　＜映像投射装置または映像投射機能付き照明装置の使用形態＞
　まず、図１および図２は、映像投射装置の一般的な使用形態(天井への設置)を示している。図１は、建造物内の室内のような空間内において、当該空間内に配置された投射面に対して映像投射装置１０が所望の姿勢となるように、建造物の一部または建造物の内装の一部に固定して保持した形態の一例を示している。具体的には、映像投射装置１０を天井面５０から支持ポール３１と取付け部８０を介して下方に吊り下げて、室内の壁面５１に映像が投射されるように装置を所定の位置に取り付けた形態を示している。図１の例では取り付け対象である建造物の一部または建造物の内装の一部の例として、天井面５０の例を示したが、それ以外に壁でもよく、梁でもよく、柱でもよい。その他、内装の一部に映像投射装置１０を固定してもよい。これは、以下の全ての実施例において共通である。 <Usage pattern of video projection device or lighting device with video projection function>
First, FIG. 1 and FIG. 2 show a general usage pattern (installation on the ceiling) of the video projection apparatus. FIG. 1 shows a part of a building or a building so that the image projection apparatus 10 takes a desired posture with respect to a projection surface arranged in the space in a space such as a room in the building. An example of the form fixed and held in a part of the interior is shown. Specifically, the video projection device 10 is suspended downward from the ceiling surface 50 via the support pole 31 and the attachment portion 80, and the device is attached at a predetermined position so that an image is projected onto the indoor wall surface 51. The form is shown. In the example of FIG. 1, an example of the ceiling surface 50 is shown as an example of a part of the building to be attached or a part of the interior of the building, but other than that, a wall, a beam, or a column may be used. . In addition, the video projection device 10 may be fixed to a part of the interior. This is common to all the following embodiments.
　当該固定された取付け部８０に、保持用の部材（本例では、中空の金属部材からなる「支持ポール」）３１を固定し、その先端部に映像投射装置１０を固定する例を示している。電源供給部分は省略しているが、映像投射装置１０の電源ラインを天井付近のコンセントへ接続して使用するものである。なお、この時、映像投射装置１０は、ここでは図示しない調整機構などによって、その投射面が室内の側壁５１に対して、その傾斜角度などを含めての所望の位置・姿勢になるように固定・保持されることは当業者であれば明らかであろう。 An example is shown in which a holding member (in this example, a “support pole” made of a hollow metal member) 31 is fixed to the fixed mounting portion 80 and the image projection device 10 is fixed to the tip portion thereof. . Although the power supply portion is omitted, the power supply line of the video projector 10 is connected to an outlet near the ceiling. At this time, the video projection device 10 is fixed by an adjustment mechanism (not shown) so that the projection surface thereof is in a desired position / posture including the inclination angle with respect to the indoor side wall 51. It will be apparent to those skilled in the art that it is retained.
　図２は、映像投射装置１０を室内の天井面５０から下方に吊り下げて固定し、いわゆる、ポートレート投射と呼ばれる機能を行っている形態を示している。なお、このポートレート投射では、図からも明らかなように、映像投射装置１０は、通常は横方向に設置される装置を縦方向に配置すると共に、室内の天井面５０と床面５２との略中間付近まで降下させた状態で使用されることが多い。また、図１および図２に示した映像投射装置１０では、取付け部８０や支持ポール３１を利用して天井面５０に固定された後、所望の映像が投射面上に投射されるように、壁面を含む映像投射面に対する傾斜角度を含めた位置が設定・調整される。 FIG. 2 shows a mode in which the video projector 10 is suspended and fixed downward from the ceiling surface 50 in the room, and a so-called portrait projection function is performed. In this portrait projection, as is apparent from the figure, the video projection device 10 is provided with devices that are normally installed in the horizontal direction in the vertical direction, and between the ceiling surface 50 and the floor surface 52 in the room. It is often used in a state where it is lowered almost to the middle. In addition, in the video projection device 10 shown in FIGS. 1 and 2, after being fixed to the ceiling surface 50 using the mounting portion 80 and the support pole 31, a desired video is projected onto the projection surface. A position including an inclination angle with respect to the image projection surface including the wall surface is set and adjusted.
　このように、映像投射装置１０を天井に固定して使用する場合、特に、ポートレート投射する場合は、設置する支持ポール３１が長くなるため、人に当たったり、地震などで大きなＧ（加速度）がかかり、固定した天井部分等への大きな負荷により、最悪の場合には、天井部分が破損することもある。そこで、本発明では、支持ポール３１が接続される取付け部８０に衝撃を吸収するダンパ機構を設けることで上述した問題点の解決を図っている。 As described above, when the video projector 10 is used while being fixed to the ceiling, particularly in the case of portrait projection, the support pole 31 to be installed becomes long, so that a large G (acceleration) due to hitting a person, earthquake, etc. In the worst case, the ceiling part may be damaged by a large load on the fixed ceiling part. Therefore, in the present invention, the above-described problem is solved by providing a damper mechanism for absorbing an impact in the mounting portion 80 to which the support pole 31 is connected.
