Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a technology for adding visual aesthetics by using a blowing motion of a handheld fan and a fan for the purpose of seeking coolness.

[0002]

[Prior art]

 Fans and fans are tools for the function of sending wind, but there is no suggestion to add another function to this function. For example, when the scent of perfume etc. accompanies the wind, or when the cylindrical handle of the fan is rotated between the palms of both hands and rotated, the afterimage of the human eye causes a merged picture on the front and back to appear. There is an example of appending Although it is useful from the viewpoint of efficient use of energy and the like to add another positive function using a mechanism that reveals the original function, it is almost impossible for fans and fans. I did not make a suggestion.

[0003] In view of the above, it can be said that the fan and the fan are extremely delayed in terms of actively adding another function using the function of the mechanism of sending the wind. One of the specific tasks is to add visual value in addition to the air blowing function, which is the function of cooling the skin by air blowing, which is the purpose of fan and fan. It can be said that it is rare.

[0004]

[Problems to be solved by the invention]

 The function of a fan or fan (hereinafter simply referred to as a fan, including a fan) is classified as tactile in terms of human senses (tactile, visual, auditory, olfactory, and taste). It is the pleasure of being hit by the wind, and the resulting heat transfer from the skin and the release of heat from the skin due to latent heat of vaporization. The inventor wondered if this could add a visual aesthetic to this.

[0005]

[Means for Solving the Problems] As a result of intensive studies, the inventor has come up with the following invention. In other words, the fan is a fan in which a plurality of light emitting diode element dot rows are attached along an arbitrary vertical direction of the blade section. This is an inventor of the aerial image persistence type fan, in which characters, symbols and figures by the lit dots of the dot row appear as if they appear in the air due to the afterimage phenomenon.

[0006] Furthermore, a character, a symbol, or a figure that appears on the trajectory of the blowing air due to the visual afterimage phenomenon is retroactively displayed on the return path at approximately the same position as the afterimage of the trajectory of the outward path. It is a device of Shikindangi.

In addition, there is provided an aerial image persistence fan, wherein a plurality of rows of light emitting diode elements are provided. Further, the invention provides a device for displaying aerial image sticking-out fans, in which a plurality of rows of dot groups of light emitting diode elements are provided, and the individual dots are arranged in a staggered manner.

[0008]

[Embodiment of the invention]

 FIG. 1 is a schematic perspective view showing an example of the fan of the present invention. Reference numeral 17 in FIG. 1 denotes a blade that generates wind when it is blown by a fan. Reference numeral 19 in FIG. 1 denotes a dot-like LED element row attached along the longitudinal direction of the blade portion of the fan. The LED element is an abbreviation for a light emitting diode (Light Emitting Diode) element.

When the LED element array 19 is viewed from 23 directions, each of the LED elements 26 (shown by a small circle and a small square surrounding it) in the LED element array as shown in FIG. In this case, there are 16 LED elements. Reference numeral 18 in FIG. 1 denotes a handle portion of the fan which is gripped by hand, and shows a switch, an electronic circuit portion 20 and a AAA battery 21 incorporated therein.

FIG. 2 shows a schematic view of a light emitting surface of an LED element row and an example of a position along an elapsed time in a case where the light emitting surface is attached to a fan as shown in FIG. Reference numeral 19 in FIG. 2 denotes an LED element row composed of 16 LED elements, and FIG. 2 denotes a position of the LED element row 19 with the lapse of time when the LED element row is attached to the wings of a fan and made to move. Only the small circular portions of the element 19 are shown. In FIG. 27, white circles indicate non-lighted LED elements, and black circles indicate lighted LEDs.

An LED element is an element based on the principle that when a voltage is applied to both ends of a pn junction diode in the forward direction, energy when electrons and holes are coupled is emitted as light. Used for light-emitting elements.

The LED element referred to in the present invention refers to an LED component including a transparent synthetic resin casing that protects the LED itself and efficiently extracts emitted light. The outer shape of a single LED element is a square or a rectangle having a side of about 1 to 5 mm in a plane direction, or a circle having a diameter of about 1 to 5 mm, and a height of about 1 to 5 mm including a lens part as necessary. It is. Therefore, when these are arranged in a straight line or the like, a dot-shaped row is obtained. The emitted color of the LED elements in a dot-shaped row (referred to as an LED element row) by the LED elements includes an arbitrary hue, and the hue may be an LED emission color or a color of a transparent synthetic resin. Good.

