Description

【０００１】
【発明の属する技術分野】
本発明は、グリップを設けたカメラボディに装着され、このカメラボディの光軸と略平行な軸線回りの回転を許容するとともに、三脚を取付可能な取付部を備えるレンズ鏡筒とその取付部材に関するものである。
【０００２】
【従来の技術】
図３は、従来のレンズ鏡筒を三脚に取り付けた状態を概略的に示す側面図である。図４は、従来のレンズ鏡筒を三脚に取り付けた状態を概略的に示す平面図である。
カメラボディ２は、中望遠ズームレンズ鏡筒１を着脱自在に装着している。カメラボディ２には、このカメラボディ２を持ちやすくするとともに、カメラのブレを防止するために、カメラボディ２から突出したグリップ部２ａと、後述する中望遠ズームレンズ鏡筒１のレンズ側マウント部と係合する図示しないカメラボディ側マウント部が形成されている。
【０００３】
中望遠ズームレンズ鏡筒１は、このレンズ鏡筒の先端からカメラボディ２側に向けて、結像面に被写体の像を結ぶ焦点調整を手動操作により行うためのマニュアルフォーカス（ＭＦ）操作環４と、オートフォーカス−マニュアルフォーカス（ＡＦ−ＭＦ）切換環５と、焦点距離を連続的に変えて撮影を行うときに操作されるズーム操作環６と、三脚リング保持部材９と、この三脚リング保持部材９を回転自在に支持する三脚リング７と、絞り環８などから構成されている。
【０００４】
三脚リング７は、カメラボディ２が装着された中望遠ズームレンズ鏡筒１を光軸Ｉと略平行な軸線回りに回転可能とするための部材である。三脚リング７には、中望遠ズームレンズ鏡筒１を三脚３の雲台３ａに固定するための回転式三脚座７ａと、カメラボディ２の撮影姿勢（状態）を決定したあとにねじ込み、中望遠ズームレンズ鏡筒１の回転位置を固定することにより、撮影姿勢を保持するための角度位置設定ノブ７ｂとが設けられている。三脚座７ａは、中望遠ズームレンズのレンズの性格上、三脚取付撮影と手持ち撮影の両方の撮影状態が要求されるために、三脚リング７と一体に設けられている。三脚座７ａは、手持ち撮影時における良好なＭＦ操作性及びズーム操作性を損なうことがないように、ＭＦ操作環４とズーム操作環６との干渉を少なくするように、かつ、これらの操作環の外周と間隔をあけすぎないように配置されている。
【０００５】
図５は、従来のレンズ鏡筒の一部を示す断面図である。図６は、図５のＶＩ−ＶＩ線で切断した状態を示す断面図である。
中望遠ズームレンズ鏡筒１の一部を構成する三脚リング保持部材９の外周部には、切欠部９ａが形成されており、この切欠部９ａは、三脚リング７の内周部に回転自在に嵌め込まれている。このために、中望遠ズームレンズ鏡筒１は、三脚リング７に対して、３６０°回転することができる。
【０００６】
【発明が解決しようとする課題】
しかし、従来のレンズ鏡筒は、中望遠ズームレンズの性格上、三脚取付撮影及び手持ち撮影の両方の撮影を可能とすることが望まれており、手持ち撮影の邪魔とならない程度の大きさの三脚座を中望遠ズームレンズ鏡筒１の後方に取り付ける必要があった。このような構造の従来のレンズ鏡筒により三脚取付撮影を行うときには、カメラボディ２から突出したグリップ２ａと三脚３の雲台３ａとの間隔がどうしても狭くなっていた。このために、カメラボディ２を横位置から縦位置に変更するために、横位置で握っているグリップ２ａを下方まで回転すると、撮影者の手や指が雲台３ａと接触することがあり、光軸Ｉと略平行な軸線回りにカメラボディ２を円滑に回転することができなかった。
【０００７】
本発明の課題は、光軸と略平行な軸線回りにカメラボディを回転しても、撮影者の手や指が三脚の雲台と接触することがなく、カメラボディを円滑に回転することができ、カメラボディの撮影姿勢を容易に変更することができるレンズ鏡筒とその取付部材を提供することである。
【０００８】

【００１４】
【発明の実施の形態】
（第１実施形態）
以下、図面等を参照して、本発明の実施形態について、さらに詳しくに説明する。なお、以下の説明において、従来の技術において説明した部材と同一の部材は、同一の符号を付して説明し、その部分の詳細な説明については省略する。
図１は、本発明の実施形態に係るレンズ鏡筒の一部を示す断面図である。図２は、図１のＩＩ−ＩＩ線で切断した状態を示す断面図である。
【００１５】
三脚リング保持部材９は、レンズ鏡筒の一部を構成するその外周部において、後述する三脚リング７０の内周部を回転摺動が可能なように保持するための部材である。三脚リング保持部材９の外周面には、ピン部材１０がねじ止めされている。
【００１６】
