With reference to FIG. 1, recent problems in a general bollard will be described.
FIG. 1 shows the relationship between the automobile 10, the parking mass 23, and the bollard 30. That is, the automobile 10 displays a parking mass 23 as a parking area by displaying a paint display 22 on the paved road surface 21 in the parking space 20, and a pair of left and right (left bollard 31) to the end opposite to the entrance / exit to the parking mass 23. , The car stop 30 which became the right car stop 32) is fixed. The side opposite to the parking space 23 with the car stop 30 as a boundary is a vehicle entry prohibited area (for example, a sidewalk space) 25.
As for the four wheels of an 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" in which the automobile is advanced and stopped at the bollard 30, and FIG. 1 (B) shows a so-called "rear stop" in which the automobile is moved backward and stopped at the bollard 30.
The distance between the parking mass 23 and the pair of bollards 30 shown in FIG. 1 is sized according to the wheelbase of a general automobile. When it is assumed that a large vehicle such as a truck or a bus will be parked in the parking space 20, it is common to separately prepare a parking mass for the large vehicle and a bollard for the large vehicle. Illustration is omitted here.

By the way, as the number of automatic transmission vehicles increases, the number of accidental start accidents centered on elderly drivers is increasing rapidly. An erroneous start accident is when a car parked in a parking mass 23 is started by mistake in the direction of the bollard 30, thereby damaging the building in front of the bollard 30 or stopping the car. It is an accident that hits a pedestrian who was ahead of 30. It is caused by the driver's mistake in inserting the drive gear and back gear, the mistake in stepping on the brake and accelerator, and even both of them.

Along with mounting a camera on an automobile, the development of technology that automates the suppression of false starts by analyzing the camera image is in progress. However, since it is not a technology that can be retrofitted to automobiles that are already in use, it is not a fundamental solution.

The techniques disclosed in Patent Documents 1 to 4 described above are insufficient for suppressing accidents caused by erroneous starting, or require a large cost burden.

An object of the present invention is to provide a technique capable of reducing the degree of an accident even when a stopped vehicle is erroneously started.

(First invention)
The first invention relates to an erroneous start bollard (50) that separates a vehicle entry prohibited area (25) from which a vehicle (10) does not want to enter and a parking area (23) of the vehicle (10) (FIGS. 2 and 3). reference).
The false start bollard (50) is a plate-shaped substrate (51) that contacts the road surface, and
A fixed structure (52) that fixes 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 when the frame (53) rotates toward the vehicle entry prohibited area (25), and a rotation restricting body (55).
To prepare for.
When the frame (53) is erected, it is formed so that a part or all of the rotation restricting body (55) fits in the frame of the frame (53).

(Glossary)
The size of the erroneous start bollard (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 a road surface (see FIG. 5) and fixing to a bollard (30) when an existing bollard (30) exists.
The minimum dimension of the frame (53) is that the height at which the upper end of the frame (53) is located when it is erected on the upper surface of the board (51) is higher than the height of the current bollard (30). ..
When the rotation restricting body (55) functions to suppress the rotation of the frame (53) when the frame (53) rotates toward the vehicle entry prohibited area (25), the frame (53) The height at which the upper end is located is higher than the height of the current bollard (about 85 to 120 mm for ordinary cars and about 200 to 300 mm for large cars).

(Action)
The false start bollard (50) is fixed at a position that separates the vehicle entry prohibited area (25) and the parking area (23) of the vehicle (10). The false start bollard (50) uses a fixed structure (52) to fix the board (51) of the false start bollard (50) to the road surface, and the frame-shaped frame (53) is of the board (51). It will stand upward from the top surface. 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 protrude into the vehicle entry prohibited area (25) or the vehicle entry prohibited area (25) and does not get in the way.

If the vehicle (10) parked in the parking area (23) accidentally starts toward the vehicle entry prohibited area (25), the frame (53) in contact with the vehicle (10) will be the vehicle entry prohibited area. (25) Rotate to the side. However, the rotation restricting body (55) suppresses the angle formed by the frame (53) with the road surface at a predetermined angle. A vehicle (10) that has entered by mistake will be supported by a frame (53) at a predetermined angle and will tilt. In order to enter the vehicle entry prohibited area (25), it is necessary to get over the tilted 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 erroneous start bollard according to the first invention may be formed as follows.
That is, the rotation restricting body (55) has its upper portion axially supported with respect to the frame (53). When the frame (53) rotates toward the vehicle entry prohibition area (25), the frame (53) rotates in the direction opposite to the rotation direction and is provided with a reverse rotation prevention mechanism for preventing the reverse rotation. It is.

(Glossary)
The "reverse rotation prevention 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 interfere with the rotation of the gear in the pure rotation direction and becomes a resistance when reverse rotation is used. The ratchet mechanism consists of.

The rotation restricting body (55) that is axially supported with respect to 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), it rotates in the opposite direction due to its own weight.

