Description

  The present invention relates to an improvement of a futon which is divided into a plurality of filling cavities by a town tape sewn in a lattice shape in the space formed by the outer material and the lining, and filled with padding such as feathers in each filling vacancy. .

  In a three-dimensional quilt futon filled with feathers in the side fabric, the space in the side fabric is partitioned in advance in a grid pattern with vertical and horizontal town tapes to prevent unevenness due to movement of the feathers in the side fabric. And the structure which prevented the movement of the feather between divisions by filling a suitable quantity of feathers in each division is employ | adopted.

  On the other hand, the filling work of feathers was provided on the side fabric after arranging the vertical and horizontal town tapes in a lattice pattern between the outer material and the lining material, and sewing the upper and lower edges of each machi tape to the outer material and the lining material, respectively. The filling nozzle inserted from the filling port is inserted into each compartment through an insertion opening (filling path = non-sewn portion) provided at the intersection of the town tape.

  By the way, the nozzle insertion opening provided at the intersection of the town tape cannot be closed by stitching or the like after filling with feathers, and is therefore sold and used without being stitched. For this reason, when pressure is applied from the outer surface of the side fabric during the use of the futon, an air flow is generated between the compartments to open the opening, and the feathers move to the other compartment side, causing variations in the amount of feathers in each compartment. Cause.

Various proposals have been made to solve such problems.
In Patent Document 1 (Japanese Utility Model Laid-Open No. 61-151569) and Patent Document 2 (Japanese Patent Laid-Open Publication No. 60-234608), the edge of one of the town tapes is bent in an L shape and the edges are crossed. A configuration is disclosed in which the outer fabric and the lining fabric are stitched together while being in contact with other town tapes.
However, in Patent Document 1, only the upper and lower ends corresponding to the apex of the bent portion of the machi tape are merely stitched locally to the outer surface and the lining, and most of the edges bent in an L shape are not stitched. Since it is in a state, it is merely an annular nozzle insertion opening with no depth. In such a configuration, when the internal pressure of the section is increased by the external pressure, the feathers in one section are easily moved to another adjacent section through the nozzle insertion opening having no depth.

In Patent Document 2, the upper and lower ends of the bent gusseted cloth tape are in contact with the side of the outer gusseted cloth tape as a non-sewn extension part, but the non-stitched extension part is not stitched to the outer fabric and lining. , It is presumed that the movement of feathers between compartments is facilitated through the non-suture extension.
That is, the feathers move on the air flow generated by the change in air pressure. At that time, if the air resistance of the feather filling path at the intersection of the town tapes is small, the movement of the feathers between the sections becomes easy. In patent documents 1 and 2, since the device which enlarges the air resistance in the non-sewn part (feather filling path) and the non-sewn extension part is not made, the configuration is such that the feathers easily pass along with the air.

It is a top view which shows the assembled state. It is a perspective view which shows the characteristic structure of the nozzle for feather filling which concerns on this invention.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a partial cross-sectional plan view of a futon adopting the structure of a feather filling portion according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the configuration of the main part thereof.
In the present specification, the thickness direction of the futon (the direction orthogonal to the outer material and the lining material) is referred to as the vertical direction.

  The duvet 1 is composed of a side fabric 2 having an outer fabric 3 and a lining 4, and a plurality of vertical and horizontal fillings inside the side fabric by sewing the upper and lower edges to the outer fabric and the lining respectively. A strip-shaped vertical town tape 10 and a lateral town tape 20 that are partitioned into a space (filling space) S are provided. The vertical town tape 10 and the horizontal town tape 20 are made of a mesh-like material having air permeability and small pores that do not allow feathers to pass through. The intersecting part (contact part) of both town tapes. At least a part of C is in a non-sewn state, so that a filling path (nozzle insertion path, non-sewn portion, opening) 30 having a size that allows insertion of a feather filling nozzle is formed. The adjacent filling cavities S are in communication with each other via the filling path 30.

