2. Description of the Related Art Conventionally, as a structure for attaching a covering material to an outer surface of a core body such as a chair or a sofa, there are known attachment structures as shown in FIGS. This structure is based on a core 52 of a chair 51 (a core material 5 made of wood, hard resin, or the like).
3 and a soft cushion material 54, a slab material 55, and the like. When the covering material 56 such as leather or cloth is stuck to the outer surface of the core member 52, the covering member 56 in the vicinity of the close overlap portion m of the cushioning material 54 on the seat and the back is prevented from wrinkling. 5
8, the cord 58 is engaged with the back side of the corresponding portion of the covering material 56, and is pulled obliquely downward to pull the covering material 56 into the close-contact overlapping portion m neatly.
6 is prevented from wrinkling. Incidentally, the lower edge peripheral portion of the covering material 56 is then fixed to the core 52 with a tucker needle 57 or the like, so that the chair 51 as shown in FIG. 9 is manufactured.

[0003]

However, in the conventional structure as described above, when the core 53 is made of a hard resin or the like, the core 5
A hole or the like for passing the string 58 must be made in a predetermined portion of the third member 3, and since the covering material 56 is fixed by the string 58, for example, even if the covering material 56 becomes dirty and it is desired to perform washing or the like, the tucker needle is used. It cannot be removed just by removing 57,
In particular, if the covering material 56 is a cloth or the like, the chair 51
If water is spilled from above, it is inconvenient because only the covering material 56 cannot be removed and dried.

Accordingly, the present invention enables the coating material 56 to be easily attached to and detached from the core 52, and the coating material 56 is drawn into the close-contact overlapping section m neatly, and wrinkles and the like are provided near the close-contact overlapping section m. It is an object of the present invention to provide a bonding structure that does not cause any problem.

[0005]

In order to achieve the above object, according to the present invention, a part of a covering material stretched on an outer surface of a core of a chair is drawn into a close-contact polymerized portion of the core according to the present invention. In the drawn-in structure, an anchoring material on one side of the hook-and-loop fastener is provided in or in the vicinity of the adhesion overlapping portion of the core body

You can do it. Here, for example, the boundary between the cushioning material of the seat portion and the back portion, or the adjacent seat portions in the case of a multi-seat chair, the boundary portion of the cushion material between the back portions, or other design properties For example, a contact concave portion or the like is included. In addition, a general crimping type surface fastener in which a male fastening member having a hard hook-shaped protrusion and a female fastening member having a soft ring-shaped loop engage with each other, A type having a relatively strong engaging force is more preferable.

The anchoring material attached to the core body may be either the male side or the female side, and can be attached to the outer surface of one side of the adhesively bonded portion by any method such as adhesion, fusion, integral molding, etc. The attachment portion of the anchoring material may be provided by bonding, fusion, integral molding, or the like to a core body such as a portion deeper than the close-contact overlapping portion. Also, the method of attaching the anchoring material attached to the coating material side is arbitrary, and for example, any method such as adhesion, fusion, sewing or the like can be applied. Here, the chairs include not only chairs but also sofas and the like.

[0008] According to claim 2, the engaging member attached to the core body side, and to be integrally formed with the core member when the core molding of the core body. Thus, if the core material at the same time as the molding at the core molding, joining operation or the like of the subsequent engaging member and the core member can be omitted.
Here, as a means for integrally molding the anchoring material and the core material , for example, when the core material is made of resin, the anchoring material is insert-molded.

[0011] According to claim 3, when integrally forming the core material and the engaging member and so as to mold the core material and the engaging member from the same material. If the same material is used as described above, for example, the bonding property at the time of insert molding or the like and the adhesive property at the time of the adhesive property are good, and the recycling is easy in disposal and the like.

According to a fourth aspect of the present invention, at least the close-contact overlapping portion at the boundary between the seat portion and the back portion is included as the close-contact overlapping portion of the core body. Such a boundary portion between the seat portion and the back portion is a portion where the structure of the close-contact overlapping portion for drawing in the coating material is frequently used in a chair or the like having a back portion, and the practical value is further increased by applying to such a portion. .

The coating material 6 can be easily removed simply by disengaging the, and the maintenance such as drying and washing can be easily performed.

Incidentally, since the upper surface and the like of the cushion material 4 are locally covered with the non-permeable cover material 10, even if water or the like is spilled, the water or the like does not penetrate into the interior of the cushion material 4, and The treatment is completed only by peeling the material 6 and drying the coating material 6.

By the way, the cover material 10 in the close overlapped portion m
Instead of attaching the binding material 8k to the core material 3 as shown in FIG. 6, the binding material 8k is attached to the core material 3 at a position deeper than the close overlapping portion m, and the inserted portion of the coating material 6 is attached to the tip of 6a on the other side. The engaging member 8j may be attached and engaged. In this case, the same effect as in the above example can be obtained. Also in this case, the material of the core material 3 and the material of the binding material 8k are the same, and for example, the
If k is integrated by insert molding, the joining operation can be omitted, and recycling at the time of disposal can be facilitated.

The present invention is not limited to the above embodiment. Those having substantially the same configuration as the matters described in the claims of the present invention and exhibiting the same functions and effects belong to the technical scope of the present invention. For example, as the contact overlap portion m, not only the boundary portion between the back portion and the seat portion, but also the seat portions in the case of multiple seats, the boundary portion between the back portions, or other design concave portions can be applied.

The type and fixing method of the anchoring members 8k and 8j are arbitrary, and the present invention can be applied not only to the chair 1 but also to a fastening structure of a covering member such as a sofa. Further, the cover member 10 covering the cushion member 4 may be omitted, and the anchoring member 8k may be directly molded or bonded directly to the cushion member 4, and the wrapping of the steel wire 12 into the insertion portion 6a is an essential requirement. is not.