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

(Variation 2 of the first invention)
The false start bollard (50) according to the first invention may be formed as follows.
That is, when the existing bollard (30) is installed at the end of the parking mass in advance according to the wheelbase of the vehicle (10),
The width dimension of the substrate (51) is set to be smaller than the distance between the bollards (30) (see FIG. 5).

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

(Variation 3 of the first invention)
It is more preferable that the false start bollard (50) according to the first invention is formed as follows.
That is, at least on the automobile side of the frame (53), a protector (54) made of a flexible material is provided.

The "flexible material" is, for example, synthetic rubber, urethane resin, or the like.
"At least the car side in the frame (43)" is such a vehicle (10) because it comes into contact with a car that has started erroneously or a car (10) that has tried to stop beyond the stop position. This is because it prevents 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 fixed structure is a rod-shaped body (for example, an embedded rod 42) extending to the side opposite to the frame (43) in the substrate (41).

The "rod-shaped body" is used by embedding it in a road surface (for example, a 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 a heavy material such as a concrete cylinder is used, the embedded dimension (axial dimension) can be shorter than when a light weight material (for example, a steel pipe) is used.

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

(Variation 5 of the first invention)
The first invention is more preferably 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, a voice notification means such as a buzzer, a light notification means such as an LED mounted on a frame (43), or a combination thereof (not shown).
It is also possible to make adjustments such that the rotation notification means operates only when the vehicle is tilted beyond a predetermined angle.

(Action)
When the frame (53) starts to rotate with respect to the board (51) when the driver mistakenly starts the parked car, the notification means is activated. The driver is more likely to notice that he has made a mistake.
In addition, when a pedestrian or the like mischiefs against a false start bollard, the notification means operates even if the frame (53) rotates with respect to the substrate (51), so that the notification means also contributes to prevention of mischief. do.

According to the first invention, it is possible to provide an erroneous start bollard that can reduce the degree of an accident even when a vehicle not equipped with an erroneous start suppression function makes an erroneous start.

It is an assembly perspective view which shows the 2nd pattern which fixes the erroneous start bollard 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 prior art, it may be referred to in order to confirm the positional relationship between the parking area 23, the vehicle entry prohibited area 25, and the like.

For convenience of explanation, the direction of "up / down / left / right" may be described in the description using drawings, but that direction does not limit the scope of the claims of the present application.

The erroneous start bollard 50 according to the embodiment of the present invention is located at the boundary between the parking area 23 and the vehicle entry prohibited area 25. Explaining with reference to FIG. 1, a paint display 22 is displayed on the paved road surface 21 to make a parking mass 23, and a pair of left and right (left bollard 31, right bollard 32) to the end opposite to the entrance / exit to the parking mass 23. This is an erroneous start bollard 50 that installs the bollard 30 that has become) in the place where it has already been installed.

As shown in FIG. 5, a plate-shaped substrate 41 that fits between the left and right bollards 30 and 30 and is in contact with the paved road surface 21 and a lower surface of the substrate 41 for fixing the substrate 41 to the paved road surface 21. It is provided with a pair of burial rods 52 as a fixed structure extending downward from the sill.
A fixing insertion hole 24 is prepared in advance on the paved road surface 21, and the erroneous start bollard 50 is fixed by inserting the buried rod 52 into the fixing insertion hole 24. Then, in order to ensure that the buried rod 52 is inserted, a liquid to be fixed such as an adhesive is poured.
The substrate 51 and the buried rod 52 are often supplied as integrated parts in advance, but the parts such as the frame 43 fixed to the upper surface of the substrate 51 are separated from the substrate 51 and the embedded rod 52. It is often prepared at the installation site and pumped up at the installation site.

The upper surface of the substrate 51 is provided with a frame-shaped frame 53 that is fixed upright in the upward direction. As shown in FIG. 2B, the frame 53 extends upward from two leg frames 53a that are in contact with and separated from the upper surface of the substrate 51 and an end portion of the leg frame 53a on the parking area 23 side. It includes two square bar-shaped vertical frames 53c and an upper frame 53d passed between the upper ends of the two vertical frames 53c.

On the other hand, a pipe-shaped frame bearing 51a is fixed to the upper surface of the substrate 51 on the vehicle entry prohibition area 25 side between the two leg frames 53a.
Then, the two leg frames 53a and the frame shaft 53b penetrating the frame bearing 51a are fixed to the two leg frames 53a. Therefore, the frame 53 can rotate 90 degrees with respect to the substrate 51 from the standing state if the rotation restricting body 55 described later does not exist.

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 prohibition area 25. It is a member of.
Specifically, the rotation-restricted long legs 55a, which have a U-shape and the opening side of the U-shape is axially supported by the lower side of the upper frame 53d, also have a U-shape and the opening side of the U-shape is vertical. The rotation-restricted short leg 55c that is axially supported near the center of the frame 53c in the height direction, the long leg shaft 55b that is the rotation axis of the rotation-restricted long leg 55a, and the rotation-restricted short leg 55c. It is composed of a short leg shaft 55d, which is a driving axis.