  The filling path 30 is a tunnel-like space for introducing a nozzle formed at the intersection C of the vertical town tape 10 and the horizontal town tape 20 (bending piece 22). It is formed by sewing on the side fabric 2 or the like. The filling space 30 has an opening amount that allows insertion of a nozzle for filling feathers, and expands when the nozzle is inserted to allow insertion of the nozzle, but closes when the nozzle is not inserted. Returns to its original shape.

  The upper and lower edges of one of the town tapes, in this example, the vertical town tape 10, are sewn (sewn) to the outer and lining, and the other town tape and the horizontal town tape 20 are upper and lower edges of the vertical town tape 10. You may make it sew on the place near. In this specification, stitching with the stitches that are fine enough to prevent feathers from passing through the upper and lower edges of the town tape and the lining or the other town tape (pitch) is referred to as “stitching with a short stitch”. Called.

In this example, the vertical town tape 10 is a long body extending over the entire length in the vertical direction of the side fabric 2, and the horizontal town tape 20 is a short body having a size corresponding to the distance between adjacent vertical town tapes 10. However, the reverse may be possible. That is, the horizontal town tape 20 may be a long body extending over the entire lateral length of the side fabric 2, and the vertical town tape 10 may be a short body having a size corresponding to the distance between the adjacent horizontal town tapes 20. .
One of the vertical or horizontal town tapes that form one filling space S, in this example, the horizontal town tape 20 has a distance between adjacent vertical town tapes 10 (the length of one side of the filling space S). The tape body 21 having an appropriate dimension, and bent pieces 22 and 23 that are connected to at least one end edge (in this example, both end edges) of the tape body and are shorter than the length of the tape body. Yes. In short, the horizontal gusset tape is obtained by bending both ends of a single tape having a predetermined length to form a bent piece.
Further, in the contact portion C between each of the bent pieces 22 and 23 of the horizontal town tape 20 and the vertical town tape 10 or the side fabric side surface, the entire length or part of the upper and lower edges of the bent piece is the outer and lining. (Alternatively, it is stitched with a vertical gusset tape) (a stitch is stitched with a short stitch), and a filling path 30 for inserting a filling nozzle is formed along a boundary side B between the tape main body 21 and each bent piece 22, 23. . The filling path 30 of the present invention is an openable / closable space extending in a tunnel shape from the boundary side B toward the bent piece.

  In the present invention, the upper and lower edges 22a, 23a of the bent pieces 22, 23 are sewn with a short stitch to the outer surface and the lining (or vertical town tape) over a predetermined length L1, so that the filling nozzle can be inserted. The filling path 30 has a tunnel shape having a length L1. By making the filling path 30 into a tunnel shape, the workability of inserting the filling nozzle from the nozzle insertion directions D1, D2, and D3 is not deteriorated, while the nozzle insertion directions D1, D2, and D3, and the bent piece 22, It is possible to increase the resistance when air and feathers enter the filling path from the direction D4 in which 23 is located, thereby preventing entry and progression. Further, the value of the nozzle insertion direction length L1 can generate a large resistance when air and feathers enter the tunnel-shaped filling path 30 from each direction D1, D2, D3, and D4. Should be selected. This is because feathers cannot move alone, but usually move with airflow.

In addition, by configuring each town tape with a fabric having good air permeability such as a mesh, even if feathers enter and pass through the filling path 30 with air, the air leads from the side of the town tape to the outside of the filling path. Since it is discharged, the feather itself is prevented from entering and passing by a large resistance in the filling path. That is, the filling path 30 is a space (gap) formed between a part of the side surface of the vertical town tape and the edge (bending piece) of the horizontal town tape, but the air that has entered the filling path is vented. Because it is discharged to the outside of the filling path from the inner side surface of the town tape with the property, the filling path (two town tape side surfaces) does not expand due to the air flow, and both the town tapes are in an approaching and intimate state. Can be maintained. For this reason, the entrance and passage of feathers are efficiently prevented by the frictional resistance generated by both town tapes.
Specifically, for example, in one embodiment of the contact portion C of the vertical and horizontal town tape in the present invention, the stitching length of the upper and lower edges of the bent pieces 22 and 23 in the contact portion C is L1, and filling for inserting a filling nozzle is performed. When the vertical length of the path 30 is L2, L1 ≧ L2.

