When the case main body 57 is placed on such an elevating table 67, the second wall portion 57dR and the first wall portion 57dR of the case main body 57 are between the second wall portion 58dR and the first wall portion 58dL of the elevating table main body 58. The wall portion 57dL is inserted. The second wall portion 57dR, the first wall portion 57dL, and the rear side wall portion 57c of the case main body 57 face the peripheral wall portion 58A of the elevating platform main body 58.

The case body 57 is positioned on the bottom surface 58a between the second wall 58dR and the first wall 58dL of the lift body 58 in the lateral width direction with respect to the lift body 58. .. The pair of locking projections 57j in the case body 57 fits into the pair of concave grooves 58j on the elevating table body 58 side. The case main body 57 is positioned in the depth direction with respect to the elevating table main body 58 by fitting each locking projection 57j of the case main body 57 into each concave groove 58j on the elevating table main body 58 side.

When the case body 57 is attached to the elevating table body 58, it is in the −Y direction side of the flat plate portions 57eR and 57eL in the upper door accommodating case 56A and in the −Y direction of the flat plate portions 58eR and 58eL of the elevating table 67. The side is inserted between the side ribs 61C and 61D shown in FIG. Therefore, in the upper door accommodating case 56A, the + Y direction side of the flat plate portions 57eR and 57eL protrudes in the + Y direction from the side ribs 61C and 61D.

Here, the interval regulation stopper in the elevating table main body 58 will be described in detail.
As shown in FIGS. 4 and 5, the upper door accommodating case 56A of the present embodiment has a pair of spacing restricting stoppers 58Ac that regulate the distance from the middle door accommodating case 56B in the vertical direction. The elevating table main body 58 of the middle door accommodating case 56B, which has the same configuration as the upper door accommodating case 56A, also has an interval regulation stopper 58Ac.

As described above, the pair of spacing control stoppers 58Ac comprises a part of the pair of locking projections 58ER and EL provided on both sides of the elevating table main body 58 in the lateral width direction. The pair of spacing regulation stoppers 58Ac in the upper door accommodating case 56A protrudes toward the middle door accommodating case 56B located directly below, and can abut on the middle door accommodating case 56B from above.

Specifically, when the upper door accommodating case 56A is lowered, each spacing restriction stopper 58Ac of the upper door accommodating case 56A hits the upper end surfaces 58aL and 58aR of the locking projections 58ER and EL in the middle door accommodating case 56B, respectively. Contact. The upper end surfaces 58aL and 58aR of the locking projections 58ER and EL in the middle door accommodating case 56B are "stopper receiving surfaces" to which the interval restricting stopper 58Ac of the interval regulating stopper 58Ac in the upper door accommodating case 56A can abut. Hereinafter, the upper end surfaces 58aR and 58aL of the locking projections 58ER and EL may be referred to as stopper receiving surfaces 58aR and 58aL.

The pair of locking projections 58EL and 58ER are inserted into the stopper insertion grooves g1 and g2 (FIG. 3) formed on the inner side (-Y direction side) of each rail portion 64, respectively. As a result, when the upper door accommodating case 56A is viewed from the + Y direction, the pair of locking projections 58ER and EL are hidden in the stopper insertion grooves g1 and g2 and are difficult for the user to see.

Further, since the stopper insertion groove g1 is formed in the depth direction with a width slightly larger than the width in the depth direction of the locking projection EL, the locking projection EL is substantially in the depth direction with respect to the stopper insertion groove g1. It is inserted without a gap. As a result, the locking projection EL abuts on the inner wall of the stopper insertion groove g1 facing the Y direction, and the weight of the contained object accommodated in the case body 57 causes the refrigerating chamber 27 (+ Y direction) of the upper door accommodating case 56A. It is possible to restrict the side from tilting downward (-Z direction).

The vertical length of each spacing regulation stopper 58Ac in the locking projections 58ER and EL, that is, the protruding heights on the upper end surfaces 58aL, 58aR side and the lower end surface 58bL, 58bR side with respect to the peripheral wall portion 58A can be appropriately changed. It is possible. In the present embodiment, the lower end surfaces 58bR, 58bR side of the locking projections 58ER, EL are projected downward from the peripheral wall portion 58A of the elevating platform main body 58 more than the upper end surfaces 58aL, 58aR side, and the spacing control stopper is used. Although it is made to function as 58Ac, it may be configured to function as an interval regulation stopper 58Ac by projecting the upper end surfaces 58aL and 58aR side greatly from the peripheral wall portion 58A. Since it is only necessary to regulate the vertical spacing between the upper door accommodating case 56A and the middle door accommodating case 56B so that the fingers are not pinched, the spacing is restricted on the upper side, the lower side, or both of the elevating table main body 58. A stopper 58Ac may be provided.

