Description

Technical Field

[0001] The present invention relates to a training device, and more specifically, to an upper limb multi-dimensional motion training device, belonging to the field of sports equipment. Background Art

[0002] Tai Chi Wheel, also called shoulder joint trainer, is mainly used to increase the mobility of shoulders, elbows, hips, knees, etc. Exercise method: stand facing any turntable of the Tai Chi Wheel, with legs apart in a horse stance, upper body naturally straightened, lower abdomen slightly contracted, hands flattened and spread out to press the convex surface of the turntable, and then turn in the same or opposite direction.

[0003] The general Tai Chi wheel trainers currently on the market have the following four obvious defects: ① The turntable has no adjustable speed and force, and there is a risk of failure if it is not operated properly. ② If the user has limb disabilities, there is a risk of spraining muscles or joints during exercise. ③ If the user's height and arm span do not match well, it will be difficult to control the turntable during operation. ④ There is only one action, the turntable rotates around the axis. Because of the small number of actions, the gameplay is monotonous, the training effect is limited, and it is unable to provide a variety of targeted training strategies.

[0004] There are not many technical directions related to the existing Tai Chi wheel training devices. Some focus on fun, such as the "A sound and body combined exercise device" with the existing patent document application number 201810436059.3, which "combines pedal-type fitness with music performance to increase the fun of exercise"; some enhance the effect of wheel rotation, such as the "Tai Chi pile Tai Chi force Tai Chi wheel type fitness device" with the existing patent document application number 201710885720.4, which "uses water resistance and magnetic resistance as resistance sources, and rotates the Tai Chi wheel with both hands alternately to achieve the purpose of exercise". There are not many technical improvement plans for the above four obvious defects of conventional Tai Chi wheels. Therefore, the research and development of such improved equipment can supplement and improve the market ecology of Tai Chi wheel related products, and has high social value and commercial value.

[0060] A preferred embodiment is as follows: Figure 2 As shown, the base frame 1 is provided with a support seat 1.1 and a column seat 1.2 connected to the upper end of the support seat 1.1, and the column seat 1.2 is provided with a locking nut 1.21 for connecting with the column 2;

[0061] The lifting platform 3 includes legs 3.1, a lifting base 3.2, and a shock-absorbing platform 3.3. The legs 3.1 are fixed on the platform seat 1.1 of the base frame 1.

[0065] According to the technical solution of this application, the specific operation instructions are as follows:

[0066] Operation mode 1: One-handed mode.

[0067] like Figure 2 , 15 As shown in Figures 1 and 17, the single handle 16 in the present application can also be inserted into the lock sleeve 7.1 and locked by the locking button 7.11, and there is no relative movement between the single handle 16 and the slide bar 7. As mentioned above, at this time, the single handle 16 will have a maximum of 4 degrees of freedom of multi-dimensional movement of up, down, left, right, front, and back movement and rotation around the slide bar axis without restriction. When the ball axis resistance knob 5.51 is rotated inwards and the friction between the ball table 5.3 and the ball axis 6 increases, the up, down, left, and right movement of the single handle 16 is in a resistance state. When the ball axis resistance knob 5.51 continues to be rotated inwards to lock the ball axis 6, the single handle 16 can only move forward and backward and rotate around the slide bar axis. When using, the user first adjusts the number of weight plates 16.2 on the single-handle, and then adjusts the shock-absorbing support platform 3.3 to a suitable height by adjusting the lifting base 3.2 and the locking knob 3.21, and can also adjust the position of the adjustable stopper 8 as needed. When the single-handle 16 is dropped to the non-exercise area for arm operation, the shock-absorbing rotary sleeve 9 contacts the shock-absorbing support platform 3.3, and the shock-absorbing rotary sleeve 9 can roll on the shock-absorbing support platform 3.3 with the left and right swings of the slide bar 7. The rolling range of the shock-absorbing rotary sleeve 9 is limited by the rotation range of the ball shaft 6 on the ball platform 5.3, so as to keep the user's use within a safe range. The single-handle 16 can be installed on the left slide bar 7, or on the right slide bar 7, or on both sides at the same time, so that one hand or both hands can be selected for simultaneous use.

[0068] Operation mode 2: Barbell mode.

