しかしながら、上記遮蔽装置は、開扉部分にスクリーンを張設するにあたり、ドアの内側に額縁があることを前提としていたり、スクリーンと同一の高さとなる大型の巻取軸を一対取り付ける必要があったりと、スクリーンの張設が容易ではない場合がある。すなわち、設置場所の制限や設置作業の点から、遮蔽装置の取り付けが必ずしも容易ではないという課題がある。 However, the above-mentioned shielding device assumes that there is a picture frame inside the door when the screen is stretched over the open door part, and it is necessary to attach a pair of large winding shafts that are the same height as the screen. And sometimes it is not easy to stretch the screen. That is, there is a problem that it is not necessarily easy to install the shielding device due to restrictions on the installation location and installation work.

本発明は、このような課題に鑑みてなされたものであり、ドアの一部を開扉した状態において、通風と目隠しとの両立が可能であり、かつ、取り付けが容易な遮蔽装置を提供することを目的とする。 SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and provides a shielding device that can be both ventilated and blinded when the door is partially open, and that is easy to install. for the purpose.

As shown in FIGS. 1 to 3 and 6 to 8, the shielding device 1 includes an upper holder 5 attached to the upper portion of the door 4 and an upper portion rotatably supported by the upper holder 5 at one end. It comprises a support member 6 , a plurality of strip-shaped louvers 7 suspended from the upper support member 6 and serving as shielding materials, and a lower support member 8 supporting the lower ends of the louvers 7 .

上部ホルダー５は、ドア４の上端部に取り付けられる枠体９と、枠体９に設けられるガイドレール１０とを有する。枠体９は、下方に開口した略コ字形状の板材である。ガイドレール１０は、Ｃ形チャネル状である。具体的には、ガイドレール１０は、縦断面略四角形の中空状で、下壁に長手方向に沿って案内溝１１が形成されている。案内溝１１は、ガイドレール１０の内外を連通可能に、下壁に貫通して形成されている。ガイドレール１０は、枠体９の下端部から、側方の外側に延出して設けられている。 The upper holder 5 has a frame 9 attached to the upper end of the door 4 and guide rails 10 provided on the frame 9 . The frame 9 is a substantially U-shaped plate material that opens downward. The guide rail 10 is C-channel shaped. Specifically, the guide rail 10 has a hollow shape with a substantially square vertical cross section, and a guide groove 11 is formed in the lower wall along the longitudinal direction. The guide groove 11 is formed through the lower wall so that the inside and outside of the guide rail 10 can communicate with each other. The guide rail 10 is provided so as to extend laterally outward from the lower end of the frame 9 .

上部ホルダー５は、枠体９がドア４の上端部に上方から嵌合することで、ドア４に着脱可能に取り付けられる。上部ホルダー５は、前述した構成であるので、ドア４に取り付けられた際、ガイドレール１０がドア４から外方に延出している。また、ガイドレール１０の長手方向は、ドア４の幅方向に沿っている。 The upper holder 5 is detachably attached to the door 4 by fitting the frame 9 to the upper end of the door 4 from above. Since the upper holder 5 has the structure described above, the guide rail 10 extends outward from the door 4 when the upper holder 5 is attached to the door 4 . Moreover, the longitudinal direction of the guide rail 10 is along the width direction of the door 4 .

上部支持部材６は、長手方向に延びる中空の直方体形状の部材である。上部支持部材６には、ランナー１２が設けられる。ランナー１２は、上下に離隔した板材１３，１４と、板材１３，１４を接続する接続部１５とを有する。上下の板材１３，１４は、円板状であり、対面して配置されている。接続部１５は、上下方向に沿う棒状で、上下の板材１３，１４の中心部同士を接続している。図３に示すように、ランナー１２は、下側の板材１４が上部支持部材６の一方の端部の内部に配置される。この際、ランナー１２の接続部１５は、上部支持部材６から上方に突出しており上側の板材１３が上部支持部材６の上面の上方に配置される。このようにしてランナー１２が取り付けられた上部支持部材６は、上部ホルダー５に取り付けられる。
上部支持部材６の他方の端部には、後述するドア枠２に設けられた吸着部材２６の凸部２８がはめ込まれる凹部３１が内方へ凹んで形成されている。 The upper support member 6 is a hollow rectangular parallelepiped member extending in the longitudinal direction. A runner 12 is provided on the upper support member 6 . The runner 12 has vertically separated plate members 13 and 14 and a connecting portion 15 that connects the plate members 13 and 14 . The upper and lower plate members 13 and 14 are disk-shaped and arranged facing each other. The connecting portion 15 has a rod shape along the vertical direction, and connects the center portions of the upper and lower plate members 13 and 14 to each other. As shown in FIG. 3, the runner 12 has a lower plate member 14 disposed inside one end of the upper support member 6 . At this time, the connection portion 15 of the runner 12 protrudes upward from the upper support member 6 , and the upper plate member 13 is arranged above the upper surface of the upper support member 6 . The upper support member 6 to which the runners 12 are attached in this manner is attached to the upper holder 5 .
The other end of the upper support member 6 is formed with an inwardly recessed recess 31 into which a protrusion 28 of an adsorption member 26 provided on the door frame 2 (to be described later) is fitted.

