Title: Baby carrying harness

Description:
TECHNICAL FIELD 
     The present disclosure relates to baby products, and more particularly to an adjustable baby carrying harness. 
     BACKGROUND 
     Existing baby carrying harnesses can be divided into horizontal holding type, front carrying type, back carrying type, etc., according to different holding methods. Among them, the front carrying harness is most widely used due to its advantages facilitating operations and timely observation of babies. 
     In a front carrying harness, during a long time using, the user&#39;s shoulders will carry a larger load on due to the baby&#39;s weight pulled forward. Moreover, in a cross-shaped formed by shoulder strap members crossed on back, the load on the user&#39;s shoulders can be well partially dispersed on the back, thereby reducing the burden on the shoulders of the user and the fatigue of long-term use. Such shoulder strap members solve the problem of overloading on the user&#39;s shoulders to some extent, however, for users with different shoulder widths and different heights, in this kind of crossed shoulder strap members, because the position of the crossing point cannot be moved, positions of the shoulder strap members cannot be adjusted. Accordingly, users of different heights and shoulder widths cannot adjust or fix the crossing position to the best, so the purpose of reducing the burden on the user cannot be achieved. 
     For this, it is always believed in the industry, only such a baby carrying harness that is designed to distribute the burden of the baby to the user&#39;s shoulders, back and waist is the most practical and most easily promoted baby carrying harness. 
     Therefore, there is an urgent need for a baby carrying harness that can be adaptively adjusted according to the different body types of different users, such that the shoulders, backs and waists of the users can be uniformly stressed at the same time.

     DETAILED DESCRIPTION 
     In order to explain the technical content and structural features of the disclosure, the following description will be further will be further provided in combination with the embodiment and the accompanying drawings. 
     As shown in  FIGS. 1-3 and 6 , a baby carrying harness  100  of the disclosure includes a back carrying assembly  1  that may be worn on a user and a support sheet  2  for carrying a baby that is connected to the back carrying assembly  1 . The back carrying assembly  1  includes a waist member  13  and two shoulder strap members  11 . A front end of each of the shoulder strap members  11  is connected to an upper part of the support sheet  2 , and a rear end of each of the shoulder strap members  11  is connected to a middle of the support sheet  2 . The two shoulder strap members  11  crosswise and slidably pass through a shoulder strap fixing member  12 , and the shoulder strap members  11  are arranged crossed on the back of the user by the shoulder strap fixing member  12 . A crossing position of the two shoulder strap members  11  is adjusted by sliding of the shoulder strap fixing member  12 , and at the same time, by sliding of the shoulder strap fixing member  12 , an adjustment of the distance between the two shoulder strap members  11  is realized. The waist member  13  is connected to a lower part of the support sheet  2 . By arranging the shoulder strap members  11  in a crossed structure according to the disclosure, not only the loads on the shoulders of the user are well distributed on the user&#39;s back, but also the shoulder strap members  11  are effectively prevented from slipping off, so the shoulder strap members  11  are safe and reliable. At the same time, by sliding of the shoulder strap fixing member  12 , the crossing position of the two shoulder strap members  11  may be adjusted in real time. Accordingly, users with different shoulder widths and different heights may adjust the crossing position of the two shoulder strap members  11 , such that the crossing position of the two shoulder strap members  11  may be adjusted and fixed to a carrying position to carry load that is suitable for the user&#39;s own conditions, so the shoulders, backs and waists of the users may be uniformly stressed at the same time, and the burden on the user&#39;s shoulders may be reduced and the user&#39;s fatigue feeling may be delayed. 
     As shown in  FIGS. 2 and 6 , specifically, the shoulder strap fixing member  12  has two crosswise channels for the two shoulder strap members  11  to slidably pass through correspondingly, and the two shoulder strap members  11  accordingly sliding through the channels crosswise. Preferably, the shoulder strap fixing member  12  is in a hollow structure, and the shoulder strap fixing member  12  defines four through holes respectively penetrating the hollow structure in two crossing directions, i.e., a first through hole  121 , a second through hole  122 , a third through hole  123 , and a fourth through hole  124 . Among them, the first through hole  121  and the second through hole  122  are directly opposite, the third through hole  123  and the fourth through hole  124  are directly opposite, and the two through holes directly opposite to each other are used for the same shoulder strap member  11  to pass through. 
