Description

本発明は、操作部、操作レバー、及び事務用家具に関するものである。   The present invention relates to an operation unit, an operation lever, and office furniture.

事務用家具には、回転力によって反力、位置や姿勢などを調整する機構が設けられている。例えば、事務用椅子では、背もたれを後方へ傾斜させることができるリクライニング機能が設けられている。この事務用椅子は、背もたれを後方へ傾斜させる際の反力の強弱を調整できる調整機構を備えている(例えば、特許文献1)。当該特許文献1には、回転させることにより、背もたれを後方に傾斜させる際の反力を調整することができる操作レバーが開示されている。これにより、事務用椅子は、ユーザが自分の好みに応じ、上記反力を調整することによって、よりスムーズに背もたれを傾斜させることができる。   Office furniture is provided with a mechanism for adjusting reaction force, position, posture, and the like by rotational force. For example, an office chair is provided with a reclining function capable of tilting the backrest backward. This office chair includes an adjustment mechanism that can adjust the strength of reaction force when the backrest is tilted backward (for example, Patent Document 1).

しかしながら、従来の操作部においては、ユーザが力を十分に付与することができる形状ではなく、ユーザが余計な力をかける必要があった。また従来の操作部の場合、ユーザの力を効率的に受けとめるための構成を単純に付加すると、機械的強度が低下してしまう、という懸念があった。   However, in the conventional operation unit, the shape is not such that the user can sufficiently apply force, and the user has to apply extra force. Further, in the case of a conventional operation unit, there is a concern that the mechanical strength is lowered if a configuration for efficiently receiving the user's force is added.

本発明は、少ない力で回転力を付与することができると共に、機械的強度に優れる操作部、操作レバー、及び事務用椅子を提供することを目的とする。   An object of the present invention is to provide an operation unit, an operation lever, and an office chair that can apply a rotational force with a small force and are excellent in mechanical strength.

本発明に係る操作部は、レバー本体の一端に設けられる操作部において、前記レバー本体に連結される連結部と、把持部と、回転力受け部とを備えており、前記把持部と前記回転力受け部が、前記連結部の中心軸方向から見て、滑らかに一体形成されていることを特徴とする。   An operation unit according to the present invention is an operation unit provided at one end of a lever body, and includes a connection unit coupled to the lever body, a gripping unit, and a rotational force receiving unit. The force receiving portion is integrally formed smoothly when viewed from the central axis direction of the connecting portion.

本発明に係る操作レバーは、上記操作部と、レバー本体とを有することを特徴とする。   An operation lever according to the present invention includes the operation unit and a lever body.

本発明に係る事務用家具は、上記操作レバーが設けられたことを特徴とする。   The office furniture according to the present invention is characterized in that the operation lever is provided.

本発明によれば、操作部は、回転力受け部を備えることにより、容易に力を加えることができるので、少ない力で回転力を付与することができる。また、操作部は、把持部と回転力受け部が、連結部の中心軸方向から見て、滑らかに一体形成されていることから、従来のように応力が集中する形状を有しないので、機械的強度にも優れる。   According to the present invention, since the operation unit includes the rotational force receiving unit, it is possible to easily apply a force, so that the rotational force can be applied with a small force. In addition, since the gripping portion and the rotational force receiving portion are integrally formed smoothly when viewed from the central axis direction of the connecting portion, the operation portion does not have a shape in which stress is concentrated as in the related art. Excellent strength.

以下、図面を参照して本発明の実施形態について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1.実施形態
図1に示すように、事務用家具としての事務用椅子10は、脚部12と、座部14と、背もたれ16とを備える。脚部12は、下端に複数の足18を有する。足18の先端には、それぞれキャスタ20が取り付けられている。脚部12の上端には、前記座部14の高さを調整する調整機構(図示しない)を介して座部14が設けられている。座部14は、脚部12に支持された受台22と、受台22上に設けられる座クッション24とを有する。
1. Embodiment As shown in FIG. 1, an office chair 10 as office furniture includes a leg portion 12, a seat portion 14, and a backrest 16. The leg 12 has a plurality of legs 18 at the lower end. A caster 20 is attached to the tip of each foot 18. A seat portion 14 is provided at the upper end of the leg portion 12 via an adjustment mechanism (not shown) that adjusts the height of the seat portion 14. The seat part 14 includes a cradle 22 supported by the leg part 12 and a seat cushion 24 provided on the cradle 22.

