Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, in particular to a crawling fitness equipment. Background Art

[0002] As early as 2,000 years ago, Hua Tuo, a famous doctor in the Han Dynasty, imitated the crawling movements of five animals: bears, tigers, monkeys, deer, and birds, and compiled a set of exercise methods for preventing diseases, curing diseases, and prolonging life - "Five Animal Exercises", which has been used to this day. This animal-like crawling movement can distribute the body's weight to the limbs, so that the head, heart, lungs and other organs are at almost the same height, and has different degrees of exercise effects on the neck, shoulders, spine, internal organs and other organs, increasing blood flow, reducing blood lipid accumulation, and enhancing blood vessel elasticity. It can effectively improve blood circulation in the brain and the whole body and reduce osteoporosis.

[0003] Since people are restricted by factors such as the venue and environment when performing crawling exercises, crawling auxiliary equipment is needed. According to observations, when animals crawl, their limbs do not just move back and forth on a plane, but move in a circumferential direction, front and back, up and down. The front and back limbs sometimes move synchronously, and sometimes not synchronously. The limbs are flexible, thereby driving the lumbar spine, cervical spine and other organs to move together. The crawling exercise aids currently available on the market only make the upper and lower limbs of the human body move back and forth in parallel or only make the upper and lower limbs of the human body move synchronously in a circumferential direction. Therefore, it is still impossible to achieve the purpose of making human movement closer to animal crawling. Summary of the invention

[0004] In view of this, it is necessary to provide a crawling fitness device that can make human body movement relatively closer to animal crawling.

[0005] A crawling fitness device comprises a support frame fixed on the ground, and an upper limb movement component and a lower limb movement component arranged on the support frame; the upper part of the support frame is an arc with the convex surface facing upward, which is convenient for contacting and supporting the abdomen of the human body; the upper limb movement component comprises a hand crank, an upper limb driven wheel disc, and a front transmission part, the hand crank is connected to the upper limb driven wheel disc through the front transmission part, the hand crank performs circular motion through human hand cranking and drives the upper limb driven wheel disc to rotate; the lower limb movement component comprises a foot pedal, a lower limb driven wheel disc, and a rear transmission part, the foot pedal is connected to the lower limb driven wheel disc through the rear transmission part, the foot pedal performs circular motion through human foot pedaling and drives the lower limb driven wheel disc to rotate; the upper limb driven wheel disc and the lower limb driven wheel disc can realize synchronous or step-by-step motion.

[0006] Preferably, the crawling fitness machine also includes an abdominal pad, which is arranged on the upper part of the support frame. The upper surface of the abdominal pad is an arc-shaped concave surface, which is convenient for supporting the human abdomen, preventing the body from slipping during exercise and causing danger, and reducing the pressure of the whole body weight on the limb joints.

[0007] Preferably, the crawling fitness device also includes a synchronous pressing wheel, which is rotatably connected to the support frame, and the synchronous pressing wheel can move in a direction close to or away from the upper limb driven wheel disc and the lower limb driven wheel disc, and the upper limb driven wheel disc is coaxial and concentric with the lower limb driven wheel disc, and the diameters of the two are exactly the same. After the synchronous pressing wheel moves in a direction close to the outer edge arc surface of the upper limb driven wheel disc and the outer edge arc surface of the lower limb driven wheel disc until it contacts and presses against the outer edge arc surfaces of both at the same time, the upper limb driven wheel disc and the lower limb driven wheel disc realize synchronous rotation, so that the hand crank and the foot pedal rotate at the same time, thereby realizing synchronous movement of the upper limb and lower limb of the human body; the synchronous pressing wheel moves in a direction away from the upper limb driven wheel disc and the lower limb driven wheel disc, and the upper limb driven wheel disc and the lower limb driven wheel disc realize step-by-step rotation, so that the hand crank and the foot pedal rotate step-by-step, thereby realizing flexible step-by-step movement of the upper limb and lower limb of the human body.

[0008] Preferably, the crawling fitness machine also includes a damping assembly, which is arranged on a support frame. The damping assembly includes two dampers respectively arranged near the outer edge arc surface of the upper limb driven wheel disc and the outer edge arc surface of the lower limb driven wheel disc, respectively increasing the resistance to the rotation of the upper limb driven wheel disc and the lower limb driven wheel disc, thereby increasing the resistance to the hand crank and the foot pedal.

[0009] Preferably, an adjusting long hole is opened on the support frame, and the hand crank is clamped in the adjusting long hole and can move along the adjusting long hole to adjust the height of the hand crank.

[0010] Preferably, the abdomen pad is spherically hinged to the support frame.

[0011] Preferably, the parts where the adjusting long hole and the hand crank contact each other are provided with magnets, and the two are in contact and magnetically connected to prevent the hand crank from separating from the adjusting long hole during movement and causing danger.

[0012] Preferably, the hand crank and the foot pedal are both Z-shaped.

[0013] Preferably, an anti-slip pad is provided at one end of the hand crank to facilitate human hand gripping and applying force.

[0014] Preferably, an anti-skid pad is provided at the position where the support frame contacts the ground, so as to increase the friction between the crawling fitness device and the ground and increase the stability during use.

