Description

{SAFETY BRAKING APPARATUS FOR BICYCLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a safety brake device for a bicycle, and more particularly, to a safety brake device for a bicycle which induces an electrical connection by means of a brake wire pulled at the time of brake operation so that the brake lamp is mechanically simple, To a safety brake device for a bicycle which can easily adjust the position of a terminal for energization.

A bicycle is a type of motorcycle that rotates a wheel by the power of a person. The bicycle is designed to transmit the stepping force to the rear wheel through a pedal, a crank mechanism, and a chain.

These bikes have a manual braking system that operates independently on the front and rear wheels, with the front wheels steering, the rear wheels driving, the crank mechanism turning the torso's foot force into rotational force, The frame is a pipe connected with the shape of two triangles combined, and the pipe is made of low carbon steel pipe or high tensile steel pipe having an outer diameter of 25.4 to 28.6 mm and a thickness of 1 to 1.4 mm. In the case of special steel pipes, the steel pipe is formed by pressing a thin and light material having a thickness of 0.4 to 1.0 mm, or it is inserted into a connection portion made of a malleable cast iron, and is made of brass welding or brazing. Alternatively, the frame may be formed by directly welding only the pipe at low temperature or by die-casting without using a connecting portion. In either case, cover with a waterproof coating. The length of the vertical pipe section where the saddle is installed is called the frame dimension and indicates the size of the bicycle. It is important to select a frame of suitable size for the leg length of the fighter. Usually 26 or 24 is called the outside diameter of the wheel in inches. The front fork is able to turn left and right through the ball bearing in the top and bottom of the head pipe and is bent according to the type of the vehicle. The stability and steering characteristics of the vehicle depend on the value of the bending, the inclination angle (castellation angle) with respect to the road surface of the head pipe, and the restoring force of the front tire. The front wheel is supported between the two legs of the front fork. In the center of the wheel there is a hub with left and right bearings called cup and cone type.

Further, the rear light emitted by the electric force can not be installed on the bicycle due to complicated wiring and circuitry.

The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

The taillight is proposed in the domestic public utility model 20-2010-0011620 (design name: tail lamp).

1 to 6, in a safety brake device 100 for a bicycle 10 according to the first embodiment of the present invention, when a brake 70 is operated, a brake light emitting element 134 as a tail lamp is turned on It is a facility to prevent collision.

The safety brake apparatus 100 includes a fixing member 110, a movable member 120, a brake lamp unit 130, and a brake light emission induction unit 140.

Particularly, the bicycle 10 forms an outer shape with the frame 20 and has a handle 30 on the front side of the frame 20. The handle 30 is provided on both sides of the front side of the frame 20 and has a lever body 50 on either side or both sides thereof.

The lever body (50) hinges the brake lever (60).

In addition, the brake 70 is provided on the frame 20 corresponding to at least one of the front wheel 42 and the rear wheel 44. Thus, when the brake lever 60 is operated, the brake wire 110 is pulled toward the brake lever 60, so that the brake 70 brakes the front wheel 42 or the rear wheel 44.

When the brake lever 110 is exposed to the outside, when the brake lever 110 is axially moved by the operation of the brake lever 60, it may damage the user's body such as abrasion. Thus, the brake wire 110 is wrapped around the shell member 120. That is, the sheath member 120 inserts and protects the brake wire 110.

In addition, the sheath member 120 is fixed between the brake 70 and the brake lever 60. Accordingly, the brake wire 110 is reciprocated in the axial direction with respect to the jacket member 120 which is positionally fixed in accordance with the operation of the brake lever 60.

By way of example, the brake 70 includes a first brake arm 82 and a second brake arm 84.

The first brake arm 82 is hinged to the frame 20 at one side with respect to the front wheel 42 or at one side with respect to the rear wheel 44. The first brake arm 82 is pivoted on the basis of the hinge portion with the frame 20 and has a first brake pad 83 for braking the front wheel 42 or the rear wheel 44. The first brake arm 82 and the first brake pad 83 are applicable in various shapes and various materials.

The second brake arm 84 is hinged to the frame 20 at one side with respect to the front wheel 42 or at the other side with respect to the rear wheel 44. The second brake arm 84 is pivoted on the basis of the hinge portion with the frame 20 and has a second brake pad 85 for braking the front wheel 42 or the rear wheel 44. The second brake arm 84 and the second brake pad 85 are applicable in various shapes and various materials.

Of course, the first brake arm 82 and the second brake arm 84 may be applied to the front wheel 42 and the rear wheel 44 at the same time.

