Description

[0001] This application is a divisional application of the invention patent application with application number "202111437972.3", application date of November 30, 2021, and invention name "A comprehensive upper limb muscle strength training system". Technical Field

[0002] The present invention relates to the field of rehabilitation training equipment, and in particular to an upper limb muscle strength comprehensive training system. Background Art

[0003] As people age, their bodily functions undergo physiological aging, with degenerative changes in muscles being particularly pronounced, severely impacting their quality of life. Strength training is an effective countermeasure against muscle weakness, increasing joint flexibility and improving the body's response to exercise, cardiovascular, and psychological function. It can also effectively increase bone stress in the elderly, preventing osteoporosis, and improving static balance, reducing the risk of falls and effectively preventing disease.

[0004] Currently, there are many types of muscle strength training equipment available. First, the sports rehabilitation therapy equipment and sports training equipment commonly used in clinical rehabilitation are mainly used for patients with limb motor function loss or impairment, such as various passive or active-passive hybrid joint movement training equipment, rehabilitation training robots, etc. These devices include joint movement training, muscle strength training, etc., and are mainly used for rehabilitation training and treatment of patients in the limb function recovery stage due to cerebrovascular and nerve injuries. The equipment structure is relatively complex, the technical content is high, and the price is relatively expensive.

[0005] In addition, muscle strength training equipment for rehabilitation exercises for people with weak muscle strength, such as the elderly, is generally used in nursing homes, welfare institutions, rehabilitation centers, communities, etc., to meet the muscle strength training needs of elderly people with self-care ability or semi-disabled elderly people. This type of equipment includes various types of equipment for training different parts of the human body, such as the upper and lower limbs, trunk, waist, chest, back, etc. A single device is generally used to train a single part or muscle group. If multi-part training of the whole body is required, multiple devices need to be involved, and switching between multiple devices is required during training. This type of equipment is relatively simple to operate and inexpensive, but this type of equipment has problems such as a single function of a single set of equipment, a large space occupied by the equipment required for combined training, a monotonous training process, and no feedback on the training effect. As a result, the elderly lack the enthusiasm to continue to participate in rehabilitation exercises, the equipment utilization rate is low, and the elderly and other people with reduced muscle strength cannot achieve the goal of strengthening their limb muscle strength. Therefore, there is currently a lack of muscle strength training equipment that is truly suitable for the elderly.

[0006] To this end, the present invention proposes an upper limb muscle strength comprehensive training system, which can solve the problems of existing upper limb muscle strength training equipment in existing nursing homes, such as single function, many types of equipment required for upper limb comprehensive training, large space occupation and monotonous training process.

[0048] Figure 8 As shown, when the double-arm lifting and pressing movement mechanism 4 is in use, the lifting and pressing rotating arm 42 is in the solid line position in the figure; when the double-arm lifting and pressing movement mechanism 4 is not in use, the lifting and pressing rotating arm 42 can be manually rotated 180 degrees backward and positioned by the rotating arm positioner 44 and placed at the rear of the front vertical frame 51, that is, Figure 8 The dotted line position of the lifting and pressing rotating arm 42 is shown in the figure. This position does not affect the use of other sports mechanisms in the upper limb muscle strength comprehensive training system.

[0049] like Figure 11As shown, the double-arm push-pull movement mechanism 6 is used for the trainee to perform double-arm push-pull exercise training. The mechanism is a left-right symmetrical structure relative to the stand support unit 5. From the right side structure, the mechanism mainly includes: a push-pull handle 61, an adjustable rotating arm 62, a steering positioner 63, a swinging frame 64, a connecting plate 65, a hinged plate 66, and a third damper 67; wherein the push-pull handle 61 is fixedly sleeved on the front end of the adjustable rotating arm 62; the connecting plate 65 and the hinged plate 66 are respectively fixedly connected to the rear side and the front side of the middle part of the horizontal frame of the swinging frame 64, and each is symmetrically arranged in two left and right parts; the stand support unit 5 A fixed shaft sleeve 521 is fixedly mounted on the rear vertical frame 52 of the support unit 5; two connecting plates 65 are hingedly connected to the fixed shaft sleeve 521. The upper end of the sleeve-type third damper 67 is hingedly connected to the hinge plate 66, and its lower end is hingedly connected to the fixed hinge seat 531 on the upper longitudinal beam 53. The swinging rotating frame 64, the third damper 67, and the vertical support unit 5 form a rotating slider mechanism. During active push-pull training, the user grasps the push-pull handle 61 with both hands and pushes it up and down, driving the swinging rotating frame 64 to rotate about the axis of the fixed shaft sleeve 521, and simultaneously driving the third damper 67 to produce a telescopic damping motion. The bidirectional damping of the third damper during its extension and retraction can be adjusted according to the user's muscle strength level to meet the different damping requirements during personalized exercise training.

