【発明の詳細な説明】 本発明は、望遠鏡等を任意の方向に固定し得る（２） 架台、特に球を中心にして俯仰、旋回を自由になし得る
自在球面座架台に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to (2) a pedestal that can fix a telescope or the like in any direction, and particularly to a spherical pedestal that can freely move up, down, and turn around a sphere.

標を視野内に捕えることができない欠点がある。BACKGROUND ART Conventionally, a spherical mount in the form of a camera pan head has been used as a convenient telescope mount, for example, for bird observation. This conventional spherical pedestal is easy to handle because it can fix and release the telescope's rotation and elevation in one operation using only one tightening device. However, this type of spherical pedestal does not have a fine movement device that changes its azimuth and elevation angle.
Also, because it is top-heavy, it has the disadvantage that it cannot be operated freely and accurately capture the target within the field of view with medium-sized or larger telescopes that have high magnification and are relatively heavy.

操作を行うことが困難である。On the other hand, a telescope mount that is widely used for astronomical telescopes and ground-based telescopes and can freely change its orientation and elevation is well known. Some of these ceremonial pedestals are capable of fine movement adjustment, but the rotation and elevation are adjusted using separate fine movement devices, and not only is the structure complicated, but it can also be adjusted in all directions at the same time in one movement. It moves slightly and cannot be fixed. Therefore, with this type of conventional telescope mount, it is difficult to quickly operate the telescope.

いる。The present invention solves the above-mentioned drawbacks of conventional telescope mounts, and provides a flexible spherical mount that is capable of finely adjusting both travel and elevation, and can fix the telescope in its position with a single operation. This is the purpose. For that purpose, in the present invention, a contact member is provided in contact with the spherical surface of the original axis of a spherical seat mount including an original axis and a spherical bearing having a spherical seat in contact with the core sphere axis. A fine adjustment lever device having pressure contact means that presses against the original shaft and a swingable operating lever is provided on the spherical bearing, and the original shaft and the spherical bearing are adjusted to the center of the ball according to the swinging of the operating lever. It is characterized by being configured so that there is relative slight displacement between and (.

要である。Now, the fine adjustment lever 22 of the fine adjustment lever device 20, which is the main part of the present invention, can freely swing around the spherical part 22a as if it were a joystick. Assuming that they are fixed on a spherical surface, the spherical seat outer cylinders 5 and 6 are fixed on the fine adjustment lever 22.
It moves slightly around the original axis 14 in accordance with the swinging of. FIG. 4A is a principle diagram showing the fine movement. The center 01 of the original shaft 14 and the spherical center 02 of the spherical part 22a of the fine adjustment lever 22 are shown in FIG.
The distance from is l. , the spherical center 0° of the spherical part 22a and the slider 2
If the distance from the center 03 of the spherical surface formed on the protrusion 24a of 4 is 11, and the axis of the fine adjustment lever 22 passes through the spherical center 0 of the original shaft 14 as shown in FIG. 4A, then the fine adjustment lever Spherical seat outer cylinder 5 when 22 is swung by 01,
60 rotation amount, ie, spherical θo='J1/71°, so the right side is l. By configuring the telescope to be sufficiently small compared to the above, the telescope can be finely adjusted in both the vertical and horizontal directions. In order to make this fine adjustment effective, the contact piece 25 must be fixed on the spherical surface of the original shaft 14 while the fine adjustment lever is swinging, and the original shaft 14 must be fixed on the spherical surface of the original shaft 14.
It is necessary for the bearing members 16 and 17 to slide lightly on the spherical surface of the bearing.

そのため、原軸１４と軸受は材１６．１７との間（９） の摩擦抵抗Ｆ。と、原軸１４と接触駒２５との間の摩擦
抵抗Ｆ１とは次の如き関係に置かれ々ければ々ら々い、 Ｆ、　　）　　Ｆ。Therefore, the frictional resistance F between the original shaft 14 and the bearing material 16.17 (9). and the frictional resistance F1 between the original shaft 14 and the contact piece 25 may be set in the following relationship: F, ) F.

等しくても差支えない。Therefore, the frictional resistance F2 between the spherical bearing 21 and the spherical portion 22a needs to be greater than the frictional resistance F2 between the aforementioned original shaft 14 and the bridge piece 25. However, as shown in FIG. 4, when the spherical surface of the protruding portion 24a of the slider 24 is located inside the spherical surface of the spherical portion 22a of the fine adjustment lever 22, F2 and Fl may be equal.
