Description

The present invention relates to a sleeve tile.

The sleeve tile is a tile installed at a position that covers the roof tile. Therefore, as shown in FIG. 13, the sleeve tile 100 has a tile portion 101 that covers the roof and a fin portion 102 that covers the side surface of the house, and has a structure in which these are vertically combined with each other.

There are two types of sleeve tiles 100, one is called the right sleeve tile shown in FIG. 13 and the other is called the left sleeve tile. When the sleeve tile 100 is installed on the roof, the direction facing the sleeve tile 100 is determined. Therefore, the sleeve tile 100 in which the fin portion 102 hangs down from the right edge portion of the roof tile portion 101 in the direction facing the roof tile is called a right sleeve tile, and the sleeve tile 1 in which the fin portion hangs down from the left edge portion of the roof tile portion. However, it is called a left sleeve tile.

When the sleeve tile 100 is roofed, the fin portion 102 covers the gable plate provided near the keraba on the side surface of the house. Therefore, when it rains diagonally, the fin portion 102 suppresses the rain from hitting the gable board, so that the gable board is prevented from sucking rainwater and corroding (see, for example, Patent Document 1).

Registered Utility Model No. 3134265 Gazette

By the way, for example, the wind blown from the front to the roof is divided into left and right when it hits the roof, and blows toward the left and right keraba sides. On the other hand, the rainwater that has fallen on the roof flows down on the tile portion 101 of the sleeve tile 100 thatched on the roof. However, a part of the rainwater that flows down does not flow to the front sleeve tile 100 even if it reaches the front side surface of the tile portion 101 of each sleeve tile 100, and the surface tension causes the head tile 104 to flow. May be attached.

Therefore, in the event of wind and rain, the rainwater attached to the head Mitsuke 104 may flow on the head Mitsuke 104 toward the fin portion 102. Then, the flow of the water induces the rainwater that flows down on the tile portion 101 of the sleeve tile 100 thatched on the roof, and the induced rainwater induces another rainwater, so that a large amount of rainwater is generated. There was a risk of flowing on the fin portion 102 toward the fin portion 102 of the sleeve tile 100. In this way, when a large amount of rainwater flows over the fin portion 102, some of the rainwater that has reached the lower end of the fin portion 102 wraps around to the back surface side of the fin portion 102 and reaches the gable plate, and the gable plate is formed. There was a risk of corrosion.

Therefore, an object of the present invention is to provide a sleeve tile capable of suppressing the inflow of rainwater into the fin portion.

The sleeve tile according to the invention according to claim 1 is a sleeve tile having a tile portion and a fin portion hanging from an edge portion of the tile portion, and the sleeve tile is assembled with a sleeve tile assembled on the front side. Occasionally, it is provided with an egri portion that forms a space in which the tile portion of the sleeve tile is recessed so that an opening is formed in the head ridge, which is the front side surface of the tile portion of the sleeve tile.

With this sleeve tile, even if the rainwater attached to the head pit flows toward the fin part due to surface tension, when the rainwater reaches the opening of the egg part, the rainwater will flow from the head mitsuke at the end of the opening. Will be done. Then, the peeled rainwater will flow down on the tile part of the sleeve tile assembled on the front side.
Therefore, the sleeve tile of the present invention can prevent the rainwater from flowing into the fin portion of the sleeve tile assembled on the front side even if rainwater adheres to the head due to surface tension.

As described in claim 2, the surface of the tile portion may be provided with a water return portion that rises from the edge portion on the fin portion side and extends along the edge portion on the fin portion side. In this case, the egri portion may be a space in which the back surface of the tile portion is recessed so as to be large enough to accommodate the water return portion of the sleeve tile on the front side when assembled with the sleeve tile on the front side of the sleeve tile. good. Further, when the water return portion of the sleeve tile on the front side enters, the egri portion is on the side opposite to the side where the fin portion of the sleeve tile is located when viewed from the water return portion of the sleeve tile on the front side. It may form a space having a size in which an opening is formed in the head of the roof tile.

Since this sleeve tile has a water return part at the edge on the fin part side, rainwater flowing toward the fin part side attached to the head of the sleeve tile on the rear side will be peeled off at the opening of the egg part. Even if the roof tiles are turned toward the fins, the water return section suppresses the rainwater from flowing to the fins.

