The accompanying drawings illustrate one ore more embodiments of the invention and, together with the written description, serve to explain the principles of the invention, and wherein:
By reference to
The hoop body A comprises a plurality of arc-shaped unit sections 1 connected end to end. Two adjacent unit sections 1 are detachably connected to each other through a connecting member 2. The connecting member 2 is an arc-shaped plate structure, and an accommodating groove D for inserting a portion of the connecting member 2 is formed on the unit section 1. The accommodating groove D is arranged on the outer side of the unit section 1 and extends along the length direction of the unit section 1. Specifically, the front portion of the concrete connecting member 2 is inserted into the accommodating groove D of the unit section 1, the rear portion of the connecting member 2 is inserted into the accommodating groove D of another unit section 1. The unit section 1 has a locking mechanism that keeps the connecting member 2 in the accommodating groove D, thereby connecting two adjacent unit sections 1 together, and the inner diameter of the hoop body A is changed by increasing or decreasing the number of the unit sections 1, so as to adapt to exercise with different body shapes.
A first two protruding strips 24 protruding outward and extending along the length direction are formed on both sides of the lower part of the connecting member 2. A reinforcing rib 22 protruding downward and extending along the periphery is formed at the bottom edge of the connecting member 2. The first two protruding strips 24 are arranged on the reinforcing rib 22. A second two protruding strips 112 protruding inward and extending along the length direction are formed on the two opposite groove walls of the accommodating groove D, the second protruding strips 112 press on the upper side of the first protruding strips 24, and the first protruding strips 24 and the second protruding strips 112 cooperate to guide the connecting member 2 to be inserted into the accommodating groove D and restrict the connecting member 2 from laterally coming out of the accommodating groove D. To cover the gap between the components, side edges 23 protruding outward are formed on both sides of the upper part of the connecting member 2.
The connecting member 2 is made of elastically deformable material, specifically plastic with a certain degree of elasticity. There is a gap between two adjacent unit sections 1, and a reinforced deformable structure 21 between the front and rear portions of the connecting member 2 is formed in the gap between two adjacent unit sections 1. The reinforced deformable structure 21 adopts a U-shaped groove structure, which makes two adjacent unit sections 1 bend relatively elastically after being connected to each other, so as to adapt to hoop bodies with different inner diameters. Of course, even without the reinforced deformable structure 21, as the connecting member 2 is made of elastically deformable material, the relative elastic bending of two connected adjacent unit sections 1 can still be realized. In addition, as the connecting member 2 has elasticity, the elastic change of the inner diameter of the hoop body A can be increased, and the reinforced deformation structure 21 can also increase the elastic change.
The specific structure of the unit section 1 includes an arc-shaped outer body 11 and an inner body 12, the outer body 11 is connected to the inner body 12 by screws, and two arc-shaped plates 111 extending along the length direction are formed on both sides of the outer body 11. A first arc-shaped groove is formed between the inner section of the arc-shaped plate 111 and the outer body 11, and the outer section of the two arc-shaped plates 111 forms an accommodating groove D for receiving the connecting member 2, the second protruding strips 112 are formed on the opposite surface of the outer section of the two arc-shaped plates 111, two side edges 121 extending upward are formed on both sides of the inner body 12, and a second arc-shaped groove is formed between the side edge 121 and the inner body 12. The first arc-shaped groove and the second arc-shaped groove are arranged oppositely to form a track groove B extending along the length direction of the unit section 1 and passing through both side surfaces of the unit section 1. The track groove B is a narrowing groove, and the slider 4 has two side plates 41 extending to both sides of the unit section 1. The side plate 41 has a plurality of rollers 43 located in the track groove B, so that the slider 4 can be slidably arranged on the hoop body A, and the counterweight assembly 6 is connected to the slider 4 through the strap 5. When the exerciser twists his/her waist, the slider 4 can be driven to slide and rotate on the hoop body A under the action of the counterweight assembly 6. The counterweight assembly 6 includes a spherical shell and a plurality of counterweights 63 arranged in the shell, and the shell includes a main body 61 and a detachable cover 62.

