  The present invention includes an open fastener opening / closing insert that allows the left and right fastener stringers to be separated after the slide fastener is slid to the lowest position to open the slide fastener, and the opening / closing insert. It relates to a slide fastener.

  2. Description of the Related Art Conventionally, there has been known a separation / insertion tool for separating left and right fastener stringers after sliding a slide fastener slider to the lowest position. For example, the separation / insertion tool generally used in the past is provided with a box bar formed integrally with the box at the lower end of the right fastener stringer in front view, and attached to the lower end of the left fastener stringer. The 1st pin member currently made can be freely inserted or extracted with respect to the said box. In the conventional slide fastener provided with the opening and closing insert, when the left and right fastener stringers are separated from each other, it is necessary to perform an operation of pulling up the left fastener stringer upward while holding the right fastener stringer. is there. Further, when the left and right fastener stringers are joined together, the first pin member attached to the lower end of the left fastener stringer is inserted into the slider and the box while holding the right fastener stringer. There is a need.

In such a slide fastener, a split-fitting insert for improving the separation between the right and left fastener stringers when the slider is lowered and for improving the startability of the slider when closing the fastener is a German patent. This is disclosed in Japanese Patent Application No. 10124704 (Patent Document 1).
In the separation / insertion tool described in Patent Document 1, a seesaw attached to the center of a box is configured to swing around an axis provided in the box. When the slider is lowered to a position where it comes into contact with the box, the left end of the seesaw contacts the lower end of the hook that extends downward from the slider and enters the box, and tilts the seesaw counterclockwise. To do.

  At this time, the right end of the seesaw works to push up the lower end of the hook formed on the pin member at the lower end of the right side fastener stringer that can be detached from the box, and to push up the right side fastener stringer from the box. Can be easily separated.

  On the other hand, when the pin member at the lower end of the right fastener stringer is fitted into the box, the lower end of the hook formed on the pin member comes into contact with the right end of the seesaw, and acts to tilt the seesaw clockwise. At this time, the left end of the seesaw serves to push up the lower end of the hook extending downward from the slider, so that the startability of the slider when closing the fastener is improved.

Also, by lifting the slider from the box, the hook extending downward from the slider raises the left shoulder end of the T-shape formed on the top of the seesaw, so the seesaw tilts clockwise and the T-shape The right shoulder end of the right side pushes down the hook formed on the pin member of the right side fastener stringer. Thereby, the pin member of the right fastener stringer can be lowered to a predetermined position, and the pair of left and right service teeth formed on the fastener stringer can be easily engaged with each other.

  Similar to the first pin member 30, a hook-like lock claw 41 is formed on the lower side of the second pin member 40 on the engagement axis CL side. Further, when the second pin member 40 is inserted into the box 50 above the collar portion of the lock claw 41 of the second pin member 40, the neutral rotation cam 62 (in FIG. The neutral position rotation convex portion 44 is formed to engage the rotation member 60 and rotate the rotation member 60 to the neutral position. A back relief 45 that facilitates insertion and removal of the box 50 and the slider 20 is formed on the second pin member 40 on the opposite side of the engagement axis CL.

  Next, the structure of the detachment preventing mechanism portion for the pin member of the opening / closing insert 22 according to the present invention will be described with reference to a cross-sectional view. FIG. 5 is a cross-sectional view taken along the line KK, with the front side of the first pin member 30 and the second pin member 40 in a meshed state of the slide fastener 10 shown in FIGS. 1 and 2 (see FIG. 2). It shows a state where both the first pin member 30 and the second pin member 40 are inserted into the box 50.

  In FIG. 5, the lock claw insertion portion 64 formed on the rotating member 60 shares the insertion portion of the lock claw 31 of the first pin member 30 and the insertion portion of the lock claw 41 of the second pin member 40. This is an embodiment. In addition to this embodiment, another embodiment in which the insertion portion dedicated to the locking claw of the first pin member and the insertion portion dedicated to the locking claw of the second pin member are separately provided on the rotating member is shown in FIG. This will be described later with reference to FIG.

  The first pin member 30 and the second pin member 40 of the slide fastener 10 shown in FIG. 5 are a left wall 51, a right wall 52, and a front wall 53 (not shown in FIG. 5) that form four surfaces of the box 50. 12) and a space 57 that is surrounded by the rear wall 54 and opened at the top of the box 50 is inserted downward.

  Among these, the first pin member 30 is inserted into a left insertion groove formed between the left wall 51, the front wall 53, the rear wall 54, and the rotating member 60 of the box 50. The second pin member 40 is inserted into a right insertion groove formed between the right wall 52, the front wall 53, the rear wall 54, and the rotating member 60. Therefore, the box 50 is positioned in the left-right direction in FIG. 5 (LR direction shown in FIG. 5) and in the front and back direction of the paper surface in FIG.

  Further, the positioning of the box body 50 in the vertical direction (the UD direction shown in FIG. 5) prevents the lock claw 31 of the first pin member 30 and the lock claw 41 of the second pin member 40 from being pulled out. Positioning is performed by being sandwiched between the means 68 and the box inner bottom surface 55. The rotating member 60 is pivotally supported in both the clockwise and counterclockwise directions (the RT direction shown in FIG. 5) with respect to the box body 50. Both the lock claw 31 and the lock claw 41 of the first pin member 30 and the second pin member 40 are engaged with the end of the engagement / release surface 65 of the formed lock claw insertion portion 64 in a balanced manner. Therefore, even if both the first pin member 30 and the second pin member 40 are to be extracted from the box 50 in the state shown in FIG. 50 is configured not to be detached from the first pin member 30 and the second pin member 40.

  The central projecting portion 56 projecting in a mountain shape near the meshing axis CL of the inner bottom surface 55 of the box body is in a state where only one of the first pin member 30 and the second pin member 40 is inserted into the box body 50 ( For example, in the state shown in FIG. 3 or FIG. 4), the box body 50 is a protruding portion for preventing the box member 50 from being largely inclined with respect to the inserted pin member. A concave back relief 35 for facilitating insertion / removal with respect to the box 50 and the slider 20 is provided on the opposite side surface of the first and second pin members 30, 40 across the engagement axis CL. Is formed.

  In this kind of separation / insertion tool, when the pin member is inserted into the box body and the slider or when it is removed from the box body and the slider, the pin member is operated in parallel with the meshing axis CL. It is difficult to operate diagonally upward or diagonally downward. At this time, the box and the slider and the pin member interfere with each other, so that the operation does not go smoothly. According to this embodiment, since the concave back relief 35 is provided as described above, the first pin member 30 or the second pin member 40 can be easily tilted with respect to the box and the slider, and the first pin The insertion / extraction operation of the member 30 or the second pin member 40 can be performed easily and smoothly.

  Next, the process of lowering the slider 20 from the state shown in FIG. 5 to a position in contact with the box 50 and extracting the first pin member 30 from the box 50 will be described with reference to FIGS. FIG. 6 is a view showing a state where the first pin member 30 is lifted by L1 from the box 50 by pulling the left fastener stringer 16 upward. FIG. 7 is a view showing a state in which the left fastener stringer 16 is further lifted upward from the state shown in FIG. 6 and the first pin member 30 is lifted from the box 50 by L2.

