Description

Technical Field

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

[0002] Crawling exercises offer numerous health benefits, including improved cardiovascular function, enhanced heart and lung capacity, and smoother breathing. They can also help prevent lumbar spine problems, reduce the risk of osteoporosis, and increase the mobility of all joints. Therefore, crawling fitness equipment, with its ease of use and ability to provide a full-body workout, has become a popular choice for indoor exercise.

[0003] In existing technologies, dampers need to be installed on crawling fitness devices. However, the dampers in existing crawling fitness devices have complex structures, and their damping force cannot be easily adjusted, thus failing to meet the needs of users with different physical conditions and resulting in low adaptability of the crawling fitness devices. Furthermore, existing crawling fitness devices have a simple structure and cannot meet the diverse exercise needs of users.

[0004] Furthermore, crawling is a forward movement involving the alternating, repetitive, and whole-body movement of all four limbs. In existing crawling fitness devices, the linkage between the upper limb handles and the lower limb leg supports is poor, which reduces the customer's experience. Utility Model Content

[0063] This application discloses a crawling fitness device.

[0064] Please see Figures 1-4 As shown, the crawling fitness device includes a base 1, upper limb handles 2, lower limb leg supports 3, dampers 4, and a transmission mechanism 5. The base 1 is suitable for placement on the ground. The upper limb handles 2 are located at the front of the base 1 and are suitable for supporting the user's upper limbs. Two lower limb leg supports 3 are slidably mounted at the left and right ends of the rear of the base 1, respectively. The lower limb leg supports 3 are suitable for supporting the user's lower limbs. The dampers 4 are mounted on the base 1 and positioned between the two lower limb leg supports 3. The dampers 4 are suitable for providing damping force to the sliding lower limb leg supports 3.

[0065] The damper 4 includes a permanent magnet frame 41 and a flywheel 42. One end of the permanent magnet frame 41 has a mounting groove, and the other end is movably mounted on the base 1 via a screw 43. Permanent magnets are provided on the inner walls of both sides of the mounting groove to generate a magnetic field. The flywheel 42 is rotatably mounted on the base 1, and a portion of the flywheel 42 is placed within the magnetic field.

[0066] In this embodiment, the permanent magnet frame 41 has an n-shaped cross-section. A mounting groove is formed at the lower end of the permanent magnet frame 41, and the upper end of the permanent magnet frame 41 is mounted on the base 1 via a screw 43. A flywheel 42 is positioned below the permanent magnet frame 41, with a portion of its edge within the mounting groove. Permanent magnets are distributed on both sides of the flywheel 42. The screw 43 is adapted to adjust the relative position of the flywheel 42 and the magnetic field. Specifically, the user can rotate the screw 43 to raise and lower the permanent magnet frame 41, thereby adjusting the relative distance between the axis of the flywheel 42 and the permanent magnet frame 41.

[0067] Please see Figure 3 and Figure 8 As shown, the transmission mechanism 5 is mounted on the base 1. The lower limb leg support 3 is connected to the flywheel 42 via the transmission mechanism 5. When the lower limb leg support 3 slides back and forth, the lower limb leg support 3 drives the flywheel 42 to rotate via the transmission mechanism 5, thereby cutting the magnetic field lines. According to Faraday's law of electromagnetic induction, the rotating flywheel 42 cuts the magnetic field lines, thus generating a damping force on the flywheel 42, which in turn provides a damping force to the lower limb leg support 3.

[0068] In this embodiment, the flywheel 42 is a metal flywheel. When the metal flywheel moves in the magnetic field, it cuts the magnetic field lines, thereby generating an induced current inside the metal. This induced current is subject to the Ampere force, which always opposes the movement of the metal, thus generating resistance opposite to the direction of the flywheel 42's movement; that is, the magnetic field generates a damping force on the flywheel 42.

[0069] Preferably, the flywheel 42 is an aluminum alloy flywheel.

[0070] This invention adjusts the relative position between the flywheel 42 and the permanent magnet frame 41 via screw 43, thereby adjusting the damping force between the two lower limb leg supports 3 to meet the needs of users with different physical conditions and improve the adaptability of the crawling fitness device. The damper 4 has a simple structure and is easy to maintain and replace.

