The present invention relates to a multi-functional turn signal lamp for a bicycle, more particularly, to a multi-functional turn signal lamp for a bicycle that can be used in a state of being fixed or detachably attached to an end portion of a handle bar of the bicycle and can multiply perform a turn indicator function or a brake signaling function, a front lighting function or an on-and-off lighting function for signaling a user's position because multiple and multi-line LEDs (Light Emitting Diode) are mounted. Furthermore, the multi-functional turn signal lamp can obtain a width indicator effect of the bicycle from LED lighting so that it can enable the user to easily distinguish forward and backward objects and can enable the use of a portable repository and charging of a portable device.
Recently, as many bicycle paths have been opened, the people who ride a bicycle are increasing. However, a handle bar of a conventional bicycle provides merely a simple function to a rider with regard to adjusting a direction of the bicycle because a grip part is only simply installed at the handle bar.
Thus, the conventional bicycle has no means for signaling a rider's moving direction to another rider who comes on from the front or the back.
That is, in the case of a car, since a turn signal lamp is installed at the car, a rider can easily signal his or her driving direction to another rider who comes on from the back via a means for turning on and off the right or left turn signal lamp. However, it is problematic in that the bicycle has no means for signaling the rider's driving direction to another rider who comes on from the back.
Also, even though a turn signal lamp of the conventional bicycle is presented, it is for a user difficult to distinguish directions because such a turn signal lamp has a small width.
In particular, it is difficult for the existing turn signal lamp to substantially control or display a direction upon sudden stop or stop because there is no brake lamp, and thus there is the high risk of a rear collision.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art. An object of the present invention is to provide a multi-functional turn signal lamp that can be used in a state of being fixed or being detachably attached to an end portion of an existing handle bar of a bicycle by mounting a battery thereto, wherein the battery can be charged even in a state of the turn signal lamp being separated from the handle bar in the case where the turn signal lamp is detachably attached to the handle bar. Furthermore, by installing multiple and multi-row LEDs, the multi-functional turn signal lamp for the bicycle can perform complex functions such as a direction indicating function, a front lighting function, a brake lamp function, a speed controlling function and the like.
Also, another object of the present invention is to provide a multi-functional turn signal lamp for a bicycle, which is configured such that, in a case where the people ride each bicycle as a group, each LED part 6 may be installed to emit a specific beam having the same color so that the group can be distinguished from other riders or groups, and riding can be entirely controlled and led, thereby enabling stable group riding.
In particular, a further object of the present invention is to provide a multi-functional turn signal lamp for a bicycle capable of increasing a width indicator effect of the bicycle resulting from turning on of a lighting lamp and visual images for stop signals and stability, and capable of selecting a night lighting function by adopting LEDs arranged at both sides of a front portion as high luminance LEDS for controlling intensity.
Also, yet another object of the present invention is to provide a multi-functional turn signal lamp for a bicycle that is convenient to operate because the turn signal lamp is located at a handle bar, and has a lighting function showing a light source width largely improved compared to that shown from an existing lighting function because beams are irradiated from each outside of both sides of the handle bar, the multi-functional turn signal lamp irradiating a beam upon changing a direction.
In order to accomplish the above objects, the present invention provides a multi-functional turn signal lamp for a bicycle that is configured to be fixed to an end portion of a handle bar of an existing bicycle and is able to be charged via a charging terminal by separating a module embedded with a battery, wherein a light source display arranged at the end portion of the handle bar is made of acrylic (translucent PC) and the like, and multiple LEDs are installed so as to irradiate beams to the front or so as to serve as a turn signal lamp.
Also, the present invention provides a multi-functional turn signal lamp for a bicycle that can enable a user to listen music or can receive a power source by installing a charging terminal, a portable device terminal and a speaker for additional functions.
According to the present invention, it is advantageous in that a multi-functional turn signal lamp for a bicycle according to the present invention can be used in a state of being fixed or being detachably attached to an end portion of a handle bar of an existing bicycle, a turn signal lamp and a signal sound can be simultaneously operated, or turning on and off (emergency/warning) and speed accelerating or decelerating signals can be displayed by pushing a suitable key upon riding the bicycle, and an audiovisual effect for enabling lighting of a brake lamp and the generation of a warning sound carn be generated when a rider holds on to a brake lever of the handle bar.