[0069] The handlebar combination connecting rod 17 is used to combine and connect the single handlebars 16 on the left and right sides. Figure 6 , 15 -16, the handle combination connecting rod 17 is connected to the threads on the single handle frames 16.1 on the left and right sides. At this time, the user can use it with both hands in a barbell operating posture. Since the single handles 16 on both sides are in a locked relationship with the handle combination connecting rod 17, the single handles 16 on both sides can only move forward and backward and up and down. With the help of the lifting support platform 3 to limit the downward movement of the single handle 16, the control and resistance ball table 5 to damp the upward and downward movement of the single handle 16, and the adjustable anti-slip device 8 to prevent the sliding rod 7 from falling off in the rear position, the above measures can provide good protection for the barbell movement.

[0070] Operation mode three: Tai Chi wheel mode.

[0071] The Taiji wheel 13 is connected in series with the dual-axis resistance-adjusting universal joint 12, the bearing connector 11, the adjustable damping bearing seat 10, and the locking sleeve 7.1, such as Figure 3 , 11 As shown in 18-20, as mentioned above, due to the degrees of freedom of the connection between the ball shaft 6, the ball table 5.3 and the slide bar 7, when the user is using it, the upper limbs can move up and down, left and right, forward and backward, and rotate around the axis of the slide bar 7. In addition, the three axial degrees of rotational freedom brought about by the connection between the adjustable damping bearing seat 10 and the dual-axis adjustable resistance universal joint 12, the user's wrist holding the Tai Chi wheel 13 can also rotate up and down, left and right, forward and backward. As a result, the operating actions brought about, in addition to Fig.18 In addition to the conventional Tai Chi wheel movements shown in Fig.19 Change the position of the Tai Chi wheel as shown, and Fig. 20 The change in the orientation of the Tai Chi wheel 13 shown in the figure allows the user to exercise a greater number of joints and muscle groups, and compared with the traditional Tai Chi wheel, the operable movements are also closer to the actual movements of Tai Chi. In addition, since the ball table 5.3, the damping adjustment bearing seat 10 and the dual-axis resistance adjustment universal joint 12 of the device have the resistance adjustment function, the user can also perform resistance training of moving the arm up and down, left and right, and rotating the wrist up and down, left and right, front and back with one hand or two hands when operating the Tai Chi wheel. The above-mentioned damping effect and the safety design of the lifting platform 3, the low-position limiter 4, the adjustable anti-slip device 8 and other devices can provide users with good operational safety guarantees.

[0072] Operation mode 4: Tai Chi ball mode.

[0073] The Tai Chi ball 14 is connected in series with the bearing connector 11, the adjustable damping bearing seat 10, and the lock sleeve 7.1, such as Figure 4 , 12As shown in 21-22, as mentioned above, due to the degrees of freedom of the connection between the ball shaft 6 and the ball table 5.3 and the slide bar 7, when the user uses it, the upper limbs can move up and down, left and right, front and back, and rotate around the axis of the slide bar 7. In addition, the adjustable damping bearing seat 10 can also provide one degree of freedom of rotation around the axial direction of the bearing seat, and the user's wrist holding the Tai Chi wheel can also rotate up and down, left and right, front and back.

[0074] Specifically, Tai Chi ball 14 has two training modes: Fig.21 As shown, this is the low-position relaxed mode, which is suitable for users with weak physical strength or slight movement obstacles. First, adjust the lifting platform 3 to a suitable height. At this time, the shock-absorbing rotating sleeve 9 is in contact with the shock-absorbing platform 3.3, the ball shaft 6 is in contact with the collision block 8.3, and the resistor 10.22 on the adjustable damping bearing seat 10 is in a relaxed state. The weight of the Tai Chi ball 14 is borne by the lifting platform 3. When the user rotates the Tai Chi ball 14, relative rotational motion occurs between the adjustable damping bearing seat 10 and the slide bar 7, and there is no relative rotation between the slide bar 7 and the ball shaft 6. The user can also push the Tai Chi ball 14 to move left and right. At this time, the shock-absorbing rotating sleeve 9 rolls on the shock-absorbing platform 3.3 and rotates relative to the slide bar 7.

