Alternatively, the chest band 4 and the back pad 2 may be directly connected to each other by using an engaging means such as sewing or a hook without providing the connecting band 6. Further, an adjusting belt 17 sewn to each of the chest pad 4 and the back pad 2 is provided on the outside of the connecting band 6, and the buckle provided on one adjusting belt 17 is provided on the other adjusting belt 17.
By adjusting the insertion length, the distance between the chest pad 4 and the back pad 2 can be adjusted according to the size of the baby.

On the side opposite to the connecting band 6, a chest pad side connecting portion 7 which bulges in an arc shape from the side edge of the chest pad 4 is provided integrally with the chest pad 4, and the back pad 2 is provided. The back support part side connecting part 8 which bulges in an arc shape from the side edge is provided integrally with the back support part 2. An attaching / detaching mechanism 9 is provided on the chest pad side connecting portion 7 and the back pad side connecting portion 8, and by attaching / detaching the attaching / detaching mechanism 9, the side portion of the main body 10 can be attached and detached.

FIG. 19 shows a conventional attaching / detaching mechanism 9, and FIG.
Reference numeral 0 indicates another conventional attaching / detaching mechanism 9. In FIG. 19, the protruding piece locking member 7 is sequentially attached to the chest pad side connecting portion 7 from the top.
1, the first hook 73 and the second hook 73 are attached, and the projection piece locking member 7 of the other back support portion side connecting portion 8 is attached.
The projection piece 81 is attached to the corresponding portion 1. When the projection piece 81 is lowered into the projection piece locking member 71 from above, the projection piece 81 is locked to the bottom of the projection piece locking member 71. The projection piece 81 does not come out of the projection piece locking member 71 unless it returns upward. Thus, the two hooks, the first hook 83 and the second hook 8 located below the projection piece 81 with the projection piece 81 locked to the bottom of the projection piece locking member 71.
3 are fitted to the first hook 73 and the second hook 73 of the chest-pad-side connecting portion 7, respectively, and keep the projection piece 81 from returning upward. However, in the attaching / detaching mechanism 9 as shown in FIG. 19, since the chest pad side connecting portion 7 is made of cloth, it is easily bent, and the protruding piece locking member 71 is bent by the movement of an infant during use. It happened to slide down to the hook 73 side. Then, the engagement between the projection piece locking member 71 and the projection piece 81 is released, and then the lower first hook 7 is released.
It happened that 3 and 83 as well as the second hooks 73 and 83 could easily come off.

FIG. 20 shows another conventional attaching / detaching mechanism 9 in which the drawbacks of FIG. 19 have been improved. In FIG. 20, the chest pad side connecting portion 7 has an engaging elastic piece storage member 72 and a first hook 7 in order from the top.
3, the second hook 73 is attached, and the engaging elastic piece 82 is attached to the part corresponding to the engaging elastic piece storage member 72 of the back support part side connecting portion 8, and the engaging elastic piece is attached from above. When the engaging elastic piece 82 is lowered into the piece accommodating member 72, the engaging elastic piece 82 is attached to the upper part of the engaging elastic piece accommodating member 72.
Abut on and engage with each other and the tip end of the engaging elastic piece 82 is largely curved inward, so that this portion engages with the lower portion of the engaging elastic piece accommodating member 72 and is locked as compared with that of FIG. Be more certain. Not only that, the thickness of the cloth portion 74 of the attachment portion of the engaging elastic piece storage member 72, the first hook 73, and the second hook 73 of the chest pad side connecting portion 7 is made thicker than that of the other cloth portion 75. As shown in FIG.
It is less likely to bend as compared to the No. 9 one. Therefore, the engaging elastic piece 82 is less likely to be disengaged from the engaging elastic piece housing member 72 even if the infant moves a little.

However, although the one in FIG. 20 is more difficult to come off than that in FIG. 19, it is not perfect and sometimes comes off. This is because the thick cloth portion 74 also bends depending on how the force is applied. Figure 6 is intended to solve these drawbacks, there is provided a detaching mechanism 9 without departing in any way trying Abareyo how infants. The attachment / detachment mechanism 9 of FIG. 6 is composed of a first engagement mechanism and a second engagement mechanism, and mainly includes an insertion opening 19 and a locking opening 20 provided on the back side of the back support portion side connecting portion, and these insertion openings. 19 and a fitting projection 21 provided below the locking opening 20, and a locking projection 22 provided on the front side of the chest pad side connecting portion 7 and provided at a position corresponding to the insertion opening 19 and the locking opening 20.

