Description

  The present invention relates to a chain rod in which a plurality of chain rods are arranged in the vertical direction so that rainwater drained from the eaves can flow down along the chain rods.

  Conventionally, Japanese Patent Application Laid-Open No. 2004-133867 discloses a chain rod that allows rainwater drained from an eave wall to flow down along a chain element.

  In the conventional example shown in Patent Document 1, a cylindrical chain element having a truncated cone shape opened up and down is connected vertically by a connecting portion. Rain water flowing from the lower opening of the body flows to the upper opening of the lower cylindrical chain element, and the rain water flows downward between the upper and lower cylindrical chain elements However, rainwater that flows down from the lower opening of the upper cylindrical chain element scatters. However, rainwater that only flows under its own weight, such as when wind is blowing, may not flow well into the upper opening of the lower cylindrical chain element. There is a problem of scattering outside.

  In this conventional example, the lower opening of the cylindrical chain element is made smaller in diameter than the upper opening in order to suppress the scattering of rainwater flowing downward from the lower opening of the upper cylindrical chain element as much as possible. The rainwater flowing downward from the lower opening is throttled as much as possible, and the rainwater scattered between the upper and lower chain elements can be received by the upper opening with the larger diameter of the lower chain element, but still scattered. There is no change in being easy, and there is a case where it cannot be sufficiently received by an upper opening having a large diameter. In particular, when wind blows, scattering cannot be prevented.

Moreover, in the said prior art example, it is limited to the thing of the truncated cone-shaped external appearance which makes the lower opening of a cylindrical chain rod body a smaller diameter than an upper opening, and there exists a restriction | limiting in an external shape.
Japanese Utility Model Publication No. 5-7825

  The present invention has been invented in view of the above-described conventional problems, and can show a state in which rainwater flows down while spirally swirling while preventing the rainwater from scattering, and the lower opening is raised above. Of course, when the diameter is smaller than the opening, it is possible to make the diameter almost the same, and it is an object of the present invention to provide a chain rod that increases the degree of freedom of the external shape of the chain element.

In order to solve the above-mentioned problem, the chain rod according to the present invention is a chain rod 2 in which a plurality of non-rotating chain rod bodies 1 are arranged in a vertical direction with a gap between the upper opening 3 and the lower opening. 4 and a spiral plate portion 6 having a spiral shape around the central axis 9 is provided in the cylindrical body 5 with the lower opening portion as rainwater flowing from the upper opening portion 3 as a spiral flow. The spiral rainwater flow path 7 for flowing down from 4 is formed to constitute the chain element body 1.

  By adopting such a configuration, the rainwater flowing from the upper opening 3 of the chain element 1 is spirally spiraled along the spiral rainwater flow path 7 provided in the cylindrical body 5. A spiral flow from the lower opening 4 flows downward, and this rainwater spiral flow flows into the upper opening 3 of the lower chain element 1. Since it flows down as a spiral flow in this way, it is difficult to scatter between the lower opening 4 of the chain element 1 and the upper opening 3 of the lower chain element 1. Further, the conventional chain ridge 2 shows a flow of water flowing down straight, but in the present invention, it is possible to show a flowing spiral flow while drawing a spiral that could not be obtained with the conventional chain ridge 2.

  Further, it is preferable to form a spiral rainwater flow path 7 by providing a spiral plate portion 6 having a spiral shape around the central axis in the cylindrical body 5. By having such a configuration, the rainwater flows along the spiral plate portion 6 provided in a spiral shape around the central axis, so that the rainwater flows down while rotating around the central axis of the cylindrical body 5, The spiral flow that flows down from the lower opening 4 of the upper chain element 1 around the central axis flows down from the upper opening 3 of the lower chain element 1 around the central axis, and thus more scattering occurs. It can be prevented.

  The present invention is provided with a spiral rainwater flow path for flowing rainwater flowing in from the upper opening as a spiral flow as described above, so that the rainwater flowing down from the lower opening becomes a spiral flow. It is possible to prevent scattering and to show the rainwater flowing down in a spiral flow, so that a new rainwater flow-down state that could not be shown in the conventional chain is shown and shown. In addition, since the spiral flow has a flow prevention effect, it can of course have the same diameter when the lower opening is made smaller than the upper opening. The degree of freedom increases.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The chain rod 2 of the present invention has a plurality of chain rod bodies 1 arranged in the vertical direction via gaps 11, and rainwater flowing down from the eave rods with the upper ends connected to the eave rods 1 It is intended to make it flow down one after another.

  The chain elements 1 arranged in the vertical direction cannot be rotated with each other. In the embodiment shown in FIGS. 1 to 3, the linear chain 8 that is long in the vertical direction such as a wire or a bar is used. A plurality of element bodies 1 are respectively attached in the vertical direction. In this case, the chain element body 1 is attached so as not to rotate with respect to the linear material 8.

  The chain element 1 has a spiral rainwater flow path 7 formed by providing a spiral plate portion 6 around the central shaft portion 9 spirally in a cylindrical body 5. The outer peripheral edges are in contact with, fixed to, or integrated with the central shaft portion 9 and the inner surface of the cylindrical body 5.

