Description

[Technical field]

[0001] The present invention relates to an easily assembled waterproof case that can be used for a variety of purposes, including transporting, storing, and housing items. [Background technology]

[0002] In general, various cases (boxes) are used in various industries. For example, in the transportation industry, boxes for storing and transporting luggage are mounted on the backs of trucks and motorcycles, installed on dollies for transporting luggage, and further mounted on dollies towed by bicycles (see, for example, Patent Documents 1 and 2). Meanwhile, in detached houses and the like, so-called delivery boxes are used for receiving luggage (see, for example, Patent Document 3). Furthermore, in various facilities, rack-type cases are used to install communication devices and inspection equipment (see, for example, Patent Document 4).

[0003] These cases are made of various materials in a box shape and of a certain size depending on the purpose of use. For example, hard cases used outdoors are made sturdy enough to protect the luggage and to prevent the outside diameter from deforming even when external force is applied, and waterproofing is required, so gaps in each part of the case are sealed with a waterproofing filler.

[0012] As shown in Figure 1, the easily assembled waterproof case C (hereinafter simply referred to as this case C) is a case that comprises a case body B that is configured in an overall box shape and a door D that is provided on any one side of the case body B and that opens and closes this side, and is used for transporting, storing, and housing items, as well as for a variety of other purposes.

[0013] The case body B comprises eight main body corner frames 1 forming each corner of the box shape, at least twelve main body constituent frames 2 which are connected between each of the main body corner frames 1 via water-stopping materials 4A and which form a box-shaped frame together with each of the main body corner frames 1, and five panels 3 which form the five sides of the box shape, with any one of the six sides surrounded by each of the main body corner frames 1 and each of the main body constituent frames 2 serving as a door mounting opening D0 and which are attached to the other five sides via water-stopping materials 4B (see Figure 2).

[0014] As shown in Fig. 3, each main body corner frame 1 is made of metal such as aluminum die casting, and includes a main body corner central portion 10 that forms the center of each corner of the box shape, a main body corner widthwise extension portion 11 (hereinafter sometimes simply referred to as extension portion 11) that extends from the main body corner central portion 10 in the width direction of the box shape and is connected to the main body frame 2, a main body corner heightwise extension portion 12 (hereinafter sometimes simply referred to as extension portion 12) that extends from the main body corner central portion 10 in the height direction of the box shape and is connected to the main body frame 2, and a main body corner depthwise extension portion 13 (hereinafter sometimes simply referred to as extension portion 13) that extends from the main body corner central portion 10 in the depth direction of the box shape and is connected to the main body frame 2. Each main body corner frame 1 has connecting portions 111, 121, 131 on the main body corner frame side at the extension direction ends of the main body corner widthwise extension portion 11, main body corner heightwise extension portion 12, and main body corner depthwise extension portion 13, respectively.

[0015] In this case, the main body central corner 10 is composed of three faces: a rectangular central face oriented in the height direction of the box, and two rectangular faces on both sides extending at right angles from two adjacent sides of the central face oriented in the width and depth directions of the box, with one side of the central face and one side of the two opposite sides, the other side of the central face and one side of the two opposite sides, and the two opposite sides each having an L-shaped cross section. Each joint between the three faces is formed with rounded corners. The body corner width direction extension 11 is made up of two identical rectangular faces that are continuous with the central face of the body corner central part 10 and one of the two faces on both sides, and extend in the extension direction. The body corner height direction extension 12 is made up of two identical rectangular faces that are continuous with the two faces on both sides of the body corner central part 10, and extend in the extension direction. The body corner depth direction extension 13 is made up of two identical rectangular faces that are continuous with the one face of the body corner central part 10 and one of the two faces on both sides, and extend in the extension direction. The connecting parts 111, 121, 131 of the body corner width direction extension 11, the body corner height direction extension 12, and the body corner depth direction extension 13 are provided by further extending in the extension direction from the extension direction tips of these extension parts 11, 12, 13, as described later. The extensions 11, 12, 13 and the connecting portions 111, 121, 131 are all the same size, and have an L-shaped cross section with rounded corners.

[0016] Each of the main body frames 2 is made of a metal such as aluminum (alumite) and includes a plurality of frames of the same or different lengths. Each of the frames has a connecting portion 20 on the main body frame side at both ends.

[0017] In this case, the main body frame 2 is basically composed of 12 frames, including two frames 21 at the top of the front and back sides of the box shape, two frames 22 at the bottom of the front and back sides of the box shape, four frames 23 in the height direction of the front and back sides of the box shape, two frames 24 in the upper depth direction of the box shape, and two frames 25 in the lower depth direction of the box shape. Each of these frames 21-25 is formed in an L-shaped cross section with rounded corners of the same size as the cross-sectional shape of each extension part 11-13 so that it can be integrally and continuously connected to each extension part 11-13 of the main body corner frame 1, and is formed by cutting the length into multiple types of dimensions according to the width, height, and depth directions of the box shape, and multiple types of main body frames 2 are prepared that have the same cross-sectional shape but different lengths. Note that FIG. 3 shows only a part of the main body frame 2 as an example. As described later, each connecting portion 20 on the main body frame side is formed on the inner surface at both ends of the main body frame 2 as a groove having an L-shaped cross section so that each connecting portion 111-131 on the main body corner frame side can be fitted therein.

