JP 2005-81952 A

  In the bicycle interlocking lock described in Patent Document 1, when the rear wheel lock is operated, the jumper that has popped out is returned to the inside of the rear wheel lock by the return spring. The operating path to be operated is on the same track, and the stroke of the interlocking wire operating path is shorter than the stroke of the punching operating path. For this reason, when the interlocking wire does not slide to the unlocked position due to freezing or the like, there is a possibility that, even though the handle is locked, the protruding pin jumps back into the rear wheel lock and the rear wheel rotates. .

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a bicycle interlocking lock that can prevent the wheels from rotating despite the fact that the handle is locked. .

In order to solve the above-described problem, a bicycle interlock lock according to the invention described in claim 1 includes a wheel lock that locks a wheel and a handle lock that locks the handle in conjunction with the wheel lock. An interlocking lock for the wheel, wherein the wheel lock is inserted between the spokes of the wheel when the wheel is locked, a return spring for moving the yoke in a direction to unlock the wheel, and An operation lever that moves the yoke in a direction that locks the wheel against the force of the return spring, and a wire fixing piece that is attached to one end of an interlocking wire that locks the handle lock. The wire fixing piece moving path along which the wire fixing piece moves, and the interlocking wire urges the wire fixing piece in a direction to release the lock of the handle lock. A spring for removal, a protrusion provided integrally with the yoke, the protrusion moves, a protrusion moving path that partially wraps with the wire fixing piece moving path, and formed on the wire fixing piece, and the protrusion is A direction in which the protrusion is pushed by the protrusion in the protrusion movement path that partially wraps with the wire fixing piece movement path when moving the protrusion movement path and being inserted between the spokes of the wheel. The wire fixing piece is formed on the wire fixing piece, and moves between the protrusion moving path and the wire fixing piece moving path. When the wire fixing piece does not move to a position where the handle is unlocked when being pulled out, it is located in the protrusion moving path and prevents the protrusion from moving by the return spring. Possess a per unit that, the said projections moving path, when the contact portion has passed through from the wire fixing piece moving path and the lap portion, further wherein the projection is moved the protrusion is disengaged from said contact portion An empty running path is formed that ensures a stroke through which the yoke moves out from between the spokes of the wheel .

  In the invention according to claim 1, when the operation lever of the wheel lock is operated at the time of locking, the yoke provided integrally with the operation lever moves in the direction of locking the wheel against the force of the return spring, A spring is inserted between the spokes of the wheel, and the rotation of the wheel is locked. Also, a wire fixing piece is attached to one end of the interlocking wire that locks the handle, and the wire fixing piece moving path along which the wire fixing piece moves is the same as the protrusion moving path along which the protrusion provided integrally with the yoke moves. The part is wrapped. When locking, the projection moves along the projection movement path with the movement of the yoke, and when the projection is inserted between the spokes of the wheel, the projection pushes the contact portion formed on the wire fixing piece, The wire fixing piece moves in the direction to lock the handle against the force of the release spring. The interlocking wire is operated by the movement of the wire fixing piece, and the handle is locked by the handle lock. For this reason, since the handle is locked by the handle lock after the bolt is inserted between the spokes of the wheel, the handle is not locked first in spite of the state that the wheel can rotate. .

  On the other hand, when releasing the lock, by removing the pinning restraint, the pin pulls out from between the wheel spokes by the action of the return spring, and the wheel lock is released. At the same time, the operation lever integrated with the yoke returns to its original position. Further, the wire fixing piece moves in the biasing direction by the action of the release spring, the interlocking wire also moves in the unlocking direction of the handle, and the handle lock unlocks the handle.

When the lock is released, the contact portion formed on the wire fixing piece passes through the straight path portion that overlaps the protrusion moving path and moves further on the wire fixing piece moving path, but the wire fixing piece locks the handle. If it does not move to the release position, the contact portion is positioned on the protrusion moving path and prevents the protrusion from moving by the return spring. By preventing the movement of the protrusions, the yoke is prevented from being pulled out between the spokes of the wheel. For this reason, while the handle is locked by the handle lock due to the occurrence of an abnormality in the interlocking wire or the wire fixing piece, the wheel cannot be turned because there is always a pinch between the spokes. That is, while the handle is locked due to the occurrence of an abnormality in the interlocking wire or the wire fixing piece, it is safe because the bicycle is not inadvertently started and falls.
In addition, when the contact part comes out of the part that overlaps the wire fixing piece movement path, the protrusion moves away from the contact part, and the protrusion moves further to secure the stroke where the projection comes out between the spokes of the wheel. An empty runway is formed. This makes it possible to unlock the handle by moving the wire fixing piece before the yoke is pulled out from between the spokes of the wheel. For this reason, it is possible to more reliably avoid the rotation of the wheel even though the handle is locked.