Also, according to the present invention, it is advantageous in that a width indicator effect of a bicycle and visual images for stop signal and stability can be increased by turning on of a lighting lamp when a rider rides the bicycle at night, and a night lighting function can be selected by adopting LEDs arranged at both sides of a front portion as high luminance LEDs for controlling intensity.
Also, according to the present invention, it is advantageous in that a portable device can be continuously used via a charging terminal installed at a key part using a connection jack even upon discharge of the interchangeable portable device such as a smart phone.
Also, the present invention can enable a module to be easily separated from a grip part by simply pulling a ring installed at a lock cover.
Also, the present invention can enable a rider to listen to music by inserting a memory containing a sound source desired by the rider into an insertion terminal because the insertion terminal for a portable repository is installed, and can enable the user to listen to music via a portable music player such as a smart phone or the like.
A first exemplary embodiment of the present invention will be hereinafter described in detail with reference to accompanying
The on/off key 1 is composed as an alternating key in which turning on is performed when the on/off key is pushed once, and turning off is performed when the on/off key is pushed once again.
When the on/off key 1 is pushed once for turning on, LEDs 6a, 6c of the LED part 6 are turned on, thereby showing a side light. At this time, LED 6c is in a tail lamp state (see
Furthermore, the on/off key 1 may enable a user to listen to music when the output key 2 is pushed in an on state. When the turning on and off/accelerating or decelerating key 3 is selectively pushed, the LEDs 6a are turned off, thereby showing a warning or emergency state. When the decelerating key is pushed, the LED is slowly turned on and off from top to bottom, and when the accelerating key is pushed, the LED is rapidly turned on and off, thereby showing acceleration.
At this time, it is preferable that a turn on and off speed rate between the acceleration and deceleration be 1:2 or 1:3, and the turn on and off speed rate is composed so that a suitable signal sound can be generated according to each circumstance.
The turn signal lamp according to the present invention is configured such that when the headlamp key 3d is pushed, a high luminance LED 6b is turned on, and when the user holds on to the handle brake 3b, the brake lamp 6c is only turned on.
Furthermore, the LED part 6 is installed at a circumferential portion of an inner circle of a cover 16 to have regular intervals or multi-rows.
A length on one side of the LED part 6 of the present invention from the center of the handle bar 10 may range from 100 to 500 rm.
The operation of the present invention configured as descried above will be described.
With regard to the existing handle bar of the bicycle, the turn signal lamp may be fixed to the handle bar 10 and may be used in a state of a battery being mounted. In a case where the turn signal lamp is detachably attached to the handle bar, as shown in
Here, the kind of the handle bar 10 of the bicycle includes the flat bar form (including a riser bar form and an H-like bar form) and the drop bar form (including a bullhorn bar form and a moustache bar form) as shown in
That is, when the LED part 6 of the present invention is installed at a back mirror, or is applied to the drop bar form, the LED part may be configured to be mounted via a separate multi-link.
The battery part 12 is inserted into an inner side of the grip part 11 so that power can be supplied to each part. The constitutive elements from the battery part 12 to the cover 16 are integrally formed so that the battery can be charged via a general charging means by opening the cover 16 to separate the battery part 12.
Also, a power terminal is installed in the inner side of the grip part 11 so that another power terminal of the battery part 12 can automatically come into contact with the power terminal of the inner side of the grip part 11 when the battery part 12 is inserted into the grip part 11, thereby enabling power supply.
As such, when the on/off key 1 of the key part 4 is pushed once in a state where the battery part 12 is inserted into the grip part 11 to be completely closely fixed to the inner side of the grip part 11 by rotating the cover 16, power is supplied from the battery part 12 to the LED part 6 and thus the LEDs 6a, 6c of the LED part 6 are turned on so that a beam can be emitted via the lighting part 14 installed at an outer side of the LED part 6.
Accordingly, the LED part 6 of the present invention may perform a day and night warning function, a driving state displaying function and a brake lamp function. When the turning on and off/accelerating or decelerating key is pushed by selecting a turning on and off/accelerating or decelerating function, the turning on and off function is changed to the accelerating or decelerating function. Thus, the LED part is slowly turned on and off from top to bottom upon deceleration, or is rapidly turned on and off in an opposite direction upon acceleration.
