By the way, such a conventional exercise device, by using only the inherent elastic force of the elastic member to give everyone the same athletic ability, such that one person is exercise, but the other rather the body comes to the body The drawback is that adverse effects can only occur.

As one of the other conventional sports equipment, "slide sports equipment" of Korean Utility Registration No. 261703 (2002.1.11) is disclosed. The disclosed slide exercise mechanism is provided with a support plate on the upper rear of the I-shaped floor frame, the inclination adjustment plate is freely installed within a predetermined range in the upper front of the I-shaped floor frame, while the slide plate having a handle on the inclination control plate It is installed to reciprocate in the front and rear direction so that it can be used to train each part of the body such as the arm and abdomen while reciprocating in the front and rear direction.

However, such an exercise device has a problem that the exercise effect is remarkably inferior because the force required to reciprocate the slide plate cannot be adjusted in the process of reciprocating the slide plate.

In addition, Korean Utility Registration No. 265366 (2002.2.7) discloses an exercise equipment for strengthening strength. The disclosed sports equipment includes a support plate, an outer pipe installed vertically on the support plate, an inner pipe inserted from the top of the outer pipe and slidable, and installed between the outer pipe and the inner pipe to resilient the inner pipe relative to the outer pipe.

As shown in these figures, the hydraulic device 100 of the multipurpose exercise device according to the first embodiment of the present invention, the device body 10, the central region is disposed in the device body 10, both ends of the device body An actuating member 40 which is exposed to be exposed from 10 and rotatable in a predetermined angular forward / reverse direction by a wheel 50 (see FIG. 1) or a lever 50 ′ (see FIG. 5) to be described later, and part of the actuating member 40. Piston 20 and a plurality of flow paths (19a) provided in the cylinder 12 to be moved in the longitudinal direction of the apparatus main body 10 to be coupled to the linear movement in the cylinder 12 during the rotational movement of the operation member (40) , 19b) includes a pressure adjusting unit 60 mounted on one side of the apparatus main body 10 to partially open and close the first flow passage 19a to adjust the pressure applied to the operating member 40. At this time, the opening degree of the first passage 19a is controlled by the pressure applied to the apparatus main body 10, which will be described later.

The device body 10 is formed of a metal material having corrosion resistance. Inside the apparatus body 10, a predetermined cylinder 12 filled with oil 11 is formed. The plurality of flow paths 19a and 19b through which the oil 11 moves are formed around the cylinder 12.

In this embodiment, a plurality of flow paths (19a, 19b) is formed along the longitudinal direction of the device body 10, as shown in Figure 3, in communication with the hole 22a formed on the side of the piston 20 is oil The first flow path 19a forming the flow path of (11) and the second flow path 19b for communicating the first flow path 19a and the cylinder 12 will be described. The hole 22a is formed at the end portion of the rack 22 so that the oil 11 filled in the space 21 can move selectively to the first flow passage 19a.

Referring to FIG. 1, at one end of the apparatus body 10, a first fastening portion 14 to which a cap 13 that shields the cylinder 12 is detachably coupled is formed. An airtight O-ring 13a for intercepting the outflow of the oil 11 is interposed between the cap 13 and the first fastening portion 14.

A through hole 15 penetrating the cylinder 12 is formed at a side surface of the apparatus body 10 at a position spaced apart from the first fastening portion 14, and the operation member 40 opens the through hole 15. The shaft support portion 18 is formed with a second fastening portion 17 which is partially inserted into and supported by the apparatus body 10 through the support body 18.

The second fastening portion 17 is coupled to the support cap 16 for rotatably supporting both ends of the operation member 40 while preventing the oil 11 filled in the cylinder 12 from leaking to the outside. At this time, a separate bush bearing 44 is inserted into the support cap 16 to reduce the frictional force generated when the operating member 40 rotates.

