Description
GENERAL STATE OF THE TECHNOLOGY Technical field
[0001] The disclosure relates to a technology in the field of zippers and specifically to a two-way separating element. Description of the state of the art
[0002] General zippers have a pair of closure strands, consisting of a pair of zipper tapes and a pair of element bars arranged on the zipper tapes, and a slider located on the closure strands which opens or closes the element bars by sliding, thereby engaging or separating the element bars, thus opening or closing the zipper chain formed by the pair of closure strands.A two-way separating element refers to the mounting of a pair of sliders in such a way that their ends are opposite each other, onto a pair of closure strands, such that the pair of sliders can slide along the closure strands in a forward-backward direction, the forward and backward directions in the forward-backward direction (corresponding to the longitudinal direction) each representing the opening direction for opening the closure strands. Furthermore, the pair of closure strands may also include a releasable pin and a retaining pin, each configured as open parts at the rear end sections of the pair of zipper strands.In a state where the releasable pin and the retaining pin are connected (for example, when at least part of the releasable pin is inserted into the retaining pin), the rear end sections of the pair of locking strands are closed by the releasable pin and the retaining pin, allowing them to serve as endpoints when the pair of sliders slides rearward on the pair of locking strands in the forward-backward direction.
[0003] In the prior art, to avoid situations where the slide travels too far when crossing the releasable pin and the retaining pin, there is a tendency to enlarge the contact area between a projection of the releasable pin and a projection of the retaining pin when the releasable pin and the retaining pin are connected. However, if the slide has a locking pin that projects from a wing of the slide body toward an internal element channel, the locking pin may then, when the slide crosses the releasable pin and the retaining pin, collide with the projection of the releasable pin or the projection of the retaining pin with the enlarged contact area, potentially causing damage to the projection of the releasable pin or the projection of the retaining pin.
[0004] Therefore, it is necessary to improve the design of the two-way separating element in order to compensate for the large contact area of the projection of the releasable pin and the projection of the retaining pin and to avoid a collision with the locking pin of the slide. SUMMARY
[0005] The disclosure provides a two-way separating element that can compensate for the large contact area of the projection of the releasable pin and the projection of the retaining pin and can avoid a collision with the locking pin of the slide.
[0006] The disclosure provides a two-way separating element comprising a pair of closure strands with a pair of zipper tapes extending in a forward-backward direction and arranged opposite each other in a left-right direction, a pair of element rails arranged along the forward-backward direction on the pair of zipper tapes and capable of engaging or disengaging each other, and a releasable pin and a retaining pin, each located at the rear end sections of the pair of zipper tapes; and a pair of sliders arranged on the pair of closure strands in a state where their rear ends are opposite each other and capable of sliding along the closure strands in the forward-backward direction.wherein the forward and reverse directions in the forward-reverse direction each represent the opening direction for opening the pair of closure strands. When the pair of sliders is positioned adjacent to each other at the rear end sections of the pair of zipper tapes and in the forward-reverse direction, the release pin and retaining pin can be inserted into or removed from the pair of sliders. The pair of sliders each has a slider body and a retaining pin projecting from a wing of the slider body toward an inner element channel. The release pin has a release pin body, a release pin projection projecting from the release pin body toward the retaining pin, and a recess located at a rear end of the release pin projection. The retaining pin has a retaining pin body and a retaining pin projection.the projection of the releasable pin extends from the retaining pin body towards the releasable pin and engages with the recess. The projection of the releasable pin has a semi-toothed section and an inclined section located on a top surface of the semi-toothed section. The inclined section has an inclined surface inclined from a top surface of the releasable pin body to a projecting lateral edge of the semi-toothed section and inclined in an upward-downward direction from a top surface to a bottom surface. One dimension of the inclined section in the upward-downward direction is greater than the extent of the projection of the retaining pin extending from the wing in the upward-downward direction into the element channel.
[0007] In one embodiment of the two-way separating element of the disclosure, the inclined surface of the inclined section has a curved surface.
[0008] In one embodiment of the two-way separating element of the disclosure, the inclined surface of the inclined section has a first curved surface and a second curved surface connected to each other, and a curvature of the first curved surface differs from a curvature of the second curved surface.
[0009] In one embodiment of the two-way separating element of the disclosure, the half-tooth section has a connecting section that is connected to the body of the releasable pin and a head section that projects forward from a front end of the connecting section, and one dimension of the inclined section in the forward-backward direction does not exceed one dimension of the connecting section in the forward-backward direction.
