Description

  The present invention relates to an object.

  As is well known, there are a wide variety of objects installed in gardens, such as agates and natural stones. Among them, the most prestigious are those that add dynamic expressions in static gardens. Often.

  Intimidation is a bamboo cylinder that is open at one end and closed at the other end, and is fixed to the base. The center of gravity of the bamboo cylinder is above the fulcrum and positioned closer to the other end. It has been. Accordingly, the bamboo cylinder is inclined so as to lower the other end unless an external force is applied. When water is poured from the opening of the bamboo cylinder, a predetermined amount of water accumulates in the bamboo cylinder, so that the bamboo cylinder is inclined to lower one end side by the weight of the water, and the water in the bamboo cylinder is discharged from the opening. Subsequently, when the water in the bamboo cylinder is discharged, the bamboo cylinder loses its weight and is inclined to lower the other end side again, and begins to accumulate water in the bamboo cylinder. Note that threatening repeats the series of operations periodically by keeping the amount of water flowing into the bamboo cylinder constant.

  As an example utilizing the principle of intimidation, in Patent Document 1 described later, in an automatic water supply device that supplies water to a potted plant at a fixed interval, a predetermined amount of the water or the like is stored, and the water or the like is stored. A tank having a pouring hole that pours out in small quantities, and water that has been poured out from the pouring hole, and when the water accumulates a certain amount or more, it swings and drains the accumulated water. The provided potted plant automatic water supply apparatus is disclosed.

  By the way, in the water supply device using the principle of the threat or the threat, when discharging the water accumulated in the bamboo cylinder (tank), the other end side (rear side) from the support shaft in the bamboo cylinder. Since the accumulated water moves to one end side (front side) at once, the tilting action to lower one end side is quick, and at this time, all the water in the bamboo cylinder is discharged at once, so one end side becomes lighter suddenly. As a result, the tilting operation to lower the other end side (rear side) also becomes quick and does not swing gently.

Accordingly, the present inventors utilizes the principle of the InoTakeshi Mr and as technical problem to obtain a object to represent the motion Do was new that can not be represented in the boar threatened, the realization As a result, as a result of repeated trial and error experiments, in an object having a base, a support shaft provided on the base, and a swinging body fixed to the support shaft, a cavity extending from one end to the swinging body In addition, an inlet for flowing liquid into the cavity is provided in the cavity, and an outlet for discharging the liquid from the cavity is provided on one end side of the inlet, and the center of gravity of the oscillator is poured into the cavity. In a state where the oscillator is positioned closer to the other end side than the support shaft, the liquid is discharged from the cavity in a state where the swinging body is inclined to lower one end side by the weight of the liquid flowing into the cavity from the inlet. The discharge port is located and the rocking body is the most The knowledge that the rocking body can be rocked gently if a part of the liquid in the cavity stays in the cavity without being discharged from the discharge port in a state of being inclined to lower the side. To achieve the above technical problem.

  The technical problem can be solved by the present invention as follows.

That is, an object according to the present invention is an object having a base, a support shaft provided on the base, and an oscillating body fixed to the support shaft, and the oscillating body has a cavity extending from one end side. The inlet is formed in the cavity, and an outlet for discharging the liquid from the cavity is provided on one end side of the inlet, and the outlet is an oscillating body. The center of gravity of the oscillating body is located closer to the other end side than the support shaft when no liquid is poured into the cavity. The discharge port is positioned so as to discharge the liquid from the cavity in a state where the swinging body is inclined so as to lower one end side by the weight of the liquid flowing into the cavity, so that the swinging body lowers the one end side most. One of the liquids in the cavity in the tilted state There are those remain within the cavity without being discharged from the discharge port.

  Further, according to the present invention, in the object, the tip of the cylindrical body is inclined so as to be lowered from the other end side to the one end side.

