DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking device for placing and storing a car on a pallet, and more particularly, to a measure for preventing a door of a car mounted on a pallet from being opened.

[0002]

2. Description of the Related Art In a mechanical parking apparatus of this type, when a pallet on which a car is mounted is moved from a car loading section to a parking section or from a parking section to a car unloading section, the pallet is moved when moving. If the door of the automobile is inadvertently opened due to vibration of the vehicle or the like, the door may come into contact with peripheral members and cause damage to the door itself or parking facilities. Therefore, it is necessary to take measures to restrict the opening of the car door on the pallet.

[0003] As a countermeasure for such door opening control, the applicant has proposed, for example, the actual opening 58-19.
No. 057 and Japanese Utility Model Application Laid-Open No. 61-8249. In this conventional example, a frame is provided on both left and right sides of a pallet, has a gap of a predetermined interval or more with respect to a door surface of an automobile mounted on the pallet, and can be raised and lowered in a substantially parallel plane. Door-opening restricting member, a tension coil spring disposed on the lower surface of the left and right sides of the pallet, and constantly urging the restricting member to the upright posture, and installed in the car loading / unloading section, A means for lowering the restricting member against the urging force of the extension coil spring, and when loading the vehicle, placing the vehicle on a pallet in a state where the restricting member is lowered by the lowering means at the vehicle loading / unloading section; Next, the operation of the lodging means is stopped to raise the regulating member by the tension coil spring, and at the time of unloading, the vehicle is unloaded from the pallet in a state where the regulating member is fallen down by the falling means at the vehicle loading / unloading section. Uninasa are.

According to this conventional example, since the regulating member moves up and down in a plane substantially perpendicular to the door opening direction, there is no possibility that the regulating member falls down due to the door opening movement. Therefore, even when the door of the automobile is accidentally opened, it is possible to reliably prevent the door from opening outside the regulating member. In addition, since the regulating member does not contact the door surface, if the distance between the regulating members is set to be large, it is possible to cope with a wide range of vehicle types from a large vehicle to a small vehicle. There is.

[0005]

However, not all of the problems have been solved in the above conventional example. That is, in order to cope with a wide variety of vehicles having different vehicle width dimensions, the regulating member has a gap equal to or larger than a predetermined interval dimension with respect to the door surface, which is insufficient in preventing the door itself from opening, Rather, if the door is opened by mistake, the gap between the two may give the door room for opening and closing movement. The surface may be scratched.

[0006] Further, since the regulating member is basically in an upright posture, it is difficult to hold the regulating member in a laid state, which hinders palletizing and depalletizing at the time of pallet shipping or the like. There are also problems.

[0007] The present invention has been made in view of the above problems, and an object of the present invention is to control the opening movement of a door of an automobile mounted on a pallet, for automobiles having different vehicle widths. Another object of the present invention is to prevent the door of the vehicle itself from being opened, while preventing palletizing and depalletizing of the pallet when the door opening control is not required.

[0008]

In order to achieve the above object, according to the present invention, a door pressing member having elasticity is disposed on both sides of a pallet, and the door pressing member is extended to extend the door pressing member. The door contact portion of the member is pressed against the door surface of the vehicle from the side of the vehicle.

Specifically, according to the present invention, when a vehicle is carried in, the vehicle is placed on a pallet at the vehicle carrying-in section,
While moving the pallet to the parking section,
The premise is a mechanical parking device in which a pallet is moved from a parking section to a car carry-out section, and a car mounted on the pallet is taken off the pallet at the carry-out section.

More specifically, according to the first aspect of the present invention, the door abutment portion is disposed on the left and right sides of the pallet, and in a stretched state, the leading end abutment portion extends from the side of the vehicle on the pallet to the surface of the door of the vehicle. A retractable door pressing member configured to separate the door contact portion from the door surface in a contracted state while being pressed, and a door pressing of a pallet provided in the vehicle carrying portion and provided in the vehicle carrying portion. The vehicle includes an elongating means for extending the member, and a shrinking means arranged in the car unloading section for shrinking a door pressing member of a pallet in the car unloading section.

