Description
【０００１】
【発明の属する技術分野】
本発明は，耐滑靴底に関するものである。
【０００２】
【従来の技術】
氷上や水でぬれた床面での滑り、転倒は多く、従来からいろいろな工夫がなされている。例えば、
氷上での滑り対策としては、金属スパイクや硬質プラスチックスパイクなどを靴底にはめこみ、スパイクの先端部を氷の表面にくいこませることによって、滑りを防止するものがあり、
水でぬれた床面での滑り対策としては、靴底材料に軟質のゴム、プラスチック、または、これらの発泡材を使用して床面との摩擦抵抗を高くし、滑りを防止するもの、または、織布、不織布を靴底全面に貼り合わせたもの、あるいは、セラミック、グラスウールのような繊維状物質などを靴底材料に混合したものがあった。
【０００３】
【発明が解決しようとする課題】
しかし、これらは、各々に対して効果はあるものの、両者に対しては効果はなかった。特に、スパイクは、硬質であるため、くいこまないと効果はでないので、通常のＰタイル床やコンクリート床上では、逆に滑りやすくなったり、床を傷つけたりしていた。また、歩行もしずらかった。セラミックやグラスウールも床を傷つけるという点では同様であった。また、氷面にしろ、水でぬれた床面にしろ、靴底接地面との間に水の膜ができ、これが摩擦抵抗を下げて滑りの原因となっており、織布や不織布などは、介在する水を吸収するということでは効果がみられるものの、乾いた床面では、逆に滑りやすくなるという問題があった。
本発明は、氷上での滑り、および、水でぬれた床面だけでなく乾いた床面に対して耐滑性を発揮する靴底を提供することを目的とするものである。
【０００４】
【課題を解決するための手段】
本発明は、ゴム靴底において、靴底面から一体に突出した突出部分に前記突出部分に相当する形状、及び面積に合わせた織布または不織布を接着したクリート接地部分とゴムのクリート接地部分とがそれぞれ独立して互い違いに複数存在するように配置することにより、上記の課題を解決するものである。
【０００５】
【発明の実施の形態】
ゴム靴底において、クリート接地部分、すなわち、底意匠を形成すべく靴底面から一体に突出した各突出部分に織布または不織布をはめこんだクリート接地部分とゴムのクリート接地部分とがそれぞれ存在するように配置する。織布または不織布はあらかじめ接着剤を塗布し、靴底ゴムの成形と同時に一体接着成形する。同時成形、すなわち、加圧成形により、ゴムが繊維の間から部分的に通過して、あとから貼り合わせたものより接着強度が向上する。また、接着剤を使用することにより、ゴムとの接着が強固になり、成形後の脱型も容易になる。ゴムの硬さは、低いほどよいが、耐滑性への効果と成形性の点から４５〜６５Ｈｓ（ＪＩＳ Ｋ ６３０１ スプリング式硬度計Ａ形）のゴム材を使用するのがよい。
【０００６】
本発明は、クリート接地部にゴムのクリート接地部分とがそれぞれ存在するように織布または不織布を一層だけはめこむほか、多層にはめこんで一体化することもある。多層にはめこむ場合には、使用中、織布または不織布が摩耗等によって脱落、摩滅しても、織布または不織布がクリート接地部に各々層になっているので、次の層によって永続的に耐滑の効果が持続される。なお、織布または不織布を積層させる場合には、一層目と二層目の織布または不織布の色を変える。これにより、使用者が織布または不織布の摩耗具合を適宜チェックでき、寿命予想が可能となる。
【０００７】
【実施例】
以下図面にもとづいて本発明の実施例を説明すると、織布または不織布には、ナイロン、ポリエステル、ポリウレタン、ポリアミド、ポリエチレンテレフタレートのような化学繊維、綿、麻、スフのような植物繊維、ウールのような動物繊維、レーヨンのような再生繊維を単独で、または、適宜組み合わせて使用する。
次に、本発明の耐滑靴底の製造過程を説明すると、例えば、先ず、ナイロン織布に接着剤を塗布する。次いで、図１および図２に示したゴム靴底１の各クリート接地部分のうち斜線を付したクリート接地部分２に相当する形状、面積に合わせて上記ナイロン織布を裁断してナイロン織布片３を作る。次いで、靴底成形金型のクリート部にナイロン織布片３を一層にしてはめこむ。この場合には、図３に示すようにクリート接地部分２の表面にナイロン織布片３をはめこんでもよく、図４に示すようにクリート接地部分のどちらか一方、例えば、クリート接地部分２には、それらの表面にナイロン織布片３をはめこみ、他方のクリート接地部分４には、それらの肉厚内にナイロン織布片３をはめこんでもよい。なお、ナイロン織布片３を多層にはめこむ場合には、図５に示すようにナイロン織布片３をはめこんだ後、ゴム５を配置し、さらにナイロン織布片３をはめ、またゴム５を配置する作業を繰り返す。上記の作業が済んだら、靴底の容積に応じて裁断、計量した未加硫ゴムを金型に配置する。次いで、所定条件によってゴム靴底の加硫成形をする。これにより、ナイロン織布片３とゴムとの接着とゴム靴底１の成形を行う。図１および図２に示した各クリート接地部分のうち斜線が付されていないクリート接地部分４は、ゴムの接地部分を示す。
【０００８】
上記の構成よりなる耐滑靴底の実験結果を示すと、次の通りである。
乾燥したＰタイルの床および氷面での滑りを体感で評価した。
乾燥したＰタイル床： 傾斜角度を変えられる歩行路上にＰタイルを敷き、靴を履いて立ち、角度を変えていく。
氷面： −３０℃の冷凍庫で２４時間以上保管しておいた平滑な氷を、約２０℃の室温において、傾斜角度を変えられる歩行路上におき、約１時間経過してから靴を履いて氷の上に立ち、角度を変えて滑り感を評価する。
試料には、
Ａ 本発明の実施例の図１に示すようなナイロン織布片をはめこんだ靴底
Ｂ 上記図１と同じクリート（底意匠）のゴムのみの靴底
Ｃ クリート接地部分全部にナイロン織布片をはめこんだ靴底
を使用し、いずれもゴムの硬さは、Ｈｓ５４〜５６（ＪＩＳ Ｋ ６３０１ スプリング式硬度計Ａ型による）とした。
【０００９】
【発明の効果】
本発明は、叙上のように構成したから、氷上での滑り、および、水でぬれた床面だけでなく乾いた床面に対して耐滑性を発揮し、しかも、歩行しやすい靴底を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an anti-skid shoe sole.
