Best Mode for Carrying Out the Invention

[0055] In the following description, various aspects of the present disclosure will be described. For purposes of interpretation, specific details are set forth to enable a complete understanding of the present disclosure. It will be apparent to those skilled in the art that the present disclosure has other embodiments with different details without affecting its essence. Therefore, the present disclosure is not limited by the content shown in the accompanying drawings and described in the specification, but is limited only by the content shown in the claims, and the appropriate scope of the present disclosure is determined only by the broadest interpretation of the claims.

[0056] As used herein, when a feature or element is described as being "on another feature or element", the feature or element may be directly on the other feature or element, or there may be intervening features and / or elements. In contrast, when a feature or element is described as being "directly on another feature or element", there are no intervening features or elements. Also, when a feature or element is described as being "connected to", "attached to", or "coupled to" another feature or element, the feature or element may be directly connected to, attached to, or coupled to the other feature or element, but there may also be intervening features or elements. In contrast, when a feature or element is described as being "directly connected to", "directly attached to", or "directly coupled to" another feature or element, there are no intervening features or elements.

[0057] Spatially relative terms, such as "lower", "below", "low", "upper", "above", may be used herein for ease of explanation to describe a positional relationship between one element or feature and another element or feature as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures is inverted, an element or feature described as "lower" than another element or feature will be oriented "above" the other element or feature. Thus, the exemplary term "below" can encompass both the direction of "above" and "below". The device may be oriented in other directions (rotated 90 degrees or other directions), and the spatially relative descriptions used herein will be interpreted accordingly. Similarly, terms such as "above", "below", "vertical", "horizontal", etc. are used herein for descriptive purposes only unless otherwise specified.

[0058] In this specification, the terms "first" and "second" may be used to describe various features or elements, but unless otherwise specified, these features or elements are not limited by these terms. These terms may be used to distinguish one feature or element from another. Thus, the first feature or element described below may be referred to as the second feature or element, and similarly, the second feature or element described below may be referred to as the first feature or element without departing from the scope of this disclosure.

[0059] First aspect: In a first aspect, the present disclosure provides a baby carrier. The baby carrier includes a pouch component and a waist belt. The bottom of the pouch component is selectively connected to the waist belt such that the baby carrier has at least two operating states. The baby carrier according to the first aspect of the present disclosure will be specifically described.

[0060] First embodiment: Figures 1 and 2 show a front view and a rear view of a baby carrier 100 according to a first embodiment of the present invention when worn by a caregiver (shown as a mannequin 9 in the figure). The baby carrier 100 is composed of a pouch part 1, waist belts 2, two shoulder straps 3, and the like.

[0061] Referring to FIG. 1, the pouch component 1 is sheet-shaped and generally made of fabric. The pouch component 1 has an outer surface 11 and an inner surface 12 (see FIG. 4). The outer surface 11 is the surface of the pouch component 1 on the side opposite to the mannequin 9, and the inner surface 12 is the surface of the pouch component 1 on the side opposite to the mannequin 9. In some embodiments, the pouch component 1 is made of a single-layer fabric, and the outer surface 11 and the inner surface 12 are two opposite surfaces of the single-layer fabric. In some other embodiments, the pouch component 1 includes at least two layers of fabric, and the outer surface 11 and the inner surface 12 are made of different fabrics, taking into account the durability of the pouch component 1 and the softness and comfort of the pouch component 1 when contacting an infant or a toddler. In some embodiments, a liner may be filled between the outer surface 11 and the inner surface 12. The liner is formed from, for example, a sponge material, and the liner can provide a cushioning effect.

[0062] Referring to FIG. 1 again, the pouch component 1 has an upper part 1a and a lower part 1b that face each other. The upper part 1a has an upper end 101. The upper end 101 corresponds to the head of the infant. In the case of a smaller-sized infant, when the pouch component 1 is on the caregiver's chest, the infant is adapted to sit in a direction facing the caregiver (backward) within the pouch component 1, and the upper end 101 may be close to the back side of the infant's head. In the case of a larger-sized toddler, when the pouch component 1 is on the caregiver's chest, the toddler is adapted to sit in a direction opposite to the caregiver within the pouch component 1, and the upper end 101 may be located under the toddler's armpit. The lower part 1b is configured to be connected to the waist belt 2 and is configured to support the waist of the infant or the toddler.

[0063] In addition, terms indicating directions such as "up", "down", "upper part", and "bottom part" in the embodiments of the present disclosure refer to the directions in the state where the baby carrier 100 or the pouch component 1 is deployed (as shown in FIGS. 3, 13, and 15, the shoulder strap 3 is shown in the state of being worn by the caregiver). Further, terms indicating directions such as "left", "right", "outer side", and "inner side" in the embodiments of the present disclosure refer to the directions when the baby carrier 100 is worn by the caregiver, as shown in FIGS. 1 and 2. "Left" and "right" correspond to the "left" and "right" of the caregiver, "outer side" corresponds to the direction away from the caregiver, and "inner side" corresponds to the direction facing the caregiver. The terms indicating directions are only intended to make the description of the embodiments of the present invention clearer and are not intended to unduly limit the protection scope of the present invention.

[0064] Referring to FIGS. 1 and 2, the waist belt 2 may be removably or fixedly connected to the bottom 1b of the pouch component 1. The waist belt 2 is wound around the caregiver's waist during use to disperse the weight of the baby onto the caregiver's waist. In combination with related technologies, it is known that the length of the waist belt 2 can be adjusted according to the size of the caregiver's waist. The waist belt 2 is provided with a buckle 6, and both ends of the waist belt 2 are connected by engaging and locking the buckle 6, and both ends of the waist belt 2 are separated by unlocking and disengaging the buckle 6, making it easier for the caregiver to put on and take off the waist belt 2. Refer to FIG. 1. As shown in FIG. 3, in some embodiments, the buckle 6 can include a male buckle 61 and a female buckle 62. The male buckle 61 is adjustably arranged at one end of the waist belt 2, and the female buckle 62 is arranged at the other end of the waist belt 2. The male buckle 61 and the female buckle 62 are removably snap-fastened. In alternative embodiments, the buckle 6 may be implemented in other ways.

[0065] Referring to FIGS. 1 to 3, the first ends of the two shoulder straps 3 are spaced apart from each other and are connected to the left and right ends of the upper end 101 of the pouch component 1. The second ends of the two shoulder straps 3 are wound upward around the two shoulders of the caregiver, and then extend downward and are removably connected to the left and right sides of the pouch component 1 via the buckle 5 respectively. In some embodiments, two connecting lugs 13 extending obliquely upward are provided on the two side surfaces of the pouch component 1, and the two shoulder straps 3 are removably connected to the two connecting lugs 13 via the buckle 5 respectively. In some embodiments, the buckle 5 includes a male buckle 51 and a female buckle 52 corresponding to each other. For example, male buckles 51 are provided at the second ends of the two shoulder straps 3 respectively, and female buckles 52 are provided on the outer surfaces of the two connecting lugs 13 respectively. The corresponding shoulder strap 3 and the corresponding connecting lug 13 are removably connected via the male buckle 51 and the female buckle 52. Since the female buckle 52 is disposed on the outer surface of the connecting lug 13, it is possible to prevent the buckle 5 from directly contacting the infant. Further, each connecting lug 13 extends obliquely upward, which is consistent with the stress direction of each shoulder strap 3 and also helps to fit the pouch component 1 to the infant.

[0066] Referring to FIG. 2, in some embodiments, each shoulder strap 3 is crossed on the caregiver's back and then connected to the connecting lug 13 on the opposite side by the buckle 5. In some alternative embodiments, the two shoulder straps 3 may not be crossed on the caregiver's back and may be directly connected to the connecting lug 13 on the same side by the buckle 5.

[0067] Referring to FIGS. 1, 3, and 4, the bottom 1b of the pouch component 1 is selectively connected to the waist belt 2, whereby the seating height provided to the infant by the pouch component 1 can be adjusted. When the infant sits in the baby carrier 100, the pouch component 1 wraps the infant under the influence of the infant's gravity, and it is understood that the bottom 1b of the pouch component 1 forms a pocket bottom that wraps around the infant's waist. The seat surface height refers to, for example, the height of the lowest position of the pocket bottom with respect to the waist belt 2 (e.g., the upper end 201 of the waist belt 2). When the baby carrier 100 is used for a smaller infant, the pouch component 1 can provide an appropriate seat surface height for the infant and bring the infant's head closer to the caregiver's chest, thus giving the infant a sense of security and comfort. When the baby carrier 100 is used for a larger toddler, the pouch component 1 can provide an appropriate seat surface height for the toddler and prevent the toddler's head from getting too close to the caregiver's head.

[0068] Referring to FIG. 5, in some embodiments, an opening 30 is provided on the inner surface 32 of each shoulder strap 3, and a foldable lining 301 is accommodated in the opening 30. The opening 30 can be opened by the lining 301, whereby the use width W of each shoulder strap 3 is enlarged (see FIG. 4). In some alternative embodiments, the opening 30 may be disposed on the outer surface 31 of each shoulder strap 3. Alternatively, openings 30 may be provided on both the inner surface 32 and the outer surface 31 of each shoulder strap 3, respectively.

[0069] Referring back to FIGS. 3 and 4, in some embodiments, the pouch component 1 is removably connected to the waist belt 2. A first connecting member 411 is provided on the outer surface 11 of the bottom 1b of the pouch component 1, and a first connecting member 412 is provided on the inner surface 12 of the bottom 1b of the pouch component 1. A second connecting member 42 is provided on the inner surface 22 of the waist belt 2. The second connecting member 42 is selectively connected to the first connecting member 411 on the outer surface 11 of the pouch component 1 or the first connecting member 412 on the inner surface 12 of the pouch component 1, and the height of the seating surface provided by the pouch component 1 is adjusted. For how to adjust the height of the seating surface provided by the pouch component 1, please refer to the following description.

[0070] FIGS. 6 to 8 show the structure of the baby carrier 100 in the first operating state. When the baby carrier 100 is in the first operating state, the outer surface 11 of the bottom 1b of the pouch component 1 faces the inner surface 22 of the waist belt 2, and the bottom 1b of the pouch component 1 is removably connected to the second connecting member 42 of the waist belt 2 via the first connecting member 411. Referring to FIG. 6, when the baby carrier 100 is in the first operating state, the bottom 1b of the pouch component 1 is connected to the waist belt 2 in a deployed state.

[0071] FIGS. 9 to 11 show the structure of the baby carrier 100 in the second operating state. When the baby carrier 100 is in the second operating state, the bottom 1b of the pouch component 1 is wrapped around the bottom of the waist belt 2 outside the waist belt 2, and then folded upward, and the first connecting member 412 on the inner surface 12 of the pouch component 1 is removably connected to the second connecting member 42 of the waist belt 2. Referring to FIG. 11, when the baby carrier 100 is in the second operating state, the bottom 1b of the pouch component 1 is connected to the waist belt 2 in a folded state.