[0071] Please see Figure 1 and Figures 6-8 As shown, the base 1 includes a base frame 11, a front mounting bracket 12, and a rear mounting bracket 13. The front mounting bracket 12 is located at the front of the base frame 11. The front mounting bracket 12 is fixed to the front of the base frame 11 and positioned above the base frame 11. The rear mounting bracket 13 is mounted to the rear of the base frame 11 via a first lead screw and a first slider, and positioned above the base frame 11. The first lead screw extends in the front-to-back direction. The user can rotate the first lead screw to move the rear mounting bracket 13 in the front-to-back direction, thereby adjusting the distance between the front mounting bracket 12 and the rear mounting bracket 13.

[0072] There are two upper limb handles 2, which are slidably mounted on the left and right ends of the front mounting frame 12. Two lower limb leg supports 3 are slidably mounted on the left and right ends of the rear mounting frame 13.

[0073] Specifically, in this embodiment, the rear mounting frame 13 includes a rear fixed frame 131, two rear movable frames 132, and a rear protective cover 133. The rear fixed frame 131 is mounted on the rear part of the base frame 11 via a first lead screw and a first slider, and the rear fixed frame 131 is slidably connected to the base frame 11. The two rear movable frames 132 are respectively disposed at the left and right ends of the rear fixed frame 131 and are positioned above the rear fixed frame 131. The rear movable frames 132 are mounted on the rear fixed frame 131 via a second lead screw and a second slider, and the rear movable frames 132 are slidably connected to the rear fixed frame 131. The second lead screw extends in the left-right direction. The two lower limb leg supports 3 are respectively slidably disposed on the corresponding rear movable frames 132 and positioned above the rear movable frames 132. The user can rotate the second lead screw to move the rear movable frames 132 in the left-right direction to adjust the distance between the two rear movable frames 132, and thus adjust the distance between the two lower limb leg supports 3. The rear protective cover 133 is positioned above the rear fixed frame 131 and between the two rear movable frames 132. The rear protective cover 133 and the rear fixed frame 131 together form a rear receiving cavity.

[0074] The lower limb leg support 3 is slidably mounted on the top of the corresponding rear movable frame 132.

[0075] In this embodiment, there is one damper 4. Please refer to [link / reference]. Figure 5 and Figure 8 As shown, the damper 4 is placed in the rear receiving cavity, and the flywheel 42 is rotatably mounted on the base 1 via the main shaft 44. The main shaft 44 extends in the front-to-back direction. The main shaft 44 is rotatably mounted on the rear fixed frame 131 via a bearing seat. The rear end of the main shaft 44 is fixedly connected to the flywheel 42, and the front end of the main shaft 44 is provided with a driven bevel gear 441. The lower limb leg support 3 is driven by the driven bevel gear 441 via a transmission mechanism 5. The permanent magnet frame 41 is placed in the rear receiving cavity and is slidably mounted on the rear protective cover 133. The screw 43 is vertically mounted, and its lower end is threadedly connected to the upper end of the permanent magnet frame 41. The upper end of the screw 43 passes through the rear protective cover 133 and extends outside the rear protective cover 133. The screw 43 is rotatably mounted on the rear protective cover 133 via a stop block 46. Users can rotate the upper end of the screw 43 to raise and lower the permanent magnet frame 41, thereby adjusting the relative distance between the axis of the flywheel 42 and the permanent magnet frame 41.

[0076] Furthermore, the damper 4 also includes a guide rod 45. The permanent magnet frame 41 is slidably mounted on the rear protective cover 133 via the guide rod 45. Specifically, the guide rod 45 is placed inside the rear receiving cavity. The guide rod 45 is vertically arranged, with its upper end fixed to the rear protective cover 133 and its lower end slidably connected to the permanent magnet frame 41. The guide rod 45 is adapted to limit the direction of movement of the permanent magnet frame 41. By rotating the upper end of the screw 43, the permanent magnet frame 41 can only be raised and lowered under the action of the guide rod 45, but cannot be rotated. In this embodiment, there are two guide rods 45.

[0077] Furthermore, to facilitate the rotation of the screw 43, a knob 431 is provided on the screw 43. The knob 431 is exposed outside the rear protective cover 133 and is positioned above the rear protective cover 133.