The shapes of the locking projections 58ER and EL (interval regulation stopper 58Ac) are not limited to the above-mentioned shapes and can be changed as appropriate. The outer shape is not limited to the prismatic shape, but may be a cylindrical shape, and various other shapes can be adopted.

In the present embodiment, the elevating table 67 including the interval regulation stopper 58Ac is formed by injection molding. Therefore, it is not necessary to attach the interval regulation stopper 58Ac as a separate part to the elevating table main body 58, and the interval restricting stopper 58Ac can be integrally formed with the elevating table main body 58, so that the number of parts can be reduced and the man-hours can be reduced. Reduction is possible.

The operation member 59 includes an operation unit 59a, a pair of urging member holders 59b, a pair of guide ribs 59c, and a pair of pressing members 59d.
As shown in FIG. 9, the operation unit 59a has a frame shape extending in the lateral width direction, and is arranged so as to face the front end plate portion 58b of the elevating table main body 58. On the lower surface side of the operation unit 59a, a groove portion 59h into which a user's hand enters is opened from below.

The urging member holder 59b is a frame body that holds the urging member 77 that urges the operating member 59 in the −Y direction. The urging member holder 59b has a rectangular frame shape having a length in the moving direction (Y direction) of the operating portion 59a, and has a locking portion 59i for locking the end portion of the urging member 77 in the −Y direction. It has a guide shaft 59j (FIG. 10) extending from the locking portion 59i toward the operating portion 59a.

The urging member 77 held by the urging member holder 59b is, for example, a compression coil spring. The urging member 77 is extrapolated to the guide shaft 59j, one end of which is locked to the locking portion 59i, and the other end of which is locked to the locking portion 58p (FIG. 11) on the elevator body 58 side. As a result, as shown in FIG. 9, the urging member 77 is arranged between the operating member 59 and the elevating table main body 58, and urges the operating member 59 with respect to the elevating table main body 58 in the −Y direction.

Each of the pair of guide ribs 59c is a protrusion extending along the moving direction (Y direction) of the operating portion 59a. The guide ribs 59c are arranged at intervals in the lateral width direction (X direction), and are located outside the X-direction of each urging member holder 59b.
The pair of guide ribs 59k are protrusions that are parallel to the pair of guide ribs 59c and are arranged between them, and each of them extends along the moving direction (Y direction) of the operating portion 59a. The pair of guide ribs 59k are arranged at a distance narrower than the distance between the pair of guide ribs 59c, and are located inside each of the urging member holders 59b in the X direction.
These guide ribs 59c and 59k are inserted into a pair of guide grooves 58k formed on the back surface side of the elevating table main body 58 shown in FIG. 11, and can move in the depth direction along each guide groove 58k.

In the following, as shown in FIG. 9, the position when the operating member 59 moves most in the −Y direction due to the urging force of the pair of urging members 77 is referred to as a locking position. Although not shown, the position when the operation unit 59a moves most in the + Y direction by the user's operation is referred to as an unlocked position.

The movement distance in the depth direction from the locking position to the unlocking position (hereinafter, the moving distance) is based on the length of the guide rib 59k (hereinafter, the insertion length) inserted into each guide groove 58k at the locking position. Is also short. As a result, even if the operating member 59 moves to the unlocked position, the entire guide rib 59k is not pulled out from each guide groove 58k.

As shown in FIG. 10, in the guide rib 59c on the −X direction side, the pressing member 59d is provided on the most −X direction side. Further, in the guide rib 59c on the + X direction side, the pressing member 59d is provided on the most + X direction side. Each pressing member 59d is connected to a guide rib 59c.

The protrusion 59e is a chevron having a top portion 59f in the protrusion direction when viewed from the + Z direction. The top portion 59f may be a plane parallel to the flat plate portion 59g, or may be a curved surface having a convex arc shape when viewed from the + Z direction. In the example shown in FIG. 10, the outer shape of the protrusion 59e seen from the + Z direction is an isosceles triangle, and the top 59f is a curved surface having a convex arc shape.
The width of the protrusion 59e in the depth direction is about twice the moving distance of the operating member 59.
The protrusion 59e is located in the second guide portion 58t of the lift main body 58 shown in FIG.

