Fig. 5 is the embodiment of Embedded Division of lock pawl 41 of insertion section and the second pin parts 40 of lock pawl 31 that is formed at the shared first pin parts 30 of lock pawl Embedded Division 64 of rotatable parts 60.About different with this embodiment, at rotatable parts another embodiment of the special-purpose Embedded Division of the lock pawl of the special-purpose Embedded Division of the lock pawl of the first pin parts and the second pin parts is set respectively, will with Figure 20～Figure 22 in the back paragraph describe.

At the first pin parts 30 of the slide fastener shown in Fig. 5 10 and the second pin parts 40 are inserted into left wall 51, right wall 52, the antetheca 53 (not shown in Fig. 5, with reference to Figure 12) of four faces that form casing 50 downwards and rear wall 54 surrounds and at the spatial portion 57 of the upper opening of casing 50.

Wherein, the first pin parts 30 are inserted into the left insertion groove between left wall 51, antetheca 53, rear wall 54 and the rotatable parts 60 that are formed at casing 50.In addition, the second pin parts 40 are inserted into the right insertion groove that is formed between right wall 52, antetheca 53, rear wall 54 and the rotatable parts 60.Therefore, casing 50 is in the table back of the body direction location of the paper of the left and right directions (in the LR direction shown in Fig. 5) of Fig. 5 and Fig. 5.

In addition; The location of casing 50 relative above-below directions (in UD direction shown in Figure 5) is extracted to stop between mechanism 68 and the box house bottom surface 55 through the pin that is clipped in rotatable parts 60 to the lock pawl 41 of the lock pawl 31 of the first pin parts 30 and the second pin parts 40 and is positioned.Rotatable parts 60 free rotation pivots be bearing in that relative casing 50 clockwise rotates and counterclockwise the twocouese of (in RT direction shown in Figure 5) rotate; But because in the end of the engaging/releasing face 65 of the lock pawl Embedded Division 64 of a part that is formed at rotatable parts 60; The balanced engaging of the lock pawl 31 of the first pin parts 30 and the second pin parts 40 and lock pawl 41 both sides; So under state shown in Figure 5; Even the first pin parts 30 and second pin parts 40 both sides will extract from casing 50, rotatable parts 60 do not rotate yet, and constitute casing 50 and do not sell the mode that parts 40 break away from from the first pin parts 30 and second.

In addition; Near the engagement axis CL of box house bottom surface 55, give prominence to and be the central protuberance 56 of chevron; Having only in the parts 40 either party of the first pin parts 30 or second pin to insert in the state (for example Fig. 3 or state shown in Figure 4) of casing 50, is the protuberance that is used to prevent that pin parts that casing 50 inserts relatively from tilting significantly.In addition, in first and second the side of the opposition side that clips engagement axis CL of respectively selling

parts

30,40, portion 35 is fled from the back side that is formed for making the plug of relative casing 50 and pull head 20 to be easy to concave shape.

In this separation intercalation device, when inserting casing and pull head to the pin parts, or during, be difficult to operative pin parts abreast with said engagement axis CL from casing and pull head pull-off, be mostly to oblique upper or tiltedly below operation.At this moment, because casing and pull head and pin parts are interfered each other, can not smooth and easyly carry out so operate.According to this embodiment, because being set as stated, the back side of concave shape flees from portion 35, so the first pin parts 30 or the second pin parts 40 relative casings and pull head tilt easily, the plug operation of the first pin parts 30 or the second pin parts 40 can easy and smooth and easy carrying out.

Then, be drawn into pull head 20 with casing 50 position contacting, sell the process that parts 30 are extracted from casing 50 to first from state shown in Fig. 5 with Fig. 6 and Fig. 7 explanation.Fig. 6 be expression through left fastener stringer 16 to the top pull-up, from casing 50 first sell the state of parts 30 pull-up L1 figure.Fig. 7 be expression from state shown in Figure 6 further left fastener stringer 16 to the top pull-up, from casing 50 first sell the state of parts 30 pull-up L2 figure.

As shown in Figure 6; When carrying out the first pin parts 30 from the operation of casing 50 pull-ups; Be formed at the lock pawl 31 of engagement axis CL side and engaging/65 engagings of releasing face of the lock pawl Embedded Division 64 that is formed at rotatable parts 60 of the first pin parts, 30 bottoms, rotatable parts 60 are clockwise rotated.

For example, under the state with the first pin parts 30 pull-up L1, the opening direction of lock pawl Embedded Division 64 clockwise rotates average angle θ L1 (in the example of Fig. 6 about 45 °).In addition, be formed at the lock pawl 41 of the engagement axis CL side of the second pin parts, 40 bottoms, engage, so casing 50 does not break away from from the second pin parts 40 because extract prevention mechanism 68 from 64 disengagements of lock pawl Embedded Division and the pin of rotatable parts 60.

