Description

  The present invention relates to a parking lock device used in a parking system that controls parking management by locking or unlocking a wheel of a two-wheeled vehicle, in particular, a bicycle in an unmanned management state.

  In recent years, large bicycle parking facilities are often installed near railway stations, but a large number of bicycles cannot be accommodated, and there is a situation where bicycle parking facilities cannot be provided to all those who wish to use the bicycle.

  Therefore, a configuration in which a large number of bicycle parking lock devices are connected along the street without requiring a special location and used appropriately by the user is also widespread. Is basically in an unmanned state of management, and is generally in a state of management in which a management staff sometimes makes a patrol by cracking down on illegal bicycle parking.

  Conventionally, in a parking lock device that is installed based on such unmanned management, a bicycle to be parked is pushed into the rack with respect to the parking lock device, and the lock device is locked when it is pushed all the way into the rack. The form was adopted. However, in such a bicycle parking device in which the bicycle is pushed into the lock device, a so-called stop parking bicycle, in which the user does not push the bicycle all the way in, but is left stationary in the middle of the rack, is suitable. There was no end to unauthorized users leaving without paying.

  Therefore, in recent years, a configuration has been adopted in which a lock arm is advanced from the lower side of a rack and a bicycle tire is held by simply placing the bicycle on the rack without having to be pushed into the rack.

  For example, in Patent Document 1, a protective frame formed in a reverse portal shape with a vertically long cross section is formed at the approximate center of the central longitudinal direction of an outer frame formed in a horseshoe shape with an opening at the top, and a bicycle wheel is mounted. A guide frame that is pivotally supported so that one end is rotated by a load of the load, and a portion of the wheel is held in the vertical direction by the load generated by the rotation of the guide frame in the substantially central width direction of the guide frame. A bicycle parking device is disclosed in which a bicycle is locked by a pair of movable arms that are pivotably opened and closed.

  Patent Document 2 discloses a parking device in which a locking member advances and retreats from only one side of a wheel mount. Further, Patent Document 3 includes a guide wheel at the tip of a holding claw portion of a movable arm. A locking device is disclosed.

  These bicycle parking devices are installed on streets where users who use bicycle parking devices and ordinary pedestrians come and go, so there is no general use of bicycle parking devices in the immediate vicinity of bicycle parking devices. Passersby can come and go without any restrictions. At that time, not only adults but also children and infants cannot be strictly regulated so as not to enter the vicinity of the bicycle parking device. Under such circumstances, the bicycle parking device may be mischievous by an infant or may enter the vicinity of the device, but in such a case, no conventional bicycle parking device has taken any safety measures. It was.

  For example, in the bicycle parking apparatus disclosed in Patent Document 1, when a guide frame is accidentally stepped on by a passerby or the like, particularly an infant, a leg is caught between a pair of movable arms and the risk of injury is denied. Can not.

  Further, even the locking device of Patent Document 2 can easily step on the lower pressing portion of the locking member, and there is a risk of injury to the leg due to the locking member penetrating over the entire width of both guide rods.

  In Patent Document 3, a guide wheel that protects a bicycle tire and rim from damage is attached to the tip of the holding claw of the movable arm. There is a possibility of injury.

  As described above, the conventional parking lock device has a problem in that it is difficult to eliminate the danger of entering an infant when it is installed in large numbers on a roadside in a downtown area in an unmanned state.

  In view of the circumstances as described above, an object of the present invention is to provide a parking lock device that can eliminate as much danger as possible when a passerby other than a bicycle, particularly an infant, accidentally steps on a wheel guide portion or the like. There is.

In order to achieve the above object, a parking lock device according to one aspect of the present invention includes a guide frame, a wheel guide mechanism, and an arm movable mechanism.
The guide frame body includes a first end portion into which a wheel of a two-wheeled vehicle can enter, a second end portion facing the first end portion in the first axial direction, and orthogonal to the first axial direction. A pair of guide plates that oppose each other at a first interval in the second axial direction and guide the movement of the wheel from the first end portion to the second end portion.
The wheel guide mechanism includes a wheel guide disposed inside the guide frame and on which a wheel is placed, and a guide support shaft that supports the wheel guide so as to be tiltable about an axis parallel to the second axis. And having the weight received from the wheel, the wheel guide can be tilted around the guide support shaft from the non-parking position to the parking position.
The arm movable mechanism includes a pair of lock arms disposed on the pair of guide plates, and a pair of arm support shafts that rotatably support the pair of lock arms around an axis parallel to the first axial direction. And have. The pair of lock arms includes a pair of pressed parts that support the wheel guide and rotate the pair of lock arms around the pair of arm spindles when the wheel guide is tilted, and a pair of the lock arms. And a pair of flanges protruding inward from the outside of the pair of guide plates by rotation. The pair of eaves portions are disposed apart from each other with a second interval in the first axial direction.

  The second interval may have a size equal to or greater than the first interval.

  The first interval may be not less than 55 mm and not more than 65 mm.

  Each of the pair of lock arms may be configured by a metal plate, and each of the pair of flange portions is configured by a folded portion in which the metal plate is folded back in the first axial direction. Also good.

  The pair of lock arms may each include a through-hole portion through which the pair of arm support shafts penetrates, and the through-hole portion is the first axial direction of the pair of flange portions with respect to the guide frame body. It may have a shape that allows relative movement.

  The guide frame body may further include a pair of recesses or notches provided on the pair of guide plates and facing the pair of flanges and the second axial direction.

<First Embodiment>
FIG. 1 is an external view of a bicycle parking system according to an embodiment of the present invention. Hereinafter, the whole structure of the bicycle parking system 100 of this embodiment is demonstrated.

[Overall configuration of bicycle parking system]
The bicycle parking system 100 includes a bicycle parking area PA installed between the sidewalk Sw and the roadway St in the street, a number of parking lock devices 1 installed in the bicycle parking area PA, and one end of the bicycle parking area PA. And a settlement machine 6 installed in the machine.

  The bicycle parking area PA is installed on the sidewalk Sw. The sidewalk Sw is slightly higher than the roadway St, and the bicycle parking area PA is often installed on the side of the roadway St of the higher sidewalk Sw. A guardrail (not shown) or the like is installed between the roadway St and the sidewalk Sw. However, the parking area PA and the sidewalk Sw are not particularly provided with a barrier or the like that prevents traffic. However, in order to distinguish the bicycle parking area PA and the driving lane from the sidewalk Sw, the ground of the bicycle parking area PA is painted differently from the ground of the sidewalk Sw, or a bicycle mark (not shown) is drawn. Often to do.

