Multifunctional backpack

Abstract

The invention relates to a multifunctional knapsack system I, and belongs to the technical field of knapsacks II. According to the scheme key points and the main purpose scheme key points, a knapsack is composed of a plurality of independent knapsacks, and the original independent knapsacks are combined into one knapsack in a modularized mode. The knapsack is mainly used for personal commuting, traveling and daily life, and can be used as a main body knapsack for commuting and a schoolbag. The computer bag can be used for loading computers and tablet computers. The small bag is used for containing wallets and scattered articles at ordinary times. The traveling bag can be used during traveling. The combination of the main body bag and the knapsack can be used for mountaineering articles and can also be used for holding articles when people go far at ordinary times.

Description

1. Technical Field

[0001] The invention belongs to the technical field of backpack manufacturing, and in particular relates to a method for assembling a backpack and distributing the force of a shoulder strap. 2. Background Technology

[0002] The background technology of the present invention is some existing combined backpacks. III. Summary of the invention

[0003] 1. Purpose of the invention

[0004] The present invention can solve the overall problem of the backpack, and the combination and decomposition of the backpacks can reduce the number of backpacks, optimize the force-bearing mode of the backpack straps, make the cushion pad more compatible with the human body, and make the backpack more comfortable to use.

[0005] 2. Detailed description

[0006] The present invention is composed of a main backpack, a computer secondary bag, a commuter bag, a functional small bag, and a torpedo bag, and the whole is composed of a backpack and a carrying system. The carrying system is composed of a shoulder strap and a cushion sponge. The shoulder strap changes the original single-point force to a multi-point force mode, optimizes the force of the backpack, and solves the problem of the backpack falling. The cushion device on the back of the backpack is equipped with a cylindrical sponge that is integrated with the back curve of the human body.

[0007] The backpack consists of a main bag, which contains two torpedo bags for small sundries and some relatively scattered things. There is a rope for tying sleeping bags at the bottom of the main bag, which is used to tie sleeping bags and other items. The surface of the main bag is combined with the computer bag through a buckle belt by a ladder-shaped attachment system to increase the loading capacity of the main bag. The travel bag under the main bag uses a buckle belt and the main bag's ladder-shaped secondary bag attachment system to increase the loading capacity. The two sides are composed of a ladder-shaped secondary bag attachment system for combining 3 small bags. There is a semicircular groove on the back of the main bag to hold the belt. When using the belt, insert it into the semicircular groove and take it out when not in use.

[0008] 3. Beneficial effects

[0009] The backpack can reduce the original stress on the shoulder strap, and change the stress on the shoulder strap from single-point stress to multi-point stress.

[0010] The backpack combines the original computer bag, small bag and travel bag into one backpack system, which can be disassembled and combined according to different needs.

[0011] The cushioning pad on the back of the backpack has been changed from a fixed type to an adjustable type, and the position can be adjusted according to personal circumstances. IV. Description of the drawings

[0016] The present invention is composed of various independent backpacks, which can be used alone or as a whole. The present invention is composed of the following parts: 1. Carrying system, 2. Main backpack, 3. Computer bag, 4. Travel bag, 5. Small bag, 6. Back cushion system, 7. Waist belt. The present invention mainly combines the independent backpacks into a whole by combining various bags, thereby expanding the capacity of the backpack and reducing the number of backpacks. Back cushion system, add a sponge cylinder at the back cushion position to cushion the pressure of the back and conform to the back human curve; Carrying system, the shoulder strap is composed of a cushion layer and a shoulder strap, the shoulder strap is set to 4 points, changed from the original one point to 4 points, and 2 shoulder strap connection points are added at the bottom to disperse the force and prevent the shoulder strap from breaking at the bottom; The main bag is layered, and two torpedo bags are added to place scattered items in the backpack, which is conducive to the classification of items; Backpack sub-bags, the sub-bags are composed of 3 categories, one is a computer bag, which is a 14-inch computer handbag with a ladder-shaped sub-bag attachment system, the second is a travel bag, which is a travel bag with a ladder-shaped sub-bag attachment system, and the third is a small bag composed of an ordinary small bag, with a ladder-shaped sub-bag attachment system on the back of the small bag and the main bag on the side; The waist belt is non-fixed, and a detachable movable waist belt is used. Each bag can be used separately according to needs or combined with the main bag according to various needs and loading capacity.

Claims

1. Multi-point force-bearing method and arrangement of backpack straps.

2. A decomposable combination model consisting of a main bag, a computer bag, a travel bag and a small bag.
