Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a forward bend meter used for measuring body flexibility.

<Prior Art> In order to measure the flexibility of the body, conventionally, the distance between the top surface of a measurement table and the hand of the subject bent forward on the measurement table was measured using an appropriate tape measure.

However, when measuring the degree of anteversion using a tape measure, a measurer is always required in addition to the person being measured, and there are problems in that the measured value may vary depending on the proficiency level of the measurer. It was hot. In addition, when a person to be measured stands on a measurement table and bends forward as in the past, there is a possibility that the person to be measured loses balance and falls from the measurement table. There was the inconvenience that in some cases, an attendant would be required.

<Purpose of the invention> The purpose of the invention is to be able to take any measurement form that suits the characteristics of the person to be measured, and to be able to measure the body without requiring a special measurer or attendant. To provide a forward flexion meter capable of accurately measuring the degree of forward bending.

<Structure of the device> The present device has a box-shaped main body with an open rear surface, and a box-shaped main body with an open rear surface having approximately the same depth and height as the main body and approximately 1/2 the width of the main body on both sides. A pair of left and right auxiliary boxes forming the main body are hinged so as to be horizontally rotatable to form a shape-changeable box, and an inner rail is attached to an outer rail along the vertical direction that is attached to the front center of the main body so that it can be moved back and forth and can be attached and removed. and a slider mounted so as to be able to rise and fall and lock freely through a guide, and to display the height difference between the top surface of the measurement plate fixed to the top surface of the slider and the top surface of the main body in a viewing window provided on the slider. By providing a tape measure wound and biased and housed inside the slider, the distance between the measurement reference plane formed by the top surface of the main body and the top surface of the measurement plate is displayed on a viewing window provided in the slider. That's what I do.

<Embodiment> Auxiliary boxes 2, 2 are provided on the left and right sides of the main body 1, which is box-shaped with an open rear surface, and the main body 1 has an open rear surface.
It is formed into a box shape with an open rear surface and approximately the same depth and height as , and approximately 1/2 the width of the main body 1 . The rear edges of the inner walls of these auxiliary boxes 2, 2 are horizontally rotatably hinged to the rear edges of the side walls of the main body 1 by means of hinges 3, 3. As shown in the figure, the main body 1 is rotated to the rear side to cover the opening, and the main body 1 and the auxiliary boxes 2, 2 are
They form one storage space, or the auxiliary boxes 2, 2 can be rotated to both sides of the main body as shown in FIG. 5 or 6.

A measuring unit 5 is mounted near the front center of the main body 1 via a stay 4 so as to be detachable and movable back and forth.

The stay 4 is formed with an inverted L-shape on its side, and has a long hole 7 extending in the front-rear direction in the horizontal portion 6 that contacts the top surface of the main body 1. is tightened and fixed to the main body 1. The outer rail 10 of the measuring unit 5 is fastened to the vertical portion 9 of the stay 4 along the front surface of the main body 1 using bolts or rivets (not shown).

The outer rail 10 is made of a channel material extending in the vertical direction with an opening on the front surface, and an inner rail 11 made of the same channel material as the outer rail 10 is mounted inside thereof so as to be able to rise and fall freely. are doing. In addition, the outer rail 1 is attached to the vertical part of the stay 4.
By installing ball springs 12, 12 which pass through the inner rail 11 and contact the rear wall of the inner rail 11, the inner rail 1
1 can be locked in any vertical position.

A guide 13 is mounted inside the inner rail 11 so as to be able to rise and fall freely, and ball springs 14, 14 protruding from the rear surface of the guide 13 are brought into rolling contact with the inner surface of the rear wall of the inner rail 11. The guide 13 can be locked at any vertical position relative to the rail 11. A stopper 15 is fixed to the upper end of the inner rail 10 for regulating the rising end of the guide 13 and for regulating the descending end of the inner rail 11.