背もたれ16は、後方へ傾斜させる際の反力の強弱を調整できる調整機構(図示しない)を介して、受台22に軸支されている。調整機構には、操作レバー26Aが設けられている。調整機構は、操作レバー26Aが一方向に回転することにより、背もたれ16を後方に傾斜させる際の反力を強くでき、逆方向へ回転することにより弱めることができるように形成されている。   The backrest 16 is pivotally supported by the cradle 22 via an adjustment mechanism (not shown) that can adjust the strength of the reaction force when tilting backward. The adjustment mechanism is provided with an operation lever 26A. The adjustment mechanism is formed so that the reaction force when tilting the backrest 16 backward can be increased by rotating the operation lever 26A in one direction and can be weakened by rotating in the reverse direction.

図2〜図5に示すように、操作レバー26Aは、調整機構に連結されたレバー本体28と、レバー本体28の一端に設けられた操作部30Aとを有する。レバー本体28は、金属製の棒状の部材で構成されている。操作部30Aは、前記レバー本体28に連結される連結部32と、把持部34Aと、回転力受け部36Aとを有する。   As shown in FIGS. 2 to 5, the operation lever 26 </ b> A includes a lever main body 28 coupled to the adjustment mechanism, and an operation unit 30 </ b> A provided at one end of the lever main body 28. The lever body 28 is made of a metal rod-like member. The operation unit 30A includes a connecting part 32 connected to the lever main body 28, a gripping part 34A, and a rotational force receiving part 36A.

操作部30Aは、樹脂製の筒状部材で構成されている。連結部32は、操作部30Aの一端に形成されており、先端へ行くにしたがってすり鉢状に窄まった形状を有し、その先端部分に形成された孔(図示しない)と、当該孔に挿入されたレバー本体28を固定する固定部(図示しない)とを備えている。操作部30Aは、連結部32においてレバー本体28の一端に連結されることにより、レバー本体28と一体的に回転し得る。   The operation unit 30A is made of a resin cylindrical member. The connecting portion 32 is formed at one end of the operation portion 30A, has a shape constricted in a mortar shape as it goes to the tip, and is inserted into the hole (not shown) formed in the tip portion. And a fixing portion (not shown) for fixing the lever main body 28. The operation portion 30 </ b> A can be rotated integrally with the lever main body 28 by being connected to one end of the lever main body 28 at the connecting portion 32.

操作部30Aの他端は、開放されており、前記連結部32の中心軸L方向から見て、把持部34Aと、半径方向に凸となる形状を有する回転力受け部36Aとの接続部分が滑らかに一体形成されている。ここでいう「滑らか」とは、中心軸Lを中心とした回転方向の力が加わった場合に応力が集中する形状、例えば中心軸Lに対し半径方向に鋭く凹んだ形状、を除く形状をいう。   The other end of the operation portion 30A is open, and a connection portion between the grip portion 34A and the rotational force receiving portion 36A having a shape that protrudes in the radial direction when viewed from the central axis L direction of the connecting portion 32 is provided. It is integrally formed smoothly. The term “smooth” as used herein refers to a shape excluding a shape in which stress is concentrated when a rotational force about the central axis L is applied, for example, a shape that is sharply recessed in the radial direction with respect to the central axis L. .

本実施形態の場合、操作部30Aは、液滴形状に形成されている。把持部34Aは前記中心軸L方向からみて、前記中心軸Lを中心とする円形状の一部で構成されている。把持部34Aの中心軸Lを中心とする円形状の中心角略90°に相当する部分に、回転力受け部36Aが一体に形成されている。回転力受け部36Aは、先端38が略90°で交わる一対の斜辺39で構成され、基端が滑らかに把持部34Aに接続されている。操作部30Aは、中心軸Lと回転力受け部36Aの先端とを結ぶ線に対し対称に形成されている。   In the case of this embodiment, the operation unit 30A is formed in a droplet shape. The grip portion 34A is formed of a part of a circle centered on the central axis L when viewed from the central axis L direction. A rotational force receiving portion 36A is integrally formed at a portion corresponding to a circular central angle of about 90 ° centered on the central axis L of the grip portion 34A. The rotational force receiving portion 36A is composed of a pair of hypotenuses 39 where the distal end 38 intersects at approximately 90 °, and the proximal end is smoothly connected to the gripping portion 34A. The operation portion 30A is formed symmetrically with respect to a line connecting the central axis L and the tip of the rotational force receiving portion 36A.

