Description

TECHNICAL FIELD

[0001] The present application relates to a training device, more particularly to a multi-dimensional upper limb exercise device, and belongs to the field of exercise equipment. BACKGROUND

[0002] Taiji wheel, also known as shoulder joint training device, mainly functions to increase the activity of shoulder, elbow, hip, knee and other parts. The exercise method is to stand in front of any one rotating disc of the Taiji wheel, with legs apart in horse stance, body naturally upright, abdomen slightly contracted, hands flat and pressed tightly on the convex platform of the rotating disc, and then rotate in the same or opposite direction.

[0003] The currently marketed general Taiji wheel training device has the following four obvious defects: ① the rotating disc has no speed and force adjustment and limiting, and there is a risk of failure when operated improperly. ② If the user's limbs have obstacles, there is a risk of muscle or joint sprain during exercise. ③ If the user's height and arm span matching degree is not high, there is a problem of difficulty in controlling the rotating disc during operation. ④ There is only one rotating disc rotating around the axis, and because of the few actions, the play is monotonous, the exercise effect is limited, and it cannot provide multiple targeted training strategies.

[0004] There are not many technical directions for the existing Taiji wheel training device. Some pay attention to fun, such as the existing patent document with application number 201810436059.3 "sound-body combination exercise device", which combines foot-pedal exercise with music performance to increase the fun of exercise. Some enhance the rotating effect of the disc, such as the existing patent document with application number 201710885720.4 "Taiji posture Taiji force Taiji disc type fitness equipment", which uses water resistance and magnetic resistance as resistance source to achieve the purpose of exercise by rotating Taiji disc alternately with both hands. For the above four obvious defects of the conventional Taiji wheel, there are not many technical improvement schemes at present, so the development of such improved equipment can supplement and perfect the market ecology of Taiji wheel related products, and has high social value and commercial value.

[0047] The following will refer to the appendices in the embodiments of the present invention. Figures 1-24 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0048] In the description of the invention, it should be noted that the terms "upper", "lower", "inner", "outer", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0049] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an indirect connection through an intermediate medium, but the connections at various points do not affect the multi-position folding of this application. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] The inventiveness of this invention lies in its use of ball joints and universal joint mechanisms in conjunction with sliding rods to expand the degrees of freedom of training devices such as Tai Chi wheels. This allows users to employ a wider range of movements and postures. Furthermore, resistance adjustment mechanisms have been added to the ball table and the dual-axis universal joint to meet the requirements of resistance training or deceleration safety. In addition, multiple failure safety designs have been added, including a lifting platform, a low-position limiter, an adjustable anti-detachment device, and a shock-absorbing rotating sleeve, thus supplementing and improving the market ecosystem of Tai Chi wheel-related products.

[0051] Technical principle: The ball shaft 6 rotates within the constraint of the ball table 5.3, and the slide rod 7 slides back and forth in the through hole 6.1 of the ball shaft 6. Thus, the end locking sleeve 7.1 of the slide rod 7 realizes a multi-dimensional motion with four degrees of freedom, including up, down, left, right, forward and backward movement and rotation around the axis of the slide rod 7. At the same time, the addition of a rotating shaft 10.1 and a universal joint 12 to the end locking sleeve 7.1 of the slide rod realizes a multi-dimensional motion with three degrees of freedom, including up, down, left, right, forward and backward rotation of the user's gripping end (e.g., a Tai Chi wheel).

[0052] This embodiment discloses an upper limb multidimensional exercise trainer, including a base frame 1 and a column 2 and a lifting platform 3 connected to the base frame 1.

[0065] According to the technical scheme of the present application, the following specific operation is described:

[0066] Operation mode one: single handle mode.

[0067] As shown in Figure 2 , 15 , 17, the single handle 16 in the present application can also be inserted into the lock sleeve 7.1 and locked by the locking knob 7.11, and the single handle 16 and the slide rod 7 have no relative movement. As described above, at this time, the single handle 16 will have at most 4 degrees of freedom of multi-dimensional movement of up-down, left-right, forward-backward movement and self-rotation around the slide rod axis in an unlimited case. When the ball shaft resistance adjusting knob 5.51 is rotated inward, the friction between the ball table 5.3 and the ball shaft 6 increases, and the up-down, left-right movement of the single handle 16 is in a resistance state. When the ball shaft resistance adjusting knob 5.51 continues to rotate inward to make the ball shaft 6 in a locked state, the single handle 16 will only be able to move forward and backward and rotate around the slide rod axis. When the user uses it, first adjust the number of counterweight pieces 16.2 on the single handle, then adjust the shock absorbing supporting column 3.3 to a suitable height by adjusting the lifting base 3.2 and the locking knob 3.21, and also adjust the position of the adjustable stopper 8 as needed.

