Description

FIELD THE INVENTION

Various embodiments of the technology disclosed in the present application relate to child carriers, backpacks, and bags. Child carriers may be used to carry a child and items on a person's back. Some embodiments disclosed herein relate to collapsible or alterable frames for such times.

BACKGROUND OF THE INVENTION

Child carriers, backpacks, luggage, and bags have been designed and used. Backpacks have been used to carry items on a person's back. Child carriers have been used to carry children and items on a person's back, and sometimes on a person's chest. In the past, some backpacks and child carriers have had fabric bodies with frames to provide structural support and strength. Such frames have been made from aluminum or other metal tubing to provide stiffness, strength, and light weight. In other instances, the frames may have members formed from plastics or composites.

Frames have been at least partially collapsible and have used hinges or pins to provide attachment and allow relative movement of different frame members. In child carriers, frames have allowed the apparatus to stand up on a surface. The frames, however, were susceptible to damage at the hinge or pin with excessive force. An example of an excessive force is a downward force on the top of the apparatus when the apparatus is standing up that causes damage. Another example of an excessive force is the force associated with setting the device down too hard when uncollapsed. In the prior art, such an excessive force would typically break or buckle the frame, potentially rendering the apparatus unsafe or unusable.

Room for improvement exists over the prior art. Needs or potential areas for benefit exist for apparatuses that include frames that are alterable or collapsible, that do not break or do not buckle when an excessive force is applied (e.g., at least for certain categories of excessive force), or a combination thereof. Further, needs or potential areas for benefit exist for apparatuses that are light weight, strong, damage resistant, or a combination thereof. Needs or potential areas for benefit exist in these areas individually as well as in various combinations of these areas. Moreover, room for improvement exists over the prior art in the design of alterable frames generally as well as in specific applications. Potential for benefit or improvement exists in these and other areas that may be apparent to a person of skill in the art having studied this document.

SUMMARY OF PARTICULAR EMBODIMENTS OF THE INVENTION

Various embodiments are or include child carriers, backpacks, bags, luggage, and methods of making such products. Further, various backpacks, for instance, can be used to carry items on a person's back, for example, while hiking, backpacking, mountaineering, canyoneering, mountain biking, rock climbing, skiing, traveling, or going to and from school (or between classes), as examples. Still further, child carriers can be used (e.g., by an adult) to carry a child, for example, while hiking, backpacking, or traveling, as examples. Various embodiments at least partially address one or more of the needs or potential areas for benefit or improvement that are described herein. Further, some embodiments provide, for example, as a benefit, a reduction in weight, an improvement in strength or damage resistance, or a combination thereof, for example. Improvements may exist in these areas individually as well as in various combinations of these areas, as further examples. Other areas for benefit or improvement may be apparent to a person of skill in the art having studied this document. Various embodiments of the invention are specifically described herein, and other embodiments may be apparent to a person of skill in this area of technology.

DESCRIPTION

This patent application describes, among other things, examples of certain embodiments, and certain aspects of a frame that is configured for at least a collapsed position and an un-collapsed position. The frame may be referred to as a collapsible frame or an alterable frame, which terms are generally interchangeable herein. Other embodiments may differ from the particular examples described in detail herein. Various embodiments are or concern child carriers, backpacks, bags, and luggage, and apparatuses, for example, with alterable frames. Still further, various embodiments concern methods of making child carriers, backpacks, bags, luggage, and (e.g., alterable) frames, for example.

