The specific structure and operation means of the two-way separator 100 according to the embodiment of the disclosure will be described below with reference to FIG. 1 to FIG. 7, but the disclosure is not limited thereto.
[0025] Referring to FIG. 1 and FIG. 2, in the embodiment, the two-way separator 100 includes a pair of fastener stringers 110A and 110B and a pair of sliders 120A and 120B. The pair of fastener stringers 110A and 110B includes a pair of fastener tapes 112A and 112B extending in a front-rear direction X (corresponding to a length direction) and disposed opposite to each other in a left-right direction Y (corresponding to a width direction), a pair of element columns 114A and 114B arranged along the front-rear direction X on the pair of fastener tapes 112A and 112B and capable of engaging with or separating from each other, and a separable pin 116 and a retainer pin 118 respectively disposed at rear end portions of the pair of fastener tapes 112A and 112B. The pair of element columns 114A and 114B are, for example, disposed on a rear side of the pair of fastener tapes 112A and 112B. The separable pin 116 and the retainer pin 118 are, for example, disposed at ends of the pair of fastener tapes 112A and 112B through outer wing pieces 119 and are disposed at side edges of the pair of fastener tapes 112A and 112B to be located on a front side and a rear side (as shown in FIG. 1 and FIG. 2).
[0026] Furthermore, in the embodiment, as shown in FIG. 1 and FIG. 2, the pair of sliders 120A and 120B are disposed on the pair of fastener stringers 110A and 110B in a state where their tails are opposite to each other, and are capable of sliding along the fastener stringers 110A and 110B in the front-rear direction X with the front and rear directions in the front-rear direction X respectively as opening directions for opening the pair of fastener stringers 110A and 110B. Here, the tail refers to one end of each slider body 122 of the sliders 120A and 120B where no guide post is provided. The slider 120A disposed at the front in the front-rear direction X (i.e., the upper side in FIG. 1 and FIG. 2) is capable of sliding rearward (i.e., the lower side in FIG. 1 and FIG. 2) to open the pair of fastener stringers 110A and 110B (i.e., with the rearward as the opening direction), and the slider 120B disposed at the rear in the front-rear direction X is capable of sliding forward to open the pair of fastener stringers 110A and 110B (i.e., with the forward as the opening direction). Thus, the slider 120A is capable of opening the front side of the pair of fastener stringers 110A and 110B, and the slider 120B is capable of opening the rear side of the pair of fastener stringers 110A and 110B, thereby forming the two-way separator 100 (i.e., the pair of sliders 120A and 120B are capable of opening the pair of fastener stringers 110A and 110B from both the front side and the rear side of the pair of fastener stringers 110A and 110B).
[0027] Furthermore, in the embodiment, as shown in FIG. 1 and FIG. 2, in a situation where the pair of sliders 120A and 120B are located at the rear end portions (i.e., adjacent to the separable pin 116 and the retainer pin 118) of the pair of fastener tapes 112A and 112B and adjacent to each other in the front-rear direction X, the separable pin 116 and the retainer pin 118 are capable of being inserted into the pair of sliders 120A and 120B or being pulled out from the pair of sliders 120A and 120B. Specifically, the pair of sliders 120A and 120B each have a slider body 122 and a lock pin 126 that protrudes from a blade (for example, the upper blade 122a) of the slider body 122 into an internal element channel 124. The slider body 122 includes an upper blade 122a and a lower blade 122b that are opposite to each other and a guide post 122c disposed between the upper blade 122a and the lower blade 122b, and the element channel 124 is formed between the upper blade 122a and the lower blade 122b. FIG. 2 omits showing a part (for example, the lower blade 122b) of the slider body 122 of each of the pair of sliders 120A and 120B to facilitate showing the relative positions of the pair of element columns 114A and 114B and the separable pin 116 and retainer pin 118 that pass through the pair of sliders 120A and 120B. Moreover, the lock pin 126 of each of the sliders 120A and 120B may be operated in a manner where it is simultaneously driven by a pull tab (not shown) to move toward the blade of the slider body 122 (retract) during the process of the pull tab driving the sliders 120A and 120B to slide, and moves toward the element channel 124 (protrude/insert) when the pull tab is released after the sliders 120A and 120B slide to a fixed point. The disclosure does not limit the operation manner of the lock pin 126, which may be adjusted according to requirements.
