Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking management system and a parking management system for an automobile or the like installed in a parking lot, and more particularly to a locking system using a cylinder such as an air cylinder and a novel structure which has not been available. The present invention relates to a parking management device and a parking management system that can maintain the posture of a member and thereby effectively prevent an unauthorized escape of an automobile or the like.

[0002]

2. Description of the Related Art Conventionally, as a parking management device of this kind,
As disclosed in Japanese Patent Application Laid-Open No. 2000-310053 and the like, a lock member is driven upside down using an electric motor, and Japanese Patent Application Laid-Open Nos. 9-96123 and 11-63.
As disclosed in Japanese Unexamined Patent Publication No. 24, Japanese Unexamined Patent Publication No. H11-50687 and the like, there is an apparatus that uses an air cylinder to control the inversion of a lock member based on the movement of the cylinder shaft.

[0003]

However, in these conventional parking management devices, if no measures are taken, a strong force can be applied to the lock member so that the standing lock member can be forcibly knocked down.

Instead of locking the tires of a car,
Since the height of the locking member for locking the bumper of an automobile becomes high considering the minimum ground height of the automobile, etc., especially in combination with an air cylinder, the principle of leverage is relatively high. The lock member can be defeated only by applying a small force to the lock member.

[0005] As a result, an immoral user can forcibly push down the lock member and escape without paying a fee.

Therefore, in the conventional parking management device, a stopper mechanism such as a rack and pinion for holding the position of the lock member is provided separately from the electric motor and the cylinder, and the stopper member is used to hold the position of the lock member. It is designed to prevent illegal escape such as illegal.

However, when the stopper mechanism for holding the posture of the lock member is provided separately from the cylinder, another problem as described below occurs at least.

Since the locking member is prevented from falling by the stopper mechanism, the locking member cannot be tilted even if the drive means controls the tilting.
Therefore, the structure of the mechanical part is complicated by the stopper mechanism, and the circuit configuration of the control means for controlling the inversion of the lock member is also complicated.

In particular, in the configurations disclosed in Japanese Patent Application Laid-Open Nos. 11-6324 and 9-96123, control of this stopper mechanism is performed in order to maintain the advantage of using an air cylinder instead of an electric motor. Also use air cylinders, and use two air cylinders that are significantly more expensive than an electric motor. And, with such a configuration, the price of the parking management device will be significantly increased as compared with the case where the electric motor is used,
It is never really acceptable in the market.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has a simple structure without a complicated structure of a parking management device or a control device thereof, even if a lock member using a cylinder is driven. Another object of the present invention is to provide a parking management device and a parking management system in which it is difficult to push down a lock member.

[0011]

In order to achieve the above object, a parking management device according to the present invention comprises a housing, a lock shaft rotatably supported by the housing, and a lock shaft fixed to the lock shaft. A lock member that is inverted according to rotation of the shaft, a drive plate fixed to the lock shaft, a connection hole opened in the drive plate, a connection shaft movably inserted into the connection hole, A support surface that is fixed to the housing and holds the connection shaft such that the connection shaft and the connection hole are in contact at one place, and a driving unit that moves the connection shaft along the support surface of the support surface; It is provided with.

According to this structure, since the connecting shaft and the connecting hole are held so as to be in contact with each other at one position on the supporting surface, even if the locking member is to be tilted, the force of tilting is less likely to be transmitted to the driving means. . As a result, there is no need to provide a stopper mechanism for holding the attitude of the lock member separately from the driving means, and even if a relatively weak force is used as the driving means, the attitude of the lock member is maintained. Can be. Further, by using such a weak driving means, it is possible to reduce the size and weight of the parking management device.

[0013] A parking management device according to the present invention includes a housing,
A lock shaft rotatably supported by the housing, a lock member fixed to the lock shaft and inverted in response to rotation of the lock shaft, a drive plate fixed to the lock shaft, and the drive plate Connection hole opened in
A connection shaft movably inserted into the connection hole, a support surface fixed to the housing and holding the connection shaft so as to reduce a contact portion between the connection shaft and the connection hole, and the connection shaft. Drive means for moving the support surface along the support surface.

With this configuration, the contact portion between the connection shaft and the connection hole is reduced on the support surface, so that even if the lock member is to be tilted, the force of the lock member is less likely to be transmitted to the driving means. As a result, there is no need to provide a stopper mechanism for holding the attitude of the lock member separately from the driving means, and even if a relatively weak force is used as the driving means, the attitude of the lock member is maintained. Can be. Furthermore,
By using such weak driving means, it is possible to reduce the size and weight of the parking management device.

