Lower stopper of zipper

Technical Field

The utility model relates to a zip fastener technical field especially relates to a lower end utensil of zip fastener.

Background

The zipper is divided into an open zipper and a closed zipper according to the type of opening and closing of the lower end thereof. The open zipper is generally arranged on the clothes, the open zipper is a zipper formed by combining two independent single-side tooth chains and a plug rod, a socket and a pull head, and the plug rod and the socket at the bottom end of the two single-side tooth chains can be separated. The closed zipper is generally commonly used at the front fly of trousers or skirt, the closed zipper is a zipper formed by combining two single-side tooth chains together at the bottom ends through a lower stop part, the bottom ends of the two single-side tooth chains cannot be randomly separated, and the zipper is generally commonly used at the front fly of trousers or skirt.

In general, since the closed end of the closed end fastener is closed, the closed end fastener cannot be separated freely, and when sewing the closed end fastener to an article, it is necessary to assemble the tape with the fastener elements and the slider of the fastener first, and it is necessary to slide the slider during sewing, thereby avoiding the obstacle caused by the slider. This makes the sewing position of the article to which the closed slide fastener is attached restricted and difficult to adjust.

An improved structure also appears for the closed zipper, and the bottom end stop of the existing closed zipper comprises a pull head and two single-side tooth chains; the slider includes: a rear wing panel; a guide post vertically disposed on the rear wing plate; a front wing plate extending downward from the guide post; two left and right guide flange portions, each of which is connected to the rear wing plate and each of which is connected to the front wing plate; in the direction from bottom to top, the two guide flange portions transition from a position close to each other to a position away from each other; the rear wing plate, the guide post, the front wing plate, and the two guide flange portions form a Y-shaped element guide path for guiding the element portions of the two single-sided fastener elements to pass through;

the bottom end stop has a two-part structure including a first member and a second member disposed opposite to each other, the first member and the second member being respectively disposed on two single-sided fastener stringers, and at least two pairs of hook-shaped coupling heads and coupling recesses being respectively formed on opposite surfaces of the first member and the second member. And at least two pairs of the hook coupling heads and the coupling recesses are sequentially disposed along the length direction of the slide fastener in order to enable the first member and the second member to be stably coupled. The single-sided fastener stringers corresponding to the first and second members of the bottom end stop of the closed-end slide fastener may be sewn separately to the article, and then the first and second members are attached together with the slider.

However, since the Y-shaped element guide path includes a bottom opening between lower portions of the two guide flange portions and two shoulder openings connecting upper ends of the bottom opening, each of the shoulder openings is between a guide post and an upper portion of the corresponding guide flange portion, i.e., the upper portions of the two guide flange portions are extended outwardly; therefore, when the slider moves from the bottom to the top, the first member and the second member press and rub the slider, and the movement of the slider is hindered. In the prior art, the friction side surfaces of the first member and the second member and the slider are basically straight and very hard, so that the bottom end stop cannot be greatly inclined outwards. In actual production, the strength cannot be achieved by manpower and can only be achieved by a machine. In detail, the shape of the side surface of the first member or the second member, which contacts with the slider, is substantially flat, so that in the process of passing the slider through the first member and the second member, in order to make the first member and the second member conform to the structure of the slider, the first member and the second member are required to be in an inverted-V-shaped structure firstly to pass through the corresponding shoulder openings and then enter the bottom opening for combination, which requires a very large force, so that the slider and the bottom end stop can be installed only by adopting machine equipment, and the manufacturing cost is high.

Example 1

As shown in fig. 1 to 11, a lower stop of a slide fastener of the present embodiment, the slide fastener includes a slider 10 and two one-sided fastener stringers 20;

the slider 10 includes:

a rear wing panel 11;

a guide post 12 provided upright on the rear wing plate 11;

a front wing 13 extending downward from the guide post 12;

two guide flange portions 14 provided on the left and right, each of the guide flange portions 14 being connected to the rear wing panel 11, each of the guide flange portions 14 being connected to the front wing panel 13; in the direction from bottom to top, the two guide flange portions 14 transition from a position close to each other to a position away from each other;

the rear blade 11, the guide post 12, the front blade 13, and the two guide flange portions 14 form a Y-shaped element guide path 15 for guiding the element portion 21 of the two one-side element links 20 to pass therethrough; the element guide passage 15 includes a bottom opening 151 and two shoulder openings 152 connecting upper ends of the bottom opening 151, the bottom opening 151 being between lower portions of the two guide flange portions 14, each of the shoulder openings 152 being between a guide post 12 and an upper portion of the corresponding guide flange portion 14;

a lower stop, comprising: the carrying member 100 and the engaging member 200 are oppositely arranged, and the carrying member 100 and the engaging member 200 are respectively arranged on the cloth belts 22 of the two unilateral fastener chains 20;

the receiving member 100 and the engaging member 200 are respectively provided on the tapes 22 of the two one-sided fastener stringers 20;

a hook-shaped joint 210 is arranged on the side surface of the occluding member 200 close to the receiving member 100, and a receiving concave part 110 for inserting the hook-shaped joint 210 is arranged on the side surface of the receiving member 100 close to the occluding member 200;

a notch 220 is arranged on the side of the snap member 200 far away from the receiving member 100, and the notch 220 extends to the bottom of the snap member 200;

when the hook tab 210 is inserted into the receiving recess 110, the lower surface 101 of the receiving member is below the lower surface 201 of the snap member.

