Hereinafter, each configuration is described. The strength training device according to the first embodiment may be a leg press.

The base support 110 may have a structure in which a first support extending in a first direction and a second support extending upwardly from one end of the first support are combined. The second support may be used as a backrest.

The sheet 120 and the external force transmitting structure 130 may be mounted on the first support body to be spaced apart from each other. On the other hand, the actuator 140 and the controller 300 may be disposed inside the first support. According to one embodiment, the external force transmission structure 130 may have a footrest shape that is in contact with the user U's feet and receives an external force through the user's feet.

The sensor unit 200 may include a weight sensor 210, a pressure sensor 220, and a force sensor (not shown). According to one embodiment, the weight sensor 210 may be disposed inside the sheet 120 . Alternatively, the pressure sensor 220 and the force sensor may be disposed inside the external force transmitting structure 130 .

The weight sensor 210 may sense whether or not the user is seated on the seat 120 . Specifically, when the weight change measured by the weight sensor is smaller than the reference change amount, it may be determined that the user is seated on the seat. When it is determined through the weight sensor 210 that the user is seated on the seat 120, it may be determined that the user is exercising. In contrast, when the weight change measured by the weight sensor is greater than the reference change amount, it may be determined that the user is separated from the seat 120 . When it is determined that the user is separated from the seat 120 through the weight sensor 210, it may be determined that the user is not exercising. The weight sensor 210 may sense whether the user is sitting on the seat 210 and then generate exercise information. The generated exercise information may be provided to the control unit 300 to be described later.

The pressure sensor 220 may sense whether or not the user exercises through the strength training apparatus. Specifically, as shown in FIG. 4 , when a change in pressure due to the external force is sensed in the external force transmitting structure 130 , it may be determined that the user is exercising. In contrast, when the pressure change due to the external force is not sensed in the external force transmitting structure 130, it may be determined that the user is not exercising. The pressure sensor 220 may sense whether or not the user has exercised through the strength exercise equipment and then generate whether or not to exercise information. The generated exercise information may be provided to the control unit 300 to be described later.

The force sensor may sense the magnitude of the external force applied to the external force transmitting structure 130 . The force sensor may generate external force information after sensing the magnitude of the external force. The generated external force information may be provided to the controller 300 to be described later.

The control unit 300 may generate actuator driving information based on the exercise information and the external force information provided from the sensor unit 200 . Specifically, when it is determined that the user is exercising by receiving the exercise information from the sensor unit 200, the control unit 300 may drive the actuator 140 to generate a repulsive force. In this case, the control unit 300 may control the magnitude of the repelling force generated by the actuator 140 to be smaller than the magnitude of the external force through the external force information provided from the sensor unit 200 .

In contrast, when it is determined that the user is not exercising after receiving the exercise information from the sensor unit 200, the control unit 300 controls the actuator 140 to stop driving or the actuator 140 The magnitude of the repulsive force generated from may be controlled to be reduced.

It can be.

In contrast, in the case of a mechanism that performs muscle strength exercise through an actuator without the sensor unit 200 and the controller 300, the external force transmission structure is rapidly caused by the repulsive force by the actuator when the user suddenly stands up. Since it can be moved, a safety accident in which the user collides with the external force transmission structure may occur. In addition, in the case of using weights like conventional strength exercise equipment, when the user suddenly gets up, the external force transmission structure is rapidly moved by the weight, so that a safety accident in which the user bumps into the external force transmission structure may occur.

More specifically, as shown in FIGS. 3 to 6, the user U of the strength training apparatus according to the first embodiment of the present invention leans his back against the second support after sitting on the seat 120 and An external force F ₁ may be applied to the external force transmission structure 130 while the foot is placed on the external force transmission structure 130 . In this case, the actuator 140 generates a repulsive force (F 2 ) in the opposite direction to the external force (F ₁ ) applied by the user (U), and the generated repulsive force ( _{F 2} ₎ is applied to the external force transmission structure 130 It can be applied to the user U through. That is, when the user U applies a pushing force F ₁ to the external force transmitting structure 130 through the foot, the actuator 140 pushes in a direction opposite to the direction of the force applied by the user U A force (F ₂ ) may be generated and the generated force may be applied to the user through the external force transmitting structure 130 . Accordingly, the user U may perform strength training by receiving resistance by the external force F ₁ and the repulsive force F ₂ .

