The invention is best understood from the following detailed description when read with the accompanying drawings.
Impact protection material 102 forms a gutter 116 to retain liquid absorbed and transported by absorbent material 104 and moisture transport material 106. A mechanism 108, 110 for the protective garment to be secured to a user is also provided. It is noted that the article can be folded in the reverse direction and still exhibit some or all of the benefits as when folded with the absorbent material in the interior of the fold. These benefits will be described in more detail below.
It is noted that combinations of features shown in, and described with respect to
The novel system provides impact protection and moisture control in a single product. Traditional technology requires an impact protective material to have some form of openings to render the material breathable. This can compromise the protective benefits of the material and add additional manufacturing expense. The novel system combines an impact protective material with a moisture absorbent layer and a moisture transport material to direct moisture away from the skin. The impact protection material may or may have openings.
The moisture transport material creates a capillary action that transports moisture toward the absorbent material. If the absorbent material becomes saturated, the gutter formed by the u or v-shaped impact protection material acts as a reservoir to inhibit moisture dripping onto the wearer. An article made of the layered material and folded as shown in
In an illustrative embodiment of the invention, a component to maintain the article in a folded position is included. For example, as shown in
The order of materials can be varied, however, it has been determined that having the moisture transport material against the user is most effective for moisture control. It is also possible to have either the impact protection layer as single, rather than a folded layer, but the gutter effect would be sacrificed.
Various materials can be used to provide the desired characteristics of each layer of the protective article. The impact protection material may be for example, an open cell foam such as polyethylene bubble foam. Other synthetic materials may also be used, such as neoprene. Natural rubber materials are another option for the impact protection layer.
The absorbent material layer is preferably a terry cloth or similar material. Cotton or cotton-containing materials in general are an excellent choice for the absorbent layer. The absorbent layer may also exhibit a capillary effect along the material, rather than through it. This can facilitate the transfer of moisture into the gutter.
The moisture transport layer can be any material in which a capillary effect can be created through the material. Wicking materials such as those made by Under Armor®, Adidas®, Nike® and Gortex® are suitable in addition to other types/brands. Gortex®, for example has a porous fluoropolymer membrane with a urethane coating bonded to a fabric such as nylon or polyester. The membrane has approximately nine billion pores per square inch, making them permeable to water vapor but not liquid water. Generally, a material that blocks liquid water but lets water vapor pass through is suitable for the moisture transport layer. This allows moisture generated by the wearer to pass through to the absorbent layer, but will not let liquid water vapor pass back to the wearer when the absorbent material becomes saturated. Wicking materials can enhance the moisture control of the article by wicking moisture away from the user while drawing moisture toward the absorbent layer through the capillary effect.
The construction of the layered material can affect the moisture control ability of the article. The moisture transported by the moisture transport material must reach the absorbent material for the article to be effective. Accordingly, an interface should exist between the two materials. The interface can be to any extent and need not be face to face. Therefore, overlap of one material on another and the type of seam used can have a bearing on the effectiveness of the article. The moisture transport material can overlap the absorbent material, such that the moisture transport material folds over the edge of the absorbent material, thereby facilitating the absorbent material's absorption of moisture wicked away from the wearer by the moisture transport layer. The materials may be permanently attached to one another or separable to facilitate cleaning and/or allow interchangeability of components.
The protective system may be used to form many different articles. Examples of use include, a headband, neckband, wristband, armband, knee or ankle support, and shin guard.
The layered material can also be used for therapeutic purposes. For example, migraine sufferers may use the system in the form of a headband or cap that can hold cold packs to their head. Eye shields can be incorporated into the article to help with light sensitivity. The layered material may also be used to hold other therapeutic devices to a user such as hot packs and vibration devices. A band soaked in cold water could be a cooling device. In an illustrative embodiment of the invention, an article comprising the layered material has an attachment component to attach a therapeutic device. This may be for example, a pocket or a fastening device.
While the invention has been described by illustrative embodiments, additional advantages and modifications will occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to specific details shown and described herein. Modifications, for example, types of material and configurations of articles made with material may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the invention not be limited to the specific illustrative embodiments, but be interpreted within the full spirit and scope of the appended claims and their equivalents.