  According to the present invention, the oscillating body is formed with a cavity extending from one end side, the inflow port for flowing liquid into the cavity is provided in the cavity, and the discharge port for discharging the liquid from the inside of the cavity is provided at one end side with respect to the inflow port. The center of gravity of the oscillating body is positioned closer to the other end side than the support shaft when no liquid is poured into the cavity, and the oscillating body lowers one end side by the weight of the liquid flowing into the cavity from the inlet. In the state inclined to the position, the discharge port is positioned so as to discharge the liquid from the inside of the cavity, and in the state where the rocking body is inclined so as to lower the one end side, a part of the liquid in the cavity is not discharged from the discharge port. Since it is configured to remain in the cavity, when the oscillator is tilted so as to lower one end side and tilted so as to lower the other end side, part of the liquid accumulated in the cavity is hollow. Without being discharged from within Exists for, tilts it by the weight of the one end side of the rocking body is relaxed reduced as slowly the other end is lowered. In addition, when the swinging body is tilted so as to lower the other end side, it is tilted so that the one end side gradually falls depending on the weight of the liquid gradually accumulated in the cavity. . Therefore, the oscillating body can express a new movement that is not intimidating that it repeatedly oscillates at a slow cycle.

  Therefore, it can be said that the industrial applicability of the present invention is very high.

  Embodiments of the present invention will be described below.

  Embodiment 1 FIG.

  As shown in FIGS. 1 and 2, the object 1 according to the present embodiment has a base 3 standing upright with respect to the installation surface 2 and an installation surface 2 provided at the upper end of the base 3. An object having a support shaft 4 extending in the horizontal direction and a rectangular rocking body 5 fixed to the support shaft 4.

  The swinging body 5 is formed with a recess 6 that is recessed upward from the lower surface, and the support shaft 4 is stretched over both inner side surfaces of the recess 6. Thereby, the rocking | swiveling body 5 can rock | fluctuate in the shape of a seesaw about the spindle 4 as a rotating shaft.

  Further, the oscillator 5 has a cavity 8 formed in a portion located on the one end 7 side of the support shaft 4, and an inlet for allowing water to flow into the cavity 8 on the support shaft 4 side. 9 is formed, and a discharge port 10 for discharging water from the cavity 8 is formed so as to be positioned closer to the one end 7 than the inflow port 9.

  The inflow port 9 is connected to the recess 6 through the through hole 11. The tip of the hose 12 passed through the cylindrical base 3 is connected to the inlet 9 through the through hole 11.

  The discharge port 10 is formed by the upper end of a pipe 14 that protrudes into the cavity 8 from an opening 13 formed in the bottom surface of the cavity 8. The discharge port 10 is disposed in the cavity 8 so as to discharge the liquid from the cavity 8 in a state where the rocking body 5 is inclined so as to lower the one end 7 side by the weight of the liquid flowing into the cavity 8 from the inflow port 9. Is positioned at a predetermined height.

  The center of gravity of the oscillating body 5 is positioned closer to the other end 15 than the support shaft 4 when no liquid is flowing into the cavity 8. The center of gravity of the oscillating body 5 moves so as to straddle the portion located below the support shaft 4 in a state where the oscillating body 5 is kept horizontal by putting liquid into and out of the cavity 8.

  Next, the operation of the object according to the present embodiment will be described.

  First, as shown in FIG. 3A, in a state where no liquid is flowing into the cavity 8, the center of gravity of the oscillator 5 is located on the other end 15 side of the support shaft 4, and therefore the oscillator 5 Is inclined so that the other end 15 side is lowered with the support shaft 4 as a fulcrum.

  Next, when the liquid is poured into the hose 12 passing through the base 3 and the liquid is poured into the cavity 8 from the inlet 9, the liquid 16 accumulates in the cavity 8 and shakes as shown in FIG. The weight on the one end 7 side of the moving body 5 increases and the one end 7 side gradually begins to fall. The liquid 16 flowing into the cavity 8 is always kept flowing from the inlet 9 at a constant flow rate. When the liquid 16 accumulated in the cavity 8 reaches a predetermined amount, the center of gravity of the oscillating body 5 moves toward the one end 7 with respect to the support shaft 4, so that the oscillating body 5 is lowered on the one end 7 side with the support shaft 4 as a fulcrum. It will be in a state inclined like this. At this time, since the rocking body 5 is tilted so as to lower the one end 7 side, the liquid 16 accumulated in the cavity 8 moves to the one end 7 side in the cavity 8, so that the rocking body 5 further lowers the one end 7 side. It will be in a state inclined to.