From the mounting point of view, before the receiving member 100 and the engaging member 200 are mounted, the receiving member 100 and the engaging member 200 are passed through the shoulder opening 152 of the Y-shaped element guide passage 15 inside the slider 10, and then the slider 10 is moved upward; during installation, the guide post 12 passes through the receiving member 100 and the engaging member 200, the inner side surfaces of the receiving member 100 and the engaging member 200 and the guide post 12 rise after friction, and meanwhile, the receiving member 100 and the engaging member 200 are opened in an inverted V shape in conformity with the structure of the shoulder opening 152 of the Y-shaped element guide path. And after the guide post 12 passes the receiving member 100 and the snap member 200, the receiving member 100 and the snap member 200 are coupled to each other. Finally, after the slider 10 passes through the receiving member 100 and the engaging member 200 and moves above the receiving member 100 and the engaging member 200, the receiving member 100 and the engaging member 200 are completely coupled. In the prior art, after the guide post passes through the first member and the second member of the bottom end stop, the guide flange part of the slider and the side surface of the bottom end stop rub against each other in a large area, and the friction force prevents the slider from moving upwards smoothly and even causes the slider to be stuck with the bottom end stop. Therefore, the surface-to-surface friction between the bottom end stop and the guide flange portion needs to be greatly reduced, so that the excessive friction force generated between the bottom end stop and the slider in the prior art can be reduced, and the slider can be ensured to smoothly pass through the bottom end stop.

When the lower stopper of the zipper of the utility model is installed, the receiving member 100 and the engaging member 200 are respectively inserted into the two shoulder openings 12, the side surface of the engaging member 200 far away from the receiving member 100 is provided with the notch 220, the notch 220 extends to the bottom of the engaging member 200, in the process of pulling the slider 10 upwards, the lower part of the engaging member 200 does not generate surface-to-surface friction with the guide flange part 14 of the slider 10, so that the slider passes through the receiving member and the engaging member, the receiving member 100 and the engaging member 200 can move along the structure of the slider 10, as shown in fig. 5 to 8, the process of combining the receiving member 100 and the engaging member 200 is carried out, the engaging member 200 can be greatly inclined and overturned towards the receiving member 100 in the moving process, the inclined and overturned angle of the engaging member 200 is larger than the included angle formed by the moving direction of the engaging member 200 and the slider 10 before moving, such a structure that the space where the hook joint 210 is combined with the receiving recess 110 is sufficient, that is, the turning space of the receiving member 100 is sufficient, facilitates the insertion of the hook joint 210 into the receiving recess 110, enables the receiving member 100 and the engaging member 200 to be easily engaged together, and prevents poor combination of the receiving member 100 and the engaging member 200. In fig. 5, an angle formed by the engaging member 200 before the movement and the direction in which the slider 10 moves is an angle a between an extension line L3 of a side surface of the engaging member 200 away from the receiving member 100 before the movement of the engaging member 200 and a line L4 indicating the direction in which the slider 10 moves; in fig. 8, the obliquely flipped angle of the engaging member 200 is an angle B between an extension line L3 of a side surface of the engaging member 200 away from the receiving member 100 before the engaging member 200 is moved and an extension line L5 of a side surface of the engaging member 200 away from the receiving member 100 when the engaging member 200 is obliquely flipped to the coupling position.

When the hook-shaped connector 210 is inserted into the receiving recess 110, the lower surface 101 of the receiving member is located below the lower surface 201 of the engaging member, and the lower portion of the engaging member 200 is not caught by the guide flange portion 14 during the process of tilting the engaging member 200 toward the receiving member 100, thereby facilitating the tilting of the engaging member 200. Therefore, the lower stopper of the zipper can be installed by the worker through manual operation, and the success rate of combining the lower stoppers of the zipper is improved.

Since the engaging member 200 is provided with the notch 220, the side surface of the engaging member 200 contacting with the guide flange portion 14 of the slider 10 is in an arc-like structure which is tightened from top to bottom in the length direction of the slider 10, and the arc-like structure corresponds to the element guide path 15 in the slider 10 which is in a Y shape with a wide top and a narrow bottom, so that the engaging member 200 can move in conformity with the structure of the slider 10 during the upward pulling of the slider 10; furthermore, when the notch 220 contacts the guide flange portion 14 during the movement of the engaging member 200, the engaging member 200 can turn leftward with the guide flange portion 14 as a fulcrum and following the shape of the guide flange portion 14; at the same time, the receiving member 100 conforms to the shape of the guide flange portion 14, and is also inclined to the left side, so that the receiving member 100 and the engaging member 200 can be easily engaged together.