[0015] The present invention adopts the above technical solution, and its beneficial effect is that the synchronous or step-by-step movement of the upper limb driven wheel disc and the lower limb driven wheel disc drives the hand crank and the foot pedal to achieve synchronous or step-by-step movement, so that the human limbs can move synchronously or step-by-step in a circumferential direction according to actual needs. The cooperation of the upper limb driven wheel disc and the front transmission part makes the hand crank produce a predetermined resistance during the rotation process, so that the upper limbs of the human body can absorb the force during the movement, achieving the purpose of simulating the crawling of the animal's forelimbs; the cooperation of the lower limb driven wheel disc and the rear transmission part makes the foot pedal produce a predetermined resistance during the rotation process, so that the lower limbs of the human body can absorb the force during the movement, achieving the purpose of simulating the crawling of the animal's hind limbs. The overall design of this device makes the simulated crawling action of the human body closer to the crawling of animals. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please see Figure 1 , Figure 3 Furthermore, the crawling fitness machine 10 also includes an abdominal pad 50, which is arranged on the upper part of the support frame 20. The upper surface of the abdominal pad 50 is an arc-shaped concave surface, which is convenient for supporting the human abdomen, preventing the body from slipping during exercise and causing danger, and reducing the pressure of the whole body weight on the limb joints.

[0029] Please see Figure 7 , Figure 8Furthermore, the crawling fitness device 10 further includes a synchronous pressing wheel 60, which is rotatably connected to the support frame 20. The synchronous pressing wheel 60 can move toward or away from the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42. The upper limb driven wheel disc 32 is coaxial and concentric with the lower limb driven wheel disc 42, and the diameters of the two are exactly the same. The synchronous pressing wheel 60 moves toward the outer edge arc surface of the upper limb driven wheel disc 32 and the outer edge arc surface of the lower limb driven wheel disc 42 until it is simultaneously with the outer edge arc surfaces of the two. After contact and tightening, the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42 realize synchronous rotation, so that the hand crank 31 and the foot pedal 41 rotate at the same time, thereby realizing synchronous movement of the upper and lower limbs of the human body; the synchronous pressure wheel 60 moves away from the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42, and the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42 realize step-by-step rotation, so that the hand crank 31 and the foot pedal 41 rotate step-by-step, thereby realizing flexible step-by-step movement of the upper and lower limbs of the human body.

[0030] Please see Figure 7 , Figure 8Furthermore, the synchronous pressure wheel 60 includes a connecting portion 61, an extension portion 62, a pressure wheel 63, a lower rotating block 64, an upper rotating block 65, a fixed block 66, a limiting plate 67, and a lever 68. One end of the connecting portion 61 is fixed to the support frame 20, the extension portion 62 is a triangle, the end of the first angle of the extension portion 62 is rotatably connected to the connecting portion 61, the end of the second angle is rotatably connected to the axis of the pressure wheel 63, and the end of the third angle is rotatably connected to one end of the lower rotating block 64. The other end of the lower rotating block 64 is rotatably connected to one end of the upper rotating block 65, and the other end of the upper rotating block 65 is rotatably connected to the fixed block 66.

The limiting block is fixed on the extension portion 62 and is arranged close to the lower rotating block 64. The rotating lever 68 drives the other end of the upper rotating block 65 to rotate around the fixed block 66 as the axis, and one end of the upper rotating block 65 moves upward or downward along the rotation arc of the other end, driving the other end of the lower rotating block 64 to rotate around the other end of the upper rotating block 65 as the axis and move upward or downward in an arc, thereby driving one end of the lower rotating block 64 to rotate around the end of the second corner of the extension part 62 as the axis and move upward or downward in an arc, thereby driving the end of the third corner of the extension part 62 to move upward or downward in an arc, and the end of the first corner of the extension part 62 rotates around the connecting part 61 as the axis, thereby driving the pressure wheel 63 to move upward or downward in an arc, so that the pressure wheel 63 moves away from or close to the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42. The pressing wheel 63 moves upward in an arc, that is, moves away from the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42, and does not contact the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42, and the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42 move in steps; the pressing wheel 63 moves downward in an arc, that is, moves toward the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42, and contacts and presses against the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42, and the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42 move synchronously. The limit plate 67 limits the upward or downward movement of the lower rotating block 64.

[0031] Please see Figures 1 to 3 Furthermore, the crawling fitness machine 10 also includes a damping assembly 70, which is arranged on the support frame 20. The damping assembly 70 includes two dampers respectively arranged at the outer edge arc surface of the upper limb driven wheel 32 and the outer edge arc surface of the lower limb driven wheel 42, respectively, to increase the resistance to the rotation of the upper limb driven wheel 32 and the lower limb driven wheel 42, thereby increasing the resistance to the hand crank 31 and the foot pedal 41.