0 and the fitting protrusion 21) are formed, and the other one of the first engaging mechanism and the other of the second engaging mechanism (that is, the locking protrusion 22 and the fitting port 23) are formed on the second synthetic resin support plate 28. Is formed.

Further, a short cylindrical raised portion 25 is formed so as to project from the surface of the support plate 24, and a substantially cylindrical insertion opening 19 is formed on the upper surface of the raised portion 25.
A substantially cylindrical locking port 20 is provided so as to communicate diagonally above. The insertion opening 19 has a diameter larger than that of the bulging portion 30, and the locking opening 2
The diameter 0 is smaller than that of the bulging portion 30. Insertion port 19 and locking port 2
The center line L connecting the respective centers of 0 is formed obliquely with respect to the vertical direction of the main body 10. This makes it difficult for the locking projection 22 to be disengaged from the locking port 20 with respect to the force normally applied directly below. ing. The locking port 20 is located above the insertion port 19 and slightly outside thereof. Then, the insertion opening 19 and the locking opening 2
The communication point with 0 is narrowed slightly by the narrowed portion 26, and further outside the narrowed portion 26, there are two long holes 27, 27.
Are provided so that the narrowed portion 26 has an elastic force. The interval between the narrowed portions 26 is equal to
The shaft portion 29 has a value such that it can overcome the elastic force and pass through the narrowed portion 26 only when a predetermined force is applied. Furthermore, the insertion opening 19, the locking opening 20, and the narrowed portion 2
6. Below the raised portion 25 having the long hole 27 formed on the upper surface,
Short cylindrical fitting protrusion 2 with a slight bulge at the tip
1 is projected. The support plate 24 having the insertion port 19 and the locking port 20 and the fitting protrusion 21 is sewn on the back side of the back support portion side connecting portion 8 along the arc of the outer periphery.

A locking projection 22 and a fitting port 23 provided on the front side of the chest-pad-side connecting portion 7 are also integrally formed on the synthetic resin support plate 28, and the locking projection 22 is formed into the insertion port 19 and the locking port 20. A cylindrical shaft portion 29 is provided at a corresponding position, is fixed to the support plate 28, and a short cylindrical bulging portion 30 is provided at the tip of the shaft portion 29. This bulge 30
It has a diameter such that it is inserted into the insertion port 19 and does not separate from the locking port 20.

The fitting protrusion 2 is located below the locking protrusion 22.
A fitting port 23 is provided at a position corresponding to 1. A short tubular ridge 31 is projected from the support plate 28.
On the upper surface of the raised portion 31, there is formed a fitting opening 23 formed of a circle having a diameter slightly smaller than the circle of the fitting projection 21, and further from this fitting opening 23, four slits 3 are radially formed.
2 is provided, and an elastic member 33 is provided between the slit 32 and the slit 32. Therefore, when the fitting protrusion 21 is put on the fitting port 23 and the fitting protrusion 21 is pushed from above with a slight force, the bulging portion of the fitting protrusion 21 is provided with the four slits 32 provided in the fitting port 23. It is fitted and fixed in the fitting port 23 by the elastic action of. The support plate 28 provided with the locking projections 22 and the fitting openings 23 is sewn on the front side of the chest pad side connecting portion 7 along the arc of the outer circumference. The fitting projection 21 and the fitting opening 23 are attached at the same position in the state where the locking projection 22 is locked in the locking opening 20.

On the front side of the backrest-side connecting portion 8, a bag-like handle 3 is provided along the arc-shaped periphery of the backrest-side connecting portion 8.
By providing 4, the attaching / detaching operation of the connecting portion 8 becomes very easy. FIG. 4 shows a state in which the mother inserts four fingertips into the bag-shaped handle 34 and operates the connecting portion 8. As will be described later, the handle 34 does not necessarily have to be bag-shaped.

Further, as shown in FIG. 5, the attaching / detaching mechanism 9 is located outside the chest pad side connecting portion 7 and the back pad side connecting portion 8.
A safety belt 35 having a buckle is provided outside the. In this safety belt 35, a buckle male die 36 is provided on the tip of the belt sewn on the surface of the chest pad 4, and a buckle female die 37 is provided on the tip of the belt sewn on the back pad 2. By mounting the male die 36 on the female die 37, the safety of the side portion can be further ensured, and at the same time, the distance between the chest pad 4 and the back pad 2 can be adjusted according to the size of the infant. ing. Further, since the safety belt 35 is provided on both the attachment / detachment mechanism 9 side and the connecting belt 6, the distance between the chest support portion 4 and the back support portion 2 can be adjusted to the same right and left.

