Description

【0001】
【発明の属する技術分野】
本発明は三脚などの頭部に取り付けて写真カメラを任意の向きに設定できるようにしたボールヘッドタイプの自由雲台に関するものである。
【0002】
【従来の技術】
従来、カメラを手持ちすることなく任意の向きに設定した状態で写真撮影を行なう場合には三脚などの安定させた専用具の上に自由雲台をセットし、カメラを取り付けた自由雲台の取付台をカメラと共に傾動させて好みのカメラ向きを設定している。このように、必要に応じて取付台を傾動させてその傾きを維持するために自由雲台は球状連結体を備えていて、その球状連結体に取付台の支脚を連結し、球状連結体への拘束力を調整して球状連結体を動くようにしたり動かないようにしている形式のものがある。
そして、球状連結体を必要に応じて拘束できるようにした構成として、球状連結体の下部に対応する押圧体を必要時に引き降ろし可能な状態でスプリングにより当接させたり(特許文献1参照)、球状連結体の下部に一対のコマ体を配置してコマ体の周面により球状連結体を受け皿を介して支持する対の斜面を形成し、一対のコマ体を通るネジ軸の回転操作によりコマ体を互いに離接させ、斜面が互いに近付くことで球状連結体の固定とケース自体の固定とを行なうようにしたものがある(特許文献2参照)。
さらに、球状連結体の下部に偏心軸を配し、その偏心軸の回転で摺動子を上げて球状連結体を固定するようにしたものもあった(特許文献3参照)

【発明が解決しようとする課題】
ところで、上述した各自由雲台を含めて一般的なボールヘッドタイプの自由雲台では、上記球状連結体から円柱状の支柱が一体に設けられていて、この支柱に写真カメラが取り付けられる。そして、前記支柱はケース体の天部とその天部脇の側部に亘る開口から突出していて、この支柱が前記開口の長手方向に沿って動く球状連結体の傾斜と、支柱を回転中心として球状連結体が回る回転とが行なえ、球状連結体の傾斜と回転とで撮影者が所望するように写真カメラの向きと傾斜が得られるようにしている。
しかしながら、上記自由雲台では、取り付けた写真カメラ自体をある程度以上に深い見下げ状態や高い見上げ状態に維持したまま、写真カメラを雲台中心周りに旋回するように移動させることができない。
さらに、自由雲台では、球状連結体の前記支柱にカメラ取付台を取付固定し、そのカメラ取付台に写真カメラを取り付けるとともに、写真カメラの向きと傾斜とを変えるための手添えとなるパン棒も取り付けるようにすることも可能であるが、上述したと同様に写真カメラを見上げ状態としたままや見下げ状態としたままで雲台中心周りに旋回する方向に写真カメラを移動させようと前記パン棒で操作した場合、球状連結体自体が支柱中心で回転して写真カメラの向きが大きく変化してしまうという問題がある。このようなことから、写真カメラ設置位置近傍の地上面や上空での移動体の移動を追った写真撮影には、自由雲台を利用した写真カメラの向きと傾斜とを調整する操作に手数を要するものとなっていた。
そこで本発明は上記事情に鑑み、見上げ状態や見下げ状態としたまま写真カメラを雲台の中心周りに移動させ易くすることを課題とし、自由雲台を用いた写真カメラの向きと傾斜との設定操作を容易にすることを目的とするものである。
【0005】
【課題を解決するための手段】
本発明は上記課題を考慮してなされたもので、天部内方に球状連結体が配されている外形体に、前記球状連結体が対応する側部に開口された円孔から外形体の天部を経て前記円孔とは反対側に及ぶ回動長孔を設けて、該回動長孔を前記円孔の径より狭幅とし、前記回動長孔を通るカメラ支持用の支脚を前記球状連結体が備え、該支脚は、カメラの傾動時に回動長孔の内側面に摺接する平ガイド面を対向二面に設けた略板状とされ、前記平ガイド面以外の対向二面にそれぞれに、支脚が円孔に位置した支脚回転時に円孔内周面に摺接する曲カイド面が設けられていることを特徴とする自由雲台を提供して、上記課題を解消するものである。
【0006】
【発明の実施の形態】
つぎに本発明を図1から図11に示す実施の形態に基づいて詳細に説明する。
図中1は自由雲台であり、図1から図8は第一の実施の形態を示している。この自由雲台1は、写真カメラなどのカメラを直接取付固定する取付台2とこの取付台2を傾動可能に支持する雲台本体とからなるものである。雲台本体3は三脚の頭部などの取付面に配置される取付座4、外殻である外形体5、球状連結体6、押圧体7、調整体8とから構成されている(図4参照)。
【0007】
図示されているように、外形体5は、取付座4を下面に位置させた下ケース9の上面開口に吊り鐘形状の上ケース10を配置し、下ケース9の上面開口周縁11に断面鉤状とした上ケース10の下部周縁12を摺接可能に係止せたものであり(図5参照)、下ケース9に対して上ケース10が雲台中心周りに回転可能に設けられ、後述するようにこの上ケース10を上方に押し上げる力が所要の力以上に強く作用することで、上ケース10の回転が規制されるようにしている。
