Description

Adjustable shoulder strap

The present invention relates to a variable length shoulder strap, and more specifically, by configuring the length of the shoulder strap of a backpack or carrying bag to be variable, allowing the user to easily wear the backpack or carrying bag, etc., and at the same time, after wearing it. The backpack or carrying bag is designed to adhere closely to the user's back so that it can be worn stably.

In particular, the present invention does not allow the user to adjust the shoulder straps one by one after wearing a backpack or carrying bag, but rather allows the length to be adjusted with just one action, such as attaching or detaching a buckle, as in the one-touch method. It's about a variable shoulder strap.

In general, a backpack is a type of bag that a user (wearer) carries on his or her back, and is comprised of a main body for storing items and shoulder straps on both sides of the main body.

The following prior art document, Republic of Korea Patent Publication No. 10-1293538, 'Backpack with Gel Pad Built-in Shoulder Strap', represents a general example of such a backpack.

Meanwhile, these shoulder straps are used by the user by adjusting them to fit their body, but the following problems may occur.

First, when the length of the shoulder straps is adjusted to be long so that the user can easily wear the backpack, there is a problem in that the backpack does not adhere closely to the user's back after wearing.

In this way, if the backpack does not adhere closely to the user's back, the backpack's own weight moves down after wearing, which causes the center of gravity of the backpack to move downward, causing strain on the user's waist when worn for a long time, etc. There is a problem that it has a negative effect on the user's body.

Additionally, when a user moves while carrying a backpack, such as walking, the bag shakes behind the user's back, and this movement of the backpack has an even worse effect on the user's body.

This problem is even more so when items of considerable weight, such as a hiking backpack, are stored.

Second, in order to solve the previous problem, if the length of the shoulder straps is shortened, it may be difficult for the user to wear the backpack, and may even become impossible to wear.

Third, after the user puts on the backpack, there is also a way to adjust the length of the shoulder straps to fit the backpack closely. However, in this case, the shoulder straps are unfastened from the clips connected in an 'S' or 'U' shape to prevent the shoulder straps from coming loose. Since you have to go through a re-tightening process after adjusting the length, there is a problem that considerable inconvenience occurs in adjusting the length.

In particular, in cases where a significant amount of weight is stored, such as a mountaineering backpack as discussed above, it may be impossible to adjust the shoulder straps due to the weight of the bag.
