Description

      The present invention relates to a back-and-use baby sheet that can change a sheet-like article into a bag-like article in accordance with various usage purposes.

      In the past, when an infant was taken out, there were cases where the infant was laid down, such as changing diapers, and it was necessary to carry the sheets and necessary items in a carrying bag. In addition, in the case of one person, after the treatment, it was inevitably an inconvenient and unsafe act such as a one-handed operation to hold an infant. Therefore, in order to clean up and carry these loads as efficiently as possible, there has been proposed a bag that also serves as a back as shown in Patent Documents 1 to 6. However, in Patent Documents 1 to 4, although the convenience as a sheet is high, the weight and bulk are large and it is inconvenient to carry. In addition, even those that can be folded as in Patent Document 5 or 6 cannot be easily formed into a back shape with one hand, and since a bottom plate is used as in Patent Document 6, it is necessary to deal with weight and storage, Due to the circular shape, there was room for improvement when it was used as a baby seat, for example, wasted parts.

    The present invention relates to a baby seat which can be used as a back so that the baby seat can be easily transformed into a back with one hand while holding a baby or carrying a heavy load, and the burden on carrying is reduced. Is to provide.

    This invention is provided with a plurality of holes for passing a string at a position symmetrical to the center line in the periphery of the sheet on a sheet of flexible material such as a rounded rectangular flat cloth or synthetic resin, This is a baby seat that can be used as a bag, which is formed by passing a string-like body through the holes alternately and then closing it in a loop. At this time, the hole provided in the periphery of the seat is at least a pair of left and right holes in the periphery of the seat that becomes the bottom when the back shape is formed, and a string-like body outlet (hereinafter referred to as a "pull-out mouth"). And a pair of holes provided at both ends in the longitudinal direction. In addition, a pair of holes used as a pulling mouth become a position which forms a side wall substantially when it is set as a back | bag form.

In a state where the back-use baby sheet is spread in a flat shape, when the string-like body part passing through the pair of pulling mouths at both ends in the longitudinal direction is picked up with one hand and pulled up at a stroke, the rounded round part is near the mouth part of the back Forming a side surface and the end portion of the sheet rectangular portion in the longitudinal direction forms a back side wall, and at the same time forms a bottom of the back that is close to the width of the pull opening and the thickness of the back side wall, and between the raised pull opening The bag is formed so that the string-like body functions as a handle. The back shape can be formed more neatly and quickly by folding the sheet inward with respect to the pulling mouth, folding it in the longitudinal direction so as to be symmetrical, and pulling up the string-like body straddling the pulling mouth with one hand at a stretch. . In this way, the sheet of the present invention makes it possible to form a back with the weight of the sheet and the pulling force, although it is light, without using materials for maintaining the shape and weight of the bottom plate, etc. Can be achieved.

    In particular, in the baby seat for back use, the position of the hole to be passed in order to form a part of the string-like body as a handle has a width in the sheet minor axis direction from the center on the periphery of both ends in the longitudinal direction of the sheet. In the case of the vicinity of the position at a distance of 1/4, the balance between the height of the side wall and the surface to the opening when the back is formed can be more preferable.

    Further, in the baby bag for back use, the position of the hole through which the string-like body passes includes the vicinity of the arc start point, the arc midpoint, and the arc end point position around the rounded corners of the sheet. When pulling up the part of the string that passes through, the force is first generated against the frictional resistance because the string can be bent due to the presence of the hole at the middle point and end point of the arc, Since the string-like body acts to be a straight line as the base point, the sheet near the rounded corner starts to rise from the pull mouth, and at the same time, the bending near the end point of the arc is reduced, so the base point where the force is applied next is It moves to the hole near the bottom, and this time, the side wall is formed so as to form a ridge between the bent portion and the bottom near the end point of the arc. The rounded corner portion forms a side surface in the vicinity of the back mouth portion. Therefore, when opening and closing the back mouth, it can be performed with the same feeling as a general back.

  More preferably, if the string-shaped body formed in a loop shape is fixed at one point by sewing or the like in the vicinity of the intersection with the short axis passing through the center of the sheet, and the structure is such that the string-shaped body does not move. Since the force can be applied so as to uniformly form the back from the base point, the back can be more easily shaped with one hand.

    Further, if a handle is provided between the pull-out openings of the string-like body or a fastening member such as a hook-and-loop fastener or a hook is attached to the inner surface of the sheet main body between the pull-out openings corresponding to the openings, the function as a back can be further enhanced. .

With this invention, it is possible to form a bag with one hand while holding an infant or holding a heavy load by simply lifting the handle part up after use as a baby seat. In addition, it can be made a lightweight baby bag that can be carried around. In addition, it can be used for textile materials that are no longer necessary for the material of the sheet. For example, it can be washed and used cleanly, and it can be recycled for environmentally friendly and inexpensive production. is there.

Developed baby seat for back use. The figure which showed the state of use of a back combined baby seat. The figure when formed as a back. A photograph when formed as a bag based on Example 1 and Comparative Example 2.