  According to a second aspect of the present invention, in the bicycle interlocking lock according to the first aspect, when the abutting portion is in a state of preventing the movement of the protrusion, the yoke moves between the spokes of the wheel, The rotation of the wheel is also prevented.

  According to the second aspect of the present invention, when the contact portion prevents the movement of the protrusion, the yoke moves between the spokes of the wheel, and the rotation of the wheel is also prevented. As a result, it is possible to avoid the wheels from rotating even though the handle is locked.

According to a third aspect of the present invention, in the bicycle interlocking lock according to the first or second aspect, the protrusion movement path is a guide path along the movement path of the yoke, and the wire fixing piece movement path. , said a protrusion moving path and some wrapped straight road, the the guide path, when the contact portion has passed through from the straight path that wraps and the protrusion moving path, the projection is disengaged from said contact portion moves The empty runway is formed.

  In the invention according to claim 3, the protrusion moving path is a guide path along the movement trajectory of the yoke, the wire fixing piece moving path is a straight path partially wrapped with the protrusion moving path, and the wire fixing piece hits. When the part goes out of the straight road that overlaps with the protrusion movement path, the protrusion moves away from the contact part, and the protrusion moves further on the empty road formed on the guide path, and the stroke through which the yoke is released from between the spokes of the wheel is secured. The This makes it possible to unlock the handle by moving the wire fixing piece before the yoke is pulled out from between the spokes of the wheel. For this reason, it is possible to more reliably avoid the rotation of the wheel even though the handle is locked.

  The invention according to claim 4 is the bicycle interlocking lock according to any one of claims 1 to 3, wherein the handle lock is operated when the interlocking wire is operated by the wire fixing piece. A wire receiver that swings when the other end of the interlocking wire contacts, a lock pin that slides in conjunction with the wire receiver and locks the handle, and a lock spring that biases the lock pin in the lock direction of the handle And a return spring for returning the wire receiver in a direction in which the handle is unlocked.

  In the invention according to claim 4, when the interlocking wire is operated, the other end of the interlocking wire comes into contact with the wire receiver to swing, and the lock pin slides in conjunction with the wire receiver, and the action of the lock spring The lock pin locks the handle. By providing the lock spring, even if the position of the lock pin and the lock groove of the handle are not coincident, if the handle is turned a little, the position of the lock pin and the lock groove will be matched and the lock pin will be fitted.

  Further, when the interlocking wire is operated in the unlocking direction of the handle, the wire receiver is returned in the unlocking direction of the handle by the action of the return spring. As a result, the lock pin slides in the reverse direction, and the handle is unlocked. For this reason, with a simple configuration, the handle can be locked or unlocked by operating the interlocking wire.

  According to a fifth aspect of the present invention, in the bicycle interlocking lock according to any one of the first to fourth aspects, a display mark is provided for notifying the lock state of the handle in conjunction with the wire receiver. It is assumed that

  In the fifth aspect of the present invention, a display mark for notifying the locked state of the handle is provided in conjunction with the wire receiver, so that it is easy to determine whether or not the handle is locked.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a side view showing a bicycle to which a bicycle interlocking lock according to an embodiment of the present invention is attached. As shown in FIG. 1, the bicycle interlock lock 4 includes a wheel lock 10 that locks the rear wheel 31 of the bicycle 2, and a handle lock 20 that interlocks with the wheel lock 10 and locks the handle 32 of the bicycle 2. ing. Further, the wheel lock 10 and the handle lock 20 are connected by an interlocking wire 12, and the interlocking wire 12 is partially bound to the frame 34 by an attachment piece 35.

