Referring to FIG. 2, the rowing exercise device 200 according to the present embodiment includes a first upper body driver 201a, a second upper body driver 201b, a lower body driver 211, an exercise load control device 230, and a display unit 240. ), A card recognition unit 242, and a support unit 244.

The plurality of upper body driving units 201a and 201b include connecting members 204a and 204b such as a belt or a cable and handles 206a and 206b.

The lower body driver 211 includes a driving footrest 214, a rotating part 215, a saddle 216, a nut 217, a backrest 218, and the like.

The saddle 216 is fixed to the lower body driving unit 211 does not move, the backrest 218 in the saddle 216 supports the back and waist to prevent injuries during exercise to apply force.

The exercise load control device 230 is connected to the upper body driving units 201a and 201b and the lower body driving unit 211 to control the exercise load during exercise of the user. The first rotational exercise element 231 and the second rotational exercise element 232, the third rotary motion element 233, and the instrument control unit 235.

The rotary motion elements 231, 232, and 233 are rotatable elements, for example, high performance motors that operate electronically.

Referring to FIG. 3, the rotary motion elements 231, 232, and 233 are made up of a body member 300 and a shaft member 302.

The shaft member 302 is rotated under the control of the instrument control unit 235 while being inserted into the body member 300.

In the case of the first rotary motion element 231 and the second rotary motion element 232, a force transmission unit 304 may be formed to be connected to the interruption of the shaft member 302, and the force transmission unit 304 and the connection member may be formed. The rotational force of the shaft member 302 can be transmitted to the connecting member through the connection of the 204a and 204b. At this time, the force transmission unit 304 may be a pulley (pulley) that is connected to the end of the shaft member 302, the connection member 204a, 204b may be wound around the pulley and fixed.

In the case of the third rotational motion element 233, the shaft member 302 may be directly connected to the rotation part 215, or the shaft member 302 may be the rotation part 215. Therefore, the rotating part 215 also rotates with the rotation of the shaft member 302.

First, referring to the operation principle of the upper body driving unit 201a, 201b, the rotational force according to the rotational motion of the first and second rotational motion elements 231, 232 is applied to the handles 206a, 206b through the connecting members 204a, 204b. Or external force exerted by the user on the handles 206a and 206b through the connecting members 204a and 204b to the first and second rotary motion elements 231 and 232.

More specifically, the user may provide external force to the rotary motion elements 231 and 232 through the connecting members 204a and 204b by pulling the handles 206a and 206b away from the rotary motion elements 231 and 232. . At this time, the rotary motion elements 231 and 232 provide the handles 206a and 206b with a rotational force in a direction opposite to the external force to provide a load to the handles 206a and 206b. Therefore, when an external force greater than the rotational force of the rotary motion elements 231 and 232 is applied, the handles 206a and 206b are pulled away from the load control device.

Upper body driving unit 201a, 201b of the present invention is composed of a plurality, it is connected to the first rotary motion element 231 and the second rotary motion element 232, respectively. Therefore, it is possible to provide different loads on the left and right sides of the upper body, thereby eliminating the imbalance of the left and right muscle strength of the upper body.

Next, the operation principle of the lower body driving unit 211 will be described.

A rotating part 215, for example a ball screw, for converting the rotation of the third rotary motion element 233 into a straight line is connected to the driving foot 214 via a nut 217. Drive footrest 214 moves forward or backward while supporting nut 217. A user applies a force to the driving scaffold 214 to transmit a force to the third rotational motion element 233 through the rotation part 215, or to transmit the rotational force of the third rotational motion element 233 through the rotation part 215. Forward to 211.

According to the exemplary embodiment of the present invention, the rotating part 215 is connected to the third rotary motion element 233 and rotates in response to the rotation of the third rotary motion element 233. When the rotating part 215 rotates, the nut 217 moves forward or backward according to the rotation direction of the third rotary motion element 233.

The instrument controller 235 is a device for controlling the rotational motion of the rotational motion elements 231, 232, and 233, for example, according to a user's motion, for example, a first current sensing unit of the rotational motion elements 231, 232, and 233. 306 to rotate the rotary motion elements 231, 232, and 233. Here, the first detection unit 306 is a device for detecting the torque according to the rotation of the rotary motion elements 231, 232, 233, for example, the position, speed and torque of the rotary motion elements 231, 232, 233. It may be made of a position speed sensor for detecting.