上ケース10の天部側内方に上記球状連結体6が回転可能に配置され、この球状連結体6の下方に上記押圧体7を配置している。そして、球状連結体6の球部13に対応する側部に開口された円孔14から上ケース10の天部を経て前記円孔14とは反対側に及ぶ範囲に開放幅を一定にした回動長孔15が設けられ、球状連結体6のねじ部16が円孔14から回動長孔15の他端まで移動できるように球状連結体6が上ケース10の内面と摺接しながら傾斜可能とされ、また、前記ねじ部16が円孔14に位置するときには後述するように球状連結体6自体がねじ部16を通る中心周りに回転できるようにしている。なお、球部13は球体であるため、ねじ部16が回動長孔15にあるときに球状連結体6自体がねじ部16を通る中心周りに回転できるが、本自由雲台1では、後述のようにねじ部16が回動長孔15の範囲に位置しているときには球状連結体6はそのねじ部16を通る中心周りで回転しないものである。
【0008】
球状連結体6とともに上ケース10内に配置される押圧体7はその球状連結体6を上方に押し上げる働きをするものである。図示されているようにこの押圧体7は上ケース10内で上下移動可能に設けられた上体17と下体18とからなり、上体17と下体18との間にスプリング20が配置され、後述するように下体18が支えられた状態の下で上体17が球状連結体6を常時上方に押し上げるように付勢している。そして、上体17の上広がりとしたすり鉢状部19の上縁が球状連結体6の球部13に摺接可能に当接し、前記スプリング20による押し上げ力は、押圧体7が球状連結体6を上方に持ち上げているときに、球状連結体6の回動と上記回転が行なえるように予め調整されていて、また、押圧体7による押し上げが上ケース10を上方に押し上げるようにも作用していることから、同様にスプリング20による押し上げ力で上方に持ち上げているときには、下ケース9との係止関係を保ったまま上ケース10が雲台中心周りに回転できるように設けられている。
【0009】
押圧体7の下体18は上記調整体8に支持されていて、上述のようにスプリング20の押し上げ力のみが作用しているときに球状連結体6の回動と回転、及び上ケース10の回転が行なえる。また、調整体8の動作で下体18が上方に移動し下体18に直接当接できるように設けられており、上体17と下体18とが一体となった状態で球状連結体6を上方に付勢することができる。このときの球状連結体6に加わる押し上げ力が大きく、球状連結体6自体の動きを規制(球状連結体6を不動にする)し、また、上ケース10もその下部周縁12が下ケース9の上面開口周縁11に強く当接して上ケース10が雲台中心周りに回転しないように設けられている。
なお、以下に示すように上記調整体8を逆方向に操作することで、上体17に当接していた下体18が下方に移動し、上記スプリング20による押し上げ力のみが作用している状態に戻る。
【0010】
上記押圧体7を上げ下げ可能に支える調整体8は、上下方向に直交する方向をカム回転中心として回転可能なカム軸21を下ケース9内に位置させ、このカム軸21を上記押圧体7の下ケース9内に臨む下体18の下面に摺接可能に当接させて押圧体7を支持させるようにしたものである。
そして、カム軸21は下ケース9の内部においてカム回転中心の直交方向に偏心した偏心部22を備え(図7参照)、下ケース9の側方に突出している一端に固定したハンドル23を手で回転させることでカム軸21を回転できるようにしている。偏心部22が下方側に位置しているときにはそのカム軸21に乗って接している下体18は上体17から離れていて、上述したようにスプリング20による押し上げ状態の下で球状連結体6の回動と回転が可能であり、上ケース10の回転も可能となる。なお、上ケース10が回転する場合には押圧体7も伴って回転するものであり、下体18はカム軸21に乗った状態のまま回転する。図4は調整体8による緩め操作を行なった状態である。
また、調整体8によって球状連結体6と上ケース10とをそれぞれ不動にする締め操作(即ち、カメラの向きと傾斜とを維持させる場合)は、上記ハンドル23を回して偏心部22を押圧体7側に移動させればよく、偏心部22の持ち上がりによって下体18が上方に移動してこの下体18と上体17とが一体となり(図6参照)、ハンドル23を回し込むことで押圧体7による球状連結体6を不動状態にし、また上ケース10が回転しないようになる。この球状連結体を不動とし上ケースを回転不能としている状態を解除するには、ハンドル23を逆方向に回せばよく、逆方向に回すことで偏心部22が下がって押圧体7の下体18がカム軸21に乗った状態のまま下方に移動し、スプリング20による押し上げ力が働く状態に戻ることになる。
このように、調整体8は、カム軸21の回転による押圧体7の伸縮により球状連結体6への拘束力と上ケース10の回転規制力とを変化させることができる。
