Description

Refrigerator with a door

Priority is claimed in the present application based on Japanese patent application No. 2020-207846, filed on the sun at 12/15/2020, and the contents of which are incorporated herein by reference.

Technical Field

Embodiments of the present invention relate to a refrigerator.

Background

A door container is known in which a door of a storage room in a refrigerator is provided so as to be movable in a vertical direction and attachable to and detachable from the door. For example, a locking mechanism that locks with the door and an operation member that operates the locking mechanism are provided on the bottom surface of the door container.

However, in the case of a refrigerator having a swing door, corners of a door container on the opposite side of a hinge need to be rounded according to a radius of rotation of the swing door. This reduces the area of the bottom surface portion on which the operation member is provided, and therefore, the size of the operation member is restricted. If the operating member is small, the locking mechanism may not be easily operated.

[ embodiment 1 ]

A refrigerator according to embodiment 1 will be described.

Fig. 1 is a front view of a refrigerator according to embodiment 1 showing a state where a door is opened. The overall configuration of a refrigerator 1A according to embodiment 1 shown in fig. 1 will be described. However, the refrigerator 1A does not need to have all the configurations described below, and some of the configurations may be omitted as appropriate.

The refrigerator 1A includes, for example, a cabinet 10, a pair of refrigerating chamber doors 12 and 13 (door, revolving door), and a plurality of doors 11.

The box 10 includes, for example, an inner box, an outer box, and an insulating material.

The inner box is made of, for example, synthetic resin, and has a shape recessed from the front side toward the rear side at a plurality of locations. Each recess of the inner box forms a plurality of storage compartments 27. In the example shown in fig. 1, the plurality of storage compartments 27 include a refrigerating compartment 27A, a vegetable compartment 27B, an upper freezing compartment 27C, a lower freezing compartment 27D, and an ice making compartment 27E. Refrigerating room 27A, vegetable room 27B, upper freezing room 27C, and lower freezing room 27D are arranged in this order from the upper side toward the lower side. The ice making chamber 27E is located at the left side of the upper freezing chamber 27C.

The box 10 has openings at the front side of the storage chambers 27, through which foodstuffs can be taken out of or put into the storage chambers 27.

The outer box is a rectangular parallelepiped shape having three outer surface portions except for the front side of the casing 10. The outer box is formed of, for example, metal or a composite material of metal and resin.

The heat insulating material is a foamed heat insulating material such as foamed polyurethane, for example, and is filled between the inner box and the outer box. Thus, the case 10 has heat insulation properties.

In the casing 10, various components forming the refrigerator main body 5 together with the casing 10 are disposed between the inner box and the outer box. Examples of the components forming the refrigerator main body 5 include a cooling unit that forms cold air, a flow path forming member that forms a flow path that circulates the cold air between each storage chamber 27 and the cooling unit, a cooling fan that delivers the cold air to each storage chamber 27 through the flow path, and a control board that controls the operation of the cooling unit and the cooling fan.

The temperature in refrigerating compartment 27A is maintained at a temperature lower than that of vegetable compartment 27B and higher than that of upper freezing compartment 27C and lower freezing compartment 27D. In the interior of refrigerating room 27A, for example, a shelf in a partitioned room, a chilling chamber container, and the like are disposed. The front surface of refrigerating room 27A is openably and closably covered by refrigerating room doors 12 and 13 opened to the left and right.

As shown in fig. 1, refrigerating compartment doors 12 and 13 are doors provided to open and close refrigerating compartment 27A. The refrigerating chamber door 12 covers the left side of the opening of the refrigerating chamber 27A when closed. The refrigerating chamber door 13 covers the right side of the opening of the refrigerating chamber 27A when closed. The end portion in the + X direction of the refrigerating chamber door 12 and the end portion in the-X direction of the refrigerating chamber door 13 are opposed to each other with a slight gap in the lateral width direction when closed. The gap in the closing time between the refrigerating compartment doors 12, 13 in the lateral width direction is closed by, for example, a rotating partition plate 68 provided to the refrigerating compartment door 12.

The width dimensions of the refrigerating compartment doors 12 and 13 in the lateral width direction may be the same or different from each other. In the example shown in fig. 1, the width dimensions are different from each other, and the width dimension of the refrigerating compartment door 12 is smaller than the width dimension of the refrigerating compartment door 13.

The refrigerating chamber door 12 is coupled to the end of the casing 10 in the-X direction by a pair of hinges 32 provided at the upper and lower ends in the-X direction, respectively. The refrigerating chamber door 12 can be rotated about the axis O of rotation of the hinge 32 extending in the up-down direction_LRotating in the horizontal plane for the center.

The refrigerating chamber door 13 is coupled to the end of the casing 10 in the + X direction by a pair of hinges 33 provided at the upper and lower ends in the + X direction, for example. The refrigerating chamber door 13 can be rotated about the axis O of rotation of the hinge 33 extending in the vertical direction_RRotating in a horizontal plane for the center.

Thus, the refrigerating chamber doors 12 and 13 are split rotary doors (split rotary doors) that rotate to open to the left and right. The user can open the refrigerating chamber doors 12 and 13 to the left and right while rotating them by putting his or her hands on the grooves 8 provided on the lower end sides of the refrigerating chamber doors 12 and 13 and pulling them forward.

In the example shown in fig. 1, the radius of rotation r of the end of the refrigerating compartment door 12 in the + X direction_LIs smaller than the radius r of rotation of the end in the-X direction of the refrigerating chamber door 13_R。

The swing door that is opened in the left-right direction is sometimes called a side-by-side door, a french door (french door), or the like.

The plurality of doors 11 are doors provided to open and close the vegetable compartment 27B, the upper freezer compartment 27C, the lower freezer compartment 27D, and the ice making compartment 27E. The vegetable compartment door 11B, the upper freezing compartment door 11C, the lower freezing compartment door 11D, and the ice-making compartment door 11E cover respective front surfaces of the vegetable compartment 27B, the upper freezing compartment 27C, the lower freezing compartment 27D, and the ice-making compartment 27E.

The temperature in vegetable compartment 27B is maintained at a higher temperature than in refrigerating compartment 27A. In the vegetable compartment 27B, for example, a vegetable compartment container for storing stored items such as vegetables and a guide rail for moving the vegetable compartment container in the depth direction are provided.

The front surface of the vegetable room 27B is openably and closably covered by a drawer-type vegetable room door 11B.

The temperatures in the upper freezer compartment 27C, the lower freezer compartment 27D, and the ice making compartment 27E are maintained at temperatures at which the stored materials can be frozen. Inside upper freezer compartment 27C, lower freezer compartment 27D, and ice making compartment 27E, for example, a small freezer compartment, a freezer compartment container that stores stored items to be frozen and stored, and a guide rail for moving the freezer compartment container in the depth direction are provided.

The front surfaces of upper freezer compartment 27C, lower freezer compartment 27D, and ice making compartment 27E are openably and closably covered by drawer-type upper freezer compartment door 11C, lower freezer compartment door 11D, and ice making compartment door 11E.

The above-described configurations of the storage chambers 27 and the doors 11 are examples, and are not limited to the above-described examples. For example, door 11 of storage room 27 other than refrigerating room 27A may be a revolving door or a split revolving door.

As shown in fig. 1 when the refrigerating chamber doors 12 and 13 are opened, a plurality of door containers are disposed inside the refrigerating chamber doors 12 and 13, respectively.

For example, door containers 56B and 56A and a lower door container 56C are arranged in this order in the-Z direction inside the refrigerating chamber door 12. For example, door containers 54B and 54A and a lower door container 54C are arranged in this order in the-Z direction inside the refrigerating chamber door 13. However, the number of door containers in each of the refrigerating compartment doors 12 and 13 in the present embodiment is not limited to this. For example, 1 door container may be disposed in each of the refrigerating chamber doors 12 and 13, or 4 or more door containers may be disposed therein.

The door containers 56A and 56B disposed above the lower door container 56C are attached to the inner surface portion forming the inner surface in the + Y direction of the refrigerating chamber door 12 so as to be movable in the vertical direction and attachable and detachable. The door containers 56A and 56B can be fixed in position in the vertical direction at a plurality of positions within the vertical movement range.

Here, the vertical movement pitch and the movement range of the door containers 56A and 56B are not particularly limited.

The lower door container 56C may be detachable from the inner surface portion of the refrigerating compartment door 12, or may be fixed to the inner surface portion.

The door containers 54A and 54B disposed above the lower door container 54C are attached to the inner surface portion forming the inner surface in the + Y direction of the refrigerating chamber door 13 so as to be movable in the vertical direction and detachable. The door containers 54A and 54B can be fixed in position in the vertical direction at a plurality of positions within the vertical movement range.

Here, the vertical movement pitch and the movement range of the door containers 54A and 54B are not particularly limited.

The lower door container 54C may be detachable from the inner surface portion of the refrigerating chamber door 13, or may be fixed to the inner surface portion.

Next, the detailed structure of the refrigerating compartment doors 12 and 13 will be described. However, since the basic structures of the refrigerating compartment doors 12 and 13 are the same except for the difference in the arrangement position and the lateral width dimension, the following description will be centered on an example of the refrigerating compartment door 12.

Fig. 2 is a perspective view showing the refrigerating compartment door 12 of embodiment 1.

As shown in fig. 2, the refrigerating compartment door 12 includes, for example, an outer profile member 50A, a gasket 55A, and a rotating partition plate 68.

The outer profile member 50A is formed in a box shape. The "box-like" in this specification also includes a flat box-like shape. The outer contour member 50A includes, for example, a frame 51A, a front surface plate 52A, and a rear surface member 53A (inner surface portion).

The frame body 51A is a rectangular frame as viewed from the-Y direction. The frame 51A includes an upper member 51A, a lower member 51b, and side members 51c and 51 d. The upper member 51a is plate-shaped along the lateral width direction and the depth direction in a state where the refrigerating compartment door 12 is closed, and forms an upper surface of the refrigerating compartment door 12. The lower member 51b is plate-shaped along the lateral width direction and the depth direction, and forms the lower surface of the refrigerating chamber door 12. The side members 51c and 51d are plate-shaped along the vertical direction and the depth direction. The side member 51c forms a side surface in the + X direction. The side member 51d forms a side surface in the-X direction.

The frame 51A is made of, for example, synthetic resin.

The lower member 51b has a groove 8 recessed in the + Z direction. The groove 8 is formed at the end of the lower side member 51b in the + X direction. The groove portion 8 can be used for a user to take when opening the refrigerating chamber door 12.

The front surface plates 52A are attached to close the openings of the frame 51A in the-Y direction and are located at the front end portions of the refrigerating compartment doors 12. The front panel 52A is a rectangular plate member along the frame 51A, and forms the front surface of the refrigerating chamber door 12. The front surface plate 52A is, for example, a glass plate. However, the front surface plate 52A is not limited to a glass plate, and may be formed of a synthetic resin or other material. The front surface plate 52A may be a flat plate or a curved plate. Hereinafter, an example in which the front surface plate 52A is a flat plate will be described.

The rear surface member 53A is attached to the frame 51A from the opposite side to the front surface plate 52A, and is positioned at the rear end portion of the refrigerating compartment door 12. The outer shape of the rear surface member 53A viewed from the-Y direction is a rectangle along the frame body 51A. The rear surface member 53A is made of, for example, a synthetic resin.

