Bicycle brake device according to an embodiment of the present invention by using a separate lock key in the brake device is in operation to maintain the brake operating state as it is, even without a separate locking device to restrain the rotation of the bicycle As a device capable of preventing theft, the device 100 includes a case 100, first and second pivotal links 210 and 220, an operation plate 300, and a locking module 400.

Case 100 is fixedly mounted to the bicycle frame, the receiving space is formed therein to form the overall appearance of the bicycle brake device. The case 100 may be separated into a case cover 110 and a case body 120, and the case cover 110 and the case body 120 may be coupled by a separate closing cover 130.

The first and second pivotal links 210 and 220 are symmetrically mounted to the case 100, and at one end, the brake pads 230 are coupled to each other, and the brake pads 230 are pressed against or released from the bicycle wheels 10. It is mounted to be rotatable in the direction. The first and second pivotal links 210 and 220 are elastically rotatably supported in a direction in which the brake pad 230 is released from the bicycle wheel 10 by a separate elastic member 203 provided in the case 100. It is composed.

The operation plate 300 is mounted in the case 100 so as to linearly move in association with rotational movements of the first and second rotational links 210 and 220, and one end of the brake wire W is connected thereto. Therefore, when the user operates the brake lever (not shown), the brake wire W is towed by the brake lever, and the actuation plate 300 is moved in the first direction (FIGS. 1 to FIG. 1) by the pulling force of the brake wire W. FIG. It moves linearly in the upward direction based on the direction shown in FIG.

The actuation plate 300 and the first and second pivotal links 210 and 220 are configured to interlock with each other. For this purpose, the actuation plate 300 is disposed between the first and second pivotal links 210 and 220 so as to move downward. The inclined surface 301 is formed on both sides in the form of increasing width, and the other ends of the first and second pivotal links 210 and 220 are in rolling contact with the inclined surface 301 of the operation plate 300 on opposite inner surfaces. The guide roller 204 may be mounted.

According to this interlocking structure, when the operation plate 300 moves up and down linearly, the first and second pivotal links 210 and 220 are in rolling contact with the guide roller 204 along the inclined surface 301 of the operation plate 300 and the rotating shaft ( 201) to move around the rotation.

More specifically, the first and second pivotal links 210 and 220 in the first upward movement of the operating plate 300 is linked to the direction in which the brake pad 230 is in pressure contact with the bicycle wheel 10 (brake operating direction Rotate with). In addition, the first and second pivotal links 210 and 220 may receive elastic force in a direction in which the brake pad 230 is released from the rotating wheel 10 by the elastic force of the elastic member 203 (brake release direction). When the first and second rotational links 210 and 220 rotate in the brake release direction by the elastic force, the operation plate 300 moves in the second direction (downward direction) opposite to the first direction in association with the first and second rotational links 210 and 220.

That is, as shown in FIG. 3, the first and second pivotal links 210 and 220 are elastically rotatably supported in the brake release direction by the elastic member 203, so that the brake is maintained in the deactivated state. When the brake lever is pulled, as shown in FIG. 4, a traction force is generated for the brake wire W so that the operation plate 300 moves upward in the first direction, and the first and second pivotal links 210 and 220 are linked thereto. Moves in the direction of brake operation. Thereafter, when the user releases the brake lever, the traction force on the brake wire W disappears, so that the first and second pivotal links 210 and 220 rotate in the brake release direction again by elastic force, and interlock with the operation plate 300. ) Moves downward in the second direction and returns to its normal state.

In the above description, the operating plate 300 and the first and second pivotal links 210 and 220 are interlocked with each other in a rolling contact by the guide roller 204. However, the operation plate 300 and the first and second pivotal links are interlocked. The interlocking structure of the links 210 and 220 may be variously configured using various machine elements.

For example, a plurality of connection links (not shown) may be mounted to connect the lower ends of the operation plate 300 and the first and second rotational links 210 and 220, and when the operation plate 300 is linearly moved in one direction. The first and second pivotal links 210 and 220 may be configured to interlock in a manner in which they rotate in opposite directions by the connection links.

The locking module 400 is operated through a separate locking key (not shown) to fix or release the operation plate 300 while the operation plate 300 is moved upward in the first direction.

In this case, the locking module 400 includes a lock body 410 disposed in the inner space of the case 100 and rotatably moved to a lock mode or a release mode state by manipulation of the lock key, and the lock body 410 is locked. It is configured to support the operation plate 300 is fixedly fixed in the first direction of movement in the state rotated in the mode.

According to this configuration, the bicycle brake apparatus according to the embodiment of the present invention can fix the position of the operation plate 300 to the first upward movement state through the locking module 400 operated by the locking key, so that the user brakes. Release the lever to keep the brakes in operation. Therefore, it is possible to simply operate the locking module 400 in the lock mode without a separate locking device such as a lock, thereby making it impossible to drive the bicycle, thereby preventing theft of the bicycle.

