Description

Bag suspenders with adjustable strap width{SHOULDER STRAP}

The present invention relates to a suspending strap for a bag capable of adjusting the width of the strap, and an expansion portion that can be folded or unfolded is connected to a pocket provided in the strap, so that the area where the strap is supported using the expansion portion when carrying a heavy bag A strap for a bag that allows you to wear the bag more easily by distributing the weight of the bag by distributing the weight of the bag and providing posture correction effect by extending the shoulder while the expansion part is aligned with the curvature of the upper body. It is about.

Bags can be classified into various types depending on how they are worn or their main purpose of use. Most bags (backpacks, duffel bags, double bags, backpacks, etc.) excluding clutch bags and handbags are straps that can be worn around the shoulder. Available as standard or optional.

Among the bags equipped with suspenders, the bulky bag has a wider width of the left and right side of the strap than that of a general small bag, so that the weight applied to the shoulder when carrying a large-capacity item is dispersed.

However, no matter how wide the left and right widths of the straps for large bags are limited by the average shoulder width due to the body structure, most of the straps are manufactured to have the same width.

However, when the weight of the bag increases, the weight is not properly distributed with only the conventional suspenders, which puts a burden on the shoulder and causes pain.

For this reason, in some large bags, a chest belt is applied that connects and collects the straps of the chest or stomach area in a belt type, but such a chest belt only helps to support the heavy bag. There is no weight distribution effect applied to the suspenders, so there is a limit to improving the fit of a heavy bag.

As a prior art for solving this problem, there is a registered utility model No. 20-0333036.

In the above design, a suspenders of a three-dimensional structure with a wide wow width are connected to the three-dimensional suspenders at the back of the bag, so that the left and right suspenders are gathered into the chest area so that the suspenders are in close contact with the chest, thereby enhancing the fit.

However, the extension of the suspenders of the design is connected in a protruding form from one end of the strap, so that the extension is always exposed even when the extension is not required, so when the weight of the bag is light, the extension rather impairs the fit and makes it difficult to use. There is a problem to give.

Accordingly, the present invention was devised to solve the above problems,

A relatively light bag can be worn in the form of a general strap, and when the bag is heavy, the width of the left and right sides of the strap is increased to increase the area supported by the body, while the extension is aligned with the curvature of the upper body to induce three-dimensional weight distribution. It is an object of the present invention to provide a strap for a bag capable of adjusting the width and width of the strap to allow the bag to be worn more conveniently and comfortably by adjusting the left and right widths of the bag as necessary.

In order to achieve the above object, the suspending strap for a bag according to the present invention,

In the bag strap,

A strap having a pocket formed by having one end opened in a section of a predetermined length at a position spaced apart from the sewing unit by a predetermined distance from the sewing unit and connected to the bag at both ends;

And an extension part which is connected to be folded or unfolded in and out of the pocket at one end of the opening of the pocket and extends to one side of the strap.

And in the suspenders for bags according to the present invention,

The strap is connected to the back of the bag in a pair of left and right so that the extension part is connected to the inner end of each strap,

It characterized in that it comprises a tightening connecting means for fixing by connecting the two extensions to each other.

Also in the suspenders for bags according to the present invention,

And an expansion preventing means for preventing the expansion portion accommodated in the pocket from spreading out of the pocket.

Suspenders for bags according to the present invention,

A foldable extension is connected to the pocket of the strap that spans the shoulder, so when the weight of the bag is light, the extension can be folded and used.When the weight of the bag is heavy, the extension extends to increase the area supported by the body, while the extension of the upper body By inducing the weight distribution of the bag three-dimensionally according to the bend, it can be easily and conveniently worn and used while increasing the fit of the bag if necessary.

In the case of student bags or office backpacks equipped with left and right straps, when using the extension, the left and right extensions are connected and tightened, so that the extension is in close contact with the entire chest, enhancing the weight distribution effect, By preventing the narrowing of the posture, it can give a posture correction effect,

The present invention relates to a suspending strap for a bag, as shown in Figs. 1 to 5, a strap 10 that allows the bag to be largely worn on the shoulder, and an extension that can stretch the shoulder while inducing weight distribution of the bag (20), including a fastening connection means for tightening the two side extensions 20 in close contact with the chest, and an unfolding prevention means for preventing the extension 20 of the pocket 12 from being unfolded.

In this specification, for convenience of understanding, a pair of left and right straps 10 are connected to the back of the bag to represent a backpack or backpack-type bag (B) that can be worn on both shoulders, but the bag is referred to as one shoulder A configuration related to the extension part 20, which is the core of the present invention, may be applied to a duffel bag or a double bag suspending strap or a baby carrier with shoulder strap that can be worn on the bag.

Specifically, the present invention,

A strap 10 having a pocket 12 formed by opening one end in a section of a predetermined length at a position spaced apart from the sewing part 11 by a predetermined distance from the sewing part 11 and connected to the bag B and carried on the shoulder;

And an extension part 20 that is connected to be folded or unfolded in and out of the pocket 12 at one end of the opening of the pocket 12 and extends to one side of the strap 10.

The strap 10 is in the form of a shoulder strap provided in a general bag (B), and both ends are sewn and connected to the back of the bag (B), so that the length of the strap 10 can be adjusted with a length adjustment strap (13). Has been.

In particular, the strap 10 includes an elastic band (not shown) having a predetermined elasticity in the hook portion 14 excluding the length adjustment string 13, so that the hook portion 14 is unfolded and the bag (B) To be able to wear, this elastic band is also inserted into the expansion part (20).

The hook portion 14 of the strap 10 has a double-sided structure in which one end is opened while the other end is folded, and the expansion part 20 is integrally connected to the inner part 14A in close contact with the body, (20) can be folded or unfolded toward the front outside.

In addition, the strap 10 overlaps both inner and outer sides from the upper sewing part 11 to form a pocket 12 space with a sewing line 14a, and a space excluding the entrance of the pocket 12 is sewn.

The expansion part 20 is connected to be folded or unfolded in and out of the pocket 12 at one end of the opening of the pocket 12 (the inner part 14A of the strap 10), and the strap 10 To one side.

That is, when the bag (B) is light, the extension part 20 is folded into the strap 10 to wear the bag (B) in a general form, and when the bag (B) is heavy, the extension part 20 is attached to the strap ( 10) Wear the bag (B) in a form that spreads out and induces weight distribution.
