Description

The present invention includes a door (denoted as “door stone” regardless of whether the material is stone) which seals the ostium (denoted as “gravestone” regardless of whether the material is stone) or not. Related to tombstones.

  Conventional tombstone door stones are door stones that open and close by rotating around an axis provided on the door butt side (hereinafter referred to as “a sliding door”), (for example, refer to both patent documents below), along the bone opening. Examples thereof include door stones (hereinafter referred to as “sliding doors”) that open and close by sliding along provided guides (see, for example, Patent Document 2 below).

For hinged doors, stones have a relatively high specific gravity and are difficult to support in a cantilevered state due to weight balance. If the rotation axis is closer to the center, the ossuary chamber becomes narrower and the opening of the ossuary opening becomes narrower. There is a problem. In addition, the doors are easily invaded by wind and rain, grass, and insects, and water return is often set on the floor of the frontage, but the presence of the water return also becomes a factor that worsens the stool.
With sliding doors, it is difficult for women and elderly people to open and close due to the weight of door stones, etc., and it is often promoted by accumulation of dust, etc. There is also a fear.

  The present invention has been made in view of the above circumstances, and prevents invasion of wind and rain, grass and insects, facilitates the opening and closing of bones that are easy to open and close, and eliminates the possibility of injury to limbs due to the fall of door stones. The purpose is to provide a tombstone with a possible door stone.

  The tombstone according to the present invention for solving the above-mentioned problems is a tombstone comprising a sliding door for opening and closing the ostium of the ossuary chamber, wherein the sliding door is located laterally along the front lower edge of the ossuary port outside the ossuary chamber. And a door stone that is slidably mounted along the track.

The main feature of the track is that the track is provided with a surface receiving portion that supports the door stone from below, and the surface receiving portion adjusts and supports a moment around the center of gravity of the door stone so as to stand upright. It has a horizontal surface or an inclined surface descending to the front side, and the horizontal surface or inclined surface becomes a fulcrum of moment toward the back side of the door stone above the center of gravity of the door stone when the ostium is closed, and the door stone is When opening as a stable standing state according to the principle of the above, a support edge serving as a fulcrum of the insulator is provided, the door stone is fixed to the horizontal surface or the inclined surface of the table receiving portion, and the table surface is A back surface that seals the ostium on the support edge while maintaining a posture separated from a horizontal plane or an inclined surface while being in contact with the support edge, and a step surface that is fixed to the horizontal plane or the inclined surface on the door stone or the track is the horizontal plane or Gauge to be clamped on an inclined surface In providing the separation preventing means.

In order to prevent the intrusion of water, water is continuously drained in a U-shape along the upper edge and the left and right edges of the joint surface provided on the back surface of the door stone or the bone opening facing the joint surface. It is good also as a structure provided with a groove | channel.
The tombstones include not only natural stones but also materials made of materials that can be identified with natural stones in terms of properties required as tombstones, including door stones.

  The door stone can prevent the fall of the tombstone by placing the center of gravity in the lower part of the door stone, and even if it falls, the damage of the upper part of the door stone to surrounding objects (such as the human body) can be reduced. It is easy to wake up again. The inclined surface of the front tread surface is desirable in terms of ease of adjustment and adjustment to the standing stability of the door stone, and the amount of stone material can be reduced, resulting in lighter weight.

  Moreover, the structure provided with a protrusion in the peripheral part of the ostium opening in the said ossuary chamber, and provided with the recessed part which the said protrusion fits in the back surface of the said door stone may be sufficient. The shape of the recess may be a groove structure that is accommodated with substantially the same shape as the ridge, or may be a hole structure that is accommodated with an outer edge having substantially the same shape as the ridge, and the inside of which is cut off.

The tombstone according to the present invention has, as the sliding door, a trajectory extending laterally along the front lower edge of the ossuary mouth outside the ossuary chamber, and a door stone that is slidably placed along the trajectory. The track includes a surface receiving portion that supports the door stone from below, and the surface receiving portion includes a horizontal surface that supports the door stone so as to stand upright or an inclined surface that descends to the front side. When the ostium is closed, it becomes a fulcrum of moment toward the back side of the door stone above the center of gravity of the door stone, and when the door stone is opened as a stable standing state by the principle of the lever, the lever fulcrum The door stone is fixed to the horizontal surface or the inclined surface of the front receiving portion, and the table surface is in contact with the support edge while maintaining a posture separated from the horizontal surface or the inclined surface. To provide a back surface that seals the ostium above the support edge What, in appearance, while providing the integrity of the burial chamber and the door stone, during opening and closing, the standing position of the door stone, only changed by the principle of leverage the support edge as a fulcrum, and easily crypt It is possible to cancel the interference and to move the door sideward like a sliding door.
If the support edge is used effectively, the friction between the track and the door stone can be reduced, so that it can be easily opened and closed for women and elderly people.

