Description

[Technical field]

[0001] The present invention relates to a gutter fitting and a gutter system. [Background technology]

[0002] In structures, gutters are used to drain rainwater and the like. Gutters are connected in the longitudinal direction by gutter joints. As shown in Patent Document 1, for example, an open groove is formed at the end edge of the gutter joint, and the gutter is connected in the longitudinal direction by inserting and fitting the end of the gutter into the open groove. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 6-51340 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, in the conventional gutter joint, an open groove of the same width is formed over the entire edge portion. Therefore, when the end of the gutter is inserted into the open groove, the entire end of the gutter is covered by the open groove, making it difficult to visually confirm the end of the gutter. Therefore, when connecting the end of the gutter to the gutter joint, it is difficult to confirm that the end of the gutter is securely inserted into the open groove.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a gutter joint and gutter system that allows the connection status of the gutters to be easily checked during construction to connect the gutters. [Means for solving the problem]

[0006] A gutter joint according to one embodiment of the present invention is a gutter joint that connects gutters in the longitudinal direction, and comprises a main body including a bottom portion, a front portion and a back portion arranged at both ends of the bottom portion, stopper portions provided on the inner surfaces of the front portion and the back portion, and claw portions extending from the stopper portions in the longitudinal direction of the gutter, and the claw portions have a narrowed portion. Effect of the Invention

[0007] According to the present invention, the connection state of the gutter can be easily checked. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a gutter joint and a gutter system according to one embodiment of the present invention will be described with reference to the drawings. <Gutter System> As shown in Fig. 1, the gutter system 1 comprises a first eaves gutter (first gutter, gutter) 10, a second eaves gutter (second gutter, gutter) 20, and a gutter joint 30. The first eaves gutter 10 and the second eaves gutter 20 are connected in the longitudinal direction of the eaves gutter by the gutter joint 30. Specifically, the longitudinal end 10a of the first eaves gutter 10 and the longitudinal end 20a of the second eaves gutter 20 are each inserted into and connected to the gutter joint 30. Hereinafter, the longitudinal direction of the eaves gutter may be simply referred to as the "longitudinal direction".

[0010] The first eaves gutter 10 is disposed on the first side (one side) of the gutter joint 30 in the longitudinal direction. The first eaves gutter 10 has a U-shaped cross section. The second eaves gutter 20 is disposed on the second side (the other side) of the gutter joint 30 in the longitudinal direction. The second eaves gutter 20 is a member having the same configuration as the first eaves gutter 10. The first eaves gutter 10 is connected to the first side of the gutter joint 30, whereas the second eaves gutter 20 is disposed on the second side of the gutter joint 30, which is different. Hereinafter, when there is no need to distinguish between the first eaves gutter 10 and the second eaves gutter 20, they will be referred to as eaves gutter (gutter) 10, 20. In the embodiment, an example in which an eaves gutter is connected to the gutter joint as a gutter will be described, but instead of an eaves gutter, a valley gutter may be connected to the gutter joint.

[0011] <Gutter joint> As shown in Figs. 1 to 8, the gutter joint 30 connects the first eaves gutter 10 and the second eaves gutter 20 in the longitudinal direction. The gutter joint 30 comprises a main body 31 and a connection part 32. The main body 31 houses the first eaves gutter 10 and the second eaves gutter 20 on the inner side surface of the U-shape. The main body 31 includes a back surface part (side surface part) 34, a bottom surface part 35, and a front surface part (side surface part) 36. The main body 31 has the back surface part 34, the bottom surface part 35, and the front surface part 36 connected in a U-shape.

[0012] The rear portion 34 is a portion located on the side of the wall of the structure on which the eaves gutters 10, 20 are arranged. The bottom portion 35 is a portion whose end on the wall side is connected to the lower end of the rear portion 34. The front portion 36 is a portion located on the opposite side of the rear portion 34, and whose lower end is connected to the end of the bottom portion 35 on the opposite side of the wall. In other words, the rear portion 34 and the front portion 36 are located at both ends of the bottom portion in a direction intersecting laterally (horizontally) with the longitudinal direction. The end faces (upper ends) of the rear portion 34 and the front portion 36 may be provided with ears. For example, the ears are provided to protrude from the outer surface of the rear portion 34 and the outer surface of the front portion 36. In this embodiment, the vertical dimension of the rear portion 34 is smaller than the dimension of the front portion 36. Alternatively, without being limited to this, the vertical dimensions of the rear portion 34 and the front portion 36 may be equal to each other or the front portion 36 may be smaller depending on the shape of the eaves gutters 10, 20.