[0010] In one embodiment of the two-way separating element of the disclosure, a front end edge of the inclined section has a chamfer in the forward-backward direction.
[0011] In one embodiment of the two-way separating element of the disclosure, a dimension of the retaining pin projection in the upward-downward direction is equal to a dimension of the projection of the releasable pin in the upward-downward direction.
[0012] In one embodiment of the two-way separating element of the disclosure, a dimension of the inclined section in the upward-downward direction is larger than a dimension of the half-tooth section in the upward-downward direction.
[0013] In one embodiment of the two-way separating element of the disclosure, a connecting edge of the inclined section, which is connected to the half-tooth section, is spaced apart from the projecting side edge of the half-tooth section, so that a platform section is formed on a top side of the half-tooth section.
[0014] Based on the above, the releasable pin in the two-way separating element of the disclosure has a releasable pin body, a releasable pin projection projecting from the releasable pin body, and a recess located at a rear end of the releasable pin projection. The retaining pin has a retaining pin body and a retaining pin projection projecting from the retaining pin body and engaging with the recess. The releasable pin projection has a semi-toothed section and an inclined section located on a top surface (i.e.,, a front side) of the half-tooth section, the inclined section has an inclined surface inclined from an upper surface of the body of the releasable pin to a projecting lateral edge of the half-tooth section and inclined in the upward-downward direction (corresponding to a thickness direction) from a top to a bottom (corresponding to the front to the back), and a dimension of the inclined section in the upward-downward direction (corresponding to the thickness / depth) is greater than an extent of the projection of the locking pin projecting from the wing in the upward-downward direction into the element channel.This allows the projection of the releasable pin to maintain a large contact area between the projection of the releasable pin and the retaining pin projection via the inclined section with its large dimension (thickness), and to avoid the locking pin of the slide valve via the inclined section with its large dimension (depth). Accordingly, the two-way separating element of the disclosure can compensate for the large contact area of the projection of the releasable pin and the retaining pin projection and prevent a collision with the locking pin of the slide valve.

Fig. Figure 5 is a schematic top view of a rear side of a pair of locking strands of the two-way separator, which is located in Fig. 1 is shown. Fig. Figure 6 is a schematic perspective view of the front of the locking mechanism with a releasable pin that is in Fig. 4 is shown. Fig. Figure 7 is a schematic perspective view of the reverse side of the locking mechanism with a releasable pin that is in Fig. Figure 5 shows the specific construction and operating equipment of the two-way separating element 100 according to the embodiment of the disclosure. Fig. 1 to Fig. 7 are described, but the revelation is not limited to that.
[0017] With reference to Fig. 1 and Fig. In embodiment 2, the two-way separating element 100 has a pair of locking strands 110A and 110B and a pair of slides 120A and 120B. The pair of closure strands 110A and 110B comprises a pair of zipper tapes 112A and 112B extending in a forward-backward direction X (corresponding to a longitudinal direction) and arranged opposite each other in a left-right direction Y (corresponding to a width direction), a pair of element rails 114A and 114B arranged along the forward-backward direction X on the pair of zipper tapes 112A and 112B, which can engage with each other or separate from each other, and a releasable pin 116 and a retaining pin 118, each arranged at the rear end sections of the pair of zipper tapes 112A and 112B.The pair of element rails 114A and 114B is, for example, arranged on a back side of the pair of zipper tapes 112A and 112B. The releasable pin 116 and the retaining pin 118 are, for example, arranged through outer wing sections 119 at the ends of the pair of zipper tapes 112A and 112B and are positioned on side edges of the pair of zipper tapes 112A and 112B such that they are located on a front and a back side (as in ). Fig. 1 and Fig. 2 is shown).
