Description

The present invention relates to metal fittings and a casket without gold nails.

Conventionally, the main structure of the casket for cremation is made of wood and the box is made of flammable material. Generally, the casket formed in a rectangular parallelepiped is composed of two side plates, two end plates, a bottom plate and a lid plate. In addition, the lid plate is provided with a door for worshiping the body.

Conventionally, the joint portion between the side plate and the end plate, and the joint portion between the bottom plate and the side plate or the end plate have been fixed by metal fittings such as gold nails and tacker needles, and gold nails. For this reason, the metals and gold nails used for each casket are 45 to 60 gold nails, 45 to 50 tacker needles, 8 to 12 pin tackers, and decorative metal fittings. With 6 to 10 pieces, the total average weight is about 150 g to 170 g. Assuming that the number of funerals held annually is 1.3 million, the annual amount of metal and gold nails discarded by cremation will be 195 to 221 tons.

In addition, the inventor repeatedly visited more than 150 city halls and crematoriums nationwide, and used it for cremation items, dry ice, and caskets related to the emission _{of CO 2 and dioxin groups at the crematorium.} It was found that the problems of post-cremation treatment of metals and gold nails, damage to the crematorium, etc. were common.

In addition, I looked directly at the inside of the crematorium and was deeply traumatized by the miserable situation in which gold nails and the like pierced my body and ashes during the cremation and the myriad metals left after the cremation. The metals left after the cremation are sorted and sorted by the processor. The crematorium also had major problems with metal pipe damage.

As mentioned above, due to the presence of a large amount of metal fittings and gold nails, the metal fittings and gold nails are scattered during the cremation of the casket, and it is a problem in terms of the dignity of the body that the body and the ashes are damaged. .. In addition, after the cremation, it takes time for the on-site staff to collect the metal fittings and gold nails, etc., and when the metal and gold nails are mixed with the ash that remains in the end and sucked up with the suction pipe, the pipe is damaged for maintenance etc. There was also the problem that it took time and money, and some furnaces could not be used.

In general, when metal fittings and gold nails are used in the production of a casket, harmful substances (eg, dioxin or carbon dioxide) are generated in the combustion of the casket. The generation of this toxic substance has become an important issue to be solved for the government office having jurisdiction over the crematorium or the person in charge at the crematorium site.

From the above, it is preferable not to use metal fittings, gold nails, etc. as much as possible when manufacturing the casket. For example, Patent Document 1 discloses a casket that can be easily assembled in a short time without using metal fittings, gold nails, or the like.

Japanese Unexamined Patent Publication No. 2002-282311

However, the structure disclosed in Patent Document 1 is a structure conceived from the viewpoint of transporting and storing the casket, and from the viewpoint of suppressing the generation of harmful substances, improving the environment, rationalizing the cremation work, and protecting the dignity of the body. It wasn't conceived. Therefore, in Patent Document 1, metal fittings and the like may be used as described above.

Also, why are the above-mentioned tragic facts unknown even though many years have passed since cremation was replaced by cremation? Now that I have a lot of questions and know this fact, I have to do something about it. In order to streamline the cremation work, including improving the environment, and to protect the dignity of the corpse and the dignity of the Spirit, we have begun investigating conventional caskets and developing caskets that do not use metal fittings or gold nails.

As a result, the inventor has come up with a casket in which all the components are made of flammable material after diligent research. Specifically, I came up with a casket that joins a plurality of side plates made of a flammable material by using flammable fasteners instead of metal fittings and gold nails.

On the other hand, in the case of manufacturing a casket in which all the components are made of a flammable material in this way, the load bearing capacity becomes a problem. For example, when a casket was manufactured based on Patent Document 1, a load of 80 kg was applied, and four adults held the casket, a squeak sound was heard and the bottom came off. Next, I put a stile in the bottom plate to make a casket that can withstand the load and used it at a funeral. When I asked the casket maker / funeral company how many kg the load capacity should be, they said that the weights were different, but 120 kg to 150 kg was necessary because fresh flowers were put in grave goods and farewells. Currently, the casket is made of 4 cm to 6 cm gold nails. It is usually manufactured using about 50 gold nails to prevent bottoming out accidents. It was also pointed out that the work cannot be done smoothly unless the bottom of the casket is flat when it is put on a hearse or moved to a crematorium. As described above, considering the total weight of the corpse and grave goods, a high load capacity of about 180 kg is required.