[0013] Here, ribs for reinforcing the first eaves gutter 10 and the second eaves gutter 20 may be provided at the corners of the U-shaped cross section of the first eaves gutter 10 and the second eaves gutter 20. In this case, a rib receiver 37 may be provided at the corners of the U-shaped cross section of the gutter joint 30 corresponding to the rib. The rib receiver 37 is connected to a claw portion 42 described later and protrudes inward from the main body portion 31. The rib receiver 37 is formed, for example, with the same width as the claw portion 42. For example, ribs 10b, 20b provided on the bottom surfaces of the first eaves gutter 10 and the second eaves gutter 20 are fitted into the rib receiver 37. The ribs 10b, 20b may be hollow protrusions provided at the connection positions between the bottom surfaces and side surfaces of the eaves gutter 10, 20.

[0014] Furthermore, ears may be provided at the upper end of the U-shaped cross section of the first eaves gutter 10 and the second eaves gutter 20 to reinforce the first eaves gutter 10 and the second eaves gutter 20. In this case, ear hooks 38 may be provided at the upper end of the U-shaped cross section of the gutter joint 30 to correspond to the ears. The ear hooks 38 protrude from the upper side of the gutter joint 30 toward the inside of the main body 31. The ear hooks 38 are formed to have the same width as, for example, claws 42 described below.

[0015] The connection part 32 connects the first eaves gutter 10 located on the first side in the longitudinal direction to the second eaves gutter 20 located on the second side. The connection part 32 is formed along the U-shaped inner side surface of the main body part 31. The connection part 32 includes a stopper part 41 and a claw part 42. The stopper portion 41 is a portion against which the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 abut. The stopper portion 41 is formed so as to protrude inwardly of the U-shape from the main body portion 31. That is, the stopper portion 41 is provided on the inner surface of the bottom portion 35, the inner surface of the back portion 34, and the inner surface of the front portion 36.

[0016] The stopper portion 41 has a first stopper 45, a second stopper 46, and a third stopper 47. The first stopper 45 is provided on the inner surface of the back portion 34. The first stopper 45 protrudes from the inner surface of the back portion 34 toward the inside of the main body portion 31. The second stopper 46 is provided on the inner surface of the bottom portion 35. The second stopper 46 protrudes from the inner surface of the bottom portion 35 toward the inside of the main body portion 31. The third stopper 47 is provided on the inner surface of the front portion 36. The third stopper 47 protrudes from the inner surface of the front portion 36 toward the inside of the main body portion 31. The first stopper 45, the second stopper 46, and the third stopper 47 are provided with claw portions 42.

[0017] The claw portion 42 projects from the stopper portion 41 toward the first side and the second side. The end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 are inserted between the claw portion 42 and the main body portion 31. The claw portion 42 includes a claw portion 42A provided on the first stopper 45, a claw portion 42B provided on the second stopper 46, and a claw portion 42C provided on the third stopper 47. Hereinafter, the claw portion 42A provided on the first stopper 45 will be described in detail, and detailed descriptions of the claw portion 42B provided on the second stopper 46 and the claw portion 42C provided on the second stopper 46 will be omitted.

[0018] The claw portion 42A has a first claw portion 51, a constricted portion 52, and a second claw portion 53. The first claw portion 51 extends downward from the upper side of the back surface portion 34 toward the bottom surface portion 35 to a portion of the back surface portion 34. The constricted portion 52 extends downward from the lower end of the first claw portion 51 toward the bottom surface portion 35 to a portion of the back surface portion 34. The second claw portion 53 extends downward from the lower end of the constricted portion 52 to the bottom surface portion 35. That is, the constricted portion 52 is provided midway between the first claw portion 51 and the second claw portion 53 in the up-down direction. Also, the claw portion 42A is divided into two, the first claw portion 51 and the second claw portion 53, in the up-down direction by the constricted portion 52. In the embodiment, an example in which the claw portion 42A is divided into two, the first claw portion 51 and the second claw portion 53, will be described, but the claw portion 42A may be divided into three or more portions. The first claw portion 51, the constricted portion 52, and the second claw portion 53 will be described in detail below.

[0019] The first claw portion 51 protrudes from the first stopper 45 toward the first side and the second side in the longitudinal direction. That is, the first claw portion 51 is held by the first stopper 45. The first claw portion 51 has a first claw piece 51a and a second claw piece 51b. The first claw piece 51a protrudes from the first stopper 45 toward the first side in the longitudinal direction. The second claw piece 51b protrudes from the first stopper 45 toward the second side in the longitudinal direction. The first claw piece 51a and the second claw piece 51b have the same width in the longitudinal direction (protruding width). The widths of the first claw piece 51a and the second claw piece 51b do not have to be the same.

[0020] As shown in Figs. 9 and 10, the first fitting portion 55 is formed by the first claw piece 51a, the first stopper 45, and the inner surface of the back surface portion 34. The first fitting portion 55 is formed to have a U-shaped cross section. The first fitting portion 55 has an opening at the end on the first side in the longitudinal direction. The end 10a of the first eaves gutter 10 is inserted from the opening of the first fitting portion 55. In other words, the end 10a of the first eaves gutter 10 is inserted between the first claw piece 51a and the back surface portion 34. The end 10a of the first eaves gutter 10 contacts the first stopper 45 by being inserted into the first fitting portion 55. The end 10a of the first eaves gutter 10 is positioned at the insertion position by contacting the first stopper 45.

