Description

Technical Field

[0001] This invention belongs to the field of fitness equipment technology, specifically referring to a multifunctional pelvic floor muscle trainer. Background Technology

[0002] The pelvic floor muscles are a group of muscles that close off the bottom of the pelvis. Abnormal function of these muscles can lead to problems such as urinary incontinence and pelvic organ prolapse, severely impacting quality of life. Currently, pelvic floor muscle trainers on the market are mainly divided into two categories: one is a simple leg-clamping trainer, which only exercises the inner thigh muscles and cannot directly target the pelvic floor muscles, thus limiting its training effect; the other is a seated trainer, which, although it can reach the pelvic floor muscle area, is mostly a one-piece fixed structure with limited functionality, unable to combine leg training with pelvic floor muscle massage. Summary of the Invention

[0003] The purpose of this invention is to provide a multifunctional pelvic floor muscle trainer that has a simple structure, solves the problems of poor training effect and limited function of existing products, and can realize simultaneous training and massage of the leg and pelvic floor muscles.

[0004] The objective of this invention is achieved as follows: A multifunctional pelvic floor muscle trainer includes a leg clamp assembly and a base assembly. The leg clamp assembly includes a main body, a left rotating arm, a right rotating arm, a left support plate, and a right support plate. The left and right rotating arms are rotatably connected to both sides of the main body, and the left and right support plates are fixedly connected to the ends of the left and right rotating arms, respectively. The main body is provided with a damping assembly for providing resistance to the rotation of the left and right rotating arms. The base assembly includes a base, a load-bearing plate, a left seat plate, and a right seat plate. The base is provided with a connecting part, and the rear end of the main body is provided with a fixing part connected to the connecting part. A mounting seat is fixedly provided on the base, and a rotating cavity is formed between the mounting seat and the base. The load-bearing plate is rotatably connected to the rotating cavity through a rotating shaft provided in its middle. The mounting seat is located above the load-bearing plate and between the left seat plate and the right seat plate. A massage head assembly is provided on the mounting seat, and the top of the massage head assembly is higher than the upper surface of the left seat plate and the right seat plate. The left and right seat plates are slidably connected to the left and right sides of the load-bearing plate, respectively. Each of the left and right seat plates includes a seat plate body, a sliding block movably connected to the bottom of the seat plate body, and a limiting block fixedly connected to the sliding block. A rotating rod is provided at the bottom of the seat plate body, and the rotating rod is rotatably connected to the sliding block, so that the seat plate body can rotate relative to the sliding block. The load-bearing plate has symmetrical sliding holes, and two sliding blocks are respectively slidably disposed in the two sliding holes. The limiting block is located below the load-bearing plate and abuts against the bottom surface of the load-bearing plate. A locking structure for limiting the movement of the limiting block is provided between the limiting block and the load-bearing plate. The locking structure includes an oblong hole on the side of the load-bearing plate, a screw fixed on the limiting block, and a knob. One end of the screw passes through the oblong hole and protrudes from the side of the load-bearing plate. The knob is threadedly connected to one end of the screw and can be locked to the side of the load-bearing plate, thereby locking the limiting block and the load-bearing plate and restricting the sliding of the left and right seat plates. Loosening the knob can release the knob from the side of the load-bearing plate, at which time the left and right seat plates can slide.

[0005] Furthermore, the massage head assembly includes a connector that is detachably connected to the mounting base and a massage head disposed on the connector, the connector being detachably mounted on the mounting base via an elastic snap-fit ​​structure.

[0006] Furthermore, the mounting base has a deformation cavity, and the elastic buckle structure includes an elastic plate and a limiting boss on the surface of the elastic plate. The elastic plate is located in the deformation cavity, and one end of the elastic plate is integrally formed with the mounting base. The other end of the elastic plate is a pressing end. Buckle blocks are formed on both sides of the mounting base, and hook portions that can engage with the buckle blocks are formed on both sides of the connecting base. When the connecting base is installed on the mounting base, the limiting boss abuts against the rear end of the connecting base, and the hook portions engage with the buckle blocks. Pressing the pressing end can cause the elastic plate to bend downward. At this time, the limiting boss disengages from the connecting base, thereby disassembling the connecting base.

