Disclosure of Invention

[ technical problem to be solved by the invention ]

In such a refrigerator, when a user erroneously performs a locking operation in a state where the lid is opened, the locking device collides with the box main body when the lid is closed, and the locking device may be broken due to, for example, breakage of the claw portion for engagement.

Accordingly, an object of the present invention is to provide a refrigerator in which a locking device is not easily broken down.

[ technical means for solving problems ]

The invention provides a refrigerator comprising a main body part and a cover part, wherein the main body part is provided with an opening part and can accommodate objects inside; the lid section moves relative to the body section to open and close the opening section, one of the body section or the lid section has an engaged section, the other of the body section or the lid section has an engaging section that is movable relative to the engaged section and that holds the lid section in a closed state by engaging with the engaged section, the engaging section has a movement restricting section that faces one side of a movement range relative to the engaged section and that restricts movement of the lid section relative to the body section by engaging with the engaged section, the engaging section moves to a locked state, a free state, and a retracted state, wherein the locked state is a state in which the movement restricting section engages with the engaged section; the free state is a state in which the engagement is released, the engagement portion is separated from the engaged portion so that the movement restricting portion and the engaged portion face each other, and the retracted state is a state in which the engagement portion is separated from the engaged portion by the movement restricting portion facing away from the engaged portion.

According to this configuration, when the user erroneously moves the engaging portion before closing the lid portion, the engaging portion is in the retracted state, and the movement restricting portion is not engaged with the engaged portion. Therefore, even if the lid is closed, the engaging portion does not become the locked state. Further, since the engaging portion is in the retracted state and the movement restricting portion is separated from the engaged portion, the movement restricting portion does not collide with the engaged portion and is not damaged.

And, may be: the locking device comprises a main operation part and a secondary operation part, wherein the main operation part operates the clamping part to enable the clamping part to move between a locking state and a free state, wherein the locking state enables the clamping part to be clamped with the clamped part; the free state is a state in which the engagement is released; the sub operation unit restricts an operation of the main operation unit from changing from a state corresponding to the free state to a state corresponding to the locked state.

According to this configuration, the sub operation unit restricts the operation of the main operation unit from changing from the state corresponding to the free state to the state corresponding to the locked state. Therefore, the engagement portion can be prevented from being in the locked state when the user does not intend.

And, may be: the main operation portion is provided on the lid portion so as to move in a vertical direction with respect to the lid portion, the sub operation portion is provided above the main operation portion so as to move in a vertical direction with respect to the main operation portion, and when the lid portion is in an open state and the lid portion is closed in a state where the sub operation portion is moved from above to below, the engagement portion is brought into the retracted state, and a state where the lid portion is allowed to move with respect to the main body portion is maintained.

According to this configuration, even when the lid portion is closed in a state where the sub-operation portion is moved from the upper side to the lower side, the engagement portion does not hold the lid portion in the closed state. Therefore, even when the user erroneously operates the lock device, the lock device can be prevented from being brought into the locked state.

And, may be: the main operation portion is provided in the lid portion so as to move in a horizontal direction with respect to the lid portion, and when the lid portion is in an open state and the lid portion is closed in a state in which the sub operation portion has been moved, the engagement portion is brought into the retracted state, and a state in which the lid portion is allowed to move with respect to the main body portion is maintained.

According to this configuration, even when the lid section is closed in a state in which the sub-operation section is moved, the engagement section does not hold the lid section in the closed state. Therefore, even when the user erroneously operates the lock device, the lock device can be prevented from being brought into the locked state.

And, may be: the engaged portion is fixedly provided to the body portion, the engaging portion is rotatable with respect to the body portion of the lid portion, and a rotation range of the engaging portion is set to extend from a front side to a depth side beyond the engaged portion with reference to the engaged portion.

According to this configuration, the locked state, the free state, and the retracted state can be set by setting the rotation range of the engaging portion with respect to the engaged portion that is fixedly provided. Therefore, a locked state that prevents a user from unwanted can be achieved with a simple structure.

[ Effect of the invention ]

According to the present invention, the movement restricting portion does not collide with the engaged portion and is not damaged. Therefore, the locking device is less prone to malfunction.

Detailed Description

Next, the present invention will be described by referring to an embodiment. Fig. 1 shows the shape of the refrigerator 1 according to the present embodiment. However, in fig. 1, the appearance of the main body portion is shown only by a two-dot chain line.