In particular, the locking module 400 according to one embodiment of the present invention is configured to rotationally restrain the first and second pivotal links 210 and 220 interlocked by fixing the operation plate 300 to position the brake wire. Even when cutting, the rotation restraint state of the first and second pivotal links 210 and 220 is maintained as it is, and thus the bicycle brake operation state is not released. Accordingly, a separate tool such as a cutter is used except for stealing by carrying the bicycle itself. Even though you can't steal your bike easily, you can prevent theft of the bike more completely.

In addition, in the case of a general bicycle lock device, a ring-shaped lock structure for fixing the bicycle frame to a separate fixed structure is also applied. In this case, the bicycle is fixed to the fixed structure by the locking device to prevent the transport of the bicycle itself. In this locking structure, theft accidents such as disassembling and stealing only bicycle wheels have occurred. Locking module 400 according to an embodiment of the present invention is locked because the first and second pivotal links 210 and 220 are rotationally restrained in a brake operating state, that is, the brake pad 230 is in pressure contact with a bicycle wheel. Since the bicycle wheels are restrained by the brake device unless the module 400 is changed to the release mode, it is also possible to prevent theft accidents that steal only the bicycle wheels separately.

In addition, even if a large and heavy separate locking device is not carried, only the locking key can be used to safely lock and restrain the bicycle through the locking module 400 so that the bicycle can be used more conveniently.

Next, look at the configuration of the lock module 400 in more detail.

The lock module 400 includes the lock body 410 as described above, in addition to the key bundle 420 and the key bundle coupled to the case 100 to operate in the lock mode or the unlock mode by the operation of the lock key. The rotary rod 421 is coupled to the 420 and rotates about a longitudinal axis in a locked mode or a released mode state according to the operating state of the key bundle 420.

At this time, the locking body 410 is coupled to the rotary rod 421 to rotate integrally with the rotary rod 421, in a manner that one end is engaged with one side of the operation plate 300 in the state rotated in the lock mode. The operation plate 300 can be fixedly supported.

That is, in the state in which the locking body 410 is rotated to the release mode by the lock key, as shown in FIGS. 3 and 4, the actuation and release of the brake are performed in the same manner as described above according to the operation of the brake lever. When the brake is operated by pulling the brake lever as shown in FIG. 4, the lock module 400 is rotated in the lock mode by operating the lock key as shown in FIG. 5. Is rotated in the lock mode to securely support one side of the operation plate (300). As a result, since the operation plate 300 is fixed in the state of being moved upward in the first direction, the first and second pivotal links 210 and 220 are maintained in a state of being rotated in the brake operation direction and the brake operation state is kept as it is. . In this case, a separate support protrusion 320 may be formed on one side of the operation plate 300 so as to be engaged with the locking body 410.

On the other hand, the lock body 410 has a slot hole 411 is formed long in one direction so as to penetrate through the rotation rod 421 in the center. Through the slot hole 411 it is possible to adjust the through coupling position with respect to the rotation rod 421 of the lock body 410. That is, as shown in (a) of FIG. 6, the length from the rotation rod 421 to the end of the locking body 410 is combined by X, or as shown in (b) of FIG. 6, the slot hole ( By adjusting the coupling position of the lock body 410 through the 411 may be coupled so that the length from the rotation rod 421 to the end of the lock body 410 by Y. Thus, by adjusting the length from the rotary rod 421 to the end of the locking body 410, it is possible to adjust the fixed support position of the operating plate 300, according to the rim 11 of different thickness for each bicycle wheel Also, all brake locks can be applied stably. The bicycle wheel 10 is generally formed of a rim 11 in a circular frame shape and a portion of the tire 12 coupled to the outside thereof, and the brake pad 230 of the brake device is the rim 11 of the bicycle wheel 10. Rotationally restrains the part in pressure contact.

For example, when the length from the rotating rod 421 to the end of the locking body 410 is combined as long as Y, as shown in FIG. 6 (b), the operation plate 300 is locked in FIG. 6. Since the position is fixed at a relatively upwardly moved point as compared with (a) of, the rotational movement distance of the first and second pivotal links 210 and 220 is further increased, so that the thickness of the rim 11 is thinner. The brake lock state can be applied to the wheel 10.

In addition, the lock body 410 is formed with a first inclined surface 413, one surface of which the rotating rod 421 penetrates by a predetermined angle, the locking module 400 is coupled to the rotating rod 421 through the locking body And a locking block 430 having a second inclined surface 431 corresponding to the first inclined surface 413 of 410, wherein the locking body 410 and the locking block 430 are formed of the first inclined surface 413. The second inclined surface 431 may be coupled to face contact with each other.

