This invention relates to child carriers, also called “baby carriers”, “infant carriers” and “toddler carriers” that can be worn by an adult with the child being positioned to face toward the wearer or away from the wearer. More particularly, the invention relates to a child carrier including the improvement of an adjustable seat platform, the seat platform being adjustably configurable to ergonomically and safely support the body of the child being carried.
Conventional child carriers, while they are functional, they are not optimally designed for the safety, comfort and health of the child, nor for the ease-of-use and comfort of the caregiver. Furthermore, many carriers are optimally suited for carrying a child in single orientation, either on the front of and with the child facing the caregiver or on the front of and with the child facing away from the caregiver.
One of the difficulties of currently available child carriers is that they are unsafe and difficult to put on and to secure the child. Some carriers require that a wearer let go of the child to attach or tighten buckles that require both hands, which can result in harm to the child.
Examples of conventional child carriers include those described in Frost (U.S. Pat. No. 7,322,498), Gunter et al. (U.S. Pat. No. 8,636,181) and Telford et al. (US 2014/0263491); the contents of each of which are hereby incorporated by reference.
Furthermore, the medical community has identified certain problems with the resulting position of the child being carried by many child carriers, including those carriers as disclosed in Frost, Gunter et al. and Telford et al., above. This position consists of the child dangling from, or being mainly supported by, their crotch. It is said that this type of support can lead to hip problems in the infant being carried, such as developmental dysplasia of the hip, as well as general discomfort. The body or pouch of many carriers attaches directly to the top of the hip belt, resulting in a narrow wedge of space where the child sits, thus squeezing the child's pelvis and causing his or her legs to hang down toward the ground. Additional information regarding child-carrier induced hip dysplasia, and other related problems, can be reviewed at: http://hipdysplasia.org/developmental-dysplasia-of-the-hip/prevention/baby-carriers-seats-and-other-equipment/.
The instant invention seeks to provide an improved child carrier aimed at solving these and other problems in the art.
A child carrier is disclosed, the child carrier includes: a hip belt, a pouch assembly attached to the hip belt along an upper seam thereof, a body harness attached to the pouch assembly for strapping the child carrier about an adult wearer, with the child carrier further characterized by an adjustable seat platform assembly coupled to the hip belt; the adjustable seat platform assembly including a seat platform attached to the hip belt along the upper seam, and an adjustable seat strap configured to erect the seat platform in accordance with a desired application or use of the child carrier.
In the following description, for purposes of explanation and not limitation, details and descriptions are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these details and descriptions. The following details and descriptions are intended to illustrate various embodiments of the invention; however, these details and descriptions are not intended to limit the scope of the invention as set forth in the claims.
Now, in a general embodiment, the invention includes a child carrier with a padded hip belt (or “belt assembly”) that can be adjusted to fit the caregiver while providing an optimal seat for the child's comfort and well-being, specifically as it relates to the child's hips, bottom and upper legs.
Additionally, in some embodiments, the carrier can include six points of adjustment, including: a first shoulder strap buckle, a second shoulder strap buckle, a first side buckle, a second side buckle, a belt buckle assembly, and the seat buckle, which affords the ability to optimally configure the carrier for the child's comfort and for the desired orientation or position of the child in either inward-facing or outward-facing positions for a variety of different sized caregivers. These adjustment points enable the wearer to easily secure the child in the carrying position without taking a hand off of the child. To achieve this, the top two straps are loosened, allowing the carrier to fall away from the front of the caregiver the child is brought into the desired position, then the straps are tightened with one hand, while the other hand remains on the child.
Additionally, the upper straps may be adjusted to position the carrier on the caregiver for proper fit and general comfort of the child and caregiver (or “wearer”).
The belt assembly contains a seat platform that is radially attached along one side to the front, top, inner portion of the hip belt (the “upper seam”) on one side and is attached to a strap (or “belt assembly adjustment strap”), which is attached at two points on the inner circumference of the circular belt assembly, the belt assembly adjustment strap can be tightened, causing a portion of the belt to extend away from the caregiver to form a bowed front portion and a seat for the child. The resulting configuration provides a support or platform for the child's bottom and thighs, which is especially important in the face-out position (i.e. with the child facing away from the wearer). This seat platform is adjustable to afford more support for the outward-facing child orientation, and less support for the inward-facing orientation.
In one embodiment, the seat platform can be manufactured to include two layers of polyester fabric that are attached to the upper seam of the belt assembly using strong thread. For purposes of defining the configuration of the seat platform, it is said that a first side of the seat platform is attached to the belt assembly along the upper seam. A channel or “loop” is formed between the two layers; the loop extends along the length of the seat platform along a second side that is opposite the first side. A strip of webbing (or “adjustment strap”) runs though this channel or “loop”. The adjustment strap is adjustable, and when tightened, results in the desired seat configuration by forming a bowed or bent front portion of the belt assembly. It should be noted that there should be enough rigidity in the belt assembly such that when the belt assembly adjustment strap is tightened, the amount of material beyond the adjustment strap sticks out to form a bowed or bent front portion of the belt assembly thereby providing the desired seat, while the wearer can still tighten the hip belt to secure the carrier and transfer load to the hips.
Now turning to the drawings, wherein an illustrated embodiment is described,
A prototype has been produced and tested. In a prototype embodiment developed by the named inventors, the prototype embodiment is similar to the illustrated embodiment herein, the construction of the belt assembly included a polyester fabric exterior that is approximately 0.25 mm thick; then on the inside is disposed a strip of Ethylene-vinyl acetate (EVA) foam with a density of approximately 30 g/cc and thickness of 10 mm was used; then a 10 mm layer of standard density polyurethane foam was used on the inside of the hip belt, between the EVA foam and the polyester outer layer for comfort.