In addition, when the user U is separated from the mechanical unit 100, the sensor unit 200 may sense this and provide information on whether or not to exercise to the control unit 300. The controller 300 may control the operation of the actuator 140 to stop when it is determined that the user U is not exercising through the exercise information. Accordingly, even if the user U is rapidly separated from the mechanical unit 100, the movement of the external force transmitting structure 130 can be stopped, thereby preventing a collision between the user U and the external force transmitting structure 130. It can be.

Accordingly, the user U may perform strength training by receiving resistance by the external force F ₁ and the repulsive force F ₂ .

In the above, the strength training apparatus according to the embodiments of the present invention has been described. Hereinafter, a strength training apparatus according to a modified example of the present invention will be described.

변형 예에 따른 근력 운동 기구Strength training apparatus according to the modified example

The strength exercise apparatus according to the first modified example of the present invention may have the same configuration as the strength exercise apparatus according to the first to third embodiments. However, in the strength training device according to the first modified example, a plurality of user recognition sensors may be disposed in the seat 120 . According to one embodiment, all of the plurality of user recognition sensors disposed in the seat 120 may be made of weight sensors. In addition, the strength training apparatus according to the first modified example may further include an alarm unit (not shown).

The sensor unit 200 may sense whether the user is exercising in a correct posture through the weight measured by the plurality of user recognition sensors. Specifically, when the weight measured by each user recognition sensor is constant within an error range, it may be sensed that the user is exercising in a correct posture. In contrast, when the weight measured by one user recognition sensor exceeds the error range than the weight measured by another user recognition sensor, it may be sensed that the user's exercise posture is incorrect.

When the user's exercise posture is detected as being incorrect through the sensor unit 200, the sensor unit 200 may generate alarm information and provide the generated alarm information to the alarm unit. The alarm unit may generate an alarm signal through alarm information provided from the sensor unit 200 . The user can recognize that the exercise posture is wrong through the alarm signal generated by the alarm unit. Accordingly, the user can easily maintain a correct posture while performing strength training through the strength training apparatus.

In addition, when the weight change measured through the user recognition sensor decreases while the user applies a pulling force to the external force transmitting structure 130, the sensor unit 200 indicates that the user's exercise method is incorrect (for example, , exercising using body weight rather than muscle strength). When it is sensed that the user's exercise method is incorrect through the sensor unit 200, the sensor unit 200 may generate alarm information and provide the generated alarm information to the alarm unit. The alarm unit may generate an alarm signal through alarm information provided from the sensor unit 200 . The user can recognize that the exercise method is wrong through the alarm signal generated from the alarm unit. Accordingly, the user can easily maintain the correct exercise method while performing the strength exercise through the strength exercise device.

The alarm unit may generate an alarm signal generated due to an incorrect exercise posture and an alarm signal generated due to an incorrect exercise method to be different from each other. Accordingly, the user can easily distinguish between a case in which the exercise posture is incorrect and a case in which the exercise method is incorrect.

The strength exercise apparatus according to the second modified example of the present invention may have the same configuration as the strength exercise apparatus according to the first to third embodiments. However, the strength training apparatus according to the second modified example may further include an interface capable of selecting an exercise model. A user can select various exercise models through the interface.

