Referring to
The cable member 60 has a first end 61, a second end 62 opposite to the first end 61, and an intermediate section 63 connected between the first and second ends 61, 62. The retaining unit includes a retaining ball 613 connected to the first end 61, a fastening piece 611 fixed on top of the retaining ball 613, and an insert pin 612. The intermediate section 63 is looped around the lower pulleys 26, the second upper pulleys 25, a counterweight pulley 522 of the counterweight unit 50, and the first upper pulleys 24. The second end 62 passes between the pair of pulleys 223, and is connected with a retaining ball 621 to retain externally of the pivoting member 222 for connection with one of the handles 70.
The barbell unit 30 includes two sliding guide rods 32, two second sliding seats 33, an exercise bar 40 and two hook members 34. Each sliding guide rod 32 is connected between the pair of second upper pulley brackets 128 and the pair of lower pulley brackets 129, and is parallel to and located between the vertical rod 123′ and the adjustment tube 21.

The one side of the first sliding seat body 221 is distal to a corresponding one of the sliding guide rods 32. That is, the pivoting member 222 is located distal to the corresponding sliding guide rod 32.
The first end 61 of the cable member 60 is movable between a first position and a second position. In the first position, as shown in
The insert pin 612 of the retaining unit is configured for positioning the first end 61 of the cable member 60 in the first position or the second position.
Specifically, the insert pin 612 is removably inserted into the pair of first pin holes 226 and a hole in the fastening piece 611 to position the first end 61 of the cable member 60 at the first position, and is removably inserted into the pair of second pin holes 334 and the hole in the fastening piece 611 to position the first end 61 of the cable member 60 at the second position. The retaining ball 613 abuts against the first positioning plate 225 when the first end 61 of the cable member 60 is at the first position, and abuts against the second positioning plate 333 when the first end 61 of the cable member 60 is at the second position.
The exercise bar 40 has two opposite ends connected fixedly and respectively to the second sliding seat bodies 331 of the second sliding seats 33. The hook members 34 are rotatably disposed on the exercise bar 40 in proximity to the two opposite ends thereof. Each hook member 34 is removably hooked to a selected one of the hanging holes 311 in the vertical rod 123′ of the respective side frame portion 12 so as to position each second sliding seat 33 relative to the vertical rod 123′ of the respective side frame portion 12 and a corresponding one of the sliding guide rods 32.
The counterweight units 50 are respectively disposed on the side frame portions 12, and are respectively movable along the pairs of counterweight guide rods 13. Each counterweight unit 50 includes a tension rope selection rack 51 sleeved on a corresponding one pair of the counterweight guide rods 13, a selection rod 52 inserted into the tension rope selection rack 51 at a central portion thereof and transverse to the bottom rod 121 and the top rod 122, a plurality of counterweights 53 sleeved on the selection rod 52 and the corresponding one pair of the counterweight guide rods 13, and a selection pin 54. The tension rope selection rack 51 has a pair of hangers 511 located at two opposite sides thereof which respectively face the vertical rods 123, 123′. The selection rod 52 has a plurality of insertion holes 523 spaced apart from each other along a length thereof, and a pulley bracket 521 disposed on top thereof. The counterweight pulley 522 is pivotally connected to the pulley bracket 521. Each counterweight 53 has a rectangular shape, and is formed with a through hole 531 at a central portion thereof and extending in a width direction thereof. The selection pin 54 is removably inserted into the through hole 531 of a selected one of the counterweights 53 and a corresponding one of the insertion holes 523 in the selection rod 52.
The handles or handgrips 70 are removably and selectively connected to the second ends 62 of the cable members 60, and may include two triangular handgrips, a short grip bar, a U-shaped handgrip, a long grip bar, etc.
Each tension rope unit 80 includes a plurality of tension ropes 81 equally disposed on the two opposite sides of the tension rope selection rack 51. Each tension rope 81 has one end hooked to one of the fixing holes 1241 in a corresponding one of the fixing plates 124, and the other end which may be selectively hooked to one of the hangers 511 or one of the storage hooks 125. That is, during exercise, the other end of each tension rope 81 is hooked to one of the hangers 511 so that each tension rope 81 can provide an elastic resistance. Because each user needs different elastic resistance, the number of the tension ropes 81 hooked to the hangers 511 may be adjusted. The other ends of the tension ropes 81 that are not needed may be hooked to the corresponding storage hooks 125.
With reference to
Further, when a user pulls the handles 70, through the intermediate section 63 of the cable member 60 of each cable and pulley assembly 20 that loops around the counterweight pulley 522 of the corresponding counterweight unit 50, each counterweight unit 50 can be moved, and through the weight of each counterweight unit 50 and the elasticity of each tension rope unit 80, the first exercise mode can be performed. At this time, the barbell unit 30 is not connected to the counterweight units 50.
With reference to
When the height of each second sliding seat 33 relative to the respective sliding guide rod 32 is adjusted, and each hook member 34 is hooked to a selected one of the hanging holes 1231, each second sliding seat 33 can be fixed to the respective sliding guide rod 32 at a desired height. Since the height of each second sliding seat 33 can be adjusted, the prestressed force provided by each tension rope unit 80 to the cable member 60 of the respective cable and pulley assembly 20 can also be adjusted.
When each hook member 34 is removed from the selected one of the hanging holes 1231, and the user pulls the exercise bar 40, through the intermediate section 63 of the cable member 60 of each cable and pulley assembly 20 that loops around the counterweight pulley 522 of the corresponding counterweight unit 50, each counterweight unit 50 can be moved, and through the weight of each counterweight unit 50 and the elasticity of each tension rope unit 80, the second exercise mode can be performed. At this time, since the length of the cable member 60 of each cable and pulley assembly 20 is fixed, it is not advisable to use the cable and pulley assemblies 20.
Therefore, through the configurations of the cable and pulley assemblies 20 and the barbell unit 30, and with the first end 61 of the cable member 60 of each cable and pulley assembly 20 being able to be moved and positioned on the first fixing member 224 or the second fixing member 332, the comprehensive training device 100 of this disclosure can be quickly switched between the first exercise mode and the second exercise mode. To switch between the exercise modes, it is only necessary to pull out the insert pin 612 from one of the pair of first pin holes 226 and the pair of second pin holes 334 and then insert it to the other one of the pair of first pin holes 226 and the pair of second pin holes 334. By combining two devices into one, this disclosure has a reduced cost, and does not occupy a substantial area.
Furthermore, according to the needs of the user, the selection pin 54 can be inserted into the through hole 531 of a selected one of the counterweights 513 and a corresponding one of the insertion holes 523 in the selection rod 52, and the number of the tension ropes 81 can be selected by hooking each tension rope 81 between one of the hangers 511 and one of the fixing holes 1241 in the corresponding fixed plate 124.
