Description

Technical Field

[0001] The invention relates to the technical field of yoga balls, in particular to a multifunctional and portable PVC yoga ball. Background Art

[0002] A yoga ball, also known as a fitness ball or yoga exercise ball, is a type of ball used in conjunction with exercise and fitness. Mostly made of soft rubber or PVC, the inflated ball evenly massages the affected area, promoting blood circulation.

[0003] The yoga ball movements are choreographed to target the abdomen, back, waist and other major parts. When practicing, you should coordinate with slow and rhythmic breathing to perform stretching, squeezing and other movements, so that the muscles can be effectively massaged and relaxed, and the effect of burning fat can also be achieved. It is also a way to improve concentration, reduce mental stress, and enhance the endurance of the limbs and spine.

[0004] The surface of the yoga ball is smooth and the curvature of the surface is large. One hand is not enough to pick it up, and both hands need to apply external force to pick up the yoga ball for carrying. At the same time, because the yoga ball has a spherical appearance, the contact area when placed on the ground is too small, which makes it very easy to roll during use. Both hands are needed to hold it steady before exercising, which can easily affect the user's mood. Therefore, a multifunctional and portable PVC yoga ball is proposed. Summary of the Invention

[0039] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0040] The following describes an embodiment of the present invention based on its overall structure.

[0041] A multifunctional portable PVC yoga ball, such as Figure 1-11 As shown, it includes a sphere 100, an elastic component 200 is fixed to the inner wall of the sphere 100, and a stabilizing component 300 extending outward from the sphere 100 is sleeved inside the elastic component 200. A matching notch is opened at the contact position between the outer wall of the sphere 100 and the stabilizing component 300;

[0042] The stabilizing assembly 300 includes an inner cylinder 310 sleeved inside the elastic assembly 200. A transmission chamber 330 is opened at a lower position inside the inner cylinder 310. Four groups of spring frames 360 are fixed to the lateral inner wall of the inner cylinder 310. A spring 361 is installed in each group of spring frames 360. The lateral inner wall of the inner cylinder 310 is located on both sides of the spring frame 360 ​​and is rotatably connected to four groups of driven rods 320. The bottom end of each group of driven rods 320 extends into the transmission chamber 330. The outer wall of the spring 361 is wrapped with a cable 380 extending from the outside of the spring frame 360. The cable 380 is wound around The outer wall of the driven rod 320 extends out of the inner cylinder 310 at its end. The ends of the two sets of cables 380 are fixedly connected by a magnet. The bottom end of the driven rod 320 is located in the transmission cavity 330 and is fixed with a chassis 350. The bottom end of the chassis 350 is fixed with a vortex bar 351. The outer wall of the bottom end of the inner cylinder 310 is provided with four sets of arc bars 340. The inner wall of each set of arc bars 340 is fixed with a follower bar 341 extending into the interior of the transmission cavity 330. The upper surface of the follower bar 341 contacts the vortex bar 351, and the contact position between the follower bar 341 and the vortex bar 351 is provided with a matching vortex pattern.

[0043] The inner wall of the inner cylinder 310 is located above the clockwork frame 360 ​​and is fixed with an inflatable assembly 370. The inflatable assembly 370 includes a bearing plate 371 fixed to the inner wall of the inner cylinder 310. Two sets of piston frames 372 are fixed to the upper surface of the bearing plate 371. The piston frames 372 are internally sleeved with pistons 378. A piston rod 373 extending from the outside of the piston frame 372 is fixed to one side of the piston 378. The upper surface of the bearing plate 371 is located below the end of the piston rod 373 and is rotatably provided with a top plate. 375. A connecting rod is provided at the bottom end of the top plate 375, which passes through the bearing plate 371 and is fixed to the top end of the driven rod 320. A companion column 376 is fixed to the top of the top plate 375, away from the center. A transverse frame 374 is sleeved on the outer wall of the companion column 376. The side wall of the transverse frame 374 is fixed to the end of the piston rod 373. A telescopic tube 377 is provided on the upper surface of the piston frame 372, which extends to the top end of the accommodating cylinder 250. An air inlet pipe 379 is connected to the lower surface of the piston frame 372.