[0002]
[Prior art]
There are many slips and falls on the floor surface wet on ice or water, and various devices have been made conventionally. For example,
As measures against slipping on ice, there are things that prevent slipping by fitting metal spikes or hard plastic spikes into the shoe sole, and making the tip of the spike harder to the surface of the ice,
As measures against slipping on the floor surface wet with water, soft rubber, plastic, or these foamed materials are used for the sole material to increase the frictional resistance with the floor surface and prevent slipping, or In some cases, a woven fabric or a non-woven fabric is bonded to the entire surface of the shoe sole, or a fibrous material such as ceramic or glass wool is mixed with the shoe sole material.
[0003]
[Problems to be solved by the invention]
However, these were effective for each, but not for both. In particular, since the spike is hard, it has no effect unless it is swallowed. Therefore, on a normal P tile floor or concrete floor, it becomes slippery or damages the floor. Also, walking was difficult. Ceramics and glass wool were also similar in that they damaged the floor. In addition, even on the ice surface, on the floor surface wet with water, a water film is formed between the shoe sole and the ground surface of the shoe sole, which reduces the frictional resistance and causes slippage. However, although absorbing the intervening water is effective, there is a problem that it becomes slippery on the dry floor surface.
An object of the present invention is to provide a shoe sole exhibiting slip resistance on ice and on a dry floor as well as a floor wet with water.
[0004]
[Means for Solving the Problems]
According to the present invention, in a rubber shoe sole, a cleat grounding portion in which a woven fabric or a nonwoven fabric having a shape corresponding to the projecting portion and an area corresponding to the projecting portion and a rubber cleat grounding portion are integrally projected from a shoe bottom surface. The above-described problems are solved by arranging the plurality so as to exist independently and alternately .
[0005]
DETAILED DESCRIPTION OF THE INVENTION
In a rubber sole, there is a cleat grounding portion, that is, a cleat grounding portion in which a woven fabric or a non-woven fabric is fitted into each projecting portion integrally projecting from the shoe bottom to form a bottom design, and a rubber cleat grounding portion Arrange so that. A woven fabric or a non-woven fabric is coated with an adhesive in advance, and is integrally bonded and molded simultaneously with the molding of the shoe sole rubber. By simultaneous molding, that is, pressure molding, the rubber partially passes from between the fibers, and the adhesive strength is improved as compared with those bonded later. Further, by using an adhesive, the adhesion with rubber becomes strong, and demolding after molding becomes easy. The lower the hardness of the rubber, the better, but it is preferable to use a rubber material of 45 to 65 Hs (JIS K 6301 spring type hardness tester A type) from the viewpoint of the effect on slip resistance and moldability.
[0006]
In the present invention, a woven fabric or a non-woven fabric is inserted into only one layer such that a rubber cleat grounding portion is present in the cleat grounding portion, and may be integrated by being multilayered. When inserting into multiple layers, even if the woven fabric or non-woven fabric falls off or wears out due to wear or the like during use, the woven fabric or non-woven fabric is layered on the cleat grounding part. The effect of slip resistance is maintained. In addition, when laminating a woven fabric or a nonwoven fabric, the colors of the first and second layers of the woven fabric or nonwoven fabric are changed. As a result, the user can appropriately check the wear condition of the woven fabric or the non-woven fabric, and the life can be predicted.
[0007]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The woven or non-woven fabric may be made of chemical fibers such as nylon, polyester, polyurethane, polyamide, polyethylene terephthalate, vegetable fibers such as cotton, hemp, sufu, wool. Such animal fibers and regenerated fibers such as rayon are used alone or in appropriate combination.
Next, the production process of the anti-skid shoe sole of the present invention will be described. For example, first, an adhesive is applied to a nylon woven fabric. Next, the nylon woven fabric piece is cut by cutting the nylon woven fabric in accordance with the shape and area corresponding to the hatched
[0008]
The experimental results of the anti-skid shoe sole having the above structure are as follows.
The dry P-tile floor and the slip on the ice surface were evaluated by bodily sensation.
Dry P tile floor: P tile is laid on a walking path that can change the tilt angle, shoes are put on, and the angle is changed.
Ice surface: Place smooth ice that has been stored in a freezer at -30 ° C for more than 24 hours on a walking path where the angle of inclination can be changed at room temperature of about 20 ° C. Stand on the ice and change the angle to evaluate the slip.
Samples include
A A shoe sole B fitted with a nylon woven cloth piece as shown in FIG. 1 of the embodiment of the present invention B A rubber-only shoe sole C of the same cleat (bottom design) as shown in FIG. The soles were fitted with a rubber sole having a hardness of Hs 54 to 56 (according to JIS K 6301 spring type hardness tester A type).
[0009]
【The invention's effect】
Since the present invention is configured as described above, a shoe sole that exhibits slip resistance on a dry floor as well as a slip on ice and a floor wet with water, and that is easy to walk is provided. Can be provided.
