Description
Technical field
The present invention relates to a kind of school bag, particularly the dynamic adjustable school bag of one.
Background technology
School bag has been indispensable article in learning life for student, and school bag and the healthy of student are also closely bound up.Along with the increase of students lessons task, the weight of school bag also correspondingly increases to some extent.
In order to solve the problem that student bears a heavy burden, the research that lot of domestic and foreign scholar is also correlated with, mainly research is different bears a heavy burden for the impact of human motion, and then research plantar nervous arch, the impact of gait feature and corresponding compensatory strategy, biomethanics, gait the aspect such as adjustment and energy ezpenditure, the change of body gesture, the shock-absorbing capacity of footwear and improvement, and for student's school bag bear improve study fewer.In order to solve the problem that student bears a heavy burden, by constantly designing improvement, develop pull bar school bag, but pull bar school bag is but also existing some problems in varying degrees, such as sleet sky use inconvenient, by bus and use inconvenience when going upstairs, easy overturning etc. when pulling speed fast, long-time dilatory weight also can produce certain harm for student's body development.When a certain position of toter's health is stressed for a long time under the state of bearing, so toter then can feel to bear discomfort, now will think that the comfortableness of bearing of school bag is not fine, and existing school bag is difficult to reasonably regulate.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the invention is to propose a kind of dynamic adjustable school bag, can for the long toter for 44cm-46cm of the back of the body, by the dynamic adjustments of shoulder belt, effective comfortableness improved school bag and bear, reduce the incidence of disease that student bears disease, there is easy to use, that comfortableness is good feature.
To achieve these goals, the technical solution used in the present invention is:
A kind of dynamic adjustable school bag, comprise inclusion 1, bottom the back panel of inclusion 1, left and right is fixedly connected with a latch closure 2 respectively, the top of inclusion 1 is fixedly connected with two shoulder belts 3, the end of shoulder belt 3 is fixedly connected with ribbon 4, shoulder belt 3 and ribbon 4 are respectively equipped with row's box 5 and sub-buckle 6, and ribbon 3, through latch closure 2, is fixedly connected with sub-buckle 6 by box 5.
The number ratio sub-buckle 6 of described box 5 at least many 2.
The quantity of described sub-buckle 6 is 4-6.
Due to the shoulder belt that the present invention adopts dynamic to regulate, for the long toter for 44cm-46cm of the back of the body in the process of bearing, when shoulder is stressed feel more greatly sense of fatigue time, by regulating the relative position relation of box and sub-buckle, waist can be transferred to by stressed for part in time, to slow down the constriction of shoulder, avoid the stressed for a long time of shoulder, otherwise, also can be transferred to shoulder by stressed for part by waist, avoid the stressed for a long time of waist; Make the stressed size of shoulder and waist be in dynamic translation state by dynamic adjustments, to reach the improvement of bearing comfortableness, there is easy to use, that comfortableness is good feature.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See Fig. 1, a kind of dynamic adjustable school bag, comprise inclusion 1, bottom the back panel of inclusion 1, left and right is fixedly connected with a latch closure 2 respectively, the top of inclusion 1 is fixedly connected with two shoulder belts 3, the end of shoulder belt 3 is fixedly connected with ribbon 4, shoulder belt 3 and ribbon 4 are respectively equipped with row's box 5 and sub-buckle 6, ribbon 3 is through latch closure 2, be fixedly connected with sub-buckle 6 by box 5, by the stressed size regulating the relative position relation between box 5 and sub-buckle 6 to change shoulder and waist, make stressedly to reach dynamic translation, improve the comfortableness of bearing.
See Fig. 2, the quantity of described box 5 is 8, and the quantity of described sub-buckle 6 is 4, represents respectively with a, b, c, d, and interval 2cm between adjacent sub-buckle.
By the experiment test of Pliance-x pressure pad test macro, analyze the surge pressure test data of the shoulder drawing the long experimenter of the different back of the body.By the further analysis to experimental result, draw and obtain carrying on the back the long surge pressure change curve for 44cm, 46cm experimenter.
See Fig. 3, the long shoulder surge pressure change curve for 44cm experimenter of the back of the body.From map analysis, experimenter is when testing " 3 " position (corresponding sub-buckle b), and shoulder is stressed minimum, and now waist location is stressed larger; Experimenter is when testing " 5 " position (corresponding sub-buckle d), and shoulder is stressed maximum, and now waist location is stressed less.When this experimenter's waist feels fatigue, can by regulating the relative position relation between box 5 and sub-buckle 6, fixed position is adjusted to " 5 " position (corresponding sub-buckle d), the power that shoulder is shared is greater than the stressed of waist; When shoulder feels fatigue, by regulating, fixed position being adjusted to " 3 " position (corresponding sub-buckle b), making waist stress be greater than shoulder.By the dynamic adjustments of box 5 and sub-buckle 6, just can make to bear and stressedly between shoulder and waist, carry out dynamic translation, thus better bear comfortableness for toter provides.
See Fig. 4, the long shoulder surge pressure change curve for 46cm experimenter of the back of the body.From map analysis, experimenter test " 4 " position (corresponding sub-buckle a) time, shoulder is stressed minimum, and now waist stress is larger; When testing " 6 " position (corresponding sub-buckle c), shoulder is stressed maximum, and now waist location is stressed less.When this experimenter's waist feels fatigue, can by regulating the relative position relation between box 5 and sub-buckle 6, fixed position is adjusted to " 6 " position (corresponding sub-buckle c), the power that shoulder is shared is greater than the stressed of waist; When shoulder feels fatigue, (corresponding sub-buckle a), makes waist stress be greater than shoulder by adjustment, fixed position to be adjusted to " 4 " position.By the dynamic adjustments of box 5 and sub-buckle 6, just can make to bear and stressedly between shoulder and waist, carry out dynamic translation, thus better bear comfortableness for toter provides.
Operation principle of the present invention is:
First the back of the body measuring toter is long, namely measures C7 (position that rear neck end bone is outstanding, the intersection of neck and the shoulder) length to pelvis line between edge, is the measured value that the back of the body is long.After the mensuration back of the body is long, sub-buckle 6 gear that toter selects " 44 " or " 46 " corresponding according to the measured value of back of the body length.In the process that toter bears, both shoulders stress value adds that the small of the back stress value then approximates the weight of school bag, and its weight is born by shoulder and waist.When toter feels shoulder or lumbar fatigue, regulate the stressed of shoulder and waist by regulating the relative position relation between box 5 and sub-buckle 6.
