Description

  The present invention relates to a flag display device for displaying flag flags. More specifically, the present invention relates to a flag flag display device that has been devised so that the flag flag displayed and the lifting rope for lifting the flag flag do not wrap around the pole even during strong winds.

  The flag that is displayed at the time of advertising at a store or when a festival is held at a shrine passes a plurality of circular strings attached to its inner edge through a vertical pole standing on the ground and its upper edge. It was displayed by passing a plurality of other annular cords attached to the top of the vertical pole through a horizontal arm extending in the horizontal direction from the vicinity of the upper end of the vertical pole. In the old days, wooden poles and horizontal arms were used, but metal parts with excellent durability and aesthetics have been adopted since then. Currently, various devices have been applied to the flag flag display device for displaying the flag flag, such as enabling the flag flag to be lifted and lowered, and preventing the flag flag from being wrapped around the pole. ing.

  For example, in Patent Document 1, the upper part of a vertical pole has a structure that can rotate horizontally, and a horizontal arm is attached to the horizontally rotatable part of the vertical pole. Have been proposed). In the flag hoisting device of Patent Document 1, one end of the lifting rope led along the vertical pole and the horizontal arm is fixed to the upper edge of the flag flag, and the other end is provided near the base of the vertical pole. It can be wound up by a lifting rope winding means.

  In the flag raising device of Patent Document 1, the flag is raised by winding the lifting rope around the lifting rope winding means, and on the contrary, the flag can be lowered by unwinding the lifting rope from the lifting rope winding means. It is like that. In addition, since the flag is able to rotate freely according to the wind direction, it is possible not only to reduce the wind pressure received by the flag but also to prevent the flag from wrapping around the vertical pole It has become. As described above, the eaves flag display device of Patent Document 1 has various advantages compared with the previous eaves flag display device. However, when the upper part of the vertical pole rotates horizontally, Due to the twisted structure, the lifting rope had the disadvantage of being easily painful.

  In view of such a situation, for example, in Patent Document 2, a connecting member is interposed in the middle of an elevating rope, and a portion above the connecting member and a portion below the connecting member in the elevating rope are provided. There has been proposed an upper rotation type flag banner display device that is relatively horizontally rotatable. Thereby, even if the upper part of the vertical pole rotates horizontally, the lifting rope can be prevented from twisting, so that the lifting rope can be made less painful. In the flag hoisting device of Patent Document 2, the lifting rope is housed inside the vertical pole, so that it is possible to prevent unpleasant metal sounds that can occur when the lifting rope is hit by the wind and hits the vertical pole. However, since the lifting rope is stored inside the vertical pole, there is another drawback that maintenance is complicated such as replacement of the lifting rope.

Japanese Utility Model Publication No. 07-041576 Japanese Patent Application Laid-Open No. 08-086122

  The present invention has been made to solve the above-mentioned problems, and not only can the flag be lifted and lowered, but also prevents the flag flag and the lifting rope from being wound around the vertical pole and the lifting rope to be twisted. The main purpose is to provide an eaves flag display device that can also reduce maintenance work. It is also an object of the present invention to provide a flag raising device capable of automatically raising and lowering the flag according to the strength of the wind.

  The above-described problems include a vertical pole for displaying a flag, an upper rotating member provided on the upper portion of the vertical pole so as to be horizontally rotatable, a horizontal arm provided so as to project horizontally from the upper rotating member, and a vertical pole. A hoisting rope that is guided from the lower side to the upper side along the horizontal arm and that has one end fixed to the upper edge of the flag, a winding operation for winding the other end side of the hoisting rope, and the other end side. An elevating rope winding device for performing an unwinding operation, wherein a lower rotating member that is horizontally rotatable is provided at a lower part of a vertical pole, and the elevating rope is provided on the lower rotating member. The problem is solved by providing a flag raising device in which the winding means is fixed and the upper rotating member and the lower rotating member are interlocked to rotate horizontally with respect to the vertical pole.

  In the flag hoisting device of the present invention, both the horizontal arm passing through one end (upper end) side of the lifting rope and the lifting rope winding means winding the other end (lower end) side of the lifting rope are attached to the vertical pole. On the other hand, it can be rotated horizontally. In addition, a part that rotates horizontally integrally with the upper rotating member, such as a horizontal arm and an upper rotating member (hereinafter sometimes referred to as an “upper rotating group”), a lifting rope winding means, a lower rotating member, and the like. The state in which the part that rotates horizontally integrally with the lower rotating member (hereinafter sometimes referred to as the “lower rotating group”) is connected to each other via an elevating rope, a hanging rope, which will be described later, or the like. It has become. For this reason, when the horizontal arm rotates horizontally, the hoisting rope winding means also follows the rotation. Therefore, not only the direction in which the flag is displayed can be freely changed according to the wind direction, but also the lifting rope can be prevented from being twisted or wound around the vertical pole. Further, since the lifting rope can be arranged outside the vertical pole, maintenance such as replacement of the lifting rope is facilitated.