As in the case of the refrigerator of the related art, the refrigerator 1 of the present embodiment includes a main body 2 and a lid 3, wherein the main body 2 has an opening 21 that opens upward and is capable of accommodating the stored items therein; the lid 3 moves relative to the body 2 to open and close the opening 21. As shown in fig. 4(a) to (c), a lock device L for holding the lid 3 in the closed state is provided over the body 2 and the lid 3. The refrigerator 1 is rectangular in plan view. The lid 3 of the present embodiment is formed so as to be opened in two directions, and in the present embodiment, the movement of the lid 3 with respect to the body 2 can be, for example, a movement of moving the lid 3 upward of the opening 21 in a substantially parallel state so that the entire lid 3 is separated from the body 2. The movement may be a movement in which one of two parallel long sides in the shape in plan view functions as a hinge, and the lid 3 is lifted up and rotated on the other long side. By this movement, the lid 3 can be brought into the closed state and the open state.

As shown in the vertical sectional shapes of fig. 4(a) and (b), the body 2 has a fixed shaft 22 as an engaged portion. The fixed shaft 22 is fixedly provided to the main body 2. In the present embodiment, although not shown, the fixed shafts 22 are provided along the two long sides of the opening 21 of the body 2. Two fixing shafts 22 are provided on each long side at positions symmetrical with respect to the center in the longitudinal direction.

The cover portion 3 has a main lever (main operation portion) 31 and a sub lever (sub operation portion) 32 as a lever unit LU operated by the user. As shown in fig. 1, the main lever 31 and the sub lever 32 are provided at the same position, which is the center in the longitudinal direction of both end portions having the long side of the cover portion 3.

As shown in the vertical sectional shapes of fig. 4(a) to (c), the cover portion 3 has a lock member 33 as an engaging portion, and the lock member 33 is movable relative to the fixed shaft 22 of the body portion 2 and is engaged with the fixed shaft 22. The locking member 33 holds the lid portion 3 in the closed state by cooperating with the fixed shaft 22. That is, the locking device L includes the fixed shaft 22 provided to the body 2 and the locking member 33 provided to the lid 3. The lock member 33 rotates with respect to the main body 3A of the cover 3. The rotation range of the locking member 33 is set to extend from the front side to the depth side beyond the fixed shaft 22 with reference to the fixed shaft 22 of the main body 2. As shown in the drawing, the lock member 33 extends downward with the lid 3 horizontal with reference to the rotation axis 331 which is the rotation center of the lock member 33.

The lock member 33 has a claw portion 332 as a movement restricting portion. The claw portion 332 faces one side of the rotation range with respect to the fixed shaft 22. The claw portion 332 is shaped to face the left side in the drawing as shown in fig. 4(a) to (c), for example, and is engaged with the fixed shaft 22 to restrict the upward movement of the lid 3. That is, when the claw portions 332 engage with the fixed shaft 22, even if the user tries to lift the lid portion 3, the engagement cannot be released by only the lifting manpower, and therefore the lid portion 3 cannot be lifted.

The lock member 33 rotates between a locked state shown in fig. 4 (b) and a free state shown in fig. 4(a), the locked state being engaged with the fixed shaft 22; the free state is a state in which the engagement is released. The free state is a state in which the lock member 33 is located on the front side with respect to the fixed shaft 22 in the rotation range. That is, the claw portion 332 of the lock member 33 is in a state of being separated from the fixed shaft 22 so as to face the fixed shaft 22. In the state shown in fig. 4(a), the fixed shaft 22 is located on the left side, and the claw portion 332 is located on the right side. Therefore, the engagement of the lock member 33 with the fixed shaft 22 is released. The locked state is a state in which the lock member 33 is positioned on the front side (left side in the figure) with respect to the fixed shaft 22 in the above-described rotation range and engaged with the fixed shaft 22. The lock member 33 is in the retracted state shown in fig. 4 (c) in addition to the locked state and the free state. The retracted state is a state in which the lock member 33 passes over the fixed shaft 22 (not shown in fig. 4 c) in the above-described rotation range and is located on the deep side (left side in the drawing) with respect to the fixed shaft 22. That is, the claw portion 332 of the lock member 33 is away from the fixed shaft 22 and away from the fixed shaft 22. In the state shown in fig. 4 c, in the state where the cover 3 is closed, the position where the fixed shaft 22 exists (the open state of the cover 3 is shown, and therefore the fixed shaft 22 itself is not shown) is located on the right side, and the claw portion 332 is located on the left side. In the present embodiment, the locked state, the free state, and the retracted state can be set by setting the rotation range of the lock member 33 with respect to the fixed shaft 22 that is fixedly provided. Therefore, a locked state that prevents a user from unwanted can be achieved with a simple structure.

