Description
本発明は、寝具の寝返り性の評価方法に関する。 The present invention relates to a method for evaluating the overturnability of bedding.
従来、マットレス、敷き布団などの寝具の商品価値に関する評価基準の一つとして、寝返りのしやすさ（以下、寝返り性という）があり、この寝返り性を、寝具に模擬人体を仰臥させた状態から、この模擬人体をその一側部を基点として横臥する状態まで移動させるのに必要とされる引揚げ力を測定し、この引揚げ力を基にして寝具の寝返り性を評価することが提案されている（特許文献１参照）。 Conventionally, as one of the evaluation standards regarding the commercial value of bedding such as mattresses and mattresses, there is the ease of turning over (hereinafter referred to as turning over), and this turning over from the state where the simulated human body is laid on the bedding It has been proposed to measure the lifting force required to move the simulated human body to a state lying on its one side as a base point, and to evaluate the bedding of the bedding based on this lifting force. (See Patent Document 1).
前記従来の寝具の寝返り性の評価方法では、首、肩、腰などを除いた模擬人体を使用して引揚げ力を測定している。様々な寝具を相対的に評価する際には、この測定方法でも良い。 In the conventional method for evaluating the turnability of bedding, the lifting force is measured using a simulated human body excluding the neck, shoulders, and waist. This measurement method may be used when relatively evaluating various beddings.
しかし、実際に人が、寝具の上で寝返りをする際には、上体をひねってから下半身が追従する動きをしたり、肩やひじ等の凹凸部の抵抗があるため、これらが寝返り性を評価する際には重要である。そのため、首、肩、腰などを除き、可動部のない模擬人体で測定した引揚げ力と、寝具を購入・使用する人（以下において、被測定者という）を使用して測定した引揚げ力とでは差異が生じてしまう。 However, when a person rolls over on the bedding, the lower body moves after twisting the upper body, and there is resistance to uneven parts such as the shoulders and elbows. It is important when evaluating. Therefore, with the exception of the neck, shoulders, waist, etc., the lifting force measured with a simulated human body without moving parts, and the lifting force measured with a person who purchases and uses bedding (hereinafter referred to as the person being measured) Will cause a difference.
また、寝返り性を評価するうえで、被測定者の体重や体型も重要な要素であり、模擬人体と寝具を使用する人とで、体型や体重の差が大きいほど、被測定者と模擬人体の引揚げ力の差異は大きくなってしまう。 In addition, the body weight and body shape of the person being measured are important factors in evaluating the rollover ability.The greater the difference in body shape and body weight between the simulated human body and the person using the bedding, the greater the difference between the body and the body being measured. The difference in the lifting force will be large.
そして、顧客が実際に寝具に寝た際に感じる感覚と、模擬人体での引揚げ力を基にして得た寝返り性とで異なる結果が生じてしまう恐れがあり、店頭等で、模擬人体での引揚げ力に基づいて顧客にとって寝返り性のよい寝具として提案する際に問題となる恐れがある。 And, there is a risk of different results depending on the sense that the customer actually feels when sleeping on the bedding and the roll-over property obtained based on the lifting power in the simulated human body. When it is proposed as a bedding having a good roll-over property for a customer based on the lifting force, there is a risk of a problem.
また、前記従来の寝具の寝返り性の評価方法は、模擬人体の脇部に直接フックを取付け、このフックに引揚げ力測定器具を連結して、引揚げ力の測定を行う方法であるため、寝具を使用する人に直接フックを取り付けることは出来ず、前記従来の寝具の寝返り性の評価方法を、被測定者の測定に適用することはできなかった。 In addition, the conventional method for evaluating the rollover of the bedding is a method in which a hook is directly attached to the side portion of the simulated human body, and a lifting force measuring instrument is connected to the hook to measure the lifting force. A hook cannot be directly attached to a person who uses the bedding, and the conventional method for evaluating the turnability of the bedding cannot be applied to the measurement of the measurement subject.
そこで、本発明は、店頭等で容易に被測定者の寝具の寝返り性の評価を行うことができる評価方法を提供することを目的とするものである。 Therefore, an object of the present invention is to provide an evaluation method capable of easily evaluating the turnability of a person to be measured at a store or the like.