  The support structure of the lower rotating member with respect to the vertical pole is not particularly limited. However, if the friction of the lower rotating member with respect to the vertical pole becomes too large, the lower rotating member becomes difficult to rotate horizontally, and as a result, there is a risk of inducing problems such as twisting and winding of the lifting rope. For this reason, the lower rotating member is required to be supported by the vertical pole with as little friction as possible. This friction can be caused, for example, by placing a lower rotating member on the upper surface of a thrust bearing fixed to the outer periphery of the vertical pole (when the total weight of the lower rotating group is heavier than the total weight of the flag), The upper surface of the lower rotating member can be hooked on the lower surface of the fixed thrust bearing (when the total weight of the lower rotating group is lighter than the total weight of the flag). However, in this case, since a thrust bearing is required separately, there is a risk of increasing the manufacturing cost of the flag flag lifting device. For this reason, it is preferable to set the total weight of the lower rotation group to be heavier than the total weight of the flag, and to support the lower rotation member in a state suspended from the horizontal arm by the lifting rope. By suspending the lower rotating member in this manner, it becomes possible to support the lower rotating member with a small friction with respect to the vertical pole without using a thrust bearing.

  The upper side rotation group and the lower side rotation group should just be in the state connected only by the raising / lowering rope at least. However, in this case, in order to keep the height of the lower rotating member constant, the weight balance between the lower rotating group and the flag is strictly adjusted, or the lower rotating member is It becomes necessary to support the lower surface. In addition, the angle at which the upper rotation group rotates horizontally and the angle at which the lower rotation group rotates horizontally are less likely to coincide with each other, which may cause twisting of the lifting rope. For this reason, a suspension rope for suspending the lower rotating member from the horizontal arm is provided independently of the lifting rope, and the lower rotating member is suspended from the horizontal arm by the lifting rope and the suspension rope. Support is preferred. This also makes it possible to prevent the lower rotating member from becoming lower than a predetermined height. It is also possible to reduce the difference between the angle at which the upper rotation group rotates horizontally and the angle at which the lower rotation group rotates horizontally.

  The lifting rope winding means may be a manual one, but it is preferable to use an electric one. This makes it possible to automatically raise and lower the flag. It is also possible to remotely raise and lower the flag with a remote controller or the like. In this case, a solar cell or a commercial power source is exemplified as a power supply source required to drive the lifting rope winding means. Among these, it is preferable to use a solar cell. That is, it is preferable to provide a solar cell module that generates power using sunlight and a battery for storing electric power obtained from the solar cell module, and to electrically connect the battery and the lifting rope winding means. As a result, not only can the energy saving of the flag display device be realized, but it is also possible to install the flag flag display device in a place where it is difficult to secure commercial power.

In addition, when an electric one is adopted as the lifting rope winding means, it is possible to automatically raise and lower the flag according to the wind speed or the like. For example, the strong wind detecting means for detecting that the wind speed has exceeded a predetermined value S ₁ and generating a strong wind detection signal in the flag display device, or the wind speed has fallen below the predetermined value S ₂ (S ₂ ≦ S ₁ ). A strong wind release detecting means for detecting the strong wind release detection signal is provided, and when the strong wind detection signal is issued, the feeding operation by the lifting rope winding means is started or the strong wind release detection signal is issued. At this time, it is possible to set so that the winding operation by the lifting rope winding means is started. As a result, it is possible to automatically lift and lower the flag according to the wind speed, and to save time and labor for lifting and lowering the flag. This configuration is suitable for use in large stores that display a large number of flag flags.

  However, in this case, if the hoisting rope winding means continues the winding operation after the upper edge of the flag reaches the top dead center, the lower rotating group starts to rise, so the lower rotating group There is a risk of interference with the flag and excessive load on the lifting rope and lifting rope winding means. On the other hand, if the lifting rope winding means continues to feed after the upper edge of the flag reaches the bottom dead center, the lifting rope is not easily loosened and entangled or twisted. After the wire is completely fed out, the lifting rope is wound around the lifting rope winding means in the opposite direction, which may cause various problems. Therefore, when using an electric one as the lifting rope winding means, a top dead center detecting means for detecting that the upper edge of the flag reaches the top dead center and generating a top dead center detection signal, Alternatively, a bottom dead center detecting means for detecting that the upper edge of the flag flag has reached the bottom dead center and issuing a bottom dead center detection signal is provided, and a top dead center detection signal or a bottom dead center detection signal is issued. At this time, it is preferable to set the winding operation or the feeding operation by the lifting rope winding means to be stopped.

  The top dead center detecting means or the bottom dead center detecting means is particularly limited as long as it can detect that the upper edge of the flag flag has reached the top dead center or the upper edge of the flag flag has reached the bottom dead center. However, it is preferable to have a simple structure that is not easily broken. Specifically, a limit switch equipped with an actuator is used as the top dead center detecting means or the bottom dead center detecting means, and the top dead center is detected when a detected part provided at a predetermined position of the lifting rope comes into contact with the actuator. It is preferable to generate a point detection signal or a bottom dead center detection signal. As a result, the top dead center detection means and the bottom dead center detection means are not easily broken by a simple structure, and the manufacturing cost of the flag display device is reduced, but also the top dead center emitted from the top dead center detection means. It is also possible to stabilize the operation of the flag raising device by increasing the reliability of the detection signal or the bottom dead center detection signal emitted from the bottom dead center detection means.

  As described above, according to the present invention, it is possible not only to lift and lower the flag, but also to prevent the flag flag and the lifting rope from being wound around the vertical pole, to prevent the lifting rope from being twisted, and to reduce the maintenance work. It is possible to provide a flag raising device that can be used. It is also possible to provide a flag raising device that can automatically raise and lower the flag according to the strength of the wind.

