Illuminated sign device with replaceable lens
A sign device is disclosed. The device includes a mounting frame for mounting a light box to a surface of a vehicle; a lens frame for coupling to the mounting frame and movable between an open position and closed position; and a removable lens retainable by the lens frame such that, when the light box is activated with the lens frame in the closed position, the light box back lights the lens. In the closed position, a seal seals a space between the lens and the light box.
1 . A sign device, the device comprising:
a mounting frame for mounting a light box to a surface;
a lens frame for coupling to the mounting frame and movable between an open position and closed position; and
a removable lens retainable by the lens frame such that, when the light box is activated with the lens frame in the closed position, the light box back lights the lens, wherein, in the closed position, a weathertight seal seals a space between the lens and the light box.
2 . The device of claim 1 , wherein the lens frame comprises one or more retention portions for retaining the lens.
3 . The device of claim 2 , wherein the one or more retention portions are configured to provide one or more gaps between a rear and a front of the lens frame, the gaps being sized complementary to a thickness of the lens.
4 . The device of claim 3 , wherein the lens is removably received in the one or more gaps.
5 . The device of claim 1 , wherein the lens frame is coupled to the mounting frame by a hinge and pivots between the closed and open positions.
6 . The device of claim 1 , wherein the seal is positioned on the mounting frame.
7 . The device of claim 6 , wherein the seal is positioned on a portion of the mounting frame extending into the space between the lens and the light box.
8 . The device of claim 1 , wherein the seal contacts the light box when the light box is mounted to the surface and contacts the lens in the closed position.
9 . The device of claim 1 , wherein the seal extends around the space between the lens and the light box.
10 . The device of claim 1 , wherein the lens frame is capable of being secured to the mounting frame in the closed position such that the seal is subject to compression.
11 . The device of claim 1 , further comprising a latch mechanism to secure the lens frame to the mounting frame in the closed position.
12 . The device of claim 11 , wherein the latch mechanism comprises one or more spring-loaded latches.
13 . A method for replacing a lens of a sign device, the lens being retained by a lens frame, the lens frame being couplable to a light box and/or a mounting frame of the light box, the method comprising:
opening the sign device;
removing the lens;
replacing the lens with a different lens; and
closing the device, thereby engaging a weathertight seal to seal a space between the different lens and the light box.
14 . The method of claim 13 , wherein opening the sign device comprises moving the lens and/or the lens frame from a closed position to an open position.
15 . The method of claim 13 , wherein opening the sign device comprises releasing a latch mechanism that secures the lens to the light box and/or to the mounting frame.
16 . The method of claim 13 , wherein opening the sign device comprises pivoting the lens and/or the lens frame away from the light box.
17 . The method of claim 13 , wherein removing the lens comprises removing the lens from one or more retention portions of the lens frame.
18 . The method of claim 13 , wherein engaging the seal comprises applying compression to the seal.
19 . The method of claim 13 , wherein engaging the seal comprises securing the lens and/or the lens frame to the light box and/or to the mounting frame.
20 . A sign device, the device comprising:
a light box for mounting to a surface of a vehicle;
a lens frame for coupling to the light box and movable between an open position and closed position such that, when the light box is activated with the lens frame in the closed position, the light box illuminates a lens, wherein, in the closed position, a weathertight seal seals a space between the lens and the light box.