Various embodiments of the technology described herein are described with respect to a child carrier. The technology, however, is not limited to frames for child carriers, but could be incorporated into other devices, such as, backpacks, bags, and luggage. The frames may resist buckling or breaking, for example, when an excessive force is applied. Frame members may move, for example, relative to each other, for instance, until engagement members engage. This may occur when expanding a frame. In a number of embodiments, a fabric body may allow for movement of frame members, limit such movement, support & strengthen the frame members, or a combination thereof. Frame members may be located within sleeves within the fabric body. Further, frame members may be formed from metals or composites. In certain embodiments, the frame members may be solid steel or stainless steel, as examples. In other embodiments, the frame members may be aluminum or hollow aluminum. In other embodiments, the frame members may be carbon based, fiberglass, or the like. Frame members may be curved, for example, to control direction of deformation, optimize support from the fabric body, or both. Still further, various bends in the frame members may form the engagement features, may join sections of the frame members, or both. Some embodiments include three frame members including a U-shaped frame member, such as frame member 12 in FIG. 2, and an inverted U-shaped frame member, such as frame member 10 in FIG. 2 that cross at the engagement members 30 in FIG. 2, for example, when the frame is uncollapsed. In a child carrier 1 as shown in FIG. 1, the collapsible frame members may be arranged or configured as shown in FIGS. 2 and 3. The two frame members 10 and 12 may form a three-dimensional structure 14 (FIG. 1) in which the child is suspended. In a number of embodiments, a third (e.g., rectangular) frame member 16 may provide vertical structure, for example, at the user's back. As shown in FIG. 1, the frame members 10, 12, and 16 may be internal to a fabric child carrier 1. In some instances, the fabric of the child carrier 1 may include channels to receive the tubular members of the frame members 10, 12, and 16. The child carrier may include buckles or the like secure the frame open in some embodiments. Even further still, in particular embodiments, a cover may zip over the harness for shipping. Weight and cost may be saved in comparison with alternative designs. The frame members 10, 12, and 16 are described herein with respect to a child carrier 1, but could be implemented in a backpack, luggage item, or the like. As shown in FIGS. 2 and 3, the frame members 10 and 12 are generally U-shaped (typically with one inverted with respect to the other) with longitudinally extending arms 18 and a transverse base 20 connecting one end 21 the arms 18. The terminal ends 23 of the arms 18 may terminate in a crimped member. The frame member 16 is generally vertical, relative to the angled frames 10 and 12. The frame member 16 has a pair of longitudinally extending arms 22 and a pair of transverse bases 24 and 26 connecting each end of the longitudinally extending arms 22.

Various embodiments are or include an apparatus, for example, for carrying items. In a number of embodiments, for instance, the apparatus includes a frame, for example, a collapsible frame. For example, in particular embodiments, the frame includes a first frame member, such as frame member 10 and a second frame member, such as frame member 12. Further, in some embodiments, the first frame member has a first engagement member 30 as shown in FIGS. 11 and 12. Also , the second frame member may have a second engagement member 30. The engagement member 30 optionally includes an engagement lock member 32 as shown in FIGS. 11 and 12. The frames 10 and 12 interconnecting at the first and second engagement members 30 (or just the first or just the second engagement member 30) provides point where a user may potentially pinch a finger. Thus, in certain embodiments, a pinch guard 32 may be used, which may be plastic, fabric, or metal, in place of or in combination with the engagement lock member 32. As shown in FIGS. 11 and 12, the engagement member 30 includes an elbow in the longitudinal arms 18 of the frame members 10 and 12. The arms 18 slide long each other until the elbows of the engagement members 30 meet, which forms a snap lock. The engagement lock member 32 is shown as a circular member that friction fits over the engagement members 30 to inhibit inadvertently releasing the engagement members 30. Still further, in particular embodiments, when the collapsible frame is expanded (e.g., by the user, for instance, from a collapsed configuration to an uncollapsed configuration), the first frame member moves relative to the second frame member as shown in FIGS. 8. The frame members 10 and 12 move towards the frame member 16 in the directions shown by arrows A and B to collapse and would move in the opposite direction to uncollapse. Note, the terms uncollapsed and expanded may be used interchangibly herein. Even further, in some such embodiments, the first frame member moves relative to the second frame member until the first engagement feature engages the second engagement feature. As shown in FIG. 7, the frame members 10 and 12 are collapsed to frame member 16. The frame members 10 and 12 move relative to each other and frame member 16 such that the longitudinal arms 18 slide along one another until they engage at the engagement members 30, as shown in FIGS. 11 and 12. The frame members 10 and 12 may be biased such that when the engagement members 30 intersect, the frame members 10 and 12 form a snap lock. Once the engagement members 30 engage, forming a snap lock fitting, the engagement lock member 32 is moved, such as by rotation or sliding along the frame members, into place to hold the frame members in an uncollapsed configuration as shown in FIG. 10. In some embodiments, the engagement lock member 32 may be optional. Also, if a single engagement member 30 is used, the snap lock forms when the frame member, such as frame member 10′s engagement member 30 slide to engage an arm 18 of frame member 12.

