Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns a movable advertising sheet.

``Prior art'' Conventional movable advertising sheets change the advertising screen by simultaneously moving a plurality of retractable pieces on the back side in and out from a plurality of slits in a fixed advertising sheet (Patent Application Publication No. 59-500020, International Publication No. W083). /02517).
Since such an inlet/outlet piece uses a paper or cloth advertising sheet, if it loosens, it gets caught in a plurality of slits, making it difficult to move it in and out of the same slit, resulting in malfunction or damage.

``Problems to be solved by the invention'' The purpose of this invention is to smoothly move a plurality of strip-shaped advertising sheets in and out of the plurality of slits in a fixed advertising sheet.

"Means for Solving the Problems" The present invention will be explained with reference to the reference numerals in the attached drawings showing the embodiments of the present invention, which will be described later. A variable advertising sheet device in which a plurality of parallel slits 3 are formed and each of the removable pieces 4 of a plurality of movable advertising sheets 18 arranged on the back side of the fixed advertising sheet 2 is moved in and out from the plurality of slits 3 to the front surface. Parallel guide rods 5 and 6 are arranged at the upper and lower ends of the advertising space 1,
Common supports 7 and 8 are provided at the upper and lower ends of each of the plurality of movable advertising sheets 18, and the common supports 7 and 8 are supported by the parallel guide rods 5 and 6 so as to be able to reciprocate, and , the common supports 7 and 8 are connected by a connecting rod 9, and a drive device is provided for driving the connecting rod 9 back and forth.

"Operation" Therefore, when the connecting rod is reciprocated in the horizontal direction by the drive device, the upper and lower end common supports are reciprocated in the horizontal direction along the upper and lower horizontal guide rods, and as a result, the plurality of in/out pieces passes through the plurality of slits in the fixed advertising sheet and advances from the back side to the front side, thereby switching the screen of the fixed advertising sheet to the screen of the entry/exit piece. Thereafter, the entry/exit piece passes through the slit and enters the back side, so that the screen of the original fixed advertising sheet is reproduced. It is also possible to sequentially convert a plurality of overlapping pieces into and out of three or more types of screens by sequentially moving them in and out through the slits. In such an operation, the plurality of entry/exit pieces are pulled downward by their own weight, the weight of the lower end common support, the lower horizontal guide rod, etc., and the connecting rod expands and contracts in the vertical direction due to the above pulling, thereby blocking the pulling. There is no problem, and the inlet/outlet piece never loosens.

"Example" A fixed advertising sheet 2 is formed by fixing the outer periphery of an advertising sheet to the front inner periphery of an advertising space 1 (see FIGS. 3 and 4). In this advertising sheet 2, a plurality of vertical slits 3, 3 are formed parallel to each other at regular intervals.
A plurality of movable advertising sheets 18 are arranged on the back side of the fixed advertising sheet 2. As shown in FIG. 1, this movable advertising sheet 18 has upper and lower end common support plates 7',
It has a plurality of in/out pieces 4, 4 connected to 8'. The in/out pieces 4, 4 of each movable advertising sheet 18 are arranged between the slits 3, 3 of the fixed advertising sheet 2, and overlap. The common support plates 7' and 8' have horizontal pipes 7'',
8'' to form upper and lower end common supports 7 and 8,
Both horizontal pipes 7'' and 8'' are fitted into upper and lower horizontal guide rods 5 and 6, respectively, so as to be able to reciprocate and slide. The upper horizontal guide rod 5 is provided with both ends fixed to the upper part of the advertising space 1,
The lower horizontal guide rod 6 is suspended from the lower part of the frame 1, and guided and slid in the vertical direction along the vertical inner pin 11 (FIG. 2). Then, the horizontal pipes 7'' and 8'' of the upper and lower end common supports 7 and 8 are connected by a connecting rod 9. This connecting rod 9 is made by fitting a lower rod 9' and an upper rod 9'' so that they can slide in the vertical direction, and is extendable and retractable. A plurality of sheets (six sheets) are polymerized, and the guide rods 5, 6, the common supports 7, 8, and the connecting rods 9 are provided in the advertising space 1 according to the number of polymerized sheets (FIGS. 2 and 3). The one indicated by 12 is a horizontal rack installed on the connecting rod 9, and the one indicated by 13 is the same rack 12.
14 is a forward/reverse rotating brake motor of the same pinion, 15 is a rack 12
16 is a limit switch for reciprocating sliding of the rack 12; 17 is a downward pressing spring of the lower horizontal guide rod 6; FIG. .

"Effects" Since the present invention is constructed as described above, when the plurality of in/out pieces 4 are moved in and out from the back side to the front side through the plurality of slits 3 of the fixed advertising sheet 2, there is no possibility that the in/out pieces 4 will be pulled downward and loosen. The advertising screen can be smoothly moved in and out of the slit 3 without any trouble, and the advertisement screen can be changed.