[0072] According to the baby carrier 100 provided in the above embodiment, referring to FIG. 7, when the baby carrier 100 is in the first operating state and the waist belt 2 is wound around the waist of the caregiver, the bottom 1b of the pouch component 1 protrudes from the upper end 201 of the waist belt 2 to form a pocket bottom. Therefore, the baby carrier 100 in the first operating state can provide a higher seat surface height and is suitable for the baby to sit on. Referring to FIG. 10, when the baby carrier 100 is in the second operating state and the waist belt 2 is wound around the waist of the caregiver, since the outer surface 21 of the corresponding waist belt 2 is not connected to the inner surface 12 of the pouch component 1 by the connecting member, the bottom 1b of the pouch component 1 protrudes from the lower end 202 of the waist belt 2 to form a pocket bottom. Therefore, the baby carrier 100 in the second operating state can provide a lower seat surface height and can be suitable for the baby to sit on. In this way, on the one hand, the adaptability of the baby carrier 100 to babies or infants in different growth stages is improved, and on the other hand, the economic burden on parents who purchase the baby carrier 100 is reduced.

[0073] Referring back to FIGS. 3 and 4, in some embodiments, the first connecting members 411 and 412 and the second connecting member 42 may be corresponding hook and loop fasteners. For example, the first connecting member 411 and the first connecting member 412 may be loop fasteners, and the second connecting member 42 may be a hook fastener. As described above, the second connecting member 42 is selectively joined to the first connecting member 411 or the first connecting member 412, and the bottom 1b of the pouch component 1 is connected to the waist belt 2.

[0074] Continuing to refer to FIGS. 3 and 4, the first connection member 411 or the first connection member 412 extends in the left-right direction (lateral direction), and for example, has a sufficient width on the inner and outer surfaces of the bottom 1b of the porch component 1. The dimensions of the first connection member 411 and the first connection member 412 are, for example, the same, and the positions on the porch component 1 overlap, for example. In some alternative embodiments, the first connection member 411 and the first connection member 412 may be hook fasteners, and the second connection member 42 may be a loop fastener.

[0075] Also, in other embodiments not shown, the first connection members 411, 412 and the second connection member 42 may be implemented in other ways. For example, the first connection members 411, 412 and the second connection member 42 may be an assembly having a button connection structure or a snap connection structure.

[0076] There are various embodiments for adjusting the height of the seating surface provided to an infant or toddler by the pouch component 1. For example, in some alternative embodiments not shown, a second connecting member 42 is disposed on the outer surface 21 of the waist belt 2, the first connecting member 411 on the outer surface 11 of the pouch component 1 is omitted, and the first connecting member 412 on the inner surface 12 of the pouch component 1 is retained. When the baby carrier 100 is in the first operating state, the first connecting member 412 on the inner surface 12 of the pouch component 1 is removably connected to the second connecting member 42 on the outer surface 21 of the waist belt 2. In this case, the pouch component 1 provides a higher seating surface height. Also, in order to ensure the stability of the connection between the pouch component 1 and the waist belt 2 when the baby carrier 100 is in the first operating state, the pouch component 1 and the waist belt 2 may be connected via an additional connecting member (such as a button, snap button, hook, etc.). When the baby carrier 100 is in the second operating state, the bottom 1b of the pouch component 1 is wound around the bottom of the waist belt 2 outside the waist belt 2, then bent upward, wound around the upper part of the waist belt 2, and then bent downward, and the first connecting member 412 on the inner surface 12 of the pouch component 1 is removably connected to the second connecting member 42 on the outer surface 21 of the waist belt 2. In this case, the pouch component 1 provides a lower seating surface height.

[0077] In the above embodiments, the seating height provided by the pouch component 1 is adjusted so that the baby carrier 100 can adapt to the seating requirements of infants or toddlers at different growth stages. In some alternative embodiments, the effective use length of the pouch component 1 may be adjusted to adapt to the seating requirements of infants or toddlers at different growth stages. The effective use length refers to, for example, the length between the separation position where the bottom 1b of the pouch component 1 does not contact the caregiver's abdomen and the upper end 101 of the pouch component 1 when the waist belt 2 is wound around the caregiver's waist and the infant or toddler is sitting in the baby carrier 100.

[0078] In some embodiments not shown, the above-described baby carrier 100 may be modified to be able to adjust the effective use length of the pouch component 1. For example, a first connecting member 411 is provided on the outer surface 11 of the pouch component 1, and a first connecting member 412 is provided on the inner surface 12 of the pouch component 1. The second connecting member 42 is disposed on the outer surface 21 of the waist belt 2. The baby carrier 100 has a first operating state and a second operating state. When the baby carrier is in the first operating state, the first connecting member 412 on the inner surface 12 of the pouch component 1 is connected to the second connecting member 42 on the outer surface 21 of the waist belt 2. In this case, the bottom 1b of the pouch component 1 is in a deployed state, and the pouch component 1 has a first effective use length (substantially equal to the length between the upper end 201 of the waist belt 2 and the upper end 101 of the pouch component 1). Also, in order to ensure the stability of the connection between the pouch component 1 and the waist belt 2 when the baby carrier 100 is in the first operating state, the pouch component 1 and the waist belt 2 may be connected via an additional connecting member (such as a button, a snap fastener, a hook, etc.). When the baby carrier 100 is in the second operating state, the bottom 1b of the pouch component 1 is wound around the bottom of the waist belt 2 inside the waist belt 2, and then folded upward, and the first connecting member 411 on the outer surface 11 of the pouch component 1 is connected to the second connecting member 42 on the outer surface 21 of the waist belt 2. In this case, the bottom 1b of the pouch component 1 is in a folded state, and the pouch component 1 has a second effective use length (substantially equal to the length between the upper end 201 of the waist belt 2 and the upper end 101 of the pouch component 1). The second effective use length is shorter than the first effective use length. The first effective use length is suitable for infants with a larger build, and the second effective use length is suitable for infants with a smaller build.

[0079] Second Embodiment: FIG. 12 shows a baby carrier according to a second embodiment of the present invention. The baby carrier of this embodiment is different from that of the first embodiment in the method of adjusting the effective use length of the pouch part 1. The pouch part 1 is detachably connected to the waist belt 2 in the same manner as in the first embodiment. The difference is that at least two third connecting members 43 are arranged on the outer surface 11 of the bottom 1b of the pouch part 1 along the height direction H. A fourth connecting member 44 is provided on the inner surface 22 of the waist belt 2 (not shown in FIG. 12, see FIG. 9). The fourth connecting member 44 is selectively and removably connected to one of at least two third connecting members 43. The fourth connecting member 44 is connected to a higher third connecting member 43, and it can be seen that the effective use length of the pouch part 1 becomes shorter. In the baby carrier 100 shown in FIG. 12, the height direction H coincides with the direction of the effective use length of the pouch part 1. In some alternative embodiments, at least two third connecting members 43 may be arranged on the inner surface 12 of the pouch part 1, and the fourth connecting member 44 may be arranged on the outer surface 21 of the waist belt 2. The mounting of the third connecting member 43 and the fourth connecting member 44 can be obtained with reference to the first connecting members 411 and 412 and the second connecting member 42. Details will not be described again here.

[0080] Continuing to refer to FIG. 12, in some embodiments, when the fourth connecting member 44 of the waist belt 2 is connected to a third connecting member 43 that is not at the bottom, the pouch part 1 under the waist belt 2 is folded upward and folded with respect to the pouch part 1. In some embodiments, the pouch part 1 may further include a first positioning mechanism 15. The first positioning mechanism 15 is configured to keep the pouch part 1 in a folded state, which helps to keep the appearance of the baby carrier 100 neat.

[0081] Continuing to refer to FIG. 12, in some embodiments, the first positioning mechanism 15 can include a removably connected first positioning member 151 and a second positioning member 152. The first positioning member 151 may be disposed on the outer surface 11 of the pouch component 1, and the second positioning member 152 may be disposed on the outer surface 21 of the waist belt 2. When the fourth connecting member 44 on the inner surface 22 of the waist belt 2 is connected to the third connecting member 43 other than the bottom on the outer surface 11 of the pouch component 1, the lower end 102 of the pouch component 1 is wound around the bottom of the waist belt 2, folded upward, and the first positioning member 151 and the second positioning member 152 are removably connected. The first positioning member 151 and the second positioning member 152 may be hook and loop fasteners (such as Velcro (registered trademark)), snap fasteners, or magnetic members, but are not limited thereto. In alternative embodiments, the first positioning mechanism 15 may be implemented in other ways.

[0082] Third Embodiment: FIGS. 13 and 14 show a baby carrier according to a third embodiment of the present invention. In the baby carrier of this example, the effective use length of the pouch component 1 is adjusted in a different way from the above embodiments. Similar to the above embodiments, the pouch component 1 is removably connected to the waist belt 2. At least two channels 130 extending in the lateral direction are provided at the bottom 1b of the pouch component 1. The at least two channels 130 are sequentially arranged in the height direction H, and the waist belt 2 selectively passes through one of the at least two channels 130. It is understood that when the waist belt 2 passes through a higher channel 130, the effective use length L of the pouch component 1 becomes shorter.

[0083] In some embodiments, when the waist belt 2 passes through the non-bottom channel 130, the pouch component 1 under the waist belt 2 is folded upward and is folded with respect to the pouch component 1. Referring to FIG. 14, the pouch component 1 may further include a first positioning mechanism 15. The first positioning mechanism 15 is configured to maintain the pouch component 1 in a folded state. The first positioning mechanism 15 may include, for example, a first positioning member 151 and a second positioning member 152 that are removably connected. The first positioning member 151 and the second positioning member 152 are, for example, arranged at a distance from each other in the height direction on the inner surface 12 of the pouch component 1. When the waist belt 2 passes through the non-bottom channel 130, the bottom end 102 of the pouch component 1 is folded upward, and the first positioning member 151 and the second positioning member 152 are removably connected. The first positioning member 151 and the second positioning member 152 may be a hook and loop fastener, a snap fastener, or a magnetic member, but are not limited thereto. In an alternative embodiment, the first positioning mechanism 15 may be implemented in other ways.

