Description

[Detailed Description of the Invention] The present invention relates to a door handle device.

In conventional doors, handle device layouts as shown in FIGS. 2 to 4 are common. That is, in FIG. 2, an embossed recess 2 is formed in the door outer panel 1, a door opening handle 3 is arranged in this recess 2, and a cylinder lock for locking and unlocking a door lock (not shown) is provided diagonally below the handle 3. 4 is arranged, and the key insertion head 4a of the cylinder lock 4 is exposed externally. In FIG. 3, a handle 3 and a cylinder lock 4 are arranged side by side and surrounded by an escutcheon 5, and in this case as well, the key insertion head 4a of the cylinder lock 4 is exposed. In FIG. 4, the handle 3 is fixed to the door outer panel 1 and functions only as a grip, and the push-button cylinder lock 4 locks/unlocks and opens the door.
A cylinder lock 4 is arranged close to the front of the handle 3, and the head 4a of the cylinder lock 4 is also exposed externally.

As described above, since the head 4a of the cylinder lock 4 is exposed to the outside in both cases, water can enter the cylinder lock 4 through the head 4a during car washing or rain, causing freezing, especially in cold regions, and causing the key plate to deteriorate. The problem arises that it becomes impossible to insert the . In addition, an increase in the amount of water entering the door due to water entering directly from the head 4a of the cylinder lock 4 may wet parts inside the door, such as the door window regulator, etc.
This also increases water intrusion into the joints between the inner and outer panels of the door, which is also unfavorable in terms of rust prevention. Note that a shutter 4c is attached to the back side of the key insertion hole 4b of the cylinder lock head 4a to prevent water from entering, and the shutter 4c is rotated when the key is inserted into the hole 4b.
The reality is that this shutter 4c opens under the pressure of water from the car wash nozzle and allows water to enter, so that no fundamental measure has been taken to prevent water from entering. Further, since the cylinder lock 4 is always exposed externally, it may become an obstacle to improving the external appearance quality and design, and there is also the problem that the degree of freedom in shaping is limited.

The present invention was developed in view of the conventional situation, and it solves the above problems while ensuring operability of opening the door by covering the cylinder lock with the handle of the door opening handle. The purpose of the present invention is to provide a handle device that is effective in terms of freedom of design.

The present invention will be described below based on an embodiment. In FIGS. 5 and 6, a door opening handle 3 is housed in an embossed recess 2 formed in a door outer panel 1 in a non-operating state, and when the door is opened. The handle portion 3a is pulled out from the embossed recess 2 to open the door. A cylinder lock 4 for locking and unlocking a door lock (not shown) is attached to the end of the embossed recess 2 via a clip 10, and its head 4a is attached to the handle 3 when the handle 3 is not operated.
covered by the end of a.

More specifically, the axis θ ₁ of the cylinder lock 4 is diagonally downward with respect to the door outer panel 1, and when the key is inserted, the key 12 is in the position shown by the imaginary line in FIG. And the handle 3a of the handle 3
In the non-operating state, the cylinder is in the position indicated by the solid line in FIGS. 5 and 6, and its height H ₀ completely overlaps the height H ₁ of the cylinder lock head 4a. That is, the handle 3a prevents the key 12 from being inserted into the cylinder lock 4 when the handle 3a is not operated.
The handle 3a is designed to open the door by pulling it up to position A shown by the imaginary line, and at position B, which is the imaginary line during the opening operation before the door opening operation, the cylinder of the key 12 is pressed. It is designed to allow insertion into lock 4.

With this structure, since the head 4a of the cylinder lock 4 is covered when the handle 3 is not operated, direct impact of car wash water and rainwater on the head 4a is avoided, and intrusion into the cylinder lock 4 is significantly reduced. Therefore, water intrusion into the cylinder lock 4 is suppressed, the door internal parts are less wetted, the durability of the door internal parts is improved, and rusting is also suppressed.

Even in cold regions, less water freezes, so it is no longer impossible to insert the key.
Also, since the cylinder lock is not exposed externally,
The degree of freedom in design and appearance quality can be increased.

Furthermore, when opening the door after unlocking it from the locked/closed state, first pull up the handle 3a from the solid line position in Figure 6 to position B, insert the key 12 to unlock, and then move the handle 3a all the way to position A. The door can be opened by pulling it up. Therefore, compared to the conventional method of unlocking the door with a key and then operating the handle to open the door, not only can better operability be ensured, but the door can be opened with a series of operations. It is easier to operate than before.

As shown in Fig. 7, a seal rubber 14 is provided on the back surface of the handle 3a at a portion corresponding to the head 4a of the cylinder lock 4, and if the rubber seal 14 comes into contact with the head 4a when the handle is not operated, water from the head 4a will be removed. can prevent the intrusion of In the example shown in FIG. 7, not only can water intrusion be suppressed by the handle 3a, but also water intrusion itself is prevented by the seal rubber 14, which prevents the parts inside the door from getting wet compared to the embodiments shown in FIGS. 5 and 6. This has the advantage that rust can be more reliably prevented.

As is clear from the above embodiments, according to the present invention, while ensuring operability of opening the door with the handle,
It prevents water from entering the door from the cylinder lock, solving the problem of not being able to insert the key due to freezing of the cylinder, increasing the durability of the parts by preventing the parts inside the door from getting wet, and preventing rust from forming on the door joints. This has great practical effects in that it can significantly reduce the number of particles and also expand the degree of freedom in shaping.

Claims (1)

[Scope of utility model registration request] A door opening handle and a cylinder lock for rotating and unlocking the door lock are respectively installed on the outer panel of the door, and when the handle is not operated, the handle portion of the handle covers the head of the cylinder lock so that the key cannot be inserted into the cylinder lock. The door handle device is further characterized in that, when the handle is in the middle of opening the door, the head is exposed from the handle portion to allow insertion of a key.
