Description
本発明は、床面、路面等の測定面の滑り抵抗値を測定するための滑り抵抗測定装置に関する。 The present invention relates to a skid resistance measuring device for measuring the skid resistance value of a measurement surface such as a floor surface or road surface.
従来より、床面、路面等の測定面の滑り抵抗値を測定するための滑り抵抗測定装置が提供されている。具体的には、測定方法や測定装置に関して、ＪＩＳ Ａ １４５４：２０１０（非特許文献１）で定められている。 Conventionally, there have been provided slip resistance measuring devices for measuring the slip resistance value of a measurement surface such as a floor surface or a road surface. Specifically, the measurement method and measuring device are specified in JIS A 1454:2010 (Non-Patent Document 1).
しかしながら、ＪＩＳで定められている滑り抵抗測定装置は、大きさが大きく重量もあることから、実際に存在する階段の踏み板のような狭いスペースの滑り抵抗を図ることは、基本的にできない。また、ＪＩＳで定められている滑り抵抗測定装置を用いて厳格に滑り抵抗値を測定しようとすると、測定の準備が煩雑で測定したい現場で容易に測定することが困難である。実際の滑り抵抗を測定する必要がある場面では、床面等の滑り具合を目安として簡易的に測定すれば良い機会が多い。 However, the slip resistance measuring device specified by the JIS is large and heavy, so it is basically unable to measure the slip resistance in a small space such as an actual staircase tread. Furthermore, if you try to measure the slip resistance value strictly using the slip resistance measuring device specified by the JIS, the measurement preparation is complicated and it is difficult to easily measure at the desired site. In situations where it is necessary to measure actual slip resistance, there are many occasions where a simple measurement can be made using the slipperiness of the floor surface as a guide.
本発明は、このような事情に鑑みてなされたもので、簡易的な仕組みで容易に滑り抵抗値を測定可能な滑り抵抗測定装置を提供することにある。 The present invention was made in consideration of these circumstances, and aims to provide a slip resistance measuring device that can easily measure slip resistance values using a simple mechanism.

請求項７記載の滑り抵抗測定装置は、荷重測定器が、測定した荷重値を電子データで出力可能なデジタルフォースゲージであり、携帯情報端末に電子データを受け渡すことが可能であることを特徴とする。 The slip resistance measuring device described in claim 7 is characterized in that the load measuring device is a digital force gauge capable of outputting the measured load value as electronic data, and that the electronic data can be transferred to a mobile information terminal.
本願の発明によれば、荷重測定器と滑り片台座と引張荷重速度調整器とを備え、滑り片台座の接地面に、滑り片台座が牽引される方向に沿って伸びる少なくとも２筋の所定の硬度を有する滑り片が配置されている程度で、簡易的な仕組みで容易に滑り抵抗値を測定可能である。 According to the present invention, the slip resistance value can be easily measured with a simple mechanism that includes a load measuring device, a sliding piece base, and a tensile load speed regulator, and at least two sliding pieces with a predetermined hardness that extend in the direction in which the sliding piece base is pulled are arranged on the contact surface of the sliding piece base.

図における滑り抵抗測定装置１は、床面、路面等の測定面の滑り抵抗値を測定するためのものである。滑り抵抗測定装置１は、荷重測定器であるデジタルフォースゲージ３０、滑り片台座１０、引張荷重速度調整器であるコイルバネ４０、牽引ワイヤ４２等で構成されている。 The skid resistance measuring device 1 in the figure is used to measure the skid resistance value of a measurement surface such as a floor surface or road surface. The skid resistance measuring device 1 is composed of a digital force gauge 30 which is a load measuring device, a sliding piece base 10, a coil spring 40 which is a tensile load speed regulator, a traction wire 42, etc.
デジタルフォースゲージ３０は、フック３０ａの部分に加えられた引っ張り力を荷重値として測定するもので、測定した荷重値を電子データで外部に出力可能なものである。尚、本実施の形態では、荷重測定器としてデジタルフォースゲージを使用しているが、電子データを出力可能なものでなくても滑り抵抗測定装置１の荷重測定器としては使用可能である。 The digital force gauge 30 measures the pulling force applied to the hook 30a as a load value, and is capable of outputting the measured load value as electronic data to the outside. Note that in this embodiment, a digital force gauge is used as the load measuring device, but even devices that are not capable of outputting electronic data can be used as the load measuring device for the slip resistance measuring device 1.
