Description

[Detailed description of the invention] This invention is a digital display height and sitting height measuring device that incorporates a photosensitive body into a height measuring device, and allows the measurement signal to be expressed on a digital display on a separately prepared counter. It is related to.

Conventionally, such height measuring instruments have a configuration in which a scale plate is attached to the scale unit, and the base and scale unit are integrated in order to maintain the accuracy of measurement values, so it takes a lot of effort when transporting or storing. needed space.

In view of these shortcomings, the present invention allows measured values to be expressed on a digital display, and due to its functional advantages, the main body of the measuring instrument can be mounted on the base at a position that does not interfere with the measurement of the lower part. We have attempted to solve the above drawbacks by providing a detachable structure that can be divided into two scale units and making the insertion operation easy.An example of the implementation of the present invention will be explained below based on the drawings. , 1 is the main body of a body height and sitting height measuring instrument which is measured by a base part 2, a scale unit 3 vertically disposed from the base part 2, and a cursor 4 slidably inserted into the scale unit 3.

The scale unit 3 consists of a rod with an opening in cross section, a cover 5 is fixed to the inside of the scale unit 3 in the longitudinal direction, and a protruding slide guide 6. A slide bracket 7 made of resin is slidably inserted, and a back plate 8 integrally formed with the cursor 4 is fixed to the rear surface of the slide bracket with screws or the like. A bundle 9 for vertical sliding operation is attached.

The base part 2 is composed of a flat plate 10 and a support stand 11 fixed vertically from the rear of the flat plate 10, and an appropriate number of rubber plates 12, 12', etc. are attached to the lower surface of the flat plate 10. Seshime,
In addition, casters 13 are attached to the center of the rear of the flat plate 10, so when transporting the main body 1, the casters 1 can be tilted backwards.
3, it can be moved easily.

A spiral spring 15 is provided inside the support base 11, and the core shaft 14 is rotatably supported on the support base 11. A reflective plate 16 made of a thin material Jt is attached to the end of the spiral spring 15. One end is connected and the other end is pulled out from the upper end surface of the support base 11 and fixed to the slide bracket 7 to which the back plate 8 of the cursor 4 is attached so as to be placed along the cover integral 5 on the rear face of the scale unit 3. As the cursor 4 slides up and down, the reflection plate 16 is forced to be pulled out or wound up.

Incidentally, on the surface of the reflecting plate 16, mirror-like reflecting parts 17 and black absorbing parts 18 are printed at intervals of 2 mm.

Reference numeral 19 denotes a photosensitive body with a built-in optical sensor placed and fixed at a position facing the reflection plate 16 on the upper end surface of the support base 11, and emits light to the reflection part 17 and absorption part 18 of the reflection plate 16. It has the function of sensing the emitted, reflected, refracted, or absorbed light and converting it into an electrical signal.

A counter 20 is removably fitted and supported on a support rod 21 on the upper part of the support stand 11, and has a mechanism capable of digitally displaying signals sensed by the photosensitive body 19.

Next, to explain the mechanism for counting measured values, the counter 20 has a built-in circuit that can convert the signal from the photosensitive body 19 into a digital display.
The photosensitive body 19 is connected to the photosensitive body 19 through a connection cord 22 inserted into the support base 11.

When measuring, first move the cursor 4 from 1 to 1 from the flat plate 10.
The reference point of 1 m is stored by holding the bundle 9 at position m, but since a calibration circuit is built-in, the position of the reference point can be arbitrarily set at any position depending on the situation.

Next, when the cursor 4 is moved so as to come into contact with the head of the person to be measured, the reflector 16 is also pulled out or wound up, and the optical sensor 19 senses this movement and instantly The current measured value can be displayed digitally on the counter 20, and since the counter 20 is detachable, the counter 20 can be placed on a table or other table during measurement, and one person can read the measured value. It can be read and recorded.

Although not shown, if a chair is installed so as to straddle the flat plate 10 of the platform 2, the measurement reference point can be arbitrarily set, so that it can also be used as a sitting height measuring device.

The digital display mechanism may have a reflecting plate 16 and a photosensitive body 19 facing each other, and one of them may be movable, for example, the reflecting plate 1.
6 may be fixed and a mechanism in which the photosensitive body 19 is attached to the cursor 4 may be used.

Next, to explain the fitting and dismounting mechanism of the base part 2 and scale unit 3, there are mounting holes 23 and 23' in the front of the lower part of the scale unit 3.
and openings are formed at the lower end, and elongated holes 24, 24' are formed therethrough, while an opening 25 is formed on the upper surface of the support base 11 through which the scale unit 3 is inserted, and the mounting holes 23, 23' are formed on the front surface. and hole 2 corresponding to the elongated holes 24, 24'
6.26'... is provided through it.

Reference numeral 27 denotes a presser plate having a cross-section with a threaded hole 28, 28', etc., formed at a position corresponding to the hole 26, 26', etc., and which is connected to the scale unit 3. 6, screws 29 and 29' inserted through holes 26 and 26' of the support base 11 are inserted into the lower screw holes 28 and 28.
28', the presser plate 27 is supported such that the protrusion 30 at the lower end abuts the inner wall of the support opening 11 and the upper part is spaced from the inner wall.

Next, the state in which the scale unit 3 is fitted into the support stand 11 will be explained. In the above-mentioned state, the scale unit 3 is fitted in such a way that the front surface of the scale unit 3 is positioned between the inner wall of the support stand 11 and the presser plate 27. , the presser plate 27 has a gap at the upper side with respect to the inner wall of the support base 11, and a guide portion 31 bent outward is formed at the upper end of the presser plate 27, so that the scale unit 3 The scale unit 3 can be inserted by being easily positioned between the inner wall of the support base 11 and the holding plate 27 along the vertical axis, and as the fitting progresses, the holding plate 27 is kept in a vertical position and the scale unit 3 is moved backward. The scale unit 3 is supported by the elongated hole 2 at the bottom of the scale unit 3.
The scale unit 3 can be supported in a fixed position by the upper ends of the scale unit 4 and 24' coming into contact with the screws 29 and 29', and can be firmly fixed by tightening the screws 29'' and 29'' together with the screws 29 and 29'. .

In short, the present invention provides a digital display type height and sitting height measuring device that is equipped with a photosensitive body 19 and a counter 20 that digitally displays the signal from the photosensitive body 19. A long hole 24.24' whose opening extends to the lower end is provided through the base part 2.
The mounting holes 23 and 23' are provided on the front surface of the support base 11, which partially protects the
and holes 26 and 26' at positions corresponding to the elongated holes 24 and 24'.
The holes 26, 26'... are inserted through the holes 26, 26'...
・A cross section approximately 1 having screw holes 28.28'... to be screwed into screws 29.29'... inserted through the
Since the shaped holding plate 27 is provided inside the support stand 11 and the stand part 2 and the scale unit 3 are divided into two parts in a detachable manner, a large amount of space is not required when transporting or storing the scale unit 3.
In addition, when the scale unit 3 is inserted into the base 2 during use, the presser plate 27 can be supported with a gap between the upper part and the inner wall of the support base 11, so that the scale unit 3 can be easily positioned in a fixed position. Its practical effects are enormous.