In the operating member 59 of the present embodiment, the operating portion 59a, the urging member holder 59b, the guide rib 59c, and the pressing member 59d are integrally formed with each other. Therefore, since the meandering and rotation of the operating member 59 in the horizontal plane are suppressed, the operating member 59 can move linearly along the depth direction.

"Bottom cover"
As shown in FIGS. 9 and 10, the lower cover 60 has an operating member 59, each urging member 77, a vibration absorbing member 78, and each first locking portion 70 mounted on the elevating table main body 58.

The lower cover 60 has an asymmetrical shape in the lateral width direction.
The outer shape of the bottom surface portion 60a seen from the Y direction is substantially the same as the bottom surface portion 58a (FIG. 11) of the elevating table main body 58 except that the operation portion 59a has a through groove 60h at the end in the + Y direction. ..

As shown in FIG. 10, the lower cover 60 has a bottom surface portion 60a and a peripheral wall portion 60B extending in the + Z direction from the outer peripheral edge of the bottom surface portion 60a. The peripheral wall portion 60B has a rear side plate portion 60c located on the outer edge of the bottom surface portion 60a in the −Y direction and a second portion located on both sides of the rear side plate portion 60c in the width direction at a narrow portion of the bottom surface portion 60a on the −Y direction side. A pair of flat plate portions 60g facing outward in the X direction from each end of the plate portions 60bR and the first side plate portion 60bL, the second plate portions 60bR and 60bL on the + Y direction side, and the bottom surface portion 60a on the + Y direction side. The first plate portion 60eL and the second plate portion 60eR located in a wide portion, the corner portion 60s located on the + Y direction side of the first plate portion 60eL, and the notch located on the + Y direction side of the second plate portion 60eR. It has a plate portion 60x and. The cutout plate portion 60x is inclined in the −X direction from the second plate portion 60eR side toward the + Y direction side.

The bottom surface portion 60a is provided with a screw fixing boss 60d having a through hole through which a screw 76 for fixing to the elevating table main body 58 is inserted. As shown in FIG. 9, the back surface side of the screw fixing boss 60d is recessed in the + Z direction so that the screw head of the screw 76 does not protrude.
The bottom surface portion 60a forms the bottom surface of the elevating table 67 except for the through groove 60h.

The first plate portion 60eL, the second plate portion 60eR, and the notched plate portion 60x are provided along the peripheral edge of a wide portion of the bottom surface portion 60a on the + Y direction side. The second plate portions 60bR and 60bL are provided along the peripheral edge of the narrow portion of the bottom surface portion 60a on the −Y direction side.

When the lower cover 60 is attached to the elevating table main body 58, the peripheral wall portion 60B constituting the peripheral wall of the lower cover 60 is inserted inside the peripheral wall portion 58A of the elevating table main body 58.

The lower cover 60 is screwed from below in a state of being fitted to the lower part of the elevating table main body 58. Specifically, a plurality of screws 76 inserted into each of the screw fixing bosses 60d in the lower cover 60 are screwed into the fixing bosses 58q and 58s of the elevating table main body 58 to raise and lower the lower cover 60. It is fixed to the base body 58.

The bottom surface portion 60a of the lower cover 60 is arranged in parallel with the bottom surface portion 58a with a certain gap. As a result, it is possible to suppress the vertical displacement of the member sandwiched between the bottom surface portion 60a of the lower cover 60 and the bottom surface portion 58a of the elevating table main body 58. For example, the bottom surface portion 60a can suppress the vertical runout of the operating member 59 and the pair of urging members 77. As a result, the operation member 59 can be smoothly moved in the depth direction.

"First locking part"
The first locking portions 70 are provided at both ends of the elevating table 67 in the lateral width direction, respectively.
Hereinafter, an example of the first locking portion 70 arranged on the + X direction side will be described.

As shown in FIG. 10, the first locking portion 70 includes a first holder 71, a locking member 73, an urging member (not shown), and a second holder 75.

The first holder 71 is a rectangular parallelepiped box that opens in the + X direction.
The locking member 73 is inserted into the first holder 71.
The urging member is arranged between the locking member 73 inserted into the first holder 71 in the first locking portion 70 and the second holder 75 described later, and attaches the locking member 73 in the + X direction. Momentum. A compression coil spring can be used as the urging member.