滑り片台座１０は、測定面Ｆに載置し、荷重測定器であるデジタルフォースゲージ３０を移動させることでデジタルフォースゲージ３０によって牽引されるものである。滑り片台座１０が、測定面Ｆの上を引き摺られるような状態になり、滑り片台座１０と測定面Ｆとの間に滑り抵抗値を計測することになる（実際に、測定面Ｆに接しているのは、後述する滑り片２０）。 The sliding piece base 10 is placed on the measurement surface F, and is pulled by the digital force gauge 30, which is a load measuring device, as the digital force gauge 30 is moved. The sliding piece base 10 is dragged over the measurement surface F, and the sliding resistance value is measured between the sliding piece base 10 and the measurement surface F (in reality, it is the sliding piece 20, described later, that is in contact with the measurement surface F).
滑り片台座１０は、測定面Ｆとの接地面側（接地側面１０ａａ）が、ほぼ平坦な面を有していれば良いが、本実施の形態の滑り片台座１０では、滑り片台座１０が牽引される側が、少し上昇した傾斜を有する形状になっている。また、滑り片台座１０の材質は、特に限定されるものではないが、後述する所定の重さを必要となるため、金属製であることが望ましい。 The sliding piece base 10 may have a nearly flat surface on the contact surface side (contact surface side 10aa) with the measurement surface F, but in the present embodiment, the sliding piece base 10 has a shape with a slight upward incline on the side on which the sliding piece base 10 is towed. In addition, the material of the sliding piece base 10 is not particularly limited, but it is preferably made of metal because it needs to have a certain weight, which will be described later.
滑り片台座１０は、滑り片台座１０が牽引される側にフック１２を有し、引張荷重速度調整器であるコイルバネ４０、牽引ワイヤ４２を介して、デジタルフォースゲージ３０のフック３０ａに連結されている。引張荷重速度調整器は、デジタルフォースゲージ３０を移動させた場合に、牽引される滑り片台座１０が、同時に急峻に移動したりして慣性力の影響を受けてしまったりといった他の力学的な作用を極力排除して、より正確な滑り抵抗値の測定を可能にするための仕組みである。尚、引張荷重速度調整器の構成としては、コイルバネ４０と牽引ワイヤ４２とで構成されるものに限定されず、同様な作用・効果が見込めるものであれば、どのような構成であってもよい。 The sliding piece base 10 has a hook 12 on the side where the sliding piece base 10 is pulled, and is connected to the hook 30a of the digital force gauge 30 via a coil spring 40 and a pulling wire 42, which are tension load speed regulators. The tension load speed regulator is a mechanism for enabling more accurate measurement of the slip resistance value by eliminating other mechanical effects, such as the sliding piece base 10 being pulled and moving sharply at the same time and being affected by inertial forces, when the digital force gauge 30 is moved. The configuration of the tension load speed regulator is not limited to one consisting of a coil spring 40 and a pulling wire 42, and any configuration may be used as long as it is expected to have the same action and effect.
滑り片台座１０の測定面Ｆとの接地面（接地側面１０ａａ）に、滑り片台座１０が牽引される方向に沿って伸びる２筋の所定の硬度を有する滑り片２０が配置されている。図に示す滑り片２０は、滑り片台座１０の接地側面１０ａａの両脇に、２本設けられているが、少なくとも２筋（２本）で、滑り片台座１０が牽引される方向に対して左右均等になるように配置されていれば本数にこだわるものではないが、滑り片２０は、接地側面１０ａａの全面に配置されている必要はない。 Two sliding pieces 20 having a predetermined hardness are arranged on the contact surface (contact side 10aa) of the sliding piece base 10 with the measurement surface F, extending in the direction in which the sliding piece base 10 is pulled. The sliding pieces 20 shown in the figure are provided on both sides of the contact side 10aa of the sliding piece base 10, but the number is not important as long as there are at least two stripes (two pieces) and they are arranged evenly on the left and right in the direction in which the sliding piece base 10 is pulled, but the sliding pieces 20 do not need to be arranged over the entire surface of the contact side 10aa.
