Description

  The present invention relates to a bicycle parking machine and a bicycle parking system. More specifically, the present invention relates to a bicycle parking machine and a bicycle parking system improved to prevent unauthorized departure of bicycles.

  As a bicycle parking machine where the locking mechanism does not break or break down even if it acts in the direction that the arm is opened in an attempt to unload the bicycle in the locked state, the two arms lock the wheel by pinching the wheels from both sides Was used (see Patent Document 1). In addition, there is a structure that simplifies the structure, and one arm protrudes from one side, and the bicycle wheel is sandwiched between the arm and the wheel base to lock.

FIG. 11 shows an example of a conventional bicycle parking machine 1 ′ that sandwiches a wheel from one side. The bicycle wheel 7 is sandwiched between the tip 5B ′ of the arm 5 ′ and the wheel base 2 so that the bicycle wheel 7 does not come off the bicycle parking machine 1 ′.
However, if the wheel 7 is deliberately pulled out due to unauthorized removal such as theft or mischief, the tip 5B ′ of the arm 5 ′ is loaded upward and rearward, and the arm 5 ′ is distorted or damaged. Thus, there is a problem that the bicycle wheel 7 can come off even in the locked state. That is, the rim 7A of the wheel 7 slides linearly on the lower side of the tip 5B ′ of the arm 5 ′, and a load is continuously applied to the tip 5B ′, so that the arm 5 ′ may be distorted or damaged. The load is also transmitted to the frame 3 via the moving shaft 5G, and there is a problem that the frame 3 may be distorted or broken.

JP 2006-347249 A

  An object of this invention is to provide the bicycle-parking machine which prevents the distortion and breakage of the apparatus with respect to unauthorized delivery.

For example, as shown in FIG. 4, the bicycle parking machine 1 according to the first aspect of the present invention includes a wheel base 2 on which a bicycle wheel 7 is placed and a frame on which the wheel base 2 is mounted in order to park the bicycle. 3. A frame 3 that supports the wheel base 2 so as to move downward by the weight of the bicycle, and is rotatably supported by the frame 3, and rotates as the wheel base 2 moves downward. The front end portion 5B protrudes between the spokes of the wheel 7, and includes an arm 5 that holds the bicycle in the parking position, and an arm lock mechanism 6 that locks the arm 5 that the front end portion 5B protrudes between the spokes. The arm 5 is formed of a steel material having a yield point stress of 500 N / mm ² or more, and has a protrusion 5H that contacts the rim 7A at one point when the wheel 7 is held downward.

Here, “supported” of “supported by the frame 3” and “supported by the frame 3” is supported by being indirectly attached in addition to being supported by being directly attached to the frame 3. Cases are also included. For example, the wheel base 2 may be supported by being attached to and supported by the frame 3 via the rotation shaft 2A on one end side, and attached to and supported by the frame 3 to be slidable in the vertical direction on the other end side. Further, the arm 5 may be supported by being attached to an intermediate plate 5C attached to the frame 3 so as to be rotatable via a rotation shaft 5G. In addition, the “tip portion” of the arm 5 here corresponds to the second tip portion 5B in each embodiment.
“Contact at one point” typically means that there is one protrusion 5H and contact at one vertex. However, the present invention is not limited to this, and even when the projection 5H has a plurality of branches, the apex (contact part) of these branches is a narrow part of the tip part (second tip part 5B) of the arm 5, for example, the second tip part. It suffices if it exists in the range of the length d ₀ (for example, within 5 mm) of the lower side of 5B. “Protrusions” refer to protrusions viewed from the side, and may or may not have protrusions in the thickness direction. That is, it exists apex of the protrusion 5H viewed from the side is concentrated within a length d ₀ in the longitudinal direction of the second tip portion 5B lower. The apex of the protrusion 5H is preferably rounded and smoothly formed so as not to damage the rim 7A.

The material of the arm 5 is typically carbon tool steel (particularly SK85). Due to the high yield point stress, plastic deformation (permanent deformation) can be suppressed. For this reason, even if a lateral external force acts on the second distal end portion 5B of the arm 5 and bending occurs, if the external force is removed, it returns to its original shape due to elasticity. Even if an upward force is applied to the second tip portion 5B of the arm 5, since a carbon tool steel material having a high yield point stress is used, the protrusion 5H portion and the second tip portion 5B are hardly deformed. . The yield point stress is preferably 500 N / mm ² or more.