前記の課題を解決するために、請求項１記載の発明は、寝具に、一端に引揚げ力測定手段を接続する接続部を設けたシート状の敷部材を敷き、
該敷部材の少なくとも他端部の上部に被測定者の一方の腕の少なくとも一部が位置するように仰臥させ、
前記敷部材の接続部側を引揚げ、前記被測定者を、前記被測定者の一方の腕側を基点として、仰臥の状態から横臥する状態まで移動させるのに必要とされる引揚げ力を前記引揚げ力測定手段で測定し、
この引揚げ力を基に、前記寝具の寝返り性を評価することを特徴とするものである。
In order to solve the above-mentioned problem, the invention according to claim 1 lays a sheet-like laying member provided with a connection part for connecting a lifting force measuring means at one end to the bedding,
The laying member is supine so that at least a part of one arm of the person to be measured is located on the upper part of at least the other end of the laying member,
The lifting force required to lift the connecting portion side of the laying member and move the measured person from the supine position to the lying position with one arm side of the measured person as a base point. Measured by the lifting force measuring means,
On the basis of this lifting force, the rollover property of the bedding is evaluated.
請求項２記載の発明は、請求項１記載の発明において、前記敷部材は、被測定者の下半身には位置しないことを特徴とするものである。 According to a second aspect of the present invention, in the first aspect of the present invention, the laying member is not positioned on the lower body of the measurement subject.
本発明によれば、同一の敷部材を用い、その敷部材に被測定者を仰臥させて引揚げ力を測定するので、被測定者自身の引揚げ力を得ることが出来、その測定値を基にして寝返り性を評価し、被測定者に最適な寝具を提案することが出来る。 According to the present invention, since the same laying member is used and the person to be measured is laid on the laying member and the lifting force is measured, the lifting force of the person to be measured can be obtained, and the measured value is obtained. Based on the evaluation, it is possible to evaluate the rolling ability and propose the optimal bedding for the person to be measured.
また、同一の敷部材を用いて、その敷部材に被測定者を仰臥させて引揚げ力の測定を行うため、被測定者の体重や身長に係らず、かつ、どのような寝具でも、被測定者の寝返り性に関する測定を行うことが出来るとともに、被測定者の負担が少なく、かつ、迅速に測定することが出来る。 In addition, since the same laying member is used and the person to be measured is laid on the laying member and the lifting force is measured, regardless of the weight and height of the person to be measured, any bedding can be used. It is possible to perform measurement relating to the rolling ability of the measurer, and to perform measurement quickly and with less burden on the subject.
本発明を実施するための形態を図に示す実施例に基づいて説明する。
［実施例１］
図１は、本発明係る寝具の寝返り性の評価方法に用いる実施例１の可撓性のあるシート状の敷部材を示すもので、この敷部材１について説明する。
A mode for carrying out the present invention will be described based on an embodiment shown in the drawings.
[Example 1]
FIG. 1 shows a flexible sheet-like laying member of Example 1 used in the method for evaluating the bedding of a bedding according to the present invention. The laying member 1 will be described.
敷部材１は、図１〜５に示すように、シート状に形成され、敷部材１は、その表面の摩擦係数が高く、伸縮率の低い部材で構成することが好ましく、例えば、麻、綿、タオル地で構成された布帛、帆布、伸縮率の低いゴム、皮などを用いることが出来る。一方、表面の摩擦係数の低い絹やビニールなどや、伸縮率の大きなニットや編み物などは用いないことが好ましい。また、敷部材１の厚みは、任意に設定することが出来る。 The laying member 1 is formed in a sheet shape as shown in FIGS. 1 to 5, and the laying member 1 is preferably composed of a member having a high friction coefficient on its surface and a low expansion / contraction rate, for example, hemp, cotton Cloth made of towel cloth, canvas, rubber having a low stretch rate, leather, etc. can be used. On the other hand, it is preferable not to use silk, vinyl, or the like having a low friction coefficient on the surface, or knit or knitted fabric having a large expansion / contraction rate. Moreover, the thickness of the covering member 1 can be set arbitrarily.