The rear surface member 53A has a planar inner surface 53A facing the + Y direction, and a rib 61 projecting from the outer peripheral edge of the inner surface 53A in the + Y direction.

Rib 61 protrudes in the + Y direction toward refrigerating compartment 27A from frame 51A and inner surface 53a in a state where refrigerating compartment door 12 closes the opening of refrigerating compartment 27A (at the time of closing). The space between the rear surface member 53A and the front surface plate 52A and the inside of the convex shape of the rib 61 are filled with a foam heat insulating material.

The rib 61 is provided mainly for suppressing escape of cold air in the refrigerating compartment 27A from a gap between the refrigerating compartment door 12 and the casing 10.

The term "rib" in the present specification is a name for convenience of description, and broadly means a portion projecting rearward from the rear surface member 53A, and is not limited to a specific shape or function.

Gasket 55A is provided to seal refrigerating compartment 27A so that cold air in refrigerating compartment 27A does not leak to the outside from between refrigerating compartment door 12 and casing 10 when refrigerating compartment door 12 is closed.

The gasket 55A is formed in a ring shape surrounding the outer periphery of the frame 51A, and is attached to the rear surface member 53A. The method of attaching the gasket 55A is not particularly limited. For example, the gasket 55A may be attached by a concave-convex fitting between a convex portion provided in the gasket 55A for attachment and a concave portion provided in the rear surface member 53A for attachment.

The rotating partition plate 68 extends in the up-down direction along the gasket 55A in the + Y direction of the gasket 55A abutting the side member 51c of the refrigerating compartment door 12. The upper and lower ends of the swivel partition plate 68 are rotatably coupled to the rear surface member 53A in a horizontal plane via a swivel support member, not shown.

When the refrigerating compartment door 12 shown in fig. 2 is opened, the rotating partition plate 68 rotates toward the rib 61 near the side member 51c and is positioned closer to the-X direction than the side member 51c when viewed from the-Y direction.

When the refrigerating compartment door 12 is closed, the rotary partition plate 68 is rotated clockwise as viewed from the-Z direction and protrudes in the + X direction from the side member 51 c. This forms a flat plate portion where the gasket 55A and a gasket 55B, described later, of the refrigerating compartment door 13 can be brought into close contact with each other.

Here, the detailed configuration of the rear surface member 53A will be described.

Fig. 3 is a perspective view showing a rear surface part 53A of the refrigerating chamber door 12.

As shown in fig. 3, the rib 61 has a rib 61F extending in the lateral width direction along the upper member 51a, a rib 61G extending in the lateral width direction along the lower member 51b, a rib 61C extending in the up-down direction along the side member 51C, and a rib 61D extending in the up-down direction along the side member 51D. The ribs 61F, 61G are equal in length in the lateral width direction. The ribs 61C and 61D have the same vertical length.

The ribs 61C, 61D, and 61G protrude in the + Y direction from the rib 61F. The amount of protrusion of the rib 61F is as follows: when the door cases 56A, 56B move in the + Z direction, the door cases 56A, 56B can be prevented from coming out.

The rib 61C has a side surface S1 facing the-X direction. The rib 61D has a side surface S2 facing the + X direction. Each of the side surfaces S1 and S2 is a plane substantially perpendicular to the inner surface 53 a. The side surfaces S1 and S2 face each other in the lateral width direction.

The side surface S1 of the rib 61C is provided with a step portion 53C, a rail portion 64, and a locking protrusion 65.

The step portion 53c protrudes from the side surface S1 in the-X direction and extends from the lower surface 61g (see fig. 2) of the rib 61F in the-Z direction.

The rail portion 64 guides the door containers 56A and 56B in the up-down direction while restricting the position in the depth direction when moving the door containers 56A and 56B in the up-down direction, which will be described later.

The rail portion 64 protrudes from the side surface S1 in the-X direction, is spaced apart from the end surface 53cy of the stepped portion 53c in the + Y direction, and extends vertically in parallel with the end surface 53 cy.

The protruding height of the rail portion 64 protruding from the side surface S1 may be different from or the same as the protruding height of the step portion 53 c. For example, the projection height of the rail portion 64 may be lower than the projection height of the end face 53cx, which is the end face of the step portion 53c in the-X direction. In this case, the end surface 53cx of the step portion 53c is close to the side surface in the + X direction of the door containers 56A and 56B described later, and can function as a guide surface in the lateral width direction of the door containers 56A and 56B.

A groove g1 extending in the vertical direction is formed between the rail portion 64 and the end surface 53 cy.

The groove g1 has a constant groove width, except that the width is narrowed by the convex portion p bulging from the step portion 53c near the upper end of the rail portion 64. In the case where a space for disposing the member can be secured inside the rib 61C, the convex portion p may be eliminated.

The upper end of the rail portion 64 is formed at a position lower than the upper end of the rib 61C. Therefore, a gap G1 is formed between the upper end of the rail portion 64 and the rib 61F when viewed from the-Y direction.

The lower end of the rail portion 64 and the lower end of the step portion 53c are formed at the same position in the up-down direction. A descending-position restricting portion 53d that protrudes inward of the groove g1 is provided between the lower end of the rail portion 64 and the lower end of the stepped portion 53 c. The lowering position regulating portion 53d is provided to regulate the lowering position of the door container 56B.

The shape of the lowering position regulating portion 53d is not particularly limited as long as the lowering position of the door container 56B can be regulated. In the example shown in fig. 3, the lowered position restricting portion 53d is a plate connecting the lower end of the rail portion 64 and the end surface 53cy of the stepped portion 53c, and closes the groove g1 from below.

The vertical position of the lowering position regulating portion 53d is an appropriate position corresponding to the maximum lowering position of the door case 56B.

A reinforcing rib 64fb for reinforcing the descending position regulating portion 53d against an external force acting from above is provided between the lower surface of the descending position regulating portion 53d and the side surface S1.

The track portion 64 includes a1 st track portion 64a and a2 nd track portion 64b in this order in the + Z direction.

The 1 st rail portion 64a guides vertical movement of the door containers 56A, 56B described later, and regulates vertical movement positions of the door containers 56A, 56B in multiple stages.

The 1 st rail portion 64a has a1 st guide portion 64c, a2 nd guide portion 64d, a plurality of catching plates 64e, an upper end plate 64g, a lower end plate 64k, and a plurality of inclined ribs 64 fa.

The 1 st guide portion 64c forms the side of the rail portion 64 in the-Y direction. The 1 st guide portion 64c is a flat plate that protrudes from the side surface S1 in the-X direction and extends in the up-down direction. The 1 st guide portion 64c extends to the 2 nd rail portion 64 b.

The 2 nd guide portion 64d forms a side surface of the rail portion 64 in the + Y direction. The 2 nd guide portion 64d is a flat plate that protrudes from the side surface S1 toward the-X direction and extends in the up-down direction. The 2 nd guide portion 64d is parallel to the 1 st guide portion 64 c. The 2 nd guide portion 64d is the same as the 1 st guide portion 64c, and extends to the 2 nd rail portion 64 b.

the-X direction distal ends of the 1 st guide portion 64c and the 2 nd guide portion 64d are located on the same plane orthogonal to the depth direction.

The plurality of locking plates 64e extend in the depth direction between the 1 st guide portion 64c and the 2 nd guide portion 64d, and protrude from the side surface S1 in the-X direction. The plurality of catching plates 64e are provided to be separated from each other in the up-down direction from the lower ends of the 1 st guide portion 64c and the 2 nd guide portion 64d to the upper end of the 1 st rail portion 64 a. The pitch in the up-down direction of each retaining plate 64e may not be constant, but is constant in the example shown in fig. 3. The pitch is not particularly limited, and may be, for example, 10mm to 70mm, and more preferably 10mm to 22 mm.

In the example shown in fig. 3, 17 locking plates 64e are arranged.

The front end of each locking plate 64e in the protruding direction is located on the same plane as the front ends of the 1 st guide portion 64c and the 2 nd guide portion 64d located on both sides of each locking plate 64e in the width direction.

The upper end plate 64g is a plate that extends in the depth direction between the 1 st guide portion 64c and the 2 nd guide portion 64d and that protrudes perpendicularly from the side surface S1. The upper end plate 64g is located above the plurality of locking plates 64e, and is separated upward from the uppermost locking plate 64e at a pitch substantially equal to the pitch between the locking plates 64 e.

The lower end plate 64k is a plate that extends in the depth direction between the 1 st guide portion 64c and the 2 nd guide portion 64d and that protrudes perpendicularly from the side surface S1. The lower end plate 64k is located below the lowermost locking plate 64e, and is spaced downward from the lowermost locking plate 64e at an interval wider than the interval between the locking plates 64 e.

A plurality of inclined ribs 64fa are provided on the lower surface side of each retaining plate 64e except for the lower end plate 64k and on the lower surface side of the upper end plate 64 g. The inclined ribs 64fa are provided in a pair on the lower surface of each of the locking plates 64e and the lower surface of the upper end plate 64g, and are arranged at intervals in the depth direction. Further, the inclined ribs 64fa are also arranged at intervals in the depth direction with respect to the 1 st guide portion 64c and the 2 nd guide portion 64 d.

The shape of each inclined rib 64fa as viewed from the-Y direction is a triangle inclined toward the side surface S1 as going from the respective front ends of the respective locking plates 64e and the upper end plate 64g in the-X direction toward the-Z direction.

With this configuration, a plurality of projections are arranged at substantially equal intervals in the vertical direction from the lower side toward the upper side inside the 1 st rail portion 64 a. The plurality of convex portions are formed by inclined portions 64j formed at the front ends of the inclined ribs 64fa in the-X direction, the front end surfaces of the locking plates 64e, and locking surfaces 64i formed on the upper surfaces of the locking plates 64e and extending in the horizontal direction. Opposing concave portions are formed between the convex portions protruding in the X direction from the side surface S1. Therefore, a zigzag uneven structure in which the inclined portion 64j faces downward is formed inside the 1 st rail portion 64 a.

The locking portions 70 described later are locked from above to the respective locking surfaces 64i in the concave-convex structure of the rail portion 64.

The inclined portions 64j at the lower ends of the plurality of inclined ribs 64fa are inclined so that the locking portions 70 can be pressed toward the door container 56A as the locking portions 70 move upward from the locking surfaces 64i, which will be described later.

The 2 nd rail portion 64b has upper end portions of the 1 st guide portion 64c and the 2 nd guide portion 64d of the 1 st rail portion 64a, and an intermediate rib 64h extending in the up-down direction between the upper end portions.

The intermediate rib 64h is a flat plate parallel to the 1 st and 2 nd guide portions 64c and 64 d. The length of the intermediate rib 64h in the vertical direction is equal to the length from the upper end plate 64g to the upper ends of the 1 st guide portion 64c and the 2 nd guide portion 64 d. The lower end of the intermediate rib 64h is connected to the upper surface of the upper end plate 64 g. The projection height of the intermediate rib 64h in the-X direction is equal to the projection height of the 1 st guide portion 64c and the 2 nd guide portion 64 d.

The locking projection 65 is provided to fix or detachably lock the lower door container 56C. The shape of the locking projection 65 is not particularly limited as long as it can detachably lock the lower door container 56C.

