Description

緩衝部材及びウェアラブル機器Buffer member and wearable device
　本発明は、ウェアラブル機器に取付けられて人体との間に介在させて使用する緩衝部材と、これを備えるウェアラブル機器に関する。 The present invention relates to a shock-absorbing member that is attached to a wearable device and is interposed between a human body and a wearable device including the same.
　腕時計、歩数計、医療機器など、人体に装着して使用する電子機器は従来から存在するが、近年では、こうした従来の機能に限られず、脈拍計測や位置計測、個人認証等々、様々な機能を発揮する電子機器として、またはスマートフォンと組合せた端末としてウェアラブル機器が開発されている。その一例として腕に装着して脈拍を計測し健康を管理する脈拍計に関する技術が特開２００１－１４９３２６号公報（特許文献１）に記載されている。 Electronic devices such as wristwatches, pedometers, and medical devices that have been worn on the human body have existed in the past, but in recent years they are not limited to these conventional functions, and various functions such as pulse measurement, position measurement, personal authentication, etc. Wearable devices have been developed as electronic devices to be exhibited or as terminals combined with smartphones. As an example, Japanese Patent Application Laid-Open No. 2001-149326 (Patent Document 1) describes a technique relating to a pulse meter that is worn on the arm and measures a pulse to manage health.
特開２００１－１４９３２６号公報JP 2001-149326 A
　こうしたウェアラブル機器には、生体情報を検出するセンサや、ウェアラブル機器の姿勢や位置や状態を検出するセンサが搭載されており、正しく装着することで適切な計測が行われるが、装着ズレや環境変化による外乱により、誤計測されることがある。例えば血液中のヘモグロビンが吸収する光量変化を光源と受光素子とを用いて測定し、脈拍を計測する脈拍計については、血管と機器との相対位置の相違による測定値の変化が課題となっている。 Such wearable devices are equipped with sensors that detect biological information and sensors that detect the posture, position, and state of the wearable device, so that proper measurement is performed by wearing them correctly. May be measured incorrectly due to disturbance caused by For example, for a pulse meter that measures changes in the amount of light absorbed by hemoglobin in blood using a light source and a light receiving element and measures the pulse, changes in the measured value due to the difference in relative position between the blood vessel and the device are an issue. Yes.
　上記課題に対して、ウェアラブル機器を人体に強く押し当てて固定すれば、装着ズレの影響を抑制することができる。しかし、腕を過剰に締め付ければ血流が妨げられ、また痛みを伴うことから装着性の観点での課題が残る。 ¡If the wearable device is firmly pressed against the human body to fix the above problem, it is possible to suppress the effect of wearing deviation. However, if the arm is tightened excessively, blood flow is hindered and painful, so there remains a problem in terms of wearability.
　以上のような従来技術を背景になされたのが本発明である。その目的は、ウェアラブル機器の装着ズレを抑制しつつ装着感を改善することにある。 The present invention has been made against the background of the above-described conventional technology. The purpose is to improve the wearing feeling while suppressing wearing deviation of the wearable device.
　上記目的を達成すべく本発明は以下のように構成される。 In order to achieve the above object, the present invention is configured as follows.
　本発明は、ウェアラブル機器に取付けられて人体との間に介在する緩衝部材について、人体との当接面側に位置し、内部に緩衝材が充填されており人体に触れて追従変形する環状で袋状の被覆部を有する緩衝部と、ウェアラブル機器への装着面側に位置し、前記袋状の被覆部を閉塞する蓋部とを備えることを特徴とする。 The present invention relates to a cushioning member that is attached to a wearable device and is interposed between the human body and an annular body that is located on the contact surface side with the human body and that is filled with a cushioning material and touches the human body to follow and deform. It is provided with the buffer part which has a bag-shaped coating | coated part, and the cover part which is located in the mounting surface side to a wearable apparatus, and obstruct | occludes the said bag-shaped coating | coated part.
　緩衝部材は、人体との当接面側に位置し、内部に緩衝材が充填されており人体に触れて追従変形する環状で袋状の被覆部を有する緩衝部を備えるため、ウェアラブル機器を人体に装着するだけで、緩衝部材が皮膚の表面に軽く押し当たり、装着者ごとや装着部位ごとに装着部位の大きさ、形状が異なっていても、緩衝部が柔らかく押し当たり追従変形することで隙間なく装着することができる。したがって、装着者が動いても、ウェアラブル機器の装着ズレが生じ難く、柔軟な緩衝部が軽く押し当たるだけであることから装着感も良い。 The cushioning member is located on the contact surface side with the human body, and includes a buffering portion having an annular bag-shaped covering portion that is filled with a cushioning material and touches the human body to follow and deforms the wearable device. Even if the cushioning member is lightly pressed against the surface of the skin and the size or shape of the mounting part is different for each wearer or mounting part, the buffering part softly presses and deforms following the gap. Can be installed without. Therefore, even when the wearer moves, the wearable device is not likely to be misaligned, and the flexible cushioning portion is only lightly pressed, so that the wearing feeling is good.
　緩衝部材をウェアラブル機器に装着し、ウェアラブル機器と人体の間に介在させても、緩衝部材は被覆部が環状であり、その内周側の内側空間は被覆部と人体とウェアラブル機器とで包囲された空間であるため、ウェアラブル機器に備わるセンサと皮膚表面との間を遮るものがなく、センサと皮膚表面との距離を一定に保つことができる。そのため、人体を動かすことによってウェアラブル機器が動き、皮膚表面とセンサとの距離が変化することによるセンサの誤計測を無くし正確な計測結果が得られる。 Even if the cushioning member is attached to the wearable device and is interposed between the wearable device and the human body, the cushioning member has an annular covering portion, and the inner space on the inner peripheral side is surrounded by the covering portion, the human body, and the wearable device. Therefore, there is no obstacle between the sensor and the skin surface provided in the wearable device, and the distance between the sensor and the skin surface can be kept constant. Therefore, the wearable device moves by moving the human body, and the erroneous measurement of the sensor due to the change in the distance between the skin surface and the sensor is eliminated, and an accurate measurement result can be obtained.
