1. Field of the Invention
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
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a multifunctional kinetic mechanism, which has the characteristics of simple structure, ease of operation and multimode operation capability, allowing training of different muscle groups.
To achieve this and other objects of the present invention, a multifunctional kinetic mechanism comprises a base, a counterweight unit, and an operating unit. The base comprises a slant tube. The counterweight unit comprises a joint shaft, a barbell shaft and a counterweight. The joint shaft is detachably connected to the slant tube of the base. The barbell shaft comprises a first end piece and an opposing second end piece. The first end piece is detachably connected to the joint shaft. The counterweight is detachably attached to the second end piece of the barbell shaft. The operating unit comprises a main frame, a sleeve, two opposing grips and two opposing shoulder cushion pads. The sleeve is mounted at the front side of the main frame and detachably sleeved onto the second end piece of the barbell shaft. The two grips are respectively pivotally mounted at the opposing rear side of the main frame. The two shoulder cushion pads are respectively mounted at the bottom side of the main frame between the sleeve and the two grips. Thus, the user can operate the operating unit to exercise different modes of operation, thereby training different muscle groups of the upper and lower limbs.
In one embodiment of the present invention, the joint shaft comprises a first joint member rotatably inserted into the slant tube of the base, and a second joint member vertically pivotally connected to the first joint member. Further, the first end piece of the barbell shaft is plugged into the second joint member. Thus, by means of the joint shaft, the barbell shaft can be operated to swing the counterweight at multiple angles.
In one embodiment of the present invention, the operating unit further comprises two auxiliary handlebars disposed at two opposite sides relative to the sleeve and respectively connected with respective one ends thereof to the bottom side of the main frame for gripping by the user's two hands to maintain operating stability when the two shoulder cushion pads are rested on the user's shoulders and the user is making the action of alternatively standing up and squatting down.
In one embodiment of the present invention, the counterweight unit further comprises an accessory rack disposed around the base. The accessory rack comprising an upright rod, a horizontal bar, and a support bar. After the user finished the operation, the user can rest the barbell shaft on the top end of the support bar, and then detach the operating unit and the counterweight from the barbell shaft, and then respectively attach the operating unit and the counterweight to one upright rods and one horizontal bar, and thus, the component parts storage is done.
Other advantages and features of the present invention will be fully understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference signs denote like components of structure.
Referring to
The base 20 is to be placed on the ground as a support. Structurally, the base 20 comprises at least one slant tube 22. The axis of each slant tube 22 defines with the ground a predetermined angle of inclination.
The counterweight unit 30 comprises a joint shaft 31, a barbell shaft 34, and a counterweight 38. The joint shaft 31 comprises a first joint member 32 and a second joint member 33. The first joint member 32 has a bottom end thereof rotatably inserted into one selected slant tube 22 of the base 20, and an opposing top end thereof vertically pivotally connected to a bottom end of the second joint member 33. The barbell shaft 34 comprises a first end piece 35 and an opposing second end piece 36. The barbell shaft 34 is inserted into the second joint member 33 of the joint shaft 31 by the first end piece 35. Thus, by means of the joint shaft 31, the barbell shaft 34 can swing at multiple angles. Further, the second end piece 36 of the barbell shaft 34 comprises a flange 37. The counterweight 38 has a center hole 39. By means of the center hole 39, the counterweight 38 can be attached onto the second end piece 36 of the barbell shaft 34 and stopped at the flange 37.
As illustrated in
After understanding the structure details of the multifunctional kinetic mechanism 10, the operation of the multifunctional kinetic mechanism 10 is explained hereinafter.
The first mode of operation is to maintain the standing posture facing toward the base 20, and then to hold the grips 45 of the operating unit 40 with the two hands, and then to lift and drop the two hands repeatedly, as shown in
The second mode of operation is to maintain the standing posture facing toward the base 20, and then to let the shoulder cushion pads 46 of the operating unit 40 be rested on the two shoulders, as shown in
Further, in order to facilitate storage, the counterweight unit 30 of the multifunctional kinetic mechanism 10 further provides an accessory rack 60, as shown in
When compared to conventional sports equipment, the multifunctional kinetic mechanism 10 of 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.