The rear surface of the apparatus main body 10 is formed in a flat plate-like body, and fixing holes 10a for fixing the apparatus main body 10 to a predetermined mounting wall surface are formed at both ends of the rear surface. As shown in Figure 2, by inserting a screw 70 or the like in the fixing hole (10a) by fastening to the installation surface (S), such as the bottom surface or wall surface, the hydraulic apparatus 100 can be used anywhere.

On the other hand, between the piston 20 and the cylinder 12 of the apparatus body 10, when the operating member 40 rotates in one direction and moves the piston 20 linearly in one direction, the piston 20 is moved oppositely. The first elastic member 30 of the spring type is elastically urged in the direction. The first elastic member 30 is provided between the piston 13 and the cap 13 screwed to the opening of the cylinder 12 so that the elastic force is always kept pressing the piston 20. do.

The first elastic member 30 rotates the operating member 40 by applying a force for movement, and then elastically expands when the force is released to return the operating member 40 and the piston 20 to their original positions. Do it. Of course, as will be described later in detail, when the operating member 40 and the piston 20 are returned to their original positions, the oil 11 also returns to its original position.

In order to linearly move the piston 20 by rotating the operating member 40, the rack 22 and the pinion 41 are employed in the first embodiment of the present invention. That is, as shown in FIG. 1, the rack 22 is formed at the side of the piston 20, and the pinion 41 which is tooth-engaged with the rack 22 is formed at the central region of the operating member 40. have.

Accordingly, as described above, when the operating member 40 is rotated by applying a force for the movement, the piston 20 may linearly move in one direction by the interaction of the pinion 41 and the rack 22.

The operation member 40 is formed of an elongated rod type, and the pinion 41 is formed at the center thereof as described above. And, at both ends exposed from the device body 10, a fastener 43 for coupling the wheel 50 shown in Figure 1 is formed. A screw hole 43a is formed at the tip of the fixing tool 43.

Accordingly, as shown in FIG. 1, the wheel 50 wound around the wire 53 extending from a predetermined exercise device is coupled to the operation member 40 of the hydraulic apparatus 100 according to the first embodiment of the present invention. In order to do so, the coupling hole 51 formed in the wheel 50 and the screw hole 43a formed in the fastener 43 may be fastened by using the screw 52.

As such, when the wheel 50 is coupled to the operating member 40, the wire 50 is moved in the forward and reverse directions during the exercise through a separate exercise device, for example, as shown in FIG. 6. By rotating the wheel 50, the operation member 40 is also able to perform the movement based on a predetermined pressure while moving the piston 20.

The piston 20 is formed as a partial tubular body having a space 21 in which one end is opened, the other end is partially closed, and the oil 11 flows in the longitudinal direction therein.

Among the ends of the piston 20, the closed portion of the space portion 21 (the lower portion of the piston 20 in FIG. 1) is a pressure generated while the oil 11 filled in the space portion 21 is compressed. Therefore, a check valve (not shown) is provided to prevent the oil 11 from leaking into the other cylinder while allowing the oil 11 in the other cylinder to flow into the space 21.

As shown in FIG. 1, the funnel-shaped guide 23a having a female screw portion 23c formed at the inlet side and extending into the space portion 21 in the closed portion of the space portion 21 is shown in FIG. 1. ), A hole 23b communicating with the cylinder 12 at the center of the guide 23a, a male screw portion 23d-1 coupled to the female screw portion 23c on the outer circumferential surface, and a hole 23b communicating with the central portion. A valve cap 23d for shielding the inlet of the guide 23a with the through hole 23d-2, and provided in the space between the valve cap 23d and the pores 23b of the oil 11 through the pores 23b. Elasticity in the direction that the first ball member 23e shields the opening of the pores 23b between the first ball member 23e for selectively blocking the flow and between the first ball member 23e and the valve cap 23d. The urging member has a second elastic member 23f.

On the other hand, as described above, the lower portion of the apparatus main body 10 is provided with a pressure adjusting unit 60 for operating the operating member 40 based on the pressure added in the apparatus main body 10. 3 and 4, the pressure regulator 60 is detachably coupled to the distal end of the first passage 19a, which is a region where the first and second passages 19a and 19b meet each other. It is operated by pressure regulation, not by flow regulation. The reason why the pressure control unit 60 is detachably provided is that it can be easily replaced when it is broken or needs more precise pressure control.

