DETAILED DESCRIPTION OF THE INVENTION

A method and apparatus for removably framing an electronic unit is disclosed. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that these specific details need not be used to practice the present invention. In other circumstances, well-known structures, materials, and processes have not been shown or described in detail in order not to unnecessarily obscure the present invention.

Referring to Fig. 1, a frontal view of the removable frame of the present invention is illustrated. The frontal view of the present invention shown in Fig. 1 illustrates the exterior surface of the panel 110, on which an ornamental covering may be applied. Such ornamental coverings may include transparent or colored paints or lacquers, wallpaper or bonded imagery, etching or carvings, or other type of conventional ornamental coverings. As shown in Fig. 1, panel 110 defines a transparent opening or aperture 115 through which a display device of an electronics unit may be viewed. Also shown in Fig. 1 is a beveled edge 120 providing better viewing of the display device of the electronics unit from various viewing angles. Panel 110 may be fabricated from a variety of conventional materials, e.g. plastic, wood, metal, fiberglass, composite material, or the like.

Fig. 2 illustrates the embodiment of Fig. 1 as viewed from an edge of panel 110. As indicated by the view shown in Fig. 2, this embodiment of the present invention represents one implementation of the present invention with a substantially flat exterior surface of panel 110.

Referring to Fig. 3, the interior surface of one embodiment of the present invention is illustrated. The inner or interior surface of this embodiment of the present invention includes a latch stop 300 fabricated into the interior surface of panel 110 and extending around the inner perimeter of panel 110. It will be apparent to those of ordinary skill in the art that latch stop 300 may extend around the entire perimeter of panel 110 or only a portion thereof. The latch stop 300 provides a means with which the panel 110 may be removably coupled to an electronics unit. This aspect of the present invention will be described in more detail in the figures that follow. Fig. 3 also shows a transparency recess provided in the interior surface of panel 110. The transparency recess 310 provides an interior surface for retaining a transparent plate between the panel 110 and an electronics unit to which the panel 110 is removably coupled. The transparent plate may be glass, plexiglass, polycarbonate, or other transparent material. Figs. 4 and 5 illustrate an embodiment of the panel 400 as removably coupled to electronics unit 420. Transparent plate 410 is retained adjacent to electronics unit 420 as captured by the transparency recess 310 of panel 400. Figs. 4 and 5 also illustrate the latch stop 430 on the interior surface of panel 400. As will be described in more detail below, latch stop 430 enables the panel 400 to be removably coupled to electronics unit 420. Referring now to Fig. 6, a cutaway view of panel 400 is illustrated. Panel 400 in this embodiment includes various components as will be described in various dimensions. It will be apparent to one of ordinary skill in the art that these dimensions can be varied depending on the size and shape of the electronics unit being framed and the ornamental characteristics desired. In Fig. 6, panel 400 includes latch stop 600. In one embodiment of the invention, latch stop 600 includes a lead-in angle illustrated in Fig. 6 as Angle B 612. The lead-in angle of latch stop 600 facilitates the coupling of latch stop 600 with a latching recess in an electronics unit. Latch stop 600 further includes a retention angle defined by Angle A 610 shown in Fig. 6. The retention angle of latch stop 600 balances the secure coupling force needed to retain the panel 400 on the electronics device with the force needed to readily remove the panel 400 from the electronics unit. It will be apparent to one of ordinary skill in the art that the lead-in angle and the retention angles of latch stop 600 can be varied depending upon the characteristics of the material from which panel 400 is fabricated and the level of force desired for engaging or removing the panel 400 to and from the electronics unit 420.

Fig. 6 also illustrates the transparency notch 602 provided on the interior surface of panel 400. As shown, in this embodiment, transparency notch 602 is a substantially rectangular notch cut into the interior surface of panel 400 to retain a transparent plate therein. It will be apparent to one of ordinary skill in the art that the particular dimensions of transparency notch 602 may be varied depending on the dimensions of the transparent plate being used and the retention characteristics desired. Fig. 6 also illustrates the beveled edge 640 on the exterior surface of panel 400. The beveled edge 640 facilitates viewing of the display device of an electronics unit through the aperture 115 of panel 400.

