Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a bell device, and particularly to a bell device suitable for use in bicycles, tricycles, etc.

"Prior Art" It is well known that bell devices have been used in bicycles, tricycles, and the like. This bell device is
Usually installed on the right side of the handle, the bell rings when the operating lever is pulled back toward the rear in the direction of travel, and the bell also rings when the operating lever is returned to its original position by a spring. It's getting old.

Furthermore, the mounting bracket for attaching the bell device to the handle usually consists of a band wrapped around the outer periphery of the handle, engagement holes drilled at both ends of the band, and engagement holes drilled at both ends of the band. a connecting plate that is engaged with and surrounds the handle together with the band; a cover that accommodates a connecting portion between the connecting pirate and the band, abuts the handle, and has the bell device attached to the top surface; A bolt is provided that is passed through the front surface of the cover and screwed into the connecting plate, and tightens the connecting plate to fix the band and the cover to the handle.

``Problem to be solved by the invention'' However, in cases where the operating lever of the transmission mechanism is mounted on the right side of the steering wheel, the above-mentioned bell device will be mounted on the left side of the steering wheel. By pushing it forward in the direction of travel, it will ring a bell. Therefore, depending on whether the bell device is attached to the right or left side of the handle, the operating direction of the operating lever is reversed, which impairs operability.

In addition, when attaching the mounting bracket with the above configuration to the handle, first wrap the band around the outer circumference of the handle, and then engage both ends of the connecting plate into the engagement holes drilled at both ends of the band. let Next, while maintaining this state, cover the connecting portion with the cover, pass a bolt through the front surface of the cover, screw the bolt into the connecting plate, and tighten the bolt.

Therefore, when putting the cover over the above-mentioned connecting part, it is necessary to hold both ends of the connecting plate in a state where they are engaged with the engagement holes of the band using fingers or a tool. It is necessary to open the bottom surface so that fingers and tools can be inserted there. As a result, the connection structure inside the cover is exposed to the outside, although it is not noticeable.
I didn't like it.

"Means for Solving the Problem" In view of such circumstances, the present invention includes a rotary operation plate that is rotatably supported on a support shaft in forward and reverse directions, a bell attached to the support shaft, and the rotary operation plate. and a bell, and a striking member provided on the other side through a flexible member so as to be swingable,
The protrusion collides with the flexible member or the striking member by rotating the rotary operation plate in forward and reverse directions, and the striking member is swung to strike the bell.

Further, if necessary, an operating lever may be provided on the rotary operating plate, and the operating lever may be held at a predetermined neutral position between the rotating operating plate and the support shaft, and the operating lever may be moved forward or backward from the neutral position. Spring means may be provided to permit rotation to.

Further, the support shaft is attached to a mounting bracket, and the mounting bracket is connected to a band wrapped around the outer periphery of the handle, engagement holes drilled at both ends of the band, and an engagement hole formed at each end of the band, as in the conventional case. a connecting plate that is engaged in each of the engagement holes and surrounds the handle together with the band; and a connecting plate that accommodates a connecting portion between the connecting plate and the band, is in contact with the handle, and has the support shaft on the upper surface. and a bolt that is passed through the front of the cover and screwed into the connecting plate, and tightens the connecting plate to fix the band and the cover to the handle. includes a mounting hole formed at the lower end of the band, and a lid that is fitted into the mounting hole and closes the lower surface of the cover by covering the engagement portion between the lower end of the band and the connecting plate. It is designed to have a body.

"Operation" According to the above configuration, by directly rotating the rotary operation plate in the forward and reverse directions, or by rotating the rotary operation plate in the forward and reverse directions from the neutral position using the operation lever provided thereon, the above-mentioned protrusion and Since it is possible to collide with the flexible member or the striking member and swing the striking member to strike the bell, the rotary operation plate can be rotated in the desired direction regardless of the installation conditions of the bell device. You can ring the bell.

In addition, since the lower surface of the cover can be closed by fitting the lid into the mounting hole formed at the lower end of the band, the connecting structure inside the cover is not exposed to the outside and the appearance is improved. It can be made into a good one.

"Example" The present invention will be explained below with reference to the illustrated example.
In FIG. 1, the bell device 3 attached to the handle 1 via the mounting bracket 2 consists of a disk-shaped board 4 attached to the top surface of the mounting bracket 2, and a support shaft erected at the center of the board 4. 5, and a rotary operation plate 6 is rotatably supported on the support shaft 5 in forward and reverse directions.

