Backpack {Backpack}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backpack, and more particularly, to a convenient backpack that does not need to carry a sleeping bag separately by configuring the backpack to have a function of a sleeping bag by expanding an endothelium while maintaining its shape.

It should be noted that the following description merely provides background information related to the embodiment of the present invention and does not constitute the prior art.

Generally, a backpack or backpack is a kind of bag made of cloth or leather that can be put on the back. Today, most of them are made of chemical fibers such as vinyl and nylon.

The backpack is developed in Central Europe, and its type varies depending on the position, shape, size, number and position of the back pocket. Since there is a new backpack with a metal frame, it can be selected appropriately according to the user's body type, physical fitness, and usage.

If you have a lot of luggage, there is a danger of walking, so you have to be careful if you are 20kg for ordinary people and 30kg for expert. When the backpack is tied, it is recommended that the center of gravity of the load be mostly packed near the shoulder position, and the strap should be hooked on the back of the strap so that the load is attached to the back. Packing is made so that the soft part is placed on the side of the back, and the contents are treated so that it does not get wet with a small pouch of vinyl. Immediate items such as maps, flashlights, water bottles, rain boots and emergency foods are put in easy-to-take-out pockets.

The structure of the backpack usually includes a shell and a suspender formed on the front of the shell to be hung on the shoulder of the user. The shell has a cylindrical housing part constituting the inside thereof and an opening part serving as an inlet of the housing part . Further, if necessary, the backpack may further include one or more pouches which can be separately housed in the outer shell, and a connection ring that can accept various utensils.

In such a backpack, the user stores various articles, foods, necessary clothes, and the like in the housing portion of the outer shell. Especially when camping, a sleeping bag is required. Such a sleeping bag is carried with the backpack.

However, since the sleeping bag is so bulky, carrying a sleeping bag separately from the backpack is troublesome and troublesome.

Therefore, the embodiment of the present invention has a main purpose of providing a backpack having a function of a sleeping bag.

Another object is to provide a backpack configured to accommodate a large amount of contents in various ways.

A backpack according to an embodiment of the present invention includes: a tubular envelope capable of containing contents; And an end plate having one end connected to the opening of the shell and extending in the longitudinal direction of the shell in a state that the shell is extended outward from the shell.

According to another aspect of the present invention, there is provided a backpack comprising: a tubular envelope capable of containing contents; An inner skin having one end connected to an opening of the outer skin and extending in a lengthwise direction of the outer skin in a state in which the outer skin is expanded outward; And a detachable lid connected to the outer shell through a connection cord.
According to another aspect of the present invention, there is provided a backpack comprising: a tubular envelope capable of containing contents; And an inner skin which is connected to an opening of the outer skin so as to extend in a longitudinal direction of the outer skin in a state in which the outer skin is extended outside the outer skin, And the width adjusting means is provided on the outer side of the inner skin at an angle inclined with respect to the longitudinal central axis of the outer skin or the inner skin and is arranged on one side substantially in parallel with the flaring side edge of the inner skin, And a second width adjusting means disposed symmetrically with respect to a center axis with respect to the first width adjusting means and the first width adjusting means attached to the first width adjusting means and the second width adjusting means, And the first width adjusting means and the second width adjusting means are disengaged from each other, The width of the upper portion of the inner skin is adjusted so as to be greater than the width of the lower portion so that the upper body of the inner body can be inserted, And a substantially inverted triangular ventilation part for venting at least the longitudinal center part of the upper body of the user to the outside is formed between the width adjusting means.

As described above, according to the embodiment of the present invention, since the backpack can be used as the sleeping bag, there is no need to carry the sleeping bag separately.

According to the embodiment of the present invention, since the lid is configured to be detachable from the backpack, it is possible to store and carry a large amount of contents.

Further, according to the embodiment of the present invention, the size of the storage portion of the backpack can be adjusted by folding the inner skin inward and easily adjusting the extension length of the inner skin.

Is a front view showing a state in which the inner skin of the backpack according to the embodiment is expanded and used as a sleeping bag.

As shown in these drawings, the backpack 100 according to the embodiment of the present invention includes a tubular envelope 10 into which contents can be inserted; And an inner skin 20 extending in the longitudinal direction of the outer skin 10 in a state where one end is connected to the opening 11 of the outer skin 10 in an expanded state.

The housing 10 is formed with a housing portion in which various articles, foods, clothes, and the like are housed, and an opening 11 is provided at an upper portion thereof. A suspender 12 (see FIG. 6) is provided on one side of the outer skin 10 so as to be hooked on the shoulder of a person who pockets the backpack 100. Since this structure is a basic structure of the backpack, a detailed description thereof will be omitted.