As shown in Figure 7, when so that during pull-up first pin parts 30, the lock pawl 31 of the first pin parts 30 leaves from the engaging/releasing face 65 of the lock pawl Embedded Division 64 that is formed at rotatable parts 60.Thus, can extract the first pin parts 30 fully from casing 50 and pull head 20, become state shown in Figure 3.

For example, as shown in Figure 7, when the first pin parts 30 pull-up L2, the opening direction of the lock pawl Embedded Division 64 in the rotatable parts 60 stops at the state that has rotated average angle θ L2 (in example shown in Figure 7 about 135 °).In this state, because also extracting with the pin of rotatable parts 60, the lock pawl 41 of the second pin parts 40 stop mechanism 68 to engage, thus can not extract the second pin parts 40 from casing 50, thereby casing 50 can not break away from from the second pin parts 40.

Then; From pulling down the state of the first pin parts 30 fully; When selling parts 30 to pull head 20 and casing 50 insertions to first, engaging/65 engagings of releasing face of the lock pawl 31 of the first pin parts, 30 bottoms and the lock pawl Embedded Division 64 that is formed at rotatable parts 60 becomes state shown in Figure 7.When so again the first pin parts 30 when leaving behind, lock pawl 31 pressing fastened/releasing faces 65 can make rotatable parts 60 rotate counterclockwise, and the first pin parts 30 are descended.And then, when proceeding the first pin parts 30, transfer to state shown in Figure 6 to operation that casing 50 is pushed, can be inserted into the first pin parts 30 position of inner bottom surface 55 butts of the leading section that makes the first pin parts 30 and casing 50.

In addition; In state shown in Figure 6; The opening direction of the lock pawl Embedded Division 64 in the rotatable parts 60 stops at the state that has rotated average angle L1, keeps this state, and the lock pawl 41 of the second pin parts 40 remains on the pin of rotatable parts 60 and extracts the state that stops mechanism 68 to engage.Therefore, under this state, can not extract the second pin parts 40 from casing 50.

Therefore, be necessary that a rotatable parts 60 further rotate counterclockwise angle L1, make rotatable parts 60 turn back to the neutral position.About making these rotatable parts 60 return the mechanism of neutral position, use Figure 16 paragraph afterwards to describe.At this, at first the global shape to rotatable parts 60 describes with Fig. 8 and Fig. 9, and the face shaping of selling parts 40 about the first pin parts 30 and second describes with Figure 10 and Figure 11.

Fig. 8 is the figure with the shape of side view and sectional views rotatable parts 60.In addition, Fig. 9 is the stereogram of rotatable parts 60.

A-A shown in Figure 8 is to be used to support the rotate cutaway view of the axial region 66 that moving axis RC freely rotates of rotatable parts 60 to view and E-E to view.As shown in Figure 8; Axial region 66 is formed at the two ends of rotatable parts 60; Through inserting the antetheca 53 (with reference to Figure 12) of the table back of the body that is formed at casing 50 and the bearing 58 (with reference to Figure 12) of rear wall 54 (with reference to Figure 12) inner face to this axial region 66, rotatable parts 60 rotate moving axis RC free rotation ground supporting on casing 50.

In addition, extract in the prevention mechanism 68, form two plane bearing holding divisions 67 at the pin of axial region 66.This bearing holding division 67 is through engaging the parts that come limit rotation parts 60 to rotate with the axle holding division 59 of the inner peripheral surface that is formed at casing 50 middle (center) bearings 58.In the embodiment shown in fig. 8, two bearing holding divisions 67 are mutually orthogonal, and relative neutral axis Z-Z is line and forms symmetrically.In addition, about the effect of bearing holding division 67, with Figure 18 and Figure 19 after state.

B-B shown in Figure 8 is that expression is used to make the lock pawl 31 or second of the first pin parts 30 to sell the cutaway view of lock pawl 41 shapes that insert, lock pawl Embedded Division 64 of parts 40 to view and D-D to view.As shown in Figure 8, lock pawl Embedded Division 64 relative neutral axis Z-Z are line and form symmetrically.At lock pawl Embedded Division 64, form through engage with lock pawl 31 and lock pawl 41, in order to sell the first pin parts 30 and second in engaging/releasing face 65 (about acting on) that rectilinear motion that parts 40 carry out converts the rotational motion of rotatable parts 60 to reference to Fig. 5～7.

C-C shown in Figure 8 is that expression is rotated the cutaway view that rotates the shape of the neutral rotating cam 62 that engages with protuberance 44 with the neutral position of the protuberance 34 or the second pin parts 40 with the neutral position of the first pin parts 30 to view.As shown in Figure 8, neutral rotating cam 62 relative neutral axis Z-Z lines are formation symmetrically.Effect about this neutrality rotating cam 62 describes with Figure 16 and Figure 17 paragraph afterwards.

