Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment, and particularly relates to a hip bridge training device. Background Art

[0002] The buttocks are a very crucial part of the human body. Whether male or female, having a perky buttocks is a prerequisite for a good figure. Core strength includes abdominal strength and hip strength. These muscle groups are the connecting bridges of the entire body's strength, enabling better coordination of the upper and lower body strength. Therefore, hip training is a fundamental and important training in exercise. Common exercise methods include hip bridges and squats, and using a hip bridge training device can improve the training effect.

[0003] However, in the actual use process, there are still some problems in traditional and similar technical solutions:

[0004] 1. When exhausted after long-term training, the buttocks and the rotating frame are prone to suddenly drop, and a huge impact force will be generated when hitting the support frame at high speed. The existing structure cannot completely absorb the kinetic energy, there is a risk of lumbar spine overload injury, and there is a lack of an emergency stop and buffering mechanism;

[0005] 2. Although the pedal has anti-slip patterns, when the hip bridge is lifted, the ankles bend and the center of gravity moves backward, and the feet are prone to slide forward. Relying solely on the patterns cannot effectively limit the position, there is a lack of a dynamic locking mechanism, which is prone to unstable force application and poses a safety hazard;

[0006] 3. When the buttocks are pushed up, the trainer is prone to compensatory head-up, causing continuous compression of the cervical vertebrae. The existing cushion only provides support and lacks an active massage function. Long-term training is prone to cause neck muscle strain. Summary of the Invention

[0014] Preferably, the free end of the second pull rope is fixedly connected to a collar, and the collar is plugged into the counterweight rod.

[0015] Preferably, the back cushion is connected to a massage mechanism, which includes a fixed shell, a fixed shell installed on the back cushion, a sponge cover wrapped on the outer side of the fixed shell, a pair of mounting plates rotatably connected to the fixed shell, a resistance ball installed on the mounting plate, a second gear installed on the mounting plate close to the back cushion, a second air cylinder is installed at each second gear of the fixed shell, one end of the second air cylinder is slidably connected to a second piston rod, a rack is installed on the second piston rod, the rack is meshed with the second gear, and a communicating air pipe is installed on the second air cylinder.

[0016] Preferably, an air pumping assembly is connected to the support frame, and the air pumping assembly includes a first air cylinder. The first air cylinder is rotatably connected to the support frame, one end of the first air cylinder is slidably connected to a first piston rod, the first piston rod is rotatably connected to one end of the rotating bar, the free end of the air pipe is installed on the first air cylinder, and the air pipe is connected to the first air cylinder.

[0017] Preferably, one end of the support frame is rotatably connected to a pair of pedals, the end of the support frame close to the pedals is connected to a multi-section lever, one end of the pedal is connected to the multi-section lever, one end of the rotating bar is rotatably connected to a push rod, and the multi-section lever is hinged to the push rod.

[0018] Preferably, a protective mechanism is connected to the pedal, and the protective mechanism includes a fixed frame.

The back side of the pedal is rotatably connected to a protective plate, and one end of the protective plate slides through the fixed frame, and the protective plate is arc-shaped.

[0019] Preferably, a gear segment is installed on the arc-shaped outer edge of the protective plate, a rotating rod is rotatably connected to the pedal, a first gear is installed on the rotating rod, the first gear is engaged with the gear segment, a first winding disk is installed on the rotating rod, a first pull rope is wound around the first winding disk, the free end of the first pull rope is fixed to the support frame, and a first spring is installed between the protective plate and the pedal.

[0020] Compared with the prior art, the present invention provides a hip bridge training device with the following beneficial effects:

[0021] 1. When the buttocks pull the rotating frame upward through the restraint belt, the volute spring contracts, thereby winding up the second pull rope. During training, when suddenly exhausted, the buttocks lose strength and suddenly drop. Due to the large gravitational potential energy of the counterweight rod and the body, they have a relatively fast speed when descending and rotating, thus quickly pulling the second pull rope through the collar. The second winding disc rotates and releases, and through the speed change mechanism, the rotating disc is driven to rotate at a high speed. Under the action of centrifugal force, the ball bearings are thrown outward, and the fork will push the pressing rod outward, driving the limiting block to insert into the tooth groove of the sixth gear, thereby limiting the sixth gear, restricting the release of the second pull rope, and restricting the rotating frame and the counterweight rod from continuing to rotate downward, avoiding a large rebound force when the rotating frame falls and hits the support frame, enabling the rotating frame to hang in the air, and thus avoiding causing damage to the waist of the trainer.

