Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanical parking device in which a tray placed on top of a car and on which a car or the like is to be placed is rotated, and particularly to a mechanical parking device that stabilizes the tray rotation and reduces the weight of the cage. This relates to a vertical circulation parking device designed to reduce the amount of damage caused.

Conventionally, the above type of vertical circulation parking device has been disclosed in Japanese Patent Application Laid-open No. 56-20278 and Japanese Patent Publication No. 57-37745.
A parking device has been proposed in which a turntable is incorporated into a storage cage as disclosed in the above publication, but in this device, a circular rail with a channel-shaped cross section forming the turntable has a
The storage cage is designed to rotate using a plurality of sliding rollers (eight in the illustration) as a guide, which are attached to the cage members. Since it is necessary to widen the installation space for the rollers and reduce the load, the dimension of the material must necessarily be increased from the viewpoint of strength, so the installation height per unit becomes high. The disadvantage is that the weight of the cage increases, the total number of cars accommodated is reduced, and the cost is increased.

In contrast, the present invention aims to provide a vertical circulation type parking device that can eliminate the above-mentioned drawbacks, and the gist thereof is to provide a parking device that is attached to the upper surface of the cage member of each cage. Rotating trays having the function of a turntable each having a circular rail integrally formed on the back surface that fits with a plurality of tray overturn prevention rollers are arranged in an overlapping manner, and are placed in a pit corresponding to the lowest position of the cage. , a rotating tray pedestal elevating mechanism and a tray rotating drive mechanism are installed; in this case, the revolving tray pedestal elevating mechanism is arranged at the front and rear of the cage in the longitudinal direction in conjunction with a power cylinder unit provided on the bottom surface of the pit; The drive mechanism for tray rotation is formed from a rotating tray mount, a group of main rollers for supporting the tray disposed on the mount, and a friction transmission means for tray rotation, When the rotating tray reaches the lowest position, the rotating tray mount is slightly raised by the operation of the lifting mechanism, and the rotating tray is rotated via the circular rail by the tray rotating friction transmission means. This lies in the fact that

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

In FIGS. 1 and 2, 1 is a storage cage in which a car is to be placed, 2 is a revolving tray that is placed on top of the cage and has the function of a rotatable turntable, and 3 is a revolving tray lock and storage vehicle. Door protection mechanism, 4 is a rotating tray pedestal lifting mechanism, 5
1 and 2 respectively show a drive mechanism for rotating the tray, and the storage cage mainly consists of a cage member 6 assembled in the shape of a grid, gate-shaped hangers 7 installed at both ends of the cage member in the longitudinal direction, and the upper parts of these hangers. and a rotating tray 2 which is superimposed on the cage member and is rotatable.
A pair of wheel stoppers 9 are formed on the rear side of the upper surface of the revolving tray, and a circular rail 10 with an angular cross section and serving as a friction driven wheel is formed at the center of the lower surface. A center post shaft 11 located at the center is fixed. The rotating tray lock/car door protection mechanism 3 is a pair of parallel four sides arranged on opposite sides (or on one side) located corresponding to the lower center of the car door installed on both sides (or one side) of the storage cage 1. A movable fence 12 forming a shape link and a conversion drive device (not shown) such as a pusher for converting the movable fence from a working position (upright position) to a non-working position (lowered position) or vice versa. Four tray overturn prevention rollers 14 are installed between the girder members 13 forming the cage member 6 to fit and slide on the integrally formed circular rails 10 of the rotating tray 2, and at the center of the circular rails. The center post shaft 11 located and fixed on the lower surface of the rotating tray has three radial support legs 16 made of pipes, one end of which is fixed to a bracket 15 hanging from the cage member 6 and the girder member 13. The tray 2 is pivotally supported by a bearing 17 installed at the end, and the tray 2 is thereby pivoted about the center post shaft 11 in the direction of the hour hand (or counterclockwise) as shown by the arrow.

