Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of backpacks, and in particular relates to a split school bag. Background Art
[0002] The existing school bags for students are large and all one-piece. When students carry the school bags, they mainly rely on the strength of their shoulders and waist to bear the pressure of the school bags. Since the school bags are relatively large, they are heavier with more textbooks and stationery inside. When carrying the school bags, the upper part of the front end of the school bags contacts the student's back, while the lower part of the front end is separated from the waist. This force-bearing method has a single support point (mainly the shoulder), and the pulling force of the school bags is transmitted from the shoulders to the waist, resulting in greater force on the students' shoulders and waists. The shoulders will also have a large degree of friction, which is not only physically demanding and laborious to carry, but also not conducive to the healthy growth of teenagers, which is reflected in the laborious bending over when walking, and the long-term carrying of the one-piece large school bags easily leads to hunchbacks. Utility Model Content
[0003] In view of the problems of the prior art, the present invention discloses a split-type schoolbag, which changes the one-piece structure of the traditional schoolbag. By dividing the schoolbag body into a first schoolbag and a second schoolbag, a plurality of support points can be provided for the schoolbag body. By utilizing the ingenious weight-balancing principle, the stress state of the traditional one-piece schoolbag is improved, making it more comfortable and labor-saving for students to carry the schoolbag.
[0004] To achieve the above purpose, the technical solution of this novel invention is:
[0005] A split schoolbag comprises a schoolbag body, wherein the schoolbag body comprises a first schoolbag and a second schoolbag arranged up and down, the side surfaces of the first schoolbag and the second schoolbag are connected by a buckle mechanism, and the front ends of the first schoolbag and the second schoolbag are connected by shoulder straps respectively.
[0006] Preferably, the front end of the first backpack is used to abut against the shoulder of the wearer, the front end of the second backpack is used to abut against the waist of the wearer, and the shoulder strap is a shoulder strap structure with adjustable length.
[0007] Preferably, the buckle mechanism comprises a male buckle and a female buckle, and the female buckle and the male buckle are fixedly connected to the side of the first school bag or the second school bag respectively.
[0008] Preferably, the outer surface of the shoulder strap is provided with a marking line for marking the telescopic length of the shoulder strap.
[0009] Preferably, a horizontal strap is provided between the two shoulder straps at a position opposite to the wearer's chest, the two ends of the horizontal strap are respectively fixedly connected to the shoulder straps on both sides, and a decoration is provided in the middle of the horizontal strap.
[0010] Preferably, the first school bag and the second school bag are provided with side pockets and back pockets on the sides and backs respectively.
[0011] Preferably, the front sides of the first schoolbag and the second schoolbag are respectively provided with elastic cushion layers.
[0012] Preferably, the elastic cushion layer is sewn and connected to the front side of the first school bag or the second school bag via a connecting block.
[0013] Preferably, the elastic cushion layer is provided with ventilation holes or elastic massage protrusions.
[0014] Preferably, a sponge pad is provided at the upper part of the shoulder strap where it contacts the shoulder of the wearer and inside the cross strap.
[0015] The beneficial effects of the new split-type school bag are:
[0016] 1. The shoulders and waist of the wearer are in contact with the front ends of the first backpack and the second backpack respectively, so that the original one-piece backpack body is changed from only in contact with the shoulders to in contact with the shoulders and waist, so that the wearer can bear the weight of the backpack body through the chest, shoulders, shoulders and waist at multiple points to disperse the pressure.
[0017] 2. The first backpack and the second backpack have a mutually coordinated force relationship, which is reflected in the following aspects: on the one hand, the second backpack transmits the pulling force through the shoulder strap, thereby reducing the downward pulling force of the first backpack through the counterweight principle; the first backpack also transmits the pulling force through the shoulder strap, thereby increasing the forward and upward pulling force of the second backpack. Since the downward pressure of the first backpack is reduced due to the counterweight of the second backpack, and the upward pulling force applied by the first backpack to the second backpack, the wearer can feel more comfortable and less labor-intensive.
[0018] 3. When using the new model, the wearer puts the backpack body on his back, unfastens the buckles on both sides, and adjusts the length of the shoulder straps so that the first backpack and the second backpack are in contact with the shoulder and waist respectively. The first backpack and the second backpack conduct force to each other, the second backpack presses forward against the waist to straighten the wearer's waist, and the first backpack pulls the chest backward to straighten the wearer's chest, which can produce a good shaping effect on the wearer and avoid the defect of hunchback caused by long-term carrying of traditional one-piece large backpacks.

[0024] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
[0025] The following embodiments may be understood as a part of a local structure or method that is expressed separately in the present invention, or may be understood as a combination of the embodiments to explain the connotation of a larger structure or method of the present invention.
[0026] Example 1
[0027] A split school bag, such as Figure 1-4 As shown, it includes a backpack body, which includes a first backpack 1 and a second backpack 2 arranged up and down, the sides of the first backpack 1 and the second backpack 2 are connected by a buckle mechanism 3, and the front ends of the first backpack 1 and the second backpack 2 are connected by shoulder straps 4 respectively.