[0021] Further, the second claw piece 51b, the first stopper 45, and the inner surface of the back surface portion 34 form a second fitting portion 56. The second fitting portion 56 is formed to have a U-shaped cross section. The second fitting portion 56 has an opening at the second end portion in the longitudinal direction. The end portion 20a of the second eaves gutter 20 is inserted from the opening of the second fitting portion 56. In other words, the end portion 20a of the second eaves gutter 20 is inserted between the second claw piece 51b and the back surface portion 34. The end portion 20a of the second eaves gutter 20 is inserted into the second fitting portion 56 and comes into contact with the first stopper 45. The end portion 20a of the second eaves gutter 20 is positioned at the insertion position by coming into contact with the first stopper 45.

[0022] Returning to FIG. 1 to FIG. 8, the second claw portion 53 is formed in the same manner as the first claw portion 51. That is, the second claw portion 53 has a first claw piece 53a and a second claw piece 53b. The first claw piece 53a protrudes from the first stopper 45 to the first side in the longitudinal direction. The second claw piece 53b protrudes from the first stopper 45 to the second side in the longitudinal direction. The first claw piece 53a and the second claw piece 53b have the same width in the longitudinal direction (protruding width). Note that the widths of the first claw piece 53a and the second claw piece 53b do not have to be the same.

[0023] The first claw 51a and the first claw 53a have the same width in the longitudinal direction (projection width). The second claw 51b and the second claw 53b have the same width in the longitudinal direction (projection width). In the embodiment, the width of the first claw 51a and the first claw 53a is 25 mm, and the width of the second claw 51b and the second claw 53b is 25 mm, but is not limited thereto. Hereinafter, the width of the first claw 51a and the second claw 51b may be referred to as the width of the first claw portion 51, and the width of the first claw 53a and the second claw 53b may be referred to as the width of the second claw portion 53. The widths of the first claw pieces 51a and 53a do not have to be the same, and the widths of the second claw pieces 51b and 53b do not have to be the same.

[0024] Further, a third fitting portion 57 is formed by the first claw piece 53a, the first stopper 45, and the inner surface of the back surface portion 34. The third fitting portion 57 is formed in the same manner as the first fitting portion 55. Further, a fourth fitting portion 58 is formed by the second claw piece 53b, the first stopper 45, and the inner surface of the back surface portion 34. The fourth fitting portion 58 is formed in the same manner as the second fitting portion 56.

[0025] 1, 9 and 10, the constricted portion 52 is formed only by the first stopper 45 excluding the first claw portion 51 and the second claw portion 53. The constricted portion 52 is formed, for example, in a rectangular cross section. In the embodiment, an example in which the constricted portion 52 is formed in a rectangular cross section will be described, but the cross section of the constricted portion 52 may be formed in a curved shape. Specifically, the constricted portion 52 is formed with a longitudinal width of 0 mm when the width of the first claw portion 51 and the second claw portion 53 is 25 mm, for example. That is, the constricted portion 52 is 0% of the longitudinal width of the claw portion 42A. The protrusion amount of the constricted portion 52 from the back surface portion 34 is flush with the plate thickness of the end portion 10a of the first eaves gutter 10 and the plate thickness of the end portion 20a of the second eaves gutter 20. Therefore, the smoothness of the constricted portion 52, the end portion 10a of the first eaves gutter 10, and the end portion 20a of the second eaves gutter 20 can be maintained. This allows rainwater to flow smoothly inside the gutter joint 30, and ensures the drainage of the gutter system 1.

[0026] Here, for example, if the constricted portion 52 protrudes from the end 10a of the first eaves gutter 10 and the end 20a of the second eaves gutter 20 toward the inside of the main body 31, the resistance of the constricted portion 52 to rainwater flowing through the gutter joint 30 will be large. In contrast, for example, if the constricted portion 52 is not protruded from the end 10a of the first eaves gutter 10 and the end 20a of the second eaves gutter 20, the resistance of the constricted portion 52 to rainwater flowing through the gutter joint 30 can be kept small.

[0027] In the embodiment, an example will be described in which the constricted portion 52 is formed only by the first stopper 45, excluding the first claw portion 51 and the second claw portion 53, but this is not limited to the above. As another example, a first overhanging piece may overhang from the first stopper 45 to the first side, and a second overhanging piece may overhang from the first stopper 45 to the second side. The first overhanging piece is preferably 30% or more smaller than the longitudinal overhang width of the first claw piece 51a of the first claw portion 51 and the first claw piece 53a of the second claw portion 53, more preferably 50% or more smaller, even more preferably 60% or more smaller, and even more preferably 70% or more smaller. Furthermore, it is preferable that the second protrusion piece is 30% or more smaller than the longitudinal protrusion width of the second claw piece 51b of the first claw portion 51 and the second claw piece 53b of the second claw portion 53, more preferably 50% or more smaller, even more preferably 60% or more smaller, and even more preferably 70% or more smaller. That is, the width of the constricted portion 52 is preferably 0% to 70% of the longitudinal width of the first claw portion 51 and the second claw portion 53, more preferably 50% or less, even more preferably 40% or less, and even more preferably 30% or less. The reason for setting the width of the constricted portion 52 to 0% to 70% of the width of the first claw portion 51 and the second claw portion 53 will be explained in detail later.

