A mountaineering bag, as the name suggests, is a backpack used by climbers to carry supplies and equipment. Mountaineering backpack is an important piece of equipment for carrying various travel items and is essential for travel. Next, I will introduce the various functions of the outdoor mountaineering backpack.
1. The structure and function of a mountaineering bag
The structure of a mountaineering bag can be summarized into three parts: the carrying system, the loading system and the external plug-in system.
1.1 Backpack System
1.1.1 Design Principle of Backpack System
Backpack design comes from ergonomics. The human spine is composed of 26 vertebrae. We are divided into 5 areas. From top to bottom, 1-7 blocks are the first area; 8-19 are the second area; 20-24 are the third area; 25 blocks are the fourth area; 26 blocks are the fifth area.
The spine has the following four main functions:
Support the head and trunk;
Protect the interior of the spine from injury;
Support Back muscles;
Allow the head and trunk to move freely.
Therefore, the back design of the backpack must completely conform to the shape of the human spine, so as to reduce the discomfort caused by the backpack to the human body, not hinder the activities of the head and trunk, and make the gravity of the backpack better The ground is scattered all over the back. Likewise, the distribution of muscles on the back also has a certain shape. Therefore, the backpack design must conform to the shape of human muscles. By making the materials of the backpack system conform to the shape of the muscles, we can distribute the force on the entire back instead of concentrating on a certain part of the muscles. This approach also reduces muscle fatigue and makes the backpack more stable on the body.
Human clavicle is usually protruding, so the shoulder straps on the back of the backpack must be designed according to the shape of the clavicle. The back shoulder straps of the backpack must be designed according to the shoulder bones, and fully consider the freedom of movement of the shoulder bones. The waistband design of the backpack fully takes into account the shape of the human body's hip bones, and increases the stability of the backpack, allowing it to move with the movement of the hip bones.
The dominant idea of ??the backpack's carrying system is to distribute the weight throughout the entire back rather than concentrating it in one place. It is based on this idea that the design of weight transfer is formed. The hip belt of the backpack is designed with a conical upward slope. This design is more in line with the waist curve of the human body and can distribute the force to various parts of the waist. The force on the shoulders of the shoulder straps starts from the bottom of the backpack. Through this design, we distribute the weight throughout the back.
We often see the idea of ??going camping with a large bag on your back. In fact, the accurate term should be to go camping with a large bag on your back, because when a person carries a backpack, the stress point is on the waist, and the shoulders only assist in receiving the force. and control balance. If you only use your shoulders to bear the weight, you will definitely have sore shoulders and back pain at the end of the day. It is not difficult to understand that the gravity of the backpack transmits power from shoulders to waist and from waist to legs in multiple links, which increases physical consumption. The center of gravity is placed on the waist, which reduces the transmission link of load-bearing force and reduces unnecessary physical exertion. The intelligent carrying system provides the most scientific and simple power transmission, good ventilation, and ensures the perfect combination of the backpack and the human body. It is natural and comfortable to wear it.
1.1.2 Structure of the carrying system
The function of the carrying system is to ensure load-bearing and carrying comfort. The structure includes five strap functions (shoulder straps, force adjustment straps, chest Belts, hip belts, waist-adjusting straps), support devices, ventilation devices and adjustment devices. The carrying system is the core of the technological content of a backpack. The biggest difference in the performance of a backpack lies in the carrying system. The carrying system of a mountaineering bag with good performance is not only designed to consider ventilation, but also facilitates the transmission of gravity, has strong load-bearing capacity and is comfortable.
Five-belt function:
The five-belt function of the backpack system is to ensure the reliable combination of the backpack and the human body, ensure correct force transmission and assist in load-bearing. Its materials, technology, and design directly affect the comfort of carrying it.
In order to ensure shoulder comfort, the manufacturer invented the "S" shoulder strap, so that the shoulder strap can go around the neck without getting stuck in the shoulder socket. The material is often molded at high temperature to form a multi-layer bubble film and an elastic Lycra outer layer, making it The shoulder pads are extremely comfortable; the shoulder straps are connected through the whole body, which not only ensures the adjustment of the center of gravity of the backpack, but also meets the load-bearing requirements; the chest strap is a small part of the carrying system, but it is not an insignificant part. The main function of the chest strap is Adjust the distance between the shoulder straps to enhance the stability of the backpack and facilitate breathing; the waist belt is the load-bearing part of the backpack, usually composed of a lumbar pad and a waist belt. It adopts a movable design. The belt is fixed in the lumbar pad at the bottom of the backpack with nylon tape. Open the lumbar pad to Fine-tune up and down to find the best combination point; backpack waist bottom adjustment straps are divided into single straps and double straps. Professional backpacks are all double strap adjustments and cross-strength, ensuring that the bottom of the backpack and the lumbar support and waist reliable combination.