　一方、図３は、上述した映像投射装置と異なり、照明装置内に映像投射機能を搭載した機器であって、特に、天井面に取り付けられる、いわゆる、ペンダント型と呼ばれる照明装置の応用機器（但し、以降は、「照明機能付き映像投射装置１０’」とも言う）の一例である。 On the other hand, FIG. 3 is an apparatus in which an image projection function is installed in the illumination apparatus, unlike the above-described image projection apparatus, and in particular, an application apparatus of a so-called pendant illumination apparatus attached to a ceiling surface (however, Hereinafter, it is also an example of “video projection apparatus with a lighting function 10 ′”).
　なお、この例では、映像投射装置１０’は、例えば、キッチン、ダイニングルーム、または、居間、オフィス等の空間を構成する天井面５０などに取り付けて使用される。より具体的には、図３にも示すように、室内に設置されたテーブルや机６０の上方において、照射面であるテーブルの天板の明るさを確保するため、照射面から一定の距離に設置する。また、当該テーブルまたは机６０の上面（表示面または投射面）６１に様々な映像１を投射して表示する。また、照明機能付き映像投射装置１０’への電源供給は、電力ケーブル(図３では支持ポール３１’の内側に配置)の先端に取り付けられた接続端子（いわゆる引掛けシーリングプラグ端子）を、取付け部８１において、天井面の配線器具７０（いわゆる引掛けシーリング）が有する端子に接続することで行われる。 In this example, the video projection device 10 ′ is used by being attached to, for example, a kitchen, a dining room, or a ceiling surface 50 constituting a space such as a living room or an office. More specifically, as shown in FIG. 3, above the table or desk 60 installed indoors, in order to ensure the brightness of the table top, which is the irradiation surface, at a certain distance from the irradiation surface. Install. Further, various images 1 are projected and displayed on the upper surface (display surface or projection surface) 61 of the table or desk 60. Further, the power supply to the image projection apparatus 10 ′ with the illumination function is performed by attaching a connection terminal (so-called hook ceiling plug terminal) attached to the tip of the power cable (arranged inside the support pole 31 ′ in FIG. 3). In the part 81, it connects by connecting with the terminal which the wiring fixture 70 (what is called hook ceiling) of a ceiling surface has.
　一般にペンダント型の照明装置は、電源ケーブルを利用して設置されるが、同様に照明機能付き映像装置１０’を電源ケーブルのみで設置した場合、装置本体が振動したり回転したりして、なかなか静止状態とならない事態が発生し、また、一旦静止状態となっても、その後、人が当たったり、地震が発生した場合には、揺れが再発してしまい、投射した映像が揺れ、見ている人の気分が悪くなる（不快感を与える）。そこで、金属もしくは強度の高い樹脂材などの支持ポール(図３の３１’)を利用することにより天井面に対して固定し、これにより振動および回転から防ぐことが考えられる。 Generally, a pendant type lighting device is installed using a power cable. Similarly, when the video device 10 ′ with a lighting function is installed using only the power cable, the device main body vibrates or rotates. When a situation that does not become stationary occurs, and once it becomes stationary, when a person hits it or an earthquake occurs, the shaking recurs, and the projected image shakes and looks The person feels uncomfortable (provides discomfort). Therefore, it is conceivable to use a support pole (31 'in FIG. 3) such as a metal or a high-strength resin material to fix it to the ceiling surface, thereby preventing vibration and rotation.
　以上、説明した２例(映像投射装置１０と照明機能付き映像投射装置１０’)は電源供給部分を除くと、天井５０への固定の仕方はほぼ同様である。
　しかしながら、上述した図１および図２に示した映像投射装置１０と、図３、図４に示した照明機能付き映像投写装置１０’に関しては、強い衝撃が加わった時や地震等で大きな加速度が加わった時には、支持ポール(３１、３１’)自体が曲がるか、あるいは、天井部分が破損するなどの問題が生じる。また、人の頭が当たったりすると怪我をする場合もある。そこで、本発明では、支持ポールや天井の破損を避けるために、ダンパ機構を有する固定部および支持ポールにより固定して設置することで、画面の不快な揺れを防止・抑制すると共に、衝撃が加わった時の装置の破損や人の怪我などを防止する。 The two examples described above (the video projection device 10 and the video projection device 10 ′ with illumination function) are substantially the same in fixing to the ceiling 50 except for the power supply portion.
However, the image projection apparatus 10 shown in FIGS. 1 and 2 and the image projection apparatus 10 ′ with an illumination function shown in FIGS. 3 and 4 have a large acceleration when a strong impact is applied or an earthquake occurs. When added, problems such as bending of the support poles (31, 31 ′) themselves or breakage of the ceiling occur. In addition, people may be injured if they hit their heads. Therefore, in the present invention, in order to avoid damage to the support pole and the ceiling, it is fixed and installed by a fixing portion having a damper mechanism and the support pole, thereby preventing and suppressing unpleasant shaking of the screen and applying an impact. This prevents damage to the equipment and personal injury.