In a number of embodiments, the first engagement member 30 is formed by making at least one bend or elbow in the first frame member 10, the first engagement member 30 includes at least one bend in the first frame member, or both. Further, in some embodiments, the first engagement member is formed by making multiple bends or elbows in the first frame member, the first engagement member is formed by making bends in substantially opposite directions in the first frame member 10, the first engagement member is formed by making substantially adjacent (or adjacent) bends in the first frame member, or a combination thereof. Still further, in a number of embodiments, the second engagement member 30 is formed by making at least one bend or elbow in the second frame member 12, the second engagement member 30 includes at least one bend in the second frame member 12, or both. Even further, in various embodiments, the second engagement member is formed by making multiple bends or elbows in the second frame member, the second engagement member is formed by making bends in substantially opposite directions in the second frame, the second engagement member 30 is formed by making substantially adjacent (or adjacent) bends in the second frame member, or a combination thereof. Even further still, in particular embodiments, the second engagement member 30 is formed by making three bends in the second frame member. Having multiple engagement members 30 in the frame members 10 and 12 may allow for different settings on the child carrier such that the opening, in which the child is fitted, may be alterable in size in the uncollapsed configuration.

Further, in some embodiments, an apparatus for carrying items, such as the child carrier 1, includes a collapsible frame that includes a first frame member 10 and a second frame member 12 and when the collapsible frame is expanded (e.g., from a collapsed configuration to an uncollapsed configuration), the second frame member 12 slides against the first frame member 10, or at least the longitudinal arms 18 slide relative to each other. Still further, in some such embodiments, the first frame member 10 has a first engagement member 30 and when the collapsible frame is expanded (e.g., from the collapsed configuration to the uncollapsed configuration), the second frame member 12 moves relative to the first frame member 10, for instance, until the first engagement member 30 engages the second frame member 12. In this instance, which is shown in FIG. 6, only the first frame member 10 has an engagement member 30. Further still, in some such embodiments, the second frame member 12 has a second engagement member 30 and when the collapsible frame is expanded (e.g., from the collapsed configuration to the uncollapsed configuration), the second frame member 12 moves relative to the first frame member 10, until the first engagement member 30 engages the second engagement member 30.

More broadly, in various embodiments, an apparatus includes an alterable frame assembly, such as alterable frame assembly 2 shown in FIG. 2. In some such embodiments, for example, the (e.g., alterable) frame includes a first frame member 10 (e.g., having a first engagement member 30) and a second frame member 12 (e.g., having a second engagement member 30, which is optional). In some such embodiments, for instance, when the frame is altered from a first configuration to a second configuration, the first frame member 10 moves relative to the second frame member 12. For example, in particular embodiments shown in the FIGs, when the frame assembly 2 is altered from a first configuration 4 shown in FIG. 1 (expanded or uncollapsed) to a second configuration 3 shown in FIG. 4 (collapsed), the first frame member 10 moves relative to the second frame member 12 until the first engagement member 30 engages the second engagement member 30 or until the first engagement member 30 engages the longitudinal arm 18 of the second frame member 12. Further, in some embodiments of an apparatus that includes the frame assembly 2, where the frame assembly 2 includes a first frame member 10 and a second frame member 12, when the frame is altered from a first configuration 4 to a second configuration 3, the second frame member 12 slides against the first frame member 10. In some (e.g., such) embodiments, the first frame member 10 has a first engagement member 30 and when the frame is altered from the first configuration 4 to the second configuration 3, the second frame member 12 moves relative to the first frame member 10 until the first engagement member 30 engages the second frame member 12. Still further, in particular embodiments, the second frame member 12 has a second engagement member 30 and when the frame assembly 2 is altered from the first configuration 4 to the second configuration 3, the second frame member 12 moves relative to the first frame member 10 until the first engagement member 30 engages the second engagement feature.

In various embodiments, the apparatus 1 includes a first fastener 100 (e.g., a buckle) and when the frame is in the first configuration 4 or in the second configuration 3, as examples, the first fastener can be fastened to hold the (e.g., alterable) frame assembly 2 (e.g., in the first or second configurations 4, 3). Further, certain embodiments (e.g., of an apparatus for carrying items) include a fabric body 102, a first fastener 100 (e.g., connected to the fabric body), and a (e.g., collapsible) frame assembly 2 (e.g., within the fabric body). Still further, in some embodiments, the (e.g., collapsible) frame assembly 2 includes a first frame member 10 and a second frame member 12. Even further, in some embodiments, when the (e.g., collapsible) frame is in the first configuration 4 (e.g., to an uncollapsed configuration), the first fastener 100 can be fastened to hold the (e.g., collapsible) frame assembly 2 (e.g., in the first configuration 4). Some such embodiments include two or more fasteners 100, for example, on opposite sides.

