Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to parking equipment for automobiles, and more particularly to a multi-level parking system.

(Prior Art) In recent years, the country has been developing cities based on the premise that transportation is primarily based on automobiles. On the other hand, not only in industry but also in ordinary households, there is a tremendous tendency to rely on automobiles as a means of transportation.As a result, the number of automobiles owned has increased dramatically, and today there are few households that own more than one automobile. do not have.

As a result of the above-mentioned circumstances, the number of automobiles has increased dramatically in Japan in recent years, and especially in large cities, the shortage of parking lots and the soaring fees for paid parking lots have become serious problems.

One of the main reasons for this is that, with land rents soaring, parking lot management is not efficient compared to the area of land used. Another reason is that when constructing houses in urban areas, there is not enough land available to provide parking lots and garages, making it difficult to find a parking lot for a private car, let alone a second parking lot. be.

Conventionally, as a means to solve the above-mentioned problems, construction of three-dimensional parking structures including basements and rooftops of buildings has been progressing. In addition, efforts are being made in architectural planning to maximize the margins of building wall and floor area ratios for parking lots.

As a proactive measure, the parking lot is equipped with movable shelves that move up and down where cars are parked, and current cars are stored on the upper level of cars parked on the parking floor. Three-dimensional parking systems are popular. However, in this conventional multilevel parking system,
In order to unload a car stored on a movable shelf, it is necessary to remove another car stored on the floor below it, so unloading a car on the movable shelf requires complicated operation of equipment. The troublesome work of moving cars stored on the lower floor is required. Because of this hassle, many people are required at temporary car storage facilities, which causes costs to rise. Furthermore, there is a potential problem that the stored vehicles may be damaged due to the repeated movement of the vehicles required when the vehicles are put in and taken out of the warehouse. As another specific example, two or three rows of three tiers of car storage shelves are provided, centered on the first floor, on the second floor (upper level) and underground (lower level), and five or We installed shelves to store 8 cars, and the work of changing the vertical and horizontal directions of this large number of shelves was
There is a known car storage system for paid parking lots that uses complex cubic-type control, but this system not only requires the human resources of Somura to control and manage it, but also A large amount of equipment cost is required. Therefore, the actual situation is that even though the number of stored units has increased, the operating efficiency has not improved.

As mentioned above, although the multilevel parking system of the prior art can sometimes achieve the purpose of doubling the number of cars that can be accommodated, due to the problems mentioned above, there are times when the management efficiency of the parking lot is affected. In some cases, this can lead to an increase in parking lot storage service fees. Furthermore, even when these parking devices are installed for private use, there is a tendency for people to not be accustomed to using them because their use involves the above-mentioned troublesome work and the dangers associated with parking. .

Therefore, even though they are acutely aware of the necessity of installing or expanding a parking lot, there are many cases where they are unable to proactively install the multi-level parking system as a means to do so. For these reasons, the lack of parking lots and the soaring prices of parking in large cities are difficult to solve, and are predicted to become even more serious problems in the future.

(Problems to be Solved by the Invention) The present invention was made in view of the above-mentioned problems and inconveniences of parking lots and multi-level parking systems. Unfortunately, it is desirable to provide a multilevel parking device and a parking system that eliminate the need to move another vehicle stored on the floor below it one by one.

It is also possible to provide a movable shelf 2 or the like to catch the fall of the movable shelf 2 or the like in a stepwise position.

4) As the flexible material (6, 6') for suspending the unbalanced load part of the movable shelf 2, the already mentioned chain (
Various types of chains or wires) can be said to be suitable materials, but as long as they have some flexibility, such as applying a small diameter rod to the suspension part other than the part wound around the pulley 38 in the embodiment, It can be changed to other materials as appropriate.