[0018] In this case, one of the connecting parts 111-131 on the main body corner frame side or the connecting part 20 on the main body frame side is formed in a protruding piece shape, and the other is formed in a groove-shaped cross section so that one of the connecting parts can be inserted from the tip to slide and embrace one of the connecting parts. Also, one of the connecting parts 111-131 on the main body corner frame side or the connecting part 20 on the main body frame side has both side edges formed in a V-shaped or U-shaped cross section to present a protrusion, and the other has both side edges formed in a V-shaped or U-shaped cross section to present a groove shape so that one of the connecting parts can be fitted, and is formed in a groove-shaped cross section as a whole. A water stop tape (hereinafter referred to as water stop tape 4A) is attached to one of the connecting parts as a water stop material 4A (see FIG. 5).

[0019] In this case, the connecting portions 111-131 on the main body corner frame side are formed in a protruding piece shape, and the connecting portion 20 on the main body frame side is formed in a groove-shaped cross section. As shown in FIG. 4, the connecting portion 111-131 on the main body corner frame side is formed to protrude from approximately half of the inner side of the end surface of each extension portion 11-13 in the thickness direction of the end surface of the end surface of each extension portion 11-13 in a rounded L-shaped cross section that is continuous with the cross-sectional shape of each extension portion 11-13, and is formed in a length slightly shorter than the length of each extension portion 11-13 in the further extension direction of each extension portion 11-13. In addition, both side edges of the connecting portion 111-131 on the main body corner frame side are formed in a V-shaped or U-shaped cross section to present a protrusion. Here, both side edges of these connecting portions 111-131 are protrusions with a V-shaped cross section. In addition, approximately half of the outer side of the end surface in the thickness direction of each extension portion 11-13 of the main body corner frame 1 forms an abutment surface for the connecting portion 20 on the main body frame side. The connecting portion 20 on the main body frame side is cut out at the inner surface of both ends of the main body frame 2 in a cross-sectional shape that allows the connecting portion 111-131 on the main body corner frame side to fit into the inner surface of both ends of the main body frame 2, and is formed into a groove-shaped cross section that allows the connecting portion 111-131 on the main body corner frame side to be inserted from the tip and slide and to embrace the connecting portion 111-131. The connecting portion 20 on the main body frame side is formed into a V-shaped or U-shaped cross section, or in this case, a V-shaped cross section, so that both side edges of the connecting portion 111-131 on the main body corner frame side can be fitted into the connecting portion 20, and the connecting portion 20 as a whole has a groove-shaped cross section. The rear end surface of the groove-shaped cross section that forms the connecting portion 20 on the main body frame side (approximately half of the inner surface in the thickness direction of the main body frame 2) serves as the contact surface for the connecting portion 111-131 on the main body corner frame side.

[0020] In addition, one of the connecting parts 111-131 on the main body corner frame side or the connecting part 20 on the main body component frame side has a concave portion (110) on both sides of its outer surface extending in its length direction, and the other has a convex portion (201) on both sides of its inner surface extending in its length direction so as to be able to fit into the concave portion (110), and one and the other of these connecting parts 111-131, 20 are connected by engaging the concave portion (110) with the convex portion (201).

[0021] In this case, convex portions 201 are provided on both sides of the inner surface of connecting portion 20 on the main body frame side in the length direction, and concave portions 110 are provided on both sides of the outer surface of connecting portion 111-131 on the main body corner frame side in the length direction so that convex portions 201 can fit into them. Convex portions 201 are formed in a convex shape with a rectangular cross section on both sides of the inner surface of connecting portion 20, and concave portions 110 are formed in a concave shape with a rectangular cross section on both sides of the outer surface of connecting portion 111-131. Connecting portion 20 on the main body frame side and connecting portions 111-131 on the main body corner frame side are connected by engaging these convex portions 201 and concave portions 110.

[0022] Furthermore, as shown in Figure 3, the inner edges of each of the six opening edges of each of the main body corner frames 1 and each of the main body constituent frames 2 formed by the connection between them have a concave groove 14 formed in a flat shape concave from the outside to the inside of the box shape, and a water-stopping member 4B (see Figure 2) is provided on the series of concave grooves 14 after each of the main body corner frames 1 and each of the main body constituent frames 2 are connected.

[0023] In this case, a part of the inside of each main body corner frame 1 and each main body constituent frame 2 is formed in a flat shape concave from the outside to the inside of the box shape relative to the remaining outer part, forming a recessed groove 14. By connecting each main body corner frame 1 and each main body constituent frame 2, a series of recessed grooves 14 is formed around the entire periphery of each opening edge of the six sides of the box shape surrounded by these main body corner frames 1 and each main body constituent frame 2.

