A tray assembly mounted on a wheelchair. A housing containing the tray is mounted along the side of the chair arm. The tray assembly has a tray surface moveable between a stowed and unstowed position.
1. A stowable support system, comprising:
a housing having a first side, a second side, a front, a back, a bottom, and a pivoting armrest collectively forming a hollow structure when said pivoting armrest is in a closed position;
a single support arm having an elongated body, a first end, and a second end, said first end of said support arm being hingedly connected to said housing, said support arm rotating in a vertical plane about a horizontal hinge axis by essentially 180° from a first position within said housing to a second position outside of said housing, said support arm also being pivotally connected to said housing, wherein said support arm pivots in a horizontal plane about a vertical pivot axis by at least about 180° while in said second position; and
a tray having an outer portion and an inner portion, said inner portion of said tray being hingedly connected to said outer portion of said tray, said outer portion of said tray being slideably connected to said support arm allowing said tray to slide along said elongated body of said support arm, said outer portion of said tray also being hingedly connected to said support arm allowing said tray to pivot between a vertical closed position and a horizontal operational position while said support arm is in said second position outside of said housing.
2. A stowable support system as in claim 1 , further comprising:
support means to hold said inner tray in a tilted position.
3. A stowable support system as in claim 1 , further comprising:
said inner portion of said tray being transparent.
4. A stowable support system as in claim 1 , further comprising:
actuation means to remove said tray from said housing.
5. A stowable support system as in claim 1 , further comprising:
said support arm being hingedly connected to said housing by a friction hinge to reduce amount of effort required to transition said support arm between said stowed position and said unstowed position.
