Luggage comprising a zipper

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

[0001] The present invention relates generally to a luggage using a zipper.

2. Description of the Related Art

[0002] FIG. 1 shows a perspective view of a luggage using a conventional zipper and FIG. 2 is a sectional view taken along line 2-2 of FIG. 1. As shown in FIGS. 1-2, the luggage 1 mainly comprises a first half shell 2, a second half shell 3, a zipper 4 installed between the first and second half shells 2 and 3 for joining the half shells 2 and 3, and two end strips 5 respectively mounted to the periphery edges of the first and second half shells 2 and 3 and connected with two fabric tapes 4a of the zipper 4 respectively. In addition to the fabric tapes 4a, the zipper 4 further includes a plurality of interlockable teeth 4b mounted on the two fabric tapes 4a in two rows and a slider 4c reciprocally moveable along the path defined by the two rows of the teeth 4b. By means of the engagement or disengagement of the interlockable teeth 4b of the zipper 4, the first and second half shells 2 and 3 can joined together or separated from each other. The end strips 5 are used to cover the unprocessed end edges of the first and second half shells 2 and 3 and the stitching line, showing a sense of beauty for the luggage.

[0003] In production of the aforesaid conventional luggage, the stitching work is carried out and can be done perfectly only after the three elements, i.e. the fabric tape of the zipper, the end strip and the half shell, are well aligned one to another. However, the correlative positions of the aforesaid three elements can hardly be maintained in a stable manner during the whole stitching work, resulting in that the fabric tape of the zipper may offset away from a predetermined rectilinear path where the tape is supposed to be located, which in turn results in that the slider can not move along the teeth smoothly, lowering the yield rate in production of the luggage. In addition, the fabric tape stitched on the luggage will tend to be torn and then separated from the half shell after a long time of use due to the pull force acting thereon. GB 1 438 231 discloses a slide fastener stringer for adhesive attachment to a garment. The slide fastener stringer comprises a tape, a reinforcing cord about which the tape is folded longitudinally on itself to form a double ply structure having two tape plies and embracing therein said reinforcing cord, fastener elements secured to said tape along the fold, an adhesive coating applied over the inner face of each of said tape plies. It is desired to provide an improved zipper for use in a luggage.

SUMMARY OF THE INVENTION

[0004] The present invention has been accomplished in view of the above-noted circumstances. It is therefore an objective of the present invention to provide a luggage comprising a zipper which is simple in its construction and has less elements so as to simplify the process of making the luggage.

[0005] Another objective of the present invention is to provide a luggage comprising a zipper which is durable in use.

[0006] To attain the above-mentioned objectives, a luggage is provided, said luggage comprising: a first half shell; a second haft shell, and a zipper installed between the first and second half shells of the luggage, the zipper comprising:

a first tape made of plastic material and having a shielding section for covering an end edge of the first half shell of the luggage, a mounting section connected with the shielding section for mounting to the first half shell in a way that the end edge of the first half shell) is received between the shielding section and the mounting section, and an extension section connected with the shielding section;

a second tape made of plastic material and having a shielding section for covering an end edge of the second half shell of the luggage, a mounting section connected with the shielding section of the second tape for mounting to the second half shell in a way that the end edge of the second half shell is received between the shielding and the mounting section of the second tape, and an extension section connected with the shielding section of the second tape; and

a plurality of interlockable teeth mounted respectively on the extension sections of the first and second tapes in two rows, characterized in that the mounting section of the first tape is stitched on the first half shell by a stitching line in a way that the stitching line is covered by the shielding section of the first tape; wherein the mounting section of the second tape is stitched on the second half shell by a stitching line in a way that the stitching line is covered by the shielding section of the second tape.

DETAILED DESCRIPTION OF THE INVENTION

[0009] As shown in FIGS. 3 and 4, a zipper 10 provided according to a preferred embodiment of the present invention is used to be installed between a first half shell 2 and a second half shell 3. The zipper 10 comprises mainly a first tape 20, a second tape 30 and a plurality of interlockable teeth 40 arranged in two rows.

[0010] The first tape 20 is made of plastic material, such as polyvinyl (PVC), polypropylene (PP), polyethylene (PE), polycarbonate (PC), and the like. The first tape 20 has a shielding section 21, an extension section 23 and a mounting section 25, which are all integrally connected. An end of the shielding section 21 and an end of the mounting section 25 are integrally joined so as to jointly define a C-shaped restriction portion 27 therebetween. The extension section 23 extends outwardly from an outer surface of the joint where the shielding section 21 and the mounting section 25 are integrally connected to each other.

[0011] The structure and material of the second tape 30 are the same as those of the first tape 20. That is, the second tape 30 also has a shielding section 31, an extension section 33 and a mounting section 35, and a restriction portion 37 is defined at the joint where the shielding section 31 and the mounting section 35 are integrally connected to each other.

[0012] The teeth 40 each have an engageable end 41, through which the teeth 40 can be interlocked, and a mounting end 43, which is mounted either on the extension section 23 of the first tape 20 or the extension section 33 of the second tape 30 by stitching or other appropriate way.

[0013] As shown in FIG. 4, when the zipper 10 of the present invention is installed in a luggage, the end edge of the first half shell 2 is received between the shielding section 21 and the mounting section 25 of the first tape 20 and stopped at the restriction portion 27, thereby determining precisely the position where the first tape 20 should be mounted to the first half shell 2. After the first tape 20 is aligned with the first half shell 2, the mounting section 25 is sewn on the first half shell 2 by a stitching line L1 in such a way that the stitching line L1 is covered and well protected by the shielding section 21 of the first tape 20. It will be appreciated that the way of fastening the first tape 20 to the first half shell 2 is not limited to aforesaid stitching. For example, adhesive mounting, snap mounting or the like can be used.

[0014] Similarly, the second tape 30 can be fastened to the second half shell 3 by the way described in the above paragraph, such that the stitching line L1 for stitching the second tape 30 is also covered and well protected by the shielding section 31 of the second tape 30. As a result, the unprocessed end edges of the first and second half shells 2 and 3 will be respectively hidden between the shielding sections 21 and 31 and the mounting section 25 and 35 of the first and second tapes 20 and 30. In addition, by means of stopping the end edges of the first and second half shells 2 and 3 against the restriction portions 27 and 37 respectively, the first and second tapes 20 and 30 can be precisely aligned with the first and second half shells 2 and 3 respectively and the alignment can be maintained stably during the stitching work.

[0015] As indicated above, the zipper provided by the present invention combines the conventional individual end strip and zipper tape into a unit; therefore, the stitching work can be carried out after the alignment of the zipper to the shell of the luggage is simply done. On the other hand, in the process of making the conventional luggage, the stitching work can be carried out only after the conventional zipper, end strip and luggage shell are all aligned one to another. In other words, the zipper of the present invention can effectively minimize the process of assembling the luggage, and the zipper of the present invention can be easily maintained along a rectilinear path upon and after stitching such that the potential problem of unsmooth movement of the slider of the conventional zipper can be prevented so as to enhance the yield rate in production of the luggage. Besides, since the tapes of the zipper of the present invention are made of soft plastic material, the zipper of the present invention will be more durable in use and won't be easily torn upon receiving a pull force under a long time of use.
