Abstract

PROBLEM TO BE SOLVED: To assure mounting and holding of inner members such as container supporting members to a reinforcing plate for a long time in a drawer-type door of a refrigerator. SOLUTION: A reinforcing plate 46 is provided with a protrusion 56 which is inserted in a reinforcing plate mounting hole 51 of a door inner plate 43 and has its front surface portion positioned approximately on the same plane as that of the opposite outside plate side of the door inner plate 43. An inner member mounting hole 57 is formed in this protrusion 56. With a screw 49 inserted in the inner member mounting hole 57, a container supporting member (an inner member) 48 is mounted on the reinforcing plate 46. Due to such a construction, the inner member mounting hole 57 directly comes into contact with the container supporting member 48 with no gap so that even when the screw 49 is tightly fastened, the peripheral portion around the inner member mounting plate 57 is blocked by the container supporting member 48 thus causing no plastic deformation. Accordingly, a sufficient amount of repulsive force relative to the fastening of the screw 49 is generated at a portion of the inner member mounting hole 57 so that the engagement of the female thread of the inner member mounting hole 57 with the screw 49 is strengthened thus preventing loosening of the screw 49.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door having an internal member attached to a reinforcing plate attached to a door inner plate.

[0002]

2. Description of the Related Art Conventionally, for example, a drawer type door of a refrigerator is provided with a structure shown in FIG.
In FIG. 11, 1 is a door outer plate, 2 is a door inner plate, and 3, 4
Denotes upper and lower caps, 5 denotes two reinforcing plates, 6 denotes a gasket, 7 denotes a container supporting member, and 8 denotes a screw. Among the above-mentioned components, the door outer plate 1 is made of a metal plate that is strong against external force, while the door inner plate 2 is made of lightweight plastic, and the reinforcing plate 5 is made of a metal plate similar to the door outer plate 1. It consists of

As shown in FIGS. 12 to 14, the door inner plate 2 is provided with the support member mounting portion 9 from the door outer plate 1 side (left side in FIG. 13) to the door outer plate 1 side (FIG. 13). The support member mounting portion 9 is formed with, for example, three screw insertion holes 10 and one reinforcing plate positioning protrusion 11 is formed on the door outer plate 1 side. It is formed to protrude. Also, the support member mounting portion 9
The door outer plate 1 has reinforcing plate guide walls 12 on its upper, lower, left and right sides.
Are formed, and a claw 1 is provided at each of the left and right ends of the guide wall 12.
3 is formed.

On the other hand, support member mounting holes 15 are formed in the reinforcing plate 5 at positions corresponding to the screw insertion holes 10 of the door inner plate 2 in the main body 14 having a rectangular shape at the center. A positioning hole 16 is formed at a position corresponding to the reinforcing plate positioning projection 11. In this case, the support member mounting holes 15 are formed by burring around each of them around the door outer plate 1 with the formation of the cylindrical portion 15a.
Are formed as flat holes. Further, L-shaped and inverted L-shaped anchor portions 17 and 18 are formed on the upper and lower portions of the main portion 14, respectively, and side walls 19 are formed on both left and right sides as shown in FIG. .

In this configuration, at the time of assembling, first, the reinforcing plate 5 is positioned in the guide wall 12 beyond the claw 13 of the guide wall 12 of the door inner plate 2, and the positioning hole 16 is formed in the positioning projection 11.
And the edge of the side wall 19 is engaged with the claw 13 so that the reinforcing plate 5 is attached to the surface of the support member mounting portion 9 on the door outer plate 1 side.
(See FIGS. 13 and 14). Thereafter, a sealing tape 20 is attached to a surface of the main body 14 of the reinforcing plate 5 on the door outer plate 1 side to seal the support member mounting hole 15 and the positioning hole 16.

Then, the door inner plate 2 is assembled to the door outer plate 1, and the upper and lower caps 3, 4 are attached to the door outer plate 1 and the door inner plate 2.
A heat insulating material (not shown) such as polyurethane is injected in the form of a stock solution, and foamed and filled therein.

