Description

The present invention relates to hardware and nailless coffins.

Conventionally, the main structure of a coffin, which is used to hold a corpse and be cremated, is made of wood, and the box is made of combustible material. Generally, a coffin shaped like a rectangular parallelepiped is composed of two side plates, two end plates, a bottom plate and a cover plate.

Conventionally, joints between the side plate and the end plate, and joints between the bottom plate and the side plate or the end plate have been fixed with metal fittings such as gold nails and Tucker needles, and gold nails. For this reason, the metals and gold nails used for each coffin are 45 to 60 gold nails, 45 to 50 tucker needles, 8 to 12 pin tucker needles, and decorative metal fittings. With 6 to 10 pieces, the average weight of the whole is about 150g to 170g. Assuming that the annual number of funerals is 1,300,000, the annual waste amount of metals, gold nails, etc. due to cremation will be 195t to 221t.

In addition, the inventor of the present application repeatedly visited more than 150 city halls and crematoriums nationwide, and found that burial goods, dry ice, It was found that there were common problems such as the disposal of metals and nails used in coffins after cremation, and damage to cremation furnaces.

Furthermore, looking directly into the cremation furnace and seeing the tragic situation in which metal nails and other objects were pierced into the body and ashes during cremation and the countless metal objects remaining after cremation left a deep pain in my heart. Metals left after cremation are sorted and sorted by disposal companies. The crematorium also had a major problem with damaged plumbing from metal objects.

As mentioned above, due to the presence of a large amount of metal fittings and metal nails, when the coffin is cremated, the metal fittings and metal nails scatter and damage the corpse and the remains, which poses a problem in terms of the dignity of the corpse. . In addition, after cremation, it takes time and effort for on-site staff to collect metal fittings and gold nails, etc., and when metals and gold nails are mixed with the final remaining ash, etc., the pipe is damaged when sucked up by the suction pipe, which requires maintenance. There was also the problem that it took time and money, and some furnaces could not be used.

Also, in general, when metal fittings and metal nails are used in the manufacture of coffins, harmful substances (eg, dioxin or carbon dioxide) are generated when the coffins are burned. The generation of this harmful substance is an important problem to be solved by the government office that has jurisdiction over the crematorium or the person in charge of the crematorium.

From the above, it is preferable to use metal fittings and metal nails as little as possible when manufacturing a coffin. The inventor of the present application had many doubts as to why the above-mentioned tragic facts were not known despite the long passage of time from burial to cremation. I thought I had to do something about it. In order to improve the environment, rationalize the cremation work, and protect the dignity of the corpse and the dignity of the spirit, the inventor of this application started researching conventional coffins and developing a coffin that does not use metal fittings or gold nails. rice field.

In addition, other than the inventor of the present application, development of a coffin with a door that does not use metal fittings and gold nails has been started. For example, Patent Literature 1 discloses a coffin in which a bottom plate and side plates are joined by dowels. In the coffin of Patent Document 1, dowels are arranged from the bottom plate to the side plates. The dowels are formed to extend in a direction perpendicular to the bottom plate.

JP 2020-44305 A

In a conventional coffin as described in Patent Document 1, when a corpse is placed on the bottom plate, the diameter of the dowel and the side plate (side wall part) is designed to be thick. As a result, in conventional coffins, the material used in the coffin increases and the weight of the coffin increases. As the weight of the coffin increases, there is a problem that the bereaved family with weak muscles cannot lift the coffin. In addition, if the material used for the coffin increases, it will take longer to incinerate the coffin (cremation), and the amount of fuel required for cremation will also increase.

SUMMARY OF THE INVENTION One aspect of the present invention has been made in view of the above problems, and an object of the present invention is to reduce the weight of the coffin while improving the joint strength between the bottom plate and the side wall. It is to realize a coffin without nails.

