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.

  2. Description of the Related Art Conventionally, a chain rod that allows rainwater drained from an eave wall to flow down through a chain rod is known.

  As a conventional chain rod, for example, there is one in which ring-shaped chain rods are connected in a chain shape. This chain-shaped chain rod is configured by passing a ring-shaped chain rod body vertically so as to cross each other vertically.

  Moreover, the upper joint part which carried out the reverse U-shape on the upper and lower sides of the cylinder as a chain element, and the lower joint part which carried U-shape protruded, and the lower joint part which carried the U-shape on the upper and lower chain element bodies, Patent Document 1 and the like are known in which a chain rod is configured by passing through an inverted U-shaped upper connecting portion so as to cross and connecting up and down.

  The general downpipe has a cylindrical shape that prevents rainwater from flowing down, but the above-mentioned chain fence flows down the rainwater drained from the eaves along the chain element. By showing, it has the characteristic that it can be made into a quaint thing which is not in a cylindrical downspout.

However, any of the above-described conventional chains has only a function to show how rainwater flows down the chain body. For this reason, the chain function “function to show (function to show the flow down the chain body)” has become rutted, and it is currently impossible to provide a chain with high commercial value. There is a strong desire to develop products that will further enhance the “function of showing” that acupuncture has.

  The present invention has been invented in view of the above-described conventional problems, and has a function of rotating a chain element by a flowing water force of rainwater, thereby providing a new “showing function” that is not found in a conventional chain chain. In addition, the chain rod that rotates the chain element with the flowing water of rainwater can prevent splashing of the splash when the chain rod body rotates, and can prevent splashing of nearby people and outer walls. It is a problem to provide.

  The present invention is a chain rod 2 in which a plurality of chain rod bodies 1 are arranged in the vertical direction. In the present invention, the chain element 1 is rotatably attached to the shaft 3, and the rotating blade for rotating the cylinder 4 by receiving the flowing water of rainwater in the cylinder 4 opened up and down. The chain body 1 is configured by providing the portion 5, and the upper end of the rotary blade portion 5 provided in the cylindrical body 4 is positioned at a position where it is drawn below the upper end of the cylindrical body 4. Is.

  With such a configuration, the rainwater flowing from the lower opening 8 of the cylinder 4 of the upper chain element 1 flows into the cylinder 4 from the upper opening 6 of the cylinder 4 of the lower chain element 1. The chain element body 1 can be rotated by being received by the rotary wing part 5 provided in the cylindrical body 4 and the chain element body 1 is rotated by the flowing water force of the rainwater. It is possible to provide a chain 2 having a new function that could not be exhibited by the chain 2 of FIG. In addition, since the chain rod body 1 is rotated by using the flowing water force of rainwater acting on the chain rod body 1, the configuration of the chain rod 2 can be simplified. Further, since the upper end of the rotary blade portion 5 provided in the cylindrical body 4 is positioned at a position where the upper end of the cylindrical body 4 is drawn below the upper end of the cylindrical body 4, the lower opening 8 of the cylindrical body 4 of the upper chain body 1. The rainwater flowing down from the pipe flows into the cylinder 4 from the upper opening 6 of the cylinder 4 of the lower chain element 1 and is received by the rotary blade portion 5 provided in the cylinder 4 to receive the chain element 1. When rotating, the falling water received by the rotary blade portion 5 is prevented from splashing out from the upper opening 6 of the chain rod body 1.

  Moreover, it is preferable that the inner edge and the outer edge of the edge part of the upper opening 6 of the cylinder 4 are chamfered.

  Even if rain water flows down from above and hits the upper part of the inner wall of the cylinder 4 of the chain rod body 1 or the upper part of the rotary blade part 5 and goes up along the inner wall, the edge of the upper opening 6 of the cylinder 4 Since the inner edge and the outer edge of the portion are chamfered, they flow along the chamfered portions of the edge and the outer edge of the upper opening 6 and flow downward along the outer surface of the cylindrical body 4 and are scattered outside. Can be prevented from jumping out.