[0015] In the parking management device of the present invention, the connection hole may be:
An angle between a line segment connecting the contact point where the connection shaft contacts with the lock shaft and the tangent line of the connection shaft is greater than 0 degrees.

According to this structure, since the angle between the line segment connecting the contact point of the connecting shaft and the lock shaft and the tangent line of the connecting shaft is larger than 0 degrees, the connecting shaft and the connecting hole are not connected to each other. Is held down so as to be in contact with one place, the force for tilting the lock member is always attenuated and transmitted to the driving means.

[0017] In the parking management device according to the present invention, the support surface includes:
The connecting shaft is held so that the connecting shaft and the connecting hole are in contact at one place within a predetermined inverted angle range of the lock member.

With this configuration, when the lock member is within the predetermined inverted angle range, the force for tilting the lock member is always attenuated and transmitted to the driving means. Even if a pressing force is applied before standing up, the locking member can be reliably started up against this force.

[0019] In the parking management device of the present invention, the driving means includes a cylinder housing slidably provided in the housing, and a cylinder shaft provided to be extendable and retractable from one end of the cylinder housing. The connecting shaft is moved by a cylinder.

With this configuration, the connecting shaft can be moved by the cylinder and the posture of the lock member can be maintained.

[0021] In the parking management device of the present invention, the connection hole may be:
It is formed in a substantially rectangular shape or a substantially triangular shape.

According to this structure, since the connecting hole is formed in a substantially rectangular shape or a substantially triangular shape, the position of the lock member within the inverted angle range can be determined by a simple hole processing. Also, the connecting shaft and the connecting hole can be brought into contact at one place. Therefore, even if a force is applied during the rising of the lock member, the lock member can be raised against the force.

In the parking management device of the present invention, the more the lock member stands, the more the angle of the tangent between the connection shaft and the connection hole becomes parallel to the direction of expansion and contraction of the cylinder shaft.

With this configuration, the angle of the tangent between the connection shaft and the connection hole becomes parallel to the direction of expansion and contraction of the cylinder shaft as the lock member stands, so that the force for tilting the lock member is reduced. Is attenuated as the lock member stands and is transmitted to the driving means, making it difficult to fall down. In addition, the connection hole is formed in a substantially rectangular shape or a substantially triangular shape, which makes it very easy to design and manufacture.

[0025] In the parking management device of the present invention, the connection hole may be:
When the lock member is driven by the driving means, the contact portion with the connection shaft is formed linearly, and the more the contact portion and the direction of expansion and contraction of the cylinder shaft become parallel, the more the lock becomes. The member stands.

With this configuration, the more the contact portion and the direction of expansion and contraction of the cylinder shaft become parallel, the more the lock member rises. Therefore, the force for tilting the lock member is attenuated as the lock member rises. And transmitted to the drive means, making it difficult to defeat.

Moreover, when the lock member is driven by the drive means, the contact portion with the connection shaft is formed in a straight line, so that the lock member is located at any position within the inverted angle range. Also, the connecting shaft and the connecting hole can be brought into contact at one place. Therefore,
Even if a force is applied during the rising of the lock member, the lock member can stand up against the force.

In the parking management device according to the present invention, the lock member is set up as the cylinder shaft is extended, and the support surface is formed on an inclined surface in which the cylinder shaft side is separated from the lock shaft. The connecting shaft is not held when the cylinder shaft is most retracted.

With this configuration, the holding of the connecting shaft by the support surface is released when the lock member is tilted, so that a light force is applied to the lock member just as when there is no support surface. The lock member can be set up against the force of the compressed gas or the compressed liquid that suppresses the cylinder shaft.

According to the parking management device of the present invention, the connecting hole is formed in a shape that allows the lock member to be further rotated from the state where the cylinder shaft is most extended, and the connecting hole is opened when the rotation is performed. A stopper is provided in the rotation direction so that the connection shaft does not abut.

With this configuration, the lock member can be rotated without applying a force to the cylinder shaft. Therefore, the cylinder shaft can be moved from its upper stopping point to its lower stopping point in order to invert the lock member within a predetermined inversion angle range. Moreover, if the cylinder shaft is set to be in the most extended state when it comes into contact with the stopper, it is necessary to adjust the position between the cylinder shaft and the stopper, but such adjustment is not necessary. .

