BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a box-shaped structure such as a storage, and more particularly to a structure such as an intersection of a partition body and a main body provided in an opening of the box-shaped structure.

[0002]

2. Description of the Related Art An insulated storage such as a refrigerator is shown in FIG.
It is configured as shown in 0. In the figure, the main body 3 of the storage 1 has an opening on the front side, which is a vertical partition 5a, 5b.
And the horizontal partition bodies 7a and 7b partition into a plurality of small openings. FIG. 30 is, of course, a conceptual diagram, and the number of partitions is
Actually, as shown in the drawing, there are various portions, but there are intersections between the inner surface of the main body 3 and the partition bodies 5b, 7a, 7b, and the partition bodies 5a, 5b.
Corners 9 are formed at the intersections of b, 7a, 7b, and the gaps formed in the corners 9 are filled with caulking 9a to be hidden as shown in FIG.

[0003]

As described above, in the conventional technique of filling the gap formed at the intersection of the box-shaped structure with caulking, caulking varies depending on the operator, and the appearance of caulking varies or there is a gap in the caulking portion. In addition, there is a problem in that the caulking is peeled off when the box-shaped structure is transported or the door is opened and closed. In addition, at the time of work, the caulking material was attached to another portion other than the target of caulking, and the worker's hands and a part of the body were stained, so that the area around the caulking was not so beautiful. Therefore, the present invention does not require time-consuming work such as caulking work and work that tends to result in variations in completion, and is easy to install, and stable quality and a clean appearance can be obtained.
Further, it is another object of the present invention to provide an intersection connection structure of a box-shaped structure having a corner cover that does not easily come off.

[0004]

With the above-mentioned objects in mind, the structure for connecting a crossing portion of a box-shaped structure of the present invention is constructed as follows. That is, a corner cover attached to the corners of the inner surface that defines the main body opening of the box-shaped structure and the partition that is connected to intersect the inner surface and divides the opening into a plurality of small openings. A plate body having an L-shaped cross section in which a main body side cover plate extending along the inner surface and a partition body side cover plate extending along the surface of the partition body are integrally formed; And, a protrusion is formed on one of the inner surface or the partition body, and a recess for receiving the protrusion is formed on the other side to form an occlusal connection structure between the corner cover and the inner surface or the partition body.
Although the protrusions and the recesses are formed as described above, in one embodiment, the protrusions are formed on the inner surface of the main body and one or both side edges of the partition body, and the protrusions and the one of the two cover plates of the corner cover are formed. The side edge is formed with a line recess for receiving the line protrusion. When the protrusions are formed on both side edges of the inner surface of the main body and the partition body, the end portions are formed on the side edges that are adjacent to each other. Further, in another embodiment, a connecting frame forming a surface of the inner surface of the main body is formed by forming facing recesses on both side edges of one or two cover plates forming the plate-shaped body of the corner cover. Both end edges and / or both end edges of the cover body of the partition body are fitted into the groove recesses as projections. In still another embodiment, one and / or two cover plates forming an L-shaped cross-section plate-shaped body of the corner cover are provided with a recess on one side edge,
The projections with barbs are formed respectively on the back surface of the box-shaped structure, and both side edges of the connection frame forming the inner surface of the main body of the box-like structure and / or the cover forming the surface of the partition body are received in the groove recesses, and the connection is made. A hole for receiving the barbed protrusion is formed in the frame or the cover body. The corner cover configured as described above has a single structure that is independent at each corner of the intersection between the inner surface of the main body to be attached and the partition, but it is installed at two corners sandwiched by one partition. The corner covers to be worn may be connected together to form an integral structure.

[0005]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, the opening on the front surface of the main body 11 of the refrigerator 10, which is a box-shaped structure, is the partition 1
It is divided into four small openings 17 by 3, 15 and 15, and these small openings 17 are opened and closed by a door 19. The figure shows a state in which the door 19 is opened. As shown in FIG. 2, the main body 11 is configured by connecting an exterior 21 and an interior 23 by a connection frame 25, and further filling the inside thereof with an integrally foamed heat insulating material 27. On the other hand, as shown in FIG. 6, the partition body 15 includes a front plate 31 having a U-shaped cross section.
And the cover body 33 are fitted to each other, and the foam insulation material 35 is filled between them. In the figure, reference numeral 37 is a dew condensation preventing heater.