5) Further, due to the structure of the present invention, the number of supports 1a of the main body 1 may be one, which is not shown in the embodiment, or may be three, or four, etc. In this case, the design of the chain 5 (or chain 5 and chain 6) that suspends the movable shelf 2nd class elevating body and the arrangement of the transmission system mechanism related to the chain should be designed to ensure the horizontal state of the elevating body and the balance of the load. It is sufficient to set the condition as appropriate to maintain the condition. In addition, in this case, the configuration of the fall prevention device for the movable shelf 2 etc. elevating body, which is constituted by the arm 10 and the corresponding engagement surface 12, is also as follows:
It is desirable to configure the structure according to the number and arrangement of the supports 1a.

7) Furthermore, when implementing the present invention, a roof may be provided to cover the device.

8) In addition, since an inappropriate state of the stopping position of a car when it is parked in a garage can cause an accident, a device may be installed that has a function of detecting and notifying this state.

9) Regarding the operation of the multi-level parking device included in the present invention, the only way to operate the multi-story parking device is to attract and align the mounting surfaces 4a and 4b provided at the level position of the car loading/unloading floor. For this operation, it is preferable to provide a dedicated switch for each of the mounting surfaces 4a, 4b, and when the device of the present invention is used as equipment for a paid parking lot, the switch It is desirable to equip the vehicle with a switch that calculates the time and detects the amount of toll input, for example, a switch that includes the locking function used in coin lockers. It is equipped with a stopper means for blocking exit from the warehouse, and is constructed so that the stopper means is brought close to the door when the door is unlocked.

10) Furthermore, regarding the stopper means for blocking the vehicle from leaving the garage, as shown in FIG.
The mounting surfaces a and 4b are controlled so as to be able to stop at intermediate positions at different heights relative to the vehicle loading/unloading floor, and a noticeable step is formed between these intermediate positions, that is, the floor and each mounting surface. Even if the intermediate position is the normal stopping position,
It is possible to block the entry and exit of cars, and it is possible to manage theft prevention in unmanned parking lots.

11) Furthermore, the movable shelf 2 can be equipped with a device that captures lifting force on the movable shelf by means of a balance weight, in addition to the above-mentioned suspended and driven device, in order to save energy.

12) Although this application includes at least five basic inventions and a large number of related inventions, it goes without saying that many of these inventions can be implemented separately by combining with prior art. For example, means for compensating for unbalanced loads can also be implemented in conventional parking devices with only one support surface.

13) The present invention provides a suspension driving method for a multi-level parking system for heavy loads having a movable shelf with two upper and lower loading surfaces. The present invention can also be implemented in a parking device that is subjected to heavy loads such as a small truck loaded with cargo or a medium-sized passenger car.

(Operations and Effects) Since the present invention is implemented based on the above-described method and structure, the following operations and effects can be obtained.

The upper and lower mounting surfaces 4a of the movable shelf 2 of the device
, 4b, a switch is operated to bring each mounting surface to the height of the loading/unloading floor. This simple operation drives the electric motor 30 in a predetermined direction, and the power is transmitted through the configured transmission system to drive the movable shelf 2 via the chain 5 (or the chain 5 and the chain 6). Here, if you want to attract the upper A lid surface 4a to the floor, a switch (not shown) for attracting the upper mounting surface 4a is used.
Put in. During this operation, if the drive shelf 2 is in the raised position or in the intermediate position according to the other embodiment 10, it will be lowered so that the upper loading surface 4a is at the same height as the loading/unloading floor. Attracted and held. Further, when it is desired to take a car in or out of the lower T-number surface 4b, a switch (not shown) for attracting the lower AI surface 4b is operated.

With these simple operations, each mounting surface 4a of the movable shelf 2,
4b can be arbitrarily and easily selected to be placed in a position parallel to the vehicle entrance/exit floor. In addition, in this operation, even if a car is parked on either the upper or lower mounting surface 4a, 4b, the upper and lower mounting surfaces are configured to be fixed and operate together with each other. Therefore, it does not pose an obstacle to its operation.