[0024] The waterproof tape 4A is a double-sided waterproof tape with adhesive applied to both the outer and inner surfaces. In this case, the waterproof tape 4A is attached to each connecting portion 111-131 of each main body corner frame 1 along the tip edge portion (the abutment surface described above) of each extension portion 11-13.

[0025] The waterproof member 4B (see FIG. 2) is made of rubber and is made of a long, thin, flat waterproof packing (hereinafter referred to as waterproof packing 4B), with double-sided adhesive tape attached to one side of the packing. In this case, the waterproof packing 4B is attached to each of the grooves 14 on the inside of each of the main body corner frames 1 and each of the main body constituent frames 2 by the double-sided adhesive tape.

[0026] A door receiving frame 5 for receiving the door is attached to the inner edge of the door mounting opening D0, which is surrounded by the mutual connections of each of the main body corner frames 1 and each of the main body constituent frames 2, via a water-stopping member, in this case the above-mentioned water-stopping packing 4B (see Fig. 2), as shown in Fig. 6. A water-stopping member 4C (see Fig. 8) is attached to this door receiving frame 5, and the door D is attached to the mounting opening D0 via the door receiving frame 5 with this water-stopping member 4C (see Fig. 8).

[0027] 6, the door receiving frame 5 is made up of an outer peripheral receiving portion 51 that abuts along each recessed groove 14 formed by the mutual connection of each main body corner frame 1 and each main body constituent frame 2, a depth direction receiving portion 52 that extends from the inner edge of the outer peripheral receiving portion 51 in the depth direction of the mounting opening D0, and an inner peripheral receiving portion 53 that extends from the inner edge of the depth direction receiving portion 52 in the direction of the mounting opening D. Also, in this case, the door receiving frame 5 is divided corresponding to each recessed groove 14 of each main body corner frame 1 and each main body constituent frame 2, and is made up of four door receiving corner frames 501 that can be fitted from each recessed groove 14 of each main body corner frame 1 along the inner edge of each recessed groove 14, and four door receiving constituent frames 502 that can be fitted from each recessed groove 14 of each main body constituent frame 2 along the inner edge of each recessed groove 14. In addition, since each main body frame 2 of the door receiving frame 5 includes a plurality of frames of the same or different lengths, each door receiving frame 502 also includes a plurality of frames of the same or different lengths accordingly. The door receiving corner frame 501 is made of a metal such as aluminum die casting, and the door receiving frame 502 is made of a metal such as aluminum (alumite).

[0028] 8, the waterproof member 4C is made of a waterproof packing (hereinafter referred to as waterproof packing 4C) that can be fitted from its inner peripheral edge side to the inner peripheral receiving portion 53 of the door receiving frame 5. In this case, the waterproof packing 4C is made of rubber and has a belt-like shape with a U-shaped or C-shaped cross section that can be fitted from its inner peripheral edge side to the inner peripheral receiving portion 53 of the door receiving frame 5, and is attached to the inner peripheral receiving portion 53 across its outer surface and inner surface.

[0029] 7, the door support frame 5 has a door support corner frame 501 and each door support component frame 502 connected to each other via a waterproof material. The waterproof material is the above-mentioned waterproof tape 4A. Each door support corner frame 501 and each door support component frame 502 are joined by the waterproof tape 4A to prevent water from entering between them.

[0030] Thus, as shown in Fig. 3, the box-shaped frame of the case body B is assembled by connecting the main body frames 2 between the main body corner frames 1. At the same time as assembling the box-shaped frame of the case body B, the waterproof tape 4A is scraped up, that is, turned up, by the connecting parts 20 on the connecting parts 111-131 as shown in Fig. 5, and this waterproof tape 4A is compressed and interposed in the shape of a ring between each of the main body corner frames 1 and each of the main body frames 2, making the connections between each of the main body corner frames 1 and each of the main body frames 2 waterproof.

[0031] 9, the five panels 3 are made of metal such as aluminum (alumite), and are formed in a rectangular shape so that they can be fitted into the grooves 14 of the main body corner frames 1 and the main body frames 2, which are surrounded by the mutual connections of the main body corner frames 1 and the main body frames 2, and can be fitted into the five faces excluding the mounting opening D0 surrounded by the main body corner frames 1 and the main body frames 2. The panels 31-33 have three sizes: a panel 31 forming the top or bottom face of the box, a panel 32 forming the right or left side face, and a panel 33 forming the front or back face. Since the main body frames 2 include a plurality of frames of the same or different lengths, the three types of panels 31-33 are also prepared as a plurality of panels of different sizes for each of the three types of panels 31-33, so that they can be fitted into the faces surrounded by the mutual connections of the main body corner frames 1 and the main body frames 2.

[0032] In this way, each main body corner frame 1 and each main body component frame 2 are connected and fixed by bolts 61 and nuts (plate nuts) 62, as shown in Figure 6, and each panel 3 is attached to each main body corner frame 1 or each main body component frame 2 by bolts 61 and nuts 62.