  In the present embodiment, when rainwater flows into the chain body 1 from the upper opening 3 of the tubular body 5 of the cylindrical body 1, the rainwater is formed in the spiral shape formed around the central shaft portion 9. It hits the inclined surface of the plate part 6 and flows down as a spiral flow on the spiral plate part 6, and flows down as a spiral flow a downward from the lower opening 4 of the cylindrical body 5, and goes down through the gap 11. It flows down into the upper opening 3 of the cylinder 5 of another chain element 1 located.

  Similarly, a spiral flow flows along the spiral plate portion 6 in the cylindrical body 5 of the lower chain element 1, and spiral flow from the lower end opening 4 of the cylindrical body 5 of the lower chain element 1. Then, it flows down into the upper opening 3 of the cylindrical body 5 of another chain element body 1 located further below through the gap 11.

  As described above, in the present invention, rainwater flows down the gap 11 between the chain rod bodies 1 as a spiral flow a, and thus flows down from the lower opening 4 of the upper chain rod body 1. Therefore, the rainwater is not easily scattered and flows down into the upper opening 3 of the lower chain element 1 surely.

Also, chain of ornamental cups hanging from a gutter 2 of traditional but were those show the flow of water straight flow down, in the present invention, it is to show a spiral flow b flowing drawing a conventional spiral that can not be obtained in the chain of ornamental cups hanging from a gutter 2 it can.

Here, like the embodiment of FIGS . 4 and 5, the chain element 1 having a gentle inclination angle of the spiral plate portion 6 shown in FIG. 6 and the inclination angle of the spiral plate portion 6 shown in FIG. If the chain rod bodies 1 are mixed in the vertical direction, the speed of the spiral flow of rainwater is different. Therefore, in the vertical direction, the gap 11 between the chain rod bodies 1 has a fast flow spiral flow and a slow flow. It is possible to provide the chain rod 2 in which the spiral flow C is mixed in the vertical direction.

  Further, as shown in FIG. 7 and FIG. 8, a chain rod 2 may be formed by mixing a plurality of chain rods having different spiral winding directions of the spiral plate portion 6 up and down, and in this case, the spiral flow of rainwater Therefore, the spiral rod 2 in which the spiral flow 2 rotating in one direction through the gap 11 between the chain rod bodies 1 in the vertical direction and the spiral flow ho rotating in the opposite direction are mixed in the vertical direction. Can provide.

  Further, as in the embodiment of FIGS. 7 and 8, the chain element 1 in which the inclination angle of the spiral plate portion 6 is loose and the spiral direction is one direction, and the inclination angle of the spiral plate portion 6 becomes steep. When the chain elements 1 whose spiral directions are opposite to each other are mixed in the vertical direction, the speed and rotation direction of the spiral flow of rainwater differ, and therefore the gap 11 between the chain elements 1 in the vertical direction. It is possible to provide a chain 2 in which spiral flows having different speeds and rotational directions are mixed in the vertical direction.

  In the above example, a chain rod 2 is formed by attaching a plurality of chain rod bodies 1 to a linear member 8 that is long in the vertical direction, such as a wire or a bar, so as not to rotate. In this way, connecting portions 10 are respectively provided above and below the chain rod body 1 provided with the rainwater flow path 7 in the cylindrical body 5, and the upper and lower chain rod bodies 1 are connected to each other and the chain rods 2 are rotated with each other. You may make it comprise the chain 2 by connecting so that it may not.

  In the above-described embodiment, the cylindrical body 5 constituting the main body of the chain element 1 has a lower opening 4 smaller than the upper opening 3 as shown in FIG. The rainwater flowing down as a spiral flow a is allowed to flow into the large-diameter upper opening 3 of the lower chain rod body 1 so as to further suppress scattering of rainwater flowing from the lower opening 4. However, in the present invention, it flows as a spiral flow from the lower opening 4 and flows down while acting such that rainwater collects on the center side, so the lower opening 4 and the upper opening 5 The rainwater flowing down from the lower opening 4 can be poured into the upper opening 3 while suppressing scattering by the spiral flow, and therefore, for example, as the cylinder 5 in the vertical direction It is possible to have the same diameter or almost the same diameter, and the degree of freedom of the outer shape of the chain element 1 Increases, the degree of freedom in design is increased.

  In each of the above embodiments, the central shaft portion 9 is provided in the cylindrical body 5 and the spiral plate portion 6 is spirally provided around the central shaft portion 9. However, there is no central shaft portion 9, The spiral plate portion 6 may be formed so as to draw a spiral around the virtual central axis of the cylindrical body 5.

  In the case where the spiral plate-like portion 6 is formed so as to draw a spiral around the central shaft portion 9, the spiral plate-like portion 6 is formed so as to draw a spiral around the virtual central axis without the central shaft portion 9. However, when rainwater flows along the spiral plate portion 6 provided spirally around the central axis, the rainwater turns into a spiral flow that flows around the central axis of the cylindrical body 5, and the upper chain element 1 The spiral flow that flows down from the lower opening 4 around the central axis flows down from the upper opening 3 of the lower chain element 1 around the central axis, so that scattering can be further prevented.

  In any of the above-described embodiments, the entire or a part of the cylinder 5 is transparent so that rainwater flows in the cylinder 5 along the rainwater flow path 6 as a spiral flow. Will be able to.
