Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a parking apparatus, and more particularly, to a parking apparatus configured to effectively prevent unauthorized leaving of a parked vehicle.
[0002]
[Prior art]
A locking type parking device that locks a vehicle parked at a predetermined position as one of parking devices with a member called a flap plate that rotates around an axis provided on one side, and pays a fee corresponding to the parking time. There is. This type of parking device can be installed in a short time with fewer people by placing a parking mechanism on a flat ground, so it can be installed at a lower cost than a three-dimensional parking device, and as a result, as an effective means of using vacant land recently. Widely used.
[0003]
The outline of the configuration of the conventional apparatus will be described with reference to FIG. 6 showing the use state of the apparatus of the present invention. The base portion 50 arranged in the parking space is provided with a flap plate 52 that swings around a shaft 51. When the entering vehicle is detected, the flap plate 52 stands up to prevent the vehicle from leaving, and the flap plate 52 is lowered by charging a fee corresponding to the parking time, thereby allowing the vehicle to leave.
[0004]
[Problems to be solved by the invention]
The parking device having the above-described configuration is effective for a vehicle having a small distance (road clearance) between the bottom surface of the vehicle body and the road surface, such as a passenger car or a light vehicle, but is called a recreational vehicle (commonly referred to as RV) as illustrated. With a large clearance and a four-wheel drive vehicle, it is almost impossible to prevent unauthorized exit. That is, in such a vehicle, even if the flap plate 52 stands, a considerable space is generated between the upper end of the flap plate and the bottom surface of the vehicle, and the wheels that are locked to the flap plate 52 are still four-wheel drive. Since all the other wheels exhibit driving force, the wheel locked to the flap plate 52 can easily get over the flap plate 52, and can easily leave the wheel.
[0005]
Improper exit of the vehicle not only results in a parking fee being unpaid, but also a large load is applied to the flap plate 52 that stands when the vehicle exits. It will cause undue damage.
From the viewpoint of preventing unauthorized exit, it is conceivable to increase the width of the flap plate 52 so that the flap plate contacts the bottom of the vehicle even when the vehicle has a large load clearance. However, in this configuration, it is necessary to increase the driving force for raising and lowering the flap plate, but on the four-wheel drive vehicle etc., it does not become a large blocking force, and the moment arm is increased by increasing the width of the flap plate, It is highly possible that the damage to the mechanism part during illegal evacuation is likely to increase rather than solving the problem.
[0006]
[Means for Solving the Problems]
The present invention is a parking apparatus configured in view of the above-described problems, and eliminates the method of swinging the flap plate around a rotating shaft, and locks at least a part of the wheels of a parked vehicle. Is a parking device configured to prevent unauthorized exit of the parked vehicle, a device body fixed to the ground portion, a lifting member that locks the wheels of the parked vehicle and moves up and down with respect to the device body, In a lock type parking apparatus comprising an elevating mechanism interposed between the elevating member and the apparatus main body and elevating the elevating member and a drive device for operating the elevating mechanism, of the front and rear side edges of the elevating member Further, means for idling the wheel by absorbing the rotation of the wheel, such as a roller, is disposed at least on the side edge on the side where the wheel of the exiting vehicle abuts, and the hand for idling the wheel on the apparatus main body installation surface side Is disposed a stopper for stopping the operations, and characterized in that during the lifting member descends a locking parking apparatus characterized by being configured to prevent slipping of the wheels of the exit the vehicle by preventing the operation of the idle means To do.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
A drive device is disposed in the apparatus main body, and a drive arm is connected to the drive device. The drive arm is provided with a follower arm arranged so as to intersect the drive arm by a lift shaft, and a lift member is attached to the upper end of the drive arm and the follower arm.
[0008]
The lower part of the drive arm moves in a horizontal direction along a guide groove or a guide slot formed in the apparatus body in accordance with the forward / backward movement of a drive member such as a hydraulic cylinder. This moving operation is transmitted to the driven arm via the lifting shaft. In other words, when the drive arm rotates in the standing direction, the lift arm attached to the tip of each of the driven and driven arms rises by the same operation of the driven arm. On the other hand, when the drive arm operates in the descending direction, the follower arm also performs the same operation, thereby lowering the lifting plate.

On the other hand, reference numeral 9 denotes a driven arm, which is formed of a relatively thick high-strength metal material like the drive arm 4. A pair of the follower arms 9 is also arranged as indicated by reference numerals 9a and 9b in FIGS. These driven arms 9a and 9b are arranged so as to intersect the drive arms 4a and 4b by a shaft body 10 (hereinafter referred to as “moving shaft”). Unlike the drive arm, a shaft body 11 (hereinafter referred to as “fixed shaft”) that is fixedly disposed at a predetermined position of the apparatus main body 1 is inserted and disposed at the lower end portions of the driven arms 9a and 9b. .