[0084] Fourth Embodiment: Figures 15 to 17 show a baby carrier according to a fourth embodiment of the present invention. In the baby carrier of this embodiment, the effective use length of the pouch component 1 is adjusted in a different way from the above embodiment. Different from the above embodiment, the pouch component 1 is fixedly connected to the waist belt 2. More specifically, the lower end 102 of the pouch component 1 is connected to the upper end 201 of the waist belt 2. The baby carrier 100 has a third operating state and a fourth operating state. When the baby carrier 100 is in the third operating state, the pouch component 1 and the waist belt 2 are in a deployed state, and the pouch component 1 has a first effective use length L1. When the baby carrier 100 is in the fourth operating state, the lower end 202 of the waist belt 2 is folded upward and detachably connected to the pouch component 1, and the pouch component 1 has a second effective use length L2. The first effective use length L1 is longer than the second effective use length L2. The baby carrier 100 in the third operating state is suitable for infants of a larger size, and the baby carrier 100 in the fourth operating state is suitable for infants of a smaller size.

[0085] Referring to FIGS. 16 and 17, in some embodiments, when the baby carrier 100 is in the fourth operating state, the lower end 202 of the waist belt 2 is detachably connected to the pouch component 1 via the second positioning mechanism 16. The second positioning mechanism 16 is configured to maintain the baby carrier 100 in the fourth operating state, and the pouch component 1 provides safe and stable support for the infant.

[0086] The second positioning mechanism 16 is implemented in various ways. Refer to FIGS. 16 and 17. As shown in FIG. 17, in some embodiments, the second positioning mechanism 16 can include a first zipper 161, a second zipper 162, and a zipper head 163. The first zipper 161 is disposed on the inner surface 12 of the pouch component 1, the second zipper 162 is disposed at the lower end 202 of the waist belt 2, and the first zipper 161 and the second zipper 162 are removably connected via the zipper head 163. The distance L3 between the first zipper 161 and the lower end 102 of the pouch component 1 (which is also the upper end 201 of the waist belt 2) is greater than or equal to the distance L4 between the upper end 201 and the lower end 202 of the waist belt 2. Further, the pouch component 1 is further provided with a cover flap 164 configured to cover the first zipper 161. The cover flap 164 can prevent discomfort caused by direct contact between the first zipper 161 and the second zipper 162. A zipper is attached between the zipper structure and the infant or toddler. Further, in some alternative embodiments, the first zipper 161 can be disposed, for example, on the outer surface 11 of the pouch component 1. Further, in some alternative embodiments, the second positioning mechanism 16 can be implemented in various ways including, but not limited to, corresponding hook and loop fasteners, snap fasteners, or magnetic members.

[0087] The baby carrier 100 provided in the first aspect of the present invention includes a pouch component 1 and a waist belt 2. The bottom of the pouch component 1 is selectively connected to the waist belt 2 to adjust the seat height provided by the pouch component 1 and / or the effective use length of the pouch component 1. Thus, the baby carrier 100 can adapt to the seating requirements of infants or toddlers at different growth stages.

[0088] The fifth embodiment: Figures 18 to 23 show the structure of the baby carrier 100 according to the fifth embodiment of the present invention. The baby carrier 100 includes a pouch portion 1, a waist belt 2, two shoulder straps 3, etc., similar to the first to fourth embodiments described above.

[0089] Referring to FIGS. 18 and 19, the pouch component 1 is, for example, sheet-shaped and includes two opposite surfaces, namely an outer surface 11 and an inner surface 12. When the baby carrier 100 is worn by a caregiver, the outer surface 11 basically faces away from the caregiver, and the inner surface 12 basically faces the caregiver. The pouch component 1 is usually made of fabric. Of course, the material of the pouch component 1 is not limited to fabric. In some embodiments, the pouch component 1 is made of a single-layer fabric, and the outer surface 11 and the inner surface 12 are two opposite surfaces of the single-layer fabric. In other embodiments, the pouch component 1 may include one or more layers of fabric. In this example, a two-layer fabric is taken as an example. The fabric layer where the outer surface 11 is located and the fabric layer where the inner surface 12 is located may be made of the same material or different materials in consideration of different requirements such as the durability of the pouch component 1, the softness and comfort of the contact position between the pouch component 1 and the infant or toddler. Depending on the embodiment, a liner may be filled between the outer surface 11 and the inner surface 12. The liner is made of, for example, a relatively common resin sponge material or a soft filler such as sponge, and the liner can provide a cushioning effect.

[0090] Referring to FIG. 18 again, the pouch component 1 has an upper part 1a and a lower part 1b that are opposite to each other vertically. The upper part 1a has an upper end 101. The upper end 101 corresponds to the head of the infant. In the case of a smaller-sized infant, when the pouch component 1 is on the infant's back, the infant is adapted to sit in the pouch component 1 in a direction facing the caregiver (backward), and the upper end 101 may be near the back of the infant's head. In the case of a larger-sized toddler, when the pouch component 1 is on the toddler's chest, the toddler is adapted to sit in the pouch component 1 in a direction not facing the caregiver (forward), and the upper end 101 may be located under the toddler's armpit. The lower part 1b is configured to be connected to the waist belt 2 and is configured to support the waist of the infant or toddler.

[0091] Figures 20 to 23 show a front view and a corresponding partial cross-sectional view of the baby carrier 100 in different operating states. The waist belt 2 is selectively connected to the pouch component 1 to provide different operating states for the baby carrier 100. In different operating states, the baby carrier 100 has different shapes to adapt to the seating requirements of infants or toddlers at different stages. The waist belt 2 is in a closed loop shape during use, wrapped around the caregiver's waist to distribute the weight of the infant to the caregiver's waist. In combination with the prior art, it is well known that the length of the waist belt 2 can be adjusted according to the size of the caregiver's waist. In some embodiments, a buckle 6 is provided on the waist belt 2. The buckle 6 is snapped or unlocked to facilitate the caregiver's attachment and detachment of the waist belt 2. Referring to FIG. 20, in some embodiments, the buckle 6 can include a male buckle 61 and a female buckle 62. The male buckle 61 is adjustably disposed at one end of the waist belt 2, and the female buckle 62 is disposed at the other end of the waist belt 2. The male buckle 61 and the female buckle 62 are removably snapped together. In some alternative embodiments, the buckle 6 may be implemented in other ways. Further, in some alternative embodiments, the waist belt 2 may be adjusted in length in other ways. For example, the waist belt 2 can adjust its own length through the cooperation of a tri-glide button or a stair button and the webbing.

[0092] Referring to FIG. 20, the first ends of the two shoulder straps 3 are spaced apart from each other and are connected to the left and right ends of the upper end 101 of the pouch component 1. The second ends of the two shoulder straps 3 are wound upward around the two shoulders of the caregiver and then extend forward and are removably connected to the left and right sides of the pouch component 1 via the buckle 5 respectively. In some embodiments, two connecting lugs 13 extending obliquely upward are provided on the two side surfaces of the pouch component 1, and the two shoulder straps 3 are removably connected to the two connecting lugs 13 via the buckle 5 respectively.

[0093] As shown in FIG. 20, in some embodiments, the buckle 5 includes, for example, a male buckle 51 and a female buckle 52 corresponding to each other. For example, male buckles (first fastening members) 51 are provided at the second ends of the two shoulder straps 3 respectively, and female buckles (second fastening members) 52 are provided on the outer surfaces of the two connecting protrusions 13 respectively. The corresponding shoulder strap 3 and the corresponding connecting protrusion 13 are detachably connected via the male buckle 51 and the female buckle 52. Since the female buckle 52 is arranged on the outer surface of the connecting lug 13, the buckle 5 can be prevented from directly contacting the infant. Further, each connecting lug 13 extends obliquely upward and supports the force along the extending direction of each shoulder strap 3, which also helps to fit the pouch component 1 to the infant or toddler. In some embodiments, each shoulder strap 3 crosses on the caregiver's back and is then connected to the connecting lug 13 on the opposite side by the buckle 5. In some alternative embodiments, the two shoulder straps 3 may not cross on the caregiver's back and may be directly connected to the connecting lug 13 on the same side by the buckle 5.

[0094] Referring to FIGS. 20 and 22, in some embodiments, the pouch component 1 includes a main body portion 10a and a first passage portion 131 located at the bottom of the main body portion 10a, and the waist belt 2 is adapted to pass through the first passage portion 131. Referring to FIG. 20, the first passage portion 131 is not folded with respect to the main body portion 10a of the pouch component 1, which corresponds to the first operating state of the baby carrier 100. As will be described later, the baby carrier 100 in the first operating state is suitable for infants of a larger size. Referring to FIG. 22, the first passage portion 131 is folded with respect to the main body portion 10a of the pouch component 1, which corresponds to the second operating state of the baby carrier 100. As will be described later, the baby carrier 100 in the second operating state is suitable for infants of a smaller size.

[0095] Referring back to FIGS. 18 and 19, in some embodiments, a second display portion 72 is disposed on the outer surface 1311 of the first passage portion 131 (the outer surface 1311 belongs to a part of the outer surface 11). The second display portion 72 is, for example, close to the upper end 1301 of the first passage portion 131. A third display portion 73 is provided on the inner surface 1312 of the first passage portion 131 (the inner surface 1312 belongs to a part of the inner surface 12). The third display portion 73 is, for example, close to the lower end of the first passage portion 131, that is, the lower end 102 of the port component 1. The second display portion 72 and the third display portion 73 are spaced apart in the height direction H of the port component 1. Referring to FIGS. 20 and 22, a first display portion 71 is provided on the outer surface 21 of the waist belt 2, and the first display portion 71 is close to the upper end 201 of the waist belt 2. The operating state of the baby carrier 100 is shown by the correspondence between the first display portion 71 and the second display portion 72 or the third display portion 73. Thereby, the caregiver can quickly adjust the baby carrier 100 to an appropriate operating state according to the body type of the infant. In normal use, the waist belt 2 generally has a clear outer surface 21 and an inner surface 22. For example, in some embodiments, the side surface of the waist belt 2 connected to the female buckle 62 via a webbing is the outer surface 21, and the other side surface of the waist belt 2 is the inner surface 22. In this way, when the male buckle 61 and the female buckle 62 are engaged, the waist belt 2 in normal use has a portion sandwiched between the buckle 6 and the caregiver's body, and the buckle 6 can be prevented from directly contacting the caregiver.

[0096] Referring to FIGS. 20 and 21, when the baby carrier 100 is worn by the caregiver in the first operating state, the first passage portion 131 is deployed with respect to the main body portion 10a of the pouch component 1. The waist belt 2 passes through the first passage portion 131, and the first display portion 71 on the outer surface 21 of the waist belt 2 faces the second display portion 72 on the outer surface 1311 of the first passage portion 131. Since there is no portion of the main body portion 10a of the pouch component 1 sandwiched between the waist belt 2 and the caregiver, the pouch component 1 has a longer effective use length L5. The effective use length L5 is suitable for the body type of a relatively large infant, and in this case, the baby carrier 100 is suitable for an infant.

