Description

  The present invention relates to a bicycle lock excellent in distinguishability in a situation where visibility is lowered such as at night, and a key used for the bicycle lock.

  Conventionally, bicycle locks for preventing bicycle theft have been widely used. These are attached to bicycle wheels and the like, and there are various forms. For example, there are horseshoe locks, box-type locks, chain locks, and rod-like bodies between the spokes of the wheels. The wheel can be made non-rotatable by passing it through the chain.

On the other hand, in low visibility situations such as at night or in bad weather, a reflective member such as a reflective tape or reflector lens is attached to the bicycle body to make the surrounding vehicle recognize the presence of the bicycle and prevent traffic accidents. Is provided.
Although this reflecting member reflects light from a light source such as a headlight of an automobile, the reflecting member does not sufficiently reflect depending on the positional relationship with the light source, so that the function may not be exhibited.

  In addition, since the reflecting member is always attached to the bicycle, the initial function may be significantly deteriorated due to secular change such as dirt. Further, the reflecting member may be damaged due to mischief or the like.

  Furthermore, a light emitting member incorporating a light emitter such as a light emitting diode may be used as an alternative to the reflecting member as described above. This is because the light emitting member itself shines, and has an advantage that the visibility is stable as compared with the above reflecting member. However, even in this light emitting member, like the above-described reflecting member, it is always attached to a bicycle, and therefore there is still a possibility of function deterioration due to secular change. Further, since it is more expensive than the reflecting member, there is a risk of being stolen when it is always attached to a bicycle.

  In view of this, it is an object of the present invention to provide a bicycle lock and a key used for the bicycle lock that are excellent in visibility, have no risk of functional deterioration due to secular change, and are not subject to theft. .

  In order to solve the above problems, the first device of the present application is a bicycle lock using a key 2 that can be inserted into and removed from the key hole 11 of the lock body 1, and is inserted into the key hole 11 of the keys 2. The light emitter 21 that emits light when supplied with electricity is provided in the portion 2a exposed from the keyhole 11, and the light emitter 21 can emit light at least while the bicycle B is running. A bicycle lock is provided.

  In the second device of the present application, the light-emitting body 21 is a light-emitting diode, and a vibration sensor 23 is provided. The vibration sensor 23 is used for traveling the bicycle B to which the bicycle lock is attached. The light emitting mechanism 2c, which is an electric circuit that can emit light from the light emitting diode 21 by sensing the vibration, is provided. The sensor 23 is incorporated in the light emitting mechanism 2c, and provides the bicycle lock according to claim 1.

  The third device of the present application is a key 2 of a bicycle lock that can be inserted into and removed from the keyhole 11 of the lock body 1, and includes a light emitting diode 21, a power switch 22, a vibration sensor 23, a sensor interlock switch 24, a battery. The light emitting diode 21 is provided in the portion 2a exposed from the key hole 11 when the part 2b of the key 2 is inserted into the key hole 11, and the energizing switch 22 is connected to the power source 25. The electric circuit between the LED 21 and the light-emitting diode 21 is manually opened and closed. The vibration sensor 23 can detect vibration around the key 2, and the sensor interlock switch 24 can detect the vibration sensor 23. Accordingly, the electric circuit between the battery 25 and the light emitting diode 21 is automatically opened and closed, and a part 2b of the key 2 is inserted into the key hole 11 and energized. The bicycle lock is characterized in that when the bicycle B is run with the switch 22 in a conductive state, the electric circuit is turned on by vibration of the running bicycle B, and the light emitting diode 21 emits light. Provide the key to use.

  In the invention described in claim 1 of the present application, a light-emitting body 21 is provided on the key 2, and the light-emitting body 21 can emit light at least while the bicycle B is running. We were able to provide it. In addition, since the key 2 is removed from the lock body 1 at the time of locking, the bicycle lock can be provided with little risk of functional deterioration due to secular change and no risk of theft.