As shown in FIG. 3B, the vertical dimensions of the rotation-restricted long legs 55a and the rotation-restricted short legs 55c are lengths for realizing the angle γ formed by the frame 53 with the road surface.
The angle γ is most preferably 20 to 40 degrees. Experiments have shown that the angle that contributes to stopping a car that has started erroneously is 15 to 50 degrees. This is because if it is less than 15 degrees, it is not enough to stop the erroneously started vehicle, and if it exceeds 50 degrees, the angle at which the erroneously started vehicle turns the erroneously started bollard 40 becomes small.

The height h at which the upper end portion is located when the rotation-restricted long legs 55a and the rotation-restricted short legs 55c are rotated until they touch the ground is formed to be higher than the heights of the current bollards 31 and 32. This is the minimum condition, but in the case of an erroneous start bollard 50 assuming an ordinary 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 thickness of the rotation-restricted long legs 55a and the rotation-restricted short legs 55c is the same as the thickness of the frame 53, and when the frame 53 is erected, the rotation is restricted within the frame of the frame 53. It is formed so that the entire body 55 fits. Therefore, when the frame 53 is erected, there is no member protruding toward the vehicle entry prohibited area 25, and therefore, for example, when a pedestrian walks in the vehicle entry prohibited area 25, the existence of the erroneous start stop 50 is hindered. Must not be.

When the frame 53 rotates toward the vehicle entry prohibition area 25, the rotation restricting body 55 is provided with a reverse rotation prevention mechanism that rotates in the direction opposite to the rotation direction and prevents the reverse rotation. There is. The "reverse rotation prevention mechanism" is, for example, a ratchet mechanism.

The rotation-restricted long legs 55a and the rotation-restricted short legs 55c that are axially supported with respect to the frame 53 are axially supported near the upper ends thereof. In this case, when the frame 53 rotates toward the vehicle entry prohibition area 25, the rotation-restricted long legs 55a and the rotation-restricted short legs 55c rotate in the opposite directions due to their own weight.

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

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

The upper frame 53d has a vertical dimension larger than the width dimension in the vertical frame 53c. Therefore, it is possible to fix the display plate or the like.
When a display plate is provided, for example, a light emitting component or a buzzer is provided on the display plate so that light is emitted or the buzzer is activated when the frame 53 is tilted. As a result, it is a warning to the driver who misstarted the vehicle 10 and the people around the vehicle 10.

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

FIG. 4 continuously shows the movement of the erroneously started bollard 50 when the front bollard 10 starts from the parked mass. It is shown that the erroneous start bollard 50 exists at the boundary between the parking area 23 and the vehicle entry prohibited area 25, and the store 26 exists on the opposite side of the erroneous start bollard 50 in the vehicle entry prohibited area 25.

FIG. 4A shows a vehicle 10 parked while maintaining a clearance with the erroneous start bollard 50. In this figure, the erroneous start bollard 50 is fixed to the vehicle entry prohibition area 25 side rather than the bollard 30 (not the fixing method shown in FIG. 5).

FIG. 4B shows a state in which the vehicle 10 erroneously starts and collides with the erroneous start bollard 50, and the erroneous start bollard 50 is rotated. The vehicle 10 that has been erroneously started moves until it occupies the space in the vehicle entry prohibited area 25, and the erroneous start bollard 50 is until the rotation-restricted long legs 55a and the rotation-restricted short legs 55c come into contact with the road surface. It is rotating. Since the maximum height h is higher than that of the existing bollard, most of the vehicles 10 have the front wheels floating from the road surface, and the vehicle 10 is in a considerably tilted state. As a driver of the vehicle 10, since he / she can instantly feel that he / she has climbed on something, there is a high possibility that he / she will step on the brake pedal.
When the vehicle 10 is front-wheel drive, there is no further acceleration to move the vehicle 10 at the moment when the front wheels are in a state of floating from the road surface.

Although the state between FIGS. 4A and 4B is not shown, the driver of the vehicle 10 should notice the sound of collision with the erroneous start bollard 50. In the case where the vehicle 10 is automatic, if the driver just takes his foot off the brake pedal and starts the vehicle, the driver who notices the collision sound steps on the brake and gains nothing. Since the vehicle 10 only comes into contact with the protector 45 of the false start bollard 50, the vehicle is hardly damaged.

FIG. 6 illustrates an embodiment of a type in which a hole into which an insertion rod 52 can be inserted is provided in an existing bollard 30 and the false start bollard 50 is fixed to the road surface. The erroneous start bollard 50 is larger than the embodiment shown in FIG.

According to the above-described embodiment, the erroneous start bollard 50 can be installed without interfering with the existing equipment. In addition, even if a vehicle not equipped with a false start suppression function makes a false start, it is possible to reduce the degree of accident and damage to buildings and the like.

The present invention has potential in the manufacturing industry of parking lot equipment, the service industry involved in the installation and operation of parking lots, and the like.