     As shown in  FIGS. 7 and 8 , specifically, the shoulder strap fixing member  12  of the disclosure is in a diamond structure. More specifically, a larger inner angle of the diamond structure of the shoulder strap fixing member  12  of the disclosure is 105°. When selecting a material for the shoulder strap fixing member  12 , it is necessary to take both flexibility and rigidity into account, so as to satisfy requirements of both the comfort of the user and the stability of the structure. Specifically, the shoulder strap fixing member  12  needs to strengthen rigidity at a position close to the crossing point of the shoulder straps. For example, the shoulder strap fixing member  12  of the disclosure is made of a TPE material. An inner side of the shoulder strap fixing member  12  is covered with an ABS material layer  125 , so as to improve a hardness of the structure of the shoulder strap fixing member  12 , thereby improving a firmness and durability of the baby carrying harness  100 . 
     As shown in  FIGS. 1 and 6 , specifically, each of the shoulder strap members  11  is in an adjustable length structure, and users with different shoulder widths and different heights may adaptively adjust the lengths of the shoulder strap members  11  according to their actual conditions, so as to achieve a best posture. Specifically, the upper part of the support sheet  2  and the front end of each of the two shoulder strap members  11  are in a detachable structure. Specifically, the front end of each of the shoulder strap members  11  is detachably connected to the upper part of the support sheet  2  by a first fixing buckle  111  that is adjustable in length and capable of being snap-fit connected. Specifically, the first fixing buckle  111  includes a male buckle  111   a  and a female buckle  111   b  snap-fit connected to the male buckle  111   a.  Both ends of the upper part of the support sheet  2  are respectively connected to the male buckle  111   a.  A bottom of the male buckle  111   a  is connected to an “ ” shaped buckle  113  (the “ ” shaped buckle  113  is a common buckle used for adjusting the length of a weaved strap). The female buckle  111   b  snap-fit connected to the male buckle  111   a  is fixed to the front end of one of the two shoulder strap members  11 . By snap-fit connection of the male buckle  111   a  and the female buckle  111   b,  a detachable connection between the upper part of the support sheet  2  and the front ends of the two shoulder strap members  11  is achieved. More specifically, the “ ” shaped buckle  113  is connected to a weaved strap structure  114 , and a connection length between the upper part of the support sheet  2  and the front end of one of the shoulder strap members  11  may be adjusted by sliding of the “ ” shaped buckle  113  on the weaved strap structure  114 . Of course, the first fixing buckle  111  may also be a convenient and practical buckle such as a plug-in buckle, a snap buckle, a magic tape, a fixing buckle and a fixing hole, and the like. The first fixing buckle  111  may facilitate the user to disassemble and separate the upper part of the support sheet  2  from the front ends of the two shoulder strap members  11 . In using, the user only need to hold the baby to the front of his/her body, then use the support sheet  2  to cover the baby, and close the first fixing buckle  111 , so a single person can complete the entire process of carrying the baby. 
