   This application is a continuation-in-art of U.S. patent application Ser. No. 09/874,940, filed Jun. 4, 2001. 

   BACKGROUND 
   1. Field of the System 
   The present invention relates to grips for hand railings or other hand support systems. More specifically, the present invention relates to grips which are releasably adhered to railings or other hand support systems. 
   2. Prior Art 
   Hand railings are in use throughout the world to assist in human activity such as standing, sitting down, ascending and descending a stairway, entering or exiting a moving vehicle, walking, etc. Maintaining a secure, comfortable grip is extremely important when operating or using various hand-held apparatuses or, more importantly, simply for safety purposes when grasping any type of railing. Bare railings are used for hand supports by users, standing, or sitting, or while entering or exiting a vehicle. Bare railings, whether they are constructed from any type of metal, plastic, wood, glass, concrete or composite material can be slippery, or coarse and inconvenient to hold onto with bare hands. Furthermore, uncovered railings located in moving vehicles such as subway train cars, light rail transit cars, transit buses, trams, street cars, trolley cars, recreational vehicles, etc., are unsafe when the vehicle is in motion and especially when turning. Typically, such railings are extruded shapes, such as a circular tube or another similar shape made for the human hand to grasp. Additionally, these railings are usually constructed from durable metal, such as stainless steel, but may also be constructed from wood or various other substances. 
   Such typical hand railings, however, do not provide a positive gripping surface, which would still further assist in the corresponding human activity associated with the hand railing. Some of the present gripping devices include molded plastic cylindrical grips which are installed and include cross-sectional sections designed to fit the human hand as in U.S. Pat. No. 5,584,096 to Auroura, rigid hand railings having a plurality of finger sized indentations, U.S. Pat. No. 5,190,267 to Schmitt, et al. and rail covering systems for outdoor decks as in U.S. Pat. No. 6,062,519 to Baldassarre. Still other gripping devices include removable foam grips that are wrapped around a bar each time a user wishes to use a bar as in U.S. Pat. No. 5,775,756 to Rozenich. This type of grip is typically used for weightlifting equipment. The grips to date involve either railings with built in grips or grips that are, for the most part, permanently attached to the railings, while other grips are not attached at all, rather they are easily removed and transferred from bar to bar. 
   To date, no grips have been designed which will conform to any railing surface or shape and which are releasably attachable to such railing surface. Hence, there is a need for a grip which will conform to any railing type and which will attach to any railing surface regardless of the type of surface or type of material used as the grip and a grip which is releasably attachable to the railing. 
   Further, to date no grips have been designed that have safety features incorporated into the grip, which will enable a user to use the grip to achieve safety even in the most detrimental conditions. Hence, there is a need for a grip which has textured surfaces to generate additional friction for gripping, some of which are readable to vision impaired persons, illuminated surfaces to guide the user to safety, sound emitting technology incorporated within the grip to guide the user to safety, and anti-bacterial agents to prevent the spread of disease. 
   SUMMARY OF THE INVENTION 
   The present invention is a method, system and device for providing a secure, resilient gripping surface on a railing or other hand support system. The grip of the present invention is designed to provide a secure, resilient gripping surface on any railing or hand support system surface that is grasped by a hand. The grip is preferably utilized on a railing or other hand support system. However, it is readily apparent that the grip could also be used on other structures, such as support poles and beams, etc. 
   In one aspect of the present invention, a flexible gripping pad is provided which is easily secured to a railing or hand support system by wrapping the grip around the railing or hand support system. The grip may fully cover the railing, or it may be artfully wrapped or it may be partially or fully folded. The grip of this invention will provide a comfortable, resilient gripping surface which will enhance the safety of a railing or hand support system by preventing slipping, hand abrasions or other dangers associated with railings or hand support systems. 
   In one aspect, the grip of the present invention comprises a skin layer having a top surface and a bottom surface, and a 4-way stretchable material layer having a top surface and a bottom surface. The top surface of the 4-way stretchable material layer is permanently adhered to the bottom surface of the skin layer. The bottom surface of the 4-way stretchable material layer is releasably attached to the railing or hand support system. 
