[ detailed description of the invention ]

As shown in fig. 1, the refrigerator 100 includes an insulated cabinet 101. The cabinet 101 has a storage chamber 102, and the storage chamber 102 has a front opening 104. The storage compartment 102 may be closed by one or a pair of doors (not shown).

The storage compartment 102 has a pair of rails 1 therein. In this embodiment, the rails 1 are fixed to the respective side compartment walls 103 of the storage compartment 102 by fixing means (not shown). In alternative embodiments, it is also possible that the rail 1 is at least partially formed integrally by the side compartment walls 103 of the storage compartment 101.

The refrigerator 100 includes a storage part 2, and both sides of the storage part 2 may be moved in front and rear directions by sliding along the respective rails 1. The storage component 2 may be moved forward toward the front opening 104 of the storage compartment 102 to be at least partially pulled out of the storage compartment 102.

The storage component 2 is movable between a first extreme position, in which the distance between the storage component 2 and a rear chamber wall 105 of the storage compartment 102 facing the front opening 104 is minimal, and a second extreme position, in which the distance between the storage component 2 and the rear chamber wall 105 is maximal. In fig. 1, 3 and 4, the storage part 2 is in a first extreme position relative to the rail 1, and in fig. 6, the storage part 2 is in a second extreme position relative to the rail 1.

In some embodiments, the storage component 2 moves back and forth independently of the door to close the storage compartment 102. It will be readily appreciated that in alternative embodiments, the storage component 2 may also move with the movement of the door.

The storage component 2 may comprise a container, such as an upwardly open drawer or tray. In other embodiments, the storage component 2 may also comprise a shelf of substantially plate shape.

As shown in fig. 2 to 5, a first roller 3 and a second roller 4 are provided between the storage part 2 and the rail 1. The storage component 2 is supported on the rail 1 via a first roller 3 and a second roller 4. The first roller 3 and the second roller 4 each comprise a wheel body which rolls around a horizontally extending shaft. When the storage part 2 slides relative to the rail 1, the first roller 3 and the second roller 4 roll by bearing the weight of the storage part 2. The first roller 3 and the second roller 4 are at least partially located between the storage part 2 and the rail 1 in the vertical direction.

As shown in fig. 3 and 4, when the storage part 2 is in a state of being completely retracted to the storage chamber 102, for example, in a first limit position, the first roller 3 and the second roller 4 are disposed at an interval in the front-rear direction, and the second roller 4 is positioned in front of the first roller 3. For example, the second roller 4 may be adjacent to a front opening of the storage chamber 102. The first roller 3 may be located at the rear of the storage chamber 102.

In an embodiment, at least one of the first roller 3 and the second roller 4 is fixed to the rail 1 to support the storage part 2. When the storage part 2 moves, the roller fixed on the track 1 is abutted against the storage part 2 and rolls. As shown in fig. 2 and 4, in the embodiment, the second roller 4 is fixed to the front of the rail 1 closer to the front opening of the storage chamber 102. When the storage part 2 moves, the second roller 4 slides along the corresponding portion of the storage part 2 and supports the storage part 2.

The first roller 3 may be fixed to the storage part 2, and the storage part 2 is supported on the rail 1 via the first roller 3. When the storage part 2 moves, the first roller 3 slides along the rail 1. The storage part 2 is supported by the first roller 3 and the second roller 4 and can smoothly move along the rail 1.

As shown in fig. 4, the first roller 3 may be fixed to the rear of the storage part 2. In an embodiment, the first roller 3 is spaced apart from the rear wall 21 of the storage part 2.

The refrigerator 100 includes a lateral roller 5 between the storage part 2 and the rail 1 in a lateral direction of the storage chamber 102 to restrict the storage part 2 from moving in a left and right direction during a front and rear movement, thereby reducing a shaking degree of the storage part 2. The transverse roller 5 may have a wheel body which rotates about an axis extending in the vertical direction.

As shown in fig. 3 and 4, the transverse roller 5 is mounted to the rail 1 and contacts the sidewall 22 of the storage part 2. When the storage part 2 moves in the front-rear direction, the side wall 22 of the storage part 2 slides along the lateral roller 5. Thereby, the degree of shaking of the storage part 2 in the lateral direction of the storage chamber 102 can be reduced.

In an alternative implementation, the transverse roller 5 may also be mounted to the storage component 2 and adapted to contact the rail 1 or the side compartment wall 103 to reduce the degree of shaking of the storage component 2 in the left-right direction.

The transverse roller 5 may be sheathed with an elastic body 51. The elastic body 51 contacts the side wall 22 of the storage member 2. This is not only advantageous for reducing noise when the storage part 2 is moved, but also advantageous for further reducing the degree of shaking of the storage part 2.