[0028] Here, claw portion 42B provided on second stopper 46 is formed similarly to claw portion 42A provided on first stopper 45. Claw portion 42C provided on third stopper 47 is also formed similarly to claw portion 42A provided on first stopper 45. In the illustrated example, first stopper 45 provided on back surface portion 34 is also provided with constricted portion 52, and third stopper 47 provided on front surface portion 36 is also provided with constricted portion 52. In addition, the height (vertical position) of the constriction 52 of the rear portion 34 and the constriction 52 of the front portion 36 may be the same, and the constriction 52 of the rear portion 34 may be located above or below the constriction 52 of the front portion 36. For example, when the height (position of the upper end) of the front portion 36 is different from the height (position of the upper end) of the back portion 34, the height of the constricted portion 52 of the back portion 34 may be different from the height of the constricted portion 52 of the front portion 36. For example, the constricted portion 52 provided on the higher of the front portion 36 and the back portion 34 may be located higher or lower than the constricted portion 52 provided on the lower of the front portion 36. For example, when the front portion 36 is higher than the back portion 34 (high front gutter), the height of the constricted portion 52 of the front portion 36 may be higher than the height of the constricted portion 52 of the back portion 34. Here, the height of the constricted portion 52 may be the vertical distance from the upper surface of the bottom portion 35 to the lower end of the constricted portion 52. For example, if the narrowed portion 52 is provided on the end face side (upper end side, ear side) of the side portion (front portion 36, back portion 34), it will be easier to see even when the first eaves gutter 10 and the second eaves gutter 20 are inserted at an angle, as described below.

[0029] <How to install the gutter system> Next, a construction method for connecting the first eaves gutter 10 and the second eaves gutter 20 to the gutter joint 30 in the gutter system 1 will be described with reference to Figs. 1, the rear portion 34 is disposed on the side of the wall surface (i.e., the rear side) of the structure on which the eaves gutters 10, 20 are disposed. Therefore, the rear portion 34 is disposed in a position where the connection portion 32 is more easily visible than the front portion 36, etc., during construction to connect the first eaves gutter 10 and the second eaves gutter 20 to the gutter joint 30. Therefore, only the claw portion 42A provided on the first stopper 45 of the rear portion 34 will be described, and detailed descriptions of the claw portion 42B provided on the second stopper 46 and the claw portion 42C provided on the third stopper 47 will be omitted.

[0030] As shown in FIG. 11, the second eaves gutter 20 is grasped with one hand 60, and the claw portion 42 and the main body portion 31 of the gutter joint 30 are fitted to the end portion 20a of the second eaves gutter 20. Thus, the connection portion 32 of the gutter joint 30 is connected to the end portion 20a of the second eaves gutter 20. At this time, the second fitting portion 56 is fitted to the end portion 20a of the second eaves gutter 20 from the opening, and the first stopper 45 comes into contact with the end portion 20a of the second eaves gutter 20. The state in which the first stopper 45 is in contact with the end portion 20a of the second eaves gutter 20 can be visually confirmed by the constricted portion 52. At this time, the other hand 62 may grasp the gutter joint 30.

[0031] As shown in FIG. 12, the first eaves gutter 10 is grasped with the other hand 62, and the end 10a of the first eaves gutter 10 is inserted between the claw portion 42 and the back portion 34 of the gutter joint 30. Thus, the end 10a of the first eaves gutter 10 is connected to the connection portion 32 of the gutter joint 30. At this time, the end 10a of the first eaves gutter 10 is inserted from the opening into the first fitting portion 55 and contacts the first stopper 45. The state in which the end 10a of the first eaves gutter 10 is in contact with the first stopper 45 can be visually confirmed by the constricted portion 52. As a result, it can be visually confirmed by the constricted portion 52 that the first eaves gutter 10 and the second eaves gutter 20 are connected to the connection portion 32 of the gutter joint 30 with the first stopper 45 positioned at the insertion position.

[0032] 13, for example, there may be a case where the end 10a of the first eaves gutter 10 is not fully inserted from the opening to the back of the first fitting portion 55. At this time, it is possible to visually confirm from the constricted portion 52 that the end 10a of the first eaves gutter 10 is not in contact with the first stopper 45. In this case, the end 10a of the first eaves gutter 10 can be brought into contact with the first stopper 45 by pushing the end 10a of the first eaves gutter 10 until it comes into contact with the first stopper 45.

