Description

本発明は、薄板天井に穴を開けた天井に取り付けるスピーカ、監視カメラ、無線アンテナ装置などを施工時に多数の工具を使わずに簡便、確実に保持できる穴開き天井固定装置に関する。   The present invention relates to a perforated ceiling fixing device that can easily and reliably hold a speaker, a surveillance camera, a wireless antenna device, and the like attached to a ceiling with a hole in a thin plate ceiling without using many tools during construction.

最近の商業用建築物の天井は薄板金属で施工される傾向にあり、施工時、施工後に天井に取り付けるスピーカ、監視カメラ、無線アンテナ装置などがある。天井は薄い為にネジ穴を開ける方法ではネジで固定できない、天井に手が入ればネジとナットで締結することが出来るがベースを天井に合わせると手が天井に入れて作業が出来なくなる。作業者は床から梯子などで登り、上を見ながらの苦しい姿勢で作業する状態で、又、取り付けが確実に行われていることを取り付け後に外部から確認することが出来なかった。   Recent commercial building ceilings tend to be constructed of sheet metal, including speakers, surveillance cameras, and wireless antenna devices that are attached to the ceiling during and after construction. Since the ceiling is thin, it cannot be fixed with screws by the method of drilling screw holes. If the hand enters the ceiling, it can be fastened with screws and nuts, but if the base is aligned with the ceiling, the hand cannot enter the ceiling and work. The worker climbed on the ladder from the floor and worked in a difficult posture while looking at the top. Also, it was not possible to confirm from the outside after installation that the installation was performed securely.

天井に取り付けるスピーカ、監視カメラ、無線アンテナ装置などは主装置を天井穴に合わせると手先が天井裏に入ることは不可能に近い。且つ、作業姿勢が天井を眺めながらのため複数の工具を取り替えて使用することも困難がある。取り付けた後に確実に保持されていることを確認することが困難であった。   Speakers, surveillance cameras, wireless antenna devices, and the like that are attached to the ceiling are nearly impossible to put into the back of the ceiling when the main device is aligned with the ceiling hole. In addition, since the working posture is looking at the ceiling, it is difficult to use a plurality of tools by replacing them. It was difficult to confirm that it was securely held after mounting.

そこで本発明は、製品出荷時に天井に固定する固定片が締め付け保持され、固定ネジを緩め、固定片が開けられた取り付け穴から薄板天井の方向に回転溝の中を回転し、溝に遮られ止り、固定ネジを反対方向に回転させることで薄板天井に締め付けることができる。固定片が適正な位置で止まっているかを目視確認でき、もし、適正位置ではない場合には固定ネジを緩め固定片が露出されたクランク形状を指で適正位置に動かすことができる利便性の向上を図ることができるようにした。   Therefore, in the present invention, the fixing piece to be fixed to the ceiling is tightened and held at the time of product shipment, the fixing screw is loosened, the mounting piece in which the fixing piece is opened rotates in the rotating groove in the direction of the thin plate ceiling, and is blocked by the groove. It can be fastened to the thin ceiling by rotating the fixing screw in the opposite direction. It is possible to visually check whether the fixed piece is stopped at the proper position. If it is not the correct position, loosen the fixing screw and improve the convenience of moving the crank shape with the fixed piece exposed to the proper position with your finger. I was able to plan.