As shown in detail in FIGS. 3 and 4, the revolving tray pedestal lifting mechanism 4 disposed on the bottom surface 19 of the pit 18 is connected to a power cylinder unit 20 pivotally mounted on the pit bottom surface. It consists of crankshafts 21 and 22 located at the front and rear with respect to the direction of entry of the vehicle, which are linked to the engine, and in this case,
Both crankshafts are pivotally supported by a pair of bearings 24 and 25 on a common base 23 installed on the bottom of the pit, and the rod 26 of the power cylinder unit is connected to a power transmission lever 27 installed on the crankshaft 21. The drive motor 28 and cylinder 29 of the power cylinder unit are mounted on the bracket 3 on the common base.
It is centered at 0. Also, crankshaft 2
Double arm lever 3 attached to both ends of 1 and 22
1 and 32 are push-up rollers 33 and 34, respectively.
The connecting levers 35 and 36 attached to these crankshafts are connected by a rod 37, and the rod 26 of the power cylinder unit 20 is connected as shown in FIGS. 2 and 4. When pushed in the direction of arrow A, the double-arm levers 31 and 32 rotate in the direction of the hour hand via the power transmission lever 27 (in the opposite case, they rotate in the direction of the counter-hour hand), thereby causing the push-up rollers 33 and 32 to rotate in the direction of the hour hand. 34 is lowered (raised).

The tray rotation drive mechanism 5 mainly includes a rotating tray pedestal 35' having a substantially rectangular shape whose longitudinal and lateral movements and horizontal movements are regulated by appropriate guide means, and which are disposed radially and on the same circumference on the pedestal. 8 main rollers 36', a motor 37', a reducer 38, a transmission shaft 40 connected to the reducer via a universal joint 39, and a friction roller 41 attached to the tip of the shaft. The four corners of the rotating tray mount are connected to the double-arm levers 31 of the crankshafts 21 and 22,
4 push-up rollers 33 clamped to 32,
34 and is raised (lowered) by rotation of these push-up rollers or dual-arm levers in the counterclockwise direction (hour hand direction). The motor and the speed reducer are pivoted to rotate along the circumferential direction and come into contact with the lower surface of a circular rail 10 formed on the back surface of the rotating tray 2 at the upper limit of the rise of the rotating tray mount, and the motor and the speed reducer As shown in FIG. 5, it is installed on a support frame 44 protruding from both side steps 43 formed at the longitudinal center of the revolving tray mount, and the transmission shaft A support bracket 45 is positioned on the center line of the section, that is, corresponding to the diameter direction of the circular rail, and is connected to the universal joint on one side, and is elastically mounted on the support bracket 45 on the other side stretched over the step. It is pivotally supported by a bearing 46.

As shown in detail in FIG. 5, one end of the bearing 46 elastically mounted on the support bracket 45 is loaded with a spring force by a coil spring 47 disposed on the support bracket, and the other end is loaded with a spring force. is mounted on a support plate 49 which is pivotally connected to a mounting bracket 48 installed on the support bracket, whereby a friction roller 41 mounted at the tip of the transmission shaft is elastically loaded. The rotating tray 2 can be rotated stably and smoothly by being brought into contact with or in contact with the lower surface of the circular rail 10 at all times.

Next, in the device of the present invention having the above configuration,
For example, a storage cage 1 for carrying a car
When the tray is driven and circulated to a predetermined loading/unloading position, that is, the cage's lowest position, and then stopped, an appropriate switch means such as a stop confirmation switch is activated, and a conversion drive device (not shown) such as a pusher is activated to lock and store the rotating tray. A movable fence 12 of parallelogram links forming the vehicle door protection mechanism 3 reaches a lowered position (inactive position) from an upright position (active position) for preventing the opening of the vehicle door. Therefore, since the movable fence 12 is positioned below the top surface of the storage cage 1, the door of the car stored in the cage can be freely opened and closed, and the driver can also easily enter and exit the car. There is no problem in getting on and off the vehicle.