[0033] 14, for example, it is possible to insert the end 10a of the first eaves gutter 10 between the claw portion 42 and the main body portion 31 of the gutter joint 30 with the first eaves gutter 10 tilted upward in the longitudinal direction. At this time, it is possible to visually confirm from the constricted portion 52 that the end 10a of the first eaves gutter 10 is inserted obliquely into the first stopper 45. In this case, the arrangement of the first eaves gutter 10 can be corrected in the longitudinal direction so that the end 10a of the first eaves gutter 10 can be inserted between the claw portion 42 and the main body portion 31 of the gutter joint 30. Alternatively, for example, the end 10a of the first eaves gutter 10 may be cut at an angle. In this case, too, it is possible to visually confirm from the constricted portion 52 that the end 10a of the first eaves gutter 10 is cut at an angle.

[0034] As shown in Fig. 15, after connecting the end 10a of the first eaves gutter 10 and the end 20a of the second eaves gutter 20 to the connection part 32 of the gutter joint 30, a string-like sealing treatment is performed all around along the claw part 42 so as to leave no gaps. That is, adhesive 65 is filled so as to fill the gap between the end 10a of the first eaves gutter 10 and the claw part 42. Also, adhesive 65 is filled so as to fill the gap between the end 20a of the second eaves gutter 20 and the claw part 42. This completes the construction method for connecting the first eaves gutter 10 and the second eaves gutter 20 to the gutter joint 30 and assembling the gutter system 1. Note that the construction order of the first eaves gutter 10 and the second eaves gutter 20 may be reversed, and furthermore, both eaves gutters 10, 20 may be constructed simultaneously.

[0035] According to the gutter joint 30 and gutter system 1 of the embodiment described above, as shown in Fig. 1 and Fig. 12, the claw portion 42A has a constricted portion 52. Therefore, when the first eaves gutter 10 and the second eaves gutter 20 are connected to the gutter joint 30, the end portion 10a of the first eaves gutter 10 inserted into the first fitting portion 55 of the gutter joint 30 can be visually confirmed from the constricted portion 52. Also, the end portion 20a of the second eaves gutter 20 inserted into the second fitting portion 56 of the gutter joint 30 can be visually confirmed from the constricted portion 52. This makes it easy to check the connection state of the first eaves gutter 10 and the second eaves gutter 20 in the gutter joint 30 when the first eaves gutter 10 and the second eaves gutter 20 are connected.

[0036] In particular, as shown in Fig. 14, when connecting the end 10a of the first eaves gutter 10 to the gutter joint 30, for example, the first eaves gutter 10 may be inserted between the claw portion 42 and the main body portion 31 of the gutter joint 30 with the end 10a inclined upward with respect to the longitudinal direction. In this case, it is easy to see from the constricted portion 52 that the end 10a of the first eaves gutter 10 is inserted at an angle into the first stopper 45. This allows the first eaves gutter 10 to be inserted substantially straight along the longitudinal direction by pushing in the end 10a of the first eaves gutter 10 while visually checking the constricted portion 52.

[0037] 1 and 10 is injection molded from, for example, a resin material. For this reason, when the claw portion 42A of the back surface portion 34 is long in a direction intersecting the longitudinal direction (i.e., the up-down direction), when the gutter joint 30 is injection molded, it is considered that the claw portion 42A will be inclined toward the back surface portion 34 as it moves from the first stopper 45 to the longitudinal side edge. In this case, the opening between the claw portion 42A and the back surface portion 34 becomes narrow. For this reason, it becomes difficult to insert the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 between the claw portion 42A and the back surface portion 34.

[0038] Therefore, the claw portion 42A has a constricted portion 52, and the claw portion 42A is divided into two in the vertical direction. Therefore, the first claw portion 51 and the second claw portion 53 can be shortened in the vertical direction. This makes it possible to prevent the first claw piece 51a and the second claw piece 51b of the first claw portion 51 from inclining toward the back surface portion 34 when the gutter joint 30 is injection molded. Also, it makes it possible to prevent the first claw piece 53a and the second claw piece 53b of the second claw portion 53 from inclining toward the back surface portion 34. Therefore, the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 can be easily inserted between the claw portion 42A and the back surface portion 34.

[0039] 1, 9, and 10, the reason for setting the width of the constricted portion 52 to 0% to 70% of the width of the first claw portion 51 and the second claw portion 53 will be described in detail. That is, by setting the width of the constricted portion to 0 mm, for example, the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 inserted between the claw portion 42A of the gutter joint 30 and the back surface portion 34 can be easily seen from the constricted portion 52. Therefore, the width of the constricted portion 52 is set to 0% or more of the width of the first claw portion 51 and the second claw portion 53.

