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.
[0029] With reference to FIGS. 1 and 2, when the adjustment pin 23 of each cable and pulley
assembly 20 is pulled out from the first sliding seat 22 of the respective cable and
pulley assembly 20, the height of the first sliding seat 22 relative to the adjustment
tube 21 can be adjusted by sliding the first sliding seat 22 along the length of the
adjustment tube 21. After a desired height of the first sliding seat 22 relative to
the adjustment tube 21 is reached, the adjustment pin 23 is then inserted into the
first sliding seat 22 and the corresponding height adjustment hole 211 to fix the
first sliding seat 22 to the adjustment tube 21. Hence, since the height of the first
sliding seat 22 of each cable and pulley assembly 20 can be adjusted, a prestressed
force provided by each tension rope unit 80 to the cable member 60 of each cable and
pulley assembly 20 can also be adjusted.
[0030] 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.
[0031] With reference to FIGS. 2 and 4, when the first end 61 of the cable member 60 is
positioned on the second positioning plate 333 through the retaining ball 613 and
through the insertion of the insert pin 612 into the pair of second pin holes 334
of the second fixing member 332 and the hole in the fastening piece 611, the second
end 62 of the cable member 60 is retained externally of the pivoting member 222 through
the retaining ball 621, and the intermediate section 63 of the cable member 60 is
looped around the the lower pulleys 26, the second upper pulleys 25, the counterweight
pulley 522 and the first upper pulleys 24. Through this, the first sliding seat 22,
the first end 61 of the cable member 60, the lower pulleys 26, the second upper pulleys
25, the counterweight pulley 522, the first upper pulleys 24, and the second end 62
of the cable member 60 disposed on each side frame portion 12 form a loop.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] Referring to FIG. 6, the second embodiment of the fast-switching comprehensive training
device 100 of this disclosure differs from the first embodiment in that each counterweight
unit 50' includes a plurality of the tension rope selection racks 51' sleeved on the
selection rod 52 and the pair of counterweight guide rods 13, and the selection pin
54 is removably inserted into a selected one of the tension rope selection racks 51'
and a corresponding one of the insertion holes 523 (see FIG. 2) in the selection rod
52. The counterweights 53 (see FIGS. 1 and 2) are not provided in this embodiment.
Each tension rope selection rack 51' is similarly provided with a pair of hangers
511 at the two opposite sides thereof. Each tension rope 81 of the tension rope unit
80 has the one end hooked to one of the fixing holes 1241 in a corresponding one of
the fixed plates 124, and the other end hooked to one of the hangers 511 of a corresponding
one of the tension rope selection racks 51'. Each pair of counterweight guide rods
13 is fixedly connected with a pair of cushion pads 14. The second embodiment can
achieve the same operation purpose and fitness effect as the first embodiment.
[0037] The operation of this disclosure is described below.
[0038] Referring to FIGS. 7 and 8, in combination with FIG. 4, when the first end 61 of
the cable member 60 of each cable and pulley assembly 20 is positioned on the second
fixing member 332 of the corresponding second sliding seat 33, and each hook member
34 is removed from the corresponding hanging hole 1231, the user can perform a squat
exercise, as shown in FIG. 7, and a dead lift exercise, as shown in FIG. 8. During
use, each second sliding seat 33 is slidable along the length of the respective sliding
guide rod 32, and with the middle section 63 of the cable member 63 of each cable
and pulley assembly 20 looping around the respective counterweight pulley 522 so that
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 Smith machine exercises
can be performed by the user.
[0039] Referring to FIGS. 9 to 18, in combination with FIG. 5, when the comprehensive training
device 100 of this disclosure is switched from the Smith machine exercise mode to
the cable machine exercise mode, the first end 61 of the cable member 60 of each cable
and pulley assembly 20 is positioned on the first fixing member 224 of the first sliding
seat 22 of the corresponding cable and pulley assembly 20, each hook member 34 is
hooked to a selected one of the hanging holes 1231, and the height of the first sliding
seat 22 of each cable and pulley assembly 20 is adjusted by the user according to
his requirement. In cooperation with the different handles 70 connected to the second
end 62 of the cable member 60 of each cable and pulley assembly 20, the cable member
60 can be driven when the handle 70 is pulled, and with the middle section 63 of the
cable member 63 of each cable and pulley assembly 20 looping around the counterweight
pulley 522 of the corresponding counterweight unit 50 so as to move the same, and
through the weight of each counterweight unit 50 and the elasticity of each tension
