Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle position warning device for notifying a driver of the stopped position of a vehicle body.

Conventional Technology A device such as the one disclosed in Utility Model Application No. 111138/1983 has been devised as a vehicle position warning device that informs the driver of the exact location of the vehicle when reversing the vehicle in a parking lot, etc. There is.

As shown in FIG. 13, this vehicle position warning device is composed of a plate-shaped riding part 1 and a semi-cylindrical warning device main body 2. Then, the weight of the car acts on the riding part 1, which prevents the alarm body 2 from moving. In this vehicle position alarm device, similarly to a general vehicle position alarm device in which a rectangular parallelepiped block is simply installed, the vehicle reaches a predetermined position when the tire 3 comes into contact with the alarm device main body 2. The driver is made aware of the impact.

Problems to be Solved by the Invention However, in the case of conventional vehicle position warning devices, the shock generated when the tires 3 come into contact with the warning device main body 2 notifies the driver that the vehicle has reached a predetermined position. Because
There is a problem in that the driver cannot accurately inform the driver of the vehicle's position because the driver may run onto the alarm device main body 2, mistaking it for a stone or object that has fallen on the ground.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a vehicle position warning device that can accurately and reliably notify a driver of the position of a vehicle.

Means for Solving the Problems The present invention, as a means for solving two problems,
In a vehicle position alarm device that informs the driver of the vehicle position by coming into contact with the vehicle, the main body of the alarm device is formed of a hollow elastic body, and the sound is generated by air entering and exiting the main body of the alarm device as it is elastically deformed. A sounding body that emits a sound is provided.

When the tires of the operating vehicle come into contact with the alarm body, the alarm body is elastically deformed, air enters and exits, and the sounding body emits a sound.

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 12.

First, the first embodiment will be explained. In this embodiment, a mode will be shown in which the vehicle position warning device according to the present invention is employed in a car stop that notifies the driver that the vehicle has stopped at a predetermined position when reversing the vehicle in a parking lot.

In FIGS. 1 to 3, numeral 11 is the part on which the tire 3 of the vehicle that is retreating first runs over, and numeral 12 is the part where the tire 3 rides on.
This is the main body of the alarm that the outer peripheral surface of the alarm comes into contact with. The riding part 11 is formed into a plate shape from metal or hard synthetic resin, and the alarm main body 12 is formed into a hollow shape from an elastic body such as synthetic rubber or synthetic resin. This alarm main body 12 has a first
, a substantially triangular hollow cross section as shown in FIG. 2, or a semicircular hollow cross section as shown in FIG. 3. The riding part 11 and the alarm main body 12 are integrated by adhesive bonding, welding, integral molding, or the like.

A whistle 14 is provided on the side wall of the alarm main body 12 as a sounding body that emits a sound when air enters and exits. When the alarm main body 12 is elastically deformed, the internal air blows to the outside from the whistle 14. It is designed to emit a sound when it is released. 15 in the figure is a reinforcing rib integrally formed inside the alarm main body 12.

In a parking lot where this vehicle position alarm device is installed on the ground, when a car is backing up, the tire 3 of the car runs over the part 11.
After riding on the alarm device, its outer peripheral surface comes into contact with the alarm device main body 12. Then, the alarm main body 12 is elastically deformed, the air inside is blown out from the whistle 14 portion, and the whistle 14 emits a sound. At this time, the driver feels the impact caused by the tire 3 coming into contact with the alarm main body 12 and at the same time hears the sound of the whistle 14, so that the driver can reliably know that the vehicle has stopped at a predetermined position.

Next, a second embodiment of the present invention will be described.

In this embodiment, a mode will be shown in which the vehicle position alarm device according to the present invention is employed in a garage or the like.

In FIGS. 4 to 7, reference numeral 22 denotes a hollow alarm main body made of an elastic body similar to that of the above-mentioned embodiment. , a reinforcing rib 15 is provided inside. In the case of this embodiment, unlike the first embodiment, the alarm main body 22 is not integrally provided with a riding part.

In addition, the vehicle position alarm device of this embodiment is not installed directly on the ground, but is installed on a wall surface of a garage or the like as shown in FIG.
0, 31, 32, etc., the flat surface 22a of the alarm device main body 22 is bonded.

Because of this configuration, if a car enters the garage as shown in Figure 7 and is about to come into contact with the rear or side walls 30, 31, 32, the car will stop before it comes into contact with the wall 30, etc. When the whistle 14 comes into contact with the alarm main body 22, the whistle 14 emits a sound. Therefore, the driver can know that he has approached the wall 30 or the like. Moreover, since the alarm main body 22 is formed of an elastic body, the car does not come into direct contact with the wall surface 30 or the like, but is cushioned by the elastic body, thereby preventing scratches or damage.

Next, a third embodiment of the present invention will be described. In this embodiment, the vehicle position warning device according to the present invention is installed on a road where construction work is being carried out, and the vehicle position warning device notifies the driver that the vehicle has entered the area ahead of the installation location. A mode in which this is done will be shown.

In Fig. 8.9, 42 is a semi-cylindrical alarm main body made of an elastic material such as synthetic rubber or synthetic resin, and this alarm main body 42 has a whistle 14 as a sounding body on its end surface. At the same time, a rib 43 is provided at the bottom extending in the longitudinal direction and protruding toward the inside of the hollow portion. This rib 43 is provided when a vehicle tire passes over the upper part of the alarm main body 42 and the alarm main body 42 is elastically deformed.
This is provided so that the alarm main body 42 can immediately return to its original shape and be ready for the passage of the next tire. Furthermore, a recess 44 and a protrusion 45 for joining are formed at both ends of the alarm device body 42, and a plurality of vehicle position alarm devices can be joined in the longitudinal direction by fitting the recess 44 and the protrusion 45. ing.

The concave portion 44 and the convex portion 45 have a dovetail structure,
Even if the vehicle position alarm devices are pulled in the longitudinal direction in the fitted state, they will not separate from each other. In addition, 46 is a reinforcing material for protecting the whistle 14 provided inside the end portion of the alarm main body 42.

Because of this configuration, if a predetermined number of vehicle position alarm devices are connected in the longitudinal direction and installed on a road where construction work is being carried out, the tires of the vehicle traveling on the vehicle will be activated by one of the vehicle position alarm devices. When the alarm device body 42 passes over the device, the alarm device main body 42 whose upper part the tire has passed is elastically deformed, and the whistle 14 emits a sound due to the air being blown out at that time. For this reason,
The driver of the vehicle can know the vehicle position (that the vehicle has entered the no-entry zone) by the slight impact when passing the alarm main body 42 and the sound of the whistle 14.

Note that the embodiments of the present invention are not limited to these; for example, as shown in FIG. It is also possible to have a structure that can prevent the installation position of the vehicle position alarm device from shifting due to deformation of the main body 42 in a direction other than the vertical direction, and as shown in FIG. It is also possible to have a structure in which the parts 47 can be freely engaged and disengaged so that they can be easily carried.

Effects of the Invention As described above, in the present invention, the main body of the alarm device is formed of a hollow elastic body, and the main body of the alarm device is provided with a sounding body that emits sound by the inflow and outflow of air accompanying the elastic deformation of the main body.
The position of the vehicle can be accurately and reliably informed to the driver by the secondary blow and the sound of the sounding body when the vehicle contacts the alarm body.
