Description

  The present invention improves the decorative structure of the covering cushion, more specifically, the work of mounting the cover is labor-saving, can realize a good sitting comfort without impairing the flexibility of the cushion, and has a novel design The present invention relates to an open-collared decorative structure of a covering cushion that is not easily broken and has an excellent design.

  In general, when a cushion is used, a cover material for protecting the cushion body from dirt and damage is often used, and the cover material used at that time is also required to have a decorative property that can enhance the appearance of the cushion.

  And as a cover material having such decorativeness, what has been well known in the past has been enhanced by using a high-quality thick fabric such as quilt or fur as a material, Such thick fabrics have low rapid breathability, so the air released from the compressed cushion when seated is not easily escaped from the cover, thereby impairing the comfortable flexibility expected of the cushion. Dissatisfaction was heard about sitting comfort (for example, refer to Patent Document 1).

  In addition, in the case of a covering cushion, when the bag body is used with the padding filled in the cushion body, the padding is pushed from the part where the load is applied in the seating to the peripheral part where no load is applied, and the peripheral part expands. In some cases, the cover material was stretched, causing wrinkles and twists.

  In addition, when using the above bag-type cushion, the shape stability of the cushion itself is low, so when attaching the cover material, you must put the hand inside the cover and perform the cornering work as with the futon. It was very annoying.

Therefore, in the past, a device was devised to eliminate these problems by providing slits at the corners of the cover material, but slits were formed along the corner edges of the cover material as described in <Patent Document 2>. In the structure that is only provided, not only is the design unsightly when the cushion body is accommodated, but also the corner of the cover material where the load is concentrated in the vicinity of the slit and the slit is formed when the cushion is expanded due to the padding being offset. There was a problem that the part easily loses its shape.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to make it possible to save labor for mounting the cover and to impair the soft flexibility of the cushion. It is another object of the present invention to provide an open-collar-like decoration structure for a covering cushion that can realize a good sitting comfort and is excellent in design that is very innovative in design and hardly loses its shape.

  Means employed by the present inventor for solving the above-described problems will be described with reference to the accompanying drawings.

That is, the present invention relates to a cushion body 1 produced by filling a stuffing 11 into a bag 12; a sack member that can accommodate the cushion body 1, and at least one corner portion 21 of the corner portion. On the other hand, it is composed of an angular crack cover material 2 cut by a slit S inserted in the direction of the bisector of the bending angle,
In the state in which the cushion body 1 is accommodated in the bag of the cover material 2, both the cut end portions 21a and 21a in the corner portion 21 of the cover material 2 are folded back symmetrically outwardly, and the cushion is accommodated. It is characterized in that the back surface portion 23 of the cover material 2 is stably exposed in an open collar shape in a tension state by the swelling pressure of the main body 1.

  Moreover, in order to solve the said subject, in addition to the said means as needed, this invention employ | adopts the technical means of using the double fabric which bonded the surface material and the lining to the square crack cover material 2. FIG. Can do.

  Further, in order to solve the above-mentioned problems, the present invention is a technique in which a decorative fabric having a contrast significantly different from that of the front surface portion 22 is attached to the back surface portion 23 of the square crack cover material 2 in addition to the above-described means as necessary. Manual means can be employed.

  Moreover, in order to solve the said subject, this invention can employ | adopt the technical means of using a highly elastic raw material for the corner | angular part of the bag 12 in the cushion main body 1 in addition to the said means as needed. it can.

  Further, in order to solve the above-described problems, the present invention provides a technical means in which a storage pocket 26 is attached to the inside of the opening edge portion 25 in the back surface portion 23 of the square crack cover material 2 in addition to the above-described means as necessary. Can be adopted.

  In the present invention, the cushion body is housed in a cover material in which at least one corner is cut by a slit in the bisector direction, and both the corners in which the slit is formed in the cover material. Since the cut end portion of the cover is symmetrically folded outward, the cover lining can be stably exposed in an open collar shape in a tension state due to the inflation pressure of the accommodated cushion body. It is possible to obtain a novel design effect in which an impressive contrast is formed between the front surface, the back surface of the folded portion, and the cover material of the cushion body exposed from the opening.

  Moreover, by folding back the cut end at the corner of the cover material to create a large opening, not only can the padding pushed out to the corner of the cushion exposed from the opening escape, but also the cover material Since the opening edge portion can be doubled and the stretching strength can be improved, even if the padding is shifted and the corner portion of the cushion expands, the corner portion of the cover material is not easily deformed.

  In this case, since the cut end portion of the cover material is folded back symmetrically, the load due to the expansion of the cushion corner portion does not concentrate on the folded portion on one side of the opening edge portion, and both folded portions are folded. Evenly distributed in parts.

  In addition, even when fabric with poor ventilation is used for the cover material, air can be smoothly released from the openings formed in the corners of the cover material, so the cushion can be softly subducted The feeling is not impaired and a comfortable sitting comfort can be realized.

  In addition, regarding the work of attaching the cover material to the cushion body, the corners of the cushion body can be easily adjusted by inserting a hand through the slit at the corner, thereby saving labor in the attachment work. Can also be achieved.

  Therefore, according to the present invention, a covering cushion having a very original design and excellent functionality and usability can be provided. Therefore, the practical utility value of the present invention is very high.

“Example 1”
Embodiment 1 of the present invention is shown in FIGS. In the figure, what is indicated by reference numeral 1 is a cushion body, and what is indicated by reference numeral 2 is a square crack cover material. What is indicated by reference numeral 3 is a sofa.

  Next, the configuration of the first embodiment will be described below. First, in the first embodiment, the cushion body 1 is manufactured by filling the stuffing 11 into the bag 12, and the cushion body 1 is manufactured in a sack shape, and predetermined corner portions 21 and 21 are formed evenly. It is accommodated in the angular crack cover material 2 cut by the slit S formed in the direction of the bisector of the bending angle of the corner 21 (see FIGS. 1 and 2).

