The inner diameter of the ring portion 14 is substantially equal to the outer diameter of the insertion port 13, and the outer diameter of the ring portion 14 is equal to the outer diameter of a portion of the bending portion 12 extending in the direction of the arrow D2. Therefore, as shown in FIG. 3, when the ring portion 14 is externally fitted to the insertion port 13, the outer peripheral surface of the curved portion 12 and the outer peripheral surface 14R of the ring portion 14 become flush.
Further, the ring portion 14 is formed to have a size that allows the insertion port 13 to pass through and allows the insertion port 13 to be protruded in the direction of the arrow D2. That is, the length dimension of the ring portion 14 in the direction of the axis J 14 is smaller than the length dimension of the insertion port 13.

An engaging portion 18 is provided on the outer peripheral surface 14R of the ring portion 14.
The engaging portion 18 is a projection that protrudes in the radial direction of the ring portion 14 from the outer peripheral surface 14 </ b> R of the ring portion 14. Further, although the engaging portions 18 are provided at mutually opposite positions centering on the axis line J14 when the ring portion 14 is viewed in plan, the number of the engaging portions 18 and the length in the circumferential direction are particularly It is not limited.

  The length dimension of the short pipe 16 in the direction of the axis J16 is larger than the length dimension of the insertion port 13 of the curved portion 12 protruding from the ring portion 14. The outer peripheral surface C of the insertion port 13 of the curved portion 12 protruding from the ring portion 14 and the inner peripheral surface D of the upper end portion of the short tube 16 are bonded by an adhesive or the like. Thereby, the short tube 16 is non-rotatably connected to the bending portion 12.

  The joint rod 20 is cylindrically formed of a synthetic resin such as vinyl chloride. Further, the fitting rod 20 is a bottomed cylindrical tubular body 26 into which the elbow 10 is inserted, a tubular body 28 to which the upper weir 5a and the lower weir 5b are connected, and the tubular body 26 and the tubular body 28 A connecting portion 29 is provided to connect the cylindrical body 26 and the tubular body 28 in a state in which the directions of the axis lines J26 and J28 are vertically oriented and adjacent to each other.

  The cylindrical body 26 has a peripheral wall 26a whose lower end is obliquely cut with respect to the axis J26, and a flat bottom 26b which is inclined toward the lower side of the pipe 28 in accordance with the lower end face of the peripheral wall 26a. Have.

  An engaged portion 24 is formed on the upper portion of the peripheral wall portion 26a. The circumferential wall portion 26a is devoid of a part in the circumferential direction continuously in the direction of the axis J26, and is formed in a substantially C shape when viewed in the direction of the axis J26. The portion devoid of the peripheral wall portion 26a constitutes an opening 40 opened toward the tube 28, and is formed at least from the axially middle portion (from the upper end in the present embodiment) to the bottom portion 26b located at the lowermost end ing.

  With this configuration, when the short pipe 16 is inserted until the engagement portion 18 of the ring portion 14 engages with the engaged portion 24 of the cylindrical body 26, the opening 40 of the cylindrical body 26 below the short pipe 16 It opens toward the 28 inner holes H2.

The tubular body 28 has the upper collar 5a internally fitted in the inner hole H2 and penetrates from the lower end in the direction of the axis J28 which is internally fitted with the lower collar 5b at a distance from the upper collar 5a. A part in the circumferential direction of the peripheral wall portion 28a forming the tube body 28 is continuously omitted in the direction of the axis J28, and is formed in a substantially reverse C shape when viewed in the direction of the axis J28. The portion devoid of the peripheral wall portion 28a constitutes an opening 41 opened toward the cylindrical body 26 and is formed at least to a position corresponding to the lowermost end of the bottom portion 26b in the axial direction middle portion (from the upper end in this embodiment) It is done.
The opening 40 of the cylindrical body 26 and the opening 41 of the pipe 28 are disposed to face each other. The openings 40 and 41 are formed to have the same width when the cylindrical body 26 and the tubular body 28 are projected and viewed from the direction orthogonal to both the axis lines J26 and J28.

  The connection portion 29 is a connection piece 29a for connecting the side ends 30, 30 of the peripheral wall portion forming the opening 40 of the cylindrical body 26 and the side ends 31, 31 forming the opening 41 of the pipe 28 opposite thereto. , 29a.

  With the above configuration, the inner hole H1 of the cylindrical body 26 and the inner hole H2 of the pipe 28 communicate with each other in the direction orthogonal to the axes J26 and J28 through the space between the connection pieces 29a and 29b. Rainwater flowing in the inside of the calling rod 3 and the elbow 10 flows from the short pipe 16 of the elbow 10 into the inner hole H1 of the cylindrical body 26, and travels along the inclined surface of the bottom 26b from the opening 40 to between the connection pieces 29a and 29a As a result, there is further formed a flow path which flows from the opening 41 into the inner hole H2 of the tube 28 and flows down toward the lower weir 5b.