  As shown in FIG. 6, when the operation of pulling up the first pin member 30 from the box 50 is performed, the lock claw 31 formed on the meshing axis CL side below the first pin member 30 is formed on the rotating member 60. The rotation member 60 is rotated clockwise by engaging with the engagement / release surface 65 of the lock claw insertion portion 64 that has been set.

  For example, in the state where the first pin member 30 is lifted by L1, the opening direction of the lock claw insertion portion 64 is rotated clockwise by an average angle θL1 (in the example shown in FIG. 6, about 45 °). On the other hand, since the lock claw 41 formed on the side of the engagement axis CL at the lower part of the second pin member 40 is detached from the lock claw insertion portion 64 and engaged with the pin removal preventing means 68 of the rotating member 60, The box body 50 is not detached from the second pin member 40.

  As shown in FIG. 7, when the first pin member 30 is further pulled up, the lock claw 31 of the first pin member 30 is disengaged from the engagement / release surface 65 of the lock claw insertion portion 64 formed in the rotating member 60. Leave. Thereby, the 1st pin member 30 can be completely extracted from the box 50 and the slider 20, and can be made into the state shown in FIG.

  For example, as shown in FIG. 7, when the first pin member 30 is pulled up by L2, the opening direction of the lock claw insertion portion 64 in the rotating member 60 is an average angle θL2 (in the example shown in FIG. 7, about 135 °). It will stop in the rotated state. Even in this state, the lock claw 41 of the second pin member 40 is engaged with the pin removal preventing means 68 of the rotating member 60, so that the second pin member 40 cannot be removed from the box 50. Therefore, the box 50 does not detach from the second pin member 40.

  Next, when the first pin member 30 is inserted into the slider 20 and the box 50 from the state in which the first pin member 30 is completely removed, the lock claw 31 at the lower part of the first pin member 30 is moved to the rotating member. 7 is engaged with the engagement / release surface 65 of the lock claw insertion portion 64 formed in 60, and the state shown in FIG. When the first pin member 30 is further lowered, the lock claw 31 pushes the engagement / release surface 65 to lower the first pin member 30 while rotating the rotation member 60 counterclockwise. it can. Further, when the operation of pushing the first pin member 30 into the box 50 is continued, the state transitions to the state shown in FIG. 6, and the position where the tip of the first pin member 30 contacts the inner bottom surface 55 of the box 50. The first pin member 30 can be inserted.

  In the state shown in FIG. 6, the opening direction of the lock claw insertion portion 64 in the rotation member 60 is stopped after being rotated by the average angle θL1, and in this state, the lock claw 41 of the second pin member 40 is stopped. Remains engaged with the pin removal preventing means 68 of the rotating member 60. Therefore, in this state, the second pin member 40 cannot be extracted from the box 50.

  Therefore, it is necessary to further rotate the rotating member 60 counterclockwise by the angle θL1 to return the rotating member 60 to the neutral position. The mechanism for returning the rotating member 60 to the neutral position will be described later with reference to FIG. Here, first, the overall shape of the rotating member 60 will be described with reference to FIGS. 8 and 9, and the external shapes of the first pin member 30 and the second pin member 40 will be described with reference to FIGS. 10 and 11.

It is sectional drawing which shows a shape. As shown in FIG. 8, the lock claw insertion portion 64 is formed symmetrically with respect to the neutral axis ZZ. By engaging the lock claw 31 and the lock claw 41 with the lock claw insertion portion 64, the linear movement performed by the first pin member 30 and the second pin member 40 is changed to the rotation movement of the rotation member 60. An engagement / release surface 65 is formed for conversion (see FIGS. 5-7 for movement).

  The CC arrow view shown in FIG. 8 shows the neutral rotation cam 62 engaged with the neutral position rotation convex portion 34 of the first pin member 30 or the neutral position rotation convex portion 44 of the second pin member 40. It is sectional drawing which shows a shape. As shown in FIG. 8, the neutral turning cam 62 is formed symmetrically with respect to the neutral axis ZZ. The function of the neutral rotation cam 62 will be described later with reference to FIGS. 16 and 17.

  The position of the cutting plane CC is the midpoint of the rotation axis RC of the rotation member 60 (the rotation axis passing through the centers of both shaft portions 66), and the pair of lock claw insertion portions 64 is The rotation member 60 is formed symmetrically with respect to the intermediate point of the rotation axis RC. Therefore, when the lock claw 31 or the lock claw 41 is inserted into the lock claw insertion portion 64 and the rotation member 60 is rotated, an equal force is applied to both the shaft portions 66. The rotation can be performed smoothly.

  Further, since the neutral rotation cam 62 is formed at an intermediate point of the rotation axis RC of the rotation member 60, the neutral rotation cam 62 is engaged with the neutral position rotation convex portion 34 or the neutral position rotation convex portion 44 to rotate. Even when the member 60 is rotated to the neutral position, an equal force is applied to both the shaft portions 66, so that the rotary member 60 can be smoothly rotated to the neutral position.

  FIG. 10 is a perspective view showing a detailed shape of the first pin member 30 attached to the lower end of the left fastener stringer 16, and FIG. 11 shows a detailed shape of the second pin member 40 attached to the lower end of the right fastener stringer 17. It is a perspective view shown.

  As shown in FIG. 10, two lock claws 31 having the same shape are formed in parallel below the first pin member 30. The two lock claws 31 are to be inserted into the two lock claw insertion portions 64 shown in FIG. The lock claw 31 and the lock claw insertion portion 64 having the same shape are formed at two locations so that an equal force is applied to the two shaft portions 66 at both ends of the rotation member 60 so that the rotation member 60 This is to make the rotation smooth.

  Further, in the final stage of inserting the first pin member 30 into the box 50 above the intermediate portion of the lock claw 31 formed at two places below the first pin member 30, the rotating member 60. By engaging with the neutral rotation cam 62 (see FIG. 8), a neutral position rotation convex portion 34 for rotating the rotation member 60 to the neutral position is formed.

  Similarly, as shown in FIG. 11, two lock claws 41 having the same shape are formed in parallel under the second pin member 40. The two lock claws 41 are to be inserted into the two lock claw insertion portions 64 shown in FIG. Further, above the middle portion of the lock claw 41 formed at two places below the second pin member 40, the rotating member is the last stage when the second pin member 40 is inserted into the box 50. By engaging with a neutral rotation cam 62 (see FIG. 8), a neutral position rotation convex portion 44 for rotating the rotation member 60 to the neutral position is formed.

  Next, the shape of the box 50 will be described with reference to FIG. FIG. 12 is a perspective view showing a state in which the assembled box 50 is disassembled.

  As shown in FIG. 12, the box 50 includes a front box 53, a left wall 51, a right wall 52, a box inner bottom 55, and a front box 50 </ b> F formed with a central protrusion 56, a rear wall 54, A left wall 51, a right wall 52, a box inner bottom surface 55, and a back box body 50R in which a central protrusion 56 is formed.