[0028] Through the above arrangement, in the embodiment, in a situation where the pair of sliders 120A and 120B each slide rearward (i.e., toward the lower side of FIG. 2) to the rear end portions of the pair of fastener tapes 112A and 112B, the separable pin 116 and the retainer pin 118 are capable of being inserted into the element channels 124 of each of the pair of sliders 120A and 120B (as shown in FIG. 2). Correspondingly, in a situation where the pair of sliders 120A and 120B each slide forward (i.e., toward the upper side of FIG. 2) and leave the rear end portions of the pair of fastener tapes 112A and 112B, the separable pin 116 and the retainer pin 118 are capable of being pulled out from the element channels 124 of each of the pair of sliders 120A and 120B, and the pair of element columns 114A and 114B pass through the element channels 124 of each of the pair of sliders 120A and 120B, thereby enabling the pair of sliders 120A and 120B to slide on the pair of fastener stringers 110A and 110B to open or close the pair of fastener stringers 110A and 110B. During the sliding process of each of the pair of sliders 120A and 120B, the lock pin 126 of each of the pair of sliders 120A and 120B protrudes toward the element channel 124 (for example, moving/inserting toward the element channel 124 when the pull tab is released after the sliders 120A and 120B slide to a fixed point), thereby potentially protruding toward the separable pin 116 and the retainer pin 118 during the process of the pair of sliders 120A and 120B passing through the separable pin 116 and the retainer pin 118. Therefore, the two-way separator 100 of the embodiment improves the structure of the separable pin 116 to avoid collision between the lock pin 126 and the separable pin 116 that extends further forward in the front-rear direction X compared to the retainer pin 118.
[0029] In detail, in the embodiment, as shown in FIG. 2 to FIG. 5, the separable pin 116 has a separable pin body 116a, a separable pin protrusion 116b protruding from the separable pin body 116a toward the retainer pin 118, and a groove 116c located at the rear end of the separable pin protrusion 116b. The retainer pin 118 has a retainer pin body 118a and a retainer pin protrusion 118b protruding from the retainer pin body 118a toward the separable pin 116 and engaging with the groove 116c. As an example, the separable pin body 116a and the retainer pin body 118a are, for example, a pair of rod-like structures that extend substantially in the front-rear direction X (corresponding to the length direction) and are arranged side by side in the left-right direction Y (corresponding to the width direction). Moreover, the separable pin protrusion 116b and the retainer pin protrusion 118b respectively extend toward opposite directions and are located between the separable pin body 116a and the retainer pin body 118a, and are staggered in the front-rear direction X, thereby enabling the retainer pin protrusion 118b to engage with the groove 116c located at the rear end of the separable pin protrusion 116b (as shown in FIG. 4 and FIG. 5).
[0030] Furthermore, in the embodiment, as shown in FIG. 3 to FIG. 7, the separable pin protrusion 116b has a half tooth portion 116b1 and a tilt portion 116b2 located on an upper side (i.e., front side) of the half tooth portion 116b1. That is, the separable pin protrusion 116b has different shapes with the tilt portion 116b2 formed on the front side (as shown in FIG. 4 and FIG. 6) and the half tooth portion 116b1 formed on the back side (as shown in FIG. 5 and FIG. 7), and the half tooth portion 116b1 and the tilt portion 116b2 are integrally formed in an up-down direction Z (corresponding to the thickness direction) to form the separable pin protrusion 116b. Thus, the half tooth portion 116b1 of the separable pin protrusion 116b may correspond to the element of the element column 114B near the retainer pin 118 on the back side (as shown in FIG. 5), and the tilt portion 116b2 of the separable pin protrusion 116b may contact the retainer pin protrusion 118b on the front side (as shown in FIG. 3 and FIG. 4).