上部支持部材６は、ランナー１２を介して、上部ホルダー５のガイドレール１０に設けられる。具体的には、上部支持部材６は、ランナー１２の上側の板材１３がガイドレール１０内に収容されることで、ガイドレール１０に取り付けられる。この際、ランナー１２の接続部１５は、ガイドレール１０の案内溝１１に配置される。このような構成により、上部支持部材６の一方の端部は、上部ホルダー５に回動自在に支持される。また、上部支持部材６の一方の端部は、ガイドレール１０に回動自在に支持されるとともに、ガイドレール１０にその長手方向に沿って移動可能に支持される。すなわち、上部支持部材６の一方の端部は、ドア４の上端部近傍に回動自在に支持される。 The upper support member 6 is provided on guide rails 10 of the upper holder 5 via runners 12 . Specifically, the upper support member 6 is attached to the guide rail 10 by accommodating the plate member 13 above the runner 12 in the guide rail 10 . At this time, the connecting portion 15 of the runner 12 is arranged in the guide groove 11 of the guide rail 10 . With such a configuration, one end of the upper support member 6 is rotatably supported by the upper holder 5 . One end of the upper support member 6 is rotatably supported by the guide rail 10 and is also movably supported by the guide rail 10 along its longitudinal direction. That is, one end of the upper support member 6 is rotatably supported near the upper end of the door 4 .

上部支持部材６には、複数のルーバー７が設けられる。複数のルーバー７は、上部支持部材６の長手方向に沿って並んでいる。図２に示すように、ルーバー７は、上部フック１６を介して、上部支持部材６に吊り下げられる。上部フック１６は、鉛直軸まわりに回転可能に、上部支持部材６に設けられる。この上部フック１６に、ルーバー７が吊り下げられる。具体的には、ルーバー７の上端部を折り返して形成された上部袋状部１７に、上部フック１６の一部が収容されることで、上部フック１６にルーバー７が吊り下げられる。上部フック１６にルーバー７が吊り下げられることで、ルーバー７は、上部支持部材６に対して鉛直軸まわりに回転可能とされる。すなわち、ルーバー７は、水平方向に回転可能に、上部支持部材６に設けられる。 A plurality of louvers 7 are provided on the upper support member 6 . A plurality of louvers 7 are arranged along the longitudinal direction of the upper support member 6 . As shown in FIG. 2 , the louvers 7 are suspended from the upper support member 6 via upper hooks 16 . An upper hook 16 is provided on the upper support member 6 so as to be rotatable about a vertical axis. A louver 7 is suspended from the upper hook 16 . Specifically, the louver 7 is suspended from the upper hook 16 by partially accommodating the upper hook 16 in the upper bag-like portion 17 formed by folding the upper end portion of the louver 7 . The louvers 7 are suspended from the upper hooks 16 so that the louvers 7 can rotate about the vertical axis with respect to the upper support member 6 . That is, the louver 7 is provided on the upper support member 6 so as to be rotatable in the horizontal direction.

下部支持部材８は、例えばラバー等からなり、長手方向に延びる部材である。図６及び図７に示すように、下部支持部材８には、ルーバー７の下端部が支持される。そのため、下部支持部材８の上面には、マグネットからなる吸着部材１８が設けられている。また、ルーバー７の下端部には、下部フック１９が設けられる。下部フック１９は、上下方向に沿って配置される本体部２０と、本体部２０の下端部に設けられる連結部２１と、下部支持部材８に設けられる吸着部材１８に着脱可能に吸着される被吸着部２２とを有する。被吸着部２２は、マグネットからなり、連結部２１の下端部に設けられる。被吸着部２２は、連結部２１に対して回転可能である。言い換えれば、連結部２１は、被吸着部２２に対して回転可能である。 The lower support member 8 is a member made of rubber or the like and extending in the longitudinal direction. As shown in FIGS. 6 and 7 , the lower support member 8 supports the lower end of the louver 7 . Therefore, an attraction member 18 made of a magnet is provided on the upper surface of the lower support member 8 . A lower hook 19 is provided at the lower end of the louver 7 . The lower hook 19 includes a body portion 20 arranged along the vertical direction, a connection portion 21 provided at the lower end portion of the body portion 20, and a suction member 18 provided on the lower support member 8. and a suction unit 22 . The attracted portion 22 is made of a magnet and provided at the lower end portion of the connecting portion 21 . The sucked portion 22 is rotatable with respect to the connecting portion 21 . In other words, the connecting portion 21 is rotatable with respect to the sucked portion 22 .

下部フック１９は、一部がルーバー７の下端部を折り返して形成された下部袋状部２３に収容されることで、ルーバー７の下端部に取り付けられる。この際、本体部２０、連結部２１及び被吸着部２２は、ルーバー７から下方に突出している。図６及び図７に示すように、下部支持部材８に設けられた吸着部材１８に下部フック１９の被吸着部２２を吸着させることで、ルーバー７は、下部フック１９を介して、下部支持部材８に支持される。また、下部フック１９が被吸着部２２に対して回転可能である連結部２１を有しているので、ルーバー７は、下部支持部材８に対して鉛直軸まわりに回転可能とされる。すなわち、ルーバー７は、水平方向に回転可能に、下部支持部材８に設けられる。従って、下部支持部材８は、ルーバー７の下端部を着脱自在及び回転可能に支持することができる。 The lower hook 19 is attached to the lower end portion of the louver 7 by being accommodated in a lower bag-like portion 23 formed by folding the lower end portion of the louver 7 . At this time, the body portion 20 , the connecting portion 21 and the sucked portion 22 protrude downward from the louver 7 . As shown in FIGS. 6 and 7 , the louvers 7 are attached to the lower support member 8 via the lower hooks 19 by causing the suction members 18 provided on the lower support member 8 to adsorb the attracted portions 22 of the lower hooks 19 . 8 supported. Further, since the lower hook 19 has the connecting portion 21 rotatable with respect to the sucked portion 22 , the louver 7 is rotatable about the vertical axis with respect to the lower support member 8 . That is, the louver 7 is provided on the lower support member 8 so as to be rotatable in the horizontal direction. Therefore, the lower support member 8 can detachably and rotatably support the lower end of the louver 7 .

