In addition, in each figure including FIG. 1, the front side of the vehicle-mounted sign apparatus 10 is indicated as Fr, the rear side as Rr, the right side as R, the left side as L, the upper side as Up, and the lower side as Lo. . The front side refers to the same direction as the traveling direction of the vehicle 1.

As shown in FIG. 1, the vehicle-mounted sign apparatus 10 is installed on the roof 1 a of the vehicle 1.
The vehicle-mounted sign apparatus 10 according to the present embodiment is configured so as to be able to transition between a first state having excellent visibility and a second state having excellent traveling properties, so that visibility can be achieved with a single device. It is possible to achieve both running performance.

FIG. 2A is a side view showing a first state of the vehicle-mounted sign apparatus 10. FIG. 2B is a front view showing a first state of the vehicle-mounted sign apparatus 10. As shown in FIG. 2A and FIG. 2B, the first state is a state where the entire apparatus stands (hereinafter referred to as a standing state).
FIG. 3A is a side view showing a second state of the vehicle-mounted sign apparatus 10. FIG. 3B is a front view showing a second state of the vehicle-mounted sign apparatus 10. As shown in FIGS. 3A and 3B, the second state is a state where the entire apparatus is lying down (hereinafter referred to as a lying state).

First, a specific configuration of the vehicle-mounted sign apparatus 10 will be described with reference to a standing state.
The in-vehicle signing apparatus 10 includes a base 20, a first sign part 30, a second sign part 40, a warning light 50, a drive part 60, an auxiliary part 70, a posture holding part 80, and the like. .
The base 20 is fixed directly or indirectly on the roof 1a of the vehicle 1 and supports the vehicle-mounted sign apparatus 10 as a whole. The base 20 is formed in a rectangular frame shape. As shown in FIG. 2 (a), a side plate 21 protruding upward is coupled to the front side of the base 20 on both the left and right sides. Bearing plates 22 are provided on the side plates 21 on both sides.

The 1st marker part 30 and the 2nd marker part 40 display a sign so that visual recognition is possible with respect to a traffic vehicle behind. In the standing state, the first marker 30 is arranged in parallel on the lower side, and the second marker 40 is arranged in parallel on the upper side.
The first label unit 30 includes a housing 31 and a first display unit 32.
The casing 31 is formed in a box shape whose front-rear dimension is shorter than the left-right dimension and the vertical dimension.
The first display unit 32 is disposed on the rear surface of the casing 31 and displays a sign. A plurality of LEDs are arranged on the first display unit 32 along the top, bottom, left, and right. A sign such as an arbitrary character, figure, symbol or the like can be displayed by a combination of an LED that is turned on and an LED that is turned off. The first display unit 32 of the present embodiment is configured with a vertical / horizontal aspect ratio of approximately 3: 4. The first display unit 32 has a larger display size than the second display unit 42 described later, and therefore has a larger amount of information that can be displayed than the second display unit 42.

A lower plate 33 is coupled to the lower side of the housing 31 on both the left and right sides. The lower plates 33 on both sides protrude toward the lower side beyond the lower end of the housing 31 and overlap the side plates 21 of the base 20 when viewed in a side view. As shown in FIG. 2B, the shafts 34 are fixed to the left and right lower plates 33 across the left and right. The left and right ends of the shaft 34 are pivotally supported by the bearing portion 22 coupled to the side plate 21 of the base 20 described above. Therefore, the first marker 30 can be rotated with respect to the base 20 with the rotation axis O1 of the shaft 34 as the rotation center. That is, the 1st marker part 30 can stand up like FIG. 2 (a), (b), and recumbent like FIG. 3 (a), (b).
An upper plate 35 that protrudes upward is coupled to the upper side of the housing 31 and both left and right sides.