In some embodiments (e.g., having the first frame member 10 and the second frame member 12), the apparatus 1 (e.g., further) includes a third frame member 16, for example, having a first end comprising a transverse 24 and a second end comprising a transverse base 26 (e.g., opposite the first end). Further, in some embodiments, for example, when the frame assembly 2 is expanded from the second configuration 3 to the first configuration 4, or when the frame assembly 2 is altered (e.g., from the first configuration 4 to the second configuration 3), the first frame member 10 rotates (or pivots) relative to the third frame member 16. In other words, the longitudinal arms 18 of the first frame member 10 rotate about an axis parallel to the transverse base 26. Similarly, when the frame assembly 2 is expanded from the second configuration 3 to the first configuration 4, the second frame member 12 rotates (or pivots) relative to the third frame member 16. In other words, the longitudinal arms 18 of the second frame member 12 rotate about an axis parallel to the transverse base 24.

Some embodiments (e.g., of an apparatus for carrying items), include a (e.g., collapsible) frame assembly 2 that includes a first frame member 10 and a third frame member 16. The third frame member has a first end comprising the transverse base 24 and a second end comprising the transverse base 26 (e.g., the second end being opposite the first end). Moreover, in a number of embodiments, for example, when the collapsible frame is expanded from the second configuration 3 to the first configuration 4, the first frame member 10 rotates around the third frame member 16 as explained above. In some such embodiments, the apparatus 1 or the (e.g., collapsible) frame assembly 2 further includes the second frame member 12 (e.g., described herein). The second frame member 12, similarly, rotates relative to the third frame member 16 as explained above.

Even further still, in some embodiments, an apparatus 1 includes an alterable frame assembly 2 that includes a first frame member 10 and a third frame member 16 (e.g., having transverse bases 24 and 26 connected by longitudinal arms 22), and when the frame assembly 1 is altered (e.g., from a first configuration 4 to a second configuration 3), the first frame member 10 rotates about an axis generally parallel to one of the transverse bases 24 and 26 of the third frame member 16. If a second frame member 12 is included, the second frame member 12 would rotate about an axis generally parallel to the other of the transverse bases 24 and 26 in a movement similar to those described above.

In a number of embodiments of the apparatus 1 that includes the third frame member 16, the first frame member is connected to the third frame member with fabric, such as the fabric body 102 of the apparatus 1 shown in FIGS. 1 and FIGS. 13-21. In various embodiments, the fabric allows the first frame member 10 to rotate relative to the third frame member 16 as described above. In some embodiments, the fabric body 102 limits rotation (and/or movement) of the first frame member 10 to a first angle, as measured by the acute angle formed between the longitudinal arms 18 of the first frame member 10 and the third frame member 16. Even further, in various embodiments, the first angle is less than 45 degrees, the first angle is less than 30 degrees, or the first angle is less than 20 degrees, as examples. Further still, in some embodiments, the first angle is more than 10 degrees or the first angle is more than 15 degrees, as examples. In some embodiments, the second frame member 16 is connected to the third frame member also within fabric body 102 and the fabric allows the second frame member to rotate as described above. The fabric body 102 limits rotation of the second frame member 12 similar to the first frame member 10 and may form a second angle between the longitudinal arms 18 of the second frame member 12 and the third frame member 16, with angles similar to the first angle above.

In various embodiments, the apparatus 1 has a top and a bottom. Further, in a number of embodiments, the first end comprising transverse member 26 of the third frame member 16 is at the top of the apparatus 1, and the second end comprising transverse member 24 of the third frame member 16 is at the bottom of the apparatus, which of course could be reversed. Still further, in some embodiments, the transverse member 24 may include one or more feet 5, such as a first foot 5 and a second foot 5, see FIG. 2. In some embodiments, the second frame 2 may have one or more feet 5 on the transverse base 20 as shown in FIG. 3 The one or more feet 5 may facilitate the stability of the apparatus 1 (e.g., in the uncollapsed configuration) when the apparatus 1 is placed on a surface on the first foot, the second foot, the third foot, and the fourth foot. FIG. 1 shows an example.