According to this structure, when the locking block 430 is pressed or released by the lock body 410 through a separate pressure cover 440, the lock block 430 and the lock by the inclined surface contact of the lock body 410 The body 410 moves in a direction perpendicular to the pressing direction (up or down direction). Therefore, length adjustment from the rotary rod 421 to the end of the locking body 410 may be performed through pressure adjustment through the pressure cover 440. At this time, the outer circumferential surface of the rotary rod 421 and the inner circumferential surface of the pressure cover 440 may be formed with a screw thread that can be fastened to each other, the pressure cover 440 may be coupled to the rotary rod 421 in a screwing manner.

On the other hand, the brake pads 230 which are mounted at one end of the first and second pivotal links 210 and 220 and are in pressure contact with the wheels 10 are subject to abrasion according to prolonged use. When wear occurs in the brake pad 230 as described above, the thickness of the brake pad 230 becomes thin. In general, when the thickness of the brake pad 230 becomes thin, the user operates the brake lever more strongly to increase the rotational movement angle of the first and second pivotal links 210 and 220, thereby generating the same brake braking force. With regard to the general brake braking function, wear of the brake pad 230 is not a problem in use.

However, in the brake device according to the embodiment of the present invention, the brake lock state is maintained while the brake pad 230 is in pressure contact with the wheel 10, and the first and second pivotal links are operated when the brake pad 230 is operated in the locked state. The interval of the brake pads 230 mounted on the 210 and 220 is determined according to the positioning state of the locking module 400. That is, as described above, the distance between the brake pads 230 is determined according to the engagement position of the locking body 410.

Therefore, in order to stabilize the brake lock function when the brake pad 230 is worn out, the position of the lock body 410 must be adjusted by adjusting the pressure of the lock block 430. That is, the position of the locking body 410 should be adjusted so that the length from the rotating rod 421 to the end of the locking body 410 is made longer in response to the amount of wear of the brake pad 230. In this case, it may be cumbersome to check the amount of wear of the brake pad 230 and adjust the position of the locking body 410 each time.

Brake device according to an embodiment of the present invention is provided with a separate pressing means 500 to solve this trouble and to always maintain a stable lock state even if wear occurs in the brake pad 230, pressing means The configuration for 500 is shown in FIGS. 7-9.

The pressurizing means 500 is a brake pad 230 is a bicycle wheel when the bicycle wheel 10 is rotated in a state in which the brake pad 230 is pressed against the bicycle wheel 10 by the locking operation of the locking module 400. It is formed to press the brake pad 230 so as to be in close contact with the (10).

That is, when a certain amount of wear occurs in the brake pad 230, the close contact state of the brake pad 230 with respect to the bicycle wheel 10 in the locked state through the locking module 400 is relatively weakened, thereby reducing the frictional resistance. Therefore, in this state, the bicycle wheel 10 may be strongly rotated to pull the bicycle. The pressurizing means 500 according to an embodiment of the present invention is configured to press the brake pads 230 more closely to the rotating wheels 10 when the rotational movement of the bicycle wheels 10 occurs in the locked state. Therefore, when dragging the bicycle due to a decrease in frictional resistance due to wear of the brake pad 230, the brake pad 230 is brought into close contact with the bicycle wheel 10 by the pressurizing means 500, thereby increasing the frictional force. The rotation of the bicycle wheel 10 can be prevented.

The pressing means 500 passes through the inclined coupling hole 510 and the inclined coupling hole 510 formed at the end of the first and second pivotal links 210 and 220 as shown in FIGS. 7 and 8. The adapter 520 is inserted and includes an adapter 520 coupled to the brake pad 230 on one side, and the inclined coupling hole 510 has an inner diameter extending toward the end at an end portion adjacent to the bicycle wheel 10 of the inclined coupling hole 510. 515 is formed, and an adapter inclined surface 523 corresponding to the coupling hole inclined surface 515 is formed at an end portion adjacent to the bicycle wheel 10 of the adapter 520 so as to contact the coupling hole inclined surface 515.

At this time, the inner surface of the inclined coupling hole 510 is formed to have upper and lower surfaces 511 and 512 parallel to each other, and both side surfaces 513 and 514 parallel to each other, and the coupling hole inclined surface 515 at the end portions of both side surfaces 513 and 514 parallel to each other. Is formed.

The adapter 520 has an adapter sleeve having a top and bottom contact with the top and bottom surfaces 511 and 512 of the inclined coupling hole 510 and inserted into the inclined coupling hole 510 so that both sides thereof are spaced apart from both sides 513 and 514 of the inclined coupling hole 510. 521, and an inclined extension 522 that extends inclined from both end portions of the adapter sleeve 521 and is formed with the adapter inclined surface 523.

