[0338] 6F Second Magnet Detailed Implementation

[0339] To more clearly illustrate the overall concept of this application, a detailed explanation will be provided below with reference to the accompanying drawings.

[0340] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0341] Furthermore, it should be understood in the description of this application that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0342] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities connected are not linked by an intermediate structure, but are simply connected to form a whole. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0343] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0344] The fastener 100 of this application can be applied to products such as strollers, child safety seats, and infant carriers, but this application is not limited thereto.

[0345] The first embodiment of this application will be described below.

[0346] See Figure 1 and Figure 2 The fastener 100 may include a first fastener 1 and a second fastener 2. The second fastener 2 may be provided with a release mechanism 3. The first fastener 1 and the second fastener 2 can be interlocked along a third direction Z, thereby locking each other and making them inseparable. The release mechanism 3 can be actuated, thereby unlocking the first fastener 1 and the second fastener 2. The release mechanism 3 may be disposed on the second fastener 2 along a first direction X, and the release mechanism 3 may extend out of the second fastener 2. It should be noted that in this application, "first fastener" and "second fastener" are only used to distinguish the two fasteners and do not have specific meanings; the names "first fastener" and "second fastener" can also be used interchangeably. The release mechanism 3 may be generally formed as an elongated strip extending along the first direction X. Both ends of the release mechanism 3 can be pressed and compressed. The volume of the first fastener 1 may be larger than the volume of the second fastener 2, but this application is not limited thereto.

[0347] See Figure 1One end of the first fastener 1 (e.g., the end along the second direction Y) may have a connecting hole 111. The connecting hole 111 may be a rectangular through hole. A connecting rod 112 may extend within the connecting hole 111 along the first direction X. The first fastener 1 may be adjusted to connect a strap (not shown) via the connecting hole 111 and the connecting rod 112. For example, the strap may pass through the connecting hole 111 in one direction from one side of the connecting rod 112, then around the connecting rod 112 and through the connecting hole 111 in the opposite direction from the other side of the connecting rod 112, and finally around the connecting rod 112 again and through the connecting hole 111 again in the aforementioned direction from the same side of the connecting rod 112. The above method of the strap passing through the connecting hole 111 is merely an example; the strap may also pass through the connecting hole 111 in other ways, and this application is not limited thereto. After the strap is secured to the connecting hole 111 and the connecting rod 112, the first fastener 1 can be connected to the strap, and the length of the strap connected to the first fastener 1 can be adjusted. Alternatively, the connecting hole 111 may not have a connecting rod 112 or may have two connecting rods 112 that are parallel to each other and spaced a certain distance apart.

[0348] See Figure 2 Both ends of the second fastener 2 (e.g., both ends along the second direction Y) may have connecting holes 211. Two straps can pass through the two connecting holes 211 respectively and be connected to the second fastener 2. In this embodiment, the second fastener 2 may be fixed, while the first fastener 1 may be movable, but this application is not limited thereto. Alternatively, a connecting rod may also be provided in the connecting hole 211.

[0349] See Figure 3 The first fastener 1 may have a first fastener housing 11 and a first fastener body 12. The first fastener housing 11 may have an internal space, and the first fastener body 12 may be disposed within the internal space of the first fastener housing 11. The first fastener body 12 may be formed as a frame. The first fastener 1 may be provided with a first magnet 5. The second fastener 2 may be provided with a second magnet 6. The first fastener housing 11 may include a boss 113. The boss 113 may have a circular first boss portion 1131 and a second boss portion 1132 extending radially outward from the first boss portion 1131.

[0350] See Figure 3 , Figure 4 and Figure 4AThe first fastener body 12 may be formed as an approximately rectangular frame. The first fastener body 12 may include an outer frame 121 and connecting arms 123 connecting a first side and a second side (both sides along the second direction Y) of the outer frame 121. The connecting arms 123 may extend along the second direction Y, and both ends of the connecting arms 123 may be connected to the outer frame 121. The connecting arms 123 may bisect the first fastener body 12. The connecting arms 123 may have a first magnet receiving portion 122. The first magnet receiving portion 122 can be used to receive a first magnet 5. The first magnet receiving portion 122 can divide the connecting arms 123 into a first connecting arm portion 1231 and a second connecting arm portion 1232. In this embodiment, the length of the second connecting arm portion 1232 may be longer than the length of the first connecting arm portion 1231, but this application is not limited thereto. The outer frame 121 may include a lug portion 1211, which may protrude upwards, corresponding to the distance of the protrusion of the second boss portion 1132. The outer frame 121 may have recesses 1212 at its two opposite corners. The outer frame 121 may have locking spring arms 1217 at the recesses 1212. The locking spring arms 1217 extend along a second direction Y and have a free end. A blocking post 1215 is formed on the free end of the locking spring arms 1217. The blocking post 1215 extends along a third direction Z on the locking spring arms 1217. The inner side of the first fastener housing 11 may have a limiting blocking protrusion 115. The limiting blocking protrusion 115 extends into the interior of the first fastener housing 11 along a first direction X. When the first fastener body 12 is fixed inside the first fastener housing 11, the blocking post 1215 abuts against the limiting blocking protrusion 115 to prevent the first fastener body 12 from leaving the interior of the first fastener housing 11. The limiting blocking protrusion 115 may have a guide slope 1151. Correspondingly, the blocking post 1215 may have a mating slope 1216. The guide ramp 1151 may be located on the side of the limiting and blocking protrusion 115 away from the blocking post 1215. When the first fastener body 12 is inserted into the first fastener housing 11 along the second direction Y, the guide ramp 1151 contacts the mating ramp 1216 to cause the locking spring arm 1217 to elastically deform, allowing the first fastener body 12 to enter the interior of the first fastener housing 11. The lower parts of both sides of the outer frame 121 along the first direction X may respectively have a first engaging portion 1213 and a second engaging portion 1214. That is, relative to the connecting arm 123, the first engaging portion 1213 and the second engaging portion 1214 are formed on the third and fourth sides of the outer frame 121, respectively.

[0351] See also Figure 3 and Figure 4The release mechanism 3 may include a first button 31, a second button 32, a first engaging portion 33, a second engaging portion 34, and an elastic portion 35. The first button 31 and the second button 32 may be located at opposite ends of the release mechanism 3. The first button 31 and the second button 32 may be formed in a cuboid shape, but this application is not limited thereto. The first button 31 may have a first engaging portion 33 on its inner side. The second button 32 may have a second engaging portion 34 on its inner side. The first engaging portion 33 and the second engaging portion 34 may extend perpendicular to the movement direction of the first button 31 and the second button 32, respectively. In other words, the first engaging portion 33 and the second engaging portion 34 may extend upward along a third direction Z. The first engaging portion 33 and the second engaging portion 34 may be formed as hooks extending radially outward (or opposite to each other) along a first direction X. The elastic portion 35 may be located between the first engaging portion 33 and the second engaging portion 34. The first engaging portion 33 and the second engaging portion 34 can lock the first fastener 1 and the second fastener 2 by engaging the inner circumference of the first fastener 1 radially outward. Specifically, the first engaging portion 33 and the second engaging portion 34 can engage with the first engaged portion 1213 and the second engaged portion 1214 respectively.

[0352] In another embodiment, the first fastener 1 may be provided with a release operation member 3, and the first engaging part 33 and the second engaging part 34 can lock the first fastener 1 and the second fastener 2 by engaging the inner periphery of the second fastener 2 radially outward.

[0353] It is understood that in some embodiments, the first button 31, the second button 32, the first engaging portion 33, the second engaging portion 34, and the elastic portion 35 can be integrally formed. In other embodiments, the release operation member 3 may only have the first engaging portion 33 or the second engaging portion 34. Correspondingly, the first fastener body 12 may only have the first engaged portion 1213 or the second engaged portion 1214.

[0354] The elastic portion 35 may include a central portion 352 and a plurality of spring arms 351 located on both sides of the central portion 352. Each of the plurality of spring arms 351 may have a curved shape. Movement of the first button 31 and the second button 32 toward each other in a first direction causes elastic deformation of the plurality of spring arms 351. For example, the central portion 352 may have two spring arms 351 on each side. One end of each spring arm 351 may be connected to the central portion 352, and the other end of each spring arm 351 may be connected to one of the first button 31, the second button 32, the first engaging portion 33, and the second engaging portion 34. As another example, the elastic portion 35 may be formed in a shape similar to the number "8". The release operation member 3 may be integrally formed.

[0355] In other embodiments, the middle portion 352 may have one, three, or four spring arms 351 on each side. In other embodiments not shown, the middle portion 352 may be omitted, and the first button 31 and the second button 32 may be connected by the spring arms 351.

[0356] The second fastener 2 may have a second fastener body 21. A second magnet receiving portion 212 may be centrally located on the second fastener body 21. The second magnet receiving portion 212 is used to accommodate the second magnet 6. The second fastener body 21 may have a notch 213. Specifically, the second magnet receiving portion 212 may have a notch 213 on each side along the first direction X. The first button 31 and the second button 32 may be at least partially located in the notch 213. Figure 4 As shown, the inner notch 213 provides space for the movement of the first button 31, the second button 32, the first engaging part 33, and the second engaging part 34.

[0357] See Figure 3 and Figure 5 The first magnet 5 is fixed within the space enclosed by the first magnet receiving portion 122 and the first receiving portion cover 1221. The first magnet 6 is fixed within the space enclosed by the second magnet receiving portion 212 and the second receiving portion cover 2121. The elastic portion 35 can be fixed to the second fastener 2 via the intermediate portion 352. The intermediate portion 352 may have a hole 3521. The hole 3521 may be a screw hole, and the release operation member 3 can be fixed to the second receiving portion cover 2121 via a screw (not shown). Thus, when the first button 31 and / or the second button 32 is pressed, the corresponding spring arm 351 retracts and deforms, and the first button 31 and / or the second button 32 moves toward the intermediate portion 352. In other embodiments, the release operation member 3 may be fixed to the second fastener 2 by other means (e.g., rivets, snap-fit, etc.). When the first fastener 1 and the second fastener 2 are locked together, the first magnet 5 approaches the second magnet 6, and the first magnet 5 and the second magnet 6 at least partially overlap in the direction of mating (i.e., the third direction Z), such that the magnetic forces of the first magnet 5 and the second magnet 6 can influence each other. The magnetic poles of the first magnet 5 and the second magnet 6 facing each other can be opposite, thereby generating an attractive force to keep the first fastener 1 and the second fastener 2 from separating in the event of accidental activation of the first button 31 and the second button 32. Alternatively, the magnetic poles of the first magnet 5 and the second magnet 6 facing each other can be the same, thereby generating a repulsive force.

[0358] An opening may be provided at the bottom of the first fastener housing 11 to allow at least a portion of the second fastener 2 and the release operating member 3 to be inserted into the first fastener 1 from bottom to top along the third direction Z. The first engaging portion 1213 may have a first inclined surface 12131, and the second engaging portion 1214 may have a first inclined surface 12141. The first engaging portion 33 may have a second inclined surface 331, and the second engaging portion 34 may have a second inclined surface 341.

[0359] When the second fastener 2 is inserted into the first fastener 1 from bottom to top along the third direction Z, the second inclined surfaces 331 and 341 contact the first inclined surfaces 12131 and 12141 respectively, causing the first inclined surfaces 12131 and 12141 to actuate the second inclined surfaces 331 and 341 in a radially inward direction, thereby causing the spring arm 351 to elastically deform and contract. In this way, the first engaging portion 33 and the second engaging portion 34 will not prevent the second fastener 2 from being further inserted into the first fastener 1. When the first engaging portion 33 and the second engaging portion 34 move above the first engaged portion 1213 and the second engaged portion 1214, the spring arm 351 returns to its undeformed state due to its own elastic restoring force. At this time, the first engaged portion 1213 and the second engaged portion 1214 will prevent the first engaging portion 33 and the second engaging portion 34 from moving downward along the third direction Z, so that the second fastener 2 and the first fastener 1 are locked together. When the first engaging portion 33 and the second engaging portion 34 are just above the first engaged portion 1213 and the second engaged portion 1214, the second magnet receiving portion 212 abuts against the first magnet receiving portion 122, thereby preventing the second fastener 2 from being further inserted into the first fastener 1.