[0031] Furthermore, in the embodiment, as shown in FIG. 3, FIG. 4, and FIG. 6, the tilt portion 116b2 has a tilt surface 116b3 that tilts from an upper surface 116a1 of the separable pin body 116a (i.e., the surface on the front side, corresponding to the upper side in the up-down direction Z) toward a projecting side edge 116e1 of the half tooth portion 116b1 and tilts from the upper side toward the lower side (corresponding to from the front side toward the back side) in the up-down direction Z (corresponding to the thickness direction), and a dimension D1 (corresponding to thickness/depth) of the tilt portion 116b2 in the up-down direction Z is greater than a protrusion amount T of the lock pin 126 protruding from the blade (for example, the upper blade 122a) into the element channel 124 in the up-down direction Z. When there is a gap (as shown in FIG. 3) between the topmost surface (i.e., the uppermost surface in the up-down direction Z) of the tilt portion 116b2 and the bottommost surface (i.e., the lowermost surface in the up-down direction Z) of the blade (for example, the upper blade 122a), the dimension D1 of the tilt portion 116b2 in the up-down direction Z is not limited to the distance from the bottommost surface of the tilt portion 116b2 (i.e., the lowermost surface in the up-down direction Z) to the topmost surface of the tilt portion 116b2, but may also refer to the distance from the bottommost surface of the tilt portion 116b2 to the bottommost surface of the blade (for example, the upper blade 122a). Correspondingly, the protrusion amount T of the lock pin 126 may refer to the distance from the bottommost surface of the lock pin 126 (i.e., the lowermost surface in the up-down direction Z) to the bottommost surface of the blade (for example, the upper blade 122a). That is, the dimension D1 of the tilt portion 116b and the protrusion amount T of the lock pin 126 may be set with the bottommost surface of the blade (for example, the upper blade 122a) as the same reference. Thus, as shown in FIG. 3, the separable pin protrusion 116b may maintain a high contact area between the separable pin protrusion 116b and the retainer pin protrusion 118b through the tilt portion 116b2 having a large dimension D1 (thickness), and may avoid the lock pins 126 of the sliders 120A and 120B through the tilt portion 116b2 having a large dimension D1 (depth). Accordingly, the two-way separator 100 may balance the high contact area of the separable pin protrusion 116b and the retainer pin protrusion 118b and avoid interference of the lock pins 126 of the sliders 120A and 120B.
[0032] Furthermore, in the embodiment, as shown in FIG. 3 and FIG. 6, the tilt surface 116b3 of the tilt portion 116b2 includes a curved surface. As an example, the tilt surface 116b3 of the tilt portion 116b2 includes a first curved surface 116s1 and a second curved surface 116s2 that are connected to each other, and the curvature (e.g., radius of curvature) of the first curved surface 116s1 is different from the curvature (e.g., radius of curvature) of the second curved surface 116s2. Therefore, as shown in FIG. 3, the tilt surface 116b3 forms an outwardly protruding turning point 116s3 between the first curved surface 116s1 and the second curved surface 116s2 that are recessed inward. Thus, the tilt surface 116b3 may avoid interference of the lock pins 126 of the sliders 120A and 120B through the recess of the second curved surface 116s2 that is closer to the projecting side edge 116e1 of the half tooth portion 116b1, and may increase the contact area between the separable pin protrusion 116b and the retainer pin protrusion 118b through the protruding of the turning point 116s3 formed between the first curved surface 116s1 and the second curved surface 116s2. However, in other embodiments not shown, the tilt surface 116b3 of the tilt portion 116b2 may also include a single curved surface, or may include multiple planes facing different directions and connected to each other. The disclosure is not limited thereto and may be adjusted according to requirements.
