JP 2001-001966 A (Detailed description of the invention, drawings)

  However, in the conventional wheel lock device described in Patent Document 1, when the locking arm is locked and the wheel is locked, the ratchet arm meshes with the ratchet piece, and the operation of the locking arm is restricted. Therefore, in order to release the restraint of the locking arm, it is necessary to release the meshing relationship between the ratchet piece and the ratchet arm by operating the solenoid.

  Therefore, when a bicycle or the like parked is removed from the wheel lock device, if the control mechanism of the wheel lock device breaks down, the casing covering the locking arm and the drive mechanism of the wheel lock device is removed. Thereafter, the bicycle or the like cannot be removed from the wheel lock device unless a jig or the like is inserted into the drive mechanism and the meshing relationship between the ratchet piece and the ratchet arm is released. Thus, in the wheel lock device described in Patent Document 1, when the wheel lock device breaks down, the state of restraining the wheel of the bicycle cannot be easily released. There is a problem that it takes a lot of time to escape.

  The present invention has been made in view of the above problems, and provides a wheel lock device that can easily release the restraint of a wheel when various control means or operation means in the wheel lock device break down. With the goal.

  In order to solve the above-described problem, a wheel lock device of the present invention includes a frame member having two opposing wall surfaces, a lock arm that locks a wheel disposed between the two wall surfaces, and two wall surfaces. The lock arm is pivotally supported at the part, and has a support shaft that can be attached to and detached from the frame member by pushing and pulling out, and a drive source that swings the lock arm around the support shaft. is there.

  According to this configuration, since the support shaft that supports the lock arm can be attached to and detached from the frame member by pushing and pulling out, the control mechanism and the like inside the wheel lock device can be operated in a state where the wheel of a bicycle or the like is restrained. Even if the bicycle breaks down and it becomes impossible to escape, the restraint of the wheel can be released by a simple operation of pulling out the support shaft, and the bicycle or the like can be easily removed from the apparatus. Therefore, unreasonable restraint is not prolonged and convenient for the user. In addition, the administrator can be relieved and the burden on management is reduced. Furthermore, since the mechanism can be simplified, the cost can be reduced and the apparatus can be miniaturized.

  In another aspect of the invention, the wheel lock device includes a frame member having two wall surfaces facing each other, a lock arm for locking a wheel disposed between the two wall surfaces, and a lock arm on the two wall surfaces. It has a support shaft that is swingably supported and can be manually removed after the apparatus is completed, and a drive source that swings the lock arm about the support shaft.

  According to this configuration, since the support shaft that supports the lock arm can be manually removed after the device is completed, the control mechanism or the like inside the wheel lock device breaks down while the wheel of the bicycle or the like is restrained. Even when it is impossible to escape the bicycle or the like, the wheel restraint can be released by a simple operation of manually removing the support shaft, and the bicycle or the like can be easily escaped from the apparatus. Therefore, unreasonable restraint is not prolonged and convenient for the user. In addition, the administrator can be relieved and the burden on management is reduced. Furthermore, since the mechanism can be simplified, the cost can be reduced and the apparatus can be miniaturized.

  In addition to the above-described invention, the wheel lock device according to another invention is provided with two lock arms and two support shafts so as to form a pair. It is supported to rotate in the direction. When configured in this manner, the structure is simple and the lock arm swings around a pair of left and right support shafts, so that it is possible to avoid applying an excessive load to one of the support shafts. It becomes.

  In addition to the configuration of the invention described above, the wheel lock device according to another invention is provided with a hole in the lock arm, and the lock arm is arranged in an X shape so that the hole overlaps, A cam driven by a drive source is inserted into the two holes. In such a configuration, a simple motor is used as a drive source, and the two lock arms can be driven by rotating one cam, thereby simplifying the mechanism.

  In addition to the configuration of the invention described above, a wheel lock device according to another invention includes a spring for locking the support shaft on the surface of the wall surface portion on the back side in the insertion direction of the support shaft among the opposing wall surface portions. The member is attached. In this case, the spring member locks the support shaft so that the support shaft is fixed to the wall surface on the back side, and the fixed portion is not easily touched and is safe. This is preferable in terms of surface quality.

  Furthermore, in the wheel lock device according to another invention, in addition to the configuration of the invention described above, when the spring member inserts the distal end side of the support shaft into the through hole provided in the wall surface portion to which the spring member is attached, It is bent against the urging force, and the support shaft can be further inserted. In such a configuration, the support shaft is locked by the biasing force of the spring member by a very simple operation of inserting the support shaft into the through hole.

  In addition to the above-described invention, the wheel lock device of another invention is provided with an engaging groove for engaging the spring member over the entire circumference of the support shaft at the tip end side of the support shaft. Is. In this case, when the support shaft is inserted into the through-hole, a part of the spring member is fitted into the engagement groove by the biasing force of the spring member, and the support shaft is more firmly engaged. It is possible to stop.

  In addition to the above-described invention, the wheel lock device according to another invention is such that the pushing of the support shaft is completed by the spring member being fitted into the engagement groove by its urging force. In such a configuration, the push-in completion position is when the spring member is inserted into the groove, so that there is no risk of the spring member jumping out of the engagement groove. In addition, when the support shaft is inserted into the through hole and the push-in is completed, the support shaft is positioned.

  In a wheel lock device according to another invention, in addition to the above-described invention, the spring member has a substantially U-shaped shape having two leg portions that hold the support shaft by its urging force. In this case, the support shaft is urged from both sides so as to be sandwiched between the two leg portions, so that the insertion is smoothly and more firmly locked to the wall surface portion. It becomes.

  In addition to the above-described invention, the wheel lock device according to another invention is such that the substantially U-shaped curved portion of the spring member abuts on a corner where the side surface and the bottom surface of the frame member intersect, and any of the side surface and the bottom surface is provided. Is fixed in a slanting manner. When configured in this way, the spring member is fixed so that its substantially U-shaped curved portion abuts against the corner where the side surface and the bottom surface of the frame member intersect. Even when the spring member is bent and a load is applied to the spring member, the corner portion receives the load, thereby preventing the spring member from being displaced due to the load.

  In addition to the above-described invention, the wheel lock device according to another invention is installed on the wall surface by the fixing member via the restraining member that restrains the movement of the support member in the insertion direction of the spring member. Is sandwiched between two legs forming a substantially U-shaped spring member. In such a configuration, the fixing member receives the two leg portions of the spring member, so that the substantially U-shaped shape can be maintained. Further, due to the presence of the restraining member, the displacement of the spring member in the insertion direction of the support shaft due to the insertion of the support shaft can be prevented.

  In addition to the above-described invention, the wheel lock device according to another invention is formed with a female screw portion that can engage with a male screw or a male screw portion that can engage with a female screw at the other end of the support shaft. Is. With this configuration, the tool can be engaged with the support shaft by screw engagement. In addition, when configured in this way, only an administrator of a device who possesses a tool having a male screw or a female screw and knows how to operate and use the tool spindle can form the tool on the spindle. By inserting the female screw portion or the male screw portion, the support shaft can be pulled out from the apparatus. Therefore, since a general person who does not have such a special tool cannot release the restraint of the wheel, unauthorized escape (just escape) and theft of a bicycle or the like can be prevented.

  In addition to the above-described invention, the wheel lock device according to another invention is such that the female screw portion or the male screw portion engages with a male screw or a female screw that can be screwed in by counterclockwise rotation. In such a configuration, only an administrator of a device having a very special tool having a male screw or a female screw that can be screwed in counterclockwise rotation can use the tool as a support shaft. By inserting the formed female screw portion or the male screw portion, the support shaft can be pulled out from the apparatus. Therefore, since a general person who does not have such a very special tool cannot release the restraint of the wheel, unauthorized escape (just escape) and theft of a bicycle or the like can be prevented.

  In addition to the above-described invention, the wheel lock device according to another invention can be engaged with the female screw portion or the male screw portion by inserting a tool having a male screw or a female screw from the outside of the casing surrounding the device. In this way, it is arranged at a position facing the insertion hole provided in the housing. In such a configuration, even when the wheel lock device is surrounded by the housing and disposed as part of the parking system, the support shaft is pushed into and pulled out of the wheel lock device from the outside of the housing. Is possible.