[0360] When it is necessary to unlock the first fastener 1 and the second fastener 2, the first button 31 and the second button 32 can be pressed radially inward along the first direction X. At this time, the first engaging part 33 and the second engaging part 34 move radially inward with the first button 31 and the second button 32 without being blocked by the first engaging part 1213 and the second engaging part 1214. Then, the magnetic attraction between the first magnet 5 and the second magnet 6 is overcome, and the second fastener 2 is pulled out from the inside of the first fastener 1, thereby separating the second fastener 2 and the first fastener 1. That is, the first button 31 and the second button 32 move relative to each other, causing the first engaging part 33 and the second engaging part 34 to move closer to each other and release the lock.

[0361] The second embodiment of this application will be described below.

[0362] See Figure 6 and Figure 7 The fastener 100 may include a first fastener 1 and a second fastener 2. The second fastener 2 may be provided with a release mechanism 3. The first fastener 1 and the second fastener 2 may be interlocked along a third direction Z, thereby locking each other and making them inseparable. The release mechanism 3 may be actuated, thereby unlocking the first fastener 1 and the second fastener 2. The release mechanism 3 may be disposed on the second fastener 2 along a first direction X, and the release mechanism 3 may extend beyond the second fastener 2. The release mechanism 3 may be generally formed as an elongated strip extending along the first direction X. Both ends of the release mechanism 3 may be pressed and compressed. The volume of the first fastener 1 may be larger than the volume of the second fastener 2, but this application is not limited thereto.

[0363] The connecting holes 111, 211 and connecting rod 112 of the second embodiment are the same as those of the first embodiment.

[0364] See Figure 8 The first fastener 1 may have a first fastener housing 11. The first fastener housing 11 may have an internal space, and an outer frame 121 may be disposed within the internal space of the first fastener housing 11. The first fastener 1 may be provided with a first magnet 5. The second fastener 2 may be provided with a second magnet 6. It is understood that the second embodiment may also omit the outer frame 121.

[0365] The first magnet 5 can be fixed within the space surrounded by the first magnet receiving portion 122 and the first receiving portion cover 1221. The first magnet 6 can be fixed within the space surrounded by the second magnet receiving portion 212 and the second receiving portion cover 2121. The elastic portion 35 of the second embodiment can be the same as that in the first embodiment. The structure of the elastic portion 35 of the second embodiment and its connection method with the second fastener 2 can be found in the first embodiment. The interaction between the first magnet 5 and the second magnet 6 in the second embodiment can be found in the first embodiment. The difference between the second embodiment and the first embodiment is that the first engaging portion 33 and the second engaging portion 34 can engage with the first fastener housing 11 respectively.

[0366] The lower part of the first fastener housing 11 may include a lower edge 114. The inner side of the lower edge 114 may define an opening for at least a portion of the second fastener 2 and the release operation member 3 to be inserted into the first fastener 1 from bottom to top along a third direction Z. The first engaging portion 33 may have a second bevel 331, and the second engaging portion 34 may have a second bevel 341.

[0367] When the second fastener 2 is inserted into the first fastener 1 from bottom to top along the third direction Z, the second inclined surfaces 331 and 341 respectively contact the lower edges 114 on both sides of the opening, causing the lower edges 114 to actuate the second inclined surfaces 331 and 341 in a radially inward direction, thereby causing the spring arm 351 to elastically deform and contract. In this way, the first engaging portion 33 and the second engaging portion 34 will not prevent the second fastener 2 from being further inserted into the first fastener 1. When the first engaging portion 33 and the second engaging portion 34 move above the first engaged portion 1213 and the second engaged portion 1214, the spring arm 351 returns to its undeformed state due to its own elastic restoring force. At this time, the lower edge 114 will prevent the first engaging portion 33 and the second engaging portion 34 from moving downward along the third direction Z, so that the second fastener 2 and the first fastener 1 are locked together. When the first engaging portion 33 and the second engaging portion 34 are just above the first engaged portion 1213 and the second engaged portion 1214, the second magnet receiving portion 212 abuts against the first magnet receiving portion 122, thereby preventing the second fastener 2 from being further inserted into the first fastener 1.

[0368] When it is necessary to unlock the first fastener 1 from the second fastener 2, the first button 31 and the second button 32 can be pressed radially inward along the first direction X. At this time, the first engaging part 33 and the second engaging part 34 move radially inward along with the first button 31 and the second button 32 without being blocked by the lower edge 114. Then, the magnetic attraction between the first magnet 5 and the second magnet 6 is overcome to pull the second fastener 2 out of the interior of the first fastener 1, thereby separating the second fastener 2 and the first fastener 1.

[0369] The third embodiment of this application will be described below.

[0370] See Figure 9 and Figure 10 The fastener 100 may include a first fastener 1 and a second fastener 2. The second fastener 2 may be provided with a release mechanism 3. The first fastener 1 and the second fastener 2 can be interlocked along a third direction Z to lock each other in place. The release mechanism 3 can be actuated to unlock the first fastener 1 and the second fastener 2. The release mechanism 3 may be disposed on the second fastener 2 and may extend out to one side of the second fastener 2. One end of the release mechanism 3 can be pressed and slid. The volume of the first fastener 1 may be smaller than the volume of the second fastener 2, but this application is not limited thereto.

[0371] See Figure 9 One end of the second fastener 2 (e.g., the end along the second direction Y) may have a connecting hole 231. The connecting hole 231 may be a rectangular through hole. A pivot 234 may extend within the connecting hole 231 along the first direction X. The second fastener 2 may be adjusted to connect a strap (not shown) via the connecting hole 231 and the pivot 234. After the strap is secured to the connecting hole 231 and the pivot 234, the second fastener 2 may be connected to the strap, and the length of the strap connected to the second fastener 2 may be adjusted. Alternatively, one or more connecting rods may be present within the connecting hole 231. Alternatively, the connecting hole 231 may not have a pivot 234.

[0372] See Figure 10 Both ends of the first fastener 1 (e.g., both ends along the second direction Y) may have connecting holes 111. Two straps may pass through the two connecting holes 111 respectively and be connected to the first fastener 1. Alternatively, connecting rods may be provided in the connecting holes 111.

[0373] See Figure 11The second fastener 2 may have a second fastener housing 22 and a second fastener outer shell 23. The second fastener outer shell 23 may have an internal space, and the second fastener housing 22 may be disposed within the internal space of the second fastener housing 23. The side of the second fastener housing 23 may have a housing receiving hole 233 for insertion into which the second fastener housing 22 is inserted. The second fastener housing 23 may have two pivot holes 232 for mounting a pivot 234. The two pivot holes 232 may be disposed on both sides of the connecting hole 231. The release operating member 3 may be partially inserted into the second fastener housing 22.

[0374] The first fastener 1 may have a first fastener body 12. The first fastener body 12 may have wings 124 at both ends along the second direction Y. The wings 124 facilitate the operator's gripping and control of the first fastener 1. The first fastener body 12 may have a locking portion 125. The locking portion 125 may be located at the center of the first fastener body 12, but this application is not limited thereto. The first fastener 1 may have a first magnet 5. The first magnet 5 may be located inside the locking portion 125. The second fastener 2 may have a second magnet 6. The second fastener housing 22 may have a second magnet receiving portion 221 to accommodate the second magnet 6.

[0375] The release mechanism 3 may include a button 31, an arm 36, a transition portion 37, and an engaging portion 33. The release mechanism 3 may be integrally formed. The release mechanism 3 may include two arms 36. The two arms 36 may extend parallel to each other from the button 31 toward the engaging portion 33, and are located on opposite sides of the engaging portion 125 along the second direction Y. In other embodiments, the two arms 36 may extend at an angle to each other. The release mechanism 3 includes only one button 31, which may extend at least partially from one side of the second fastener 2 in the first direction X. The engaging portion 33 may be formed in an arc shape. Specifically, the engaging portion 33 may be formed in a semi-circular arc shape. In other embodiments, the engaging portion 33 may be formed in an arc shape larger than a semicircle or smaller than a semicircle. The engaging portion 33 may engage with a portion of the outer periphery of the engaging portion 125. The release mechanism 3 may include two transition portions 37. Two transition portions 37 can respectively connect one end of the two arms 36 to the two ends of the engaging portion 33. The two transition portions 37 can be at an angle relative to the two arms 36, so that the engaging portion 33 and the two arms 36 are in different planes in the third direction Z. The transition portion 37 can be perpendicular to the arm 36 or the engaging portion 33 connected to it, but this application is not limited thereto. The dimension of the engaging portion 33 in the third direction Z can be smaller than the dimension of the arm 36 in the third direction Z, that is, the thickness of the engaging portion 33 can be smaller than the thickness of the arm 36. A larger thickness of the button 31 can improve the strength of the button 31 and provide a support point for the reset member 7. The smaller thickness of the engaging portion 33 facilitates engagement with the locking groove 1251 (described in detail below) of the locking portion 125 of the first fastener 1. In other embodiments, the thickness of the arm 36 can be the same as the thickness of the engaging portion 33. The release operation member 3 can be formed in annular shape. In other words, the button 31, arm 36, transition portion 37, and engaging portion 33 can enclose a certain space. The locking portion 125 can be located within this space. The button 31 and the engaging portion 33 can be located on opposite sides of the locking portion 125 along the first direction, respectively.

[0376] See Figure 11 and Figure 14 The fastener 100 may include a reset member 7. The reset member 7 may be a coil spring, but this application is not limited thereto. The reset member 7 may be disposed between the second fastener 2 and the release operation member 3 to provide a reset force that tends to engage the engaging portion 33 with the locking portion 125. A reset member receiving groove 311 is formed on the side of the button 31 facing the engaging portion 33. One end of the reset member 7 may be located within the reset member receiving groove 311. The other end of the reset member 7 may be fixed to the spring mounting portion 235 of the second fastener housing 22. The spring mounting portion 235 may be located on the inner wall of the second fastener housing 22.

[0377] See Figure 11 and Figure 14The locking part 125 may have a first magnet receiving part 122 inside. The first magnet receiving part 122 may be a recess that is open on one side. The cover 13 may close the open end of the first magnet receiving part 122, thereby fixing the first magnet 5 inside the first magnet receiving part 122. The second magnet 6 located in the second magnet receiving part 221 may be fixed by the second fastener housing 21 and the second magnet receiving part 221 respectively.

[0378] See Figure 14 and Figure 15 The locking portion 125 may protrude upward along a third direction Z from the first fastener body 12. The locking portion 125 may have a locking groove 1251 and a third inclined surface 1252. The locking portion 125 may be formed in a cylindrical shape, and both the locking groove 1251 and the third inclined surface 1252 are formed in a circle around the outer periphery of the locking portion 125. The locking groove 1251 is used to engage with the engaging portion 33. The engaging portion 33 may have a second inclined surface 331. The third inclined surface 1252 and the second inclined surface 331 may cooperate with each other to actuate the engaging portion 33 along a first direction X.

[0379] See Figures 12 to 15 When the first fastener 1 is inserted into the second fastener 2 from bottom to top along the third direction Z, the third inclined surface 1252 abuts against the second inclined surface 331, causing the release operating member 3 to overcome the reset force of the reset member 7 and move to the right along the first direction X. In this way, the engaging part 33 avoids the locking part 125, allowing the release operating member 3 to move further upward. After the locking part 125 passes the third inclined surface 1252, the reset member 7 pushes the release operating member 3, causing the engaging part 33 to enter the locking groove 1251. At this time, the first fastener 1 abuts against the second fastener 2, preventing the first fastener 1 from further entering the second fastener 2, and the engaging part 33 is engaged in the locking groove 1251, preventing the first fastener 1 from separating from the second fastener 2 (i.e., the first fastener 1 and the second fastener 2 are locked together).

[0380] When the first fastener 1 and the second fastener 2 are locked together, the first magnet 5 approaches the second magnet 6 along the third direction Z, and the first magnet 5 and the second magnet 6 at least partially overlap in the direction of mating (i.e., the third direction Z), such that the magnetic forces of the first magnet 5 and the second magnet 6 can influence each other. The magnetic poles of the first magnet 5 and the second magnet 6 facing each other can be opposite, thereby generating an attractive force to keep the first fastener 1 and the second fastener 2 from separating when the button 31 is accidentally pressed. Alternatively, the magnetic poles of the first magnet 5 and the second magnet 6 facing each other can be the same, thereby generating a repulsive force.

[0381] When it is necessary to unlock the first fastener 1 from the second fastener 2, the button 31 can be pressed along the first direction X. At this time, the button 31 moves against the reset force of the reset member 7, causing the engaging part 33 to leave the locking groove 1251. Then, the magnetic attraction between the first magnet 5 and the second magnet 6 is overcome to pull the first fastener 1 out of the second fastener 2, thereby separating the first fastener 1 and the second fastener 2.

