[0001] FLUID EXERCISE DEVICE WITH PHNEUMATIC WEIGHT [0002]

The present invention relates to a fluid exercise apparatus having an air pressure weight, and more particularly, to a motion force transmitting apparatus for converting a motion force of a user into hydraulic pressure and a motion force adjusting apparatus having a weight for operating a resistance load The present invention is characterized by providing a safe and practical fluid exercise device without any additional weight to improve the strength of the user.

In general, weight training is a representative example of anaerobic exercise, which is muscle strength exercise to develop strong physical strength through muscle development.

Weight training is often referred to as resistance exercise. In other words, as a means of giving a load or resistance to the muscles, the muscular strength is strengthened by using a magnetic body weight or by applying a resistance load to the muscles using a heavy material, a spring, or a band.

For example, a squat, a lunge, a push-up, and the like are representative examples of exercises using magnetic body weight, and they are strength exercises using only their own weight as a load without using any additional weight.

Exercise using heavy objects has free weight training using simple tools such as dumbbells and barbells, and exercise exercises by choosing a weight suitable for your athletic ability.

On the other hand, in recent years, various kinds of professional weight exercise apparatus can be used to effectively improve muscle strength. For example, a weight machine, a smith machine, a cable machine, or the like for mounting a weight block can be used. It is safe and convenient because there is less risk of injuries compared to free weight using heavy material, and most of all, there is an advantage such that only the muscle group can be cautiously strengthened when strengthening the muscle of a specific region.

As an example of the weight machine, a configuration of a technique known in the registered patent No. 10-0757205 will be briefly described as follows.

The weight machine includes a frame and a pulley, and pulls the wire into the lever to lift the weight. The load machine includes a load balancer and a vibrator fixed to the lever, a load balancer fixed to the weight while being connected to the wire, Wherein the load fluctuation device includes a pair of vertical plates having bearings, a pair of vertical plates having integrated rotary shafts, an integrated base plate, a spring fixed to the base plate and the upper plate in a hinged shape, A pair of vertical plates in which the rotary shaft is incorporated, a pair of vertical plates in which the bearings are incorporated, an upper plate integrated with the adjusted weight, a speed reducer fixed to the lower end of the upper plate, A crank that is connected to the reduction gear shaft and has a controllable radius of rotation, a bearing coupled to the rotation shaft, and a connection rod having a bearing coupled with the crank.

The weight block mounted on the weight machine has a structure that can be attached to and detached from the machine for setting and adjusting the intensity of the exercise. For example, a structure of a weight block for a sports machine, which is disclosed in Korean Utility Model Registration No. 20-0368301, is fitted to a guide rod of an exercise machine and is installed so as to move up and down along a position fixing rod formed on a connecting body. A gap holding portion is formed by protruding a part of the upper surface and the bottom surface in a stepwise manner, a guide groove is formed in both sides of the guide groove, and a coupling portion having a predetermined size space is formed between the gap holding portions.

Registration No. 10 - 0757205 (September 11, 2007) Registration Utility Model No. 20 - 0368301 (November 11, 2004) Registration No. 10-0549407 (2006.02.08) Registration No. 10-1441803 (Nov. 31, 2014)

The weight machine to which the conventional technique as described above is applied is such that the wire connected to the lever pulls up or down the weight when the user grasps the lever and pulls or pulls down the lever.

In addition, a weight block (weight weight) used in a weight machine of the prior art is provided to set and adjust the exercise intensity by stacking a plurality of weight blocks on a guide rod connected with a wire.

Such a weight machine generally has a large size and requires a large occupied space, and the cost of the weight machine itself and the costs associated with maintenance are also inconvenient for an individual to bear.

In addition, since the weight block as described above needs to be assembled so as to stack a plurality of weight blocks in a guide rod installed on a frame of the exercise machine by selecting an appropriate weight block according to the user's exercise capacity, And there is a risk of various injuries and accidents during assembly, so care must be taken.

Therefore, it is difficult to install and use a weight machine in a general home. Therefore, a fitness center equipped with various weight machines must be registered to be instructed by a professional trainer, which places a burden on the user.

In the case of free weight training using a simple tool such as a dumbbell, a barbell, or a rubber band, which is commonly used at home, the weight of the heavy object is small, light, safe and inexpensive. However, And it is difficult to operate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure and operation of a fluid exercise device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a fluid exercise device having pneumatic weight according to the present invention, FIG. 2 is a front view of a fluid exercise device having an pneumatic weight according to the present invention, and FIG. FIG. 4 is a side view of the fluid exercise device according to the present invention. FIG. 4 is a side view of the fluid exercise device according to the present invention. FIG. 6 is a side view of the fluid exercise device having the pneumatic weight according to the present invention. The use state according to the embodiment will be described together as an example.

The fluid exercise device including the pneumatic weight weight to which the technique of the present invention is applied includes a motion force transmission device 110 and a motion force control device 120 so as to apply a uniform resistive load to the muscle using the hydraulic pressure and the air pressure It is noted that the present invention relates to a technique for enhancing the strength of the user by exercising the exercise effect safely and effectively while simplifying the structure as compared with the prior art having the complicated structure for mounting the weight block.

