Description of the Invention: [Technical Field] The present invention relates to a type of HfT & / easy to wear and to reduce the load of the lower limbs when the movement of the lower limbs is carried out. [Prior Art] Conventional The lower limb assisted training is shocked and divided into external forces. The power source provides the driving force to the device ==,,:, or the passive component (such as the elastic crystal) = to the training effect, it is easier for the lower limbs In the case of the lower limb training device, the driving force element θ1 or the sensor is used to provide an auxiliary force to reduce the load generated by the user's lower limb weight 1. Taking U.S. Patent No. 7,278,979 and No. 75,599,9 as an example, the driving element such as a motor is disposed at the hip joint and the knee joint. When the user wants to move the lower limb portion, the motor can directly provide the corresponding joint. The assisting force 'is convenient to assist in performing the flexion or stretching of the corresponding joints to improve the effect during training. Another example is the US Patent No. 7549969, which uses a motor as a power source, and the combination of the rope and the pulley provided by the hip joint, the knee joint and the ankle joint can also achieve the corresponding joint movement effect. However, due to the arrangement of the driving components, the foregoing devices require the power supply to be activated when the device is used, which increases the energy consumption, and some devices may be too bulky and not portable, so that these devices can only be placed in the device. It is inconvenient for users to provide training at fixed locations such as hospitals. 201226010 Taking U.S. Patent No. 7,286,766 as an example, the device adopts a linear actuator disposed on the thigh portion and the lower leg portion, and the linear actuator can provide an auxiliary force to offset the weight of the lower limb, so that the user does not need to pass the joint during exercise. Produce extra strength to achieve the effect of lower limb movement. However, in addition to the aforementioned energy consumption problems, such devices are complicated in structural design, which often increases the instability of the device itself, and thus the probability of damage increases.

In the same manner as the design of the first embodiment, the present invention <lower limb muscle strengthening, entering a group to form a set of independent and asynchronous motion system, that is, the first rod group 20 which is formed by interlocking the rods and being twisted Through the structural interlocking of the first elastic member 40 and the third elastic member 6〇, the hip joint motion system capable of reducing the hip joint load can be formed corresponding to the flexion or extension of the hip joint; and the combination of the interlocking rod members The two-bar assembly 30 is coupled to the knot 2 of the second elastic member 50 and the fourth elastic member 7 to correspond to the flexion or extension of the knee joint, thereby forming a knee joint motion system capable of reducing the knee joint load.卜晴 Referring to Fig. 2 is a schematic view showing a second example of the lower limb muscle strengthening device la of the present invention. As shown in FIG. 2, in the present embodiment, the first fixing member 1A of the lower limb muscle strengthening device 1a of the present invention includes a guiding member u, and the first member group 20a is movably coupled to the guiding member. u, the first rod group 2〇a can be slid relative to the guiding member 11; likewise, the second rod group 3〇a can also be movably coupled to the guiding member u′ to make the second rod group 3〇 a is slidable relative to the guide n. 11 201226010 In this embodiment, the first rod set 20a and the second rod set 30a may each be a combination of a separate rod and a slider, and the slider is coupled to the guide U to be opposite to the guide. 11 is moved in a linear direction, and the rod system is pivotally connected to the slider to rotate relative to the slider; the two ends of the first elastic member 40a are respectively pivotally connected to the rod and the slider of the first rod group 20 a to form a first a pivoting point 4 〇丨a and a second pivoting point 402a, and the second pivoting point 402a is different from the pivotal point of the rod and the slider (in the present embodiment, the position of the second pivoting point 402a) The second elastic member 50a is also designed in the same manner as the first elastic member 40a, and the two ends of the second elastic member 5〇a are respectively pivotally connected to the first elastic member 40a. The rod body of the two-bar assembly 30a and the slider form a third pivot joint 5〇la and a fourth pivot joint φ point 502a′, and the fourth pivot joint 502a is different from the pivot joint of the rod body and the slider ( In