Description

The present invention relates to a flag support device. More specifically, a horizontal support bar that supports the upper edge of the banner is attached to a mounting member fixed to the upper end of the pole that supports the flag, and is in a protruding state that projects forward at a substantially right angle to the pole; It is pivoted so that it can rotate within a range of angles when folded along the pillar, making it easy to handle when in use and when not in use, and also prevents damage when the flag is blown by strong winds. This invention relates to a difficult-to-use banner support device.

Conventionally used nobori support devices require a number of loop pieces (commonly called chichi) attached to one vertical edge and the upper edge of the nobori. The pole and horizontal support bar must be inserted through this and attached to the pole and horizontal support bar, and the loop piece must be attached to the pole and horizontal support bar when the flag is not needed, such as when transporting or storing the flag support device. It has to be removed from the lateral support bar or the column, and in either case there is a problem in that it requires time-consuming and troublesome work.

In view of this problem, a flag support device according to Patent Document 1 has been provided. In this flag support device, a support portion that supports a horizontal support bar is rotatably connected to a mounting body provided at an upper end of a column by a support shaft that is located on the axis of the column. The horizontal support bar is configured to be lockable at least at a position substantially perpendicular to the support column, and is configured to be folded in a direction along the support column.

Since the lateral support bar is locked at a position substantially perpendicular to the column, as described in paragraphs 0037 and 0038 of Patent Document 1, the lateral support bar is substantially perpendicular to the column. The flag is held stably in the direction of , and the flag is attached to the column and the horizontal support bar as required. Further, when the banner support device is not used, the locking state is released, the horizontal support bar is folded to a position along the column, the flag is also folded, and the banner is wrapped around the column. For example, the bulk can be reduced and the handling of the flag support device can be facilitated. The next time you use it, you just need to rewind the flag, rotate the horizontal support bar in a direction approximately perpendicular to the column, and lock it with the lock pin in the same way as above, making it easy to assemble when reusing it. can be done.

However, the banner support device according to Patent Document 1 locks the horizontal support bar in a state that is substantially perpendicular to the column, so when the banner is blown by strong winds, the load is concentrated on the support shaft and There was a risk of damaging the spindle.

Furthermore, when the flag is blown up by strong winds, the loop pieces provided on the flag move along the pillars and the flag is rolled up, and the wind strongly hits this rolled up part of the flag. As a result, an excessive load was applied to the support column in this area, and there was a risk that the support support would break.

Patent Document 2 shows another embodiment of a flag support device in which the horizontal support bar is configured to be rotatable. This flag support device has been proposed in an attempt to further improve the workability when attaching the loop piece to the horizontal support bar in the flag support device according to Patent Document 1, and includes a rotating body provided at the upper end of the column. A rotating body that supports the horizontal support bar is rotatably connected to the mounting body by a support shaft located on the axis of the support column. The rotating body has a first claw part, a second claw part, and a horizontal rod holding part, and when the nobori support device is used, the rotating body is held so that the first claw part is the first stop part. By rotating the horizontal support bar until it is stopped, the horizontal support bar can be held in a direction substantially perpendicular to the support column (in a horizontal state when the support column is in an upright state). Furthermore, in order to attach the loop-shaped attachment piece to the horizontal support bar when assembling the flag support device, the horizontal support bar is rotated upward to a standing state in which it is approximately in the same straight line as the support column. In this raised state, the second claw portion and the second stop portion are engaged to prevent (lock) the horizontal support bar from further rotating.

By attaching the loop-shaped attachment piece to the horizontal support bar, the flag can be attached to the column and the horizontal support bar as required, but in the event of strong winds, an upward load is applied to the horizontal support bar. When the horizontal support bar is actuated, the horizontal support bar rotates upward and assumes the above-mentioned raised state, and further rotation is inhibited (locked).

When the flag is blown by strong winds in this state, the loop-shaped attachment piece provided on the flag moves along the pillar, causing the flag to be rolled up and wrapped around the top of the pillar and the horizontal support bar. Something happens.