Next, when the storage cage 1 is driven to circulate from the car loading/unloading position, the movable fence 12 is moved from the collapsed position to the upright position by reversing the conversion drive device such as a pusher by an appropriate means before starting the circulating drive of the cage. Since the cage rotates to reach the rotating tray lock and storage car door protection mechanism, it is possible to prevent an accident with the door ajar when the cage is circulated.

Furthermore, in order to improve driver safety and parking efficiency by allowing cars that have entered the garage in the forward direction to exit the garage in the same forward direction, the rotating tray 2
90° for side entry type parking devices, and
In the case of a front entry type parking device, it can be rotated 180 degrees, as shown in Figure 4.
The storage cage 1, which is driven and circulated to the car loading/unloading position by pressing a call button (not shown) as appropriate, is driven by guide rollers and guide members (both not shown) provided on the end surface of the cage member 6 or the upper surface of the hanger 7. Stops in place without shaking. Next, if the power cylinder unit 20 is activated to pull the rod 26 in the direction of arrow B,
Until then, the rotating tray mount 35' of the rotating tray gantry lifting mechanism 4 was in the position shown by the two-dot chain line.
At the same time as the push-up rollers 33 and 34 supporting the rotating tray rotate in the counterclockwise direction, the lifting mechanism as a whole rises, and the eight rollers provided on the same circumference and radially on the upper surface of the rotating tray mount are raised as a whole. main roller 36'
A circular rail 1 is formed on the back surface of the rotating tray 2 with position regulating stoppers 50 such as jacks provided at the four corners of the rotating tray mount, which are adjusted in advance.
0 and the cage member 6 or girder member 13 forming the storage cage 1, and lifts the revolving tray slightly, thereby detaching the revolving tray from the cage member or girder member. At this point, the operation of the power cylinder unit is stopped.

On the other hand, as the rotating tray pedestal 35' is raised by the operation of the rotating tray pedestal lifting mechanism 4, the friction roller 41 of the tray rotating drive mechanism 5 comes into elastic contact with the lower surface of the circular rail 10. 2 does not swing.Next, when the motor 37' is operated, the friction roller 41 attached to the tip of the transmission shaft 40 rotates via the reducer 38 and the universal joint 39. Through the transmission, the rotating tray is rotated through a predetermined entry/exit angle, for example, 90° or 180°, as described above.

Furthermore, if the motor 28 is stopped in this state and the power cylinder unit 20 is reversely operated, the rod 26 is pushed in the direction of arrow A, and the push-up roller 3
3 and 34 are a power transmission lever 27 and a double-arm lever 3
The rotating tray 2 is completely placed on the cage member 6 of the storage cage 1 because it rotates in the direction of the hour hand while supporting the rotating tray pedestal 35' of the tray rotating pedestal lifting mechanism 4 via the tray 1 and 32. At times, the vehicle can be taken out of the garage in the forward direction, and then the push-up roller rotates in the direction of the hour hand while supporting the rotating tray mount, reaches the position shown by the two-dot chain line, and returns to its original position.

As described above, according to the present invention, the following effects are achieved.

(1) Each cage is equipped with multiple tray overturn prevention rollers so that the load is mainly applied to the suspended side of the storage cage, and the main load when turning is received by the main roller group that rises from below. This allows for an increase in the number of machines accommodated by reducing the installation height.
The cage weight and cost can be reduced.In addition, the main roller group acts as a steady rest by pressing the storage cage and the tray while the tray is rotating, and the tray can be rotated stably. rotation is possible.

(2) After a car is stored in the storage cage in the forward direction for storage, the revolving tray can be rotated 90° or 180° and the car can be taken out in the forward direction. Therefore, the driver can drive the car with peace of mind. Therefore, it is safe, and since there is no need to provide a turntable in front of the parking device or to take up a vacant space for changing the direction of the car, it is economical because the effective use of land is improved.
