Description

Baby sling

Technical Field

The present invention relates to a baby carrier called a baby carrier for holding a baby.

Background

The baby carrier can be worn in various wearing forms according to the growth of the baby, the physique of the protector, the use way and the like. Therefore, it is widely used because of its high convenience.

Recently, a baby carrier with an improved structure has been disclosed.

For example, patent document 1 discloses a "baby carrier".

The above-described "infant carrier" is formed in a substantially spindle shape as a whole with both end portions in the longitudinal direction thereof tightened. A protective part for wrapping the infant is provided between both end parts in the longitudinal direction of the infant carrier. The protection part is folded into a corrugated shape and can be freely stretched. Further, a coupling mechanism capable of coupling both end portions in the longitudinal direction is formed at both end portions.

According to the main content disclosed in patent document 1, since the protector is formed in a corrugated shape, the size of the protector covering the infant can be changed according to the physique and movement of the infant loaded thereon.

However, the infant carrier of patent document 1 has the following problems.

The protection portion is formed in a corrugated shape and is stretchable and contractible, but both end portions in the longitudinal direction are connected in a tightened manner. In addition, although the infant carrier is worn in a state of being hung obliquely with respect to the protection portion, when the infant carrier is worn in a state of being hung obliquely by the protector, a portion of the infant carrier, particularly, which corresponds to the flank of the protector, is in close contact with the flank of the protector.

That is, although the protective portion is formed to have a length corresponding to the length between both end portions in the longitudinal direction of the infant carrier, the protective portion in a bellows shape may not be sufficiently expanded in the width direction to a size suitable for the wrapped infant in practice because the protective portion is worn in close contact with the body of the wearer, and may be entangled in the worst case.

Therefore, in a state where the infant is wrapped in the protector, it is conceivable that the head or foot of the infant positioned on both sides in the longitudinal direction of the protector is particularly pressed, and a comfortable state cannot be ensured for both the infant and the protector.

Further, since such a protector portion cannot sufficiently wrap the infant, there is a possibility that the infant cannot be stably held in the infant carrier when a protector wearing the infant carrier assumes, for example, a forward stooping posture.

On the other hand, when the infant carrier is not excessively tightly attached to the body of the infant and is loosely worn, the protector is folded and stretched by the weight of the infant, and the protector is protruded downward.

Therefore, when an infant is wrapped in the protector portion protruding downward, the head and neck and the abdomen are forced to assume an excessively bent posture by the inside of the protector portion.

Further, since the protector cannot be stably worn on the body of the protector, the protector is not comfortable to wear.

The protector may wear the infant carrier by a clasping method in which the protector covers only the back side (hip and back) of the infant, for example, "in-face standing hugging", that is, a clasping method in which the protector is directly in-face with the infant without interposing the protector therebetween.

That is, when a embracing method such as "face-to-face standing embrace" is adopted, the protector is in direct contact with the infant, and the embracing method is performed without interposing the protector between the protector and the infant. Therefore, the protector should always hold the infant in close contact with the infant on its side.

As another document relating to a baby carrier, a "baby band" of patent document 2 is disclosed. The baby holding belt has double layers of inner cloth and outer cloth, and is sewn at the long side to form a ring-shaped object. And the ring-shaped object has a ring for tightening the two pieces of cloth.

The baby band may be used by hanging one side portion of the ring in the circumferential direction of the ring and the sewing portion on the shoulder portion and carrying a baby in the other side portion.

The baby carrying belt in patent document 2 can be formed by stacking the two pieces of cloth as described above, and can be actively widened. This enables the infant to be stably supported.

However, the loop can be easily widened by using two pieces of cloth, but since the two pieces of cloth are merely overlapped, the two pieces of cloth may be displaced from each other when, for example, an infant twists while wearing the loop.

Therefore, conversely, it can be said that there is still a problem in terms of safety of infants. In addition, along with this problem, the protector needs to support the infant from the lower side with at least one arm (see fig. 1 of patent document 2), and the two cloths are likely to be displaced from each other depending on the clasping method, which also causes a problem of restriction of the clasping method.

Disclosure of Invention

Accordingly, an object of the present invention is to provide an infant carrier that can ensure safety of infants and can be comfortably used by both a protector and an infant.

