Description

  The present invention relates to a bicycle parking device such as a motorcycle, and can be easily moved in and out, and can be parked without taking up space even in a small site, and with an attached non-power switch. The present invention relates to a front wheel support device that can be easily checked for entry and exit and effective for theft prevention, and a bicycle parking device including the front wheel support device.

  In recent years, the use of motorcycles and motorbikes has increased dramatically as a foot for commuting, attending school or shopping, but there are parking facilities for parking motorcycles, etc. around these stations and shopping streets. Because there are very few, illegal parking has become a social problem because it hinders the running of vehicles and walking of people. This is also because the rent of a place where people can easily gather is very expensive, and there is a problem that a bicycle parking lot such as a motorcycle stand cannot be profitable. For this reason, in order to efficiently park as many motorcycles as possible in a narrow space, there are an increasing number of examples in which the facility is a multi-level parking facility with upper and lower stages.

  On the other hand, there are many accidents in which motorcycles are stolen during parking, and theft of expensive motorcycles is particularly noticeable.

  In general, when a motorcycle is parked, the wheel is locked with its own chain lock, etc., or is locked using a lock device of a bicycle parking lot. In such a conventional lock device, a strong chain is used. Since it is easily broken with tools such as a cutter, there is no way for motorcycle owners to do anything.

In addition, in a conventional parking lot, a motorcycle-specific device for aligning a motorcycle without overturning has not been developed so much. For example, as shown in Patent Document 1 or the like, the tire width of a motorcycle There is known a front wheel support device having a structure in which a pair of struts and restricting members having a slightly wider interval are erected at predetermined intervals, and a continuous cross beam is bridged on each restricting member. In such a front wheel support device, the front wheels are inserted between the pair of regulating members and the motorcycle is erected by the attached stand so that the bicycle is parked and aligned within a specified position or a specified range. is there.

The rear lower part holding body 18 is pivotally supported with respect to the connecting frame part 16 so as to be rotatable about the axis.

  The front-wheel front-end holding body 17 is formed in a substantially V shape by a plane portion 17A and holding piece portions 17B and 17B extending in the expanding direction from both sides of the plane portion 17A. In addition, a portion slightly below the bending point formed in the square shape of the plane portion 17A is firmly fixed to a substantially central portion of the front end frame portion 12 by means such as welding.

By forming the front wheel front-end holding body 17 in a substantially V shape in this way, it can be adapted to all front wheel widths from bicycles and small motorcycles to large motorcycles. It is possible to prevent damage.
Furthermore, by setting the fixing point with the front end frame portion 12 slightly below the bending point formed in the square shape of the plane portion 17A, the lock device 19 housed in the front wheel support device 10 and described later is used. The motorcycle B that is locked and parked is configured not to be forcibly lifted. Of course, in order to make it harder to lift, the upper part of the front wheel holding member 17 may be formed longer.

  On the other hand, the front wheel rear lower portion holding body 18 is basically configured in the same manner as the front wheel front portion holding body 17 and extends from the flat surface portion 18A and both sides of the flat surface portion 18A in the expanding direction. The planar shape of the holding piece portions 18B and 18B is formed in a substantially V shape, and the length dimension of the guide portion side 18C and the connecting portion side 18D in which the cross-sectional shape is formed in a substantially square shape is the guide portion. The side 18C is formed longer. The pipe-shaped shaft portion 18E that is pivotally supported by the central portion of the connecting frame portion 16 is firmly fixed to the flat portion 18A on the connecting portion side 18D by means such as welding.

  By forming the front wheel rear lower portion holding body 18 in a substantially V shape in this way, it can be adapted to all front wheel widths from bicycles and small motorcycles to large motorcycles. Can be prevented from being damaged.

  In this embodiment, the length dimension of the guide part side 18C and the connecting part side 18D of the front wheel rear lower part holding body 18 having a substantially square cross-sectional shape is set so that the guide part side 18C is Since the front wheel support device 10 is in an empty state, the front wheel support device 10 is tilted so that the guide portion side is substantially flush with the guide rail portion 11 due to the weight of the guide portion side, and the front wheel support device 10 of the front wheel at the time of warehousing. It is configured so that it can be smoothly introduced.

