Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a three-dimensional quilted futon, and more particularly to an improvement in the partition cloth of a three-dimensional quilted futon.

[Prior art and its problems] In recent years, in order to maintain the bulk of the futon, multiple compartments partitioned by tape-like vertical and horizontal partition cloth have been provided in the side fabric, and fillers such as down feathers have been filled and stored in these compartments. A so-called three-dimensional quilted futon has been devised.

In the above-mentioned conventional three-dimensional quilt type futon, the intersections of the vertical and horizontal partition cloths are not sewn to allow the hose for inserting feathers into each compartment to be inserted. Therefore, the feathers moved through this intersection, causing the feathers to be uneven.

Also, some models have small hose insertion holes at the intersections, but in order to fill and store feathers etc. in the compartments, it is necessary to insert the hose etc. by groping across multiple compartments. It took a lot of time to do this, and production efficiency was extremely low.

In addition, cutting the vertical and horizontal partition cloth for each section and sewing the partition cloth to the upper and lower side fabrics one by one in a grid pattern requires a lot of labor and time, and production efficiency is extremely low. It was bad for me.

In view of the above circumstances, this invention provides a partition cloth into which a hose for filling and storing feathers or other stuffing can be easily inserted, and also provides a three-dimensional structure that is extremely easy to attach the partition cloth to the side fabric and has high production efficiency. It provides quilted futons.

[Means for Solving the Problems] In the three-dimensional quilt type futon according to the present invention, the partition cloth is made up of a vertical partition cloth and a horizontal partition cloth each formed in a bag shape and having an insertion hole for inserting a hose. A vertical partition cloth and a horizontal partition cloth are placed on top of one of them, and are fixed to each other at the contact area where they contact each other, and the top and bottom sides of the partition cloth in the thickness direction are and the upper and lower fabrics were fixed to each other at their contact areas. Also,
The vertical or horizontal partition cloth is provided with a notch for inserting a hose at a position facing the compartment to communicate the inside of the vertical or horizontal partition cloth with the compartment, and the vertical or horizontal partition cloth is removed. The positions of the two incisions, which were formed facing the compartments facing each other, were deviated from each other, that is, they were formed at positions that did not coincide with each other.

[Embodiments] Examples of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 1 is a partially cutaway perspective view of a three-dimensional quilt type futon according to this embodiment. Reference numeral 1 in the figure is a partition cloth. The partition cloth 1 is
Consisting of a plurality of vertical partition cloths 2 arranged in parallel at predetermined intervals, and a plurality of horizontal partition cloths 3 intersecting and fixed to each other in a three-dimensional orthogonal manner to the vertical partition cloths 2, a plurality of sections are formed. 4 is provided to form a grid.

As shown in FIG. 2, the vertical partition cloth 2 and the horizontal partition cloth 3 are made by rolling a strip of fabric laminated with a welding agent with the processed side facing up, and welding the long sides together by heating. and joined.
It is formed into a bag shape and has insertion holes 2a and 3a,
In addition, cuts 5 for inserting a hose into each of the sections 4 are provided on the side surfaces of the insertion holes 2a and 3a. Here, the positions of the two notches 5 formed facing the opposing compartments 4 with the vertical partition cloth 2 or the horizontal partition cloth 3 in between are offset from each other, that is, they do not coincide with each other. (see FIGS. 1 and 2).

As shown in FIGS. 2 and 3, the vertical partition cloth 2 and the horizontal partition cloth 3 have a contact area where the horizontal partition cloth 3 is placed on top of the vertical partition cloth 2 and where the two come into contact. It is fixed at. That is, the upper fabric of the vertical partition cloth 2 and the lower fabric of the horizontal partition cloth 3 are welded and fixed to each other by heating, and are in a state where they straddle each other at the intersection 1a. As a result, at the intersections 1a of the vertical and horizontal partition cloths 2 and 3, the insides of each are not welded, so the insertion holes 2a and 3a penetrate from end to end, allowing the hose to be inserted. It's becoming like that.

Furthermore, upper and lower side fabrics 6 and 7 which are laminated with a welding agent and subjected to a down-proofing process are disposed on both upper and lower sides of the partition cloth 1 in the thickness direction, and the upper and lower sides of the partition cloth 1, That is, the upper and lower ends 2b, 2b, 3 of the vertical and horizontal partitioning cloths 2, 3 each having a flat rectangular longitudinal section in a state in which the batting is stored.
The contact portions of b, 3b and the upper and lower fabrics 6, 7 are welded and fixed to each other by pressure and heating.