1. Overview of the Raft Flag Display Device As shown in FIG. 1, the raft flag display device of the present invention includes a vertical pole 10 for hoisting the flag flag 100, and an upper rotation provided on the vertical pole 10 so as to be horizontally rotatable. A member 20, a horizontal arm 30 extending horizontally from the upper rotating member 20, and a lower pole that is guided from the lower side to the upper side along the vertical pole 10. A lifting rope 40 fixed to the edge, a lifting rope winding means 50 for winding up the other end of the lifting rope 40 and a feeding operation for feeding out the other end; and a lower part of the vertical pole 10 The lower rotary member 60 is provided so as to be horizontally rotatable, and the lifting rope winding means 50 is fixed to the lower rotary member 60. Since the upper rotating member 20 and the lower rotating member 60 are connected by the lifting rope 40, the upper rotating member 20 and the lower rotating member 60 are rotated horizontally with respect to the vertical pole 10 in conjunction with each other.

2. Vertical pole The length and thickness of the vertical pole 10 are appropriately determined according to the size of the flag 100 to be displayed. The length of the vertical pole 10 is usually set to about 1 to 10 m, and the thickness (outer diameter) of the vertical pole is usually set to about 5 to 30 cm. As shown in FIG. 1, the vertical pole 10 has a constant thickness from the lower end to the upper end, but it is also preferable that the vertical pole 10 is formed so as to become thinner toward the tip. . Thereby, the vertical pole 10 can be stabilized against the wind. Further, as shown in FIG. 3, a flange-shaped stopper 11 is provided on the outer peripheral surface of the vertical pole 10 below the lower rotating member 60. For this reason, the lower side rotation member 60 cannot move below the stopper 11.

  The material of the vertical pole 10 is not particularly limited, but usually a metal such as stainless steel or aluminum alloy, or a resin such as reinforced plastic is employed. In the flag display device of this embodiment, the vertical pole 10 is formed of stainless steel having excellent rust prevention and strength. The vertical pole 10 may be solid, but in the flag flag raising device of this embodiment, a hollow one is adopted as shown in FIG. For this reason, the support shaft 21 of the upper rotating member 20 can be inserted into the vertical pole 10 (see FIG. 2), or the electric wires 10c and 10d can be passed through the vertical pole 10 (see FIG. 3). It can be done.

  The method of standing the vertical pole 10 is not particularly limited. For example, a leg (not shown) can be provided at the lower end of the vertical pole 10 so that the vertical pole 10 can stand on the ground. In this case, the vertical pole 10 can be made to stand stably by adopting a heavy weight for the leg or by providing a weight (not shown) at the lower end of the vertical pole 10. In this way, by not fixing the vertical pole 10 to the ground completely, the flag flag display device can be made suitable for temporary installation. Such a temporary-type flag flag display device can be suitably used when a flag flag is temporarily displayed at an event venue or the like and then removed. Further, the lower end of the vertical pole 10 can be completely fixed to the ground. Thereby, it becomes possible to make the vertical pole 10 more stable against the wind. As shown in FIG. 1, the lower end of the vertical pole 10 is completely fixed to the concrete base 14 embedded in the ground in the kite flag display device of this embodiment.

  As shown in FIG. 1, a vertical pole guide ring 101 attached to the inner edge of the flag 100 at a predetermined interval is passed through the vertical pole 10. For this reason, when the flag 100 is displayed, it is possible to keep the inner edge of the flag 100 straight along the vertical pole 10. The material of the vertical pole guide ring 101 is not particularly limited, but if it is too soft, the vertical pole guide ring 101 may be tangled when a plurality of vertical pole guide rings 101 overlap as shown in FIG. A material having a certain degree of rigidity is preferable. In the eaves flag display device of this embodiment, a hollow pipe having an outer diameter of 6 mm formed of vinyl resin and closed in an annular shape is used as the vertical pole guide ring 101.

3. Upper Rotating Member The upper rotating member 20 is not particularly limited as long as it is provided on the top of the vertical pole 10 so as to be horizontally rotatable. As shown in FIG. 2, the upper rotating member 20 includes a support shaft 21 that is inserted into the vertical pole 10 and a flange 22 that is hooked on the upper end of the vertical pole 10. And a tip shaft 23 erected upward from the flange 22. A weight 24 is fixed to the lower end of the support shaft 21 so that the upper rotating member 20 does not wobble. The flange 22 may be directly mounted on the upper end of the vertical pole 10. However, in the flag flag raising device of this embodiment, the flange 22 is mounted on the thrust bearing 13 fixed to the upper end of the vertical pole 10, and the upper rotating member 20. The friction when rotating is reduced. Thereby, it is possible to smoothly rotate the upper rotating member 20 horizontally.

4). Horizontal Arm The location where the horizontal arm 30 is provided is not particularly limited as long as it is a portion that performs horizontal rotation integrally with the upper rotating member 20. In the flag display device of this embodiment, the horizontal arm 30 has its base end fixed to the outer peripheral surface of the distal end shaft 23 of the upper rotating member 20 as shown in FIG. Further, the portion near the tip of the horizontal arm 30 and the tip of the tip shaft 23 of the upper rotating member 20 are connected by a hanging strap 25 so that the tip of the horizontal arm 30 is not lowered by the load of the flag 100. . A wind receiving plate (not shown) or the like may be attached to the horizontal arm 30. Thereby, the upper side rotation member 20 can be horizontally rotated more smoothly. In addition, it is possible to further increase the advertising effect of the flag 100 by displaying a shop name or the like on the wind receiving plate.

