TECHNICAL FIELD OF THE INVENTION
The present invention can be assembled and disassembled to enable the observer and the observation device to be able to observe various sky with a telescope such as binoculars mounted on a mechanism capable of adjusting the elevation angle, facing the same orientation on the same rotary table. It is a starlit sky observation device and relates to an observatory-mounted eclipse table type astronomical telescope.
[0002]
[Prior art]
There is no commonly used device for observing a celestial body with binoculars while an observer is sitting on a chair. The concept and self-made examples will be published in astronomical magazines, etc., but most will strengthen the back of the swivel chair, extend the arm with the rotating part at the back located on the head of the back to the front of the observer, and attach binoculars to this Most of the devices attach the counterweight of the binocular to the arm on the opposite side of the binocular (see FIG. 8). Generally, when observing an astronomical object with binoculars, the astronomical object is observed by holding the binoculars or attaching the binoculars to a tripod for photography.
[0003]
[Problems to be solved by the invention]
According to the conventional general method, binoculars in which most of the optical systems are almost direct-view type, when observing the binoculars with the binoculars facing the sky, hand-held observation of the binoculars satisfactorily due to fatigue of the arms and shaking of the image due to camera shake. can not see. When observing the celestial body with binoculars attached to a photographic tripod, fatigue and shaking of the arm are resolved, but the binocular eyepiece must be looked up from the bottom of the tripod, and a forced posture is forced. Therefore, it is difficult to observe the celestial body near the zenith with an unreasonable posture and the body is obstructed by a tripod. In addition, the direction in which the body can be observed at the same position is also limited to the front, and when observing a celestial object in the left, right, or rear direction, the position of the body and the direction of the binoculars with respect to the tripod must be significantly changed.
In a device that observes a celestial body with binoculars while an observer of a conventional concept sits on a chair, the behavior of the observer sitting on the chair is easily transmitted to the optical system as vibration because the binoculars are supported by the chair. In addition, the chair is required to have high rigidity in order to suppress the vibration of the optical system which is sensitive to vibration, and the legs of the chair are large and heavy in order to obtain stable horizontal rotation. Therefore, the whole apparatus becomes large and heavy. Further, in the conventional apparatus, there is insufficient consideration to easily match the eyes of the observer with the optical axis of the optical system, maintain an appropriate distance from the eyepiece, and secure an effective visual field.
[0004]
The present invention has been made in view of such a problem, and an object of the present invention is to hold an optical device by a structure to reduce the weight when observing the sky with a relatively low-magnification telescope such as binoculars. Keep your body open and secure a stable field of view, do not force your body to the optical system, and stably observe the sky for a long time without changing your body position other than the angle of the neck to the optical system It is to provide a device which can do it.
[0005]
[Means for solving the problem]
In order to achieve the above object, the present invention obtains a horizontal rotation on a rotary table, mounts an observer on a chair on the rotary table, and attaches a mechanism for controlling the elevation angle of the binoculars to a main support provided on the rotary table. The sky can be observed by adjusting the binoculars to the position of the eyes of the observer.
[0006]
The rotating part was placed at the bottom and horizontal rotation was performed by a rotary table, and a chair supporting the observer and a structure supporting the optical system were separately installed on the rotary table. This makes it difficult for the behavior of the observer sitting on the chair to be transmitted to the optical system as vibration. In addition, the rigidity of the chair itself is no longer required, and in the embodiment, the chair is a folding camping chair.
[0007]
At the top of the chair, a detachable headrest mechanism that also serves as a backrest is provided, and the headrest supports the back of the head, making it easy to determine the position of the binoculars and the head, and when looking into the sky at a high angle, the weight of the head is back In addition, fatigue of the neck can be reduced. The headrest is supported by a compression spring and has a reaction force from above. The headrest can be adjusted up and down to set the optimal occipital position for the observer.
[0008]
The structure supporting the optical system includes a detachable main support installed beside the observer on the rotary table, left and right stays supporting the main support, and front and rear stays. The left and right stays and the front and rear stays connect the upper portion of the main support and the end of the rotary table with an opening angle of about 90 degrees to form a lightweight and strong structure.
[0009]
The main column is cylindrical, with binoculars attached and a mechanism corresponding to the elevation angle. By changing the position of the whole mechanism up and down and fixing it, the height of the observer's eyes and the height of the optical system can be adjusted, and the whole mechanism can be rotated horizontally and fixed. Thus, the position of the observer's eyes and the front and rear of the optical system are adjusted. Further, if the mechanism is moved largely in front of the observer, the observer can easily leave and take a seat.