[0013]
Of the arms 4 and 9, first, the upper ends of the drive arms 4 a and 4 b are connected to the lifting member 2 via a shaft body 12 (hereinafter referred to as “fixed shaft”) fixedly disposed on the lifting member 2. doing. On the other hand, the shaft body 13 is inserted into the distal ends of the driven arms 9a and 9b, and both ends of the shaft body 13 are inserted into guide holes 14 which are elongated holes formed in the elevating member 2, and thereby the guide holes 14 is configured to be slidable in the horizontal direction along the axis 14 (hereinafter, the shaft body 13 is referred to as a “moving axis”). The elevating member 2 is configured to be supported by the drive arm 4 and the driven arm 9 that are arranged to intersect with each other.
[0014]
Reference numerals 15 and 16 are auxiliary members that are interposed between the two members at both ends of the elevating member 2 and the apparatus main body 1, and each of the elevating members 2 is moved up and down by the operation of the drive arm 4 and the driven arm 9. It is configured to operate in accordance with the lifting operation and to reinforce the strength of the entire apparatus when the lifting member 2 is lifted. The structure of the auxiliary member 15 will be mainly described by way of example. The upper end of the auxiliary member 15 is swingably attached to the lifting member 2 by the fixed shaft 17, and the lower end is a long hole formed in the apparatus main body 1. A moving shaft 30 that moves in the horizontal direction along a certain guide hole 18 is inserted.
[0015]
The auxiliary member 16 also has the same configuration. Reference numeral 19 denotes a fixed shaft on the lifting member 2 side, and 20 denotes a moving shaft that slides along the guide hole 21 of the apparatus main body.
[0016]
Next, in FIG. 2, reference numeral 22 denotes a sensor (pressure-sensitive sensor) disposed at the upper end of the elevating member 2, and this sensor or a pressure-sensitive material such as a plate connected to the sensor is connected to the bottom surface of the vehicle. It detects contact. 2 and 3 is a cover, and the cover 23 is formed as a bellows such as rubber. The upper end is attached to the elevating member 2 and the other end is fixed to the ground side. ing. By attaching the cover 23, the internal lifting mechanism and the like are protected from rain wind, dust and the like, so that reliable operation of the apparatus is ensured. In addition, a fluorescent paint or the like may be applied to the bellows portion to increase the visibility of the entire apparatus, or a specific commercial message may be used as an advertising means.
[0017]
Next, the operation state of the apparatus will be described. First, when the vehicle is not parked in the parking space, as shown in FIGS. 1 and 3, the elevating member 2 is disposed at the lowest position indicated by reference numeral 2 '. Reference numerals 4 ', 9', 15 ', and 16' in the figure indicate the driving arm, the driven arm, and the auxiliary member at the lowest position, respectively. In this state, when the approaching vehicle moves in the direction of the arrow in FIG. 3 and stops at a predetermined position, the approaching and parking of the vehicle are detected by a sensor (not shown) such as a photoelectric tube. In this case, since the sensor 22 is OFF, no signal is emitted from the sensor 22 even if the wheel passes the sensor 22.
[0018]
The sensor 22 is turned on when a vehicle parking signal is issued from a sensor (not shown). In addition, the hydraulic cylinder 7 of the parking device is actuated by this signal, the drive shaft 5 is pushed out in the X1 direction in FIG. 1, and the lower end of the drive arm 4 is also moved in the X1 direction by the actuation of the drive shaft 5. On the other hand, since the lower end of the driven arm 9 connected to the drive arm 4 via the moving shaft 10 is disposed at a predetermined position by the fixed shaft 11, both the arms 4, 9 are moved by the movement of the drive shaft 5 to the fixed shaft 11. Stands up and the elevating member 2 rises in response to this standing up. In this case, the relative displacement between the upper ends of the arms 4 and 9 and the elevating member 2 is absorbed by the movement shaft 13 on the driven arm 9 side sliding along the guide hole 14.
[0019]
On the other hand, the auxiliary members 15 and 16 at both ends stand up as the elevating member 2 is raised. In this case, since each auxiliary member 15, 16 is attached to the fixed shafts 17, 19 on the lifting member 2 side, the lower end moving shafts 30, 20 are relative to the standing movement, and the lower end moving shafts 30, 20 are guide holes 18 of the apparatus main body 1. , 21 is absorbed by sliding.
[0020]
When the sensor 22 provided on the elevating member 2 comes into contact with the bottom surface of the vehicle, the drive of the hydraulic cylinder 7 is stopped by this contact signal, and the elevating member 2 is locked at this raised position. In this case, since the highest position of the elevating member 2 is set to approximately the same height (for example, about 35 cm) as the load clearance of the four-wheel drive vehicle having a large load clearance, the four-wheel drive vehicle is parked. In addition, the auxiliary members 15 and 16 are also in the most upright position (see FIG. 1). Even if a large load is applied in the lateral direction of the device (in the direction of the arrow in FIG. 2) in order to move the vehicle for illegal leaving in such a state, the driven and driven arms 4 and 9 and the auxiliary members 15 and 16 are used. In order to keep the whole strong, the vehicle cannot be illegally exited. In addition, even if the climbing device is overridden and the vehicle is illegally evacuated, the auxiliary members 15 and 16 are also in the highest standing position, so the weight of the vehicle body is also supported by the auxiliary member. There is no risk of being destroyed. In the case of a passenger car having a small load clearance, the elevating member 2 stops at a lower position, and the auxiliary members 15 and 16 are not useful for supporting the load in the vertical direction. Even if the passenger leaves the vehicle illegally, the weight of the vehicle is small, so that the weight of the vehicle can be sufficiently held only by the driving and driven arms 4 and 9.
