Description
【０００１】[0001]
本考案は椅子に関する。 The present invention relates to a chair.
【０００２】[0002]
従来、座と背もたれとを別個に製造して、それぞれ脚に取付けた構造の椅子が 公知である。 Conventionally, there is known a chair having a structure in which a seat and a backrest are separately manufactured and attached to respective legs.
【０００３】 上記公知例のごとき椅子は、座と背もたれとをそれぞれ別個に製造することに 加えて、それぞれ別個に脚に組み付ける必要があるので、工程数が多くコスト高 となる問題があった。In the chair of the above-mentioned known example, in addition to manufacturing the seat and the backrest separately, it is necessary to assemble them separately to the legs, so that there is a problem that the number of steps is large and the cost is high.
【０００４】[0004]
本考案は、座と背もたれの製造及び組み付けが簡略化して工程数が減少し、コ スト低減が可能となる椅子の提供を目的とする。 An object of the present invention is to provide a chair in which manufacturing and assembling of a seat and a backrest are simplified, the number of steps is reduced, and cost is reduced.
【０００５】[0005]
上記目的を達成するために、本考案における椅子は、座の基体部１と背もたれ の基体部２とが一体的なブロー成形品であることを特徴とする構成としたもので ある。 In order to achieve the above object, the chair according to the present invention is characterized in that the seat base portion 1 and the backrest base portion 2 are integrally formed by blow molding.
【０００６】[0006]
以下、図示した本考案の実施例について説明する。まず、符号１が座の基体部 であり、符号２が背もたれの基体部である。これら座の基体部１と背もたれの基 体部２はプラスチック製で、ブロー成形により一体的に製造されている。座の基 体部１と背もたれの基体部２は共に中空部３，４を有して若干の厚みがあり、座 の基体部１の上面には前後方向の溝５が、又、背もたれの基体部２の前面には上 下方向の溝６がそれぞれ形成されている。尚、座の基体部１におけるそれぞれの 中空部３と背もたれの基体部２におけるそれぞれの中空部４は互いに連通してい る。座の基体部１の上面及び背もたれの基体部２の前面には、それぞれ、座の上 敷７と、背もたれの背当て８とが固定されている。座の上敷７と背もたれの背当 て８は、共に基板９，１０の上にクッション材を載せてその表面をソフトレザー や布などの張包み材で覆った構造となっていて、基板９，１０の裏面には突起１ １，１２を設けて、その突起１１，１２を座の基体部１の上面及び背もたれの基 体部２の前面にそれぞれ設けた凹部１３，１４に嵌合させて、その凹部１３，１ ４内に接着剤によって固着されている。 Hereinafter, the illustrated embodiment of the present invention will be described. First, reference numeral 1 is a seat base portion, and reference numeral 2 is a backrest base portion. The base portion 1 of these seats and the base portion 2 of the backrest are made of plastic and are integrally manufactured by blow molding. The base part 1 of the seat and the base part 2 of the backrest both have hollow portions 3 and 4 and are of a slight thickness. A groove 5 in the front-rear direction is formed on the upper surface of the base part 1 of the seat, and also the base part of the backrest. Grooves 6 are formed in the upper and lower directions on the front surface of the portion 2. Each hollow portion 3 of the seat base portion 1 and each hollow portion 4 of the backrest base portion 2 communicate with each other. A seat top 7 and a backrest backrest 8 are fixed to the upper surface of the base body 1 of the seat and the front surface of the base body 2 of the backrest, respectively. The seat overlay 7 and the backrest back 8 both have a structure in which a cushion material is placed on the substrates 9 and 10 and the surface thereof is covered with a wrapping material such as soft leather or cloth. Protrusions 11 and 12 are provided on the rear surface of 10, and the protrusions 11 and 12 are fitted into recesses 13 and 14 provided on the upper surface of the base portion 1 of the seat and the front surface of the base portion 2 of the backrest, respectively. The concave portions 13 and 14 are fixed by an adhesive.
【０００７】 また、座の基体部１と背もたれの基体部２における両側の側面部にそれぞれ肘 掛け１５，１６をネジ１７により取付けている。この肘掛け１５，１６も座の基 体部１及び背もたれの基体部２と同一の材料でブロー成形されたものである。Further, armrests 15 and 16 are attached by screws 17 to the side surface portions on both sides of the seat base portion 1 and the backrest base portion 2, respectively. The armrests 15 and 16 are also blow-molded with the same material as that of the base portion 1 of the seat and the base portion 2 of the backrest.
【０００８】 座の基体部１は、脚１８の上端に設けた取付台１９に対しネジ２０によって固 定されている。脚１８はキャスター２１により移動可能で、且つレバー２２の操 作により作動するガスを利用した昇降機構２３を備えている。取付台１９は後端 がバネ２４により支持されていて、その後端部が上下方向に揺動自在となってい る。従って、この取付台１９に固定された座の基体部１と、座の基体部１に一体 化した背もたれの基体部２とが前後方向にロッキングするようになっている。The base portion 1 of the seat is fixed by screws 20 to a mount 19 provided on the upper ends of the legs 18. The leg 18 is movable by a caster 21, and is provided with an elevating mechanism 23 using gas that is operated by operating a lever 22. A rear end of the mounting base 19 is supported by a spring 24, and a rear end of the mounting base 19 is vertically swingable. Therefore, the base body portion 1 of the seat fixed to the mounting base 19 and the base body portion 2 of the backrest integrated with the base body portion 1 of the seat are locked in the front-rear direction.
【０００９】[0009]
本考案の椅子は上記の通り、座の基体部１と背もたれの基体部２とが一体的な ブロー成形品であることを特徴とするので、座と背もたれの一部が同時に製造さ れ、且つ座の基体部１のみを組み付ければよいので、製造及び組み付けが簡略化 して工程数が減少することになり、コスト低減が達成されるものである。 As described above, the chair of the present invention is characterized in that the seat base portion 1 and the backrest base portion 2 are integrated blow-molded products, so that the seat and the backrest are partially manufactured at the same time, and Since only the base portion 1 of the seat needs to be assembled, the manufacturing and assembling are simplified, the number of steps is reduced, and the cost is reduced.