  In the present invention, even if the wheel lock device breaks down when the wheel is restrained, the restraint of the wheel can be easily released.

  Hereinafter, a wheel lock device according to an embodiment of the present invention will be described with reference to the drawings. The wheel lock device will be described as a part of the parking system.

  FIG. 1 is a perspective view showing a bicycle parking system according to an embodiment of the present invention.

  The parking system according to this embodiment mainly includes a low rack unit 1, a high rack unit 2, the same number of wheel locking devices 3 as the total number of low rack units 1 and high rack units 2, and a collecting unit 4. Have. In this embodiment, a bicycle parking system having one low rack unit 1 and one high rack unit 2 will be described as an example. However, there are two or more low rack units 1 and two high rack units 2 respectively. Also good. In addition, since this embodiment has one low rack unit 1 and one high rack unit 2, there are two vehicle locking devices 3.

  The low rack unit 1 includes a low rail wheel rail 21, a guide member 22, and a roller 23.

  The low-rack wheel rail 21 has a bottom portion 21a and two side portions 21b and 21b. The width of the bottom portion 21a is formed wider than the width of the bicycle wheel 101, and the length of the bottom portion 21a is formed in a long shape that is substantially the same as the length of the bicycle. In addition, the length of the bottom 21a may be formed in a long shape to the extent that a front wheel or a rear wheel of the bicycle is placed. The two side portions 21b and 21b are respectively provided in a shape that stands along the long end of the bottom portion 21a and substantially perpendicular to the bottom portion 21a. Thereby, the wheel rail 21 for low racks is formed in a substantially U-shaped cross section. Such a low-rack wheel rail 21 can be formed by bending a long steel plate at both ends in the short direction to the same side.

  The low rack wheel rail 21 is fixed to the rear frame 5 at one end in the longitudinal direction. Further, the other end side of the low-rack wheel rail 21 in the longitudinal direction is fixed to the front frame 6 with the wheel lock device 3 interposed therebetween. Thereby, the wheel rail 21 for low racks is fixed to the inclined posture in which the other end side is lifted rather than the one end side in the longitudinal direction. Hereinafter, the other end side where the low-rack wheel rail 21 is lifted is referred to as a front end of the low-rack wheel rail 21, and this one end side is referred to as a rear end.

  The guide member 22 of the low rack unit 1 is provided so as to follow the shape of the wheel rail 21 for low rack and to protrude upward from the wheel rail 21. The guide member 22 of the low rack unit 1 is configured such that the height from the low rack wheel rail 21 to the upper edge of the guide member 22 is the same as or slightly lower than the radius of the bicycle wheel. Is formed.

  The roller 23 of the low rack unit 1 has a rotating shaft attached between two side portions 21b and 21b of the wheel rail 21 for the low rack via a pedal 71 which will be described later. It is rotatably arranged in the longitudinal direction of 21a. The roller 23 is disposed at the center of the low rack wheel rail 21 in the longitudinal direction or at a position slightly closer to the tip of the wheel rail 21 than the center. The roller 23 is attached in a shape protruding upward from the bottom 21a. The bottom 21a on the tip side of the roller 23 is formed to be horizontal with respect to the ground, and the bottom 21a is an inclined surface that gradually increases in height from the rear end of the wheel rail 21 to immediately before the roller 23. Is formed.

  A bicycle is pushed into the low rack unit 1 from the rear end side of the low-rack wheel rail 21 that is lowered. When the front wheel of the bicycle exceeds the roller 23, the bicycle does not return to the rear end side even if the hand is released from the bicycle, and the bicycle is supported while standing against the guide member 22. . Thereby, the bicycle can be parked while standing in the low rack unit 1.

  The high rack unit 2 includes a high rail wheel rail 31, a guide member 32, and a roller 33.

  The wheel rail 31 for high racks has a bottom part 31a and two side parts 31b and 31b. Moreover, the wheel rail 31 for high racks has a shape in which the wheel rail 21 for low racks is further lengthened and bent at a steep angle at the center in the longitudinal direction.

  The high rack wheel rail 31 is fixed to the rear frame 5 with a support column 7 having a low end in the longitudinal direction. Further, the other end side in the longitudinal direction of the wheel rail 31 for the high rack is fixed to the front frame 6 with the wheel lock device 3 and the high column 8 interposed therebetween. Thereby, the wheel rail 31 for high racks is fixed to the largely inclined posture in which the other end side is lifted rather than the one end side in the longitudinal direction. Hereinafter, the other end side where the wheel rail 31 for high racks is lifted is described as the front end of the wheel rail 31 for high racks, and this one end side is described as the rear end.

  The guide member 32 of the high rack unit 2 has the same shape as the guide member 22 of the low rack unit 1, and is provided so as to follow the shape of the wheel rail 31 for the high rack and to protrude above the wheel rail 21. It is what The guide member 32 of the high rack unit 2 is such that the height from the high rack wheel rail 31 to the upper edge of the guide member 32 is the same as or slightly lower than the radius of the bicycle wheel. Is formed.

  The roller 33 of the high rack unit 2 has the same configuration as the roller 23, and is rotatable between two side portions 31b and 31b of the wheel rail 31 for the high rack via a pedal 71 described later, and It is arranged so as to have the same positional relationship as the roller 23. The reason why the rollers 23 and 33 are attached to the pedal 71 described later is to prevent unauthorized parking. That is, when the rollers 23 and 33 are directly attached to the side portions 21b, 21b, 31b and 31b, the bicycle is supported by the guide member 22 and the roller 23 or by the guide member 32 and the roller 33, and the pedal 71 is lowered. It becomes easy to cause a state where there is no illegal parking. However, if the rollers 23 and 33 are attached to the pedal 71, when the rollers 23 and 33 are pushed, the pedal 71 is also pushed reliably, and parking can be detected. Further, the roller 33 is closer to the tip than the bent portion of the wheel rail 31 for the high rack, and the position in the longitudinal direction of the wheel rail 31 for the high rack or slightly closer to the tip of the vehicle rail 31 than the center. It is arranged.

  A bicycle is pushed into the high rack unit 2 from the rear end side of the lower high-rack wheel rail 31. Then, when the bicycle is pushed in until the front wheel of the bicycle gradually rises up the bottom 31a on the rear end side where the bicycle has a steep angle and the front wheel of the bicycle exceeds the roller 33, the bottom 31a of the front wheel of the bicycle is horizontal. And the roller 33 prevents the returning operation. For this reason, even if the hand is released from the bicycle, the bicycle is not pushed back, and the bicycle is supported while standing against the guide member 32. As a result, the bicycle can be parked while standing on the high rack unit 2.

For this reason, as compared with the case where the support shafts 51 and 52 are fixed by screwing or the like, the support shafts 51 and 52 can be easily detached from the frame constituent members 46 and 47 by inserting the tool 56 into the female screw portion 51a. Will be able to. When the support shafts 51 and 52 are pushed in, the support of the support shafts 51 and 52 with respect to the frame constituent members 46 and 47 is provided in the grooves 51d and 52d formed in the support shafts 51 and 52 after the frame constituent member 47. The engaging springs 51g and 52g arranged on the end side are engaged, and the abutting portion 51b is brought into contact with the vertical portion 46b of the frame constituting member 46.

  As shown in FIG. 5 (A), the locking spring 51g has a U-shape, and is formed with a curved base portion 51h and a protruding portion in the same direction from the root portion 51h. It is comprised from two leg parts 51i and 51i. The locking spring 51g is attached to the rear end side of the frame constituting member 47 so that the root portion 51h abuts both the side surface portion 46d and the bottom surface portion 47a and is inclined with respect to both of them. ing. In addition, the locking spring 51g is arranged at the corner 47v of the component member 47 so that the base 51h is in contact with both the side surface portion 46d and the bottom surface portion 47a, and is slightly more than the washer 51l and the locking spring 51g. The hole 47j is screwed through the thick collar so as to be freely bent, and the vicinity of the openings of the leg portions 51i and 51i is screwed into the hole 47i so as to be freely bent through the collar slightly thicker than the washer 51j and the locking spring 51g. It is done in the form. The axial disengagement of the locking spring 51g on the base side is prevented by the washer 51l. In addition, as shown in FIG. 5A, the opening side of the locking spring 51g sandwiches the collar 51i, 51i fixed by screws 51k inserted into the holes 47i from both sides. For this reason, the two legs 51i, 51i are always urged from both sides of the collar fixed by the screw 51k inserted into the hole 47i, and the open end side of the locking spring 51g by the washer 51j. This prevents the axial direction from being removed.