During the night, as a lamp of the LED part 6 is turned on, a wide width effect of the bicycle and a visual image effect for a stop signal and stability can be increased. Furthermore, as high luminance LEDs for controlling intensity are adopted on both sides of a front portion, the turn signal lamp for the bicycle capable to selecting a night lighting function may be provided.
That is, in the nighttime, when the on/off key of the key part 4 is pushed, as shown in
Furthermore, when the turning on and off/accelerating or decelerating key 3 of the key part 4 is pushed once, the LEDs 6a are turned on and off by the control of the control part 5, thereby serving as a turn signal lamp. When the accelerating or decelerating key 3 is pushed by selecting the acceleration or deceleration function, the turning on and off function is changed to the acceleration or deceleration function so that the LEDs 6a can be sequentially turned on from top to bottom in order of A-B-C-D and can be divided into turn on and off speeds, and at the same time, the LED can also enable a buzzer to generate a suitable signal sound according to each circumstance by being linked with the buzzer.
Hand signals generally used upon riding a bicycle are applied to a selective turning on or off of the LED part 6 of the present invention as shown in
Also, when the headlamp key 3d of the key part is pushed as needed, the high luminance LED 6b is turned on, thereby serving as a head lamp that illuminates the front. The high luminance LED 6b may be configured such that about two or three radiation intensity control-type LEDs are installed at the front.
When the person who rides the bicycle looks at the LED part 6, the LED part is configured to be in a state as shown in (B), thereby enabling the prevention of glariness.
In particular, in the present invention, in a case where the people ride each bicycle as a group, each LED part 6 may be installed to emit a specific beam having the same color so that the group can be distinguished from other riders or groups, and riding can be entirely controlled and led, thereby enabling stable group riding.
Furthermore, the LED part may be also installed to emit a beam to a side direction (left and right directions) of the handle bar.
Here, the speaker 8 is integrally installed with the cover 16 and is connected to the substrate 13 installed between the battery part 12 and the LED part 6 so that a signal transmitted from the portable repository inserting part 9 resulting from the control of the control part 5 can be outputted via the speaker 8.
Furthermore, as shown in
Also, since the portable repository inserting part 9 is installed at one side of the charging terminal 1a of the cover 16, when the user inserts a memory into the portable repository inserting part 9 in an on state of the output key 2, he or she can listen to desired music via the speaker 8.
Meanwhile, in a case where it is intended to simply ride the bicycle in a stop state of all the functions, power is blocked when the key is pushed once again in an on state of the on/off key 2 of the key part. Thus, as the LED part 6 is turned off, other memory functions, a music outputting function and the like are stopped.
As shown in
Meanwhile, as described above, the turn signal lamp of the present invention may be applied to the handle bar of the bicycle and may enable the execution of general functions by installing the LED part 6 of the present invention at a back mirror (rear view mirror).
A second exemplary embodiment of the present invention will be hereinafter described.
Also, in a case where it is intended to turn on and off the head lamp, the head lamp is turned on when the headlamp key is short-pushed, and the head lamp is turned off when the headlamp key is short-pushed once again.
(C) of
Here, the turn signal lamp of the present invention has a charge displaying function operated in such a manner that about one LED of the LED part 6 is turned on upon charging, thereby displaying charging.
(D) of
Four LEDs of the LED part 6 of the lighting part 21 are simultaneously turned on and off according to control of the control part 5 upon operating of the turn indicator key 2a.
Here, grooves having a regular depth are formed at both ends of the grip part 37 made of a rubber material, and a clamp 40 is mounted to each of the grooves. Thus, when the clamp is coupled in a state where the grip part 37 is inserted into the handle bar 50 of the bicycle, the grip part 37 made of the rubber material is firmly tightly fixed to the handle bar 50 of the bicycle by the clamp 40.
That is, when the pin 34a is moved to the right, the hook top 22a is moved downwards, and the hook bottom 22b is moved upwards due to the property of a triangular structure of the inside of the hook bottom 22b and the hook top 22a, so that the module 22 is separated from the grip part 37.
At this time, a spring 22c elastically installed between the hook top 22a and the hook bottom 22b is in a compression state.
Then, when the module is connected to the grip part 37 again, the hook top 22a and the hook bottom 22b are returned to each original position due to a restoring force of the spring 22c, and the module 22 is firmly connected to the grip part 37 due to the projection part.
That is, when pulling the ring 34 after bending the ring to the right, a hook 31 is moved upwards and downwards as the direction of an arrow, the locking state is released.