[0028] Example 2
[0029] like Figure 1 As shown, the front end of the first backpack 1 is used to abut against the shoulder of the wearer, the front end of the second backpack 2 is used to abut against the waist of the wearer, and the strap 4 is a strap structure with adjustable length (such as Figure 1-3 As shown, the length-adjustable shoulder strap structure is prior art and will not be described in detail).
[0030] In this embodiment, Figure 1 As shown, the shoulders and waist of the wearer are in contact with the front ends of the first backpack and the second backpack respectively, so that the original one-piece backpack body that only contacts the shoulders is changed to not only contacting the shoulders but also the waist, so that the wearer can bear the weight of the backpack body through the chest, shoulders, shoulders, and waist at multiple points to disperse the pressure.
[0031] More importantly, the first backpack and the second backpack have a mutually coordinated force relationship, which is reflected in: on the one hand, the second backpack transmits tension through the shoulder straps, thereby reducing the downward tension of the first backpack through the counterweight principle; the first backpack also transmits tension through the shoulder straps, thereby increasing the forward and upward tension of the second backpack. Since the downward pressure of the first backpack is reduced due to the counterweight of the second backpack and the second backpack is pulled upward by the first backpack, the wearer will feel more comfortable. At the same time, since the second backpack is pulled forward and upward by the first backpack, the second backpack can be pressed against the waist of the wearer, which has a good shaping effect.
[0032] Example 3
[0033] like Figure 1 , 2 As shown in FIG. 3 , the buckle mechanism 3 includes a male buckle 31 and a female buckle 32 , and the female buckle and the male buckle are fixedly connected to the side of the first school bag 1 or the second school bag 2 respectively.
[0034] In this embodiment, Figure 1-3 As shown, male buckles and female buckles are commonly used technologies. When making, a buckle mechanism that can achieve the above functions can be selected.
[0035] Example 4
[0036] like Figure 3 As shown, the outer surface of the shoulder strap 4 is provided with a marking line 10 for marking the extension length of the shoulder strap. The purpose of providing the marking line is to enable the wearer to easily adjust the shoulder straps on both sides to equal lengths to avoid uneven stress on the two shoulders. Figure 3 As shown, the commonly used shoulder strap can be adjusted in length by pulling down the lower shoulder strap head, and the extension and contraction range of the shoulder strap can be quickly identified by referring to the marking line 10 on the shoulder strap.
[0037] like Figure 3 As shown, a horizontal belt 8 is provided between the two shoulder straps 4 at a position opposite to the wearer's chest, and the two ends of the horizontal belt 8 are respectively fixedly connected to the shoulder straps 4 on both sides, and a decoration 9 is provided in the middle of the horizontal belt 8. The horizontal belt is provided to increase the contact area between the shoulder strap and the wearer's chest and disperse the force. At the same time, the wearer can hold the horizontal belt with his hands to avoid the shoulder strap exerting excessive pressure on the chest and causing discomfort.
[0038] Example 5
[0039] like Figure 1-4 As shown, the first school bag 1 and the second school bag 2 are provided with side pockets and back pockets on the sides and backs respectively, which is a common design and is usually used to carry sundries such as stationery.
[0040] Example 6
[0041] like Figure 3 , 4As shown, the front sides of the first school bag 1 and the second school bag 2 are respectively provided with elastic cushion layers 5 which can be made of elastic rubber or fabric to improve the comfort of the back or waist.
[0042] like Figure 4 As shown, the elastic pad layer 5 is sewn and connected to the front of the first school bag 1 or the second school bag 2 through a connecting block 51 , so that there is a certain gap between the elastic pad layer 5 and the front of the first school bag 1 or the second school bag 2 .
[0043] like Figure 3 As shown, the elastic cushion layer 5 is provided with ventilation holes 6 or elastic massage protrusions. The ventilation holes 6 are conducive to heat dissipation of the wearer's skin in summer; the elastic massage protrusions can massage the shoulders, back or waist during the process of carrying the schoolbag, which is conducive to relieving the wearer's fatigue.
[0044] like Figure 1 , 2 As shown, the upper portion 41 of the shoulder strap that contacts the shoulder of the wearer and the cross strap 8 are both provided with sponge pads to make the wearer more comfortable.
[0045] When the new type is used, the wearer puts the backpack body on his back, unfastens the buckles on both sides, and adjusts the length of the shoulder straps so that the first backpack and the second backpack are in contact with the shoulder and waist respectively. The mutual force transmission between the first backpack and the second backpack can make the wearer feel more comfortable and less labor-saving; at the same time, the second backpack presses forward against the waist to make the waist straighten, and the first backpack pulls the chest backward to make the chest straighten, which can produce a good shaping effect on the wearer and avoid the defect of the traditional one-piece large backpack that is easy to cause hunchback when carried for a long time. When designing, the size of the first backpack can be equal to or slightly larger than the second backpack, and students can classify books and stationery and store them in the first backpack and the second backpack. When the weight of the first backpack is greater than or equal to the weight of the second backpack, the wearer can get a better experience than the commonly used one-piece backpack.
[0046] It should be noted that the present invention is not only intended to describe the structure of a school bag, but also any backpack product used for other purposes, if it adopts the same technical structure as the present invention, is also within the protection scope of the present invention.
