Description
- The present invention relates to an exercising device and, more particularly, to a rotation (or gyration) exercising ball structure that swings smoothly.
- A conventional rotation structure was disclosed in the
U.S. Publication No. 20220193478 , and comprises amain body 10, twobearings 34 mounted in themain body 10, amandrel 30 mounted between the twobearings 34, arotation member 32 having a first end connected with themandrel 30, and a weight 36 mounted on a second end of therotation member 32. Themain body 10 includes twoshells main body 10 has an exterior provided with twooperation portions 14. Themain body 10 has an interior provided with areceiving chamber 22 and two mounting recesses 24. The weight 36 is rotatable in thereceiving chamber 22. The twobearings 34 are mounted in the two mounting recesses 24. In operation, the user's two hands hold and move the twooperation portions 14 so that themain body 10 is rotated, and therotation member 32 and the weight 36 are pivoted about themandrel 30 to produce a centrifugal force. At this time, the twooperation portions 14 function as a pivot fulcrum. In such a manner, the user's two hands have to overcome the centrifugal force produced by the weight 36 so as to achieve an exercising effect. - However, the conventional rotation structure has the following disadvantages.
- 1. The two
bearings 34 are mounted in the two mounting recesses 24 respectively and apply a force on the two mounting recesses 24 so that after themain body 10 is rotated is operated during a period of time, the two mounting recesses 24 are easily cracked or broken, and the twobearings 34 will be dropped. - 2. The
main body 10 is formed by the twoshells shells main body 10 is easily deformed or broken from the connection of the twoshells - 3. The rotation structure cannot provide a corresponding information, such as the time interval, the swinging times, the consumed calories or the like, during rotation of the
main body 10, thereby causing inconvenience to the user when wishing to understand the corresponding information. - 4. A T-shaped construction is defined between the
mandrel 30 and therotation member 32, and themandrel 30 is rotated with its two ends served as fulcrums. In such a manner, the two ends of themandrel 30 and the weight 36 form a triangular structure, so that when a force is applied on themain body 10, the force has to swing themandrel 30, therotation member 32, and the weight 36. Thus, themandrel 30 applies a larger resistance so that the user cannot swing themain body 10 smoothly. - 5. The two ends of the
mandrel 30 are disposed in the twoshells shells mandrel 30, the twobearings 34, and the two mounting recesses 24 are not located at the same central line, so that themandrel 30 is not rotated smoothly. - 6. The manufacturer has to assemble the two
shells mandrel 30, the twobearings 34, and the two mounting recesses 24 at the same central line, thereby prolonging the time of assembly, and thereby increasing the cost. - 7. The conventional rotation structure has many parts with complicated procedures of assembly, thereby increasing the cost of fabrication and production.

hollow ball 1 is mounted on abase 80. - In the preferred embodiment of the present invention, each of the two
shells 10 is made of plastic material. - In the preferred embodiment of the present invention, the outer side of each of the two holding
members 30 is made of silicone or silica gel. - In the preferred embodiment of the present invention, the
weight 44 made of iron has a determined weight and has a radial curved shape. - In the preferred embodiment of the present invention, the second end of the at least one
rotation member 43 is located at an eccentric position of theweight 44 as shown inFIG. 5 . Alternatively, the second end of the at least onerotation member 43 is located at a middle or central position of theweight 44 as shown inFIG. 11 . - In the preferred embodiment of the present invention, the at least one
rotation member 43 is a bending rod and has a bent section secured on themandrel 41 and two distal ends secured to theweight 44. - In the preferred embodiment of the present invention, the
perforation 21 is located at a center of each of the twopivot seats 20. - In operation, referring to
FIG. 12 with reference toFIGS. 1-10 , a user's two hands hold the two holdingmembers 30 to rotate thehollow ball 1. At this time, the linear distance between the user's two palms is served as a fulcrum of the revolving shaft. In such a manner, when thehollow ball 1 is rotated, theweight 44 is revolved in thehollow ball 1 and produces a centrifugal force so that the user has to apply a resistant force to counteract the centrifugal force, thereby achieving an exercising effect. At the same time, when themandrel 41 is rotated, the twomagnets 46 are also rotated with themandrel 41. Thus, when the twomagnets 46 are rotated, theHall sensor 54 detects information (or data) during rotation of the twomagnets 46 and sends the information of rotation of the twomagnets 46 to theBluetooth transmission device 53. Finally, theBluetooth transmission device 53 wirelessly transmits the information to an external portable electronic device, such as a smart phone or a tablet computer. - Alternatively, the
Bluetooth transmission device 53 includes a chargeable lithium battery. Thus, when theBluetooth transmission device 53 and theHall sensor 54 lose power, an adapter, such as a USB connector or the like, in turn extends through theentrance 32 of one of the two holdingmembers 30 and thepassage 511 of thefirst housing 51, and is inserted into thetransmission slot 531 of theBluetooth transmission device 53 to charge theBluetooth transmission device 53 and theHall sensor 54. - Accordingly, the rotation exercising ball structure has the following advantages.