According to a second aspect of the present invention, in the first aspect of the present invention, the door pressing member has flexibility, and the direction in which the door contact portion is pressed against the door surface in the extended state and the direction in which the door is pressed. It is assumed that each motion is allowed in the orthogonal direction.

According to a third aspect of the present invention, in the first aspect of the present invention, the door pressing member is configured such that the door contact portion is stored at a position substantially along the upper surface of the pallet in a contracted state. And

According to a fourth aspect of the present invention, in the first, second or third aspect of the present invention, the door pressing member is formed of an airtight bag-like member, and the extending means supplies gas into the door pressing member. While the door pressing member is extended, the contraction means is configured to discharge the gas in the door pressing member to contract the door pressing member.

[0014]

According to the first aspect of the present invention, when the vehicle is placed on the pallet at the vehicle entrance, the door pressing members are extended by the extending means on both right and left sides of the pallet.
The door contact portion of the door pressing member presses against the door surface of the vehicle from the side of the vehicle. Due to this pressing force, the door opening movement of the automobile door is regulated. In addition, since the door contact portion is pressed against the door surface from the side of the vehicle, the door contact portion can be displaced in the pressure contact direction, and the door contact portion responds to the magnitude of the vehicle width dimension by the displacement amount in the pressure contact direction. I do. That is,
The door contact portion appropriately presses the respective door surfaces with a small displacement for a vehicle having a large vehicle width and a large displacement for a vehicle having a small vehicle width.

On the other hand, in the vehicle carrying-out section, the door pressing member is contracted by the operation of the contracting means. In this state, the door contact portion is separated from the door surface, and the vehicle is lowered from the pallet without interfering with the door pressing member. be able to.

According to the second aspect of the present invention, when a relative movement occurs between the pallet and the vehicle in a state where the door contact portion of the door pressing member is pressed against the door surface, the door contact portion has the door contact portion. Each movement in the direction of pressing against the door surface and in the direction orthogonal to the pressing direction is allowed by the flexibility of the door pressing member. As a result, the door contact portion follows the movement of the door surface, so that no displacement occurs between the door contact portion and the door surface in the pressure contact direction and the direction orthogonal to the pressure contact direction. Therefore, when the relative movement occurs, a gap between the door contact portion and the door surface or a situation where the door surface is rubbed by the door contact portion is avoided.

According to the third aspect of the present invention, the door pressing member is stored at a position substantially along the upper surface of the pallet in the contracted state, so that the door pressing member is palletized or depalletized when the pallet is palletized or depalletized. Disturbance is avoided.

According to the fourth aspect of the present invention, the door pressing member is formed of a bag-shaped member which is expanded by receiving the supply of gas from the expanding means, while being contracted by discharging the gas by the contracting means.
Compared to the conventional undulating type, it is advantageous in terms of cost, and the possibility of occurrence of malfunction or the like is small because the structure is simple. Further, since the door pressing member can be extended in accordance with the gas supply amount, the door pressing member can be easily extended to an appropriate extended state according to the vehicle width by adjusting the gas supply amount.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 6 shows a mechanical parking device according to this embodiment,
As a basic configuration, the parking device includes a pallet for mounting a car, a car loading unit 1 for mounting the car on the pallet, and a parking section for storing an empty pallet on which the car is mounted. The vehicle 1 comprises a vehicle 2 and a vehicle unloading unit 3 for unloading the vehicle from the pallet. The pallet is moved by a moving means (not shown) between the car carry-in section 1, the parking section 2 and the car carry-out section 3, and an empty pallet is sent from the car carry-out section 3 to the carry-in section 1.

As shown in FIG. 1 to FIG.
An airbag 5 which is a bag-like member as a door pressing member is disposed on both left and right sides (left and right sides in FIGS. 1 and 3). The airbag 5 is made of rubber or a soft synthetic resin and has elasticity in a predetermined direction. When the airbag 5 is inflated, the airbag 5 extends upward as shown in FIGS. While the front end surface is made to be substantially vertical, when contracted, the front end surface is contracted so as to be stored at a position substantially along the upper surface of the pallet 4. The airbag 5 is provided with a large number of substantially rectangular frame members arranged in the direction of expansion and contraction in order to regulate expansion and contraction in directions other than the above-described expansion direction.