The shoulder strap included a semi-structural padded shoulder harness, which generally fits in one location on the back of the wearer. There are 4 straps, one extending from each of the attachment points that allow for attachment to the front body of the child carrier. These straps can be adjusted to position the child ideally on the front of the caregiver. All adjustments are made from the front of the carrier; the wearer does not need to ever reach behind their head, neck, or back.
The straps also offer a means to allow the transition of the child into the carrier. The wearer starts by completely attaching the carrier onto their body and adjusting it how they like. Then the wearer will loosen the upper straps that attach the body of the carrier to the shoulder straps, allowing the carrier body to fall away from the body of the wearer. The wearer then brings the child to their chest, into the carry position, and then cinches up the top straps to secure the child, which can be completed with one hand.
The platform seat provides a means of providing comfort and support by extending the belt assembly outward from the wearer in a manner to create a support ledge or seat for the child. This is accomplished by attaching a belt assembly adjustment strap and integrated fabric seat platform that when tightened produces a ledge that supports the child's bottom, thighs, and back. The body portion or “pouch assembly” of a conventional child carrier attaches directly to the hip belt at the wearer's body. The resulting space for the child doesn't allow much room for the child's bottom and results in squeezing the child's bottom, legs, and crotch into a “V” shaped space. In contrast, the child carrier disclosed herein provides an ergonomic seat platform for providing comfort and improved safety to a child carried by the child carrier.
The four-point adjustable harness shown herein enables the wearer to adjust the carrier to optimally fit the wearer and the child. The four points of attachment to the shoulder harness enable the wearer to carry the child high on their body by tightening the upper straps or wear the child the low by loosening the upper straps. This height and fit adjustment can also be used optimally position the child for breast-feeding while in the carrier. The lower two attachment points (side buckles) control how close the child is to the wearer. This adjustment should be modified to provide the most comfort to the child and will be different for inward-facing and outward-facing child configurations. Each of the adjustment points of the prototype embodiment utilize nylon webbing and ladder buckles, but other load bearing materials and adjustable connectors could be also used to produce a similar result.
In the prototype embodiment that was produced, the length of the adjustment strap is approximately 36 cm in its extended position and is tightened up to about 20 cm to produce the bottom seat configuration, but is adjustable to any length between about 15 cm and 36 cm. This results in a seat that is about 10 cm by about 20 cm.
The belt assembly is an important element of the seat in that its structure is key to the shape and integrity of the child seat. The preferred embodiment relies on a hip belt height of approximately 9 cm to provide the desired degree of stiffness. If a shorter hip belt design is desired, the stiffness of the belt would need to increase to accommodate the decrease in dimensional stiffness.
The material used in the belt assembly adjustment strap, which makes the seat, included a 1″ wide nylon webbing, although any number of load bearing materials such as a cylindrical cord or wire, rope fabric strip, or thicker or thinner webbing could be used. While the prototype embodiment utilized a ladder buckle, other types of materials would require the appropriate buckle type for type of material used.
The seat configuration extends out away from the wearer about 10 cm. This distance can be increased by increasing the length of the adjustment strap. The effective seat could extend outward to provide a larger seat, which would be desirable for a larger child.
In the prototype embodiment, the shoulder strap design included a cross design. Other design configurations that would produce a similar result would include configurations with curved strap elements. While the shoulder strap design included polyester fabric with a foam interior, a single layer breathable fabric could also be used to provide comfort and breathability.
Advantages of the instant child carrier include, without limitation, a child carrier that: (a) provides support to the child's bottom and thighs, positioning the child's legs in an ergonomically correct position which is referred as the “frog leg” or “squat spread” position; (b) enables the wearer of the carrier to first put on the carrier and then secure the child in the carrier without letting go of the child; and (c) affords the adjustability to position the carrier to optimally suite the needs of the wearer by adjusting each of the shoulder harness attach points.
Alternative Embodiment
Now turning to
The child carrier may optionally comprise a hood 510 coupled to the pouch assembly and configured to extend upwardly therefrom to cover the head of a child inside the child carrier. The hood may comprise one or more hood straps 511 extending from the hood and configured to couple with a portion of the body panel. For example, and not limitation, the hood straps 511 may attach to one of the body panel or the shoulder straps of the body harness via securing elements 512.
In one embodiment, the belt assembly 540 includes: a hip pad 544, and a waist belt 542 coupled to the hip pad collectively defining a circumference of the belt assembly. Additionally, the hip pad may further comprise a parabolic seam 543 extending about a portion of the hip pad, the parabolic seam forming the front portion and seat platform as shown in
The body harness may further comprise: a quick-release buckle 522a and receiver 522b configured to removably attach each of two shoulder straps of the body harness. The quick-release buckle may comprise a slotted engagement feature, a magnet, or a combination thereof. The harness is shown with a buckle having a protruding engagement feature, and a receiver with a slotted void, wherein the protruding engagement feature fits within the void. In addition, a magnetic feature, such as a magnet and metal plate, is embedded within the quick-release buckle. A neodymium magnet is preferably implemented due to its magnetic strength. The quick-release buckle can be implemented with buckle-straps 521 as shown. In addition, the shoulder straps may comprise conventional adjustment members 523 and 524.
In some preferred embodiments, the pouch assembly comprises a mesh fabric for breathability. The mesh fabric is generally sewn in as a panel extending about a majority of the body panel. This feature allows for a cooler environment for a child within the carrier. The child carrier may be used with or without a conventional child insert as known by one with skill in the art.