[0018] Furthermore, in this embodiment, the pair of sliders 120A and 120B is as shown in Fig. 1 and Fig. 2 shown in a state arranged on the pair of locking rods 110A and 1120B in which their rear ends are opposite each other, and can slide along the locking rods 110A and 1120B in the forward-backward direction X, with the forward and reverse directions in the forward-backward direction X respectively representing the opening direction for opening the pair of locking rods 110A and 1120B. Here, the rear end refers to an end of each slide body 122 of the slides where no guide column is provided. The slide 122A, which is at the front (i.e., at the top) in the forward-backward direction X Fig. 1 and Fig. 2) is arranged, can be reversed (i.e., towards the bottom in Fig. 1 and Fig. 2) slide to open the pair of locking strands 110A and 110B (i.e., the reverse direction represents the opening direction), and the slider 120B, which is located at the rear in the forward-backward direction X, can slide forward to open the pair of locking strands 110A and 110B (i.e., the forward direction represents the opening direction). This allows the slide 120A to open the front side of the pair of locking rods 110A and 110B and the slide 120B to open the rear side of the pair of locking rods 110A and 110B, thus forming the two-way separating element 100 (i.e., the pair of slides 120A and 120B can open the pair of locking rods 110A and 110B from both the front side and the rear side of the pair of locking rods 110A and 110B).
[0019] Moreover, in the embodiment as in Fig. 1 and Fig. Figure 2 shows that the releasable pin 116 and the retaining pin 118 are inserted into or removed from the pair of sliders 120A and 120B when the pair of sliders 120A and 120B are located at the rear end sections of the pair of zipper tapes 112A and 112B (i.e., next to the releasable pin 116 and the retaining pin 118) and are positioned side by side in the forward-backward direction X. Specifically, each pair of sliders 120A and 120B has a slider body 122 and a locking pin 126 that projects from a wing (for example, the upper wing 122a) of the slider body 122 into an inner element channel 124.The sliding body 122 has an upper wing 122a and a lower wing 122b, which are opposite each other, and a guide column 122c, which is arranged between the upper wing 122a and the lower wing 122b, and the element channel 124 is formed between the upper wing 122a and the lower wing 122b. Fig. 2 The representation of a part of the slide body 122 (for example, the lower wing 122a) of each of the pair of slides 120A and 120B was omitted in order to simplify the representation of the relative positions of the pair of element rails 114A and 114B and the releasable pin 116 and the retaining pin 118 passing through the pair of slides 120A and 120B. Furthermore, the locking pin 126 of each of the slides 120A and 120b can be actuated in such a way that it is simultaneously driven by a pull tab (not shown) so that during the process in which the pull tab drives the slides 120A and 120B in a sliding manner, it moves (retracts) towards the wing of the slide body 122 and, when the pull tab is released after the slides 120A and 120B have slid to a fixed point, moves (projects / penetrates) towards the element channel 124.The disclosure does not restrict the operation of the safety pin; it can be adapted as needed.
[0020] In the embodiment, the above arrangement allows the releasable pin 116 and the retaining pin 118 to be removed when the pair of sliders 120A and 120B are each moved backwards (i.e., to the lower side of Fig. 2) slides to the rear end sections of the pair of zipper tapes 112A and 112B, into which element channels 124 of each from the pair of sliders 120A and 120B are inserted (as in Fig. 2 is shown). Accordingly, the releasable pin 116 and the retaining pin 118 can then, when the pair of sliders 120A and 120B are each moved forward (i.e., to the upper side of Fig. 2) slides and exits the rear end sections of the pair of zipper tapes 112A and 112B, is pulled out of the element channels 124 of the pair of sliders 120A and 120B, and the pair of element rails 114A and 114B passes through the element channels 124 of each of the pair of sliders 120A and 120B, thus enabling the pair of sliders 120A and 120B to slide on the pair of closure strands 110A and 110B and to open the pair of closure strands 110A and 110B. During the sliding process of each of the pair of sliders 120A and 120B, the locking pin 126 of each of the pair of sliders 120A and 120B projects towards the element channel 124 (for example, by moving towards the element channel). 124 moves / enters this when the pull tab is released after the slides 120A and 120B have slid to a fixed point),so that, during the movement of the pair of sliders 120A and 120B over the releasable pin 116 and the retaining pin 118, it potentially protrudes towards the releasable pin 116 and the retaining pin 118. Therefore, the two-way separating element 100 of the embodiment improves the design of the releasable pin to avoid a collision between the locking pin 126 and the releasable pin 116, which extends further forward in the forward-backward direction X compared to the retaining pin 118.