In the example shown in fig. 3, the shape of the locking projection 65 viewed from the + X direction is a substantially rectangular shape that is long in the up-down direction. The locking projection 65 has a width in the depth direction approximately equal to that of the rail portion 64, and is disposed below the rail portion 64. A gap G2 is formed between the lower end of the rail portion 64 and the upper end of the locking projection 65.

The side surface S2 of the rib 61D is provided with a step portion 53c, a rail portion 64, and a locking protrusion 65. The step portion 53c, the rail portion 64, and the locking protrusion 65 on the side surface S2 have the same shapes as the step portion 53c, the rail portion 64, and the locking protrusion 65 on the side surface S1, except that the step portion, the rail portion 64, and the locking protrusion 65 protrude in the + X direction on the side surface S2. Therefore, the step portions 53C, the rail portions 64, and the locking projections 65 in the side surfaces S1 and S2 have the above-described fine portion shapes, and are symmetrical with respect to a plane parallel to a YZ plane that bisects the distance between the ribs 61C and 61D. However, in the present embodiment, since the convex portion p is not formed at the step portion 53c in the side surface S2, the groove width of the concave groove g1 in the side surface S2 is constant in the vertical direction.

As shown in fig. 1, the refrigerating compartment door 13 includes an outer contour member 50B and a gasket 55B instead of the outer contour member 50A and the gasket 55A of the refrigerating compartment door 12.

The outer contour member 50B includes a frame body 51B, a front panel 52B, and a rear surface member 53B (inner surface portion) instead of the frame body 51A, the front panel 52A, and the rear surface member 53A.

The housing 51B is the same as the housing 51A except that the transverse width dimension is different and the pivot partition plate is not provided, and the hinge 33 is connected to the end in the + X direction instead of the hinge 32.

The front panel 52B and the rear member 53B are the same as the front panel 52A and the rear member 53A, respectively, except for the difference in the lateral width dimension.

Next, the door containers 56A and 56B will be described. The door containers 56A, 56B may be identical to or different from each other as long as they can be locked to the rear surface member 53A. In the example shown in fig. 1 and 2, the door containers 56A and 56B have the same shape.

Hereinafter, description will be given mainly on an example of the door container 56A.

Fig. 4 is a perspective view showing a door container according to embodiment 1. Fig. 5 is a plan view showing the elevating platform of the door container according to embodiment 1. Fig. 6 is an exploded perspective view showing the door container according to embodiment 1. Fig. 7 is a perspective view of the elevating table main body according to embodiment 1.

As shown in fig. 4, the door container 56A includes a lift table 67 and a container body 57.

The elevating table 67 has a base portion 67a (bottom surface portion) and an upper wall portion 67 b.

The base portion 67a has a horizontally extending flat plate shape, and supports a container body 57 described later from below.

As shown in fig. 5, the outer shape of the base portion 67a in plan view (-Z direction) is a concave polygon close to a rectangle surrounded by edges Eb, Ec, Ef, EeL, eddl, Ek, Em, EeR, and EdR.

The edges Eb and Ec are the respective edges in the + Y direction and the-Y direction, and extend in the lateral width direction. The edge Ec is a straight line extending in the lateral width direction. The edges Eb are preferably also the same straight lines, but need not be strictly straight lines as long as they are nearly straight. For example, the edge Eb may have a curved arcuate shape slightly protruding from a straight line extending in the lateral width direction toward the + Y direction. Hereinafter, for the sake of simplicity, an example will be described in which the edge Eb is a straight line extending in the lateral width direction.

The end of the edge Eb in the-X direction is connected to the end of the edge Ef extending in the-Y direction as a whole in the + Y direction with an arc a1 interposed therebetween. However, the shape of the more detailed edge Ef is slightly inclined toward the-X direction as going toward the-Y direction.

The end of the edge Eb in the + X direction is smoothly connected to a convex arc-shaped edge Ek that advances in the + X direction as it goes in the-Y direction, across an arc a 2.

The end of the edge Ek in the-Y direction and the end of the edge Em extending in the-Y direction as a whole in the + Y direction are smoothly connected with an arc a3 therebetween. However, the shape of the more detailed edge Em is slightly inclined toward the + X direction as going toward the-Y direction.

The end in the-X direction of the edge Ec is smoothly connected to the end in the-Y direction of the edge EdL extending toward the + Y direction. The end in the + X direction of the edge Ec is smoothly connected to the end in the-Y direction of the edge EdR extending in the + Y direction.

An edge EeL extending in the-X direction and connected to an end of the edge Ef in the-Y direction is connected to an end of the edge EdL in the + Y direction.

To an end of the edge EdR in the + Y direction, an edge EeR is connected, which extends in the + X direction and is connected to an end of the edge Em in the-Y direction.

Hereinafter, the whole of the edge Eb, the arc a1, the edge Ef, the edge el, the EdL, the Ec, the EdR, the EeR, the Em, the arc A3, the edge Ek, and the arc a2 may be referred to as a peripheral edge shape E.

The base portion 67a having the outer shape of the peripheral edge E in plan view has a width dimension that is narrowest between edges EdR and EdL and widest between edges Em and Ef. A step protruding outward from the edges ee r, el is formed at the ends of the edges EdR, EdL in the + Y direction.

In the outer shape of the base portion 67a in a plan view, a substantially rectangular narrow width portion 67d sandwiched by edges EdR, EdL and a wide width portion 67c inscribed in a virtual rectangle RA having a wider lateral width than the narrow width portion 67d are arranged in order in the + Y direction.

The end of the wide portion 67c in the + X direction is bent gradually toward the-X direction by the edge Em, the arc A3, the edge Ek, and the arc a 2. Thus, the corners of the wide portion 67c in the + Y direction and the + X direction have a curved shape formed by rounding the corners of the virtual rectangle RA.

On the other hand, at the end of the wide width portion 67c in the-X direction and the + Y direction, a corner portion slightly rounded by a circular arc a1 having a smaller diameter than the circular arc a2 is formed between the edges Eb and Ef forming substantially right angles.

The upper wall portion 67b extends in the + Z direction along the edges EeR, EdR, Ec, EdL, and EeL of the base portion 67a, respectively. Therefore, the top wall 67b has a U-shape that opens in the + Y direction in plan view.

As shown in fig. 4, an end portion in the-Y direction of a container main body 57 described later disposed on the base portion 67a is housed inside the upper wall portion 67 b.

As shown in fig. 6, the lift table 67 includes a lift table main body 58 and a lower cover 60, and a locking portion 70 and an operation member 59 are disposed between the lift table main body 58 and the lower cover 60.

The elevating table main body 58 includes a box portion 58A forming an upper surface and an outer peripheral surface of the base portion 67a, and an upper wall portion 67 b.

As shown in fig. 7, the box portion 58A is box-shaped and open in the-Z direction.

The case portion 58A has an upper surface portion 58A, a3 rd rear wall portion 58b (front surface portion), a front wall portion 58cb, a1 st side wall portion 58dLb (1 st side surface portion), a2 nd side wall portion 58dRb (2 nd side surface portion), a3 rd side wall portion 58f (3 rd side surface portion), a 4 th wall portion 58eLb (1 st step portion), a 5 th wall portion 58eRb (2 nd step portion), a 4 th side wall portion 58m (curved side surface portion), and a 5 th side wall portion 58k (curved side surface portion).

The upper surface portion 58a is a flat plate forming an upper surface of the base portion 67 a. The top surface portion 58a has a peripheral edge shape E in plan view.

The 3 rd rear wall portion 58b, the front wall portion 58cb, the 1 st side wall portion 58dLb, the 2 nd side wall portion 58dRb, the 3 rd side wall portion 58f, the 4 th wall portion 58eLb, the 5 th wall portion 58eRb, the 4 th side wall portion 58m, and the 5 th side wall portion 58k are walls extending from the peripheral edge of the upper surface portion 58a by the same distance in the-Z direction along the edges Eb, Ec, edd, EdR, Ef, EeL, ee, Em, Ek, respectively.

The 1 st end e1, which is the end of the 3 rd rear wall portion 58b in the-X direction, is curved along the arc a1 and smoothly connects with the end of the 3 rd side wall portion 58f in the + Y direction.

The 2 nd end e2, which is the end of the 3 rd rear wall portion 58b in the + X direction, is curved along the arc a2 and smoothly connects with the end of the 5 th side wall portion 58k in the + Y direction.

The end portion of the 5 th side wall portion 58k in the-Y direction is curved along the arc a3, and smoothly connects with the end portion of the 4 th side wall portion 58m in the + Y direction.

A plurality of guide portions 58q for guiding movement of an operating member 59 in a depth direction, which will be described later, are formed on the surface of the upper surface portion 58a in the-Z direction.

Each of the plurality of guide portions 58q is formed of a pair of wall bodies that protrude at a height lower than the 1 st side wall portion 58dLb and the 2 nd side wall portion 58dRb in the-Z direction and extend in the depth direction so as to form a groove in the lateral width direction.

In the example shown in fig. 7, the guide portions 58q1, 58q2, 58q3, and 58q4 are provided as a plurality of guide portions 58q in a region spanning the narrow width portion 67d and the wide width portion 67c in the center portion in the lateral width direction in the upper surface portion 58 a. The guide portions 58q1, 58q2, 58q3, and 58q4 are arranged at intervals in the + X direction.

The guide portions 58q1, 58q2 and the guide portions 58q3, 58q4 are disposed at positions line-symmetrical with respect to a central axis Od bisecting the narrow width portion 67d in the lateral width direction in plan view.

Between the ends of the guide portions 58q1, 58q2 in the + Y direction and between the ends of the guide portions 58q3, 58q4 in the + Y direction, locking portions 58p for locking biasing members 77, which will be described later, project in the-Z direction.

Guide portions 58t for guiding movement of the locking portion 70 in the lateral width direction, which will be described later, are provided between the end of the guide portion 58q1 in the-Y direction and the 1 st side wall portion 58dLb, and between the end of the guide portion 58q4 in the-Y direction and the 2 nd side wall portion 58dRb, respectively. In the 1 st side wall portion 58dLb, a guide hole portion 58u through which the locking portion 70 advances and retreats penetrates in the + X direction at a position facing the center of the guide portion 58t when viewed from the + X direction.

A guide hole portion 58u through which the locking portion 70 advances and retreats penetrates the 2 nd side wall portion 58dRb in the-X direction at a position facing the center of the guide portion 58t when viewed from the-X direction.

In the upper surface portion 58a, a plurality of screw fixing portions 58r having screw fixing holes formed at the centers thereof project in the-Z direction.

In the example shown in fig. 7, 1 screw fixing portion 58r and a total of 3 screw fixing portions 58r are provided on the central axis Od between the ends of the guide portions 58q2 and 58q3 in the + Y direction and between each guide portion 58t and the front wall portion 58 cb.

The screw fixing portions 58r disposed in the vicinity of the guide portions 58t are located outside the guide portions 58q1 and 58q4 as viewed in the-Y direction, and have a line-symmetric positional relationship with respect to the center axis Od.

The buffer material fixing plate 58v protrudes in the-Z direction on the upper surface portion 58a in the + Y direction of the screw-fixing portion 58r between the guide portions 58q2, 58q 3.

The buffer material fixing plate 58v has an insertion groove 58v1 into which a buffer material 78 described later is inserted in the + Z direction.

Next, the detailed structure of the upper wall portion 67b will be described.