[0044] The elastic component 200 includes a accommodating tube 250 fixed to the inner wall of the sphere 100, the accommodating tube 250 is sleeved on the outer wall of the inner tube 310, an arc top 210 is provided above the accommodating tube 250, a support ring 240 is fixed to the outer wall of the accommodating tube 250, and a plurality of groups of external elastic strips 220 connected to the bottom end of the arc top 210 are fixed to the top of the support ring 240, and a plurality of groups of internal elastic strips 230 connected to the bottom end of the arc top 210 are fixed to the top of the accommodating tube 250.

[0045] Pull the two pairs of cables 380 out of the inner tube 310 in opposite directions, and pull them upward to fit the outer wall of the sphere 100. Finally, they are fixed by magnetic blocks so that the cables 380 are wrapped around the outer wall of the sphere 100, making it easier to carry the sphere by applying external force.

[0046] As the cable 380 extends, it compresses the mainspring 361 and generates pressure, providing power for the subsequent contraction of the cable 380. As the cable 380 extends, the driven rod 320 rotates synchronously, and the chassis 350 and the vortex bar 351 at its end rotate synchronously accordingly. The rotation trend of the vortex bar 351 follows the inward movement of the follower bar 341, and the arc bar 340 at the end is dragged until it contacts the outer wall of the inner tube 310. At the same time, the four groups of arc bars 340 contract inward synchronously, and then the inner tube 310 can be pushed into the accommodating tube 250, completing the contraction process. This can reduce the space occupied by the yoga ball and provide a gripping pad for the hand, making it easier for the user to carry it.

[0047] On the contrary, the two pairs of cables 380 are released, and the cables 380 are retracted under the action of the spring 361, while the four groups of arc bars 340 are synchronously opened outward and cooperate with the inner tube 310 to increase the contact area with the ground, ensuring that the ball 100 does not roll easily, which is conducive to the user completing fitness exercises with the cooperation of the ball 100;

[0048] As the driven rod 320 rotates, the top plate 375 at the top rotates accordingly. The accompanying column 376 at the upper end of the top plate 375 moves in a circular trajectory. The accompanying column 376 moves in the horizontal frame 374 and generates a back-and-forth squeezing force, causing the horizontal frame 374 to move back and forth and pushing the piston rod 373 and the piston 378 to move. The piston 378 pushes the air inside the piston frame 372 into the sphere 100 to replenish the internal air pressure. When the piston 378 moves in the opposite direction, the air inside the inner cylinder 310 is extracted into the piston frame 372, thereby inflating the sphere 100. If the air pressure is too high, the pressure relief plug 101 can be rotated to exhaust and release the pressure, so that the air pressure in the sphere 100 is at an appropriate state.

[0049] When a user sits on the outside of the sphere 100, the sphere 100 is deformed and the inner wall contacts the arc top 210, and the outer elastic strip 220 and the inner elastic strip 230 are bent and deformed accordingly to resist the external force generated by the deformation, thereby enhancing the elasticity of the sphere 100, better coping with people of different body shapes, and further improving the flexibility of the sphere 100.

[0050] Please refer to Figure 1 and Figure 11 The interior of the sphere 100 is located on one side of the accommodating tube 250 and is provided with a pressure relief plug 101 extending out of the outside of the sphere 100. A hard rubber tube is provided at the contact position between the sphere 100 and the pressure relief plug 101. The pressure relief plug 101 is connected to the hard rubber tube by threads, and the outer wall of the pressure relief plug 101 is provided with an air release channel extending from the end of the sphere 100.

[0051] Rotate the pressure relief plug 101 into the sphere 100, so that its pressure relief channel connects the sphere 100 to the outside world. The air in the sphere 100 can be discharged to the outside, thereby achieving the purpose of exhaust and pressure relief of the sphere 100, ensuring that the sphere 100 is in a suitable state and better assisting fitness exercises.