[0382] The fourth embodiment of this application will be described below.

[0383] See Figure 17 and Figure 18 The fastener 100 may include a first fastener 1 and a second fastener 2. The second fastener 2 may be provided with a release mechanism 3. The first fastener 1 and the second fastener 2 can be interlocked along a third direction Z to lock each other in place. The release mechanism 3 can be actuated to unlock the first fastener 1 and the second fastener 2. The release mechanism 3 may be disposed on the second fastener 2 and may extend out to one side of the second fastener 2. One end of the release mechanism 3 can be pressed and slid. The volume of the first fastener 1 may be smaller than the volume of the second fastener 2, but this application is not limited thereto.

[0384] See Figure 17 One end of the second fastener 2 (e.g., the end along the second direction Y) may have a connecting hole 231. The connecting hole 231 may be a rectangular through hole. The second fastener 2 may form a ramp at the connecting hole 231, such that the thickness is thinner towards the edge. A pivot 234 may extend within the connecting hole 231 along the first direction X. One or more connecting rods 236 may be present within the connecting hole 231. The connecting rod 236 of the fourth embodiment is the same as the connecting rod 112 of the first embodiment, and will not be described again here. Alternatively, the connecting hole 231 may have the same pivot as in the third embodiment.

[0385] See Figure 18 Both ends of the first fastener 1 (e.g., both ends along the second direction Y) may have connecting holes 111. The connecting holes 111 in the fourth embodiment may be the same as those in the third embodiment, and will not be described again here.

[0386] See Figure 20 The second fastener 2 may have an internal space. The release mechanism 3 may be partially inserted into the housing 22 of the second fastener.

[0387] See Figure 19 and Figure 20 The first fastener 1 may be provided with a locking portion 125. The locking portion 125 may be located at the center of the first fastener 1, but this application is not limited thereto. The first fastener 1 may be provided with a first magnet 5. The first magnet 5 may be located inside the locking portion 125.

[0388] The release mechanism 3 may be provided with a second magnet 6. The release mechanism 3 may have a second magnet receiving portion 38 to receive the second magnet 6. The release mechanism 3 may include a button 31, an arm 36, and an engaging portion 33. The release mechanism 3 may be integrally formed. The release mechanism 3 may include two arms 36. The two arms 36 may extend parallel to each other from the button 31 toward the engaging portion 33, and are respectively located on opposite sides of the engaging portion 125 along the second direction Y. In other embodiments, the two arms 36 may extend at an angle to each other. The release mechanism 3 includes only one button 31, which may extend at least partially from one side of the second fastener 2 in the first direction X. The edge of the engaging portion 33 facing the button 31 may be formed in an arc shape. Specifically, the edge of the engaging portion 33 facing the button 31 may be formed in a semi-circular arc shape. In other embodiments, the edge of the engaging portion 33 facing the button 31 may be formed in an arc shape larger than a semi-circle or smaller than a semi-circle. The engaging portion 33 can engage with a portion of the outer periphery of the locking portion 125. The dimension (i.e., thickness) of the release operating member 3 in the third direction Z can be uniform or equal. The release operating member 3 can be annular. In other words, the button 31, the arm 36, and the engaging portion 33 can enclose a certain space. The locking portion 125 can be located within this space.

[0389] The fourth embodiment may have the same reset element 7 as the third embodiment, which will not be described again here.

[0390] The arrangement of the first magnet 5 in the fourth embodiment is the same as that in the third embodiment, and will not be described again here.

[0391] See Figures 18 to 20 The second fastener 2 may have a second magnet receiving portion 38. The second magnet receiving portion 38 may be located on the side of the engaging portion 33 away from the button 31. The second magnet receiving portion 38 may seal the second magnet 6.

[0392] At least one of the first magnet 5 and the second magnet 6 may be in the shape of a cuboid or a cube. Preferably, both the first magnet 5 and the second magnet 6 are in the shape of a cuboid or a cube. The volume of the first magnet 5 may be larger than the volume of the second magnet 6, but this application is not limited thereto. Alternatively, one of the first magnet 5 and the second magnet 6 may be in the shape of a cuboid or a cube, while the other of the first magnet 5 and the second magnet 6 may be in the shape of a cylinder.

[0393] When the first fastener 1 and the second fastener 2 are locked together, the first magnet 5 and the second magnet 6 can at least partially overlap along the first direction X (i.e., at least partially align along the first direction X).

[0394] See Figure 19The locking portion 125 may protrude downwards from the first fastener body 12 along a third direction Z. The locking portion 125 may have a locking groove 1251 and a third inclined surface 1252. The locking portion 125 may be formed in a cylindrical shape, and both the locking groove 1251 and the third inclined surface 1252 are formed in a circle around the outer periphery of the locking portion 125. The locking groove 1251 is used to engage with the engaging portion 33. The engaging portion 33 may have a second inclined surface 331. The third inclined surface 1252 and the second inclined surface 331 may cooperate with each other to actuate the engaging portion 33 along a first direction X.

[0395] When the first fastener 1 is inserted into the second fastener 2 from top to bottom along the third direction Z, the third inclined surface 1252 can abut against the second inclined surface 331, causing the release operating member 3 to overcome the reset force of the reset member 7 and move to the right along the first direction X. In this way, the engaging part 33 avoids the locking part 125, allowing the release operating member 3 to move further downward. After the locking part 125 passes the third inclined surface 1252, the reset member 7 will push the release operating member 3, causing the engaging part 33 to enter the locking groove 1251. At this time, the first fastener 1 abuts against the second fastener 2, preventing the first fastener 1 from further entering the second fastener 2, and the engaging part 33 is engaged in the locking groove 1251, preventing the first fastener 1 from separating from the second fastener 2 (i.e., the first fastener 1 and the second fastener 2 are locked together).

[0396] When the first fastener 1 and the second fastener 2 are locked together, the first magnet 5 approaches the second magnet 6 along the first direction X, and the first magnet 5 and the second magnet 6 at least partially overlap along the first direction Z, such that the magnetic forces of the first magnet 5 and the second magnet 6 can influence each other. The magnetic poles of the first magnet 5 and the second magnet 6 facing each other can be opposite, thereby generating an attractive force to keep the first fastener 1 and the second fastener 2 from separating when the button 31 is accidentally pressed. Specifically, see Figure 19 The first magnet 5 and the second magnet 6 can be located on both sides of the locking groove 1251 and the engaging part 33 along the first direction X, respectively, so as to improve the locking reliability of the locking groove 1251 and the engaging part 33.

[0397] When it is necessary to unlock the first fastener 1 from the second fastener 2, the button 31 can be pressed along the first direction X. At this time, the button 31 moves against the reset force of the reset member 7 and the magnetic attraction between the first magnet 5 and the second magnet 6, causing the engaging part 33 to leave the locking groove 1251. Then, the first fastener 1 is pulled out from the inside of the second fastener 2 along the third direction Z, thereby separating the first fastener 1 and the second fastener 2.

[0398] The fifth embodiment of this application will now be described.

[0399] See Figure 21 and Figure 22The fastener 100S may include a second fastener 1S and a first fastener 2S. The second fastener 1S may be provided with a release operation element 3S. The second fastener 1S and the first fastener 2S can be interlocked along a third direction Z to lock each other inseparably. The release operation element 3S can be actuated to unlock the second fastener 1S and the first fastener 2S. The release operation element 3S may be disposed on the second fastener 1S along a third direction Z, and the release operation element 3S may extend out of the second fastener 1S. That is, as... Figure 21 As shown, the release operation element 3S is movably disposed on the upper side of the second fastener 1S. The release operation element 3S may be circular, but this application is not limited thereto.

[0400] It should be noted that in this application, "first fastener" and "second fastener" are only used to distinguish between the two fasteners and do not have a specific meaning. The names "first fastener" and "second fastener" can also be used interchangeably.

[0401] See Figure 21 One end of the second fastener 1S (e.g., the end along the second direction Y) may have a connecting hole 111S. The connecting hole 111S may be a rectangular through hole. The connecting rod 112S may extend within the connecting hole 111S along the first direction X. The second fastener 1S may be adjusted to connect a strap (not shown) via the connecting hole 111S and the connecting rod 112S. For example, the strap may pass through the connecting hole 111S from one side of the connecting rod 112S in one direction, then around the connecting rod 112S and through the connecting hole 111S from the other side of the connecting rod 112S in the opposite direction, and finally around the connecting rod 112S again and through the connecting hole 111S again from the same side of the connecting rod 112S in the same direction. The above method of the strap passing through the connecting hole 111S is only an example, and the strap may pass through the connecting hole 111S in other ways, which are not limited to this application. After the strap is secured to the connecting hole 111S and the connecting rod 112S, the second fastener 1S can be connected to the strap, and the length of the strap connected to the second fastener 1S can be adjusted. Alternatively, the connecting hole 111S may not have a connecting rod 112S or may have two connecting rods 112S that are parallel to each other and spaced apart.

[0402] In this application, the first direction X, the second direction Y, and the third direction Z can be mutually perpendicular.

[0403] See Figure 22 Both ends of the first fastener 2S (e.g., both ends along the second direction Y) may have connecting holes 23S. Two straps can pass through the two connecting holes 23S respectively and be connected to the first fastener 2S. In this embodiment, the first fastener 2S may be fixed, while the second fastener 1S may be movable, but this application is not limited thereto. Alternatively, a connecting rod may also be provided in the connecting hole 23S.

[0404] See Figure 23 and Figure 24 The second fastener 1S may have a second fastener housing 11S and a second fastener body 12S. The second fastener housing 11S may have an internal space, and the second fastener body 12S may be disposed within the internal space of the second fastener housing 11S. The second fastener body 12S may be formed as a frame. The second fastener 1S may be provided with a first magnet 5S. The first fastener 2S may be provided with a second magnet 6S.

[0405] The second fastener housing 11S may have an opening at the bottom so that at least a portion of the first fastener 2S can be inserted into the second fastener 1S from bottom to top along the third direction Z.

[0406] The second fastener body 12S can be formed as an approximately rectangular frame. The second fastener body 12S may include an outer frame 121S and connecting arms 123S connecting a first side and a second side (both sides along the second direction Y) of the outer frame 121S. The connecting arms 123S can extend along the second direction Y, and both ends of the connecting arms 123S can be connected to the outer frame 121S. The connecting arms 123S can bisect the second fastener body 12S. The connecting arms 123S may have a first magnet receiving portion 122S. The first magnet receiving portion 122S can be used to receive a first magnet 5S. The first magnet receiving portion 122S and the first magnet 5S can be formed as circles, but this application is not limited thereto. The first magnet receiving portion 122S may have a magnet latching portion 1222S. The magnet latching portion 1222S can fix the first magnet 5S within the first magnet receiving portion 122S. The first magnet accommodating portion 122S may have four magnet latching portions 1222S, but this application is not limited thereto. The first magnet accommodating portion 122S can divide the connecting arm 123S into a first connecting arm portion 1231S and a second connecting arm portion 1232S. In this embodiment, the length of the second connecting arm portion 1232S may be longer than the length of the first connecting arm portion 1231S, but this application is not limited thereto.

[0407] The outer frame 121S may include a lug 1211S that protrudes upward. The outer frame 121S may have recesses 1212S at two opposite corners. The outer frame 121S may have a locking spring arm 1217S at the recess 1212S. The locking spring arm 1217S extends along a second direction Y and has a free end. A blocking post 1215S is formed on the free end of the locking spring arm 1217S. The blocking post 1215S extends along a third direction Z on the locking spring arm 1217S. The inner side of the second fastener housing 11S may have a limiting blocking protrusion (not shown). The limiting blocking protrusion extends into the interior of the second fastener housing 11S along a first direction X. When the second fastener body 12S is fixed inside the second fastener housing 11S, the blocking post 1215S abuts against the limiting blocking protrusion to prevent the second fastener body 12S from leaving the interior of the second fastener housing 11S. The limiting stop protrusion may have a guide ramp (not shown). Correspondingly, the stop post 1215S may have a mating ramp 1216S. The guide ramp may be located on the side of the limiting stop protrusion away from the stop post 1215S. When the second fastener body 12S is inserted into the second fastener housing 11S along the second direction Y, the guide ramp contacts the mating ramp 1216S to elastically deform the locking spring arm 1217S, allowing the second fastener body 12S to enter the interior of the second fastener housing 11S.