[0033] In this case, bolt insertion holes 60 are drilled in the tip sides of the connecting portions 111-131 of each main body corner frame 1 (see Fig. 3) and both end sides of each main body constituent frame 2 (see Fig. 3) in correspondence with each other, and each main body corner frame 1 and each main body constituent frame 2 are connected and fixed with bolts 61 and nuts 62. Additionally, bolt insertion holes 60 are drilled in each part of the door receiving frame 5 in correspondence with these bolt insertion holes 60, and the door receiving frame 5 is attached by the bolts 61 and nuts 62 to the opening edge of the door mounting opening D0 surrounded by the mutual connections of each main body corner frame 1 and each main body constituent frame 2, via a waterproof packing 4B (see Fig. 2). In this case, as shown in Figure 9, bolt insertion holes 60 are drilled in the corners of the grooves 14 of each main body corner frame 1 and the four corners of each panel 3 corresponding thereto, and each panel 3 is attached to each surface surrounded by the mutual connections of each main body corner frame 1 and each main body component frame 2 by bolts 61 and nuts 62 (see Figure 3) via waterproof gaskets 4B (see Figure 2).

[0034] As shown in Figure 1, the door D comprises four door corner frames D1 which form each corner of the door, at least four door main body frames D2 which are connected between the door corner frames D1 via inter-door frame water stoppers D4A (see Figure 11) and which form a flat frame together with the door corner frames D1, and two door panels D3 (see Figures 13 and 14) which are attached to the outer and inner surfaces surrounded by the door corner frames D1 and the door main body frames D2 via inter-door frame-panel water stoppers D4B (see Figure 13) and form the outer and inner surfaces of the door.

[0035] Each door corner frame D1 is made of metal such as die-cast aluminum, and comprises a door corner central part D10 which forms the center of each corner of the door, a door width direction extension part D11 which extends from the door corner central part D10 in the door width direction and is connected to the door main body constituent frame D2, and a door height direction extension part D12 which extends from the door corner central part D10 in the door height direction and is connected to the door main body constituent frame D2. The extension direction tips of the width direction extension part D11 and the height direction extension part D12 of each door corner frame D1 have connection parts D111, D121 on the door corner frame side (see Figure 10).

[0036] In this case, as shown in Figure 10, each door corner frame D1 is formed into a U-shaped cross section and an L-shape overall with rounded corners, and consists of a central door corner center part D10, a door width direction extension part D11 extending from this door corner center part D10 in the door width direction, and a door height direction extension part D12 extending from this door corner center part D10 in the door height direction.

[0037] Each door body constituent frame D2 is made of metal such as aluminum (alumite) and includes a plurality of door frames of the same or different lengths. Each door body constituent frame D2 has a door body constituent frame side connection portion D20 on both ends.

[0038] In this case, each door body constituent frame D2 has a U-shaped cross section and forms a straight line shape (straight line) as a whole.

[0039] One of the connecting parts D111, D121, D20 on the door corner frame side or the door main body frame side is formed with a C-shaped or U-shaped cross section, and the other is formed with a groove shape having a C-shaped or U-shaped cross section so that one of the connecting parts D111, D121, D20 can fit into it.

[0040] In this case, the connecting portions D111, D121 on the door corner frame side are formed with a U-shaped cross section, and the connecting portion D20 on the door main body frame side is formed with a groove-shaped U-shaped cross section. The connecting parts D111, D121 on the door corner frame side are formed to protrude from approximately half of the inner side in the thickness direction of the tip surface of each extension part D11, D12 of the door corner frame D1, so as to have a U-shaped cross section that is continuous with the cross-sectional shape of each extension part D11, D12, and to a length slightly shorter than the length of each extension part D11, D12 in the further extension direction of each extension part D11, D12. Note that approximately half of the outer side in the thickness direction of the tip surface of each extension part D11, D12 of the door corner frame D1 forms an abutment surface for the connecting part D20 on the door main body frame side.

[0041] In this case, the connecting parts D20 on the door main body frame side are cut out on the inner surface of both ends of the door main body frame D2 in a cross-sectional shape that allows the connecting parts D111, D121 on the door corner frame side to fit into, and are formed into a groove-shaped cross section so that the connecting parts D111, D121 on the door corner frame side can be inserted from the tip to slide and can embrace these connecting parts D111, D121. The rear end faces of the U-shaped cross section that form the connecting parts D111, D121 on the door main body frame side (approximately the inner half of the thickness direction of the door main body frame D2) serve as the abutment surfaces for the connecting parts D111, D121 on the door corner frame side.

[0042] Also, as shown in FIG. 11, one of the connecting parts D111, D121 on the door corner frame side or the connecting part D20 on the door main body frame side has a concave part (D110) on both sides of its outer surface in the length direction, and the other has a convex part (D201) on both sides of its inner surface in the length direction so as to be able to fit into the concave part (D110), and one of the connecting parts D111, D121, D20 and the other is connected by engaging the concave part (D110) with the convex part (D201).

