Description

  The present invention relates to a cylinder lock part which is a component part of a cylinder lock used for a house entrance.

  Cylinder locks used in current Japanese homes are assembled with decorative parts that make up the outside of the cylinder lock, locking / unlocking parts that perform locking / unlocking operations with keys, and housing parts that house the locking / unlocking parts. As a result, the cylinder lock system has become the mainstream. Such a cylinder lock is composed of, for example, a decorative cap and a decorative ring that constitute an exterior of the cylinder lock, a cylinder core that constitutes a locking / unlocking part, a housing that accommodates the cylinder core, and the like.

  Manufacturers have developed cylinder locks and locks in Japan, and there are a wide variety of types. Therefore, in order to respond to requests from customers, key repairers must stock a large number of locks and cylinder locks, which is a burden. In the following Patent Document 1, as a cylinder lock that can be used regardless of the type or model of the lock, a disk is provided with a groove inside the front cap constituting the decorative part, and a part of the groove is cut out in the circumferential direction. A concave part and a convex part are provided so that a disk-like part can be attached to the side surface of the outer cylinder which is a component part of the cylinder core.

Japanese Patent No. 4161491

  However, the technique described in Patent Document 1 cannot be attached if, for example, the axial depth of the groove of one part changes, and the outer diameter of the part attached via the disk-shaped part has changed. In some cases, installation is not possible. In the case of exchanging parts of cylinder locks, the key repairer cannot perform parts exchange work unless the parts desired by the customer are in stock. Therefore, there is a demand for a wide range of customer requests even with a small inventory. For this reason, there is a demand for an adjustment part that can adjust the shape of the cylinder lock part so that the parts can be replaced if the same kind of parts are in stock even if they are not the same parts.

  Cylinder locks can be classified into, for example, the method of attaching to the lock, the performance of the keys such as the master key and reverse master key, the difference in the finish color of the cylinder lock, the size of the outer diameter of the cylinder lock, etc. There are hundreds of types. For example, even if the finish color of the cylinder lock is different, it can be replaced because it can be installed, but if only a cylinder core with a different diameter from the cylinder core of the cylinder lock requested by the customer is in stock, replace the cylinder core. I can't. In that case, the cylinder core of the same diameter must be ordered. Since it takes time to order parts, the customer looks for another repairer who stocks the cylinder core to be replaced, and the repairer cannot perform the repair, and cannot sell.

  Currently, there is no sale of cylinder cores alone, and key repairers must stock cylinder locks for each cylinder core of different diameters, even if they are cylinder cores of the same manufacturer, and stock many parts that do not know when they will sell This is a huge burden for repairers.

  Therefore, the present invention has been invented to solve the above-described problems, and an object of the present invention is to provide a cylinder locking part to which a different type of cylinder core can be attached depending on the size of the diameter.

Is provided in the locking / unlocking part protruding radially. An engaging groove that engages with the protruding portion, and a cutout portion that is provided in a row in the axial direction of the cylindrical shape and that can be provided with a protrusion that protrudes inward from the inner wall surface of the housing component. , is provided, in different sizes state of the unlocking component and a radial direction of the accommodating part, formed by arranging the gap provided between the unlocking component and the accommodating part.

According to the cylinder lock part according to the present invention, even when a gap is formed between the locking / unlocking part and the housing part and the cylinder lock cannot be assembled, the cylinder lock part is arranged and attached to the gap part. The cylinder lock can be assembled. As a result, if the key repairer stocks cylinder cores of the same manufacturer as the manufacturer desired by the customer, the cylinder lock can be replaced by attaching the cylinder lock parts. Moreover, the notch part is formed in the components for cylinder locks. Therefore, the cylinder core can be attached to the housing even when the protrusion is formed on the inner side surface of the housing.

In addition, the cylinder locking part according to the present invention is configured such that one cylinder locking part and other cylinder locking parts having different inner and outer diameters can be stacked . Therefore, even when there are a plurality of types of cylinder cores depending on the size of the outer diameter, cylinder cores of various diameters can be obtained by stacking cylinder locking parts on the cylinder core. As described above, the cylinder locking parts according to the present invention can be stacked, so that they can be widely adapted to existing parts types.

  In addition, since the cylinder lock parts are attached in the axial direction in the same way as the locking / unlocking parts, the cylinder core parts can be easily attached in the same way as conventional cylinder core housings. Can be done.

  Further, the cylinder locking part is configured to be assembled to the locking / unlocking part by an interference fit. Therefore, compared with the case where the cylinder locking part is divided in half, for example, the operator does not need to hold the combined state of the cylinder locking part by hand, and easily attaches it. be able to.