As shown in FIG. 1, the fluid exercise apparatus having the pneumatic weight according to the present invention includes a motion force transmitting device 110, a motion force adjusting device 120, and a pressure holding device 130 Specifically, it is as follows.

The motion force transmission device 110 includes a motion bar 111 that reciprocates in response to a user's movement force, a fluid cylinder 112 that receives and seals a predetermined amount of fluid and a fluid cylinder 112 that interlocks with the motion bar 111 112), and a fluid piston (113) which pressurizes the fluid by converting the kinetic force into pressure.

The movement bar 111 directly or indirectly acts on the user's movement force and transmits the motion force to the fluid piston 113.

A predetermined bracket (not shown) is mounted on the end of the movement bar 111. A bracket is connected to a pulley, a wire, a handle, or the like capable of transmitting the movement force of the user in a direction of ascending or descending, or a structure capable of attaching and fitting the exercise device of the present invention to the other exercise device as shown in Fig. 6 do.

The fluid cylinder 112 receives and seals a certain amount of fluid in the internal space. And a fluid piston 113 reciprocating upward and downward in cooperation with the motion bar 111 to convert the motion force into hydraulic pressure.

In the present invention, as shown in the accompanying drawings, the body of the fluid cylinder 112 is made of a transparent material. However, the structure of the fluid cylinder 112 is easy to grasp the internal structure.

The fluid cylinder 112 is provided at the bottom thereof with a pressure transmission pipe 140 to be described later so as to communicate with the gas cylinder 121. An inlet 114 is formed at one side of the upper portion of the pressure transmission pipe 140 so as to communicate with the bypass unit 150. Details of this will be described later.

Meanwhile, the fluid cylinder 112 incorporates return means 115 for returning the position of the fluid piston 113 in the course of extinguishing the movement force transmitted to the fluid piston 113 by the motion bar 111.

The fluid in the fluid cylinder 112 moves in the fluid cylinder 112, the pressure transmission pipe 140, the gas cylinder 121 and the bypass unit 150 according to the state in which the motion force of the user acts, Lt; / RTI >

That is, even if the fluid piston 113 descends due to the action of the user, the fluid piston 113 ascends and returns to the original position due to the hydraulic pressure when the user's movement force disappears. However, when some unavoidable hydraulic pressure loss occurs in the repetitive operation, or in consideration of the amount of fluid bypassed to the bypass portion 150 and the like, the return means 115 may be disposed in the fluid piston 113 So that the fluid piston 113 is given a returning force.

In the preferred embodiment of the present invention, the return means 115 is formed in the form of an elastic spring, but it is natural that the shape thereof can be variously modified.

On the other hand, a motion force adjusting device 120 for imparting a resistance load to a motion force of a user is provided on one side of the motion force transmitting device 110 as described above.

The kinetic energy regulator 120 includes a gas cylinder 121 for receiving and sealing a predetermined amount of gas and a pair of spaced apart gas cylinders 121 for pressurizing the accommodated gas, 122, 123).

The gas cylinder 121 accommodates and seals a predetermined amount of gas, i.e., air, in the internal space. And a weight which is composed of first and second base pistons 122 and 123 that reciprocate upward and downward by the pressure of the fluid flowing through the momentum transmitting device 110 to form a gas pressure.

In the present invention, the body of the gas cylinder 121 is made of a transparent material in the same manner as the fluid cylinder 112, but the structure of the gas cylinder 121 is easy to grasp the internal structure.

The weighing device replaces the function of the weight block mounted on the weight machine of the prior art, but forms the desired level of resistance load by the air pressure, not the weight.

That is, air is accommodated in the space between the first base piston 122 and the second base piston 123. When air pressure is formed in the gas cylinder 121 by the pressure holding device 130 to be described later, a force for expanding the air between the first and second gas pistons 122 and 123 by a compressed volume acts to lower the weight .

A pressure transmission pipe 140 to be described later is provided at the bottom of the gas cylinder 121 so as to communicate with the fluid cylinder 112. A discharge port 124 is provided at one side of the upper part having the pressure transmission pipe 140 So as to communicate with the bypass unit 150. Details of this will be described later.

The pressure holding device 130 provided on the upper side of the kinetic energy adjusting device 120 includes a pressure adjusting bar 131 coupled to the first gas piston 122 of the kinetic energy adjusting device 120, And a fixing panel 132 for fixing the weight to the gas cylinder 121 to maintain the external pressure of the weight.

Accordingly, the user can adjust the air pressure acting on the weight by appropriately raising and lowering the pressure holding device 130 in consideration of the exercise capacity of the user.

The pressure transmission pipe 140 communicating the fluid cylinder 112 and the bottom of the gas cylinder 121 is configured to transmit the fluid pressure generated in the force transmission device 110 to the force control device 120 It is transmitted to the weight and corresponds to the resistance load.