The second label unit 40 includes a housing 41 and a second display unit 42.
The casing 41 is formed in a box shape whose left and right dimensions are longer than the front and rear dimensions and the vertical dimension. Note that the casing 41 has a smaller vertical dimension than the casing 31 of the first marker 30. Specifically, the casing 41 has the same left-right dimension as the casing 31, but the vertical dimension is approximately 1/4.
The second display unit 42 is disposed on the rear surface of the casing 41 and displays a sign. On the second display unit 42, a plurality of LEDs are arranged along the top, bottom, left, and right. A sign such as an arbitrary character, figure, symbol or the like can be displayed by a combination of an LED that is turned on and an LED that is turned off. The second display unit 42 of the present embodiment is configured with a vertical / horizontal aspect ratio of approximately 1: 4. Note that the second display unit 42 has a smaller vertical dimension than the first display unit 32 of the first marker 30. Specifically, the second display unit 42 has the same horizontal dimension as the first display unit 32, but the vertical dimension is approximately 1/3. That is, since the second display unit 42 has a smaller display size than the first display unit 32, the amount of information that can be displayed is smaller than that of the first display unit 32.

On both left and right sides of the housing 41, holding plates 43 are arranged in a state of being spaced from both side surfaces of the housing 41. For example, the holding plate 43 is coupled to the front surface of the housing 41, extends from the front surface of the housing 41 to the left and right sides, and is bent rearward so that a gap is formed between the both sides of the housing 41. It is done. As shown in FIG. 2A, the holding plate 43 partially extends beyond the rear surface of the housing 41 when viewed from the side. The holding plate 43 overlaps the upper plate 35 coupled to the first marker 30 when viewed in side view. That is, the upper plate 35 extends upward from the housing 31 so as to enter between the side surface of the housing 41 and the holding plate 43.
Here, the holding plate 43 is pivotally supported by the upper plate 35 via a shaft (not shown) so as to be rotatable. That is, the second marker part 40 is rotatable with respect to the first marker part 30 about the rotation axis O2. Note that the rotation axis O2 overlaps the second marker 40 when viewed in a side view.

  The warning light 50 emits light such as scattered light to call attention to surrounding traffic vehicles. The warning light 50 is formed with the left and right dimensions of the first marker 30 and the left and right dimensions of the second marker 40 substantially the same. The warning light 50 is coupled to the upper surface of the housing 41 of the second marker 40. Therefore, when the second marker 40 rotates with respect to the first marker 30, the warning light 50 rotates together with the second marker 40.

The drive unit 60 rotates the first marking unit 30 so as to stand upside down from the upside down so as to lie down from the upright side. The drive unit 60 is disposed at a position where it does not interfere with the rotation of the first marker unit 30, here on the left side of the in-vehicle marker device 10.
For example, an electro-hydraulic cylinder is used as the drive unit 60, and a cylinder 61, a rod 62, and a motor 63 are integrally configured. The rod 62 expands and contracts with respect to the cylinder 61 by the rotation of the motor 63 in response to an instruction from the user via an instruction device described later. The end of the cylinder 61 is rotatably connected to the left end of the base 20, and the end of the rod 62 is rotatably connected to the left lower plate 33 of the first marker 30. As the rod 62 extends with respect to the cylinder 61, the first marker 30 stands up as shown in FIG.

The auxiliary unit 70 assists the operation of the first marker 30 that is rotated by the drive unit 60. The auxiliary unit 70 is disposed at a position where the auxiliary unit 70 does not interfere with the rotation of the first marker unit 30, here, on the right side of the vehicle-mounted marker device 10.
For example, a gas spring is used for the auxiliary portion 70, and the auxiliary portion 70 includes a main body portion 71 and a rod 72 as shown in FIG. The end of the main body 71 is pivotally connected to the lower plate 33 on the right side of the first marker 30, and the end of the rod 72 is pivotally connected to the right end of the base 20. The auxiliary unit 70 assists the operation when the driving unit 60 raises the first marker 30 from the lying position, and buffers the operation when the driving unit 60 causes the first marking unit 30 to lie down from the standing position.