Engaged portions 24 formed in the circumferential direction to engage the engaging portions 18 are provided on the inner circumferential surface 20I of the fitting rod 20 in the same number as the number of the installed engaging portions 18, that is, two.
Specifically, when the engaged portion 24 is on the inner peripheral surface of the upper end portion of the cylindrical body 26 and the downstream end 10b of the elbow 10 is fitted into the inner hole H1 from above in the direction of the arrow D2. Are formed at positions corresponding to the engaging portions 18. More specifically, as described above, the ring portion 14 and the short pipe 16 are externally fitted in this order to the insertion port 13 of the curved portion 12 and engaged when they are internally fitted into the inner hole H1 from the short pipe 16 side. It is formed at a position corresponding to the portion 18.

  In one embodiment, the engaged portion 24 is a through hole. The circumferential length dimension of the through hole 24 is slightly larger than the circumferential extension dimension of the engaging portion 18, and the engaging portion 18 is engaged with the engaged portion 24. Are set to dimensions that can not move substantially in the circumferential direction in the engaged portion 24.

  The width dimension (dimension in the direction of the axis J26) of the engaged portion 24 is substantially the same as the width dimension of the engaging portion 18, but the protrusion forming the engaging portion 18 penetrates in the direction of arrow D2 (ie, up and down) There is no particular limitation as long as the movement in the hole 24 is restricted and the elbow 10 is not separated from the fitting rod 20 in the direction of the arrow D2. By making the width dimension of the engaged portion 24 approximately the same as the width dimension of the engaging portion 18, the projection 18 is fitted in the through hole 24 and positioned in the direction of the arrow D2, so that it is connected to the elbow 10 and this It is possible to stabilize the call 3 and connect it to the coffin 20.

Then, the construction method of 1 A of connection structures is demonstrated, referring FIGS. 1-3.
When constructing the connection structure 1A, first, the upper collar 5a is internally fitted into the inner hole H2 from above the joint rod 20, and the lower collar 5b is cylindrically spaced from the lower collar 5a at a distance from the upper collar 5a. It inserts to the position below the height of the lowest end of 24 bottom part 26b. As a result, the pair of upper and lower rods 5a and 5b are connected to the upper end and the lower end of the pipe 28 of the rod 20 (see FIG. 2).

Next, the ring portion 14 and the short pipe 16 are externally fitted in this order to the insertion port 13 of the curved portion 12 and the outer peripheral surface C of the insertion port 13 projecting from the ring portion 14 and the upper end of the short pipe 16 externally fitted thereto The elbow 10 is configured by bonding the inner circumferential surface D of the portion with an adhesive or the like (see FIG. 2). At this time, the ring portion 14 is disposed so as to be rotatable relative to the insertion port 13 and the short pipe 16. Elastically deform the elbow 10 or the fitting rod 20 appropriately, insert it into the inner hole H1 from the downstream end 10b side of the elbow 10, that is, the short pipe 16 side, and engage the engaging portion 18 with the engaged portion 24 (See Figure 3).
Thereby, the gutter system provided with the call rod 3, the elbow 10, the joint rod 20 and the rod 5 is completed.

Next, the downstream end portion 3 b of the sump 3 connected to the eaves 4 of the building T shown in FIG. 1 via the water collector 2 is led to the set 20. Here, if the axis J10 at the upstream end of the elbow 10 is offset from the axis J3 of the nominal rod 3, the elbow 10 is rotated in the circumferential direction to make the directions of these axes J3 and J10 coincide (see FIG. 2). After the direction of the axis J10 of the portion extending in the direction of the arrow D1 on the upstream side of the elbow 10 is thus made coincident with the direction of the axis J3 of the weir 3, the weir 3 is upstream of the curved portion 12 of the elbow 10 The side end 12a is inserted into the inner end, and the call rod 3 is connected to the elbow 10.
The connection structure 1A is constructed by the process described above, and the gutter system 8 is installed in the building T.

  As described above, according to the connection structure 1A, the engaging portion 18 provided on the ring portion 14 of the elbow 10 is engaged with the engaged portion 24 provided on the mating rod 20. While the ring portion 14 is circumferentially fixed to the fitting rod 20, the curved portion 12 and the short pipe 16 can rotate around the axis J26 of the cylindrical body 26 of the fitting rod 20 with respect to the fitting rod 20. On the other hand, since the projection is positioned in the through hole in such a way as to be substantially immovable in the direction of the axis J26 (ie, in the direction of the arrow D2), the elbow 10 in the direction of the axis J26 Movement is regulated.