  In the bicycle parking area PA, a base PB that is raised slightly higher than the ground is installed in a long shape along the street. The base PB has a portal shape and is formed of a metal frame having a hollow inside. The base PB is divided into a predetermined length (for example, six parking lock devices) in advance and connected in the longitudinal direction on the street where the base PB is installed. Apparatus 1 is installed. Furthermore, an electric wiring (not shown) is installed inside the base PB, and the settlement machine 6 and each parking lock device 1 are electrically connected. Wiring, piping and the like are not exposed outside the base PB, and consideration is given so that pedestrians and users of the bicycle parking system 100 do not go to the wiring or the like.

  A number of parking lock devices 1 are arranged in parallel on the upper surface of the base PB. The multiple parking lock devices 1 include multiple high-level parking lock devices 1H and multiple low-position parking lock devices 1L, and the handles of the bicycles Bc parked on the adjacent parking lock devices 1 are connected to each other. Both types of parking lock devices 1 (1H, 1L) are alternately arranged along the street so that they do not contact each other. In the example of FIG. 1, the parking lock device 1 on the most adjustment machine 6 side is a high parking lock device 1H, and the left side is the low parking lock device 1L. The bicycle parking lock device 1H and the lower parking lock device 1L are alternately arranged, but only two parking lock devices 1H and 1L are shown for simplicity.

  The user parks the bicycle Bc from the sidewalk Sw side by inserting the wheel W (in most cases, the front wheel) into the parking lock device 1, but in the following description, the insertion direction of the bicycle Bc is the front-rear direction. The description will be made by defining the upper, lower, left and right directions as viewed in the direction. In addition, the parking lock device 1H at the high position and the parking lock device 1L at the low position are collectively referred to as a parking lock device 1 unless otherwise described.

  The checkout machine 6 is configured to control a large number of parking lock devices 1 at a time, and performs a checkout process for a large number of parking lock devices 1. In addition, the control of another block across the street traffic light etc. is performed by arranging another checkout machine, and one checkout machine has many parking lock devices along the street of one block (city block). Configured to control.

  Each parking lock device 1 is assigned a unique serial number and is displayed on the exterior of the parking lock device 1 so as to be visible. In the example of FIG. 1, numbers “1”, “2”,... Are assigned from the parking lock device 1 on the side closest to the checkout machine 6. The user is required to settle the fee after inputting the serial number to the settlement machine 6 in order to change the parking lock device 1 that parked the bicycle Bc from the locked state to the unlocked state.

  The settlement machine 6 is arranged such that the display screen device 601 and the charge accommodation operation unit (operation key group) 602 face the sidewalk Sw. Further, as described above, from the lower part of the checkout machine 6, a large number of electric wirings are wired to each parking lock device 1 through the inside of the base PB. The configuration and operation of the settlement machine 6 will be described later.

  In addition, the installation location of the bicycle parking system 100 is not limited to a street, and may be installed inside a bicycle parking lot where an administrator resides.

[Parking lock device]
Next, the configuration of the parking lock device 1 will be described.

(Basic configuration)
2A and 2B are partially transparent side views showing the internal structure when the parking lock device 1 is viewed from the left side, and are a high position parking lock device 1H (FIG. 2A) and a low position parking lock device. The cross section in the center of the left-right direction of the guide frame 10 in each of 1L (FIG. 2B) is shown.

  The parking lock device 1 includes a guide frame body 10, a wheel guide mechanism 20, an arm movable mechanism 30, and a lock mechanism 40. The guide frame body 10, the wheel guide mechanism 20, the arm movable mechanism 30, and the lock mechanism 40 constitute a main body portion 50 of the parking lock device 1.

  In the parking lock apparatus 1H at the high position shown in FIG. 2A, the main body 50 is installed on the base PB at a position separated from the base PB by the front and rear columns C1, C2. Between the rear end part 11 of the guide frame body 10 and the ground of the parking area PA, a channel-shaped slope F having a U-shaped cross section with an open upper side is attached. Although not shown, the pillars C1 and C2 are square pillars having a hollow interior as a whole, and electric wiring is passed through the inside of the base PB through the inside of the front pillar C1.

  In the parking lock device 1L at the low position in FIG. 2B, the main body 50 including the guide frame 10 is attached to the upper surface of the base PB.

  As described above, in the high-position parking lock device 1H and the low-position parking lock device 1L, the main body 50 itself has the same configuration, and the operation when the bicycle is parked also follows the slope F. The only difference is whether W is lifted and inserted into the guide frame 10 or directly into the guide frame 10. Therefore, in the following description, in the description regarding the configuration and operation of the parking lock device 1, only the relative relationship between the main body 50 of the parking lock device 1 and the bicycle wheel W is assumed.

  Then, the detail of a structure of the main-body part 50 of the parking lock apparatus 1 is demonstrated.

  3A to 3C are a top view, a left sectional view, and a rear view of the main body 50 of the bicycle parking lock device 1, respectively. 4A and 4B are partially transparent perspective views showing the internal structure of the main body portion of the parking lock device 1, wherein A shows a non-parking state (a state before wheel mounting or a wheel detached state), and B is The bicycle parking state (wheel mounting state or wheel housing state) is shown. 4A and 4B, the left and right guide plates are seen through in order to facilitate understanding of the internal state.

(Guide frame)
The guide frame body 10 includes a rear end portion 11 (first end portion), a front end portion 12 (second end portion), and a pair of guide plates 13L and 13R.

  The rear end portion 11 has an entrance 11h through which a wheel W of a bicycle Bc (two-wheeled vehicle) can enter. The front end portion 12 faces the rear end portion 11 in the front-rear direction (first axial direction), and is configured as a closed end portion in the present embodiment. The pair of guide plates 13L and 13R oppose each other with a distance D1 (first distance) in the left-right direction (second axial direction), and move the wheel W that has entered the rear end portion 11 from both the left and right sides in the traveling direction. While supporting, it is possible to guide the movement of the wheel W from the rear end portion 11 to the front end portion 12.

