This application is a continuation of U.S. application Ser. No. 29/259,909, filed May 16, 2006, entitled SHEET MATERIAL OF INDEFINITE SIZE AND SHAPE FOR USE AS A GRIPPING SURFACE, and claims the benefit of Australian Patent Application Serial No. 2006905711, filed Oct. 13, 2006, entitled A DECK GRIP, each of which is hereby incorporated by reference.
BACKGROUND OF THE INVENTIONThis invention relates to a deck grip which in use is applied to a surface to enable adequate gripping of that surface. The deck grip may be formed as an integral part of the surface or alternatively may be formed from a material which can be applied to a surface. A particular application of the invention relates to a deck grip which can be utilized with sports boards. Throughout the specification and claims the term “sports board” will be taken as including surf boards, wave boards, wakeboards, skateboards and the like.
Sports boards of the form referred to above are provided and in particular those that are used in aquatic situations are provided with a smooth surface to enhance their performance however, the presence of the smooth surface creates a problem for the occupants who usually have bare feet when thy are using the sports board. It has been a well established practice for the users to apply a wax to the surface of the board which is to be used. In more recent times the practice has been adopted of providing a deck grip over the surface of the board which is to bear the feet of the occupant in use. Such deck grips are most often in the form of a panel formed of a suitable cushioning material which will resiliently conform to the sole of the feet of the user while enhancing the grip of the feet to the surface. A difficulty experienced by users of such deck grips is that the degree of grip is not as good as they would like and they lose a sense of the “feel” of the board which creates a problem in maintaining a control of the board. The capacity of the occupant to have good “feel” of the sports board becomes very important in competition.
Throughout the specification and claims, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.

In another aspect, the present invention provides a deck grip comprising a base and rows of upwardly directed spaced protrusions extending from the base, wherein the alternate rows of protrusions are generally of a greater height than the rows therebetween, the protrusions being formed of a resiliently compressible material.
The rows of protrusions are preferably spaced from each other with a space located therebetween. Each row of protrusions preferably comprises individual protrusions spaced from each other with a space located therebetween. Each row of protrusions comprises spaced identical protrusions, which are preferably regularly spaced. The protrusions in one row can be generally aligned with the protrusions in an adjacent row or generally offset therefrom. The invention will be more fully understood in the light of the following description of several specific embodiments.
The description is made with reference to the accompanying drawings of which:
Each of the embodiments are directed to a deck grip which in use is to be applied to the upper surface of a surfboard in the region which is to be occupied by at least a foot of the occupant, typically the occupant's back or trailing foot. As shown at
In the case of the first embodiment shown at
The orientation of the deck grip 13 and thus the ridges on a surfboard 11 will depend on a user's preferred orientation. Typically, the deck grip will be attached such that the ridges extend across the surfboard. The user's trailing foot in use generally extends across the rear end of the surfboard 11 and thus the ridges can be substantially aligned with the user's trailing foot in use. Each of the protrusions has a generally prismatic configuration. As shown in
In addition the upper face of the upper cubic portions 23 of the second protrusions 15b which are of the greater height are formed with a lateral groove 27 to further enhance the gripping action.
The deck grip according to the first embodiment is formed as a sheet from which suitably shaped panels can be cut for application to the sports board. The under-face of the sheet has an adhesive applied to it which is overlaid by a removable membrane. In use a panel of the desired configuration is cut out from the sheet and the membrane is removed from the adhesive laden under-face and the panel is applied to the sports board in the region to be occupied by the occupant's feet in use. If desired a number of discrete panels can be applied to the deck of the sports board according to desires of the user.
The deck grip according to the first embodiment as described above provides a contoured upper surface which serves to enhance the gripping of the deck grip by the feet of the user. Furthermore, by providing portions having a lower profile the soles of the feet of the user are bought into a closer spaced relation to the body of the board. This reduction in height which serves to improve the “feel” of the board as sensed by the user who is then able to have a better sense of the movement of the board to provide for a better control of the board. However the presence of the higher portions of the deck grip as provided by the row of higher protrusions provide a courser level of traction/grip for the feet. The multiple functions of the deck grip of the first embodiment in providing an improved traction and a better “feel” while ensuring that there is adequate traction/grip provides the user with significant advantages particularly when in competition.
The second embodiment of the invention as illustrated at
The third embodiment of the invention as illustrated at
The fourth embodiment as shown at
According to a further embodiment of the invention which can apply to each of the previous embodiments the protrusions of each row may be of alternating heights whereby each row comprises a set of first protrusions 15A and second protrusions 15B of the respective embodiment with one form of protrusion being located between a pair of the other form of protrusions.
Other alternative embodiments are also possible. For example, the rows of protrusions can be continuous to form rib-like protrusions extending across the surface of the deck grip. The ridges can be generally linear or convoluted. The ridges can also be of differing height along their length.
It should be appreciated that the scope of the present invention need not be limited to the particular scope of the embodiments described above. In particular the invention can be utilized in association with any form of sports board including surfboards, sailboards, wave boards, skateboards or the like. In addition the deck grip could be used in association with other forms of water craft and may be in the form of a of sheet material which is to applied over a deck or may be formed into the deck.