Moreover, in this sleeve tile, when the front sleeve tile is combined, the water return part of the front sleeve tile enters the egri part, and when the water return part enters, an opening is formed in the head. Since the Eguri portion is formed to a size that allows the water to return, it is not necessary to form a recess for the water return portion separately from the Eguri portion.

Therefore, by providing the water return portion, the sleeve tile of the present invention can suppress the flow of rainwater to the fin portion in addition to the effect of forming an opening in the head Mitsuke.
Further, since the sleeve tile of the present invention is formed in such a size that the egri portion can accommodate the water return portion of the sleeve tile combined on the front side, the egri portion and the recess into which the water return portion enters are separated. The structure can be simplified as compared with the case of forming the roof tile.

As described in claim 3, the tile portion may be formed on the edge portion on the fin portion side of the tile portion and may include a headrace extending along the edge portion on the fin portion side. In the headrace, the tip portion located on the front side of the tile portion may be inclined toward the edge portion side opposite to the edge portion side provided with the fin portion.

Since this sleeve tile has a headrace on the edge of the fin, even if the rainwater peeled off from the egg is directed toward the fin on the tile, the rainwater will still be on the fin. The headrace prevents it from flowing into.

Moreover, in this sleeve tile, the tip of the headrace located on the front side of the tile portion is inclined toward the edge side opposite to the edge side where the fin portion is provided, so that the headrace canal The rainwater that has fallen on the sleeve tiles on the front side flows toward the side opposite to the fin part side.

Therefore, the sleeve tile of the present invention is provided with a headrace so that rainwater peeled off from the egri portion can be prevented from flowing to the fin portion.
Moreover, in the sleeve tile of the present invention, the tip portion of the headrace is inclined toward the side opposite to the fin portion side, so that when rainwater flows out to the sleeve tile on the front side, it is opposite to the fin portion side. Since it is pushed out to the side, it is possible to prevent rainwater flowing through the headrace from flowing to the fin portion.

As described in claim 4, the tile portion may be provided with a headrace formed at the edge portion on the fin portion side and extending along the edge portion on the fin portion side. The headrace is located on the side opposite to the fin side when viewed from the opening of the Eguri part, and has a release point for pouring rainwater into the sleeve tile on the front side at a position away from the opening of the Eguri part. May be.

Since the release point of the headrace is located away from the opening of the Eguri part on the opposite side of the fin part, rainwater from the release point is attached to the head and toward the fin part side. However, it becomes difficult to reach the opening of the egg.

Therefore, in the sleeve tile of the present invention, it is difficult for rainwater flowing through the headrace to reach the opening of the egri portion, so that in addition to the effect of forming an opening in the head, the rainwater is further to the front side. It is possible to suppress the flow to the fin portion of the assembled sleeve tile.

As described in claim 5, the sleeve tile is a space in which the back surface of the tile portion is recessed in the egri portion, and the headrace is formed by recessing the surface surface of the tile portion and is assembled on the rear side. At least a part of the egri portion provided on the tile portion of the sleeve tile may be formed at a position facing each other.

Since this sleeve tile faces the egri portion, which is a space in which the back surface of the tile portion is recessed, at least a part of the headrace channel in which the surface of the tile portion is recessed is located, the eguri portion is opened. An opening larger than the opening will be formed in the portion. Therefore, the rainwater that has flowed on the head Mitsuke toward the opening of the Eguri portion is surely removed from the head Mitsuke as compared with the case where there is only the opening of the Egli portion.

Therefore, in the sleeve tile of the present invention, even if rainwater is attached to the head plate due to surface tension, the rain water flows to the fin portion side, as compared with the case where the opening of the egri portion is only opened by the head plate. It can be suppressed.

As described in claim 6, the opening of the egri portion may have a length of 3 mm or more in the width direction along the direction from the opening toward the fin portion on the head Mitsuke.
From the experiment, it can be confirmed that when the opening of the egri portion is 3 mm or more, the effect that rainwater is less likely to be transmitted to the fin portion can be confirmed.
Therefore, the egri portion may be formed in a size such that the opening has a width of 3 mm or more. Further, since the effect is particularly large when the opening is 4 mm or more, the egri portion may be formed in a size such that the opening has a width of 4 mm or more.

