Description
- The present invention relates to a bag body, and more particularly to a rectangular bag.
- Since a rectangular bag is rectangular in shape, it could easily receive items such as documents or a laptop computer, making it very versatile and thus widely used. A conventional rectangular bag is typically provided with a zipper to seal an opening of a bag body thereof. However, the opening of a bag might be left open by negligence, so the items inside the bag may fall out of the bag body. In addition, an unsealed opening would make the bag become a coveted target for thieves and burglars, which might even endanger the life and the property of the user.
- Also, sometimes even when the zipper of the bag body is zipped, the zipper might be unknowingly zipped open, causing the user to suffer heavy losses.
- Furthermore, the design of the bag strap and the bag body of a conventional rectangular bag available on the market usually restricts the body of the user from moving freely. Thus, in all aspects, the rectangular bag still has room for improvements.
- In view of the above, the primary objective of the present invention is to provide a rectangular bag, which provides a good anti-theft function.
- To achieve the objective of the present invention, the present invention provides a rectangular bag, including a bag body, a first zipper, and a strap, wherein the bag body has a top panel, a left side panel, and a right side panel. The left side panel and the right side panel are provided on opposite sides. Two ends of the top panel are respectively connected to the left side panel and the right side panel. A first opening is provided on the left side panel. The first zipper includes a first chain and a first slider, wherein the first chain is provided on a peripheral edge of the first opening, and has a first end and a second end. The first end of the first chain is closer to the top panel than the second end thereof is. The first slider is provided on the first chain, wherein the first slider is movable along the first chain. When the first slider is located at the first end of the first chain, the first opening is sealed by the first chain; when the first slider is located at the second end of the first chain, the first opening is unsealed. An end of the strap is connected to the first slider, and another end thereof is connected to the right side panel.
- With the aforementioned design, when the rectangular bag is shouldered or carried on the back, the bag body would subside relative to the strap because of the effects of gravity, pulling the first slider to move toward the first end of the first chain, whereby to seal the first opening. In addition, since the strap and the bag body should have a relative movement before unsealing the first opening, which could be done by moving the strap or the bag body before opening the zipper, the user would instantly notice the unusual feeling that a weight of the rectangular bag is changed once the strap or the bag body is pulled. Whereby, the rectangular bag could provide an anti-theft function.

FIG. 7 is a partial enlarged view, showing the left side panel of a fifth embodiment of the present invention. - A
rectangular bag 100 of a first embodiment of the present invention is illustrated inFIG. 1 andFIG. 2 , including abag body 10, afirst zipper 20, and astrap 30. - The
bag body 10 has atop panel 12, aleft side panel 14, and aright side panel 16, wherein theleft side panel 14 and theright side panel 16 are provided on opposite sides. Two ends of thetop panel 12 are respectively connected to theleft side panel 14 and theright side panel 16. Afirst opening 140 is provided on theleft side panel 14, wherein thefirst opening 140 communicates with a storage space of thebag body 10. - The
first zipper 20 includes afirst chain 22 and afirst slider 24, wherein thefirst chain 22 are provided on a peripheral edge of thefirst opening 140. Thefirst chain 22 have afirst end 222 and asecond end 224, wherein thefirst end 222 of thefirst chain 22 is closer to thetop panel 12 than thesecond end 224 thereof is. Thefirst slider 24 is provided on thefirst chain 22, wherein thefirst slider 24 is movable along thefirst chain 22. When thefirst slider 24 is located at thefirst end 222 of thefirst chain 22, thefirst opening 140 would be sealed by thefirst chain 22; when thefirst slider 24 is located at thesecond end 224 of thefirst chain 22, thefirst opening 140 would be unsealed, for thefirst chain 22 is opened. Whereby, items could be put into or retrieved from the storage space of thebag body 10 through thefirst opening 140. - An end of the
strap 30 is connected to thefirst slider 24, while another end thereof is connected to theright side panel 16. In the first embodiment, thefirst slider 24 has a perforation. One end of thestrap 30 is connected to a connector, which is aclasp 32 as an example, wherein theclasp 32 could be clasped with the perforation of thefirst slider 24. In this way, one end of thestrap 30 could be detachably connected to thefirst slider 24 through theclasp 32. In other embodiments, the end of thestrap 30 could be also detachably connected to thefirst slider 24 through different kinds of connectors. However, the type of the connector is not a limitation of the present invention. - When the
