DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bell device for issuing an alarm using a bicycle or the like, and more particularly to a method of ringing a bell by playing with a finger.

[0002]

2. Description of the Related Art Generally, in a bicycle or the like, a bell device is attached to a steering wheel as an alarm. When the occupant grips the steering wheel with his hand, for example, by operating the bell device with his index finger, the bell rings and an alarm is issued.

Conventionally, as this kind of bell device, for example, as disclosed in Japanese Utility Model Laid-Open Publication No. 62-132882,
The operating lever protruding to the side of the bell is swung in the fore-and-aft direction with the index finger, and the lever is used to rotate the rotating sesame through the rack and pinion inside the bell, and hit the weight of the rotating sesame on the bell. And ring the bell. Further, as disclosed in, for example, Japanese Utility Model Application Laid-Open No. 2-108686, an operation lever projecting to the side of the bell is vertically swung with an index finger, and this lever operation swings a yajirobe inside the bell. There is a method of hitting the striking portions at both ends of the yajirobee to the bell and ringing the bell.

[0004]

However, in the prior art, each of the bells has a structure in which a rotary striking portion by a gear and a swinging striking portion by a jirobe are accommodated in a bell. However, the structure is complicated and disadvantageous in cost. Moreover, since it has many components, there is a possibility that durability due to corrosion by rainwater may be impaired. In addition, since the operation lever is swung in the forward and backward or up and down directions by the index finger, the handle is in a normal linear shape, and the occupant holds the handle without bending the wrist and lifts the index finger back and forth or up and down. It can be applied when the rocking operation can be strongly performed in the direction, but cannot be applied when the handle has a special shape.

In recent years, an attached front handlebar has been proposed as a handlebar of a sports or competitive bicycle, for example, in Japanese Patent Application Laid-Open Nos. 1-132487 and 1-306386. The front handlebar has an elbow pad, is formed in a U-shaped loop shape in plan view, and is mounted so as to protrude forward from the handlepost.
When the front handlebar is used, the occupant puts the elbows of both arms on the pad and supports the upper body on the handle, thereby reducing arm fatigue. In addition, both arms are extended forward with both sides tightened, and the vehicle runs while steering while holding the handle that has risen upwards with both hands, which naturally leads to a riding position leaning forward. The air resistance inside can be reduced, and the vehicle can run for a long time with little energy loss.

According to the front handlebar,
The occupant stretches both arms straight forward, and folds the wrists of both hands upwards by the handle shape, gripping the handle in a state of weakness. Therefore, in the gripping state of the handle, the thumb and the forefinger are extremely cramped, and it is difficult to operate the forefinger strongly in the forward and backward and up and down directions. For this reason, there is a problem that even if the conventional bell device is applied to the front handlebar, it cannot be operated properly.

SUMMARY OF THE INVENTION In view of the above, the present invention is configured to ring a bell by playing with a finger, thereby greatly simplifying operation and structure, and adapting to an attached front handlebar. With the goal.

[0008]

In order to achieve this object, a bell device according to the first aspect of the present invention is fastened to a resin fixture mounted on a predetermined position of a handlebar and a fixture stand. A metal bowl-shaped bell and a weight that doubles as an operating part at one end of an arm that swings so that it easily bends and returns with a strong spring force, cantilevered at the center in the radial direction outside the bell And placed in a non-contact manner
A swing hammer that strikes the bell against the bell by playing the weight with a finger is provided.

According to a second aspect of the present invention, the bell is disposed near the root of the handle of the handle post, facing rightward. Further, the bell device according to claim 3 is a front handlebar, wherein the handlebar has an elbow pad, is formed in a U-shaped loop shape in plan view, and is mounted to protrude forward from a handle post of the bicycle. Immediately before the right handle that stood above the handlebar,
The bell is disposed vertically close to the right side of the handlebar, and the swing hammer is mounted directly below the center of the bell and attached.

