Description

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

BACKGROUND ART Conventionally, a casket for storing a corpse for cremation has a wooden main structure and a box body made of a combustible material. Generally, a casket formed in a rectangular parallelepiped is composed of two side plates, two end plates, a bottom plate and a lid plate. Further, the lid plate is provided with a door for worshiping the body.

Conventionally, the joint between the side plate and the end plate and the joint between the bottom plate and the side plate or the end plate have been fixed by metal fittings such as a gold nail or a tucker needle and a gold nail. Therefore, the metal and gold nails used for one casket are 45 to 60 gold nails, 45 to 60 tacker needles, 8 to 12 pin tuckers, and decorative metal fittings. With 6 to 10, the average weight of the whole is as high as 150 g to 170 g. Further, if the number of annual funerals is 1.3 million, the annual amount of metal, gold nails, etc. discarded by cremation will be 195t to 221t.

In addition, the inventor made repeated visits to over 150 city halls and crematoriums nationwide, and used them for burial items, dry ice, and caskets at the time of casket related to the emission of CO ₂ and dioxins in the crematorium. It was found that the common problems such as post-cremation processing of metals and gold nails and damage to the cremation furnace are common.

Furthermore, looking directly into the inside of the cremation furnace, I was deeply hurt by the disastrous situation where gold nails and the like stuck into the body and ashes during cremation, and the myriad of metal that remains after cremation. Metals that remain after the cremation are sorted and sorted by the processor. The crematorium also had major problems with pipe damage from metals.

As mentioned above, due to the presence of a large amount of metal fittings and gold nails, it is a matter of dignity that the metal fittings and gold nails are scattered when the cremation and burning of the coffin and damage the body and bones. .. In addition, after the cremation, it takes time and effort for the staff to collect the metal fittings and gold nails, and when the metal fittings and gold nails are mixed with the ash that remains in the end and the suction pipe sucks up the pipe, it is necessary for maintenance. There is also a problem that it takes time and money, and some furnaces cannot be used.

Further, generally, when metal fittings and gold nails are used in the production of a casket, a harmful substance (eg, dioxin or carbon dioxide) is generated in burning the casket. The generation of this harmful substance has become an important issue to be solved for the officials in charge of the crematorium or the field personnel of the crematorium.

As described above, it is preferable to use metal fittings and gold nails as little 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 gold nails and metal fittings.

JP, 2002-282311, A

However, the configuration disclosed in Patent Document 1 is a configuration 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 cremation work, and protecting the dignity of the body. It was not thought out. Therefore, in Patent Document 1, the metal fittings or the like may be used as described above.

Why isn't such a tragic fact known, even though it has been a long time from burial to cremation? I had to ask a lot of questions and, because I knew this reality, I had to do something about it. In order to streamline the cremation work including environment improvement and to protect the dignity of the body and the dignity of the Spirit, we have begun researching conventional caskets and developing caskets that do not use metal fittings or nails.

As a result, the present inventor, after intensive research, came up with a casket in which all the constituent elements were formed of a flammable material. Specifically, the inventors have come up with a casket that joins a plurality of side plates formed of a combustible material by using a combustible fastener that replaces metal fittings and a nail.

On the other hand, when manufacturing a casket in which all the constituent elements are made of flammable materials in this manner, the load resistance thereof becomes a problem. For example, when a casket was manufactured based on the above-mentioned Patent Document 1 and a load of 80 kg was applied, and four adults held the casket, a quime sound was heard and the bottom fell out. Next, I made a casket that puts a splint on the bottom plate and withstands the load, and used it at a funeral. When I asked the casket maker/funeral company what the load capacity should be, the weight of the casket was different, but it was said that 120kg to 150kg is necessary because fresh flowers are put in burial items and farewells. Currently, the casket is made of 4-6 cm gold nails. It is usually made with about 50 gold nails to prevent the accident of falling out. Also, it was pointed out that the work cannot be moved smoothly unless the bottom of the casket is flat when moving to the cremator when riding on a hearse. As described above, considering the total weight of bodies and burial items, a high load resistance 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 to have no metal fittings and gold nails capable of withstanding a load of about 180 kg and smoothly moving to all hearse cars and cremation furnaces. To realize the casket. Furthermore, in order for an actual funeral company to use in a funeral, it is necessary to have a structure that can be smoothly moved to all the hearse and cremation furnace. The developer of the present invention has actually solved the problems by repeatedly making prototypes of the metal fittings and the nailless casket of the present invention many times.