【0011】
上記取付台2は、カメラを据え置く板部24にカメラ底のねじ孔に螺合可能なねじ体からなる取付手段25を長孔26に移動可能に配したものであり、さらには支脚27を一体としており、その支脚27を上記球状連結体6のねじ部16にネジ付けにて連結することで球状連結体6が支脚27を備えるようにしている。そして前記支脚27は上記円孔14とこの円孔14の径より狭幅にして設けられた上記回動長孔15とのいずれにも位置することができる形状であって、まず、取付台2の傾動時に回動長孔15の内側面に摺接する平ガイド面28を対向二面に設けた略板状とされ、平ガイド面28を前記回動長孔15の内側面それぞれに接しさせながら移動できるものである。このように支脚27は、回動長孔15にあるときに対向配置の平ガイド面28それぞれが回動長孔15の内側面に接するので、球状連結体6のねじ部中心周りに回転することがない。勿論、球状連結体6もねじ部中心周りには回転しない。そのため、取付台2に取り付けたカメラが見上げや見下げの傾斜状態で、かつ上記調整体8の操作で上ケース10の回転が可能となる状態のときに、雲台中心周りにカメラを動かすようにすれば、支脚27の平ガイド面28から回動長孔15の内側面に力が適正に伝わって、上ケース10が容易に回転するようになり、見上げや見下げ状態を保ったままカメラを旋回移動させることができる。特に取付台2にパン棒29を取り付け、深く見下げたり高く見上げている状態のままでパン棒29でカメラを雲台中心周りに旋回するような操作を行なっても上ケース10が簡単に回転するようになり、球状連結体6のねじ部中心周りでカメラが回転することが防止されて、取付台2の傾動操作も組み合わせながら移動体の動きを追うことが簡単に行なえる。
【0012】
また、支脚27の上記平ガイド面28以外の対向二面それぞれには、この支脚27が円孔14の内側面に対応した曲ガイド面30が設けられ、支脚27が円孔14に位置してその円孔14で回転するときに円孔14の内側面に摺接するように設けられており、円孔14での支脚回転時に取付台2がぶれたりガタ付いたりしないように図られている。なお、円孔14の位置は雲台上下方向に対して直角となる線上にあり、支脚27が円孔14の位置となるようにカメラを倒し込めば、カメラを縦かまえの状態にすることができる(図8参照)。
【0013】
本自由雲台1が備える上記取付台2の板部24はこの取付台2に配置するカメラのカメラ底全体を受けるに十分な広さを有するものである。これによって、取付手段25を移動可能にする長孔26の長さを長くすることができ、カメラ底のねじ孔の位置がカメラ中心からズレた側部にあってもカメラ底の広い領域を板部24上に乗せ置くことができるようになり、よって、取付台2にカメラを安定的に取り付けることができる。
【0014】
図9から図11は実施の形態として第二例を示している。この第二例は、取付台2と球状連結体6と回動長孔15と円孔14の各構成については上述した実施の形態と同じである。そして、この第二例において内部に前記球状連結体6を配している外形体5は縦割りされて一対の半割ケース31を相対させてなるものであり、ボス32とこのボス32が出入り可能なボス穴33とを対応させることで、一対の半割ケース31が離接可能に組み合わされている。
外形体5は一対の半割ケース31の組み合わせによって球状連結体6を支持していて、図11に示すように半割ケース31それぞれには上記球部13を摺接可能に保持する略半円状の保持体34が、その球部13の上部と下部とに対応する高さ位置にして半割ケース31の内面を沿うように設けられており、半割ケース31の組み合わせにて球状連結体6を支持している(図10参照)。そして、後述するように半割ケース31相互のわずかな間隔の調整によって同一高さで相対する保持体34それぞれの球状連結体6に対する押圧力が変化し、その保持体34が挟持する球状連結体6の回動と回転とが可能な状態と球状連結体6を固定する状態とを切り替えることができるものである。勿論、球状連結体6の動きが可能となる状態でも保持体34が球状連結体6から離れることはなく、球状連結体6の動きにガタ付きを生じさせずに各保持体34がある程度のフリクションが生じる状態でこの球状連結体6を支える。
【0015】
また、上記半割ケース31それぞれは下辺から雲台中心に向けて張出してなる略半円状の保持体35も取付座4に対応する状態にして備えていて、三脚の頭部などに取付固定される取付座4の外周周りの溝部36に前記保持体35の内辺部が差し入れられている。一対の前記保持体35も上記保持体34と同じように、一対の半割ケース31の間隔の調整によって、溝部36に深く入っている前記内辺部の溝部36の縦面に対する押圧力が変化するものであり、溝部36への押圧力の増大によって取付座4を強く挟持し、取付座4に対する外形体5の雲台中心周りでの回転が行われないようにし、溝部36に対する押圧力の減少によってその溝部36で保持体35が摺接可能な状態となり外形体4が回転できるように設けられている。この溝部36に対する保持体35は、取付座4に対する外形体5の回転が自由になった時点でも溝部36の縦面から離れることはなく、よって、外形体5の回転時にガタ付きが生じないように設けられ、ある程度のフリクションが生じるように調整されている。
