Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD OF THE INVENTION The present invention not only generates rubbing vibration due to rotational movement but also generates pile striking vibration due to reciprocating movement. In particular, even if a composite wavelength due to vibration or sound is transmitted to the ground, The present invention relates to a windshield integrated propeller device that avoids staggering and has a structure that not only drives away the windshield but also performs a completely new operation in which the blade portion also functions as the windshield, while keeping the cost low.

[0002]

[Prior art] Conventionally, the structure that turns the propeller in the wind direction and rotates it is equipped with a mechanism for automatically propelling the propeller in the wind direction except for the vertical axis type wind turbine in the case of a large wind turbine. Or, in the case of a small and simple wind turbine, the propeller was turned to the wind direction by the wind vane installed vertically, but the wind vane was attached to all wind turbines with a simpler structure.

However, the structure in which these wind direction plates are attached is one in which a propeller is attached to both ends of a horizontal rod (the first rod of the claim of the present application) and a wind direction plate is attached to the other side. Was taken,
In order to turn the propeller in the actual wind direction, the weight on the wind direction plate side must be heavier than the center of gravity.For example, if the propeller side is heavier than the wind direction plate side, the wind direction plate does not work well and the wind blows. It had a problem that the propeller could not be directed in the direction of the wind, and in terms of balance, the wind vane was large enough and the weight on the wind vane side had to be heavier, which was inefficient when combined with the cost of the propeller. . However, on the contrary, if the wind direction plate is not attached, the propeller does not point accurately in the wind direction, resulting in poor efficiency.

[0004]

Therefore, in order to solve this, the applicant of the present application filed an application for "propeller device with integrated wind deflector for avoiding mogura" on January 23, 1992. Although it was excellent in performance, a structure that could further reduce costs was necessary for commercialization. Further, in the application, the pipe to be the second rod is fixed to the end of the first rod with a nail or a screw to rotate the second shaft to generate a rubbing noise. Due to the small friction portion, there was a problem that sufficient rubbing noise was not generated.

[0005]

Therefore, according to the present invention, although the propeller is made to have the function of the wind direction plate, structurally, the tip end portion of the rotating second shaft core rubs and vibrates due to the movement of the propeller. And a pile vibration are generated, and the structure thereof will be described below in detail with reference to the drawings.

The rod a is further moved from the base column 2 through a first shaft core 1b which makes a substantially horizontal circular motion, and a second which makes a substantially vertical rotation motion 10.
As the structure having the shaft core 2b, the blade part 1 is finally connected to the tip from the second rod 2a, and the second rod 2a is formed with the hole forming body 3 having the hole 4 formed therein. A second shaft core 2b is formed by penetrating a nail, a screw 7 or the like in a state in which there is play / clearance in the hole 4 and the hole forming body 3 makes a reciprocating motion 9 between the play / clearance. The third axis 3
As a structure that also functions as b, while the blade portion 1 also functions as a wind direction plate, the vibration between the second shaft core 2b and the third shaft core 3b causes at least reciprocating motion 9 and rotary motion 10 to vibrate. It has a structure to generate a sound.

Further, the hole forming body 3 is constituted as the third rod 3a, the second rod 2a is constituted by the pipe body 5, and the pipe body 5 is the second rod.
After penetrating the inside of the pipe with a nail, a screw 7 or the like to be the shaft core 2b, the pipe body 5 itself is again penetrated into the hole 4 of the hole forming body 3,
At least a part of the hole portion 4 and the pipe body 5 is in line contact 8 with both of them, and the rotational force transmission for directly transmitting the rotational movement 10 of the hole forming body 3 to the pipe body 5 serving as the second axis 2b. As the structure, the hole forming body 3 may move in the reciprocating direction 9 depending on the play / clearance to function as the third shaft core 3b.

