On the peripheral edge of the screen main body 2, an edge 4 is formed by folding the screen sheet. It is also possible to form the black edge 4 so that the back side of the screen sheet is black and the back side cloth is exposed on the front surface and the screen main body 2 is surrounded by folding the peripheral edge. In this case, the image projected on the screen surface can be projected more clearly by the black edge portion 4.
　ここで、スクリーン本体２は、伸縮性を有するものであればよい。本実施形態に係るスクリーン装置１においてスクリーン本体２は、上下左右方向及び斜め方向の全てにおいて伸縮性を有することにより、あらゆる形状に変形することができる。但し、スクリーン本体２を上下、左右又は斜めの何れか一方向又は二方向にのみ伸縮性を有するものとして、拡張したスクリーン本体２の形状を使用する目的に合わせた形状とすることも可能である。 Here, the screen main body 2 only needs to have elasticity. In the screen device 1 according to the present embodiment, the screen main body 2 can be deformed into any shape by having elasticity in all of the vertical, horizontal, and oblique directions. However, it is also possible that the screen main body 2 has elasticity only in one direction or two directions of up, down, left, right, or diagonal, and the shape of the expanded screen main body 2 can be a shape suitable for the purpose of use. .
　また、スクリーン本体２は、少なくとも投影機から投射される映像を写し出すことができるものであれば他の構成によるものであってもよい。例えば、スクリーン本体２を、裏側に投射された映像を前面に映し出すものとしてもよい。また、スクリーン本体２を、スクリーンシートに対してタッチ操作を行うことを可能として、スクリーン面に表示された画像に対して書き込み等を直接行うことができるものとしてもよい。さらに、スクリーン面は、一部又は全部が透明なものであってもよい。また、スクリーン本体２の裏面側に、第二のスクリーン面や、広告等の情報を掲載する面を設けても良い。なお、スクリーン本体２は、通気性を有するものとして構成している。このため、例えば、スクリーン装置１を二つのホワイトボード間に取り付けた場合であっても、スクリーン面が風によって揺らぐことなく、綺麗な映像を映し出すことができる。 The screen main body 2 may have another configuration as long as it can display at least an image projected from the projector. For example, the screen body 2 may project the image projected on the back side to the front side. Further, the screen main body 2 may be configured so that a touch operation can be performed on a screen sheet and writing or the like can be directly performed on an image displayed on the screen surface. Further, the screen surface may be partially or entirely transparent. Further, a second screen surface or a surface on which information such as an advertisement is placed may be provided on the back surface side of the screen main body 2. The screen main body 2 is configured to have air permeability. Therefore, for example, even when the screen device 1 is mounted between two whiteboards, a beautiful image can be displayed without the screen surface fluctuating due to the wind.
　図２に示す如く、貼着部３はスクリーン本体２よりも設置面Ｐの側に突出して形成される。貼着部３は表面部材３ａと背面部材３ｂとで構成される。表面部材３ａと背面部材３ｂとによりスクリーン本体２の周縁部を挟み込んだ状態で表面部材３ａと背面部材３ｂとを結合することにより、貼着部３がスクリーン本体２に組付けられる。 貼 As shown in FIG. 2, the sticking portion 3 is formed so as to protrude more toward the installation surface P than the screen main body 2. The sticking section 3 is composed of a surface member 3a and a back member 3b. By attaching the surface member 3a and the back member 3b while sandwiching the periphery of the screen body 2 between the surface member 3a and the back member 3b, the sticking portion 3 is assembled to the screen body 2.
　貼着部３は、背面部材３ｂの内部に磁石３ｍが収容されている。貼着部３の背面に形成された貼着面３ｐは、磁石３ｍの磁力によって、例えばホワイトボードや黒板、パーテーション等の磁着可能な場所に貼り付けられる。これにより、着磁性を有する部材であれば設置面Ｐとして機能するため、スクリーン装置１の使い勝手を向上させることができる。 The sticking portion 3 has a magnet 3m housed inside the back member 3b. The sticking surface 3p formed on the back surface of the sticking portion 3 is stuck to a place where magnetism can be made, such as a whiteboard, a blackboard, or a partition, by the magnetic force of the magnet 3m. Accordingly, since the member having magnetism functions as the installation surface P, the usability of the screen device 1 can be improved.