このように第二例では、後述の調整体8にて一対の半割ケース31の相互の対向間隔を変化させて保持体34、35による球状連結体6への拘束力と取付座4への回転規制力(外形体に対する取付座の相対的な回転を規制する力)とを変化させることができるようにしているものである。
【0016】
半割ケース31の間隔の調整は調整体8で行われる。この実施の例における調整体8は、図10に示すように一方の半割ケース31に開口された透孔37にねじ軸38を通して、そのねじ軸38の端部側を前記透孔37周りに当接させるとともに、ねじ軸38のねじ部39を、他方の半割ケース31のねじ孔40にねじ付けて、ねじ軸38の端部に設けたハンドル41の回転操作でそのねじ軸38を回転させ、ねじ軸38の回転により半割ケース体31相互の対向間隔を変化させるようにしたものである。即ち、この調整体8での操作によって保持体34、35による球状連結体6への拘束力と取付座4の回転規制力とが上述のように変化する。なお、図において、42はねじ軸38の抜け防止のビス、43はビス42の取付部分を隠すカバーである。
【0017】
上記各実施の例では、カム軸を備えた調整体による操作で球状連結体の回動、回転を止めるとともに外形体の上ケースの回転を止めることができるようにしたり、半割ケースに亘るねじ軸を備えた調整体による操作で球状連結体の回動、回転と止めるとともに外形体の回転を止めることができるようにしているが、本発明はこれらの実施の形態に限定されるものではない。また、各実施の例の自由雲台ではそれぞれカメラを据え置く広面の取付台を有していて、その取付台に支脚を一体的に配して球状連結体のねじ部に螺着させることで前記支脚が球状連結体に備えられるものとして示したが、本発明はこれら実施の例に限定されないものであって、取付台を有さすに前記球状連結体が備える支脚の突端に直接的に写真カメラなどを取り付ける自由雲台にも本発明は実施できるものである。
【0018】
【発明の効果】
以上説明した本発明では、支脚が回動長孔にあるときに平ガイド面それぞれが回動長孔の内側面に接するので、その支脚が球状連結体のねじ部中心周りに回転することがなく、取り付けたカメラが見上げや見下げの傾斜状態で、球状連結体の回動と回転が可能なときに、雲台中心周りにカメラを動かすようにすれば、支脚の平ガイド面から回動長孔の内側面に力が適正に伝わり、雲台中心周りにカメラを旋回させる移動がが容易に行なえるようになる。よってカメラの傾動操作も組み合わせながら移動体の動きを追う撮影が自由雲台を用いても簡単な操作で行なえるなど、実用性に優れた効果を奏するものである。

[Problems to be solved by the invention]
By the way, in a general ball head type free head including each of the above-mentioned free heads, a columnar column is integrally provided from the spherical coupling body, and a photographic camera is attached to the column. And the said support | pillar protrudes from the opening over the top part of the case body and the side part by the top part, this support | pillar inclines with the spherical connection body which moves along the longitudinal direction of the said opening, and the support | pillar as a rotation center. The rotation of the spherical connector can be performed, and the inclination and rotation of the spherical connector can obtain the orientation and tilt of the photographic camera as desired by the photographer.