Similarly to the locking spring 51g, the locking spring 52g has a U-shape, and includes a curved root portion 52h and two leg portions 52i and 52i. Similarly to the locking spring 51g, the locking spring 52g is screwed into the hole 47p so that its root portion 52h can be bent at a corner 47w via a washer 52l and a collar slightly thicker than the locking spring 52g. At the same time, the vicinity of the openings of the leg portions 52i and 52i is screwed to the hole 47n so as to be freely bent through a collar slightly thicker than the washer 52j and the locking spring 52g.

  As shown in FIG. 5 (A), the state of the locking springs 51g, 52g before the support shafts 51, 52 are inserted is the locking spring 51g and the leg portions 51i, 51i of the locking spring 52g and the leg portions 52i, 52i is a state in which both sides of the collar fixed by the screw 51k and the collar fixed by the screw 52k are sandwiched. At this time, the leg portions 51i and 51i and the leg portions 52i and 52i urge the collar fixed by the screw 51k and the collar fixed by the screw 52k from both sides. Further, the leg portions 51i, 51i and the leg portions 52i, 52i are arranged on the outer peripheral side of the through hole 47h and the through hole 47m so as to partially overlap each other, and the centers of the through hole 47h and the through hole 47m are arranged. Located on both sides of the axis.

  In a state where the support shafts 51 and 52 are inserted into the through holes 46g, 47h, 46h, and 47m, and the peripheral side surfaces of the cylindrical portions 51f and 52f of the support shafts 51 and 52 are in contact with the locking springs 51g and 52g, respectively. As shown in FIG. 6A, the leg portions 51i and 51i and the leg portions 52i and 52i are opened away from both sides of the collar fixed by the screw 51k and the collar fixed by the screw 52k. . In this state, when the support shafts 51 and 52 are inserted into the through holes 46g, 47h, 46h, and 47m, the respective cylindrical portions 51f and 52f are in contact with the leg portions 51i and 51i and the leg portions 52i and 52i, and the leg portions 51i. , 51i and the legs 52i, 52i are bent outward against the urging force.

  In a state where the support shafts 51 and 52 are completely inserted into the through holes 46g, 47h, 46h, and 47m, as shown in FIG. 7A, the space between the frame component member 47 and the frame component member 48 is formed. The leg portions 51i and 51i and the leg portions 52i and 52i of the locking springs 51g and 52g are inserted into the protruding grooves 51d and 52d. In this way, the leg portions 51i, 51i and the leg portions 52i, 52i enter the groove portions 51d, 52d so as to sandwich the groove portions 51d, 52d from both sides thereof, thereby penetrating the frame constituting member 47 of the support shafts 51, 52. Removal from the holes 47h and 47m is prevented. The locking springs 51g and 52g are washers 51j and 52j arranged on the opening side thereof, and the opening side of the locking springs 51g and 52g is prevented from coming off in the axial direction. The lock springs 51g and 52g are prevented from coming off in the axial direction by washers 51l and 52l arranged at 52h. Note that displacement of the vertical portion 47b in the direction parallel to the plane is prevented by the bottom surface portion 47a and the side surface portions 46d on both sides.

  When the tool 56 having both male threads is inserted into the female threaded portions 51a and 52a and engaged with both of the support shafts 51 and 52, when the tool 56 is pulled strongly toward the distal end, the locking springs 51g and 52g are momentarily moved. It is taken out when the bulge lock is released. On the other hand, when it is desired to insert the tool 56, the tool 56 can be inserted even when the tool 56 is not used. That is, by inserting the support shaft 51 into the through hole 46g, fulcrum holes 54c and 54c of the lock arm 54 described later, and the through hole 47h, the conical portion 51e enters between the leg portions 51i and 51i of the locking spring 51g. . When the support shaft 51 is pushed in strongly, the locking spring 51g swells outward for a moment and then enters the groove 51d. As a result, the support shaft 51 is locked by the locking spring 51g and is prevented from coming off. Similarly, when the support shaft 52 is pushed strongly, the locking spring 52g enters the groove portion 52d of the support shaft 52, thereby preventing the support shaft 52 from coming off.

  Two lock arms 53 and 54 are disposed between the vertical portion 46 b of the frame constituent member 46 and the vertical portion 47 b of the frame constituent member 47. The lock arm 53 and the lock arm 54 are arranged and used in pairs. The lock arm 53 and the lock arm 54 are each formed in a substantially half-ring shape (hereinafter referred to as a semi-annular shape). The lock arm 53 and the lock arm 54 are installed so as to cross in an X shape (see FIG. 9). When both the lock arms 53 and 54 face each other and the tips thereof are brought into contact with each other, a substantially ring having a diameter of the distance between the contact portion and the eccentric cam 61 is formed. These lock arms 53 and 54 are formed of metal members. However, it may be formed of a polycarbonate resin. Polycarbonate resin is a kind of engineering plastic and has a characteristic that it is not easily damaged even when a large force is applied. In addition, engineering plastics such as polycarbonate resin have a feature that the material is softer than metal, so that it is difficult to damage the bicycle even if it hits the bicycle. For this reason, engineering plastics other than polycarbonate resin or other hard resin materials may be used for the lock arms 53 and 54.

  The lock arms 53 and 54 have exactly the same shape and can be used interchangeably. The lock arm 53 includes a central lock plate 53a and two side plates 53b and 53b which are arranged on both sides of the lock plate 53a and fixed to the lock plate 53a. Similarly, the lock arm 54 includes a lock plate 54a and side plates 54b and 54b. A fulcrum hole 53c is provided on one end side of the side plates 53b and 53b, and a support shaft 52 is inserted into the fulcrum holes 53c and 53c. Similarly, fulcrum holes 54c and 54c are provided in the side plates 54b and 54b, and the support shaft 51 is inserted therein. The lock arm 53 rotates and swings about the support shaft 52 for the fulcrum, and the lock arm 54 rotates and swings about the support shaft 51 for the fulcrum. In addition, each rotation fulcrum becomes a central axis of the support shafts 51 and 52.

  Long holes 53d and 53d are provided in the approximate center of the side plates 53b and 53b, and long holes 54d and 54d are also provided in the approximate center of the side plates 54b and 54b. An eccentric cam 61 to be described later is inserted into the long hole 53d on the distal end of the long holes 53d and 53d and the long hole 54d on the distal end side of the long holes 54d and 54d.

  The lock arms 53 and 54 are configured such that when the wheel 101 is forced to escape, the gap G between the other ends is further narrowed. That is, the supporting shafts 51 and 52 that serve as the pivotal fulcrum of the lock arms 53 and 54, the position of the tip 55 of the lock arm that serves as the action point, and the force applied when the parked car tries to escape. The relationship with the direction is devised. Details of this point will be described when the operation of the bicycle parking system is described.

  The eccentric cam 61 is rotationally driven by a motor 62 serving as a drive source and a speed reduction unit 63, and these constitute a drive unit. The drive unit is fixed to the vertical portion 48 a of the frame component 48 and is disposed in the internal space of the frame component 48. This fixing is performed by inserting an elastic member made of a cylindrical rubber material into the three holes 48f of the vertical portion 48a so that the inside and both ends of the hole 48f protrude and pass through the center of the cylindrical elastic member. This is done by inserting a screw. In this way, by attaching the motor 62 and the speed reduction unit 63 to the vertical portion 48a serving as the chassis via the elastic member, it is possible to transmit power without using a shaft coupling. As described above, since the fixing is performed through the elastic member, even if the output shaft 63b of the speed reduction unit 63 and the support portion 61b on the rear end side of the eccentric cam 61 are displaced or both or one of them is inclined. It is possible to absorb errors and the like caused thereby.