   The skin layer may be formed from any material which will provide a safe and secure gripping surface. Some examples of possible skin materials include expanded vinyl, which is vinyl with a layer of foam that imparts a soft, textured feel, leather, plastic sheeting, plastic roll stock, any type of foam product, polyurethane, urethane, woven fabrics, rubber material and foil material. If a vinyl material is used, the vinyl may be supported or unsupported. Similarly, the 4-way stretchable material may comprise any material that can be simultaneously stretched in four directions, such as a polyester material. 
   In yet another aspect of the present invention, the skin layer of the grip of the present invention has a luminescent quality. The luminescent skin layer glows in the dark to provide additional safety in cases of an emergency. 
   In another embodiment, the grip of the present invention comprises a skin layer having a top surface and a bottom surface, and a backing layer having a top surface and a bottom surface. The top surface of the backing layer is permanently adhered to the bottom surface of the skin layer. Furthermore, the backing layer is permanently attached to a 4-way stretchable material layer with a stretchable top surface and a stretchable bottom surface. The bottom surface of the 4-way stretchable material layer is releasably attached to the railing or hand support system. 
   The grip of the present invention may have tapered edges on its lengthwise sides so that when the grip is spirally wrapped around a railing or other hand support system and the edges overlap, the thickness of the grip remains constant. As an alternative to wrapping the grip such that the edges overlap, the grip may be wrapped so that the edges do not overlap, thus providing additional friction for the user. 
   One method of manufacturing the grip of the present invention comprises providing a skin layer which has a top surface for gripping and a bottom surface to which a permanent adhesive applied. Next, a 4-way stretchable material that has a top surface and a bottom surface is permanently attached to the bottom surface of the skin layer. Finally, the bottom surface of the 4-way stretchable material is releasably adhered to the railing. 
   Another method of manufacturing the grip of the present invention comprises providing a skin layer which has a top surface for gripping and a bottom surface to which a permanent adhesive is applied. Next, a backing layer is provided, which has a top surface and a bottom surface. The top surface of the backing layer is adhered to the bottom surface of the skin layer. Next, a 4-way stretchable material layer with a top surface and a bottom surface is permanently attached to the backing layer by adhering the backing layer bottom surface to the 4-way stretchable layer top surface. Finally, the 4-way stretchable material is releasably adhered to the railing. 
   The system of the present invention is designed for providing a secure, safe, releasably attachable grip on a railing. The system comprises a grip having a 4-way stretchable layer with an inner surface and an outer surface and a skin layer with an inner surface and an outer surface, the inner surface of the skin layer is adhered to the outer surface of the 4-way stretchable layer. The inner surface of the 4-way stretchable layer is releasably adhered to the railing. 
   Another system of the present invention is also designed for providing a secure, safe, releasably attachable grip on a railing. The system comprises a grip having a backing layer with an inner surface and an outer surface and a skin layer with an inner surface and an outer surface, the inner surface of the skin layer is adhered to the outer surface of the backing layer. The bottom surface of the backing layer is permanently adhered to a 4-way stretchable layer with an inner surface and an outer surface. The inner surface of the 4-way stretchable layer is releasably adhered to the railing. 
   As set forth above, the grip of the present invention may have tapered edges on its lengthwise sides so that when the grip is wrapped around a railing or other hand support system and the edges overlap, the thickness of the grip remains constant. As an alternative to wrapping the grip such that the edges overlap, the grip may be wrapped so that the edges do not overlap, thus providing additional friction for the user. 
   One method of placing the grip of the present invention on the railing comprises providing a railing and wrapping the tapered edge grip of the present invention spirally around the railing such that the tapered edges of the grip overlap. The length of the railing may be fully covered by the grip such that the thickness of the grip remains constant or, in the alternative, the edges may not overlap to provide additional friction for the user. 
   Another method of placing the grip of the present invention on a railing comprises providing a railing having a length and alignment targets in a parallel line along its length. Next, placing the grip so that the center lengthwise axis of the grip is centered on the axis parallel to the length of the railing. The grip of the present invention has alignment targets disposed along an axis parallel to the lengthwise edge of the grip and the grip folds around the railing such that the alignment targets of the grip align with the alignment targets of the railing and the edges of the grip abut when folded around the railing. 