5. As shown in FIG. 1, the lifting rope 40 is guided from the lower side to the upper side along the vertical pole 10, passes through the horizontal arm 30, and hangs from the center of the horizontal arm 30 at one end thereof. It is fixed to the upper edge. The other end of the lifting rope 40 is wound around a lifting rope winding means 50 fixed to the lower rotating member 60. For this reason, the upper edge of the flag 100 rises when the other end of the lifting rope 40 is wound up by the lifting rope winding means 50, and descends when the other end of the lifting rope 40 is drawn out from the lifting rope winding means 50. It is supposed to be. As shown in FIGS. 1 and 2, the lifting rope 40 includes a lifting rope guide ring 104 provided at the inner end of the upper edge support bar 102 attached along the upper edge of the flag 100, and a lower part of the flag 100. It passes through an elevating rope guide ring 105 provided at the inner end of the lower edge support bar 103 attached along the edge so that the upper and lower edges of the flag 100 are not inclined. The upper and lower edges of the flag 100 are kept in a straight line by the upper edge support bar 102 and the lower edge support bar 103.

  By the way, the term “rope” generally refers to ropes and ropes that are made by combining fibers and steel wires, but the terms “elevating rope” and “suspending rope” in the flag flag lifting device of the present invention are: The present invention is not construed as being limited to this embodiment, and includes various wires having necessary tensile strength and flexibility, such as wires and chains. In the flag raising apparatus according to the present embodiment, the elevating rope 40 uses a wire in which a metal wire is covered with a resin. The lifting rope 40 has a small diameter of about several millimeters and excellent flexibility, but also excellent tensile strength. Moreover, since the circumference | surroundings are coat | covered with resin, it is the thing excellent also in rust prevention property and corrosion resistance.

6). Lifting rope winding means The lifting rope winding means 50 is not particularly limited as long as it can perform a winding operation for winding the lifting rope 40 and a feeding operation for feeding the lifting rope 40. For example, the lifting rope winding means 50 includes a handle (not shown), a winding drum (not shown) that rotates in conjunction with the handle, and a lock mechanism (not shown) that locks the handle or the winding drum so as not to rotate. ). Thereby, the winding rope 40 is wound around the winding drum by rotating the handle in the forward direction, and the lifting rope 40 is fed out from the winding drum by rotating the handle in the reverse direction. It becomes possible to do. However, as will be described later, in order to automatically raise and lower the flag 100 according to the wind speed, it is preferable that the lifting rope winding means 50 be electrically operated. In the eaves flag display device of this embodiment, as shown in FIG. 3, as the lifting rope winding means 50, a device including a motor 51 and a winding drum 52 that rotates in conjunction with the motor 51 is employed. ing. The lifting rope winding means 50 can be remotely operated by a remote controller (not shown).

  As the motor 51 used for the lifting rope winding means 50, any of a direct current motor and an alternating current motor can be used as long as it can rotate forward and backward. As will be described later, when a commercial power source (AC100V or AC200V in Japan) is used as a power source necessary for driving the hoisting rope winding means 50, an AC motor is used without interposing a converter or the like. However, it is preferable because the lifting rope winding means 50 can be driven. In addition, an AC motor has a longer life and is easier to maintain than a DC motor. If a motor with a brake mechanism in which the drive shaft is locked so as not to rotate when stopped is adopted as the motor 51, the winding drum 52 can be prevented from rotating when the motor 51 is stopped. Therefore, even if the suspension ropes 80 and 81 (see FIG. 1) to be described later are not provided, as long as the weight balance between the lower rotation group and the flag is maintained well, the lower side is only lowered by the lifting rope 40. It is also possible to support the rotating member 60 in a suspended state.

7). Lower Rotating Member The lower rotating member 60 is not particularly limited as long as the lower rotating member 60 is provided below the vertical pole 10 so as to be horizontally rotatable. In the flag raising apparatus according to the present embodiment, as shown in FIG. 3, the lower rotating member 60 includes a flange 61 provided with a through hole 61 a for passing the lifting rope 40 and the hanging rope 80, and a lifting rope winding. A housing box 62 for housing the take-up means 50 and the like, a first pipe 63 that covers the outer periphery of the vertical pole 10 while connecting the bottom surface of the flange 61 and the top surface of the housing box 62, and the ceiling surface of the housing box 62 The second pipe 64 covers the outer periphery of the vertical pole 10 while being connected to the inner bottom surface. A through hole for inserting the vertical pole 10 is formed in the upper plate and the bottom plate forming the flange 61 and the storage box 62. For this reason, the flange 61 and the accommodation box 62 are in a state of being pivotally supported by the vertical pole 10 so as to be horizontally rotatable. The flange 61, the storage box 62, the first pipe 63, and the second pipe 64 are all fixed integrally, and can be rotated horizontally around the vertical pole 10 as a center. As shown in FIG. 4, the flange 61 is paired with the stopper 82 to support both ends of the lower edge support bar 103 in the flag flag 100 when the flag flag 100 is lowered, and the lower edge of the flag flag 100 is horizontally aligned. It has the function to keep If the suspension rope guide ring (large) 106 may be caught by the stopper 82 when the flag 100 is lowered, the stopper 82 may be formed in a wide flange shape like the flange 61, It is advisable to further extend the tip of an arm (an arm extending in the horizontal direction from the lower rotating member 60) that fixes the lower end of the hanging rope 81.