The second holder 75 is fixed to the + X direction end portion of the first holder 71, and constitutes the + X direction end portion of the first locking portion 70.
The second holder 75 has a protrusion 75a and a connecting portion 75f. The outer shape of the protrusion 75a is a chevron shape having a top portion 75b in the protrusion direction when viewed from the + Z direction. The top portion 75b may be a flat surface or a curved surface having a convex arc shape when viewed from the + Z direction.
In the example shown in FIG. 10, the chevron shape of the protrusion 75a is an isosceles triangle, and the top 75b is a curved surface having a convex arc shape.
The inclination of the protrusion 75a is not particularly limited as long as it is equal to or greater than the inclination of the protrusion 59e. In the example shown in FIG. 10, the inclination of the protrusion 75a is substantially equal to the inclination of the protrusion 59e described above.
The connecting portion 75f is a piece that protrudes in the + X direction from both ends of the protruding portion 75a in the depth direction in the Y direction.

As shown in FIGS. 9 and 10, the first locking portion 70 in the assembled state is engaged with a spring (not shown) in an internal space formed by connecting the first holder 71 and the second holder 75. The stopping member 73 and the locking member 73 are housed, and a part of the locking member 73 protrudes from the inside of the first holder 71 in the + X direction (FIG. 10). The position where the amount of protrusion of the locking member 73 in the + X direction is maximum is referred to as the locking position of the first locking portion 70.

The locking member 73 of the first locking portion 70 at the locking position extends to the outside of the elevating table main body 58 through the guide hole portion 58u (FIG. 10) of the elevating table main body 58.

In the present embodiment, a spring and a locking member 73 (not shown) are arranged in series substantially coaxially, and the locking member 73 protruding from the first holder 71 is inserted inside the spring. Therefore, the locking member 73, the first holder 71, and the spring are arranged substantially coaxially with each other.

Here, the operation of the first locking portion 70 and the operating member 59 will be described.
As described above, at the locking position of the first locking portion 70, the positions of the first holder 71 and the second holder 75 in the lateral width direction are fixed. On the other hand, the locking member 73 is urged by the spring inside the first holder 71 and the second holder 75, but can move in the + X direction. Therefore, when the tip of the locking member 73 in the + X direction is pressed in the −X direction with a force larger than the urging force of the spring, the locking member 73 moves in the −X direction, and the tip is inside the guide hole portion 58u. It can be in a state of being retracted to.

When the operating member 59 is pulled in the + Y direction and moved to the unlocked position by the user, the pair of pressing members 59d shown in FIG. 10 moves in the + Y direction against the urging force of the pair of urging members 77. Moving.
When each pressing member 59d moves in the + Y direction, the first locking portion 70 urged toward the pressing member 59d by the urging member 77 moves toward the pressing member 59d, respectively.
When the pressing member 59d retracts from the opening of the second guide portion 58t shown in FIG. 9, each of the first locking portions 70 moves toward the flat plate portion 59g at the same time, and the top portion 75b abuts on the flat plate portion 59g. As a result, in the present embodiment, the locking member 73 protruding from the first holder 71 also translates in the −X direction and retracts inside the guide hole portion 58u. That is, the locking member 73 is retracted to the inside of the guide hole portion 58u in a state of being urged toward the outside in the lateral width direction by the spring.
When the operating member 59 moves to the unlocked position in this way, the first locking portion 70 moves and the tip end portion of each locking member 73 does not protrude from the guide hole portion 58u. In this state, the locking member 73 of each first locking portion 70 cannot be locked to the locking plate 64e of the rail portion 64 (unlockable position).

When the user releases the operation unit 59a, the operation member 59 moves in the −Y direction due to the urging force of the urging member 77, so that the operation member 59 and each first locking portion 70 are in their respective locking positions. Return to. At this time, the operating member 59 that moves by receiving the urging force from the urging member 77 hits the vibration absorbing material 78 without colliding with the member of the elevating table main body 58, for example. The kinetic energy of the operating member 59 is absorbed by the vibration absorbing material 78, and the operating member 59 stops at the locking position. Therefore, the hitting sound due to the impact of the operating member 59 is reduced.

A certain amount of impact force is transmitted to the elevating table main body 58 through the vibration absorbing material 78. In the present embodiment, an external force acts on the elevating table main body 58 due to the expansion and contraction of the urging member 77 and the impact of the operating member 59. The fixing bosses 58s and 58q are provided at positions facing each other of the locking portion 58p and the holding groove 58v on which the external force acts in the direction of the external force. Therefore, by screwing the lower cover 60 with the fixing bosses 58s and 58q, a reinforcing structure that efficiently resists external force can be obtained. As a result, even if an external force such as an impact force is transmitted to the elevating table main body 58 to some extent, the vibration is suppressed, so that a stable operation feeling can be obtained.