[0078] The front mounting bracket 12 and the rear mounting bracket 13 are structurally similar. Please refer to [link / reference]. Figure 1 and Figures 6-8 As shown, the front mounting bracket 12 includes a front fixed bracket 121, two front movable brackets 122, and a front protective cover 123. The front fixed bracket 121 is fixed to the front of the base frame 11. The two front movable brackets 122 are respectively disposed at the left and right ends of the front fixed bracket 121 and positioned above it. The front fixed bracket 121 is mounted on the front fixed bracket 121 via a third lead screw and a third slider, and the front fixed bracket 121 is slidably connected to the front fixed bracket 121. The third lead screw extends in the left-right direction. Two upper limb handles 2 are slidably disposed on their respective front movable brackets 122 and positioned above them. The user can rotate the third lead screw to move the front movable brackets 122 in the left-right direction, thereby adjusting the distance between the two front movable brackets 122 and consequently, the distance between the two upper limb handles 2. The front protective cover 123 covers the front fixed bracket 121 and is positioned between the two front movable brackets 122. The front protective cover 123 and the front movable frame 122 form a front receiving cavity.

[0079] The upper limb handle 2 is slidably mounted on the top of the corresponding front movable frame 122.

[0080] Further, please refer to Figure 3 As shown, the lower limb leg support 3 has a first rack 31 extending in the front-to-back direction at its bottom. The first rack 31 is connected to the flywheel 42 via a transmission mechanism 5. The front end of the lower limb leg support 3 has a knee pad 32, which is suitable for supporting the user's knees and improving comfort. The rear end of the lower limb leg support 3 has a foot support 33, which is suitable for supporting the user's feet and limiting the position of the user's feet.

[0081] The distance between the knee pad 32 and the foot support 33 is adjustable to accommodate users with different leg lengths. In this embodiment, the front end of the foot support 33 is connected to the lower limb leg support 3 via a positioning bolt and a waist hole. The foot support 33 has a waist hole extending in the front-back direction. The user can adjust the distance between the knee pad 32 and the foot support 33 by adjusting the relative position of the positioning bolt and the waist hole.

[0082] Further, please refer to Figure 2 , Figure 3 and Figure 8 As shown, the transmission mechanism 5 includes two first gear shafts 51. The two first gear shafts 51 are rotatably mounted on the base 1 and positioned between the corresponding lower limb leg support 3 and the main shaft 44. Specifically, one end of the first gear shaft 51 is rotatably mounted on the corresponding rear movable frame 132, and the other end extends into the rear protective cover 133 and is rotatably mounted on the rear fixed frame 131. In this embodiment, the first gear shaft 51 is a telescopic shaft, including a spline shaft and a spline sleeve. The spline shaft is inserted into the spline sleeve. The first gear shaft 51 adapts to the distance between the two rear movable frames 132 through the cooperation between the spline shaft and the spline sleeve. The first gear shaft 51 extends in the left-right direction. One end of the first gear shaft 51 is provided with a first gear 511 that meshes with the corresponding first rack 31. The other end of the first gear shaft 51 is provided with a first bevel gear 512 that meshes with the corresponding driven bevel gear 441. The first bevel gear 512 is located in the rear receiving cavity.

[0083] In this embodiment, when the user drives the lower limb leg support 3 to slide back and forth, the first rack 31 of the lower limb leg support 3 drives the flywheel 42 to rotate through the first gear shaft 51 to cut the magnetic field lines, thereby providing damping force to the lower limb leg support 3. At the same time, the two first gear shafts 51 are linked through the driven bevel gear 441, so that the lower limb leg support 3 drives the other lower limb leg support 3 to slide back and forth.