[0097] Referring to FIGS. 22 and 23, when the baby carrier 100 in the second operating state is worn by the caregiver, the first passage portion 131 is folded with respect to the main body portion 10a of the pouch component 1. The outer surface 1311 of the first passage portion 131 faces the caregiver, and the inner surface 1312 faces away from the caregiver. The waist belt 2 passes through the first passage portion 131, and the first display portion 71 on the outer surface 21 of the waist belt 2 faces the third display portion 73 on the inner surface 1312 of the first passage portion 131. Since there is no portion of the main body portion 10a of the pouch component 1 sandwiched between the waist belt 2 and the caregiver (that is, because the first passage portion 131 is pressed against the main body portion 10a), the effective use length L6 of the pouch component 1 is shortened. The effective use length L6 is suitable for the body type of a smaller-sized infant, and can increase the sitting height of the infant without causing a risk of suffocation to the infant. In this case, the baby carrier 100 is suitable for a smaller-sized infant.

[0098] The first display unit 71, the second display unit 72, and the third display unit 73 are a pattern, text, a color block, or any combination thereof, but are not limited thereto. However, such display units are useful for a caregiver to quickly determine the operating state of the baby carrier 100 through the correspondence relationship between the first display unit 71 and the second display unit 72 or the third display unit 73. In some embodiments, the first display unit 71 is, for example, an arrow pattern, the second display unit 72 is, for example, a color block (e.g., white), and the third display unit 73 is, for example, a color block (e.g., purple). In some alternative embodiments, the first display unit 71 is, for example, an arrow pattern, and the second display unit 72 and the third display unit 73 are, for example, text. The text may be, for example, "large" and "small".

[0099] Note that the effective use length of the pouch component 1 is, for example, the length between the separation position where the bottom 1b of the pouch member 1 does not contact the caregiver's abdomen when the waist belt 2 is wound around the caregiver's waist and the baby is sitting in the baby carrier 100, and the upper end 101 of the pouch component 1. In the first operating state shown in FIG. 20 and the second operating state shown in FIG. 22, the separation position where the bottom 1b of the pouch component 1 does not contact the caregiver's abdomen is close to the upper end 201 of the waist belt 2. Also, the pouch component 1 in FIGS. 20 and 22 has substantially the same shape as the pouch component 1 in FIGS. 20 and 22, but the pouch component 1 in FIGS. 20 and 22 has substantially the same shape as the pouch component 1 in FIGS. 20 and 22. FIG. 22 is shown as a plan view. When a baby or an infant sits in the baby carrier 100, it can be seen that the pouch component 1 is affected by the gravity of the baby or the infant and wraps around the baby or the infant, and after the bottom 1b of the pouch component 1 moves away from the caregiver's abdomen, it begins to bend and forms a pocket bottom that wraps around the waist of the baby or the infant.

[0100] Referring back to FIGS. 20 and 22, the width of the main body portion 10a of the port component 1 does not have to be uniform. Thus, when the baby carrier 100 is in the first operating state and the second operating state, the effective use width of the bottom 1b of the port component 1 is not equal so as to better conform to the requirements of the body type of the infant. The effective use width of the bottom 1b of the port component 1 refers to, for example, the distance in the left-right direction S at the separation position where the bottom 1b of the port component 1 does not contact the caregiver's abdomen when the waist belt 2 is wound around the caregiver's waist and the infant is sitting in the baby carrier 100. The effective use width of the bottom 1b of the port component 1 can be understood to correspond to the distance at which the port component 1 separates the infant's both feet. In the first operating state shown in FIG. 20, the port component 1 has an effective use width S1. In the second operating state shown in FIG. 22, the port component 1 has an effective use width S2. The effective use width S2 is smaller than the effective use width S1.

[0101] The first passage portion 131 and the waist belt 2 may be detachably connected via a positioning mechanism 17. The positioning mechanism 17 is configured to limit the relative position between the first passage portion 131 and the waist belt 2, and prevent inconvenience when observing the correspondence between the first display portion 71 and the second display portion 72 or the third display portion 73 due to the relative slide between the waist belt 2 and the first passage portion 131.

[0102] Referring to FIGS. 21 and 23, in some embodiments, the positioning mechanism 71 includes, for example, snap buttons 171 and 173 that are attached to the first passage portion 131 and face each other, and a snap button 172 that is attached to the waist belt 2. Referring to FIG. 21, when the baby carrier 100 is in the first operating state, the snap button 172 can engage with the snap button 171. Referring to FIG. 23, when the baby carrier 100 is in the second operating state, the snap button 172 can engage with the snap button 173. Of course, the implementation of the positioning mechanism 71 is not limited to the above example. For example, the positioning mechanism 71 can include magnetic buckles attached to the first passage portion 131 and the waist belt 2, or can include buttonholes disposed in the first passage portion 131 and buttons attached to the waist belt 2.

[0103] In the above-described embodiment, the position of the second display unit 72 is close to the upper end 1301 of the first passage portion 131, the position of the third display unit 73 is close to the lower end of the first passage portion 131, and the position of the first display unit 71 is close to the upper end 201 of the waist belt 2. However, in reality, the positions of the first display unit 71 to the third display unit 73 are not limited to the above description. For example, in other embodiments, the position of the second display unit 72 is close to the lower end of the first passage portion 131, the position of the third display unit 73 is close to the upper end 1301 of the first passage portion 131, and the first display unit 71 is close to the lower end 202 of the waist belt 2. Further, in other embodiments, the first display unit 71 may be disposed at an appropriate position on the inner surface 22 of the waist belt 2. For example, the second display unit 72 may be disposed on the inner surface 1312 of the first passage portion 131, and the third display unit 73 may be disposed on the outer surface 1311 of the first passage portion 131. In this case, in the first operating state, the first passage portion 131 is opened with respect to the main body portion 10a of the pouch component 1, and the first display unit 71 faces the second display unit 72 located on the inner surface 1312 of the first passage portion 131. When the baby carrier 100 is in the second operating state, the first passage portion 131 is folded with respect to the main body portion 10a of the pouch component 1, the outer surface 1311 of the first passage portion 131 faces the caregiver, and the first display unit 71 faces the third display unit 73 located on the outer surface 1311 of the first passage portion 131.

[0104] Sixth Embodiment: FIGS. 24 and 25 show a front view and a rear view of a baby carrier 100 according to a sixth embodiment of the present invention. The baby carrier 100 is a modified example of the baby carrier 100 according to the fifth embodiment of the present invention shown in FIGS. 18 to 23, and mainly differs from the baby carrier 100 according to the fifth embodiment in the arrangement positions of the first display unit 71 to the third display unit 73. The structure of the baby carrier 100 can be understood without contradiction by referring to the description of the fifth embodiment above. Hereinafter, the main differences from the fifth embodiment will be mainly described.

[0105] Referring to FIG. 24, the first display unit 71 is disposed on the outer surface 1311 of the first passage portion 131, close to the upper end 1301 of the first passage portion 131. The first display unit 71 protrudes, for example, from the left end of the first passage portion 131. The second display unit 72 is disposed on the outer surface 21 of the waist belt 2, close to the upper end 201 of the waist belt 2. The third display unit 73 is disposed on the inner surface 22 (see FIG. 2) of the waist belt 2, close to the lower end 202 of the waist belt 2. The second display unit 72 and the third display unit 73 are spaced apart in the height direction of the waist belt 2 (i.e., the height direction H of the pouch component 1).

[0106] When the baby carrier 100 is in the first operating state, the first passage portion 131 is deployed with respect to the main body portion 10a of the pouch component 1, and the waist belt 2 passes through the first passage portion 131. In this case, the first display unit 71 corresponds to the second display unit 72. When the baby carrier 100 is worn by the caregiver in the first operating state, there is no portion of the main body portion 10a of the pouch component 1 sandwiched between the waist belt 2 and the caregiver, and the effective use length L5 of the pouch component 1 becomes longer. The effective use length L5 is suitable for the body type of a large-sized infant, and the baby carrier 100 in this case is suitable for an infant.

[0107] Referring to FIG. 25, when the baby carrier 100 is in the second operating state, the first passage portion 131 is folded with respect to the main body portion 10a of the pouch component 1, the outer surface 1311 of the first passage portion 131 faces the caregiver side, the inner surface 1312 faces the side opposite to the caregiver side, and the waist belt 2 passes through the first passage portion 131. In this case, the first display unit 71 corresponds to the third display unit 73. When the baby carrier 100 is worn by the caregiver in the second operating state, the main body portion 10a of the pouch component 1 has a portion sandwiched between the waist belt 2 and the caregiver (i.e., the first passage portion 131 is pressed against the main body portion 10a), and the effective use length L6 of the pouch component 1 becomes shorter. The effective use length L6 is suitable for the body type of a smaller infant, and the baby carrier 100 in this case is suitable for an infant.

[0108] Of course, the positions of the first display unit 71, the second display unit 72, and the third display unit 73 on the first passage portion 131 and the waist belt 2 are not limited to the above example. However, based on these positions, the caregiver can quickly determine the operating state of the baby carrier 100 and determine whether it is necessary to adjust the operating state of the baby carrier 100 according to the needs of the baby being cared for. For example, in some alternative embodiments, the first display unit 71 is disposed on the inner surface of the first passage portion 131, the second display unit 72 is correspondingly disposed on the inner surface 22 of the waist belt 2, and the third display unit 73 is correspondingly disposed on the outer surface 21 of the waist belt 2.

[0109] Seventh Embodiment: FIGS. 26 to 28 show an exploded view of the baby carrier 100 according to the seventh embodiment of the present invention and a front view thereof in different operating states. The baby carrier 100 includes a pouch component 1, a waist belt 2, two shoulder straps 3, and the like. The structure of the components of the baby carrier 100 and the connection relationship between the components can be understood without contradiction by referring to the descriptions of the fifth and sixth embodiments above. Hereinafter, the description will focus on the differences between the baby carrier 100 of this embodiment and the baby carriers 100 of the fifth and sixth embodiments described above.

[0110] Referring to FIG. 26, a second passage portion 132 is provided at the bottom 1b of the pouch component 1. The second passage portion 132 functions in the same manner as the first passage portion 131 of the fifth and sixth embodiments, that is, both allow the waist belt 2 to pass through. The second passage portion 132 is provided with a first positioning member 1501 and two first adjusting members 1502. The first positioning member 1501 is located at the center of the second passage portion 132, and the two first adjusting members 1502 are respectively arranged at both ends of the second passage portion 132. The waist belt 2 is provided with a second positioning member 251 and four second adjusting members 252. The second positioning member 251 is located at the center of the four second adjusting members 252, and the four second adjusting members 252 are respectively arranged in two at both ends of the second passage portion 132. The first positioning member 1501 is configured to be detachably connected to the second positioning member 251, and the two first adjusting members 1502 are configured to be selectively connected to the four second adjusting members 252.

