box 5 by the same method.
That is, the mounting bracket 85 is a U-shaped bracket including a U-shaped plate portion 85a formed in a U-shape and a mounting plate portion 85b extended from the end to the lateral side. The inner surface of the portion 85a is brought into contact with the support column 1, and the nut N2 is screwed to the male screw portion of the mounting bolt B5 inserted through the through hole of each mounting plate portion 85b. The control box 5 is attached to the column 1.

A wire fixing portion 53a is formed in the control box 5, and one end portion of the fall prevention wire 95 is fixed to the wire fixing portion 53a.
The wire fixing part 53 a is formed in the wire fixing metal 53, and the wire fixing part 53 a is formed in the control box 5 by fixing the wire fixing metal 53 to the front surface of the control box 5.
The wire fixing metal 53 is formed in a plate shape having a through hole in the upper part, and the upper part in which the through hole is formed protrudes upward from the upper surface of the control box 5 to form the wire fixing part 53a. The lower part is fixed to the front surface of the control box 5 by screwing.

At both ends of the fall prevention wire 95, ring-shaped ring portions 95a are formed using caulking fittings 95b, similarly to the fall prevention wires 92 and 94.
The fall prevention wire 95 is fixed by attaching a lower ring portion 95 a to a shackle 75 attached to a through hole of the wire fixing portion 53 a of the control box 5.

The upper end of the fall prevention wire 95 is fixed to the support wire fixing portion 15 of the support 1 by attaching it.
The support wire fixing portion 15 is formed by welding a plate-shaped metal fitting having a through hole to the support 1 in the same manner as the support wire fixing portions 12 and 14. Two are formed.
The fall prevention wire 95 has an upper ring portion 95a attached and fixed to a shackle 71 attached to a through hole of each support wire fixing portion 15.

  When the fixing by the mounting bracket 85 is released, the control box 5 is suspended from the support column 1 by the fall prevention wire 95 having both ends attached to the wire fixing portion 53a and the support wire fixing portion 15 of the support column 1, and Can be prevented from falling off.

  In the control box 5, similarly to the sign body 2, the mounting plate portions 85 b of the mounting bracket 85 are arranged on the left and right sides of the support column 1, and the mounting bolts B <b> 5 inserted through the mounting plate portions 85 b. The mounting bracket 82 is attached to the column 1 by the above. For this reason, if the mounting bolts B5 are not broken or removed from the groove 51 at the same time, the control box 5 removed from the support column 1 moves not in the rear but in the left or right direction including the diagonal direction. The problem that both the fall prevention wires 95 are simultaneously pulled and cut is unlikely to occur, and the fall of the control box 5 can be prevented more reliably.

In addition, the control box 5 that is not fixed by the mounting bracket 85 is easily moved in either the left or right direction including the diagonal direction, not in front of the abutment with the support column 1. For this reason, in the installation structure of the control box 5 in which the support wire fixing portions 15 are formed on both the left and right sides of the support column 1, when the control box 5 moves away from the support column 1, each fall prevention unit that connects the two is provided. Since the wire 95 is less likely to come into contact with articles other than the support column 1, the fall prevention wire 95 is difficult to be cut.
Further, since the support column 1 has a circular cross section and does not have corners, cutting of the fall prevention wire 95 that contacts the outer surface of the support column 1 is suppressed.

In addition, the installation structure of the sign body which concerns on this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.
For example, the wire fixing portion 23a of the marking body 2 is provided by attaching the wire fixing bracket 23 to each groove portion 21 with a mounting bolt B2 in which the bolt head portion is inserted into the groove portion 21 and a nut N2 screwed to the mounting bolt B2. However, it is not limited to this. The wire fixing bracket 23 may be attached to the groove portion 21 by a nut N2 inserted into the groove portion 21 and an attachment bolt B2 screwed to the nut N2. Similarly to the attachment fitting 85 attached to the control box 85, the sign 2 The mounting bracket 82 may be attached to a portion other than the rear groove portion 21 by screwing or welding.