As a result, there is a possibility that a load is intensively applied to the support shaft, causing damage to the support shaft, and there is also a possibility that the lock portion is damaged and cannot perform a normal locking action. In addition, in strong winds, there is a risk that the wind will strongly hit the rolled up part of the flag or the wrapped part, damaging the support shaft, and there is also a risk that an excessive load will be applied to the horizontal support bar and cause it to break. In extreme cases, there was a risk that the pillars might break. In addition, when the flag is wrapped in this way, it is difficult to unravel the wrapping.

In addition, in this way, the flag support devices according to Patent Documents 1 and 2 have a problem in that when a flag is blown up by strong winds, there is a risk that the load will be concentrated on the support shaft and damage the support shaft. The moving parts had to be made thick and sturdy, which caused the problem of complicating the structure of the nobori support device.

As a result, when the rotary cylinder body 41 is fitted into the split groove portion 17, the first fitting protrusion 61 and the first fitting recess 60 are fitted, as shown in FIG. As shown in FIGS. 9, 2, and 6, the bearing holes 35, 35 (FIG. 2) and the pivot hole 51 (FIG. 6) match in the fitted state. As a result, when the rotating cylinder 41 is rotatably pivoted 13 as described above, the fitting protrusion 61 and the fitting recess 60 are fitted into each other as shown in FIGS. 4 and 6. As long as the shaft 33 is inserted into the bearing holes 35, 35 and the pivot hole 51, the bearing holes 35, 35 and the pivot hole 51 will automatically match as shown in FIG. Thus, the work of configuring the pivot structure can be easily and reliably performed.

In this embodiment, as shown in FIG. 4, the holding means 14 includes a first engaging portion 62 provided on the proximal end portion 19 of the horizontal support bar 11 and a first engaging portion 62 provided on the dividing groove portion 17. and a second engaging portion 63 that can be engaged with the first engaging portion 62 in an abutting state.

The first engaging portion 62 is configured as upper edge portions 66, 66 of both side surfaces 65, 65 of the proximal end portion 19, and the second engaging portion 63 is configured as , 16 protrudes inward from the dividing groove portion 17, covers the upper edge portions 66, 66 from above, and is elastically pressed against the upper edge portions 66, 66 (elastically pressed). It is configured as a protrusion 69, 69 (to be engaged with). The upper edge portions 66, 66 are configured as inclined surfaces 70, 70 with cut corners, for example, as shown in FIG. , is configured to be able to engage with the inclined surfaces 70, 70 in an abutting state.

In the protruding state A in which the lateral support bar 11 protrudes forward at a substantially right angle with respect to the support column 5, the proximal end portion 19 is connected to the split groove as shown in FIGS. 3 and 4. It is in a state where it is inserted into 17. As shown in FIG. 5, this fitting is performed by causing the split groove portion 17 to elastically expand when the base end portion 19 of the support bar 11 is rotated in the opposite direction F2 (FIG. 7). be exposed. That is, as shown in FIG. 7, the horizontal support bar 11 is rotated in the opposite direction F2 about the pivot shaft 33. This rotation is performed when the tips 69a, 69a (FIG. 5) of the opposing protrusions 69, 69 abut against both side surfaces 65, 65 of the base end portion 19 of the lateral support bar 11. The rotation in the reverse direction F2 is performed by elastically expanding the split groove portion 17 as shown in FIG. Finally, as the split groove portion 17 elastically returns, the first and second engaging portions 62 and 63 are brought into contact with each other, as shown in FIG. 4(A). The support bar 11 remains unrotatable until a certain load or more is applied upward (that is, a load sufficient to elastically expand the groove portion 17). In other words, the horizontal support bar 11 is held by the holding means 14.

In this embodiment, the proximal end portion 19 is elastically held between the compatible wall portions 16, 16 and is tightly fitted into the split groove portion 17. In the fitted state, the lower surface portion (in this embodiment, the inclined lower surface 59 of the inclined surface protruding portion 56 shown in FIGS. 7 and 10) 20 of the proximal end portion 19 is The groove bottom portion of the split groove portion 17 (in this embodiment, the peripheral portion of the upper end of the fitting recess portion 60) 21 (FIGS. 4, 7, and 10) comes into contact with the groove bottom portion. In this fitted state, the proximal end portion 19 is held by the holding means 14. This makes it impossible for the horizontal support bar 11 to rotate downward.