　さらに、緩衝部材が環状であることから、ウェアラブル機器の電子部品を収容する本体部の外縁形状に沿うように緩衝部材を取付けることができる。これによりウェアラブル機器の本体部の外縁側が緩衝部材を介して人体に固定されるため、ウェアラブル機器を安定した装着姿勢で人体に装着できる。よって、圧力センサであればセンサを誤動作させる衝撃、温度センサであれば外気の侵入、振動センサであれば外部振動を抑え、そして光センサであればセンサと皮膚表面との隙間の増減に起因した外光の検知量の相違によるノイズを少なくすることができる。このように外部要因（外乱）を抑えてウェアラブル機器の正確な働きを担保することができる。 Furthermore, since the buffer member is annular, the buffer member can be attached so as to follow the outer edge shape of the main body that accommodates the electronic parts of the wearable device. Thereby, since the outer edge side of the main-body part of a wearable apparatus is fixed to a human body via a buffer member, a wearable apparatus can be mounted | worn with a human body with the stable mounting | wearing attitude | position. Therefore, if it is a pressure sensor, it will be caused by an impact that causes the sensor to malfunction, if it is a temperature sensor, the intrusion of outside air, if it is a vibration sensor, it suppresses external vibration, and if it is a light sensor, it results from an increase or decrease in the gap between the sensor and the skin surface Noise due to a difference in the amount of detected external light can be reduced. In this way, external factors (disturbances) can be suppressed to ensure the correct functioning of the wearable device.
　本発明の緩衝部は、人体に触れて追従変形する環状で袋状の被覆部の内部に緩衝材を充填したものである。このように緩衝材と被覆部とを分けて構成することで、緩衝材を柔らかくして装着性を高める一方で、人体と接触する被覆部をそれよりも硬くして耐久性を高めることができる。 The shock-absorbing part of the present invention is one in which a shock-absorbing material is filled inside an annular bag-shaped covering part that touches and deforms following a human body. By separately configuring the cushioning material and the covering portion in this way, the cushioning material can be softened to improve the wearability, while the covering portion that comes into contact with the human body can be made harder and more durable. .
　本発明の緩衝部材は、ウェアラブル機器への装着面側に位置して袋状の被覆部を閉塞する蓋部を備える。蓋部がウェアラブル機器への装着面側に位置するので、人体との当接面側の緩衝部を柔らかくて快適な装着性を実現しつつ、人体に触れないウェアラブル機器の装着面側に対しては蓋部によって確実にウェアラブル機器に固定することができる。そのような蓋部は、ウェアラブル機器の装着面への取付時の取扱性を良好なものとするために、容易に折れ曲がらない形状保持性を有する樹脂フィルム、樹脂成形体、ゴム状弾性体等により形成することができる。 The shock-absorbing member of the present invention includes a lid portion that is located on the mounting surface side of the wearable device and closes the bag-shaped covering portion. Since the lid is located on the wearable device's mounting surface side, the cushioning portion on the contact surface side with the human body is soft and comfortable, and the wearable device does not touch the human body. Can be securely fixed to the wearable device by the lid. Such a lid portion is made of a resin film, a resin molded body, a rubber-like elastic body, etc. having a shape-retaining property that does not easily bend in order to improve the handleability when mounted on the mounting surface of the wearable device. Can be formed.
　本発明の緩衝部材を装着するウェアラブル機器としては、脈拍センサ等のセンサを備える活動量計やセンサを備えない腕時計であってもよく、機器の種類を限定するものではない。また、そうしたウェアラブル機器の人体への装着部位は、ウェアラブル機器のタイプに応じて手首、上腕、足首、頭部、胸部等、特に限定されるものではなく、どのタイプであっても装着部位に応じて装着ズレと快適な装着感を実現することが可能である。 The wearable device to which the shock-absorbing member of the present invention is attached may be an activity meter equipped with a sensor such as a pulse sensor or a wristwatch equipped with no sensor, and the kind of device is not limited. In addition, the wearing part of such a wearable device on the human body is not particularly limited according to the type of the wearable device, such as wrist, upper arm, ankle, head, chest, etc. It is possible to realize a comfortable wearing feeling with a displacement.
　前記本発明は、緩衝部又は蓋部の少なくとも何れかに、環状の緩衝部の内周側の内側空間と外周側の外部とを通気する透湿部を備えることができる。このため発汗の影響で湿度が上昇して結露したり汗が溜まったりし易い環状の緩衝部の前記内側空間を、透湿部を通じて外部（外気）に通気することができ、発汗による湿気を外部に逃がし、結露や汗による不快感を低減することができる。 In the present invention, at least one of the buffer portion and the lid portion may include a moisture permeable portion that ventilates the inner space on the inner peripheral side of the annular buffer portion and the outside on the outer peripheral side. For this reason, the inside space of the ring-shaped buffer part, where the humidity rises due to the effect of perspiration and condensation or sweat can easily accumulate, can be ventilated to the outside (outside air) through the moisture permeable part. This can reduce discomfort caused by condensation and sweat.
　前記本発明の緩衝部及び蓋部は、遮光性とすることができる。即ち、緩衝部及び蓋部を遮光性材質で形成することにより、緩衝部材を介してウェアラブル機器と人体とを密着させた際に、緩衝部材の緩衝部の内周側の内側空間に外部からの光が入射すること防ぐことができる。したがって光源と受光素子を有する脈拍計等の測定機能を有するウェアラブル機器では、外光の入射を防いで誤入力の無い正確な測定が可能となる。 The buffer portion and the lid portion of the present invention can be light-shielding. That is, by forming the buffer portion and the lid portion from a light-shielding material, when the wearable device and the human body are brought into close contact with each other via the buffer member, the inner space on the inner peripheral side of the buffer portion of the buffer member is exposed from the outside. Light can be prevented from entering. Therefore, in a wearable device having a measurement function such as a pulse meter having a light source and a light receiving element, it is possible to prevent the incidence of external light and perform an accurate measurement without erroneous input.
　前記本発明の緩衝部をなす緩衝材は、ゲル状物質又は多孔質体とすることができる。これによれば人体への追従変形に優れ装着性の高い緩衝部が得られる。 The buffer material constituting the buffer part of the present invention may be a gel material or a porous material. According to this, it is possible to obtain a buffer portion that is excellent in follow-up deformation to the human body and has high wearability.
　前記本発明の緩衝部をなす被覆部は、弾性薄膜とすることができる。これによれば緩衝材とともに人体への追従変形に優れる高い装着性を実現することができるとともに、耐久性も実現することができる。 The covering portion forming the buffer portion of the present invention can be an elastic thin film. According to this, it is possible to realize high wearability excellent in follow-up deformation to the human body together with the cushioning material, and it is also possible to realize durability.
　前記本発明の透湿部は、透湿性部材で形成した透湿層とすることができる。これによれば透湿性部材により形成される透湿層を通じて通気させることができる。また、透湿層として機能する薄膜状の透湿性部材を積層することで、緩衝部材に透湿部を簡単に設けることができる。また、こうした透湿層は通気させることができる一方で光の透過を防止することができるため、簡単に遮光することができる。 The moisture permeable portion of the present invention can be a moisture permeable layer formed of a moisture permeable member. According to this, it can be made to ventilate through the moisture-permeable layer formed of a moisture-permeable member. Moreover, a moisture-permeable part can be easily provided in a buffer member by laminating | stacking the thin film-like moisture-permeable member which functions as a moisture-permeable layer. Moreover, since such a moisture-permeable layer can be made to ventilate while preventing the transmission of light, it can be easily shielded from light.
