The present invention relates to an upper body exercising apparatus, and more particularly, to the upper body exercising apparatus that can quickly return to the operating state after removing the external force after operating the upper body exercising apparatus.

In order to maintain a healthy body, regular exercise for each part of the body is necessary, but busy modern people lack the time and mental room to enjoy exercise. In recent years, various exercise devices have been developed that can easily exercise each part of the body even in a narrow space in the room.

Domestic Utility Model Registration No. 219913, Domestic Utility Model Registration No. 261703, Domestic Utility Model Registration No. 265366, and Korean Patent Registration No. 10-0500510, as described above, can be exercised in a small space to exercise the body. As a mechanism, a schematic description is as follows.

First, the "training apparatus" of the domestic utility model registration No. 219913, the elastic member is inserted into the protective cover formed longer than the maximum tensile length of the elastic member so that both ends of the protective cover is connected to both connecting bands together with both ends of the elastic member. do. And one side of the connection band is coupled to a fixed member that can be fixed to the fixture arbitrarily, the other side of the connection band is a form of the auxiliary member that is detachable for use by the exerciser selectively according to the type of movement, various types such as judo, land, swimming It is aimed at becoming an effective strength booster in the sports field.

However, such a conventional exercise device uses only the inherent elastic force of the elastic member, so that the same exercise load is applied to all people, and thus is suitable for a specific person having an exercise ability suitable for the set exercise load, but others are described above. When you exercise with one exercise equipment, adverse effects such as weak exercise effects or excessive body pressure occur.

Utility slide registration No. 261703 disclosed in the domestic "slide exercise mechanism", the support plate is installed in the upper rear of the I-shaped floor frame, the inclination adjustment plate is installed in the upper front of the I-shaped floor frame freely within a certain range, A slide plate having a handle on the inclination control plate is installed to reciprocate in the front and rear direction, and thus it is possible to train each part of the body such as the arm and the abdomen while reciprocating in the front and rear direction.

However, since such exercise equipment cannot adjust the force required to reciprocate the slide plate in the process of reciprocating the slide plate, the same exercise device also causes the same problem as described above.

Korean Utility Model Registration No. 265366, "Strength strengthening exercise device", the support plate, the outer pipe is installed vertically on the support plate, the inner pipe which is inserted from the upper portion of the outer pipe and slides between the outer pipe and the inner pipe Compression spring is installed to enable the elastic slide movement of the inner pipe relative to the outer pipe, a handle coupled to the upper portion of the inner pipe, and a plurality of rubber bands attached to the side of the outer pipe and installed between the handle and the support plate Consisting of a pair of sports balls, by fixing a pair of sports equipment made to be elevated by the elastic force of the compression spring at a certain distance on the support plate to enable the user to exercise in standing or lying down to strengthen the muscles.

By the way, such a conventional exercise device also because the elastic force of the compression spring is fixed fixedly, the same exercise load is operated for everyone, and eventually does not provide the optimal exercise conditions for various classes of people.

Korean Patent No. 0500510 "Hydraulic device of the multi-purpose exercise equipment" is to solve the problems of the three conventional exercise equipment described above, it is possible to appropriately adjust the exercise load to suit users with different physical conditions, muscle strength, exercise ability Device.

1 and 2 are cross-sectional views showing the operating state of the above-described Patent No. 0500510, which is a prior art, a predetermined cylinder (3) filled with the oil (2) is formed inside the oil is partially moved An apparatus body 1 having a plurality of flow paths 4 and 5 and a central region disposed in the apparatus body 1 and at least one of both ends thereof are exposed from the apparatus body 1 so as to be able to rotate at a predetermined angle forward and backward. It is provided in the cylinder 3 so as to be partially engaged with the member 6 and the operation member 6, and is movable along the longitudinal direction of the apparatus main body 1, and is linear in the cylinder 3 during the rotational movement of the operation member 6. It is mounted on any one side of the apparatus main body 1 so as to partially open and close any one of the moving piston (7) and the plurality of flow passages (4) (5) to adjust the rotational pressure applied to the operating member (6) The pressure adjusting section 8, the piston 7 and the cylinder of the apparatus body 1 (3) is provided between the first elastic member (9) elastically deformed in the opposite direction to move the piston (7) when the operating member (6) is rotated in one direction to move the piston (7) linearly in one direction. .

Such a conventional patent discloses that when a wire (not shown) is pulled in an initial state as shown in FIG. 1, a wheel (not shown) in which the wire is wound and an operating member 6 installed coaxially with the wheel are rotated to form a piston ( 7) is advanced and the first elastic member 9 is compressed. At this time, the oil 2 of the first cylinder portion 3a moves toward the rear side of the second cylinder portion 3b generated by the piston 7 moving forward. It is conveyed and becomes the state as shown in FIG. When the external force is removed from the drawn wire, the piston 7 is retracted by the restoring force of the first elastic member 9, and the oil 2 on the second cylinder part 3b side is transferred back to the first cylinder part 3a. The device operated as shown in FIG. 2 is restored to its original state as shown in FIG. 1.

