Description

[Detailed description of the invention] This invention relates to a hand-shaped telescope that is used to determine the height of a grove of trees, etc. by triangulation.

Conventionally, transits have been used to triangulate the height of trees, etc., but they had the disadvantage of being too expensive for children to use as learning materials.

This idea was developed in view of the above circumstances, and its purpose is to provide a hand-held telescope with a simple structure that can triangulate the height of objects to be measured, such as a grove of trees. A gripping handle is provided on the lower side of the telescope body, and this gripping handle is equipped with an angle meter for measuring the angle of elevation and elevation, and a reel-type thread tape measure that determines the horizontal distance using a fixed length of thread. It is something to do.

An embodiment of this invention will be described below with reference to the drawings. In the figure, 1 is a telescope body with a fixed magnification in which an eyepiece (concave lens) 2 and an objective lens (convex lens) 3 are assembled in a lens barrel 4. Standards 5a and 5b are provided on the barrel 4, spaced apart on the eyepiece side and the objective side, and a handle attachment portion 6 is formed on the lower side of the main body lens barrel 4 on the eyepiece side. Note that the standards 5a and 5b may be cross-shaped standards provided within the main body lens barrel 4. Reference numeral 7 denotes a main body gripping handle which is inserted and fixed into the handle attachment part 6 of the main body lens barrel 4 by engaging with a dovetail groove. The gripping handle 7 is made of a plastic molded product, and the inner side surface surrounded by the outer circumferential protruding edge 7a is used to measure the elevation angle α of the object A to be measured (the angle of elevation of the apex of the object to be measured with respect to the horizontal line). A thread tape measure 10 that determines the horizontal distance L between the object to be measured A and the elevation angle measurement position by the length of the thread 9, and an azimuth meter 11 fitted and fixed in the middle thereof are provided. The angle meter 8 has a structure in which when a lock button 12 is pressed, a pointer 14 pointing toward an angle scale 13 rotates downward by gravity. Cap 1 fitted into the protrusion on the back side
The button is urged outward (downward) by a button integral spring 14c so as to engage with the button 4b. The angle scale 13 is displayed on the surface of the transparent cover 15, and the scale is set at 0 degrees on a perpendicular line perpendicular to the center line of the main body lens barrel 4, and the pointer is rotated from this 0 degree position. For example, it is displayed as an angle scale within a 90 degree range in the direction of movement. Therefore, with the pointer 14 set to the 0 degree position in the locked state, hold the main body gripping handle 7 and place the standard 5a, 5b of the telescope main body 1 on the top of the object to be measured A.
When the lock button 12 is pressed and operated, the pointer 14 rotates downward by gravity, and the lock button 1 is pressed.
Since it is locked in that position by releasing the pressure at step 2, the elevation angle α of the object to be measured A can be measured by continuing the rotation range of the pointer 14 on the angle scale 13. In addition, the reference numeral 16 shown in FIGS. 2 and 3 is a handle attachment part of the button spring 14c, 30 is a protrusion plate that guides both sides of the lock button 12, and 31 is a slide engagement part in the long hole 32 of the lock button 12. The matching guide projections are shown. A thread tape measure 10 provided at the tip of the gripping handle 7 has a thread reel 18 that is fitted and locked onto a protruding shaft 17 on the inner surface of the tip of the handle 7, and a thread tape measure 10 that is wound around this reel 18 to form a tip hole 19 of the gripping handle 7. The structure includes a thread 9 pulled out from the thread 9 and a knob 20 attached to the end of the thread. In addition, the tape measure thread 9
is set to a certain length (for example, 5 m), and when the height H of the measured object A is determined by triangulation, the horizontal distance L from the measured object A to the elevation angle measurement position is
It is designed to be determined by a multiple value of the yarn length. Therefore, the horizontal distance L (for example, 20 m) determined by the multiple of the tape measure thread 9, the elevation angle α of the top of the object with respect to the horizontal plane measured by the elevation angle meter 8, and the user's eye height. Accordingly, the height H of the object to be measured A can be easily determined. In addition, 22 in the figure
is an attached magnifying glass that is stored in the opening at the tip of the main body lens barrel 4;
A loupe frame 24 having a U-shaped plane that can close 3a;
The loupe frame 2 is composed of two compound convex lenses 27 and 28 that are fitted into the center opening 24a of the loupe frame and held by lens holders 25 and 26.
The loupe housing 23 is held detachably by elastically engaging the engagement holes 24b provided in both side plate portions of the loupe housing 23 with the inner protrusions 29a of the latching pieces 29 on both sides of the loupe housing 23. This loupe 22 is used by removing it from the tip of the main body lens barrel 4 (loupe storage part 23) when observing insects, small plants, etc. in fields and mountains. It is stored in the opening at the tip of the cylinder 4. Therefore, when the telescope main body 1 is used, it is a matter of course that it is removed from the tip of the main body lens barrel 4.

Since the hand-held telescope for triangulation of this invention is as described above, it is possible to easily triangulate the height of objects to be measured, such as a grove of trees, using the angle meter and thread tape measure attached to the grip handle of the main body. This has the effect that it can be provided at a low cost as a learning material for children and others.