[0040] On the other hand, for example, if the width of the constricted portion 52 exceeds 70% of the width of the first claw portion 51 and the second claw portion 53, it is difficult to visually confirm the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 inserted between the claw portion 42A of the gutter joint 30 and the back surface portion 34 from the constricted portion 52. Therefore, the width of the constricted portion 52 is set to 70% or less of the width of the first claw portion 51 and the second claw portion 53. In this way, the width of the constricted portion 52 is set to 0% to 70% of the width of the first claw portion 51 and the second claw portion 53. This makes it possible to easily see the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 inserted between the claw portion 42A of the gutter joint 30 and the back surface portion 34 from the constricted portion 52.

[0041] Furthermore, even if the width of the constriction portion 52 is set to 0% relative to the width of the first claw portion 51 and the second claw portion 53, the first stopper 45 can prevent interference between the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20.

[0042] 1, the constricted portion 52 is provided midway through the claw portion 42A, dividing the claw portion 42A in the vertical direction into two, a first claw portion 51 and a second claw portion 53. This makes it possible to position the constricted portion 52 at a position where the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 inserted between the claw portion 42A and the back surface portion 34 of the gutter joint 30 can be easily seen. Furthermore, by dividing the claw portion 42A into two, the first claw portion 51 and the second claw portion 53, the length of the claw portion 42A in the height direction can be shortened, for example, even when the first eaves gutter 10, the second eaves gutter 20, and the gutter joint 30 are large. Therefore, for example, when a large gutter joint 30 is injection molded, the claw portion 42A can be prevented from inclining toward the back surface portion 34. This allows the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 to be easily inserted from the opening between the claw portion 42A and the back surface portion 34.

[0043] 1, 9, and 10, the widths (overhanging widths) of the first claw piece 51a and the second claw piece 51b of the first claw portion 51 that overhang in the longitudinal direction are made the same. This allows the first claw piece 51a and the second claw piece 51b to be molded uniformly, for example, when injection molding the gutter joint. Also, the widths (overhanging widths) of the first claw piece 53a and the second claw piece 53b of the second claw portion 53 that overhang in the longitudinal direction are made the same. This allows the first claw piece 53a and the second claw piece 53b to be molded uniformly, for example, when injection molding the gutter joint.

[0044] In addition, the first claw piece 51a and the first claw piece 53a have the same longitudinal width. Furthermore, the second claw piece 51b and the second claw piece 53b have the same longitudinal width. This allows the first claw piece 51a and the second claw piece 51b to be molded more uniformly, for example, when injection molding the gutter joint, and allows the first claw piece 53a and the second claw piece 53b to be molded more uniformly.

[0045] Furthermore, the first eaves gutter 10 and the second eaves gutter 20 can be connected by the gutter joint 30. The gutter joint 30 has a narrowed portion 52. This makes it easy to connect the first eaves gutter 10 and the second eaves gutter 20 to the gutter joint 30.

[0046] Next, a gutter joint according to a modification of the embodiment will be described with reference to Figures 16 to 22. In the gutter joint according to the modification, members that are the same as or similar to the gutter joint 30 of the embodiment will be given the same reference numerals and detailed description thereof will be omitted.

[0047] First, an example in which the claw portion is divided into three or more portions in Modification 1 of FIG. 16 and Modification 2 of FIG. 17 will be described. As shown in Fig. 16, a gutter joint 100 of the first modification is obtained by replacing the claw portion 42A of the embodiment with a claw portion 102. The claw portion 102 is divided into four portions, a first claw portion 103a to a fourth claw portion 103d, as an example of a claw portion divided into three or more portions. A first constriction 104a is provided between the first claw 103a and the second claw 103b. A second constriction 104b is provided between the second claw 103b and the third claw 103c. A third constriction 104c is provided between the third claw 103c and the fourth claw 103d.

[0048] In the illustrated example, the first claw portion 103a to the fourth claw portion 103d have different lengths in the vertical direction. Specifically, the first claw portion 103a and the fourth claw portion 103d located at the ends in the vertical direction are shorter than the second claw portion 103b and the third claw portion 103c. However, this is not limited to the above.

[0049] 17, a gutter joint 110 of the second modification is obtained by replacing the claw portion 42A of the embodiment with a claw portion 112. The claw portion 112 is divided into three portions, a first claw portion 113a to a third claw portion 113c, as an example of a claw portion divided into three or more portions. A first constricted portion 114a is provided between the first claw portion 113a and the second claw portion 113b. A second constricted portion 114b is provided between the second claw portion 113b and the third claw portion 113c.

[0050] In the illustrated example, the first claw portion 113a to the third claw portion 113c have different lengths in the up-down direction. Specifically, the length becomes shorter from the first claw portion 113a to the third claw portion 113c. However, this is not limited to the above.

[0051] Next, an example in which a first protruding piece and a second protruding piece are provided on the narrowed portion in the third modification of FIG. 18 will be described. As shown in Fig. 18, a gutter joint 120 of the third modified example has a claw portion 122 instead of the claw portion 42A of the embodiment. The claw portion 122 has a constricted portion 123 instead of the constricted portion 52 of the embodiment. The constricted portion 123 has a first stopper 45, a first protruding piece 124, and a second protruding piece 125. The first protruding piece 124 protrudes from the first stopper 45 to the first side. The second protruding piece 125 protrudes from the first stopper 45 to the second side.

