Two of such upside flanges 44,44 and upper flange 41 is utilized to form the top of slider body 4.That is, the top of slider body 4 does not comprise and links post 43.And as shown in Figure 6, the maximum gauge size t of above-below direction is on the top of slider body 4, diameter 5d (such as 0.9mm) the < t < 2.5mm of bolster 5.Preferably t < 2.3mm.By the way, in the present embodiment, about the upper surface of upper flange 41, its fore-and-aft direction pars intermedia and rear portion are horizontal plane and are the highest position, and the lower surface of two flanges 44,44 of upside is mutually level horizontal plane and is minimum position.Therefore, in the present embodiment, the fore-and-aft direction pars intermedia from left and right end portions of slider body 4 is the part of the maximum gauge size t with above-below direction to rear portion.Thus, the maximum gauge size t of above-below direction refers to the size of the above-below direction between the lower surface of the upper surface of upper flange 41 and the pair of flanges 44,44 of upside.
As shown in Figure 7, Figure 8, chain tooth path 45 be utilize upper flange 41, lower wing plate 42 by up and down and outside separate, utilize 4 flanges 44,44 ... the space formed in left and right and outside separating is the space run through along the longitudinal direction.In addition, the linearly extension in rear portion of chain tooth path 45, the rear end of chain tooth path 45 becomes the deutostoma 45b supplying a pair chain denture 22,22 of engagement to pass through.On the other hand, the front portion of chain tooth path 45 utilizes link post 43 to branch into two in left and right toward the front, and the front end of chain tooth path 45 becomes a pair prosopyle 45a, 45a supplying a pair chain denture 22,22 of released state to pass through.That is, chain tooth path 45 entirety is Y shape.When a pair chain dental strip 2,2 is open mode, that is, when making pull head 3 rearward move, a pair chain denture 22,22 of engagement is imported in chain tooth path 45 by from deutostoma 45b together with a pair zipper strip 21,21 being located thereon side.Then, a pair chain denture 22,22 is divided right and left by link post 43, and a pair chain denture 22,22 of released state is discharged by from prosopyle 45a together with a pair zipper strip 21,21.On the other hand, when a pair chain dental strip 2,2 is closure state, that is, when making pull head 3 forwards move, a pair chain denture 22,22 of released state is imported in chain tooth path 45 by from prosopyle 45a together with a pair zipper strip 21,21.Then, linking the rear side of post 43, a pair chain denture 22,22 engages, and a pair chain denture 22,22 of engagement is sent by from deutostoma 45b.
Each slide fastener trough of belt 46 is formed at the space between upper lower flange 44,44 respect to one another.Left and right slide fastener trough of belt 46,46 is connected with the left and right of chain tooth path 45.In addition, the outstanding outstanding length being upward shorter in length than lower side flange 44 downwards of upper flange 44, therefore each slide fastener trough of belt 46 is formed as being partial to the state be communicated with on the upside of chain tooth path 45.
Pulling-on piece 6 comprises for pointing the pulling-on piece main body 61 gripped and a pair arm 62,62 extended from the left and right sides of pulling-on piece main body 61.Each arm 62, in bar-shaped, is formed with the ring 62a passed through for bolster 5 in its top ends.And the through in left-right direction and rounded shape in the hole being formed at the inner circumferential side of ring 62a, the radius in hole is formed less times greater than the radius of bolster 5 as shown in Figure 4.In addition, the periphery of ring 62a is also toroidal, and in more detail, because arm 62 is the shapes in bar-shaped extension, therefore the periphery of ring 62a is C-shaped.The peripheral radius of ring 62a is identical to the distance of the above-below direction of upper flange 44 lower end with the center from bolster 5.Due to the peripheral radius of the hole dimension and ring 62a that form ring 62a in the manner described above, therefore, be installed on the roughly the same with the lower end of the flange 44 of upside bottom of the periphery of the ring 62a of bolster 5.On the other hand, as shown in Figure 5, under the state that left and right arms 62,62 is kept level, the top of the periphery of ring 62a is than the upper surface of slider body 4 and the upwardly projecting preliminary dimension 62t of the upper surface of upper flange 41.Thus, the upper surface of slider body 4 is formed lower than the upper surface of the ring 62a of left and right arms 62,62.In addition, pulling-on piece main body 61 is frame-shaped.
In the pull head 3 of first embodiment of the invention described above, maximum gauge size t due to the above-below direction by slider body 4 top is set to diameter 5d (such as 0.9mm) the < t < 2.5mm of bolster 5, therefore, it is possible to reduce fully relative to a pair zipper strip 21,21 upwardly projecting outstanding length, and then overhang can be reduced fully.
In addition, about the top of the slider body 4 of pull head 3, formed the thickest by the thickness of the above-below direction by its left and right end portions at fore-and-aft direction pars intermedia, the part making bolster 5 be formed the thickest from this is outstanding to side, thus can guarantee the intensity (thickness) as bolster 5.On this basis, about the top of the slider body 4 of pull head 3, its upper surface is set to from front end towards the acclivitous ramp 41s of fore-and-aft direction pars intermedia, and the leading section of its lower surface is also set to lower inclined plane 41u, therefore, it is possible to reduce fully relative to a pair zipper strip 21,21 upwardly projecting overhangs.
