Publication number: 20070046837Abstract: A method for attaching a flat screen display device onto a flat surface using a surface mounted holder is disclosed. The holder includes a plurality of springy electrical contacts and a plurality of hooks each having a latch. The rear surface of the display device includes corresponding electrical contacts for corresponding with the plurality of springy electrical contacts and sockets each with a convex area corresponding to the hooks each having a latch. The method includes mounting the sockets onto the hooks and pushing the display device toward the flat surface by overcoming a biasing force of the springy contacts; and sliding the display device in a direction opposite to the direction of the hooks until the springy electrical contacts engage the corresponding electrical contacts and every convex area is latched by every latch, and is secured by thebiasing force for preventing accidental release of the display device.Type: ApplicationFiled: August 29, 2005Publication date: March 1, 2007Inventor: David Elberbaum

Publication number: 20070046841Abstract: A frame assembly (10) for a television (T) mounted on a wall (W) and extending a distance outwardly from the wall. A generally rectangular shaped frame (12) has a decoratively shaped outer contour. The frame has a rectangular shaped central opening (14) whose length and width correspond to that of the television screen (S). An outer section (12a) of the frame adjacent the central opening is sized to fit over and cover an outer shell (C) of the television. A foot (20) is formed at each corner of the frame to support the frame. A base (22) of each foot rests against the wall. The feet space an inner surface (18) of the frame away from the wall to allow air circulation around a backside of the television and conduct heat produced by the television away from the television and the routing of cables.Type: ApplicationFiled: August 26, 2005Publication date: March 1, 2007Inventors: Donald Jacobsmeyer, Jillian Lopez
