SPEAKER SHELF
Field of the Invention
The present invention relates to supporting devices above a video display in general and in particular to a device for supporting a speaker above a flat panel television.
Background of the Invention
It is well know that modern home theater systems typically include a video display such as a television, an input source such as a DVD or VHS player, a processing device such as an audio visual receiver, and a plurality of speakers. One of the plurality of speakers typically includes a center channel speaker. The center channel speaker is known to be important for locating dialogue and other sounds associated with a corresponding image displayed on the television.
In designing and setting up home theater systems, it is known that the position and orientation of the center channel speaker is important for ensuring accurate reproduction of the required audio signals. It is known that the center channel speaker is desirably located vertically centered in relation to the screen and either below or above the screen. It is also often desirable to locate the front of the speaker co-planar with the screen. Accordingly, it has previously been common to place the center channel speaker resting on the top of the television cabinet.
Due to advances in television technology, flat panel televisions such as plasma or Liquid Crystal Display (LCD) panel televisions have become more prevalent in home theater systems. Flat panel televisions disadvantageously have a reduced depth on top of the television cabinet on which to rest a speaker. The depth of such flat panel televisions is typically less than 4 inches.
Conversely, many center channel speakers have cabinet depths which are substantially greater than 4 inches. Accordingly, it is often not possible to place a center channel speaker
directly upon a flat panel television.

Detailed Description of Embodiments of the Invention
Referring to Figure 1, an apparatus for supporting a speaker 9 above a television 4 according to a first embodiment of the invention is shown generally at 10. The television 4 has front and rear surfaces 6 and 8, respectively and a top surface 7 extending therebetween. The junction of the front and top surfaces defines a front top edge 6a. The junction of the rear surfaces defines a rear top edge 8 a.
Turning to Figures 2 and 3, a perspective view of the speaker shelf 10 is illustrated. The apparatus or speaker shelf 10 comprises a top platform 12, a front lip 14 and a rear grip 16. The top platform comprises a planar member having front and back ends 18 and 20, respectively and extending between first and second side edges 22 and 24, respectively. The first and second side edges 22 and 24 maybe parallel to or angled with respect to each other. It will be appreciated that other shapes of the top platform 12 may be useful as well. The front lip 14 extends substantially perpendicularly from and in a downward direction relative to the front end 18. As illustrated in Figures 1 through 5, the front lip 14 and top platform 12 maybe formed of a continuous sheet of material having a 90 degree bend 26 therein wherein the bend 26 defines the boundary between the top platform 12 and the front lip 14. The front lip 14 may comprise a single lip as illustrated in Figure 2 or more than one lip 14a and 14b as illustrated in Figure 1. The bend 26 may also be selected from a range of between 80 and 120 degrees. It will be appreciated that the front lip 14 should have a length sufficient to engage a portion of the front surface 6 of the television 4. It is also desirable that the front lip 14 not extend over and obstruct the screen (not shown) of the television 4. It has been found a length of between Vz and 1 Vi inch for the front lip has been useful although it will be appreciated that other lengths may be useful for different television designs as well.
As illustrated, the speaker shelf 10 may optionally include a sheet of cushioning material 32 applied to the bottom 28 of the top platform 12 and the rear surface 30 of the front lip 14. The cushioning material 32 may comprise an elastomeric material such as, for example, rubber, butyl
rubber or polychloropene which is often sold under the trade name Neoprene™.
The rear grip 16 comprises an elongate threaded rod 34 threadably received -within a bracket 36. The threaded rod 34 includes an end pad 42 for resiliently engaging the rear surface 8 of the flat panel television 4. The end pad 42 may be rotatably affixed to the threaded rod 34. The bracket 36 is an elongate member extending substantially perpendicularly from the bottom 28 of the top platform 12. The bracket 36 maybe secured to the top platform 12 by means of screws 38 or other suitable fastening methods as are commonly known in the art. The bracket 36 includes a threaded bore 40 adapted to threadably receive the rod 34 therein. Each bracket 36 may include a plurality of bores 40 for receiving the threaded rod 34 at a plurality of locations. The bore 40 is spaced apart from the top platform 12 by a distance sufficient to permit the end pad 42 to engage the rear surface 8 of the flat panel television 4 so as to avoid any edge bevel of the rear surface. It has been found that spacing the bore 40 from the top platform by a distance of approximately 3 to 8 inches has been sufficient. The rod 34 may also include a nut 44 for locking the rod at a selected location relative to the bracket 36. It will be appreciated that a nut 44 may also be applied to both sides of the bracket as illustrated in Figures 3 through 5.
As illustrated in Figure 1 , the rear grip may include a plurality of brackets 36 each having a threaded rod 34. The two brackets maybe spaced apart in a common plane to each other such that each bracket 36 is located adjacent to one of the first or second side edges 22 or 24 of the top platform 12. It will also be appreciated that a single bracket 36 may be utilized wherein the threaded rod 34 is centred between the first and second side edges 22 and 24. In other embodiments a single bracket 36 may substantially span the width between the first and second side edges 22 and 24 and may include a plurality of threaded rods 34, as illustrated in Figure 2.
The top platform 12, front lip 14 and bracket 36 may be formed of any suitable rigid material. It has been found that aluminium has been useful as well as other types of metal such as steel and stainless steel. It will be appreciated that other materials may also be useful such as, by way of non-limiting example, wood and rigid plastics sufficient to permit the speaker shelf to
