Description

Technical Field

[0001] The present invention relates to a wind direction display device, a wind direction display system, and its constituent members that facilitate visual confirmation of the wind direction in flags and streamers that react to the wind direction when it is difficult to visually confirm the wind direction.

Background Art

[0002] Hitherto, as means for visually confirming the wind direction, means based on the movement of lightweight sheet-like objects that flutter in the wind, such as a tubular type of "streamer" that flutters in the wind and a "pin flag" that indicates the golf cup position and the wind direction, means based on the direction of a wind direction and speed meter with a propeller (windmill), means based on the direction of a weather vane (weather cock, etc.) or arrow feathers, etc. have been used.

[0003] Patent Document 1 describes a technique for displaying data obtained from a wind direction and speed meter on a screen as means for displaying more detailed wind direction and wind speed, but these require a power source and lack simplicity.

[0004] Patent Document 2 describes a technique for filling a cylindrical hollow body with a gas that cancels out the weight of the hollow body components to enable more detailed confirmation of the wind direction, but there is no description of means for discriminating which wind direction it is in the case of a following wind or a headwind.

[0005] Regarding the discrimination of the wind direction related to a golf course, there is Patent Document 3. According to this document, it is stated that a wind direction meter using an arrow or the like is provided near the fairway of a golf course, but since it does not directly indicate the wind direction near the hole on the green, its usefulness is low.

[0007] The problem that this invention aims to solve is to provide a wind direction display device that does not require artificial power such as a power supply and allows for easy visual confirmation of wind direction, and in particular to provide a wind direction display device that allows for easy visual confirmation when the wind direction is in a straight line with the observer, such as in the case of a headwind or tailwind. [Means for solving the problem]

[0008] A wind direction display device according to a first aspect of the present invention includes a wind direction reaction unit that reacts according to the wind direction, a rotating coupling body that rotatably connects the wind direction reaction unit to a support column that stands upright in a substantially vertical direction, and a wind direction identification unit attached to a predetermined location on the rotating coupling body.

[0009] In this way, without requiring any artificial power, the movement of the wind direction sensing unit is transmitted to the rotating coupling, and the wind direction identification unit attached to the rotating coupling can display the correct wind direction in a way that is easily identifiable to the observer.

[0010] In this embodiment, the support column is not included in the defining features of the invention. The support column may be a new one or an existing one, and the defining features of the invention are only the rotating coupling body with a wind direction identification unit attached to the support column, and the wind direction reacting unit fixed to the rotating coupling body.

[0011] The support columns extend upward in a nearly vertical direction from the ground surface, water surface, automobile, or other moving object, and may be designed to be inserted into support structures such as holes on a golf course. The material can be any material that ensures sufficient strength, such as metal, plastic, or wood.

[0012] Furthermore, "approximately vertical" includes cases where the orientation deviates slightly (by about 5 degrees from the vertical) due to installation errors, wind effects, or when the object is held in a loose support, such as a flagpole on a golf course green.

[0013] The wind direction reacts according to the wind direction when it blows, and can be anything such as a flag, windsock, banner, or windmill.

[0014] The rotating connector is the part that connects the support column and the wind direction responding unit. The support column is held rotatably using bearings or the like, and the wind direction responding unit is attached in a way that allows the wind direction to be transmitted directly.

[0015] Here, the wind direction identification unit attached to the rotating coupling body includes, but is not limited to, providing the rotating coupling body itself with a wind direction identification function, and attaching a separate wind direction identification unit to the rotating coupling body; any function that can identify wind direction is acceptable.

[0016] Next, a second aspect of the present invention is a wind direction display device according to the first aspect, characterized in that a predetermined location of the rotating coupling is on the opposite side of the rotating coupling from the mounting location of the wind direction reacting unit.

[0017] Here, the opposite side of the mounting location of the wind direction responder refers to, for example, if the wind direction identification unit is provided on the cylindrical rotating coupling itself, all or part of the outer side of the semi-cylindrical portion opposite the circumferential position where the wind direction responder is mounted.