前述したように、ルーバー７の上端部は、上部支持部材６に対して鉛直軸まわりに回転可能である。また、前述したように、ルーバー７の下端部は、下部支持部材８に対して鉛直軸まわりに回転可能である。従って、ルーバー７は、上部支持部材６及び下部支持部材８に支持された状態において、縦軸まわりに回転して開閉可能とされる。 As described above, the upper end of the louver 7 is rotatable relative to the upper support member 6 around the vertical axis. Also, as described above, the lower end of the louver 7 is rotatable about the vertical axis with respect to the lower support member 8 . Therefore, the louver 7 can be opened and closed by rotating around the vertical axis while being supported by the upper support member 6 and the lower support member 8 .

図６及び図７に示すように、下部支持部材８の一方の端部には、ドア４の下端部に設けられた吸着材２４に吸着される被吸着材２５が設けられる。ここで、吸着材２４及び被吸着材２５は、マグネットから構成されている。従って、下部支持部材８の一方の端部は、ドア４の下端部近傍に設けられた吸着材２４に着脱可能に吸着させることができる。 As shown in FIGS. 6 and 7 , one end of the lower support member 8 is provided with an adsorbed material 25 that is adsorbed by an adsorbent 24 provided at the lower end of the door 4 . Here, the adsorbing material 24 and the adsorbed material 25 are composed of magnets. Accordingly, one end of the lower support member 8 can be detachably attracted to the adsorbent 24 provided near the lower end of the door 4 .

次に、第１実施形態による遮蔽装置１の動作を説明しながら、遮蔽装置１の作用及び効果を説明する。 Next, while explaining the operation of the shielding device 1 according to the first embodiment, the action and effect of the shielding device 1 will be explained.

図８（ａ）に示すように、ドア４が一部開扉した状態において、遮蔽装置１は、上部支持部材６の他方の端部がドア枠２に連結された第１の状態とすることで、ドア４とドア枠２との間の開扉空間をルーバー７によって通風可能に閉塞できる。従って、遮蔽装置１は、第１の状態において、開扉空間の目隠し及び通風を行うことができる。 As shown in FIG. 8A, when the door 4 is partially open, the shielding device 1 is in a first state in which the other end of the upper support member 6 is connected to the door frame 2. The open door space between the door 4 and the door frame 2 can be closed by the louver 7 so as to allow ventilation. Therefore, the shielding device 1 can blind and ventilate the open door space in the first state.

図４及び図５に示すように、上部支持部材６の他方の端部をドア枠２に連結するために、ドア枠２には、マグネットからなる吸着部材２６が設けられる。吸着部材２６は、略四角形状の平板部２７と、平板部２７の一方の板面から突出する円錐状の凸部２８とを有する。吸着部材２６は、台座２９を介して、ドア枠２に設けられる。台座２９は、略矩形ブロック状であり、基端部がドア枠２の上端部近傍に設けられる。台座２９の先端面３０は、ドア枠２の内方へ向くように傾斜している。台座２９の先端面３０に平板部２７の他方の板面を固定することで、吸着部材２６は、ドア枠２に設けられる。一方、上部支持部材６の他方の端部には、吸着部材２６の凸部２８がはめ込まれる凹部３１が内方へ凹んで形成されている。凹部３１は少なくとも一部が磁性体で構成される。 As shown in FIGS. 4 and 5, the door frame 2 is provided with an attracting member 26 made of a magnet in order to connect the other end of the upper support member 6 to the door frame 2 . The adsorption member 26 has a substantially rectangular flat plate portion 27 and a conical protrusion 28 protruding from one plate surface of the flat plate portion 27 . The adsorption member 26 is provided on the door frame 2 via a pedestal 29 . The pedestal 29 has a substantially rectangular block shape, and its base end is provided in the vicinity of the upper end of the door frame 2 . A front end surface 30 of the base 29 is inclined toward the inside of the door frame 2 . The adsorption member 26 is provided on the door frame 2 by fixing the other plate surface of the flat plate portion 27 to the tip surface 30 of the pedestal 29 . On the other hand, the other end of the upper support member 6 is formed with an inwardly recessed recess 31 into which the protrusion 28 of the adsorption member 26 is fitted. At least a portion of the recess 31 is made of a magnetic material.

このような構成であるので、上部支持部材６の凹部３１に吸着部材２６の凸部２８をはめ込むとともに、上部支持部材６の他方の端部を吸着部材２６に吸着させることで、上部支持部材６の他方の端部は、ドア枠２に連結される。これにより、遮蔽装置１は、前述した第１の状態に固定される。また、吸着部材２６がマグネットから構成されているので、上部支持部材６は、ドア枠２に設けられた吸着部材２６に対して着脱可能に吸着される。 With such a configuration, the protrusion 28 of the adsorption member 26 is fitted into the recess 31 of the upper support member 6, and the other end of the upper support member 6 is adsorbed to the adsorption member 26, whereby the upper support member 6 can be moved. The other end of is connected to the door frame 2 . Thereby, the shielding device 1 is fixed in the first state described above. Further, since the attraction member 26 is composed of a magnet, the upper support member 6 is detachably attracted to the attraction member 26 provided on the door frame 2 .

第１の状態では、上部支持部材６の一方の端部は、ガイドレール１０のドアノブ３２側の端部である一端部側に位置しており、上部支持部材６の他方の端部は、ドア枠２に連結されている。従って、上部支持部材６は、ドア４とドア枠２との間を斜めに架け渡すように配置される。この状態では、ルーバー７の下端部は、前述したように下部支持部材８に支持されている。また、下部支持部材８の一方の端部が吸着材２４に吸着されることにより、下部支持部材８は、ドア４の下端部近傍に連結されている。 In the first state, one end of the upper support member 6 is located on the one end side of the guide rail 10 on the doorknob 32 side, and the other end of the upper support member 6 is positioned on the door handle 32 side. It is connected to the frame 2. Therefore, the upper support member 6 is arranged so as to bridge between the door 4 and the door frame 2 obliquely. In this state, the lower end of the louver 7 is supported by the lower support member 8 as described above. One end of the lower support member 8 is attached to the adsorbent 24 so that the lower support member 8 is connected to the vicinity of the lower end of the door 4 .

