Description

  The present invention relates to a foldable guidance display device used as a guide sign or a danger sign during road construction or a traffic accident.

  In the event of road construction or traffic accidents, there are cases where guidance indicators such as arrow display boards indicating the direction of travel must be installed on the road for the purpose of traffic control. Most of the guidance display tools used at this time are portable because of their usage, and are carried on work vehicles and patrol cars.

  As these portable guidance indicators, for example, there is a plastic triangular cone (cone). The plastic triangular conical cylinder is lightweight but has a large volume, so that the number of plastic triangular conical cylinders is limited when loaded on a work vehicle or a patrol car. In addition, when long distance regulation is performed in multiple lanes or one lane, the necessary number is insufficient and it is not possible to respond quickly enough. In addition, there is a drawback that the wind falls and blows away and the stability is poor.

  In order to solve the above-mentioned disadvantages of the cone, there is a guidance display device in which two plates are connected so as to be foldable, and when used, the two plates are opened and installed on the ground (for example, Patent Documents). 1)

  The display panel 10a is obtained by printing a marker 12 with a fluorescent paint on the front surface of a panel body 11 formed of a thick plate made of synthetic resin (see FIG. 2). The front surface of the panel body 11 is an irregular reflection surface. The irregular reflection surface is formed by an aluminum foil having fine irregularities formed on the surface thereof, which is coated with a transparent coating, or a transparent paint in which metal powder is mixed. In FIG. 1, the traveling direction of the vehicle is indicated by an arrow as the sign 12, but characters such as “stop” and “slow down” may be printed according to the purpose of traffic control.

  A light emitting member 13 in which a plurality of LEDs (light emitting diodes) are linearly arranged is provided on the edge of the sign 12. Although not shown, a cavity through which the cord for the light emitting member 13 passes is formed inside the panel body 11. As shown in FIG. 3, a battery case 14 is attached to the rear surface (back surface) of the display panel 10 a, and the light emitting member 13 and the battery case 14 are connected by a cord wired in the hollow portion of the panel body 11. Yes.

  The battery case 14 houses a dry battery as a power source for the light emitting member 13. The battery case 14 is provided with a light emitting member switch 15 and an operation check lamp 16. When the light emitting member 13 is caused to emit light, the switch 15 of the battery case 14 is turned on and the operating state is confirmed by the lamp 16.

  At night, the irregular reflection surface and the fluorescent paint formed on the surface of the panel main body 11 reflect the light of the vehicle headlight well so that the driver and passengers can clearly see the sign 12. Furthermore, the visibility of the sign 12 is further enhanced by causing the light emitting member 13 to emit light or blink.

  Since the configuration of the display panel 10b is the same as the configuration of the display panel 10a, description thereof is omitted. By displaying the traveling direction of the vehicle with the sign 12 on the display panel 10a and the sign 12 on the display panel 10b, the vehicle driver can more clearly confirm the traveling direction. As shown in FIG. 1, the light emitting member 13 of the display panel 10b and the battery case 14 of the display panel 10a are coupled by a cord 17 through a through hole provided in the frame on the center side of the frames 20a and 20b. .

  The display panels 10a and 10b are attached to the frames 20a and 20b, respectively. The frame body 20a is made of an aluminum pipe made of an upper horizontal frame 21, a lower horizontal frame 22, a left vertical frame 23, and a right vertical frame 24, which are rectangular with synthetic resin (polycarbonate) coupling members 25, 26, 27, and 28. It is fixed as follows.

  The frames 21 to 24 are made of an aluminum pipe having a square cross section, and a slit 29 is formed inside the pipe. The display panel 10a is attached to the frame 20a by inserting linear protrusions formed on the side surfaces of the synthetic resin panel body 11 into the slits 29.

  Although not shown, the coupling members 25 to 28 have projections formed in directions orthogonal to each other. After the projections are inserted into the opening ends of the frames 21 to 24, they are fixed to the frames 21 to 24 by screws or caulking. . In the present embodiment, the coupling members 25 to 28 are fixed to the frames 21 to 24 by caulking the aluminum frames 21 to 24.

  In addition, as a method of fixing the coupling members 25 to 28 to the frames 21 to 24, there is a method of using screws other than the method by caulking. If it is necessary to disassemble the frame after it is assembled, a method using screws is preferred. On the other hand, in the case where the frame body is not disassembled after assembly, the caulking method is preferable from the viewpoint of cost.

  The configuration of the frame body 20b is the same as the configuration of the frame body 20a except that it is bilaterally symmetric, and a description thereof will be omitted.

  A guide member 30 is disposed between the frame bodies 20a and 20b so as to sandwich them. The guide member 30 is U-shaped, and a linear upper arm 31 and lower arm 32 are attached to both ends of the guide body 33 (see FIG. 5). An auxiliary arm 34 is attached to the front ends of the upper arm 31 and the lower arm 32 in order to increase the strength of the guide member 30. Further, a handle 35 for carrying is attached to the front portion of the auxiliary arm 34. The guide member 30 is made of steel having a square cross section.

  As shown in FIG. 2, the coupling member 25 of the frame body 20a and the coupling member 25 of the frame body 20b are connected to the guide member 30 in a movable and rotatable state by a slide member 40 located in the middle. Yes. Similarly, the coupling member 26 of the frame body 20a and the coupling member 26 of the frame body 20b are connected in a movable and rotatable state by a slide member 50 located in the middle.

  The slide member 40 is provided with hinge portions 42 and 43 at both ends of a slide main body 41 disposed so as to straddle the upper arm 31 of the guide member 30. 12 is a front surface).

  Similarly, the slide member 50 is provided with hinge portions 52 and 53 at both ends of a slide main body 51 disposed so as to straddle the lower arm 32 of the guide member 30, and is anteroposterior in a state orthogonal to the lower arm 32. It is configured to be slidable in the way.