In order to achieve the above object, the inventors of the present invention have actually repeated trial production of metal fittings and coffins without gold nails of the present invention many times to solve the above problems. That is, the inventor of the present invention, as a result of extensive research, as metal fittings and a coffin without gold nails according to one aspect of the present invention,
Metal fittings and nailless coffins in which all components are made of combustible materials,
a bottom plate;
a side wall portion in contact with the bottom plate;
a sidewall reinforcing member joined to the inner surface of the sidewall portion, the sidewall reinforcing member being in contact with the bottom plate;
A first nail member made of a combustible material for mechanically joining the bottom plate and at least one of the side wall portion and the side wall reinforcing member, the nail member extending from the bottom plate to at least one of the side wall portion and the side wall reinforcing member a disposed first nail member of combustible material;
A coffin without metal fittings and gold nails, in which the first nail member extends obliquely with respect to a direction perpendicular to the bottom plate, was conceived.

According to the present invention, the direction in which the first nail member extends and the direction in which the load of the corpse is applied to the bottom plate can be made to intersect. It is possible to make it difficult for the first nail member to come off from the side wall portion or the side wall reinforcing member. Further, since the side wall reinforcing member is arranged at the joint portion between the side wall portion and the bottom plate, the thickness of the entire side wall portion is reduced, and the joint strength between the side wall portion and the bottom plate is increased by the side wall reinforcing member and the first nail member. can be made As a result, it is possible to improve the joint strength between the bottom plate and the side wall while reducing the weight of the coffin.

(3) In addition, in the above-described first and second embodiments, an example is shown in which the bottom plate and the side wall portion are configured such that the protrusion of the bottom plate is arranged at the stepped portion of the crosspiece of the side wall portion, but the present disclosure is not limited to this. For example, like the metal fittings and metal nailless coffin 700 according to the fifth modification shown in FIG. 721a.

(4) In addition, in the first and second embodiments, an example in which the side wall portion and the end wall portion are respectively configured by crosspieces and two plate members is shown, but the present disclosure is not limited to this. . For example, the side wall portion 820 may be composed of one plate member as in the metal fittings and metal nailless coffin 800 according to the sixth modification shown in FIG. 15 . Also, although not shown, the end wall portion may be composed of a single plate member.

(5) In addition, in the first and second embodiments, the example in which the lower end of the side wall and the lower surface of the bottom plate are flush with each other has been described, but the present disclosure is not limited to this. For example, the lower surface of the bottom plate may be arranged above the lower ends of the side walls, and crosspieces may be arranged on the lower surface of the bottom plate.

(6) In addition, in the first and second embodiments, both the nail member joining the bottom plate and the side wall portion and the nail member joining the bottom plate and the end wall portion are inclined with respect to the direction perpendicular to the bottom plate. The present disclosure is not limited to this example. That is, at least one of the plurality of nail members provided on the coffin, which joins the bottom plate and the side wall, should be inclined with respect to the direction perpendicular to the bottom plate.

(7) In the first and second embodiments, as shown in FIGS. 3 and 9, the nail members are arranged so as to extend in the Z1 direction with respect to the side wall portion arranged in the X1 direction from the bottom plate. (first embodiment), or arranged so that the nail member extends obliquely in the X1 direction (outer surface side) with respect to the Z1 direction (second embodiment). Disclosure is not limited to this. As in a coffin 900 according to a seventh modified example shown in FIG. 16, nail members 901 may be arranged so as to extend obliquely in the X2 direction (inner surface 23a side) with respect to the Z1 direction. In this case, the nail member 901 may be arranged across the boundary portion between the side wall portion 20 and the side wall reinforcing member 50 beyond the inner side surface 23a of the side wall portion 20, and the nail member 901 may cross the boundary portion. Further, it may be arranged (driven into) inside the side wall reinforcing member 50 .

The metal fittings and the coffin without gold nails of the present disclosure can also be explained as follows.

