Outdoor backpack function description

Backpack is one of the most important and basic outdoor equipment. In outdoor activities, usually need to carry a large number of items, such as tents, sleeping bags, clothes, food, etc., then a special backpack can play a big role.

Early backpack negative design is not reasonable, the weight focus on the shoulders, after long-term use can cause shoulder, waist pain fatigue, and with the continuous improvement of design level, now professional outdoor backpack can save the trouble of hand, and can keep the stability of walking, more important is the right backpack can maximize to reduce the traveler in the case of weight body fatigue.

These functions mainly depend on its three major systems, --, namely carrying system, loading system and plug-in system.

 Carrying system The function of the bearing system is to ensure the comfort of load and bearing, the structure includes five belts (shoulder belt, force adjustment belt, chest belt, belt, waist bottom adjustment belt), support device, ventilation device and adjustment device. The bearing system is the core of the technology content of the backpack. The biggest difference in the performance of a backpack is also in the carrying system. The carrying system of the mountaineering bag with good performance not only considers ventilation, but also facilitates gravity transmission, strong bearing force and comfort.
The five belt function of the five belt carrying system is to ensure the reliable combination of the backpack and the human body, to ensure the correct force transmission and assist load bearing. Its material, technology and design mode directly affect the comfort of bearing.

Belt: the belt is the load-bearing part of the backpack, usually composed of the waist cushion and belt, using the activity design, the belt with nylon paste fixed in the bottom of the backpack cushion, open the waist cushion can fine-tune up and down, in order to find out the best combination point;

Shoulder strap: in order to ensure the comfort of the shoulder, the manufacturer invented the "S" shoulder strap, so that the shoulder strap can bypass the neck and does not card the shoulder socket, the material is often selected by high temperature molding to form multi-layer bubble film with elastic fabric outer layer, so that the shoulder pad is extremely comfortable;

Force adjustment belt: the shoulder force belt adopts the whole body connection, which not only ensures the adjustment of the bearing center of gravity, but also meets the requirements of the bearing force;

Waist bottom adjustment belt: backpack waist bottom adjustment belt and divided into single belt, double belt two kinds, professional backpack is double belt adjustment, cross force, to ensure the reliable combination of the bottom of the waist and the backpack.

Chest band: the chest band is a small part of the carrying system, but it is not an insignificant part, the main function of the chest band is to adjust the shoulder band opening distance, enhance the stability of the backpack and facilitate breathing;

Support device this alloy pipe frame type support structure, choose high strength, high elastic titanium alloy tube prefabricated, greatly reducing the weight of the material, and make its stress strength is higher, the dispersed weight is more balanced, its large volume backpack added waist support, so that the load-bearing force is more integrated. In order to solve the problem of the backpack looking backward when looking up, the depression head leaning function is added in the design, and this carrying system has also gained the reputation of "intelligent carrying system".

Good ventilation of ventilation devices is an important indicator of carrying comfort. In order to solve the ventilation of the carrying system, the manufacturer usually uses soft ventilation material uplift, and the shoulders are designed into a shape cushion, and the waist fulcrum forms a saddle, thus enhancing ventilation. To adapt to different burden body type personality, its waist fulcrum cushion can be opened, add a liner inside, can solve the buttocks wasting person force point and waist fulcrum combination is not strong contradiction.
actuating device

The load adjustment device is developed on the basis of fixed device. The fixtures can only fit to a specific height and are inconvenient to use, so the manufacturer developed adjustable loading. Adjustable back burden is divided into up and down adjustment: up adjustment generally sets ladder adjustment at the root of the shoulder belt, and down adjustment is to install adjustment device in the middle of the belt. Although these two types of adjustment methods can adjust the back distance according to the body of the bearer, they are limited to a certain extent. In order to solve this contradiction, the manufacturer has developed the infinite adjustment type, which completely overcomes the limitations of the first two adjustment methods. The bearer can adjust to the appropriate position according to the individual needs, so as to find out the best feeling.

Loading system backpack loading system refers to the part of the mountaineering bag loading items, the structure is not too complex, usually composed of the main bag, top bag, side bag, attached bag and so on.

The main bag is mostly layered at the upper and lower levels, that is, the upper end and the middle part of the middle layer, which can be connected or disconnected. Its advantage is that the user can divide the items according to the needs, and the upper and lower can be taken out. The backpack top bag is also called the head bag, located at the top of the backpack, it has a single bag structure and a double bag structure, containing some small items, it is very convenient to take. Side bag is also called ear bag, like two ears on both sides of the backpack, for the convenience of external hanging, some bags do not set side bag, some use the active side bag design, need to be installed at any time, using the external hanging can be removed. Attached bag refers to the small bag attached outside the main bag, attached to the front or side of the backpack, for the purpose of easy packaging items, some attached bags can be used separately as a small backpack.

The system is to increase the number of items carried to facilitate irregular items. A professional mountaineering bag, the plug-in system is essential. Backpack external hanging system can be divided into top hanging, side hanging, back hanging, bottom hanging, etc., usually using the point fixed or fixed bar. Point hanging generally set a group or two groups of corresponding hanging points, using four points binding fixed. Bar hanging is usually in the front of the backpack, each with a number of fixed points, its fixed items are more casual, less affected by the shape.

Professional backpack design has its unique features, including long and short ice picks; the pocket of side hanging items; a small hanging bag for water bottles; strong crampon fixed structure and high strength puncture resistant synthetic leather pads. This rational design from practice ensures the perfection of the backpack on the load. Reasonable use of the plug-in system, can double your backpack capacity.