As described in claim 7, the roof tile portion of the sleeve tile has a sleeve that is assembled on the rear side of the surface of the roof tile portion of the sleeve tile when the sleeve tile is assembled with the sleeve tile on the rear side. A tail groove may be formed in a portion where the tile portions of the tile overlap. The tail groove may be formed on the rear edge portion of the tile portion provided on the sleeve tile, and may be formed from the edge portion provided with the fin portion provided on the sleeve tile to the opposite edge portion.

In the sleeve tile, rainwater may infiltrate the portion of the surface of the tile portion where the tile portion of the sleeve tile assembled on the rear side overlaps. However, if it is configured like this sleeve tile, rainwater that has entered the part where the tile parts of the sleeve tiles assembled on the rear side overlap, for example, from the edge portion where the fin portion is provided to the opposite edge portion. You can send it and let it go out.

Therefore, the sleeve tile of the present invention can prevent rainwater from staying in the portion where the tile portions of the sleeve tile assembled on the rear side overlap.

An exemplary embodiment of the present invention will be described below with reference to the drawings.
This description will be given in the order of 1) the shape of the sleeve tile of the present embodiment, and 2) the function and characteristic effect of the sleeve tile of the present embodiment.
1) Shape of sleeve tile Here, 1-1) the overall shape of the sleeve tile will be explained, and then 1-2) the detailed shape of the sleeve tile will be explained.

1-1) Overall shape of the sleeve tile As shown in FIG. 1, the sleeve tile 1 of the present embodiment includes a tile portion 3 that covers the roof when installed on the roof, and a fin portion 5 that covers the side surface of the house. ing. Both the tile portion 3 and the fin portion 5 are formed in a substantially rectangular plate shape. In the sleeve tile 1, one edge portion along the longitudinal direction of the tile portion 3 and one edge portion along the longitudinal direction of the fin portion 5 are aligned with each other, and the fin portion 5 is provided with respect to the tile portion 3. The tile portion 3 and the fin portion 5 are integrally formed in a shape in which the tile portion 3 and the fin portion 5 are integrally arranged in a vertically arranged state.

Here, the directions used in the following description will be described.
The direction of the sleeve tile 1 facing the roof is fixed. Therefore, each direction means the following directions. That is, the front is one end side in the longitudinal direction of the roof tile portion 3 and faces the eaves side of the roof, and the rear is the other end side in the longitudinal direction of the roof tile portion 3 and faces the ridge side of the roof. Means.

The left side is on a plane parallel to the plate surface of the tile portion 3, and is the direction facing the left side when the front side to the rear side of the tile portion 3 is viewed, and the left side when the ridge side is viewed from the eaves side. The right side is the direction facing the right side when looking at the rear side from the front side of the tile part 3 on a plane parallel to the plate surface of the tile part 3, and the ridge side is seen from the eaves side. It means the direction to face to the right when

The upper part is the direction opposite to the direction in which the fin part 5 hangs down when viewed from the tile part 3, and means the direction toward the sky when the roof is covered, and the lower part is the direction when the fin part 5 is seen from the tile part 3. This is the direction in which the portion 5 hangs down, and means the direction in which the base of the roof faces when the roof is laid.

Here, the shape of the sleeve tile 1 of the present embodiment will be described again using the above-mentioned direction. The sleeve tile 1 is a so-called left sleeve tile in which the fin portion 5 hangs down from the left edge portion of the tile portion 3. It is formed in a long shape in the front-back direction.
In the following description, the so-called left sleeve tile will be described, but the sleeve tile 1 of the present embodiment may be a right sleeve tile in which the fin portion 5 hangs down from the right edge portion of the tile portion 3. In that case, the right-sleeve tile has a plane-symmetrical structure with respect to the plane perpendicular to the left-sleeve tile in the left-right direction.

1-2) Detailed shape of the sleeve tile Here, 1-2-1) the shape of the tile portion 3 will be described, and then 1-2-2) the shape of the fin portion 5 will be described.
1-2-1) Shape of the tile portion 3 As shown in FIG. 2A, the tile portion 3 is on the upper side of the surface 30 of the tile portion 3 (the surface opposite to the side on which the fin portion 5 hangs down). When viewed from above, it is formed in a substantially rectangular shape. The front side 300 and the rear side 301 are substantially parallel to each other, and the front side 300 is slightly longer than the rear side 301. The right side 302 and the left side 303 are formed to have substantially the same length, but are inclined outward from the rear side toward the front side.

