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 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 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 overall average weight is about 150g to 170g. Assuming that the annual number of funerals held is 1.3 million, the annual amount of metal and gold nails discarded by cremation is 195 to 221 tons.

In addition, the inventor repeatedly visited more than 150 city halls and crematoriums nationwide, and used it for grave goods, dry ice, and caskets at the time of delivery, which are related to the emission _{of CO 2 and dioxin groups at the crematorium.} It was found that there are common problems such as post-cremation processing problems of metals and gold nails, and damage to the crematorium.

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

As mentioned above, due to the presence of a large amount of metal fittings and gold nails, it is a problem in terms of the dignity of the body that the metal fittings and gold nails scatter during the cremation of the casket and damage the body and ashes. .. 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 harmful 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 site of the crematorium.

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 burial 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 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 components are made of flammable material after diligent research. Specifically, we have come 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, when 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 above, a load of 80 kg was applied, and four adults held the casket, a squeaking noise was heard and the bottom came off. Next, I put a crosspiece 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. Furthermore, in order for an actual funeral company to use it at a funeral, a structure that can be smoothly moved to all hearse and crematorium is required. The developer of the present invention actually produced 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, and the bottom plate. And a plurality of side plates, at least one of the side plates has a stepped portion at the lower end, and the bottom plate has a concave fitting portion on the side surface facing the side plate having the stepped portion. The stepped portion is a protruding portion formed in a convex shape toward the inner surface side of the casket, and includes a protruding portion that fits with the fitting portion of the bottom plate in a state where the bottom plate and the side plate are joined.

According to the present invention, it is possible to provide metal fittings and a casket without gold nails that can withstand a load of about 180 kg and can be smoothly moved when moving to a hearse or a crematorium.

As shown in FIG. 2B, the convex portion 8 is continuously extended from one end to the other end of the side plate 3 along the longitudinal direction of the side plate 3. Similarly, the upper recess 71 and the lower step portion 72 are also continuously extended from one end to the other end of the side plate 3 along the longitudinal direction of the side plate 3. The inner surface side end surface of the casket 1 in the convex portion 8 is flat, and this end surface is on an extension line of the surface of the flat portion 3A. The depth of the upper recess 71 and the depth of the lower step 72 with respect to the surface of the flat portion 3A are equal to each other. In the first embodiment, the convex portion 8 of the side plate 2 and the side plate 3 corresponds to the protruding portion.

Further, in the first embodiment, the side plate 2 is formed with the step portion 2B by scraping one face material (single plate) to form the upper recess 71 and the lower step portion 72. .. Similarly, in the side plate 3, the step portion 3B is formed by cutting a single plate to form the upper recess 71 and the lower step portion 72. That is, in the side plate 2 and the side plate 3, the uncut portion becomes the convex portion 8. The means for forming the convex portion 8 is not limited to this. A portion of the single plate that becomes the step portion 2B or the step portion 3B is scraped off by a uniform thickness, and the convex portion 8 made of another member is fixed to the scraped portion using an adhesive, a flammable nail, or the like. By doing so, the convex portion 8 may be formed.

FIG. 3A is a top view showing the inner surface of the bottom plate 4. Further, FIG. 3B is a cross-sectional view of the bottom plate 4 in the alternate long and short dash line DD of FIG. 3A. FIG. 3C is a cross-sectional view of the bottom plate 4 in the alternate long and short dash line EE of FIG. 3A. That is, FIG. 3B shows a cross section of the bottom plate 4 along the lateral direction, and FIG. 3C shows a cross section of the bottom plate 4 along the longitudinal direction. The bottom plate 4 is a single face material having a uniform thickness throughout. By using one face material for the bottom plate 4, the load bearing capacity of the casket 1 can be increased. Further, as shown in FIGS. 3B and 3C, concave fitting grooves 9 are provided at the ends of the four side surfaces of the bottom plate 4. In the first embodiment, the fitting groove 9 is a groove that fits with the convex portion 8 of the side plate 2 and the side plate 3 in a state where the side plate 2 and the side plate 3 and the bottom plate 4 are joined. That is, the length of the convex portion 8 and the depth of the fitting groove 9 are substantially the same length. In the first embodiment, the fitting groove 9 corresponds to the fitting portion. As shown in FIGS. 3B and 3C, in the bottom plate 4, an upper convex portion 10 is formed on the upper portion (inner surface side of the casket 1) of the fitting groove 9, and a lower convex portion 11 is formed on the lower portion of the fitting groove 9. It is formed. The thickness of the upper convex portion 10 and the thickness of the lower convex portion 11 may be equal to or different from each other.