One side of the cover member 92 is fixed to the lever body 50 and the other side is fixed to the first brake arm 82 side. One end of the brake wire 90 is connected to the brake lever 60 and the other end is connected to the second brake arm 84 through the first brake arm 82. [

When the user pulls the brake lever 60, the brake wire 90 pulls the second brake arm 84 so that the second brake pad 85 abuts against the other side of the front wheel 42 or the rear wheel 44 Braking. The brake wire 90 rotates the first brake arm 82 toward the second brake arm 84 so that the first brake pad 83 contacts one side of the front wheel 42 or the rear wheel 44 Braking.

On the other hand, the brake lamp unit 130 is operated to emit light by an external operation. At this time, the brake lamp unit 130 is installed on at least one of the front side and the rear side of the frame 20.

The fixed member 110, the movable member 120 and the braking light emitting induction unit 140 are connected to the braking light emitting element 130 included in the brake lamp unit 130 through the pulling of the brake wire 110 with respect to the covering member 120 134). That is, when the user pulls the brake lever 60, the brake light emission inducing unit 200 is operated to emit light to display the braking state.

Particularly, the brake lamp unit 130 includes a casing 132, an intermittent light emitting element 133, a power supply unit 136, and an intermittent switch 138.

The casing 132 accommodates and protects the intermittent light emitting device 133, the power supply unit 136, and the like. Of course, the casing 132 can be deformed into various shapes.

The intermittent light emitting element 133 is emitted by an external operation, and can be variously applied to a lamp, an LED, and the like. The number of the intermittent light emitting elements 133 is not limited. Of course, the intermittent light emitting element 133 is fixedly mounted inside the casing 132 in various ways.

Also, the power supply unit 136 serves to supply power to the intermittent light emitting element 133. At this time, the power supply unit 136 is mounted on the casing 132 and is electrically connected to the intermittent light emitting device 133. The power supply unit 136 is applicable as a replaceable battery.

In addition, the intermittent switch 138 serves to supply power of the power supply unit 136 to the intermittent light emitting element 133. Thus, when the intermittent switch 138 is turned ON, the power of the power supply unit 136 is supplied to the intermittent light emitting element 133. [ As a result, the intermittent light emitting element 133 is maintained in a lighted state.

Conversely, when the intermittent switch 138 is turned off, the power supply of the power supply 136 is released to the intermittent light emitting element 133. As a result, the intermittent light emitting element 133 maintains the extinguished state.

The intermittent light emitting element 133 serves as a tail lamp or a fog light. Particularly, the intermittent switch 138 is fixedly installed at various positions such as the handle 30, the frame 20, or the casing 132.

The fixing member 110 is located between the first brake arm 82 and the second brake arm 84 that are spaced apart or away from each other when the brake lever 60 is operated to face the brake lever 90, And is held at the end of the envelope member 92 and fixed in position.

In particular, the fixing member 110 penetrates the first through hole 116 to axially insert the brake wire 90. At this time, the first through hole 116 is sized to be freely movable in the axial direction by an external force pulled by the brake wire 90.

The movable member 120 is fixed to the brake wire 90 located between the first brake arm 82 and the second brake arm 84 and exposed in the axial direction of the shell member 92. [ In addition, the movable member 120 is moved to the fixed member 110 side together with the brake wire 90 pulled.

In particular, the movable member 120 penetrates the second through hole 126 to axially insert the brake wire 90. At this time, the second through hole 126 is sized to be freely movable in the axial direction by an external force pulled by the brake wire 90.

In addition, the fixing member 110 is formed in a cylindrical shape to form a space therein. Then, the movable member 120 moves together with the brake wire 90 and enters and exits the fixing member 110.

That is, one side of the fixing member 110 is closed in the axial direction, and the other side is opened to allow the moving member 120 to pass through. The first through hole 116 is formed on one side of the fixing member 110.

The movable member 120 may be formed into a sleeve or a rod shape which enters and exits the fixing member 110.

Further, the fixing member 110 can be fixed in various ways.

As an example, the fixing member 110 extends the socket 112 at one side so as to wrap and fix the enclosure member 92. The socket member 112 receives the end portion of the sheath member 92 on the first brake arm 82 side so that the fixing member 110 is prevented from moving toward the first brake arm 82 side.

At this time, the socket 112 can be deformed into various shapes and can be integrally manufactured in the fixing member 110.

Then, the socket 112 is detached from the outer shell member 92 by forcibly inserting the outer shell member 92 and pressing the outer shell member 92.

In addition, the movable member 120 can be engaged with the brake wire 90 by various methods.