When used as a sheet 1 as shown in FIG. 1, the baby bag for back use has a rounded rectangular planar shape, and has flexibility such as cloth, quilt or synthetic resin, and is soft. Since it is made of a material having a thickness as required, it can be used as a rug or a cushion. Around the sheet 1, natural materials such as Edo string or soft synthetic resin string 3 are alternately passed through the holes 2 arranged around the sheet and formed into a loop or tied using a binding tool. One loop is formed, and the string-like body 2 in the portion between the longitudinal ends of the sheet 1 in the longitudinal direction is lifted so as to be pulled up lightly at a stretch to form a back. . The bag formed in this way can be used as a handbag or a shoulder bag because the string-like body pulled up from the pull mouth becomes a handle or a shoulder plate. At this time, as shown in the drawing, a movable protective member may be attached to the handle portion 5 so as to be easily held, and when an accessory such as a pocket is provided on the back surface or the inner surface, the use range is further widened. can do. In particular, attaching a flexible accessory having the same shape as that of the back side to both sides of the back so that the weight and the outer shape can be maintained will improve the beauty and convenience of the back. In addition, if the eyelet etc. are utilized for the hole to provide, the friction of a string will become fixed and it will become easy to make a back shape smoothly.

The arrangement of the holes in the sheet is symmetric with respect to the center line on the periphery of the sheet, and preferably at equal intervals, the side walls of the back and the overall shape can be easily balanced. In particular, the hole of the pulling mouth is located near the position at a distance of 1/4 of the width in the sheet minor axis direction from the center on both ends in the longitudinal direction, and the position of the hole is near the start point of the arc of the rounded corner. Corresponding to the position, the next hole is provided at the midpoint of the rounded arc, the next hole is provided at a position near the end point of the arc, and a string formed in a loop in these holes. It is easy to obtain a well-balanced back shape by providing the fixing points 6 that are alternately passed through, and stitched at one point in the vicinity of both ends of the center width in the longitudinal direction of the sheet. It can also be made very easy.

Also, if the distance between the pull holes at both ends in the longitudinal direction is changed to make the opening the desired size, or the length of the string forming the loop can be adjusted with a knot, etc., it is matched to the body shape The handle length can be adjusted to meet a wide range of needs. And the function as a back | bag can be improved more by attaching the fastening members 4, such as a hook_and_loop | surface fastener and a hook, to an inner surface.

In addition, this invention is not limited to the above content.

    The sheet 1 shown in FIG. 1 is obtained by drilling ten approximately 10 mm holes 2 around a rounded rectangular quilt material having a longitudinal direction of 600 mm, a width of 450 mm, and a weight of 400 g. At this time, the holes 2a and 2a ', 2j and 2j' serving as the pulling mouths are located in the vicinity of the arc starting point of the rounded corner at a position about 1/4 of the width from the center in the longitudinal direction. The center points 2b and 2b ', 2i and 2i', and the arcuate end points 2c and 2c ', 2h and 2h' are positioned. Through these holes, cotton Edo string 3 having a width of 10 mm and a thickness of 5 mm was alternately passed to form a knot loop near the center of 2a. Then, the string was fixed to the quilt sheet near the center in the longitudinal direction by sewing. A hook-and-loop fastener 4 was attached to the sheet between the pulling holes inside the sheet, and a movable protective cover 7 was attached to the handle 5.

The back-use baby sheet thus produced could be used as a shoulder bag (FIG. 2) by gently pulling up the handle with one hand to form a back as shown in FIG. In addition, if the sheet is folded inward with reference to the pull mouth and then folded in the longitudinal direction so as to be symmetrical, and the string-like body of the part of the handle 5 is pulled up with one hand at a stretch, the back can be formed more neatly and quickly. (Fig. 4 (a)).

In the sheet of Example 1, the holes 2a and 2a ′, 2j and 2j ′ of the pulling mouth are located at a distance of about 7/16 or about 9/16 of the width from the center in the longitudinal direction. As in Example 1, an Edo string was passed through to make a back-use baby seat, and when the operation was made to form on the back, the boundary between the heel part of the back side wall and the opening / closing port surface part, and the overall shape was slightly distorted The function was obtained without problems.

Comparative Example 1

Fabricate and handle in the same manner as in Example 1 except that 16 circular holes with a diameter of 450 mm and a weight of 350 g were drilled with 16 holes of about 10 mm, and Edo strings were passed through the holes. Although it has a back shape, it requires a lot of lifting operation compared to the case of a rounded rectangle, and the back opening / closing opening is close to the purse and it is difficult to open and close with one action.

Comparative Example 2

In the sheet of Example 1, the holes 2a and 2a ′, 2j and 2j ′ of the pulling mouth are located at a distance of about 2/16 or about 5/16 of the width from the center in the longitudinal direction. As in Example 1, an Edo string was passed through to make a baby seat that was used as a bag, and when it was formed on the bag, the border between the heel and mouth of the bag was unclear, and the shape became quite distorted, making it difficult to use as a bag. (FIGS. 4B and 4C).