  The guide frame 10 is typically made of a metal material, and has a shape in which approximately two left and right flat plates (guide plates 13L and 13R) are connected by a bottom plate and a front plate. A rear guide shaft 14 is fixed at a position close to the rear end portion 11, and a front guide shaft 15 is fixed above the front end portion 12 between the left and right guide plates 13L, 13R.

  The pair of guide plates 13L, 13R has a substantially bilaterally symmetric outer shape, and has a height capable of maintaining the wheels W accommodated in the guide frame body 10 in a substantially vertical posture. In the present embodiment, the upper edge portions of the guide plates 13L and 13R are formed at a certain height from the rear end portion 11 toward the front end portion 12, are inclined obliquely upward from the middle, and further reach the rear end portion 12. It is formed at a certain height. The upper end corner of the entrance 11h and the upper edge of each of the guide plates 13L and 13R are designed to make it easier for the wheel W to enter by bending outward.

  The left and right guide plates 13L and 13R are erected in parallel with each other in a slightly wider state than the wheels W in order to guide and hold the bicycle wheels W. The inner width (distance D1) between the guide plates 13L and 13R is determined in consideration of the structure around the tire including the rim and spoke of the wheel W and the tire width (about 50 mm) of mountain bikes and the like that are already in widespread use. For example, it is set to a size of 55 mm or more and 65 mm or less, and is set to about 60 mm in this embodiment.

  Note that trail bikes and moped bikes equipped with wide tires of about 4 inches (100 mm or more), called fat bikes, may be excluded from the scope of application. The provided parking lock device may be installed separately.

(Wheel guide mechanism)
The wheel guide mechanism 20 includes a wheel guide 21 and a guide support shaft 22 that supports the wheel guide 21 so as to be tiltable about an axis parallel to the left-right direction (second axial direction).

  The wheel guide 21 is disposed inside the guide frame 10, and the wheel W that has entered the entrance 11 h is placed on the wheel guide 21. The wheel guide 21 is formed of a metal plate formed in a bowl shape or a channel shape having a U-shaped cross section that extends in the front-rear direction and is generally open at the top, and has a width dimension that can accommodate the wheel W. The left and right side portions of the wheel guide 21 are close to the inner surfaces of the guide plates 13L and 13R, and are configured to be tiltable around the guide support shaft 22 within a predetermined angle range.

  The guide support shaft 22 is formed of a shaft-like component extending in the left-right direction and penetrating the wheel guide 21, and both ends thereof are respectively connected to the pair of guide plates 13 </ b> L and 13 </ b> R at positions slightly lower than the rear guide shaft 14. It is fixed. The guide support shaft 22 is mounted in the vicinity of the rear end of the wheel guide 21 so that the front end of the wheel guide 21 swings in the vertical direction about the guide support shaft 22.

  When the wheel W is inserted into the entrance 11h of the guide frame 10, the wheel guide 21 takes a posture (parking position) in which the front end is slightly lowered due to the weight received from the bicycle wheel W. Normally, the vehicle is stationary with the front end slightly tilted upward (non-parking position). That is, the wheel guide mechanism 20 receives the weight of the wheel W from the non-parking position (see the solid line in FIG. 3B and FIG. 4A) that can receive the wheel W that has entered the entrance 11h. It is configured to be able to tilt around the guide support shaft 22 to the parking position tilted around 22 (see the two-dot chain line in FIG. 3B, see FIG. 4B).

  As shown in FIG. 3B, the front end side of the wheel guide 21 has an upper and lower plate surface portion 211 extending downward, and is bent back and forth at the lowermost portion of the upper and lower plate surface portion 211. A plate surface portion 212 is provided. In the upper and lower plate surface portions 211, square holes 211h (see FIG. 4A) as hooked portions described later are opened, and the front and rear plate surface portions 212 constitute contact portions described later.

(Arm movable mechanism)
The arm movable mechanism 30 includes a pair of left and right lock arms 31L and 31R and a pair of arm support shafts that rotatably support the pair of lock arms 31L and 31R around an axis parallel to the front-rear direction (first axial direction). 32L, 32R.

  The pair of lock arms 31L and 31R are disposed at substantially the middle part before and after the guide frame body 10 (the pair of guide plates 13L and 13R). The pair of lock arms 31L and 31R are housed inside lock arm covers 33L and 33R attached to the pair of guide plates 13L and 13R, respectively. The pair of lock arms 31L and 31R are metal plate members each having a pair of pressed portions 311L and 311R positioned below the wheel guide 21 and a pair of flange portions 312L and 312R positioned above the wheel guide 21. Consists of.

  The pair of arm support shafts 32L and 32R is configured by a shaft-like member extending in the front-rear direction, and penetrates the elbow portion at the lower end of the pair of lock arms 31L and 31R at a symmetrical position. Both ends of the pair of arm support shafts 32L and 32R are fixed inside the pair of lock arm covers 33L and 33R (see FIG. 1) that receive the lock arms 31L and 31R and are fixed to the guide plates 13L and 13R, respectively.

  The pair of pressed portions 311L and 311R are provided at the lower ends of the pair of lock arms 31L and 31R. The pair of pressed portions 311L and 311R are provided with lower openings 13h1 (FIGS. 3B and 4A) provided in the pair of guide plates 13L and 13R from the attachment positions (the elbow portions) of the pair of guide support shafts 32L and 32R. The arm portion protrudes inward so as to be close to each other. The pair of pressed portions 311L and 311R support the bottom of the wheel guide 21, and when the wheel guide 21 is tilted from the non-parking position to the parking position, the pair of lock arms 31L and 31R is paired with the pair of arm support shafts 32L and 32L. Rotate in opposite directions around 32R.

  The pair of collar portions 312L and 312R are provided at the upper ends of the pair of lock arms 31L and 31R, and are configured by arms that protrude inward so that the tip portions face each other. The pair of eaves 312L and 312R are guided by the rotation of the pair of lock arms 31L and 31R through the upper openings 13h2 (see FIGS. 3B and 4A) provided in the pair of guide plates 13L and 13R. The plates 13L and 13R are configured to be able to protrude from the outside to the inside (see the two-dot chain line in FIG. 3C and FIG. 4B). That is, the pair of flange portions 312L and 312R are configured to be swingable so as to advance and retract in a direction orthogonal to the approach direction of the wheel W.

