Description

  The present invention relates to a display device, and more particularly, to a display device that is easily noticeable by a visual change in a surface pattern (excellent in eye catching effect).

Conventionally, there has been a display device in which a pattern resembling a so-called “moire shape” is moved by driving a motor to give a visual change to the view from the front (see, for example, Patent Document 1).
JP 7-210100 A

  However, the moiré in the device disclosed in the above publication is an artificially drawn moiré (moire-like shape), and a sheet-like object on which the moiré is drawn is rotated by driving a motor. As a result, a visual change occurs, but it cannot be denied that the change is periodic, that is, patterned. In addition, a battery is indispensable because it is necessary to drive the motor and rotate the seat for visual change.

  The problem to be solved in the display apparatus of the present invention is that the visual change of moire occurs infinitely, and therefore the eye catching effect is remarkably improved, and because of the visual change of moire, the battery (power source) is not necessarily used. Is to provide a display device that is not necessary.

  The display device according to claim 1 is a display device including an upper support portion extending in a lateral direction and a display fabric suspended from the upper support portion, wherein the display fabric is overlapped with each other. 1 woven fabric and a second woven fabric, the woven fabric has a thickness of warp and weft of 2.5 to 8.5 tex, and a high light transmittance of 30 to 90%. The second woven fabric made of a thin fabric and located at least on the back side of the first woven fabric is glossy, and at least one woven fabric moves under an external pressure such as an air flow. Thus, the shape of the moire generated in the state in which the two woven fabrics are overlapped is sequentially changed.

  The display device according to claim 2, wherein the upper and lower support portions respectively extend in the lateral direction, the upper end is held by the upper support portion, and the lower end is held by the lower support portion. The display fabric includes a first woven fabric and a second woven fabric superimposed on each other, and the woven fabric has warp and weft thicknesses of 2. The second woven fabric is made of a thin fabric having a high light transmittance of 5 to 8.5 tex and an aperture ratio of 30 to 90%, and at least the second woven fabric located on the back side from the first woven fabric has gloss. The at least one woven fabric is moved by receiving an external pressure such as an air flow, so that the shape of the moire generated in the state in which the two woven fabrics are overlapped is sequentially changed. Features.

  A display device according to claim 3 is the display device according to claim 1 or 2, wherein the woven fabric is formed by plain weaving and / or silk weaving.

  The display device according to claim 4 is the display device according to any one of claims 1 to 3, wherein the first woven fabric and the second woven fabric have the same desired shape at positions facing each other. Are each printed.

  The display device according to claim 5 is the display device according to any one of claims 1 to 4, wherein the upper support portion has a cylindrical shape, and a slit extending in a longitudinal direction is provided on a circumferential surface thereof. With the slit facing upward, the upper end portion of the first woven fabric is inserted into the slit from the front side of the upper support portion, and the upper end portion of the second woven fabric is inserted into the upper support portion. The first woven fabric and the second woven fabric are inserted into the slit from the rear side, whereby each of the first woven fabric and the second woven fabric is held by the upper support portion. The upper support portion having a shape can be installed apart by a depth dimension.

  The display device according to claim 1, wherein the thickness of the warp and the weft is 2.5 to 8.5 tex (25 decitex to 85 decitex), and the aperture ratio is 30 to 90%. Since the posting fabric is configured, and at least the second woven fabric is glossy, there is an effect that moiré is remarkably exhibited. Therefore, it is possible to provide a display device that is excellent in design effect and easily noticeable (excellent in eye catching effect).

  Not only the flow of air, wind pressure, or artificial (mechanical) operation causes an external force to be applied to at least one woven fabric, which occurs when the two woven fabrics are overlapped. Since the shape of the moire to be changed sequentially and the changed shape is infinite, the design effect becomes even more prominent, and the advertisement and message written on the display fabric are more easily noticed.

  The display device according to the second aspect has the following operational effects in addition to the operational effects of the display device according to the first aspect. That is, the moire phenomenon formed by overlapping two woven fabrics disappears when the gap between the two woven fabrics is too far away, and it is necessary to maintain a certain distance. In the display device according to claim 2, since the upper end is held by the upper support portion and the lower end is held by the lower support portion, even if external force such as air flow or wind pressure is applied to the woven fabric, There is no possibility that either one or both of the woven fabrics will be turned up and a large distance between them will be generated, and the disappearance of moire can be prevented.

  Further, by holding the display fabric at the upper and lower ends (only the upper and lower ends) of the two woven fabrics constituting the air, air enters between the two woven fabrics (a range that does not hinder the formation of moire). It is possible to create a slightly swollen state, and this can be added to the design effect.

  The display device according to the third aspect has the following operational effects in addition to the operational effects of the apparatus according to the first and second aspects. That is, since a woven fabric plain and / or knit using warps and wefts having a thickness of 2.5 to 8.5 tex is used, a woven fabric having a thickness (50 μm to 200 μm) in which moire is more likely to occur is provided. The display fabric can be easily obtained, and is more effective as a display device. Further, even if the display fabric is made large (wide), it does not become so heavy, and there is no concern that the material of the upper support part for hanging the display fabric is limited.

