Description

Door of the cabinet

Embodiments of the invention are related to a door of a cabinet.

Previously, for example, a door that opens or closes an opening of a heat insulating box or the like of a refrigerator is constructed by combining a plurality of members. For example, as shown in Fig. 23 and Figs. 24(a) to 24(c), the door 90 of the conventionally constructed casing includes a door front surface material 91 constituting the front surface of the door, a door back surface material 93 constituting the back surface of the door, and a door. A cover member 92 that is blocked between the front material and the door back material. The door front surface material 91 integrally includes a front surface portion 911 constituting a front surface of the door 90, a side surface portion 912 constituting a side surface of the door 90, and an engaging portion 913 that bends an edge portion of the front surface portion 911 in a thickness direction of the door 90, and The rear side edge portion of the side surface portion 912 is bent toward the rear curved portion 914 in a direction parallel to the front portion 911. The lid member 92 has an engaged portion 921 that engages the engaging portion 913 of the front surface material 91.

The door 90 is assembled, for example, in the following manner. First, as shown in FIG. 24( a ), the lid member 92 is moved in the direction of the arrow A1 , and the engaging portion 913 of the door front surface 91 is inserted into the engaged portion 921 of the lid member 92 . Next, as shown in FIG. 24( b ), the lid member 92 is rotated in the direction of the arrow A2 with the engaged portion 921 and the inserted portion of the engaging portion 913 as fulcrums. Thereby, the cover member 92 is fitted to the door front surface material 91. Then, as shown in FIG. 24(c), the door back surface material 93 is brought into contact with the rear curved portion 914 of the door front surface material 91 via a foam heat insulating material 94 such as foaming urethane. Thereby, the door 90 is assembled.

However, in the conventional configuration, when the lid member 92 is attached, a large rotation operation of the lid member 92 shown in FIG. 24(b) is caused. Therefore, the combination is inferior, and the engagement portion 913 is bent by the rotation operation of the lid member 92 to cause deformation such as unevenness. Further, when the engaging portion 913 is formed with irregularities, a gap is formed between the lid member 92 and the engaging portion 913 due to the unevenness, and the appearance is deteriorated.

As shown in FIGS. 3 and 4, the entire block 20 has a rectangular block shape that is long in the vertical direction and flat in the left-right direction. The restricting member 25 is formed in a shape that is symmetrical with respect to the longitudinal direction of the restricting member 25. Thereby, the restriction members 25 provided at the four corners of the door 20 are shared. The regulating member 25 is, for example, a molded article made of a synthetic resin. The restricting member 25 integrally has a main body portion 251, a receiving groove portion 252, two elastic deformation portions 253, and two claw portions 254. The main body portion 251 is formed in a rectangular container shape in which the blocking member 23 is opened on the side of the blocking surface portion 231. In this case, as shown in FIG. 14 , the width dimension W1 of the main body portion 251 is slightly larger than the width dimension W2 between the first inner wall portion 240 and the peripheral wall portion 233 .

The receiving groove portion 252 protrudes toward the side surface portion 222 side of the outer plate member 22, and opens toward the blocking surface portion 231 side of the blocking member 23. The groove width of the receiving groove portion 252 is slightly larger than the thickness of the both end portions 236 of the peripheral wall portion 233. Therefore, the end portion 236 of the peripheral wall portion 233 can be pushed into the inner side of the receiving groove portion 252 of the restricting member 25. In this case, the end portion 236 functions as an action portion that acts on the receiving groove portion 252 of the regulating member 25. The receiving groove portion 252 functions as a receiving portion that receives a force from the end portion 236 as the acting portion.

Further, as shown in FIG. 11, the bottom portion 255 of the receiving groove portion 252 is formed so as to receive the groove portion 252 as the center portion in the longitudinal direction of the receiving groove portion 252 faces outward. The deeper the slope, the cone shape. In other words, the depth of the receiving groove portion 252 gradually becomes shallower toward the center portion from the outer side in the longitudinal direction of the receiving groove portion 252. In this case, the inclination angle of the taper shape of the bottom portion 255, that is, the slope is set to be substantially equal to the slope of the tapered shape of the end portion 236 of the peripheral wall portion 233.