[0022] 2. When the neck touches the sponge cover and the buttocks pull the rotating frame upward through the restraint belt, the rotating frame pushes the pressure rod downward, thereby driving the rotating bar to rotate. When the buttocks return downward, the rotating bar returns. During the swinging process of the rotating bar, the first piston rod is continuously pushed and pulled, thereby continuously squeezing the air inside the first air cylinder. Under the action of the air pipe, the first air cylinder is connected to the second air cylinder, thereby continuously pushing and pulling the second piston rod, driving the rack and the second gear to rotate reciprocally, and thus driving the installation disc to rotate. The two contact balls on the installation disc swing continuously, realizing the massage of the trainer's neck, thereby reducing the trainer's fatigue.

[0023] 3. During training, when the buttocks are lifted, the pedal tilts towards the end away from the cushion, facilitating the exertion of force. When the pedal tilts, the first pull rope becomes slack and the first spring contracts, thereby pulling the protective plate to rotate upward. The protective plate extends out of the fixed frame, thereby shielding and wrapping the sole of the foot, preventing the foot from sliding forward, and thus playing a role in anti-slip and limiting. When the buttocks are lowered, the pedal returns upward, the rotating rod and the first gear rotate, and through the gear section, the protective plate is driven to retract under the pedal, thereby hiding the protective plate and facilitating the movement of the foot on the pedal.

Therefore, it should not be construed as a limitation to the present invention.

[0038] Embodiment 1:

[0039] Referring to Figures 1-11 , a hip bridge training device includes a support frame 1. A training mechanism 2 is connected to the support frame 1. The training mechanism 2 includes a rotating frame 24. One end of the support frame 1 is rotatably connected to the rotating frame 24. A cushion 22 for leaning on is installed on the rotating frame 24. A rotating bar 26 is rotatably connected to the support frame 1. A pressure bar 25 is rotatably connected between the rotating bar 26 and the rotating frame 24. A pair of counterweight bars 23 for adding counterweight blocks to facilitate strength training are installed on the rotating frame 24. A limiting mechanism 4 is connected to the support frame 1. The limiting mechanism 4 includes a fixed box 42. The support frame 1 is provided with a fixed box 42 above the counterweight bar 23. A second winding reel 47 is rotatably connected inside the fixed box 42. A scroll spring 8 is installed between the second winding reel 47 and the fixed box 42, so as to facilitate the automatic winding of the second pulling rope 41 on the second winding reel 47. The second pulling rope 41 is wound around the second winding reel 47. The free end of the second pulling rope 41 is connected to the counterweight bar 23. A pressing rod 44 is slidably connected to the fixed box 42. A limiting block 48 is fixedly connected to the pressing rod 44. A fifth gear 63 is installed on one side of the second winding reel 47. The limiting block 48 is inserted into the teeth of the fifth gear 63, so as to facilitate restricting the rotation of the fifth gear 63 through the limiting block 48, thereby facilitating restricting the rotation of the second winding reel 47 and facilitating restricting the release of the second pulling rope 41.

[0040] The cam 466 is provided with a plurality of guide grooves 466 on one side of the cam 465, and a plurality of guide grooves 467 are provided on the inside of the guide grooves 466. The guide grooves 466 are provided with balls 468 and third springs 467. The third springs 467 limit the sliding of the balls 468. The balls 468 are close to the axis of the cam 465. The two ends of the third springs 467 respectively contact the balls 468 and the cam 465. The guide grooves 466 coincide with the diameter direction of the cam 465. When the cam 465 rotates, the balls 468 can be swung to slide outward, thereby squeezing the third springs 467. The depth of the guide grooves 466 close to the center of the cam 465 is less than the depth of the outer edge. The side of the cam 465 close to the balls 468 is slidably connected to the slide plate 464. When the cam 465 rotates, the balls 468 move into the guide grooves. 466 slides deep, and a shift fork 461 is connected to the fixed box 42 for rotation. The sliding of the sliding plate 464 is transmitted to the limit block 48 through the shift fork 461. A bearing 463 is installed on the outside of the sliding plate 464. The bearing 463 is a plane bearing, thereby reducing the friction between the sliding plate 464 and the shift fork 461. The two ends of the shift fork 461 respectively contact the outside of the bearing 463 and the end of the push rod 44. A second spring 46 is connected between the shift fork 461 and the fixed box 42. 2, so that when the ball 468 moves, the second spring 462 pushes the shift fork 461 and the sliding plate 464, and the other side of the shift fork 461 pushes the pressing rod 44, thereby controlling the limit block 48 to limit the position. A speed change mechanism 6 is connected between the fifth gear 63 and the rotating disk 465, thereby amplifying the pulling of the second pull rope 41, so that when the second winding disk 47 rotates one circle, the rotating disk 465 will rotate several circles, thereby facilitating the separation of the ball 468 and facilitating the driving of the shift fork 461.

