The present invention relates to a fitness equipment, and more particularly, to a multi-purpose fitness equipment for weight training, such as a body weight exercise that does not generate any noise and vibration at all during exercise without weight attached to the existing weight adjustment weight.

Conventional fitness equipment for strength training is a fitness equipment that increases the size and muscle strength of muscle fibers by stimulating and expanding muscles by gravity weight or fingering means, each part of the body that did not receive blood supply smoothly due to increased blood flow The vitality of blood supply to the field, the expansion of new cells and muscle tissues, and the improvement of endocrine circulation effectively improve other functions of the body, which can increase disease resistance and reduce senescence. Of course, by strengthening the metabolism in the body has the effect of increasing the efficiency of nerves, respiration, circulation, reproduction, digestion, excretion.

In general, as a fitness equipment for strength training, weight training equipment is generally used, and in addition to simple load movements such as dumbbells, dumbbells and bench presses, the butterfly, leg curls, leg extensions, and high weights are used. There are load-bearing strength exercise mechanisms such as pulleys and long pull machines.

In this variable weight training apparatus, the weight of the weight is set according to the user who uses the apparatus, and the weight is inconvenient to transport and store. It was not suitable for indoor use because it would generate loud noise.

In addition, the Republic of Korea Utility Model Registration No. 418049, as shown in Figures 1 and 2, by adjusting the weight of the weight mechanism by using the intensity of the current supplied to the electromagnet can exercise at a suitable weight for the user There is one configured. That is, as shown in Figures 1 and 2, the frame 112 is formed so that the space 111 therein; A weight housing (110) provided in front of the frame (112) so that a user can sit or lie down and have a pedestal (114) made of a chair type capable of adjusting an angle; A guide roller 122 rotatably positioned on an upper portion of the space 111 of the frame 120; The outer circumference is guided to the guide roller 122, the weight 130 of the appropriate weight is fixed at one end is located in the space 111 of the frame 120, the other end of the handle 140 for the user to grip Up / down device 120 is composed of a movable wire 124 is fixed; And a weight adjusting device 150 provided inside the space 111 of the frame 112 and configured to detach the weight 130 from a magnetic field generated by the user from the outside and input the current from the outside. Consists of, the weight adjusting device 150 is a current regulator 152 installed on the bottom of the space portion 111 of the frame 112; A current inputter 154 connected to the current regulator 152 so that a user inputs an appropriate current to the current regulator 152 from the outside; And an electromagnet 156 connected to the current regulator 152 and configured to generate a magnetic field by the strength of the current input to the current inputter 154 so that the weight 130 is pulled.

When the weight mechanism using the electromagnet according to the prior art configured as described above pulls the weight 130 attached to the electromagnet 156 through which the current flows, the weight 130 is pulled upward by the pulling force of the user. It is separated from the electromagnet 156. At this time, the electromagnet 156 generates a magnetic field corresponding to the strength of 40A, when the user pulls the same or less than the magnetic field, the weight 130 is not pulled upward, the user is suspended on the handle It will not keep weight training (upper body strength).

However, in the prior art as described above, when the user pulls the handle of the weight mechanism to perform the weight movement, the weight 130 attached to the electromagnet is released upward and the force pulling the weight 130 by the magnetic field is obtained. In this case, the user pulls the handle and the weight 130 is separated by a certain distance (L), and the strength of the magnetic field is sharply attenuated, even though a very short distance is not affected by the magnetic field at all. There was a problem of not being present.

In order to solve the above-mentioned problems of the prior art, the inventors of the present invention have disclosed the Korean Patent Application No. 2006-123765 "Load control apparatus for a weight exercise mechanism using an electromagnet", but the prior art and the inventor of FIG. Since the preliminary application of the electromagnet also uses the principle of electromagnetism, it is possible to operate only when the power is supplied and the critical point of the electromagnet cannot act indefinitely. Although effective strength exercise is possible, there is a problem that the exercise effect is reduced because almost no exercise in the state almost open arms. In particular, in the case of the prior art of FIG. 1, there is a problem because the magnetic field range of the electromagnet is limited, and in the case of the present application of the present inventors, this disadvantage is somewhat compensated by the on / off switch, but also unidirectional strength exercise. There is a problem that is limited to.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, but the technical idea of the present invention is not limited thereto and can be variously modified and modified by those skilled in the art.

3, 4 and 5 are an elevation view of the fitness equipment according to the first embodiment of the present invention, and a front detail and a side detail view of the driving unit, respectively, and FIGS. 6, 7 and 8 are the present invention, respectively. An elevational view, a front detail, and a side detail view of a fitness device according to a second embodiment of the present invention.