[0408] The first fastener 2S may have a locking portion 21S. The locking portion 21S may be located at the center of the first fastener 2S, but this application is not limited thereto. The second fastener 1S may have a locking portion 125S and a pushing ramp 117S. The pushing ramp 117S may be formed on the inner surface of the second fastener housing 11S. The locking portion 125S may be located between the release operating member 3S and the pushing ramp 117S. The release operating member 3S may include a release pushing portion 32S. The release pushing portion 32S may be formed in an annular shape, but this application is not limited thereto. The release pushing portion 32S may extend in the third direction Z. The locking portion 125S may include a lock head 1253S capable of locking with the locking portion 21S. Figure 24 As shown, the release push part 32S, the lock head 1253S, and the push ramp 117S can be at least partially aligned along the third direction Z, but this application is not limited thereto. The push ramp 117S and the release operation member 3S can be located on both sides of the lock head 1253S along the third direction Z.

[0409] In other embodiments, the release operation member 3S, the locking part 125S and the pushing slope 117S may be provided on the first fastener 2S, and the locking part 21S may be provided on the second fastener 1S.

[0410] The unlocking mechanism 3S applies pressure to the lock head 1253S in the direction of the mating engagement of the second fastener 1S and the first fastener 2S (i.e., the third direction Z), causing the lock head 1253S to move away from the locking part 21S along the pushing slope 117S, thereby unlocking it from the locking part 21S. In other words, as... Figure 24 As shown, when the release pusher 32S pushes the lock head 1253S downward, the lock head 1253S moves along the pusher ramp 117S in the first direction X and the third direction Z (outward and downward). Specifically, the release pusher 32S pushes the lock head force-receiving part 1257S of the lock head 1253S (see... Figure 23 ).

[0411] See Figure 23 The locking part 125S may further include a spring arm 1254S. The spring arm 1254S may be integrally formed with the lock head 1253S and connected to the second fastener body 12S. In some embodiments, when the locking part 125S is in the locked state, the spring arm 1254S may be parallel to the connecting arm 123S. The spring arm 1254S may apply a spring force to the lock head 1253S to lock the lock head 1253S with the locking part 21S. The spring arm 1254S may be elastically deformable.

[0412] In this embodiment, the second fastener 1S may include two locking parts 125S, each locking part 125S may include a spring arm 1254S and a lock head 1253S. The two locking parts 125S may be symmetrically located on both sides of the connecting arm 123S. The lock heads 1253S of the two locking parts 125S may together surround most of the outer periphery of the first magnet receiving part 122S.

[0413] See Figure 24 A lock head flat surface 1255S and a lock head inclined surface 1256S may be formed on the lock head 1253S. The locking part 21S may have a push part 211S, a locking groove 212S, and a locking part opening 213S. A locking inclined surface 2111S and a locking flat surface 2112S may be formed on the push part 211S. When the first fastener 2S and the second fastener 1S are engaged, the locking inclined surface 2111S engages with the lock head inclined surface 1256S to push the lock head 1253S away from the locking part 21S. Then, the first fastener 2S and the second fastener 1S may further approach each other and lock each other. When the first fastener 2S and the second fastener 1S are locked together, the lock head flat surface 1255S is located in the locking groove 212S and abuts against the locking flat surface 2112S to form a lock. When the lock cylinder 1253S is unlocked from the locking part 21S, the release operation member 3S is pressed, so that the push-up inclined surface 117S and the lock cylinder inclined surface 1256S cooperate to push the lock cylinder 1253S away from the locking part 21S.

[0414] See Figure 24An operation reset member 7S may be provided between the release operation member 3S and the first magnet receiving portion 122S. The operation reset member 7S may be a helical spring, but this application is not limited thereto. The operation reset member 7S may abut against the inner surface of the release operation member 3S and the reset member receiving portion 1223S of the first magnet receiving portion 122S, respectively. The release operation member 3S may include a through hole 31S. The through hole 31S is located on the side of the release operation member 3S away from the second fastener 1S (i.e., on the upper side of the release operation member 3S). The through hole 31S facilitates observation of the interior of the second fastener 1S and facilitates installation, disassembly, and maintenance.

[0415] See Figure 25 When the second fastener 1S and the first fastener 2S are engaged, the first magnet 5S and the second magnet 6S can be at least partially aligned along the engagement direction (third direction Z), so that the magnetic forces of the first magnet 5S and the second magnet 6S can influence each other. In this embodiment, the first magnet 5S and the second magnet 6S can be partially offset in the second direction Y. In other embodiments, the first magnet 5S and the second magnet 6S can be partially offset in the first direction X, or the first magnet 5S and the second magnet 6S can be partially offset in both the first direction X and the second direction Y. The magnetic poles of the first magnet 5S and the second magnet 6S facing each other can be opposite, thereby generating an attractive force to keep the second fastener 1S and the first fastener 2S from separating when the first button 31S and the second button 32S are accidentally pressed. Alternatively, the magnetic poles of the first magnet 5S and the second magnet 6S facing each other can be the same, thereby generating a repulsive force.

[0416] See Figure 26 The locking opening 213S exposes the second magnet 6S. That is, the side of the second magnet accommodating portion 22S facing the first magnet accommodating portion 122S is open, thereby bringing the first magnet 5S and the second magnet 6S closer together. Optionally, the side of the first magnet accommodating portion 122S facing the second magnet accommodating portion 22S is open, or both the sides of the first magnet accommodating portion 122S and the second magnet accommodating portion 22S facing each other are open.

[0417] The sixth embodiment of this application will be described below.

[0418] See Figure 27 and Figure 28 The buckle 100S of the sixth embodiment has a similar shape to the buckle 100S of the fifth embodiment in terms of the shape of the second buckle 1S and the first buckle 2S. A cover 34S may be provided on the release operation member 3S to close the through hole 31S. The cover 34S may be detachable.

[0419] See Figures 29 to 31The fastener 100S also includes a lock head reset member 8S. The lock head reset member 8S can be disposed between the second fastener body 12S and the lock head 1253S to apply a spring force to the lock head 1253S, tending to lock the lock head 1253S with the locking part 21S. The lock head reset member 8S can be a coil spring, but this application is not limited thereto. Specifically, the fastener 100S includes two lock heads 1253S and two lock head reset members 8S corresponding to the two lock heads 1253S.

[0420] In other words, in the sixth embodiment, the lock head 1253S is disposed within the second fastener 1S, and locking or unlocking with the locking part 21S is achieved by means of the lock head reset member 8S, without the need for a spring arm. Specifically, the lock head 1253S can be connected to the second fastener body 12S by means of the lock head reset member 8S. One end of the lock head reset member 8S abuts against the third or fourth side (one side along the first direction X) of the second fastener body 12S, and the other end of the lock head reset member 8S abuts against the middle position of the outer side of the lock head 1253S, but this application is not limited thereto. In other embodiments not shown, the lock head 1253S can also be movably disposed within the second fastener 1S by means of other fixing structures.

[0421] See Figure 30 and Figure 31 The release push part 32S may have a push slope 321S. When the release operation member 3S is pressed, the push slope 321S can push the lock head 1253S outward along the first direction X away from the locking part 21S, thereby unlocking. That is to say, the second fastener housing 11S in the sixth embodiment may not have a push slope 117S.

[0422] See Figures 29 to 31 When the first fastener 2S and the second fastener 1S are engaged, the locking ramp 2111S of the locking part 21S pushes the lock head 1253S away from the locking part 21S. Then, the first fastener 2S and the second fastener 1S can move closer to each other and lock each other. When the first fastener 2S and the second fastener 1S are locked together, a portion of the lock head 1253S is located in the locking groove 212S, so that the lock head 1253S is locked by the locking part 21S. When the lock head 1253S is unlocked from the locking part 21S, the release operation member 3S is pressed, so that the push ramp 321S on the release operation member 3S engages with the lock head 1253S to push the lock head 1253S away from the locking part 21S, thereby allowing the locking part 21S to leave the second fastener 1S.

[0423] Other features of the sixth embodiment can be found in the fifth embodiment.

[0424] The seventh embodiment of this application will be described below.

[0425] See Figure 32 and Figure 33The first fastener 2S may have an operating member receiving portion 24S. The operating member receiving portion 24S may be formed in an approximate "pocket" shape. The release operating member 3S is movably disposed within the operating member receiving portion 24S. The release operating member 3S is partially disposed within the operating member receiving portion 24S.

[0426] See Figure 35 The first fastener 2S has a locking part 21S. The locking part 21S and the unlocking operation part 3S are sequentially arranged on the first fastener 2S along the second direction Y. The second fastener 1S may have a first magnet receiving part 122S (see...). Figure 34A The first fastener 2S may have a second magnet receiving portion 22S to receive the second magnet 6S. The lower side of the second magnet receiving portion 22S may be open.

[0427] See Figures 34A to 34C The locking part 125S may include a lock head 1253S. In an embodiment not shown, the locking part 125S may also include a spring arm. Optionally, the locking part 125S may only include a lock head 1253S. The second fastener 1S may include two locking parts 125S, which may be symmetrically located on both sides of the connecting arm 123S along the first direction X. The lock head 1253S may be formed in a curved shape to surround a portion of the locking part 21S. The release operation member 3S may be movably disposed on the first fastener 2S along the second direction Y to actuate the locking part 125S (specifically, the lock head 1253S) along the first direction X. The locking part 125S may include two lock heads 1253S. The two lock heads 1253S are respectively disposed on opposite sides of the locking part 21S along the first direction X. The second fastener 1S and the first fastener 2S are mated together along the third direction Z. The release operation member 3S may have a release push part 32S. The release push portion 32S may have a straight shape, but is not limited thereto. In other embodiments, the release push portion 32S may be a bent structure. The release operating member 3S may have two release push portions 32S parallel to each other, but this application is not limited thereto. The free end of the release push portion 32S may have a push ramp 321S. The push ramps 321S on the two release push portions 32S may face outward. When the two release push portions 32S move along the second direction Y toward the two locking portions 125S, the push ramps 321S of the two release push portions 32S may respectively abut against the lock heads 1253S of the two locking portions 125S, thereby pushing the lock heads 1253S of the two locking portions 125S to move outward in the first direction X (e.g., away from each other).

[0428] See Figure 36 The operating member receiving portion 24S may have clearance holes 241S to allow the release push portion 32S to pass through the operating member receiving portion 24S. The number of clearance holes 241S may be the same as the number of release push portions 32S.

[0429] See Figure 34A and Figure 34B The second fastener body 12S may have a clearance recess 1218S. The clearance recess 1218S may be formed at the bottom of the outer frame 121S to allow the release push portion 32S to pass through the second fastener body 12S. The number of clearance recesses 1218S may be the same as the number of release push portions 32S.

[0430] See Figure 34C The second fastener housing 11S may have a bottom opening 119S and a clearance recess 1218S. The clearance recess 1218S may be located near the bottom of the second fastener housing 11S to allow the release pusher 32S to pass through and enter the second fastener housing 11S. The number of clearance recesses 1218S may be the same as or different from the number of release pushers 32S. The locking part 21S may enter the interior of the second fastener housing 11S through the bottom opening 119S. The clearance recesses 1218S and the bottom opening 119S may communicate with each other, but this application is not limited thereto.

[0431] See Figure 34A The fastener 100S also includes a lock head reset member 8S. The lock head reset member 8S can be disposed between the outer frame 121S of the second fastener body 12S and the lock head 1253S to apply a spring force to the lock head 1253S, tending to lock the lock head 1253S with the locking part 21S. The lock head reset member 8S can be a coil spring, but this application is not limited thereto. Specifically, the fastener 100S includes two lock heads 1253S and two lock head reset members 8S corresponding to the two lock heads 1253S. The two lock heads 1253S can be disposed on both sides of the connecting arm 123S along a first direction X. The lock heads 1253S can be locked or unlocked with the locking part 21S by means of the lock head reset member 8S. Specifically, the lock heads 1253S can be connected to the second fastener body 12S by means of the lock head reset member 8S. One end of the lock head reset member 8S abuts against the third or fourth side (one side along the first direction X) of the second fastener body 12S, and the other end of the lock head reset member 8S abuts against the middle position of the outer side of the lock head 1253S, but this application is not limited thereto. In other embodiments not shown, the lock head 1253S may also be movably disposed within the second fastener 1S by other fixing structures.

