Description
Technical Field
The present utility model relates to a slide fastener, and more particularly, to a light slide fastener which is a kind of connection member on a fabric, and which can be selectively applied to connect two separate fabrics and allow them to slide relatively.
Background
Slide fasteners are common in everyday life and generally comprise an axially extending left zipper strip, a right zipper strip and an axially sliding slider by means of which sliding the elements on the left and right zipper strips can be mutually engaged or disengaged. The existing fastener elements are generally integrally formed rigid structures, such as cold extrusion formed metal fastener elements or injection molded resin fastener elements, and the left fastener elements of the left fastener tape and the right fastener elements of the right fastener tape are all extruded by the pull head to be matched with each other in a concave-convex manner to be meshed together in the process of pulling and combining the left fastener tape and the right fastener tape. The left element and the right element require relatively large pressing forces to be able to mesh together due to the influence of the associated dimensional accuracy of fit. And the pull head can generate certain friction force with the zipper teeth or the cloth belt in the sliding process. The existence of the above factors can influence the closing smoothness of the zipper, and the hand feeling and the releasing speed of the zipper when the slider on the zipper is pulled are influenced to a certain extent. In order to improve the light sliding property of the slide fastener, various solutions have been proposed, such as an elastically engaged slide fastener in chinese patent No. CN201410348920.2, which is an improvement in terms of element structure, a hook-shaped dislocation tooth injection-molded slide fastener in chinese patent No. CN200410030762.2, or a slider, which is an improvement in terms of slider structure, in chinese patent No. CN201620244875.0, which reduces friction with the element, and so on. However, in many of the above solutions, the problem that the sliding property is affected by the resistance generated by the mutual extrusion between the fastener element and the slider cannot be solved well.
In chinese patent No. CN201410658506.1, a safety slide chain is proposed, which includes a top chain body and a bottom chain body, and can solve the above problems well. The upper chain body comprises a plurality of clamping rings arranged on the base cloth, the clamping rings comprise two arc-shaped clamping arms which are connected into a whole, and the end parts of the clamping arms are spherical. The lower chain body comprises a strip-shaped chute and a base cloth connecting seat arranged at the lower end of the chute, the chute is an inverted trapezoid chute, protruding ribs are arranged on four edges of the chute, protruding ribs at the top end of the chute extend out of the outer end of the chute and are provided with limiting tables, the protruding height of each protruding rib at the top end of the chute is larger than that of protruding ribs at the other three edges, the base cloth connecting seat is connected with the base cloth, and the upper chain body is clamped on the protruding ribs of the chute through clamping rings so as to be connected with the lower chain body. The proposal in the Chinese patent 201410658506.1 completely omits the setting of the pull head, thereby completely avoiding the extrusion friction of the pull head to the sprocket. However, the slide chain is very prone to jamming between the grip ring and the slide groove in use, for example, as shown in fig. 1, when the slide fastener 100 is used for engagement between the coat neck 41 and the coat neck 4, the coat neck 41 is positioned at the neck position and the coat neck 4 is worn on the head, and the elevation of the head is different from the elevation of the neck. In one use, the cap 4 at the head will form a pulling force on the collar 41 in an oblique direction such that the runner will abut against the grip ring to form a significant frictional resistance, thereby affecting the smooth sliding of the zipper.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides an asymmetric light slide fastener which comprises a first chain belt and a second chain belt which are arranged left and right and respectively extend axially, wherein female teeth which are arranged at intervals along the axial direction are arranged on the inner side of the first chain belt, the female teeth comprise female tooth heads and female tooth tails which are arranged left and right, the female tooth tails are connected with the first chain belt, the female tooth heads extend out from the female tooth tails to form an open ring shape so as to be provided with female tooth grooves and female tooth notches, and female tooth grooves of the female teeth which are arranged front and back at intervals are combined into an axially extending storage groove channel; a male fastener element head extending in an axial direction and capable of being accommodated in the female fastener element groove is provided on an inner side of the second fastener tape, the height of the male fastener element head being greater than the height of the female fastener element notch and less than the height of the female fastener element groove, the male fastener element head being capable of sliding axially in the receiving groove passage when the male fastener element head is inserted into the female fastener element groove; the female tooth head is characterized in that the horizontal center line of the female tooth socket of the female tooth head is staggered relative to the horizontal center line of the female tooth tail when seen from the cross section.
Wherein the axial direction is a length extending direction (a direction of the Y axis in fig. 2) of the first and second links. And the left and right are directions perpendicular to the axial direction, that is, transverse (the direction of the X-axis in fig. 2).
Wherein, the height of the male element head is greater than the height of the female element notch and less than the height of the female element notch. Thus, a certain movable gap is formed between the male fastener element head and the female fastener element groove, friction force between the male fastener element head and the groove wall of the female fastener element groove is reduced, the male fastener element head can slide into the adjacent female fastener element groove from one female fastener element groove easily, but the male fastener element head inserted into the female fastener element groove cannot move transversely to pass through the female fastener element groove opening and be separated from the female fastener element groove.
Wherein the horizontal center line is a horizontal reference line passing through a midpoint in the up-down direction when viewed in cross section, so that the horizontal center line is a reference line extending in the horizontal direction at first and is located at a midpoint in the up-down direction. For example, the horizontal center line of the female socket of the female head portion refers to a reference line which is located at a midpoint position of the female socket in the up-down direction and extends in the horizontal direction. Unless otherwise specified, the horizontal centerlines discussed below are defined identically. The horizontal center line of the female socket of the female head part is offset with respect to the horizontal center line of the female tail part, i.e. the female socket of the female head part is offset with respect to the female tail part, seen in cross section. The direction in which the horizontal center line of the female fastener element groove and the horizontal center line of the female fastener element tail are observed is defined in a cross-sectional view, and the direction in which the section obtained by axially observing the female fastener element is transversely cut perpendicular to the tape surface of the first fastener tape is actually the cut direction shown by the A-A cut line in fig. 2, or the direction in which fig. 3 is observed is defined in a cross-sectional view.