[0050] like Figure 12 As shown, the front end of the adjustable swivel arm 62 is fixedly sleeved with the push-pull handle 61, and the rear end is fixedly provided with a protruding support shaft, and the axial diameter of the support shaft is provided with two positioning holes spaced 180 degrees apart. The support shaft is inserted into the sleeve hole of the swinging rotating frame 64, and the two are rotationally matched and connected, and the adjustable swivel arm 62 can rotate around the sleeve hole of the swinging rotating frame 64; a steering positioner 63 is provided on the swinging rotating frame 64, and a threaded positioning hole is opened on the swinging rotating frame 64. The steering positioner 63 is screwed into the threaded positioning hole and then inserted into the positioning hole of the support shaft, thereby adjusting the upper and lower positions of the adjustable swivel arm 62. By unscrewing the steering positioner 63, the adjustable swivel arm 62 can be easily flipped 180 degrees around the sleeve center of the swinging rotating frame 64. After loosening the steering positioner 63, the adjustable swivel arm 62 is repositioned, thereby realizing the adjustment of the height of the adjustable swivel arm 62 to meet the trainee's double-arm push-pull exercise training in a sitting or standing position. Figure 12 As shown in the figure, the adjustable rotating arm 62 shown by the dotted line is the position when the trainee performs double-arm push-pull exercise training in a sitting position, and the adjustable rotating arm 62 shown by the solid line is the position when the trainee performs double-arm push-pull exercise training in a standing position. At the same time, in order to cooperate with training in different postures, the seat plate 22 of the seat system also requires corresponding use and adjustment operations in the folded state.

[0051] like Figure 13As shown, the display module 7 includes a display position adjustment mechanism and a display 71, and the display position adjustment mechanism is connected and fixed on an arm of the U-shaped seat 11 in the chassis support unit 1, and the display position adjustment mechanism includes a connecting seat 72, a supporting vertical pipe 73, a height positioner 74, an adjusting arm 75, a horizontal swing fine-tuner 76, and a vertical swing fine-tuner 77; wherein the connecting seat 72 is directly mounted and fixed on the U-shaped seat 11; the adjusting arm 75 includes a cross bar and a vertical rotating shaft fixedly arranged below the cross bar; the lower end of the supporting vertical pipe 73 is fixedly connected to the connecting seat 72, and its upper end is hinged to the vertical rotating shaft of the adjusting arm 75, and the vertical rotating shaft is inserted into the pipe mouth at the upper end of the supporting vertical pipe 73; the height positioner 74 (such as a handle bolt) is installed on the supporting vertical pipe 73; the horizontal swing fine-tuner 76 is hinged to the other end of the cross bar of the adjusting arm 75; one end of the vertical swing fine-tuner 77 is hinged to the horizontal swing fine-tuner 76, and the other end is fixed on the display 71.

[0052] like Figure 14 As shown, the lower portion of the horizontal swing fine-tuner 76 is a vertical hinged shaft structure, comprising a lower friction pad 762, a wear-resistant sleeve 763, and a hinged shaft body. The other end of the adjustment arm 75 has an axial hole. The lower portion of the hinged shaft body is a vertical shaft with a threaded hole at the bottom. The vertical shaft is inserted through the lower friction pad 762 and then into the wear-resistant sleeve 763. A locking bolt is inserted upward from the bottom of the axial hole into the threaded hole of the vertical shaft and tightened with a gasket, allowing the hinged shaft body to rotate left and right around the sleeve 763. A horizontal through-hole is provided at the rear of the hinged shaft body. The two hinged ends of the vertical fine-tuner 77 are mounted on either side of the horizontal through-hole. The hinged shaft is inserted through the opening at one hinged end and exits through the opening at the other hinged end, where it is locked with a nut. This allows the vertical fine-tuner 77 to rotate up and down around the hinged shaft. The other end of the vertical swing fine-tuner 77 is fixedly connected to the display 71. By operating the knob of the height positioner 74 to tighten or loosen the vertical shaft on the adjustment arm 75, the height and angle of the display 71 can be adjusted, and then the position of the display 71 can be adjusted; by manually operating the small-angle swing of the horizontal swing fine-tuner 76 and the vertical swing fine-tuner 77, the small-range adjustment of the screen angle in the display can be achieved.