A supporting portion 122 for supporting the massage protrusions 124 is formed in the mounting groove. A relief hole 1231 for massage protrusions 124 to pass through is formed on the gusset plate 123. The gusset plate 123 is snap-fitted with the mounting groove, and the base plate 125 is pressed into the mounting groove through the gusset plate 123 and the massage protrusions 124 are exposed. The massage protrusions 124 massage the waist of the exercisers, and a magnet 126 is additionally provided in the massage protrusions 124, so that the massage protrusions 124 have a magnetic therapy function.
The locking mechanism includes an operating button 3 and a spring 33. The operating button 3 can be floatably provided on the unit section 1 between the locking position and the releasing position. The specific structure is as follows: the middle of the outer surface of the outer body 11 has a mounting hole 113 for mounting the operating button 3, a first groove 34 for receiving one end of the spring 33 is formed at the bottom of the operating button 3, a second groove 127 for receiving the other end of the spring 33 is formed on the inner body 12, and the spring 33 is arranged between the first groove 34 and the second groove 127 to drive the operating button 3 to reset to the locking position. A plurality of limit hooks 32 are provided on the operating button 3, and the limit hooks 32 are used to restrict the operating button 3 from coming out of the mounting hole 113 from the outside of the outer body 11, the first two limiting portions 31 are provided on opposite sides of the operating button 3, and the second limiting portions 25 are respectively provided at the bottoms of both ends of the connecting member 2, an inclined guiding slope 311 is formed on the front side of the first limiting portions 31, and the second limiting portions 25 can be guided to the rear side of the first limiting portions 31 by the guiding slope 311 when the connecting member 2 is inserted into the accommodating slot D. In this process, the first limiting portions 31 are firstly compressed by the second limiting portions 25 to make the operating button 3 move to the releasing position. When the second limiting portions 25 move to the rear side of the first limiting portions 31, the operating button 3 is reset to the locking position under the action of the spring 33, so that the connecting member 2 cannot come out of the accommodating groove D. When two adjacent unit sections 1 need to be detached, the exercisers only need to press the operating button 3 to move to the releasing position, and then pull out the connecting member 2.
An arc-shaped notch C matching the main body of the operating button 3 is formed at the two ends of the connecting member 2, so that the connecting member 2 services not only as a connecting part of the unit sections 1 to connect two adjacent unit sections 1, but also as a forming part of the outer peripheral surface of the hoop body to make the overall structure more reasonable and compact.
The slider 4 has a counter 42 and a magnetic sensor 43. A certain unit section 1 has a magnet 7 which can be sensed by the magnetic sensor 43. The magnetic sensor 43 is connected to the counter 42, and the counter 42 can obtain the number of moving revolutions and display it according to the detection signal of the magnetic sensor 43. Specifically, the magnet 7 can be arranged in the first groove 34 to facilitate its assembly without the need of providing an installation structure. When the slider 4 rotates around the hoop body once, the magnetic sensor 43 can sense the magnet once, thus accurately counting the number of moving revolutions and displaying it through the counter 42.
The specific exercise method is as follows: Before exercise, the inner diameter of the hoop body A can be adjusted according to the waistline of the exerciser. The inner diameter of the hoop body A can be adjusted by increasing or reducing the number of unit sections 1. The disassembly and assembly of the unit sections 1 is achieved through the combination of the locking mechanism and connecting member 2, which enable quick and convenient disassembly and assembly of the unit sections 1, and the hoop body A can be opened at any position. The rollers 43 of the slider 4 are installed into the track groove B from the end of the unit section 1 at the opening position of the hoop body A, then wrap around the waist of the exerciser and connect the two adjacent unit sections 1 at the opening position of the hoop body A to close the hoop body A. Then, the exerciser twists his/her waist to drive the counterweight assembly 6 to rotate around the waist, thereby driving the slider 4 to rotate around the hoop body A, and the number of revolutions is counted and displayed during the rotation of the slider 4.
