Description

[Detailed description of the invention] (Industrial application field) This invention connects several dozen automobiles via attachments to an endless link chain stretched between a pair of sprocket wheels provided at the top and bottom of both sides. This invention relates to a safety device for a parking device of the type in which a mounting cage is suspended and supported, and the cage is vertically cyclically driven by rotating the upper sprocket wheel using a suitable drive mechanism.

(Prior Art) As a safety measure for the above-mentioned type of vertical circulation parking device, in an emergency, the operator presses an emergency push button built into the control panel installed in front of the entrance to stop the device operation suddenly. It's becoming like that.

(Problem to be Solved by the Invention) However, in the above-mentioned parking device, when the driver is walking along the cage-side passage in order to store or take out the car in or out of the cage, the operator If the equipment is operated incorrectly, there is a risk of personal injury.

Therefore, the present invention aims to provide a safety device that prevents personal accidents by using a detection body installed in the passageway for occupants such as driver workers.

(Means for Solving the Problems) Therefore, according to the present invention, a sideways detection rod is movably provided in the walking path of the room occupant, and when the body of the room occupant touches the detection rod, the detection rod is moved. A tape switch is provided that comes into contact with the tape switch and stops the electric motor for operating the device when it is displaced.

(Example) The vertical circulation parking device shown in Fig. 1 is
Two endless bands, for example, an endless link chain 3, are connected to two pairs of opposing upper and lower sprocket wheels 1 and 2 on the entrance side and the back side, and several tens of automobiles are connected through an attachment 4 to the endless link chain 3. The storage cage 5 is suspended, and the upper sprocket wheel is rotated by a drive device 11 consisting of a conductor 7, a brake 8, a speed reducer 9, a machine stand 10, etc., which are arranged on a machine base 6. Therefore, each of the cages is configured to be circularly driven in the vertical direction, and in this case, a chain guide 12 and a guide roller 13 may be installed in the link chain 3 and the cage 5 to prevent them from swinging during the circularly driving. Preferably, the vehicle enters and exits the garage by changing direction using a turntable 15 provided in front of the entrance 14.

In the configuration described above, the safety device according to the present invention is installed on either side (on the right side in the figure) of the left and right passages 18 of the movable fence 17 of the door ajar prevention device 16 attached to the storage cage 5. Mainly, the front and back brackets 2 are installed oppositely on the front wall 20 and rear wall 21 of the building 19.
2, 23 and the long grooves 24, 25 drilled in both brackets shown in FIG.
Tape switch 26 that operates with a contact pressure of several tens of grams,
27 and a detection rod 28 that slides loosely into the long groove. In this case, support recesses 30 and 31 for the detection rod are formed below the long groove. The tape switch is not attached to these support recesses,
Therefore, although the device is not operated in this state, when a part of the driver's body or an object comes into contact with it, the detection rod moves up and down or left and right and comes into contact with the tape switch. is activated to stop driving the electric motor 7.

(Function) For example, when a driver loads a car into the storage cage 5 for parking and gets off the cage, the door ajar prevention device 16, which had been lying down,
The movable fence 17 stands up and the cage side passage 18
If the operator accidentally presses the start button while walking, the device will start operating, so it is natural for the driver to feel in danger and take immediate shelter action. A part of the tape switch 28 touches the detection rod 28 of the detection body 29, and the detection rod moves left and right or up and down, and the tape switch 2
6 and 27, the tape switch is actuated and the drive of the electric motor 7 is stopped, thereby causing an emergency stop of the device operation.

In the above embodiment, a vertical circulation type parking device has been described, but the present invention is not limited to such a parking device, but can also be applied to other types of parking devices, such as multilayer circulation type, horizontal circulation type, etc. Of course, the present invention is applicable, and the same purpose can be achieved by combining a detection lever and a limit switch as detection objects.

(Effects of the invention) From the above, according to the invention, a sideways detection rod is displaceably provided in the walking path of the room occupant, and the detection rod is displaced when the body of the room occupant touches the detection rod. When a person enters the parking device, we installed a tape switch that comes into contact with the tape switch and stops the motor for operating the device.
If the driver accidentally drives the vehicle when he or she should not be driving, the parking device is immediately stopped without any special action by the person entering the vehicle, thereby preventing accidents resulting in injury or death.

Claims (1)

[Scope of utility model registration request] Several dozen car mounting cages are suspended and supported via attachments on endless link chains stretched between a pair of sprocket wheels provided at the upper and lower portions of both sides, and the upper sprocket wheels are connected to the upper sprocket by an appropriate drive mechanism. In a parking device of the type in which the cage is vertically circulated by rotating a wheel, a horizontal detection rod is movably disposed in the walking path of the occupant, and the body of the occupant touches the detection rod. 1. A safety device for a vertical circulation type parking device, characterized in that a tape switch is provided which comes into contact with the detection rod and stops an electric motor for operating the device when the detection rod is displaced.
