Description

Auxiliary operation piece and pulling piece for zipper, zipper and article

Technical Field

The utility model relates to an auxiliary operation spare that zip fastener was used.

The utility model discloses still relate to a pulling-on piece that zip fastener was used, and included above-mentioned supplementary operating parts.

The utility model also relates to a zipper comprising the zipper-pulls.

The utility model provides an article that includes above-mentioned zip fastener again.

Background

A zipper is a connecting member for merging or separating articles by means of continuously arranged zipper teeth, and is widely used for articles such as clothes, bags, tents, and the like. As shown in fig. 1, the slide fastener 10 mainly includes a pair of tapes 11 arranged side by side in the left-right direction, a row of fastener elements 12 provided on the inner edge of each tape 11, and a slider 13, wherein the two rows of fastener elements 12 constitute a pair of fastener stringers 14, and the slider 13 is sandwiched between the fastener stringers 14. The slider 13 includes a slider body 131, a pull tab mounting portion 132 fixedly disposed on an upper end surface of the slider body 131, and a pull tab 20 connected to the pull tab mounting portion 132, and when a user holds the pull tab 20 and pulls the slider 13 to move back and forth along an extending direction of the fastener stringer 14, the left and right rows of fastener elements 12 are separated or engaged, thereby opening or closing the slide fastener 10. It can be seen that the amount of pull to move the slider 13 back and forth determines whether the slide fastener 10 can be opened or closed smoothly, and the amount of pull to move the slider 13 back and forth is directly determined by the amount of pull that the user holds and pulls the pull-tab 20 back and forth.

Further, the pull tab in the current slide fastener has several structures as follows.

Structure one, piece formula pulling-on piece: as shown in fig. 2, the pull tab 20 is a thin sheet of metal, typically formed by press-forming, and the pull tab 20 is inserted into the pull tab attachment portion 132 of the slider, and the size of the pull tab 20 matches the size of the slider. However, the sheet tab has the following problems in use:

1. the pull head is pulled to have certain operability, and the use by children is inconvenient.

2. When the zipper is installed on clothes with longer length or luggage with larger size, the zipper has certain length, so that the moving amplitude of the zipper head is larger, the volume of the pull piece 20 is smaller, and when the fingers of a user are far away from the zipper head, the user needs to search the zipper head, thereby reducing the operation convenience.

3. When a user pulls the slider with his/her hand holding the pull-tab 20, the user usually applies a force by pinching one end of the pull-tab 20 away from the pull-tab mounting portion 132 with the tip of the thumb and the tip of the index finger, and the operating areas of the thumb and the tip of the index finger and the pull-tab 20 are small, so that the user cannot apply a large pulling force to the pull-tab 20. When the zipper is a waterproof zipper, the waterproof zipper has higher requirement on air tightness, so that the meshing force of mutual meshing of zipper teeth in the waterproof zipper is larger, and larger pulling force is needed to pull the zipper head, and at the moment, the phenomenon that the waterproof zipper cannot be smoothly opened or closed can exist because a user cannot apply larger pulling force to the zipper pull 20, so that the operation convenience is greatly reduced. The structure of the waterproof zipper is the prior art, and can be referred to a waterproof zipper disclosed in the Chinese patent specification with the publication number of CN 1985695U.

Structure two, ring type pulling-on piece: as shown in fig. 3, the pull-tab 20 is formed in a closed loop shape, and is inserted into the pull-tab attachment portion 132 of the slider, and can be formed by knotting a string such as a pull string, so that the length of the pull-tab 20 can be increased, and the pull-tab 20 can be hooked and pulled by a plurality of fingers, thereby facilitating the user to pull the slider. However, since the pull tab 20 is usually formed by knotting a pull string, the operation area between the user's finger and the pull tab 20 is still small, and the user still cannot exert a large force to pull the pull tab 20, and there is still a phenomenon that the waterproof slide fastener cannot be opened or closed smoothly. In addition, the surface of the pull cord is not smooth, and when a user pulls the pull tab 20, the fingers and the surface of the pull cord rub against each other, so that pain is generated when the force is applied to the pull tab in a large amount, and the use experience is poor. Simultaneously, when the application of force is great, effort can transmit the drawknot department to the stay cord, leads to the stay cord to open easily, the pulling-on piece is inefficacy.

Structure three, ring type injection molding pulling piece: as shown in fig. 4, since the auxiliary operating element 40 is added to the ring-type pull tab, the pull tab 20 includes the coupling member 30 formed of the pull cord and the auxiliary operating element 40, the coupling member 30 is ring-shaped and is inserted into the tab attaching portion 132 of the slider, and the auxiliary operating element 40 is formed by injection molding a resin on the coupling member 30, the end portion of the pull cord is fixed inside the auxiliary operating element 40, and the auxiliary operating element 40 is generally elongated in shape corresponding to the longitudinal direction of the slide fastener. The user's finger pinches the auxiliary operating member 40, thereby pulling the slider, and the point of application of force of the user is concentrated on the auxiliary operating member 40. The ring type injection molded pull tab can avoid the problem that the pull rope is opened in the ring type pull tab, but the ring type injection molded pull tab has the following problems when in use:

1. when the user pulls the slider, the fingers of the user can often contact and rub the connecting piece 30 formed by the pull rope, and the use experience degree is reduced.

2. The coupling 30 formed of the pull cord is soft and the auxiliary operating element 40 is hard, so that when the auxiliary operating element 40 is pulled, the auxiliary operating element 40 is easily deviated from the opening and closing direction of the slide fastener, and the biasing force is dispersed, resulting in low operability.

3. The auxiliary operating member 40 is in a strip shape, so the volume of the auxiliary operating member 40 is small, the operating area between the fingers of the user and the auxiliary operating member 40 is still small, the user still cannot apply a strong force to pull the pull tab 20, and the phenomenon that the waterproof zipper cannot be opened or closed smoothly still exists.

4. The auxiliary operating member 40 is a one-time injection molded part and is injection molded at the end of the pull cord, so the auxiliary operating member 40 is fixedly connected with the pull cord, and the auxiliary operating member 40 cannot be replaced; when the auxiliary operating member 40 is damaged, the pull cord and the auxiliary operating member 40 cannot be replaced, resulting in the entire tab being discarded. Further, when the auxiliary operating element 40 is fixedly connected to the cord, the length of the cord is fixed and cannot be adjusted, and the dual-purpose property is poor.