　前記透湿性部材は、蓋部に貼り付けた透湿性シートとすることができる。また、前記透湿性部材は、緩衝部の被覆部を形成する透湿性シートとすることができる。 The moisture-permeable member can be a moisture-permeable sheet attached to the lid. The moisture permeable member may be a moisture permeable sheet that forms a covering portion of the buffer portion.
　前記本発明の透湿部は、透孔とすることができる。これによれば透湿性部材を準備する必要がなく透湿部を実現できる。また、単位体積あたりの通気量を高めることができるため、緩衝部材全体における透湿部の体積を小さくすることができ、透湿部を設けることによる柔軟性に対する影響を小さくすることができる。 The moisture permeable portion of the present invention can be a through hole. According to this, it is not necessary to prepare a moisture-permeable member, and a moisture-permeable part can be realized. Moreover, since the ventilation | gas_flowing amount per unit volume can be raised, the volume of the moisture permeable part in the whole buffer member can be made small, and the influence with respect to the softness | flexibility by providing a moisture permeable part can be made small.
　本発明は、前記目的を達成すべく、ウェアラブル機器の電子部品を収容する本体部と、本体部を保持するとともに人体に装着する外装部材とを備えるウェアラブル機器について、本体部又は外装部材における人体との当接面側に、前記緩衝部材を備えることを特徴とする。 In order to achieve the above object, the present invention relates to a wearable device including a main body portion that accommodates electronic parts of a wearable device and an exterior member that holds the main body portion and is attached to the human body. The buffer member is provided on the abutting surface side.
　このウェアラブル機器によれば、緩衝部材が人体と追従変形して柔らかく接触することで、ウェアラブル機器の人体に対する装着姿勢が安定して保持されるため、使用時の装着ズレを抑制しつつ快適な装着性を実現することができる。 According to this wearable device, since the cushioning member follows and deforms softly with the human body, the wearing posture of the wearable device with respect to the human body is stably maintained. Can be realized.
　前記本発明の外装部材は、緩衝部材の前記蓋部として前記被覆部を閉塞する。したがってウェアラブル機器の外装部材が蓋部として機能するため、外装部材に対して緩衝部材を一体の構造体として形成することができる。よって、緩衝部材をウェアラブル機器に対して後付けする必要がない。 The exterior member of the present invention closes the covering portion as the lid portion of the buffer member. Therefore, since the exterior member of the wearable device functions as a lid, the buffer member can be formed as an integral structure with respect to the exterior member. Therefore, it is not necessary to retrofit the cushioning member to the wearable device.
　本発明の緩衝部材及びこれを備えるウェアラブル機器によれば、人体に対するウェアラブル機器の装着ズレを抑制しつつ快適な装着感を得ることができる。したがって、センサを備えるウェアラブル機器については、誤計測を防止して確実な測定結果を得ることができる。 According to the cushioning member of the present invention and the wearable device including the cushioning member, it is possible to obtain a comfortable wearing feeling while suppressing the wearing deviation of the wearable device with respect to the human body. Therefore, a wearable device including a sensor can prevent erroneous measurement and obtain a reliable measurement result.

　以下、本発明の実施形態について図面を参照しつつ説明する。なお、各実施形態で共通する部材については、同一の符号を付して重複説明を省略する。また、共通する材質、作用、効果、製造方法等についても重複説明を省略する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, about the member which is common in each embodiment, the same code | symbol is attached | subjected and duplication description is abbreviate | omitted. Also, duplicate descriptions of common materials, functions, effects, manufacturing methods, and the like are omitted.
第１実施形態〔図１～図５〕First Embodiment [FIGS. 1 to 5]
構造：　緩衝部材１１は、例えば図１や図２で示すようなブレスレット型のウェアラブル機器１に取付けて使用される。ここで一実施形態として例示するウェアラブル機器１は、腕時計のように手首に巻いて装着されるもので、筐体に電子部品を内蔵する本体部２と、バンド部３とで構成されている。本体部２には、外部から視認可能な情報表示部２ａが設けられており、時刻や生体情報等の各種情報を表示することができる。情報表示部２ａの反対側にある本体部２の裏面部２ｂは平坦面として形成されており、ここに緩衝部材１１が取付けられる。また、本体部２にはセンサ２ｃが内蔵されており、裏面部２ｂにはセンサ２ｃを露出する透明な開口窓部が形成されている。 Structure : The buffer member 11 is used by being attached to a bracelet-type wearable device 1 as shown in FIGS. 1 and 2, for example. Here, the wearable device 1 illustrated as an embodiment is mounted by being wound around a wrist like a wristwatch, and is composed of a main body portion 2 in which an electronic component is built in a housing and a band portion 3. The main body part 2 is provided with an information display part 2a that can be visually recognized from the outside, and can display various information such as time and biological information. The back surface portion 2b of the main body portion 2 on the opposite side of the information display portion 2a is formed as a flat surface, to which the buffer member 11 is attached. The main body 2 has a built-in sensor 2c, and a transparent opening window that exposes the sensor 2c is formed on the back surface 2b.
　緩衝部材１１の平面形状は、図３（Ａ）で示すように環状に形成されている。その厚み方向における一方面はウェアラブル機器１の本体部２の裏面部２ｂへの装着面ｒ１となり、他方面は人体２と接触する当接面ｒ２となる。したがって、人体への装着時には、図４で示すように、ウェアラブル機器１と人体の装着箇所Ｓとの間に緩衝部材１１を介在させて、ウェアラブル機器１を人体の装着箇所Ｓに密着させることができる。緩衝部材１１の断面形状は、図３（Ｂ）で示すように、人体に触れる当接面ｒ２の側に凸となる半円状に形成するのが一態様である。 The planar shape of the buffer member 11 is formed in an annular shape as shown in FIG. One surface in the thickness direction is a mounting surface r1 to the back surface 2b of the main body 2 of the wearable device 1, and the other surface is a contact surface r2 that contacts the human body 2. Therefore, at the time of wearing on the human body, as shown in FIG. 4, the wearable device 1 may be brought into close contact with the wearing place S of the human body by interposing the buffer member 11 between the wearable device 1 and the wearing place S of the human body. it can. As shown in FIG. 3B, the cross-sectional shape of the buffer member 11 is formed in a semicircular shape that is convex toward the contact surface r2 that touches the human body.