[0111] FIG. 27 is a front view of the baby carrier 100 in the first operating state. Referring to FIGS. 26 and 27 together, the waist belt 2 passes through the second passage portion 132, the first positioning member 1501 engages with the second positioning member 251, and the two first adjusting members 1502 respectively engage with the two outermost second adjusting members 252. In this case, the second passage portion 132 is fully deployed, and the effective use width of the bottom 1b of the pouch component 1 is widened. The effective use width is approximately equal to the length S3 of the second passage portion 132. FIG. 28 is a front view of the baby carrier 100 in the second operating state. Different from the above-described first operating state, the two first adjusting members 1502 are respectively connected to the two innermost second adjusting members 252. In this case, the second passage portion 132 is contracted to provide a narrow effective use width of the bottom 1b of the pouch component 1, and this effective use width is approximately equal to the length S4 of the contracted second passage portion 132. The effective use width S4 is smaller than the effective use width S3. It is understood that when the baby carrier 100 is worn by the caregiver in the first operating state, the wide effective use width S3 is suitable for infants of a larger size. It is understood that when the baby carrier 100 is worn by the caregiver in the second operating state, the narrower effective use width S4 is suitable for infants of a smaller size.

[0112] In the above embodiment, the first positioning members 1501, the two first adjusting members 1502, the second positioning member 251, and the four second adjusting members 252 are described as examples. However, in actual applications, their numbers are not limited to the above examples. For example, in some alternative embodiments, the numbers of the first positioning member 1501 and the second positioning member 251 may each be two or more, the number of the first adjusting members 1502 on the same side of the first positioning member 1501 may be two or more, and the number of the second adjusting members 252 on the same side of the second positioning member 251 may be three or more. It is understood that the bottom 1b of the porch component 1 can provide two or more effective use widths by reasonably setting the numbers and positions of the first adjusting member 1502 and the second adjusting member 252 and selectively connecting the first adjusting member 1502 and the second adjusting member 252. Accordingly, the baby carrier 100 has two or more operating states. In this way, the baby carrier 100 can better adapt to the seating requirements of infants or toddlers of various body types.

[0113] Eighth Embodiment: FIGS. 29 to 31 show an exploded view of the baby carrier 100 according to the eighth embodiment of the present invention and a front view thereof in different operating states. The baby carrier 100 includes a porch component 1, a waist belt 2, two shoulder straps 3, and the like. The structure of the components of the baby carrier 100 and the connection relationship between the components can be obtained without contradiction by referring to the descriptions of the fifth to seventh embodiments above. The differences between the baby carrier 100 of this embodiment and the baby carriers 100 of the fifth to seventh embodiments above will be mainly described below.

[0114] Referring to FIG. 29, a passage through which the waist belt 2 passes is not provided at the bottom 1b of the port component 1. On the left side of the port component 1, two first connection members 45 are arranged, and the two first connection members 45 are arranged in order in the height direction H of the port component 1. On the right side of the bottom 1b of the port component 1, two second connection members 46 are arranged, and the two second connection members 46 are arranged in order in the height direction H of the port component 1. The waist belt 2 includes a first portion 2a and a second portion 2b that are separated from each other, rather than the entire connection band. A third connection member 47 is provided at one end of the first portion 2a, and the third connection member 47 is selectively connected to one of the two first connection members 45. A fourth connection member 48 is provided at one end of the second portion 2b, and the fourth connection member 48 is selectively connected to one of the two second connection members 46. In some embodiments, the other end of the first portion 2a and the other end of the second portion 2b are removably connected via a buckle 6. In some alternative embodiments, the waist belt 2 can include the entire connection band connected between the third connection member 47 and the fourth connection member 48. The entire connection band may be, for example, an elastic band or a webbing having an adjustable buckle (e.g., a trigger slide button). Of course, the implementation of the waist belt 2 is not limited to the above example as long as the third connection member 47 and the fourth connection member 48 are separated from each other.

[0115] Referring to FIG. 30, the third connection member 47 is removably connected to the lower connection member 45 of the two first connection members 45, and the fourth connection member 48 is removably connected to the lower connection member 46 of the two second connection members 46. The first connection member 45 connected to the third connection member 47 and the second connection member 46 connected to the fourth connection member 48 are basically at the same height, which corresponds to the first operating state of the baby carrier 100. When the baby carrier 100 is worn by the caregiver in the first operating state, the port component 1 has a longer effective use length L5. The effective use length L5 is adapted to the body type of a relatively large infant, and in this case, the baby carrier 100 is suitable for the infant.

[0116] Referring to FIG. 31, the third connecting member 47 is detachably connected to the upper connecting member 45 among the two first connecting members 45, and the fourth connecting member 48 is detachably connected to the upper connecting member 46 among the two second connecting members 46. The first connecting member 45 connected to the third connecting member 47 and the second connecting member 46 connected to the fourth connecting member 48 are basically at the same height, which corresponds to the second operating state of the baby carrier 100. When the baby carrier 100 is worn by the caregiver in the second operating state, the porch component 1 has a shorter effective use length L6. The effective use length L6 is adapted to the body shape of a smaller-sized infant. In this case, the baby carrier 100 is suitable for the infant.

[0117] As can be seen from FIGS. 30 and 31, the width (the distance in the left-right direction) between the first connecting member 45 and the second connecting member 46 at the same height is substantially equal to the effective use width of the bottom 1b of the porch component 1 at that position. In some embodiments, the width between the first connecting member 45 and the second connecting member 46 on the left and right of the porch component 1 changes according to the height, providing different effective use widths for the bottom 1b of the porch component 1. For example, the width S6 between the first connecting member 45 and the second connecting member 46 located above at the same height is smaller than the width S5 between the first connecting member 45 and the second connecting member 46 located below at the same height. Thus, when the baby carrier 100 is worn by the caregiver in the first operating state, the effective use length L5 of the porch part 1 becomes longer, and at the same time, the effective use width S5 of the bottom 1b of the porch part 1 becomes wider, making it more suitable for the body shape of an infant. Also, when the baby carrier 100 is worn by the caregiver in the second operating state, the effective use length L6 of the porch part 1 becomes shorter, and at the same time, the effective use width S6 of the bottom 1b of the porch part 1 becomes narrower, making it more suitable for the body shape of a smaller-sized infant.

[0118] Referring to FIG. 29, in some embodiments, the first connecting member 45 and the third connecting member 47 may be two chain straps that fit together to form a zipper, and the first connecting member 45 extends, for example, along the height direction H of the pouch component 1. The second connecting member 46 and the fourth connecting member 48 may be two chain straps that fit together to form a zipper, and the second connecting member 46 extends, for example, along the height direction H of the pouch component 1. Of course, the first to fourth connecting members are not limited to zippers as long as they can be removably connected. For example, in some alternative embodiments, the first connecting member 45 and the third connecting member 47 may be snap fasteners or hook-and-loop fasteners that fit together, and the second connecting member 46 and the fourth connecting member 48 may be snap fasteners or hook-and-loop fasteners that fit together.

[0119] Referring to FIG. 31, in some embodiments, when the third connecting member 47 and the fourth connecting member 48 of the waist belt 2 are connected to the first connecting member 45 and the second connecting member 46 that are not at the bottom, the pouch component 1 under the waist belt 2 is folded upward and folded with respect to the pouch component 1. In some embodiments, the pouch component 1 may further include a positioning mechanism 18. The positioning mechanism 18 is configured to keep the pouch component 1 in a folded state, which helps to keep the appearance of the baby carrier 100 neat.

[0120] Continuing to refer to FIG. 31, in some embodiments, the positioning mechanism 18 can include at least one positioning member 181 and at least one positioning member 182. When the third connecting member 47 and the fourth connecting member 48 of the waist belt 2 are connected to the first connecting member 45 and the second connecting member 46 that are not at the bottom, the lower end 102 of the pouch component 1 is bent upward, and the positioning member 181 and the positioning member 182 are removably connected. In some embodiments, the positioning member 181 is disposed above the positioning member 182 and between the upper first connecting member 45 and the second connecting member 46, and the positioning member 182 is disposed, for example, between the lower first connecting member 45 and the second connecting member 46. The positioning member 181 and the positioning member 182 may be hook-and-loop fasteners, snap fasteners, or magnetic members, but are not limited thereto. Of course, in some alternative embodiments, the positioning mechanism 18 may be implemented in other ways.

[0121] In addition, in the above embodiments, the number of the first connecting member 45 and the second connecting member 46 is two each. In practice, however, the number of the first connecting member 45 and the second connecting member 46 is not limited to two, and may be three or more. The plurality of first connecting members 45 and the plurality of second connecting members 46 are sequentially arranged in the height direction H of the pouch component 1. The third connecting member 47 is selectively connected to one of the plurality of first connecting members 45, and the fourth connecting member 48 is selectively connected to one of the plurality of second connecting members 46. In this way, the baby carrier 100 has two or more operating states and can better adapt to the seating requirements of infants of various body types.

[0122] The ninth embodiment: Figures 32 to 36 show the structure of the baby carrier 100 according to the ninth embodiment of the present invention. The baby carrier 100 includes a pouch component 1, a waist belt 2, two shoulder straps 3, and the like. The structure of each component of the baby carrier 100 and the connection relationship between each component can be understood without contradiction by referring to the descriptions of the fifth to eighth embodiments above. Hereinafter, the description will focus on the differences between the baby carrier 100 of this embodiment and the baby carriers 100 of the fifth to eighth embodiments above.

[0123] Referring to FIGS. 32 and 33, two passage portions, i.e., a third passage portion 133 and a fourth passage portion 134, are laminated on the bottom 1b of the pouch component 1. That is, the third passage portion 133 and the fourth passage portion 134 are at the same height. In some embodiments, the third passage portion 133 is located outside the fourth passage portion 134, and the length S8 of the third passage portion 133 is greater than the length S7 of the fourth passage portion 134. The waist belt 2 can selectively pass through the third passage portion 133 or the fourth passage portion 134 to put the baby carrier 100 in different operating states.

[0124] Referring to FIG. 34, when the waist belt 2 passes through the third passage portion 133 and the third passage portion 133 and the fourth passage portion 134 are deployed with respect to the main body portion 10a of the pouch component 1, this corresponds to the first operating state of the baby carrier 100. When the baby carrier 100 is worn by the caregiver in the first operating state, there is no portion of the main body portion 10a of the pouch component 1 sandwiched between the waist belt 2 and the caregiver, and the effective use length L5 of the pouch component 1 becomes longer. At the same time, the effective use width of the bottom 1b of the pouch component 1 is approximately equal to the length S8 of the third passage portion 133. In this case, the baby carrier 100 is suitable for infants with a larger build.

