Abstract
A portable information handling system keyboard having infinity keys with a beveled bottom surface perimeter is provided enhanced rigidity with a hidden lattice have support lines of raised material, such as stainless steel, aligned below the beveled bottom surface perimeter of the keys. The lattice provides structural support while remaining substantially hidden from the upper key surface of an infinity keyboard.
Claims20
An information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions that process information;
- a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- and
- a keyboard coupled to the housing, the keyboard having plural keys, each key biased to an elevated plane by a biasing device and operable to accept an end user press to an input plane, at least some of the plural keys having an upper surface with adjacent perimeters and a lower surface with beveled perimeters, a lattice disposed within the beveled perimeters and hidden below the plural keys by the adjacent perimeters, a downward press on the keys provided vertical room relative to the lattice by the beveled perimeters.
2 more elements
A method for assembly of a keyboard, the method comprising:
- forming plural keys having a beveled perimeter at a lower surface;
- coupling a lattice to a support plate, the lattice aligning with the beveled perimeters;
- and
- coupling the plural keys to the support plate biased to an elevated plane, each key configured to accept a press to an input plane, the beveled perimeters disposed over the lattice to align upper surface perimeters of the plural keys adjacent to each other thereby hiding the lattice from view above the plural keys.
1 more element
A keyboard comprising:
- a support plate;
- a membrane disposed over the support plate and operable to detect key presses as touches pressed against the support plate;
- plural keys disposed over the membrane in an elevated plane, each key operable to press down to an input plane to touch the membrane to indicate an input, each key having a bevel feature on at least one side of the perimeter of the key bottom surface;
- and
- a lattice having plural openings defined by lines of material raised relative to the support plate, each opening aligned with one or more of the plural keys, the lines each aligned between adjacent keys and under the bevel feature of both of the adjacent keys, the lattice lines disposed under the bevel feature are substantially hidden when viewed from a top surface of the plural keys, a front row of the plural keys have an extended front face at the bottom surface and the bevel feature around the remainder of the bottom surface perimeter and the lattice terminates without extending under the front face.