An LED emits light when one of the two poles of a semiconductor pn junction is applied with an appropriate forward voltage. Therefore, one LED element can control “lighting” and “non-lighting” by “applying” and “not applying” the forward voltage.

Another feature of LED light emission is that there is almost no time lag in the relationship between ON / OFF (closed / open) of an applied voltage, light emission, and light emission stop. At the level where the afterimage of human vision is about 1/10 second, incandescent lamps and discharge lamps take several times longer from turning on the electric power to emitting light, and conversely, from turning off the light to stopping the light emission, and the time lag is increased. Extremely large. On the other hand, in the case of LED light emission, only a few tenths to a few hundredths of the human visual afterimage time is required from the voltage ON to the light emission and from the OFF to the light emission stop. The level of afterimage time is equivalent to no time lag.

[0015] The dot row of the LED element is rotated as a diameter or radius as a diameter or a radius, and the passing deflection angle position of the dot row and the emission of each individual dot during the movement are synchronized (synchronized), and the character is made using the afterimage phenomenon. There has been an afterimage revealing method in which images and figures appear. For example, a dot-shaped array of LED elements is arranged on a rotating rod, and the LED array is rotated at a constant speed by a synchronous motor controlled by a clock signal of a digital control mechanism. An example is a clock in which the light emission form of each dot is synchronized so that the dial, short hand, long hand, second hand, digital date, etc. of the clock appear as a still image or a moving image due to the afterimage manifestation phenomenon.

Such a conventional technique requires a rotating body of a digitally controlled synchronous motor for the purpose of only obtaining an image image, and requires a pass deflection angle position of a dot group of light emitting diode elements and a dot of each dot. Since characters and figures are displayed by synchronizing light emission, there are defects such as an increase in cost.

[0017] The present invention, in addition to the function of sending the wind with a fan, as a means of adding visual interest without substantially impairing the original function, by using LED elements and its simple control mechanism, It adds visual added value.

FIG. 3 shows an example of a block diagram of the digital electronic circuit unit according to the present invention. A thick line connecting each block or component symbol indicates a flow of data and control, and a thin line indicates a power supply path. In FIG. 3, 35 is a digital controller with a built-in clock signal, 36 is a memory, 37 senses the fan's fanning motion, and is OFF when stationary, ON when fanning, and reversing reciprocating motion. Is a sensor that consists of a transducer that converts this into an electrical signal.

In FIG. 3, reference numeral 19 denotes an LED element array, 38 denotes an output device, and 39 denotes an electric wire for applying a voltage for lighting each LED. Reference numeral 40 denotes a battery, and 41 denotes a switch. 42 is an input device to the memory 36.

Even when the switch 41 is turned on, the electric signal to the control unit is “stopped” unless the sensor 37 detects the movement while the fan is stationary. If the fan motion is started by hand, the sensor 37 detects the movement of the fan, and the signal to the controller becomes “operation”. The control unit fetches the signal from the memory 36 in accordance with the pulse order of the clock signal, and the control unit assembles a signal for displaying the afterimage of a character, a symbol or a figure based on the signal, sends a command signal to the output device, The output device turns ON / OFF the voltage application to each LED element in the LED element row according to the command signal.

The blower movement of the fan is a reciprocating movement, and the sensor 37 also detects inversion, and the control unit sends a signal retroactive from the inversion point to an output device based on the signal. Because it is possible, the afterimage of the reciprocating movement of the fan on the “outbound path” can be traced back to the “return path”. This mechanism is the same as the circuit in which the characters are printed in the normal order after printing even in the “return path” of the print head of the dot type printing machine, and the printing order is retroactive.

In the figure, the positions of the LED element rows along the elapse of the fan motion shown at 27 in FIG. 2 are indicated by 30 in the figure, that is, 1 to 16 in the vertical direction are the numbers of the individual LED elements. In the figure, 31 directions, that is, 1 to 16 in the horizontal direction indicate the horizontal position of the LED element row along with the elapsed time. When the former is regarded as the y-axis and the latter as the x-axis, each position can be represented by coordinates (x, y). For example, the LED element 28 is (6, 15), and the LED element position 29 is (16, 15). , 3).