The front end surface of the airbag 5 is a door contact surface 5a as a door contact portion capable of contacting the door surface b of the automobile a mounted on the pallet 4. The door contact surface 5a is The door surface b has a moderate flexibility so as not to damage the door surface b at the time of abutment, and the door surface b is not easily displaced in a direction perpendicular to the abutment direction with respect to the door surface b in the abutted state. And a suitable coefficient of friction between them is obtained.

The lower surface of the pallet 4 is shown in FIGS.
As shown in FIG. 2, a supply / exhaust passage 6 having a bifurcated distal end side is formed by piping, and the distal end of the supply / exhaust passage 6 is connected to each airbag 5, and the base end has a compression An air supply / exhaust valve 7 for supplying / exhausting air to / from the airbag 5 is provided, which can be connected to the air injection device 8 and the air exhaust device 17. The supply / exhaust valve 7 is capable of supplying / exhausting when connected to each of the compressed air injection device 8 and the air discharging device 17, while preventing exhaust when the connection is released.

On the other hand, the car loading section 1 has:
As shown in FIG. 4, a compressed air injecting device 8 is installed as extension means for injecting compressed air into the airbag 5. The compressed air injection device 8 is connected to a compression pump 9 for compressing and discharging the sucked air, a motor 10 for operating the compression pump 9, and a discharge side of the compression pump 9. A tank 11 for storing the compressed air discharged from the tank 9, an on-off valve 12 connected to the tank 11 and capable of opening and closing an outflow passage through which the compressed air in the tank 11 flows, and a tip of the outflow passage Connecting part 1 provided on the pallet 4 and connectable to the supply / exhaust valve 7 on the pallet 4 side
3 and a connecting means 14 for moving the connecting portion 13 forward and backward with respect to the supply / exhaust valve 7 of the pallet 4 stopped at a predetermined position of the vehicle carrying-in portion 1. The connecting means 14 includes a holding member 15 for holding the connection portion 13,
And a motor 16 for moving the motor back and forth.

On the other hand, as shown in FIG. 5, an air discharging device 17 as a contracting means for discharging the air in the air bag 5 to the outside is installed in the vehicle carrying-out section 3. The air discharge device 17 is connected to an exhaust pump 18 for sucking and discharging air, a motor 19 for operating the exhaust pump 18, and a suction side of the exhaust pump 18. The vehicle includes a connecting portion 20 connectable to the valve 7, and connecting means 21 for moving the connecting portion 20 forward and backward with respect to the supply / exhaust valve 7 of the pallet 4 stopped at a predetermined position of the vehicle carrying-out portion 3. The connecting means 21
Is composed of a holding member 22 and a motor 23 having the same function as the connecting means 14 of the compressed air injection device 8.

According to the above configuration, the motor 1 is installed in the tank 11 of the compressed air injection device 8 in the vehicle carrying-in section 1.
0, the compressed air discharged from the compression pump 9 is always stored. When the pallet 4 stops at a predetermined position in the car loading section 1, the connection section 13 of the compressed air injection device 8
Is connected to the supply / exhaust valve 7 of the pallet 4 by the connecting means 14. At this stage, the airbag 5 is still in a contracted state. When the automobile a is placed on the pallet 4, the open / close valve 12 of the compressed air injection device 8 is opened, and the compressed air in the tank 11 is supplied to each airbag 5 via the supply / exhaust passage 6 of the pallet 4. Supplied. As a result, as shown in FIGS. 1 and 2, each airbag 5 is inflated in the extension direction, and is in an extended state, and each door contact surface 5a is placed on the door surface b of the automobile a from the side of the automobile a. Each is pressed.

Then, the door-opening movement of the door of the automobile a is regulated by the pressing force. Further, since the airbag 5 expands in the expansion direction according to the supply amount of the compressed air, the airbag 5 expands when the supply amount is large, and expands when the supply amount is small. Thereby, the displacement amount of the door contact surface 5a in the pressure contact direction is adjusted. Therefore, the amount of displacement is reduced by reducing the supply amount for the vehicle a having a large vehicle width, and the amount of displacement is increased by increasing the supply amount for the vehicle a having a small vehicle width. Thereby, the door contact surface 5a can be easily brought into pressure contact with the door surface b in an appropriate state according to each vehicle width dimension. Further, since the pressing force of the door contact surface 5a against the door surface b also changes according to the supply amount, for example, when the door is in a half-door state, if the supply amount of the compressed air to the airbag 5 is increased, The door can be forcibly closed by the pressing force.

