Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height and weight scale normally used in medical and health care, and more particularly to a height and weight scale capable of accurately measuring weight.

[0002]

2. Description of the Related Art Conventionally, when measuring height and weight, a height scale having a height measuring mechanism combined with a weight measuring mechanism is used. That is, when measuring the height, the person to be measured makes the person's back tightly contact with the columnar scale which is vertically installed and installed so that the cursor can be slid vertically.
The person himself / herself also measures the scale with the back vertical. In addition, the body weight is measured by a weight scale installed inside the pedestal on which the person to be measured is placed while measuring the height. In recent years, it has become possible to automatically measure the height and weight of a person who sits on a pedestal when measuring the height.

[0003]

As described above, in the conventional height scale, the person who is trying to measure is measured by placing his back on the pillar of the height scale and making himself vertical as seen in the conventional height scale. There is a tendency to try to get it. That is, although the automatic height scale also measures the weight at the same time, when the back is brought into contact with the pillar, a part of the weight is applied to the pillar itself, which has nothing to do with the weight measuring unit, and therefore the weight is accurate. There is a fear that there will be no, and the numbers tended to be unstable. If the weight is not stable as described above, it may not be possible to efficiently measure the height and weight of a large number of people such as a school in a short time.

The present invention has been made by paying attention to the above-mentioned problems, and it is possible to accurately measure the weight and height even when the person to be measured contacts his / her back with the back pillar, and a weight scale is provided. It is an object of the present invention to provide a height and weight scale that can promptly stabilize the numerical values displayed and displayed and can measure them efficiently and accurately in a short time.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a height scale with a column on which the cursor is attached so as to be vertically movable at the upper end of the pedestal. A weight measuring device for sensing the weight of the person to be measured and a weight sensing unit are placed on the pedestal, and a columnar guard is set up in front of the column integrally with the weight sensing unit. It is characterized by being installed and placed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 (B) is a diagram showing the configuration of the height and weight scale of the present invention, and FIG. 1 (A) is a sectional view (plan view) taken along line XX of FIG. 1 (B). At the upper end of the pedestal 2, a column 1 for height measurement is erected. A cursor 4 is attached to the pillar 1 so as to be vertically movable. The pillar 1 has a hollow inside, and a pole 3 is erected in the hollow inside so that the cursor 4 is provided.
Is attached to the pole 3 by a fixture 5 so as to be vertically movable. As the vertical movement mechanism of the cursor 4, various types such as a screw type, a mechanism using a pulley and a wire, and the like can be considered.

Next, a weight measuring device 6 for sensing the weight of the person to be measured is placed on the pedestal 2, and a weight sensing portion 8 having a flat top surface is placed on the weight measuring device 6. Is placed. At the front part of the pillar 1, a columnar guard 7 formed integrally with the weight sensing portion 8 is arranged upright. The upper end of the columnar guard 7 is connected to the swinging link 9 at the upper end of the column 1 so that it can be swung. This is because the columnar guard 7 is laterally moved at some time. This is to prevent the weight sensing unit 8 from being adversely affected when it is strongly pressed.
The swing link 9 may be supported at an intermediate portion instead of being provided at the upper end, but the columnar guard 7 is solid, the weight sensing portion 8 is strong against moment load, and there are few errors. If so, it may be omitted. Due to the above, no matter how much the person to be measured comes into contact with the columnar guard 7, the weights and weights of the person to be measured and the columnar guard 7 are on the weight-sensing portion 8 and thus affect the measured values. There is no such thing.

The operation when the height scale is configured as described above will be described. When the person to be measured gets on the weight sensing unit 8 and pushes the measurement start switch with the pillar-shaped guard 7 as a back and becomes vertical, or when the weight sensing unit 8 senses the weight and judges that a person has stepped on, the start is started. Takes. After a certain period of time after the start, or after the weight data is stabilized, the weight is measured, and then the cursor 4 descends to measure the height. At this time, the columnar
Without Do 7, the subject often leans against the pillar on the back side, and if the weight is not stable, the measurement takes time and the purpose of efficiently and efficiently measuring a large number of people cannot be achieved. It was However, according to the automatic height scale of the present invention, the user can lean on the pillar-shaped guard 7 so that the weight measurement is not affected and the weight value can be stabilized in a short time.

FIG. 2 shows another embodiment of this automatic height scale as viewed from the same direction as the sectional view taken along the line XX in FIG. 1 (B). That is, the columnar guard 7 on which the person to be measured leans is installed in front of the column 1 as two pipe-shaped guards, and the columnar guard 7 is installed.
The cursor 4 may be configured to move up and down between the pipes of the door 7.

FIG. 3 is an example view showing the cross-sectional shape of the columnar guard 7. That is, the columnar guard 7 is shown in FIG.
It may have a U-shaped cross section as shown in FIG.
Two pipes may be used as shown in (B), or one having an elliptical cross-sectional shape as shown in FIG. 3 (C). As described above, the columnar guard 7 may have various shapes.

As described above, the main point of the height and weight scale of the present invention is that, when the person to be measured conventionally measures the height, it causes the back pillar 1 to contact the back to give an error to the weight measurement value. A columnar guard 7 is installed in front of the column 1 integrally with the weight sensing unit 8 to prevent this. Therefore, even if the person to be measured leans against the columnar guard 7, this force is a part of the internal force, that is, a part of the weight measurement value and does not cause an error in weight measurement.

[0012]

As described above in detail, according to the height scale of the present invention, when measuring the height and weight, it is possible to accurately measure the weight in a short time even if the person to be measured leans against the back girder. You can Further, by providing the columnar guard with the swinging link, the weight sensing unit can be protected when an unexpected force is applied in the lateral direction. Further, according to the height scale of the present invention, since the numerical value at the time of measuring the weight is quickly stabilized, the height and weight of a large number of people can be quickly measured.