However, with the above-mentioned free head, it is not possible to move the photographic camera so as to turn around the center of the head while maintaining the attached photographic camera itself in a deep down state or a high up state to a certain degree or more.
Further, in the free head, a camera mounting base is mounted and fixed on the support of the spherical connecting body, a photo camera is mounted on the camera mounting base, and a pan bar serving as a hand for changing the orientation and inclination of the photo camera. It is also possible to attach the photographic camera in the same direction as described above so as to move the photographic camera in a direction of turning around the center of the camera platform while keeping the photographic camera looking up or looking down. When operated with a rod, there is a problem that the spherical connector itself rotates around the support column and the orientation of the photographic camera changes greatly. For this reason, when photographing a moving object on the ground surface or in the sky near the installation position of the photo camera, it is time-consuming to adjust the orientation and tilt of the photo camera using the free head. It was necessary.
In view of the above circumstances, it is an object of the present invention to make it easy to move a photo camera around the center of a camera platform while looking up or looking down, and to set the direction and inclination of a camera using a free camera platform. The purpose is to facilitate the operation.
[0005]
[Means for Solving the Problems]
The present invention has been made in consideration of the above problems, and has an outer body in which a spherical connector is arranged inside a top portion, and a spherical hole which is opened on a side corresponding to the spherical connector. A rotary elongate hole extending to the opposite side to the circular hole through the portion, making the rotary elongate hole narrower than the diameter of the circular hole, and supporting the camera supporting leg passing through the rotary elongate hole. The spherical connecting body is provided, and the support leg is formed in a substantially plate-like shape with two flat guide surfaces slidingly in contact with the inner side surface of the rotating long hole when the camera is tilted, and is provided on two opposite surfaces other than the flat guide surface. In order to solve the above-described problems, a free pan head is provided, in which a curved guide surface is provided for each of the supporting legs that slides on the inner circumferential surface of the circular hole when the supporting leg is positioned in the circular hole. .
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, the present invention will be described in detail based on the embodiment shown in FIGS.
In the figure, reference numeral 1 denotes a free head, and FIGS. 1 to 8 show a first embodiment. The free head 1 comprises a mounting base 2 for directly mounting and fixing a camera such as a photographic camera, and a head body for supporting the mounting base 2 in a tiltable manner. The camera platform body 3 includes a mounting seat 4 disposed on a mounting surface such as a tripod head, an outer shell 5 as an outer shell, a spherical connector 6, a pressing body 7, and an adjusting body 8 (FIG. 4). reference).
[0007]
As shown in the figure, the external body 5 has a hanging bell-shaped upper case 10 disposed on an upper surface opening of a lower case 9 in which the mounting seat 4 is positioned on a lower surface, and a cross-sectional hook 11 on an upper surface opening periphery 11 of the lower case 9. The lower peripheral edge 12 of the upper case 10 is slidably engaged with the lower case 9 (see FIG. 5). The upper case 10 is provided rotatably around the center of the camera platform with respect to the lower case 9, and will be described later. As described above, the force for pushing the upper case 10 upward acts more strongly than the required force, so that the rotation of the upper case 10 is restricted.