In the present embodiment, the locking member 73 projects to the outside of the guide hole portion 58u at the locking position, and retracts to the inside of the guide hole portion 58u depending on the external force acting on the locking member 73. Similarly, when the operating member 59 moves to the unlocked position, the entire first locking portion 70 moves in parallel and moves to the unlockable position.

Next, the locking structure when the upper door accommodating case 56A is attached to the refrigerating room door 12 will be described. The upper door accommodating case 56A will be described as an example, but the same applies to the middle door accommodating case 56B.
As shown in FIG. 2, the upper door accommodating case 56A is provided with respect to the locking plate 64e at a predetermined position among the plurality of locking plates 64e provided in the vertical direction of the pair of rail portions 64 shown in FIG. It is mounted at a predetermined position on the rail portion 64 in a state of being locked from the upper side.
As shown in FIG. 6, when the operating member 59 arranged on the bottom surface side of the upper door accommodating case 56A is in the locked position, through a pair of guide hole portions 58u provided on both sides of the elevating table main body 58 in the width direction. The main body portion 73a of each locking member 73 projects outward in the Y direction of the elevating base main body 58. The main body portion 73a of the locking member 73 is locked to the locking plate 64e at a predetermined position on the rail portion 64 from above. Due to the gravity of the upper door accommodating case 56A, the lower surface of each locking member 73 on the distal end side is pressed against the locking surface 64i of the predetermined locking plate 64e in the rail portion 64.

The locking projection 58EL on the −X direction side in the lateral width direction of the lift main body 58 is inserted into the stopper insertion groove g1 on the −Y direction side of the rail portion 64 in the side rib 61D, and together with the guide portion 58F, the rail is described above. The portion 64 is sandwiched in the depth direction.
The locking projection 58ER on the + X direction side in the lateral width direction of the elevator body 58 is inserted into the stopper insertion groove g2 on the −Y direction side of the rail portion 64 in the side rib 61C, and together with the guide portion 58F, the rail portion. 64 is sandwiched in the depth direction.

Since the center of gravity of the upper door accommodating case 56A is closer to the refrigerating chamber 27 side (+ Y direction) than the rail portion 64, the upper side of the plate-shaped portion 58Aa on the + Y direction side of the locking projections 58ER and EL has the second rail portion 64b. The refrigerating chamber 27 (+ Y direction) side is pressed, and the lower side of the plate-shaped portion 58Aa on the −Y direction side presses 53ct (FIG. 3) toward the inner surface 53a (−Y direction) side.
The upper door accommodating case 56A when attached to the rail portion 64 cannot be pulled out to the refrigerating chamber 27 side, and the descent in the −Z direction is suppressed.

In the present embodiment, the user can move the upper door accommodating case 56A and the middle door accommodating case 56B in the vertical direction by performing each of the operations described below.

(Upward movement: Push-up operation)
In order to move the upper door accommodating case 56A and the middle door accommodating case 56B upward, a push-up operation is performed.
The push-up operation is an operation in which the user applies an upward force to the upper door accommodating case 56A or the middle door accommodating case 56B to move the upper door accommodating case 56B in the + Z direction. The user may apply force to any part of the upper door accommodating case 56A or the middle door accommodating case 56B, but when the user puts his / her hand on the lower surface of the elevating table 67 and pushes up the upper door accommodating case 56A or the middle door accommodating case 56B, the first 1 Since an upward force can be applied near the locking position of the locking portion 70, smoother operation is possible.

When pushing up the lower surface of the lift 67, for example, compared to the case where the upper end of the upper door accommodating case 56A or the middle door accommodating case 56B is gripped and lifted, it is easier to apply force, and even a short user can use the upper door accommodating case. The 56A or the middle door accommodating case 56B can be easily moved upward.

In the locking structure of the present embodiment, there is no member for locking the upper door accommodating case 56A or the middle door accommodating case 56B from above, so that the user can apply an upward force to the upper door accommodating case 56A or the middle door accommodating case 56B. Is added, the upper door accommodating case 56A or the middle door accommodating case 56B can rise along the rail portion 64.

