BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a muscle force exercise apparatus capable of enhancing a muscle strength of a person, and more particularly, to a muscle force exercise apparatus capable of enhancing muscle strength by controlling the discharge amount of compressed air when the compressed air flows in and out, The present invention relates to a fitness apparatus using air flow control.

In order to strengthen muscle strength, exercise machines that are widely used in weight muscle exercises can be considered.

The weight stack movement is basically a mechanism for laminating steel weight plates having a predetermined weight, adjusting the weight by adjusting the number of stacked steel weight plates, and pulling them to exercise, which is most widely used in general health facilities Is a general strength exercise device.

However, when the exercise device is used by an elderly person, a woman, or a glazier, the fit of the exercise may be a problem due to injuries to the moving parts such as the joints, unreasonable muscle strength resistance, and the weak person's early closure of the growth plate.

For this reason, exercise methods adopted as alternative methods can be exemplified by exercise machines using oil / air pressure.

For example, a hydraulic type exercise machine adjusts the flow amount of a flow in a hydraulic cylinder tube by using an orifice to adjust the exercise intensity of a person who exercises, There is a problem that it depends on the speed of motion rather than strength.

On the other hand, Patent Publication No. 0993985 discloses a pneumatic exercise apparatus (fitness apparatus).

The pneumatic exercise device according to the disclosed patent is advantageous in that it exercises by using compressed air compressed in the cylinder, and thus can exercise properly by adjusting the pressure of the compressed air.

However, since the disclosed patent uses a single-acting pneumatic cylinder structurally, it has a limitation that it can move in only one direction.

Likewise, in Japanese Patent No. 0548084, there is disclosed a fitness machine using pneumatic pressure. In this case, too, pushing and pulling can not be performed at the same time.

Therefore, it is necessary to control the air pressure regulating valve in the direction to move by dividing the operation when pushing and pulling, and then it is necessary to adjust the air pressure regulating valve every time the direction is changed, .

In addition, these exercise apparatuses have a complicated circuit structure for using oil and air pressure, so that they are difficult to design and control, are prone to failure, and are expensive.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, the exercise apparatus using the airflow control according to the present invention includes an apparatus main body 100 used for strength exercise.

The device body 100 may be implemented to support various strength movements.

In this case, the apparatus main body 100 is provided with an exercise lever 110 for performing a muscle force exercise.

The moving lever 110 is hinged at one end to a part of the apparatus main body 100, and the hinge-fixed end adjacent side is hinged to the pneumatic cylinder 120 to provide the user with the necessary load for movement.

The control panel P is provided on the user's front side of the apparatus main body 100 at a position that is convenient for the user to approach the pneumatic cylinder 120. The control panel P is connected to the pneumatic cylinder And a controller (C) capable of controlling the air pressure of the engine.

In this case, a piston (not shown) is installed in the pneumatic cylinder 120 according to a direction in which air pressure is applied. On the outside of the pneumatic cylinder 120, (310, 320, 330).

In particular, the first, second and third position sensing sensors 310, 320, and 330 are electrically connected to the controller C, and sense the position of the piston to transmit a sensing signal.

In this case, the position detecting sensor is merely one example of the three position sensors, and it is needless to say that the position detecting sensor can be installed in a large number of units for more precise and fine adjustment.

An upper speed controller 340 and a lower speed controller 350 are connected to upper and lower ends of the pneumatic cylinder 120, respectively.

Here, the upper speed controller 340 and the lower speed controller 350 are opening regulators for regulating the amount of air to be discharged, and the upward or downward speed of the pistons can be quickly adjusted according to the control of the air amount.

In addition, the upper speed controller 340 and the lower speed controller 350 control the amount of the discharged air, and are free when the air is not discharged.

2, the upper speed controller 340 and the lower speed controller 350 are configured in the same manner. The body 400 has a substantially 'A' shape, An adjustment shaft 410 connected to the opening adjuster (not shown) and exposed to the outside of the body 400, a first and second connectors (not shown) for adjusting the discharge amount of air according to the opening degree of the opening adjuster, 420, 430).

At this time, the first connection port 420 is connected to the upper end or the lower end of the pneumatic cylinder 120, the second connection port 430 is opened to the air, (Not shown) of the lower motor 360 and the lower motor 370, respectively.

The opening regulator incorporated in the body 400 is the same as the structure adopted in a commercially available two-way speed controller, such as an orifice check valve type (a combination of an orifice and a check valve in parallel) When the air flows into the first connection port 420 from the side of the first connection port 420, the check valve and the orifice are both opened, The check valve closes and only the orifice is open, so only a small amount of air can be discharged.