Certain embodiments are or include an apparatus for an adult to use to carry a child (e.g., a child carrier). In other embodiments, the apparatus 1 may be a backpack, a luggage, or dufflebag, or the like. In various embodiments, the apparatus includes a frame, for example, that includes multiple frame members. Further, in a number of embodiments, the frame is collapsible. Still further, in some embodiments, the apparatus does not include a pin joining any of the multiple frame members, the apparatus does not include a hinge joining any of the multiple frame members, or both (i.e., no hinge and no pin). In other words, frame assembly 2 includes frame member 10, frame member 12, and frame member 16, but the frame members are not specifically interconnected. Rather, the fabric body 102 is shaped to hold the frame members 10, 12, and 16 in position relatively to each other in the various configurations and movement between the same. Even further, in particular embodiments, the apparatus includes fabric joining the multiple frame members, the fabric allows the frame to collapse, or both. The fabric body 102 of the apparatus may include inner and outer panels that define a space therebetween. The frame members, such as frame members 10, 12, and 16 reside in the space defined by the various inner and outer panels. The movement of the frame members 10, 12, and 16 relative to each other as described herein is facilitate by the frame member moving within the space between the inner and outer panels, such as, along a seam or the like. Further still, in various embodiments, the apparatus includes a frame that includes multiple frame members, the frame is collapsible, the apparatus includes fabric joining the multiple frame members, and the fabric allows the frame to collapse. In certain embodiments, the fabric allows the frame to collapse when the first fastener, second fastener, or both (e.g., described herein) are unfastened (e.g., unbuckled).

As mentioned, in various embodiments, the apparatus 1 (e.g., for an adult to use to carry a child) includes a frame assembly 2 that includes a first frame member 10, a second frame member 12, and a third frame member 16 (e.g., having a first end and a second end). The third frame member 16 provides vertical structure and the first frame member 10 and the second frame member 12 form a cradle or three-dimensional structure, for example, within which the child is suspended, or a combination thereof. Further, in some embodiments, the apparatus 1 further includes (e.g., within the 3-dimensional structure) a seat for the child (FIG. 16), a harness for the child (FIG. 14), or both (FIG. 17). Still further, in a number of embodiments, the third frame member 16 provides vertical structure for the apparatus 1, for the adult, or both. Even further, in some embodiments, the apparatus includes textile (e.g., fabric) sleeves, as are generally known in the art, but not specifically shown, for example, configured to allow the first frame member and the second frame member to collapse. In some embodiments, the fabric body 102 may have an inner and outer fabric layer that define a sleeve (or space) therebetween in which the frame members move. Even further still, in some embodiments, the textile (e.g., fabric) sleeves are configured to allow the first frame member 10 and the second frame member 12 to lock together at engagement members 30, for example, when the frame assembly 1 or the first frame member 10 and the second frame member 12 are opened (e.g., when expanded or uncollapsed). Further still, in various embodiments, the apparatus further includes (e.g., two) side release fasteners 100, such as buckles 100 shown in FIGS. 22-27, for example, that secure the first frame member and the second frame member (e.g., when the apparatus is opened). While fastener 100 is described as a buckle, having an associated male and female part, the fastener 100 may comprise other devices such as snaps (also having a male and female part), hook & loop piles, releasable adhesives, slide locks, or the like.

In some embodiments, the apparatus 1 (e.g., for carrying items) includes a frame assembly 2 that includes the first frame member 10, the second frame member 12, and the third frame member 16 (e.g., having transverse bases 24 and 26), and the first frame member 10 crosses the second frame member 12 at the engagement member 30, which may be a single engagement member 30 in the first frame member 10 or a pair of engagement members 30 with one in the first frame member 10 and another in the second frame member 12. To facilitate the locking arrangement, the frame members 10 and 12 may be biased such that longitudinal arms 18 move towards each other. In various such embodiments, for example, the transverse base 26 is opposite the transverse base 24, the first frame member 10 extends from the transverse base 24 of the third frame member 16, the second frame member 12 extends from the transverse base 26 of the third frame member 16. Moreover, in various embodiments that include the first frame member 10, the first frame member 10 includes a first section of the first frame member, a second section of the first frame member, and a third section of the first frame member. Furthermore, in some embodiments, the first section of the first frame member is separated from the second section of the first frame member by a first bend or elbow in the first frame member, which corresponds to the engagement member 30, the second section of the first frame member is separated from the third section of the first frame member by a second bend or elbow in the first frame member, which corresponds to the engagement member 30, or both. Even further, in various embodiments, the first bend in the first frame member is a substantially right angle, the second bend in the first frame member is a substantially right angle, or both. As used herein, unless indicated otherwise, “substantially” means within plus or minus ten percent. So “a substantially right angle” is an angle between 81 and 99 degrees. Further, where the word “substantially” is used herein, other embodiments are contemplated where the indicated value is within 1, 2, 3, 4, 5, 6, 8, 12, 15, 20, 25, 30, 40, or 50 percent, as other examples.