  A bearing 58 having a cylindrical pivoting surface for pivotally supporting the shaft portion 66 of the rotating member 60 is formed on the front wall 53 of the front box body 50F and the central portion of the back box body 50R. A flat shaft locking portion 59 for restricting the rotating operation of the rotating member 60 by engaging with the bearing locking portion 67 shown in FIG. Is formed. Since the shaft locking portion 59 is formed outside the outer diameter of the shaft portion 66 of the rotating member 60, the shaft portion 66 of the rotating member 60 can be inserted into the bearing 58. 58 can rotatably support the shaft portion 66.

  A dwell 71 projects from the joint surface 70 of the front box body 50F and the back box body 50R. By positioning the dowel 71 in the dowel hole 72 formed in the joint surface 70, the positioning and joining of the front box body 50F and the back box body 50R can be maintained. When the front box body 50F and the back box body 50R are formed of resin, adhesion or ultrasonic welding can be used to join the front box body 50F and the back box body 50R. Further, when the front box body 50F and the back box body 50R are formed of metal, the front box body 50F and the back box body 50R can be bonded or bonded together by brazing.

FIG. 13 shows another embodiment of the box.
A box 150 shown in FIG. 13 is an integrally formed box, unlike the two parts of the front box 50F and the back box 50R shown in FIG. In the box 50 shown in FIG. 12, the shaft 58 of the rotating member 60 is inserted into the bearing 58, and then the front box 50F and the back box 50R are joined together so that the bearing 58 pivots the shaft 66. Although the front wall 53 (not shown) and the rear wall 54 are integrally formed as in the box 150 shown in FIG. 13, the shaft portion 66 of the rotating member 60 can be supported. A device for insertion into the bearing 58 is required.

  In the embodiment shown in FIG. 13, the front wall 53 (see FIG. 14) and the rear wall 54 have portions of the front wall 53 and the rear wall 54 in order to facilitate the insertion of the shaft portion 66 in the portion above the bearing 58. A bearing introduction portion 157 having a reduced thickness is formed. Furthermore, an inclining inclined surface 159 is formed in order to expand the front wall 53 and the rear wall 54 outward and insert the shaft portion 66 into the bearing 58 by pressing the shaft portion 66 downward along the bearing introduction portion 157. Has been.

  When the shaft portion 66 has passed over the introduction inclined surface 159 and has been inserted into the concave portion in which the bearing 58 is formed, the front wall 53 and the rear wall 54 return to their original positions from the expanded state, and FIG. As shown, the shaft 66 is maintained inserted in the recess in which the bearing 58 is formed.

FIG. 14 is a cross-sectional perspective view of the box body 150 showing a state in which the shaft portions 66 formed at both ends of the rotating member 60 are inserted into the bearings 58 formed at two locations of the box body 150.
As shown in FIG. 14, a bearing introduction portion 157 is formed above the bearing 58 of the front wall 53 and the rear wall 54, and an introduction inclined surface 159 is formed below the bearing introduction portion 157. As shown in FIG. 14, once the shaft portion 66 is inserted into the recess in which the bearing 58 is formed, the front wall 53 and the rear wall 54 return to their original positions from the expanded state, and the bearing 58 is formed. The state where the shaft portion 66 is inserted into the recessed portion is maintained. Therefore, the rotating member 60 is pivotally supported with respect to the box 150.

  Next, the function of each part of the rotating member 60 shown in FIG. 8, each part of the first pin member 30 shown in FIG. 10, and each part of the second pin member 40 shown in FIG. This will be outlined with reference to FIG.

  FIG. 15 illustrates a place where the bearing mechanism and the rotation prevention mechanism portion of the rotation member 60, the separation prevention mechanism portion of the box 50 and the pin member, and the neutral rotation mechanism portion of the rotation member 60 are formed. It is explanatory drawing of the separation fitting 22.

  FIG. 15 shows a state in which the box 50 is cut into a bearing mechanism and rotation prevention mechanism portions 50A and 50E, a pin member detachment prevention mechanism portion 50B and 50D, and a neutral rotation mechanism portion 50C. About the 1st pin member 30, the state which cut | disconnected and divided | segmented into the separation prevention mechanism part 30B, 30D of pin members and the neutral rotation mechanism part 30C is shown. The operation of the pin member detachment preventing mechanism portions 30B and 30D is as shown in FIGS.

  In addition, the effect | action of the neutral rotation mechanism part 50C is demonstrated using subsequent FIG. 16 and FIG. Further, the bearing and rotation prevention mechanism portions 50A and 50E will be described with reference to FIGS.

First, the mechanism of the neutral turning mechanism 50C for returning the turning member 60 to the neutral position when the pin member 30 is inserted from the state shown in FIG. 6 will be described with reference to FIG.
FIG. 16 is an LL arrow view of the slide fastener 10 shown in FIG. As shown in FIG. 6, when the first pin member 30 is inserted into the box body 50, if the dimension between the lower end of the first pin member 30 and the box inner bottom surface 55 becomes L1 or less, the lock The claw 31 is separated from the lock claw insertion portion 64. Therefore, the angle in the average opening direction of the lock claw insertion portion 64 in the rotating member 60 cannot be made equal to or less than the angle θL1 (about 45 ° in the example shown in FIG. 16) from the neutral position.

  Therefore, as shown in FIG. 16, when the neutral rotation cam 62 is formed on the rotation member 60 and the first pin member 30 is further lowered, the lock claw 31 is separated from the lock claw insertion portion 64. A neutral position rotation convex portion 34 for contacting the rotation cam 62 and rotating the rotation member 60 to the neutral position is formed downward on the meshing axis line CL side of the first pin member 30.

  Accordingly, when the first pin member 30 is further lowered from the state shown in FIG. 16, the neutral position rotation convex portion 34 comes into contact with the neutral rotation cam 62 and rotates the rotation member 60 counterclockwise. Can be moved. A state after the first pin member 30 is further lowered will be described with reference to FIG.

  FIG. 17 is a view showing a state in which the first pin member 30 and the second pin member 40 of the slide fastener 10 are inserted all the way into the box body 50, and is a view taken along line LL in FIG. When the first pin member 30 is completely inserted into the box body 50 from the state shown in FIG. 16, the neutral position turning convex portion 34 and the neutral position turning convex portion 44 are changed to the neutral turning cam 62 as shown in FIG. 17. Therefore, the rotation member 60 is positioned at a position (neutral position) symmetrical with respect to the meshing axis CL.

  As shown in FIG. 17, when the rotation member 60 is in the neutral position, the lock claw 31 of the first pin member 30 and the second pin member are placed on the engagement / release surface 65 of the lock claw insertion portion 64. Since both of the 40 lock claws 41 are engaged with each other in a balanced manner, the box body 50 does not separate from the first pin member 30 and the second pin member 40.

  16 and 17, the first pin member 30 is inserted and the rotation member 60 is rotated to the neutral position. However, the lock claw 31, the lock claw 41, and the neutral position rotation convex portion 34 are described. And the neutral position turning convex portion 44 has a line-symmetric shape with respect to the meshing axis CL, and the turning member 60 has a shape symmetrical with respect to the meshing axis CL, so that the second pin member 40 is inserted. Even in this case, the rotating member 60 can be rotated to the neutral position.

