This strain gauge 130 is a sensor that detects a minute change (strain) in mechanical dimensions as an electrical signal, and the degree of strain of the elastic body 121 that occurs when the measurement subject grips the grip 110 changes the resistance value. It is something that changes.
In this and the following description, “inner surface” refers to the side close to the opening in the curved portion of the U-shaped elastic body 121, and “outer surface” refers to the curve of the U-shaped elastic body 121. In the portion, the side far from the opening is shown.

The elastic body 121 is preferably made of stainless steel, has a thickness of about 0.5 mm to 2 mm, a radius of the curved portion of about 5 mm to 10 mm, and generates distortion with a gripping force of 0 kgf to 50 kgf.

As the elastic body 121, a material having excellent spring elasticity such as beryllium copper can be used in addition to stainless steel.

  By setting it as such a structure, it can be set as the grip strength measuring apparatus 1 which can measure the grip strength of a weak grip strength person, such as a child and an elderly person, accurately, and can evaluate a therapeutic effect effectively. In addition, by using stainless steel having excellent workability and corrosion resistance, the elastic body 121 can be easily manufactured and has durability. Furthermore, the elastic body 121 having a high strain sensitivity can be obtained by forming the elastic body 121 with a U-shape made of stainless steel that is elastically deformable and has a spring effect. Therefore, the grip strength meter 100 with high measurement accuracy can be obtained.

The length of the strain gauge 130 in the longitudinal direction is preferably about 0.5 mm to 2 mm, more preferably about 1 mm.

The connecting tool 122 is for connecting the grip part 110 and the elastic body 121, and includes a screw 122a and a fastener 122b, as shown in FIGS.
The fastener 122b is a female screw corresponding to the male screw 122a, and has a rectangular parallelepiped shape as shown in FIGS.
The screws 122a and the fasteners 122b are preferably formed of stainless steel. By using stainless steel excellent in workability and corrosion resistance, the screw 122a and the fastener 122b that are easy to manufacture and have durability can be obtained.

As shown in FIGS. 2 and 3, the grip strength meter 100 having the above-described configuration has a pair of bar-shaped upper and lower grips 111 and 112 arranged opposite to each other in parallel at a constant interval, and an elastic body 121 is attached and seated. The screw 122a is passed through the through hole 111a and the through hole 121a in a state of being seated on the portion 111b, and is screwed to the stopper fitting 122b.
The grip strength meter 100 thus formed has the following effects.

Further, the mounting seat 111b and the seating surface 121d are both substantially rectangular planes perpendicular to the inner wall 111c, and the fastener 122b has a rectangular parallelepiped shape so that the seating surface 121d is brought into close contact with the seating portion 111b. Can be made. Therefore, the upper grip 111 and the lower grip 112 can be more firmly connected by the connecting portion 120.
When the elastic body 121 is seated on the mounting seat portion 111b, a spacer (not shown) can be screwed in a state where the spacer is detachably interposed between the seat portion 111b and the elastic body 121. . By interposing the spacer, the gap between the upper grip 111 and the lower grip 112 can be adjusted to a size that is easy to grip according to the age of the person to be measured.

  In addition, a pair of elastic bodies 121 formed of stainless steel in a U-shape are arranged opposite to each other in opposite directions, and a strain gauge 130 is provided on the inner surface and outer surface of the curved portion, so that the gripping force of the subject can be accurately measured. It can be measured well. Further, by making the elastic body 121 to be distorted with a grip force of 0 to 10 kgf, the measurement unit can be 10 kgf, and the grip force meter 100 capable of precise measurement can be obtained.

  Further, by providing the wiring storage portion 111d and providing the wiring lead-out groove 111e at the end of the wiring storage portion 111d, the wiring 400 connected to the strain gauge 130 is connected to the inside of the grip portion 110 as shown in FIG. And can be easily pulled out of the grip strength meter 100. Therefore, connection and management of the wiring 400 connected to the strain gauge 130 can be facilitated.

  Further, by providing the grip portion 110 with a pair of convex portions 111a, as shown in FIGS. 1 and 3B, the grip portion 110 is connected to the strain gauge 130, stored in the wiring storage portion 111d, and moved to the outside of the grip meter 100. Most of the drawn wiring 400 and the connecting portion 120 can be arranged inside the grip meter 100. Therefore, it is possible to make the grip strength meter 100 easy to maintain because dust or the like hardly accumulates in each part during use and storage.

  Further, by providing the recess 111h, the head of the screw 122a does not protrude from the surface of the grip portion 110. Therefore, when carrying the grip strength meter 100, it is possible to reliably prevent the finger of a child or an elderly person from being damaged. Therefore, the grip strength meter 100 in consideration of safety can be obtained.

The calculation control means 200 is for calculating and controlling the grip strength value detected by the grip strength meter 100. Specifically, the calculation control means 200 is mainly a change in resistance value detected by the strain gauge 130 provided in the grip strength meter 100. This is a so-called strain gauge display for converting into digital values.
As shown in FIGS. 1 and 6, the arithmetic control means 200 includes a bridge circuit 210 having a strain gauge 130 as a circuit element, an amplifier 220, an A / D converter 230, a central processing unit 240, a setting device. 250, a display panel 260, and a memory 270, and is connected to a power source 500.

  The bridge circuit 210 constitutes a basic circuit for strain measurement, and is electrically connected to four strain gauges 130 as shown in a simplified manner in FIG. More specifically, as shown in FIG. 7, the bridge circuit 210 is formed by a so-called 4-gauge method in which all four sides of the bridge are configured by strain gauges. That is, the left inner strain gauge 130a and the right inner strain gauge 130c are connected to each other, and the left outer strain gauge 130b and the right outer strain gauge 130d are connected to each other, and the change in resistance value of the four strain gauges 130 is expressed as a voltage. The distortion of the elastic body 121 is detected by converting it into a value.

