By the way, in order to indicate a dangerous zone, etc., it is preferable to provide a sign indicating why the rope is provided together with the rope indicating the boundary. For example, using a freshly painted sign with a rope can add credibility to the bounds indicated by the rope, increasing the effectiveness of the sign and the rope.

In view of such a situation, a banner flag is fixed to a supporting device as described in Patent Document 1. Among them, fixing by wrapping the flagpole of the flag on the support with tape is particularly common.

However, attaching the flag using the above method has various problems, such as the fact that the stick and the support are stained with the adhesive, and that it is difficult to remove.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a support that allows a wire rod such as a rope and a rod-like member such as a flag to be easily removed.

The present invention for solving the above problems includes an elongated shaft portion and a support portion projecting substantially perpendicularly to the axial direction of the shaft portion, wherein the support portion extends in the axial direction of the shaft portion. It is a supporting tool that has a perforated portion that is perforated substantially parallel to the support member, and the perforated portion supports at least one of the rod-shaped member and the wire while being inserted.

With such a configuration, the wire rod can be inserted into and supported by the support portion, and the rod-shaped member can be supported and erected simply by inserting it into the perforated portion. It is possible to provide a support from which a banner can be easily removed.

In a preferred embodiment of the present invention, a plurality of perforations are provided along the direction in which the shaft extends.

With such a configuration, the rod-shaped member can be erected by the plurality of support portions, so that the rod-shaped member is less likely to tilt.

A support according to each embodiment of the present invention will be described below with reference to the drawings. The description of the present invention takes the form of first describing the form and characteristics of each component of the present invention, then describing how to use the present invention, and finally describing modifications of the embodiment.
Moreover, the code|symbol X represents a support tool in these figures.
However, each embodiment shown below is an example of the present invention, and the present invention is not limited to each of the following embodiments.

<<First Embodiment>>
FIG. 1 shows a perspective view of a support X according to a first embodiment of the invention.
The support X is composed of an elongated shaft portion 1 and a support portion 2 protruding substantially perpendicularly to the axial direction of the shaft portion 1 .

Axial portion 1 is a metal member, and is formed such that its axis extends substantially linearly.
A tip portion 11 is provided at the lower portion of the shaft portion 1 so as to become sharper toward the lower end. A disk-shaped upper end portion 12a having a large diameter is provided.
The shaft portion 1 is preferably made of a solid metal member, but may be made hollow if the diameter is large.

The tip portion 11 is sharp enough to allow the support X to penetrate the ground, and is provided integrally with the shaft portion 1 .
1 is sharpened toward the center of the shaft portion 1, it may be sharpened toward the side surface of the shaft portion 1. As shown in FIG. In the former case, the support can be easily driven into the ground perpendicularly, and in the latter case, since the tip of the pointed end portion 11 can be formed sharper, it becomes easier to drive into the hard ground.

Further, as shown in FIG. 2(a), the upper end portion 12a is formed integrally with the shaft portion 1, but may be separately attached by welding. Moreover, the upper surface of the upper end portion 12 a is preferably horizontal with respect to the axial direction of the shaft portion 1 .
Since the upper end portion 12a increases the surface that can be hit when driving, it becomes easier to drive the support X into the ground.
The upper end portion 12a may be omitted, and the upper end of the shaft portion 1 may simply be present.

A cap 12b may be attached to the upper end of the shaft portion 1 as shown in FIG. 2(b).
The cap 12b is a component that can be fitted and attached to the uppermost end of the shaft portion 1, and is composed of a cap main body 121 and an elastic member 122. As shown in FIG.

The cap main body 121 has a hollow interior and is fitted to the shaft portion 1 here.
When the shaft portion 1 is hollow, the cap body 121 has a projecting shape and is attached to the shaft portion 1 by being screwed.

The elastic member 122 is an elastic member that is fixed and attached to the upper surface of the cap main body 121, and has the effect of suppressing repulsion from the support X when the support X is driven into the ground. As a result, the impulse applied to the support X can be efficiently applied downward, and the driving operation of the support X becomes simple.
The elastic member 122 is preferably provided parallel to the axial direction of the shaft portion 1 when the cap 12b is attached, so that the support X can be easily penetrated vertically into the ground.

As shown in FIG. 1, the support portion 2 is a substantially disk-shaped member that is welded and fixed substantially perpendicular to the axial direction of the shaft portion 1, and is provided substantially parallel to the axial direction. and a cut portion C provided substantially perpendicular to the plane in which the perforated portion H is included.

In addition, in this embodiment, two support portions 2 are provided along the direction in which the shaft portion 1 extends. As a result, the perforations H respectively provided in the support portion 2 are positioned on the same straight line.
Three or more supporting portions 2 may be provided, and a plurality of supporting portions 2 may be provided in different directions perpendicular to the shaft portion.

The perforated portion H is a hole formed in a circular shape from the center of the support portion 2, and supports a rod-shaped member F2, which will be described later, in a state in which it is inserted.
Further, the inner peripheral surface of the support portion 2 formed by the perforated portion H is chamfered so as to be parallel to the shaft portion 1 .

The method of forming the perforated portion H is not limited to perforating the support portion 2, and may be formed by bending the support portion 2 or by casting.

The notch portion C is a notch provided from the symmetrical position of the connection point with the shaft portion 1 in the support portion 2 to the perforated portion H, and has a width that allows insertion of a wire rod R, which will be described later.
The width of the cut portion C is preferably narrower than the outer diameter of the rod-shaped member F2 so that the rod-shaped member F2 does not come off.

The supporting portion 2 may be formed of a member having elasticity.

