Description

Magnetic training machine

The present invention relates to a magnetron training machine; in particular, to an innovative structural designer that can be used in a multi-functional manner and can effectively improve the working schedule.

According to the modern people, due to the fast pace of life and busy work, they are often neglected in sports. However, after the rise of leisure and health, the concept of exercise and fitness has also risen. The general movement is nothing more than a park or a school playground. Although such outdoor venues have the inherent advantages of good air vision, they are easily affected by the weather. Therefore, many manufacturers have developed a variety of sports and fitness equipment to Provide busy modern people to grasp the fragmentation time of the work space, and do not need to go outdoors to achieve the purpose of sports.

However, most commercially available exercise machines currently offer only a single function, which is weight training. If you want to buy sports machines with different functions for different training parts, even if your financial ability permits, there may not be enough space at home to accommodate these sports machines. Another shortcoming of the exercise exercise machine is the problem of insufficient stroke. At present, the weight training machine commonly used in the market usually uses a pull rope and a fixed pulley that changes the direction of the force to directly pull a damping mechanism; therefore, the drawstring The length of extension of the front end and the rear end is equivalent. However, due to the limited length of the rope that can be recovered in the damping mechanism, the length of the front end of the rope can be limited, and the movement stroke that can be provided during the operation is also Limited, so that users with longer body types can't Fully stretched, reducing exercise or training muscles. Moreover, in order to cooperate with providing a longer actuation stroke, the conventional exercise machine must continuously increase the diameter of the weight flywheel in order to be able to wind a longer distance rope. This will increase the weight of the counterweight flywheel. In addition to directly affecting the production cost of the exercise machine, the added weight also affects the transportation cost, and is even more likely to directly affect the consumer's willingness to purchase due to the difficulty of handling.

Traditional exercise machines usually use springs, elastic ropes or load blocks to provide greater load damping. It is hoped that consumers will see fitness effects in a short period of time. Especially in the sports center of the workshop, it is even more so to attract consumers. However, such a two-way operation mode is not the correct mode of motion. The reason is that when the user applies a force against the spring, the restoring force of the elastic rope or the gravity of the load block to perform the stretching action, the force must be continuously applied during the recovery. Avoid problems caused by momentary reset of springs, elastic ropes or load blocks, such as the noise generated by strong impact, the impact on the structure of the exercise machine itself, or even the danger of the user's physical strength.

As mentioned above, the existing training machines usually use a gravity load with a strong pullback effect, and the training target is focused on the muscle line exercise, so it is not suitable for young and old. What's more, some training machines are placed in the rehabilitation department of the hospital to provide the muscles for muscle strength or muscle rehabilitation, too strong gravity load and improper reaction force. I am afraid that the results of rehabilitation will not cause exercise. Injury, even unnecessary danger. Therefore, how to adjust the gravity load of the training machine to the most effective adjustment, and to provide different functions in the appropriate environment, such as muscle exercise or physical rehabilitation, and to expand the scope of the training machine, it is relevant. The industry will then consider the goals and direction of breakthroughs.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years, and after the detailed design and careful evaluation of the above objectives, it is true that The invention is practical.

The main object of the present invention is to provide a sports fitness device, and the technical problem to be solved is to make an innovative breakthrough in how to develop a new type of magnetron training machine structure which can effectively improve the working stroke.

The technical feature of the present invention is mainly to the magnetic control training machine, comprising a base; a damping device mounted on the base; a pulley block connected to the damping device, the pulley block comprising a movable pulley; the damping device is The utility model comprises a weight flywheel screwed on the base, a magnetron wheel which is arranged on the base and a reset device connected to the weight flywheel; a first cable which is arranged on the pulley assembly pulley; the first pull The first end and the second end of the rope are respectively provided with a first pull handle and a second pull handle, wherein the original height of the first pull handle is higher than the original position of the second pull handle; and one is connected to The second drawstring of the pulley block and the damping device.

