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” (the function of showing the flow down the chain body) has become a rut, and it is currently impossible to provide a chain with high commercial value. There is a strong desire to develop products that further enhance the “showing function” of the bag.

  The present invention has been invented in view of the above-described conventional problems, and has a function of rotating a chain element by flowing water of rainwater or wind power, thereby providing a new “show function” that is not found in conventional chain rods. It is an object of the present invention to provide a chain rod provided with “

In order to solve the above problem, the chain according to the present invention is a chain 2 in which a plurality of chain elements 1 are arranged in the vertical direction. The chain rod body 1 is rotatably attached to the shaft body 3, and the chain rod body 1 attached to the shaft body 3 so as to freely rotate is allowed to flow into the tubular body 7 opened vertically. A rotating action part 4 that rotates the chain element body 1 by receiving a force, and a rotating action part 4 that rotates the chain element body 1 by receiving wind force on the blade part 13 protruding from the outer peripheral surface of the cylindrical body 7. It is characterized by providing.

By having such a structure, the function of showing the state that the chain rod body 1 rotates by natural force by rotating the chain rod body 1 by receiving the flowing hydropower or wind power of the flowing rainwater at the rotating action unit 4. ”And can provide a chain 2 having a new function that cannot be exhibited by the conventional chain 2. In addition, when the chain rod body 1 is rotated, the structure of the chain rod 2 can be simplified because it is rotated using the rainwater flow force or the natural force acting on the chain rod body 1 such as wind power.
Further, the chain element 1 can be rotated by wind and rainwater flow force. When there is no precipitation but the wind is blowing, the wind is not blowing but the precipitation is raining and the wind is blowing In any case, the chain element 1 can be rotated.

  Further, the shaft body 3 is constituted by the linear material 5 that is long in the vertical direction, and a plurality of chain element bodies 1 are attached to the linear material 5 in the vertical direction, and all or some of the plurality of chain element bodies 1 are lined. It is preferable to be rotatable with respect to the material 5.

  By adopting such a configuration, a plurality of chain element bodies 1 are attached to the shaft body 3 by the linear material 5 that is long in the vertical direction, so that the rotation action portion 4 is provided with respect to the shaft body 3 with a simple configuration. The chain rod body 1 can be rotatably attached to form the chain rod 2.

  Moreover, it is preferable to provide the connection part 6 in the shaft 3 to which the chain element 1 is rotatably attached, and to connect the upper and lower chain element 1 with the connection part 6.

  In this way, the chain element bodies 1 that are rotatably attached to the shaft body 3 are connected to each other by the connecting portion 6, and the number of chain element bodies 1 to be connected is adjusted, thereby allowing the freely rotatable chain element body 1. Can be easily formed.

  Further, it is preferable to provide means 19 for floating the chain element 1 attached to the shaft body 3 so as to be rotatable.

  By adopting such a configuration, the chain element 1 can be rotated with a small force with respect to the shaft body 3, and even when the amount of rainwater flowing is small or the wind power is small, the chain can be smoothly chained. The silicon body 1 can be rotated.

  In the present invention, the chain element body is rotatably attached to the shaft body as described above, and the chain element body rotatably attached to the shaft body is subjected to rainwater flow force or wind power to receive the chain element. Since the rotary action part for rotating the silicon body is provided, it has the function of showing the state that the chain element is rotated by the flowing water force or wind power of rainwater, It is possible to provide a chain with high commercial value with a completely new “showing function” not found in chains.

  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 elements 1 arranged in the vertical direction via gaps 16, and the 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.

  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.

1 to 3 show a form of a reference example for explaining the present invention. In the form of this reference example, the shaft body 3 is composed of a linear material 5 that is long in the vertical direction, such as a wire or a bar. A plurality of chain element bodies 1 are attached to the linear material 5 in the vertical direction, and all or a part of the plurality of chain element bodies 1 are rotatably attached to the linear material 5. In order to rotatably attach the chain element 1 to the shaft 3 made of the linear material 5, for example, a center shaft part 10 is provided at the center of the chain element 1 and penetrates the center shaft part 10 vertically. Open the hole 11, loosely insert the linear material 5 into the hole 11, and place the lower end of the central shaft portion 10 on the fall prevention portion 12 provided in the linear material 5, thereby making the linear element body 1 linear. Attached to the material 5 in a rotatable manner.

