The horizontal support poles are inserted into the horizontal insertion holes, and the horizontal support poles are inserted into the assembly holes provided in the vertical support poles.

[0003]

Since the above-mentioned conventional stand-up type signboard is flat and lightweight, it is easy to handle, but since its usual height is about 1.5 meters, it can be transported. However, there is a disadvantage that it cannot be loaded on a small-sized vehicle, and it may be possible to assemble it at the installation site, but it is actually extremely difficult when the installation site faces a road with frequent traffic.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vertical signboard which can be easily assembled into two folds with a simple structure.

[0005]

In order to achieve the above object, the present invention forms a cylindrical vertical insertion hole and a horizontal insertion hole at each side of a rectangular display film whose four corners are cut off, Insert the two vertical poles into the vertical insertion holes, respectively, insert the two horizontal poles into the horizontal insertion holes, respectively, and connect the horizontal poles at the joints provided on the vertical poles. The main feature is that the middle part has a fitting structure that allows insertion and removal, and that the fitting part of this vertical pole can be folded in half under the bending of the display target film when the fitting part is appropriately separated. Characterize.

As a fitting structure of the vertical pole, it is preferable to adopt a spline structure based on the engagement relationship between the projection and the vertical groove to provide a play prevention structure, and as a connecting structure of the vertical pole and the horizontal pole. , The vertical pole is provided with a vertically long hole, and the head corresponding to the vertically long hole and the shaft portion corresponding to the inner diameter of the horizontal pole are provided so that both parts are eccentric to each other. It is preferable that the tension state of the displayed film can be adjusted by selecting the mounting direction of the pin.

[0007]

[Function] In addition to cutting off the four corners, two vertical poles and two horizontal poles are provided in each vertical insertion hole and horizontal insertion hole in the rectangular display target film in which cylindrical vertical insertion holes and horizontal insertion holes are formed in each side. A flat rectangular signboard can be assembled and formed by inserting the pole and inserting the horizontal pole at the end of the horizontal pole, and when transporting and storing, the horizontal pole on one side and the vertical pole It is possible to fold it in two while the connection is released, and the fitting portion of the intermediate portion of the vertical pole is appropriately extracted and separated.

Further, the fitting structure in the middle portion of the vertical pole is spline-fitted, and free play is prevented at the fitting portion. When connecting the vertical pole and the horizontal pole, the distance between both horizontal poles is adjusted by selecting the mounting direction of the mounting pin in which the head and the shaft are formed in an eccentric relationship. Can always be set in a tense state.

[0009]

The present invention will be described in detail below with reference to the illustrated embodiments. As a signboard to which the present invention is applied, generally, as shown in FIG. 1, both sides of a rectangular synthetic resin film to-be-displayed film 1 with four corners cut off are wound in a loop shape and heat-welded to form a tubular shape. While forming the vertical insertion holes 2 and 2,
Similarly, the upper and lower sides are wound in a loop shape and heat-welded to form cylindrical horizontal insertion holes 3 and 3, and additionally, two relatively long vertical poles 4 and 4 and two relatively short horizontal poles. 5 and 5 are provided to insert the vertical poles 4 and 4 and the horizontal poles 5 and 5 into the vertical insertion holes 2 and 2 and the horizontal insertion holes 3 and 3 of the display film 1, respectively, and The horizontal poles 5 and 5 are connected at a connecting portion provided close to the top and a connecting portion provided near the lower portion, whereby the lower portion of the vertical poles 4 and 4 is applied to the supporting legs 6 and 6 so as to be flat. Adopt a rectangular signboard.

As a special constitution of the present invention for the above-mentioned type, a metal tube made of aluminum or the like is adopted as each of the vertical poles 4, and the separated portions are separated in the vicinity of the center of the vertical poles 4. The spline fitting portion 7 is adapted to be removably connectable, and the fitting portion 7 has a specific structure as shown in FIGS. 2 and 3, for example, as shown in FIGS. A shaft member 9 having a synthetic resin fitting shaft 8 with a collar adapted to the inner diameter of the vertical pole 4 is fixed to one of the portions, and projections 10 and 10 are provided on the outer circumference of the fitting shaft 8. At the other end, receiving grooves 11, 11 corresponding to the projections 10, 10 of the fitting shaft 8 are provided in the deep portion by notching in a gradually narrow shape, and these projections 1
It is desirable that the 0, 10 and the receiving grooves 11, 11 form a spline fitting structure that is immovable and slidable in the axial direction.

