Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application Ser. No. 62/684,867, filed Jun. 14, 2018, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Technical Field

This invention relates generally to protective textile sleeves for providing protection to elongate members contained therein, and more particularly to textile sleeves having an elastomeric coating with indicator markings therein.

2. Related Art

Protective textile sleeves for providing protection to elongate members extending therethrough are known. Protective textile sleeves having a circumferentially continuous, closed wall or a wrappable wall with opposite lengthwise extending edges configured to be wrapped into overlapping relation with one another are also known. In some cases, the aforementioned known sleeves have elastomeric coatings for added protection to the contents contained within the sleeves. It is further known to include indicia on an outer surface of the sleeves for identification purposes, such as a name and/or product number, wherein the indicia is typically provided with ink, via inkjet technology, pad printing or other ink applications. Although the aforementioned indicia can prove useful initially, problems can arise via degradation of the indicia being worn away, particularly when exposed to heat and/or fluids.

These and other aspects, features and advantages of the present disclosure will become more readily appreciated when considered in connection with the following detailed description of presently preferred embodiments and best mode, appended claims and accompanying drawings, in which:

FIG. 1 is a perspective view of a protective sleeve having a circumferentially continuous, seamless wall in accordance with one aspect of the disclosure shown fixed about an elongate member to be protected;

FIG. 2 is a perspective view of a protective sleeve having a wrappable wall in accordance with another aspect of the disclosure shown fixed about an elongate member to be protected; and

FIG. 3 is an enlarged cross-sectional view taken generally along the line 3-3 of FIG. 1.

DETAILED DESCRIPTION OF PRESENTLY PREFERRED EMBODIMENTS

Referring in more detail to the drawings, FIGS. 1 and 2 illustrate sleeves 10, 10′ having a circumferentially continuous, seamless wall 12 and a wrappable wall 12′, respectively, for routing and protecting an elongate member 14, such as a cable, wire harness, or tube, by way of example and without limitation. The elongate wrappable wall 12′ has opposite inner and outer free sides or side edges, also referred to simply as edges 16, 17, extending generally parallel to a central longitudinal axis 18, while both walls 12, 12′ extend between opposite open ends 19, 20; 19′, 20′, respectively. The opposite edges 16, 17 of the wrappable wall 12′ can be biased into overlapping relation with one another in “cigarette wrapped” fashion, such as via a heat-set formed in yarns of the wall 12′, to fully enclose the elongate member(s) 14 within a central cavity C of the sleeve 10′. The walls 12, 12′ have an innermost face or surface, also referred to as inner surface 21, 21′ and an outermost face or surface, also referred to as outer surface 23, 23′, wherein the cavity C is defined and bounded by the innermost surface 21, 21′. The walls 12, 12′ are formed of interlaced yarn(s) 25 (shown in separate partially broken away areas of FIGS. 1 and 2, wherein the yarn(s) 25 can be woven, knit or braided, as shown, wherein it is to be understood that the illustrations shows the different mechanisms for interlacing the yarn(s), however, only one is performed for any one sleeve), which can include monofilaments and/or multifilaments, and a coating 27 of elastomeric material bonded to an outer surface 29, 29′ of the walls 12, 12′. The coating 27 has an indicia 28, including any desired symbol(s), number(s), letter(s), and the like, therein to provide a viewer viewing an outer surface 30 of the coating 27 with information, wherein the indicia 28 extends radially inwardly into the outer surface 30 of the coating 27 toward the central longitudinal axis 18 to provide the indicia 28 with depth (d) so as to avoid being easily worn away. Accordingly, the sleeves 10, 10′ can be shipped, stored and used without concern of the indicia 28 being worn away.
The indicia 28 does not extend through an entire thickness (t) of the coating 27 so as to avoid exposing the underlying outer surface 29, 29′ of the interlaced yarn(s) 25. Accordingly, the depth d is less than the thickness t such that the yarns 25 remain fully protected by the coating 27 over the entirety of the sleeve 10, 10′, including the region of the indicia 28, thereby avoiding exposure of the yarn 25 to environmental elements (debris, thermal conditions. In accordance with one aspect, the depth d of the indicia 28 is between about 25-75 percent of the thickness t of the coating 27, and in accordance with a further aspect, to best ensure the indicia 28 is not worn away, the depth d of the indicia 28 is greater than 50 percent of the thickness t of the coating 27, but less than 75 percent of the thickness t to avoid unwanted exposure of the underlying yarn(s) 25.
The elastomeric material of the coating 27 can be provide as a silicone-based material, and the yarn(s) 25 can be interlaced via being woven, braided or knitted.
In accordance with another aspect of the disclosure, a method of constructing a textile protective sleeve 10, 10′ is provided. The method includes interlacing yarn(s) 25 to form a wall 12, 12′ having an inner surface 21, 21′ and an outer surface 29, 29′ extending between opposite ends 19, 20; 19′, 20′. Further, bonding a coating 27 of elastomeric material to the entirety of the outer surface 29, 29′ and forming an indicia 28 extending radially inwardly into an outer surface 30 of the coating 27 to provide the indicia 28 with a depth (d) so as to avoid being easily worn away.
The method can further include forming the indicia 28 so it does not extend through an entire thickness (t) of the coating 27, such that the depth d is less than the thickness t so as to avoid exposing the underlying outer surface 29, 29′ of the interlaced yarn(s) 25.
The method can further include providing the elastomeric material of the coating 27 as silicone or a silicone-based material.
The method can further include interlacing the yarn(s) 25 via one of a weaving, braiding or knitting process.
The method can further include forming the indicia 28 with a laser.
Depending on the application needs, the wall 12, 12′ can be constructed having any suitable size, including length and diameter. If the wall 12′ is formed as a self-wrapping wall, at least some of the weft-wise, circumferentially extending yarn(s) 25, whether multifilament and/or monofilament, can be provided as any suitable heat-settable polymeric material, such as polyphenylene sulfide (PPS) or polyethyleneterephthalate (PET), for example.
Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that the invention may be practiced otherwise than as specifically described, and that the scope of the invention is defined by any ultimately allowed claims. In particular, all features of all claims and of all embodiments can be combined with each other, as long as they do not contradict each other.
