Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a cylinder lock with a cover attached to a vehicle door, for example.

(Prior art and its problems) Conventionally, as a cylinder lock with a cover, for example, Jikken Sho 62
-12763 is known. According to this, when the cover for covering the lock hole is rotated against the biasing force of the spring to open the lock hole, a predetermined engaging groove formed on the cover side is provided on the rotor side of the cylinder lock. When the pin is engaged and the open state of the cover (open state of the cover) is maintained, after that, after inserting the key into the lock hole and rotating the rotor to perform the locking operation, the key is pulled out from the lock hole. There is disclosed a configuration in which the engagement state of the pin is released and the cover automatically returns to the state of covering the lock hole (closed state of the cover).

However, according to the configuration of the related art, since the lock hole is automatically covered only when the key is used for operation, if the cover is opened after being locked due to mischief, for example, the open state is maintained as it is. In order to avoid this, it is necessary to perform a wasteful operation of using the key again, and when the cylinder lock is attached to the door of the vehicle, when running with the cover open. Not only the appearance is bad, but there is also a possibility that water intrusion into the lock hole may not be prevented, and there is a problem that the automatic return effect of the cover is diminished.

(Means for Solving Problems) The present invention has been made to solve the problems of the prior art, and is rotatably attached to the front side of the lock hole and always covers the lock hole. In a cylinder lock with a cover, which is maintained in a state and which is provided with a cover provided with engaging means for maintaining the opened state when the lock hole is opened, a predetermined lock for releasing the engagement by the engaging means. A key cylinder lock with a cover that is equipped with an actuator that is activated by a signal and that can automatically return to the closed state even if the cover is kept open against the operator's will. The purpose is to provide.

(Function) The cover that has been rotated during the locking / unlocking operation is maintained in the unlocked state, but if the cover is maintained in the unlocked state other than during the locking / unlocking operation, the actuator is actuated to lock the cover. Rotate automatically to cover.

(Embodiment) FIG. 1 shows an embodiment of the present invention. A cylinder lock 1 with a cover is attached to a door panel 2 on the driver side of an automobile, for example, with the vertical direction in the same figure as the vertical direction. The rotor 3 of the cylinder lock 1 is rotatable about a central axis O inside a body 4 having a square plate shape on the front side and a cylindrical shape on the rear side, and a lock hole 5 is formed in the rotor 3. ing. In addition, the tip side of the body 4,
That is, on the rear end side (right end side in FIG. 1) of the cylinder lock 1, a return spring 6 for automatically returning the rotated rotor 3 to the original position is attached. A lock plate cam 7 connected to an unlocking mechanism (not shown) and an E-shaped clip 8 for preventing separation are attached to the rear side.

On the other hand, a cover 9 having a substantially square dish shape is attached to the front surface side of the body 4, that is, the key insertion side of the lock hole 5, and the boss portion 9a as a rotating shaft formed in one corner of the cover 9 is The boss portion and the bottom surface of the support shaft hole portion 10 are projected into the support shaft hole portion 10 formed on the back side of the one corner of the front side of the body 4.
Between the collar 10 which is inserted into the tip of 9a and is locked to the body 4, the cover 9 biases the lock hole 5 in the direction to cover the lock hole 5 and the cover 9 in the direction to press the body 4 side. Return sprig 12 is installed.

On the other hand, the body 4 is provided with an electromagnetic solenoid 17 as an actuator for advancing and retracting the plunger 16 biased by the spring 15 according to the energized state of the exciting coil 14 housed in the case 13. solenoid
The exciting coil 14 of 17 has a running state of the vehicle, for example, when a passenger operates a separate switch, when the engine is started, when the vehicle speed reaches a predetermined speed, or when a shift lever position change is detected. Accordingly, a detecting means 18 for energizing the plunger 16 for a predetermined time so as to attract the plunger 16 into the exciting coil 14 is connected.