[0032] In the parking management device of the present invention, the connection hole may be:
The connection shaft is opened so that the connection shaft can move to a position where the holding of the connection shaft by the support surface can be released.

According to this structure, since the connection hole is formed in a shape in which the connection shaft can be moved to a position where the holding of the connection shaft by the support surface can be released, the connection shaft is moved to the release position. Thus, the lock member can be set up against the force of the compressed gas or the compressed liquid that suppresses the cylinder shaft by applying only a light force to the lock member.

[0034] The parking management device of the present invention is provided with a roller rotatably disposed around the connection shaft as an axis, and the roller comes into contact with a support surface.

With this configuration, for example, when the connecting shaft is in direct contact with the support surface, the force acting on the contact portion with the support surface or the force acting on the contact portion with the connection hole. The force that rotates it acts on the connecting shaft,
It is possible that a force in the direction perpendicular to the driving direction of the connecting shaft about the connecting shaft may act on the driving means, but it is necessary to surely prevent such a force from acting on the driving means. Can be. In particular, when a cylinder is used as the driving means, even if the above-mentioned force acts in a state where the cylinder shaft is extended, breakage of the cylinder can be effectively suppressed.

[0036] The parking management device of the present invention includes a housing,
A lock shaft rotatably supported by the housing, a lock member fixed to the lock shaft and inverted in response to rotation of the lock shaft, and a cylinder that rotationally drives the lock member by moving the cylinder shaft. , With a through hole,
A block disposed below the housing,
A drain hole is opened at a position corresponding to the through hole on the bottom surface of the housing.

With this configuration, the cylinder is used as a means for driving the lock member around the lock shaft, and mud and water that have entered the housing can be discharged to the outside from the drain groove. In particular, since the through holes of the block correspond to the drain grooves and the rainwater drain holes are formed below the drain grooves, rainwater and mud can be drained efficiently and stably for a long period of time. In particular,
In a parking lot using this parking management device, since it is general to paving because a coil or the like for detecting a vehicle is buried, mud is less likely to enter the housing, and such a small drainage The hole can sufficiently maintain the performance.

The parking management device of the present invention comprises the above-described parking management device, a tank for supplying a compressed gas or a compressed liquid, and a plurality of cylinders of the plurality of parking management devices from the front or rear of the cylinder axis. A plurality of switches for supplying the compressed gas or the compressed liquid; and control means for individually outputting an electrical control signal to the plurality of switches. When there is no signal, the tank is communicated with the front of the cylinder shaft by mechanical force.

If this configuration is adopted, when no electrical control signal is input, the switching device causes the tank to communicate with the front of the cylinder shaft by mechanical force. In the case where the lock member has been lost, the control signal is not output, so that the lock member can be returned to the home position.

Therefore, when a conventional stopper mechanism or the like is used, a device for applying a special force for releasing the stopper mechanism even at the time of a power failure is separately required, but such a device is added. The same effect can be obtained without performing.

There is no need to provide a drainage facility in the parking lot for draining water that has entered the sewage. In particular, the lock member 1
Since the air cylinder 34 is used to drive the motors 3 and 14, unlike the case where the motor is driven by the electric motor, the air cylinder 34 operates normally even if it is submerged, and operates without any problem if the period is not long. Therefore, such a simple drainage system can sufficiently withstand practical use.

FIG. 6 is a system configuration diagram showing a parking management system according to Embodiment 1 of the present invention. FIG.
1 is a perspective view of a parking lot showing an installation state of a parking management system.

The parking management system supplies a plurality of individual units 58 provided for each of the parking areas 57 partitioned according to the size in which the automobile can be parked, and supplies electric power from a commercial power supply 59 to the plurality of individual units 58. A power distribution line 60, a pressure distribution tube 61 for supplying pressurized air to the plurality of individual units 58, a pressure tank 62 connected to one end of the pressure distribution tube 61, and a tank filled with compressed air; When it is connected to the distribution line 60 and the internal pressure of the pressurized tank 62 becomes lower than a predetermined pressure (for example, 5 kgw / m ² ), the air is compressed by electric power and supplied to the pressurized tank 62, thereby increasing the pressure. A compressor 63 for maintaining the pressure in the tank 62 at or above the predetermined pressure.