And, pull head 3 owing to the upper surface of slider body 4 being formed the upper surface of ring 62a of a pair arm 62,62 that keeps than level is low, therefore, it is possible to reduce relative to a pair zipper strip 21,21 upwardly projecting overhangs.
In addition, slider body 4 is formed as along with going towards front 41a from fore-and-aft direction pars intermedia and is close to left and right directions pars intermedia gradually due to left and right side 41c, the 41d on its top, therefore, the left and right width dimensions of the fore-and-aft direction pars intermedia of slider body 4 can adopt a pair chain denture 22,22 by required minimum dimension, and the top that can reduce slider body 4 is relative to a pair zipper strip 21,21 upwardly projecting amounts.
Like this, for the pull head 3 of the first embodiment, owing to can reduce relative to a pair zipper strip 21,21 upwardly projecting overhangs, therefore, it is possible to bring impression thinner on the whole.
As shown in Figure 10, apply the pull head 3 of two first embodiment of the invention, the slide fastener 1 of second embodiment of the invention, be installed on a pair chain dental strip 2,2 to make the relative state in the front end of two pull heads 3,3.Between the front and back of two pull heads 3,3 and between a pair chain dental strip 2,2, (in more detail, between a pair chain denture 22,22) is formed with gap 2a.
If make two pull heads 3,3 be close, then gap 2a narrows.And if make two pull heads 3,3 abut against, then gap 2a disappears, and as shown in figure 11, the front end face of pull head 3 contacts, thus the sealing under a pair chain dental strip 2,2 closure state improves.And because the front 41a of the upper flange 41 of each pull head 3,3 is linearities parallel with left and right directions, and the front end face comprising front 41a is the vertical guide parallel with above-below direction, be therefore easy to maintain the state that the front end face of pull head 3 is against each other.
By the way, if make two pull heads 3,3 be close, then as shown in Figure 10, the part being positioned at two pull heads 3,3 left and right sides of a pair zipper strip 21,21 is (hereinafter referred to as " the neighbouring part of pull head ".) with the mode heaved laterally be arc-shaped distortion.This distortion occurs significantly when two pull heads 3,3 abut against as shown in figure 11.And user makes pull head 3 move in the mode mentioning pulling-on piece 6 slightly to upside usually, the neighbouring part of the pull head therefore in a pair zipper strip 21,21 becomes swells such shape slightly to top.And in slide fastener 1, the side contrary with side edge part toward each other of a pair zipper strip 21,21 is fixed in the objects such as clothes, becomes near the pull head therefore in a pair zipper strip 21,21 and swell such shape further upward.Allow that the shape of this protuberance is one of intended shape of two pull heads 3,3.If each pull head 3 hinders this protuberance, then two pull heads 3,3 cannot maintain abutting state and separate front and back, thus cannot guarantee sealing.But, due to left and right side 41c, the 41d on pull head 3 top are formed as being close to left and right directions pars intermedia along with from fore-and-aft direction pars intermedia gradually towards front 41a, therefore, compared with situation in the linearity parallel with fore-and-aft direction of left and right side 41c, 41d of such as a pair pull head 3, the neighbouring part of the pull head in a pair zipper strip 21,21 is allowed to swell upward.And, in each pull head 3, edge part due to the front portion of the lower surface of upper flange 41 is set as lower inclined plane 41u, 41u, 41v, 41v, therefore with such as the lower surface of upper flange 41 is set to simple horizontal plane pull head situation compared with, the neighbouring part of the pull head in a pair zipper strip 21,21 is allowed to swell upward.
First variation of the pull head 3 of first embodiment of the invention as shown in Figure 12 and Figure 13, the upper surface of upper flange 41 is pasted ornamental sheet material 7, and this point is different from the pull head 3 of the first embodiment.
Sheet material 7 is applied with at upper surface expects that color printing word, figure, symbol etc. form.
The present invention is not limited to above-mentioned embodiment, can suitably change in the scope not departing from its purport.Such as, the maximum gauge size t of the above-below direction on slider body 4 top has been set to t < 2.5mm by the pull head 3 of present embodiment, but be not limited to this, also t >=2.5mm can be set to, in this case, the upper surface of slider body 4 is formed lower than the upper surface of a pair ring 62a, 62a of a pair arm 62,62 of level maintenance.
In addition, the front 41a of the pull head 3 of present embodiment in the linearity parallel with left and right directions, but is not limited to this, also can be other shapes such as the shape heaved in arc-shaped.
And, in the left and right end portions of the slider body 4 of present embodiment, on top and bottom, all there is flange 44, but be not limited to this, also can be only in the left and right end portions of slider body 4 bottom, there is flange 44, and there is no flange 44 in the left and right end portions on slider body 4 top.
In addition, the shape of the upper flange 41 of the pull head 3 of present embodiment is different from the shape of lower wing plate 42, but is not limited to this, and the shape of upper flange 41 also can be made consistent with the shape of lower wing plate 42.
