以上の構成を有する折畳スクリーン1の使用方法について説明する。
まず、折畳スクリーン1を図4〜図6に示す収納状態から図1〜図3に示す使用状態とするには、使用者はまず脚部材5を揺動させて、上記開閉手段6を保持手段3の接地部材13から離脱させる。
次に、使用者は上記脚部材5の基端部を保持手段3のレール12に沿って上方位置から下方に移動させ、上記連結手段31のフランジ31bが上記乗越え突起14を乗越えた後に上記ストッパ15に当接して、脚部材5の基端部は保持手段3の略中央に位置決めされる。
さらに、使用者は保持手段3を保持して左右に離隔させ、これによりスクリーン2は巻取手段4におけるばねの付勢力に抗しながら回転軸21を回転させて展開されることとなる。
保持手段3が離隔して上記脚部材5の基端部が相互に離隔すると、上記開閉手段6における摺動面41a同士の摩擦力に抗してハウジング41が回転し、上記脚部材5がV字形に拡開する。
その際、使用者が開閉手段6を所要の開度に開くと、ハウジング41に形成した突起41b同士が係合して使用者にクリック感を与え、プロジェクタが照射する画面の縦横比に合わせてスクリーン2の幅を調整することが可能となっている。
そして、使用者は上記脚部材5の先端部をスクリーン2の後方離隔位置に揺動させ、上記保持手段3の下方の設置部材13と上記開閉手段6とを接地させることにより、折畳スクリーン1を3点支持により起立させる。
ここで、上記脚部材5の角度を適当に調整すれば、スクリーン2を略垂直に起立させることができ、その際上記脚部材5によって折畳スクリーン1の重心は後方に位置していることから、折畳スクリーン1が前方に倒れにくくなっている。
そして、使用者が保持手段3を離隔させた後も、上記巻取手段4によって上記保持手段3には接近する方向に付勢力が作用しているが、上記開閉手段6はこの付勢力に抗して脚部材5を拡開状態に保持し、スクリーン2は展開した状態を維持するようになっている。
The usage method of the folding screen 1 which has the above structure is demonstrated.
First, in order to change the folding screen 1 from the storage state shown in FIGS. 4 to 6 to the use state shown in FIGS. 1 to 3, the user first swings the leg member 5 to hold the opening / closing means 6. The ground member 13 of the means 3 is detached.
Next, the user moves the base end portion of the leg member 5 downward from the upper position along the rail 12 of the holding means 3, and after the flange 31 b of the connecting means 31 gets over the ride-over protrusion 14, the stopper 15, the base end portion of the leg member 5 is positioned substantially at the center of the holding means 3.
Further, the user holds the holding means 3 and separates it left and right, whereby the screen 2 is deployed by rotating the rotating shaft 21 against the urging force of the spring in the winding means 4.
When the holding means 3 is separated and the base ends of the leg members 5 are separated from each other, the housing 41 is rotated against the frictional force between the sliding surfaces 41a of the opening / closing means 6, and the leg member 5 is V Expand into a letter shape.
At that time, when the user opens the opening / closing means 6 to a required opening degree, the projections 41b formed on the housing 41 are engaged with each other to give the user a click feeling, in accordance with the aspect ratio of the screen irradiated by the projector. The width of the screen 2 can be adjusted.
Then, the user swings the tip of the leg member 5 to the rear separation position of the screen 2 and grounds the installation member 13 below the holding means 3 and the opening / closing means 6, thereby folding the folding screen 1. Is raised by supporting three points.
Here, if the angle of the leg member 5 is appropriately adjusted, the screen 2 can be erected substantially vertically, and the center of gravity of the folding screen 1 is positioned rearward by the leg member 5 at that time. The folding screen 1 is less likely to fall forward.
Even after the user separates the holding means 3, a biasing force is applied to the holding means 3 by the winding means 4, but the opening / closing means 6 resists this biasing force. Thus, the leg member 5 is held in the expanded state, and the screen 2 is maintained in the expanded state.

次に、上記折畳スクリーン1を使用状態から収納状態とするには、使用者はまず上記保持手段3を相互に接近させ、これにより上記巻取手段4がスクリーン2を回転軸21に巻取るとともに、上記脚部材5の基端部が相互に接近する。
上記保持手段3を相互に接近することで、上記開閉手段6は脚部材5が閉じるのを許容し、脚部材5は該開閉手段6によって閉鎖された状態に保持されるようになっている。
次に、使用者は脚部材5の基端部を上方に移動させるとともに、該脚部材5を揺動させて上記保持手段3に隣接した収納位置に移動させ、これにより上記開閉手段6が接地部材13の係合突起13aに係合することとなる。
Next, in order to change the folding screen 1 from the use state to the storage state, the user first brings the holding means 3 close to each other, whereby the winding means 4 winds the screen 2 around the rotating shaft 21. At the same time, the base ends of the leg members 5 approach each other.
By bringing the holding means 3 close to each other, the opening / closing means 6 allows the leg member 5 to be closed, and the leg member 5 is held in a closed state by the opening / closing means 6.