As shown in FIG. 4, each of the two elastic deformation portions 253 is cut out in a part of the main body portion 251, and is formed into a plate shape having a short width. The elastic deformation portion 253 is configured to be elastically deformable toward the longitudinal direction of the blocking member 23 and in this case in the left-right direction of the door 20.

The two claw portions 254 are configured to be bilaterally symmetrical with respect to the longitudinal direction of the restricting member 25, that is, with respect to the vertical direction of the door 20. One of the claw portions 254 is formed as a gentle inclined surface. The other surface of the claw portion 254 is formed to be a surface perpendicular to the elastic deformation portion 253 and the first inner wall portion 240. In this case, the vertical faces of the two claw portions 254 face each other. The claw portion 254 is configured to be insertable into the hole portion 244 formed in the first inner wall portion 240 of the blocking member 23. Further, the claw portion 254 is configured such that the vertical surface of the claw portion 254 can be locked to the wall portion around the hole portion 244 in a state of being inserted into the hole portion 244.

Next, the assembly sequence of the door 20 will be described.

First, as shown in FIG. 9, the worker places the outer panel member 22 on the flat working surface 100, for example. At this time, the outer surface of the surface portion 221 of the outer plate member 22 is in contact with the work surface 100, and the side surface portion 222 is oriented at right angles to the work surface 100. Next, as shown by an arrow B1 in FIGS. 4 and 9, the operator inserts the blocking member 23 between the opposite side surface portions 222 at the end portion of the side surface portion 222 of the outer plate member 22. That is, the insertion portion 226. At this time, the operator attaches the end portions 236 of the peripheral wall portions 233 at both end portions in the longitudinal direction of the blocking member 23 to the surfaces on the surface portion 221 side of the flange portions 223 on the left and right sides of the outer plate member 22, that is, The inner surface of the door 20 (hereinafter referred to as the inner side surface of the flange portion 223).

Further, the operator presses the end portion 236 of the peripheral wall portion 233 along the inner side surface of the flange portion 223 to press the blocking member 23 into the inside of the door 20 (in the direction of the arrow B1). At this time, the end portion 236 of the blocking member 23 is guided by the inner side surface of the flange portion 223, whereby the blocking member 23 moves substantially in parallel with respect to the surface portion 221. Thereby, the blocking member 23 is inserted into a predetermined position between the side surface portions 222 of the outer plate member 22. In this case, the end portion 236 of the blocking member 23 functions as a guiding portion for guiding the insertion of the blocking member 23 with respect to the outer plate member 22.

Here, in a state where the end portion 236 of the peripheral wall portion 233 comes into contact with the inner side surface of the flange portion 223 and functions as a guide portion, the first curved portion 224 of the outer plate member 22 does not come into contact with the blocking member 23. In other words, in a state where the end portion 236 of the peripheral wall portion 233 of the blocking member 23 is in contact with the inner surface of the flange portion 223 of the outer plate member 22, the first curved portion 224 of the outer plate member 22 is not inserted into the blocking member 23. The portion 238 is inserted. Therefore, when the blocking member 23 is inserted between the side surface portions 222, the blocking member 23 is not caught by the first curved portion 224. Therefore, the operator can smoothly insert the blocking member 23 between the side surface portions 222 without directly observing the insertion state of the blocking member 23.

When the blocking member 23 is pressed into the inside of the door 20 in the longitudinal direction of the side surface portion 222 (in the direction of the arrow B1), the contact portion 237 of the blocking member 23 abuts against the second curved portion 225 of the outer panel member 22. Thereby, the blocking member 23 faces the door 20 Further movement inside is limited. Then, as shown by an arrow B2 in FIG. 5 and FIG. 10, the operator presses the blocking member 23 toward the side of the front surface 221 of the outer panel member 22 which is the working surface 100 side. At this time, the blocking member 23 moves along the second curved portion 225 while bringing the contact portion 237 of the blocking member 23 into contact with the second curved portion 225 of the outer panel member 22. Thereby, the blocking member 23 moves in a direction perpendicular to the surface portion 221, that is, in a direction parallel to the thickness direction of the door 20. In this case, the second curved portion 225 of the outer panel member 22 and the contact portion 237 of the blocking member 23 function as a moving portion in which the blocking member 23 is inserted into the insertion member 226, that is, the outer panel member 22 In the state between the side surface portions 222, the blocking member 23 can be moved in the thickness direction of the door 20.

