Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically relating to a crawling fitness device. Background Technology

[0002] With the fast pace of modern life, people are paying more and more attention to health issues. Among the many fitness methods, crawling exercise has gradually gained attention. Crawling exercise is a way of exercising that imitates the crawling movements of animals. It has many benefits for human health, especially for the lumbar spine. It can not only effectively relieve lumbar spine pressure but also improve spinal flexibility and has a significant effect on the prevention and treatment of lumbar spine diseases. However, traditional crawling exercise has certain limitations, such as being limited by space and not obvious exercise effects.

[0003] To address the aforementioned issues, crawling equipment has emerged. Currently, most existing crawling exercise equipment requires users to exert force themselves. For example, Chinese utility model patent CN201921379942X discloses a crawling exercise device, which includes a main support frame with a torso balance plate fixed to it, guide rail supports on both sides of the main support frame, forearm support devices and lower leg support devices respectively mounted on the two guide rail supports. Each of the two guide rail supports has two axially oriented grooves on its sidewalls, located at opposite ends. The forearm support device and lower leg support device can slide axially within the two grooves of the guide rail support frame. During exercise, the user needs to place their hands and feet on the corresponding support devices to exert force independently. While this solves the problem of space limitations, the exercise intensity is high, often leading to fatigue before achieving the desired effect of strengthening the lumbar spine, and the exercise targets only a limited range of body parts.

[0004] Therefore, there is a need for a crawling fitness device that can effectively reduce fatigue and provide a variety of exercise targets. Utility Model Content

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] like Figure 1 and Figure 2 As shown, this utility model provides a crawling fitness device, including a box 1, a cover plate 2, a support 4, a head support device, two hand support devices 12, two foot support devices 13, a control mechanism, and a drive mechanism. The box 1 has an opening at its upper end, preferably located on one side of the top of the box 1. The cover plate 2 is detachably mounted on the opening of the box 1 using several bolts arranged circumferentially thereon. One end of the support 4 is located inside the front of the box 1, and the other end extends through the opening of the box 1 to the outside of the box 1 and is equipped with the head support device. The two hand support devices 12 and two foot support devices 13 are symmetrically arranged on the left and right sides of the box 1, extending through the side walls. Channels are formed in the side walls of the box 1 to accommodate the movement trajectories of the two hand support devices 12 and two foot support devices 13. The two hand support devices 12 are located at the front of the two foot support devices. Between the head support device and the head support device, the drive mechanism is set inside the box 1 and, under the control of the control mechanism 5, drives the head support device to reciprocate along the width direction of the box 1 on the bracket 4. At the same time, it also drives the two hand support devices 12 and the two foot support devices 13 to reciprocate along the length direction of the box 1. The movement directions between the two hand support devices 12 and between the two hand support devices 12 and the foot support device 13 on the same side are always opposite. That is, the movement directions between the two hand support devices 12, between the two foot support devices 13, and between a hand support device 12 and a foot support device 13 on the same side are opposite, thus forming a crawling mode that imitates animal walking in accordance with the bionic principle.

[0030] The control mechanism 5 uses a forward and reverse motor connected to a frequency converter. The switch controlling the frequency converter is located on the housing. The forward and reverse rotation of the motor is achieved by controlling the frequency converter, thereby enabling the drive mechanism to drive the reciprocating motion of the head support device, hand support device 12, and foot support device 13.

[0031] In use, the user places their chin on the head support device, and their hands and feet on the hand support device 12 and foot support device 13 respectively. After activating the control mechanism 5, the head support device, hand support device 12 and foot support device 13 work together under the action of the drive mechanism to allow the user to exercise their lumbar and cervical spine in a passive crawling motion. The exercise is effective and low-intensity, which can effectively reduce the user's fatigue. The lumbar and cervical spine can be exercised at the same time, realizing the diversity of exercise areas, improving the exercise effect, enhancing the flexibility of the user's cervical spine and spine, and ensuring the user's comfort. It is convenient and quick to use.

[0032] Specifically, brackets 2 (6) and 3 (7) are correspondingly arranged at the front and rear of the housing 1 to support the drive mechanism. Brackets 2 (6) and 3 (7) correspond to the hand support device 12 and the foot support device 13, respectively. Furthermore, displacement devices 1 (15) connected to the hand support device 12 and the foot support device 13 are respectively located on the left and right sides of brackets 2 (6) and 3 (7). Bracket 1 (4) is mounted on bracket 2 (6) and located in front of it. The head support device includes displacement device 2 (16) and a head tray 14. Displacement device 2 (16) is horizontally positioned on top of bracket 1 (4), and the head tray 14 is mounted on displacement device 2 (16). Driven by the drive mechanism controlled by control mechanism 5, the four displacement devices 1 (15) and 2 (16) reciprocate along the length and width of the housing 1, respectively. This allows the four displacement devices 1 (15) to drive the two hand support devices 12 and the two foot support devices 13 to reciprocate along the length of the housing 1, and the displacement devices 2 (16) to drive the head tray 14 to reciprocate along the width of the housing 1.

