Description
【０００１】[0001]
本考案は小型から大型カメラに装着出来るうえ殆どの交換レンズに対応し簡単 に且つ効果的に太陽光線を遮断できる角度自在のレンズフードに関するものであ る。 The present invention relates to an angle-free lens hood that can be attached to a small to large camera and can easily and effectively block the sun rays for most interchangeable lenses.
【０００２】[0002]
従来のレンズフードは一般にレンズの先端に丸い筒状のレンズフードを利用し ているため太陽光方向にカメラを向けて撮影する際レンズを通してフイルム面で は長四角状の画像を必要とするため丸いレンズフードでは四隅から悪影響を及ぼ す光が入り効果的なレンズフードとしては不十分であった。又最近はズームレン ズ等の普及もあり各焦点レンズを移動する度レンズフードの長さを調整する必要 もありレンズの先端に取り付けるレンズフードでは太陽光線の余分な光線を完全 に遮断することは不可能であった。又大型カメラにはレンズの先端部分に取り付 け可能な角形の蛇腹式レンズフードがあるが高価で重く長さにも制約がある等利 用し難い欠点があった。 Conventional lens hoods generally use a round cylindrical lens hood at the end of the lens, so when shooting with the camera facing the sunlight, a long rectangular image is required on the film surface through the lens when shooting. The lens hood was not effective as an effective lens hood because light from four corners had an adverse effect. In recent years, with the widespread use of zoom lenses and the like, it is necessary to adjust the length of the lens hood each time each focal lens is moved, and it is not possible for the lens hood attached to the end of the lens to completely block the extra rays of sunlight. It was possible. In addition, large cameras have a square bellows-type lens hood that can be attached to the tip of the lens, but have the drawback that they are difficult to use because they are expensive, heavy, and have a limited length.
【０００３】[0003]
従来の技術で述べた如く丸形の筒状のレンズフードでは四隅から進入する余分 な光を全て防ぐことは不可能であった。又角形のレンズフードは丸形より効果的 とされてきたがレンズの交換の度に長さの違うものを用意しなければならないの で面倒である等の問題があり課題であった。本考案の角度自在のレンズフードは 殆どのカメラに簡単に取り付け出来るうえあらゆる交換レンズに効果的に対応で き且つ自在に角度を調整出来る角度自在のレンズフードを提供するものである。 As described in the prior art, it was impossible to prevent all extra light entering from four corners with a round cylindrical lens hood. Square lens hoods have been more effective than round lens hoods, but they have to be provided with different lengths each time the lens is replaced, which is problematic because it is troublesome. The angle-free lens hood of the present invention provides an angle-free lens hood that can be easily attached to most cameras, can effectively cope with all interchangeable lenses, and can adjust the angle freely.

上記目的を解決する為の手段としてカメラ上部に設けられているストロボ差込 口にネジを有したレンズフード取り付け板を差込み、レンズ方向に移動可能なブ ラケットを挿入させ締め込みナットで締付け、ブラケットの先端に取り付けた自 在クランプ部に板状の遮光板を挟み固定させる。太陽光線の光がレンズに入らな いようカメラのファインダーで確認しながら自在クランプ部の一方に固定されて いる遮光板を上下左右斜め自在に移動させる手段によって不要な光を遮断できる ように工夫してある。 As a means to solve the above object, insert a lens hood mounting plate with a screw into the strobe insertion port provided at the top of the camera, insert a bracket that can move in the lens direction, tighten with a tightening nut, and bracket A plate-shaped light shielding plate is sandwiched and fixed to the self-clamping part attached to the tip of the. While checking with the viewfinder of the camera that sunlight does not enter the lens, unnecessary light can be blocked by means of moving the light-shielding plate fixed to one side of the free clamp part up, down, left, and right. It is.

考案の実施の形態に付いて図面を参照して説明する如く図１はカメラ１の広角 レンズ２に従来の丸形筒状の広角レンズフード３を取り付けた状態であり太陽４ からの光線５がレンズに入る状態図であり、図２はカメラ１に望遠レンズ２’を 取り付け丸形筒状の望遠レンズフード３’を取り付けた状態で光線５がレンズ２ ’に入る状態を示した図であるが図１，図２何れも太陽光線を効果的に遮断する に至らなかった。 FIG. 1 shows a state in which a conventional circular cylindrical wide-angle lens hood 3 is attached to a wide-angle lens 2 of a camera 1 as described with reference to the drawings. FIG. 2 is a diagram showing a state in which a light beam 5 enters a lens 2 ′ with a telephoto lens 2 ′ attached to a camera 1 and a round cylindrical telephoto lens hood 3 ′ attached. However, neither FIG. 1 nor FIG. 2 resulted in effective blocking of sunlight.
【０００６】 図３は本考案の角度自在のレンズフード１８をカメラ１のストロボ差込口６に 差し込んで取り付け、広角レンズ２を使用したときの例で太陽４が高い位置にあ る時の状態図であり、光線５が遮光板１０によって遮断され広角レンズ２に入ら ないようにした。図４は太陽４が低い位置にある時の状態図であり望遠レンズ２ ’を取り付けた状態でも角度自在のレンズフード１８の遮光板１０を自在に移動 させ光線５が望遠レンズ２’に入らないようにしてある。FIG. 3 shows an example in which the angle-free lens hood 18 of the present invention is inserted into the strobe insertion port 6 of the camera 1 and the wide-angle lens 2 is used, and the sun 4 is at a high position. FIG. 3 is a diagram in which a light beam 5 is blocked by a light shielding plate 10 so as not to enter the wide-angle lens 2. FIG. 4 is a state diagram when the sun 4 is at a low position. Even when the telephoto lens 2 'is attached, the light shielding plate 10 of the lens hood 18 which can be freely angled is freely moved so that the light beam 5 does not enter the telephoto lens 2'. It is like that.