  5 to 7, the lock claw 31 and the neutral position turning convex portion 34 of the first pin member 30 are the second pin member as described in the description of inserting and removing the first pin member 30. Forty lock claws 41 and neutral position turning convex portions 44 and the meshing axis CL are line symmetrical. Further, in the state shown in FIG. 5, since the rotating member 60 is also symmetrical with respect to the meshing axis CL, the second pin member 40 can be similarly inserted into and removed from the box 50.

Next, the bearing mechanism and the rotation prevention mechanisms 50A and 50E will be described with reference to FIGS.
FIG. 18 is a diagram illustrating a state where the first pin member 30 and the second pin member 40 of the slide fastener 10 are inserted to the back of the box body 50 and the rotating member 60 is in a neutral state. FIG. 18 is a view taken along the arrow MM in FIG. FIG. 19 is a diagram illustrating a state in which the first pin member 30 of the slide fastener 10 is extracted from the box body 50 and only the second pin member 40 is inserted into the box body 50. FIG. 19 is also a view taken along the line MM in FIG.

  In the state shown in FIG. 18, both the lock claw 31 of the first pin member 30 and the lock claw 41 of the second pin member 40 are engaged / released surfaces of the lock claw insertion portion 64 formed on the rotating member 60. Since both the first pin member 30 and the second pin member 40 are engaged with 65, the first pin member 30 and the second pin member 40 cannot be removed simultaneously. However, by pulling up one of the first pin member 30 and the second pin member 40, the lock claw 31 or the lock claw 41 is inserted into the lock claw insertion portion 64 and the rotation member 60 is rotated. Any one of the first pin member 30 and the second pin member 40 can be extracted.

  As shown in FIGS. 5 to 7, when the first pin member 30 is extracted, the rotation member 60 rotates clockwise. Moreover, when extracting the 2nd pin member 40, the rotation member 60 rotates counterclockwise. While the rotation member 60 is rotated from the neutral state by the angle θL3 (see FIG. 19), the cylindrical shaft portion 66 of the rotation member 60 is in contact with the shaft locking portion 59. Can freely rotate inside the bearing 58, and the first pin member 30 or the second pin member 40 can be extracted. The relationship between the bearing 58 and the shaft portion 66 when either the first pin member 30 or the second pin member 40 is extracted will be described with reference to FIG. 19 below.

  In the state shown in FIG. 19, the first pin member 30 is completely extracted, and the box 50 is in a state of hanging from the second pin member 40. In this state, there is a high possibility that a force is applied in a direction in which the second pin member 40 and the box body 50 are pulled apart.

  As in the embodiment shown in FIG. 19, when either one of the first pin member 30 or the second pin member 40 is extracted, the rotating member 60 rotates by an angle θL3 or more, or returns to an angle θL3 or less. As a result, it becomes impossible to insert the lock claw 31 of the first pin member 30 into the lock claw insertion portion 64 or to prevent the second pin member 40 from being removed from the box 50 in advance. Therefore, the rotation of the rotating member 60 is restricted by engaging the shaft locking portion 59 and the bearing locking portion 67 formed in a part of the bearing 58.

  Thereby, even when a force is applied in a direction in which the second pin member 40 and the box 50 are separated from each other, the lock claw 41 of the second pin member 40 is engaged with the pin removal preventing means 68 of the rotating member 60. Can continue to. Then, the box body 50 is prevented from being detached from the second pin member 40. Further, the lock claw insertion portion 64 of the rotating member 60 can be held at a position where the lock claw 31 can be easily inserted.

  In the embodiment shown in FIGS. 18 and 19, the bearing locking portion 67 has a phase angle of 45 ° with respect to the average opening direction of the lock claw insertion portion 64 (shown in FIG. 19, angle θL3). Although it is formed at a position, it can be formed at a position having a phase angle of 30 ° to 60 °.

  When the first pin member 30 is inserted into the slider 20 and the box 50 from the state shown in FIG. 19, the lock claw 31 of the first pin member 30 is fitted into the lock claw insertion portion 64, and the lock claw insertion portion 64 is While pushing down, a force to rotate counterclockwise works. When the rotation member 60 is rotated counterclockwise while being pushed downward, the bearing locking portion 67 formed on the shaft portion 66 is separated from the shaft locking portion 59 and the shaft portion 66 contacts the lower side of the bearing 58. Thus, the rotating member 60 is pivotally supported so as to be rotated toward the neutral position. Then, the first pin member 30 can be inserted into the box 50.

  In the state shown in FIG. 19, the state where the second pin member 40 is inserted has been described. However, the shape of the tip portion of the first pin member 30 and the second pin member 40, the shape of the box 50, and Since the shape of the rotating member 60 is symmetrical with respect to the meshing axis CL, even in a state where only the first pin member 30 is inserted into the box body 50, as in the case described above, the shaft engagement is performed. The rotation of the rotation member 60 can be limited by the engagement between the stop portion 59 and the bearing locking portion 67.

  Next, another embodiment of the separation / insertion tool according to the present invention will be described with reference to FIGS. 20 to 22, the rotation member 260 includes a lock claw insertion portion 264L dedicated to the lock claw 231 in the first pin member 230 and a lock claw insertion portion 264R dedicated to the lock claw 241 in the second pin member 240. It is a figure explaining the Example provided independently separately. FIG. 20 is a cross-sectional view of the slide fastener 210 with the front side of the first pin member 230 and the second pin member 240 as a cross section, similar to FIG. 5 described above. It is a figure which shows the state which inserted both the 2 pin members 240 and has stopped the rotation member 260 in the neutral position.

  The first pin member 230 and the second pin member 240 of the slide fastener 210 shown in FIG. 20 are a left wall 251, a right wall 252, and a front wall (not shown in FIG. 20) that form four surfaces of the box 250. And a space 257 that is surrounded by the rear wall 254 and opens at the top of the box 250.

  The first pin member 230 is fitted into a left insertion groove formed between the left wall 251, the front wall, the rear wall 254, and the rotating member 260 of the box body 250. Further, since the second pin member 240 is inserted into the right insertion groove formed between the right wall 252, the front wall, the rear wall 254, and the rotating member 260, the box body 250 is illustrated in FIG. 20 in the left-right direction (LR direction shown in FIG. 20) and in the front and back direction of the paper surface of FIG.

  Further, the positioning of the box body 250 in the vertical direction (the UD direction shown in FIG. 20) is performed by using the lock claw 231 of the first pin member 230 and the lock claw 241 of the second pin member 240 with the rotating member 260 and the box body. Positioning is performed by being sandwiched between the inner bottom surface 255. The box body 250 is not fixed to any of the first pin member 230, the second pin member 240, the left fastener stringer 216, and the right fastener stringer 217, but is detached from the first pin member 230 or the second pin member 240. There is no.

