Description

The present invention relates to a coffin without fittings and nails, and a knockdown coffin without fittings and nails.

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. In general, a coffin formed into a rectangular parallelepiped is composed of two side plates, two end plates, a bottom plate and a lid plate. A side plate substrate and a side plate main body which are divided into two are provided.

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. Further, in the coffin described in Patent Document 1, the side plate substrate and the side plate main body are fixed by metal hinges. 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 pipes 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 has investigated conventional coffins, coffins that do not use metal fittings and gold nails, and prefabricated coffins. started to develop.

Utility Model Registration No. 3031039

In a conventional coffin as described in Patent Document 1, the side plate is divided into a side plate substrate and a side plate main body in order to facilitate assembly of the coffin. The side plate substrate and the side plate main body are fixed by metal hinges.

Therefore, in order not to use a metal member (hinge), it is conceivable to use combustible dowels to connect the side plate substrate and the side plate main body. However, when a corpse is placed in the coffin, it is necessary to prevent the side plate base and the side plate body from coming off due to the weight of the corpse. There is a need. Therefore, if an attempt is made to construct a coffin that is easy to assemble while all constituent elements are made of combustible materials, the material used for 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. To realize a coffin without metal nails and an assembly type coffin without metal fittings and metal 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 inventors of the present invention, after intensive research, as metal fittings and a coffin without gold nails according to the first aspect of the present invention,

a first dowel made of a combustible material that mechanically joins the side plate substrate and the side plate body;
The first dowels extend obliquely with respect to the direction perpendicular to the bottom plate, and a coffin without metal fittings and metal nails is conceived.

The inventor of the present invention, as a knockdown coffin without metal fittings and gold nails according to the second aspect of the present invention,
A prefabricated coffin without fittings and nails, in which all components are made of combustible materials,
a bottom plate;
a side plate substrate fixed to the bottom plate;
a side plate main body at least part of which is disposed on the side opposite to the bottom plate of the side plate substrate;
a first dowel made of a combustible material that mechanically joins the side plate substrate and the side plate body;

A prefabricated coffin without metal fittings and metal nails is conceived, in which the hole portion into which the first dowel is fitted extends obliquely with respect to the direction perpendicular to the bottom plate.

According to the present invention, the direction in which the first dowel extends and the direction in which the load of the corpse is applied to the bottom plate and the side plate substrate can be made to intersect, so the diameter of the first dowel and the thickness of the side plate main body and the side plate substrate can be increased. It is possible to make it difficult for the first dowels to come off from the side plate main body or the side plate substrate. As a result, the bonding strength between the side plate substrate and the side plate main body can be improved while reducing the weight of the coffin.

At least part of the side plate main body 20b is arranged on the side of the side plate substrate 12 opposite to the bottom plate 10 (Z1 direction). The coffin 100 includes a main body reinforcing member 21a fixed to the inner surface (plate member 22a) of the side plate main body 20a and a main body reinforcing member 21b fixed to the inner surface (plate member 22b) of the side plate main body 20b. The side plate main body 20a includes plate members 22a and 23a, an upper crosspiece 24a, and a lower crosspiece 25a. The side plate body 20b also includes plate members 22b and 23b, an upper crosspiece 24b, and a lower crosspiece 25b.

As shown in FIG. 4, the main body reinforcing member 21a is arranged at a position adjacent to the substrate reinforcing member 15 in the vertical direction. Further, the main body reinforcing member 21b is arranged at a position adjacent to the substrate reinforcing member 16 in the vertical direction. Further, the main body reinforcing member 21a is fixed to the plate member 22a with a bonding member such as an adhesive or a wooden dowel. The main body reinforcing member 21b is fixed to the plate member 22b with a bonding member such as an adhesive or a wooden dowel. The main body reinforcing members 21a and 21b are fixed to the side plate main bodies 20a and 20b, respectively, thereby increasing the mechanical strength of the side plate main bodies 20a and 20b. Also, the joint between the main body reinforcing member 21a and the side plate main body 20a and the joint between the main body reinforcing member 21b and the side plate main body 20b are each fixed with a combustible adhesive. The main body reinforcing members 21a and 21b are, for example, wood and rectangular lumber.

Further, as shown in FIG. 4, the plate members 22a and 23a sandwich the upper crosspiece 24a and the lower crosspiece 25a from both the outside and the inside. The plate members 22b and 23b sandwich the upper crosspiece 24b and the lower crosspiece 25b from both the outside and the inside. Moreover, the insides of the side plate bodies 20a and 20b each include a cavity. Thereby, the coffin 100 can be lightened. Also, as shown in FIG. 4, the lower crosspieces 25a and 25b are in contact with the side plate substrates 11 and 12 when the coffin 100 is assembled, and are in contact with the side plate substrates 11 and 12 before the coffin 100 is assembled. Away from 12.

