The present invention relates to a bag.
In general, bags are convenient to carry because they can be slung on the shoulders while storing necessary items, and they can be used for storing and transporting items.
These bags are one of the basic yet very important pieces of equipment used to transport items when a user stays outdoors, such as hiking or fishing, and are generally referred to as backpacks.
Users need to prepare bags suitable for the weight and type of items, the conditions of the travel destination, and the duration of the travel.
This is because the degree to which the weight of the items accommodated in a bag is transmitted to the body varies and the wearing sensation is significantly different depending on the structure of the bag, so the fatigue felt by the human body when wearing the bag is significantly different.

A wing portion 413B may have a shape in which a part of a concentric circle having a larger diameter than the diameter of the central portion 413A is sectioned.
A first body coupling portion 420 may be coupled to a back plate portion 110 of a bag body 100. A first body coupling portion 420 may be coupled to a backrest coupling portion 410 and may include a plurality of coupling areas provided at different heights.
Hereinafter, a first body coupling portion 420 is described in more detail.
A first body coupling portion 420 may include a first base portion 421, a rotation limiting portion 422, an elastic member 423, a protruding place-in/place-out plate 424, a spacing plate 425, and a second base portion 426.
A first base portion 421 may be provided inside a storage space of a bag body 100. A first base portion 421 may be provided with a plurality of protrusions that allow for screw coupling with a second base portion 426. In the present embodiment, it has been described as an example that the first base portion 421 and the second base portion 426 are screwed together, but this is not limited thereto, and the first base portion 421 and the second base portion 426 may be coupled through various methods.
In addition, a first base portion 421 may be divided into a plurality of areas where a rotation limiting portion 422 is disposed by the protrusions. Here, the areas where the rotation limiter 422 is disposed may be arranged side by side in one direction, for example, a direction perpendicular to the ground.
A first base portion 421 may be coupled to a second base portion 426 to provide a space in which a rotation limiting portion 422 and an elastic member 423 may be accommodated.
A rotation limiting portion 422 may be provided inside a storage space of a bag body 100. A plurality of rotation limiting portions 422 may be provided. A rotation limiting portion 422 may have a plate shape extending in a direction perpendicular to the direction in which the areas where the rotation limiting portion 422 of the first base portion 421 is disposed are arranged. The length of a rotation limiting portion 422 may be longer than the length in a direction perpendicular to the direction in which the areas where the rotation limiting portion 422 of the first base portion 421 is disposed are arranged. In other words, both ends of a rotation limiting portion 422 may be exposed to a storage space through a space between the protrusions of a first base portion 421. In addition, a rotation limiting portion 422 may have a shape in which both ends are bent in the direction of a first base portion 421.
A rotation limiting portion 422 may include a plurality of protrusions 422A, 422B provided in a flat area. For example, the protrusions 422A, 422B may include a circular first protrusion 422A and second protrusions 422B provided on both sides of the first protrusion 422A. The second protrusions 422B may a shape in which a part of a concentric circle having a larger diameter than the diameter of the first protrusion 422A is sectioned. Here, the protruding height of the first protrusion 422A may be smaller than the protruding height of the second protrusions 422B. In addition, the arc length of the sectioned area other than the second protrusions 422B of the rotation limiting portion 422 may be larger than the arc length of a corresponding wing portion 413B of the rotational coupling body 413. Therefore, the rotational coupling body 413 may rotate within the range of the sectioned area between the second protrusions 422B. That is, accordingly, the second protrusions 422B may limit the rotation range of the rotational coupling body 413.
An elastic member 423 may be provided between a first base portion 421 and each rotation limiting portion 422. By an elastic member 423, a first protrusion 422A of a rotation limiting portion 422 may apply pressure to a central portion 413A of a rotational coupling body 413.
In addition, an elastic member 423 may return a rotation limiting portion 422 to its original position even when the position of the rotation limiting portion 422 changes.
A protrusion place-in/place-out plate 424 may be provided inside a storage space of a bag body 100. A protrusion place-in/place-out plate 424 may have open areas 424A, 424B corresponding to protrusions 422A, 422B of a rotation limiting portion 422. In other words, a first protrusion 422A and second protrusions 422B of a rotation limiting portion 422 may be placed in and placed out through the open areas 424A, 424B. To this end, the thickness of a protrusion place-in/place-out plate 424 may be smaller than the protruding height of a first protrusion 422A and second protrusions 422B.