  FIG. 2 is a partially exploded perspective view showing an optimum circle lock as the wheel lock 10 and shows an unlocked state. FIG. 3A is a partially exploded perspective view showing a locked state of the wheel lock 10. As shown in FIGS. 2 and 3-1, the wheel lock (circle lock) 10 is connected to the circle lock main body 18 with a link-shaped yoke 15 inserted between the spokes of the rear wheel 31 when the rear wheel 31 is locked. A return spring 19 for moving the yoke 15 in a direction for unlocking the rear wheel 31, and an operation lever 11 provided integrally with the yoke 15 for moving the yoke 15 in the direction for locking the rear wheel 31. Yes. The interlocking wire 12 is composed of an inner wire 12 </ b> A and an outer wire 12 </ b> B outside the inner wire 12 </ b> A, and the inner wire 12 </ b> A is pushed out in conjunction with the yoke 15.

  Further, the wheel lock (circle lock) 10 is returned as a wire fixing piece 16 to which one end portion of the inner wire 12A is fixed, and a release spring for moving the wire fixing piece 16 in a direction in which the handle lock 20 is unlocked. Rotation for releasing the lock of the rear wheel 31 by removing the restraint of the spring 13 and the guide piece 17A (see FIG. 7 and FIG. 11) for guiding the wire fixing piece 16 and the yoke 15 And an expression key 40 (see FIGS. 7 and 11).

  The operation lever 11 is connected to the yoke 15 and includes a cylindrical protrusion 11 </ b> A at a portion along the circumferential direction of the yoke 15, and the protrusion 11 </ b> A moves together with the yoke 15. As shown in FIG. 7B and the like, the circle lock body 18 is formed along the movement locus of the yoke 15 and has a protrusion movement path 50 formed of a curved guide hole into which the protrusion 11A is inserted to move. Is provided.

  As shown in FIGS. 3-2, 7 (B), 11 (B), etc., the wire fixing piece 16 is pushed by the protrusion 11A when the yoke 15 is moved in the direction in which the rear wheel 31 is locked. A protrusion 16A is provided as a contact portion for pushing out the inner wire 12A. The wire fixing piece 16 is formed with a fixing hole 16C for fixing one end portion (spherical portion) of the inner wire 12A of the inner wire 12A. The fixed piece guide member 17 is provided with a wire fixed piece moving path 52 for moving the wire fixed piece 16 for operating the inner wire 12A in the locking and unlocking directions of the handle lock 20 inside the guide piece 17A. Yes.

  The wire fixing piece moving path 52 is formed so as to partially wrap with the protruding moving path 50 on the end side in the locking direction of the rear wheel 31 in the protruding moving path 50. The wire fixing piece moving path 52 is a linear groove (straight path) that wraps on the lock side with the curved protrusion moving path 50. Thus, when the protrusion 11A moves on the protrusion moving path 50 in the direction in which the rear wheel 31 is locked, the protrusion 11A is pushed by the protrusion 11A on the end side in the locking direction of the rear wheel 31 on the protrusion moving path 50. 16A moves in the direction of pushing out the inner wire 12A (see arrow B in FIG. 7). The handle lock 20 is locked when the inner wire 12A is pushed out.

  Further, the wire fixing piece 16 is formed with a contact portion 16B that moves between the protrusion moving path 50 and the wire fixing piece moving path 52 on the side opposite to the locking direction of the inner wire 12A. As shown in FIG. 9 (B), the contact portion 16B is configured to fix the wire if the pin 15 does not move to the position where the handle 32 is unlocked when the pin 15 is pulled out from between the spokes of the rear wheel 31. It is located at a portion where the piece moving path 52 and the protrusion moving path 50 overlap and prevents the protrusion 11A from moving by the return spring 19. On the opposite side (lock release side) of the rear wheel 31 in the protrusion movement path 50 along which the protrusion 11A moves, the contact portion 16B comes out of the wrap portion and moves to the wire fixing piece movement path 52 alone, and then An idle running path 50 </ b> A that secures a stroke in which 15 is removed from between the spokes of the rear wheel 31 is formed.