Further, lock arms 17C and 18F are extended from the front wheel front holding body 17 and the rear lower rear part holding body 18, and the front wheels of the motorcycle B are received in the lock arms 17C and 18F. In some cases, the free end portion is configured to overlap, and the overlapped portion is formed with a hole portion into which the lock 19 (see FIG. 2) can be engaged. In this embodiment, a charge clearing device J that is linked to the lock / unlock state of the lock 19 is disposed on the lock arm 18F, and the charge clearing device J operates when the lock 19 is locked. The lock 19 is unlocked when it is settled. Since the lock 19 and the fee clearing machine J can be of a known configuration, a detailed description of the configuration is omitted here.
In addition, one end portion of the guide rail portion 11 is connected to the central portion of the connection frame portion 16 and the cross-sectional shape extending outward from the rear end portion of the base member 2 is substantially concave. As shown in FIG. 2, the terminal end portion 11A of the guide rail portion 11 disposed between the platform portions 4 and 4 is bent toward the floor surface or the ground G side, and the guide rail portion 11 of the wheel at the time of loading and unloading. It is configured so that entry and exit operations can be performed smoothly. Of course, the width dimension of the guide rail portion 11 is configured such that the front and rear wheels of the large motorcycle B can smoothly enter and house.

  Further, the flat surface portion 17A of the front wheel front holding member 17 is of a non-powered system that operates by releasing the pressing force when the front wheel enters the front wheel support device 10 and the pressing force with the front wheel when leaving the front wheel. A security device 20 is attached.

  Here, although the structural example of this crime prevention apparatus 20 is shown in FIG. 11, the crime prevention apparatus 20 of this invention is not limited to the arrangement | positioning and shape which were illustrated.

  First, the piezoelectric ceramic elements 211 and 212 are accommodated in a case 40, and the case 40 is mounted on the front wheel front holding member by an appropriate means (adhesive, double-sided tape, screwing, welding, etc.) not shown. 17 is attached to the back surface side of the flat surface portion 17A, and is configured to detect fluctuations acting on the front wheel front-holding body 17 and perform communication using electric power generated by the piezoelectric ceramic elements 211 and 212. Yes.

  The piezoelectric ceramic elements 211 and 212 are connected to the housing 23 housing the piezoelectric ceramic body 21 and the steel ball 22, the base 41 for supporting the housing 23, and the elastic housing 23 and the base 41. And an elastic member 42 made of a leaf spring or the like that swings the housing 23 so that the steel ball 22 repeatedly collides with the piezoelectric ceramic body 21. In addition to the above-described leaf spring, the elastic member 42 is made of a rubber material (silicon rubber, gel material, thermoreversible elastomer, etc.), a foam material, or a low Young's modulus Ti alloy (a Ti alloy having a large elastic deformation). It may be used.

  That is, in this embodiment, as shown in FIG. 12, the piezoelectric ceramic bodies 21 are arranged on both ends of the housing 23 whose both ends are closed, and the piezoelectric ceramic bodies 21 are generated by striking the steel balls 22. .

  A cushion material 25 is bonded to one side surface of the housing 23 using an adhesive 24, and the piezoelectric ceramic body 21 is bonded only to the central portion of the cushion material 25 using the adhesive 24. Similarly, the piezoelectric ceramic body 21 is bonded to the other side surface of the housing 23 so as to face each other.

  A protector plate 27 is fixed to the center of the opposing surfaces of the two piezoelectric ceramic bodies 21. A guide passage 28 is disposed between the piezoelectric ceramic bodies 21, and a rollable steel ball 22 is provided in the guide passage 28. Further, the housing 23 is provided with a circuit unit 30 (see FIG. 13) including the transmitting unit 32. The housing 23 swings due to vibrations when the front wheels are moved in, and also swings even when the front wheels are moved out to generate electric power.

  In the present invention, when the piezoelectric ceramic body 21 is horizontally disposed, for example, not only the central portion but also both end portions thereof are held by the cushion material 25, or Both end portions may be held by the cushion material 25, and the support portions may be arranged and held on the upper and lower surfaces of the piezoelectric ceramic body 21.

