Description

  The present invention relates to a flag pole constituting a frame portion of a banner.

  Conventionally, the banner has been widely used as an advertising medium such as advertisements for various events, store sales guidance, and advertisements for products. Here, there is known a banner configured by inserting a flag pole into a bag-like portion provided at an edge of a side portion of the flag (see, for example, Patent Document 1).

  That is, as shown in FIGS. 13 and 14, in the banner 51 exemplified in this document, the flagpole 53 is detachably attached to the hard tubular body 56 constituting the main body portion and the distal end portion of the rigid tubular body 56. It is mainly composed of an elastically deformable bending member 55 to be mounted. Further, the bag-like portion 52a of the flag 52 into which the flagpole 53 is inserted has a shape in which the distal end side of the insertion path of the flagpole 53 is curved.

Therefore, the flagpole 53 is inserted into the bag-like portion 52a of the flag 52 while elastically deforming the tip portion thereof in a curved shape.
Registered Utility Model No. 3015357

  However, when assembling the banner 51 having such a structure, the flag pole 53 is inserted into the bag-like portion 52a of the flag 52 while bending the leading end portion of the flag pole 53 that originally extends linearly. Therefore, the assembly work is structurally difficult. Further, the flagpole 53 inserted into the bag-like portion 52a of the flag 52 always applies a load to the flag 52 side so as to extend linearly from the bent state, so that the curve of the bag-like portion 52a of the flag 52 is curved. Tensile force (tensile force) is constantly applied to the portion that is in the vicinity and the peripheral portion thereof, resulting in a decrease in the texture (look) of the appearance of this portion and a decrease in the durability of the bag-like portion 52a.

  Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide a flagpole capable of improving the assembling workability and durability of a banner without deteriorating the appearance of the flag.

  In order to achieve the above object, a flag pole according to the present invention includes a straight insertion portion that linearly extends from the base end of one side edge of the flag toward the front end side, and one side edge of the flag from the front end of the straight insertion portion. A saddle body portion inserted into the straight insertion portion of the flagpole insertion bag portion configured in a cylindrical shape with a curved insertion portion extending in an arc shape toward the most distal portion of the head, and detachably attached to a distal end portion of the saddle body portion And an arcuate joint portion formed by bending in advance to be inserted into the curved insertion portion that is mounted and located on the leading end side of the flagpole insertion bag portion of the flag.

  In this invention, when assembling the banner, for example, insert the main body portion of the flagpole insertion bag portion provided at the edge of the flag into the straight insertion portion of the flagpole insertion bag portion, An arcuate joint portion that is curved in advance so as to correspond to the arc shape of the curve insertion portion is inserted into the curve insertion portion of the flagpole insertion bag portion. Further, the bag main body part and the joint part respectively inserted into the flag pole insertion bag part are attached to each other.

  Therefore, according to the present invention, when inserting the flagpole into the flagpole insertion bag portion, for example, there is no need to bend the tip portion of the flagpole, and the flagpole can be inserted into the flagpole insertion bag portion in a divided state. The workability when assembling the banner can be improved. Further, according to the present invention, the joint portion of the flagpole inserted into the arcuate curve insertion portion of the flagpole insertion bag portion is formed in a previously curved arc shape so as to correspond to the arc shape of the curve insertion portion. Therefore, for example, the joint portion is bent and the load caused by this is not applied to the flagpole insertion bag portion, which reduces the durability of the flagpole insertion bag portion and the periphery of the flagpole insertion bag portion. It is possible to prevent the appearance (look) of the flag from being deteriorated in the portion.

In the flagpole according to the present invention, the joint portion has a reinforcing rib protruding in the radial direction, and the height of the reinforcing rib gradually increases from the proximal end side to the distal end side of the joint portion. It is formed to be low.
According to the present invention, since the joint portion, that is, the front end portion of the flagpole is configured so that the mechanical strength gradually decreases toward the front end side, that is, when the flag is bent by the wind receiving the wind. Therefore, the durability of the flagpole can be improved.

Further, in the flagpole according to the present invention, the joint portion is composed of two parts, a first split joint portion and a second split joint portion, and the first and second split joint portions. According to the present invention, when assembling the banner, the flagpole joint portion is further divided into the arcuate curve insertion portion of the flagpole insertion bag portion. Since it can be inserted, it is possible to further improve the workability when assembling the banner. In addition, according to the present invention, it is possible to easily carry the flag poles. Here, in the state where the first and second split joint portions are attached to each other, a detent mechanism that prevents them from rotating may be added to the above-described attachment / detachment mechanism.