As shown in FIG. 1, the tile portion 3 has a curved portion 31 formed on the front side. The curved portion 31 is a portion in which the front portion of the tile portion 3 is curved downward in a substantially bow shape.
The front side surface 32 of the tile portion 3 forms a surface perpendicular to the front-rear direction. The side surface 32 has a width in the vertical direction substantially the same as the thickness of the tile portion 3, and is formed in a long shape along the horizontal direction. This side surface 32 is hereinafter referred to as a head Mitsuke 32.

The roof tile portion 3 is a contact surface 33 that abuts on the front side sleeve tile 1 when the sleeve tile 1 is assembled back and forth, and is substantially perpendicular to the head Mitsuke 32 on the back surface 40 side of the tile portion 3. A bent contact surface 33 is formed. The contact surface 33 has a width substantially the same as that of the head Mitsuke 32, and is a surface formed in a long shape along the left-right direction like the head Mitsuke 32.

An egri portion 34 is formed on the contact surface 33. The contact surface 33 is formed so that the end portion on the fin portion 5 side is one step lower than the other portion when the tile portion 3 is viewed from the lower side (see FIG. 1B). The egg-shaped portion 34 refers to this one-step lower portion. When the sleeve tile 1 is assembled back and forth, the egri portion 34 forms a space large enough to accommodate the water return portion 35 formed on the sleeve tile 1 on the front side, which will be described later. Moreover, the egri portion 34 is a space having a width of about 6 mm along the left-right direction when the water return portion 35 formed on the sleeve tile 1 on the front side is inserted when the sleeve tile 1 is assembled back and forth. Is formed in a size formed on the right side of the water return portion 35 formed on the sleeve tile 1 on the front side (see FIG. 4).

The tile portion 3 has a water return portion 35 and a headrace 36 formed on the edge portion of the surface 30 on the fin portion 5 side (left side).
The water return portion 35 is formed in a shape that is raised at a position in contact with the left side of the surface 30 of the tile portion 3 and extends along the left side of the surface 30 of the tile portion 3. The water return portion 35 is provided from the rear edge portion of the tile portion 3 to the front end portion.

The headrace 36 is formed by recessing a portion of the surface 30 of the tile portion 3 adjacent to the water return portion 35 on the right side of the water return portion 35. The headrace 36 is provided from the rear edge portion of the tile portion 3 to the front end portion. Since the headrace 36 is formed at a position adjacent to the water return portion 35 on the right side of the water return portion 35, when the sleeve tile 1 is assembled back and forth, it becomes an egri portion 34 of the sleeve tile 1 on the rear side. The water return portion 35 is inserted and is located at a position facing the space created to the right of the water return portion 35.

The tip portion 360 on the front side of the headrace 36 is formed in a shape inclined toward the right side. The tip portion 360 is inclined so as to position a release point 361 for pouring rainwater into the sleeve tile 1 on the front side for the water flowing through the headrace 36 at a position away from the egri portion 34 (FIG. 5).

The release point 361 is located on the side opposite to the water return portion 35 when viewed from the egri portion 34, and is preferably located at a position 10 mm or more, more preferably 20 mm or more away from the right end of the egri portion 34. This is because if it is less than 10 mm, the water flowing down the release point 361 is likely to be directly applied to the egri portion 34, and may easily enter the overlapping portion of the sleeve tile 1.

The tile portion 3 has a tail water return portion 37 and a tail groove 38 formed on the rear edge portion of the surface 30.