　このように、映像投射装置１０（特に、図２を参照）やペンダント型の照明機能付き映像投射装置１０’（図３を参照）は、いずれの場合においても、映像投射装置１０、１０’が人体や物に、例えば、ユーザの頭部に接触してしまうことが多く見受けられる。そのため、かかる場合における接触による衝撃からユーザの安全を確保すると共に、当該衝撃による破損から映像投射装置１０、１０’を保護することが強く求められる。なお、かかる状況は、地震発生の際にも同様に発生する。 As described above, in any case, the video projection device 10 (see FIG. 2) and the pendant-type video projection device 10 ′ with illumination function (see FIG. 3) are the same as the video projection device 10, 10 ′. It is often seen that a human body or an object, for example, comes into contact with the user's head. Therefore, it is strongly required to secure the safety of the user from the impact caused by the contact in such a case and to protect the video projection devices 10 and 10 'from the damage caused by the impact. This situation also occurs when an earthquake occurs.
　＜映像投射装置のための安全システム＞
　かかる課題に対して、本発明の映像投射装置１０や映像投射装置１０’では、映像投射装置１０’を保持する取付け部８０、８１に弾性体などを用いた衝撃吸収機構を組み込むこととする。具体的には、ここでは、上記図３の映像投射装置１０’の場合についてのみ示すが、支持ポール３１’が固定される取付け部８１内に衝撃吸収用のダンパ（例えば、バネ等）を組み込んで、衝突や接触の際の衝撃を吸収するものである。 <Safety system for video projector>
In order to deal with this problem, in the video projection device 10 and the video projection device 10 ′ of the present invention, an impact absorbing mechanism using an elastic body or the like is incorporated in the mounting portions 80 and 81 that hold the video projection device 10 ′. Specifically, here, only the case of the image projection apparatus 10 ′ of FIG. 3 is shown, but a shock absorbing damper (for example, a spring) is incorporated in the mounting portion 81 to which the support pole 31 ′ is fixed. Thus, it absorbs the impact at the time of collision or contact.
　これによれば、図４にもその一例を示すように、金属もしくは強度の高い樹脂材などの剛体からなる支持ポール３１’を利用することにより、映像投射装置を天井面に対して固定して取り付け、これにより、設置時や通常使用の際における装置の振動や回転を防止することが可能となる。更には、衝突や接触等により映像投射装置１０’が衝撃を受けると、支持ポール３１’は、衝撃吸収用ダンパの働きにより、加わる衝撃に応答してその位置を天井面５０に固定された取付け部８１に対して移動する（即ち、傾斜する）。これにより、衝撃を吸収および／または緩和してユーザの安全を確保すると共に、映像投射装置１０’を破損から保護する。その後、支持ポール３１’は、ダンパの働きにより、その振動が吸収され、再び、元の位置に戻ろうとする。 According to this, as shown in FIG. 4 as an example, by using a support pole 31 ′ made of a rigid body such as a metal or a high-strength resin material, the image projection device is fixed to the ceiling surface. Mounting, thereby preventing vibration and rotation of the device during installation and normal use. Furthermore, when the video projection device 10 ′ receives an impact due to a collision or contact, the support pole 31 ′ is fixed to the ceiling surface 50 in response to the applied impact by the action of the shock absorbing damper. It moves (i.e., tilts) relative to the portion 81. Thereby, the impact is absorbed and / or alleviated to ensure the safety of the user, and the video projection device 10 ′ is protected from breakage. Thereafter, the vibration of the support pole 31 ′ is absorbed by the action of the damper and tries to return to the original position again.
　しかしながら、図４に示すように、振動吸収のみ重視したダンパ機能においては、映像投射装置１０’が正常な位置からずれ、映像が予め設定された所望の位置から外れた位置に歪んで（または、変形して）投射されてしまい、振動が停止した後、再度、映像投射装置１０’の位置調整が必要となってしまう。 However, as shown in FIG. 4, in the damper function that emphasizes only vibration absorption, the video projection device 10 ′ is displaced from the normal position, and the video is distorted to a position deviating from a preset desired position (or After the projection is performed and the vibration is stopped, it is necessary to adjust the position of the video projection device 10 ′ again.
　このように、照明機能付き映像投射装置１０’では、装置の振動や回転により、当該装置により投射される映像の位置、大きさ、歪などが、大きく影響されてしまい、また、ユーザは、映像投射装置１０’が衝突した後に復帰したとしても、再度、予め設定した位置に設定し直す必要があり、ユーザにとっては面倒な作業であった。これは、図１および図２に示した映像投射装置１０においても同様である。 As described above, in the video projection device 10 ′ with the illumination function, the position, size, distortion, and the like of the video projected by the device are greatly affected by the vibration and rotation of the device. Even if the projection apparatus 10 ′ returns after colliding, it is necessary to reset the position to a preset position again, which is troublesome for the user. The same applies to the video projection apparatus 10 shown in FIGS. 1 and 2.
　即ち、所望の映像を拡大して投射する映像投射装置１０、および照明機能付き映像投射装置１０’では、その取り付け装置である天井吊り下げ装置にとって、（１）投射された画面の揺れを抑制して速やかに静止されること（揺れる映像を見ている人への不快・不安感を防止する）、（２）人体などの衝突や接触に対しても、映像投射装置を破損から保護すると共に、ユーザの安全を確保すること、そして、（３）投射面に対する位置ずれをも含め、振動後の映像投射装置を、映像投射装置の揺れを抑制して、投射面への投射状態を速やかに予め設定した元の位置に戻すことが重要である。 That is, in the video projection device 10 that projects a desired video in an enlarged manner and the video projection device with a lighting function 10 ′, for the ceiling suspension device that is the mounting device, (1) it suppresses the shake of the projected screen. (2) to protect the image projection device from damage, even against collisions and contact with the human body, etc. Ensuring the safety of the user, and (3) suppressing the shaking of the video projection device, including the positional deviation with respect to the projection surface, quickly controlling the projection state on the projection surface in advance. It is important to return to the original position.
