As shown in Figure 1 and Figure 2, be provided with in the end of the above-below direction of the chain denture 15 of slide fastener 10 as lower stop member 44 and upper stop member 46, this lower stop member 44 and upper stop member 46 stop the slip of pull head 18 and limit slide fastener 10, thus pull head 18 can not be departed from from chain denture 15.
Pull head possesses upper flange 20, lower wing plate 22 and links the not shown link post of upper flange 20 and lower wing plate 22.In addition, there is pair of flanges to give prominence to towards direction each other at the left and right lateral margin of upper flange 20 and lower wing plate 22, between each flange of upper flange 20 and lower wing plate 22, there is the gap can inserting tape member 16.Link the upper end, strip length direction that post links upper lower wing plate 20,22, between upper flange 20 and lower wing plate 22, be formed with the chain tooth path of navigation of roughly Y-shaped.
In addition, at upper flange 20, pulling-on piece 21 being installed, by operating this pulling-on piece 21, can making to be engaged with each other or engagement releasing by the adjacent chain tooth 14 of chain tooth path of navigation.In addition, as shown in Figure 6, the mode that each chain tooth 14 becomes upper flange 20 side with chain tooth outward appearance portion 34, engaging piece 36 becomes lower wing plate 22 side is inserted through.
The chain tooth 14a of lower stop member 44 and bottom separates small interval and is installed on the end of the downside of chain denture 15, under the state engaged making a pair chain denture 15, be fixed with the state that the sidepiece 16a of a pair tape member 16 is closed each other, be commonly referred to as lower stop member.Lower stop member 44 is that the synthetic resin of use and chain tooth 14 same material is formed by injection moulding.As shown in Figure 5, Figure 6, be provided with in lower stop member 44: lower stop member outward appearance portion 48, it is configured in the surperficial 16c of tape member 16; And lower stop member back 50, it is configured in the back side 16d of tape member 16.In injection moulding when the sidepiece 16a of tape member 16, between lower stop member outward appearance portion 48 and lower stop member back 50, the length direction along tape member 16 is through and be formed with pair of right and left band holddown groove 52.
Observe from the surperficial 16c of tape member 16, the lower stop member outward appearance portion 48 of lower stop member 44 is shapes almost identical with the chain tooth outward appearance portion 34 of chain tooth 14, thin generally elliptical shape is formed as at the width orthogonal with the length direction of tape member 16, and in the width orthogonal with the length direction of tape member 16 shape symmetrically.Thus, when pair of right and left chain tooth 14 engages, the chain tooth outward appearance portion 34 that the lower stop member outward appearance portion 48 of lower stop member 44 is positioned at multiple chain tooth 14 arranges on the extended line that configures in a row with chain form, and the lower stop member outward appearance portion 48 of lower stop member 44 is also identical with the shape in chain tooth outward appearance portion 34, stop member 44 is therefore descended to merge with chain denture 15 and integrated.
The full-size of the width of lower stop member 44 is more bigger than the full-size of the width of chain tooth 14.But due to central shaft and the central axis of width of chain denture 15 being arranged in row of the width of lower stop member 44, lower stop member 44 merges with chain denture 15 and integrated.
It is roughly hemispherical that the cross sectional shape of the thickness direction at tape member 16 in lower stop member outward appearance portion 48 and the chain tooth outward appearance portion 34 of chain tooth 14 are made like as integrally bending, and the mode that the width core in following stop member outward appearance portion 48 becomes maximum height apart from the height on the surface of tape member 16 sets.The lower stop member back 50 of lower stop member 44 is generally elliptical shape identical with lower stop member outward appearance portion 48, the mode that the bending roughly hemispheric width core at following stop member back 50 becomes maximum height apart from the height at the back side of tape member 16 sets, and the lower surface at lower stop member back is provided with the planar portions 53 parallel relative to the back side 16d of tape member 16.
As shown in Figure 6, the length a (maximum height) from the surperficial 16c of tape member 16 to the highest point in lower stop member outward appearance portion 48 of lower stop member 44 arranges to obtain △ a longer than the length c of the medial surface 18a of upper flange 20 side from the surperficial 16c of tape member 16 to pull head 18.The highest point from the back side 16d of tape member 16 to lower stop member back 50 of lower stop member 44 and the length b (maximum height) of planar portions 53 arrange to obtain △ b longer than the length d of the medial surface 18b of lower wing plate 22 side from the back side 16d of tape member 16 to pull head 18.In addition, the relation of △ b and △ a meets: △ b > △ a.
As shown in Figure 1 and Figure 2, upper stop member 46 is installed on the end of the upside of side's chain denture 15 of tape member 16, upper stop member 46 be arranged at have in a pair chain denture 15 for from the tape member 16 of chain tooth 14b of the 2nd.That is, upper stop member 46 is only fixed on the lateral margin of the tape member 16 of a side, and the chain tooth 14 of upper end of upper stop member 46 towards the tape member being positioned at the opposing party from the lateral margin of the tape member 16 of a side is extended.