  The display device according to the fourth aspect has the following operational effects in addition to the operational effects of the apparatus according to any one of the first to third aspects. That is, since the same shape (pattern) is printed at mutually opposed positions in the first woven fabric and the second woven fabric having high light transmittance (high opening degree), these shapes (pattern) If the position is slightly displaced, the viewer is given the illusion that it is a 3D image. As a result, the display device can be more effectively and easily seen by the human eye.

  The display device according to the fifth aspect has the following operational effects in addition to the operational effects of the apparatus according to any one of the first to fourth aspects. In other words, the generation of moire requires that the first woven fabric and the second woven fabric be separated to some extent (distance). In the display device according to claim 5, the first woven fabric and the second woven fabric can be set apart from each other by the size (depth dimension) of the upper support portion having the slits. By using the support portion, the shape of the generated moire can be changed variously.

  If the woven fabric is similarly held with respect to the lower support part, it is more effective in that the shape of the moire can be changed variously by using the lower support part having different dimensions.

Woven fabric [warp and weft]
The yarn thickness of the woven fabric in the display device of the present invention needs to be 2.5 tex to 8.5 tex (25 decitex to 85 decitex) in order to make the moiré expression remarkable and beautiful. If it is less than 2.5 tex, not only the moiré expression will be remarkable but also the strength may be insufficient. Also, if it exceeds 8.5 tex, it is necessary to reduce the number of yarns in order to increase the aperture ratio in order to make moiré manifestation remarkable, which not only leads to insufficient strength, but beautiful moiré may not be expected. There is. More preferably (the range in which a more prominent and beautiful moiré is expressed) is 2.5 to 6.5 tex, and further preferably 2.5 to 4.5 tex.

[Opening ratio (%): 100-Fiber occupation ratio]
Moreover, in order to make moiré expression remarkable, it is necessary to increase the light transmittance, and it is necessary to set the opening ratio of the woven fabric to 30 to 90%. More preferably (the range in which moiré is more prominently exhibited) is 40 to 80%, and further preferably 50 to 70%.

The aperture ratio (%) is a value obtained by subtracting the fiber occupancy from 100, and the fiber occupancy (%) is an area ratio occupied by fibers constituting the ground structure. That is, if it shows as an area ratio which the fiber which comprises the ground organization per inch square (6.45 cm < ² >) occupies, a fiber occupation rate will be computed by the following formula.

N: Number of yarns for each fiber type constituting one inch square (pieces / 6.45 cm ² )
d: Thread diameter (thickness, cm) for each of the constituent fiber types
d ': Diameter (thickness, cm) of another thread at the crossing point in the ground texture
L: The length (cm) of one thread for each fiber type constituting one inch square: 2.54 when the threads are orthogonal. If the yarn is curved, measure the fiber length between 1 inch and take the value. N: Number of crossover points within 1 inch square. Σ: Calculate for each type of yarn used such as warp and weft. Sum it up.

[Weaving method]
Examples of a method for obtaining a woven fabric (weaving method) include plain weave, silk weave, entangled weave, and organdy. Above all, it is easy to manufacture and the weight per unit area of the woven fabric that is finally obtained is relatively light, so it can be easily swayed by external force such as air flow and wind pressure. It is preferable that the woven fabric is a plain weave and / or a knit weave because the moire phenomenon is likely to be sequentially changed by the external force.

  In addition, either one of the two sheets can be a plain woven cloth and the other can be a woven cloth of the woven weave. However, considering the effective generation of the moire phenomenon (variety of moire), both of the two sheets are woven. It is best to use a woven fabric.

[Color of woven fabric]
The color of the first and second woven fabrics may be black, dark brown, dark gray, brown, dark blue such as ultramarine blue, or light color such as white, yellow, light green, light blue, etc. In other words, it is preferably a dark color such as black or dark gray in that the moiré that appears is clearly reflected.

  Hereinafter, although one Example of the display apparatus of this invention is given and demonstrated, this invention is not limited by this.

  FIG. 1 is a perspective view of the display device (10), and FIG. 2 is an exploded perspective view thereof. The display device (10) has an upper support portion (14) having a hanging string (12) having a grip portion (12a) at both ends, a lower support portion (16), and a vertically long posting. It consists of a fabric (18).

  Each of the upper support portion (14) and the lower support portion (16) is made of a cylindrical material such as a synthetic resin or metal pipe, and a slit for sandwiching the display fabric (18) on its peripheral surface ( 15) is provided in the longitudinal direction.

  The posting fabric (18) is obtained by a weaving cloth, and three woven fabrics (from the front side, the first woven fabric (18a), the second woven fabric (18b), the third woven fabric ( 18c)).

