Claims
- 1. A magnetic letter board assembly comprising the combination of a substantially rigid magnetic letter board composed of one material and a plurality of removably magnetically secured magnetic graphic indicia bodies each composed of a material different from and appreciably more flexible than said letter board and arranged on said board to display a message, wherein the front surface of said board and the rear surface of each of said graphic indicia bodies each have a pair of cooperating inwardly converging walls and a surface bridging said walls, each defining lands and grooves and a recess between them extending in the same direction, and each of said graphic indicia bodies has a flexibility permitting the selective lifting of said graphic indicia body from said board and its manipulating along said walls and surface for remounting on said board.
- 2. In the magnetic letter board assembly recited in claim 1, wherein said letter board is metal made from magnetizable material.
- 3. In the magnetic board assembly recited in claim 1, wherein each said graphic indicia bodies comprises a formed body of rubber-like material having magnetizable material embedded therein.
- 4. In the magnetic board assembly recited in claim 3, wherein each said graphic indicia body has one or more graphic indicia arranged on its front surface opposed to said rear surface carrying said walls and bridging wall.
- 5. In the magnetic board assembly recited in claim 4, wherein said front surface of said graphic indicia body is of lesser cross section than said rear surface and said rear surface defines a background for said front surface.
- 6. In the magnetic board assembly recited in claim 5, wherein said front surface is of a contrasting finish to said rear background surface.
- 7. In the magnetic letter board assembly recited in claim 4, wherein said body and graphic indicia are integrally formed.
- 8. In the magnetic board assembly recited in claim 1, wherein said graphic indicia body has a tapered wall parallel to one of said inwardly converging walls and a wall extending from said tapered wall aligned with said bridge wall.
- 9. In the magnetic board assembly recited in claim 8, wherein said tapered wall and said wall extending therefrom are arranged on an edge of said graphic indicia body.
- 10. A magnetic letter board assembly comprising the combination of a substantially rigid letter board composed of one material and a plurality of removably magnetically secured magnetic graphic indicia bodies arranged on said board to display a message, wherein (a) the combined area of said bodies does not exceed the area of said board, (b) at least the front surface of said board or the rear surface of each of said graphic indicia bodies has a magnetic field and the other surface is attracted to said magnetic field, and (c) the front surface of said board and the rear surface of each of said graphic indicia bodies include means for orienting said bodies relative to said board and to each other, said means including, on the front surface of said board and the rear surface of each of said graphic indicia bodies a pair of cooperating inwardly converging walls and a surface bridging said walls, each defining lands and grooves and a recess between them extending in the same direction, and each of said graphic indicia bodies are adapted for selective lifting of said graphic indicia body from said board and manipulated along said walls and surface for remounting on said board.
- 11. In the assembly recited in claim 10 wherein said pair of cooperating inwardly converging walls and said surface bridging said walls of said front surface of said board comprise a first set of surfaces of said front surface and said first set has a generally horizontal orientation and further including a second set of surfaces of said front surface comprising a pair of cooperating inwardly converging walls and a surface bridging said walls and having a generally horizontal orientation generally parallel to said first set.
- 12. In the magnetic letter board assembly recited in claim 11, wherein said board has a greater number of pairs of walls than each said graphic indicia body.
- 13. In the magnetic letter board assembly recited in claim 11, wherein each said graphic indicia body has on at least one of its edges parallel to said recess a wall parallel to one of said recess walls and a flat bottom wall co-planar with said recess wall.
- 14. In the assembly recited in claim 11 wherein said bodies are composed of a material different than said letter board.
- 15. In the magnetic letter board assembly recited in claim 14, wherein said graphic indicia body is rubber-like and flexible.
- 16. In the magnetic letter board assembly recited in claim 14, wherein said letter board is stamped from magnetizable metal material and flat except for said walls.
- 17. In the magnetic letter board assembly recited in claim 14, wherein a plurality of sets of said walls are provided parallel to one another in a horizontal direction and equal distantly spaced apart on said board to define the horizontal alignment of a plurality of indicia bodies on said board, and a plurality of vertically arranged indicia bodies may be slid along said walls to vertically align said indicia bodies relative to one another.
- 18. In the assembly recited in claim 11 wherein each of said sets has a sufficient length to permit a plurality of said bodies to be mounted thereon side by side.
- 19. In the magnetic board assembly recited in claim 18, wherein said graphic indicia body is larger than the space between said plurality of space apart ridges.
- 20. In the assembly recited in claim 18 wherein said front surface of said board has a sufficient number of sets of said surfaces to accommodate the mounting of at least two of said bodies on said front surface where said bodies of said plurality have a generally vertical orientation relative to each other.