Each of the individual units 58 is buried at the entrance of the car in the parking area 57, and the parking management device 64 in which the lock members 13 and 14 are inverted by the air cylinder 34.
And an air switch 65 as a switch connected to the air cylinder 34 and the pressure distribution tube 61 to inject compressed air supplied from the pressure distribution tube 61 into the air cylinder 34 from the front or rear thereof. 57
A control signal is sent to the air switch 65 in response to vehicle detection by the multiple winding coil 66, which is erected at a position close to each parking area 57 and a multiple winding coil 66 buried near the back side of the vehicle. It comprises a control circuit 67 as a control means for outputting, and a settlement unit 69 having a settlement circuit 68 for notifying the control circuit 67 of a settlement-completed signal when a parking fee is paid by inserting money. Note that, instead of the multiple winding coil, an optical light sensor in which a light emitting element and a light receiving element are combined may be used to detect light blocking or reflection by an automobile.

The settlement unit 69 or the settlement circuit 68 may be provided in common in a plurality of parking areas 57. In this case, it is sufficient that the user inputs the number of the parking area 57 in which the vehicle is parked before the money is input, thereby specifying which parking area 57 the settlement is for.

Further, behind each parking area 57, a pole 70 is erected to prevent the vehicle from backing further.
Further, the vehicle area 57 is provided on both sides of each vehicle area 57.
A bar 71 is installed to prevent the vehicle from escaping from the side of the vehicle. Instead of the pole 70, a wheel stopper may be provided in the parking area 57.

As shown in a sectional view of FIG. 4, the air switch 65 includes a substantially rectangular housing 72, a cylinder hole 73 formed on one side in the longitudinal direction of the housing 72, and a housing 72. The three through holes 74, 75, 76 opened from one short side of the short side 72 to the cylinder hole 73, and the other through side of the short side of the housing 72 communicate with the cylinder hole 73. and,
Two through holes 77, 78 opened to communicate between adjacent sets of the three through holes 74, 75, 76, and four Os are provided in the cylinder hole 73.
When a control signal from the control circuit 67 is input, the switching cylinder 80 on which the ring 79 is disposed, the spring 81 disposed between the other long side surface of the housing 72 and the switching cylinder 80, A switch 82 for moving the switching cylinder 80 to the rear side of the cylinder hole 73 against the force of the spring 81. In addition, you may use what is called a 3 port 1 solenoid type air switch, a 4 port 2 solenoid type air switch, etc. other than this.

Then, as shown in FIG. 4, the pressure distribution tube 61 is connected to a through hole 75 in the middle of the three rows. The switch-side through-hole 78 of the two through-holes is connected to the upper chamber through-hole 42 of the cylinder 34, and the lower chamber through-hole 43 is connected to the other through-hole 77. Therefore, when there is no control signal, the switching cylinder 80 is moved to the switch 82 by the force of the spring 81, so that the O-ring 79 provided in the switching cylinder 80 connects the through hole 75 and the upper chamber through hole 42. In addition, the through hole 74 and the lower chamber through hole 43 communicate with each other. Therefore,
When compressed air is injected into the through hole 75, the pressure of the compressed air pushes the cylinder shaft 37 rearward,
The cylinder shaft 37 is in the state of being inserted most inside the housing 35 of the cylinder 34.

When an automobile is detected by the multiple winding coil 66 and a control signal is input from the control circuit 67, the switching cylinder 80 moves to the spring 81 side. By
The through hole 75 communicates with the lower chamber through hole 43, and the through hole 76 communicates with the upper chamber through hole. Therefore, when the compressed air is injected into the through hole 75, the cylinder shaft 37 is pushed forward by the pressure of the compressed air, and the cylinder shaft 37 projects from the housing 35 of the cylinder 34 most.

As described above, when there is no control signal, the cylinder shaft 37 is set to the retracted state, and when the cylinder shaft 37 is retracted, the lock members 13 and 14 fall down. With this setting, for example, in the event of a power failure or the like, there is no control signal and the lock members 13 and 14 can be automatically tilted. Therefore, at the time of a power failure, the regulation by the lock members 13 and 14 for the parked vehicle can be automatically released.

Next, the operation of the parking management system having the above configuration will be described.

FIG. 8 is an operation explanatory diagram showing the operation of the parking management device in FIG.

When the compressor 63 is operated to fill the pressurized tank 62 with the compressed air compressed to a predetermined pressure, the through-holes 75 and the through-holes 78 communicate with each other in the air changers 65. The cylinder shaft 37 is the cylinder 3
4 is located at the lowest home position. Therefore, the drive plate hole 53 is in the lowest position by the connecting shaft 51 attached to the tip of the cylinder shaft 37, and the lock members 13, 14 are also held in the down state (FIG. 8A).