Further, the peripheral edges 8 of the upper and lower fabrics 6 and 7 are welded and fixed to each other by heat and pressure using an iron or the like, thereby forming a side fabric 9 consisting of the upper and lower fabrics 6 and 7.

Furthermore, inside each section 4 in the side fabric 9, a batting 10 is provided.
It is filled and stored with feathers.

Next, a method for manufacturing the three-dimensional quilt type futon of the above embodiment will be explained.

First, a vertical partition cloth 2 and a horizontal partition cloth 3 are prepared which are made of fabric laminated with a welding agent on one side and are formed into a bag shape with the processed side facing up.

As shown in Figures 4 and 5, approximately
A lower fabric 7 cut to the size of a futon and laminated with a welding agent on the back side is spread out, and a plurality of vertical partition fabrics 2 are arranged in parallel at predetermined intervals on the upper surface (back side) of this lower fabric 7. do. Next, a plurality of horizontal partition cloths 3 are placed on top of the vertical partition cloth 2 and arranged in parallel at predetermined intervals. In this way, the vertical partition cloth 2 and the horizontal partition cloth 3 can be arranged in a grid pattern, and the sections 4 can be formed between them.

Furthermore, on the upper part of the vertical and horizontal partition cloths 2 and 3, the back side of the upper fabric 6 whose back side is laminated with a welding agent faces the partition cloth 1 side, and the lower fabric 7
and their peripheral edges are aligned.

Next, in the above state, from the side fabric side, divider cloth 1
Weld the upper and lower side fabrics 6, 7 and the partitioning fabric 1 by applying pressure and heating using a well-known pressure heating machine (arrow A in Fig. 4) in a band shape along the lattice-like shape and the peripheral edge 8 of the side fabric 9. and stop. Through this process, the upper and lower fabrics 6,
7 and the upper and lower ends 2b, 2 of the vertical and horizontal partition cloths 2, 3
b, 3b, and 3b are welded and fixed. In this case, a portion of the peripheral edge 8 of the side material 9 is formed with a portion that is not fixed, and an insertion opening 9a for inserting a hose is provided.

Next, a hose (not shown) connected to the feather reservoir is inserted through the insertion port 9a, and then the insertion holes 2a and 3a of the vertical or horizontal partition cloths 2 and 3 and the notches 5 are inserted.
A predetermined amount of feathers is sequentially inserted into each compartment 4 and stored therein.

After filling and storing the feathers, open the insertion slot 9.
Seal a.

The three-dimensional quilt type futon of the above embodiment has a partition cloth 1
is formed of vertical and horizontal partitioning cloths 2 and 3, and these vertical and horizontal partitioning cloths 2 and 3 are formed into a bag shape, and the vertical and horizontal partitioning cloths 2 and 3 intersect three-dimensionally at the intersection 1a, and are inserted through each other. The insides of the holes 2a and 3a penetrate from end to end, and the hose can be inserted through the holes. )9
a. The hose can be easily and smoothly inserted through the insertion holes 2a and 3a of the vertical and horizontal partitioning cloths 2 and 3 and the notches 5 without any trouble, making it extremely easy to fill and store feathers, and to improve productivity. Efficiency is greatly improved. In this case, since the insertion holes 2a and 3a pass through each end from end to end, the hose can be inserted from either direction of the vertical and horizontal partition cloths 2 and 3, and the hose will not get stuck at the intersection 1a. It can be inserted easily, making the work easier and more efficient.

Moreover, even if the insertion holes 2a and 3a are formed in the vertical and horizontal partition cloths 2 and 3, the insertion holes 2a and 3a are formed after filling with feathers.
3a is pressed and crushed by the pressure of the filled feathers, and the vertical and horizontal partitioning cloths 2 and 3 are in the same state as normal one-piece cloth.

In addition, the vertical partition cloth 2, the horizontal partition cloth 3, and the upper and lower side fabrics 6 and 7 are made of laminated fabric,
They are welded together at the intersection 1a by pressure and heating using a pressure-heating machine, and the partitioning cloth 1 can also be fixed to the upper and lower fabrics 6, 7 in one step using a pressure-heating machine, without sewing with thread. Since the provided side fabric 9 can be easily manufactured, the labor-intensive manufacturing of the partition cloth and the work of fixing the partition cloth to the upper and lower fabrics can be done extremely easily.

As a result, the above-mentioned filling and storage of feathers is simple and easy, and the manufacturing efficiency of the futon becomes extremely high, and costs can be reduced significantly.