[0018] By adding color or other distinguishable measures to this section, when the wind is blowing towards the support pole (tailwind), the colored or distinguishable section becomes visible throughout the entire area, making it easy to identify that there is a tailwind.

[0019] On the other hand, in the case of a headwind blowing from the support pole towards the observer, the parts that have been marked with identifiable colors or other features become completely invisible, allowing one to determine that it is a headwind.

[0020] Also, in the case of a crosswind from the side, for example, in the case of a crosswind from the right, a predetermined part of the rotating coupling can be easily identified because it can be visually observed only on the right side by the viewer.

[0021] In the case of a crosswind from the left, conversely, a predetermined part of the rotating coupling can be easily identified because it can be visually observed only on the left side by the viewer.

[0022] In the case of a crosswind that is not from directly the side, depending on the direction, the position and size of a predetermined part of the rotating coupling seen by the viewer are different, so the viewer can easily identify the direction.

[0023] Note that the predetermined part of the rotating coupling may be on the same side as the attachment part of the wind direction reaction part for the rotating coupling. Even in that case, although the identification of the wind direction is reversed, the same effect can be exhibited.

[0024] Next, a third aspect according to the present invention is a wind direction display device according to the first aspect of the present invention, characterized in that a wind direction identification part attached to the rotating coupling is provided on the rotating coupling itself.

[0025] That is, a wind direction identification function is provided on the rotating coupling itself. As a function for identifying the wind direction, it is preferable to attach a specific color, pattern, etc. to a predetermined part of the rotating coupling, but other means such as a shape, marking, or something that emits light or sound that can identify the wind direction may also be used.

[0026] By doing so, a device for displaying the wind direction can be realized with a simple configuration.

[0027] Next, a fourth aspect according to the present invention is a wind direction display device according to the first aspect of the present invention, characterized in that a wind direction identification part attached to the rotating coupling is a member having an identification function fixed to the rotating coupling.

[0028] In other words, for example, it is a separate component fixed to the rotating joint by screws or adhesive, preferably having a roughly semi-cylindrical shape, capable of performing the same rotational motion as the rotating joint, and possessing a function that allows for the identification of wind direction, such as color and shape, as described above.

[0029] This approach offers several advantages, including increased flexibility in dimensions and materials by using different components, allowing for improved identification capabilities, and the ability to use existing rotating joints with minimal modification.

[0030] Next, a fifth aspect of the present invention is a wind direction display device according to the fourth aspect, further characterized in that it has a blocking plate provided on the opposite side of the wind direction identification unit to the rotating coupling body, and together with the wind direction identification unit, to cover the rotating coupling body.

[0031] In this configuration, it is preferable that the wind direction identification section is semi-cylindrical, the blocking plate is also semi-cylindrical, and that these completely cover the rotating joint so that the cross-section perpendicular to the extension direction of the support column is approximately circular.

[0032] This approach has several advantages, including reduced resistance to wind and the ability to follow the wind direction more smoothly.

[0033] Next, a sixth aspect of the wind direction indicator system according to the present invention is characterized by comprising a support column that stands upright in a substantially vertical direction, a wind direction reaction unit that reacts according to the wind direction, a rotating coupling body that rotatably connects the wind direction reaction unit to the support column, and a wind direction identification unit attached to the rotating coupling body.

[0034] This embodiment adds a support column to the wind direction display device in the first embodiment, creating a system that can fully perform the function of displaying wind direction.

[0035] According to this, for example, it can be used to confirm wind direction to ensure safety during the takeoff and landing of visually controlled aircraft such as helicopters.

[0036] Next, a seventh aspect of the present invention is a wind direction indicator system according to the sixth aspect, wherein the end of the wind direction reacting part has a cylindrical part formed so as to be wrapped around the support column, and the cylindrical part is rotatably attached to the support column and functions as the rotating coupling.

[0037] This approach eliminates the need to prepare the rotating joint as a separate component, resulting in a simpler structure.

