With reference to FIG. 1, problems in recent years in general car stop will be described.
FIG. 1 shows the relationship between the automobile 10, the parking space 23, and the car stop 30. That is, the automobile 10 shows the parking mass 23 as a parking area by displaying the paint 22 on the paved road surface 21 in the parking space 20, and a pair of left and right (left car stop 31) is provided to the end opposite to the entrance to the parking mass 23. , The right car stop 32) is fixed. A vehicle entrance prohibited area (for example, a sidewalk space) 25 is located on the opposite side of the parking space 23 with the car stop 30 as a boundary.
As for the four wheels of the automobile, the right front wheel 11, the right rear wheel 12, the left front wheel 13, and the left rear wheel 14 are used as necessary.

FIG. 1(A) shows a “front stop” for moving the vehicle forward to stop at the car stop 30, and FIG. 1(B) shows a so-called “back stop” for moving the car backward and stopping at the car stop 30.
The spacing between the parking mass 23 and the pair of bollards 30 shown in FIG. 1 is set to match the axle distance of a general automobile. When it is assumed that a large vehicle such as a truck or a bus is parked in the parking space 20, it is common to separately prepare a parking space for the large vehicle or a bollard for the large vehicle. Illustration is omitted here.

Now, as the number of automobiles with automatic transmission increases, the number of accidental start accidents centering on elderly drivers is rapidly increasing. The accidental start accident is that when a vehicle parked in the parking space 23 is started, the vehicle is accidentally started in the direction of the car stop 30, thereby damaging a building in front of the car stop 30 or stopping the car. It is an accident that hits a pedestrian in front of 30. It is caused by the driver's mistake in putting the drive gear and back gear, the mistake on the brake and accelerator, and both of them.

Development of a technology for automating a false start suppression by analyzing a camera image while mounting a camera on an automobile is in progress. However, since it is not a technology that can be retrofitted to an already used car, it is not a fundamental solution.

The techniques disclosed in Patent Documents 1 to 4 described above are not sufficient for suppressing an accident that occurs due to an incorrect start or require a large cost burden.

It is an object of the present invention to provide a technique capable of reducing the extent of an accident even when a stopped vehicle makes a false start.

(First invention)
The first invention relates to a false start detent (50) that separates a vehicle entry prohibited area (25) where the vehicle (10) does not want to enter and a parking area (23) of the vehicle (10) (see FIGS. 2 and 3). reference).
The false start stop (50) is a plate-shaped substrate (51) that contacts the road surface,
A fixing structure (52) for fixing the substrate (51) to the road surface,
A frame-shaped frame (53) fixed upright from the upper surface of the substrate (51),
A rotation restricting body (55) for suppressing the angle formed by the frame (53) with the road surface at a predetermined angle when the frame (53) rotates toward the vehicle entry prohibited area (25),
Equipped with.
When the frame (53) is erected, a part or all of the rotation restricting body (55) is formed within the frame of the frame (53).

(Glossary)
The size of the false start detent (50) is preferably determined according to the size of the vehicle, such as for general vehicles and large vehicles.
The “fixed structure” includes a structure such as fixing to the road surface (see FIG. 5) and fixing to the existing car stop (30) when the existing car stop (30) exists.
Regarding the frame (53), the height at which the upper end of the frame (53) is located when it is erected on the upper surface of the substrate (51) is higher than the height of the current car stop (30). ..
When the rotation restricting body (55) functions to suppress the rotation of the frame (53) when the frame (53) is rotated toward the vehicle entry prohibited area (25), The height at which the upper end is located is higher than the height of the current car stop (about 85 to 120 mm for a normal car and about 200 to 300 mm for a large car).

(Action)
The false start vehicle stop (50) is fixed to a position that separates the vehicle entry prohibition area (25) and the parking area (23) of the vehicle (10). The false start vehicle stop (50) is fixed to the road surface with the board (51) of the false start vehicle stop (50) using the fixing structure (52), and the frame-shaped frame (53) is fixed on the board (51). It stands up from the top. In addition, the rotation restricting body (55) is contained within the frame of the frame when the frame is erected (see FIG. 2). It does not get out of the way as it neither protrudes into the vehicle entry prohibited area (25) nor the vehicle entry prohibited area (25).

If the vehicle (10) parked in the parking area (23) accidentally starts toward the vehicle entry prohibition area (25), the frame (53) contacting the vehicle (10) is moved to the vehicle entry prohibition area. Rotate to the (25) side. However, the rotation restricting body (55) suppresses the angle formed by the frame (53) with the road surface at a predetermined angle. The vehicle (10) that accidentally enters is tilted by being supported by the frame (53) having the predetermined angle. In order to enter the vehicle entry prohibited area (25), it is necessary to climb over the inclined frame (53), so entry into the vehicle entry prohibited area (25) can be almost prevented (Fig. 4(B)). reference).

