Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring apparatus and a weight stack machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for monitoring a general weight stack machine exercise machine using gravity, and more particularly to an apparatus, system, and method for collecting, recording, and displaying information related to a weight stack machine.

In recent years, with the increase of social interest in well-being and health, we are entering into a healthy 100-year-old age. Especially, people who are doing health training as a part of making a healthy body are increasing rapidly.

Among them, a weight training (or weight stack) exercise is widely used in a muscle training apparatus to strengthen the strength.

There are many types of weight lifting devices in weight lifting devices. Gravity is usually used as a load source for typical weight lifting devices. Simple mechanical coupling with devices such as pulleys, levers, wheels, It changes the mechanical merit of all related weight machines, allowing the person using the machine to perform the load motion. Devices made by conventional weight stacking machines, for example, Cybex or Nautilus, include rods pulled up vertically to a rectangular weight plate. The lift bar is pulled up and has a plurality of holes through which the shaft of the pin can be inserted. At the bottom of each rectangular weighing plate there is a through passage (or a hole in the center) through which the pin shaft can pass and is aligned with the hole of the lift bar when the lift bar is in a low position or in a non-use position. To lift the selected number of weight plates, the user inserts the pins into the selected holes in the through-pass and lift bars. When the athlete exercises, the lift bar is lifted and the pin is lifted up together with all weight bars stacked thereon. The various settings of the weight mechanism allow the user to select different loads in the same motion range (ROM) and simply move the various movements by inserting the pins into the lift bar at the desired weight level. Conventional weighting pins usually use steel or other strong metal shafts. In the simplest form, the handle is curved except for the rod portion to be inserted, so that the handle can be easily inserted and removed to facilitate insertion and removal of the pin on the weight plate. Other types of pins may use a plastic handle.

On the other hand, Japanese Patent Application Laid-Open No. 2011-0066432 is disclosed as a fitness apparatus related to weight training.

Although the disclosed patent has an advantage of being able to analyze user information and exercise information, the concept of accurately measuring the position, movement frequency and speed of the weight plate is not disclosed, And can not be analyzed.

As another example, Patent Publication No. 2010-0026062 is disclosed.

The disclosed patent discloses that when a pin is inserted into a weight plate, a high-brightness LED is mounted inside the pin, and the position of the set pin is displayed to the user, thereby detecting the motion state and the number of exercises. It has the advantage of measuring and adjusting the weight.

However, the above patent also has a technical limitation because it has a complicated structure and lacks means for accurately measuring, analyzing and monitoring the user's own strength motion according to the weight of the weight plate and the number of exercises.

As another example, U.S. Patent No. 3,337,365 B2 is disclosed.

In the disclosed patent, when inserting a weight selection pin into a weight stack, a load cell capable of sensing a weight is attached to an insertion rod connected to a pin, thereby detecting the weight of the selected weight and detecting the number of times. However, it is inconvenient to determine the number of times the exercise is performed by not only sensing the weight of the heavy object by the power of the exerciser while performing the exercise, but also analyzing the numerical value of the exercise number and the acceleration sensor simultaneously with the weight detection sensor And the built-in small-size weight sensor must continuously push and pull a large-sized heavy object, and when it is pulled out, it must be exposed to severe impact frequently, so that there is a problem that it exposes a serious problem to durability.

As shown in FIG. 1, the method and apparatus for monitoring a weight stack machine exercise machine according to the present invention directly includes a basic configuration of a well-known weight stacking machine. 2 is a view for explaining a basic configuration of a monitoring method and apparatus for a weight stack machine exercise machine according to the present invention.

That is, it includes a fixed base 100 as a basic structure.

The fixed base 100 is a plate-shaped member and is provided on the ground or the floor surface.

At this time, it is preferable that the fixing base 100 accurately maintains the horizontal state, which is a basic condition required for accurately measuring the momentum.

On the upper surface of the fixed base 100, a pair of fixed guides 40 having a round bar shape is provided.

The fixed guide 40 is a kind of guide which is integrally fixed to the upper surface of the fixed base 100 and holds a plurality of weight plates 20 stacked so as to prevent the weight plates 20 from being shaken or separated.

In other words, the weight plates 20 are formed in a number of, for example, 5 kg or 10 kg by weight, and guide holes (not numbered) are formed on both sides of the weight plate 20, And is stacked in the height direction by being inserted into the fixed guide 40. [

In addition, a hole is formed at the center of the length of the weight plate 20, which is a hole into which the lifting rod 32 shown in FIG. 1 is fitted.

In addition, a pin hole 60 is formed on one side of the weight plate 20, for example, on the front surface of the graphene.

