Abstract
A magnetic fastening buckle includes a male and a female buckle member that can be moved toward and engaged with each other by magnetic attraction between two magnets separately provided thereon; and an anti-separation member movably connected to the male buckle member. When the anti-separation member is located at an unlocking position, it does not overlap the female buckle member, allowing the male buckle member to move rearward in a y-axis direction to separate from the female buckle member. When the anti-separation member is moved in an x-axis direction to a locking position, it can overlap the female buckle member. In this position, the anti-separation member can overlap the female buckle member when the male buckle member is pushed toward a rear removal opening, so as to prevent the male buckle member from separating from the female buckle member, allowing the two buckle members to remain engaged with each other.

Meanwhile, the contact of the slant male-side guiding surfaces 91 with the slant female-side guiding surfaces 92 leads the male buckle member 20 to move leftward in the x-axis direction. Finally, the male buckle member 20 moving downward in the z-axis direction and leftward in the x-axis direction is moved from the contact position P2 to a staggered position P3. As shown, when the male buckle member 20 is located at the staggered position P3, the engagement portion 411 and the retaining protrusions 412 of the retaining means 40 are located in the engaging space 421 of the female-side retaining portion 42. At this point, the male-side magnet 51 is partially located above the female-side magnet 52; and the first and the second center of gravity 511, 521 of the male-side and the female-side magnet 51, 52, respectively, are located on two different vertical straight lines L. That is, the male-side magnet 51 and the female-side magnet 52 are staggered in position.
[0088] Please refer to FIG. 9D. When the male buckle member 20 is moving from the contact position P2 to the staggered position P3 and the male-side guiding surfaces 91 of the guiding means 90 are no longer in contact with the female-side guiding surfaces 92 of the guiding means 90, the male-side magnet 51 on the male buckle member 20 is magnetically attracted by the female-side magnet 52 on the female buckle member 30 to be movable rightward in the x-axis direction, such that the male buckle member 20 is moved from the staggered position P3 to an engaged position P4. At this point, the male-side contact surface 213 of the male buckle member 20 is in contact with the female-side contact surface 313 of the female buckle member 30 and the male-side retaining portion 41 of the retaining means 40 is engaged with the female-side retaining portion 42 of the retaining means 40. In the first preferred embodiment, when the male buckle member 20 is located at the engaged position P4, the retaining protrusions 412 of the male-side retaining portion 41 are received in the retaining space 422 of the female-side retaining portion 42, while the engagement portions 411 of the male-side retaining portion 41 are located in the engaging space 421 of the female-side retaining portion 42. Therefore, the anti-separation block 413 of the male-side retaining portion 41 can extend into the anti-separation space 423 of the female-side retaining portion 42. Meanwhile, the front stop section 62 of the anti-separation member 60 is located outside a front position of the female main body 31 of the female buckle member 30 in the y-axis direction, such that the front stop section 62 and the rear removal opening 425 of the female-side retaining portion 42 is located at a front and a rear side, respectively, of the female main body 31. When the male buckle member 20 is located at the engaged position P4, the male-side magnet 51 and the female-side magnet 52 of the magnetic attraction means 50 are still staggered from each other. As shown in FIG. 2A, when the male buckle member 20 is located at the engaged position P4, since the male-side retaining portion 41 is extended into and engaged with the female-side retaining portion 42, one of the first woven strap 100c and the second woven strap 100d will still stay at a user's chin to prevent the helmet 100a from separating from the user's head. Alternatively, as shown in FIG. 2B, when the male-side retaining portion 41 is engaged with the female-side retaining part 42, the flap cover 100b2 of the backpack 100b is not openable to thereby prevent things held in the things-carrying bag 100b1 from falling off the backpack 100b.