At this time, the brake pad 230 is coupled to the end of the inclined expansion portion 522 of the adapter 520, the adapter 520 is the adapter inclined surface 523 is the coupling hole inclined surface 515 of the inclined coupling hole 510 Inserted into contact.

In addition, the adapter 520 has a through coupling hole 501 is formed in the center, the coupling bolt 530 is inserted through the through coupling hole 501 is fastened to the brake pad 230, the brake in this way Pad 230 is coupled to adapter 520.

According to this structure, when the bicycle wheel 10 rotates while the brake pad 230 is in contact with the bicycle wheel 10, the brake pad 230 may be in contact with the bicycle wheel 10 by a frictional force with the bicycle wheel 10. In addition, the adapter 520 moves in a direction adjacent to the bicycle wheel 10 by the coupling hole inclined surface 515 and the adapter inclined surface 523 during the movement of the brake pad 230, and the brake pad 230. Moves in a direction adjacent to the bicycle wheel 10 with the adapter 520.

In more detail, as shown in FIG. 9A, the adapter inclined surface 523 of the adapter 520 is normally coupled to the inclined coupling hole 510 formed in the first and second pivotal links 210 and 220. The inclined surface 515 is positioned in contact with each other, and the first and second pivotal links 210 and 220 rotate when the locking module 400 is locked to press each brake pad 230 to the bicycle wheel 10. It remains in contact.

In such a locked state, when the bicycle wheel 10 is rotated to pull the bicycle as shown in FIG. 9B, the brake pad 230 may cause the bicycle wheel to be damaged by friction with the bicycle wheel 10. 10) together with the bicycle wheel 10 to move finely along the rotational movement direction. The lower side is moved based on the direction shown in FIG. 9. In this process, since the adapter inclined surface 523 is moved along the coupling hole inclined surface 515, the adapter 520 is simultaneously moved to the bicycle wheel 10 side. It moves to the right with respect to the direction shown in FIG. That is, when the bicycle wheel 10 moves in rotation while the brake pad 230 is in pressure contact with the bicycle wheel 10 according to the locking operation of the locking module 400, the adapter 520 may have an adapter inclined surface 523. ) And the coupling hole inclined surface 515 simultaneously move by X1 in the direction of movement of the bicycle wheel 10 and X2 in the direction close to the bicycle wheel 10. At this time, since the brake pad 230 also moves integrally with the adapter 520, the brake pad 230 moves by X2 in a direction close to the bicycle wheel 10. Therefore, since the brake pad 230 presses the bicycle wheel 10 in close contact with the movement distance X2 of the brake pad 230, the rotational movement with respect to the bicycle wheel 10 can be prevented.

In FIG. 9C, the rotational movement direction of the bicycle wheel 10 is opposite to that of FIG. 9B, and in this case, the adapter 520 and the brake pad 230 may use the bicycle wheel 10. X2 in the direction close to the), since the bicycle wheel 10 is pressed more closely, it is possible to prevent the rotational movement with respect to the bicycle wheel (10).

According to such a structure, even if the user does not adjust the setting position of the locking module 410 when the brake pad 230 is worn, the brake pad 230 is moved to the bicycle wheel 10 when the bicycle wheel 10 is moved in the locked state. Since the contact is more closely contacted, the user can use it more conveniently without frequent setting position adjustment of the locking module 400, and the locking function by the brake pad 230 is always kept stable and can be used more safely.

A through engagement portion 150 into which the protrusion 250 can be inserted is formed.

At this time, the coupling protrusion 250 is not detachable in the direction of being released from the through engagement portion 150 as it rotates together with the first and second pivotal links 210 and 220 in a state of being inserted through the through engagement portion 150. To be engaged.

More specifically, the coupling protrusion 250 includes a circular section 251 having an outer circumference forming a circumferential surface and an engaging protrusion 252 protruding in a radial direction at the end of the outer circumferential surface of the circular section 251. It is configured by. The engagement protrusion 252 may be formed in the shape of a polygonal pillar as shown in FIGS. 11 and 12, or alternatively, may be formed in the form of a protrusion key in which only one side portion protrudes in a radial direction.

In addition, the through engagement portion 150 is configured to include a circular block 151 and a through block 151 in which a through hole 152 having a shape corresponding thereto is formed such that the engagement protrusion 252 is inserted therethrough. The through block 151 is spaced apart from the inner side surface of the case cover 110.

Therefore, as shown in FIG. 12A, the engagement protrusion 250 having the circular section 251 and the engagement protrusion 252 corresponds to the shape of the through hole 151 of the through engagement portion 150. Inserted in the arrangement state, and after insertion is engaged as the engaging protrusion 250 rotates about the rotational axis 201 together with the first and second pivotal links 210 and 220 as shown in (b) of FIG. Engagement of the protrusion 250 The protrusion 252 is engaged with the through hole 151 of the through block 150 to form a structure that cannot be separated.