[0432] See Figures 34A to 36 When it is necessary to unlock the second fastener 1S from the first fastener 2S, press the release operation member 3S. The release operation member 3S moves along the second direction Y, causing the pushing slope 321S of the release push part 32S to abut against the lock head 1253S, and pushes the lock head 1253S outward along the first direction X, thereby disengaging the lock head 1253S from the locking part 21S.

[0433] At least one of the first magnet accommodating portion 122S and the second magnet accommodating portion 22S can be rectangular, square, or other non-circular. Correspondingly, at least one of the first magnet 5S and the second magnet 6S can be rectangular, square, or other non-circular.

[0434] Other features of the seventh embodiment can be found in the fifth embodiment.

[0435] The eighth embodiment of this application will be described below.

[0436] See Figure 37 and Figure 38 The buckle 100S of the eighth embodiment has a similar shape to the buckle 100S of the seventh embodiment in terms of the shape of the second fastener 1S and the first fastener 2S. A cover 34S may be provided on the release operation member 3S to close the through hole 31S. The cover 34S may be detachable.

[0437] See Figures 39 to 41 The fastener 100S may have a locking part 125S. The locking part 125S may have a lock head 1253S and a spring arm 1254S. The lock head 1253S, the spring arm 1254S, and the outer frame 121S may be integrally formed, but this application is not limited thereto. In some embodiments, the lock head 1253S, the spring arm 1254S, and the outer frame 121S may also be separate structures, and the lock head 1253S may be connected to the outer frame 121S via the spring arm 1254S. The lock head 1253S may be located on the side of the first magnet receiving part 122S away from the release operation member 3S along the second direction Y. In other words, the lock head 1253S may be located on the side of the locking part 21S away from the release operation member 3S along the second direction Y. The lock head may have a semi-circular arc structure, but is not limited thereto. The spring arm 1254S may be located on the side of the lock head 1253S away from the release operation member 3S. The spring arm 1254S can be formed into a zigzag shape to provide elastic force along the second direction Y. The release operating member 3S may have a release pushing portion 32S. The release pushing portion 32S may be straight and gradually taper, but is not limited thereto. The release operating member 3S may have two release pushing portions 32S, but this application is not limited thereto.

[0438] The second fastener body 12S may include a first connecting arm 1231S (that is, in the eighth embodiment, the connecting arm 123S includes only the first connecting arm 1231S and not the second connecting arm 1232S). The first connecting arm 1231S may be disposed on a first side of the second fastener body 12S (e.g., the side closer to the release operation member 3S along the second direction Y). The spring arm 1254S may be disposed on the opposite second side (e.g., the side away from the release operation member 3S along the second direction Y). In some embodiments, the positions of the first connecting arm 1231S and the spring arm 1254S are interchanged, that is, the spring arm 1254S may be disposed on the side closer to the release operation member 3S, and the release push portion 32S may apply a pulling force to the lock head 1253S. The first connecting arm 1231S may extend along the second direction Y, and both ends of the first connecting arm 1231S may be connected to the outer frame 121S and the first magnet receiving portion 122S.

[0439] See Figure 39 The second fastener body 12S may have a clearance recess 1218S. The clearance recess 1218S may be formed at the bottom of the outer frame 121S to allow the release push portion 32S to pass through the second fastener body 12S. The number of clearance recesses 1218S may be the same as the number of release push portions 32S. In other embodiments, the number of clearance recesses 1218S may be different from the number of release push portions 32S.

[0440] The first magnet accommodating portion 122S and the second magnet accommodating portion 22S can be circular. Correspondingly, the first magnet 5S and the second magnet 6S can be circular.

[0441] See Figure 41 The second fastener housing 11S may include a decorative cover 113S. The decorative cover 113S may cover a portion of the second fastener housing 11S, thereby serving a decorative purpose. The decorative cover 113S may be generally a rectangular flat plate, and may be formed into an arc shape on one side, but this application is not limited thereto.

[0442] See Figures 39 to 41When the first fastener 2S and the second fastener 1S are engaged, the locking ramp 2111S of the locking part 21S pushes the lock head 1253S away from the locking part 21S in the second direction Y. Then, the first fastener 2S and the second fastener 1S can further approach each other and lock each other. When the first fastener 2S and the second fastener 1S are locked together, a portion of the lock head 1253S is located in the locking groove 212S, so that the lock head 1253S is locked by the locking part 21S. When the lock head 1253S is unlocked from the locking part 21S, the release operation member 3S is pressed, so that the two release push parts 32S push the lock head 1253S in the second direction Y, so that the lock head 1253S is away from the locking part 21S in the first direction X and / or the second direction Y, so that the lock head 1253S is no longer engaged with the locking part 21S, thereby allowing the locking part 21S to leave the second fastener 1S.

[0443] Other features of the eighth embodiment can be found in the fifth and seventh embodiments.

[0444] The ninth embodiment of this application will be described below.

[0445] See Figures 42 to 46 The fastener 100T may include a first fastener 1T, a second fastener 2T, and a release / locking mechanism 3T. The fastener 100T may also include two elastic elements 6T. The second fastener 2T may contain a locking part 4T, and the first fastener 1T may include a mating locking part 5T. The mating locking part 5T can be used to cooperate with the locking part 4T. The first fastener 1T and the second fastener 2T are aligned along the mating direction (e.g., ...). Figure 49 The direction indicated by the middle arrow P (also known as the "first direction") is used to align the locking part 4T with the side of the fastener 100T (e.g., ...). Figure 47 The directions indicated by the middle arrows M1 and M2 (also referred to as the "second direction") are locked with the mating locking part 5T. The mating direction can be staggered with the lateral direction. Preferably, the mating direction can be perpendicular to the lateral direction. The release operation member 3T can be provided in the second fastener 2T and linked to the locking part 4T. Specifically, the release operation member 3T can be partially provided in the second fastener 2T. The movement of the release operation member 3T in the lateral direction can push the locking part 4T to move in the lateral direction, so that the locking part 4T is unlocked from the mating locking part 5T. The locking part 4T can be formed independently of the second fastener 2T, rather than integrally formed.

[0446] In this embodiment, the first fastener 1T can be a first fastener and the second fastener 2T can be a female fastener. Of course, depending on the actual situation, in another embodiment, the first fastener can be a female fastener and the second fastener can be a male fastener, so it is not limited to this.

[0447] See Figure 42 and Figure 47The release mechanism 3T is embedded within the second fastener 2T and is linked to the locking part 4T. The release mechanism 3T may also partially protrude from the side wall of the second fastener 2T and can move relative to the second fastener 2T along the side direction. Figures 47 to 50 As shown, during its movement along the lateral direction, the release mechanism 3T drives the locking part 4T to move away from the mating locking part 5T along the lateral direction of the second fastener 2T, thereby releasing the locking part 4T from the mating locking part 5T. The direction of movement of the release mechanism 3T is the same as the direction in which it drives the locking part 4T to release, ensuring that the force applied by the operator to the release mechanism 3T is fully transmitted to the locking part 4T along its direction of movement, and that the locking part 4T is released by the full force of the release mechanism 3T. This prevents the force applied by the operator from being dispersed in directions other than the lateral direction, making the unlocking operation less strenuous and more convenient for the user.

[0448] See Figure 42 and Figure 43 The interlocking locking part 5T is located on the front of the first fastener 1T, and the second fastener 2T has an interlocking hole 21T for the interlocking locking part 5T to be inserted. The interlocking direction of the first fastener 1T and the second fastener 2T is as follows (e.g., Figure 49 The direction indicated by the middle arrow P) and the direction of movement of the release mechanism 3T (e.g., Figure 47 The directions indicated by the middle arrows M1 and M2 are intersecting. Preferably, the insertion direction of the first fastener 1T and the second fastener 2T is perpendicular to the moving direction of the release operating member 3T. This allows the thickness of the fastener 100T in the insertion direction to be reduced during manufacturing, thereby improving the internal space utilization of the fastener 100T.

[0449] See Figure 42 and Figure 43 The first fastener 1T may have wings 12T at its upper and lower ends respectively. The wings 12T facilitate sewing the first fastener 1T onto the seat. In other embodiments, the upper or lower end of the first fastener 1T may have wings 12T. Optionally, the first fastener 1T may have holes for connecting to a connecting strap (not shown).

[0450] See Figures 42 to 44 The second fastener 2T may include a first housing 201T, a second housing 202T, and a pivot 203T. The first housing 201T and the second housing 202T may be joined together to enclose a certain internal space. The pivot 203T may be disposed within a hole in the first housing 201T for connection to a connecting strap (not shown). See also Figure 44The locking part 4T may have an elastic structure. The unlocking operation member 3T drives the locking part 4T to move away from the mating locking part 5T along the side direction of the second fastener 2T, so that the elastic structure undergoes elastic deformation, and the locking part 4T and the mating locking part 5T are unlocked.

[0451] Specifically, see Figure 44 The locking part 4T includes a first locking part 4aT located on one side of the mating locking part 5T and a second locking part 4bT located on the opposite side of the mating locking part 5T. The first locking part 4aT and the second locking part 4bT can engage with the mating locking part 5T along the lateral direction. The unlocking operation member 3T may include a first unlocking operation member 3aT arranged on the same side as the first locking part 4aT and a second unlocking operation member 3bT arranged on the same side as the second locking part 4bT. The first unlocking operation member 3aT abuts against the second locking part 4bT. The second unlocking operation member 3bT abuts against the first locking part 4aT. By driving the second locking part 4bT away from the mating locking part 5T through the first unlocking operation member 3aT and the second unlocking operation member 3bT driving the first locking part 4aT away from the mating locking part 5T, the first locking part 4aT and the second locking part 4bT are disengaged from the mating locking part 5T. Therefore, the cooperation between the first unlocking operation member 3aT, the second unlocking operation member 3bT, the first locking part 4aT, and the second locking part 4bT makes the locking and unlocking processes more reliable.

[0452] In other embodiments, the release mechanism and the locking mechanism may be one, three, or four, etc.

[0453] See Figure 44 The first locking part 4aT includes a first lock head 42aT for locking with the mating locking part 5T and a first reset member 44aT disposed between the first lock head 42aT and the second fastener 2T. The first reset member 44aT may be a coil spring, but this application is not limited thereto. The first reset member 44aT always has a tendency to drive the first lock head 42aT to lock with the mating locking part 5T along the lateral direction. The second release operation member 3bT is used to drive the first reset member 44aT to make an elastic deformation away from the mating locking part 5T, so as to release the first lock head 42aT from the mating locking part 5T.

[0454] The second locking part 4bT includes a second lock head 42bT for locking with the mating locking part 5T and a second reset member 44bT disposed between the second lock head 42bT and the second fastener 2T. The second reset member 44bT may be a coil spring, but this application is not limited thereto. The second reset member 44bT always has a tendency to drive the second lock head 42bT to lock with the mating locking part 5T along the lateral direction. The first release operation member 3aT is used to drive the second reset member 44bT to make an elastic deformation away from the mating locking part 5T, so as to release the second lock head 42bT from the mating locking part 5T.

[0455] See Figure 44 and Figure 47 The pushing portion extends along the second direction and abuts against the lock head. The first unlocking operating member 3aT has a first pushing portion 31aT protruding along the side direction. The second lock head 42bT is provided with a second mating top 43bT that is connected to the first pushing portion 31aT. During the movement of the first unlocking operating member 3aT along the side direction, the first pushing portion 31aT pushes the second mating top 43bT, causing the second lock head 42bT to resist the reset force of the second reset member 44bT and move away from the mating locking portion 5T, thereby releasing the second lock head 42bT from the mating locking portion 5T. The second unlocking operating member 3bT has a second pushing part 31bT protruding along the side direction. The first lock head 42aT is provided with a first mating top 43aT that is linked to the second pushing part 31bT. During the movement of the second unlocking operating member 3bT along the side direction, the second pushing part 31bT pushes the first mating top 43aT, causing the first lock head 42aT to resist the reset force of the first reset member 44aT and move away from the mating locking part 5T, thereby unlocking the first lock head 42aT from the mating locking part 5T. The first mating top 43aT can be located at the upper end of the first lock head 42aT (near the end of the first unlocking operating member 3aT). The second mating top 43bT can be located at the upper end of the second lock head 42bT (near the end of the second unlocking operating member 3bT).

