Examples of the strength measuring device for portable strength training equipment 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 perspective view showing an embodiment of a muscle strength measuring device for portable strength training equipment according to the present invention.

Referring to Figure 1, the muscle strength measurement device (A) includes a coupling module 100 and a load cell (200).

The coupling module 100 is detachably coupled to a wire configured to pull a weight of a strength training device, and may be configured on one side (upper surface in FIG. 1) of the load cell 200.

At this time, the coupling module 100 is the force generated by the change in tension of the wire as shown in FIG. 4 (Fig. It is preferable that the boxed arrow in ) is applied in the vertical direction to the load cell 200.

In this way, when the force due to the change in tension of the wire is transmitted to the load cell 200 in the vertical direction, more detailed and precise measurement can be performed compared to the method of transmitting the force in the longitudinal direction.

To this end, the coupling module 100 is not coupled so that the wire is disposed parallel to the load cell 200, but is coupled so that the wire is bent at least once in the middle of the load cell 200 as shown in FIG. Force may be applied in the vertical direction in the bent portion.

The load cell 200 is configured on one side (upper surface in FIG. 1) of the coupling module 100 and measures the tension applied to the wire coupled to the coupling module 100, as described above with reference to FIG. 4 Similarly, in a state in which the wire is coupled to the coupling module 100 so as to be bent at least once, the force applied by the bent portion of the wire may be measured.

FIG. 2 is an exploded perspective view illustrating the coupling module shown in FIG. 1 in more detail, and FIG. 3 is a view illustrating the installation method of FIG. 1 .

First, the coupling module 100 may include a fixed coupling portion 110, a loading portion 120, and a guide coupling portion 130, as shown in FIGS. 1 and 2.

The fixed coupling part 110 is fixedly coupled to a certain point of the wire, and can be firmly coupled so that the coupled point remains constant without changing even when the wire moves and tension changes.

Looking at this in more detail, the fixed coupling part 110 is detachably coupled to the fixed base 111 coupled to one side of the load cell 200 (the surface facing the lower right direction in FIG. 2) and to the fixed base 111. It may include a fixed cap 112 to be.

And, at least some of the fixing base 111 and the fixing cap 112, as shown in FIG. 3, a wire fixing groove 113 to which the wire W is coupled may be formed.

On the other hand, as described above, the fixed coupling part 110 should be firmly coupled to a certain point of the wire (W). For this purpose, in the present invention, the cross section of the wire fixing groove 113 is smaller than the cross section of the wire (W). It can be formed as a cross section.

Accordingly, when the fixing cap 112 is coupled to the fixing base 111 in a state where the wire W is disposed in the wire fixing groove 113, the fixing cap 112 presses the wire W, thereby fixing the coupling Part 110 may be firmly coupled to the wire (W).

On the other hand, the guide coupling portion 130 is coupled so that the coupling position with the wire (W) can be changed according to the movement and tension change of the wire, and is disposed at a predetermined distance from the fixed coupling portion 110, and the wire ( W) can be coupled to guide the movement.

Looking at this in more detail, the guide coupling part 130 is detachably coupled to the guide base 131 coupled to one side of the load cell 200 (the surface facing the lower right direction in FIG. 2) and the guide base 131. It may include a guide cap 132 to be.

In addition, at least some of the guide base 131 and the guide cap 132, as shown in FIG. 3, a wire guide groove 133 to which the wire W is coupled may be formed.

At this time, as described above, since the guide coupling part 130 should be able to change the coupling position with the wire (W) according to the movement and tension change of the wire, the wire guide groove 133 is more than the cross section of the wire (W) It is preferable to form a large cross section.

The loading unit 120 is disposed between the fixed coupling unit 110 and the guide coupling unit 1200, and as shown in FIG. 4, the wire W may be coupled to be bent.

Looking at this in more detail, the loading part 120 is coupled to the load cell 200, more precisely, the fixed coupling part 110 and the guide based on the coupling surface of the load cell 200 (the surface facing the lower right direction in FIG. 2). It may be formed to protrude from the portion 120 .

At this time, a pressure guide groove 123 for guiding the movement of the wire W is formed in at least a part of the loading part 120, and as shown in FIG. 3, the wire W is disposed in the pressure guide groove 123. By doing so, when the motion or tension of the wire (W) changes, it can be moved at a constant position.

Through this, even if movement or tension change occurs in the wire (W), it is possible to prevent the wire (W) from being separated from the loading unit 120 and to maintain a stable coupling state.

FIG. 4 is a diagram explaining the method of use of FIG. 1 .

Referring to FIG. 4 , the wire (W) may be coupled to the fixed coupling portion 110 so that the coupling position is fixed, and the coupling location may be changed to the guide coupling portion 130 .