     As shown in  FIGS. 3 and 4 , a rear end of each of the shoulder strap member  11  and one end of the waist member  13  are in a weaved strap structure  114 , the rear end of each of the shoulder strap members  11  is detachably connected to the middle of the support sheet  2  by a second fixing buckle  112  that is adjustable in length and may be snap-fit connected. Both ends of the waist member  13  are detachably connected by a third fixing buckle  131  that is adjustable in length and may be snap-fit connected. Specifically, each of the second fixing buckles  112  includes a male buckle  112   a  and a female buckle  112   b  that is snap-fit connected to the male buckle  112   a.  Each of the rear ends of the two shoulder strap members  11  is connected to one male buckle  112   a  by one “ ” shaped buckle  113 , respectively. A length of each of the shoulder strap members  11  is adjusted by sliding of the “ ” shaped buckle  113  on the weaved strap structure  114 . The female buckles  112   b  snap-fit connected to the male buckles  112   a  are fixed on both sides of the middle of the support sheet  2 . By the snap-fit connections of the male buckles  112   a  and the female buckles  112   b,  the detachable connections between the rear ends of the shoulder strap members  11  and the middle of the support sheet  2  are achieved. The third fixing buckle  131  includes a male buckle  131   a  and a female buckle  131   b  that is snap-fit connected to the male buckle  131   a,  and one end of the waist member  13  is connected to one male buckle  131   a  by one “ ” shaped buckle  113 . By sliding of the “ ” shaped buckle  113  on the weaved strap structure  114 , a length of the waist member  13  is adjusted. The female buckle  131   b  snap-fit connected to the male buckle  131   a  is fixed to the other one end of the waist member  13 . By the snap-fit connection of the male buckle  131   a  and the female buckle  131   b , detachable connections of the two ends of the waist member  13  are achieved. Of course, the second fixing buckle  112  or the third fixing buckle  131  may also be a convenient and practical buckle such as a plug-in buckle, a snap buckle, a magic tape, a fixing buckle and a fixing hole, and the like. 
     As shown in  FIGS. 4 and 5 , according to the disclosure, an adjustable fixing buckle  132  for adjusting a width and a height of the support sheet  2  is disposed in the connection between the waist member  13  and the lower part of the support sheet  2 . The adjustable fixing buckle  132  has a buckling state and an unlocking state, and the width and the height of the support sheet  2  are smaller when the adjustable fixing buckle  132  is in the buckling state than the width and the height of the support sheet  2  when the adjustable fixing buckle  132  is in the unlocking state. As shown in  FIG. 4 , the adjustable fixing buckle  132  is in the unlocking state, both the width and the height of the lower part of the support sheet  2  are relatively large, so a larger baby may be covered. As shown in  FIG. 5 , the adjustable fixing buckle  132  is in the buckling state, such that both the width and the height of the lower part of the support sheet  2  are reduced, so it may be used for a smaller baby. More specifically, the adjustable fixing buckle  132  may include a drawstring  1321 , and cooperatively a button  1322  and a fixing ring  1323 . When the button  1322  is buckled in the fixing ring  1323 , the drawstring  1321  pulls the support sheet  2  to fold to reduce its width and height. When the button  1322  is separated from the fixing ring  1323  to be unlocked, the support sheet  2  restores to its original width and height. Of course, the adjustable fixing buckle  132  may also be a convenient and practical buckle such as a plug-in buckle, a snap or a magic tape or the like. The adjustable fixing buckle  132  may adaptively adjust the width and height of the support sheet  2  according to the changes of the baby&#39;s body shape at different ages, which is more suitable for the baby&#39;s body shape, and especially supports the baby&#39;s buttocks and legs more firmly, thereby providing a safer and more comfortable seating experience. 
     According to the disclosure, the shoulder strap members  11  of the baby carrying harness  100  are crossed in respect to each other on the back of the user by the shoulder strap fixing member  12 , such a crossed structure not only distributes the load on the user&#39;s shoulders to the user&#39;s back, but also effectively prevents the shoulder strap members  11  from slipping off, so as to improve the stability and firmness of the front carrying harness, and ensure that the baby is kept in a more stable position, thereby ensuring the safety of the baby. On the other hand, in the baby carrying harness  100  of the disclosure, the crossing position of the two shoulder strap members  11  are adjusted through sliding of the shoulder strap fixing member  12 , so users with different shoulder widths and different heights may adaptively adjust the crossing position of the two shoulder strap members  11  according to their actual conditions, such that the crossing position of the two shoulder strap members  11  may be adjusted and fixed to a carrying position suitable for the user&#39;s own conditions, such that the shoulders, backs and waists of the users may be uniformly stressed at the same time, the burden on the user&#39;s shoulders may be reduced and the user&#39;s fatigue feeling may be delayed. 