In the flagpole according to the present invention, a plurality of locking portions for attaching a plurality of clip devices capable of sandwiching the one side edge of the flag are provided on the joint portion and the collar body portion, respectively. It is characterized by that.
According to the present invention, since the flag can be assembled by holding the flag with a plurality of clip devices attached to the locking portion on the flag pole side, it is not necessary to insert the flag pole into the flag pole insertion bag portion of the flag. The assembly workability of the banner can be improved.

  Thus, according to the present invention, it is possible to provide a flag pole capable of improving the assembling workability and durability of the banner without deteriorating the appearance of the flag.

The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 3 is a plan view showing the distal end side joint portion of FIG. 2 in an enlarged manner. 4 is a front view showing a middle joint portion connected to the proximal end portion of the distal end side joint portion shown in FIG. 2, and FIG. 5 shows the distal end joint portion shown in FIG. 3 and FIG. It is sectional drawing which shows the state in which the intermediate | middle splice part was connected in detail. Furthermore, FIGS. 6-8 has each shown the AA sectional drawing, BB sectional drawing, and CC sectional drawing of the front end side joint part shown in FIG. FIG. 9 is a cross-sectional view taken along the line DD of the connection portion between the tip side joint portion and the middle joint portion shown in FIG.

  As shown in FIG. 1, the banner 1 according to this embodiment is inserted with a support stand 7 having a cylindrical portion 7 a serving as a base for installation on the ground or the like, and a posture standing on the cylindrical portion 7 a of the support base 7. It consists of a flagpole 3 to be worn and a cloth flag 2 held on the flagpole 3. The flag 2 is formed in a band shape, and includes a flag pole insertion bag portion 2a configured in a cylindrical shape on one side edge thereof, that is, an end edge of the side portion. The flagpole insertion bag portion 2a includes a straight insertion portion 2b extending linearly from the base end of one side edge of the flag 2 toward the front end side, and the leading end of the one side edge of the flag 2 from the front end of the straight insertion portion 2b. And a curved line insertion portion 2c extending in an arc shape.

  The flag pole 3 is made of, for example, a resin material such as ABS resin or polycarbonate. Moreover, as shown in FIGS. 1-4, the flag pole 3 is the hook main body part 6 inserted in the linear insertion part 2b of the flag pole insertion bag part 2a, and the curve insertion part located in the front end side of the flag pole insertion bag part 2a. It is comprised from the arc-shaped joint part 5 formed by curving beforehand inserted in 2c. Here, the joint portion 5 serves as a middle joint portion 8 as a first split joint portion constituting the base end side thereof and a second split joint portion constituting the distal end side of the joint portion main body. An attaching / detaching mechanism (dividing mechanism) 20 capable of dividing the joint portion main body is provided in two pieces with the distal end joint portion 9.

  As shown in FIG. 5, the attachment / detachment mechanism 20 that allows the intermediate joint portion 8 and the distal joint portion 9 to be attached to and detached from each other includes an insertion portion 8e and a claw portion that constitute the distal end portion 8b of the intermediate joint portion 8. This is realized by 8f and the cylindrical portion 9e and the claw engagement hole 9f constituting the proximal end portion 9a of the distal end side joint portion 9. That is, by inserting the insertion portion 8e at the distal end of the middle joint portion 8 into the cylindrical portion 9e at the proximal end of the distal end side joint portion 9 and engaging the claw portion 8f with the claw engagement hole 9f, The joint portion 8 and the tip side joint portion 9 are attached to each other. Further, as shown in FIG. 9, the attachment / detachment mechanism 20 of the joint portion 5 includes a rotation prevention mechanism 25 at a portion where the middle joint portion 8 and the tip side joint portion 9 are attached.

  That is, a projection (projection) 9 g that protrudes in the radial direction from the inner wall surface is formed on the tube portion 9 e of the distal end side joint portion 9 along the longitudinal direction of the distal end side joint portion 9. On the other hand, in the insertion part 8e of the intermediate joint part 8, a groove part (concave part) 8g in which a part of the outer shape part is recessed in the radial direction corresponds to the position of the projection part (convex part) 9g. The intermediate joint portion 8 is formed along the longitudinal direction. Therefore, in the state where the middle joint portion 8 and the tip side joint portion 9 are attached to each other, as shown in FIG. 9, the projecting portion 9g and the groove portion 8g are engaged, and the middle step joint portion 8 and the tip side portion are engaged. The joint portion 9 is prevented from rotating. Further, the protruding portion 9g and the groove portion 8g constituting the detent mechanism 25 function as a mounting guide when the middle joint portion 8 and the tip side joint portion 9 are attached (inserted) to each other.