A slide plate 19 is housed in a recess 5a formed on the front side of the rotor 3, and a slide pin (formed on the back side of the cover 5 as shown in FIG. 3 is formed on the slide plate 19. And a guide groove 9b formed of a substantially L-shaped long arc-shaped portion 9n and a short arc-shaped portion 9m) is formed, while the front surface of the rotor 3 is covered with a cap 20. As shown in FIG. 2, a vertically long lock insertion hole 20a and a horizontally long slide hole 20b are formed in the upper portion of the lock insertion hole 20a, and the slide pin is inserted into the slide hole 20b. That is, the slide plate 19 rotates together with the rotor 3 and is free to move in the recess 5a along the slide hole 20b.

A packing 21 is interposed between the door panel 2 and the body 4.

Next, the operation of the embodiment thus constructed will be described with reference to FIGS. 3 to 8.

First, as shown in FIG. 3, when the cover 9 is closed, that is, when the front side of the lock hole 5 is covered, the slide plate 19 is in a position to cover the lock insertion hole 20a and the slide pin 19a is guided. The groove 9b is engaged with one end (upper end in FIG. 3) of the long arc-shaped portion 9n.

From this state, as shown in FIG. 4, when the cover 9 is rotated clockwise in the same figure, the slide pin 19a moves relative to the guide groove 9b from the position of the long arc 9n to the position of the short arc 9m. When it is moved to the boundary portion between the long arc-shaped portion 9n and the short arc-shaped portion 9m, the slide pin 19a moves along the slide hole 20b. That is, the slide plate 19 moves to the right in the figure. Here, when the cover 9 continues to rotate further, the slide pin 19a moves to the position of the end of the slide hole 20b (the right end shown in the same figure), and the tip of the plunger 16 covers the cover as shown in FIG. The rear surface of the engagement projection 9c is formed on the back surface of the engagement projection 9c and has a triangular cross section. As a result, the lock insertion hole 20a is exposed and the cover 9
The open state of is maintained.

When the cover 9 is in the open state, if the cover 9 is forcibly floated in the direction in which it is separated from the body 4 against the biasing force of the spring 12, the plunger 16 and the engaging projection 9c.
The locked state with is released, and the cover 9 returns to the closed state by the urging force of the spring 12.

From the opened state of the cover 9, as shown in FIG. 5, when a key is inserted into the lock hole 5 and the rotor 3 is rotated to perform an unlocking operation, the rotor 3 and the slide plate 19 are rotated,
As a result, the slide pin 19a moves to the position of the end portion (lower end portion in the figure) of the short arc-shaped portion 9m. When the rotor 3 rotates, the slide pin 19a abuts on the push-up slope 9e formed on the back surface side of the cover 9 as shown in FIG. 7, so that the cover 9 resists the urging force of the spring 12. Body 4
Move away from. Therefore, at the end of the unlocking by the rotation of the rotor 3, the plunger 16 has the engaging projection.
The locked state with 9c is released, and at the same time when the key is removed, the cover 9 returns to the closed state by the urging force of the spring 12.

After completion of this unlocking operation, when the cylinder lock 1 is locked and the cover 9 is maintained in the open state again due to mischief or the like and the operation is continued as it is, the detecting means 18 operates and the plunger 16 causes the exciting coil 14 to move. Since it is sucked in, the cover 9 automatically returns to the closed state by the urging force of the spring 12.

Although the electromagnetic solenoid is used as the actuator in the above-described embodiment, the slide pin 19a may be moved back and forth by a rack and pinion gear or the like using a motor or the like.

(Effect of the Invention) As described above, according to the present invention, the lock hole is rotatably attached to the front side and is always kept in a state of covering the lock hole, while the lock hole is opened when the lock hole is opened. A cover-equipped cylinder lock comprising a cover provided with engagement means for maintaining an open state, the actuator being actuated by a predetermined signal for detecting an operation state of the vehicle such as a vehicle speed in order to release the engagement by the engagement means. Since the structure is provided, even if the lock hole is maintained in an unnecessary open state due to mischief or the like other than when the locking / unlocking operation is performed, the lock hole is covered by the operation of the actuator even if the vehicle is driven without noticing the driving vehicle. Since the cover is automatically rotated to the state, for example, when the cylinder lock is attached to the door of the vehicle, it is possible to prevent not only appearance but also prevent water from entering the lock hole.
The automatic return function of the cover can be made more effective.