[0038] Next, an eighth aspect of the present invention is a wind direction indicator system according to the sixth or seventh aspect, characterized in that the support column is a flagpole on a golf course and the wind direction reacting unit is a pin flag.

[0039] Here, a flagstick is used by inserting it into the hole support on a golf course's putting green, but it can also be placed in other locations besides the green as a guide for shots.

[0040] Furthermore, a pin flag is a flag bearing the hall number or other information, held on a flagpole via a rotating connector, and fluttering depending on the wind direction.

[0041] This method is extremely effective when you want to accurately determine the wind direction on the green at a golf course, especially when you want to know whether it's a headwind (against your head) or a tailwind (behind your head).

[0042] . Next, a wind direction indicator system according to a ninth aspect of the present invention is characterized by comprising a support column that stands upright in a substantially vertical direction, a wind direction reacting unit that reacts according to the wind direction, a cylindrical portion to which the end of the wind direction reacting unit is wrapped around and fixed to the support column, a wind direction identification unit attached to the cylindrical portion, and a support column rotation holding unit that rotatably holds the support column.

[0043] That is, for example, the end of a wind direction-sensitive part, such as a cloth flag, is wrapped around a support pole to form a cylindrical shape, which is then fixed to the pole.

[0044] Furthermore, on the side of the cylindrical section opposite to the side that responds to wind direction, a wind direction identification section is provided, similar to previous designs, using coloring or other means.

[0045] On the other hand, the support column is not fixed to the ground surface or the like, and has a rotating support column holder that holds the column in a rotatable manner.

[0046] In this configuration, although it does not have a rotating coupling that rotatably holds the wind direction reacting unit as in previous embodiments, it instead has a rotating support unit, and can achieve the same effects as in previous embodiments.

[0047] Next, a tenth aspect of the present invention is a wind direction indicator system according to the ninth aspect, characterized in that the support column is a flagpole in a golf course, and the wind direction reacting unit is a pin flag.

[0048] Here, the rotating support column is designed to hold the flagpole, which is a support column, in a hole on a golf course green, in a rotatable support device (housing) installed inside the hole.

[0049] This simple design makes it extremely effective for accurately determining wind direction on the greens at a golf course.

[0050] Next, the 11th aspect of the present invention is a rotating coupling for a wind direction display device, which rotatably connects a wind direction reacting unit that reacts according to the wind direction with a support column that stands upright in a substantially vertical direction, and is further characterized by being equipped with a wind direction identification unit.

[0051] This embodiment defines the invention solely as a rotating connector with a wind direction identification unit. By fixing a wind direction reaction unit to this unit, or by rotatably connecting it to a support column, it performs the function of indicating wind direction. This part is an important element of the invention. [Effects of the Invention]

[0052] According to the present invention, it has become possible for observers to easily identify the wind direction. This is particularly effective in the case of tailwinds and headwinds. [Brief explanation of the drawing]

[0054] A first embodiment of the present invention will be described below with reference to the drawings. In the following description, only the extent necessary for explaining the objectives of the present invention will be shown, and any parts omitted from the explanation will be considered known technology.

[0055] <Structure> Figure 1 is a perspective view of a wind direction indicator system according to a first embodiment of the present invention, and Figure 2 is a partial perspective view of the same wind direction indicator system.

[0056] The wind direction display system 100 includes a flag 10 that flutters according to the wind direction, which is an example of a wind direction response unit; a rotating connector 20 to which the flag 10 is fixedly attached; a wind direction identification unit 30 attached to the rotating connector 20 (these parts constitute the wind direction display device); and a support column 40 that stands approximately vertically from the ground surface or the like, which rotatably connects the rotating connector 20.

[0057] As shown in Figure 2, the flag 10 is attached by tying three attachment strings 11 extending from the flag 10 to each of the rings 21 embedded and fixed in each of the three rotating connectors 20.

[0058] In other words, the rotational motion of the flag 10 due to the wind direction is transmitted to the rotating connector 20 via the attachment string 11 and ring 21, causing the rotating connector 20 to rotate.

