Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a health care scale. Conventionally, various types of scales have been devised to measure the total weight of the human body, but no consideration has been given to measuring the left and right weight balance of the human body when standing.

If you actually observe a person standing on a scale, you will notice that one of their shoulders is slumped, or that sickly people sway when standing.

The present invention can obtain data that can be used as guidelines for optimizing and correcting the center of gravity by appropriately detecting the left and right weight balance and the degree of rocking when measuring weight while standing. This is a weight scale that is used to measure (1) left and right weight balance when the human body is standing, (2) detect the degree of rocking, and (3) confirm the consistency of height and weight. It is a total.

Accordingly, the present invention is a weight scale that is basically equipped with a measurement and display mechanism for measuring and displaying the weights of the left and right sides of a human body.

It is also proposed to add one or all of the following to this scale: a total weight display mechanism, a left and right weight difference display mechanism using point O as a fulcrum, a posture swing detection mechanism when standing, and a height gauge. ing.

Next, an embodiment of the weight scale according to the present invention will be described based on the drawings.

FIG. 1 is a perspective view of one embodiment, showing a weight scale prototyped for medical use.

The scale includes a base plate 2 having a bullet material 1, a top plate 3, left and right independent footboards 4, 5 to which artificial grass or convex bullets are attached, and weight scales on the left and right that are linked to an O-point adjustment knob 6. A display case 11 having an inclined transparent window 10 for storing the plates 7, 8, a total weight scale plate 9, and the scale plates 7, 8, 9, and embedded between the step plates 4, 5 for detecting postural fluctuation when standing. a vibration meter 13, a display scale 14 extending around it, and an outward knob 1 at the top end.
5, and a bent part 17 that is bent at a right angle and has a length that reaches overhead.
It has a built-in tape measure type height meter 18 formed with.

The left and right weight display mechanisms of the human body are provided with respective display mechanisms that operate depending on the load on the footboards 4 and 5.

As a method for measuring and displaying the load, any known technique may be used, regardless of whether it is mechanical or electrical, and for example, a digital display may be used.

Further, a total weight display mechanism that totals the left and right loads, a mechanism that displays the difference in left and right loads, etc. can be provided.

In particular, if it is an electrical measurement, various displays and miniaturization are easy.

Figure 2 shows an example of a weight display mechanism.
A lever 20 is provided, the outer end of which is supported by footboards 4 and 5 on which the weight of the person to be measured is placed separately on the left and right sides, and whose one end is held by a well-known suspension support mechanism 19, and the lever 20 is lowered. This moves the rack 21, rotates the pinion 22 that supports the left and right weight scale plates 7 and 8, respectively, and displays the load on each footboard 4 and 5.

A spring 23 maintains the meshing of the rack 21 and pinion 22.

The ends of the left and right racks 21 are connected to the shaft of a piston 24 of a transmission mechanism using a liquid-mediated link 29 that transmits the left and right loads in total;
9 is a piston 25 that transmits the movement of the rack 21;
is provided.

A rack 26 is provided on the shaft of the piston 25 and meshes with a pinion 27 that supports the total weight scale plate 9. When the piston 25 operates, the pinion 27
It rotates to display the total weight.

Next, the posture swing detection mechanism during standing is as follows:
A vibration meter 13 is embedded in the vibration meter 13, and a display scale 14 extending around the vibration meter 13 is formed. Vibration meter 1
3 is a bubble level type as shown in the first figure, or one small metal ball 32 is placed in a hollow hemispherical interior 31 whose surface is closed with a glass plate 30 with memory as shown in the fourth figure. Insert 33cm of insulating material on the outside on the back side.
An electromagnet 34 coated with is disposed, and confirmation is made by stopping the small metal ball 32 at a swinging position by magnetic force during vibration due to postural swing.

This type of vibration meter 13 can be constructed by attaching a radial memory to the hemispherical inner surface, providing an elastic material 1 to the base plate 2, and connecting the tread plates 4 and 5 with a shaft 35.
Its operability becomes clear.

In addition, a display scale 14 extending around the vibration meter 13
In addition to being able to measure the length of the legs, as shown in Figure 3, it is also possible to project the body shape and the movement of the body using the vertical beam of light from the ceiling, and the state of the body shape and movement can be detected. With experience and training, it can be used as a standard for visually measuring the degree of shaking.

In addition, FIG. 3 shows a case in which the display case 11 is connected separately from the main body of the scale to facilitate observation.

When weighing the scale of the present invention by placing both feet on the respective treadles 4 and 5, first, the unbalance of the weight being borne by each foot is reflected on the respective display scale plates 7 and 8.
is shown.

Also, the weight display and the left and right weight difference display are shown.

This allows it to be used as material for posture correction, etc.

Also, pull out the tape measure height meter 18, extend it, bend the bent part 17, and measure the height by placing it on the top of the head.
By comparing the height and weight table 16, it is possible to check whether the person is overweight or the like.

Furthermore, sickly people tend to sway during weighing due to their sense of balance, as shown in Figure 3.

In this case, the degree and width of the vibration can be detected more objectively using the vibrometer 13.
You can make an early perception of your physical condition.

As described above, according to the present invention, it is possible to measure the weight balance between the left and right sides of the human body, and in addition, it is possible to objectively detect the proper posture and sense of balance, so it is extremely useful as a health management scale.
