And
[0002]
[Prior art]
This type of bicycle lock provided with a lock body and a lock housing which are locked and unlocked at the distal ends of two rods which are hinged at the base and opened and closed by a vehicle body includes, for example, the prior application of the present applicant. There is Japanese Patent Application No. 8-324756.
[0003]
[Problems to be solved by the invention]
A lock body is attached to the tip of one of the two rods that opens and closes, and the lock body at the tip of the other rod is locked to the lock body with a tire in between. Since both operations involve operations from both sides of the tire, it is desirable that the operation be performed easily and smoothly by the user.
Therefore, the problem to be solved by the present invention is that both the locking operation and the unlocking operation of the lock attached to the ends of the two relatively long rods can be used easily and smoothly for the user. There is in doing so.
[0004]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention includes two rods of an appropriate length that reach the tire from the mounting position on the vehicle body, and a lock mechanism is built in the tip of one rod to lock the end surface. A lock body with a hole is attached, and a lock housing that is fitted in the lock hole and locked in the lock body is attached to the tip of the other rod, and the two rods can be opened and closed with respect to the vehicle body. In the bicycle lock to be attached, the lock housing includes a lock housing portion provided with a protrusion and a cutout portion along an axial direction, and the lock body has a lock housing portion on the inner side of the locking hole. On the inner end of the cylinder lock mechanism fitted to the other end surface of the lock body so as to freely rotate at a predetermined angle while slidably fitting the kicker that moves backward against the sliding restoring spring by inserting By fitting the square shaft of the inner end of the cylinder lock mechanism, A cylindrical lever that is pivoted along the inner peripheral surface of the lock body and that engages the kicker and the lock hook part from the side face is fitted with the hook part provided at the tip. A bicycle lock is provided, characterized in that a pivot biasing spring is provided that has one end hooked on the other end and the other end fixed in the lock body, and constantly biases the lever in the locking direction.
[0005]
The main lock configured as described above is designed to lock, and when the tip of the lock housing is inserted into the lock hole on the lock body side, the kicker retracts against the bias of the sliding restoring spring, and the lock housing is cut out. When the lever reaches the collar at the tip of the lever, the lever that has been brought into contact with the kicker from the side at the time of unlocking is predetermined along the inner peripheral surface of the lock body by the biasing spring. It turns at an angle, and the hook is fitted into the notch of the lock hook inserted at a predetermined position to automatically lock.
[0006]
Also, when the key inserted into the cylinder lock mechanism is rotated by a predetermined angle against the turning biasing spring when unlocking, the lock housing whose notch is released from the hook of the hook as the lever rotates backward is locked at the time of locking. It is urged by the sliding restoring spring that has been compressed through the kicker, and automatically escapes out of the locking hole to release the lock.
[0007]
As described above, the bicycle lock is operated along the axial direction both when locking and when it is opened. Therefore, this type of lock that needs to be operated from both sides with the tire in between is opened. It can be used smoothly with easy locking and locking operations.
The present invention solves the above problems as described above.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
In the figure, reference numerals 1 and 2 denote two relatively long rods that are connected to each other so as to be openable and closable, with a base end hinged by a pin 3 being attached to the body of the bicycle. Reference numeral 6 denotes a lock body which is pivotably connected to the distal end of the rod 2 in a substantially L-shape, and 6 is a lock body which is also pivotably coupled to the distal end of the other rod 2 by the pin 7 so as to face the lock casing 4.
[0009]
As shown in the figure, the lock housing 6 has a lock housing portion 10 provided with ridges 8 and cutout portions 9 provided so as to be alternately uneven along the axial direction.
The lock body 6 has a locking hole 11 into which the lock portion 10 is inserted on one end surface facing the lock housing 6, and a cylinder lock mechanism 12 that is freely rotatable by a predetermined angle is fitted on the other end surface. .
[0010]
As shown in FIG. 1, a kicker 13 having a ridge 13 ′ up and down and slidably fitted inside the locking hole 11 as shown in FIGS. Is inserted into the locking hole 11, the coil-shaped sliding restoring spring 14 provided on the back side is compressed and retracted.
[0011]
When the lock 10 of the lock housing 4 is advanced to the predetermined position shown in FIG. 2, the angle shaft 12 ′ of the inner end of the cylinder lock mechanism 12 is fitted, and together with the cylinder lock mechanism 12 on the inner peripheral surface of the lock body 6. A cylindrical lever 15 fitted so as to be pivotable along one end is hooked to a base of the lever 15 and the other end is attached to a turning biasing spring 16 held by the lock body 6 via a cylinder holder 17. Energized and automatically swiveled in the locking direction, fitted with L-shaped flanges 18 provided on both sides of the tip in the same direction in the upper and lower cutouts 9 that have advanced following the ridges 8 respectively. And lock as shown in FIG.
[0012]
In the locked state shown in FIG. 2, the cylinder locking mechanism 12 rotates integrally with the turning of the lever 15 to the locking position, and the tumbler 19 is fitted into the groove 20 on the inner surface of the lock body in the same manner as a known cylinder lock. Thus, the key 21 is held in a locked position, and the key 21 can be pulled out in a portable manner.
[0013]
At the time of unlocking, when the key 21 inserted into the keyhole is reversely rotated against the turning biasing spring 16, the lever 15 is turned following the reverse rotation of the inner shaft 12 ′ of the cylinder lock mechanism 12. The collar part 18 comes off from the notch part 9 of the lock collar part 10.
The lock housing 4 with the notch 9 opened is urged by the sliding restoring spring 14 compressed through the kicker 13 at the time of locking, and automatically escapes out of the locking hole 11 as shown in FIG. And the lock is released.
[0014]
On the other hand, the flange portion 18 of the lever 15 comes into pressure contact with the protrusion 13 ′ of the kicker 13 moving forward while replacing the lock rod portion 10 from the side surface, and waits for the next locking.
When locking, the flange 18 reaches the notch 9 while rubbing the side surface of the protrusion 8 located in front of the notch 9.
[0015]
In FIG. 1, reference numeral 22 denotes a bracket of the pin 3 that hinges the bases of the two rods 1 and 2, 23 denotes a hinge of the pin 24 so that the bracket 22 can be moved up and down, and as shown in FIG. As shown in FIG. 4, the clamp fitting 26 clamped to the saddle post 25 of B is an annular attachment fitting attached to the lower side of the saddle post 25 and fastened to the lower portion of the seat pipe 27. The mounting bracket 26 is integrally extended from the bracket, and a lock body 6 in which the lock casing 4 is coupled in a locked state is fitted into a holder 27 having a cylindrical shape in a lateral direction so that an unused lock can be secured. It should be able to carry safely.
[0016]
In carrying out the present invention, the structure in which the two rods 1 and 2 can be opened and closed with each other is configured such that the direct pin hinges of both rods in the embodiment are indirect pin hinges with brackets interposed, or the rods are opened and closed like a wire. Adopting a flexible rod that can be used is optional.
[0017]
【The invention's effect】
