DETAILED DESCRIPTION

[0026] Referring to FIGS. 1-5, one embodiment of a protective display monitor cover 100 is illustrated. The display monitor cover 100 is configured to be mounted over a display monitor 102, as depicted in FIG. 7. For example, the display monitor cover 100 may be configured to be mounted to the front bezel 104 of the display monitor 102, such as by adhesive, glue, fasteners, or other suitable means of mounting the display monitor cover 100 to the display monitor 102. Alternatively, the display monitor cover 100 may be configured to be mounted to a housing, enclosure, bracket, or other structure such that the cover 100 is positioned in front of the display monitor 102. For example, for a seatback mounted display monitor 102, the display monitor cover 100 may be configured to be mounted to a housing, enclosure, or bracket installed in the seatback, such that the display monitor cover 100 covers the display monitor 102 as mounted in the seatback.

[0027] The display monitor cover 100 comprises a main panel 106. The main panel 106 may be formed of any suitable, substantially transparent or translucent material which allows the display monitor 102 to be viewed through the main panel 106. As some examples, the main panel may be made of glass, coated glass, colored glass, or the like. The main panel 106 is sized and shaped to cover an active display area 109 of the display monitor 102. The main panel 106 has an interior surface 108 which faces the display monitor 102 and an exterior surface 110 facing away from the display monitor 102, when the cover 102 is mounted over the display monitor 102 (see FIG. 7). The main panel 106 may have a thickness 122 (see FIG. 4) in the range of 1.0-1.5 mm, for glass. If the main panel 106 is formed of alternative materials, such as polycarbonate or other plastic material, the main panel may be thick such that it has a stiffness and/or strength similar to the glass main panel 106, e.g., in the range of 1.5-2.5 mm.

[0028] The display monitor cover 102 has a rim (or frame) 112 surrounding the perimeter of the main panel 106. The rim 112 may surround, and be attached to, the entire perimeter of the main panel 106, or any portion of the main panel 106 sufficient to securely attach the rim 112 to the main panel 106. The rim 112 may be formed of any suitable material, such as plastic, metal, or the like. The rim 112 has a front surface 114 facing away from the display monitor 102 when the cover 100 is mounted over the display monitor 102, and a rear surface 116 facing towards the display monitor 102 when the cover 100 is mounted over the display monitor 102.

[0029] The front surface 114 of the rim 112 interfaces with the exterior surface 110 of the perimeter of the main panel 106 at a rim interface 118. The rim interface 118 between the front surface 114 of the rim 112 and the exterior surface 110 of the main panel 106 is flush such that the front surface 114 of the rim 112 is flush with exterior surface 110 of the main panel 106. As used herein, the term flush means that adjacent surfaces are even or level and in direct contact with each other.

[0030] As shown in FIGS. 4 and 5, the rim 112 may have a T-shaped cross-section. A first part 121 of the arm of the T-shaped cross-section of the rim 112 has a lateral width 120 extending outward from the rim interface 118. A second part 122 of the arm of the T-shaped cross-section of the rim 112 forms a recessed ledge 122 extending inward from the rim interface 118. The outer edge of the interior surface 108 of the main panel 106 rests on, and may be attached to, the recessed ledge 122. The recessed ledge 122 is recessed from the front surface 114 of the rim 112 and the thickness 124 of the main panel 106, so that the exterior surface 110 of the main panel 106 is flush with the front surface 114 of the rim 112. The bar 126 of the T-shaped cross-section extends rearwardly from the arm. The bar 126 provides structure to the rim 112 for embedding a reinforcing rod 128 into the rim 112. The reinforcing rod 128 extends along the entire rim 112. The reinforcing rod 128 may be a single, integral rod, or multiple rods attached to each other. Alternatively, the reinforcing rod 128 may be formed of multiple rods which extend along respective portions of the rim 112. The reinforcing rod 128 may have a circular cross-section, a square cross-section, a rectangular cross-section, an I-beam cross-section, or other suitable cross-section. The reinforcing rod 128 may be formed of metal, such as steel or aluminum, to increase the stiffness and strength of the rim 112.

