Description

[Detailed Description of the Invention] This invention relates to a weight scale, and particularly to a weight scale that displays a rank of health condition based on a standard weight determined according to the height of the person being weighed.

Conventionally, as the above-mentioned weight scale, there is one disclosed, for example, in Japanese Utility Model Application Publication No. 52-134366. This is a weight scale in which the rotary scale plate rotates with respect to a fixed pointer, and a height scale is provided along the radial direction along the extension line of the fixed pointer of the rotary scale plate, and the height scale is set on the rotary scale plate to indicate "thin". "standard",
It has a standard weight section that indicates things like "fat". This standard weight section is calculated by converting a graph in which weight is plotted on the X-axis, height when the weight is the standard weight, height when thin, etc. on the Y-axis in Cartesian coordinates, and r is the radiation length, θ is expressed as body weight in polar coordinates (r, θ) format. Of course, the magnitude of r and the height scale are selected to correlate with each other. However, with such a scale,
Since the height scales are provided along the radial direction, the intervals between the height scales are narrow. Also,
Since the standard weight section is provided in polar coordinate format,
They form multiple spirals with relatively narrow intervals. Together, these two factors mean that, for example, if a person whose height is between two height scales uses this scale to find out whether his or her weight is normal or whether he or she is underweight, he or she will not be able to clearly understand whether his or her weight is normal or whether he or she is underweight. The problem was that it was difficult.

The purpose of this invention is to provide a weight scale that solves the above problems.

This invention will be explained below based on two illustrated embodiments. A first embodiment is shown in FIGS. 1 to 4. In each of these figures, 1 is a mounting base, 2 is a main body, 3 is a zero point adjustment knob, 4 is a fixed pointer, 5 is a transparent plate, and 6 is a rotary scale board.

The rotary scale plate 6 is connected to the weighing section, and when a person to be weighed is placed on the platform 1, the rotary scale plate 6 is rotated counterclockwise by an angle proportional to the weight of the person. A weight scale 7 is provided along the periphery of the rotary scale plate 6 so as to increase clockwise from 0 kg to 100 kg,
At the rotated position, the fixed pointer 4 moves to the transparent plate 5.
The weight is displayed on a window 8 provided in the window 8. This configuration is the same as a conventional scale.

Reference numeral 10 denotes an excess/deficiency scale, which is formed of a transparent material into a disk smaller than the rotary scale 6, and arranged coaxially above the rotary scale 6, corresponding to the inner position of the weight scale 7. Calorie increase/decrease scale 12
A height indicator 16 is also formed along the radial direction of the excess/deficiency scale 14. This excess/deficiency scale board 10 has a knob 18
It is pivotally supported by the transparent plate 5 so as to be rotatable.

The excess/deficiency scale 14 is graduated in the same division as the weight scale 7 so as to increase in the counterclockwise direction based on an arbitrary position on the peripheral edge of the excess/deficiency scale plate 10.
Calorie increase/decrease scale 12 means that your weight will decrease by 1 in 90 days.
The calorie intake of 77.8 cal that needs to be reduced per day in order to reduce kg is scaled to correspond to the 1 kg scale of excess/deficit scale 14. An index 19 indicating these scales 12 and 14 is provided at the 32.5 kg scale of the weight scale 7 of the rotation scale 6. The height pointer 16 is provided along the radial direction from the 5 kg position of the excess/deficiency scale 14.

20 is a fixed plate, which is made of an opaque material and has a transparent plate 5
It has a spiral edge 22 whose diameter increases in a clockwise direction, which is fixed to the upper part of the dial 10 and located far inside the over/under scale 14 of the over/under scale dial 10. A height scale 24 is graduated along this edge. This scale method first sets a 130 cm scale at the intersection of the extension line of the fixed pointer 4 and the curved edge 22,
360°/
Multiply by 100Kg to obtain a scale angle of 16.92° between 130cm and 120cm, and the 120cm scale is marked at a position 16.92° apart in the clockwise direction. The others are also scaled in the same way. With this configuration, height guide 16
When the knob 18 is rotated so that it matches the height scale 24 corresponding to the height of the person to be measured, the 0 kg of the excess/deficiency scale 14 and the index 19 are the number of weight scales corresponding to the standard weight corresponding to the set height. When a person to be weighed is placed on the platform 1, the indicator 19 cooperates with the weight scale 6 to display the weight deviation from the standard weight.