Further, when the operator presses the blocking member 23 toward the surface portion 221 side, that is, when the blocking member 23 is slidably moved toward the surface portion 221 side, as shown in FIGS. 6 and 11 , the blocking member is at the end of the movement thereof. 23 abuts on the surface portion 221. In this case, as shown in FIG. 11, the first curved portion 224 of the outer plate member 22 is inserted into the inserted portion 238 of the blocking member 23. Further, the surface of the peripheral wall portion 233 of the blocking member 23 on the side of the surface portion 221 abuts against the surface portion 221. Thereby, further movement of the blocking member 23 toward the side of the surface portion 221 is restricted.

Next, the operator inserts the restricting member 25 between the outer plate member 22 and the blocking member 23 as indicated by an arrow B3 in FIGS. 7 and 11 . At this time, as shown in FIG. 14, the end portion 236 of the peripheral wall portion 233 of the blocking member 23 is fitted into the receiving groove portion 252 of the restricting member 25. Further, the operator pushes the restricting member 25 along the inner side surface of the flange portion 223 while pressing the restricting member 25 toward the blocking surface portion 231 side of the blocking member 23. At this time, the restricting member 25 is guided by the inner side surface of the flange portion 223 A predetermined position to the outer plate member 22 and the blocking member 23.

When the restricting member 25 is inserted into a prescribed position between the outer plate member 22 and the blocking member 23, the tapered bottom portion 255 of the receiving member 25 that receives the groove portion 252 and the tapered end portion of the peripheral wall portion 233 of the blocking member 23 The portion 236 functions as a wedge. Thereby, the restricting member 25 pushes away between the end portion 236 of the peripheral wall portion 233 of the blocking member 23 and the flange portion 223 of the outer plate member 22.

That is, the restricting member 25 presses the flange portion 223 by being inserted between the flange portion 223 and the blocking member 23. In this case, the end portion 236 of the peripheral wall portion 233 of the blocking member 23 and the bottom portion 255 of the receiving groove portion 252 of the restricting member 25 are formed in an inclined shape, respectively. Thereby, as the restricting member 25 is pressed in toward the blocking surface portion 231 side, the force by which the restricting member 25 presses the flange portion 223 is increased.

Then, when the flange portion 223 receives the force from the regulating member 25, the entire outer plate member 22 moves in the direction indicated by the arrow B4 in Fig. 12, and the regulating member 25 moves in the direction of the arrow B5. That is, the restricting member 25 and the outer plate member 22 are pulled toward each other, and the outer side surface of the flange portion 223 of the outer plate member 22 moves in a direction in which the inner side surface of the corner wall portion 235 of the blocking member 23 is in close contact with each other. Further, the first curved portion 224 of the outer panel member 22 is further pushed toward the inner side of the inserted portion 238 of the blocking member 23. Thereby, the outer plate member 22 is in close contact with the blocking member 23, and the gap between the outer plate member 22 and the blocking member 23 is densely filled.

Further, by the action of the restricting member 25 as a wedge, the outer side surface of the flange portion 223 of the outer plate member 22 comes into contact with the inner side surface of the corner wall portion 235 of the blocking member 23 in a state where the pressure is received. Similarly, by limiting the member 25 as a wedge The inner side surface of the blocking surface portion 231 of the outer plate member 22 and the surface of the peripheral wall portion 233 of the blocking member 23 on the side of the blocking surface portion 231 are brought into contact with each other under pressure. Thereby, the blocking member 23 is firmly fixed between the side surface portions 222 of the outer plate member 22. In this manner, the restricting member 25 functions as a restricting unit that restricts the movement of the blocking member 23 in a state where the blocking member 23 is located at the end of the movement.

Further, as shown in FIG. 14, the width dimension W1 of the restricting member 25 is slightly larger than the width dimension W2 between the first inner wall portion 240 and the peripheral wall portion 233. Therefore, when the restricting member 25 is inserted between the first inner wall portion 240 and the peripheral wall portion 233, a force is applied in a direction in which the first inner wall portion 240 is separated from the peripheral wall portion 233. In this case, since the first inner wall portion 240 is connected to the second inner wall portion 241 that is provided at a right angle to the first inner wall portion 240, the first inner wall portion 240 is opposed to the peripheral wall portion 233. The deformation is small. The peripheral wall portion 233 transmits the force received from the restricting member 25 to the abutting portion 239 via the connecting portion 243.