When the locking member 73 rises to the position of the closest locking plate 64e on the rail portion 64, the locking member 73 and the locking plate 64e come into contact with each other and are locked by the horizontal component of the reaction from the locking plate 64e. The member 73 is pushed inward and can get over the locking plate 64e that has come into contact with it.

When the locking member 73 exceeds the abutting locking plate 64e and reaches the upper side thereof, the reaction of pushing the locking member 73 from the rail portion 64 disappears, so that the locking member 73 guides the elevator body 58. It protrudes outward from the hole 58u. At this time, if the user releases the hand and stops the push-up operation, the locking member 73 is locked to the overcoming locking plate 64e from above.

By such a push-up operation, the user moves the upper door accommodating case 56A or the middle door accommodating case 56B upward, and with respect to the upper locking plate 64e, the upper door accommodating case 56A and the middle door accommodating case 56B. Can be locked. As a result, the upper door accommodating case 56A and the middle door accommodating case 56B can be respectively locked to arbitrary locking plates 64e having the same vertical position in the pair of rail portions 64 facing each other in the horizontal direction.

In the push-up operation, the upper door accommodating case 56A can be locked to the upper side, but the upper door accommodating case 56A cannot be lowered. Therefore, for example, even if the hand is removed before reaching the upper side of the upper locking plate 64e, the locking member 73 is surely locked on the nearest lower locking plate 64e. Therefore, in the push-up operation, the upper door accommodating case 56A is prevented from falling.

(Downward movement: unlocking operation)
The locking release operation is an operation for forcibly releasing the locking of the rail portion 64 in the vertical direction by the locking member 73.
In this operation, the user operates the operation member 59 to move the operation member 59 to the unlocked position. For example, the user manually holds the operation unit 59a and the lower end of the front end plate portion 58b of the elevating table main body 58 in the depth direction to move the operation member 59 in the + Y direction. In the present embodiment, when the operating portion 59a is closest to the front end plate portion 58b, the operating member 59 moves to the unlocked position.

At the unlocking position, the pair of locking members 73 retract into the inside of the elevating table main body 58, so that the locking of each locking member 73 with respect to the pair of rail portions 64 is simultaneously released.
When the user releases the grip between the operation unit 59a and the lower end of the front end plate portion 58b of the elevating table main body 58 at the moving destination, the locking member 73 is moved to the second wall portion 58dR by the urging force of the urging member 77. Since it protrudes to the outside, the locking member 73 protrudes into the recess on the upper side of the nearest lower locking plate 64e. By releasing the hand in this state, the locking member 73 is locked on the lower locking plate 64e closest to the moving destination.

By such an unlocking operation, the user moves the upper door accommodating case 56A and the middle door accommodating case 56B downward, and the upper door accommodating case 56A and the middle door accommodating case 56A and the middle door accommodating case 56A and the middle door accommodating case 56A with respect to the lower locking plate 64e. The storage case 56B can be locked. As a result, the upper door accommodating case 56A and the middle door accommodating case 56B can be respectively locked to arbitrary locking plates 64e having the same vertical position in the pair of rail portions 64 facing each other in the horizontal direction.

In this way, the user can freely move the upper door accommodating case 56A and the middle door accommodating case 56B individually in the vertical direction within the movable range of the upper door accommodating case 56A and the middle door accommodating case 56B. Can be made to.

According to the upper door accommodating case 56A and the middle door accommodating case 56B of the present embodiment, the user can easily perform either the push-up operation or the unlocking operation with one hand in front of the upper door accommodating case 56A and the middle door accommodating case 56B. The upper door accommodating case 56A and the middle door accommodating case 56B can be moved by any operation.

Here, the movable range of the upper door accommodating case 56A and the middle door accommodating case 56B will be described.
FIG. 12 is a side view showing how the distance between the upper door storage case 56A and the middle door storage case 56B arranged vertically is regulated by the space regulation stopper 58Ac.

The upper limit position of the upper door accommodating case 56A in the present embodiment is regulated by the upper end plate 64g of the rail portion 64. The position of the upper door accommodating case 56A locked with respect to the uppermost locking plate 64e located directly below the upper end plate 64g of the rail portion 64 is the upper limit of movement upward.

The lower limit position of the upper door accommodating case 56A is regulated by a pair of spacing restricting stoppers 58Ac on the upper door accommodating case 56A side. That is, when the upper door accommodating case 56A is lowered, each interval regulation stopper 58Ac is attached to each upper end surface (stopper receiving surface 58aR, 58aL) of the locking projections 58ER and EL of the middle door accommodating case 56B located directly below. By abutting, movement below it is restricted. Therefore, the lower limit position of the upper door accommodating case 56A changes depending on the position of the middle door accommodating case 56B.