Further, the movement of the third shaft core 3b is not limited to the reciprocating movement 9 by the third rod 3a, but also has a structure in which the line contact 8 between the hole forming body 3 and the tube body 5 has rattling. A swinging circular movement 11 due to the rattling of the movement of the third axis 3b.
As a structure capable of simultaneously performing both, the swinging circular motion 1 in which the blade portion 1 moves in the wind direction along with the motion as the third axis 3b due to the rattling structure different from the play / clearance
Good as one structure

[0009]

[Operation] As a minimum condition for the characteristics of the propeller of the present invention, at least the first shaft core 1b and the second shaft core 2
b, the third axial core 3b serves as a total of three axial cores. In addition to this, the movement itself of the blade portion 1 also has the function of the wind vane of the conventional weathercock. In addition, according to the first aspect, the hole forming body 3 has a rotational movement 10
By simultaneously performing the reciprocating motion 9 and the reciprocating motion 9, a structure as shown in FIG. 3 is obtained. Further, in claim 2, while the tube body 5 serving as the second rod 2a is rotationally moved to form the second shaft core 2b, the reciprocating motion 9 is simultaneously performed to the hole forming body 3 serving as the third rod 3a. Thus, the third shaft core 3b is used, and the structure is as shown in FIG. In the third aspect, as in the second aspect, the tubular body 5 is rotationally moved 10 to form the second shaft core 2b, but the hole forming body 3 of the third rod 3a has a play
A reciprocating motion 9 due to a gap and a new circular motion 11 in which the blade part swings in the wind direction are provided by rattling the line contact 8 between the tube body 5 and the hole forming body 3 in the twisting direction. Also has a structure that can be used as the third shaft core at the same time, and in this case, it operates exactly as shown in FIG.

By the way, in order to perform the reciprocating motion 9 of the present invention, the shape of the hole 4 of the hole forming body 3 is just formed to be long and thin so as to have a play / clearance only in a specific direction. By supporting the pipe body 5 such as a nail or a screw 7 or a pipe by penetrating it, sound and vibration are generated when the propeller rotates due to wind.
This is because the hole forming body 3 naturally falls by the amount of play due to the weight of itself and the blade portion 1 when the state of the figure is reached, and when the propeller rotates, it falls, rotates, falls, and rotates, resulting in This is a simple device for agricultural work that is effective as a device that tries to drive away by generating vibrations and sounds that birds and beasts and insects dislike, and that drives the pile and hammer effect of the blade part 1 to drive away creatures with sound and vibration. It is also a very effective device. In addition to this effect, according to the present invention, the support portion penetrating the hole 4 is rubbed by the rotation of the hole forming body 3 to generate vibration and sound. In this case, a structure for generating rubbing vibration is generated. With regard to the above, the claim 1 is slightly different from the rest of the claims. In contrast to claim 1, the reciprocating motion 9 and the rotating motion 10 simultaneously generate rubbing vibration in the hole 4 itself of the hole forming body 3. Claims 2 and 3 differ in that the rotary motion 10 is generated by the tubular body 5, and as a result, the latter tubular body 5 contact is larger because the contact area becomes a line and becomes larger. Although the vibration can be generated, in this respect, the one previously filed by the applicant of the present application has a drawback that the rubbing vibration cannot be largely generated because the area of the contacting portion is small due to the rotary motion.

In addition, according to the present invention, the pipe 5 is passed through the hole 4 of the hole forming body 3 so that the hole forming body 3 is rotated.
In order to effectively transmit to the hole portion 4 and the tube body 5, at least a part of them makes a line contact 8 with each other, and the line contact 8 of the sliding portion due to this reciprocating motion 9 is used effectively for rotation. This is a transmission structure for transmitting a rotational force to the tube body 5 by performing the function of a screwdriver in the direction. By the way, such a rotational force transmitting structure by the line contact 8 may use any number of contact lines to make contact with the tubular body 5. Therefore, the contact line may be transmitted to the rotational force at one place.
Further, the line to be contacted may not be a straight line but may be a curved line, or the contact line may be a broken line such as a state where a wrench is fitted into a nut and rotated. Further, by winding a thin plate to form an O-ring, the hole forming body 3 can be obtained.
The material may be punched in a stretched state when punching the central hole portion 4 with a press, and the contact surface between the central hole portion 4 and the tubular body 5 that makes the line contact 8 may be expanded from the line to the surface.

