Description

[Detailed description of the invention] [Field of industrial application] The present invention is a handle used for refrigerator doors, etc., which is equipped with an internal opening mechanism that allows the door to be opened from inside the door by pushing a push rod. It is related to the device.

[Conventional technology]

Some conventional refrigerator door handles were equipped with an internal opening mechanism, but the position of the latch and the pivot of the operating handle was far away, and the contact position of the push rod and the operating handle was not appropriate, so it was difficult to push. The operating force when pushing the stick was large.

[Problem that the invention attempts to solve]

Therefore, an object of the present invention is to provide a handle device for a door such as a refrigerator that requires less force to push the push rod when opening the door from inside the door, and allows the door to be easily exited from the door. be.

[Means for solving problems]

The door handle device of the present invention will be explained below using the reference numerals in the attached drawings. a latch 7 which is attached by a pivot 5 to the holder body 2 and engages with and disengages from the receiving rod 6 of the receiving body 2;
It is attached to the main body case 4 by a pivot 8 that is parallel to the pivot 5 and is largely deviated toward the latch 7,
An operation handle 9 having a double structure of an outer member 9a and an inner member 9b, the inner member b and the main body case 4.
A compression coil spring 10 inserted between the inner wall surface of
, a lock 11 that controls the movement of only the outer member 9a, a spring receiver 12 provided on the inner wall surface of the main body case 4 on the opposite side of the pivot 8 with respect to the pivot 5, and a latch inside the pivot 5. A compression coil spring 1 inserted between the end portion 7a and the spring receiving portion 12
3, a mounting member 14 that contacts the right end of the operating handle 9 and is attached to the main body case 4, and a guide tube 16 that is screwed into the screw hole 15 provided in the mounting member 14 from the back of the main body case 4. and a push rod 17 inserted into the guide tube 16, and a pivot 8 of the inner member 9b of the operating handle 9.
The inner end 9c of the inner member located further inside is brought into contact with the latch inner end 7a, and the tip 1 of the push rod 17 is pressed.
7a is brought into contact with the inner member 9b through a small hole 18 provided at the right end of the outer member 9a,
This is to release the engagement between the latch 7 and the receiving rod 6.

[Effect]

In this door handle device, by pushing the operating handle 9 protruding from the main body case 4 into the main body case, the operating handle 9 rotates clockwise about the pivot 8, and accordingly, the operating handle 9 Push the latch inner end 7a that the inner member inner end 9c of the compression coil spring 1 is in contact with.
3, the latch 7 rotates clockwise about the pivot 5, disengaging from the receiving rod 6 of the receiving body 2, and opening the door 3.

On the other hand, by locking the lock 11, the protrusion 19 provided on the rotor of the lock 11 rotates and comes into contact with the right end 9d of the outer member of the operating handle 9. This prevents the door from being pushed into the main body case 4, making it impossible to open the door 3 from the outside.

However, when opening the door from inside the door, since the operating handle 9 has a double structure, the outer member 9
Even if the movement of a is controlled by the lock 11,
By pushing the push rod 17, the tip 17a of the push rod 17 passes through the small hole 18 provided at the right end of the outer member 9a, pushes the inner member 9b, and rotates around the pivot 8. The inner member 9b rotates in the clockwise direction. Along with this, the inner end 9c of the inner member of the operating handle 9 is brought into contact with the inner end 7a of the latch.
is pressed, the latch 7 rotates clockwise around the pivot 5 while resisting the compression coil spring 13, and the engagement with the receiving rod 6 of the receiving body 2 is released, and the door 3 is opened from the inside. be done.

〔Example〕

In the illustrated embodiment, in order to prevent the operating handle 9 from fully protruding in the direction of the door 3 due to the force of the compression coil spring 13, a mounting member 14 is provided at the right end of the operating handle, and a key is provided at the left end of the operating handle. Shape attachment members 20 are attached from the back side of the main body case 4 so as to abut on the operation handles 9, respectively.

In addition, a compression coil spring 10 inserted between the inner member 9b of the operating handle and the inner wall surface of the main body case 4 prevents the outer member 9a and the inner member 9b from coming apart, and the spring receiving part 12 and the inner end of the latch The function of the compression coil spring 13 inserted between the part 7a and the part 7a is assisted.

By covering the push rod 17 with the guide tube 16, deformation of the push rod 17 due to applied force is prevented, and the guide tube 16 also serves as a member for attaching the handle device to the door 3. The rotor of the lock 11 is provided with protrusions 19, and when the lock 11 is locked, the rotor rotates, and the protrusions 19 are accordingly rotated.
The right end 9 of the outer member of the operating handle 9 also rotates.
d comes into contact with the protrusion 19 and controls the movement of only the outer member 9a of the operating handle 9, making it impossible to open the door 3 from outside, that is, to push the operating handle 9 into the main body case 4.

[Effect of idea]

As described above, in the door handle device of the present invention, the operating handle has a double structure of an outer member and an inner member, and the pivot of the operating handle is largely deviated toward the latch side, so that the push rod of the internal opening mechanism is By bringing the tip into contact with the rightmost end of the operating handle, the door can be opened with relatively little operating force.