[0125] Referring to FIG. 35, the waist belt 2 passes through the fourth passage portion 134, and the third passage portion 133 and the fourth passage portion 134 are deployed with respect to the main body portion 10a of the pouch component 1, which corresponds to the second operating state of the baby carrier 100. When the baby carrier 100 is worn by the caregiver in the second operating state, the pouch component 1 has a longer effective use length L5, and the effective use width of the bottom 1b of the pouch component 1 is substantially equal to the length S7 of the fourth passage portion 134. In this case, the baby carrier 100 is suitable for a baby of a smaller size.

[0126] Referring to FIG. 36, the waist belt 2 passes through the fourth passage portion 134, and the third passage portion 133 and the fourth passage portion 134 are folded with respect to the main body portion 10a of the pouch component 1. The outer surface 1331 of the third passage portion 133 (see FIG. 33, the outer surface 1331 belongs to a part of the outer surface 11) faces the caregiver, and the inner surface 1342 of the fourth passage portion 134 (see FIG. 33, the inner surface 1342 belongs to a part of the inner surface 12) faces the caregiver, corresponding to the third operating state of the baby carrier 100. When the baby carrier 100 is worn by the caregiver in the third operating state, there is a portion of the main body portion 10a of the pouch component 1 sandwiched between the waist belt 2 and the caregiver, and the effective use length L7 of the pouch component 1 becomes shorter. At the same time, the effective use width of the bottom 1b of the pouch member 1 becomes smaller than the length S8 of the third passage portion 133. In this case, the baby carrier 100 is also suitable for a baby of a smaller size.

[0127] Referring again to FIGS. 32 to 36, the waist belt 2 and the passage portion through which the waist belt 2 passes are detachably connected via a positioning mechanism 19. The positioning mechanism 19 is configured to limit the relative position between the waist belt 2 and the passage portion through which the waist belt 2 passes, and to prevent operational inconveniences caused by the waist belt 2 slipping relative to the passage portion. In some embodiments, as shown in FIG. 32, the positioning mechanism 19 may include a positioning member 191 attached to the wall of the passage portion and a positioning member 192 attached to the waist belt 2. The positioning member 191 and the positioning member 192 are detachably engaged. In some embodiments, the positioning member 191 and the positioning member 192 may be snap fasteners, magnetic members, or corresponding hook and loop fasteners, but are not limited thereto.

[0128] In the above embodiment, an example in which two passage portions (the third passage portion 133 and the fourth passage portion 134) are stacked on the bottom portion 1b of the pouch component 1 has been described. However, in reality, three or more passage portions may be stacked on the bottom portion 1b of the pouch component 1. The lengths of the passage portions sequentially increase or sequentially decrease in the direction from the outer surface 11 to the inner surface 12 of the pouch component 1. Since the waist belt 2 selectively passes through one of the plurality of passage portions, the baby carrier 100 has a plurality of operating states.

[0129] Tenth Embodiment: FIGS. 37 and 38 show the structure of the baby carrier 100 according to the tenth embodiment of the present invention. The baby carrier 100 includes a pouch component 1, a waist belt 2, two shoulder straps 3, and the like. The structure of each component of the baby carrier 100 and the connection relationship between each component can be understood without contradiction by referring to the descriptions of the fifth to ninth embodiments described above. Hereinafter, the description will focus on the differences between the baby carrier 100 of this embodiment and the baby carriers 100 of the fifth to ninth embodiments described above.

[0130] Referring to FIGS. 37 and 38, at the bottom 1b of the pouch component 1, at least two laterally extending channels 130 are provided. The at least two channels 130 are sequentially arranged in the height direction H. The waist belt 2 selectively passes through one of the at least two channels 130. Thereby, the baby carrier 100 has different operating states. It can be understood that when the waist belt 2 passes through the higher channel 130, the effective use length L of the pouch component 1 becomes shorter.

[0131] In some embodiments, when the waist belt 2 passes through a channel 130 that is not the bottommost one, a part of the pouch component 1 below the waist belt 2 is folded upward and folded with respect to the pouch component 1. Referring to FIG. 38, the pouch component 1 may further include a positioning mechanism 15. The positioning mechanism 15 is configured to maintain the pouch component 1 in a folded state. The positioning mechanism 15 may include, for example, a positioning member 151 and a positioning member 152 that are removably connected. The positioning member 151 and the positioning member 152 are, for example, arranged at a distance from each other in the height direction on the inner surface 12 of the pouch component 1. When the waist belt 2 passes through a non-bottom channel 130, the lower end 102 of the pouch component 1 is folded upward, and the positioning member 151 and the positioning member 152 are removably connected. The positioning member 151 and the positioning member 152 are, for example, hook and loop fasteners, snap fasteners, magnetic members, etc., but are not limited thereto. In alternative embodiments, the positioning mechanism 15 may be implemented in other ways.

[0132] Continuing to refer to FIGS. 37 and 38, the waist belt 2 is removably connected to the channel 130 through which the waist belt 2 passes, for example, via a positioning mechanism 15a. The positioning mechanism 15a is configured to limit the relative position between the waist belt 2 and the channel 130 through which the waist belt 2 passes, and prevent operational inconveniences caused by the slipping of the waist belt 2 relative to the channel 130. In some embodiments, as shown in FIGS. 37 and 38, the positioning mechanism 15a can include a positioning member 15a1 attached to the wall of the channel 130 and a positioning member 15a2 attached to the waist belt 2. The positioning member 15a1 and the positioning member 15a2 are removably connected. In some embodiments, the positioning member 15a1 and the positioning member 15a2 may be, but are not limited to, snap fasteners, magnetic members, or corresponding hook and loop fasteners. The positioning member 15a1 may be attached at any suitable position of the channel 130, including but not limited to the middle position and the end position of the channel 130.

[0133] Example 11: FIGS. 39 to 43 show the structure of the baby carrier 100 according to the 11th embodiment of the present invention. The baby carrier 100 includes a porch part 1, a waist belt 2, two shoulder straps 3, etc. The structure of each component of the baby carrier 100 and the connection relationship between each component can be understood without contradiction by referring to the description of the 5th to 10th embodiments above. Hereinafter, the description will focus on the differences between the baby carrier 100 of this embodiment and the baby carrier 100 of the 5th to 10th embodiments above.

[0134] Referring to the front view of the baby carrier 100 shown in FIG. 39, male buttons (first fastening members) 51 are provided on each shoulder strap 3, and two female buttons (second fastening members) 52 are arranged on both the left and right sides of the pouch component 1. The first fastening member 51 is removably connected to the corresponding second fastening member 52, and the shoulder strap 3 is configured to form a closed loop. In some embodiments, the two second fastening members 52 may be fixed at appropriate heights on the two side edges of the main body 10a of the pouch component 1 via, for example, a strip 521 or other suitable structure. The connection lugs 13 described above may not be provided on both side surfaces of the pouch component 1. A passage portion 135 is provided at the bottom 1b of the main body 10a of the pouch component 1, and the waist belt 2 passes through this passage portion 135. In some embodiments, a buckle 6 may be provided on the waist belt 2. The buckle 6 is snap-fastened or unlocked so that the caregiver can easily attach and detach the waist belt 2.

[0135] When wearing the baby carrier, in the state shown in FIG. 39, it is worn by the caregiver, the buckle 6 is fastened, the waist belt 2 is wound around the caregiver's waist, the first fastening member 51 and the second fastening member 52 are fastened, and the shoulder belt 3 is hung on the caregiver's shoulders. The passage portion 135 is deployed with respect to the main body 10a of the pouch component 1, and a part of the main body 10a between the two second fastening members 52 is fully deployed. This corresponds to the first operating state of the baby carrier 100. In this case, since there is no portion of the main body 10a of the pouch component 1 sandwiched between the waist belt 2 and the caregiver, the effective use length L5 of the pouch component 1 becomes longer and the effective use width S9 becomes wider. The effective use width S9 is approximately equal to the distance between the two side edges of the pouch member 1 at the two second fastening members 52. The effective use length L5 and the effective use width S9 are adapted to the body type of a large-sized infant, and in this case, the baby carrier 100 is suitable for the infant.

[0136] Referring to the rear view of the baby carrier 100 shown in FIG. 40, a restricting member 13a is provided on the inner surface 12 of the pouch component 1, and the two second fastening members 52 adjust the left-right distance between the pouch components 1 by changing the left-right distance between them via the restricting member. In this example, the restricting member includes, for example, a pair of restricting members. More specifically, the pair of restricting members are a pair of belt loops 13a. The pair of belt loops 13a are spaced apart between the two second fastening members 52. Referring to FIG. 41, each second fastening member 52 can pass through the adjacent belt loop 13a, whereby the left-right distance between the two second fastening members 52 is shortened, and the left-right distance between the pouch components 1 is shortened. When the baby carrier is worn by the caregiver in the state shown in FIG. 41, the pouch component 1 has a longer effective use length L5 and a narrower effective use width S10. The effective use width S10 is approximately equal to the left-right distance between the pair of belt loops 13a. This corresponds to the second operating state of the baby carrier 100. When the baby carrier 100 is in the second operating state, the baby carrier 100 is more suitable for thinner and taller infants or toddlers.

[0137] Note that, depending on the embodiment, the number of belt loops 13a of the pouch component 1 is not limited to one pair. For example, two or more pairs of belt loops 13a may be spaced apart between the two second fastening members 52. Each second fastening member 52 is configured to selectively pass through the corresponding belt loop 13a among any pair of belt loops 13a, and the left - right distance between the two second fastening members 52 can be changed according to the body type of the infant, thereby changing the left - right distance between the pouch component 1. Also, depending on the embodiment, the arrangement position of the belt loop 13a is not limited to the inner surface 12 of the pouch component 1. For example, the belt loop 13a may be arranged on the outer surface 11 of the pouch component 1, or the belt loop 13a may be arranged on both the inner surface 12 and the outer surface 11 of the pouch component 1. According to other embodiments, the pouch component 1 is not provided with a belt loop 13a, and the left - right distance of the pouch component 1 is adjusted by another limiting member. Specifically, a pair of first limiting members (for example, male snap fasteners) are arranged on the inner surface 12 of the pouch component 1, and a pair of second limiting members (for example, female snap fasteners) corresponding to the first limiting members can also be provided on the strip 521 of each second fastening member 52. In this way, the two second fastening members 52 can change the left - right distance of the pouch component 1 via the limiting members (that is, the first limiting member and the second limiting member), specifically, the left - right distance between the two second fastening members 52 can be changed.