[0075] like Fig. 22 As shown, this is a resistance training mode, which is suitable for users who need to perform enhanced training. First, adjust the lifting platform 3 to a suitable height. At this time, the resistor 10.22 on the adjustable damping bearing seat 10 has been adjusted to a tightened state in advance. The user picks up the ball and moves it up and down, left and right, front and back, and rotates it around the slide bar 7. This action is similar to the experience of users holding an unconstrained ball for Tai Chi ball training. The difference is that the damping effect of this device and the safety design of the lifting platform 3, low-position limiter 4, adjustable anti-slip device 8 and other devices can provide users with good operational safety protection when the action fails, such as slipping, insufficient limb support, and joint stress. Of course, this device can also be used Fig.23 The installation method of the adjustable anti-slip device 8 shown restricts the forward and backward movement of the slide bar 7 to further improve the safety of the device.

[0076] Operation mode five: two-handed mode.

[0077] The double-handle 15 is connected in series with the dual-axis resistance-adjusting universal joint 12, the bearing connector 11, the adjustable damping bearing seat 10, and the locking sleeve 7.1, such as Figure 5 , 13-14, 23, at this time, two adjustable anti-slip devices 8 are installed on both sides of the ball shaft 6 on the slide bar 7, so that the collision block 8.3 of the adjustable anti-slip device 8 is in force contact with the ball shaft 6. As mentioned above, due to the freedom of connection between the ball shaft 6 and the ball table 5.3 and the slide bar 7, when using the handle 15, the user's upper body can move up and down, left and right and rotate around the axis of the slide bar 7 to a large extent. In addition, the three axial rotational degrees of freedom brought about by the connection between the adjustable damping bearing seat 10 and the dual-axis resistance regulating universal joint 12 result in that the upper limbs of the user holding the handle 15 with both hands can also perform small up and down, left and right, front and back rotational movements.

[0078] Specifically, the operation modes of the two-hand handle 15 are as follows:

[0079] Mode 1, fixed-point push-pull. First, adjust the adjustable stoppers 8 on both sides of the ball table to a suitable distance, so that the slide bar 7 can match the user's physical strength and exercise needs when it is elastically displaced forward and backward. Tighten and lock all the resistance adjustment devices including the ball table 5.3, the adjustable damping bearing seat 10, and the dual-axis resistance adjustment universal joint 12. Move the connecting frame 15.1 in the double handle 15 forward and backward along the slide groove 15.221 to a suitable position, and then lock the locking screw 15.11. The user can now operate the two hands to perform reciprocating push-pull training movements in the set direction and angle.

[0080] Mode 2, near-end rotation push and pull. Based on mode 1, loosen the damper 10.22 of the adjustable damping bearing seat 10 and the resistance adjusting nut on the dual-axis resistance adjusting universal joint 12 to a suitable degree according to the required resistance. When the user pushes and pulls the double handle 15, the double handle 15 can rotate around the axial direction of the adjustable damping bearing seat 10. At the same time, the double handle 15 can be operated to rotate along the axial direction of the front and rear resistance adjusting screw group 12.4 and the left and right resistance adjusting screw group 12.5 according to the use needs.

[0081] Mode 3: Push and pull with large movements. On the basis of Mode 2, loosen the ball axis resistance knob 5.51 on the table to a suitable degree according to the required resistance. When the user operates, the movement range of the limbs can be increased based on the movement in Mode 2.

[0082] Operation mode six: mixed mode.

[0083] Different exercise combinations are achieved by connecting the Tai Chi wheel 13, the Tai Chi ball 14, the single-hand handle 16, and the double-hand handle 15 to the lock sleeves 7.1 of the slide bars 7 on the left and right sides, so as to match different exercise needs, such as Fig.24As shown, the adjustable damping bearing seat 10, the bearing connector 11, and the Tai Chi ball 14 are connected in series behind the locking sleeve 7.1 on one side, and the adjustable damping bearing seat 10, the bearing connector 11, the dual-axis resistance-adjustable universal joint 12, and the Tai Chi wheel 13 are connected in series behind the locking sleeve 7.1 on the other side, thereby realizing a training layout form, so that people with different training needs can use the trainer at the same time.

[0084] Finally, it should be noted that the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by ordinary technicians in this field should be considered as the protection scope of the present invention.
