DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a lock cap for protecting a keyhole from rainwater and dust.

[0002]

2. Description of the Related Art A conventional lock cap for protecting a key hole from rainwater and dust is provided so that the key hole can be opened and exposed at the time of locking or unlocking, and the key hole is closed at a normal time. There is known an embodiment provided with a cover pivotally supported so that the cover can be opened and closed.

[0003]

However, in the above-mentioned conventional lock cap, although the key hole can be protected from rainwater and dust, the cover is simply supported by the cover so as to be freely opened and closed. However, the cover was not always kept open or closed. Therefore, when actually performing the locking or unlocking operation, the cover must be locked and unlocked with the other hand while keeping the cover open with one hand. Operationally inconvenient.

The present invention has been made in view of the above-mentioned conventional drawbacks to solve the above-mentioned drawbacks. The purpose of the present invention is to protect a key hole from rainwater and dust, and to perform a locking operation and an unlocking operation. An object of the present invention is to provide a lock cap that can easily perform those operations with one hand.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned object, and has as its gist a cover for exposing a keyhole by an opening operation and covering the keyhole by a closing operation; A cover support means for pivotally supporting the cover with respect to the key hole, and further exposing the key hole in conjunction with the opening operation of the cover and covering the key hole in conjunction with the closing operation of the cover; The lock cap comprises: a shutter that locks the shutter; and a shutter shaft means for pivotally supporting one end of the shutter in the cover.

According to this aspect, the key hole is exposed and the cover is interlocked with the closing operation of the cover in conjunction with the opening or closing operation of the cover pivotally supported by the cover supporting means in the lock cap. Since the shutter for covering the key hole and the shutter support means for pivotally supporting one end of the key hole in the cover are provided, the key hole can be reliably protected from rainwater and dust.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a lock cap according to the present invention,
The above-mentioned cover is pivotally supported by the cover shaft means so as to be openable and closable with respect to the key hole, and is disposed so as to be opened so as to expose the key hole or closed so as to cover the key hole. The keyhole is protected from rainwater and dust.

Further, the cover is maintained in each state by the flexible cover latching means when the key hole is exposed when the opening operation is performed and when the key hole is covered when the closing operation is performed. ing. The material and the like of the flexible cover hooking means are not particularly limited, and any material can be used as needed as long as the material can exhibit flexibility.

Further, the shutter is pivotally supported on the cover by shutter support means, and is arranged so as to expose the keyhole in conjunction with the opening operation of the cover and cover the keyhole in conjunction with the closing operation of the cover. Is established,
The keyhole is more reliably protected from rainwater and dust. The shutter may be provided with guide means such as a guide rail, a guide groove, and a guide piece to enable smooth sliding.

Embodiments of the present invention will be described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
Here, FIG. 1 is a schematic perspective view showing one embodiment of the present invention. FIG. 2A is an enlarged schematic cross-sectional view showing a state in which the cover of FIG. 1 is closed, and FIG. 2B is a schematic cross-sectional view showing an enlarged state of opening the cover in FIG. FIG.

A door handle (handle) 10 shown in FIG.
Are a handle base 11 for fixing the door handle 10 to a door (not shown), and a grip (handle grip) for controlling opening and closing of a rod (not shown) when opening and closing the door and opening and closing the door. The main part is constituted by a part) 12, a locking mechanism 13 for locking the door in a closed state, and a lock cap 14 for protecting the key hole 13a of the locking mechanism 13 from rainwater and dust.

The handle base 11 is fixed to a door by bolts and nuts, and a locking mechanism 13 is provided at a central portion thereof.

The grip 12 for opening and closing the door is equivalent to a grip portion pivotally supported so as to be pivotally operable, and enables the control of the insertion and removal of the rod when the door is opened and closed.

The locking mechanism 13 for locking the closed state of the door is provided with a key hole 13a for inserting a key when locking or unlocking, and a rod or the like (shown in FIG. Zu).

The lock cap 14 for protecting the key hole 13a of the locking mechanism 13 from rainwater or dust exposes the key hole 13a of the locking mechanism 13 by opening operation and closes the key hole of the locking mechanism 13 by closing operation. A cover 14a for covering the cover 13a, a cover support shaft 14b for pivotally supporting the cover 14a, and a plastic cover functioning as a flexible cover locking means for maintaining the cover 14a in an open state and a closed state. A cover hook 14c, a shutter 14d for exposing or covering the key hole 13a of the locking mechanism 13 in conjunction with the opening and closing operation of the cover 14a, and a shutter spindle for supporting one end of the shutter 14d to the cover 14a. A portion 14e.

Further, the cover support shaft portion 14b has the first surface portion 14b1 with which the cover hooking piece 14c abuts in a press-contact state when the key hole 13a is covered when the cover 14a is closed, and the cover 14a is opened. When the key hole 13a is exposed at this time, the cover hooking piece 14c abuts in the pressed state when the cover hooking piece 14c comes into contact with the cover hooking piece 14c while the cover 14a is being closed or opened. And a slightly rounded corner portion 14b3 which abuts while sliding.

As shown in FIG. 2A, the lock cap 14 employed in the door handle 10 has a cover hook 14 when the key hole 13a is closed.
c is in contact with the first surface portion 14b1 of the cover support shaft portion 14b in a press-contact state, and the cover 14a is kept in this state unless manual external force is applied manually. On the other hand, when a manual external force is applied to the lock cap 14 to open the cover 14a by manpower, the cover 14a moves along the corner portion 14b3 due to its flexibility as shown in FIG. 2 (b). After being expanded flexibly and slid in the pressed state and the bent state, the cover 1
When the cover 4a is fully (maximally) opened, the cover hooking piece 14c engages with the second surface portion 14 of the cover support shaft 14b.
The cover 14a is in contact with the cover 14a in a pressure-contact state along b2, and the cover 14a is maintained in this state unless manual external force is applied by human power.

The shutter 14d for exposing or covering the key hole 13a of the locking mechanism 13 in conjunction with the opening and closing operation of the cover 14a has one end piece of the shutter shaft 1
4e, the cover 1a is supported by the cover 14a.
4a has an opening 14d1 for exposing the keyhole 13a when the opening operation is performed. The shutter 14d
Guide means (guide rails, guide grooves, guide pieces, etc.), not shown, can be provided in order to enable smooth sliding.

As described above, in the embodiment described above, the key hole 13a of the locking mechanism 13 is covered and protected by the cover 14a, and is further covered by the shutter 14d to be protected more securely.

[0020]

According to the present invention, the key hole is exposed in conjunction with the opening or closing operation of the cover pivotally supported by the cover supporting means in the lock cap, or the key is opened in conjunction with the closing operation of the cover. Since the mode in which the shutter for covering the hole and the shutter support means for supporting one end of the hole in the cover are provided is adopted, a remarkable effect is obtained in that the key hole can be more reliably protected from rainwater and dust.
