Description

本発明は、ソファに被せられるソファカバーに関する。 The present invention relates to a sofa cover that can be put on a sofa.

従来、ソファに被せられるソファカバーが知られている（例えば、特許文献１参照）。ここで、ソファは、座部と、座部の後方に設けられた背部と、座部の左・右両側にそれぞれ設けられた左・右肘掛部と、を有している。そして、この従来技術のソファカバーは、ソファ全体（背部の前面を覆う部分、座部の上面を覆う部分、及び、左・右肘掛部を覆う部分）に被せられる１枚布構造となっている。 Conventionally, a sofa cover that can be put on a sofa is known (see, for example, Patent Document 1). Here, the sofa has a seat portion, a back portion provided behind the seat portion, and left and right elbow rest portions provided on both the left and right sides of the seat portion, respectively. The sofa cover of this conventional technique has a single cloth structure that covers the entire sofa (the part that covers the front surface of the back, the part that covers the upper surface of the seat, and the part that covers the left and right accoudoirs). ..

実用新案登録第３１７６５８５号公報（図１等）Utility Model Registration No. 3176585 (Fig. 1 etc.)

上記従来技術のソファカバーは、ソファ全体に被せられる１枚布構造であることから大型化することとなる。この結果、ソファカバーの張り替え時や交換時等において、ソファからの取り外しやソファへの装着が大掛かりな作業となり、専門知識のない通常のユーザでは対応することが難しいという問題があった。 Since the sofa cover of the above-mentioned conventional technique has a single cloth structure that covers the entire sofa, the size of the sofa cover will be increased. As a result, when the sofa cover is replaced or replaced, it becomes a large-scale work to remove it from the sofa and attach it to the sofa, and there is a problem that it is difficult for a normal user without specialized knowledge to handle it.

本発明の目的は、専門知識のない通常のユーザでも簡単に取り外しや装着ができるソファカバーを提供することにある。 An object of the present invention is to provide a sofa cover that can be easily removed and attached even by an ordinary user without specialized knowledge.

上記目的を達成するために、本願発明は、座部と、座部の後方に設けられた背部と、座部の左・右両側にそれぞれ設けられた左・右肘掛部と、を有するソファに被せられるソファカバーであって、座部及び背部のうち少なくとも背部を覆う、略平布状の背覆い部と、左肘掛部を略包含するように覆う左肘掛覆い部と、右肘掛部を略包含するように覆う右肘掛覆い部と、を有し、背覆い部の左肘掛覆い部側の第１縁部と、左肘掛覆い部の背覆い部側の第２縁部とを、左オープンファスナーによって係合・離脱自在に接続し、背覆い部の右肘掛覆い部側の第３縁部と、右肘掛覆い部の背覆い部側の第４縁部とを、右オープンファスナーによって係合・離脱自在に接続したことを特徴とする。 In order to achieve the above object, the present invention relates to a sofa having a seat portion, a back portion provided behind the seat portion, and left and right accoudoir portions provided on both left and right sides of the seat portion, respectively. The sofa cover to be covered, which is a substantially flat cloth-like back cover that covers at least the back of the seat and back, a left accoudoir that covers the left accoudoir so as to substantially include the left accoudoir, and a right accoudoir. It has a right accoudoir covering portion that covers the back covering portion, and the first edge portion of the back covering portion on the left elbow hanging covering portion side and the second edge portion of the left elbow hanging covering portion on the back covering portion side are left open. Engagement / detachment is possible with a fastener, and the third edge of the back cover on the right accoudoir cover side and the fourth edge of the right accoudoir cover on the back cover side are engaged with the right open fastener. -It is characterized by being connected freely.