In other words, the restricting member 25 is inserted between the abutting portion 239 and the first inner wall portion 240, and the peripheral wall portion 233 is pushed away from the first inner wall portion 240. Further, the restricting member 25 pushes the abutting portion 239 away from the first inner wall portion 240 via the peripheral wall portion 233 and the connecting portion 243, whereby the abutting portion 239 is in close contact with the side surface portion 222 of the outer plate member 22. Inner side. As a result, the blocking member 23 is more firmly fixed between the side portions 222 of the outer plate member 22.

Further, when the restricting member 25 is pressed into the state of FIGS. 8 and 12, the one claw portion 254 of the restricting member 25 is locked to the hole portion 244 of the first inner wall portion 240. Therefore, the direction in which the restricting member 25 is pulled out from the blocking member 23, that is, the direction away The movement of the direction of the blocking member 23 is restricted. Thereby, the restricting member 25 is fixed between the outer plate member 22 and the blocking member 23. Further, the removal of the restriction member 25 is performed in the following manner. The worker presses the elastic deformation portion 253 with a tool or the like to elastically deform the elastic deformation portion 253 in a direction away from the first inner wall portion 240. Thereby, the claw portion 254 is pulled out from the hole portion 244 of the first inner wall portion 240. Then, the restriction of the movement of the restricting member 25 caused by the engagement of the claw portion 254 with the hole portion 244 is released, so that the restricting member 25 can be removed.

After the operator attaches the restricting member 25, as shown in FIG. 13, the inner member 21 is attached to the assembly of the outer plate member 22 and the blocking member 23. At this time, the operator abuts the outer peripheral portion of the inner member 21 against the flange portion 223 of the outer plate member 22 and the rear wall portion 234 of the blocking member 23. Thereby, an assembly of the inner member 21, the outer plate member 22, and the blocking member 23 having a space inside is formed. Further, the operator fills the inside of the assembly of the inner member 21, the outer plate member 22, and the clogging member 23 with, for example, a foaming urethane of the in-situ foaming type as a heat insulating material. Thereby, the door 20 having heat insulation is completed. Further, the heat insulating material of the door 20 may be provided with, for example, a vacuum heat insulating panel instead of the foaming urethane or the vacuum heat insulating panel may be provided together with the foaming urethane. In this case, for example, the vacuum heat insulating panel is disposed inside the outer panel member 22 before the inner member 21 is attached.

Thereby, when the door member 20 is assembled, the operator inserts the blocking member 23 between the two side surface portions 222 without being in contact with the surface portion 221 of the outer panel member 22, and the blocking member 23 is oriented toward the opposite side. The surface portion 221 moves in a direction perpendicular to the direction of the surface portion 221. Therefore, the blocking member 23 can be mounted to the outer panel The member 22 is not accompanied by a large rotation. Therefore, it is possible to suppress the bending of the outer plate member 22 accompanying the rotation operation of the blocking member 23. The worker can easily attach the blocking member 23 to the outer panel member 22, thereby improving workability. Further, by this, it is possible to suppress the occurrence of irregularities in the outer panel member 22. As a result, the gap between the blocking member 23 and the outer panel member 22 is less likely to occur, and the appearance is also excellent.

In the terminal end of the movement of the blocking member 23 in the state of being attached to the outer panel member 22, the first curved portion 224 of the outer panel member 22 is inserted into the inserted portion 238 of the blocking member 23. Thereby, the movement of the blocking member 23 is restricted, so that the blocking member 23 can be prevented from accidentally coming off from the outer panel member 22. Moreover, the gap between the blocking member 23 and the outer plate member 22 is not conspicuous, and the appearance is also improved.

Further, when the operator inserts the blocking member 23 into the insertion portion 226 of the outer panel member 22, the operator can touch the second portion 225 of the outer panel member 22 with the contact portion 237 of the blocking member 23 as a reference. Thereby, the worker does not need to perform work while visually checking the attachment state of the blocking member 23 and the outer plate member 22, and workability is improved.

The door 20 includes a restricting member 25 as a restricting unit that restricts the movement of the blocking member 23 in a state where the blocking member 23 is attached to the outer panel member 22, that is, the blocking member 23 is located at the moving terminal. Thereby, the blocking member 23 can be prevented from being accidentally detached from the outer panel member 22 more effectively.

