Japanese Patent No. 3554852

However, the conventional bicycle lock has a problem that both the flexible wire body and the latch body cannot be unlocked unless both of the two locking mechanisms are unlocked, and it takes time to unlock. there were.
In addition, after unlocking the flexible wire body, forgetting to lock the other end, for example, in the support hole or the like, the flexible wire body may get in the way during operation.

  The present invention has been made in view of such circumstances, and has a bicycle lock that has high unlocking operability and that can securely lock the other end after unlocking the flexible wire body. The purpose is to provide.

  In order to solve the above problems and achieve such an object, the bicycle lock of the present invention is disposed in the casing so as to be reciprocally movable between the unlocking position and the locking position, and between the spokes of the wheels. And a flexible wire body having one end fixed to the casing and the other end inserted into and removed from a first support hole formed in the casing, and the yoke in the locking position. A locking mechanism for switching between fixation and release of the body, and a locking mechanism for turning the unlocking body along the reciprocating direction is formed in the casing, and the casing is formed in the casing. The other end of the flexible wire inserted into the first support hole is fixed using a pulling body fixed at the locking position, and the fixing is moved to the unlocking position side. The A stopper mechanism that is released when it is released, and a stopper member that is supported so as to be able to advance and retreat with respect to the reciprocating path of the engagement surface of the yoke body, and stops the movement of the yoke body from the locked position to the unlocked position; The casing is formed with a second support hole into which the other end of the flexible wire body extracted from the first support hole is inserted, and the other of the flexible wire body is inserted into the second support hole. When the end portion is inserted, the other end portion of the flexible wire body is locked in the second support hole, and the stopper member is moved backward from the reciprocating path of the engagement surface, and locked. The stop of the movement of the yoke body from the position toward the unlocked position is released.

According to this invention, since the fixing mechanism is provided, the locking mechanism is unlocked from the state in which the latch body is fixed at the locking position and the other end of the flexible wire body is fixed in the first support hole. Then, when the crown body is moved to the unlocking position side, the other end of the flexible wire body is released from the first support hole, and the other end can be extracted from the first support hole. become.
Therefore, it is possible to unlock the flexible wire body simply by unlocking the locking mechanism and moving the yoke body to the unlocking position side, and this bicycle lock can be provided with high unlocking operability. it can.
The stopper member is supported so as to be able to advance and retract relative to the reciprocating path of the engagement surface, and when the other end of the flexible wire body is inserted into the second support hole, the stopper member is The stopper member is positioned in the reciprocating path of the engaging surface when the other end of the flexible wire body is fixed in the first support hole because the engaging surface is moved backward from the reciprocating path of the engaging surface. Will be. In this state, when the unlocking mechanism is unlocked and the handle is moved from the locked position toward the unlocked position, the engaging surface of the handle is first brought into contact with the stopper member. Movement towards the side is stopped. At this time, the yoke body is maintained while being inserted between the spokes of the wheel, and the fixing of the other end portion of the flexible wire body in the first support hole is released as described above. Thereafter, when the other end portion of the flexible wire body is extracted from the first support hole, and the other end portion of the flexible wire body is inserted into the second support hole and locked, the stopper member reciprocates the engagement surface. Move backward from the movement path. As a result, the stopper member is separated from the engagement surface of the pinion body, and the pinion body that is inserted between the spokes of the wheel moves to the unlocking position and comes out of the space between the spokes, thereby unlocking the pinion body.
As described above, after unlocking the flexible wire body, if the other end portion is not inserted into the second support hole and locked, the stopper member is moved backward from the reciprocating path of the engagement surface to Since it cannot be moved to the unlocked position, it is possible to prevent forgetting to lock the other end of the flexible wire body in the second support hole when the bicycle is operated.

  Here, the casing is a tubular body curved so as to form an arc shape in a plan view, and one of the two peripheral end openings of the casing is moved by moving the crown body from the unlocked position to the locked position. The stopper member extends along the reciprocating direction of the yoke body, and the intermediate portion thereof extends in the circumferential direction and the radial direction of the casing. The end of the stopper member in the reciprocating direction is urged toward the outer side in the radial direction of the casing, and is rotatably supported around a rotation axis extending in a direction orthogonal to both The second support hole faces the inner side of the casing in the radial direction, and the other end of the stopper member in the reciprocating direction may advance and retreat with respect to the reciprocating path of the engagement surface.

In this case, the yoke moves from the unlocked position to the locked position so that it protrudes from one peripheral end opening in the casing and reaches the other peripheral end opening. It can be locked securely.
Further, the one end portion of the stopper member is biased toward the radially outer side of the casing, and is opposed to the second support hole from the radially inner side of the casing, and the other end portion of the stopper member is Since it moves forward and backward with respect to the reciprocating path of the engagement surface, the other end portion of the flexible wire body extracted from the first support hole is inserted into the second support hole, and the other end portion of the flexible wire body stops the stopper. When the one end of the member is pushed inward in the radial direction against the urging force directed outward in the radial direction of the casing, the stopper member rotates around the rotation axis, and the other end is engaged. It moves backward from within the reciprocating path of the surface. Thereby, the stop of the movement of the crown body from the lock position toward the unlock position is released, and the crown body moves to the unlock position.
From the above, it is possible to achieve high unlocking operability and to reliably lock the other end after unlocking the flexible wire body with a simple configuration.

