The specific embodiment
Referring to Fig. 2 and Fig. 3, a kind of curve slide fastener comprises sprocket 1 and the slider of zipper fastener 2 that mates with sprocket 1, and sprocket 1 comprises some sprockets 11 and following sprockets 12 gone up, some sprocket 11 and following sprocket 12 mutually nested fixed formation whole chain teeth 1 gone up, last sprocket 11 and following sprocket 12 are two sprockets diversified in specifications; With sprocket 1 top for being as the criterion down, last sprocket 11 be wide at the top and narrow at the bottom, down sprocket 12 for up-narrow and down-wide or down sprocket 12 be wide at the top and narrow at the bottom, upward sprocket 11 is up-narrow and down-wide; Also correspondingly lack a length of side, diversified in specifications on one side with the slider of zipper fastener 2 of sprocket 1 coupling; Some sprockets 11 of going up are that the mutual left and right sides is nested fixed or nested fixed up and down mutually with following sprocket 12; Sprocket 1 and can be metallic bond tooth, metal zip fastener head or plastics sprocket, plastic fastener head with the slider of zipper fastener 2 of sprocket 1 coupling.
Wherein a kind of structure is: some upward sprockets 11 are that the mutual left and right sides is nested fixed with following sprocket 12, its top is equipped with convex edge 110 and groove 111 from outside to inside, it is mutually nested fixed with the convex edge 110 of following sprocket 12 with the groove 111 of the groove 111 of following sprocket 12, last sprocket 11 wherein to go up the convex edge 110 of sprocket 11, referring to Fig. 2.
Another kind of structure is: some sprockets 11 of going up are nested fixed up and down mutually with following sprocket 12, its top is provided with flange 210 or embeded slot 212 from outside to inside, the flange 210 of wherein going up sprocket 11 and the embeded slot 212 of following sprocket 12 or to go up the embeded slot 212 of sprocket 11 mutually nested fixed with the flange 210 of following sprocket 12 are referring to Fig. 3.
The utility model operation principle is:
When slide fastener when curvilinear path is worked, its curve can form corresponding radian.And be positioned at sprocket 1 on the curve chain cloth, can constitute one is the string of sprocket 1 facewidth, in the pairing angle of this string, make the required a pair of sprocket 1 of chain cloth up and down, (be two sprockets diversified in specifications: cochain cloth sprocket is wide at the top and narrow at the bottom, following chain cloth sprocket is up-narrow and down-wide, with the chain tooth tip under be as the criterion.) again because convex edge 110/ flange 210 has been rushed examination at sprocket 1 top on one side, dig on one side and be provided with groove 111/ embeded slot 212, so convex edge 110/ flange 210 can be nested fixed in groove 111/ embeded slot 212 at the inboard adjacent sprocket of another slide fastener selvedge 1 top when 2 reinforcings of special slider of zipper fastener, because of shape difference makes its sprocket complementary space up and down, mutually nested, form a perfect curve slide fastener.
Determine the method (as shown in Figure 4) of sprocket tooth body size up and down.
1. according to required slide fastener radian and slide fastener arc length, make camber line 0. with radius R
2. deduct the radius R 2 that sprocket tooth height degree 11 backs form with radius R, make camber line 3
3. add the radius R 1 that sprocket embeded slot height 22 forms with radius R 2 again, make camber line 2;
4. deduct the radius R 3 that sprocket tooth height degree 11 forms with radius R 1 again, make camber line 4.
5. at the string 6 of making the facewidth on the cochain cloth sprocket on the camber line 0, and connect the center of circle and sit out isosceles triangle.
6. according to the triangle theorem: parallel and leg-of-mutton one side, and and the straight line that intersects of other both sides, the Atria limit correspondence that is intercepted is proportional.Therefore, can be according to known radius R, R1, R2, R3, and tooth facewidth string 6 on the cochain cloth sprocket, obtain respectively be positioned at camber line 2,3,4, on equal the string 7,8,9 of the facewidth.
Ask the string formula: R/R2=string 6/ string 8
R1/R2=string 7/ string 8
R1/R3=string 7/ string 9
Promptly to make width while being string 6, being the tooth body of the upper curve chain cloth sprocket 21 of string 8; While being string 9, being the tooth body of the lower curve chain cloth sprocket 31 of string 7, determined the size of sprocket tooth body with this, make slide fastener according to the method for sprocket Zhi Gan, groove, the protruding wing about making again and get final product.
Concrete method of work is:
With the sprocket up and down of gained, be placed in respectively on the lower curve chain cloth after staying spacing, form slide fastener as shown in Figure 3, its method of work is in conjunction with Fig. 3 and Fig. 5.
Nested about in the of 1 with sprocket is that example is described:
The flange 210 at last sprocket 11 tops of upper curve chain cloth is under the situation of slider of zipper fastener 2 reinforcings, and to dig the embeded slot of establishing 212 nested fixed with adjacent down sprocket 12 tops of lower curve zipper cloth inboard.Just because of be such design, thus can make the flange 210 of the last sprocket 11 that disagreement closes and following sprocket 12 embeded slot 212 complementary space, mutually nested, form a perfect curve slide fastener.