　図５には、図３（Ｂ）の領域Ｒに相当する部位の部分拡大断面図を示す。この図５では、第１実施形態の緩衝部材１１のうち、その一態様である緩衝部材１１ａを示している。緩衝部材１１ａは、人体２への当接面ｒ２側に位置する緩衝部１２と、ウェアラブル機器１への装着面ｒ１側に位置するベース部１３とを備えている。 FIG. 5 shows a partially enlarged cross-sectional view of a portion corresponding to the region R in FIG. In this FIG. 5, the buffer member 11a which is the one aspect | mode is shown among the buffer members 11 of 1st Embodiment. The buffer member 11 a includes a buffer portion 12 located on the contact surface r <b> 2 side to the human body 2, and a base portion 13 located on the wear surface r <b> 1 side to the wearable device 1.
　緩衝部１２は、人体に触れて人体の装着箇所Ｓに合わせて追従変形する柔軟性を有する。緩衝部１２は、「緩衝材」としての芯部１４と、この芯部１４を包みこむとともに外皮を形成する被覆部１５とを有している。このように芯部１４と被覆部１５とを分けることで、同一硬度の単一素材で構成した場合と比較して、外観部品としての耐久性と、柔軟性とを高い次元で両立させることができる。 The buffer part 12 has the flexibility of touching the human body and following and deforming in accordance with the mounting location S of the human body. The buffer portion 12 includes a core portion 14 as a “buffer material” and a covering portion 15 that encloses the core portion 14 and forms an outer skin. By separating the core portion 14 and the covering portion 15 in this way, it is possible to achieve both high durability and flexibility as appearance parts, compared to a case where the core portion 14 and the covering portion 15 are made of the same material. it can.
　緩衝部１２は、上記柔軟性を有するため、人体に当てればその表面の起伏に追従変形して密着する。したがって、装着者が動いても、ウェアラブル機器１の装着ズレが生じ難く、柔軟な緩衝部１２が軽く押し当たるだけであることから装着感も良い。こうした性質を有するためには、日本工業規格であるＪＩＳ　Ｋ　６２５３に規定されるＥ硬度が０以上３０以下とすることが好ましい。また、アメリカ材料試験協会で採用されているＡＳＴＭＤ２２４０に規定されるＯＯ硬度が０を超えることが好ましい。ＯＯ硬度が０以下の場合は、外観部品としての耐久性が不十分となるおそれがあり、Ｅ硬度が３０を超える場合は、硬すぎて人体の起伏に追従させるためには強く押し当る必要があり装着感が損なわれるおそれがある。なお、Ｅ硬度３０はＯＯ硬度でおおよそ５５程度である。 Since the buffer portion 12 has the above-described flexibility, when it is applied to a human body, the buffer portion 12 is deformed following the undulations of the surface thereof and closely contacts. Therefore, even when the wearer moves, the wearable device 1 is not likely to be misaligned, and the flexible cushioning portion 12 is only lightly pressed, so that a feeling of wearing is good. In order to have such properties, it is preferable that the E hardness specified in JIS K 6253, which is the Japanese Industrial Standard, be 0 or more and 30 or less. Moreover, it is preferable that OO hardness prescribed | regulated to ASTMD2240 employ | adopted by the American material test association exceeds 0. If the OO hardness is 0 or less, the durability as an appearance part may be insufficient. If the E hardness exceeds 30, it is too hard to be pressed hard to follow the undulations of the human body. There is a possibility that wearing feeling is impaired. The E hardness 30 is about 55 in terms of OO hardness.
　芯部１４は、緩衝部１２において前述したウェアラブル機器１の装着ズレを防ぎ、快適な装着感を生じさせる柔軟性を担う主部であり、緩衝部１２の硬さを規定する部分ともなっている。芯部１４のＥ硬度は、Ｅ２６以下であることが好ましい。Ｅ２６以下とすることで心地よい装着性が得られるためである。硬さの下限としてはＯＯ硬度でＯＯ０を超えることが好ましい。ＯＯ０以下であると耐久性が不十分となるおそれがある。 The core portion 14 is a main portion that bears the flexibility that prevents the wearable device 1 described above from being worn out in the buffer portion 12 and generates a comfortable wearing feeling, and is also a portion that defines the hardness of the buffer portion 12. The E hardness of the core portion 14 is preferably E26 or less. This is because comfortability can be obtained by setting E26 or less. The lower limit of the hardness is preferably greater than OO0 in terms of OO hardness. If it is OO0 or less, the durability may be insufficient.
　そのような芯部１４には、シリコーンゲル等のゲル状物質、ウレタンスポンジのような多孔質体を用いることができるが、ゲル状物質を用いることが好ましい。多孔質体に比べて圧縮永久歪の値が低く、長期間の使用であってもへたり難いためである。また、これらの材質は固形状であり液状ではないため、被覆部１５が仮に破れることがあっても内容物が外に飛び散ることがない。 Such a core portion 14 can be made of a gel material such as silicone gel or a porous material such as urethane sponge, but it is preferable to use a gel material. This is because the value of compression set is lower than that of the porous body, and it is difficult to sag even after long-term use. In addition, since these materials are solid and not liquid, the contents do not scatter outside even if the cover 15 is torn.
　被覆部１５は、緩衝部材１１の外観を構成するとともに、その内部には芯部１４が充填されて、これを収容しつつ覆う保護層として機能する。そのため、薄くても耐久性のある材質が好ましく、芯部１４ほど柔軟である必要はないが、薄膜の状態で容易に変形する程度の柔軟性を有していることが好ましい。具体的には、熱硬化性ゴムや熱可塑性エラストマーを用いることができる。また、被覆部１５の硬度は、下限は前記Ｅ硬度で３０を超え、上限は同様にＪＩＳ　Ｋ　６２５３に規定されるＡ硬度で８０以下であることが好ましい。Ｅ硬度が３０以下の場合は、耐久性が不十分となるおそれがある。一方、Ａ硬度が８０を超える場合は、薄膜であっても硬すぎて装着感が損なわれるおそれがある。また、柔軟なゲルで構成した芯部１４を被覆する場合には、ブリードアウト抑止層としても機能する。特にブリードアウトを抑制する必要がある場合には前記ゲルに含まれる可塑剤等のオイルが含浸し難い材質を用いることが好ましい。 The covering portion 15 constitutes the external appearance of the buffer member 11, and the core portion 14 is filled therein and functions as a protective layer that covers and accommodates the core portion 14. Therefore, a material that is durable even if it is thin is preferable, and it is not necessary to be as flexible as the core portion 14, but it is preferable that the material is flexible enough to be easily deformed in a thin film state. Specifically, thermosetting rubber or thermoplastic elastomer can be used. Further, the hardness of the covering portion 15 is preferably such that the lower limit exceeds 30 in terms of E hardness and the upper limit is similarly 80 or less in terms of A hardness as defined in JIS K 6253. When the E hardness is 30 or less, the durability may be insufficient. On the other hand, when the A hardness exceeds 80, even a thin film is too hard and the wearing feeling may be impaired. Moreover, when coat | covering the core part 14 comprised with the soft gel, it functions also as a bleed-out suppression layer. In particular, when it is necessary to suppress bleed out, it is preferable to use a material that is difficult to be impregnated with oil such as a plasticizer contained in the gel.