By the way, the shape of the hole 4 formed in all the claims of the present invention is not limited to the elongated shape as shown in the drawing, but may be a star shape, a semicircle, a triangle or the like.

Further, according to the third aspect, the line contact 8 between the hole forming body 3 and the tube body 5 is provided with backlash so that the movement of the third shaft core 3b causes a swing circle due to the backlash. When the wind blows, as shown in FIG. 2, the rattling first causes the blade portion 1 to react in the wind direction and shake the head, and the first rod is pressed by the wind. The propeller rotates only when the lathe 1a is moved in the leeward direction from the base column 2 in a circular orbit to finally swing the airframe in the wind direction, and then the airframe coincides with the wind direction. In other words, this device does not require the wind direction plate
Can also function as a wind vane, and can function without losing the wind vane like a conventional weathercock. In this way, the important point that this structure does not exist in the conventional propeller is that it works to orient the vane portion 1 in the wind direction as in the previous application. In order to receive more wind, this operation is similar to that of the wind vane that has been conventionally used.

【Example】

FIG. 1 is a partial cross-sectional perspective view showing a first embodiment of the present invention, and FIGS. A to C are parts proposed by further changing the hole forming body and the vicinity of the pipe body of the embodiment. It is a perspective view.
Although this drawing has the characteristics of claim 2, it can easily function as claim 3 by making the swinging circular movement 11 with rattling. The greatest feature of this device when compared with the conventional one is that the blade portion 1 rotates rearward with respect to the wind direction, that the minimum required number of the axis b is one more, and that the wind direction The difference is that no plate is required. The vibration sound generated by this is not only the conventional rubbing vibration due to the rotation, but also the play is provided on the third rod 3a, so that when the blade portion 1 rotates, it will be "clicked" or "clicked" due to the natural fall or centrifugal force due to its own weight. Generate pile driving vibration.
However, in the case of this figure, the wind direction plate may be intentionally formed near the blade portion 1, and in this case, the main function of directing the airframe in the wind direction is that the blade portion 1 also functions as the wind direction plate. Moreover, even if the wind direction plate is intentionally provided, the area is small, and when viewed from the vibrating surface, the first rod 1 is provided by the center of gravity on one side.
a itself sways up and down, and the vibration to the base 2 causes the first rod 1a to move.
It also conveys the low vibration of the rock to the ground.

Further, among the structures of the tubular body 5 and the hole forming body 3 of the second rod 2a, in particular in FIG. 1, the tubular body 5 is characterized in that a surface for line contact 8 is formed by scraping. . Further, the characteristic of FIG. A is that the tube body 5 is crushed to form the line contact 8 surface, so that the hole penetrating the nail / screw 7 is not cylindrical as shown in FIG. 1 and the rotation is not stable. There are some. Further, the hole 4 is connected to the outside of the hole forming body 3 and is not a perfect hole. Further, the hole forming body 3 may directly attach the blade 1, or when the hole forming body 3 rotates, the reciprocating motion 9 causes the washer 6 to move up and down with "click" and "click" to make a sound. Anything is fine. Further, as shown in Fig. B, a fine rod material such as a wire may be bent to be processed to form the hole forming body 3 as shown in the drawing, or the pipe body 5 may be scraped by scraping the line contact 8 portion. What penetrated 5 may be sufficient. Alternatively, as shown in Fig. C, an umbrella nail may be used for the nail / screw 7 so that the hole forming body 3 is less likely to come off from the line contact 8 portion of the pipe body 5, or the pipe body 5 has a corner such as a square. The square tube 5 may have a round hole in the center or a square hole as shown in the figure. If you use a thick one, you can rotate it smoothly.