As shown in fig. 1 to 3 and 5 to 7, the main lever 31 is provided on the lid 3 so as to move in the vertical direction with respect to the lid 3. More specifically, the main lever operation unit 311, which is a portion of the main lever 31 operated by the user, moves in the vertical direction. When the main lever operation portion 311 is operated, the main lever 31 is rotated integrally with respect to the main body 3A of the cover 3 about the main lever rotation shaft 312. The main lever 31 and the lock member 33 are physically coupled by a rod-like body or the like, and are integrally moved (rotated) by the operation of the main lever 31. Therefore, when the main lever 31 is moved, the locking member 33 is interlocked. Further, the main lever 31 and the lock member 33 may be an integral member. The main lever 31 is operated by a user to move the lock member 33 between the locked state and the free state when the lid 3 is in the closed state. Further, when the lid portion 3 is in the open state, the lock member 33 is moved between the retracted state and the free state.

The sub-lever 32 is provided above the main lever 31 so as to move in the vertical direction with respect to the main lever 31. More specifically, the sub-lever operation portion 321, which is a portion of the sub-lever 32 operated by the user, moves in the vertical direction. The sub-lever 32 is integrally rotatable about the sub-lever rotation shaft 322 with respect to the main lever 31. The sub-lever 32 is biased upward by a spring (spring not shown) with respect to the main lever 31, and is positioned at the upper end of the rotation range in all cases except when pressed by the user. The sub lever operation portion 321 is provided to cover the upper side of the main lever operation portion 311. Therefore, the main lever operation portion 311 is directly operated by the user when moving upward, but is indirectly operated via the sub lever operation portion 321 when moving downward. The main lever 31 and the sub lever 32 (more specifically, the lever operating portions 311 and 321) move in the same direction. Since the moving direction is the same, the user can easily understand the operation method, and the operability is good. The sub lever 32 restricts the operation of the main lever 31 from the state corresponding to the free state to the state corresponding to the locked state. This restriction can prevent the lock member 33 from being in the locked state when the user does not want it. This restriction prevents the main lever 31 from moving downward. In order to restrict the movement of the main lever 31, a protrusion 323 protruding downward is integrally provided on the sub lever 32. In response to this, the main body 3A of the lid 3 is provided with a sub-lever contact portion 34.

As shown in fig. 5, in a state where an end portion (a left portion in the drawing) of the sub lever 32 in the direction along the short side of the cover 3 is located upward, the lower end surface of the protruding portion 323 abuts on the upper end surface of the sub lever abutting portion 34. Therefore, even if the user presses the main lever 31 downward, the main lever 31 does not move.

Next, as shown in fig. 6, in a state where the user presses the sub lever 32 downward to move a portion closer to the end (left portion in the drawing) in the direction along the short side of the lid portion 3 in the sub lever 32 downward, the lower end surface of the protruding portion 323 located on the opposite side of the sub lever rotation shaft 322 is separated from the upper end surface of the sub lever contact portion 34. Accordingly, when the user presses the main lever 31 downward, the main lever 31 rotates about the main lever rotation shaft 312 as shown in fig. 7, and a central portion (a right portion in the drawing) of the main lever 31 in a direction along the short side of the lid portion 3 moves downward.

The operation of the main lever 31 and the sub lever 32 shown in fig. 5 to 7 is the same regardless of whether the lid portion 3 is in the closed state or in the open state.

When the lid 3 is in the closed state, when the sub lever 32 is moved from the upper side to the lower side, the main lever 31 is also moved from the upper side to the lower side together with the sub lever, and the lever unit LU is changed from the state shown in fig. 1 to the state shown in fig. 2. Since the two

levers

31 and 32 are moved together from the upper side to the lower side, the user can operate the lock device L in one operation. Accordingly, the locking member 33 rotates to contact the fixed shaft 22, and the claw portion 332 engages with the fixed shaft 22. Therefore, as shown in fig. 4 (b), the lock member 33 is in the locked state. In this way, the user can be brought into the locked state only by pressing the sub-lever 32. Conversely, when the locked state is released and the lid 3 is opened, the user only has to pull up the main lever 31 (move it upward from below).

