Abstract
An embodiment of the present invention relates to the protection of electronic displays and includes a guard configured to protect a lighting means while providing an expanded field of view. The guard may include a first element and a second element each having at least a top surface and a wall. The lighting means may be positionable substantially between the first element and the second element such that the top surface of the lighting means is below the first top surface and the second top surface to protect the lighting means from incidental impact. A gap between the first and second elements provides a field of view. The field of view may include a substantially orthogonal line of sight to one side surface of the lighting means.
Claims11
A guard configured to protect a lighting means, the lighting means having a top surface and at least one side surface;
- the guard comprising:
- a first element having a first top surface, a first wall, and a second wall;
- a second element having a second top surface, a third wall, and a fourth wall;
- the first wall and the third wall are angularly disposed at substantially ninety degrees, and the second wall and the fourth wall are angularly disposed at substantially ninety degrees;
- wherein
- the lighting means is disposed between the first element and the second element such that the top surface of the lighting means is below the first top surface and the second top surface;
- the first wall and the third wall define a first gap, the first gap configured to provide a first field of view including at least a first substantially orthogonal line of sight to the at least one side surface of the lighting means;
- and
- the second wall and the fourth wall define a second gap, the second gap configured to provide a second field of view including a second substantially orthogonal line of sight to the at least one side surface of the lighting means.
A housing for an electronic device configured to protect a lighting means, the lighting means having a top surface and at least one side surface, the housing comprising:
- a body portion;
- a guard including:
- a first element having a first top surface and a first wall;
- a second element having a second top surface and a second wall angularly disposed to the first wall by an angle of approximately ninety degrees;
- wherein the lighting means is positionable substantially between the first element and the second element such that the top surface of the lighting means is below the first top surface and the second top surface, and the first element and the second element substantially define at least a first gap, the at least first gap providing a first field of view including at least one first substantially orthogonal line of sight to the at least one side surface of the lighting means;
- wherein the first element further comprises a third wall and the second element further comprises a fourth wall angularly disposed to the third wall, the third wall and the fourth wall substantially defining a at least second gap between the first element and the second element;
- wherein the at least second gap is configured to provide a second field of view including at least one second substantially orthogonal line of sight to the at least one side of the lighting means;
- and
- said first element being out of direct contact with said second element.
