DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(10) Please refer to FIGS. 1 to 2, illustrating a waist training device according to the present invention. The waist training device comprises a ring A and a counter weight member 3. Specifically, a plurality of unit members 1, in arc shaped, is assembled with each other to form the ring A. The inner diameter of the ring A is determined by the number of the unit members 1. In detail, the more the unit members 1, the longer the length of the ring A, and the longer the inner diameter of the ring A. Accordingly, the number of the unit members 1 can be adjusted according to user's waistline, so that the inner diameter of the ring A mates with the waistline of the user, and the ring A can be firmly positioned on the waist. Therefore, the ring A can be adapted to users with different body shapes.

(11) As shown in FIG. 3, each of the unit members 1 has a bottom wall 11 and two sidewalls 12 respectively standing at two sides of the bottom wall 11, so that the unit members 1 are approximately of U-shaped. The two sidewalls 12 are flexible, thus when an external force is applied to the sidewalls 12, the sidewalls 12 would deform slightly with respect to the bottom wall 11. A passage 13 is defined between the two sidewalls 12. When the unit members 1 are assembled with each other, the passages 13 of the unit members 1 are connected with each other to form a rail A1 extended annularly along the ring A (as shown in FIG. 1). Furthermore, two pivot shafts 14 are defined at first ends of the two sidewalls 12 and located at one of two ends of the passage 13, two pivot holes 15 are defined at second ends of the two sidewalls 12 and located at the other end of the passage 13, and the first end is opposite to the second end. A guiding tapered section 16 is formed on each of the sidewalls 12 and near to the corresponding pivot hole 15, and a stopping portion 17 is assembled on each of the sidewalls 12 and atop the corresponding pivot hole 15.

(12) According to the unit member 1 mentioned above, several unit members 1 can be assembled in order to form the ring A. Specifically, as shown in FIG. 4, firstly, one of the pivot shafts 14A of the unit member 1 is inclinedly engaged with one of the pivot holes 25A of the unit member 2, and the other pivot shaft 14B of the unit member 1 is abutted against the corresponding guiding tapered section 26 of the unit member 2. And then, the unit member 1 is rotated using the pivot shaft 14A as the rotating axis, so that the pivot shaft 14B is moved along the guiding tapered section 26 and inserted into the pivot hole 25B. Therefore, two adjacent unit members can be assembled with each other. Based on the above, several unit members can be assembled sequentially in an end-to-end manner to form the ring A.

(13) Conversely, to disassemble the unit member 1 from the unit member 2, as shown in FIG. 5, the unit member 1 is pivotally rotated with respect to the unit member 2, so that the two sidewalls 12 of the unit member 1 are deformed due to the force applied by the two stopping portions 27 of the unit member 2, thereby the two pivot shafts 14 of the unit member 1 are detached from the pivot holes 25 of the unit member 2. Therefore, the unit member 1 can be detached from the unit member 2.

(14) In addition, in this embodiment, one of the unit members is defined as a connecting member. The connecting member has structures which facilitate the connecting member to be assembled with other unit members 1 conveniently, thus facilitating the assembling of the ring A. As shown in FIG. 6, the structure of the connecting member 4 is approximately the same as the structure of the unit member 1, except that two guiding grooves 43 are further defined on the connecting member 4 and respectively correspond to the two pivot holes 42 of the connecting member 4, so that the pivot shafts of one of two adjacent unit members are guided by the guiding grooves 43 of the connecting member 4 and inserted into the pivot holes 42 of the connecting member 4. Two buckling members are further pivoted with the connecting member 4 and respectively correspond to the two pivot holes 42 of the connecting member 4. Each of the buckling members comprises a first buckling block 44 and a second buckling block 45. The first buckling block 44 is pivoted on the sidewall 41 via a first spring 441, and the first buckling block 44 can be inserted into the corresponding guiding groove 43 by means of pivot, so that the first buckling block 44 can be buckled with the corresponding pivot shaft of the adjacent unit member. The second buckling block 45 is pivoted on the sidewall 41 via a second spring 451. The second spring 451 controls the position of the second buckling block 45, so that the second buckling block 45 can be engaged with the first buckling block 44.

(15) Accordingly, as shown in FIG. 7 and FIG. 8, the connecting member 4 is configured as the head and followed by a series of unit members, and one of the pivot shafts 14 of the last unit member 1 in the series is guided by the corresponding guiding groove 43 of the connecting member 4 and inserted into the corresponding pivot hole 42 of the connecting member 4. Next, the first buckling block 44 is rotated so that the first buckling block 44 is inserted into the guiding groove 43 and buckled with the pivot shaft 14. Therefore, the connecting member 4 can be securely connected with the adjacent unit member 1. In addition, when the first buckling block 44 is rotated, the first buckling block 44 also pushes the second buckling block 45 away; while after the first buckling block 44 is buckled with the pivot shaft 14, the second buckling block 45 moves resiliently by the elastic force from the second spring 451, so that the second buckling block 45 engages with the first block 44. Consequently, the connecting member 4 can be firmly connected with the adjacent unit member 1.

(16) The operations of the unit members for forming the ring are described as above. In this embodiment, as shown in FIG. 1, each of the unit members 1 further defines a through hole 18, an elastic band 19 is passing through the through holes 18 of the unit members 1, and two ends of the elastic band 18 are connected to form an elastic ring. The elastic ring is provided to firmly surround the ring A on the waist of a user, facilitating the mating between the ring A and the user's waist and preventing the user's body from being clamped by the unit members 1.

(17) Furthermore, the rail A1 of the ring A further has a counter weight member 3. Specifically, as shown in FIG. 2, the counter weight member 3 comprises a seat 31 and a counter weight block 32. The seat 31 is formed by two slide units 33 pivoted with each other. The two slide units 33 are pivotable with each other. The seat 31 and the counter weight block 32 are connected by a length adjustable rope 34. The seat 31 is slidably assembled on the rail A1. As shown in FIG. 9, the curvature of the rail A1 changes along with the change of number of the unit members 1. Since the two slide units 33 of the seat 31 are pivotable with each other to meet the curvature of the rail A1, the seat 31 can be slidably fitted on the rail A1. Therefore, the seat 31 can be smoothly moved along the rail A1.

(18) In addition, in this embodiment, as shown in FIG. 8, a counter 5 is assembled to the connecting member 4. The counter 5 has a sensing element 51, while the seat 31 has a sensing element 52 corresponding to the counter 5. When the seats 31 meet with the counter 5, the two sensing elements 51, 52 generates a sensing, and the sensing is recorded by the counter 5. Accordingly, the times the counter weight member 3 traveling around the ring A caused by the shaking of the user's waist can be counted. The counter 5 may be a mechanical contact type counter, or may be an optical contactless type counter, embodiments are not limited thereto.

(19) Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