[0059] The rotating coupling 20 has a cylindrical shape, and its inner side is rotatably fitted onto the support column 40. The fitting portion is preferably made up of a bearing or a sliding bearing.

[0060] Furthermore, means to prevent the rotating coupling 20 from moving downwards may include providing a step in the support column 40 or fixing a separate cylindrical member to the support column 40 in contact with the lower part of the rotating coupling 20.

[0061] The wind direction identification unit 30 is painted red on the cylindrical outer portion of the rotating coupling body 20, extending 90 degrees on each side in the circumferential direction from the point opposite the ring 21 to which the flag 10 is attached. Note that this angle can be larger (for example, 120 degrees on each side), or Smaller angles (60 degrees each) are also acceptable; there are no restrictions on the angle.

[0062] The support column 40 can be any ordinary support column, but as an example, we can imagine a pin flag inserted into the hole support section of a golf course.

[0063] <Operation> This document explains how to operate (use) such a wind direction indicator system. If a person observing wants to accurately determine the wind direction, for example, if a person observing (a golfer) wants to know the exact wind direction on the green where they are about to take a shot, they can simply look at the wind direction display system of this invention.

[0064] In other words, when the entire red portion of the wind direction identification section 30 provided (coated) on the rotating coupling 20 is visible, the wind direction on the green can be determined to be a tailwind towards the support column 40 from the perspective of the observer.

[0065] The color to be applied is not limited to red; any conspicuous color, such as a contrasting color to the flag or pole, is preferable, and light-diffusing and reflective materials such as fluorescent or phosphorescent materials are also desirable. In addition to paint, colored stickers or other materials may also be applied.

[0066] On the other hand, if the red portion of the wind direction identification unit 30 is not visible at all, the wind direction on the green can be determined to be a headwind from the direction of the support column 40 as seen by the observer.

[0067] Furthermore, if the wind direction identification unit 30 is partially visible, its position and the amount visible will allow us to determine whether it is a crosswind, or a crosswind with a tailwind or headwind.

[0068] <Variation> Next, a modified example of the first embodiment of the present invention will be described. Figure 3 is a perspective view of a modified example of the wind direction display system of the first embodiment of the present invention, and Figure 4 is a partial perspective view of the same modified example of the wind direction display system.

[0069] In this modified version, a windsock 15 is used as the wind direction responder instead of the flag 10 described above. The windsock 15 is fixed to the rotating connector 20 via connectors 16 provided in two locations.

[0070] The connector 16 is preferably a metal plate extending from the frame 151 at the mouth of the windsock 15, but is not limited to this, and can be any connector that can fix the windsock 15 to the rotating connector 20.

[0071] The rotating coupling 20, the wind direction identification unit 30 provided on the rotating coupling 20, and the support column 40 are the same as described above, so their description will be omitted.

[0072] However, in addition to its use on golf courses, it can also be used to check wind direction to ensure the safety of visual aircraft such as helicopters during takeoff and landing.

[0073] Figure 5 is a perspective view of another modified example of the wind direction indicator system according to the first embodiment of the present invention, in which the windsock 15 may be connected to the rotating coupling 20 by three attachment strings 17 and one connecting string 18 bundling them together. In this case as well, if the rotating coupling 20 is provided with a wind direction identification unit 30, similar functionality can be achieved.

[0074] Next, a second embodiment of the present invention will be described with reference to the drawings. In the following, only the extent necessary for explaining the objectives of the present invention will be indicated, and parts that are omitted from the explanation will be considered known technology. Also, the same reference numerals will be used for the same parts as in the first embodiment, and their explanation may be omitted.

[0075] <Structure> Figure 6 is a perspective view of the wind direction indicator system of the second embodiment of the present invention before assembly, Figure 7 is a perspective view of the wind direction indicator system after assembly, and Figure 8 is a horizontal cross-sectional view of the wind direction indicator system.