By forming the bridge circuit 210 by the so-called 4-gauge method in this manner, the strain to be measured can be efficiently converted into an electric signal, and the bridge can be completed with only the strain gauge 130 portion.
In FIG. 7, in order to show the configuration of the bridge circuit 210 in an easy-to-understand manner, the configuration in which the wiring 400 is drawn out from the wiring drawing groove 111e is not used.

  The amplifier 220 is for amplifying voltage values detected by the four strain gauges 130.

  The A / D converter 230 is for converting the voltage value detected by the four strain gauges 130 into a digital value.

  The central processing unit 240 is a unit that supervises the arithmetic control unit 200, and converts the digital value converted by the A / D converter 230 into a grip strength value together with the setting unit 250.

  The display panel 260 is a panel for displaying the grip strength values converted by the central processing unit 240 and the setting device 250.

  The memory 270 is for storing the grip strength values converted by the central processing unit 240 and the setting device 250 in the calculation control means 200.

The display means 300 is for displaying the grip strength value calculated and controlled by the arithmetic control means 200. Specifically, as shown in FIG. 1, the display means 300 is connected to a power source 500 and is calculated via a cable 600. This is a so-called general computer for performing digital communication with the control means 200 and displaying a grip strength value calculated and controlled mainly by the calculation control means 200.
The display means 300 includes a control unit 310 that incorporates a CPU or the like and controls and controls the display unit 300, a display unit 320 including a liquid crystal display that displays a grip strength value calculated and controlled by the calculation control unit 200, and various types. The control unit 310 includes software (not shown) (such as Visual Basic) that can display and manage grip strength values. In addition, the software includes a program for outputting a specific recognition display to the display unit 320 when the grip strength value calculated and controlled by the calculation control means 200 is equal to or greater than a preset grip strength value. Yes.

  As the cable 600, for example, an RC232C cable can be used. By using the RC232C cable, medium / low speed serial communication can be performed between the arithmetic control unit 200 and the display unit 300. Of course, the cable 600 is not limited to the RC232C cable, and any other cable may be used as long as digital communication can be performed between the arithmetic control unit 200 and the display unit 300. A configuration may be used in which wireless communication is performed without using.

  Next, with reference to FIGS. 8-12, the flow of operation | movement of the grip strength measuring apparatus 1 which concerns on this invention, and the display state of a grip strength value are demonstrated.

  First, referring to FIG. 8, the strain gauge 130 is distorted when the measurement subject grips the grip 110, and the resistance value of the strain gauge 130 changes (steps S <b> 700 to S <b> 720).

  Next, the changed resistance value is converted into a voltage value by the bridge circuit 210. The voltage value is amplified by the amplifier 220 and then converted into a digital value by the A / D converter 230. Then, the digital value is converted into a grip strength value by the central processing unit 240 and the setting device 250 and displayed on the display panel 260. At the same time, the grip strength value is stored in the memory 270 (steps S730 to S770).

  Next, when the communication start button 321 of the display unit 320 shown in FIG. 10 is pressed, digital communication between the calculation control unit 200 and the display unit 300 is started, and the grip strength value detected by the calculation control unit 200 is transmitted via the cable 600. To the control unit 310 of the display means 300. The transmitted grip strength value is displayed on the display unit 320 as a normal display by software built in the control unit 310 (steps S780 to S790).

More specifically, as shown in FIG. 10, when the communication start button 321 on the display unit 320 is clicked, the reception count unit 322 starts counting, and the grip strength value is displayed on the grip strength value display unit 323 as a real time value, a peak value, or the like. As a numerical value and a bar graph, and as a relationship graph between time and grip strength value. Of course, the display form of the grip strength value is not limited to these configurations, and can be changed as appropriate.
The measured grip strength value is stored and managed in a storage unit of the display unit 300 (not shown).

Then, it is determined whether or not the transmitted grip strength value is equal to or greater than a preset grip strength value (step S800).
When the transmitted grip strength value is less than the preset grip strength value, normal display is performed on the display unit 320, and the measurement is terminated when the measurer performs a measurement end process on the control unit 310 ( Step S810).
When the transmitted grip strength value is equal to or greater than the preset grip strength value, a specific recognition display is further output to the display unit 320 in accordance with the grip strength value, and the measurer sends the control unit 310 to the control unit 310. The measurement is completed by performing the measurement end process (steps S820 to S860).
Here, the “specific recognition display” indicates that the measurement subject can recognize with any of the five senses.

More specifically, as shown in FIGS. 10 and 11, the bar graph displayed on the bar graph portion 323 a indicating how much the measured grip strength value is the degree of achievement with respect to the set value is 20 degrees of achievement. If it is%, a “telephone bell” sound is heard and “telephone mark” is displayed on the specific display unit 324 (step S820). On the other hand, if it is 40%, the sound of “bird cry” sounds and “bird character” is displayed on the specific display unit 324 (step S830). If the degree of achievement is 60%, a “horse cry” sounds and “horse character” is displayed on the specific display unit 324 (step S840). If the degree of achievement is 80%, the sound of “elephant cry” sounds and “elephant character” is displayed on the specific display unit 324 (step S850).
FIG. 11 shows a case where the degree of achievement is 80%, the sound of “elephant cry” is sounded, and “elephant character” is displayed on the specific display unit 324.
