Description:

BACKGROUND OF THE INVENTION

[0001] The present invention relates to healthy machine and more particularly to a belly exercise healthy machine.

[0002] Typical healthy machine for exercising the belly of human comprises generally a kneeling box, a roller assembly and a pair of elastic ropes connected between the kneeling box and the roller assembly. A human body kneels on the kneeling box and pushes the roller assembly forward. The body first displays to an inverse V-shaped posture, then gradually becomes a lying position as to stretch his belly and then pull back the roller assembly to regain his original kneeling posture. Repeated operation as discussed the above, it will achieve the belly exercise purpose. However, this type of the belly exercise healthy machine has a disadvantage that the elastic ropes may be disordered because they are all exploded out of the kneeling box.

SUMMARY OF THE PRESENT INVENTION

[0003] The present invention has a main object to provide a belly exercise healthy machine in which the elastic rope is hidden in the kneeling box and alternately wound on a plurality of wheels so that the rope is stretched or contracted freely without disordering.

[0004] Accordingly, the belly exercise healthy machine of the present invention comprises generally a kneeling box, a roller assembly and an elastic rope. The elastic rope has one end secured inside the kneeling box and alternately winds on five wheels and then the other end connects to the roller assembly. So that the elasticity of the elastic rope is stable and free to stretch and to contract without disordered.

[0005] The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] With reference to FIGS. 1, 2 and 3 of the drawings, the belly exercise healthy machine of the present invention comprises generally a kneeling box 10, an elastic rope 20 and a roller assembly 30. The kneeling box 10 has a cover 11, a base 12 combined with the cover 11 by a plurality of screws 111, three axial rods 121, 122 and 123 and a stabilized rod 129 spacedly disposed on the inner surface of the base 12, a front wheel 124 rotatably sleeved on the axial rod 121, a pair of the left wheels 125 and 126 superimposedly engaged on the axial rod 122, a pair of right wheels 127 and 128 superimposedly engaged on the axial rod 123, a back plate 120 projected upward from the back edge of the base 12 in which is a transverse linear slot 1201 and a plurality of L-shaped positioning slots 1202 communicating to the linear slot 1201 and a cushion 112 disposed on the top of the cover 11.

[0017] The roller assembly 30 has a shaft 31, a positioning plate secured to the middle portion of the shaft 31, a pair of rollers 33 rotatably secured to the shaft 31 abutting the lateral sides of the positioning plate 32, a pair of handle grips 34 wrapped on two ends of the shaft 31 and a pair of corks 35 secured to the free ends of the handle grips 34 (as shown in FIG. 4).

[0018] Referring to FIGS. 5 and 6 and FIGS. 1 and 2 again, the elastic rope has a first end secured to a ball headed adapter 23 which includes a circular plate 231, and a tube 24 has a hollow cylinder body 242, an opening 243 in the top and a collar 241 on one end for retaining the ball headed adapter 23. The tube 24 is secured to the positioning plate 32 by screw 25 and nut 321 with a washer engaged therebeween. The elastic rope 20 first winds on the front wheel 124, then a lower left wheel 126, a lower right wheel 128, an upper left wheel 125 and an upper right wheel 127 and then the second end of the rope secured to a ball headed adapter 21 which is retained in a cup shaped retainer 22. The retainer 22 has a retaining plate 221 secured to one end of the linear slot 1201 by a screw 222 and nut 223 with a washer engaged therebetween. The retaining plate 221 is displaceable to any of the L-shaped slots 1202 when the elastic rope 20 is found slack.

[0019] Referring to FIGS. 7 and 8, in operation, the operator knees on the top of the kneeling box 10 and grips the handle grips 34 to push the roller assembly 30 forward by using the force of the arms and the legs. The body of the operator is first bowed as an inverse V-shaped posture, then stretches out to became a lying position. When retreats, the elastic rope 20 will contract back into the kneeling box 10 and the body of the operator regains to his original kneeling posture. Repeated operation as discussed the above, the belly of the operator will be exercised.

[0020] Because of that the two right wheels 127 and 128 is rotated reversely to the left-wheels 125 and 126, the elastic rope 20 receives both the friction force and the resistance force so that rope 20 will be stretched or contracted stably and slowly.

[0021] Referring to FIGS. 9 and 10, an alternate embodiment of the belly exercise healthy machine is provided. This embodiment is structurally and functionally most similar to the above embodiment as described in FIGS. 1-8, and the above discussion is applicable in the most instances. The only difference is that the two rollers 33 of the roller assembly are removed. Instead of is a positioning clip 36 to clip the shaft 31 to control the positioning plate 32 from lateral displacement. By this modification, the operator may sit down on the top of the kneeling box 10 and lift the shaft 31 up and down with two hands just as to play a dumbbell.

[0022] The specification relating to the above embodiment should be construed as exemplary rather than as limitative of the present invention, with many variations and modifications being readily attainable by a person of average skill in the art without departing from the spirit or scope thereof as defined by the appended claims and their legal equivalents.