According to the invention of claim 1, the present invention provides an infant sling which is integrally formed of a sheet-like member and has a holding portion for wrapping an infant and a shoulder-engaging portion engageable with a shoulder of a wearer, wherein the holding portion is formed to have stretchability; an opening portion in which an infant can be taken out of and put into the holding portion is formed at an upper end portion of the holding portion; an expansion/contraction limiting mechanism for limiting expansion/contraction of the opening edge is formed at the opening edge of the opening portion.

An example of the method for forming the sheet-like member, particularly the wrapping portion, to have stretchability is forming the sheet-like member by a woven fabric.

Specifically, the holding portion may be formed by other forming methods capable of securing stretchability, such as weft knitting, warp knitting (tricot), and the like.

The holding portion may be formed of a stretchable material such as nylon.

In this way, when the sheet-like member, particularly the holding portion, is formed of a knitted fabric, even if the material is a non-stretchable material, the tissue itself constituting the knitted fabric has stretchability, and therefore the stretchability of the sheet-like member can be ensured.

The holding portion may be formed by using a member having elasticity such as a rubber sheet.

In this way, when the sheet-like member, particularly the holding portion, is formed using a stretchable material, the stretchability of the sheet-like member can be ensured because the material itself is stretchable.

The upper end of the wrapping portion or the sheet-like member is, for example, an edge corresponding to the upper end side in the width direction (vertical direction) of the wrapping portion when the protector wears the baby carrier in a so-called cradle style.

The expansion/contraction restricting means for restricting expansion/contraction of the opening edge may be formed by, for example, a seam (sewn portion). By forming a seam at the opening edge, the expansion and contraction of the portion where the seam is formed can be restricted, and as a result, the expansion and contraction of the opening edge can be restricted.

The seam used for forming the seam can limit the expansion of the opening edge even if a stretchable thread is used.

In this way, when a stretchable thread such as nylon is used, even if the thread is restricted by the stretch restriction mechanism, the thread at the restricted portion can be appropriately stretched to absorb the stretching force acting on the thread, thereby preventing the thread from being broken.

When the seam is formed, the seam may be formed in a state where the opening edge is formed in a shape of a seam to be described later, or in a state where wrinkles (plets) are formed.

Further, the present invention also includes a stretch regulating mechanism formed by thermally deforming the edge of the opening by applying heat thereto. Further, the expansion limiting mechanism comprises an expansion limiting mechanism formed by performing knurling processing or sewing on the edge of the opening.

According to the present invention, since the holding portion is formed to be stretchable, when the infant is wrapped, the shape thereof is stretchable in accordance with the body shape and physical constitution of the infant. Therefore, the holding part can be closely attached to the body of the infant and the protector, and can stably wrap the infant even if the infant twists.

Further, with the above configuration, even when the infant stands inside the holding portion, the holding portion can be extended to increase the depth inside the holding portion. Therefore, the infant can be protected and prevented from falling to the outer side of the holding part.

In addition, with the above configuration, the infant does not feel a sense of pressure inside the holding portion.

In addition, the wearer can easily attach the infant in the holding portion to his or her body.

Therefore, the burden of the wearer holding the infant can be suppressed as much as possible, and the stability of the infant accommodated in the holding portion can be increased.

Further, a stretch regulating mechanism is formed at an opening edge of the opening portion. Therefore, the expansion and contraction of the opening edge can be restricted so that the opening edge does not excessively stretch or relax.

Therefore, the holding portion is stretchable, and the opening portion thereof can be kept from being excessively opened, so that the infant does not fall through the opening portion.

According to the invention of claim 2, the baby carrier is preferably formed in a double-layer structure by annularly forming the sheet-like member with a single piece of stretchable fabric and folding the sheet-like member over at a widthwise intermediate portion thereof.

By forming the sheet-like member into a ring shape using a single stretchable fabric, it is possible to easily wear the sheet-like member by obliquely hanging the sheet-like member without connecting or disconnecting the sheet-like member with a connecting member such as a buckle (buckle) when putting on or taking off the sheet-like member.

Further, since the sewn portion is not formed in the covering portion, and the intermediate portion in the width direction of the sheet-like member is folded back to form a double-layer structure, the extension and contraction of the covering portion is not hindered by the sewn portion.

Therefore, the holding portion can be flexibly expanded and contracted according to the body shape of the infant, and the comfort of the infant in the holding portion can be further increased.