[0138] Referring to FIGS. 41 and 42, the waist belt 2 is removably connected to the passage portion 135, for example, via the positioning mechanism 19a. The positioning mechanism 19a is configured to limit the relative position between the waist belt 2 and the passage portion 135, and prevent operational inconveniences caused by the slippage of the waist belt 2 relative to the passage portion 135. In some embodiments, as shown in FIG. 42, the positioning mechanism 19a can include a positioning member 19a1 attached to the wall of the passage portion 135 and a positioning member 19a2 attached to the waist belt 2. The positioning member 19a1 and the positioning member 19a2 are removably connected. In some embodiments, the positioning member 19a1 and the positioning member 19a2 may be snap fasteners, magnetic members, or corresponding hook and loop fasteners for each other, but are not limited thereto. In some embodiments, the positioning member 19a1 is disposed at one or both ends of the passage portion 135, which is convenient for the caregiver to reach into the passage portion 135 to release the connection relationship between the positioning member 19a1 and the positioning member 19a2. Of course, the installation position of the positioning member 19a1 is not limited to the end of the passage portion 135.

[0139] Referring to the rear view of the baby carrier 100 shown in FIG. 43, after the passage portion 135 is folded with respect to the main body portion 10a of the port component 1, the waist belt 2 passes through the passage portion 135, and at the same time, each second fastening member 52 passes through the adjacent belt loop 13a. This corresponds to the third operating state of the baby carrier 100. When the baby carrier 100 is worn by the caregiver in the third operating state, the main body portion 10a of the port component 1 has a portion sandwiched between the waist belt 2 and the caregiver, and the effective use length L8 of the port component 1 becomes shorter. At the same time, the effective use width S10 of the port component 1 becomes narrower. In this case, the baby carrier 100 is suitable for a smaller-sized infant.

[0140] Second aspect: In a second aspect, the present disclosure provides a baby carrier. The baby carrier includes a pouch component, a waist belt, and a height adjustment assembly. The pouch component includes an outer sheet and an inner sheet that define a seating space for an infant or toddler. The outer sheet has a first upper end, and connecting bands that extend upward are disposed at the left and right ends of the first upper end, respectively, and a first engaging member is provided on each connecting band. The inner sheet has a second upper end, and the bottom of the inner sheet and the bottom of the outer sheet are joined to form the bottom of the pouch component, and the bottom of the pouch component is configured to support the waist of the infant or toddler. The waist belt is connected to the inner sheet. The first ends of the two shoulder straps are spaced apart from each other and connected to the second upper end, and the second ends of the two shoulder straps are connected to the left and right sides of the outer sheet, respectively. A second engaging member is provided on each shoulder strap, and the second engaging member is removably engaged with the corresponding first engaging member. The height adjustment assembly is disposed on at least one of the inner sheet and the two shoulder straps and is configured to change the height of the second upper end relative to the first upper end. The baby carrier according to the third aspect of the present disclosure will be specifically described below through several examples.

[0141] Example 12: Figures 44 to 51 show a baby carrier 300 according to the twelfth embodiment of the present invention. The baby carrier 300 mainly includes a pouch component 310, a waist belt 320, two shoulder straps 330, and a height adjustment assembly 345. Figures 44 and 45 show a front view and a side perspective view of the baby carrier 300 when it is worn by a wearer (shown as a mannequin 9 in the figure) and is in a normal use state. When the baby carrier 300 is in a normal use state, an infant or a young child can be safely wrapped in the seating space 340 of the pouch component 310, and the wearer such as a caregiver can use both hands freely. In the use state shown in Figures 44 and 45, the pouch component 310 wraps the infant or young child in front of the wearer's body. Considering it in combination with the prior art, it can be understood that in a use state not shown, the pouch component 310 may wrap the infant around the wearer's back. Figures 46 and 49 show a front view of the baby carrier 300 when it is in an open state while worn on the mannequin 9. In this case, the infant can be placed inside the pouch component 310, or the infant can be lifted from the pouch component 310 through the upper opening of the pouch component 310.

[0142] Referring to Figures 45 to 48 together, the pouch component 310 includes an outer sheet 311 and an inner sheet 312 that define a seating space 340 for an infant. The outer sheet 311 has a first upper end 3111, and connecting bands 3112 extending upward are respectively arranged at the left and right ends of the first upper end 3111, and a first engaging member 3113 is provided on each connecting band 3112. The inner sheet 312 has a second upper end 3121, and the second upper end 3121 is connected to the first ends 331 of the two shoulder straps 330. The bottom of the inner sheet 312 and the bottom of the outer sheet 311 are joined to form the bottom 313 of the pouch component 310, and the bottom 313 of the pouch component 310 is configured to support the waist of the infant.

[0143] The waist belt 320 is connected to the inner sheet 312 and is wrapped around the waist of the caregiver during use to disperse the weight of the infant onto the waist of the caregiver. Considering it in conjunction with the related art, it is well known that the length of the waist belt 320 can be adjusted according to the size of the caregiver's waist. The waist belt 320 is provided with a buckle (not shown), and both ends of the waist belt 320 are connected by the engagement and locking of the buckle, and both ends of the waist belt 320 are separated by unlocking and disengaging the buckle, making it easier for the caregiver to put on and take off the waist belt 320.

[0144] Referring to FIGS. 45 and 46, the first ends 331 of the two shoulder straps 330 are spaced apart from each other and connected to the second upper end 3121. The second ends 332 of the two shoulder straps 330 are wound upward around the two shoulders of the caregiver and then extend downward and are respectively connected to the left and right sides of the outer sheet 311. A second engaging member 3321 is provided on a part of each shoulder strap 330 on a part of the body in front of the shoulder. The second engaging member 3321 is removably connected to the corresponding first engaging member 3113, and the pouch component 310 forms a pocket-shaped seating space 340. The pocket-shaped seating space 340 ensures the safety of the seating of the infant or toddler and also ensures the comfort of the seating of the infant or toddler. The first engaging member 3113 and the second engaging member 3321 can adopt any suitable structure.

[0145] Referring to FIGS. 44 and 45, in this example, an auxiliary guard 315 can also be provided at the first upper end 3111. The lower end (unnumbered in the figure) of the auxiliary guard 315 is connected to the first upper end 3111, and the auxiliary guard 315 can be deployed or folded along its lower end. Fasteners 3151 are provided on two side surfaces of the auxiliary guard 315, an upper buckle 3159 and a lower buckle 3158 are provided on the outer sheet 311, and the fasteners 3151 can be selectively fastened to the upper buckle 3159 or the lower buckle 3158 to provide different usage modes. For example, when an infant or toddler is facing the caregiver's chest, the fasteners 3151 can be fastened to the upper buckle 3159. In this case, the auxiliary guard 315 can support the back of the infant's head. When the infant or toddler turns their back from the caregiver's chest, the buckle between the fasteners 3151 and the upper buckle 3159 is released, the auxiliary guard 315 rotates downward and outward, the auxiliary guard 315 and the outer sheet 311 overlap, and then the fasteners 3151 are buckled to the lower buckle 3158 to fix the position of the auxiliary guard 315. In this case, the infant's head can be exposed from the first upper end 3111, and the auxiliary guard 315 can be prevented from blocking the infant's field of vision.

[0146] Referring to FIG. 45, a further view is shown of the second ends 332 of the two shoulder straps 330 engaged with the outer sheet 311. Specifically, the two shoulder straps 330 cross behind the caregiver and extend to two sides of the outer sheet 311. The second end 332 of each shoulder strap 330 is connected to a first snap 371 respectively. Connection bands 3157 are provided on two sides of the outer sheet 311 respectively, and a second snap 372 is provided on each connection band 3157. The second snap 372 is removably connected to the first snap 371, and the second ends 332 of the two shoulder straps 330 are connected to the outer sheet 311. In some embodiments, two sides of the inner portion 312 are connected to adjustment straps 360 respectively, and a buckle (e.g., a tri-glide button) 373 is provided at the second end 332 of each shoulder strap 330. The free end of the adjustment strap 360 passes through the tri-glide button 373 of the first snap 371 in turn. That is, each shoulder strap 330 is connected to the first snap 371 via the tri-glide button 373 and the adjustment strap 360. As can be seen from FIG. 45, when the first snap 371 engages with the second snap 372, a space is formed between the connection band 3157 and the bottom of the pouch component 310, allowing the legs of the infant or toddler to stretch. When the first snap 371 is separated from the second snap 372, the second end 332 of the shoulder strap 330 remains connected to the inner sheet 312 via the adjustment strap 360, and the shoulder strap 330 does not fall off while hanging on the caregiver's shoulder. Of course, the method by which the second end 332 of each shoulder strap 330 engages with the outer sheet 311 is not limited to the above example, and other engagement methods can be obtained by referring to the related art. Details will not be described again here.

[0147] Referring to FIGS. 46 and 49, the first engaging member 3113 and the second engaging member 3321 of the baby carrier 300 are separated, and under the influence of gravity, the outer sheet 311 of the pouch part 310 and the two connecting straps 3112 are folded outward and hang down, exposing the height adjustment assembly 345. The height adjustment assembly 345 is configured and constructed to change the height of the second upper end 3121 relative to the first upper end 3111. Referring to FIGS. 47 and 48, it can be understood that when the first engaging member 3113 is connected to the second engaging member 3321, the height of the first upper end 3111 is determined. The position of the bottom 313 of the pouch part 310 (i.e., the height of the seating surface for the infant or toddler) can be raised or lowered by changing the height of the second upper end 3121 relative to the first upper end 3111, adapting to the use of the infant or toddler at various growth stages and improving the comfort of use for the caregiver.

[0148] Referring to FIGS. 46, 49, and 50, in this example, the height adjustment assembly 345 can include a first connection member 341 and a first lift member 351. The first connection member 341 is horizontally connected between two shoulder straps 330 and is disposed on the second upper end 3121. The first connection member 341 may be a soft strip or a hard strip. In some embodiments, the first connection member 341 may be a strip integrated with the adjustment strap 360. The adjustment strap 360 is stitched to the two shoulder straps 330. The portion between the two shoulder straps forms the first connection member 341, and the portions located outside the two shoulder straps 330 are configured to be connected to the first snap 371 and the trigger button 373. It can be understood that the first connection member 341 and the pouch component 310 are located on the same side (the front side in the figure) of the caregiver. More specifically, the first connection member 341 is disposed below the second engagement member 3321. The first end 3511 of the first lift member 351 is connected to the inner seat 312 and is disposed between the two shoulder straps 330. The second end 3512 of the first lift member 351 is removably engaged with the first connection member 341. The first lift member 351 may be, for example, a cloth strap.

[0149] Referring to FIGS. 44, 48, and 49, when the second end 3512 of the first lift member 351 is connected to the first connection member 341, when the infant sits in the seating space 340 of the pouch component 310, due to the pulling effect of the first lift member 351, a part of each shoulder strap 330 located between the first connection member 341 and the second upper end 3121 is folded, the second upper end 3121 is lifted upward relative to the first upper end 3111, the distance H2 between the first upper end 3111 and the bottom 313 becomes shorter, the bottom 313 is lifted upward, and the seating height of the infant relative to the caregiver increases. Thereby, the necks of smaller infants and toddlers are disposed at appropriate positions above the first upper end 3111, making it suitable for smaller infants and toddlers.