滑り片２０は、１筋（１本）が幅８ｍｍ～１５ｍｍ、長さ５０ｍｍ～１２０ｍｍであることが望ましく、また、硬度（タイプＡ ＪＩＳ Ｋ ６２５３－３：２０１２ ショアＡ硬度）が４０～８０の、樹脂製、シリコーン製、ゴム製又は革製であることが望ましい。さらに、滑り片台座１０の重量が１．５ｋｇ～５．０ｋｇであることが望ましい。尚、より厳密には、滑り片２０は、１筋（１本）が幅９ｍｍ～１５ｍｍ、長さ６０ｍｍ～１１０ｍｍ、また、硬度（タイプＡ ＪＩＳ Ｋ ６２５３－３：２０１２ ショアＡ硬度）は樹脂製、シリコーン製、ゴム製又は革製で５０～７０、滑り片台座１０の重量が２．０ｋｇ～５．０ｋｇに限定してもよい。 It is preferable that each strip of the sliding piece 20 is 8mm to 15mm wide and 50mm to 120mm long, and is made of resin, silicone, rubber or leather with a hardness (Type A JIS K 6253-3:2012 Shore A hardness) of 40 to 80. It is also preferable that the weight of the sliding piece base 10 is 1.5kg to 5.0kg. More strictly, the sliding piece 20 may be limited to a strip of 9mm to 15mm wide and 60mm to 110mm long, with a hardness (Type A JIS K 6253-3:2012 Shore A hardness) of 50 to 70 for resin, silicone, rubber or leather, and the weight of the sliding piece base 10 to 2.0kg to 5.0kg.
尚、本実施の形態の滑り片台座１０は、１つの部材で構成させるようにしても良いが、本実施の形態では、図４に示すように、滑り片台座１０が、台座本体１０ａと積み重ね可能な積層部材１０ｂ～１０ｄとからなり、積層部材１０ｂ～１０ｄを着脱することで、滑り片台座１０の重量を可変可能な構成にするようにしてもよい。台座本体１０ａ及びそれぞれの積層部材１０ｂ～１０ｄは、積層方向に穿設された孔を有し、その孔に円柱状の連結ピン１４ａ～１４ｃを挿嵌させて、各積層部材１０ｂ～１０ｄがずれないように固定される形態になっている。 In addition, the sliding piece base 10 of this embodiment may be constructed from a single member, but in this embodiment, as shown in FIG. 4, the sliding piece base 10 may be constructed from a base body 10a and stackable laminated members 10b-10d, and the weight of the sliding piece base 10 may be made variable by attaching and detaching the laminated members 10b-10d. The base body 10a and each of the laminated members 10b-10d have holes drilled in the stacking direction, and cylindrical connecting pins 14a-14c are inserted into the holes to fix each of the laminated members 10b-10d in place.
また、荷重測定器として、測定した荷重値を電子データで出力可能なデジタルフォースゲージ３０を用いることにより、図７に示すように、デジタルフォースゲージ３０と携帯情報端末１００とプリンタ１２０とからなる構成にし、デジタルフォースゲージ３０が、携帯情報端末１００に電子データを受け渡すことが可能な構成で使用するようにしてもよい。具体的には、例えば、デジタルフォースゲージ３０で測定した荷重値のデジタルデータを、有線又は無線で、携帯情報端末１００に送り、携帯情報端末１００側で、受け取った荷重値を滑り抵抗値に計算し（何回かの平均を行ったり、複数回の計測値の最大と最小を切り捨てたり等の計算処理を行ってもよい）、滑り抵抗値を携帯情報端末１００に表示させる。さらに、滑り抵抗値を、携帯情報端末１００から、有線又は無線で、プリンタ１２０に送り、プリンタ１２０で印刷させるようにしてもよい。 In addition, by using a digital force gauge 30 capable of outputting the measured load value as electronic data as the load measuring device, as shown in FIG. 7, a configuration consisting of the digital force gauge 30, a mobile information terminal 100, and a printer 120 may be used, in which the digital force gauge 30 is capable of transferring electronic data to the mobile information terminal 100. Specifically, for example, the digital data of the load value measured by the digital force gauge 30 may be sent to the mobile information terminal 100 by wire or wirelessly, and the mobile information terminal 100 may calculate the received load value into a slip resistance value (may perform calculation processing such as averaging several times or discarding the maximum and minimum of several measured values), and display the slip resistance value on the mobile information terminal 100. Furthermore, the slip resistance value may be sent from the mobile information terminal 100 by wire or wirelessly to the printer 120, and printed by the printer 120.