[0007] Furthermore, the massage head is either a roller assembly that is rotatably mounted on the connecting seat or an arched protrusion that is fixedly mounted on the top of the connecting seat, and both the arched protrusion and the rollers of the roller assembly are fitted with soft silicone sleeves.

[0008] Furthermore, the limiting block has a polygonal locking groove on its side, and the other end of the screw is fixedly connected to a locking block that matches the shape of the polygonal locking groove, and the locking block is embedded in the polygonal locking groove.

[0009] Furthermore, the sliding block has a first rotating groove, the rotating rod at the bottom of the seat body is located in the first rotating groove, and a first bearing is provided in the first rotating groove. The first bearing is sleeved on the rotating rod. The bottom of the seat body has a first placement groove, and a first torsion spring is provided in the first placement groove. The first torsion spring is U-shaped, and the two arms of the first torsion spring abut against the inner walls on both sides of the first placement groove. Both ends of the first torsion spring are bent into first tentacles. The top of the sliding block has a first arc-shaped groove, and the two first tentacles are located in the first arc-shaped groove and abut against the inner walls on both sides of the first arc-shaped groove. When the seat body rotates relative to the sliding block, the first torsion spring deforms.

[0010] Furthermore, the rotating shaft is located in the middle of the bottom surface of the load-bearing plate, and a second rotating groove is provided at the bottom of the rotating cavity. The rotating shaft is rotatably disposed in the second rotating groove, and a second bearing is provided in the second rotating groove. The second bearing is sleeved on the rotating shaft. A second placement groove is provided in the middle of the bottom surface of the load-bearing plate, and a second torsion spring is provided in the second placement groove. The second torsion spring is U-shaped, and its two arms abut against the inner walls on both sides of the second placement groove. Both ends of the second torsion spring are bent into second tentacles. A second arc-shaped channel is provided in the inner wall of the rotating cavity, and the two second tentacles are located in the second arc-shaped channel and abut against the inner walls on both sides of the second arc-shaped channel. When the load-bearing plate rotates relative to the base, the second torsion spring deforms.

[0011] Furthermore, both ends of the base are integrally formed with support feet, the width of the support feet is greater than the width of the base, and the base is arched.