  Therefore, even if the direction of the axis J10 of the elbow 10 is nominally deviated from the direction of the axis J3 of the crucible 3, the elbow 10 is rotated circumferentially around the axis J26 of the crucible 20, Then, the call lever 3 can be easily inserted into the upstream end 10 a of the elbow 10. In addition, after the elbow 10 is inserted into the fitting rod 20, as described above, the engaging portion 18 of the elbow 10 is engaged with the engaged portion 24 of the fitting rod 20. The movement of the elbow 10 in the direction is restricted, so that it is possible to reliably prevent the hook 10 connected to the elbow 10 or the elbow 10 from coming off the joint rod 20.

  Further, according to the connection structure 1A of the embodiment, since the call rod 3 and the joint rod 20 are firmly fixed via the elbow 10, the downstream end 10b of the elbow 10 is bonded to the joint rod 20 with an adhesive or the like. There is no need to Therefore, when the dead leaf or the dust conveyed through the upper side ridge 5 or the callout ridge 3 gets stuck in the combination ridge 20, the engagement portion 18 and the hook 10, the elbow 10 and the ridge 5 are not cut. The engagement with the engaged portion 24 is released, the elbow 10 is put out of alignment, and it is possible to easily remove stuck dead leaves, dirt, and the like.

  Thus, maintenance of connection structure 1A and gutter system 8 can be performed easily. Further, it is not necessary to apply a pressing tool or the like to the elbow 10 in order to prevent removal of the elbow 10 inserted into the fitting rod 20 as in the prior art, and the occurrence of damage to the elbow 10 can also be prevented.

  In the connection structure 1A of the embodiment described above, the engaging portion 18 is a projection that protrudes outward in the radial direction of the ring portion 14, and the engaged portion 24 is a through hole. Is a through hole, and the engaged portion 24 may be a projection that protrudes inward in the radial direction of the cylindrical body 26 of the mating rod 20.

  As described above, according to the connection structure 1A, the elbow 10 described above can be configured by combining the bending portion 12 which is a member widely used in the past, the ring portion 14 and the short tube 16. Therefore, the joint rod 20 can be manufactured inexpensively.

  In the above embodiment, although the case where the engaged portion 24 is a through hole has been described as an example, as long as the engagement portion 18 can be engaged to restrict movement of the elbow 10 in the axial direction, The joint portion 24 may be a groove instead of the through hole.

  Further, in the above embodiment, the present invention has been described using an example in which the elbow 10 is constituted by the curved portion 12, the ring portion 14 and the short pipe 16, but as shown in FIG. May be integrally formed. In this case, the engaged portion 24 has a length such that the groove or elbow 10 continuous in the circumferential direction can be rotated by a predetermined angle (for example, an angle of 90 degrees or less around the axis line J3 of the hammer 3). It may be a groove or a through hole formed by

  By forming the engaged portion 24 over the entire circumferential direction of the cylindrical body 26 in this manner, a rotational angle about the axis J12 of the elbow 10 with respect to the axial line J26 of the mating rod 20 cylindrical body 26 is secured. Further, when connecting the call rod 3 and the elbow 10, the direction of the axis J10 of the upstream end portion 10a of the elbow 10 can be easily made to coincide with the direction of the axis J3 of the call rod 3.

  In the connection structure 1B of the modified example described above, the engaging portion 18 is a projection that protrudes outward in the radial direction of the elbow 10, and the engaged portion 24 is a groove, but the engaging portion 18 is a groove. Alternatively, the engaged portion 24 may be a projection that protrudes inward in the radial direction of the cylindrical body 26 of the mating rod 20. Also in such a configuration, the same function and effect as the connection structure 1B of the above-described modification can be obtained.

  Although the preferred embodiments of the present invention have been described above in detail, the present invention is not limited to the specific embodiments, and various modifications may be made within the scope of the present invention as set forth in the appended claims. Modifications and changes are possible.

  The engaging portion 18 and the engaged portion 24 may not necessarily be formed at one position in the direction of the axis J26 of the mating rod 20, and may be formed at two or more positions. According to such a configuration, in the same way as the connection structure 1 of the above embodiment, in addition to the elbow 10 being rotatable in the direction of the axis J26 of the mating rod 20, the direction of the axis J26 of the mating rod 20 in the elbow 10 Movement is more reliably suppressed within the allowable range, and it is possible to prevent the elbow 10 and the call rod 3 from coming off the joint rod 20 more reliably.