  In the wheel lock (circle lock) 10, the protrusion 11 </ b> A is formed by forming the wire fixing piece moving path 52 on which the wire fixing piece 16 moves on the end side in the locking direction of the rear wheel 31 in the protrusion moving path 50. When moving the protrusion moving path 50, when the yoke 15 is inserted between the spokes of the rear wheel 31, the protrusion 11A pushes the protrusion 16A, and the wire fixing piece 16 moves (see FIG. 11B). Thus, the handle lock 20 is locked after the yoke 15 is inserted between the spokes of the rear wheel 31.

  Further, as shown in FIG. 9B, when the wire fixing piece 16 does not move to the position where the lock of the handle 32 is released, the contact portion 16B is positioned in the protrusion moving path 50 and the protrusion 11A by the return spring 19 is not moved. In order to prevent the movement, the crown 15 is prevented from coming out between the spokes of the rear wheel 31 until the handle 32 is unlocked. That is, after the wire fixing piece 16 moves on the wire fixing piece moving path 52 and the lock of the handle 32 is released, the protrusion 11A moves on the idle running path 50A of the protrusion moving path 50, so that the yoke 15 moves to the rear wheel 31. It is designed to come out from between the spokes.

  4 is a perspective view showing the handle lock 20, FIG. 5 is a partially exploded perspective view of the handle lock 20, and FIG. 6 is a partial cross-sectional view showing a locked state of the front face of the handle lock 20. 6A is a view of a cross section behind the interlocking wire 12 in the handle lock 20 of FIG. 5 as viewed from the front, and FIG. 6B is a cross section of a portion passing through the interlocking wire 12. FIG. 6C is a plan view showing the display mark of the handle lock 20.

  As shown in FIGS. 4 to 6, the handle lock 20 includes a wire receiver 21 that swings when the other end (the end opposite to the wheel lock 10) of the inner wire 12 </ b> A of the interlocking wire 12 abuts, A lock pin 22 that slides in conjunction with the wire receiver 21, a lock spring 24 that urges the lock pin 22 in the lock direction of the handle 32, and a return spring 23 that returns the wire receiver 21 in a direction to unlock the handle 32 The display mark 25 for displaying the locked state / unlocked state of the handle 32 and the cover 27 are provided.

  A protrusion 21 </ b> A formed on the rotating shaft of the wire receiver 21 is fitted in the groove 22 </ b> A of the lock pin 22. Further, the surface of the convex portion 21B opposite to the protrusion 21A is a display mark 25 for displaying whether the handle 32 is in the locked state or the unlocked state, and is displayed from the display window 27A of the cover 27 shown in FIG. A part of the mark 25 can be seen through. Further, the tip of the lock pin 22 is fitted into a lock groove 33 that rotates together with the handle. The handle lock body 26 and the outer wire 12B are connected via the adjustment screw 14.

  Next, based on FIGS. 1-11, the lock | rock and unlocking mechanism of the interlocking lock 4 for bicycles of this invention are demonstrated.

  First, when the bicycle interlocking lock 4 is locked, the operation lever 11 of the wheel lock (circle lock) 10 is operated to lock the bicycle interlocking lock 4. That is, as shown in FIG. 2, the operation lever 11 is pushed down in the figure (in the direction of arrow A). Then, the return spring 19 extends, the operation lever 11 moves along the guide groove 18A of the circle lock body 18, and the ring-shaped yoke 15 pops out from the circle lock body 18 in accordance with the movement of the operation lever 11, and the spoke (see FIG. The rear wheel 31 is locked (see FIG. 3A). The locked state of the rear wheel 31 is maintained unless it is removed with the key 40.

  As shown in FIG. 7, when the operation lever 11 of the wheel lock (circle lock) 10 is operated, the protrusion 11 </ b> A of the operation lever 11 slides on the protrusion moving path 50. Since the protrusion 11A of the operation lever 11 hits the protrusion 16A of the wire fixing piece 16 on the end side in the locking direction of the protrusion moving path 50 along which the protrusion 11A moves, the wire fixing piece 16 is fixed to the fixing piece together with the movement of the protrusion 11A. It moves along the wire fixing piece moving path 52 of the guide member 17 and compresses the return spring 13 (see FIG. 11).

  Further, the outer wire 12 </ b> B is fixed and supported by the fixed piece guide member 17 and does not move, but the inner wire 12 </ b> A is pushed out by the wire fixing piece 16.