this embodiment, the position of the fourth pivot point 502a is higher than the position of the pivot point of the rod and the slider). As shown in FIG. 2, when the thigh portion of the user is raised, the first rod group 2〇a pivotally connected to the second fixing member 80 is driven, so that not only the cups of the first rod group 20a are opposed to each other. The slider is rotated while causing the slider to translate into position relative to the first fixture 10a along the guide 11. During the process of raising the leg, as the position of the rod of the first rod set 2〇a is changed relative to the position of the slider, the first elastic member 4〇a will change its own elongation to generate an auxiliary force. It counteracts the effect of gravity on the movement of the thigh, and reduces the load on the joints of the lower limbs. It is convenient for the user to lift the thigh. Similarly, when the lower leg portion of the user is raised, the second rod group 30a pivotally connected to the third fixing member 90 is driven, so that not only the rod of the second rod group is rotated relative to the slider, but also The slider is translated along the guide 12 201226010 member 11 relative to the first fixture 10 in position. During the lifting of the calf, as the position of the rod of the second rod set 30a changes relative to the slider, the second elastic member 50a changes its own elongation to generate an assisting force to offset the gravity against the original calf. The effect of exercise reduces the load on the knee joint caused by the weight of the calf. According to the design of the second embodiment, the lower limb muscle strengthening device 1a of the present invention also forms two independent asynchronous motion systems, that is, the first member set 20a cooperates with the structure of the first elastic member 4〇a. Corresponding to the flexion or extension of the hip joint, the hip joint movement system capable of reducing the hip joint load can be formed, and the second joint member 3〇a cooperates with the structure of the second elastic member 5〇a to correspond to the knee joint. Flexing or stretching to form a knee joint motion system that reduces knee load. In the present invention, the design of each sliding component allows the user to change the position of the hip joint even when the waist or the pelvis is rotated or tilted during the movement, and the corresponding displacement can be generated by the sliding members without User motion causes obstacles to overcome the problem of incompatibility. Referring to Figure 3, there is shown a schematic view of a third embodiment of the lower limb muscle strengthening device of the present invention.

Wherein the first guiding member is substantially parallel to the second guiding member 112 such that the slider of the first member group 2〇b and the slider of the second member group 3 0 b move substantially parallel to each other The situation. Thereby, the possibility that the first rod group 2b and the second rod group 30b interfere with each other when moving is reduced to maintain the stability of use of the lower limb muscle strengthening device lb of the present invention. Further, in the present embodiment, the first member set 2B further includes a first length adjusting mechanism 27 for adjusting the overall length of the first member set 2〇b; the second set 30b further includes a second The length adjusting mechanism 37 is configured to adjust the overall length of the second rod set 30b. Each of the length adjusting mechanisms 27, 37 can be replaced by a telescopically adjustable rod or other structure having a similar function. By the arrangement of the length adjusting mechanisms 27, 37, the lower limb muscle strengthening device of the present invention can provide the user with the function of adjusting the lengths of the first rod group 2b and the second rod group 3〇b. The second fixing member and the third fixing member 90 are determined to be more suitable positions according to the needs of the user. In addition, in order to facilitate the first elastic member 4〇b and the second elastic member 5% to adjust the amount of elongation, in the embodiment, the first member set 2〇b further includes a first elastic adjustment mechanism 28, and the second rod The component set 3〇b further includes a second elastic force adjusting mechanism 38 for respectively connecting the first elastic member 4〇b and the second elastic member for adjustment. The first elastic adjusting mechanism 28 can change the position of the first pivoting point 401b or adjust the tightness of the first elastic member 4b to change the elongation of the first elastic member 40b; the second elastic adjusting mechanism 38 can borrow The amount of elongation of the second elastic member 5Gb is changed by adjusting the position of the third pivot point 501b or adjusting the tightness of the second elastic member 5b.