三脚リング７０は、カメラボディ２が装着された中望遠ズームレンズ鏡筒１を光軸Ｉと略平行な軸線回りに所定の角度範囲内において回転可能とするための部材である。三脚リング７０の外周部には、回転式三脚座７０ａと、中望遠ズームレンズ鏡筒１の回転位置を固定するための図示しない角度位置設定ノブなどが設けられている。三脚リング７０の内周部には、後述する逃げ周囲溝７０ｃが形成されている。
【００１７】
逃げ周囲溝７０ｃは、三脚リング７０の内周部の周方向に沿って所定長さ形成された溝である。逃げ周囲溝７０ｃは、三脚リング保持部材９の外周部から突出したピン部材１０を逃げるように形成されており、三脚リング７０とともに回転するピン部材１０が移動可能なように形成されている。逃げ周囲溝７０ｃは、本発明の実施形態においては、図２に示すように、中望遠ズームレンズ鏡筒１が２７０°回転可能なように形成することが好ましい。逃げ周囲溝７０ｃをこの角度範囲内に形成することにより、グリップ２ａを横方向、上方向又は下方向に位置づけることができ、カメラボディ２の撮影姿勢を変えることができる。
【００１８】
回転制限面７０ｄ，７０ｅは、ピン部材１０と当接し、三脚リング７０の回転範囲を規制するストッパ面である。回転制限面７０ｄ，７０ｅは、逃げ周囲溝７０ｃの周方向の両端部に形成されている。回転制限面７０ｄ，７０ｅによる回転規制範囲は、光軸Ｉと略平行な軸線回りにカメラボディ２を回転させたときに、カメラボディ２のグリップ２ａと三脚３の雲台３ａとが近接する範囲に対応して形成されている。本発明の実施形態においては、図２に示すように、中望遠ズームレンズ鏡筒１の回転範囲以外の範囲である９０°に形成することが好ましい。三脚リング７０の回転規制範囲を９０°以下とすると、グリップ２ａを横方向、上方向又は下方向に位置づけるとができる。
【００１９】
次に、本発明の実施形態に係るレンズ鏡筒の動作を説明する。
中望遠ズームレンズ鏡筒１により三脚撮影を行うときには、この中望遠ズームレンズ鏡筒１をカメラボディ２に取り付けた状態で、三脚３の雲台３ａに三脚座７０ａを固定する。図２に示す状態では、カメラボディ２のグリップ２ａは、横方向に位置付けられており、一方の回転制限面７０ｄにピン部材１０が当接することにより、グリップ２ａ下方向へカメラボディ２が回転しないようにしている。図３及び図４に示すように、この状態では、カメラボディ２のグリップ２ａと三脚３の雲台３ａとの間隔は、狭くなっている。このために、グリップ２ａを握った状態において、グリップ２ａの下方向にカメラボディ２を位置づけようとすると、撮影者の手や指が雲台３ａと接触する可能性がある。しかし、ピン部材１０と回転制限面７０ｄとが当接しているために、カメラボディ２のグリップ２ａは、横位置から下方向への回転が規制され、撮影者の手や指が雲台３ａと接触することがない。
【００２０】
図２に示す状態において、図中矢印方向にカメラボディ２を９０°回転すると、カメラボディ２のグリップ２ａは、上方向に位置づけられ、カメラボディ２による縦位置の撮影が可能となる。さらに、図中矢印方向にカメラボディ２を１８０°回転すると、グリップ２ａは、下方向に位置づけられ、カメラボディ２による縦位置の撮影が可能となる。グリップ２ａを握った状態において、以上の動作を行っても、撮影者の手や指が雲台３ａと接触することがない。
【００２１】
本発明の実施形態では、カメラボディ２は、逃げ溝部７０ｃ及び回転制限面７ｄ，７ｅなどの簡単な部品により構成された三脚リング７０により、グリップ２ａの横位置近傍からこのグリップ２ａの下方向への回転が制限されている。したがって、光軸Ｉと略平行な軸線回りにカメラボディ２を回転させても、撮影者の手や指が雲台３ａと接触することがない。また、ピン部材１０、逃げ溝部７０ｃ及び回転制限面７ｄ，７ｅにより、カメラボディ２の回転を規制する角度が９０°以下に制限されている。このために、カメラボディ２は、グリップ２ａの横位置、グリップ２ａの上方向又は下方向の縦位置の状態に撮影姿勢を変更することができ、撮影者の意図どおりの撮影姿勢を従来のレンズ鏡筒と同様に達成することができる。
【００２２】
（他の実施形態）
以上説明した実施形態に限定されることはなく、本発明の技術思想によれば、種々の変形又は変更が可能であり、それらも本発明の均等の範囲内である。
例えば、本発明の実施形態では、中望遠ズームレンズ鏡筒１について説明したが、他のタイプのレンズ鏡筒についても適用することができる。三脚リング７０の回転範囲は、２７０°に限定されず、グリップ２ａを握る撮影者の手や指などと三脚３の雲台３ａとが接触しない範囲であれば、回転範囲は、自由に定めることができる。
【００２３】
本発明の実施形態では、中望遠ズームレンズ鏡筒１を三脚３に取り付けているが、三脚に限らず１脚の支持脚部材であってもよい。また、例えば、カメラボディ自体を支持する部材、被写体を支持する部材又はストロボなどのライティング装置を取り付けるような、三脚以外の部材であってもよい。