As shown in fig. 5, the upper wall portion 67b includes a front wall portion 58c, a1 st side wall portion 58dL, a2 nd side wall portion 58dR, a1 st rear wall portion 58eL, and a2 nd rear wall portion 58 eR.

The front wall portion 58c, the 1 st side wall portion 58dL, the 2 nd side wall portion 58dR, the 1 st rear wall portion 58eL, and the 2 nd rear wall portion 58eR are walls extending from the front wall portion 58cb of the base portion 67a, the 1 st side wall portion 58dLb, the 2 nd side wall portion 58dRb, the 4 th wall portion 58eLb, and the 5 th wall portion 58eRb in the + Z direction to the same height in the same shape.

Fig. 8 is a side view of F8 of fig. 6.

As shown in fig. 8, the 1 st side wall portions 58dL and 58dLb have locking projections 58F and guide projections 58CL projecting in the-X direction.

The locking projection 58F is a projection that can be locked to the surface of the rail portion 64 in the + Y direction from the-Y direction. The locking projection 58F is disposed between the 1 st and 4 th rear wall portions 58eL and 58eLb and the guide hole portion 58 u.

The guide projection 58CL is disposed at a position facing the locking projection 58F with the guide hole 58u therebetween. The distance between the locking projection 58F and the guide projection 58CL in the depth direction is set to a size that can move in the vertical direction along the rail portion 64 with both ends of the rail portion 64 formed on the side surface S2 of the rib 61D in the depth direction being sandwiched.

The guide projection 58CL extends in the vertical direction over the entire 1 st side wall portion 58dL, 58 dLb. The depth direction of the guide projection 58CL is the width of the groove g1 (see fig. 3) inserted into the rib 61D so as to be movable in the vertical direction as a whole.

A plurality of screw fixing portions 58r and a plurality of projection portions 58s are provided on the-Y direction surface of the locking projection 58F and the + Y direction surface of the guide projection 58CL, respectively, so as to reduce the contact area with the rail portion 64.

At the end in the + Z direction of the guide projection 58CL, a flat plate portion 58EL extending parallel to the XY plane is formed at a position higher than the upper end of the 1 st side wall portion 58 dL.

At the end of the guide projection 58CL in the-Z direction, a locking projection 58DL is extended by a length h1 from the lower end of the 1 st side wall portion 58dLb in the-Z direction.

The length h1 is set to a size enough to allow the user's hand to be inserted below the base portion 67a when the door container 56A is moved in the vertical direction.

The lateral width direction and depth direction of the locking projection 58DL are such that they can be accommodated inside the recessed groove g 1.

The distance h2 from the lower end of the locking projection 58DL to the upper surface of the flat plate portion 58EL is smaller than the size of the gap G1 in the vertical direction. The lift table main body 58 can pass through the gap G1 of the rib 61D.

A recessed groove 58j for positioning the container body 57 described later in the depth direction is formed at the upper end of the 1 st side wall portion 58 dL. The shape of the groove 58j viewed from the + X direction is, for example, a U-shape opened in the + Z direction.

The position of the recessed groove 58j as viewed from the + X direction is not particularly limited, but in the example shown in fig. 8, it is between the 1 st rear wall portion 58eL and the guide projection 58 CL.

Fig. 9 is a side view of F9 in fig. 6.

As shown in fig. 9, the 2 nd side wall portions 58dR and 58dRb have the same locking projections 58F, recessed grooves 58j, and guide hole portions 58u as the 1 st side wall portions 58dL and 58dLb, except that the 2 nd side wall portions 58dR and 58dRb are formed in positions and shapes that are plane-symmetrical with respect to a plane of symmetry parallel to the YZ plane.

The 2 nd side wall portions 58dR and 58dRb include a guide projection 58CR, a flat plate portion 58ER, and a locking projection 58dR instead of the guide projection 58CL, the flat plate portion 58EL, and the locking projection 58dL in the 1 st side wall portions 58dL and 58 dLb.

The guide projection 58CR, the flat plate portion 58ER, and the locking projection 58DR are the same as the guide projection 58CL, the flat plate portion 58EL, and the locking projection 58DL except for the point of projecting in the + X direction from the 2 nd side wall portions 58DR and 58dRb, and the width in the depth direction and the height in the + X direction are the size of being inserted into the recessed groove g1 (see fig. 3) of the rib 61C so as to be movable in the vertical direction as a whole.

In the present embodiment, since the groove section of a part of the recessed groove g1 of the rib 61C is narrowed by the convex portion p, the guide projection 58CR has a sectional shape that can move up and down without contacting the convex portion p. Specifically, as shown in fig. 5, the guide projection 58CR and the flat plate portion 58ER have a trapezoidal shape with chamfered corners at the end portions in the-Y direction in plan view, and have a smaller width in the depth direction than the guide projection 58CL and the flat plate portion 58 EL.

The planar shape of locking projection 58DR is the same as the planar shape of guide projection 58CR and flat plate portion 58 ER.

As shown in fig. 9, the length of the locking projection 58DR is h1 which is the same as the length of the locking projection 58 DL. The distance from the lower end of latching projection 58DR to the upper surface of flat plate portion 58ER is h2 equal to the distance from the lower end of latching projection 58DL to the upper surface of flat plate portion 58 EL.

As shown in fig. 6, the lower cover 60 covers the elevating table main body 58 from below in a state where the operating member 59 is housed inside the elevating table main body 58.

The lower cover 60 includes a bottom plate 60a and side plates 60bL, 60bR, and 60c extending from the outer edge of the bottom plate 60a in the + Z direction.

The bottom plate portion 60a is a flat plate having substantially the same outer shape as the upper surface portion 58a of the lift table main body 58. However, a rectangular cutout 60e is formed in the bottom plate portion 60a at an end in the + Y direction in a plan view.

In the bottom plate portion 60a, screw holes 60d through which screws 76 are inserted penetrate at positions facing the respective screw fixing portions 58r (see fig. 7) in the elevating table main body 58 in a plan view.

The side plates 60bL and 60bR are walls projecting in the + Z direction from slightly inside the outer peripheral edge of the bottom plate 60a, and are provided at both ends in the lateral width direction of the bottom plate 60a with the notch 60e interposed therebetween. The side plates 60bL, 60bR protruding from the bottom plate 60a have a protruding height equal to or less than the protruding height of the 3 rd rear wall 58b protruding from the upper surface 58 a.

Fig. 10 is a sectional view taken along line F12-F12 in fig. 4.

As shown in fig. 10, the side plate portion 60bL is formed along the inner sides of the 3 rd rear wall portion 58b, the 3 rd side wall portion 58f, the 4 th wall portion 58eLb, and the 1 st side wall portion 58dLb of the lifter main body 58 between the end portion of the cutout portion 60e in the-X direction and the guide portion 58t in the-X direction.

The side plate portion 60bR is formed along the inside of the 3 rd rear wall portion 58b, the 5 th side wall portion 58k, the 4 th side wall portion 58m, and the 2 nd side wall portion 58dRb of the lifter main body 58 between the end portion of the notch portion 60e in the + X direction and the guide portion 58t in the + X direction.

The side plate portion 60c is a wall protruding in the + Z direction from a slightly inner side of the outer peripheral edge of the bottom plate portion 60a in the-Y direction with respect to each guide portion 58 t. The side plate portion 60c is formed along the inner sides of the 1 st side wall portion 58dLb, the front wall portion 58cb, and the 2 nd side wall portion 58dRb of the lifter main body 58. The protruding height of the side plate 60c is equal to the protruding height of the side plates 60bL, 60 bR.

The lower cover 60 is fixed to the elevating table main body 58 by a plurality of screws 76 in a state of being fitted into the lower portion of the elevating table main body 58 from below.

Next, the operation member 59 will be explained.

As shown in fig. 6, operation member 59 is movably sandwiched between box portion 58A and lower cover 60 in the depth direction.

Fig. 11 and 12 are perspective views showing an operation member according to embodiment 1. Fig. 13 is a sectional view taken along line F13-F13 in fig. 10.

As shown in fig. 11, operation member 59 includes operation portion 59A and operation portion 59X.

Operation portion 59A has a rectangular shape in plan view, which is long in the lateral width direction. An operation plate 59A along the ZX plane is provided at an end of the operation portion 59A in the + Y direction. A coupling plate 59c parallel to the operation plate 59A is provided at an end of the operation portion 59A in the-Y direction.

The respective ends of the operation plate 59a and the connecting plate 59c in the-X direction are connected to each other by a side plate portion 59bL extending in the depth direction along the YZ plane. Similarly, the ends in the + X direction are connected to each other by a side plate portion 59bR extending in the depth direction along the YZ plane.

A groove V that opens in the-Z direction is formed between the operation plate 59a and the connecting plate 59c between the side plates 59bL, 59 bR. The groove width of the groove V in the depth direction is a size that can be inserted by a fingertip of a user. The groove width of the groove V in the lateral width direction is a size that allows the user's 2 nd finger to 5 th finger to be inserted with a gap therebetween. Hereinafter, for the sake of simplicity, at least one of the 2 nd to 5 th fingers may be referred to as a non-1 st finger.

The groove V may be formed entirely between the operation plate 59a and the coupling plate 59c, but in the example shown in fig. 11, the groove V is formed in a section from the surface of the operation plate 59a in the-Y direction to an intermediate portion between the operation plate 59a and the coupling plate 59 c. The inner peripheral surface of the groove V in the-Y direction is formed by a flat plate portion 59f parallel to the operating plate 59a, and the end portion of the flat plate portion 59f in the-Z direction and the end portion of the linking plate 59c in the-Z direction are linked by a flat plate portion 59d parallel to the XY plane.

As shown in fig. 12, a flat plate portion 59e parallel to the XY plane is provided at each end in the + Z direction of the operation plate 59a, the side plate portions 59bL, 59bR, and the flat plate portion 59 f.

A plurality of reinforcing ribs extending in the depth direction are provided on the flat plate portion 59d between the flat plate portion 59f and the connecting plate 59 c.

The flat plate portion 59e forms the groove bottom in the + Z direction in the groove V. The depth of the recessed groove V in the vicinity of the operation plate 59a is not particularly limited as long as the non-1 st finger of the user can be locked to the operation plate 59 a. For example, the depth of the groove V may be equal to or greater than the length from the fingertip of the user other than the 1 st finger to the 1 st joint.

As shown in fig. 13, the height in the vertical direction from the flat plate portion 59d to the connecting plate 59c is slightly smaller than the gap from the upper surface portion 58a to the bottom plate portion 60a at the time of assembly of the base portion 67 a.

On the other hand, the end portion of the operation plate 59a in the-Z direction protrudes in the-Z direction beyond the flat plate portion 59 d. Therefore, the side plate portions 59bL, 59bR of the groove V covering the end portions in the lateral width direction have inclined portions inclined from the surface of the flat plate portion 59d in the-Z direction toward the front end of the operation plate 59a in the-Z direction toward the-Z direction as going toward the + Y direction.

The portions of the operation plate 59a and the side plates 59bL, 59bR, which protrude in the-Z direction from the flat plate portion 59d, protrude in the-Z direction from the notch 60e of the lower cover 60.

The operation portion 59A is used for moving the operation member 59 in the depth direction by the user operating the position of the operation plate 59A in the depth direction by putting a finger inserted into the groove V on the operation plate 59A.