rectangular bag 100 is shouldered or carried on the back, thebag body 10 would subside relative to thestrap 30 because of the effects of gravity, pulling thefirst slider 24 to move toward thefirst end 222 of thefirst chain 22, whereby to seal thefirst opening 140. In other words, with the aforementioned design, when therectangular bag 100 is shouldered or carried on the back, thefirst zipper 20 of therectangular bag 100 could be automatically closed by gravity, which ensures thefirst opening 140 to be sealed. - In addition, if someone tries to pull down the
first zipper 20 to unseal thefirst opening 140, one end of thestrap 30 has to be moved from thefirst end 222 toward thesecond end 224 of thefirst chain 22. That means the strap 30 (or at least one end of the strap 30) and thebag body 10 should have a relative movement before unsealing thefirst opening 140, which could be done by moving thestrap 30 or thebag body 10. In other words, a thief who tries to open thefirst zipper 20 would pull either thestrap 30 or thebag body 10, and therefore, the user would instantly notice the unusual feeling that a weight of the rectangular bag is changed. In this way, therectangular bag 100 could provide an anti-theft function. - It is worth mentioning that, in order to make the user move more freely when the
rectangular bag 100 is shouldered or carried on the back, therectangular bag 100 is designed as shown inFIG. 3 , wherein a shortest distance between thefirst end 222 of thefirst chain 22 and an extended surface of thetop panel 12 is defined as a first distance L1, and a shortest distance between the extended surface of thetop panel 12 and a junction of thestrap 30 and theright side panel 16 is defined as a second distance L2, satisfying the following condition: L2>L1. In addition, thebag body 10 has abottom panel 18 provided on a side opposite to thetop panel 12, wherein a shortest distance between thebottom panel 18 and a junction of thestrap 30 and theright side panel 16 is defined as a third distance L3, which satisfies the following condition: L2>L3>L1. In other words, when thebag body 10 stands vertically, two ends of thestrap 30 thereof are not at the same height. Whereby, thebag body 10 would not sway easily when therectangular bag 100 is in use. - Also, a shortest distance between the
top panel 12 and thebottom panel 18 is defined as a fourth distance L4, satisfying the following condition: L1≤⅕ L4. In such a condition, thefirst slider 24 would be closer to thetop panel 12 of thebag body 10 when thestrap 30 is shouldered or carried on the back, whereby to stabilize thebag body 10. Therefore, thebag body 10 would not sway easily. - Furthermore, the third distance L3 is preferable to be greater than a fifth of the fourth distance L4 without exceeding a half of the fourth distance L4, which means the third distance L3 satisfies the following condition: ⅕ L4<L3≤½ L4. By making the third distance L3 greater than a fifth of the fourth distance L4, the center of gravity of the
bag body 10 would be at a lower position when therectangular bag 100 is carried, which could prevent thebag body 10 from rotating. On the other hand, by restricting the third distance L3 from exceeding a half of the fourth distance L4, more space could be provided between thestrap 30 and thebag body 10 when therectangular bag 100 is in use, allowing more comfortable and more flexible movements. - In other words, by changing a position of the junction of the
strap 30 and thebag body 10, the space surrounded by thestrap 30 would be greater than that of a conventional rectangular bag, which could make the user able to move more comfortably and more flexibly without being restricted. - A
rectangular bag 200 of a second embodiment of the present invention is illustrated inFIG. 4 . The difference between therectangular bag 200 of the second embodiment and that of the first embodiment is that, a second opening is provided on abag body 210 thereof, wherein the second opening extends from a right side panel 216 to atop panel 212. Therectangular bag 200 further includes asecond zipper 240, wherein thesecond zipper 240 includes asecond chain 242 and asecond slider 244. Thesecond chain 242 are provided on the peripheral edge of the second opening, and have afirst end 242 a and asecond end 242 b. Thefirst end 242 a of thesecond chain 242 is located on thetop panel 212, and thesecond end 242 b of thesecond chain 242 is located on the right side panel 216. Thesecond slider 244 is provided on thesecond chain 242, wherein thesecond slider 244 is movable along thesecond chain 242. When thesecond slider 244 is located at thefirst end 242 a of thesecond chain 242, thesecond chain 242 would seal the second opening; when thesecond slider 244 is located at thesecond end 242 b of thesecond chain 242, thesecond chain 242 would unseal the second opening. In addition, it is preferred to have the second opening communicating with the first opening, and a first end of thefirst chain 222 being connected to one end of thesecond chain 242. With such design, the user could freely adjust the positions of thefirst zipper 20 and thesecond zipper 240 to be able to retrieve items from thebag body 10 or to put items into thebag body 10 in a convenient and preferred way. - An end of a
strap 230 of the second embodiment is also engaged with thefirst slider 224 as described in the first embodiment. Therefore, thefirst zipper 20 of therectangular bag 200 could be also automatically closed by the effects of gravity when therectangular bag 200 is shouldered or carried on the back. In addition, thefirst slider 224 would be moved to a junction of the left side panel 214 of thebag body 210 and thetop panel 212 because of the effects of gravity when therectangular bag 200 is carried.
