  • the primary objective of the present invention is to provide a weight training machine having a selector device that is operated easily and conveniently.
  • Another objective of the present invention is to provide a weight training machine, wherein the pull wire of the reel is kept at a straight state constantly during movement of the selector, so that the pull wire of the reel will not interfere with operation of the selector and will not tangle with the weights, thereby facilitating the user operating the selector, and thereby protecting the user's safety.
  • a further objective of the present invention is to provide a weight training machine, wherein the two retaining plugs of the selector are retained in the respective retaining groove of the drive shaft, and the clamping opening of the selector is clamped on the drive shaft, so that the selector is combined with the drive shaft rigidly and stably, thereby facilitating the user operating the selector to move the weights smoothly.

  • Fig. 2 is a perspective view of a selector device of the weight training machine as shown in Fig. 1.
  • Fig. 3 is an exploded perspective view of the selector device of the weight training machine as shown in Fig. 2.
  • Fig. 4 is a partially enlarged view of the weight training machine as shown in Fig. 1.
  • Fig. 5 is a partially plan cross-sectional view of the weight training machine as shown in Fig. 4.
  • Fig. 6 is a schematic operational view of the weight training machine as shown in Fig. 4.
  • Fig. 7 is a schematic operational view of the weight training machine as shown in Fig. 6.
  • Fig. 8 is a partially perspective view of a conventional weight training machine in accordance with the prior art.
  • Fig. 9 is a schematic operational view of the conventional weight training machine as shown in Fig. 8.
  • a weight training machine in accordance with the preferred embodiment of the present invention comprises a support frame 9, and a selector device mounted on the support frame 9.
  • the support frame 9 includes an arc-shaped post 91, an upright post 92 having an upper end connected with an upper end of the arc-shaped post 91, a transverse post 90 mounted between lower ends of the arc-shaped post 91 and the upright post 92, two parallel guide rods 93 mounted between the arc-shaped post 91 and the transverse post 90, a plurality of weights 4 movably mounted on the two guide rods 93, a drive shaft 53 movable between the two guide rods 93 and extended through each of the weights 4 to move the weights 4 upward and downward, a drive belt 95 mounted on the drive shaft 53 to move the drive shaft 53, a support plate 50 movably mounted on the two guide rods 93 and rested on an uppermost one of the weights 4, an operation plate 5 movably mounted on the two guide rods 93 and located above the support plate 50, two mounting tubes 51 each movably mounted on a respective one of the two guide rods 93 and each located between the operation plate 5 and the support plate 50, and
  • the drive shaft 53 of the support frame 9 has an outer wall formed with a plurality of annular retaining grooves 54 as shown in Fig. 5.
  • the positioning plate 6 of the support frame 9 is substantially U-shaped and has two distal ends each secured to the support plate 50 by a locking screw 62.
  • the positioning plate 6 has a mediate portion formed with an elongated stop slit 61.
  • the selector device includes a selector 2 that is inserted into a gap 40 between any two adjacent weights 4 and connected to the drive shaft 53 to move determined weights 4, and a reel 1 mounted on the selector 2 and having a retractable pull wire 13 having a distal end secured to the support frame 9 so that the pull wire 13 of the reel 1 is kept at a straight state constantly when the selector 2 is connected to the drive shaft 53.
  • the selector 2 is substantially Z-shaped.
  • the selector 2 has a first portion formed with an operation plate 22 that is inserted into the gap 40 between any two adjacent weights 4 and connected to the drive shaft 53, a mediate portion formed with an upright section 26 and a second portion formed with a flat plate 20.
  • the operation plate 22 of the selector 2 has a forked distal end formed with two opposite retaining plugs 23 inserted into and retained in either one of the retaining grooves 54 of the drive shaft 53 to secure the operation plate 22 to the drive shaft 53, and a clamping opening 25 located between the two retaining plugs 23 to clamp the drive shaft 53.
  • the upright section 26 of the selector 2 is formed with two threaded locking holes 27.
  • the flat plate 20 of the selector 2 is formed with a through hole 200 and has a distal end provided with a handle 21 parallel with the upright section 26 to facilitate a user operating the selector 2.