In addition, the position of cutting plane C-C is the intermediate point of the turning cylinder RC (turning cylinder at the center of the axial region 66 through both sides) of rotatable parts 60, and the intermediate point of the turning cylinder RC of pair of locking pawl Embedded Division 64 relative these rotatable parts 60 is symmetrically formed.Therefore, insert lock pawl Embedded Division 64 to lock pawl 31 or lock pawl 41, when rotatable parts 60 are rotated, owing to apply impartial power, so can the smooth and easy rotation of carrying out rotatable parts 60 at both sides' axial region 66.

In addition; Because neutral rotating cam 62 is formed at the intermediate point of the turning cylinder RC of rotatable parts 60; So with the neutral position rotate with protuberance 34 or neutral position rotation with protuberance 44 engage, when turning to the neutral position to rotatable parts 60; Because the axial region 66 both sides also applies impartial power, so also can make rotatable parts 60 turn to the neutral position swimmingly.

Figure 10 is the stereogram of detail shape of the first pin parts 30 of the expression lower end that is installed in left fastener stringer 16, and Figure 11 is the stereogram of detail shape of the second pin parts 40 of the expression lower end that is installed on right fastener stringer 17.

Shown in figure 10, in the bottom of the first pin parts 30, identical shaped lock pawl 31 forms two arranged side by side.These two lock pawls 31 are the parts that are used for inserting respectively lock pawl Embedded Division 64 shown in Figure 8.Forming identical shaped lock pawl 31 and lock pawl Embedded Division 64 at two places, is for the axial region 66 at two places at rotatable parts 60 two ends applies uniform power, the rotation that makes rotatable parts 60 cause smoothly.

In addition; Above the pars intermedia of the lock pawl 31 that forms at two places of first pin parts 30 bottoms, be formed be used on the back segment rank of inserting the first pin parts 30 casings 50, through the neutral position rotation that engages with the neutral rotating cam 62 (with reference to Fig. 8) of rotatable parts 60, turn to the neutral position to rotatable parts 60 with protuberance 34.

Equally, shown in figure 11, in the bottom of the second pin parts 40, identical shaped lock pawl 41 forms two arranged side by side.These two lock pawls 41 are the parts that are used for inserting respectively two lock pawl Embedded Divisions 64 shown in Figure 8.In addition; Above the pars intermedia of the lock pawl 41 that is formed at second pin two places, parts 40 bottoms, be formed be used on the back segment rank of inserting the second pin parts 40 casings 50, through the neutral position rotation that engages with the neutral rotating cam 62 (with reference to Fig. 8) of rotatable parts 60, turn to the neutral position to rotatable parts 60 with protuberance 44.

Then, with Figure 12 the shape of casing 50 is described.The stereogram of Figure 12 state that to be expression decomposed assembled box body 50.

Shown in figure 12; Casing 50 is made up of table casing 50F and lining casing 50R; Table casing 50F is formed with antetheca 53, left wall 51, right wall 52, box house bottom surface 55 and central protuberance 56, and lining casing 50R is formed with rear wall 54, left wall 51, right wall 52, box house bottom surface 55 and central protuberance 56.

The antetheca 53 of table casing 50F and in the central portion of casing 50R, form the bearing 58 of pivot suspension face cylindraceous with the axial region 66 that is used for pivot suspension rotatable parts 60.On the top of the pivot suspension face of this bearing 58, be formed for through engage the plane axle holding division 59 of the rotation action of coming limit rotation parts 60 with bearing holding division 67 shown in Figure 8.Because this holding division 59 is formed at the outside of external diameter of the axial region 66 of rotatable parts 60, so can be inserted into the axial region 66 of rotatable parts 60 in the bearing 58, bearing 58 supports axial region 66 free to rotately.

Table casing 50F and in the composition surface 70 of casing 50R, the outstanding stop member 71 that forms.Be opened in the stop aperture 72 on identical composition surface 70 through inserting this stop member 71, can keep location and the joint of table casing 50F and lining casing 50R.Table casing 50F and under the situation of casing 50R by ester moulding, when associative list casing 50F and lining casing 50R, can adopt bonding or ultrasonic bonding.In addition, table casing 50F and under the situation of casing 50R by metal forming, table casing 50F and lining casing 50R can adopt bonding or soldering engages.

Figure 13 representes another embodiment of casing.

Casing 150 shown in Figure 13 is the casings that formed by a phantom with different in the mode that is made up of table casing 50F and these two parts of lining casing 50R shown in Figure 12.In casing shown in Figure 12 50; After inserting bearing 58 to the axial region 66 of rotatable parts 60; Engage through showing casing 50F and lining casing 50R, can be by bearing 58 pivot suspension axial regions 66, but shown in casing among Figure 13 150; When integrally formed antetheca 53 (not shown) and rear wall 54, need be used for the research of inserting bearing 58 to the axial region 66 of rotatable parts 60.