The spherical connector 6 is rotatably disposed inside the top portion of the upper case 10, and the pressing body 7 is disposed below the spherical connector 6. A turn having a constant opening width in a range extending from a circular hole 14 opened on a side portion corresponding to the spherical portion 13 of the spherical connected body 6 to the opposite side to the circular hole 14 through the top portion of the upper case 10. A moving elongated hole 15 is provided, and the spherical connector 6 can be inclined while slidingly contacting the inner surface of the upper case 10 so that the screw portion 16 of the spherical connector 6 can move from the circular hole 14 to the other end of the rotating elongated hole 15. When the screw portion 16 is located in the circular hole 14, the spherical coupling body 6 itself can rotate around the center passing through the screw portion 16 as described later. In addition, since the spherical portion 13 is a sphere, the spherical connector 6 itself can rotate around the center passing through the screw portion 16 when the screw portion 16 is in the rotation elongated hole 15. When the screw portion 16 is located in the range of the rotary elongated hole 15 as in the above, the spherical coupling body 6 does not rotate around the center passing through the screw portion 16.
[0008]
The pressing member 7 arranged in the upper case 10 together with the spherical connector 6 serves to push up the spherical connector 6 upward. As shown in the drawing, the pressing body 7 includes an upper body 17 and a lower body 18 which are provided to be vertically movable within the upper case 10, and a spring 20 is disposed between the upper body 17 and the lower body 18. The upper body 17 urges the spherical connector 6 so as to always push it upward while the lower body 18 is supported. Then, the upper edge of the mortar-shaped portion 19, which is the upper part of the upper body 17, slidably comes into contact with the spherical portion 13 of the spherical coupling body 6. Is adjusted in advance so that the rotation of the spherical coupling body 6 and the above-mentioned rotation can be performed when the upper case 10 is lifted upward, and the pushing up by the pressing body 7 also acts to push up the upper case 10. Therefore, the upper case 10 is provided so as to be able to rotate around the center of the pan head while maintaining the engagement with the lower case 9 while being lifted upward by the pushing force of the spring 20.
[0009]
The lower body 18 of the pressing body 7 is supported by the adjusting body 8, and as described above, when only the pushing force of the spring 20 is acting, the rotation and rotation of the spherical coupling body 6 and the rotation of the upper case 10 are performed. Can be done. Also, the lower body 18 is provided so as to move upward by the operation of the adjusting body 8 and can directly contact the lower body 18, and the spherical connecting body 6 is moved upward in a state where the upper body 17 and the lower body 18 are integrated. Can be energized. At this time, the push-up force applied to the spherical coupling body 6 is large, restricting the movement of the spherical coupling body 6 itself (to make the spherical coupling body 6 immovable), and the lower peripheral edge 12 of the upper case 10 The upper case 10 is provided so as not to rotate around the center of the camera platform by strongly contacting the peripheral edge 11 of the upper surface opening.
By operating the adjusting body 8 in the reverse direction as described below, the lower body 18 which has been in contact with the upper body 17 moves downward, and the state in which only the pushing force by the spring 20 is acting. Return.
[0010]
The adjusting body 8 that supports the pressing body 7 so that the pressing body 7 can be raised and lowered has a cam shaft 21 rotatable about a direction perpendicular to the vertical direction as a cam rotation center in the lower case 9. The pressing body 7 is supported by slidably contacting the lower surface of the lower body 18 facing the lower case 9.
The camshaft 21 has an eccentric portion 22 eccentric in the direction perpendicular to the center of rotation of the cam inside the lower case 9 (see FIG. 7), and a handle 23 fixed to one end protruding to the side of the lower case 9 is manually operated. By rotating the camshaft 21, the camshaft 21 can be rotated. When the eccentric portion 22 is located on the lower side, the lower body 18 that is in contact with the camshaft 21 is separated from the upper body 17 and the spherical coupling body 6 is pushed under the state of being pushed up by the spring 20 as described above. Rotation and rotation are possible, and rotation of the upper case 10 is also possible. When the upper case 10 rotates, the pressing body 7 rotates together with the lower case 18, and the lower body 18 rotates while being on the cam shaft 21. FIG. 4 shows a state in which the loosening operation by the adjusting body 8 has been performed.