- 1. The
bearings 42 are pivotally mounted on the two ends of themandrel 41 so that themandrel 41 is rotated quietly to prevent from producing noise during rotation. Thus, the user can exercise at any time. - 2. Each of the two
shells 10 is provided with the second reinforcingribs 18 to increase the structural strength of thehollow ball 1 when the twoshells 10 are combined, so that thehollow ball 1 will not be worn or broken after falling. - 3. When the two
shells 10 are combined, the two holdingmembers 30 cover the fixing holes 12 of the twoshells 10 respectively so that thescrews hollow ball 1. - 4. After the two
shells 10 are combined, the two ends of themandrel 41 mounted on the mounting faces 22 of theperforations 21 of the twopivot seats 20 by thebearings 42, and the twopivot seats 20 are secured to the positioning seats 13 of the twoshells 10 and located in the receiving recesses 16 of the twoshells 10. In addition, each of the twoshells 10 is provided with the first reinforcingribs 17 located between the receivingrecess 16 and each of the twoshells 10. Thus, themandrel 41 is rotated steadily and stably, while the at least onerotation member 43 and theweight 44 swing quickly and successively without producing deflection. Further, themandrel 41, the at least onerotation member 43, and theweight 44 are operated smoothly and will not be worn easily to enhance the lifetime. - 5. The
weight 44 made of iron has a determined weight and has a radial curved shape so that theweight 44 radially drives and rotates the at least onerotation member 43 easily. In addition, when a force is applied to radially rotate the at least onerotation member 43 successively, theweight 44 produce an enlarged centrifugal force. It is appreciated that, when the length of theweight 44 is a little less than a half of the perimeter of thehollow ball 1, theweight 44 has the optimum centrifugal effect. - 6. The
inner wall 14 of each of the twoshells 10 is provided with the positioning rails 15, and thefirst housing 51 and thesecond housing 52 are inserted into the fixing holes 12 of the twoshells 10 by guidance of the positioning rails 15 of the twoshells 10 respectively so that thefirst housing 51 and thesecond housing 52 are assembled with the twoshells 10 easily and quickly, thereby saving the assembly time. - 7. The
first housing 51 and thesecond housing 52 are secured to the two holdingmembers 30 respectively by thescrews 60, so that when the user rocks thehollow ball 1, thefirst housing 51 and thesecond housing 52 are supported steadily and stably without vibration. - 8. When the two
magnets 46 are rotated with themandrel 41, theHall sensor 54 detects an information, such as the time interval, the swinging times, the consumed calories or the like, during rotation of the twomagnets 46 and sends the information to theBluetooth transmission device 53 which wirelessly transmits the information to an external portable electronic device, such as a smart phone or a tablet computer. - 9. When the electric power supplied to the
Hall sensor 54 and theBluetooth transmission device 53 is exhausted, the USB connector in turn passes through theentrance 32 of one of the two holdingmembers 30 and thepassage 511 of thefirst housing 51, and is inserted into thetransmission slot 531 of theBluetooth transmission device 53 to charge the chargeable lithium battery of theBluetooth transmission device 53. - 10. The
hollow ball 1 is placed on the base 80 when not in use to prevent thehollow ball 1 from rolling freely and to facilitate the user storing thehollow ball 1. - Referring to the drawings and initially to

The twobearings 42 are mounted in the mountinghole 47 of therotation member 43 and rotatably disposed between therotation member 43 and themandrel 41. Therotation member 43 is radially mounted on a central position of themandrel 41 through the mountinghole 47. Theweight 44 connects a second end of therotation member 43 and is located opposite to themandrel 41. Therotation member 43 and theweight 44 are rotated in thehollow ball 1 radially and centrifugally with themandrel 41 served as an axis. The at least oneauxiliary weight 441 is removably mounted on theweight 44. The twomagnets 46 are mounted on therotation member 43. The twomagnets 46 are arranged at a periphery of the mountinghole 47 of therotation member 43. - The
