Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the technical field of zippers, and in particular to a zipper slider attached to a zipper of a backpack, handbag or cabin luggage, and a pull-tab and a fixing structure thereof that can fix the zipper slider to the backpack, handbag or cabin luggage when the zipper is closed.

2. Description of the Related Art

Today's backpacks, handbags or cabin luggage usually have a zipper opening, allowing users to easily open and close the zipper opening. However, the zipper slider used to close the zipper is a sliding element, so it is easy to slide open. For example, when the backpack is filled with too many items and the zipper is stretched tight, it is easy to cause the zipper slider to slide open. In addition, if the zipper slider is not fixed at all, a thief can easily open the zipper slider and then reach into the bag to steal items. This shows that simply closing the opening of the bag with a zipper is not safe enough.
In order to overcome the problem that the zipper of the zipper opening may slide open by itself, the known technology usually adds a lock to the zipper slider, such as shown in U.S. Pat. No. 7,979,964B2, which is designed with a keyless lock on the two zipper sliders, which enables the two zipper sliders to be locked together when they are brought together. However, its lock structure is too complicated and is integrally molded with the zipper slider, so its manufacturing cost is too high. In addition, U.S. Pat. Nos. 10,010,144B2 and 9,854,890B2 also design a zipper lock, which uses a buckle to buckle the pull-tabs of the two zipper sliders when the two zipper sliders are close together. U.S. Pat. No. 8,307,518B2 designs a more complex zipper slider, which implements the pull-tab into a combination lock structure. In fact, today's backpacks, handbags and cabin luggage are all items that users carry with them. A simple and practical zipper slider fixing structure can achieve the effect of anti-theft and preventing the zipper from loosening, without the need for overly complicated locks. Overly complicated locks often make users feel inconvenienced and give up using them, which is equivalent to turning the lock into a decorative item. Therefore, how to create a simple and practical zipper slider lock with basic anti-theft functions is the problem to be overcome by the present invention.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a pull-tab structure with anti-theft effect, which is designed by attaching a pull-tab structure to the zipper slider body so that the pull-tab has an anti-theft buckle plate. When the pull-tab is applied to the zipper of a backpack, handbag or cabin luggage, the pull-tab can be fixed to the backpack, handbag or cabin luggage through the anti-theft buckle plate when the zipper is closed, thereby achieving the effect of preventing the zipper slider body from moving and preventing theft.
Another object of the present invention is to provide a fixing structure of a pull-tab structure with an anti-theft effect, wherein an accessory is provided on the surface of a backpack, a handbag or a cabin bag, so that the pull-tab can be inserted into the accessory and the anti-theft buckle plate is clamped on the accessory, thereby achieving the effect of conveniently fixing the pull-tab.
The pull-tab structure with anti-theft effect and its fixing structure can be installed on the zippers of backpacks, handbags and cabin luggage, etc. When the two zipper slider bodies are linked together to close the zipper opening, the pull-tab is inserted under the accessory, and the anti-theft buckle plate clamps the accessory between it and the pull-tab to form a structure that fixes the pull-tab. This allows the zipper slider bodies to be basically fixed, making the zipper slider bodies difficult to slide or be pulled apart by thieves, and can also achieve the function of conveniently fixing the pull-tab.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the present invention discloses a pull-tab structure with anti-theft effect, which is used to be combined with a zipper slider body 30. The preferred embodiment thereof comprises: a pull-tab 10 and an anti-theft buckle plate 20. One end of the pull-tab 10 has a connecting portion 11. The connecting portion 11 can be an integrally formed hole 111, a ring or other structure. The connecting portion 11 is used to be coupled to the zipper slider body 30. The anti-theft buckle plate 20 is a one-piece body, and a first end of the anti-theft buckle plate 20 is coupled to the pull-tab 10 so that the anti-theft buckle plate 20 is located on one surface of the pull-tab 10 and a receiving portion A1 is formed between the anti-theft buckle plate 20 and the pull-tab 10. An opposing second end of the anti-theft buckle plate 20 is not fixed to the pull-tab 10 and forms an opening A2 connected to the receiving portion A1, so that the anti-theft buckle plate 20 and the pull-tab 10 can clamp an object passing through the receiving portion A1 (as shown in FIG. 11 to FIG. 13 ).
Referring to FIG. 4 , the first end of the anti-theft buckle plate 20 may be integrally formed on the pull-tab 10. Referring to FIG. 5 and FIG. 6 , the first end of the anti-theft buckle plate 20 can also be implemented as a structure assembled to the pull-tab 10 through an assembly structure. A preferred embodiment of the assembly structure includes providing a slit 12 in the pull-tab 10 so that the first end of the anti-theft buckle plate 20 is tightly inserted into the slit 12 and fixed. The assembly structure may also use other known fixing elements to fix the first end of the anti-theft buckle plate 20 to the pull-tab 10, and the same purpose and function can be achieved.
