LINING FOR WATER-PROOF CLOTHING Filed Sept. e, 195e l 2 sheets-sheet 2 HANS KLEPPe@ INVENTOR @Wigan/r1.5 mrwww v BM ATTORNEYS,

United States Patent() LINING FOR WATER-PROOF CLOTHING Hans Klepper, Rosenheim, Upper Bavaria, Germany Application September 6, 1956, Serial No. 608,300 Claims priority, application Germany December 29, 1.955 p 7 Claims. (Cl. 2'-97) .The present invention relates to a novel liningfor water-proof material as well as to the combination of water-proof outer clothing with the novel lining.

A disadvantage attending use of water-proof clothing formed of impervious sheet material such as rubber resides in the fact that water vapor within the clothing has no opportunity to escape and thus condenses on the inside surface. Activity on the part of the wearer results in perspiration which aggravates the problem so that the wearer is extremely uncomfortable.

As a partial solution it is possible to aflix spacers to the underside of the clothing so that the clothing will not be held directly against the body and so that room will be provided for the circulation of air between the body and the clothing, thereby removing excess water vapor and condensed moisture. To this end the water-proof material may be provided with spaced webs or strips of fabric on its underside to form longitudinally extending channels running from top to bottom.

Even so the problem is not satisfactorily solved since the points where the spacer webs contact the body are not subjected to circulation of air. If the strips are made narrow and spaced a considerable distance apart in order to have less contact with the body, then the waterproof material is free to sag and thereby reduce the cross-section of the air channels. In addition, the sagging waterproof material may directly contact the body intermediate the spacers.

It is accordingly an object of the present invention to provide a lining suitable for water-proof clothing, which lining will substantially eliminate condensation of water on the underside of the clothing.

Another object of the invention is to provide a lining for water-proof clothing which will permit circulation of air and which will prevent accumulation of moisture-laden air substantially everywhere between the body and the outer fabric.

These and other objects and advantages are realized in accordance with the present invention wherein there is provided a lining composed of spaced pieces of porous cellular material held together by a loose matrix or lattice of weaving or knitting rthreads. The cellular material may comprise natural or synthetic rubber which has been foamed or otherwise formed into a sponge and can be formed either as a plurality of parallel strips or a checkerboard arrangement of pieces held in position by cross-threads.

Thus, even if the sponge rubber of the lining contacts the body over an appreciable area circulation of air will still be possible due to the porosity and permeability of the sponge rubber to air. In addition, the sponge rubber is moisture absorbent and thus can take up any excess moisture so as to prevent condensation or minimize the discomfort otherwise attending such condensation.

The invention will now be described more fully with yreference to the accompanying drawing, wherein:

ICE

2 the inside and provided with a lining in accordance with the present'invention.

Fig. 2 is a section taken along line lI--II of Fig. l.

Fig. 3 is an elevation of a lining made in accordance with the invention, showing a checkerboard arrangement of pads.

Fig. 4 is an elevation of a coat showing the lining of Figure 3 applied thereto, and

Fig. 5 shows the lining of Figure 2 without the clothmg.

Referring now more particularly tto the drawing, there is shown a piece of clothing 1 formed of water-proof material such as rubber or rubberized textile material. The inside of the clothing 1'is provided with a lining Z which may be aiixed tothe water-proof material by an adhesive, by sewing in along the seams, or the like. Alternatively, the lining 2 may be independent of the clothing 1 and may be put on separately as an undergarment.

The lining may be coextensive with the clothing 1 or as shown may only be provided for certain parts of the body which would normally come in contact with the clothing when worn, such as across the shoulders, chest and possibly the arms.

The lining 2 consists of a loose or open weaving or knitting into which spaced strips 3 of foam or sponge rubber or other porous cellular polymeric material are incorporated. The positioning is effected by cross-threads 4 extending transversely which are connected with longitudinally extending threads or chains of stitches 6. Between the first and second chains 6 a sponge rubber strip 3 is inserted and is held in place due to the fact that some threads 4 pass in front of the strip 3 and others behind the strip. Between the second and third chains 6 the cross-threads 4 -do not contact any sponge rubber inserts and thus substantially unimpaired channels 5 are formed, alternated with the strips 3.

The sponge rubber pieces permit a ready circulation of air through the longitudinal channels 5 and because of their porosity take up excess water vapor and/ or condensed moisture. When the formation of water vapor is reduced as during rest, the circulating air can then remove any Water previously absorbed by the sponge rubber. Because of the porous cellular nature of the sponge rubber, the cross-section of the channels 5 can be relatively small compared to the width of the strips 3 and air Will still be capable of circulating. The sponge rubber spacers can also be laid out in other patterns, such as a checkerboard, with the pieces either spaced from each other or contacting each other at the corners. In the latter case, circulation of air will still be possible because of its ability to pass through the cellular pieces.

Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.

What is claimed is:

l. A lining material for clothing and the like comprising a loose, open mesh fabric formed of a plurality of united groups of transversely and longitudinally extending threads, one of said groups delining a series of rows, a plurality of porous, cellular, absorbent pads disposed in spaced relation to each other throughout said rows, said pads being supported in said relationship by said transverse threads.
