DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) The double-sided squeegee device of the present invention is shown throughout the several views of the drawings and is generally indicated as 10. The squeegee device 10 includes a selection of squeegee card components 20 formed of a rubber composition as a one-piece, unitary body. The selection of squeegee card components 20 are provided in varying degrees of hardness (i.e., durometer) throughout a range of durometers. Each squeegee card component 20 includes a blade portion 22 with a blade edge 24 (referred to hereinafter as the “working edge”). The working edge 24 may be of a variety of different configurations (e.g., straight, curved, V-shaped), as shown throughout the several views of the drawings. As seen in the drawings, the opposite side faces of the blade portion 22 are tapered towards the working edge 24 so that the thinnest part of the blade portion 22 is at the working edge 24. In each of the embodiments, the working edge 24 of the squeegee card component 20 may be any degree of hardness throughout a selected range of durometers, according to the specific material composition and durometer of the squeegee card component 20. Thus, the working edge 24 may be more stiff on one extreme, or very soft and flexible on the other extreme. The squeegee card component 20, including the working edge 24, may be provided throughout a range of durometers of at least eight different degrees of hardness, and possibly as much as twelve to fourteen degrees of hardness (i.e., durometers). As noted above, the working edge 24 may be either straight, curved, V-shaped or other configurations. FIGS. 1-5 illustrate examples wherein both squeegee card components 20 have a straight working edge 24 of the same length (e.g., four inches). Alternatively, as seen in FIGS. 6-8, at least one of the squeegee card components 20 may be provided with a straight edge that is shorter in length (e.g., three inches). As seen in FIGS. 1-3, the squeegee card components 20 that have a straight working edge 24 are further provided with rounded corners 29 to prevent scratching or cutting the film material when using the squeegee device 10 to apply the film material to a surface.

(12) Each of the squeegee card components 20, 20A, 20B and 20C shown throughout the several views of the drawings further includes an attachment portion 30 that is structured for cooperating, sliding and interlocked attachment with the attachment portion of another select one of the squeegee card components 20-20C. The attachment portion 30 on each of the squeegee card components includes a cylindrical wall 32 that surrounds a tubular channel 34 extending from one side edge of the card 26-26C to the opposite side edge of the squeegee card component 28-28C. The tubular channel 34 is open at opposite ends and all the way through its length, with the surrounding cylindrical wall 32 having a consistent cross sectional configuration from one end to the opposite end so that the tubular channel 34 is of uniform dimension from one open end to the opposite open end. The cylindrical wall 32 includes an open gap 36 extending from one side edge 26-26C of the particular squeegee card component 20-20C to the opposite side edge 28-28C of the particular squeegee card component. The open gap 36 communicates with the open tubular channel 34. An exterior surface of the cylindrical wall 32 is textured to provide a grip. As seen throughout the several views of the drawings, one embodiment of the textured surface is an arrangement of parallel ridges that extend from one side edge 26-26C of the particular squeegee card component 20-20C to the opposite side edge 28-28C. The closely spaced parallel ridges providing the textured surface 38 promote ease of gripping of the double-sided squeegee card device 10, particularly when using the double-sided squeegee card device 10 for wet applications of film materials to surfaces.

(13) The attachment portion 30 on each of the squeegee card components 20-20C further includes a wing that is integrally formed with and extends from the cylindrical wall 32 on one side of the open gap 36. The wing 40 terminates at a distal edge that is provided with an enlarged rail 42. The enlarged rail 42 extends along the entire length of the distal edge of the wing 40, as clearly illustrated in FIG. 2. The enlarged rail 42 on one squeegee card component is specifically sized, structured and configured for sliding and fitted receipt within the tubular channel 34 of the attachment portion 30 of another selected squeegee card component, wherein each squeegee card component includes a rail 42 that is received within the tubular channel 34 of the other squeegee card component, with the open gap 36 in the cylindrical wall 32 permitting passage of the wing 40 of the other squeegee card component therethrough. FIGS. 2-4 illustrate a sequence of attachment of one squeegee card component 20 to another selected squeegee card component 20. Specifically the rail 42 of each squeegee card component is aligned with the open end of the tubular channel 34 of the other squeegee card component and then the one squeegee card component is moved in the direction of the arrow as seen in FIG. 2 until the rail 42 of each squeegee card component is received within the aligned tubular channel 34 of the other squeegee card component. Thereafter, the one squeegee card component 20 is continually moved in the direction of the arrow as shown in FIG. 3 as the rails 42 slide within the corresponding tubular channels 34 until the holes 48 formed through the wing on one squeegee card component are aligned with the holes 48 on the other squeegee card component as seen in FIG. 4. Referring to FIG. 2, the inner facing surface of the wing 40 of each squeegee card component 20-20C is further provided with a bump 44 and a detent 46. When the two squeegee card components are moved into the aligned operative position, as seen in FIG. 4, the bump 44 on one of the squeegee card components is received within the detent 46 on the opposing wing of the other squeegee card component, so that bump 44 on each squeegee card component is received within the correspondingly aligned detent 46, thereby discouraging lateral sliding movement of one squeegee card component relative to the other without applying significant force, while also indicated to the user that the two squeegee card components are interlocked in the properly aligned and operative position.

(14) Referring to FIG. 7, two different squeegee card components 20A and 20B are shown attached to one another to provide two different shaped working edges 24A and 24B, which may be of the same or a different durometer. The squeegee card component 20A has a straight working edge 24A that may be shorter in length compared to the straight working edge 24 on squeegee card component 20, shown in FIGS. 1-5. The straight working edge 24A of squeegee card component 20A may be, for example, three inches in length. The opposite side edges 26A and 28A are slanted or converged towards one another moving from the attachment portion 30 to the working edge 24A, as clearly seen in FIGS. 6-8. In FIG. 7, the squeegee card component 20A is shown attached to another squeegee card component 20B having a V-shaped working edge 24B. Squeegee card component 24B has opposite side edges 26B and 28B. Additionally, the blade portion 22B of squeegee card component 20B is provided with fingers 60 having an increased thickness relative to the working edge 24B. The fingers 60 taper in thickness along areas as indicated by the lines 62 until they reach a minimum thickness at web areas 64 between the fingers 60 and on the opposite outboard sides of the fingers 60. The fingers 60 provide strength to the blade portion 22B, while the webbed areas 64 between the fingers 60 provide increased flexibility of the blade portion 22B when using the squeegee card component 20B, and particularly when applying pressure of the working edge 24B against a surface upon which a film material is being applied.

(15) FIG. 6 shows yet another squeegee card component 20C attached to squeegee card component 20A. Squeegee card component 20C includes a curved working edge 24C extending from one side edge 26C to the opposite side edge 28C. Similar to the structure of the squeegee card component 20B in FIG. 7, the squeegee card component 20C in FIG. 6 includes fingers 60 on the blade portion 22C with webbed areas 64 between the fingers and a decreasing thickness of material surrounding the fingers 62. Similar to the squeegee card component 20B as described in FIG. 7, the fingers 60 on squeegee card component 20C and web areas 64 provide for flexibility of the working edge 24C, while maintaining strength and rigidity of the blade portion 22C. This particular working edge 24C, having a curved configuration, is particularly useful when applying film materials to tight concave surfaces, such as the dish-shaped surfaces surrounding exterior door handles on an automobile. More particularly, the squeegee card component 20C with the curved working edge 24C is particularly useful to apply wraps to the exterior surface of automobiles within tight concave surface areas, such as the areas surrounding the exterior door handles.

Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
