Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storehouse equipped with a refrigeration cycle of a freezer or refrigerator, in which a double door is supported in the front opening of a storehouse body without a partition wall in the center so as to be freely openable and closable.

As shown in Figure 1, there is a refrigerator that has a storage compartment 1 without a partition wall in the center of the front entrance and has doors 2 and 3 that open on both the left and right sides. Since the freely pivotable hinge mechanism was fixed at one point, it had various drawbacks.

That is, the narrower the end surfaces 2a, 3a of the doors 2, 3, the closer the pivot parts of the doors 2, 3 must be to the point B (shown in the second diagram) of the refrigerator body 4, and as a practical matter, end face 2
It is not possible to completely eliminate the spacing between a and 3a. This is because the doors 2 and 3 are thick, and the end surface 2a
, 3a, the inner weave parts 2b, 3b and the outer ends 2c, 3c have different distances from the pivot part of the hinge mechanism. Therefore, if the pivot part of the hinge mechanism is located even slightly forward of the above point B, this point will be used as the fulcrum. As the doors 2 and 3 rotate, the inner ends 2b and 3b of the doors 2 and 3 interfere with each other, making it impossible to open and close the doors 2 and 3. Also, suppose doors 2 and 3 are opened at point B above.
Even if it were possible to pivot the doors 2 and 3 (although it would be extremely difficult in practice...), when the doors 2 and 3 are opened, the thickness of the doors 2 and 3 should be 10 and the backing 5, This protrudes outward from the side wall of the refrigerator main body 4 by a dimension a corresponding to the thickness of 6, which has the drawback of increasing the installation space of the refrigerator and damaging the doors 2 and 3 by hitting other adjacent appliances. For the above reasons, in the conventional case, it is structurally unavoidable to form a gap between the end faces 2a and 3a of the doors 2 and 3, and in order to seal this gap, the packings 5 and 6 may contain magnets. Various measures were required, such as providing maneuverable fins 5a and 6a and overlapping the visible fins 5a and 6a to isolate the storage 1 from the outside air.

The present invention has been devised in view of the above-mentioned matters, and will be explained in detail below with reference to an embodiment shown in the drawings.

Reference numeral 11 denotes a refrigerator body (
The left and right heat-insulating doors 12 and 13 are pivotally supported at the front closing part of the storage body by means of upper and lower hinge mechanisms so as to be openable and closable.

Reference numerals 14 and 15 denote gaskets disposed along the free end portions of the doors 12 and 13 and the inner green portions.

When the doors 12, 13 are closed, the gaskets 14, 15 are in close contact with the gaskets on the front closing twill portion of the refrigerator body 11 and the opposite free end surface of the door to prevent leakage of cold air within the storage chamber. in this case,
If the hinge mechanisms of the doors 12 and 13 are fixed as in the past, interference will occur on the door end surfaces when the doors are opened and closed.
In the present invention, this is absorbed by displacing the pivot portion of the hinge mechanism. The specific configuration of the hinge mechanism will be described below. Note that the upper, lower, left, and right hinge mechanisms all have the same structure. Reference numeral 16 denotes a hinge body fixed to the refrigerator body 11 side with screws, etc., and a pivot 19 is formed protruding from the upper surface of the distal side of the receiving piece 17 for pivotally supporting one end of the slider 18 in a freely rotatable manner. . Slider 18 above
has a rotating shaft 20 erected at its tip, which rotatably supports one end of the door 12 or 13, and a spring 21 is always attached.
The doors 12 and 13 are energized in the closing direction. 22,
Reference numeral 23 denotes a locking device attached to the top and bottom of the free end side of the doors 12, 13, and the front end thereof has a slanted portion 22a, 22.
A substantially doglegged cam-shaped protrusion 22 having portions b, 23a, and 23b.
c, 23c are formed, and the cam-shaped protrusions 22c, 23
c can be freely engaged with and disengaged from engagement parts 24 and 25, which are rotating rollers attached above and below the approximate center of the front opening □ of the refrigerator main body 11.

That is, when the doors 12, 13 are closed, the inclined portions 22a, 23a of the cam-shaped protrusions 22c, 23c first contact the engaging portions 24, 25, and then the doors 12, 13 are closed. When pressed in the closing direction, the rotating rollers 24 and 25 work on the oblique portions 22a and 23a of the cam-like protrusions 22c and 23c, and the slider 18 moves the pivot 19 against the urging force of the spring 21. Turn the sardine into the center and rotate above. -ra-
When 24 and 25 reach the tops of the cam-like protrusions 22c and 23c, the amount of displacement of the rotating shaft 20 of the slider 18 reaches its maximum, and in this state, the free ends of the doors 12 and 13 are prevented from interfering with each other. There is. So, door 12? When the closing operation of 13 continues, the rotating rollers 24 and 25 move on the oblique portions 22b and 23b of the cam-shaped protrusions 22c and 23c,
The engagement state between the rotating rollers 24, 25 and the cam'-shaped protrusions 22c, 23c is maintained with the packings 14, 15 provided inside the doors 12, 13 in close contact with the front opening edge of the refrigerator main body 11. Ru. At this time, the doors 12 and 13 are always subjected to the force of the spring 21 via the slider 18,
The packings 14 and 15 provided on the free end faces of the doors I2 and 13 are also pressed into close contact with each other to prevent cold air from leaking inside the storage.
In addition, when opening the doors 12 and 13, the operation is performed in the opposite manner to the above operation, and when the rotating rollers 24 and 25 and the locking smells 22 and 23 are disengaged and disengaged, the slider 18 is returned to its original position by the biasing force of the spring 21. After returning, the doors 12 and 13 are rotated about the rotation axis 20. Therefore, when the doors 12 and 13 are opened 90 degrees, the doors 12 and 1
3 does not protrude outward. FIGS. 13 to 16 show other embodiments of the present invention, in which rotary rollers 28 and 29 are attached to the tips of locking shells 26 and 27 attached to the free ends of doors 12 and 13, and The engaging portion 30 attached to the refrigerator main body 11 side is formed in a hexagonal shape.

By configuring the locking tools 26, 27 and the engaging portion 30 in this manner, the same effects as in the above embodiment can be obtained.

That is, during the opening/closing operation of the doors 12, 13, the rotating rollers 28, 29 of the locking tools 26, 27 on the door 12, 13 side slide on the ridgeline portions 30a, 30b of the hexagonal engagement portion 30, and the doors 12, 1
The rotating shaft 20 of No. 3 is displaced. This displacement of the rotating shaft 20 prevents the doors 12 and 13 from interfering with each other on the free end side. As described above, in the case where the double-door door is pivotally supported in the front opening of the storage main body without a partition wall in the center so that it can be opened and closed freely, the pivot part of the door is displaced and constantly pressed in the opening direction of the door. The supporting hinge mechanism pivots the door, and
The locking device attached to the free end side of the door and the engaging part attached to the storage main body side keep the door closed. Not only does this eliminate interference, but it also eliminates the need to form a gap at the free end of the door, so there is no need for a special packing structure, making it extremely simple and inexpensive to manufacture. It is something that can be played.