The operating member 59 is movable in the depth direction from the 1 st position in the-Y direction indicated by the solid line in fig. 10 to the 2 nd position in the + Y direction at which the operating plate 59a approaches the 3 rd rear wall portion 58b as indicated by the two-dot chain line.

Hereinafter, when the operation member 59 in the assembled state is described, unless otherwise specified, a description will be given of a case where the operation member 59 is disposed at the 1 st position.

The operating portion 59A is disposed at a position facing a portion of the 3 rd rear wall portion 58b parallel to the ZX plane (hereinafter, referred to as a flat plate portion of the 3 rd rear wall portion 58 b) in the depth direction. For example, in the example shown in fig. 10, the operating portion 59A faces the flat plate portion of the 3 rd rear wall portion 58b in the range from the end portion of the flat plate portion of the 3 rd rear wall portion 58b in the + X direction to the vicinity of the end portion in the-X direction.

Therefore, central axis O passing through the center of the width of operation portion 59A in the lateral width direction and extending in the depth direction in plan view_59AIs offset in the-X direction from the center axis Od of the lift main body 58.

The side plate portion 59bR faces the end portion of the flat plate portion of the 3 rd rear wall portion 58b in the + X direction in the depth direction. Thus, the side plate portion 59bR is positioned closer to the-X direction than the 2 nd side wall portion 58dRb in the lateral width direction.

In contrast, the lateral position of the side plate portion 59bL is substantially the same as the lateral position of the 1 st side wall portion 58 dLb.

With this arrangement, the operation plate 59A of the operation portion 59A faces only the flat plate portion of the 3 rd rear wall portion 58b in the depth direction. Therefore, the operation plate 59a can be approached to a position having almost no gap with the inner surface of the 3 rd rear wall portion 58b at the 2 nd position shown by the two-dot chain line.

On the other hand, when the operation plate 59a faces a curved side surface portion of the 3 rd rear wall portion 58b that is curved in the-Y direction as it goes toward the + X direction, such as an arc portion facing the 5 th side wall portion 58k or the 5 th side wall portion 58k, an end portion of the operation plate 59a in the + X direction abuts against an inner peripheral surface of the curved side surface portion. As a result, the moving stroke of the operation member 59 from the 1 st position to the 2 nd position becomes smaller than the example shown in fig. 10.

If the moving stroke of the operation member 59 can be increased, the spring constant of the urging member 77, which will be described later, can be decreased, and thus the operation by the user becomes easier.

The arrangement of operation portion 59A at position 1 is not particularly limited.

In the example shown in fig. 10, the operation plate 59A of the operation portion 59A is positioned to overlap the 5 th side wall portion 58k when viewed from the-X direction.

The connecting plate 59c of the operating portion 59A is positioned to overlap the 4 th side wall portion 58m when viewed from the-X direction. More specifically, the connecting plate 59c is positioned slightly closer to the-Y direction than the connecting portion between the 5 th side wall portion 58k and the 4 th side wall portion 58m as viewed from the-X direction. The connecting plate 59c is also positioned to face the approximate center of the 3 rd side wall portion 58f when viewed from the-X direction.

As shown in fig. 11 and 12, operation unit 59X is a structure other than operation unit 59A in operation member 59. Operating portion 59X extends to a position closer to the-Y direction than operating portion 59A, is formed in a range from flat plate portion 59d to flat plate portion 59e in thickness, and is generally rectangular in shape in plan view as a whole.

As shown in fig. 10, the operating portion 59X has a shape that is plane-symmetrical with respect to a plane S parallel to the YZ plane passing through the central axis Od.

The operating portion 59X includes a transmission member 59B, a reinforcing member 59D, and a driving member 59C.

The transmission members 59B are plate-like members extending in the-Y direction from the connecting plate 59c of the operation portion 59A, and a pair of the transmission members are provided so as to face each other in the lateral width direction. Since each transmission member 59B is plane-symmetric with respect to the plane S, the distance between the transmission member 59B in the-X direction and the 1 st side wall portion 58dLb is equal to the distance between the transmission member 59B in the + X direction and the 2 nd side wall portion 58 dRb.

In contrast, the distance between the transmitting member 59B and the side plate 59bL in the-X direction is greater than the distance between the transmitting member 59B and the side plate 59bR in the + X direction.

As shown in fig. 11, the reinforcing member 59D includes a connecting member 59i and reinforcing ribs 59i1, 59i2, 59i 3.

The connecting member 59i connects the ends of the transmission members 59B in the-Y direction in the lateral width direction.

The shape of the connecting member 59i is not particularly limited as long as rigidity is obtained that can keep the distance in the lateral width direction between the ends of the transmission member 59B in the-Y direction constant. In the examples shown in fig. 11 and 12, the plate is parallel to the XY plane. The connecting member 59i has a rectangular shape in plan view that is long in the lateral width direction.

The shape and number of the reinforcing ribs 59i1, 59i2, 59i3 are not particularly limited as long as the connecting member 59i can be reinforced.

In the example shown in fig. 11, the reinforcing ribs 59i1, 59i2, 59i3 each protrude in the-Z direction from the surface of the connecting member 59i in the-Z direction.

The reinforcing rib 59i1 is a wall extending in the-Z direction from the end edge in the-Y direction of the connecting member 59 i.

The reinforcement ribs 59i2 extend from the + Y direction surface of the reinforcement ribs 59i1 toward the + Y direction. The reinforcing ribs 59i2 are provided in a pair so as to face each other across the center of the connecting member 59i in the lateral width direction.

The reinforcing rib 59i3 is a wall extending in the-Z direction and the + Z direction from the + Y direction end edge of the connecting member 59 i.

Both ends of the reinforcing ribs 59i1, 59i3 in the lateral width direction are connected to the respective transmission members 59B.

The connecting member 59i and the reinforcing ribs 59i1, 59i3 in the reinforcing member 59D fix the distance in the lateral width direction of the end portions of the respective transmission members 59B in the-Y direction.

As shown in fig. 12, in the transmission member 59B in the-X direction, the guide projection 59j1 projects from the coupling member 59i in the + Z direction, and in the transmission member 59B in the + X direction, the guide projection 59j4 projects from the coupling member 59i in the + Z direction. The guide projections 59j1, 59j4 extend along the extending direction of each transmission member 59B.

As shown in fig. 10, the guide projections 59j1, 59j4 are inserted into the guide portions 58q1, 58q4, respectively, and can advance and retreat in the depth direction, which is the extending direction of the guide portions 58q1, 58q 4.

As shown in fig. 12, between the transmission members 59B, lattice portions 59hL and 59hR extending from the connecting plate 59c toward the reinforcing member 59D in the-Y direction are provided in this order in the + X direction. The lattice sections 59hL and 59hR connect the reinforcing member 59D and the operation section 59A in the depth direction.

The lattice portions 59hL and 59hR have shapes plane-symmetrical to each other with respect to the plane S.

In the grid portion 59hL and the connecting member 59i, the guide projection 59j2 parallel to the guide projection 59j1 projects in the + Z direction. In the grid portion 59hR and the connecting member 59i, the guide projection 59j3 parallel to the guide projection 59j1 projects in the + Z direction. The guide projections 59j2, 59j3 extend along the extending direction of each transmission member 59B.

As shown in fig. 10, the guide projections 59j2, 59j3 are inserted into the guide portions 58q2, 58q3, respectively, and can advance and retreat in the depth direction, which is the extending direction of the guide portions 58q2, 58q 3.

As shown in fig. 12, an opening T1L having a rectangular shape in plan view penetrates in the vertical direction between the transmission member 59B and the lattice 59hL in the-X direction. An opening T1R having a rectangular shape in plan view penetrates in the up-down direction between the transmission member 59B and the lattice 59hR in the + X direction.

The reinforcing ribs 59i3 form the inner peripheral surfaces of the openings T1L, T1R in the-Y direction. Bar-shaped projections 59g protruding from the reinforcing ribs 59i3 in the + Y direction are provided on the inner sides of the openings T1L and T1R, respectively.

An opening T2 having a rectangular shape in plan view penetrates between the grid portions 59hR and 59hL in the vertical direction.

As shown in fig. 10, in the vicinity of the inner surfaces in the + Y direction of openings T1R and T1L of operation member 59, locking portions 58p of casing portion 58A are disposed at positions facing rod-like projections 59g in the depth direction.

An end portion of an urging member 77 formed of a compression coil spring in the-Y direction is fitted into an outer peripheral portion of each bar-shaped projection 59 g.

The end of each biasing member 77 in the + Y direction is locked to the locking portion 59p from the + Y direction in a state where each biasing member 77 is compressed.

Thereby, the operation member 59 is urged in the-Y direction by the reinforcing rib 59i 3. Therefore, operation member 59 moves to the 1 st position without applying an external force to operation portion 59A.

The cushioning material fixing plate 58v of the casing portion 58A is disposed in the vicinity of the + Y direction inner surface of the opening T2. The cushioning material 78 is fitted into the insertion groove 58v1 of the cushioning material fixing plate 58 v.

The cushioning material 78 is disposed at a position where it can abut against the connecting plate 59c in a state where the operation portion 59A moving toward the 1 st position does not collide with the projections of the plurality of guide portions 58q, the locking portion 58p, and the like, projecting from the upper surface portion 58 a.

As the cushioning material 78, rubber, an elastic body, or the like having vibration-proof properties is used. Therefore, when operation portion 59A moves to the 1 st position, if it collides with cushioning material 78, the kinetic energy of operation portion 59A is dissipated. This can suppress, for example, impact force, impact sound, and the like from operation unit 59A.

The driving members 59C are provided at the end portions of the respective transmitting members 59B in the-Y direction, respectively.

The driving members 59C move forward and backward in the depth direction together with the transmission members 59B, thereby moving a pair of locking portions 70, which will be described later, in the lateral width direction. The driving members 59C protrude outward from the side surfaces 59k of the transmission members 59B. The interval between the side surfaces 59k in the lateral direction is equal to the interval between the arrangement positions of the driving members 59C. Hereinafter, the interval between the arrangement positions of the driving members 59C in the lateral width direction is referred to as an arrangement distance.

The shape of each driving member 59C as viewed in the-Z direction is not particularly limited as long as the locking portion 70 can be moved in the lateral width direction in accordance with the advance and retreat of the driving member 59C in the depth direction.

In the example shown in fig. 10, the projection shape of each driving member 59C is an isosceles triangle with the apex 59m directed toward the guide portion 58t when viewed from the-Z direction. A convex arc-shaped curved surface is formed at the apex m of each driving member 59C. However, each driving member 59C may be, for example, a scalene triangle in which each base angle on the side surface 59k is an acute angle, or may be a semicircular shape.

At the 1 st position of the operation member 59, each apex portion 59m is opposed to the center of the guide portion 58t in the lateral width direction.

With this configuration, the reinforcing member 59D is disposed between the pair of driving members 59C when viewed in the lateral width direction, and fixes the distance between the pair of driving members 59C in the lateral width direction.

The operation member 59 may be formed of an assembly in which at least one of the operation portion 59A, the transmission member 59B, the driving member 59C, and the reinforcing member 59D is separable, or the operation portion 59A, the transmission member 59B, the driving member 59C, and the reinforcing member 59D may be integrally formed.

The material of the operation member 59 may be metal, resin, or a material other than metal and resin. The operating member 59 may be formed of a composite of a plurality of kinds of materials.