One aspect of the present invention has been made in view of the above problems, and an object thereof is metal fittings and a casket without gold nails that can withstand a load of about 180 kg and can be smoothly moved to all hearse and crematoriums. Is to realize. In addition, in order for an actual funeral company to use it at a funeral, it needs a structure that can be smoothly moved to all hearse and crematoriums. The developer of the present invention actually manufactured the metal fittings and the casket without gold nails of the present invention over and over again to solve all the problems.

In order to achieve the above object, the metal fittings and the gold nailless casket according to one aspect of the present invention are the metal fittings and the gold nailless casket in which all the components are made of a flammable material.
With a bottom plate and multiple side plates,
The bottom plate includes a bottom plate protruding portion protruding upward from the upper surface or a bottom plate fitting portion formed recessed from the upper surface along at least one side of the upper surface of the bottom plate.
Of the plurality of side plates, the side plate joined to the bottom plate protruding portion or the side provided with the bottom plate fitting portion is the side plate fitting portion or the bottom plate fitting portion that receives the bottom plate protruding portion. It is provided with a side plate protrusion that can be accepted.

According to the present invention, by preventing the bottom plate and the side plate from being displaced in the horizontal direction and firmly joining them, it is possible to provide highly durable metal fittings and a casket without gold nails.

FIG. 4 is a cross-sectional view of the casket 100 at the alternate long and short dash line AA of FIG. FIG. 4 shows a bottom plate 140, side plates 120 joined to the left and right of the bottom plate 140, and a lid plate 150 placed on the side plates 120. As shown in FIG. 4, in the casket 100, the side plate 120 and the bottom plate 140 are joined by fitting the bottom plate protruding portion 142 of the bottom plate 140 to the side plate fitting portion 124A of the side plate 120. Similarly, the side plate 130 and the bottom plate 140 are joined by fitting the bottom plate protruding portion 143 of the bottom plate 140 to the side plate fitting portion 134A of the side plate 130. Hereinafter, the detailed structure of the joint portion between the bottom plate 140 and the side plate 120 will be described. Since the joint portion between the bottom plate 140 and the side plate 130 has the same configuration as the joint portion between the bottom plate 140 and the side plate 120, the description thereof will be omitted.

FIG. 5 is an enlarged view of the lower right end portion of FIG. As shown in FIG. 5, in the portion where the bottom plate 140 and the side plate 120 are joined, the bottom plate protruding portion 142 is joined so as to be fitted to the side plate fitting portion 124A without a gap. Similarly, the portion where the bottom plate 140 and the side plate 130 are joined is joined so that the bottom plate protruding portion 143 is fitted to the side plate fitting portion 134A without a gap. Further, when the side plate 120 and the bottom plate 140 are joined, the side end portion of the bottom plate 140 and the lower step portion 124B of the side plate 120 are joined without a gap. That is, as shown in FIG. 5, the bottom plate 140 and the side plate 120 are joined to each other with almost no gap. As described above, the same number of bottom plate protruding portions 142 and side plate fitting portions 124A are provided, and each of the bottom plate protruding portions 142 is fitted to each of the side plate fitting portions 124A. As a result, the bottom plate 140 is firmly bonded to the side plate 120, and in particular, the side plate 120 does not shift in the longitudinal direction of the casket 100 with respect to the bottom plate 140. Similarly, by fitting the bottom plate protruding portion 143 to the side plate fitting portion 134A, the side plate 130 does not shift in the lateral direction of the casket 100 with respect to the bottom plate 140. As a result, it is possible to prevent distortion from occurring between the bottom plate 140 and the side plate 120 and the side plate 130, and to improve the durability of the casket 100.

Further, the bottom surface of the casket 100 is flush with the bottom surface of the bottom plate 140, which is a flat face material, and the bottom surface of the lower end portion of the side plate 120. This makes it possible to move smoothly to hearse and crematorium. It is desirable that the joint portion between the bottom plate protruding portion 142 of the bottom plate 140 and the side plate fitting portion 124A of the side plate 120 is joined by an adhesive. Similarly, it is desirable that the joint portion between the bottom plate protruding portion 143 of the bottom plate 130 and the side plate fitting portion 134A of the side plate 130 is also joined by an adhesive. In this case, since a large area of the adhesive surface between the bottom plate 130 and the side plate 120 and the side plate 130 can be secured, the degree of coupling between the bottom plate 130 and the side plate 120 and the side plate 130 is improved, and the load bearing capacity of the casket 100 is increased. Can be done.

