DETAILED DESCRIPTION OF THE INVENTION

(12) The inventor provides a body pad apparatus to limit slip, to limit movement, to pad pressure points, and to fill spaces of and between the user's body and an externally worn apparatus such as a sports harness used in kiteboarding or windsurfing, such as climbing or safety harnesses, or such as personal flotation devices used in water sports. Components of a harness or personal flotation device for which the present invention may be applied may include, but are not limited to, surfaces, belts, plates, straps, pads, buckles, and fasteners. The present invention could ideally be worn around the waist, torso, or leg, in between the user's body and an external apparatus. The present invention is described in enabling detail in the following examples, which may represent more than one embodiment of the present invention.

(13) Components of the Invention:

(14) FIG. 1a is, in this example, a front view of an embodiment of the apparatus by itself, as it would appear when worn by user. Number 101 represents a textured, high friction surface material on the outward-facing side of the apparatus. Number 102 represents a textured, high friction surface material on the inward-facing side of the apparatus. Number 103 represents the point of connection where low-profile attachments on either ends of the apparatus could meet to secure the ends together. In this embodiment, the attachments at the ends would keep the material from loosening after it has been pulled tight around the user's body. Number 104 represents a possible shape of cut for the material, on one side of the apparatus, to create a contour to allow the apparatus to better fit the user's body. Number 105 represents a possible shape of cut for the material on the opposite side of the apparatus, to create a contour to allow the apparatus to better fit the user's body. FIG. 1b, in this example, represents a side view of an embodiment of the apparatus. Number 106 represents the contour of the material as it is pressed or drawn tight against the user's body. In this example, drawing the material of the apparatus tight around the user would create material stretch in the apparatus and conform tightly to curves of the user's body. In this example, the attachments represented by 103 would hold the tension of the material stretch to keep the apparatus in shape of FIG. 1b around the user's body. FIG. 1c, in this example, represents a rear view of an embodiment of the present invention, where number 101 represents the outward-facing, textured, high friction surface material.

(15) FIG. 2a, in this example, represents the embodiment of the present invention, as illustrated in FIG. 1a, worn on the body of a user around the waist. The present invention may also be worn at other locations on the body, such as around the torso, or hips. Similar embodiments of the present invention may be worn at other locations on the body, such as a leg, where a harness or personal flotation device may contact the user's body. Number 201 in FIG. 2b represents a “waist style” kiteboard or windsurf harness worn over the embodiment of the invention represented in FIG. 2a. FIG. 2b 100 represents one embodiment of the present invention as it would be used between a user's body and an external harness device.

(16) FIG. 3a, in this example, represents the embodiment of the present invention of FIG. 1a, as it would appear laid flat, unadorned by a user. Number 301 represents a view of the outward-facing textured high friction surface material of number 101 as it would appear when the device is laid flat. Number 303 represents a possible nylon or polyester edging material affixed around the outer perimeter of the present invention. Number 302 represents an outward-facing section of “Velcro” style loop material that would give a range of attachment surface locations for placement of the opposing, inward-facing, hook attachment represented in FIG. 4a number 402. FIG. 3b number 304, in this example, represents a profile view of the length of the present invention represented in FIG. 3a. In FIG. 3b, in this example, the present invention can be seen as a long thin section of material.

(17) In FIG. 4a, in this example, number 401 represents the inward-facing surface of the embodiment of the present invention of FIG. 1a, as it would appear laid flat, unadorned by a user. Number 402 represents the “Velcro” style hook that could attach to various positions on the opposing loop surface of number 302.

(18) In FIG. 5a number 500, in this example, represents an askew view of a possible cross section of material construction for the present invention. Number 501 represents the textured high friction surface material represented in FIG. 1a number 101. On the opposite side of the material, number 502 represents the textured high friction surface material represented in FIG. 1a number 102. In this embodiment of the present invention both the inward-facing surface number 102, and the outward-facing surface number 101 could be made of the same material. In this example, the embodiment of the present invention could use a “shark skin” style neoprene (chloroprene rubber) in which the surface is patterned and molded from the underlying neoprene rubber material. The underlying neoprene rubber material, in this example, is represented by number 503 and number 504. In other embodiments, number 501 and/or 502 could represent an applied embossment or high friction fabric type material that could be affixed to the underlying layers represented by number 502 and number 503. Other surface textures may work in additional embodiments. In between the neoprene rubber layers, in this example, represented by 503 and 504, could be a thin layer of stretchable material, represented by number 505, such as polyester, elastane, or nylon, to provide tensile strength at a certain stretch limit, to give tear resistance to the apparatus. FIG. 5b, in this example, is a side view of the cross-section FIG. 5a. In FIG. 5b number 501 can be seen to have a textured surface.

(19) The important factors in the design of the present invention are that the surface of the material have innately, or be made to have a high surface friction, possibly similar to USPTO Class 2 Apparel 161.3 or Class 2 Apparel 168, and that the material have some amount of stretch and pressure absorption. In one embodiment, the device may be made from a material that stretches and conforms to the user's body, such as a textured surface chloroprene rubber (neoprene) on both the inward-facing side in contact with the user's body or garments, and on the outward-facing side in contact with the harness or personal flotation device. In one embodiment, the neoprene may be three to four millimeters in thickness. Thickness of the pad apparatus could vary depending on the level of stretch and pressure absorption desired. In another embodiments, additional materials may be used for the body of the apparatus.

(20) In one embodiment, the open front ends of the present invention may be secured together, enclosing the pad around the user's body, by using a low-profile attachment device such as “Velcro” style hook and loop attachments on either side of the device ends.

(21) Hook and loop attachments may provide repeated fastening of the attachments. In one embodiment, the edges of the present invention are covered with a nylon or polyester material or similar with material stretch properties. In one embodiment, the present invention is designed to be wider at the midpoint for a contoured fit to the user's body, and tapers to become narrower at the ends near the attachment points.

(22) Process for Building the Invention:

(23) Cutting the material may be done with a razor, or scissors, or a die cut machine, or other mechanism. In one embodiment, materials are glued together using an adhesive appropriate for neoprene or nylon, or sewn together. In one embodiment, one of the open ends of the device has “Velcro” style loops on the outside of the device facing away from the user glued or sewn in place. The opposite end of the device has “Velcro” style hooks glued or sewn in place on the inside of the device facing the loops of the opposing side so that the two sides meet and join together through hook and loop attachment properties. Alternate embodiments may use different means of attaching the ends. The edges of the pad device may be covered with a nylon or polyester material that is glued on with an appropriate adhesive, or sewn on.

(24) It will be apparent to one with skill in the art that the traction pad apparatus may be provided using some or all of the mentioned features and components without departing from the spirit and scope of the present invention. It will also be apparent to the skilled artisan that the embodiments described above are specific examples of a single broader invention which may have a greater scope than any of the singular description taught. There may be many alterations made in the descriptions without departing from the spirit and scope of the present invention.