　そこで、本発明では、上述した問題点を解消し、即ち、照明機能付き映像投射装置１０’を天井面５０から下方に吊り下げて固定して保持することが可能であり、かつ、映像投射装置１０’への衝撃に対しても、ユーザの安全の確保と装置の破損からの保護を可能とすると共に、更に、衝突後においても、映像投射装置１０’がその揺れを抑制しながら、速やかに自律的に予め設定した位置に戻ることを可能とする。このことにより、ユーザにとって面倒な位置の再度設定の必要のない、実用的にも便利で、優れた天井吊り下げ装置を提案するものである。そして、更には、天井吊り下げ装置である取付け装置を含めた映像投射装置のための安全システムを実現するものである。 Therefore, in the present invention, it is possible to solve the above-described problems, that is, it is possible to suspend and hold the video projection device 10 ′ with an illumination function downward from the ceiling surface 50 and to hold the video projection device. It is possible to ensure the safety of the user and protect the device from damage even against an impact on the 10 ′, and even after the collision, the video projection device 10 ′ can quickly suppress the shaking. It is possible to autonomously return to a preset position. Accordingly, the present invention proposes an excellent ceiling suspending device that is practically convenient and does not require the user to set a troublesome position again. Further, a safety system for a video projection device including an attachment device that is a ceiling suspension device is realized.

　なお、この固定部２０は、これらの図からも明らかなように、例えば、円盤状の外形を有する金属製の部材であり、その底面を上記配線器具７０の底面７２へ当接すると共に、ネジ２１によって固定されている。即ち、固定部２０は、天井面５０に対して固定して取り付けられる。 As is apparent from these drawings, the fixing portion 20 is, for example, a metal member having a disk-shaped outer shape. The fixing portion 20 abuts on the bottom surface 72 of the wiring device 70 and the screw 21. It is fixed by. That is, the fixed portion 20 is fixedly attached to the ceiling surface 50.
　また、この固定部２０の底面には、下方に向かって突出する３本の棒状部材２２が設けられている。なお、これら３本の棒状部材２２は、本例では、互いに同じ長さを有しており、その端部（下端）には、リング状の留め部材２３を固定するためのネジ溝（図示せず）が形成されている。更に、これら３本の棒状部材２２の周囲には、それぞれ、以下にも詳述する復帰用の押圧バネ２４が設けられており、これらの押圧バネ２４は、上記固定部２０の底面とリング状の留め部材２３との間に保持される（特に、図８を参照）。 Further, three rod-like members 22 projecting downward are provided on the bottom surface of the fixed portion 20. The three rod-like members 22 have the same length in this example, and a screw groove (not shown) for fixing the ring-like fastening member 23 is provided at the end (lower end) thereof. ) Is formed. Further, a return pressing spring 24, which will be described in detail below, is provided around each of the three rod-shaped members 22, and these pressing springs 24 are formed in a ring shape with the bottom surface of the fixing portion 20. (See FIG. 8 in particular).
　一方、可動部３０は、本例では、例えば、三角状の外形を有する金属製の部材から構成されおり、その底面には、上述した映像投射装置の吊り下げ部材である中空状の支持ポール３１が、ネジ３２等を介して固定されている。より正確には、可動部３０の底面に支持ポール保持部材３４がネジ３２により固定され、支持ポール保持部材３４の一端に設けられたネジ部に大径ネジ３５が嵌合し、もって、支持ポール３１を可動部３０に固定する。その結果、これら可動部３０と支持ポール３１とは一体となっている。あるいは、支持ポール３１の上端には上記三角形状の可動部３０が鍔状に取り付けられた構造となっている（特に、図９を参照）。また、三角形状の可動部３０の各角部には、それぞれ、開口部３３が形成されている。 On the other hand, in this example, the movable portion 30 is made of, for example, a metal member having a triangular outer shape, and a hollow support pole 31 that is a suspension member of the above-described video projector is formed on the bottom surface thereof. Is fixed via a screw 32 or the like. More precisely, the support pole holding member 34 is fixed to the bottom surface of the movable portion 30 by the screw 32, and the large diameter screw 35 is fitted to the screw portion provided at one end of the support pole holding member 34. 31 is fixed to the movable part 30. As a result, the movable part 30 and the support pole 31 are integrated. Alternatively, the triangular movable portion 30 is attached to the upper end of the support pole 31 in a bowl shape (see particularly FIG. 9). In addition, an opening 33 is formed at each corner of the triangular movable portion 30.