By virtue of the unique position of the movable pulley, the present invention can provide a greatly shortened extension stroke of the connecting damper of the connecting damper, and utilizes the magnetron wheel, in addition to providing more than one machine for comparison with the prior art. It avoids the unnecessary reaction force when the damping device recovers, and thus achieves the purpose of reducing the diameter of the weight flywheel and the magnetron wheel. For the function, it can provide the rehabilitation of the elderly or related muscles for the purpose of magnetic training. In terms of the structure of the machine body, it can provide practical improvement of the body weight reduction, reduction of manufacturing cost and transportation cost, and better industrial economy (utilization) benefit.

The pulley block 20 includes a stand 21 that is fixedly mounted on the base 10, and the stand 21 is disposed between the damper device 30 and the seat 80. A first fixed pulley 22 and a second fixed pulley 23 are respectively disposed at two ends of the top of the vertical frame 21. The rear side of the vertical frame 21 is sequentially provided with a third fixed pulley 24 and a fourth fixed portion from top to bottom. Pulley 25. The first pull cord 40 is sequentially wound around the first fixed pulley 22, the second fixed pulley 23, and the third fixed slip. The wheel 24 and the fourth fixed pulley 25 are disposed around the second fixed pulley 23 and the third fixed pulley 24 . The second pull cord 70 is connected to the movable pulley 26 , and the second pull cord 70 is disposed with a weight 71 between the movable pulley 26 and the damper device 30 . Referring to FIG. 3, the level of the third fixed pulley 24 is smaller than the horizontal height of the first fixed pulley 22 and the second fixed pulley 23, respectively.

The damper device 30 includes a weight flywheel 31 that is screwed on the base 10, a magnetron wheel 32 that is screwed onto the base 10, and a reset device 33 that is connected to the weight flywheel 31. The second end of the second pull cord 70 is attached to the counterweight flywheel 31 after being wound around the counterweight flywheel 31. The first side of the counterweight flywheel 31 is coupled to the magnetron 32 by a belt 311, and the second side of the counterweight flywheel 31 is concentrically provided with a wire take-up device 35, and the wire take-up device 35 is wound There is a pull cord 312, and the drawstring 312 is coupled to the resetting device 33, wherein a one-way bearing 321 is further mounted at the center of the magnetron wheel 32. The damper device 30 further includes a fixed pulley 34 disposed on the base 10 and vertically corresponding to the movable pulley 26, and the fixed pulley 34 is used to change the biasing direction of the second cable 70. The weight 71 is disposed between the movable pulley 26 and the fixed pulley 34. The weight provided by the weight 71 is greater than the sum of the gravity of the first or second handle 50 or the second handle 60 and the friction of the pulley block 20.

Referring to FIG. 4, it is a reference diagram of the first use state of the present invention. In this embodiment, the user sits on the seat 80 facing the pulley block 20, and then lifts the upper arm to grasp the first. Pulling the two ends of the handle 50, and then pulling the first pull cord 40 hard, using the reaction force provided by the damping device 30 to achieve the effect of exercising the upper arm; such a manner can also take the sitting posture of the back pulley block 20 (not shown) ) Execution, the muscles of other parts of the upper arm can be exercised, so that the lines of the upper arm and chest muscles of the user are better symmetrical. As shown in FIG. 5, the user can also sit on the seat 80 in the manner of facing the pulley block 20. The second pull handle 60 is pulled in a backward manner, and the effect of lifting the abdominal muscles can be obtained. The above description provides the function of the multi-function of the invention, and in addition to improving the added value of the exercise machine itself, of course, the purchase intention of the consumer is relatively increased.

