The present disclosure relates to child carriers. More particularly, the present disclosure relates to a child carrier that is adaptable to allow a child enhanced freedom of movement. The present disclosure also relates to child carriers that provide easy height and width adjustment.
Soft structured child carriers use stitching and fabrics to provide structure rather than a rigid frame. Such carriers have become increasingly popular for carrying infants and toddlers because they afford the wearer freedom of hand and arm movement while carrying a child. On the other hand, some soft structure carriers unduly limit the leg and arm movement of the child. Moreover, some soft structure carriers limit the child to be being carried in a single position and orientation, such as inward-facing, front-carry.
A number of some soft-structured carriers support a child in a non-ergonomic upright position with the child's legs hanging down and the base of the child's spine supporting the child's bodyweight. This position is not optimal for the child because it can unduly limit curvature of the spine and put stress on the infant's sacrum. This can cause the child's pelvis to tilt backward limiting leg and hip movement, which may impede healthy development of the infant's pelvis.
Moreover, soft structured carriers are often designed for a very limited age, weight and size of child and make compromises regarding the shape of the carrier to accommodate a range of ages. A carrier designed for infants or younger babies may not accommodate a child as the child grows into toddlerhood because the seat and back support portions of the carrier will become too small. On the other hand, a carrier designed for older children may not properly support an infant.
One solution to addressing the limited size range of a carrier is the use of a specially designed “infant insert.” In general, an infant insert is an accessory that incorporates additional padding and structure and makes it possible to carry a small infant in a carrier that would not otherwise properly support the infant. However, not all carriers support the use of infant inserts. Moreover, depending on design, infant inserts may be cumbersome, non-intuitive, and easily lost. In particular, the use of a separate infant insert may require that parents keep track of two separate devices and may significantly increase the difficulty of configuring the carrier for a wearer, the wearing of the carrier, or the ingress and egress of a child to the carrier.
Due to the foregoing issues, parents may opt for changing carriers as the child ages.
One embodiment of the present disclosure comprises a soft-structured child carrier that includes a waistband, a body panel having a bottom end attached to a bottom portion of the waistband, a first shoulder strap adapted to lift a first top corner of the body panel, a second shoulder strap adapted to lift a second top corner of the body panel, a first shoulder strap attachment panel attached to the interior side of the body panel away from the side edges of the body panel and a second shoulder strap attachment panel attached to the interior side of the body panel and away from the side edges of the body panel. The first shoulder strap attachment panel provides a first flap that is movable away from the interior surface of the body panel and includes a first lower attachment point for the first shoulder strap. The second shoulder strap attachment panel provides a second flap that is movable away from the interior surface of the body panel and includes a second lower attachment point for the second shoulder strap.
More particularly, according to one embodiment, the first shoulder strap attachment panel is attached to the body panel to the first side of the body panel's lateral centerline and closer to the lateral centerline than to the first side edge. Further, according to one embodiment, the second side edge is attached to the body panel to a second side of the body panel's lateral centerline and closer to the lateral centerline than to the second side edge.
According to one aspect of the present disclosure, the first shoulder strap attachment panel is adapted to protect a child carried in the child carrier from the first shoulder strap and the second shoulder strap attachment panel is adapted to protect the child from the second shoulder strap. For example, in one embodiment, the first lower attachment point is disposed on the exterior side of the first shoulder strap attachment panel exterior side and the second lower attachment point is disposed on the exterior side of the second shoulder strap attachment panel exterior side.
According to one embodiment, the child carrier includes a webbing tab attached to the first shoulder strap attachment panel at the first lower attachment point. A first buckle member is attached to the webbing tab. The first buckle member is adapted to connect to a respective buckle member on a portion the first shoulder strap. According to one embodiment, the child carrier further includes a second webbing tab attached to the second shoulder strap attachment panel at the second lower attachment point. A second buckle member is attached to the second webbing tab. The second buckle member is adapted to connect to a respective buckle member on a portion of the second shoulder strap. In one embodiment, the first shoulder strap includes a first shoulder strap portion extending from a first top corner of the body panel to a third buckle member, the third buckle member adapted to connect to the first buckle member, and the second shoulder strap comprises a second shoulder strap portion extending from the second top corner to a fourth buckle member, the fourth buckle member adapted to connect to the second buckle member.
According to one embodiment, the first shoulder strap attachment panel is adapted to form a first leg opening for a child when the first shoulder strap attachment panel is pulled away from the body panel by the first shoulder strap and the second shoulder strap attachment panel is adapted to form a second leg opening for the child when the second shoulder strap attachment panel is pulled away from the body panel by the second shoulder strap.
According to one embodiment, the body panel has a first body panel width at the bottom end of the body panel and a second body panel width away from the waistband, the second body panel width being less than the first body panel width. The first lower attachment point and second lower attachment point may be farther away from the bottom end of the body panel than the second body panel width. The second body panel width may be a minimum body panel width.
According to one aspect of the present disclosure, the body panel is adapted to form a bucket seat. The body panel can include a foldable portion that is adapted to fold between the waistband and a wearer to reduce an effective height of the body panel and the base width of the bucket seat. According to one embodiment, the width of the body panel narrows along the foldable portion, moving away from the waistband.