This position speed sensor 306 is mounted to the rotary motion elements 231, 232, 233 as shown in FIG. 3, and according to the command of the instrument control unit 235, ie, using the current provided from the instrument control unit 235. To rotate the rotary motion elements 231, 232, and 233. Thus, the position speed sensor 306 can detect the torque of the rotary motion elements 231, 232, 233 through the provided current. However, the above method of measuring the rotational torque of the rotary motion elements 231, 232, 233 using the position speed sensor 306 does not directly detect the rotation of the rotary motion elements 231, 232, 233. This may lower the detection accuracy.

Therefore, according to an embodiment of the present invention, as shown in FIG. 3, the second sensing unit 308, for example, a torque sensor, may be further formed on the shaft member of the rotary motion elements 231, 232, and 233. have. As a result, the torque sensor 308 may directly detect the rotational speed of the shaft member when the shaft member rotates to more accurately detect the rotational torque of the rotary motion elements (231, 232, 233).

In addition, the instrument controller 235 receives a torque value corresponding to the rotation of the rotary motion elements 231, 232, and 233 from the sensing units 306 and 308 to measure the amount of exercise.

The instrument control unit 235 may adjust the motion trajectory of the upper body lower body of the user. An operating range of the upper body or the lower body can be set for each user, and when the user's movement range is out of the operating range, the movement trajectory of the upper body of the user is adjusted by stopping the rotation of the rotary motion elements 231, 232, and 233.

The display unit 240 displays various modes so that a user who uses the rowing exercise apparatus 200 can select a specific mode, and displays an exercise amount, muscle strength, etc. measured by the instrument control unit 235. Of course, the display unit 240 may display various contents such as torque, speed, repetition number, and set number according to the user's or designer's setting as well as the exercise amount and muscle strength. That is, the display unit 240 may display various modes and measurement parameters according to a user's setting, and thus, it will be apparent to those skilled in the art that various modifications of these variables do not affect the scope of the present invention. would.

In addition, the display unit 240 may operate by using an external means such as a remote controller, a key button, or may operate in a touch screen manner.

The card recognition unit 242 is a part for recognizing a user, and generally, a personal card of the user is inserted and recognized. However, the rowing exercise apparatus 200 of the present invention may recognize the user by using a number input method through the display unit 240 as well as a method of recognizing the user by a card method.

The support part 244 supports the display part 240 and may fix the handles 206a and 206b.

4 is a block diagram illustrating an instrument control unit according to an embodiment of the present invention.

Referring to FIG. 4, the instrument controller 235 includes a controller 400, a mode unit 402, a drive controller 404, a measurement unit 406, and a memory 408.

The mode unit 402 is a part for controlling an operation related to the exercise mode, and provides the modes to the user through the display unit.

The drive controller 404 controls the rotational motion of the rotary motion devices 231, 232, and 233 to rotate in accordance with the selected mode.

The measurement unit 406 measures the rotational force or the rotational speed related to the torque or torque of the rotational motion elements 231, 232, and 233 when the rotational motion elements 231, 232, and 233 rotate in response to the selected mode. The amount of exercise and maximum muscle strength, etc. are detected. It also measures the user's operating range angle.

For example, when the driving controller controls the driving of the rotary motion elements 231, 232, and 233 by using a current, the measurement unit 406 measures and analyzes an amount of current corresponding to the rotational force or rotational speed related to the torque. The amount of exercise of the user can be detected.

The memory 408 stores a record of individual maximum muscle strength and daily exercise amount. The card recognition unit 242 may classify users and store individual records.

The controller 400 controls the overall operation of the components of the instrument controller 235.

When the pulling force of the user is removed from the conventional exercise device for pulling the weight using the cable or belt, the tension is maintained constant in the direction of gravity by the weight. However, in the case of providing a load by using the rotary motion element as in the present invention, if the user does not abruptly force in the direction of pulling the cable, the tension may be difficult to maintain and the cable or the belt may sag.

According to one embodiment of the present invention, the exercise load control device 230 may further include a tension maintaining unit for maintaining the tension of the connecting members (204a, 204b).

5 is a perspective view showing a rowing exercise mechanism including a tension retaining unit according to an embodiment of the present invention, Figures 6 to 7 shows a load control device including a tension retaining unit according to a preferred embodiment of the present invention Perspective view.

6 (a) and 7 (a) are perspective views of the load control device 100 viewed from one side, and FIGS. 6 (b) and 7 (b) are load control devices 100 viewed from another side. Perspective view.