[0043] In this case, convex parts D201 are provided on both sides of the inner surface of the connecting part D20 on the door main body frame side in the length direction, and concave parts D110 are provided on both sides of the outer surface of the connecting parts D111, D121 on the door corner frame side in the length direction so that the convex parts D201 can be fitted in. The convex parts D201 are formed in a convex shape with a rectangular cross section on both sides of the inner surface of the connecting part D20, and the concave parts D110 are formed in a concave shape with a rectangular cross section on both sides of the outer sides of the connecting parts D111, D121. The connecting part D20 on the door main body frame side and the connecting parts D111, D121 on the door corner frame side are connected by engaging these convex parts D201 and concave parts D110.

[0044] Furthermore, on the inner edges forming the opening edges of both the outer and inner faces of each door corner frame D1 and each door main body constituent frame D2 which are surrounded by their connection, these inner edges are formed into a concave flat shape to have a recessed groove D14, and a door frame-panel water-stopping member D4B (see Figure 13) is provided on the series of recessed grooves D14 after each door corner frame D and each door main body constituent frame D2 are connected.

[0045] In this case, a part of the inside of each door corner frame D1 and each door main body frame D2 is formed in a flat concave shape from the outside to the inside of the door shape relative to the remaining part on the outside, forming a concave groove D14. By connecting each door corner frame D1 and each door main body frame D2, a series of concave grooves D14 is formed around the entire periphery of each opening edge on both the outside and inside faces of the door shape surrounded by these door corner frames D1 and door main body frames D2.

[0046] Each of the two panels D3 is made of a metal such as aluminum (anodized) and is formed into a rectangular shape so that it can be fitted into each of the grooves D14 on the outer and inner surfaces surrounded by each door body constituent frame D2, as shown in Figure 14.

[0047] The inter-door frame waterproof material D4A is made of a waterproof tape (hereinafter referred to as waterproof tape D4A) as shown in Fig. 12. As with the above-mentioned waterproof tape 4A, this waterproof tape D4A is a double-sided waterproof tape with adhesive applied to both the outer and inner surfaces. In this case, this waterproof tape D4A is attached to each connecting portion D111, D121 of each door corner frame D1 along the tip edge portion (the above-mentioned abutment surface) of each extension portion D11, D12.

[0048] The door frame-panel water stop member D4B is made of a rubber, elongated, flat water stop packing (hereinafter referred to as water stop packing D4B) similar to the water stop packing 4B described above, and has a double-sided adhesive tape attached to one side of the packing, as shown in Fig. 13. In this case, the water stop packing D4B is attached to each of the grooves D14 on the inside of each door corner frame D1 and each door main body frame D2 by the double-sided adhesive tape.

[0049] Similarly to the case body B, the door body constituent frames D2 and door panels D3 are prepared in different lengths and sizes so as to correspond to the size of the case body B.

[0050] Thus, as shown in Fig. 12, waterproof tape D4A is applied to each connecting portion D111, D121 of each door corner frame D1, and each door main body constituent frame D2 is connected between each door corner frame D1 to assemble a flat door frame. At the same time as assembling this flat door frame, the waterproof tape D4A is scraped up, that is, turned up, by the connecting portion D20 of each door main body constituent frame D2 on each connecting portion D111, D121 of each door corner frame D1, and is compressed and interposed in a ring shape between each door corner frame D1 and each door main body constituent frame D2, making the connection between each door corner frame D1 and each door main body constituent frame D2 waterproof.

[0051] In this way, as shown in FIG. 10, each door corner frame D1 and each door main body frame D2 are connected and fixed with bolts 61 and nuts 62, and as shown in FIG. 14, each door panel D3 is attached to each door corner frame D1 and each door main body frame D2 with bolts 61 and nuts.

[0052] In this case, as shown in Figure 10, bolt insertion holes 60 are drilled in corresponding relation to each other at the tip sides of the connecting parts D111, D121 of each door corner frame D1 and at both ends of each door main body constituent frame D2, and each door corner frame D1 and each door main body constituent frame D2 are connected and fixed by bolts 61 and nuts 62. Furthermore, in this case, as shown in Figure 14, bolt insertion holes 60 are drilled in the corners of the grooves D14 of each door corner frame D1 and correspondingly in the four corners of each door panel D3, and each door panel D3 is attached by bolts 61 and nuts via waterproof gaskets D4B (see Figure 2) within each surface surrounded by the mutual connections of each main body corner frame D1 and each main body constituent frame D2.

[0053] In this way, as shown in FIG. 14(b), the door D is constructed, and the handle H is attached to one side of the door D. In this case, an L-shaped handle made of metal such as zinc alloy die-casting is used for the handle H. The handle H includes a handle receiving seat h0 having an internal shaft hole and penetrating between the outer and inner surfaces of the door D, an operating shaft h11 rotatably inserted into the shaft hole of the handle receiving seat h0, and a handle lever h1 consisting of a grip h12 extending from the base end side of the operating shaft h11, which is the outer surface side of the door D, along the outer surface of the door D, and as shown in FIG. 1, by rotating the handle lever h1, the stopper h2 on the tip side of the operating shaft h11 can be engaged with and disengaged from the frame in the height direction of the main body frame 2 that forms one side of the mounting opening D0 of the case body B, or a stopper receiving portion provided on this frame. The handle H is attached to the door D via any general waterproof structure.