  The rotating member 260 is pivotally supported by the box body 250 so as to be rotatable in both clockwise and counterclockwise directions (RT direction shown in FIG. 20). The lock claw 231 of the first pin member 230 engages with the engagement / release surface 265L of the lock claw insertion portion 264L formed in a part of the rotating member 260, and the engagement / release of the lock claw insertion portion 264R. The lock claw 241 of the second pin member 240 is engaged with the release surface 265R. Therefore, in the state shown in FIG. 20, even if both the first pin member 230 and the second pin member 240 are to be extracted from the box body 250, the rotation member 60 cannot rotate, and The first pin member 230 and the second pin member 240 are configured not to be separated.

Next, a process of extracting the first pin member 230 from the box body 250 will be described with reference to FIGS. 21 and 22.
FIG. 21 is a diagram illustrating a state in which the rotating member 260 is rotated 45 ° clockwise from the neutral position by pulling up the first pin member 230 from the state illustrated in FIG. 20. FIG. 22 is a view showing a state in which the first pin member 230 is further lifted upward from the state shown in FIG. 21 and the turning member 260 is turned 90 ° clockwise from the neutral position.

  As shown in FIG. 21, when the operation of pulling up the first pin member 230 from the box body 250 is performed, the lock claw 231 formed on the meshing axis CL side below the first pin member 230 is formed on the rotating member 260. The rotation member 260 is rotated clockwise by being inserted into the lock claw insertion portion 264L. The first pin member 230 can be pulled upward by the rotation member 260 performing a rotation operation.

  On the other hand, in the state shown in FIG. 21, the lock claw 241 formed on the side of the engagement axis CL at the lower part of the second pin member 240 is disengaged from the lock claw insertion portion 264R and is engaged with the pin removal preventing means 268 of the rotating member 260. Therefore, the second pin member 240 cannot be removed from the box 250.

  As shown in FIG. 22, when the first pin member 230 is further pulled up, the lock claw 231 of the first pin member 230 is disengaged from the lock claw insertion portion 264 </ b> L formed on the rotating member 260. 230 can be completely removed from the box 250 and the slider 20. Even in this state, the lock claw 241 of the second pin member 240 is engaged with the pin removal preventing means 268 of the rotating member 260, so that the second pin member 240 cannot be removed from the box body 250. It is. Therefore, the box body 250 is not detached from the second pin member 240.

  Next, when the first pin member 230 is inserted into the slider 20 and the box body 250 after the first pin member 230 is completely removed, as shown in FIG. The claw 231 can be fitted into the lock claw fitting portion 264L formed on the turning member 260, and the first pin member 230 can be lowered while turning the turning member 260 counterclockwise.

  Further, when the first pin member 230 is pushed into the box body 250, the rotating member 260 further rotates counterclockwise, and the state transitions to the state shown in FIGS. The tip portion can be inserted to a position where it abuts against the box body inner bottom surface 255 of the box body 250. In the state shown in FIG. 20, since the rotating member 260 has already returned to the neutral position, the neutral rotating cam 62 and the neutral position rotating convex portion 34 as shown in FIGS. 16 and 17 are unnecessary. Become.

Next, another embodiment of the bearing locking portion formed on the rotating member and the shaft locking portion formed on the box is shown in FIGS.
FIG. 23 shows the implementation of the release fitting 322 provided with a biasing means 380 that biases the bearing locking portion 367N formed on the rotating member 360 toward the shaft locking portion 359 formed on the box 350. It is a perspective view which shows an example. For convenience of explanation, the box 350 of the opening / closing insert 322 shown in FIG. Moreover, the description of the fastener tape of the left fastener stringer and the right fastener stringer is omitted, and only the first pin member 30 and the second pin member 40 are described.

  24 is a perspective view showing a state in which the central portion of the box 350 in the opening / closing insert 322 shown in FIG. 23 is cut in a cross section perpendicular to the rotation axis of the rotation member 360. It is a figure which shows the state which inserted the rotation member 360 in the bearing 358 (refer FIG. 25) of the body 350. FIG.

  FIG. 25 is a view showing the bearing 358, the shaft locking portion 359, and the biasing means storage portion 382 in an easy-to-see manner by removing the rotating member 360 from the box 350 shown in FIG. 26 is a view showing a state in which the box 350 shown in FIG. 24 is further cut in parallel with the rotation axis of the rotation member 360 and the urging means 380 is fitted in the urging means storage portion 382. is there.

  The state shown in FIG. 23 is a state in which both the first pin member 30 and the second pin member 40 are inserted into the space of the box 350, and the rotating member 360 is in the neutral position. . In the embodiment shown in FIG. 23, when the rotating member 360 is in the neutral position, the shaft locking portion 367N is provided with the bearing locking portion 367N that prevents the rotating operation of the rotating member 360 in order to maintain the neutral position. (See FIG. 27 below).

  Similarly to the state shown in FIG. 19, the first pin member 30 or the second pin member 40 is extracted from the box 350 and only one of the pin members is inserted into the box 350. In order to prevent the rotating operation of the rotating member 360, a bearing locking portion 367 is formed on a part of the pivotal support surface of the shaft portion 366 (the operation will be described with reference to FIG. 28).

  As shown in FIGS. 23 to 26, the shaft portion 366 of the rotating member 360 is pivotally supported by a bearing 358 formed on the front wall and the rear wall of the box 350. The plate-like urging means 380 that urges the rotating member 360 upward is stored in the urging means storage 382 of the box 350. The biasing means storage portion 382 is a V-shaped groove convex in the opposite direction to the bearing 358, and when the biasing means 380 biases the rotating member 360 upward, the biasing means 380 Is formed so that it can be bent. As the material of the biasing means 380, a spring steel material, a copper alloy, or other materials can be used.

Next, a state in which the rotating member 360 is held at the neutral position will be described with reference to FIG.
FIG. 27 is a cross-sectional view of the rotation member 360 and the biasing means 380 in the bearing 358 portion of the box 350, and is a cross-sectional view of a plane orthogonal to the rotation axis of the rotation member 360.
As shown in FIG. 27, the urging means 380 stored in the urging means storage portion 382 urges the shaft portion 366 of the rotating member 360 present at the neutral position toward the axis. . Then, the planar bearing locking portion 367N formed on a part of the pivoting surface of the shaft portion 366 is replaced with the planar shaft locking portion 359 formed on a part of the pivoting surface of the bearing 358. Since the pressing is performed, the bearing locking portion 367N and the shaft locking portion 359 are engaged with each other. Then, the rotation of the rotation member 360 existing at the neutral position is restricted and held at the neutral position with a predetermined force.

  When the user performs an operation of extracting either the first pin member 30 or the second pin member 40, the planar bearing locking portion 367N is separated from the same planar shaft locking portion 359, and the shaft The part 366 slides relative to the shaft locking part 359. At this time, since the rotating member 360 moves slightly downward as shown in the figure, the shaft portion 366 pushes the biasing means 380 downward, and the central portion of the biasing means 380 is bent downward. Become.

  Next, a state in which one of the first pin member 30 and the second pin member 40 is extracted from the box 350 will be described with reference to FIG. 28 is a view of the box 350 cut along the same cross section as FIG.