Support device:
The perfect backpack design comes from improvement and innovation. In the early days, U-shaped tubes and double aluminum bars were common. The improved backpack uses a glyph-shaped aluminum sheet and template support. , although it enhances stability, it also increases the weight of the backpack. In order to improve the carrying performance, at the end of the 20th century, backpack manufacturers invented the "TCS" carrying system. This alloy tube frame support structure is prefabricated with high-strength and high-elastic titanium alloy tubes, which greatly reduces the weight of the material. It also has higher force strength and more balanced weight distribution. Its large-capacity backpack is equipped with lumbar supports to make the load-bearing force more integrated. In order to solve the problem of looking up while traveling, the system is designed with a recessed headrest. The user-friendly design of the TCS backpack system has ranked first in the European mountaineering bag backpack performance evaluation for six consecutive years, and is known as the "intelligent backpack system".
Ventilation device:
Good ventilation is an important indicator of carrying comfort. In order to solve the problem of ventilation of the carrying system, manufacturers usually use soft ventilation materials to bulge the shoulders and design them into shaped cushions. , an adjustable breathable cushion is installed at the lumbar fulcrum to form a saddle in the carrying position, thereby improving ventilation. In order to adapt to different body shapes and personalities of the carriers, the lumbar support point cushion can be opened and a pad is added inside, which can solve the problem of weak connection between the stress point and the lumbar support point for those with thin buttocks.
Adjustment device:
The backpack adjustment device is developed on the basis of the fixed device. The fixed device can only adapt to a specific height and is very inconvenient to use, so the manufacturer developed an adjustable Adjustable carry. Adjustable backpacks are divided into upward-adjustable and downward-adjustable backpacks: the upward-adjustable backpack generally has a step adjustment at the root of the shoulder strap, while the downward-adjustable backpack has an adjustment device installed in the middle of the waistband. Although these two types of adjustment methods can adjust the distance of the back according to the shape of the wearer, But subject to certain restrictions. In order to solve this contradiction, the manufacturer developed the infinitely adjustable waist-shoulder connection, which completely overcomes the limitations of the first two adjustment methods. The wearer can adjust it to the appropriate position according to personal needs to find the best feeling.
1.2 Mountaineering bag loading system
1.2.1 Design principle of the loading system
The function of the loading system is to load items, but whether the design is scientific or not also directly affects comfort sex and force transmission. For example, the double V-shaped design concept of the backpack draws on the force principles of Nepali backpacks and Portuguese wine barrels. The self-carrying bracket is designed into a V-shape with a large top and a small bottom. The shape of the main bag of the backpack is also designed to be large. The lower tapered shape shows that the load-bearing method of this design is scientific. Aren’t the familiar backpacks used in mountainous areas in the south also large at the top and small at the bottom? In fact, this is the crystallization of human wisdom in carrying heavy objects. The design of hidden side bags, inner and outer top bags, cosmetic bags, and additional bags greatly facilitates users.
1.2.2 Structure of the loading system
The backpack loading system refers to the part of the mountaineering bag that carries items. The structure is not too complicated and usually consists of a main bag, a top bag, a side bag, and an attachment. Bags, etc. The main bag mostly adopts the upper and lower layered type, that is, there is an opening at the upper end and the middle, and a movable partition in the middle, which can be connected or disconnected. Its advantage is that the user can separate items according to needs, and can take out the upper and lower parts. The backpack top bag is also called a head bag. It is located on the top of the backpack. It has a single bag structure or a double bag structure. It is very convenient to carry some small items. Side bags are also called ear bags, which look like two ears on both sides of the backpack. For the convenience of external attachment, some bags do not have side bags, and some use movable side bags, which need to be installed at any time and can be removed when using external attachment.
An accessory bag refers to a small bag attached to the outside of the main bag, attached to the front or side of the backpack, for the purpose of conveniently packing items. Some accessory bags can be removed and used as a small backpack alone.