The airbag 5 has a simple structure in which the airbag 5 expands and expands when compressed air is supplied, and contracts and contracts when the internal air is discharged. It is advantageous in terms of cost as compared with the conventional undulating type, and the possibility of malfunction or the like is small because of the simple structure.

In the state where the door opening is restricted, the pallet 4 is moved from the vehicle entrance 1 to the parking section 2 and from the parking section 2 to the vehicle exit 3 respectively. At this time, if relative movement occurs between the pallet 4 and the vehicle a while the door contact surface 5a is in pressure contact with the door surface b, the pressure contact direction of the door contact surface 5a with respect to the door surface b Each movement in a direction orthogonal to the pressure contact direction is allowed by the flexibility of the airbag 5, so that the door contact surface 5
Since a follows the movement of the door surface b, no displacement occurs between the two surfaces in the pressure contact direction and the direction perpendicular to the pressure contact direction. Therefore, even when the relative movement occurs, the door contact surface 5a is separated from the door surface b and the door opening regulation is not performed, or the door contact surface 5a is displaced in a direction orthogonal to the pressure contact direction. It is possible to avoid a situation in which b is damaged.

On the other hand, when the pallet 4 on which the automobile a is placed is held at a predetermined position, the connecting portion 20 of the air discharging device 17 is connected to the pallet supply / exhaust valve 7 of the pallet by the connecting means 21 in the car carry-out section 3. Is done. When the exhaust pump 18 is operated by the drive of the motor 19, the air in each airbag 5 is exhausted to the outside, and each airbag 5 contracts in the contracting direction, and each door contact surface 5a is moved to the upper surface of the pallet 4. Is stored at a position substantially along the line. Thereby, the airbag 5
Is released, and the vehicle a is lowered from the pallet 4.

When the compressed air is exhausted and the air bag 5 is contracted, the door contact surface 5a is stored at a position substantially along the upper surface of the pallet 4, so that the pallet 4 can be palletized or depalletized. The obstacle to the airbag 5 is avoided.

In the above-described embodiment, the car carry-in section 1 and the car carry-out section 3 are provided independently of each other. However, the both may be combined into a car carry-in / out section. It is preferable that the function of the air discharging device 17 is also used in the device 8.

[0032]

As described above, according to the first aspect of the present invention, when regulating the opening movement of the door of the automobile mounted on the pallet, the door contact portion at the tip of the door pressing member is adjusted to the automobile. The door surface of the vehicle is pressed against the side of the vehicle, so that the vehicle itself can be prevented from opening itself with respect to vehicles having different vehicle width dimensions, and the door itself caused by the door opening can be prevented. In addition, it is possible to prevent damage to parking facilities and the like. Further, if the door contact portion is strongly pressed against the door surface, for example, the door in the half-door state can be forcibly closed.

According to the second aspect of the present invention, the door pressing member is provided with flexibility so that the door contact portion follows the movement of the door surface. Even if the car moves, it is possible to reliably maintain the door opening restriction state for the door, and to prevent a situation in which the door abutting portion is displaced while being pressed against the door surface and the door surface is damaged. It can also be avoided.

According to the third aspect of the present invention, when it is not necessary to regulate the door opening, the door pressing member can be contracted so that the door contact portion is stored at a position substantially along the upper surface of the pallet. Therefore, it is possible to avoid a problem in palletizing and depalletizing when the pallet is shipped.

According to the fourth aspect of the present invention, the door pressing member is a bag-like member, and the opening of the door is controlled by supplying gas into the bag-like member by the extension means at the vehicle entrance. In the car carry-out section, the door opening regulation is released by evacuating the gas in the bag-shaped member by the shrinking means, so that the structure is simple, low cost and mechanical problems such as malfunction. Less defects.