さらに、図８に示すように、デジタルフォースゲージ３０を略直線的に移動させるための荷重測定器用台車３２を設けるようにしてもよい。荷重測定器用台車３２は、上面にデジタルフォースゲージ３０を載置可能で、また下面には車輪３４を備えている。図８に示すように、荷重測定器用台車３２も測定面Ｆに置き、デジタルフォースゲージ３０を、荷重測定器用台車３２に乗せた状態で測定面Ｆの上を走らせるように移動させると、デジタルフォースゲージ３０を容易に略直線的に移動させることができる。 Furthermore, as shown in FIG. 8, a load measuring device dolly 32 may be provided for moving the digital force gauge 30 in a substantially linear manner. The load measuring device dolly 32 is capable of placing the digital force gauge 30 on its upper surface, and is provided with wheels 34 on its lower surface. As shown in FIG. 8, the load measuring device dolly 32 is also placed on the measurement surface F, and the digital force gauge 30 is moved so as to run on the measurement surface F while placed on the load measuring device dolly 32, whereby the digital force gauge 30 can be easily moved in a substantially linear manner.
このような構成の滑り抵抗測定装置１によれば、荷重測定器であるデジタルフォースゲージ３０と滑り片台座１０と引張荷重速度調整器（コイルバネ４０）とを備え、滑り片台座１０の接地側面１０ａａに、滑り片台座１０が牽引される方向に沿って伸びる少なくとも２筋の所定の硬度を有する滑り片２０が配置されている程度で、簡易的な仕組みで容易に滑り抵抗値を測定可能である。 The slip resistance measuring device 1 configured in this way is equipped with a digital force gauge 30, which is a load measuring device, a sliding piece base 10, and a tensile load speed regulator (coil spring 40), and at least two sliding pieces 20 with a predetermined hardness are arranged on the ground contact side 10aa of the sliding piece base 10, extending in the direction in which the sliding piece base 10 is pulled, making it possible to easily measure the slip resistance value with a simple mechanism.
以下の実施例では、測定実験を実際に行った滑り片台座１０及び滑り片２０による滑り抵抗測定装置１による滑り抵抗値と、従来測定装置であるＪＩＳ（ＪＩＳ Ａ １４５４：２０１０ 高分子系張り床材試験方法）で定められた方法に厳格な滑り抵抗測定装置による滑り抵抗値と対比を説明する。 In the following examples, we will explain the comparison of slip resistance values measured by the slip resistance measuring device 1 using the sliding piece base 10 and sliding piece 20 used in the actual measurement experiment, with the slip resistance values measured by a conventional measuring device that strictly follows the method specified in JIS (JIS A 1454:2010 Test method for polymer-based floor coverings).
滑り抵抗測定装置１は、滑り片台座１０の重さが２ｋｇ、滑り片台座１０の幅が８０ｍｍであるが、滑り片２０は、幅１０ｍｍで長さが８５ｍｍで、ゴムで、硬度は、シェアＡ硬度で７０と５０の２種類で、左右に同じ硬度のものを２筋貼付して各測定を行った。 The sliding resistance measuring device 1 has a sliding piece base 10 weighing 2 kg and a width of 80 mm, while the sliding piece 20 is 10 mm wide and 85 mm long and made of rubber with two different hardnesses, 70 and 50 on the Shear A hardness scale. Two strips of the same hardness were attached to the left and right sides to perform each measurement.
尚、対比対象の従来測定装置は、東北測器社製のＯＮＯ－ＰＰＳＭで、滑り片台座の重さが２０ｋｇ、滑り片が滑り片台座の幅方向の全面に貼付され、その幅が５０ｍｍで最長部分の長さが６０ｍｍ、滑り片の材質は、ゴムで、硬度は、シェアＡ硬度で８０である。 The conventional measuring device used for comparison is the ONO-PPSM manufactured by Tohoku Sokki Co., Ltd., with a sliding piece base weighing 20 kg, a sliding piece attached to the entire width of the sliding piece base, a width of 50 mm, and a length of 60 mm at the longest part. The sliding piece is made of rubber, with a hardness of 80 on the Shear A scale.