敷部材１は、図１に示すように、その本体部１ａが長方形状に形成され、本体部１ａの長手方向（横方向）の一端部には、両側が先部ほど縮径するテーパ状に形成された縮径部１ｂが形成されている。縮径部１ｂの先部には、引揚げ力測定手段２を接続する接続部３が、敷部材１の表裏方向に回動可能に設けられている。 As shown in FIG. 1, the laying member 1 has a main body 1 a formed in a rectangular shape, and has a taper shape in which one end of the main body 1 a in the longitudinal direction (lateral direction) is reduced in diameter toward the tip. The formed reduced diameter portion 1b is formed. A connecting portion 3 for connecting the lifting force measuring means 2 is provided at the tip of the reduced diameter portion 1b so as to be rotatable in the front and back direction of the floor member 1.
敷部材１は、図１に示すように、その本体部１ａの長手方向（横方向）の幅Ｌ１が、被測定者１１の肩幅より大きく、短手方向（縦方向）の長さＬ２は、肩から背中部、すなわち、肋骨部を覆う大きさで、臀部（腰部）から下方の下半身は覆わない大きさに設定されている。 As shown in FIG. 1, the laying member 1 has a width L1 in the longitudinal direction (lateral direction) of the main body 1a larger than the shoulder width of the person to be measured 11, and a length L2 in the short direction (longitudinal direction) The size is set to cover the shoulder to the back, that is, the rib, and not to cover the lower body below the buttocks (waist).
接続部３としては、後述する引揚げ力測定手段２を取外し可能に連結することが出来れば、任意の形状のものを用いることが出来るが、本実施例では、図１に示すように、リング状の金具を用いた。このリング状の金具の一部を、縮径部１ｂの先部を丸めて形成した連結部１ｃに回動可能に挿通して設けられている。 As the connection portion 3, any shape can be used as long as the lifting force measuring means 2, which will be described later, can be detachably connected. In this embodiment, as shown in FIG. A metal fitting was used. A part of the ring-shaped metal fitting is rotatably inserted into a connecting portion 1c formed by rounding the tip of the reduced diameter portion 1b.
引揚げ力を測定する引揚げ力測定手段２としては、引揚げ力を測定することが出来れば任意の測定器具を用いることが出来、好ましくは、フォースゲージを用い、本実施例では、フォースゲージの一種であるプッシュプルゲージを用いた。 As the lifting force measuring means 2 for measuring the lifting force, any measuring instrument can be used as long as the lifting force can be measured. Preferably, a force gauge is used, and in this embodiment, the force gauge is used. A push-pull gauge is used.
次に、引揚げ力の測定方法について説明する。
先ず、敷部材１を、寝具１０の上面に、図１に示すように、寝具１０の左右方向に敷部材１の長手方向が位置する、すなわち、寝具１０の左右方向に接続部３が位置するように載置する。
Next, a method for measuring the lifting force will be described.
First, as shown in FIG. 1, the longitudinal direction of the laying member 1 is positioned on the upper surface of the bedding 10 in the left-right direction of the bedding 10, that is, the connecting portion 3 is positioned in the left-right direction of the bedding 10. To be placed.
次に、図２に示すように、被測定者１１が、その身長方向が寝具１０の縦方向となるとともに、被測定者１１の両腕１１ａ，１１ｂを、その胴の両側部に位置し、かつ、その一方の腕１１ａが、敷部材１の長手方向の他端部の上部に位置するようにして仰臥する。また、敷部材１は、その短手方向の一端１ｄが、被測定者１１の肩ラインに位置するようにし、敷部材１の短手方向の他端１ｅは、臀部から下方の下半身には位置しないようすることが好ましい。 Next, as shown in FIG. 2, the person to be measured 11 has a height direction that is the vertical direction of the bedding 10, and the arms 11 a and 11 b of the person to be measured 11 are positioned on both sides of the torso, And the one arm 11a is supine so that it may be located in the upper part of the other end part of the longitudinal direction of the covering member 1. FIG. The laying member 1 has one end 1d in the short direction positioned on the shoulder line of the person to be measured 11, and the other end 1e in the short direction of the laying member 1 is positioned on the lower half of the body below the buttocks. It is preferable not to do so.
次に、図３に示すように、接続部３に対し、引揚げ力測定手段２を、直接若しくは、所定以上の強度を有し、伸縮性の少ない接続具を介して連結する。 Next, as shown in FIG. 3, the lifting force measuring means 2 is connected to the connection portion 3 directly or via a connection tool having a predetermined strength or more and less stretchability.