The pressure regulator 60 is mounted on the distal end of the first passage 19a proximate the second passage 19b to selectively supply oil 11 to the second passage 19b through the first passage 19a. The second ball member 61 for blocking, the third elastic member 62 for elastically biasing in the opposite direction to shield the first flow path 19a, and the second ball member 61, respectively. The control member 64 pressurizes and releases the third elastic member 62 so that the opening of the first flow passage 19a may be partially opened or closed at a predetermined angle.

The adjusting member 64 is provided with an O-ring 63 for preventing leakage of the oil 11. In addition, a predetermined groove is formed in the exposed surface of the adjusting member 64. A tool such as a (-) screwdriver is inserted into the groove to be used for rotating the adjusting member 64.

Referring to FIGS. 3 and 4, a process of operating the hydraulic apparatus 100 having such a configuration is as follows.

First, in the state as shown in FIG. 3, the wheel 50 shown in FIG. 1 is rotated by a predetermined angle. Here, the rotation of the wheel 50 means that the wire 53 connected thereto is pulled to one side by operating a separate exercise device.

When the wheel 50 rotates by a predetermined angle, the operation member 40 coupled to the wheel 50 rotates by a predetermined angle in the same direction. When the operation member 40 rotates, the piston 20 moves linearly in the direction of the arrow in FIG. 3 by moving the pinion 41 and the rack 22.

When the piston 20 moves in the direction of the arrow of FIG. 3, the oil filled in the space 21 and the region of the first elastic member 30 (which is referred to as the first cylinder portion 12a) of the piston 20. 11 is directed to the first flow path 19a via the installation space of the operation member 40 through the hole 22a formed at the end of the rack 22 of the piston 20. Then, through the pressure adjusting part 60, the second flow path 19b is directed toward the rear region of the piston 20 (this is referred to as the second cylinder part 12b) (see FIG. 4).

At this time, since the second ball member 23e of the check valve is in a state of completely blocking the pores 23b formed in the center of the guide 23a by the elastic force of the second elastic member 23f, the second cylinder part ( The oil 11 in 12b) cannot be directed to the first cylinder portion 12a again.

If the third elastic member 62 is released by rotating the adjusting member 64 of the pressure adjusting unit 60 in one direction by using a tool such as a screwdriver, the second ball member 61 may be removed. The opening degree which closes the opening of one flow path 19a becomes small.

For example, when the pressure adjusting unit 60 is adjusted to move the operating member 40 by the force of 100 Kgf, when the force greater than 100 Kgf is caught by the operating member 40, the pressure adjusting unit 60 operates easily. The member 40 can be operated. However, if a force less than 100 Kgf is applied to the operating member 40, the operating member 40 is not operated due to the pressure adjusting unit 60. This in turn means that when a force less than 100 Kgf is applied to the actuating member 40, the opening degree at which the second ball member 61 closes the opening of the first passage 19a is reduced and the first passage 19a is reduced. The degree of opening / closing the opening of the valve) depends on the pressure applied, and thus the valve is referred to as the pressure regulating valve 60 in the present invention.

When the opening degree in which the second ball member 61 closes the opening of the first flow passage 19a decreases according to the pressure state, a large amount of force is required to rotate the wheel 50, and thus the amount of exercise is inevitably increased. none. If a person or a young child who has weak strength wants to use the hydraulic device 100, the second ball member 61 presses the first elastic member 62 through the adjusting member 64 so that the second ball member 61 passes through the first passage ( The opening degree which closes the opening of 19a) is expanded. Then, since the oil 11 can easily move to the second passage 19b through the first passage 19a, it is possible to exercise with little force.

After the piston 20 is moved in the direction of the arrow in FIG. 3 by moving the wheel 50 by applying a force, the compressed first elastic member 30 elastically expands when the applied force is released. 20) to the original position.