[0033] Furthermore, in the embodiment, as shown in FIG. 3 and FIG. 6, a connecting edge 116e2 of the tilt portion 116b2 connected to the half tooth portion 116b1 is spaced apart from the projecting side edge 116e1 of the half tooth portion 116b1 by an interval to form a platform portion 116d on the upper side (i.e., front side) of the half tooth portion 116b1. That is, the tilt portion 116b2 extends from the upper surface 116a1 of the separable pin body 116a toward the projecting side edge 116e1 of the half tooth portion 116b1, but does not contact the projecting side edge 116e1, so that the connecting edge 116e2 of the tilt portion 116b2 retracts inward relative to the projecting side edge 116e1, thereby forming the platform portion 116d on the upper side of the half tooth portion 116b1. Thus, the tilt portion 116b2 is offset more toward the separable pin body 116a direction compared to the half tooth portion 116b1, thereby enabling avoidance of interference with the lock pins 126 of the sliders 120A and 120B. In addition, as shown in FIG. 3, the dimension D1 (corresponding to thickness/depth) of the tilt portion 116b2 in the up-down direction Z is greater than a dimension D2 (corresponding to thickness) of the half tooth portion 116b1 in the up-down direction Z, so that the tilt portion 116b2 may further avoid interference with the lock pins 126 of the sliders 120A and 120B. Moreover, a dimension D3 (corresponding to thickness) of the retainer pin protrusion 118b in the up-down direction Z is equal to a dimension (corresponding to thickness) of the separable pin protrusion 116b in the up-down direction Z, which is the sum of the dimension D1 of the tilt portion 116b2 and the dimension D2 of the half tooth portion 116b1, thereby enabling an increase the contact area between the retainer pin protrusion 118b and the separable pin protrusion 116b.
[0034] However, in other embodiments not shown, the tilt portion 116b2 may also further extend to the projecting side edge 116e1 of the half tooth portion 116b1 (i.e., the connecting edge 116e2 of the tilt portion 116b2 contacts the projecting side edge 116e1), while omitting the setting of the platform portion 116d. Similarly, the tilt portion 116b2 is not limited to extending from the upper surface 116a1 of the separable pin body 116a, but may also be spaced apart from the upper surface 116a1 of the separable pin body 116a by an interval, and extend in a tilting manner from a portion on the side wall of the separable pin body 116a that is lower than the upper surface 116a1 toward the projecting side edge 116e1 of the half tooth portion 116b1. In addition, the dimension D1 of the tilt portion 116b2 in the up-down direction Z is not limited to being greater than the dimension D2 of the half tooth portion 116b1 in the up-down direction Z, and the dimension D3 of the retainer pin protrusion 118b in the up-down direction Z is not limited to being equal to the dimension of the separable pin protrusion 116b in the up-down direction Z (i.e., the sum of the dimension D1 of the tilt portion 116b2 and the dimension D2 of the half tooth portion 116b1), as long as the tilt surface 116b3 of the tilt portion 116b2 tilts from the upper surface 116a1 of the separable pin body 116a toward the projecting side edge 116e1 of the half tooth portion 116b1 and tilts from the upper side to the lower side, and the dimension D1 of the tilt portion 116b2 is greater than the protrusion amount T of the lock pin 126. The specific structures of the half tooth portion 116b1, tilt portion 116b2, tilt surface 116b3, etc. of the separable pin protrusion 116b described above may be adjusted according to requirements, and the disclosure is not limited thereto.
