Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button-type cylinder lock for vehicles.

Conventionally, as a button-type cylinder lock attached to the back door (opening/closing body) of pan-type cars, etc., for example, the first
There is something like the one shown in Figure 2. .

That is, the actor of the bank door 1 (hereinafter referred to as the opening/closing body 1)
The button type lock 5 attached to the panel 3 is attached to the case 7 attached to the actuator panel 3 and this case 7? Consisting of a button 9 that slides together, and a cylinder 11 that slides together with the button 9, the cylinder 11 is
It is connected to a locking mechanism 15 of the opening/closing body l via a linkage 13.

In addition, in Fig. 1 and Fig. 2, 17 is a case cover attached via a case washer 19 between the actuator panel 3 and the case 7, 21 is a button cover, and 23 is a shutter cover at the upper end opening of the cylinder 11. 25 is a shutter attached to be openable and closable, 27 is an inner panel of the opening/closing body l, 29 is a water receptacle provided on the linkage 13 between the cylinder 11 and the locking mechanism 15, and p! 31 and 33 are strikers attached to the vehicle body 35 and the bottom of the opening/closing body 1.

By the way, in such a conventional button-type cylinder lock, the case cover 17 and the button cover 21 are in metal contact, so the sealing performance at the contact surface between the members is extremely poor, and therefore rainwater and There is a problem that car wash water easily enters the inside of the cylinder and leaks into the car interior.

Rainwater, car wash water, etc. that have entered the inside of the opening/closing body 1 generally flow down to the member 29 through the drain hole 37 provided in the case 7, as shown by the first arrow. This water receptacle is guided by the member 29 and drained out of the vehicle from a water drain hole (not shown) provided at the lower end of the opening/closing body l.However, as mentioned above, if the sealing between the members is poor, The amount of water that enters the inside of the opening/closing body 1 is also large.

When the amount of water that enters increases in this way, the water receiver is
9, it becomes impossible to guide the locking mechanism 15 and the rear end surface of the rear floor of the vehicle body 35 gets wet. Therefore, it is necessary to take measures to prevent the locking mechanism from rusting, and the prevention of water leakage is insufficient. There was a problem that the quality of the vehicle deteriorated.

In addition, if the sealing properties between the members are poor, there is a problem in that the water accumulated between the contact surface of the coupe and the button 9 freezes in cold weather, making it impossible to unlock the lock mechanism 15.

This invention aims to solve such conventional problems.

In order to achieve the above object, this invention forms protrusions on the case and the button, respectively, and inserts a seal ring between the two protrusions to allow infiltration from between the case and the button. Rather than reliably preventing water, it is important to reduce the infiltration of water into the lock! l.

Embodiments of the present invention will be described below based on the third embodiment.

In addition,#! Components that are the same as those of the conventional example explained in FIG. 1 and FIG.

Button type cylinder lock with IK opening/closing body 5
The case 7 has a mounting hole 3 formed in the outer panel 3.
A case washer 19 and a case cover 17 made of 9K, rubber, synthetic resin, or the like are attached as valves, and an inner end 17a of the case cover 17 is hemmed in a direction perpendicular to the longitudinal direction of the case 7.

Also, on the side wall of the button button 9 that slides inside the case 7, there is a hemmed inner end 17M of the case cover 17.
A seven-lung-shaped protrusion 41 is formed facing the case inner wall 7a, and the button cover 21 is fitted from the protrusion 41 toward the upper end of the button 9. The protruding part 2 is filled with oil on the protruding part 41 of this button cover 21.
1a constitutes a protrusion on the button side.

The inner side 17a of the case cover 17 is made of rubber or a soft synthetic resin material that comes into contact with the flat part of the protrusion 21a of the button cover 21 and seals the case cover 17 and the button cover 21 watertightly. A seal ring 43 is fitted therein.

In this way, by fitting the flat contact surface K between the case cover 17 and the button cover 21 and the seal ring 43, rainwater, car wash water, etc. can be prevented from flowing into the opening and closing body from between the case cover 17 and the button cover 21. 1 Make sure that the internal pressure intrudes W<
It can be prevented.

In the above embodiment, the seal ring 43 is attached to the case side, and in the case cover 17 and the button cover 21 of the button lock 5, the seal ring 43 is attached directly to both the case 7 and the button 9. It is also possible to protrude two integral protrusions so as to face each other, and to interpose a seal ring between the flat surfaces of both protrusions.

In addition, 11 in the figure regulates or allows the sliding of the button 9,
It is a cylinder connected to the locking mechanism 15 of the opening/closing body 1 via the linkage 13, 23 is a shutter provided at the upper end opening of the cylinder 11, and 25 is a shutter cover.

In this invention, a seal ring is inserted between the case and the button, which are attached to the outer panel of the opening/closing body, to seal the gap between the two, as described above, so that rain water and car wash water can be removed more easily than before. The amount of water that has entered the inside of the car body is small, so all the water that has entered the inside of the car body is reliably drained from the water drain hole provided at the lower end of the car body through the water receiving member to the outside of the car.
Since the lock mechanism is exposed to R4, there is no chance of getting the lock mechanism wet or water accumulating on the floor of the vehicle body, and there is no need for anti-rust treatment of the lock mechanism or accuracy control of each part, improving the quality of the vehicle. It has the effect of being able to

Further, since water does not accumulate on the contact surface between the button and the case, or even if it does, the amount is small, the locking mechanism does not become impossible to unlock in cold weather.
