Description

Bell for bicycle}

More particularly, the present invention relates to a bicycle bell, and more particularly, to a bicycle bell having a fixing band fixed to a handle of a bicycle and screwed with a bolt and a nut for fixing the bicycle bell, It is possible to improve the aesthetic feeling and to improve the sound of the bell by forming the side portion of the bell member in a curved shape so that the sound of the bell can be remarkably improved and a clear and louder sound can be produced. .

Generally, the bicycle bell is fixed around the brake lever mounted on the bicycle handle, and when the bicycle operation is in an emergency, the bike user pushes the operating lever or switch of the bicycle bell by finger or pushes it Belong to bicycle safety device.

The bell bell alarm not only protects the bicyclist but also protects pedestrians and other bicyclists around the bicyclist, allowing the bicyclist and pedestrians around the bicyclist to have time to cope Should be used.

As mentioned above, the bell for bicycle is a sound that informs the passenger of the bicycle or the other bicycle rider who is going to pass the street or to pass by the bike, and if the sound is small, the other party can not hear it, However, there is a problem that a conventional species formed in a straight line so as to have the same upper and lower ends can make a sharp and small sound.

In addition, the conventional bell is manufactured by injecting the fixing part and then inserting the nut into the fixing part, which is a waste of time and cost, and there is a problem that the nut is exposed to the outside, .

On the other hand, when the bicycle is operated, the ability to cope with the emergency situation varies depending on the speed of the bicycle, the distance between the pedestrian and the bicycle, and the age of the bicycle user. Are frequently occurring.

For example, users who are somewhat less able to cope with emergency situations such as children or women can not operate the bike bell, and only operate the brake levers and collide with pedestrians who have not been able to ascertain that the bike is approaching . At this time, the pedestrians who do not know that the bicycle is coming to the side where they are located will be seriously injured if they collide with the bicycle.

In this way, it is possible to quickly and easily operate not only users who are not capable of coping with various emergency situations but also ordinary users, and a bicycle bell having a loud sound is needed.

Korean Patent Publication No. 10-2010-0060552 (2010.06.07.)

The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a fastening device for a bicycle, , The manufacturing process can be efficiently improved, the aesthetic feeling can be enhanced, and the side portion of the bellows member can be formed to be bent so that the sound of the bell can be remarkably improved to produce a clear and louder sound, The purpose of the present invention is to provide a bell.

In order to achieve the above object, the present invention provides a bicycle bell comprising: A striking part integrally formed with a lower end of the striking member, a striking protrusion provided under the striking member and rotatable and extending to the side to strik the striking member at a side thereof, and a coil spring provided under the striking protrusion; A fixing part provided below the striking part, the upper part fixing the stencil member and the striking part, and the fixing part integrally including a fixing band for fixing the striking part and the striking part to the handle of the bicycle; Lt; / RTI >

The lower end of the bush member is bent at an angle of 5 to 10 degrees with respect to a straight line extending from the upper end to the lower end.

The fixing part is screwed with a bolt and a nut to fix the fixing band to fit the handle of the bicycle and fix the nut, and the nut is integrally provided inside the fixing part.

In order to insert the nut into the fixing part, the bicycle bell according to the present invention as described above may inject the fixing part by positioning the nut in the fixing part in advance when the fixing part is injected and integrally injecting the nut, The time and cost can be saved as compared with the process of inserting the nut into the stationary part, and the cosmetic nut can not be seen outside the stationary part.

In addition, the lower end of the bellows member is formed so as to be tilted outwardly. When the bell is hit, a sound is emitted through the resonance in the bell. The sound is easier to escape than a normal bellows formed in a straight line, The effect is clear and louder.

Further, the striking portion is configured to be rotatable, so that even if the bike for bike is fixed to any desired position of the bicycle, the striking portion can be rotated so that the handle of the striking projection can be positioned at a convenient place. There is an effect that it is easy.

Also, by fastening the spring fixing bolt to the lower part of the central projection axis provided at the center of the spring house which supports the coil spring from the bottom, the volume of the central projection shaft increases finely outwards and the spring fixing bolt acts as a pillar, The center of the coil spring is deformed due to the external force when the coil spring is fixed by pressing only the coil spring on the central projection axis, It has the effect of always making the same sound when using.