Further, since the sheet-like member is also present on the side facing the protector by the holding portion, not only the back side of the infant but also the side facing the protector is covered. Therefore, for example, the infant can be prevented from being displaced from and falling off between the protector and the holding portion.

Further, according to the invention of claim 3, it is preferable that the length of the opening edge is formed shorter than the length of the sheet-like member in the circumferential direction.

In this way, by making the length of the opening edge shorter than the length of the sheet-like member in the circumferential direction, the size of the opening can be kept small even if the holding portion is extended. Therefore, the infant in the holding part can be wrapped and prevented from falling from the opening part.

Here, as a preferable configuration for making the length of the opening edge shorter than the length of the sheet-like member in the circumferential direction, for example, the expansion/contraction regulating means for regulating the expansion/contraction of the opening edge is formed by sewing.

Further, even if the predetermined portion of the opening edge is formed by alternately repeating the valley fold and the mountain fold and the wrinkle is formed by sewing the alternately folded portion, the length of the opening edge can be made short.

Further, the fastener may be configured by including a long member such as a tape (tape), a belt (belt), or a rubber string, a fixing mechanism such as a buckle (buckle), a hook (hook), a snap (snap), a hook-and-loop fastener, a zipper, or a button, or a combination thereof.

When the expansion/contraction restricting means for restricting expansion/contraction of the opening edge is formed by the above-described chain links or the pleats, the expansion/contraction of the opening edge can be restricted while the circumferential length of the sheet-like member is kept short.

Further, when the stretch regulating means is formed by a chain fold or a wrinkle, it is not necessary to provide another member for regulating stretch, and only a part of the edge of the opening is basically sewn and can be easily formed.

Further, according to the invention of claim 6, in the baby carrier, an expansion/contraction restricting mechanism for restricting expansion/contraction between the holding portion and the shoulder coupling portion may be formed between the holding portion and the shoulder coupling portion in the circumferential direction of the sheet-like member.

The expansion/contraction restricting means for restricting expansion/contraction between the holding portion and the shoulder connecting portion may include means for forming a seam (sewn portion), or forming the opening edge by applying a hemming process or sewing, or further applying heat to the opening edge to thermally deform the opening edge, or the like, in the same manner as the expansion/contraction restricting means for restricting expansion/contraction of the opening edge.

In this way, by forming the expansion/contraction restricting mechanism for restricting the expansion/contraction of the sheet-like member in the circumferential direction between the bag portion and the shoulder coupling portion, it is possible to restrict the portion between the bag portion and the shoulder coupling portion from being excessively expanded when the sheet-like member is hung obliquely, particularly when a load is likely to act. This prevents the holding portion from being displaced downward, and prevents the baby carrier from being deformed or damaged.

The expansion/contraction restricting mechanism for restricting expansion/contraction between the bag portion and the shoulder coupling portion can more preferably restrict expansion/contraction of the sheet-like member by the expansion/contraction restricting mechanism at each of the upper and lower end portions, particularly when the sheet-like member is formed on the upper end portion side (open end portion side) and the lower end portion side (folded side in the width direction of the sheet-like member) between the bag portion and the shoulder coupling portion.

Wherein the expansion/contraction restricting means for restricting expansion/contraction of the opening edge is formed at the opening edge between the shoulder connecting portion and the holding portion in the circumferential direction of the sheet-like member; the expansion/contraction restricting mechanism for restricting expansion/contraction of the opening edge may restrict expansion/contraction between the holding portion and the shoulder coupling portion of the sheet-like member from an upper end side therebetween.

Further, according to the invention of claim 7, the baby carrier is preferably formed such that a width between the holding portion and the shoulder coupling portion in the circumferential direction of the sheet-like member gradually decreases from the holding portion to the shoulder coupling portion.

In this case, the shoulder joint portion can be formed to fit the width of the shoulder of the wearer, and therefore, the shoulder joint portion can be easily hooked on the shoulder, and a good wearing state can be obtained, and the wearer can wear the shoulder joint portion with good appearance.

Further, by forming the width between the holding portion and the shoulder joint portion in the circumferential direction of the sheet-like member to be gradually reduced, it is possible to avoid a load from being applied to only one portion in a concentrated manner.

In addition, according to the invention of claim 8, in the baby carrier, when a portion corresponding to the front body of the wearer and a portion corresponding to the back body of the sheet-like member overlap each other, the two portions of the sheet-like member are formed into symmetrical shapes that substantially coincide with each other as a whole.