[0016]

FIG. 2 is a plan view showing a motion state of the first embodiment of the present invention. With the feature of claim 3, the movement of the third shaft core 3b is not limited to the reciprocating movement 9 by the third rod 3a, and the line contact 8 between the hole forming body 3 and the pipe body 5 is rattled. Yes, a swinging circular movement 11 due to the rattling of the movement of the third axis 3b.
In addition to the original reciprocating motion 9 as the third shaft core 3b due to the play and the gap, it is possible to simultaneously perform a swinging circular motion 11 in which the blade portion 1 moves in the wind direction. As a result, for example, when the wind blows from the lateral direction of the airframe, the plurality of blade portions 1 having a wind-cutting angle shake the head as shown in FIG. It works by moving the first rod 1a downwind from the base pillar 2 in a circular orbit while being pressed by the wind and finally swinging the aircraft in the wind direction, and then only when the aircraft matches the wind direction. The propeller will rotate. In other words, in this device, even if the wind direction plate is not necessary, the blade portion 1 can sufficiently function as the wind direction plate.
Unlike the conventional weathercock, if you do not remove the wind direction plate, you will not stop swinging. In this way, the important point that this structure does not exist in the conventional propeller is that it works to orient the vane portion 1 in the wind direction as in the previous application. In order to receive more wind, this operation is similar to that of the wind vane that has been conventionally used.

[0017]

FIG. 3 is a partial perspective view showing a second embodiment of the present invention. The present invention has the features of claim 1 and is characterized in that the nail 4 and the screw 7 are directly passed through the hole 4 of the hole forming body 3.
Therefore, unlike the first embodiment in that the hole forming body 3 performs the function of the second rod 2a, the second shaft core 2b performs the rotary movement 10 and the reciprocating movement 9 simultaneously. Become. However, this structure has a problem that the rubbing vibration and the noise are not significantly generated because the contact portion when the rotary motion 10 is performed is smaller than that in the first embodiment. Therefore, as a solution to this, as shown in the figure, the pipe body 5 is not penetrated into the hole portion 4 and the limbs are projected from the pipe body 5 while passing through like the washer 6 so that the limb can be fitted into the hole portion 4 or the hole portion. The hole forming body 3 is provided by holding the forming body 3 from the outside so as to have a catch.
The rotation can be transmitted to the tube body 5 and rotated to generate rubbing vibration and sound.

By the way, the use method of the present invention can be applied not only to a weathercock having a simple structure, but also to generate a wave due to a wind noise caused by the rotation of the blade portion 1, a rotational friction sound of a shaft, and a second noise.
The tapping sound caused by the play between the rod 2a and the third rod 3a, the collision sound of the washer 6 and the like can also be used for repelling / dispelling birds and beasts and insects. Further, according to the present invention, since the blade portion 1 rotates rearward of the first axis, even if a tail fin such as a kite-foot of a kite is attached to the blade portion 1, the tail fin does not entangle with the device. Not only that, the tail fin can be pulled by the wind, so that the blade portion 1 can be rotated even in a weak wind, and the appearance of the tail fin flowing in the wind can scare birds and the like.

[0019]

The present invention eliminates the need for a wind direction plate, which has always been necessary in the past, and allows the blade portion to also serve as a wind direction plate.
Since the blade can be rotated by changing the direction of the propeller in various wind directions, even when it is used for a simple weathercock, basically the sound and vibration generated by the present invention are the same as the conventional propeller. The present invention not only generates rubbing vibrations and sounds between each other, but in addition to the rubbing vibrations and sounds, the present invention is because of the pile driving vibrations and sounds due to the play of the third rod, and further according to claim 3, the swinging circular motion. It is possible to generate various vibration wavelengths by utilizing the rattling. Further, the vibration or sound generated near the propeller may be transmitted to the base pillar to regenerate the rubbing sound of metal or wood or the collision sound in the ground to enhance the effect of purging away the wobble. Further, the present invention generates waves by wind noise caused by rotation of the blades, rotational friction noise of the shaft, tapping noise caused by play of the third rod, and rubbing noise between metals.
It is possible to use ultrasonic waves caused by vibrations not only to make noises due to collisions of washers and the like, but also to repel and dispel birds and beasts and insects. Moreover,
Even if you attach a tail fin such as a kite foot of a kite to the rotating blade part, not only the tail fin does not entangle with the device, but also the tail fin is pulled by the wind and the blade part can be rotated even in a weak wind On top of that, you can scare birds with the tail fin flowing in the wind.