  Since the tunnel-shaped filling path 30 is formed by setting the stitching length L1 of the upper and lower edges in this way, the filling nozzle is inserted from the filling space S1 side (directions D1, D2, D3) where no bent piece exists. On the other hand, it is possible to generate a large resistance force against the movement of feathers from one of the filling cavities S1 and S2 on both the left and right sides of the contact portion C. That is, when the feather enters the tunnel-like filling path 30 from the filling space S2 side where the bent piece is present and tries to enter another adjacent filling space S1, of course, in the opposite direction. (In the case of entering from directions D1, D2, and D3), only the air is preceded and exhausted from the side surface of the tape to the outside, so the filling space cannot be expanded (the space for passing feathers becomes narrow). ), The inner wall surface of the tunnel-shaped filling path 30 can generate a large resistance and prevent the movement of feathers.

Thus, by making the stitching lengths L1 and L1 of the upper and lower edges of the bent pieces 22 and 23 in the contact portion C at least equal to the vertical length L2 of the filling path 30 for inserting the filling nozzle, It is possible to prevent the feathers from moving in two directions between adjacent filling cavities as the air moves through the filling path. That is, when an external force of a predetermined level or more is applied to one of the filling cavities and the internal pressure is increased, even if the feathers in the filling vacancy enter the filling path 30 together with the air (bidirectional movement), the air is quickly exhausted. As a result, the filling space is closed, and the ingress and progress of the feathers are prevented by the frictional resistance of the filling path where the passage space is narrowed.
In particular, when the internal pressure in the filling space where the bent pieces 22 and 23 are located increases to a predetermined value or more, the increased internal pressure acts to press the bent pieces and close the filling path. For this reason, it becomes easier to prevent the movement of feathers from the filling space where the bent piece is located to the adjacent filling space.

FIG. 3 is a perspective view of the main part showing the configuration of the abutment portion according to another embodiment, and the stitching length L1 of the upper and lower edges of the bent pieces 22 and 23 in the abutment portion C is shown as a filling path for filling nozzles. While the length is at least equivalent to the vertical length L2 of 30, the upper and lower ends of the extra length portions 22A and 23A of the bent pieces 22 and 23 are not sewn to the outer fabric and the lining.
Thus, it is not necessary for the bent pieces 22 and 23 to be stitched at the upper and lower ends with a short stitch over the entire length, and it is only necessary that the tunnel-shaped filling path 30 can be formed by being partially stitched.

  Next, the bent pieces 22 and 23 connected to the respective edges of the tape body 21 are brought into contact with the other town tape or the like while being bent at about 90 degrees, and at least a part of the upper and lower edges is sewn. Therefore, it is easy to insert the filling nozzle from the directions D1 to D3 (filling space S1) shown in FIG. 2 and the like, but the nozzle is inserted from the side D4 (filling space S2) where the bent piece is located. It is difficult. Therefore, if each town tape is stitched to the outer fabric or lining and then the periphery of the lining or outer fabric is sewn, it cannot be visually confirmed in which filling space the bent piece exists, and filling by the nozzle It becomes impossible to determine the direction.

On the other hand, in another embodiment of the present invention, as shown in FIG. 1 and FIG. 5, one of the vertical and horizontal town tapes forming one filling space (in this example, the horizontal town tape 20). Is composed of a tape main body 21 and bent pieces 22 and 23 that are connected to both end edges of the tape main body and bent in opposite directions, respectively, so that a filling space where the bent pieces are located, that is, a nozzle Even if the filling direction cannot be determined, filling using the filling path 30 of any of the bent pieces is possible.
That is, FIG. 4 shows a configuration example in which the two bent pieces 24 and 25 of the horizontal gusset tape 20 are bent in the same direction with respect to the tape body 21, and the two bent pieces 24 and 25 have the same filling space. Since it is located in S, the direction in which the nozzle can be inserted when filling the feathers from the filling port 2A provided in the side fabric 2 to each filling space S is one of D5 in the filling path 30 provided in each bent piece. Only direction (direction D4 is not possible). Accordingly, it is impossible to visually confirm the correct nozzle insertion direction after stitching the outer material and the lining material, and the workability is significantly reduced, such as the necessity to confirm the nozzle insertion direction by trial and error.