The fastening strip may further include a plurality of fasteners formed at predetermined intervals from the distal end, the fasteners being formed to have a width smaller than the diameter of the fasteners and passing through the plurality of fasteners, Thereby facilitating the movement of the bolt for fixing the fixed band.

This is because, when the bolt is to be fixed to the other fixture in the fixed band made of flexible plastic, the entire bolt is detached from the fixed band by removing the entire bolt It is possible to move the bolt to another fixture through the connector, thereby facilitating the movement of the bolt.

Also, the various member fastening bolts are fixed by fixing bolts penetrating through the blanks, the striking portion and the fixing portion and fastened to the lower portion, and the fastening bolts formed by the fastening bolts formed in the fastening portions , The bellows fastening bolt is prevented from being arbitrarily rotated by the contact of the rotation stopper and the fastening hole after the fastening bolt of the bell-type member is fastened, thereby preventing the bell bell from being disassembled at the time of use, .

Hereinafter, preferred embodiments of the present invention will be described in detail. These embodiments are for further illustrating the present invention, and the scope of rights of the present invention is not limited to these embodiments.

The bicycle bell (1) according to the present invention comprises a bellows member (10); A striking protrusion 21 provided below the stencil member 10 and rotatable and extending to the side so as to strike the stencil member 10 from a side surface thereof and a coil spring A spring housing 23 which integrally includes a coil spring 22 for supporting the coil spring 22 from below and a spring fixing bolt 23 which is fastened to a lower portion of a central projection shaft 23a provided at the center of the spring house 23, (20) further comprising: a hinge portion (24); And a fixing belt 31 integrally provided at a lower portion of the lower portion of the striking portion 20 to fix the bell-type member 10 and the striking portion 20, (30); / RTI >

A tongue member fastening bolt 11 for fastening the cichlid member 10 to the striking portion 20 and the fixing portion 30 and a fastening member fastening bolt 11 for fastening the tongue member fastening bolt 11 to the fixing portion 30 And a fastening bolt 12 fastened to the fastening bolts 11 at the lower portion of the fastening bolt 11. A rotary fastening portion 11a cut at a predetermined interval is formed at a lower side of the fastening bolt 11 And a locking hole 11b protruding from the fixing portion 30 to correspond to the rotation stopping portion 11a is formed at a portion of the fixing portion 30 where the fixing member 11 is inserted, Prevent rotation after tightening.

The lower end of the bush member 10 is bent at an angle of 5 to 10 degrees with respect to a straight line extending from the upper end to the lower end of the bush member 10, . In addition, the lower end may be extended in the vertical direction of the lower side.

The reason why the lower end is formed to be tilted outwardly is that when a bell is hit, a sound is emitted through the resonance in the bell. It is easier to escape the sound than a normal bellows formed at the upper end and the lower end, This is because it has the effect of going out.

In order to compare the loudness of the bell for the bicycle, the bell bell example 1 of the present invention and the bell case comparative example 1 for the ordinary bicycle were made to sound respectively, and then repeatedly measured three times with a decibel meter, Respectively.

(Table 1) Comparison of sound volume of bell for bicycle

As shown in Table 1 above, Example 1 was measured to be 6 dB higher than Comparative Example 1, and it was found that the bicycle bell of the present invention was louder than the general bell bell .

Bicycle bell (1) is a sound that tells the cyclist to avoid the passerby or other cyclists who pass by the street, or to pass by, and if the sound is small, the other party can not hear it, . Therefore, the bicycle bell (1) of the present invention is designed to be suitable for the bicycle bell (1) because of its clear and loud sound.

In this case, if the lower end is inclined 5 to 10 degrees outwardly, if it is more than 10 degrees, there is a problem that when the bell is hit, the sound becomes too large to cause discomfort and misunderstandings of the other party. There is no significant difference from the general type formed in a straight line so that there is a problem that a sharp and small sound can be produced.

It goes without saying that the rubber member may be further provided on the upper side and the lower side of the bellows member 10 when it is tightened with the bellows bolts 11. This can prevent direct contact of the crimping bolts 11 with the biting member 10, thereby improving the sound of the bell and helping to produce a clear and loud sound.