このように構成された操作部30Aは、中心軸L方向から見た形状が、半径方向に凹となる形状を含まず、膨んだ形状で形成されている。また操作部30Aは、中心軸L方向から見て、流線型である。   The operation unit 30A configured as described above is formed in a swelled shape, not including a shape that is concave in the radial direction, as viewed from the direction of the central axis L. The operation unit 30A is streamlined when viewed from the central axis L direction.

次に、上記のように構成された操作レバー26Aの作用及び効果について説明する。背もたれ16を後方に傾斜させる際の反力を強くしようとする際、ユーザが操作部30Aを把持し、当該操作部30Aを例えば一方向へ回転させる。これによりレバー本体28が操作部30Aと一体的に回転し、レバー本体28の回転力が調整機構に伝達される。調整機構は、伝達された回転力に応じて、上記反力を強める。また上記反力を弱めようとする際、ユーザが操作部30Aを把持し、当該操作部30Aを逆方向へ回転させる。これによりレバー本体28が操作部30Aと一体的に回転し、レバー本体28の回転力が調整機構に伝達される。調整機構は、伝達された回転力に応じて、上記反力を弱める。   Next, the operation and effect of the operation lever 26A configured as described above will be described. When trying to increase the reaction force when tilting the backrest 16 backward, the user holds the operation unit 30A and rotates the operation unit 30A in, for example, one direction. As a result, the lever main body 28 rotates integrally with the operation unit 30A, and the rotational force of the lever main body 28 is transmitted to the adjustment mechanism. The adjustment mechanism increases the reaction force according to the transmitted rotational force. When attempting to weaken the reaction force, the user grips the operation unit 30A and rotates the operation unit 30A in the reverse direction. As a result, the lever main body 28 rotates integrally with the operation unit 30A, and the rotational force of the lever main body 28 is transmitted to the adjustment mechanism. The adjustment mechanism weakens the reaction force according to the transmitted rotational force.

この際ユーザは、把持部34Aを主に一方の掌で包み込むようにして把持し、親指で回転力受け部36Aを押すようにして、操作部30Aを回転させる。このように操作部30Aは、回転力受け部36Aを備えることにより、容易に力を加えることができる。したがって操作部30Aは、少ない力で回転力を付与することができる。また、操作部30Aは、把持部34Aと回転力受け部36Aが、連結部32の中心軸L方向から見て、滑らかに一体形成されていることから、従来のように応力が集中する形状を有しないので、機械的強度にも優れる。このように操作部30Aは、少ない力で回転力を付与でき、機械的強度にも優れることから、小型化を実現することができる。   At this time, the user grips the grip part 34A mainly by wrapping it with one palm, and rotates the operation part 30A by pressing the rotational force receiving part 36A with the thumb. As described above, the operation unit 30 </ b> A can easily apply a force by including the rotational force receiving unit 36 </ b> A. Therefore, the operation unit 30A can apply the rotational force with a small force. Further, the operating portion 30A has a shape in which stress is concentrated as in the conventional case because the gripping portion 34A and the rotational force receiving portion 36A are integrally formed smoothly when viewed from the central axis L direction of the connecting portion 32. It does not have excellent mechanical strength. As described above, the operation unit 30A can apply a rotational force with a small force and is excellent in mechanical strength, and thus can be downsized.

操作部30Aは、液滴形状に形成されており、中心軸L方向から見て一方向に一対の斜辺で構成された回転力受け部36Aが設けられていることにより、ユーザが操作部30Aを中心軸L方向から見たり、回転力受け部36Aを手で触れたりすることにより、操作レバー26Aの回転位置を知覚することができる。したがって操作部30Aは、回転位置の知覚性を向上することができる。   The operation unit 30A is formed in a droplet shape, and is provided with a rotational force receiving unit 36A composed of a pair of hypotenuses in one direction when viewed from the central axis L direction, so that the user can operate the operation unit 30A. The rotational position of the operation lever 26A can be perceived by looking from the center axis L direction or by touching the rotational force receiving portion 36A with a hand. Therefore, the operation unit 30A can improve the perceptibility of the rotational position.

本実施形態の場合、操作部30Aは、中心軸L方向から見た形状が、凹となる形状を含まず、凸となる形状で形成されていることにより、機械的強度により優れる。   In the case of the present embodiment, the operation unit 30A is superior in mechanical strength because the shape viewed from the direction of the central axis L does not include a concave shape and is formed in a convex shape.