第１実施形態では、ルーバー７は、上部支持部材６及び下部支持部材８に支持された状態において所定の角度で開くように、図示しない付勢部材により付勢されている。すなわち、ルーバー７は、上部支持部材６の長手方向に沿った状態から傾斜している。ルーバー７における上部支持部材６の長手方向に沿った状態からの傾斜角度は、例えば、１５°よりも大きくて４５°よりも小さい。ルーバー７が所定の角度で開いていることにより、隣接するルーバー７，７同士の間には、隙間が形成される。従って、遮蔽装置１は、目隠し及び通風が可能である。 In the first embodiment, the louver 7 is biased by a biasing member (not shown) so as to open at a predetermined angle while being supported by the upper support member 6 and the lower support member 8 . That is, the louvers 7 are inclined from the longitudinal direction of the upper support member 6 . The angle of inclination of the louver 7 from the longitudinal direction of the upper support member 6 is, for example, greater than 15° and less than 45°. A gap is formed between adjacent louvers 7, 7 by opening the louvers 7 at a predetermined angle. Therefore, the shielding device 1 can be blinded and ventilated.

図８（ａ）に示すように、上部支持部材６がドア４とドア枠２との間に架け渡され、ルーバー７が所定の角度に開いていることで、第１の状態では、開扉空間をルーバー７によって通風可能に閉塞できる。この第１の状態から、図８（ｂ）に示すように、上部支持部材６の他方の端部のドア枠２との連結を解除する。そして、上部支持部材６の他方の端部を反時計回りに回転させるとともに、上部支持部材６の一方の端部をガイドレール１０の長手方向一端部から長手方向他端部に移動させる。これにより、ルーバー７とドアノブ３２とが接触するのを防止できる。なお、上部支持部材６を操作する前には、下部支持部材８とドア４との連結を解除しておく。 As shown in FIG. 8(a), the upper support member 6 is bridged between the door 4 and the door frame 2, and the louver 7 is opened at a predetermined angle, so that the door is open in the first state. The space can be closed by the louver 7 so as to allow ventilation. From this first state, the other end of the upper support member 6 is disconnected from the door frame 2 as shown in FIG. 8(b). Then, the other end of the upper support member 6 is rotated counterclockwise, and the one end of the upper support member 6 is moved from one end in the longitudinal direction of the guide rail 10 to the other end in the longitudinal direction. Thereby, contact between the louver 7 and the doorknob 32 can be prevented. Before operating the upper support member 6, the connection between the lower support member 8 and the door 4 is released.

図８（ｃ）に示すように、上部支持部材６の一方の端部がガイドレール１０の長手方向他端部に到達するとともに、上部支持部材６の他方の端部がドア４側に到達することで、上部支持部材６の他方の端部がドア４側に収容された第２の状態となる。この第２の状態では、開扉空間は開放されている。この際、上部ホルダー５に支持される上部支持部材６の一方の端部を支点に、上部支持部材６が回動する。また、上部支持部材６は、ガイドレール１０の長手方向に沿って移動しながら回動する。以上のように、ドア４が一部開扉した状態において、上部支持部材６が第１の状態に切り替えられると、ドア４とドア枠２との間の開扉空間がルーバー７によって通風可能に閉塞され、上部支持部材６が第２の状態に切り替えられると、開扉空間が開放される。 As shown in FIG. 8(c), one end of the upper support member 6 reaches the other longitudinal end of the guide rail 10, and the other end of the upper support member 6 reaches the door 4 side. Thus, the second state in which the other end of the upper support member 6 is accommodated on the door 4 side is achieved. In this second state, the open door space is open. At this time, the upper support member 6 rotates around one end of the upper support member 6 supported by the upper holder 5 as a fulcrum. Also, the upper support member 6 rotates while moving along the longitudinal direction of the guide rail 10 . As described above, when the upper support member 6 is switched to the first state while the door 4 is partially open, the open door space between the door 4 and the door frame 2 can be ventilated by the louver 7. When closed and the upper support member 6 is switched to the second state, the open door space is opened.

第１実施形態による遮蔽装置１の場合、ドア４とドア枠２との間の開扉空間を通風可能に閉塞したり、開放したりすることができる。また、第１の状態と第２の状態との切替が可能な上部支持部材６に吊り下げるだけでルーバー７を取り付けることができるため、設置場所の制限もなく取り付けが容易な遮蔽装置１を提供できる。 In the case of the shielding device 1 according to the first embodiment, the open door space between the door 4 and the door frame 2 can be ventilably closed or opened. In addition, since the louver 7 can be attached simply by hanging it on the upper support member 6 that can be switched between the first state and the second state, the shielding device 1 can be easily installed without restrictions on the installation location. can.