  As shown in FIGS. 4 and 8, the eccentric cam 61 includes a support portion 61a on the front end side, a support portion 61b on the rear end side that is aligned with the support portion 61a, and both support portions 61a and 61b. On the other hand, it has a columnar cam portion 61c whose center is eccentric, and a columnar engagement recess 61d into which the output shaft 63b of the speed reduction unit 63 is inserted. The engagement portion recess 61d is formed on the end side of the support portion 61b, and a screw for integrating the output shaft 63b and the eccentric cam 61 is inserted into a portion surrounding the engagement recess 61d. The screw hole is formed perpendicular to the axial direction.

  The motor 62 includes a cylindrical motor housing 62a, an output shaft 62b rotatably supported by the motor housing 62a, a rotor (not shown) fixed to the output shaft 62b, and the rotor and the motor housing 62a. And a stator (not shown) disposed. When a magnetic field is generated in the rotor by energization, the rotor and the output shaft 62b are rotated by a magnetic attractive force or a repulsive force between the stator magnetic field and the rotor magnetic field. When energization is lost, the rotation of the rotor and output shaft 62b stops.

  The reduction unit 63 has a gear group (not shown) in the unit case 63a and a reduction output shaft 63b. The gear group includes a plurality of gears, and includes at least a gear that rotates together with the output shaft 62b of the motor 62 and a gear that rotates together with the reduction output shaft 63b. And the deceleration rate by this deceleration unit 63 should just be about 1/1000-1/50. For example, when the deceleration rate is 1/100, the output shaft 62b of the motor 62 rotates 100 times, so that the deceleration output shaft 63b rotates once. In addition, it can replace with a gear group and can make it obtain a desired deceleration rate with the pulley group comprised by a some pulley. However, when a pulley is used, it is preferable to use a gear group because slippage is inevitably generated between the pulley and the belt that spans the pulley.

  When the deceleration output shaft 63b rotates, the eccentric cam 61 rotates around the support portions 61a and 61b. Further, along with this rotation, the outermost portion of the cam portion 61c of the eccentric cam 61 and the portion farthest from the center of rotation is located in the long holes 53d and 54d of the lock arms 53 and 54 of the support portions 61a and 61b. Rotates in a plane perpendicular to the central axis. The moving range in which the eccentric cam 61 moves up and down is set such that the distance between the center axis of the support portions 61a and 61b and the outer peripheral portion farthest from the rotation center is x, the center axis of the support portions 61a and 61b, and the rotation center If the distance from the nearest outer peripheral portion to y is y, xy corresponds to it. The greater the xy, the wider the range of movement that moves up and down.

  A detection plate 64 is fixed to the support 61b on the rear end side of the eccentric cam 61 by screws. The front end of the detection plate 64 is bent toward the motor 62, and the front end portion is detected by sensors 65 and 66 described later.

  The drive unit is fixed to the frame member 45 so that the rotation center of the eccentric cam 61 and the center axis of the deceleration output shaft 63b are aligned. As a result, when the eccentric cam 61 rotates about the support portions 61 a and 61 b, the lock arms 53 and 54 are predetermined about the support shafts 51 and 52 according to the movement accompanying the rotation of the cam portion 61 c of the eccentric cam 61. Oscillates within the angular range.

  Note that the angle range of the rocking of the lock arms 53 and 54 is determined according to the size of the cam portion 61c of the eccentric cam 61 and the like. That is, as the difference between the distance x and the distance y, which is the degree of eccentricity in the cam portion 61c, is increased, the angular range of rocking of the lock arms 53 and 54 can be expanded. In this embodiment, when the outer peripheral portion of the cam portion 61c of the eccentric cam 61 is at the lowest position, both the lock arms 53, 54 are opened, that is, both the lock arms 53, 54 becomes an open state. At this time, the interval G between the other end portions (= upper end) of the lock arms 53 and 54 becomes the largest and becomes the interval G1.

  As shown in FIG. 10, the position where the eccentric cam 61 rotates approximately 180 degrees from the state shown in FIG. 9 is the state where both lock arms 53 and 54 are closest, that is, both the lock arms 53 and 54 are closed. Become. At this time, the interval G between the other end portions (= upper end) of the lock arms 53 and 54 is the smallest and becomes the interval G2.

  Thereby, the lock arm 53 and the lock arm 54 can be opened and closed by rotating the motor 62 of the drive unit by energization. Note that the other end of the lock arm 53 and the other end of the lock arm 54 do not have to be in strict contact with each other when the lock arm 53 is most closed. It is only necessary that the distance between the other end of the lock arm 53 and the other end of the lock arm 54 when closed most is narrower than the width of the bicycle wheel.

  Further, a closed position detection sensor 65 and an open position detection sensor 66 are disposed in the internal space of the frame constituent member 47 together with the sensor substrate 67. The sensor substrate 67 is fixed to the frame constituent member 48. The closed position detection sensor 65 and the open position detection sensor 66 are optical sensors that optically detect the position of the detection plate 64. The optical sensor has a light emitting element and a light receiving element, and is a sensor that detects a change in a light receiving state in the light receiving element of light from the light emitting element. In addition, there are two types of optical sensors, a reflective type and a transmissive type, depending on the relative positions of the light emitting element and the light receiving element, and either type may be adopted.

  For example, when a transmissive optical sensor is used as the closed position detection sensor 65, the other end of the lock arm 53 and the other end of the lock arm 54 are in contact with or close to each other, that is, the cam portion 61 c of the eccentric cam 61. The closed position detection sensor 65 is arranged so that the detection plate 64 that rotates integrally with the eccentric cam 61 when the outer peripheral portion is at the highest position is positioned between the light emitting element and the light receiving element of the closed position detection sensor 65. . When the other end of the lock arm 53 and the other end of the lock arm 54 are separated, the detection plate 64 is not positioned between the light emitting element and the light receiving element of the closed position detection sensor 65. It is necessary to install. The closed position detection sensor 65 outputs a detection signal when the light receiving element stops receiving light.

  When a transmissive optical sensor is used as the open position detection sensor 66, the state where the other end of the lock arm 53 is farthest from the other end of the lock arm 54, that is, the outer peripheral portion of the cam portion 61c of the eccentric cam 61 is The open position detection sensor 66 is arranged so that the detection plate 64 is positioned between the light emitting element and the light receiving element of the open position detection sensor 66 when the lowest position is reached. When the other end of the lock arm 53 and the other end of the lock arm 54 are not farthest apart, the open position is set so that the detection plate 64 is not located between the light emitting element and the light receiving element. It is necessary to install the detection sensor 66. The open position detection sensor 66 outputs a detection signal when the light receiving element stops receiving light.

  The wheel lock device 3 has a pedal 71. As shown in FIGS. 2 and 8, the pedal 71 has a substantially rectangular pedal body 71a and a pedal link plate 71b disposed at one end in the longitudinal direction of the pedal body 71a. The pedal body 71a rotates at the other end in the longitudinal direction around a fixed shaft 71c disposed between the two side surfaces 21b and 21b of the wheel rail 21 and the two side surfaces 31b and 31b of the wheel rail 31. It is installed as possible. Thereby, the pedal 71 can rotate centering on one end thereof. The pedal link plate 71b is provided with a link portion 71d protruding to the rear end side. The link portion 71d is engaged with the one end portion 73a side of the detection shaft 73, and the detection shaft 73 is rotated in accordance with the vertical movement of the pedal 71.

  The pedal link plate 71b penetrates the through-hole 75 (see FIG. 8) formed in the wheel rails 21, 31 in a state where the pedal body 71a is disposed on the wheel rails 21, 31, and the wheel rails 21, It protrudes to the back side of 31. And as mentioned above, the link part 71d is formed in the front-end | tip part which protrudes to the back side of 21 and 31 of the pedal link board 71b. A winding spring 74 as an urging member is disposed at one end 73 a of the detection shaft 73. Therefore, for example, when the pedal body 71a is pushed down by the load of the wheel 101 from a state where one end of the pedal body 71a is lifted, the one end 73a side of the detection shaft 73 is also pushed down. The detection shaft 73 is rotated by the pressing force, and the detection plate 72 is also rotated with this rotation.

