Description

The present invention relates to a bicycle parking device that is installed in a bicycle parking lot and locks a bicycle.

Bicycle parking lots are often equipped with a bicycle parking device that locks two-wheeled vehicles such as bicycles in conjunction with the payment device. As the bicycle parking device, for example, the bicycle parking device disclosed in Patent Documents 1 and 2 is known. According to these patent documents, the restraining means is closed to hold the front wheel of the bicycle located in the parking position. A solenoid is used to lock / unlock the restrained state by the restraining means. By operating the solenoid with electric power, it is possible to electrically control it with a payment device. There are two types of solenoids: a push type that pushes a magnetic material from a coil, a pull type that the coil attracts a magnetic material, and a push-pull type that uses two coils, push and suction. The solenoid used in the bicycle parking device is generally a push-pull type for performing two operations of unlocking / locking.

The solenoid used in the bicycle parking device locks the restraint means when a predetermined time such as 30 minutes elapses and the bicycle parking is confirmed, and unlocks when the bicycle parking fee is settled. To do. When unlocking / locking, power is supplied and driven to perform unlocking or locking operation displacement only temporarily, but during other periods, power is supplied to maintain the unlocking or locking state. There is no. Therefore, if the operating displacement fails when power is supplied, it cannot be automatically corrected thereafter. A factor that causes the motion displacement to fail is when a mechanical force that hinders the motion of the solenoid acts on the restraining means. In particular, in the case of unlocking, there is a great deal of dissatisfaction on the part of the user that the bicycle cannot be taken out even though the payment has been completed. In such cases, it does not occur frequently, so the current situation is that when a problem occurs, it is dealt with on-site.
An object of the present invention is to provide a bicycle parking device capable of reliably unlocking even if a mechanical force that hinders the operation of the solenoid acts on the restraining means.

The bicycle parking device according to the present invention has a bar that fixes a restraining means that makes the bicycle unable to escape, a solenoid that is operated by electric power, and a pin and a link that transmits the movement of the moving magnetic pole of the solenoid to the bar. In a bicycle parking device having a connecting mechanism including
The connecting mechanism connects a link provided with a sliding groove in which the pin can slide along a locus on which the pin should originally move , and connects the pin and the link to form the link in the sliding groove. When the pin has an urging member that urges the position and the pin moves in the sliding groove when the bar is placed in a state where it cannot be moved due to some obstacle, and then the obstacle disappears. The pin is positioned at a normal position by the urging force of the urging member.

According to the present invention, even if the solenoid fails to operate and displace when power is supplied, the lock can be automatically unlocked by the action of the urging member thereafter, so that the settlement is completed. It is possible to solve the situation where the bicycle cannot be taken out even though it is there.

It is a figure which shows the operation state at the time of locking of a bicycle parking device. It is a side sectional view of the bicycle parking device. It is the figure which looked at the conventional bicycle parking device from the bicycle warehousing side. It is a figure which shows the operation state at the time of unlocking of a bicycle parking device. It is a figure which shows the operating state at the time of locking of the bicycle parking device of another form. It is a figure which shows the operating state at the time of locking of the bicycle parking device of another form.

A solenoid is a member for immobilizing a restraining means that is hooked on the spokes, wheels, or part of the vehicle body to prevent the bicycle parked from escaping directly / indirectly (hereinafter referred to as "lock"). ) Is moved to the locking / unlocking position. When the operating displacement of the solenoid fails, even if the moving magnetic pole of the solenoid tries to move while the current is flowing through the solenoid, the moving magnetic pole is held by a larger force and the bar does not move, resulting in that. This is the case when the operating displacement is not performed.

2 and 3 are the bicycle parking device described in Patent Document 1. The bicycle parking device X includes a swing rack 5, restraining means 6, 13 and a solenoid 16. The swing rack 5 supports the wheel w1 of the bicycle between the left and right side surface portions 2a and 2b. The swing rack 5 is pivotally attached via a support shaft 9 bridged between the left and right side surface portions 2a and 2b, and swings when the rolling wheel w1 is placed as shown by the broken line.