When the module 22 is attached to or detached from the grip part, a projection structure of the FPCB 38 and a pogo pin 39 enables the module to be attached to or detached from the grip part. The grip part and the module are electrically connected to each other so that signals can be transmitted or received.
That is, the grip part is connected to a circuit of the module 22 via the FPCB 38 and the pogo pin 39 upon operating of functional buttons of the grip part 37, thereby performing a function via the lighting part 21.
As shown in
A third exemplary embodiment of the present invention will be hereinafter described in detail with reference to
Reference numeral 58, which is not described in the drawing, refers to a clamp for firmly fixing the grip part 51 to the handle bar 59 of the bicycle by being installed at both ends of the grip part 51.
Reviewing an operational state of the key part, when the power and headlamp key 52 is long-pushed, power is turned on, and at the same time, one mood lamp is turned on. Meanwhile, when the power and headlamp key is long-pushed once again, power is turned off.
Also, in a case where it is intended to turn on or off the head lamp, the head lamp is turned on when the power and headlamp key is short-pushed, and the head lamp is turned off when the power and headlamp key is short-pushed once again.
Furthermore, reviewing an operational state of the brake lamp key 54, when the brake lamp key is short-pushed, the brake lamp is turned on for 5 seconds and is then turned off. When the brake lamp key is continuously pushed, the brake lamp is continuously turned on, and when the pushing state of the brake lamp key is released, the brake lamp is turned off.
Here, since the turn signal lamp of the present invention has a charge displaying function, one LED is turned off upon charging, thereby showing charge displaying.
Meanwhile, reviewing an operational state of the turn indicator key 53, when the turn indicator key is short-pushed for operating the turn indicator, the turn indicator flickers for 5 to 10 seconds and is then turned off. Furthermore, when the turn indicator key is long-pushed once for enabling a mood lamp function to be performed, three LEDs are turned on, and when the turn indicator key is long-pushed once again, three LEDs are turned off.
The multiple LEDs in the silicon cap 73 are simultaneously turned on and off according to control of the 210 control part upon operating the turn indicator key 53.
Here, a groove having a fixed depth is formed at both ends of the grip part 51 made of a rubber material, respectively. When coupling of the clamp 58 is performed in such a manner as to mount the clamp 58 to the groove and insert the grip part 51 into the handle bar of the bicycle, the grip part may be tightly fixed to the handle bar of the bicycle via the clamp 58 because the grip part 51 is made of the rubber material.
In a case where it is intended to separate the module 72 from the grip part 51, when the upper and lower portions of the silicon cap 73 are held and pressed with the fingers, the upper and lower portions of the silicon cap 73 are pressed in the direction of an arrow, and the top hook 71a and the bottom hook 71b liked with a pressing portion are moved to the center.
Accordingly, the top hook 71a and the bottom hook 71b of the hook portion 71 are separated from the projection part, thereby occurring separation of the hook portion 71. Thus, the module 72 including the silicon cap 73 is entirely separated from the grip part 51 to the outside.
At this time, the spring 71c elastically installed between the hook top 71a and the hook bottom 71b is pressed by the hooks and thus is maintained in a compressed state.
Accordingly, as shown in
Then, when the module 72 is connected to the grip part 51 again, the hooks are moved upwards and downwards by a restoring force of the spring 71c compressed between the top hook 71a and the bottom hook 71c and are held by the projection part when the user separates his or her hand from upper and lower portions of the silicon cap 73 after connecting the hook portion 71 to the grip part 51 in a state of pressing the upper and lower portion, thereby enabling the module 72 to be firmly connected to the grip part 51.
That is, the grip part 51 made of a rubber material is configured to overlap with an end of the silicon cap 73, thereby performing a waterproof function.
Meanwhile, when a key of the grip part 51 is operated, a power source of the battery 60 is supplied to LEDs 67, 68 via pogo pin 65 and via the FPCB 63 and a negative terminal 11 and a positive terminal 62 so that the corresponding LEDs can be turned on or off according to the operation of the key.
Here, the LED 67 and LED 68 are installed to be opposite to each other so that the LED 67 can serve a head lamp 5, and the LED 68 can serve as a brake lamp.
Furthermore, by turning on or off of other LEDs arranged around the LEDs 67, 68, the other LEDs serve as the turn indicator 56 so as to display a direction upon riding of the bicycle.
