Abstract

<P>PROBLEM TO BE SOLVED: To provide binoculars easily held and made light in weight and good in handleability of a rotating knob by solving problems of the known binoculars, that a joint part for adjusting a distance between right and left eyes has structure for adjusting a focus while connecting both lens barrels in the joint part; whereby the joint part having large volume is required; consequently the binoculars can not help getting heavier in weight and also they are kept in an interposed state when they are held with one hand or both hands because the joint part becomes a hindrance; furthermore the binoculars are obliged to be unnaturally kept when they are used because four fingers can not be freely held in a space part related to the size of the entire binoculars even in the binoculars where two joint parts are prepared to be separated to positions near to both ends of the lens barrel so that a middle part may be a space. <P>SOLUTION: A joint device for adjusting a distance between eyes in the binoculars, and a focus adjusting device are installed at the upper part in an axial direction, whereby the binoculars are made light in weight, and also can be kept so that they are covered with palm and fingers, so that the binoculars very easily held and easily operated are obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、二つの鏡筒を有する双眼鏡であって、眼間の距離を調整する関節があり、同軸上に焦点調整を行う回転ノブを有し、回転ノブの回転により、左右焦点調整用レンズが軸方向に移動する焦点合せ手段を有する双眼鏡に関する。   The present invention is a binocular having two lens barrels, which has a joint for adjusting the distance between the eyes, has a rotation knob for adjusting the focus on the same axis, and a lens for adjusting the left and right focus by rotating the rotation knob. The present invention relates to binoculars having focusing means that moves in the axial direction.

公知の双眼鏡においては、左右の眼間を調整する為の関節部は両鏡筒を継げながら焦点調整をする為の構造を関節部内に作られていた。その為、大きな体積の関節部が必要となり、両鏡筒の長さの約１／２位の長さになるのが普通であった。その為、双眼鏡の重量としても、より重くならざるを得ず、又、双眼鏡を片手又は両手で持った時、関節部が邪魔になり、双眼鏡をはさむ形で保持する事となる。又、関節部を鏡筒の両端部に近い位置まで離して、２箇所用意し、中間部が空間になるよう考えられた物もあるが、これにしても、双眼鏡の全体の大きさ関係から、４本の指が自由に空間部に収まる事はできないので、どうしても使用時に不自然な保持を余儀なくされる事となる。   In the known binoculars, the joint part for adjusting the distance between the left and right eyes has a structure for adjusting the focus while connecting both lens barrels. For this reason, a large volume joint is required, and the length is usually about ½ of the length of both lens barrels. For this reason, the weight of the binoculars must be heavier, and when the binoculars are held with one or both hands, the joint part becomes an obstacle and the binoculars are held in a sandwiched form. In addition, there are some parts where the joint part is separated to a position close to both ends of the lens barrel and two places are prepared, and the middle part becomes a space. Since four fingers cannot freely fit in the space, they are inevitably held unnaturally during use.

１つの回転ノブで、焦点調整、視度調整を行うタイプの物は、公知の物の中にも見受けられるが、非常に複雑な構造である為、問題も多かった。   A type that performs focus adjustment and diopter adjustment with a single rotary knob can be seen among known ones, but it has a very complicated structure and has many problems.

本発明の課題は、持ち易く軽くて回転ノブの使い勝手の良い双眼鏡を提供する事である。   An object of the present invention is to provide binoculars that are easy to hold, light and easy to use.

本発明における請求項１に特徴付けられた眼間を調整するための関節部を、焦点調整に必要な縦方向の動き量に見合った最短の長さにして、更に上方（接眼側）に寄せた位置に、1ヶ所のみ設置することにより、中心部より対物側の大きなスペースが鏡筒のみになる為、双眼鏡使用時に保持する時、手全体で包み込むように鏡筒を持つ事ができる為、非常に安定した形で、又、違和感の無い保持が可能になる。又、重量的にも軽くする事が可能である。   In the present invention, the joint part for adjusting the interocular space characterized in claim 1 is made the shortest length corresponding to the amount of movement in the vertical direction necessary for focus adjustment, and further moved upward (to the eyepiece side). By installing only one location at a certain position, the large space on the objective side from the center is only the lens barrel, so when holding it when using binoculars, you can hold the lens barrel so that it wraps with your entire hand, It can be held in a very stable form and without a sense of incongruity. It is also possible to reduce the weight.

眼間を調整する為の関節部は、接眼側に偏った位置に構成され、なお且つ、短く小さく設定されている為、二つの鏡筒の間には、大きなスペースが発生し、双眼鏡を保持する時、掌と指で完全に包み込むことができる。又、回転ノブは1つであり、使用者が使用者個人の特徴である左右の眼の視力の違いを補正する必要があるが、この場合、回転ノブを上方に引き上げる事により、回転ノブ回転時に片側のみ焦点調整のためのレンズが移動し、左右の視力差を補正する。   The joint for adjusting the distance between the eyes is configured at a position biased toward the eyepiece, and is set to be short and small, so that a large space is generated between the two lens barrels and the binoculars are held. When you do, you can completely wrap it with your palms and fingers. Also, there is only one rotary knob, and it is necessary for the user to correct the difference in visual acuity between the left and right eyes, which is a feature of the individual user. In this case, the rotary knob can be rotated by pulling the rotary knob upward. Sometimes the lens for focus adjustment moves only on one side, and corrects the visual acuity difference between the left and right.

