Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims priority from Korean Patent Application No. 10-2013-0165682, filed on Dec. 27, 2013, the disclosure of which is incorporated herein in its entirety by reference.

TECHNICAL FIELD

The present disclosure relates to a refrigerator having a tiltable bin, shelf and/or pocket structure.

BACKGROUND

In general, a refrigerator is used to freeze or refrigerate food or the like and has a case divided into a freezer and a cold storage space therein. In this case, the freezer and the cold storage space have a plurality of shelves (not illustrated) for storing food. A shelf or pocket for containing a beverage bottle is inside the door of the freezer and the cold storage space.
When a pocket or shelf is fixed to the inside of the door, it may be difficult for a user to get beverage bottles, or the like, into and out of the pocket or shelf A tiltable pocket structure that rotates the pocket forward slightly when the user uses the pocket may improve the storage function and convenience of the refrigerator. A diagram illustrating the tiltable pocket structure is illustrated in FIG. 1.
FIG. 1A is a cross-sectional view illustrating a related art pocket structure in which the pocket/shelf is not tilted.
The tiltable pocket 11 is connected to a hinge 12 of a tilt case 10, and the hinge 12 serves as a rotation shaft. A hanger 14 in the tilt case 10 enables a stopper 13 on the tiltable pocket 11 to contact the tilt case 10. Therefore, the tiltable pocket 11 may be configured to rotate only a certain distance.
FIG. 1B is a cross-sectional view illustrating the related art tiltable pocket, tilted forward.
However, when the tiltable pocket structure is equipped with the tilt case 10 and the hinge 12, manufacturing costs increase and the refrigerator is more difficult to assemble. Also, such a hinge may have a relatively high rate of failure.

SUMMARY

The present disclosure has been made in an effort to provide a tiltable pocket, shelf or bin structure capable of tilting or rotating without a hinge or a tilt case.
The present disclosure has been made in an effort to control a rotational angle of the tiltable pocket, shelf or bin using a tilt stopper.
Embodiments of the present disclosure provide a refrigerator including: a door, a tiltable pocket, shelf or bin including a connecting shaft and a suspension projection, where the connecting shaft couples the tiltable pocket, shelf or bin to a door, and the suspension projection fixes a rotational angle of the tiltable pocket, shelf or bin and a tilt stopper on a surface of the door and coupled to the connecting shaft that prevents the tiltable pocket, shelf or bin from rotating beyond a predetermined angle.
The tilt stopper may include a suspension member and one or more hangers inside the suspension member to support the suspension member. The suspension member may have a rounded or arc-like shape.
Other embodiments of the present disclosure provide a refrigerator including: a door, a tiltable pocket, shelf or bin including a connecting shaft and a suspension projection, where the connecting shaft couples the tiltable pocket, shelf or bin to the door so the tiltable pocket, shelf or bin may rotate, a tilt stopper that prevents the tiltable pocket, shelf or bin from rotating beyond a first predetermined angle, and a sub-stopper configured to stop the rotation of the tiltable pocket, shelf or bin at a second predetermined angle.