  The detection plate 72 includes a detection plate main body 72a formed in a substantially rectangular shape, and a sensor plate portion 72b that is bent toward the motor 62 side at the front end side of the detection plate main body 72a. The detection plate main body 72a is fixed to the detection shaft 73 at one end in the longitudinal direction. The detection shaft 73 is composed of a single shaft member, and has one end portion 73a that engages with the link portion 71d, and a support portion 73b around which the winding spring 74 is wound and supported by the frame member 45. The one end 73a is orthogonal to the length direction of the wheel rails 21 and 31, and is arranged in a substantially horizontal direction. The support portion 73b is arranged in parallel to the length direction of the wheel rails 21 and 31.

  The winding spring 74 has a coil part 74a and a pair of hook parts 74b formed at both ends of the coil part 74a. One hook portion 74 b of the pair of hook portions 74 b is hung on the engaging portion 73 a of the detection shaft 73. The other hook part 74 b in the pair of hook parts 73 b is suspended in a hole 46 r provided in the frame component member 46. As a result, a force in the direction of lifting the pedal 71 is biased to the detection shaft 73. Further, when the bicycle is not riding on the pedal 71 due to the urging force of the winding spring 74, one end of the pedal body 71a attached to the wheel rails 21, 31 is lifted from the wheel rails 21, 31 ( (See FIG. 8).

  In order to detect the position of the detection plate 72, a press detection sensor 75 is provided as a parking detection sensor. The position of the sensor plate portion 72b in a state where one end of the pedal body 71a is in contact with or close to the wheel rails 21, 31 is detected. As the press detection sensor 75, for example, a transmission type optical sensor may be used. The press detection sensor 75 outputs a detection signal when the light receiving element of the transmissive optical sensor receives light. In this embodiment, the press detection sensor 75 is disposed on the sensor substrate 67 together with the closed position detection sensor 65 and the open position detection sensor 66. In addition, the sensor substrate 67 is fixed to the frame constituent member 48 described above, and is disposed in a space surrounded by the frame constituent member 47, and in a direction perpendicular to the surface of the upper surface portion 41a of the housing 41. It is arranged.

  FIG. 11 is a block diagram showing a control system of the collecting unit 4 and the parking system in FIG. FIG. 12 is a view showing a state in which the bicycle wheel 101 is placed on the wheel rails 21 and 31. FIG. 13 is a diagram showing an initial state of the wheel lock device 3 when it is going to be forcibly escaped, and is a diagram showing a part seen through from the front end side, and FIG. 14 is a diagram when it is going to be forcibly escaped It is a figure which shows the state of the wheel lock apparatus 3 after force is added to FIG. 2, and is a figure shown in the state which saw through partially from the front end side. FIG. 15 is a diagram illustrating an operation of attaching the tool 56 to the support shaft 52 when the support shaft 52 is pulled out from the wheel lock device 3, and FIG. 16 is a diagram illustrating an operation of pulling out the support shaft 52 from the wheel lock device 3. is there. FIG. 17 is a diagram illustrating a state in which a part of the support shaft 52 is pulled out from the wheel lock device 3 and seen from the front end side. FIG. It is a figure shown in the state which saw through a part from the front end side of the state which pulled out.

  The collecting unit 4 includes a timer 81 that outputs time information, a recording unit 82 that stores data, an input key 83, a display unit 84, a fee collection unit 85 into which bills and money are inserted, and the vehicle lock device 3. A motor drive unit 86 for energizing the motor 62 and a microcomputer. By executing a parking control program (not shown), the microcomputer performs a parking detection unit 91, a lock control unit 92 as an energization control unit, a fee calculation unit 93, a deposit metering unit 94, and an energization control unit. The unlocking control unit 95 is realized. The parking control program can be stored in the recording unit 82 using a computer-readable recording medium such as a compact disk (not shown) or a transmission medium such as an electric communication line as a medium.

  When a detection signal is input from the press detection sensor 75, the parking detection unit 91 reads time information at the input timing of the detection signal from the timer 81, and causes the recording unit 82 to record the read time information as a parking start time. Is.

  The lock control unit 92 causes the motor drive unit 86 to start energization after the detection signal is input to the parking detection unit 91. In addition, when the detection signal is input from the closed position detection sensor 65, the locking control unit 92 stops energization by the motor driving unit 86.

  The period from when the detection signal is input to the parking detection unit 91 until the locking control unit 92 starts energization of the motor drive unit 86 can be set to an arbitrary time. That is, as soon as a detection signal is input to the parking detection unit 91, the locking control unit 92 may be set to start energization of the motor drive unit 86. For example, after the detection signal is input to the parking detection unit 91, 20 The locking control unit 92 may be set to start energization of the motor driving unit 86 after a predetermined time such as minutes elapses.

  When the low rack unit 1 or the high rack unit 2 to be cleared is specified by, for example, a unique identification number for each rack unit, the charge calculation unit 93 starts parking of the rack unit from the recording unit 82. In addition to reading the time, the current time information is read from the timer 81, and the charge is calculated based on the time difference therebetween. Further, the fee calculation unit 93 displays the calculated fee on the display unit 84.

  The deposit metering unit 94 calculates a fee input to the fee collection unit 85. Then, the deposit weighing unit 94 notifies the unlocking control unit 95 when the charged fee is equal to or higher than the fee calculated by the fee calculating unit 93.

  The unlock control unit 95 causes the motor drive unit 86 to start energization when notified from the deposit metering unit 94. In addition, when the detection signal from the open position detection sensor 66 is input, the unlocking control unit 95 stops energization by the motor driving unit 86.

  Next, the overall operation of the bicycle parking system according to this embodiment will be described.

  The person who has ridden the bicycle places the bicycle on the wheel rail 21 for the low rack, for example (see FIG. 12A). Specifically, the bicycle can be placed on the low rack wheel rail 21 by pushing the bicycle from the lower rear end side of the low rack wheel rail 21 toward the front end side. At this time, since the front wheel of the bicycle gets over the roller 23 provided via the pedal 71 in the middle of the wheel rail 21 for the low rack, the bicycle is held so as not to fall back. Moreover, since the guide member 22 is provided in the wheel rail 21 for low racks, even if the hand is released from the bicycle, the bicycle does not fall down and fall from the wheel rails 21 for low rack. The front wheel of the bicycle parked in the low rack unit 1 is placed on the pedal 71.

  The pedal 71 is pushed down by the placement of the front wheel, that is, the weight of the parked bicycle. When the pedal 71 is pushed down, the link portion 71d pushes down the one end 73a side of the detection shaft 73. Since the detection shaft 73 rotates when the one end 73a side is pressed down, the detection shaft 73 rotates when the pedal 71 is pressed down. The detection plate 72 fixed integrally with the detection shaft 73 rotates together with the detection shaft 73. When the sensor plate portion 72b of the detection plate 72 is removed from between the light emitting element and the light receiving element of the press detection sensor 75, the press detection sensor 75 outputs a detection signal.

  When the detection signal from the press detection sensor 75 is input to the parking detection unit 91, the parking detection unit 91 reads time information at the input timing of the detection signal from the timer 81, and uses the read time information as the parking start time. As shown in FIG.

  Further, the lock control unit 92 causes the motor drive unit 86 to start energizing the motor 62 after the detection signal is input to the parking detection unit 91. The output shaft 62b of the motor 62 starts to rotate by energization by the motor drive unit 86, and the eccentric cam 61 also starts to rotate by the rotation obtained by reducing the rotation of the output shaft 62b. As the eccentric cam 61 rotates, the lock arm 53 and the lock arm 54 rotate in the closing direction. When a detection signal is input from the closed position detection sensor 65, the locking control unit 92 stops energization by the motor drive unit 86.

  In a state where the detection signal from the closed position detection sensor 65 is output, the other end of the lock arm 53 and the other end of the lock arm 54 are in contact with or in close proximity to each other. In addition, an annular ring is formed when the other ends of the lock arms 53 and 54 come into contact with each other or close to each other, so that the annular ring and the rim of the wheel 101 mounted on the pedal 71 are chained with a slight gap. It becomes a connected state. That is, as shown in FIG. 12 (B), the wheel 101 is wrapped with the lock arm 53 and the lock arm 54. As a result, even if the bicycle is to be pulled out from the low rack unit 1, the bicycle wheel 101 cannot be pulled out because the rim of the bicycle wheel 101 is caught by the lock arm 53 and the lock arm 54. That is, the bicycle is locked to the low rack unit 1.