When formed in this way, the front part of the wearer can be brought into close contact with each part of the back part. This also improves the stability of the infant accommodated in the holding portion.

Further, according to the invention of claim 9, in the infant sling, a sewn portion is preferably formed in the shoulder connecting portion of the sheet-like member, and the shoulder connecting portion includes a shoulder pad.

In this way, since the sewn portion is formed in the shoulder joint portion of the sheet-like member, the shoulder joint portion can be restricted from being excessively expanded and contracted. In addition, the shoulder joint portion, which is particularly susceptible to load, can be reinforced.

In addition, in the case of manufacturing the baby carrier, the planar sheet member is formed into a ring shape, and in this case, the sheet member may be sewn to the shoulder joint portion to form a ring shape.

In this way, by forming the sewn portion in the shoulder joint portion, a portion corresponding to the front body and a portion corresponding to the rear body in the sheet-like member can be formed to coincide with each other, and the sheet-like member can be formed as a constituent member of a common sheet-like member.

Therefore, the manufacturing cost and the labor efficiency can be obtained.

Further, even if the sewn portion is formed at the shoulder joint portion, by providing the shoulder pad, when the shoulder joint portion is joined to the shoulder portion, the sewn portion does not locally abut against the shoulder portion, and thus the wearer does not feel uncomfortable, and the wearing comfort can be ensured.

Detailed Description

An embodiment of the present invention will be described below using the drawings.

Fig. 1 shows how a protector wears the baby carrier 11 of this embodiment in a carrying method called "cradle style carrying".

The baby carrier 11 shown in fig. 1 is entirely formed of a sheet-like member 12, and the sheet-like member 12 has a double-layer structure in which the top cloths are stacked. Here, as shown in fig. 2, the outer cloth of the sheet-like member 12 is set as an outer cloth 13, and the inner cloth is set as an inner cloth 14.

The sheet-like member 12 is a knitted fabric formed by combining nylon having elasticity and cotton having a good touch to the skin.

In addition, in manufacturing the baby sling 11, the nylon and cotton can be combined with each other at a stage where they are still fibrous (filimentant) or at a stage where they are linear.

As described above, since the sheet-like member 12 is made of nylon and the entire surface is formed of a knitted fabric, excellent stretchability can be exhibited.

As long as the sheet-like member 12 having excellent stretchability can be formed in this manner, the sheet-like member 12 may be formed using other fibers or threads having excellent stretchability, such as a polyurethane elastic thread.

The sheet-like member 12 may be formed by other methods capable of ensuring stretchability, such as weft knitting such as circular knitting, warp knitting such as tricot knitting, raschel lace (raschel lace), and rib knitting (rib knit).

Further, the sheet-like member 12 may be formed of other materials having a good tactile sensation, such as cashmere (cashmere), wool, and silk, in addition to cotton as described above.

As shown in fig. 2, the baby carrier 11 is formed in a ring shape (cylindrical shape). That is, the infant sling 11 has a fitting insertion opening a through which a protector can be obliquely inserted in the center portion in the axial direction of the annular infant sling 11.

As shown in fig. 3 to 7, the baby carrier 11 has shoulder coupling portions 15, and the shoulder coupling portions 15 have a width such that one portion in the circumferential direction can be coupled to either one of the left and right shoulders of the wearer.

That is, fig. 3 to 7 are a front view, a right side view, a left side view, a top view, and a bottom view of the infant sling 11 in surface contact with each other at a portion facing both sides of the wearing insertion opening a.

The rear view and the front view of the baby carrier 11 are shown as being symmetrical, and therefore, they are omitted.

Further, the baby carrier 11 is provided with holding portions 16 for holding a baby in each of the front and rear portions of the protector when the protector hangs the baby carrier 11 obliquely in the circumferential direction.

As shown in fig. 3, the width between the shoulder connecting portion 15 and the holding portion 16 in the circumferential direction of the baby carrier 11 is formed to gradually decrease from the holding portion 16 to the shoulder connecting portion 15.

The baby sling 11 has an opening B formed at an upper end of the holding portion 16 so as to be openable, and when a protector hangs the baby sling 11 obliquely, the opening B allows an infant to be taken out of and put into the holding portion 16 (see fig. 2).