[0089] Please refer to FIGS. 10A to 10C, which depict the manner of separating the male buckle member 20 from the female buckle member 30 of the magnetic fastening buckle 2 according to the first preferred embodiment of the present invention. When the male-side retaining portion 41 of the retaining means 40 is engaged with the female-side retaining portion 42 of the retaining means 40, the anti-separation member 60 is located at an unlocking position SI and the front stop section 62 of the anti-separation member 60 is staggered from the female main body 31 of the female buckle member 30, such that the front stop section 62 does not overlap any part of the female main body 31 of the female buckle member 30. When the anti-separation member 60 is located at the unlocking position S1, the limiting ribs 82 of the limiting mechanism 80 are in contact with the closed ends 811 of the limiting recess 81, and the first locating part 71 of the locating means 70 are connected with one of the two second locating parts 72, such that the anti-separation member 60 is held to the unlocking position S1. As shown in FIGS. 10D and 10E, when a first removal force F1 is applied to the male buckle member 20 in a direction parallel to the y-axis to move the male buckle member 20 in the y-axis direction relative to the female buckle member 30, the retaining protrusions 412 of the male-side retaining portion 41 would be moved toward the rear removal opening 425 of the female-side retaining portion 42. When the retaining protrusions 412 are being moved toward the rear removal opening 425, the anti-separation block 413 of the male-side retaining portion 41 would get into contact with the anti-separation surface 426 of the anti-separation space 423. At this point, in the case the first removal force F1 has a magnitude large enough to drive the male buckle member 20 to separate from the female buckle member 30, the anti-separation block 413 would be moved to the engaging space 421 of the female-side retaining 42 while keep contacting with the anti-separation surface 426, such that the male buckle member 20 is movable relative to the female buckle member 30 in the x-axis and the y-axis direction at the same time. When the retaining protrusions 412 pass over the rear removal opening 425, they are separated from the retaining space 422 of the female-side retaining portion 42, allowing the male buckle member 20 to be removable from the female buckle member 30. At this point, the user may conveniently separate the male buckle member 20 from the female buckle member 30.
[0090] Please refer to FIG. 10F. In the case the first removal force F1 has a magnitude too small to drive the male buckle member 20 to separate from the female buckle member 30, the magnetic attraction force between the male-side magnet 51 and the female-side magnet 52 of the magnetic attraction means 50 enables the anti-separation surface 426 of the anti-separation space 423 to drive the anti-separation block 413 of the male-side retaining portion 41 to move, such that the anti-separation block 413 are moved back into the anti-separation space 423 and it is ensured the retaining protrusions 412 of the male-side retaining portion 41 can be received in the retaining space 422 of the female-side retaining portion 42. In this manner, once the male buckle member 20 is assembled to the female buckle member 30, it is not a concern that whether the male buckle member 20 would separate from the female buckle member 30 due to the first removal force F1. To the contrary, the magnetic fastening buckle 2 can be safer for use.
[0091] Please refer to FIGS. 11A to 11C, which depict the manner of preventing the male buckle member 20 from separating from the female buckle member 30 of the magnetic fastening buckle 2 according to the first preferred embodiment of the present invention. First, the anti-separation member 60 is moved leftward in the x-axis direction from the unlocking position S1 to a locking position S2, so that the anti-separation member 60 is moved across the male buckle member 20 to the female main body 31 of the female buckle member 30 and the front stop section 62 is able to overlap any part of the female main body 31 in the y-axis direction. When the anti-separation member 60 is located at the locking position S2, the limiting rib 82 of the limiting mechanism 80 is extended through the open ends 812 of the limiting recess 81, and the first locating part 71 of the locating means 70 is engaged with another one of the two second locating parts 72, so that the anti-separation member 60 is held to the locking position S2. Then, as shown in FIG. 11D, a first removal force F1 is applied to the male buckle member 20 for the latter to move rearward in the y-axis direction relative to the female buckle member 30. At this point, the front stop section 62 of the anti-separation member 60 gets in contact with the front side of the female main body 31 to prevent the male main body 21 from separating from the female main body 31.
[0092] Please refer to FIG. 12, which shows a magnetic fastening buckle 2 according to a second preferred embodiment of the present invention. The magnetic fastening buckle 2 in the second preferred embodiment includes a male buckle member 20, a female buckle member 30, a set of retaining means 40, a set of magnetic attraction means 50, an anti-separation member 60, a set of locating means 70, a set of limiting mechanism 80, and a set of guiding means 90. The second preferred embodiment is different from the first one in that the female buckle member 30 and the anti-separation member 60 respectively have a structure different from that in the first preferred embodiment. Since the male buckle member 20, the set of retaining means 40, the set of magnetic attraction means 50, the set of locating means 70, the set of limiting mechanism 80, and the set of guiding means 90 have structures the same as those in the first preferred embodiment, they are not repeatedly described herein.
