Description

  The present invention relates to a car stop device, and more particularly, to a car stop device that is installed in an unmanned parking lot or the like to prevent unauthorized vehicle exit.

  Conventionally, as a vehicle stopping device installed in an unmanned parking lot or the like, a vehicle locking device that prevents unauthorized vehicle exit and a lifting / lowering mechanism that lifts and lowers the vehicle locking device have been used (Patent Document 1). The vehicle lock device has a lock plate that comes into contact with the bottom of the vehicle. The lifting mechanism is a pneumatic actuator including an air switch, a compressor, and an air cylinder. That is, by controlling the supply of air to the air cylinder and the discharge of air from the air cylinder, the lock plate is raised and lowered. Here, the vehicle lock device also includes a slide elevating member and an inclined plate as a structure for raising and lowering the lock plate.

JP-A-2005-36491

However, in the case of the vehicle stopper according to the above prior art, there are various problems as follows due to the connection structure between the vehicle locking device and the lifting mechanism and the structure of the lifting mechanism itself.
(1) Since the elevating mechanism is pneumatic, when an external force is applied to the lock plate from above, the air is compressed and the lock plate is easily lowered. For this reason, it was not possible to prevent unauthorized vehicle exits.
(2) The lock plate and the elevating mechanism are coupled by a rigid component. For this reason, when an impact force is applied to the lock plate, the impact force may be directly transmitted to the lifting mechanism.
(3) In order to raise and lower the lock plate by the elevating mechanism, a complicated structure (slide elevating member and inclined plate) is required.
(4) When the compressor does not operate due to a power failure or the like, the lock plate cannot be lowered.

  In view of the above problems, an aspect of the present invention provides a car stop device that can prevent unauthorized shipment with a simple structure, is less likely to be damaged, and can reliably exit a vehicle even in the event of an abnormality such as a power failure. .

  In view of the above problems, the first means is a car stop device installed in a parking lot, and includes a car stop member that moves up and down when the vehicle is loaded and unloaded, and a lift mechanism that lifts and lowers the car stop member. The vehicle bottom detection unit further includes a vehicle bottom detection unit that detects the vehicle bottom when the vehicle rises, and the vehicle bottom detection unit includes: A configuration is adopted in which a limit switch provided between the side base and the lifting mechanism side base is provided. For this reason, since the limit switch is disposed between the top plate side base and the lifting mechanism side base, intrusion of dust and water near the limit switch is prevented.

  In the second means, in addition to the structure of the first means, the limit switch is arranged so that the state is switched when the top plate side base and a part of the elevating mechanism side base are in contact with each other. Adopted. For this reason, the raising of the lifting mechanism side base stops before an excessive force is applied to the limit switch.

  In addition to the configuration of the first unit or the second unit, the third unit further includes a spring member between the vehicle stopper member and the lifting mechanism or between the top plate side base and the lifting mechanism side base. Is adopted. For this reason, when the vehicle stop member is raised by the lifting mechanism and comes into contact with the vehicle bottom, the vehicle stop member stops rising. On the other hand, the lifting mechanism continues to operate until a stop command is received, but the lifting operation is decelerated by the elastic force of the spring member.

  The fourth means employs a structure in which the vehicle stop member and the lifting mechanism are pin-coupled or link-coupled in addition to any of the structures of the first means to the third means. For this reason, even if the vehicle stopper is inclined with respect to the lifting mechanism, the inclination is absorbed by pin coupling or link coupling. Therefore, the inclination is not directly transmitted to the lifting mechanism.

  The fifth means further includes a housing for accommodating the car stopper member in addition to the structure of any one of the first means to the fourth means, and a resin member at least at a position where the car stopper member and the housing face each other. It has a configuration that is provided. The vehicle stopper and the housing face each other with a slight gap. When the car stopper member moves up and down, the car stopper member and the housing move relative to each other. At this time, since the resin member is attached to either or both of the vehicle stopper member and the housing, the vehicle stopper member is prevented from being caught by the housing due to the low friction coefficient of the resin member.

  In the sixth means, in addition to the structure of any one of the first means to the fifth means, at a position where the car stopper member and the housing face each other, at least a part of the end portion of the resin member or the car stopper member The chamfered portion is formed. Thereby, when a housing and a vehicle stop member slide with respect to a resin member, both are caught by the effect | action of a chamfering part.

  In the seventh means, in addition to the configuration of the fifth means or the sixth means, the housing has a housing main body, and the interior of the housing main body is divided into a main chamber for housing the vehicle stopper member and a control unit chamber for housing the control unit. A configuration is adopted in which a partition for separation and a lid member for sealing the control unit chamber and engaging the housing body and the partition are provided. For this reason, even if the vehicle stop member is inclined due to illegal delivery or the like and a large force is applied to the partition wall, the force applied to the partition wall is transmitted to the housing body via the lid member. When the housing main body is installed in the parking lot, the periphery of the housing main body is surrounded by concrete or the ground. For this reason, the force transmitted to the housing body is supported by the concrete or the ground, and the partition wall is prevented from being damaged.

  The eighth means adopts a configuration in which the lifting mechanism is an actuator whose state does not change by an external force in addition to the configuration of any one of the first to seventh means. For this reason, even if a downward external force is applied to the car stopper member due to unauthorized shipping or the like, the elevating mechanism suppresses the descent of the car stopper member. Therefore, illegal shipping can be effectively prevented as compared with the pneumatic lifting mechanism.

  In the ninth means, in addition to the configuration of any one of the first means to the eighth means, the elevating mechanism includes a stroke motor, and the stroke motor can be changed between an upright state and an inclined state. The structure is adopted. For this reason, even when the lifting mechanism stops due to, for example, a power failure, the lifting mechanism can be tilted. When the lifting mechanism is inclined, the distance in the height direction between the lower end portion and the upper end portion of the lifting mechanism is shortened. As a result, the vehicle stopper can be lowered. By lowering the car stop member, the vehicle can be delivered even during a power failure.

  The tenth means adopts a structure in which the amount of inclination of the stroke motor is such that the top board is flush with the road surface in addition to the structure of the ninth means. By doing so, the vehicle stopper can be sufficiently lowered even during a power failure or the like, and the vehicle can be discharged smoothly.