[0010]

According to the first aspect of the present invention, when the rider of the bicycle operates to flip the weight of the swinging hammer with the finger of the hand, the outer arm of the bell flexes freely and a strong spring is applied. It returns by force, and its weight is strongly hit from outside by the bell, and the bell hits from outside and it surely sounds loud.
Therefore, even if the state of the hand holding the handle is cramped,
The bell rings with a simple operation of just hitting the weight of the swing hammer with a finger, so that it is possible to adapt to a front handlebar or the like. The position and direction of the bell with respect to the handlebar are adjusted by the attachment, and the direction of the swinging hammer on the circumference of the bell is arbitrarily adjusted, whereby any one of the thumb, the middle finger, the index finger and the like of the hand can be adjusted. It is also possible to ring the bell using.

According to the second aspect , the bell is turned to the right and the swinging hammer is flipped to the right, so that the bell can be sounded by operating the thumb to close. According to the third aspect of the present invention, when using the front handlebar, the rider puts the elbows of both arms on the elbow pad, stretches both arms straight forward with both sides tightened, and lifts up with both hands. Run while steering while holding the steering wheel.
At this time, the wrists of both hands are folded upwards due to the handle shape, gripping the handle in a state of weakness, the thumb and index finger parts become very cramped, but even in this state play the weight of the swing hammer It is possible to ring the bell properly.

Here, in the bell device 1, the bell 10 can be arranged at any position of the handlebar A in any direction of up, down, left, and right by the mounting tool 2. Also swinging hammer 1
5 can also be rotated around the circumference of the bell 10 and placed in any of its directions. Thus, the bell 10 and the swing hammer 15 can be used when the handle is not only straight but also tilts and bends up and down, right and left, and sounds with the right or left hand.
By adjusting the position and the direction of, it is possible to cope with any case.

In this case, for example, the bell 10 is
An arrangement suitable for sounding is as shown in FIGS. 1 and 2, for example. That is, the bell 10 is disposed near the base of the handle of the handle post A, and the swing hammer 15 is disposed substantially horizontally from the center of the bell 10 and attached. Thus, the bell 10 can be sounded only by flipping the weight 17 of the swing hammer 15 with the right thumb D closed rightward.

Next, the case where the bell device 1 is mounted on the front handlebar of a bicycle for sports or the like will be described.
Referring to FIG. 4, a handle portion will be described. Reference numeral 20 denotes a bicycle, and a main handle bar 22 is mounted on the left and right of a handle post 21.
2 are bent forward and then curved downward in a U-shape, and a drop handle 23 is provided.
The brake lever 24 is disposed at the third position. An attached front handle bar 25 is integrally attached to the front of the handle bar 22 by a clamp device (not shown).

The front handlebar 25 is formed in a U-shaped loop shape in plan view, and an elbow pad 26 is attached to a portion where the handlebar 22 is attached. Also the front handlebar 25
When the left and right bars 25a and 25b extend substantially horizontally forward, and the occupant places both elbows on the pad 26 and extends both arms straight forward, the position of both hands is narrow and rises obliquely upward. It is formed as follows. And right and left handle 2 at the rising part
The front handle bar 25 can be supported by holding the left and right wrists folded upward.

Therefore, as shown in FIGS. 5 and 6, the bell device 1 is attached to the right bar 25b of the front handle bar 25 on the inclined portion 25c immediately before the right handle 27 rising upward. In the bell device 1 in this case, as shown in FIGS. 1 and 2, the bell 10 is vertically arranged close to the right side of the inclined portion 25c, and the swing hammer 15 is arranged directly below, and the handle 27 is moved with the right hand. With the index finger B, the weight 17 of the swing hammer 15 can be easily flipped with the index finger B in a state of being gripped with C.

Next, the operation of this embodiment will be described. First, when the front handle bar 25 is used during bicycle running, the rider places his / her elbows on the elbow pads 26 of the front handle bar 25 and supports the upper body on the handle. In addition, both arms are straightened forward with both sides tightened, and the vehicle runs while steering while holding the handle 27 that has risen upward with both hands, which reduces fatigue of the arms and naturally. The vehicle leans forward to reduce the air resistance during traveling and can travel for a long time with little energy loss.

At this time, the wrists of both hands of the occupant are bent upward due to the shape of the handle, and the handle 27 is held in a posture where the force is released. In this gripped state, the thumb,
Although the index finger part becomes very cramped, the index finger B can be operated so as to be strongly opened to the side even in this state.

