[0086] Please refer to Figure 1 and Figure 2 , the turntable adjustment buckle 100 of the first embodiment of the present invention includes a first fastener 1 and a second fastener 2. The first fastener 1 and the second fastener 2 can be assembled with each other, and the second fastener 2 can rotate relative to the first fastener 1.

[0087] Please also refer to Figure 3 and Figure 4 , the first fastener 1 includes a seat body 11, an annular wall 12, a first matching part 13, a receiving space 14, two limiting parts 15 and two first through holes 16.

[0088] The seat body 11 is generally in the shape of a disc and is used to fix or sew on an article, which can be, for example, garment fabric, cuffs, coat hoods, leather goods, plastic shells, protective gear, backpacks, leather bags, safety helmets, raincoats or shoes, etc. The seat body 11 can be slightly curved to completely adhere to the article, but the present invention is not limited thereto.

[0089] The annular wall 12 extends vertically outward from the seat body 11, and its cross-section is in the shape of a circle. The first matching part 13 is arranged inside the annular wall 12, and the receiving space 14 is defined by the annular wall 12 and the first matching part 13. The first matching part 13 has a connecting part 131, two elastic parts 132 and two tooth parts 133. The connecting part 131 is generally in the shape of an H and is arranged inside the annular wall 12, and can be generally in the same plane as the seat body 11 (such as Figure 4 ). The elastic parts 132 are generally in the shape of square sheets and are connected to the connecting part 131 opposite to each other. For example, one side of the elastic part 132 is connected to the connecting part 131, and the other three sides of the elastic part 132 are not connected to the connecting part 131, so that an elastic force can be generated when the elastic part 132 is deformed by force. The tooth parts 133 are respectively arranged on the elastic parts 132 and face the receiving space 14.

[0090] Please refer to Figure 9 as well. Each tooth portion 133 has an adjacent inclined surface 1331 and a stop surface 1332. The inclined surface 1331 and the stop surface 1332 are respectively obliquely intersecting with the surface 1321 of the elastic portion 132. The area of the inclined surface 1331 is larger than that of the stop surface 1332, such that the cross-section of the tooth portion 133 is generally triangular, and the inclination angle of the inclined surface 1331 with respect to the surface 1321 of the elastic portion 132 is smaller than the inclination angle of the stop surface 1332 with respect to the surface 1321 of the elastic portion 132.

[0091] The limiting portion 15 is generally in the shape of an arc-shaped block, extending outward from the inner side of the annular wall 12 corresponding to each other and facing the accommodating space 14, and is spaced apart from the first matching portion 13. Two first through holes 16 are correspondingly formed through the annular wall 12.

[0092] Please refer to Figure 5 and Figure 6 as well. The second fastener 2 includes an operating portion 21, a column body 22, a second matching portion 23 and a second through hole 24.

[0093] The operating portion 21 is generally in the shape of a disc body, and its edge has a plurality of recessed grooves, which can provide frictional force when the user holds the operating portion 21 to rotate, pull up or press it down. The operating portion 21 is correspondingly provided at the top end of the annular wall 12. The column body 22 is generally in the shape of a cylinder, extending outward from the operating portion 21 and located in the accommodating space 14. The second matching portion 23 is provided at the end of the column body 22 and located in the accommodating space 14, and is assembled with the first matching portion 13.

[0094] The second matching portion 23 has a turntable body 231 and a plurality of positioning grooves 232. The turntable body 231 is generally in the shape of a disc body. The plurality of positioning grooves 232 are respectively recessed from the surface of the turntable body 231 and are spaced apart from each other, and are for the tooth portions 133 to be accommodated therein. In this embodiment, the number of the positioning grooves 232 is 8, arranged in a ring or radially spaced apart from each other, but the present invention is not limited thereto. Please refer to Figure 9 as well. Each positioning groove 232 has an opposite pushing surface 2321 and a limiting surface 2322. The pushing surface 2321 and the limiting surface 2322 are respectively obliquely intersecting with the bottom surface 2323 of the positioning groove 232, such that the cross-section of the positioning groove 232 is generally isosceles trapezoidal, and the inclination angle of the limiting surface 2322 with respect to the bottom surface 2323 of the positioning groove 232 is generally equal to the inclination angle of the stop surface 1332 with respect to the bottom surface 2323 of the positioning groove 232. The second through hole 24 is formed through the column body 22, and its through direction is parallel to the radial direction of the column body 22.

