Title: Child carrying device

Description:
TECHNICAL FIELD 
     The present invention relates to a child carrying device for carrying a child by a user on the user&#39;s shoulders. More particularly the present invention relates to a carrier with a foldable support frame attached to a length-adjustable hipbelt capable of transferring and placing a significant portion of the carried child&#39;s weight onto the user&#39;s hip or waist, and the carrying device is designed to accommodate users of different torso length. 
     BACKGROUND 
     Child carrying devices have been developed wherein the child is positioned onto a user&#39;s shoulders using frame like structures strapped onto the user&#39;s back, however these existing carrying devices often have flaws and are less than optimum. Applicant herein realizes the following areas of improvements need to be addressed by an optimum child carrying device: 
     (1) Because seating the child on top of the user&#39;s shoulders places significant amount of weight and causes major strain on the user&#39;s shoulders, it would be highly beneficial if the carrying device is capable of distributing and transferring a portion of the carried child&#39;s weight onto the user&#39;s hip or waist. 
     (2) Different users may have different height and torso length, it is crucial that such carrying device is designed to accommodate different height and torso length. 
     (3) Users may frequently stop, carrying and unloading the child, such carrying device ideally should be easily portable and easily stored. 
     (4) Users may want to carry additional weight and an optimum carrying device should be configured to accommodate additional loads easily. 
     SUMMARY 
     The present invention relates to a child carrying device for carrying a child over a user&#39;s shoulders. More particularly, the present invention attempts to address the above identified deficiencies of existing child carrying devices. 
     In one aspect, the child carrying device for carrying a child may include the a foldable support frame adapted to provide a means to support the entire carrying device, a child seat support adapted to securely hold the child, a user back harness with a load lifter mechanism adapted to comfortably strap the carrying device onto the user&#39;s shoulders and torso, and a user hipbelt secured about the user&#39;s hip or waist and is adapted to provide a selectable adjoining location which lower ends of the support frame rest on or attach to, receiving and transferring a significant portion of the carried weight onto the user&#39;s hip or waist. 
     In one aspect, the foldable support frame comprises an upper and a lower portion joined by a folding mechanism, whereas the folding mechanism allows the upper portion of the support frame to extend away from the lower portion into a deployed state of the carrying device and allows the upper portion to fold towards the back side to meet the lower portion into a folded state of the carrying device. This allows the carrying device to transition between a deployed state and a folded state that makes the carrying device portable, easily stored, and conserving space when the carrying device is not in use. Further, in some implementations, the length of the lower portion of the support frame may be extendable to further accommodate users of different torso length. For example, extensions may be attached or screwed onto the ends of the support frame to extend the length of the support frame therefore to accommodate user with longer torso length. 
     In one aspect, the child seat support comprises a child back padding for supporting the child&#39;s back, a child seat padding for seating the child, and a length-adjustable child safety strap for securing the child into the child seat support. The child back padding may be attached to the upper portion of the support frame by removably enclosing the upper portion of the support frame, which allows a portion of the child&#39;s weight to be transferred onto the support frame. The child seat padding may be affixed to the child back padding, and the left and right extension portions of the child seat padding may be configured to rest on top of and be attached to a pair of user shoulder straps. This spatial arrangement may allow the child to be securely seated on top of the user&#39;s shoulders, and a portion of the child&#39;s weight to be transferred onto the user&#39;s shoulders and the support frame. In some implementation, the child seat support may comprise additional security strap to provide additional security. In another implementation, the child seat support may comprise a portable and collapsible sunshade removably attached to the child back padding and adapted to extend over the child&#39;s head. 
     In one aspect, the user back harness comprises a user back padding affixed to a pair of user shoulder straps for harnessing the carrying device onto the user&#39;s shoulders and torso, a pair of child leg restraints, a user sternum strap, and a load lifter mechanism adapted to detachably fasten the user back harness onto the lower portion of the support frame below the child seat support. The user back padding and the pair of user shoulder straps may be padded with breathable material or fabric to provide optimum comfort and ventilation to the user while using the carrying device. The pair of user shoulder straps may comprise a pair of child leg restraints adapted to securely restrain the child&#39;s legs to the front the user&#39;s shoulders and safely secure the child onto the child seat support. The user sternum strap may be attached to the pair of user shoulder straps and adapted to extend across the user&#39;s chest at an adjustable length restraining the pair of user shoulder straps from moving sideways. 
