Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanical parking device, particularly a vertical circulation parking device, in which a turntable is incorporated into a cage in which a car is placed.

Conventionally, as the above-mentioned type of vertical circulation parking device, a rotating circulation parking device as disclosed in Japanese Utility Model Publication No. 52-48551 has been proposed, but this device has the following drawbacks. .

(1) By lifting the base plate, the side circumferential surface of the tapered friction driven wheel provided on the upper surface of the plywood is brought into contact with the circumferential surface of the tapered friction driven wheel provided on the lower surface of the rotating floor. Since the floor is rotated, the relative positions of the driven wheels and the driving wheels in the radial direction must always be accurate, which makes manufacturing and construction difficult.

That is, if the center positions of the driven wheel and the driving wheel are too far apart, they will not make contact, and if they are too close, the driving wheel will push the driven wheel in the opposite direction at the point of contact, and the opposite will occur. The force becomes a braking force and is applied to the driven wheels, which not only makes it impossible to drive easily with a small horsepower motor, but also requires the shaft of the drive vehicle to be made stronger to counteract this force.

(2) When the driven wheel and the driving vehicle come into contact, the relative positions of the two must be accurate, so turning or rotating operations are performed only after the swinging car storage cage has stopped accurately at the predetermined position. Otherwise, it cannot be performed, and therefore it takes time to operate.

In contrast, the present invention aims to provide a vertical circulation parking system that can eliminate the above-mentioned drawbacks, and its gist is that a power cylinder is installed in a pit corresponding to the lowest position of the cage. and a cage clamp device comprising a crankshaft interlocked with the crankshaft and cage clamp rollers attached to both sides of the crankshaft, and a geared motor and a pair of bevel gears to be disposed coaxially therewith. Equipped with a friction roller rotating mechanism consisting of a gear box on which the friction roller is installed so that it can be raised and lowered, and a friction roller raising and lowering mechanism consisting of a power cylinder and a compressed coil spring between both fork ends that are to be arranged coaxially with the power cylinder. A turntable rotation drive device is provided, and when the friction roller is raised and raised by the raising and lowering mechanism, the friction roller elastically presses against the inner circumferential surface of the circular rail, and in this state, the rotation mechanism The present invention resides in that the turntable is configured to be rotated under the cage support of the clamp roller by friction transmission force, and thus,
According to the present invention, the friction roller buttoned on the turntable rotation drive device is elastically pressed against the inner surface of the circular rail integrally formed on the back surface of the turntable. Even if the circular rail is slightly deviated in the radial direction, there is no risk of non-contact or over-contact phenomena, which makes manufacturing and installation easy, and even if the car storage cage swings and descends, the cage clamp will not work. It is held in that position by the clamp roller of the device, and in this state, even if the relative position in the radial direction between the friction roller and the circular rail deviates somewhat, the friction roller presses against the inner periphery of the circular rail. Swivel or rotation does not require much effort, and this makes it possible to reduce the weight of the cage and turntable and to make the entire device more compact and simple without impairing its functionality, and therefore, it is possible to significantly reduce manufacturing costs. This makes it possible to provide a parking device that is reasonably priced.

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

2° 22 and these swing levers are integrated in a direction perpendicular to the storage cage 1 with a lower connecting rod 23° 24 and an upper connecting rod 25 pivotally connected in the longitudinal direction of the cage.
, 26 to form a parallelogram link, in which case both said lower connecting rods are pivoted on a platen (27, 28) mounted on the back side of the cage member 6, By the operation of the conversion drive device, the movable fence 19 is rotated counterclockwise in FIG. 1 and clockwise in FIG. 4.

The conversion drive device 20 is mainly composed of a suppressing rod 29 and a pusher 30, and the tip 31 of the pressing rod is positioned so as to face the head 32 of the pusher. When the head moves in the direction of arrow A in FIGS. 1, 3, and 4, the suppression rod 29 is pushed and the crank connected to the rond end and attached to one end of the lower connecting rod 23 is pressed. Since the arm 33 rotates clockwise in FIG. 4, the swing levers 21 and 22 also move in unison from the solid line position to the two-dot chain line position, and therefore the movable fence 19 moves from the upright position (operating position) to the collapsed position ( When the Ronde is released from the depression, the tension coil spring 34 provided between the side part of the cage member 6 and the lower part of the swing lever 21 is activated. Accordingly, the movable fence is automatically returned to the operating position (erected position).