　そして、これらの固定部２０と可動部３０は、図６に示すように、互いに、上述した３本の復帰用押圧バネ２４を間に挟んで組み立てられている。より詳細には、固定部２０の底面から下方に延びた３本の棒状部材２２を、各々、押圧バネ２４を所定量圧縮して取り付けた状態で、三角形状の可動部３０の各角部に設けた開口部３３を貫通させた後、リング状の留め部材２３をネジ止めする。また、図７における符号４０は、上記固定部２０と可動部３０を取り囲んで形成されたケーシング部材であり、また、符号７６は、上記配線器具７０からの商用電源を、天井吊り下げ装置に取り付けられた映像投射装置へ供給するため、支持ポール３１の内部に収納されたケーブルを示す。なお、ケーブルを収納することのメリットとしては、例えば、衝撃吸収の動作時に経路長の変化を少なくすることができるため、衝撃吸収の動作を妨げない、更には、ケーブルの保護などが挙げられる。 Then, as shown in FIG. 6, the fixed portion 20 and the movable portion 30 are assembled with the above-described three return pressing springs 24 interposed therebetween. More specifically, each of the three rod-like members 22 extending downward from the bottom surface of the fixed portion 20 is attached to each corner of the triangular movable portion 30 with the pressing springs 24 compressed by a predetermined amount. After passing through the provided opening 33, the ring-shaped fastening member 23 is screwed. Further, reference numeral 40 in FIG. 7 is a casing member formed so as to surround the fixed part 20 and the movable part 30, and reference numeral 76 attaches a commercial power source from the wiring device 70 to the ceiling hanging device. The cable accommodated in the support pole 31 for supply to the image projection apparatus is shown. The advantages of housing the cable include, for example, that the change in path length can be reduced during the shock absorbing operation, so that the shock absorbing operation is not hindered, and the cable is protected.
　以上に詳述した本実施の形態に係る取付け装置によれば、図７や図１０の概念図にも示すように、固定部２０は、天井面５０に対して配線器具７０を介して固定されて取り付けられていることから、当該固定部２０の底面から下方に延びた３本の棒状部材２２の端部（下端）は、上記天井面５０に対して固定された平面（以下、「基準面」とも言う）を形成する。換言すれば、固定部２０は、可動部３０と共に、鉛直方向の位置決め部と共に、回転方向の位置決め部を形成しており、これにより、その鉛直方向および回転方向の移動を規制する。このことにより、映像投射装置の揺れを抑制しながら、可動部３０のより迅速な元の位置への自律的な復帰を可能にしている。 According to the mounting apparatus according to the present embodiment described in detail above, the fixing portion 20 is fixed to the ceiling surface 50 via the wiring device 70 as shown in the conceptual diagrams of FIGS. Therefore, the end portions (lower ends) of the three rod-like members 22 extending downward from the bottom surface of the fixed portion 20 are fixed to the ceiling surface 50 (hereinafter referred to as “reference surface”). ”). In other words, the fixed part 20 forms a rotational positioning part together with the movable part 30 together with the vertical positioning part, thereby restricting the movement in the vertical direction and the rotational direction. As a result, it is possible to autonomously return the movable unit 30 to the original position more quickly while suppressing the shaking of the video projection device.
　他方、可動部３０は、上記押圧バネ２４により下方に押されて３本の棒状部材２２の端部（下端）で停止されることから、可動部３０の三角形状の面（「移動面」とも言う）は、上述した基準面に対して平行な面に沿って配置されることとなる。なお、上記の説明では、可動部３０の三角形状の移動面は、基準面に対して平行な面に沿って配置されるものと述べたが、しかしながら、本発明はこれに限定されることなく、例えば、棒状部材の端部のリング状留め部材の位置を調整することで、「基準面」に対する「移動面」の傾きを可変とすることも可能である。 On the other hand, the movable portion 30 is pressed downward by the pressing spring 24 and stopped at the end portions (lower ends) of the three rod-shaped members 22, so that the triangular surface (the “moving surface”) of the movable portion 30 is also used. Are arranged along a plane parallel to the reference plane described above. In the above description, it has been described that the triangular moving surface of the movable portion 30 is disposed along a plane parallel to the reference plane. However, the present invention is not limited to this. For example, the inclination of the “moving surface” with respect to the “reference surface” can be made variable by adjusting the position of the ring-shaped retaining member at the end of the rod-shaped member.
　そして、可動部３０は、所定量以下の外力、例えば風などの場合は、押圧バネ２４により不用意に移動することはない。他方、所定量以上の外力、例えば、人体や物等の映像投射装置への接触や地震等により衝撃が発生した場合には、可動部３０（可動面）は、上記押圧バネ２４に抗して移動し、その底面に固定された支持ポール３１を移動可能にする（即ち、傾斜する）。ケーシング部材４０の開口部４１は、支持ポール３１の移動範囲よりも大きいため、可動部３０の移動を妨げることがなく、またケーシング部材４０を破損することもない。これにより、衝撃を吸収および／または緩和してユーザの安全を確保すると共に、映像投射装置を破損から保護する。 And the movable part 30 does not move carelessly by the pressing spring 24 in the case of an external force of a predetermined amount or less, such as wind. On the other hand, when an impact is generated due to an external force of a predetermined amount or more, for example, contact with an image projection device such as a human body or an object or an earthquake, the movable portion 30 (movable surface) resists the pressing spring 24. The support pole 31 fixed to the bottom surface of the support pole 31 is moved (ie, tilted). Since the opening 41 of the casing member 40 is larger than the movement range of the support pole 31, the movement of the movable portion 30 is not hindered and the casing member 40 is not damaged. Accordingly, the impact is absorbed and / or alleviated to ensure the safety of the user, and the video projection apparatus is protected from damage.