     In one aspect, the child seat padding is configured to rest on top of the user back harness, and the left and right extension portions of the child seat support may be configured to rest on top of and be attached to the pair of user shoulder straps. This spatial configuration between the child seat support and the user back harness limits and restrains the child&#39;s legs to the front of the user&#39;s shoulders, providing additional security while the child is secured into the seat. 
     In one aspect, a load lifter mechanism securely attached to the support frame is provided for detachably fastening the user back harness of the carrying device to the support frame of the carrying device. In some implementations, the load lifter mechanism comprises a left member and a right member that are securely affixed to the support frame. When the user is carrying a child using the device, the child exerts a downward gravitational force onto the carrying device, a portion of which is transferred directly on the carrying device&#39;s shoulders, and another portion is exerted onto the support frame. The portion of the downward gravitational force exerted on the support frame can be separated into two force components. One force component travels downward along the support frame to be counter balanced by a force exerted on the support frame by the user hipbelt. Another force component is directed towards the back and is counter balanced by a pulling force exerted by the user back harness via the load lifter mechanism. The load lifter mechanism may further contain a locking mechanism so that during its locked state, the user back harness is securely and safely fastened or hooked onto the load lifter mechanism by for example a strip, and during its unlocked state, the user back harness may be detached from the load lifter mechanism. The load lifter mechanism may be configured in such a way that it may be used as an attachment point attaching additional weight onto the support frame via an attachment mechanism such as a self-locking hook. 
     In one aspect, a user hipbelt is provided for receiving and transferring a significant portion of the carried weight from the support frame onto the user&#39;s hip or waist. The hipbelt may comprise an attachment mechanism affixed to the back side of the hipbelt for providing adjoining locations which allow lower ends of the support frame to rest on, and a safety strap affixed to the hipbelt for tightening the hipbelt about the user&#39;s hip or waist at an adjustable length. Notably, the attachment mechanism may contain multiple sockets, opening slits, or other similar attachment means that are vertically spaced on the hipbelt to allow users to selectively choose an adjoining location in order to accommodate users of different torso length.

     Foldable Support Frame 
       FIGS. 2A-2B  illustrate an example foldable support frame  200 A- 200 B that can be used as the foldable support frame  102  of  FIG. 1B . The support frame  200 A- 200 B includes an upper portion  202  and a lower portion  204  joined by a folding mechanism  206 . 
     The upper portion  202  forms a U-shaped structure  208  having two ends, a first end  214  and a second end  216 . In other implementation, the upper portion may be any suitable structure such as a solid board or padding with a U-shaped outer edge. 
     The lower portion  204  comprises two elongated tubular structures, a first elongated tubular structure  210  and a second elongated tubular structure  212 , whereas the first elongated tubular structure  210  comprises a third end  218  and a fourth end  220 , and the second elongated tubular structure  212  comprises a fifth end  222  and a sixth end  224 . The length of the first and the second elongated tubular structures may be configured to be adjustable, in order to accommodate users of various height and particularly of various torso length. In one implementation, the first and the second elongated tubular structures may comprise a length-adjustable rod twisting either clockwise or counterclockwise to either extend or shorten the length of the first and the second elongated tubular structures. In another implementation, the first and the second elongated tubular structures may comprise attachable extensions at the fourth end and the sixth end to extend the length of the first and the second elongated tubular structures. 
     The folding mechanism  206  joins the upper portion  202  and the lower portion  204  of the support frame  200 A- 200 B and allows the upper portion  202  to extend and fold from the lower portion  204 . Specifically, the folding mechanism  206  comprises a first member  226  and a second member  228 , joining the first end  214  of the upper portion  202  to the third end  218  of the first elongated tubular structure  210 , and joining the second end  216  of the upper portion  202  to the fifth end  222  of the second elongated tubular structure  228 , respectively. 