The restraining means 6 is a crescent-shaped bar as a whole, and can swing around the fixed support shaft 10. The lower end of the restraint means 6 is in contact with the swing rack 5, is pushed down in response to the movement of the swing rack 5, and swings so that the upper end of the restraint means 6 enters the inside of the side surface portions 2a and 2b. The urging member 8 constantly applies an urging force to the restraining means 6 so as not to enter between the side surface portions 2a and 2b of the restraining means 6. The restraining means 6 prevents the bicycle from directly escaping from the bicycle parking device 1, and when the upper end of the restraining means 6 enters the inside of the side surface portions 2a and 2b, the rolling wheel w1 moves to the bicycle parking device 1. It becomes a state that cannot be separated from 1.

The striker 7a is fixed to the lower surface of the swing rack 5, and the hooking mechanism 7b is fixed to the bottom surface 2c of the bicycle parking device 1. The hooking mechanism 7b has a hook-shaped restraining means 13, and when the striker 7a descends toward the hooking mechanism 7b, the restraining means 13 rotates forward around the support shaft 7c and hooks the striker 7a. .. When the striker 7a separates from the hooking mechanism 7b, it reverses and releases the hooked state. The latch mechanism 7b further has a bar 14, and when the bar 14 is pushed into the hook mechanism 7b, the normal rotation state of the restraining means 13 is fixed (locked), and the bar 14 is pulled out from the hook mechanism 7b. , And it is unlocked. The bar 14 is linked to the moving magnetic pole 15 of the solenoid 16, and the bar 14 can be operated by the solenoid 16. When the swing rack 5 is pushed down (the restraining means 13 hooks the triker 7a), the restraining means 6 that restrains the bicycle to the bicycle parking device 1 cannot be displaced. Therefore, it is the restraint means 6 that makes the bicycle unable to escape directly from the bicycle parking device 1, whereas the restraint means 13 indirectly makes it impossible to escape.

Next, a case where the operating displacement of the solenoid 16 fails will be described. When a force is applied to the restraining means 13 of the hooking mechanism 7b in the vertical direction assumed as the movement of the striker 7a, the bar 14 can be pushed / pulled out without any trouble. However, the restraining means 13 and the bar 14 become inoperable only when a force is applied in the F direction (FIG. 3). The force in the F direction is not originally a force to be applied, but it can occur accidentally and momentarily. Even if the unlocking current temporarily flows (several hundred milliseconds) to the solenoid 16 under the state where the force in the F direction is applied, the solenoid 16 can displace the lock 14 in the unlocked state. It will fail without operation.

FIG. 4 is a bicycle parking device described in Patent Document 2. FIG. 4A shows the unlocked state, and FIG. 4B shows the locked state. Members having the same function as in FIG. 3 are designated by the same quotation marks. The bicycle parking device Y includes a restraining means 13, a bar 14, a solenoid 16a for locking, and a solenoid 16b for unlocking. The major difference from the bicycle parking device X in FIGS. 2 and 3 is that in the bicycle parking device X, the striker 7a of the swing rack 5 was locked by the restraining means 13, but in the bicycle parking device Y, the bicycle was rolled by the restraining means 13. The point is to lock the ring itself. The restraining means 13 can swing around the shaft 11a, and when the restraining means 13 swings, the upper end of the restraining means 13 directly puts the bicycle in a restrained state. The urging member 12 constantly applies an urging force so that the restraining means 13 is in a non-restrained position. When the restraining means 13 swings, the operating point 17c swings via the links 17a and 17b (the link 17b is a lever operation centered on the fulcrum 11b). The link 18 is connected to the solenoid 16a and the solenoid 16b. The bar 14 is pin-coupled to the link 18 by a pin 22 and performs a lever motion around the fixed fulcrum 21. The bar 14 determines whether to pass the operating point 17c or to block it depending on the swing position. In the state of FIG. 4B, the restraining means 13 is trying to move in the unlocking direction by the urging member 12, while the bar 14 is damming at the position of the operating point 17c.

Next, a case where the operating displacement of the solenoid 16b fails will be described. When a force is applied to the restraining means 13 in the F direction (FIG. 4B), the restraining means 13 and the bar 14 become inoperable. The force in the F direction is not originally a force to be applied, but it can occur accidentally and momentarily. The operating point 17c strongly pushes the restraining means 13 by the force in the F direction, and makes the restraining means 13 inoperable by biting or a high static friction force. Therefore, the solenoid 16b cannot displace the lock 14 in the unlocked state, resulting in an operation failure.