5 to 7, a first auxiliary roller 603 for supporting the connecting members 204a and 204b may be additionally connected to the connecting members 204a and 204b when the connecting members 204a and 204b move. .

The tension holder 620 controls the movement of the tension adjusting member 621 and the tension adjusting member 621 that move in response to the external force acting on the connecting members 204a and 204b to tension the connecting members 204a and 204b. It may include an elastic member 623 to adjust and the rail portion 625 to move the tension member.

In one example, the tension adjusting member 621 is a roller, the roller can be rotated along the rail portion 625 corresponding to the external force acting on the connecting members (204a, 204b).

More specifically, the tension adjusting member 621 may have a form in which the first roller 621A and the second roller 621B are combined, and the first roller 621A and the second roller 621B may be rail parts 625. It may be coupled to each other by the fixing member 621C movable along.

When an external force acts on the connecting members 204a and 204b in a direction opposite to the direction in which the first and second rotary motion elements 231 and 232 rotate, for example, the connecting members 204a and 204b are formed by the first and second rotational motion elements 231 and 232. When pulled in the direction away from the two rotary motion elements 231, 232, the tension adjusting member 621 moves in the direction in which the tension of the elastic member 623 increases.

On the contrary, when the external force acting on the connecting members 204a and 204b is removed, the tension adjusting member 621 moves in the direction in which the increased tension of the elastic member 623 decreases.

For example, when the first external force greater than the rotational force acts on the connecting members 204a and 204b in the opposite directions of rotation of the first and second rotational motion elements 231 and 232, the tension adjusting member 621 located below as shown in FIG. 7. ) Is moved upward along the rail 625 by the connecting members 204a and 204b. That is, since the connecting members 204a and 204b surround the lower part of the first roller 621A, the first roller 621A is subjected to an upward direction by the first external force acting on the connecting member. Since the second roller 621B is coupled to the first roller 621A through the fixing member 621C that is movable along the rail portion 625, the second roller 621B is also raised together with the first roller 621A. To the side.

In this case, the elastic member 623 surrounding the upper portion of the second roller 621B increases as the second roller 621B moves upward, thereby increasing the tension of the elastic member 623. That is, an external force by the elastic member 623 smaller than the first external force provided by the user to the connection member 101 acts on the tension adjusting member 621.

Subsequently, when the first external force acting on the connecting members 204a and 204b is removed while the tension holder 621 is positioned upward, as shown in FIG. 6, the tension is adjusted by the restoring force of the elastic member 623. The member 621 moves downward as shown in FIG. 7. In this case, the tension adjusting member 623 moves downward to pull the connecting members 204a and 204b so that the tension of the connecting members 204a and 204b is maintained taut.

The second auxiliary roller 627 may be additionally connected to the elastic member 623 in order to reduce friction when the tension member increases or decreases the tension.

In addition, the position and structure of the tension adjusting member 621 and the elastic member 623 shown in Figs. 5 to 7 can be variously modified as long as it can maintain the tension of the connecting member 204a, 204b. It will be obvious to you.

8 is a flowchart illustrating an operation process of the rowing exercise device according to the rowing exercise mode according to an exemplary embodiment of the present invention.

Referring to FIG. 8, the user selects a rowing exercise mode among exercise modes (S801).

Next, the lower body relaxation step is performed (S803). In the case of the lower body relaxation step, the upper body driving unit 201 is fixed, and as the user exerts a force on the driving footrest 214 of the lower body driving part 211, the driving footrest 214 moves forward and the third rotary motion element 233 moves forward. Rotate about the direction.

According to an embodiment of the present invention, the rotational force acting on the third rotary motion element 233 may be kept constant while the user exerts a force on the driving footrest 214 (isometric motion), and thus is applied by the user. The rotational speed of the third rotary motion element 233 changes according to the force.

According to another embodiment of the present invention, the rotational speed on the third rotary motion element 233 may be constant while the user exerts a force on the driving footrest 214 (constant motion). That is, when a force applied by the user to the driving scaffold 214 attempts to increase the rotation speed, a force opposite to the force acts on the third rotational motion element 233. Therefore, the rotational force acting on the third rotary motion element 233 is changed according to the user's force.

The lower body exercise is performed by the user resisting the exercise load generated by the rotational force of the third rotary motion element 233 and advancing the driving footrest 214.