[0054] The door D having such a configuration is attached to the case body B via a hinge E made of metal such as stainless steel, and with a general waterproof structure interposed therebetween.

[0055] 2 to 9 also show an example of assembling the case body B. Note that the waterproof tape 4A is attached in advance on the connecting parts 111-131 on each of the main body corner frames. As shown in FIG. 3, first, the box-shaped frame of the case body B is assembled by connecting 12 main body frames 2 between each of the eight main body corner frames 1. This state is shown in FIG. 6. Then, each main body corner frame 1 and each main body frame 2 are connected and fixed by bolts 61 and nuts 62 through corresponding bolt insertion holes 60 (see FIG. 6). Also, at the same time as assembling the box-shaped frame of the case body B, as shown in FIG. 5, each waterproof tape 4A on each of the connecting parts 111-131 on each of the main body corner frames is scraped up, that is, turned up, by each of the connecting parts 20 on each of the main body frames, and these waterproof tapes 4A are compressed and interposed between each of the main body corner frames 1 and each of the main body frames 2 in the shape of a ring. These waterproof tapes 4A make the connections between each main body corner frame 1 and each main body constituent frame 2 waterproof.

[0056] Next, on the six faces of each main body corner frame 1 and each main body constituent frame 2 surrounded by their mutual connections, a waterproof gasket 4B is attached to one side of the series of grooves 14 using double-sided tape (see FIG. 2).

[0057] 9, the five panels 3 are fitted into the series of grooves 14 on five of the six faces of each of the main body corner frames 1 and main body frames 2 that are surrounded by their mutual connections. Then, each panel 3 is attached to each main body corner frame 1 with bolts 61 and nuts through the corresponding bolt insertion holes 60. This attachment crushes (compresses) the waterproof gasket 4B between each panel 3 and the series of grooves 14 of each of the main body corner frames 1 and main body frames 2.

[0058] 6, the door receiving frame 5 is fitted into the series of grooves 14 of the mounting opening D0 surrounded by the mutual connections of each of the main body corner frames 1 and each of the main body constituent frames 2, and fitted into the surface of the mounting opening D0. Then, the door receiving frame 5 is attached to each of the main body corner frames 1 and each of the main body constituent frames 2 through the corresponding bolt insertion holes 60 with bolts 61 and nuts 62. This attachment crushes (compresses) the waterproof gasket 4B between the series of grooves 14 of each of the main body corner frames 1 and each of the main body constituent frames 2 and the door receiving frame 5.

[0059] This completes the assembly of the case body B.

[0060] 10 to 14 also show an example of assembly of the door D. As shown in FIG. 10, first, four door body constituent frames D2 are connected between four door corner frames D1 to assemble a flat door frame. Then, each door corner frame D1 and each door body constituent frame D2 are connected and fixed by bolts 61 and nuts 62 through corresponding bolt insertion holes 60. At the same time as assembling the flat door frame, the water stop tapes D4A on the connecting parts D111 and D121 on the door corner frame side are scraped up, that is, turned up by the connecting parts D20 on the door body constituent frame side on the connecting parts D111 and D121 on the door corner frame side (see FIG. 12), and these water stop tapes D4A are compressed and interposed between each door corner frame D1 and each door body constituent frame D2 in the shape of a ring. These water stop tapes D4A waterproof the connection between each door corner frame D1 and each door body constituent frame D2.

[0061] Next, a waterproof gasket D4B is attached to one side of a series of grooves D14 on both the outer and inner sides of each door corner frame D1 and each door main body frame D2, which are surrounded by their mutual connections, using double-sided tape (see Figure 13).

[0062] Next, as shown in Figures 13 and 14, two door panels D3 are fitted into a series of grooves D14 on both the outer and inner surfaces of each door corner frame D1 and each door main body frame D2, which are surrounded by their mutual connection. Then, each door panel D3 is attached to each door corner frame D1 by bolts 61 and nuts through the corresponding bolt insertion holes 60. This attachment compresses the waterproof gasket D4B between each door panel D3 and the series of grooves D14 of each door corner frame D1 and each door main body frame D2 (see Figure 13).

[0063] This completes the assembly of door D.

[0064] 1, 2, and 14 show examples of mounting the case body B and the door D. As shown in FIG. 14, hinges E are attached to the upper and lower parts of the side surface of the other side of the door D. Then, as shown in FIG. 1(b), the door D is mounted to the frame in the height direction of each main body frame 2 through the upper and lower hinges E in the mounting opening D0 surrounded by the mutual connections of each corner frame 1 and each main body frame 2, and fitted into the mounting opening D0. The door D is fitted into the mounting opening D0, and as shown in FIG. 2, the handle H is used to engage the stopper h12 with the frame of the case body B or a receiving metal provided on the frame, thereby compressing the watertight packing 4C between the door receiving frame 5 (inner peripheral receiving portion 53) of the mounting opening D0 and the door D.

[0065] This completes the attachment of the door D to the case body B.