  As shown in FIG. 28, when the first pin member 30 is extracted from the box 350, the rotating member 360 is rotated by an angle θL3 from the neutral state. Even in this state, the urging means 380 urges the shaft portion 366 of the rotating member 360 toward the axis. Then, the planar bearing locking portion 367 formed on a part of the pivoting surface of the shaft portion 366 is replaced with the planar shaft locking portion 359 formed on a part of the pivoting surface of the bearing 358. Since the pressing is performed, the bearing locking portion 367 and the shaft locking portion 359 are engaged. Therefore, the rotation of the rotation member 360 is restricted and held at that position.

  As described above, in the state where either the first pin member 30 or the second pin member 40 is removed, the rotation member 360 rotates more than the angle θL3 or returns to the angle θL3 or less. It is possible to prevent problems that the lock claw 31 of the 1-pin member 30 cannot be inserted into the lock claw insertion portion 64 or that the second pin member 40 is detached from the box 350. Moreover, the lock claw insertion part 64 (refer FIG. 24) currently formed in the rotation member 360 can be hold | maintained in the position where the lock claw 31 is easy to insert.

  In the state shown in FIG. 28, when the user performs an operation of inserting the removed first pin member 30 again, the planar bearing locking portion 367 is also separated from the planar shaft locking portion 359. Thus, the shaft portion 366 performs a sliding motion relative to the shaft locking portion 359. At this time as well, the rotating member 360 is lowered as shown in the figure, but when the shaft portion 366 pushes the urging means 380 downward, the central portion of the urging means 380 is bent downward.

  Thus, when the rotation member 360 exists in the neutral position, or when one of the first pin member 30 and the second pin member 40 is removed, the rotation operation of the rotation member 360 is hindered. Can do.

Next, FIG. 29 shows another embodiment of the break-fitting insert tool provided with a bearing locking portion formed on the rotating member and a shaft locking portion formed on the box.
In the embodiment shown in FIG. 23 to FIG. 28, as the biasing means 380 that biases the bearing locking portion 367 </ b> N formed on the rotating member 360 toward the shaft locking portion 359 formed on the box body 350, The embodiment using the biasing means 380 which is a separate part from the body 350 is shown. FIG. 29 shows an embodiment of a separation / insertion tool 422 in which a biasing means 480 is integrally formed in a part of the box body 450. FIG. 29 is a cross-sectional view of the rotating member 360 and the urging means 480 in the bearing 458 portion of the box 450 as in FIG. 27 described above. In addition, the rotation member 360 has shown the state which exists in a neutral position similarly to FIG.

  As shown in FIG. 29, the bearing 458 of the box body 450 pivotally supports the shaft portion 366 of the rotating member 360. The urging means 480 urges the bearing locking portion 367N formed on the rotating member 360 toward the shaft locking portion 459 formed on the box body 450.

  Further, as shown in FIG. 29, in order to obtain a predetermined spring constant, both ends of the wide biasing means 480 are integrally connected to the box body 450, and the biasing means is arranged above and below the biasing means 480. An air gap 482 for bending 480 is formed.

  Due to the action of the biasing means 480, a planar bearing locking portion 367N formed on a part of the pivoting surface of the shaft portion 366 is formed into a planar shape formed on a part of the pivoting surface of the bearing 458. Since the shaft locking portion 459 is pressed, the bearing locking portion 367N and the shaft locking portion 459 are engaged. Then, the rotation of the rotation member 360 existing at the neutral position is restricted and held at the neutral position with a predetermined force.

  When the user performs an operation of extracting either the first pin member 30 or the second pin member 40, the planar bearing locking portion 367N is separated from the same planar shaft locking portion 459, and the shaft The part 366 slides relative to the shaft locking part 459. At this time, since the rotating member 360 moves slightly downward as shown in the figure, the shaft portion 366 pushes the biasing means 480 downward, and the central portion of the biasing means 480 is bent downward. Become.

  In a state where either the first pin member 30 or the second pin member 40 is removed from the box 450, the rotating member 360 rotates about 135 ° from the neutral state (angle θL3 shown in FIG. 28). . Even in this state, the urging means 480 urges the shaft portion 366 of the rotating member 360 toward the axis. Then, the planar bearing locking portion 367 formed on a part of the pivot surface of the shaft portion 366 is replaced with the planar shaft locking portion 459 formed on a part of the pivot surface of the bearing 458. Since the pressing is performed, the bearing locking portion 367 and the shaft locking portion 459 are engaged. Therefore, the rotation of the rotation member 360 is limited and held with a predetermined force.

  Thus, in the state where either one of the first pin member 30 or the second pin member 40 is extracted, the rotation member 360 rotates by 135 ° or more, or returns to 135 ° or less, so that the first It is possible to prevent a problem that the lock claw 31 of the pin member 30 cannot be inserted into the lock claw insertion portion 64 or the second pin member 40 is detached from the box 450 in advance. Moreover, the lock claw insertion part 64 (refer FIG. 24) currently formed in the rotation member 360 can be hold | maintained in the position where the lock claw 31 is easy to insert.

  When the user performs an operation of reinserting the first pin member 30 from the state in which the first pin member 30 is removed, the planar bearing locking portion 367 is separated from the planar shaft locking portion 459. Thus, the shaft portion 366 performs a sliding motion relative to the shaft locking portion 459. At this time as well, the rotating member 360 is lowered, but when the shaft portion 366 pushes the urging means 480 downward, the central portion of the urging means 480 is bent downward.

  Thus, when the rotation member 360 exists in the neutral position, or when one of the first pin member 30 and the second pin member 40 is removed, the rotation operation of the rotation member 360 is hindered. Can do.

Next, FIGS. 30 and 31 show another embodiment of the bearing locking portion formed on the rotating member and the shaft locking portion formed on the box.
The embodiment shown in FIGS. 30 and 31 includes a shaft portion 566 that pivotally supports the rotating member 560 and bearing locking portions 567 and 567N that function to prevent the rotating operation of the rotating member 560, respectively. It is an Example of the separation fitting insert 522 formed in another position.
FIG. 30 is a perspective view of the rotating member 560 alone, and is a diagram illustrating an embodiment in which the shaft portion 566 and the bearing locking portions 567 and 567N are formed at different positions.

  As shown in FIG. 30, on the outside of the shaft portion 566 that pivotally supports the rotation member 560, a hexagonal bearing locking portion 567 that functions to prevent the rotation operation of the rotation member 560, 567N is formed. The bearing locking portions 567N formed at two opposite positions are locking portions for preventing the rotating operation when the rotating member 560 is in the neutral position. Further, the bearing locking portions 567 formed at the four opposite positions prevent the rotating operation of the rotating member 560 when either the first pin member 30 or the second pin member 40 is extracted. It is a locking part for making it work. Note that the lock claw insertion portion, the neutral rotation cam, and the pin removal preventing means are the same as those of the rotation member 60 described in FIG.