Upper stop member 46 with from upper the 2nd, namely and separate small interval as the chain tooth 14b of upper end of the tape member 16 being provided with upper stop member 46 side and be mounted.And make chain denture 15 intermesh, pull head 18 is positioned near the upper end of chain denture 15, and can see the state not having chain tooth 14b, 14c of engaging from the upper end of pull head 18, upper stop member 46 and highlands such as being positioned at chain tooth 14c topmost arrange.
Upper stop member 46 uses the synthetic resin with chain tooth 14 same material, formed by injection moulding.As shown in Figure 7, Figure 8, be provided with in upper stop member 46: upper stop member outward appearance portion 54, it is configured in the surperficial 16c of tape member 16; And upper stop member back 56, it is configured in the back side 16d of tape member 16.In injection moulding when the sidepiece 16a of tape member 16, between upper stop member outward appearance portion 54 and upper stop member back 56, the length direction along tape member 16 is through and be formed with pair of right and left band holddown groove 57.
Observe from the surperficial 16c of tape member 16, the upper stop member outward appearance portion 54 of upper stop member 46 is almost identical with chain tooth outward appearance portion 34 shape of chain tooth 14, be formed as thin generally elliptical shape on the width orthogonal with the length direction of tape member 16, and at the length direction of tape member 16 and with the orthogonal width shape symmetrically of length direction.Thus, pair of right and left chain tooth 14 engages, and when pull head 18 comes upper end, the upper end of distance pull head 18, chain tooth 14c and upper stop member 46 have phase co-altitude and be positioned at the left and right sides, and upper stop member 46 and chain denture 15 merge and integrated.Even if under the state as shown in Figure 2 that pair of right and left chain tooth 14 is opened, upper stop member 46 also seems identical with the chain tooth 14 of chain denture 15, does not have inharmonic sensation, looks comfortable.
It is roughly hemispherical that the cross sectional shape of the thickness direction of the tape member 16 in upper stop member outward appearance portion 54 and the chain tooth outward appearance portion 34 of chain tooth 14 are made like as integrally bending.The upper stop member back 56 of upper stop member 46 is formed as the roughly hemispherical of integrally bending similarly.As shown in Figure 8, the length e (maximum height) from the surperficial 16c of tape member 16 to the highest point in upper stop member outward appearance portion 54 in upper stop member outward appearance portion 54 arranges to obtain △ e longer than the length g of the medial surface 18a of upper flange 20 side from the surperficial 16c of tape member 16 to pull head 18.The length h (maximum height) from the back side 16d of tape member 16 to the highest point at upper stop member back 56 at the upper stop member back 56 of upper stop member 46 arranges to obtain △ f longer than the length h of the medial surface 18b of lower wing plate 22 side from the back side 16d of tape member 16 to pull head 18.In addition, the relation of △ e and △ f meets: △ f > △ e.
Upper stop member 46, be provided with tape member 16 side opposite side side, namely with the chain tooth face in opposite directions of the top in a pair chain denture 15, in the most outstanding part of the side for sphere, be formed with the groove portion 60 parallel with the thickness direction of tape member 16.In the bottom in groove portion 60, the runner trace of the gate portions of mould when there is injection moulding upper stop member 46.Runner trace is the part of the runner eliminating mould, is configured to recess or protuberance 58 relative to the bottom surface in groove portion 60.The degree of depth in the aspect ratio groove portion 60 of the protuberance 58 of runner trace is low and be contained in groove portion 60.By such structure, the possibility being suspended to the skin of people or clothes due to runner trace is low, and runner trace can not damage the skin of people, in addition, runner trace also can be prevented to be suspended to clothes.
Then, the methods of engagement of slide fastener 10 is described based on Fig. 1.For slide fastener 10, at the sidepiece 16a of a pair tape member 16, the mode separating the interval of a chain tooth amount with each chain tooth 14 is separately from each other configured with multiple chain tooth 14, a pair tape member 16 chain tooth 14 offset one from another in opposite directions.For each chain tooth 14, band accepting groove 40 is towards tape member 16 opening of the opposing party, and holding section 42 is positioned at opposition side.And, incline towards each other when being made a pair tape member 16 by pull head 18 and near time, the sidepiece 16a of the tape member 16 of the opposing party is embedded in band accepting groove 40; The holding section 42 of the chain tooth 14 of the tape member 16 of the opposing party is with in opposite directions and the mode of overlap is positioned at holding section 42.Then, after pull head 18 passes through, a pair tape member 16 becomes parallel to each other, and the holding section 42 of chain tooth 14 abuts in parallel with each other, and then becomes engagement.Under engagement, when observing from the surperficial 16c of tape member 16, the chain tooth outward appearance portion 34 of chain tooth 14 has small interval and connects to chain form.Be separated because continuous print chain tooth outward appearance portion 34 has small compartment of terrain each other, and chain tooth outward appearance portion 34 is formed as generally elliptical shape, therefore under the state of slide fastener 10 engagement, no matter make it bending to which direction, adjacent chain tooth outward appearance portion 34 also can not interfere each other, can be freely bending, become the parts that flexibility is high.Because engaging piece 36 and band accepting groove 40 are formed flatly, and engageable head 36b is formed as the generally elliptical shape the same with chain tooth outward appearance portion 34, and therefore it can not be interfered each other, can successfully bend.