[0093] Please refer to FIGS. 12 and 13. In the second preferred embodiment, the female-side woven strap connection section 312 of the female buckle member 30 has a thickness larger than that of the female-side coupling section 311 of the female main body 31; and one side of the female-side woven strap connection section 312 opposite to the female-side coupling section 311 is protruded to form a limiting block 316, the limiting block has a height position higher than that of the female-side retaining portion 42 of the retaining means 40. In addition, the anti-separation member 60 further includes a front reinforcing stop section 63, which is formed on the front connection plate 612 of the connection section 61, so that the front stop section 62 and the front reinforcing stop section 63 of the anti-separation member 60 are located at the same side of the connection section 61. When the anti-separation member 60 is movably connected to the male buckle member 20, the front reinforcing stop section 63 has a height position higher than the male-side contact surface 213 of the male buckle member 20.
[0094] Please refer to FIGS. 14A and 14B, which depict the manner of separating the male buckle member 20 from the female buckle member 30 according to the second preferred embodiment of the present invention. First, when the male-side retaining portion 41 of the retaining means 40 is engaged with the female-side retaining portion 42 of the retaining means 40, the anti-separation member 60 is located at an unlocking position S1, and neither the front stop section 62 nor the front reinforcing stop section 63 of the anti-separation member 60 overlap any part of the female main body 31. Then, apply a first removal force F1 to the male buckle member 20 for the latter to move in the y-axis direction relative to the female buckle member 30, such that the retaining protrusions 412 of the male-side retaining portion 41 approach the rear removal opening 425 of the female-side retaining portion 42 gradually. When the retaining protrusions 412 are being moved toward the rear removal opening 425, the anti-separation block 413 of the male-side retaining portion 41 would get into contact with the anti-separation surface 426 of the anti-separation space 423. At this point, in the case the first removal force F1 has a magnitude large enough to drive the male buckle member 20 to separate from the female buckle member 30, the anti-separation block 413 would be moved to the engaging space 421 of the female-side retaining portion 42 while keeps contacting with the anti-separation surface 426, such that the male buckle member 20 is movable relative to the female buckle member 30 in the x-axis and the y-axis direction at the same time. When the retaining protrusions 412 pass through the rear removal opening 425, the retaining protrusions 412 are separated from the retaining space 422 of the female-side retaining portion 42, such that the male buckle member 20 is removable from the female buckle 30 and the user can conveniently separate the male buckle member 20 from the female buckle member 30.
[0095] Please refer to FIGS. 15A and 15B, which depict the manner of preventing the male buckle member 20 from separating from the female buckle member 30 according to the second preferred embodiment of the present invention. First, the anti-separation member 60 is moved in the x-axis direction to a locking position S2, so that the anti-separation member 60 is moved across the male buckle member 20 to the female main body 31 of the female buckle member 30 and the front stop section 62 is able to overlap any part of the female-side coupling section 311 in the y-axis direction. Meanwhile, the front reinforcing stop section 63 overlaps the limiting block 316 of the female-side woven strap connection section 312 in the y-axis direction. Then, a first removal force F1 is applied to the male buckle member 20 for the latter to move rearward in the y-axis relative to the female buckle member 30. At this point, the front stop section 62 would get into contact with a front side of the female buckle member 30 and the front reinforcing stop section 63 is in contact with a front side of the limiting block 316 in the y-axis direction to prevent the male buckle member 20 from separating from the female main body 31.
[0096] Please refer to FIG. 16, which is an exploded perspective view of a magnetic fastening buckle 2 according to a third preferred embodiment of the present invention. In the third preferred embodiment, the magnetic fastening buckle 2 includes a male buckle member 20, a female buckle member 30, a set of retaining means 40, a set of magnetic attraction means 50, an anti-separation member 60, a set of locating means 70, a set of limiting mechanism 80, and a set of guiding means 90. The third preferred embodiment is different from the second one in that the male main body 21, the retaining means 40, and the anti-separation member 60 respectively have a structure different from that in the second preferred embodiment. Since the female buckle member 30, the magnetic attraction means 50, locating means 70, the limiting mechanism 80, and the guiding means 90 have structures the same as those in the second preferred embodiment, they are not repeatedly described herein.
