PATENT ABSTRACT
Disclosed is a child-carrying device designed to help a wearer carry a child, baby, infant, or toddler in their arms and accommodate a variety of holding positions. The child-carrying device can include a dual-shoulder harness, a rigid bar secured transversely between frontal strap portions of the harness, and a movable hand/wrist support assembly attached to the bar in a manner that it can freely move along the bar toward either side of the front of the wearer&#39;s rib cage, and optionally rotate about the bar. In one embodiment, to use the device, the wearer picks up a child, puts an arm under the child to support the child&#39;s weight, and then slips his hand through the hand/wrist support assembly in the form of a hand/wrist sling assembly; once in this position, only minimal exertion is required to carry the child.

PATENT DESCRIPTION
BACKGROUND 
     The present disclosure relates to an apparatus for assisting a wearer carrying a child, baby, or infant against their body. 
     Holding a child, baby, infant or toddler can be tiring. Body worn child carriers allow the wearer to tote or carry a child for extended periods of time compared to simply holding the child. Body worn child carrying devices include slings, front and rear mounted harness carriers, and hip carriers. 
     Many body worn child carriers suffer from one or more deficiencies. The carrier can be difficult to set up. Once set-up, changing the position of the child may be challenging and may require removing either the entire carrier or a portion of the carrier from the wearer. In addition, the carrier may not be comfortable for the wearer over extended periods, often creating pressure on the wearer&#39;s neck or shoulders; this is a particular problem with some sling-type carriers. The carrier may be uncomfortable to both the wearer and the child in hot weather. Also, carriers that have some degree of separation between child and wearer, for example, some front or rear mounted harness carriers, may lack the intimacy between child and wearer afforded by direct carrying. 
     SUMMARY 
     This Summary introduces a selection of concepts in simplified form that are described in more detail in the Description. The Summary is not intended to identify essential features or limit the scope of the claimed subject matter. 
     Disclosed, in several embodiments, is a device that attempts to overcome the aforementioned deficiencies described in the Background. The device can assist the wearer to support a child, baby, infant, or toddler on the wearer&#39;s arm and afford the wearer the possibility of adjusting the position of their arm along their body while holding the child. 
     The child-carrying device includes a dual-shoulder harness, a transversely mounted rigid bar, and a hand/wrist support assembly movable along the rigid bar. In one embodiment, the hand/wrist support assembly is a hand/wrist sling assembly. The shoulder harness includes a first shoulder strap portion passing over one shoulder and a second shoulder strap portion passing over the other shoulder of the wearer. The rigid bar is positioned transversely across the front of the wearer&#39;s rib cage and secured proximate to a first end portion of the rigid bar to the first shoulder strap portion and secured proximate to a second end portion of the rigid bar to the second shoulder strap portion. The rigid bar is made of a material strong enough resist substantial flexion under the weight of a child. A portion of each shoulder strap extends over the wearer&#39;s back, under their arm on the same side body and attaches to an end portion of the rigid bar. Depending on the configuration of the dual-shoulder harness, a stabilizing back strap can be attached transversely between each shoulder strap portion on the back of the wearer. The stabilizing back strap is detachably attached in order to accommodate the wearer putting on and removing the child-carrying device. The movable hand/wrist sling assembly includes a portion attached circumferentially around the rigid bar, and can freely move along the rigid bar to either side of the front rib cage, and partially rotate about the bar, thus accommodating a wide variety of holding positions. The rigid bar holds the first shoulder strap portion and the second shoulder strap portion apart, at a position proximate to the lateral position of the rigid bar. The inventor observed that this arrangement, combined with the rigid bar being mounted over the front of the wearer&#39;s rib cage, helps to distribute the weight more evenly over various positions of the hand/wrist sling along the rigid bar while supporting the child. To use the device, the wearer picks up the child, puts an arm under the child to support the child&#39;s weight, and then slips his hand through the strap; once in this position, only minimal exertion is required to carry the child. 