Further, in the tightening operation for immobilizing the spherical coupling body 6 and the upper case 10 by the adjusting body 8 (that is, when maintaining the direction and inclination of the camera), the handle 23 is turned to push the eccentric part 22 to the pressing body. 7, the lower body 18 moves upward due to the lifting of the eccentric part 22, and the lower body 18 and the upper body 17 are integrated (see FIG. 6). And the upper case 10 is prevented from rotating. In order to release the state in which the spherical connector is immobilized and the upper case cannot be rotated, the handle 23 may be turned in the opposite direction, and the eccentric part 22 is lowered by turning in the opposite direction, so that the lower body 18 of the pressing body 7 is moved. It moves downward while being on the camshaft 21 and returns to the state where the pushing force by the spring 20 acts.
As described above, the adjusting body 8 can change the restraining force on the spherical connecting body 6 and the rotation restricting force of the upper case 10 by the expansion and contraction of the pressing body 7 due to the rotation of the cam shaft 21.

The mounting base 2 is provided with a mounting means 25 comprising a screw body capable of being screwed into a screw hole at the bottom of the camera movably disposed in a long hole 26 on a plate portion 24 on which the camera is to be mounted. The spherical connection member 6 is provided with the support leg 27 by connecting the support leg 27 to the screw portion 16 of the spherical connection member 6 by screwing. The support leg 27 has such a shape that it can be located in both the circular hole 14 and the rotary elongated hole 15 provided with a width smaller than the diameter of the circular hole 14. The flat guide surface 28 that slides on the inner surface of the elongated slot 15 is provided on the two opposing surfaces when tilted. The flat guide surface 28 contacts the inner surface of the elongated slot 15. It can be moved. As described above, the support leg 27 rotates around the center of the threaded portion of the spherical connector 6 because the flat guide surfaces 28 facing each other come into contact with the inner side surface of the rotary elongate hole 15 when they are in the rotary elongate hole 15. There is no. Of course, the spherical coupling body 6 does not rotate around the center of the screw portion. Therefore, when the camera attached to the mount 2 is in a tilted state of looking up or looking down, and the upper case 10 can be rotated by operating the adjusting body 8, the camera is moved around the center of the pan head. Then, the force is properly transmitted from the flat guide surface 28 of the support leg 27 to the inner surface of the rotary elongated hole 15, so that the upper case 10 can be easily rotated, and the camera can be turned while maintaining a look-up or look-down state. Can be moved. In particular, the upper case 10 can be easily rotated even when the pan bar 29 is attached to the mounting base 2 and the camera is turned around the pan head center with the pan bar 29 while looking deep down or looking up high. As a result, the camera is prevented from rotating around the center of the threaded portion of the spherical coupling body 6, and the movement of the moving body can be easily followed while combining the tilting operation of the mounting base 2.
[0012]
On each of the two opposing surfaces of the support leg 27 other than the flat guide surface 28, a curved guide surface 30 is provided in which the support leg 27 corresponds to the inner side surface of the circular hole 14, and the support leg 27 is located in the circular hole 14. It is provided so as to be in sliding contact with the inner surface of the circular hole 14 when rotating in the circular hole 14, so that the mounting base 2 is not shaken or rattled when the leg is rotated in the circular hole 14. The position of the circular hole 14 is on a line perpendicular to the vertical direction of the camera platform. If the camera is tilted so that the support leg 27 is located at the position of the circular hole 14, the camera can be held vertically. (See FIG. 8).
[0013]
The plate portion 24 of the mounting base 2 provided in the free head 1 has a sufficient size to receive the entire camera bottom of the camera arranged on the mounting base 2. This makes it possible to increase the length of the elongated hole 26 that allows the attachment means 25 to be moved. Even if the position of the screw hole on the camera bottom is on the side shifted from the center of the camera, a wide area on the camera bottom can be removed. The camera can be stably mounted on the portion 24, and thus the camera can be stably mounted on the mounting base 2.
[0014]
9 to 11 show a second example as an embodiment. This second example is the same as the above-described embodiment in terms of the configuration of the mounting base 2, the spherical coupling body 6, the rotary elongated hole 15, and the circular hole 14. In the second example, the external body 5 in which the spherical coupling body 6 is disposed is vertically divided so that a pair of half cases 31 are opposed to each other, and the boss 32 and the boss 32 enter and exit. By associating with the possible boss holes 33, the pair of half cases 31 are detachably combined.