  The arm movable mechanism 30 further includes a lock arm spring 34. The lock arm spring 34 is composed of a coil spring suspended from the lower ends of the pair of lock arms 31L, 31R, and the pair of pressed portions 311L, 311R are urged upward, so that the pair of spring hooks approach each other. Tow. The pair of lock arms 31L and 31R is urged by the traction force of the lock arm spring 34 in a direction in which the pair of flange portions 312L and 312R move away from each other.

  The traction force of the lock arm spring 34 is higher than the pressing force applied from the wheel guide 21 before the wheel placement to the pressed portions 311L and 311R, and the pressing force applied from the wheel guide 21 after the wheel placement to the pressed portions 311L and 311R. Is set lower. Therefore, when the bicycle is not parked, the pair of lock arms 31L and 31R retracts the pair of collars 312L and 312R to the outside of the left and right guide plates 13L and 13R, and the inner walls of the lock arm covers 33L and 33R. Is stopped in an open state (posture) in which further rotation is restricted. Thereby, the wheel guide 21 is pushed up to the non-parking position by the pair of pressed portions 311L and 311R and is stably maintained at the non-parking position.

  4A and 4B, of the left and right lock arms 31L and 31R, the right lock arm 31R is substantially in the shape of a single plate, but the left lock arm 31L has the flange 312L in front. It has a stepped shape separated in the direction. Thereby, a pair of collar parts 312L. 312R is arrange | positioned mutually spaced apart with the predetermined space | interval D2 (2nd space | interval) in the front-back direction (1st axial direction). The size of the distance D2 between the pair of flange portions 312 and 312R is not particularly limited, and is preferably set to be equal to or larger than the distance D1 between the pair of guide plates 13L and 13R. In the present embodiment, the distance D1 is set. It is set to about 60 mm, equivalent to

(Operation during parking (temporary parking))
When the user parks the bicycle Bc on the parking lock device 1, first, the rear end portion 11 (advance entrance 11 h) is moved from the rear end portion 11 (advance entrance 11 h) to the front end portion 12 so that the wheel W gets over the rear guide shaft 14 of the guide frame 10. Push the bicycle Bc toward you. The wheel W that has passed over the rear guide shaft 14 is dropped slightly downward, and then placed on the wheel guide 21 and further pushed forward, so that it contacts the front guide shaft 15 and moves further. Is limited. After the wheel W is stationary, the left and right guide plates 13L and 13R maintain the self-supporting state.

  2 to 4 show a state in which a 28-inch wheel W is accommodated in the guide frame 10 as an example. In this state, the wheel guide 21 is tilted around the guide support shaft 22 by the weight received from the wheel W to take a parking position, and the wheel W is stored between the front guide shaft 15 and the rear guide shaft 14. If the wheel is smaller than 28 inches, the play amount that the wheel W can move back and forth between the front guide shaft 15 and the rear guide shaft 14 increases. The guide spindle 22 is in a position where it does not come into contact with any size wheel.

  4B, the wheel guide 21 receives the load from the wheel W and tilts to the parking position, and the contact portion (front and rear plate surface portion 212) of the front end of the wheel guide 21 is a locking mechanism. It swings to rest on the pedestal 411 of the 40 case 41 and stops. In this state, the left and right lock arms 31L. The pressed portions 311L and 311R of 31R are respectively pressed downward, and the flange portions 312L and 312R at the tips of the left and right lock arms 31L and 31R are rotated to the closest positions indicated by two-dot chain lines in FIG. 3C. That is, the left and right lock arms 31L and 31R are closed. At this time, the flange portions 312L and 312R are approaching to a position narrower than the width dimension of the wheel W, and have advanced into the spoke region. Therefore, in this state, when the wheel W is pulled upward, the rim of the wheel W is in a positional relationship that is regulated by the flange portions 312L and 312R.

  However, since this state is not a “locked state” described later, if the bicycle Bc is lifted up or pulled forward (rearward), the left and right lock arms 31L are removed according to the weight of the wheel W being removed. , 31R (pressed portions 311L, 311R) receive the upward pressing force by the traction force of the lock arm spring 34, and the left and right lock arms 31L, 31R are opened while the wheel guide 21 is raised. Therefore, it is possible to easily pull out the bicycle Bc from the guide frame body 10. The state in which the bicycle Bc is placed instead of the “locked state” is referred to as a “temporary parking state” for convenience.

(Lock mechanism)
Next, the lock mechanism 40 will be described. FIGS. 5A and 5B are diagrams illustrating the configuration and operation of the lock mechanism 40, in which (1) and (2) of A are a left cross-sectional view and a rear view showing a state before the operation of the lock mechanism 40, respectively. B (1) and (2) are a left sectional view and a rear view, respectively, showing the operating state of the locking mechanism 40.

  The lock mechanism 40 is disposed below the front ends of the left and right guide plates 13L and 13R. The lock mechanism 40 is generally box-shaped, and includes a case 41 having a substantially L shape in side view having a pedestal portion 411 protruding rearward at the lower part.

  A metal bracket 42 is fixed inside the case 41, and a solenoid 43 having a movable iron core (plunger) 431 movable in the vertical direction is fixed to the upper portion of the bracket 42. In addition, a lock lever support shaft 440 that is axially oriented in the front-rear direction is fixed at a substantially middle position on the left and right sides of the case 41 at the middle part between the upper and lower sides of the bracket 42, and the axial direction is directed in the left-right direction below the bracket 42. The hook support shaft 450 is fixed.

  The lock lever support shaft 440 supports the lock lever 44 so as to be rotatable. The lock lever 44 is composed of a metal plate bent in a U-shape as a whole, and has front and rear plate portions 441 and 442 in which shaft holes through which the lock lever support shaft 440 passes are formed. The front plate portion 441 further has an arm portion 443 extending in the right direction, and the arm portion 443 is formed with a long hole 444 that engages with a pin 432 that fits the shaft center of the plunger 431.

  The connecting plate portion 445 that connects the front and rear plate portions 441 and 442 of the lock lever 44 is formed with a restricting portion 446 that extends downward and is further folded forward. A lever spring 46 is suspended between the pin 432 and the hook support shaft 450, and the plunger 431 is always pulled downward by the lever spring 46. When the solenoid 43 is in the attracting state, the plunger 431 rises against the pulling force of the lever spring 46, and the arm portion 443 moves upward via the pin 432 accordingly. Accordingly, the lock lever 44 is held in a posture rotated around the lock lever support shaft 440 by a predetermined angle (see FIG. 5A (2)).