The male die 36 is provided with two elastic engaging pieces 38, 38 which elastically move in a direction orthogonal to the inserting direction, and the proximal end thereof serves as an adjusting tool for adjusting the length of the safety belt 35. ing. The female die 37 has a hollow box shape and has an insertion opening 39 for the male die 36, and step portions on the inlet side of the insertion opening 39 are engaging portions 40, 40. Further, release members 41, 41 are attached to the outside of the engaging portions 40, 40 so as to be rotatable around the base end of the female die 37.

Therefore, the length of the safety belt 35 is appropriately adjusted by the buckle of the male die 36, and the male die 36 is inserted into the insertion opening 39 of the female die 37. At this time, the elastic engagement pieces 38, 38 are elastically deformed inward by the insertion opening 39. When the elastic engaging pieces 38, 38 pass through the insertion opening 39, the elastic force of the elastic engaging pieces 38, 38 elastically moves outward to engage the engaging portions 40, 40, and the safety belt 35 is attached. When removing the safety belt 35, the release members 41, 41 of the female die 37 are pushed inward from the side to release the engagement between the elastic engagement pieces 38, 38 and the engagement portions 40, 40. As described above, according to the embodiment of the present invention, the conventional D ring shown in FIG. 5A (that is, two D-shaped rings are used to fix one of them together with a belt and the other belt It is possible to make the operation extremely easy, quick, and safe because it does not use the mounting method in which the two rings are passed through above and below.

A pocket 42 is provided on the front surface of the back support 2. Further, the head support 43 can be attached to the upper part of the back support part 2. The head support 43 is made of cloth, has a strip shape, is curved in an arc shape, and is gradually narrowed toward both ends. And
The heads of infants are held by using the hooks provided at both ends of the back rest portion 2 through the insertion portions 44 formed on the inner surface 2a of the back rest portion 2 and stopping the hooks on the upper portion of the chest rest portion 4. The inner surface 43a of the head support 43 has a synthetic fiber of cotton / polyester or the natural fiber (trade name: chitopory).
And sew. Then, the couplings 13 and 13 of the shoulder straps 5 and 5 are provided with buckles having the same structure as the male die 36 and the female die 37 provided on the safety belt 35.

A method of using one of the baby-sitting bands 1 of the present embodiment configured as described above will be described. The back rest part 2, the crotch rest part 3, and the chest rest part 4 of the main body 10 are respectively applied to the body of an infant, and the adjustment belt 17 outside the connecting band 6 is adjusted to an appropriate length. Then, on the other side portion, a finger is put into the handle 34 of the back support portion side connecting portion 8 and the locking projection 2 is inserted into the insertion opening 19.
2 bulge 30 is inserted (see FIG. 7), and then stenosis 2
The bulging portion 30 is pulled diagonally upward to lock the bulging portion 30 against the locking opening 20 against the elastic force of 6. At this time, the small-diameter shaft portion 29 of the locking projection 22 comes to pass through the narrowed portion 26.
Since the interval between the narrowed portions 26 is formed to be slightly smaller than the diameter of the small diameter shaft portion 29, when passing through the narrowed portion 26, the small diameter shaft portion 29 pushes the narrowed portions 26 in a direction to spread each other. An elongated hole 27 is formed on the outer side of the narrowed portion 26 so that the narrowed portion has an elastic force in this case. Therefore, after the small-diameter shaft portion 29 passes through the narrowed portion 26 against this elastic force, the bulging portion 30 is locked in the locking port 20. Since the fitting projection 21 and the fitting opening 23 are completely aligned and correspond to each other in a state where the bulging portion 30 is locked in the locking opening 20, the fitting projection 21 is fitted into the fitting opening 21. The attachment / detachment mechanism 9 is mounted by fitting the elastic member 33 against the elastic force of the elastic member 33 (see FIG. 8). Then, in the bulging portion 30 of the locking projection 22 locked to the locking opening 20 which is the first engaging mechanism, the insertion opening 19 and the locking opening 20 are obliquely positioned, and elastic force The presence of a certain narrowed portion 26 not only makes it difficult to move in the direction of the insertion opening 19, but also the bulging portion 30 of the locking projection 22 due to the fitting of the fitting projection 21 and the fitting opening 23 which are the second engagement mechanism. The movement toward the insertion opening 19 is impossible unless the second engagement mechanism is released, and the embodiment of the present invention allows the infant to be transported safely. Moreover, the safety belt 35 is further used on the outside thereof, and the male die 36 of the safety belt 35 is put into the female die 37 at this time (see FIG. 5).