  FIG. 31 is a sectional view of the bearing locking portions 567 and 567N in a state where the shaft portion 566 of the rotating member 560 is inserted into the bearing of the box 550 and the rotating member 560 is pivotally supported. is there. In addition, the rotation member 560 has shown the state which exists in a neutral position.

  As shown in FIG. 31, a space 582 is formed in a portion of the box 550 that accommodates the bearing locking portions 567 and 567N, and a movable shaft that engages with the bearing locking portions 567 and 567N. A locking portion 559 is provided. The shaft locking portion 559 is urged toward the shaft core of the shaft portion 566 by the action of the urging means 580. An elastic body such as a spring can be used for the biasing means 580.

  Since the planar shaft locking portion 559 presses the planar bearing locking portion 567N by the action of the biasing means 580, a state where the shaft locking portion 559 and the bearing locking portion 567N are engaged is created. Can do. If it does so, rotation of the rotation member 560 which exists in a neutral position will be restrict | limited, and it will hold | maintain in a neutral position.

  When the user performs an operation of extracting either the first pin member 30 or the second pin member 40, the planar bearing locking portion 567N and the planar shaft locking portion 559 are separated from each other, The rotating member 560 performs a rotating motion. At this time, the biasing means 580 is contracted by elastic deformation, and both the shaft locking portions 559 move away from the bearing locking portions 567N.

  The embodiment shown in FIG. 31 is an explanatory view when the rotating member 560 is in the neutral position. Similarly, either the first pin member 30 or the second pin member 40 is extracted from the box 550. Even in this state, the rotation of the rotation member 560 is limited and held with a predetermined force. And the lock claw insertion part (refer FIG. 24) currently formed in the rotation member 560 can be hold | maintained in the position where the lock claw 31 is easy to insert.

FIG. 32 shows another embodiment of the bearing locking portion formed on the rotating member and the shaft locking portion formed on the box.
The embodiment shown in FIG. 32 is an embodiment of a separation / insertion tool 622 in which a biasing means 680 and a shaft locking portion 659 are integrally formed on a part of the box 650, and is similar to FIG. 27 described above. FIG. 6 is a cross-sectional view of the rotating member 660, the biasing means 680, and the shaft locking portion 659 in the bearing 658 portion of the box 650. In addition, the rotation member 660 has shown the state which exists in the neutral position or the position which extracted either the 1st pin member 30 or the 2nd pin member 40. FIG.

  As shown in FIG. 32, the bearing 658 of the box 650 pivotally supports the shaft portion 666 of the rotating member 660. The biasing means 680 biases the integrally formed shaft locking portion 659 toward the bearing locking portion 667 formed on the rotating member 660. In order for the biasing means 680 to obtain a predetermined spring constant, both ends of the wide biasing means 680 are integrally connected to the box body 650, and the biasing means 680 is bent above and below the biasing means 680. An air gap 682 is formed.

  In the embodiment shown in FIG. 32, the shaft locking portion 659 is formed in a convex spherical shape, and the bearing locking portion 667 is formed in a spherical concave shape. Therefore, since the shaft locking portion 659 and the bearing locking portion 667 are engaged by the bias of the biasing means 680, either the neutral position or the first pin member 30 or the second pin member 40 is extracted. Sometimes, the rotation of the rotation member 660 can be restricted and held with a predetermined force.

  When the user performs an operation of inserting or removing either the first pin member 30 or the second pin member 40, the spherical concave bearing locking portion 667 performs an operation of pushing up the shaft locking portion 659, and the bearing locking The engagement between the portion 667 and the shaft locking portion 659 is released. Then, the shaft locking portion 659 performs a relatively sliding motion while being biased in the direction of the shaft portion 666.

  Further, similarly to the state in which the rotation member 660 exists at the neutral position, the rotation of the rotation member 660 can be performed even when the rotation member 660 has extracted either the first pin member 30 or the second pin member 40. The movement can be limited and held with a predetermined force.

Next, FIGS. 33 and 34 show another embodiment of the bearing locking portion formed on the rotating member and the shaft locking portion formed on the box.
The embodiment shown in FIG. 33 is an embodiment of a break-off fitting 722 in which a shaft locking portion 759 is arranged on the back wall surface of the bearing 758 formed on the front wall 753 and the rear wall 754 of the box 750. FIG. 6 is a cross-sectional view of a box body 750 cut along a rotational axis portion of a moving member 760. In addition, in the Example shown in FIG. 33, the rotation member 760 has shown the state which exists in a neutral position.

  As shown in FIG. 33, the bearing 758 of the box body 750 pivotally supports the shaft portion 766 of the rotating member 760. A bearing locking portion 767N for engaging with a shaft locking portion 759 biased in a direction protruding from the inner wall surface of the bearing 758 is provided on the end surface of the shaft portion 766 of the rotating member 760. The shaft locking portion 759 is biased in the direction of the rotating member 760 by biasing means 780 such as a spring built in the front wall 753 and the rear wall 754.

  As the bearing locking portion 767N, a hemispherical concave portion, a mortar-shaped concave portion, a tapered concave portion, or other concave portions can be used. Moreover, it is possible to use a component such as a plunger instead of the counterpart shaft locking portion 759 and the biasing means 780.

  The shaft locking portion 759 and the bearing locking portion 767N are disposed at a position away from the rotation axis of the rotation member 760 by a predetermined radius, and the shaft locking portion 759 engages with the bearing locking portion 767N. As a result, the rotation of the rotation member 760 can be restricted and held at a predetermined position.

  When the user performs an operation of inserting or removing either the first pin member 30 or the second pin member 40, the rotation member 760 starts the rotation operation from the neutral position. Then, the bearing locking portion 767N performs an operation of pushing the shaft locking portion 759 inward of the front wall 753 and the rear wall 754, so that the engagement between the bearing locking portion 767N and the shaft locking portion 759 is released. Then, since the shaft locking portion 759 and the rotation member 760 slide relatively while the shaft locking portion 759 is urged toward the end surface of the rotation member 760, the shaft locking portion 759 is rotatable.

Next, the position where the bearing locking portion 767N is established and an example of the quantity thereof will be described with reference to FIG.
As shown in FIG. 34, on the end surface of the shaft portion 766 formed on both sides of the rotation member 760, a bearing locking portion 767N for limiting the rotation of the rotation member 760 in the neutral position, and the first In the state where either one of the pin member 30 or the second pin member 40 is extracted, two bearing locking portions 767 that restrict the rotation of the rotation member 760 are provided.

  In the embodiment shown in FIG. 33, when the rotation member 760 is in the neutral position, the shaft locking portion 759 is engaged with the bearing locking portion 767N by the urging force of the urging means 780, and the rotation member 760 is engaged. Although the state that restricts the pivoting operation of the first pin member 30 or the second pin member 40 is present in the position where the pivot member 760 is removed, the shaft locking portion 759 is also provided. By engaging with the bearing locking portion 767, the rotation of the rotation member 760 can be limited.