In this way, in the state in which the strength measuring device (A) is coupled to the wire (W), when the measurement subject uses the corresponding strength exercise device, the wire (W) connected to the weight is pulled (solid arrow in FIG. 4) and the wire A change in tension occurs in (W), and as a result, a force (boxed arrow in FIG. 4) is applied in a direction perpendicular to the longitudinal direction of the load cell 200.

The load cell 200 may calculate the change in tension of the wire (W) by measuring such a change in force, and it is possible to measure the muscle strength of the subject to be measured using this.

On the other hand, it has been described above that the present invention enables more accurate measurement compared to the case where the force is applied in the longitudinal direction by allowing the force due to the change in tension of the wire (W) to be applied in the vertical direction of the load cell 200.

In order to make these measurement values more accurate and precise, the load cell 200 of the present invention, as shown in FIG. Two strain gauges (strain gauges, 210) may be configured on each of the rear surfaces).

In addition, the two strain gauges 210 configured on each side may be spaced apart from each other in both directions with respect to the loading part 120 .

In other words, the two stereo gauges 210 configured on at least one side of the load cell 200 may be disposed on both sides of the coupled portion so that the wire W is bent at least once.

The four strain gauges 210 arranged in this way can sense and output a change in tension of the wire W according to the circuit diagram shown in FIG. 7 .

In addition, in order to make these measurement values even more accurate and precise, the load cell 200 of the present invention forms an insertion surface 201 corresponding to the portion to which the loading part 120 is coupled, as shown in FIG. can do.

The insertion surface 201 is formed in a state inserted by a certain depth D1 from the corresponding surface (the lower surface in FIG. 4) of the load cell 200, and the cross section of the load cell 200 at the portion where the insertion surface 201 is formed is Since it is formed with a smaller area than other parts, the amount of change due to the force applied by the wire W may increase.

As a result, since a relatively large deformation occurs in the portion where the insertion surface 201 is formed even with a relatively small amount of change in force, more precise measurement may be possible, and through this, the muscle strength of the subject to be measured in a more subdivided size (unit) can be measured more precisely.

5 is a view showing other embodiments of the coupling module of FIG. 1;

Referring to (a) of FIG. 5 , the fixed coupling part 110 may further include a wire fixing pad 114 on at least a portion of the inner surface of the wire fixing groove 113 .

The wire fixing pad 114 may be made of a material having a certain elastic force, and as shown in FIG. 3, the wire fixing pad 114 is partially deformed in the process of being coupled with the wire W, and various types of wires (W ) Since it is pressed while sufficiently closely adhering to the outer surface, the fixed coupling part 110 can be more firmly coupled to the wire (W).

On the other hand, as described above, the pressing guide groove 123 of the loading part 120 should prevent the wire (W) from being separated in the process of changing the movement or tension of the wire (W).

To this end, as shown in (b) of FIG. 5, the pressing guide groove 123 has a center point of the wire W to be coupled (the center point of the dashed-dot line in FIG. 5) at a certain depth than the outer surface of the loading part 120. By forming it to be located on the inside of (D2), more than 50% of the cross section of the wire (W) can be located inside than the outer surface of the loading part 120, and through this, the wire (W) is effectively prevented from being separated. It can be prevented.

6 is a perspective view illustrating another embodiment of FIG. 1 .

Referring to FIG. 6 , an additional function module 300 may be further configured on one side of the coupling module 100, more specifically, on one side of the coupling module 100 in the longitudinal direction.

In the process of describing FIG. 4 above, the four strain gauges 210, two of which are spaced apart from each other on the front and rear surfaces of the load cell 200, sense the change in tension of the wire W through the circuit diagram shown in FIG. 7. It was explained that it can be output by doing.

Such an output signal is an analog signal, and it may cause difficulties for a user or manager to intuitively determine the measurement result for the subject to be measured.

Therefore, in the present invention, by configuring an indicator for calculating a measured value by analyzing the detection signal measured by the strain gauge 210 of the load cell 200 in the additional function module 300, the user or manager can Information can be intuitively and easily identified. Here, the output method of the indicator is not limited to an analog gauge, and may include a digital display.

In addition, the additional function module 300 may include a wireless communication unit for performing wireless communication with the user terminal, through which the muscle strength measuring device (A) is converted by a signal or indicator measured on the user's (manager's) smartphone. data can be transmitted.

Accordingly, the user (manager) checks the information received with his/her smartphone, and based on this, not only enables the establishment of an appropriate exercise plan for the subject to be measured and efficient operation and management, but also improves the subject's physical strength and can improve your health.

In the above, the portable muscle strength exercise 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.