回転ノブを押し下げる事により、回転ノブの回転はリード環を介して、左右の連結板を通じて、焦点調整レンズは左右同時に同量移動するので、左右同時の中繰り調整が可能になる。   By depressing the rotary knob, the rotation of the rotary knob moves through the lead ring and through the left and right connecting plates, and the focus adjustment lens moves by the same amount at the same time on the left and right.

図１に示すように、関節（２）は、管部材（１．１´）の中間に位置し、且つ上方に設置されている。又、関節（２）の同軸上に回転ノブ（４）が設置されており、回転ノブ（４）の回転により、連結板（３）が上下するよう、図２に示すような構造になっている。連結板（３）には焦点調整レンズが含有されている。   As shown in FIG. 1, the joint (2) is located in the middle of the pipe member (1.1 ′) and is installed above. Moreover, the rotation knob (4) is installed on the same axis as the joint (2), and the connection plate (3) is moved up and down by the rotation of the rotation knob (4). Yes. The connecting plate (3) contains a focus adjustment lens.

中繰り焦点調整（左右同時焦点調整）を図２に添って説明する。
回転ノブ（４）を回転すると、リード軸（５）が回転し、リード環（６）が上下に移動する。リード環（６）の両端には、連結板（３と７）が嵌合されている為、連結板（３と７）も上下に移動する。連結板（３と７）には焦点調整レンズ（８）が含有されているので、焦点の調整が行われる。 The middle focus adjustment (right and left simultaneous focus adjustment) will be described with reference to FIG.
When the rotary knob (4) is rotated, the lead shaft (5) rotates and the lead ring (6) moves up and down. Since the connecting plates (3 and 7) are fitted to both ends of the lead ring (6), the connecting plates (3 and 7) also move up and down. Since the focus adjustment lens (8) is contained in the connecting plates (3 and 7), the focus is adjusted.

縦筋目ローレット（９）、縦筋目ローレット（１０）は回転力を伝える為の縦筋目ローレットである。前記〔０００９〕作動時には縦筋目ローレット（９）は嵌合されており、縦筋目ローレット（１０）は離れている。又、押え環（１１）は、リード軸（５）が回転方向以外には動かないよう位置を決める為の押え環である。   The vertical line knurling (9) and the vertical line knurling (10) are vertical knurling lines for transmitting rotational force. During the operation, the longitudinal knurling (9) is fitted and the longitudinal knurling (10) is separated. The presser ring (11) is a presser ring for determining the position so that the lead shaft (5) does not move except in the rotation direction.

使用者の左右の視力差を補正する為の視度調整に付いて図３にて説明する。
回転ノブ（４）を図のように上方に引き上げる。その時、縦筋目ローレット（９）ははずれ、縦筋目ローレット（１０）が嵌合する。回転ノブ（４）を回転すると視度リング（１２）も回転する。この視度リング（１２）の内壁部には、ギア（１３）が設けられており、そのギア（１３）は回転歯車（１４）と嵌合している。従って視度リング（１２）の回転により、回転ギア（１４）も回転する事となる。回転ギア（１４）にはリードネジ（１５）が設けられており、連結板（３）との間で嵌合している。回転ギア（１４）の回転は、リードネジ（１５）の働きにより連結板（３）の上下動を生む。 The diopter adjustment for correcting the left / right visual acuity difference of the user will be described with reference to FIG.
Pull up the rotary knob (4) as shown. At that time, the vertical knurled line (9) comes off and the vertical line knurled line (10) is fitted. When the rotary knob (4) is rotated, the diopter ring (12) is also rotated. A gear (13) is provided on the inner wall portion of the diopter ring (12), and the gear (13) is engaged with the rotating gear (14). Accordingly, the rotation gear (14) is also rotated by the rotation of the diopter ring (12). The rotating gear (14) is provided with a lead screw (15) and is fitted between the connecting plate (3). The rotation of the rotating gear (14) causes the connecting plate (3) to move up and down by the action of the lead screw (15).

上記〔００１１〕の動きでは、リード環（６）は動かないので、連結板（７）も又動かない事となり、連結板（３）のみが上下動し、片側のみの焦点調整レンズ（８）の動きになるので、使用者の左右の視力差を補正する事ができる。尚、この動作の中では、縦筋目ローレット（９）は離れて、縦筋目ローレット（１０）は嵌合している。   In the movement of [0011], since the lead ring (6) does not move, the connecting plate (7) also does not move, and only the connecting plate (3) moves up and down, and the focus adjusting lens (8) only on one side. Therefore, it is possible to correct the difference in visual acuity between the left and right sides of the user. In this operation, the longitudinal knurling (9) is separated and the longitudinal knurling (10) is fitted.