That is, when the protector wears the baby carrier 11 in the "cradle-style hug" as shown in fig. 1, the upper end edge on the upper end side of the wrapping portion 16 is a portion to be the opening edge 12aa of the opening B.

The opening edge 12aa between the shoulder connecting portion 15 and the wrapping portion 16 in the circumferential direction of the baby carrier 11 is configured as a tuck forming portion 17 as shown in the enlarged partial views of fig. 3 and 4.

The outer sheet 13 and the inner sheet 14 of the sheet-like member 12 corresponding to the front and rear parts of the wearer are formed with the tuck-forming portion 17, and the opening edge 12aa is formed at four positions in total. Each tuck forming section 17 is formed of three tucks 17a, 17b, 17 c.

As shown in fig. 8 and 9, in the sheet-like member 12, grooves are formed at portions corresponding to the darts 17a, 17b, and 17c, so that the entire holding portion 16 can be loosened to form a three-dimensional shape that can easily wrap an infant.

In addition, fig. 8 is a cross-sectional view showing X-X of fig. 3, and fig. 9 is a cross-sectional view showing Y-Y of fig. 3.

The darts 17a, 17b, and 17c may be formed by grasping a part of the opening edge 12aa and sewing the grasped part in a state of overlapping the periphery thereof (see an enlarged view of a main part of fig. 11).

In this way, since the opening edge is tightened, the length of the opening edge is formed shorter than the length of the sheet-like member in the circumferential direction.

However, the opening edge 12aa is not limited to the darts 17a, 17b, and 17c, and may be provided with a long member such as a tape (tape), a belt (belt), or a rubber cord, a fastening means such as a buckle (buckle), a hook (hook), a snap (snap), a hook-and-loop fastener, a zipper, or a button, or a combination thereof. But also heat may be given to thermally deform the opening edge 12 aa. Further, the stretch limiting mechanism may be formed to be stretchable by folding the opening edge 12aa, or alternately repeating valley folding and mountain folding to form a folded shape. Thus, the opening edge 12aa can be provided with a mechanism for restricting the expansion and contraction of the opening without making the opening excessively large.

Next, the form of the baby carrier 11 will be described with reference to fig. 10 to 13, based on the form in which the sheet-like member 12 having the double-layered structure is developed into the one-layered structure, that is, the outer sheet 13 and the inner sheet 14 overlapped with each other are separated from each other.

Fig. 10 is a front view and a rear view showing a state where the infant sling 11 is unfolded, and fig. 11, 12, and 13 are a right view, a top view, and a bottom view showing the infant sling 11. Since the left and right views of the baby sling 11 are the same display, they are omitted.

That is, when the sheet-like member 12 is developed into a one-layer structure from a two-layer structure, the outer sheet 13 and the inner sheet 14 are symmetrical with respect to the middle line portion 18 extending in the vertical direction.

In the step before sewing, the sheet-like member 12 is of course planar, and both ends in the longitudinal direction thereof are sewn together to form the shoulder sewn portions 22, which are in a ring shape as shown in fig. 10 and 12. The shoulder sewn portions 22 are formed at the shoulder joint portions 15 located in the same direction of the sheet-like member 12.

The sheet-like member 12 can be formed by folding the inner sheet 14 toward the inside of the outer sheet 13 with respect to the middle line portion 18.

That is, as described above, the baby carrier 11 can have a double-layer structure in which the same configuration is adopted even when one of the cloths is knitted inside the other cloth, among the cloths on both sides of the center line portion 18. In this way, in the double-layer structure, the outer cloth 13 corresponds to the outer cloth on the outer periphery of the baby back 11 in the ring shape, and the inner cloth 14 corresponds to the inner cloth on the inner periphery.

When the outer sheet 13 and the inner sheet 14 are superposed on each other as described above, the middle line portion 18 of the sheet-like member 12 is positioned at the lower end portion of the baby carrier 11.

The sewn portions 21 are formed on both sides of the intermediate line portion 18 except for the holding portion 16 in the longitudinal direction. The sewn portion 21 is located at the lower end when the sheet member 12 is formed into a double-layer structure, and is therefore set as the lower-end sewn portion 21.

The sewn portion 21 may be sewn or rolled as appropriate. In this way, when the seam portion 21 is formed to be sewn, the outer sheet 13 and the inner sheet 14 can be folded so as to be easily overlapped with each other.