  A hole is formed in the hinge portion 42 of the slide member 40, and a rotation shaft (not shown) attached to the upper surface of the coupling member 25 of the frame body 20a is inserted into the hole. Similarly, a hole is formed in the hinge portion 43 of the slide member 40, and a rotation shaft (not shown) attached to the upper surface of the coupling member 25 of the frame body 20b is inserted into the hole.

  The configurations of the hinges 52 and 53 provided at both ends of the slide member 50 are the same as the configurations of the hinge portions 42 and 43 of the slide member 40 except that they are upside down, and the description thereof is omitted. .

  As shown in FIG. 4, the upper horizontal frame 21 of the frame 20 a and the upper arm 31 of the guide member 30 are connected by a link member 61. The link member 61 is attached to a middle portion of the upper horizontal frame 21 by a pin so as to be capable of turning, and the link member 61 is attached to a front portion of the upper arm 31 by a pin so as to be capable of turning.

  Similarly, the upper horizontal frame 21 of the frame body 20 b and the upper arm 31 of the guide member 30 are connected by a link member 62. The link member 62 is attached to a middle part of the upper horizontal frame 21 by a pin so as to be able to turn, and the link member 62 is attached to the front part of the upper arm 31 so as to be able to turn by a pin.

  Similarly to the upper horizontal frame 21, the lower horizontal frame 22 of the frame body 20 a and the frame body 20 b is connected to the lower arm 32 of the guide member 30 by the link members 63 and 64. In addition, hem processing is given to the single side | surface of each link member 61-64 in order to raise an intensity | strength.

  Next, the function of the guidance display tool 1 will be described. Since the display panels 10a and 10b of the guidance display tool 1 are attached to aluminum frames 20a and 20b made of relatively light and strong aluminum, they have sufficient strength as a guidance display tool.

  As shown in FIG. 4, the center of gravity of the guidance display 1 is on the guide member 30 on the rear side of the frames 20a and 20b when the display is in use. As a result, the guide indicator 1 is supported at the three points of the coupling member 28 of the frame body 20a, the coupling member 28 of the frame body 20b, and the lower end 32 of the lower arm 32 of the guide member 30, so Installed in a stable state. Moreover, since the frame bodies 20a and 20b arranged on the same straight line and the guide member 30 are arranged in a state of being orthogonal to each other, the structure is difficult to fall over even if wind blows.

  Further, since the insides of the frames 20a and 20b are not entirely covered with the display panels 10a and 10b and a gap is provided in part, the wind hitting the display panels 10a and 10b escapes through the gap. As a result, the wind pressure applied to the display panels 10a and 10b can be reduced and the pressure caused by the wind can be reduced.

<Procedure for folding and opening the guide display>
Next, a description will be given of a procedure for folding the frames 20a and 20b for transportation from a state in which the guidance display tool 1 shown in FIG. 1 is installed on the road, and a procedure for opening again for installation.

  As shown in FIG. 4, the frame body 20 a is connected to the guide member 30 through the slide members 40 and 50 so as to be movable. The frame body 20a is connected to the guide member 30 through link members 61 and 63 in a rotatable state. Similarly, the frame body 20b is connected to the guide member 30 through the slide members 40 and 50 in a movable state. The frame 20b is connected to the guide member 30 through link members 62 and 64 in a rotatable state.

  Therefore, when both ends of the frames 20a and 20b are rotated forward (downward in the drawing in the drawing) as shown by the arrow A from the state in which the frames 20a and 20b are opened to the left and right, as shown by the two-dot chain line. In addition, the slide members 40 and 50 move backward (in the direction indicated by the arrow B) along the guide member 30, and the frame bodies 20 a and 20 b rotate in a direction approaching the guide member 30.

  Subsequently, when the frame bodies 20a and 20b are rotated in the direction of arrow A, the frame bodies 20a and 20 are folded into a state shown in FIG. That is, the frame bodies 20a and 20b are overlapped on the upper and lower sides of the guide member 30, and the thickness of the guidance display tool 1 becomes very thin.

  When transporting the guidance display 1, after the folded state as shown in FIG. 6, the operator holds the handle 35 and carries the guidance display 1 to a work vehicle or patrol car, and lies horizontally in the storage space. If they are stacked in the same state, the space can be used effectively.

  When the guidance display 1 is installed on the road, an operation opposite to the above operation may be performed. That is, the operator carries the handle 35 of the guidance display 1 in a folded state as shown in FIG. Next, when the operator grasps the guide body 33 of the guide member 30 with one hand and pushes out the vertical frame 24 of the frame bodies 20a and 20b forward (in the direction opposite to the arrow B in FIG. 4) with the other hand, The usage state shown in FIG. 1 can be set. Thus, since it can transfer to a use state from the folded state by simple operation, the installation of the guidance display tool 1 on a road can be performed rapidly.

  In this embodiment, the link members 61 and 62 are attached to the upper parts of the frame bodies 20a and 20b, and the link members 63 and 64 are attached to the lower parts of the frame bodies 20a and 20b. May be attached. When the link member is attached to only one of the upper and lower sides, the strength of the display device is slightly weakened, but there is no problem in the function as the guidance display device.

  Further, with respect to the hinge portions 42 and 43 of the slide member 40 and the hinge portions 52 and 53 of the slide member 50, the rotation shafts are attached to the coupling members 25 and 26, but conversely, the hinge portions 42, 43, 52 and 53 are attached to the hinge portions 42, 43, 52 and 53. A similar function can be realized by attaching a rotation shaft and providing a hole for inserting the rotation shaft in the coupling members 25 and 26.
