The present disclosure relates, in general, to sporting attire, and more particularly to socks to be warn in conjunction with waders or tall waterproof boots.
Fishermen utilize waders of the chest or hip design when fishing in shallow water. These are generally a contiguous, thin, waterproof, polymer set of leggings. Generally, the wearer inserts his socked feet and clothed legs into the waders. Since the fisherman is often in the water in waders for hours, there is a need to insulate the fisherman's legs and feet from the large heat loss through the waders to the body of water. Also there is often water introduced into the wader socks' top openings. Elimination of this uncomfortable element is desirable. Additionally, the bottom of the lake or river bed may have jagged rocks that put pressure points on the soles of the wearer. Padding is desirable. Sock creep is a phenomenon that occurs when the sock and the foot are not well mated by design. As the wearer walks, the sock slides down the leg toward the end of the foot where it bunches up and makes walking uncomfortable. Lastly, people's feet differ greatly in size and shape. Since waders are a niche, it is desirable to have a sock that fits a range of feet sizes and shapes.
Henceforth, an improved undergarment for use with a pair of waders that maximizes the amount of heat retained, is easy to insert into waders, fits a plethora of feet sizes and shapes, cushions the sole, and eliminates creep would fulfill a long felt need in the fishing industry. This new invention utilizes and combines known and new technologies in a unique and novel configuration to overcome the aforementioned problems and accomplish this.
In accordance with various embodiments, a wader sock is provided.
In one aspect, a rollable polymer sock having anti-creep device affixed to the outer face thereof.
In another aspect, a wader sock is provided, capable of elimination or ejecting water that has entered the sock from the top.

When reference is made to a reference numeral without specification to an existing sub-label, it is intended to refer to all such multiple similar components.
While various aspects and features of certain embodiments have been summarized above, the following detailed description illustrates a few exemplary embodiments in further detail to enable one skilled in the art to practice such embodiments. The described examples are provided for illustrative purposes and are not intended to limit the scope of the invention.
In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the described embodiments. It will be apparent to one skilled in the art, however, that other embodiments of the present invention may be practiced without some of these specific details. While various features are ascribed to different embodiments, it should be appreciated that the features described with respect to one embodiment may be incorporated with other embodiments as well. By the same token, however, no single feature or features of any described embodiment should be considered essential to every embodiment of the invention, as other embodiments of the invention may omit such features.
Unless otherwise indicated, all numbers herein used to express quantities, dimensions, and so forth, should be understood as being modified in all instances by the term “about.” In this application, the use of the singular includes the plural unless specifically stated otherwise, and use of the terms “and” and “or” means “and/or” unless otherwise indicated. Moreover, the use of the term “including,” as well as other forms, such as “includes” and “included,” should be considered non-exclusive. Also, terms such as “element” or “component” encompass both elements and components comprising one unit and elements and components that comprise more than one unit, unless specifically stated otherwise.
As used herein, the term “waterproof” is equivalent with “water resistant” with respect to the fabric of construction. Technically, neoprene is not 100% impervious to water and water can penetrate through neoprene to a very small degree, however for the function of this material in a chest or hip wader, the differences are irrelevant.
The present invention relates to a novel design for a pair of socks to be used in conjunction with hip or chest waders as would be used by a fisherman. Their design adds to the comfort of the wearer by providing four elements that heretofore have not been incorporated into wader socks. They are: cushioning for comfort, porous water ejection ports on the sole and up the back of the calf to eliminate water that has entered the sock, a thermal barrier to keep the feet and legs warm and a top hook to prevent the wader sock from creeping down into the waders.
The fabric used in the construction of the wader sock 2 is commonly and commercially known as Neoprene or polychloroprene. It was invented by DuPont® in 1930, and represents a family of synthetic rubbers that are produced by polymerization of chlorine so as to encapsulate millions of tiny gas bubbles in the material. This provides a for a thickened, waterproof material that is elastically deformable in compression, that resists the transfer of heat through it, that exhibits good chemical stability and maintains flexibility over a wide temperature range. Because neoprene abrades, chips and tears easily, there is usually an associated sheer outer covering of a thin woven polymer fabric that is glued onto both sides of the underlying neoprene. This fabric must have a denier or pressure resistance rating that will allow water to pass through it when under the pressure of a human foot walking in a boot. This is a range of approximate 50 to 150 denier and a 250 to 1250 mm pressure resistance.
This fabric was chosen because it is flexible enough to be stretched over the foot and leg to return to a form fitting configuration on the wearer. This tight form fit keeps water out of the wader sock, which is crucial to the user's comfort. Not only does water in the wader sock 2 take away body heat, it makes walking about a “sloshing mess”.
Looking at
There are four different types of fabric used in the wader sock 2. The top panel 6, left side panel 8, right side panel 10 and upper cuff 12 are all made from a minimum 3 mm thick neoprene fabric having a sheer polymer fabric adhesively affixed to the two outer faces of the central neoprene 12 layer. This polymer fabric outer layer in the preferred embodiment is polyester or nylon optionally with spandex or elastine mixed in to increase flexibility and 2 way stretch. In an alternate embodiment, the fabric outer layers may be what is known generally as “scuba fabric” which is a spun polyester with spandex or lycra knitted simultaneously together in what is known as a double knit.