   The grip of this invention will provide a positive gripping surface for any type of railing using any type of material as a grip and provide a safe, uniform gripping surface for the length of the railing&#39;s surface. Moreover, there is a need for a method of manufacturing for grips and a system for providing grips which are releasably adhered to a railing or hand support system. Finally, there is a need for a method of placing the grip of the present invention on to a railing or other hand support system.

   DETAILED DESCRIPTION 
     FIG. 1  discloses grip  100  for use on a railing or hand support system. Grip  100  has a skin layer  104  and a 4-way stretchable layer  112 . Skin layer  104  has a top surface  102  which provides a comfortable, secure and safe gripping surface. Skin layer  104  can be formed from a variety of materials. Examples of such materials include expanded vinyl, which is vinyl with a layer of foam that imparts a soft, textured feel, leather, plastic sheeting, plastic roll stock, any type of foam product, polyurethane, urethane, woven fabrics, rubber material, foil material or any other material which could act as a covering to a hand support system. If skin layer  104  is formed from expanded vinyl, the vinyl surface may be smooth or textured. In addition, if a vinyl material is used, the vinyl may be supported or unsupported. In yet another aspect of the present invention, skin layer  104  of grip  100  of the present invention has a luminescent quality. The luminescent skin layer glows in the dark to provide additional safety in cases of an emergency. Any methods known in the art for creating luminescence may be used, for example some of the methods include transfer application processes, wet ink processes and sublimation ink processes. In yet another embodiment of the invention, skin layer  104  has an antibacterial agent, such as Benzothiazoline (BIT), Octylisothiazoline (OIT), Thiabendez (TBZ), or zinc pyrithionoxide (ZPT), added to the skin layer of the grip. The antibacterial agent may be added in different concentrations depending on where the grip is used. 
   Four-way stretchable layer  112  has top surface  110  and a bottom surface  114 , such that top surface  110  of 4-way stretchable layer  112  conforms to and is permanently affixed to bottom surface  106  of skin layer  104 . 4-way stretchable layer  112  may be comprised of any material that can simultaneously stretch in four directions such as a polyester material. Bottom surface  114  of 4-way stretchable layer  112  is releasably attached to the railing or hand support system by a layer of releasable adhesive  116 . Releasable adhesive  116  completely covers from edge to edge and is affixed to 4-way stretchable layer  112  and provides releasable adhesion to the railing or hand support system. Releasable adhesive  116  provides secure adhesion to the railing or hand support system but may be removed with a minimal amount of effort by peeling grip  100  off the railing or hand support system.

Textured surface  802  can be formed from a variety of materials. For instance, hard rubber, soft crayon rubber, plastics of any type, woven material and any other material known in the art suitable for this purpose. In addition, patterns, such as Braille symbols for the vision impaired or safety instructions can be molded into the surface of the grip.  FIG. 16  illustrates the use of Braille symbols  806  on a grip  804 . 
   An additional property of the textured grip is insulation effect. The thickness of the textured surface  802  acts as a natural insulator. This property makes the railing usable in extremely hot or cold weather conditions. In addition, fire retardants such as bromine based retardants, phosphate based retardants, or Tetrabromobisphenol A (TBBPA) epoxy can be added to the textured surface making the grip  800  fire resistant and safer for human use. 
     FIG. 15  shows the grip  900  of the present invention having sound emitting means  902  incorporated within the grip. As is well known to those skilled in the art of sound technology, sound emitting means  902  can be activated by using a pressure sensitive switch which will transmit a signal to a preprogrammed microchip. Once the sound emitting means is activated, the speakers that emit the sound are activated. In one embodiment, each sound unit is independently powered by battery pack. In another embodiment, a solar switch may be used to turn on the sound emitting means. In this embodiment, when the lights are turned off, a signal is sent to a preprogrammed microchip that turns on the sound emitting means.