  The first support hole is formed in a portion of the casing adjacent to the other peripheral end opening in the radial direction of the casing, and the other peripheral end opening is open along the reciprocating direction. You may open in the opposite direction.

  In this case, since the first support hole opens in the direction opposite to the direction in which the other peripheral end opening opens along the reciprocating direction, the first support hole is inserted into and removed from the first support hole. It is possible to prevent the reciprocating motion of the pinning body from interfering with each other, and high operability can be reliably provided.

  Further, the fixing mechanism includes an oscillating body that is swingably supported in the reciprocating direction, and an elastic body that restores and moves the oscillating body along the reciprocating direction. An annular groove is formed on the outer peripheral surface of the end portion, and the swinging body swings while the elastic body is elastically deformed with the insertion and removal of the other end of the flexible wire body with respect to the first support hole. The one end portion of the swinging body moves forward and backward with respect to the annular groove, and the one end portion of the swinging body enters the annular groove, and the locking position side along the reciprocating direction of the pinning body is The other end of the flexible wire body is fixed in the first support hole by approaching or abutting from the unlocking position side along the reciprocating direction to the other end of the swinging body. May be.

In this case, when the other end portion of the flexible wire body is inserted into the first support hole, first, the other end edge of the flexible wire body faces the one end portion of the rocking body toward the unlocking position side along the reciprocating direction. By pushing, the elastic body is elastically deformed, and the other end side of the rocking body is moved toward the locking position side along the reciprocating direction. Then, when the annular groove formed in the flexible wire body reaches one end of the oscillating body, the elastic body is restored and deformed, and the oscillating body is restored and moved so that the one end of the oscillating body enters the annular groove. You will enter.
Here, when the other end portion of the flexible wire body is inserted into the first support hole in a state where the crown body is locked, the other end portion side of the swinging body is in the locked position along the reciprocating direction as described above. It will move toward the side and will leave the end of the spring body. Therefore, it is possible to insert the other end portion of the flexible wire body into the first support hole and allow the one end portion of the swinging body to enter the annular groove regardless of the position of the bolt body. Thereby, it becomes possible to lock the coiled body and the flexible wire body in any order, and it is possible to provide good handling properties.
In addition, the other end of the flexible wire body is pulled out from the first support hole in a state where the crown body is positioned on the unlocking position side and the other end of the flexible wire body is inserted into the first support hole. When pulled in the direction, one end of the oscillating body is caught in the annular groove, so that the elastic body is elastically deformed and the oscillating body is oscillated, and one end of the oscillating body is detached from the annular groove. The other end of the body will be extracted from the first support hole. Therefore, it is possible to easily and surely realize a configuration in which the flexible wire body can be unlocked by unlocking the locking mechanism and moving the pinning body to the unlocking position side.

  Further, at one end of the rocking body, one end surface facing the unlocking position side along the reciprocating direction is formed as a flat surface, and the other end surface facing the locking position side along the reciprocating direction is You may form in a convex curved surface toward the locking position side.

In this case, since the one end surface of the one end portion of the oscillator is a flat surface, the one end surface and the inner surface defining the annular groove can be brought into surface contact with each other from within the first support hole. When the other end portion of the flexible wire body is extracted, force can be efficiently transmitted from the flexible wire body to the rocking body.
In addition, since the other end surface of the one end portion of the rocking body is a convex curved surface toward the locking position side along the reciprocating direction, the other end portion of the flexible wire body is connected to the one end portion of the rocking body. It becomes possible to insert into the first support hole while being caught on the other end face and sliding in a small amount, and the operability can be further improved.

  In addition, a cylinder having a handle fitted therein and an engagement groove formed on the outer peripheral surface, an engagement body mounted on the vehicle body frame and provided so as to be movable forward and backward with respect to the engagement groove, A handle comprising: an interlocking body that interlocks with the reciprocating motion of the pulling body, and moves the engaging body in the engaging groove backward from the engaging groove when the pulling body moves from the locking position to the unlocking position; A lock may be provided.

In this case, since the handle lock is provided in addition to the flexible wire body and the yoke body, the bicycle can be more reliably prevented from being stolen.
In addition, since the handle lock is provided with the interlocking body, it is possible to unlock not only the flexible wire body but also the handle lock simply by unlocking the locking mechanism and moving the crown body to the unlocking position. Thus, this bicycle lock can be provided with high unlocking operability.

  Moreover, the bracket in which the intermediate part between the one end part in the said flexible wire body and the other end part is hold | maintained may be provided in the said casing.

  In this case, a bracket is provided on the casing, and when the flexible wire body is not used, an intermediate portion of the flexible wire body can be held on the bracket, and the appearance of the bicycle lock can be improved. It is possible to prevent the flexible wire body from getting in the way while the bicycle is running.

  According to this invention, it has high unlocking operability, and the other end can be reliably locked after unlocking the flexible wire body.
