TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for fixing a cylinder lock to an automobile panel and a method for fixing the cylinder lock to an automobile panel .
[0002]
[Prior art]
As a structure for fixing a cylinder lock to, for example, a door panel of an automobile, a structure described in Japanese Utility Model Laid-Open No. 5-10665 is known. In this conventional example, a cylinder lock is inserted through a handle base of a door outside handle device and a mounting hole formed in a door panel, and is fixed to the door panel using a U-shaped elastic metal fitting.
[0003]
However, the above-described conventional example has the following disadvantages. In other words, since the cylinder lock uses the elasticity of the legs of the U-shaped elastic fitting to press the flange formed on the head of the cylinder lock against the handle base, 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 disposed inside the door body is fixed to the 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. If the step of fixing the lever and the like is separated from the step of attaching the handle to the handle base, it becomes impossible to make the cylinder lock into a sub-assembly, and the production efficiency of the cylinder lock and, consequently, the production efficiency of the handle device decrease.
[0004]
As a fixing structure that can solve such a defect, for example, one described in Japanese Patent Application Laid-Open No. 7-305542 is known. In this conventional example, it is possible to mount the cylinder lock 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 it 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 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.

[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
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 main body 1c 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 in the illustrated example. However, they may be formed separately and fixed to the door panel 4 individually.
[0013]
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 only when a key plate having a corresponding unlocking code is inserted. The relative rotation of the cylinder 3b with respect to 3a is allowed. The cylinder case 3a is formed in a cylindrical shape having a rotation preventing projection 3c on the peripheral edge, and a cut-out flat portion 3d facing the rear of the formation position of the rotation preventing projection 3c slightly smaller than the outer diameter is formed.
[0014]
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 of the cylinder case 3a. The opening 9 is formed to have a diameter slightly smaller 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.
[0015]
Further, the lock holding portion 2 has a support 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.
[0016]
Reference numeral 6 denotes a fixed plate 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 flat portions 3d of the cylinder case 3a, and positioning holes 8 at four corners. Then, the fastening through hole 13 is perforated.
[0017]
In this embodiment, the cylinder lock 3 is fixed to the panel 4 as follows. The cylinder lock 3 is in a sub-assembly state in which a cylinder 3b is inserted into a cylinder case 3a, and a locking device connecting lever 3e is connected to a rear end of the cylinder 3b. First, as shown in FIG. The fixing plate 6 is mounted on the cylinder lock 3 by inserting the fixing piece 6a into the portion 3d from above. Thereafter, the cylinder lock 3 is inserted into the holding cylinder 5 from the back side of the cylinder case 3a while the rotation preventing projection 3c is aligned with the positioning groove 5b of the holding cylinder 5 and the fastening through-hole 13 of the fixing plate 6 is aligned with the stud 11. insert. 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, and further, the screw 14 is screwed into the nut 12 to temporarily fix the fixing plate 6 to the handle case 1a. The stud 11 is inserted through the mounting hole 4b of the handle fixing piece 4a protruding from the handle mounting opening (not shown) of the door panel 4, and the fixing plate 6 is fastened together with the handle case 1a to the panel 4 with the nut 15.
[0018]
With the handle case 1a fixed to the door panel 4, the cylinder lock 3 is restricted from moving forward and backward by the fixing plate 6, and is fixed at a predetermined position. In the fixed state, the peripheral edge of the cylinder lock 3 abuts on the projection 9b of the ceiling wall surface 9a, and as shown in FIG. 2, the key plate is inserted into the key insertion portion 3f of the cylinder 3b exposed from the opening 9. By rotating the door, the lever 3e can be operated to lock and unlock the door. Further, water that has entered through the gap between the ceiling wall surface 9a and the tip of the cylinder 3b is quickly discharged out of the holding cylinder 5 through the drainage opening 5a, and does not stay in the holding cylinder 5, so that the cylinder 3b may be corroded. 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 a pressing force or a prying force is applied to the tip of the cylinder lock 3 for the purpose of unauthorized 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. In addition, since 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 metal, the strength does not decrease and the weight of the component can be reduced.