       FIG. 3  illustrates an example folding mechanism member  300  that can be used as a first member  226  or second member  228  of the folding mechanism  206  of  FIGS. 2A-2B . The folding mechanism member  300  may comprise 1) a narrower-diameter portion  306 , located at the first end  214  or the second end  216  of the upper portion  202  of the support frame  200 A- 200 B; 2) a hollow recess  308  placed at the end  314  of elongated tubular structure  304 , where the elongated tubular structure  304  can be the first elongated tubular structure  210  or the second elongated tubular structure  212  of  FIGS. 2A-2B , and the end  314  can be the third end  218  or the fifth end  222  of the first elongated tubular structure  210  and the second elongated structure  212  of  FIGS. 2A-2B , respectively; and 3) a pull-out unit spring  310 , with its one end fixedly attached to the inner surface of the hollow recess  308  and with its other end fixedly attached to the narrower-diameter portion  306 . 
     During the deployed state of the carrying device (as shown in  FIG. 8A ), the folding mechanism  300  is in its relaxed state, holding the pull-out unit spring  310  and narrower-diameter portion  306  within the hollow recess  308  of the elongated tubular structure  304 , allowing the upper portion of the support frame to extend away from the lower portion of the support frame. 
     During the folded state of the carrying device (as shown in  FIG. 8D ), the folding mechanism  300  is in its pull-out state, extending and exposing its pivot point  316  and the narrower-diameter portion  306  to the outside of the hollow recess  308 , allowing the upper portion of the support frame to pivot towards the back side of the support frame to meet the lower portion of the support frame. 
     Child Seat Support 
     Better illustrated in  FIGS. 4A-4B , the child seat support  400 A- 400 B (e.g. child seat support  104  of  FIGS. 1A-1B ) of the child carrying device for holding a child, comprising a child back padding  402  for supporting the child&#39;s back, a child seat padding  404  for seating the child, and a child safety strap  406  that is length adjustable for securing the child into the child seat support  400 . 
     The child back padding  402  further comprises an upper edge  408 , a lower edge  410 , a left edge  412 , and a right edge  414 . The child back padding  402  is adapted to support the child&#39;s back onto the child seat support  400  and transfer a portion of the child&#39;s weight onto the support frame  432 . In some implementations, the child back padding  402  may removably enclose the upper portion of the support frame in a snugly fashion and securely transfer a portion of the child&#39;s weight onto the support frame  432  through the upper edge  408  of the child back padding  402 . In another implementation, the child back padding  402  may be affixed to the upper portion (not labeled) of the support frame  432  onto its outer edges (including the upper edge  408 , the left edge  412 , and the right edge  414 ) and transfer a portion of the child&#39;s weight onto the support frame through the upper edge  408 , the left edge  412  and the right edge  414  of the child back padding  402 . In some implementations, the child back padding  402  may be made with breathable fabric, rigid enough to provide back support and soft enough to provide comfort to the child while seated in the child seat support  400 . In some implementation, the child seat support  400  may comprise a pair of added security strap (not shown) attached to the left edge  412  and the right edge  414  below the child safety strap  406 , adapted for the child safety strap  406  to loop around and to provide additional security. In some implementations, the child seat support  400  may comprise a portable and collapsible sunshade (not shown), removably attached to the child back padding  402 , and adapted to extend over the child&#39;s head to provide coverage and shade during sun exposure. 
     The child seat padding  404 , comprising an upper edge  422  and a lower edge  424 , is adapted for seating the child and to transfer a portion of the child&#39;s weight onto the child back padding  402  and the user&#39;s shoulders. 
     The upper edge  422  of the child seat padding  404  is securely attached to the lower edge  410  of the child back padding  402 , allowing a portion of the child&#39;s weight placed on the child seat padding  404  transferred to the child back padding  402 . In one implementation, the child back padding  402  and the child seat padding  404  may be one uniform piece of material or fabric. In another implementation, the child back padding  402  and the child seat padding  404  may be two separate pieces of fabric or material affixed or sewed together. 