本願発明のソファカバーにおいては、左右の肘掛覆い部と、中央側の背覆い部と、をオープンファスナーにより係合・離脱自在としている。詳細には、背覆い部の左肘掛覆い部側の第１縁部と、左肘掛覆い部の背覆い部側の第２縁部とを、左オープンファスナーによって係合・離脱自在に接続し、背覆い部の右肘掛覆い部側の第３縁部と、右肘掛覆い部の背覆い部側の第４縁部とを、右オープンファスナーによって係合・離脱自在に接続している。これにより、従来のような大型の１枚布構造のソファカバーを採用する場合に比べて、ソファカバーの張り替え時や交換時等において、大掛かりな作業が必要なくなり、専門知識のない通常のユーザでも簡単に取り外し及び装着ができる。 In the sofa cover of the present invention, the left and right elbow rest covering portions and the back covering portion on the center side are freely engaged with and detached by an open fastener. Specifically, the first edge portion of the back cover portion on the left accoudoir cover side and the second edge portion of the left accoudoir cover portion on the back cover portion side are connected by a left open fastener so as to be freely engaged and detached. The third edge portion of the back cover portion on the right elbow rest cover side and the fourth edge portion of the right elbow rest cover portion on the back cover portion side are freely engaged and detached by a right open fastener. As a result, compared to the case of adopting a large single-cloth structure sofa cover as in the past, large-scale work is not required when replacing or replacing the sofa cover, and even ordinary users without specialized knowledge can use it. Easy to remove and install.

また、上記のように、ソファカバーをオープンファスナーによる分割構造としたことで１つのピース（左・右肘掛覆い部や背覆い部等）が小さくなり、廃棄せずに適宜にクリーニングして再利用することが可能になる。この結果、ソファカバーをリサイクル化することもできる。 In addition, as described above, the sofa cover has a split structure with open fasteners, which makes one piece (left / right accoudoir cover, back cover, etc.) smaller, and can be appropriately cleaned and reused without being discarded. It will be possible to do. As a result, the sofa cover can be recycled.

以上の構成により、本願発明によれば、専門知識のない通常のユーザでも簡単に取り外しや装着を行うことができる。 With the above configuration, according to the present invention, even a normal user without specialized knowledge can easily remove and attach the device.

＜実施形態の効果＞
以上説明したように、本実施形態のソファカバー１０においては、左右の肘掛覆い部３０，４０と、中央側の背覆い部２０と、をオープンファスナー７０，８０により係合・離脱自在としている。詳細には、背覆い部２０の左肘掛覆い部３０側の第１縁部７１と、左肘掛覆い部３０の背覆い部２０側の第２縁部７２とを、左オープンファスナー７０によって係合・離脱自在に接続し、背覆い部２０の右肘掛覆い部４０側の第３縁部８１と、右肘掛覆い部４０の背覆い部２０側の第４縁部８２とを、右オープンファスナー８０によって係合・離脱自在に接続している（図２及び図１０参照）。これにより、従来のような大型の１枚布構造のソファカバーを採用する場合に比べて、ソファカバー１０の張り替え時や交換時等において、大掛かりな作業が必要なくなり、専門知識のない通常のユーザでも簡単に取り外し及び装着ができる。
なお、ソファカバー１０の材質としては、上記のような簡単な取り外し及び装着が可能な限りにおいて特に限定されるものではないが、本実施形態の特徴の１つとして、ソファカバー１０の材質として特に革材料を用いることもできる。すなわち、従来のような大型の１枚布構造のソファカバーの場合、材質を革材料とすると重量が相当重くなってしまい、取り外し及び装着に多大な労力を要することとなる。また、革は表面が固くユーザによっては使用感があまりよくない上、使用するにつれて表面が延びる性質があることから上記大型の１枚布構造の場合には延びが目立ってしまい美観を損ねる、という難点がある。したがって、ソファカバーの材質として、通常は革材料は用いられていなかった。しかしながら、本実施形態のソファカバー１０では、上述のように、左肘掛覆い部３０と、右肘掛覆い部４０と、背覆い部２０との３つに分かれた、いわばパーツ分割した構成となっている。すなわち、左肘掛覆い部３０や、右肘掛覆い部４０や、背覆い部２０、の各パーツ１つ１つで見ると、前述の１枚の布構造に比べればかなり大きさが小さい。これにより、それら各パーツを革材料で構成したとしても、パーツごとの重量はそれほど大きくはならず、また上記の使用後の延び量も前述ほどは目立たない。すなわち、本実施形態によれば、従来、材質として用いるのは困難又は不可能であった革材料によりのソファカバー１０を製造することができる、という効果もある。 <Effect of embodiment>
As described above, in the sofa cover 10 of the present embodiment, the left and right arm rest covering portions 30 and 40 and the back covering portion 20 on the center side are freely engaged and detached by the open fasteners 70 and 80. Specifically, the first edge portion 71 on the left accoudoir covering portion 30 side of the back covering portion 20 and the second edge portion 72 on the back covering portion 20 side of the left accoudoir covering portion 30 are engaged with each other by the left open fastener 70. The right open fastener 80 connects the third edge 81 on the right elbow cover 40 side of the back cover 20 and the fourth edge 82 on the back cover 20 side of the right accoudoir 40 so as to be detachably connected. (See FIGS. 2 and 10). As a result, compared to the case of adopting a large single-cloth structure sofa cover as in the past, a large-scale work is not required when the sofa cover 10 is replaced or replaced, and a normal user without specialized knowledge is required. But it can be easily removed and installed.
The material of the sofa cover 10 is not particularly limited as long as it can be easily removed and attached as described above, but one of the features of the present embodiment is that the material of the sofa cover 10 is particularly limited. Leather materials can also be used. That is, in the case of a conventional large sofa cover having a single cloth structure, if the material is leather, the weight becomes considerably heavy, and a great deal of labor is required for removal and mounting. In addition, leather has a hard surface and is not very comfortable to use depending on the user, and since the surface has the property of extending as it is used, the extension becomes conspicuous in the case of the above-mentioned large single cloth structure, which spoils the appearance. There are drawbacks. Therefore, leather material was not usually used as the material of the sofa cover. However, in the sofa cover 10 of the present embodiment, as described above, the sofa cover 10 is divided into three parts, that is, a left elbow rest cover portion 30, a right elbow rest cover portion 40, and a back cover portion 20, so to speak. There is. That is, when looking at each of the parts of the left elbow rest covering portion 30, the right elbow rest covering portion 40, and the back covering portion 20, the size is considerably smaller than that of the above-mentioned single cloth structure. As a result, even if each of these parts is made of a leather material, the weight of each part does not become so large, and the amount of extension after use is not as noticeable as described above. That is, according to the present embodiment, there is also an effect that the sofa cover 10 made of a leather material, which has been difficult or impossible to use as a material in the past, can be manufactured.