The body panel can be configurable in a plurality of configurations relative to the waistband. According to one embodiment the plurality of configurations include i) a first configuration in which the body panel is lifted up by the first shoulder strap and second shoulder strap to the exterior side of the waistband and is not folded between the waistband and the wearer, the first configuration forming a first bucket seat with a first base width; and ii) a second configuration in which a portion of the body panel is folded between the waistband and the wearer and the body panel exits from behind the waistband at the top edge of the waistband, the second configuration forming a second bucket seat with a second base width. According to one embodiment, the body panel has a first body panel width at the bottom end of the body panel and a second body panel width away from the waistband such that the first base width is equal to the first body panel width and the second base width is equal to the second body panel width. In some embodiments, the first configuration is adapted to support a larger child in a first spread squat position and the second configuration is adapted to support a smaller child in a send spread squat position.
For a better understanding of these and other objects of the invention, reference will be made to the following detailed description of the invention which is to be read in association with the accompanying drawings, wherein:
Child carriers and related methods and the various features and advantageous details thereof are explained more fully with reference to the nonlimiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known starting materials, processing techniques, components and equipment are omitted so as not to unnecessarily obscure the invention in detail. It should be understood, however, that the detailed description and the specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only and not by way of limitation. Various substitutions, modifications, additions and/or rearrangements within the spirit and/or scope of the underlying inventive concept will become apparent to those skilled in the art from this disclosure.
One embodiment comprises a carrier that allows for less tension on the body panel (e.g., front panel), particularly the side edges of the body panel, by having the side/lower shoulder strap attachment points to the interior of the body panel away from the side edges of the body panel. The reduced tension allows for more freedom of movement for the child.
According to one embodiment, a carrier may include shoulder strap attachment panels that provide shoulder strap attachment points. The shoulder strap attachment panels are attached to the interior of the body panel of the soft structured carrier, away from the side edges, thereby lessening tension on the side edges of the body panel. Further the shoulder strap attachment point may be on the exterior side of the shoulder strap attachment panels such that the shoulder strap attachment panels protects the child in the child carrying area from the shoulder straps (e.g., protects the child from coarse material or buckles that are part of the shoulder strap).
In addition, or in the alternative, a carrier may include features that allow the carrier to be reconfigured to accommodate a range of child ages/sizes. One embodiment comprises a carrier that allows for easy height and width adjustment by adjusting how the body panel is lifted and/or folded relative to the waistband (e.g., waist belt). According to one embodiment, the body panel is adapted so that it can be pulled up and folded between the waistband and the wearer's torso to shorten the body panel and narrow the body panel. In another mode of use, the body panel can be pulled up to the front of the waistband to lengthen the body panel and widen the body panel.
According to one embodiment, the body panel may be sewn or otherwise attached to the bottom of a waistband (where the “bottom” of the waistband herein refers to the bottom of the waistband in the orientation in which the waistband is intended to be worn during use). The body panel may be adapted to be pulled up behind the waistband and folded between the waistband and the wearer's stomach to achieve a configuration in which the portion of the body panel that supports the child is shorter and has narrower seat base—in this case, making the carrier body panel come out from between the wearer and the top edge of the waistband thus shortening the carrier's effective height by the waistband height measurement. In some embodiments, the body panel may be folded multiple times behind the waistband. The configuration can be adapted to ergonomically seat a smaller child. According to one embodiment, the carrier body panel also releases from the waistband at the narrowest point of the body panel in this configuration (e.g., the body panel emerges from between the wearer and waistband with the narrowest width of the body panel at the top edge of the waistband). In this configuration, the baby/infant is seated above the waistband as opposed to below the waistband in the second configuration.
In another embodiment, the body panel may be adapted to be pulled up between a panel retaining strap and the front of the waistband to achieve a configuration in which the portion of the body panel that supports the child is shorter and has narrower seat base—in this case, making the carrier body panel come out from between the waistband and the top edge of the panel retaining strap thus shortening the carrier's effective height by the distance between the bottom of the waistband and the top of the panel retaining strap. In some embodiments, the body panel may be folded multiple times between the waistband and panel retaining strap. The configuration can be adapted to ergonomically seat a smaller child. According to one embodiment, the carrier body panel emerges from between the waistband and the top of the panel retaining strap with the narrowest width of the body panel at the top edge of the panel retaining strap.
The body panel can also be lifted up to the front of the waistband to achieve another configuration in which the portion of the body panel available to support the child is longer and the seat base is wider. The second configuration can be adapted to ergonomically support a larger child.
The carrier can be adapted to carry a child in a manner that supports the child and maintains the child's pelvis and thighs in a preferred ergonomic position through a range of ages. In particular, embodiments described herein provide carriers that support the child's bottom, pelvis and thighs in a desired position. Embodiments described herein also allow a child to be carried in an inward facing orientation (facing the wearer) or an outward facing orientation (facing away from the wearer). The adjustable child carrier can be configured to accommodate children of a wide range of sizes. For example, embodiments of a child carrier as disclosed herein may provide an adjustable child carrier usable with newborn children (infant) (e.g., around 7 pounds) and additionally with children all the way to up to around 30 pounds or more.
One embodiment comprises an adjustable freedom-of-movement, simple construction carrier that ergonomically and easily supports a child through a range of ages, while fitting comfortably on a wide range of body types. According to one embodiment, the carrier allows for (1) easy height and width adjustment by adjusting how the body panel is lifted and/or folded relative to the waistband and/or (2) less tension on the body panel, particularly the side edges of the body panel.