  In addition, a cover member 2 having a decorative surface on the front surface portion 22 and the back surface portion 23 is used as the square crack cover material 2, and a fastener member 24 is attached to the cover material 2 so that the cushion body 1 can be freely inserted and removed. Yes.

  And in the state which accommodated the cushion main body 1 in the square crack cover material 2, as shown in FIG. 3, by fold | folding both the cutting edge parts 21a * 21a in the corner part 21 of the cover material 2 symmetrically outside, As shown in FIG. 4, the cover lining 23 can be exposed in an open collar shape, thereby forming a decorative surface with a striking contrast due to the front and back surfaces 22 and 23 of the cover material and the cover material of the cushion body. can do.

  In addition, the cut | disconnected edge part 21a * 21a of the square crack cover material 2 can maintain the state stably exposed in the tension | tensile_strength state by the swelling pressure of the accommodated cushion main body 1. FIG.

  In addition, if a decorative fabric having a contrast significantly different from that of the front surface portion 22 is used for the back surface portion 23 of the folded back cover material 2, the folded shape of the cut end portions 21a and 21a of the cover material 2 and three types of decorative fabric Variations in design can be diversified by combination.

  Further, in the first embodiment, the decorative fabric is used only for the both end portions of the cushion body 1 exposed from the opening R of the corner portion 21 of the square crack cover material 2, so that the central portion of the cushion body 1 is absorbed and released. The functionality of the cushion body 1 is maintained using a highly breathable fabric excellent in moisture.

  In addition, a reversible structure can be obtained by using a double fabric in which a decorative surface and a lining material are laminated to the square crack cover material 2, and in this case, the square crack cover material 2 is double. Since the strength is also improved, it is not necessary to apply a reinforcing resin coating (commonly known as “backing”) on the back surface, and it is difficult to accommodate the cushion body 1 in the cover material 2 due to the frictional resistance of the resin coating layer. Nor.

  On the other hand, the padding pushed out to the corner of the cushion body 1 exposed from the opening R by creating the large opening R by folding back the cut end portions 21a and 21a at the corner 21 of the square crack cover material 2 11 can be released, thereby reducing the load caused by the swelling pressure of the cushion body 1 that causes wrinkles and twisting of the cover material 2, thereby preventing the cover material from being deformed.

  In addition, if the highly elastic material which is easy to expand is used for the corner | angular part of the cushion main body 1, the load concerning the square crack cover material 2 can be reduced more.

  In addition, the opening edge 25 of the square crack cover material 2 is doubled by folding to increase the stretching strength. Therefore, even if the padding 11 is offset and the corner of the cushion body 1 expands, the corner angle of the cover material 2 is increased. Part 21 is less likely to lose its shape.

  In Example 1, a granular foamed resin material having fluidity inside the bag 12 is used as the stuffing 11 of the cushion body 1. However, as this stuffing 11, a fluid gel or gas is used. Also, even when using cotton material or feather material as the stuffing 11 that gradually shifts to the end of the cushion by receiving repeated load even if it does not have remarkable fluidity in the bag 12 The same effect can be obtained.

  On the other hand, even when a fabric with low air permeability is used for the square crack cover material 2, air can be smoothly discharged from the opening R of the cover material 2, so that the cushion body 1 has a soft and soft feel. It is possible to achieve a good sitting comfort without being damaged.

  Moreover, since the opening R provided in the cover member 2 has a function of releasing heat and releasing moisture, it is difficult for stuffiness to occur during sitting, and the cushion body 1 is used as a seat 31 or a backrest 32 of the sofa 3. If used, the comfortable sofa 3 can be produced (see FIG. 5).

  It should be noted that the cornering cover material 2 can be attached to the cushion body 1 because the corner can be adjusted by simply inserting a hand from the slit S of the corner portion 21 and picking out the corner portion of the cushion body 1. Will be very simple.

“Example 2”
Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, a storage pocket 26 is attached to the inside of the opening edge 25 in the back surface 23 of the square crack cover material 2. Therefore, the covering cushion can be used for convenient storage (see FIG. 6).

“Example 3”
Next, a third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, the cover member 2 is attached to the cushion body 1 in a stacked manner, and when the cut ends 21a and 21a 'of both cover members 2 and 2' are folded back, Since the back surface portion 23 of the cover material 2 and the back surface portion 23 ′ of the outer cover material 2 ′ appear to overlap, the design effect of the Date collar style can be achieved (see FIG. 7).

  The design effect of the Date collar style can also be obtained by attaching a backing material 27 that makes it difficult for the cut end portion 21a of the square crack cover material 2 to turn back when folded, as shown in FIG. .

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims. For example, The shape of the cushion body 1 and the square crack cover material 2 is not limited to a rectangular shape having a right-angled corner, but a triangular shape or a star shape having an acute corner as shown in FIG. Alternatively, it may be a polygonal shape having an obtuse corner as shown in FIG.

  Further, as the fabric of the cushion main body 1 and the square crack cover material 2, not only the fabric but also fur, artificial leather, resin sheet and the like can be appropriately selected, and any of them belongs to the technical scope of the present invention.

  In recent years, various types of cushions have been sold due to diversification of tastes, and in particular, cushions used for sofas are required to have excellent design properties that can realize original sofa designs. In addition, when used for a sofa, it is also important that the comfort of wearing is not impaired.

  Under such circumstances, the open-collar decoration structure of the covering cushion according to the present invention is a useful technique that not only forms an original and innovative sofa design, but also takes into account the functionality of the sofa. For some reason, the demand in the market is great and its industrial utility value is very high.