In this embodiment, the cylinder shaft 37 is in the most retracted state, that is, the lock member 1
In a state in which the lock members 13 and 14 are in contact with the ground by falling down, the roller 50 and the inclined plate 33 are separated from each other in order to facilitate lifting the lock members 13 and 14 by hand for a reason described later.

When the vehicle enters the parking area 57 with the lock members 13 and 14 lowered as described above, the control circuit 67 detects that the vehicle has approached based on a signal from the multiple winding coil 66. And output a control signal. The control circuit 67 is, for example, a multi-winding coil 6
6, a capacitor (not shown) may be connected in parallel, and the entry of the vehicle may be detected based on a change in the oscillation frequency of the parallel circuit.

The air switch 65 operates the switch 82 in response to the input of the control signal to move the switching cylinder 80 to the far side of the cylinder hole 73. Thereby, the through hole 77 is newly communicated with the through hole 75 and the cylinder shaft 3
Compressed air is injected behind 7.

When the cylinder shaft 37 moves forward in response to the injection of the compressed air, the connecting shaft 51 pushes the drive plate 15, so that the lock members 13 and 14 also rotate and start to stand. When the roller 50 comes into contact with the inclined plate 33 as shown in FIG. 8B, the connecting shaft 51 then moves up along the inclined plate 33.

Finally, as shown in FIG. 8C, the connecting shaft 51 is stopped at a position where the cylinder shaft 37 is completely extended by the pressure injected into the cylinder 34, and the connecting shaft 51 The lock members 13 and 14 stop while the drive plate 15 is supported.

FIG. 9 is a perspective view illustrating a state where a vehicle (indicated by a dashed line) stops in parking area 57. By raising the lock members 13 and 14 in this manner,
The four sides of the vehicle parked in the parking area 57 can be surrounded by poles 70 at the rear of the vehicle, bars 71 on both sides of the vehicle, and lock members 13 and 14 to prevent the vehicle from escaping in this state. be able to.

The pressurized tank 62 has a capacity capable of maintaining the above-mentioned predetermined pressure even when the compressed air is injected into the plurality of cylinders 34 simultaneously. do it.

When returning to the parking lot, the user of the parking lot enters a fee corresponding to the usage time into the settlement unit 69. When a predetermined parking fee is charged, the settlement circuit 68 notifies the settlement signal to the control circuit 67, and the control circuit 67 stops outputting the control signal. Further, the air switch 65 stops the switch 82, returns the switching cylinder 80 to a position short of the cylinder hole 73, and the through hole 78 communicates with the through hole 75. Accordingly, the compressed air is injected into the front of the cylinder shaft 37 and moves rearward, the lock members 13 and 14 are lowered, and return to the state of FIG.
The user can drive the car in this state and leave the parking lot.

With the above operation, when the car is parked in the parking area 57, the lock members 13, 14 are raised to cut off the escape route, and when a predetermined fee is paid, the lock members 13, 14 are lowered. You can leave.

Next, detailed operations and effects of the roller 50 moving on the inclined plate 33 when the connecting shaft 51 is moved by the cylinder shaft 37 and the shape and arrangement posture of the connecting hole 53 will be described in detail. .

FIG. 10 is an explanatory view showing a minimum configuration when the lock members 13 and 14 are raised and lowered using the air cylinder 34. In this configuration, the connection hole 53 is formed as a hole having the same diameter as the connection shaft 51.

As described above, when the connecting hole 53 is formed to have the same diameter as the connecting shaft 51, when a pressing force in the direction of arrow A is applied to the lock members 13 and 14, the drive is performed about the lock shaft 12 serving as a fulcrum. The plate 15 also rotates, and a force (F = Fo) larger than the force applied to the lock members 13 and 14 acts on the connecting shaft 51 based on the principle of leverage. Therefore, the cylinder shaft 37 can be pushed with a relatively small force against the pressure of the compressed air injected into the cylinder 34. As a result, for immoral users, the locking members 13, 14
To escape without paying a fee.

Therefore, as shown in FIG.
Is larger than the connecting shaft 51 and has a substantially rectangular long hole shape, and the connecting shaft 5 is formed by the inclined plate 33 and the roller 50.
1 is raised above the lower side of the connection hole 53. With such a positional relationship, the connecting shaft 51 and the connecting hole 53 are in contact with each other at one place, and the connecting shaft 51 supports the drive plate 15 in this state.

