Abstract
Description
Technical Field
[0001] The present invention relates to a wire lock device for fixing two-wheeled vehicles such as motorcycles and bicycles to prevent theft, and a two-wheeled vehicle fixing tool utilizing the wire lock device.
Background Art
[0002] Patent Document 1 discloses a wire lock device with an alarm device that emits a warning sound and an alarm radio wave as one terminal of a home security system when the wire of the wire lock device is forcibly cut. Patent Document 2 discloses a wire lock for use in a security system that performs wireless remote monitoring. Patent Document 3 discloses a wire lock characterized by incorporating an alarm device. However, the implementation of the technologies disclosed in Patent Document 1 and Patent Document 2 requires the construction of a large-scale system. In the technology disclosed in Patent Document 3, if the wire is cut and discarded far away, it is possible to easily steal two-wheeled vehicles such as bicycles. In addition, in order to fix two-wheeled vehicles such as bicycles, it is necessary to attach a wire lock to the parts of the two-wheeled vehicle such as a bicycle, but such a fixing tool for a two-wheeled vehicle such as a bicycle has not been disclosed.

Summary of the Invention
Problems to be Solved by the Invention
[0004] To provide a wire lock device that can be produced at low cost, easily attached to bicycles and other two-wheeled vehicles, and equipped with a wire breakage alarm to prevent theft of bicycles and other two-wheeled vehicles. Also, to provide a fixing device for bicycles and other two-wheeled vehicles that efficiently utilizes the wire lock device. [Means for solving the problem]
[0005] The present invention provides a wire locking device that has a conductor along the wire and continuously sends a signal via an electrical circuit, and when the wire is broken, the signal is interrupted and a warning sound is generated.
[0006] The aforementioned wire locking device is designed to be easily attached to the front or rear suspension of a two-wheeled vehicle such as a bicycle. [Effects of the Invention]
[0007] A wire lock device is provided that can prevent theft by emitting a warning sound when the wire is cut, and is easy to manufacture. Furthermore, a fixing device for two-wheeled vehicles such as bicycles that efficiently utilizes this wire lock device is also provided. [Brief explanation of the drawing]
[0008] [Figure 1] Figure 1 shows the wire portion of the wire lock device with a wire breakage alarm function, as devised, in a retracted state. [Figure 2] Figure 2 shows the wire portion of the devised wire locking device pulled out, wrapped around a fixed support post (a fixed structure such as a guardrail or fence), and inserted into the receiving port that forms the loop of the circuit. [Figure 3] Figure 3 shows the wire lock device of the invention attached to the front suspension of a two-wheeled vehicle such as a bicycle, with the wire portion pulled out and connected to a loop device installed separately on a wall or the like. [Modes for carrying out the invention]
[0009] Wire locks are known for securing bicycles and other two-wheeled vehicles. However, if the wire is cut, there is a risk that the bicycle or other two-wheeled vehicle will be stolen. To address such situations, we provide a wire locking device that can quickly detect when a wire has been cut and deter intruders.
[0010] Therefore, a conductive material is incorporated into the wire. The wire with the conductive material is connected to a warning device that incorporates a power supply, so that power is supplied when the wire is connected and not supplied when it is not. The presence or absence of power can be used to confirm the wire connection. The power status is checked, and if there is no power, the warning device is activated. The warning device can emit a warning sound and can also transmit it to a sub-unit (e.g., a smartphone). The infringer may realize that the infringement has been detected by the warning sound and cease the infringement.
[0011] The warning device may transmit warning information to a sub-unit without emitting a warning sound. It can maintain a record of the infringement without the infringer noticing. It may also notify the police or other authorities if multiple infringements occur. This can deter repeat offenders.
[0012] Furthermore, the wire lock device may be equipped with a lock to secure it. Anyone authorized to unlock the wire lock device can unlock it and deactivate the power. This ensures that only authorized individuals are permitted to deactivate the power. Multiple people can manage the wire lock device.
[0013] The devised wire lock device houses a wire incorporating a power supply, warning device, and conductor in a box-shaped container. This wire is then attached to the front or rear suspension of a two-wheeled vehicle such as a bicycle by passing a U-bolt or similar device through it from the tire side, and securing it with a nut or screw. The design ensures that the nut or screw used for attachment cannot be accessed without unlocking the wire lock device.
[0014] The wire part of the wire lock device of the invention can also be pulled out and inserted into a separately installed loop device for use. In this case, the loop device is provided with a circuit for looping the conductor inside the wire. The loop device is attached to a structure such as a concrete wall using concrete screws or anchor bolts, etc.
Embodiment
[0015] As shown in FIG. 1, the wire lock device of the invention houses a wire incorporating a power source, a warning device, and a conductor in a box-shaped container, and is equipped with a key. The conductor in the wire incorporating the conductor is double-layered, and one end of the wire is fixed to the container incorporating the power source and the warning device. A weak current flows through one of the double-layered conductors, and by inserting the other end of the wire into the receptacle that loops the circuit provided in the container, it is connected to the other conductor, and when current flows, the circuit is completed.
[0016] As shown in FIG. 2, the method of using the wire lock of the invention is to pull out the wire part of the wire lock attached to the front suspension of a two-wheeled vehicle such as a bicycle, wind it around a fixed support column (a structure that cannot be moved such as a guardrail or a fence), and insert it into the receptacle that loops the circuit provided in the container. Here, when the wire is cut, the warning device operates and emits a warning sound to suppress the intruder.
[0017] Also, as shown in FIG. 3, the wire lock device of the invention can be attached to the front suspension of a two-wheeled vehicle such as a bicycle, the wire can be pulled out, and it can be inserted into a loop device attached to the wall part of a home, etc. for use. A weak current flows through one of the double-layered conductors, and by inserting it into the loop device attached to the wall part, it is connected to the other conductor, and when current flows, the circuit is completed.
[0018] Furthermore, by attaching the devised wire lock device to the front suspension of multiple bicycles or other two-wheeled vehicles, inserting the wire of the first vehicle into the receiving port of the storage device of the second vehicle, and inserting the wire of the second vehicle into the receiving port of the storage device of the third vehicle, etc., it is also possible to fix multiple bicycles or other two-wheeled vehicles and suppress intruders.
Industrial Applicability
[0019] It is a wire lock device with a wire break alarm function that generates a warning sound when cut. Use by many wire lock producers is conceivable. Also, it is a fixture for bicycles and other two-wheeled vehicles that utilizes a wire lock. Utilization by many sellers of bicycles and other two-wheeled vehicles is conceivable.