  In the eleventh means, in addition to the ninth means or the tenth means, the stroke motor is provided with a cylinder, a shaft extending and contracting with respect to the cylinder, an upper end and a lower end of a moving range of the shaft. An upper auto switch and a lower auto switch for detecting the above are provided. For this reason, reaching the upper end or lower end of the moving range of the shaft is sent to the control unit, and the stroke motor can be stopped. In addition, the moving range of the shaft can be easily changed simply by changing the positions of the upper auto switch and the lower auto switch.

  In the twelfth means, in addition to the configuration of any one of the first means to the ninth means, a strength reducing portion is formed at the lower end portion of the lifting mechanism, and the strength of the strength reducing portion is the same as that of the lifting mechanism. The structure is lower than the strength of the part. By carrying out like this, when a big force is added to the raising / lowering mechanism from the vehicle stop member due to unauthorized shipping or the like, the main part of the raising / lowering mechanism is not damaged, and the strength reducing portion is damaged. Thereby, an expensive raising / lowering mechanism is protected.

  According to the thirteenth means, in addition to any of the configurations of the ninth means to the twelfth means, the operation unit of the tilt function is outside the parking spaces of the parking lot when the car stopper device is viewed in plan. The composition is taken. For this reason, even if the vehicle completely covers and hides the vehicle stop member, the tilting mechanism can be used by operating the operation unit, and the vehicle stop member can be lowered in the event of a power failure, etc. It is.

  The fourteenth means is, in addition to the configuration of the eighth means, the actuator is a stroke motor, and the elevating mechanism contacts the elevating member connected to the vehicle stop member and elevating in the vertical direction, and the lower part of the elevating member. The stroke motor is connected to the slide member and expands and contracts along the horizontal direction. For this reason, a stroke motor can be installed along a substantially horizontal direction, and what is necessary is just to move a slide member to a horizontal direction in order to raise / lower a raising / lowering member. For this reason, the height of the lifting mechanism itself can be kept low, and the height of the housing can also be kept low. As a result, the depth of the hole when installing the car stopper can be reduced.

  In the fifteenth means, in addition to the structure of the fourteenth means, the inclined surface is formed by an inner wall surface of an inclined elongated hole provided in the slide member, and a lower portion of the elevating member is disposed in the inclined elongated hole. In the vicinity of the slide member, a guide member for guiding the vertical movement of the elevating member is provided. For this reason, when the slide member moves to one side (for example, to the left), the elevating member can be raised by the action of the inclined slot. On the other hand, when the slide member moves to the other side (for example, to the right), the elevating member can be forcibly lowered by the action of the inclined elongated hole.

  In the sixteenth means, in addition to the structure of the fifteenth means, a vertical elongated hole is formed in the guide member along a vertical direction, and a predetermined bearing is provided at a lower portion of the elevating member, and the vertical The bearing is arranged in the long hole. For this reason, when a raising / lowering member raises / lowers, a bearing will move in a vertical elongate hole, and a raising / lowering member can raise / lower smoothly.

  In addition to the structure of the fourteenth means, the seventeenth means includes a substantially L-shaped guide member comprising a first portion extending in the vertical direction and a second portion extending in the substantially horizontal direction in the vicinity of the slide member. The first and second portions are formed with first and second elongated holes, and an elevating member pin is provided at a lower portion of the elevating member, and the elevating member pin moves in the first elongated hole. The slide member is provided with a slide member pin, and the slide member pin is movable in the second elongated hole. For this reason, the elevating member is guided in the vertical direction by the guide member, while the slide member is guided in the horizontal direction.

  In addition to the configuration of the seventeenth means, the eighteenth means adopts a configuration in which the elevating member pin and the slide member pin are connected by a predetermined arm member. For this reason, the arm member also moves with the movement of the slide member. And since an arm member moves a raising / lowering member pin, even when a vehicle stop member is caught, a vehicle stop member can be forced down.

  In the nineteenth means, in addition to the structure of the seventeenth means, the guide member is provided with a pulley, and the elevating member and the slide member are connected by a wire hung on the pulley. Is adopted. For this reason, when the slide member moves in the direction in which the elevating member is lowered, the movement of the slide member generates a force for lowering the elevating member by the wire and the pulley. Thereby, the elevating member can be forcibly lowered.

  In spite of a simple structure, the vehicle stop device of the present invention can decelerate the lifting mechanism with the elastic force of the spring member, and can reduce the transmission of impact force from the vehicle stopping member to the lifting mechanism. In addition, it is possible to easily prevent / eliminate the vehicle stop member from being caught on the housing, and to effectively prevent the vehicle from being illegally issued.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[Overview]
FIG. 1A, FIG. 1B, and FIG. 1C are three views showing the overall outline of the car stopper device 1 according to this embodiment. The vehicle stop device 1 includes a housing 21 that is buried in the ground and accommodates various components, a vehicle stop member 31 that prevents the parked vehicle from being left, and the vehicle stop member 31 is a bottom portion of the vehicle (hereinafter referred to as “vehicle”). A vehicle bottom detection unit 41 that detects contact with the bottom), a lift mechanism 51 that lifts and lowers the vehicle stopper 31, and a control unit 61 that controls the vehicle bottom detection unit 41 and the lift mechanism 51.

[housing]
The housing 21 is configured, for example, by riveting metal plate materials, and includes a substantially rectangular parallelepiped housing main body 211 and a partition wall 213 provided in an intermediate region of the housing main body 211. The strength of the housing main body 211 is ensured by the concrete placed around and the ground strength of the ground. The partition wall 213 is for separating the space in the housing 21 into a main chamber 215 in which the vehicle stopper member 31 is accommodated and a control unit chamber 217 in which the control unit 61 is accommodated. The partition wall 213 is also made of a metal plate material, and is fixed to the housing body 211 by, for example, rivet bonding or welding.