[0456] Optionally, the first top part 43aT can be aligned with the second pushing part 31bT along the side direction, and the second top part 43bT can be aligned with the first pushing part 31aT along the side direction, thereby making the pushing of the release operation member 3T more precise and the release operation more labor-saving.

[0457] The first pushing part 31aT and the second pushing part 31bT can overlap at least partially along the interlocking direction P, thereby saving space within the second fastener. Specifically, the first mating top 43aT and the second mating top 43bT are arranged at different heights in the interlocking direction P (also known as the "height direction") of the fastener 100T, and the first pushing part 31aT and the second pushing part 31bT are also arranged at different heights in the interlocking direction P of the fastener 100T. In this way, the pushing movements of the first pushing part 31aT and the second pushing part 31bT are located at different heights, so that the movement of the first pushing part 31aT and the second pushing part 31bT along the lateral direction will not interfere with each other, thus ensuring the reliability of the unlocking.

[0458] For example, the second pusher portion 31bT has the same height as the first mating top portion 43aT, the first pusher portion 31aT has the same height as the second mating top portion 43bT, and the height of the second pusher portion 31bT and the first mating top portion 43aT is higher than the height of the first pusher portion 31aT and the second mating top portion 43bT, but this application is not limited thereto.

[0459] In one embodiment, the first top part 43aT is offset from the second top part 43bT along the lateral direction, and the first pushing part 31aT is also offset from the second pushing part 31bT along the lateral direction, thereby reducing the space occupied by the first top part 43aT and the second top part 43bT in the height direction. Offsetting the first top part 43aT and the second top part 43bT along the lateral direction is more conducive to the spatial arrangement of the fastener 100T.

[0460] In one embodiment, the first pushing portion 31aT and the second mating portion 43bT protrude in a direction perpendicular to the interlocking direction and the side direction (e.g., Figure 47 The direction indicated by the middle arrow Q (also referred to as the "third direction") is ahead of the positions of the second pushing part 31bT and the first mating top 43aT in the protruding direction, but is not limited thereto. That is to say, as Figure 47 As shown, the first pushing part 31aT and the second fitting top 43bT are positioned higher than the second pushing part 31bT and the first fitting top 43aT.

[0461] See Figure 44 , Figure 49 and Figure 50The mating locking part 5T has a push structure 51T and a locking structure 52T. During the mating process of the first fastener 1T and the second fastener 2T, the push structure 51T pushes the first lock head 42aT and the second lock head 42bT, causing the first reset member 44aT and the second reset member 44bT to be compressed, and then moving the first lock head 42aT and the second lock head 42bT to a position where they engage with the locking structure 52T. The first release operating member 3aT and the second release operating member 3bT can be pressed to drive the first lock head 42aT and the second lock head 42bT away from the locking structure 52T, thereby releasing the lock.

[0462] Optionally, the end of the pushing structure 51T has a first inclined structure 511T inclined to the insertion direction, and the first lock head 42aT and the second lock head 42bT may each have a second inclined structure 421T that matches the first inclined structure 511T. During the insertion of the first fastener 1T and the second fastener 2T, the pushing structure 51T moves past the lock head and to the position where the locking structure 52T engages with the lock head by means of the pushing of the first inclined structure 511T against the second inclined structure 421T. For example, the locking structure 52T is an annular groove, and the lock head is used to engage with the annular groove.

[0463] See Figure 44 , Figure 47 and Figure 48 The fastener 100T may include an elastic element 6T. The elastic element 6T may be disposed between the release operation member 3T and the second fastener 2T. The elastic element 6T always has a tendency to drive the release operation member 3T to move away from the locking part 4T, so that the release operation member 3T can be reset after being released due to the elasticity of the elastic element 6T. Specifically, the second fastener 2T has a first baffle 24T and a second baffle 26T that abut against the elastic element 6T. The first baffle 24T abuts against one end of the elastic element 6T, while the second baffle 26T abuts against the upper side of the elastic element 6T. The first baffle 24T and the second baffle 26T may be integrally formed and staggered. Preferably, the first baffle 24T and the second baffle 26T may be at a 90° angle. Specifically, the fastener 100T may include two elastic elements 6T. Each of the two elastic elements 6T abuts against one first baffle 24T and one second baffle 26T. The two first baffles 24T are located between the two elastic elements 6T.

[0464] The first release operating member 3aT and the second release operating member 3bT of the release operating member 3T are respectively provided with limiting protrusions 33T. The second fastener 2T has two limiting blocks 25T that abut against the limiting protrusions 33T. Under the action of the limiting blocks 25T and the limiting protrusions 33T, the second fastener 2T prevents the first release operating member 3aT and the second release operating member 3bT of the release operating member 3T from sliding off from the second fastener 2T.

[0465] See Figures 44 to 47 The locking part 4T is engaged with the second fastener 2T. Preferably, the locking part 4T and the second fastener 2T are detachably engaged, so either the locking part 4T or the second fastener 2T can be replaced if either is damaged. In addition, this simplifies the manufacturing process of the fastener 100T of this application.

[0466] The second fastener 2T may have positioning rods 27T in different directions. The positioning rods 27T can abut against the locking part 4T to prevent undesirable movement of the locking part 4T within the second fastener 2T. The locking part 4T may include a positioning fork 46T. The positioning fork 46T can cooperate with a positioning rod 27T extending in the projection direction Q to jointly limit the second magnetic structure 8T. Optionally, the positioning fork 46T can also be used to jointly limit the locking part 4T with the positioning rods 27T on its left and right sides. The left and right sides of the positioning fork 46T ( Figure 47 or Figure 48 The positioning rods 27T on the left and right sides of the locking part 4T can be mounted on the housing (first housing 201T or second housing 202T) of the second fastener 2T, and are located on the side of the locking part 4T away from the first mating top 43aT and the second mating top 43bT. The positioning rods 27T on the left and right sides of the positioning fork 46T are mainly used to limit the movement of the locking part 4T. When the release operation 3T is operated to release the lock, the release operation 3T cooperates with the positioning rods 27T on the left and right sides of the positioning fork 46T to allow the first end of the locking part 4T (the end near the first mating top 43aT or the second mating top 43bT) to move stably open and squeeze the elastic member 44T. When the release operation 3T is released, the elastic member 44T can provide a restoring force to allow the locking part 4T to stably return to the position where it is engaged with the mating locking part 5T. The locking part 4T is also provided with a positioning part 45T. Specifically, the first lock head 42aT and the second lock head 42bT are both provided with positioning parts 45T. One end of the elastic element 44T abuts against the positioning part 45T, and the other end abuts against the first housing 201T of the second fastener 2T. The positioning part 45T may be located in the middle position between the first lock head 42aT and / or the second lock head 42bT.

[0467] See Figure 44 , Figure 49 and Figure 50The fastener 100T of this application further includes a first magnetic structure 7T and a second magnetic structure 8T. The first magnetic structure 7T is disposed on the first fastener 1T, and the second magnetic structure 8T is disposed on the second fastener 2T. The first magnetic structure 7T and the second magnetic structure 8T are magnetically attracted to each other during the insertion of the first fastener 1T and the second fastener 2T. This makes the fastening of the first fastener 1T and the second fastener 2T faster, and even if the locking part 4T and the mating locking part 5T are disengaged, the first fastener 1T and the second fastener 2T remain engaged due to the mutual magnetic attraction of the first magnetic structure 7T and the second magnetic structure 8T, thereby preventing accidental release and ensuring the safety of the fastener 100T of this application.

[0468] In another embodiment, the first magnetic structure 7T and the second magnetic structure 8T can magnetically repel each other during the insertion of the first fastener 1T and the second fastener 2T, so as to make unlocking more convenient.

[0469] The first fastener 1T has a first embedding cavity 11T, and the second fastener 2T has a second embedding cavity 23T. A first magnetic structure 7T is embedded in the first embedding cavity 11T, and a second magnetic structure 8T is embedded in the second embedding cavity 23T. The first embedding cavity 11T is aligned with the second embedding cavity 23T along the insertion direction to strengthen the adsorption force between the first magnetic structure 7T and the second magnetic structure 8T; however, this application is not limited to this. Specifically, the second embedding cavity 23T is aligned with the space between the first lock head 42aT and the second lock head 42bT along the insertion direction, making the fastener 100T of this application compact and space-efficient. The cover 9T can cover the first embedding cavity 11T, thereby isolating the first magnetic structure 7T from the outside environment.

[0470] See Figures 47 to 50The working principle of the buckle 100T of this application will now be explained. During the unlocking operation, the user overcomes the elastic force of the two elastic elements 6T and simultaneously presses the first unlocking operating element 3aT and the second unlocking operating element 3bT. The first pushing part 31aT of the first unlocking operating element 3aT pushes the second mating top 43bT, and the second pushing part 31bT of the second unlocking operating element 3bT pushes the first mating top 43aT, thereby causing the first lock head 42aT and the second lock head 42bT to overcome the reset force of the first reset element 44aT and the second reset element 44bT and move away from the mating locking part 5T respectively. At this time, the buckle 100T is in a releasable state. While keeping the first unlocking operating element 3aT and the second unlocking operating element 3bT pressed, the first fastener 1T and the second fastener 2T can be pulled apart to completely unlock the buckle 100T. After the first release mechanism 3aT and the second release mechanism 3bT are released, the elastic member 6T drives the first release mechanism 3aT and the second release mechanism 3bT to reset. The first reset member 44aT and the second reset member 44bT respectively drive the first lock head 42aT and the second lock head 42bT to reset. When it is necessary to lock the first fastener 1T and the second fastener 2T, the mating locking part 5T is aligned with the mating hole 21T and inserted. The pushing structure 51T simultaneously pushes the first lock head 42aT and the second lock head 42bT away from the mating locking part 5T to both sides, so that the first lock head 42aT and the second lock head 42bT move to the position where they are locked with the locking structure 52T.

[0471] While the first release mechanism 3aT and the second release mechanism 3bT are described in the ninth embodiment, it is understood that in other embodiments, the fastener 100T may have only the first release mechanism 3aT or the second release mechanism 3bT. Similarly, in other embodiments, the fastener 100T may have only a push portion, a locking portion, a top fitting, or a reset member.

[0472] The tenth embodiment of this application will be described below.

[0473] See Figure 51 and Figure 52 The locking part 4T may include a first lock head 42aT, a second lock head 42bT, a first spring arm 41aT, and a second spring arm 41bT. The first lock head 42aT and the first spring arm 41aT may be integrally formed. The second lock head 42bT and the second spring arm 41bT may be integrally formed. The first spring arm 41aT and the second spring arm 41bT may respectively replace the first reset member 44aT and the second reset member 44bT to provide elastic reset force for the first lock head 42aT and the second lock head 42bT, so that the first lock head 42aT and the second lock head 42bT tend to lock with the mating locking part 5T. The first spring arm 41aT may be formed at the end of the first lock head 42aT away from the elastic member 6T (i.e., Figure 51The lower end of the second spring arm 41bT may be formed at the end of the second lock head 42bT away from the elastic element 6T (i.e., Figure 51 (Lower end of the middle). The first spring arm 41aT may be parallel to the second spring arm 41bT, but this application is not limited thereto.

[0474] The locking part 4T may further include a locking support frame 44T. The end of the first spring arm 41aT away from the first lock head 42aT and the end of the second spring arm 41bT away from the second lock head 42bT may be integrally formed with the locking support frame 44T. The locking support frame 44T may include a connecting portion 442T and an extension portion 443T. The connecting portion 442T may be substantially perpendicular to the first spring arm 41aT or the second spring arm 41bT. In other words, the connecting portion 442T may be along the lateral direction (e.g., Figure 47 (As indicated by the middle arrows M1 and M2) The extension portion 443T extends from the connecting portion 442T between the first elastic arm 41aT and the second elastic arm 41bT. The extension portion 443T can be formed into a "T" shape. The extension portion 443T can limit the degree of inward deformation of the first elastic arm 41aT and the second elastic arm 41bT to avoid damage to the first elastic arm 41aT and the second elastic arm 41bT.

[0475] The locking part 4T may further include a first fixing part 411aT and a second fixing part 411bT. The first fixing part 411aT and the second fixing part 411bT may be located at both ends of the connecting part 442T and are annular in shape. The first fixing part 411aT and the second fixing part 411bT can play a fixing role to stably fix the locking part 4T to the second fastener 2T.