When the lock members 13 and 14 are pushed down in such a state, the same force as the above Fo is applied to the contact point between the connection shaft 51 and the connection hole 53. Since the shaft 51 can move inside the connection hole 53 along the upper side thereof, only the force of the normal component perpendicular to the tangent acts on the connection shaft 51. Therefore, if the angle between the line segment connecting the lock shaft 12 and the contact point and the long side of the connection hole 53 is θ1, the force F for pushing the cylinder shaft 37 becomes small as shown in the following equation 1. The cylinder shaft 37 is hard to be pushed.

F = Fo × (cos θ1) ² Equation 1

Note that, as shown in FIG.
Θ between the line segment connecting the contact and the long side of the connection hole 53
If 1 is 0 degrees, Fo itself acts on the cylinder shaft 37 even if the connection shaft 51 and the connection hole 53 are in contact at one place. This is clear from equation (1). Therefore, in order to reduce the force acting on the cylinder shaft 37, the angle θ1 must be larger than 0 degree. Moreover, as the angle is increased, the force for pushing the cylinder shaft 37 is drastically reduced (decreased by (cos θ) ² ). Therefore, it is preferable that the angle θ1 be as large as possible.

Further, the connection hole 53 having a long hole shape has another meaning. When the effect of suppressing the pressing force is expected, the roller 50 needs to be constantly kept in contact with the inclined plate 33 during the period when the lock shaft 12 is driven from the falling position to the standing position. If the roller 50 is separated from the inclined plate 33 on the way, a state similar to that shown in FIG. 10 is generated. Therefore, when a pressing force is applied during driving, the locking member 13 14, the lock members 13 and 14 cannot easily be correctly set up. In addition, in consideration of ease of production, the inclined plate 33 is desired to be formed in a plane.

FIG. 13 shows the locus of the roller 50, the connecting shaft 51, and the connecting hole 53 based on such conditions. Roller 50
Moves on the inclined plate 33, so that when the flat inclined plate 33 is used, the connecting shaft 51 also moves linearly in parallel with the inclined plate 33. Therefore, the distance between the lock shaft 12 and the connection shaft 51 becomes shorter or longer according to the position of the connection shaft 51.

Therefore, the connecting hole 53 must be formed to have a length that is in contact with the connecting shaft 51 at least at one position in at least the fluctuation range 83 of the connecting shaft 51. That is, the connection hole 53 is formed in a long hole shape such that the length of the connection hole 53 in the direction along the line connecting the lock shaft 12 and the connection shaft 51 is longer than the fluctuation range 83 of the connection shaft 51. There is a need. Note that the inclined plate 33 itself is the lock shaft 12.
In the case where the connecting hole 53 has a plane shape along an arc centered at the center, there is no need to make the connecting hole 53 a long hole shape.

When the connection hole 53 is formed in a substantially rectangular long hole shape expecting the above two effects, the connection shaft 5
As the distance between the lock shaft 112 and the lock shaft 112 becomes shorter, a larger force is applied to the connection shaft 51.
Since the angle between the line connecting the lock shaft 12 and the contact point and the tangent increases, as shown in FIG. 14, depending on the position of the connection shaft 51 in the connection hole 53, the lock member 13,
Basically, there is little difference in the force acting on the connecting shaft 51 when the button 14 is pushed down.

However, as shown in FIG. 15, when the lock members 13 and 14 are set up when the cylinder shaft 37 is pushed out, the lock members 13 and 14 are set up when the lock members 13 and 14 are set up. , 14 and the tangent to the connecting hole 53 of the connecting shaft 51 and the fixed shaft 4
Since the line connecting the shaft 4 and the connecting shaft 51 can be made nearly parallel, the component of the force for pushing the cylinder shaft 37 is reduced. Thereby, the standing lock member 1
3, 14 can be made harder to push down.

Even if the connecting hole 53 is formed in an arc-shaped long hole centered on the lock shaft 12 side as shown in FIG. 16, the opposite side to the lock shaft 12 as shown in FIG. May be formed in an arc-shaped long hole centered at.

In the case where the connecting hole 53 is formed in an arc-shaped long hole centered on the lock shaft 12 side, the lock member 13,
It is difficult to push down when the stand 14 is set up or down, and it is difficult to push down as a whole regardless of the positions of the lock members 13 and 14.