After the curing of the heat insulating material is completed, the gasket 6 is attached to the door inner plate 2. As shown in FIG. 15, the mounting portion 21 of the container support member 7 is applied to the support member mounting portion 9 of the door inner plate 2, and the screw insertion hole 10 of the door inner plate 2 and the reinforcing plate Mounting holes 22 formed in advance corresponding to the supporting member mounting holes 15
0, 15 and then screw (tapping screw) 8
Are screwed into the support member mounting holes 15 from the mounting holes 22 through the screw insertion holes 10, respectively, and tightened tightly to mount the container supporting member 7 to the reinforcing plate 5 with the door inner plate 2 interposed therebetween.

A storage container (not shown) is attached to the container supporting member 7, and in this state, the container supporting member 7 is attached to a rail member inside the refrigerator cabinet (not shown) so as to be slidable back and forth.

[0009]

In the case of the above, the support member mounting hole 15 of the reinforcing plate 5 is screwed into the screw insertion hole 1 of the door inner plate 2.
It is in a relationship of communicating with the mounting hole 22 of the container support member 7 with 0 interposed therebetween. Therefore, when the screw 8 screwed into the support member mounting hole 15 from the mounting hole 22 through the screw insertion hole 10 is strongly tightened, as shown in FIG. 16, the periphery of the support member mounting hole 15 of the reinforcing plate 5 is pulled. Then, while crushing the peripheral portion of the screw insertion hole 10 of the door inner plate 2, the peripheral portion of the support member mounting hole 15 of the reinforcing plate 5 is plastically deformed so as to enter the inside of the screw insertion hole 10.

As described above, the support member mounting hole 15 of the reinforcing plate 5 is provided.
When the peripheral portion is plastically deformed, a sufficient repulsive force of the support member mounting hole 15 portion of the reinforcing plate 5 against the tightening of the screw 8 cannot be obtained, and the engagement between the threaded portion of the support member mounting hole 15 and the screw 8 becomes weak. , The screw 8 is likely to be loosened. As a result, the door is lowered or tilted from the screw 8 tightened portion, and the opening and closing of other doors below the door are hindered. When the door is tilted, the gasket 6 does not evenly contact the refrigerator cabinet, which may cause a cold air leak.

On the other hand, the sealing tape 20 attached to the surface of the main body 14 of the reinforcing plate 5 on the door outer plate 1 side is a tip of the peripheral cylindrical portion 15a of the support member mounting hole 15 and the reinforcing plate of the door inner plate 2. Since it comes into contact with the tip of the positioning projection 11 and receives the foam filling pressure of the heat insulating material in this state, the portion of the support member mounting hole 15 in contact with the tip of the peripheral cylindrical portion 15a and the reinforcing plate of the door inner plate 2 The portion in contact with the tip of the positioning projection 11 is easily broken, and the heat insulating material may leak from the broken portion.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a long and reliable attachment and holding of an internal member such as a container support member to a reinforcing plate without causing a drop or inclination. Another object of the present invention is to provide a door, in which a seal tape attached to a surface of a reinforcing plate on a door outer plate side is not broken, and a leak of a heat insulating material can be more reliably prevented.

[0013]

In order to achieve the above object, a door according to the present invention comprises at least a door outer plate and a door inner plate, and a surface of the door inner plate on the door outer plate side. A reinforcing plate to be attached, and an internal member attached to the reinforcing plate with a door inner plate interposed therebetween. First, a reinforcing plate assembling hole is formed in the door inner plate, and the reinforcing plate is formed in the reinforcing plate. Is formed in the reinforcing plate assembling hole to form a convex portion whose front end surface portion is substantially flush with the surface of the door inner plate on the side opposite to the door outer plate, and forms an internal member mounting hole in this convex portion. The internal member is attached to the reinforcing plate by a fastening member inserted into the internal member attachment hole.