  However, sometimes there are those who try to escape illegally. The forced escaper tries to pull out the bicycle with great effort. In the conventional wheel lock device, in such a case, this force acts to open the tips of the lock arms, so that the distance between the tips of both lock arms becomes slightly larger. As a result, an illegal forced escape person puts more power, the drive mechanism of the lock arms 53 and 54 and the lock arms 53 and 54 is broken, and the forced escape succeeds. In addition, if there is a backlash or deflection of the parts, the gap G may become an opening width that allows the wheel 101 to slip through only by trying to pull out the bicycle with a little force.

  On the other hand, as shown in FIG. 13, in the wheel lock device 3 of the present embodiment, when the wheel 101 is lifted by attempting a forced escape (just escape), the lock arm 53 is pushed in the direction indicated by the arrow A. A clockwise moment M1 is received around the support shaft 52 in FIG. This is a direction to strengthen the restraint. This moment M1 is generated by a force MA in the direction of arrow A generated by the wheel 101. That is, the force MA can be decomposed into a force MA1 on a line connecting the center of the support shaft 52, which is a pivotal fulcrum of the lock arm 53, and an action point, and a force MA2 orthogonal to the straight line. This force MA2 produces a clockwise moment M1. Thus, if the shape of the lock arm 53 and the fulcrum of the lock arm 53 are formed so that the component force MA2 acting in the right direction in FIG. 13 is generated with respect to the lock arm 53, the lock arm 53 moves in the closing direction. Will be.

  Similarly, the lock arm 54 is also pushed in the direction indicated by the arrow B, and receives a moment M <b> 2 in a direction that strengthens the restraint around the support shaft 51. This moment M2 is also generated by the force MB in the direction indicated by the arrow B generated by the wheel 101. That is, the force MB can be decomposed into a force on a line connecting the center of the support shaft 51 that is the rotation fulcrum of the lock arm 54 and the action point, and a force orthogonal to the straight line. This orthogonal force generates a counterclockwise moment M2 in FIG. Thus, if the shape of the lock arm 54 and the fulcrum of the lock arm 54 are formed so that a component force acting in the left direction in FIG. 13 is generated with respect to the lock arm 54, the lock arm 54 moves in the closing direction. It will be.

  As a result, even if forced escape (just escape) is attempted, the lock arm 53 and the lock arm 54 are closed (see FIG. 14), so the wheel 101 cannot escape. At this time, the interval G is further narrowed to become the interval G3.

  When the lock arm 53 and the lock arm 54 are moved in the closing direction, the cam follower portion surrounding the elongated holes 53d and 54d, that is, the contact portion with the eccentric cam 61 is separated from the eccentric cam 61. That is, a space g is formed between the lock arms 53 and 54 and the eccentric cam 61. As a result, since the force of forceful escape is not applied to the motor 62, the eccentric cam 61, the support portions 61a and 61b of the eccentric cam 61, the vertical portion 47b of the frame constituting member 47, etc., the risk of damaging them is greatly reduced.

  Next, the bicycle departure operation will be described. A person who wants to leave the bicycle from the previous low rack unit 1 operates the input key 83 to designate the low rack unit 1. The charge calculation unit 93 reads the parking start time of the low rack unit 1 designated by the input key 83 from the recording unit 82 and reads the current time information from the timer 81. The current time at this time is the parking end time. Then, the fee calculation unit 93 calculates a parking fee based on the time difference between the parking start time and the parking end time, and causes the display unit 84 to display the calculated parking fee.

  A person who wants to leave the bicycle inputs the parking fee displayed on the display unit 84 to the fee collection unit 85. The deposit metering unit 94 notifies the unlocking control unit 95 when the fee input to the fee collection unit 85 exceeds the fee calculated by the fee calculation unit 93. If the input fee exceeds the parking fee, the deposit metering unit 94 may return the difference to the fee collection unit 85.

  The unlocking control unit 95 immediately starts energization of the motor driving unit 86 upon receiving a notification from the deposit weighing unit 94. When the motor drive unit 86 is energized, the output shaft 62b of the motor 62 starts to rotate in the same direction as when locked, and the eccentric cam 61 also starts to rotate by rotating the output shaft 62b decelerated. As the eccentric cam 61 rotates, the lock arm 53 and the lock arm 54 rotate in the opening direction. When the detection signal from the open position detection sensor 66 is input, the unlocking control unit 95 stops energization by the motor driving unit 86.

  In the state where the detection signal is output from the open position detection sensor 66, the other ends of the lock arms 53 and 54 are in the most separated state. Therefore, a person who wants to leave the bicycle can pull out the bicycle from the low rack unit 1.

  The operation of the bicycle parking system when the bicycle is parked in the high rack unit 2 is the same as that when the bicycle is parked in the low rack unit 1 described above, and the description thereof is omitted.

  Next, when the lock arm 53 and the lock arm 54 are closed, the control mechanism of the wheel lock device 3, the collecting unit 4, etc. break down, and the lock arm 53 becomes unable to escape from the wheel lock device 3. A method of releasing the restraint of the lock arm 54 will be described.

  As described above, since the support shaft 51 and the support shaft 52 can be pushed and pulled out, the restraint of the lock arm 53 and the lock arm 54 is released by extracting the support shaft 51 and the support shaft 52 from the wheel lock device 3. be able to. First, a case where only the support shaft 52 is pulled out will be described.

  In the state where the lock arm 53 and the lock arm 54 are closed, the support shaft 51 and the support shaft 52 are in a state of being inserted (pushed in), so that the abutting portions 51b and 52b of the support shafts 51 and 52 are It is in contact with the vertical portion 46 b of the frame constituting member 46.

  That is, from this state, the support shaft 52 is pulled out using the tool 56. The tool 56 includes a male screw portion 56a that can be screwed by rotating counterclockwise, and a grip portion 56b that is a portion that is gripped by hand. Then, as shown in FIG. 15, the tool 56 is inserted from the notch hole 41 h on the front end side of the housing 41, and the front end is brought into contact with the female screw portion 52 a of the support shaft 52. Then, the tool 56 is inserted into the female screw portion 52a of the support shaft 52 while rotating the tool 56 in the arrow D direction which is the counterclockwise direction. By rotating the tool 56 in the direction indicated by the arrow D, the male screw portion 56 a engages with the female screw portion 52 a, and the tool 56 is inserted into the support shaft 52.

  In a state where the tool 56 is inserted into the support shaft 52, the support shaft 52 is still inserted into the wheel lock device 3. That is, the support shaft 52 includes a through hole 46h formed in the frame constituent member 46, a fulcrum hole 53c formed in the lock arm 53, and a frame constituent member, as in the case of the support shaft 51 shown in FIG. It penetrates through a through hole 47 m formed in 47. Then, as shown in FIGS. 7A and 7B, the distal end portion of the support shaft 52 has a leg portion of the locking spring 52g in a groove portion 52d protruding into the space between the frame constituent member 47 and the frame constituent member 48. 52i and 52i enter and are locked.

  From the state in which the tool 56 is inserted into the support shaft 52 in this way, the support shaft 52 is pulled out in the direction indicated by arrow E, that is, in the distal end side, as shown in FIG. When a force is applied in the direction in which the support shaft 52 is pulled out, as shown in FIG. 6A, the leg portions 52i and 52i of the locking spring 52g bend outward against the biasing force and fit into the groove portion 52d. The leg portions 52i and 52i are separated from both sides of the collar fixed by the screw 52k and are opened.

  When the support shaft 52 is further pulled out, the support shaft 52 moves away from the locking spring 52g and is completely pulled out from the wheel lock device 3 as shown in FIG. Accordingly, the leg portions 52i and 52i of the locking spring 52g are moved in a direction to sandwich the collar fixed by the screw 52k by the urging force, and are fixed by the screw 52k as shown in FIG. It will be in contact with the collar on both sides. In this state, the leg portions 52i, 52i urge the collar fixed by the screw 52k from both sides.

  Through the state as described above, the support shaft 52 is completely pulled out from the wheel lock device 3.