In the embodiment shown in fig. 13, insert axial region 66 easily, form the bearing importing portion 157 of the thickness attenuation that makes antetheca 53 and rear wall 54 for part in the top of the bearing 58 of antetheca 53 (with reference to Figure 14) and rear wall 54.And then, for through pushing axial region 66 downwards, enlarge antetheca 53 and rear wall 54 laterally, insert bearing 58 to axial region 66 along this bearing importing portion 157, form and import inclined plane 159.

Cross over 159 completion of importing inclined plane under the situation of the insertion of the recess that forms bearing 58 at axial region 66, antetheca 53 and rear wall 54 return original position from expanded, and be shown in figure 14, is maintained in the state that axial region 66 is inserted into the recess that forms bearing 58.

Figure 14 representes that the axial region 66 that is formed at rotatable parts 60 two ends is inserted into sectional block diagram state, casing 150 that is formed at 150 liang of bearings of locating 58 of casing.

Shown in figure 14, above the bearing 58 of antetheca 53 and rear wall 54, form bearing importing portion 157, thereunder form and import inclined plane 159.Shown in figure 14, in case when axial region 66 was inserted into the recess that forms bearing 58, antetheca 53 and rear wall 54 returned original position from expanded, keep axial region 66 and are inserted into the state in the recess that forms bearing 58.Therefore, rotatable parts 60 relative casings 150 are freely to rotate by pivot suspension.

Then, with the function of Figure 15 illustrative at each position of each positions of the first pin parts 30 shown in each positions of the rotatable parts shown in Fig. 8 60, Figure 10 and the second pin parts 40 shown in Figure 11.

Figure 15 is that explanation is formed with the Bearning mechanism of rotatable parts 60 and rotates the key diagram place, that separate intercalation device 22 of neutral rotating mechanism portion of disengaging and preventing organization portion and the rotatable parts 60 of anti-locking mechanism portion, casing 50 and pin parts.

In Figure 15, the state that is divided into Bearning mechanism and rotates the 50B of disengaging and preventing organization portion, 50D and the neutral rotating mechanism 50C of portion of the anti-50A of locking mechanism portion, 50E, pin parts is dissectd casing 50 in expression.For the first pin parts 30, the state of the 30B of disengaging and preventing organization portion, 30D and the neutral rotating mechanism 30C of portion that are divided into the pin parts is dissectd in expression.For the effect of the 30B of disengaging and preventing organization portion of pin parts, 30D such as Fig. 5～shown in Figure 7.

In addition, the effect for the neutral rotating mechanism 50C of portion describes with later Figure 16 and Figure 17.In addition, prevent the 50A of locking mechanism portion, 50E, describe with Figure 18 and Figure 19 for bearing and rotation.

At first, mechanism when inserting pin parts 30 from state shown in Figure 6, that be used for returning rotatable parts 60 the rotating mechanism 50C of the portion neutral position, neutral describes with Figure 16.

Figure 16 is that the L-L of slide fastener 10 shown in Figure 2 is to view.As shown in Figure 6, when inserting casing 50 to the first pin parts 30, the lower end of the first pin parts 30 and the size between the box house bottom surface 55 are become below the L1, then lock pawl 31 leaves from lock pawl Embedded Division 64.Therefore, can not be below the neutral position be made as angle θ L1 (the example of Figure 16, being about 45 °) the angle of the average opening direction of the lock pawl Embedded Division 64 in the rotatable parts 60.

Therefore; Shown in figure 16; Rotatable parts 60 form neutral rotating cam 62 further leave behind simultaneously the first pin parts 30, make lock pawl 31 when lock pawl Embedded Division 64 leaves, the neutral position rotation that is used for neutral rotating cam 62 butts turning to the neutral position to rotatable parts 60 with protuberance 34 be formed at down first sell parts 30 engagement axis CL side.

Thus, when further leaving behind the first pin parts 30 from state shown in Figure 16, rotate with protuberance 34 and neutral rotating cam 62 butts the neutral position, and rotatable parts 60 are rotated counterclockwise.Describe with Figure 17 for the first pin parts 30 later state of further leaving behind.

To be expression sell the figure of state that parts 40 are inserted into the depths of casing 50 to the first pin parts 30 and second of slide fastener 10 to Figure 17, and the L-L that is Fig. 2 is to view.When the state from Figure 16 inserts casing 50 to the first pin parts 30 fully; Shown in figure 17; Because the neutral position is rotated with protuberance 34 and neutral position and is rotated with protuberance 44 and neutral rotating cam 62 butts; So rotatable parts 60 are positioned at the position (neutral position) that relative engagement axis CL is the line symmetry.