On the other hand, in the structure of the contact portion C in the futon according to the present invention shown in FIG. 5, the bent pieces 22 and 23 located at both ends of the horizontal gusset tape 20 defining all the filling spaces S are connected to each other. The two bent pieces 22 and 23 which are bent in the opposite direction, in other words, constituting one horizontal town tape, extend into different filling cavities adjacent to each other. For this reason, the direction in which all the filling spaces S can be filled with nozzles can be set to the two forward and reverse directions D5 and D6, and nozzles can be inserted into all filling paths even if the filling direction cannot be confirmed visually. It becomes.
Thus, even if the proper filling direction cannot be determined from the appearance of the futon, the filling operation by the nozzle can be facilitated by enabling the filling from both opposite directions (D5, D6). .

Next, FIG. 6 shows a configuration example of a filling path in a futon according to another embodiment of the present invention, (a) and (b) are perspective views showing the assembly procedure of each town tape, (c ) Is a plan view showing a state in which each town tape is assembled.
In the present embodiment, one town tape, in this example, a plurality of longitudinal town tapes 10 arranged in parallel is extended over the entire length in the longitudinal direction of the side fabric 2, while a short length is provided between the longitudinal town tapes. In the futon having a configuration in which the horizontal town tape 20 is interposed, a non-sewn portion 35 is defined between the side surface of the vertical town tape and the end edge 21A of the horizontal town tape (tape main body 21). Further, a filling path forming piece 40 as a separate member is inserted into the non-sewn portion 35 from above and attached to sew the important points, thereby opening and closing the tunnel shape corresponding to the filling path 30 in each of the above embodiments. A space or gap is formed.

The filling path forming piece 40 is composed of a strip-like piece of the same material as each town tape and having a predetermined length, and is composed of a main piece 41 forming a tunnel-like filling path and an end piece 42 arranged at one end of the main piece 41. Has been. When the filling path forming piece 40 is inserted into the non-sewn portion 35 from above, the outer surface of the main piece 41 comes into surface contact with the corresponding side surface of the vertical tape 10 and the inner surface of the end piece 42 corresponds. After positioning so as to be in surface contact with the outer side surface of the horizontal town tape 20, the upper edge and the lower edge of each of the main piece and the end piece are stitched to the other town tapes 10 and 20, respectively. Since most of the end edge 21A of the horizontal town tape is not stitched, a tunnel-like filling path 30 is formed between the vertical town tape and the book piece 41 with the end edge 21A as one entrance.
The filling path forming piece 40 has a portion corresponding to the bent pieces 22 and 23 in the embodiment described above separated from the tape body 21.

Depending on the model of the sewing machine used when sewing the town tapes 10 and 20 on the outer material and the lining material, the side of the vertical town tape as shown in the embodiment of FIG. Thus, it may be difficult to carry out the operation of sewing the bent pieces 22 and 23 of the horizontal gusset tape while forming the tunnel-shaped filling path 30. On the other hand, if the horizontal wrap tape and the filling path forming piece 40 are provided as separate members as in the embodiment of FIG. 6, both gussets are formed on the lining 4 by the sewing machine of the above model as shown in FIG. 6 (a). After the tapes 10 and 20 are crossed and sewed, the work of setting and filling the filling path forming piece 40 (work of FIG. 6B) is efficient using a different type of sewing machine or by manual work. It becomes possible to carry out automatically.
FIG. 6 illustrates a configuration in which the filling path is formed by stitching one end in the longitudinal direction of the horizontal town tape to the side surface of the vertical town tape via the filling path forming piece 40, but the other end of the horizontal town tape is illustrated. Is the same.