[0097] As shown in FIG. 16, the male main body 21 of the male buckle member 20 has a male-side coupling section 211, which has a thickness smaller than that of a rear part of the male-side woven strap connection section 212; and the engaging space 421 and the retaining space 422 of the female-side retaining portion 42 are extended to a front side of the female main body 31 in the y-axis direction, such that the female-side retaining portion 42 further includes the front removal opening 427 formed at the front side of the female main body 31 in the y-axis direction to be communicable with both the engaging space 421 and the retaining space 422. That is, the front removal opening 427 is correspondingly located in front of and spaced from the rear removal opening 425. Further, the female-side retaining portion 42 further includes onesecondary anti-separation surface 428, which are two slant surfaces located at a front side of the anti-separation space 423 (referring to FIG. 17C). Also, the anti-separation member 60 further includes a rear stop section 64 and a rear reinforcing stop section 65. The rear stop section 64 is integrally formed with a lower end surface of the rear connection plate 613, and the rear reinforcing stop section 65 is integrally formed with a left side surface of the rear connection plate 613. When the top connection plate 611 of the connection section 61 is movably connected to an upper side of the male-side coupling section 211, the rear stop section 64 will pass over the male-side contact surface 213 of the male buckle member 20, such that the connection section 61 and the rear stop section 64 are located at an upper and a lower side, respectively, of the male-side contact surface 213. Meanwhile, the rear reinforcing stop section 65 has a height position higher than the male-side contact surface 213 of the male buckle member 20.
[0098] Please refer to FIGS. 17A to 17D, which depict the manner of moving the male buckle member 20 rearward in the y-axis direction to separate it from the female buckle member 30 according to the third preferred embodiment of the present invention. When the male-side retaining portion 41 of the retaining means 40 is engaged with the female-side retaining portion 42 of the retaining means 40, the anti-separation member 60 is located at an unlocking position S1 and the rear stop section 64 and the rear reinforcing stop section 65 of the anti-separation member 60 all are located at an outer side of the female main body 31. Meanwhile, the front stop section 62 of the anti-separation member 60 is located in front of the front removal opening 427 of the female-side retaining portion 42; and the rear stop section 64 is located behind the rear removal opening 425 of the female-side retaining portion 42, and the front and the rear reinforcing stop section 63, 65 of the anti-separation member 60 are staggered from the limiting block 316 of the female-side woven strap connection section 312, such that none of the front stop section 62, the front reinforcing stop section, 63, the rear stop section, 64, and the rear reinforcing stop section 65 can overlap any part of the female main body 31. Then, a first removal force F1 is applied to the male buckle member 20 to move the male buckle member 20 in the y-axis direction relative to the female buckle member 30, so that the retaining protrusions 412 of the male-side retaining portion 41 approach the rear removal opening 425 of the female-side retaining portion 42 gradually. When the retaining protrusions 412 are being moved toward the rear removal opening 425, the anti-separation block 413 of the male-side retaining portion 41 would get into contact with the anti-separation surface 426 of the anti-separation space 423. At this point, in the case the first removal force F1 has a magnitude large enough to drive the male buckle member 20 to separate from the female buckle member 30, the anti-separation block 413 would be moved to the engaging space 421 of the female-side retaining portion 42 while keep contacting with the anti-separation surface 426, such that the male buckle member 20 is movable relative to the female buckle member 30 in the x-axis and the y-axis direction at the same time and the front stop section 62 can be moved into one of the engaging space 421. When the front stop section 62 passes through the rear removal opening 425, the retaining protrusions 412 are separated from the retaining space 422 of the female-side retaining portion 42, allowing the male buckle member 20 to be removable from the female buckle member 30. At this point, the user may conveniently separate the male buckle member 20 from the female buckle member 30.
[0099] Please refer to FIG. 18A, which depicts the manner of moving the male buckle member 20 forward in the y-axis direction to separate it from the female buckle member 30 according to the third preferred embodiment of the present invention. In this case, a second removal force F2, that is opposite in direction to the first removal force F1, is applied to the male buckle member 20 to move the latter in the y-axis direction relative to the female buckle member 30, so that the retaining protrusions 412 of the male-side retaining portion 41 gradually approach the front removal opening 427 of the female-side retaining portion 42. When the retaining protrusions 412 are being moved toward the front removal opening 427, the anti-separation block 413 of the male-side retaining portion 41 would get into contact with the secondary anti-separation surface 428 of the anti-separation space 423. At this point, in the case the second removal force F2 has a magnitude large enough to drive the male buckle member 20 to separate from the female buckle member 30 and the anti-separation block 413 are moved to the engaging space 421 of the female-side retaining portion 42 while keep contacting with the secondary anti-separation surface 428, the male buckle member 20 can be moved relative to the female buckle member 30 in the x-axis and the y-axis direction at the same time, such that the rear stop section 64 of the anti-separation member 60 can be moved into the engaging space 421. Then, when the rear stop section 64 passes through the corresponding front removal opening 427, the retaining protrusions 412 are separated from the retaining space 422 of the female-side retaining portion 42, allowing the male buckle member 20 to be removed from the female buckle member 30. At this point, the user may conveniently separate the male buckle member 20 from the female buckle member 30.