On the other hand, when the lid 3 is in the open state, the sub lever 32 is moved from above to below, and the main lever 31 is also moved from above to below together with the sub lever. So far the same as the off state. However, when the lid 3 is in the open state, the locking member 33 does not contact the fixed shaft 22, and therefore, further rotates beyond the position in the locked state. Therefore, as shown in fig. 4 (c), the lock member 33 is in the retracted state. The handle unit LU is in the state shown in fig. 3.

Fig. 8 shows a state of the cover 3 (schematically illustrated) and a state of the lock member 33 in combination in accordance with the operation performed by the user. Summarized in the preceding paragraph are the usual actions. Even if the lid portion 3 is closed, the locking member 33 is in a free state. When the sub-lever 32 is pressed (shown by a triangle), the lock member 33 is in a locked state.

On the other hand, the following paragraphs summarize unexpected behavior. When the user presses the sub lever 32 by mistake in a state where the cover 3 is opened, the lock member 33 is in a retracted state. At this time, even if the lid portion 3 is closed, the lock member 33 is in the retracted state. That is, the locking state is not established, and the locking member 33 is kept away from the fixed shaft 22. Therefore, when the cover 3 is closed, the lock member 33 does not collide with the fixed shaft 22 and is not broken. When the user grips the main lever 31 again and lifts the lid 3, the main lever 31 is pulled up in association with the lifting, and therefore, the lock member 33 returns to the free state. The subsequent operation is the same as the normal operation, and the lock member 33 is kept in a free state even when the lid portion 3 is closed. When the sub-lever 32 is pressed, the lock member 33 is in a locked state.

In the refrigerator 1 of the present embodiment configured as described above, the locking device L is operated only when the user operates the refrigerator. Therefore, for example, the lid portion 3 is not brought into the locked state by only moving the lid portion 3 downward to be aligned with the body portion 2, and therefore, even when the lid portion 3 must be frequently opened and closed, the cold air inside the body portion 2 is not easily let out to the outside by closing the lid portion 3 while keeping the lock member 33 in the free state, and even if the user does not reach the main lever 31 every time, the lid portion 3 can be opened only by putting fingers on an arbitrary portion such as an end portion of the lid portion 3 and lifting up the lid portion 3. Therefore, the use convenience is good.

While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

For example, the lid 3 of the above embodiment is "double-opened", but the lid 3 may be formed with a hinge that cannot be separated from the body 2 on one of two parallel long sides of the shape in plan view.

In the locking device L, the locking device L of the above embodiment includes the fixed shaft 22 provided on the body 2 and the locking member 33 provided on the lid 3, but conversely, the body 2 may include the locking member and the lid 3 may include the fixed shaft.

In the above embodiment, the engaging portion is used as the lock member 33, and the engaged portion is used as the fixed shaft 22. Further, a movement restricting portion that restricts upward movement of the lid portion 3 by engaging with the engaged portion (fixed shaft 22) is provided at the claw portion 332 of the lock member 33. However, the shape and the engagement form of these parts are not limited to the above embodiment, and may be implemented by various modifications.

The direction of movement of the main lever 31 and the direction of movement of the sub lever 32 are the same in the above embodiment, but may be opposite to each other and different from each other. In the case of such a configuration, for example, in the case of slamming the lid 3, even if the sub lever 32 moves due to the inertia of its own weight, the main lever 31 moves in a different direction, and therefore, it is advantageous in that the main lever 31 itself can be suppressed from moving due to the inertia of its own weight.

In the above embodiment, the sub lever 32 has the protrusion 323 integrally with the sub lever 32 in order to restrict the operation of the main lever 31 from the state corresponding to the free state to the state corresponding to the locked state. That is, the protrusion 323 is a part of the sub-handle 32. However, the mechanism for restricting the main lever 31 is not limited thereto. For example, the main lever 31 may be provided separately from the sub lever 32, and may be prevented from moving to a state corresponding to the locked state by moving the main lever 31 to protrude from the main body 3A of the lid 3 in accordance with the operation of the sub lever 32.