Referring to FIG. 1, two types of corner covers 40 and 50, which will be described later, are shown, but these are shown at the same time to facilitate understanding of the attached state. It does not mean that a plurality of types of corner covers are simultaneously used in the refrigerator 10. First, a corner cover 40 having a shape as shown in FIG. 3 is attached to a corner of an intersection of the main body 11 and the partition body 15 as shown in FIGS. 1 and 2 as described later. In FIG. 3, the corner cover 4
At 0, the flat plate-shaped cover plates 41 and 43 intersect vertically to form an integral plate-shaped body having an L-shaped cross section. Cover plates 41, 43
Although not clearly shown in the drawing, the tip portions 41a and 43a of the cover are slightly curved and protrude toward the back surface side facing the main body 11 or the partition body 15, and therefore, the cover plate 4 is attached at the time of attachment.
1, 43 respectively spread along the surface of the connection frame 25, which is the inner surface of the main body 11, and the surface of the cover body 33 of the partition body 15, and are pressed exactly against each surface at the tip portions 41a, 43a.

Further, a bent portion 41b is formed on the back surface side of one side edge of the cover plate 41 of the corner cover 40, and a series of groove recesses 45 are defined. The line recess 45 receives a line protrusion 25a formed on the side edge of the connection frame 25 as shown in FIG. The occlusal state between the line projection 25a and the line recess 45 is enlarged and more clearly shown in FIG. 4, which is a sectional view taken along the line AA of FIG. However,
In FIG. 4, the connection frame 25 is shown by a two-dot chain line which is an imaginary line. As is clear from the figure, the groove 45 is not a mere recess, but a fixing projection 46 is formed on the inlet side so as to occlude with certainty.
In 5a, the cross section of the tip is large in a substantially circular shape and the cross section of the root is small. As shown in FIGS. 7 and 8, such a combination of the line projections and the line depressions forms line projections 45 ′, 45 ″ on the side edges of the cover plates 41 ′, 41 ″.
May be formed, and the side edges of the connection frames 25 'and 25 "may be formed with ridges to engage them.

Further, the corner cover 50 attached to the corner of the intersection of the partitions 13 and 15 has a shape as shown in FIG. As can be seen from FIG. 5, the corner cover 50 has the same basic structure as the above-mentioned corner cover 40 in the basic structure in which two orthogonal cover plates 51 and 53 form a plate-shaped body having an L-shaped cross section. There is a side edge 53b of the cover plate 53
It differs from that in that the groove 55 is formed in the. Then, as shown in FIG. 6, the groove 5 of the corner cover 50
The reference numeral 5 receives and fits the line projections 33a formed at the corners of the cover body 33 of the partition body 15, and engages them. Regarding the cross-sectional shapes of the line recess 55 and the line protrusion 33a, refer to the corner cover 4
The above explanation for 0 is still valid. In the corner covers 40 and 50, the two cover plates 41, 43, 51,
Although the groove recesses 45 and 55 are formed only on one side of 53, FIG.
As shown in FIG. 2, the two cover plates 61, 63 of the corner cover 60 are
It goes without saying that the grooved portions 65a and 65b may be formed on the respective one side edges of the above. As a matter of course, in this case, a total of two strip projections are formed on the same side edge of the main body and the partition body. Therefore, since there are two occlusal places, the corner cover 60 can be attached more firmly.

Next, another embodiment of the present invention will be described with reference to FIGS.
1 and FIG. In the figure, exterior 1

Partition body side cover plate 8 of the corner cover 80 used
A groove 85 for receiving the protrusion 108a is formed on the rear surface side of the side edge portion of No. 3, and a protruding piece 83a is formed on the rear surface side of the opposite side edge portion, which is the same as the protruding piece 71a. The tip is rounded inward to wrap the outer edge of the cover body 108. In this way, the corner cover 80 is securely fixed. FIG. 15 shows a C view of the corner cover 80. The corner cover 70 of FIG. 10 and the corner cover 80 of FIG. 14 are formed by forming the line recesses 75 and 85 on only one of the main body side cover plate and the partition body side cover plate, respectively. A line recess may be formed on the back surface side of the side edge portion, and a line protrusion may be formed on both the connection frame of the main body and the cover body of the partition body. In this case, the shape of the corner cover 90 when viewed from the inner side of the opening of the main body is as shown in FIG. 16, and the planar shape and the side surface shape are the same as those in FIGS. 10 and 14, respectively. In FIG. 16, reference numerals 91 and 93 are a main body side cover plate and a partition body side cover plate, respectively.