Specifically, a first exercise model, a second exercise model, a third exercise model, and a fourth exercise model are displayed on the interface, and the user selects any one of the first to fourth exercise models to strengthen muscle strength. exercise can be performed. Descriptions of the first to fourth motion models, together with the first to fourth motion models, may be displayed on the interface (display device). The first to fourth exercise models may correspond to muscle strength exercise routines of famous celebrities or celebrities, respectively, and the interface displays the names of famous celebrities or celebrities corresponding thereto together with the first fourth exercise model. can do. For example, together with the graph of FIG. 17(a) showing the magnitude of the reaction force of the first exercise model, the word “celebrity Jong-guk Kim's leg press routine” may be displayed on the interface.

For example, as shown in (a) of FIG. 17, the first motion model may be a model operated such that the magnitude of the repulsive force gradually increases and then gradually decreases again as the distance of the external force transmission structure 130 increases. can Unlike this, the second motion model, as shown in (b) of FIG. 17, as the distance of the external force transmitting structure 130 increases, the magnitude of the repulsive force gradually increases and then operates to maintain a constant magnitude at a certain point in time. can be a model In contrast, in the third motion model, as shown in (c) of FIG. 17, the magnitude of the repulsive force gradually decreases as the distance of the external force transmission structure 130 increases, maintains a constant magnitude at a certain point in time, and then resumes again. It may be a model that is operated to gradually increase. Unlike this, the fourth motion model, as shown in (d) of FIG. 17, maintains a first magnitude of repelling force as the distance of the external force transmission structure 130 increases, and then a second magnitude smaller than the first magnitude. It may be a model operated to maintain the repulsive force of Accordingly, since the user can perform strength training through various exercise models, interest in strength training can be aroused.

In addition, various motion models may be further displayed on the interface, and the displayed motion models may change the size of the repulsive force in various ways. According to one embodiment, the exercise models may be composed of muscle strength exercise routines used by celebrities or celebrities. Accordingly, the user can exercise in the same way as a muscle strength exercise routine used by famous entertainers, so that interest in exercise can be further improved.

In addition, the strength training device according to the second modified example may further include an alarm unit. The alarm unit may generate an alarm signal at a point where the magnitude of the repulsive force changes. Accordingly, the user can easily recognize that the magnitude of the repulsive force changes through the alarm signal.

Also, according to an embodiment, the magnitude of the repulsive force transmitted by the actuator may be adjusted according to the user, but the pattern (inclination and change point of the inclination) of the repulsive force according to the motion model may be maintained. In other words, depending on the user, the magnitude of the repelling force may be adjusted X (X is an adjustment constant, a positive number greater than or equal to 0) times, while maintaining the change pattern of the repulsive force of the motion model. For example, the adjustment constant may be arbitrarily set by a user.

Alternatively, for another example, the actuator may apply the same repulsive force as the applied external force from the time the user starts exercising and applies the external force, and the magnitude of the external force applied by the user is selected to determine the initial repulsive force of the motion model. When larger than the size, the external force transmitting structure 130 may move. In this case, an external force greater than the initial repulsive force of the motion model may not be applied from the user to the external force transmission structure 130 for a reference time. In this case, the muscle strength training apparatus sets the adjustment constant so that the size of the initial repulsive force of the exercise model is less than or equal to the size of the external force transmitted from the user, and applies the adjustment constant to the exercise model to apply the repulsive force of the exercise model. can be resized. Accordingly, the user can easily exercise according to the routine of the exercise model and feel interest in exercise. In this case, when the external force transmitting structure 130 is repeated more than a reference number of times from the start position to the end position, the adjustment constant may increase. That is, a first adjustment constant is applied to the motion model from 1 to a first reference number of times (eg, 3 times), and from the first reference number to a second reference number of times (eg, 6 times) to the motion model. A second adjustment constant greater than the first adjustment constant may be applied, and a third adjustment constant smaller than the first adjustment constant may be applied from a second reference number of times or more. Accordingly, the user can exercise according to the routine and pattern of the exercise model based on the same exercise model, but can exercise with different repulsive force according to the number of exercises.

In the above, the present invention has been described in detail using preferred embodiments, but the scope of the present invention is not limited to specific embodiments, and should be interpreted according to the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