  The bottom surface and side surface of the housing 21 are surrounded by a plate material, whereas the top surface is opened. The opening portion of the main chamber 215 is a portion where the car stopper member 31 enters and exits. When the vehicle stopper member 31 is completely stored, the opening portion of the main chamber 215 is closed by the top plate 311 of the vehicle stopper member 31. The control unit chamber 217 is also open at the top, but is sealed with a predetermined lid member 219 after the control unit 61 is accommodated. One end of the lid member 219 (the left end of the lid member 219 in FIG. 1B) is fitted into the upper end of the partition wall 213, while the other end (the right end) of the lid member 19 is a predetermined end. It is fixed to the stay 221 of the housing body by bolts. For this reason, even if a force that pushes the partition wall 213 rightward from the vehicle stopper member 31 is applied, the force is transmitted to the housing body 221 via the stay 221 by the lid member 219. At this time, the strength of the housing main body 211 is secured by surrounding concrete or the like, so that the partition wall can be firmly supported against the force. The heights of the housing body 211 and the partition wall 213 are set so that the upper end portions thereof are at the same level as the road surface G when embedded in a parking lot.

[Car stop member]
The vehicle stop member 31 includes a metal top plate 311, a first side plate 313, a second side plate 315, and a resin member 317 attached to the outer surface of the second side plate 315. The top plate 311 is a plate having a shape and a size that substantially seals the opening of the main chamber 215 of the housing body 211. When the vehicle is parked, the top plate 311 comes into contact with the bottom of the vehicle as the vehicle stop member 31 rises. On the other hand, when the vehicle is not parked, the level of the road surface G becomes the same level as the car stop member 31 is lowered. For this reason, the top plate 311 has such strength that the vehicle tire does not deform even when it passes over the top plate 311.

  The first side plate 313 is formed by cutting out a single steel plate integrally with the top plate 311 and bending the boundary line between the top plate 311 and the first side plate 313 at a substantially right angle. The second side plate 315 is made of a member having a C-shaped cross section called a so-called C channel. This C-shaped cross section is shown in FIG. 1 (A) which shows a plan view of the car stopper device 1. The second side plate 315 is attached to the lower surface of the top plate 311 and the surface of the first side plate 313 at both ends in the longitudinal direction of the top plate 311 by welding, and extends vertically downward (FIG. 1B). reference). The portion extending vertically downward serves as a leg and faces the surface of the housing body 211 and the partition wall 213. Although the second side plate 315 of the present embodiment is configured by a member different from the top plate 311, the top plate 311 and the second side plate 315 may be integrally formed. In that case, the top plate 311 portion and the second side plate 315 portion are cut out with a single steel plate, bent at a substantially right angle at the boundary line between the top plate 311 and the second side plate 315, and further the second side plate. What is necessary is just to shape | mold 315 in C shape. Furthermore, you may form all the top plate 311, the 1st side plate 313, and the 2nd side plate 315 from one steel plate. The top plate 311 and the side plates 313 and 315 may be made of a material other than metal (for example, hard plastic) as long as sufficient strength can be secured.

  The resin member 317 attached to the outer surface of the second side plate 315 is made of plate-like MC nylon (registered trademark). MC nylon (registered trademark) is excellent in mechanical strength, wear resistance and friction properties. In particular, as for the friction characteristics, MC nylon (registered trademark) has a self-lubricating property, and thus has a low coefficient of friction even without a lubricating oil. For this reason, the resin member 317 plays a role of reducing the frictional force between the housing main body 211 and the partition wall 213 and the second side plate 315 described above. In the present embodiment, the resin member 317 is attached to a portion corresponding to the short side of the top plate 311 of the three side surfaces of the second side plate 315 with a narrow width. However, the resin member 317 may be attached to the entire outer surface of the second side plate 315. The material of the resin member 317 is not limited to MC nylon (registered trademark), and any material having a low friction coefficient can be replaced.

  2A, 2B, and 2C are diagrams for specifically explaining the resin member 317. FIG. Here, FIGS. 2A and 2B are views showing a state in which the resin member 317 is attached to the second side plate 315. FIG. 2B is an enlarged view of a portion surrounded by a dotted circle in FIG. As shown in FIG. 2B, an arc-shaped chamfered portion R is formed at the lower end portion of the resin member 317. This is to prevent the corners of the resin member 317 from being caught on the housing body 211 and the partition wall 213 when the second side plate 315 of the vehicle stopper member slides on the housing body 211 and the partition wall 213. is there. On the other hand, FIG. 2C is a diagram showing another embodiment, in which a resin member 317c is attached to the housing body 211 side. In this case, it is desirable to form an arc-shaped chamfered portion Rc at the lower end portion of the second side plate 315c. This is to prevent the corner portion of the second side plate 315c from being caught on the surface of the resin member 317c. As described above, the resin members 317 and 317c may be attached to either the second side plates 315 and 315c or the housing main body 211 (partition wall 213). In some cases, the resin members 317 and 317c may be attached to both the second side plates 315 and 315c and the housing body 211 (partition wall 213).

[Car bottom detection unit]
The vehicle bottom detection unit 41 is for detecting that the vehicle stop member 31 is raised and the top plate 311 is in contact with the vehicle bottom. Details of the bottom detection unit 41 are shown in FIG. The vehicle bottom detection unit 41 includes a top plate side base 411 attached to the lower surface of the top plate 311, a lifting mechanism side base 413 facing the top plate side base 411, and a limit switch installed on the lifting mechanism side base 413. 415, and a spring member 417 provided between the top plate side base 411 and the lifting mechanism side base 413.

  The top plate side base 411 has a rectangular parallelepiped shape with a low height like a lid of a lunch box, and the lower surface is opened. The top plate side base 411 is attached to the top plate 311 with two screws. However, when the top plate side base 411 is made of metal, it may be attached to the top plate 311 by welding. Further, when the top plate side base 411 is made of resin, it may be attached to the top plate 311 using an adhesive. A stud bolt 419 extends vertically downward from the ceiling surface of the top plate side base 411. The stud bolt 419 is fixed by being screwed into a female screw hole (not shown) formed in the top plate side base 411. However, the stud bolt 419 may be attached to the top plate side base 411 using a technique such as press fitting or welding. The top plate side base 411 is not essential, and the top plate side base 411 can be omitted by fixing a stud bolt to the lower surface of the top plate 311. In that case, in the following description, the “top plate side base” is referred to as “top plate”.