また、第１実施形態による遮蔽装置１の場合、上部ホルダー５をドア４の上端部に嵌合させるだけで、容易に上部支持部材６及びルーバー７を取り付けることができる。また、第１実施形態による遮蔽装置１の場合、上部支持部材６がガイドレール１０の長手方向に沿って移動できるため、例えば、ルーバー７とドアノブ３２との干渉を避けながら、第１の状態から第２の状態に切り替えることができる。また、第１実施形態による遮蔽装置１の場合、ルーバー７が所定の角度で開くように、付勢部材により付勢されている。従って、通風と目隠しとの両立が可能な角度となるように、ルーバー７の開閉角度を維持することができる。 Further, in the case of the shielding device 1 according to the first embodiment, the upper support member 6 and the louvers 7 can be easily attached simply by fitting the upper holder 5 to the upper end portion of the door 4 . In the case of the shielding device 1 according to the first embodiment, since the upper support member 6 can move along the longitudinal direction of the guide rail 10, for example, while avoiding interference between the louver 7 and the doorknob 32, the shielding device 1 can be moved from the first state. It can switch to a second state. Further, in the case of the shielding device 1 according to the first embodiment, the louver 7 is urged by the urging member so as to open at a predetermined angle. Therefore, the opening/closing angle of the louver 7 can be maintained so as to achieve an angle that allows both ventilation and blinding.

また、第１実施形態による遮蔽装置１の場合、上部支持部材６が吸着部材２６に吸着されることにより、第１の状態で固定される。従って、上部支持部材６を容易にドア枠２に連結することができるとともに、前記連結を容易に解除することができる。これにより、第１の状態と第２の状態との切替が容易となる。 Further, in the case of the shielding device 1 according to the first embodiment, the upper support member 6 is adsorbed by the adsorption member 26, thereby being fixed in the first state. Therefore, the upper support member 6 can be easily connected to the door frame 2, and the connection can be easily released. This facilitates switching between the first state and the second state.

また、第１実施形態による遮蔽装置１の場合、ルーバー７の下端部が下部支持部材８に支持される。従って、ルーバー７の下端部がバタつくことを防止できる。
さらに、第１実施形態による遮蔽装置１の場合、下部支持部材８が吸着材２４に吸着されることにより、下部支持部材８がドア４の下端部近傍に連結される。従って、下部支持部材８に足が当たってしまった場合等に、下部支持部材８がドア４の下端部から容易に外れるため、遮蔽装置１の損傷を防ぐことができるとともに、安全面においても優位である。なお、上述した通り、下部支持部材８をラバー等からなる部材とした場合には、下部支持部材８の吸着材２４への着脱操作を足で行うようにしてもよい。これにより、第１の状態と第２の状態との切替がより容易となる。 Moreover, in the case of the shielding device 1 according to the first embodiment, the lower end of the louver 7 is supported by the lower support member 8 . Therefore, it is possible to prevent the lower end of the louver 7 from flapping.
Furthermore, in the case of the shielding device 1 according to the first embodiment, the lower support member 8 is connected to the vicinity of the lower end of the door 4 by being adsorbed by the adsorbent 24 . Therefore, if the lower support member 8 is hit by a foot or the like, the lower support member 8 can be easily removed from the lower end of the door 4, so that the shielding device 1 can be prevented from being damaged, and safety is also superior. is. As described above, when the lower support member 8 is made of rubber or the like, the attachment and detachment operation of the lower support member 8 to and from the adsorbent 24 may be performed by foot. This makes it easier to switch between the first state and the second state.

（第２実施形態）
次に、第２実施形態による遮蔽装置１Ａの構成を説明する。なお、第１実施形態で付した符号と同じ符号を有する構成品は、その作用を同じにするので以下、説明を省略することがある。第２実施形態による遮蔽装置１Ａは、ルーバー７を支持する部材の構成が第１実施形態と異なる。図９に示すように、第２実施形態による遮蔽装置１Ａは、一方の端部がドア４の上端部近傍に回動自在に支持される支持部材３３と、支持部材３３に取り付けられた遮蔽材となるルーバー７とを備える。 (Second embodiment)
Next, the configuration of the shielding device 1A according to the second embodiment will be described. Components having the same reference numerals as those in the first embodiment have the same functions, and hence descriptions thereof may be omitted. A shielding device 1A according to the second embodiment differs from that of the first embodiment in the configuration of members that support the louvers 7. FIG. As shown in FIG. 9, the shielding device 1A according to the second embodiment includes a supporting member 33, one end of which is rotatably supported near the upper end of the door 4, and a shielding member attached to the supporting member 33. A louver 7 is provided.

支持部材３３は、上下の枠を含む枠体で形成されている。具体的には、支持部材３３は、略コ字形状で、上下方向に沿う中央枠３４と、中央枠３４の上端部に設けられる上枠３５と、中央枠３４の下端部に設けられる下枠３６とを有する。上枠３５には、ランナー１２が設けられる。この際、ランナー１２の接続部１５は、上枠３５から上方に突出している。このようにしてランナー１２が取り付けられた支持部材３３は、第１実施形態の上部支持部材６と同様にして、第１実施形態の上部ホルダー５に設けられる。 The support member 33 is formed of a frame including upper and lower frames. Specifically, the support member 33 has a substantially U-shape, and includes a central frame 34 extending in the vertical direction, an upper frame 35 provided at the upper end of the central frame 34, and a lower frame provided at the lower end of the central frame 34. 36. A runner 12 is provided on the upper frame 35 . At this time, the connecting portion 15 of the runner 12 protrudes upward from the upper frame 35 . The support member 33 to which the runners 12 are attached in this manner is provided in the upper holder 5 of the first embodiment in the same manner as the upper support member 6 of the first embodiment.

支持部材３３の一方の端部には、ドア４に設けられた吸着材３７に吸着される被吸着材３８が設けられる。例えば、吸着材３７は、ドア４の下端部に設けられ、被吸着材３８は、支持部材３３の中央枠３４の下端部に設けられる。ここで、吸着材３７及び被吸着材３８は、マグネットから構成されている。従って、支持部材３３の一方の端部は、ドア４の下端部近傍に設けられた吸着材３７に着脱可能に吸着させることができる。 One end of the support member 33 is provided with an adsorbed material 38 that is adsorbed by an adsorbent 37 provided on the door 4 . For example, the adsorbent 37 is provided at the lower end of the door 4 and the adsorbed material 38 is provided at the lower end of the central frame 34 of the support member 33 . Here, the adsorbing material 37 and the adsorbed material 38 are composed of magnets. Therefore, one end of the support member 33 can be detachably adsorbed to the adsorbent 37 provided near the lower end of the door 4 .