[0076] The wind direction indicator system 100 includes a flag 10 that flutters according to the wind direction, which is an example of a wind direction response unit; three rotating connectors 20 to which the flag 10 is fixedly attached; a wind direction identification unit 35 fixed to (attached to) the rotating connectors 20; and a support column 40 that stands approximately vertically from the ground surface or the like, which rotatably connects the rotating connectors 20.

[0077] The method for attaching the flag 10 to the rotating connector 20 is the same as in the first embodiment, so a description will be omitted.

[0078] The rotating coupling 20, like in the first embodiment, has a cylindrical shape, and its inner side is rotatably fitted onto the support column 40. The fitting portion is preferably composed of a bearing or a sliding bearing.

[0079] The wind direction identification unit 35 is a plate material with a semicircular cross-section that covers a range of 90 degrees on both sides in the circumferential direction from the point on the opposite side in the circumferential direction from the cylindrical outer portion of the rotating coupling body 20 where the flag 10 is attached, and extends perpendicular to the cross-section to cover three rotating coupling bodies 20.

[0080] The wind direction identification unit 35 is connected to three rotating connectors 20 by three screws 351. The connected state is shown in Figure 7.

[0081] The wind direction identification section 35 is preferably painted red, but as in the first embodiment, it may be other colors or an adhesive material.

[0082] The support column 40 can be any ordinary support column, but as an example, we can imagine a pin flag inserted into the hole support section of a golf course.

[0083] <Operation> This document explains how to operate (use) such a wind direction indicator system. In terms of operation, it is the same as in the first embodiment. If a user wants to accurately determine the wind direction, for example, if a user (golf player) wants to know the exact wind direction on the green where they are about to take a shot, they can simply look at the wind direction display system of the present invention.

[0084] Furthermore, since the wind direction identification unit 35 can be made large enough to cover the three rotating couplings 20, it may be possible to more easily identify the wind direction.

[0085] <Structure of the variation> Figure 9 is a perspective view of a modified wind direction indicator system according to the second embodiment of the present invention before assembly, and Figure 10 is a perspective view of the same modified wind direction indicator system after assembly.

[0086] In this modified version, a windsock 15 is used as the wind direction responder instead of the flag 10 described earlier. The windsock 15 is fixed to two rotating connectors 20.

[0087] The rotating connector 20, the wind direction identification unit 35 fixed to the rotating connector 20, and the support column 40 are the same as described above, so their description will be omitted.

[0088] The wind direction identification unit 35 is connected to the two rotating connectors 20 by two screws 351, as described above. The connected state is shown in Figure 10.

[0089] <Application of Variant Forms> The operation of this modified example is the same as described above, so we will omit the explanation.

[0090] Next, a third embodiment of the present invention will be described with reference to the drawings. In the following, only the extent necessary for explaining the objectives of the present invention will be indicated, and parts that are omitted from the explanation will be considered known technology. In addition, the same reference numerals will be used for parts that are the same as those in the first or second embodiment, and their explanation may be omitted.

[0091] <Structure> Figure 11 is a perspective view of the wind direction indicator system of the third embodiment of the present invention before assembly, Figure 12 is a perspective view of the same wind direction indicator system after assembly, and Figure 13 is a horizontal cross-sectional view of the same wind direction indicator system.

[0092] The wind direction indicator system 100 includes a flag 10 that flutters according to the wind direction, which is an example of a wind direction response unit; three rotating connectors 20 to which the flag 10 is fixedly attached; a wind direction identification unit 35 fixed to (attached to) the rotating connectors 20; a blocking plate 36 provided on the opposite side of the wind direction identification unit 35 and the rotating connectors 20; and a support column 40 that rotatably connects the rotating connectors 20 and stands approximately vertically from the ground surface or the like.

[0093] The method for attaching the flag 10 to the rotating connector 20 is the same as in the first embodiment, so a description will be omitted.

[0094] The rotating coupling 20, like in the first embodiment, has a cylindrical shape, and its inner side is rotatably fitted onto the support column 40. The fitting portion is preferably composed of a bearing or a sliding bearing.