[0476] The first locking head 42aT is provided with a first mating top 43aT that is linked to the second pushing part 31bT. The first mating top 43aT is located on the first locking head 42aT along the interlocking direction (e.g., ...). Figure 49 (As indicated by the arrow P). During its movement along the lateral direction, the second unlocking mechanism 3bT pushes the first mating top 43aT with the second pushing part 31bT, causing the first spring arm 41aT to elastically deform and the first lock head 42aT to move away from the mating locking part 5T, thereby unlocking the first lock head 42aT from the mating locking part 5T. The second lock head 42aT is provided with a second mating top 43bT that is linked to the first pushing part 31aT. The second mating top 43bT extends along the mating direction (e.g., as indicated by the arrow P) of the second lock head 42aT. Figure 49 (The direction indicated by the middle arrow P) extends. During the movement of the first unlocking operating member 3aT along the said lateral direction, the first pushing part 31aT pushes the second mating top 43bT, causing the second spring arm 41bT to elastically deform and the second lock head 42bT to move away from the mating locking part 5T, thereby releasing the second lock head 42bT from the mating locking part 5T.

[0477] See Figure 52 The second locking head 43bT can be located at the middle position of the second locking head 42bT along the third direction Q. The first locking head 43aT can be located between the second locking head 43bT and the first spring arm 41aT along the third direction Q. That is to say, as Figure 52 As shown, the distance from the top of the first fitting 43aT to the upper end of the first lock head 42aT is greater than the distance from the top of the first fitting 43aT to the lower end of the first lock head 42aT.

[0478] The first mating top 43aT may include a first segment 431aT and a second segment 432aT. The first segment 431aT of the first mating top 43aT may be perpendicular to the second segment 431bT of the first mating top 43aT, such that the first mating top 43aT is formed in an "L" shape. The second mating top 43bT may include a first segment 431bT, a second segment 432bT, and a third segment 433bT. The first segment 431bT and the third segment 433bT of the second mating top 43bT may be located at both ends of the second segment 432bT of the second mating top 43bT. In other embodiments, the first mating top 43aT and the second mating portion 43bT may have the same shape and each have two or three segments.

[0479] Optionally, the first mating top 43aT may be located in the protruding direction of the first lock head 42aT (e.g., ...). Figure 47 The lower part (closer to the first spring arm 41aT) of the second locking head 42bT in the direction indicated by the middle arrow Q, and the top of the second locking head 43bT may be located in the middle part of the second locking head 42bT in the protruding direction.

[0480] Optionally, the first top part 43aT can be aligned with the second pushing part 31bT along the side direction, and the second top part 43bT can be aligned with the first pushing part 31aT along the side direction, thereby making the pushing of the release operation member 3T more precise and the release operation more labor-saving.

[0481] The first pushing portion 31aT and the second pushing portion 31bT can overlap at least partially along the interlocking direction P, thereby saving space within the second fastener. Specifically, the first mating top 43aT and the second mating top 43bT are arranged at different heights in the interlocking direction P (also known as the "height direction") of the fastener 100T, and the first pushing portion 31aT and the second pushing portion 31bT are arranged at different heights in the interlocking direction P of the fastener 100T. In this way, the pushing movements of the first pushing portion 31aT and the second pushing portion 31bT are located at different heights, so that the movement of the first pushing portion 31aT and the second pushing portion 31bT along the lateral direction will not interfere with each other, thus ensuring the reliability of the unlocking. In other embodiments not shown, the first pushing portion 31aT and the second pushing portion 31bT may not overlap along the interlocking direction P, making the thickness of the second fastener 2T thinner.

[0482] The first segment 431aT of the first mating top 43aT can limit the movement of the first pushing part 31aT along the lateral direction, thereby making the movement of the first pushing part 31aT more stable. The first segment 431bT of the second mating top 43bT can limit the movement of the second pushing part 31bT along the lateral direction, thereby making the movement of the second pushing part 31bT more stable. The first segment 431aT of the first mating top 43aT can improve the structural strength of the first mating top 43aT. The first segment 431bT and the third segment 433bT of the second mating top 43bT can improve the structural strength of the second mating top 43bT. The first mating top 43aT and the second mating top 43bT can be located on the same side of the locking part 4T, that is, on the side away from the mating locking part 5T in the mating direction P. In this way, the first mating top 43aT and the second mating top 43bT can not affect the engagement of the first fastener 1T and the second fastener 2T, and the thickness of the second fastener 2T can be thinner.

[0483] The eleventh embodiment of this application will now be described.

[0484] See Figure 53 The fastener 100F of this application may include a first fastener 1F and a second fastener 2F. The first fastener 1F and the second fastener 2F can be interlocked. The first fastener 1F and the second fastener 2F can be locked or unlocked. It should be noted that in this application, "first fastener" and "second fastener" are only used to distinguish the two fasteners and do not have specific meanings, and the names "first fastener" and "second fastener" can be used interchangeably.

[0485] The first fastener 1F may include a body 11F. The body 11F may have a symmetrical shape, but this application is not limited thereto. The body 11F may have a locking portion 12F. The locking portion 12F may be centrally located on the body 11F and may protrude from the body 11F. The locking portion 12F may be cylindrical, but this application is not limited thereto. A cavity may be formed inside the locking portion 12F (see [link to relevant documentation]). Figure 57A The first magnet 5F can be located inside the locking part 12F. The sealing member 14F can seal the first magnet 5F inside the locking part 12F. Holes 13F can be formed on both sides of the body 11F. The holes 13F can be connected to the webbing to constrain the position of the first fastener 1F relative to the webbing. A push-up slope 121F and a locking groove 122F can be formed on the locking part 12F. The push-up slope 121F can be located on the outer periphery of the top of the locking part 12F. The locking groove 122F can be located between the push-up slope 121F and the body 11F, and surround the locking part 12F. The first fastener 1F can be formed in a generally rectangular shape, but this application is not limited to this.

[0486] The second fastener 2F may include a housing 20F and a release assembly 23F. The housing 20F may include a base 21F and a cover 22F. The release assembly 23F may be disposed between the base 21F and the cover 22F. A second magnet 6F may be provided in the second fastener 2F. The base 21F and the cover 22F may enclose a space to form a cavity for receiving the release assembly 23F. The cavity may have an opening to allow the release assembly 23F to partially protrude. The second fastener 2F may be formed in a generally rectangular shape, but this application is not limited thereto.

[0487] See Figure 54 The release assembly 23F may include a pressing portion 231F, a resilient structure 232F, and a locking head 234F. The pressing portion 231F may extend at least partially out of the cavity surrounded by the base 21F and the cover 22F, thereby allowing the pressing portion 231F to be pressed from outside the cavity. The pressing portion 231F may slide laterally X relative to the base 21F and the cover 22F. One end of the resilient structure 232F may be connected to the pressing portion 231F. The other end of the resilient structure 232F may be connected to the locking head 234F.

[0488] See Figure 54 and Figure 55The elastic structure 232F can be a curved linear structure. The curvature of the elastic structure 232F is lateral to the fastener 100F. In this application, "vertical direction" refers to the direction in which the first fastener 1F and the second fastener 2F interlock, and "lateral" refers to the direction perpendicular to the vertical direction Z, or the direction within the plane formed by the transverse direction X and the longitudinal direction Y. The elastic structure 232F may include a first segment 2321F and a second segment 2323F. The cover 22F may include a protrusion 221F. The protrusion 221F may be cylindrical, but this application is not limited thereto. In other embodiments, the protrusion 221F may be square, rectangular, or other shaped protrusions. The protrusion 221F may be disposed on the housing 20F. Specifically, the protrusion 221F may be disposed on the cover 22F and extend from the cover 22F toward the base 21F in the vertical direction Z. In another embodiment, the protrusion 221F may be disposed on the base 21F. The protruding post 221F can contact the base 21F, but this application is not limited thereto. The dimension of the protruding post 221F in the vertical direction Z can be larger than the dimension of the first segment 2321F in the vertical direction Z. The elastic structure 232F can abut against the protruding post 221F. Specifically, as Figure 55 As shown, the protrusion 221F contacts the inner side of the elastic structure 232F. The first segment 2321F is on the side of the protrusion 221F closer to the pressing part 231F, while the second segment 2323F is on the side of the protrusion 221F away from the pressing part 231F. When the pressing part 231F is pressed inward from the outside of the second fastener 2F, the first segment 2321F moves inward along with the pressing part 231F and undergoes elastic deformation. Since the protrusion 221F abuts against the elastic structure 232F, the second segment 2323F moves outward (towards the outer periphery of the second fastener 2F). Specifically, when the pressing part 231F is actuated, the deformation direction of the first segment 2321F is opposite to the movement direction of the second segment 2323F.

[0489] Optionally, the elastic structure 232F may have a protrusion 2322F. The curvature of the protrusion 2322F may differ from the curvature of other parts of the elastic structure 232F (e.g., the curvature of the protrusion 2322F is greater than the curvature of other parts of the elastic structure 232F), and it protrudes towards the outer periphery of the second fastener. That is, the protrusion 2322F can be formed by bending the elastic structure 232F. The protrusion 2322F may be formed in the second segment 2323F, near the portion of the elastic structure 232F that contacts the protrusion 221F, but this application is not limited thereto.

[0490] See Figure 54 and Figure 55The engaging head 234F may be formed in the form of a sheet. The engaging head 234F may be connected to the end of the resilient structure 232F away from the pressing part 231F. That is, the engaging head 234F may be connected to one end of the second segment 2323F. The base 21F may include a receiving hole 211F. When the pressing part 231F is not actuated, the engaging head 234F may be partially located within the receiving hole 211F. When the pressing part 231F is actuated, the resilient structure 232F may deform, thereby causing the engaging head 234F to move away from the receiving hole 211F.

[0491] See Figure 53 and Figure 57A The locking part 12F can be inserted into the receiving hole 211F to lock with the engaging head 234F. Specifically, the engaging head 234F can be inserted into the locking groove 122F of the locking part 12F along the side of the fastener 100F, thereby preventing the locking part 12F from leaving the receiving hole 211F in the vertical direction Z.

[0492] Optionally, the release assembly 23F includes a locking head connector 233F. The locking head connector 233F has a curved shape and connects the locking head 234F to the elastic structure 232F. The locking head connector 233F may have a certain degree of elasticity. The extending directions of the locking head connector 233F and the locking head 234F may be perpendicular to the movement direction of the pressing part 231F, but this application is not limited thereto. Therefore, the first segment 2321F and the second segment 2323F extend circumferentially on the outer side of the housing 20F, while the locking head 234F extends circumferentially on the inner side of the housing 20F.

[0493] like Figure 54 and Figure 55 As shown, the release assembly 23F may include two pressing portions 231F, four resilient structures 232F, and four engaging heads 234F. The two pressing portions 231F are located on opposite sides of the base 21F. Each pressing portion 231F is connected to two of the four resilient structures 232F. Each resilient structure 232F is connected to one of the four engaging heads 234F (e.g., via an engaging head connector 233F).

[0494] In one embodiment, the release assembly 23F may include a pressing part 231F, two resilient structures 232F, and two engaging heads 234F. The pressing part 231F is located on one side of the base 21F. The pressing part 231F is connected to the two resilient structures 232F. Each resilient structure 232F is connected to one of the two engaging heads 234F.

[0495] In one embodiment, the release assembly 23F may include two pressing portions 231F, two resilient structures 232F, and two engaging heads 234F. The two pressing portions 231F are located on opposite sides of the base 21F. Each pressing portion 231F is connected to one of the two resilient structures 232F. Each resilient structure 232F is connected to one of the two engaging heads 234F.

[0496] See Figure 54 The second fastener 2F may have a magnet receiving portion 216F. A second magnet 6F may be fixed in the magnet receiving portion 216F. Both the magnet receiving portion 216F and the second magnet 6F may be circular, but this application is not limited thereto. The base 21F may have a hole 215F. The hole 215F may be connected to a webbing to limit the position of the second fastener 2F relative to the webbing.

[0497] The base 21F may include a longitudinal guide rib 212F. The longitudinal guide rib 212F may be straight and extend in a direction perpendicular to the moving direction of the pressing part 231F (i.e., longitudinal Y). Both sides of the magnet receiving part 216F may have longitudinal guide ribs 212F. The longitudinal guide ribs 212F may connect the magnet receiving part 216F and the outer periphery of the base 21F. The longitudinal guide ribs 212F may gradually taper from the magnet receiving part 216F to the outer periphery of the base 21F, but this application is not limited thereto. The longitudinal guide ribs 212F on both sides of the magnet receiving part 216F are in a straight line. The longitudinal guide ribs 212F may be centrally located on the base 21F. One end of the elastic structure 232F away from the pressing part 231F may abut against the longitudinal guide rib 212F. The longitudinal guide rib 212F may include a first portion 2121F and a second portion 2122F. The thickness of the first part 2121F may be greater than the thickness of the second part 2122F, but this application is not limited thereto.