  The hook support shaft 450 supports the hook 45 so as to be rotatable. The hook 45 is composed of a metal plate bent entirely in a U-shape, and has left and right plate portions 451 and 452 in which shaft holes through which the hook support shaft 450 passes are formed. The left plate portion 451 is located at the center of the left and right sides of the case 41, and a hook portion 453 and a contacted portion 454 projecting in the rearward direction are provided at two locations above and below the left plate portion 451, respectively. A hook SW operation piece 455 is further provided at the upper end of the left plate portion 451, and the hook SW operation piece 455 protrudes to the side opposite to the lock lever 44.

  The hook 45 is pulled forward by a hook spring 47. One end of the hook spring 47 is locked in a small hole provided in the middle of the left and right plate portions 451 of the hook 45, and the other end is suspended by a spring hooking portion 421 protruding forward from the bracket 42. Therefore, the hook 45 is pulled so that it always falls forward with the hook support shaft 450 as a fulcrum.

  The hook portion 453 and the contacted portion 454 that protrude in the rearward direction of the hook 45 can protrude outward from the openings 41h1 and 41h2 on the rear surface of the case 41, respectively. Normally, the hook 45 is held in a posture that is pulled forward by the hook spring 47 and rotated most forward (see FIG. 5A (1)). At this time, the abutted portion 454 protrudes upward from the opening 41 h 2 provided in the base 411 of the case 41, and most of the hook portion 453 is drawn into the case 41.

  A restricted portion 456 that engages with the restricting portion 446 of the lock lever 44 in a predetermined case is provided on the upper front side of the hook 45. The hook 45 can rotate about the hook support shaft 450 without interfering with the restricting portion 446 of the lock lever 44 when the solenoid 43 is attracted. On the other hand, as described later, after the wheel guide 21 is tilted to the parking position and the hook 45 is rotated rearward, when the suction of the solenoid 43 is released and the lock lever 44 is turned, the restricting portion 446 and the restricted portion are controlled. The interference with the portion 456 prevents the hook 45 from returning to its original posture (see FIG. 5B).

  The lock mechanism 40 further includes a lock switch (lock SW) 48 and a hook switch (hook SW) 49. The lock SW 48 is attached to the front side of the bracket 42 and has a detector 481 that detects the posture of the lock lever 44. The hook SW 49 is attached to the left side surface of the bracket 42 and has a detector 491 that detects the posture of the hook 45. The lock SW 48 and the hook SW 49 are typically configured by limit switches, and are switched ON / OFF by contact / non-contact with the lock lever 44 and the hook 45. The lock SW 48 is configured such that the detector 481 and the connecting plate portion 445 of the lock lever 44 are in contact with each other in the solenoid released state shown in FIG. 5B, and the hook SW 49 is configured so that the hook 45 is brought into contact with the wheel guide 21. The detector 491 and the hook SW operation piece 455 are configured to come into contact with each other in the state of being rotated backward (see FIG. 5B).

  FIG. 5A shows a state where the solenoid 43 is attracting. The solenoid 43 is in a suction state when energized, pulls the plunger 431 upward, and releases the suction when the power is turned off. The solenoid 43 in the energized state moves the plunger 431 to the upper end, and the lock lever 44 stops at the position most counterclockwise in FIG. 5A (2). At this time, the restricting portion 446 is separated to a position where it does not interfere with the left plate portion 451 of the hook 45. Since the detector 481 of the lock SW 48 is slightly separated from the plate surface of the lock lever 44 when the lock lever 44 is in the stopped posture, the lock SW 48 is OFF. Further, since the hook SW operation piece 455 of the hook 45 is also slightly separated from the detector 491 of the hook SW49, the hook SW49 is OFF.

  When the wheel W is placed on the wheel guide 21 in the suction state of the solenoid 43 as described above, the wheel guide 21 rotates toward the parking position in the accommodation direction indicated by the arrow A1 in FIG. 5A. The front / rear plate surface portion (contact portion) 212 of the guide 21 stops at a position where it contacts the pedestal portion 411 of the case 41. Then, the contacted portion 454 of the hook 45 is pushed downward by the contact portion 212, the hook 45 is rotated backward against the traction force of the hook spring 47, and the hook portion 453 is moved upward and downward of the wheel guide 21. It will advance into the square hole 211h of the plate surface portion (hooked portion) 211 (see FIG. 5B). This state is a temporary parking state as described above, and if the wheel guide 21 rotates in the disengagement direction, the hook can return to its original posture by the pulling force of the hook spring 47.

  FIG. 5B shows a state where the suction of the solenoid 43 is released (solenoid released state). When the energization of the solenoid 43 is turned off, the plunger 431 of the solenoid 43 is released from suction, and protrudes downward by its own weight and the traction force of the lever spring 46. Then, the lock lever 44 fitted to the pin 432 turns clockwise in FIG. 5A (1), and the lower restricting portion 446 can advance into the space on the front side of the hook 45. Therefore, when the solenoid 43 is released after the wheel guide 212 is rotated in the accommodation direction, the restriction portion 446 of the lock lever 44 is positioned further to the front side of the restricted portion 456 of the hook 45 as shown in FIG. 5B. Thus, the turning motion of the hook 45 toward the original posture is restricted. Therefore, even if the wheel guide 21 is returned in the disengagement direction indicated by the arrow A2 in FIG. 5B when the solenoid 43 is in the released state, the engagement between the hook portion 453 and the hooked portion 211 (square hole 211h) is maintained. For this reason, the wheel guide 21 cannot be returned to the separation direction. Hereinafter, this state is also referred to as “locked state”.

  In the state of FIG. 5B, the detector 491 of the hook SW49 is pushed by the hook SW operation piece 455, and therefore the hook SW49 is ON. Further, the detector 481 of the lock SW 48 is pushed by the connecting plate portion 445 of the lock lever 44, and therefore the lock SW 48 is ON.

[Bicycle parking system connection configuration]
FIG. 6 shows an electrical block of the bicycle parking system 100 of the present embodiment.

  The settlement machine 6 includes a CPU (Central Processing Unit) 611, a memory 612, and the like, and the CPU 611 executes a program recorded in the memory 612, whereby the operation of the settlement machine 6 as a whole is controlled. The CPU 61 and the memory 612 include a display screen device 601, an operation key group 602, an audio output device 603, an external communication unit 604, an input / output unit 605, an RTC (Real Time Clock) 606, a staff call button 607 via a bus and an interface. , A coin selector 608, a bill reader 609, a coin payout device 610, and the like. The input / output unit 605 is multidrop-connected to the control unit 51 of each parking lock device 1.