On the other hand, the moving range of the middle door accommodating case 56B in the present embodiment is set by, for example, the position of the upper door accommodating case 56A and the lowering position regulating unit 53d.
The upper limit position of the middle door accommodating case 56B changes depending on the position of the upper door accommodating case 56A. That is, when the middle door accommodating case 56B is raised, the upper end surfaces (stopper receiving surfaces 58aR, 58aL) of the pair of locking projections 58ER and EL of the intermediate door accommodating case 56B are in the upper door accommodating at a predetermined position. By abutting the lower end surfaces 58bL, 58bR of the pair of locking projections 58EL, ER (interval regulation stopper 58Ac) of the case 56A, the movement upward thereof is restricted.

The lowest position of the middle door accommodating case 56B is a position where the lower ends of the locking projections 58ER and EL are locked to the lowering position regulating portion 53d from above. When the locking projections 58ER and EL in the middle door accommodating case 56B are at the lowest position locked to each lowering position regulating portion 53d located on the lower end side of the pair of rail portions 64, the middle door accommodating case 56B and the lower door The vertical distance from the storage case 56C is such that the space regulation stopper 58Ac of the upper door storage case 56A is in contact with the middle door storage case 56B, and the upper door storage case 56A and the middle door storage case 56B are the most. The distance is the same as or larger than the distance when they are in close proximity.

In this way, the lower door accommodating case 56B is restricted from moving downward by the descending position restricting unit 53d.

Also in the middle door accommodating case 56B, the pair of locking projections 58EL and ER (each spacing regulation stopper 58Ac) provided on both sides of the elevating table main body 58 in the lateral width direction are stoppers on the -Y direction side of the rail portion 64. It is inserted into the insertion grooves g1 and g2 and becomes a hidden state.

Further, in the present embodiment, as shown in FIG. 12, the vertical length h2 (FIGS. 7 and 8) of the locking projections 58EL and 58ER is the raised ridge 57i and the upper rib of the upper door accommodating case 56A. It is larger than the vertical distance of the gap G1 between the position where the lower surface 61g of the 61F abuts and the upper end of the rail portion 64 (hereinafter, the gap distance L). Therefore, the upper door accommodating case 56A in which the case body 57 is placed on the elevating table 67 cannot pass through the gap G1 in the + Y direction. With this configuration, it is possible to prevent the upper door accommodating case 56A from coming off from the rail portion 64 even if momentum is gained during the push-up operation.
On the other hand, if only the elevating table 67 is used with the case body 57 removed, the elevating table 67 can be tilted diagonally to pass through the gap G1. Therefore, when mounting the upper door accommodating case 56A, it can be mounted by first mounting only the elevating table 67 to each rail portion 64.

As described above, in the upper door accommodating case 56A of the present embodiment, the movement of the upper door accommodating case 56A is restricted downward because the pair of spacing restricting stoppers 58Ac abuts on the stopper receiving surfaces 58aR and 58aL of the middle door accommodating case 56B. The distance from the middle door storage case 56B located in is restricted. As a result, a predetermined gap U is formed between the upper door accommodating case 56A and the middle door accommodating case 56B, and when the upper door accommodating case 56A is lowered, the upper door accommodating case 56A is increased by the weight of the contained object. It is possible to prevent the middle door accommodating case 56B from being too close. This prevents the user from pinching his or her hand or finger between the upper door accommodating case 56A and the middle door accommodating case 56B. The size of the gap U formed between the upper door accommodating case 56A and the middle door accommodating case 56B changes the vertical extension length h1 (FIG. 9) of the space limiting stopper 58Ac in the upper door accommodating case 56A. It can be changed as appropriate.

Actually, as shown in FIGS. 7, 8 and 12, the gap U has an extension length h1 (lower end of the peripheral wall portion 58A) of each spacing regulation stopper 58Ac in the locking projections 58EL and ER of the upper door accommodating case 56A. (Length from to the lower end surface 58bL, 58bR of the locking protrusion EL, ER) and the protrusion length h0 on the upper end side of the locking protrusion 58EL, ER of the middle door accommodating case 56B (locking protrusion from the upper end of the peripheral wall portion 58A). The length h4 is the sum of the upper end surface of each interval regulation stopper 58Ac in EL and ER and the length up to the stopper receiving surfaces 58aR and 58aL).