　本実施形態においては図２に示す如く、貼着部３において設置面Ｐに貼着する貼着面３ｐは、スクリーン本体２から後方に突出して形成される。これにより、設置面Ｐとスクリーン本体２との間には間隙Ｄが形成される。 In the present embodiment, as shown in FIG. 2, the sticking surface 3 p sticking to the installation surface P in the sticking portion 3 is formed to protrude rearward from the screen main body 2. Thereby, a gap D is formed between the installation surface P and the screen main body 2.
　上記の如く、貼着部３の貼着面３ｐがスクリーン本体２よりも後方に突出するため、スクリーン装置１の設置状態では設置面Ｐとスクリーン本体２との間に間隙Ｄが形成される。このため、例えば設置面Ｐの表面上に小さな突部が存在する場合であっても、突部にスクリーン本体２が干渉せず、フラットで綺麗なスクリーン面を形成することができる。また、設置状態からスクリーン装置１を取り外す際、このスクリーン本体２と設置面Ｐとの間の間隙Ｄに手を挿入することができるため、取外し操作を容易に行なうことができる。さらに、スクリーン本体２が設置面Ｐから前方に突出していることで、スクリーン面に映し出された映像が、壁面とは区別された立体的なスクリーン面となり、映像が見やすくなる。 As described above, since the sticking surface 3p of the sticking portion 3 projects rearward from the screen main body 2, a gap D is formed between the setting surface P and the screen main body 2 when the screen device 1 is installed. Therefore, for example, even when a small protrusion exists on the surface of the installation surface P, the screen main body 2 does not interfere with the protrusion, and a flat and clean screen surface can be formed. Further, when removing the screen device 1 from the installation state, a hand can be inserted into the gap D between the screen main body 2 and the installation surface P, so that the removal operation can be easily performed. Furthermore, since the screen main body 2 protrudes forward from the installation surface P, the image projected on the screen surface becomes a three-dimensional screen surface distinguished from the wall surface, so that the image can be easily viewed.
　本実施形態に係るスクリーン装置１においては図３に示す如く、スクリーン本体２における四個の貼着部３の間隙部分（スクリーン面の四辺にあたる部分）には、スクリーン本体２の収縮時（スクリーン本体２を伸張させていない状態）において、スクリーン本体２の外側に向かって膨出する膨出部２ａが形成されている。即ち、図３に示す如く、スクリーン本体２は伸張していない状態においては略楕円形状となるように構成されている。 In the screen device 1 according to the present embodiment, as shown in FIG. 3, the space between the four sticking portions 3 in the screen main body 2 (portions corresponding to the four sides of the screen surface) is generated when the screen main body 2 is contracted (screen main body). 2 is not extended), a bulging portion 2a bulging toward the outside of the screen main body 2 is formed. That is, as shown in FIG. 3, the screen main body 2 is configured to have a substantially elliptical shape when it is not extended.
　スクリーン装置１においては上記の如く構成することにより、図４の第二の使用状態に示す如く、第一の使用状態における設置領域Ｍ１よりも設置領域Ｍ２を大きくして、貼着部３の間隔を広げ、貼着部３の近傍においてスクリーン本体２の変形が大きくなった場合に、貼着部３の間に膨出部２ａが位置する。このため、設置領域Ｍ２を大きくしてもスクリーン領域Ｓ２が小さくなることを防止できる。 By configuring the screen device 1 as described above, the installation area M2 is made larger than the installation area M1 in the first use state, as shown in the second use state of FIG. When the deformation of the screen main body 2 becomes large in the vicinity of the sticking portion 3, the bulging portion 2 a is located between the sticking portions 3. For this reason, it is possible to prevent the screen area S2 from becoming smaller even when the installation area M2 is made larger.
