BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle for a waterproof door used in a switchboard storage box or the like.

[0002]

2. Description of the Related Art In a conventional waterproof door handle device, a water impermeable cover is fitted from the back side to the entire casing which is fitted into the mounting hole of the door from the front side, and a front end portion of the water impermeable cover is fitted. A flange portion was provided all around, and the flange portion of the impermeable cover was fastened between the front flange portion of the casing and the entire surface of the door.

However, since the water-impermeable cover as the waterproof member is fitted to the main body of the casing, it may fall off or be lost during installation and removal at the site.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a handle device for a waterproof type door, in which there is no need to attach or remove a waterproof member in the field, so that there is no risk of the waterproof member falling off. Is.

[0005]

[MEANS FOR SOLVING THE PROBLEMS] A waterproof door handle device of the present invention will be described below with reference to the reference numerals in the accompanying drawings. In a casing 3 that is fitted into a mounting hole 15 of a door 7 from the front side, The film 1 is attached from the back side or formed integrally with the casing 3, and the flange part 16 of the packing film 1 is tightened between the front end flange part 4 of the casing 3 and the front surface 7a of the door 7.

In this waterproof door handle device, the flange portion 16 of the packing film is brought into close contact with the front surface of the door 7 so that the material 1 closes the mounting hole 15 locking hole 10 of the door 7 and locks rainwater or the like. Prevents entry into the inside of the door 7 through the stop hole 10.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the embodiment shown in FIGS. 1 to 4, a shaft cylinder portion 5 into which a locking shaft 20 is fitted is provided at a base end portion of a casing 3, and a casing 3 has a distal end portion. A lock housing portion 9 and a lock hole 11 communicating with the lock housing portion 9 are provided. On the front side of the casing 3, there is provided a front recess 6 in which a handle 17 is retractably housed.

Since the packing film 1 is attached to the entire back surface of the casing 3 or integrally formed, rainwater and the like can be prevented from entering through the lock holes 11. An escape hole portion 13 for a screw hole 12 for fixing to the door 7 is provided at the center of the back surface of the packing film 1. At the rear end of the back surface of the packing film 1, an escape hole 14 for the shaft cylinder 5 is provided. The screw hole 12 does not penetrate the front concave portion 6 of the casing 3, but the shaft cylinder portion 5 penetrates the front concave portion 6. Therefore, an O-ring 8 is inserted as a waterproof member between the shaft tube portion 5 and the locking shaft 20.

As shown in FIG. 7, instead of the O-ring 8, the packing film 1 is extended to form an annular rib portion 23 inside the bearing cylinder 5, and the annular rib portion 23 is attached to the locking shaft 20. It can also be closely attached and waterproofed. The handle 17 has a base end pivotally attached to a pivot bearing 21 of a locking shaft 20 by a pivot 19, a finger hook projection 22 is provided on the front surface of the base end, and a coil spring 18 is fitted in the pivot bearing 21.

In another embodiment shown in FIGS. 5 and 6, the packing film 1 is provided only on the flange portion 4 of the casing 3.

[0011]

As described above, in the waterproof door handle device of the present invention, the casing 3 fitted into the mounting hole 15 of the door 7 from the front side has the packing film 1 bonded from the back side as a waterproof member. Since it is molded integrally with 3, there is no risk of falling off or loss of the waterproof part due to on-site installation or removal.