  Each parking lock device 1 has a control unit 51. The control unit 51 is electrically connected to the solenoid 43, the hook SW49, the lock SW48, the LED (Light Emitting Diode) 52, etc., and controls energization to the solenoid 43 and the LED 52 and the release thereof. The ON / OFF state of SW49 is detected. The control unit 51 is typically configured by a computer and includes a storage unit that records an ID corresponding to its own parking lock device number.

  LED52 is attached to the main-body part 50 of each parking lock device 1, for example (refer FIG. 5), and has a function which displays visually the information regarding the availability of the parking lock device 1, etc. to a user.

[Operation of parking lock device]
Hereinafter, the details of the control unit 51 will be described together with the operation of the parking lock device 1.

  FIG. 7 shows an operation flow of the parking lock device 1 of the present embodiment.

  The solenoid suction state of FIG. 5A is the initial state, and at that time, both the hook SW49 and the lock SW48 are OFF. The LED 52 is ON and is lit. In this example, lighting of the LED 52 indicates that the parking lock device 1 can be used. As a result, in a state where power is not supplied due to a power failure, the LED 52 is turned off, and the solenoid 43 is not in the suction state, so that it can be understood that it cannot be used.

  First, the user inserts the bicycle Bc into the vacant parking lock device 1. The wheel guide 21 rotates in the accommodation direction A1 (parking position) and the contacted portion 454 of the hook 45 is pushed. When the control unit 51 detects that the hook SW is turned on (step 1), it starts measuring the service time (step 2). The service time can be set by the checkout machine. For example, if it is possible to park for up to 5 minutes without charge adjustment, the service time will be 5 minutes. If the operation is to control only long-time parking, the service time will be about 30 minutes. Good. Of course, it is possible not to provide a service time, but when it is arranged in parallel on a street, it is preferable to provide the service time to some extent in consideration of the entrance of a person described later.

  The control unit 51 repeats monitoring whether the hook SW is turned off while monitoring the service time (step 3) (step 4). If the user pulls out the bicycle during the service time and the wheel guide 21 is moved in the disengagement direction A2 (non-parking position), the hook SW49 is turned off, and the process is terminated at that time. On the other hand, if the bicycle is still in the temporary parking state even after the service time has elapsed, the control unit 51 releases the solenoid 43 (step 5). The control unit 51 immediately monitors whether the lock SW 48 is turned on (step 6), and if it is on, turns off the LED 52 (step 7). If the lock SW 48 is not turned on even after a lapse of a certain time in step S6, an error occurs (not shown) and the processing should be stopped.

  After turning off the LED (the light is turned off), the control unit 51 starts measuring the parking time (step 8). After this, since it is in the “locked state”, it can be returned to the “unlocked state” by paying a fee (can be settled at 0 yen).

  The control unit 51 monitors whether the payment has been completed (step 9). The control unit 51 calculates a fee from the parking time of the device following the input of the number of the corresponding parking lock device 1, and sucks the solenoid when the settlement is completed (step 10). Next, the control unit 51 immediately monitors whether the lock SW 48 is turned off (step 11), and if it is turned off, the LED 52 blinks (step 12). This is because the user can immediately recognize the parking lock device 1 that has already been settled by blinking the LED.

  Thereafter, the control unit 51 monitors whether or not the hook SW 49 is turned off (step 13). During this time, the parking lock device 1 is in the “unlocked state”, which is the same as returning to the temporary parking state again. Therefore, if the user pulls out the bicycle in this state and the wheel guide 21 moves in the disengaging direction A2 (non-parking position), the hook SW49 is turned off. Then, the control unit 51 turns on (lights) the LED 52 and ends the process (step 14).

  If the service time of step S3 has elapsed before the hook SW 49 is turned off in step S13, the operation of step S5 may be repeated again. That is, once payment is completed and parking is continued as it is, it may be returned to the locked state again.

  In the parking lock device 1 configured as described above, it is assumed that anything other than wheels is placed on the wheel guide 21 by mischief, and surveillance cameras are often installed around the street. However, mischievous acts are suppressed, but children and infants may come and go between adults when people can enter along the streets.

  Here, the foot width size of the men's shoes is approximately 79 mm to 122 mm, and the foot width size of the women's shoes is approximately 76 mm to 112 mm, whereas the foot width size of the children's shoes is 40 mm to 109 mm. It is known that there are (refer to the general association of feet and shoes and the Health Council website). In particular, in a shoe having a foot length size of about 10.5 cm to 15 cm that seems to be suitable for infants, the foot width is only 60 mm with a normal width E size. By the way, the size of the shoes of a 3-year-old child who would be able to wander around various places alone instead of walking around is set to 13-15 cm.

  When an infant enters the vicinity of the parking lock device 1, it is necessary to consider entering various places by wearing shoes having a foot length of 15 cm and a foot width of less than 60 mm. The weight detection level of the wheel guide 21 set in the parking lock device 1 is, for example, about 7 kg in the case of a light foldable bicycle. Since one of them is placed on the wheel guide 21, when 3.5 kg, which is half the weight of the bicycle, is placed on the wheel guide 21, the wheel guide 21 needs to be pressed to operate correctly.

  On the other hand, if the average height of a 3-year-old child is approximately 96 cm to 97 cm and the average weight is 13 to 14 kg, the 3-year-old child will not operate even if stepped on, but a lightweight bicycle will be detected. A solution in weight balance is not possible. Further, as described above, in order to cover bicycle parking of a bicycle having a tire width of around 50 mm such as a mountain bike, the width of the guide frame 10 needs to be about 60 mm, and this width may be reduced. Not realistic.

  Therefore, in the parking lock device 1 of the present embodiment, the flange portions 312L and 312R of the pair of lock arms 31L and 31R that sandwich the wheel W from both sides of the guide frame 10 are parallel to the guide plates 13L and 13R (front and rear). Direction).

  As shown in FIGS. 4A and 4B, the right lock arm 31R has a substantially single plate configuration, while the left lock arm 31L has a lower half of the lock arm 31L symmetrical to the right lock arm 31R. Although it has a single sheet shape, it is formed in a substantially Z-shaped bent state that is once bent at a right angle in the middle in the vertical direction and bent again at a right angle at a position separated by about 60 mm. In this configuration, as shown in FIG. 3C, when viewed from the front-rear direction, the left and right lock arms 31L, 31R are almost symmetrical, but only the upper flange portions 312L, 312R are spaced by a distance D2 (60 mm) in the front-rear direction. It is separated.