[0095] The wind direction identification unit 35, similar to the second embodiment, is a plate material with a semicircular cross-section that covers a range of 90 degrees on both sides in the circumferential direction from the point on the opposite side in the circumferential direction from the cylindrical outer portion of the rotating coupling 20 where the flag 10 is attached, and extends perpendicular to the cross-section to cover three rotating couplings 20.

[0096] Furthermore, a blocking plate 36 is provided. This is provided on the side of the rotating coupling 20 opposite to the wind direction identification unit 35, and is a plate material with a semicircular cross-section formed to cover a range of 90 degrees on both sides in the circumferential direction, and extending perpendicular to the cross-section to cover the three rotating couplings 20.

[0097] In other words, since a semi-cylindrical plate with the same dimensions as the wind direction identification unit 35 is attached to the opposite side of the wind direction identification unit 35, the rotating coupling body 20 is covered by the wind direction identification unit 35 and the blocking plate 36, and in the cross section perpendicular to the support column 40, the outermost circumference becomes circular.

[0098] This approach reduces wind resistance, allowing the ball to follow the wind direction more smoothly, and also completely eliminates any issues with the golf equipment rules that state "the cross-section of the flagstick must be circular."

[0099] <Operation> The operation is the same as in the second embodiment, so the explanation will be omitted.

[0100] Next, a fourth embodiment of the present invention will be described with reference to the drawings. In the following, only the extent necessary for explaining the objectives of the present invention will be indicated, and parts that are omitted from the explanation will be considered known technology. Also, the same reference numerals will be used for parts that are the same as those in the first to third embodiments, and their explanation may be omitted.

[0101] <Structure> Figure 14 is an overall perspective view of the wind direction indicator system according to the fourth embodiment of the present invention, and Figure 15 is a detailed perspective view of the same wind direction indicator system.

[0102] The wind direction indicator system 100 includes a support column 40 that stands approximately vertically from the ground surface, a flag 10 which is an example of a wind direction response unit and flutters according to the wind direction, and a cylindrical part 19 formed so that the end of the flag 10 opposite to the fluttering side is wrapped around the support column 40.

[0103] Here, the cylindrical portion 19 is provided with a holding portion (not shown) that prevents it from moving vertically downward relative to the support column 40, and is rotatably held relative to the support column 40. In other words, this cylindrical portion 19 performs the same function as the rotating coupling portion 20 in previous embodiments.

[0104] Furthermore, the semicircular portion of the cross-section of the cylindrical part 19 on the side opposite to the side of the flag body 10 that responds to the wind direction is colored in a specific color, and this portion may be considered as the wind direction identification part 35.

[0105] <Operation> The operation is the same as in the second embodiment, so the explanation will be omitted.

[0106] In this way, the wind direction display function can be realized using existing flags 10 and poles 40, making practical implementation easy.

[0107] <Variation> One modification of the fourth embodiment is that the cylindrical portion 19, which may be provided at the end of the flag 10 shown in Figures 14 and 15, is fixed to the support column 40 in a way that prevents rotation.

[0108] Furthermore, the semicircular portion of the cross-section of the cylindrical part 19, on the side opposite to the side of the flag body 10 that responds to the wind direction, is colored in a specific color, and this portion may be considered as the wind direction identification section 35.

[0109] On the other hand, the support column 40 is not fixed to the ground surface or the like, and has a support column rotation holding part (not shown) that holds the support column 40 in a rotatable manner.

[0110] For example, in a golf course green, the flagpole, which is a support column 40, is held in a rotatable holder (housing) installed inside the hole.

[0111] In this configuration, although it does not have a rotating holding part that rotatably holds the flag 10 on the support column 40 as in previous embodiments, it instead has a rotating holding part for the support column, and can achieve the same effects as in previous embodiments.

[0112] <Operation> The operation is the same as in the second example, so the explanation will be omitted. [Industrial applicability]

[0113] The wind direction display device of the present invention meets the need to visually recognize the wind direction at the location of a distant object, and since such a need exists widely in industry, the present invention has great industrial applicability. [Explanation of symbols]