[0052] Please refer to Figure 5 、 Figure 6 and Figure 7 A guide rod is provided at the inner corner of the corner of the cable 380, and the guide rod is rotatably connected to the transverse inner wall of the inner cylinder 310. An anti-slip wheel 321 is provided at the contact position between the outer wall of the driven rod 320 and the cable 380.

[0053] The guide rod guides and limits the cable 380 , increases the contact area between the outer wall of the cable 380 and the anti-slip wheel 321 , and enables the anti-slip wheel 321 and the driven rod 320 to rotate together while the cable 380 moves.

[0054] A through hole is provided at the contact position between the inner cylinder 310 and the driven rod 320, and the inner part of the through hole and the outer wall of the driven rod 320 are fixed by a bearing.

[0055] The driven rod 320 is provided with a rotation space, and the bearing positions the driven rod 320 and reduces friction resistance;

[0056] A channel connected to the transmission cavity 330 is opened at the contact position between the inner cylinder 310 and the follower bar 341 , and a plurality of air holes connected to the inner cylinder 310 are opened on the inner wall of the top end of the transmission cavity 330 .

[0057] It is convenient for external air to enter through the channel and then enter the inner cylinder 310 through the air hole, providing sufficient air to the piston frame 372.

[0058] Please refer to Figure 3 and Figure 5 A matching cable hole is provided at the position where the outer wall of the inner tube 310 contacts the cable 380 , and an annular groove 311 is provided at a position where the outer wall of the inner tube 310 is flush with the cable hole.

[0059] The cable hole allows the cable 380 to enter and exit, making it convenient to hide and store it. The annular groove 311 can provide the cable 380 with a secure attachment to the outside of the inner tube 310 without affecting fitness exercises.

[0060] Please refer to Figure 9 One-way plates are installed at one end of the telescopic tube 377 and the air intake pipe 379 located in the piston frame 372, and the one-way plates are located inside the ends of the telescopic tube 377 and the air intake pipe 379.

[0061] When the one-way piece at the end of the telescopic tube 377 is opened, the one-way piece at the end of the air inlet pipe 379 is closed, and the air inside the piston frame 372 can be introduced into the sphere 100 through the telescopic tube 377. Conversely, the air in the inner tube 310 can be introduced through the air inlet pipe 379.

[0062] Please refer to Figure 6 、 Figure 7 and Figure 8 Four groups of trapezoidal bars 312 are slidingly provided at the upper position of the outer wall of the inner cylinder 310, and springs 313 are fixed to the ends of the trapezoidal bars 312 of the inner cylinder 310. Four groups of guide grooves 251 are opened on the inner wall of the accommodating cylinder 250, and rubber strips 252 are fixed to the upper part of the left and right inner walls of the guide grooves 251. A fixed ladder block 254 is fixed to the lower part of the side wall of the guide groove 251, and a movable ladder block 253 is provided below the fixed ladder block 254, which is slidably connected to the guide groove 251 through a slider, and a return spring is fixed between the movable ladder block 253 and the guide groove 251.

[0063] When the inner cylinder 310 is pulled downward, the trapezoidal bar 312 on the outer wall contacts the movable ladder block 253. The movable ladder block 253 hinders the trapezoidal bar 312 and makes it move toward the side of the inner cylinder 310 and compresses the spring 313. The end of the trapezoidal bar 312 slides along the end of the movable ladder block 253 until it separates and recovers under the action of the spring 313. Then, the inner cylinder 310 is pushed upward. The trapezoidal bar 312 contacts the movable ladder block 253 and lifts the movable ladder block 253 together. When the movable ladder block 253 contacts the fixed ladder block 254, the inner cylinder 310 is pushed upward continuously. The end of the trapezoidal bar 312 slides along the inclined surface of the movable ladder block 253 and gradually retracts into the inner cylinder 310. Finally, the movable ladder block 253 is moved upward along the movable ladder block 254. The end of the movable ladder block 253 slides until it slides with the end of the fixed ladder block 254, and the movable ladder block 253 is restored under the action of the return spring. Finally, the trapezoidal bar 312 is separated from the fixed ladder block 254 and restored again under the action of the spring 313, continuing to push the inner cylinder 310 upward. The trapezoidal bar 312 slides along the guide groove 251 and contacts the two sets of rubber strips 252, squeezing the rubber strips 252 to deform and slide along the outer wall of the rubber strips 252 after separation. The rubber strips 252 are restored, and the external force applied to the inner cylinder 310 is removed. The inner cylinder 310 slides downward under the gravity of the inner cylinder 310, and the rubber strips 252 limit the trapezoidal bar 312, thereby fixing the inner cylinder 310 in the accommodating cylinder 250.