The hitting protrusion 21 includes a handle 21a and an impact protrusion 21b. Normally, the hitting protrusion 21 and the different member 10 are separated from each other by a predetermined distance, When the handle 21a is applied with an external force, the impingement protrusion 21b hits the bell-type member 10 by the coil spring 22 provided under the bell protrusion 21, do.

Further, when only the coil spring 22 is press-fitted and fixed to the central projection shaft 23a provided at the center of the spring house 23 supporting the coil spring 22 from the bottom, The center of the coil spring 22 is deformed by an external force applied to the striking protrusion 21 so that the striking part of the stencil member 10 is changed to change the sound of the bell for the bicycle. The central protruding shaft 23a is further tightened with the fixing bolt 24 so that the volume of the central protruding shaft 23a increases finely outwardly, Since the fixing bolt 24 serves as a pillar, the problem described above can be solved, and the same sound can be always produced when the bicycle bell 1 is used.

The hitting portion 20 is rotatable so that the hitting portion 20 is rotated even if the bike 1 is fixed to a desired position of the bicycle so that the handle 20 21a can be located in a convenient place for use, so that it is easy to use the bike 1 for bicycle.

The fixing part 30 is screwed with a bolt 32 and a nut 33 to adjust the fixing band 31 to fit the handle of the bicycle and fix the nut 33, 30, respectively.

In this case, the upper portion of the fixing portion 30 fixing the cotthetic member 10 and the hitting portion 20 may be made of a plastic having a high strength, and the fixing belt 31 may be fixed to the handle of the bicycle The bolt 32 and the nut 33 may be made of a rigid material including a metal for increasing the fixing force. The bolt 32 and the nut 33 may be made of a material having a lower strength than the upper portion, The nut 33 may be positioned in the fixing part 30 and injected integrally with the fixing part 30 when the fixing part 30 is injected to insert the fixing part 30 into the fixing part 30. After the fixing part 30 is injected, It is possible to save time and cost compared with the process of inserting the nut 33 into the fixing part 30 and the beauty nut feeling 33 can be seen outside the fixing part 30, have.

The fixing belt 31 is provided with a plurality of fixing holes 31a formed at predetermined intervals from its distal end and the width of the fixing holes 31a is smaller than the diameter of the fixing holes 31a, 31b of the fixing belt 31. The fixing bolt 31 can be easily moved by fixing the connecting belt 31b.

The fixing belt 31 is composed of the flexible plastic by having a connecting hole 31b connecting the plurality of fixing holes 31a which are the holes into which the bolts 32 are inserted so as to fix the fixing belt 31, It is possible to move the bolt 32 to the other fixing member 31a through the connecting hole 31b without removing the entire bolt 32 when the bolt 32 is to be fixed to the other fixing member 31a, There is an effect that it is easy to move.

At this time, it is needless to say that the predetermined interval of the fixture 31a may be 0.2-0.5 mm. If the spacing between the plurality of fasteners 31a is greater than 0.5 mm, it is difficult to finely adjust the spacing when the bicycle bell is fixed to the bicycle, There is a problem that the interval is too close and the manufacturing process is not efficient.

The clamping bolts 11 are fixed by fixing bolts 12 passing through the clamping member 10, the striking unit 20 and the clamping unit 30, 11b of the rotary member 11 and the stopper 11b formed in the fixing member 30 corresponding to the rotation stopper 11a formed in the rotary member 11, It is possible to prevent the rotating bolts 11 from being arbitrarily rotated by the contact of the spherical member 11b, thereby preventing the bicycle bell from being disassembled in use, so that the fixing force can be increased.

At this time, the preset interval at which the rotation stopper 11a is formed in the clamping bolt 11 is the same as the height of the stopper 11b formed in the fixing part 30 corresponding to the rotation stopper 11a Of course.

The bicycle bell 1 of the present invention formed as described above allows the user to position the fixed band 31 at a desired position of the bicycle and insert the bolt 32 into the fixing hole 31a, And is screwed to the nut 33 integrally provided. The knob 21a of the knocking protrusion 21 is moved to a convenient location by rotating the knocking unit 20 so that the user adjusts the position of the knob 21a and when the user applies an external force to the knob 21a, The collision protrusion 21b of the striking projection 21 strikes the bellows member 10 by the coil spring 22 provided at the lower portion of the protrusion 21 so that a sound is emitted.