The tail water return portion 37 is formed in a shape that is raised at a position in contact with the rear side of the surface 30 of the tile portion 3 and extends along the rear side of the surface 30 of the tile portion 3, and is formed at the rear end. It is continuous with the water return part 35.
The tail groove 38 is formed by recessing a portion of the surface 30 of the tile portion 3 adjacent to the tail water return portion 37 on the front side of the tail water return portion 37. The tail groove 38 is provided from the left edge portion of the tile portion 3 to the right edge portion. The tail groove 38 is connected to the headrace 36 at the left edge. The bottom of the buttock groove 38 is inclined downward from the left edge side toward the right edge side.
The tile portion 3 has two nail holes 39. These nail holes 39 are arranged diagonally so as not to be lined up in the front-rear direction or the left-right direction when the other nail hole 39 is viewed from one nail hole 39.
The reason why the tile portion 3 has two nail holes 39 arranged diagonally is as follows.
The base of the roof is composed of a complex combination of base members. However, members having various dimensions are used for this base member. In addition, the installation positions of these base members also vary depending on the roof. Therefore, when the sleeve tile 1 of the present embodiment is roofed, it is necessary to drive a nail into a base member whose position is unknown to fix it. Then, when the two nail holes 39 are arranged so as to be arranged in front and back or side by side, there is a possibility that none of the nail holes 39 is located at a position facing the base member. However, if the two nail holes 39 are arranged diagonally, there is a high possibility that one of the nail holes 39 will be located at a position facing the base member when the sleeve tile 1 is laid. Therefore, in the present embodiment, the tile portion 3 has two nail holes 39 arranged diagonally.
However, if it is known that all the nail holes 39 are arranged at positions facing the base member when the sleeve tile 1 is laid, these nail holes 39 may be arranged side by side or side by side. ..

The tile portion 3 is provided with a support portion 41 on the right edge portion of the back surface 40. The support portion 41 is raised at a position adjacent to the right side of the back surface 40, and is formed in a long shape along the right side of the back surface 40. The support portion 41 is provided from the rear end portion to the front end portion.
At the top of the support portion 41, a contact portion 42 that forms a flat surface on the same surface as the inclined portion 63, which will be described later, is formed on the fin portion 5.

1-2-2) Shape of the fin portion 5 As shown in FIG. 2B, the fin portion 5 has the upper side 500 and the lower side when the surface 50 is viewed from the left side of the sleeve tile 1. The side 501 is formed into a shape having the following shape. The upper side 500 is formed in a shape that is curved downward in accordance with the shape of the curved portion 31 on the front side after facing straight from the rear side to the front side. The lower side 501 is formed in a shape that descends from the rear side toward the front side and then turns up in front of the curved portion of the upper side. On the other hand, the front and rear sides 502 and 503 are formed substantially in parallel, and the front side 502 is formed in the same shape as the rear side 503 or slightly longer than the rear side 503.

The fin portion 5 is provided with a rain catcher 51 that is raised from a position in contact with the lower side of the surface 50. The rain catcher 51 is formed in a long shape along the lower side of the fin portion 5, and forms a water channel along the longitudinal direction. Since the rain catcher 51 is provided along the lower side of the fin portion 5, a part of the front side is formed so as to rise from the rear side to the front side. Further, the rain catcher 51 is formed in a shape that tapers toward the front side. Of the rain catcher 51, a portion formed in a shape that rises on the front side is particularly referred to as a riding upper portion 52.

As shown in FIG. 1, the fin portion 5 is formed with a mounting portion 61 formed in a planar shape on the front side of the back surface 60. In the first embodiment, a plurality of sleeve tiles 1 are assembled back and forth, but a part of the rear end side of the sleeve tile 1 assembled on the front side is in the front side of the sleeve tile 1 assembled on the rear side. Be assembled. At this time, the fin portion 5 of the sleeve tile 1 assembled on the front side and the fin portion 5 of the sleeve tile 1 assembled on the rear side partially overlap. Therefore, at the front end of the fin portion 5, a mounting portion 61 formed in a planar shape is formed so that the fin portion 5 of the sleeve tile 1 assembled on the front side can overlap.
Further, in the fin portion 5, the front side portion with which the mounting portion 61 abuts when the sleeve tile 1 is assembled back and forth is formed in a flat shape.

The fin portion 5 is formed with a raised portion 62 that rises from the back surface 60. The raised portion 62 is formed in a long shape from the front side to the rear side of the fin portion 5 at a position in contact with the lower side of the back surface 60, except for the portion where the mounting portion 61 is formed. The raised portion 62 has an inclined portion 63 inclined from the lower root portion 620 (lower side of the back surface 60) to the top portion 621. The inclined portion 63 is inclined diagonally upward from the root portion 620 toward the top portion 621. The inclined portion 63 forms a flat surface on the same surface as the contact portion 42 provided on the tile portion 3. The contact portion 42 and the inclined portion 63 come into surface contact with the flat plate when the sleeve tile 1 is placed flat on the flat plate with the portion where the tile portion 3 and the fin portion 5 are joined facing up.