The sole and heel cup panel 4 are made from the same materials as the remainder of the panels except the sole and heel cup panel has a repeating pattern of orifices formed through the central neoprene layer of the fabric, but not through the outer sheer fabric layers. The denier of the sheer fabric layers is large enough to allow the passage of water there through this perforated neoprene when under a slight pressure. (As is encountered with the pumping action of the foot when walking.)
The interior fold ring 14 is made of an elastic polymer strip that generally has one way elongation under tension. Lastly, the upper attachment clip is a resilient hook 16 (preferably made of metal or a rigid polymer) sewn onto a rectangular section of nylon webbing 20 affixed to or adjacent the top edge of the upper cuff 12.
The wader sock 2 has a lower sock 24 and an upper sock 26 joined at the horizontal interface 28. The sole and heel cup panel 4, top panel 6, left side panel 8 and right side panel 10 form the lower sock 24 and are shaped such that when connected, will form the contour of a lower portion of a human leg and foot. The upper sock 26 has a tubular configuration. Looking at FIG it can be seen that the sole and heel cup panel 4, is a linear strip extending from the tip of the wader sock 22 to the interface of the upper cuff 12 at the interior fold ring 14. It thus places the most compressible neoprene along the bottom of the foot and up the calf. These are the two areas that the leg and foot contact the wader sock 2 with the most pressure as the wearer moves about. Since these are the porous perforated neoprene sections, downward pressure generated between the arch of the foot and the bottom of the waders pump the water out of the sock. The outer sheer fabric bonded to the neoprene has a fine denier that resists water not under pressure from returning into the sock. In this manner, the user's feet are kept isolated from water that has entered the wader sock 2. A low friction coating may optionally be applied to the outer face of the wader sock 2 to ease the forces of insertion into tight waders or boots.
The sole and heel cup panel 4 and the top panel 6 are the longest panels extending from the wader sock front tip 22 to the upper cuff 12. The leading edges of these panels from the toe area to mid foot 35, are joined together, preferably by flat lock or blind stitching method of sewing engagement. Disposed between these panels beginning at mid foot 35 where the sole and heel cup panel 4 and the top panel 6 diverge and continue to the upper cuff 12, are the intermediary, shorter, mirror image, L shaped left side and right side panels 8 and 10. These are also joined to the sole and heel cup panel 4 and the top panel 6, preferably by a flat lock or blind stitching method of sewing engagement. The top edge of these joined four panels form a ring that is joined to a similarly sized ring on the upper cuff 12, by the interior fold ring 14. The interior fold ring 14 spans the circular edge of the lower end of the upper sock 26 and the similarly sized circular edge of the top end of the lower sock 24, extending down for a short distance onto their interior faces adjacent their edges. The interior fold ring 14 thus connects the bottom perimeter of the upper cuff 12 and the top perimeter of the joined sole and heel cup panel 4, top panel 6, left side panel 8 and right side panel 10. (This is best seen in
The method of joining the panels, upper cuff and ring makes a difference in how well they perform, especially with respect to waterproofing. In the preferred embodiment, the sole and heel cup panel 4, top panel 6, left side panel 8, and right side panel 10 are connected with a flat lock stitch wherein the edges of the neoprene are butted or overlapped together, and two or four needles punch all the way through the material to make a flat, interlocking thread pattern that is very strong and comfortable against the skin. The many holes created do allow considerable water penetration. This may be waterproofed by using an adhesive waterproof fabric tape that is glued or hot meted onto the fabric or through the application of a liquid seam sealant as is well known in the industry. The two edges of the upper cuff 12 (
Alternately, the panels may be joined with a blind stitch where the edges of the material are first glued together then the seam stitched together with an overlapping stitch from a special sewing machine with a curved needle. Here the needle only penetrates the face fabric on one side of the material. This very strong seam that is waterproof but requires a minimum of a 3 mm thick neoprene.
There is a different type of stitching used to connect the lower sock 24 and the upper sock 26. The upper fold ring 14 is single needle stitched 30 in two rings about the peripheral edges of the lower sock 24 and upper sock 26 so as to form a contiguous wader sock 2. Because of the elevation that this stitching occurs water intrusion through any needle holes is not an issue. The upper sock 26 primarily is only for insulation and splash protection and is never immersed in water as the sole of the lower sock 24 may be.
In use, the wader sock 2 may be worn full stretched as in
When a conventional wader sock is installed in a pair of chest or hip waders and water enters the sock, the wearer is stuck with that sloshing mess in his sock until he empties the sick. With this improved wader sock 2, as the user moves around this water is simultaneously pumped out of the wader sock 2 in the sole, the heel cup and the calf regions by the walking pressure the foot places on the porous neoprene. Hence the reason for the linear sole and heel cup panel that extends from the wader sock front tip 22 of the wader sock 2 to the upper fold ring 14. (