　ベース部１３は、ウェアラブル機器１に対する装着面ｒ１を有し、緩衝部１２を保持しつつウェアラブル機器１に対して固着する部位である。ベース部１３は、蓋部１６と、ウェアラブル機器１の本体部２の裏面部２ｂに固定する接着部１７とを有している。 The base portion 13 has a mounting surface r1 for the wearable device 1 and is a portion that is fixed to the wearable device 1 while holding the buffer portion 12. The base portion 13 includes a lid portion 16 and an adhesive portion 17 that is fixed to the back surface portion 2 b of the main body portion 2 of the wearable device 1.
　蓋部１６は、環状であり、被覆部１５とともに芯部１４を密封する部位であり、図５で示すように、被覆部１５のフランジ部１５ａと固着している。蓋部１６が被覆部１５と固着して芯部１４を密封することで、芯部１４を構成する柔らかい緩衝材が外部に漏れ出さないようにしている。 The lid portion 16 is annular and is a portion that seals the core portion 14 together with the covering portion 15, and is fixed to the flange portion 15 a of the covering portion 15 as shown in FIG. 5. The lid portion 16 is fixed to the covering portion 15 to seal the core portion 14 so that the soft cushioning material constituting the core portion 14 does not leak to the outside.
　蓋部１６に用いる材質は、被覆部１５と同じものを用いることができるが、その他に硬質樹脂でなるフィルム等とすることができる。蓋部１６は人体２に当接しないため、被覆部１５のような柔軟性は必須ではなく、蓋部１６によって確実にウェアラブル機器１に固定することができることが重要である。そのような蓋部１６は、ウェアラブル機器１の裏面部２ｂへの取付時の取扱性を良好なものとするために、容易に折れ曲がらない形状保持性を有する樹脂フィルム、樹脂成形体、ゴム状弾性体等により形成することができる。 The material used for the lid portion 16 can be the same as that of the covering portion 15, but can also be a film made of a hard resin. Since the lid portion 16 does not contact the human body 2, flexibility like the covering portion 15 is not essential, and it is important that the lid portion 16 can be reliably fixed to the wearable device 1. Such a lid 16 has a resin film, a resin molded body, and a rubber-like shape having shape retaining properties that do not easily bend in order to improve the handleability when attached to the back surface 2b of the wearable device 1. It can be formed of an elastic body or the like.
　接着部１７は、緩衝部材１１をウェアラブル機器１へ接着させる粘着剤層を備えるものである。粘着剤層を形成する材質は特に限定せず、粘着剤、接着剤、ホットメルト材料などを用いることができるが、緩衝部材１１ａの製造の容易性から両面粘着テープを用いることが好ましい。 The adhesive portion 17 includes an adhesive layer that adheres the buffer member 11 to the wearable device 1. The material for forming the pressure-sensitive adhesive layer is not particularly limited, and a pressure-sensitive adhesive, an adhesive, a hot melt material, or the like can be used. However, it is preferable to use a double-sided pressure-sensitive adhesive tape from the viewpoint of ease of manufacturing the buffer member 11a.
製造方法：　以上のような緩衝部材１１を製造するには、被覆部１５を成形し、その容器状の内部に芯部１４となる液状組成物を注入してから、それを硬化させてゲル状の芯部１４とする。次に、蓋部１６を被覆部１５のフランジ部１５ａに載せて、接着剤による接着等の固着手段により被覆部１５に蓋部１６を固着することで芯部１４を密封する。さらに接着部１７となる両面粘着テープ等を蓋部１６に積層して緩衝部材１１ａを得ることができる。 Manufacturing method : In order to manufacture the buffer member 11 as described above, the covering portion 15 is molded, and after the liquid composition to be the core portion 14 is injected into the container shape, the liquid composition is cured and gelled. The core part 14 is used. Next, the lid part 16 is placed on the flange part 15a of the covering part 15, and the core part 14 is sealed by fixing the lid part 16 to the covering part 15 by fixing means such as bonding with an adhesive. Furthermore, the buffer member 11a can be obtained by laminating a double-sided pressure-sensitive adhesive tape or the like serving as the adhesive portion 17 on the lid portion 16.
作用・効果：　本実施形態の緩衝部材１１及びこれを備えるウェアラブル機器１によれば、装着者が動いても、ウェアラブル機器１の装着ズレが生じ難く、柔軟な緩衝部１２が軽く押し当たるだけであることから優れた装着感を実現することができる。 Action / Effect : According to the buffer member 11 and the wearable device 1 having the same according to the present embodiment, even when the wearer moves, the wearable device 1 is less likely to be worn out, and the flexible buffer portion 12 is merely pressed lightly. Because of this, it is possible to achieve an excellent wearing feeling.
　緩衝部材１１は、ウェアラブル機器１と人体の間に介在させても被覆部１５が環状であり、その内側空間は被覆部１５と人体とウェアラブル機器１とで包囲された空間であるため、ウェアラブル機器１に備わるセンサ２ｃと皮膚表面との間を遮るものがなく、センサ２ｃと皮膚表面との距離を一定に保つことができる。そのため、人体を動かすことによってウェアラブル機器１が動き、皮膚表面とセンサ２ｃとの距離が変化することによるセンサ２ｃの誤計測を無くし正確な計測結果が得られる。 Even if the buffer member 11 is interposed between the wearable device 1 and the human body, the covering portion 15 has an annular shape, and its inner space is a space surrounded by the covering portion 15, the human body, and the wearable device 1. 1 is not obstructed between the sensor 2c and the skin surface, and the distance between the sensor 2c and the skin surface can be kept constant. Therefore, the wearable device 1 moves by moving the human body, and an erroneous measurement of the sensor 2c due to a change in the distance between the skin surface and the sensor 2c is eliminated, and an accurate measurement result is obtained.
　緩衝部材１１が環状であることから、ウェアラブル機器１の本体部２の裏面部２ｂの外縁形状に沿うように緩衝部材１１を取付けることができる。これによりウェアラブル機器１の本体部２の裏面部２ｂの外縁側が緩衝部材１１を土台として人体に固定されるため、ウェアラブル機器１を安定した装着姿勢で人体に装着することができる。 Since the buffer member 11 is annular, the buffer member 11 can be attached along the outer edge shape of the back surface 2b of the main body 2 of the wearable device 1. Thereby, since the outer edge side of the back surface 2b of the main body 2 of the wearable device 1 is fixed to the human body with the buffer member 11 as a base, the wearable device 1 can be mounted on the human body in a stable mounting posture.
