JPH10203440A - Anti-theft preventive alarm device of bicycle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To surely operate an alarm device even when a locking device is broken by generating the alarm sound and light by an alarm when the locking device is broken and the current directly flows in the alarm. SOLUTION: When a locking device 5 is disconnected, a control part 4 detects the disconnection, and the current flows in a loud speaker 105 through wires 4A2, 106 of a handle 2. The loud speaker 105 is symmetrical in the right-to-left direction, and has the fail-safe function where one is operable even when the other is broken. When a control panel 9 is broken, the loud speaker 105 generates the alarm sound, and even when the locking device 5 is connected, the loud speaker 5 singly generates the alarm sound irrespective of the control panel 9. The light is generated from a light emission part provided on the control panel 9.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an alarm device for a motor-equipped bicycle.

[0002]

2. Description of the Related Art With the spread of pedal-powered bicycles in recent years, there has been a remarkable demand for security management against theft and the like. For this reason, the user is configured to easily remove the storage battery after driving. The reason for this is to prevent others from intentionally destroying the key and directly connecting the electric current to operate.

[0003]

However, in the case of shopping or the like, since the storage battery is not removed at the bicycle parking lot, the probability of being stolen is high.

An object of the present invention has been made in view of such a problem, and an object of the present invention is to propose a configuration in which an alarm device can be reliably operated even if a locking device is destroyed.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is an alarm device capable of supplying a current applied from rotation of a pedal of a bicycle. , An electric control means, a locking device capable of preventing the operation of the bicycle, and an alarm device, which generates a warning sound and a light when the locking device is destroyed and the current is directly connected to the alarm device. It was configured to be.

[0006] The alarm device is composed of a loudspeaker capable of changing the tone, and is mounted inside the left and right grips of the steering wheel. The grip is screwed to the handle, and the surface of the screwed portion is surrounded by a cover.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram of a pedal-powered bicycle according to one embodiment of the present invention. In the figure, 1 is a frame main body, 2 is a handle, and an alarm device of the present invention is attached to both ends of the handle 2. Further, there is a storage unit 3 for generating and storing electric energy by rotation of the pedal and a control unit 4 for performing electric control. The control unit 4 is configured to automatically start the prime mover 8 when a torque load on wheels is increased on a slope or the like. ing. Reference numeral 5 denotes a locking device, and the frame 1
As shown in FIG. 2, a cylinder-shaped lock 5 is fitted in the inside of the lock 5. The battery 3 and the control unit 4 are housed inside the frame 10 and can be taken out by opening the door 3A. Reference numeral 9 denotes a control panel.
This will be described with reference to FIG.

FIG. 3 is a detailed explanatory view of the alarm device.
The cross section of the end of the handle 2 is shown, 101 is a grip, and the handle 2 and the grip 101 are screwed together like a screw portion 101A. The periphery of the grip 101 is covered with a cover 102, and it is not apparent from the appearance that the grip 101 has been joined. The material is a silicon-based rubber product, and colors and patterns may be arranged depending on hobbies. Reference numeral 103 denotes a lid of the grip, which is made of a material such as SPCC which is an iron material. The arrow a in FIG. 3 indicates a plurality of holes 1 in the lid 103 as shown in FIG.
03A is open. Inside the grip 101,
A loudspeaker 105 is provided. An electric wire 106 is connected to a power supply and a control unit (not shown). The outside of the lid 103B is covered with a plug cover 104, and the material is synthetic leather.

The above configuration will be functionally described with reference to FIG. 1. First, when the locking device 5 is disconnected, the control unit 4 detects the disconnection and detects the loudspeaker 10 through the electric wires 4A2 and 106 of the handle 2.
Send current to 5. The loudspeaker 105 emits a predetermined sound,
This sound passes through the hole 103A, propagates through the stopper cover 104, and transmits the sound to the outside.

The loudspeaker 105 is symmetrical,
This is a fail-safe function that operates even if one is broken.

The grip portion is entirely waterproofed. For example, the threaded portion is screwed with a waterproof seal interposed therebetween, and the resin-based waterproofing is provided also in the circular gap between the plug cover 104 and the lid 103. Hardened with adhesive.

FIG. 5 is a plan view of the control panel 9. The control panel 9 has a display section 9 A and an operation section 9.
D and an alarm stick 9B. If the control panel 9 is broken, first,
The loudspeaker 5 emits an audible alarm independently of the control panel 9 even if the loudspeaker 5 emits an audible alarm and then the locking device 5 is connected.

Referring to FIG. 5 in detail, the light emitting portion 9C emits light when the locking rod 5 is connected by raising the alarm stick 9B at a right angle as shown in FIG. Display 9
A is an LCD, and the back surface (not shown) is always illuminated by a backlight, so that it can be sufficiently viewed even in strong sunlight or a dark place. In the operation unit 9D, for example, each time the push button A is pressed several times, the tone changes in a loop, and the type is displayed on the display unit 9A.

[0015]

As described above, since the present invention is configured, when a theft is encountered, a warning sound or light is emitted, thereby avoiding damage at a bicycle parking lot or the like during shopping. In addition, it is rich in sports and entertainment, and depending on the design, the area of hobbies can be expanded. The interchangeability increases design flexibility. Since it is a fail-safe function, even if one is destroyed, the other operates to ensure safety.