[0032] Please see Figures 1 to 3, further, the damping assembly 70 also includes a connecting block 72, one end of the connecting block 72 is fixed on the support frame 20, and the other end is connected to the two dampers; a connecting plate 21 extends downward from the upper part of the support frame 20; the two dampers are exactly the same. Taking the damper corresponding to the upper limb driven wheel 32 as an example, the damper includes a damping block 711, a return spring 712, a damping rope 713, a rope shaft 714, and a knob 715. The damping block 711 is a triangular shape, and the end of the first corner of the damping block 711 is rotatably connected to the connecting block 72, the end of the second corner is fixedly connected to one end of the return spring 712 and one end of the damping rope 713, and the end of the third corner is arranged near the upper limb driven wheel 32 and the lower limb driven wheel 42, the other end of the return spring 712 is fixedly connected to the connecting block 72, and the return spring 712 and the damping rope 713 are located on the same straight line, The other end of the damping rope 713 is wound around the rope winding shaft 714, one end of the rope winding shaft 714 passes through the connecting plate 21 and is fixedly connected to the knob 715, and the rope winding shaft 714 is rotatably connected to the connecting plate 21. The forward rotation of the knob 715 drives the damping rope 713 to be wound around the rope winding shaft 714 in the forward direction, and the reverse rotation of the knob 715 drives the damping rope 713 to be wound out of the rope winding shaft 714 in the reverse direction, driving the end of the first corner of the damping block 711 to rotate around the connecting block 72 as the axis, thereby driving the end of the third corner of the damping block 711 to move in the direction of approaching or moving away from the upper limb driven wheel 32, and the damping block 711 can be made to contact or leave the upper limb driven wheel 32 by rotating the knob 715. The resistance of the damping block 711 and the upper limb driven wheel 32 can also be adjusted by rotating the knob 715, and the contact portion of the damping block 711 and the upper limb driven wheel 32 is provided with a cushion 716. The damper corresponding to the upper limb driven wheel disc 32 and the damper corresponding to the lower limb driven wheel disc 42 are two independent entities and do not affect each other.

[0033] Please see Figure 1 , Figure 3 , Figure 4 The locking cam 330 is provided on the support frame 20 to lock the locking cam 331 with a spring 350 which is provided on the support frame 20. The locking cam 330 is provided on the support frame 20 to lock the locking cam 331 with a spring 350 which is provided on the support frame 20.

[0034] Please see Figure 1 , Figure 3 Furthermore, the abdominal pad 50 is spherically hinged to the support frame 20.

[0035] Furthermore, the portion of the support frame 20 where the adjusting teeth are provided is provided with magnetism, and the buckle 311 is also provided with magnetism, and the two are in contact and magnetically connected to prevent the buckle 311 from being separated from the adjusting teeth during the movement of the hand crank 31.

[0036] Please see Figures 1 to 6 Furthermore, the hand crank 31 and the foot pedal 41 are both Z-shaped. The hand crank 31 and the foot pedal 41 are both arranged opposite to each other, each hand crank 31 is provided with a buckle 311, and two symmetrical plates 23 are arranged in parallel on the support frame 20, and the two symmetrical plates 23 are provided with adjustment long holes 22, and the ends of the two hand cranks 31 pass through the adjustment long holes 22 on the two symmetrical plates 23 and are connected to each other.

[0037] Furthermore, an anti-slip pad is provided at one end of the hand crank 31 to facilitate hand gripping and applying force.

[0038] Please see Figure 1 , Figure 3 , Figure 4 Furthermore, an anti-skid pad is provided at the position where the support frame 20 contacts the ground to increase the friction between the crawling fitness device 10 and the ground and increase the stability during use.

[0039] Furthermore, the front transmission part 33 and the rear transmission part 43 both use a transmission method using a sprocket and a chain.

[0040] Furthermore, the shape of the support frame 20 is fan-shaped.

[0041] Please see Figure 1 , Figure 3 Furthermore, the crawling fitness machine 10 also includes a display screen 80, which is fixed on the support frame 20. The display screen 80 is electrically connected to the upper limb driven wheel 32 and the lower limb driven wheel 42 to display the rotation speed and number of rotations of both.

[0042] The structure of the device is relatively simple, easy and light. The overall height of the device is set at 0.8~1 meter, so that the exerciser is closer to the ground during the exercise of the device, which relatively increases the safety factor and reduces safety hazards.

[0043] When the device is used, the exerciser places the abdomen on the abdomen pad 50, adjusts the posture, holds the main hand crank 31 with both hands, and steps both feet on the two foot pedals 41 to start the circular motion of the upper limbs and lower limbs. When synchronous motion is required, the lever 68 is pulled to make the pressure wheel 63 contact and press the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42, so as to achieve the synchronous motion of the hand crank 31 and the foot pedal 41. When the resistance needs to be adjusted, the corresponding knob 715 is rotated to adjust the resistance of the upper limb driven wheel disc 32 or the lower limb driven wheel disc 42 to increase the resistance of the hand crank 31 or the foot pedal 41. When the upper limb driven wheel disc 32 and the lower limb driven wheel disc 42 move synchronously, the resistance of the hand crank 31 and the foot pedal 41 is the same, and only one of the knobs 715 corresponding to the two is adjusted, or the two knobs 715 corresponding to the two are adjusted to have similar resistance.

[0044] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