次に、図３〜５に示すように、被測定者１１を、一方の腕１１ａを基点として、図３の仰臥状態から、図５の横臥状態となるまで、敷部材１の本体部１ａを、寝具１０の上面に対する一定の引揚げ角度（本実施例では４５°）で、かつ、一定の速度で引揚げる。この引揚げ時において、被測定者１１の一方の腕１１ａにより抑えられている本体部１ａが、その部位と寝具１０との間の摩擦力により、その部位が固定端となって敷部材１の他端部の寝具１０に対する移動が抑制され、敷部材１による被測定者の横臥状態への寝返りを行うことが出来る。 Next, as shown in FIGS. 3 to 5, the body 11 a of the laying member 1 is moved from the supine state of FIG. 3 to the recumbent state of FIG. It is lifted at a constant lifting angle (45 ° in this embodiment) with respect to the upper surface of the bedding 10 and at a constant speed. At the time of lifting, the body portion 1a held down by one arm 11a of the person to be measured 11 becomes a fixed end by the frictional force between the portion and the bedding 10, and the portion of the laying member 1 becomes the fixed end. The movement of the other end with respect to the bedding 10 is suppressed, and the person to be measured can be turned over to the lying state by the floor member 1.
なお、敷部材１の一端部を引揚げる際に、敷部材１と寝具１０との間の摩擦力が低いと、敷部材１の長手方向の他端部が寝具１０に対して移動し、また、敷部材１が伸縮して変形してしまうと、引揚げ力の測定に影響するため、敷部材１は、その表面の摩擦係数が高く、伸縮率の低い部材を用いることが好ましい。 When the one end portion of the laying member 1 is lifted, if the frictional force between the laying member 1 and the bedding 10 is low, the other end portion of the laying member 1 in the longitudinal direction moves relative to the bedding 10, and If the laying member 1 expands and contracts, it affects the measurement of the lifting force. Therefore, the laying member 1 is preferably a member having a high surface friction coefficient and a low expansion rate.
店頭等において、寝具１０としてマットレスを用いて測定する場合には、基準マットレスを用いて行う。本実施例では、この基本マットレスとして、複数の伸縮性を有する樹脂製の線条が、立体的で不規則に絡まって部分的に融着されて、一体化した立体網状構造体からなり、反発力が７５ｇ／ｃｍ２のものを用いた。この基準マットレスは、出願人の社外数百人にモニターしたところ９０％の人が寝心地が良いと回答したものである。 When measurement is performed using a mattress as the bedding 10 at a storefront or the like, the measurement is performed using a reference mattress. In this embodiment, as the basic mattress, a plurality of stretchable resin filaments are three-dimensionally irregularly entangled and partially fused together to form an integrated three-dimensional network structure. A force having a force of 75 g / cm 2 was used. This standard mattress was monitored by hundreds of outside applicants, and 90% of the respondents answered that they were comfortable.
上記の方法で、被測定者１１を引揚げて引揚げ力を経時的に測定することで、図６に示すようなグラフを得ることが出来る。図６に示すグラフＡが、基準マットレスでの測定結果の一例で、グラフＢは、基準マットレスとは素材と硬さが異なる市販のマットレスを同じ被測定者１１で測定した測定結果である。 A graph as shown in FIG. 6 can be obtained by lifting the person to be measured 11 and measuring the lifting force over time by the above method. A graph A shown in FIG. 6 is an example of a measurement result with a reference mattress, and a graph B is a measurement result obtained by measuring a commercially available mattress having a hardness different from that of the reference mattress with the same person 11 to be measured.
図６に示すグラフＡ，Ｂのように、マットレスの硬さや材質により、引揚げ力の最大値、積算値、立ち上がり角度等が異なることが分かる。これらの値を基にして、被測定者１１に係る寝具の寝返り性を評価することが出来る。 As shown in graphs A and B shown in FIG. 6, it can be seen that the maximum value, integrated value, rising angle, and the like of the lifting force differ depending on the hardness and material of the mattress. Based on these values, it is possible to evaluate the turnability of the bedding associated with the person under measurement 11.