As a connecting portion between the vertical pole 4 and the horizontal pole 5, for example, as shown in FIGS. 4 and 5, a metal tube of aluminum or the like having a diameter smaller than that of the vertical pole 4 is adopted as the horizontal pole 5, and the vertical pole is also used. In the shaft 4, vertically elongated holes 12, 12 are bored along the axis of the left-right direction, and separately, an elliptical head 13 matching the vertically elongated hole 12 and a shaft portion 1 matching the inner diameter of the horizontal pole 5.
4 is provided with an eccentric relationship with the vertical pole 4, and the horizontal pole 5 is contacted with the vertical elongated hole 12 portion of the vertical pole 4 in a T-shape. From the outer side of the vertical hole 12 and the inner hole of the horizontal pole 5.

In assembly, the vertical poles 4 and 4 and the horizontal poles 5 and 5 are inserted into the vertical insertion holes 2 and 2 and the horizontal insertion holes 3 and 3 in the film to be displayed 1, respectively.
The mounting pins 15, 15 may be inserted into the connecting portions of the vertical and horizontal poles 4, 5 facing each other in a T shape, and the mounting direction of the shaft portion 14 should be selected up and down when the mounting pins 15 are inserted. Thus, the distance between the two lateral poles 5 and 5 is adjusted so that the displayed film 1 can be always set in a tensioned state.

When carrying or storing, as shown in FIG. 6, after removing the mounting pins 15 and 15 connecting the lower horizontal pole 5 and the fitting portions 7 of both vertical poles 4 and 4, By folding the display target film 1 in the separated portion of the fitting portion 7, the signboard is folded in two. When using, the fitting portions 7 of both vertical poles 4 and 4 are inserted and fitted, and the lower horizontal pole 5 is connected to the vertical poles 4 and 4.
Under the condition that it corresponds to the vertically long holes 12 and 12 of 4,
All that is required is to insert the mounting pins 15, 15.

The lower horizontal pole 5 in the folded state
In order to prevent the swinging of the horizontal pin 5 and to prevent the mounting pins 15 and 15 that have been pulled out from being lost, as shown in FIGS.
The same vertical elongated holes 16 and 16 for temporary fixing are formed at positions appropriately above 2, 2 and 12, so that the fitting portions 7 of both vertical poles 4 and 4 are pulled out at the time of folding, and then the lower horizontal pole 5 is formed. Are suitably connected at the upper longitudinal holes 16 for temporary fixing.

The material of the display film 1 is not limited to the synthetic resin film, and may be a cloth or a composite structure of the cloth and the synthetic resin film, and the materials of the vertical poles 4 and the horizontal poles 5 are not limited to metal tubes. Synthetic resin may be used. When the vertical pole 4 is made of synthetic resin, the shaft member 9
Can be molded into the same body as the vertical pole 4.

[0016]

As described above, according to the present invention,
The following effects can be obtained. a. The vertical poles 4 and 4 have a fitting structure that can be freely inserted and removed in the middle portion, and in a state where the fitting portion 7 of the vertical pole is appropriately separated, it can be bent under the bending of the display target film 1. As a result, it is possible to easily fold and restore it in half with a simple structure.
Therefore, it is convenient because it can be loaded in a small vehicle that can be turned around in a folded state and can be carried on a complicated and narrow road to install or remove signboards at various places. b. Since the fitting portion 7 of the vertical poles 4 and 4 has the spline fitting structure, the vertical pole 4 itself is not twisted by this, and in combination with the connection with the horizontal pole 5, it is an assembly type structure. Nevertheless, it can be constructed accurately and firmly.

C. As a connecting structure of the vertical pole 4 and the horizontal pole 5, a vertical elongated hole 12 is bored in the vertical pole 4 along the horizontal axis, and an elliptical head 13 matching the vertical elongated hole 12 and an inner diameter of the horizontal pole 5. The mounting pin 15 is formed in an eccentric relationship with the shaft portion 14 that conforms to the above. Since the mounting pin 15 is inserted, the distance between the lateral poles 5 and 5 can be adjusted based on the selection of the vertical position of the shaft portion 14 when the mounting pin 15 is inserted. The display target film 1 can be always kept in an appropriate tension state by adjusting the expansion and contraction due to the manufacturing error or the temperature change due to the season.