When the sheet-like member 12 is formed in a double-layer structure, the lower-end sewn portion 21 located on the line of the middle line portion 18 is not formed on the lower end side of the covering portion 16 in the circumferential direction of the sheet-like member 12, but is formed particularly on the lower end portion between the shoulder connecting portion 15 and the covering portion 16 (see fig. 3).

The baby carrier 11 of the present embodiment is formed in the above-described shape.

Next, an example of a method for manufacturing the baby carrier 11 in the above-described form will be briefly described with reference to fig. 14.

(1) As shown in fig. 14(a), a sheet-like member 12 formed of a knitted fabric is cut into a rectangular shape (rectangular shape).

(2) As shown in fig. 14(b), the sheet-like member 12 is looped (cylindrical) by sewing the two longitudinal edges 12c, 12d of the sheet-like member 12.

(3) As shown in fig. 14(c), the sheet-like member 12 is folded back at the middle portion line 18 in the width direction (vertical direction). Specifically, the lower half portion in the vertical direction of the sheet-like member 12 is folded back to the inside of the upper half portion. Thereby, the folded-back portion (fold) is located at the lower end portion of the sheet-like member 12 that has been formed into the double-layer structure.

(4) As shown in fig. 14(d), one part of the folded portion of the sheet-like member 12 is cut along a dividing line C indicated by a broken line in the figure.

(5) As shown in fig. 14(e), the outer sheet 13 and the inner sheet 14 of one part of the cut folded part are sewn.

(6) As shown in fig. 14(f), four darts 17 are formed at the opening edge 12aa (upper end) of the sheet-like member 12.

The baby sling 11 of the present embodiment can be formed by the above-described steps (1) to (6).

Next, the procedure of wearing the baby sling 11 by the protector will be described with reference to a wearing method called "cradle style hug" as shown in fig. 1.

First, as shown in fig. 15, taking the shoulder coupling portion 15 as an example, the protector hangs the infant sling 11 obliquely in a state where the protector is coupled to the right shoulder of the protector.

Thus, the protector can easily wear the infant sling 11 by simply hanging it obliquely.

Next, the protector first holds the child with one arm and at the same time separates the outer sheet 13 constituting the sheet-like member 12 in the wrapping portion 16 and the opening edge 12aa of the inner sheet 14 from each other with the other arm.

Thus, the protector can open the opening B (see fig. 2) at the upper end of the holding portion 16, and accommodate the infant in the holding portion 16 through the opening B as shown in fig. 1.

The baby carrier 11 of the present embodiment can produce the following operation and effect when the infant is wrapped in the wrapping portion 16 as described above.

The wrapping portion 16 of the present embodiment has elasticity (elasticity), and the lower end sewn portion 21 is not formed at the lower end portion of the wrapping portion 16. Therefore, as shown in fig. 16, the holding portion 16 can be bent and deformed according to the body size of the infant.

This allows the body part such as the buttocks of the infant to be sufficiently closely attached to the holding portion 16. Accordingly, since the stability of the infant in the holding portion 16 can be ensured and the holding portion 16 can be extended and contracted, the infant does not feel a sense of pressure.

A tuck forming portion 17 is formed at the opening edge 12aa of the opening B. By forming the tuck-forming portion 17, a seam is formed at a portion where a tuck is formed. The seam can limit the expansion and contraction of the opening edge 12 aa.

Thus, since the expansion and contraction of the opening edge 12aa can be restricted by forming the tuck forming portion 17 in the opening edge 12aa, the expansion and contraction of the opening edge 12aa can be restricted so that the opening edge 12aa does not excessively stretch or slacken.

In addition, since the opening edge 12aa is tightened by forming the wrinkle forming portion 17, the length of the opening edge 12aa can be made short. This can keep the size of the opening B small.

Thus, although the holding portion 16 is stretchable, even if the weight of the infant is applied to the opening edge 12aa, the opening B is not excessively expanded, and the infant does not fall through the opening B.

Further, when the infant is taken out of and put into the holding portion 16, the opening B can be opened easily as the protector intends.

Further, as in the baby sling 11 of the present embodiment, by forming the tuck-forming portion 17 between the shoulder connecting portion 15 and the holding portion 16 in the circumferential direction of the sheet-like member 12, it is possible to increase the strength of the portion between the shoulder connecting portion 15 and the holding portion 16, which is particularly likely to cause a load when the baby sling 11 is worn, and to keep the overall shape of the baby sling 11 from becoming irregular.