Waistband 110 comprises a band of one or more sections to encircle a wearer and a fastening mechanism, such as a buckle, snaps, ties or other mechanism, to fasten the band. In the illustrated embodiment, waistband 110 comprises a padded section 112, strap sections 114 sewn or otherwise attached to padded sections 112 and complementary buckle members 116 attached to strap sections 114. Padded section 112 is adapted to encircle the hips of the wearer when the carrier is worn. Padded section 112 can be padded, for example, with a semi-rigid material and covered with fabric. This material can be stiff foam, or any other appropriate material known or convenient, including closed cell foams such as ethylene-vinyl acetate (also known as EVA). The semi-rigid material and the wide shape of the padded section 112 serves to distribute the weight of the child around waist of the wearer. Limited adjustment of the waist belt length is provided by an adjusting loop formed at one of the buckle members. In another embodiment, the waistband comprises a relatively narrow waist belt sized to fit entirely around a user's waist and a belt pad disposed along a portion of the belt to provide the padded section 112.
Body panel assembly 120 is adapted to form a child carrying area in cooperation with the wearer's torso. To this end, body panel assembly 120 comprises a body panel 122 (e.g., a front panel) that may be adapted to form a curved shape that supports the legs, hips, posterior and upper body of the child. The body panel 122 includes an end proximate to waistband 120 (referred to herein as the “bottom end”), two opposed side edges 126 and a top end 127. The bottom end of body panel 122 is sewn or otherwise attached to the bottom portion of waistband 110, for example at or near the bottom edge of padded section 112. For example, the bottom end is stitched securely into the bottom section of the waistband 110. Moving away from waistband 110, the outer side edges 126 of body panel 122 are shaped such that the body panel width (indicated generally at 128) changes along at least a portion of the body panel 122. According to one embodiment, the outer side edges 126 curve or otherwise taper laterally inward such that to a minimum body panel width and then curve or otherwise taper latterly outward again. According to one embodiment, the minimum body panel width occurs at a distance from the bottom end of body panel 122. The minimum body panel width, location of the minimum body panel width and the shape of side edges 126 can be selected to create desired carrier shapes in the multiple configurations.
In general, body panel 122, at least proximate to waistband 110, may be formed of an easily foldable textile construction. Body panel 122 may be formed from one or more panels joined together. For example, body panel 122 may include a center panel and side panels. Body panel 122 can be formed of a single material or multiple materials. For example, body panel 122 may be formed with an interior layer selected for comfort against a child's skin and an outer layer selected for breathability, fashion, stain resistance, etc. In some embodiments, body panel 122 or other portions of carrier 100 may incorporate engineered knitting to shape the carrier. For example, the center portion of the body panel may be shaped using engineered knitting. In some embodiments, the entire body panel 122 is shaped using seamless engineered knitting. In such an embodiment, body panel 122 can be constructed such that there are no seams or darts on the body of the carrier and all body shape is achieved through knitting.
According to one embodiment, each shoulder strap 160 is sewn or otherwise coupled to body panel assembly 120 at a respective first point, which may be referred to as an upper attachment point because it is an upper attachment point when the carrier is in use, and second point, which may be referred to as a lower attachment point or side attachment point. The shoulder straps 160 are adapted to lift body panel assembly 120 and pull body panel assembly 120 toward the wearer to create the child carrying area. In the embodiment illustrated, each shoulder strap 160 has a portion that extends from an upper corner or portion of body panel 122 to a buckle member 164. The buckle member 164 connects to a respective buckle member 142, which is in turn attached to a webbing tab 140.
According to one embodiment, the shoulder straps 160 may have an expandable width. For example, shoulder straps 160 may include material that is folded over to form a slit 162 or other opening that can open/widen to allow the shoulder straps to widen.
Body panel assembly 120 comprises wings, flaps or other mechanism to direct tension or force from the lower shoulder strap attachment points away from the side edge 126, thus reducing the tension on outer edges 126 of body panel 122 during use and allowing greater freedom of movement for the child. In the illustrated embodiment, body panel assembly 120 comprises pair of shoulder strap attachment panels 130 that are sewn or otherwise attached to the interior of the body panel 122. Shoulder strap attachment panels 130 provide lower attachment points for the shoulder straps 160 and are adapted so that force or tension at the lower attachment points is transferred to body panel 122 away from side edges 126.
According to one embodiment, each shoulder strap attachment panel 130 is sewn or otherwise coupled to body panel 122 along an inner side edge 132 to body panel 122 at a position that is away from the outer side edges 126 of body panel 122. Even more particularly, according to one embodiment, the inner side edges 132 are coupled to the body panel 122 closer to the lateral centerline of the body panel than to the respective body panel side edge 126. While the shoulder strap attachment panels 130 of the illustrated embodiment are attached to body panel 122 away from the lateral centerline of body panel 122, the shoulder strap attachment panels 130 may be sewn or otherwise attached to body panel 122 at the lateral centerline in other embodiments.
Shoulder strap attachment panels 130 provide wings or flaps. More particularly, a portion of each shoulder strap attachment panel 130 is free to be pulled (e.g., swing) away from body panel 122. In the illustrated embodiment, the bottom edges, outer side edges and top edges of shoulder strap attachment panels 130 are free and thus shoulder strap attachment panels 130 may swing or otherwise be pulled away from away from body panel 122 (e.g., swing away from body panel 122).
According to one embodiment, all or a portion of each shoulder strap attachment panel 130 may have a width such that, when the carrier is spread open, the width of the carrier at the shoulder strap attachment panels 130 is greater than the width of the body panel 122 at the same distance from the bottom end of the body panel 122. In the illustrated embodiment, the top portions of the shoulder strap attachment panels 130 (the portions proximate to the respective top edges and distal from waistband 110) have a sufficient length that they can extend past the closest body panel side edges 126. The shoulder strap attachment panels 130 are shaped to provide leg openings for a child's legs when shoulder strap attachment panels 130 are pulled away from body panel 122 by the shoulder straps.