【０００７】 図５はカメラ１に角度自在のレンズフード１８を取り付けた平面図で太陽４の 位置がどの状態にあってもブラケット７に開いた調整穴７’でブラケット７の長 さを調整すると共に有効な位置まで左右に角度をふり効果的な位置で締め込みナ ット８を回して締め付け固定させる。又ブラケット７の先端に取付けた自在クラ ンプ部１１のボール付クリップ１４を自在に操作出来るべくようにしたことで遮 光板１０を上下左右斜め自在に移動させて広角レンズ２に光線５が入らないよう に工夫してある。FIG. 5 is a plan view in which an angleable lens hood 18 is attached to the camera 1 and the length of the bracket 7 is adjusted by an adjustment hole 7 ′ opened in the bracket 7 regardless of the position of the sun 4 in any state. At the same time, swing right and left to the effective position and turn the nut 8 at the effective position to tighten and fix. In addition, since the clip 14 with the ball of the universal clamp portion 11 attached to the tip of the bracket 7 can be freely operated, the light shielding plate 10 can be moved obliquely up, down, left and right so that the light beam 5 does not enter the wide-angle lens 2. It is devised as follows.
【０００８】 図６は角度自在のレンズフード１８の分解図でありカメラ１の上部にあるスト ロボ差込口６にネジを有したレンズフード取り付けネジ１２’の先端に固定した レンズフード取り付け板１２を差し込んで調整穴７’の開いたブラケット７をレ ンズフード取り付けネジ１２’に挿入し締め込みナット８を回してカメラ１に装 着する。又、ブラケット７の先端にボールネジ１３を固着させ複数のボールジョ イント１５と自在継手１６でボール付きクリップ１４をボールネジ１３と結合さ せ遮光板１０を挟み固定させる。FIG. 6 is an exploded view of a lens hood 18 that can be freely angled. The lens hood mounting plate 12 is fixed to a tip of a lens hood mounting screw 12 ′ having a screw at a strobe insertion port 6 at an upper part of the camera 1. Insert the bracket 7 with the adjustment hole 7 ′ into the lens hood mounting screw 12 ′ and turn the tightening nut 8 to mount it on the camera 1. Further, a ball screw 13 is fixed to the tip of the bracket 7, and a clip 14 with a ball is connected to the ball screw 13 by a plurality of ball joints 15 and a universal joint 16, and the light shielding plate 10 is sandwiched and fixed.
【０００９】 又自在クリップ部１１はボールネジ１３と同様複数のボールジョイント１５及 びボール付きクリップ１４のボール状の部分をそれぞれ支点として上下左右斜め 自在に効果的に遮光板１０の角度を変えれるように工夫してある。The free clip portion 11 can effectively change the angle of the light-shielding plate 10 freely and vertically and horizontally using a plurality of ball joints 15 and ball-shaped portions of the ball-mounted clip 14 as fulcrums, similarly to the ball screw 13. It is devised.
【０００１０】 図７は角度自在のレンズフード１８の平面図でブラケット７に開いた調整穴７ ’にレンズフード取り付けネジ１２’を差し込んで締め込みナット８で締め付け 、レンズフード取り付けネジ１２’を支点として調整穴７’でブラケット７の長 さを自由に調整出来るようにしてあると共に円周範囲１７の如く左右自在に角度 を変えるように工夫してある。FIG. 7 is a plan view of the lens hood 18 which can be freely angled. A lens hood mounting screw 12 ′ is inserted into an adjustment hole 7 ′ opened in the bracket 7 and tightened with a tightening nut 8. The length of the bracket 7 can be freely adjusted by the adjustment hole 7 ', and the angle can be freely changed left and right as in the circumferential range 17.
【０００１０】 又ブラケット７の先端に取付けた自在クランプ部１１のボール付きクリップ１ ４に挟んだ遮光板１０は自在クランプ部１１の各ボール状の部分をそれぞれ支点 として円周範囲１７のように左右に角度を変えて移動できるとともに、図８で説 明する如く遮光板１０は自在クランプ部１１の各ボール状の部分をそれぞれ支点 として上下自在に移動できるように工夫してある。Further, the light-shielding plate 10 sandwiched between the clips 14 with balls of the universal clamp 11 attached to the tip of the bracket 7 has the left and right sides as shown in a circumferential range 17 with each ball-shaped portion of the universal clamp 11 as a fulcrum. The light-shielding plate 10 is designed so that it can be moved up and down freely with each ball-shaped portion of the free clamp portion 11 as a fulcrum, as shown in FIG.
本考案の角度自在のレンズフードは上述のとおり構成されており、従来のよう に交換レンズを使用する度に其のレンズに合ったレンズフードを用意する必要も なく殆どのカメラに簡単に取り付けでき且つ太陽光線を上下左右斜め自在に移動 できる遮光板で敏速に遮断できるようになった。又大型カメラに使用した場合で も遮光を素早く遮断できるなどの効果がある。 The angle-free lens hood of the present invention is configured as described above, and can be easily attached to most cameras without having to prepare a lens hood that matches the interchangeable lens every time a conventional lens is used. In addition, it is now possible to quickly block the sun's rays with a light-shielding plate that can move freely up, down, left, and right. In addition, even when used in a large camera, there is an effect that light can be blocked quickly.
