Description

本発明は、座部の周縁に把持部材を配置した椅子に関する。 The present invention relates to a chair child placing the gripping member to the peripheral edge of the seat.

従来、座部の周縁に沿って棒材を配置した椅子が知られている（例えば、特許文献１参照）。この棒材は座部を支持するものであるが、脚の弱った高齢者や身体の不自由な人が椅子に座ったり椅子から立ち上がる際には、これを手すりのように掴んで身体を支えることがある。
しかし、座部を支持する棒材にはクッション材を被せてあるので、把持した時にクッション材が滑って危険であり、把持を繰り返すとクッション材の周囲部がちぎれて、椅子自体の耐久性が低下してしまう。 Conventionally, a chair is known in which bars are arranged along the periphery of a seat (see, for example, Patent Document 1). This bar supports the seat, but when an elderly person with a weak leg or a person with a physical disability sits on a chair or stands up from a chair, it grips it like a handrail to support the body Sometimes.
However, since the bar material supporting the seat is covered with a cushion material, the cushion material slips when gripped, and it is dangerous to repeat the grip, and the surrounding portion of the cushion material will tear off, and the durability of the chair itself will be reduced. It will decline.

また、本出願人は、先に、椅子の座部上面に配置された座面シートの周縁を外方へはりだして、その先端を下方へ屈曲して形成した把持体を提案した（特許文献２参照）。
この把持体は、下方の開口部へ指先を挿入し、クッション材とは独立して握ることができるので、安定性が高く、クッション材も劣化しない。
しかし、座面シートと一体に形成されているため全く保形性が無く、把持する部分が扁平なので、しっかり握るためにはある程度の握力を必要とする。 Further, the present applicant has previously proposed a gripping body formed by protruding the periphery of a seating surface sheet disposed on the upper surface of the seat portion of the chair outward and bending the tip downward (Patent Document). 2).
Since this gripper can insert a fingertip into a lower opening and can grasp it independently of the cushion material, the grip body has high stability and the cushion material does not deteriorate.
However, since it is formed integrally with the seat surface sheet, there is no shape retaining property and the gripping portion is flat, so that a certain gripping force is required to grip firmly.

本発明が解決しようとする課題は、自由な形状に曲がり、把持しやすい把持部材を座部の周縁に取り付けた椅子を提供することにある。 The problem to be solved by the present invention is to provide a chair that is bent into a free shape and has a gripping member that is easy to grip attached to the periphery of the seat .

本発明の椅子は、座部の周縁に把持部材を取り付けて成り、該把持部材は、可撓性を有し、周方向に沿う多数の補強リブを並設すると共に、指を挿入可能な軸方向に沿う切れ目を全長に亘って形成して成る筒体を二重に重ね、前記重ねた筒体の外周面を前記座部の上面から延びる表カバーで被覆すると共に、内周面を前記座部の側面から立ち上がった裏カバーで被覆し、該表カバー及び裏カバーの端部を重ねた筒体の間に挿入して固定して形成されている。
前記筒体は、一部に切れ目を形成した円形又は楕円形の断面を有すると良い。 The chair of the present invention is formed by attaching a gripping member to the periphery of the seat, and the gripping member is flexible and includes a number of reinforcing ribs along the circumferential direction, and a shaft into which a finger can be inserted. The cylinder formed by the cut along the direction is overlapped twice, the outer peripheral surface of the stacked cylinder is covered with a front cover extending from the upper surface of the seat portion , and the inner peripheral surface is covered with the seat covered with back cover stood up from the side parts are formed and fixed by inserting between the said surface cover and the back cover end of the superimposed tubular body.
The cylindrical body may have a circular or elliptical cross section with a cut in part.

請求項１に係る発明によれば、可撓性を有して様々な方向に屈曲する筒体を周縁に装着してあるので、身体障害者や高齢者の身動きを助けることができ、可撓性があるため、身体に当たった時に不快感を与え難い。
また、筒体の切れ目に指を掛けて外面を掌で握ることにより確実に把持することが可能であり、しかも、補強リブを設けてあるため筒体の断面が変形し難く、切れ目の部分から開いてしまう心配がない。 According to the first aspect of the present invention, since the cylindrical body that is flexible and bends in various directions is attached to the periphery, the movement of the physically handicapped and the elderly can be assisted. Due to its nature, it is difficult to feel uncomfortable when it hits the body.
In addition, it is possible to hold the outer surface with a palm by placing a finger on the cut of the cylinder, and because the reinforcing rib is provided, the cross section of the cylinder is not easily deformed. There is no worry of opening.