また、基準マットレスを用いて、体重、身長を例えば、５ｋｇ、５ｃｍの幅で、夫々の範囲内にある被測定者１１を測定し、各標準偏差を導き出しておく。店頭等で、基準マットレスを用いて、上記方法で顧客の引揚げ力の測定を行い、その顧客のデータと標準偏差との違いや、基準マットレスに対する顧客の感覚等を基にして、その顧客に最適なマットレスの提案を行うことができ、顧客の満足度を高いものとすることが期待できる。 In addition, using the reference mattress, the measurement subject 11 is measured within a range of 5 kg and 5 cm in weight and height, for example, and each standard deviation is derived. At the store, etc., using the standard mattress, measure the customer's lifting force by the above method, and based on the difference between the customer's data and standard deviation, the customer's sense of the standard mattress, etc. It is possible to propose an optimal mattress and to expect high customer satisfaction.
例えば、標準偏差より、顧客の引揚げ力の最大値、積算値などが高ければ、この顧客は寝返りの際に強い力を必要としていると推察できるため、基準マットレスよりも硬めのマットレスを提案する。また、標準偏差より、顧客の引揚げ力の最大値、積算値などが低ければ、この顧客は寝返りを、比較的弱い力で行うことが出来ると推察できるため、基準マットレスよりも柔らかめのマットレスを提案することができる。また、必要であれば、選んだマットレスで顧客の引揚げ力を再度測定して、標準偏差と比較を行っても良い。 For example, if the customer's maximum lifting force or integrated value is higher than the standard deviation, it can be inferred that this customer needs a strong force when turning over, so a mattress that is harder than the standard mattress is proposed. . In addition, if the customer's maximum lifting force, integrated value, etc. are lower than the standard deviation, it can be assumed that the customer can turn over with a relatively weak force, so the mattress is softer than the standard mattress. Can be proposed. If necessary, the customer's lifting force may be measured again with the selected mattress and compared with the standard deviation.
本発明の寝具の寝返り性の測定に際し、同一の敷部材１を用い、この敷部材１を寝具の上に載置し、その上に被測定者１１が仰臥することのみで対応することが出来るために、様々な体型の被測定者１１、種類の異なる寝具にも即座に容易に対応し、寝返り性を測定することが出来る。また、測定に際しての被測定者１１への負担も少ない。 In the measurement of the turnability of the bedding of the present invention, the same laying member 1 is used, and this laying member 1 is placed on the bedding, and the person to be measured 11 lies on his / her back. Therefore, it is possible to immediately and easily cope with the person to be measured 11 of various body types and different types of bedding, and to measure the turnability. In addition, the burden on the measurement subject 11 during measurement is small.
また、人が寝返りをする際には、腰から上の上半身を寝返り方向に動かした後に、腰から下の下半身が追従して寝返りを行う。一方、敷部材１を、被測定者１１の肩から背中部に位置し、臀部から下の下半身は覆わないようにしたことにより、敷部材１の一端を引揚げると、被測定者１１の敷部材１が位置する上半身が先ず動き、その後に下半身が追従するようになるため、実際の寝返りに近い動きとなり、測定される寝返り性に関する数値が、実際の寝返りの動きに即した値とすることができる。 Also, when a person rolls over, the upper body from the waist moves in the turn direction, and then the lower body from the waist follows and rolls over. On the other hand, the covering member 1 is positioned from the shoulder of the person to be measured 11 to the back, and the lower body below the buttocks is not covered. Since the upper body where the member 1 is located first moves and the lower body follows thereafter, the movement is close to the actual rollover, and the measured rollover value is a value that matches the actual rollover movement. Can do.
また、前記従来の寝具の寝返り性の評価方法では、模擬人体を使用するため、各マットレス（寝具）間の違いは分かるものの、顧客にとってどのマットレスが最適であるかの判断がつきにくかった。しかし、本発明では、直接顧客の寝返り性を測定することができるため、その測定データを基にして、顧客にとっての最適なマットレスを従来の方法よりも容易に選ぶことが出来る。また、その測定データを基にして、オーダーメイドで顧客に最適なマットレスを製造することもできる。 In addition, in the conventional method for evaluating the turnability of bedding, since a simulated human body is used, it is difficult to determine which mattress is optimal for the customer, although the difference between the mattresses (bedding) is known. However, in the present invention, it is possible to directly measure the customer's roll-over property, and therefore, an optimal mattress for the customer can be selected more easily than the conventional method based on the measurement data. In addition, based on the measurement data, a mattress that is custom-made and optimal for the customer can be manufactured.
