Installed on the upper rod (7) to exercise while pulling down, the seat rod (9) installed on the front of the seat (S) with a hinge (8) installed to exercise such as leg curl, and One chest press (6) and top rod (7) It is connected by a plurality of wires (W) and roller (R) to apply a load to the rod (9), respectively, and consists of load applying means configured to change the load by controlling the current and applying the load by magnetic force. .

In addition, as shown in Figure 3, the guide rod 10 is installed upright at a predetermined height on the foot portion of the bottom support (2) as described above, and the rubber (RB) for noise prevention and cushioning is attached to the upper end, and As a guide rod 10 is inserted into the lift bar is coupled to the lift bar 12 is installed with a press rod 11 is installed so that the bench press on the upper bar, the press rod 11 In addition, the tension is applied from the load applying means can be a bench press without a separate weight.

In particular, the bottom support (2) and the vertical support (3) is coupled to the rotation means can adjust the angle of the vertical support (3), which is installed in a semicircular shape on the back of the vertical support (3) and fixed a plurality of Leg part to fix the fixing bolt 15 together with the angle adjusting plate 14 in which the balls 13 are sequentially arranged, and the fixing hole 13 of the angle adjusting plate 14 corresponding to the fixing hole 13 mentioned above. It consists of a corresponding hole 16 formed in.

As shown in Figs. 4 and 5, the load applying means is fixed to the base 17 fixed to the bottom of the bottom support 2, and fixed to the fixing plate 18 inside the base 17 and is relatively long. The bobbin 19 formed in the length, the coil 21 wound around the bobbin 19 by a predetermined number of turns and supplied with current through the control unit 20, and inserted into the bobbin 19. And a plunger 22 which is movable and is also resisted by a magnetic force and receives a return force to be retracted, the rack gear 23 extending from the plunger 22 and protruding out of the bobbin 19, The rack gear 23 is composed of a tension means configured to move in accordance with the movement of the wire (W).

The tension means includes an idle gear 26 having a first gear 24 and a second gear 25 having a larger diameter than that of the rack gear 23 so as to rotate while being engaged with the rack gear 23; The drive gear 27 is installed to engage with the second gear 25 of one idle gear 26 and is interlocked with each other and is connected to each exercise device (chest press, press rod, upper rod, leg rod). It consists of a plurality of pulleys 28 provided so that the wires W are respectively wound, and power transmission means for intermittently cutting off / connecting the power so that the other exercise device does not operate when using one of the above-described exercise devices.

The idle gear 26 is coupled to the support base 28 and the shaft 29 so that both ends thereof are supported by the base 17 with a bearing or the like, and the first and second gears 24 of the idle gear 26 are described above. , 25 are different gear ratios, which is to increase the movement distance of the wire W (many rotational speeds of the pulley) even if the movement distance of the rack 23 is short.

Here, the bobbin 19, the coil 21, and the plunger 22 may be a solenoid, and a general solenoid may be manufactured in accordance with the capacity.

In addition, when the moving distance of the plunger 22 becomes short, the length of the bobbin 19 may be shortened, so that the overall length of the load applying means may be shortened.

The effect can be achieved even if the sizes of the bobbin 19 and the plunger 22 are sufficiently long without using the idle gear 26, the drive gear 27, and the pulley 28 described above.

The power transmission means is configured to be inserted into the polygonal (form capable of transmitting the rotational force) transmission hole 30 formed in the center of the plurality of pulleys 28, the transmission hole 30 and the idle gear (one end) 26 is coupled to the interlocking axis 29, the transmission projection 31 is formed in a portion of the shaft 29 is formed in a polygon so that only one pulley 28, and the shaft 29 It is composed of a handle 32 is fixed to and configured to pull it out by hand.

That is, when the handle 32 is pulled out or pushed by hand, only one of the pulleys 28 is engaged with the transfer hole 30 and the transfer protrusion 31, and the wire W is pulled as the exercise mechanism is pulled. By pulling the rack 23 through the idle gear 26, a load can be applied, and the rest is freely rotated (turns the wheel). Other sports equipment is not pulled.

The control unit 20 is a general circuit for adjusting the current of the solenoid, and the magnetic force adjustment knob installed therein is for controlling a general variable resistor and the like, and a detailed circuit diagram thereof will not be described.

The plunger 22 is formed to be substantially the same as the length of the bobbin 19, so that the self-centering force is generated as far from the bobbin 19, so that the exerciser does not use the force.

Here, the wire (W) and the roller (R) connecting the respective exercise mechanisms and the load applying means are to follow a general configuration, an example thereof is shown in FIG.