The shock absorbing rotating sleeve 9 can roll on the shock absorbing supporting column 3.3 with the left-right swinging of the slide rod 7. The rolling range of the shock absorbing rotating sleeve 9 is limited by the rotating range of the ball shaft 6 in the ball table 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 rod 7 or the right slide rod 7, or both sides at the same time, so as to choose single hand or double hands to use at the same time.

[0068] Operation mode two: barbell mode.

[0069] The left and right single handlebars 16 are connected in combination by the handlebar combination link 17, as shown in Figure 6 , 15 The handlebar combination link 17 is connected to the threads on the left and right single handlebar frames 16.1, as shown in 16, at this time, the user can use both hands in a barbell operation posture, since the left and right single handlebars 16 are in a locked relationship with the handlebar combination link 17, the left and right single handlebars 16 will only be able to move forward and backward and up and down, cooperating with the single handlebar 16 downward displacement limiting, control and resistance ball table 5 up and down movement damping, adjustable anti-dropping device 8 rear position anti-dropping of slide rod 7, the above measures can provide good protection for barbell movement.

[0070] Operation mode three: Taiji wheel mode.

[0071] The Taiji wheel 13 is connected in series with the double-axis resistance adjusting universal joint 12, bearing connector 11, adjustable damping bearing seat 10, and lock sleeve 7.1, as shown in Figure 3 , 11 , 18-20, as described above, due to the freedom of connection between the ball shaft 6 and the ball table 5.3 and the slide rod 7, the user can move the upper limbs up, down, left, right, forward and backward, and rotate around the axis of the slide rod 7, in addition, the user's wrist holding the Taiji wheel 13 can also move up, down, left, right, forward and backward, due to the operation action, in addition to the conventional Taiji wheel action shown in Figure 18 , the user can also change the position of the Taiji wheel as shown in Figure 19 , and change the orientation of the Taiji wheel 13 as shown in Figure 20 , so that the user can exercise a larger number of joints and muscle groups, and the operation action is closer to the actual action of Taijiquan compared to the traditional Taiji wheel. In addition, since the ball table 5.3, the adjustable damping bearing seat 10 and the double-axis resistance adjusting universal joint 12 of the device have a resistance adjusting function, the user can also operate with one hand or both hands to move the arms up, down, left, right and the wrist up, down, left, right, forward and backward. The damping effect and the safety design of the devices such as the lifting platform 3, the low position limiter 4, and the adjustable anti-dropping device 8 can provide good operation safety guarantee for the user.

[0072] Operation mode four: Taiji ball mode.

[0073] The Taiji ball 14 is connected in series with the bearing connector 11, adjustable damping bearing seat 10, and lock sleeve 7.1, as shown in Figure 4 , 12, 21-22, as described above, due to the freedom of connection between the ball shaft 6 and the ball table 5.3 and the slide bar 7, the user can move up and down, left and right, forward and backward, and rotate around the axis of the slide bar 7 during use. In addition, the adjustable damping bearing seat 10 can provide one degree of freedom of rotation around the bearing seat axis, and the user's wrist holding the Taiji wheel can also perform rotational movement up, down, left, right, forward and backward.

[0074] Specifically, the Taiji ball 14 has two training modes: as shown in Figure 21 , it is a low position and easy mode, suitable for users with weak physical strength or slight movement obstacles. First, adjust the lifting support 3 to the appropriate height. At this time, the shock absorbing sleeve 9 is in contact with the shock absorbing support 3.3, the ball shaft 6 is in contact with the impact block 8.3, and the damper adjuster 10.22 on the adjustable damping bearing seat 10 is in a relaxed state. The weight of the Taiji ball 14 is borne by the lifting support 3. When the user rotates the Taiji ball 14, the relative rotational movement 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 move the Taiji ball 14 left and right. At this time, the shock absorbing sleeve 9 rolls on the shock absorbing support 3.3 and rotates relative to the slide bar 7.

