Description

本発明は、椅子に座ってデスク作業を行う際に使用されるデスク作業補助具に関する。 The present invention relates to a desk work aid that is used when performing desk work while sitting on a chair.

これまでデスク作業に使用する椅子は、頭部、胸部の荷重を背もたれやヘッドレストによりスーパインで受けるものがほとんどである。
また、デスク作業時には、背もたれから体幹が離れるため、頭部、胸部の荷重は脊柱や骨盤にかかる。そのため、腰痛や肩こりが発生することがしばしばであった。
Until now, most chairs used for desk work have been designed to support the weight of the head and chest directly through the backrest and headrest.
In addition, when working at a desk, the torso is away from the backrest, so the weight of the head and chest is placed on the spine and pelvis, which often causes back pain and stiff shoulders.

社会の情報化が進み、また、勤務形態もテレワーク、ホームワークが推奨される近年は、家庭でのパソコン作業等のデスク作業が多くなっている。
特に、長時間にわたるパソコン作業等のデスク作業では、作業者の首・肩・腰への負担が大きくなり、腰痛や肩こり等の症例が多数発生している。
As society becomes more information-based and teleworking and homeworking are encouraged, the number of people doing desk work, such as working on a computer at home, has increased in recent years.
In particular, long hours of desk work, such as working on a computer, place a large strain on the worker's neck, shoulders, and lower back, resulting in many cases of lower back pain and stiff shoulders.

このような状況にあって、作業者の首・肩・腰への負担の軽減のため多数の提案がなされている。
例えば、特許文献1では、デスクに向かって着席した状態で作業を行う際に、腰に掛かる負担を軽減して良好な姿勢を保つことができるようにした、デスク作業用のクッションが提案されている。
In this situation, many proposals have been made to reduce the strain on the neck, shoulders, and lower back of workers.
For example, Patent Document 1 proposes a cushion for desk work that reduces the strain on the lower back and enables a person to maintain good posture when working while seated at a desk.

さらに、特許文献2では、デスク作業時における体への負担を回避するために、腹部、胸部、顎部までの前傾荷重を同時にサポートするようにしたデスク作業用のクッションが提案されている。 Furthermore, Patent Document 2 proposes a cushion for desk work that simultaneously supports forward loads on the abdomen, chest, and chin to avoid strain on the body during desk work.

これは、本体には腹部、胸部、顎までの前傾加重を同時にサポートするクッションを背面部に設け、使用者の頭部を置く顎乗せ部からの加重をデスクの天板上に乗せるだけで支えるアジャスターを設け、デスクの天板側面部への加重を受け止めるクッションを本体前面のアジャスター両脇に設け、断面が湾曲し且つ弾力性のある支柱を本体内部中央部に上下に亘り設けるものである。 The main body is equipped with cushions on the back that simultaneously support weight on the abdomen, chest, and chin when leaning forward, an adjuster is provided that supports weight from the chin rest where the user's head rests simply by placing it on the desk top, cushions are provided on both sides of the adjuster on the front of the main body to receive weight on the sides of the desk top, and elastic supports with curved cross sections are provided vertically in the center of the inside of the main body.

特許文献3では、卓上において使用するときに、上肢の疲労軽減に加えて、首、背及び腰などの疲労軽減に貢献できるデスク作業補助具が提案されている。
これは、卓上に置くことが可能で、かつ、置いた状態で前腕を載せることが可能な補助具本体と、上腕、肘及び前腕によって抱え込むことが可能で、かつ、補助具本体に着脱可能に接続することが可能なクッションとを備えるものである
Patent Document 3 proposes a desk work aid that, when used on a desk, can contribute to reducing fatigue in the neck, back, waist, etc. in addition to reducing fatigue in the upper limbs.
This device is equipped with an assisting device main body that can be placed on a table and on which the forearm can be placed while placed on the table, and a cushion that can be held by the upper arm, elbow and forearm and can be detachably connected to the assisting device main body.

特許文献1ないし3にあるようなデスク作業用のクッションあるいはクッションを伴うデスク作業補助具では、次のような問題点がある。
(1)デスクに固定されていないため、体のブレ等により作業中にデスク作業用のクッションあるいはクッションを伴うデスク作業補助具が外れたり、デスクから脱落することがある。
(2)作業者の体形に応じて形状を調整する機能がないため、クッションあるいはクッションを伴うデスク作業補助具がその目的を十分果たせない場合がある。
The cushions for desk work or desk work aids with cushions as described in Patent Documents 1 to 3 have the following problems.
(1) Because the cushion is not fixed to the desk, the cushion or the desk work aid with a cushion may become dislodged or fall off the desk while working due to body shaking or other reasons.
(2) Because there is no function for adjusting the shape according to the worker's body shape, the cushion or the desk work aid with a cushion may not fully serve its purpose.

本明細書における「デスク」は、机、学習机、作業机、ダイニングテーブル等を含めた広義の「デスク」を意味する。
また、「デスク作業」は、上記デスクでの長時間の事務、執筆、描画、読書、パソコン操作、精密操作等の作業を意味する。
In this specification, the term "desk" refers to a "desk" in a broad sense, including a desk, a study desk, a work desk, a dining table, and the like.
Additionally, "desk work" refers to work such as clerical work, writing, drawing, reading, operating a computer, precision operations, etc., performed at a desk for long periods of time.