  The piezoelectric ceramic body 21 has two plate-like piezoelectric ceramic elements 211 and 212 having the same form (same material, same shape and same thickness), and the polarization polarities of the ceramic elements 211 and 212 are set in the same direction. In addition, an ultrathin metal electrode (not shown) made of a conductive metal such as phosphor bronze or brass and having a thickness of 10 μm to 50 μm is disposed between the piezoelectric ceramic elements 211 and 212, and these piezoelectric ceramic elements 211, 212 and a metal electrode are joined.

  By making the metal electrode extremely thin in this way, the mechanical resistance due to the metal electrode can be suppressed very slightly, and the joint surface between the two ceramic elements 211 and 212 and the metal electrode is centered (does not expand or contract). Even if a flexural vibration occurs in the part), the damping of the flexural vibration by the metal electrode can be suppressed as small as possible. In the configuration of this embodiment, when the ceramic element 211 on one side expands, the ceramic element 212 on the other side contracts, and the electrodes of the output voltage are in opposite directions, so that both piezoelectric ceramic elements 211 and 212 are in parallel. The power generation configuration is connected to.

  Further, in this embodiment, when the flexural vibration is performed, the piezoelectric ceramic element 211 (or 212) performs both expansion and contraction, and the polarization is not canceled out efficiently. Power generation is performed. A current as electric energy generated by the ceramic element 211 is taken out from the lead wires 261 and 264, and a current as electric energy generated by the ceramic element 212 is taken out from the lead wires 262 and 263. The current generated by 211 and 212 is connected to a lead wire (not shown) conductively connected to the metal electrode so that an alternating current is obtained.

  The cushion material 25 used in the present invention is made of a synthetic resin material, a rubber material, or a soft material in which these are made into a sponge shape. The reason why the cushioning material 25 is used and the piezoelectric ceramic body 21 is fixed to the central part or both ends of the cushioning material 25 by using the adhesive 24 is that the vibration of the piezoelectric ceramic body 21 is not attenuated. It is. When the piezoelectric ceramic body 21 vibrates, the member that supports the piezoelectric ceramic body 21 becomes a factor that attenuates the vibration of the piezoelectric ceramic body 21. In order to remove this damping factor, the piezoelectric ceramic body is used as much as possible by using the cushion material 25. 21 is left free.

  The distortion of the piezoelectric ceramic body 21 configured as described above is a natural vibration of the piezoelectric ceramic itself and continues for a while. In order to continue this natural vibration for a long time, it is important not to transmit this natural vibration to a structure other than the piezoelectric ceramic body 21. Although the natural vibration of the piezoelectric ceramic body 21 is converted as electric energy, all the vibrations of the other structures become mechanical resistances and absorb the natural vibration energy and cannot be taken out as electric energy. For this reason, in this embodiment, by using the cushion material 25 as a means for realizing a soft contact between the piezoelectric ceramic body 21 and another structure so that the natural vibration is not transmitted, The natural vibration of the body 21 can be continued for a long time, and the power generation efficiency is improved. Of course, the cushion material 25 also has a function of reducing the impact applied to the piezoelectric ceramic body 21. The protector plate 27 is made of metal or synthetic resin, and protects the piezoelectric ceramic body 21 from hitting of the steel balls 22.

  In addition, the structure using two steel balls shown in Unexamined-Japanese-Patent No. 2001-145375, the structure which suspends a steel ball with a spring material, etc. are applicable to the electric power generation method by a piezoelectric system. In addition, by applying a configuration in which a single-layer or multi-layer piezoelectric ceramic plate is bonded to a metal plate whose thickness is adjusted to balance the amount of strain deformation, and a steel ball 22 is collided from the metal plate side to generate power. Also good. In FIG. 11, reference numeral BM denotes a front wheel of the motorcycle, and Q denotes a cushion material attached to the case 40.

  Next, the communication is performed by a transmitting unit 32 that transmits a loading / unloading signal as shown in FIG. 13 by using the power generated in the piezoelectric ceramic elements 211 and 212 due to pressure fluctuation during loading / unloading. The signal transmitted from the security device 20 is a signal propagating in the air. In this embodiment, a radio signal (radio wave signal) is used, but an ultrasonic signal, an optical signal, an infrared signal, a sound wave signal, or the like can also be used. .