  The lower rotating member 60 may be attached to the vertical pole 10 through a thrust bearing (not shown) as with the upper rotating member 20, but in the flag flag raising device of this embodiment, as shown in FIG. Further, it is supported in a state suspended from the horizontal arm 30 by the lifting rope 40. As a result, the frictional force that the lower rotating member 60 receives from the vertical pole 10 is greatly reduced, and the lower rotating member 60 can be smoothly rotated horizontally. However, in this case, the total weight of the lower rotating group that horizontally rotates integrally with the lower rotating member 60, such as the lower rotating member 60 and the lifting rope winding means 50, is equal to the total weight of the flag 100. Set so that it becomes (when hanging ropes 80 and 81 to be described later are not provided) or set to be equal to or more than the total weight of the flag 100 (when to provide hanging ropes 80 and 81 to be described later). It is necessary to keep. A weight (not shown) or the like may be fixed to the lower rotating member 60 as necessary.

  The accommodation box 62 preferably contains control means (programmable controller, etc., not shown) for processing a top dead center detection signal, a bottom dead center detection signal, a strong wind signal, a strong wind release signal, or the like, which will be described later. Thereby, not only the total weight of the lower rotation group can be gained, but also the control means and the like can be prevented from being exposed to wind and rain. Also, the storage box 62 includes a lift switch (not shown) for forcibly raising and lowering the flag 100 regardless of a strong wind signal, a strong wind release signal, etc., and a transmission / reception device for exchanging signals with the outside by radio. (Not shown), control devices (not shown) such as relays, timers, and counters, and wirings (not shown) for electrically connecting the components can be accommodated.

8). The suspension rope lower rotating member 60 may be suspended only by the lifting rope 40. In this case, in order to keep the lower rotation group suspended, the total weight of the flag 100, A device for maintaining the weight balance between the flag 100 and the lower rotation group is required, for example, the total weight of the lower rotation group must be set equal. For this reason, in the flag hoisting device of this embodiment, as shown in FIG. 1, the suspension ropes 80 and 81 for connecting the horizontal arm 30 and the lower rotation group independently of the lifting rope 40 are provided. Provided. Therefore, the lower rotation group is in a state where the height thereof is regulated by the suspension ropes 80 and 81. Further, even if the total weight of the flag flag 100 and the total weight of the lower rotation group are not equal, the lower side is sufficient if the total weight of the lower rotation group is made heavier than the total weight of the flag flag 100. Since the rotation group can be supported in a suspended state, it is possible to reduce the trouble of adjusting the weight balance between the flag 100 and the lower rotation group.

  Although only one suspension rope 80, 81 may be provided, it is preferable to provide a plurality of suspension ropes 80, 81. This not only further reduces the burden on the suspension ropes 80 and 81, but also facilitates the interlocking of the upper rotating group including the upper rotating member 20 and the lower rotating group including the lower rotating member 60. Thus, the difference between the angle at which the upper rotation group rotates horizontally and the angle at which the lower rotation group rotates horizontally can be reduced. Therefore, it is possible to make it difficult for the lifting rope 40 and the hanging ropes 80 and 81 to be twisted. As shown in FIG. 1, the hanging flag display device of this embodiment is provided with two hanging ropes 80 and 81. Among these, the suspension rope 80 connects the vicinity of the proximal end of the horizontal arm 30 and the vicinity of the fulcrum of the lower rotation group (location supported by the vertical pole 10), and the inner edge ( It is arranged closer to the inside (closer to the vertical pole 10) than the edge close to the vertical pole 10. On the other hand, the suspension rope 81 connects the vicinity of the tip of the horizontal arm 30 and the vicinity of the outer end of the lower rotation group (location farthest from the location pivotally supported by the vertical pole 10). The outer edge (the edge on the side far from the vertical pole 10) is arranged outside.

  In the anchor flag display device of this embodiment, the suspension rope 81 is passed through a suspension rope guide ring (large) 106 attached to the outer edge of the anchor flag 100 at a predetermined interval, as shown in FIG. ing. For this reason, when the flag 100 is displayed, the outer edge of the flag 100 can be kept straight along the hanging rope 81. In addition, the suspension rope 81 includes a suspension rope guide ring (small) 107 provided at the outer end of the upper edge support bar 102 attached along the upper edge of the flag flag 100, and the lower edge of the flag flag 100. The lower edge support bar 103 attached in this way is passed through a hanging rope guide ring (small) 108 provided at the outer end of the lower edge support bar 103 so that the upper and lower edges of the flag 100 are not easily tilted. The suspended rope guide rings (small) 107 and 108, together with the above-described lifting rope guide rings 104 and 105, contribute to keeping the upper and lower edges of the flag 100 horizontal. A weight (not shown) or the like may be attached to the lower edge of the flag 100. As a result, it is possible to prevent the lower edge of the flag 100 from rising.

  By the way, the suspension ropes 80 and 81 can use not only ropes and ropes made of fibers and steel wires, but also wires and chains, like the lifting rope 40. In the flag raising apparatus according to the present embodiment, the hanging ropes 80 and 81 are made of a wire in which a metal wire is covered with a resin. The hanging ropes 80 and 81 have a small diameter of about several millimeters and excellent flexibility, but also excellent tensile strength. Moreover, since the circumference | surroundings are coat | covered with resin, it is the thing excellent also in rust prevention property and corrosion resistance. For the suspension ropes 80 and 81, an electric wire for supplying electric power to a wind speed detecting means 90 (strong wind detecting means and strong wind release detecting means) described later, an electric wire for supplying electric power obtained by the solar cell module 110, or the like is used. Or along these wires.

