The present invention relates to a sit-up forward bending measuring device and electronic system for automatically measuring the flexibility of the waist by bending the upper body forward while the arm is extended, and performing the measurement in a sitting position on the floor.

To explain this in more detail, the measuring instrument is installed on the guide plate by bending the waist forward in the state where the arm is extended in the overall state while the sole is placed against the footrest installed vertically between the upper and lower guide plates and the base plate. It is to provide a sit-up and forward bending measuring device and electronic system that digitally displays by measuring the distance of the measuring sphere to be moved by the fingertips by means of detection means consisting of slits and pulse detection interrupts.

In general, when measuring the sit forward bending, it was conventionally performed by bending the body forward while extending the arm while standing on the footrest, and measuring the position of the fingertip with a regular ruler.

As described above, the method of measuring with a ruler while bending the body forward while standing on the scaffold has a problem that the measurement value (scale) is remarkably different depending on the posture of the subject and the position of the measurer. Not only does this occur, there is a problem that cannot be measured accurately because the scale is stretched and changed according to the temperature (climate), and because the body is bent forward while standing on the footrest, there is a problem that the measurement cannot be performed accurately due to unstable posture. .

Although the device for measuring the upper body bending in a sitting position as in the present invention is not known, it is known that a number of height measuring devices are known to be measured using a detection means composed of slits and photocouplers. Utility Model Registration No. 201147 "Height Measurement Device" is known.

It hangs the wire rope between the slits pulley installed at the top and the driving pulley installed at the bottom of the prop, and revolves into the wire rope static area by the motor mounted on the drive pulley. Slit pulley slides up and down along the guide hole, which is perforated in the longitudinal direction on the front side of the support, and a pulse detection interrupt is installed at the periphery of the slit by mounting the slits through which the floodlight is densely perforated in the periphery of the slits pulley. When the wire rope rotates by the operation of the motor and the headboard is downward and the head of the subject is touched and the slits rotate together with the slits pulley, the corresponding pulse is detected by the pulse detection interrupt and counted to the MCU. To be displayed on the display digitally.

As described above, the elongation measuring device using the slits and pulse detection interrupts is fundamentally different from the measurement principle of the upper body bending measuring device and the electronic system according to the present invention, and the elongation measuring device automatically reduces the headboard lowered by the operation of the motor. Since it is a way to touch the head of the subject to be specified while descending, there is a problem that it is not easy to apply to the method of artificially pushing the measurement plate with the fingertips while measuring the subject while bending the upper body as in the present invention.

In other words, if you want to measure while moving the measuring plate automatically, you should move the measuring instrument to the subject with the measuring plate positioned at the tip, but keep the measuring instrument with the body bent forward for a few seconds. Measurements can be made by touching the fingertips by moving to the person's side, but the subject cannot easily maintain the unstable posture for a few seconds, and the measurement is performed in the subject's unsafe posture, so that the measurement can be performed accurately. There will be no.

The present invention is to provide a sit-up forward bending measuring device and electronic system that can solve the above problems.

The present invention bends the measuring instrument installed in the guide plate by bending the waist forward in the state in which the arm is extended in the overall state while sitting on the sole against the footboard installed vertically between the upper and lower guide plates and the base plate. It is an object of the present invention to provide a device for measuring an elbow flexion and an electronic system, which measures the distance of a measuring port moving on a principal surface and displays it digitally by detecting the distance between the slits and the photocoupler.

Another object of the present invention is to sit with the legs stretched forward to measure the arm to the front to perform the measurement to maintain a stable posture, the subject to maintain a stable posture so that the measurement is made accurately It is to provide a forward bending measurement device and an electronic system.

Another object of the present invention, by bending the waist forward in the state in which the arm is extended to the front, pushing the measuring sphere installed on the guide plate with the fingertips, to measure the distance that the measuring sphere is moved, thereby accurately performing the measurement It is to provide a sit-up forward bending measurement device and electronic system that can be made.                         

Another object of the present invention, by excluding the ruler, by measuring by using a detection means consisting of slits and photocouplers, precise measurement is made and the data of the fitness reference table stored in the MCU corresponds to the measured length The present invention provides a sit-up forward bending measurement apparatus and an electronic system in which a determination value is automatically displayed.