(Variation 1 of the first invention)
The false start stop according to the first invention may be formed as follows.
That is, the rotation restricting body (55) has its upper portion axially supported by the frame (53). Further, when the frame (53) rotates to the vehicle entry prohibited area (25) side, the frame (53) rotates in a direction opposite to the rotation direction and includes a reverse rotation prevention mechanism that prevents reverse rotation. Of.

(Glossary)
The "reverse rotation preventing mechanism" is, for example, a ratchet mechanism. Although not shown, a gear that rotates at the same time as the rotation shaft, and a gear component that does not hinder the rotation when the gear rotates in the pure rotation direction, and becomes a resistance when reverse rotation is used. The ratchet mechanism consists of.

The rotation restricting body (55) axially supported by the frame (53) is, for example, axially supported near the upper end thereof. In this case, when the frame (53) rotates toward the vehicle entry prohibited area (25), the frame (53) rotates in the opposite direction due to its own weight.

(Action)
When the frame (53) rotates to the vehicle entry prohibited area (25) side, the rotation restricting body (55) rotates in the direction opposite to the rotation direction. Even if the angle formed by the frame (53) and the road surface does not reach the predetermined angle, the rotation restricting body (55) does not rotate in the reverse direction.
For example, even if the acceleration of a vehicle that has started erroneously is too large and the rotation range is finished before the angle formed by the frame (53) and the road surface reaches a predetermined angle, the vehicle does not bounce back and make reverse rotation.

(Variation 2 of the first invention)
The false start detent (50) according to the first invention may be formed as follows.
That is, in the case where the existing bollard (30) is installed in advance at the end of the parking mass according to the wheelbase of the vehicle (10),
The substrate (51) is formed so that the width dimension thereof is smaller than the distance at which the car stop (30) is separated (see FIG. 5).

(Action)
The false start vehicle stop (50) will fit between the existing false start vehicle stop (50). There is originally a dead space between the existing false start vehicle stop (50), and even if the false start vehicle stop (50) is newly fixed, there is almost no need to adjust the existing state in plan view.

(Variation 3 of the first invention)
The false start detent (50) according to the first aspect of the present invention is more preferably formed as follows.
That is, at least the automobile side of the frame (53) is provided with the protector (54) formed of a flexible material.

The “flexible material” is, for example, synthetic rubber or urethane resin.
``At least the car side in the frame (43)'' means that a car that has started wrongly or a car (10) that has tried to stop by exceeding the stop position contacts such a vehicle ( This is because it is possible to prevent the 10) from being scratched, damaged or deformed.

(Variation 4 of the first invention)
The first invention may be preferably formed as follows.
That is, the fixing structure is a rod-shaped body (for example, the embedded rod 42) extended to the opposite side of the substrate (41) from the frame (43).

The “rod-shaped body” is used by being embedded in the road surface (for example, the paved road surface 21). Examples of the material include a columnar shape made of concrete, a round pipe made of steel, and a square pipe. When using a heavy material such as a concrete columnar shape, the embedded dimension (axial dimension) is shorter than when using a light material (for example, a steel pipe).

When the false start vehicle stop (40) according to the present application is installed in an already paved parking lot, installation work is easy.

(Variation 5 of the first invention)
The first aspect of the present invention is more preferable if it is provided with a rotation notification means for notifying when the frame (53) starts rotating with respect to the substrate (51).
The "rotation notification means" is, for example, a sound source and a speaker, or a sound notification means such as a buzzer, a light notification means such as an LED mounted on the frame (43), or a combination thereof (not shown).
It should be noted that it is also possible to make an adjustment such that the rotation notification means is activated only when tilted beyond a predetermined angle.

(Action)
When the frame (53) starts to rotate with respect to the substrate (51) by the driver erroneously starting the parked car, the notification means is activated. The driver is more likely to notice that he/she started the vehicle incorrectly.
When a pedestrian or the like makes a mischief against the accidentally stopped vehicle stop, the notification means operates even if the frame (53) rotates with respect to the board (51), so the notification means also contributes to prevention of tampering. To do.

According to the first aspect of the present invention, it is possible to provide a false start vehicle stop that can reduce the extent of an accident even if a vehicle that does not have a false start suppression function makes a false start.

