Description

Technical Field

[0001] The utility model belongs to the technical field of sports equipment, and particularly relates to an isometric exercise training device. Background Art

[0002] Isometric exercise, also known as static exercise, is a type of exercise in which the muscles contract but the muscle fibers do not shorten. This type of exercise increases the muscle tension without changing the muscle length. The characteristic of isometric exercise is that the muscle length remains unchanged and no joint movement occurs. Common isometric exercises include wall sits, planks, hip bridges, horse stances, and tiptoe raises (calf raises), etc. Isometric exercise can enhance muscle strength and endurance, improve body stability, and also improve cardiopulmonary function, reduce the risk of diseases such as heart disease and stroke, and help increase bone density and enhance joint stability. Currently, the training devices for isometric exercise on the market can only adapt to users of a certain body type or can only be used for training in a fixed position, unable to adjust to a suitable position for oneself, or can only be used for isometric exercise in a sitting or standing position, so the applicability is poor. And the existing training devices cannot obtain immediate and subsequent feedback to understand one's own performance and subsequent practice, or cannot be used in conjunction with free weights, elastic bands, bandages, springs, pulleys or similar resistance devices.

The support structure 8 includes three vertical members: the first vertical members 8a, 8c on both sides, and the second vertical member 14 in the middle. The first vertical members 8a, 8c are fixedly connected to a plurality of horizontally arranged cross beams 8b at the same time to maintain the stability of the support structure 8. The second vertical member 14 can be inserted into the corresponding slots on the bottom plate 10 and abutted against a plurality of cross beams 8b (see Figure 2 ), to achieve fixation.

[0028] The back plate 15 can move up and down along the second vertical member 14 in the support structure 8 independently of the seat plate 6. When in use, for example, when practicing wall sits, the user stands with both feet on the bottom plate 10, the back is against the back plate 15, and the thighs and calves stand at an angle of about 90°, realizing isometric muscle exercise.

[0029] The seat plate 6 is connected to the support structure 8 through a rotating shaft and can rotate relative to the rotating shaft. For example, it can be rotated to be parallel to the back plate 15 and then positioned at this position; or rotated to be perpendicular to the back plate 15, or 90° ± 10°, and the specific angle depends on the user's needs, and then positioned at this position, so as to meet the isometric exercise in sitting and standing postures.

[0030] See Figure 1A and 1B , upper limb training components are pivotally provided at the tops of the two first vertical members 8a, 8b of the support structure 8. The upper limb training components are respectively located on both sides of the back plate 15. The upper limb training component includes a shoulder 1; an upper arm part 2; a lower arm part 3 and a handle 5. Among them, the shoulder 1 of the upper limb training component is vertically arranged, and its bottom is pivotally connected to the first vertical members 8a, 8b through a pivot member, Figure 1A in which the pivot member is a ratchet. The whole upper limb training component can rotate around the longitudinal axis. When rotated to the required angle, the ratchet is fixed to adapt to the exercises of users with different heights, different body types and different training methods. The upper arm part 2 and the lower arm part 3 of the upper limb training component are arranged with reference to the contour of the human upper limb. Among them, the upper arm part 2 is pivotally connected to the shoulder 1 through a ratchet and can rotate up and down, that is, the rotation direction of the upper arm part 2 is perpendicular to the rotation direction of the shoulder 1. The lower end of the upper arm part 2 is pivotally connected to the lower arm part 3, imitating the human elbow. The lower arm part 3 can rotate up and down. A pressure and / or time reading display 4 and a handle 5 are provided at the end of the lower arm part 3. The number of handles 5 is one or more, Figure 1AThere are three handles provided therein, including a horizontal handle 5 and two vertical handles 5 perpendicular to the base plate 10 (above and below the lower arm portion 3 respectively and extending in opposite directions), which is beneficial to exercising different muscle / joint groups through different gripping angles. In other embodiments, the number of handles can also be two. Through this setting, the distance and relative angle between the handle and the shoulder can be adjusted arbitrarily to adapt to the exercise of users with different arm spans of different angles and lengths.

[0031] Preferably, pressure sensors are provided inside the horizontal handle 5 and the vertical handle 5, which can measure the exercise time and the applied pressure value of the user. The measured values can be displayed and recorded on the display 4 provided at the end of the lower arm portion 3 for the user to view at any time. In other embodiments, the pressure sensor can be wirelessly connected to a smart terminal, such as a mobile phone, iPad, tablet computer, etc., and the exercise time and pressure value are displayed on the smart terminal.