  As shown in FIG. 13, the receiving device 50 that receives the communication can be installed integrally with or at a distance from the security device 20, and places power in the receiving device 50 where it is difficult for an intruder to find it. It is desirable to install it in any place such as a place where it can be easily supplied and a place where it can be easily managed. In the present embodiment, a single receiving device 50 can receive signals from one or a plurality of security devices 20. When signals are received from a plurality of security devices 20, each signal includes an identification alarm, and it is possible to determine which parking device 1 is arranged to transmit a signal. Has been.

  And when the said receiving device 50 detects unauthorized leaving, this is notified by sound (siren etc.), a voice (intimidation voice) or light etc. around the neighborhood, or the owner of the motorcycle It is configured to automatically notify the pager or mobile phone of the unauthorized delivery status, or to automatically transmit it to the police or the contract security company via the network 53.

The network 53 includes various communication means such as a public line (including mobile communication) and a dedicated line, and may be notified by the Internet or electronic mail in addition to the notification by telephone. Of course, it can also be configured such that an authorized manager of a bicycle parking lot or a motorcycle owner can control the operation of the alarm or the like by a remote control operation. Operation may be performed by making a call to the receiving device 50 (or by e-mail).
In the crime prevention device 20, a signal is transmitted from the transmission unit 32 at the time of entering and leaving. Therefore, since a signal is also transmitted when the manager of the bicycle parking lot or the rightful owner (user) of the motorcycle enters and leaves the vehicle, whether or not to activate an alarm or the like on the receiving device 50 side is controlled. Therefore, it is configured so that only unauthorized entry / exit can be detected.

  By the way, in the crime prevention apparatus 20 configured as described above, the outputs of the piezoelectric ceramic elements 211 and 212 are taken out to the circuit unit 30. As shown in FIG. 13, the circuit unit 30 includes a charging unit 31 that rectifies and charges AC power generated by the piezoelectric ceramic elements 211 and 212 and the above-described transmission unit 32. The signal transmitted from the transmitting unit 32 is received by the receiving unit 51 of the receiving device 50, and the alarm unit 52 provides a second alarm in advance through the network 53 along with notification to the surroundings by sound and light. Notify the set outside. Whether or not an alarm is issued by the alarm unit 52 is controlled from the outside. In addition, the display unit 54 displays which of the parking devices 1 the security device 20 of the plurality of installed security devices 20 has received the signal (blinking of the lamp, lighting of the red lamp, etc.).

  The charging unit 31 of the circuit unit 30 includes a rectifying unit 311, a charging unit 312, a determining unit 313, and a discharge switch unit 314. The rectifying unit 311 is a unit that rectifies the AC power output from the piezoelectric ceramic elements 211 and 212 to generate a pulsating flow. The charging unit 312 is a unit that charges the pulsating flow obtained by the rectifying unit 311 as a direct current. The determination means 313 is a means for intermittently monitoring and determining the amount of charge of the charging means 312 according to the power generation timing of the piezoelectric ceramic body 21. With this means, a very small amount of charge is consumed at the time of monitoring, but since monitoring is performed intermittently, power consumption by monitoring is suppressed and the influence on the charge amount is reduced. When the determination unit 313 determines that the charging amount of the charging unit 312 has reached a level at which transmission is possible, the discharge switch unit 314 starts discharging the charging unit 312 and supplies power to the transmission unit 32 at the subsequent stage. It is means to do.

  Next, the transmission unit 32 includes a communication control unit 321, a signal switch unit 322, a signal generation unit 323, and a discharge stop unit 324.

  The communication control unit 321 is a unit that performs an operation necessary for communication, and this unit is started when power is supplied from the charging unit 231. This means works to turn on the signal switch means 322 when the operation is started, and passes data for transmission to the signal generation means 323. The signal switch unit 322 is a unit that is turned on by the communication control unit 321 and supplies power to the signal generation unit 323. The signal generating unit 323 converts the data for transmission received from the communication control unit 321 into a signal and transmits the signal. The discharge stop unit 324 is a unit that operates the discharge switch unit 314 so as to stop the supply of power from the charging unit 231. This means is operated by the communication control means 321 when the communication control means 321 has passed all the data necessary for transmission to the signal generation means 323.