The restricting member 25 is inserted between the abutting portion 239 of the blocking member 23 and the first inner wall portion 240, and pushes the abutting portion 239 away from the first inner wall portion 240 to close the abutting portion 239 to the outside. The side portion 222 of the plate member 22. With this, blocking The member 23 is firmly fixed between the side surface portions 222 of the outer plate member 22.

The restricting member 25 is guided to a predetermined position between the outer plate member 22 and the blocking member 23 by the inner side surface of the flange portion 223. Thereby, even when the insertion position of the restricting member 25 is hidden inside the blocking member 23 or the outer panel member 22 and is not easily seen by an operator, the operator can easily attach the restricting member 25. As a result, workability is improved.

The blocking member 23 serves as a guiding portion for guiding the insertion of the outer plate member 22, and has an end portion 236 of the peripheral wall portion 233. Thereby, even when the insertion position of the blocking member 23 is hard to be seen by an operator, the worker can easily attach the blocking member 23 to the outer panel member 22. In other words, even if the worker does not drill into the lower side of the working surface 100 and directly visually confirms whether or not the inserted portion 238 of the blocking member 23 enters the first curved portion 224 of the outer panel member 22, the blocking member 23 can be easily attached to the outside. Plate member 22. As a result, workability is improved.

Further, it is possible to prevent scratches or peeling of the appearance surface of the clogging member 23 or the outer plate member 22 caused by the clogging member 23 and the outer panel member 22 being touched at an inappropriate position. In other words, for example, in the conventional configuration shown in FIG. 23, when the engaged portion 921 of the lid member 92 is press-fitted and the engaging portion 913 of the door facing member 91 is inserted into the engaged portion 921, it is difficult to see that it is engaged. The positional relationship between the portion 921 and the engaging portion 913. Therefore, the end portion of the engaging portion 913 touches the lid member 92 and the lid member 92 is scratched. On the other hand, according to the present embodiment, even when the insertion position of the blocking member 23 is not easily seen by the worker, the worker can easily attach the blocking member 23 to the outer panel member 22, thereby reducing the engaging portion. 913 end touch The cover member 92 is scratched by the cover member 92.

Further, in a state where the end portion 236 is in contact with the inner side surface of the flange portion 223, the surface side portion of the blocking member 23 is not in contact with the outer panel member 22. Thereby, when the blocking member 23 is inserted between the side surface portions 222 of the outer panel member 22, the surface side portion of the blocking member 23 does not come into contact with the outer panel member 22 to hinder the insertion thereof. Thereby, the operator can more easily attach the blocking member 23 to the outer panel member 22. As a result, the workability is further improved.

The restricting member 25 is configured to generate a force for pressing the flange portion 223 by being inserted between the flange portion 223 and the blocking member 23. Further, the outer plate member 22 is moved by the flange portion 223 from the regulating member 25 to move in a direction in which it is in close contact with the blocking member 23. Thereby, the blocking member 23 and the outer plate member 22 can be more firmly fixed by the insertion of the restricting member 25. Moreover, the gap between the blocking member 23 and the outer plate member 22 can be reduced, so that the appearance can be further improved.

The restricting member 25 is configured to increase the force of pressing the flange portion 223 as it is inserted into the blocking member 23. Thereby, the operator can easily press the restricting member 25 between the outer plate member 22 and the blocking member 23, whereby the workability is improved.

The blocking member 23 has a corner wall portion 235 as a covering portion covering the flange portion 223. Thereby, the operator can attach the blocking member 23 to the outer panel member 22 so that the flange portion 223 enters the inner side of the corner wall portion 235. Therefore, the operator can determine the position at which the blocking member 23 is inserted into the outer panel member 22 using the corner wall portion 235 as a reference. As a result, the attachment of the blocking member 23 becomes easy, thereby achieving an improvement in workability. Further, the corner wall portion 235 covers the flange portion 223 and a portion of the side surface portion 222 Minute. Therefore, at the corner of the door 20, the gap between the outer panel member 22 and the blocking member 23 is hidden, so that the appearance is improved.

The second engaging portion 412 is located inside the corner wall portion 235 of the blocking member 23 shown in FIG. 18 in a state where the blocking member 23 is attached to the outer panel member 22, in this case, the corner wall portion 235 and the peripheral wall portion 233. between.

