Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closed handle device that locks and locks a door in close contact with a fixed frame body such as a refrigerator body or another door.

[0002]

2. Description of the Related Art In a conventional closed handle device, a tightening nut screwed with a pivot bolt is arranged on the front side of the handle, and even after mounting, the tightening nut is rotated to change the positional relationship between the base and the handle. To adjust the engagement state of the handle and the buckle, and once the assembly is done, the pivot bolts and tightening nuts cannot be rotated, so it is necessary to adjust the positional relationship between the base and the handle. Some use screws and the like.

However, in the former conventional device, the tightening nut gradually loosens while the handle is rotated and used,
Eventually, the nut may fall off.

Further, the latter conventional device has a large number of parts due to its structure, and a welding process for fixing the fastening nut to the base is added, so that the assembling work is complicated and the manufacturing cost is high. Become. Actual Kaisho 63-10177
In the closed handle device described in the publication, the tightening nut fit
The groove type mounting plate for fitting is welded and fixed to the fixed seat.
As a result, the assembly work is complicated and the manufacturing cost is high.
Become

Furthermore, depending on the specific conditions of the shape and structure of the fixed frame, when the receiving plate is separated from the base by a certain distance or more, the engagement length between the tip of the handle and the receiving plate is firmly locked and locked. It will be difficult to secure just the necessary amount.

[0006]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to easily assemble without requiring a complicated welding process , and to prevent the pivot bolt and the tightening nut from coming off due to looseness, and to further improve the base and the handle. It is an object of the present invention to provide a closed handle device that can easily change the positional relationship of the above and can secure a required amount of engagement length between the money receiver and the handle.

Means for Solving the Problems Hereinafter, referring to the attached drawings, a closed handle device of the present invention is provided with a hexagonal recess 15 on a back surface thereof and a through hole 16 at the center of the recess 15. A rectangular base 1 and a rectangular shape in which the base 1 is tightly covered from the front side and a through hole 19 is provided in the center corresponding to the through hole 16 so that the base 1 is non-rotatably restrained.
Of the base cover 4, the handle 3 whose front end engages with the receiving metal 9, and the insertion hole 23 for insertion of the handle 3 in the transverse direction, and the through hole 17 is provided corresponding to the through hole 19 of the base cover 4. It has a handle holder 2.

Furthermore, in this closed handle device, the hexagonal head portion 6a is non-rotatably fitted in the hexagonal recessed portion 15 of the base 1, and the through hole 16 of the base 1, the through hole 19 of the base cover 4 and the handle holder 2 are provided. Tightening to fasten the handle holder 2 to the base 1 and the base cover 4 via the washer 5, which is screwed to the pivot bolt 6 inserted into the through hole 17 of the handle 3 and the through hole 18 of the handle 3. It has a nut 7 and a nut fixing screw 8 which is screwed into the side surface hole 24 of the tightening nut 7 and fastened to the side surface of the pivot bolt 6.

A plurality of through holes 18 of the handle 3 can be arranged side by side along the length direction of the handle 3, and an appropriate one can be selected according to the positional relationship between the receiving metal 9 and the base 1. The pivot bolt 6 is inserted.

[0010]

In this closed handle device, the door 13 is locked and locked in the fixed frame body 14 in a closed state by tightly engaging the tip 9 of the handle 3 with the receiving plate 9 fixed to the fixed frame body 14. . Base the handle 3 around the pivot bolt 6
When it is rotated by a predetermined angle with respect to, the engagement between the receiving portion 9 and the handle 3 is released, and the door 13 is opened by pulling the handle 3.

If the handle 3 and the receiving member 9 are loosened due to the improper installation or wear of the receiving member 9 or the handle 3 and the close engagement between the two is not established, the nut fixing screw 8 is used. After loosening, the tightening nut 7 is tightened to remove the deviation and looseness, and then the nut fixing screw 8 is tightened again to make the tightening nut 7 unrotatable.

[0012]

Embodiment In the illustrated embodiment, the base 1 and the base cover 4 are provided with a through hole 21 of the base cover 4, a screw 11 inserted through the through hole 20 of the base 1 from the front side, and a nut 22 screwed to the screw 11. The door 13 is integrally fastened and fixed. Since the hexagonal recess 15 of the base 1 is closed by the front portion of the door 13, the pivot bolt 6 does not fall off the base 1 even if the tightening nut 7 is removed.

The money receiving 9 and the money receiving cover 10 are the money receiving cover 1
The screw 12 and the nut 27 passing through the through hole 26 of 0 and the through hole 25 of the receiving member 9 are integrally fastened and fixed to the fixed frame body 14. Two through holes 18 of the handle 3 are arranged side by side.

The handle holder 2 is made of Duracon resin, and the rotational resistance of the handle 3 is adjusted by increasing or decreasing the amount of tightening by the tightening nut 7. The tightening nut 7 is a cap nut having a sufficient adjustment allowance.

[0015]

As described above, in the closed handle device of the present invention, the hexagonal head 6a of the pivot bolt 6 is fitted into the hexagonal recess 15 of the base 1, and the through hole 16 of the base 1 and the through hole of the base cover 4 are inserted. A tightening nut 7 is screwed into the tip of the pivot bolt 6 inserted through the hole 19, the through hole 17 of the handle holder 2 and the through hole 18 of the handle 3, and the side hole 2 of the tightening nut 7 is inserted.
Since the nut fixing screw 8 screwed in from 4 is fastened to the side surface of the pivot bolt 6, the tightening nut 7 and the pivot bolt 6 do not loosen and fall off.

Furthermore a sealed handle assembly of the present invention, rectangular
Do not rotate the rectangular base 1 inside the shaped base cover 4.
Since the hexagonal head 6a of the pivot bolt 6 is non-rotatably fitted into the hexagonal recess 15 of the base 1, the pivot bolt 6 is non-rotatably assembled to the base 1 . No complicated welding process is included
Simplifies the manufacturing and assembly process and reduces manufacturing costs.
It is possible that.

A plurality of through holes 18 of the handle 3 are arranged side by side along the length direction of the handle 3, and one through hole 18 selected according to the concrete condition of the shape and structure of the fixed frame is pivoted into one through hole 18. By inserting the bolt 6, the engagement length between the handle 3 and the receiving metal 9 can be accurately secured by a necessary and sufficient amount,
As a result, the door 13 can be firmly closed and closed with respect to the fixed frame body 14.