  The elevating mechanism side base 413 has a rectangular parallelepiped shape with a low height like the main body of the lunch box, and the upper surface is opened. That is, the top plate side base 411 is shaped upside down. However, the elevating mechanism side base 413 of this embodiment has a smaller size than the top plate side base 411 so that it can enter the inside of the top plate side base 411. Further, a through hole (not shown) corresponding to the stud bolt 419 described above is formed on the bottom surface of the lifting mechanism side base 413. Then, the elevating mechanism side base 413 is positioned so that the stud bolt 419 passes through the through hole. Thereby, as shown in FIG. 3, the top plate side base 411 and the elevating mechanism side base 413 are combined to form a substantially closed space. For this reason, it can prevent that the limit switch 415 mentioned later is exposed to dust and water.

  A limit switch 415 is disposed on the lifting mechanism side base 413. The limit switch 415 is configured such that the switch arm 415a is pushed down when the top plate side base 411 approaches. When the switch arm 415a is pushed down, the limit switch 415 is turned on, and the information is transmitted to the control unit 61 described later. FIG. 3 shows a state where the top plate side base 411 is sufficiently separated from the limit switch 415. The structure of this limit switch 415 is an example. Any limit switch can be used as long as it can detect the approach of the top plate base 411.

  The above-described stud bolt 419 penetrates the spring member 417 and is disposed between the ceiling of the top plate side base 411 and the bottom surface of the lifting mechanism side base 413. Then, when the nut 421 is screwed into the stud bolt 419 and the lifting mechanism side base 413 approaches the top plate side base 411, the spring member 417 is compressed more than the natural length. That is, the spring member 417 is a compression spring. Thereby, the spring member 417 generates an elastic force. In the present embodiment, the two spring members 417 are set so that an elastic force of about 10 kg is generated. However, the value of the elastic force is only an example, and may be in a state where no elastic force is generated, may be in a state where a slight elastic force is generated, or an elastic force exceeding 10 kg is generated. May be.

  Two nuts 421 are screwed into each stud bolt 419. This is to prevent the nut 421 from loosening by using a double nut. However, if a nut having a loosening prevention mechanism is used, it is not necessary to use a double nut. In the present embodiment, two sets of stud bolts 419 and spring members 417 are provided. However, only one set of the stud bolt 419 and the spring member 417 may be provided, or three or more sets may be provided. Further, if the movement of the spring member 417 can be suppressed, the stud bolt 419 and the spring member 417 may be installed at different positions.

[Elevating mechanism]
Returning to FIG. 1A, the elevating mechanism 51 will be described. The elevating mechanism 51 is for elevating the vehicle stopper member 31 via the above-described vehicle bottom detection unit 41. The elevating mechanism 51 of this embodiment is a stroke motor. The stroke motor includes a motor base 511, a motor 513 fixed to the motor base 511, a cylinder 515 fixed to the motor base 511, and a shaft 517 accommodated in the cylinder 515. The shaft 517 is pin-coupled to the lifting mechanism side base 413 by an upper pin 519. On the other hand, the motor base 511 is pin-coupled to the lifting mechanism base 521 by a lower pin 523. Instead of pin coupling, link coupling may be used. Here, the link connection includes a combination of a pin and a link.

  Inside the motor base 511, a pinion (not shown) attached to a rotating shaft (not shown) of the motor 513 and a gear (not shown) attached to a screw shaft (not shown) in the cylinder 515 are housed. ing. The pinion and the gear are engaged with each other. For this reason, when the motor 513 rotates, the screw shaft rotates in the cylinder 515. The rotational movement of the screw shaft is converted into the vertical movement of the shaft 517. As a result, the shaft 517 expands and contracts with respect to the cylinder 515. The operation of the motor 513 is controlled by the control unit 61. In this embodiment, a stroke motor is used as the lifting mechanism 51, but other actuators such as a hydraulic cylinder may be used.

  As shown in FIG. 1C, the lifting mechanism base 521 has a substantially L-shaped cross section, and is disposed inside a base rail 525 having a C-shaped cross section. The lifting mechanism base 521 is configured to be able to move inside the base rail 525. As described later, this is because the vehicle stopper member 31 is lowered by inclining the elevating mechanism 51 in an emergency. However, the lifting mechanism base 521 may have any structure as long as vertical movement is restricted and horizontal movement is allowed.

  A base movement mechanism is engaged with the lifting mechanism base 521. This pedestal moving mechanism includes a pedestal nut 527 fixed to the lifting mechanism pedestal 521, a long screw 529 screwed into the pedestal nut 527, and a handle 531 attached to the end of the long screw 529. The long screw 529 passes through the partition wall 213, and handle side nuts 533 are attached to both sides of the partition wall 213. These handle side nuts 533 are for restricting the movement of the long screw 529 in the horizontal direction. For this reason, when the long screw 529 is rotated by the handle 531, the pedestal nut 527 is moved in the horizontal direction, and thereby the lifting mechanism pedestal 521 is moved in the horizontal direction (left and right direction in FIG. 1B).

  Since the elevating mechanism 51 is connected to the car stopper member 31 via the spring member 417, it has a function of mitigating the impact force applied to the car stopper member 31 due to unauthorized shipping. However, there is a case where it is not possible to sufficiently cope with an impact force with a large descending amount. In this case, there is a possibility that the elevating mechanism 51 may be damaged if no modification is made. The elevating mechanism 51 of the present embodiment is a stroke motor and is a very expensive part. For this reason, it is desirable to provide a structure that protects the stroke motor by making it easy to break parts other than the stroke motor against impact force.

  FIG. 7A and FIG. 7B are diagrams illustrating a structure for protecting the stroke motor. In this figure, a strength reducing portion 55 is formed at the lower end portion of the stroke motor. The strength reducing portion 55 has a structure in which two plate members 551a and 551b inclined at approximately 45 degrees are fixed by two bolts 553a and 553b. For this reason, the lower end part of the stroke motor is being fixed to the raising-lowering mechanism base 521 at the time of normal. A tension spring 555 extending from the inner wall of the housing body 211 is attached above the strength reducing portion 55 and below the motor base 511.