[0100] Please refer to FIGS. 18B and 18C. In the case the second removal force F2 has a magnitude too small to drive the male buckle member 20 to separate from the female buckle member 30, the magnetic attraction force between the male-side magnet 51 and the female-side magnet 52 of the magnetic attraction means 50 enables the secondary anti-separation surface 428 of the anti-separation space 423 to drive the anti-separation block 413 of the male-side retaining portion 41 to move, such that the anti-separation block 413 are moved back into the anti-separation space 423 and it is ensured the retaining protrusions 412 of the male-side retaining portion 41 can engage with the retaining space 422 of the female-side retaining portion 42. In this manner, once the male buckle member 20 is assembled to the female buckle member 30, it is not a concern whether the male buckle member 20 would separate from the female buckle member 30 due to the secondary removal force F2. To the contrary, the magnetic fastening buckle 2 can be safer for use.
[0101] Please refer to FIGS. 19A to 19C, which depict the manner of preventing the male buckle member 20 from separating from the female buckle member 30 of the magnetic fastening buckle 2 according to the third preferred embodiment of the present invention. First, the anti-separation member 60 is moved in the x-axis direction to a locking position S2, so that the anti-separation member 60 is moved across the male buckle member 20 to the female main body 31 of the female buckle member 30, the front stop section and the rear stop section 62, 64 are able to overlap any part of the female-side coupling section 311 in the y-axis direction, and the front and rear reinforcing sections 63, 65 are able to overlap the limiting block 316 of the female-side woven strap connection section 312 in the y-axis direction. Then, a first removal force F1 is applied to the male buckle member 20 for moving the latter rearward in the y-axis direction relative to the female member 30. At this point, the front stop section 62 would contact with the front side of the female-side coupling section 311, and the front reinforcing stop section 63 would contact with a front side of the limiting block 316 in the y-axis direction, so as to prevent the male main body 21 from separating from the female main body 31. When a second removal force F2 is applied to the male buckle member 20 for moving the latter forward in the y-axis direction relative to the female buckle member 30, the rear stop section 64 would contact with the rear side of the female-side coupling section 311, and the rear reinforcing stop section 65 would contact with a rear side of the limiting block 316 in the y-axis direction, so as to prevent the male main body 21 from separating from the female main body 31.
[0102] Please refer to FIG. 20, which is an exploded perspective view of a magnetic fastening buckle 2 according to a fourth preferred embodiment of the present invention. In the fourth preferred embodiment, the magnetic fastening buckle 2 includes a male buckle ember, 20, a female buckle member 30, a set of retaining means 40, a set of magnetic attraction means 50, an anti-separation member 60, a set of locating means 70, a set of limiting mechanism 80, and a set of guiding means 90. The fourth preferred embodiment is different from the third one in that the anti-separation member 60 thereof has a structure different from that in the third preferred embodiment. Since the male buckle ember, 20, the female buckle member 30, the set of retaining means 40, the set of magnetic attraction means 50, the set of locating means 70, the set of limiting mechanism 80, and the set of guiding means 90 all are structurally similar to those in the third preferred embodiment, they are not repeatedly described herein.
[0103] As shown in FIG. 20, the anti-separation member 60 further includes a front limiting section 66 and a rear limiting section 67. The front limiting section 66 is formed on a lower end of the front reinforcing stop section 63 of the anti-separation member 60, such that the front limiting section 66 is spaced from and located below the top connection plate 611. The rear limiting section 67 is formed on a lower end of the rear reinforcing stop section 65 of the anti-separation member 60, such that the rear limiting section 67 is spaced from and located below the top connection plate 611.
[0104] In the Fourth preferred embodiment, except for one difference, the manners in which the male buckle member 20 is separated from and prevented from separating from the female buckle member 30 are generally the same as those in the third preferred embodiment, and are therefore not repeatedly described herein. Please refer to FIG. 21. The above said difference is that, when the anti-separation member 60 is moved to the locking position S2, the front and the rear limiting section 66, 67 of the anti-separation member 60 are respectively moved to a position below the limiting block 316. When the front and the rear limiting section 66, 67 of the anti-separation member 60 get into contact with a lower side of the limiting block 316, the male main body 21 is prevented from separating from the female main body 31 in the z-axis direction.
[0105] The present invention has been described with some preferred embodiments thereof and it is understood that many changes and modifications in the described embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