[0021] In more detail, the embodiment as described in Fig. 2 to Fig. Figure 5 shows the releasable pin 116 comprising a body 116a of the releasable pin, a projection 116b of the releasable pin that extends from the body 116a of the releasable pin towards the retaining pin 118, and a recess 116c located at the rear end of the projection 116b of the releasable pin. The retaining pin 118 has a retaining pin body 118a and a retaining pin projection 118b that extends from the retaining pin body 118a towards the releasable pin 116 and engages with the recess 116c. As an example, the body 116a of the releasable pin and the retaining pin body 118a are a pair of rod-like structures that extend essentially in the forward-backward direction X (which corresponds to the longitudinal direction) and are arranged side by side in the left-right direction Y (which corresponds to the width direction).Moreover, the projection 116b of the releasable pin and the retaining pin projection 118b extend in opposite directions and are located between the body 116a of the releasable pin and the retaining pin body 118a and are offset in the forward-backward direction X, allowing the retaining pin projection 118b to engage with the recess 116c located at the rear end of the projection 116b of the releasable pin (as shown in . Fig. 4 and Fig. 5 is shown).
[0022] Furthermore, in the embodiment as described in Fig. 3 to Fig. Figure 7 shows that the projection 116b of the releasable pin has a semi-toothed section 116b1 and an inclined section 116b2, which is located on a top side (i.e., the front side) of the semi-toothed section 116b1. That is, the projection 116b of the releasable pin has different shapes, with the inclined section 116b2 being formed on the front side (as shown in Figure 7). Fig. 4 and Fig. 6 is shown) and the semi-tooth section 116b1 is formed on the back (as in Fig. 5 and Fig. 7) and the half-tooth section 116b1 and the inclined section 116b2 are formed in an upward-downward direction Z (corresponding to the thickness direction) in one unit to form the projection 116b of the releasable pin. Therefore, the half-tooth section 116b1 of the projection 116b of the releasable pin on the rear side can correspond to the element of the element rail 114B near the retaining pin 118 (as shown in Fig. 5) and the inclined section 116b2 of the projection 116b of the releasable pin on the front side can come into contact with the retaining pin projection 118b (as shown in Fig. 3 and Fig. 4 is shown).
[0023] Furthermore, in the embodiment as described in Fig. 3, Fig. 4 and Fig. Figure 6 shows the inclined section 116b2 forming an inclined surface 116b3, which is inclined from an upper surface 116a1 of the body 116a of the releasable pin (i.e., the surface on the front, corresponding to the top in the upward-downward direction Z) to a projecting side edge 116e1 of the half-tooth section 116b1 and is inclined in the upward-downward direction Z (corresponding to the thickness direction) from the top to the bottom (corresponding to the front to the back), and is a dimension D1 (corresponding to the thickness / depth) of the inclined section 116b2 in the upward-downward direction Z greater than an extent T of the projection of the locking pin 126, which projects from the wing (for example, the lower wing 112a) in the upward-downward direction Z into the element channel 124. If between the uppermost surface (i.e., the uppermost surface in the upward-downward direction Z) of the inclined section 116b2 and the lowermost surface (i.e., the lowest surface in the upward-downward direction Z) of the wing (for example, the upper wing 122a) has a gap (as in . Fig. As shown in Figure 3, the dimension D1 of the inclined section 116b2 in the upward-downward direction Z is not limited to the distance from the lowest surface of the inclined section 116b2 (i.e., the lowest surface in the upward-downward direction Z) to the uppermost surface of the inclined section 116b2, but can also refer to the distance from the lowest surface of the inclined section 116b2 to the lowest surface of the wing (for example, the upper wing 122a). Similarly, the extent T of the projection of the locking pin 126 can refer to the distance from the lowest surface of the locking pin 126 (i.e., the lowest surface in the upward-downward direction Z) to the lowest surface of the wing (for example, the upper wing 122a).This means that the dimension D1 of the inclined section 116b2 and the extent T of the projection of the locking pin 126 can be defined using the lowest surface of the wing (for example, the upper wing 122a) as the same reference. Therefore, the projection 116b of the releasable pin can be defined as shown in . Fig. Figure 3 shows that the inclined section 116b2, which has a large dimension D1 (thickness), maintains a large contact area between the projection 116b of the release pin and the retaining pin projection 118b, and, due to the inclined section 116b2 with a large dimension D1 (depth), avoids the locking pin 126 of the slides 120A and 120B. Accordingly, the two-way separating element 100 can compensate for the large contact area of the projection 116b of the release pin and the retaining pin projection 118b and avoid a collision with the locking pins 126 of the slides 120A and 120B.