FIG. 4 is a cross-sectional view of the casket 1 at the alternate long and short dash line AA of FIG. FIG. 4 shows a bottom plate 4, side plates 2 connected to the left and right sides of the bottom plate 4, and a lid plate 5 placed on the side plates 2. As shown in FIG. 4, in the casket 1, the side plate 2 and the bottom plate 4 are joined by fitting the convex portion 8 of the side plate 2 into the fitting groove 9 of the bottom plate 4. Similarly, the convex portion 8 of the side plate 3 is fitted into the fitting groove 9 of the bottom plate 4, so that the side plate 3 and the bottom plate 4 are joined (not shown). Further, the side end portion of the bottom plate 4 is fitted into the stepped portion 2B and the stepped portion 3B of the side plate 2 and the side plate 3, and the convex portion 8 is fitted into the fitting groove 9, whereby the upper convex portion 10 and the bottom plate 4 are fitted. The lower convex portion 11 also fits into the stepped portion 2B and the stepped portion 3B of the side plate. Further, the upper convex portion 10 of the bottom plate 4 is fitted into the upper concave portion 71 of the side plate 2 and the side plate 3. As a result, the degree of coupling between the bottom plate 4, the side plate 2 and the side plate 3 is increased, and the load bearing capacity of the casket 1 can be increased. Hereinafter, the detailed structure of the fitting portion between the bottom plate 4 and the side plate 2 will be described. Since the fitting portion between the bottom plate 4 and the side plate 3 has the same configuration as the fitting portion between the bottom plate 4 and the side plate 2, the description thereof will be omitted.

FIG. 5 is an enlarged view of the lower right end portion of FIG. When the side plate 2 and the bottom plate 4 are joined, the convex portion 8 of the side plate 2 fits into the fitting groove 9 of the bottom plate 4 without a gap. At the same time, the upper convex portion 10 of the bottom plate 4 is fitted into the upper concave portion 71 of the side plate 2 without a gap. Further, the lower convex portion 11 of the bottom plate 4 fits into the lower step portion 72 of the side plate 2. As a result, the load applied to the convex portion 8 of the side plate 2 and the upper convex portion 10 of the bottom plate 4 is dispersed, and the load bearing capacity of the casket 1 can be increased.

Further, the bottom surface of the casket 1 is flush with the bottom surface of the lower convex portion 11 of the bottom plate 4 which is a flat surface material and the bottom surface of the lower end portion of the side plate 2. This makes it possible to move smoothly to hearse and crematorium. It is desirable that the fitting portion between the fitting groove 9 of the bottom plate 4 and the convex portion 8 of the side plate 2 is joined by an adhesive. It is also possible to join the fitting portion between the fitting groove 9 of the bottom plate 4 and the convex portion 8 of the side plate 2 with a flammable nail or the like. There is a possibility that the upper convex portion 10 and the lower convex portion 11 will be damaged. On the other hand, in the case of joining with an adhesive, there is no risk of such damage.

The horizontal length of the side plate 2 is longer than the horizontal length of the side plate 3. Therefore, the horizontal length at which the side plate 2 and the bottom plate 4 are joined is longer than the horizontal length at which the side plate 3 and the bottom plate 4 are joined. Therefore, a larger load is applied to the joint portion between the side plate 2 and the bottom plate 4 than the joint portion between the side plate 3 and the bottom plate 4. Therefore, as shown in FIGS. 2C and 5, the horizontal length of the convex portion 8 provided on the side plate 2 is X, and the horizontal length of the convex portion 8 provided on the side plate 3 is Y (FIG. 2D). (See), it is desirable that the lengths of X and Y have a relationship of X> Y. That is, it is desirable that the area of the fitting portion between the side plate 2 and the bottom plate 4 is larger than the area of the fitting portion between the side plate 3 and the bottom plate 4. However, the relationship between the lengths of X and Y is not limited to this, and can be configured by, for example, the length of the relationship of X = Y or X <Y.