  The chain element 1 that is rotatably attached to the shaft body 3 (the linear material 5) is provided with a rotation action unit 4 for rotating the chain element body 1 by receiving the flowing hydropower or wind power of rainwater. It is.

In the form of the reference example shown in FIG. 1 to FIG. 3, the rotary action portion 4 is configured by providing the rotating blade portion 13 around the central shaft portion 10 in a spiral shape within the cylindrical body 7. The inner peripheral edge and the outer peripheral edge of the blade portion 13 are in contact with, fixed to, or integrated with the central shaft portion 10 and the inner surface of the cylindrical body 7, respectively.

In this embodiment , when rainwater flows into the chain rod body 1 from the upper opening 14 of the cylindrical chain rod body 1, the rainwater is formed in the spiral rotating blade portion 13 formed around the central shaft portion 10. 1, and flows down as a spiral flow on the rotary blade portion 13. At this time, it hits the inclined surface of the rotary blade portion 13 from the upper opening 14 as indicated by the arrow a in FIG. 1. A rotating force acts on the linear member 5 that is the shaft body 3 as the rotating blade portion 13, and the rainwater becomes a spiral flow along the spiral rotating blade portion 13. By flowing through the inside, a force that further rotates the chain element 1 acts, whereby the chain element 1 rotates about the linear member 5 as shown by an 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 15 of the cylindrical body 7, and flows through another gap 16 located below through the gap 16. It flows down into the upper opening 14 of the chain element 1.

  Rainwater that flows down from the upper opening 14 of another chain element 1 located below hits the inclined surface of the spiral rotating blade portion 13 in the same manner as described above and flows down as a spiral flow on the rotating blade portion 13. Accordingly, the lower chain element 1 is rotated around the linear member 5 in the same manner as described above.

  Similarly, all the chain rod bodies 1 can be rotated by rotating the lower chain rod body 1 around the linear material 5 one after another.

In the embodiment of this reference example, when rainwater flows as described above, it can be seen that the chain element 1 rotates due to the flowing water force of the rainwater, and in the gap 16 between the upper and lower chain element bodies 1, You can see the flowing as a spiral flow. As a result, the conventional chain rod 1 does not rotate, and the conventional chain rod 2 can appear as compared with the case where only the rainwater can be seen flowing in the gap 16 between the chain rod bodies 1. The movement of rainwater and the movement of the chain element 1 that was not present can be revealed.

Of course, in the above reference example , the description has been given of the example in which the entire chain element 1 can be rotated with respect to the linear member 5 constituting the shaft body 3. 4, and can be rotated with respect to the shaft body 3, but the other chain element 1 may not be provided with the rotation action part 4 and may not be rotated. Among some of the plurality of chain rod bodies 1 constituting, some chain rod bodies 1 rotate, some of the chain rod bodies 1 do not rotate, and rainwater spirals from the lower end of the rotating chain rod body 1 It can be seen that it is flowing down, and the rainwater is seen to flow straight down from the lower end of the non-rotating chain element 1, and the rotating chain element 1 and the non-rotating chain element 1 are mixed in the vertical direction. At the same time, the spiral flow and the straight flow are mixed in the vertical direction. It can provide a chain of ornamental cups hanging from a gutter 2 bets is emphasized.

  Further, the rotational speed of the chain element 1 varies depending on the flow rate of rainwater flowing through the chain element 1. For this reason, the rotational speed of the chain element 1 changes in response to the change in the flow rate of rainwater flowing through the chain 2, and also in this respect, the amount of rain changes with the passage of time in the rain, As a result, it is possible to obtain a graceful chain 2 in which the rotation speed changes as time passes.

In the form of the reference example shown in FIGS. 1 to 3, a plurality of rotating chain elements 1 are rotated in the same direction by the flowing water of rainwater. Of course, the present invention is not limited to this, and as shown in FIGS. 4 and 5, one of the rotating chain element bodies 1 rotates in one direction, and the other rotating chain element body 1 rotates in the one direction ( You may make it rotate in the opposite direction (arrow D direction) to the arrow B direction. In this case, as the chain rod body 1 to be used, the spiral winding direction of the chain rod body 1 shown in FIG. 3 and the spiral rotary blade portion 13 constituting the rotation action portion 4 shown in FIG. 6 is reversed. The formed chain rod body 1 is used in combination and arranged vertically.