[0064] When the inner cylinder 310 is pulled out, the inner cylinder 310 is pulled vertically downward, and the trapezoidal bars 312 come into contact with the two sets of rubber bars 252, squeezing the rubber bars 252 to deform and slide along the outer walls of the rubber bars 252 to separate. The inner cylinder 310 is continued to be pulled down, and when it comes into contact with the fixed ladder block 254, the fixed ladder block 254 hinders the trapezoidal bars 312 from moving toward the side of the inner cylinder 310 and compresses the spring 313. The end of the trapezoidal bar 312 slides along the end of the fixed ladder block 254 until it separates, and then recovers under the action of the spring 313, and then the inner cylinder 310 is pulled out. The fixed ladder block 254 prevents the trapezoidal bar 312 from sliding upward, so that the inner cylinder 310 is stabilized in the stretched state, so that fitness exercises can be performed.

[0065] When in use, the two pairs of cables 380 are pulled out of the inner tube 310 in opposite directions, and pulled upward to fit the outer wall of the sphere 100. Finally, the cables 380 are fixed by the magnetic block so that they are wrapped around the outer wall of the sphere 100, which makes it easier to carry the sphere by applying external force.

[0066] As the cable 380 extends, it compresses the mainspring 361 and generates pressure, providing power for the subsequent contraction of the cable 380. As the cable 380 extends, the driven rod 320 rotates synchronously, and the chassis 350 and the vortex bar 351 at its end rotate synchronously accordingly. The rotation trend of the vortex bar 351 follows the inward movement of the follower bar 341, and the arc bar 340 at the end is dragged until it contacts the outer wall of the inner tube 310. At the same time, the four groups of arc bars 340 contract inward synchronously, and then the inner tube 310 can be pushed into the accommodating tube 250, completing the contraction process. This can reduce the space occupied by the yoga ball and provide a gripping pad for the hand, making it easier for the user to carry it.

[0067] On the contrary, the two pairs of cables 380 are released, and the cables 380 are retracted under the action of the spring 361, while the four groups of arc bars 340 are synchronously opened outward and cooperate with the inner tube 310 to increase the contact area with the ground, ensuring that the ball 100 does not roll easily, which is conducive to the user completing fitness exercises with the cooperation of the ball 100;

[0068] As the driven rod 320 rotates, the top plate 375 at the top rotates accordingly. The accompanying column 376 at the upper end of the top plate 375 moves in a circular trajectory. The accompanying column 376 moves in the horizontal frame 374 and generates a back-and-forth squeezing force, causing the horizontal frame 374 to move back and forth and pushing the piston rod 373 and the piston 378 to move. The piston 378 pushes the air inside the piston frame 372 into the sphere 100 to replenish the internal air pressure. When the piston 378 moves in the opposite direction, the air inside the inner cylinder 310 is extracted into the piston frame 372, thereby inflating the sphere 100. If the air pressure is too high, the pressure relief plug 101 can be rotated to exhaust and release the pressure, so that the air pressure in the sphere 100 is at an appropriate state.

[0069] When a user sits on the outside of the sphere 100, the sphere 100 is deformed and the inner wall contacts the arc top 210, and the outer elastic strip 220 and the inner elastic strip 230 are bent and deformed accordingly to resist the external force generated by the deformation, thereby enhancing the elasticity of the sphere 100, better coping with people of different body shapes, and further improving the flexibility of the sphere 100.