The pin hole 60 is a portion in which the fixing pin 10 for adjusting the weight of the weight plate 20 is inserted and the elevating rod 32 is also lifted and lowered by the lifting rod corresponding to the pin hole 60 of the weight plate Since the rod hole 31 is formed and the fixing pin 10 is inserted through the elevating rod hole 31 formed in the pin hole 60 and the lifting rod 32, After the calculation, the fixing pin 10 is inserted into the pin hole 60 at an appropriate position, so that the weight to be lifted during exercise can be determined. Also, at this time, the LF tag 70 having a unique ID embedded in each of the weight plates in the vicinity of the pin hole 60 is detected by the antenna coil in the fixing pin 10 to check the position of the pin I will.

The fixing block 30 is mounted on the upper surface of the uppermost one of the weight plates 20. The elevating rod 32 is integrally fixed to the lower surface of the fixing block 30, As described above, the weight plates 20 are held vertically penetratingly.

A center of the upper surface of the fixed block 30 is connected to a wire 50 so that the weight plate 20 can be lifted via a pulley when a user grips a handle (not shown) And guide rods 40 are provided on both sides of the wire 50 so that the weight plates 20 including the fixing block 30 can be smoothly moved from the fixed position So that it can be lowered.

Such a configuration is a basic configuration included in a conventional weight training machine.

The present invention comprises, in addition to the weight pin 10 of this general construction, another weight pin according to the invention in the configuration shown in FIG. The weight pin according to the present invention will be described with reference to FIG.

FIG. 3 is a cross-sectional view showing a state in which a weight pin is inserted into one weight plate in a weight plate in the monitoring apparatus of a weight stack machine exercise machine according to the present invention.

When the weight pins are inserted into the weight plate holes 60 and the elevating rod holes 31 to be set, the shaft 14 of the fixing pins passes through the two holes and is fastened to each other. Therefore, The weight to be lifted during exercise can be determined by inserting the fixing pin 10 into the weight plate pin hole 60 at an appropriate position. At this time, the LF tag 70, which is embedded in a line close to the weight plate pin hole 60 and has a unique ID, is detected by the antenna coil 11 in the fixing pin 10 to confirm the position of the pin The position information of the fixing pin is transmitted to the microprocessor of the control unit. The control unit is a kind of CPU having functions of storing, updating, and calculating information.

In addition, the display unit 12 may be further connected to the control unit. The display unit 12 may be installed on the front surface of the fixing pin, or may be installed at a position where the user can see the most comfortable state when the user exercises. And so on.

In addition, the control unit may include a memory as a storage space itself, but a database server (DB) can be further connected for systematic and large-capacity information management.

In addition, the user may measure the amount of exercise based on the information obtained through the three-axis acceleration sensor described later, and if necessary, install and use the corresponding application to be directly transmitted to the user's PC or smart phone, A wireless communication unit (not shown) and an internal power supply unit 13 may be further provided in the exercise machine of the present invention.

Meanwhile, the fixing pin 10 is provided with an acceleration sensor, and the acceleration sensor is connected to the control unit.

The acceleration sensor is a sensor means for sensing the height of the weight plate, the number of motions, the speed of motion, etc. Since the distance (position) and the physical quantities of speed and acceleration are in a non-integral relation with respect to time, Knowing the information allows you to calculate other information in a computational way.

For example, if the velocity is differentiated by time, it becomes acceleration. When the acceleration is integrated with respect to time, it becomes a velocity.

Therefore, it is possible to obtain the velocity by knowing the initial velocity, then continuously measuring the acceleration, and integrating the acceleration with respect to time, and the position can be known by integrating the velocity.

That is, the initial position at which the weight plate 20 is fixed in the state where the exercise device is not moved becomes the integral constant, and when the acceleration is continuously measured, the change of the speed is continuously known, and the weight plate 20 is integrated So that the user can know the location where the user is located.

Particularly, the acceleration sensor can detect the recoil which occurs when the weight plate 20 rises and collides with the lower weight plate while descending, so that more accurate sensing is possible and the accurate acceleration can be detected .

Further, when the uppermost portion of the weight plate 20 is lifted up to a predetermined height by setting a constant height and a fixed speed from the weight plate 20, and when the weight plate is lifted and lowered at a correct speed, And adds the number of times.

FIG. 4 schematically depicted for this purpose is a diagram illustrating a method for monitoring movement of a weight stack machine according to the present invention, and a method for implementing the number of times and the execution speed of the apparatus.

Accordingly, Figure A is a diagram showing the motion once, and Figure B is a diagram showing signals of the three-axis acceleration sensor generated at this time. In the figure, t represents the movement time, g represents the acceleration of gravity, l represents the distance of motion, and r represents the deviation, which is the ideal range of motion based on the ROM (range of motion) lc) and the actual practice exercise distance (la) based on the actual exercise ROM based on the exercise practitioner's information. This information will monitor the actual number and speed of exercise.

FIG. 5 is a flowchart showing a method and an apparatus for monitoring a motion of a weight stacking machine according to the present invention.

Usually, the weight stack machine's movement does not stop with just one or two movements. It is usually a group of five to several dozen kinds of athletic apparatus and aims at the movement of each related muscle group of the body. Therefore, the method and apparatus according to the present invention are based on a system integration configuration.