[0084] Furthermore, the lower limb leg support 3 can also be linked with the upper limb handle 2 via the transmission mechanism 5. For details, please refer to [link / reference needed]. Figure 2 , Figure 3 and Figure 8As shown, the bottom of the upper limb handle 2 is provided with a second rack 21 extending in the front-to-back direction. The transmission mechanism 5 also includes a transmission shaft 52 and two second gear shafts 53. The transmission shaft 52 extends in the front-to-back direction. Both ends of the transmission shaft 52 are rotatably mounted on the front mounting bracket 12 and the rear mounting bracket 13, respectively. The transmission shaft 52 is positioned between the two first gear shafts 51. The front and rear ends of the transmission shaft 52 are respectively provided with a front bevel gear 521 and a rear bevel gear 522, and the front bevel gear 521 and the rear bevel gear 522 are respectively located in the front receiving cavity and the rear receiving cavity. The rear bevel gear 522 meshes with the first bevel gears 512 of the two first gear shafts 51. The two second gear shafts 53 are rotatably mounted on the base 1 and positioned on the left and right sides of the transmission shaft 52. One end of the second gear shaft 53 is rotatably mounted on the corresponding front movable bracket 122, and the other end extends into the front protective cover 123 and is rotatably mounted on the front fixed bracket 121. One end of the second gear shaft 53 is provided with a second gear 531 that meshes with the corresponding second rack 21, and the other end of the second gear shaft 53 is provided with a second bevel gear 532. The second bevel gear 532 is placed in the front receiving cavity. The front bevel gear 521 meshes with the second bevel gears 532 of the two second gear shafts 53 respectively.

[0085] In this embodiment, when the user drives the lower limb leg support 3 to slide back and forth, the first rack 31 of the lower limb leg support 3 drives the transmission shaft 52 to rotate through the first gear shaft 51, which in turn drives the two second gear shafts 53 to rotate, so that the upper limb handle 2 can slide back and forth. That is, the crawling fitness device can assist the user's four limbs to work together.

[0086] In this embodiment, the second gear shaft 53 is a telescopic shaft to accommodate the distance between the two front movable frames 122. The drive shaft 52 is a telescopic shaft to accommodate the distance between the front fixed frame 121 and the rear fixed frame 131.

[0087] Furthermore, both the first gear 511 and the second gear 531 are helical gears. Compared with spur gears, helical gears have unique advantages such as higher transmission efficiency, stronger load capacity, lower noise, and better smoothness.

[0088] Furthermore, for ease of maintenance, please refer to [link / reference]. Figure 1 As shown, a maintenance hole is provided on the front protective cover 123 to expose the front bevel gear 521 and the second bevel gear 532. A maintenance hole is also provided on the rear protective cover 133 to expose the rear bevel gear 522, the first bevel gear 512 and the driven bevel gear 441.

[0089] Further, please refer to Figure 1As shown, the base 1 also includes a conveyor protective cover 14. The conveyor protective cover 14 covers the outside of the drive shaft 52. The two ends of the conveyor protective cover 14 are respectively inserted into the front protective cover 123 and the rear protective cover 133, and are respectively fixed on the front fixed frame 121 and the rear fixed frame 131.

[0090] Further, please refer to Figure 1 As shown, the crawling fitness device also includes a fixed grip 6 and an elbow support 7. The fixed grip 6 is fixed to the middle of the front frame 121. The fixed grip 6 is suitable for the user to hold. The elbow support 7 is fixed to the middle of the front frame 121 and is located behind the fixed grip 6. The elbow support 7 is suitable for supporting the user's elbow.

[0091] In this embodiment, there are two fixed grips 6 and two elbow supports 7.

[0092] The working principle of this utility model is as follows:

[0093] When a user needs to exercise their limbs, their lower limbs are placed on the corresponding lower limb leg rests 3 and their upper limbs are placed on the corresponding upper limb handles 2. When the user drives the lower limb leg rest 3 to slide back and forth, the lower limb leg rest 3 drives the other lower limb leg rest 3 to slide back and forth through the transmission mechanism 5, drives the flywheel 42 to cut the magnetic field, and drives the two upper limb handles 2 to slide back and forth, so that the user's limbs can move in unison.

[0094] When a user needs to exercise their limbs, their lower limbs are placed on the corresponding lower limb leg rests 3, and their upper limbs are placed on the fixed grips 6, so that the user can exercise only their lower limbs.

[0095] In summary, this invention adjusts the relative position between the flywheel and the permanent magnet frame using a screw adjustment mechanism to regulate the damping force between the two lower limb leg supports, thereby meeting the needs of users with different physical conditions and improving the adaptability of the crawling fitness device. The lower limb leg supports are linked to the upper limb handles via a transmission mechanism, ensuring better linkage between the upper limb handles and the lower limb leg supports and enhancing the user experience. Users can exercise only their lower limbs by using the fixed grips in conjunction with the lower limb leg supports, or exercise all four limbs by using the upper limb handles in conjunction with the lower limb leg supports, satisfying different exercise needs.