  Further, the inner collar portion 7 protrudes inward from the edge of the upper opening 6 of the cylinder 4, and the lower opening 8 of the cylinder 4 is smaller than the upper opening 6 of the cylinder 4. preferable.

  With such a configuration, rainwater flowing down from the lower opening 8 of the upper cylindrical body 4 flows into the cylindrical body 4 from the upper opening 6 of the cylindrical body 4 of the lower chain body 1 and is cylindrical. Even if it hits the upper part of the inner wall of 4 or the upper part of the rotary wing part 5 and goes up along the inner wall, rainwater is projected by the inner flange part 7 projecting inwardly at the edge of the upper opening 6 of the cylinder 4. Can be prevented from splashing outside.

  As described above, the present invention provides a rotating blade portion for rotating the cylindrical body by receiving a flowing force of rainwater in a cylindrical body that is opened up and down, and is attached to the shaft body so as to be rotatable. Since it has a chain structure, it has a function to show how the chain element rotates by the flowing water of rainwater, and it has a simple structure and is completely new to the conventional chain. It is possible to provide a chain with high commercial value that has a “show function”. In addition, since the upper end of the rotary wing for rotating the cylinder under the rainwater flow force is located at a position drawn below the upper end of the cylinder, the rainwater flow force is received by the rotor blade. In spite of the rotation, it is possible to prevent splashes from splashing when the chain element rotates, and to prevent the nearby person and the outer wall from being splashed.

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

  The chain rod 2 of the present invention is formed by arranging a plurality of chain rod bodies 1 in the vertical direction through gaps 9, and connecting rain water flowing down from the eave rod with the upper end connected to the eave rod 1 It is intended to make it flow down one after another.

  In the present invention, all the chain rod bodies 1 or a part of the chain rod bodies 1 constituting the chain rod 2 are rotatable with respect to the shaft body 3.

  FIG. 1 to FIG. 3 show an embodiment of the present invention. In this embodiment, rotation for rotating the cylindrical body 4 by receiving the flowing water of rainwater in the cylindrical body 4 opened up and down. The chain element body 1 is configured by providing the wing part 5, the shaft body 3 is rotatably attached to the chain element body 1, the connecting part 10 is provided on the shaft body 3, and the upper and lower chain element bodies 1 are connected. An example in which a chain rod 2 in which a plurality of chain rod bodies 1 are arranged in the vertical direction is configured by being connected by the portion 10 is shown.

  In the embodiment, there is shown an example in which the chain element body 1 is configured by attaching the rotary blade portion 5 separate from the cylinder body 4 in the cylindrical body 4 having a square shape or a circular shape with an open top and bottom. . In this way, by assembling the separate cylindrical body 4 and the rotary blade portion 5 to form the chain element body 1, even if the rotary blade portion 5 has a complicated shape, it can be easily molded from a synthetic resin. Can do.

  The cylindrical body 4 is formed such that the lower opening 8 is smaller than the upper opening 6 and the cross-sectional shape of the cylindrical body 4 gradually decreases from the top to the bottom. A locking projection 11 projects from the inner surface of the wall portion of the cylindrical body 4 at a position drawn below a certain dimension from the opening edge of the upper opening 6.

  The rotary blade portion 5 is configured by radially projecting blade portions 13 around the central shaft portion 12, and the blade portions 13 are twisted so as to have a spiral shape around the central shaft portion 12. Further, the protruding side end of each blade portion 13 has the same inclination as the inclination of the inner surface of the wall portion along the inner surface of the wall portion of the cylindrical body 4. Further, a hole 18 penetrating vertically is provided in the central shaft portion 12.