[0032] In one embodiment, as Figure 4 shown, an arm release assembly 7 is provided near the handle 5. When this assembly is pulled, it can release the upper limb training assembly (the lower arm portion 3 or the lower arm portion 3 together with the upper arm portion 2) from the locked state to the relaxed state, so that it can freely move to any position desired by the user.

[0033] As Figure 3 shown, the isometric exercise training device further includes a seat plate angle adjuster 12 and a seat plate height adjuster 11. The seat plate angle adjuster 12 can adjust the seat plate 6 from the position of 0° parallel to the back plate 15 to the position of 90° with the back plate 15. If the user needs, it can be further rotated 100° upward towards the back plate 15.

[0034] As Figure 1A shown, the second vertical member 14 is a strip-shaped structure with a square cross-section. As Figure 3 shown, a plurality of positioning teeth 11a are vertically provided on one side of the second vertical member 14. A slider is slidably connected to the second vertical member 14. The seat plate 6 is connected to the slider. The seat plate height adjuster 11 includes a rotating rod rotatably provided on the slider and a clamping rod (made of steel member) connected to the free end of the rotating rod. The clamping rod can be clamped into any one of the positioning teeth 11a, thereby allowing the seat plate and the back plate to freely move up and down to the most suitable seating position for the user.

[0035] The seat board height adjuster 11 further includes a first rotating handle 5 in an L shape that is vertically connected to the rotating rod. Pulling the first rotating handle 5 drives the rotation of the rotating rod, thereby driving the clamping rod away from the positioning teeth 11a. At this time, the height of the seat board 6 can be adjusted up and down. After adjusting to the target position, perform the reverse operation as described above to make the clamping rod engage with the corresponding positioning teeth 11a to fix the height of the seat board 6.

[0036] A connecting body is provided between the seat board 6 and the slider. The connecting body is hinged to the slider.

As Figure 6 shown, a control / locking assembly 18 is also provided on the ratchet 9. The control / locking assembly 18 further includes a support frame 24. A connecting plate is provided in the support frame 224 and there are stop pins 20, 21 that are resilient and abut against the ratchet columns. This resilience is achieved through a spring. Figure 6 shows that 3 stop pins are provided. The lengths of the two sides are greater than that of the middle one, and the ends of the stop pins on both sides extend outside the support frame and are fixed with end caps 23a. Specifically, as Figure 5 and 6 shown, a rotating shaft is fixedly provided inside the shoulder 1 and is fixedly connected to the distal disc 9a. Ratchet columns 9b are fixedly provided on the distal disc 9a; the top of the upper arm is fixedly connected to the proximal disc 9a. When adjusting the angle, pull up the end cap 23a, the stop pins leave the gaps between adjacent ratchet columns, and the upper arm 2 rotates around the rotating shaft. When turning to the required position, loosen the end cap 23a, and the stop pins are inserted into the gaps between adjacent ratchet columns, and the ratchet is locked. After setting a position suitable for oneself, the user can start the isometric training of the upper limb.

[0040] As Figure 1A and Figure 7 shown, the equal-length exercise training device further includes a lower limb training component, which is slidably connected to a groove 10b formed in the bottom plate 10 through a slide rail 34 on a lower strip 33, so that it can move in the front-rear direction of the trainer to adapt to trainers with different leg lengths. A positioning screw 32 is threadedly connected to the end of the lower strip 33 at the bottom of the lower limb training component. The positioning screw 32 passes through the strip and abuts against the bottom plate 10 and extends into the corresponding positioning hole, so that the position of the lower limb training component can be fixed at any position along the groove. A knob or other brake is provided at the top of the positioning screw 32, and the position of the lower limb training component can be firmly fixed on the bottom plate by turning the knob or other brake.

[0041] As Figure 7 shown, the lower limb training component is also provided with a pair of positioning rods 25. The positioning rods 25 are horizontally arranged, and their outer walls are provided with flexible cushioning materials such as foam, rubber or leather, which are in contact with the ankles and are used for leg raising or leg curling exercises.

[0042] In one embodiment, a pressure sensor is provided in the positioning rod 25, which can generate signals related to and / or reflected by the pressure exerted by the leg / foot (for example, upward movement), and can be transmitted to a remote or local device, or displayed on a display screen 26 provided near the positioning rod 25 to display improvements or specific values related to the user's exercise, facilitating the user to view the screen and enabling the collation of these measured data values to provide suggestions for continuous improvement for the user.

[0043] The lower limb training component includes a plurality of strip members hinged to each other.
