Description

[Detailed Description of the Invention] The present invention relates to a safety device in a mechanical parking facility such as a vertical circulation parking device.

Recently, more and more cars are equipped with door mirrors, and it has even been approved to install door mirrors on domestically produced cars.In this case, the door mirror must protrude approximately 100 to 250 mm on one side from the width of the vehicle body. Since then, there have been concerns that troubles such as mirror damage or contact may occur while driving in a garage, and this has created a need to install detection means as part of safety measures.

Therefore, the present invention provides a safety device that prevents any trouble from occurring by checking the width dimension of the car in the door mirror placed on the cage when the vertical circulation parking system is in operation and turns downward and upward. The gist of this is that several car mounting cages are connected via attachments to an endless link chain that is stretched across a pair of sprocket wheels that are installed vertically on both sides. In a parking device of the type in which the cages are suspended and supported and each of the cages is vertically cyclically driven by rotating the upper sprocket wheel using a suitable drive mechanism, one end is fixed to the cage side of the entrance side bracket. A door mirror detection wire whose other end is elastically attached to the entrance side bracket via a wire sheave and a connection rod on the rear side bracket, and a striker attached to the connection rod to allow movement of the door mirror detection wire. According to the present invention, a wire switch means is provided within the driving rotation range of the cage, and a limit switch installed inside the entrance side bracket, which is turned on and off. Since the wire switch means is disposed facing each other within the upper and lower turning range of the cage on which the door mirror car is placed, if the door mirror car is off-centered with respect to the longitudinal axis of the cage, the wire switch means cannot be detected. When the limit switch comes into contact with the wire, the limit switch is turned off, and thereby the vehicle width dimension is checked and garage operation is stopped, thereby preventing an accident from occurring.

Next, the present invention will be explained in more detail with reference to an embodiment shown in FIGS. 1 to 4.

The vertical circulation parking system, as shown in Figure 1,
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 back side, and several dozen cages are connected through attachments 4 to the endless link chain 3. 5
are suspended at equal intervals, and the upper sprocket wheel is rotated by a drive device 11 consisting of an electric motor 7, a brake 8, a speed reducer 9, a machine stand 10, etc. arranged on a machine base 6,
As a result, each of the cages is configured to be circularly driven in the vertical direction. In this case, a chain guide 12 and a guide roller 13 are installed in the link chain 3 and the cage 5 to prevent them from swinging during driving. It is desirable that the vehicle enters and exits the garage by changing its direction using a turntable 14 provided in front of the entrance.

Furthermore, 15 indicates a control panel base, 16 indicates a take-up frame, and in FIGS. 2 and 3, 17
18 indicates a cage hanger, and 18 indicates a side wall of the garage room 19. The wire switch means 20 in the device of the present invention includes an entrance side bracket 21 whose one end is fixed to both side walls 18, 18 of the garage room 19. A door mirror detection wire 2 is fixed to the side of the cage 5, and the other end is elastically attached to the entrance side bracket via the wire sheave 26 and connection rod 28 of the rear side bracket 22.
3, and a limit switch 24 installed inside the entrance side bracket that is turned on and off by movement of the door mirror detection wire via a striker 27 attached to the connection rod. , door mirror detection wire 2
The inside of 3 is spaced from the cage 5 by, for example, 25 mm, and one end is connected to the entrance side bracket 21 with a stopper 25.
The striker 2
7 is attached to the inlet side bracket 21 via a connecting rod 28 attached thereto and a coil spring 29 directly connected to this. A wire guide fitting 30 is attached to the inner lower surface of the bracket 22.

Therefore, the device of the present invention having the above-mentioned configuration is arranged in the vicinity of the conversion point between the vertical circulation and the turning drive of the cage 5 shown in FIG. It is installed corresponding to the A level and the B-B level which is the conversion end point, and in this case, the wire switch means 20 of the device of the present invention is installed on both side walls 1 of the garage room 19.
Wire switch means 20', 20' of similar construction are installed in a symmetrical arrangement at the intermediate stays 31 and 8, 18, and each component is marked with a "dash" symbol.
They are installed in a symmetrical arrangement.

However, in the embodiment shown in FIG.
One end of the door mirror detection wires 23', 23' of the wire switch means 20', 20' is fixed to the entrance side bracket 21' via wire sheaves 32', 32', and the limit switches 24', 24' are fixed to the intermediate stay 31'. The wire sheaves 26' and 26' are respectively attached to the upper common bracket 33 and the rear bracket 22'.

Thus, according to the device of the present invention, in FIG. 4, after the door mirror car 34 has passed through the cage hanger 17 and entered the garage, the door mirror car 34 placed on the cage 5 when turning downward and upward during garage operation. The door mirror 35 contacts the detection wires 23, 23, 23', 23' of the wire switch means 20, 20, 20', 20' which are set in advance to the regulation width dimension. Garage operation is controlled depending on whether or not there is contact, and in this case, during normal operation, the wire switch means 20, 20, 20', 2
0' (limit switches 24, 24,
24', 24' are in the ON state).On the other hand, if the door mirror wheel 34 is biased to either side with respect to the axis in the longitudinal direction of the cage during vertical turning, the detection wire 23 of the wire switch means, 23,
23', 23', the door mirror 35 contacts or comes into contact with any of the limit switches 24, 24, 24',
24' is turned off, and a well-known control means locks the operation of the parking device, regulating the position of the vehicle in question and preventing an accident from occurring. Further, since the detection by the wire switch means is based on a wire, damage to the vehicle can be prevented.