At this time, since the second ball member 23e of the check valve opens the pores 23b formed in the center of the guide 23a, the oil 11 existing in the second cylinder portion 12b is the first cylinder. It is moved to the furnace 12a. Of course, the second ball member 61 of the pressure adjusting unit 60 at this time closes the opening of the first flow passage 19a so that the oil 11 does not flow in this direction. This operation is naturally controlled by the pressure of the oil 11 in the apparatus body 10.

As such, according to the present invention, it is possible to easily adjust the rotational force applied to the operation member 40 through the pressure adjusting unit 60, the optimum exercise load according to the different physical conditions, muscle strength and exercise ability for each user By generating it is possible to maximize the effect of the exercise.

In addition, since only the rotation of the adjustment member 64 of the pressure regulator 60 has the advantage that can be adjusted relatively easily to match the optimal exercise load to fit. In addition, since the structure of the hydraulic device 100 is relatively simple and its volume and weight are low, the hydraulic device 100 can be installed in a home or a general building sufficiently to enjoy exercise.

Second embodiment

5 is a view showing a state of use of the hydraulic apparatus according to the second embodiment of the present invention. This figure shows a state in which the exercise lever 50 'is engaged without engaging the wheel 50 to the fastener 43 of the operating member 40, unlike the first embodiment described above.

As shown in the drawing, two hydraulic devices 100 are mounted to be spaced apart from each other by using a screw 70 on the predetermined mounting surface S, and the exercise lever 50 is provided on the operation member 40 of each hydraulic device 100. ')

If you exercise in this state by holding the exercise lever (50 ') with both hands in the direction of the arrow, it will be advantageous to increase the strength of the biceps and triceps muscles of the arm. Of course, if you press the exercise lever 50 'in the direction of the arrow using the legs it will be advantageous to increase the strength of the leg.

Third embodiment

6 is a schematic side view of the multipurpose exercise device to which the hydraulic device shown in FIG. 1 according to the third embodiment of the present invention is applied. This figure shows a state in which the hydraulic device 100 shown in the first and second embodiments is mounted on a separate exercise device.

In the illustrated exercise device, the first leg exercise part 81 is provided above the base member 80 having a predetermined length and width, and the user moves onto the bed 82 to one side of the first leg exercise part 81. The second leg exercise unit 83 for strengthening the lower body strength by lying down, and the upper body exercise unit 84 for strengthening the strength of the shoulders and chest sitting on the bed 82 is mounted.

The first leg movement part 81 allows the chair 81a to be slidably moved and fixed so that the chair 81a can be properly adjusted according to the user's physical condition, and has a rod 81b having a predetermined length in the wheel fastener 43. It is designed to be pressurized or released by foot.

The second leg movement portion 83 is provided with a rotatable foot portion 83a at which the user's foot or ankle is caught at the end of the bed 82, and the wire 53 is wound around the wheel fixing portion 43. 50 is provided, and the wire 53 is connected to the footrest 83a to strengthen the thigh muscles.

Upper body portion 84 is similar to the above-described leg movement portion (81,83) is installed so as to pull down the wire from the top to the bottom is to be applied to the shoulder or upper body when pulling. In addition, when the user is sitting on the bed while holding both arms to the center of the body or lying down to pull towards the upper body is applied a suitable force can effectively strengthen the muscles of the upper body.

And, one side of the bed 82 is provided with the arm movement portion 85, still, the wheel 50 of the above-described hydraulic apparatus 100 is connected to the lever 85a by a wire. Thus, the user can enjoy the arm and chest movement by pressing the lever (85a) to the upper side lying on the bed (82). This type of exercise is often referred to as a bench press. The upper side of the arm movement portion 85 may be provided with a shoulder movement portion, and the detailed description thereof will be omitted.