  In the locked state with this configuration, the flange portions 312L and 312R that are spaced apart from each other in the spoke area inside the wheel W advance from the left and right, but any of the flange portions 312L and 312R However, since it advances into the spoke area, it does not contact the tire rim. If the bicycle Bc is to be pulled out in this state, the tire rim is limited by the flange portions 312L and 312R which are separated from each other in the front-rear direction, and the front and rear direction of the tire is determined by the left and right guide plates 13L and 13R. Can be tilted only within the range of the distance between the guide plates 13L and 13R (distance D1, 60 mm in this example), so that the left and right collars 312L and 312R are positioned in the same front-rear direction and locked. As with the wheel lock device, the wheels W are reliably locked.

  8A and 8B are a top view and a left side view showing a state in which a model of the foot size of the infant is inserted into the parking lock device 1.

  As shown in FIG. 8A, if the size of an infant shoe SH is 60 mm or less in width, the shoe SH enters (depresses) with the foot length direction substantially parallel to the inside (distance D1) of the left and right guide plates 13L and 13R. )be able to. At that time, even if the φ50 mm cylindrical portion F assuming the ankle portion is just hooked on the collar portions 312L and 312R of the lock arms 31L and 31R in the front-rear direction, it is not sandwiched from the left and right.

  As described above, according to the present embodiment, a leg of a passerby (especially an infant) who accidentally entered the inside of the guide frame body 10 is sandwiched between the right and left hooks 312L and 312R of the lock arms 31L and 31R. Risk can be avoided as much as possible.

  Further, in the parking lock device 1 of the present embodiment, the distance (interval D2) in which the flange portions 312L and 312R of the left and right lock arms 31L and 31R are separated in the front-rear direction is the left and right guide plates 13L of the guide frame 10. , 13R is equal to or larger than the distance (distance D1). Therefore, since the left and right flange portions 312L and 312R face each other and do not come into contact with the object from the left and right with respect to an object other than the wheel W that may enter between the guide plates 13L and 13R. Even if a passerby who wears shoes whose width is narrower than the distance between the guide plates 13L and 13R enters his / her foot, the danger of being caught between the left and right heel portions 312L and 312R is avoided.

  Further, in the parking lock device 1 of the present embodiment, the separation distance between the left and right guide plates 13L, 13R is 60 mm (55 m or more and 65 mm or less), and the separation distance in the front-rear direction between the left and right flange portions 312L, 312R is the above-described distance. It is 60 mm, which is equivalent to the distance. That is, in consideration of a foot of a size that can be stepped on while reducing the width of the guide frame 10 (the distance between the guide plates 13L and 13R) as much as possible while allowing for bicycle parking. The above separation distances of the portions 312L and 312R are set.

  Therefore, among passers-by, adults or non-adults of about junior high school age or more, the width of the guide frame 10 is smaller than the size of the shoes, and at least a user who is assumed to use the parking lock device 1 is in the guide frame 10. Never step in. On the other hand, in the case of an infant among passers-by, there is a risk that it can be stepped into the inside of the guide frame 10 with the size of the shoes for infants as described above, but the separation distance between the left and right heel portions 312L and 312R Is provided at the same distance as the distance between the guide plates 13L and 13R, so that the danger that an infant's foot is caught in the buttocks 312L and 312R of the lock arms 31L and 31R can be avoided as much as possible.

  As described above, according to the present embodiment, in the parking lock device 1 of the parking system 100 that controls parking management by locking or unlocking the wheel of a two-wheeled vehicle, particularly a bicycle in an unmanned management state, a passerby other than the bicycle Even if the wheel guide 21 or the like is stepped on by mistake, it is possible to eliminate the risk of injury and to realize such a parking lock device 1 considering safety.

<Second Embodiment>
9A and 9B are a top view and a left side view showing a configuration of a parking lock device according to another embodiment of the present invention.
Hereinafter, the configuration different from the first embodiment will be mainly described, and the same configuration as the first embodiment will be denoted by the same reference numeral, and the description thereof will be omitted or simplified.

  The parking lock device 101 of the present embodiment is common to the first embodiment in that it includes a guide frame 110, a wheel guide mechanism 20, an arm movable mechanism 130, and a lock mechanism 40. The configurations of 110 and the arm movable mechanism 130 are different from those of the first embodiment.

  In the present embodiment, the guide frame 110 has recesses 16L and 16R provided in the left and right guide plates 13L and 13R, respectively. The left and right recesses 16L and 16R are provided at positions facing the left and right flange portions 312L and 312R in the left and right direction (second axial direction), respectively. That is, one recess 16R is provided at the position of the guide plate 13R facing the one flange 312L in the left-right direction, and the other recess 16L is provided at the position of the guide plate 13L facing the other flange 312R in the left-right direction. It is done.

  The left and right recesses 16L, 16R are partially cylindrical (semi-cylindrical) that can cut out a part of the guide plates 13L, 13R facing the flanges 312L, 312R and cover the notches 17L, 17R from the outside. ). The width in the front-rear direction of the recesses 16L, 16R may be at least about 60 mm, and the amount of recess (depth in the left-right direction) should be at least 60 mm or more away from the tips of the flanges 312L, 312R in the protruding state facing each other. For example, it is about 30 mm.

  The upper and lower lengths of the recesses 16L and 16R need to be open, but the lower ends are lower than the heights of the flanges 312L and 312R, for example, to the height of both frames of the wheel guide 21. It only has to be extended.

  Next, the arm movable mechanism 130 will be described. FIG. 10 is a perspective view of a main part showing details of the arm movable mechanism 130 in the parking lock device 101 of the present embodiment.

  In the present embodiment, the structures of the collar portions 312L and 312R are devised. That is, when viewed from the inner side of the ends of the flange portions 312L and 312R, the metal plate is folded back by 180 degrees in opposite directions in the front-rear direction so that the end portion of the metal plate is not exposed to the inside. Portions 312L and 312R are configured. As a result, the tips of the buttocks 312L and 312R are curved without being sharp, and even if the buttocks 312L and 312R accidentally come into contact with the foot of an infant who has stepped into the guide frame 110, there is a risk of injury. Can be avoided.