The opening 11 of the shell 10 can be opened so that various contents can be stored in the storage portion. In particular, when the opening 13 is provided inside the rim of the opening 11 and the opening 11 is to be sealed, both ends of the string 13 are pulled and then bundled or fixed with a clip to fix the length, .

At the opposite side of the suspenders 12 on the outer skin 10, one or more pouches which can be separately accommodated, and a connecting ring capable of accepting various tools can be additionally provided. For example, as shown in the figure, a first bag 16 is provided on the opposite side of the suspenders 12 from the envelope 10, and a second bag 17 is provided on one side or both sides of the envelope 10 . The first bag (16) or the second bag (17) is provided with an article that can be easily taken out and used, such as a medical product, a map, a flashlight, a bucket, and other miscellaneous goods. Particularly, the first bag 16 can be used to store or place a bulky item such as a small chair or the like. The first bag 16 or the second bag 17 may be formed of a mesh-like material such as a net, and each bag may be provided with a band of elastic material at the tip of the opening so that the size of the opening of the bag can be stretched But the present invention is not limited thereto.

Further, a plurality of grip straps 18 may be provided on both sides of the outer casing 10. [ The strap 18 can also serve as a hook for hanging the clasped article. As shown in Fig. 1, when the second bag 17 is accommodated in the second bag 17 with an item extending over the height of the second bag 17, such as a water bottle, It can also play a supporting role. The auxiliary strap 19 may be made of an elastic material.

One end of the endcap 20 is connected to the opening 11 of the envelope 10 so as to extend in the longitudinal direction of the envelope 10. Since the inner skin 20 can be folded inwardly of the outer skin 10, there is an advantage that the extension length of the inner skin 20 can be adjusted. The other end of the end plate 20 forms an inlet 21 into which a person can enter when it is used as a sleeping bag. In order to narrow the size of the inlet 21, the inlet 21 is provided with a strap 23 inside the rim. In this case, the length of the strap 23 is fixed by pulling both ends of the strap 23, So as to narrow the inlet 21. It is preferable that such a strap 23 allows a person inside the strap to directly fasten and fix the inlet 21 in a state where a person is inside the backpack 100 when the backpack 100 is used as a sleeping bag . The backpack 100 will provide sufficient warmth even in the sub-zero weather because the nappy 20 is wrapped around the head while the person is lying down and the mouth 21 is tightened with the strap 23. In addition, at least a part of the inner film 20 may be made of a waterproof or moisture-proof material.

As shown in FIG. 2, it is preferable that the inner skin 20 is formed to be much longer than the length of the outer skin 10. This is because the inner skin 20 should be made longer than at least the outer skin 10 because the outer skin 10 is made to have a length that can extend from the waist to the head or above the height when the user wears the backpack 100 When you use it as a sleeping bag, you can cover up enough people. However, the present invention is not limited thereto, and the length of the inner skin 20 may be adjusted by adjusting the length of the outer skin 10 accordingly.

Further, on the outer surface of the inner skin 20 (the side remote from the person in the inner skin when the inner skin extends in the longitudinal direction and the person is in the longitudinal direction) It is also possible to adjust the width of the inner tube 20 so that the width becomes narrower or wider.

3, by providing the width adjusting means such as the slide fastener 22, the inner film 20 can be held in the folded state (see Fig. 2) so as to narrow the width, Can have a cross-sectional area substantially the same as that of the opening 11 of the shell 10. [0064] Here, the slide fastener 22 may be made of a material such as metal or plastic.

As the width adjusting means, it is possible to use, in addition to the slide fastener, a Velcro tape called a magic tape, a snap button called a so-called knot button, or the like.

Specifically, the inner film 20 is formed in such a shape that the opening 21 is opened so that the cross-sectional area constituted by the front end of the inlet 21 becomes wider than the sectional area constituted by the front end connected to the opening 11. The first slide fastener 22a is inclined at an angle of inclination with respect to the longitudinal central axis of the outer shell or the inner skin in the outer side surface of the inner skin 20 100a, respectively. The second slide fastener 22b is attached to the other side symmetrically with respect to the center axis.

As the first and second slide fasteners 22a and 22b are engaged with each other, the inner film 20 is maintained in the folded state as described above. On the other hand, by releasing the engagement of the first and second slide fasteners 22a and 22b, when the backpack 100 is used as a sleeping bag, the shoulder portion of the human can smoothly enter the inner skin 20, Can move.