FIG. 2 is an exploded perspective view of an exemplary refrigerator having a tiltable pocket, shelf or bin and a door, according to embodiments of the present disclosure.
As illustrated in FIG. 2, the refrigerator includes a tiltable pocket, shelf or bin 21, a tilt stopper 24, and a door bead 20, according to some embodiments of the present disclosure.
The tiltable pocket, shelf or bin 21 includes a connecting shaft 25 fixed to one side or each of two opposite sides of a case inside a refrigerator door.
The tiltable pocket, shelf or bin 21 includes a suspension projection 26 configured to set or adjust a rotational angle of the tilt pocket, shelf or bin 21. The left and right sides of the tiltable pocket, shelf or bin 21 have a connecting shaft 25 and a suspension projection 26 thereon.
The tilt stopper 24 prevents the tiltable pocket, shelf or bin 21 from rotating beyond a predetermined angle.
As illustrated in FIG. 3, the tilt stopper 24 includes a hinge groove 242 to be joined to the connecting shaft 25 of the tiltable pocket, shelf or bin 21 around which the tiltable pocket, shelf or bin 21 rotates.
The tilt stopper 24 includes a stopper fixing unit 241 connecting the tilt stopper 24 to the inside of a door.
The stopper fixing unit 241 includes a projection which protrudes outward (e.g., toward the refrigerator door) as illustrated in FIG. 3, and an insert 23, as illustrated in FIG. 2, at a position corresponding to the projection inside the refrigerator door that receives the projection of fixing unit 241 and joins the stopper fixing unit 241 to a surface of the door insert.
In another embodiment, the stopper fixing unit 241 has one or more holes or openings, and when the stopper fixing unit 241 is joined to the inside of the refrigerator door, a protrusion on the door contacts the hole or opening of the stopper fixing unit 241 and connects the stopper fixing unit 241 to a surface of the door.
As illustrated in FIG. 3, the tilt stopper 24 includes a suspension member 243 and a body, and the suspension member 243 may be hook-shaped and stops the tiltable pocket, shelf or bin from rotating when the suspension member 243 contacts suspension projection 26 of the tiltable pocket, shelf or bin 21. The body portion includes the hinge hole or opening 242 and the stopper fixing unit 241.
The hinge hole or opening 242 may be on an inner surface corresponding to the connecting shaft of the tiltable pocket, shelf or bin 21, and the hinge hole or opening 242 and the connecting shaft 25 may have complementary shapes (e.g., a cylindrical shape and a round shape). When the connecting shaft 25 of the tiltable pocket, shelf or bin 21 is inserted into the hinge hole or opening 242, the hinge hole or opening 242 enables the tiltable pocket, shelf or bin 21 to rotate around the connecting shaft 25.
One or more suspension bumps on which the suspension projection 26 catches are formed on the suspension member 243. The suspension member 243 may also include one or more concave troughs or depressions 245.
According to some embodiments, suspension member 243 has a plurality of concave troughs or depressions 245, and the suspension projection 26 has a round or cylindrical shape. As a result, when the suspension projection 26 crosses over a suspension bump 244, it catches on and/or in an adjacent concave trough/depression 245. The suspension projection 26 is positioned to cross over the suspension bump(s) 244 smoothly. The height of the suspension bump 244 is selected to enable smooth movement and secure catching of the suspension projection 26.
When the suspension member 243 has a plurality of concave troughs or depressions 245, the suspension projection 26 may be suspended on the suspension bumps 244 and rest in the concave troughs or depressions 245 of the suspension member 243 to control the rotational angle of the tiltable shelf, bin or pocket 21.
As illustrated in FIGS. A to 4C, when the tilt stopper 24 has three concave troughs or depressions 245, the rotational angle may be controlled in three stages (e.g., each stage changes the rotational angle by about 13°). Of course, there may be different numbers of bumps 244 and troughs 245 (e.g., 2-6), and the bumps and troughs may be configured so that different angles of tilt (e.g., 10-22.5°) are possible.
FIG. 4A is a diagram illustrating an initial state of an exemplary tiltable pocket, shelf or bin, where the tiltable pocket, shelf or bin is not rotated. When the tiltable pocket, shelf or bin is pulled forward (e.g., away from the door), the tiltable pocket, shelf or bin 21 rotates, and as a result, the tiltable pocket, shelf or bin 21 inclines or declines (e.g., tilts) forward at an angle. FIGS. 4B and 4C illustrate such states of rotation.
FIG. 4B illustrates an exemplary tiltable pocket, shelf or bin where suspension projection 26 is suspended on a first trough or depression of the hanger or bump 244 inside the door. In this case, the rotational angle is about 13°, although other angles are possible. In FIG. 4C, the suspension projection 26 is suspended on a third trough or depression of the hanger and rests upon the relatively thick neck of the tilt stopper 24. In this case, the rotational angle is about 39°.
Meanwhile, a sub-stopper 210 may on a lower surface of the door, as illustrated in FIG. 5. The sub-stopper 210 is inclined at an angle to prevent a lower end of the tiltable pocket, shelf or bin 21 from rotating beyond a predetermined angle.
The predetermined angle may be equal to or slightly less than the maximum angle of the rotation permitted by the tilt stopper 24. In the example of FIGS. 4C and 5, the predetermined angle may be 36°-39°. When the tiltable pocket, shelf or bin 21 rotates to a predetermined angle, the tiltable pocket, shelf or bin 21 contacts the sub-stopper and is prevented from rotating any further.
FIG. 6 is a perspective view illustrating an exemplary refrigerator having one or more tiltable pocket, shelf or bins on an inner surface of a door, according to some embodiments of the present disclosure.
As illustrated in FIG. 6, a plurality of tiltable pocket, shelf or bins may be on a surface of a refrigerator door.
All of the aforementioned components are not particularly required and some thereof may be omitted.
From the foregoing, it will be appreciated that various exemplary embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. The exemplary embodiments disclosed in the specification of the present disclosure will not limit the present disclosure. The scope of the present disclosure will be interpreted by the claims below, and it will be construed that all techniques within the scope equivalent thereto belong to the scope of the present disclosure.