Also, according to the present invention, when the flag is blown by a strong wind, the load acting on the horizontal support bar 11 is distributed to two points, the pivot shaft 33 and the groove bottom 21, as described above. The banner support device 1 according to the present invention can be This allows for a simple structure.

As described above, when a load of a certain amount or more is applied upward to the horizontal support bar 11 held by the holding means 14, the holding is released. There are two ways to release the hold.

In the first mode, when the flag support device 1 is not in use, the horizontal support bar 11 is held by hand and rotated upward from the protruding state A in the forward direction F1, as shown in FIG. This is a case where the holding is released by moving the object. Even after the holding is released in this way, by continuing to rotate the horizontal support bar 11 in the forward direction F1, the horizontal support bar 11 passes through the upright state C shown in FIG. It exhibits the compact folded state B (indicated by the two-dot chain line in FIG. 2). By wrapping the flag 2 around the support post 5 in the folded state B in this way, the volume of the flag support device 1 can be reduced, making it easy to store and transport. On the other hand, when using the banner support device 1, the banner 2 is rolled back, the horizontal support bar 11 is rotated upward in the opposite direction F2, and the proximal end portion 19 is fitted into the split groove portion 17. .

This fitted state is held by the holding means 4 by elastically engaging the first and second engaging portions 62 and 63. When in use, simply by rotating the flag support device 1 in this manner, it can be assembled into a usable state easily and quickly.

The second aspect is when a load above a certain level is applied upward to the horizontal support bar 11 when the flag 2 is blown by a strong wind with a wind speed of, for example, about 10 to 15 m/sec. For example, the side loop piece 4 (FIG. 1) provided on the flag 2 moves upward along the pillar 5, causing the flag 2 to be rolled up, and the flag 2 to be attached to the top of the pillar 5 or to the side. This is a case where the horizontal support bar 11 is wrapped around the support bar 11, and the rolled-up portion is strongly hit by wind upwards, and a load of the above-mentioned value or more is applied upward to the horizontal support bar 11. If the horizontal support bar 11 continues to rotate due to the action of a strong wind even after the holding is released in this way, the rotation will not be locked in the middle and will return to the free state in the positive direction. By doing this, the horizontal support bar 11 can go from the upright state C to the folded state B along the support column 4.

Next, the procedure for attaching the flag 2 to the flag support device 1 will be explained. One method is to first set the horizontal support bar 11 in the protruding state A in which it protrudes forward at a substantially right angle to the support column 5, as shown by the solid line in FIG. In the protruding state A, the proximal portion 19 of the lateral support bar 11 is supported by the pivot shaft 33 and supported from below by the groove bottom 21, as described above. In the protruding state, the proximal end portion 19 is held by the holding means 14, and the lateral support bar 11 maintains the holding state unless a load above a certain level is applied upwardly to it, as described above. do.

With the horizontal support bar 11 projecting in this manner, the side loop pieces 4 attached to the vertical edge 3 (FIG. 1) and the upper edge 9 (FIG. 1) of the banner 2 The upper loop piece 10 is connected to the side loop piece 4 and the upper loop from the tip of the horizontal support bar 11 in order from the lower end of the vertical edge 3. It is attached by inserting the piece 10 through it. Then, the upper loop piece 10a located on the distal end side of the horizontal support bar 11 is fixed to the retaining portion 45.

In this embodiment, the side loop piece 4 and the upper loop piece 10 can be attached to the horizontal support bar 11 and the support column 5 relatively smoothly with less catching. The reason for this is that, in this embodiment, as shown in FIGS. The series of upper ends 53 of the bearing piece portion 32 are formed to be substantially flush with each other, and the front and rear end portions 46 and 47 of the rotating cylinder 41 are formed to have a semicircular arc shape; Since the rear edge portions 37, 37 of the upper ends of the bearing pieces 32, 32 are formed as arcuate convex surfaces, the side loop piece 4 attached to the support column 5 can be attached to the horizontal support bar 11 and the support column 5. This is because the connecting portion 73 can be passed through the connection portion 73 without getting caught, and can be moved toward the support column 5 side.