That is, each wire (W) is wound around a plurality of pulleys (28), the end of which is connected to each of the exercise equipment, the pulley 28 is rotated while the pulley 28 is rotated while holding the exercise equipment (22) is pulled out, which causes tension to be applied to each exercise device.

When explaining the operation and effect of the present invention as described above to sit on the seat (S) and pull or pull the handle so that the tension is applied to the desired exercise equipment and the transfer hole 30 of the desired exercise equipment pulley 28 and The transfer protrusion 31 of the shaft 29 is engaged.

By holding the handle 32 so as to apply the tension only to the desired exercise device, and by pulling the shaft 29 to adjust the intensity of the current in the control unit 20, the tension is adjusted to the state most suitable for them.

That is, when the current control knob (not shown) in the control unit 20 is adjusted, the current applied from the power supply is controlled by the control unit 20 and supplied to the coil 19, and thus, the coil 19 is supplied to the coil 19. By adjusting the amount of current (for example, using a variable resistor) it is possible to adjust the strength of the magnetic force generated in the coil 19.

When the desired load (tension) is matched, the exercise such as the chest press, bench press, leg curl, bar, etc. When the exercise through each of the above-described exercise equipment is connected to the wire (W) is pulled.

When the wire W is pulled, the pulley 28 on which the wire W is wound is rotated together, and the shaft is interlocked with the pulley 28, the transmission hole 30, and the transmission protrusion 31. As the 29 is rotated, the drive gear 27 is rotated.

When the drive gear 27 is rotated, the idle gear 26 engaged with the drive gear 27 rotates, so that the diameter of the second gear 25 of the idle gear 26 is larger than that of the drive gear 27. Because of the large number of teeth is slightly rotated compared to the drive gear 27 and the rack 23 is engaged with this only a little moving.

When the rack 23 is moved, the plunger 22 connected to the rack 23 is moved to receive the force of pulling the rack 23 backwards, so that the exerciser receives the resistance and thereby the exercise. You will be able to.

Here, the other pulleys 28 which do not move are not rotated together with the shaft 29 so that the wire W is not pulled.

As described above, the selected pulley 28 rotates as the wire W is pulled, and the driving gear 27 coupled thereto and the idle gear 26 engaged therewith rotate the rack 23. ) And the plunger 22 are moved while moving, it is not necessary to use a separate weight for the exercise equipment, it is very convenient to use the exercise equipment at home.

In addition, when describing the bench press, the athlete should be able to lie down by lying down on the vertical support 3 in order to perform the bench press. When the angle adjusting plate 14 is loosened and the vertical support 3 is completely flipped off, As the backrest S1 becomes horizontal, it becomes a part extending from the sheet S and can lie down.

When the head portion is positioned in the leg portion while lying on the seat (S), the press rod 11 is held by the hand and then lifted by the bar. This will rise and the wire (W) connected to it will be able to exercise.

That is, when the wire W rises, the wire W is smoothly guided and moved by the plurality of rollers R supporting the wire W, and the plunger 22 connected to the other end of the wire W is moved. As the pull W is wound while the wire W is wound, only the pulley 28 rotates, and the rack gear 23 moves as the driving gear 27 and the idle gear 26 connected to the pulley 28 rotate. While pulling the plunger 22.

When the athlete hears the press rod 11 and puts it down again, since the lifting rod 12 provided with the press rod 11 is fitted in the guide rod 10, the press bar is naturally lowered. When the rod 11 is missed or the load is too large, it is caught by the guide rod 10 even in a hurry so that the person who exercises does not get injured.

That is, conventionally, the bench press was put on the upper end of the "Y" shape and combined the heavy materials at both ends of the rod, but when the heavy weight is too heavy, when it is dropped or lifted, it loses its center or is dropped too suddenly. However, in the present invention, since the lifting rod 12 is stopped at a predetermined position by the guide rod 10, there is no fear of injury.

Here, when the frame 5 and the like is made of a material having excellent rigidity and light weight such as duralumin, etc., it is possible to carry, install, and move more comfortably when used for home use.

As described above, the present invention is configured to give a load by adjusting the magnetic force without using a weight, which is a weight used to give a load in a weight training exercise device, thereby greatly reducing the weight of the exercise device and simplifying the configuration. There is an advantage in removing the noise generated when the weight falls.

In addition, in the weight training exercise equipment that is used a lot in the home, by greatly reducing the weight, it is easy to move / install at home, there is an advantage that it is easier to use the weight training exercise equipment at home.

In addition, even if the athlete misses or suddenly lowers the press bar while the bench press is stopped by the guide bar and the lifting bar, there is an advantage of eliminating the risk of injury.