Along with the height scale 24, health rank display lines 26 and 28, which are a feature of this invention, are provided on the rotary scale plate 6. This rank display line 26 is provided, for example, as follows. 100, 110, 120, 130, 140,
Arcs 30, 31, 32, 33, 34, and 35 whose radius is the distance to the height scale of 150 are drawn on the rotary scale board 6 with the center of the rotary scale board 6 as the center. And it is 1.2 times the standard weight of 27.2Kg for a height of 130cm.
When the fixed pointer 4 indicates the weight scale of 32.64Kg, the intersection point 3 of the arc 33 and the height scale of 130cm
6 on the rotary scale plate 6. Hereinafter, with the fixed pointer 4 indicating each weight scale corresponding to 1.2 times the standard weight corresponding to the remaining height scales, the height scales and the corresponding arcs 30, 31, 32, 34, 35 are shown below. Take the intersection points 37, 38, 39, 40, and 41. Then, by connecting each of these intersection points, the display line 26 is completed. When the display line 26 is drawn in this way, when a person of a certain height who weighs 1.2 times the standard weight corresponding to that height is placed on the platform 1, the display line 26 and the person's height will be drawn. It always intersects the height scale,
If this person weighs more than 1.2 times the normal weight listed above,
The display line 26 moves to the left of the height scale representing the height of the person, and moves to the right of the height scale representing the height of the person if the person is lighter than 1.2 times the standard weight. The display line 28 is drawn in the same manner as the display line 26 except that the standard weight corresponding to each height scale is multiplied by 1.3, so its explanation will be omitted.
The left side of the display line 26 is colored green, and the display line 2
The area between 6 and 28 is colored yellow, and the right side of the display line 28 is colored red. The method of providing such display lines can also be explained as follows. For example, in the case of the display line 26, each height and the value 1.2 times the corresponding standard weight are plotted on the scale board 6 in polar coordinate format using the 0 point position of the weight scale 7 as a reference, and the plotted points are plotted on the scale of that height scale. This is done by shifting the angle between the scale and the standard 130cm scale, and connecting these shifted points. For example, as shown in Figure 4, if the person is 120cm tall, the standard weight is 22.5Kg, and 1.2 times that is 27Kg. Take the intersection of this 27Kg scale and the 120cm radius 34 (indicated by x in the figure). This shows the height of 120 cm and 1.2 times the standard weight in polar coordinate format. This is the height scale 120cm
The above-mentioned intersection point 39 is obtained by shifting the scale by the angle φ between the scale and the standard 130 cm. Other intersection 36,
37, 38, 40, and 41 are similarly provided, and the display line 26 connects these. Display line 2
8 is provided in the same manner. The display lines 26, 28 provided in this way do not have a spiral shape.

The weight scale thus constructed is used in the following manner. Assuming that the height of the person to be measured is 145 cm, first align the zero scale of the weight scale 7 with the fixed pointer 4 using the zero adjustment knob 3 as shown in Figure 1, and then adjust the height as shown in Figure 3. Knob 18 as shown in
The height guide 16 is set to indicate the height scale 24 of 145 cm. Next, the person to be weighed
When placed on top, the rotary weight scale plate 6 scales and the fixed pointer 4 indicates the weight. The weight is as shown
If the weight is 45.7Kg, indicator 19 is + of excess/deficiency scale 14.
It specifies 9kg. This +9 kg means that the weight is higher than the standard weight of a person with a height of 145 cm. In this state, as mentioned above, the display line 2
6 and 28, the set height of 145 cm is located in the yellow area between display lines 26 and 28, which indicates that the person to be weighed tends to be obese and is in the category of requiring caution. In addition, in the rank display, green means normal, yellow means caution is required, and red means treatment required.

In the second embodiment, as shown in FIGS. 5 and 6, the excess/deficiency scale 10 and the height pointer 16 are removed, the height scale 26 is drawn directly on the transparent plate 5, and the health rank display line is drawn at 42, 42, The structure is the same as the first embodiment except that four lines 43, 44, and 45 are drawn. Equivalent parts are denoted by the same reference numerals and their description will be omitted. The height scale 24 is provided from 140 cm to 180 cm, and is provided so that exactly 160 cm is located on the extension line of the fixed pointer 4. Health rank display line 4
2, 43, 44, and 45 are drawn in the same way as the display lines 26 and 28 of the first embodiment, except that the standard weight corresponding to each height scale 24 is multiplied by 0.8, 0.9, 1.1, and 1.2. , these display lines 42, 43, 44, 45
Five areas 46, 47, 48, 4 divided by
Numbers 9 and 50 are appropriately colored to represent underweight, underweight, normal, overweight, and overweight. This weight scale is also used in the same way as the first embodiment.

Therefore, according to these scales, the height scale is 24
It can be determined from the display lines 26, 28, 42, 43, 44, and 45 which health rank the person to be weighed belongs to in relation to his or her height. Moreover, since each height scale 24 is provided along a line drawn by being displaced toward the center of the rotary scale board 6 in accordance with the rotating direction of the rotary scale board 6, the intervals between the height scales are wide. Furthermore, each display line represents the height and the value obtained by multiplying the standard weight corresponding to the height by a predetermined ratio in polar coordinate format, and the angle between the height scale and the height scale on the extension line of the fixed pointer. They are connected by staggered by the same amount.
Therefore, unlike the conventional display line, the display line does not have a spiral shape. Since height scales and display lines are provided in this way, even people whose height is between the height scales can clearly check whether their weight is normal or not.
You can know whether you are overweight or underweight.

In the above embodiments, a scale for managing the health of obese children and a scale for managing the health of obese and slim people has been described, but the scale can also be used for managing the health of only slim people. Furthermore, although the height scale 24 is provided along the spiral edge 22, it is a line that gradually moves toward the center along the direction of rotation of the rotary scale 6, for example, a circular arc eccentric from the center of the rotary scale 6, or It may be provided along a straight line parallel to a suitable tangent to a circular arc concentric with the dial 6.

As described above, according to this invention, the height scale is provided along a line that gradually moves toward the center while following the rotation direction of the rotary scale, so the scale interval of the height scale becomes larger than before. , it is easy to recognize a specific height on the height scale, and the intervals between the rank display lines drawn based on the height scale with large scale intervals are also wide, making the scale easy to read the rank, and therefore A scale that is easy to use can be obtained to know the rank of overweight, overweight, etc.