The outer body 5 supports the spherical connecting body 6 by a combination of a pair of half cases 31, and as shown in FIG. 11, a substantially semicircle holding each of the spherical parts 13 slidably in each of the half cases 31. The holding member 34 is provided along the inner surface of the half case 31 at a height position corresponding to the upper and lower portions of the spherical portion 13. 6 (see FIG. 10). Then, as will be described later, by adjusting the slight distance between the half cases 31, the pressing force of each of the opposing holding bodies 34 at the same height against the spherical connection body 6 changes, and the holding body 34 sandwiches the spherical connection bodies. It is possible to switch between a state in which the rotation and rotation of the spherical body 6 are possible and a state in which the spherical coupling body 6 is fixed. Of course, even in a state in which the movement of the spherical connector 6 becomes possible, the holder 34 does not separate from the spherical connector 6, and each holder 34 has a certain amount of friction without rattling the movement of the spherical connector 6. This spherical connection body 6 is supported in a state where the occurrence occurs.
[0015]
Each of the half cases 31 also has a substantially semicircular holding body 35 extending from the lower side toward the center of the camera platform in a state corresponding to the mounting seat 4, and is mounted and fixed to a tripod head or the like. The inner side of the holder 35 is inserted into a groove 36 around the outer periphery of the mounting seat 4 to be mounted. As in the case of the holder 34, the pressing force of the pair of holders 35 against the vertical surface of the inner side groove 36 deeply inserted into the groove 36 changes by adjusting the interval between the pair of half cases 31. By increasing the pressing force on the groove 36, the mounting seat 4 is strongly clamped, so that the outer body 5 is not rotated around the center of the camera platform with respect to the mounting seat 4, and the pressing force on the groove 36 is reduced. With the decrease, the holding body 35 can be brought into sliding contact with the groove 36 so that the outer body 4 can be rotated. The holder 35 for the groove 36 does not separate from the vertical surface of the groove 36 even when the rotation of the outer body 5 with respect to the mounting seat 4 becomes free, so that there is no backlash when the outer body 5 rotates. And is adjusted so that a certain amount of friction occurs.
As described above, in the second example, the opposing distance between the pair of half cases 31 is changed by the adjusting body 8 described later, and the restraining force on the spherical connecting body 6 by the holding bodies 34 and 35 and the mounting force on the mounting seat 4 are changed. The rotation regulating force (the force regulating the relative rotation of the mounting seat with respect to the external body) can be changed.
[0016]
Adjustment of the interval between the half cases 31 is performed by the adjusting body 8. As shown in FIG. 10, the adjusting body 8 in this embodiment passes a screw shaft 38 through a through hole 37 opened in one half case 31, and places the end of the screw shaft 38 around the through hole 37. At the same time, the screw portion 39 of the screw shaft 38 is screwed into the screw hole 40 of the other half case 31, and the screw shaft 38 is rotated by rotating the handle 41 provided at the end of the screw shaft 38. The rotation of the screw shaft 38 changes the distance between the half case bodies 31 facing each other. That is, the operation of the adjusting body 8 changes the restraining force of the holding bodies 34 and 35 on the spherical coupling body 6 and the rotation restricting force of the mounting seat 4 as described above. In the drawing, reference numeral 42 denotes a screw for preventing the screw shaft 38 from coming off, and reference numeral 43 denotes a cover for hiding the mounting portion of the screw 42.
[0017]
In each of the above embodiments, the rotation and rotation of the spherical coupling body can be stopped and the rotation of the upper case can be stopped by the operation of the adjusting body provided with the cam shaft, or the screw extending over the half case can be used. Although the rotation and rotation of the spherical coupling body and the rotation of the external body can be stopped by the operation of the adjusting body having the shaft, the present invention is not limited to these embodiments. . Further, the free pan head of each embodiment has a wide mounting base on which the camera is installed, and the supporting base is integrally disposed on the mounting base and screwed to the screw portion of the spherical coupling body. Although the support legs are shown as being provided on the spherical connection body, the present invention is not limited to these embodiments, and a photographic camera is directly provided on the protruding end of the support legs provided on the spherical connection body having a mounting base. The present invention can also be implemented on a free pan head to which a component such as is attached.
[0018]
【The invention's effect】