[0041] In the present invention, a control knob 45 is threadedly connected to the fixed box 42, and one end of the control knob 45 extends into the interior of the fixed box 42. The two ends of the second spring 462 respectively contact the control knob 45 and the shift fork 461. By rotating the control knob 45, the second spring 462 can be squeezed, thereby controlling the force of the sliding plate 464 squeezing the rotating plate 465, so that a smaller rotation speed can be used to throw off the ball 468.

[0042] In the present invention, the speed change mechanism 6 includes a sixth gear 64, the sixth gear 64 is installed on one side of the rotating disk 465, the internal rotation of the fixed box 42 is connected to the third gear 61, and a coaxial fourth gear 62 is installed on one side of the third gear 61. The fourth gear 62 is engaged with the fifth gear 63, and the sixth gear 64 is engaged with the third gear 61. The diameter of the third gear 61 is larger than the diameter of the sixth gear 64, and the diameter of the fifth gear 63 is larger than the diameter of the fourth gear 62, thereby achieving the purpose of speed change.

[0043] In the present invention, a collar 43 is fixedly connected to the free end of the second drawstring 41, and the collar 43 is inserted into the counterweight rod 23, thereby facilitating the connection between the second drawstring 41 and the counterweight rod 23.

[0044] Embodiment 2:

[0045] On the basis of Embodiment 1, a hip bridge training device, a massage mechanism 5 is connected to the cushion 22. The massage mechanism 5 includes a fixed shell 55. The fixed shell 55 is installed on the cushion 22. A sponge cover 51 is wrapped around the outside of the fixed shell 55, thereby increasing the comfort. A pair of mounting disks 7 are rotatably connected to the fixed shell 55. A contact ball 54 is installed on the mounting disk 7. A second gear 57 is installed on the side of the mounting disk 7 close to the cushion 22. A second air compression cylinder 56 is installed at each position of the fixed shell 55 corresponding to the second gear 57. A second piston rod 58 is slidably connected to one end of the second air compression cylinder 56. A rack 59 is installed on the second piston rod 58. The rack 59 meshes with the second gear 57. An air pipe 53 is installed on the second air compression cylinder 56. By inflating through the air pipe 53, the second piston rod 58 can be driven to expand and contract, thereby facilitating the driving of the rack 59 to move and facilitating the driving of the mounting disk 7 to rotate.

[0046] In the present invention, an air pumping assembly 52 is connected to the support frame 1. The air pumping assembly 52 includes a first air compression cylinder 521.

The free end of the air pipe 53 is installed on the first air compression cylinder 521, and the air pipe 53 is communicated with the first air compression cylinder 521, thereby facilitating the air pumping of the air pipe 53.

[0047] Embodiment 3:

[0048] On the basis of Embodiment 2, a hip bridge training device, a pair of pedals 21 are rotatably connected to one end of the support frame 1. A multi-section lever 28 is connected to the end of the support frame 1 close to the pedals 21. One end of the pedal 21 is connected to the multi-section lever 28. One end of the rotating bar 26 is rotatably connected to a push rod 27. The multi-section lever 28 is hinged to the push rod 27, thereby driving the pedal 21 to rotate. A protection mechanism 3 is connected to the pedal 21. The protection mechanism 3 includes a fixed frame 31. A through "C"-shaped fixed frame 31 is installed on the pedal 21. The open end of the fixed frame 31 faces the cushion 22. A protection plate 33 is rotatably connected to the back side of the pedal 21. One end of the protection plate 33 slidably penetrates through the fixed frame 31. The protection plate 33 is arc-shaped. After the protection plate 33 extends out, it can wrap the feet, thereby preventing the feet from slipping.

[0049] In the present invention, a gear segment 37 is installed on the arc-shaped outer edge of the protective plate 33. A rotating rod 34 is rotatably connected to the pedal 21. A first gear 36 is installed on the rotating rod 34. The first gear 36 meshes with the gear segment 37. A first winding reel 35 is installed on the rotating rod 34. A first pulling rope 32 is wound and connected to the first winding reel 35. The free end of the first pulling rope 32 is fixed to the support frame 1. A first spring 38 is installed between the protective plate 33 and the pedal 21, so as to facilitate the automatic retraction and hiding of the protective plate 33 and facilitate the movement of the foot.