By the way, such a conventional patent, it takes a relatively long time until the device in the operation state once returned to the original operation to perform the next operation, accordingly, the user operates the device of the conventional patent once and then performs the subsequent operation In order to return the device for a relatively long period of time, which in turn reduces exercise efficiency.

That is, when the external force is removed from the pulled wire as shown in FIG. 2, the compressed first elastic member 9 is restored and the piston 7 is pushed. At this time, the oil 2 in the second cylinder part 3b is very narrow. The return time of the piston 7 and the first elastic member 9 is delayed because it must be transferred into the first cylinder portion 3a through the second flow passage 5, the first flow passage 4 and the hole 7a.

Particularly, since the oil 2 is filled in the entire inside of the apparatus body 1 of the conventional patent, the oil 2 remains in the above-described path even when the elastic restoring force of the first elastic member 9 is applied in this state. If you have to wait for a tedious time until it returns after operating the hydraulic system of the conventional patent once, the movement effect is halved, and the invention is not very practical for the modern man who struggles with a hillside. to be.

On the other hand, in order to reduce the return time of the first elastic member 9 and the piston 7 of the conventional patent, a spring having a very large elastic restoring force may be used, but in this case, the return speed of the piston 7 may be slightly improved. However, as the load on exercise equipment rises relatively large, people with poor strength, including women, are virtually impossible to operate such exercise equipment.

Therefore, the method of improving the restoration speed of the above-described registered patent by improving the elastic restoring force of the first elastic member 9 is not very helpful in solving the problem of the above-described conventional patent, and finally, the conventional patent is There is a fatal problem to be put into practical use and popularization.

1, 5, 6, and 9 as shown in Figs. 1, 5, 6, and 9 on the corresponding outer side of the first side plate 13 and the second side plate 14 of the upper body exercise apparatus of the present invention Plate 90 is installed. Here, the foot plate 90 is installed on the two side plates by the following combined structures, the support bar support 92 is coupled to the outside of the first side plate 13 and the second side plate 14, respectively, this support One end of the support bar 91 is coupled to the bar support, and the foot support 93 is coupled to the support bar 91 so that the foot plate 90 is coupled thereto.

Here, the support bar 91 is preferably provided in the form of a pipe having a hollow shape so that the weight thereof is reduced, the support bar cover 94 is coupled to the end of the support bar 91, the foot plate 90 The non-slip pad 95 is attached.

The operation of the upper body exercising apparatus of the present invention in this configuration is as follows.

After the user transfers the upper body exercising apparatus of the present invention to an appropriate space, a separate chair is placed at the rear of the upper body exercising apparatus of the present invention and the two feet are placed on the foot plate 90 while sitting on the chair, Hold both sides of the handle.

Since the support bar 91 is formed in the form of a hollow pipe, the weight of the upper body exercise device of the present invention is reduced, and is easy to transport, and the anti-slip pad 95 is attached to the foot plate 90. Even if the leg is applied during exercise, the supporting sole does not easily slide on the foot plate 90.

In such a state, when the two arms are pulled back or the upper body is pushed back together with the two arms, the cable 16 is pulled out and pulled out of the long groove 15a of the main cover 15. By this operation, the upper body exercising apparatus of the present invention The internal parts of them are operated as follows.

That is, when the cable 16 is pulled, the cable wheel 41 of the cable winding means 40 is rotated, and the shaft 30 coupled thereto is rotated in the direction of the arrow A as shown in FIG. 17, so that the cylinder rod 51 and the piston are rotated. (20) in the direction of the arrow (B), by which the spring 21 is compressed by them, the oil inside the cylinder 18 passes through the first flow path (60b) of the cylinder nut (60) its entrance space (60a) ) Flows inside.

Since the bearing 29 is installed on the cylinder rod 51 in contact with each other to support the cylinder rod 51 and guide the transfer thereof, even if the upper body movement device of the present invention vibrates severely during the movement, the free end of the cylinder rod 51 The shock is prevented from being shaken, thereby keeping the engagement state of the pinion 52 and the rack gear 51a securely.

On the other hand, when oil flows into the inlet space 60a of the cylinder nut 60 from the inside of the cylinder 18, the first and second check valves 73 and 85 are closed, so the cylinder nut 60 is closed. The oil introduced into the oil tank 70 is not directly introduced into the oil tank 70 through the second flow path 60c and the first check valve 73, and is moved outward through the air passage 60e and the second check valve 85. It may not be discharged and flows into the auxiliary tank 81 through the third flow path 60d in the direction of the arrow C. When the piston 20 continues to be transported and the oil inside the cylinder 18 is pushed out toward the entrance space 60a of the cylinder nut 60, some of the oil flowing into the auxiliary tank 81 is transferred through the hose 84. Inflowed into the oil tank 70 and stored.