[0066] As described above, according to the present case C, the case body B is composed of eight main body corner frames 1 forming each corner of the box shape, at least twelve main body constituent frames 2 which are connected between each of the main body corner frames 1 via waterproof tape 4A and which form a box-shaped frame together with each of the main body corner frames 1, and at least five panels 3 which are attached to the other five sides via waterproof gaskets 4B and form the five sides of the box shape, with any one of the six sides surrounded by each of the main body corner frames 1 and each of the main body constituent frames 2 serving as a door mounting opening D0. In particular, each main body corner frame 1 comprises a main body corner central portion 10 forming the center of each corner of the box shape, a main body corner widthwise extension portion 11 extending from the main body corner central portion 10 in the width direction of the box shape and connected to the main body constituent frame 2, a main body corner heightwise extension portion 12 extending from the main body corner central portion 10 in the height direction of the box shape and connected to the main body constituent frame 2, and a main body corner depthwise extension portion 13 extending from the main body corner central portion 10 in the depth direction of the box shape and connected to the main body constituent frame 2, and connecting portions 111, 121, 131 on the main body corner frame side are provided at the extension direction tips of the main body corner widthwise extension portion 11, main body corner heightwise extension portion 12, and main body corner depthwise extension portion 13 of each main body corner frame 1, respectively. Each main body frame 2 includes a plurality of frames of the same or different lengths, and a connecting portion 20 on the main body frame side is provided at both ends of the frame. Then, one of the connecting parts 111-131 on the main body corner frame side or the connecting parts 20 on the main body frame side, in this case the connecting parts 111-131 are formed in a protruding piece shape, and the other connecting part 20 is formed in a groove-shaped cross section so that the connecting part 111-131 can be inserted from the tip to be slidable and can embrace the connecting part 111-131, and a waterproof tape 4A is attached to the connecting parts 111-131 as a waterproof material. In this way, by connecting the main body frames 2 between the main body corner frames 1, the box-shaped frame of the case main body B can be easily assembled, and by selecting the length of the main body frames 2, it can be assembled to any size.Then, at the same time as assembling the box-shaped frame of case body B, waterproof tape 4A is scraped up on connecting parts 111-131 by connecting parts 20 and compressed between each main body corner frame 1 and each main body constituent frame 2, waterproofing the connections between each main body corner frame 1 and each main body constituent frame 2, thereby providing reliable waterproofing. Furthermore, since the main body corner frame 1 is made of a metal such as aluminum die-cast and the main body constituent frame 2 is inserted and joined to this main body corner frame 1, it is possible to provide a strong structure that is resistant to deformation even when subjected to an external force applied diagonally to the case body B.

[0067] In addition, in this case C, a double-sided waterproof tape with adhesive applied to both the outer and inner surfaces is used for the waterproof tape 4A, so that when the protruding connecting portion 111-131 is inserted into the connecting portion 20 having a groove-shaped cross section and slid, the double-sided waterproof tape is scraped up on the connecting portion 111-131 by the connecting portion 20, and this double-sided tape is compressed into a ring shape between the connections of each main body corner frame 1 and each main body constituent frame 2, so that the ring-shaped waterproof tape 4A can be securely adhered to the edges of both, and waterproofing can be easily and reliably achieved between the connections of these frames.

[0068] Furthermore, in this case C, one of the connecting parts 111-131 on the main body corner frame side or the connecting part 20 on the main body component frame side, in this case, connecting part 111-131 has both side edges formed into a V-shaped or U-shaped cross section to present a protrusion-like shape, and on the other hand, in this case, connecting part 20 has both side edges formed into a V-shaped or U-shaped cross section to present a groove-like shape so that both side edges of connecting part 111-131 can be fitted into it, and connecting part 20 as a whole is formed into a groove-shaped cross section, so that both connecting parts 111-131, 20 can be easily connected, and both connecting parts 111-131, 20 can be reliably connected without any rattling.

[0069] Furthermore, in this case C, one of the connecting parts 111-131 on the main body corner frame side or the connecting part 20 on the main body component frame side, in this case, the connecting part 111-131 has a concave part 110 on both sides of its outer surface extending in the length direction, and the other, in this case, the connecting part 20 has a convex part 201 on both sides of its inner surface extending in the length direction so that it can fit into the concave part 110, and one and the other of the connecting parts 111-131, 20 are connected by engaging the concave part 110 with the convex part 201, so that by using these concave part 110 and convex part 201 as guides, the two connecting parts 111-131, 20 can be connected even more easily, and the engagement of these concave part 110 and convex part 201 can be used to connect the two connecting parts 111-131, 20 more reliably and without rattling.

[0070] Furthermore, in this case C, the inner edges forming the opening edges of each of the six sides formed by the connection of each of the main body corner frames 1 and each of the main body constituent frames 2 have recessed flat edges formed with recessed grooves 14, and a water-stopping member is provided on the series of recessed grooves 14 after each of the main body corner frames 1 and each of the main body constituent frames 2 are connected, so that the water-stopping member can be easily attached to the opening edges of the six sides and water can be easily and reliably stopped between the opening edges of the six sides and the panels 3 and doors D attached to these six sides. In this case, the water-stopping member is made of a long, thin, flat water-stopping gasket 4B, one side of which is attached with double-sided adhesive tape and is attached onto the recessed grooves 14 by this double-sided adhesive tape, so that the water-stopping gasket 4B can be easily and reliably attached to the opening edges of the six sides.