Therefore, the infant, such as the neck, in the holding portion 16 is not excessively bent, and the abdomen is not excessively pressed.

The baby carrier 11 of the present embodiment is formed in a ring shape by using a single piece of stretchable fabric as the sheet-like member 12, and is formed in a shape to be brought into contact with the front and rear portions of the wearer.

Therefore, the baby carrier 11 can be closely attached to the body of the wearer and can wrap the whole body of the baby without the baby falling off.

Further, the restoring force (elastic force) of the bag portion 16 that stretches in accordance with the body weight of the infant allows the protector to bring the body of the infant into close contact with the body of the infant even without holding the infant actively.

Therefore, the integrity of the protector with the infant can be increased, and the burden of carrying the infant can be suppressed as much as possible.

As described above, the outer sheet 13 and the inner sheet 14 are formed in the bilaterally symmetrical shape, and the outer sheet 13 and the inner sheet 14 are sewn together by the lower end sewing portion 21, so that the manufacturing cost and labor efficiency for manufacturing the baby back cloth 11 can be improved.

Further, a shoulder seam portion 22 is formed in the shoulder joint portion 15. Therefore, when manufacturing the baby sling 11, the sheet-like member 12 can be assembled to form the sheet-like member 12 by forming a portion corresponding to the front body and a portion corresponding to the rear body of the sheet-like member 12 with the same shape as the constituent members of the sheet-like member 12.

Therefore, the manufacturing cost and the labor efficiency can be further improved.

As described above, the lower-end sewn portion 21 is formed at the lower end portion of the sheet-like member 12, and the tuck-forming portion 17 for restricting the expansion and contraction of the opening edge 12aa is formed at the upper end portion of the sheet-like member 12.

As described above, the lower-end sewn portion 21 and the tuck-forming portion 17 are formed between the shoulder-joining portion 15 and the holding portion 16 in the circumferential direction of the sheet-like member 12.

Therefore, the lower-end sewn portion 21 and the tuck-stitch-forming portion 17 can sufficiently reinforce the strength between the shoulder-joining portion 15 and the wrapping portion 16 in the circumferential direction of the sheet-like member 12 from both upper and lower end portions therebetween.

Therefore, when the baby carrier 11 is worn, it is possible to prevent the shoulder connecting portion 15 and the holding portion 16 from being excessively stretched or damaged in the circumferential direction of the sheet-like member 12, which is particularly likely to be loaded and has a small width.

In addition, when the baby carrier 11 is washed with water, the sheet member 12 can be washed with water in a state where the two cloths 13 and 14 are separated from each other, and thus, it is sanitary. In addition, by forming the lower end sewn portion 21 on the sheet member 12, the sheet member 12 can be easily restored to the two-layer structure by the lower end sewn portion 21 after completion of the water washing.

Next, the wearing of the baby carrier viewed from the protector side will be described.

Since the shoulder joint 15 is formed to have a width corresponding to the shoulder of the wearer, the shoulder joint can be brought into contact with the shoulder of the wearer in a surface contact state, and the sheet-like member 12 located at the shoulder joint 15 is also stretchable. Therefore, the protector can comfortably wear the infant sling 11.

As shown by the broken line in fig. 1, a shoulder pad 23 may be attached to the shoulder connecting portion 15. Further, the shoulder pad 23 may be formed to be detachable by using a fixing mechanism such as a surface fastener. Thus, by attaching the shoulder pad 23, the shoulder sewn portion 22 of the shoulder joint 15 can be prevented from partially abutting against the shoulder.

Therefore, the protector does not feel uncomfortable on the shoulder and can wear and use the baby sling 11 more comfortably.

The baby carrier 11 is not limited to the cradle-type clasp, and may be worn by a protector by other wearing methods.

For example, the protector may be worn in a clasping manner called "forward clasping" in which the infant faces forward as shown in fig. 17. Alternatively, the infant may be worn in a so-called "face-to-face standing hug" manner in which the infant is facing the protector, which is not shown.

When the protector wears the conventional baby carrier having the sheet-like holding portion in the above-described wearing method of "forward-type carrying" or "face-to-face standing carrying", the protector is worn in a state in which the protector and the baby are directly facing each other without the sheet-like member 12 interposed therebetween.

