Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat handle with a lock mechanism attached to a door such as a box for storing electrical equipment.

[0002]

2. Description of the Related Art A conventional flat handle of this type has a cylinder lock for locking the rotation of a shaft provided with a locking plate, as disclosed in Japanese Utility Model Publication No. 3-19249 filed by the present applicant. It was mounted inside the main body, and the structure was such that the surface of this cylinder lock was always covered with a flat plate-shaped handle. However, this conventional flat handle has a drawback that the lock cannot be confirmed unless the handle is pulled up because the flat handle covers the surface of the cylinder lock.

There is also known a flat handle having a structure in which a key insertion hole is formed in a flat plate-like handle which covers the surface of a cylinder lock, and locking can be confirmed with the handle closed. With such a structure, the surface of the cylinder lock is always exposed on the surface of the handle through the key insertion hole,
The aesthetics of the handle is impaired, and dust and rainwater may enter the inside of the cylinder lock.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, allows the locking to be confirmed from the outside, does not impair the aesthetics of the handle, and allows dust and rainwater to enter the inside of the cylinder lock. It was made to provide a difficult flat handle.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and a hooking lever for locking the lower end of a handle attached to a shaft is provided with a sub-concave below the main body. And a cylinder lock for locking the hooking lever is installed in the sub-concave so as to be located rearward away from the key insertion hole provided in the hooking lever. It is characterized by.

[0006]

In order to lock this flat handle, first, the handle attached to the shaft so that it can be raised and lowered is stored in the recess provided in the front surface of the main body, the lower end of the handle is locked to the catch lever, and then the catch lever is locked. The cylinder lock may be locked by the key inserted through the key insertion hole. In this state, the surface of the cylinder lock can be seen through the key insertion hole,
The locked state can be confirmed. Also this cylinder
-Since the lock is installed with a gap so that it is located rearward away from the key insertion hole, even if rainwater etc. penetrates into the inside from the key insertion hole, it will not reach the keyhole, and the cylinder lock will not be exposed to rainwater etc. It will not be adversely affected.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings. Reference numeral 1 denotes a vertically long main body fixed to a door of a box or the like. The main body 1 has a shallow concave portion 2 for storing a handle on a front surface thereof, and a bearing portion 3 protruding from the upper rear portion of the concave portion 2. There is. Reference numeral 4 is a shaft of a handle rotatably supported by the bearing portion 3, and a locking plate 5 is attached to the rear portion thereof. Reference numeral 6 denotes a flat plate-like handle which is supported on the front side of the shaft 4 so as to be freely undulated and is housed in the recess 2 when not in use.

Reference numeral 7 denotes a screw coil spring for automatically causing the handle 6 when the handle 6 is rotated, and 8 stores the handle 6 in the recess 2 against the elastic force of the screw coil spring 7. , A hooking lever that locks the lower end of the handle 6. The hooking lever 8 is provided in a sub-recessed portion 9 that is continuously provided below the recessed portion 2 of the main body 1, and the front surface of the sub-recessed portion 9 is covered with the hooking lever 8. This hooking lever 8 is pivotally supported on the side plate portion of the main body 1 by means of pins 10 on both sides of the upper part, and the hooking portion 12 formed on the upper end of the hooking lever 8 is attached to the handle 6 by the elasticity of the screw coil spring 11 attached to the pin 10. The handle 6 is housed and retained in the recess 2 by being engaged with the lower end.

Reference numeral 13 is a cylinder lock for locking the catch lever 8. The cylinder lock 13 is attached to the sub-recess 9 of the main body 1 with a gap 17 so that the front surface of the cylinder lock 13 is located rearward of the key insertion hole 14 of the hooking lever 8 and enters from the key insertion hole 14. Rainwater or the like flows down from the gap 17 and does not reach the key hole of the cylinder lock 13. Further, the cylinder lock 13 is rotated by the key inserted through the key insertion hole 14, and the protrusion 15 provided on the cylinder lock 13 is brought into contact with the lock portion 16 provided on the hook lever 8 so that the hook lever 8 of FIG. It is supposed to be locked so that it cannot rotate counterclockwise.

With this construction, the handle 6 is provided in the shallow recess 2 for storing the handle provided on the front surface of the main body 1 when the handle 6 is locked.
And the lower end of the handle 6 is locked by the hooking lever 8 against the screw coil spring 7 and the hooking lever 8 is locked by the cylinder lock 13 to prevent the locking plate 5 from rotating. Also, when unlocked, the key insertion hole 14
The cylinder lock 13 is operated to release the lock of the catch lever 8, and the lower part of the catch lever 8 is pushed toward the main body side to release the hook part 12 above the catch lever 8 from the lower end of the handle 6. Then, the handle 6 is raised by the torsion coil spring 7, and then the handle 6 is rotated to unlock the locking plate 5 attached to the rear end of the shaft 4.

Further, in the present invention, the cylinder lock 13 for locking the hooking lever 8 is mounted so as to be located behind the key insertion hole 14 of the hooking lever 8,
The surface of the cylinder lock 13 can be seen through the key insertion hole 14, and the locked state can be confirmed from the outside. Further, the cylinder lock 13 has a gap 1 between it and the key insertion hole 14.
Since 7 is installed and attached, rainwater etc. can be inserted into the key insertion hole 14
Even if it intrudes from above, it is discharged downward from this gap 17, and the cylinder lock 13 is not adversely affected by rainwater.

[0012]

As is apparent from the above description, the present invention makes it possible to confirm the locked state from the key insertion hole, and since the handle does not have the key insertion hole, it does not spoil the aesthetics of the handle and is a cylinder lock. Will not be adversely affected by rainwater. Therefore, the present invention greatly contributes to the industry by solving the problem of the conventional flat handle.