By way of example, the shifting member 120 may be bound to the brake wire 90 by the binding member 122 and moved together. Here, the binding member 122 may be variously applied to a bolt, a screw, a pin, and a key for binding the moving member 120 and the brake wire 90. For convenience, the binding member 122 is shown as a bolt.

On the other hand, the braking light-emitting induction unit 140 serves to induce the light emission of the brake light emitting element 134 by inducing the energization when the movable member 120 is moved by the set distance by the brake wire 90.

The braking light emitting induction unit 140 includes a high-voltage electron gun 142, a moving barrel electron 144, and a power supply unit 136.

The stationary electron 142 is connected to the fixing member 110 and is made of a conductor. At this time, the fixed-base electrons 142 can be variously applied to the electromagnet or the connection terminal and can be formed in various ways. In addition, the fixed-type electron 142 is supplied with power from the power supply unit 136.

The movable barrel electrons 144 are then connected to the movable member 120 so as to face the fixed-electrode electrons 142 and contact the fixed-electrode electrons 142 when the brake wire 90 is pulled. At this time, the moving cylinder magnet 144 can be variously applied to the electromagnet or connection terminal, and can be formed in various ways. In addition, the moving barrel electrons 144 serve to form a closed loop to electrically connect the power supply 136 and the brake light emitting device 134 in contact with the high-

Particularly, when the user pulls the brake lever 60, the brake wire 90 is pulled toward the brake lever 60, and in conjunction therewith, the moving barrel electrons 144 are contacted with the high-tension electrons 142.

When the user pulls the pulled brake lever 60, the brake wire 90 is moved in the opposite direction and returns to the initial state. Thus, the moving barrel electrons 144 are brought into contact with the electronically steerable electrons 142.

The power supply unit 136 serves to supply power to induce the light emission of the brake light emitting element 134 of the brake lamp unit 130 when the fixed-to-electric electrons 142 and the moving tube 144 contact each other. Here, the power supply unit 136 for supplying power to cause the brake light emitting device 134 to emit light and the power supply unit 136 for supplying power to emit the mode light emitting device 133 may be different from each other.

The brake light emitting element 134 is fixed inside the casing 132. The number of the brake light emitting elements 134 is not limited.

Accordingly, the brake lamp unit 130 includes a casing 132, an intermittent light emitting element 133, a brake light emitting element 134, a power supply unit 136, and an intermittent switch 138.

On the other hand, when the user releases the brake lever 60 pulled, the brake wire 9 is moved to the initial position, and the moving member 120 is also moved to the initial position.

Thus, the movable member 120 is moved to the initial position with respect to the fixed member 110 by the elastic return member 170 when the pulling force of the brake wire 90 is removed.

That is, one side of the elastic return member 170 is elastically supported on the inner side of the fixing member 110, and the other side is elastically supported on the moving member 120. The resilient return member 170 applies a force to push the movable member 120 against the fixed member 110. [ Here, the elastic return member 170 is a coil spring.

In particular, the elastic return member 170 may be installed to prevent exposure to the outside of the tubular fixing member 110. That is, the elastic return member 170 is inserted into the fixing member 110 so that one side is elastically supported inside the fixing member 110. Then, the movable member 120 protrudes and forms a locking projection 172 on the circumferential surface. Thus, the other side of the elastic return member 170 is elastically supported by the locking projection 172. Of course, the stopper portion 172 can be applied in various shapes.

On the other hand, the high-electric-current electrons 142 can be fixed to one side of the interior of the fixing member 110 so as not to interfere with the brake wire 90 pulled, and the break wire 90 It can be fixed at the end of the movable member 120 so as not to interfere.

In this case, when the moving barrel electron 144 hits the high-mobility electron 142 or the pressing force of pushing the high-mobility electron 142 is too great, the high-electron beam 142 or the moving barrel electron 144 It can be broken.

In addition, it is troublesome to adjust the distance between the solid-state electron 142 and the moving barrel electrons 144.

Thus, the fixed-base electrons 142 are provided in the fixed supporter 150. The fixed supporter 150 is made of an insulating material, and may be formed in various shapes, and fixes the fixed-type electron 142 in various ways.

The fixed supporter 150 can be buffered and supported by the fixing buffer member 152 on the inner surface of the fixing member 110.

Thus, when the moving barrel electrons 144 continue to move even after contact with the high-conserving electron 142, the fixed buffer member 152 is compressed and serves as a buffer.