[0498] In one embodiment, the base 21F may include only one longitudinal guide rib 212F. That is, only one side of the magnet receiving portion 216F has the longitudinal guide rib 212F.

[0499] The base 21F may further include a transverse guide rib 213F and a guide block 214F. The transverse guide rib 213F may be straight. The magnet receiving portion 216F may have transverse guide ribs 213F on both sides. The transverse guide ribs 213F may connect to the magnet receiving portion 216F. The guide block 214F may be formed as a cylindrical protrusion, but this application is not limited thereto. In other embodiments, the guide block 214F may be formed as a square, rectangular, or other shaped protrusion. One side of the pressing portion 231F (the side facing the magnet receiving portion 216F) may have a guide arm 235F. The guide arm 235F may be located between the transverse guide rib 213F and the guide block 214F, such that the transverse guide rib 213F and the guide block 214F can restrict the direction of movement of the guide arm 235F. In other words, the distance between the transverse guide rib 213F and the guide block 214F is substantially equal to the width of the guide arm 235F. The transverse guide rib 213F may be perpendicular to the longitudinal guide rib 212F. In other words, the extending direction of the transverse guide rib 213F is the same as the movement direction of the pressing part 231F. The transverse guide rib 213F may include a third part 2131F and a fourth part 2132F. The thickness of the third part 2131F may be greater than the thickness of the fourth part 2132F, but this application is not limited thereto.

[0500] In this embodiment, each pressing part 231F may have two guide arms 235F parallel to each other. A transverse guide rib 213F may be located between the two guide arms 235F. The base 21F may include two guide blocks 214F. The two guide blocks 214F are located outside the two guide arms 235F.

[0501] In one embodiment, the base 21F may include only one lateral guide rib 213F. That is, the lateral guide rib 213F is only present on one side of the magnet receiving portion 216F.

[0502] In one embodiment, each pressing part 231F may have a guide arm 235F. The base 21F may include a guide block 214F.

[0503] See Figure 55 and Figure 56 The cover 22F may have a limiting rib 222F. The limiting rib 222F may project from the cover 22F toward the base 21F. The limiting rib 222F may have a straight shape. Alternatively, the limiting rib 222F may have a curved shape, a "T" shape, etc. The limiting rib 222F may restrict undesired movement of the resilient structure 232F and the engaging head 235F in the vertical direction Z. In this embodiment, the cover 22F may have four limiting ribs 222F. In other embodiments, the cover 22F may have one, two, six, eight, or other numbers of limiting ribs 222F.

[0504] The operation of the 100F fastener will be described below.

[0505] See Figures 55 to 57A When the first fastener 1F and the second fastener 2F are locked, the first fastener 1F engages with the second fastener 2F in the vertical direction Z. The locking part 12F of the first fastener 1F enters the receiving hole 211F of the second fastener 2F. The pushing ramp 121F on the locking part 12F pushes the engaging head 234F to move laterally away from the receiving hole 211F, allowing the locking part 12F to continue entering the second fastener 2F. During this process, the lateral movement of the engaging head 234F causes the engaging head connecting part 233F to deform. When the locking part 12F moves to the locking groove 122F and aligns with the engaging head 234F, the engaging head connecting part 233F returns to its undeformed state and pushes the engaging head 234F into the locking groove 122F, thereby engaging the engaging head 234F with the locking groove 122F. At this time, the first fastener 1F and the second fastener 2F are locked.

[0506] To unlock the first fastener 1F from the second fastener 2F, press the pressing portions 231F on both sides to move them toward the receiving hole 211F. This movement of the pressing portions 231F toward the receiving hole 211F causes the first section 2321F of the elastic structure 232F to move toward the receiving hole 211F. Because the elastic structure abuts against the protrusion 221F, the movement of the first section 2321F toward the receiving hole 211F causes the second section 2323F of the elastic structure 232F to move away from the receiving hole 211F. The engaging head 234F connected to the second section 2323F moves away from the receiving hole 211F along with the second section 2323F, thereby disengaging the engaging head 234F from the locking groove 122F. At this time, the locking part 12F is not locked by the engaging head 234F, so it can move in the opposite direction to the direction in which the engaging head 234F is inserted into the receiving hole 211F, thereby separating the first fastener 1F from the second fastener 2F.

[0507] In other embodiments, for example, the engaging head connection portion 233F is not elastic. During the process where the locking portion 12F of the first fastener 1F enters the receiving hole 211F of the second fastener 2F, and the pushing ramp 121F on the locking portion 12F pushes the engaging head 234F to move laterally away from the receiving hole 211F, the lateral movement of the engaging head 234F causes deformation of the elastic structure 232F (e.g., the second segment 2323F and the protrusion 2322F).

[0508] The twelfth embodiment of this application will be described below. The parts of the twelfth embodiment that are identical to those of the eleventh embodiment will be omitted to avoid repetition.

[0509] See Figure 57BThe protruding post 221F may include a protruding post body 2211F and a protruding post limiting portion 2212F. The protruding post body 2211F may be formed in a cylindrical shape, but this application is not limited thereto. In other embodiments, the protruding post body 2211F may be formed as a square, rectangular, or other shaped protrusion. The protruding post body 2211F may be disposed on the housing 20F. Specifically, the protruding post body 2211F may be disposed on the cover 22F and extend vertically in the Z direction from the cover 22F toward the base 21F. In another embodiment, the protruding post body 2211F may be disposed on the base 21F.

[0510] The protruding post limiting portion 2212F extends laterally from one end of the protruding post body 2211F to limit undesirable movement of the elastic structure 232F and the engaging head 235F in the vertical direction Z. The dimension of the protruding post body 2211F in the vertical direction Z can be greater than or equal to the sum of the dimensions of the first section 2321F and the protruding post limiting portion 2212F in the vertical direction Z. Since the elastic structure 232F can be limited at different positions by the protruding post limiting portion 2212F and the limiting rib 222F, the elastic structure 232F and the engaging head 235F will have better stability in the vertical direction Z.

[0511] For further details of the twelfth embodiment, please refer to the eleventh embodiment.

[0512] The thirteenth embodiment of this application will be described below. The parts of the thirteenth embodiment that are identical to those of the eleventh embodiment will be omitted to avoid repetition.

[0513] See Figure 58 The fastener 100F may include a first fastener 1F and a second fastener 2F. The first fastener 1F and the second fastener 2F can be interlocked. The first fastener 1F and the second fastener 2F can be locked or unlocked. The second fastener 2F may include a base 21F, a cover 22F, and a release assembly 23F disposed between the base 21F and the cover 22F. In this embodiment, the cover 22F may not include the protrusion 221F.

[0514] See Figures 59 to 61 The release assembly 23F may include a pressing portion 231F, an elastic structure 232F, and a locking head 234F. One end of the elastic structure 232F may be connected to the pressing portion 231F. The other end (terminal end) of the elastic structure 232F may be connected to the locking head 234F. The release assembly 23F includes a locking head connecting portion 233F. The locking head connecting portion 233F has a curved shape and connects the locking head 234F to the elastic structure 232F. The extending directions of the locking head connecting portion 233F and the locking head 234F may be perpendicular to the movement direction of the pressing portion 231F.

[0515] The release assembly 23F may further include an extension 236F. The extension 236F may be formed as a straight rod and connected to one end of the elastic structure 232F away from the pressing portion 231F. The extension 236F is adjacent to the engaging head 234F and the engaging head connecting portion 233F. The engaging head 234F may be located between the extension 236F and the pressing portion 231F.

[0516] The base 21F may include a longitudinal guide rib 212F. The longitudinal guide rib 212F may be straight and extend in a direction perpendicular to the direction of movement of the pressing portion 231F. The extension portion 236F may be parallel to and in contact with the longitudinal guide rib 212F.

[0517] The number of extensions 236F may be the same as the number of elastic structures 232F. In this embodiment, the release assembly 23F may include four extensions 236F.

[0518] In other embodiments, the release assembly 23F may include one, two, or other number of extensions 236F.

[0519] The operation of the 100F fastener will be described below.

[0520] See Figures 60 to 62 When the first fastener 1F and the second fastener 2F are locked, the first fastener 1F engages with the second fastener 2F from below. The locking portion 12F of the first fastener 1F enters the receiving hole 211F of the second fastener 2F. The pushing ramp 121F on the locking portion 12F pushes the engaging head 234F to move laterally away from the receiving hole 211F, allowing the locking portion 12F to continue entering the second fastener 2F. During this process, the lateral movement of the engaging head 234F causes the engaging head connecting portion 233F to deform. When the locking portion 12F moves to the locking groove 122F and aligns with the engaging head 234F, the engaging head connecting portion 233F returns to its undeformed state and pushes the engaging head 234F into the locking groove 122F, thereby engaging the engaging head 234F with the locking groove 122F. At this point, the first fastener 1F and the second fastener 2F are locked.

[0521] To unlock the first fastener 1F and the second fastener 2F, press the pressing portions 231F on both sides to move them toward the receiving hole 211F. This movement of the pressing portions 231F toward the receiving hole 211F causes the end of the elastic structure 232F connected to the pressing portion 231F to move. At this time, the end and extension 236F of the elastic structure 232F abut against the longitudinal guide rib 212F, causing the elastic structure 232F to deform. Simultaneously, the end and extension 236F of the elastic structure 232F slide outwards (along the longitudinal Y direction away from the receiving hole 211F) along the contact surface of the longitudinal guide rib 212F, thereby causing the engaging head 234F to disengage from the receiving hole 211F. At this time, since the locking part 12F is not locked by the locking head 234F, the locking part 12F can move in the opposite direction to the direction in which the locking part 12F is inserted into the receiving hole 211F, thereby realizing the separation of the first fastener 1F and the second fastener 2F.

[0522] For further details of the thirteenth embodiment, please refer to the eleventh embodiment.

[0523] In the embodiments of this application, the elastic structure has a longitudinal section (the first section 2321F in the eleventh and twelfth embodiments, or the extension 236F in the thirteenth embodiment) for abutting against the abutting portion (protrusion 221F or longitudinal guide rib 212F) on the housing 20F of the second fastener 2F when the pressing portion 231F of the second fastener 2F is operated, so that the operation in the lateral direction (the lateral displacement of the pressing portion 231F or the lateral displacement of the first end of the elastic structure 232F) is converted into the longitudinal displacement of the second end of the elastic structure 232F, or the operation in the lateral direction (the inward movement of the pressing portion 231F or the inward movement of the first end of the elastic structure 232F) is converted into the outward movement of the second end of the elastic structure 232F.

[0524] The first magnet 5F and the second magnet 6F magnetically attract or repel each other during the insertion of the first fastener 1F and the second fastener 2F. The first fastener 1F or the second fastener 2F also has a release mechanism (pressing part 231F) movably disposed thereon. When the release mechanism is operated to release the locking part (engaging head 234F) from the locking part 12F, allowing the first fastener 1F and the second fastener 2F to be pulled apart, the first magnet 5F and the second magnet 6F magnetically attract each other, keeping the first fastener 1F and the second fastener 2F in an inserted state; or, the first magnet 5F and the second magnet 6F magnetically repel each other, separating the first fastener 1F and the second fastener 2F.

[0525] In the embodiments of this application, when the release mechanism is operated to release the locking part (locking head 234F) from the locking part 12F to allow the first fastener 1F and the second fastener 2F to be pulled out of each other, the first magnet 5F and the second magnet 6F can maintain their relative positional relationship.

[0526] In the embodiments of this application, when the release mechanism is operated to release the locking part (locking head 234F) from the locking part 12F to allow the first fastener 1F and the second fastener 2F to be pulled out of each other, the first magnet 5F and the second magnet 6F can maintain alignment along the direction in which the first fastener 1F and the second fastener 2F are inserted into each other.

[0527] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the claims.

[0528] Although this application has been described with reference to exemplary embodiments, the terminology used is descriptive and exemplary, and not restrictive. Because this application can be embodied in many forms without departing from its spirit and essence, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted in the broadest possible sense within the scope defined by the claims. Therefore, all variations falling within the scope of the claims or their equivalents should be covered by the claims.