　その後、本実施の形態（実施例１）に係る取付け装置によれば、可動部３０の可動面は、上記押圧バネ２４の働きによって押し戻されるが、その際、固定部２０の３本の棒状部材２２の端部（下端：基準面を形成）で停止される。このことから、可動部３０の可動面は、映像投射装置の揺れを抑制しながら、上述した鉛直方向の位置決め部や回転方向の位置決め部の働きなどによって、速やかに、再度、基準面またはそれに対して平行な面に戻る。即ち、元の設定位置に復帰することが可能となる。 Thereafter, according to the attachment device according to the present embodiment (Example 1), the movable surface of the movable portion 30 is pushed back by the action of the pressing spring 24. At this time, the three rod-shaped members of the fixed portion 20 are pressed. Stopped at the end 22 (lower end: forming a reference plane). From this, the movable surface of the movable unit 30 can quickly and again be brought into contact with the reference surface or the same by the functions of the vertical positioning unit and the rotational positioning unit described above while suppressing the shaking of the video projection device. And return to a parallel plane. That is, it is possible to return to the original setting position.
　このように、本実施の形態（実施例１）に係る取付け装置によれば、映像投射装置１０’への衝撃に対しても、ユーザの安全の確保や装置の破損からの保護が可能であり、衝突後においても、映像投射装置の揺れを抑制しながら、映像投射装置の元の設定位置への速やかな自律的復帰が可能となり、面倒な位置の再度設定をする必要もなく、ユーザにとっては非常に便利である。
　（実施例２） As described above, according to the mounting device according to the present embodiment (Example 1), it is possible to ensure the safety of the user and protect the device from damage even against an impact on the video projection device 10 ′. Even after a collision, while suppressing the shaking of the video projection device, it is possible to quickly return to the original setting position of the video projection device, and it is not necessary to set the troublesome position again. Very convenient.
(Example 2)
　続いて、本発明の他の実施の形態（実施例２）に係る取付け装置について、図１１～図１４を参照しながら詳細に説明する。なお、この他の実施の形態（実施例２）では、例えば、配線器具７０の底面７２へ当接して取り付けることによって天井面５０に対して固定した固定部２０は、上記と同様に、円盤状の外形を有する金属製の部材により構成されると共に、円筒状部材２５を備えている。なお、この円筒状部材２５の底面２６の一部に開口部２７が形成されている。また、この円筒状部材２５の上端には鍔状部２８が形成されており、上記と同様に、この鍔状部２８を固定部２０へ当接して、例えば、ここでは図示しないネジ２１等によって固定される。 Subsequently, an attachment apparatus according to another embodiment of the present invention (Example 2) will be described in detail with reference to FIGS. In this other embodiment (Example 2), for example, the fixed portion 20 fixed to the ceiling surface 50 by being in contact with and attached to the bottom surface 72 of the wiring device 70 is a disc-like shape as described above. And a cylindrical member 25 is provided. An opening 27 is formed in a part of the bottom surface 26 of the cylindrical member 25. In addition, a hook-like portion 28 is formed at the upper end of the cylindrical member 25. Similarly to the above, the hook-like portion 28 is brought into contact with the fixed portion 20 and is, for example, screwed by a screw 21 not shown here. Fixed.
　また、この円筒状部材２５の底面２６には、上記実施例１における３本の棒状部材に替えて、特に、図１３および図１４から明らかなように、３個の着座部材２９がネジ２９１等により固定されている。なお、符号２９２は、着座部材２９と一体に形成されたガイド部を示している。 Further, on the bottom surface 26 of the cylindrical member 25, in place of the three rod-like members in the first embodiment, particularly as shown in FIGS. 13 and 14, three seating members 29 are provided with screws 291 and the like. It is fixed by. Reference numeral 292 denotes a guide portion formed integrally with the seating member 29.
　一方、可動部３０は、上記実施例１の三角状の金属製部材に替えて、本例では、特に、図１４から明らかなように、３本の棒状部材３４を支持ポール３１の端（上端）部に一体に取り付けることにより形成されている。 On the other hand, the movable part 30 is replaced with the triangular metal member of the first embodiment, and in this example, as is apparent from FIG. It is formed by attaching to the part).
　そして、図１１および図１２に示すように、可動部３０は、一体に取り付けた支持ポール３１を、固定部２０の円筒状部材２５の底面２６に形成された開口部２７内に挿入した状態で、その上端部に取り付けた３本の棒状部材３４が、円筒状部材２５の底面２６に形成された３か所の突起部２５１により鉛直方向の位置決めをされ、着座部材２９のガイド部２９２により回転方向の位置決めがされる。更に、その上には、実施例１の３本の押圧バネ２４に替えて、１本の押圧バネ２４’が取り付けられて、固定部２０を構成する円盤状の部材との間に取り付けられ、棒状部材３４を、ひいては可動部３０を、円筒状部材２５に押圧する。 As shown in FIGS. 11 and 12, the movable portion 30 is in a state in which the support pole 31 attached integrally is inserted into the opening portion 27 formed in the bottom surface 26 of the cylindrical member 25 of the fixed portion 20. The three rod-shaped members 34 attached to the upper end portions thereof are positioned in the vertical direction by the three protrusions 251 formed on the bottom surface 26 of the cylindrical member 25 and rotated by the guide portion 292 of the seating member 29. Directional positioning is performed. Furthermore, in place of the three pressing springs 24 of the first embodiment, one pressing spring 24 ′ is attached, and is attached between the disk-shaped members constituting the fixing portion 20. The rod-shaped member 34 and thus the movable part 30 are pressed against the cylindrical member 25.