　さらに、スクリーン装置１においては、図５の第三の使用状態に示す如く設置領域Ｍ３をさらに大きくして貼着部３の間隔をより広げ、貼着部３の近傍においてスクリーン本体２の変形が最大限に大きくなった場合でも、貼着部３の間に膨出部２ａが位置する。このため、設置領域Ｍ３を最大限に大きくしてもスクリーン領域Ｓ３が小さくなることを抑制できる。 Further, in the screen device 1, as shown in the third use state of FIG. 5, the installation area M <b> 3 is further enlarged to further increase the interval between the sticking portions 3, and the deformation of the screen main body 2 near the sticking portion 3. Even when the size becomes maximum, the bulging portion 2 a is located between the sticking portions 3. For this reason, even if the installation area M3 is maximized, the screen area S3 can be prevented from being reduced.
　このように、本実施形態に係るスクリーン装置１によれば、設置領域を大きくしてスクリーン本体２を伸張させた場合でも、膨出部２ａを備えないスクリーン装置と比較して、設置領域に対するスクリーン領域の大きさを大きく確保することが可能となる。即ち、設置領域が限られた場合でも、スクリーン領域を大きく確保することができるのである。 As described above, according to the screen device 1 according to the present embodiment, even when the installation area is enlarged and the screen main body 2 is extended, the screen with respect to the installation area is compared with the screen device without the bulging portion 2a. It is possible to secure a large area size. That is, even when the installation area is limited, a large screen area can be secured.
　なお、本実施形態においては、膨出部２ａが大きく引き伸ばされるため、膨出部２ａの厚みを他の部分と比較して２５～３０％大きくなるように形成している。また、スクリーン本体２を形成する際にスクリーンシートを複数枚重ねることにより、スクリーン本体２が伸張された際に反射率が低下しないように構成している。 In the present embodiment, since the bulging portion 2a is greatly stretched, the bulging portion 2a is formed so as to be 25 to 30% thicker than other portions. Further, when the screen main body 2 is formed, a plurality of screen sheets are stacked so that the reflectivity does not decrease when the screen main body 2 is extended.
　なお、本実施形態に係るスクリーン装置１によれば、四個の貼着部３の間隙部分の全て（四箇所）に膨出部２ａを形成しているが、膨出部２ａを短辺のみ又は長辺のみに形成する構成としても差し支えない。また、四個の貼着部３の間隙部分の一箇所のみに膨出部２ａを形成しても良い。つまり、貼着部３の間隙部分のうち少なくとも一箇所に、スクリーン本体２が伸縮する方向に沿って膨出部２ａが形成されていれば、スクリーン本体２を伸張した際のスクリーン領域を大きくすることが可能となる。 In addition, according to the screen device 1 according to the present embodiment, the bulging portions 2a are formed in all (four) of the gaps between the four sticking portions 3, but the bulging portions 2a are formed only on the short side. Alternatively, it may be configured to be formed only on the long side. Further, the bulging portion 2a may be formed only at one portion of the gap between the four sticking portions 3. That is, if the bulging portion 2a is formed in at least one of the gap portions of the sticking portion 3 along the direction in which the screen main body 2 expands and contracts, the screen area when the screen main body 2 is extended is increased. It becomes possible.
　また、スクリーン装置１においては、貼着部３の貼着面３ｐがスクリーン本体２よりも後方に突出するため、スクリーン装置１の設置状態では設置面Ｐとスクリーン本体２との間に間隙Ｄが形成される。このため、図１及び図２における第一の使用状態に示す如く、設置領域Ｍ１が小さく貼着部３の間隔が狭い場合に、スクリーン本体２の膨出部２ａを、スクリーン本体２の後方に位置する間隙Ｄに垂れ下がらせることにより、スクリーン面を美しく保つことができる。 Further, in the screen device 1, since the sticking surface 3 p of the sticking portion 3 protrudes rearward from the screen main body 2, a gap D exists between the installation surface P and the screen main body 2 in the installation state of the screen device 1. It is formed. For this reason, as shown in the first use state in FIGS. 1 and 2, when the installation area M1 is small and the interval between the sticking parts 3 is small, the bulging part 2a of the screen main body 2 is moved backward of the screen main body 2. The screen surface can be kept beautiful by hanging down in the gap D located.