  Before the operation lever 11 is operated, as shown in FIG. 6B, the inner wire 12A is separated from the wire receiver 21, but only the inner wire 12A is moved to the frame 34 (FIG. 1) by the operation of the operation lever 11. As a result, the tip of the inner wire 12A pushes the wire receiver 21 and pushes the wire receiver 21 upward (rotates clockwise) as shown in FIG. 10B.

  Here, as shown in FIG. 5, since the protrusion 21A is formed on the wire receiver 21, when the wire receiver 21 is pushed upward as shown in FIG. 10 (B), as shown in FIG. 10 (A). 6A, the protrusion 21A rotates clockwise, and at the same time, the compressed lock spring 24 extends, and the lock pin 22 slides to the left in FIGS.

  Accordingly, when the operation lever 11 is pushed down in FIG. 2 (in the direction of arrow A) until the yoke 15 enters between the spokes and stops, the state shown in FIG. 10 (B) is reached, as shown in FIG. 10 (A). Then, the lock pin 22 slides and its tip fits into the lock groove 33, and the handle 32 is locked. Even when the position of the lock pin 22 and the position of the lock groove 33 do not coincide with each other, if the handle is slightly turned, the position of the lock groove 33 is aligned, and when the position is aligned, the lock spring 24 extends and the lock The pin 22 is fitted. In the locked state, the red display mark 25 (red region 25A in FIG. 5) showing the locked state can be seen through the display window 27A of the cover 27 shown in FIG. 10C.

  In the bicycle interlocking lock 4, a wire fixing piece moving path 52 for moving the wire fixing piece 16 is partially wrapped on the end side in the locking direction of the rear wheel 31 in the protrusion moving path 50 where the protrusion 11 </ b> A moves. . For this reason, when the protrusion 11A moves along the protrusion moving path 50, the wire fixing piece 16 moves along the wire fixing piece moving path 52 after the pin 15 is inserted between the spokes of the rear wheel 31, and the handle lock 20 Is locked. For this reason, the handle 32 is not locked first despite the state in which the rear wheel 31 can rotate (the yoke 15 does not lock the rear wheel 31).

  In the bicycle interlocking lock 4, the pushed inner wire 12 </ b> A pushes the wire receiver 21, and pushes the wire receiver 21 to lock the handle. In this case, the amount of rotation of the wire receiver 21 relative to the amount of movement of the inner wire 12A can be adjusted by the adjusting screw 14, and the interval between the inner wire 12A and the wire receiver 21 in FIG. 6B, FIG. The space between the wire receiver 21 and the cover 27 is a margin for adjustment.

  Conversely, when the bicycle interlocking lock 4 is unlocked, the key 40 of the wheel lock (circle lock) 10 is rotated clockwise from the state shown in FIG. 11A to release the restraint 15 (FIG. 7 ( A)). Then, the stretched return spring 19 in FIG. 3A contracts, and the action pulls the yoke 15 back into the circle lock body 18 to escape from between the spokes (not shown) and The lock is released. At the same time, the operation lever 11 is also pulled up along the guide hole (not shown) of the circle lock body 18 (see FIGS. 2 and 7).

  Also, as shown in FIG. 11, the protrusion 11 </ b> A moves on the protrusion moving path 50 and the protrusion 11 </ b> A moves away from the protrusion 16 </ b> A of the wire fixing piece 16 simultaneously with the return of the yoke 15. The piece 16 is pushed up along the wire fixed piece moving path 52 of the fixed piece guide member 17. Further, the inner wire 12 </ b> A is pulled by the wire fixing piece 16. The fixed piece guide member 17 and the outer wire 12B do not move.

  When the inner wire 12A is pulled, the inner wire 12A that has pushed the wire receiver 21 upward in FIG. 10B is drawn into the outer wire 12B. At the same time, the wire receiver 21 rotates counterclockwise by the action of the return spring 23, and the protrusion 21A of the wire receiver 21 pushes the groove 22A of the lock pin 22 toward the right in FIG.

  Therefore, the lock spring 24 is compressed, the lock pin 22 slides to the right in the figure, and the tip of the lock spring 22 comes out of the lock groove 33. In this process, the wire receiver 21 also pushes down the inner wire 12A by the return spring 23 (see FIG. 5) (see FIG. 6).