A spacing plate 425 may be provided inside a storage space of a bag main body 100. A spacing plate 425 may provide a plurality of open rotation spaces 425A so that a rotational coupling body 413 may rotate. A spacing plate 425 may space apart a protrusion place-in/place-out plate 424 and a second base portion 426. The thickness of a spacing plate 425 may be greater than or equal to the thickness of a rotational coupling body 413.
In addition, a spacing plate 425 may be provided in a single number or a plural number, and the number may be selected as needed. When a plurality of spacing plates 425 are provided, the sum of the thicknesses of the plurality of spacing plates 425 may be greater than or equal to the thickness of a rotational coupling body 413.
A second base portion 426 may be provided outside a storage space of a bag body 100. A second base portion 426 may include a plurality of insertion areas 426A open in a shape corresponding to a rotational coupling body 413. The insertion area 426A may correspond to a coupling area of a first body coupling portion 420. In addition, a second base portion 426 may have a shape corresponding to a first base portion 421 and may be screwed to the first base portion 421.
A second coupling portion 500 may couple the back place portion 110 of a bag main body 100 and a waist belt portion 300. In addition, even if shaking of a user's body occurs when the user moves while wearing the bag, a second coupling portion 500 may maintain the posture of the bag constant.
A second coupling portion 500 may include: a waist belt coupling portion 510 coupled to a part of a waist belt portion 300; and a second body coupling portion 520 coupled to a part of a back plate portion 110. Here, the waist belt coupling portion 510 may be configured substantially the same as the backrest coupling portion 410 of the first coupling portion 400, and the second body coupling portion 520 may be configured the same as the first coupling portion 400 of the first body coupling portion 420. However, the second body coupling portion 520 may have a smaller coupling area compared to the first body coupling portion 420.
The waist belt coupling portion 510 may be configured substantially the same as the backrest coupling portion 410. That is, similar to the backrest coupling portion 410, the waist belt coupling portion 510 may include a first fixture 411 provided in the user direction of the waist belt portion 300; a second fixture 412 provided in the direction of the backrest portion 210 of the waist belt portion 300; and a rotational coupling body 413.
Hereinafter, a method of coupling a backrest coupling portion 410 and a first body coupling portion 420 will be described.
First, as shown in
Then, as shown in
When the rotational coupling body 413 is inserted into the first body coupling portion 420, the rotation limiting portion 422 may be pressurized to move in the direction of the backrest 210. That is, the first protrusion 422A and the second protrusion 422B of the rotation limiting portion 422 may enter into the open areas 424A, 424B of the protrusion place-in/place-out plate 424, so that the rotational coupling body 413 may rotate inside the first body coupling portion 420.
After a rotational coupling body 413 is inserted into a first body coupling portion 420, the rotational coupling body 413 may rotate within a rotation space 425A. When the rotational coupling body 413 rotates and an area other than a second protrusion 422B of a rotation limiting portion 422 corresponds to a wing portion 413B of the rotational coupling body 413, a first protrusion 422A and a second protrusion 422B of the rotation limiting portion 422 may protrude out of the open areas 424A, 424B of the protrusion place-in/place-out plate 424 by an elastic member 423. When the first protrusion 422A and the second protrusion 422B protrude out of the open areas 424A, 424B of the protrusion place-in/place-out plate 424, the first protrusion 422A and the second protrusion 422B may limit the rotation of the rotational coupling body 413, and as shown in
As described above, a user may insert a rotational coupling body 413 into the insertion areas 426A, 426B at various positions. Therefore, a user may adjust the height of a shoulder slinging portion 200 to a height suitable for their own body. By adjusting the height of the shoulder slinging portion 200, the user may adjust the wearing sensation of the bag to be suitable for their own body.
Hereinafter, a method of separating a backrest coupling portion 410 and a first body coupling portion 420 is described.
First, in a state in which a rotational coupling body 413 of a backrest coupling portion 410 is coupled, a user moves a rotation limiting portion 422 inside the bag body 100 in the opposite direction of the back plate portion 110.
When the rotation limiting portion 422 moves in the opposite direction of the back plate portion 110, a first protrusion 422A and a second protrusion 422B may move into the open areas 424A, 424B of the protrusion place-in/place-out plate 424.
When the first protrusion 422A and the second protrusion 422B move into the open areas 424A, 424B of the protrusion place-in/place-out plate 424, the rotational coupling body 413 may be in a rotatable state.
After this, when the rotational coupling body 413 may be rotated so that the rotational coupling body 413 is disposed to correspond to the shape of the insertion areas 426A, 426B of the second base portion 426, the user may separate the backrest coupling portion 410 and the first body coupling portion 420.