  An upper auto switch 535a is provided at the upper part of the cylinder 515, while a lower auto switch 535b is provided at the lower part of the cylinder 515. The upper and lower auto switches 535a and 535b are for setting the upper end and the lower end of the moving range of the shaft 517. A specific structure is a sensor that detects a change in a magnetic field. A magnet is attached to the shaft 517, and when the magnet moves close to the upper auto switch 535a and the lower auto switch 535b as the shaft 517 moves up and down, it is detected that the shaft 517 has reached the upper end or the lower end. be able to. When the upper end or the lower end is detected, the signal is transmitted to the control unit 61, and a stop signal is transmitted from the control unit 61 to the motor 513.

  In particular, the upper auto switch 535a is important. This is because, for example, in the case of a vehicle having a high vehicle height such as a four-wheel drive vehicle, the height to the vehicle bottom is also high. For this reason, depending on the stroke of the elevating mechanism 51, the car stopper member 31 may not be raised to the vehicle bottom. If the vehicle stop member 31 does not contact the vehicle bottom, the limit switch 415 of the vehicle bottom detection unit 41 is not turned on, and the lifting mechanism 51 cannot be stopped. In order to avoid such a problem, the upper auto switch 535a functions. Moreover, there is a case where it is desired to change the highest rising position of the car stop member 31 for each parking lot. This is to prevent troubles such as generation of scratches when the vehicle stopper 31 comes into contact with the vehicle bottom. In the case of a conventional car stop device, in order to change the highest lift position of the car stop member, a complicated structure and additional parts are required. For example, in the case of a flap-type car stop device, an additional mechanism for regulating the movable range of the flap is required. In the case of a pneumatic car stopper, it is necessary to change the air valve. On the other hand, if it is the car stop apparatus 1 of this embodiment, a maximum raise position can be easily changed only by changing the position of the upper auto switch 535a. The same applies to the lower auto switch 535b.

[Operation of each part]
[Car bottom detection unit]
4 (A) and 4 (B) are diagrams illustrating the principle that the vehicle bottom detection unit 41 detects the vehicle bottom B. FIG. Here, FIG. 4A shows a state where the vehicle bottom B is not detected, and FIG. 4B shows a state where the vehicle bottom B is detected. First, as shown in FIG. 4A, when the top plate 311 is not in contact with the vehicle bottom B, the elevating mechanism side base 413 is at the lowest position regulated by the nut 421. Accordingly, the switch arm 415a of the limit switch 415 is not in contact with the top plate side base 411, and the limit switch 415 remains off.

  On the other hand, when the vehicle is parked in the parking lot, the vehicle stopper 31 is raised by an input signal of a vehicle detection sensor (not shown). The raising of the vehicle stopper 31 is performed by the control unit 61 rotating the motor 513 of the lifting mechanism 51. As shown in FIG. 4B, when the top plate 311 comes into contact with the bottom of the vehicle as the shaft 517 of the elevating mechanism 51 rises, the top plate 311 is prevented from rising. However, the shaft 517 continues to rise against the elastic force of the spring member 417. For this reason, the spring member 417 is further compressed while the elevating mechanism side base 413 is raised. For this reason, the elevating mechanism is decelerated as the elastic force increases. Then, the switch arm 415a of the limit switch 415 comes into contact with the ceiling of the top plate side base 411, and the limit switch 415 is turned on. At this time, as shown in FIG. 4B, the upper end of the side wall of the lifting mechanism side base 413 is in contact with the ceiling portion of the top plate side base 411. For this reason, the elevating mechanism side base 413 does not approach the top plate side base 411 any more, and an excessive force is not applied to the limit switch. Even in this case, the contraction amount is set so that the spring member 417 is not completely compressed. When the limit switch 415 is turned on, the information is sent to the control unit 61. The control unit 61 generates a signal for stopping the motor 513 and transmits it to the motor 513. Thereby, the raising / lowering mechanism 51 stops.

  As described above, by providing the spring member 417 between the top plate 311 and the lifting mechanism 51 (more specifically, the top plate side base 411 and the lifting mechanism side base 413), the following technical effects can be obtained. Play. That is, the engagement of the vehicle stopper member 31 with the housing 21 can be easily eliminated, and transmission of an excessive impact force to the elevating mechanism 51 can be reduced.

  First, the former is achieved by the following principle. First, the vehicle stop member 31 is bitten by the housing body 211 and the partition wall 213 when the vehicle is illegally shipped. When the vehicle is illegally left in a state where the car stopper member 31 is raised, a large external force in the horizontal direction or the vertical direction is applied to the car stopper member 31 from the tire. In particular, as shown in FIG. 5, when the tire T rides on a position deviated from the longitudinal center of the car stopper member 31, the car stopper member 31 is inclined. However, only a slight gap is provided between the vehicle stopper member 31 and the surface of the housing 21. For this reason, as shown in FIG. 5, the car stopper member 31 is bitten by the housing main body 211 and the partition wall 213 due to the inclination of the car stopper member 31.

  In the case of a conventional car stop device, the relative movement between the car stop member and the elevating mechanism is strictly regulated. For this reason, the vehicle stopper member cannot be moved with respect to the housing. However, in the car stopper device of the present embodiment, the car stopper member 31 and the lifting mechanism 51 are allowed to move relative to each other by the spring member 417. For this reason, the vehicle stopper 31 can be moved separately from the lifting mechanism 51. Due to such structural features, biting into the housing main body 211 and the partition wall 213 can be easily eliminated by slightly moving the car stopper member 31. Further, the inclination of the car stopper member is absorbed by the spring member 417, the gap between the car stopper member 31, the housing body 211, and the partition wall 213, the elastic deformation of the resin member, and the upper pin 519. For this reason, the inclination of the vehicle stop member 31 is not directly transmitted to the lifting mechanism 41. Furthermore, the top plate or the like of the car stopper member may be made of an elastically deformable material so that the force is absorbed thereby to reduce the load on the lifting mechanism at the time of illegal shipment.