Each shoulder strap attachment panel 130 includes an attachment point for a shoulder strap. In the illustrated embodiment, for example, each shoulder strap attachment panel 130 includes an attachment point at which a shoulder strap webbing attachment tab 140 is sewn or otherwise coupled to the exterior side of each shoulder strap attachment panel 130 (the attachment in the illustrated embodiment is partially obscured by a covering material). Buckle members 142 are attached to the shoulder strap webbing attachment tabs 140 so that shoulder straps can be connected to strap webbing attachment tabs 140 with complementary buckle members 164. The shoulder strap attachment point on each shoulder strap attachment panel 130—that is, the point where the shoulder strap webbing attachment tab 140 is sewn or otherwise coupled to the shoulder strap attachment panel 130 in the illustrated embodiment—is located on a portion of the shoulder strap attachment panel 130 that can swing or otherwise move away from body panel 122. In some embodiments, the shoulder strap attachment point on each shoulder strap attachment panel 130 is latterly inboard of the respective side edge 126. Furthermore, the shoulder strap side attachment point on each shoulder strap attachment panel 130 is located so that it is farther away from the bottom edge of body panel 122 than the narrowest portion of body panel 122. In other embodiments, the attachment point may be located outboard of the respective side edge 126 and/or in another location relative to the narrowest part of the body panel 122.
It will be appreciated that shoulder strap attachment panels 130 are provided by way of example and other shapes of shoulder strap attachment panels may be used. Moreover, while shoulder strap attachment panels 130 are illustrated as separate panels, shoulder strap attachment panels 130 may be portions of a single panel that is sewn or otherwise attached to body panel 122 to form shoulder strap attachment panels. Further, shoulder strap attachment panels 130 may have a variety of form factors.
Moreover, the force or tension from a lower shoulder strap attachment point may be directed away from the side edges 126 of a body panel 122 by other mechanisms. For example, in another embodiment the second end of each shoulder strap (e.g., shoulder strap webbing attachment tabs 140 or other shoulder strap portion) may be sewn or otherwise attached directly to the interior of a body panel 122 away from the side edges 126. Thus, it will be appreciated that a variety of mechanisms may be used to reduce tension on the side edges of the body panel. Moreover, various mechanism to reduce tension on the side edges of a panel, such as shoulder strap attachment panels, can be used with a variety of carrier designs. By way of example, attachment panels of various forms or other mechanisms to reduce tension at the side edges of the body panel may be used with a variety of carrier designs, including carriers in which the body panel height and width is adjustable and designs in which the body panel height and width is not adjustable.
Carrier 100 can be reconfigured to accommodate a child through a range of ages/sizes.
In the second configuration, the base edge of the seat proximate to the waistband is not fixed to the waistband. Consequently, the side edges of the carrier body panel 122 can be pushed together at the seat base to further narrow the base width of carrier.
As the child develops, the carrier can be reconfigured to accommodate the child.
In one embodiment, the carrier can be adapted to support the child in a position with the child's femur approximately 90° to 120° (or other elevated position) from the coronal plane and to position the child's knees with an amount of spreading. The amount of spreading may depend on the developmental stage of the child and orientation with a newborn having less than 30°, then approximately 30°, then approximately 35°-40° and so on so, such that the final spread is approximately 40°-45°, though other amounts of spreading may be achieved including (e.g., for example approximately 55°. In one embodiment, the spreading may be at least 20° degrees from the median plane. The child's weight can be distributed across the child's bottom, thighs and back so that the sacrum does not bear too much weight and the child can rest with a more naturally curved “C” spine in a spread squat position that is believed to be better for pelvic development. It can be noted, however, that the child can be positioned in any comfortable position, preferably emphasizing a supportive posture rather than a posture where the child is primarily sitting on his or her sacrum.
Carrier 100 is adapted to provide a supportive bucket seat with a generally concave (e.g., “C” shape) inner profile. The minimum body panel width, position of the minimum body panel width and the shape of the side edges 126 can be selected such that body panel 122 can create multiple bucket seat configurations to ergonomically support a child through a range of ages/sizes and in multiple seating orientations. The side panels can be shaped so that the outer edge 126 is shorter than the inside/center edge of the side panel. In use, the outer side edges 126 can be higher than the center of the seat and spaced such that they pass under and around the child's thighs at a distance from the child's hips to lift the child's legs (e.g., above the knee). In some embodiments, additional support or padding may be placed proximate to edges 126 at the areas that will support a child's thighs.
According to one embodiment, carrier 100 is adapted so that the bucket seat formed in the narrower base width configuration can ergonomically support newborns and infants. Configured according to such a setting, the carrier may be adapted for placement of a child in a child carrying area of the child carrier with the infant's knees raised. In one embodiment, when adjusted to accommodate an infant, the carrier is adapted to support the infant in a position with the infant's femur at an angle of 90-120 degrees from the coronal plane. Additionally, the carrier can be adapted to support the infant in a position with the infant's knees at 45-60 degrees from the median plane. In particular embodiments, the carrier can be adapted to promote a spread-squat-position (also known as the “frog leg”, “frog”, “squat spread” or “M” position) in which the flexion at the hip joint is at least 90° and in some cases is 110° to 120° from the coronal plane with the knees spread as appropriate for the developmental stage. In one embodiment, the spreading may be at least 20° degrees from the median plane. The child's weight can be distributed across the child's bottom, thighs and back so that the sacrum does not bear too much weight and the child can rest with a more naturally curved “C” spine in a spread squat position that is believed to be better for pelvic development. It can be noted, however, that the child can be positioned in any comfortable position, preferably emphasizing a supportive posture rather than a posture where the child is primarily sitting on his or her sacrum.