When configured as in this mode, the arm is made of steel with a high yield point stress, and when the wheel is held down, it has a protrusion that contacts the rim at one point, preventing distortion and breakage of the device against unauthorized removal. A bicycle parking machine can be provided. Further, since the yield point stress of the arm material is 500 N / mm ² or more, even if bending occurs, it returns to its original shape elastically if the external force is removed.

In the first aspect, the bicycle parking machine according to the second aspect of the present invention is fixedly supported by the frame 3 as shown in, for example, FIG. A rack 4 for suppressing movement is provided.
Here, the rack 4 is typically made of a pipe material, and is provided at the left and right of the parking position so that the bicycle does not fall down in the lateral direction and to suppress the lateral movement. In addition, the left and right racks are connected in front of the parking position to prevent the bicycle from moving forward.
If comprised like this aspect, the fall of the bicycle to the horizontal direction can be prevented.

In the second aspect, the bicycle parking machine according to the third aspect of the invention is fixed to the frame 3 and reinforces the periphery of the binding portion 3A of the frame 3 with the rack 4 as shown in FIG. A member 9 is provided.
Here, the periphery of the binding portion 3A with the rack 4 is an area surrounding at least 360 ° around the binding portion 3A. When a load is applied to the rack 4, a force acts on a wide area of the frame 3, so that the reinforcing range may extend over the entire arm 5 mounting side of the frame 3. The reinforcement can be performed, for example, by bringing the reinforcement member 9 into contact with the frame 3 and fixing with a screw.
If comprised like this aspect, even if stress is applied to the frame, it is reinforced by the reinforcing member, so that the frame is difficult to deform.

In the bicycle parking machine according to the fourth aspect of the present invention, in any of the first to third aspects, for example, as shown in FIG. 3, the arm 5 is a plate-like body having a thickness of 3 to 5 mm. Composed.
Here, when an unexpected external force is applied, the arm 5 may be bent if the plate thickness is thin, and conversely, if it is thick, the frame 3 side may be deformed (destroyed). For this reason, it should be set to an appropriate plate thickness. The plate thickness of the arm 5 is, for example, 3 to 5 mm when using a material having a high yield point stress (500 N / mm ² or more), and 4 mm in the embodiment. It was.
If comprised like this aspect, since an arm is set to appropriate thickness, an arm and a frame are hard to change.

A bicycle parking system 10 according to a fifth aspect of the present invention includes a plurality of the bicycle parking machines 1 according to any one of the first to fourth aspects, and a control device 14 that remotely controls whether the arm 5 is allowed to rotate. Prepare.
Here, the bicycle parking system 10 includes a plurality of bicycles that are placed side by side in the same direction (one that is placed at the same height, and one that the front wheels are alternately placed at a high position and a low position. ) However, they may be placed alternately in opposite directions.
If comprised like this aspect, a bicycle parking system can be comprised using the bicycle parking machine which prevents the distortion and damage of the apparatus with respect to an unauthorized delivery.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.

A first embodiment will be described with reference to FIGS.
The state where the wheel 7 (refer FIG. 4) is not mounted is shown in the front view of the bicycle parking machine 1 of FIG. The bicycle parking machine 1 includes a wheel base 2, a frame 3, a rack 4, an arm 5, an intermediate plate 5C, a tension spring 5D, and an arm lock mechanism 6 (including a lock pin 6D, see FIG. 2).
The wheel base 2 is a part on which the bicycle wheel 7 (typically the front wheel) is placed on the bottom of the tray, and has a rotating shaft 2A (fulcrum) on the introduction side, and rotates around the fulcrum. A roller 2B is provided. When the wheel 7 is placed on the bottom of the tray over the roller 2B, the bicycle load acts on the wheel base 2, and the wheel base 2 rotates around the fulcrum 2A, and the opposite side of the fulcrum 2A is It is lowered and held at a predetermined parking position. The predetermined parking position is typically a position where the wheel base 2 is held horizontally.