[0012] The outstanding and beneficial technical effects of this invention compared to the prior art are: This invention belongs to the technical field of fitness equipment, specifically referring to a multifunctional pelvic floor muscle trainer, including a leg clamp assembly and a base assembly. The leg clamp assembly consists of a main body, a left rotating arm, a right rotating arm, a left support plate, and a right support plate. The left and right rotating arms are rotatably connected to both sides of the main body, and the left and right support plates are fixedly connected to the ends of the left and right rotating arms, respectively. The main body is equipped with a damping component to provide resistance to the rotation of the left and right rotating arms. This leg clamp assembly structure is conventional in the market. The base assembly consists of a base, a load-bearing plate, a left seat plate, and a right seat plate. The connecting part on the base is connected to the fixing part at the rear end of the main body, making the leg clamp assembly and the base assembly a whole. A mounting seat is fixedly installed on the base. A rotating cavity is formed between the mounting base and the base. The support plate is rotatably connected to the rotating cavity via a pivot in the middle, allowing the support plate to rotate relative to the base. Since the mounting base is located between the left and right seat plates, the top of the massage head assembly on the mounting base is higher than the upper surfaces of the left and right seat plates. During exercise, the user sits facing the leg clamp assembly, with their buttocks fully resting on the left and right seat plates respectively. After adjusting their body position, the pelvic floor muscles naturally conform to the top of the massage head assembly. When the user performs leg clamping exercises, their legs drive the left and right support plates to pull inward, effectively exercising the inner thighs, glutes, and core muscles. Simultaneously, the leg clamping motion causes the buttocks to naturally sway left and right and move back and forth, creating a relative contact between the pelvic floor muscles and the central massage head. The exercise provides passive massage and contraction training for the pelvic floor muscles, achieving a "two-in-one" effect and significantly improving pelvic floor muscle training efficiency. The left and right seat boards are slidably connected to the left and right sides of the support plate, allowing for flexible adjustment of the distance between them according to the user's hip width and body shape, accommodating users of different sizes from children to adults. The seat body is rotatably connected to the sliding block via a rotating rod at the bottom. During use, the user sits on two independent seat boards with their left and right buttocks respectively. The different angles and amplitudes of rotation produced by the left and right buttocks during leg clamping are independently followed and adapted by the corresponding seat board, ensuring that both sides of the pelvic floor muscles maintain even and close contact with the massage head, achieving balanced training and massage of both sides of the muscles. The sliding block's bottom limit... The design of the block tightly abutting against the bottom surface of the load-bearing plate effectively restricts the vertical movement of the sliding block, greatly improving the stability of the seat structure. It adopts a purely mechanical locking structure consisting of a waist-shaped hole on the side of the load-bearing plate, a screw on the limiting block, and a knob. No tools are needed; simply turning the knob manually allows for quick and easy stepless adjustment and secure locking of the seat position, making operation simple and efficient. After locking, the knob end face is tightly pressed against the side of the load-bearing plate, achieving reliable fixation through static friction. The seat will not accidentally shift during use, ensuring safety and stability during training. Compared to the two main types of pelvic floor muscle trainers currently on the market—one being a simple leg-clamping trainer that only exercises the inner thigh muscles and cannot directly target the pelvic floor muscles, resulting in limited training effects—this design offers a significant advantage.Another type is the seated training device, which, while able to reach the pelvic floor muscles, is mostly a fixed, one-piece structure with limited functionality, unable to simultaneously provide leg training and pelvic floor muscle massage. This invention, however, utilizes the movement of the pelvis and buttocks during leg-clamping exercises to drive continuous relative movement between the pelvic floor muscles and the massage head, achieving an active massage effect that combines training and massage. This allows the pelvic floor muscles to be directly massaged and exercised, significantly improving the training effect and achieving a multi-functional effect. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to specific embodiments: like Figures 1-17 As shown, a multifunctional pelvic floor muscle trainer mainly consists of two parts: a leg clamp assembly and a base assembly.

[0032] The leg clamp assembly includes a main body 1, a left rotating arm 2, a right rotating arm 3, a left support plate 4, and a right support plate 5. The left rotating arm 2 and right rotating arm 3 are rotatably connected to the left and right sides of the main body 1, respectively. The left support plate 4 and right support plate 5 are fixedly connected to the ends of the left rotating arm 2 and right rotating arm 3, respectively, by screws. The inner surfaces of the left support plate 4 and right support plate 5 are both designed with curved surfaces that conform to the curve of the inner thigh and are covered with a silicone cushioning layer to improve comfort. A damping component is installed inside the main body 1. This type of leg clamp with a damping component is common in the market. When the user pulls their legs inward, driving the left support plate 4 and right support plate 5 closer together, they need to overcome the elastic resistance of the damping component, thereby exercising the inner thigh muscles, gluteus maximus, gluteus medius, and other muscle groups.

[0033] The base assembly includes a base 6, a load-bearing plate 7, a left seat plate 8, and a right seat plate 9. The base 6 has an overall arched structure that arches upwards, and both its front and rear ends are integrally formed with outwardly extending support feet 41. The width of the support feet 41 is greater than the width of the main body 1 of the base 6, making the base 6 more stable when placed on the ground and less prone to tipping over.