  In the present embodiment, the left and right lock arms 131L and 131R each have a U-shaped shape that is open upward, in which plate surfaces that are separated in the front-rear direction are connected at the bottom. The arm holes 32L and 32R are penetrated through the through-hole portions 361L, 361R, 362L, and 362R formed on the plate surfaces that are separated from each other before and after that, and the left and right opening / closing operations are performed.

  Of these, the flange 312L of the left lock arm 131L is provided at the upper end of the front plate surface 352L, and the flange 312R of the right lock arm 131R is provided at the upper end of the rear plate surface 351R. The left and right pressed parts 311L and 311R are provided at the lower ends of the rear plate surfaces 351L and 351R, and the lock arm spring 34 is suspended between the rear plate surfaces 351L and 351R.

  The through-hole portions 361L, 361R, 362L, 362R have shapes that allow relative movement in the front-rear direction of the left and right flange portions 312L, 312R with respect to the guide frame 110. That is, the through-hole portions 361L and 361R formed in the rear plate surfaces 351L and 351R are in a loosely fitted state slightly larger than the diameter of the arm support shafts 32L and 32R. Further, the through-hole portions 362L and 362R formed in the front plate surfaces 352L and 352R are formed as long holes in the vertical direction and are configured to be fitted to the arm support shafts 32L and 32R.

  Thus, the front plate surfaces 352L and 352R can swing in the front-rear direction with the through-hole portions 361L and 361R formed in the rear plate surfaces 351L and 351R as fulcrums. Further, the through-hole portions 361L and 361R formed in the rear plate surfaces 351L and 351R are formed by round holes slightly larger than the diameters of the arm support shafts 32L and 32R, so that the traction force of the lock arm spring 34 is increased. The relative position between the received left and right pressed parts 311L and 311R is stably held.

  In this case, the upper opening 13h2 through which the flange portions 312L and 312R of the guide plates 13L and 13R are inserted is formed as a square hole widened so as to have a wide gap in the front-rear direction with respect to the thickness of the flange portions 312L and 312R. The Thereby, the predetermined movable range along the front-back direction of the collar parts 312L and 312R is ensured.

  As described above, in the parking lock device 101 of the present embodiment, the left and right lock arms 131L and 131R are formed of metal plates, and the left and right flange portions 312L and 312R are respectively opposite to each other in the front-rear direction. Consists of folded parts folded in the direction. For this reason, it is difficult to be injured even if the buttocks 312L and 312R come into contact with an infant's foot accidentally entering the guide frame 110, while the bicycle wheel rim cannot be easily removed. Secured.

  Further, in the parking lock device 101 of the present embodiment, the left and right lock arms 131L and 131R are configured such that the collar portions 312L and 312R are movable in a direction (front-rear direction) parallel to the guide plates 13L and 13R. As a result, even if the foot is caught between the lock arms 131L and 131R, the heel portions 312L and 312R move and escape in the front-rear direction, so that the foot is hardly caught and is not easily injured. Moreover, even if it abuts against the spokes of the wheels, it can move in the traveling direction and escape, so that the situation where the hooks 312L and 312R hit the spokes and do not lock can be avoided, and the bicycle wheels are securely locked.

  In the present embodiment, the lock arm spring 34 can exert a traction force in a neutral state with respect to the swing in the front-rear direction in both the left and right lock arms 131L and 131R. In this case, the above-described back-and-forth swinging is realized without a complicated component configuration, but a member for holding the neutral position is separately provided so that the lock arms 131L and 131R can be reliably opened and closed at the neutral position. It may be added.

  Further, in the parking lock device 101 of the present embodiment, a substantially semi-cylindrical shape corresponding to the positions of the collar portions 312L and 312R is formed on the side walls of the guide plates 13L and 13R opposite to the advancing and retreating directions of the collar portions 312L and 312R. Concave portions 16L and 16R are formed. Thereby, even if the buttocks 312L and 312R come into contact with the foot of an infant accidentally stepped into the guide frame 110, the foot can easily escape to the recesses 16L and 16R, and injury can be avoided more easily. .

  In this configuration, the recesses 16L and 16R are provided in the guide plates 13L and 13R. However, the notches 17L and 17R are simply formed by notching the portions of the guide plates 13L and 13R. The widths of the portions 17L and 17R may be suppressed to such an extent that the wheels do not escape, or an appropriate inclined portion may be provided so that the wheel that moves back and forth does not get caught at the ends of the notches 17L and 17R.

  As mentioned above, although embodiment of this invention was described, this invention is not limited only to the above-mentioned embodiment, Of course, a various change can be added.

  For example, in the above embodiment, the lock arms 31L, 31R, 131L, and 131R are configured as a pair of left and right, but the present invention is not limited to this. For example, one hook portion is provided on one side and two hook portions are provided on the other side. These may be arranged apart from each other in the direction parallel to the guide frame. When the recesses 16L, 16R or the notches 17L, 17R are formed on the guide plate as in the second embodiment, the recesses or notches are located at positions facing the three flanges, respectively. It may be formed.

  Further, in the above embodiment, the plunger 431 is configured to move up and down by energizing the solenoid 43 constituting the lock mechanism 40 or releasing the energization, but the solenoid 43 may be a latching solenoid or the like, for example. Thus, a solenoid that can maintain the retracted state of the plunger without maintaining the energized state may be used. Thereby, the power consumption of the parking lock device in the non-parking state can be suppressed.

  Furthermore, in the above embodiment, the lock arms 31L, 31R, 131L, and 131R are all made of a metal plate. For example, the whole of the collar portions 312L and 312R or only the tip portion thereof can be appropriately elastically deformed. It may be constituted by. Thereby, even if the buttocks abut on the foot of the infant that has been stepped over the guide frame body while ensuring the locked state of the wheels, it is possible to suppress the injury.

  In the parking lock device according to the present invention described above, the configurations of the guide frames 10 and 110, the wheel guide mechanism 20, and the lock mechanism 40, and the overall configuration and operation flow of the parking system are the configurations of the embodiment. The essential technology of the present invention can be implemented in a bicycle parking system and a bicycle parking lock device having various configurations.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used for a parking lock device used in a parking system that controls parking management by locking or unlocking a wheel of a two-wheeled vehicle, particularly a bicycle in an unmanned management state.