In particular embodiments, the first section of the first frame member 10 is substantially parallel to the third section of the first frame member 10. As used herein, “substantially parallel” means parallel to within ten percent of the length of the section over at least 90 percent of the length of the section, except that less than half of the length of the section may be substantially opposite hand. Further, in some embodiments, the first section of the first frame member is substantially opposite hand to the third section of the first frame member. As used herein, “substantially opposite hand” means opposite hand to within ten degrees of angle and to within ten percent of an overall length of the section. Still further, in certain embodiments, the first section of the first frame member has a first radius of curvature of the first frame member in a substantially common direction extending over at least 25 percent of a length of the first section of the first frame member. As used herein, a “substantially common direction” means, when referring to a radius of curvature, that a portion of the section having the radius of curvature is all within a common plane to within ten percent of an arc length of the portion of the section having the radius of curvature. In other embodiments, the first radius of curvature of the first frame member in the substantially common direction extends over at least 20, 30, 35, 40, 50, 60, or 75 percent of the length of the first section of the first frame member, as other examples. Even further, in some embodiments, the first radius of curvature of the first frame member is concave toward (e.g., the second end of) the third frame member, toward a (e.g., cut) end of the first frame member, or both, as examples.

In various embodiments, the first frame member includes a first engagement member 30 between the first section and the second section of the first frame member 10. Further, in a number of embodiments, the first frame member includes a first engagement member 30 between the third section and the second section of the first frame member 10. Various embodiments include both such first engagement members 30, for example, on opposite (e.g., right and left) sides of the apparatus. Further still, in a number of embodiments that include the first and/or second engagement member 30, the (e.g., each) engagement members 30 include a first bend or elbow in the first frame member, wherein the bend in the first frame member 10 forming the engagement member 30 is at least 90 degrees. and no more than 120 degrees. In certain embodiments, the angle is at least 45 degrees and no more than 135 degrees.

In a number of embodiments of an apparatus 1, the second section of the first frame member 10 is opposite the first end of the third frame member 16. Further, in various embodiments, the second section of the first frame member 10 is diagonally opposite the first end of the third frame member 16. Still further, in some embodiments, the first section of the first frame member 10 has a cut end, for example, opposite the second section of the first frame member 10.

In various embodiments, the frame assembly 2 bends (e.g., plastically deforms) rather than breaking when an excessive force is applied to the frame frame assembly 2. The fabric body 102 may constrain the direction and amount of bending of the frame assembly 2. For example, in a number of embodiments, when the apparatus is in an upright position on a flat surface and an excessive force is applied to a top of the apparatus 1, the frame assembly 2 bends rather than breaking. Further, in various embodiments, the frame assembly 2 bends rather than buckling when an excessive force is applied to the frame assembly 2. Buckling meaning the frame assembly 2 collapses in a non-controlled manner. For example, in a number of embodiments, when the apparatus 1 is in an upright position on a flat surface and an excessive force is applied to a top of the apparatus 1, the frame assembly 2 bends rather than buckling.

In a number of embodiments, the apparatus is configured to stand up, for example, when uncollapsed or when opened. The embodiment shown in FIG. 1, for example, is standing upright in an uncollapsed or open configuration and is configured to stand up in this configuration.