The frame 3 is also referred to as a base, and is a board to which each component of the bicycle parking machine 1 is attached. In this embodiment, a sheet metal of 2t (sheet thickness 2 mm) is employed. The frame 3 is provided on the left and right and lower sides of the wheel base 2, and the left and right portions are connected on the lower side, and the area on the side on which the arm 5 is mounted is wider than the opposite side.
In the rack 4, two pipe members are fixed to the frame 3 in parallel with each other while maintaining a predetermined interval. This prevents lateral movement and rollover of the bicycle wheel 7 while parked. In addition, the two pipe members are connected at the front side to prevent the bicycle from moving forward. The predetermined interval is a distance somewhat wider than the width of the bicycle wheel 7.

The arm 5 is a component that sandwiches the wheel 7 in the locked state. In this embodiment, the wheel 7 is sandwiched between the wheel base 2 and the second tip 5B of the arm 5. Further, when an unexpected external force is applied, the arm 5 may be bent if the plate thickness is thin. Conversely, if the arm 5 is thick, the frame 3 may be deformed (distorted or broken). Therefore, it is important to set the plate thickness of the arm 5 in an appropriate range. For example, 3 to 5 mm is appropriate for a material having a high yield point stress. In the present embodiment, the arm 5 is made of carbon tool steel and has a thickness of 4 t (4 mm). Even if the second tip portion 5B of the arm 5 is deformed by an external force (typically applied upward and backward with respect to the parking position in the bicycle parking machine 1), the carbon tool steel material has an external force. It is preferable that the yield point stress is 500 N / mm ² or more so that it returns to the original state when it is removed. The arm 5 is attached to the intermediate plate 5C via the rotation shaft 5G, and the intermediate plate 5C is fixedly attached to the frame 3 in the vertical direction. Reference numeral 5D denotes a tension spring (first urging spring), which is installed at an appropriate position between the substantially intermediate hole of the arm 5 and the intermediate plate 5C, and urges the arm 5 to maintain the open position. Reference numeral 6D denotes a lock pin that locks the arm 5 in the closed position in the closed state. Details of the arm 5 will be described later.

  The state where the wheel 7 is not mounted is shown in the side view of the bicycle parking machine 1 in FIG. However, regarding the wheel base 2, a state where the wheel 7 is not placed is indicated by a two-dot chain line, and a state where the wheel 7 is placed is indicated by a dotted line. As described above, when the wheel 7 is placed on the wheel base 2, the wheel base 2 rotates around the fulcrum 2 </ b> A and the opposite side of the fulcrum 2 </ b> A descends and is held at a predetermined parking position. Refer to the description of FIG. 1 for the frame 3, the rack 4, the arm 5, the intermediate plate 5C, and the tension spring 5D.

  The bicycle parking machine 1 includes an arm lock mechanism 6. The arm lock mechanism 6 restrains the rotational movement of the arm 5 so that the arm 5 in the closed position is not in the open position, and includes a driving means 6A, an intermediate plate 6B, a second urging spring 6C, a lock It has a pin 6D, a link mechanism 6E, and a detector 6F. The drive means 6A electrically restrains the arm to the closed position and releases it to the open position. Specifically, for example, the restriction to the closed position and the release to the open position are performed by one solenoid. The intermediate plate 6B is typically a substrate that is fixedly and parallelly attached to the frame 3 with a certain distance (for example, about 1 mm), and the driving means 6A, the lock pin 6D, and the detector 6F are attached to the intermediate plate 6B. It is attached. Further, a through hole through which the lock pin 6D protrudes is provided. The lock pin 6D is a pin that mechanically restrains the arm 5 in the closed position by projecting from the through hole of the intermediate plate 6B in conjunction with the driving means 6A. In the open state, the second urging spring 6 </ b> C urges the lock pin 6 </ b> D in a direction in which the lock pin 6 </ b> D is pulled out from the through hole, for example, by a compression spring. The link mechanism 6E is a motion transmission mechanism configured to link the lock pin 6D with the driving means 6A and operate in conjunction with the driving means 6A. The detector 6F electrically detects that the position of the first tip 5A of the arm 5 is at a predetermined position, and thereby detects that the bicycle wheel is at a predetermined parking position. Further, the driving of the driving means 6A is electrically detected. The detected detection signal is output to the control device 14. The intermediate plate 5C and the intermediate plate 6B are orthogonal to each other in the vicinity of the frame 3, but are integrally connected at an orthogonal position. In addition, 3A is a binding part with the rack of a flame | frame. The intermediate plate 6B also has a function of preventing water from the upper part from reaching the electrical components.