The posture holding unit 80 holds the posture of the second marker 40 when the second marker 40 rotates in response to the transition from the standing to the lying and the lying to the standing. .
The posture holding unit 80 uses a connecting member 81 suspended between the base 20 and the second marker 40. As shown in FIG. 2A, the connecting member 81 has a lower end rotatably connected to the side plate 21 of the base 20 and an upper end rotatably connected to the holding plate 43 of the second marker portion 40. . That is, the connecting member 81 can rotate with respect to the base 20 with the rotation axis O3 as the rotation center, and the second marker 40 rotates with respect to the connection member 81 with the rotation axis O4 as the rotation center. It is possible to move. As shown in FIG. 2A, a parallelogram is formed when the rotation axis O1, the rotation axis O2, the rotation axis O4, and the rotation axis O3 are sequentially connected by a straight line. In addition, the connection member 81 is arrange | positioned at both right and left sides, and all are the same structures.

  As shown in FIGS. 2 (a) and 2 (b), when the vehicle-mounted sign apparatus 10 is in a standing state, the first sign part 30 and the second sign part 40 are arranged vertically, and both are integrally formed. The Therefore, by displaying the signs on the first sign part 30 and the second sign part 40, it is possible to improve the visibility with respect to a rear passing vehicle or the like.

Next, the operation in which the vehicle-mounted sign apparatus 10 transitions from the standing state to the lying state will be described.
The rod 62 contracts with respect to the cylinder 61 by the rotation of the motor 63 of the drive unit 60 in response to an instruction from the user via the instruction device. As the rod 62 contracts, the first marker 30 rotates about the rotation axis O1 in the backward direction. In FIG. 2A, the state where the first marker 30 is moved backward is indicated by a two-dot chain line.
Here, the second marker 40 is connected to the first marker 30 via the upper plate 35 and the holding plate 43. Therefore, the second marker 40 also rotates about the rotation axis O1 in conjunction with the rotation of the first marker 30. In addition, the 2nd label | marker part 40 receives force in the direction in which a reverse is regulated by the connection member 81 suspended between the base 20 and the holding | maintenance board 43. As shown in FIG. That is, the in-vehicle signage device 10 is in the upright state and the undulation while the parallelogram connecting the rotation axis O1, the rotation axis O2, the rotation axis O4, and the rotation axis O3 in order by the connecting member 81 is maintained by the connecting member 81. Transition to the state. Therefore, the second marker 40 rotates around the rotation axis O1 while maintaining the posture with the display surface of the second display unit 42 directed rearward. Further, since the warning light 50 is integrally coupled to the second marker 40, the warning light 50 also rotates around the rotation axis O1 while maintaining the posture in the same manner as the second marker 40. Move. Note that, in the relative relationship with the first marker 30, the second marker 40 rotates about the rotation axis O <b> 2 with respect to the first marker 30.

When the rod 62 further contracts, the vehicle-mounted sign apparatus 10 transitions to the lying state.
As shown in FIG. 3A, the first marker 30 lies on the base 20 in a state where it overlaps. At this time, the display surface of the first display unit 32 of the first marker unit 30 faces the base 20 or the roof 1 a of the vehicle 1. On the other hand, the second marker 40 is positioned behind the first marker 30 with the display surface of the second display 42 facing backward, in other words, while maintaining the standing posture. . Similarly, the warning light 50 is positioned on the upper side of the second marking unit 40 while maintaining the posture as in the second marking unit 40. In addition, since the 2nd label | marker part 40 is located in the back side rather than the rear end of the base 20, the 2nd label | marker part 40 is arrange | positioned in the low position which overlaps with the base 20 in the front-back direction.

As shown in FIGS. 3A and 3B, in the lying state of the in-vehicle signing device 10, the first signing unit 30 is lying down. Therefore, since the 1st marker part 30 is suppressed receiving a wind pressure large during driving | running | working, the driveability of the vehicle 1 can be improved. In addition, since the second sign portion 40 transitions to a low position and is visible, it is possible to avoid contact with an obstacle and to display a sign on a rear passing vehicle or the like even while traveling. Can do. In addition, since the second marker 40 is arranged at a position overlapping the base 20 in the front-rear direction, the height of the second marker 40 or the height including the warning light 50 can be reduced. The traveling performance of the vehicle 1 can be improved.
In addition, since the operation | movement which the vehicle-mounted sign apparatus 10 changes from a lying state to a standing state is reverse to the operation | movement which changes from a standing state to a lying state, the description is abbreviate | omitted here.

Next, the indication device of the vehicle-mounted sign apparatus 10 will be described.