As shown in fig. 3, when the storage part 2 is in the closed position of being completely returned to the storage chamber 102, the transverse roller 5 fixed to the rail 1 is closer to the second roller 4 between the first roller 3 and the second roller 4. This advantageously increases the length of travel of the contact between the transverse roller 5 and the storage part 2. It will be appreciated that in alternative embodiments where the transverse roller 5 is fixed to the storage component 2, the transverse roller 5 may be closer to the first roller 3.

As shown in fig. 3, when the storage part 2 is in the first limit position, the lateral roller 5 may be located between the first roller 3 and the second roller 4 in the front-rear direction. The transverse roller 5 can also be in contact with the storage part 2, with the second roller 4 remaining in contact with the storage part 2.

As shown in fig. 6, when the storage part 2 is in the second limit position, the lateral roller 5 is located between the first roller 3 and the second roller 4 in the front-rear direction.

The transverse roller 5 may be located above the second roller 4 in the vertical direction to avoid the transverse roller 5 reducing the pull-out distance of the storage part 2.

The rail 1 may comprise a protrusion 7 at the front of the rail 1, the protrusion 7 being located behind the second roller 4. The first roller 3 fixed to the rear of the storage part 2 is in contact with the protrusion 7 when sliding to the front of the rail 1, so that it is possible to remind the user that the storage part 2 reaches the maximum design pulled-out state without continuously pulling the storage part 2 outward.

The storage component 2 may include an anti-tipping portion 6 located at least partially within the gap between the track 1 and the storage component 2. The anti-inversion portion 6 may protrude from the side wall 22 of the storage component 2. After the locker 2 moves forward by a predetermined stroke, the turnover preventing part 6 contacts the lateral roller 5, which may prevent the front end of the locker 2, which contains a heavy object with its center of gravity located outside the storage chamber 102, from being excessively turned downward and falling off the refrigerator 100.

The lateral roller 5 may be located between the protrusion 7 and the second roller 4 in the front-rear direction. Thus, even if the storage component 2 continues to move forward against the obstruction of the protrusion 7, for example, after the storage component 2 completely passes over the protrusion 7 or partially passes over the protrusion, the anti-turnover part 6 contacts with the lateral roller 5 to prevent the storage component 2 from being turned over excessively and falling off.

The transverse roller 5 can be located above the projection 7 in the vertical direction, which is more favorable for preventing the storage part 2 from being turned down excessively. Projections of the anti-reverse portion 6 and the protruding portion 7 in the front-rear direction may not overlap, so that the anti-reverse portion 6 may not contact the protruding portion 7. When the storing part 2 overcomes the obstruction of the projection part 7 and continues to move forwards, the anti-turnover part 6 contacts with the transverse roller 5 to prevent the storing part 2 from being turned downwards excessively and falling off.

The track 1 may include a bottom rail 11 and a side rail 12 connected to the bottom rail 11 and extending upward. The second roller 4 is fixed to the bottom rail 11. The first roller 3 slides along the bottom rail 11. The transverse roller 5 may be fixed to the side rail 12. The anti-turnover portion 7 may be located between the side rail 12 and the side wall 22 of the storage component 2.

The anti-reverse portion 6 may be disposed adjacent to the first roller 3. As shown in fig. 3, 4, and 6, the turnover preventing portion 6 may include a fourth roller 8 at least partially located between the side rail 12 and the side wall 22 in the left-right direction. The projection of the fourth roller 8 and the transverse roller 5 in the front-rear direction at least partially overlap, so that the fourth roller 8 and the transverse roller 5 abut against each other to prevent the storage part 2 from being turned over downward after the storage part 2 moves forward by a predetermined stroke.

The fourth roller 8 may be disposed in suspension so as to pass over the protrusion 7. The fourth roller 8 may be coupled to the first roller 3. In an embodiment, the fourth roller 8 and the first roller 3 may have the same central axis. The diameter of the fourth roller 8 is smaller than that of the first roller 3 so as to be suspended when the storage part 2 moves. The outside of the fourth roller 8 can be sleeved with an elastic sleeve.

In an alternative embodiment, the rollover protection can also be arranged non-rotatably on the side wall 22 of the storage part 2. For example, the anti-reverse part 6 may be integrally formed with the side wall 22 or may be assembled to the storage part 2 (for example, provided to the second roller 4).

Fig. 7 shows a schematic cross-sectional view of a storage unit according to another embodiment of the present invention. The difference from the previous embodiment is that in this embodiment, in addition to supporting the storage part 2, the first roller 43 extends between the rail 1 and the storage part 2, and the projection of the first roller 43 and the lateral roller 5 in the front-rear direction at least partially overlap, so that the first roller 43 and the lateral roller 5 abut against each other to prevent the storage part 2 from being turned downward when the storage part 2 is pulled out by a predetermined stroke. The turning-over prevention part 6 is formed by the first roller 43. The arrangement of the other components may be the same as in the previously described embodiments.