  Then, finally, the state shown in FIG. 6A is reached, the handle is completely unlocked, and the inner wire 12A and the wire receiver 21 are completely separated as shown in FIG. 6B. In the unlocked state, a blue display mark 25 (blue region 25B in FIG. 5) showing the unlocked state can be seen through the display window 27A of the cover 27 shown in FIG. 6C.

  In this bicycle interlocking lock 4, an empty running path 50 </ b> A that does not overlap with the wire fixing piece moving path 52 on which the wire fixing piece 16 of the inner wire 12 </ b> A moves on the unlocking side of the rear wheel 31 on the protrusion moving path 50 on which the protrusion 11 </ b> A moves. Is formed. For this reason, when the protrusion 11A starts to slide in the unlocking direction of the protrusion moving path 50 from the state shown in FIG. 11B, the wire fixing piece 16 moves on the wire fixing piece moving path 52, and the yoke 15 moves rearward. Before the wheel 31 is removed from between the spokes, the handle lock 20 is unlocked. Therefore, while the handle 32 is locked by the handle lock 20, the yoke 15 does not come out of the spokes of the rear wheel 31, and the rear wheel 31 cannot be rotated. There is no such thing as falling.

  Further, in this bicycle interlocking lock 4, when the key 40 of the wheel lock (circle lock) 10 is rotated to release the lock, the protrusion 11A moves along the protrusion moving path 50 by the action of the return spring 19, and returns. Although the wire fixing piece 16 is pushed up along the wire fixing piece moving path 52 of the fixing piece guide member 17 by the extension of the spring 13, the inner wire 12A may not move normally due to freezing or the like. For example, as illustrated in FIG. 9B, the inner wire 12 </ b> A may not move normally due to freezing or the like, and the wire fixing piece 16 may stop in the middle of the wire fixing piece moving path 52. In this state, as shown in FIGS. 8A and 8B, the wire receiver 21 is in the middle of swinging, and the tip of the lock pin 22 has not come out of the lock groove 33, and the lock of the handle 32 is released. It may not have been.

  At that time, as shown in FIG. 9B, if the wire fixing piece 16 has not moved to the position where the handle 32 is unlocked, the contact portion 16B of the wire fixing piece 16 is positioned in the protrusion moving path 50, When the protrusion 11A hits the contact portion 16B, the movement of the protrusion 11A by the return spring 19 is prevented. As a result, as shown in FIG. 9A, the yoke 15 is prevented from coming out from between the spokes of the rear wheel 31. For this reason, when the inner wire 12A does not move normally due to freezing or the like, the rear wheel 31 rotates despite the handle 32 being locked by the handle lock 20 (the handle 32 is not unlocked). Can be avoided.

  Further, in this state, as shown in FIG. 8C, the boundary line between the red region 25A and the blue region 25B of the display mark 25 can be seen through the display window 27A of the cover 27. Thereby, it is notified that the bicycle 15 is not unlocked and the bicycle 2 cannot travel. That is, since it is provided with two types of abnormality notification functions that the display mark 25 indicates that traveling is not possible and the lock of the yoke 15 is not released, it can be used more safely.

  In the present embodiment, the protrusion 11A is a cylindrical pin in the example shown in FIG. 2, but if the interlocking wire 12 can be pressed via the wire fixing piece 16 such as a rod shape, a polygonal shape, a pipe shape, or a plate shape. The shape, structure (pipe, double structure, etc.), material, etc. are not limited.

  In the present embodiment, the protrusion 16A with which the protrusion 11A abuts is provided on the wire fixing piece. However, the present invention is not limited to this. If the wire fixing piece 16 is pushed out by being pushed by the protrusion, a simple wall or the like may be used. The contact part which consists of may be sufficient.

  In addition, the wheel lock is a ring-shaped canopy inserted between the spokes of the rear wheel, a curved protrusion movement path along the movement trajectory of the canopy, and a linear wire fixing piece movement that moves the wire fixing piece. Although the path is provided, the present invention is not limited to this, and other shapes may be used as long as the protrusion moving path and the wire fixing piece moving path partially wrap on the lock side.