     In another embodiment, the shoulder strap portions are secured to each other on the front of the wearer, in part, by a transverse front strap positioned below the wearer&#39;s armpits over the front of the wearer&#39;s rib cage. The transverse front strap can be detachably attached, for example, by a detachable buckle, ladder lock, or bar slide. 
     In a further embodiment, the shoulder strap portions can form a cross-pattern across the wearer&#39;s back in order to provide additional stability. The bar can be detachably attached to the shoulder harness on at least one end in order to accommodate the wearer putting on and removing the child-carrying device. 
     In another embodiment, the rigid bar includes an aperture defining a slot along the length of the bar. A portion of the hand/wrist sling assembly includes a flanged attachment. The flanged attachment, in combination with the slot, forms a joint that allows the hand/wrist sling assembly to move freely along the bar to either side of the front of the wearer&#39;s rib cage, thus accommodating a wide variety of holding positions of the child. The portion of the flanged attachment that engages the bar can be shaped to also partially rotate about the bar allowing the wearer additional freedom of movement. 
     In a further embodiment, the hand/wrist support assembly includes a hand grip with either an integral or attached hand support. The hand/wrist support assembly is movable along the rigid bar.

     The following terms are defined here for clarity and convenience. The term child is used collectively to mean infant, baby, toddler, or young child. Child carrier is an equivalent term for a child carrying device or a child carrying apparatus. The terms “first” and “second” are used to distinguish similar portions or parts of the described structure, however, they do not imply any particular order or preference. The use of the terms “left” or “right” in the description that follows refer to the left and right side from the wearer&#39;s perspective as depicted in drawings. Similarly, the terms “up” and “down” that follow refer to the orientation of various elements in relation to the orientation of the wearer&#39;s body. These terms are meant to aid in understanding the drawings and not meant to limit the claimed invention to a particular number or order of parts, a particular side of the wearer, or a particular direction. In addition, the term lateral, for the purposes of this disclosure, means tending toward one side of the wearer&#39;s body. For the purpose of this disclosure, a hand/wrist support assembly refers to a support assembly for supporting a hand, wrist, or upper forearm, or for supporting the combination of a hand and a wrist, the combination of a wrist and a upper forearm, or the combination of a hand, a wrist, and an upper forearm. The hand/wrist support assembly can be a hand/wrist sling assembly, as defined below, but is not limited to such. For the purpose of this disclosure, a hand/wrist sling assembly refers to a sling assembly for supporting a hand, wrist, or upper forearm, or for supporting the combination of a hand and a wrist, the combination of a wrist and a upper forearm, or the combination of a hand, a wrist, and an upper forearm. For the purpose of this disclosure, a “dual-shoulder harness” is used to collectively describe a strapped harness, that when worn is supported by both shoulders of the wearer and is configured as a restrained support. 
     The description that follows is made with reference to figures, where like numerals refer to like elements throughout the several views.  FIGS. 1 ,  2 , and  3  illustrate an embodiment of a child carrier  100  shown worn by a wearer  102  holding a child  104 . The child carrier  100  includes a hand/wrist support assembly in the form of a hand/wrist sling assembly  106 . The hand/wrist sling assembly  106  is slidable along and rotatable about a rigid bar  108 . The rigid bar  108  is held transversely at the front of the wearer&#39;s rib cage between and by a first shoulder strap portion  110  and a second shoulder strap portion  112 . The rigid bar  108  holds the first shoulder strap portion  110  and the second shoulder strap portion  112  apart, at a position proximate to the end portions of the rigid bar  108 . The first shoulder strap portion  110  and the second shoulder strap portion  112  form a portion of a dual-shoulder harness. The first shoulder strap portion  110  and the second shoulder strap portion  112  are attached to the top and side of a corresponding end of the rigid bar  108 . The first shoulder strap portion  110  and the second shoulder strap portion  112  are illustrated as being substantially flat and cushioned. Alternatively, the first shoulder strap portion  110  and the second shoulder strap portion  112  can also be tubular or rounded, and either cushioned or not cushioned. Starting from the topside of rigid bar  108 , the first shoulder strap portion  110  and the second shoulder strap portion  112  extends laterally over the front of the wearer&#39;s ribcage, over a shoulder, and under an arm corresponding to the shoulder and attaching to the side of the rigid bar  108  corresponding to the topside attachment. 
