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. It is strongly desired to develop products that can further enhance the “showing function” of the bag.

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 separate rotating blade portion 5 is fitted into the cylindrical body 4 and attached by the locking means 7, it has a complicated shape (the central shaft portion 12 having the hole 18 in the cylindrical body 4) in order to provide a rotating function. It is possible to easily assemble and form the chain element body 1 having a complicated shape in which the rotating blade portion 5 configured by projecting the blade portion 13 on the peripheral portion is provided.

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 provided. An example is shown in which a chain rod 2 in which a plurality of chain rod bodies 1 are arranged in the vertical direction is configured by connecting the two by the connecting portion 10.

  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. . Thus, by assembling the separate cylindrical body 4 and the rotary blade part 5 to constitute the chain element body 1, even if the rotary blade part 5 has a complicated shape as described below, The rotor blades 5 can be easily molded separately from each other using a synthetic resin.

  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. On the inner surface of the wall portion of the cylindrical body 4, a locking means 11 made of a protrusion that constitutes the locking means 7 protrudes from the opening edge of the upper opening 6 at a position below the opening dimension by a fixed dimension.

  The rotary blade portion 5 is configured by projecting one or more blade portions 13 around the central shaft portion 12, and the blade portions 13 are twisted so as to be spiral 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 rotating blade portion 5 is fitted from the upper opening 6 of the cylinder body 4 so that the protruding side ends of the plurality of blade portions 13 abut against the inner surface of the wall portion of the cylinder body 4 and the upper ends of the blade portions 13 are engaged with the locking means 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.
