Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a vehicle cylinder key used to lock a door of a vehicle.

[0002]

[Prior Art]

 Generally, a cylinder key for a vehicle is a cylinder body that includes a key body that includes a key cylinder that is mounted to penetrate a vehicle door outer plate, a front end of the key cylinder that is closed, and that is mounted across the key cylinder and the door outer plate. Made of plates and. The cylinder plate is packed to prevent water from entering between it and the door skin.

However, when the vehicle is used in a cold region, if water adheres to the front end of the key cylinder and the cylinder plate around it, or if water enters the key cylinder from between the cylinder plate and the key cylinder and freezes. , It becomes difficult to unlock. In the past, when the cylinder plate or key cylinder was frozen in this way, it was thawed by pouring hot water onto the cylinder plate or by exposing it to the light of a lighter, but this method may damage the door outer plate. Yes, and it took a long time to thaw and the door could not be opened immediately.

Therefore, the applicant has previously provided an electric heater and a thermostat in the vicinity of the key cylinder, and the electric circuit thereof is driven by a switch that is closed by inserting the door key or operating the door handle. Has proposed a key cylinder deicing device for defrosting (see Japanese Utility Model Laid-Open No. 58-111761).

[0005]

[Problems to be solved by the device]

 However, since this device energizes the electric heating heater to thaw the ice after inserting the door key or operating the door handle, it takes time for the electric heater to rise after energization, and it takes time for the key cylinder to thaw. Therefore, the door cannot be unlocked immediately, and when the door key insertion opening or the door handle freezes, the key cylinder cannot be thawed.

An object of the present invention is to avoid the above-mentioned drawbacks, prevent the key cylinder and the cylinder plate itself from freezing, and open the door immediately without damaging the vehicle door outer plate. To provide a cylinder key for a vehicle.

[0007]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention closes a key body including a key cylinder penetratingly mounted on a vehicle door outer plate, a front end of the key cylinder, and straddles the key cylinder and the door outer plate. A cylinder key for a vehicle, which comprises a cylinder plate to be attached to a cylinder plate, is provided with an antifreezing portion formed by flocking and water-repellent treatment on the surface of the cylinder plate. .

[0008]

[Action]

 If the surface of the cylinder plate of the cylinder key is provided with antifreeze parts that are formed by bristling and water repellent treatment, the water adhering to the cylinder plate will be repelled and water will enter the key cylinder. Since it does not exist, it is possible to prevent the key cylinder from freezing. Therefore, the unlocking of the cylinder key can be performed immediately and easily without the need to perform the deicing operation.

【Example】

 Referring to the drawings, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a vehicle door 12 having a vehicle cylinder key 10 according to the present invention. It is attached to the outer plate 14 directly below the door knob 16.

As shown in FIGS. 2 and 3, the cylinder key 10 includes a key body 20 including a key cylinder 18 that is mounted to penetrate a vehicle door outer plate 14, and a key cylinder 20 that closes a front end of the key cylinder 18. It is composed of a key cylinder 18 and a cylinder plate 22 which is attached across the door outer plate 14. The key body 20 includes a rotor 24 provided in the key cylinder 18 and a lever 26 attached to the rotor 24 to open and close the lock. In FIG. 2, reference numeral 28 is a key inserted into the key body 20 through the key hole 22a.

The vehicle cylinder key 10 of the present invention, as shown in an enlarged view in FIG. 4, further includes an antifreezing portion 30 formed on the surface of the cylinder plate 22 by bristling and water repellent treatment. Although the cylinder plate 22 is made of a metal plate, the antifreezing portion 30 may be formed by directly flocking the cylinder plate 22 using a known flocking technique, or by attaching a pre-flocked plastic film. The cylinder plate 22 may be attached to the key cylinder 18 and caulked. The water repellent treatment is performed by spraying or applying a fluorine-based water repellent to the planted flock.

As described above, the antifreezing portion 28 formed by flocking water on the surface of the cylinder plate 22 of the cylinder key 10 and water-repellent treatment repels water attached to the cylinder plate 22 by the water-repellent flocking. Therefore, water can be prevented from entering the key cylinder 18, so that the key cylinder 18 and the cylinder plate 22 can be prevented from freezing.

Therefore, the cylinder key 10 can be immediately unlocked without applying hot water to the cylinder plate 22 or exposing the writer to fire. Moreover, since the key cylinder 18 and the cylinder plate itself do not freeze, the thaw device is not required.

[0014]

[Effect of the device]

 According to the present invention, as described above, the freezing prevention portion on the cylinder plate can prevent the key cylinder and the cylinder plate from freezing, so that the cylinder plate can be heated with hot water or exposed to the lighter's fire. In addition, the cylinder key can be immediately unlocked without damaging the door outer plate, and an ice thawing device is not required, which is economical.