More specifically, the pull-tab 10 may be provided with a hollow portion 13 connecting the front and back surfaces thereof. The anti-theft buckle plate 20 is disposed on the hollow portion 13, so that the first end of the anti-theft buckle plate 20 is integrally formed on an inner wall of one end of the hollow portion 13, or assembled to the inner wall of one end of the hollow portion 13 through the above-mentioned assembly structure. For example, the hollow portion 13 is provided with a slit 12 connected to the front end of the pull-tab 10, and the first end of the anti-theft buckle plate 20 is inserted into the slit 12 in a tight fit and fixed.
Referring to FIG. 1 and FIG. 3 , the anti-theft buckle plate 20 is preferably a stamped elastic plate, for example, a spring steel plate is stamped to form a connecting plate portion 21, a buckle plate portion 22 and a guide plate portion 23 integrally formed from the first end to the second end of the anti-theft buckle plate 20. The connecting plate portion 21 is obliquely coupled to the pull-tab 10. The buckle plate portion 22 is slightly parallel to one side of the pull-tab 10 to form a receiving portion A1 located between the anti-theft buckle plate 20 and the pull-tab 10. The guide plate portion 23 is obliquely away from one side of the pull-tab 10 to form an opening A2, thereby facilitating clamping and fixing other objects.
In addition, please refer to FIG. 7 , which is a side view schematic diagram of the second embodiment of the anti-theft buckle plate 20 of the present invention, showing that the front end of the guide plate portion 23 of the present invention can be further bent toward the center of the pull-tab 10 to form a small folding piece portion 24.
Referring to FIG. 8 , it is a side view schematic diagram of a third embodiment of the anti-theft buckle plate 20′ of the present invention. The anti-theft buckle plate 20′ can be a straight plate with a front end bent inward to form a stopper 25, which can be used to make the object clamped by the anti-theft buckle plate 20′ more difficult to escape. Referring to FIG. 9 and FIG. 10 , there are schematic side views of an embodiment of the pull-tab 10 of the present invention having two anti-theft buckle plates, wherein an anti-theft buckle plate 20′ (or 20) is provided on each side of the pull-tab 10, so that the anti-theft buckle plate 20′ (or 20) can be used to clamp other objects no matter which side the pull-tab 10 is turned to.
Referring to FIG. 11 and FIG. 12 , the present invention also proposes a pull-tab fixing structure, and a preferred embodiment thereof comprises: the above-mentioned pull-tab 10 and the anti-theft buckle plate 20 and a bag 40. The bag 40 can be a backpack, a handbag or a cabin bag. The bag 40 is provided with a zipper 50 and one or two zipper sliders 30 for closing and opening the opening 41 thereof. An accessory 43 is additionally provided on a bag surface 42 next to the opening 41 (zipper 50). Referring to FIG. 13 , one of the preferred embodiments of the accessory 43 may be a belt 431 coupled to the bag surface 42, such as a woven belt, an elastic belt or a plastic belt. When the belt 431 is combined with the bag surface 42, one of the preferred embodiments is to sew it on the bag surface 42 at intervals through stitches 432 to form a plurality of loop portions 433 into which the pull-tab 10 can be selectively inserted, so that the anti-theft buckle plate 20 or 20′ can be clamped in one of the loop portions 433. In other embodiments, the accessory 43 may also be other metal sheets bonded to the bag surface 42.
FIG. 14 and FIG. 15 show another embodiment in which the accessory 43 is implemented as a belt 431. The belt 431 is sewn to the bag surface 42 at intervals through stitches 432. The stitches 432 are oblique stitches sewn on the belt 431 and the bag surface 42, so that each loop portion 433 presents a unique trapezoidal shape and function.
Thereby, the connecting portion 11 of the pull-tab 10 is coupled to the zipper slider body 30 on the bag 40, so that the user can pull the pull-tab 10 to move the zipper slider body 30. When the zipper slider body 30 moves to a position to close the opening 41, the pull-tab 10 can be inserted into the accessory 43, for example, below the selected loop portion 433 of the belt 431. The anti-theft buckle plate 20 then clamps the accessory 43 between the receiving portion A1 of the anti-theft buckle plate 20 and the pull-tab 10 to form a fixing structure for fixing the pull-tab 10, so that the zipper slider body 30 is basically fixed, and is not easy to slide or be pulled apart by thieves, and can achieve the effect of conveniently fixing the pull-tab.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