　上述した実施例２に係る取付け装置の構成によれば、上記の図１０により説明したと同様に、固定部２０を構成する円筒状部材２５の３個の突起部２５１が、天井面５０に対して固定された平面である基準面を形成している。他方、可動部３０では、支持ポール３１の上端に固定された３本の棒状部材３４は、１本の押圧バネ２４’により下方に押されていることから、３個の突起部２５１の位置で停止し、基準面またはそれに対して平行な面に位置することとなる。 According to the configuration of the mounting device according to the second embodiment described above, the three projecting portions 251 of the cylindrical member 25 constituting the fixing portion 20 are formed on the ceiling surface 50 in the same manner as described with reference to FIG. A reference plane which is a fixed plane is formed. On the other hand, in the movable portion 30, the three rod-shaped members 34 fixed to the upper end of the support pole 31 are pressed downward by the single pressing spring 24 ′, so that at the position of the three protruding portions 251. It stops and is positioned on the reference plane or a plane parallel to the reference plane.
　そして、人体や物などの映像投射装置への接触や地震等により映像投射装置１０’に衝撃が発生した場合には、可動部３０は、上記１本の押圧バネ２４’に抗して移動することにより、その底面に固定された支持ポール３１を移動可能にする（即ち、傾斜する）。これにより、衝撃を吸収および／または緩和してユーザの安全を確保すると共に、映像投射装置を破損から保護する。 When an impact occurs on the video projection device 10 ′ due to contact with the video projection device such as a human body or an object or an earthquake, the movable unit 30 moves against the one pressing spring 24 ′. As a result, the support pole 31 fixed to the bottom surface of the support pole 31 can be moved (that is, inclined). Accordingly, the impact is absorbed and / or alleviated to ensure the safety of the user, and the video projection apparatus is protected from damage.
　その後、この実施例２に係る取付け装置によれば、上記と同様に、その可動部３０は、上記１本の押圧バネ２４’の働きによって押し戻され、３個の突起部２５１および着座部材２９の位置で停止する。これにより、可動部３０は、映像投射装置の揺れを抑制しながら、上述した鉛直方向の位置決め部や回転方向の位置決め部の働きなどによって、速やかに、再度、基準面またはそれに対して平行な面に戻り、元の設定位置に復帰することが可能となる。 Thereafter, according to the attachment device according to the second embodiment, the movable portion 30 is pushed back by the action of the one pressing spring 24 ′ as described above, and the three projecting portions 251 and the seating member 29 are moved. Stop at position. As a result, the movable unit 30 can quickly and again revert to the reference plane or a plane parallel to the reference plane by the functions of the vertical positioning unit and the rotational positioning unit described above while suppressing the shaking of the video projection device. It becomes possible to return to the original setting position.
　即ち、この実施例２に係る取付け装置も、上記と同様に、映像投射装置１０’への衝撃に対してユーザの安全の確保や装置の破損からの保護が可能であり、衝突後においても、映像投射装置の揺れを抑制しながら、映像投射装置の元の設定位置への速やかな自律的復帰が可能となり、面倒な位置の再度設定の必要もなく、ユーザにとっては非常に便利である。 That is, in the same manner as described above, the mounting device according to the second embodiment can ensure the safety of the user and protect the device from damage to the impact on the video projection device 10 ′. While suppressing the shaking of the video projection device, it is possible to quickly return to the original setting position of the video projection device, and it is not necessary to set the troublesome position again, which is very convenient for the user.
　続いて、図１５により、上述した映像投射装置のうち、代表的な図３に示した照明装置に映像投射機能を搭載した照明機能付き映像投射装置１０’の内部構造の一例を示す。 Subsequently, FIG. 15 shows an example of the internal structure of a video projection device 10 ′ with an illumination function in which the video projection function is mounted on the illumination device shown in FIG.

It has a fixed configuration. That is, the holding unit 200 is mounted with the optical unit 300, and in the vicinity of the lower end thereof, an annular LED substrate 420 is also formed on the surface of the annular aluminum heat sink 410, A so-called illumination LED 400 in which a plurality of illumination LEDs 430 are arranged on the substrate surface is horizontally mounted.

Below that, although not shown here, for example, a fan bracket made of a disk-shaped metal plate is horizontally mounted, and on the upper surface thereof, for example, a fan which is a blowing means made of an axial fan or an electric motor A cooling mechanism for discharging the air in the shade 110 to the outside through the louver 650 is configured.
　また、上記保持部材２００の他の面には、ヒートパイプ７１０を介してヒートシンク７００が取り付けられており、光学ユニット部３００が発生する熱をシェード１１０内部の空気流に伝達して必要な放熱を図っている。 In addition, a heat sink 700 is attached to the other surface of the holding member 200 via a heat pipe 710, and heat generated by the optical unit 300 is transmitted to an air flow inside the shade 110 to dissipate necessary heat. I am trying.