  14 and 15 are continuous circuit diagrams, which are connected by S point, + point, and-point. The rectifier 311 forms a full-wave rectifier circuit with diodes D1 to D6, and rectifies the AC power output from the piezoelectric ceramic elements 211 and 212 and outputs it as a pulsating current to the subsequent stage. Of the four lead wires 261 to 264 taken out from the piezoelectric ceramic elements 211 and 212, the lead wires 262 and 263 are connected, and the three lead wires are connected to the six diodes D1 to D6. Here, a circuit is formed in which the lead wires 262 and 263 are connected to reduce the number of diodes, but the lead wires 262 and 263 are not connected but connected to eight diodes for full-wave rectification. A circuit may be formed.

  The charging unit 312 includes a capacitor C1. The capacitor C1 may be replaced with a rechargeable battery. The pulsating flow rectified by the rectifying means 311 is sequentially charged as a direct current to the capacitor C1, and the voltage across the capacitor C1 increases every time the steel ball 22 collides with the piezoelectric ceramic body 21 and repeats power generation.

  As the discharge switch means 314, a self-holding type current switch is used. In this embodiment, complementary transistors are used, and the PNP transistor Tr1 and the NPN transistor Tr2 are combined. In this discharge switch means 314, when a voltage approximately 0.6V (a value determined by Tr1) lower than the voltage at point c is applied to point b, Tr1 is turned on and Tr2 is turned on almost simultaneously.

  Thus, when the discharge switch means 314 is turned on, the impedance between the points c and d becomes extremely low. Then, the electric power stored in the capacitor C1 of the charging unit 312 is discharged and supplied to the communication control unit 321 with very little loss. This ON state continues until it becomes a self-holding state and stops discharging.

  The determination unit 313 includes capacitors C2 and C3 and resistors R1 and R2. The capacitor C3 is provided for preventing malfunction. The capacitor C2 and the resistor R1 are provided between the point a shown in FIG. 14 that is the output from the piezoelectric ceramic body 21 and the point b shown in FIG. 15 of the discharge switch means 314. The time constant determines the time for applying the voltage at point b when determining the charge amount. AC power is generated every time the steel ball 22 collides with the piezoelectric ceramic body 211 at the point a. This voltage is a value obtained by adding the voltage in the upper ridge direction of the diode D6 to the voltage at both ends of the capacitor C1. Then, the voltage of the capacitor C1 increases due to charging, and the AC voltage at point a also increases. That is, at point a, an AC voltage substantially proportional to the DC voltage at both ends of the capacitor C1 is obtained every time the steel ball 22 collides, that is, intermittently. The AC voltage at the point a is applied to the point for only a very short period determined by the time constant of the resistor R1 and the capacitor C2. The voltage at the point b is determined by the distribution ratio of the resistors R1 and R2. As described above, when the voltage at the point exceeds the value of about 0.6V lower than the voltage at the point c, the discharge switch means 324 is turned on. . Here, since the voltage at the point b is expressed by (the voltage at the point c × 1−R2 / (R1 + R2)), the voltage at the point b is about 0.6 V lower than the voltage at the point c (the voltage at the point c). When the voltage becomes equal to approximately 0.6 V), the threshold value for the determination is used, and the level of the charge amount is determined based on the threshold value, so that the charge amount for starting discharge can be transmitted by adjusting R1 and R2. This level is arbitrarily set according to the signal to be transmitted, although three points are provided on the lead wire 264 side here, but the lead wire 261 side and the connected lead wire 262 are provided. Further, here, the piezoelectric ceramic elements 211 and 212 are configured so that the determination is made at each timing when one of the two piezoelectric elements 211 generates electric power. Generate electricity The and go judgment at the time, or every n times of timing piezoelectric ceramic body 211 generates power (n is an arbitrary number) may be configured to perform the determination.

  The communication control means 321 includes a communication control circuit 3211, a capacitor C7, a resistor R8, and FET1. The capacitor C7 is provided for stable operation. The resistor R8 and the FET1 are provided for level conversion for interfacing the communication control circuit 3211 and the signal switch means 322 with low power consumption. When power is supplied to the communication control circuit 3211 by discharging from the charging unit 231, a procedure necessary for transmission is executed inside the communication control circuit 3211. Note that the communication control circuit 3211 has low power consumption.