Referring to FIG. 6, when the wire 53 is pulled in one direction using the arm movement unit 85, the leg movement units 81 and 83, and the like, the same action as in the above-described first embodiment occurs. That is, by pulling the wire 53, the wheel 50 rotates, and in conjunction with this, the operating member 40 and the piston 20 interact with each other to give a weight necessary for the movement.

If the exercise equipment shown in Fig. 6 is required for exercise, weights such as 5 Kg, 10 Kg, etc. have been conventionally attached to the exercise equipment, and the weights have to be adjusted to the muscle strength of the user. For example, if you have a strong muscle, there are cases where the weight is set to 200Kg or more.

As such, the body of the exercise equipment is heavy, but if the weight required to prepare more than a few hundred kilos, in this state can be forced to use at home. However, according to the present invention, it is concluded that there is no difficulty in using at home because only a simple and low weight hydraulic device 100 needs to be prepared instead of hundreds of kilograms of weight.

Fourth embodiment

7 is a cross-sectional view of a hydraulic apparatus according to a fourth embodiment of the present invention, and FIG. 8 is an enlarged cross-sectional view taken along the line A-A of FIG. As shown in these figures, the hydraulic apparatus 200 according to the fourth embodiment of the present invention is implemented as described above in that the piston 220 and the first elastic member 30 are provided in the apparatus body 10. The same as the hydraulic device 100 of the examples, but the structure of the piston 20 is different from the above-described embodiments.

The piston 220 disclosed in the fourth embodiment of the present invention has a shape in which the inside is not empty and has a substantially "I" shape in which its side is recessed toward the radially inner side, and the rack is cut inward. 222 is formed. Of course, the rack 222 is geared with the pinion 41.

Accordingly, by rotating the wheel (not shown) to rotate the operation member 40 in one direction, the piston 220 is moved toward the right direction of FIG. Then, the oil existing in the first cylinder portion 12a in which the first elastic member 30 is positioned is transferred to the second cylinder portion 12b via the first flow passage 19a and the second flow passage 19b. Impart pressure. At this time, as described above, the first flow passage 12a is capable of adjusting the pressure applied due to the pressure regulating valve 60 by the pressure type control rather than the flow rate control. The illustrated pressure control valve 60 is replaced by the above description.

When the force applied to the operation member 40 is released, the compressed first elastic member 30 expands to its original state and moves the piston 220 in the left direction of FIG. 7. Then, the oil in the second cylinder portion 12b is transferred to the first cylinder portion 12a through the check valve 23. Of course, at this time, the oil is prevented from moving to the first and second flow paths 19a and 19b due to the pressure regulating valve 60.

According to the hydraulic apparatus 200 having such a configuration, the weight and the volume of the piston 220 can be reduced, and thus it can provide an additional effect of reducing the volume of the hydraulic apparatus 200 as a whole.

Meanwhile, in FIG. 7, caps 13 are coupled to both ends of the apparatus body 10 by fastening portions 14, respectively. The slider 13b is mounted in the apparatus main body 10 adjacent to the cap 13 on the right side, and the slider 13b and the cap 13 are integrally coupled to the screw shaft 13c. A knob 13e is formed at the exposed end of the screw shaft 13c.

Accordingly, when the knob 13e is grabbed and rotated, the screw shaft 13c rotates in one direction, and in response thereto, the slider 13b moves toward the piston 220. Then, the first elastic member 30 is in a compressed state to some extent than the original state.

As such, when the first elastic member 30 is compressed using the slider 13b to freeze, the movement of the wheel as described above may be performed, and more power may be required than the initial state. As a result, the compression state (elastic force) applied to the first elastic member 30 can be adjusted by the configuration of the knob 13e, the slider 13b, and the screw shaft 13c.

Although the compression state (elastic force) applied to the first elastic member 30 can be adjusted by the configuration of the knob 13e, the slider 13b, and the screw shaft 13c, it is shown in FIG. 7 only. The same may also be applied to all embodiments to be described later, including these.

Fifth Embodiment

9 is a sectional view of a hydraulic apparatus according to a fifth embodiment of the present invention. The hydraulic apparatus 300 shown in this figure also differs only in part from the hydraulic apparatuses 100 and 200 of the above-described embodiments, and the principle is the same.