第１実施形態の第１変形例First modification of the first embodiment
　第１実施形態による緩衝部材１１ａの構成部材は、遮光性の材質で形成することができる。遮光性とすることで緩衝部材１１ａの内周側の内側空間への外光の侵入を防ぐことができる。ウェアラブル機器１に搭載するセンサ２ｃが、光センサ２ｃである場合、緩衝部材１１ａを遮光性とすることで、外部からの光を光センサ２ｃが拾うことを防止して、光センサ２ｃの誤計測を防止することができる。 The constituent members of the buffer member 11a according to the first embodiment can be formed of a light-shielding material. By making it light-shielding, it is possible to prevent external light from entering the inner space on the inner peripheral side of the buffer member 11a. When the sensor 2c mounted on the wearable device 1 is the optical sensor 2c, the buffer member 11a is made light-shielding to prevent the optical sensor 2c from picking up light from the outside, and erroneous measurement of the optical sensor 2c. Can be prevented.
第１実施形態の第２変形例〔図６〕Second Modification of First Embodiment [FIG. 6]
　第１実施形態の緩衝部材１１の第２変形例としての緩衝部材１１ｂを図６に示す。緩衝部材１１ｂは、例えば図６で示すように、ウェアラブル機器１と人体の装着箇所Ｓと環状の緩衝部材１１とで閉塞された緩衝部材１１の内周側の内側空間と、緩衝部材１１の外周側の外部とを通気させる「透湿部」としてシート状の透湿性部材１９ａで形成した透湿層を設けたものである。 FIG. 6 shows a buffer member 11b as a second modification of the buffer member 11 of the first embodiment. For example, as shown in FIG. 6, the buffer member 11 b includes an inner space on the inner peripheral side of the buffer member 11 that is closed by the wearable device 1, the mounting portion S of the human body, and the annular buffer member 11, and the outer periphery of the buffer member 11. A moisture permeable layer formed of a sheet-like moisture permeable member 19a is provided as a “moisture permeable portion” for venting the outside of the side.
　シート状の透湿性部材１９ａは、この変形例では接着部１７と蓋部１６との間に設けている。透湿性部材１９ａは、平面視では緩衝部材１１の全体にわたって環状に形成することが好ましく、蓋部１６に積層して取付ける。緩衝部材１１の全周に亘って透湿性を発揮するためである。また、その材質としては、連続気泡の多孔質体、不織布、メッシュシート、微細な気孔を備えた透湿フィルムや、その他の透湿フィルムを用いることができる。 The sheet-like moisture-permeable member 19a is provided between the bonding portion 17 and the lid portion 16 in this modification. The moisture-permeable member 19a is preferably formed in an annular shape over the entire cushioning member 11 in a plan view, and is laminated and attached to the lid portion 16. This is because moisture permeability is exhibited over the entire circumference of the buffer member 11. In addition, as the material thereof, an open-cell porous body, a nonwoven fabric, a mesh sheet, a moisture-permeable film having fine pores, and other moisture-permeable films can be used.
　透湿性部材１９ａを備えない態様とすると、発汗の影響で緩衝部材１１の内側空間の湿度が上昇して結露したり、汗そのものが溜まったりして不快となることがある。したがって透湿性部材１９ａを設けることで、緩衝部材１１の前記内側空間と外部との通気性を確保し、湿気を外部に逃がし、汗や結露による不快感を低減することができる。 If the moisture permeable member 19a is not provided, the humidity in the inner space of the buffer member 11 may increase due to the effect of perspiration and condensation may occur, or the sweat itself may accumulate and become uncomfortable. Therefore, by providing the moisture permeable member 19a, the air permeability between the inner space of the buffer member 11 and the outside can be secured, moisture can be released to the outside, and uncomfortable feeling due to sweat or condensation can be reduced.
　シート状の透湿性部材１９ａは、上記の材質の中でも特にメッシュシートを用いることが好ましい。メッシュシートを用いれば、メッシュを構成する繊維間の空間を介して緩衝部材１１の内側空間と外部との通気性を確保できるとともに、汗が繊維を伝わって内側空間から外部に流れるため、効率よく汗を逃がすことができるからである。このため、特に発汗の多い場合であっても、汗や結露による不快感を低減することができる。こうしたメッシュシートは、繊維が緩衝部材１１の内側空間から緩衝部材１１の外部まで延びるように構成されたものを用いることが好ましい。 The sheet-like moisture-permeable member 19a is preferably a mesh sheet among the above materials. If the mesh sheet is used, air permeability between the inner space of the cushioning member 11 and the outside can be ensured through the space between the fibers constituting the mesh, and sweat can flow from the inner space to the outside through the fibers, so that it can be efficiently performed. This is because sweat can be released. For this reason, even when there is a lot of sweating, discomfort due to sweat and condensation can be reduced. It is preferable to use such a mesh sheet configured such that the fibers extend from the inner space of the buffer member 11 to the outside of the buffer member 11.
第１実施形態の第３変形例〔図７〕Third Modification of First Embodiment [FIG. 7]
　緩衝部材１１の別の態様としての緩衝部材１１ｃを図７に示す。先の態様で示した緩衝部材１１ｂでは、透湿部としての透湿性部材１９ａをベース部１３である接着部１７と蓋部１６との間に設けていたが、この変形例では透湿性部材１９ｂを緩衝部１２に設けている。 7 shows a buffer member 11c as another mode of the buffer member 11. As shown in FIG. In the buffer member 11b shown in the previous embodiment, the moisture permeable member 19a as the moisture permeable portion is provided between the adhesive portion 17 as the base portion 13 and the lid portion 16, but in this modification, the moisture permeable member 19b is provided. Is provided in the buffer section 12.