According to the technical scheme, compared with the prior art, the utility model has the beneficial technical effects that: since the horizontal center line of the female socket of the female head part is offset with respect to the horizontal center line of the female tail part as seen in cross section. Such that when the male element head is inserted into the female element groove, the first and second links are disposed on different vertical surfaces, for example, vertical surfaces which are spaced apart from each other up and down and are substantially parallel to each other, and the first and second links may be adapted to be connected to fabrics located on the different vertical surfaces. The female fastener element notch can provide an offset avoidance space for the second chain belt or the male fastener element tail which is arranged on the second chain belt and connected with the male fastener element head, so that the second chain belt or the male fastener element tail sliding under the traction of fabric can be reduced or avoided, and obvious friction resistance is formed due to the fact that the second chain belt or the male fastener element tail is abutted against the notch wall of the female fastener element notch. Unlike the safety slide chain proposed in chinese patent No. CN201410658506.1, the asymmetric light slide fastener of the present utility model can be better adapted to connect to braids located on different elevations and maintain good smoothness.
Further technical scheme may be that, seen from the cross section, the center line of the female element notch of the female element has an included angle with the horizontal center line of the female element slot. Wherein the female element notch center line means a line connecting a midpoint of the female element notch in the opening width direction thereof and a groove center point of the female element groove in a cross-sectional view. In this way, when the male element head is inserted into the female element groove, an included angle is formed between the first chain belt and the second chain belt, and the first chain belt and the second chain belt are arranged in a relatively inclined manner. And the female tooth notch of the female tooth provides an avoidance space for inclined sliding for the second chain belt or the male tooth tail which is arranged on the second chain belt and connected with the male tooth head, thereby being beneficial to reducing or avoiding the second chain belt or the male tooth tail sliding under the traction of fabric from leaning against the notch wall of the female tooth notch to form obvious friction resistance. The zipper may be adapted to connect fabrics arranged in a relatively oblique manner.
In order to optimize the appearance effect of the female fastener element, the female fastener element may further adopt a technical scheme that the overall thickness of the female fastener element head is greater than that of the female fastener element tail, and the horizontal center line of the female fastener element head is offset from the horizontal center line of the female fastener element tail in the cross section. Thus, the female tooth tail is offset to one of the upper side or the lower side of the female tooth head, so that the female tooth has a flexible and active appearance effect.
Further, the upper side surface of the female element is basically straight, and the lower side surface of the female element is in an uneven appearance. Wherein the upper side of the female element is substantially straight relative to its lower side, the upper side of the female element being generally flatter than the lower side, but it is not excluded that there is a relatively slight difference in height between a partial face area on the upper side and other face areas thereon. The upper side of the female element is not necessarily a plane, but may further be a polygonal plane or a spherical plane. The lower side surface of the female element has an uneven outer shape, and is also opposite to the upper side surface of the female element. In contrast to the upper side of the female element, the lower side of the female element has at least two surface areas with a relatively pronounced height difference, for example, the lower side of the female element is further stepped.
The further technical scheme may be that the upper side face of the female fastener element is a polygonal face, and the lower side face is a stepped face. Or, the upper side surface of the female fastener element is a spherical surface, and the lower side surface is a stepped surface.
As for the male element heads, various structural forms can be adopted, and further technical solutions may be that the male element heads are arranged at intervals along the axial direction inside the second chain belt. In this way, the male element heads are arranged at intervals from each other like the beads in a necklace, and are connected together in series by the second chain belt. In this way, the second chain belt has relatively excellent flexibility without being excessively rigid. When applied to an article and when wrinkles appear in the fabric of the article, adjacent male element heads can adapt to the deformation of the fabric of the article, and the positions of the male element heads can be adjusted automatically, so that the axial sliding of the male element heads in the female element grooves of the female element is facilitated.
Or the male element head may further adopt a technical scheme that the male element head extends continuously along the axial direction at the inner side of the second chain belt. Thus, the male element head is in a long string shape.
The utility model also provides a product applying the light slide fastener, wherein a first fabric edge and a second fabric edge are reserved on the product, a first chain belt of the light slide fastener is sewn on the first fabric edge, and a second chain belt is sewn on the second fabric edge.
Since the present utility model has the above-described features and advantages, it can be applied to a light slide fastener and an article to which the same is applied.

Thus, the female dental tail 33 is biased to one of the upper side and the lower side of the female dental head 34, and in the present embodiment, the female dental tail 33 is biased to the upper side of the female dental head 34. Seen from the cross section, the female element 3 has a cross section structure with upper and lower asymmetry, and the appearance contour is flexible and active.
As shown in fig. 2, 3 and 4, the upper side 31 of the female element 3 is substantially flat and the lower side 32 has an uneven profile. Wherein the upper side 31 of the female element 3 is substantially straight relative to its lower side 32, the upper side 31 of the female element 3 as a whole being flatter than the lower side 32, but it is not excluded that there is a relatively slight difference in height between a partial area on the upper side 31 and other areas thereon. The upper side 31 of the female element 3 is not necessarily planar. In the present embodiment, the upper side 31 is a polygonal surface, or as shown in fig. 6 and 7, the female element 3b according to the third embodiment is employed, and the upper side 31b is a spherical surface. The lower surface 32 of the female element 3 has an uneven outer shape, and the lower surface 32 of the female element 3 has at least two surface areas having a relatively significant height difference with respect to the upper surface 31 of the female element 3, and in the present embodiment, the lower surface 32 of the female element 3 is a stepped surface.
