JPH01295101A - Maximum diameter measuring instrument for solid sphere - Google Patents

Abstract

PURPOSE:To easily take a measurement by providing two vertical flank plates which are open at a proper angle of intersection, a horizontal support lever which has a scale on the bisector of the angle of intersection on their upper ends, and a vertical measuring plate moving in the rectangular angle to the support lever. CONSTITUTION:The vertical flank plates 1 and 2 are opened at the proper angle alpha of intersection and united by upper and lower reinforcing plates 8 and 8'. The support lever 3 which has the measurement scale 4 is fitted horizontally at the upper ends of the vertical flank plates 1 and 2 while facing the direction of the bisector of the angle alpha of intersection. The support lever 3 is provided with a slide part 6 equipped with a vertical measuring plate 5, which is made movable at right angles to the support lever 3. A finger is inserted into a finger hole 7 to spread the slide part 6, the solid sphere A to be measured is clamped between the vertical flank plates 1 and 2, and the vertical measuring plate 5 is drawn with a spring 9 to read the measurement scale 4. Consequently, the maximum diameter of the sphere is easily found.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention is useful for sorting melons, etc., which are difficult to sort by size. Since it can measure distance accurately and accurately, it is a useful measuring device for sorting the size of melons and packing them into boxes.

(b) Conventional technology Traditionally, when melons, etc. are sorted by size and packaged in 5 to 6 pieces of the same thickness, the circumference is measured with a tape measure or the size is measured by eye. Because we pack all the things in boxes,
It was time-consuming, and the quality was inferior due to irregularities.

(c) Problems to be Solved by the Invention The present invention can easily and accurately measure the maximum diameter of melons, etc. by reading the measurement memory recorded on the support rod, so it is possible to sort the size of melons, etc. This also helps improve quality as it allows for uniform packaging.

(d) Means for Solving the Problems In the present invention, the means for solving the problems will be explained with reference to the drawings. CI) The vertical side plates 1 and 2 are fixed at an appropriate intersecting angle.

(2) A support rod 3 is installed horizontally on the bisector of the intersection angle 1y at the upper ends of the two vertical side plates.

(3) Calculate the measurement memory 4 using the following formula and mark it on the upper surface of the support rod 3.

(4) The vertical measurement plate 5 is provided vertically so as to be able to slide at right angles to the support ring 3, and is connected to the support ring 3 by the slide portion 6 and slid.

(5) Provide a 1ff (ζC finger hole r) at the bottom of the slide portion 6.

(6) Intersecting angle reinforcing plates 8 and 8' are provided at the upper and lower ends of the vertical side plates 1 and 2.

(7) A coiled spring (or rubber string) 9 is provided between the slide portion 6 and the intersection angle reinforcing plate 8.

(Po) Function Since the present invention has the above-described structure, when using it, grasp the end of the support ring 3 with one hand, insert the index finger into the finger hole 7, and press the sliding portion 0 of the measuring plate. Pull your hand 1 ([f] and place the vertical side plates 1 and 2 of the measuring instrument on the sphere A, as if placing it horizontally over the sphere A, and release the index finger of the finger hole. By the action of the spring 9, it will slide. The section 6 slides in all directions, and when the vertical measuring plate 5 comes into contact with the sphere A, the sliding section 6 stops.

By reading the measurement memory at the position where the slide part 0 has stopped, the maximum diameter t of the sphere A can be accurately measured.

(F) Effects of the Invention The present invention enables measurement to be carried out easily and quickly by touching the sphere directly, and more accurately by using a measurement memory with a magnification that is larger than the actual size. ↓Coming.

(G) Other Embodiments In carrying out the present invention, it is possible to turn the measuring instrument upside down and place a sphere on top of it for measurement.

Claims (2)

[Claims] (1) Two vertical side plates opened at an appropriate intersection angle, a support rod is installed horizontally on the bisector of the intersection angle at the upper end, and a measurement memory is attached to the support rod. (2) Provide a vertical measuring plate that slides at right angles to the support rod. The maximum diameter measuring device of a sphere can easily and accurately measure the maximum diameter of a sphere using the measurement memory of the support rod by using the three contact points of the three vertical plates configured as described above.