In this case, the advance range of the driving scaffold 214 may be limited to a predetermined operating range for each user, and when the driving scaffold 214 is advanced to a predetermined operating range by the user, the third rotation may be performed by the mechanism controller 235. The rotation of the moving element 233 may be stopped to limit the forward movement of the driving scaffold 214. As a result, each user may have a different lower body locus.

According to another embodiment of the present invention, when the user advances the driving scaffold 214 measures the force exerted by the user on the driving scaffold 214 while moving forward, and the lower body force exerted by the user on the driving scaffold 214 is a preset value. When falling below, the rotational motion of the third rotary motion element 233 may be changed so that the movement of the driving scaffold 214 is automatically stopped.

When the lower body relaxes in the preset range, the drive control unit 404 automatically switches to the upper body relaxing step S805.

In the case of the upper body relaxation step, the lower body is fixed while the driving footrest 214 is advanced to a predetermined range to support the relaxation of the upper body.

When the user pulls the handles 206a and 206b, the force transmission unit 304 rotates and the first and second rotary motion elements 231 and 232 connected to the force transmission unit 304 are pulled by the handles 206a and 206b. Lost in the opposite direction.

In the case of the first and second rotational motion elements 231 and 232, the rotational force may be constant or the rotational speed may be constant as in the third rotational motion element 233 described above.

The upper body movement is performed by a pulling force of the handles 206a and 206b of the user that resist the movement load generated by the rotational force of the first and second rotational movement elements 231 and 232.

In this case, the range in which the user can pull the handles 206a and 206b may be limited to a preset operating range for each user, and the mechanism control unit 235 when the handles 206a and 206b are pulled by the user to the preset operating range. The rotation of the first and second rotational motion elements 231 and 232 may be stopped to limit the movement of the handles 206a and 206b. As a result, different users may have different upper body motion trajectories.

In addition, according to the present invention, a plurality of upper body driving units 201a and 201b for forming the upper and lower sides of the upper body may be set differently with respect to the upper and lower sides of the upper body. Therefore, it is possible to have different movement trajectories suitable for the muscular strength of the upper and left sides of the upper body.

According to another embodiment of the present invention, when the user pulls the handles 206a and 206b, the force transmitted to the handles 206a and 206b is measured, and the force transmitted to the handles 206a and 206b is equal to or less than a preset value. When dropped, the rotational motion of the first and second rotational motion elements 231 and 232 may be changed so that the movement of the handles 206a and 206b is automatically stopped.

In this operation, unlike the existing rowing exercise equipment, the saddle 216 is fixed so as not to move while maintaining the posture of the back by the backrest 218 to prevent injuries of the back such as a disc. In addition, the saddle 216 is fixed to prevent the lower limbs from causing dizziness during the rowing movement.

When the upper body relaxation is completed, the drive control unit 404 automatically switches to the upper body return step.

The upper body return step is performed (S807). In the upper body return step, the first and second rotary motion elements 231 and 232 rotate to return to the initial position before the upper body is relaxed. At this time, the force and the speed of the returning body are appropriately controlled so that the waist is not overwhelmed. When the upper body return is completed to the set range, it is automatically switched to the lower body return step (S809).

The return of the lower body returns to the initial position by the rotation of the third rotary motion element 233. When the lower body return is completed, the exercise is completed once, and the exercise of the four steps is performed once, and the exercise is performed a predetermined number of times.

The user of the rowing exercise apparatus 200 may separately exercise the upper body and the lower body in addition to the motion of the four steps during the rowing exercise.

9 is a flowchart illustrating an operation process of the rowing exercise device according to the operation range measurement mode according to an exemplary embodiment of the present invention.

Referring to FIG. 9, the user selects an operation range measurement mode among exercise modes (S901).

The initial position of the upper body is measured (S903). In the initial position measurement of the upper body, the user applies the force to the connecting members 204a and 204b while the first and second rotational motion elements 231 and 232 maintain the starting position with a light rotational force, and the initial position posture for a predetermined time. When maintaining, the measurement unit 406 measures the angle of the corresponding position and stores the angle of the initial position in the memory 408.

Next, the relaxation position of the upper body is measured (S905). When the initial position measurement is completed, the user applies a force to the connecting members 204a and 204b to maintain the posture of the maximum relaxation position at which the connecting members 204a and 204b are pulled to the body for a predetermined time. The angle is measured and the angle of the relaxation position is stored in the memory 408.