[0095] Please refer to Figure 7 , Figure 8 and Figure 9, when the first fastener 1 and the second fastener 2 are assembled with each other, the second matching portion 23 is pushed into the accommodating space 14 within the annular wall 12. At this time, the peripheral edge of the rotating disc body 231 and the top surface of the limiting portion 15 may respectively have corresponding inclined surfaces, such that the second matching portion 23 can slightly press against the limiting portion 15 and slide into the space between the limiting portion 15 and the first matching portion 13, and the two tooth portions 133 are respectively completely received in two of the plurality of positioning grooves 232. At this time, the inclined surface 1331 corresponds to the pushing surface 2321, and the stopping surface 1332 corresponds to the limiting surface 2322 and engages with the limiting surface 2322. Since the distance between the limiting portion 15 and the first matching portion 13 is approximately equal to the thickness of the second matching portion 23 of the second fastener 2, the second matching portion 23 is limited by the limiting portion 15, so that the second fastener 2 cannot be easily separated from the first fastener 1.

[0096] When the two first through holes 16 and the second through hole 24 are in communication, a rope body 3 can be passed through the first through hole 16 and the second through hole 24. At this time, the rope body 3 is not wound around the column body 22 and can move relative to the first fastener 1 and the second fastener 2. When the rope body 3 is to be wound around the column body 22, the second fastener 2 can be operated to rotate relative to the first fastener 1 in the tightening direction R1 (such as Figure 3 ). In the tightening direction R1, since the area of the inclined surface 1331 is larger than the area of the stopping surface 1332, and the pushing surface 2321 does not engage with the inclined surface 1331, the user can apply a little force to make the pushing surface 2321 slide on the inclined surface 1331 and misalign the pushing surface 2321 and the inclined surface 1331. The elastic portion 132 is pressed and deformed until the pushing surface 2321 slides into the next adjacent positioning groove 232, and then the elastic portion 132 rebounds. At this time, the rope body 3 can be wound around the column body 22. When the rope body 3 is to be released from the column body 22, the second fastener 2 can be operated to rotate relative to the first fastener 1 in the release direction R2 (such as Figure 3 ). In the release direction R2, since the stopping surface 1332 engages with the limiting surface 2322, the user must overcome the resistance generated between the engagement of the stopping surface 1332 and the limiting surface 2322. Therefore, a greater force than that in the tightening direction R1 must be applied to misalign the stopping surface 1332 and the limiting surface 2322. The elastic portion 132 is pressed and deformed until the stopping surface 1332 slides into the next adjacent positioning groove 232, and then the elastic portion 132 rebounds. At this time, the rope body 3 can be released from the column body 22.

[0097] In other words, the engaging strength between the first engaging portion 13 and the second engaging portion 23 varies according to the fastening direction R1 and the releasing direction R2. When the second fastener 2 rotates relative to the first fastener 1 to wind the rope body 3 around the column 22 along the fastening direction R1, the pushing surface 2321 does not engage with the inclined surface 1331, resulting in a relatively small engaging strength between the first engaging portion 13 and the second engaging portion 23, making the user feel that the tightening force of the rope body 3 is relatively light and easy to tighten, so as to avoid an increase in the tension amount of the rope body 3 and a gradually heavier operating feeling. When the second fastener 2 rotates relative to the first fastener 1 to release the rope body 3 from the column 22 along the releasing direction R2, the stopping surface 1332 engages with the limiting surface 2322, resulting in a relatively large engaging strength between the first engaging portion 13 and the second engaging portion 23, making the user feel that the releasing force of the rope body 3 is relatively heavy and increasing the holding force of the rope body 3. That is to say, the engaging strength in the fastening direction is less than the engaging strength in the releasing direction. Therefore, the engaging strength between the first engaging portion 13 and the second engaging portion 23 can provide different operating feelings for the user.