Conversely, when the connecting hole 53 is formed in an arc-shaped long hole centered on the side opposite to the lock shaft 12, the more the locking members 13, 14 are in a more inclined state, the more the locking members 13, 14 become. 14 can be more easily pushed down. Thereby, for example, even if the vehicle is moved in a state where the lock members 13 and 14 are not completely collapsed and the lock members 13 and 14 collide with the vehicle, the collision can be mitigated. It can reduce the damage of the parking management device and the car.

Next, another advantage of forming the connecting hole 53 in a long hole shape will be described.

In such a setting, as shown in FIG. 18, when the lock members 13 and 14 which are lying down are to be lifted in the direction of arrow B, the connecting shaft 51 is connected to the lower side surface of the connecting hole 53 and, consequently, to the cylinder 34 side. I go up the side,
The connecting shaft 51 rotates around the fixed shaft 44 and lifts. Thus, the roller 50 is separated from the inclined plate 33. This state is the same as the state shown in FIG. Therefore, the locking members 13 and 14 can be further lifted with a relatively light force by the leverage principle. Therefore, even if a foot or an object is accidentally pinched between the lock members 13 and 14 and the ground, the feet or the object can be easily pulled out by lifting the lock members 13 and 14.

Note that in such a lifting operation,
The angle θ2 between the tangent line between the connecting shaft 51 and the connecting hole 53 and the inclined plate 33 may be an obtuse angle of 90 degrees or more. If the angle θ2 is an acute angle, by lifting the lock members 13 and 14, a force is generated to press the roller 50 and the connecting shaft 51 between the tangent and the inclined plate 33. As a result, the lock members 13 and 14 cannot be lifted until the force becomes larger than the frictional force between the roller 50 and the inclined plate 33 or the like. This is because it requires great power.

In the conventional parking management device using the air cylinder 34, a lock mechanism is provided separately from the driving mechanism by the air cylinder 34 in order to prevent the vehicle from escaping. In the case where such a lock mechanism is provided, the lock members 13 and 14 that have fallen down with a small force as in the present invention cannot be appropriately lifted.

Further, even if a person or a car collides with the standing lock members 13 and 14 from the direction of arrow C in FIG.
In this embodiment, the force is absorbed by the stopper 25. At this time, the connecting hole 5 is set so as not to apply a force to the extended cylinder shaft 37.
3 may be extended further to a position closer to the lock shaft 37 than the position of the connecting shaft 51 when the lock members 13 and 14 are upright. Thus, it is possible to prevent the cylinder from applying a force that bends or pulls the cylinder, thereby preventing the cylinder 34 from being damaged.

As shown in FIG. 19, when the drive plate 15 is rotated until it comes into contact with the shock absorbing material 31 of the stopper 25, the connecting shaft 51 can rotate around the fixed shaft 44 at the same radius. The connection hole 53 may be opened up to the position.

As is apparent from the above description, basically, the function of the connection hole 53 can be sufficiently exhibited if the connection hole 53 has a substantially rectangular long hole shape.

However, in this embodiment, the connection hole 53 is formed in a substantially triangular shape. In other words, the lower side (the side facing the lock shaft 12 across the upper side) is closer to the lock shaft 12 than the upper side (side closest to the lock shaft 12) of the connection hole 53.
It is formed so that the angle with respect to the line connecting the shaft and the connecting shaft 51 becomes large. Thereby, the lock members 13, 1
4 can be smoothly separated from the inclined plate 33 by lifting the lock member 1.
When a force other than the force from the cylinder shaft 37 is applied to the cylinders 3 and 14, unnecessary force is prevented from acting on the cylinder 34.

As apparent from the above description, in this specification, contact at one place does not mean that the contact state between the connection shaft 51 and the connection hole 53 is limited to point contact. For example, even with the configuration of the above embodiment, the connection shaft 51 and the drive plate 15
Taking into account the thickness, it is at least in line contact.

Furthermore, if the effect of the present invention is expected, it is naturally most effective to make contact at one place, but the connecting shaft 51 and the connecting hole 53 may be provided at a plurality of places. Absent. However, in this case, at least, the resultant force of the forces acting on the plurality of contact points is smaller than the force acting on the connecting shaft 51 when the connecting hole 53 is formed to have the same diameter as the connecting shaft 51. What is necessary is just to reduce the contact part between the connection shaft 51 and the connection hole 53.