Referring now to Figs. 7 and 8, a cross-sectional view of the panel 400 of one embodiment of the present invention is illustrated. Fig. 7 illustrates the panel 400 as removed from electronics unit 420. As described earlier, the panel 400 of this embodiment includes latch stop 600 and transparency notch 602. Further, electronics unit 420 includes a latching recess 710 in an outer surface of electronics unit 420. Latching recess 710 is conventionally fabricated of a dimension corresponding to a portion of the latch stop 600 of a frame panel 400. In one embodiment, electronics unit 420 includes a deflection channel 711 into which the latching recess 710 may be deflected by applying pressure at the point indicated by arrow 730. Panel 400 may be removably engaged to electronics unit 420 by elastically deflecting latching recess 710 into channel 711 of electronics unit 420 by applying force at the location indicated by arrow 730 shown in Fig. 7. As a result of this deflection of latching recess 710, panel 400 may be moved toward electronics unit 420, thereby moving the interior surface of panel 400 adjacent to an exterior surface of electronics unit 420. Upon relaxing the deflection force on latching recess 710, the latch stop 600 of frame 400 moves into position inside of latching recess 710. The result of this action is illustrated in Fig. 8.

As shown in Fig. 8, the frame 400 has been removably engaged to electronics unit 420 by engaging latch stop 600 of frame 400 into latching recess 710 of electronics unit 420. In this manner, frame 400 is securely but removably coupled to electronics unit 420. It will be apparent to one of ordinary skill in the art that equivalent latching structure may be used. For example, an alternative embodiment may exclude the deflection channel in electronics unit 420 but instead fabricate panel 400 from a flexible material, which may be deflected to removably engage latch stop 600 into latching recess 710. In another embodiment, the latch stop traverses the internal perimeter of the frame at arbitrarily broken intervals or patterns, thus enabling the frame and the electronics unit to be uniquely configured to accept coupling with only properly configured patterns of latch stops and cooperating latching recesses.

Also shown in Fig. 8, a transparent plate 410 is captured between frame 400 and electronics unit 420 in transparency recess 602 of frame 400. Transparent plate 410 spanning the aperture 115 of frame 400 provides a means for protecting electronics unit 420 from an exterior environment yet enabling the viewing of a display device of electronics unit 420 through the aperture 115 and transparent plate 410. It will be apparent to one of ordinary skill in the art that transparent plate 410 may be substituted for any conventional transparent medium, such as plexiglass or transparent film. Further, it will be apparent to one of ordinary skill in the art that the frame 400 of the present invention may be used without providing a transparent plate 410 within aperture 115. Again, the beveled edge 640 of frame 400 is illustrated in Fig. 8.

The exterior surface of the frame 400 embodiment illustrated in Fig. 8 is shown as a substantially flat surface except for beveled edge 640. It will be apparent to one of ordinary skill in the art that the exterior surface of frame 400 may be fabricated in a variety of ornamental shapes, configurations, colors, textures, or using other types of conventional fabrication techniques. One such alternative embodiment is illustrated in Figs. 9-14. Fig. 9 illustrates a frontal view of an alternative embodiment of the present invention. The exterior surface of the panel 910 illustrated in Fig. 9 is fabricated with a substantially rounded dimension. This rounded exterior surface can be seen more clearly in the side view of this alternative embodiment illustrated in Fig. 10. Fig. 11 illustrates the interior surface of the alternative embodiment of the present invention. Again, this alternative embodiment includes latch stop 300 and transparency recess 310. Referring to Figs. 12-14, the rounded exterior surface of the alternative embodiment of the present invention is illustrated in more detail. Figs. 12 and 13 illustrate a cross-sectional view of one alternative embodiment of a removable frame 1200 of the present invention. As shown, the exterior surface of frame 1200 is rounded. However, this alternative embodiment of the present invention still includes the latch stop 600 and the transparency recess 602 as shown in Fig. 14. This alternative embodiment is removably coupled to electronics unit 420 in the manner described above.

Thus, a removable frame for coupling to an electronics unit is disclosed. Although the present invention is described herein with reference to a specific preferred embodiment, many modifications and variations therein will readily occur to those with ordinary skill in the art. Accordingly, all such variations and modifications are included within the intended scope of the present invention as defined by the following claims.

The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