　また、上記の実施形態におけるスクリーン装置１において、貼着部３はスクリーン本体２の四箇所に設けられているが、貼着部の配置箇所及び数量はこのような構成に限られない。即ち、図６に示す別実施形態に係るスクリーン装置１１の如く、スクリーン本体２の短辺（及び／又は長辺）の中間部分にも各一個ずつ補助貼着部１３を更に設けることも可能である。これにより、スクリーン本体２を拡張した状態であっても、短辺において補助貼着部１３がスクリーン本体２を引張るため、スクリーン中央側へのスクリーン本体２の凹みを小さくすることできる。つまり、図６に示す如く設置領域Ｍ１１を大きくして、貼着部３の近傍においてスクリーン本体２の変形が最大限に大きくなった場合でも、補助貼着部１３によりスクリーン本体２を伸張させることができる。このため、設置領域Ｍ１１を最大限に大きくしてもスクリーン領域Ｓ１１が小さくなることをより抑制できるのである。 In addition, in the screen device 1 according to the above-described embodiment, the attaching portions 3 are provided at four positions of the screen main body 2, but the arrangement positions and the number of the attaching portions are not limited to such a configuration. That is, as in the screen device 11 according to another embodiment shown in FIG. 6, it is also possible to further provide one auxiliary sticking portion 13 at each intermediate portion of the short side (and / or the long side) of the screen main body 2. is there. Thereby, even when the screen main body 2 is expanded, the auxiliary sticking portion 13 pulls the screen main body 2 on the short side, so that the dent of the screen main body 2 toward the center of the screen can be reduced. That is, as shown in FIG. 6, the installation area M11 is enlarged, and even when the deformation of the screen main body 2 is maximized in the vicinity of the attaching section 3, the screen body 2 is extended by the auxiliary attaching section 13. Can be. For this reason, even if the installation area M11 is maximized, it is possible to further suppress the screen area S11 from becoming smaller.
　なお、上記のスクリーン装置１では、スクリーン本体やスクリーン面は長方形状に構成されているが、スクリーン本体の形状はこれに限定されるものではなく、正方形や三角形、六角形等の他の形状であってもよく、表示映像や用途に合わせてその形状を変形してもよい。また、伸張部材は磁力を有する貼着部３に限定されるものではなく、スクリーン本体を伸張させることのできる構成であれば良い。即ち、伸張部材は磁力によるものに限らず、吸盤、反復着脱可能な両面テープ、挟持部材、又はこれらの類するもの等、種々のものを適宜選択し、又は、併用することができる。 In the above-described screen device 1, the screen main body and the screen surface are formed in a rectangular shape, but the shape of the screen main body is not limited to this, and may be other shapes such as a square, a triangle, and a hexagon. The shape may be changed, and the shape may be changed in accordance with the display image or use. Further, the extension member is not limited to the sticking portion 3 having a magnetic force, and may be any configuration that can extend the screen body. That is, the extension member is not limited to a magnetic member, and various members such as a suction cup, a double-sided tape that can be repeatedly attached and detached, a holding member, and the like can be appropriately selected or used in combination.
　さらに、スクリーン装置１は、上述のような設置場所に限らず、貼着手段で設置可能な場所であればどのような場所でも取り付けることができ、例えば、円柱状の柱や球体等の曲面で構成されたものに巻き付けたり、階段等の凹凸形状に沿うように取り付けたりしてもよい。 Further, the screen device 1 is not limited to the above-described installation location, and can be attached to any location as long as it can be installed by the sticking means. For example, the screen device 1 may be a curved surface such as a column or a sphere. It may be wound around the structure or attached so as to follow the uneven shape of the stairs or the like.
　本発明に係る映写用伸縮スクリーン装置によれば、スクリーン本体の大きさを調節する際に、伸張部材を設置する領域に対してスクリーンとして使用する領域を大きく確保することができる。 According to the projection telescopic screen device of the present invention, when adjusting the size of the screen main body, it is possible to secure a larger area to be used as a screen than the area where the extension member is installed.