　図１６は、上述した照明機能付き映像投射装置１０’の回路構成の一例を示すブロック図である。 FIG. 16 is a block diagram illustrating an example of a circuit configuration of the above-described video projection device with a lighting function 10 ′.
　この図からも明らかなように、映像投射装置１０’は、概略すると、電源を必要なＡＣまたはＤＣ電力に変換するＡＣ／ＤＣ電源５００と、照明機能を実現するための照明部２００と、そして、映像投射装置として光学ユニット部３００とから構成されている。 As is apparent from this figure, the video projection apparatus 10 'roughly includes an AC / DC power source 500 for converting the power source into necessary AC or DC power, an illumination unit 200 for realizing an illumination function, and The optical projection unit is composed of an optical unit 300.
　照明部２００は、その外部から（例えば、以下にも述べる光学ユニット部３００のマイコン１７３０等から）の制御信号を入力して駆動電流を制御するＬＥＤドライバ４４０を備えており、これにより、ＬＥＤ基板４２０の表面に配置された照明用のＬＥＤ４３０は、当該ＬＥＤドライバ４４０から供給される電流により、適宜、駆動される。 The illumination unit 200 includes an LED driver 440 that receives a control signal from the outside (for example, from the microcomputer 1730 of the optical unit unit 300 described below) and controls a drive current, and thereby an LED substrate. The illumination LED 430 arranged on the surface of 420 is appropriately driven by the current supplied from the LED driver 440.
　光学ユニット部３００は、ここでは図示しない操作信号入力部から操作ボタンやリモコン等を介してユーザからの操作信号を入力して、各種の制御信号を出力するマイコン１７０３を含んでおり、当該マイコン１７０３からの制御信号の１つは、上述した照明部２００へ出力されると共に、光学ユニット部３００を構成するパネルドライバ１７１２や光源駆動部１７１７、更には、音声処理部２４０５へ出力される。パネルドライバ１７１２は、パネル制御信号に基づいて、ＬＣＤやＤＭＤ（Ｄｉｇｉｔａｌ　Ｍｉｃｒｏｍｉｒｒｏｒ　Ｄｅｖｉｃｅ：登録商標）等から構成されるパネル１７１３上に表示される映像を制御すると共に、光源制御信号は、光源駆動部１７１７を介して、映像投射機の光源を構成するＬＥＤ光源１７１６を駆動・制御し、レンズやミラーを含む照明光学系１７１５を介して照明光をパネル１７１３上に照射する。これにより、照明光学系１７１５からの照明光は、パネル１７１３により変調されて映像光となり、投射レンズやミラーを含む投射光学系１７１４を介して設定された投射面上に投射される。また、音声信号も、同様に、音声処理部２４０５により変換されたてスピーカー２４０６に供給されて音声として出力される。 The optical unit unit 300 includes a microcomputer 1703 that inputs an operation signal from a user from an operation signal input unit (not shown) via an operation button, a remote controller, or the like, and outputs various control signals. One of the control signals is output to the illumination unit 200 described above, and is also output to the panel driver 1712 and the light source driving unit 1717 constituting the optical unit unit 300 and further to the sound processing unit 2405. The panel driver 1712 controls an image displayed on a panel 1713 including an LCD, DMD (Digital Micromirror Device: registered trademark), and the like based on the panel control signal, and the light source control signal is a light source drive unit 1717. The LED light source 1716 that constitutes the light source of the video projector is driven and controlled via the, and the illumination light is irradiated onto the panel 1713 via the illumination optical system 1715 including a lens and a mirror. Thereby, the illumination light from the illumination optical system 1715 is modulated by the panel 1713 to become image light, and is projected onto the projection plane set via the projection optical system 1714 including the projection lens and mirror. Similarly, the audio signal is converted by the audio processing unit 2405 and supplied to the speaker 2406 to be output as audio.
　以上説明したように、光学ユニット部３００には様々な機能を載せることが可能であるが、しかしながら、必ずしも上述した構成の全てを有する必要はなく、基本的には、映像を投射する機能がある構成であればよい。 As described above, the optical unit 300 can have various functions. However, it is not always necessary to have all of the above-described configurations, and basically has a function of projecting an image. Any configuration may be used.
　上述した本発明の各実施例の映像投射装置の取付け装置とそれを含めた映像投射システムによれば、人体が映像投射装置の一部に接触した場合や地震等の場合においても、映像投射装置やユーザをその衝撃から保護すると共に、その際に生じる映像投射装置から投射された映像画面の望ましくない揺れを速やかに静止して当該装置を元の姿勢に戻すことができ、これは、ユーザにとって安全かつ安心な映像投射システムとそのための映像投射装置の取付け装置と言える。即ち、本発明によれば、ユーザによってより好適な映像投射装置の取付け装置またはそれを含めた映像投射システムを提供できる。 According to the video projection apparatus mounting apparatus and the video projection system including the video projection apparatus according to each embodiment of the present invention described above, the video projection apparatus can be used even when the human body contacts a part of the video projection apparatus or in the case of an earthquake or the like.
