Emergency light system housing with two replaceable covers
View Patent ↗Emergency light system housing, with two replaceable covers is invented to supplement the prior art, U.S. Pat. No. 6,741,324 B1. The disadvantage of prior art is that it does not permit the cover of emergency light system housing to be replaceable. However, the present invention resolved this disadvantage by the way that it, creatively positions three connecting members on the cover and positions three holes on the housing. Three connecting members on the emergency light cover come to be respectively combined into three holes on the emergency light system housing. The shape of emergency light cover could be various as far as three connecting members on the emergency light cover are Properly positioned as described in the claim so that they come to be respectively combined into three holes on the emergency light system housing. The present invention could reduce an economic burden on an user because he or she could change only a different shape of emergency light cover with an existing cover without a need to change an entire emergency light system including housing with a circuit board and two covers with new one. In addition, the present invention is designed to shed a light in any direction by attaching the replaceable cover and the movable ball-shaped emergency light with a movable plastic circle. However, the movable emergency light is designed neither to be turned left or right side beyond 360 degree because of both one protruded-up and square-shaped object attached to the plastic moving circle and one blocking object located in the respective replaceable cover, nor to be turned downward or upwards beyond 80 degree because of both two protruded-up cross-shaped lines on each surface of two respective plastic ball-shaped covers and two respective smaller holes located in the movable plastic circle.
1. An emergency light housing comprising:
a first housing including:
a left-side bottom surface and a right-side bottom surface, and
a middle part located between the left-side and the right side bottom surface, protrudes up from planes of the left-side and the right-side bottom surface, has a right-sided wall and a left-sided wall, and contains a circuit board inside;
a left-sided replaceable cover covering both the left-side bottom surface and the left-sided wall and having a first connecting push-in member and
a right-sided replaceable cover covering both the right-side bottom surface and the right-sided wall and having a second connecting push-in member,
wherein a first hole and a second hole are respectively located in the left-sided and the right-sided wall, and the first and the second connecting push-in member are respectively pushed into the first and the second hole,
wherein a left-sided emergency light is located on the left-sided replaceable cover, and a right-sided emergency light is located on the right-sided replaceable cover, and
wherein a third hole and a fourth hole are respectively located in the left-sided and the right-sided wall, electric lines are connected between the left-sided emergency light and the circuit board through the third hole, and other electric lines are connected between the right-sided emergency light and the circuit board.
2. The emergency light housing of claim 1 , wherein the circuit board is placed in empty space inside of the middle part between the left-side and the right-side bottom surface.
3. The emergency light housing of claim 1 , wherein the right-sided and the left-sided wall are slightly inclined.
4. The emergency light housing of claim 1 , wherein the left-sided wall has another long rectangular hole so that air could freely circulate between the first housing and the left-sided replaceable cover while the first housing and the left-sided replaceable cover are attached to each other.
5. The emergency light housing of claim 1 , wherein each of the third and fourth hole has long rectangular shape, wherein the third hole is located in a bottom middle of the left-sided wall, and the fourth hole is located in a bottom middle of the right-sided wall.
6. The emergency light housing of claim 1 , wherein the left-side bottom surface has a rounded hole so that a rounded cover of the left-sided emergency light shall be placed into the rounded hole,
wherein the left-side bottom surface has two small rectangular holes, one of the two small rectangular holes is located in an upper left corner of the left-side bottom surface, and the other of the two small rectangular holes is located in an upper right corner of the left-side bottom surface, and
wherein two small connecting push-in members attached to the left-sided replaceable cover are respectively pushed into the two small rectangular holes.
7. The emergency light housing of claim 1 , wherein the right-side bottom surface has a rounded hole so that a rounded cover of the right-sided emergency light shall be placed into the rounded hole,
wherein the right-side bottom surface has two small rectangular holes, one of the two small rectangular holes is located in an upper left corner of the right-side bottom surface and the other of the two small rectangular holes is located in an upper right corner of the right-side bottom surface, and
wherein two small connecting push-in members attached to the right-sided replaceable cover are respectively pushed into the two small rectangular holes.
8. The emergency light housing of claim 1 , wherein the first housing has a bottom cover so that a circuit board shall be blocked not to be seen from outside.
9. The emergency light housing of claim 1 , each of the left-sided and the right-sided emergency light comprises a plastic ball-shaped covers containing an actual light in it and a transparent covers located on a top of the plastic ball-shaped lights.
10. The emergency light housing of claim 9 , wherein the plastic ball-shaped cover has a bottom holes on a south poles of the plastic ball-shaped covers, and electricity lines are connected to the circuit board through the bottom hole,
wherein the plastic ball-shaped cover has two protruded-up lines on the surface of the plastic ball-shaped cover, one of the two protruded-up lines extends from an end of the transparent cover to one centimeter before the bottom hole and the other of the two protruded-up lines extends from the opposite end of the transparent cover to one centimeter before the bottom hole, and
wherein each of ends of two protruded-up lines located in one centimeter before the bottom holes has a protruded-up cross-shaped lines so that the protruded-up cross-shaped line prevents the left-sided and the right-sided emergency lights from becoming upside-down.
11. The emergency light housing of claim 1 , wherein the left-sided replaceable cover has a plastic circle connecting between the left-sided replaceable covers and the left-sided-emergency lights, and the right-sided replaceable cover has a plastic circle connecting between the right-sided replaceable cover and the right-sided emergency light.
12. The emergency light housing of claim 11 , the plastic circle has a protruded-up and square-shaped object.
13. The emergency light housing of claim 11 , wherein each of the left-sided and the right-sided replaceable cover has a blocking object inside of each of them to prevent each of the left-sided and the right-sided emergency light from turning left or right side beyond more than 360 degree.