測定面Ｆは、御影石の平滑な床材用のタイル面で、床面での転倒を防止するための塗布材である防滑材（株式会社名倉ルーフの商品名：クリアグリップ）を塗布していない未施工、当該防滑材を塗布してＣＧ＃７０相当、ＣＧ＃４０相当、ＣＧ＃３０相当の荒さに整えた面で、それぞれ測定を行った（ＣＧ＃は、サンドペーパーの表面の目の粗さを示す番手を目安にした値）。 Measurement surface F was a smooth granite flooring tile surface. Measurements were taken on an untreated surface that was not coated with an anti-slip coating (product name: Clear Grip, manufactured by Nagura Roof Co., Ltd.), which is a coating material used to prevent falls on floor surfaces, and on a surface that had been coated with the anti-slip coating and smoothed to a roughness equivalent to CG#70, CG#40, or CG#30 (CG# is a value based on the grit size of sandpaper, which indicates the roughness of the surface).
また、図５に示すグラフは、測定面Ｆが乾燥した状態で、図６に示すグラフは、測定面Ｆに霧吹きで水滴を塗布して湿潤状態にした場合のものである。 The graph shown in Figure 5 is for the case where the measurement surface F is dry, while the graph shown in Figure 6 is for the case where the measurement surface F is wetted by applying water droplets to it with a spray bottle.
さらに、測定自体は、各５回測定を行って、最大値と最小値を落として中央値３回分を平均した値であるが、この各５回測定を行って、最大値と最小値を落として中央値３回分を平均した値を求めること自体を各２回行って、その２回の平均を行った値のグラフが図５及び図６に示すものである。 Furthermore, the measurements themselves were taken 5 times, the maximum and minimum values were dropped, and the median values of the 3 measurements were averaged. This process of taking 5 measurements, dropping the maximum and minimum values, and averaging the 3 median values was carried out twice for each measurement, and the graphs of the averages of these two measurements are shown in Figures 5 and 6.
図５及び図６のグラフから明らかなように、本願の滑り抵抗測定装置１で測定した滑り抵抗値であっても、従来測定装置で測定した滑り抵抗値であっても、図５の乾燥状態に比べ、図６の湿潤状態での滑り抵抗値の方が小さく、湿潤状態の方が滑りやすいことを共に示している。また、乾燥状態にしても湿潤状態にしても、本願の滑り抵抗測定装置１で測定した滑り抵抗値であっても、従来測定装置で測定した滑り抵抗値であっても、ＣＧ＃の番手が大きい方が目が細かく滑り抵抗値が小さくて滑りやすいことを共に示している。 As is clear from the graphs of Figures 5 and 6, whether the slip resistance value is measured with the slip resistance measuring device 1 of the present application or with a conventional measuring device, the slip resistance value in the wet state of Figure 6 is smaller than the dry state of Figure 5, indicating that the wet state is more slippery. Also, whether the slip resistance value is measured with the slip resistance measuring device 1 of the present application or with a conventional measuring device, whether in a dry state or a wet state, the larger the CG# number, the finer the mesh, the smaller the slip resistance value, and the more slippery the surface is.
このように、本願の滑り抵抗測定装置１で測定した滑り抵抗値が、従来測定装置で測定した滑り抵抗値と一定の相関関係を持ったといえる値になっており、滑り抵抗値の簡易測定においては、本願の滑り抵抗測定装置１の測定が妥当性を有しているといえる。 In this way, the slip resistance values measured with the slip resistance measuring device 1 of the present application can be said to have a certain correlation with the slip resistance values measured with conventional measuring devices, and it can be said that the measurements made with the slip resistance measuring device 1 of the present application are valid for simple measurements of slip resistance values.
本発明は、本発明の広義の精神と範囲を逸脱することなく、様々な実施の形態及び変形が可能とされるものである。また、上述した実施の形態は、この発明を説明するためのものであり、本発明の範囲を限定するものではない。すなわち、本発明の範囲は、実施の形態ではなく、請求の範囲によって示される。そして、請求の範囲内及びそれと同等の発明の意義の範囲内で施される様々な変形が、この発明の範囲内とみなされる。 The present invention allows for various embodiments and modifications without departing from the broad spirit and scope of the present invention. Furthermore, the above-described embodiments are intended to explain the present invention and do not limit the scope of the present invention. In other words, the scope of the present invention is indicated by the claims, not the embodiments. Furthermore, various modifications made within the scope of the claims and within the scope of the meaning of the invention equivalent thereto are considered to be within the scope of the present invention.
以上のように、本発明によれば、簡易的な仕組みで容易に滑り抵抗値を測定可能な滑り抵抗測定装置を提供することができる。 As described above, the present invention provides a slip resistance measuring device that can easily measure slip resistance values using a simple mechanism.