  In addition, the front receiving portion is provided with a horizontal surface or an inclined surface that descends to the front side to ease the moment around the center of gravity of the door stone so that the door stone can stand up stably, and prevents the door stone from falling over to the grave attendant. It is possible to prevent the door stone from coming off the track by providing the door stone or the track with a disengagement prevention means that holds the tread on the horizontal surface or the inclined surface. Furthermore, by placing the center of gravity of the door stone in the lower part, it is possible to prevent the tombstone from falling, and the principle of the lever makes it easy to operate and support the door stone. Damage to surrounding objects (such as the human body) can be alleviated and it is easy to wake up again.

On the other hand, the back receiving part is provided with a receiving surface that gives a moment toward the back side above the center of gravity of the door stone on the support edge, so that a sufficient sealing strength can be obtained when sealing the entrance of the ossuary chamber. Can be secured.
In addition, by adopting a structure with a protrusion on the peripheral edge of the ostium opening in the ossuary chamber and a recess with the protrusion fitted on the back of the door stone, it is difficult for wind and rain, grass and insects to enter, Intrusion can also be prevented.

Embodiments of a tombstone according to the present invention will be described below with reference to the drawings.
It should be noted that here, only the description of the burial chamber 1, the sliding door 3, and the tombstones constituting the parts related thereto will be given, and the illustration and description of the meteorite and the like will be omitted.

The example shown in FIGS. 1 to 8 is a tombstone including a sliding door 3 that opens and closes the ossuary opening 2 of the ossuary chamber 1.
The ossuary chamber 1 of the example shown in the figure is configured by surrounding the side with a middle talcite 1a and sealing the upper and lower sides with an upper talus 1b and a lower talc 1c. The ossuary opening 2 is formed by opening a part of the middle headstone 1a that seals one direction of the ossuary chamber 1, and an airway 9 is formed in the middle headstone 1a as necessary.

The sliding door 3 includes a track 4 that extends laterally along the lower front edge of the bone opening 2 provided in the bone chamber 1, and a door stone 5 that is slidably placed along the track 4.
The track 4 in the example shown in FIGS. 1 to 3 includes a support portion 4b and a back support portion 4c with a support edge 4a as a boundary, and the front support portion 4a opens the door stone 5 in a stable standing state. The cradle 4c is provided with a guide surface that faces the lower surface of the door stone 5 that seals the bone opening 2 and is inclined toward the bone chamber 1 side.
In the example shown in FIGS. 4 to 8, the back receiving portion 4 c is not provided, and the support edge 4 a is provided on the side of the front receiving portion 4 b closest to the bone opening 2.

The door stone 5 is provided with a joint surface that follows the peripheral edge of the bone opening 2 on the back surface of the door stone 5 and has a structure in which the upper part is sufficiently thin compared to the lowermost part. A structure in which the center of gravity O is set sufficiently below is adopted.
Further, the door stone 5 includes a front tread surface 5a which is on the front receiving portion 4b and is fixed to the open base.
The door stone 5 may be divided into a plurality of parts in the width direction. However, the joint part may be inclined or provided with a fitting surface such as unevenness so that wind and rain do not enter from the divided part. desirable.

  The track 4 and the door stone 5 relieve the longitudinal moment m1 of the center of gravity O of the door stone 5 by a combination of the inclination (including horizontal) of the open base of the table receiving portion 4b and the inclination of the front tread surface 5a. While maintaining a stable standing state, the center of gravity of the door stone 5 ((dots in FIGS. 4, 6 and 7)) O directly above the support edge (the dashed line in FIGS. 4, 6 and 7) O Is moved to the side of the calcaneal chamber 1 to give a moment m2 toward the back side of the door stone 5 above the center of gravity O of the door stone 5, and the back surface of the door stone 5 is brought into close contact with the periphery of the bone entrance 2 A stable posture is maintained (see FIG. 5).

In the example shown in FIG. 1, the front receiving portion 4 b is provided with an inclined surface that descends on the front side as the open base, and a protruding portion serving as a track disengagement prevention means 6 that holds the stepping surface of the door stone 5 on the inclined surface. In this example, 6a is provided at the lower side of the inclined surface, and the surface 5a of the door stone 5 of the example is a flat surface that uniformly inclines across the front and back of the door stone 5.
The inclined surface may be a plane that follows the step surface 5a or a curved surface on an arc as long as the moment m1 of the longitudinal direction of the center of gravity O of the door stone 5 is relaxed to stabilize the door stone 5 so that it can stand upright. Further, the open base may be a horizontal surface instead of the inclined surface (see FIGS. 6A and 6B). In each case, the support base 4b and the support edge 4a are separated from the support edge 4a. You may form intermittently the receiving part which descends uniformly over the table receiving part 4b.

