Description

[Technical Field]

[0001] The present invention relates to coffins, and more particularly to coffins that are easily assembled. [Background technology]

[0002] Conventionally, coffins are delivered to funeral companies and the like in a fully assembled state, which requires a considerable amount of space for storage and management. Therefore, the inventions described in Utility Model Registration No. 3031039 (Patent Document 1) and Utility Model Registration No. 3228323 (Patent Document 2) propose a prefabricated coffin that can be folded compactly for storage and transportation, and can be assembled on-site (at the ceremony hall).

[0003] However, these prefabricated coffins have problems such as the complicated structure of the connecting parts between the components, which makes them costly, and the joints are exposed after assembly, which makes them look unattractive. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3031039 [Patent Document 2] Utility Model Registration No. 3228323 Summary of the Invention [Problem to be solved by the invention]

[0005] This invention was made to solve the problems with the above-mentioned conventionally proposed prefabricated coffins, and aims to provide a prefabricated coffin that can be folded compactly for storage and transportation, does not require tools for assembly, can be assembled easily and quickly on site (at the ceremony hall), and looks good after assembly. [Means for solving the problem]

[0006] The invention described in claim 1 to solve the above problem is: A coffin consisting of a body and a lid, The main body is composed of a bottom plate, a pair of side surface base members arranged on the long side of the bottom plate, a pair of end surface base members arranged on the short side of the bottom plate, a pair of side plates attached to the side surface base members via hinges, and a pair of end plates assembled between the ends of the pair of side plates, One of the pair of side base members is set lower than the other, a first notch portion into which the side base material is fitted is provided at the lower part of the inner surface of the pair of side plates, and during assembly, the inner surface of the first notch portion comes into close contact with the long side end surface of the bottom plate to conceal that portion; a second cutout portion into which the end surface base material is accommodated is provided at the lower portion of the inner surface of the pair of end plates, and during assembly, the inner surface of the second cutout portion is in close contact with the short end surface of the bottom plate to conceal that portion; This coffin is characterized in that the end plate is attached to the side plate by sliding a slide joint installed on the edge of the side plate into a second joint groove drilled on both end surfaces of the end plate.

[0007] In one embodiment, the slide joint is a rail with a dovetail cross section, and the second joint groove is a corresponding dovetail groove shape, the upper part of which is closed.

[0008] In one embodiment, the sliding joint has a symmetrical rail with a dovetail cross section, one half of which is slidingly fitted into a first joint groove with a closed top drilled on the inner surface of the side plate.

[0013] The coffin of the present invention will be described with reference to the accompanying drawings. The coffin of the present invention consists of a main body 1, which is the storage area, and a lid 20. The main body 1 is composed of a rectangular bottom plate 2, a pair of narrow, long side base members 3a, 3b, a pair of narrow, short end base members 4a, 4b, a pair of side plates 5a, 5b, and a pair of end plates 6a, 6b.

[0014] The side surface base materials 3a and 3b are fixed to the long edge of the bottom plate 2, and the end surface base materials 4a and 4b are fixed to the short edge of the bottom plate 2 (see FIG. 3). One side surface base material 3a is set to be higher (wider) than the other side surface base material 3b. The length of the side plates 5a and 5b is set to be slightly longer than the length of the bottom plate 2.

[0015] First notches 7a, 7b of a size that allows the side surface base materials 3a, 3b to fit into them are provided in the lower part of the inner surface of each side plate 5a, 5b, and when assembled as described below, inner surfaces 7c of first notches 7a, 7b come into close contact with the long side end surface of the bottom plate 2, concealing the long side end surface of the bottom plate 2. Although the side plates 5a and 5b have the same height, the side surface base materials 3a and 3b have different heights, and therefore the heights of first notch 7a on the side plate 5a side and first notch 7b on the side plate 5b side are different (see Figure 7).

[0016] Each side plate 5a, 5b is connected to the side base members 3a, 3b via hinges 12. The hinges 12 are screwed so as to straddle the lower edge of the inner surface of the side plate 5a, 5b and the upper edge of the inner surface of the side base members 3a, 3b. By connecting the side plates 5a, 5b to the side base members 3a, 3b via hinges 12 in this manner, the side plates 5a, 5b can be folded into a compact state during transportation, storage, etc. (see FIG. 7). Note that, because the heights of the side base members 3a and 3b are different, when folding, the side plate 5b on the side of the lower side base member 3b can be folded first, and then the side plate 5a can be folded, allowing them to be folded one on top of the other.

[0017] The pair of end plates 6a, 6b have the same shape, and a second cutout portion 8 of a size that can accommodate the end surface base materials 4a, 4b is provided on the lower part of the inner surface, and when assembled as described below, the inner surface of the second cutout portion 8 comes into close contact with the short side end surface of the bottom plate 2, concealing the short side end surface of the bottom plate 2. Note that, since the end surface base materials 4a, 4b have the same height, the height of the second cutout portion 8 formed in end plate 6a and the height of the second cutout portion 8 formed in end plate 6b are the same.

[0018] The end plates 6a, 6b are independent components that are assembled between the ends of the side plates 5a, 5b via slide joints 9. Preferably, the slide joints 9 are rails with a dovetail cross section that are fixed to the ends of the side plates 5a, 5b.

[0019] As shown in Figure 11, the slide joint 9 can be provided with symmetrical rails with dovetail cross sections. In this case, one half of the rail fits into a first joint groove (dovetail groove) 10 formed in the height direction at the end of the side plates 5a, 5b, and the other half is exposed. Second joint grooves (dovetail grooves) 11 are then drilled into both end faces (edges) of the end plates 6a, 6b, into which the exposed other half slides. The upper ends of the first joint groove 10 and the second joint groove 11 are closed (closed portions 12, 13) to prevent the slide joint 9 from being exposed.

[0020] Small vertically extending uneven portions are formed on the side surface of the slide joint 9. These uneven portions are intended to prevent the side surface of the slide joint 9 from coming into close contact with the inner surfaces of the first joint groove 10 and the second joint groove 11, thereby preventing interference with smooth sliding.

[0021] The coffin body 1 having the above-described structure is assembled in the following manner, but no special locking procedures or tools are required for the assembly. (1) Raise the side panels 5a and 5b. (2) The end plates 6a, 6b are inserted from above between the ends of the side plates 5a, 5b, and the slide joints 9 exposed on the inner surfaces of the side plates 5a, 5b are inserted all the way into the second joint grooves 11, thereby fixing the end plates 6a, 6b between the ends of the side plates 5a, 5b.

[0022] In this way, the main body 1 can be easily assembled, and can also be easily disassembled by performing the reverse operation. [Industrial Applicability]

[0023] The coffin of this invention is constructed as described above, and can be folded compactly for storage and transportation, so it requires little storage space. It can be assembled easily and quickly on site (at the ceremony hall) without the use of tools, and since the joints are not exposed, it looks good, so it has great industrial applicability.
