Abstract

An adjustment assembly for a universal exercising machine includes two blocks respectively adapted to have resilient rods to be mounted thereon and being movable relative to the frame and each block having a first pathway and a second pathway to respectively allow extension of an adjustment device and a securing bolt and nut combination and two adjustment disks to sandwich therebetween the two blocks. Each adjustment disk has two sets of openings respectively defined in two opposed sides of the adjustment disk and two passages respectively provided to communicate with one set of openings. Each opening has a dimension larger than that of the passage so that when the adjustment device is selectively received in the passage, the blocks are able to be moved relative to the frame.

Claims

1. An adjustment assembly for a universal exercising machine having a frame, two groups of resilient rods respectively connected to the frame in two different directions and two handle cables respectively extending from two corresponding resilient rods, the adjustment assembly comprising:

two blocks respectively adapted to have the resilient rods to be mounted thereon and being movable relative to the frame and each block having a first pathway and a second pathway to respectively allow extension of an adjustment device and a securing stud and nut combination;

two adjustment disks to sandwich therebetween the two blocks, each adjustment disk having two sets of openings respectively defined in two opposed sides of the adjustment disk and two passages respectively provided to communicate with one set of openings, wherein each opening has a dimension larger than that of the passages,

wherein the adjustment device has a first shank and a second shank securely connected to the first shank, the first shank has a dimension larger than that of the passage yet smaller than that of the openings, a first head formed on an end of the first shank and a neck formed between the first shank and the first head and having a dimension smaller than that of the passage so that when the first shank is received in a corresponding one of the openings, the first shank is immovable relative to the two adjustment disks and when the neck is received in the passage, the first shank is movable relative to the two adjustment disks,

the second shank has a second head, a flange formed between the second head and the second shank and having a dimension larger than that of the passage yet smaller than the openings and a recoil spring mounted around the second shank and abutted between an inner periphery defining the opening and a face of the first shank, the second shank has a dimension smaller than that of the passage such that when the flange is received in a corresponding one of the openings, the second shank is immovable relative to the two adjustment disks and when the second shank is received in the passage, the second shank is movable relative to the two adjustment disks, so that when the adjustment device is selectively received in the passage, the blocks are able to be moved relative to the frame.

2. The adjustment assembly as claimed in claim 1, wherein the first shank further has a path defined in an end of the first shank opposite to the first head and the second shank has a threaded end formed on an end of the second shank opposite to the second head to correspond to the path so that the threaded end of the second shank is able to threadingly extend into the path to secure engagement between the first shank and the second shank.