In the example shown in FIG. 2, the front receiving portion 4b is provided with an inclined surface that descends to the front side as the open base, and is supported as a track separation preventing means 6 that holds the stepping surface 5a of the door stone 5 on the inclined surface. This is an example in which a locking portion is provided above the backing portion 4c beyond the edge 4a, and a flat portion that uniformly inclines on the front side of the door stone 5 is provided as the stepping surface 5a of the door stone 5 of the example. The protrusion 6 a related to the locking portion is provided on the back side of the door stone 5 as the orbit separation prevention means 6.
Further, the open base may be a horizontal surface instead of the inclined surface, and in each of them, a receiving portion that uniformly falls from the support edge 4a to the surface receiving portion 4b at the surface receiving portion 4b and the support edge 4a. May be formed intermittently, or a dent 10 on which the finger is placed on the side surface of the door stone 5 may be provided.

  The example shown in FIG.3 and FIG.5 is provided with the protrusion 7 in the peripheral part of the osteotomy port 2 in the said osteotomy chamber 1, and provided with the recessed part 8 in which the said protrusion 7 fits in the back surface of the said door stone 5. FIG.

  According to the tombstone configured as described above, the door stone 5 closes the bone opening 2 without any gaps due to gravity, so that insects and water can be prevented from entering. If the protrusion 7 is provided and the concave portion 8 into which the protrusion 7 is fitted is provided on the back surface of the door stone 5, it is possible to prevent the blowing of wind and rain without providing the drainage opening 2 with a drain.

  In addition, since the door stone 5 tilting toward the ostium 2 is subjected to gravity, when the ostium 2 is blocked, the door stone 5 can be prevented from falling due to an earthquake or the like, and the door stone 5 is opened. In addition, by the lever principle using the support edge 4a of the track 4 as a fulcrum, the bone opening 2 can be opened relatively easily and the door stone 5 can be brought into a stable standing state. Even when the door stone 5 is retracted to the side, the relatively heavy door stone 5 can be moved without being lifted by sliding on the track 4 (the support edge 4a may be used). The ostium can be opened and closed safely without any burden even if there is no grave attendant. By separating from the ossuary room 1, interference with the ossuary room 1 and the ridge 7 can be avoided at the time of opening and closing, and the surface of the gravestone is damaged. I will not let you.

  In the example shown in FIG. 4, a water draining groove 11 that is continuous in a U-shape is drilled on the joint surface provided on the back surface of the door stone 5 from the upper side to the lower side. This example is a drainage groove 11 that has a U-shape along the upper edge of the door stone 5 and both left and right edges, and drains from the lower left and right sides in a continuous manner. Water that has entered through the gaps at the periphery is collected without allowing water to enter the bone opening 2 and guided to the lower part of the door stone 5. The water draining groove 11 may be formed in the same manner as the water draining groove 11 provided in the door stone 5 at the peripheral edge of the bone opening 2 facing the joint surface of the door stone 5. Accordingly, it may be provided on at least one of the door stone 5 and the peripheral edge of the ostium 2.

The example shown in FIG. 7 is an example in which the eaves 12 or the offering table 14 is provided above the ostium 2, and the example shown in FIG. 7A is provided with a stand 13 on the side of the ostium 2. It is an example, and the example shown in FIG.
If the four-way assembly of the ossuary chamber 1 becomes easy and the strength can be increased, the structure of the ossuary chamber 1 is not damaged by the presence of the door stone 5, the structure is simple, and the track 4 is removable. Since the door stone 5 and the track 4 can be easily replaced individually, the service life is high, and favorable opening and closing can be maintained over a long period of time.

The tombstone according to the present invention is configured as described above, and when the ossuary chamber 1 is opened, the door stone 5 is erected from the state in which the ostium 2 is blocked (see FIG. 8A) (FIG. 8B). ) If the center of gravity O of the door stone 5 is moved right above the receiving portion 4b along the inclination of the open platform, the door stone 5 of the tombstone can be held in a stable standing state on the track 4 (FIG. 8 (C)).
If the front tread surface 5a is slightly lifted in this posture, the skid can be made to slide relatively easily along the support edge 4a of the track 4.

  On the other hand, when closing the ossuary chamber 1, the door stone 5 is placed in front of the ostium 2, the door stone 5 is leaned against the ossuary chamber 1 (see FIG. 8 (D)), and the lower part of the door stone 5 is placed in the ossuary. By pressing against the periphery of the mouth 2, the door stone 5 can completely seal the bone opening 2 (see FIG. 8A). At this time, if the surface 5a is inclined downward from the outside to the inside of the door stone 5, the lower portion of the door stone 5 can be prevented from being separated from the bone opening 2.