[0028] By using this baby litter 1, an infant can be carried on the chest side (so-called "ducking") or can be carried on the back side (so-called "piggyback"). In the case of "Dako", place the back rest part 2, crotch rest part 3 and chest rest part 4 of the baby-sitting band 1 on the chest side of the mother and hang the two shoulder belts 5 and 5 on both shoulders of the mother. I wear the baby litter 1, but since the slope is down from the neck to the shoulders, the two shoulder belts 5 and 5 hung on both shoulders are easy to slip off from the shoulder while in use. If the mother raises her shoulders to prevent it from slipping off, she will get stiff shoulders. In order to prevent these, when the buckles provided on the shoulder straps 5 and 5 are attached, the shoulder straps 5 and 5 are always maintained at a predetermined distance from each other, so that the shoulder straps 5 and 5 are no longer present.
There is no need to worry about slipping off your shoulder.

In the case of "onbu", the back rest portion 2, the crotch rest portion 3, the chest rest portion 4 and the like of the baby carrier 1 are placed on the back side of the mother, and the two shoulder belts 5 and 5 are respectively placed on the mother. The baby carrier 1 is worn on both shoulders, but in this case, the buckles provided on the shoulder belts 5 and 5 are not worn on the chest side as in the case of "Dako". This is because the mother's chest is tightly clamped and cramped. Instead, the waist belt 15 is rotated around the waist portion, and the buckles 16 provided at the tip of the waist belt 15 are mutually locked.
I wear it and wear the lullaby 1 firmly. As a result, even if the baby slightly bends his or her upper body, or if the mother takes a slight forward bend or bends,
The baby-sitter 1 does not roll, so that an infant does not fall out.

The head support 43 is used to hold the head of the baby when the head of the baby is not yet seated. Needless to say, the head support 43 can be removed when it is not necessary. Further, by providing the handle 34, the breast rest portion side connecting portion 7 and the back rest portion side connecting portion 8 can be easily attached and detached, and a simple babysitter 1 can be provided.

Further, the insertion opening 19 and the locking opening 20 and the fitting projection 21 provided on the back side of the back support portion side connecting portion 8 are integrally formed with a single support plate 24 made of synthetic resin, and If the locking projection 22 and the fitting port 23 are integrally molded with the single support plate 28 made of synthetic resin, not only the molding becomes easy, but also attachment to the chest support part side connection part 7 and the back support part side connection part 8 is possible. Also, since it becomes easy to sew (widely or linearly sewn) in a wide range, even if a slight breakage occurs, unlike the conventional hooks (dotted sewn), it does not fall off.

In the above embodiment, the attaching / detaching mechanism 9 is
An insertion opening 19 and a locking opening 20 are provided on the back side of the back support portion-side connecting portion 8.
Although the and are provided, it may be on the side of the chest pad side connecting portion 7,

As described above, according to the present invention, since the side portions of the baby-sitting band are mounted by the double engaging means, the baby-shelving band is hard to come off and is safe. And, as in the embodiment, if the insertion opening and the locking opening are positioned obliquely, there is an effect that the bulging portion locked in the locking opening is unlikely to come off. Further, the insertion port and the locking port and the fitting protrusion provided on the back side of the backrest side connecting part are integrally formed with a single support plate made of synthetic resin, and the locking protrusion and the fitting port are also integrated. If it is integrally formed with a single support plate made of synthetic resin, not only the molding becomes easy, but also attachment to the chest pad side connecting portion and the back pad side connecting portion becomes easy. Also, by providing a handle,
(EN) Provided is a simple baby-sitting band that allows easy attachment / detachment of the chest-rest-side connecting portion and the back-rest-side connecting portion. Further, by providing the safety belt, even if there is an accident such that the attachment / detachment mechanism comes off, the safety of the side portion becomes more reliable.