Here, the fixing buffer member 152 is a coil spring. One side of the fixing buffer member 152 is elastically supported on one side of the fixing member 110, and the other side is elastically supported on the fixing supporter 150.

In addition, the inner side of the fixing member 110 and the fixed supporter 150 may extend the first rib 154 to prevent the fixing buffer member 152 from being bent in the lateral direction during compression. Of course, the first rib 154 can be deformed into various shapes.

7, the safety brake apparatus 100 for a bicycle according to the second embodiment of the present invention includes a fixing member 110, a moving member 120, a brake lamp unit 130, and a brake light induction unit 140 ).

The brake lamp unit 130 and the brake light emission induction unit 140 are replaced with the above.

The fixing member 110 is made of an insulating material, is fixed in position, and has a sleeve or a rod shape.

In addition, the moving member 120 is made of an insulating material and has a tubular shape that opens toward the fixing member 110 side.

Thus, the movable member 120 is moved along the axial direction of the fixed member 110 to receive the fixed member 110 therein.

Further, the fixing member 110 can be fixed in various ways.

As an example, the fixing member 110 extends the socket 112 on one side. The socket (112) recesses the stopping groove (118). In particular, the stopping groove 118 is recessed along the edge of the first through hole 116. The stopping groove 118 of the socket 112 serves to detain the enclosure member 92. Thus, the fixing member 110 can be fixed in position.

Then, the socket 112 can be brought into close contact with the circumferential surface of the envelope member 92 by the crimping member 114. The crimping member 114 can be applied as a nut. Thus, the socket 112 and the fixing member 110 are screwed with the crimping member 114. [

The crimping member 114 is rotated on the circumferential surface of the fixing member 110 and is moved to the socket 112 and is held in the socket 112 112).

On the other hand, the moving member 120 is bound to the brake wire 90 by the binding member 122 and moved together.

Here, the binding member 122 includes a connecting rod 123 and a clip 125.

The connecting rod 123 is constrained to the movable member 120. That is, the connecting rod 123 is constrained to the second through hole 126. Thus, the brake wire 90 is inserted into the connecting rod 123. Of course, the connecting rod 123 may be formed in various shapes and may be fastened to the movable member 120. [

The clip 125 serves to couple the connecting rod 123 to the brake wire 90. The clip 125 is variously applicable, showing the function of clamping the connecting rod 123. Accordingly, the connecting rod 123 can be brought into close contact with the brake wire 90 and moved together with the brake wire 90. Of course, the connecting rod 123 can be bound to the brake wire 90 in various ways.

Further, the distance between the fixed-body electron 142 and the moving cylinder electrons 144 can be cumbersome.

Thus, the moving barrel electrons 144 are provided in the mobile supporter 160. The mobile supporter 160 is made of an insulating material and can be formed in various shapes and fixes the moving tube magnet 144 in various ways.

The movable supporter 160 can be buffered and supported by the moving buffer member 162 on the inner side of the movable member 120. [

Thus, when the moving barrel electrons 144 continue to move even after contact with the high-electron-emitting electrons 142, the moving buffer member 162 is compressed and serves as a buffer.

Here, the movement buffering member 162 is a coil spring. One side of the moving buffer member 162 is elastically supported on the movable supporter 160 and the other side is resiliently supported on the other side of the moving member 120.

In addition, the other inner side of the movable member 120 and the movable supporter 160 may extend the second rib 164 to prevent the movable buffer member 162 from being bent in the lateral direction during compression. Of course, the second rib 164 can be deformed into various shapes.

The reference numerals not described are replaced with those described above.

8, the safety brake apparatus 100 for a bicycle according to the third embodiment of the present invention includes a fixing member 110, a moving member 120, a brake lamp unit 130, and a brake light emission induction unit 140 ).

The fixing member 110, the shifting member 120, the brake lamp unit 130, and the brake light emission induction unit 140 are replaced with those described above.

The movable member 120 may include a distance adjusting member 180 so as to adjust the distance of the moving barrel electrons 144 relative to the fixed-

At this time, the distance adjusting member 180 is restrained to the moving member 120. That is, the distance adjusting member 180 is constrained to the second through hole 126 of the moving member 120, and the brake wire 90 is inserted and fixed.

Further, the distance adjusting member 180 has the moving barrel electrons 144. The distance adjusting member 180 can be moved axially with respect to the moving member 120 by screwing or the like with the moving member 120. [ As a result, the movable barrel electrons 144 can be distanced from the high-electron beam 142.

In particular, the distance adjustment member 180 can be engaged with the brake wire 90 in various ways.

The reference numerals not described are replaced with those described above.