Further, the pair of locking projections 58EL and ER (each spacing restriction stopper 58Ac) in the upper door accommodating case 56A and the middle door accommodating case 56B are located in the stopper insertion grooves g1 and g2 on the −Y direction side of the rail portion 64, respectively. Since it is inserted, it is hidden behind each rail portion 64 when viewed from the + Y direction side. Therefore, it is difficult for the user to see each interval regulation stopper 58Ac, and the design is improved.

Further, it is prevented that each interval regulation stopper 58Ac on the upper door accommodating case 56A side becomes an obstacle when taking out or accommodating the contained items contained in the middle door accommodating case 56B, and the contained items and the user to be taken in and out. It is possible to prevent the hand or the like from coming into contact with each interval regulating stopper 58Ac.

Further, each spacing regulation stopper 58Ac on the upper door accommodating case 56A side is configured to abut on the upper end surfaces (stopper receiving surfaces 58aR, 58aL) of the locking projections 58EL and ER of the middle door accommodating case 56B. For this reason, each spacing regulation stopper 58Ac on the upper door accommodating case 56A side does not directly contact the upper end of the case main body 57 of the middle door accommodating case 56B or the peripheral wall portion 58A of the elevating table main body 58, so that the case main body 57 and It is possible to prevent the elevator body 58 from being scratched or damaged.

Further, since the stopper receiving surfaces 58aR and 58aL project in the + Z direction from the upper ends of the peripheral wall portions 58A of the case main body 57 and the elevating base main body 58, when the spacing regulation stopper 58Ac abuts on the stopper receiving surfaces 58aR and 58aL. The impact is less likely to be transmitted to the peripheral wall portion 58A of the case main body 57 and the elevating table main body 58, and it is possible to further prevent the peripheral wall portion 58A of the case main body 57 and the elevating table main body 58 from being damaged.

In addition, since the pair of spacing regulation stoppers 58Ac enables both prevention of finger pinching and regulation of the lower limit position, it is not necessary to provide separate protrusions in order to obtain each effect, and the number of protrusions can be reduced by the user. Can eliminate the obstacles when using.

Although one embodiment of the present invention has been described above, it is presented as an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and variations thereof are included in the scope of the invention described in the claims and the equivalent scope thereof, as are included in the scope and gist of the invention.

The space between the door storage cases 56A and 56B arranged one above the other can be regulated to a predetermined space, and if the configuration is arranged on the back side (-Y direction side) of the rail portion 64, the space regulation stopper 58Ac It is possible to change the number, shape, etc. of the doors as appropriate.

FIG. 13 is a side view showing a modified example of the elevating table main body (interval regulation stopper 58Ac).
For example, as shown in FIG. 13, the middle door accommodating case 56B may be configured to include an interval regulating stopper 58Ac protruding in each of the vertical directions of the elevating table main body 58.
The locking projections 58EL and ER are extended so as to protrude outward in the Z direction from the upper and lower ends of the peripheral wall portion 58A in the elevator body 58, and the portions protruding upward from the upper end of the peripheral wall portion 58A are spaced upward. As a configuration that regulates the distance between the door accommodating cases 56A and 56B arranged vertically by functioning as the regulation stopper 58Ac and the portion protruding downward from the lower end of the peripheral wall portion 58A as the space regulation stopper 58Ac on the lower side. May be good.

For example, the spacing restricting stopper 58Ac may have a cushioning material on the tip end (upper end or lower end) side in the vertical direction thereof for cushioning an impact when it comes into contact with another door accommodating case.

Further, for example, the interval regulation stopper 58Ac may be provided on the lower cover 60 instead of being provided on the elevating table main body 58. By providing the interval regulation stopper 58Ac on the lower cover 60, when the interval regulation stopper 58Ac is damaged, the lower cover 60 only needs to be replaced, so that the replacement work is easy and the cost can be reduced.

Further, for example, in order to secure further strength of the interval regulation stopper 58Ac, it may have a solid shape.

According to one embodiment described above, a refrigerator including a refrigerator main body including a storage chamber, a door that can open and close the storage chamber, and a plurality of door storage cases arranged vertically inside the door. In, at least one of the plurality of door accommodating cases has an elevating table, and the elevating table releases a locking member that locks to the door and a locking member that locks the locking member to the door. A locking release mechanism, an elevating table that can move up and down along a pair of rails provided on both sides of the door in the width direction, and a protrusion toward the other door accommodating case arranged in the up and down direction.