According to this, the internal member mounting hole of the reinforcing plate is in direct contact with the internal member without any gap. For this reason, even if the fastening member inserted into the internal member mounting hole is strongly tightened,
The periphery of the internal member mounting hole of the reinforcing plate is stopped by the internal member and does not plastically deform. As a result, a sufficient repulsive force of the internal member mounting hole portion of the reinforcing plate with respect to the tightening of the tightening member is obtained, and the engagement between the threaded portion of the internal member mounting hole and the tightening member is strengthened, and the tightening member is loosened. Disappears.

In the door of the present invention, secondly, the inner member mounting hole is formed by burring whose tip end does not protrude from the surface of the reinforcing plate on the door outer plate side, and the reinforcing plate is formed on the surface of the reinforcing plate on the door outer plate side. It is characterized in that a heat insulating material is filled by foaming between a door outer plate and a door inner plate by sticking a sealing tape. According to this, there is no protrusion on the door outer plate side surface of the reinforcing plate to which the seal tape is attached, and the breakage of the seal tape by the protrusion is prevented.

The length L is set to be smaller than the height H of the projection 56 plus the thickness t of the reinforcing plate 46. That is, the inner member mounting hole 57 is formed such that the distal end does not protrude from the surface of the reinforcing plate 45 on the door outer plate 42 side.

On the other hand, the reinforcing plate assembling holes 51 and 52 of the door inner plate 43 are larger than the convex portions 56 (the reinforcing plate assembling holes 5).
2 is a flat hole which is sufficiently larger than the convex portion 56). In addition, these reinforcing plate assembling holes 51 and 52 are evident from FIG. As described above, the reinforcing plate 46 is formed in a tapered shape on the side opposite to the door outer plate 42 (left side in the drawing) in accordance with the shape of the convex portion 56 of the reinforcing plate 46. FIG. 1 shows the door outer plate 4 of the main portion 55 of the reinforcing plate 46.
Also shown is a seal tape 58 which is attached to the two surfaces and seals the entire inner member mounting hole 57.

Further, as shown in FIGS. 4 and 5, L-shaped and inverted L-shaped anchor portions 59 and 60 are formed on the upper and lower portions of the main portion 55 of the reinforcing plate 46, respectively. A side wall 61 is formed in the portion as shown in FIG.

With this configuration, at the time of assembling, first, the reinforcing plate 46 is positioned in the guide wall 53 beyond the claw 54 of the guide wall 53 of the door inner plate 43, and the convex portion 56 is moved from the door outer plate 42 side into the door. While being inserted into the reinforcing plate assembly holes 51 and 52 of the plate 43,
The edge of the side wall 61 is engaged with the claw 54. This allows
The reinforcing plate 46 is positioned on the surface of the inner member mounting portion 50 of the door inner plate 43 on the door outer plate 42 side, and the height H of the convex portion 56 is substantially equal to the plate thickness T of the door inner plate 43.に よ り Because of the same setting, the front end surface portion is positioned substantially flush with the surface of the door inner plate 43 on the side opposite to the door outer plate 42 (see FIG. 1).

Thereafter, a sealing tape 58 is attached to the surface of the main body 55 of the reinforcing plate 46 on the door outer plate 42 side to seal all the internal member mounting holes 57. And then, the door inner plate 4
3 is assembled to the door outer plate 42, and the door outer plate 42 and the door inner plate 4
The upper and lower caps 44 and 45 are attached to 3, and a heat insulating material (not shown) such as polyurethane is injected into the inside thereof in the form of a stock solution, foamed, and filled. As a result, the reinforcing plate 46
Anchor portions 59 and 60 are buried in a heat insulating material and are used for fixing the reinforcing plate 46.

After the hardening of the heat insulating material is completed, a gasket 47 is attached to the door inner plate 43. Note that the door inner plate 43 is provided with a gasket mounting groove (not shown) around the surface on the side opposite to the door outer plate 42.
have. Next, the mounting portion 62 of the container support member 48
Is applied to the internal member mounting portion 50 of the door inner plate 43, and the mounting portion 50 is formed in advance in correspondence with the reinforcing plate mounting hole 51 of the door inner plate 43 and the internal member mounting hole 57 of the reinforcing plate 46. The holes 63 are aligned with the holes 51 and 57, and three screws (tapping screws) 49 are screwed from the mounting holes 63 into the internal member mounting holes 57, respectively, and strongly tightened, and the container supporting member 48 is inserted into the door. The plate 43 is attached to the reinforcing plate 46 with the plate 43 interposed therebetween.