Next, the operating range of the upper body is measured (S907). The operating position is set using the measured initial position and the relaxed position of the upper body, and the driving controller 404 controls the rotation so that the first and second rotary motion elements 231 and 232 can operate within the operating range. .

The initial position of the lower body is measured (S909). In the case of initial position measurement of the lower body, when the user maintains the initial position posture for a predetermined time by applying force to the driving footrest 214 while the third rotary motion element 233 maintains the starting position with a light rotational force, the measurement unit 406 ) Measures the angle of the corresponding position and stores the angle of the initial position in the memory 408.

The relaxation position of the lower body is measured (S911). When the initial position measurement is completed, when the user applies the force to the driving footrest 204 and maintains the posture of the maximum relaxation position at which the driving footrest 214 is fully advanced for a predetermined time, the measuring unit 406 measures the angle of the corresponding position. Thus, the angle of the relaxation position is stored in the memory 408.

The operating range of the lower body is measured (S913). The operating position is set using the measured initial position and the relaxed position of the lower body, and the driving controller 404 controls the rotation to allow the third rotary motion element 233 to operate within the operating range.

10 is a flowchart illustrating an operation process of the rowing exercise device according to the maximum muscle strength measurement mode according to an embodiment of the present invention.

The maximum strength measurement is to measure the maximum force that the user can apply within the operating range when the movement range measurement is completed.

Referring to FIG. 10, a user selects a maximum strength measurement mode among exercise modes (S1001).

Subsequently, the first and second rotational motion elements 231 and 232 rotate in the direction in which the connecting members 204a and 204b are pulled to the first and second rotational motion elements 231 and 232 according to the selection of the maximum strength measurement mode. (S1003). Therefore, when the user does not apply force, the handles 206a and 206b are forced in a direction away from the body.

Subsequently, the user starts the upper body relaxation exercise with his / her maximum muscle strength, in which case the first and second rotary motion elements 231, 232 rotate at a constant rotational speed during the upper body relaxation motion, ie the user's force In the case of increasing the rotational speed, forces in opposite directions act on the first and second rotational motion elements 231 and 232. Therefore, the rotational force acting on the first and second rotational motion elements 231 and 232 is changed according to the force of the user.

Then, the measuring unit 406 measures the changed rotational force (S1005) to measure the maximum muscle strength of the upper body in the upper body relaxation exercise (S1007).

After measuring the maximum strength of the upper body, the maximum strength of the lower body is measured. The third rotary motion element 233 rotates in the opposite direction in which the driving step 214 moves forward. Therefore, when the user does not apply the force, the driving footrest 214 receives a force in the reverse direction.

Subsequently, the user starts the lower body relaxation exercise with his / her maximum muscle strength, in which case the third rotary motion element 233 rotates at a constant rotational speed during the lower body relaxation motion, and according to the user's force, the third rotary motion element The rotational force acting on 233 is changed.

Then, the measuring unit 406 measures the rotational force of the changed third rotary motion element 233 (S1011) to measure the maximum muscle strength of the lower body in the lower body relaxation (S1013).

In the measurement of the maximum strength, a graph of the force according to the motion trajectory can be obtained. By using the graph, it is possible to analyze not only the maximum strength but also the physical condition such as an injury or a physical imbalance.

In addition, by independently driving the upper body and the lower body can be utilized for body correction and injury overcoming by appropriately adjusting the amount of exercise through independent sensors. Separate sensors (not shown) are provided on the left and right side to show the user the imbalance of the force on the left and right, and the user can check the correction and adjust the force on the left and right to improve the imbalance correction and balance ability. Can lead naturally during exercise.

In addition, in order to maximize the effect of the exercise according to the user's fitness and exercise purpose, the amount of exercise can be automatically set by the network and the data about the result can be stored and managed. Although not shown in the drawings, the rowing exercise apparatus 200 of the present invention may be connected to an external management device (not shown) through a wired or wireless communication network. In this case, the individual record measured by the rowing exercise equipment 200 is stored in the management device, and the administrator may manage the user with an exercise program suitable for the individual through the individual record.

According to another embodiment of the present invention, the rowing exercise device 200 may be connected to an external computer (not shown). For example, when the screen displayed on the display unit 240 of the rowing exercise equipment 200 is small and fine adjustment is difficult, the rehabilitation and exercise equipment program may be finely adjusted through the screen of the computer.