また、上記のように、ソファカバー１０をオープンファスナー７０，８０による分割構造としたことで１つのピース（左・右肘掛覆い部３０，４０や背覆い部２０等）が小さくなり、廃棄せずに適宜にクリーニングして再利用することが可能になる。この結果、ソファカバー２０をリサイクル化することもできる。 Further, as described above, since the sofa cover 10 has a split structure with open fasteners 70 and 80, one piece (left / right accoudoir covering portions 30, 40, back covering portion 20, etc.) becomes smaller and is not discarded. It will be possible to properly clean and reuse it. As a result, the sofa cover 20 can be recycled.

また、本実施形態では特に、ソファカバー１０は、座部２を覆う略平布状の座覆い部６０をさらに有している。そして、座覆い部６０は、少なくとも着座面に畳部分を備えている。これにより、ソファ１全体に和風のくつろぎ感を与えることができる。さらに、畳に使用される藺草には空気清浄効果や消臭効果があるため、座覆い部６０に上記畳部分が備えられることにより、周囲空間の空気清浄化及び消臭を図ることができる。またその結果、例えばこの座覆い部６０を備えたソファカバー１０を子供の学習環境に配置することによって、子供に静かな落ち着き感を与えることができる等の精神的な効果を得ることもできる。 Further, in the present embodiment, in particular, the sofa cover 10 further has a substantially flat cloth-shaped seat covering portion 60 that covers the seat portion 2. The seat covering portion 60 is provided with a tatami mat portion at least on the seating surface. This makes it possible to give a Japanese-style relaxing feeling to the entire sofa 1. Further, since the rush used for tatami has an air purifying effect and a deodorizing effect, it is possible to purify and deodorize the air in the surrounding space by providing the tatami mat portion in the seat covering portion 60. As a result, for example, by arranging the sofa cover 10 provided with the seat cover 60 in the learning environment of the child, it is possible to obtain a mental effect such as giving the child a quiet and calm feeling.