In this embodiment, fig. 2 shows a state in which a pair of one-side fastener stringers 20 are joined after the slider 10 is attached to the slide fastener, and the slide fastener is assembled into a closed slide fastener in a state in which the slider 10 is pulled upward at the lower end of the slide fastener. Fig. 9 shows a state in which the pair of one-side fastener stringers 20 are opened after the slider 10 is attached to the slide fastener, and the slider 10 is pulled to the lowermost position and stopped by the lower stopper, and the slide fastener is assembled into a closed slide fastener.

In the present embodiment, each guide flange portion 14 includes a front guide flange 141 and a rear guide flange 142; the front guide flange 141 is connected to the front blade 13, the rear guide flange 142 is connected to the rear blade 11, the front guide flanges 141 of the two guide flange portions 14 extend in a direction approaching each other, and the rear guide flanges 142 of the two guide flange portions 14 extend in a direction approaching each other.

The engaging member 200 is provided with an abutting joint 230, and the receiving member 100 is provided with an abutting groove 130 into which the abutting joint 230 is inserted. The abutment joint 230 is inserted into the abutment groove 130, which can enhance the stability of the coupling of the lower stop of the slide fastener. To facilitate mounting and separating the abutment joint 230 from the abutment recess 130, in this embodiment the head 231 of the abutment joint is planar.

The abutment tab 230 is above the hook tab 210. When the worker pulls the slider 10 upward by mistake, the hook joint 210 is first coupled to the receiving recess 110, and the abutment joint 230 is then coupled to the abutment groove 130, which can facilitate the lower stopper to be coupled quickly and stably. When a worker pulls the slider 10 downwards by mistake to open the lower stopper of the zipper, the upper abutting joint 230 is more easily opened than the lower hook joint 210, so that the force for pulling the slider 10 to move downwards to open the lower stopper can be reduced, the friction force applied to the outer side surfaces of the receiving member 100 and the engaging member 200 is small, and the outer side surfaces of the receiving member 100 and the engaging member 200 are not easily abraded, so that even if the worker pulls the slider 10 downwards by mistake, the receiving member 100 and the engaging member 200 can still be reassembled for use, and the situation that the worker mistakenly pulls the slider 10 to cause large abrasion to the outer side surfaces of the receiving member 100 and the engaging member 200, so that the lower stopper cannot be recovered and can only be discarded can be avoided.

The head end 211 of the hook tab is closer to the tape 22 to which the receiving member 100 is connected than the head end 231 of the abutment tab. This structure makes the engagement of the hook tab 210 with the receiving recess 110 more stable, while making the abutting tab 230 easier to open.

The bottom of the side of the receiving member 100 close to the engaging member 200 is provided with a protrusion 140, and the bottom of the engaging member 200 is provided with a limiting groove 240 into which the protrusion 140 is inserted. The protrusion 140 is formed by extending from the bottom of the side of the receiving member 100 toward the engaging member 200, and this structure makes the bottom of the receiving member 100 and the bottom of the engaging member 200 also form an engaging structure, so that the combination of the lower stopper is more stable.

One-half of the longitudinal length L1 of the snap member 200 is greater than the longitudinal length L2 of the notch 220. This structure allows the length of the region of the snap member 200 where the recess 220 is not provided to be large, so that the overall strength of the snap member 200 is secured. In this embodiment, the ratio of the longitudinal length L2 of the notch 220 to the longitudinal length L1 of the snap member 200 is 9 to 20.

The upper surface 102 of the receiving member 100 is provided with a receiving portion 120 into which the guide post 12 is inserted. After the lower stopper is combined, when a worker pulls the slider 10 downwards by misoperation, the lower end of the guide post 12 is inserted into the accommodating part 120, the contact of the guide post 12 and the upper surface 102 of the receiving member 100 is point contact, the upper end part of the notch 220 of the meshing member 200 and the inside of the slider 10 is point contact, the receiving member 100 and the inside of the slider 10 are surface contact, and two points contact and one surface contact, so that a triangular support structure is formed, when the slider 10 is pulled downwards, the combined lower stopper still has a blocking force and is not easy to open, and the lower stopper can achieve a better stopping effect.

Two hook tabs 210 are provided on the snap member 200 along the front-rear direction of the snap member 200, and the two hook tabs 210 are connected by a first coupling step 310; two abutment joints 230 are provided on the snap member 200 along the front-rear direction of the snap member 200, the two abutment joints 230 being connected by a second coupling step 320; two receiving recesses 110 are provided on the receiving member 100 along the front-rear direction of the receiving member 100, the two receiving recesses 110 being connected by a third coupling step 330; two abutment grooves 130 are provided on the receiving member 100 along the front-rear direction of the receiving member 100, and the two abutment grooves 130 are connected by a fourth coupling step 340.

Because the lower stopping tool of the zipper of the utility model is combined, the worker can complete the combination of the lower stopping tool through manual operation, so the assembly of the lower stopping tool of the zipper of the utility model does not need to adopt machine equipment, which can reduce the installation cost; in addition, in the process of sewing the zipper and the article, the tape 22 with the chain element part 21 can be sewn with the article, and then the chain element part 21 is assembled with the slider 10, so that the problem that the sewing position of the article is limited can be avoided, and in the process of sewing the tape 22 and the article, the slider 10 does not need to be avoided, and the efficiency of sewing the article is improved.

To sum up, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention.