  FIG. 3 is a perspective view of the arm 5. Here, points other than those described mainly with reference to FIG. 1 will be described. The arm 5 has a first tip portion 5A and a second tip portion 5B, and a hole 5E and a shaft hole 5F are formed. In addition, a protrusion 5H is formed on the lower side of the second tip 5B (on the first tip 5A side). The first tip portion 5A comes into contact with the bottom of the wheel base 2 and rotates around the rotation shaft 5G attached to the intermediate plate 5C in conjunction with the vertical movement of the wheel base 2. Yes. The second distal end portion 5B of the arm 5 is located in a state in which the bicycle slightly protrudes from the frame 3 onto the wheel platform 2 (hereinafter referred to as an open position) when the bicycle is not in the parking position (see FIG. 1). The bicycle can be moved on the wheel base. The second tip 5B protrudes from the frame 3 by the pivoting movement of the arm 5 due to the descent of the wheel base 2 in a state where the bicycle is in the parking position, and further protrudes from the spoke gap of the bicycle wheel 7, It is located in the state (henceforth a closed position) which sandwiches wheel 7 with wheel stand 2. In this state, when the bicycle is lifted, the rim 7A of the wheel 7 hits the second tip 5B (actually hits the protrusion 5H below the tip of the second tip 5B), and the bicycle cannot be released. The arm 5 is thus rotated around the rotation shaft 5G so as to be able to go back and forth between the open position and the closed position. In the closed position, there is a gap between the second tip 5B and the wheel 7. The first tip portion 5A and the second tip portion 5B are different in size and shape.

  In the present embodiment, when the arm 5 is in the open position, the tip of the second tip 5B slightly protrudes from the side wall of the frame 3. Further, in the closed position, the second distal end portion 5 </ b> B greatly protrudes from the side wall of the frame 3 and is in a position to sandwich the wheel 7 together with the wheel base 2. When the wheel 7 is forcibly pulled out in this state, the rim 7A of the wheel 7 makes point contact with the protrusion 5H. Thus, the arm 5 has a shape that allows the second tip 5B to protrude and retract onto the wheel base 2 by rotating around the rotation shaft 5G. With this shape, when the operation of forcibly pulling out the wheel 7 is performed, the rim 7A of the wheel 7 makes point contact with the protrusion 5H formed on the lower end of the second tip 5B of the arm 5. , It will hit the rim 7A. Anyone trying to pull out the bicycle will catch on the protrusion when trying to lift the wheel 7. For this reason, it is often the case that the raising and lowering is repeated rather than continuously lifting, and the contact with the protrusion 5H becomes intermittent, and therefore the load on the protrusion 5H is often intermittent. That is, the rim 7A slides linearly on the lower side of the second tip 5B of the arm 5, and a load is continuously applied to the second tip 5B, so that the arm 5 is prevented from being distorted.

The tip of the protrusion 5H is preferably formed smoothly so as not to damage the rim 7A. Further, “contact at one point” typically means that there is one protrusion 5H and contact at one vertex. However, the present invention is not limited to this, and even when the projection 5H has a plurality of branches, the apex (contact portion) of these branches is a narrow portion below the tip of the second tip 5B of the arm 5, for example, the second tip. It suffices if it exists in the range of the length d ₀ (for example, within 5 mm) of the lower side of 5B. “Protrusions” refer to protrusions viewed from the side, and may or may not have protrusions in the thickness direction. Further, by adopting a carbon tool steel material having a high yield point stress for the arm 5, even when deformation occurs, the arm 5 returns to its original state when the external force is removed. In this way, the arm 5 does not undergo plastic deformation (permanent deformation), and even if it is deformed, it returns to its original state due to elasticity, so it is extremely difficult for the wheel 7 to come off. In addition, when the load is intermittently applied, the accumulated load amount is smaller than that when the load is continuously applied, so that it is difficult to deviate from this point. Further, when an unexpected external force is applied, the arm 5 may be bent if the plate thickness is thin, and conversely, if it is thick, the frame 3 side may be deformed (destroyed). For this reason, it should be an appropriate plate thickness. Therefore, the thickness of the arm 5 is set to a range of 3 to 5 mm, specifically 4 mm. The hole 5E is a hole in which the tension spring 5D is fixed with a screw. The shaft hole 5F is a shaft hole through which the rotation shaft 5G passes.