Shown in figure 17; Be positioned at rotatable parts 60 under the situation of neutral position; Because the engaging of lock pawl 41 both sides and the lock pawl Embedded Division 64 of the lock pawl 31 of the first pin parts 30 and the second pin parts 40/releasing face 65 balancedly engage, sells parts 40 disengagings so casing 50 is not sold parts 30 and second from first.

In addition; The insertion first pin parts 30 have been described in Figure 16 and Figure 17 and have been turned to the neutral position to rotatable parts 60; But because lock pawl 31 use protuberance 34 and neutral position to rotate to use protuberance 44 with lock pawl 41, neutral position rotation is to mesh the shape of axis CL as the line symmetry relatively, and rotatable parts 60 also are to mesh the shape that axis CL is the line symmetry relatively, so; Even under the situation of inserting the second pin parts 40, also can turn to the neutral position to rotatable parts 60.

In addition; Among Fig. 5～Fig. 7 in front; As it is such to plug first explanation of pin during parts 30, and the lock pawl 31 of the first pin parts 30 and neutral position rotate that to rotate with the protuberance 44 relative axis CL that mesh with the lock pawl 41 of protuberance 34 and the second pin parts 40 and neutral position are the symmetrical shapes of line.In addition, in the state of Fig. 5, because rotatable parts 60 also are the shapes that meshes axis CL line symmetric figure relatively, so the relative too casing 50 of the second pin parts 40 can plug.

Then, with Figure 18 and Figure 19 Bearning mechanism and rotation are prevented that locking

mechanism

50A, 50E describe.

Figure 18 is that the first pin parts 30 and the second pin parts 40 of expression slide fastener 10 insert the depths of casing 50, the figure that rotatable parts 60 are positioned at the situation of neutral condition.In addition, Figure 18 is that the M-M of Fig. 2 is to view.Figure 19 representes that pulling down first of slide fastener 10 from casing 50 sells parts 30, only sells the figure that parts 40 insert the state of casings 50 to second.Figure 19 and Figure 18 are same, and the M-M that is Fig. 2 is to view.

In state shown in Figure 180; Because lock pawl 41 both sides of the lock pawl 31 of the first pin parts 30 and the second pin parts 40 engage/65 engagings of releasing face with the lock pawl Embedded Division 64 that is formed at rotatable parts 60, so the first pin parts 30 and second pin parts 40 both sides can not pull down from casing 50 simultaneously.But; Through in the pull-up first pin parts 30 or the second pin parts 40 either party; Can make lock pawl 31 or lock pawl 41 insert lock pawl Embedded Divisions 64, rotatable parts 60 are rotated, can in the first pin parts 30 or the second pin parts 40 either party be extracted.

Like Fig. 5～shown in Figure 7, when the first pin parts 30 were extracted, rotatable parts 60 clockwise rotated.In addition, when the second pin parts 40 were extracted, rotatable parts 60 rotated counterclockwise.At rotatable parts 60 during the neutral condition rotational angle θ L3 (with reference to Figure 19); Because the axial region 66 of the drum in the rotatable parts 60 contacts with axle holding division 59; So rotatable parts 60 can be extracted the first pin parts 30 or the second pin parts 40 freely in bearing 58 inner rotation.Thereafter the bearing 58 in the situation of extracting about in the parts 40 either party of the first pin parts 30 or second pin and the relation of axial region 66 describe with following Figure 19.

In state shown in Figure 19, the first pin parts 30 are extracted fully, and casing 50 becomes the state that hangs down from the second pin parts 40.In this state, the possibility that on the direction of drawing back the second pin parts 40 and casing 50, applies power is high.

That kind of embodiment shown in figure 19; When in the parts 40 either party of the first pin parts 30 or second pin extracts; In order to prevent in advance more than the rotatable parts 60 rotational angle θ L3 or can not be the undesirable condition that the lock pawl 31 of the first pin parts 30 inserts in the lock pawl Embedded Divisions 64 or the second pin parts 40 are thrown off from casing 50 owing to turn back to below the angle θ L3; Make the

axle holding division

59 and 67 engagings of bearing holding division, the rotation of limit rotation parts 60 of a part that is formed at bearing 58.

Thus, even when on the direction of drawing back the second pin parts 40 and casing 50, applying power, also can continue to make the lock pawl 41 of the second pin parts 40 to extract prevention mechanism 68 and engage with the pin of rotatable parts 60.In addition, can prevent that casing 50 breaks away from from the second pin parts 40.In addition, the lock pawl Embedded Division 64 of rotatable parts 60 can be remained on the position of easy insertion lock pawl 31.