このような構成であるので、支持部材３３は、一方の端部がドア４側に連結された状態で他方の端部がドア４側から転回された第１の状態と、他方の端部がドア４側に収容された第２の状態とに切替可能である。この切替は、第１実施形態の上部支持部材６と同様に、支持部材３３を動作させることでなされる。この際、支持部材３３である枠体の一部がドア４に吸着されることで第１の状態で固定され、吸着が解除されるとドア４側に支持部材３３が収容されて第２の状態に切り替わる。 With such a configuration, the support member 33 has a first state in which one end is connected to the door 4 side and the other end is turned from the door 4 side, and a first state in which the other end is turned from the door 4 side. It can be switched to the second state in which it is accommodated on the door 4 side. This switching is performed by operating the support member 33 in the same manner as the upper support member 6 of the first embodiment. At this time, a part of the frame body, which is the support member 33, is attracted to the door 4 to be fixed in the first state. switch to state.

ルーバー７は、上枠３５と下枠３６との間を架け渡すようにして、支持部材３３に設けられる。ルーバー７の上端部は、第１実施形態の上部支持部材６に取り付ける場合と同様にして、上枠３５に取り付けられる。ルーバー７の下端部は、下部フック３９を介して、下枠３６に支持される。具体的には、ルーバー７の下端部の下部袋状部２３に下部フック３９の一部が収容されるとともに、下部フック３９が鉛直軸まわりに回転可能に下枠３６に設けられる。これにより、ルーバー７は、支持部材３３に対して鉛直軸まわりに回転可能とされる。すなわち、ルーバー７は、水平方向に回転可能に、支持部材３３に設けられる。従って、ルーバー７は、上枠３５及び下枠３６に支持された状態において、縦軸まわりに回転して開閉可能とされる。なお、ルーバー７は、第１実施形態の場合と同様に、所定の角度で開くように、図示しない付勢部材により付勢されている。 The louver 7 is provided on the support member 33 so as to span between the upper frame 35 and the lower frame 36 . The upper end of the louver 7 is attached to the upper frame 35 in the same manner as the upper support member 6 of the first embodiment. A lower end portion of the louver 7 is supported by the lower frame 36 via a lower hook 39 . Specifically, a part of the lower hook 39 is accommodated in the lower bag-shaped portion 23 at the lower end of the louver 7, and the lower hook 39 is provided on the lower frame 36 so as to be rotatable around the vertical axis. Thereby, the louver 7 is rotatable about the vertical axis with respect to the support member 33 . That is, the louver 7 is provided on the support member 33 so as to be rotatable in the horizontal direction. Therefore, the louver 7 can be opened and closed by rotating about the vertical axis while being supported by the upper frame 35 and the lower frame 36 . The louver 7 is biased by a biasing member (not shown) so as to open at a predetermined angle, as in the case of the first embodiment.

第２実施形態においても支持部材３３を操作することで、第１実施形態と同様に、第１の状態と第２の状態とを切り替えることができる。具体的には、ドア４が一部開扉した状態において、支持部材３３が第１の状態に切り替えられると、ドア４とドア枠２との間の開扉空間がルーバー７によって通風可能に閉塞され、支持部材３３が第２の状態に切り替えられると、開扉空間が開放される。 Also in the second embodiment, by operating the support member 33, it is possible to switch between the first state and the second state in the same manner as in the first embodiment. Specifically, when the support member 33 is switched to the first state while the door 4 is partially open, the opening space between the door 4 and the door frame 2 is blocked by the louver 7 so as to allow ventilation. When the support member 33 is switched to the second state, the open door space is opened.

第２実施形態による遮蔽装置１Ａの場合、第１の状態において、支持部材３３の一方の端部がドア４に着脱可能に吸着されている。従って、第１の状態と第２の状態との切替にあたり、支持部材３３をドア枠２に連結させる必要がない。そのため、より簡易な構成とすることができる。また、第２実施形態による遮蔽装置１Ａの場合、第１実施形態のように上部支持部材６及び下部支持部材８を個別に着脱操作しなくてもよいため、利便性を向上させることができる。 In the shielding device 1A according to the second embodiment, one end of the support member 33 is detachably attached to the door 4 in the first state. Therefore, it is not necessary to connect the support member 33 to the door frame 2 when switching between the first state and the second state. Therefore, a simpler configuration can be achieved. Further, in the case of the shielding device 1A according to the second embodiment, unlike the first embodiment, the upper support member 6 and the lower support member 8 do not have to be individually attached and detached, so convenience can be improved.

（第３実施形態）
次に、第３実施形態による遮蔽装置１Ｂの構成を説明する。なお、第１実施形態及び第２実施形態で付した符号と同じ符号を有する構成品は、その作用を同じにするので以下、説明を省略することがある。第３実施形態による遮蔽装置１Ｂは、第２実施形態の構成に加えて、第１の状態から第２の状態に自動で切り替えられる構成である。そのため、図１０に示すように、第３実施形態による遮蔽装置１Ｂでは、付勢部材４０が設けられる。付勢部材４０は、例えばコイルバネである。 (Third Embodiment)
Next, the configuration of the shielding device 1B according to the third embodiment will be described. Components having the same reference numerals as those in the first embodiment and the second embodiment have the same functions, and hence the description thereof may be omitted. In addition to the configuration of the second embodiment, the shielding device 1B according to the third embodiment is configured to automatically switch from the first state to the second state. Therefore, as shown in FIG. 10, a biasing member 40 is provided in the shielding device 1B according to the third embodiment. The biasing member 40 is, for example, a coil spring.