A method of using the folding screen 201 having the above configuration will be described.
First, in order to change the folding screen 201 from the storage state shown in FIGS. 12 to 14 to the use state shown in FIGS. 10 and 11, the user first moves the sliding member 213 of the holding means 203 from the upper position to the center position. Until the base end of the leg member 205 is moved to the center of the holding means 203.
Next, the user holds the holding member 211 located outside the holding means 203 and separates it left and right, whereby the screen 202 rotates the rotary shaft 221 against the urging force of the spring in the winding means 204. Will be deployed.
When the holding means 203 is separated, the base ends of the leg members 205 are separated from each other, and the opening / closing means 206 allows the leg members 205 to expand in a V shape while being deformed by the user's force. .
Then, the user swings the front end of the leg member 205 to the rear separation position of the screen 202, so that the opening / closing means 206 provided at the front end of the leg member 205 is positioned at the rear separation position of the screen 202. It becomes.
In this way, the connecting member 212 below the holding means 203 and the opening / closing means 206 can be grounded, and the folding screen 201 can be erected by three-point support.
Further, if the angle of the leg member 205 is appropriately adjusted, the screen 202 can be erected substantially vertically, and the center of gravity of the folding screen 201 is positioned rearward by the leg member 205 at that time. The folding screen 201 is less likely to fall forward.
Even after the user separates the holding means 203, a biasing force is applied to the holding means 203 by the winding means 204, but the opening / closing means 206 resists this biasing force. Thus, the leg member 205 is held in the expanded state, and the screen 202 is maintained in the expanded state.

次に、上記折畳スクリーン201を使用状態から収納状態とするには、使用者はまず上記保持手段203を相互に接近させ、これにより上記巻取手段204がスクリーン202を回転軸221に巻取るとともに、上記脚部材205の基端部が相互に接近する。

Next, in order to change the folding screen 201 from the use state to the storage state, the user first brings the holding means 203 close to each other, whereby the winding means 204 winds the screen 202 around the rotating shaft 221. At the same time, the base ends of the leg members 205 approach each other.
By bringing the holding means 203 close to each other, the opening / closing means 206 allows the leg member 205 to be closed, and the leg member 205 is configured as a rail 12 held in a state closed by the opening / closing means 206. .
Next, the user moves the sliding member 213 of the holding means 203 upward, and swings the leg member 205 to move it to a storage position adjacent to the holding member 211 of the holding means 203.
Then, the user moves the sliding member 213 upward to position the opening / closing means 206 provided at the tip of the leg member 205 above the lower connecting member 212 in the holding means 203.

なお、第1〜第3実施例における巻取手段4、104、204として、上記保持手段3、103、203の少なくともいずれか一方に回転軸を設け、さらにスクリーンが弾性を有して自ら上記回転軸に巻きつくような性質を有するものを使用することができる。
このような性質を持つフィルムは特許第2623105号の公報に記載されているように公知であるが、このようなスクリーンを用いることで、上記第1〜第3実施例における巻取手段のばねを省略することができ、折畳スクリーンをより軽量化、簡素化することが可能となる。
また上記巻取手段として、スクリーンが使用状態まで展開されると上記回転軸に係合し、スクリーンが巻き取られるのを阻止するストッパを設けた構成としてもよい。
この場合、使用状態において上記開閉手段には脚部材を閉鎖させる方向に付勢力が働かないため、上記開閉手段を第1〜第3実施例のような上記付勢力に抗して脚部材を拡開した状態に保持する構成としなくてもよい。
In addition, as the winding means 4, 104, 204 in the first to third embodiments, a rotating shaft is provided on at least one of the holding means 3, 103, 203, and the screen has elasticity so that it can rotate itself. Those having the property of winding around a shaft can be used.
A film having such properties is known as described in Japanese Patent No. 2623105. By using such a screen, the spring of the winding means in the first to third embodiments can be used. This can be omitted, and the folding screen can be made lighter and simplified.
Further, the winding means may be provided with a stopper that engages with the rotating shaft when the screen is expanded to the use state and prevents the screen from being wound.
In this case, since the urging force does not act on the opening / closing means in the direction of closing the leg member in use, the leg member is expanded against the urging force as in the first to third embodiments. It is not necessary to make it the structure hold | maintained in the open state.