　緩衝部材１１ｃを形成するには、透湿性部材１９ｂを挟んだ両側に位置する緩衝部１２をそれぞれ形成する。ベース部１２側に位置する部位は、透湿性部材１９ｂを積層できる形状に形成した被覆部１５に芯部１４を注入して蓋部１６で封入して得る。また、反対側に位置する緩衝部１２は、所定の形状にした被覆部１５に芯部１４を注入し、被覆部１５と同じ材質で固着して芯部１４を封入する。こうして得た２つの部材の間に透湿性部材１９ｂを積層して相互に固着する。そして蓋部１６には、接着部１７を積層する。最後に緩衝部１２が半円状になるようにバリになる部分は切除して緩衝部材１１ｂを得る。この変形例２による緩衝部材１１ｃでも緩衝部材１１ｂと同様に環状の内外の通気性をもたせることができる。 In order to form the buffer member 11c, the buffer portions 12 located on both sides of the moisture permeable member 19b are formed. The part located on the base part 12 side is obtained by injecting the core part 14 into the covering part 15 formed in a shape capable of laminating the moisture permeable member 19 b and sealing with the lid part 16. Further, the buffer portion 12 located on the opposite side injects the core portion 14 into the covering portion 15 having a predetermined shape, and is fixed with the same material as the covering portion 15 to enclose the core portion 14. The moisture permeable member 19b is laminated between the two members thus obtained and fixed to each other. Then, the adhesive portion 17 is laminated on the lid portion 16. Finally, the portion that becomes a burr is cut so that the buffer portion 12 is semicircular to obtain the buffer member 11b. The buffer member 11c according to the modified example 2 can also have an annular inner and outer air permeability like the buffer member 11b.
第１実施形態の第４変形例〔図８〕Fourth Modification of First Embodiment [FIG. 8]
　第４変形例の緩衝部材１１ｄを図８に示す。先の変形例で示した緩衝部材１１ｂ，１１ｃでは、透湿部としての透湿性部材１９ａ，１９ｂを緩衝部材１１ｂ，１１ｃの独立した構成部位として設けていたが、第４変形例で示す緩衝部材１１ｄでは、被覆部１５自体を透湿性部材により形成して、被覆部１５が「透湿部」を兼ねた透湿層として機能させる構成としている。 FIG. 8 shows a buffer member 11d of the fourth modification. In the buffer members 11b and 11c shown in the previous modification, the moisture- permeable members 19a and 19b as moisture-permeable portions are provided as independent components of the buffer members 11b and 11c, but the buffer members shown in the fourth modification In 11d, the covering portion 15 itself is formed of a moisture-permeable member so that the covering portion 15 functions as a moisture-permeable layer that also functions as a “moisture-permeable portion”.
　そのような透湿性を有する被覆部１５に用いることができる材質としては、連続気泡の多孔質体、不織布、微細な気孔を備えた透湿フィルム、多孔質体を薄膜で挟みこんだ積層フィルムや無孔質透湿フィルム、その他の透湿フィルムであって、硬さの下限がＥ硬度で３０を超え、上限がＡ硬度で８０以下であるものを用いることができる。Ｅ硬度が３０以下の場合は、耐久性が不十分となるおそれがある。一方、Ａ硬度が８０を超える場合は、薄膜であっても硬すぎてしまい、装着感が損なわれるおそれがある。 Examples of materials that can be used for the coating portion 15 having moisture permeability include an open-cell porous body, a nonwoven fabric, a moisture-permeable film having fine pores, a laminated film in which the porous body is sandwiched between thin films, A nonporous moisture permeable film or other moisture permeable film having a lower limit of hardness exceeding 30 in E hardness and an upper limit of 80 or less in A hardness can be used. When the E hardness is 30 or less, the durability may be insufficient. On the other hand, when the A hardness exceeds 80, even a thin film is too hard, and there is a possibility that the wearing feeling is impaired.
　連続気泡を有する多孔質材等を用いる場合に、人体２への当接面ｒ２となる被覆部１５の表面には連続気泡の開口部が無く、被覆部１５の端面上にこの開口部が表れることが好ましい。開口部が当接面ｒ２に表出すると、その開口に汗や異物が侵入することで、透湿性が損なわれるおそれがあるからである。被覆部１５の端面は環状の内側と外側に存在するため、端面に開口部があれば環状の内外の連通を図ることができる。 When using a porous material or the like having open cells, there is no open cell opening on the surface of the covering portion 15 that becomes the contact surface r2 to the human body 2, and this opening portion appears on the end surface of the covering portion 15. It is preferable. This is because when the opening is exposed on the contact surface r2, moisture permeability may be impaired due to permeation of sweat or foreign matter into the opening. Since the end surface of the covering portion 15 exists on the inner side and the outer side of the ring, if there is an opening on the end surface, communication between the ring inside and outside can be achieved.
第１実施形態の第５変形例〔図８〕Fifth Modification of First Embodiment [FIG. 8]
　第５変形例の緩衝部材１１ｅは、第４変形例において、その芯部１４を透湿性部材とすることで、被覆部１５とともに「透湿部」を兼ねる構成としたものである。こうした芯部１４の材質としては、好ましくは連続気泡の多孔質材（スポンジ等）が挙げられる。この多孔質材の硬さは、透湿手段としていない芯部１４と同様の硬さとすることが好ましく、Ｅ硬度でＥ２６以下である。第５変形例では、被覆部１５に加えて芯部１４もまた透湿性部材であるため、極めて高い透湿性を緩衝部材１１ｅに与えることができる。 In the fourth modification, the buffer member 11e of the fifth modification is configured to serve as a “moisture permeable part” together with the covering part 15 by using the core part 14 as a moisture permeable member. The material of the core part 14 is preferably an open-cell porous material (sponge or the like). The hardness of the porous material is preferably the same as that of the core 14 that is not used as a moisture permeable means, and the E hardness is E26 or less. In the fifth modified example, since the core portion 14 is also a moisture permeable member in addition to the covering portion 15, extremely high moisture permeability can be imparted to the buffer member 11e.
第１実施形態の第６変形例〔図５〕Sixth Modification of First Embodiment [FIG. 5]
　第６変形例の緩衝部材１１ｆは、第１実施形態の緩衝部材１１ａの蓋部１６を透湿性部材で形成したものである。蓋部１６を「透湿部」とする場合には、図６の第２変形例で示すような独立した透湿性部材１９ａを設ける必要はない。但し、こうした変形例が取り得るのは、芯部１４から可塑剤やオイルが滲み出さず、可塑剤やオイルによって蓋部１６の透湿性を損なうことが無い場合や、芯部１４を構成するゲル状部材自体が蓋部１６の透湿性を損なうおそれが無い場合である。 The buffer member 11f of the sixth modification is formed by forming the lid portion 16 of the buffer member 11a of the first embodiment with a moisture permeable member. When the lid portion 16 is a “moisture permeable portion”, it is not necessary to provide an independent moisture permeable member 19a as shown in the second modified example of FIG. However, such a modification can take the case where the plasticizer or oil does not ooze out from the core part 14 and the plasticizer or oil does not impair the moisture permeability of the lid part 16, or the gel constituting the core part 14. This is a case where the shaped member itself does not possibly impair the moisture permeability of the lid portion 16.