9. The top dead center detecting means and the bottom dead center detecting means As shown in FIG. 1, the flag display device according to the present embodiment detects that the top edge of the flag flag 100 has reached the top dead center. The top dead center detecting means 70 for issuing the detection signal and the bottom dead center for detecting that the upper edge of the flag 100 has reached the bottom dead center and issuing the bottom dead center detection signal as shown in FIG. Point detection means 71 is provided. The top dead center detection signal emitted from the top dead center detection means 70 and the bottom dead center detection signal emitted from the bottom dead center detection means 71 are input to a control means (not shown). When the top dead center detection signal is input, the control means outputs a winding operation stop signal for stopping the winding operation to the lifting rope winding means 50, and when the bottom dead center detection signal is input. The lifting rope control means 50 is set to output a feeding operation stop signal for stopping the feeding operation. For this reason, after the upper edge of the flag 100 reaches the top dead center, the lower rotation group (the part that horizontally rotates integrally with the lower rotation member 60 such as the lifting rope winding means 50 and the lower rotation member 60). Is not raised, and the elevating rope 40 is not loosened after the upper edge of the flag 100 reaches the bottom dead center.

  The top dead center detecting means 70 and the bottom dead center detecting means 71 are not particularly limited as long as they can detect that the upper edge of the flag 100 has reached the top dead center or the bottom dead center. As the top dead center detecting means 70 and the bottom dead center detecting means 71, a limit switch that reacts when a predetermined position of the flag 100 or the lifting rope 40 comes into contact, or a predetermined position of the flag 100 or the lifting rope 40 enters the detection range. For example, a photoelectric switch or a proximity switch that reacts with the. In the kite flag display device of this embodiment, limit switches are used as the top dead center detecting means 70 and the bottom dead center detecting means 71 as shown in FIGS. The limit switch used as the top dead center detecting means 70 and the limit switch used as the bottom dead center detecting means 71 are the same (the mounting direction is upside down).

  The limit switches used as the top dead center detecting means 70 and the bottom dead center detecting means 71 will be described in more detail. In the following, for convenience of explanation, only the top dead center detection means 70 will be described, and the bottom dead center detection means 71 will not be described, but the bottom dead center detection means 71 is the same as the top dead center detection means 70. A configuration can be employed. As shown in FIGS. 6 and 7, the top dead center detecting means 70 detects an actuator 70b in which a lifting rope insertion groove 70a for inserting the lifting rope 40 in the vertical direction is formed at the tip, and the fall of the actuator 70b. And a main body 70d provided with a switch 70c. The actuator 70b has a tip that moves up and down around the rotation axis at the base end. When no external force is applied to the tip, a spring (not shown) is provided around the center shaft. ) And the like, as shown in FIG. 6, the tip is maintained in a floating posture. In this state, the switch 70c is not pushed down by the actuator 70b and is in an off state.

  When the lifting rope 40 is wound in the direction of the thick arrow from the state of FIG. 6, the upper edge of the flag 100 (see FIG. 1) on the lifting rope 40 reaches the top dead center. At this time, the detected portion 40a for detecting the top dead center provided at the top dead center detecting means 70 at a position where the top dead center detecting means 70 enters the lifting rope insertion groove 70a is lowered to enter the lifting rope insertion groove 70a of the actuator 70b. However, since the outer diameter of the detected portion 40a for detecting the top dead center is set to be larger than the width of the elevating rope insertion groove 70a, the detected portion 40b for detecting the top dead center is caught by the actuator 70b. . The tip of the actuator 70b is pushed down by the top dead center detecting portion 40a that continues to descend, and as shown in FIG. In this state, the switch 70c (see FIG. 6) is in an on state by the contact of the actuator 70b. The fact that the switch 70c is turned on is input to a control means (not shown) as a top dead center detection signal. Thereby, when the upper edge of the flag 100 reaches the top dead center, the lifting rope winding means 50 can be surely stopped.

  The detected part 40a for detecting the top dead center provided on the lifting rope 40 is not particularly limited as long as it is in the form of being caught by the actuator 70b. In the flag raising apparatus according to this embodiment, the top dead center detection target portion 40a is provided by caulking a substantially cylindrical metal member to the lifting rope 40 as shown in FIGS. The upper end and the lower end of the detected portion 40a for detecting the top dead center are formed in a tapered shape. This has the effect of facilitating the lower end of the detected portion 40a for detecting the top dead center to enter the elevating rope insertion groove 70a of the actuator 70b. Further, from the state of FIG. 1 until the upper edge of the flag flag 100 is lowered to the state of FIG. 2, or from the state of FIG. 2 until the upper edge of the flag flag 100 is raised to the state of FIG. In the meantime, the detected portion 40a for detecting the top dead center must pass through the elevating rope guide rings 104 and 105 provided in the flag 100. Thus, the detected portion 40a for detecting the top dead center is used. By forming the upper and lower ends in a tapered shape, it is possible to prevent the detected portion 40a for detecting the top dead center from being caught by the lifting rope guide rings 104 and 105.