In FIG. 2, 19, each LED element 26 having a short side in the vertical direction of 2.5 mm is considered as one dot, and 16 of these are arranged on a straight line such that the short sides are arranged. As shown in 2-19, a vertical straight line of 40 mm is formed. If this is all lit, it looks like a vertical straight line of 40 mm light, and if only both ends are lit, it looks like two light points about 40 mm apart. The control system of the digital controller shown in FIG. 3 is based on the control unit 35, starts operation by detecting the motion of the sensor 37, extracts the lighting state of the LED element from the memory based on the built-in clock signal, and assembles the signal. And a command to the output device 38, a voltage application to each LED element of the LED element array 19, a retrospective operation by inversion detection by the sensor 37, and the like.

When an ordinary fan with a total length of about 35 cm is grasped by hand and fanned, it is usually about 3 reciprocations / second, and if the fan amplitude of the LED element row portion in FIG. The moving speed of the row is 600 mm / sec, which is a considerably slow moving speed. Speaking of human visual afterimages, it can be visually recognized as characters, symbols, and figures as visual afterimages even once on the outward path.

In FIG. 2, 27 is an example in which the pitch of each LED element in the vertical direction is 2.5 mm, and the position pitch in the horizontal direction is 5 mm at the bottom. If the flash time for lighting is controlled so as to be approximately 1/300 (0.0033) to 1/500 (0.002) seconds, each lighting LED element will light up once while moving. It looks like a dashed line or a line in the horizontal direction, and at the reversal point of reciprocation, it stops for a moment, so it looks like a dot (dot).

Each of the LED elements in the LED element row of the element row 19 in FIG. 2 at the horizontal position 1 (this is referred to as a horizontal position 1) based on the elapsed movement time is (1, 1) to (1, 16). Not all lights. The elapsed time from the horizontal position 1 to the horizontal position 2 is 0.0083 seconds, and at the horizontal position 2, (2, 1), (2, 2), (2, 15), and (2, 16) are lit. Furthermore, 0. At the horizontal position 3 after 0083 seconds, all of (3, 1) to (3, 16) are turned on. Further, at the horizontal position 4 after 0.0083 seconds, all of (4,1) to (4,16) are turned on. Further, at the horizontal position 5 after 0.0083 seconds, (5, 1), (5, 2), (5, 15), and (5, 16) are turned on. At the horizontal position 6, (6, 1) to (6, 16) are not all lit.

Hereinafter, lighting control is similarly performed for the horizontal position 7 and subsequent positions as indicated by 27 in FIG. 2, and the time required from the horizontal position 1 to the horizontal position 16 is approximately 0.13 seconds. As Baal any strong light human visual afterimage time is long, because the afterimage time when the luminance 40 cd / ^{m 2} about LED element is considered roughly 0.4 to 0.6 seconds to, the LED light emission As a result, the image looks like "IT" as shown at 27 in FIG.

Note that 27 in FIG. 2 shows the relationship between the horizontal position of the LED element array 19 and the lighting of the LED elements (black circles). Since it looks continuous and becomes a chain line or a line, it can be more clearly recognized as “IT”. Although not shown in 27 in FIG. 2, the elapsed time up to about the horizontal position 64 is approximately 0.5 seconds, and the afterimage of the lighting LED element near the horizontal position 2 does not disappear. About eight half-width characters can be displayed in afterimages.

In FIG. 2 at 27, when the vehicle further reverses on the outward path to the horizontal position 16 on the outward path and returns to the horizontal path at this lateral position, characters, symbols, and figures that appear on the outward path due to the visual afterimage phenomenon are not reflected on the backward path. It is possible to retroactively appear at substantially the same position as the forward path. That is, in the lighting state of 27 (black circle) in FIG. 2, the horizontal position of the outward path is 〜, 12, 13, 14, 15, 16; 12. Control by a controller to appear as

As described above, since the lighting position is substantially the same as the location of the forward path, that is, the same lighting state at substantially the same declination position of the arc, the appearance time of the character of “IT” is doubled, and only the outward path is used. Character recognition becomes clearer than in the case of. If this is set to two round trips, the appearance time will be twice as long as this, and it can be recognized more clearly.