[0098] In this embodiment, the materials of the first fastener 1 and the second fastener 2 are nylon. The first fastener 1 is integrally formed, and the second fastener 2 is integrally formed. However, the present invention is not limited thereto.

[0099] In one embodiment, as Figure 10 and Figure 11 shown, the material of the seat body 11 can be nylon, and the materials of the annular wall 12, the limiting portion 15, and the first engaging portion 13 can be polyoxymethylene and integrally formed. At this time, the seat body 11 has a mounting opening 111, and the annular wall 12 has a convex block 121. The convex block 121 can be snapped into the mounting opening 111 to connect the seat body 11 to the annular wall 12. The purpose of using polyoxymethylene for the material is to prevent the problem that the size will change after contacting water.

[0100] In another embodiment, as Figure 12 and Figure 13 shown, the materials of the seat body 11, the annular wall 12, and the limiting portion 15 are nylon and integrally formed, and the material of the first engaging portion 13 is polyoxymethylene. At this time, the elastic portion 132 is connected to the connecting portion 131 to jointly form a cross shape, and the connecting portion 131 is clamped in the mounting opening 122 of the annular wall 12 to fix the first engaging portion 13 inside the annular wall 12.

[0101] In summary, through the design of the elastic portion, the tooth portion, and the positioning groove of the turntable adjusting buckle of the present invention, the elastic portion deforms under force and generates a resistance against rotation, and the engaging strengths of the tooth portion and the positioning groove in different rotation directions are different, which can provide different operating feelings for the user to intuitively identify the direction of tightening or loosening the rope body. In addition, the turntable adjusting buckle of the present invention has a low number of components, low manufacturing cost, and wide application range.

[0102] Please refer to Figure 14 andFigure 15 , the turntable adjustment buckle 200 of the second embodiment of the present invention includes a first fastener 4 and a second fastener 5. The first fastener 4 and the second fastener 5 can be assembled with each other, and the second fastener 5 can rotate relative to the first fastener 4.

[0103] Please refer to Figure 16 simultaneously. The first fastener 4 includes a seat body 41, an annular wall 42, a first matching portion 43, an accommodating space 44, a first limiting portion 45, and two first through holes 46.

[0104] The seat body 41 is generally in the shape of a rectangular plate and has a shaft hole 411. The seat body 41 is used to be fixed or sewn on an article, and the article can be, for example, garment fabric, cuffs, coat hoods, leather goods, plastic shells, protective gear, backpacks, leather bags, safety helmets, raincoats, or shoes, etc., but the present invention is not limited thereto.

[0105] The annular wall 42 extends vertically outward from the seat body 41, and its cross-section is in the shape of a circular ring. The shaft hole 411 is generally located at the center of the annular wall 42. The accommodating space 44 is defined by the seat body 41 and the annular wall 42. The first matching portion 43 is annularly provided on the annular wall 42 and has a plurality of positioning grooves 431. Each positioning groove 431 has an adjacent pushing surface 4311 and a limiting surface 4312. The pushing surface 4311 and the limiting surface 4312 both face the accommodating space 44. The area of the pushing surface 4311 is larger than the area of the limiting surface 4312, so that the space surrounded by the pushing surface 4311 and the limiting surface 4312 can generally have a triangular cross-section, and the inclination angle of the pushing surface 4311 relative to the inner surface 421 of the annular wall 42 is smaller than the inclination angle of the limiting surface 4312 relative to the inner surface 421 of the annular wall 42. The first limiting portion 45 is generally in the shape of an annular block and extends outward from the top edge of the annular wall 42. The two first through holes 46 are formed through the annular wall 42 corresponding to each other.

[0106] In this embodiment, the number of the positioning grooves 431 is 12, and they are annularly provided on the inner side of the annular wall 42 in such a way that the pushing surface 4311 is adjacent to the next adjacent limiting surface 4312, but the present invention is not limited thereto.