In another configuration (e.g., a wider base configuration), the carrier can be adapted to support the larger child in a spread squat position with the child's femur approximately 90° to 120° (or other elevated position) from the coronal plane and to position the child's knees with an amount of spreading. The amount of spreading may depend on the developmental stage of the child and orientation of the child in the carrier. In one embodiment, the spreading may be at least 20° degrees from the median plane. The child's weight can be distributed across the child's bottom, thighs and back so that the sacrum does not bear too much weight. Further, the carrier can support the child's spine with a level of curvature appropriate of the child's developmental stage. It can be noted, however, that the child can be positioned in any comfortable position, preferably emphasizing a supportive posture rather than a posture where the child is primarily sitting on his or her sacrum.
Carrier 100 may be adjusted to provide ergonomic support for the child regardless of the size of the child through a supported range. In accordance with one embodiment, carrier 100 can be set for an infant with a narrower seat configuration. In this configuration, the bucket seat will be at its deepest with higher walls at the thigh support areas, lifting the child's thighs and knees to a greater angle and into a spread squat position appropriate for that size child.
Similarly, carrier 100 can be set for a larger child with the seat at its widest setting. In this configuration, the bucket seat may be at its shallowest depth with lower walls at the thigh support areas, lifting the child's thighs and knees to a lesser angle and into a spread squat position appropriate for a larger sized child. For example,
Thus, the adjustable bucket seat is configurable in a plurality of configurations having different seat bucket depths and seat bucket widths. The different configurations can be adapted to support a child in a corresponding size range in a spread squat position. For example, in one embodiment, bucket seat can have a configuration adapted to ergonomically carry a child of 20-24 inches (generally corresponding to an infant of 0-3 months and over 7 pounds) in a spread squat position appropriate for the infant without requiring an infant insert. Furthermore, the carrier can have another configuration adapted to ergonomically carry a larger child in a spread squat position appropriate for that child's size. The configuration for carrying newborns/infants can correspond to the seat width being at the narrowest setting and the configuration for carrying larger children can correspond to the seat width being at a widest setting (shallowest bucket seat) (a toddler mode). It can be noted that the ranges provided above are provided by way of example and not limitation. Furthermore, the seat may have other configurations.
The user can thus adjust carrier 100 to support the child in an ergonomic spread squat position appropriate for the weight or size of the child with the child's pelvis, bottom and thighs all being supported. The child's weight can be supported so that the child is squatting in the seat rather than sitting with the child's weight primarily on the sacrum. The child can be supported with the knees higher than the bottom, in some cases higher than 90 degrees. The carrier can be adjusted to form a sling or pouch that is wider than the child's hips.
Carrier 100 can also provide enhanced freedom of movement. Turning to
As shown in
It can be noted that panel 122 is provided by way of example and panel 122 can have a variety of form factors. Moreover, a carrier with height and/or width adjustment according to the teachings of the present disclosure may have a variety of shoulder strap configurations. In one embodiment, for example, the lower/side attachment shoulder strap attachment points may occur on body panel 122 at or proximate to the side edges 126. Such an embodiment, while possibly exhibiting increased tension at the side edges, would still provide the advantage of easy height/width adjustment to ergonomically support a child through a range of ages/sizes.
Moreover, in some embodiments carrier 100 includes a retaining strap on the front of the waistband so that the bottom portion of body panel 122 can be folded between the waistband and retaining strap rather than between the waistband and the wearer. Other retaining mechanisms, such as snaps, retaining loops may also be used to maintain body panel 122 in a folded configuration.
Waistband 210 comprises a band of one or more sections to encircle a wearer and a fastening mechanism, such as a buckle, snaps, ties or other mechanism, to fasten the band. In the illustrated embodiment, waistband 210 comprises a padded section 212, strap sections 214 sewn or otherwise attached to padded sections 212 and complementary buckle members 216 attached to strap sections 214. Padded section 212 is adapted to encircle the hips of the wearer when the carrier is worn. Padded section 212 can be padded, for example, with a semi-rigid material and covered with fabric. This material can be stiff foam, or any other appropriate material known or convenient, including closed cell foams such as ethylene-vinyl acetate (also known as EVA). The semi-rigid material and the wide shape of the padded section 212 serves to distribute the weight of the child around waist of the wearer. Limited adjustment of the waist belt length is provided by an adjusting loop formed at one of the buckle members. In another embodiment, the waistband comprises a relatively narrow waist belt sized to fit entirely around a user's waist and a belt pad disposed along a portion of the belt to provide the padded section 212.
Body panel assembly 220 is adapted to form a child carrying area in cooperation with the wearer's torso. To this end, body panel assembly 220 comprises a body panel 222 (e.g., a front panel) that may be adapted to form a curved shape that supports the legs, hips, posterior and upper body of the child. Body panel 222 includes an end proximate to waistband 210 (referred to as the “bottom end” of body panel 222), opposed side edges 226 and a top end 227. The bottom end of body panel 222 is sewn or otherwise attached to the bottom portion of waistband 210, for example at or near the bottom edge of padded section 212. Moving away from waistband 210, the outer side edges 226 of body panel 222 are shaped such that the body panel width (indicated generally at 228) changes along at least a portion of the body panel 222. According to one embodiment, the outer side edges 226 curve or otherwise taper laterally inward from a width at the waistband 210 to a minimum body panel width and then curve or otherwise taper latterly outward again. According to one embodiment, the minimum body panel width occurs at a distance from the bottom end of body panel 222. The minimum body panel width, location of the minimum body panel width and the shape of side edges 226 can be selected to create desired carrier shapes in the multiple configurations.