[0053] Through the display position adjustment mechanism, comprehensive adjustment of the height, front-to-back distance and screen angle of the display 71 is achieved, which better meets the trainee's visual feedback muscle strength training needs.

[0054] The double-arm retraction and extension movement mechanism 3 further includes two sets of angle sensors, which are respectively located at the hinge positions of the left and right turning arms 32 and the chassis support unit 1. The angle sensors can transmit the angle parameters in the movement training to the display 71 in real time for visual feedback training and evaluation.

[0055] The double-arm lifting and pressing movement mechanism 4 further includes a set of angle sensors located at the connection between the rear rocker arm 43 and the fixed shaft seat 513. The angle sensors can transmit angle parameters to the display 71 in real time for visual feedback training and evaluation.

[0056] The double-arm push-pull motion mechanism 6 further includes a set of angle sensors located at the rotating shaft connecting the swinging rotating frame 64 and the fixed shaft sleeve 521. The angle sensors can transmit angle parameters to the display 71 in real time for visual feedback training and evaluation.

[0057] In the present invention, when the trainee is training in a sitting position, he or she can perform double-arm contraction and extension exercise training alone, or can perform double-arm lifting and pressing exercise training, or double-arm push-pull exercise training alone (the adjustable rotating arm 62 is adjusted to a low position at this time); when the trainee is training in a standing position, it is generally only suitable to perform double-arm push-pull exercise training (the adjustable rotating arm 62 is adjusted to a high position at this time).

[0058] In summary, the present invention has the following outstanding features:

[0059] 1. It can meet the needs of trainees to achieve three types of upper limb muscle strength training on one device, including double-arm extension and retraction movement mechanism, double-arm lifting and pressing movement mechanism, and double-arm pushing and pulling movement mechanism. It can comprehensively train the arm muscle groups, chest muscles and shoulder and back muscle groups, and can effectively meet the training needs of those with weak upper limb muscle strength.

[0060] 2. The seat system can be quickly folded or opened through manual operation, which can meet the needs of different trainees to choose to carry out corresponding upper limb muscle strength training in a sitting or standing position.

[0061] 3. The arm extension and retraction movement mechanism is equipped with an adjustable handle assembly. The trainee can choose to adjust the adjustable handle to the vertical or horizontal position according to the functional condition of his upper limbs to perform muscle strength training under the horizontal extension and retraction movement of the upper limbs or muscle strength training under the flexion and retraction movement of the upper limbs.

[0062] 4. The double-arm lifting and pressing exercise mechanism is used for upper limb muscle strength training in a sitting position. Under the set resistance of the second damper, the lifting and pressing handle is grasped by hand to perform lifting or pressing movement training of the lifting and pressing rotating arm. It is suitable for exercise training in a small range of the upper limbs. When not in use, the lifting and pressing rotating arm can be rotated and placed at the rear of the front vertical frame without affecting the use of other exercise mechanisms in the present invention.

[0063] 5. The adjustable rotating arm of the double-arm push-pull exercise mechanism has a height adjustment function, and in conjunction with the opening or folding of the seat system, the trainee can choose to perform double-arm push-pull exercise training in a sitting or standing position.

[0064] 6. Angle sensors are installed in the double-arm extension and retraction movement mechanism, double-arm lifting and pressing movement mechanism, and double-arm pushing and pulling movement mechanism, which can send the detected angle data to the display interface in real time, assisting trainees in carrying out visual feedback training system, making upper limb muscle strength training more targeted and entertaining, and significantly improving training enthusiasm.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