  Next, when the oscillating body 5 is tilted so as to lower the one end 7 side to some extent, the discharge port 10 is positioned below the water surface of the liquid 16 accumulated in the cavity 8 as shown in FIG. The liquid 16 accumulated in the cavity 8 starts to be discharged. When the liquid 16 accumulated in the cavity 8 is discharged to some extent, the other end 15 side becomes heavier than the one end 7 side of the oscillating body 5 as shown in FIG. Tilt starts so that the other end 15 side is lowered with 4 as a fulcrum. At this time, a part of the liquid 16 accumulated in the cavity 8 is maintained in the cavity 8 and the liquid 16 continues to flow into the cavity 8 from the inlet 9. The decrease in the weight is mitigated, and the oscillating body 5 shifts from a state in which the one end 7 side is gently lowered to a state in which the other end 15 side is inclined.

  Since a constant flow rate of liquid 16 continues to flow into the cavity 8 from the inlet 9, as shown in FIG. 3E, the rocking body 5 is tilted so as to lower the other end 15 side to some extent. Thus, the one end 7 side of the rocking body 5 becomes heavier than the other end 15 side due to the weight of the liquid 16 accumulated in the cavity 8, and the rocking body 5 is again tilted so as to gently lower the other end 15 side. Transition to a tilted state with the side lowered.

  Thereafter, by repeating the operations of FIGS. 3B to 3E, the oscillating body 5 performs the oscillating operation gently.

  In the present embodiment, the inlet 9 is provided below the cavity 8, but the inlet 9 may be provided above the cavity 8.

  Further, the pipe in the present embodiment is not particularly limited as long as the liquid can pass therethrough, and the cross-sectional shape may be circular or polygonal.

  In the present embodiment, since the discharge port 10 is formed by the pipe 14, the length of the pipe 14 protruding into the cavity 8 and the inner diameter of the tip of the pipe 14 are adjusted to discharge from the cavity 8. The flow rate of the liquid 16 can be easily adjusted.

  Embodiment 2. FIG.

  The present embodiment is a modification of the oscillator 5 in the above embodiment.

  Modification 1: In the oscillating body 5 in this modification, as shown in FIG. 4, the discharge port 10 divides the inside of the cavity 8 into two parts by the support shaft 4 side and the one end 7 side, leaving the cavity 8 above. It is formed by providing a dam wall 17 and opening a bottom surface located closer to one end 7 than the dam wall 18. Therefore, the discharge port 10 is formed at a high position of the cavity 8.

  Also in this modification, the same effect as the first embodiment can be obtained.

  Modification 2: In the oscillating body 5 in this modification, as shown in FIG. 5, the discharge port 10 is formed by a pipe 14 that protrudes into the cavity 8 from an opening formed in the bottom surface of the cavity 8. The tip of 14 projecting toward the cavity 8 is inclined and cut so as to descend from the support shaft 4 side to the one end 7 side.

  According to this modification, the tip of the pipe 14 forming the discharge port 10 is formed so as to be inclined from the support shaft 4 side (the other end 15 side) to the one end 7 side. As shown in FIG. 6B, when the rocking body 5 is inclined so as to lower the other end 15 side, more liquid can be held in the cavity 8. As shown in FIG. When the oscillating body 5 is inclined so as to lower the one end 7 side, more liquid 16 can be discharged from the discharge port 10.

  Also in this modification, the same effect as the first embodiment can be obtained.

  In the present invention, the liquid flowing into the cavity is preferably water, but may be other than water as long as it flows.