[0071] Furthermore, in this case C, a door receiving frame 5 for receiving the door is attached via a waterproofing member to the inner edge of the mounting opening D0 of the door surrounded by the connection of each main body corner frame 1 and each main body constituent frame 2, and a waterproofing member is attached to the door receiving frame 5, and the door D is attached to the mounting opening D0 via the door receiving frame 5 with the waterproofing member, so that the space between the mounting opening D0 and the door D can be easily and reliably waterproofed. In this case, the door receiving frame 5 is composed of an outer peripheral receiving portion 51 that abuts along each recessed groove 14 of each main body corner frame 1 and each main body constituent frame 2, a depth direction receiving portion 52 that extends from the inner edge of the outer peripheral receiving portion 51 in the depth direction of the mounting opening D0, and an inner peripheral receiving portion 53 that extends from the inner edge of the depth direction receiving portion 52 in the mounting opening D0 direction, so that the door receiving frame 5 can be easily fitted into the mounting opening D0 just by aligning the outer peripheral receiving portion 51 of the door receiving frame 5 with the recessed groove 14. In this case, the water-stopping member consists of a water-stopping gasket 4C that can be fitted into the inner peripheral receiving portion 53 of the door receiving frame 5 from its inner edge side, and this water-stopping gasket 4C is attached to the inner peripheral receiving portion 53, spanning between its outer surface and inner surface, so that the water-stopping member can be easily and reliably attached to the inner peripheral side of the door receiving frame 5, and the space between the door receiving frame 5 and the door D can be reliably waterproofed.

[0072] Furthermore, in this case C, each main body corner frame 1 and each main body constituent frame 2 are connected and fixed by bolts 61 and nuts 62, and each panel 3 is attached to each main body corner frame 1 or each main body constituent frame 2 by bolts 61 and nuts 62. Therefore, each main body corner frame 1 and each main body constituent frame 2 can be easily and reliably connected and fixed, and each panel 3 can be easily and reliably attached together with a waterproof gasket 4B within each surface surrounded by each main body corner frame 1 and each main body constituent frame 2.

[0073] Furthermore, according to Case C, the door D is composed of four door corner frames D1 forming each corner of the door, at least four door main body frames D2 which are connected between each of the door corner frames D1 via inter-door frame water stop materials D4A and which form a flat frame together with each of the door corner frames D1, and two door panels D3 which form the outer and inner faces of the door D and are attached to the outer and inner faces surrounded by each of the door corner frames D1 and each of the door main body frames D2 via inter-door frame-panel water stop members D4B. In particular, each door corner frame D1 is composed of a door corner central part D10 that forms the center of each corner of the door, a door width direction extension part D11 that extends from the door corner central part D10 in the door width direction and is connected to the door main body constituent frame D2, and a door height direction extension part D12 that extends from the door corner central part D10 in the door height direction and is connected to the door main body constituent frame D2, and connecting parts D111, D121 on the door corner frame side are provided at the extension direction tips of the door width direction extension part D11 and the door height direction extension part D12 of each door corner frame D1. Each door main body constituent frame D2 includes multiple door frames of the same or different lengths, and connecting parts D20 on the door main body constituent frame side are provided at both ends of each door main body constituent frame D2. Then, one of the connecting parts D111, D121 on the door corner frame side or the connecting part D20 on the door main body frame side, in this case the connecting parts D111, D121 are formed in a protruding piece shape, and the other connecting part D20 is formed in a groove-shaped cross section so that the connecting parts D111, D121 can be inserted from the tip and slidably moved and can embrace the connecting parts D111, D121, and a water stop tape D4A is attached to the connecting parts D111, D121 as a water stop material between the door frames. In this way, by connecting the door main body frames D2 between the door corner frames D1, the flat frame of the door can be easily assembled, and by selecting the length of the door main body frame D2 according to the size of the case body B, it can be assembled to any size.Then, at the same time as assembling the flat frame of this door D, a waterproof tape D4A is scraped up on the connecting parts D111, D121 by the connecting part D20 and compressed between each door corner frame D1 and each door main body constituent frame D2, and this waterproof tape D4A bonds and waterproofs the connections between each door corner frame D1 and each door main body constituent frame D2, thereby providing reliable waterproof performance.

[0074] In this case, the watertight tape D4A is a double-sided waterproof tape with adhesive applied to both the outer and inner surfaces, so that by inserting and sliding the protruding connecting parts D111, D121 into the connecting part D20 having a groove-shaped cross section and scraping the watertight double-sided tape up over the connecting parts D111, D121 with the connecting part D20, the double-sided tape can be compressed into a ring shape between the connections of each door corner frame D1 and each door main body constituent frame D2 and reliably adhered to the edges of both, easily and reliably sealing off water between the connections of these frames D1, D2.