[0010]
The means to attach binoculars and follow the observer's eyes to changes in elevation angle is to set the peeping surface of the eyepiece on the binocular fixed arm attached to the rotating part at an outer position about 40 mm away from the center of the rotating part The binoculars are fixed to a binocular fixing arm near this position because the movement is similar to the movement of the eyes when the neck is moved up and down.
[0011]
By pulling the weight of the binoculars and the binocular fixing arm upward by a spring, the counterweight and the long arm in the conventional device are not required, and the device can be reduced in size and weight.
[0012]
The rotating table and chair, headrest mechanism, main support, left and right stays, and front and rear stays can be disassembled by loosening the set screws, making it easy to assemble and store, and easy to transport. Can be realized.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. In the above, the chair 21 and the main support 4 are provided on the turntable 3, and the front and rear stays 6 and the right and left stays 8 reinforce the main support 4 from the end of the turntable 3 at an opening angle of about 90 degrees. The binoculars 29 are attached to the binocular fixing arm 17, and the elevation angle is controlled by the rotating unit 14. The rotating part 14 is fixed to the rotating part mounting bracket 13 and connected to the main support 4. The binoculars 29 and the binocular fixing arm 17 are pulled upward by the suspension spring 19 to cancel the gravity thereof. The stop wire 20 prevents excessive downward movement. By applying a rotational resistance to the rotating part 14 and optimizing the tension and the mounting position of the suspension spring 19, the vertical angle of the binoculars 29 can be freely stopped. A headrest 22 is provided on an upper part of the chair 21. The headrest 22 moves up and down along a headrest stay 26, and is fixed to the headrest stay 26 by a headrest fitting 23 via a compression spring 25. The rotary table 3 is mounted on a rotary base 1 via a bearing 2 and is horizontally rotated by the bearing 2.
[0014]
FIG. In the embodiment shown in FIG. 7, the binoculars 29 and the binocular fixing arm 17 are oriented at an elevation angle of about 30 degrees. The angle of elevation is fixed by tightening the rotation fixing screw 15 of the rotation unit 14, and fine adjustment can be performed by the rotation fine movement handle 16. The above-mentioned mechanism is fixed to an arbitrary position on the main support 4 by the rotating part mounting bracket 13. The height of the observer's eyes and the height of the eyepiece of the binoculars 29 are adjusted by the mounting height of the rotating unit mounting bracket 13. The stop ring 12 is for preventing the fall when the set screw 10 of the rotating unit mounting bracket 13 is loosened. When the observer's eyes are aligned with the front and rear positions of the eyepieces of the binoculars 29, FIG. As shown by, when the fixing of the rotating part mounting bracket 13 to the main support 4 is brought close to the observer's eye and fixed, the eyepiece of the binoculars 29 is drawn. On the contrary, FIG. As shown by, when the fixing of the rotating unit mounting bracket 13 to the main support 4 is fixed away from the observer's eye, the eyepiece of the binoculars 29 moves forward. FIG. When the binoculars 29 are largely moved as described above, it is easy to leave the apparatus from the apparatus of the present invention.
[0015]
FIG. In the embodiment shown in FIG. 7, a headrest stay 26 is connected to the upper part of the chair 21 on the left and right, and the headrest fitting 23 is fixed to an arbitrary position above and below the headrest stay 26 with a stay screw 28. The headrest 22 is mounted on the compression spring 25 and moves up and down along the headrest stay 26 by pressure from above. This is shown in FIG. As shown in (2), when the elevation angle of the binoculars 29 is increased, the occipital region of the observer is supported, and the weight of the head is supported. In addition, a backrest is formed together with the headrest cover 27, thereby contributing to a stable posture of the observer. The headrest stay 26 is made of a resilient frame, and is positioned behind the observer, so that the observer can easily sit and take off.
[0016]
FIG. In the embodiment, the positional relationship between the rotating unit 14 and the binoculars 29 attached to the binocular fixed arm 17 is shown. When the center of the binoculars 29 eyepiece is set within the range indicated by oblique lines and the position of the eyes of the observer is optimized, even if the elevation angle of the binoculars 29 is changed to an angle of about 70 degrees from the horizontal, it is possible to look directly.
[0017]