On the other hand, a slider 16 is fixed to the front end of the guide 13 that projects forward from the inner rail 11,
Tape measure 18 wound and biased by coil spring 17
is mounted inside the slider 16. 19
20 is a bracket that holds the tape measure 18; 20 and 20 are screws that tighten and fix the bracket 19 to the guide 13; 21 is an outer case of the slider 16; 22 is a viewing window provided in the outer case 21; and 23 is the viewing window. A reference line 22 is provided, and 24 is a measurement plate fixed to the top surface of the slider 16.

Then, the tape measure 18 is extended through the inside of the inner rail 11 to the vicinity of the lower end of the outer rail 10 via a roller 25 that is pivotally supported by the guide 13, and the tip thereof is fixed to the lower end of the outer rail 10. 1
The measurement reference plane formed by the upper surface of the slider 16
The distance between the measuring plate 24 and the upper surface of the measuring plate 24 fixed to the measuring plate 24 can be read from the tape measure 18 through the viewing window 22. Reference numeral 26 denotes a guide for holding the tape measure 18 close to the viewing window 22, and holders 27, 27 are installed inside the main body 1 to store and hold the outer rail etc. that have been removed from the front surface of the main body 1. . 28, 28 are the main body 1 and the auxiliary box 2,
This is a reinforcing plate that reinforces 2.

When measuring the flexibility of the body using the forward bending meter configured as described above, generally, as shown in Fig. 1, the measuring unit 5 is attached to the front of the main body 1 via the stay 4, and the left and right The auxiliary boxes 2, 2 are each rotated and held on the rear side of the main body to form a substantially square measuring stand when viewed from above. And slider 16
as shown in FIG. Measurement plate 24 with your fingertips while bending
Push down to the limit position.

Then, as the slider 16 is pressed down,
is lowered, and the distance between the upper surface of the measurement plate 24 and the measurement reference plane is displayed on the viewing window 22. In addition, if the numerical value (scale) when the measuring plate 24 is located above the measurement reference plane is +, the measuring plate 24
The numerical value (scale) when is located below the measurement reference plane may be -, and the numerical value (scale) when the top surface of the measuring plate 24 and the measurement reference plane are located on the same plane. ) is set to zero need not be explained in detail. Furthermore, by making the sliding resistance of the inner rail 11 smaller than the sliding resistance of the guide 13, the inner rail 1 is lowered as the measuring plate 24 is pushed down.
Of course, the inner rail 11 and the guide 1 can be lowered preferentially, and the inner rail 11 and the guide 1 can be lowered as necessary.
Three fixing means may be provided.

In addition, when used by a subject who is anxious about bending forward while standing upright, such as an elderly person, the auxiliary boxes 2, 2 can be rotated to both sides of the main body 1 as shown in Fig. 4, for example. Lay down the main body 1 and auxiliary boxes 2, 2 on the floor so that the unit 5 is on top, touch the measuring reference surface with the foot thrown forward, bend forward, and touch the measuring plate 24 with your fingertips in the same way as in the previous case. Push forward. Then, in this case as well, the distance from the measurement reference plane to the upper surface (pressing surface) of the measurement plate 24 is displayed on the viewing window.

Therefore, the direction in which the forward bending meter is used (the direction in which it is pressed down) can be changed in accordance with the physical characteristics of the person being measured, thereby making it possible to avoid a situation where the person loses his/her balance due to forward bending and falls from the measuring table.

When the forward bending meter is not used, remove the setscrew 8 and attach the measuring unit 5 to the main body 1 as shown in Fig. 5.
After that, the left and right auxiliary boxes 2, 2 may be rotated to the rear of the main body and fixed with clasps (not shown).

In the embodiment, the stopper 15 at the upper end of the inner rail 11 can be used as an auxiliary measuring plate, but this is not limited to the embodiment, and
The locking mechanism for the inner rail 11 and guide 13 is not limited to the embodiment.

<Effects of the invention> In this invention, auxiliary boxes are hinged to both sides of the main body that form the measurement reference surface, and by changing the position of the auxiliary boxes, the shape of the measurement reference surface can be changed, and the sliding direction of the slider can be changed. This makes it possible to accurately measure not only forward bending from an upright position, but also the degree of forward bending from a seated position with legs thrown forward, without the need for special assistance. .