In order to solve the above problems, the metal fittings and the casket without a metal nail according to an aspect of the present invention are configured such that a plurality of side plates formed of a combustible material are joined together to form a wall surface, and all the constituent elements are combustible. Metal fittings and a casket without a nail made of a flexible material, a step portion is formed at a side end portion, and a bottom plate made of a flammable material is provided. A fitting groove into which the protruding portion of the step portion of the bottom plate is fitted is formed, and the protruding portion of the bottom plate is fitted into the fitting groove of the side plate, and the bottom surface of the side plate and the The bottom plate is flush with the outer surface.

According to the above configuration, the protruding portion of the bottom plate is fitted in the fitting groove of the side plate, and the bottom surface of the side plate and the outer surface of the bottom plate are flush with each other. Therefore, it can bear a load of about 180 kg and can be smoothly moved to all hearse cars and cremation furnaces.

In order to solve the above problems, the metal fittings and the casket without a metal nail according to an aspect of the present invention are configured such that a plurality of side plates formed of a combustible material are joined together to form a wall surface, and all the constituent elements are combustible. A casket without metal fittings and a golden nail, which is made of a flexible material, has a step portion at a side end portion, and is provided with a first bottom plate made of a flammable material, and a lower side of an inner surface of the side plate. A fitting groove into which the protruding portion of the step portion of the first bottom plate is fitted is formed, and the protruding portion of the first bottom plate is fitted into the fitting groove of the side plate, A configuration in which a side end of the bottom surface of the first bottom plate is supported, and a pier formed of a combustible material is provided, and a bottom plate side of the pier is supported, and a second bottom plate formed of a combustible material is provided. Is.

According to the above configuration, the stile supports the side end portion of the bottom surface of the first bottom plate in a state where the protruding portion of the first bottom plate is fitted in the fitting groove of the side plate. Therefore, it is possible to prevent the protruding portion of the first bottom plate from coming off the fitting groove of the side plate. Further, according to the above configuration, the second bottom plate supports the bottom surface side of the pier. Therefore, the metal fittings and the casket without a nail have a so-called double bottom structure. Therefore, it is possible to increase the load resistance of the metal fittings and the casket without the golden nail. Moreover, according to the said structure, since the metal fittings and the bottom part of the casket without a golden nail are comprised by the 2nd bottom plate, when moving to a hearse or a cremation furnace, they can be moved smoothly.

Further, in the metal fittings and the casket without a golden nail according to an aspect of the present invention, the plurality of piers are present, and the side end portion of the first bottom plate is supported by the plurality of piers. Is preferred. According to the above configuration, it is possible to more reliably prevent the protruding portion of the first bottom plate from coming off the fitting groove of the side plate.

In addition, in the metal fittings and the casket without a nail according to an aspect of the present invention, it is preferable that the second bottom plate supports a bottom surface side of each of the plurality of the piers. According to the above configuration, the load resistance of the metal fittings and the coffin without gold nails can be further increased.

Further, the metal fittings and the casket without a nail according to an aspect of the present invention include a lid plate formed of a flammable material, and a plurality of core materials formed of a flammable material on the bottom surface side of the lid plate. A core assembly configured by a combination of the above may be provided. According to the above structure, the strength of the cover plate can be increased.

According to one aspect of the invention, it can withstand a load of about 180 kg. It can also be moved smoothly when moving to a hearse or crematorium. Furthermore, since metal fittings and gold nails are not used for the casket, the following effects are obtained. [1] Can "protect the dignity of the body". Bereaved families will be pleased. [2] The cremation time can be shortened. Along with this, the waiting time for the bereaved family can be shortened and the cremation process can be made more efficient. [3] There is no need to remove metal fittings and gold nails after burning the casket. In addition, it is not necessary to regularly collect metal fittings and gold nails. Therefore, the burden on the person in charge of the removing work and the collecting work is eliminated, and the labor of the person in charge of cremation can be reduced. As a result, labor costs at the crematorium can be reduced.