In general, body panel 222, at least proximate to waistband 210, may be formed of an easily foldable textile construction. Body panel 222 may be formed from one or more panels joined together. For example, body panel 222 may include a center panel and side panels. Body panel 222 can be formed of a single material or multiple materials. For example, body panel 222 may be formed with an interior layer selected for comfort against a child's skin and an outer layer selected for breathability, fashion, stain resistance, etc. In some embodiments, body panel 222 and other portions of carrier 200 may incorporate engineered knitting to shape the carrier. For example, the center portion of the body panel may be shaped using engineered knitting. In some embodiments, the entire body panel 222 is shaped using seamless engineered knitting. In such an embodiment, body panel 222 can be constructed such that there are no seams or darts on the body of the carrier and all body shape is achieved through knitting.
According to one embodiment, each shoulder strap 260 is sewn or otherwise coupled to body panel assembly 220 at a respective first point, which may be referred to as an upper attachment point because it is an upper attachment point when the carrier is in use, and second point, which may be referred to as a lower attachment point or side attachment point. In the illustrated embodiment, each shoulder strap 260 extends from an upper corner or portion of body panel 222. The shoulder straps 260 are adapted to lift body panel assembly 220 and pull body panel assembly 220 toward the wearer to create the child carrying area. In the embodiment illustrated, each shoulder strap 260 has a portion that extends from an upper corner or portion of body panel 222 to a buckle member 264. The buckle member 264 connects to a respective buckle member 242, which is in turn attached to a webbing tab 240.
According to one embodiment, the shoulder straps 260 may have an expandable width. For example, shoulder straps 260 may include material that is folded over to form a slit 262 or other opening that can open/widen to allow the shoulder straps to widen.
Body panel assembly 220 comprises wings, flaps or other mechanism to direct tension or force from the lower shoulder strap attachment points away from the side edge 226, thus reducing the tension on outer edges 226 of body panel 222 during use and allowing greater freedom of movement for the child. In the illustrated embodiment, body panel assembly 220 comprises pair of shoulder strap attachment panels 230 that are sewn or otherwise attached to the interior of the body panel 222. Shoulder strap attachment panels 230 provide lower attachment points for the shoulder straps 260 and are adapted so that force or tension at the lower attachment points is transferred to body panel 222 away from side edges 226.
According to one embodiment, each shoulder strap attachment panel 230 is sewn or otherwise coupled to body panel 222 along an inner side edge 232 to body panel 222 at a position that is away from the outer side edges 226 of body panel 222. Even more particularly, according to one embodiment, the inner side edges 232 are coupled to the body panel 222 closer to the lateral centerline of the body panel than to the respective body panel side edge 226. While the shoulder strap attachment panels 230 of the illustrated embodiment are attached to body panel 222 away from the lateral centerline of body panel 222, the shoulder strap attachment panels 230 may be sewn or otherwise attached to body panel 222 at the lateral centerline in other embodiments.
Shoulder strap attachment panels 230 provide wings or flaps. More particularly, a portion of each shoulder strap attachment panel 230 is free to be pulled (e.g., swing) away from body panel 222. In the illustrated embodiment, the bottom edges, outer side edges 236 and top edges 238 of shoulder strap attachment panels 230 are free and thus shoulder strap attachment panels 230 may swing or otherwise be pulled away from away from body panel 222 (e.g., swing away from body panel 222).
According to one embodiment, all or a portion of each shoulder strap attachment panel 230 may have a width such that, when the carrier is spread open, the width of the carrier at the shoulder strap attachment panels 230 is greater than the width of the body panel 222 at the same distance from the bottom end of the body panel 222. In the illustrated embodiment, the top portions of the shoulder strap attachment panels 230 (the portions proximate to the respective top edges 238 and distal from waistband 210) have a sufficient length that they can extend past the closest body panel side edges 226. The outer edges 236 are cut so that shoulder strap attachment panels 230 are shaped to provide leg openings for a child's legs when shoulder strap attachment panels 230 are pulled away from body panel 222 by the shoulder straps.
Each shoulder strap attachment panel 230 includes an attachment point for a shoulder strap. In the illustrated embodiment, for example, each shoulder strap attachment panel 230 includes an attachment point at which a shoulder strap webbing attachment tab 240 is sewn or otherwise coupled to the exterior side of each shoulder strap attachment panel 230. Buckle members 242 are attached to the shoulder strap webbing attachment tabs 240 so that shoulder straps can be connected to strap webbing attachment tabs 240 using complementary buckle members 264. The shoulder strap attachment point on each shoulder strap attachment panel 230—that is, the point where the shoulder strap webbing attachment tab 240 is sewn or otherwise coupled to the shoulder strap attachment panel 230 in the illustrated embodiment—is located on a portion of the shoulder strap attachment panel 230 that can swing or otherwise move away from body panel 222. In some embodiments, the shoulder strap attachment point on each shoulder strap attachment panel 230 is latterly inboard of the respective side edge 226. Furthermore, the shoulder strap side attachment point on each shoulder strap attachment panel 230 is located so that it is farther away from the bottom edge of body panel 222 than the narrowest portion of body panel 222. In other embodiments, the attachment point may be located outboard of the respective side edge 226 and/or in another location relative to the narrowest part of the body panel 222.