Therefore, if the opening degree of the orifice is adjusted, the air pressure can be adjusted easily and quickly.

In other words, an upper motor 360 and a lower motor 370 are connected to the control shaft 410 of the upper speed controller 340 and the lower speed controller 350, respectively. The upper motor 360 and the lower motor 370 are connected to the controller C and are driven under the control of the controller C, respectively.

3, an upper end pressure sensor 342 and a lower end pressure sensor 352 are installed at the first connection ports 420 of the upper speed controller 340 and the lower speed controller 350, respectively, All of which can be connected to the controller C.

Thus, the controller C senses the exhaust air pressure applied to each of the first connection ports 420, and determines how much load is applied to the controller C, .

Furthermore, a load cell R is further provided on the movement lever 110 to measure an actual load applied when the user lifts or lowers the movement lever 110. The controller C calculates the movement load, And the upper and lower pressure sensors 342 and 352 may be installed in parallel with the load cell R so as to be compared with each other.

As shown in FIG. 4A, when the user lifts the exercise lever 110, the piston is lifted up. The upward movement of the piston causes the third The controller C receives the sensing signal and controls the opening of the upper speed controller 340 by driving the upper motor 360. [ Thereby controlling the air pressure applied to the upper portion of the pneumatic cylinder 120, thereby allowing the user to exercise with a desired motion load.

That is, as shown in the drawing, the discharge air flows out through the upper speed controller 340 by a small amount by the amount adjusted as shown by the broken arrow, and therefore acts as a motion load by the set pressure in the upper side of the pneumatic cylinder 120, The user can exercise the muscles when lifting the exercise lever 110.

At this time, the air (solid arrow) flowing into the lower portion of the pneumatic cylinder 120 through the lower speed controller 350 can freely flow in a large amount, so that the lower space is rapidly filled with the piston rising, Thereby creating a motion load on the lower portion of the body 110 when the body 110 is lowered.

For example, as shown in FIG. 4 (b), when the lifted movement lever 110 is lowered, the first position sensing sensor 310 and the second position sensing sensor 320 are sequentially recognized, The controller C controls the discharge pressure of the discharged air by controlling the opening degree of the lower speed controller 350 by driving the lower stage motor 370, Since the air pressure is controlled, the user can exercise with the desired exercise load.

In other words, as shown in the drawing, the discharge air flows through the lower speed controller 350, and a small amount of the discharge air flows out of the pneumatic cylinder 120, The muscular movement can be performed in the same manner as the above-mentioned raising when the exercise lever 110 is lowered.

As described above, the exercise apparatus according to the present invention can exercise muscles with the same exercise load not only when lifting the exercise lever 110, but also when lifting it.

In addition, since the load is controlled by the pneumatic cylinder 120 using the pneumatic cylinder 120, it is possible to precisely set the exercise load as well as the fine adjustment, thereby maximizing the exercise effect.

In addition, as illustrated in FIG. 1, the control panel P further includes a user recognition unit and a display, which can be connected to the controller C.

At this time, the user recognizing unit recognizes an ID card such as an electronic tag (e.g., RFID) or a commonly used magnetic card, and thereby allows the user's identity to be confirmed.

In this case, if a memory is built in the controller C itself, a plurality of users can be registered and managed even if only the control panel P is provided.

Furthermore, for more systematic management, the controller C may further include a wired / wireless communication unit T, which can be configured to communicate with a management server (not shown) such as a PC in a store.

In this case, it is possible to easily manage the user by registering in the DB through the management server. For example, information necessary for management such as weight, height, body fat, muscle mass, .

In addition, a load cell R may be further provided on the movement lever 110 to provide an amount of exercise suitable for each user. The load cell R may be connected to the controller C and utilized in adjusting the air pressure.

For example, when the user lifts the exercise lever 110 so that a load suitable for the identified user is provided, the controller C, which has received the load sensing amount of the load cell R detected in the current state, The opening degree of the upper speed controller 340 and the lower speed controller 350 is adjusted so that the amount of load applied to the user in comparison with the reasonable load amount is adjusted.

Therefore, the user can secure the most suitable momentum for himself / herself.

In addition, it is preferable that a momentum of the day is displayed on the display provided on the control panel P according to the user's selection.

As described above, the exercise apparatus according to the present invention is expected to provide an efficient and accurate exercise amount, and thus its utilization will be great.