After that, a storage container (not shown) is attached to the container support member 48, and in this state, the container support member 48 is attached to the rail member inside the refrigerator cabinet 31 so as to be slidable back and forth. .

Now, in the case of the configuration as described above,
The inner member mounting hole 57 of the reinforcing plate 46 is formed such that the front end portion of the convex portion 56 is located substantially flush with the surface of the door inner plate 43 on the side opposite to the door outer plate 42, so that the container support member 48 as an internal member is formed. Directly in contact with no gap. For this reason, the internal member mounting hole 57
Even if the screw 49, which is a fastening member inserted through the hole, is strongly tightened, the peripheral portion of the internal member mounting hole 57 of the reinforcing plate 46 is kept in the container supporting member 4
8 and the support member mounting hole 15 of the conventional reinforcing plate 5
There is no plastic deformation as in the peripheral portion. Therefore, the internal member mounting hole 57 of the reinforcing plate 46 for tightening the screw 49 is provided.
The repulsive force of the portion is sufficiently obtained, and the engagement between the threaded portion of the internal member mounting hole 57 and the screw 49 is strengthened, so that the screw 49 is not loosened. .

As a result, the door 40 does not relatively fall or tilt from the screw 49 tightened portion,
Obstruction of opening and closing other doors below can be avoided. or,
Since the door 40 is not tilted, the gasket 47 comes into uniform contact with the refrigerator cabinet 31, thereby preventing cold air leakage.

The front end surface of the convex portion 56 of the reinforcing plate 46 may be located substantially flush with the surface of the door inner plate 43 on the side opposite to the door outer plate 42, for example, 0.1 [mm]. If it is a small size, it may be retracted from the surface of the door inner plate 43 on the side opposite to the door outer plate 42 or may be protruded. Member 4
8 can be securely pressed against and fixed to the door inner plate 43, which is preferable in terms of the mounting strength of the container support member 48.

The convex portion 56 of the reinforcing plate 46 is
Is located in the correct position and in the correct position inside the door 40, the reinforcing plate assembling holes 51, 5 are formed on the surface of the door inner plate 43 on the side opposite to the door outer plate 42.
It looks exposed from 2. On the other hand, if the reinforcing plate 46 is displaced from the correct position inside the door 40 due to the filling pressure of the heat insulating material or the like and is inclined from the correct posture, the protrusion 5
Reference numeral 6 denotes a surface of the door inner plate 43 on the side opposite to the door outer plate 42 and a reinforcing plate assembly hole 5.
It does not appear exposed from 1,52.

As described above, the protrusions 56 of the reinforcing plate 46 are formed on the surface of the door inner plate 43 on the side opposite to the door outer plate 42 on the reinforcing plate assembling holes 51, 52.
It is possible to determine the position and posture of the reinforcing plate 46 inside the door 40 based on whether or not the reinforcing plate 46 is exposed from the outside. It is also possible to prevent a problem that a defective product is generated due to mounting.

In addition, in the case of the above configuration, the reinforcing plate 4
Since the inner member mounting hole 57 of No. 6 is formed by burring whose tip end does not protrude from the surface of the reinforcing plate 46 on the door outer plate 42 side, the surface of the reinforcing plate 46 on which the sealing tape 58 is affixed on the door outer plate 42 side. Has no protrusions, and can prevent the seal tape 58 from being torn by the protrusions, thereby preventing leakage of the heat insulating material.

7 to 9 show a second embodiment of the present invention, and only the parts different from the first embodiment will be described. In this embodiment, the door outer plate 72 of the specification switching room door 71 is replaced with the left and right side walls 72a instead of the door 40.
In addition, the upper and lower side walls 72b and 72c corresponding to the upper and lower caps 44 and 45 are integrally formed in a rectangular box shape, and ribs 73 are respectively formed on the upper and lower inner edges of the opened rear surface. Has formed. Both ends 73 a of the rib 73 are bent inward in the thickness direction of the door outer plate 72. On the other hand, the door inner plate 74 has side walls 74a formed on both left and right side edge portions toward the door outer plate 72 side.
Claws 75 are formed at the upper and lower ends of a, respectively.

