So that：When recess 50a, 50b formation with first direction B and second direction C vertical axis (in the foregoing manner) on bending
Slide fastener a part when, the friction between the pull head 11a and chain belt of the slide fastener of the bending section office of slide fastener is reduced.This leads to
Cross following manner realization.
Fig. 5 is looked back it can be seen that for the known pull head 11 of the bent portion by slide fastener 10, the head end of pull head 11
The connecting portion 14c for the tooth chain belt being forced at the 48b of position with chain belt 18 is in contact by the bottom 32 at 38.When pull head 11a
When the bent portion of slide fastener, recess 50a and 50b enable slide fastener 10 tooth chain belt connecting portion 14c with the head end 38a of pull head
The mode that contact between the engaging piece of the chain belt at place and pull head 11a reduces (and eliminating in some cases) passes through pull head
11a.This causes the friction being provided with the bending section office of slide fastener between pull head 11a chain belt and pull head 11a to reduce.Knot
Really, by the way that any of above caused by the friction between pull head and chain belt potential ask has been reduced or eliminated according to the pull head of the present invention
The generation of topic.
Each in the pair of recess 50a, 50b is substantially concave recess.Recess 50a, 50b are respectively formed at
Bottom 32a left side and right side.Concave recess refers to that the center of curvature of the recessed portion of circumference 48 is located at the outside of circumference 48
(opposite with circumference 48).As a result, recess 50a, 50b are attributed to, the sizes of bottom 32a in left-right direction are from pull head along preceding
Rear to pars intermedia be gradually reduced to the head end of pull head.In other embodiments, recess can have arbitrarily suitable shape
Shape.For example, recess can be (that is, being limited by substantially linear) of convex, polygon or oblique line.
It is probably favourable in a particular application as the recess of re-entrant recess.This is described in more detail later.
Fig. 9 a show the pull head 11a for the part to form slide fastener 10a.In this embodiment, slide fastener 10a includes single draw
Head 11a.
Fig. 9 b show a kind of slide fastener 10b, and it includes two pull heads (each pull head is denoted as 11a in the figure).With when drawing
The end surface of one pull head configures two pull heads to the mode of the head end of another pull head when head 11a is adjacent to each other.This refers to
One pull head 11a carries out engagement/disengagement engaging piece in the direction of motion opposite with the direction of motion of another pull head.
In the application for needing fixed fastening, the drawing shown in Fig. 9 b that two pull heads can be pulled together can be used
Chain, thus closed zipper and then fix.Pull head 11a in Fig. 9 b is shown with this construction.Pull head can be by solid each other
Determine or be fixed on a position so that slide fastener is remained closed.
Even if when pull head 11a is positioned along slide fastener in a contact fashion, however it remains the part 52 between pull head 11a,
It is not engaged with each other in the engaging piece of the part tooth chain belt.
Slide fastener 10b this non-engaging portion is undesirable for some reason.First, if non-engaging portion is special
Greatly, and if non-engaging portion is not covered by pull head 11a, then device may can be inserted in non-engaging portion and compeled
Open slide fastener.Secondly, non-engaging portion causes pull head 11a relative to some transverse movements of slide fastener remainder.Pull head phase
Transverse movement for the remainder of slide fastener can also cause the chain tooth of slide fastener to be threaded off, therefore slide fastener is opened.
Due to above mentioned problem, applicants have determined that, at least one in the upper and lower part of the head end of pull head
For side advantageously have general planar part, the flat with second direction C generally perpendicular directions and
Extend in the plane of appropriate section.In other words, the general planar part of the top of pull head or bottom can be with defined below.It can lead to