Furthermore, even when the pillar 1a supporting the movable shelf 2 is far away from the center of the weight and load of the movable shelf as in the embodiment (FIG. 2), the chain 6.6' By providing a means for compensating for the unbalanced load caused by the suspension of 2, most of the unbalanced load can be compensated for. Therefore, smooth operation can be provided even under the heavy load of two automobiles placed on the movable shelf 2. Furthermore, since the chain 6 (and 6') that suspends the unevenly loaded portion is made of a flexible material rather than a rigid material such as a support, even if the chain 6 (and 6') comes into contact with the vehicle when loading or unloading the vehicle. Damage to the vehicle and damage to the device can be minimized. Furthermore, if the main body 1 is equipped with means for compensating for this unbalanced load, it is possible to reduce the number of supports 1a of the main body 1, which is advantageous in terms of technology and cost. Furthermore, since the cantilever structure allows the number of columns on the vehicle loading/unloading side to be reduced, the frontage dimension of this multilevel parking system is increased by a dimension corresponding to the width of the column, making it easier to load and unload the vehicle. The mounting surfaces 4a and 4b are equipped with an adjustment device 9 for finely adjusting the length of the chain at the joint with the suspended chain 6 (and 6'). Since the level of engagement between the mounting surface and the loading and unloading floor is adjusted correctly, the operation when loading and unloading the car is smoothed.

During the above-mentioned operation, the fall prevention device for the elevating body, that is, the movable shelf 2 normally operates as follows.

The end 10a of the arm 10 is installed at a constant distance from the engagement surface 12 set on the main body, and during normal operation, the end of the arm and the engagement surface 12 are The chain 5 that is not in pressure contact, that is, suspends the movable shelf, is connected to the end 10b of the arm 10, and since the movable shelf 2 is suspended via the arm 10, the chain 5 is suspended. The arm 10 does not rotate unless the force is lost, and therefore, the movable shelf 2 is not in a locked state under normal circumstances, allowing smooth operation of the movable shelf 2.

Furthermore, this device has a rack 2 on the engagement surface as shown in Fig. 7.
3 and a pinion 2 at the end 10a of the arm.
2 are provided, and these are configured to mesh with each other, the movable shelf 2 is allowed to slide because the pinion is rotatably provided. In addition, as shown in the embodiment shown in FIG.
4, by maintaining a considerable distance between the tip of the arm 10 and the tip of the retaining protrusion 24, this protrusion will not interfere with sliding during normal operation. Must not be.

This fall prevention device for the elevating body, that is, the movable shelf 2 provides the following functions and effects against the risk of falling due to various causes as described below.

That is, when the chain 5 suspending the movable shelf 2 is cut, the tension of the chain is released.

The end portion 10b of the arm falls in the direction of rotation about the shaft center due to its own weight and engagement friction generated on the engagement surface 12 portion. Due to this action, the arm 10 pivots about the pivot shaft 11, and the engagement side end 10a thereof is perpendicular to the engagement surface 12 set on the main body of the device, and an imaginary line H passing through the pivot point is formed. It operates in a direction in which the angle α of the arm, which is used as a reference, becomes an even more acute angle. By this operation, the engagement side end 10a of the arm is pressed against the engagement surface 12. # Due to the pressure contact, a strong PJ frictional resistance is generated between the engagement surface 12 and the arm end flfll l Oa, and this frictional resistance promotes the pivoting action of the arm lO, and the end of the arm is aligned with the axis of the pivot point. 11 and the engaging surface 12 in a wedge shape, and is locked by providing a strong tensioning action.

In addition, according to the configuration in which a spring 14 is provided to resist the tension of the chain 5 that suspends the elevating body, the end portion 10 of the arm is damaged by the elastic torque of the spring in the event of an emergency. b is forced down in the direction of rotation, and said arm responds quickly and operates.

As shown in the embodiment shown in FIG. 6, when the distal end of the arm 10 is equipped with a rotatable roller 21, the engagement surface 12 and the distal end of the arm (10a) can be It is possible to reduce the friction with and the wear caused by this friction. In this case, it is possible to create a structure in which a certain amount of light friction occurs between the rollers, etc. and the arm 10, so that large resistance is generated only when the movable shelf slides at a high speed equivalent to falling. Due to the frictional resistance, the effect of further improving the responsiveness related to the forced pivoting operation of the arm that occurs after the roller contacts the engagement surface can be obtained.

