Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a device for preventing a car door from being left ajar in a multi-story parking facility, which is equipped with a mechanism for detecting the ajar state of a car entered in a moving cage. It is.

(Prior art) Conventional examples of the multi-level parking facility are shown in Figures 1 to 3.
To explain with a diagram, a large number of cages 1 are suspended on an endless chain that moves vertically in a multi-story parking lot, and a car A is placed inside the cage 1 waiting at a car entrance floor. After getting in,
The chain moves the cage 1 containing the car a vertically to enter and park the car, and conversely, the cage 1 containing the car a is lowered to the car entry floor A and stopped. The structure is such that the car inside the cage 1 is taken out to the outside, and when the car a enters the cage 1 at the car entry floor A, the ajar door of the car a entered into the cage 1 is opened. In order to prevent this, an automatic door ajar prevention fence 2 is provided on the side of the cage 1, which automatically stands up from the outside using a spring bias. When the door b is half-open, the half-open door prevention fence 2 may hit the lower side of the door b and its automatic raising is stopped, and if the cage is raised via the chain in this state, the half-open door b There is a risk of contact with equipment 3, etc., resulting in a serious accident.

In addition, as a measure to prevent doors from opening ajar as described above, a phototube is installed on the floor, and a reflector that receives and reflects the light emitted from the phototube is placed at the bottom of the outer surface of the self-supporting fence to prevent doors from opening ajar. An automobile door ajar prevention device has been proposed which is provided with a shielding plate that blocks reflected light emitted from a reflecting mirror and disables a cage drive device when the door of an automobile is ajar.

(Problems to be Solved by the Invention) The conventional automobile door ajar prevention device detects the ajar door of the automobile and disables the cage drive device to prevent accidents caused by the ajar door. After getting out of the car without noticing the door, the driver will detect that the door is ajar because the cage drive device is not working, and the door will be released ajar, resulting in wasted hand washing and printing time.
The reflector is placed at the bottom of the outer surface of the half-door prevention fence, making it difficult to ensure a large reflection range, that is, a detection range.Therefore, it is also necessary to place the phototube on the floor, making it difficult to secure installation space. At the same time, there are problems such as the complexity of the accompanying equipment.

(Means for Solving the Problems) The present invention is an invention to solve the above-mentioned drawbacks of the conventional car door ajar prevention device for multilevel parking facilities, and involves applying a spring bias to the side of the cage being moved. A reflective member is provided on the upper part of the outer surface of the door ajar prevention fence which is attached so that it can be automatically erected. The mechanism is characterized by an ajar door detection/display mechanism in which a photoelectric switch is installed opposite to the wall side of a multi-story parking structure, and a door ajar indicator operated by the photoelectric switch is disposed. An object of the present invention is to provide an automobile door ajar prevention device for a multilevel parking facility that eliminates the above-mentioned drawbacks by preventing a car from entering the garage with an ajar door by providing a mechanism for detecting the upright state of an ajar prevention fence when the door is ajar. be.

(Function) The present invention has the above-mentioned configuration, and when a car enters the cage waiting at the car entry position,
A door ajar prevention fence attached to the side of the cage is automatically erected by spring bias, eliminating the door ajar state of the car, and a reflection installed on the upper outer surface of the erect door ajar prevention fence automatically stands up. The reflected light emitted from the member is detected by a photoelectric switch, and if the door is ajar, the photoelectric switch activates the door ajar indicator to display the door ajar, so the driver can immediately detect the door ajar and turn the door ajar. The door will be removed.

In addition, the reflective member is installed on the upper part of the outer surface of the door ajar prevention fence to ensure a sufficient reflection range, that is, the confirmation range for ajar doors, and a photoelectric switch is installed opposite to the wall side of the multi-story parking structure to prevent doors ajar. Detection performance and operational reliability have been improved.

(Example) Figures 4 to 6 show an example of the present invention, and 1 in the figure shows a large number of chains suspended from an endless chain disposed within a multi-story parking structure and moved vertically. Cages, 2, on the side of each cage 1,
A half-door prevention fence pivoted at the lower side so as to automatically stand up from the outside by spring bias; 3 is, for example, a drive control device for a chain; After the car a enters the car, the cage 1 in which the car a is entered is vertically moved by the chain to enter and park the car, and conversely, the cage 1 in which the car a is parked is moved to the car entrance floor. In addition, in this embodiment, there is also a half-mounted car attached to the side of each cage 1. A reflective member 5 such as a reflective plate or reflective tape is fixedly provided on the upper outer surface of the door prevention fence 2, and the reflective member 5 is installed on the door ajar prevention fence 2 that stands up in the cage 1 waiting at the car entry floor position. A photoelectric switch 6 for detecting reflected light emitted from 5,
It is fixedly installed on the side of the wall 10 on the side of the multi-story parking structure and is placed opposite to the reflective member 5, and the reflective member 5 and the photoelectric switch 6 are connected to the half-door indicator such as an indicator lamp (not shown). It is configured with a door ajar detection/display mechanism that displays.

The illustrated embodiment has the above-described configuration, so that when a car a enters the cage 1 waiting at the car entry floor a, the door ajar prevention fence 2 attached to the side of the cage 1 is automatically erected by the spring bias, the ajar door of the car a is eliminated, and the reflected light emitted from the reflective member 5 provided on the upper part of the outer surface of the erect door ajar prevention fence 2 is reflected by the photoelectric switch 6. When the door is detected, the display is activated and the door ajar is displayed, so the driver can immediately detect the ajar door of the car and release the ajar door. The photoelectric switch 6 cannot perform the above-mentioned detection even when the moving angle is large and the door ajar detection range is sufficiently large, and the door ajar prevention fence 2 is not sufficiently erected due to the widely opened door b. This makes it possible to detect whether a door is ajar, detect an abnormal state of the vehicle a being entered, and eliminate the abnormal state before moving, eliminating erroneous operations and preventing accidents from occurring.
It is also possible to install alarm equipment to issue an alarm if necessary. In the above embodiment, the case where the car entrance floor A was provided at the lowest part was explained, but depending on the surrounding environment of the multi-story parking structure, it is possible to provide it in the middle of the structure. Similarly, the entry position can also be provided at a different position from the vehicle entry position.

(Effects of the invention) The present invention has the above-mentioned configuration, and a reflective member is provided on the upper part of the outer surface of the half door prevention fence that can be automatically erected by spring bias, and a photoelectric sensor is installed on the wall side of the multi-story parking structure. In addition to the opposite switch, there is also a door ajar indicator activated by a photoelectric switch, which ensures a sufficiently large door ajar detection range and allows the driver to immediately detect when a car's door is ajar. The present invention has advantages such as excellent door ajar detection performance and reliability, and easy and proper door ajar detection.The mechanism is simplified and operational reliability is achieved.