  The state in which the wheel 7 is mounted is shown in the front view of the bicycle parking machine 1 in FIG. When the wheel 7 is placed on the bottom of the wheel base 2, the load of the bicycle acts on the wheel base 2, the wheel base 2 rotates around the fulcrum 2A, and the opposite side of the fulcrum 2A descends. 2 is held at a predetermined parking position. That is, the wheel base 2 is held horizontally. Further, the arm 5 rotates around the rotation shaft 5G, the second tip 5B protrudes from the frame 3, and further protrudes from between the spokes of the wheel 7, and the protruding second tip 5B is the wheel. It reaches the closed position where the wheel 7 is sandwiched together with the base 2. Then, the arm lock mechanism 6 is actuated so that the lock pin 6D protrudes from the shoulder portion of the arm 5 and prevents the arm 6 from rotating backward. In the closed position, there is a slight gap (several tens of millimeters for a general 26/27 inch tire) between the second tip 5B of the arm 5 and the rim 7A of the wheel 7. This is because the arm 5 can be rotated around the rotation shaft 5G by providing a margin for lifting upward when taking out the bicycle. Further, this is to be able to cope with various dimensions of the wheels 7. When the arm 5 rotates and the second tip 5B of the arm 5 comes out of the retracted spoke, the bicycle can be taken out.

  The front view of the bicycle parking machine 1 in FIG. 5 shows a state where the wheel 7 is forcibly pulled out. Since the wheel base 2 is not mounted with the wheel 7, it is in the raised position as in FIG. 1, but since the arm 5 is locked by the lock pin 6D, it is held in the closed position. Since a protrusion 5H that contacts the rim 7A at one point is provided on the lower side of the second tip 5B of the arm 5, when the wheel is pulled out in this state, the rim 7A of the wheel 7 is intermittently moved. Point contact with the protrusion 5H. That is, the projection 5H hits the rim 7A. As a result, it is possible to avoid the rim 7A from sliding on the second tip 5B of the arm 5 in a linear manner and continuously applying a load to the second tip 5B and causing the arm 5 to be distorted. . Further, by adopting a carbon tool steel material having a high yield point stress for the arm 5, even if the deformation occurs, it is elastically deformed and returns to its original state when the external force is removed. For this reason, it is very difficult to pull out the wheel 7.

  FIG. 6 shows a state in which the outer cover 8 is attached to the frame 3. The outer cover 8 covers the arm lock mechanism 6 to prevent rain and mischief. Specifically, those made of hard resin are used. Stainless steel, galvanized steel plate, and other metal / alloy plates may be used.

  FIG. 7 shows a bicycle parking system 10. The bicycle parking machine includes a bicycle parking machine 1 </ b> A, a bicycle parking machine 1, and a bicycle parking machine 1 that includes a rail 12 that guides the bicycle to the bicycle parking machine 1. The bicycle parking system 10 in this embodiment is a combination of a bicycle parking machine 1A and a column 13 connecting the base 11 and the bicycle parking machine 1B with a bicycle parking machine 1B on a pedestal 11 provided on the ground surface of the bicycle parking lot (a bicycle front wheel). Can be held at a high position) and alternately controlled by the control device 14. The control device 14 performs control such as receiving a signal indicating that the arm 5 is locked from the bicycle parking machines 1A and 1B, and transmitting an unlocking signal to the bicycle parking 1A and 1B.