In addition; In the embodiment shown in Figure 18 and Figure 19; Bearing holding division 67 be formed on relative lock pawl Embedded Division 64 average opening direction (shown in Figure 19, angle θ L3) respectively have the position at 45 ° phase angle, but also can be formed at the position at phase angle with 30 °～60 °.

From state shown in Figure 19, when inserting pull head 20 and casing 50 to the first pin parts 30, the lock pawl 31 of the first pin parts 30 embeds lock pawl Embedded Division 64, the power that effect rotates counterclockwise it when pushing lock pawl Embedded Division 64 downwards.When pushing rotatable parts 60 downwards and it rotated counterclockwise; Because being formed at the bearing holding division 67 of axial region 66 breaks away from from axle holding division 59; Become axial region 66 and contact, so rotatable parts 60 free to rotately by pivot suspension, rotate to the neutral position with the below of bearing 58.Then, casing 50 inserts the first pin parts 30 relatively.

In addition; In state shown in Figure 19, the state that inserts the second pin parts 40 is illustrated, but because the shape of the shape of the leading section shape of the first pin parts 30 and the second pin parts 40, casing 50 and rotatable parts 60 is to mesh the shape that axis CL is the line symmetry relatively; Even so only inserting the first pin parts 30 in the state of casing 50; Same with above-mentioned situation, also can be through the engaging of axle holding division 59 and bearing holding division 67, the rotation of limit rotation parts 60.

Embodiment 2

Then, with Figure 20～Figure 22 another embodiment of separation intercalation device of the present invention is described.Figure 20～Figure 22 is the figure of the embodiment of explanation lock pawl Embedded Division 264R that special-purpose lock pawl Embedded Division 264L of the lock pawl 231 of first pin in the parts 230 and lock pawl 241 special uses in the second pin parts 240 independently are set respectively on rotatable parts 260.Same with above-mentioned Fig. 5; Figure 20 is the cutaway view of the slide fastener 210 that dissects of side nearby of the first pin parts 230 and the second pin parts 240, is to be illustrated in casing 250 to embed the figure that the first pin parts 230 and second pin parts 240 both sides, rotatable parts 260 stop at the state of neutral position.

The first pin parts 230 of slide fastener 210 shown in Figure 20 and the second pin parts 240 are embedded in by left wall 251, right wall 252, the antetheca (not shown at Figure 20) of four faces that form casing 250 and rear wall 254 surrounds and in the spatial portion 257 of the upper opening of casing 250.

Because the first pin parts 230 are embedded in the left embedded groove of left wall 251, antetheca,

rear wall

254 and 260 formation of rotatable parts of casing 250.In addition, the second pin parts 240 are embedded in the right embedded groove of right wall 252, antetheca,

rear wall

254 and 260 formation of rotatable parts, so casing 250 is located on the table back of the body direction of the paper of the left and right directions (in LR direction shown in Figure 20) of Figure 20 and Figure 20.

In addition, the location of casing 250 relative above-below directions (the UD direction shown in Figure 20) positions through being clipped in the lock pawl 241 of the lock pawl 231 of the first pin parts 230 and the second pin parts 240 between rotatable parts 260 and the box house bottom surface 255.Casing 250 is not fixed in any one that the first pin parts 230, second are sold in parts 240, left fastener stringer 216 and the right fastener stringer 217, but can not throw off from the first pin parts 230 or the second pin parts 240.

Rotatable parts 260 relative casings 250 are reaching counterclockwise (the RT direction of Figure 20) twocouese clockwise freely to rotate by pivot suspension.At the lock pawl 231 of engaging/releasing face 265L engaging first pin parts 230 of the lock pawl Embedded Division 264L of a part that is formed at rotatable parts 260, sell the lock pawl 241 of parts 240 in engaging/releasings face 265R engaging second of lock pawl Embedded Division 264R.For this reason, at state shown in Figure 20, even the first pin parts 230 and second pin parts 240 both sides will extract from casing 250, rotatable parts 60 can not rotate, and constitute the mode that the first pin parts 230 and second pin parts 240 both sides can not break away from from casing 250.

Then, use Figure 21 and Figure 22 that the process of pulling down the first pin parts 230 from casing 250 is described.

Figure 21 is that expression is through clockwise rotating the figure of 45 ° state from the neutral position from the state pull-up shown in Figure 20 first pin parts 230, rotatable parts 260.Figure 22 is expression further clockwise rotates 90 ° state from the neutral position to the top pull-up first pin parts 230, rotatable parts 260 from state shown in Figure 21 figure.

Then, in Figure 23～Figure 28 the expression be formed at the bearing holding division of rotatable parts and be formed at casing the axle holding division another embodiment.