As shown in FIG. 5 , the upper crosspiece 24 a and the lower crosspiece 25 a extend along the longitudinal direction of the bottom plate 10 . The side plate main body 20a includes a plurality of vertical crosspieces 26a arranged between the upper crosspiece 24a and the lower crosspiece 25a and extending in a direction perpendicular to the bottom plate 10. As shown in FIG. The plurality of vertical beams 26a are arranged at predetermined intervals in the longitudinal direction of the bottom plate 10. As shown in FIG. Although not shown, the side plate main body 20b also has a plurality of vertical crosspieces arranged between the upper crosspiece 24b and the lower crosspiece 25b.

Further, as shown in FIG. 4, the plate member 23a covers the side plate substrate 11 on the X2 direction side (outside). Further, the plate member 23b covers the side plate substrate 12 on the X1 direction side (outside). As a result, the side plate substrates 11 and 12 are not exposed to the outside, so the coffin 100 is improved in design (beauty).

The side plate body 20a includes a crosspiece 29a arranged between the first crosspiece 27a and the second crosspiece 28a. Although only one crosspiece 29a is shown in FIG. 7, for example, a plurality of crosspieces 29a are provided in the longitudinal direction of the bottom plate 10 at equal intervals. Although not shown, the side plate main body 20b is also provided with crosspieces having the same configuration as the crosspieces 29a.

(Composition of the end plate main body)
As shown in FIG. 6, unlike the side plate main bodies 20a and 20b, the end plate main bodies 30a and 30b are constituted by solid plate members that are solid. The end plate main bodies 30a and 30b are attached to the side plate main bodies 20a and 20b by engaging members 60 (see FIG. 9), which will be described later.

(Construction of dowels)
FIG. 8A is a diagram for explaining the extending direction of the dowel 1a. FIG. 8B is a diagram for explaining the extending direction of the dowel 1b. Each of the plurality of dowels 1a and 1b is made of a combustible material, and is, for example, but not limited to, a cylindrical wooden dowel. The plurality of dowels 1a and 1b may be plastic nails, plastic tackers, wooden nails, bamboo nails, polymer resin staple pinnels. The plurality of dowels 1a and 1b may have a shape other than a columnar shape (for example, a square columnar shape, a triangular columnar shape, a conical shape, a square pyramidal shape, or a triangular pyramidal shape).

Also, the plurality of dowels 1a and 1b are arranged at intervals (e.g., equal intervals) in the longitudinal direction. As shown in FIG. 8A, in the first embodiment, the dowels 1a are partly arranged in the side plate main body 20a, and are inclined in the Y1 direction from the side plate main body 20a with respect to the direction (Z1 direction) perpendicular to the bottom plate 10. and extended. The side plate substrate 11 includes holes 11b into which the dowels 1a are fitted. The hole portion 11b extends parallel to the direction in which the dowel 1a extends, and extends obliquely in the Y1 direction with respect to the direction perpendicular to the bottom plate 10 (the Z1 direction in FIG. 8A). As shown in FIG. 4, the dowels 1a are arranged from the side plate main body 20a to the side plate substrate 11 in a state where the dowels 1a are fitted in the holes 11b. Further, in the first embodiment, the dowels 1a are arranged from between the side plate body 20a and the body reinforcing member 21a to between the side plate substrate 11 and the substrate reinforcing member 15. As shown in FIG. It should be noted that "inclined in the Y1 direction (Y2 direction)" means that the tip of the dowel 1a or the dowel 1b is oriented in the Y1 direction (Y2 direction) from the position arranged on the side plate main body 20a or 20b. means

As shown in FIG. 8B, in the first embodiment, the dowels 1b are partly arranged in the side plate main body 20b, and are inclined in the Y2 direction from the side plate main body 20b with respect to the direction (Z1 direction) perpendicular to the bottom plate 10. and extended. The side plate substrate 12 includes holes 12b into which the dowels 1b are fitted. The hole portion 12b extends parallel to the direction in which the dowel 1b extends, and extends obliquely in the Y2 direction with respect to the direction perpendicular to the bottom plate 10 (the Z1 direction in FIG. 4). That is, the dowel 1b and the hole 12b extend in an inclined direction (Y2 direction) opposite to the direction (Y1 direction) in which the dowel 1a and the hole 11b are inclined. As shown in FIG. 4, the dowels 1b are arranged from the side plate body 20b to the side plate substrate 12 in a state where the dowels 1b are fitted in the holes 12b. Further, in the first embodiment, the dowels 1b are arranged from between the side plate body 20b and the body reinforcing member 21b to between the side plate substrate 12 and the substrate reinforcing member 16. As shown in FIG.

Further, as shown in FIG. 8A, an angle θ1 formed between the direction A1 in which the dowel 1a and the hole 11b extend and the direction (Z1 direction) perpendicular to the bottom plate 10 is, for example, 30 degrees or more and 60 degrees or less. , specifically 45 degrees. Further, as shown in FIG. 8B, an angle θ2 formed between the direction A2 in which the dowel 1b and the hole 12b extend and the direction (Z1 direction) perpendicular to the bottom plate 10 is, for example, 30 degrees or more and 60 degrees or less. , specifically 45 degrees.