FIG. 8 shows a processing flowchart of bicycle locking (set) / unlocking (reset) in the present embodiment.
(Standby state)
In the standby state where the bicycle is not put in the bicycle parking machine 1, the arm 5 of the bicycle parking machine 1 is opened by the action of the tension spring 5D (the second tip 5B of the arm 5 is slightly on the wheel base 2 from the frame 3). The position that protrudes to the position is maintained. For example, the wheel base 2 is temporarily pushed by an external force when leaving without permission, and the arm 5 is in a closed position (a position where the second tip 5B of the arm protrudes from the frame 3 and sandwiches the wheel 7 together with the wheel base 2). However, since the arm 5 is biased in the direction to the open position by the tension spring 5D, the arm 5 returns to the open position as soon as the external force disappears.

[Locking treatment]
When the bicycle parking machine 1 is vacant (when the bicycle can be parked), the arm 5 maintains the open position, so that a person who intends to park can visually recognize the bicycle parking machine 1 that can park the bicycle and smoothly. The bicycle can be guided to the bicycle parking machine 1. A person who intends to park the vehicle guides the wheel 7 (typically the front wheel) of the bicycle (possibly on a rail) to the wheel base 2.
When viewed from the side, the wheel base 2 has the introduction side as a fulcrum 2A, and a roller 2B is provided around the fulcrum 2A. When the wheel 7 rides on the roller 2B, the load of the bicycle acts on the wheel base 2 and is guided to a predetermined parking position and placed on the wheel base 2 (S101). When the bicycle is placed on the wheel base 2, the opposite side of the fulcrum of the wheel base 2 is lowered (S102), and the first tip portion 5A of the arm 5 is pushed downward. Along with this, the arm 5 rotates around the rotation shaft 5G (clockwise in FIG. 1), the second tip 5B protrudes between the spokes of the wheel 7, and the arm is in the closed position ( S103). At this time, the tension spring 5D extends. The detector 6F detects that the arm 5 is in the closed position (S104), and transmits a closed position detection signal to the control device 14.

The control device 14 that has received the closed position detection signal from the detector 6F starts time measurement, and determines whether or not the closed position of the arm 5 has been maintained for a predetermined time. The controller 14 resets the time measurement if the detector 6F detects the open position of the arm 5 before the predetermined time elapses, and drives if the closed position of the arm 5 is maintained for a predetermined time. A locking signal is transmitted to the means 6A. The predetermined time is, for example, a time for preventing the arm 5 from being locked immediately even when the arm 5 is closed, and can be set to an appropriate value, for example, 10 seconds.
The driving means 6A that has received the locking signal from the control device 14 drives the lock pin 6D to protrude by the solenoid (S106). The lock pin 6D protruding by the drive of the drive means 6A restrains the pivoting operation of the arm 5 to the open position and enters a locked state (S107). The control device 14 waits for a command to release the arm 5 (that is, a command to release the lock pin 6D).

[Unlocking process]
In the unlocking process, for example, when a predetermined fee is paid from a person who tries to take out the bicycle, the control device 14 transmits an unlocking signal for releasing the lock state to the driving means 6A (S201). Be started. The drive means 6A of the arm lock mechanism 6 receives the unlocking signal from the control device 14 (S202), and drives the solenoid to release the protrusion of the lock pin 6D (S203). By releasing the protrusion of the lock pin 6D (S204), the restraint of the arm 5 whose restraint operation is restrained by the lock pin 6D is also released. A person who wants to take out the bicycle parks the bicycle upward from the wheel platform 2 of the bicycle parking machine so that the arm 5 whose restraint is released is rotated around the rotation shaft 5G (counterclockwise in FIG. 4). By lifting, the arm 5 moves to the open position (S205). As the arm 5 is rotated by the biasing force of the tension spring 5D, the wheel base 2 is also raised. Thereby, a bicycle can be taken out from the bicycle parking machine 1 (S206), and the bicycle parking machine 1 enters a state of waiting for parking.

[Forcibly pulling out the bicycle]
In a state where the arm 5 is locked, the second tip 5B of the arm 5 is in a position protruding from the side surface of the frame 3 on one side. Usually, there is a gap between the rim 7A of the bicycle wheel 7 and the second tip 5B of the arm 5. In this state, when the bicycle is forcibly pulled out, the arm 5 rotates by the gap, but when the shoulder of the arm 5 abuts against the lock pin 6D, the arm 5 rotates further. Is blocked. If the bicycle is further pulled out while the lock pin 6D is in contact with the arm 5, a force is applied to the second tip 5B of the arm 5 in the direction of pulling out the bicycle (rear) and the direction of lifting the arm 5 itself upward. .

