Abstract

The present invention comprises an upper body support member (110) that supports the back or shoulders of an exerciser, a lower body support member (606) that allows the user to exercise the lower body by applying force to the legs while the user supports the upper body on the upper body support member, and a footrest (100) that the user presses with their foot (150) on the lower body support member (606). The user exercises while applying pressure to the footrest and changing the distance between the upper body support member and the lower body support member. The invention is further provided with a load means that restricts the movement of the upper body support member or the lower body support member, and a load adjustment member (405) that controls the load of the load means. The load adjustment member (405) controls the load of the load means to allow the user to perform lower body exercises. In addition, the load means in the present invention comprises a motor (650), a first rotating body (630) connected to the shaft (653) of the motor, and a belt (623) having one side wound around or unwound from the first rotating body according to the rotation of the motor, wherein the other side of the belt is pulled or pushed according to the movement of the upper body support or the lower body support, and the first rotating body rotates due to the pulling or pushing of the belt, and a load is generated on the movement of the upper body support or the lower body support by a motor arranged to obstruct the rotation of the first rotating body, thereby enabling the user to perform exercise.

Description

Lower body exercise equipment with adaptive load The present invention relates to a lower body exercise machine that applies an adaptive load capable of adjusting the exercise load regardless of the actual exercise weight, and more specifically, to a lower body exercise machine with an adaptive control method that allows the exercise load to be adjusted in a soft manner during lower body exercise. Recently, healthcare systems are gaining prominence that provide personalized fitness and exercise management, as well as health care. These systems utilize exercise equipment and fitness measurement devices equipped for personal dietary improvement, basic physical fitness, and health management. Based on fitness measurement data collected while exercising, they gather individual exercise volume, fitness level, and exercise information. By using this collected data to check the individual's exercise volume, fitness level, suitability of exercises, and areas requiring further exercise, they offer personalized fitness and exercise management. As prior art related to this, Patent Registration No. 10-2269255 has registered a "health fitness element integrated measurement device." Figure 1a is a conceptual diagram of a conventional health fitness element integrated measurement device. Figure 1b is a configuration diagram of the health fitness element integrated measurement device of Figure 1a. A health-related fitness element integrated measurement device is disclosed, comprising: a user seating means (100-1) that allows a person to sit and measure health-related fitness elements; a health-related fitness measurement means (200-1) that measures the health-related fitness elements of a person seated on the user seating means (100); a measurement information output means (300-1) that outputs the measurement process and results of the person's health-related fitness elements measured through the health-related fitness measurement means (200-1) in real time so that the person and manager can monitor them; and a measurement control unit (400-1) that controls the user seating means (100-1), the health-related fitness measurement means (200-1), and the measurement information output means (300-1). This allows multiple health-related fitness elements of a person to be easily measured in a single device without the person moving or exchanging measuring devices. However, these exercise machines have the problem that in order to change the exercise load, heavy weights must be attached to and detached from the machine, and the exercise weight to be exercised cannot be finely controlled. In addition, since the exercise weight cannot be changed once determined, there is a problem in that it is difficult to adjust the weight during the workout, even if one wants to exercise more precisely by changing the weight. Furthermore, exercise machines that perform lower body exercises using the left and right feet have a problem in that they cannot accurately measure the load applied to each foot individually because they measure the combined exercise load applied to the left and right feet rather than accurately measuring the actual exercise load applied to each foot. Therefore, when the load applied to the left and right feet differs, physical imbalance leads to problems where physical development is hindered even with vigorous exercise; thus, there is a need for a system capable of accurately measuring the exercise load applied to the left and right feet. Figure 1a is a conceptual diagram of a conventional health fitness element integrated measurement device. Figure 1b is a configuration diagram of the health fitness element integrated measurement device of Figure 1a. Figure 2 illustrates a form in which an upper body support part is positioned at the bottom in the lower body exercise device of the present invention. Figure 3 illustrates the state in which the upper body support part of the lower body exercise device of the present invention is moved upward. FIG. 4 is a plan view of a lower limb exercise load measuring device according to the present invention. FIG. 5 is a cross-sectional view of a lower limb exercise load measuring device according to the present invention. FIG. 6 is a block diagram illustrating an embodiment of the present invention. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings, including the structure and operation of the invention. The present invention is not limited to the disclosed embodiments and may be implemented in various different forms by those skilled in the art. In the description of the present invention, detailed descriptions of related known technologies or configurations are omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the invention.