  When the support shaft 52 is pulled out, the restraint of the lock arm 53 is released. When the restraint is released, the lock arm 53 rotates in the opening direction with its weight in the vicinity of the central axis M of the cam portion 61c of the eccentric cam 61 as a fulcrum. The rotation of the lock arm 53 is performed such that the inner peripheral surface 53h of the long hole 53d is in contact with the outer peripheral surface 61d of the cam portion 61c. When the corner portion 53g of the lock arm 53 comes into contact with the inner peripheral surface of the cover portion 41g of the housing 41, the opening operation of the lock arm 53 is completed, and the lock arm 53 is most opened as shown in FIG. It becomes a state. In this state, if the gap G4 between the tip of the lock arm 54 and the cover portion 41g is wider than the width of the bicycle wheel 101, the bicycle can be escaped from the wheel lock device 3. Since the interval G4 is usually wider than the width of the wheel 101, the bicycle can be escaped. However, sometimes it cannot be escaped. In that case, the other support shaft 51 is further pulled out.

  Next, a case where both the support shaft 51 and the support shaft 52 are pulled out will be described. In this case, since it is difficult to assume that both the support shaft 51 and the support shaft 52 are pulled out at the same time, either the support shaft 51 or the support shaft 52 is pulled out first, and then the remaining one is pulled out. Here, a case where the support shaft 52 is first extracted and then the support shaft 51 is extracted from the relationship with the above description will be described.

  When the support shaft 52 is pulled out, the lock arm 53 is in the most open state as shown in FIG. Thereafter, when the support shaft 51 is pulled out, the male screw portion 56a is inserted into the female screw portion 51a of the support shaft 51 while rotating the tool 56 in the counterclockwise direction as in the case described above. In this state, as in the case described above, the support shaft 51 is completely inserted into the wheel lock device 3 as shown in FIG. 7, and the end of the support shaft 51 is engaged by the locking spring 51g. It has been stopped.

  When the support shaft 51 is pulled out from this state, the locking spring 51g is shown in FIG. 5 through a state in which the leg portions 51i and 51i are opened apart from both sides of the collar fixed by the screw 51k as shown in FIG. Each of the leg portions 51i and 51i is in a state of sandwiching the collar fixed by the screw 51k. When the support shaft 51 is completely pulled out, the lock arm 54 opens in the opening direction.

  The opening operation of the lock arm 54 when the support shaft 51 is completely pulled out is similar to the opening operation of the lock arm 53 when the support shaft 52 is pulled out. That is, the lock arm 54 rotates in the opening direction with its own weight as a fulcrum in the vicinity of the central axis M of the cam portion 61c of the eccentric cam 61. The rotation of the lock arm 54 is performed in such a manner that the inner peripheral surface 54h of the long hole 54d is in contact with the outer peripheral surface 61d of the cam portion 61c, as in the opening operation of the lock arm 53 when the support shaft 52 is pulled out. . When the corner portion 54g of the lock arm 54 comes into contact with the inner peripheral surface of the cover portion 41g of the housing 41, the opening operation of the lock arm 54 is completed, and as shown in FIG. Is in its most open state. In this state, the lock arm 53 and the lock arm 54 completely enter the cover portions 41g and 41g, so that the bicycle can be surely escaped from the wheel lock device 3.

  On the other hand, when inserting the support shaft 51 or the support shaft 52 into the wheel lock device 3, first, the lock arm 54 or the lock arm 53 is rotated in the closing direction by hand, and the fulcrum hole 54c or the lock arm 54 of the lock arm 54 is locked. The position of the fulcrum hole 53c of the arm 53 is matched with the position of the through hole 46g or the through hole 46h of the frame constituting member 46. Then, the support shaft 51 or the support shaft 52 is inserted toward the through hole 46g or the through hole 46h. When the insertion is completed, push it in with your hand. The tool 56 may be engaged with the support shaft 51 or the support shaft 52 while rotating in the counterclockwise direction, and then the tool 56 is strongly pressed to complete the pressing. In this case, it is necessary to pull out the tool 56 from the support shaft 51 or the support shaft 52 while rotating the tool 56 in the clockwise direction. As described above, the support shaft 51 or the support shaft 52 is inserted into the wheel lock device 3.

  In the wheel lock device 3 according to the present embodiment configured as described above, the support shafts 52 and 51 that support the lock arms 53 and 54 are pushed and pulled out to pull out the frame member 45, specifically, the frame. It can be attached to and detached from the constituent members 46 and 47. Therefore, even when the wheel 101 of the bicycle or the like is restrained by the lock arms 53 and 54, even if the control mechanism inside the wheel lock device 3 or the collecting unit 4 or the like breaks down and the bicycle cannot be escaped, The restraint of the wheel 101 can be released by a simple operation of pulling out one or both of the support shafts 51 and 52, and the bicycle can be easily escaped from the wheel lock device 3. Therefore, unreasonable restraint is not prolonged and convenient for the user. In addition, the administrator can be relieved and the burden on management is reduced. Furthermore, since the support shafts 51 and 52 can be attached and detached by a simple mechanism, the cost is reduced and the wheel lock device 3 can be downsized.

  Further, in the wheel lock device 3 according to this embodiment, the lock arms 53 and 54 and the support shafts 52 and 51 are provided in pairs so as to form a pair, and the support shafts 52 and 51 make a pair of left and right swings. However, they are supported so as to rotate in opposite directions. Accordingly, the wheel lock device 3 has a simple structure and the lock arms 53 and 54 swing around the support shafts 52 and 51 provided in a pair of left and right, so that one of the support shafts 52 or 51 Excessive load can be avoided.

  Further, in the wheel lock device 3 according to this embodiment, the lock arms 53, 54 are provided with the long holes 53d, 54d, and the lock arms 53, 54 are arranged in an X shape so that the long holes 53d, 54d overlap. An eccentric cam 61 driven by a motor 62 is inserted into the two long holes 53d and 54d. Therefore, the two lock arms 53 and 54 can be driven by rotating the eccentric cam 61 using the simple motor 62 as a drive source, and the mechanism is simplified. Further, the lock arms 53 and 54 are crossed so that the long holes 53d and 54d overlap each other, and the eccentric cam 61 is inserted into the long holes 53d and 54d so that the lock arms 53 and 54 are swung. , 52 before the load is applied, the load is absorbed by the eccentric cam 61, so that no excessive load is applied to the support shafts 51, 52.

  Further, in the wheel lock device 3 according to this embodiment, two leg portions 51i, 51i, 52i, which hold the support shafts 51, 52 by the biasing force, are provided on the rear end side surface of the frame component member 47. Locking springs 51g and 52g having a U-shape having 52i are attached. Therefore, since the support shafts 51 and 52 are urged from both sides so as to be sandwiched between the two leg portions 51i, 51i, 52i and 52i, the insertion is smooth and firm with respect to the frame constituent member 47. It will be stopped. Further, since the locking springs 51g and 52g are attached not to the frame component member 46 but to the frame component member 47 on the back side, it is installed in a place where it is difficult to remove from the outside, which is preferable in terms of safety.

  Further, in the wheel lock device 3 according to this embodiment, engagement grooves 51d and 52d for engaging the locking springs 51g and 52g are provided on the distal ends of the support shafts 51 and 52, respectively. Is provided over the entire circumference. Accordingly, the leg portions 51i, 51i, 52i, 52i of the locking springs 51g, 52g are fitted into the engaging grooves 51d, 52d by the urging force of the locking springs 51g, 52g, and the support shafts 51, 52 are more strongly fixed. Can be locked.

  In the wheel lock device 3 according to this embodiment, the locking springs 51g and 52g are fitted into the engagement grooves 51d and 52d by the urging force, thereby completing the pushing of the support shafts 51 and 52. It has become. With such a configuration, the pushing-in completion position where the abutting portions 51b and 52b abut against the vertical portion 46b of the frame constituting member 46 is when the spring members 51g and 52g are fitted into the grooves, so that the spring members 51g and 52g are engaged with the engaging grooves 51d and 51d, respectively. There is no danger of jumping out of 52d. Further, when the support shafts 51 and 52 are inserted into the through holes 47h and 47m and the push-in is completed, the support shafts 51 and 52 are positioned.