[0035] Additionally, in the embodiment, as shown in FIG. 6 and FIG. 7, the half tooth portion 116b1 includes a connecting portion 116p1 connected with the separable pin body 116a, and a head portion 116p2 protruding forward from the front end of the connecting portion 116p1 (the end toward the element column 114A), and a dimension L1 (corresponding to length) of the tilt portion 116b2 in the front-rear direction X does not exceed a dimension L2 (corresponding to length) of the connecting portion 116p1 in the front-rear direction X. That is, the front end of the tilt portion 116b2 (the end toward the element column 114B) does not exceed the front end of the connecting portion 116p1 in the front-rear direction X, so that in the state of viewing the half tooth portion 116b1 from the back side (as shown in FIG. 7), the tilt portion 116b2 is hidden behind the half tooth portion 116b1 and does not protrude between the connecting portion 116p1 and the head portion 116p2 of the half tooth portion 116b1. Thus, the setting of the tilt portion 116b2 does not interfere with the engaging action between the half tooth portion 116b1 and the element of the opposite element column 114B.
[0036] Furthermore, in the embodiment, as shown in FIG. 6, the front edge of the tilt portion 116b2 in the front-rear direction X (the edge toward the element column 114A) has a chamfer 116r. Therefore, when the sliders 120A and 120B slide on the fastener stringers 110A and 110B and pass through the separable pin 116 (the separable pin 116 is inserted into the sliders 120A and 120B), even if the separable pin 116 and the retainer pin 118 are not yet completely engaged during the operation process (the state shown in FIG. 2) and the lock pins 126 of the sliders 120A and 120B unintentionally contact the front edge of the tilt portion 116b2 of the separable pin protrusion 116b of the separable pin 116, the lock pins 126 are not easily damaged by contacting the front edge of the tilt portion 116b2 having the chamfer 116r. That is, the setting of the chamfer 116r may avoid the lock pins 126 from breaking due to contact with the front edge of the tilt portion 116b2. However, in other embodiments not shown, the setting of the chamfer 116r may also be omitted, as long as the dimension D1 (corresponding to thickness/depth) of the tilt portion 116b2 is greater than the protrusion amount T of the lock pins 126. Additionally, when the sliders 120A and 120B slide on the fastener stringers 110A and 110B and leave the separable pin 116 (the separable pin 116 is pulled out from the sliders 120A and 120B), the separable pin 116 and the retainer pin 118 are in an engaged state, and there is no concern that the lock pins 126 of the sliders 120A and 120B will unintentionally contact the rear edge of the tilt portion 116b2 of the separable pin protrusion 116b of the separable pin 116. Therefore, no chamfer is provided at the rear edge of the tilt portion 116b2, but in other embodiments not shown, a chamfer may also be provided at the rear edge of the tilt portion 116b2. The disclosure is not limited thereto and may be adjusted according to requirements.
[0037] In summary, in the two-way separator of the disclosure, the separable pin has a separable pin body, a separable pin protrusion protruding from the separable pin body, and a groove located at the rear end of the separable pin protrusion, and the retainer pin has a retainer pin body and a retainer pin protrusion protruding from the retainer pin body and engaging with the groove. The separable pin protrusion has a half tooth portion and a tilt portion located on an upper side (i.e., front side) of the half tooth portion, the tilt portion has a tilt surface that tilts from an upper surface of the separable pin body toward a projecting side edge of the half tooth portion and tilts from an upper side toward a lower side (corresponding to from the front side toward the rear side) in the up-down direction (corresponding to thickness direction), and a dimension (corresponding to thickness/depth) of the tilt portion in the up-down direction is greater than the protrusion amount of the lock pin protruding from the blade into the element channel in the up-down direction. Thus, the separable pin protrusion may maintain a high contact area between the separable pin protrusion and the retainer pin protrusion through the tilt portion having a large dimension (thickness), and may avoid the lock pin of the slider through the tilt portion having a large dimension (depth). Preferably, the tilt surface of the tilt portion includes a curved surface, such as including a first curved surface and a second curved surface that are connected to each other and have different curvatures, thereby enabling further improvement of the high contact area between the separable pin protrusion and the retainer pin protrusion. Accordingly, the two-way separator of the disclosure may balance the high contact area of the separable pin protrusion and the retainer pin protrusion and avoid interference of the lock pin of the slider.