At least a part of the inner skin 20 (the portion partitioned by the inverted triangle between the slide fasteners in Fig. 3) between the first and second slide fasteners 22a and 22b is provided with a through- (24). The ventilation part 24 can smoothly circulate air in the air when the backpack 100 is used as a sleeping bag and smoothly circulates the air so that the user can stably breathe in the backpack 100 And provides an advantage that sweat or other moisture generated by the user at the time of sleeping is smoothly discharged to maintain a dry state.

A state in which the backpack 100 according to the embodiment of the present invention can be unfolded and used as a sleeping bag is shown in Fig. When the inner skin 20 is extended from the outer skin 10 in the form of a trumpet, the backpack integrated sleeping bag is formed which allows a person to lie down. Of course, it is also possible to insert another sleeping bag into the backpack 100 to maximize the warmth.

The inlet 21 of the inner skin 20 and the portion adjacent thereto are in contact with the inner surface of the outer skin 10 when the inlet 21 is narrowed and folded into the outer skin 10 with the slide fastener 22 engaged. 10 at the bottom of the shell 10. Thus, the backpack 100 according to the embodiment of the present invention can function as a backpack. Here, the contents accommodated in the inside of the casing 10 are located in contact with the outer surface of the inside casing 20. The length of the extension of the inner skin 20 can be adjusted by adjusting the length of the inner skin 20 folded inwardly as the inner skin 20 can be folded inwardly of the outer skin 10 as described above, Accordingly, even if the content is large, the inner film 20 can cover the contents. Further, when the inner cover 20 is completely inserted into the outer casing 10, the backpack is reinforced to have the double-walled sidewalls, thereby significantly improving the durability.

In the backpack 100 according to the embodiment of the present invention, the envelope 10 may further include a cover 30 connected via a connection cord 31. [ The connection cord 31 can adjust its length. In addition, the lid 30 functions as a separate receivable pouch. The lid 30 may be detachably connected to the shell 10 in addition to the connecting cord 31 and connected to the connecting portion 32 extending from the shell 10. For example, a velcro tape 33a called magic tape is attached to the free end of the connecting portion 32, and a Velcro tape 33b is attached to one end of the cover 30 corresponding to the Velcro tape 33a. Adhesion of the tape allows the lid 30 to be connected to the shell 10. This connection relationship is schematically shown in Fig. Instead of the velcro tape, a slide fastener or a snap button or the like may be employed.

The lid 30 is connected by the connecting portion 32 and the connecting strap 31 so as to cover and cover the upper portion of the enclosure 10 when the enclosure 10 accommodates contents of a predetermined reference capacity or less.

FIG. 4 is a front view schematically showing a state in which the size of the storage unit is increased until the backpack has a capacity exceeding the reference capacity according to the embodiment of the present invention, and FIG. 5 is a cross- Is a front view showing a state in which a backpack according to an embodiment of the present invention accommodates a large-capacity contents.

Occasionally, a rucksack may contain the contents in excess of its inherent reference capacity. The backpack 100 according to the embodiment of the present invention exerts an excellent effect of containing the contents in excess of the reference capacity. At least a part of the inner skin 20 put inside the outer skin 10 is covered with the outer skin 10 so that the capacity of the backpack 100 can be increased.

Referring to FIGS. 4 and 5, it can be seen schematically that the size of the storage compartment is increased until the backpack exceeds the reference capacity and stores a large amount of contents. At this time the inlet 21 of the endothelium 20 is still located inside the envelope 10 and the connection 32 is separated from the lid 30 due to its limited length, Can still be connected to the shell (10) via a connecting cord (31).

In this case, after the end portion of the end portion 20, which is extended to a sufficient length, is appropriately folded at the opening end extending upward by the folded end of the end portion 20, The connecting cord 14 (see Figs. 2 and 3) is caused to cross the folded inner skin 20 to be fastened to the other side of the outer skin 10, for example, the connecting portion 15 of the suspender 12 (see Fig. 6). Next, the lid 30 is covered and then the lanyard 30 is connected to the lid 30 by connecting the lanyard 30 to the lid 30. Thus, even if the capacity of the contents stored in the backpack 100 is greatly increased, the inner bag 20 can be covered with the extendable inner liner 20 and the lid 30 which can be separated from the inner bag 20 and can be stably packed.

FIG. 7 is a view illustrating a waistband in a backpack according to an embodiment of the present invention. In the backpack 100 according to an embodiment of the present invention, the outer envelope 10 may further include a waistband 40 extending laterally of the outer envelope 10 near the lower portion of the suspender 12.