  Further, in the wheel lock device 3 according to this embodiment, the locking springs 51g and 52g have U-shaped root portions 51h and 52h formed by the side surface portion 46d of the frame component member 46 and the frame component member 47 bottom surface portion 47a. It abuts on the intersecting corners 47v and 47w and is fixed so as to be inclined with respect to both the side face part 46d and the bottom face part 47a. Therefore, the locking springs 51g and 52g are fixed in such a manner that the base portions 51h and 52h abut against the corner portions 47v and 47w, so that the support shafts 51 and 52 are inserted into the through holes 47h and 47m. Even when the retaining springs 51g and 52g are bent and a load is applied to the locking springs 51g and 52g, the locking springs 51g and 52g may be displaced due to the load by the corner portions 47v and 47w receiving the load. Is prevented.

  Further, in the wheel lock device 3 according to this embodiment, the locking springs 51g, 52g are provided with collars and washers 51j, 52j that restrain the movement of the locking springs 51g, 52g in the insertion direction of the support shafts 51, 52. The collar fixed to the frame constituting member 47 by screws 51k and 52k and fixed by screws 51k and 52k is sandwiched between the two legs 51i, 51i, 52i and 52i of the locking springs 51g and 52g. Yes. Therefore, the collar fixed by the screws 51k and 52k receives the leg portions 51i, 51i, 52i, and 52i that are urged in the closing direction of the U-shaped opening, so that the U-shape can be maintained. It becomes. Further, the presence of the washers 51j and 52j can prevent the locking springs 51g and 52g from being displaced in the insertion direction of the support shafts 51 and 52 due to the insertion of the support shafts 51 and 52. Further, the presence of the abutting portions 51b and 52b of the support shafts 51 and 52 can prevent the support shafts 51 and 52 from coming off in the axial direction.

  In the wheel lock device 3 according to this embodiment, the male thread portion 56a of the tool 56 rotates counterclockwise at the rear ends of the support shafts 51 and 52 (the front end side of the wheel lock device 3). Thus, female screw portions 51a and 52a that can be screwed are formed. Therefore, only the administrator of the wheel lock device 3 possessing the special tool 56 inserts the tool 56 into the female screw portions 51a and 52a formed on the support shafts 51 and 52, thereby supporting the support shafts 51 and 52. Can be pulled out from the wheel lock device 3. Therefore, since a general person who does not have the special tool 56 screwed in the counterclockwise direction cannot release the restraint of the wheel 101, illegal escape (just escape) and theft of a bicycle or the like can be prevented.

Further, in the wheel lock device 3 according to this embodiment, the female screw portions 51 a and 52 a are provided in the housing 41 so that the tool 56 is inserted from the outside of the housing 41 surrounding the wheel lock device 3 and can be engaged. It is arrange | positioned in the position facing the notch hole 41h. Therefore, even when the wheel lock device 3 is surrounded by the housing 41 and disposed as a part of the parking system, the support shafts 51 and 52 can be pushed into and pulled out of the wheel lock device 3 from the outside of the housing 41. It becomes.
In addition, since the female screw portions 51a and 52a are located at the back of the housing 41, it is difficult for ordinary people to see and touch, and it is possible to prevent the support shafts 51 and 52 from being pulled out illegally. Further, since the support shafts 51 and 52 can be pulled out from the outside of the housing 41 in this way, the wheel lock device 3 breaks down with the lock arms 53 and 54 restraining the wheel 101, and the wheel 101 is Even when the rails 21 and 31 cannot be removed, the restraint is released by a simple operation of pulling out the support shafts 51 and 52, and the wheel lock device 3 or the failed portion of the device can be taken out from the housing 41.

  In the bicycle parking system according to this embodiment, the bicycle parked in the low rack unit 1 and the high rack unit 2 can be locked and unlocked in accordance with the payment of the parking fee. In addition, the bicycle parking system according to this embodiment can manage the parking of bicycles in the low rack unit 1 and the high rack unit 2.

  In particular, the wheel lock device 3 according to this embodiment includes lock arms 53 and 54 that lock the wheel 101, a motor 62 that rotates the output shaft 62b when energized, an eccentric cam 61 that rotates together with the output shaft 62b, and a lock It has long holes 53d and 54d formed in the arms 53 and 54 and into which the eccentric cam 61 is inserted. Therefore, the wheel lock device 3 according to this embodiment rotates the eccentric cam 61 by the rotation of the output shaft 62b of the motor 62, and the lock arm 53, into which the eccentric cam 61 is inserted by the displacement accompanying the rotation of the eccentric cam 61, 54 can be swung. Therefore, both the lock arms 53 and 54 can be opened and closed by using a simple motor 62 and a simple mechanism that can rotate the output shaft 62b by energization.

  In the wheel lock device 3 according to this embodiment, when the forced escape is attempted, the lock arms 53 and 54 move in the closing direction, so that the forced escape can be prevented. Further, when the forced escape is attempted, the eccentric cam 61 is separated from the lock arms 53 and 54, so that the mechanism that drives the lock arms 53 and 54 can be prevented from being damaged. The motor 62 is a motor that can rotate in both directions. This is for the case where the lock arms 53 and 54 hit the air valve or the like and cannot swing to the end. That is, when the lock arms 53 and 54 are closed, when the lock arms 53 and 54 hit a foreign object such as an air valve or a reflector attached to the spoke, when they hit the wheel 101 placed in a shifted manner, and to the deformed rim. When it hits, the motor 62 rotates to a place where it can go and locks at that position. Thereafter, when the lock arms 53 and 54 are opened, the motor 62 rotates in the reverse direction. By this operation, it becomes possible to cope with a deformed rim or the like. In this way, even if the motor 62 is energized for a predetermined time, even if the closed position detection sensor 65 does not detect it, that is, the lock arms 53 and 54 cannot be fully closed, the other side is not damaged. In addition, an extra load is not applied to the drive source side, and a reliable lock can be obtained.

  In the state where the eccentric cam 61 is in contact with the lock arms 53 and 54 at the upper end of the cylindrical outer peripheral portion and the wheels 101 are locked by the lock arms 53 and 54, as shown in FIGS. The position where the lock arms 53, 54 and the eccentric cam 61 are in contact with the center of rotation of the eccentric cam 61 is located on a substantially straight line. For this reason, when the lock arm 53 and the lock arm 54 are to be opened in a state where the wheels 101 are locked by the lock arms 53 and 54, the force applied to the eccentric cam 61 by the opening force is almost equal to those forces. The force is in the direction from the contact point toward the rotation center of the eccentric cam 61. Therefore, the force applied to the eccentric cam 61 by the force for opening the lock arm 53 and the lock arm 54 hardly generates a component force in the direction in which the eccentric cam 61 is rotated. Moreover, since the lock arms 53 and 54 move in opposite directions, the rotational forces acting on the eccentric cam 61 are also in opposite directions. As a result, in a state where the wheels 101 are locked by the lock arms 53, 54, the eccentric cam 61 is difficult to rotate even if the lock arms 53, 54 are opened, so that the wheels 101 are locked by the lock arms 53, 54. The state can be maintained.

  In addition, the wheel lock device 3 according to this embodiment includes a deceleration unit 63 that decelerates between the output shaft 62b and the eccentric cam 61 so that the rotational speed of the eccentric cam 61 is lower than the rotational speed of the output shaft 62b. Is provided. Therefore, the force for rotating the eccentric cam 61 is increased by the speed reduction unit 63 and acts on the output shaft 62 b of the motor 62. Accordingly, the resistance force of the cogging torque acting between the rotor and the stator becomes extremely large, and even when the motor 62 is not energized, even if force is applied in the direction of opening both the lock arms 53 and 54. Both lock arms 53 and 54 hardly move. For this reason, the force transmitted to the eccentric cam 61 is also reduced, and the eccentric cam 61 is difficult to rotate. As a result, the locked state of the wheel 101 by the lock arm 53 and the lock arm 54 can be maintained while using a small motor 62 having a low output.

  In the wheel lock device 3 according to this embodiment, the lock arm 54 and the lock arm 53 swing in the reverse direction. As a result, it is possible to ensure an opening angle that is approximately twice that of a case where only the lock arm 53 is swung and opened.