Further, according to the above-mentioned casket 100, the bottom surface of the side plate 120 and the side plate 130 and the bottom surface of the bottom plate 140 are flush with each other. Therefore, it can withstand a load of about 180 kg and can be smoothly moved to all hearse and crematoriums.

In the above configuration, it is assumed that the lower step portion 124B and the lower step portion 134B of the side plate 120 and the side plate 130 are joined to the side end surface of the bottom plate 140 (see, for example, FIG. 5). However, the side plate may be configured to have no lower step portion. In this case, instead of the side plates 120 and 130, the side plates 121 and 131 as shown in FIGS. 6A and 6B are used. The side plate 121 is formed in a concavo-convex shape having a continuous lower end portion. This recessed portion functions as the side plate fitting portion 124A. The lower end of the side plate 131 is formed in a continuous uneven shape, and this concave portion functions as the side plate fitting portion 134A. The side plate 121 and the side plate 131 are configured as a single face material having a uniform thickness, except for the side plate fitting portion 124A and the side plate fitting portion 134A.

FIG. 7 is a cross-sectional view showing the joining relationship between the bottom plate 140 and the side plates 121 and side plates 131 according to the above configuration. As shown in FIG. 7, the bottom plate protruding portion 142 and the bottom plate protruding portion 143 of the bottom plate 140 are fitted to the side plate fitting portion 124A of the side plate 121 and the side plate fitting portion 134A of the side plate 131, respectively, whereby the bottom plate 140 and the side plate are fitted to each other. 121 and the side plate 131 are joined. Further, the side end surface of the bottom plate 140 is flush with the outer surfaces of the side plate 121 and the side plate 131. This configuration also prevents distortion from occurring between the bottom plate 140 and the side plate 121 and the side plate 131, and can improve the durability of the casket 100.

[Second Embodiment]
Hereinafter, regarding the configuration of the bottom plate 240, the side plate 220 (side plate constituting the side surface on the long side side) and the side plate 230 (side plate constituting the side surface on the short side side) of the casket 100 according to the second embodiment, the first aspect is described. The part different from the embodiment will be described.

In other words, at both ends of the short side of the bottom plate 240, there are portions where the bottom plate protruding portion 243 is not provided.

FIG. 10 is an enlarged view of the joint portion between the bottom plate 240 and the side plate 220 in the second embodiment. As shown in FIG. 10, the portion where the bottom plate 240 and the side plate 220 are joined is joined so that the bottom plate protruding portion 242 fits into the side plate fitting portion 224A without a gap. Similarly, in the portion where the bottom plate 240 and the side plate 230 are joined, the bottom plate protruding portion 243 is joined so as to be fitted to the side plate fitting portion 234A without a gap (not shown). Further, when the side plate 220 and the bottom plate 240 are joined, the side end portion of the bottom plate 240 and the stepped portion 224B of the side plate 220 are joined without a gap. That is, as shown in FIG. 10, the bottom plate 240 and the side plate 220 are joined to each other with almost no gap. As described above, since the bottom plate protruding portion 242 is received by the side plate fitting portion 224A, the bottom plate 240 does not shift in the lateral direction of the casket 100 with respect to the side plate 220. Similarly, since the bottom plate protruding portion 243 is received by the side plate fitting portion 234A, the bottom plate 240 does not shift in the longitudinal direction of the casket 100 with respect to the side plate 230. As a result, it is possible to prevent distortion from occurring between the bottom plate 240 and the side plate 220 and the side plate 230, and to improve the durability of the casket 100. Further, it is also possible to join the joint portion between the bottom plate 240 and the side plate 220 and the side plate 230 with an adhesive. In that case, the degree of coupling between the bottom plate 240 and the side plate 220 and the side plate 230 is further improved, and the load bearing capacity of the casket 100 can be increased.

Further, in the casket 100 according to the second embodiment, the bottom surface of the bottom plate 240 and the bottom surfaces of the side plates 220 and the side plates 230 are flush with each other as in the first embodiment. Therefore, it can withstand a load of about 180 kg and can be smoothly moved to all hearse and crematorium.