Figure 23 is the stereogram that expression separates the embodiment of intercalation device 322, and this separation intercalation device 322 has the force application mechanism 380 to axle holding division 359 application of forces that are formed at casing 350 the bearing holding division 367N that is formed at rotatable parts 360.Casing 350 at the separation intercalation device 322 shown in this figure dots for convenience of description.In addition, omit the slide fastener cotton yarn tape of left fastener stringer of narration and right fastener stringer, only put down in writing the first pin parts 30 and the second pin parts 40.

Figure 24 is the stereogram of expression with the state of the central portion of the casing 350 in the rectangular section cut-out of the pivot center of the relatively rotating parts 360 separation intercalation device 322 shown in Figure 23, is that expression is the figure of the state of the bearing 358 (with reference to Figure 25) of rotatable parts 360 insertion casings 350.

Figure 25 removes rotatable parts 360, sees the figure that bearing 358, axle holding division 359 and force application mechanism storage part 382 ground show easily from the casing shown in Figure 24 350.In addition, Figure 26 be represent further pivot center with rotatable parts 360 cut off casing shown in Figure 24 350 abreast, at the figure of the state of force application mechanism storage part 382 setting-in force application mechanisms 380.

State shown in Figure 23 is to sell the state that parts 40 both sides insert the spatial portion of casing 350 to the first pin parts 30 and second, is the state that rotatable parts 360 are present in the neutral position.In the embodiment of Figure 23; Be present in the situation of neutral position at rotatable parts 360; In order to keep its neutral position, form the bearing holding division 367N (with reference to Figure 27 of subsequent paragraphs) of the rotation action that hinders rotatable parts 360 in the part of the pivot suspension face of axial region 366.

In addition; Same with state shown in Figure 19; Even extracting the first pin parts 30 or the second pin parts 40 from casing 350, having only either party pin parts to insert the state of casing 350; In order to hinder the rotation action of rotatable parts 360, form bearing holding division 367 (Figure 28 of paragraph describes this effect in the back) in the part of the pivot suspension face of axial region 366.

Like Figure 23～shown in Figure 26, axial region 366 pivot suspensions of rotatable parts 360 are at the bearing 358 of antetheca that is formed at casing 350 and rear wall.In addition, the tabular force application mechanism 380 of rotatable parts 360 to the top application of force left in the force application mechanism storage part 382 of casing 350.Force application mechanism storage part 382 is the grooves that are to become the V-shape of protrusion with bearing 358 rightabouts, force application mechanism 380 to above during to rotatable parts 360 application of forces, form force application mechanism 380 deflections.As the material of force application mechanism 380, can use spring steel material, copper alloy and other material.

Then, with Figure 27 the state that rotatable parts 360 remain on the neutral position is described.

Figure 27 is a cutaway view in bearing 358 parts of casing 350, rotatable parts 360 and force application mechanism 380, is the cutaway view with the face of the pivot center quadrature of rotatable parts 360.

Shown in figure 27, deposit in force application mechanism 380 in the force application mechanism storage part 382 the axial region 366 of the rotatable parts 360 that are present in the neutral position to its axle center application of force.Like this; Owing to be formed at the plane axle holding division 359 that the plane bearing holding division 367N of a part of the pivot suspension face of axial region 366 pushes the part of the pivot suspension face that is formed at bearing 358, so bearing holding

division

367N and 359 engagings of axle holding division.Like this, restriction is present in the rotation of the rotatable parts 360 of neutral position, is held in the neutral position with trying hard to keep of regulation.

When the user extracted either party operation in the parts 40 of the first pin parts 30 or second pin, plane bearing holding division 367N left from the axle holding division 359 of same level shape, and axial region 366 carries out the motion that axle holding division 359 relatively slides.At this moment, owing to rotatable parts 360 move to the below shown in this figure a little, so axial region 366 pushes away force application mechanism 380, the deflection downwards of the central portion of force application mechanism 380 downwards down.

Then, describe extract the first pin parts 30 or second pin either party state the parts 40 from casing 350 with Figure 28.In addition, Figure 28 uses the section identical with Figure 27 to cut off the figure of casing 350.

Shown in figure 28, when extracting the first pin parts 30 from casing 350, rotatable parts 360 rotate the angle of θ L3 from neutral condition.In this state, force application mechanism 380 is axial region 366 application of forces to rotatable parts 360 to the axle center also.At this moment; Owing to be formed at the plane axle holding division 359 that the plane bearing holding division 367 of a part of the pivot suspension face of axial region 366 is pushed the part of the pivot suspension face that is formed at bearing 358, so bearing holding

division

367 and 359 engagings of axle holding division.Therefore, the rotation of limit rotation parts 360 remains in this position.

Like this; In extracting the first pin parts 30 or second pin either party state in the parts 40, it is above or owing to turn back to that the lock pawl 31 that causes the first pin parts 30 below the angle θ L3 can not embed in the lock pawl Embedded Division 64 or second sell parts 40 and come off from casing 350 to prevent in advance that rotatable parts 360 from rotating the angle of θ L3.In addition, the lock pawl Embedded Division 64 (with reference to Figure 24) that is formed at rotatable parts 360 can be remained on the position of easy embedding lock pawl 31.