As described above, in the first embodiment, by fitting the convex portion 8 of the side plate 2 and the side plate 3 into the fitting groove 9 of the bottom plate 4, the degree of coupling between the bottom plate 4 and the side plate 2 and the side plate 3 Can be strengthened and firmly joined. That is, the step portion 2B of the side plate 2 and a part of the side surface portion and the upper surface portion of the bottom plate 4 come into contact with each other, and the side plate 2 and the bottom plate 4 have a larger area than simply joining the side end portion of the side plate and the inner surface side of the bottom plate. Can be joined. As a result, even when a contained object such as a corpse is contained, the weight of the contained object can be withstood. Further, by forming the bottom plate 4 with a single plate, a casket that prevents the bottom plate 4 from being deformed is realized.

The joining procedure of the casket 1 described in the present embodiment is not particularly limited. An example of the joining procedure will be briefly described below. First, the convex portion 8 of the side plate 2 is fitted and joined to the fitting groove 9 of the bottom plate 4, and then the convex portion 8 of the side plate 3 is fitted and joined to the fitting groove 9 of the bottom plate 4. The side plate 3 and the side plate 2 are combined and joined.

According to the casket 1 described above, the convex portion 8 of the side plate 2 and the side plate 3 is fitted in the fitting groove 9 of the bottom plate 4, and the bottom surface of the side plate 2 and the side plate 3 and the outer surface of the bottom plate 4 are flush with each other. It has become. Therefore, it can withstand a load of about 180 kg and can be smoothly moved to all hearse and crematorium.

[Second Embodiment]
As described above, one specific embodiment of the present invention has been described, but the above-described embodiment is an example and does not limit the present invention. For example, in the above-described embodiment, the configuration in which the protruding portion (convex portion 8) is formed by scraping the lower portion of the side plate 2 and the side plate 3 of the single plate to form the upper concave portion 71 and the lower step portion 72 has been exemplified. However, the protruding portion may be fitted from the outside of the side plate 2 and the side plate 3. Hereinafter, the configurations of the bottom plate 4, the side plate 2 and the side plate 3 according to the second embodiment of the present invention will be described as different from those of the first embodiment.

FIG. 6A is a diagram showing a state in which the bottom plate 4 and the side plate 2 in the second embodiment are joined. In the second embodiment, the protruding portion is formed as a reinforcing plate 81 which is a member separate from the side plate 2. As shown in FIG. 6A, a reinforcing plate 81 is fitted into the side plate 2 from the outside, and the reinforcing plate 81 fits into the fitting groove 9 of the bottom plate 4. The reinforcing plate 81 and the fitting groove 9 of the side plate 2 and the bottom plate 4 are joined by an adhesive. Further, since the side plate 3 has the same configuration as the side plate 2, the description thereof will be omitted.

FIG. 6B is a diagram showing an inner surface of the side plate 2 in the second embodiment. As shown in FIG. 6B, the side plate 2 of the present embodiment includes an insertion hole 811 for inserting the reinforcing plate 81 in the stepped portion 2B provided at the lower part of the side plate 2. A reinforcing plate 81 is fitted from the outside of the side plate 2 via the insertion hole 811. The number of reinforcing plates 81 to be fitted is not limited to one. For example, as shown in FIG. 6C, the stepped portion 2B provided at the lower part of the side plate 2 may be provided with four insertion holes 812 for inserting the reinforcing plate 81. In the example shown in FIG. 6C, four reinforcing plates 81 are fitted from the outside of the side plate 2 through the four insertion holes 812. As described above, in the second embodiment, the number of the reinforcing plates 81 is not limited, and one or a plurality of reinforcing plates can be used. When a plurality of reinforcing plates 81 are used, the fitting groove 9 on the bottom plate 4 side may be divided into a plurality of fitting portions so as to match the plurality of reinforcing plates 81.

As shown in the second embodiment, the bottom plate 4 and the side plate 2 can be joined by fitting the reinforcing plate 81 from the outside of the side plate 2 and fitting the reinforcing plate 81 into the fitting groove 9 of the bottom plate 4. The reinforcing plate 81 can be formed of any material provided that it is flammable and that the bottom plate 4, the side plate 2 and the side plate 3 can be reliably joined. The reinforcing plate 81 may be formed of a material different from that of the side plate 2 and the side plate 3. For example, by forming the reinforcing plate 81 with a material stronger than the side plate 2 and the side plate 3, it is possible to prevent the reinforcing plate 81 fitted with the bottom plate 4 from being damaged. Further, the side plate 2 and the side plate 3 are made of a flammable material made of a light material, and only the reinforcing plate 81 is made of a stronger flammable material, so that the entire weight of the casket 1 is not increased and the casket is sturdy. 1 can be realized. The material of the reinforcing plate 81 is not limited to this, and for example, the same material as the side plate 2 and / or the side plate 3 may be used.