housing 51 is mounted on and combined with the inner side of one of the two holdingmembers 30. Thehousing 51 is inserted into the fixinghole 12 of one of the twoshells 10. TheBluetooth transmission device 53 is mounted in thehousing 51. TheBluetooth transmission device 53 is electrically connected with theHall sensor 54. TheHall sensor 54 is mounted on themandrel 41. TheHall sensor 54 is close to the mountinghole 47 of therotation member 43 and aligns with the twomagnets 46. - In practice, when the
rotation member 43 is rotated, theHall sensor 54 detects rotation of the twomagnets 46 and sends information or data of rotation of the twomagnets 46 to theBluetooth transmission device 53. - The two
handle protecting members 100 are mounted on the twoshells 10 of thehollow ball 1 respectively and align with the two holdingmembers 30 respectively. - In the preferred embodiment of the present invention, the
hollow ball 1 is mounted on and supported by abase 80. In addition, multiple first reinforcingribs 17 are formed between one of the twopivot seats 20 and one of the twoshells 10, and multiple second reinforcingribs 18 are formed between one of the twopivot seats 20 and thepivot pillar 22. - In the preferred embodiment of the present invention, each of the two holding
members 30 is provided with anelastic locking snap 33 and alocking block 34. Theelastic locking snap 33 and the lockingblock 34 are locked in the fixinghole 12 of one of the twoshells 10. - In the preferred embodiment of the present invention, the at least one
auxiliary weight 441 is locked onto and combined with a bottom or a top of theweight 44 by screws. - In the preferred embodiment of the present invention, each of the two
shells 10 of thehollow ball 1 is provided with at least one connectinghole 101 located adjacent to one of the two holdingmembers 30, and each of the twohandle protecting members 100 is secured on the at least one connectinghole 101 of one of the twoshells 10. - In the preferred embodiment of the present invention, each of the two ends of the
mandrel 41 initially extends through the throughhole 21 of one of the twopivot seats 20, and then one of twonuts 45 is screwed onto each of the two ends of themandrel 41 and locked onto one of the twopivot seats 20, so that each of the two ends of themandrel 41 is secured in the throughhole 21 of one of the twopivot seats 20. - In the preferred embodiment of the present invention, each of the two
bearings 42 is a rolling bearing or a sliding bearing. - In operation, a user's two hands hold the outer sides of the two holding
members 30 to rotate and swing thehollow ball 1 reciprocally. At this time, the linear distance between the user's two palms is served as a fulcrum of the revolving shaft. In such a manner, when thehollow ball 1 is rotated, theweight 44 is revolved in thehollow ball 1 and produces an inertia centrifugal force (or a non-linear inertia G force) so that the user has to apply a resistant force to counteract the centrifugal force, thereby achieving an exercising effect. - The most important feature is in that, the
mandrel 41 is fixed without rotation, and therotation member 43 is rotated about themandrel 41 radially and centrifugally. At the same time, when therotation member 43 is rotated, the twomagnets 46 arranged on the mountinghole 47 of therotation member 43 are also rotated in concert with therotation member 43. Thus, when the twomagnets 46 are rotated, theHall sensor 54 mounted on themandrel 41 will detect the information (or data) during rotation of the two magnets 46 (or the rotation member 43) and transmits the information to theBluetooth transmission device 53. Finally, theBluetooth transmission device 53 wirelessly transmits the information to an external portable electronic device, such as a smart phone or a tablet computer. - Referring to
FIGS. 20 and21 with reference toFIGS. 13-19 , theweight 44 is provided with multiple receivinggrooves 48. Each of the receivinggrooves 48 transversely penetrates theweight 44. Theweight unit 40 includes multipleauxiliary weights 441 mounted in the receivinggrooves 48. Thus, the number of theauxiliary weights 441 is adjusted according to the user's requirement to increase or decrease the swinging centrifugal force of theweight 44. - Accordingly, the rotation exercising ball structure has the following advantages.