[0075] As shown in Figure 22 , it is a resistance training mode, suitable for users who need to enhance training. First, adjust the lifting support 3 to the appropriate height. At this time, the damper adjuster 10.22 on the adjustable damping bearing seat 10 has been adjusted to a tight state in advance. The user holds the ball and moves up, down, left, right, forward and backward, and rotates around the axis of the slide bar 7. This action is similar to the user's experience of Taiji ball training with an unconstrained ball. The difference is that the damping action of the device and the safety design of the lifting support 3, the low position limiter 4, the adjustable anti-falling device 8, etc. can provide good operation safety protection for the user when the action fails, such as slipping hands, insufficient limb support, and joint stress. Of course, the device can also use the installation method of the adjustable anti-falling device 8 shown in Figure 23 to constrain the forward and backward movement of the slide bar 7, thereby further improving the safety of the device.

[0076] Operation mode five: double handle mode.

[0077] The double handle 15 is connected in series with the double shaft damper adjusting universal joint 12, the bearing connector 11, the adjustable damping bearing seat 10, and the lock sleeve 7.1, as shown in Figure 5 , 13As shown in FIGS. 14 and 23, at this time, two adjustable stoppers 8 are installed on both sides of the ball shaft 6 on the slide rod 7, and the impact block 8.3 of the adjustable stopper 8 is in force contact with the ball shaft 6. As described above, due to the freedom degree of the connection between the ball shaft 6, the ball table 5.3 and the slide rod 7, the user can move the upper body in a large amplitude up-down, left-right and around the axis of the slide rod 7 when using the double handles 15. In addition, the three axial rotation freedom degrees brought by the connection of the adjustable damping bearing seat 10 and the double-axis adjustable damping universal joint 12 result in that the upper limbs holding the double handles 15 can also perform small amplitude rotation movements in up-down, left-right, forward and backward directions.

[0078] Specifically, the operation actions of the double handles 15 have the following modes:

[0079] Mode 1, fixed-point push-pull. First, the adjustable stoppers 8 on both sides of the ball table are adjusted to an appropriate distance, so that the slide rod 7 can match the user's physical strength and movement needs when being elastically forced in the front-back direction. The adjustable damping device including the ball table 5.3, the adjustable damping bearing seat 10 and the double-axis adjustable damping universal joint 12 is all adjusted tightly and locked. After the connecting frame 15.1 of the double handles 15 is moved to the appropriate position along the sliding groove 15.221, the locking screw 15.11 is locked. At this time, the user can operate the double handles to do reciprocating push-pull training actions in the set direction and angle.

[0080] Mode 2, near-end rotary push-pull. On the basis of mode 1, the damper 10.22 of the adjustable damping bearing seat 10 and the adjustable resistance nut on the double-axis adjustable damping universal joint 12 are loosened to an appropriate degree according to the required resistance. When the user pushes and pulls the double handles 15, the double handles 15 can rotate around the adjustable damping bearing seat 10, and can also be operated to rotate in two axes along the front-back adjustable resistance screw set 12.4 and the left-right adjustable resistance screw set 12.5 according to the use needs.

[0081] Mode 3, large amplitude push-pull. On the basis of mode 2, the ball shaft adjustable resistance button 5.51 on the ball table is loosened to an appropriate degree according to the required resistance. On the basis of the action in mode 2, the user can also increase the amplitude of the limb movement up-down, left-right when operating.

[0082] Operation mode six: mixed mode.

[0083] The combination of the Tai Chi wheel 13, the Tai Chi ball 14, the single handle 16 and the double handles 15 connected to the lock sleeve 7.1 of the left and right slide rods 7 is adopted to realize different exercise combinations and match different exercise needs, such as Figure 24As shown, after the lock sleeve 7.1 on one side, the adjustable damping bearing seat 10, the bearing connector 11, the Taiji ball 14 are connected in series, and after the lock sleeve 7.1 on the other side, the adjustable damping bearing seat 10, the bearing connector 11, the double-shaft adjustable damping universal joint 12, the Taiji wheel 13 are connected in series, so that a training layout form is realized, and people with different training needs can use the training device at the same time.

[0084] Finally, it should be noted that the present application is not limited to the above embodiments, but can have many variations. All variations that can be directly derived or inferred from the disclosure of the present application by those of ordinary skill in the art should be considered within the scope of the present application.