FIG. 3(a) shows a top view of the support portion 2 in this embodiment. In this figure, the connection point between the shaft portion 1 and the support portion 2 is omitted.

As shown in FIG. 3( a ), the cut portion C is configured to become wider from the perforated portion H toward the outside of the support portion 2 . By configuring in this way, it is possible to facilitate the insertion of the wire rod R into the perforated portion H and prevent the wire rod R from falling off from the support portion 2 .

In addition, in order to prevent the wire R from falling off from the support portion 2, the position of the cut portion C is provided near the connection point between the shaft portion 1 and the support portion 2, as shown in FIG. 3(b). It is desirable. With such a configuration, even if the wire R is inserted into the perforated portion H so as to be hooked, and the wire R is pulled away from the support X, it can be prevented from falling out of the cut portion C.

More preferably, one of the ends of the support portion 2 on both sides of the notch C may be provided with a hook member that closes the notch C. As shown in FIG.
The hook member can be pushed toward the perforated portion H, and is provided so as to return to a position closing the cut portion C by an elastic action when the pushing force is not applied.
This makes it possible to easily insert the wire rod R into the perforated portion H like a so-called carabiner and prevent it from falling out.

FIG. 4 is a perspective view showing a state in which the support X is driven into the ground and the flag F is installed.

As shown in FIG. 4, the banner F includes a display portion F1 which is a thin cloth member for displaying information, a rod-shaped member F2 which supports the display portion F1 from the side, and a suspension portion F3 which suspends the display portion F1 from above. and consists of

The rod-shaped member F2 is an elongated flag pole made of plastic, and is configured such that the length in the axial direction can be changed by combining a plurality of hollow members so that they can be fixed in an arbitrary positional relationship. there is Thereby, the length of the rod-shaped member F2 can be adjusted according to the driving depth of the support X. As shown in FIG.

Further, the rod-shaped member F2 is inserted into the two support portions 2 provided on the support X at the same time, thereby erecting in substantially the same direction as the direction in which the shaft portion 1 is driven into the ground.
As a result, the banner F can be supported along the support X.

In addition, by making the perforated portion H and the rod-like member F2 have substantially the same circumferential shape, the rod-like member F2 can be fitted and fixed to the support portion 2 so that it is difficult to move relative to the support portion 2 .

Furthermore, by making the cross-sectional shape of the perforated portion H and the rod-shaped member F2 elliptical or square, the rotation of the rod-shaped member F2 is suppressed, and the display portion F1 can always be oriented in an arbitrary direction.

FIG. 5 is a schematic diagram showing how the wire R is supported by the supporting portion 2. As shown in FIG.

As shown in FIG. 5, the wire rod R extends from below the supporting portion 2 to the perforated portion H, and is supported by the supporting portion 2 by being brought into contact with the upper portion of the supporting portion 2 from the perforated portion H. As shown in FIG.

The wire R may be a wire, a rope (especially conspicuous one such as a tiger rope), or a strip such as a PE tape, and the minimum width of these members is preferably smaller than the width of the cut portion C.

In addition, since the cut portion C is provided substantially perpendicular to the plane including the perforated portion H, the wire rod R supported as described above is less likely to drop out of the cut portion C.

FIG. 6 is a perspective view showing how the banner F and the wire rod R are simultaneously supported by the support X. As shown in FIG.

As shown in FIG. 6, the perforated portion H is sized so that the rod-like member F2 can be inserted while the wire rod R is inserted.

The method of using the present invention will be described below with reference to the drawings. The present invention is used by users with the goal of creating boundaries.
In addition, the mode of use is not limited to the description below, and the order thereof may be changed.

First, the user hits the upper end portion 12a with a hammer or the like while the tip portion 11 of the shaft portion 1 is thrust into the ground, thereby driving the support X into the ground. The user performs the above work on a plurality of supports X at appropriate intervals.

Next, as shown in FIG. 5, the user places a part of the wire rod R along the notch C and inserts it into the hole H as it is.
This is performed for each of the plurality of supports X.

Next, the user inserts the rod-like members F2 into the two support portions 2 at the same time, as shown in FIG.
This is performed for each of the plurality of supports X.

Finally, as shown in FIG. 6, the user pulls the wire R with an appropriate force to tension the wire R and tie the end of the wire R to the shaft portion 1 .
By the operation described above, the user can form a boundary with the support X.

Also, the user can recover the support X by performing the reverse operation.

Further, by inserting the rod-shaped member F2 behind the wire R, the cut portion C is closed by the rod-shaped member F2, and the wire R can be prevented from falling off.

Moreover, if the boundary has an inner side and an outer side, it is preferable to provide the support X so that the cut portion C faces the outer side of the boundary. As a result, a pressing force in the direction of the notch C is less likely to act, so that the inserted wire R is less likely to fall off. In particular, it is desirable to configure the corners of the boundary in this way.

With the above configuration, it is possible to provide the support X from which the wire R such as a rope and the rod-like member F2 such as a banner can be easily removed.

The supporting portion main body 21 is provided with a perforated portion H in the center, and the perforated portion H is formed so that the rod-like member F2 and the wire rod R can be inserted. In the present embodiment, since there is no cut portion C, there is no possibility that the wire rod will come off from the cut portion C.
The wire R is inserted through the hole H from the lower surface to the upper surface, and is supported by being brought into contact with the upper surface of the supporting portion main body 21 .

The joint portion 22 is fixed to the shaft portion 1 by welding, and provides a space between the shaft portion 1 and the support portion main body 21 . Thereby, when the supports X are stored in a bundle, it is possible to prevent the support main bodies 21 from interfering with each other.

Further, since the wire rod R can be wound around the joint portion 22, the end portion of the wire rod R can be easily fixed.