     The hand/wrist sling assembly  106  is shown in  FIGS. 1 ,  2 , and  3  facilitating the wearer  102  with holding the child  104  in various positions. In  FIG. 1 , the wearer  102  is shown supporting the child  104  with their right arm. The hand/wrist sling assembly  106  supports the wearer&#39;s right hand and wrist along the center position of the rigid bar  108 . In  FIG. 2 , the child  104  is supported by the wearer&#39;s right arm, but with the hand/wrist sling assembly  106  slid over to the right most position of the rigid bar  108 . 
     In  FIG. 3 , the wearer  102  is supporting the child  104  with their left arm. The hand/wrist sling assembly  106  supports the wearer&#39;s left hand and wrist along the center position of the rigid bar  108 . Switching from a right arm to left arm holding position, and vice versa, does not require removal or disassembly of the child carrier  100  from the wearer  102 . The wearer  102  can simply remove one hand from the hand/wrist sling assembly  106  and place the other hand into the hand/wrist sling assembly  106 . 
     Throughout this disclosure, a strap is defined as a piece of pliant or flexible material suitable for holding, securing or binding. For example, straps and strap portions for the dual-shoulder harness or sling assembly can be made of nylon, polyester, polypropylene, cotton, leather, or hemp. These can be formed into flat, tubular, or rounded shapes. The straps can be solid, hollow or layered, and non-woven or woven. Hollow or layered straps can be filled with a cushioning material. These examples are not meant to limit the claimed invention, but are provided as examples of suitable materials or suitable fabrics. Those skilled in the art will readily recognize other equivalent materials or combination of materials of suitable strength, shape, and flexibility, for dual-shoulder strap harness and for a weight bearing sling assembly. 
     For further clarity,  FIGS. 4 ,  5 , and  6 , illustrate the child carrier  100  worn by a wearer  102  without the child  104  of  FIGS. 1-3 . Referring to  FIGS. 4 ,  5 , and  6 , the rigid bar  108  of  FIGS. 4 and 6  is supported between two frontal portions of the dual-shoulder harness. Each frontal portion is illustrated approximately lateral along the front of the wearer&#39;s body from the respective shoulder of the wearer. Specifically, the rigid bar  108  of  FIGS. 4 and 6  is supported on the top and left side of the wearer  102  by the first shoulder strap portion  110 . The first shoulder strap portion  110  is shown extending over the wearer&#39;s left shoulder and under their left arm. Similarly, the rigid bar  108  of  FIGS. 4 and 6  is supported on the top and right side of the wearer  102  by the second shoulder strap portion  112 . The second shoulder strap portion  112  is shown extending over the wearer&#39;s right shoulder and under their right arm. The rigid bar  108  can be covered with and enclosed by fabric or other material, for example, nylon, polypropylene, or polyester. A cushioning filler such as Ethylene vinyl acetate (EVA) foam, can optionally surround the bar within the fabric envelope. 
       FIG. 4  illustrates an example of how the first shoulder strap portion  110  and the second shoulder strap portion  112  of the dual-shoulder harness can be secured to the rigid bar  108 . A first D-ring  114  secures a first end portion  116  of the first shoulder strap portion  110  to the rigid bar  108 . The first end portion  116  can be sewn, heat bonded, glued, riveted, hook and loop fastened, or otherwise secured to itself to form the loop. The other end of the first D-ring  114  is secured to an attachment portion in the form of a first attachment loop  118  that extends upward from near the left end of the fabric covering of the rigid bar  108 .