  Further, as shown in FIG. 4, the middle joint portion 8 includes an insertion portion 8 a that is detachably attached to the cylindrical portion at the distal end of the collar body portion 6 at the base end portion. Further, the intermediate joint portion 8 has a reinforcing rib 8c protruding in the radial direction over the entire length in order to increase rigidity, and a locking portion 8d described later is predetermined in the length direction on the reinforcing rib 8c. A plurality are provided with an interval of.

  On the other hand, as shown in FIGS. 2 and 3, the tip side joint portion 9 has a substantially spherical shape at the most distal end portion so that the tip side joint portion body can be smoothly inserted into the flagpole insertion bag portion 2a. The spherical portion 9b is formed. Further, the intermediate joint portion 8 has a reinforcing rib 9c projecting in the radial direction over the entire length in order to increase rigidity, and a locking portion 9d described later is predetermined in the length direction on the reinforcing rib 9c. A plurality are provided with an interval of. Here, as shown in FIGS. 6 to 8, the height of the reinforcing rib 9 c is formed so as to gradually decrease from the proximal end side of the distal end side joint portion 9 toward the distal end side. Similarly, the reinforcing rib 8c of the middle joint portion 8 may be formed so that its height gradually decreases from the proximal end side toward the distal end side. As a result, the joint portion 5, that is, the tip portion of the flagpole 3 is configured so that the mechanical strength gradually decreases toward the tip side, so that the flag 2 is deflected by receiving the wind from the flag 2. In this case, it is possible to optimize the absorption of the load, and thereby improve the durability of the flagpole 3.

  In addition, in the flag pole 3 of the present embodiment configured as described above, when assembling the banner 1, for example, a connection is made to the straight insertion portion 2b of the flag pole insertion bag portion 2a provided at the edge of the flag. The main body part 6 with the part 5 removed is inserted, while the curve insertion part 2c of the flag pole insertion bag part 2a is formed by bending in advance so as to correspond to the arc shape of the curve insertion part 2c. The arc-shaped joint portion 5 is inserted. Specifically, the distal joint 9 divided from the middle joint 8 is first inserted into the distal end of the curve insertion portion 2c, and then the middle joint 8 is the proximal end of the curved insertion 2c. Inserted in the side. Thereafter, the main body 6, the middle joint 8, and the distal joint 9 inserted in the flagpole insertion bag 2 a are sequentially mounted.

  Therefore, according to this embodiment, when the flag pole 3 is inserted into the flag pole insertion bag portion 2a, for example, it is not necessary to bend the leading end portion of the flag pole 3, and the flag pole insertion bag is in a state where the flag pole 3 is divided. Since it can insert in the part 2a, the workability | operativity at the time of assembling the banner 1 can be improved. Moreover, in this embodiment, the joint portion 5 of the flagpole 3 inserted into the arcuate curve insertion portion 2c of the flagpole insertion bag portion 2a is curved in advance so as to correspond to the arc shape of the curve insertion portion 2c. It is formed in a shape. Therefore, for example, a load caused by the bending of the joint portion 5 is not applied to the flag pole insertion bag portion 2a of the flag 2, thereby reducing the durability of the flag pole insertion bag portion 2a of the flag 2, and the flag pole insertion bag. It is possible to prevent the appearance (look) of the flag 2 from being deteriorated in the peripheral portion of the portion 2a. Moreover, since the flag pole 3 can be divided into a plurality of parts as described above, the components of the banner 1 can be easily transported.

  Although the present invention has been specifically described above by the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, instead of the above-described embodiment, as shown in FIG. 10, a plurality of locking portions 8 d provided in the joint portion (the middle joint portion 8 and the tip joint portion 9) 5 of the flagpole 3 described above. , 9d and a plurality of locking portions (not shown) provided on the bag main body 6 may be used to form the banner 30. That is, as shown in FIGS. 10 to 12, a plurality of clip devices 31 that hold one side edge 32 a of the flag 32 are attached to the locking portions 8 d and 9 d having the hole portions of the flag pole 3. The clip device 31 includes a pair of clamp portions 41 and 42 each having a pinion portion 44 and 45 made of, for example, elastomer resin having a high frictional resistance for directly pinching the surface of the flag 32, and a pinching portion as shown in FIG. And a spring 33 that biases the clamp portions 41 and 42 in a direction in which 44 and 45 are brought into contact (pressed) with each other.

  Therefore, according to this configuration, the banner 30 can be assembled by sandwiching the flag 32 with the plurality of clip devices 31 attached to the locking portions 8d and 9d on the flag pole 3 side. There is no need to insert a flagpole into the section, and the assembling workability of the banner 30 can be improved. Further, it is not necessary to provide a flagpole insertion bag portion on the flag.