In the fitness device according to the first embodiment of the present invention, as shown in FIG. 3, the driving unit (see FIG. 4), which is the core of the fitness device of the present invention, is located at the lower end of the appliance frame 1 on the elevation, and the frame 1 A guide roller 9 is installed at an upper end thereof, and the wire rope 11 drawn out of the driving unit is connected to a handle 12 that can be held by a user through the guide roller 9. And an operation panel 10 for controlling the driving (loading) of the fitness device of the present invention is provided on the side or other suitable space of the frame (1).

3 and 4, the driving unit of the fitness device of the present invention will be described in detail.

One end of the lead arm 2 of the present invention is rotatably hinged to the hinge 13 located at one side of the support frame 3 of the base of the mechanism frame 1 of the present invention. At the other end, a roller 39 on which the wire rope 11 is caught is provided.

In addition, a gas spring 4 is disposed between the other end of the lead arm and the guide block 7 positioned at an arbitrary position of the support frame, thereby moving the wire rope 11 in the direction of the arrow in FIG. 3. As it is pulled in, the gas spring is pivoted while being compressed in the "I" direction.

Therefore, as the user pulls the wire rope 11 in the "ga" direction, the gas spring 4 compresses in the "b" direction to exercise the muscle strength to the user. When the 11 is slowly released, the lead arm 2 is returned to its original initial position by the compressed force of the gas spring 4.

One end of the wire rope 11 is connected to the support frame 3, and the wire rope 11 is wound on a roller (39 in FIG. 5) embedded at the other end of the lead arm 2, and again at a proper position of the support frame (preferably It is preferable that the structure is wound on the roller 19 installed on the right side in the drawing and the other end is finally connected to the handle 12, but the gas spring 4 installed between the lead arm 2 and the support frame 3 It does not matter what combination method produces the compressive force. In addition, in the strength-strengthening exercise in which the user pulls the wire rope upward, only the roller 19 mounted on the support frame 3 is sufficient, but the user pulls the wire rope 11 downward. At the time of strength strengthening movement of the wire rope, the wire rope can be pulled downward through the roller 9 suspended from the ceiling of the mechanism frame 1 as described above, and the direction of the wire rope 11 is changed in some cases. It is preferable that the roller 29 of the intermediate position of a line separate is provided in the intermediate position of the instrument frame 1.

The gas spring is not necessarily limited to this, and may be replaced by a compact hydraulic cylinder or any other hydraulic compressor.

On the other hand, as described above, in the form of fixing the guide block 7 for supporting one end of the gas spring 4 at any position of the support frame 3, only a fixed compression force can be generated, the present invention In a preferred embodiment of the screw shaft 5 is fixed to the support frame 3 via the left and right screw shaft support 6, the guide block 7 is guided by the screw shaft 5, yes For example, when the guide block 7 is moved in the direction of the "multi" arrow in FIG. 3 (to the right in the drawing), the direction of the pressing force of the wire rope 11 and the direction of the pressing force of the gas spring 4 generally coincide. As a result, the user can perform the strength strengthening movement with a relatively smaller force, and conversely, as the guide block 7 is moved to the left in the drawing direction, a larger force is required, resulting in a load increase. It is possible to change the strength exercise device.

Reference numeral 8 denotes a motor 8 for rotating the above screw shaft 5 to eventually change the position of the guide block 7, which is electrically controlled by the operation panel 10 to control forward and reverse rotation. That is, for example, an encoder (not shown) for detecting the amount of rotation of the screw shaft 5 is installed, the current amount of rotation of the screw shaft 5 is detected from the encoder and the desired rotation from the user. The screw shaft 5 such that the operation panel 8 generates a pressing force corresponding to various virtual weights, including an operation panel 10 that receives a value and controls the rotation of the motor 8. The motor 8 is controlled to select the position of the guide block 7 by rotating. Reference numeral 14 is an electrical connector.

However, the screw shaft is not necessarily to be operated only by the motor, it is also possible to rotate by manually rotating the screw shaft (5) with a separate manual handle, furthermore, the guide block (7) is also necessarily It does not have to be repositioned only by the screw shaft 5, but the shaft 5 is a rod-shaped shaft with a plurality of pin insertion grooves in a proper position and a pin for fixing the guide block 7 (not shown) is used. It is also possible to move by the separate position conversion apparatus, such as changing the position of the guide block 7.