More preferably, the operation member 59 includes a resin molded product in which the operation portion 59A, the transmission member 59B, the driving member 59C, and the reinforcing member 59D are integrally molded.

Operation portion 59X of operation member 59 is located at a center line O extending in the depth direction through a midpoint bisecting the arrangement distance in the lateral width direction in a plan view_59CThe lines are symmetrically arranged. The shape of the operating portion 59X includes the center axis O_59CIs plane-symmetrical with a plane parallel to the YZ plane.

Further, the central axis O_59CSince the operating portion 59X coincides with the central axis Od, it is also plane-symmetric with respect to a plane S passing through the center of the narrow portion 67d of the base portion 67 a.

Since the operating portion 59X receives external forces that are plane-symmetric with respect to the plane S from the biasing member 77 and the locking portion 70 described later when the operating member 59 moves, the external forces can be resisted with good balance.

Since the operating portion 59X is disposed at the center of the laterally narrow portion 67d, the narrow portion 67d of the base portion 67a has less dead space not used for movement of the operating portion 59X than the case of being eccentric with respect to the plane S. Therefore, the space in the narrow portion 67d can be effectively used. The width of the operating portion 59X occupied by the width in the lateral direction of the narrow portion 67d can be relatively increased. This can improve the rigidity of the operating portion 59X.

In contrast, operation unit 59A is disposed asymmetrically with respect to plane S. Operation portion 59A protrudes in the-X direction from the side surface of operation portion 59X in the-X direction. Therefore, the central axis O of the operation portion 59A in the lateral width direction_59A(central axis 1) to the central axis O_59C(center axis 2) is eccentric in the-X direction. I.e. the central axis O_59ACompared with the central axis O_59CToward the axis of rotation O of the refrigerator compartment door 12_LIs eccentric.

By moving the operation portion 59A closer to the rotation axis O in this manner_LThe one side of the operation member 59A is disposed eccentrically, and the width in the lateral width direction (in the example shown in fig. 10, the distance between the side plate portions 59bL and 59bR, hereinafter referred to as the operable width) of the operation portion 59A to which the operation force can be applied is wider than the disposition distance of the drive member 59C.

By thus decentering the operating portion 59A in the-X direction within the range of the length of the flat plate portion of the 3 rd rear wall portion 58b, the operable width can be increased within the range of the length of the flat plate portion of the 3 rd rear wall portion 58 b. In this case, the movement stroke in the depth direction of operation unit 59A can be acquired to a large extent.

If the operable width becomes large, the width selected by the user when hooking the finger at the time of operation becomes wide, and therefore the operability improves.

Next, the locking unit 70 will be explained. The locking portions 70 are disposed on both lateral side portions of the base portion 67a, respectively, and move forward and backward in the lateral direction.

As shown in fig. 10, the shape and the arrangement position of each locking portion 70 are symmetrical with respect to the plane S. Hereinafter, an example of the locking portion 70 arranged in the-X direction will be described.

Fig. 14 is a sectional view taken along line F14-F14 in fig. 10.

As shown in fig. 14, the locking part 70 includes a1 st holder 71, a locking member 73, an urging member 74, and a2 nd holder 75.

The 1 st holder 71 holds the locking member 73 to be movable forward and backward in the-X direction. An opening through which an end of the locking member 73 in the-X direction can be inserted is formed in a front end plate 71a provided in the-X direction of the 1 st holder 71.

A biasing member 72 for biasing the 1 st retainer 71 in the + X direction is disposed between the front end plate 71a and the 1 st side wall portion 58 dLb. For example, a compression coil spring may be used as the biasing member 72.

The locking member 73 has a body 73a extending in the-X direction, and a flat plate portion 73c provided at an end of the body 73a in the + X direction and protruding outward from the body 73 a.

An inclined surface 73b inclined in the + X direction from a lower surface 73f parallel to the horizontal plane toward the + Z direction is formed at the front end of the main body 73a in the-X direction.

The flat plate portion 73c has a function of preventing the front end plate 71a from coming off the opening. An end of a biasing member 74 for biasing the locking member 73 in the-X direction is locked to an end surface of the flat plate portion 73c in the + X direction. For example, a compression coil spring may be used as the biasing member 74.

The locking member 73 is inserted into the guide hole portion 58u so that an end portion of the locking member 73 in the-X direction can advance and retreat.

The 2 nd holder 75 is fixed to the end of the 1 st holder 71 in the + X direction, and constitutes the end of the locking portion 70 in the + X direction.

As shown in fig. 10, a mountain-shaped protrusion 75a protruding in the + X direction when viewed from the-Z direction is formed at the end of the 2 nd retainer 75 in the + X direction. The mountain shape of the protrusion 75a is an isosceles triangle with the apex 75b rounded to a convex arc. However, the shape of the protrusion 75a is not limited thereto. For example, the projection 75a may have various shapes similar to the planar shape of the driving member 59C.

As shown in fig. 14, the end of the 2 nd holder 75 in the-X direction is connected to the end of the 1 st holder 71 in the + X direction. The biasing member 74 is telescopically accommodated in the 1 st holder 71 and the 2 nd holder 75.

The operation of the locking unit 70 will be described.

Fig. 15 is an explanatory view of the operation of the locking part of embodiment 1. Fig. 16 is an explanatory view of the operation of the door container according to embodiment 1.

In the 1 st position of the operating member 59 shown in fig. 14, the top portion 75b of the 2 nd holder 75 abuts against the top portion 59m of the driving member 59C. At this time, the biasing member 72 is compressed between the front end plate 71a and the 1 st side wall portion 58 dLb.

The locking member 73 is urged by the urging member 74 to enter in the-X direction and project outward from the guide hole portion 58 u.

In this state, when the front end of the locking member 73 in the-X direction is pressed in the + X direction by a force greater than the urging force of the urging member 74, the locking member 73 moves in the + X direction. For example, as shown in fig. 15, the tip of the locking member 73 can move into the retraction guide hole portion 58 u.

When the operation member 59 is moved toward the 2 nd position by the user, as shown in fig. 16, each driving member 59C is moved in the + Y direction. The 1 st holder 71 and the 2 nd holder 75 urged by the urging member 72 move toward the inside of the case portion 58A in conjunction with the movement of the driving member 59C.

When the operating member 59 reaches the 2 nd position, the top 75B of the projection 75a abuts against the side surface 59k of the transmission member 59B. Each locking member 73 moves in the lateral width direction together with the 1 st holder 71 and the 2 nd holder 75, and retracts inside the guide hole 58 u.

When the user releases his or her hand from the operation plate 59a, the operation member 59 is moved in the-Y direction by the biasing force of the biasing member 77, and therefore, the operation member 59 returns to the 1 st position, and the locking member 73 of each locking portion 70 returns to a state protruding from the guide hole portion 58 u.

Next, the container body 57 will be described.

As shown in fig. 4, the vessel body 57 is detachably mounted on the elevating table 67. When mounted, the vessel body 57 is supported from below by the elevating table 67.

As shown in fig. 6, container body 57 has a bottom surface portion 57a, an upper wall portion 57u, and a lower wall portion 57 s.

The bottom surface portion 57a and the upper wall portion 57u are box-shaped as a whole, which are opened upward, and the bottom surface portion 57a surrounded by the upper wall portion 57u accommodates the stored material.

The bottom surface portion 57a is plate-shaped and can be placed on the upper surface portion 58a of the lift table 67. The bottom surface portion 57a has a concave polygonal shape in plan view, which is approximately rectangular and overlaps the upper surface portion 58a of the elevating table 67 from above.

The upper wall portion 57u extends from the upper surface of the bottom surface portion 57a to a certain height.

The upper wall portion 57u has a1 st rear wall portion 57eL, a1 st side wall portion 57dL, a front wall portion 57c, a2 nd side wall portion 57dR, and a2 nd rear wall portion 57eR in the-Y direction.

The 1 st, front, 2 nd, and 2 nd rear wall portions 57eL, 57dL, 57c, 57dR, and 57eR are walls extending in the + Z direction from the top surface of the bottom portion 57a along the inside of the 1 st, front, 2 nd, and 2 nd rear wall portions 58eL, 58dL, 58c, 58dR, and 58eR of the lift main body 58, respectively.

A flange portion 57h extending in the-Y direction is formed at the upper end of the front wall portion 57 c.

A ridge 57i extending in the lateral width direction protrudes from the flange portion 57 h.

Flange portions 57gL, 57gR extending outward in the lateral width direction are formed at the upper ends of the 1 st side wall portion 57dL and the 2 nd side wall portion 57dR, respectively.

A locking projection 57j projecting outward from the 1 st side wall portion 57dL and extending in the-Z direction is provided on the lower side of the middle portion in the depth direction of the flange portion 57 gL. When the locking projection 57j is attached to the elevating table 67, it is locked from above to the recessed groove 58j of the 1 st side wall portion 58dL, thereby positioning the container body 57 in the depth direction.

The protruding height of the locking projection 57j protruding from the 1 st side wall portion 57dL may be a height that does not come into contact with projections protruding from the ribs 61C, 61D such as the rail portion 64 when the door container 56A is attached to the rear surface member 53.

A locking projection 57j is formed on the 2 nd side wall portion 57dR, and the locking projection 57j has a position and a shape symmetrical to a plane parallel to the YZ plane bisecting the 1 st side wall portion 57dL and the 2 nd side wall portion 57 dR.

The vertical distance from the lower surface of the bottom surface portion 57a to the lower surfaces of the flange portions 57gL, 57h, and 57gR is equal to or slightly greater than the height from the upper surface of the upper surface portion 58a of the lift main body 58 to the 1 st rear wall portion 58eL, the 1 st side wall portion 58dL, the front wall portion 58c, the 2 nd side wall portion 58dR, and the 2 nd rear wall portion 58 eR. Thus, as shown in fig. 13, the bottom surface portion 57a is placed on the upper surface portion 58a in a state where the container body 57 is mounted on the elevating table 67.

As in the relation between the upper ends of the flange portion 57h and the front wall portion 58c shown in fig. 13, the flange portions 57gL and 57gR are positioned in contact with or slightly above the upper ends of the 1 st rear wall portion 58eL, the 1 st side wall portion 58dL, the 2 nd side wall portion 58dR, and the 2 nd rear wall portion 58 eR.

As shown in fig. 13, the length from the upper end of the ridge 57i to the lower end of the locking projection 58DR is h4 which is greater than h 2. The length from the upper end of the ridge 57i to the lower end of the locking projection 58DL is also the same.

The upper wall portion 57u has a3 rd side wall portion 57f, a3 rd rear wall portion 57b, a 5 th side wall portion 57k, and a 4 th side wall portion 57m in the + Y direction.

The 3 rd side wall portion 57f, the 3 rd rear wall portion 57b, the 5 th side wall portion 57k, and the 4 th side wall portion 57m are wall portions extending in the + Z direction from the peripheral edge of the bottom surface portion 57a along the outer peripheral surfaces of the 3 rd side wall portion 58f, the 3 rd rear wall portion 58b, the 5 th side wall portion 58k, and the 4 th side wall portion 58m of the lifter main body 58 in a plan view.

The 3 rd side wall portion 57f is connected to an end portion of the 1 st rear wall portion 57eL in the-X direction. The 4 th side wall portion 57m is connected to an end portion of the 2 nd rear wall portion 57eR in the + X direction.