- 1. The two
bearings 42 are mounted in the mountinghole 47 of therotation member 43 so that therotation member 43 is rotated on themandrel 41 quietly without producing sound to prevent from causing noise during rotation. Thus, the user can exercise at any time. - 2. The
mandrel 41 is fixed without rotation, and only therotation member 43 is rotated about themandrel 41 reciprocally, to reduce the resistance when therotation member 43 and theweight 44 are rotated centrifugally, so that the user operates and swings thehollow ball 1 easily and smoothly. - 3. Each of the two ends of the
mandrel 41 is secured in the throughhole 21 of one of the twopivot seats 20 so that themandrel 41 is fixed without rotation. Thus, when the twoshells 10 are assembled, themandrel 41 and the twopivot seats 20 are connected easily and conveniently, without having to align themandrel 41 with the throughhole 21 of each of the twopivot seats 20. - 4. The number of the
auxiliary weights 441 on theweight 44 is adjusted according to the user's requirement to increase or decrease the centrifugal force of theweight 44 during rotation of therotation member 43. - 5. When the
rotation member 43 is rotated, the twomagnets 46 arranged on the mountinghole 47 of therotation member 43 are also rotated with therotation member 43. Then, theHall sensor 54 mounted on themandrel 41 will detect the information during rotation of therotation member 43 and sends the information to theBluetooth transmission device 53 which wirelessly transmits the information to an external portable electronic device. Thus, the information, such as the time interval, the swinging times, the calories consumed by the human body or the like, is transmitted to and recorded by the external portable electronic device. - 6. The rotation exercising ball structure has fewer parts to reduce the cost of fabrication, and is assembled easily and quickly to decrease the expense, time, and manual work in assembly.
- 7. The two
handle protecting members 100 are mounted on the twoshells 10 of thehollow ball 1 respectively and align with the two holdingmembers 30 respectively. Thus, when the user's two hands hold the two holdingmembers 30 and apply a force to rotate and swing thehollow ball 1, the user's two hands are restricted by the twohandle protecting members 100, to prevent thehollow ball 1 from being released from the user's two hands, and to prevent thehollow ball 1 from hurting other people. - The difference between the first embodiment and the second embodiment of the present invention is described as follows.
- In the first embodiment, the
mandrel 41, the at least onerotation member 43, and theweight 44 are rotated simultaneously to produce an inertia centrifugal force. In addition, when themandrel 41 is rotated, the twomagnets 46 are rotated with themandrel 41. Thus, theHall sensor 54 detects rotation of the twomagnets 46 and transmits an information of rotation of the twomagnets 46 and themandrel 41 to theBluetooth transmission device 53. - In the second embodiment, the
mandrel 41 is fixed without rotation, and only therotation member 43 and theweight 44 are rotated simultaneously to produce an inertia centrifugal force. In addition, when therotation member 43 is rotated, the twomagnets 46 arranged on the mountinghole 47 of therotation member 43 are also rotated in concert with therotation member 43. Thus, when the twomagnets 46 are rotated, theHall sensor 54 mounted on themandrel 41 will detect the information during rotation of the twomagnets 46 and transmits the information to theBluetooth transmission device 53. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