It is a perspective view showing the present general car stop. It is a perspective view showing the whole false starting vehicle stop concerning the present invention. (A) is a perspective view seen from the parking area side, and (B) is a perspective view seen from the vehicle entry prohibited area side. It is a figure when the false start vehicle stop according to the present invention operates. (A) is a perspective view, (B) is a side view, and (C) is a perspective view seen from below. FIG. 3 is a side view showing the relationship between the false start vehicle stop, the vehicle, and the building on the vehicle entry prohibited area side according to the present invention. (A) shows the state where the vehicle is in the parking area, and (B) shows the state where the false start vehicle stop is activated when the vehicle starts wrongly. It is an assembly perspective view which shows the 1st pattern which fixes the false start vehicle stop which concerns on this invention to a road surface. It is an assembly perspective view which shows the 2nd pattern which fixes the false start vehicle stop which concerns on this invention to a road surface.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The drawings used here are FIGS. 2 to 6. Although FIG. 1 shows the conventional technique, it may be referred to in order to confirm the positional relationship between the parking area 23, the vehicle entry prohibition area 25, and the like.

For convenience of description, a direction “upper, left, right” may be described in the description using the drawings, but the direction does not limit the scope of the patent of the present application.

The false start vehicle stop 50 according to the embodiment of the present invention is located at the boundary between the parking area 23 and the vehicle entry prohibition area 25. Referring to FIG. 1, a paint mark 22 is displayed on the paved road surface 21 to form a parking space 23, and a pair of left and right wheels (a left car stop 31, a right car stop 32) is provided at an end opposite to the entrance of the parking mass 23. It is the false start vehicle stop 50 that installs the vehicle stop 30 that is marked as) at the place where it is already installed.

As shown in FIG. 5, a plate-shaped substrate 41 that fits between the left and right bollards 30, 30 and contacts the paved road surface 21, and a lower surface of the substrate 41 for fixing the substrate 41 to the paved road surface 21. And a buried rod 52 as a pair of fixing structures extending downward from the.
The fixing insertion hole 24 is prepared in advance on the paved road surface 21, and the false start detent 50 is fixed by inserting the embedded rod 52 into the fixing insertion hole 24. Then, in order to ensure the state where the embedded rod 52 is inserted, a fixing liquid such as an adhesive is poured.
The substrate 51 and the embedding rod 52 are often supplied as previously integrated components, but components such as the frame 43 fixed to the upper surface of the substrate 51 are separated from the substrate 51 and the embedding rod 52. In many cases, it is prepared at and installed at the installation site.

On the upper surface of the substrate 51, there is provided a frame-shaped frame 53 which stands upright and is fixed. As shown in FIG. 2B, the frame 53 is provided with two leg frames 53a that are in contact with the upper surface of the substrate 51 and are separated from each other, and extend upward from the ends of the leg frames 53a on the parking area 23 side. Two vertical rod-shaped vertical frames 53c, and an upper frame 53d that is provided between the upper ends of the two vertical frames 53c.

On the other hand, a pipe-shaped frame bearing 51 a is fixed to the upper surface of the substrate 51 on the vehicle entry prohibited area 25 side between the two leg frames 53 a.
A frame shaft 53b penetrating the two leg frames 53a and the frame bearing 51a is fixed to the two leg frames 53a. Therefore, the frame 53 can rotate with respect to the substrate 51 by 90 degrees from the upright state unless the rotation restricting body 55 described later is present.

The rotation restricting body 55 is for suppressing the angle formed by the frame 53 with the road surface at a predetermined angle (angle γ shown in FIG. 3B) when the frame 53 rotates toward the vehicle entry prohibited area 25 side. It is a member of.
Specifically, a rotation-regulating long leg 55a that has a U-shape and the opening side of the U-shape is axially supported by the lower side of the upper frame 53d, and also has a U-shape and the opening side of the U-shape is vertical. The rotation restricting short leg 55c axially supported near the center of the frame 53c in the height direction, the long leg shaft 55b serving as the rotating shaft of the rotation restricting long leg 55a, and the rotation restricting short leg 55c are rotated. It is composed of a short leg shaft 55d which is a moving shaft.

As shown in FIG. 3B, the vertical dimension of the rotation restriction long leg 55a and the rotation restriction short leg 55c is a length for realizing the angle γ formed by the frame 53 with the road surface.
The angle γ is most preferably 20 to 40 degrees. It has been found from experiments and the like that the angle that contributes to stopping the erroneously started vehicle is 15 to 50 degrees. This is because if the angle is less than 15 degrees, it is not sufficient to stop the erroneously started vehicle, and if it exceeds 50 degrees, the angle at which the erroneously started vehicle rotates the erroneous start detent 40 becomes small.

The height h at which the upper end portion of the rotation restriction long leg 55a and the rotation restriction short leg 55c when they rotate until they come into contact with the ground is formed to be higher than the current height of the car stops 31 and 32. This is the minimum condition, but in the case of the false start detent 50 assuming a normal passenger car, it is set to around 1 meter. When the angle γ was 20 to 40 degrees, the height h from the road surface to the upper end of the frame 53 was 600 to 1000 mm.