The lower wall portion 57s is formed by the 3 rd side wall portion 57f, the 3 rd rear wall portion 57b, the 5 th side wall portion 57k, and the 4 th side wall portion 57m of the upper wall portion 57u extending in the-Z direction, respectively. Therefore, the 3 rd side wall portion 57f, the 3 rd rear wall portion 57b, the 5 th side wall portion 57k, and the 4 th side wall portion 57m are outer walls having side surfaces and front surfaces extending in the vertical direction formed at the end portions of the container main body 57 in the + Y direction.

The positions in the vertical direction of the lower end of the lower wall portion 57s when placed on the elevating table 67 are the same as the positions of the lower ends of the 3 rd side wall portion 58f, the 3 rd rear wall portion 58b, the 4 th side wall portion 58m, and the 5 th side wall portion 58 k. Therefore, the lower wall portion 57s covers the 3 rd side wall portion 58f, the 3 rd rear wall portion 58b, the 4 th side wall portion 58m, and the 5 th side wall portion 58k from the outside. For example, when the lower wall portion 57s is formed of an opaque material, the 3 rd side wall portion 58f, the 3 rd rear wall portion 58b, the 4 th side wall portion 58m, and the 5 th side wall portion 58k are shielded by the lower wall portion 57 s. This improves the appearance of the inner surface portion of the refrigerating chamber door 12.

In the present embodiment, the door container 56A is separated from the rotation axis O_LFrom the 3 rd rear wall part 57b toward the 3 rd end part in the + X direction and the + Y directionThe 2 nd rear wall portion 57eR has a curved side surface portion formed by the 5 th side wall portion 57k and the 4 th side wall portion 57 m.

More preferably, the side wall portion including the 5 th and 4 th side wall portions 57k and 57m is located away from the rotation axis O_LRelatively far corner portion to approximate the radius of rotation r of the refrigerating compartment door 12_LIs curved. In this case, at the time of rotation of the refrigerating chamber door 12, interference of the container body 57 with the refrigerating chamber door 13 can be prevented, and the volume of the receiving space of the container body 57 can be maximized.

In the example shown in fig. 10, the distance from the rotation axis O_LThe relatively distant corner is formed by the 5 th side wall part 57k, and therefore, the radius of curvature and the radius of rotation r of the 5 th side wall part 57k_LAre approximately equal.

Next, the operation of the door container 56A will be described.

As shown by the solid line in fig. 10, the operation member 59 is located at the 1 st position in a state where the operation force from the user is not applied to the operation member 59. In this case, since the 2 nd holders 75 of the respective locking portions 70 are respectively abutted against the top portions 59m of the driving member 59C, the entire locking portions 70 move outward in the lateral width direction. The locking members 73 project from the guide holes 58u toward the space between the locking projection 58F and the guide projection 58CR and the space between the locking projection 58F and the guide projection 58CL, respectively.

At this time, the reinforcing member 59D is disposed between the driving members 59C with the transmission members 59B interposed therebetween, as viewed in the lateral width direction. Therefore, even if each driving member 59C receives a reaction force from each locking portion 70 toward the inside in the lateral width direction, the deflection of each transmission member 59B in the XY plane can be suppressed as compared with the case where the reinforcing member 59D is not provided. This keeps the arrangement distance of the driving members 59C constant, and stabilizes the position of the top portions 59m abutting against the locking portions 70. As a result, the amount of projection of the locking member 73 from each guide hole 58u is stabilized.

When an external force is applied to the tip of each locking member 73 in a state where the operation member 59 is disposed at the 1 st position and each locking member 73 is pushed inward of the case portion 58A, the biasing member 74 compresses and each locking member 73 retracts inward of the guide hole portion 58 u.

When the external force is released, the locking member 73 protrudes outward of the guide hole 58u due to the elastic restoring force of the biasing member 74.

As shown in fig. 13, the user can move the operation member 59 in the-Y direction by, for example, placing the non-1 st finger fb in the concave groove V of the operation portion 59A and applying an operation force in the + Y direction to the operation plate 59A. For example, the non-1 st finger fb is hooked in the + Y direction while the 3 rd rear wall portion 57b is pressed by the 1 st finger fa. In this case, the 3 rd rear wall portion 57b and the operation plate 59a are gripped by the non-1 st finger fb and the 1 st finger fa, and the operation force is easily applied.

As shown in fig. 10, in the present embodiment, since the operation portion 59A in the case portion 58A extends long in the lateral width direction along the 3 rd rear wall portion 58b, the insertion can be performed with a margin in the longitudinal direction of the concave groove V even in a state where all the non-1 st fingers fb are extended.

Therefore, the user can easily insert the non-1 st finger fb into the groove V even in a state where the groove V is not visible. Further, the user can insert 4 non-1 st fingers fb into the groove V, and therefore, it is easy to apply the operation force more stably in this case.

The user can apply an operation force to an appropriate position in the longitudinal direction of the groove V by, for example, reducing the gap between the non-1 st fingers fb or reducing the number of fingers inserted into the groove V. When the user inserts the non-1 st finger fb into the notch V, the non-1 st finger fb can be moved to a position where the operation is easy in the longitudinal direction of the notch V.

When the operation portion 59A moves in the + Y direction, the entire operation member 59 including the driving members 59C connected to the operation portion 59A via the transmission members 58B and the reinforcing member 59D connecting the driving members 59C moves in the + Y direction. At this time, since the plurality of guide projections 59j1, 59j2, 59j3, 59j4 in the operation member 59 are inserted into the plurality of guide portions 58q, the operation member 59 can move in parallel in the + Y direction along the plurality of guide portions 58 q.

Therefore, even if there is a positional deviation in the longitudinal direction of the operation plate 59a on which the operation force acts, the rotation of the operation member 59 in the XY plane can be suppressed, and therefore the operation member 59 can be smoothly moved in parallel.

As shown in fig. 16, when the operating member 59 moves to the 2 nd position, the entire locking portions 70 biased by the biasing member 72 inward of the guide portions 58t in the lateral width direction move inward of the case portion 58A. Thereby, each locking member 73 is retracted to the guide hole portion 58 u. If the user lets go of the non-1 st finger fb hooked on the operation plate 59a, the operation member 59 returns to the 1 st position, and the locking members 73 protrude to the outside of the guide holes 58 u.

Next, the operation of attaching and detaching the door container 56A to and from the rear surface member 53A and the operation of moving the door container in the vertical direction will be described.

Fig. 17 and 18 are explanatory views of the operation of the door container according to embodiment 1. Since the configuration in the-X direction is illustrated in fig. 17 and 18, the operation of the illustrated components will be described below. However, the same applies to the operation of components that are symmetrically arranged in the + X direction, not shown.

In order to attach the door container 56A to the rear surface member 53A, the user lifts the lift table 67 from which the container main body 57 is detached, pulls the operation plate 59a in the + Y direction, and moves the operation member 59 to the 2 nd position, as shown by the two-dot chain line in fig. 17.

In this state, the user lifts the lift table 67, and inserts the lift table 67 into the gap G1 with the front wall portion 58c facing the rear surface member 53A. The size of the vertical opening of the gap G1 is h 3. h3 is set to be larger than a length h2 from the flat plate portion 58EL in the lateral width direction side surface of the lifting table 67 to the lower end of the locking projection 58DL, and smaller than a length h4 from the upper end of the protrusion 57i in the door container 56A to the lower end of the locking projection 58 DL.

Therefore, the lift table 67 can move in the-Y direction to the vicinity of the inner surface 53a through the gap G1. However, the door container 56A cannot pass through the gap G1 in the-Y direction.

After that, the retaining projection 58DL is inserted into the groove g1 from above.

Since the locking member 73 of the locking portion 70 of the lift table 67 is retracted to the inside of the box portion 58A, the locking member 73 does not interfere with the uneven structure of the rail portion 64.

Therefore, the user can move the elevating platform 67 in the vertical direction along the rail portion 64 while holding the upper surface portion 58a of the elevating platform 67 and the operation plate 59a, for example. At this time, since the fingertips of the non-1 st finger fb can come into contact with the lower surface of the flat plate portion 59e, a force for moving the elevating platform 67 in the vertical direction is easily applied. By inserting all the non-1 st fingers fb into the recessed groove V, the range for supporting the vertically movable platform 67 from below is widened, and therefore, the vertically movable platform 67 is easily and stably supported.

In this way, in the state where the guide projection 58CL and the locking projection 58DL are housed in the recessed groove g1, the guide projection 58CL and the locking projection 58DL are shielded by the rail portion 64 and are hardly visible when viewed from the-Y direction. In particular, the locking projection 58DL projecting downward of the elevating platform 67 is not visible, and the appearance of the inner surface of the refrigerating chamber door 12 is improved.

As shown by the solid line in fig. 17, when the user releases his or her finger from the operation plate 59a at the position where the locking portion 70 faces the 1 st rail portion 64a, the operation member 59 moves to the 1 st position, and the locking members 73 of the locking portion 70 protrude outward from the guide hole portion 58 u. Thereby, the locking member 73 protrudes toward the recess portion sandwiched in the vertical direction by the locking plate 64e in the 1 st rail portion 64 a. When the user releases his or her hand from the elevating table 67, the locking member 73 is locked to the locking plate 64e closest to the elevating table 67 from above by the gravity acting on the elevating table 67.

Thereby, the vertical position of the elevating table 67 is fixed. The fixed position of the elevating table 67 is determined by the positions of the plurality of locking plates 64e to be locked. The vertical fixing position of the elevating table 67 can be changed in multiple stages in units of the arrangement pitch of the plurality of locking plates 64 e.

Thereafter, the container body 57 is placed on the elevating table 67. As shown by the solid line in fig. 17, the user holds the container body 57 and moves it upward of the lift table 67, thereby lowering the container body 57. Since the lateral width of the end portion of the container body 57 in the-Y direction is narrower than the gap between the rail portions 64 in the lateral width direction, the user can insert the container body 57 between the ribs 61 at any position above the elevating table 67.

After the container body 57 is moved to a position where each locking projection 57j can be inserted into each recessed groove 58j of the lifting table 67 from above, the user places the container body 57 on the upper surface portion 58 a. Thereby, the vessel body 57 is mounted on the elevating table 67 (see the two-dot chain line in fig. 17). The container body 57 is fixed in position on the elevating table 67 by inserting the locking projections 57j into the recessed grooves 58j from above.

Thus, the door container 56A is mounted in the vicinity of the inner surface 53A of the rear surface member 53A.

The user can similarly install the door container 56B above the door container 56A.

In the present embodiment, the door containers 56A and 56B attached to the rear surface member 53A are movable in the vertical direction by performing a push-up operation and a lock release operation, which will be described below. In the present embodiment, since the door containers 56A and 56B have the same configuration, an example of moving the door container 56A will be described below.

The push-up operation is an operation in which the user does not operate the operation member 59 and applies a force in the + Z direction to the elevating table 67 to move the elevating table 67 in the + Z direction. For example, the user may push up the door container 56A by putting his hand against the lower surface of the base portion 67 a.

When the inclined surface 73b of the locking member 73 abuts against the inclined rib 64fa during the push-up operation, the locking member 73 is pushed inward by the horizontal component of the reaction from the inclined rib 64 fa.