By sandwiching the rotary operation plate 6 between the base plate 4 and the wing-shaped arm 11 with a slight gap, the rotary operation plate 6 is prevented from wobbling in the axial direction, and the hemispherical shape The winged arm 11 is housed inside the bell 8 of the bell 8.
The lower end face of the rotary operation plate 6 faces the outer circumference of the upper end face of the rotary operation plate 6 with a predetermined gap therebetween.

On the upper end surface of the rotary operation plate 6, a large number of protrusions 12 are formed protruding on a circle centered on the rotation center of the rotary operation plate 6 at a position inside the bell 8. At both ends of 11,
A striking member 14 is attached via a coil spring 13 as a flexible member. Note that the wing-like arm 11 and the coil spring 13 may be made of the same spring material, or the coil spring 13 may be made of a plate-like flexible member. In particular, when the coil spring 13 is a plate-like flexible member, the wing-shaped arm 11, the flexible member, and the striking member 14 may be integrally formed of synthetic resin.

Each of the protrusions 12 is arranged at a position where it can collide with the striking member 14 even when the rotary operation plate 6 is rotated in either the forward or reverse direction, and each protrusion 12 is formed into a triangular prism shape. The top part is arranged radially inward.

Therefore, when the rotary operation plate 6 of the bell device 3 attached to the handle 1 is rotated in either the forward or reverse direction and the respective protrusions 12 collide with the striking member 14, the triangular prism of each protrusion 12 The shape allows the striking member 14 to be displaced radially inward,
Furthermore, when the engagement between the protrusion 12 and the striking member 14 is disengaged, the restoring force of the coil spring 13 causes the striking member 14 to be displaced radially outward to strike the inner surface of the bell 8. can.

In this way, the bell 8 can be sounded by rotating the rotary operation plate 6 in either the forward or reverse direction, so the operation direction can be changed even if the bell device 3 is attached to either the left or right side of the handle 1 as in the conventional case. Therefore, the operability can be improved.

Note that the protrusion 12 does not necessarily need to collide with the striking member 14, and may be configured to collide with the coil spring 13 to swing the striking member 14, thereby striking the inner surface of the bell 8.

Next, the mounting bracket 2 for attaching the bell device 3 to the handle 1 includes a band 30 wrapped around the outer circumference of the handle 1, as shown in FIGS. 2 and 3. Engagement hole 3 drilled in
Both ends of the connecting plate 32 are engaged with 1a and 31b, respectively.

The connecting portion between the band 30 and the connecting plate 32 is housed in a cover 33, and the substrate 4 and the support shaft 5 are placed on the upper surface of the cover 33.
is installed. Then, by screwing the bolts 34 passed through the front surface of the cover 33 into the connecting plate 32 and tightening them, the connecting plate 32 and the band 30 are pulled and the band 30 is tightened.
The mounting bracket 2 is fixed to the handle 1 by closely contacting the handle 1 with the arc-shaped notch 33a formed on the side surface of the cover 33.

By the way, the bolt 34 is connected to the connecting plate 32.
When screwing into the band 30, use your fingers or a tool to insert both ends of the connecting plate 32 into the engagement holes 31a, 3 of the band 30.
Since it is necessary to cover the connecting portion with the cover 33 while keeping the cover 33 engaged with the cover 1b, the bottom surface of the cover 33 is opened so that fingers or tools can be inserted therein. . As a result, the connection structure inside the cover 33 is exposed to the outside.

In order to solve such a drawback, in this embodiment, a device is attached to the lower end of the band 30, at a position opposite to the cover 33 of the engagement hole 31b, so as to be continuous with the engagement hole 31b. forming a hole 35;
The cover body 36 is fitted into the mounting hole 35 and the cover 3 is attached.
The bottom surface of 3 is closed. The lid body 36 includes a recess 36a for accommodating the engagement portion of the lower end of the band 30 and the connecting plate 32, and also includes a protrusion 36b, which can be press-fitted into the mounting hole 35. The lid body 36 is attached to the band 30 by.

Next, FIG. 4 shows another embodiment of the present invention. In this embodiment, contrary to the above embodiment, a striking member 114 is attached to the upper end surface of the rotary operation plate 106 via a coil spring 113. When attached, a large number of protrusions 112 are formed on the inner peripheral surface of the bell 108 to collide with the striking member 114. It is clear that even in such a configuration, the same effects as those of the above embodiment can be obtained.