  The rotor 5 is fitted from the upper opening 6 of the cylinder 4 so that the protruding side ends of the plurality of blades 13 abut against the inner surface of the wall of the cylinder 4 and the upper ends of the blades 13 are engaged with the locking projections 11. The rotor blade 5 is housed inside the cylinder 4 by being locked. In this state, the position of the upper end of the rotor blade 5 is a fixed dimension (dimension L in FIG. 1) from the upper end of the cylinder 4. The center shaft portion 12 is coaxial with the center axis of the cylinder 4.

  The shaft body 3 is vertically divided into an upper shaft portion 14 and a lower shaft portion 15, and a connecting portion 10 is provided at each of an upper end portion of the upper shaft portion 14 and a lower end portion of the lower shaft portion 15. A connecting portion 16 is provided at the lower end portion of the upper shaft portion 14, and a connected portion 17 is provided at the upper end portion of the lower shaft portion 15.

  One or both of the upper shaft portion 14 to the lower shaft portion 15 is loosely inserted into the hole 18 of the central shaft portion 12 of the chain element 1, and the connecting portion 16 and the connected portion 17 are connected. Thus, the chain element body 1 is rotatable with respect to the shaft body 3 constituted by the upper shaft portion 14 and the lower shaft portion 15. The lower shaft portion 15 is provided with a fall prevention portion 19 for dropping the lower end portion of the central shaft portion 12.

  As described above, the chain rod 2 is formed by connecting the plurality of chain rod bodies 1 that are rotatable to the shaft body 3 with the connecting portion 10 up and down.

  When rainwater flows into the chain rod body 1 from the upper opening 6 of the cylindrical chain rod body 1, the rainwater hits the inclined surface of the spiral rotor blade 5 formed around the central shaft portion 12. The rotor blade 5 flows down as a spiral flow on the rotor blade 5. At this time, the rotor blade 5 comes into contact with the inclined surface of the rotor blade 5 from the upper opening 6 as shown by the arrow A in FIG. A force that rotates around the body 3 acts, and the rainwater flows in a spiral flow along the spiral rotor blade 5 to flow through the chain body 1, thereby Further, a rotating force acts, whereby the chain element 1 rotates about the shaft 3 as shown by the arrow B in FIG.

  In this way, the rainwater that has become a spiral flow itself while rotating the chain element 1 flows downward as a spiral flow from the lower opening 8 of the cylindrical body 4, and flows through the gap 9 to another position located below. It flows down into the upper opening 6 of the chain element 1.

  The rainwater flowing down from the upper opening 6 of another chain element 1 located below hits the inclined surface of the spiral rotating blade portion 5 in the same manner as described above and flows down as a spiral flow on the rotating blade portion 5. As a result, the lower chain element 1 rotates around the shaft 3 in the same manner as described above.

  Similarly, all the chain rod bodies 1 can be rotated by successively rotating the lower chain rod body 1 around the shaft body 3.

  In this embodiment, when rainwater flows as described above, it can be seen that the chain element 1 rotates due to the rainwater flow force, and the rainwater spirals in the gap 9 between the upper and lower chain element bodies 1. You can see the flow as a stream. As a result, the conventional chain rod body 1 does not rotate, and in the gap 9 between the chain rod bodies 1, it can appear in the conventional chain rod 2 as compared with the case where only rainwater can be seen flowing straight. The movement of rainwater and the movement of the chain element 1 that was not present can be revealed.

  As described above, the chain element 1 is rotated using the rainwater flow force, but the rainwater flows down as a spiral flow from the lower opening 8 of the upper chain element 1 that rotates. Then, it flows into the chain element body 1 located below from the upper opening 6 of the chain element body 1 that rotates below, but the rotating blades inclined to rotate the chain element body 1. The rain water flowing down from above needs to collide with the inclined surface of the portion 5 so that the rain water flowing down from the upper opening 6 collides with the inclined surface of the rotary wing portion 5 and the force of the collision. When the chain element 1 rotates, water may be scattered.