  In the case of the arm 5 ′ having the conventional shape, the contact of the wheel 7 with the rim 7A is substantially linear contact, so that the lower side of the second tip 5B ′ of the arm 5 ′ functions as a guide, and the rim 7A is on the lower side. Then, a continuous force is applied to the arm 5 ′ itself to promote the deformation of the arm 5 ′ (see FIG. 11). It was also found that deformation due to the load accumulates only by increasing the strength of the arm 5 'material. On the other hand, in this embodiment, since the protrusion (contact portion) 5H formed on the lower side of the second tip 5B has a point contact shape, the rim 7A of the wheel 7 hits the protrusion 5H. The lower side of the second tip 5B does not act as a guide (see FIG. 5). No matter how hard you pull out, it will be point contact and will not act as a guide. Although the load on the arm 5 is large at the time of point contact, by adopting carbon tool steel with high yield point stress, there is temporary deformation but plastic deformation is small, and external force is removed even if deformation occurs When it is done, it will return to elasticity. Therefore, the cumulative deformation of the arm 5 itself can be reduced, and it is extremely difficult to pull out the wheel 7.

  A second embodiment will be described with reference to FIG. FIG. 9 shows a state in which the reinforcing member 9 is attached to the frame. The reinforcing member 9 is a plate-like body that reinforces the binding portion 3 </ b> A of the frame 3 with the rack 4 in order to suppress bending of the frame 3. Specifically, for example, a material similar to that of the arm 5, for example, a carbon tool steel with a high yield point stress (thickness 4 t) is employed.

  When the bicycle is forcibly pulled out, a part of the striking force related to the protrusion 5H of the second tip 5B of the arm 5 is received by the arm 5. The strength of the arm 5 is improved by changing the material, and a part of the striking force is absorbed by the arm 5. However, the frame 3 receives a force (particularly a backward force) that is not absorbed by the arm 5. If the force applied to the frame 3 is large, the frame 3 may be distorted or damaged. As a countermeasure, in this embodiment, the periphery of the binding portion 3A of the frame 3 on the attachment side of the arm 5 with the rack 4 is reinforced by the reinforcing member 9. The periphery of the binding portion 3A is at least 360 ° surrounding the binding portion 3A. When a force is applied to the rack 4, the force acts on a wide area of the frame 3, so the reinforcing range may be an appropriate range in which the reinforcing member 9 surrounding the binding portion of the frame 3 can be easily attached. It is good over. Further, by adopting a carbon tool steel material (thickness 4t) having a high yield point stress similar to that of the arm, the reinforcing member 9 can suppress plastic deformation to be small, and can prevent distortion and breakage.

  Embodiment 3 will be described with reference to FIG. Example 3 relates to a modification of the protrusion 5H. FIG. 10 shows an example of the deformation 5H of the protrusion at the second tip 5B of the arm 5. FIG. 10 (a) is a diagram for explaining the requirements for the shape of the protrusion 5H. FIG. 10C is a perspective view showing an example corresponding to the protrusion 5H contacting at one point, and FIG.