(Example)
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A desk work auxiliary tool according to the present invention, which is used when performing desk work while sitting on a chair, will be described in detail below with reference to the drawings.
FIG. 1 is a side view of the desk work aid 1, and FIG. 2 is a front view thereof.
The desk work aid 1 according to the present invention comprises a fixing part 3 for fixing to a desk, a chest support part 4 and a chin support part 5.

デスクへの固定部3は、コの字状の金具12を有する。そして、コの字状の金具12をデスクの端部11の両端を挟むように取り付けることにより、デスクへの固定部3のデスク2への装着を行う。そして、コの字状の金具12に設けた固定レバーを締め付けることにより、デスクの端部11に完全に固定される。 The part 3 fixed to the desk has a U-shaped metal fitting 12. The part 3 fixed to the desk is attached to the desk 2 by attaching the U-shaped metal fitting 12 so that it sandwiches both ends of the end 11 of the desk. The part 3 is then completely fixed to the end 11 of the desk by tightening the fixing lever provided on the U-shaped metal fitting 12.

胸受部4は、デスクへの固定部3に連結されるとともに、作業者の左右の大胸筋部及び胸骨部を支持する胸受13と胸受保持調整機構14を有する。胸受保持調整機構14は、作業者の体形等に合うように胸受13の角度を調整する。
本実施例では、胸受保持調整機構14は、主支持材15、胸受を保持する胸受保持材16及び胸受角度調整材17で構成されている。
The chest support part 4 is connected to the fixed part 3 for the desk, and has a chest support 13 for supporting the left and right pectoral muscles and sternum of the worker, and a chest support adjustment mechanism 14. The chest support adjustment mechanism 14 adjusts the angle of the chest support 13 to suit the body shape, etc. of the worker.
In this embodiment, the chest support holding and adjustment mechanism 14 is composed of a main support material 15, a chest support holding material 16 that holds the chest support, and a chest support angle adjustment material 17.

主支持材15、胸受を保持する胸受保持材16及び胸受角度調整材17は、図1から分かるように、蝶番で結合されている。胸受角度調整材17には、長穴を開けた金属のプレート18が結合しており、調整後にノブボルト19で締め付けることにより胸受13の角度の調整を行う。 As can be seen from Figure 1, the main support member 15, the chest support holding member 16 that holds the chest support, and the chest support angle adjustment member 17 are connected with hinges. A metal plate 18 with a long hole is connected to the chest support angle adjustment member 17, and the angle of the chest support 13 is adjusted by tightening the knob bolt 19 after adjustment.

顎受部5は、胸受部4に連結されるとともに、作業者の頭部を支持する顎受20と顎受保持調整機構21を有する。顎受保持調整機構21は、図1から分かるように、作業者の頭部の体形に合うように顎受20の高さ及び角度を調整する。
本実施例では、顎受20の高さの調整は、顎受保持調整機構21の下部に長穴をあけておいて、調整後ノブボルト22で締め付けることにより行っている。
The chin rest 5 is connected to the chest rest 4 and has a chin rest 20 that supports the head of the operator, and a chin rest adjustment mechanism 21. As can be seen from Figure 1, the chin rest adjustment mechanism 21 adjusts the height and angle of the chin rest 20 so that it fits the shape of the operator's head.
In this embodiment, the height of the chin rest 20 is adjusted by drilling an oblong hole in the lower part of the chin rest holding adjustment mechanism 21 and tightening the knob bolt 22 after adjustment.

図2は、本発明に係るデスク作業補助具の正面図である。
顎受20は、クッション材で構成され、作業者の頭部を支持する。
胸受13は、クッション材で構成され、図1、図2から分かるように、その左右の部分Aは、作業者の大胸筋を支持するため盛り上がっている。また、中央下部Bは、作業者の胸骨を支持する。
FIG. 2 is a front view of the desk work aid according to the present invention.
The chin rest 20 is made of a cushioning material and supports the head of the operator.
The chest support 13 is made of a cushioning material, and as can be seen from Figures 1 and 2, the left and right portions A are raised to support the pectoral muscles of the worker, while the central lower portion B supports the sternum of the worker.

図3は、本発明に係るデスク作業補助具の使用状態を示す図面である。
作業者は、椅子に座ってパソコンを用いたデスク作業を行っている。
本発明に係るデスク作業補助具では、胸受は、作業者の左右の大胸筋部及び胸骨部を支持し、顎受は、作業者の頭部を支持している。すなわち、デスク作業者は、上体を胸受けに預け、頭の重さは顎受で支えることができる。
このため、パソコン作業等のデスク作業によるデスク作業者の首・肩・腰への負担が大幅に軽減される。
FIG. 3 is a diagram showing a state in which the desk work aid according to the present invention is used.
The worker is sitting in a chair and working at a desk using a computer.
In the desk work auxiliary tool according to the present invention, the chest support supports the left and right pectoral muscles and sternum of the worker, and the chin support supports the head of the worker. In other words, the desk worker can rest his or her upper body on the chest support and support the weight of the head with the chin support.
This significantly reduces the strain on the neck, shoulders, and back of desk workers when working at a computer or other desk jobs.
