Description

本発明は、写真、ビデオ撮影用の三脚に使用するものである。 The present invention is used for a tripod for taking pictures and videos.

従来の大型三脚は移動の少ない屋内での撮影、屋外での使用では据えやすく搬入にも障害が無い場所などに限定され、気軽に携行して撮影に出かけられるような代物ではない。それは一般三脚に比べ重量が数倍あり収納のため縮めても１ｍ近い長さであるからだ。また実際の撮影となると撮影者は脚立など別途足代を用意しカメラの撮影画面の確認をしなければならず、屋外での撮影など頻繁に移動する場合は気軽に利用できない。 Conventional large tripods are limited to places where indoor shooting with little movement and outdoor use are easy to set up and where there are no obstacles to carrying in, and are not a substitute that can be easily taken and taken for shooting. This is because the weight is several times that of a general tripod and the length is close to 1 meter even when retracted for storage. In actual shooting, the photographer must prepare a separate footstep such as a stepladder and check the shooting screen of the camera, and cannot use it easily when moving frequently such as shooting outdoors.

本発明は、大型三脚並みの高さを有し軽量で携行でき、目前の障害物が在ってもその障害物を越えた位置からの撮影を可能とするとともに左右への首振り撮影が簡単にできる三脚を提供することを目的とする。 The present invention is as lightweight as a large tripod and can be carried with light weight. Even if there is an obstacle in front of you, you can shoot from a position beyond the obstacle and easily swing to the left and right. The purpose is to provide a tripod that can be used.

上記課題を解決するため本発明は次のような構成を採用した。
請求項1の発明では、伸縮可能な二本の脚を有する第一の支持台と、上記第一の支持台に回動可能に結合され、伸縮可能な一本の脚を有しカメラを搭載するための第二の支持台を備えた。 In order to solve the above problems, the present invention employs the following configuration.
According to the first aspect of the present invention, a first support base having two extendable legs, and a camera that is rotatably connected to the first support base and has one extendable leg are mounted. A second support base is provided.

請求項2の発明では、脚は支持台に近くなるほど細くなるように構成した。 In the invention of claim 2, the leg is configured to become thinner as it comes closer to the support base.

請求項１の発明によれば、高所からの撮影や障害物が在る場合の撮影において従来の三脚には無い左右への首振り撮影ができることで撮影範囲が広くなることと撮影動作の軽減が図られ創作活動に貢献できる。
カメラはデジタル化によりファインダーを覗かなくても携帯電話、タブレット端末機器のモニター画面で確認できることとピント合わせやシャッターも切れるようになっている。このことから本発明により一般撮影はもとより、高所からの俯瞰撮影あるいは障害物を越えての撮影が可能となる。 According to the first aspect of the present invention, the shooting range can be widened and the shooting operation can be reduced by performing a swinging shooting to the left and right, which is not possible with a conventional tripod, when shooting from a high place or when there is an obstacle. Can contribute to creative activities.
The camera has been digitized so that it can be confirmed on the monitor screen of mobile phones and tablet devices without looking through the viewfinder, and the camera can focus and release the shutter. Therefore, according to the present invention, not only general photography but also overhead photography from a high place or photography over obstacles can be performed.

請求項2の発明によれば、据えた三脚の上部に懸かる重量は脚を細くしたため従来の三脚に比べて軽く、反面足元は重くなり安定性が高まる。このため脚段数を増やしても安定性の高い大型三脚並みの高さを確保できる。また二脚を立て一脚を手で支えて撮影するとき前後への移動操作および左右への画面展開は摩擦抵抗の高い太い脚部を握ることで伝達力が良くなり細やかな操作ができる。 According to the invention of claim 2, the weight hung on the upper part of the installed tripod is lighter than the conventional tripod because the leg is made thinner, while the foot is heavier and the stability is improved. For this reason, even if the number of steps is increased, it is possible to ensure a height equivalent to a large tripod with high stability. Also, when taking a picture with the two legs standing and supporting the one leg by hand, the forward and backward movement operation and the left and right screen development can be performed with a strong transmission force by grasping the thick legs with high frictional resistance.