Then, with the handle 27 held by the right hand C, the forefinger B is operated so as to be strongly opened outward as shown by the one-dot chain line in FIGS. Then, the index finger B hits the weight 17 of the swing hammer 15 of the bell device 1 as shown by the solid line in FIG. 1, and further pushes the weight 17 outward as shown by the dashed line in FIG. Then, the arm 16 elastically bends outward so as to warp outward to generate a strong spring force, and the index finger B slides off the inclined weight 17 at a position where the arm 16 is bent by a predetermined amount, and automatically comes off. For this reason, the weight 17 is repelled by the spring force of the arm 16 in this case so as to be strongly returned, and the inner corner portion 17a strongly hits the shoulder portion 10b of the bell 10 from the outside. As a result, the bell 10 effectively resonates over the entire area, and sounds clear and loud. In addition, the weight 17 of the swing hammer 15 returns to the original position immediately after hitting the bell 10 and can be repeatedly operated.

In this manner, even when the handlebar 27 of the front handlebar 25 is gripped with both hands, the index finger B of the right hand C can be used.
The bell 10 of the bell device 1 will sound properly only by operating to open the outside. In this case, the index finger B can be repeatedly opened in a short time, and the bell 1 can be operated by this operation.
0 repeatedly sounds, and an appropriate alarm can be issued. In the above-described embodiment, the case where the operation is performed with the handle 27 held by both hands has been described, but it goes without saying that the operation can be performed with the thumb once the right hand C is separated from the handle.

Although the embodiment of the present invention has been described above, the attachment state of the bell and the swinging hammer to the attachment is not limited to the embodiment. For example, the front handlebar 25
On the right side of the inclined portion 25b and the handle post 21,
When the swing hammer 15 is disposed substantially horizontally, the weight 17 can be flipped with the thumb. It goes without saying that the bell device can be applied to handlebars other than the front handlebar. Adjust the position and direction of the bell with respect to the handlebar with the mounting tool, and adjust the direction of the swinging hammer on the circumference of the bell to set it to use any finger such as the thumb, middle finger, index finger of the hand You can also.

[0027]

As described above, in the bell device according to the first aspect of the present invention, a resin fixture attached to a predetermined position of the handlebar, and a metal bowl fastened to the fixture stand. Equipped with a weight bell that also serves as an operating part at one end of the arm that swings so that it can easily bend and return with a strong spring force. And the swinging hammer that strikes the weight on the bell by playing the weight with a finger, so that the bell sounds only by flipping the weight of the swinging hammer with the finger, Operation becomes very easy. For this reason, it becomes possible to adapt to a front handlebar and the like.
Since it is mainly composed of the fixture, the bell, and the swinging hammer, the structure is very simple, compact, and advantageous in terms of cost and durability. In particular, since the arm including the weight that also serves as the operation unit is arranged outside the bell, it is possible to arrange the weight so that the weight is always flipped rightward regardless of the mounting position.

Since the swing hammer is arranged outside the bell, the arm can swing so that it can flex freely and return with a strong spring force. In addition, since the weight is strongly hit from outside by the bending of the arm, the sound from the outside of the bell is surely heard with a loud sound. In addition, the position and direction of the bell with respect to the handlebar are adjusted by the mounting tool,
Further, since the direction of the swinging hammer on the circumference of the bell is arbitrarily adjusted, the bell can be sounded using any finger such as the thumb, the middle finger, and the index finger of the hand.

In the bell device according to the second aspect, the bell is disposed rightward near the root of the handle of the handle post, so that the bell can be sounded properly by operating the thumb of the right hand to close. .

In the bell device according to the third aspect, the handlebar is a front handlebar that has an elbow pad, is formed in a U-shaped loop shape in plan view, and is mounted to protrude forward from a handle post of the bicycle. Immediately before the right handle that rises above the front handlebar, the bell is arranged vertically close to the right side of the handlebar, and the swinging hammer is arranged directly below the center of the bell and attached. Even when using the front handlebar, the bell can be sounded properly by operating the right index finger to open strongly to the side.
