[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic plan view showing a first embodiment of the present invention. In the drawing, reference numeral 1 denotes a parking lot, for example, a plurality of N parking areas A having contours 2 formed by paint.
_1, A ₂ ...... A _N are formed in parallel.

Here, each of the parking areas A _{1 to} A _N is:
The size of the vehicle is set to have a predetermined margin from the size of the largest vehicle assumed to be parked. This margin is at least on the side of the vehicle, for example, when the vehicle is parked in the adjacent parking areas A _i and A _{i + 1} , when the door of one vehicle is opened at the time of getting on and off, the tip of this door is The size is selected so that it does not touch the vehicle.

On the opposite side of each of the parking areas A _{1 to} A _{N from} the vehicle entrance side, the center axis in the left-right direction of the vehicle 3 having the largest size assuming parking is indicated by the parking areas A _{1 to} A. The guide lights 5L and 5R as a pair of left and right guide light emitting means are located at positions where parallel light beams can be emitted to the door mirrors 4L and 4R as left and right side mirrors of the vehicle when the center line coincides with the center line in the vehicle width direction of _N. Are arranged.

As shown in FIGS. 2 and 3, each of these guide lights 5L and 5R has a pair of front and rear light sources 7A and 7B coaxially superimposed on the upper end of a column 6 fixed vertically to the ground. It is arranged in a state.

The light source 7A includes a reflector 8 formed in a large-diameter hollow bowl shape (parabolic shape in cross section) fixed to a support 6, and a red visible light beam disposed in the reflector 8, for example. And a light source body 9 composed of a light-emitting bulb.

Here, the reflector 8 has its opening surface directed in the vehicle approaching direction, and its central axis is on the ground and in the parking areas A _{1 to} A _1.
The light source body 9 is arranged so as to be parallel to the side edge in the vehicle width direction of _N , and reflects a light beam emitted from the light source main body 9 and emits it as a visible light beam having a circular cross section in the vehicle approach direction.

The light source 7B has a reflector 10 smaller in diameter than the reflector 8 fixed to the L-shaped support piece 6a formed on the support column 6, and a green visible light, for example, provided in the reflector 10. And a light source body 11 composed of a light bulb that emits light.

Here, the reflector 10 is arranged coaxially with the reflector 8 so as to fall within the parallel visible light emitted from the light source 7A. Next, the operation of the first embodiment will be described with reference to FIGS.

If it is assumed that the vehicle 3 is to be parked in the empty parking area _Aj in the parking lot 1 while, for example, the right-hand drive vehicle 3 is retracted, the vehicle 3 is first retracted while turning the steering wheel largely so that the rear wheel side is parked. _Aj is made to enter Aj while turning so as not to block parallel rays from the guide light 5R.

[0022] In this turning state, the traveling direction of the vehicle approaches a parallel to the side edge of the parking area A _j, door mirrors 4R
Is irradiated with parallel rays from the guide light 5R,
This is reflected to the driver's line of sight, so that the driver can visually recognize the parallel rays from the guide light 5.

At this time, since the parallel light from the guide light 5 is a coaxial light whose central portion is a green parallel visible light from the light source 7B and its surrounding is a red parallel visible light from the light source 7A, FIG. As shown in FIG. 5, when the vehicle 3 is retreating in parallel with the coaxial ray from the guide light 5R, the coaxial ray reflected by the door mirror 4R maintains the coaxial state as shown in FIG. By being reflected to the driver side,
When the driver is looking door mirror 4R, rays caught on this, as shown in FIG. 4 (b), becomes a concentric superimposed state, the driver entry angle proper state to the parking area A _j of the vehicle Can be recognized.

However, as shown in FIG. 6 (a), when the approach angle of the vehicle is such that the center axis of the vehicle is on the rear side of the vehicle,
When it is shifted in a counterclockwise direction such that it intersects with the optical axis of the coaxial ray from R, as shown in FIG.
Since the angle of R rotates counterclockwise from the state shown in FIG. 5, the reflected light reflected by the door mirror 4R toward the driver becomes thinner on the left side of red light on the outer peripheral side and thicker on the right side. As shown in FIG. 6B, the light beam reflected on the door mirror 4R is in a state where the optical axis of the outer red light is shifted to the right, the approach angle of the vehicle is shifted in the clockwise direction, and the right steering is performed. You can recognize that it is necessary.

[0025] Then, by right steer the vehicle in this state, it is possible to return to the state of FIG. 4 (b), by retracting while maintaining this state, proper vehicle parking area A _j The vehicle can be accurately stopped at the position.

In the case where the approach angle of the vehicle is deviated in the direction opposite to the direction shown in FIG. 6A with respect to the normal rectilinear retreat state, the optical axis of the outer red light reflected on the door mirror 4R is deviated to the left. It is possible to reliably recognize that the driver is in a state where the driver needs to turn left.

Further, even if the vehicle is moved backward so that the light of the left guide light 5L is irradiated on the left door mirror 4L,
By visually recognizing the optical axis shifts of the light sources 7A and 7B in the same manner as described above, the approach angle of the vehicle can be properly maintained.

As described above, according to the first embodiment, the vehicle is moved backward so as to irradiate the door mirror 4L or 4R with the superimposed light beam of the guide light 5L or 5R. It is possible to immediately judge whether or not there is, and even a driver who is inexperienced in maneuvering the vehicle can easily stop the vehicle at an appropriate parking position, especially when the illumination of the parking lot is dark at night etc. In such a case, the vehicle can be easily stopped at an appropriate parking position.