10. Wind speed detection means (strong wind detection means and strong wind release detection means)
As shown in FIG. 1, the wind flag display device of this embodiment is provided with wind speed detection means 90. This wind speed detecting means 90 is a strong wind detecting means for detecting that the wind speed has exceeded a predetermined value S ₁ and generating a strong wind detection signal, and that the wind speed has fallen below a predetermined value S ₂ (S ₂ ≦ S ₁ ). And also serves as a strong wind cancellation detection means for generating a strong wind cancellation detection signal. The strong wind detection signal and the strong wind release signal generated by the wind speed detection unit 90 (strong wind detection unit and strong wind release detection unit) are input to a control unit (not shown). When the strong wind detection signal is input, the control means outputs a lifting operation start signal for starting the lifting operation to the lifting rope winding means 50. When the strong wind release detection signal is input, the control means winds the lifting rope winding. A winding operation start signal for causing the means 50 to start the winding operation is set to be output.

By the way, in the Meteorological Agency's wind class, “strong wind” means a wind whose wind speed is 28 knots (about 13.9 m / s) or more and less than 33 knots (about 17.1 m / s). The “strong wind” in “means” and “strong wind release detecting means” is not limited to this. Predetermined values _{S 1} and predetermined value _{S 2} is appropriately determined depending on the size of Noborihata 100, usually set to 3~15m / s. In this case, predetermined values S ₁ and the predetermined value S ₂ may be set to the same value but, in this case, when the wind speed the wind is blowing close to predetermined values S _1, strong wind detection signal and strong winds There is a possibility that the flag 100 malfunctions, for example, when the release detection signal is frequently issued and the flag 100 is repeatedly raised and lowered. Therefore, a predetermined value S ₂ is predetermined value lower than S _1, when specifically is set to a low value of about 1 to 5 m / s preferred.

The predetermined values S ₁ and a predetermined value S ₂ to the same value, or Noborihata 100 which can occur when set to a value close malfunction, rather than always get the wind from the wind speed detecting means 90, a timer (not It is also possible to prevent this by acquiring it at predetermined intervals using (omitted) or the like. In this case, the period for detecting the wind speed is not particularly limited. However, if this period is too short, the flag 100 is liable to malfunction, and if it is too long, the responsiveness of lifting and lowering the flag 100 with respect to the wind speed is deteriorated. For this reason, the period for detecting the wind speed is normally set to 1 to 30 minutes, preferably 5 to 20 minutes. Nobori flag hoisted apparatus of the present embodiment detects the wind speed every 15 minutes by the wind speed detecting means 90, emits a strong wind detection signal when the wind speed at that time exceeds the predetermined value S _1, the wind speed at that time is given if less than the value S ₂ are set to emit strong wind release detection signal. For example, the timer automatically raises the flag 100 when the business start time is reached and automatically lowers the flag 100 when the business finish time is reached. It can also be used. The place where the timer is provided is not particularly limited, but is provided inside the storage box 62 of the lower rotating member 60 in the flag display device of the present embodiment.

  The place where the wind speed detecting means 90 is provided is not particularly limited. It may be provided in the flag display device, or may be provided at a location distant from the flag flag display device so as to emit a strong wind detection signal or a strong wind release detection signal wirelessly or by wire. The latter configuration is suitable for use in large stores that display a large number of flag flags. This makes it possible to manage the lifting and unloading of a large number of flag flags in an integrated manner. When the wind speed detection means 90 is provided in each flag display device, it is preferable to attach the wind speed detection means 90 at a position as high as possible of the flag display device. Thereby, it is possible to easily detect the wind speed.

As long as the wind speed detecting unit 90 can detect that the wind speed has reached the predetermined value S ₁ and the predetermined value S ₂ , the wind speed detecting unit 90 may not be able to continuously measure the wind speed that changes over time, and may be related to the wind direction. Information may not be obtained. Examples of the wind speed detecting means 90 include a cup-type anemometer, a windmill-type anemometer, an ultrasonic anemometer, a Pitot tube anemometer, and the like. In the flag flag display device of this embodiment, a device using the principle of the total pressure pipe (a kind of Pitot tube) is used as the wind speed detecting means 90 to reduce the manufacturing cost of the flag flag display device. It is also possible to make the wind speed detecting means 90 small and inconspicuous. This configuration is suitable for the case where the wind speed detecting means 90 is provided in the flag display device. On the other hand, when the wind speed detecting means 90 is provided at a location away from the flag display device, it is preferable to employ a wind speed measuring device such as a cup anemometer or a windmill anemometer that can measure the wind speed regardless of the wind direction.

  The full pressure pipe employed as the wind speed detecting means 90 in the flag flag raising device of this embodiment will be described in more detail. As shown in FIG. 8, the total pressure pipe is composed of a wind guide pipe 91 for introducing wind and a wind speed detector 92 for detecting the wind speed of the wind introduced into the wind guide pipe 91. . The air guide port 91a (total pressure port) of the air guide tube 91 is normally directed to the windward side. In order for the air guide port 91a to always face the windward side, such as the upper rotating member 20 (see FIG. 1) and the lower rotating member 60 (see FIG. 1), where the wind rotates horizontally. The total pressure pipe may be attached so that the air guide port 91a is oriented from the front end to the base end of the horizontal arm 30 (see FIG. 1). In order to make it easier to detect the wind speed, it is preferable to provide a total pressure pipe on the upper rotating member 20 (see FIG. 1) located higher than the lower rotating member 60 located lower.