  Next, the latter effect is realized by the following principle. That is, a large external force is applied to the car stop member 31 due to unauthorized shipping. This is the same as described in the former effect. At this time, in the structure in which the vehicle stopper member 31 and the lifting mechanism 51 are rigidly connected, the impact force applied to the vehicle stopper member 31 is directly transmitted to the lifting mechanism 51. For this reason, the raising / lowering mechanism 51 will be damaged by the big impact force. On the other hand, in the case of the car stopper device 1 according to the present embodiment, the spring member 417 alleviates the transmission of an impact force to the elevating mechanism 51, so that the elevating mechanism 51 can be prevented from being damaged.

[Inclination function of lifting mechanism]
Next, the tilt function of the elevating mechanism 51 will be described with reference to FIG. The tilt function 51 is a function that assumes a case where the vehicle stop member 31 does not descend due to a power failure or the like. As described above, the lifting mechanism base 521 can be moved in the horizontal direction by the base moving mechanism. That is, when the handle 531 is rotated, the long screw 529 is rotated, and the lifting mechanism base 521 can be moved in the horizontal direction (rightward in FIG. 6). At this time, the lifting mechanism 51 is pin-coupled to the vehicle bottom detection unit 41 and at the same time is also pin-coupled to the lifting mechanism base 521. For this reason, the raising / lowering mechanism 51 can incline with the movement of the raising / lowering mechanism base 521.

  On the other hand, the movement of the vehicle stopper member 31 in the horizontal direction is restricted by the housing body 211 and the partition wall 213. At this time, since the elevating mechanism 51 is stopped, the relative distance between the upper pin 519 and the lower pin 523 is unchanged from before the power failure. For this reason, the car stopper member 31 is lowered as the elevating mechanism 51 is inclined. In FIG. 6, the vehicle stopper 31 protrudes somewhat from the upper end of the housing main body 211, but it is easy to leave the vehicle with this amount of protrusion. However, the top plate 311 can be flush with the road surface G by increasing the distance from the lifting mechanism 51 to the partition wall 213. In addition, the said inclination function can be utilized not only at the time of a power failure but in the case of failure of the vehicle stop apparatus 1.

  Next, based on FIG. 7 (A) and FIG. 7 (B), the effect | action of the protection structure of the raising / lowering mechanism 51 is demonstrated. FIG. 7A shows the lifting mechanism (stroke motor) in a normal state. In this state, if an illegal shipment is performed, a large force is applied to the stroke motor in the vertically downward direction. For this reason, in the case of a normal stroke motor, main components are damaged. However, in this embodiment, the strength reduction part 55 is formed in the lower end part of the stroke motor. The strength reducing portion 55 includes two inclined plate members 551a and 551b and bolts 553a and 553b for fixing them. For this reason, when a vertically downward force exceeding an allowable value is applied to the stroke motor, a shearing force is generated along the inclined contact surfaces of the two plate members. The bolts 553a and 553b are broken by this shearing force, and the two plate members 551a and 551b are separated. At this time, since the tension spring 555 is provided above the strength reducing portion 55, the lower end portion of the stroke motor is pulled leftward so that the force from above can be released.

  FIGS. 8A and 8B are views showing a state in which the vehicle stopper member 31 of the present embodiment is completely accommodated in the housing 21, and is a state before the vehicle enters or after the vehicle exits. At this time, the top plate 311 is lowered to the same level as the road surface G. Moreover, as shown in FIG. 8 (B), when the car stop device 1 is installed in a parking lot, it is installed at a substantially intermediate portion in the longitudinal direction of the parking space. This is a position corresponding to between the front wheel and the rear wheel, and when the vehicle stop member 31 is raised, it comes into contact with the vehicle bottom between the front wheel and the rear wheel.

  In addition, according to the present embodiment, the overall length of the vehicle stopper can be shortened as compared with the conventional vehicle stopper. This is because, in the case of a conventional car stop device, if the car stop member does not descend due to a power failure or being caught on the vehicle, it is necessary to push the car stop member down with hands or feet. At this time, the vehicle stopper member needs to be exposed outside the parking space. This is because the car stopper member cannot be pushed down when the car stopper member is completely hidden under the vehicle. On the other hand, in the case of the car stop device 1 according to the present embodiment, even if the car stop member 31 is completely hidden under the vehicle in the parking space, the cover member 219 is not hidden unless the cover member 219 of the control unit chamber 215 is hidden. This is because the vehicle stopper member 31 can be lowered by operating the handle 531 by removing the wheel. Thereby, the vehicle stop member 1 can be made compact and cost can also be reduced. Further, in the case of the conventional car stopper, after the car stopper member is pushed down, it is necessary to lock the car stopper member so that it does not rise again (two operations are required). On the other hand, in the case of the car stopper device 1 of the present embodiment, only the operation of the handle 531 is performed (one operation), and the operation can be performed without putting a hand under the vehicle, so that the maintainability and the operation efficiency are improved. In other words, in the car stopper device 1 of this embodiment, it is not necessary to extend the car stopper member to the outside of the parking space.

[Second Embodiment]
Next, the lifting mechanism 91 according to the second embodiment will be described with reference to FIGS. 9 and 10. The present embodiment is different from the first embodiment in the structure of the lifting mechanism 91 . The lifting mechanism 91 is characterized in that the slide member 915 has an inclined elongated hole 915a. A part of the inner wall surface of the inclined elongated hole 915a is an inclined surface. A roller 917 is provided below the elevating member 913 corresponding to the inclined long hole 915a. Therefore, the roller 917 is inserted into the inclined long hole 915a, and moves in the inclined long hole 915a as the slide member 915 moves in the horizontal direction. For this reason, when the slide member 915 moves to the left, the roller 917 rises. Conversely, when the slide member 915 moves to the right, the roller 917 descends. As the roller 917 moves up and down, the elevating member 913 moves up and down. Details will be described below.