[0033] like Figure 3As shown, the displacement device 16 includes a lead screw 16-1, a nut 16-2, and a support 16-3. The lead screw 16-1 is mounted on the horizontal rod of the support 4 via a double bearing seat and is connected to the drive mechanism. The double bearing seat is a bearing seat symmetrically arranged on the support 4. The nut 16-2 is sleeved on the lead screw 16-1 and is slidably connected to the horizontal rod of the support 4. The support 16-3 is mounted on the nut 16-2 and supports the bottom of the head tray 14. When the lead screw 16-1 rotates alternately forward and backward under the drive mechanism controlled by the control mechanism 5, the nut 16-2 can move back and forth along the length direction of the lead screw 16-1, thereby driving the head tray 14 to move back and forth along the width direction of the box 1. When the user places their chin on the head tray 14, the head tray 14 can drive their cervical spine to move left and right for exercise. To enhance user comfort, the top of the cover plate 2 is provided with a torso support seat 3 that is adapted to the head tray 14, and the head tray 14 is covered with a soft pad and has a groove in the center that is adapted to the human chin.

[0034] The drive mechanism includes a drive shaft 11, driven shaft one 8, driven shaft two 9, driven shaft three 10, a chain drive, and a belt drive. Driven shaft two 9 and driven shaft one 8 are respectively mounted on bracket two 6 via double bearing seats, and driven shaft three 10 is also mounted on bracket three 7 via double bearing seats. The double bearing seats are symmetrically arranged on bracket two 6 or bracket three 7. The chain drive is connected to the control mechanism 5 via the drive shaft 11 and drives driven shaft one 8 and driven shaft three 10 to rotate. The control mechanism 5 is located between bracket two 6 and bracket three 7. The belt drive is connected to driven shaft one 8 and drives driven shaft two 9 and lead screw 16-1 to rotate, thus forming a complete drive mechanism system with the control mechanism 5 as the power source. Furthermore, the two ends of driven shaft 18 and driven shaft 310, as well as the same-side end of driven shaft 29 and lead screw 16-1, are respectively connected to their corresponding bearing seats. That is, the two ends of driven shaft 18 and driven shaft 310 are connected to their corresponding bearing seats, the same-side end of driven shaft 29 and lead screw 16-1 is connected to their corresponding bearing seats, while the other ends of both are not connected to their corresponding bearing seats.

[0035] Specifically, the chain drive device is located on one side of the second bracket 6, including a first chain drive assembly 17 and a second chain drive assembly 18. Both chain drive assemblies include two sprockets and a chain mounted on the two sprockets. The first chain drive assembly 17 is connected to the drive shaft 11 through its drive sprocket and to the driven shaft 8 through its output sprocket. The second chain drive assembly 18 is connected to the driven shaft 8 and the driven shaft 10 through its two output sprockets, thereby transmitting the kinetic energy generated by the control mechanism 5 to the driven shaft 8 and the driven shaft 10 through the drive shaft 11. When the frequency converter in the control mechanism 5 controls the motor to alternately rotate forward and reverse, the driven shaft 8 and the driven shaft 10 also alternately rotate forward and reverse.

[0036] The belt drive device includes belt drive assembly 19 and belt drive assembly 20. Both belt drive assemblies include two pulleys and a belt fitted onto the two pulleys. Belt drive assembly 19 is connected to driven shaft 8 via its drive pulley and to driven shaft 9 via its output pulley. Preferably, belt drive assembly 19 is located in the middle of bracket 26, that is, in the middle of driven shaft 8 and driven shaft 9. Belt drive assembly 20 is connected to driven shaft 9 and the end of lead screw 16-1 passing through the bearing housing via its two output pulleys. Belt drive assembly 20 is also located on one side of bracket 26, thereby transmitting the kinetic energy generated by control mechanism 5 to driven shaft 9 and lead screw 16-1 via driven shaft 8. When the frequency converter in control mechanism 5 controls the motor to alternately rotate forward and reverse, driven shaft 9 and lead screw 16-1 also alternately rotate forward and reverse. A channel adapted to belt drive assembly 20 is provided on the housing 1 or cover plate 2, or both in combination.

[0037] like Figure 4 As shown, the displacement device 15 includes a support 15-1, two slide rails 15-2, a rack 15-3, and a gear 15-4. The top of the support 15-1 is symmetrically provided with slide rails 15-2. The rack 15-3 is slidably disposed between the two slide rails 15-2 and is connected to the hand support device 12 or the foot support device 13. The gear 15-4 is adapted to the rack 15-3 and is connected to the end of the driven shaft 8 or the driven shaft 3 10.

[0038] To achieve the function of opposite movement directions between the two hand support devices 12 and between the two hand support devices 12 and the foot support device 13 on the same side, the displacement devices 15 are arranged symmetrically in pairs. The racks 15-3 of the two displacement devices 15 located on the same diagonal mesh with the corresponding gears 15-4 respectively. The racks 15-3 of the other two displacement devices 15 located on the same diagonal mesh with the directional gears 21 rotatably set on the inner wall of the housing 1. The two directional gears 21 mesh with the corresponding gears 15-4 respectively. The rotation directions of the two directional gears 21 and the two gears 15-4 they mesh with are opposite, so that the racks 15-3 of the two sets of displacement devices 15 located on different diagonals move in opposite directions.