In the present invention, the volume of the fluid cylinder 112 is set to be smaller than the volume of the gas cylinder 121 so that the hydraulic pressure converted by the user's motive force acts on the force transmitting device 110 with a greater force than when acting on the force transmitting device 110. In addition, the fluid cylinder 112 communicating with the pressure transmission pipe 140 and the hole (not shown) provided at the bottom of the gas cylinder 121 are formed to have smaller holes in the gas cylinder 121, So that a pressure due to a large force acts. Since such a configuration is based on Pascal's principle, a detailed description thereof will be omitted.

A bypass unit 150 is connected to the inlet 114 and the outlet 124 formed at a predetermined height on one side of the fluid cylinder 112 and the gas cylinder 121 to be introduced into the gas cylinder 121 To the fluid cylinder (112).

That is, the user's movement force transmitted through the motion force transmitting device 110 acts on the pressure holding device 130 at a pressure greater than the pressure (resistance load) of the gas cylinder 121 set in the kinetic energy adjusting device 120 The fluid moves to the gas cylinder 121 and rises in weight.

Accordingly, the discharge port 124 of the gas cylinder 121 is opened by the rise of the weight, and the fluid is discharged through the bypass unit 150 to maintain the internal pressure of the cylinder.

The bypass unit 150 is provided with a valve block 152 having an operation ball 151 therein so that the flow of the fluid can be moved in one direction only from the gas cylinder 121 to the fluid cylinder 112 .

In addition, the bypass unit 150 is additionally provided with a predetermined overflow tank (not shown) to appropriately adjust the fluid amount.

The state of use of the fluid exercise device having the pneumatic weight weight to which the technique of the present invention having the above-described configuration is applied will be described below.

As shown in FIG. 1, the fluid exercise apparatus having the pneumatic weight according to the present invention may be configured such that a predetermined handle or the like itself is attached to the kinetic energy transmitting device 110 and used, In place of the weight block.

Fig. 4 shows a state in which the kinetic energy of the user is applied to the fluid exercise device of the present invention.

That is, when a motion force is applied to the motion bar 111 of the kinetic energy transmitting device 110 and pressure is applied to the fluid piston 113, the fluid in the fluid cylinder 112 is lowered together with the fluid piston 113.

The fluid is transferred to the pressure transfer tube 140 through the bottom of the fluid cylinder 112 and into the gas cylinder 121 of the kinetic energy regulator 120.

Meanwhile, the weight placed inside the gas cylinder 121 accommodates a certain amount of air in the spaces separated between the first and second gas pistons 122 and 123.

At this time, the user adjusts the position of the fixing panel 132 and the pressure adjusting bar 131 of the pressure holding device 130 provided on the upper side of the kinetic energy adjusting device 120, Thereby creating an appropriate level of atmospheric pressure. Therefore, the air between the first and second gas pistons 122 and 123 acts as an expanding force by a compressed volume, thereby imparting a resistance load in a direction to downward the weight.

Therefore, since the fluid flowing into the gas cylinder 121 through the pressure transmission pipe 140 is subjected to the resistance load by the pressure of the weight, the user can apply the stronger motion force to the force transfer device 110 Efforts should be made.

When the motion force of the user acts more than a predetermined level of air pressure previously set through the pressure holding device 130, the fluid passes through the discharge port 124 provided at one side of the gas cylinder 121, .

The valve block 152 of the bypass unit 150 is provided with an operation ball 151 to bypass the fluid cylinder 112 by opening the passage only when the fluid flows into the bypass unit 150.

Meanwhile, FIG. 5 shows a process in which the kinetic energy is extinguished in the kinetic energy transmitting device 110.

As the fluid bypasses from the gas cylinder 121 to the fluid cylinder 112 through the bypass unit 150, the weight decreases and the fluid piston 113 rises to return to the original position. However, in consideration of the case where some hydraulic pressure is lost during operation or the fluid amount varies through an overflow tank (not shown) provided in the bypass unit 150, The restoring force of the fluid piston 113 is compensated by the resilient restoring force of the spring 115.

Further, in the preferred embodiment of the present invention, the force transmitting device 110 and the kinetic energy adjusting device 120 are 1: 1. However, when a plurality of kinetic energy adjusting devices 120 are connected in parallel, can do. In addition, it is also possible to configure the motion force transmitting device 110 in a bidirectional direction by using a predetermined pulley means to maximize the exercise effect.

The fluid exercise machine having the pneumatic weight according to the present invention has a merit that the structure is greatly simplified compared with the weight machine of the prior art by constituting the fluid exercise machine having the pneumatic weight weight according to the present invention to operate the resistance load using the hydraulic pressure and the air pressure.

In particular, since the weighting function and the excellent operability comparable to the functionality of the conventional weight machine are exhibited without providing a separate weight such as a weight block, the apparatus is economical and practical, and has safety and ease of use.

Therefore, the present invention can be easily carried out in a general household so that weight training can be easily performed. In addition, the present invention can be applied to a variety of other exercise devices to exercise effects in various areas, It is expected.