  In addition to the above effect, the device described in claim 2 of the present application is provided with a vibration sensor 23 capable of detecting vibrations caused by the running of the bicycle B, so that light is emitted when there is no vibration such as when the vehicle is stopped. Since the diode 21 is extinguished, a bicycle lock that can minimize the consumption of electricity can be provided.

Further, according to the invention described in claim 3 of the present application, by providing the light emitting diode 21, it is possible to provide a key used for a bicycle lock having excellent visibility. In addition, the provision of the vibration sensor 23 capable of sensing the vibration caused by the traveling of the bicycle B provides a key used for a bicycle lock with minimal power consumption.
In addition, since the mechanism for causing the light emitting diodes 21 to emit light is collectively provided on the key 2 side, it is always removed from the bicycle B at the time of locking, and there is a possibility that an electric circuit may fail due to intrusion of rainwater or the like. Is also small.
Also, by replacing the conventionally used key of the lock body 1 with that of the present invention, it is possible to provide a bicycle lock that is easy and inexpensive and highly safe.

  Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a main part showing the configuration of the bicycle lock of this example. FIG. 2 is an explanatory diagram showing an electric circuit of the light emitting mechanism in the key of this example. 3 and 4 are explanatory views showing an example of the form of the bicycle lock of this example.

  The present invention is a bicycle lock using a key 2 that can be inserted into and removed from the keyhole 11 of the lock body 1. The bicycle lock of this example is attached so as to straddle the wheel of the bicycle B as shown in FIG. 4, and is arranged inside the lock body 1 as shown in FIG. This is a horseshoe lock that can be pulled out and coordinated between spokes (not shown) of the bicycle B.

The horseshoe lock of this example has a keyhole 11, and as shown in FIG. 1, the key 2 is inserted into the keyhole 11 to perform the unlocking operation. Specifically, the state in which the collar piece 12 is pulled out from the lock body 1 is a locked state, and the key 2 can be removed from the keyhole 11 in this locked state. The state in which the key 2 is twisted in a state where the key 2 is inserted into the keyhole 11 and the hook 12 is housed in the lock body 1 is an unlocked state.
Examples of the horseshoe lock include those in which the keyhole 11 is coordinated on the front as shown in FIG. 3 (A), and those in which the keyhole 11 is coordinated on the upper surface as shown in FIG. 3 (B). The present invention can be implemented in various forms.

As shown in FIG. 1, the key 2 of this example is a portion that is provided with a grip portion 2 a that can be pinched with a finger by a user of a horseshoe lock, and a key pile 27 that can be inserted into the keyhole 11. And a certain key pile forming portion 2b.
The grip portion 2a is a portion exposed from the key hole 11 when the key 2 is inserted into the key hole 11, and in this example, a light emitting diode 21 is provided as a light emitter that emits light when supplied with electricity. Yes. In addition, a light-emitting body is not limited to the light emitting diode 21 of this example, A small light bulb and another light emitting element can be used.

  In order to cause the light-emitting diode 21 to emit light to the grip portion 2a of this example, as shown in FIG. 2, the energization switch 22, the vibration sensor 23, the sensor interlocking switch 24, the battery 25 as a power source, and the capacitor C, A resistor R or the like is provided, and the light emitting mechanism 2c is configured by these built-in electric circuits. In addition, as shown in FIG. 1, the electric circuit which comprises the light emission mechanism 2c in this example shall be stored compactly on the printed circuit board.

In this example, as shown in FIG. 1, the light emitting diode 21 is provided at the end of the grip portion 2 a, and when the key mountain forming portion 2 b is arranged in the key hole 11, It is coordinated on the front side so as to be visible.
In the light emitting mechanism 2c of this example, one light emitting diode 21 is provided, but a plurality of light emitting diodes 21 may be provided. When a plurality of light emitting diodes 21 are provided, they may be provided together in one direction with respect to the grip portion 2a, or may be provided so as to face in multiple directions.
In addition, the light emitting diode 21 may be always lit during lighting or may be blinking.