さらに、筒体の外周面及び内周面をそれぞれ表カバーと裏カバーとで被覆してあるので、手触りが柔らかくなるばかりか、デザイン的にも優れたものとなり、筒体を二重にしてあるため強度が増し、表カバーと裏カバーの端部どうしを縫い合わせる必要が無く、カバー端部が外面に現れないので仕上がりが美しい。
請求項２に係る発明によれば、断面が掌に馴染んだ形状で把持しやすい。 Furthermore, the outer and inner surfaces of the cylinder are covered with a front cover and a back cover, respectively, so that the touch is soft and the design is excellent, and the cylinder is doubled. Therefore, the strength is increased, there is no need to sew the ends of the front cover and the back cover, and the end of the cover does not appear on the outer surface, so the finish is beautiful.
According to the invention which concerns on Claim 2, it is easy to hold | grip with the shape which the cross section adapted to the palm.

以下本発明を詳細に説明する。
本発明の実施例に係る把持部材を形成する筒体１は、図１及び図２に示すように、可撓性を有し、指を挿入可能な軸方向に沿う切れ目３を全長に亘って形成してあり、図４に示すように、一部に切れ目３を形成した弧状或いは楕円弧状の断面を有する。
筒体１は、図３に示すように、２枚の合成樹脂シート１ａ、１ｂを重ね合わせるとともに、２枚の合成樹脂シート１ａ、１ｂの間に周方向に沿う細いパイプ２ａを多数配置して形成される。パイプ２ａを設置したことにより、筒体１の外周面には周方向に沿う多数の補強リブ２が適宜間隔ごとに形成される（図１、図２）。
なお、筒体１の直径は、握りやすいように３０〜５０ｍｍとする。 The present invention will be described in detail below.
As shown in FIGS. 1 and 2, the cylindrical body 1 forming the gripping member according to the embodiment of the present invention has flexibility and has a cut 3 along the axial direction in which a finger can be inserted over the entire length. As shown in FIG. 4, it has an arc-shaped or elliptical arc-shaped cross section in which a cut 3 is partially formed.
As shown in FIG. 3, the cylindrical body 1 has two synthetic resin sheets 1a and 1b overlapped, and a large number of thin pipes 2a along the circumferential direction are arranged between the two synthetic resin sheets 1a and 1b. It is formed. By installing the pipe 2a, a large number of reinforcing ribs 2 along the circumferential direction are formed at appropriate intervals on the outer peripheral surface of the cylindrical body 1 (FIGS. 1 and 2).
In addition, the diameter of the cylinder 1 shall be 30-50 mm so that it may be easy to grasp.

この筒体１は、切れ目３に指先を挿入して掌で握ることにより、確実に把持することができ、補強リブ２を設けてあるため、握って力を加えても筒体１の断面が大きく広がる心配がない。
また、様々な方向に屈曲させることができるので、図５及び図６に示すように、椅子４の座部４ａの周縁に取り付けられ、立ち上がったり座ったりする際に身体を支えるのに用いられる。 The cylindrical body 1 can be reliably gripped by inserting a fingertip into the cut line 3 and grasping with a palm. Since the reinforcing rib 2 is provided, the cylindrical body 1 has a cross section even when gripping and applying force. There is no worry of spreading greatly.
Further, since it is possible to bend in different directions, as shown in FIGS. 5 and 6, attached to the peripheral edge of the seat portion 4a of the chair 4, it is used to support the body when sitting or standing up .

そして、図７に示すように、筒体１を二重に重ねて互いに固定し、椅子４の座部４ａの外周縁に沿って、切れ目３が下を向くように配置する。
また、重ねた筒体１の外周面を座部４ａの上面から延びる表カバー５で被覆すると共に、内周面を椅子４の側面から立ち上がった裏カバー６で被覆する。このため、手触りがよく、外観も美しい。
さらに、表カバー５及び裏カバー６の端部は重ねた筒体１の間に挿入し、上に重ねた筒体１の内周面（平滑な面）に接着剤で固定する。
従って、表カバー５及び裏カバー６の端部は外部に露出せず、表カバー５と裏カバー６の端部どうしを縫い合わせる手間も省ける。
なお、この把持部材はベッドマットの周縁にも配置することができる。 Then, as shown in FIG. 7, superimposed tubular body 1 double secured together, along the outer edge of the seat portion 4a of the chair element 4, cuts 3 are arranged to face down.
Further, the outer peripheral surface of the stacked cylinder 1 is covered with a front cover 5 extending from the upper surface of the seat portion 4 a, and the inner peripheral surface is covered with a back cover 6 rising from the side surface of the chair 4. For this reason, it feels good and the appearance is beautiful.
Furthermore, the end portions of the front cover 5 and the back cover 6 are inserted between the stacked cylinders 1 and fixed to the inner peripheral surface (smooth surface) of the stacked cylinder 1 with an adhesive.
Therefore, the end portions of the front cover 5 and the back cover 6 are not exposed to the outside, and the labor of stitching the end portions of the front cover 5 and the back cover 6 together can be saved.
In addition, this holding member can also be arrange | positioned also at the periphery of a bed mat.
