<P>PROBLEM TO BE SOLVED: To provide an optical observation assisting device solving a problem in which when an object is viewed by adjusting binoculars mounted on, for example, a tripod to an elevation angle above the horizontal, it is hard to take a look through the oculars of the binocular provided on the upright tripod in a half-sitting posture and the face touches the upper part of the tripod to cause trouble in observation etc. <P>SOLUTION: A fine rack gear 2 is formed on a curved internal surface of an arch-shaped mast 1 and a gear 5 formed on an elevation angle adjusting dial 4 is engaged with the rack gear 2 or the curved internal surface of the arch-shaped mast 1 and an external surface atop of the elevation angle adjusting dial 4 are brought into close contact with each other, and the arch-shaped mast 1 is provided with a U-shaped arm 7 in a slidable state having one end held by a bracket 3 through a ratchet 8 formed on the bracket 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

Industrial application fields

  This invention is a camera. telescope. The present invention relates to an optical observation auxiliary device for mounting optical equipment such as binoculars.

  Conventionally, camera. telescope. When using an optical device such as binoculars, a tripod is used. In these cases, for example, taking binoculars as an example, when looking at an object by raising the binoculars mounted on a tripod to an elevation angle above horizontal, the eyepieces of binoculars mounted on the upright pole of the tripod should be It was painful to look through for a long time, and when the elevation angle was extremely upward, the face hit the upper part of the tripod, which sometimes hindered observation.

Problems to be solved by the invention

  The present invention was shot using a conventional tripod as described above. Provided is an optical observation auxiliary device capable of solving the disadvantages that occur when performing observation or the like.

Means for solving the problem

  This means that a delicate rack gear is engraved on the curved inner surface of the arched mast, and the gear engraved on the elevation adjustment dial is engaged with the rack gear, or the curved inner surface of the arched mast and the elevation adjustment dial The camera has a U-shaped arm that is slidably provided on the arched mast through a ratchet engraved on the bracket, with one end held by the bracket. telescope. The problem can be solved by providing an optical observation auxiliary device on which an optical device such as binoculars is mounted.

  An embodiment of claim 1 of the present invention will be described with reference to the drawings. A delicate rack gear 2 is engraved on the curved inner surface of the arched mast 1, the gear 5 engraved on the elevation adjustment dial 4 is engaged with the rack gear 2, and the bracket 3 is engraved on the arched mast 1. A camera which is provided with a U-shaped arm 7 which is held at one end by a bracket 3 via a ratchet 8 so as to be slidable. telescope. This is an optical observation auxiliary device on which optical equipment such as binoculars is mounted.

  One end of the U-shaped arm 7 is held by the bracket 3, and the other end is provided with a clamp 9 that clamps the central part of the binoculars. The clamp 9 holding the central part of the binoculars is fastened by a fixing bolt 10.

  A delicate rack gear 2 is engraved on the curved inner surface of the arch-shaped mast 1, and this rack gear 2 meshes with a gear 5 engraved on the elevation adjustment dial 4.

  The elevation angle adjustment dial 4 is connected to the bracket 3 together with the U-shaped arm 7 by a pin 13, and both gears engaged by the rotation of the elevation angle adjustment dial 4 act, and the bracket 3 moves up and down the arched mast 1. To do. Two guide rollers 6 are rotatably provided at both ends of the bracket 3 to support the outer surface of the arched mast 1. Further, a ratchet 8 is engraved on the bracket 3, and one end of the U-shaped arm 7 is slidably held through the ratchet 8.

  The lower part of the arch-shaped mast 1 is fixed to the bracket 11 of the arch-shaped mast, and the bracket 11 of the arch-shaped mast is screwed to the horizontal rotating portion 12. The center of the bottom of the horizontal rotating portion 12 is threaded in a concave shape and can be screwed with the bolt on the top of the tripod.

  The present embodiment shows a state in which binoculars are placed, but when a camera is placed,

If the camera adapter 14 as shown in FIG. 4 is sandwiched between the clamp 9 described above, it can be screwed into a concave thread on the bottom of the camera.

  Further, according to the second aspect, the bracket 3 holding the U-shaped arm 7 is formed in an arch-like shape by closely contacting the curved inner surface of the arch-like mast 1 and the outer surface of the tip end portion of the elevation adjustment dial 4. The mast 1 is moved up and down by friction drive.

The invention's effect

  As described above, the present invention is characterized by an arched mast, and the shape of the arch is a photograph. Camera for astronomical observation. binoculars. This is an arch that approximates the curve of the head and face of a user such as a telescope, and when the binoculars are placed on the clamp of the U-shaped arm of the embodiment of the present invention and observation is performed, the elevation adjustment dial is rotated. The binoculars simply move up and down in the form of an arch along the curve of the observer's head and face (see Figure 5). Approach the face to the top. It is very comfortable and effective for observation without contact.