また、本実施形態では特に、左オープンファスナー７０の左右方向位置が、ソファ１における背部３と左肘掛部４との第１境界部位Ｂ１の左右方向位置と略一致している。また、右オープンファスナー８０の左右方向位置が、ソファ１における背部３と右肘掛部５との第２境界部位Ｂ２の左右方向位置と略一致している。しかも、第１境界部位Ｂ１では、互いに左右方向に対向する背部２及び左肘掛部４の端部同士の間に生じる窪みにより第１窪み線Ｌ１が形成され、第２境界部位Ｂ２では、互いに左右方向に対向する背部２及び右肘掛部４の端部同士の間に生じる窪みにより第２窪み線Ｌ２が形成されている。そして、左オープンファスナー７０の左右方向位置が、ソファ１の第１窪み線Ｌ１の左右方向位置と略一致しており、右オープンファスナー８０の左右方向位置が、ソファ１の第２窪み線Ｌ２の左右方向位置と略一致している。これにより、ソファカバー１０の境界とソファ１の境界とが一致するため、特に取り外し・装着が簡単にできる。また、ソファカバー１０を装着したソファ１の外観の見た目に違和感がなくなり、美観を向上できる。 Further, in the present embodiment, in particular, the left-right position of the left open fastener 70 substantially coincides with the left-right position of the first boundary portion B1 between the back portion 3 and the left accoudoir portion 4 on the sofa 1. Further, the left-right position of the right open fastener 80 substantially coincides with the left-right position of the second boundary portion B2 between the back portion 3 and the right elbow rest portion 5 on the sofa 1. Moreover, in the first boundary portion B1, the first recess line L1 is formed by the recesses formed between the ends of the back portion 2 and the left accoudoir portion 4 facing each other in the left-right direction, and in the second boundary portion B2, the left and right sides of each other are formed. The second dent line L2 is formed by the dents formed between the ends of the back portion 2 and the right accoudoir portion 4 facing in the direction. The left-right position of the left open fastener 70 substantially coincides with the left-right position of the first recess line L1 of the sofa 1, and the left-right position of the right open fastener 80 is the left-right position of the second recess line L2 of the sofa 1. It is almost the same as the horizontal position. As a result, the boundary of the sofa cover 10 and the boundary of the sofa 1 coincide with each other, so that the sofa cover 10 can be particularly easily removed and attached. In addition, the appearance of the sofa 1 to which the sofa cover 10 is attached does not look strange, and the aesthetic appearance can be improved.

また、本実施形態では特に、左オープンファスナー７０が、第１縁部７１及び第２縁部７２のうちソファ１の背面側に配置される部分のみに設けられており、右オープンファスナー８０が、第３縁部８１及び第４縁部８２のうちソファ１の背面側に配置される部分のみに設けられている。これにより、オープンファスナー７０，８０が背覆い部２０の縁部や肘掛覆い部３０，４０の縁部の全寸法にわたって設けられる場合に比べて、オープンファスナーの長さを短くすることができ、低コスト化を図ることができる。 Further, in the present embodiment, in particular, the left open fastener 70 is provided only on the portion of the first edge portion 71 and the second edge portion 72 arranged on the back side of the sofa 1, and the right open fastener 80 is provided. It is provided only on the portion of the third edge portion 81 and the fourth edge portion 82 that is arranged on the back surface side of the sofa 1. As a result, the length of the open fastener can be shortened as compared with the case where the open fasteners 70 and 80 are provided over the entire dimensions of the edges of the back covering portion 20 and the edges of the armrest covering portions 30 and 40, which is low. It is possible to reduce the cost.

また、本実施形態では特に、左肘掛覆い部３０が、左肘掛部４のうちソファ１外側となる部分を覆う第１面部３２と、左肘掛部４のうちソファ１内側となる部分を覆う第２面部３３と、を有し、右肘掛覆い部４０が、右肘掛部５のうちソファ１外側となる部分を覆う第３面部４２と、右肘掛部５のうちソファ１内側となる部分を覆う第４面部４３と、を有している。そして、第２面部３３のうち座部２の左端部と重なる部分における高さ寸法が、第１面部３２の高さ寸法に比べて小さくなっており、第４面部４３のうち座部２の右端部と重なる部分における高さ寸法が、第３面部４２の高さ寸法に比べて小さくなっている。これにより、肘掛覆い部３０，４０の袋状形状が左右均等でなくなり、その分だけ左・右肘掛覆い部３０，４０のサイズを小さくできる。 Further, in the present embodiment, in particular, the left accoudoir covering portion 30 covers the first surface portion 32 of the left accoudoir portion 4 covering the portion outside the sofa 1 and the left accoudoir portion 4 covering the portion inside the sofa 1.