When the locking member 73 passes over the upper locking plate 64e on the upper side, the locking member 73 protrudes outward from the guide hole portion 58 u. At this time, if the user releases his or her hand and stops the push-up operation, the locking member 73 is locked to the over-passed locking plate 64e from above.

By such a push-up operation, the user can move the door container 56A in the + Z direction, and lock the lift table 67 to the lock plate 64e on the upper side.

The door container 56A can be locked further upward during the push-up operation, but cannot be lowered.

The locking release operation is an operation to forcibly release the locking in the vertical direction by the locking member 73.

In the present operation, the user moves the operation member 59 to the 2 nd position. In this case, since each locking member 73 is retracted inside the guide hole portion 58u, the user can freely move the door container 56A within the movable range.

In the present embodiment, the volume of the storage space of the container body 57 in the + X direction is smaller than the volume in the-X direction than the plane S because the 5 th side wall portion 57k at the end in the + X direction is curved in the plan view. Therefore, the center of gravity of the door container 56A including the stored material tends to be eccentric in the-X direction with respect to the plane S.

In this embodiment, the groove V for the user to hook the hand is eccentric in the-X direction with respect to the plane S. Therefore, the user easily supports the door container 56A at a position close to the center of gravity of the door container 56A, and therefore, the vertical movement at the time of releasing the locking becomes easy.

Further, in the present embodiment, since the recessed groove V is formed long in the lateral width direction along the 3 rd rear wall portion 58b, the user can appropriately move the position of the finger hooked on the operation panel 59a within the range of the recessed groove V. Thus, the hand can be moved to a position where the door container 56A is easily supported by the center of gravity of the door container 56A including the stored items.

When the user releases the operation plate 59a, the locking member 73 protrudes and is locked to the lower locking plate 64e closest thereto. Thereby, the movement position of the door container 56A and the like is fixed.

Here, the movable range of the door containers 56A, 56B will be described.

As shown in fig. 18, the lowermost descending position of the door container 56A is a position at which the lower end of the locking projection 58DL is locked to the descending position restricting portion 53d from above. The same applies to the case where the door container 56B is disposed below the door container 56A.

By providing the lowered position restricting portion 53d, even if the door container 56A drops due to a weak supporting force of the user in the locking release operation, the door container 56A can be prevented from falling downward of the recessed groove g 1.

The door containers 56A and 56B can move in the vertical direction within a range where the 1 st rail portion 64a and the locking member 73 can face each other, and can be fixed in position in the vertical direction.

For example, in the case of the door container 56B shown in fig. 18, the ridge 57i can be raised to a position where it abuts against the lower surface 61g of the rib 61F, as shown by the two-dot chain line. However, the length h4 from the front end of the ridge 57i in the + Z direction to the end face of the locking projection 58DL in the-Z direction is longer than the size h3 of the gap G1. Therefore, if the door container 56B is intended to be moved in the + Y direction, the locking projection 58DL interferes with the upper end portion of the 2 nd rail portion 64B, and therefore, the user cannot pull out the door container 56B in the + Y direction. Therefore, when the door container 56B including the stored object is raised by a strong force, the door container 56B can be prevented from being lifted off the rear surface member 53 and being detached.

For example, in a case where the user cannot support the door container 56B in a state where the door container 56B is moved to a position above the 1 st rail portion 64a, the door container 56B may fall down in a state where the user hooks a finger on the operation panel 59 a.

In this case, door container 56B is lowered until locking projection 58DL abuts flat plate portion 58EL of lower door container 56A. The distance between the bottom plate portion 60a, which is the lower surface of the base portion 67a, and the upper end of the container body 57 of the door container 56A is h1 corresponding to the length of the locking projection 58 DL. If h1 is, for example, a value larger than the thickness of the hand, the hand of the user can be prevented from being pinched between the base portion 67a of the door container 56B and the container main body 57 of the door container 56A.

Locking projection 58DL of door container 56B is provided at a laterally outer side of container body 57 of door container 56A, and abuts flat plate portion 58EL of door container 56A supported from below by guide projection 58 CL. Since the flat plate portion 58EL can be formed to have a width wider than the 1 st side wall portion 57dL in a plan view, the container main body 57 and the elevating platform 67 of the door container 56A can be prevented from being damaged by a drop impact.

In such a movement operation of the door container 56A, the user can perform an operation by hooking a finger on the operation member 59 through the operation portion 59A having a width larger than the width of the operation portion 59X of the operation member 59, and therefore, even when the width of the door container 56A in the width direction is narrow, the operability of the user can be improved.

Although the operation of the refrigerator 1A has been described above with the operation of the door containers 56A and 56B as the center, the door containers 54A and 54B have the same configuration as the door containers 56A and 56B except for the lateral width and the positions of the curved corners in the container body and the lifting/lowering table. Therefore, the door containers 54A and 54B have the same functions as the door containers 56A and 56B.

As described above, according to the refrigerator 1A and the door containers 56A, 56B, 54A, and 54B of the present embodiment, even if the door containers are small in size with a narrow bottom area, the vertical movement and the operation of attaching and detaching the door containers to and from the door can be easily performed.

[ 2 nd embodiment ]

A refrigerator according to embodiment 2 will be described.

As shown in fig. 1, a refrigerator 1B according to the present embodiment includes a door container 156 according to the present embodiment in place of the door containers 56A and 56B according to embodiment 1. The following description focuses on differences from embodiment 1.

Fig. 19 is a perspective view showing a door container of the refrigerator according to embodiment 2.

As shown in fig. 19, the door container 156 of the present embodiment has a structure in which the container body 57 of embodiment 1 is integrated with the elevating table 67.

The door container 156 has a container body 157 and a bottom surface 167.

The container body 157 has a lower portion 157a and an upper portion 157 b.

The lower portion 157a is the same as the case portion 58A except that the 3 rd side wall portion 58f (3 rd side wall portion), the 3 rd rear wall portion 58b (front surface portion), the 5 th side wall portion 58k (curved side wall portion), the front wall portion 58cb, the 1 st side wall portion 58dLb (1 st side wall portion), the 2 nd side wall portion 58dRb (2 nd side wall portion), the 4 th wall portion 58eLb (1 st step portion), the 5 th wall portion 58eRb (2 nd step portion), and the 4 th side wall portion 58m (curved side wall portion) of the case portion 58A according to embodiment 1 are formed at positions of the lower wall portion 57s of the container main body 57, respectively. In fig. 19, only the 3 rd rear wall portion 58b and the 3 rd side wall portion 58f are illustrated in relation to the projection direction.

The upper portion 157b differs from the upper wall portion 57u in that: formed on the upper surface portion 58a of the lower portion 157 a; the 1 st rear wall portion 58eL, the 1 st side wall portion 58dL, the front wall portion 58c, the 2 nd side wall portion 57dR, and the 2 nd rear wall portion 58eR similar to those of the 1 st embodiment are provided instead of the 1 st rear wall portion 57eL, the 1 st side wall portion 57dL, the front wall portion 57c, the 2 nd side wall portion 57dR, and the 2 nd rear wall portion 57 eR.

However, in the 1 st side wall portion 58dL and the 2 nd side wall portion 58dR of the present embodiment, the concave grooves 58j are eliminated. Upper ends of the 1 st, front, and 2 nd side wall portions 58dL, 58c, and 58dR have flange portions 57gL, 57h, and 57gR, which have the same shape and the same position as those of embodiment 1, as those of embodiment 1. The ridge 57i is not formed on the flange portion 57h of the present embodiment.

In the 1 st side wall portions 58dL, 58dLb of the present embodiment, a flat plate portion 58EL, a guide projection 58CL, a locking projection 58dL, and a locking projection 58F are formed, which are the same as those of the 1 st embodiment.

In the 2 nd side wall portions 58dR and 58dRb of the present embodiment, a flat plate portion 58ER, a guide projection 58CR, a locking projection 58dR, and a locking projection 58F are formed, which are the same as those of the 1 st embodiment.

Bottom surface portion 167 is the same as base portion 67a except that it has lower portion 157a of container body 157 instead of box portion 58A. That is, the bottom 167 is covered with the lower cover 60 similar to that of embodiment 1. Between the upper surface portion 58a and the lower cover 60, a pair of locking portions 70, an operation member 59, an urging member 77, and a buffer 78 are arranged, which are not shown, as in embodiment 1.

The door container 156 having such a configuration is detachable from the rear surface member 53A and movable in the vertical direction along the rail portion 64 when attached, as in the door container 56A according to embodiment 1.

However, since the door container 156 does not have the projection 57i, it can be attached and detached through the gap G1.

The door container 156 and the refrigerator 1B including the door container 156 according to the present embodiment have the same functions as the door container 56A and the refrigerator 1A according to embodiment 1.

Therefore, according to the refrigerator 1B and the door container 156 of the present embodiment, even if the door container is a small-sized door container having a narrow bottom area, the vertical movement and the operation of attaching and detaching the door can be easily performed.

In the above embodiments, the example of the revolving door in which the door of the refrigerator is opened is described. However, the door is not limited to the swing door that is opened in half. For example, a single-opening revolving door is also possible.

In the above embodiments, the refrigerator door 13 having a wide lateral width has the same configuration as the refrigerator door 12, and the door containers 54A and 54B capable of moving and locking in multiple stages in the vertical direction are disposed.

The door containers 56A, 56B provided on the side of the refrigerating chamber door 12 having a narrow width are smaller in size than the door containers 54A, 54B provided on the side of the refrigerating chamber door 13 having a wide width, and therefore, the weight of the door containers including the stored materials tends to be lighter. Therefore, the user can easily move the device even with one hand when moving up and down.

In the above embodiments, the reinforcing member 59D has been described as coupling the transmission members 59B to each other, but if the transmission members are coupled to the reinforcing member, the pair of driving members may be provided at both end portions of the reinforcing member.

The locking structure and the locking releasing mechanism of the lifting table or the door container to the inner surface portion described in the above embodiments are examples, and are not limited to the above configuration.

As described above, according to at least one embodiment, a refrigerator includes: a refrigerator main body including a storage chamber; a door that openably and closably closes the storage chamber; and a door container having a bottom surface portion in which a storage space for storing a storage object is formed above, a pair of locking portions arranged on both side portions in a lateral width direction of the bottom surface portion and configured to advance and retreat in the lateral width direction, and an operation member provided on the bottom surface portion and configured to operate positions of the pair of locking portions in the lateral width direction, the operation member being provided on the inner surface portion so as to be movable in a vertical direction and detachable with respect to an inner surface portion of the door, the positions in the vertical direction being fixable at a plurality of positions within a movement range, the operation member including: a pair of driving members that move the pair of locking portions in the lateral width direction by moving the pair of locking portions forward and backward in a depth direction intersecting the vertical direction and the lateral width direction; an operation unit that is formed wider in the lateral width direction than an interval between positions where the pair of driving members are arranged in the lateral width direction and applies an operation force for moving the pair of driving members in the depth direction; a transmission member that couples the operation portion and the pair of driving members in the depth direction, respectively, and transmits the operation force to the pair of driving members; and a reinforcing member disposed between the pair of driving members when viewed in the lateral width direction, and configured to fix a distance in the lateral width direction between the pair of driving members, whereby it is possible to provide a refrigerator capable of easily performing vertical movement and operation of attaching and detaching to and from a door even in a small-sized door container having a narrow bottom area.

Several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the inventions described in the claims and the equivalent scope thereof.
