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 detecting the width direction (door ajar, vehicle width) or height of a car are based on a rising fence of a photoelectric device, a fixed photoelectric beam, etc., so the detection range is narrow. Recently, more and more cars are installing door mirrors, and they have even been approved for installation on domestic cars.
Since the protrusion is approximately 1 mm, there is a need to ensure safety by installing 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. A swing mechanism consisting of a swing shaft having the swing gear fixedly attached to one end thereof and a pair of swing arms integrally attached to both sides of the swing shaft is mutually interlocked in the pit. A detecting member or a detecting means for checking the width or height of the vehicle is attached to the swing mechanism, and when the swing arm of the swing mechanism is in the middle of rotation due to the operation of the swing drive mechanism, When width or height conflicts, swing arm rotation and parking device operation are locked, and when the swing arm does not conflict with both dimensions, the return switch is operated to reverse and return to the previous position. Thus, according to the present invention, during the rotation of the swing arm in a swing mechanism mainly consisting of a swing arm and the detection member or detection means attached thereto, the detection member or detection means When the swing arm hits or comes into contact with a target object, such as a door mirror or a door that is ajar, the rotation of the swing arm and the operation of the parking device are locked by means of a control means that is well known in the art. This has the effect of preventing accidents from occurring by preventing cars from entering the warehouse.

Next, the present invention will be explained in more detail with reference to two embodiments shown in FIGS. 1 to 8.

In FIGS. 1 and 2 showing a first embodiment of the present invention, 1 is a car, 2 is a tray or a trolley, 3 is a detection member for checking the width or height of the car 1, and 4 is a swing drive mechanism. , 5 is a swing mechanism, 6 is a door mirror, a detection switch 7 having a limit switch function and a detection wire 18 to be described later are used as the detection member 3, and the swing drive mechanism 4 is a drive installed in the pit 8. Motor 9 and swing gear 1 directly connected to it
0 and a swing mechanism 5.

is set to the solid line position shown in FIG. 2, and when the car 1 is placed on the tray or trolley 2 for storage, if the drive motor 9 of the swing drive mechanism 4 is appropriately rotated in the forward direction, the swing gear 10 will rotate. As a result, the swing shaft 13 rotates, and both of the swing arms, which are integral with the swing shaft 13, rotate in the direction of the hour hand. In this case, the car 1 that has passed without the detection wire 18 stretched inside the swing arms 14 and 15 coming into contact with the door mirror 6 (vehicle width) and the car height can be stored, and therefore the next A return operation cam 1 attached to the swing shaft 13 for checking incoming cars.
7 turns on the return switch 16 to reversely rotate the drive motor 9, and the swing arms 14 and 15 rotate in the counterclockwise direction via the swing drive mechanism 4 and the swing mechanism 5, and move from the two-dot chain line position to the solid line. It will be returned to the old position shown in .

On the other hand, the detection wire 18 is connected to the door mirror 6 (vehicle width)
Or when it comes into contact with any part of the vehicle height, the detection wire is pulled in the direction of arrow A shown in FIG. 1, so the detection switch 7 of the detection member 3 is turned on.
As a result, the rotation of the swing arms 14 and 15 and the operation of the parking device are locked by means of a well-known control means, thereby preventing cars 1 other than the specified size from entering the parking lot, and then the drive motor 9 is caused to rotate in the reverse direction. If so, the swing arms 14 and 15 are reversed via the swing drive mechanism 4 and the swing mechanism 5 and returned to their old positions.

Next, FIGS. 3 and 4 show that, whereas in the embodiment described above, the swing arms 14 and 15 are rotated on both sides of the door mirror 6 or the driver for checking or detection, a vehicle with a similar configuration is This shows an embodiment of the first embodiment according to the present invention for checking or detecting the vehicle height and longitudinal length of the first vehicle.
The same parts as in the figures and FIG. 2 are given the same reference numerals.

In this embodiment, the swing drive mechanism 4 and the swing mechanism 5 are installed on either the left or right side in the longitudinal direction of the tray or the trolley 2, and the swing arms 14 and 15 of the swing mechanism 5 are arranged as shown in FIG. As shown in the figure, the vehicle 1 is rotated from the solid line position to the two-dot chain line position and returned to its original position, and the height and longitudinal length of the vehicle 1 are determined by a detection wire 18 stretched inside both swing arms. The progress of each operation is shown in Figures 1 and 2.
The details are the same as those of the embodiment shown in the figures, so the explanation will be omitted.