     The lower edge  424  of the child seat padding  404  may further comprise a left extension portion  416  and a right extension portion  418 , forming an open space  420  in between the left extension portion  416  and the right extension portion  418 , adapted to provide movable space for the user&#39;s neck. In some implementations, the open space formed between the left and right extension portion,  416  and  418 , respectively, may be semi-circularly shaped to suitably fit around the user&#39;s neck. As further discussed below, the left extension portion  416  and the right extension portion  418  of the child seat padding  404  may rest on top of and be removably attached to a pair of user shoulder straps ( 504   FIGS. 5A-5B ) as of the user back harness ( 500  of  FIG. 5 ) at an adjustable length. This spatial relationship of the child seat support  400  with the user back harness  500  limits the child&#39;s legs to be placed in front of the user&#39;s shoulders thus providing added security to the seated child. 
     The child safety strap  406 , comprising a first strap  426  and a second strap  428  capable of releasably engaged to each other, is adapted to securely strap the child into the child seat support  400  at an adjustable length. In one implementation, each of the first strap  426  and the second strap  428  is attached to and extended from the left edge  412  and the right edge  414  of the child back padding  402  respectively on one end, and releasably connected to each other on the other end at an adjustable length. In another implementation, the first strap  426  and the second strap  428  each may have a buckle member  430 , where the buckle member  430  can releasably engage to each other. In some implementation, an added security strap (not shown) may be attached to the left edge  412  and the right edge  414  of the child back padding, adapted for the first strap  426  and the second strap  428  of the child safety strap  406  to loop around to provide added security. 
     User Back Harness 
     As better illustrated in  FIGS. 5A-5B , the user back harness  500 A- 500 B (e.g. user back harness  106  of  FIGS. 1A-1B ) of the child carrying device, is adapted for comfortably strapping the child carrying device onto the user and may be affixed to the support frame below the child seat support. The user back harness  500 A- 500 B comprises a user back padding  502 , a pair of user shoulder straps  504 , and a load lifter mechanism  506  for detachably securing the user back harness onto the support frame. 
     The user back padding  502  forms the back portion of the user back harness and is securely and detachably fastened or hooked onto the load lifter mechanism  506  with for example a fabric strip, and the load lifter mechanism  506  is securely affixed to the lower portion (not labeled) of the support frame (not labeled). In some implementations, the user back padding  502  is padded with breathable material or fabric to provide optimum comfort and ventilation to the user while using the carrying device. 
     The pair of user shoulder straps  504  forms the front portion of the user back harness  500  and is affixed to the user back padding  502  at its upper edge (not labeled), adapted to harness the carrying device onto the user&#39;s shoulders and torso. The pair of user shoulder straps  504  further comprises a pair of child leg restraint  512  and a user sternum strap  516 . The pair of child leg restraint  512  may be adapted for removably securing the child&#39;s legs onto the pair of user shoulder straps  504 , and in one implementation, the pair of child leg restraint  512  may be releasable straps affixed to the pair of user shoulder straps  504  at its lower section (not labeled). The user sternum strap  516  may be adapted to extend across the user&#39;s chest at an adjustable length and restrain the pair of user shoulder straps  504  from sliding sideways. In some implementations, the user sternum strap  516  comprises a left sternum member  518  and a right sternum member  520 , each connected to its respective shoulder strap on one end, and releasably connected to each other on the other end. In some implementations, the pair of user shoulder straps  504  is padded with breathable material or fabric to provide optimum comfort and ventilation to the user while using the carrying device. 
     The load lifter mechanism  506  comprises a left member  508  and a right member  510  that are securely affixed to the first elongated tubular structure (not labeled) and the second elongated tubular structure (not labeled) respectively, while the user back harness  500  may be securely and detachably fastened to the left member  508  and the right member  510  of the load lifter mechanism through for example a fabric strip. 
     As better shown in  FIG. 7 , when the user is carrying a child using the carrying device, the child exerts a downward gravitational force onto the carrying device, a portion of which is transferred directly on the carrying device&#39;s shoulders, and another portion is exerted onto the support frame. The portion of the downward gravitational force exerted on the support frame can be separated into two force components. One force component travels downward along the support frame to be counter balanced by a force exerted on the support frame by the user hipbelt. Another force component is directed towards the back and is counter balanced by a pulling force exerted by the user back harness via the load lifter mechanism. The load lifter mechanism may further contain a locking mechanism so that during its locked state, the user back harness is securely and safely fastened or hooked onto the load lifter mechanism by for example a strip, and during its unlocked state, the user back harness may be detached from the load lifter mechanism. 
