Examples of the physical fitness measurement device according to the present invention can be applied in various ways, and hereinafter, the most preferred embodiment will be described with reference to the accompanying drawings.

1 is a bottom perspective view showing an embodiment of a physical fitness measuring device according to the present invention, and FIG. 2 is a view showing another embodiment of FIG. 2 .

Referring to Figure 1, the physical fitness measurement device includes a weight control pin 100 and a pressure measuring sensor (200).

The weight control pin 100 is inserted to select at least some of the plurality of weights 330 disposed in the strength training device 300 as shown in FIG. 4, and the weights pass through the lifting bar 340 ( 330), and a handle 120 configured to be gripped so that the user can insert or separate the weight control pin 100 from the weight 330.

The pressure measuring sensor 200 is configured on one side of the weight control pin 100 and can measure the force applied by the lifting bar 340 for lifting a plurality of weights. Here, the pressure sensor 200 is a pressure sensor that directly measures the pressure applied to the weight control pin 100, or measures the degree of deformation (bending) of the weight control pin 100 to measure the pressure applied to the corresponding structure It may include a strain gage and the like that measure.

More specifically, as shown in FIG. 6 , the pressure measuring sensor 200 may be configured to correspond to a position where the fitting hole 341 of the lifting bar 340 for lifting the weight 330 is formed.

In other words, the pressure measuring sensor 200 may be configured at a position capable of measuring the force (boxed arrow in FIG. 6) applied to the weight control pin 100 by the lifting bar 340, and the corresponding position is the pressure It may be variously changed according to the type of the measurement sensor 200 and the needs of those skilled in the art.

For example, if the pressure measuring sensor 100 is a pressure sensor that directly detects an applied force as described above, the pressure sensor is a pressure surface among the inner surfaces of the fitting holes 341 of the lifting bar 340 (FIG. 6 It may be configured to correspond to at least a part of the lower surface).

As such, when the pressure measuring sensor 100 is a pressure sensor, the pressure sensor may be installed at a part in close contact with the lifting bar 340 so as to directly measure the force exerted by the lifting bar 340. .

Looking more specifically, the pressure measuring sensor 200 may be configured in the coupling groove 101 formed in the lower part of the body 110 of the weight control pin 100.

For example, as shown in (a) of FIG. 2 , the pressure measuring sensor 200 may be configured in the coupling groove 101 to be exposed.

As another example, as shown in (b) of FIG. 2 , the pressure measuring sensor 200 may be configured to be inserted inside the coupling groove 101, and the outside may be protected by the cover 130.

In this case, when the lift bar 340 presses the cover 130, the cover 130 presses the pressure measuring sensor 200, so the pressure measuring sensor 200 presses the cover 130 to the lift bar ( 340) can be measured.

In addition, when the pressure measurement sensor 200 is a pressure sensor, measurements can be made at multiple points. In this case, the overall average value of the measured values measured at each point may be used, or the average value of the remaining measured values excluding the lowest and highest values of the measured values may be used.

In the case of the strain gauge, the pressure measuring sensor 100 measures the deformation of the weight control pin 100 differently from the pressure sensor, so when deformation or damage occurs due to friction with the lifting bar 340, incorrect data is generated. measurement may occur.

Accordingly, when the pressure measuring sensor 200 is a strain gauge that measures a change in appearance, the corresponding strain gauge is at least a part of the non-pressurized surface (upper surface in FIG. 6) of the inner surface of the fitting hole 341 of the lifting bar 340. It can be configured to correspond to.

In terms of protecting the strain gauge, it may be configured as shown in (b) of FIG. 2, but in this case, the signal measured due to deformation due to the force applied by the cover 130 and the deformation of the weight control pin 100 Since all signals to be measured are generated and interfere with each other, accurate measurement may be difficult.

Therefore, when the pressure measuring sensor 200 is a strain gauge, it is preferable to configure the corresponding strain gauge on the upper surface of the body 110 of the weight control pin 100. Of course, if the interference by the cover 130 can be excluded according to the type or performance of the strain gauge, it is natural that the structure as shown in FIG. 2(b) can be obtained.