When the backrest coupling portion 410 and the first body coupling portion 420 are separated, the bag body 100 and the shoulder slinging portion 200 may be separated.
Meanwhile, the arc length of the sectioned area other than a second protrusion 422B of the rotation limiting portion 422 may be larger than the arc length of a corresponding wing portion 413B of the rotational coupling body 413. Therefore, as shown in
As the rotational coupling body 413 may rotate in a predetermined angle range, as shown in
As described above, as the rotational coupling body 413 of the first coupling portion 400 and the second coupling portion 500 is rotatable within a certain angle range, even if shaking of a user's body occurs when the user moves while wearing the bag, the bag body 100 may maintain a state of being perpendicular to the ground.
Accordingly, even when a user of the bag stores a heavy item in the bag body 100 and wears the bag, a less burden may be placed on the user's body.
Hereinafter, another embodiment will be described, focusing on differences from the previously described embodiment.
In the first body coupling portion 420 of the first coupling portion 400 according to one embodiment, the first base portion 421 could be divided into a plurality of areas where the rotation limiting portion 422 may be disposed on a side surface. In addition, the rotation limiting portion 422 could have a plate shape extending in a direction perpendicular to the direction in which the areas in which the rotation limiting portion 422 is disposed are arranged.
In contrast, in a first body coupling portion 420 of a first coupling portion 400 according to another embodiment, a first base portion 421 may not be provided with a plurality of areas on a side surface.
In other words, since the rotation limiting portion 422 according to another embodiment may not have a plate shape extending in the vertical direction, as shown in
A first coupling portion 400 according to another embodiment may be provided with a rear surface in a sealed form, but a protrusion adjusting portion 422C that is further provided may penetrate the first coupling portion 400 according to another embodiment.
A protrusion adjusting portion 422C may be disposed to penetrate a first base portion 421 and a first protrusion 422A, and may be mechanically connected to protrusions 422A, 422B.
A protrusion adjusting portion 422C may be operated according to a change of position, and when the position of the protrusion adjusting portion 422C changes, movement may occur together with the mechanically connected protrusions 422A, 422B. Referring to
According to
In a situation in which a protrusion adjusting portion 422C is not operated, a first protrusion 422A may protrude while being penetrated by the protrusion adjusting portion 422C, and a second protrusion 422B may also protrude. There may be a difference in the relative protruding height of a first protrusion 422A and a protrusion adjusting portion 422C, but in a situation in which a protrusion adjusting portion 422C is not operated, the protruding height of a first protrusion 422A may be higher than that of a protrusion adjusting portion 422C.
Referring to
In a situation in which a protrusion adjusting portion 422C is operated, as the protruding height of protrusions 422A, 422B is lowered, the movement of the rotational coupling body 413, which limited the rotation range of the protrusions 422A, 422B, may become free. Therefore, the rotational coupling body 413 may freely rotate to be disposed corresponding to the shape of an insertion area 426A to be separated from the inside of a first body coupling portion 420.
In other words, in the first body coupling portion 420 according to one embodiment, the rotation limiting portion 422 could be moved in the opposite direction of the back plate 110 to move the first protrusion 422A and the second protrusion 422B into the open areas 424A, 424B, so that the rotational coupling body 413 could be in a rotatable state. The rotation limiting portion 422 was exposed to the inside of the bag body, and so it could be operated by opening the bag or through a separate device connected to the rotation limiting portion 422.
On the other hand, a first body coupling portion 420 according to another embodiment is simple because it may simultaneously move a plurality of first protrusions 422A and second protrusions 422B through movement of a protrusion adjusting portion 422C, and the rotational coupling body 413 may be separated at the same time.
By operating a protrusion adjusting portion 422C, a plurality of first protrusions 422A and second protrusions 422B may simultaneously move to the inside, but as a plurality of protrusion adjusting portions 422C are prepared or a single protrusion adjusting portion 422C is disposed depending on the design, each of the first protrusion 422A and the second protrusion 422B may independently move to the inside.
The present invention is not limited to the above-described embodiments and may, of course, include a combination of at least two or more of the above embodiments or a combination of at least one of the above embodiments and a known technology as a new embodiment.
Although the present invention has been described in detail through specific embodiments, these are for specifically explaining the present invention, and the present invention is not limited thereto, and it is clear that modifications and improvements thereof are possible by those skilled in the art within the technical spirit of the present invention.
All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