     The load lifter mechanism may comprise a locking mechanism so that during its locked state, the user back harness  500  is securely and safely fastened or hooked onto the load lifter mechanism  506 , and the locking mechanism is configured to prevent the user back harness  500  from unintentionally detaching from the support frame (not labeled). During the its unlocked state, the user back harness  500  may be detached from the load lifter mechanism  506  and thus be removed from the support frame. In one example, the locking mechanism may be a “J” shaped structure placed horizontally, the interior space of the tip of the “J” shape is so small that the fabric strip of the user back harness once hooked, cannot be removed without user intentionally detaching the strip from the locking mechanism. In another example, the locking mechanism may be a circular self-locking hook, where the opening faces the opposite direction of the pull, thus the strip of the user back harness once hooked and locked into the load lifter mechanism, cannot be removed without user&#39;s intentionally removing the strip from the locking mechanism. The load lifter mechanism may be configured in such a way that it may be used as a point of attachment for attaching additional weight onto the support frame via an attachment mechanism such as a self-locking hook. 
     The user back harness is secured to the support frame underneath the child seat support. The child seat padding sits on top of the pair of user shoulder straps. The left and right extension portions of the child seat padding lie on top of and may be detachably attached to the respective shoulder straps. This spatial relationship between the child seat support and the user back harness limits and restrains the child&#39;s legs to the front of the user&#39;s shoulders, providing additional security while the child is seated in the carrying device. 
     User Hipbelt 
     As better illustrated in  FIGS. 6A-6B , the example user hipbelt (e.g. user hipbelt  106  of  FIGS. 1A-1B ) of the child carrying device, secured about the user&#39;s hip or waist at an adjustable length for providing adjoining location  614  which the lower ends of the support frame rest on or attach to, and for receiving and transferring a significant portion of the carried weight from the support frame onto the user&#39;s hip or waist. The user hipbelt  600  comprises a belt  602  for securing about a user&#39;s hip or waist at adjustable length, attachment mechanism  604  for providing adjoining location which the lower ends of the support frame rest on or attach to, and a safety strap  606  for tightening and adjusting the length of the belt around the user&#39;s hip. 
     The attachment mechanism  604  comprises a left member  608  and a right member  610  affixed to the back side of the belt and is adapted to provide the adjoining location  614  which lower ends of the support frame rest on or attach to. The adjoining location which lower ends of the support frame rest on or attach to may be selectively adjusted to accommodate users of different torso length. 
     In one implementation, the left member and the right member of the attachment mechanism may each comprise multiple sockets or opening slits vertically aligned and affixed to the back side of the belt, and user of the user carrier may selectively insert the lower end of the support frame into any one of the multiple sockets or opening slits to adjust the distance or length of the support frame corresponding to the user&#39;s torso length. For example, the left member and the right member of the attachment mechanism may each contain three or multiple sockets or opening slits vertically aligned and affixed to the belt, with one socket or opening slit affixed on the higher end of the belt, one socket or opening slit vertically aligned and affixed on the lower end of the belt, and another socket or opening slit vertically aligned and affixed in between; user of the user carrier may selectively insert the lower ends of the support frame into the higher sockets or opening slits to generate a shorter distance or length of the support frame corresponding to the user&#39;s torso length to accommodate a user of a relatively shorter torso length; alternatively user of the carrying device may selectively insert the lower ends of the support frame into the lower sockets or opening slits to generate a longer distance or length of the support frame corresponding to the user&#39;s torso length to accommodate a user of a relatively longer torso length. 