The rotation restriction long leg 55a and the rotation restriction short leg 55c have the same thickness as the thickness of the frame 53, and when the frame 53 is erected, the rotation restriction is within the frame 53. It is formed so that the whole body 55 can be accommodated. Therefore, when the frame 53 is erected, there is no member that protrudes toward the vehicle entry prohibited area 25 side, and therefore, for example, when a pedestrian walks in the vehicle entry prohibited area 25, the presence of the false start stop 50 may interfere. Don't

When the frame 53 rotates to the vehicle entry prohibited area 25 side, the rotation restricting body 55 rotates in a direction opposite to the rotation direction and has a reverse rotation preventing mechanism that prevents reverse rotation. There is. The "reverse rotation preventing mechanism" is, for example, a ratchet mechanism.

The rotation restriction long leg 55a and the rotation restriction short leg 55c axially supported by the frame 53 are axially supported near the upper ends thereof. In this case, when the frame 53 rotates to the vehicle entry prohibited area 25 side, the rotation restriction long leg 55a and the rotation restriction short leg 55c rotate in opposite directions by their own weight.

Even if the angle formed by the frame 53 and the road surface does not reach the predetermined angle, the rotation restricting body 55 does not rotate in the reverse direction. For example, even if the acceleration of a vehicle that has started erroneously is too large and the rotation range ends before the angle formed by the frame 53 with the road surface reaches a predetermined angle, the vehicle does not bounce back and rotate in the reverse direction. ), it stops at an angle γ.

Protectors 54 made of synthetic rubber are fixed to the left and right vertical frames 53b of the frame 53 on the parking area 23 side. The protector 54 functions to minimize the damage or deformation of the vehicle that has started erroneously.
It comes into contact with the lower end of the bumper of the vehicle that has accidentally started (see FIG. 4(B)), and has a corrugated shape so as to contribute to stopping the vehicle by being caught on the lower end of the bumper.

The upper frame 53d has a vertical dimension larger than the width dimension of the vertical frame 53c. Therefore, the display plate or the like can be fixed.
When the display plate is provided, for example, the display plate is provided with a light emitting component or a buzzer, and when the frame 53 is tilted, light is emitted or the buzzer is operated. As a result, a warning is given to a driver who has started the vehicle 10 by mistake and a person around the vehicle 10.

A solar panel may be fixed to the upper frame 53d. The solar panel serves as a power supply source to an electronic device that operates a buzzer (not shown) or emits light when the frame 53 is tilted, for example.

In FIG. 4, the movement of the false start vehicle stop 50 is continuously shown when the front stopped vehicle 10 starts from the parking space. It is illustrated that the false start vehicle stop 50 exists at the boundary between the parking area 23 and the vehicle entry prohibited area 25, and the store 26 exists on the side opposite to the false start vehicle stop 50 in the vehicle entry prohibited area 25.

FIG. 4(A) shows the vehicle 10 parked while maintaining the clearance with the false start vehicle stop 50. In this figure, the false start vehicle stop 50 is fixed to the vehicle entry prohibited area 25 side of the vehicle stop 30 (not the fixing method shown in FIG. 5).

FIG. 4B shows a state in which the vehicle 10 has accidentally started and collided with the incorrect start vehicle stop 50, and the incorrect start vehicle stop 50 is being rotated. The vehicle 10 that has been accidentally started moves until it occupies the space of the vehicle entry prohibition area 25, and the incorrect start vehicle stop 50 remains until the rotation restriction long leg 55a and the rotation restriction short leg 55c contact the road surface. It is rotating. Since the maximum height h thereof is higher than that of the existing bollard, the front wheels of most of the vehicles 10 are lifted off the road surface, and the vehicles 10 are considerably inclined. Since the driver of the vehicle 10 can feel that he/she got on something in an instant, the driver is more likely to perform an operation such as stepping on the brake pedal.
When the vehicle 10 is driven by the front wheels, there is no further acceleration to move the vehicle 10 at the moment when the front wheels are floated from the road surface.

Although the state between FIGS. 4A and 4B is omitted, the driver of the vehicle 10 should notice the sound of collision with the false start detent 50. In the case where the vehicle 10 is in the automatic state and the driver starts just by releasing the foot from the brake pedal, the driver who notices the collision noise can step on the brake and get good results. Since the vehicle 10 only comes into contact with the protector 45 of the false start stop 50, the vehicle is hardly damaged.

FIG. 6 illustrates an embodiment of a type in which a hole for inserting the insertion rod 52 is provided in the existing car stop 30 and the false start car stop 50 is fixed to the road surface. The false start vehicle stop 50 is larger than the embodiment shown in FIG.

According to the above-described embodiment, the false start vehicle stop 50 can be installed without hindering the existing equipment. In addition, even if an automobile that does not have the false start suppression function makes a false start, it is possible to reduce the extent of an accident and damage to a building or the like.