It will be appreciated that shoulder strap attachment panels 230 are provided by way of example and other shapes of shoulder strap attachment panels may be used. Moreover, while shoulder strap attachment panels 230 are illustrated as separate panels, shoulder strap attachment panels 230 may be portions of a single panel that is sewn or otherwise attached to body panel 222 to form shoulder strap attachment panels. Further, shoulder strap attachment panels 230 may have a variety of form factors.
Moreover, the force or tension from a lower shoulder strap attachment point may be directed away from the side edges 226 of a body panel 222 by other mechanisms. For example, in another embodiment the second end of each shoulder strap (e.g., shoulder strap webbing attachment tabs 240 or other shoulder strap portion) may be sewn or otherwise attached directly to the interior of a body panel 222 away from the side edges 226. Thus, it will be appreciated that a variety of mechanisms may be used to reduce tension on the side edges of the body panel. Moreover, various mechanism to reduce tension on the side edges of a panel, such as shoulder strap attachment panels, can be used with a variety of carrier designs. By way of example, attachment panels of various forms or other mechanisms to reduce tension at the side edges of the body panel may be used with a variety of carrier designs, including carriers in which the body panel height and width is adjustable and designs in which the body panel height and width is not adjustable.
Similar to carrier 100, carrier 200 can provide enhanced freedom of movement by reducing tension on the laterally outer edges 226 of the panel 222 (e.g., as discussed in conjunction with
For example, in a configuration suitable for a larger child (e.g., a baby/toddler) body panel 222 is not folded behind waistband 210 but is lifted up to the exterior of the waistband 210. In this configuration, the base width of the carrier—the width of the seat proximate to waistband 210—is relatively wide. More particularly, in this configuration, the body panel 222 is exiting the waistband at the carrier's widest seat width as determined by the width of the bottom edge of body panel 222.
In another configuration, the body panel 222 is pulled up from the bottom of waistband 210 and behind waistband 210 between waistband 210 and the wearer's stomach. The lower portion of the body panel can be folded several times between the waistband 210 and the wearer's stomach, effectively shortening and narrowing the body panel 222. Body panel 222 is effectively shortened because the available height of body panel 222 to support a child is shorter than in the first configuration discussed above. The body panel is effectively narrower because the top edge of waistband 210 intersects the body panel 222 at an area that is narrower than the bottom edge of body panel 222—that is, the body panel 222 is exiting the waistband at a narrower area of body panel 222—creating a narrower base width and, hence, bucket seat than when the carrier is in the first configuration.
In the configuration with body panel 222 pulled up and folded behind waistband 210, the base edge of the seat proximate to the waistband is not fixed to the waistband. Consequently, the side edges of the carrier body panel 222 can be pushed together at the seat base to further narrow the base width of carrier.
As the child develops, the carrier can be reconfigured to accommodate the child.
In one embodiment, carrier 200 is adapted to support the child in a position with the child's femur approximately 90° to 120° (or other elevated position) from the coronal plane and to position the child's knees with an amount of spreading. The amount of spreading may depend on the developmental stage of the child and orientation with a newborn having less than 30°, then approximately 30°, then approximately 35°-40° and so on so, such that the final spread is approximately 40°-45°, though other amounts of spreading may be achieved including (e.g., for example approximately 55°). In one embodiment, the spreading may be at least 20° degrees from the median plane. The child's weight can be distributed across the child's bottom, thighs and back so that the sacrum does not bear too much weight and the child can rest with a more naturally curved “C” spine in a spread squat position that is believed to be better for pelvic development. It can be noted, however, that the child can be positioned in any comfortable position, preferably emphasizing a supportive posture rather than a posture where the child is primarily sitting on his or her sacrum.
Carrier 200 is adapted to provide a supportive bucket seat with a generally concave (e.g., “C” shape) inner profile. The minimum body panel width, position of the minimum body panel width and the shape of the side edges 226 can be selected such that body panel 222 can create multiple bucket seat configurations to ergonomically support a child through a range of ages/sizes and in multiple seating orientations. The side panels can be shaped so that the outer edge 226 is shorter than the inside/center edge of the side panel. In use, the outer side edges 226 can be higher than the center of the seat and spaced such that they pass under and around the child's thighs at a distance from the child's hips to lift the child's legs (e.g., above the knee). In some embodiments, additional support or padding may be placed proximate to edges 226 at the areas that will support a child's thighs.
According to one embodiment, carrier 200 is adapted so that the bucket seat formed in the narrower base width configuration can ergonomically support newborns and infants. Configured according to such a setting, the carrier may be adapted for placement of a child in a child carrying area of the child carrier with the infant's knees raised. In one embodiment, when adjusted to accommodate an infant, the carrier is adapted to support the infant in a position with the infant's femur at an angle of 90-120 degrees from the coronal plane. Additionally, the carrier can be adapted to support the infant in a position with the infant's knees at 45-60 degrees from the median plane. In particular embodiments, the carrier can be adapted to promote a spread-squat-position (also known as the “frog leg”, “frog”, “squat spread” or “M” position) in which the flexion at the hip joint is at least 90° and in some cases is 110° to 120° from the coronal plane with the knees spread as appropriate for the developmental stage. In one embodiment, the spreading may be at least 20° degrees from the median plane. The child's weight can be distributed across the child's bottom, thighs and back so that the sacrum does not bear too much weight and the child can rest with a more naturally curved “C” spine in a spread squat position that is believed to be better for pelvic development. It can be noted, however, that the child can be positioned in any comfortable position, preferably emphasizing a supportive posture rather than a posture where the child is primarily sitting on his or her sacrum.