As shown in FIG. 2C, when the fin portion 5 is viewed from below, the ridge line of the top portion 621 of the raised portion 62 is in the front-rear direction, that is, along the arrangement direction in which the sleeve tiles 1 are arranged in the front-rear direction. It is formed in a shape. Further, in the fin portion 5, the ridge line of the top 510 of the rain catcher 51, that is, the demarcation line defining the shape opposite to the side on which the top 621 of the raised portion 62 is located, moves the sleeve tile 1 back and forth. It is formed in a shape along the line-up direction.

2) Functions and characteristic effects of the sleeve tiles of the present embodiment Next, the functions of the sleeve tiles 1 of the present embodiment will be described. In the following, 2-1) how to assemble the sleeve tile 1 will be explained, and then 2-2) the functions and characteristic effects exhibited by each of the assembled sleeve tile 1 will be explained in order.

2-1) How to assemble the sleeve tile 1 As shown in FIG. 3, in the sleeve tile 1 of the present embodiment, the front end portion of the sleeve tile 1 assembled on the rear side is assembled on the front side. It is assembled so that it overlaps the rear end of the.

Specifically, as shown in FIG. 3C, the front portion of the tile portion 3 of the sleeve tile 1 assembled on the rear side covers the rear portion of the tile portion 3 of the sleeve tile 1 assembled on the front side. Then, the sleeve tile 1 assembled on the rear side is assembled on the sleeve tile 1 assembled on the front side. At this time, the contact surface 33 of the sleeve tile 1 assembled on the rear side is assembled so as to abut on the surface 30 of the sleeve tile 1 on the front side of the tail water return portion 37 and the tail groove 38. Further, the riding upper portion 52 included in the sleeve tile 1 assembled on the rear side is assembled so as to overlap the rain catcher 51 included in the sleeve tile 1 assembled on the front side. Further, although not shown, each sleeve tile 1 is assembled so that the mounting portion 61 of the sleeve tile 1 assembled on the rear side abuts on the surface 50 of the fin portion 5 of the sleeve tile 1 assembled on the front side. Is done.

As shown in FIG. 4, each sleeve tile 1 assembled in this way is in a state where the top portion 621 of the raised portion 62 hits the gable plate. Therefore, each sleeve tile 1 is installed with the fin portion 5 separated from the side surface of the house by a predetermined distance.

However, since the front side of the tile portion 3 is longer than the rear side, the fin portion 5 is installed on the roof with the front side open to the outside. The reason why the raised portion 62 is formed in a shape in which the height gradually decreases from the front side to the rear side is that when the sleeve tile 1 is laid on the roof, the fin portion 5 has the front side outward as described above. This is to match the fact that it is installed on the roof in the open state.

On the other hand, in the tile portion 3 of each sleeve tile 1, as shown in FIG. 3C, the rear end of the tile portion 3 is attached to the base of the roof, and the contact surface 33 of the sleeve tile 1 is on the front side. It is assembled so as to abut on the surface 30 of the sleeve tile 1 on the front side of the tail water return portion 37 and the tail groove 38 of the sleeve tile 1 to be assembled, and is installed on the ground under the roof. Therefore, each sleeve tile 1 is installed with the intermediate portion of the tile portion 3 floating from the base of the roof.

2-2) Functions exhibited by each sleeve tile 1 assembled and characteristic effects The functions exhibited by each sleeve tile 1 assembled as described above will be described in order below.
First, the function and characteristic effect of making it difficult for rainwater to flow into the fin portion 5 will be described.

A. When each sleeve tile 1 is assembled, the egg-bearing portion 34 has a water return portion 35 of the sleeve tile 1 assembled to the left side and is assembled to the front side as shown in FIG. 4, and is to the right of the water return portion 35. A space is formed in. This space forms an opening 350 in the head Mitsuke 32. Moreover, since the headrace 36 is formed adjacent to the water return portion 35, the opening 350 becomes a larger opening than the opening 350 formed only by the head Mitsuke 32 by combining with the space of the headrace 36. ing.