[0107] Please refer to Figure 17 simultaneously. The second fastener 5 includes an operation portion 51, a column body 52, a second matching portion 53, a second limiting portion 54, a second through hole 55, and an assembling column 56.

[0108] The operation part 51 is generally a concave disc body, and its outer edge has a plurality of recessed grooves, which can provide frictional force when the user holds and rotates the operation part 51. The assembly post 56 is arranged at the center of the operation part 51, and the second limiting part 54 is arranged on the inner edge of the operation part 51 and extends inward. When the operation part 51 is correspondingly arranged at the top edge of the annular wall 42, the second limiting part 54 can be buckled to the first limiting part 45. The column body 52 is generally a cylinder, and its two ends respectively have a shaft part 521 and an assembly hole 522. The assembly hole 522 and the assembly post 56 respectively have a square cross-section and can be assembled with each other, so that the column body 52 is erected on the operation part 51 and can move together with the operation part 51. The shaft part 521 is accommodated in the shaft hole 411, so that the second fastener 5 can rotate relative to the first fastener 4 with the shaft part 521 as the axis.

[0109] The second matching part 53 is annularly arranged on the side surface of the column body 52 and matches with the first matching part 43. The second matching part 53 has three claws 530 accommodated in the positioning groove 431. Each claw 530 has a base end 531, a bent body 532 and a buckling body 533. The base end 531 extends outward from the column body 52 (for example, along the radial direction of the column body 52). The bent body 532 is bent and connected to the base end 531 and is spaced from the column body 52, and each bent body 532 extends in the same rotation direction (counterclockwise for Figure 15 and clockwise for Figure 17 ), that is, it is bent along the circumferential direction of the column body 52. The buckling body 533 is arranged at the end of the bent body 532 and faces the positioning groove 431. The buckling body 533 generally has a triangular cross-section and has adjacent inclined surfaces 5331 and stop surfaces 5332. The area of the inclined surface 5331 is larger than the area of the stop surface 5332, so that the inclination angle of the inclined surface 5331 relative to the bent body 532 is smaller than the inclination angle of the stop surface 5332 relative to the bent body 532. The second through hole 55 is formed through the column body 52, and its through direction is parallel to the radial direction of the column body 52.

[0110] Please refer to Figure 18 and Figure 19 ( Figure 19 is a top view after omitting the drawing of the operation part 51 and arranging the second matching part 53 in the seat body 41). When the first fastener 4 and the second fastener 5 are assembled with each other, the shaft part 521 is accommodated in the shaft hole 411, the assembly post 56 is assembled in the assembly hole 522, the first limiting part 45 and the second limiting part 54 are buckled to each other, the first matching part 43 and the second matching part 53 are matched with each other, and the buckling body 533 is accommodated in the positioning groove 431, so that the pushing surface 4311 is correspondingly engaged with the inclined surface 5331, and the limiting surface 4312 is correspondingly engaged with the stop surface 5332.