In order to increase the pulling force of the handle, the flow shaft 87 is lowered by rotating the knob 89 of the flow adjusting unit 86 so that the flow rate of the stopper 87a of the flow shaft 87 and the auxiliary tank 81 can be reduced. The gap between the adjustment holes 82c may be narrowed. On the contrary, to reduce the pulling force of the handle 17, the knob 89 may be rotated in the opposite direction to raise the flow shaft 87 so that the stopper portion of the flow shaft 87 may be increased. What is necessary is just to widen the clearance gap between 87a) and the flow regulating hole 82c of the auxiliary tank 81.

Therefore, it is possible to easily adjust the force acting on the cable 16 by a simple operation of rotating the knob 89, according to the various people can be easily adjusted and used according to their exercise conditions.

When the upper body exercise device of the present invention grabs the handle 17 and pulls both arms back or the upper body with both arms back, one operation is finished, and the user stretches back or pushes back both arms in the original state. By raising the upper body in the state to remove the external force acting on the handle 17, in this way the upper body exercise apparatus of the present invention can be pulled back to the original again.

Here, the upper body movement device of the present invention, when the user removes the external force from the pulled handle 17, is quickly returned to the user to quickly perform the next operation, as shown in Figure 18 by the restoring force of the spring 21 piston 20, the cylinder rod 51 is rotated in the direction of the arrow D to rotate the pinion 52 and the shaft 30 in the direction of the arrow E. At this time, the first check valve 73 and the second check The valve 85 remains open.

Therefore, the oil in the oil tank 70 flows into the entrance space 60a of the cylinder nut 60 through the first check valve 73 and the second oil halo bla 60c, and at the same time, the auxiliary tank 81 The oil inside also flows in and out of the space 60a of the cylinder nut 60 through the flow rate adjusting hole 82c and the third flow path 60d.

Therefore, when the spring 21 is restored, not only the oil in the oil tank 70 is introduced into the cylinder nut 60, but the oil in the auxiliary tank 81 is also supplied into the cylinder nut 60. 60 is quickly introduced into the inside, the introduced oil is introduced into the cylinder 18 through the first flow path (60b).

In addition, when the oil in the oil tank 70 and the oil in the auxiliary tank 81 flow into the cylinder nut 60, the outside air flows together through the second check valve 85 into the cylinder nut 60. Bars and oils are more viscous than water, so when the oil is filled in the cylinder nut 60 and the cylinder 18 only, the oil is not rapidly transferred due to the high voltage. Therefore, when the oil in the oil tank 70 and the oil in the auxiliary tank 81 flow into the cylinder nut 60, the outside air is further introduced by the second check valve 85, so that only the oil is filled and transported. The feed rate of oil becomes faster and smoother.

And since the inner diameter of the first passage 60b is the same as the inner diameter of the cylinder 18, the oil quickly flowing into the cylinder nut 60 is quickly introduced into the cylinder 18 through the relatively wide first passage 60b. Finally, the return acceleration means 80 accelerates the restoration of the spring 21 and the linear movement of the piston 20, the cylinder rod 51, the pinion 52, the shaft 30, and the cable wheel 41. The upper body exercising apparatus of the present invention is quickly returned.

Fig. 19 is a schematic partial sectional view showing another embodiment of the cable winding means according to the present invention, which is formed around the cable wheel 41 'with a flange 41d' and a cable groove 41c 'formed therein. 41 '), the wheel cover 42' is installed to surround the cable hole 41 ', and the cable hole 41e connected to the cable groove 41c' is formed at one side of the cable wheel 41 '.

The cable winding means 40 is formed in the cable wheel 41 'rather than the cable hole 41e in the wheel cover 42', so that the cable hole 16 in which the cable 16 'is formed in the cable wheel 41' ( The functions and effects are the same as described above, except that they are connected to the outside through 41e).

As described above, in the present invention, when the external force is removed from the pulled cable, the spring is restored and the first check valve is opened to supply oil in the oil tank to the cylinder nut, and the remaining oil in the auxiliary tank also flows into the third channel of the cylinder nut. Since a large amount of oil is quickly introduced into the cylinder nut and the cylinder, the second check valve opens when the oil in the oil tank and the oil in the auxiliary tank flow into the cylinder nut. Since the nut is introduced into the nut, the upper body movement device of the present invention operated by the oil flowing into the cylinder more quickly and smoothly is quickly returned.