[0021]
On the other hand, when a predetermined parking fee is charged to leave the vehicle, the hydraulic cylinder 7 returns to the Y1 direction of FIG. 1 by an input signal by a predetermined fee, and the drive arm 4 and the driven arm 9 correspond to this operation. The auxiliary member 15 and 16 are also driven by this operation, and the elevating member 2 is lowered to the lowest position indicated by reference numeral 2 'in FIGS. The sensor 22 is turned off by the input signal, and the off state is maintained until the next vehicle parking. By the way, this sensor 22 is kept in the off state. If the sensor 22 is in the on state, this pressure sensitive signal is processed as a contact signal on the bottom surface of the vehicle when the vehicle enters, and this prevents the device from rising. Because.
[0022]
Figure 6 is shows the arrangement of locking the parking apparatus shown in above, each code PM1 and PM2 show the parking system. Usually, the parking device is often one of those indicated by PM1, and this is sufficient for locking the vehicle C that has entered the car stop 24, but another parking device PM2 is also provided behind the parked vehicle. If it is placed, unauthorized exit of the vehicle is almost 100% impossible. In addition, in the case of a vehicle having a short overall vehicle body, such as a light vehicle, even if the vehicle is parked in front of the parking device PM1, the vehicle is almost stored in the parking space. If another parking device PM2 is arranged in this way, this kind of illegal parking can also be prevented. In particular, if the parking device PM2 is placed in a conspicuous color such as yellow, or if the cover 23 is also conspicuously colored, it will be clear that the vehicle has not been unlocked. It is possible to prevent accidents such as the vehicle being damaged by trying to leave accidentally or by using the device before the device is completely lowered. Further, if a commercial message is described in the cover of the standing apparatus as described above, an advertising effect can be expected.
[0023]
FIG. 4 shows a second embodiment of the present invention. In this embodiment, the apparatus is simplified and the same members are denoted by the same reference numerals. In this apparatus, first, the auxiliary members 15 and 16 shown in the first embodiment are eliminated. Further, the entire width of the elevating member 2 is shortened to about 2/3 that of the above embodiment, and as a result, the hydraulic cylinder 7 is located outside the lower space of the elevating member 2. A relatively long link member 8 </ b> A is interposed between the drive shaft 5 and the hydraulic cylinder 7. Although this device is not as strong as the above embodiment in terms of strength, it can be constructed at low cost because the entire device is simplified. Further, only the parking device PM2 behind the parked vehicle shown in FIG. 6 may be configured as this device.
[0024]
FIG. 5 shows a third embodiment. In this embodiment, a wheel rotation absorbing means such as a roller 25 is provided on at least a side edge of the both side edges of the elevating member 2 that comes into contact with the locked wheel. In addition, a belt etc. can be considered as another structure of a means to absorb rotation of a wheel. Hereinafter, the roller 25 will be described as an example. If the parking device is in the raised position and tries to leave the vehicle illegally, even if the wheel locked to the parking device is a driving wheel, the driving wheel contacts the side edge. the rotational force of the O Ri drive wheels is will be idle is spent to rotate the roller 25, the device driving wheels becomes difficult to overcome.
[0025]
When the parking fee is paid and the elevating member 2 reaches the lowered position, the roller 25 comes into pressure contact with a stopper 26 installed on the ground portion, and its rotation is suppressed. For this reason, the leaving vehicle gets over the lifting member 2 without any problem. If the stopper 26 is made of a rubber material, it can come into contact with the roller 25 with a high coefficient of friction, and it is optimal because it absorbs some errors in the lowered position of the elevating member 2 due to its deformation. It is.
[0026]
In the above embodiment, the drive mechanism for operating the device has been described as an example of a hydraulic cylinder, but it is not intended to limit the drive mechanism to a hydraulic cylinder, but by being driven to rotate by another cylinder device such as an air cylinder, or an electric motor, Various drive mechanisms such as a screw rod configured to move forward and backward in the same direction as the moving direction of the cylinder rod can be used.
[0027]
【The invention's effect】
As described in detail above, the present invention comprises an apparatus main body, an elevating mechanism provided in the apparatus main body, and an elevating member that elevates in the vertical direction by the elevating mechanism. By disposing a means such as a roller that absorbs the rotation of the wheel at least on the side of the side edge of the vehicle that comes in contact with the wheel of the vehicle that leaves the vehicle, the wheel of the vehicle that is about to leave illegally is idled to prevent unauthorized exit. When the lifting / lowering member descends and the vehicle exits properly, the means for absorbing the rotation of the wheel is blocked by the stopper that is disposed to prevent the vehicle from leaving the vehicle. As a result, it is possible to realize both the prevention of unauthorized leaving of the vehicle and the prevention of the occurrence of trouble when leaving properly.
