Description

Backpack capable of adjusting the length of backplate}

The present invention relates to a backpack that can adjust the length of the back plate, and more particularly to a backpack that can accurately adjust the length of the back plate to fit the body shape while maintaining the overall appearance of the backpack body.

Recently, as leisure time increases, many people use this leisure time and actively use it in various fields such as tourism, travel or leisure sports. Among these leisure sports, mountain climbing which can be enjoyed at low cost is widely known to increase the mental and physical limits of people, and thus the mountain climbing population is increasing rapidly in Korea.

Climbing backpacks worn on the back at the time of climbing is one of the most basic and very important essential equipment of the climbing equipment, and according to the weight or type of baggage or the conditions of the climbing destination and the period of the climbing, suitable climbing backpack should be prepared.

In particular, it is very important to choose a backpack size that suits one's body type, because climbing backpacks are the heaviest among climbing equipment and must be worn while worn on the back for a long time. This is because if you buy a backpack that does not fit your body type, you may experience pain or shoulder pain while using the backpack, or even after hours of use, which may cause stress or muscle pain.

In general, the size of the backpack to fit the user's body shape is determined not by the size of the height, but by the upper body length, that is, the torso length.

Here, the torso length refers to the length from the top of the pelvis to the seventh cervical spine (the point where the spine meets the cervical spine), as shown in FIG. 1.

This is because 80-90% of the weight of the backpack is responsible for the waist when the backpack is worn, so the backpack's back dimension must be exactly the wearer's torso length in order for the weight of the backpack to properly support the waist.

Backpack manufacturers generally do not manufacture and sell back dimensions for each user, but pre-build and sell them according to several standard sizes. However, even in the same size, it is very difficult to purchase and wear a backpack that fits the shape of an individual user because each person has a different body shape and physique.

In particular, climbing backpacks can be used for more than 10 years once purchased. Even if you purchase a backpack that fits your body type, the size does not fit because it changes frequently over time. Will occur.

Of course, it is possible to adjust the length of the backpack to be worn on the back by adjusting the length of the suspenders when wearing the backpack, but this is not just adjusting the back dimensions of the backpack itself, but simply adjusting the top and bottom height of the backpack located on the wearer's back. Even if the height of the backpack is controlled by adjusting the length, the weight of the backpack cannot be properly supported by the waist. Also, if the length of the suspender is too short, the backpack is too close to the back, which causes pain in the shoulders and back. On the contrary, if the length of the suspender is too long, the back and the backpack are too far apart so that the weight of the backpack is not properly distributed to the body.

In consideration of this point, in recent years, a large scale backpack has been developed to allow a user to adjust the size of the backpack according to the user's body shape.

As shown in Fig. 2, the German Patent Publication No. 19605270 (published on Aug. 22, 1996) includes a ladder installed at a predetermined height on the back of the backpack 5 and the connection tape 10 connected to the suspenders 2,3. By using the fixing tape 6 in the form, a plurality of passages 8 formed at regular intervals above and below the fixing tape 6 pass through the passages 8 having a predetermined height suitable for the user's body shape. The technique of adjusting the length of the back plate is disclosed.

However, the prior art disclosed in the above publication has a structure in which the connecting tape must be inserted across a plurality of passages of the ladder-shaped fixing tape in order to adjust the backpack backboard length. There is a problem in that the passages are not formed continuously but formed at regular intervals, so that there is a limit to adjust the exact backplate length.

In particular, there is a space on the rear of the backpack, with the connecting tape providing the back length control, which is limited in space for additional ventilation at the rear of the backpack. There is a problem that the appearance of the backpack body is not maintained because it is additionally configured on the rear of the backpack of the configuration such as fixing tape.

Accordingly, the present invention has been made in view of the above, and an object of the present invention is to provide a backpack capable of easily and accurately adjusting the length of a backpack backboard to fit a user's body while maintaining the appearance of the backpack body when the backpack is worn.
