DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an advertisement display device, and more particularly, to two advertisement display devices which are rotatable by being connected to a driving means and which are arranged parallel to each other and at a predetermined interval. A winding pipe, and a long film material on which a plurality of advertisements having a size corresponding to the interval between the winding pipes and being wound around the winding pipe are printed,
The present invention relates to an advertisement display device configured to continuously display a desired advertisement on a film material stretched between winding pipes by rotating the winding pipe by a predetermined amount.

[0002]

2. Description of the Related Art An advertising display device incorporating a long film material as described above is mainly used outdoors such as a soccer stadium and an athletic stadium.
No. 590, Japanese Unexamined Patent Application Publication No. 9-197985, Japanese Utility Model Application Laid-Open No. 3-10.
No. 5883 and Utility Model Registration No. 302138 have been proposed.

In order to maximize the advertising effect of an advertising display device incorporating such a film material, a film material stretched between two winding pipes is stretched in a state close to a plane. It is necessary to continue. There is considerable difficulty in maintaining the membrane material near a flat surface outdoors in the wind, but the tension of the membrane material is too small and the film material is loose, and conversely the tension of the film material is too large and , Which can negatively affect the viewability of your ad,
It is not preferable because of the nature of this device that an advertisement effect is obtained by an advertisement printed on a film material. Also, considering that it is necessary to ensure the visibility of the advertisement, the solution of providing a transparent cover in front of the film material is also inappropriate. Therefore, in such an advertisement display device, a mechanism for keeping the tension of the film material constant is essential.

As a means for keeping the tension of the film material constant, a clutch, a reaction spring and other mechanical means provided separately from the driving means are generally used. However, providing such a separate mechanical means unnecessarily complicates the mechanism of the advertisement display device and hinders its miniaturization, and also complicates the work for changing the tension of the film material. Tends to. In addition, in the conventional advertisement display device, since both winding pipes are driven by one driving means, both pipes are rotated by an appropriate amount while taking into account a change in the winding amount of the film material. It is difficult to perform the operation, and a complicated gear mechanism or the like is required to realize the operation.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the above-described conventional advertisement display device so that the film material can be securely held in a planar manner while being simple and compact.

[0006]

SUMMARY OF THE INVENTION The applicant of the present invention has a conventional advertisement display device, that is, is rotatable by being connected to driving means, and is arranged parallel to each other and at a predetermined interval. Two winding pipes, and a long film material wound around the winding pipes and having a plurality of advertisements printed thereon in a size corresponding to the interval between the winding pipes, In order to solve the above-mentioned problem of the advertisement display device in which a desired advertisement is continuously displayed on a film material stretched between winding pipes by rotating, the following three types of improvements are proposed. I do.

[0007] A first improvement is to provide a driving means for the advertisement display means so as to be independently rotatable in each winding pipe and to be rotatable forward and backward. If a driving means is separately provided for each winding pipe, and each winding pipe can be separately rotated in any forward and reverse directions, until mechanical means for adjusting the tension of the film material is provided. Nonetheless, the tension of the film material can be maintained in an appropriate range. Therefore, this advertisement display device has a very simple structure, and is downsized,
Thinning is also possible. Further, by enabling the drive means to separately rotate the winding pipes in the normal and reverse directions, it is possible to rotate each winding pipe by an appropriate amount while considering the change in the winding amount of the film material. As a result, more appropriate tension can be more easily applied to the film material.

In this case, the driving means may be any one provided that it is provided independently for each of the winding pipes and can be rotated forward and backward, but it is preferable to use an encoder motor as the driving means. . If an encoder motor is used as the driving means, advertisement data can be displayed simply by creating encoder motor driving data in advance in consideration of the length of the film material, the position of the printed advertisement, and the time for displaying each advertisement. This is convenient because a desired advertisement can be displayed at a desired timing without having to operate the device on site. In addition, if the encoder motor is used as the driving means, even if fine adjustment of the tension applied to the film material is required due to a change in weather or the like, a change in the rotation amount can be performed from a place remote from the advertisement display device. There is also an advantage. Further, since the rotation speed of the encoder motor can be set in a stepless manner, the tension applied to the film material can be controlled more accurately.

Next, a second improvement is to provide a guide for supporting both end portions of the film material from both front and back surfaces between the winding pipes along the longitudinal direction of the film material.
By supporting both ends of the film material stretched between the two winding pipes by such a guide, it is possible to prevent the wind from flowing from both ends of the film material to the back side thereof, thereby preventing the film material from fluttering. As a result, the flatness of the film material can be further maintained by keeping the tension applied to the film material more constant.

In this case, slits having a narrow width are formed in both guides as insertion holes into which the ends of the film material are inserted, and the thicknesses formed at both ends of the film material are larger than the widths of the slits. More preferably, a portion is provided. By doing so, it is possible to more reliably prevent the wind from flowing from both ends of the film material, and to prevent the film material from separating from the guide by locking the thick portion to the slit. Therefore, the film material can be kept more planar.
The thick portion may be formed integrally with the film material by melting the end of the film material, or may be formed by separately attaching a thick long band to the end of the film material. Is also good.

Next, a third improvement is to provide a backlight for illuminating the film material stretched between the two winding pipes from behind, and to provide a support plate formed of a transparent body on the back surface of the film material. Is provided in close proximity. When the advertisement display device is used at night, the backlight functions to raise the visibility of the advertisement printed on the film material by raising the advertisement, but the support plate formed of a transparent body is used as the backlight. By providing the film material in close proximity to the back side of the film material between the light and the film material, it is possible to reduce the deformation of the film material in the rear direction, which is most visible, while securing the illumination of the film material by the backlight, The visibility of the advertisement printed on the film material can be further improved.

Although the three improvements described above can be used alone, two or three of them can be used in any combination.