Therefore, in each sleeve tile 1, even if rainwater adheres to the head Mitsuke 32 due to surface tension and the rainwater flows to the fin portion 5 side, the rainwater reaches the opening of the egri portion 34 and opens 350 with the force of the flow. It is peeled off from the head Mitsuke 32 at the end of. Then, even if the peeled rainwater tries to go further along the head Mitsuke 32 due to its momentum, the destination is a space, so the fin part 5 of the sleeve tile 1 assembled on the front side The flow is suppressed and falls into the headrace 36, and flows down into the headrace 36 provided in the tile portion 3 of the sleeve tile 1 assembled on the front side.

Therefore, in the sleeve tile 1 of the present embodiment, even if rainwater adheres to the head portion 32 due to surface tension, it is peeled off by the egri portion 34, so that the rainwater is applied to the fin portion 5 of the sleeve tile 1 assembled on the front side. It can suppress the flow.

B. The water return portion 35 is provided on the fin portion 5 side of the headrace 36, and is raised from the surface 30 of the tile portion 3.
Therefore, even if the rainwater that has flowed toward the fin portion 5 side of the head tile 32 of the sleeve tile on the rear side has passed through the opening 350 of the egri portion 34 and still heads toward the fin portion 5, the rainwater. The water return portion 35 suppresses the flow of water to the fin portion 5. That is, in the sleeve tile 1 of the present embodiment, the egri portion 34 and the water return portion 35 doubly suppress the rainwater attached to the head Mitsuke 32 from reaching the fin portion 5.
Therefore, since the sleeve tile 1 of the present embodiment doubles suppresses the rainwater attached to the head Mitsuke 32 from reaching the fin portion 5, it is possible to more effectively suppress the flow of rainwater to the fin portion.

C. The water return portion 35 and the headrace 36 are provided on the edge portion on the fin portion side from the rear end portion to the front end portion.
Therefore, even if the rainwater peeled off from the head Mitsuke 32 flows on the tile portion 3 toward the fin portion 5 even after being peeled off, the rainwater flows to the fin portion 35 and the guide. The water channel 36 suppresses.
Therefore, by providing the water return portion 35 and the headrace 36, the sleeve tile 1 of the present embodiment can also suppress the rainwater flowing on the tile portion 3 toward the fin portion 5 from flowing to the fin portion.

D. Since the headrace 36 collects rainwater that has fallen on the roof tile portion 3, a large amount of rainwater is poured into the sleeve tile 1 on the front side. However, since the tip portion 360 of the headrace 36 is inclined toward the edge side opposite to the edge side where the fin portion 5 is provided, the sleeve tile 1 on the front side is transmitted along the headrace 36. The rainwater that has fallen to the bottom flows mainly toward the side opposite to the fin portion 5 side.
Therefore, the sleeve tile 1 of the present embodiment can prevent the rainwater from flowing to the fin portion 5 even if a large amount of rainwater flows through the headrace 36.

E. As shown in FIG. 5, the release point of the headrace 36 is located at a position opposite to the fin portion 5 side when viewed from the opening 350 of the egri portion 34.
Therefore, in the sleeve tile 1 of the present embodiment, even if a part of the rainwater discharged from the release point is attached to the head Mitsuke 32 and toward the fin portion 5 side, the rainwater is less likely to reach the egri portion 34.
Therefore, the sleeve tile 1 of the present embodiment can prevent the rainwater flowing through the headrace 36 from flowing to the fin portion 5 of the sleeve tile 1 assembled on the front side even for the head Mitsuke 32.

F. As shown in FIG. 6, the tail groove 38 allows rainwater to enter the fin portion even if rainwater intrudes into the portion of the surface of the tile portion 3 where the tile portion 3 of the sleeve tile 1 assembled on the rear side overlaps. It is sent from the edge provided with 5 to the opposite edge and ejected to the outside.
Therefore, the sleeve tile 1 of the present embodiment can prevent rainwater from staying in the portion where the tile portions 3 of the sleeve tile 1 assembled on the rear side overlap.
In this embodiment, the headrace 36 also reaches the rear end of the tile portion 3. Therefore, even if rainwater infiltrates into the portion of the surface of the roof tile portion 3 where the tile portion 3 of the sleeve tile 1 assembled on the rear side overlaps with the headrace portion 36, the fin portion 5 is provided with the invaded rainwater. It has the function of sending from the edge to the opposite edge and pushing it out.