Still another embodiment will be described with reference to FIGS. 17 to 23. First, referring to FIGS. 17, 18 and 19, the corner cover 14 in this embodiment will be described.
No. 0 has cover plates 141 and 143 similar to the above-mentioned corner cover, but further the main body side cover plate 1 facing the inner surface of the refrigerator main body.
On the back surface of 41, a claw 147, which is a projection with a barb, is formed to project. The exterior 151 and the interior 153 of the main body are connected by a connection frame 155. The exterior 151 and the connection frame 155 have square holes 151a and 155b as locking holes into which the claws 147 are inserted, as shown in FIG. Has been drilled. As shown in FIG. 17, the claw 147 has a barb 147a, and when it is inserted, it is elastically deformed by being guided by the inclined surface of the barb 147a. The shape and dimensions are determined such that the inner surface of 151a and the root surface of the claw 147 are in good contact with each other (Fig. 1).
9). On the other hand, similarly to the above, a strip protrusion 155a is also formed on the inner edge of the connection frame 155, and a bent portion 141a is formed on the back surface side of the inner edge of the main body side cover plate 141, and the strip defined by this is formed. It is received and fitted in the recess 145. The partition side cover plate 143 does not have the above-mentioned protrusions and fittings, but the corner cover 140 has the groove 145 and the claw 1.
The connection frame 155 of the main body by the main body side cover plate 141 having 47
It engages in two places and is firmly attached.

In the corner cover 140, a claw 147 as a barbed protrusion is formed on the main body side cover plate 141 facing the connection frame 155 of the refrigerator main body.
As shown in FIG. 7, a claw 167 is formed on the partition body side cover plate 163 facing the cover body 179 of the partition body, and the front plate 17 of the partition body is formed.
7 and the square holes 177a and 179b of the cover body 179 may be inserted and locked by the barb 167a. In this case, the ribs 175a and 179a are formed on the inner edge of the connection frame 175 and the inner edge of the cover body 179, respectively, and are formed on the bent portion 161a of the cover plate 161 and the bent portion 163a of the cover plate 163, respectively. Streak 165 and 1
66 respectively received and engaged. FIG. 23 shows a side view of the corner cover 160 viewed from the back side of the opening.

In the above-mentioned corner covers 140 and 160,
Although the claws 147 and 167 are formed on only one of the two cover plates of the plate-like body, the corner cover may be formed by forming the claws on both of the two cover plates. Of course, in this case, the connection frame and the exterior of the refrigerator main body, the front plate of the partition body and the cover body are respectively provided with square holes, and the claws are inserted into the square holes. However, the plan sectional view and the vertical sectional view are shown in FIG.
7 and FIG. 21, the illustration is omitted. Also,
The side view seen from the back side of the opening is the same as that of FIG.

The corner covers 40, 50, 60, 70, 80, 90, 140, described with reference to FIGS.
160 has a shape and structure that is attached separately at each corner formed at the intersection of the inner surface of the refrigerator main body and the partition, but it covers two corners facing each other with the partition interposed therebetween. It may be configured as an integrated type corner cover adapted to be attached. The structure will be described below, but since the basic structure of the portion covering one corner is the same as that of the above-described single-unit type corner cover, only typical ones will be described and redundant description will be omitted. Avoid it. Refrigerator 200 shown in FIG.
Is almost the same as the above-mentioned refrigerator 10, and is only slightly different in the structure of the mounting portion of the later-described integrated corner cover. The front opening of the main body 201 is divided into four small openings 209 by partition bodies 203, 205, 207 intersecting the inner surface thereof. Inner surface of main body 201 and partition 2
03, 205, 207 intersections and partitions 203, 2
Coupling type corner covers 220, 230, 240, which will be described later, are attached to the intersections of 05, 207. Although three types of united type corner covers are shown, they are not shown to be used at the same time, they are shown for convenience of explanation for convenience of understanding, and they are usually used in a unified manner.

