In a keyboard support arm assembly including a base frame for attachment to the underside of a support surface, said base frame including a front, a back and opposite sides, said keyboard support arm assembly further including first and second parallel spaced slide tracks in the base frame extending between the front and back of the base frame, each track including a keyboard arm support and slide mechanism, said keyboard support arm assembly further including a keyboard plate for assembly with the base frame slide mechanism of said first and second slide tracks whereby a keyboard arm may be mounted on said keyboard plate and supported for sliding movement between the front and back of the base frame, the improvement comprising, in combination:an adapter bracket for attaching the keyboard plate to the slide mechanisms, said bracket including a housing having at least one projecting support hook, at least one of said slide mechanisms including at least one hook receptor, said housing further including at least one attachment flange; a fastener for attaching the housing attachment flange to at least one of said slide mechanisms, whereby the hook and fastener together support said housing on the said slide mechanisms, and a keyboard plate support and retention channel in the housing for receipt of the keyboard plate.
- 2. The support arm assembly of claim 1 wherein the housing has a front end and a back end and said hook comprises a first projecting support hook and a second projecting support hook at one end of the housing, and said housing attachment flange comprises a first slotted attachment flange at the other end of said housing and a second slotted attachment flange at the other end of said housing, said first and second slide mechanisms each including a hook receptor and a fastener opening whereby each slide mechanism is engageable by one hook and may be fastened to one slotted flange.
- 3. The support arm assembly of claim 1 wherein the housing includes opposed, spaced, keyboard plate engaging slots to receive and support the keyboard plate.
- 4. The support arm of claim 3 wherein the keyboard plate is at least partially circular and rotatably mounted in the plate engaging slots.
- 5. An adapter for attaching a keyboard arm having a connection plate for attachment to a base frame, said base frame having a front and a back, said base frame being attachable to the underside of a support surface and including first and second, spaced parallel slide members movable between the front and back of the base frame, said adapter comprising, in combination:a housing, said housing having a front end, a back end and spaced sides between the ends, a projecting hook at one end of the housing and a projecting flange at the other end of the housing, said hook adapted to fit over one of said slide members to support the adapter and the flange configured for attachment to one of said slide members by a fastener, and said housing including connection plate receiving slots in the adapter for receiving the keyboard arm connection plate whereby the connection plate is retained in the adapter and the adapter is connectable to the said slide members by engaging said hook with one of said slide members and attaching said flange to one of said slide members with said fastener.
- 6. The adapter of claim 5 further including a separate glide member comprising the plate receiving slot of the adapter housing.
- 7. The adapter of claim 6 wherein the connection plate is at least partially round and the glide member includes an arcuate slot for rotatably receiving the connection plate.
- 8. The adapter of claim 6 wherein the housing is formed from metal and the glide member is a polymeric material.
