JPH1111837A - Intra-car guide device for vehicle elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an intra-car guide device for a vehicle elevator which can prevent breakage of side plates even in case the driver takes a wrong heading by mistake toward the side plate. SOLUTION: Light projecting and receiving apparatuses 7a, 7b, and 7c are furnished to sense the position of a vehicle having intruded into a vehicle elevator car which rises and falls within a shaft and is surrounded by side plates except the gateway, and actuates by a signal from a light receiving apparatus. A guide device issues a guidance to the visual and auditory senses of the vehicle driver that the vehicle has stopped in place or eventually that it has not intruded straight into the elevator car but is advancing toward the side plate.

In the vehicle position detecting device for a vehicle elevator described above, as shown in FIG. 1, when a vehicle driver mistakenly drives in the direction of the side plate, It is installed so that the projector and the light receiver are protected even if the vehicle collides with the side panel and the side panel is broken. In addition, there is no device that issues a danger signal to the vehicle driver when the vehicle moves beyond the position to stop and is about to collide with the rear side plate. There was a danger that an accident that would cause the vehicle to collide with the side or the rear side plate due to being left to his own can and experience.

The present invention has been made in view of such a situation in the prior art, and is intended to be used in the event that a vehicle driver accidentally drives in the direction of the side plate, or at a regular vehicle stop position in front of the rear plate. When the vehicle stops, the infrared rays between the light emitter and the light receiver are shielded, so that a danger signal is generated, and the danger signal indicates that the vehicle driver is likely to collide with the side panel or has reached the stop position. An object of the present invention is to provide an in-car guidance device for a vehicle elevator that guides the user.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to ascend and descend in a hoistway and enter a car of a vehicle elevator for carrying a vehicle surrounded by a side plate except for an entrance. Further, in the car elevator guide device of a vehicle elevator provided with a light emitting device and a light receiving device for detecting the stop position of the vehicle respectively sandwiched between the side surface side plates and provided outside by a first predetermined distance from the side surface side plate surface. This is achieved by providing a structure in which a light emitting device and a light receiving device are provided on the inner side at a second predetermined distance from the surface of the side surface side plate in the same direction as the vehicle traveling direction, and a guide device is provided to alert the vehicle driver. You.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG.
3 will be described.

FIG. 1 is a plan view of the interior of a car of a vehicle elevator equipped with the vehicle position detecting device of the present invention, FIG. 2 is a cross-sectional view of FIG. 1, and FIG. It is explanatory drawing which showed one Embodiment of the guidance content of the guidance apparatus for appealing a danger signal etc. to the visual sense of a vehicle driver when it stopped and the vehicle driver mistakenly advanced driving to the side plate side. . In FIG. 1, the same components as those shown in FIG. 2 are denoted by the same reference numerals. That is,
1 is a car, 2 is a vehicle, 3a, 3b, 4a, 4b are side plates, 5 is a back plate, 6a, 6b, 6c are floodlights, 7
a, 7b, 7c are light receivers, 8a, 8b are protective covers, 9
Is a display for visual guidance, 10 is a speaker for hearing guidance, 11 is a wiring cable, 12 is a control device, 13a, 1
3b and 13c are infrared rays.

[0010] The projector 6a, 6b, 6c and the light receivers 7a, 7b, 7 which are the vehicle position detecting device of this embodiment shown in FIG.
c is sandwiched between the side plates 3a, 3b, 4a, 4b and at a predetermined distance A from the surface of the side plates 3a, 3b, 4a, 4b.
4b, the protective covers 8a, 8b are also installed on the right and left sides of the side plates 3a, 3b, 4a, 4b at a predetermined distance B from the surface in the same direction as the vehicle traveling direction. I have.

In the present embodiment configured as above, the driver of the vehicle 2 entering the car 1 of the vehicle elevator for carrying the vehicle 2 erroneously drives and operates the side wall 3a,
3b, 4a, and 4b, the infrared rays between the light emitter 6b and the light receiver 7b are shielded, and the light receiver is contacted or collided with the side plates 3a, 3b, 4a, and 4b.

Upon receiving the signal, the visual guidance display 9 and the auditory guidance speaker 10 immediately display a message such as "Please straighten the vehicle" or sound as a voice to alert the vehicle driver. Further, when the vehicle 2 reaches the regular stop position, the light emitting device 6a and the light receiving device 7a installed near the rear side plate 5 indicate that the vehicle 2 has reached the vehicle fixed position, as shown in FIG. Since the sentence is displayed on the visual guidance display 9 and the vehicle driver is alerted by the auditory guidance speaker 10, the vehicle 2 may collide with the side panels 3a, 3b, 4a, 4b and the rear panel 5. There is no fear of an accident.

Further, a light projector 6 installed inside at a predetermined distance B from the surface of the side plates 3a, 3b, 4a, 4b.
b, 6c, and the light receivers 7b, 7c, the light emitter 6b is located on the right side and the light receiver 7b is located on the far side when viewed from the entrance, and the light receiver 7c is located on the left side and the light emitter 6c is located on the left side as seen from the entrance. Considering that each infrared ray does not interfere.

[0013]

As described in detail above, in the present invention,
If the vehicle driver accidentally drives in the direction of the side plate, the vehicle will not contact or collide with the side plate, and the side plate will not be destroyed. Further, it is possible to prevent the vehicle from going too far past the normal stop position and causing the vehicle to collide with the rear side plate.