Since there are physical restrictions on the mounting directions of the solenoids 16 (FIGS. 2 and 3) and 16b (FIG. 4) and the directions of the latch 14, a connecting mechanism is usually provided. In the present invention, the connecting mechanism for transmitting the motion of the solenoids 16 and 16b to the latch 14 has been improved. The connecting mechanism can be realized by a pin and a link connected by a pin, but in the present invention, in some links, the pin can move in a sliding groove provided in the link, and the pin is concerned. An urging member is provided to move the sword to the normal position where it should be. The sliding groove is provided along the trajectory on which the pin should originally move. Then, even if the bar 14 is placed in a state where it cannot be moved due to some obstacle, the pin moves in the sliding groove, and when the obstacle disappears thereafter, the pin is in the normal position of the sliding groove due to the urging force of the urging member. I am trying to move to.

FIG. 1 is a bicycle parking device 1 according to the first embodiment. Like the bicycle parking device X, the bicycle parking device 1 is a type of bicycle parking device that indirectly makes it impossible for the bicycle to escape by the restraining means 6. FIG. 1A shows a locked state, and FIG. 1C shows an unlocked state. FIG. 1B shows a state in which an unexpected force is applied to the restraining means 13 and the bar 14 becomes difficult to operate. The restraining means 13 rotates around the fulcrum 13c. When the striker 7a abuts on the lower end 13a of the restraint means 13, the striker 7a covers the upper end 13b of the restraint means 13, and when the striker 7a is pulled up, the lower end 13a of the restraint means 13 rises and the striker 7a It is in a state of waiting for contact.

In FIG. 1A, the coupling mechanism 19 includes a link 19b, a pin 19d, and a sliding groove 19g. The coupling mechanism 19 further includes a link 19a, a pin 19c, and a pin 19e. When the solenoid 16b on the unlocking side pulls in the moving magnetic pole 15, the link 19a connected by the pin 19c interlocks with the moving magnetic pole 15 and makes a lever motion around the fixed support shaft 10. The link 19b connected to the link 19a by the pin 19d is moved slightly upward to the left in the drawing. The link 19b is provided with a sliding groove 19g on which the pin 19d can slide, and the sliding groove 19g is a groove along a movement locus on which the pin 19d should originally move. The urging member 20 connects the pin 19d and the link 19b, and the pin 19d is always attracted to the regular position R (the right end of the sliding groove 19g) in the sliding groove 19g. The link 19b is pin-coupled to the bar 14 by the pin 19e.

In FIG. 1C, when the solenoid 16 pulls up the moving magnetic pole 15 in order to unlock the lock 14, the link 19a attempts to move the pin 19d toward the upper left of the drawing. Under the normal state, the pin 19d is housed in the normal position R in the sliding groove 19g by the urging member 20, and the link 19b moves in the upper left direction exclusively by the urging force of the urging member 20. The urging member 20 has an urging force sufficient to resist the force required to unlock the lock 14 in the normal state.

Next, in FIG. 1B, an unexpected force is applied to the restraining means 13, and the bar 14 becomes inoperable. The pin 19d moves the sliding groove 19g to the left. This is because, as a result of pulling up the moving magnetic pole 15 in order for the solenoid 16 to unlock the lock 14, only the pin 19d moves to the original position via the link 19a. The position of the pin 19d in the sliding groove 19g in this state is referred to as a shunting position S. The urging member 20 cannot resist the moving force of the solenoid 16 and is stretched (the urging force of the urging member 20 is smaller than the moving force of the solenoid 16).

The unexpected force applied to the restraining means 13 is instantaneous and eventually disappears. At this time, the bar 14 becomes movable, the urging force of the urging member 20 acts, and the action of attracting the pin 19d to the normal position R in the sliding groove 19g occurs. Since the sliding groove 19g is provided along the movement locus of the pin 19d, the link 19b later moves following the movement locus of the pin 19d by the action of the urging force of the urging member 20, and the solenoid 16 It performs the unlocking operation that should have been performed during operation.

FIG. 5 is a bicycle parking device 100 according to the second embodiment. Like the bicycle parking device Y, the bicycle parking device 100 is a type of bicycle parking device that directly locks the rolling wheels of the bicycle by the restraining means 13. FIG. 5A shows a locked state, FIG. 5C shows an unlocked state, and FIG. 5B shows a state in which an unexpected force is applied to the restraining means 13 and the bar 14 becomes difficult to operate.

