Description

Detailed description of the invention

  The present invention relates to a hanging decoration device that is naturally driven by a small movement of air in a room.

  Just as the aurora swaying in the heavens gives a mysterious excitement, the aesthetic that fluctuates irregularly gives the viewer a sense of comfort and healing. Hanging interior decorations are on sale for the purpose of providing such visual effects. FIG. 1 is a simplified view of one of the commercially available products, in which a plurality of colorful paper or plastic decorations reminiscent of a balloon are connected. Although decorations designed with balloons, flowers, birds, fish, abstract shapes, etc. are offered to the market in this way, they remain stably suspended except in places where there is air movement such as air conditioners and passageways. . Even if there is a movement, it is basically a wind chime swinging back and forth or a yajirobei style regular up-and-down swing, so irregular movement in the rotating direction cannot be expected. Fig. 2 shows a product example of a double pendant in which a metal frame is hung with a thread and a decoration is further hung therein, but the inertial mass is large because the outer periphery is surrounded by a heavy metal frame, and Since the center of the wind pressure is not offset, it is not possible to expect the rotation swing due to the slight wind. Each of the above-mentioned products has a design feature, but does not have a function of capturing a breeze and obtaining rotational drive. Because there is no ingenuity in the energy source that gives the ornament a fluctuation in the direction of rotation, it stops immediately without touching it with your hand, opening the window to take in the wind, or hitting the wind of an air conditioner or fan, etc. Easy to be just. Also, when it moves, it moves by the wind from front to back or left and right, or moves up and down regularly in the Yajirobei style. Therefore, the appearance of the design was emphasized so that the atmosphere could be enjoyed, and no structural innovation was made. As disclosed in the present invention, no patent or utility model application relating to the idea of rotating and rotating the decorative body irregularly by storing the rotational torsional energy due to the breeze is not found in the gazette. As an idea for positively driving the interior decoration to rotate irregularly, Japanese Patent Laid-Open Publication No. Hei 8-62351 discloses a table-type rotary decoration that is driven to rotate irregularly by a motor and a permanent magnet. It requires a fixed location and a power source, and is different from the hanging type decoration of the present invention.

Issues that the device is trying to solve

  The challenge is whether it is possible to efficiently capture the movement of minute indoor air, and whether it is possible to make the decoration perform irregular movement with the minute energy.

Means for solving the problem

  Means taken to solve the above-mentioned problem is to suspend a very light wind receiver rotating body with a thread and to hang the wind pressure center of the wind receiver on a thread suspension axis in order to sensitively capture the minute air movement in the room. It is offset from. The captured energy of air movement is stored as torsional rotation energy in the torsional elastic suspending string, and when the wind stops or the direction changes, the wind receiver rotator is slowly reversed while releasing the stored energy. It is to rotate. If a similar wind receiving rotator is hung on the wind receiving rotator in a multi-stage manner with a thread, each of the rotators can perform different complicated rotations or stops due to mutual interference and inertia effects.

Action

  The air in the room where people live is constantly moving, albeit slightly. The rotating decoration device of the present invention moves the decoration by sensitively capturing the slight movement of air. When a lightweight material such as a foamed plastic plate having a thickness of about 1 mm is used as the wind receiving plate, the weight is about several grams and the inertial mass is extremely small. When the decorative rotator incorporating this wind receiving plate is hung with a thread, the decorative rotator is hung with a thread and restrained up and down, but it is also sensitive to minute air movement in the rotation direction. It can react and move lightly. In order to efficiently capture the pressure of the breeze that moves linearly, the above-described lightweight wind receiving plate is incorporated in the rotating body so as to be offset from the suspended rotating shaft. The rotational force due to the breeze is expressed by the product of the effective area of the wind receiving plate and the wind pressure, and the distance between the center of the wind pressure and the rotation axis. Due to this rotational force, the suspension string is twisted and accumulates rotational energy, and when the wind changes, the rotating body returns in the opposite direction to release the energy. When a similar rotating body is suspended further below the wind receiving plate, a difference in the wind contact, a delay in the transmission of rotational force due to the elasticity of the yarn, and a respective inertial mass effect cause a time delay in starting each rotating body. Performs a slower and more irregular rotation.

  Embodiment 1 of the present invention will be described with reference to the front view of FIG. A hanging string 1a has an upper end fixed to a ceiling or other indoor structure, and a wind receiving rotating body 2 is moored to a lower end at a balance center 2a. The wind receiving rotator 2 has, on one side, a vertical wind receiving portion 2c made of a thin sheet of foamed plastic and is incorporated with an offset, and the arm 2b extends in the opposite direction. The air receiving part 2c is designed as a decoration. The arm 2b is for maintaining the weight balance with the wind receiving portion 2c, and is preferably shaped so as not to easily receive the wind pressure. A plate having the same shape as the wind receiving portion 2c is made horizontal or a slight twist angle. It may be a winged one with. Another rotating body 3 is suspended below the balance center 2a of the wind receiving rotating body 2 by a hanging string 1b. The lower end of the hanging thread 1b anchors the arm 3b of the rotating body 3 at the balance center 3a. Decorative portions 3c are attached to both outer ends of the arm 3b, respectively. In FIG. 3, 3c is circular, but there are ornaments such as flowers, birds, fish, and abstract shapes, and these may be fixed to the arm 3b or hung with a thread. In a second embodiment shown in FIG. 4, two wind receiving rotating bodies 2 are suspended in a two-stage manner. Although the present embodiment has a two-stage structure, it can be practiced with three or more stages. Some of them can be specially designed for decoration. In the third embodiment shown in FIG. 5, the wind receiving rotating body 2 is changed to a loop-shaped lightweight frame, and the wind receiving portion 2c is incorporated on one side of the frame 2d. The balance center 2a on the upper side of the frame 2d is moored at the lower end of the hanging thread 1a. The rotating body 3 is hung downward from the center 2a with a hanging thread 1b. The rotator 3 can have a slower motion when the inertial mass is larger than that of the wind receiver rotator 2. The rotating body 3 is moored around the balance center 3a of the arm 3b with the hanging string 1b. Both the wind receiver rotating body 2 and the rotating body 3 including the frame are objects of decorative design. In the embodiment, the suspension is performed by the thread, but a twistable flat cord or a coil material may be used.

  In the first, second and third embodiments, another rotating body is suspended below the wind receiving rotator. However, the wind receiving rotator is disposed at the lowermost end, and the other rotating body is moored in the middle of the hanging thread. Can achieve a similar effect.

  FIG. 6 shows a fourth embodiment, in which a baffle 4b is attached to one end of an arm 4a of a decoration rotating body 4, and a decoration 4c is incorporated on the opposite side of the arm. The decorative part 4c may be fixed to or suspended from the arm 4a. When a rotation direction inclination angle is given to the wind receiving portion 4b, the air receiving portion 4b can be rotated by receiving a descending airflow near a wall, solar radiation heat, or a rising airflow of a heater. Although the start-up is somewhat slow due to the integration and weight, it is possible to obtain a slow irregular rotation swing.

The effect of the invention

  The hanging rotary decoration device according to the present invention has a simple structure, but captures the movement of air very sensitively by the wind receiver rotating body with the wind pressure center offset, and stores this energy as torsional rotation energy on the hanging thread or Release and convert to rotational movement of the ornament. The movement of the decoration rotator is very slow and has irregular changes, giving the viewer a resting effect due to fluctuations.