As shown in FIG. 8, the wind speed detection unit 92 in the total pressure pipe is formed in a thick tubular shape extending in the up-down direction, and the support shaft 93 disposed in the up-down direction and the support shaft 93 are disposed therein. A disc-shaped wind receiving plate 94 that is pivotally supported so as to freely move up and down is accommodated. For this reason, the height of the wind receiving plate 94 changes according to the wind speed (more precisely, the total pressure) of the wind that has entered the air guide pipe 91. The position of the wind receiving plate 94 increases as the wind speed increases. In the flag raising apparatus according to the present embodiment, when the point P _{1 on} the end surface of the wind receiving plate 94 comes into contact with the point Q ₁ on the inner peripheral surface of the wind speed detecting unit 92, a strong wind detection signal is generated. the point P ₁ is adapted to high winds release detection signal is issued in contact with a point Q ₂ on the inner circumferential surface of the wind speed detecting unit 92 in the. The contact between the point P ₁ and the point Q ₁ and the contact between the point P ₁ and the point Q ₂ may be determined mechanically, but are usually determined electrically.

As shown in FIG. 8, an adjustment port 92a is provided at a location lower than the wind receiving plate 94 on the peripheral wall of the wind speed detection unit 92 in the total pressure pipe. Therefore, regulating port 92a by adjusting the opening area of the wind speed (predetermined values S ₁ to the point P ₁ at the end face of the wind receiving plate 94 reaches the point Q ₁ and the point Q ₂ on the inner circumferential surface of the wind speed detecting unit 92 And the predetermined value S ₂ ) can be adjusted. The wind speed at which the point P ₁ reaches the point Q ₁ or the point Q ₂ can be increased as the opening area of the adjusting port 92a is increased, and can be decreased as the opening area of the adjusting port 92a is decreased. it can.

11. Others Examples of a power source required to drive the lifting rope winding means 50 and the wind speed detection means 90 shown in FIG. 1 include a solar battery and a commercial power source. For example, as shown in FIG. 1, a solar cell module 110 and a battery (not shown) for storing electric power obtained from the solar cell module can be provided in the flag display device. Thereby, it is possible to realize energy saving of the flag flag display device. This configuration can be suitably employed when it is desired to install a flag flag display device at an event venue or a mountain road where it is difficult to secure commercial power. The place where the solar cell module 110 is provided is not particularly limited. The solar cell module 110 may be provided on the lower rotating member 60, but in this case, the solar cell module may be shaded by the flag 100 and the vertical pole 10 due to the balance between the wind direction and the sunshine direction. For this reason, in the flag flag display device of this embodiment, the solar cell module 110 is horizontally attached to the vertical pole 10 (the tip of the tip shaft 23 of the upper rotating member 20). Thereby, it is also possible to improve the appearance of the flag display device. The place where the battery is provided is not particularly limited, but in the flag flag display device of the present embodiment, the battery is accommodated in the accommodation box 62 in the lower rotating member 60.

  However, when a solar cell is adopted as a power supply source, not only maintenance such as cleaning of the solar cell module and replacement of the battery is required, but there is a disadvantage that it is difficult to obtain a large amount of power. Therefore, in the case where it is not possible to cover only with the electric power obtained from the solar cell module 110, it is necessary to use a commercial power source. Thereby, since it becomes possible to obtain a large electric power constantly, the advertising effect of the flag 100 can be further enhanced, for example, the flag 100 is illuminated. In the drawing, for the sake of convenience of explanation, the flag display device is drawn in a form in which a solar cell and a commercial power source are used together. Whether to use a solar battery or a commercial power source is appropriately determined in consideration of the power consumption and installation location of the flag display device.

  By the way, when a commercial power source is adopted as a power supply source, the lifting rope winding means 50 and the wind speed detecting means 90 shown in FIG. 1 and an outlet (not shown) on the ground are connected to the electric wires 10c, 10d, 60c, It is necessary to connect at 60d (see FIG. 3). However, since the outlet does not move, the lifting rope winding means 50 and the wind speed detecting means 90 perform the horizontal rotation integrally with the lower rotating member 60 and the upper rotating member 20, so that the lifting rope winding means 50 and the wind speed detecting means 90 and the outlet are directly connected by the electric wires 10c, 10d, 60c, and 60d, the electric wires 10c, 10d, 60c, and 60d may be twisted or wound around the vertical pole 10. For this reason, in the flag display device of this embodiment, as shown in FIG. 3, a pair of annular electrodes 10 a and 10 b are provided at locations where the vertical pole 10 is covered with the second pipe 64 of the lower rotating member 60. A pair of brushes 60a and 60b are provided at locations corresponding to the annular electrodes 10a and 10b in the lower rotating member 60. Since the pair of annular electrodes 10a and 10b are provided over the entire circumference of the outer periphery of the vertical pole 10, the pair of annular electrodes 10a and 10b can be used regardless of the horizontal rotation of the lower rotating member 60. And the pair of brushes 60a and 60b are always in electrical contact with each other.

12 Applications The flag display device of the present invention is not particularly limited in the type of flag flag to be displayed, and various types of flags and flags from commercial ones for advertising to non-commercial ones for festivals. Can be displayed. Among them, it is suitable as a banner for advertising advertisements displayed at large retail stores such as department stores and supermarkets, amusement facilities such as game centers and pachinko stores, or event venues such as festivals and concerts. At these facilities and venues, it is common to display a large number of flag flags, so that the time required for lifting and lowering the flag flag and the time required for maintenance can be reduced. This is because the characteristics can be utilized. The flag can be used not only in a continuous plane shape but also in a net or the like having an opening. This makes it possible to reduce the resistance that the flag is subjected to from the wind. When the flag is a net, characters and figures may be directly written on the net, but a previously cut one may be pasted. Moreover, you may make it involve the cords for electrical decoration.