FIG. 35 shows another embodiment of the bearing locking portion formed on the rotating member and the shaft locking portion formed on the box.
In the embodiment shown in FIGS. 33 and 34, a shaft locking portion 759 is disposed on the back wall surface of the bearing 758 formed on the front wall 753 and the rear wall 754 of the box body 750, and this shaft locking portion 759 is used as a dedicated one. The biasing means 780 is used to bias toward the end surface of the rotating member 760. On the other hand, in the embodiment of the opening / closing fitting 822 shown in FIG. 35, instead of the independent biasing means 780, the front wall 853 (biasing means) and the rear wall 854 (biasing means) of the box 850 are used. The shaft locking portion 859 is urged toward the end surface of the rotating member 760 by using the elastic force. Note that the rotating member 760 shown in FIG. 35 can adopt the same shape as the rotating member 760 shown in FIG.

  As shown in FIG. 35, the shaft locking portion 859 is rotated by using an elastic force when the shaft locking portion 859 is biased inward in the direction in which both the front wall 853 and the rear wall 854 are closed. The member 760 is biased toward the bearing locking portions 767 and 767N. Thereby, the shaft locking portion 859 and the bearing locking portions 767 and 767N can be engaged.

  Thus, as in the case shown in FIG. 33, in the state where the rotation member 760 exists in the neutral position or the state where either the first pin member 30 or the second pin member 40 is removed, the rotation member The unnecessary rotation of 760 can be restricted and held at a predetermined position.

Next, an embodiment in which either the first pin member or the second pin member is manually switched and can be inserted and removed will be described with reference to FIGS. 36 to 38.
FIG. 36 is an external perspective view of the manually-switchable opening / closing fitting 1022 by sliding, and FIGS. 37 and 38 are cross-sectional views taken along arrows XXXVII-XXXVII representing the inside of the box 1050 shown in FIG. is there.

FIG.

  As shown in FIGS. 36 and 37, the opening / closing insertion tool 1022 includes a first pin member 1030 and a second pin member 1040 that can be inserted into and removed from the box 1050, and a first pin member 1030 and a second pin member. A box body 1050 for inserting 1040; and a sliding member 1090 that is slidable in the left-right direction inside a sliding opening 1058 having a rectangular shape in a plan view provided at the center of the front wall 1053 and the rear wall 1054 of the box 1050; It has.

  The lower surface of the sliding member 1090 is a surface that functions as a pin extraction preventing unit 1068 that prevents simultaneous extraction of both the first pin member 1030 and the second pin member 1040. The sliding member 1090 is inserted through the front wall 1053 of the box 1050 and protrudes to the outside of the box 1050, and the user slides the sliding member 1090 left and right in the portion protruding to the outside from the front wall 1053. A sliding operation portion 1091 for performing a dynamic operation is formed. In FIG. 36 and FIG. 37, the description of the pair of left and right engaging teeth and the slider that engages and disengages the engaging teeth is omitted.

  As shown in FIG. 36, in the state where the sliding operation unit 1091 is moved to the right side, the pin member that can be inserted and removed is the first pin member 1030 on the left side on the left side of the sliding operation unit 1091. The insertion / extraction display 1092 for notifying the user of the above is visible. Although not shown in FIG. 36, when the sliding operation unit 1091 is moved to the left side, a pin member that can be inserted / removed on the right side of the sliding operation unit 1091 is a second pin member 1040 on the right side.

This locking portion 1059 is formed at the center of the biasing means 1080 that bends in the vertical direction in order to obtain a predetermined spring constant in the vertical direction shown in FIG. The urging means 1080 has a structure in which both ends are integrally connected to the rear wall 1054 of the box body 1050, and a gap 1082 for bending the urging means 1080 is formed below the urging means 1080.

  By the action of the locking portion 1059, the free action of the sliding member 1090 can be limited, and the sliding member 1090 can be positioned on the left side or the right side. As a result, both the left and right lock claws 1031 and 1041 are simultaneously engaged with the pin removal preventing means 1068 formed on the lower surface of the sliding member 1090, whereby the first pin member 1030 and the second pin Both of the pin members 1040 are prevented from becoming uninsertable. When the sliding member 1090 is slid from the left side to the right side or from the right side to the left side, the locking portion 1059 escapes in the direction of the gap 1082 and is formed on the lower surface of the sliding member 1090. It will slip while contacting the pin pullout prevention means 1068.

  As shown in FIG. 37, when the sliding member 1090 is moved to the right end inside the sliding opening 1058, the lower left end of the sliding member 1090 is in contact with the right root portion of the locking portion 1059. The moving member 1090 is positioned on the right side of the sliding opening 1058. In this state, the pin removal preventing means 1068 on the lower surface of the sliding member 1090 engages with the lock claw 1041 of the second pin member 1040, so that the second pin member 1040 does not come out of the box 1050. On the other hand, the lock claw 1031 of the first pin member 1030 does not engage with the pin removal preventing means 1068 on the lower surface of the sliding member 1090, so that the first pin member 1030 can be inserted into and removed from the box body 1050.

  FIG. 37 shows a sliding port 1058 provided in the rear wall 1054, an urging means 1080, and a gap 1082, and a sliding provided in the front wall 1053 arranged to face each other. Although the drawing of the port 1058 is omitted, the same sliding port 1058, the biasing means 1080, and the gap 1082 are formed on the front wall 1053.

Next, the case where the 2nd pin member 1040 is switched to the state which can be inserted / removed is demonstrated using FIG.
After the first pin member 1030 is inserted into the box 1050 from the state shown in FIGS. 36 and 37, both the first pin member 1030 and the second pin member 1040 are inserted into the box 1050. 36, the sliding operation unit 1091 shown in FIG. 36 is slid to the left. Then, as shown in FIG. 38, the right-side second pin member 1040 can be inserted and removed.

  As shown in FIG. 38, when the sliding member 1090 is moved to the left end inside the sliding opening 1058, the lower right end of the sliding member 1090 comes into contact with the left base portion of the locking portion 1059, and the sliding member 1090 is moved. Is positioned on the left side of the sliding opening 1058. In this state, the pin removal preventing means 1068 on the lower surface of the sliding member 1090 engages with the lock claw 1031 of the first pin member 1030, so that the first pin member 1030 does not come out of the box 1050.

  As described above, when the user moves the sliding operation unit 1091 left and right, the sliding member 1090 is positioned on the left side or the right side, and either the second pin member 1040 or the first pin member 1030 can be inserted and removed. Can be in a state.

  In addition, the latching | locking part 1059 which prevents simultaneous extraction of both the 1st pin member 1030 and the 2nd pin member 1040 is not limited to the Example shown in FIG.37 and FIG.38. For example, as shown in FIG. 39, when engaged with either the hook-shaped lock claw 1231 or the lock claw 1241, the trapezoidal trapezoid formed so as to retract the sliding member 1290 in the direction in which the engaged lock claw exists. Even when the sliding member 1290 having the pin extraction preventing means 1268 having a concave shape is used, simultaneous extraction of both the first pin member 1230 and the second pin member 1240 can be prevented. The sliding member 1290 of the opening / closing insertion tool 1222 slides in the left-right direction inside the sliding port 1258 formed in the center of the front wall (not shown) of the box 1250 and the rear wall 1254.