Further, as shown in FIG. 4, in the first embodiment, the dowel 1a extends parallel to the side plate main body 20a. Further, the dowel 1b extends parallel to the side plate main body 20b. In other words, the dowels 1a and 1b are both orthogonal to the lateral direction (X1 direction) of the coffin 100. As shown in FIG.

According to the above configuration, the direction in which the dowels 1a and 1b extend and the direction in which the load of the corpse is applied to the bottom plate 10 (the Z2 direction) can be crossed. The dowels 1a and 1b can be made difficult to come off from the side plate bodies 20a and 20b and the side plate substrates 11 and 12 without increasing the thickness of the side plate substrates 11 and 12. As a result, the joint strength between the side plate bodies 20a and 20b and the side plate substrates 11 and 12 can be improved while reducing the weight of the coffin 100. FIG.

The dowels 1a and 1b extend parallel to the inner surfaces of the side plate bodies 20a and 20b (the surfaces of the plate members 22a and 22b) and at an angle to the direction perpendicular to the bottom plate 10. The thickness of the side plate main bodies 20a and 20b can be reduced compared to the case where the side plate main bodies 20a and 20b are inclined with respect to the inner surface of the side plate. As a result, the weight of the side plate bodies 20a and 20b can be reduced.

Since the dowels 1a and 1b are slanted in opposite directions, even if the load of the corpse is applied to the bottom plate 10 in one of the directions in which the dowels 1a and 1b incline, Since the dowel 1a or 1b is hooked on the side plate substrate 11 or 12 in the other direction, the side plate substrate 11 can be made difficult to come off from the side plate main body 20a, and the side plate substrate 12 can be removed from the side plate main body 20b. can be made difficult.

(Structure of engagement member)
FIG. 9 is a sectional view for explaining the engagement between the side plate main bodies 20a and 20b and the end plate main bodies 30a and 30b. FIG. 10 is a side view for explaining the configuration of the groove portion 31 of the end plate main body 30a. 11A is a cross-sectional view showing the configuration of the engaging member 60. FIG. FIG. 11B is a sectional view showing part of the end plate main body 30a. As shown in FIG. 9, the side plate bodies 20a and 20b each include an engagement member 60 that engages the end plate bodies 30a and 30b.

As shown in FIG. 9, the engaging member 60 includes a rail member 61 and a square member 62. As shown in FIG. The rail member 61 is fixed to the square member 62 . As shown in FIG. 9, the rail member 61 extends perpendicularly to the bottom plate 10 and is arranged at a position facing the end plate main body 30a. Further, as shown in FIG. 11, a groove portion 31 extending perpendicularly to the bottom plate 10 is formed in the end plate main body 30a. As shown in FIG. 9 , the rail member 61 fits into the groove portion 31 . Thereby, the end plate main bodies 30 a and 30 b can slide along the rail member 61 . As a result, the end plate main bodies 30a and 30b can be slidably attached to and detached from the side plate main bodies 20a and 20b, respectively. Moreover, since the rail member 61 is fixed to the square member 62, the strength of the rail member 61 can be increased even when the side plate main body 20a is lightened.

11A, the width W1 of the portion of the rail member 61 on the side of the groove 31 (tip portion 61a) is larger than the width W2 of the root portion 61b of the rail member 61. As shown in FIG. Further, as shown in FIG. 11B, the width W1a of the bottom portion 31a of the groove portion 31 is larger than the width W2a of the portion 31b of the groove portion 31 on the rail member 61 side. As a result, the side plate main body 20a and the end plate main body 30a are fixed (movement is restricted) in the direction parallel to the bottom plate 10 . Similarly to the side plate body 20a and the end plate body 30a, the side plate body 20a and the end plate body 30b, the side plate body 20b and the end plate body 30a, and the side plate body 20b and the end plate body 30b are fixed in a direction parallel to the bottom plate 10 ( movement is restricted). This makes it difficult for the groove portion 31 to slip out of the rail member 61 . The end plate bodies 30a and 30b are fixed to the side plate bodies 20a and 20b in a direction parallel to the bottom plate 10, and the dowels 1a and 1b are slanted in opposite directions, so that the side plate bodies 20a and 20b are fixed to the bottom plate 10. It becomes even more difficult to come off.

Further, as shown in FIG. 9, the plate member 23a of the side plate main body 20a covers the outside of the rectangular timber 62. As shown in FIG. A member 63 is arranged between the plate member 23 a and the square member 62 .

According to the above configuration, the side plate main bodies 20a and 20b are removed from the bottom plate 10 (side plate substrates 11 and 12), and the end plate main bodies 30a and 30b are removed from the side plate main bodies 20a and 20b. can do.