Moreover, although the wire fixing | fixed part 23a of the said label | marker body 2 is provided by attaching the wire fixing metal fitting 23 to each groove part 21 with the attachment volt | bolt B2 and the nut N2 screwed to this, it is not restricted to this.
For example, an eyebolt may be screwed into a nut inserted into the groove 21 and housed, and the ring-shaped head of the eyebolt may be used as a wire fixing portion.
When the eyebolt thus fixed is used as the wire fixing portion 23a, the male screw portion of the eyebolt is directed in the front-rear direction, whereas the head of the eyebolt to which the fall prevention wire-92 is fixed and pulled is substantially upward. A load is applied toward the head.
In other words, when the head is pulled by the fixed fall prevention wire 92, a force that bends in a direction perpendicular to the direction of the screw is applied to the male screw portion of the eyebolt. Furthermore, since the fixing portion between the fall prevention wire 92 and the head of the eyebolt is arranged at a position slightly away from the male screw portion of the eyebolt, a large force is applied to the male screw portion of the eyebolt by the lever principle, and the breakage is broken. There is concern about the possibility of doing.
On the other hand, the wire fixing bracket 23 shown in FIGS. 3 and 4 is fixed to the wire fixing portion 23a because the mounting bolt B2 is inserted and fixed to the through hole of the mounting plate portion 23c formed in a plate shape. When pulled by the fall prevention wire 92, the force in the vertical direction applied to the male screw portion of the mounting bolt B2 is further reduced, and breakage of the male screw portion is suppressed. Further, since the wire fixing bracket 23 is fixed to the marking body 2 by inserting two mounting bolts B2 through the mounting plate portion 23c, the wire fixing portion 23a is pulled to the fall prevention wire 92. When this is done, the force is distributed to the respective mounting bolts B <b> 2, making it difficult to break, and the problem that the wire fixing portion 23 a is detached from the marking body 2 can be suppressed.

The wire fixing portion 23a of the marking body 2 includes a mounting plate portion 23c, a separation portion 23b extending backward from the upper end thereof, and a wire fixing portion 23a extending upward from the rear end thereof. Since it is formed using the metal fitting 23, the wire fixing portion 23 a for fixing the fall prevention wire 92 is arranged at a position separated from the rear surface of the marking body 2. For this reason, when the fixing by the mounting bracket 82 is released and the fall prevention wire 92 is pulled between the marking body 2 and the support 1, the fall prevention wire 92 is less likely to come into contact with the rear surface of the marking body 2. The cutting of the fall prevention wire 92 due to can be suppressed.
Further, when the wire fixing portion 23a is pulled by the fall prevention wire 92, the wire fixing bracket 23 formed by bending a metal plate is deformed so that a bent portion in the vertical direction is opened and the fall prevention is performed. The impact applied from the wire 92 can be reduced, and the problem that the wire fixing portion 23a is detached from the sign body 2 can be suppressed.

  1 to 9, the fall prevention wires 92, 94, 95 are drawn in a straight line so as to be pulled, but the present invention is not limited to this, and the mounting brackets 82, 85, In a state in which the sign body 2, the solar cell unit 4, and the control box 5 are attached to the support column by the shaft attachment portion 41, the sign body 2 may be slightly bent.

  In addition, the sign body 2 shown in FIGS. 1 to 9 is provided so as to perform so-called dot matrix display in which LEDs are arranged in a matrix on the front side and the sign is displayed by combining these lighting and extinction. This is not a limitation. For example, a segment may be formed by a light emitter such as an LED, and so-called segment display may be performed to indicate a sign by light emission of this segment. It may be provided so as to perform display, or may be provided in an external lighting type in which the display portion is illuminated with light from a light emitter disposed on the outside, and the light emitter may not be provided.