コイルバネ４０は、一端部がランナー１２に固定され、他端部がガイドレール１０の長手方向他端部に固定されて、ガイドレール１０内に収容されている。これにより、図１０（ａ）に示すように、支持部材３３の一方の端部は、第１の状態において、ガイドレール１０の長手方向他端部側に付勢されている。この第１の状態から、図１０（ｂ）に示すように、支持部材３３とドア４との吸着を解除して支持部材３３を反時計まわりに回転させることで、支持部材３３の一方の端部は、コイルバネ４０によりガイドレール１０の長手方向他端部に自動で移動する。ここで、支持部材３３とドア４との吸着を解除して支持部材３３を反時計まわりに回転させる際には、支持部材３３をドア枠２側に若干移動させる。これにより、支持部材３３を反時計方向に回転させる際に、支持部材３３の一方の端部がドア４に接触して回転できなくなるのを防止できる。そして、図１０（ｃ）に示すように、支持部材３３の一方の端部がガイドレール１０の長手方向他端部に到達すると、支持部材３３は、他方の端部がドア４側に収容された第２の状態になる。 The coil spring 40 is accommodated in the guide rail 10 with one end fixed to the runner 12 and the other end fixed to the other longitudinal end of the guide rail 10 . Accordingly, as shown in FIG. 10A, one end of the support member 33 is biased toward the other end in the longitudinal direction of the guide rail 10 in the first state. From this first state, as shown in FIG. 10(b), the suction between the support member 33 and the door 4 is released and the support member 33 is rotated counterclockwise to move one end of the support member 33. is automatically moved to the other longitudinal end of the guide rail 10 by the coil spring 40 . Here, when releasing the adsorption between the support member 33 and the door 4 and rotating the support member 33 counterclockwise, the support member 33 is slightly moved toward the door frame 2 side. As a result, when rotating the support member 33 counterclockwise, it is possible to prevent one end of the support member 33 from coming into contact with the door 4 and becoming unable to rotate. Then, as shown in FIG. 10(c), when one end of the support member 33 reaches the other end in the longitudinal direction of the guide rail 10, the other end of the support member 33 is housed on the door 4 side. the second state.

このように第３実施形態では、支持部材３３である枠体の一部がドア４に吸着されることで第１の状態で固定され、吸着が解除されると自動でドア４側に支持部材３３が収容されて第２の状態に切り替わるように支持部材３３の一方の端部が付勢されている。従って、第３実施形態の遮蔽装置１Ｂの場合、支持部材３３とドア４との連結を解除すれば、支持部材３３が自動でドア４側に収容されるため、利便性を向上させることができる。 As described above, in the third embodiment, a portion of the frame, which is the support member 33, is attached to the door 4 and fixed in the first state. One end of support member 33 is biased so that 33 is retracted to switch to the second state. Therefore, in the case of the shielding device 1B of the third embodiment, when the support member 33 and the door 4 are disconnected, the support member 33 is automatically accommodated on the side of the door 4, thereby improving convenience. .

（第４実施形態）
次に、第４実施形態による遮蔽装置１Ｃの構成を説明する。なお、第１実施形態で付した符号と同じ符号を有する構成品は、その作用を同じにするので以下、説明を省略することがある。第４実施形態による遮蔽装置１Ｃは、上部支持部材６が設けられるガイドレールのドア４への取付構成が異なる。すなわち、第１実施形態による遮蔽装置１では、枠体９がドア４の上端部に嵌合されることでガイドレール１０がドア４に設けられたが、第４実施形態による遮蔽装置１Ｃでは、ガイドレール４１がマグネットからなる吸着部材４２によってドア４に着脱可能に取り付けられる。 (Fourth embodiment)
Next, the configuration of the shielding device 1C according to the fourth embodiment will be described. Components having the same reference numerals as those in the first embodiment have the same functions, and hence descriptions thereof may be omitted. 1 C of shielding apparatuses by 4th Embodiment differ in the attachment structure to the door 4 of the guide rail in which the upper support member 6 is provided. That is, in the shielding device 1 according to the first embodiment, the guide rail 10 is provided on the door 4 by fitting the frame 9 to the upper end portion of the door 4, but in the shielding device 1C according to the fourth embodiment, A guide rail 41 is detachably attached to the door 4 by an attraction member 42 made of a magnet.

第４実施形態では、ドア４の上端部に吸着部材４２が設けられる。この吸着部材４２に吸着される部分がガイドレール４１に形成されている。具体的には、ガイドレール４１は、Ｃ形チャネル状のガイドレール本体部４３と、吸着部材４２への吸着部４４とを有する。吸着部４４は、板状で、吸着部材４２に対向する面の少なくとも一部が磁性体によって構成され、ガイドレール本体部４３の幅方向の一端部に、板面がガイドレール本体部４３の長手方向に沿うようにして立設されている。 In the fourth embodiment, a suction member 42 is provided at the upper end portion of the door 4 . A portion of the guide rail 41 that is attracted by the attracting member 42 is formed. Specifically, the guide rail 41 has a C-shaped channel-shaped guide rail body portion 43 and a suction portion 44 to the suction member 42 . The attracting portion 44 has a plate-like shape, and at least a portion of the surface facing the attracting member 42 is made of a magnetic material. It is set up along the direction.

このような構成であるので、ガイドレール４１の吸着部４４をドア４に設けられた吸着部材４２に吸着させることで、ガイドレール４１をドア４に取り付けることができる。また、吸着部材４２がマグネットから構成されているので、ガイドレール４１をドア４に着脱可能に取り付けることができる。 With such a configuration, the guide rail 41 can be attached to the door 4 by causing the suction portion 44 of the guide rail 41 to be attracted to the suction member 42 provided on the door 4 . Further, since the attracting member 42 is composed of a magnet, the guide rail 41 can be detachably attached to the door 4 .