When the user inserts when operation to the first pin parts of having extracted 30 again from state shown in Figure 28, plane bearing holding division 367 leaves from the axle holding division 359 of same level shape, and axial region 366 carries out the motion that axle holding division 359 relatively slides.This moment, rotatable parts 360 also descended to the below shown in this figure, and pushed away force application mechanism 380 downwards down through axial region 366, the deflection downwards of the central portion of force application mechanism 380.

Like this, rotatable parts 360 be present in the situation of neutral position extracted the first pin parts 30 or the second pin parts 40 in either party situation under, can play the effect of the rotation action that hinders rotatable parts 360.

Embodiment 4

Then, represent to have the bearing holding division that is formed at rotatable parts and be formed at another embodiment of separation intercalation device of the axle holding division of casing at Figure 29.

In the embodiment of Figure 23～shown in Figure 28, represented as the bearing holding division 367N that is formed at rotatable parts 360 to the force application mechanism 380 of axle holding division 359 application of forces that are formed at casing 350, used the embodiment of the force application mechanism 380 of the parts of opening in 350 minutes with casing.Figure 29 is the embodiment at the separation intercalation device 422 of a part of integrally formed force application mechanism 480 of casing 450.In addition, Figure 29 is same with Figure 27 of previous explanation, is rotatable parts 360 and the cutaway view of force application mechanism 480 in bearing 458 parts of casing 450.In addition, rotatable parts 360 are same with Figure 27, and expression is present in the state of neutral position.

Shown in figure 29, the bearing 458 of casing 450 is the axial region 366 of pivot suspension rotatable parts 360 freely to rotate.480 pairs of force application mechanisms are formed at the bearing holding division 367N of rotatable parts 360 to axle holding division 459 application of forces that are formed at casing 450.

In addition, shown in figure 29, for the spring constant that obtains stipulating, form the formation at two ends that connects and composes the force application mechanism 480 of fabric width with casing 450 one, in the space 482 that is formed for making force application mechanism 480 deflections up and down of force application mechanism 480.

Effect through force application mechanism 480; Owing to be formed at the plane axle holding division 459 that the plane bearing holding division 367N of a part of the pivot suspension face of axial region 366 pushes the part of the pivot suspension face that is formed at bearing 458, so bearing holding division 367N and 459 engagings of axle holding division.Like this, restriction is present in the rotation of the rotatable parts 360 of neutral position, is held in the neutral position with trying hard to keep of regulation.

When the user extracted either party operation in the parts 40 of the first pin parts 30 or second pin, plane bearing holding division 367N left from the axle holding division 459 of same level shape, and axial region 366 carries out the motion that axle holding division 459 relatively slides.At this moment, owing to rotatable parts 360 move to the below of this figure a little, so axial region 366 pushes away force application mechanism 480, the deflection downwards of the central portion of force application mechanism 480 downwards down.

Extract the first pin parts 30 or second pin either party state the parts 40 from casing 450 under, rotatable parts 360 rotate about 135 ° (the angle θ L3 that Figure 28 shows) from neutral condition.In this state, force application mechanism 480 the axial region 366 of rotatable parts 360 to the axle center application of force.Like this; Owing to be formed at the plane axle holding division 459 that the plane bearing holding division 367 of a part of the pivot suspension face of axial region 366 is pushed the part of the pivot suspension face that is formed at bearing 458, so bearing holding division 367 and 459 engagings of axle holding division.Therefore, the rotation of limit rotation parts 360 is held with the power of stipulating.

Like this; In extracting the first pin parts 30 or second pin either party state in the parts 40, can prevent in advance that rotatable parts 360 from rotating more than 135 ° or owing to turn back to that the lock pawl 31 that causes the first pin parts 30 below 135 ° can not embed in the lock pawl Embedded Division 64 or second sell the undesirable condition that parts 40 are deviate from from casing 450.In addition, the lock pawl Embedded Division 64 (with reference to Figure 24) that is formed at rotatable parts 360 can be remained on the position of easy embedding lock pawl 31.

When the user inserted 30 operations of the first pin parts again from extracting the first pin parts, 30 states, plane bearing holding division 367 left from the axle holding division 459 of same level shape, and axial region 366 carries out the motion that relative axle holding division 459 slides.This moment, rotatable parts 360 also descended downwards, pushed away force application mechanism 480, the deflection downwards of the central portion of force application mechanism 480 downwards down through axial region 366.

Like this, rotatable parts 360 be present in the situation of neutral position extract the first pin parts 30 or either party situation of second pin in the parts 40 under, can play the effect of the rotation action that hinders rotatable parts 360.