Assuming that two characters of “TE” are made to appear after two characters of “IT” by the 27 lighting LED elements in FIG. 2, for example, first, two round trips of “IT” and “TE” In the control state of the controller, which is two reciprocations, the emergence time of “IT” is about 0.5 seconds, and then the emergence time of “TE” is about 0.5 seconds. Recognizable. In this way, characters, symbols, and figures of about eight half-width characters can be revealed one after another.

The mechanism of the afterimage appearance is the same as that of a dot-type printing machine which is just one of printing machines such as a computer. In this case, a dot pin array corresponding to the LED element array 19 in FIG. The print head that has the direction, in the formation of characters, symbols and figures, is the position accompanying the time in the horizontal direction, and only the necessary dot pins at that position strike the paper surface via the ink ribbon, and the dots are printed, This is conceptually the same as the mechanism in which letters, symbols and figures are printed on paper. Corresponding to the case of the present invention, the dot pin array of the print head corresponds to the LED element array 19 in FIG. 2, and the position of the print head over time corresponds to the position 27 of the LED element array over time. The stamped characters, symbols, and figures appearing in the above correspond to the characters, symbols, and figures formed by the lighting LED elements that are revealed in the afterimage of human vision.

In the case of a dot printing machine, the printing becomes more precise as the number of dots increases. For example, it is difficult to arrange 24 pins in the vertical direction of the print head in the most general printing machine with 24 dots on each side. When arranged in a staggered manner, one side in the vertical direction is similar to 24 rows. Similarly, in the case of the present invention, the LED element rows may be not one row as shown in FIG. 2 but two rows or plural rows, and these plural rows may be staggered arrangement.

A digital circuit is a circuit having a mechanism for controlling digital signals in the order of pulse signals of a specific frequency. A digital signal is a signal having a meaning only when it is greater than or less than a predetermined value (threshold value), and a general digital electronic circuit is a binary digital circuit. There is one threshold value. For example, this is set to 2 V, the high potential is set to 3 to 5 V, and the low potential is set to 0 to 1 V.

On the other hand, in terms of the elapsed time, it is usual to use a clock signal indicating at which moment the value of the signal is of interest. In general, a synchronous theory method is used to determine whether the value of the signal at or below the threshold value.

The digital control used in the present invention is controlled in the order of clock signals of a specific frequency in the controller. Clock signals generally use oscillators that use the piezoelectric effect (piezo effect) of crystals, and include quartz, Rochelle salt, barium titanate, and EDT. In the case of quartz, about 1 kHz to 100 MHz. The oscillation frequency up to is obtained. In the case of the present invention, it is only necessary to obtain a clock signal of about 4 kHz to 10 kHz from the viewpoint of the purpose and cost of the present invention. Therefore, an arbitrary clock signal device is used on the premise of a higher frequency in consideration of cost and the like.

In the case of the present invention, since the brightness of the LED element at the time of lighting is about 10 to 100 cd / m ² from the viewpoint of the purpose of the present invention and cost, the afterimage time is considered from the flash time. Since it is considered to be about 0.4 to 0.6 seconds, in the case of a dot configuration of an LED element row composed of 16 LED elements, as described above, the horizontal direction is 8 dots of 8 half-width characters. If it is assumed that a character is exposed under this condition, since 16 × 8 × 8 = 1024, the minimum number of necessary memories (ROM; read access memory or RAM; random access memory) is as follows. A combination of one 8-bit byte and one 2-bit byte may be used.

