Abstract

There is provided a sign insert that can house the inner components of a sign. The insert can be easily inserted into and removed from signs so that either of the sign housing or the sign insert with inner components can be salvaged and reused if the other becomes inoperable.

Claims

1. A removable insert adapted to fit within an illuminated sign comprising a sign housing and a sign legend to be displayed by the illuminated sign, the insert comprising:

(a) at least one inner wall and at least one outer wall, wherein the at least one outer wall is shaped to be inserted into and generally correspond to a shape of a sign housing and wherein the at least one inner wall is shaped so as not to encroach on a sign legend;

(b) a plurality of cavities defined between the at least one inner wall and the at least one outer wall, wherein the plurality of cavities define discrete compartments adapted to house, store, or mount various sign components; and

(c) at least one structure for supporting a circuit board.

2. The removable insert of claim 1, wherein the at least one inner wall substantially conforms to an exterior of the sign legend.

3. The removable insert of claim 1, further comprising a light source positioned at either a top or a bottom area of the sign insert and a reflector positioned opposite the light source at the other of the top or bottom of the sign insert.

4. The removable insert of claim 3, wherein the reflector comprises two angled side walls oriented relative to each other and forming a cavity.

5. The removable insert of claim 4, where the angled side walls are oriented between about 40 degrees to about 120 degrees relative to each other.

6. The removable insert of claim 3, wherein the reflector comprises an inverted tip.

7. The removable insert of claim 3, wherein the reflector is integrally formed with the insert, removable from the insert, or hingedly attached to the insert, such that it forms an additional cavity for sign components.

8. The removable insert of claim 1, wherein the insert snap fits into the sign housing.

9. The removable insert of claim 1, wherein the insert snap fits into the sign housing via at least one cooperating protrusion and recess system located on portions of the removable insert and the sign housing.

10. The removable insert of claim 1, wherein the at least one structure that supports the circuit board comprises grooves into which the circuit board can slide.

11. The removable insert of claim 1, wherein the compartments are adapted to store, house, or mount one or more of a battery, a voltage conversion device, an additional power supply, a directional indicator assembly, or a speaker.

12. The removable insert of claim 1, further comprising at least one biasing structure adapted to bear against and exert pressure on a canopy of a mounting device in order to bias the mounting device against a mounting surface.

13. The removable insert of claim 12, wherein the at least one biasing structure is a spring.

14. An illuminated sign system comprising a sign housing and the removable insert of claim 1 positioned within the sign housing.

15. The system of claim 14, further comprising a mounting device comprising:

(a) a mounting plate comprising a mounting base having at least one positioning element and at least one lip element formed thereon;

(b) a canopy element adapted to be positioned over the mounting plate, the canopy element comprising (i) at least one positioning element aperture adapted to receive the at least one positioning element;

(ii) at least one lip element aperture adapted to receive the at least one lip element; and

(iii) at least one upstanding stabilizing element extending from an upper surface of the canopy; and

(c) a locking clip adapted to cooperate with at least a portion of the mounting plate and the canopy element.

16. The system of claim 15, wherein the insert has at least one side wall with at least one guide track defined therein, and wherein the locking clip has at least one leg with at least one tab that is adapted to be received in the at least one guide tack.

17. The removable insert of claim 1, comprising at least one mounting aperture adapted to receive one of a mounting device or a plug that covers any unused mounting apertures.

18. The removable insert of claim 17, wherein the plug comprises a base from which at least one leg extends and wherein the at least one leg comprises a protrusion distal the base and adapted to engage a biasing structure on the sign insert.

19. A method of assembling an illuminated sign comprising:

(a) providing a first sign housing;

(b) providing a first removable sign insert according to claim 1; and

(c) positioning the first removable insert in the first sign housing.

20. The method of claim 19, further comprising:

(d) providing a second sign housing;

(e) removing the first removable insert from the first sign housing and positioning the first removable insert in the second sign housing.

21. The method of claim 19, further comprising:

(d) providing a second removable insert;

(e) removing the first removable insert from the first sign housing and positioning the second removable insert into the first sign housing.

22. The method of claim 19, wherein the first removable insert is adapted to be snap fit with respect to the first sign housing.

23. The removable insert of claim 1, wherein the insert comprises a polymeric material and wherein the sign housing comprises a metal housing.
