Abstract

PROBLEM TO BE SOLVED: To provide a bagged 'futon' allowing a zipper to be smoothly opened and closed, and keeping the zipper free from becoming a problem, regardless of the status of the 'futon'. SOLUTION: Regarding the first and the second two halves 21 and 22 for separating an outer sheet into two parts, a gusset piece 60 is provided only along the periphery of the first half 21, and a zipper 70 is provided at the free end of the gusset piece 60. The zipper 70 has the first zipper member 71 at the free end of the gusset piece 60 and the second zipper member 22 along the periphery of the second half 22. Also, the first zipper member 71 has semi-circular part 71c and 71c near a start point S and an end point E, and a linear part 71 for connecting the parts 71c and 71c to each other. As a result, the constituent of the zipper 70 is not positioned at the back of a 'futon'. Also, the zipper 70 extends along the periphery of an outer sheet to form a part of a 'futon' body 30. Thus, the zipper 70, when opened and closed, is subjected to the resilient force of the 'futon' body 3, thereby being opened and closed relatively smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backed futon which can be stored in the form of a back or function not only as a futon but also as a back, and particularly suitable as a futon for children. Technology.

[0002]

BACKGROUND OF THE INVENTION Conventionally, for example, Japanese Utility Model Laid-Open No. 3-102922.
As disclosed in the publication of the above-mentioned publication, it is already known to store a sheet member such as a leisure sheet in the form of a bag. According to this concept of making the seat back, the seat can be used not only as a back (storage), but also very convenient for carrying.

[0003]

The inventor of the present invention has considered applying such a concept to a futon. In the case of a sheet, its thickness is small, and it is relatively easy to handle when forming a back. On the other hand, the futon has a few cm
And the thickness hinders the backing. For convenient storage, simply fold the futon compactly and place the folded futon inside the handle cover. But that doesn't mean that the futon is backed. To make a bag, it is necessary to make at least a part of the structure of the futon function as a part of the bag.

[0004] Therefore, when converting the futon into a bag, it was premised that a sheet having the futon body disposed on one surface was folded in two, and the other surface of the sheet was used as the outer surface of the bag. At the beginning of the development, the inventor considered that in the form of a bag, gussets were formed on both left and right sides and an upper portion of the bag, and fasteners were arranged in a straight line so as to extend through the center of the gusset. However, in such an arrangement, it is necessary to extend both ends of the fastener to the outer surface of the sheet in order to unfold the folded sheet and use it as a futon. However, it is difficult for the zipper that passes through the center of the gusset to open and close it smoothly, and because a part of it is located on the back of the futon, it gives a feeling of a foreign object to a sleeper, Or it could damage the futon glue (that is, the futon side).

[0005] These difficulties will be more pronounced when a child's futon is turned into a bag. This is because the opening and closing of the zipper is originally difficult for a child, and the child always moves around on a futon. However, considering that the overall size in the form of a bag is suppressed, a child's bag is most suitable as a futon. The present invention has been made in view of the results of the above-described studies, and provides a backed futon that can smoothly open and close the zipper and that does not cause a problem in the form of the futon. The purpose is to: Another object of the present invention is to provide a core block which can be washed as a whole and is suitable as a core of a backed futon.

[0006]

According to the backing futon of the present invention, basically, when the futon is used as a futon, the fastener is not positioned on the back of the futon or the futon main body.
Therefore, regarding the outer sheet constituting the outer side surface of the back, of the first and second halves that bisect the sheet,
A gusset piece is provided only on the periphery of one of the first halves, and a fastener is arranged at a free end of the gusset piece. When the outer sheet is bent back into two parts, the zipper is formed on the left and right side portions of the outer sheet.
From the entire periphery of the half to part of the first periphery. Thus, when the fastener is used as an opener, the components of the fastener are the free end of the gusset along the first half perimeter of the outer sheet and the portion along the second half perimeter of the outer sheet. To position. Thereby, the components of the fastener are no longer located on the back of the futon. Further, since the fastener extends along the peripheral edge of the outer sheet constituting a part of the futon main body, when the fastener is opened and closed, the fastener is effectively supported by the futon main body by receiving the elastic force of the futon main body. Thus, the opening and closing can be performed relatively smoothly. In order to make the opening and closing of the fastener smoother, it is preferable to make the width of the lower part of the gusset piece on the left and right sides of the back wider than the width of the upper part. This is also
It will also increase the capacity or space inside the bag.

[0007] The futon body disposed on the inner surface of the outer sheet,
It consists of a futon kawa and a core block inside.
When holding the shape of the form as a back, and from the point of washing the core block as a whole, as a core block,
It is most preferable to use a material containing a hardened material obtained by hardening synthetic fibers. In addition, the core block in the futon glue is preferably divided into a plurality of pieces so as to be sized so as to enter the washing tub. The futon glue is provided with an opening through which the core block is put in and out, and the opening is preferably made of a fastener. As a preferable core block, there is a structure in which two rectangular parallelepiped blocks are connected to each other at one side, and the rectangular parallelepiped blocks are stacked in two stages, and there is a stopper for drying clothes around the rectangular parallelepiped blocks. be able to. In addition, each rectangular parallelepiped block can be put in a net, and the two rectangular parallelepiped blocks can be connected using the net.