Furthermore, if rubber or the like is pasted around the roller, its elasticity and high coefficient of friction will further improve the responsiveness of the operation.

As shown in FIG. 7, according to a configuration in which a binion 22 is provided at the tip end 10a of the arm 10 and a rack 23 is provided at the opposing engagement surface, the distance between the contact surfaces of the rack and the binion can be It is possible to set and configure the distance to a minimum, and the above-mentioned responsiveness is further improved, or reliable responsiveness that is not affected by assembly errors of the device related to the set distance can be obtained.

Furthermore, as shown in FIG. 8, the engaging surface portion 12 on the main body side
If a multi-stage engagement protrusion 24 with which the tip of the arm can engage is provided, a considerably large amount of movement corresponding to the height of the protrusion related to the rotation angle of the arm IO is required. Although this reduces the responsiveness of the device, on the other hand, it has the advantage of providing a reliable stopping function in which the tip of the arm engages with the engagement protrusion to catch the falling of the elevating body.

Incidentally, if the movable shelf falls due to a cause other than the breakage of the chain 5 suspending the movable shelf, that is, if there is an ohm, ohmic foil, or pulley somewhere in the transmission system for winding up or unwinding the chain. If the key or pin, etc. that stops between the drive shaft and the motor brake is damaged, or if a fall occurs due to a failure of the motor brake, the cut part of the broken bottle or key, etc., may be damaged, etc. There is a possibility that it will add resistance to idling. Therefore, in the event of a falling accident of a lifting object such as a movable shelf due to this cause, the suspended chain (or wire) will maintain some tension during the falling stroke and will not cause any deflection. A spring 14 is provided against the suspension/tension direction of the chain 5 for the arm lO for capturing the chain 5, and the spring 14 is provided with a spring 14 in the direction of suspension/tension of the chain 5. Movable shelf 2
By adjusting the impact force to be high enough to correspond to the chain's own weight, even if the chain falls while maintaining some tension due to an accident other than the chain breaking, the chain will resist the residual tension of the chain. the arm 10 responds, and then engagement friction occurs between the arm tip 10a and the engagement surface 12, forcing the arm 10 to rotate;
It can perform the functions related to the lock described above.

In addition, the pulley is slid in the axial direction as the pulley rotates, and the position is moved corresponding to the winding pitch of the chain, wire, etc.! l
This makes it possible to wind long lengths using only the winding pulley without installing a driven wheel, and since each chain is wound in a spiral shape, each chain does not overlap each other, resulting in a faster winding speed. and no dimensional disturbance,
Furthermore, since there is no change in the suspension point, it is possible to reduce costs without deteriorating functionality.

In addition to providing the above-mentioned functions and effects, the main objective of the present invention is to facilitate the operation of loading and unloading a car onto the upper loading surface of a multi-level parking system, regardless of whether or not the lower level is parked. can.

Since the present invention can be implemented without a support on the car loading/unloading side, there is an advantage that a parking device with a wide frontage on the car loading/unloading side can be provided.

Furthermore, the present invention provides a means for suspending the unbalanced load portion and compensating for the unbalanced load, thereby making it possible to smoothly raise and lower a highly loaded movable shelf for two automobiles using a device with a cantilevered structure. becomes. This cantilevered structure or a structure similar to a cantilevered structure allows the number of pillars to be set to a minimum, making it possible to provide the multilevel parking system at an extremely low cost.

Furthermore, by equipping the elevator with the fall prevention device of the present invention, it is possible to prevent the danger of the elevator falling due to any imaginable cause.

From the above, the present invention can achieve a wide variety of effects in that all the objectives related to solving the problems to be solved mentioned above can be appropriately achieved.

The multilevel parking system constructed based on the present invention has the advantage that it can be used for bicycle parking if desired.