[0024] Furthermore, in the embodiment as described in Fig. 3 and Fig. Figure 6 shows that the inclined surface 116b3 of the inclined section 116b2 is a curved surface. As an example, the inclined surface 116b3 of the inclined section 116b2 has a first curved surface 116s1 and a second curved surface 116s2 connected to each other, where the curvature (e.g., the radius of curvature) of the first curved surface 116s1 differs from the curvature (e.g., the radius of curvature) of the second curved surface 116s2. Therefore, the inclined surface 116b3 forms, as shown in Fig. Figure 3 shows an outwardly projecting inflection point 116s3 between the first curved surface 116s1 and the second curved surface 116s2, which are recessed inwards. Thus, the inclined surface 116b3, by means of the recess of the second curved surface 116s2, which is closer to the projecting side edge 116e1 of the half-tooth section 116b1, can avoid a collision with the locking pin 126 of the slides 120A and 120B, and, by means of the projection of the inflection point 116s3, which is formed between the first curved surface 116s1 and the second curved surface 116s2, the contact area between the projection 116b of the releasable pin and the retaining pin projection 116s1 is increased. However, in other embodiments not shown, the inclined surface 116b3 of the inclined section 116b2 may also have a single curved surface or several planes facing in different directions and connected to each other.The revelation is not limited to this and can be adapted as needed.
[0025] Furthermore, in the embodiment as in Fig. 3 and Fig. Figure 6 shows a connecting edge 116e2 of the inclined section 116b2, which is connected to the half-tooth section 116b1, spaced a distance from the projecting side edge 116e1 of the half-tooth section 116b1, so that a platform section 116d is formed on the top (i.e., the front) of the half-tooth section 116b1. That is, the inclined section 116b2 extends from the upper surface 116a1 of the body 116a of the detachable pin to the projecting side edge 116e1 of the half-tooth section 116b1, but is not in contact with the projecting side edge 116e1, so that the connecting edge 116e2 of the inclined section 116b2 is set back inwards with respect to the projecting side edge 116e1, forming the platform section 116d on the upper side of the half-tooth section 116b1.Therefore, the inclined section 116b2 is offset further towards the body 116a of the releasable pin compared to the half-tooth section 116b1, thus preventing a collision with the locking pins 126 of the slides 120A and 120B. Furthermore, as in . Fig. Figure 3 shows the dimension D1 (which corresponds to the thickness / depth) of the inclined section 116b2 in the upward-downward direction Z larger than a dimension D2 (which corresponds to the thickness) of the half-tooth section 116b1 in the upward-downward direction Z, so that the inclined section 116b2 can further avoid a collision with the locking pins 126 of the slides 120A and 120B. Moreover, a dimension D3 (corresponding to the thickness) of the retaining pin projection 118b in the upward-downward direction Z is equal to a dimension (corresponding to the thickness) of the projection 116b of the releasable pin in the upward-downward direction Z, which is the sum of the dimension D1 of the inclined section 116b2 and the dimension D2 of the half-tooth section 116b1, thereby enabling an increase in the contact area between the retaining pin projection 118b and the projection 116b of the releasable pin.
[0026] However, in other embodiments, which are not shown, the inclined section 116b2 can also extend further towards the projecting side edge 116e1 of the half-tooth section 116b1 (i.e., the connecting edge 116e2 of the inclined section 116b2 is in contact with the projecting side edge 116e1) and the setup of the platform section 116d is dispensed with. Likewise, the inclined section 116b2 is not limited to extending from the upper surface 116a1 of the body 116a of the releasable pin, but can also be spaced a distance from the upper surface 116a1 of the body 116a of the releasable pin and extend in an inclined manner from a section on the side wall of the body 116a of the releasable pin, which is lower than the upper surface 116a1, to the projecting side edge 116e1 of the half-tooth section 116b1.Furthermore, the dimension D1 of the inclined section 116b2 in the upward-downward direction Z is not limited to being larger than the dimension D2 of the half-tooth section 116b1 in the upward-downward direction Z, and the dimension D3 of the retaining pin projection 118b in the upward-downward direction Z is not limited to being equal to the dimension of the projection 116b of the releasable pin in the upward-downward direction Z (i.e., the sum of the dimension D1 of the inclined section 116b2 and the dimension D2 of the half-tooth section 116b1), as long as the inclined surface 116b3 of the inclined section 116b2 slopes from the upper surface 116a1 of the body 116a of the releasable pin towards the projecting side edge 116e1 of the half-tooth section 116b1 and inclined from the top to the bottom and the dimension D1 of the inclined section 116b2 is larger than the extent T of the projection of the locking pin 126.The specific configurations of the half-tooth section 116b1, the inclined section 116b2, the inclined surface 116b3, etc., of the projection 116b of the detachable pin described above can be adapted as needed, and the disclosure is not limited thereto.