FIG. 3 is a block diagram illustrating another embodiment of FIG. 1 .

Referring to FIG. 3 , the physical fitness measurement device may further include a muscle strength measurement module 250 for measuring the subject's maximum muscle strength based on the measurement result of the pressure sensor 200 . At this time, the muscle strength measurement module 250 may include a terminal such as a smartphone or the like configured in the strength exercise device 300 as shown in FIG. 4 or carried by the user.

On the other hand, the subject's maximum muscle strength can be said to be the force applied by the pressure measuring sensor 200 by the lifting bar 340 in a state in which the position of the weight control pin 100 is fixed.

Accordingly, the maximum muscle strength of the subject can be measured in a state in which the weight control pin 100 is inserted into the lowermost weight 330 or inserted into the muscle strength measurement hole 311 formed in the frame 310, as shown in FIG. can At this time, when the weight control pin 100 is inserted into the muscle strength measuring hole 311 formed in the frame 310, it is natural that the lifting bar 340 can also be configured to penetrate the frame 310.

As a result, the muscle strength measurement module 250 has the weight control pin 100 inserted into the lowermost weight 330 of the plurality of weights 300 disposed in the strength exercise machine 300 or the strength exercise machine 300. When inserted into the muscle strength measuring hole 311 formed in the frame 310, the maximum muscle strength of the subject may be measured based on the measured value of the pressure measuring sensor 200.

FIG. 7 is a block diagram illustrating another embodiment of FIG. 1 .

Referring to FIG. 7 , the physical fitness measuring device may further include a pin sensor 260 and a communication module 270 .

The pin detection sensor 260 is configured in at least one of the fitting hole of the lowermost weight 330 and the muscle strength measuring hole 311 of the frame 310 to check whether the weight control pin 100 is fitted, the hall sensor etc. may be included.

For example, when a magnetic material or magnetic tape is formed on the edge of the fitting hole of the lowermost weight 330 and the strength measuring hole 311 of the frame 310, and the hall sensor is configured on the weight control pin 100 In the process of inserting the weight control pin 100, the hall sensor can detect a change in magnetic force, and through this, it is possible to check whether the weight control pin 100 is fitted. At this time, when the hall sensor directly detects the change in magnetic force by the weight 330 according to the material of the weight 330, it is natural that a magnetic material or magnetic tape does not have to be used.

Accordingly, the muscle strength measurement module 250 detects that the weight control pin 100 is inserted into the lowermost weight 330 or the muscle strength measurement hole 311 by the pin detection sensor 260 even if the user does not perform a separate operation. Then, the maximum muscle strength of the subject can be automatically measured.

For example, the muscle strength measurement module 250 may operate in a normal muscle strength measurement mode (when an appropriate weight is selected and the lifting bar reciprocates in the vertical direction), and the weight control pin (by the pin detection sensor 260) 100) is detected, the maximum muscle strength of the subject can be measured by switching from the general muscle strength measurement mode to the maximum muscle strength measurement mode.

Then, when the weight control pin 100 is removed, the muscle strength measurement module 250 can switch from the maximum muscle strength measurement mode to the normal muscle strength measurement mode to measure the subject's normal exercise muscle strength.

The communication module 270 is to transmit the result measured by the pressure measurement sensor 200 to the muscle strength measurement module 250 while interlocking with the pressure measurement sensor 200, the muscle strength measurement module 250 is the strength exercise device 300 When configured in, it may be configured to enable wired communication, and if the muscular strength measurement module 250 is a terminal (eg, a smartphone, etc.) carried by the user, it may be configured to enable wireless communication.

In the above, the physical fitness measuring device according to the present invention has been described. It will be understood that the technical configuration of the present invention can be implemented in other specific forms without changing the technical spirit or essential features of the present invention by those skilled in the art to which the present invention belongs.

Therefore, the embodiments described above are illustrative in all respects and should be understood as non-limiting ones.