When the user pulls the first pull handle 50 or the second pull handle 60, the movable pull pulley 26 is driven upward through the first pull cord 40 and the second pull rope 70 is pulled to drive the counterweight flywheel 31 to make the weight in the rotation. The flywheel 31 rotates the magnetron wheel 32 by the belt 311, so that the damper mechanism 30 can provide a damping effect of an appropriate strength by utilizing the interlocking relationship between the weight flywheel 31 and the magnetron wheel 32. The rotating weight flywheel 31 drives the wire take-up device 35 and stretches the reset device 33 through the pull wire 312 to facilitate the resetting of the first pull handle 50 or the second pull handle 60 by using the wire take-up device 35. The second pull cord 70 is wound up to drive the counterweight flywheel 31.

Referring to Fig. 6, the pulley block 20 of the present invention is provided with a movable pulley 26. However, as long as the resistance provided by the damping device 30 is large enough, the motion benefit that the magnetron training machine can provide is not reduced at all. The main purpose of the present invention is to add the movable pulley 26 to the pulley block 20, which is to consider the weight reduction and cost of the mechanism. As can be clearly seen from FIG. 6, when the user pulls the first pull cord 40 by the distance L by the first pull handle 50 at the front end of the pulley block 20, since the other end of the first pull cord 40 is affected by the The limiting action of the second pull handle 60 causes the movable pulley 26 to move only half of the distance L; in other words, the second pull cord 70 also moves only half of the distance L, so in the case of providing the same movement stroke and the amount of movement, The stroke of the second pull cord 70 is halved. By the invention, the technical characteristics of the work stroke are effectively improved, so that the diameters of the weight flywheel 31 and the magnetron wheel 32 can be greatly reduced, so that the weight flywheel 31 and the magnetic control wheel can be reduced. The material cost of 32 can provide the purpose of lightweighting the magnetron training machine, and it can indirectly reduce transportation costs and share profits with consumers. On the other hand, when the user moves the first rope by the second pull handle 60 at the rear end of the pulley block 20, the other end of the first pull cord 40 is subjected to the first pull handle 50. The limit action causes the movable pulley 26 to move only half of the distance L, and also has the effect of effectively improving the working stroke. In summary, please refer to the second, fifth, and sixth figures, the moving stroke of the movable pulley 26 is smaller than the original (unactuated) distance between the third fixed pulley 24 and the movable pulley 26. Furthermore, in addition to improving the exercise load of the present invention, the weight 71 can be used with the weight of the weight 71 itself to match the reset function provided by the damper 30 itself, and the first handle 50/ after use is used. The second pull handle 60 is brought back to its original position and is snapped onto the stand 21 for convenient use.

Please refer to the figures shown in Figures 3, 4 and 5. This creation mainly uses the magnetic control wheel generally used for exercise bikes to be used in training machines to achieve the rehabilitation function that the training machine cannot provide. Since the magnetron structure (magnet wheel 32) provides an appropriate damping effect only when the user pulls the first pull handle 50 or the second pull handle 60, when the first pull handle 50 or the second pull handle 60 is reset, The magnetron 32 does not generate any reverse pulling force on the second pull cord 70; the resetting mechanism of the first pull handle 50 and the second pull handle 60 mainly utilizes the gravity pulling of the weight 71 itself. Pulling the rope 40, slowly pulling the used first pull handle 50 or the second pull handle 60 back to the original position, and when the first pull handle 50 or the second pull handle 60 is reset, the magnetic control wheel 32 cannot provide any The reverse pulling force is such that the resetting device 33 that is stretched during the actuating, by its restoring force, reversely drives the counterweight flywheel 31 to retract the slack second pulling cord 70.

Due to the unpredictable effects of the aforementioned magnetron 32 applied to the training machine, the present invention has the function of limb rehabilitation. It mainly reduces the damping effect provided by the magnetron 32 or reduces the weight of the weight 71, and adjusts the damping effect provided by the overall mechanism to the needs or limits of the patient according to the recommendation of the rehabilitation physician. The more moderate exercise mode meets the needs of patients' rehabilitation, thereby expanding the scope and added value of the training machine.