  The first woven fabric (18a) and the second woven fabric (18b) are woven with dark-colored warp and weft such as black and dark brown. The thickness of the warp and weft is about 3 tex (30 Decitex), the aperture ratio (100-fiber occupancy) is approximately 60%, and the thickness is approximately 70 μm, but is not limited thereto. Each of the woven fabrics (18a) and (18b) is made of glossy polyester fabric, acetate fabric, or Teflon fabric (Teflon is a registered trademark of DuPont, polytetrafluoroethylene). The desired same design (shape) is printed (screen printed) at positions opposite to each other in the two woven fabrics (18b).

The third woven fabric (18c) is densely woven with light-colored warps and wefts such as white and yellow, and is drawn on the first woven fabric (18a) and the second woven fabric (18b). The position corresponding to the design (shape) is removed and the desired message is written. The thickness of the warp and weft of the third woven fabric (18c) is approximately 15 tex (150 dtex) and the aperture ratio is approximately 10% , but is not limited thereto.

  These three woven fabrics (first woven fabric (18a) to third woven fabric (18c)) are held by the upper support portions (14) and (14) and the lower support portion (16). A method of holding the three woven fabrics (the first woven fabric (18a) to the third woven fabric (18c)) on the upper support portion (14) and the lower support portion (16) will be described below.

  That is, as shown in FIG. 3, the upper end of the first woven fabric (18a) is placed on the upper support (14) with the slit (15) provided in the upper support (14) facing upward. It is inserted into the slit (15) from the front side and sandwiched (clamped), and the upper end portion of the second woven fabric (18b) is inserted into the slit (15) from the rear side of the upper support portion (14). Hold (hold). Thus, each of the first woven fabric (18a) and the second woven fabric (18b) is held by the upper support portion (14), and the first woven fabric (18a) and the second woven fabric (18b) The upper support part (14) can be set apart by the size (depth dimension).

  Similarly, as shown in FIG. 4, with the slit (15) provided in the lower support portion (16) facing downward, the lower end portion of the first woven fabric (18a) is placed on the lower support portion. (16) is inserted into the slit (15) from the front side and sandwiched (clamped), and the lower end of the second woven fabric (18b) is formed from the rear side of the lower support portion (16) to the slit (15 ) And pinch (clamp). Thereby, each of the first woven fabric (18a) and the second woven fabric (18b) is held by the lower support portion (16), and the first woven fabric (18a) and the second woven fabric (18b). Can be set apart by the size (depth dimension) of the lower support portion (16).

  Naturally, the distance between the first woven fabric (18a) and the second woven fabric (18b) can be changed by changing the size (thickness) of the upper support portion (14) and / or the lower support portion (16). Can be changed, and the size and shape of the moire generated can be changed.

  And it hangs with the string (12) for hanging. As a result, the three woven fabrics (18a), (18b) and (18c) are superposed on each other. In this state, a moire phenomenon is generated by the first woven fabric (18a) and the second woven fabric (18b), and the first woven fabric (18a) and the second woven fabric (18b) having a high aperture ratio are transparent. The message written on the third woven fabric (18c) can be seen through. Since the display cloth (18) in the display device (10) exhibits moiré significantly, the display device (10) is excellent in design effect and easily noticeable (excellent in eye catching effect).

  When the display device (10) is in a suspended state, the display device (10) receives the external force such as the flow of air (wind from an air conditioner, separately created wind, or natural wind including building wind). One woven fabric (18a) and / or the second woven fabric (18b) moves. Thereby, the shape of the moire changes each time, and the eye catching effect on the display device (10) becomes more effective. And the publicity effect / advertising effect / advertisement effect of the message becomes remarkable.

  Moreover, since the same shape (pattern) is printed in the mutually opposing position in the 1st woven fabric (18a) and the 2nd woven fabric (18b) with a mutually high light transmittance (high opening degree), these If the design is slightly misaligned from the front, it gives the viewer the illusion that the shape (pattern) is a 3D image. As a result, the display device (10) can be more easily and easily visible to the human eye.

  If the display fabric (18) comprising the first woven fabric (18a), the second woven fabric (18b) and the third woven fabric (18c) has a vertically long shape as in the above-described embodiment, It is suitable because of the following operational effects. In other words, the display fabric (18) suspended from the upper support portion (14) has different tensions at a plurality of locations in the vertical direction (because the manner in which its own weight is applied is different). Therefore, the moire phenomenon formed by the first woven fabric (18a) and the second woven fabric (18b) is also different between the upper portion and the lower portion of the display fabric (18). If the display fabric (18) is vertically long as in the present example, the difference in the moire shape becomes significant, and a portion where a large moire appears and a portion where a small moire appears can be intentionally created. By utilizing this difference, the position of the message appearing on the third woven fabric (18c) can be devised to be an effective position.

  The display device of the present invention can be used, for example, for advertisements that also serve as decorations at department stores or shops, and for guidance at exhibitions and entertainment venues.