The grip portion 2a is covered with the cover 26. However, the cover 26 may be entirely opaque, and only the light emitting diode 21 may be exposed so as to be visible. Or a part of it may be transparent.
Further, a reflection plate for reflecting or scattering light emitted from the light emitting diode 21 may be provided in the light emitting mechanism 2 c such as around the light emitting diode 21.

The energization switch 22 manually opens and closes an electric circuit between the battery 25 and the light emitting diode 21. In this example, it is a slide switch. When the knob 22a is arranged on one side, it is in a conductive state, and when it is arranged on the other side, it is in a cut-off state.
For example, when it is not desired to cause the light emitting diode 21 to emit light such as when the key 2 is removed from the lock body 1 or during the daytime, the light emitting diode 21 is detected by a vibration sensor 23 described later by turning off the energizing switch 22. Therefore, the battery 25 can be prevented from emitting light, and the life of the battery 25 can be extended.

  Although the energizing switch 22 in this example is a manual switch, for example, it may be a switch that automatically conducts when the key pile forming portion 2b is inserted into the key hole 11 of the lock body. In addition, a sensor that can detect the brightness of the surroundings may be provided in the light emitting mechanism 2c, and a switch that automatically enters when the surroundings become dark according to the detection of the sensor.

The vibration sensor 23 can sense vibration around the key 2. In the light emitting mechanism 2c of the present example, when the energization switch 22 is in a conductive state and the vibration sensor 23 detects vibration, the sensor interlock switch 24 described below is turned on, and the light emitting diode 21 is turned on. Can emit light.
Therefore, when the bicycle B is run with the key mountain forming portion 2b of the key 2 inserted into the key hole 11 of the lock body 1 and the energization switch 22 being conductive, the vibration generated in the running bicycle B is subjected to vibration. Thus, the light emitting diode 21 can emit light.

  The sensor interlock switch 24 automatically opens and closes an electric circuit between the battery 25 and the light emitting diode 21 in response to the detection of the vibration sensor 23. In this example, a transistor is used.

  The battery 25 is a small battery such as a button battery. Here, as described above, the light-emitting diode 21 is turned off by the vibration sensor 23 when there is no vibration such as when the vehicle is stopped. Further, since the light emitting diode 21 is turned off even when the energization switch 22 is in the cut-off state, the consumption of the battery 25 is minimized.

  It should be noted that a power source is not provided on the key 2 side, but a battery or a solar cell is provided on the lock body 1 or a power generation device capable of generating power using the rotational force of the wheels is provided, and the key mountain forming portion 2b is provided. Alternatively, electricity may be supplied to the light emitting mechanism 2c.

  Since the light emitting mechanism 2c is provided on the key 2 side as described above, the key 2 is removed from the lock body 1 when the bicycle is stopped and the horseshoe lock is locked. Is in a state. Therefore, there is no fear of functional deterioration due to secular change caused by being always attached to a bicycle as in the past. In addition, since it is removed from the bicycle every time it is locked, there is little risk of theft or mischief.

  In addition, by forming the same key ridge as the key used conventionally in the key ridge forming portion 2b, the lock body 1 itself is used as it is, and the light emission of the light emitting diode 21 is used as a horseshoe lock. The bicycle lock can be provided easily and inexpensively and with high safety.

  In this example, horseshoe locks have been described, but the implementation of the present invention is not limited to horseshoe locks, and various types of bicycle locks that use keys, such as box locks and chain locks, may be used. The present invention can be applied to the form of In the horseshoe lock as in this example, there is no problem because the key 2 is prevented from being pulled out of the keyhole 11 in the unlocked state, but the keyhole 11 is also in the unlocked state, such as a chain lock. In the bicycle lock in which the key 2 can be removed from the door, it is desirable to provide a means for preventing the key 2 from falling off.

It is explanatory drawing which shows the electric circuit of the light emission mechanism in the key of this example. (A) (B) is explanatory drawing of the perspective which shows an example of the bicycle lock of this example.