[0034] The base 6 has a connecting part 10 at its front end, and a fixing part 11 adapted to the connecting part 10 at its rear end. The connecting part 10 and the fixing part 11 can be fixedly connected together by bolts to achieve a fixed connection between the leg clamp assembly and the base assembly. A mounting base 12 is fixedly installed above the middle of the base 6, and a rotating cavity 13 is formed between the mounting base 12 and the base 6. The load-bearing plate 7 is rotatably connected to the rotating cavity 13 through a rotating shaft 49 fixedly installed in the middle of its bottom surface. A second rotating groove 43 is opened at the bottom of the rotating cavity 13, and a second bearing 44 is installed in the second rotating groove 43. The second bearing 44 is sleeved on the rotating shaft 49, so that the load-bearing plate 7 can rotate smoothly.

[0035] A second placement groove 45 is formed in the middle of the bottom surface of the load-bearing plate 7, and a second torsion spring 46 is installed inside the second placement groove 45. The second torsion spring 46 is U-shaped, with its two arms abutting against the inner walls on both sides of the second placement groove 45, and both ends are bent into second tentacles 47. A second arc-shaped channel 48 is formed in the inner wall of the rotating cavity 13, and the two second tentacles 47 are located in the second arc-shaped channel 48 and abut against the inner walls on both sides of the second arc-shaped channel 48. When the load-bearing plate 7 rotates relative to the base 6, the second torsion spring 46 undergoes elastic deformation and generates a restoring force, allowing the load-bearing plate 7 to automatically return to its initial position.

[0036] The left seat plate 8 and the right seat plate 9 are slidably connected to the left and right sides of the load-bearing plate 7, respectively. The left seat plate 8 and the right seat plate 9 have the same structure, both including a seat plate body 15, a sliding block 16, and a limiting block 17. The upper surface of the seat plate body 15 is provided with a concave structure that conforms to the curve of the human buttocks, increasing the contact area with the buttocks and dispersing pressure.

[0037] A rotating rod 18 is fixedly installed at the bottom of the seat body 15, and a first rotating groove 35 is opened at the top of the sliding block 16. The rotating rod 18 is inserted into the first rotating groove 35, and a first bearing 36 is installed in the first rotating groove 35. The first bearing 36 is sleeved on the rotating rod 18, so that the seat body 15 can rotate smoothly relative to the sliding block 16.

[0038] The bottom of the seat body 15 has a first placement groove 37, and a first torsion spring 38 is disposed within the first placement groove 37. The first torsion spring 38 is U-shaped, with its two arms abutting against the inner walls on both sides of the first placement groove 37, and both ends are bent into first antennae 39. The top of the sliding block 16 has a first arc-shaped channel 40, and both first antennae 39 are located within the first arc-shaped channel 40 and abut against the inner walls on both sides of the first arc-shaped channel 40. When the seat body 15 rotates relative to the sliding block 16, the first torsion spring 38 undergoes elastic deformation and generates a restoring force, allowing the seat body 15 to automatically return to its initial position.

[0039] The lower end of the sliding block 16 passes through the sliding hole 19 on the load-bearing plate 7 and is fixedly connected to the limiting block 17. The limiting block 17 is located below the load-bearing plate 7 and abuts against the bottom surface of the load-bearing plate 7 to prevent the sliding block 16 from coming out of the sliding hole 19. Two sliding holes 19 extending in the left and right direction are symmetrically provided on the load-bearing plate 7, so that the sliding block 16 can drive the seat body 15 to slide in the left and right direction.

[0040] A locking structure is provided between the limiting block 17 and the load-bearing plate 7 to restrict the movement of the sliding block 16. The locking structure includes an oblong hole 20 on the side of the load-bearing plate 7, a screw 21, and a knob 22. The limiting block 17 has a polygonal locking groove 33 on the side facing the screw 21. One end of the screw 21 is fixedly connected to a locking block 34 that matches the shape of the polygonal locking groove 33. The locking block 34 is embedded in the polygonal locking groove 33 to prevent the screw 21 from rotating. The other end of the screw 21 passes through the oblong hole 20 and protrudes from the side of the load-bearing plate 7, and is threadedly connected to the knob 22.

