Description

[Detailed description of the invention] (Field of industrial application) This invention has an upper main pillar that slides up and down inside the cylinder of a cylindrical lower main pillar whose lower end is fixed perpendicularly to the top surface of the step. A regular scale with the top surface of the step as the O point is inserted into one side of the lower main pillar, and a reverse scale with the maximum scale size of the regular scale scale displayed at the top of each side of the upper main pillar. It concerns a height meter with a scale.

(Prior art) A conventional height gauge is equipped with a scale for measurement on one side of the main column, and the lower surface of the lever of the guide frame that loosely fits on the main column and slides up and down is connected to the main column. The height of the subject was measured by placing it on top of the head of the subject who was standing upright on a step stool on his back, and reading the scale of the corresponding scale.

Also, the utility model registration number by the same applicant as the invention in question
As shown in No. 1612428 (Jikko No. 60-7683), it has a rectangular tube shape with grooves for the main scale on one side of both the left and right sides,
A main pillar with a groove for the subscale scale and a groove for inserting the sliding rod on the other side is installed vertically on the step, and the main scale with the top surface of the step as the O point is inserted into the groove for the main scale. Insert the sub-scale scale into the sub-scale scale concave groove so that the dimension marking part of the same size is located below the display dimension position of the main scale scale, and insert the said sliding rod concave groove into the main column. A floating frame body with a sliding rod that is slidably fitted to the main column and fixed facing downward is inserted so as to be able to move up and down, and a floating frame that is fixed at an arbitrary position on the main pillar is inserted into the outer middle part of the sliding rod. A cursor for reading dimensions is fixed so that the same dimension as indicated by the main scale indicated by the frame is indicated by the subscale scale, and a handle for adjusting the floating frame is protruded below the cursor. There is a height measuring device.

(Problems to be Solved by the Invention) In the height meter according to the above-mentioned conventional technology, the former uses a method in which the lower surface of the lever of the floating frame is brought into contact with the top of the head of the subject who is standing upright on a step with his back to the main column. , the height is measured by reading the size scale of the corresponding scale, but the person taking the measurement must always stand next to the measuring device while taking measurements and recording, which makes it difficult to perform group physical examinations. When it is necessary to measure the heights of a large number of subjects at once, as in the case of Since the handle for lifting and lowering is located at a low position, the person measuring the height can measure and record the height by operating the handle and reading the indicated dimensions on the subscale scale while remaining in a comfortable position on the chair, but it is difficult to measure the height of a short person. This can be difficult due to the sliding rod that becomes an obstacle, and since both measuring instruments are long with a total height of over 2 m, it is extremely difficult to move them when not in use, store them, and pack and transport them during transportation. There were problems such as inconvenience.

(Means for Solving the Problems) The present invention provides a height gauge that solves the above problems, and is capable of sliding up and down within the cylinder of a cylindrical lower main pillar fixed perpendicularly to the top surface of a step stool. Insert the movable upper main pillar, set the regular scale scale on each side of the lower main pillar with the top surface of the step as the O point, and set the upper part of each on both sides of the upper main pillar to the highest value dimension of the regular scale scale. A reverse scale scale with the lower end as the highest measurement value dimension scale is provided so that the upper end display scale line is located at the same height, and the vertical displacement of the fixed measurement frame fitted to the upper end of the upper main column is measured. The height of a tall person is measured by reading the dimensions on the reverse scale scale corresponding to the line of sight provided on both sides of the lower main pillar at a position that matches the highest measurement value scale of the main pillar, and measuring the height of a tall person. This is a height meter that measures the height of a short person by reading the vertical displacement value of a floating measurement frame that is loosely fitted in a detachable manner on the main column using the dimension display value of the regular scale scale of the main column. This will be explained using an example shown in the figures.

The fixed measurement frame 23 is raised and lowered so as to touch the scale reading sight line 1 provided on both sides of the lower main pillar 1.
The height is measured using the display size scales of the reverse scale scales 21 and 22 corresponding to numbers 1 and 15. Also, to measure the height of a short subject, open the cover plate 38 of the floating measuring frame 34 and use the 4 parts of the upper main pillar. , close the cover plate 38 , shift the measuring frame 34 downward, and insert it into the lower main column 1 .
The person to be measured is made to stand upright on the step stool 8a or 8b with his back to the main column, and while holding the floating measurement frame 34, the top of the person's head rests on the top of the head contact surface 32 of the rod portion 33.
The measuring frame 34 moves up and down so as to come in contact with the measuring frame 34, and measures the height by reading the displayed dimension on the regular scale 10 using the lower edge of the floating measuring frame 34.

(Effects) With this invention, the upper main pillar can be raised and lowered by a handle located at a low position, and the measurement dimensions can be read using a reverse scale scale using the scale reading sight lines provided on both sides of the lower main pillar. As a result, the measurer can measure and record the height of a tall subject in a comfortable posture while hanging on a chair, which greatly reduces the measurer's effort and time. Height can be measured easily and reliably by using a floating measurement frame, and since the upper main column can be stored within the lower main column, it is convenient for moving and storing when the height meter is not in use. This has excellent practical effects, such as the use of a foldable step stool, which allows for compact packaging during transportation.