Another method for attaching the flag 2 to the flag support device 1 is to set the horizontal support bar 11 to the upright state C extending upward along the support column 5, as shown in FIG. and the horizontal support bar 11 is in a straight line. In this state, all of the side loop pieces 4 and the upper loop pieces 10 are connected to each other in order from the upper end of the lateral support bar 11, and the lateral support bar 11 and the support column 5 are connected to the side loop pieces 4 and the upper loop pieces. 10 to attach it to the support column 5 and the horizontal support bar 9.

In addition, when removing the flag 2 from the flag support device 1, such as when replacing the flag 2, the upper loop piece 10 and the side loop piece 4 are attached to the support column 5 and the side loop piece 4 by the reverse operation. Remove from support bar 11. At this time, in this embodiment, as shown in FIGS. 2 and 3, since the lower edge portions 38, 38 of the bearing pieces 32, 32 are formed as quarter-arc convex surfaces, the side loop pieces 4 can be moved to the side of the horizontal support bar 11 by passing through the connecting portion 73 between the horizontal support bar 11 and the support column 5 without getting caught there.

FIG. 1 shows the usage state of the flag support device 1 to which the flag 2 is attached in this manner. In this state of use, the horizontal support bar 11 is in a two-point supported state, supported by the pivot 33 and supported from below by the groove bottom 21, as shown in FIGS. 3 and 6. Therefore, when the flag 2 is blown by a strong wind, the load acting downward on the horizontal support bar 11 is distributed to two points: the pivot shaft 33 and the groove bottom 21. Therefore, unlike in Patent Documents 1 and 2, there is no fear that a load is intensively applied to the pivot shaft 33 and the pivot structure is damaged.

Further, when the wind speed becomes strong, for example, about 10 to 15 m/sec in the above-mentioned use condition, a load of above the certain value acts upward on the horizontal support bar 11, and the holding by the holding means 14 is released. There are cases where this occurs. When the horizontal support bar 11 is rotated significantly upward in a state where the holding is released in this way, the horizontal support bar 11 that supports the upper edge 9 of the nobori 2 moves toward the pillar 5, as described above. Since it can rotate in the free state toward the folded state B (FIG. 2) along the horizontal support bar 11 and the pivot structure, it is possible to protect the horizontal support bar 11 and the pivot structure from wind pressure.

This point will be explained in comparison with the case in Patent Document 2. As described above, the horizontal support bar according to Patent Document 2 is configured such that the second pawl portion and the second stop portion engage with each other in a state in which the horizontal support bar is rotated upward to a standing state, so that the horizontal support bar can no longer be moved further. Rotation is prevented (locked). Therefore, when a flag is blown up by strong winds and becomes wrapped around the upper part of the pillar or the horizontal support bar, the wind will strongly hit the wrapped portion upward. As a result, an excessive load is applied to this portion, which may cause the horizontal support bar to break or damage the pivot structure of the horizontal support bar. On the other hand, according to the present invention, the horizontal support bar 11 is rotated in the free state without being locked in the middle, so that the flag 2, which has been blown up by strong winds, can be rotated by the horizontal support bar 11. 11, the horizontal support bar 11 can be rotated to the folded state B along the support column 5 after passing through the upright state C. Therefore, according to the present invention, the load applied to the horizontal support bar 11 can be reduced, the horizontal support bar 11 and its pivot structure can be protected from wind pressure, and the support column 5 can be protected. Thereby, there is no possibility that the horizontal support bar 11 will break or the support column 5 will break.

It is held by the friction between the surface parts 79 and 79, and when an external force of a certain amount or more is applied upward to the horizontal support bar 11, the first and second engaging parts 62 and 63 are held. It is also possible to employ a configuration in which the holding is released by engaging and disengaging. In addition, the first and second engaging portions 62 and 63 may be configured to be able to elastically engage in a concave-convex fitting state and to be able to engage and disengage elastically.

(3) The horizontal support bar 9 may protrude in a substantially horizontal state when the support column 4 is viewed in a vertical state.

(4) The structure of the pivot 13 for making the horizontal support bar 9 rotatable in the angular range between the protruding state A and the folded state B is achieved by inserting the pivot 33 therethrough. The present invention is not limited to this, and a pivot connection such as a concave-convex fitting method may be used.
