The structure of the mountaineering bag can be divided into three parts, namely the carrying system, the loading system and the external hanging system.
Carrying system: ensure comfort and load bearing
The carrying system of the mountaineering bag includes: double shoulder straps, waist belt
, chest strap, force adjustment belt, Carry the support mechanism and adjustment device. The biggest difference between mountaineering bags is the carrying system. The design of the carrying system of mountaineering bags with excellent performance not only considers ventilation, but also considers the ease of force transmission and the comfort and load-bearing strength of the carrying.
In the early days, the most common support mechanism of mountaineering bags was U-shaped tube or double-strip support. In order to enhance the stability of the backpack, the modified backpack adopts a font-shaped support. PERFORMICXILIE adopts an alloy tube frame support. The selection of materials is made of high-strength, high-elasticity alloy tubes, which not only reduces the weight of the support material, but also makes the force more uniform. On the shoulder fulcrum treatment, the PERFORMIC series is raised with a soft and ventilated material. A saddle is formed on the back, so as to solve the ventilation well.
The adjustment mechanism of the mountaineering bag can be divided into an upward adjustment and a downward adjustment. The upward adjustment generally has an adjustment point at the root of the shoulder strap, and the downward adjustment is to install an adjustment device in the middle of the belt. Although these two types of adjustment can also be adjusted Adjust the back size according to the height of the bearer, but subject to certain restrictions, the PERFOMIC series adopts the stepless adjustment of shoulder and waist connection, which completely overcomes the limitations of the first two adjustment methods, and the bearer can arbitrarily adjust to the best position according to personal needs.
The shoulder straps of the professional mountaineering bag are all attached with a stress belt, and there are one or two sets of adjustment fulcrums, which are used to adjust the distance between the shoulders of the backpack and bear the gravity of the upper part of the backpack to evenly act on the waist . The chest strap adjusts the opening of the double shoulder straps, which enhances the stability of the pack and facilitates breathing.
Loading system: convenient for sub-packing
The loading system of the mountaineering bag refers to the part of the backpack that loads the items. The design generally consists of a main bag, a top bag and a side bag. The main bag design adopts the upper and lower layered type, that is, there is an opening at the upper end and the lower end, and a movable compartment in the middle can be connected or disconnected.
The newly launched four-door backpack, in addition to the upper and lower openings, has newly added openings on both sides, so that it is more convenient to take and place items (due to the addition of zipper openings in this type of backpack, the rain resistance of the backpack has decreased , should be equipped with a rain cover). Some backpacks are designed with side bags, which can also be called ear bags??like two ears on both sides of the backpack. For the design of the side bag for the plug-in side, the side bag can be installed at any time when in use, and can be removed when not in use or when the plug-in is used.
Plug-in system: Freely fix external objects
A professional mountaineering bag, the plug-in system is essential. The external hanging of the backpack can be divided into top hanging, side hanging, back hanging, bottom hanging, etc., usually using point fixing or strip fixing. The point-mounted type generally has two or four corresponding hanging points. Two-point or four-point binding is adopted for fixing in use. The strip-mounted type is usually two rows of external hanging strips on the front of the backpack, each with several fixed points. The fixed items are more random and less affected by the shape.
Although all mountaineering bags are designed with external attachment points, most of them are not equipped with external attachment straps. Users can use soft nylon ropes to fix them, or go to a mountaineering equipment franchise store to purchase a standard (a standard design form) plug-in attachment. bring.
