The present invention relates to exerciser technology and more particularly, to a multifunctional kinetic mechanism.

2. Description of the Related Art

In order to maintain good health and body shape, enhanced leg weight training has great benefits on the support of the upper body. A typical leg exercise, such as squat, is normally trained using a weightlifting rack, however, it should be very careful when using a weightlifting rack to do a lunge or calf-raise exercise.

Due to the factors that outdoor sports require an appropriate venue and are easily be affected by the weather and the factor that people are busy with work and have only limited time to spend for exercise, going to the gym has become a trend.

However, most conventional sports machines simply provide one single mode of operation. If you want to exercise different muscle groups, you must use different functions of sports machines; in consequence, the gym owner will encounter the problems of space crowding and increased costs of purchased equipment.

On the other hand, many people are eager to involve in the sports activity of triathlon, long-distance running or long-distance cycling in recent years, therefore, they attach great importance to the training of the leg muscles, especially the thigh muscles. In order to solve the problem of thigh training, leg squat weightlifting systems are created. For example, Taiwan Patent No. 1357342 discloses a weightlifting system that allows the user to make a leg squat operation safely in one machine, enabling the muscle groups of the legs to be effectively trained. However, this design of weightlifting system is complicated in structure, and its operation is dull and boring, and therefore, in practical terms, this design of weightlifting system is not user friendly and there is room for improvement

DETAILED DESCRIPTION OF THE INVENTION

Referring toFIGS. 1-5, a multifunctional kinetic mechanism10in accordance with a first embodiment of the present invention is shown. The multifunctional kinetic mechanism10comprises a base20, a weight-bearing mechanism30, and an operating bar40.

The base20is to be placed on the ground as a support. Structurally, the base20comprises at least one slant tube22. The axis of each slant tube22defines with the ground a predetermined angle of inclination.

Referring also toFIG. 3, the weight-bearing mechanism30comprises a joint shaft31, a barbell shaft34, and a counterweight38. The joint shaft31comprises a first joint member32and a second joint member33. The first joint member32has a bottom end thereof rotatably inserted into one selected slant tube22of the base20, and an opposing top end thereof vertically pivotally connected to a bottom end of the second joint member33. The barbell shaft34comprises a first end piece35and an opposing second end piece36. The barbell shaft34is inserted into the second joint member33of the joint shaft31by the first end piece35. Thus, by means of the joint shaft31, the barbell shaft34can swing at multiple angles. Further, the second end piece36of the barbell shaft34comprises a flange37. The counterweight38has a center hole39. By means of the center hole39, the counterweight38can be attached onto the second end piece36of the barbell shaft34and stopped at the flange37. The operating bar40comprises a large shaft portion41, and a small shaft portion42axially connected to one end of the large shaft portion41. The large shaft portion41of the operating bar40is sleeved onto the second end piece36of the barbell shaft34, and locked thereto by a locking member44(for example, finger screw). The operating bar40further comprises a spherical grip43connected to one end of the small shaft portion42remote from the large shaft portion41for convenient gripping by a user.

After understanding the structure details of the multifunctional kinetic mechanism10, the operation of the multifunctional kinetic mechanism10is explained hereinafter.

The first mode of operation is to maintain the standing posture facing toward the base20, and then to hold the small shaft portion42of the operating bar40with one hand, and then to lift and drop the arm repeatedly, as shown inFIG. 4andFIG. 5. When lifting and dropping the arm, the barbell shaft34is alternatively biased up and down with the joint shaft31relative to the base20, and at the same time, the counterweight38gives a pressure to the arm, enabling the upper limb muscles to be well trained.

The second mode of operation is to attach a cushion sleeve50onto the small shaft portion42of the operating bar40for improving operation comfort, and then to maintain the standing posture facing toward the base20, and then to support the small shaft portion42of the operating bar40on one shoulder, as shown inFIG. 6andFIG. 7, and then to repeat the action of alternatively standing up and squatting down, and at the same time, the counterweight38gives a pressure to the shoulder, enabling the lower limb muscles to be well trained.

The third mode of operation is to stand in a sideward-facing position relative to the base20, and then to hold the spherical grip43of the operating bar40with one hand, and then to exercise the lunging action, as shown inFIG. 8. At this time, the barbell shaft34is alternatively biased left and right with the joint shaft31relative to the base20.

During this operation, and at the same time, the counterweight38gives a pressure to the arm, enabling the upper limb muscles to be well trained.

In operation, in addition to training the lower limb muscles, the arm holding the operating bar40will also get well trained subject to the effect of the counterweight38.

Further, in order to facilitate storage, the weight-bearing mechanism30of the multifunctional kinetic mechanism10further provides an accessory rack60, as shown inFIGS. 1, 2 and 9. The accessory rack60is placed around the base20.

Structurally, the accessory rack60comprises a plurality of upright rods61(actually, one single upright rod is enough), a plurality of horizontal bar62(actually, one single horizontal bar is enough), and one support bar63.

After the user finished the operation, rest the barbell shaft34on the top end of the support bar63, and then detach the operating bar40and the counterweight38from the barbell shaft34, and then respectively attach the operating bar40and the counterweight38to one upright rods61and one horizontal bar62, and thus, the component parts storage is done.

When compared to conventional sports equipment, the multifunctional kinetic mechanism10of the present invention has the advantages of simple structure, ease of operation and multimode operation capability, allowing the user to train different muscle groups according to personal needs.