In addition, since the means for attaching the upper and lower fabrics 6 and 7 to the partition cloth 1 is by welding, there is no gap at the joint, and unlike when sewn with thread, the feathers do not blow out from section 4 to section 4. There is no movement and the feathers do not shift.

In addition, the insertion holes 2a and 3a of the vertical and horizontal partition cloths 2 and 3
After being filled with feathers, the feathers are pressed by the pressure of the filled feathers, and since adjacent notches 5 are provided at locations that do not coincide with each other, the feathers do not move and become unbalanced.

In addition, in the above embodiment, the vertical and horizontal partition cloths 2,
In No. 3, the long sides of the strip-shaped fabric were welded together to form a bag shape, but it may be knitted into a bag shape without welding.

Furthermore, the vertical and horizontal intersecting relationship between the vertical and horizontal partition cloths 2 and 3 may be such that either one is vertical or vertical. Note that in this invention, the significance of up and down in side fabrics, etc. is relative.

In addition, the vertical and horizontal partition cloths 2 and 3 and the partition cloth 1
The means for fixing the upper and lower fabrics 6, 7 to each other is not limited to welding by heating or the like, but may also be a fixing means using an adhesive.

Further, the peripheral edges 8 of the upper and lower fabrics 6, 7 may be secured not only by welding or adhesive means, but also by hemming or sewing with thread.

Further, the batting 10 is not limited to feathers, but may also be made of synthetic cotton or cotton.

[Effects of the Invention] As explained above, the three-dimensional quilt type futon according to the present invention is formed in a bag shape and has vertical and horizontal partition cloths having insertion holes that intersect in three dimensions, and the mutual contact portions at the intersections. Since the insertion hole is penetrating, the hose can be easily inserted without getting stuck at the intersection.
It is extremely easy to insert the batting into the feathers, improving manufacturing efficiency.

Further, the present invention provides a structure in which a vertical partition cloth and a horizontal partition cloth are placed on top of one of the other cloths, and are fastened to each other at a contact portion where the two contact each other, and the vertical and horizontal partitions are Since the upper and lower surfaces of the fabric in the thickness direction and the upper and lower fabrics are fixed to each other at their contact portions, the following effects are achieved.

Unlike conventional methods, there is no need to cut at least one of the vertical and horizontal partition fabrics to the width of each section, and then arrange and sew each partition fabric to the upper and lower side fabrics in a grid pattern. . That is, by simply placing one of the vertical and horizontal partitioning cloths formed in the shape of a long bag on top of the other, a partition can be formed between the vertical and horizontal partitioning cloths, and then, By fixing the vertical and horizontal partition fabrics and the upper and lower side fabrics by means such as welding or gluing, each compartment can be closed, so the partition fabric and the side fabrics can be sewn together. A three-dimensional quilt type futon can be obtained without going through the complicated and difficult work of forming sections. This improves the production efficiency of futons,
This has the effect of reducing costs.

In particular, according to the present invention, at the intersection of the vertical and horizontal partition cloths, one is placed on top of the other and the two are fastened together to form a closed compartment. As with the technique, it is possible to prevent the problem of feathers shifting at intersections, and prevent the feathers from becoming uneven.

Furthermore, according to the present invention, a notch for inserting a hose is provided in a position of the vertical partition cloth or horizontal partition cloth facing the compartment, which communicates the inside of the vertical partition cloth or horizontal partition cloth with the compartment, and Since the positions of the two cuts, which were formed facing the sections facing each other with the vertical or horizontal partition cloth in between, were formed at positions offset from each other, that is, positions that did not coincide with each other, It produces the effects shown in ~.

A hose for filling batting (particularly feathers) can be inserted into the compartment through the cut, and the batting can be easily filled.

Moreover, once the filling is filled, the pressure of the filled filling presses the partition cloth and collapses it, so when the user jumps on the futon, pressure is suddenly applied to the compartment. Even if the filling is removed, the possibility of the filling flowing into other compartments or flowing back into the partition cloth can be reduced as much as possible.

Furthermore, as mentioned above, since the positions of the two cuts are offset from each other, even when pressure is applied to one compartment, the batting filled in the compartment is , it becomes almost impossible for the flow to flow back into other adjacent compartments. This is because when pressure is applied to a compartment, the partition cloth collapses, so the batting in the compartment passes through the inside of this partition cloth, and then passes through the notch in the deviated position. This is because it is practically impossible for the robot to move to another section. This makes it possible to almost completely prevent the filling from becoming uneven.