25 and 26, the inner surface of the main body and the partition body 20 are shown.
5A and 5B show the shape and mounting state of the united-type corner cover 220 attached to the intersection with 5, 207. As can be easily guessed by comparing FIG. 25 and FIG. 5, the united corner cover 220 has a structure in which two corner covers 50 are symmetrically arranged and joined by a connecting plate 225. Therefore, the cover plates 221, 223 and the cover plates 222, 2 which are orthogonal to each other
The structure formed by 24 is the same as that of the corner cover 50, and the description thereof can be applied to the integrated corner cover 220. The cover plate 223, 224 is formed with a line recess 227 on one side edge, respectively, and as shown in FIG. 26, receives a line protrusion 213a formed on the outside of the corner of the cover body 213 of the partition body 205 and engages with it. ing. Ridge 21
The cross-sectional shapes of 3a and the groove 227 can be appropriately selected from those shown in FIGS. 4, 7, and 8, or can be other modified shapes.

FIG. 27 shows the structure of a united type corner cover 230 attached to the intersection of the inner surface of the main body and the partition body 203. 27 and FIG. 3 are compared with each other, the cover plates 231, 233 and the cover plate 23 that intersect with each other for easy estimation.
The structure formed by 2, 234 is basically the same as that of the corner cover 40, and the combined-type corner cover 230 has a structure in which these are symmetrically arranged and combined by a connecting plate 235. The line recesses 237 formed on one side edge of the cover plates 231 and 232 are also formed on one side edge of the connecting plate 235 to form one line protrusion, which is a line protrusion formed on one side edge of the connection frame of the main body. Is occluded. The occlusal state and the attached state are the same as those in FIG. 2, so the illustration thereof is omitted.

The structure in which the two types of united corner covers 220 and 230 described above are combined is indicated by reference numeral 240 in FIG. This combined-type corner cover 240 is formed by arranging two corner covers 60 shown in FIG. 9 symmetrically, and connecting and combining them by a connecting plate 245. It can be easily understood by contrasting with. A similar line recess 247 is formed on one side edge of the cover plates 243 and 244.
The line recesses 249 formed on one side edge of the first and second 242 are continuous as one line. In FIG. 24, the united corner cover 240 is shown attached to the intersections of the partitions 203, 205, 207, but it is needless to say that it can be attached to other intersections. As described above, the united type corner covers 220, 230, 240 have a symmetrical shape in which the unitary type corner covers 40, 50, 60 are symmetrically arranged and united, but the uniting method is not limited to this. Not something. However, in actual production, it is common to make the shape symmetrical as described above in consideration of manufacturability, cost and the like.

It is obvious to those skilled in the art that the united corner covers 70, 80, 90, 140, and 160 can be symmetrically arranged to form the united type corner cover according to the above-described united and integrated procedure. Let's do it. In addition, it is obvious that appropriate modification may be made in consideration of manufacturability, attachment property, etc. in the case of the combination, and therefore the combination type corner cover thus formed should be included in the concept of the present invention. It is a thing. FIG. 29 shows a united shape of the corner cover 160 as an example thereof. In FIG. 29, reverse puncturing claws 259 similar to the claws 167 are formed integrally on the back surface of the cover plates 253, 254 facing the partition body of the united type corner cover 250 so as to be integrally formed. It is inserted and locked in the square holes of the front plate and cover body. These square holes and claws 2
The relative dimensional relationship of 59 is similar to that of the corner cover 160. A line recess 257 is formed at one side edge of the cover plates 253 and 254 (located on the inner side of the opening). The cover plates 253 and 254 and the cover plate 25 intersecting with the cover plates 253 and 254.
The angle α formed by 1 and 252 is an obtuse angle slightly larger than a right angle. Further, when the angle θ formed by the cover plates 253 and 254 and the connecting plate 255 is an acute angle slightly smaller than a right angle, it is suitable for firm attachment and fixing.

[0019]

As described above, according to the present invention,
A protrusion is formed on one of the inner surface of the main body and the partitioning body that forms the corner cover and the corner where this corner cover is attached, and the partition body is formed on the other side, and a recess for receiving the protrusion and fitting is formed, and the fitting of both is fixed. Since the corner cover is attached by being held by the projection for use, the corner cover can be attached very easily and the gap formed at the corner of the intersection can be stably and aesthetically covered.