[0052] Here, the first overhanging piece 124 is preferably 30% or more smaller than the overhang width on the first side of the first claw portion 51. Also, the second overhanging piece 125 is preferably 30% or more smaller than the overhang width on the second side of the first claw portion 51. This makes it possible to easily view the end 10a of the first eaves gutter 10 and the end 20a of the second eaves gutter 20 (both see FIG. 1 ) inserted between the claw portion 122 of the gutter joint 120 and the back surface portion 34 from the constricted portion 123.

[0053] Moreover, the claw portion 122 is divided into two, the first claw portion 51 and the second claw portion 53, by the constriction portion 123. Therefore, the first claw portion 51 and the second claw portion 53 can be shortened in the vertical direction. This makes it possible to prevent the first claw portion 51 and the second claw portion 53 from inclining toward the back surface portion 34 when the gutter joint 120 is injection molded. Therefore, the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 (both see embodiment 1) can be easily inserted between the claw portion 122 and the back surface portion 34.

[0054] In addition, according to the constricted portion 123 of the modified example 3, when the protruding width of the first claw portion 51 is 30 mm, for example, it is possible to form the width of the first protruding piece 124 and the second protruding piece 125 to be 15 mm. In other words, according to the constricted portion 123 of the modified example 3, it is also possible to make the width of the first protruding piece 124 and the second protruding piece 125 50% smaller than the protruding width of the first claw portion 51. In this case, for example, the first overhanging piece 124 and the second overhanging piece 125 can be used to hide the gap. That is, even if the end 10a of the first eaves gutter 10 and the end 20a of the second eaves gutter 20 inserted between the claw portion 122 of the gutter joint 120 and the back surface portion 34 are not inserted all the way into the constricted portion 123, the first overhanging piece 124 and the second overhanging piece 125 can hide the gap.

[0055] Furthermore, according to the constricted portion 123 of the third modification, for example, when the protruding width of the first claw portion 51 is 45 mm, it is also possible to form the width of the first protruding piece 124 and the second protruding piece 125 to be 30 mm. That is, according to the constricted portion 123 of the third modification, it is also possible to make the width of the first protruding piece 124 and the second protruding piece 125 30% smaller than the protruding width of the first claw portion 51. In this case, for example, as shown in Fig. 19, the first overhanging piece 124 can be used to hide the diagonal cut at the edge 10b of the first eaves gutter 10. That is, for example, the edge 10b of the first eaves gutter 10 can be cut diagonally so that it slopes from above to below toward the first side. In this case, the diagonal cut edge 10b can be hidden by the first overhanging piece 124.

[0056] Next, the projection of the first and second claw portions in the fourth modified example of FIG. 20 will be described. 20, a gutter joint 130 of the fourth modified example is obtained by replacing the claw portion 42A of the embodiment with a claw portion 132. The claw portion 132 has a first claw portion 133, a constricted portion 134, and a second claw portion 135. The second claw portion 135 gradually protrudes more toward the first side and the second side as it moves upward from the bottom surface portion 35 to the constricted portion 134. The first claw portion 133 protrudes more toward the first side and the second side in accordance with the protrusion of the upper portion of the second claw portion 135. In other words, the second claw portion 135 and the first claw portion 133 do not protrude to the same extent. In the illustrated example, the first claw portion 133 protrudes more than the second claw portion 135.

[0057] Moreover, the claw portion 132 is divided into two, a first claw portion 133 and a second claw portion 135, by the constricted portion 134. Therefore, the first claw portion 133 and the second claw portion 135 can be shortened in the vertical direction. This makes it possible to prevent the first claw portion 133 and the second claw portion 135 from inclining toward the back surface portion 34 when the gutter joint 130 is injection molded. Therefore, the end portion 10a of the first eaves gutter 10 and the end portion 20a of the second eaves gutter 20 (both see embodiment 1) can be easily inserted between the claw portion 132 and the back surface portion 34. The reason why the first claw portion 133 is extended significantly toward the first side and the second side will be described in detail with reference to FIG.

[0058] Next, an example in which a first eaves gutter is connected to the gutter joint of the embodiment and an example in which a first eaves gutter is connected to the gutter joint of Modification 4 will be described with reference to Figs. 20, 21 and 22. FIG. 21 shows a gutter joint 30 according to an embodiment. When connecting the end 10a of the first eaves gutter 10 to this gutter joint 30, the back surface 34 side of the gutter joint 30 is easily visible. Therefore, it is easier to connect the end 10a of the first eaves gutter 10 in order from the visible back surface 34 side. Also, when connecting the end 10a of the first eaves gutter 10 from the back surface 34 side of the gutter joint 30, it is easier to connect the end 10a of the first eaves gutter 10 from the first claw portion 51 arranged on the upper side of the back surface 34. Therefore, if the first claw portion 51 is protruded slightly, it becomes difficult to connect the end 10a of the first eaves gutter 10 to the first claw portion 51.