  The chain element 1 shown in FIG. 6 is centered on the linear member 5 in which the rotary blade 13 is the shaft body 3 by hitting the inclined surface of the rotary blade 13 from the upper opening 14 as shown by the arrow C in FIG. A force that further rotates the chain element 1 by causing the rainwater to flow in a spiral flow along the spiral rotating blade part 13. As a result, the chain element 1 rotates around the wire 5 as shown by the arrow D in FIG.

4 and 5 show an example in which a chain element 1 that rotates in one direction and a chain element 1 that rotates in the opposite direction are alternately arranged up and down by the flow of rainwater. However, it is not necessarily limited to this, and the form in which the chain element 1 rotating in one direction and the chain element 1 rotating in the opposite direction can be arbitrarily selected. .

  Moreover, you may make it a rotational speed of some chain | strand element bodies 1 become slower than the other chain | strand element | child bodies 1 among the some chain | strand element | child bodies 1 rotated by the flowing hydropower of rainwater.

  In this case, for example, as shown in FIG. 7 and FIG. 8, by changing the inclination angle of the spiral rotating blade part 13 constituting the rotation action part 4, the rotation speed due to the action of hydrodynamic force is increased for those having a gentle inclination angle. The fast and steep inclination angle has a slow rotation speed due to the action of hydrodynamic force, which causes the fast rotating chain element 1 and the slower rotating chain element 1 to be mixed in the vertical direction. The chain 2 can move in a variety of ways.

Moreover, in the form of the reference example shown in FIG. 7 and FIG. 8, when the chain rod 2 is configured using a plurality of chain rod bodies 1 that are rotated by flowing hydropower, As shown in the example in which the chain rods 1 having different rotation speeds are combined, the chain rods 2 are mixed in the vertical direction of a plurality of chain rod bodies 1 having the same rotation direction but different rotation speeds. It may be formed.

Moreover, in the said example, the shaft body 3 was comprised with the linear material 5 long to an up-down direction like a wire and a bar, and the example which attached multiple chain element bodies 1 to this linear material 5 at the up-down direction As shown in FIGS. 9 to 11, as shown in FIGS. 9 to 11, a connecting portion 6 is provided on the shaft body 3 on which the chain rod body 1 is rotatably attached, and the upper and lower chain rod bodies 1 are connected by the connecting portion 6. The chain rod 2 in which a plurality of chain rod bodies 1 are arranged in the vertical direction may be configured. 9 to 11, the shaft body 3 provided with the upper or lower connecting portion 6 at either the upper end portion or the lower end portion is loosely inserted into the hole 11 of the central shaft portion 10. The lower or upper connecting portion 6 is attached to the lower end or the upper end. On the upper part of the lower connecting part 6, a fall prevention part 12 for dropping the lower end of the lower end part of the central shaft part 10 is provided. Then, the upper joint portion 6 provided at the upper end portion of the shaft body 3 of the lower chain rod body 1 is connected to the lower joint portion 6 provided at the lower end portion of the shaft body 3 of the upper chain rod body 1. Thus, the chain rod 2 in which a plurality of chain rod bodies 1 are arranged in the vertical direction can be configured.

  In the above example, the chain element 1 is rotated by the flowing water of rainwater. However, the chain element 1 may be rotated by wind power.

FIG. 12 shows a form of the reference example, in which the rotary action part 4 is configured by projecting the rotary blade part 13 on the outer peripheral surface of the cylindrical body 7 of the chain element 1. That is, when the wind blows and the wind strikes the rotating blade portion 13 on the outer peripheral portion of the chain element 1 that is rotatably attached to the shaft body 3, the chain element body 1 rotates. In this embodiment , the chain element 1 rotates if the wind is blowing, whether it is raining or not raining.

  Therefore, when it is raining, if the wind does not blow, the chain element 1 does not rotate like the conventional chain 2. When the wind blows, the chain element 1 differs from the conventional chain 2. It is possible to provide a chain 2 that moves in a variety of ways, such as rotating.

