Description

【考案の詳細な説明】〈産業上の利用分野〉本考案は、複数のカメラあるいは測量器等の機
器を支える三脚の改良に関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a tripod that supports equipment such as a plurality of cameras or surveying instruments.

〈従来の技術〉従来のこの種三脚は、三本の支脚が上部で一箇
所に集まつて水平杆の中央を支持し、支持のない
両端へ雲台を介してカメラ等の機器を取付ける構
造であつた。<Prior art> Conventional tripods of this type have a structure in which three supporting legs come together at the top to support the center of the horizontal rod, and devices such as cameras are attached to the unsupported ends via a pan head. It was hot.

〈考案が解決しようとする課題〉しかし、カメラのうち大判カメラには、重さが
数Kgにも及ぶものがある。このため、このように
重量あるカメラを複数台、上記構造の従来の三脚
で支えると、重量のために不安定となり、シヤツ
ター時にブレルという三脚にとつて到命的な欠点
が生ずる虞れがあつた。測量器でも重量あるもの
については、同様である。<The problem that the invention aims to solve> However, among large format cameras, some weigh up to several kilograms. For this reason, if multiple heavy cameras are supported on a conventional tripod with the above structure, the weight will make it unstable, and there is a risk that this will cause a fatal drawback for the Brel tripod when shooting. Ta. The same applies to heavy surveying instruments.

〈課題を解決するための手段〉本考案は、上記の欠点を解消することを目的と
するもので、この目的を達成するために、つぎの
ように構成する。<Means for Solving the Problems> The present invention aims to eliminate the above-mentioned drawbacks, and in order to achieve this purpose, it is configured as follows.

左右方向に延びる水平杆の長手方向にカメラ等
の機器を取付けるスライド溝を設け、この水平杆
の中央と、中央からそれぞれ間隔をおいた両端と
に、水平杆を支える３本の支脚の上端をそれぞれ
枢着してなる三脚。 A slide groove is provided in the longitudinal direction of the horizontal rod that extends in the left-right direction to attach equipment such as a camera, and the upper ends of the three supporting legs that support the horizontal rod are installed at the center of this horizontal rod and at both ends spaced apart from the center. A tripod that is pivoted to each other.

で、伸縮可能とする。<Embodiments> Among the embodiments of the present invention, one for supporting a camera will be illustrated and explained below. 1 is a horizontal rod extending left and right, with brackets 2 provided at both ends and the center;
The upper end of a support leg 3 supporting a horizontal rod 1 is pivotally attached to this bracket 2 with a bolt 4 and a nut. The inclination of the supporting leg 3 can be freely adjusted by loosening the bolt 4. The supporting legs 3 are of a telescopic type with 2 to 3 steps and are extendable and retractable.

に回転させたり、左右・前後へ傾けることができ
る。左右動レバー８は、外側へ出るよう右勝手と
左勝手とをつくる。 A slide groove 5 is provided in the longitudinal direction of the upper surface of the horizontal rod 1, and a pan head 6 is slidably attached to the slide groove 5. Since the pan head 6 is the same as the conventional product, the explanation will be simplified. A mounting bolt (not shown) is provided protruding from the bottom of the pan head 6, and this bolt is passed through the slide groove 5, and its tip is tightened with a nut to fix the pan head 6 to the horizontal rod 1. By loosening the nut, the pan head 6 can be freely moved left and right. The pan head 6 can be freely rotated or tilted left/right/front/back by operating the rotary lever 7, the left/right lever 8, and the front/back lever 9 by loosening them. The left-right lever 8 is made into right-hand and left-hand versions so that it extends outward.

雲台６の数は、左右へ１個づつとは限らないこ
とは、いう迄もない。 It goes without saying that the number of pan heads 6 is not limited to one on each side.

使い方は、従来の三脚と同様である。 It is used in the same way as a conventional tripod.

〈考案の効果〉本考案は以上説明したように、水平杆の左右両

は全くなく、安心して使える製品となつた。<Effects of the invention> As explained above, the present invention has a structure in which both left and right ends and the center of the horizontal rod are supported by supporting legs.
Unlike conventional products that only support the center of the horizontal rod, there is no risk of it shaking even when heavy cameras, surveying instruments, etc. are placed on it, making it a product that can be used with confidence.

なお、この三脚は大判カメラに限らず、普通サ
イズのカメラについても、使えることはいう迄も
ない。 It goes without saying that this tripod can be used not only for large-format cameras, but also for regular-sized cameras.