With this configuration, at the time of assembly, the door inner plate 74 is advanced from the back side of the door outer plate 72, and as shown in FIG.
4 a is inserted into the inside of the left and right side walls 72 a of the door outer plate 72 and is brought into contact therewith, and the claws 75 are engaged with the tips of both ends 73 a of the rib 73. At the same time, the upper and lower edges of the door inner plate 74 are brought into contact with the ribs 73 as shown in FIGS. Then, a heat insulating material (not shown) such as polyurethane is injected between the door outer plate 72 and the door outer plate 73 in the state of a stock solution, foamed, and filled.

By doing so, the door 71 can be assembled with a reduced number of parts used, and the cost can be reduced. In addition, due to the small number of parts, joints of parts where there is concern about leakage of the heat insulating material can be reduced, and leakage of the heat insulating material can be reduced. Further, the door outer plate 7
Both ends 73a of the second rib 73 are bent inward (in the thickness direction of the door outer plate 72), and the left and right side walls 74a of the door inner plate 74 are in contact with this. Thereby, the distance can be increased in a narrow gap outward from the engagement portion by the claw 75, and leakage of the heat insulating material can be more reliably prevented.

A handle 76 is formed on the upper surface of the door outer plate 72 as shown in FIG. Further, both side walls 72a are formed in a curved shape bulging outward from both left and right side edges of the door inner plate 74. This is in anticipation of the fact that when the door inner plate 74 shrinks after molding, the left and right side walls 74a are easily deformed in a curved shape indenting inward. This is also to more surely contact the side wall 74a with the inner surfaces of the side walls 72a. For this reason, a curved shape that swells outward after contraction is left to some extent from both left and right side edges of the door inner plate 74. Further, FIG. 9 shows a gasket mounting groove 77 formed on the periphery of the surface of the door inner plate 74 on the side opposite to the door outer plate 72 (not shown in FIGS. 7 and 8).

FIG. 10 shows the left and right side walls 7 of the door inner plate 74.
A side wall 74b instead of 4a is shown. This door inner plate 7
The left and right side walls 74b of 4 are formed so as to expand toward the front.
Thereby, the contact of the side wall 74a with the inner surfaces of the left and right side walls 72a of the door outer plate 72 can be more surely prevented, and the leakage of the heat insulating material can be more reliably prevented. The change in the dimensional relationship can be coped with by following the two side walls 74b so as to change the expansion and contraction, so that the leakage of the heat insulating material can be prevented more reliably.

In addition, the whole door is not limited to the refrigerator door, but can be widely applied as a door in general. Therefore, the internal member is not limited to the container supporting member 48, but the container itself or another container. It may be. or,
The ribs 73 of the door outer plate 72 and the side walls 74a of the door inner plate 74 in the second embodiment are the door outer plate 72 and the door inner plate 7 respectively.
4 may be provided on the left and right instead of the upper and lower sides. Further, the reinforcing plate 46 is not divided into two. The two parts may be constituted by one sheet.

[0041]

The present invention is as described above.
The following effects are obtained. According to the door of the first aspect, even if the fastening member is strongly tightened, the peripheral portion of the internal member mounting hole of the reinforcing plate is not plastically deformed. This can be done for a long time, without falling or tilting the door. Also, depending on whether or not the protrusion (inner member mounting hole portion) of the reinforcing plate is exposed from the reinforcing plate mounting hole on the surface of the door inner plate on the side opposite to the door outer plate, the reinforcing plate inside the door is determined. Since the position and the posture can be determined, it is possible to prevent a problem that the internal member is attached to the reinforcing plate having the incorrect position and the posture to cause a defective product.

According to the door of the second aspect, it is possible to prevent the seal tape from being broken by the projection, and to prevent the heat insulating material from leaking.