Therefore, when the infant is vigorously twisted in the holding portion 16, the infant may be deviated or dropped from the protector.

In contrast, in the baby carrier 11 of the present embodiment, when the protector wears the baby carrier 11 by any one of the above-described "forward-type embracing" and "face-to-face standing embracing", the baby is wrapped in the bag-shaped wrapping portion 16, and therefore the entire outer side of the baby, including the space between the protector and the baby, is present in the sheet member 12 having the wrapping portion 16.

Therefore, even if the infant is vigorously twisted in the holding portion 16, the holding portion 16 itself can be reliably prevented from being displaced and falling, or the infant can be reliably prevented from falling from the holding portion 16.

Further, since the sheet-like member 12 is stretchable, the ground contact portion of the infant in the holding portion 16 stretches in accordance with the weight of the infant, and therefore, if the infant stands in the holding portion 16, as shown in fig. 18, the weight of the infant concentrates on the ground contact portion of the infant in the holding portion 16.

Therefore, the sheet-like member 12 is stretched to increase the depth of the bag-like bag portion 16, so that the infant does not fall off and the safety of the infant can be maintained.

Of course, the baby carrier 11 of the present embodiment may be worn directly by the protector facing the infant without interposing the sheet-like member 12 of the holding portion 16.

Therefore, the procedure of wearing the baby carrier 11 of the present embodiment in the above-described wearing method of the "face-to-face standing hug" in a state where the protector and the baby face each other as described above will be briefly described below.

First, in a state where the infant sling 11 is hung obliquely as shown in fig. 15, the protector holds the infant with the left arm, for example. At the same time, the infant is quickly inserted between the protector and the sheet-like member 12 with the right hand without separating the outer cloth 13 and the inner cloth 14 of the sheet-like member 12 of the holding portion 16, that is, expanding the space between the sheet-like member 12 and the protector in the holding portion 16.

Then, as shown in fig. 19, the protector can support the infant in a state of being completely abutted against the sheet-like member 12 having excellent stretchability as shown in fig. 20 by stretching the wrinkles and the like of the sheet-like member 12 in the holding portion 16 abutted against the back and hip of the infant.

Therefore, as described above, even when the infant is carried in the above-described "face-to-face standing type hugging" in which the infant and the protector are brought into face-to-face contact without interposing the sheet-like member 12, the infant carrier 11 of the present embodiment is worn in a state of fitting to the sheet-like member 12 particularly the buttocks of the infant, and therefore, the infant does not shift and fall even if the infant twists. In addition, since the flexible sheet-like member 12 fits well to the infant, a good wearing state can be obtained.

Further, since the sheet-like member 12 of the baby carrier 11 has a double-layer structure of the outer sheet 13 and the inner sheet 14, the baby can be protected more favorably than the conventional sheet-like member 12 formed of 1 sheet.

Further, since the entire baby sling 11 of the present embodiment is formed of the sheet-like member 12, it is not necessary to provide another member such as a coupling member for coupling the baby sling 11 formed in a band shape into a ring shape, unlike the conventional baby sling 11, and it is not necessary to form the wrapping portion 16 into a folded shape, so that the baby sling 11 can be folded and can be stored in a compact size without increasing its volume even after being folded.

The baby carrier 11 of the present embodiment may be formed of a material having air permeability, such as mesh fabric, or may be formed of a cloth having a fluffy shape, such as the sheet-like member 12, or may be formed of one of the outer cloth 13 and the inner cloth 14.

In the correspondence between the above-described embodiment and the configuration of the present invention, the darts 17a, 17b, and 17c of the present embodiment correspond to the expansion/contraction restricting means for restricting the expansion/contraction of the opening edge 12aa of the present invention, and similarly,

the middle line portion 18 corresponds to a widthwise middle portion of the sheet-like member;

nylon corresponds to a stretch material;

the lower end sewn portion 21 corresponds to an expansion/contraction restricting mechanism for restricting expansion/contraction between the holding portion and the shoulder coupling portion in the circumferential direction of the sheet-like member;

the shoulder sewn portions 22 correspond to sewn portions, but the present invention is not limited to the configuration of the above-described embodiment, and a plurality of embodiments as described above can be obtained.

Industrial applicability

The present invention can be used as a baby carrier for carrying a baby in a baby product.
