DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a cylinder lock to an automobile panel.

[0002]

2. Description of the Related Art As a structure for fixing a cylinder lock to, for example, a door panel of an automobile, a structure disclosed in Japanese Utility Model Laid-Open No. 5-10665 is known. In this conventional example, a cylinder lock is inserted from a handle base of a door outside handle device and a mounting hole formed in a door panel,
It is fixed to the door panel using a U-shaped elastic bracket.

However, the above-described conventional example has the following disadvantages. In other words, the cylinder lock uses the elasticity of the legs of the U-shaped elastic metal fitting to press the flange formed on the head of the cylinder lock against the handle base. Therefore, it is necessary to form the flange on the head of the cylinder lock. Therefore, it is necessary to insert the cylinder lock into the mounting hole from the front side of the handle body. On the other hand, a lever or the like for operating a lock device arranged inside the door body is fixed to an end of the cylinder lock. In this state, the mounting hole cannot be inserted, so that the cylinder lock cannot be inserted into the handle base. For mounting, it is necessary to insert the cylinder lock into the mounting hole with the lever or the like removed, and then fix the lever or the like from the back side. Separating the process of fixing the lever etc. from the process of mounting on the handle base makes it impossible to make the cylinder lock a sub-assembly, which increases the manufacturing efficiency of the cylinder lock,
As a result, the manufacturing efficiency of the handle device is reduced.

As a fixing structure capable of solving such a defect, for example, a structure described in Japanese Patent Application Laid-Open No. Hei 7-305542 is known. In this conventional example, the cylinder lock can be mounted from the back side of the handle base in order to screw the fixing piece formed on the case of the cylinder lock to the handle base, but has the following disadvantages. That is, when the mounting position of the cylinder lock is changed due to a change in the design of the handle main body or the handle base, the formation position of the fixing piece also needs to be changed, which is a basic structural unit of the cylinder lock. There is a disadvantage that the types of cases increase.

FIG. 2 shows a door outside handle device 1 of an automobile to which the present invention is applied. The handle device 1 has a handle case 1a and a handle body 1c that is rotatably supported around a pivot 1b fixed to the handle case 1a. The handle case 1a has a lock holding portion 2 opposite to the holding portion of the pivot 1b, and the cylinder lock 3 is held by the lock holding portion 2. In the illustrated example, the lock case 2 and the supporting portion of the pivot 1b are formed integrally with the handle case 1a, but they may be formed separately and fixed to the door panel 4 individually.

As shown in FIGS. 1, 3, and 4, the cylinder lock 3 is formed by rotatably inserting a cylinder 3b into a cylinder case 3a, and when a key plate having a corresponding unlocking code is inserted. Only relative rotation of the cylinder 3b with respect to the cylinder case 3a is permitted. The cylinder case 3a is formed in a cylindrical shape having a rotation preventing projection 3c on a peripheral edge thereof, and a cut-out flat portion 3d facing the rear of the formation position of the rotation preventing projection 3c at a smaller interval than the outer diameter is formed.

In order to hold the cylinder lock 3, a holding cylinder 5 is protruded from the lock holding portion 2 of the handle case 1a. The holding cylinder 5 is formed in a substantially cylindrical shape having an inner diameter dimension into which the cylinder lock 3 can be fitted, and penetrates through the concentric opening 9 to the surface side of the cylinder case 3a. The opening 9 is formed to have a slightly smaller diameter than the inner diameter of the holding cylinder 5, the ceiling wall surface 9 a is left on the periphery, and a projection 9 b that comes into contact with the head of the cylinder 3 b is annularly protruded from the ceiling wall surface 9 a. Further, a lower portion of the holding cylinder 5, specifically, a wall surface which faces vertically downward when the handle case 1a is fixed to the door panel 4, is cut out over the entire length to form a drain opening 5a.

Further, the lock holding portion 2 has a column 10 protruding toward the back surface. A plurality of struts 10 (four in the illustrated example) are arranged at substantially symmetric positions with respect to the center of the holding cylinder 5, and one of the studs 11 for fixing a panel is provided with a nut 12 on the strut 10 at a point symmetric position. Are respectively buried, and positioning bosses 7 are protruded from the tips of the remaining columns 10. The surface 12a of the nut 12, the base surface 11a of the stud 11, and the base surface 7a of the positioning boss 7 are set at the same height and belong to the same plane.

Reference numeral 6 denotes a fixed plate, which is formed of a metal plate such as an iron plate so as to obtain predetermined rigidity and strength. This fixing plate 6 is formed in a U-shape with two fixing pieces 6a arranged at a slightly larger interval than the cut-off plane portions 3d of the cylinder case 3a, and positioning holes 8 are formed at four corners. The fastening through-hole 13 is perforated.

In this embodiment, the cylinder lock 3 is fixed to the panel 4 as follows. In the cylinder lock 3, a cylinder 3b is inserted into a cylinder case 3a, and a lever 3e for connecting a locking device is provided at the rear end of the cylinder 3b.
It is in a sub-assembly state where
As shown in FIG. 1, the fixing piece 6a is
The fixing plate 6 is mounted on the cylinder lock 3 by inserting the fixing plate 6 from above. Thereafter, the rotation preventing projection 3c is inserted into the positioning groove 5b of the holding cylinder 5, and the fixing through hole 1 of the fixing plate 6 is inserted.
The cylinder lock 3 is inserted into the holding cylinder 5 from the back side of the cylinder case 3a while matching the studs 3 with the studs 11, respectively. Next, the positioning boss 7 of the column 10 is fitted into the positioning hole 8 to finely adjust the posture of the fixing plate 6. Further, the screw 14 is screwed into the nut 12 to fix the fixing plate 6.

Is prevented. Further, even if the mounting position of the cylinder lock 3 is changed due to a change in the design or the like of the handle case 1a, the fixing plate 6 is simply changed according to the handle case 1a without making any change to the cylinder lock 3. Since it can respond, the versatility of the cylinder lock 3 is improved. In addition, even if pressing force and prying force are applied to the tip of the cylinder lock 3 for the purpose of illegal destruction,
Since the fixing plate 6 has rigidity, the fixing plate 6 is dispersed at the fixing portion of the fixing plate 6 of the handle case 1a, and the fixing plate 6 itself is fixed to the panel 4,
The force is also distributed to the panel 4 so that stress is not concentrated on a specific portion of the handle case 1a. As a result, even if the handle case 1a is formed of a synthetic resin material having a lower strength than a metal, the strength does not decrease and the weight of the component can be reduced.