That is, unlike the hydraulic apparatuses 100 and 200 of the above-described embodiments, the apparatus main bodies 310a and 310b of the hydraulic apparatus 300 according to the fifth embodiment are composed of two parts spaced apart from each other. Of course, these two parts are interconnected centrally. The first elastic member 30 described above is provided in the apparatus body 310a on the right side. However, no oil is provided in the apparatus main body 310a, and one side of the apparatus main body 310a is provided with a pressing plate 315 for pressing the first elastic member 30 by the rack 320 to be described later.

Unlike the above-described embodiments, the piston 320 disclosed in FIG. 9 has an elongated rod shape, the inside of which is not empty, and a rack 322 is formed in one outer region, and a screw 340 is disposed on an opposite side of the rack 322. The rack support part 345 which is supported by and moves together with the rack 332 is formed. The rack support portion 345 is provided with a check valve 23. The rack 332 is provided in an exposed type disposed between the device bodies 310a and 310b. Of course, the rack 332 is in gear mesh with the pinion 41 of the operating member 40.

In the apparatus body 310b on the left side, first and second cylinder portions 12a and 12b are provided in the same manner as in the above-described embodiments. In addition, the pressure adjusting unit 60 is positioned above the piston 20. At this time, by forming a taper (64a) at the tip of the control member 64 of the pressure adjusting unit 60 to adjust the pressure to reduce the number of parts than the above-described embodiment, the same performance can be maintained while lowering the cost To make it possible.

Accordingly, when the wheel (not shown) is rotated to rotate the operation member 40 in one direction, the piston 320 moves to the right direction of FIG. 9 to push the pressure plate 315 to compress the first elastic member 30.

At the same time, the oil existing in the first cylinder portion 12a is transferred to the second cylinder portion 12b via the first flow passage 19a and the second flow passage 19b, together with the first elastic member 30. Apply exercise pressure.

At this time, the first passage 12a can adjust the pressure applied due to the pressure control valve 60 by the pressure control rather than the flow rate control, which is easier to control than the above-described embodiments.

When the force applied to the operating member 40 is released, the compressed first elastic member 30 expands to its original state and moves the piston 320 to the left side of FIG. 9. Then, the oil in the second cylinder portion 12b is transferred to the first cylinder portion 12a through the check valve 23. Of course, in this case, the oil is first and the first due to the pressure regulating valve 60. Movement to two euros 19a and 19b is impeded.

According to the hydraulic apparatus 300 having such a configuration, since the weight and volume of the apparatus main bodies 310a and 310b and the piston 320 can be reduced, the additional effect of reducing the volume of the hydraulic apparatus 300 as a whole can be reduced. Can be provided.

Sixth embodiment

10 is a perspective view of the pressure regulator according to a sixth embodiment of the present invention, and FIG. 11 is an exploded perspective view of the pressure regulator shown in FIG. 10. The pressure regulator 160 shown in these figures is the same as the above-described pressure regulator 50, but the structure is different.

That is, the aforementioned pressure adjusting unit 50 has a (-) type groove formed at the tip of the adjusting member 64, and in order to rotate the adjusting member 64 for pressure control, a separate driver such as a driver I needed a tool. However, it is sometimes cumbersome to prepare a driver and control the pressure during exercise.

Thus, in the sixth embodiment of the present invention, by using the knob 167, which is in the form of a conventional handle, the pressure adjusting unit 160 is configured to eliminate all such inconvenience and inconvenience. .