Further, in the casket 1 according to the second embodiment, the bottom surface of the bottom plate 4 and the bottom surfaces of the side plate 2 and the side plate 3 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.

[Third Embodiment]
Next, the bottom plate 4, the side plates 2, and 3 according to the third embodiment of the present invention will be described with different configurations from the first and second embodiments.

In the second embodiment, the configuration in which the protruding portion is a reinforcing plate 81 having a certain length in the horizontal direction is illustrated. In the third embodiment, the projecting portions are pin-shaped (dowel-shaped) fixing members provided side by side in the horizontal direction.

FIG. 7A is a diagram showing a state in which the bottom plate 4 and the side plate 2 in the third embodiment are joined by a fixing member 82 inserted from the outside of the side plate 2. FIG. 7B is a diagram showing an inner surface of the side plate 2 according to the third embodiment. As shown in FIG. 7B, the stepped portion 2B provided at the lower part of the side plate 2 is provided with a circular insertion hole 821 for inserting the fixing member 82. A plurality of insertion holes 821 are provided at intervals. The intervals between the insertion holes 821 are preferably, but not limited to, equal intervals. The fixing member 82 is, for example, a columnar member. Therefore, the insertion hole 821 is circular. The fixing member 82 can be formed of any material as long as it is flammable and can reliably join the side plate 2 and the side plate 3 to the bottom plate 4. That is, the fixing member 82 may be a wooden dowel, a plastic nail, a plastic tacker, a wooden nail, a bamboo nail, or a staple pinnel made of a polymer resin.

In addition, the material of the fixing member 82 also includes a flammable non-metal material, a flammable plastic material, a flammable glass material (for example, glass fiber, etc.) and the like. Further, even if it is made of metal, flammable metals such as titanium can be used as a material for the fixing member 82. Further, even a shell made of limestone can be used as a material for the fixing member 82.

Further, in the third embodiment, the fitting portion of the bottom plate 4 is formed as a groove 91 described later. As shown in FIG. 7A, the fixing member 82 is fitted from the outside of the side plate 2 and fits into the groove 91 of the bottom plate 4. The fixing member 82 and the groove 91 of the bottom plate 4 are joined by an adhesive. Further, since the side plate 3 has the same configuration as the side plate 2, the description thereof will be omitted.

FIG. 7C is a view when the bottom plate 4 according to the third embodiment is viewed from the side surface side. Further, FIG. 7D is a cross-sectional view of the bottom plate 4 at the alternate long and short dash line FF of FIG. 7C. The fitting portion of the bottom plate 4 in the third embodiment is composed of a groove 91 formed at a position corresponding to the fixing member 82 of the side plate 2. By joining the groove 91 of the bottom plate 4 and the fixing member 82 of the side plate 2 with an adhesive, the degree of coupling between the bottom plate 4 and the side plate 2 is strengthened. The means for joining the groove 91 and the fixing member 82 is not limited to the adhesive. For example, when the fixing member 82 is a flammable wooden nail and a temporary groove having a diameter smaller than the diameter of the wooden nail is provided in advance on the side surface of the bottom plate 4, the wooden nail is used when joining the bottom plate 4 and the side plate 2. A method of joining the side plate 2 and the bottom plate 4 by driving in from the outside of the side plate 2 and fitting the side plate 2 into the bottom plate 4 may also be used.

As shown in the third embodiment, the bottom plate 4 and the side plate 2 can be joined by fitting the fixing member 82 from the outside of the side plate 2 and fitting the fixing member 82 into the groove 91 of the bottom plate 4. By forming the fixing member 82 with a flammable and sturdy material different from the side plate 2, it is possible to prevent the fixing member 82 fitted with the bottom plate 4 from being damaged. For example, the side plate 2 is made of a flammable material made of a light material, and only the fixing member 82 is made of a flammable material made of a material stronger than that of the side plate 2. 1 can be realized. Further, by using the fixing member 82 in the third embodiment as the projecting portion, the weight of the casket 1 can be reduced as compared with the case where the reinforcing plate 81 in the second embodiment is used.