For slide fastener 10, under the state that each chain tooth 14 has engaged, the center line of the length direction of the chain denture 15 of tape member 16 side of a side is consistent with the center line of the length direction of the chain denture 15 of tape member 16 side of the opposing party.Namely, when chain tooth outward appearance portion 34 is as in the present embodiment symmetrical shapes, if the chain tooth 14 of slide fastener 10 engages, then because the chain tooth outward appearance portion 34 of the tape member 16 of a side is positioned at same position in the direction of the width with the chain tooth outward appearance portion 34 of the tape member 16 of the opposing party, therefore chain denture 15 is formed as being configured on 1 straight line.Lower stop member 44 is positioned at the continuous print position, bottom with the chain denture 15 be configured on 1 straight line, does not have inharmonic sensation.Upper stop member 46 is positioned at the continuous print position, upper end with the chain denture 15 of a side, does not have inharmonic sensation.When opening slide fastener 10 making pull head 18 slide downwards, in the bottom of chain denture 15, the lower wing plate 22 of pull head 18 abuts with the lower stop member back 50 of lower stop member 44 and stops, thus can not come off.If pull head 18 applies power downwards after abutting with lower stop member back 50 further, the lower stop member back 50 of stop member 44 is then descended to be pressed and to rotate centered by the annex of tape member 16, thus lower stop member outward appearance portion 48 rolls tiltedly to pull head 18 and abuts with pull head 18, the upper flange 20 of pull head 18 also abuts with the lower stop member outward appearance portion 48 of lower stop member 44, and then reliably stops.
In addition, for slide fastener 10, under the state that each chain tooth 14 has engaged, pull head 18 is positioned near upper end, although uppermost chain tooth 14c can be seen from pull head 18, with the position of this chain tooth 14c symmetry on can see upper stop member 46, thus there is no inharmonic sensation.When making pull head 18 slide upward, in the upper end of chain denture 15, the lower wing plate 22 of pull head 18 abuts with the upper stop member back 56 of upper stop member 46 and stops, thus can not come off.If pull head 18 applies power after abutting with upper stop member back 56 further upward, then the upper stop member back 56 of upper stop member 46 is pressed and rotates centered by the annex of tape member 16, the upper flange 20 of pull head 18 abuts with the upper stop member outward appearance portion 54 of upper stop member 46, and then reliably stops.
Slide fastener 10 according to the present embodiment, lower stop member 44 and upper stop member 46 are installed on the end of chain denture 15 respectively, lower stop member 44 and upper stop member 46 stop the slip of pull head 18, stably can prevent pull head 18 from coming off from slide fastener 10, reliably can maintain the engagement of chain tooth 14.Lower stop member 44 and upper stop member 46 have design, and owing to being ball shape, do not have sharp keen part, even if also can not produce pain with skin contact.And lower stop member 44 and upper stop member 46 are in tape member 16 directly injection moulding, can install it with high intensity simply and reliably.
For lower stop member 44 and upper stop member 46, its lower stop member outward appearance portion 48, upper stop member outward appearance portion 54 are arranged to the shape similar to the chain tooth outward appearance portion 34 of chain tooth 14, look as chain tooth 14 when being arranged in chain denture 15, so there is no inharmonic sensation, outward appearance becomes good.Due to lower stop member 44 and upper stop member 46 from the lower stop member back 50 that the surperficial 16c of tape member 16 can't see, upper stop member back 56 in the length of the thickness direction of tape member 16 than the length of the engaging piece 36 of chain tooth 14, therefore can reliably abut with pull head 18, but under the state of observing from the surperficial 16c of tape member 16, lower stop member 44 and upper stop member 46 look identical with chain tooth 14, lower stop member 44 and upper stop member 46 are shapes slightly higher than chain tooth 14, do not have inharmonic sensation.And lower stop member 44 is positioned at when a pair chain denture 15 engages and arranges on the extended line that configures in a row with chain form, lower stop member 44 merges with chain denture 15 and integrated, applies flexibly the external appearance characteristic of chain denture 15, can have high aesthetic appearance.When pair of right and left chain tooth 14 engages, when pull head 18 comes upper end, the upper end of distance pull head 18, upper stop member 46 and chain tooth 14c are positioned at phase co-altitude, upper stop member 46 and chain denture 15 merge and integrated, upper stop member 46 seems identical with the chain tooth 14 of chain denture 15, does not have inharmonic sensation, looks comfortable.
In addition, for the slide fastener 10 of present embodiment, although lower stop member back 50, the upper stop member back 56 of pull head 18 and lower stop member 44 and upper stop member 46 abut and stop, but once apply brute force further in the direction of advance of pull head 18, lower stop member 44 and upper stop member 46 can tilt, thus lower stop member outward appearance portion 48, upper stop member outward appearance portion 54 abut with pull head 18 and then reliably can stop the slip of pull head 18.