  The slide member 915 of the present embodiment includes a substantially triangular main portion 915b and first and second extending portions 915c and 915d extending in the horizontal direction and in the opposite directions from the lower portion of the main portion 915b. . The end of the stroke motor 920 is connected to the second extending portion 915d. A plate-shaped holding plate 921 is provided above the first and second extending portions 915c and 915d. For this reason, even if the slide member 915 tries to move in the vertical direction, the holding plate 921 suppresses the movement in the vertical direction. Note that the notch is formed in the holding plate 921 only in the moving range of the slide member 915. Therefore, the slide member 915 can move in the horizontal direction.

  As shown in FIG. 9A, guide members 911 are provided on both sides of the slide member 915 along the vertical direction. The guide member 911 guides the vertical movement of the elevating member 913. The guide member 911 is formed with a vertical slot 911a. The elongated hole 911a is formed from the vicinity of the upper end of the guide member 911 to the vicinity of the lower end.

  FIG. 10 is a cross-sectional view showing the lower part of the elevating member 913, and is a cross-sectional view taken along the line XIV-XIV in FIG. As shown in FIG. 10, a collar 913b is fitted on a predetermined bolt shaft 913a, and a roller 917 is mounted on the outer periphery of the collar 913b. On both sides of the roller 917, elevating member legs 913d are provided so as to sandwich the roller 917 with a predetermined washer. Further, a bearing 913e is provided on the outside of the elevating member leg portion 913d via a washer. The bearing 913e is disposed in the above-described elongated hole 911a in the vertical direction, and can move in the elongated direction in the elongated hole 911a. In this figure, the roller 917 is sandwiched between the inclined surfaces of the slide member 915 from the vertical direction.

[Action]
Next, the operation of the second embodiment will be described with reference to FIG. FIG. 9 (B-1) is a diagram illustrating a state where the vehicle stopper member 31 is lowered. Further, the state where the slide member 915 is located on the rightmost side is shown. In such a state, the roller 917 is located at the lowest end of the inclined elongated hole 915a. For this reason, the raising / lowering member 913 is also located in the lowest end part. From this state, the stroke motor 920 starts to extend. Then, the slide member 915 moves to the left. At this time, the bearing 913e is not moved in the horizontal direction because the bearing 913e is disposed in the elongated hole 911a in the vertical direction below the elevating member 913. On the other hand, when the inclined long hole 915a moves rightward in the horizontal direction, the roller 917 starts to climb the inclined surface of the inclined long hole 915a. The climbing operation along the inclined surface causes the roller 917 to move vertically upward.

  As the roller 917 moves vertically upward, the entire lifting member 913 moves vertically upward. When the slide member 915 moves to the left most, the roller 917 and the bearing of the elevating member 913 are positioned at the uppermost part. Accordingly, the vehicle stopper is at the highest position.

  Next, a process for lowering the elevating member 913 will be described. In principle, this is the reverse of the case where the elevating member 913 is raised. However, there may be a case where the vehicle stopper 31 is caught by the housing 21 and cannot be lowered by its own weight. Even in this case, according to the present embodiment, the vehicle stopper member 31 can be forcibly lowered. That is, the slide member 915 moves to the right from the state shown in FIG. Then, the inclined long hole 915a formed in the slide member 915 also moves to the right. Since the inclined long hole 915a is inclined in the downward-left direction, the roller 917 receives a downward force from the inner wall surface on the upper side of the inclined long hole 915a. At this time, the slide member 915 is prevented from being lifted by the above-described holding plate 921. For this reason, the movement to the right in the horizontal direction is continued. When the slide member 915 finally moves to the rightmost side, the elevating member 913 is lowered to the lowermost position (FIG. 9 (B-1)).

[Third Embodiment]
Next, a third embodiment will be described based on FIGS. 11 to 13. The elevating mechanism 71 is arranged between the two L-shaped guide members 711, the elevating member 713 arranged between the two guide members 711 and elevating in the vertical direction, and arranged between the guide members 711 and moving in the horizontal direction. And a slide member 715 to be operated. The elevating mechanism 71 includes an arm member 717 that connects the elevating member 713 and the slide member 715.

[Guide member]
As shown in FIG. 11, in the guide member 711, one L-shaped first portion 711a extends in the vertical direction, and the other second portion 711b extends in the horizontal direction. Further, predetermined elongated holes 711c and 711d are formed in the first and second portions 711a and 711b of the guide member 711 along the respective length directions. Connection members 719a and 719b are provided between the two guide members 711a and 711b at the upper end of the guide member 711. The connecting members 719a and 719b are for connecting the upper ends of the two guide members 711. Further, the connecting members 719a and 719b surround the elevating member 713 together with the guide member 711, and also have a role of preventing the elevating member 713 from shaking. In the present embodiment, two connecting members 719a and 719b having different lengths are provided in order to prevent contact with an inclined surface 715a of a slide member 715 described later. However, the two connecting members 719a and 719b may have the same length as long as they do not contact the slide member 715.

[Elevating member]
The elevating member 713 is composed of a narrow plate-like member. A pin hole 713 a for connecting to the car stopper member 31 is formed at the upper end of the elevating member 713. On the other hand, the lower end portion of the elevating member 713 is an inclined portion 713b. The inclination angle of the inclined portion 713b is not particularly limited, but is about 45 ° as an example in the present embodiment. Further, an elevating member pin 713 c is provided near the lower end portion of the elevating member 713. The elevating member pin 713c is inserted into the elongated hole 711c of the guide member 711 to guide the elevating member 713 so as to move in the vertical direction. For this reason, the lifting member 713 can be lifted and lowered while facing the vertical direction by the action of the connecting members 719a and 719b of the guide member 711 and the lifting member pin 713c.

[Sliding member]
The slide member 715 includes a substantially triangular main portion 715 b that contacts the elevating member 713 and an extending portion 715 c that extends from the main portion 715 b and is connected to the stroke motor 720. The inclined surface 715a of the main portion 715b that contacts the elevating member 713 has substantially the same inclination angle as the inclination angle of the inclined portion 713b of the elevating member 713. For this reason, when the elevating member 713 and the slide member 715 come into contact with each other, the two come into surface contact with the inclined portion 713c of the elevating member 713 and the inclined surface 715a of the slide member 715. However, surface contact is not essential in the present invention. If the elevating member 713 is in contact with the inclined surface 715a of the slide member 715, the elevating member 713 can be moved up and down.