Further, the turntable rotation drive device 4 includes a friction roller raising/lowering mechanism 35 and a friction roller rotation mechanism 36 interlocked with this, as shown in FIGS. 1 and 3.
The raising and lowering mechanism is comprised of a power cylinder 37 to be installed on the pit bottom surface (not shown) formed corresponding to the lowest position of the storage cage 1, and a power cylinder coaxially arranged therewith. The rotation mechanism consists of a side fork end 38° compression coil spring 39 and a gear box side fork end 40, and the rotating mechanism consists of a gear motor 41 to be installed on the bottom of the pit, a coupling 42 coaxially arranged therewith, and a gear box 43. In this case, the raising/lowering mechanism and the rotating mechanism include an operating arm 44 whose one end is welded to the gear box 43 and whose other end is pivotally connected to the gear box side fork end 40.
The gearbox is driven by l.
A pair of bevel gears 45 and 46 are installed internally, and the drive side bevel gear 45 is mounted on the end of a drive shaft 48 that is supported by a bearing 47 and directly connected to the geared motor 41 via a coupling 42. .

Further, a driven bevel gear 46 that meshes with the driving bevel gear 45 is supported by a driven shaft 49 that is bearing within the gear box 43 and protrudes above the gear box.
The free end of the shaft is in contact with the inner peripheral surface of a circular rail 18, which is integrally formed on the back surface of the turntable 2 and serves as a friction driven wheel, as shown in FIG. A disengageable friction drive wheel or friction roller 50 is mounted, and the gearbox is supported on a drive shaft 48 on one side and on a mounting pin 51 on the other side.
It is supported by a bearing 52 via.

A compression coil spring 39 interposed between the power cylinder side fork end 38 and the gear box side fork end 400 is attached to the mounting shaft 53 of both front fork ends.
The friction roller 50 is housed in a guide member 55 serving as a bridge at 54 degrees, and as shown in FIG. .

Therefore, when the storage cage 1 reaches the lowest position, the power cylinder 37 of the friction roller raising/lowering mechanism 35
When actuated, the friction roller 50, which was in the laid-down position in 1, becomes the upright position by counterclockwise rotation of the actuating arm 44 (FIGS. 1 and 2), and the friction roller 50 is placed on the back side of the turntable 2. At the same time as it comes into contact with the inner peripheral surface of a certain circular rail 18 (friction driven wheel), the geared motor 4
1 drives the drive shaft 48 and bevel gear 45.
．． 46, and due to this frictional transmission, the turntable rotates using a plurality of fitting sliding rollers 56 (eight in FIG. 3), which are removable in the cage member 6, as a guide.

Further, the power cylinder 57 of the cage clamp device 5 is disposed on the bottom of the pit on either side of the turntable rotation drive device 4, and the crankshaft 57 is arranged in the same manner.
8, the inner arm 59 of the crankshaft is drivingly connected to the power cylinder, and clamp rollers 62 are attached to both arms 61, each of which is equipped with a torsion coil spring 60. In this case, the crankshaft is located perpendicularly to and below the rotary drive shaft 48 of the turntable rotary drive device 4, and the clamp roller forms the storage cage 1 when raised. On the back surface of the cage member 6 and on the axis perpendicular to the longitudinal direction (
Therefore, they are brought into contact with each other in the diametrical direction of the turntable 2, and both sides of the crankshaft are pivotally supported by a pair of bearings 63 disposed on the bottom surface of the pit.

In the diagonal embodiment, the movement of the movable fence 19 from the down position to the upright position and its completion are performed electrically by utilizing the contact between the tip 31 of the pressing rod 29 and the head 32 of the pusher 30. The movable fence is confirmed by following the pusher head at the tip of the rond, and the movable fence is changed from an active position for preventing the opening of the car door in the carryout person position to a non-active position on the side of the cage 1. Or a conversion drive device 20 for doing the opposite.
The above description has been made of the case where the housing cage 1 is installed on one side with respect to the storage cage 1, that is, the suppression rod 29, the crank arm 33, and the return tension coil spring 34 are installed only on the side of the cage. members are provided on both sides of the cage and the pusher 30 of the conversion drive device.
The same objective can also be achieved by arranging the press rods 29 at the center of the front of the cage, connecting the two press rods 29 with appropriate connection rods, and pressing the press rods with the head 32 of the pusher. Of course.