Next, the relationship between the digital electronic circuit built in the handle portion of the fan and the like and the appearance of the after-image in the air will be described. FIG. 3 shows an example of a block diagram of the digital electronic circuit section of the present invention. The thick lines connecting the blocks and parts symbols indicate the flow of data and control, and the thin lines indicate the power supply paths. In FIG. 3, 35 is a digital control unit having a built-in clock signal, 36 is a memory, 37 is a sensor that senses the movement of the fan and detects the reversal of the movement direction, and a transducer that converts this to an electric signal. It is a sensor consisting of

Reference numeral 19 in FIG. 3 denotes an LED element array, 38 denotes an output device, 39 denotes an electric wire for applying a voltage for lighting the LED, and a circuit is formed by a separate electric wire for each LED element. To indicate that The output device 38 turns ON / OFF a predetermined voltage application to each LED element of the LED element row 19 based on a voltage ON / OFF command signal from the control unit 35 assembled by a signal taken out of the memory 36 in the order of the clock signal. I do. Reference numeral 42 denotes an input device. When a ROM is used for the memory 36, a character, a symbol, or a graphic for clarifying a residual image is input at the time of manufacture. When a RAM is used, an optional device such as a separately-built accessory is used. Is a device for inputting characters, symbols, or figures that reveal afterimages. The memory of the present invention may be any of these, and in the latter case, an input device is required.

Even when the switch 41 is turned on, the electric signal from the sensor 37 to the control unit is “stopped” in the stationary state. If the fan motion is started by hand, the sensor 37 detects the movement of the fan, and the signal to the controller is "operation". The control unit 35 fetches the signal from the memory 36 in accordance with the pulse order of the clock signal, and the control unit 35 assembles a signal for displaying an afterimage of a character, a symbol or a figure based on the signal, sends a command signal to an output device, and Accordingly, the output device turns ON / OFF voltage application to each LED element in the LED element row.

Since the blower movement of the fan is a reciprocating movement, the sensor 37 also detects the reversal, and the signal can cause the control unit to send a signal retroactive from the reversal point to the output device. . In this case, since the afterimage of the reciprocating motion of the fan will be traced back on the “return”, the remnant image of the fan can be made to appear at almost the same position regardless of the reciprocating motion of the fan. It becomes easy to read because the manifestation of the image is long. This is a circuit similar to the mechanism that makes the printing order to go back in the `` return path '' so that characters etc. are printed in the normal order after printing on the `` return path '' of the print head of the dot type printing machine. is there. Similarly, the number of round trips in which the same character, symbol or figure repeatedly appears can be controlled by the control unit.

Since the clock pulse frequency is constant, 27 in FIG. 3 indicates that the distance between the position numbers when the fan amplitude of the fan is 10 cm and the frequency is 3 reciprocations / sec, that is, when the fan speed is 600 mm / sec. It is about 5 mm, but if the speed is 1.5 times with the same amplitude, that is, 4.5 reciprocations / second and the speed is 900 mm / second, the characters with the afterimage appear 1.5 times as wide as Emerging characters, symbols and figures are horizontally long. Therefore, in the case of the present invention, there is a feature that characters and the like become horizontally long as the fan is quickly fanned, which is also one of the functions of the present invention.

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

(1) Fans and fans are tools for the function of sending the wind, but there has been little proposal for adding another function, and the wind is passive such as accompanied by the odor of perfume or the like. Although there were only a few examples of addition, we could provide a device that actively utilizes the reciprocating motion of the fan and adds an illuminated function that can be visually stimulated. (2) The LED device is used as a mechanism to add a sense of visual sensibilities by utilizing the blowing motion of a handheld fan and a fan for the purpose of seeking coolness, and the LED device is turned on by a simple controller. With control and the visual afterimage phenomenon, we devised a device that makes characters, symbols, and graphics appear as if they were illuminated in the air. (3) The faster the fan is played, the more the characters, symbols, and figures revealed by the visual afterimage phenomenon become horizontally long, which has the further effect of adding fun. (4) If the fan or fan of the present invention is used, such as when driving in a dark place such as at night, the LED can be used as a traffic safety tool because the LED emits light. (5) It is useful to add another function using the mechanism that reveals the original function from the viewpoint of efficient use of energy, etc. In addition to the original fan function of the fan, In other words, in this case, an effective electric decoration function could be added by adding a small amount of electric energy with almost no increase in human load. As described above, the present invention can be applied to a pendulum of a clock, a pendulum of a metronome, a pendulum toy, and the like, in addition to a fan and a fan. Also, the present invention can be applied to a rotating body that does not use a synchronous motor, for example, a rotating body of a bicycle or a windmill that slowly rotates about 1 to 3 rotations per second.
