Abstract

The utility model relates to a back protection bag which comprises a bag body and straps; the straps are symmetrically sewed on both sides of the bag body; the bag is characterized in that a back protection board is fixedly arranged on the axis of the back part of the bag body; and the back protection board is provided with a radian curve which is matched with the back. When being carried, the back part of the bag is glued to the back of human body to form reasonable stress distribution. For the physical structure of the back, the utility model designs the back part of the bag to meet the back curve of human body, balance the stress of human body, be reasonably distributed on the area of the back, reduce the pressure on both shoulders and effectively prevent the possibility of inclination of human body and deformation of the back because of the stress on the shoulders with the action of the back protection board, and the multiple humanized design further improves the functions of the bag.

Description

A kind of back bag that protects

Technical field:

The utility model belongs to the knapsack field, and particularly a kind of have a knapsack that protects the ridge function, especially is fit to the student and bears.

Background technology:

Knapsack has been the requirement during people live, and especially student group is all the more so.Long-term overweight bearing, the teenager's bone flexural deformation in very easily causing growing up.Existing knapsack or school bag, it mainly bears a heavy burden and concentrates on the both shoulders, and unconscious the stressed of shoulder that alleviate by bending over of human body conditioned reflex meeting especially plays supplemental support by the waist more than the pelvis to the knapsack bottom, the aggravation lumbar fatigue, long-term use must cause bad consequence.

Summary of the invention:

The purpose of this utility model is that a kind of energy of design is docile in the knapsack of human body back and tool protection vertebra.

Technical solutions of the utility model are achieved in that a kind of back bag that protects, and comprise bag and braces, and the braces symmetry is sewn to the bag both sides, it is characterized in that being fixed with one on the axis, bag back protects epimere, and this protects epimere and has the radian curve that coincide with back.The knapsack back is close on the human body back, is formed reasonable force distribution.

The described epimere that protects is an alloy in lightweight thin plate, installs to be meant the bag back along being sewed with an opening rectangular bag up on the axis, protect epimere insert should rectangular bag in, both simple, convenient for assembly again.

Describedly protect the arc sheet material that epimere is a plastic rubber shaping, this protect the epimere symmetry offer offer at least on a plurality of hollow out air-vents and the axis can-with the fixing hole of bag rivet clasp, mat one fixture is with both rivet clasps together.Be close to back more in large area, the weight of knapsack can be disperseed, be unlikely to concentrate on a certain zone.

Described protecting offers three fixing holes in upper, middle and lower on the epimere axis.

The described epimere that protects vertically is distributed with symmetrical reinforcement on the faying face at bag back, improve the rigidity intensity of protecting epimere.

The described epimere bottom of protecting has symmetrical abduction alar part, and mat abduction alar part is adjacent to the waist above pelvis, plays the protection supporting role.

Both sides, described bag back and bottom are filled with the elastic insert of projection, two-side elastic liner camber shape symmetrical distribution structure respectively.Alleviate the friction with the back, also can form necessary gas-permeable channels.

Described bag two sides are sewed with zip mode cup pkt. flap, and the cup bag is embedded in the bag, are that the knapsack both sides are not rude toward the bag convex behind placement water glass or the bottle.

Described bag front portion is sewed with upper and lower two male type Stationery bags independently, and the liner towards bag one side and bottom adopts waterproof fabrics at least; Its middle and lower part Stationery bag one side outwardly is that two kinds of linings are spliced, and the top lining is ventilative lining.Top provides need of placing stationery, and the Stationery bag of bottom promptly can be used to storage of umbrella and so on and has water stain article, and perhaps food can not infiltrate in the bag, and can be by the lining discharge moisture of breathing freely.

Described bag suturing part is embedded with reflecting strips, improves the security of going out walking in the night.

The utility model is at the physiological make-up of back, the back of design knapsack meets the human vertebra curve, balance human body stress, rationally be distributed in dorsal area, alleviate the pressure of both shoulders portion, mat protects the effect of epimere, also can effectively prevent because of both shoulders stressed, and causing that health is crooked, the possibility of the deformity of spinal column, the function of knapsack is further improved in multiple human oriented design.

The specific embodiment:

With reference to Fig. 1, protect the schematic rear view of back bag, comprise bag 1 and braces 2, braces 2 symmetries are sewn to bag 1 both sides, bag both sides, 1 back and bottom are filled with the elastic insert 3 of projection respectively, two-side elastic liner 3 camber shape symmetrical distribution structures, the lining of making elastic insert is a network cloth, to increase the gas permeability at back; Bag 1 two sides are sewed with zip mode cup pkt. flap 4, and cup bag 41 is embedded in the bag 1, packs into behind water tumbler or the water bottle, does not protrude, and the knapsack both sides are difficult for the barrier of swiping.

With reference to Fig. 2, protect back bag front schematic view, dotted line is for protecting epimere 5 among the figure, and bag 1 front portion is sewed with upper and lower two male type Stationery bags 11 independently, and the liner towards bag 1 one sides and bottom adopts waterproof fabrics at least; Its middle and lower part Stationery bag side outwardly is that two kinds of linings are spliced, and the top lining as grid cloth, had both had the air-moisture-permeable function, and become outward appearance more to be rich in ornamental knapsack with other lining organic assembling, satisfying personalized need for ventilative lining 6; Bag 1 suturing part is embedded with reflecting strips 12, is sent a car in the back and can see the toter clearly, and reflecting strips 12 existing utility functions have decoration functions again concurrently, organically blend in one, and outward appearance is not rude yet.Be fixed with one on the axis, bag 1 back and protect epimere 5, this protects the radian curve that epimere 5 has and back coincide, and makes the more docile human body back in knapsack back.

With reference to Fig. 3, protect the arc sheet material that epimere 5 is a plastic rubber shaping, this protect epimere 5 symmetries offer offer at least on a plurality of hollow out air-vents 51 and the axis one can with the fixing hole 52 of bag rivet clasp, mat one fixture is with both rivet clasps together; In case of necessity, can offer three fixing holes in upper, middle and lower on epimere 5 axis protecting, make integral body more docile; In addition, protect epimere 5 and on the faying face at bag back, vertically be distributed with symmetrical reinforcement 53, increase intensity longitudinally, lightening material weight; Moreover, protect the abduction alar part 54 that epimere 5 bottoms have symmetry, extensible setting off to the waist place of human pelvis top increases the support of stern waist to knapsack.

With reference to Fig. 4, protect epimere 5 except that above-mentioned plastic rubber shaping, also can be an alloy in lightweight thin plate, protect installing between epimere 5 and knapsack and be meant that bag 1 back is along being sewed with an opening rectangular bag up on the axis, protect epimere 5 and insert in this rectangular bag, also can reach and protect the ridge effect.