G. As shown in FIG. 4, when the sleeve tiles 1 are combined in the front-rear direction, the water return portion 35 of the sleeve tile 1 on the front side enters the egri portion 34, and the water return portion 35 enters. It is sometimes formed in such a size that an opening is formed in the head Mitsuke 32.
Therefore, the sleeve tile 1 of the present embodiment does not need to form the recess into which the water return portion 35 enters separately from the egri portion 34, so that the structure can be simplified as compared with the case where these are formed separately.

H. Since the raised portion 62 is provided on the back surface 60 of the fin portion 5, the fin portion 5 is installed at a predetermined distance from the side surface of the house.
Therefore, the sleeve tile 1 of the present embodiment can prevent rainwater that has reached the lower end of the fin portion 5 from adhering to the gable board.

I. The raised portion 62 is formed in a long shape from the front edge portion side of the fin portion 5 toward the rear edge portion side.
Therefore, in the sleeve tile 1 of the present embodiment, even if rainwater splashes at the lower end of the fin portion 5 due to falling suitability or the like, the splashed rainwater is suppressed from reaching the gable board.

J. As shown in FIG. 1, the raised portion 62 includes an inclined portion 63 that inclines diagonally upward from the root portion 620 toward the top portion 621.
Therefore, the surface tension prevents rainwater from adhering to the raised portion 62 and heading from the root portion 620 toward the top portion 621.
Therefore, in the sleeve tile 1 of the present embodiment, not only the rainwater that has just reached the lower end of the fin portion 5, but also the rainwater that bounces off at the lower end of the fin portion 5, and the raised portion 62 is raised toward the top 621 due to surface tension. Rainwater that is about to be attached can also be suppressed from sticking to the windbreak plate.

K. As shown in FIG. 7, the contact portion 42 and the inclined portion 63 are in surface contact with each other on the same surface.
Therefore, as shown in FIG. 8, if the sleeve tile 1 is placed flat on a flat plate with the portion where the tile portion 3 and the fin portion 5 are joined face up, the sleeve tile 1 can be placed on a drying trolley or the like. Can be placed horizontally in a stable manner.
Therefore, in the production process of the sleeve tile 1, since it can be incorporated into a production line capable of mass production, the production efficiency can be significantly improved as compared with the manual factory.

L. As shown in FIG. 9, the top portion 621 of the raised portion 62 is formed in a shape along the arrangement direction of the sleeve tiles 1. Further, the top 510 of the rain catcher 51 is formed in a shape along the arrangement direction of the sleeve tiles 1. As a result, the two apex 621 and the apex 510 are substantially parallel.
Therefore, when each fin portion 5 in which a plurality of sleeve tiles 1 are assembled is viewed from below, the ridge line of the top portion 621 of the raised portion 62 included in each fin portion 5 and the top of the rain catcher 51 on the opposite side are parallel to each other. line up.
Therefore, in the sleeve tile 1 of the present embodiment, the appearance of the fin portions 5 assembled in the front and rear looking up from below is very beautiful in terms of design.

M. As shown in FIG. 3C, when a plurality of sleeve tiles 1 are assembled back and forth, the rain catcher 51 rides on the rain catcher 51 of the sleeve tile on the front side, so that the rain catcher 51 is combined. As shown in FIG. 3A, the 51 forms a long water channel from the rear sleeve tile 1 to the front sleeve tile 1.
In addition, it catches rainwater that flows down the rain catcher 51 and the fin portion 5 and falls to the lower end of the fin portion 5.
Therefore, in the sleeve tile 1 of the present embodiment, rainwater flowing through the fin portion 5 is collected and sent to the head of the rain catcher 51 to which the rainwater is connected, so that rainwater is prevented from falling from each sleeve tile 1. can. As a result, it is possible to suppress the generation of rain noise when rainwater hits the outdoor unit of the air conditioner installed below the keraba. Further, the sleeve tile 1 of the present embodiment does not pollute the so-called berm or the like by raindrops.
