DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a display device according to the present invention will be described below with reference to the drawings. However, the present invention is not limited to these embodiments.

FIG. 1 shows a first embodiment of the present invention. This embodiment shows the basic shape of the display device. That is, this is an example in which an existing concrete block (JIS A5406) 100 is used as an object to be fitted, and a box frame-shaped rectangular cylinder 200 fitted to the concrete block 100 is used as a display device. The display device 200 is formed to be substantially the same as or slightly larger than the outer shape of the concrete block 100. The four sides (the outer surface when fitted) of the display device 200 become the display unit 201. The display unit displays a display according to the purpose of use, for example, a warning such as parking prohibition, guidance, advertisement, and decoration display. The material of the tubular display device is preferably made of a plastic plate, but may be made of paper, metal, or the like.
A plastic plate having a predetermined thickness, which is cut into a strip shape or the like, is produced by forming folds at three locations with a predetermined size and connecting edges. As a result, it can be folded freely. In this display device, for example, a concrete block 1 in which predetermined printing and pasting (a photograph or the like) are applied to the display surface 201 and this is erected at a predetermined position is provided.
By fitting to 00, it can be mounted instantly. That is, attachment and detachment are extremely simple.

FIG. 2 shows a display device 210 formed in a box shape as a display device for fitting concrete blocks according to the second embodiment. This box-shaped display device 21
Reference numeral 0 denotes the display device 200 of the first embodiment in which the lids 211 are provided on the top and bottom surfaces, respectively. By storing and hiding the concrete block 100 inside, it is possible to enhance the decorative effect, and at the same time, it is possible to prevent the concrete block 100 from being extracted (a form suitable for permanent use). The material is preferably made of plastic. This is to withstand opening and closing. It should be noted that an irregular-shaped object such as gravel, stone, or a sand bag can be put therein as a weight. In this respect, the versatility is increased as compared with the first embodiment.

FIG. 3 shows a display device according to a third embodiment. The display device according to this embodiment has a display unit extending from the top of the display device 200 according to the first embodiment. That is, the display device 220 includes a support frame portion 221 fitted and supported on the concrete block 100,
A display portion 222 that projects upward from the support frame portion 221 to form a display surface when fitted. In addition to the structure (A) of opening and closing the quadrangular cylindrical support frame 221, the display unit 2
A structure (B) in which the opening / closing portion 22 is used is also conceivable. Regardless of the structure, when not in use, it is unfolded and made into a plate shape so that it can be stored.

FIG. 4 shows a display device 23 according to a fourth embodiment.
0 is shown. That is, as the display device 230,
It may be either a square tube (A) or a cylinder (B). Any shape can be used as long as the shape can be fitted according to the shape of the fitted object. The latter cylindrical display device 230 may be configured to be rotatable about an axis. The decorative display effect on the display surface can be enhanced.

FIG. 5 shows a fifth embodiment of the display device according to the present invention. The display device 240 can be carried while being fitted to a concrete block (JIS A5406) 100. That is, the gripping piece 2 is inserted into the space 101 at the center of the concrete block 100.
41 is projected. The pair of gripping pieces 241 are separated from the left and right side surfaces through the bottom through the gap 101 to form the block 1.
It protrudes above 00. A hole 243 for carrying is formed in each of the protruding pieces 242. Therefore, the concrete block 100 can be lifted in a well-balanced manner. As the display device 240, the four side surfaces 244 are the display unit as in the case of the first embodiment.

FIG. 6 shows a sixth embodiment of the present invention. In this embodiment, a display device 250 having the same shape as the display device according to the embodiment shown in FIG. 3 (A) is provided with a long hole 252 for carrying on the upper display unit 251. And in this case, the center C of the long hole 252 is
The concrete block 100 is shifted to one side from the center of gravity G when the concrete block 100 is stored in the display device 250. Since the side surface 253 on one side of the display device 250 has a lid-like structure that opens and closes, the center of the elongated hole 252 is shifted from the center of gravity, and the concrete block 100 is prevented from popping out when it is lowered.

FIG. 7 shows a display device according to a seventh embodiment of the present invention. According to this embodiment, the short piece 261 is formed on the upper side of the rectangular tubular display device 260 so as to extend from each side (A). The short pieces 261 prevent the concrete block 100 from falling off when the concrete block 100 is lifted. Alternatively, the folded piece 2 is provided on the side of the display device 260.
62 are extended (B). When fitted to the concrete block 100, the folded piece 262 is in elastic contact with the block outer wall surface to prevent it from falling downward. That is, no matter which display device 260 is used, each of these pieces 261 and 262
Thereby, when fitted to the concrete block 100, it is integrated with the concrete block 100 to make it easy to carry. That is, these pieces 261 and 262 serve as stoppers when detaching from the concrete block 100 downward.
Use Each of the pieces 261 and 262 serves to prevent the concrete block 100 from coming off. It is to be noted that the four side surfaces are the display portions as in the above embodiments.

FIG. 8 shows an eighth embodiment of the present invention. The display device 270 according to this embodiment is an example in which a battery 110 of a passenger car or the like is used as an object to be fitted.
An electric display material (electrically illuminated plate) 271 such as a liquid crystal is mounted on a display surface which is one side surface of the display device 270.
Alternatively, a lamp or the like may be arranged in a rectangular plate-shaped display material. Their power source is the battery 11
Set to 0. The battery 110 for disposal can be used effectively. This is because a weak current can be generated even with a discarded battery.

Further, in addition to those shown in the above embodiments, the present invention can employ the following aspects. For example, the display device (case) may have a shape that fits a part of the fitted object without fitting the whole of the fitted object. Further, as the material, in addition to the plastic plate, a soft vinyl material or the like can be processed and used. The point is that any display such as printing can be performed on the display surface. In addition, it is possible to print and engrave patterns, characters, and the like by using this as a wooden material (made of plywood or the like). Further, a part or the whole thereof may be made of rubber to secure the stopper at the time of fitting, and to take into consideration safety in a collision. Further, the display unit may be a plate material on which paper or the like is attached. A reflector, a fluorescent display plate, or the like may be attached. Further, the display section may be formed of a writable white board or the like.
In addition, the display device according to the present invention can be used by stacking it in a two-stage, three-stage, or the like, or in a box shape, a tower shape, or the like, depending on its use. Further, it can be used indoors such as a gymnasium and an exhibition hall. For indoor use, a display unit of an illuminated type is effective, and indoor power may be supplied from an outlet.