Please refer to FIG. The apex (contact part) A of the protrusion 5H is as close as possible to the end surface of the second tip 5B so as to be easily caught by the wheel 7 (for example, the distance d = from the apex of the projection 5H to the end surface of the second tip 5B). 0 to 5 mm). The length B of the end surface is set large (for example, 10 to 30 mm) to ensure the strength of the second tip 5B. The slope angle C of the protrusion with respect to the lower side (side on the first end side) of the second tip portion 5B is set large (for example, 30 to 60 degrees) so as to be easily caught on the wheel 7. The inclination angle D of the end surface with respect to the surface perpendicular to the lower side of the second tip 5B is an angle at which the arm 5 is in the open position and the end surface slightly protrudes from the rack 4 (the end surface is parallel to the longitudinal direction of the rack 4 in the open position). Preferably, the angle varies depending on the vertical and horizontal dimensions of the arm 5, for example, 25 to 35 degrees. Further, “contact at one point” typically means that there is one protrusion 5H and contact at one vertex. However, the present invention is not limited to this, and even when the projection 5H has a plurality of branches, the apexes of the projection 5H are narrow portions of the second tip 5B of the arm 5, for example, the length d ₀ of the lower side of the second tip 5B (for example, It suffices if it exists within a range of 5 mm or less. “Protrusions” refer to protrusions viewed from the side, and may or may not have protrusions in the thickness direction. Therefore, it is only necessary that the protrusion is within the length d ₀ in the longitudinal direction of the lower side of the second tip portion 5B (regardless of the presence or absence of branching) while satisfying the above condition. Further, there may be a thickness in the plate thickness direction. (B) is a semicircular protrusion, which has a protrusion in the longitudinal direction of the second tip 5B, but has a uniform shape in the thickness direction. Since it is a semicircular protrusion and has one vertex, it corresponds to a protrusion that contacts at one point. (C) is a hemispherical projection (the diameter in the longitudinal direction may be long), but this case also corresponds to a projection that contacts at one point because there is only one vertex of the projection. (D) are not applicable since the distance d between the apex of the projection with two projections get hit the rim 7A is away d ₀ or more. If, d is applicable if it is d ₀ less. In (b) to (d), B ′ is used as the length corresponding to B in (a). FIGS. 10B and 10C do not move in the longitudinal direction (become a guide) when contacting the rim 7 </ b> A of the wheel 7, so that the wheel 7 does not leave the arm 5. In addition, it is preferable that the lower side of the second distal end portion 5B (side facing the rim 7A) is finished smoothly including the protrusions 5H so as not to damage the rim 7A.

  Example 4 relates to a modification of the arm shape. The arm 5 can rotate around the rotation axis 5G of the arm 5 and has a protrusion that contacts the second tip 5B at one point. The arm 5 is in the open position and the second tip 5B is slightly from the frame 3. And the second tip 5B protrudes between the spokes in the closed position, so that it is possible to prevent the wheel 7 from being pulled out. For example, even if the arm 5 is C-shaped or U-shaped, the above condition may be satisfied.

  In the above embodiment, the case where one arm (single) is provided for each bicycle parking apparatus has been described, but two arms 5 may be provided, for example. However, if it is single, the structure of the wheel lock mechanism is not complicated, and if it is configured as in the embodiment described above, even if it is single, the wheel can be securely locked, and unauthorized delivery is performed. It is possible to prevent the device from being distorted or damaged.

Although the embodiment of the present invention has been described above, the embodiment is not limited to the above example, and it is obvious that various modifications can be made without departing from the spirit of the present invention.
For example, in the bicycle parking system according to the above-described embodiment, a case where there are a plurality of bicycle parking machines has been described. In addition, the bicycle parking system is not limited to the case where the front wheel positions shown in FIG. 10 are alternately arranged between the high and low positions, and even if the front wheels are all at the same height, the direction of the bicycle is alternated. It may be replaced, or the bicycle parking machine may move in the vertical direction or slide in the horizontal direction. Moreover, although the locking device showed the example which restrains a front wheel with an arm and an arm lock mechanism, it may restrain a rear wheel. In the above embodiment, the example in which the end surface of the second distal end portion of the arm slightly protrudes from the frame in the open state has been described. However, the end surface of the arm may be positioned just before the protrusion. Also, the wheel base does not have to be provided with a roller, and the example of detecting the vertical movement of the wheel base when the front wheel side moves up and down and the arm is in the closed position is shown. May move up and down uniformly. Further, although the example in which the frame is installed so that the area on one side on which the bicycle arm is mounted is increased has been described, it may be installed on both sides so that the area on the opposite side is the same or the area on the opposite side is increased. Further, the frame may be a frame shape instead of a plate shape as long as an arm, an arm lock mechanism, and a wheel base are attached. In addition, the dimensions and shapes of the rack, frame, arm, and wheel base can be selected as appropriate, and the arm lock mechanism can also be selected as appropriate. Further, in the above embodiment, an example in which the entire arm is made of the same material has been described. However, a material having a high yield point stress may be used in a place where the force acts strongly, and the arm may be composed of a plurality of materials.

  The present invention is used for bicycle parking machines and bicycle parking system.