[0059] Fig. 22 shows the gutter joint 130 in the modified example 4 of Fig. 20. As shown in Figs. 20 and 22, in the gutter joint 130 in the modified example 4, the first claw portion 133 of the claw portion 132 protrudes more to the first side and the second side than, for example, the second claw portion 135 or the first claw portion 51 of the embodiment. The first claw portion 133 is disposed on the upper side of the back surface portion 34. This makes it possible to easily connect the end portion 10a of the first eaves gutter 10 to the first claw portion 133 when connecting the end portion 10a of the first eaves gutter 10 from the first claw portion 133 in the gutter joint 130.

[0060] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0061] In addition, the components in this embodiment can be replaced with well-known components as appropriate without departing from the spirit of the present invention.

[0062] (Additional Note) <1> A gutter joint according to one embodiment of the present invention is a gutter joint that connects gutters in the longitudinal direction, and comprises a main body including a bottom portion, a front portion and a back portion arranged at both ends of the bottom portion, stopper portions provided on the inner surfaces of the front portion and the back portion, and claw portions extending from the stopper portions in the longitudinal direction of the gutter, and the claw portions have a narrowed portion.

[0063] <2> the above <1> In the gutter joint according to the above, a longitudinal width of the constricted portion may be smaller than a longitudinal width of the claw portion.

[0064] According to the gutter joint, the claw portion has a constricted portion. Therefore, when connecting the gutter to the gutter joint, the gutter inserted between the claw portion and the front portion or side portion (hereinafter also referred to as the side portion) of the gutter joint can be visually confirmed from the constricted portion. This makes it easy to check the connection state of the gutter in the gutter joint when connecting the gutter.

[0065] In particular, when connecting a gutter to a gutter joint, for example, the gutter may be inserted between the claw portion and the side portion of the gutter joint while tilting it upward with respect to the longitudinal direction. In this case, it is easy to see from the constricted portion that the eaves are inserted at an angle to the stopper portion. This allows the gutter to be inserted substantially straight along the longitudinal direction by pushing it in while visually checking the constricted portion.

[0066] Also, for example, the gutter joint is injection molded with a resin material. Therefore, when the claw portion is long in the direction intersecting the longitudinal direction (i.e., the up-down direction), it is considered that the claw portion will be inclined toward the side portion as it moves from the stopper portion toward the side edge during injection molding of the gutter joint. In this case, the opening between the claw portion and the side portion becomes narrow. Therefore, it becomes difficult to insert the gutter through the opening between the claw portion and the side portion. Therefore, the claw portion has a constriction to shorten the claw portion in the vertical direction. This prevents the claw portion from tilting toward the side portion during injection molding of the gutter joint. This makes it easy to insert the gutter through the opening between the claw portion and the side portion.

[0067] <3> the above <1> or <2> In the gutter joint according to the present invention, the constricted portion may be provided midway through the claw portion, and the claw portion may be divided into a plurality of portions.

[0068] In this way, the constricted portion is provided midway through the claw portion to divide the claw portion into multiple portions, which makes it possible to position the constricted portion at a position where the gutter inserted between the claw portion and the side portion of the gutter joint can be easily seen. In addition, by dividing the claw portion into multiple portions, the length of the claw portion can be shortened, even when the gutter and gutter joint are large. Therefore, for example, when a large gutter joint is injection molded, the claw portion can be prevented from tilting toward the side portion. This makes it easy to insert the gutter through the opening between the claw portion and the side portion.

[0069] <4> the above <3> In the gutter joint according to the present invention, the plurality of divided claw portions may be arranged at equal intervals.

[0070] In this way, by arranging the multiple divided claw portions at equal intervals, the multiple divided claw portions can be molded uniformly, for example, when injection molding the gutter joint.

[0071] <5> the above <1> In the gutter joint relating to the above, the claw portion has a first claw piece extending from the stopper portion to one side in the longitudinal direction, and a second claw piece extending to the other side, and the first claw piece and the second claw piece may have the same longitudinal width.

[0072] In this way, by making the widths of the first claw piece and the second claw piece the same, the first claw piece and the second claw piece can be molded uniformly, for example, when the gutter joint is injection molded.

[0073] <6> In one aspect of the present invention, the gutter system includes a first gutter arranged on a first side in the longitudinal direction and a second gutter arranged on a second side, and the first gutter and the second gutter are <1> From the above <5> The connection is made by a gutter joint according to any one of claims 1 to 5.

[0074] According to the gutter system, the first gutter and the second gutter are connected by the gutter joint of the present invention, which makes it easy to perform construction work for connecting the first gutter and the second gutter to the gutter joint. [Explanation of symbols]