As a result, it is possible to reliably prevent two parking areas from being occupied or from causing a collision accident with a vehicle parked in an adjacent parking area during parking.

Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the guide lights 5L and 5R constituting the guide light emitting means are vertically long so that vehicles having different vehicle heights can be easily recognized.

In the second embodiment, the light source 7A fixed on the support column 6 of each of the guide lights 5L and 5R constituting the guide light emitting means, as shown in FIG. 8, is viewed from the approach direction of the vehicle. Reflector 21 having a relatively wide and vertically elongated rectangle extending in the vertical direction and having a parabolic cross section.
And a neon tube 22 as a light source body that emits, for example, red light, which is disposed on the inner side of the reflector 21 with the axial direction as a vertical direction. Are emitted toward the door mirrors 4L and 4R of the approaching vehicle.

The light source 7B also has a vertically elongated rectangular shape with a width shorter than the width of the reflector 21 of the light source 7A, and has a parabolic cross section. For example, a neon tube 24 as a light source body that emits green light is disposed in a vertical direction, and a green parallel visible light having a rectangular cross section that is substantially vertically elongated from an opening surface of the reflector 23 is a door mirror 4L of an entering vehicle. , 4R.

And, these light sources 7A and 7B
Similarly to the embodiment, when the light source 7B is disposed in the red parallel visible light at a position in front of the light source 7A, and viewed with the door mirrors 4L and 4R in a vehicle having a normal approach angle,
As shown in FIG. 9, the light source 7A is disposed in the center of the inside of the red parallel visible light so that the green parallel visible light of the light source 7B appears in a striped pattern.

[0034] Also with this second embodiment, by advancing the vehicle 3 in the parking area A _j, when parallel rays of guide lights 5L or 5R is a state to be irradiated on the door mirror 4L or 4R, driver door mirror When looking at the vehicle, when the vehicle is entering normally, the green visible light is located just in the center of the red parallel visible light, and it can be recognized that the vehicle is in the normal approach state. When the approach angle of the vehicle changes from the state, the green visible light moves from the center in the left and right direction accordingly,
It is recognized that a deviation occurs in the approach angle and that correction by steering is necessary.

At this time, since the cross-sectional shape of the parallel light emitted from the parking guide light is a vertically long rectangular shape, even if the vehicle height of the door mirrors 4L, 4R is different from the vehicle type, the pack mirrors 4L, 4R are reliably irradiated. It is possible to perform more reliable guidance.

In each of the above embodiments, the light source 7
A case where the red visible light and the green visible light are emitted in A and 7B has been described. However, the present invention is not limited to this, and any visible light of any color can be applied as long as the visible light can recognize a difference in color. In particular, the light source 7B only needs to be able to form a shadow with respect to the light emitted from the light source 7A, so that the light emitted from the light source 7A may be simply shielded without emitting any special light. When point light sources are used as in the first embodiment, they may be provided in a plurality of stages at predetermined intervals in the vertical direction. In this case, even vehicles having different vehicle heights can be reliably viewed. There are advantages that can be done.

Further, in each of the above embodiments, the case where the color parallel visible light is directly emitted from the guide lights 5L and 5R has been described. However, the present invention is not limited to this. A reflector having a front shape equal to the shape of each of the guide lights as viewed from the front is disposed, and the reflector reflects light from a light source provided on the ground side to irradiate the door mirrors 4L and 4R. Further, a half mirror may be provided on the ground side to distribute light rays from one light source to a plurality of parking areas. In this case, the number of light sources can be reduced, so that equipment cost is reduced. Can be reduced.

Further, in each of the above embodiments, the vehicle having the door mirrors 4L and 4R has been described. However, the same effect can be obtained in a vehicle having a fender mirror as a side mirror.

Further, in each of the above embodiments,
The case where the present invention is applied to the parking area of the parking lot has been described. However, the present invention is not limited to this. The present invention can also be applied to a parking area formed on the road, and in this case, the sidewalk of the parking area It is preferable to provide the guide light emitting means only on the side so as not to hinder the traffic of the vehicle.

[0040]

As described above, according to the parking guidance device of the first aspect, the guidance light emitting means has a configuration in which a pair of light sources that emit visible light of different colors is superposed and arranged.
Since the emitted light of the guide light emitting means is applied to the side mirror of the vehicle that normally enters the parking area, when the driver looks at the side mirror, a pair of the mirrors changes according to a change in the angle of approach of the vehicle. Since the superposition state of the light beam changes,
It is possible to accurately recognize the approach angle of the vehicle, and to obtain an effect that it is possible to accurately park the vehicle in the parking area when the driver is inexperienced in driving or when the parking area is difficult to visually recognize at night.

According to the parking guidance device of the second aspect, the guidance light emitting means coaxially superimposes the color-parallel visible rays having circular cross sections having different diameters. In the state parallel to the visible light, it is visually recognized as a double concentric circle, but when the approach angle crosses the color parallel visible light, the central axes of the two color circles are shifted, so that the approach angle differs. The effect of being able to easily recognize is obtained.

Further, according to the parking guidance device of the third aspect, since the pair of light sources in the guidance light emitting means has a rectangular section that is long in the vertical direction, the vehicle height is different and the height of the side mirror above the ground is reduced. The driver can easily visually recognize the guide light emitting means even in different cases, and the effect that parking guidance of vehicles of different types of vehicles can be accurately performed can be obtained.

Further, according to the parking guidance device of the fourth aspect, since the visible color light from the light source is reflected by the reflector, the parallel light beam is directed toward the side mirror of the vehicle with a simple configuration. The effect that light can be emitted is obtained.