三脚リング保持部材９に回転自在に設けられ、逃げ溝部７０ｃ及び回転制限面７ｄ，７ｅなどが形成された三脚リング７０は、本発明の実施形態におけるレンズ鏡筒以外の他のレンズ鏡筒にも取付可能なレンズ鏡筒の取付部材とすることもできる。また、本発明の実施形態では、三脚リング保持部材９側にピン部材１０を取り付けており、三脚リング７０側に逃げ溝部７０ｃを形成しているが、ピン部材１０を三脚リング７０側に形成し、逃げ溝部７０ｃを三脚リング保持部材９側に形成してもよい。
【００２４】
【発明の効果】
以上詳しく説明したように、請求項１又は請求項２記載の発明によれば、カメラボディの光軸と略平行な軸線回りの回転を許容する取付部が回転規制部を含むので、支持脚部材又は撮影補助部材とカメラボディのグリップ部とが近接する範囲での回転を確実に規制することができる。
【００２６】
請求項３記載の発明によれば、リング保持部材の外周部又はリング部材の内周部に凸部を設け、リング保持部材の内周部又はリング部材の外周部に、この凸部と当接するストッパ部を設けたので、リング部材の回転を確実に規制することができる。
【００２７】
請求項４記載の発明によれば、レンズ鏡筒の取付部材は、カメラボディの光軸と略平行な軸線回りの回転を許容する取付部を備え、この取付部は、回転規制部を含むので、このレンズ鏡筒の取付部材を取り付けることにより、カメラボディのグリップ部と撮影補助部材とが近接する範囲での回転を確実に規制することができる。

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. In the following description, the same members as those described in the prior art are described with the same reference numerals, and detailed descriptions of the portions are omitted.
FIG. 1 is a cross-sectional view showing a part of a lens barrel according to an embodiment of the present invention. FIG. 2 is a cross-sectional view showing a state cut along line II-II in FIG.
[0015]
The tripod ring holding member 9 is a member for holding an inner peripheral portion of a tripod ring 70, which will be described later, at the outer peripheral portion constituting a part of the lens barrel so as to be able to rotate and slide. A pin member 10 is screwed to the outer peripheral surface of the tripod ring holding member 9.
[0016]
The tripod ring 70 is a member that enables the middle telephoto zoom lens barrel 1 to which the camera body 2 is mounted to rotate around an axis substantially parallel to the optical axis I within a predetermined angle range. On the outer periphery of the tripod ring 70, there are provided a rotary tripod base 70a, an angle position setting knob (not shown) for fixing the rotation position of the middle telephoto zoom lens barrel 1, and the like. A relief surrounding groove 70c described later is formed in the inner peripheral portion of the tripod ring 70.
