Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a handle device that locks and locks a door in close contact with a fixed frame such as a refrigerator body or another door.

(Prior art) In a conventional sealed handle device, a tightening nut screwed onto a pivot bolt is placed on the front side of the handle body, and even after installation, the tightening nut is turned to connect the fixed seat and the handle body. One is that the positional relationship can be changed to adjust the engagement state of the handle body and the receiving part, and the other is that the position of the fixed catch and the handle body is changed because the pivot bolt and tightening nut cannot be rotated once assembled. There are some relationships that cannot be changed.

(Problem that the invention aims to solve) However, with the former device, there is a risk that the tightening nut may loosen and fall off during use, and with the latter device, due to an error in design and construction, the tightening nut may loosen and fall off. If the engagement between the parts is not tight from the beginning, or if the engagement becomes loose during use, it will not be able to function as a sealed handle device.

Therefore, an object of the present invention is to provide a closed handle device that can accurately adjust the position of the handle body so that it tightly engages with the receiving part even when the pivot bolt and nut are fixed to prevent them from falling off. It is to provide.

(Means for Solving the Problems) As explained below using reference numerals in the attached drawings, the closed handle device of the present invention includes a fixed seat 1,
a handle body 2 which is pivotally attached to the front side of the fixed seat 1 by a pivot bolt 4 and engages with a receiving part 20;
disposed between the handle body 2 and the fixed seat 1,
The fixed seat 1 consists of a movable seat 3 that rotates integrally with the handle body 2, and a rotation angle regulating plate 5 that is accommodated in the movable seat 3 and rotates integrally with the handle body 2.
The nut 7 screwed onto the pivot bolt 4 is fixed non-rotatably on the back side of the rotation angle regulating plate 5 and the fixed catch 1.
Insert the washer 8 between them, screw the adjusting screw 10 into the screw hole 13a passing through the handle body 2, and insert the tip of the adjusting screw 10 inserted into the receiving hole 13b passing through the movable seat 3 at the rotation angle. It is brought into contact with the regulating plate 5 in front.

(Function) In this sealed handle device, the fixed catch 1 is fixed to the door 22 through the mounting hole 6, and the handle body 2 is fixed to the door 22 through the mounting hole 6.
By tightly engaging the front end portion 2b with the fixed frame 21 or the receiving portion 20 on the other door side, the door is locked in an airtight state. When the handle body 2 is rotated by a predetermined angle, the engagement between the receiving portion 20 and the handle body 2 is released, and the door 22 is opened by pulling the handle body 2.

If looseness occurs between the handle body 2 and the receiver 20 due to incorrect installation or wear of the receiver 20 or the handle body 2, and the tight engagement between the two is not established, the adjustment screw 10 Rotate to move the handle body 2 away from the fixed catch 1,
Absorbs or compensates for the loosening or gap.

(Embodiment) In the illustrated embodiment, the handle body 2 consists of a gripping part 2a, a tip part 2b that engages with the receiving part 20, and an intermediate part 2c provided with a shaft hole 12. The pivot bolt 4 is fitted into a receiving groove 11 formed in the movable seat 3 and inserted into the shaft hole 12 .
Washer 8 between rotation angle regulating plate 5 and fixed catch 1
is made of a stretchable resin material, and a similar resin washer 9 is inserted between the head of the pivot bolt 4 and the handle body 2.

The screw hole 13a is located in the middle part 2 of the handle body 2.
Two movable seats 3 are provided at c with the shaft hole 12 in between.
is provided through a receiving hole 13b that communicates with the screw hole 13a. The receiving hole 13b is formed of a screw hole or a simple through hole. The head of the adjusting screw 10 is provided with a hexagonal hole 14 for rotational operation.

The disc-shaped rotation angle regulating plate 5 is fitted into a recessed portion on the back surface of the movable seat 3, and the protrusion 1 on the inner wall surface of the movable seat 3
5, it is connected and fixed to the movable catch 3. A stopper pin 17 protruding from the front of the fixed catch 1
passes through the washer 8 and reaches the arc-shaped notch 16 of the rotation angle regulating plate 5. The stopper pin 17 restricts the rotation of the handle body 2 to a constant angle by coming into contact with each end surface of the notch 16.

A groove-shaped mounting plate 19 into which a metal washer 18 and a nut 7 are fitted is fitted into the pivot bolt 4 protruding from the back of the fixed seat 1, and by turning the nut 7, the handle body 2 is attached to the fixed seat 1 side. After proper tightening, the grooved mounting plate 19 is welded and fixed to the stationary seat 1, and the nut 7 is welded and fixed to the pivot bolt 4.
Since this nut 7 is prevented from rotating by the pair of side wall plate portions of the groove-shaped mounting plate 19, the pivot bolt 4 will not loosen and fall off.

(Effects of the invention) As described above, the sealed handle device of the present invention has
A washer 8 is inserted between the rotation angle regulation 5 housed in the movable seat 3 and the fixed seat 1, and an adjustment screw 10 is screwed into the screw hole 13a passing through the handle body 2, passing through the movable seat 3. Since the tip of the adjusting screw 10 inserted through the receiving hole 13b is brought into contact with the rotation angle regulating plate 5, the mounting position of the handle body 1 and the receiving part 20 is adjusted, and the nut screwed onto the pivot bolt 4 is adjusted. 7 is fixed to the fixed catch 1, loosening occurs between the handle body 2 and the receiving part 20 due to improper installation or wear of the receiving part 20 or the handle body 1, and the two become tightly engaged. If the adjustment screw 10 is pressed against the rotation angle regulating plate 5 and rotated, the loosening can be immediately absorbed and adjusted, and a good adhesion state can be maintained. Can always be secured.

Further, the adjustment screw 10 is connected to the rotation angle regulating plate 5.
Since the washer 8 is pressed through the washer 8, the washer 8 is almost evenly pressured over the entire surface of the fixed catch seat 1.
As a result, the washer 8 will not be locally worn or rattled.