In another configuration (e.g., a wider base configuration), the carrier can be adapted to support the larger child in a spread squat position with the child's femur approximately 90° to 120° (or other elevated position) from the coronal plane and to position the child's knees with an amount of spreading. The amount of spreading may depend on the developmental stage of the child and orientation of the child in the carrier. In one embodiment, the spreading may be at least 20° degrees from the median plane. The child's weight can be distributed across the child's bottom, thighs and back so that the sacrum does not bear too much weight. Further, the carrier can support the child's spine with a level of curvature appropriate of the child's developmental stage. It can be noted, however, that the child can be positioned in any comfortable position, preferably emphasizing a supportive posture rather than a posture where the child is primarily sitting on his or her sacrum.
Carrier 200 may be adjusted to provide ergonomic support for the child regardless of the size of the child through a supported range. In accordance with one embodiment, carrier 100 can be set for an infant with a narrower seat configuration. In this configuration, the bucket seat will be at its deepest with higher walls at the thigh support areas, lifting the child's thighs and knees to a greater angle and into a spread squat position appropriate for that size child. Similar to carrier 100 in
Similarly, carrier 200 can be set for a larger child with the seat at its widest setting. In this configuration, the bucket seat may be at its shallowest depth with lower walls at the thigh support areas, lifting the child's thighs and knees to a lesser angle and into a spread squat position appropriate for a larger sized child. Similar to carrier 100 as depicted in
Thus, the adjustable bucket seat is configurable in a plurality of configurations having different seat bucket depths and seat bucket widths. The different configurations can be adapted to support a child in a corresponding size range in a spread squat position. For example, in one embodiment, bucket seat can have a configuration adapted to ergonomically carry a child of 20-24 inches (generally corresponding to an infant of 0-3 months and over 7 pounds) in a spread squat position appropriate for the infant without requiring an infant insert. Furthermore, the carrier can have another configuration adapted to ergonomically carry a larger child in a spread squat position appropriate for that child's size. The configuration for carrying newborns/infants can correspond to the seat width being at the narrowest setting and the configuration for carrying larger children can correspond to the seat width being at a widest setting (shallowest bucket seat) (a toddler mode). It can be noted that the ranges provided above are provided by way of example and not limitation. Furthermore, the seat may have other configurations.
The user can thus adjust carrier 200 to support the child in an ergonomic spread squat position appropriate for the weight or size of the child with the child's pelvis, bottom and thighs all being supported. The child's weight can be supported so that the child is squatting in the seat rather than sitting with the child's weight primarily on the sacrum. The child can be supported with the knees higher than the bottom, in some cases higher than 90 degrees. The carrier can be adjusted to form a sling or pouch that is wider than the child's hips.
It can be noted that panel 222 is provided by way of example and panel 222 can have a variety of form factors. Moreover, a carrier with height and/or width adjustment according to the teachings of the present disclosure may have a variety of shoulder strap configurations. In one embodiment, for example, the lower/side attachment shoulder strap attachment points may occur on body panel 222 at or proximate to the side edges 226. Such an embodiment, while possibly exhibiting increased tension at the side edges, would still provide the advantage of easy height/width adjustment to ergonomically support a child through a range of ages/sizes.
Moreover, in some embodiments carrier 200 includes a retaining strap on the front of the waistband so that the bottom portion of body panel 122 can be folded between the waistband and retaining strap rather than between the waistband and the wearer. Other retaining mechanisms, such as snaps, retaining loops may also be used to maintain body panel 122 in a folded configuration.
In the illustrated embodiment, carrier 300 includes a horizontal retaining strap 350 formed of webbing or the like attached to the midsection of waistband 310. Between the attached ends, retaining strap 350 is not attached to the waistband and thus comprises an open length 352. According to one embodiment, the open length 352 is approximately as long as the width of body panel 322 where body panel 322 is attached to waistband 310. In other embodiments, open length 352 is longer or shorter than the bottom width of body panel 322.
Body panel 322 can be folded up between the front of waistband 310 and panel retaining strap 350. With body panel 322 folded up, the base width of the resulting bucket seat is the width of body panel 322 where body panel 322 exits from between waistband 310 and panel retaining strap. For example, in the configuration of
Thus, the bottom portion of body panel 322 can be folded up between retaining strap 350 and waistband 310 to selectively narrow the base width of the bucket seat and shorten the effective height of the carrier. The material, length, attachment points, and tension in retaining strap 350 are selected such that, when carrier 300 is worn, there is sufficient tension in retaining strap 350 to retain body panel 322 under expected loads.
In the embodiment illustrated, the bottom portion of body panel 322 folds such that body panel 322 run up between the waistband and retaining strap without additional folds between the waistband 310 and retaining strap 350, in other embodiments, the carrier is constructed such that the bottom portion of a body panel can be folded multiple times (e.g., between a retaining strap and waistband or using another retaining mechanism).
Similar to as discussed above with respect to carriers 100, 200, body panel 322 can also be lifted up to the front of the waistband 310 and retaining strap 350 to achieve another configuration—that is, a configuration in which body panel 322 is not fed or folded between retaining strap 350 and waistband 310. In such a configuration, the effective height of the body panel (the height of the body panel used to support the child) is longer and the seat base is wider. The second configuration can be adapted to ergonomically support a larger child.