[0150] Conversely, referring to FIGS. 44, 46, and 47, when the second end 3512 of the first lift member 351 is separated from the first connection member 341, when an infant sits in the seating space 340 of the porch component 310, a part of each shoulder strap 330 located between the first connection member 341 and the second upper end 3121 is automatically deployed, the second upper end 3121 descends relative to the first upper end 3111, the distance H1 between the first upper end 3111 and the bottom 313 becomes longer, the bottom 313 descends, and the seating height for the caregiver of the infant becomes lower. As a result, the neck of a large-sized infant is disposed at an appropriate position above the first upper end 3111, making it suitable for a large-sized infant.

[0151] In this example, due to the arrangement of the height adjustment assembly 345, on the one hand, the adaptability of the baby carrier 300 to infants or toddlers at different growth stages is improved, and on the other hand, the burden on the caregiver who purchases the baby carrier is reduced.

[0152] Referring to FIGS. 46 and 50, the first connection member 341 is provided with a first positioning member 3401, the second end 3512 of the first lift member 351 is provided with a second positioning member 3402, and the second positioning member 3402 is removably engaged with the first positioning member 3401. The first positioning member 3401 and the second positioning member 3402 may be corresponding hook and loop fasteners, magnetic members, or snap fasteners to each other. Alternatively, among the first positioning member 3401 and the second positioning member 3402, one may be a buttonhole, and the other may be a button or a hook that fits into the buttonhole. Of course, in some embodiments, for example, the first lift member 351 may be directly connected to the first connection member 341 to change the height of the second upper end relative to the first upper end.

[0153] Referring back to FIG. 50, the first connecting member 341 has an outer surface 341a and an inner surface 341b. The outer surface 341a faces away from the caregiver's body, and the inner surface 341b faces the caregiver's body. In this example, the first positioning member 3401 can include a first hook-and-loop fastener 3411 (e.g., Velcro (registered trademark)) disposed on the inner surface 341b of the first connecting member 341. The second positioning member 3402 can include a second hook-and-loop fastener 3422 (e.g., Velcro (registered trademark)). When it is necessary to raise the second upper end 3121, the second end 3512 of the first lifting member 351 is bent inwardly downward along the upper edge of the first connecting member 341, and the second hook-and-loop fastener 3422 is opposed to and connected to the first hook-and-loop fastener 3411. By arranging the first hook-and-loop fastener 3411 and the second hook-and-loop fastener 3422 in this way, it is possible to prevent each hook-and-loop fastener from directly contacting the infant and causing discomfort. In some embodiments, in order to improve the connection strength between the first lifting member 351 and the first connecting member 341, the first positioning member 3401 further includes a third hook-and-loop fastener 3413 disposed on the outer surface 341a of the first connecting member 341, and the second positioning member 3402 may further include a fourth hook-and-loop fastener 3424. When the first hook-and-loop fastener 3411 and the second hook-and-loop fastener 3422 are connected facing each other, the third hook-and-loop fastener 3413 and the fourth hook-and-loop fastener 3424 are connected facing each other.

[0154] FIG. 51 shows a modification of the first embodiment of the present invention. A plurality (two or more) of second positioning members 3402 are provided, and the plurality of second positioning members 3402 are arranged at intervals in a direction from the second end 3512 to the first end 3511 of the first lift member 351. By connecting the first positioning member 3401 to different second positioning members 3402, the height of the second upper end 3121 with respect to the first upper end 3111 can be adjusted, whereby the baby carrier 300 can provide a plurality of seating heights, and the application range of the baby carrier 300 is further expanded.

[0155] The 13th embodiment: FIGS. 52 and 53 show the baby carrier 300 according to the 13th embodiment of the present invention. The baby carrier 300 of this embodiment is mainly different from the baby carrier 300 of the 12th embodiment in the installation of the height adjustment assembly 345. Similarities between this embodiment and the 12th embodiment will not be described in detail here again.

[0156] Referring to FIG. 52, the height adjustment assembly 345 can include a second connection member 342 and a second lift member 352. The second connection member 342 is horizontally connected between the two shoulder straps 330 and is disposed above the second upper end 3121. The second connection member 342 may be a soft strip or a hard strip. In some embodiments, the second connection member 342 may be a strip integrated with the adjustment strap 360. It is understood that the second connection member 342 and the pouch component 310 are arranged on the same side (front side in the figure) of the caregiver. More specifically, the second connection member 342 is disposed below the second engagement member 3321. The first end 3521 of the second lift member 352 is connected to the inner seat 312 and is disposed between the two shoulder straps 330. Between the first end 3521 and the second end 3522 of the second lift member 352, a third positioning member 3403 and a fourth positioning member 3404 are disposed. The second lift member 352 may be, for example, a cloth strap.

[0157] Referring to FIG. 53, when it is necessary to make the height of the second upper end 3121 higher than that of the first upper end 3111, the second end 3522 of the second lift member 352 is wound around the second connecting member 342, the fourth positioning member 3404 and the third positioning member 3403 are removably engaged, and the second lift member 352 forms an annular sleeve 3520 that sleeves the second connecting member 342. When an infant sits in the seating space 340 of the port component 310, due to the lifting action of the second lift member 352, the portion between the second connecting member 342 and the second upper end 3121 of each shoulder strap 330 is folded, the second upper end 3121 is lifted upward relative to the first upper end 3111, and the seating height of the infant increases.

[0158] Conversely, referring to FIG. 52, when it is necessary to make the height of the second upper end 3121 lower than that of the first upper end 3111, the third positioning member 3403 and the fourth positioning member 3404 are separated. When an infant sits in the seating space 340 of the port component 310, the portion between the second continuation member 342 and the second upper end 3121 of each shoulder strap 330 is automatically deployed, the second upper end 3121 descends relative to the first upper end 3111, and the seating height of the infant decreases.

[0159] Referring back to FIGS. 52 and 53, in this example, a plurality of third positioning members 3403 are provided along the longitudinal direction of the second lift member 352. By connecting the fourth positioning member 3404 to different third positioning members 3403, the height of the second upper end 3121 relative to the first upper end 3111 can be adjusted, whereby the baby carrier 300 can provide a plurality of seating heights, and the application range of the baby carrier 300 is further expanded. In other embodiments, a plurality of fourth positioning members 3404 are provided along the longitudinal direction of the second lift member 352, and the height of the second upper end 3121 can be adjusted by connecting the third positioning member 3403 to different fourth positioning members 3404. In other embodiments, a plurality of third positioning members 3403 and a plurality of fourth positioning members 3404 are provided. In this way, when the second upper end 3121 is adjusted to an appropriate height, at least one pair of the third positioning member 3403 and the fourth positioning member 3404 can be connected, and the lifting reliability of the second lift member 352 can be ensured.

[0160] The third positioning member 3403 and the fourth positioning member 3404 may be a hook and loop fastener, a magnetic member, or a snap fastener that fit with each other, or one of the third positioning member 3403 and the fourth positioning member 3404 may be a buttonhole, and the other may be a button or a hook that fits into the buttonhole.

[0161] Example 14: FIGS. 54 and 56 are partial front views of the baby carrier 300 according to the 14th embodiment of the present invention. The baby carrier 300 of this embodiment is mainly different from the baby carrier 300 of the 12th and 13th embodiments in the installation of the height adjustment assembly 345. Similarities between this embodiment and the 12th and 13th embodiments will not be described in detail here again.

[0162] Referring to FIG. 54, the height adjustment assembly 345 can include a fifth positioning member 3405 and a sixth positioning member 3406 on each shoulder strap 330. The fifth positioning member 3405 and the sixth positioning member 3406 are disposed near the first end 331 of the shoulder strap 330 where the fifth positioning member 3405 and the sixth positioning member 3406 are disposed. It is understood that the fifth positioning member 3405 and the sixth positioning member 3406 are disposed on the same side of the caregiver (e.g., the front side). More specifically, the fifth positioning member 3405 and the sixth positioning member 3406 are located under the second engaging member 3321 and are spaced apart longitudinally. The fifth positioning member 3405 and the sixth positioning member 3406 engage removably to change the height of the second upper end 3121, thereby changing the seating height of the infant or toddler.

[0163] Referring to FIGS. 55 and 56, when the fifth positioning member 3405 and the sixth positioning member 3406 are connected, a portion of each shoulder strap 330 between the fifth positioning member 3405 and the sixth positioning member 3406 is folded, the second upper end 3121 is lifted upward relative to the first upper end 3111, and the seating height of the infant increases.

[0164] Conversely, referring to FIG. 54, when the fifth positioning member 3405 and the sixth positioning member 3406 are separated, the portion of each shoulder strap 330 between the fifth positioning member 3405 and the sixth positioning member 3406 is deployed, the second upper end 3121 descends relative to the first upper end 3111, and the seating height of the infant decreases.

[0165] In some embodiments, at least one of the fifth positioning member 3405 and the sixth positioning member 3406 is provided in plurality at a predetermined interval along the longitudinal direction of the shoulder strap 330. Through different connections between the fifth positioning member 3405 and the sixth positioning member 3406, the height of the second upper end 3121 relative to the first upper end 3111 can be adjusted. Therefore, the baby carrier 300 can provide a plurality of seating heights, and the application range of the baby carrier 300 is further expanded.

In some embodiments, for example, a plurality of the sixth positioning members 3406 are provided along the longitudinal direction of the shoulder strap 330, and the height of the second upper end 3121 can be conveniently adjusted by selectively connecting one fifth positioning member 3405 to the plurality of sixth positioning members 3406. In some embodiments, for example, a plurality of the fifth positioning members 3405 are provided along the longitudinal direction of the shoulder strap 330, and the height of the second upper end 3121 can be conveniently adjusted by selectively connecting one sixth positioning member 3406 to the plurality of fifth positioning members 3405. In some other embodiments, a plurality of the fifth positioning members 3405 and a plurality of the sixth positioning members 3406 are provided along the longitudinal direction of the shoulder strap 330, and the plurality of the fifth positioning members 3405 may be selectively connected to the plurality of the sixth positioning members 3406. In this way, when the second upper end 3121 is lifted to different heights, the connection between at least one pair of the fifth positioning member 3405 and the sixth positioning member 3406 can be ensured.

[0167] In other embodiments, the fifth positioning member 3405 and the sixth positioning member 3406 may be corresponding hook and loop fasteners, magnetic members, or snap fasteners to each other. Alternatively, one of the fifth positioning member 3405 and the sixth positioning member 3406 may be a buttonhole, and the other may be a button or a hook that fits into the buttonhole.

[0168] It should be noted that the height adjustment assembly 345 of this embodiment may be applied to the same baby carrier 300 simultaneously with the height adjustment assembly 345 described in the above twelfth embodiment, thirteenth embodiment, or fifteenth embodiment to be described later.