     As shown in  FIGS. 9-11 , according to the second embodiment of disclosure, the upper part of the support sheet  2  and the front ends of the two shoulder strap members  11 ′ are in an integrated structure, and both ends of the upper part of the support sheet  2  respectively extend independently to form the two shoulder strap members  11 ′. In using, the two shoulder strap members  11 ′ are wound to the front and are detachably connected to the middle of the support sheet  2  by the second fixing buckle  112  whose length is adjustable and may be snap-fit connected. Of course, the upper part of the support sheet  2  and the front ends of the two shoulder strap members  11 ′ may also be fixedly connected to each other by sewing to form an integrated structure, however, the disclosure is not limited to the specific method for achieving the integrated structure of the upper part of the support sheet  2  and the front ends of the two shoulder strap members  11 ′. The integrated structure may reduce the use of buckle components, makes the overall structure of the baby carrying harness  100  more concise and convenient for storage and carrying. 
     As shown in  FIGS. 12-14 , according to the third embodiment of the disclosure, the back carrying assembly  1  further includes a transition buckle  133 , a sliding buckle  15 , and side shoulder straps  14 . The transition buckle  133  is connected to the waist member  13 . The rear end of each of the shoulder strap members  11  changes direction by sliding through the transition buckle  133  and then connects to the middle of the support sheet  2 . The sliding buckle  15  slidably passes through the rear end of one of the shoulder strap members  11 . The sliding buckle  15  is connected to a rear end of each of the side shoulder straps  14 , and a front end of each of the side shoulder straps  14  is connected to the upper part of the support sheet  2 . Moreover, the rear end of each of the side shoulder straps  14  is slidably connected to the rear end of one of the shoulder strap members  11  by the sliding buckle  15 . Specifically, the side shoulder straps  14  and the support sheet  2  form an integrated structure. The rear end of each of the shoulder strap members  11  forms a transitional connection with the waist member  13  through the transition buckle  133 , such that the shoulder strap members  11  have a larger stressed area, and further reduces the burden on the user&#39;s shoulders and waist, such that the user&#39;s shoulders, back and waist are more uniformly stressed at the same time. The side shoulder straps  14  further strengthens the connection between the support sheet  2  and the shoulder strap members  11 , effectively preventing the baby from sliding off the side of the baby carrying harness  100 , thereby further ensuring the safety of the baby. Specifically, the rear end of each of the shoulder strap members  11  is in the weaved strap structure  114 , and the weaved strap structure  114  slidably passes through the waist member  13 . 
     As shown in  FIGS. 1-14 , in the baby carrying harness  100  of the disclosure, the shoulder strap members  11  are crossed on the user&#39;s back through the shoulder strap fixing member  12 , which may well disperse the load on the user&#39;s shoulders to the user&#39;s back, and effectively prevent the shoulder strap members  11  from slipping off, so as to improve the stability and firmness of the front carrying harness, and ensure that the baby is kept in a more stable position, thereby ensuring the safety of the baby. On the other hand, the baby carrying harness  100  of the disclosure may adjust the crossing position of the two shoulder strap members  11  by sliding of the shoulder strap fixing member  12 , so users of different shoulder widths and different heights may adaptively adjust the crossing position of the two shoulder strap members  11  according to their own actual conditions, such that the shoulders, backs and waists of the users may be uniformly stressed at the same time, the burden on the user&#39;s shoulders may be reduced and the user&#39;s fatigue feeling may be delayed. Moreover, by the snap-fit connections between the male buckles and the female buckles of the first fixing buckle  111 , the second fixing buckle  112 , and the third fixing buckle  131 , quick detached separations between various components may be achieved, such that the operation to carry the baby by using the baby carrying harness  100  will be more convenient and quicker; furthermore, the adjustable fixing buckle  132  may adaptively adjust the width and height of the support sheet  2  according to changes in the body shapes of babies of different ages, so the baby carrying harness  100  is more versatile. 
     What disclosed above are only preferred embodiments of the disclosure, and the scope of the disclosure certainly cannot be limited by this. Therefore, any equivalent changes made according to the scope of the disclosure still belong to the disclosure.