     In another implementation, the left member and the right member of the attachment mechanism may each comprise location-adjustable sockets or opening slits which the lower ends of the support frame insert into to rest on or attach to, with the exact insertion point and adjoining location adjustable. For example, the left member and the right member of the attachment mechanism may contain vertical opening slits affixed to the belt with a zip-locking mechanism, and user of the user may adjust the length of the opening with the zip-locking mechanism to in order to adjust the adjoining location which the lower ends of the support frame insert into to rest on or attach to. Customizing the adjoining location to be higher on the belt may generate a shorter distance or length of the support frame corresponding to the user&#39;s torso length, to accommodate an user of shorter torso length, alternatively, customizing the adjoining location to be lower on the belt may generate a longer distance or length of the support frame corresponding to the user&#39;s torso length, to accommodate an user of longer torso length. 
     In some implementations, the left member and the right member of the attachment mechanism may contain length-adjustable extension screws which the lower ends of the support frame may screw onto and be attached to the hipbelt. In another implementation, the support frame may be configured to be extended in length, as discussed above. The extension may lengthen the support frame which is configured to further accommodate users of longer torso length. 
     The safety strap  606  is affixed to a distal portion of the belt at its front side at an adjustable length, adapted to extend across the user&#39;s abdominal and tensioning the belt about the user&#39;s hip or waist such that the provided tension secures and tightens the belt around the user&#39;s hip or waist at an adjustable length. In one implementation, the safety strap may contain a first strap and a second strap, each affixed to the respective side of the belt on one end and releasably engaged to each other on the other end. 
       FIG. 7  illustrates the example child carrier device in use by a carrier while carrying a. child. The child seat support  104  holds the carried child and is detachably secured to the top of the support frame  102 . The carrier back harness  106  straps the device onto the carrier&#39;s shoulders or torso; and the carrier hipbelt  108  secures about the carrier&#39;s hip or waist, of which lower ends of the support frame attach and rest on to. When the device is in use with a seated child, the child sits back into the child seat support and leans into the support frame, exerting a diagonally downward force. The current carrier device is configured to transfer the carried child&#39;s weight to the carrier&#39;s shoulders, torso, and hip or waist, of which the below embodiment below further discuss. 
       FIGS. 8A-8D  illustrate the child carrier device in the device&#39;s deployed state and folded state along with additional load in the form of backpack attached to the device. During the device&#39;s deployed state, the upper portion  202  extends away from the lower portion  204  of the support frame. During the device&#39;s folded state, the upper portion  202  pivots at the folding mechanism and folds toward the lower portion  204  of the support frame. 
       FIG. 9  further illustrates one implementation of the child carrier device  100 A- 100 B of  FIG. 1A-1B  in the device&#39;s deployed state with additional load in the form of a backpack attached to the device. According to an embodiment herein, the additional load in the form of the backpack is attached to the child carrying device  100 A- 100 B in the deployed state.  FIG. 10A  illustrates a back view  1000 A of the example child carrying device  100  of  FIGS. 1A-1B  in the device&#39;s deployed state. In an embodiment, the foldable support frame includes an upper portion and a lower portion joined by a folding mechanism, whereas the folding mechanism allows the upper portion of the support frame to extend away from the lower portion into a deployed state of the child carrying device and allows the upper portion to fold towards the back side to meet the lower portion into a folded state of the carrying device. This allows the carrying device to transition between a deployed state and a folded state that makes the carrying device portable, easily stored, and conserving space when the carrying device is not in use.  FIG. 10B  illustrates an additional load in the form of backpack  1000 B that can be attached to the child carrying device  100  of  FIGS. 1A-1B . In an embodiment, the present child carrying device facilitates the users to carry additional loads and an optimum carrying device is configured to accommodate additional loads easily.  FIG. 11  illustrates the side view of the child carrying device  100 A- 100 B of  FIGS. 1A-1B  in the device&#39;s folded state without any additional load attached. The easy configuration of the carrying device allows the user to transition the carrying device between a deployed state and the folded state that makes the carrying device portable, easily stored, and conserving space when the carrying device is not in use.  FIG. 12  illustrates the side view of the child carrying device  100 A- 100 B of  FIGS. 1A-1B  in the device&#39;s folded state with additional load in the form of backpack attached to the carrying device. According to an embodiment herein, the additional load in the form of the backpack is attached to the child carrying device  100 A- 100 B in the folded state.