The pressure regulating unit 160 according to the sixth embodiment of the present invention includes the first passage 19a close to the second passage 19b when referring to FIGS. 10 and 11 including FIGS. 3 and 4 described above. And a third ball member 161 and a third ball member 161 mounted on the distal end of the cuff to selectively block the supply of the oil 11 to the second flow passage 19b through the first flow passage 19a. The fourth elastic member 162 elastically biased in the opposite direction to shield the flow path 19a, the adjusting body 163 having the through hole 163a formed on the plate surface, and the through hole 163a of the adjusting body 163. A cylindrical first cylinder 166 having an exposed portion 164 exposed to the outside and a movable portion 165 having a cutting slot 165a formed on the side thereof, and an exposed portion 164 of the first cylindrical body 166. ) Is coupled to the knob 167 and the first cylinder 166, a spiral hole 168b is formed at the side and a pair of first extension protrusions 168a extending radially outward at one end thereof. In the second column 168 and the second column 168 A pair of second extension protrusions 169a inserted and extending radially outwardly are integrally inserted into the spiral hole 168b and the cutting slot 165a to rotate the fourth elastic member 162 by the rotation of the knob 167. And a pressurizing unit 169 for pressurizing and releasing the pressurization.

Extension slots 165b and 165c which are bent in opposite directions are formed at both ends of the cutting slot 165a of the first pillar 166. After the knob 167 is fitted to the exposed portion 164, the exposed portion 164 has a non-circular cross section in order to prevent idleness. An end of the knob 167 is equipped with an O-ring 170 to prevent the oil 11 from leaking.

And, on the plate surface of the adjusting body 163, an adjustment scale 163b for adjusting the rotation angle of the knob 167 is formed. The adjustment scale 163b may correspond to, for example, 5Kg, 10Kg of the above-described weight, and when the knob 167 is rotated to move one division, the pressure corresponding to the weight of 10Kg may be adjusted. have.

Thus, if the person with relatively weak muscle power is to weakly adjust the pressure applied to the hydraulic device using the pressure control unit 160, grab the knob 167 and turn in one direction to match the corresponding adjustment scale (163b). Then, the first pillar 166 is rotated by the rotation of the knob 167, the second extension protrusion (169a) formed in the pressing unit 169 is spiraled by the rotation of the first cylinder 166. While moving along the ball 168b, it moves toward the fourth elastic member 162 side.

When the protruding end 169b of the pressing unit 169 presses the fourth elastic member 162, the fourth elastic member 162 is compressed and the third ball member 161 of the first flow path 19a is pressed. The opening degree of closing the opening is widened. Then, since the oil 11 can easily move to the second passage 19b through the first passage 19a, it is possible to exercise with little force.

On the contrary, if a person having a relatively strong strength wants to strongly control the pressure applied to the hydraulic device using the pressure adjusting unit 161, the knob 167 is rotated in the opposite direction to apply to the fourth elastic member 162. Loosen the power. Then, the opening degree in which the third ball member 161 closes the opening of the first passage 19a is narrowed, so that the third ball member 161 can exercise with a strong force.

As such, if the pressure control unit 161 according to the sixth embodiment of the present invention is employed and the hydraulic device is employed in the exercise device as shown in FIG. 6, the hydraulic device is rotated while the knob 167 is rotated by hand during the exercise. You can adjust the pressure applied. Therefore, there is an additional advantage that both weak and strong people can use the hand easily.

Although the embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited thereto.

In the above-described embodiment, the rack member and the pinion type have been described in the operating member and the piston, but a plurality of bevel gears may be combined to convert the rotational motion of the operating member into the linear motion of the piston.

In the above-described embodiment, the apparatus body is described as a metal material, but may be replaced with engineering plastics, synthetic resins, or the like.

The pressure regulating valve 60 shown in the above-described fifth embodiment may be equally employed in all the above-described embodiments in addition to the fifth embodiment.

As described above, according to the present invention, there is provided a hydraulic apparatus of a multipurpose exercise device that maximizes the effect of exercise by generating an optimal exercise load according to different physical conditions, muscle strength, and exercise ability for each user.

In addition, according to the present invention, it is relatively easy to adjust the work to match the optimal exercise load, and relatively simple in structure, and its volume or weight is low, so that enough to install in the home or general building to enjoy the exercise Hydraulics of a multipurpose exercise machine are provided.