In FIG. 5A, the coupling mechanism 119 includes a link 119b, a pin 119d and a sliding groove 119g. The pin 119d is pin-coupled to the bar 14, and the bar 14 performs a lever motion around the fixed fulcrum 21. When the link 119b is moved in the direction of the solenoid 16b on the unlocking side, the link 119b is provided with a sliding groove 119g along the movement locus in which the pin 119d moves. The pin 119b slides in the sliding groove 119g. The urging member 120 connects the pin 119d and the link 119a, and always attracts the pin 119d to the normal position R (the end of the sliding groove 119g on the solenoid 16b side) in the sliding groove 19g.

In FIG. 5C, when the solenoid 16b pulls in the moving magnetic pole 115 in order to unlock the bar 14, the link 119b attempts to move the pin 119d toward the solenoid 16b. Under the normal state, the pin 119d is accommodated in the normal position R in the sliding groove 119g by the urging member 120, and the link 119b moves in the solenoid 16b direction exclusively by the urging force of the urging member 120. The urging member 120 has an urging force sufficient to resist the force required to unlock the lock 14 in the normal state.

Next, in FIG. 5B, an unexpected force is applied to the restraining means 13, and the bar 14 becomes inoperable. The operating point 17c strongly pushes the restraining means 13 by the force in the F direction, and makes the restraining means 13 inoperable by biting or a high static friction force. The sliding groove 119g moves in the solenoid 16b direction while leaving the pin 119d in the locked position. This is because, as a result of pulling in the moving magnetic pole 115 in order for the solenoid 16b to unlock the bar 14, only the sliding groove 119 g of the link 19a has moved to the original position. The position of the pin 119d in the sliding groove 119g in this state is also referred to as the shunting position S as in the first embodiment. The urging member 120 cannot resist the moving force of the solenoid 16b and is stretched (the urging force of the urging member 120 is smaller than the moving force of the solenoid 16b).

The unexpected force on the restraining means 13 is momentary and eventually disappears. At this time, the bar 14 becomes movable, the urging force of the urging member 120 acts, and the action of attracting the pin 119d to the normal position R in the sliding groove 119g occurs. Since the sliding groove 119g is provided along the movement locus of the pin 119d, the link 119b later moves following the movement locus of the pin 119d when the urging force of the urging member 120 is applied, and the solenoid. The unlocking operation that should have been performed at the time of the operation of 16b is performed.

The link 19a of the first embodiment performs a lever motion around the fixed support shaft 10, but in the bicycle parking device 200 of the present embodiment, the linear motion of the solenoid 16 is performed in a straight line instead of the link 19a of the lever motion. The difference is that a link 219a that transmits as motion is provided. The same components as those in the first embodiment are designated by the same reference numerals. In FIG. 6A, the coupling mechanism 219 includes a link 219b, a pin 219d, and a sliding groove 219g. In FIG. 6C, when the solenoid 16 pulls up the moving magnetic pole 15 in order to unlock the lock 14, the link 19a attempts to move the pin 19d toward the upper left of the drawing. Under the normal state, the pin 219d is housed in the normal position R in the sliding groove 219g by the urging member 220, and the link 219b moves in the upper left direction exclusively by the urging force of the urging member 220.

In FIG. 6B, an unexpected force is applied to the restraining means 13, and the bar 14 becomes inoperable. The pin 219d moves the sliding groove 219g to the left side (shelter position S). This is because, as a result of pulling up the moving magnetic pole 15 in order for the solenoid 16 to unlock the bar 14, only the pin 219d has moved to the original position via the link 219a.

The unexpected force applied to the restraining means 13 is instantaneous and eventually disappears. At this time, the bar 14 becomes movable, the urging force of the urging member 220 acts, and the action of attracting the pin 219d to the normal position R in the sliding groove 219g occurs. Since the sliding groove 219g is provided along the movement locus of the pin 219d, the link 219b later moves following the movement locus of the pin 219d by the action of the urging force of the urging member 220, and the solenoid 16 Performs the unlocking operation that should have been performed during operation.
The bin 219e connecting the bar 14 and the link 219d slides on the sliding groove 219h provided on the link 219d, which is used exclusively when the solenoid 16 performs the locking operation. It is a thing. That is, when the solenoid 16 moves in the locking direction when the locking is energized, the locking is completed even if the restraining means 13 is in a halfway state.
