Description

  The present invention relates to a cylinder lock.

  A cylinder lock described in FIG. 6 and below of Patent Document 1 is known as a cylinder lock that is directly transmitted to a locking / unlocking target without converting a rotational operation force to the cylinder lock into a translational movement by a lever or the like. . In this conventional example, the cylinder lock is formed having a case, a plug inserted into the case, and a connecting rod connected to the rear end of the plug.

  A projecting first coupling device is formed on the connecting rod, and a cardan universal joint is configured by being fitted to a concave second coupling device formed at the rear end of the plug. In order to connect the plug that can move relative to each other and the connecting rod, a regulating wall that restricts the movement of the connecting rod in the removal direction is indispensable.If no pin is used, the regulating wall is an obstacle wall during assembly. Become.

  In order to avoid this, in the above-described conventional example, the case is formed as a connection body of semi-cylindrical parts, and the connection state is maintained by sandwiching the protruding portions of the connection rods by the semi-cylindrical parts.

  However, in the above-described conventional example, dividing the case has a drawback that it causes a cost increase such as an increase in the number of assembly steps.

  The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a cylinder lock capable of directly transmitting a rotational operation force to a plug to an object to be locked and unlocked with a simple structure.

  Another object of the present invention is to provide a vehicle door handle device using the cylinder lock.

  The cylinder lock includes a plug 2 that is rotatably inserted into the cylinder case 1 and a connecting rod 3 that is connected to the rear end of the plug 2. In order to connect the plug 2 and the connecting rod 3 so as to be capable of precessing movement, a connecting projection 5 that fits into a connecting recess 4 formed in the connecting rod 3 is provided at the rear end of the plug 2. The plug 2 and the connecting rod 3 are formed by inserting a retaining ring 7 into a mounting slit 6 provided in the connecting rod 3, and the retaining ring 7 is locked to the proximal end portion of the connecting projection 5. To prevent both sides from leaving.

  The connecting protrusion 5 and the connecting rod 3 are irregularities that can be meshed within the range of the variable crossing angle with either the outer surface of the connecting protrusion 5 or the inner peripheral wall surface of the connecting recess 4 being convex. The rotational operation force to the plug 2 is transmitted to the connecting rod 3.

  Therefore, in the present invention, the connecting rod 3 can be connected simply by mounting the retaining ring 7 after the rear end of the plug 2 is fitted into the connecting recess 4, so that the structure is simple and the assembly is performed. Workability is also improved. That is, if an attempt is made to construct a universal joint mechanism that has complete freedom in the direction of precession with respect to the rotation axis of the plug 2, it is necessary to satisfy the requirements such as maintaining the geometric relationship between the two. As an example, it becomes a complicating factor of the structure so that case division is necessary.

  On the other hand, in the present invention in which the plug 2 and the connecting rod 3 are connected only by locking the retaining ring 7 to the base end portion of the connecting protrusion 5 formed on the plug 2 side, the structure is unnecessarily complicated. As a result, the assembly efficiency is also improved.

  In addition, a simple connection method in which the plug 2 and the connecting rod 3 are pin-coupled so as to be swingable within a preset plane including the rotation axis of the plug 2 is also possible. In order to displace in the direction of precession, it is necessary to rotate the plug 2, and when applied to a cylinder lock in which a rotation operation is prohibited in the locked state, there arises a problem that the degree of freedom of adjustment is reduced.

  In this respect, according to the present invention, the connecting protrusion 5 on the plug 2 side is loosely fitted in the connecting recess 4 and generally the retaining ring 7 mounted so as not to move relative to the shaft is attached to the shaft, that is, the connecting protrusion 5. Simplify the structure and operation by securing the degree of freedom of precession by locking it to the base end of the lens, and realizing the transmission of rotational displacement with unevenness that can be engaged at least partially during tilting It is intended to improve reliability.

  As for the unevenness, when the crossing angle is changed, if some engagement is ensured, other engagement is allowed to be released, and if such conditions are satisfied, various uneven shapes can be used. For example, the concave shape is formed by a hexalobular hole, and the convex shape can be changed to a star shape (hexalobular shape) meshing with the convex shape.

  When the cylinder lock is assembled by inserting the plug 2 from the front end side of the cylinder case 1, that is, from the front side where the unlocking key insertion port is opened, the retaining ring 7 is larger than the diameter of the plug 2. If formed into a diameter, the retaining ring 7 serves as a stopper when the plug 2 is pulled out, so that it is possible to increase the resistance against unauthorized operation of pulling out the plug 2.

The above cylinder lock can be applied to a door handle device that transmits a rotational operation to the cylinder lock as a direct rotational displacement to the door lock side on the vehicle side.