  Also in the case of rotating with this wind force, illustration is omitted, but by selecting the shape of the rotating blade part 13, the rotating direction can be either one direction or the opposite direction, and the rotation speed is different. Can form things.

  Further, in FIG. 13, a rotating blade portion 13 is provided on the outer peripheral surface of the cylindrical body 1 of the chain rod body 1 to form a rotating action portion 4 for rotating the chain rod body 1 by wind, and the cylindrical body 7. This is an example in which a rotating blade portion 13 having a spiral shape as in the above-described embodiment is provided, and the rotating action portion 4 that rotates the chain element 1 by the flowing water force of rainwater is formed.

  In this embodiment, the chain element 1 can be rotated by the flow force of wind power and rainwater. When there is no precipitation but the wind is blowing, the wind is not blowing, but the precipitation, the precipitation and the wind In any case when is blowing, the chain element 1 can be rotated.

Then, these various forms of chain rod bodies 1 are appropriately combined in the vertical direction, and the chain rod bodies 1 that are rotated in the same direction are arranged in the vertical direction in the same manner as in the above-described respective forms to form the chain rod 2 The chain rod 2 is formed by mixing the chain rod bodies 1 having different rotation directions in the vertical direction, or the chain rod body 1 having different rotation speeds is mixed in the vertical direction to form the chain rod 2. Alternatively, the chain rods 1 having different rotation directions and rotation speeds may be mixed in the vertical direction to form the chain rods 2.

In any of the above forms , when the chain rod body 1 is rotated by the flowing water force or wind power of rainwater attached to the shaft body 3 so as to be rotated by the flowing water force or wind force of rainwater. Rotational visual enhancement means 8 for enhancing visual recognition of the rotation of the chain element 1 may be provided.

For example, the rotation visual enhancement means 8 is configured by changing the color or shape of a part of the outer peripheral surface of the chain element 1 from the other part in a different color or shape. In this embodiment , when the chain element 1 rotates, the rotation visual enhancement means 8 that is a part of the color or shape of the outer peripheral surface that is different in the circumferential direction can be visually recognized so as to revolve around the shaft body 3. The rotation of the element body 1 can be visually recognized with more emphasis. In the form of FIGS. 12 and 13, the rotation action part 4 exposed to the outside also serves as the rotation visual enhancement means 8.

  Although not shown in the drawings, the rotation visual enhancement means 8 may be configured by making a part of the outer peripheral surface of the cylindrical body 7 transparent and making the other part opaque. In this case, when the chain element 1 rotates, the transparent portion of the cylindrical body 7 can be visually recognized so as to revolve around the shaft body 3, and the inside of the cylindrical body 7 is intermittently visually recognized from the transparent portion. By doing so, the rotation of the chain element 1 can be visually recognized with more emphasis. In this case, the rotation action part 4 and the spiral flow in the cylinder 7 are seen intermittently.

  Although not shown in the figure, the cylindrical body 7 is entirely transparent, or a transparent portion extending in the circumferential direction is provided to constitute the rotation visual enhancement means 8, and the rotation and spiral flow of the internal rotation action portion 4 is prevented. You may make it visible. In this case, the rotation of the rotation action part 4 can be visually recognized through the transparent cylinder 7 by making the rotation action part 4 opaque.

FIG. 15 shows another embodiment of the present invention for explaining the present invention. In this embodiment , means 19 for floating the chain element body 1 rotatably attached to the shaft body 3 with respect to the shaft body 3 is shown. It is provided. As a means for floating 19, a permanent magnet 20 is provided in which the lower end portion of the chain rod body 1 rotatably inserted in the shaft body 3 and the portion facing the portion of the shaft body 3 facing this have the same polarity. Thus, the means 19 for floating the chain element 1 with respect to the shaft body 3 is configured, and the chain element body 1 is lifted with respect to the shaft body 3 by the repulsive force of the permanent magnet 20 having the same polarity. It is in a state. By making the chain element 1 rotatable in a state where it floats with respect to the shaft body 3 in this way, the chain element body 1 is rotated lightly even when the flowing hydraulic power is small or the wind force is small. be able to.