Therefore, when the apparatus of the present invention having the above-mentioned structure is installed, the storage cage 1, which is intended for loading from the direction of arrow B shown in FIG.
When it is circulated and stopped, an appropriate switch means (not shown) such as a stop confirmation switch is operated to operate the pusher 30, and the pusher head 32 moves in the direction of arrow A shown in the figure to push the rond tip 31. As a result, the suppression rod 29 moves to the right (to the left in FIG. 1), so the movable fence 19 (swinging The levers 21, 22; lower connecting rods 23, 24; upper connecting rods 25, 26) are moved from the upright position to the down position while compressing the tension coil spring 34, as shown in FIG. The automobile door opening prevention function reaches the inactive position from the active position.

Therefore, in this state, the upper connecting rods 25 and 26 for preventing door opening, which form the movable fence 19, are configured to be located below the upper surface of the storage cage 1 in the non-operating position, so that they are not placed on the cage. The door of the car to be placed can be opened and closed freely, and there will be no hindrance to the driver getting in or out of the car.

Next, when the storage cage 1 is circulated from the car transporter position, if the pusher 30 is appropriately reversed by the drive means before the cage starts circulating, the tension coil spring 34 which had been stretched by the pusher 30 can be removed. is contracted by the action of the restoring force, and accordingly, the movable fence 19 rotates from the collapsed position to the upright position, that is, from the inactive position for preventing the opening of the automobile door to the active position, and locks the turntable and locks the parking vehicle. As soon as the door protection position is reached, the suppression rod 29 is returned to its original position.

Therefore, the opening of the car door is blocked by the upper connection rods 25 and 26 of the movable fence 19, and the rotation of the turntable 2 is completely locked by the swing levers 21 and 22 of the fence. This makes it possible to prevent accidents that may occur during cage circulation drive.

In addition, a turntable 2 rotatably incorporated in the cage member 6 is installed in order to improve driver safety and parking efficiency by allowing a car that has entered the garage in the forward direction to exit the garage in the same forward direction. It is desirable to rotate the car by 90° or 180°, and this requires a cage circulation drive when the storage cage 1 on which the vehicle is placed reaches its lowest position, as shown in FIGS. 1 and 3. After stopping the system, when the power cylinder 57 of the poppy clamp device 5 is activated, the crank arms 61, 61 of the crankshaft 58 are activated.
is rotated counterclockwise against the springing force of the torsion coil spring 60, 60, and the clamp roller 62, 62 attached to the tip of the crank arm rises while drawing an arcuate trajectory and closes the storage cage. Since the turntable 2 is pressed onto the lower surface of the cage member 6 constituting the turntable 1, the swinging of the cage, which had been a free support, is completely stopped, and smooth and accurate rotation of the turntable 2 can be expected. Become.

Next, the power cylinder 37 of the friction roller raising/lowering mechanism 35 forming the turntable rotation drive device 4 is operated to press the mounting shirts 53 and 54 against the tensioning force of the pile spring 39 toward the cylinder side. When pulled, the actuating arm 44, which is pivotally attached to the gearbox side fork end 40, similarly rotates counterclockwise even if the button is pressed as shown in FIG. 50 rotates from the two-dot chain line position to the solid line position in FIG. Crimp elastically.

At the same time, the button shear 30 is operated to rotate the movable fence 19 of the turntable lock/garage vehicle door protection device 3 from the upright position or operating position to the collapsed position or non-operating position, thereby releasing the locked state of the turntable 2. Then, turntable rotation drive device 4
When the geared motor 41 of the friction roller rotation mechanism 36 that forms Due to the frictional transmission, the turntable is fitted into the circular rail 18 having a channel-shaped cross section and rotated using a plurality of sliding rollers 56 attached to the cage member 6 as a guide.

Therefore, if the turntable 2 is rotated 180 degrees, a car that has entered the storage cage 1 moving forward in the direction of arrow B can move forward in the direction of arrow C and exiting, and the turntable 2 can also be rotated 90 degrees. Then, the car can move forward in the directions of arrows D and E, respectively.

As described above, according to the present invention, a movable fence is pivotally installed on both sides or one side of a storage cage provided with a turntable, and in order to change the direction of a car placed on the cage, When rotating the table, the movable fence is pushed down by a pusher to a position where rotation of the turntable cannot be prevented, thereby enabling the door opening/closing operation of the car and the raising and lowering of the driver.When driving the cage circulation, the movable fence is By raising the turntable, you can prevent the turntable from rotating and accidental contact with other equipment or equipment due to the opening of the car door. The turntable built into the cage can be rotated 90° or 180° using a rotary drive device to move the car forward in any direction and exit the garage.Therefore, the driver can drive the car with peace of mind, making it safe. Furthermore, unlike conventional parking devices, there is no need to install a turntable on the front side of the device or take up open space for turning the car, so it is economical and increases the effective utilization of land. has advantages.