As shown in FIG. 17, the third engaging portion 413 is formed in a rectangular hole shape through a part of the first curved portion 224 of the outer plate member 22. The third engaging portion 413 is located outside the peripheral wall portion 233 of the blocking member 23 shown in FIG. 18 in a state where the blocking member 23 is attached to the outer panel member 22. As shown in FIG. 17, the fourth engaging portion 414 is formed in a rectangular hole shape through a part of the second curved portion 225 of the outer plate member 22. The fourth engaging portion 414 is located outside the peripheral wall portion 233 of the blocking member 23 shown in FIG. 18 in a state where the blocking member 23 is attached to the outer panel member 22.

As shown in FIG. 18, each of the engaged portions 421 to 414 is integrally formed with the blocking member 23 at both end portions of the blocking member 23 in the longitudinal direction. Each of the engaged portions 421 to 414 is provided at a position corresponding to each of the engaging portions 411 to 414 of the outer panel member 22 . In this case, the engaged portion 421 is referred to as the first engaged portion 421, and the engaged portion 422 is referred to as the second engaged portion 422, and the engaged portion 422 is referred to as the second engaged portion 422. The engaging portion 423 is referred to as a third engaged The portion 423 and the engaged portion 424 are referred to as a fourth engaged portion 424. In this case, the first engaged portion 421 corresponds to the first engaging portion 411, the second engaged portion 422 corresponds to the second engaging portion 412, and the third engaged portion 423 is engaged with the third engaging portion 423. The fourth engaged portion 424 corresponds to the fourth engaging portion 414.

The first engaged portion 421 is formed in a groove shape in which a part of the blocking member 23 on the side of the blocking surface portion 231 is recessed. In this case, the first engaged portion 421 is provided in the width direction of the blocking member 23, that is, around the end portion on the inner member 21 side in the thickness direction of the door 20. Further, the first engaged portion 421 is located inside the corner wall portion 235 and formed in an elongated groove shape along the corner wall portion 235. When the blocking member 23 is attached to the outer panel member 22, the first engaging portion 411 of the outer panel member 22 shown in Fig. 17 is inserted into the first engaged portion 421 of the blocking member 23 shown in Fig. 18 .

The second engaged portion 422 is provided around the end portion of the blocking member 23 in the longitudinal direction, and is formed to protrude from the blocking surface portion 231 side of the blocking member 23 toward the outer plate member 22 side. The second engaged portion 422 is provided in the vicinity of the center portion in the thickness direction of the door 20 in the width direction of the blocking member 23 or slightly on the side of the inner member 21 with respect to the center portion. In this case, the second engaged portion 422 is formed in a rib shape that connects the corner wall portion 235 of the blocking member 23 and the first inner wall portion 240. Further, the second engaged portion 422 may not be the rib shape, but may be a so-called claw shape in which the corner wall portion 235 and the first inner wall portion 240 are not connected. When the blocking member 23 is attached to the outer panel member 22, the second engaged portion 422 of the blocking member 23 shown in Fig. 18 is inserted into the second engaging portion 412 of the outer panel member 22 shown in Fig. 17 .

The third engaged portion 423 is formed as a blocking face portion 231 of the self-blocking member 23 The so-called claw shape in which the side protrudes toward the side of the outer plate member 22. The third engaged portion 423 is provided in the width direction of the blocking member 23, that is, the periphery of the end portion on the outer plate member 22 side in the thickness direction of the door 20. When the blocking member 23 is attached to the outer panel member 22, the third engaged portion 423 of the blocking member 23 shown in Fig. 18 is inserted into the third engaging portion 413 of the outer panel member 22 shown in Fig. 17 .

The fourth engaged portion 424 is provided in the vicinity of the end portion in the longitudinal direction of the blocking member 23, and is formed in a so-called claw shape that protrudes from the blocking surface portion 231 side of the blocking member 23 toward the outer plate member 22 side. The fourth engaged portion 424 is provided in the width direction of the blocking member 23, that is, in the vicinity of the central portion in the thickness direction of the door 20, or slightly on the outer plate member 22 side with respect to the central portion. In this case, the fourth engaged portion 424 is provided on the outer side of the peripheral wall portion 233 of the blocking member 23, that is, the contact portion 237 of the blocking member 23. When the blocking member 23 is attached to the outer panel member 22, the fourth engaged portion 424 of the blocking member 23 shown in Fig. 18 is inserted into the fourth engaging portion 414 of the outer panel member 22 shown in Fig. 17 .