  However, in the present invention, the upper end of the rotary blade portion 5 provided in the cylindrical body 4 is positioned at a position where it is drawn below the upper end of the cylindrical body 4. The rainwater flowing down from the lower opening 8 of the cylinder 4 flows into the cylinder 4 from the upper opening 6 of the cylinder 4 of the lower chain element 1 and is received by the rotary blade portion 5 provided in the cylinder 4. When rotating the silicon body 1, the flowing water received by the rotary blade part 5 is prevented from scattering outside the upper opening 6 of the chain body 1.

  Here, by colliding with the rotor blade 5 located at a position drawn downward from the upper opening 6 of the chain rod body 1, it was scattered at a position drawn downward from the upper opening 6 of the chain rod body 1. A part of the splash hits the upper part of the inner wall of the cylinder 4 or the upper part of the rotary wing part 5 and may go back up along the inner wall. However, as shown in FIG. When the chamfered portion 20 is formed by chamfering the inner edge and the outer edge of the edge portion 6, rainwater that goes back the wall portion flows along the chamfered portions of the inner edge and the outer edge of the upper opening 6 and flows into the cylindrical body 4. It will flow down along the outer surface, and it can be prevented from splashing out and jumping out.

  FIG. 5 shows still another embodiment of the present invention. In this embodiment, an inner collar portion 7 is projected inwardly at the edge of the upper opening 6 of the cylindrical body 4. In the present embodiment, the size of the upper opening 6 is a portion surrounded by the inner flange portion 7, but the upper opening 6 is also larger than the lower opening 8 in this embodiment, and therefore, the upper chain rod body. The rainwater flowing down from the lower opening 8 of 1 is allowed to flow smoothly from the upper opening 6 of the lower chain element 1.

  In this embodiment, since the inner collar portion 7 projects inward from the edge of the upper opening 6 of the cylinder 4, the rainwater flowing down from the lower opening 8 of the upper cylinder 4 Even if it flows into the cylinder 4 from the upper opening 6 of the cylinder 4 of the chain element 1 and hits the upper part of the inner wall of the cylinder 4 or the upper part of the rotary wing part 5, it goes back along the inner wall, It is possible to prevent rainwater from splashing outside by the inner flange portion 7 projecting inwardly at the edge of the upper opening 6 of the cylindrical body 4.

  In the above-described embodiment shown in FIG. 1 and FIG. 2, an example in which the spiral winding direction in the rotary blade portion 5 of the plurality of chain rods 1 arranged in the vertical direction is the same direction is shown. In this case, the chain rod 2 is drained while rotating the plurality of chain rod bodies 1 in the same direction by the flowing force of rainwater, but the spiral winding direction in the rotary blade portion 5 of the plurality of chain rod bodies 1 is the same. By mixing the one that is in one direction and the one that is in the opposite direction, the chain element 1 that rotates in one direction due to the flow of rainwater and the chain element 1 that rotates in the opposite direction are mixed. In this embodiment, the movement of the rainwater and the movement of the chain element 1 that could not appear in the conventional chain 2 can be revealed.

  In any of the above-described embodiments, the chain rod 2 may be configured by using a plurality of chain rod bodies 1 having different inclination angles of the rotary blade portion 5, and in this case, a chain rod having a high rotation speed is used. The body 1 and the slow chain element 1 are mixed, and the movement of the rainwater and the movement of the chain element 1 that cannot be revealed by the conventional chain 2 can be revealed.

  Moreover, in the said embodiment, the shaft body 3 is rotatably attached to the chain rod body 1, the connecting portion 10 is provided on the shaft body 3, and the upper and lower chain rod bodies 1 are connected by the connecting portion 10, Although an example in which a chain rod 2 in which a plurality of chain rod bodies 1 are arranged in the vertical direction is shown, the shaft body 3 is made of a linear material (not shown) that is long in the vertical direction, such as a wire or a bar. The chain rod body 1 may be formed by attaching the chain rod body 1 to the linear material so as to be rotatable a plurality of times in the vertical direction.
