Abstract

An exercise machine comprises a base 10, a seat rod 40 with a seat 41 at one end, and a pedal rod 50 with at least one pedal 51 at one end, the other ends of the rods being supported either in a box body 20 or in mounts (80,81, figures 7-9) so that the rods can swing back and forth about an axis extending longitudinally of the machine. When a box body is provided it preferably includes an upper plate 22 carrying a pair of spring pieces 23, 24 and a pair of upper locating blocks 25, 26 in each of which is formed a V-shaped slot 251, 261, and a lower plate 21 carrying a lower locating block 27 formed with a pair of V-shaped slots 271, 272. Braking blocks 42, 52 carried by the rods are located within one of the upper slots and one of the lower slots and are held therein by the spring pieces 23, 24 (figure 4). When mounts 80,81, figure 8) are provided then the rods carry tubes (45, 55, figure 8) which are inserted in the mounts with bolts (82, 83, figure 8) passing through holes in the mounts to pivotally fasten the rods in the mounts. The base may be formed of two parallel rods 101, 102, and the box body, which may have a cover 60, or the mounts are held between the parallel rods. The machine is capable of twirling the waist of a user.

As shown in FIGS. 1-5, an exercise machine embodied in the present invention comprises a base 10, a box body 20, a 3 seat rod 40, a pedal rod 50, a box cover 60.

The base 10 is rested on the ground and is formed of two locating rods 101 and 102 parallel to each other.

The box body 20 has a scat plate 21, which is fastened at both ends thereof with the two locating rods 101 and 102 of the base 10 by soldering. The seat plate 21 is provided on the top thereof with an inverted U-shaped plate 22 which has a top plate 221. The top plate 221 is provided in the center of the underside thereof with two locating spring pieces 23 and 24, which are fastened at one end thereof with the underside of the top plate 221 by soldering and are provided in the underside thereof with an upper locating block 25, 26. The locating blocks 25 and 26 are respectively provided with a V-shaped slot 251, 261. The pointed edges 2710 and 2720 are opposite in location to the two pointed edges 2510 and 2610 of the V-shaped slots 251 and 261 of the two upper locating blocks 25 and 26. An imaginary line 'W' is formed by connecting the pointed edges 2510 and 2710, whereas an imaginary line "B" is formed by connecting the pointed edges 2610 and 2720, as shown in FIGA. The seat plate 21 is further provided in the top thereof with two stop plates 28 and 29, which are opposite in location to the two V-shaped slots 271 and 272 of the lower locating block 27. The inverted U-shaped plate 22 is provided in a top plate 221 thereof with two bolts 30 and 31 which are fastened thereonto such that the two bolts 30 and 31 come in contact with the two locating spring pieces 23 and 24.

The seat rod 40 is fastened at outer end thereof with a seat pad 41, and at the inner end thereof with a braking block 42 4 which is provided with a lower tangent surface 421 and an upper tangent surface 422 and is inserted into the box body 20 such that the lower tangent surface 421 is inserted into the lower slot 271 of the lower locating block 27, and that the upper tangent surface 422 is inserted into the slot 251 of the upper locating block 25, thereby causing a pointed projection 4210 of the lower tangent surface 421 of the braking block 42 to come in contact with the pointed edge 2710 of the lower slot 271 of the lower locating block 27. The bolt 30 is fastened such that the bolt 30 presses against the first locating spring piece 23 to prevent the braking block 42 from becoming detached. The seat rod 40 is thus capable of swinging back and forth, as shown in FIGS. 5 and 6.

The pedal rod 50 is provided at the outer end thereof with a pedal pad 51, and at the inner end thereof with a braking block 52 which is in turn provided with a lower tangent surface 521 and an upper tangent surface 522. The braking block 52 is inserted into the box body 20 such that the lower tangent surface 521 of the braking block 52 is inserted into the lower slot 272 of the lower locatine, block 27, and that the upper tangent surface 522 of the braking block 52 is inserted into the upper slot 261 of the upper locating block 26, thereby causing a pointed projection 5210 of the lower tangent surface 521 of the braking block 52 to come in contact with the pointed edge 2720 of the lower slot 272 of the lower locating block 27, and thereby causing a pointed p rojection 5220 of the upper tangent surface 522 of the braking block 52 to come in contact with the pointed edge 2610 of the upper slot 261 of the upper locating block 26. The second bolt 31 is fastened onto the top plate 221 of the inverted U-shaped plate 22 so as to push the second locating spring piece 24 to move downward to prevent the braking block 5 2 of the pedal rod 50 from becoming detached. The pedal rod 50 is thus capable of swinging back and forth, as shown in FIGS. 5 and 6.

The box cover 60 is used to cover the box body 20.

As shown in FIGS.7-10, the exercise machine of the present invention further comprises a frame 70 which is fastened between the two locating rods 101 and 102 of the base 10. The frame 70 is provided with two mounts 80 and 81, which are respectively provided with a top plate 801, 811, and a bottom plate 802, 812, which are in turn provided with an upper through hole 8010, 8110, and a lower through hole 8020, 8120. An imaginary line "C" is formed by connecting the upper through hole 8010 and the lower through hole 8020, whereas an imaginary line "D" is formed by connecting the upper through hole 8110 and the lower through hole 8120, as shown in FIG. 9. The seat rod 40 and the pedal rod 50 are fastened respectively at the inner end thereof with a shaft tube 45, 55, which are respectively inserted into the two mounts 80 and 81. Two bolts 82 and 83 are inserted respectively into the two shaft tubes 45 and 55 vie the upper through holes 8010 and 8110 of the top seat plates 801 and 811 of the two mounts 80 and 81 such that the bottom ends of the two bolts 82 an 83 are inserted respectively into the lower throuah holes 8020 and 8120 of the bottom seat plates 802 and 812 of the two mounts 80 and 81. The seat rod 40 and the pedal rod 50 are fastened pivo tally with 6 the mounts 80 and 81 such that the seat rod 40 and the pedal rod 50 are capable of swinging back and forth, as shown in FIG. 10.

As shown in FIG. 11, the pedal rod 50 of the exercise machine of the present invention is provided at the outer end thereof with two pedals 90 fastened pivotally As shown in FIG. 12, the seat rod 40 of the exercise machine of the present invention is formed of a primary tube 401 and a secondary tube 402 which is provided in the side wall thereof with a plurality of holes 40-31 engageadle with a plurality of fastening bolts 404 by which the secondary tube 402 is detachably and adjustably fastened with the primary tube 401.

The exercise machine of the present invention has at least two advantages. In the first place, the present invention comprises the seat rod 40 and the pedal rod 50, which enable various parts of the body of an exerciser to be in action at the same time. The operations of the scat rod 40 and the pedal rod 50 are smooth in light of the pointed projections of the braking block 42 of the seat rod 40 and the braking block 52 of the pedal rod 50 are arranged on the two locating shaft lines 'W' and "B".