本発明は、天井に取り付けるスピーカ、監視カメラ、無線アンテナ装置は薄板天井に穴を開け、穴の大きさは直径約200mm程度で、ベースにはそれぞれの機器が具備されている。ベースには複数の固定ネジを中心に回転に伴う角度の回転溝穴を設け、この場合の角度は通常90度相当と考えられる。固定ネジに固定片が具備され、固定片の形状はクランク状態に曲げられ回転溝穴に挿入されている。
固定片は製品出荷時には天井の穴の直径より小さく収納されており、機器が装備されたベースを天井に開口したところに押し付け、固定ネジを緩め方向に回転させる、固定片は固定ネジの回転する力を受けるが固定片のクランク形状が回転溝穴に接触して、回転動作を止められ、固定ネジを数回転させると固定片はベースに対して隙間が開く方向に移動する。
In the present invention, a speaker, a surveillance camera, and a wireless antenna device attached to the ceiling have holes in the thin plate ceiling, the size of the hole is about 200 mm in diameter, and the base is provided with each device. The base is provided with a rotation slot having an angle accompanying rotation around a plurality of fixing screws, and the angle in this case is normally considered to be equivalent to 90 degrees. The fixing screw is provided with a fixing piece, and the shape of the fixing piece is bent in a crank state and inserted into the rotation slot.
The fixed piece is stored smaller than the diameter of the hole in the ceiling when the product is shipped, and the base equipped with the equipment is pressed against the opening in the ceiling to rotate the fixing screw in the loosening direction. The fixed piece rotates the fixing screw. Although the force is received, the crank shape of the fixed piece comes into contact with the rotation groove hole, and the rotation operation is stopped. When the fixing screw is rotated several times, the fixed piece moves in a direction in which a gap is opened with respect to the base.

その後、反対方向に固定ネジを回転させると、固定片が固定ネジを中心に回転し、天井の薄板の上に固定片が回りこみ、回転溝穴の壁に当たるまで回転し止まる。この際に固定片が回転移動しない場合には固定片がクランク状になっている端の見えている部分を指で回転させることもできる。この状態が起きにくくする工夫として、ベースと固定片の間に板バネ又はコイルスプリングを入れることでネジ山に接触抵抗を設けて回転を促す役目がある。固定片の回転が止まった位置で固定ネジを同じ方向に回転させていくと、固定片を締め付けることでベース、天井板、固定片が固定される。これを、数箇所ある固定部分で繰り返す。   Thereafter, when the fixing screw is rotated in the opposite direction, the fixing piece rotates around the fixing screw, and the fixing piece wraps around the thin plate of the ceiling and stops rotating until it hits the wall of the rotation slot. In this case, if the fixed piece does not rotate, the part where the fixed piece is in a crank shape can be rotated with a finger. As a device for making this state difficult to occur, a leaf spring or a coil spring is inserted between the base and the fixed piece to provide a contact resistance to the screw thread to promote rotation. When the fixing screw is rotated in the same direction at the position where the rotation of the fixing piece stops, the base, the ceiling plate, and the fixing piece are fixed by tightening the fixing piece. This is repeated at several fixed parts.

ベースを固定して固定片が確実に定位置にあることを、固定片のクランク状態に曲げられた端が、回転溝穴から露出している部分で位置を目視確認できるようにしてある。   The base is fixed so that the fixed piece is surely in place, and the position of the end of the fixed piece bent in the crank state can be visually confirmed at the portion exposed from the rotation groove hole.

本発明のスピーカ、監視カメラ、無線アンテナ装置などの穴開き天井固定装置は薄板天井に穴を加工後に出荷時の形態でネジを回すドライバーを1本でベースの固定ネジを左回転、右回転する操作で装置を天井に固定する事ができる。且つ、装置が確実に指定位置で固定されていることが、ベースの回転溝穴から、固定片がクランク状の一部が目視確認でき、もしも、指定位置から外れている場合は、固定ネジを緩め、指で固定片のクランク状の一部を指定位置に回し、固定ネジで再度固定する事ができ、施工ミスによる落下の危険性を排除できる効果がある。   The perforated ceiling fixing device such as the speaker, the surveillance camera, and the wireless antenna device of the present invention rotates the base fixing screw counterclockwise and right by using a single screwdriver to turn the screw in the form at the time of shipment after processing the hole in the thin plate ceiling The device can be fixed to the ceiling by operation. In addition, it can be confirmed that the device is securely fixed at the specified position from the rotating groove hole of the base, and a part of the crank shape can be visually confirmed. You can loosen, turn the crank-shaped part of the fixed piece with your finger to the specified position, and fix it again with the fixing screw, which has the effect of eliminating the risk of dropping due to construction errors.