[0111] When the two first through holes 46 and the second through hole 55 are in communication, a rope body 3 can be passed through the first through hole 46 and the second through hole 55. At this time, the rope body 3 is not wound around the column body 52 and can move relative to the first fastener 4 and the second fastener 5. When the rope body 3 is to be wound around the column body 52, the second fastener 5 can be operated to rotate relative to the first fastener 4 in the fastening direction R1 (such as Figure 19 )). In the fastening direction R1, since the area of the inclined surface 5331 is larger than the area of the stop surface 5332, and the area of the pushing surface 4311 is larger than the area of the limiting surface 4312, that is, the inclination angle of the inclined surface 5331 with respect to the bending body 532 is smaller than the inclination angle of the stop surface 5332 with respect to the bending body 532, and the inclination angle of the pushing surface 4311 with respect to the inner surface 421 of the ring wall 42 is smaller than the inclination angle of the limiting surface 4312 with respect to the inner surface 421 of the ring wall 42. Therefore, the user can apply a little force to make the pushing surface 4311 slide on the inclined surface 5331 and be misaligned with the inclined surface 5331, and the stop surface 5332 moves away from the limiting surface 4312. The bending body 532 is deformed by force and elastically compressed toward the column body 52 until the buckle body 533 slides into the next adjacent positioning groove 431 through the inclined surface 5331 and the pushing surface 4311 and then rebounds. At this time, the rope body 3 can be wound around the column body 52. When the rope body 3 is to be released from the column body 52, the second fastener 5 can be operated to rotate relative to the first fastener 4 in the release direction R2 (such as Figure 19 ). In the release direction R2, since the inclination angle of the stop surface 5332 with respect to the bending body 532 is larger than the inclination angle of the inclined surface 5331 with respect to the bending body 532, and the inclination angle of the limiting surface 4312 with respect to the inner surface 421 of the ring wall 42 is larger than the inclination angle of the pushing surface 4311 with respect to the inner surface 421 of the ring wall 42, and the stop surface 5332 engages the limiting surface 4312, the user must overcome the resistance generated between the stop surface 5332 and the limiting surface 4312. Therefore, a greater force than in the fastening direction R1 must be applied to make the limiting surface 4312 slide on the stop surface 5332 and be misaligned with the stop surface 5332. The bending body 532 is deformed by force and elastically compressed toward the column body 52 until the buckle body 533 slides into the next adjacent positioning groove 431 through the limiting surface 4312 and the stop surface 5332 and then rebounds. At this time, the rope body 3 can be released from the column body 52.

[0112] In other words, the engagement strength between the first engaging portion 43 and the second engaging portion 53 varies according to the fastening direction R1 and the release direction R2. When the second fastener 5 rotates relative to the first fastener 4 to wind the rope body 3 around the column body 52 along the fastening direction R1, the direction in which each bent body 532 extends outward from the base end 531 is opposite to the fastening direction R1. The inclination angle of the inclined surface 5331 with respect to the bent body 532 is smaller than the inclination angle of the stopper surface 5332 with respect to the bent body 532, and the inclination angle of the pushing surface 4311 with respect to the inner surface 421 of the ring wall 42 is smaller than the inclination angle of the limiting surface 4312 with respect to the inner surface 421 of the ring wall 42, which will result in a smaller engagement strength between the first engaging portion 43 and the second engaging portion 53, making the user feel that the tightening force of the rope body 3 is lighter and easier to tighten, so as to avoid an increase in the tightening amount of the rope body 3 and a gradually heavier operating feeling. When the second fastener 5 rotates relative to the first fastener 4 to release the rope body 3 from the column body 52 along the release direction R2, the direction in which each bent body 532 extends outward from the base end 531 is the same as the release direction R2. The inclination angle of the stopper surface 5332 with respect to the bent body 532 is greater than the inclination angle of the inclined surface 5331 with respect to the bent body 532, and the inclination angle of the limiting surface 4312 with respect to the inner surface 421 of the ring wall 42 is greater than the inclination angle of the pushing surface 4311 with respect to the inner surface 421 of the ring wall 42, which will result in a greater engagement strength between the first engaging portion 43 and the second engaging portion 53, making the user feel that the release force of the rope body 3 is heavier and increasing the holding force of the rope body 3. That is to say, the engagement strength in the fastening direction R1 is less than the engagement strength in the release direction R2. Therefore, the engagement strength between the first engaging portion 43 and the second engaging portion 53 can provide the user with different operating feels.

[0113] In this embodiment, the material of the operating portion 51 is nylon, the material of the first fastener 4 is nylon, and the materials of the second engaging portion 53 and the column body 52 are polyoxymethylene, but the present invention is not limited thereto.

[0114] In summary, through the design of the claw and the positioning groove, the claw of the turntable adjusting buckle of the present invention deforms under force and generates a resistance against rotation, and the engagement strength of the claw and the positioning groove is different in different rotation directions, which can provide the user with different operating feels to intuitively identify the direction of tightening or loosening the rope body. In addition, the turntable adjusting buckle of the present invention has a low number of components, a low manufacturing cost, and a wide application range.