Next, FIG. 7 is a perspective view showing a device for a feather filling nozzle. The feather filling nozzle is a means for pneumatically sending feathers together with pressure air, and feathers containing feathers using air pressure from a pump. The feather supplied from the tank is ejected from the tip of the feather filling nozzle.
The feather filling nozzle 50 according to the present invention has a tongue-like protrusion by projecting one wall portion of the nozzle port 52 of the cylindrical portion 51 having an elliptical or oval opening cross-sectional shape in the distal direction in a tongue shape. A piece 53 is formed. By projecting the tongue-like protrusion 53 at the tip of the nozzle, the tongue-like protrusion 53, which is a thin plate-like body, can be inserted in advance when the nozzle is inserted into the filling path 30. That is, when the tongue-like protrusion 53 does not exist, workability is not good because it is necessary to push the tip of the cylindrical portion 51 having the nozzle port 52 directly into the filling path 30. When provided, the thin tongue-like protruding piece can be pushed into the non-direction portion by preceding the tip portion of the cylindrical portion to open the nozzle portion 52 at the tip of the cylindrical portion. Becomes easy.
If a nozzle having such a tongue-like projecting piece is used, the insertion from the direction D4 in FIGS. 2 and 3 where the conventional nozzle insertion is impossible is also possible.

<Summary of composition, operation, and effect of the present invention>
The futon according to the first aspect of the present invention includes a side fabric 2 having an outer fabric 3 and a lining 4, and a plurality of vertical and horizontal interiors of the side fabric by being assembled in a lattice shape and stitching the upper and lower ends with short stitches, respectively. The vertical town tape 10 and the horizontal town tape 20 (with air permeability) that are divided into the filling voids are provided, and a filling path 30 for inserting a filling nozzle is provided at a contact portion between the vertical town tape and the horizontal town tape. As a result, the adjacent filling cavities are in communication with each other, and one of the vertical or horizontal skirt tapes forming one filling vacancy has a length corresponding to one side of the filling vacancy.

  When the end of the other town tape is stitched to the side surface of one town tape, the other tape edge is bent in an L shape and stitched. Since it is short, the filling path formed between the bent piece at the edge of the other town tape and the side surface of the one town tape is in a low resistance state in which fillings such as feathers can easily enter, pass through, and move. On the other hand, in the present invention, the stitching range is lengthened so that the filling route becomes a tunnel shape (tubular shape, sleeve shape, tubular shape), so the tunnel-like filling route generates a large resistance force, and feathers and the like enter with air. It will not pass or move.

In the futon according to the second aspect of the present invention, one of the longitudinal or lateral gusset tapes forming one filling space S has the tape body 21 and both end edges of the tape body bent in opposite directions.

By forming all the filling cavities with the town tape having such a structure, the filling nozzles are inserted into the side fabrics from two adjacent forward and reverse directions in filling work such as feathers to all the filling cavities. It is possible to insert the nozzle into the side fabric from either the forward or reverse direction without carrying out the troublesome task of marking the direction of filling on the outer surface of the side fabric. It becomes possible to carry out filling to the smooth.

In the futon according to the third aspect of the present invention, the stitch length L1 of the upper and lower edges of the bent piece at the contact portion is a length corresponding to at least L2 when the length of the filling path for inserting the filling nozzle is L2. It is characterized by being set to this.
The stitching length L1 of the upper and lower edges of the bent piece at the abutting portion is arbitrary, but in relation to the length L2 of the filling path for inserting the filling nozzle, by setting L1 ≧ L2, feathers or the like to enter It is possible to increase the frictional resistance against the movement of the filling space such as feathers.

A futon according to a fourth aspect of the present invention is a vertical fabric tape that assembles a side fabric and a plurality of vertical and horizontal filling spaces by stitching the upper and lower ends with short stitches in a lattice pattern. , And a horizontal town tape, and a filling space 30 for inserting a filling nozzle is formed in a contact portion C between the vertical town tape 10 and the horizontal town tape 20 to form an adjacent filling space. The comrades are in a communicating state, and one of the vertical or horizontal town tapes forming one filling space is composed of a tape body having a length corresponding to one side of the filling space, By inserting a filling path forming piece 40 as a separate member into the non-sewn part 35 formed between the edge of one of the town tapes and the side surface of the other town tape or the side surface of the side fabric. The formation of the filling path And features.