Next, the assembly procedure of the door 20 of the present embodiment will be described.

The door 20 of the present embodiment is also assembled on the flat work surface 100 in the same manner as the door 20 of the first embodiment. The operator moves the blocking member 23 in a horizontal direction with respect to the working surface 100 as indicated by an arrow C1 in FIGS. 19 and 21 , and is inserted into the insertion portion 226 between the opposing side surface portions 222 of the outer panel member 22 . When the blocking surface portion 231 of the blocking member 23 touches the first engaging portion 441 located at the front end portion of the flange portion 223 of the outer plate member 22, the movement of the blocking member 23 in the direction of the arrow C1 is restricted.

Next, the operator turns the blocking member 23 toward FIGS. 19 and 21 When the arrow C1 is biased, the blocking member 23 is moved toward the working surface 100 side as indicated by an arrow C2 in FIGS. 20 and 22 . Then, as shown in FIG. 20, at the end of the movement, the first curved portion 224 of the outer plate member 22 is inserted into the inserted portion 238 of the blocking member 23. In this case, as shown in FIG. 20, the first engaging portion 411 of the outer plate member 22 is inserted into and engaged with the first engaged portion 421 of the blocking member 23. Further, as shown in FIG. 22, the second engaged portion 422 of the blocking member 23 is inserted into and engaged with the second engaging portion 412 of the outer plate member 22. Further, as shown in FIG. 20, the third engaged portion 423 of the blocking member 23 is inserted into and engaged with the third engaging portion 413 of the outer plate member 22. Further, although the details of the fourth engaged portion 424 of the blocking member 23 are not shown, they are inserted into and engaged with the fourth engaging portion 414 of the outer plate member 22.

As described above, in the case where the blocking member 23 is located at the end of the movement in the moving direction of the outer plate member 22, each of the engaging portions 411 to 414 of the outer plate member 22 and the engaged portion 421 of the blocking member 23 are provided. The engaged portion 424 is engaged. Moreover, by this, the relative movement of the blocking member 23 and the outer plate member 22 is restricted. In this case, the engaging portions 411 to 414 of the outer plate member 22 are engaged with the engaged portions 421 to 424 of the blocking member 23, for example, such as "咔嚓". The sound is accompanied by the vibration of the sound. Thereby, the operator can feel that the blocking member 23 has been mounted at a predetermined position of the outer panel member 22 in accordance with the sound or the tactile sensation.

Then, the operator attaches the inner member 21 to the assembly of the outer plate member 22 and the blocking member 23 in the same manner as in the first embodiment. Next, the operator fills the inside of the assembly of the inner member 21, the outer plate member 22, and the blocking member 23 with, for example, a foaming urethane which is a field foaming type as a heat insulating material. Thereby, it is insulated The door 20 is completed.

Thereby, similarly to the first embodiment, the blocking member 23 can be attached to the outer panel member 22 without a large rotation operation. Therefore, the same operational effects as those of the first embodiment are obtained. Further, by this, the door 20 does not include the restricting member 25 as a restricting unit which is formed separately from the outer plate member 22 and the blocking member 23. That is, in the present embodiment, the restriction means for restricting the relative movement of the outer plate member 22 and the blocking member 23 is integrally formed with the outer plate member 22 and the blocking member 23. Therefore, compared with the first embodiment, the number of parts can be reduced in accordance with the amount of the regulating member 25. As a result, cost can be reduced or weight can be reduced. Moreover, the man-hours of the mounting restriction member 25 can be reduced, and thus the work efficiency is further improved.

Here, for example, in the first embodiment, when the worker forgets to attach the restriction member 25, the relative movement of the outer plate member 22 and the blocking member 23 is not restricted. In this state, when the foamed urethane is filled into the interior of the door 20 and expanded, the outer panel member 22 is likely to bulge due to the expansion force, which affects the appearance quality. On the other hand, in the second embodiment, since the blocking member 23 is attached to the outer panel member 22 without using the restricting member 25, the relative movement of the blocking member 23 and the outer panel member 22 is necessarily restricted. Therefore, it is possible to prevent a human error caused by forgetting to attach the restriction member 25, and as a result, further improvement in the quality of the door 20 can be achieved.