[0031] As shown in FIGS. 4 and 5, the main panel 106 has a beveled edge 130 extending along the entire perimeter of the exterior surface 110 of the main panel 106. The rim 112 extends onto the beveled edge 130 thereby mechanically retaining the main panel 106 on the rim 112, and vice versa. In other words, the main panel 106 is mechanically retained on the rim 112 between the rim 112 extending onto the beveled edge 130 and the recessed ledge 122.

[0032] Referring to FIGS. 1, 3 and 5, the display monitor cover 100 has a film 132 applied to the exterior surface 110 of the main panel 106 and the front surface 114 of the rim 112. In other words, the film 132 extends from the exterior surface 110 of the main panel 106 onto the front surface 114 of the rim 112. The film 132 is applied to the entire exterior surface 110 of the main panel 106. The film 132 is adhered to both the exterior surface 110 of the main panel 106 and the front surface 114 of the rim 112. The film 132 may be a substantially transparent or translucent polymeric film, such as polyethylene terephthalate (PET) film, or other suitable film. The film 132 may have a thickness in the range of 0.005 inches to 0.01 inches. The film 132 is adhered to the exterior surface 110 of the main panel 106 and the front surface 114 of the rim 112 using a pressure sensitive adhesive.

[0033] The film 132 extends a sufficient width onto the front surface 114 of the rim 112 such that the film 132 remains adhered to the rim 112 upon an impact to the main panel 106 which breaks the main panel 106, as depicted in FIG. 6. For instance, the film 132 may extend onto the front surface 114 of the rim 112 by at least 0.25 inches, or at least 0.5 inches, or in a range of from 0.25 inches to 0.715 inches, or in a range of from 0.1 inches to 0.75 inches. Hence, upon an impact to the main panel 106 which breaks the main panel 106, the film 132 contains the broken pieces of the main panel 106 from escaping past the film 132.

[0034] As depicted in FIG. 7, when mounted over the display monitor 102, the display monitor cover 100 creates an enclosed space over the display monitor 102 which contains any broken pieces (e.g., broken glass) from both the main panel 106 and the glass screen 103 of the display monitor 102 and prevents the broken pieces from exiting out of the enclosed space.

[0035] Referring now to FIG. 8, a flow chart of one embodiment of a method 200 of manufacturing the display monitor cover 100 for safeguarding a display monitor (e.g., a display monitor having a glass screen) is shown. The method 200 is an insert-injection molding process in which the rim 112 of the cover 100 is injection molded onto a main panel 106 and a reinforcing rod 128. At step 202, the main panel 106 is inserted into an injection mold tool. At step 204, the reinforcing rod 128 is inserted into the injection mold tool. At step 206, plastic material is injected into the injection mold tool such that the rim 112 is injection molded onto the main panel 106 and the reinforcing rod 128. The injection molded rim 112 surrounds the perimeter of the main panel 106 with the rim interface 118 between the exterior surface 110 of the main panel 106 and the front surface 114 of the rim 112 flush. In addition, the injection molding forms the bar 126 of the rim 112 which embeds the reinforcing rod 128 in the bar 126 of the rim 112. The injection molding of the rim 112 onto the main panel 106 may also form a chemical bond between the recessed ledge 122 of the rim 112 and the main panel 106, as well as the rim 112 extending over the beveled edge 130 of the main panel 106 which provides mechanical retention of the main panel 106 to the rim 112.

[0036] At step 208, a film 132 is applied to the exterior surface 110 of the main panel 106 and the front surface 114 of the rim 112. The film 132 is adhered to the exterior surface 110 of the glass panel 106 and the front surface 114 of the rim 112 using a pressure sensitive adhesive. The film 132 extends sufficiently onto the front surface 114 of the rim 112 such that the film 132 remains adhered to the rim 112 upon an impact to the main panel 106 which breaks the main panel 106 into broken pieces.