The metal fittings and the metal nailless coffin according to the first configuration of the present disclosure are metal fittings and the metal nailless coffin in which all the components are formed of combustible materials, and are in contact with the bottom plate and the bottom plate and a side wall reinforcing member joined to the inner surface of the side wall portion, the side wall reinforcing member being in contact with the bottom plate, and mechanically joining the bottom plate to at least one of the side wall portion and the side wall reinforcing member. a first nail member made of a combustible material that extends from the bottom plate to at least one of the side wall portion and the side wall reinforcing member, the first nail member being the bottom plate; (first configuration).

According to the first configuration, the direction in which the first nail member extends can cross the direction in which the load of the corpse is applied to the bottom plate, so the diameter of the first nail member and the thickness of the side wall are increased. Therefore, it is possible to make it difficult for the first nail member to come off from the side wall portion or the side wall reinforcing member. Further, since the side wall reinforcing member is arranged at the joint portion between the side wall portion and the bottom plate, the thickness of the entire side wall portion is reduced, and the joint strength between the side wall portion and the bottom plate is increased by the side wall reinforcing member and the first nail member. can be made As a result, it is possible to improve the joint strength between the bottom plate and the side wall while reducing the weight of the coffin.

In the first configuration, the first nail member may be arranged from the bottom plate to the portion of the side wall portion on the side of the side wall reinforcing member (second configuration).

Here, when the first nail member is driven into the portion of the side wall on the side of the outer surface, the outer surface of the side wall may be cracked or deformed. According to this method, since the first nail member is arranged (driven in) from the bottom plate to the portion of the side wall portion on the side of the side wall reinforcing member, the outer surface of the side wall portion is cracked and the outer surface is deformed. can be prevented. Since the portion of the side wall portion on the side of the side wall reinforcing member is reinforced by the side wall reinforcing member, it is possible to prevent cracks from occurring in the portion of the side wall portion on the side of the side wall reinforcing member.

In the first or second configuration, the first nail member may be arranged so as to extend parallel to the surface of the side wall portion and inclined with respect to a direction perpendicular to the bottom plate (third configuration ).

According to the third configuration, the first nail member can be arranged so as to be inclined with respect to the direction perpendicular to the bottom plate without increasing the thickness of the side wall.

In the first or second configuration, the first nail member may be arranged to extend obliquely with respect to the plane of the side wall (fourth configuration).

According to the fourth configuration, since the bottom plate, the side wall reinforcing member, and the side wall portion are fixed by the first nail member, the joint strength between the bottom plate, the side wall reinforcing member, and the side wall portion can be improved.

In any one of the first to fourth configurations, the side wall portion may include a crosspiece and a pair of plate members sandwiching the crosspiece from both sides, and the first nail member extends from the bottom plate to at least It may be arranged over crosspieces (fifth configuration).

According to the fifth configuration, the side wall can be made lighter than when the side wall is formed of one solid plate member. In addition, since a space is formed inside the side wall, the combustion time in the crematorium can be shortened, and the amount of fuel used in cremation can be reduced. Since the first nail member is arranged from the bottom plate to the crosspiece (is driven into the crosspiece), the joint strength between the bottom plate and the side wall is stronger than when the first nail member is driven into only a pair of plate members. can be improved.

In any one of the first to fifth configurations, the coffin comprises a gable wall section arranged perpendicular to the side wall in plan view and a gable wall reinforcement member joined to the inner surface of the gable wall section. a second nail member made of a combustible material for mechanically joining the end wall reinforcing member in contact with the bottom plate and at least one of the end wall portion and the end wall reinforcing member to the bottom plate, the second nail member being made of a combustible material; a second nail member made of a combustible material disposed over at least one of the wall portion and the gable wall reinforcing member, the second nail member being inclined with respect to a direction perpendicular to the bottom plate; In addition to extending, the first nail member may be configured to extend obliquely in a direction orthogonal to the direction in which the first nail member inclines (sixth configuration).

According to the sixth configuration, since the first nail member and the second nail member are inclined in different directions, the joint strength of the bottom plate to the side wall portion and the end wall portion is reduced as compared with the case where the first nail member and the second nail member are inclined in the same direction. can be improved.