［実施例２］
前記実施例１においては、敷部材１における本体部１ａの長手方向の一端部に、両側が先部ほど縮径するテーパ状に形成された縮径部１ｂを形成したが、図７に示すように、縮径部１Ｂを何れか一方のみを先部ほど縮径するテーパ状に形成してもよいし、図８に示すように縮径部１ｂ，１Ｂを設けなくてもよい。
[Example 2]
In the first embodiment, the diameter-reduced portion 1b formed in a tapered shape whose diameter is reduced toward the tip at both ends is formed at one end in the longitudinal direction of the main body 1a in the laying member 1, as shown in FIG. In addition, the diameter-reduced portion 1B may be formed in a tapered shape in which only one of the diameter-reduced portions is reduced toward the tip, or the diameter-reduced portions 1b and 1B may not be provided as shown in FIG.
敷部材１のその他の構造や、寝具の寝返り性の評価方法は、前記実施例１と同様であるのでその説明を省略する。
本実施例２においても前記実施例１と同様の作用、効果を奏する。
The other structure of the laying member 1 and the method for evaluating the bedding turning ability are the same as those in the first embodiment, and the description thereof is omitted.
Also in the second embodiment, the same operations and effects as the first embodiment are achieved.
［実施例３］
前記実施例１，２においては、敷部材１の本体部１ａの長手方向の幅Ｌ１を、被測定者１１の肩幅より大きく、短手方向の長さＬ２を、肩から背中部に位置するように形成したが、敷部材１における接続部３とは反対側の上に、被測定者１１の少なくとも一方の腕１１ａが位置するように仰臥した状態で、接続部３側に引揚げ力測定手段２を接続して、接続部３を引揚げた際に、敷部材１が一方の腕１１ａで抑えられて、その部位が寝具１０に対して移動しない大きさであれば、任意の大きさ、形状に設定することが出来る。
[Example 3]
In the first and second embodiments, the width L1 in the longitudinal direction of the main body 1a of the laying member 1 is larger than the shoulder width of the person to be measured 11, and the length L2 in the short direction is positioned from the shoulder to the back. In the state where the arm 11a of the person to be measured 11 is positioned on the opposite side of the connecting member 3 in the laying member 1, the lifting force measuring means is connected to the connecting portion 3 side. 2, when the connecting member 3 is lifted, the floor member 1 is restrained by one arm 11 a and the part does not move relative to the bedding 10. It can be set to shape.
例えば、図９〜１１に示すように、本体部１Ａを、被測定者１１の少なくとも一方の腕１１ａが位置するように仰臥した状態で、接続部３に引揚げ力測定手段２を接続して、接続部３を引揚げた際に、本体部１Ａにおける一方の腕１１ａに抑えられた部位が、寝具１０に対して移動しない大きさ、形状に形成し、寝具１０の左右横方向の一方の腕１１ａとは反対側の端部に、紐状部材１５を一本もしくは複数本取付け、この紐状部材１５の先端に接続部３を取り付けるようにしても良い。紐状部材１５の長さは、敷部材１に被測定者１１が仰臥した状態で、接続部３に引揚げ力測定手段２を取り付けることが出来る長さに設定されている。 For example, as shown in FIGS. 9 to 11, the lifting force measuring means 2 is connected to the connecting portion 3 in a state where the main body 1 </ b> A is supine so that at least one arm 11 a of the person to be measured 11 is positioned. When the connecting portion 3 is lifted, a portion of the main body portion 1A that is restrained by one arm 11a is formed in a size and shape that does not move relative to the bedding 10, One or a plurality of string-like members 15 may be attached to the end opposite to the arm 11a, and the connection part 3 may be attached to the tip of the string-like member 15. The length of the string-like member 15 is set to such a length that the lifting force measuring means 2 can be attached to the connecting portion 3 in a state where the person to be measured 11 lies on the floor member 1.
敷部材１のその他の構造や、寝具の寝返り性の評価方法は、前記実施例１と同様であるので説明を省略する。 Since the other structure of the laying member 1 and the evaluation method of the bedding turning ability are the same as those in the first embodiment, the description thereof is omitted.
本実施例３においても前記実施例１と同様の作用、効果を奏する。 Also in the third embodiment, the same operations and effects as the first embodiment are achieved.