[0017]
The escape surrounding groove 70 c is a groove formed with a predetermined length along the circumferential direction of the inner peripheral portion of the tripod ring 70. The escape surrounding groove 70 c is formed so as to escape the pin member 10 protruding from the outer peripheral portion of the tripod ring holding member 9, and is formed so that the pin member 10 rotating together with the tripod ring 70 can move. In the embodiment of the present invention, the escape surrounding groove 70c is preferably formed so that the middle telephoto zoom lens barrel 1 can rotate 270 ° as shown in FIG. By forming the escape circumferential groove 70c within this angular range, the grip 2a can be positioned in the lateral direction, the upward direction, or the downward direction, and the photographing posture of the camera body 2 can be changed.
[0018]
The rotation limiting surfaces 70 d and 70 e are stopper surfaces that abut the pin member 10 and restrict the rotation range of the tripod ring 70. The rotation limiting surfaces 70d and 70e are formed at both ends in the circumferential direction of the escape surrounding groove 70c. The rotation restriction range by the rotation limiting surfaces 70d and 70e is a range in which the grip 2a of the camera body 2 and the pan head 3a of the tripod 3 are close to each other when the camera body 2 is rotated about an axis substantially parallel to the optical axis I. It is formed corresponding to. In the embodiment of the present invention, as shown in FIG. 2, it is preferably formed at 90 ° which is a range other than the rotation range of the medium telephoto zoom lens barrel 1. When the rotation restriction range of the tripod ring 70 is 90 ° or less, the grip 2a can be positioned in the lateral direction, the upward direction, or the downward direction.
[0019]
Next, the operation of the lens barrel according to the embodiment of the present invention will be described.
When taking a tripod with the middle telephoto zoom lens barrel 1, the tripod seat 70 a is fixed to the camera platform 3 a of the tripod 3 with the middle telephoto zoom lens barrel 1 attached to the camera body 2. In the state shown in FIG. 2, the grip 2a of the camera body 2 is positioned in the lateral direction, and the camera body 2 does not rotate downward with respect to the grip 2a when the pin member 10 comes into contact with one rotation limiting surface 70d. I am doing so. As shown in FIGS. 3 and 4, in this state, the distance between the grip 2a of the camera body 2 and the pan head 3a of the tripod 3 is narrow. For this reason, if the camera body 2 is to be positioned below the grip 2a in a state where the grip 2a is gripped, the photographer's hand or finger may come into contact with the pan head 3a. However, since the pin member 10 and the rotation limiting surface 70d are in contact with each other, the grip 2a of the camera body 2 is restricted from rotating from the lateral position to the downward direction, and the photographer's hand or finger is placed on the pan head 3a. There is no contact.
[0020]
In the state shown in FIG. 2, when the camera body 2 is rotated 90 ° in the direction of the arrow in the figure, the grip 2 a of the camera body 2 is positioned upward, and the camera body 2 can shoot in the vertical position. Further, when the camera body 2 is rotated 180 ° in the direction of the arrow in the figure, the grip 2a is positioned downward, and the camera body 2 can shoot in the vertical position. Even if the above operation is performed in the state where the grip 2a is held, the photographer's hand or finger does not come into contact with the pan head 3a.
[0021]
In the embodiment of the present invention, the camera body 2 is moved from the vicinity of the lateral position of the grip 2a to the downward direction of the grip 2a by a tripod ring 70 constituted by simple parts such as the escape groove portion 70c and the rotation limiting surfaces 7d and 7e. The rotation is limited. Therefore, even if the camera body 2 is rotated around an axis substantially parallel to the optical axis I, the photographer's hand or finger does not come into contact with the camera platform 3a. Further, the angle that restricts the rotation of the camera body 2 is limited to 90 ° or less by the pin member 10, the escape groove portion 70c, and the rotation limiting surfaces 7d and 7e. Therefore, the camera body 2 can change the shooting posture to the horizontal position of the grip 2a and the vertical position of the grip 2a upward or downward, and the shooting posture as intended by the photographer can be changed. This can be achieved in the same manner as the lens barrel.
[0022]
(Other embodiments)
It is not limited to embodiment described above, According to the technical idea of this invention, a various deformation | transformation or change is possible, and they are also in the equivalent range of this invention.
For example, in the embodiment of the present invention, the middle telephoto zoom lens barrel 1 has been described, but the present invention can also be applied to other types of lens barrels. The rotation range of the tripod ring 70 is not limited to 270 °, and the rotation range can be freely determined as long as the photographer's hand or finger holding the grip 2a does not come into contact with the pan head 3a of the tripod 3. Can do.
[0023]