The hand/wrist sling assembly  603 , with the exception of the hanging strap attachment portion, is substantially as the hand/wrist sling assembly  106  described for  FIG. 7 . The rigid bar  602  of  FIGS. 24A-C  is hollow. The rigid bar  602  includes a slot  604  along its length. A flanged attachment  606 , such as a flanged stud button, is attached to an end portion of the hanging strap  608 , the hanging strap  608  engages the hand/wrist sling assembly  603 . The flanged attachment  606  and hanging strap  608  are cooperatively configured so that the hand/wrist sling assembly  603  is slidable along the rigid bar  602 . 
       FIG. 24B  shows a detail side view of the end portion of the hanging strap  608 . The flanged attachment  606 , can be a stud button with a flanged portion  610 , a shank  612 , and a stud  614 . The stud  614  and the shank  612  in combination hold the flanged attachment  606  to the hanging strap  608  of  FIG. 24A .  FIG. 24C  illustrates a cross sectional end view of the rigid bar  602  engaged with the flanged attachment  606  and hanging strap  608 . The flanged portion  610  is larger than the slot  604  but the shank  612  is smaller than the slot  604 . This arrangement allows the flanged attachment  606  to captively slide along the length of the bar as well as rotate or swing as illustrated by arrows in  FIG. 24A . 
     In one embodiment, the rigid bar  602  includes the slot  604  extending across the entire length of the rigid bar  602 . The shank  612  of the flanged attachment  606  is slid into one end of the rigid bar  602 . Referring to  FIG. 24A , removable or permanently affixed end caps prevent the flanged attachment  606 , and thus the hand/wrist sling assembly  603 , from coming off the rigid bar  602 . End caps can be removably or permanently affixed, for example, end caps can be plastic inserts, fabricated from hook and loop material. Alternatively, the end caps can be fabricated from a fabric that is secured to rigid bar  602 , for example, by gluing, riveting, heat bonding. The rigid bar  602  can be detachably attached to the first shoulder strap portion  304  and the second shoulder strap portion  306  as previously described for  FIGS. 16-21 .

The hand/wrist pad  702  can include a filler such as EVA foam, cotton, polyester fiber, or other cushioning material. The double bar slide  706  can be used to adjust the length of the strap and independently adjust a loop around the rigid bar  108 . A side release, top release or cam buckle can be substituted for the double bar slide  706 . In addition, a single bar slide can be substituted if only the strap&#39;s length adjustment is desired. Alternatively, the strap  704  can be fashioned into a loop by sewing, heat bonding, gluing, riveting, or otherwise bonding the strap to itself. A hook and loop fastener, for example, sold under the brand name Velcro, cab be used to removably secure the strap  704  to itself. The strap can also be similarly fashioned into two loops, a smaller loop that wraps around the rigid bar  108 , and a larger loop that cradles the hand/wrist pad  702 . While  FIG. 25  illustrates the hand/wrist sling assembly  700  in combination with the harness assembly and the rigid bar  108  of  FIG. 16 , it should be understood by the reader, that the hand/wrist sling assembly  700  can be implemented in other embodiments, for example, the embodiments of  FIGS. 4 , and  10 ,  16 , and  22 , and can be adapted to be implemented in the embodiment of  FIG. 24A . 
       FIG. 27  illustrates a hand/wrist sling assembly  800  with a loop  802  for sliding along the rigid bar that includes a friction insert  804  within the loop  802 . Suitable materials for the friction insert  804  include, but are not limited to, elastomers such as a synthetic or natural rubber. The friction insert  804  can be made of a material that has the property of slowing down or stopping the sliding of the hand/wrist sling assembly  800  along the bar when sufficient downward pressure is applied, typically, the downward pressure from the weight of holding a child. While the loop  802  is shown adjustable by double bar slide  806 , the insert can be easily adapted into the other disclosed hand/wrist slings, for example, the hand/wrist sling assembly  106  of  FIG. 7 , the hand/wrist sling assembly  302  of  FIG. 17 , or the hand/wrist sling assembly  700  of  FIG. 25 . The friction insert  804  can be secured to the loop  802  by sewing, gluing, heat bonding, or by a hook and loop fastener. Alternatively, the friction insert  804  can surround the loop  802 . The friction insert  804  can also be impregnated directly into the fabric of the loop  802 .