[0027] Furthermore, in the embodiment as in Fig. 6 and Fig. Figure 7 shows the half-tooth section 116b1 comprising a connecting section 116p1, which is connected to the body 116a of the detachable pin, and a head section 116p2, which projects forward from the front end of the connecting section 116p1 (the end to the element rail 114A), and does not exceed a dimension L1 (corresponding to the length) of the inclined section 116b2 in the forward-backward direction X or a dimension L2 (corresponding to the length) of the connecting section 116p1 in the forward-backward direction X. This means that the front end of the inclined section 116b2 (the end to the element rail 114B) does not extend beyond the front end of the connecting section 116p1 in the forward-backward direction X, so that the inclined section 116b2, when viewed from the rear (as in Fig. (as shown in Figure 7) is concealed behind the half-tooth section 116b01 and does not project between the connecting section 116p1 and the head section 116p2 of the half-tooth section 116b1. Therefore, the inclined section 116b2 does not impede the engagement between the half-tooth section 116b1 and the element of the opposing element rail 114B.
[0028] Furthermore, in the embodiment as described in Fig. Figure 6 shows the leading edge of the inclined section 116b2 in the forward-backward direction X (the edge to the element rail 114A) having a chamfer 116r. Therefore, when the slides 120A and 120B slide on the locking bars 110A and 110B and cross the releasable pin 116 (the releasable pin 116 is inserted into the slides 120A and 120B), the locking pins 126 are not easily damaged even if the releasable pin 116 and the retaining pin 118 are engaged during the actuation process (the state that is in Fig.(as shown in Figure 2) are not yet fully engaged, and unintentional contact occurs between the locking pins 126 of the slides 120A and 120B and the leading edge of the inclined section 116b2 of the projection 116b of the releasable pin 116, as they come into contact with the leading edge of the inclined section 116b2, which has the chamfer 116r. That is, the chamfer 116r prevents the locking pins 126 from breaking due to contact with the leading edge of the inclined section 116b2. However, in other embodiments, which are not shown, the chamfer 116r can also be dispensed with, as long as the dimension D1 (which corresponds to the thickness / depth) of the inclined section 116b2 is larger than the extent T of the projection of the locking pins 126.Furthermore, when the slides 120A and 120B slide on the locking rails 110A and 110B and disengage from the release pin 116 (the release pin 116 is pulled out of the slides 120A and 120B), the release pin 116 and the retaining pin 118 are in an engaged state, and there is no risk that the locking pins 126 of the slides 120A and 120B will unintentionally come into contact with the trailing edge of the inclined section 116b2 of the projection 116b of the release pin 116. Therefore, no chamfer is provided on the trailing edge of the inclined section 116b2; however, in other embodiments not shown, a chamfer may also be provided on the trailing edge of the inclined section 116b2. The revelation is not limited to this and can be adapted as needed.
[0029] In summary, in the two-way separating element of the disclosure, the releasable pin has a releasable pin body, a releasable pin projection projecting from the releasable pin body, and a recess located at the rear end of the releasable pin projection. The retaining pin has a retaining pin body and a retaining pin projection projecting from the retaining pin body and engaging with the recess. The releasable pin projection has a half-tooth section and an inclined section located on a top surface (i.e.,The inclined section has a sloped surface that inclines from an upper surface of the body of the releasable pin to a projecting lateral edge of the releasable section and from a top to a bottom (corresponding to the front to the back), and a dimension (corresponding to a thickness / depth) of the inclined section in the upward-downward direction is greater than the extent of the projection of the locking pin that extends from the wing in the upward-downward direction into the element channel. Thus, the projection of the releasable pin can, through the inclined section having a large dimension (thickness), maintain a large contact area between the projection of the releasable pin and the retaining pin projection, and, through the inclined section having a large dimension (depth), avoid the locking pin of the slide.Preferably, the inclined surface of the inclined section has a curved surface, such as a first curved surface and a second curved surface, which are connected to each other and have different curvatures, thereby further improving the large contact area between the projection of the releasable pin and the retaining pin projection. Accordingly, the two-way separating element of the disclosure can compensate for the large contact area of the projection of the releasable pin and the retaining pin projection and prevent a collision with the locking pin of the slide.