第１実施形態の第７変形例Seventh modification of the first embodiment
　第１実施形態の緩衝部材１１ａでは、その全周に亘って透湿性部材１９ａを設ける構成としたが、緩衝部材１１ａの内周面と外周面とを繋ぐ線状、帯状、円弧状に設けることもできる。このように透湿性部材１９を設けることで、透湿性部材１９を設けた部分以外の部分で装着面ｒ１側から当接面ｒ２側までが一体に固着され透湿性部材１９が剥がれ難い緩衝部材１１が得られる。 In the buffer member 11a of the first embodiment, the moisture permeable member 19a is provided over the entire circumference. However, the buffer member 11a is provided in a line shape, a strip shape, or an arc shape that connects the inner peripheral surface and the outer peripheral surface of the buffer member 11a. You can also. By providing the moisture-permeable member 19 in this way, the cushioning member 11 that is firmly fixed integrally from the mounting surface r1 side to the contact surface r2 side at a portion other than the portion where the moisture-permeable member 19 is provided, and the moisture-permeable member 19 is difficult to peel off. Is obtained.
第１実施形態の第８変形例〔図９〕Eighth Modification of First Embodiment [FIG. 9]
　第１実施形態の緩衝部材１１では透湿部として透湿性部材１９を設けたが、第８変形例の緩衝部材１１ｇでは「透湿部」として透孔２０ａを設けている。透孔２０ａは、ベース部１３の一部に形成されており、緩衝部材１１ｇの内周側の内側空間と外周側の外部と連通させるものである。透孔２０ａは、平面視では２本の直線を鈍角で繋がる非直線状に形成している。このように非直線状とすることで、緩衝部材１１ｇの外側から内側に外光が入り込むことを抑制することができる。 In the buffer member 11 of the first embodiment, the moisture permeable member 19 is provided as the moisture permeable portion, but in the buffer member 11g of the eighth modified example, the through hole 20a is provided as the “moisture permeable portion”. The through hole 20a is formed in a part of the base portion 13, and communicates with the inner space on the inner peripheral side of the buffer member 11g and the outer side on the outer peripheral side. The through hole 20a is formed in a non-linear shape that connects two straight lines at an obtuse angle in plan view. Thus, by making it non-linear, it can suppress that external light enters into the inner side from the outer side of the buffer member 11g.
　透孔２０ａは、蓋部１６における接着部１７側の表面に凹溝を形成しておき、凹溝以外の蓋部１６の平坦面に接着層１７を積層することで形成することができる。蓋部１６の材質としては、第１実施形態で説明した材質を用いることができるが、ここではＡ硬度が８０以上の材質を用いることが好ましい。緩衝部材１１ｇを圧縮したときに透孔２０ａが閉塞しないようにするためである。 The through hole 20a can be formed by forming a concave groove on the surface of the lid portion 16 on the side of the adhesive portion 17 and laminating the adhesive layer 17 on the flat surface of the lid portion 16 other than the concave groove. As the material of the lid portion 16, the material described in the first embodiment can be used, but here, it is preferable to use a material having an A hardness of 80 or more. This is to prevent the through hole 20a from being closed when the buffer member 11g is compressed.
第１実施形態の第９変形例〔図１０〕Ninth Modification of First Embodiment [FIG. 10]
　第１実施形態の第９変形例の緩衝部材１１ｈを図１０に示す。第８変形例の緩衝部材１１ｇでは、透孔２０ａをベース部１３である蓋部１３と接着部１７との間に設けていたが、緩衝部材１１ｈでは、緩衝部１２に透孔２０ｂを設けたものである。透孔２０ｂの平面形状は、第８変形例の非直線状の透孔２０ａと同様である。緩衝部材１１ｈの透孔２０ｂは、緩衝部１２を形成する被覆部１５を成形する際に透孔２０ｂを形成する。緩衝部１２に透孔２０ｂを設けたため、蓋部１６に透孔２０ａを設ける場合よりも透孔２０ｂの長さを短くすることができ、通気性を高めることができる。 FIG. 10 shows a buffer member 11h according to a ninth modification of the first embodiment. In the buffer member 11g of the eighth modification, the through hole 20a is provided between the lid portion 13 which is the base portion 13 and the adhesive portion 17, but in the buffer member 11h, the through hole 20b is provided in the buffer portion 12. Is. The planar shape of the through hole 20b is the same as the non-linear through hole 20a of the eighth modification. The through hole 20b of the buffer member 11h forms the through hole 20b when the covering portion 15 that forms the buffer portion 12 is formed. Since the through-hole 20b is provided in the buffer part 12, the length of the through-hole 20b can be shortened compared with the case where the through-hole 20a is provided in the cover part 16, and air permeability can be improved.
第２実施形態〔図１１〕Second Embodiment [FIG. 11]
　第２実施形態の緩衝部材２１は、第１実施形態の接着部１７を取り除くとともに、第１実施形態の蓋部１６を、ウェアラブル機器１の本体部２の裏面部２ｂをなす蓋と兼用する蓋体２２として一体に形成したものである。したがって、被覆部１５は、そのフランジ部１５ａが蓋体２２に対して接着剤により固着されて芯材１４が密封されている。 The cushioning member 21 of the second embodiment removes the adhesive portion 17 of the first embodiment, and also uses the lid portion 16 of the first embodiment as a lid that forms the back surface portion 2b of the main body 2 of the wearable device 1. The body 22 is integrally formed. Therefore, the cover portion 15 has the flange portion 15 a fixed to the lid body 22 by an adhesive, and the core material 14 is sealed.
　このように緩衝部材２１の一部である蓋部２２をウェアラブル機器１の本体部２と共通させることで、緩衝部材２１をウェアラブル機器１の付属品とすることなく、緩衝部材２１を備えるウェアラブル機器１を提供することができる。また、緩衝部材２１を予め備えるウェアラブル機器１によれば、緩衝部材２１をウェアラブル機器１へ固着する際の位置ずれなどの装着ミスを防ぎ、ウェアラブル機器１がセンサを備える場合には所望の計測の確実性を高めることができる。また、ウェアラブル機器１の本体部２と緩衝部材２１を一体にすることによるデザイン性を高めることができる。 Thus, by making the cover part 22 which is a part of the buffer member 21 in common with the main body 2 of the wearable device 1, the wearable device including the buffer member 21 without the buffer member 21 being an accessory of the wearable device 1. 1 can be provided. In addition, according to the wearable device 1 provided with the buffer member 21 in advance, a mounting error such as a displacement when the buffer member 21 is fixed to the wearable device 1 is prevented, and when the wearable device 1 includes a sensor, a desired measurement can be performed. Certainty can be increased. Moreover, the design property by uniting the main-body part 2 and the buffer member 21 of the wearable apparatus 1 can be improved.