  Further, a slide member pin 715d is provided in a region between the main portion 715b of the slide member 715 and the extending portion 715c. The slide member pin 715d is inserted into the elongated hole 711d of the second portion 711b of the guide member 711. For this reason, when the slide member 715 moves in the horizontal direction, the slide member pin 715d is guided by the elongated hole 711d. A predetermined engagement hole 715e is formed at the end of the extending portion 715c of the slide member 715. The stroke motor 720 is engaged with the engagement hole 715e.

[Arm member]
The arm member 717 is made of a plate-like member and is provided so as to connect the elevating member pin 713c and the slide member pin 715d. A predetermined arm member long hole 717a is formed in a portion of the both ends of the arm member 717 connected to the lifting member pin 713c. For this reason, the elevating member pin 713c can relatively move in the arm member long hole 717a. On the other hand, a circular hole having a size to fit the slide member pin 715d is formed at the end of the arm member 717 and connected to the slide member pin 715d. For this reason, the arm member 717 can rotate around the slide member pin 715d, but the relative movement is restricted. Two arm members 717 are provided so as to sandwich the guide member 711, but only one arm member 717 may be provided.

[Stroke motor]
As shown in FIG. 12A, the elevating mechanism 71 and the vehicle stopper member 31 are accommodated in the housing 21. Unlike the first embodiment, the stroke motor 720 is installed along the horizontal direction. The tip of the stroke motor 720 is engaged with the circular hole 715e of the slide member 715. Since the stroke motor 719 can be installed along the horizontal direction, the height of the housing 21 can be reduced. As a result, when installing the car stop device 51B, the depth of the embedding hole for embedding the housing 21 can be reduced.

  FIG. 12B is a diagram showing the stroke motor 720 in an emergency. As shown in this figure, even when the stroke motor 720 is extended to the maximum length, it is possible to retract the slide member 715 and lower the vehicle stopper 31. Details will be described below.

  A stroke motor pin 719 a is provided at the rear end of the stroke motor 720. In the normal state, the stroke motor pin 719a is housed in a notch 719b formed in the fixed frame. Further, a fastener 719c is connected to the stroke motor pin 719a. One end of the fastener 719 c is connected to the stroke motor pin 719 a, and the other end of the fastener 719 c is fixed to the inner wall of the housing 21. For this reason, even when a force is applied to the stroke motor 720, the stroke motor pin 719a does not come off the notch 719b.

  On the other hand, it is also conceivable that the stroke motor 720 does not shrink due to a failure or the like. In this case, the vehicle stop member 31 does not descend, and the vehicle cannot be released. In order to avoid this, the other end of the fastener 719 c is removed from the housing 21. Then, the stroke motor pin 719a is removed from the notch 719b. As a result, the rear end of the stroke motor 720 can move backward (move to the right in the figure). If the stroke motor 720 moves backward, the slide member 715 can also move backward along with this, and the lifting member 31 can be lowered.

[Action]
Next, based on FIG. 13, the operation of the elevating mechanism 71 according to the third embodiment will be described. 13A shows a case where the elevating member 713 is at the uppermost part, and FIG. 13D shows a case where the elevating member 713 is at the lowermost part. As shown in FIG. 13A, when the elevating member 713 is at the uppermost position, the stroke motor 720 is in the longest state, and the slide member 715 is at the leftmost position. For this reason, the elevating member 713 is in contact with the upper end portion of the inclined surface 715 a of the slide member 715.

  FIG. 13B shows a state where the stroke motor 720 is slightly contracted and the slide member 715 is moved to the right. However, the elevating member 713 is not lowered. For this reason, the elevating member 713 and the slide member 715 are separated from each other. This is not a normal operation but a case where the vehicle stopper 31 cannot be lowered for some reason. For example, it is assumed that the vehicle stopper member 31 is inclined with respect to the housing 21 and cannot be lowered by its own weight. However, when the slide member 715 further moves to the right, the arm member 717 also moves to the right. At this time, the elevating member pin 713c is pulled by the arm member 717. As a result, a vertically downward force is applied to the elevating member 713, and the elevating member 713 can be lowered.

  FIG. 13C shows a state in which the elevating member 713 is lowered and is in contact with the inclined surface 715 a of the slide member 715. Further, when the slide member 715 moves to the right end position, the elevating member 713 comes into contact with the lowermost end portion of the inclined surface 715a of the slide member 715. For this reason, the raising / lowering member 713 descends to the lowest part. It should be noted that the contact between the elevating member 713 and the slide member 715 is maintained if the car stopper member 31 is not caught while the elevating member 713 is lowered from the uppermost part to the lowermost part. This is because the elevating member pin 713c can be lowered by the arm member long hole 717a.

  The above is an explanation when the elevating member 713 descends from the top to the bottom. On the other hand, when the elevating member 713 is raised, the process is reversed. That is, the stroke motor 720 extends to move the slide member 715 to the left. As a result, the elevating member 713 rises while maintaining contact with the slide member 715. When the slide member 715 reaches the leftmost position, the elevating member 713 rises to the top.

[Fourth Embodiment]
Next, a fourth embodiment will be described based on FIG. The fourth embodiment has the same basic components as the third embodiment. On the other hand, this embodiment is different from the third embodiment in that a pulley 817 and a wire 819 are provided. That is, the pulley 817 is rotatably provided on the guide member 811. A wire 819 is wound around the pulley 817, one end of the wire 819 is fixed near the upper end of the elevating member 813, and the other end of the wire 819 is fixed to the rear end of the extending portion 815c of the slide member 815. Yes. By adopting such a configuration, when the slide member 815 moves to the right, the wire 819 pulls the elevating member 813 downward via the pulley 817. The lifting member 813 can be lowered by the force of the wire 819. According to this embodiment, the elevating member 813 can be lowered regardless of the position of the elevating member 813 in the height direction. In this respect, the lifting member 813 can be lowered more reliably as compared to the case where the arm member 717 is used as in the second embodiment. The pulley 817 is supported by a long hole formed in the guide member 811, and thus can move somewhat with respect to the guide member 811.