[0041] When it is necessary to adjust the distance between the left seat plate 8 and the right seat plate 9, loosen the knob 22 to release the knob 22 from the side of the load-bearing plate 7. At this time, the sliding block 16 can slide left and right along the sliding hole 19, moving the seat plate body 15 to the appropriate position. Then tighten the knob 22 to press the knob 22 against the side of the load-bearing plate 7, and lock the limiting block 17 to the load-bearing plate 7 through friction, thereby fixing the position of the seat plate.

[0042] The mounting base 12 is located between the left seat plate 8 and the right seat plate 9, and a massage head assembly 14 is detachably mounted on the mounting base 12. The massage head assembly 14 includes a connecting base 23 and a massage head 24, and the connecting base 23 is detachably mounted on the mounting base 12 by means of a flexible snap-fit ​​structure.

[0043] The mounting base 12 has a deformation cavity 25 in the middle, and the elastic buckle structure includes an elastic plate 26 and a limiting boss 27. The elastic plate 26 is located in the deformation cavity 25, with its front end integrally formed with the mounting base 12 and its rear end being a free pressing end 28. The limiting boss 27 is integrally formed on the upper surface of the elastic plate 26. Buckle blocks 29 are formed upward on the left and right sides of the mounting base 12, and hook portions 30 that can engage with the buckle blocks 29 extend downward on the left and right sides of the connecting base 23.

[0044] When installing the massage head assembly 14, push the connecting seat 23 into the mounting seat 12 from front to back. The hook portion 30 passes over and engages with the latching block 29. At the same time, the limiting boss 27 abuts against the lower rear surface of the connecting seat 23 to prevent the connecting seat 23 from coming out forward. When disassembling, press down on the pressing end 28 of the elastic plate 26 to bend the elastic plate 26 downward, causing the limiting boss 27 to disengage from the connecting seat 23. Then, pull the connecting seat 23 forward to remove it.

[0045] The massage head 24 has two optional forms: one is a roller assembly mounted on the connecting seat 23, including four symmetrically distributed spherical rollers, which can perform rolling massage on the pelvic floor muscles; the other is an arched protrusion fixed on the top of the connecting seat 23, which can perform pressing massage on the pelvic floor muscles. The outer surfaces of both the rollers of the roller assembly and the arched protrusion are covered with soft silicone sleeves to improve massage comfort.

[0046] Working principle and usage When using, adjust and lock the distance between the left seat 8 and the right seat 9 according to your own hip width. The user sits on the left seat 8 and the right seat 9, so that the left and right buttocks are in contact with the two seat bodies 15 respectively, the pelvic floor muscle area is in contact with the massage head 24 in the middle, and the inner sides of the two thighs are in contact with the left support plate 4 and the right support plate 5 respectively.

[0047] During training, the user forcefully pulls their legs inward, driving the left rotating arm 2 and right rotating arm 3 closer together. This process requires overcoming the resistance of the damping component within the main body 1, thereby exercising the inner thighs, glutes, and core muscles. Simultaneously, the leg-pulling motion causes the hips to naturally sway left and right and move forward and backward, creating relative movement between the pelvic floor muscles and the massage head 24. The massage head 24 then rolls or presses against the pelvic floor muscles, promoting their contraction and relaxation.

[0048] During training, the seat body 15 rotates naturally with the user's body posture, and the weight-bearing plate 7 adapts to the user's left and right tilt angles, ensuring that the pelvic floor muscles maintain optimal contact with the massage head 24 while avoiding uneven stress on the joints. After training, the legs relax, and the left and right rotating arms 2 and 3 automatically open under the action of the damping components. The seat body 15 and the weight-bearing plate 7 automatically return to their original positions under the action of the first torsion spring 38 and the second torsion spring 46, respectively.

[0049] When it is necessary to replace the massage head 24, press the pressing end 28 of the elastic plate 26 to remove the current massage head assembly 14 and replace it with another type of massage head assembly 14.

[0050] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