As mentioned, in a number of embodiments, the apparatus includes a fabric body 102. Further, in various embodiments, the apparatus further includes sleeves, for example, in the fabric body, for instance, that contain the frame assembly 2. In certain embodiments, for example, the apparatus includes sewn sleeves in the fabric body 102 that contain the frame assembly 2. Still further, in a number of embodiments, the fabric body 102 increases the load bearing capacity of the apparatus 1 including the frame assembly 2, for example, by supporting the frame assembly 2 and potentially constraining the movement, bending, and flexing of the longitudinal arms and transverse members. For instance, in particular embodiments, the fabric body 102 increases compressive strength of apparatus 1 comprising the frame assembly 2 by supporting the frame assembly 2 against buckling. An example is strength to withstand a vertical load applied downward to the top of the apparatus 1 when the apparatus 1 is sitting on a flat level surface. Another example is strength to withstand being placed down hard on the bottom of the apparatus 1, for example, on a flat level surface, for instance, when the apparatus 1 is (e.g., fully) loaded, such as with a child in the child carrier. In some embodiments, for example, the frame assembly 2 (e.g., at least one frame member 10, 12, or 16) is curved to control direction of the buckling to facilitate increasing the compressive strength of the apparatus 1 by the fabric body 102. In particular embodiments, for instance, the frame assembly 2 or frame member 10, 12, and/or 16 is curved in a substantially common plane with a wall (e.g., side wall) of the fabric body 102, for example. In such a configuration, when the frame assembly 2 or frame member 10, 12, and/or 16 is loaded in compression, the curvature increases and the fabric body 102 resists the increase in curvature by supporting the frame member 10, 12, and 16 along its length. In various embodiments, the frame is within the fabric body 102 or a space defined by panels of the fabric body 102. Even further, in some embodiments, the apparatus includes graphene. Graphene may increase strength, wear resistance, or both, as examples. For instance, in particular embodiments that include fabric (e.g., the fabric body 102), the fabric includes graphene. Further, in certain embodiments that include a strap, the strap includes graphene. Further, certain embodiments include UHMWPE, Spectra, or both, for example, in fabric, straps, or both.

As also mentioned, in some embodiments, the apparatus includes a one or more fastener 100, for example, connected to the fabric body 102. Further, in a number of embodiments, the fastener 100 can be fastened (e.g., by the user) to hold the frame assembly in an (e.g., uncollapsed) configuration, first configuration 4. For instance, in some embodiments, when the frame assembly 2 is expanded (e.g., by the user) to an uncollapsed configuration or first configuration 4, the fastener 100 can be fastened (e.g., by the user) to hold the frame assembly 2 within the fabric body 102 in the uncollapsed configuration. The fastener 100 may be unfastened (e.g., by the user) before the frame assembly 2 is collapsed to the second configuration 3 (e.g., by the user, for instance, to a collapsed configuration). The apparatus 1 may include one or more fasteners 100.

Various embodiments meet certain safety requirements or have certain safety features. In a number of embodiments, for example, the apparatus 1 is certified to conform with ASTM F2549-14aV, EN 13209-12004, or both. Further, in various embodiments, a contact point between two frame members, such as the engagement member 30 (or engagement members 30) of first frame member 10 and second frame member 12, is covered (e.g., with fabric), for example, to protect a child's fingers from getting pinched, hurt, or caught between the two frame members. Even further, in various embodiments, the cover (e.g., fabric) to protect the child's fingers is cone shaped, shaped like a truncated cone, similar to engagement lock member 32, includes a frustum, or a combination thereof. Further still, in some embodiments, the apparatus includes a flap to protect a child's fingers from getting pinched between frame members. Even further still, in various embodiments, the apparatus includes a cover to protect a child's fingers from getting pinched between frame members. In some embodiments, the cover is fabric, but in other embodiments, the cover may be made of, or include, a different material, for example, plastic or polymer. In a number of embodiments, for instance, the cover to protect a child's fingers from getting pinched (e.g., between frame members) is molded.

Some embodiments include wheels or casters, which are not shown but generally known in the art. For example, in a number of embodiments, the apparatus includes two wheels, or at least two wheels, for instance, for rolling the apparatus on a flat surface. For example, in particular embodiments, the apparatus includes two wheels for rolling the apparatus on a flat surface and the two wheels are attached to the third frame member 16, or attached to the apparatus near the third frame member 16, as examples. For instance, in particular embodiments, the two wheels are located near the transverse base 24 of the third frame member 16. Further, in certain embodiments, the two wheels are attached to the transverse base 24 at the second end of the third frame member 16. In other embodiments, the two wheels are attached to the first frame member 10 proximal the transverse base 24, or towards the terminal ends of the longitudinal arms 18.
