Description

[Detailed Description of the Invention] The present invention relates to a safety device for a mechanical parking facility that checks in advance for vehicles that are outside the specified dimensions and prevents such vehicles from entering the parking lot.

In conventional mechanical parking equipment, most of the detection means for the width direction of the car (door ajar, vehicle width) rely on rising fences and fixed beams of photoelectric devices, which has the disadvantage that the detection range is narrow. In addition, recently, more and more cars are installing door mirrors, and they have even been approved for installation on domestic cars.
Since the mirror protrudes by approximately 100 to 250 mm, there are concerns that problems such as damage to the mirror may occur while driving in the garage, and this has created a need to install detection means as part of safety measures.

Therefore, the present invention attempts to provide a safety device for mechanical parking equipment that can solve the above-mentioned problems. The plastic detection chains wrapped around each hoisting device have limited vehicle width dimensions, and the movable magnets are stored in a case attached to the lower ends of both chains by suspending them by coil springs. However, a fixed magnet and a micro switch are mounted on brackets installed at both ends of the floor surface on the entry/exit side so as to be located on the same vertical axis as the movable magnet,
Thus, according to the present invention, it is possible to check at the entrance or the boarding area for cars whose door mirrors protrude beyond the vehicle width limit when entering the garage, and prevent such cars from entering the garage, thereby preventing troubles. Of course, it is also possible to restrict the width of vehicles other than cars.

Next, the present invention will be explained in more detail with reference to an embodiment shown in FIGS. 1 to 5.

In FIG. 1, 1 is an entrance or boarding area of a car 3 to which a door mirror 2 is attached, 4 is a tray or trolley on which the car is placed, 5 is a hoisting device such as a winch, and 6 is a plastic detection chain. In the ceiling 7 of the entrance or boarding area 1, oppositely arranged hoisting devices 5, 5 are installed facing each other, and the drums of the hoisting devices have a structure that is well known in the art. The detection chains 6, 6 are wrapped around and suspended via chain guides 8, 8. In this case, both chains are held within the regulated vehicle width dimension and are mounted in cases 10, 10 attached to the lower end. The movable magnets 9, 9 are connected to the coil springs 11, 1.
1 and is stored in a hanging manner.
In addition, as shown in FIG. 2, brackets 13,
13 are installed, and these brackets are equipped with fixed magnets 14, 14 and a micro switch 1.
5 and 15 are mounted on the same vertical axis as the movable magnets 9 and 9, when the movable magnets 9 and the fixed magnets 14 and 14 are attracted by magnetic force, they are centered and the micro switch 15 is , 15 are turned on and removed, the microswitch is turned off.

Thus, to describe the operating mode of the device of the present invention having the above-mentioned configuration, the hoisting devices 5, 5 are activated in advance by operating a drive mechanism (not shown).
When the detection chains 6, 6 are lowered by driving the detection chains 6, 6, the movable magnets 9, 9 attached to the lower ends of the chains are attracted to the fixed magnets 14, 14 on the brackets 13, 13 installed on the floor 12. The microswitches 15, 15 are turned on as a result of centering (see FIG. 3). With this state set, as shown in FIG.
When the driver gets on the vehicle, when the door mirrors 2, 2 come into contact with the detection chains 6, 6, which are set to the regulated vehicle width, the movable magnets 9, 9 move away from the fixed magnets 14, 14, so that the micro switch 15, 15 is in the off state, thereby locking the operation of the parking device by means of a control means known per se and preventing the entry of vehicles 3 other than the specified dimensions, while, of course, contacting the sensing chains 6, 6. Vehicles 3 that pass without colliding with each other
is stored in the warehouse, and when leaving the warehouse, the hoisting devices 5, 5 are driven as shown in FIG. 5, and the detection chains 6,
6 is rolled up to a position where there is no problem in taking out the warehouse, for example, to the lower end of the chain guides 8, 8, and taken out of the warehouse.