In addition, Figure 5 is a cross-sectional view of the right side AA line of the drive unit of the present invention, as shown in Figures 4 and 5, in order to eliminate the left and right deflection, or to simultaneously perform both arms movement, the gas spring 4 and It is preferable to install two rollers 39 on both sides to achieve symmetry, but the number of gas springs and the number of rollers 39 may be variably implemented according to embodiments.

Now, when the operation of the fitness device of the first embodiment of the present invention described above, the position of the guide block 7 is set by connecting the electrical connector 14, turning on the power, and setting a desired load on the operation panel 10. . At this time, for example, the position of the guide block 7 allows to set the compression force corresponding to the weight weight to 10kg, 15kg, 20kg, 30kg and the like. Then, the screw shaft 5 rotates according to the rotation direction of the motor 8 so that the gas spring 4 is moved along the guide block 7 by a load set back and forth.

At this time, when the athlete pulls the handle 12, the wire rope 11 pulls the lead arm 2 along the plurality of guide rollers 39, 19, 29, and 9 to press the gas spring 4. The gas spring 4 is provided with a repulsive force over the entire range of the stroke as much as the set load, and the load is constantly maintained even when the athlete pulls or releases the handle 12, thereby using a weight strengthening exercise mechanism. Will act the same as.

6 to 8, the fitness device of the second embodiment of the present invention will be described. The mechanism of this second embodiment is substantially the same as that of the first embodiment, but differs only in that it further has a guide rail 15 and a track roller 16. Therefore, the same member is used for a member that performs the same function as the first embodiment. Number it and omit its detailed description.

In order to be able to use the load-variable strength exercise mechanism in the above-described first embodiment, the lower support point of the gas spring 4 must be shifted in position so that the gas spring 4 is mounted on the guide block 7. It should be capable of turning to some extent about the pivot axis 7a. However, since the pivot shaft 7a must be pivoted under the compressive load of the gas spring 4, it may be somewhat unreasonable as time goes by and lack of lubrication.

In the case of the second embodiment, the guide block 7 only holds the direction in which the compression force of the gas spring 4 acts (so in the second embodiment the gas spring 4 is fixed to the guide block 7). The compression force of the gas spring 4 acts on the track roller 16 which rolls along the guide rail 15. In addition, it is preferable that the guide rail 15 has a constant curvature of a virtual circumference having a constant radius with the connection point between the upper end of the lead arm 2 and the upper end of the gas spring 4 as the center of the virtual circle. .

Therefore, when the gas spring 4 is compressed, a compressive force acts on the rotation axis of the track roller 16, and the track roller 16 performs rolling motion on the inner circumferential surface of the guide rail 15 having a constant curvature. Compression can be more smoothly and durability can be increased.

9 and 10 are elevation and side cross-sectional views, respectively, in the state where the fitness equipment of the present invention is embedded in a wall. In other words, since the fitness device according to the present invention does not require weights or electromagnets, it is possible to manufacture compactly above all, and to minimize noise, so that the fitness device is installed in a built-in manner in a wall of an apartment house such as an apartment or a multi-generational alliance. It is possible.

9 and 10, a rectangular frame 31 into which the apparatus frame 1 of the present invention can be embedded is formed in the wall 30 of the house, and the rear surface of the lightweight partition 35 is formed. After doing so, the inner box 20 is made of the space to install a seat 21 and the back 22 which the user can sit while exercising. Preferably, these seats are supported by the seat support 23, but when the fitness equipment is not used, the seat 21 and the seat support 23 using the backrest control rail 24 to the inner box 20 To fold in.

Therefore, when not using the fitness device of the present invention by folding the seat and the backrest to minimize the space, and only to use them to expand the bar to use the fitness device of the present invention, which is a compact fitness device of the present invention This is possible because noise and vibration are minimized.

Reference numerals 32, 33, and 34 are open and close doors, a bottom body, and a ceiling, respectively.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawings.

As described above, according to the fitness device of the present invention, the gas spring (4) generates a repulsive force over the entire range of the stroke distance by the set load desired by the exerciser, the athlete pulls or releases the handle 12 Even when the load is constantly maintained, the same effect as the muscle strengthening exercise mechanism using the weight.

In addition, according to the fitness device of the second embodiment of the present invention, the compressive force of the gas spring 4 acts on the rotation axis of the track roller 16, the track roller 16 is a guide rail 15 having a constant curvature ) Because of the rolling motion on the inner circumferential surface, a more smooth compression movement is possible and durability can be increased.