[0050] Working principle: When performing a hip bridge exercise, the user lies flat on the cushion 22, and places both feet on a pair of pedals 21. During the exercise, the rotating frame 24 is bound to the waist by a restraint belt. The counterweight rod 23 can be configured with appropriate counterweight blocks. The collar 43 is sleeved on the counterweight rod 23. The hips are lifted, and the shoulders will exert a downward pressure on the cushion 22. The hips pull the rotating frame 24 to rotate upward through the restraint belt. The hips move downward, driving the rotating frame 24 to reset, thereby completing the hip bridge exercise. When the hips pull the rotating frame 24 to rotate upward through the restraint belt, the scroll spring 8 contracts, thereby driving the second winding reel 47 to rotate, so as to wind up the second pulling rope 41. At the same time, the fourth gear 62 is driven to rotate by the fifth gear 63, driving the third gear 61 and the sixth gear 64 to rotate, driving the rotating disc 465 and the sliding disc 464 to rotate. During the exercise, when suddenly exhausted, the hips lose strength and suddenly drop. The rotating frame 24 rotates downward with the hips. Due to the large gravitational potential energy of the counterweight rod 23 and the body, it has a relatively fast speed when rotating downward, so as to quickly pull the second pulling rope 41 through the collar 43. The second winding reel 47 rotates and releases, and the scroll spring 8 expands. The second winding reel 47 drives the fifth gear 63 to rotate. Through the speed change of the fourth gear 62, the third gear 61 and the sixth gear 64, the rotating disc 465 is driven to rotate at a high speed. Under the action of centrifugal force, the balls 468 are thrown outward, the third spring 467 is compressed, and the balls 468 move into the inside of the chute 466. The sliding disc 464 can slide toward the rotating disc 465. In the initial state, the second spring 462 pushes the fork 461 to squeeze the bearing 463. The bearing 463 is a plain bearing. The inner side of the sliding disc 464 abuts against the balls 468. When the balls 468 move into the inside of the chute 466, the fork 461 pushes the sliding disc 464 to move toward the rotating disc 465. The other end of the fork 461 will push the push rod 44 outward, driving the limiting block 48 to insert into the tooth groove of the sixth gear 64, so as to limit the sixth gear 64, limit the rotation of the second winding reel 47, so as to limit the release of the second pulling rope 41, so as to limit the continuous downward rotation of the rotating frame 24 and the counterweight rod 23, and avoid a large rebound force when the rotating frame 24 falls and impacts the support frame 1, so as to avoid causing damage to the waist of the trainer and enable the rotating frame 24 to hang in the air. Pressing the push rod 44 can make the limiting block 48 separate from the sixth gear 64, thereby releasing the limit;

[0051] The trainer lies on the cushion 22, with the neck touching the sponge cover 51. When the buttocks pull the rotating frame 24 to rotate upward through the restraint belt, the rotating frame 24 pushes the pressure rod 25 to move downward, thereby pushing the rotating bar 26 to rotate. When the buttocks return downward, the rotating bar 26 resets. During the swinging process of the rotating bar 26, the first piston rod 522 is continuously pushed and pulled, thereby continuously squeezing the air inside the first air cylinder 521. Under the action of the air pipe 53, the first air cylinder 521 is connected to the second air cylinder 56, thereby continuously pushing and pulling the second piston rod 58, driving the rack 59 and the second gear 57 to rotate reciprocally, thereby driving the mounting disc 7 to rotate. The two abutting balls 54 on the mounting disc 7 continuously swing, realizing the massage of the trainer's neck, thereby reducing the trainer's fatigue;

[0052] During the training process, when the buttocks lift, the rotating frame 24 pushes the pressure rod 25 to move downward, the pressure rod 25 pushes the rotating bar 26 to rotate, the rotating bar 26 pushes the push rod 27, and the push rod 27 pushes the multi-segment lever 28. The multi-segment lever 28 is composed of three levers connected end to end. The two ends of the multi-segment lever 28 are respectively rotated with the push rod 27 and the pedal 21. Therefore, when the push rod 27 is pushed, the multi-segment lever 28 is driven to rotate, causing the pedal 21 to tilt towards the end away from the cushion 22, thereby facilitating the exertion of force. When the pedal 21 tilts, the first pull rope 32 is slack, and the first spring 38 contracts, thereby pulling the protection plate 33 to rotate upward. The protection plate 33 extends out of the fixed frame 31, thereby shielding and wrapping the sole of the foot, preventing the foot from sliding forward, thereby playing a role in anti-slip and limiting. When the protection plate 33 extends out of the fixed frame 31, the gear segment 37 drives the first gear 36 to rotate, thereby driving the rotating rod 34 to rotate, driving the first winding disc 35 to wind up the first pull rope 32. When the buttocks are lowered, the pedal 21 resets upward, and the first pull rope 32 pulls the first winding disc 35 to rotate, thereby driving the rotating rod 34 and the first gear 36 to rotate, thereby driving the protection plate 33 to be retracted under the pedal 21 through the gear segment 37, thereby hiding the protection plate 33 and facilitating the movement of the foot on the pedal 21.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