  The signal switch means 323 includes a PNP transistor Tr4, resistors R6 and R7, and a capacitor C6. Since the signal generation circuit 3231 requires a relatively large amount of power, the signal switch means 323 is configured to supply power to the signal generation circuit 3231 using the high-power transistor switch Tr4. The signal switch means 323 operates so that the signal generation means 323 can start the transmission when a command to start transmission from the communication control circuit 3211 passes through the FET 1 and turns on the transistor Tr4 through the resistor R7.

  The signal generation means 323 includes a signal generation circuit 3231 and an antenna 3232. When power is supplied from the signal switch means 323, the signal for transmission received from the communication control circuit 3211 is converted into a radio signal and converted to an antenna. Call from 3232.

  The discharge stop means 324 includes a PNP transistor Tr3, resistors R4 and R5, and capacitors C4 and C5. Capacitors C4 and C5 are provided for preventing malfunction. In this means, when the communication control circuit 3211 finishes sending data necessary for transmission to the signal generation circuit 3231, the communication control circuit 3211 outputs a signal for turning on the transistor Tr3 through the resistor R4. When the transistor Tr3 is turned on, the self-holding of the discharge switch means 324 is released, the discharge of the power stored in the capacitor C7 is stopped, and the transmission operation ends.

  Operation | movement of the crime prevention apparatus 20 of this form example comprised in this way is demonstrated.

  Since the security device 20 does not require wiring of a power line, it can be easily attached even in a place far from an outlet or a place where wiring is difficult. The signal transmitted from the security device 20 attached to the plurality of bicycle parking devices 1 includes an identification alarm for identifying each of them, and a single receiving device 50 receives a plurality of signals. Believe, identify and detect. Further, when the display unit 54 of the receiving device 50 receives a signal from the crime prevention device 20, for example, a lamp corresponding to the description of the bicycle parking device NO1 or the like is turned on so that the illegally parked bicycle parking device 1 is immediately known. Is set to When a legitimate manager or a motorcycle user leaves the vehicle, the receiving device 50 can be alerted by a remote control operation, whether the vehicle is leaving or a signal from the security device 20 of the bicycle parking device 1 is received. Is set not to run. Of course, in this case, it is assumed that the liquidation is completed.

  When the front wheel is received and abuts against the front wheel front holding member 17, the vibration is applied to the security device 20, and the housing 23 swings due to the elasticity of the elastic member 42 attached to the case 40 of the security device 20. Due to this swinging, the steel ball 22 collides with the piezoelectric ceramic body 21 to generate electric power. Further, the steel ball 22 reciprocally rolls due to the elasticity of the elastic member 42, repeatedly collides with the piezoelectric ceramic body 21, and continuously generates power.

  The generated power is input from the piezoelectric ceramic elements 211 and 212 to the circuit unit 30. In the circuit unit 30, every time the piezoelectric ceramic body 21 generates power, an AC voltage is extracted from the output, and this is used for the determination unit 313 to determine the charge amount. Such intermittent monitoring and determination of the charge amount is efficiently determined at the timing when the charge amount increases. In addition, consumption of useless power for determination is greatly suppressed, so that power necessary for transmission can be quickly charged and supplied to the transmission unit 32. As a result, a signal is transmitted from the transmission unit 32 every time the storage / reception is performed.

  The signal transmitted from the transmission unit 32 is received by the reception unit 51 of the reception device 50, and alarm processing is executed by the alarm unit 52. This alarm process threatens the illegal issuer with sound, light, or voice, or notifies the surrounding people of this illegal state, and prompts the withdrawal of the illegal issuer. In addition, the telephone notification by the network 53 promptly notifies the motorcycle owner's pager or alarm device of the occurrence of unauthorized leaving, and notifies the bicycle parking lot manager of the situation.

Moreover, since there is no electric power wiring and it is small, it is hard to notice at a glance and can improve security. In addition, even if it is installed in all possible locations in preparation for unauthorized shippers who do not know when it will be executed, the security device 20 does not cost electricity during standby or during operation, so the economic burden is greatly increased.