第１実施形態の場合、ドア４の上端部に枠体９が嵌合される構成であるので、ドア４の上端部とドア枠２との間に十分な隙間がないと、遮蔽装置１をドア４につけたままでドア４の開閉を行うことができない。これに対し、第４実施形態では、ドア４の上端部とドア枠２との間の隙間に部材が位置することがないので、前記隙間が小さい場合でも、遮蔽装置１Ｃをドア４につけたままでドア４の開閉を行うことができる。 In the case of the first embodiment, since the frame 9 is fitted to the upper end of the door 4, if there is not a sufficient gap between the upper end of the door 4 and the door frame 2, the shielding device 1 can be removed. The door 4 cannot be opened/closed while it is attached to the door 4. - 特許庁On the other hand, in the fourth embodiment, since no member is positioned in the gap between the upper end of the door 4 and the door frame 2, even if the gap is small, the shielding device 1C remains attached to the door 4. The door 4 can be opened and closed.

なお、本発明は上記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良は本発明に含まれる。 It should be noted that the present invention is not limited to the above-described embodiments, and includes modifications and improvements within the scope of achieving the object of the present invention.

例えば、上記第１実施形態では、ルーバー７は、所定の角度で開くように付勢されていたが、第１の状態において全閉状態となるように、図示しない付勢部材により所定の付勢力で付勢されていてもよい。この場合、隣接するルーバー７，７同士の隙間が閉塞された全閉状態において、付勢部材による付勢力で隣接するルーバー７，７同士が押し合っている。つまり、隣接するルーバー７，７の端部同士が押し合うことで、複数のルーバー７の全閉状態が維持されている。この状態において、ルーバー７は、開方向に対して前記付勢力を上回る回転力が付加されると通風可能な開状態となる。つまり、ルーバー７は、付勢部材による付勢方向の回転に対して逆方向に回転する。このように、付勢部材は、隣接するルーバー７，７同士の間の隙間を閉塞する閉状態を維持するように、外力によって回転したルーバー７が閉状態に自動復帰するようにルーバー７を回転できる。従って、普段は目隠しを優先するためにルーバー７を全閉状態としておき、風が吹いたときにはルーバー７が開いて通気性を向上させることができる。 For example, in the first embodiment, the louvers 7 are biased to open at a predetermined angle, but the louvers 7 are biased by a biasing member (not shown) so as to be fully closed in the first state. may be energized by In this case, in the fully closed state in which the gap between the adjacent louvers 7, 7 is closed, the adjacent louvers 7, 7 are pressed against each other by the biasing force of the biasing member. That is, the ends of the adjacent louvers 7, 7 are pressed against each other, so that the plurality of louvers 7 are maintained in a fully closed state. In this state, the louver 7 becomes an open state in which ventilation is possible when a rotational force exceeding the biasing force is applied in the opening direction. That is, the louver 7 rotates in a direction opposite to the rotation in the biasing direction of the biasing member. In this way, the biasing member rotates the louvers 7 so that the louvers 7 rotated by an external force automatically return to the closed state so as to maintain the closed state in which the gaps between the adjacent louvers 7 are closed. can. Therefore, the louvers 7 are normally kept in a fully closed state to give priority to blindness, and when the wind blows, the louvers 7 are opened to improve ventilation.

In this case, the adsorption member 26 is provided on the wall surface on the door frame 2 side. That is, in the first state, the other end of the upper support member 6 is connected to the wall surface on the door frame 2 side.

また、上記第３実施形態の構成においてコイルバネ４０が設けられたが、上記第１実施形態及び上記第４実施形態の構成においてコイルバネを設けてもよい。この場合、上部支持部材６は、コイルバネによってドア４側に収容されるように付勢されている。 Moreover, although the coil spring 40 is provided in the structure of the said 3rd Embodiment, you may provide a coil spring in the structure of the said 1st Embodiment and the said 4th Embodiment. In this case, the upper support member 6 is biased by the coil spring so as to be accommodated on the door 4 side.

また、上記第１実施形態及び第４実施形態においてルーバー７が上部支持部材６の長手方向に移動可能に構成してもよいし、上記第２実施形態及び第３実施形態においてルーバー７が支持部材３３の上枠３５及び下枠３６の長手方向に移動可能に構成してもよい。これにより、第１の状態から第２の状態に切り替える際に、ルーバー７を支持する部材の他方の端部にルーバー７を寄せておくことができる。従って、第１の状態から第２の状態に切り替えるためにルーバー７を支持する部材を反時計まわりに回転させる際に、ドアノブ３２とルーバー７とが接触するのを防止できる。 Further, in the first and fourth embodiments, the louvers 7 may be configured to be movable in the longitudinal direction of the upper support member 6, and in the second and third embodiments, the louvers 7 may move along the support member. 33 may be configured to be movable in the longitudinal direction of the upper frame 35 and the lower frame 36 . Thereby, when switching from the first state to the second state, the louver 7 can be brought closer to the other end of the member supporting the louver 7 . Therefore, contact between the doorknob 32 and the louver 7 can be prevented when the member supporting the louver 7 is rotated counterclockwise to switch from the first state to the second state.

また、上記第１実施形態及び第４実施形態では、台座２９によって吸着部材２６の角度が調整されたが、吸着部材を角度調整可能な構成としてもよい。 Further, in the first embodiment and the fourth embodiment, the angle of the adsorption member 26 is adjusted by the pedestal 29, but the angle of the adsorption member may be adjusted.
