  • Extendable and retractable leg rest
    Patent number: 7540520
    Abstract: An extendable and retractable leg rest includes a first member which is mounted for rotation to a support. A second member supporting a footrest is coupled to the first member and slides relative to the first member as the first and second members rotate, extending away from the first member as the first and second members are rotated into a raised position and retracting toward the first member as the first and second members are rotated into a lowered position. Movement of the second member relative to the first member is driven by a third member coupled to the second member by a gear system.

  • Articulating leg rest for a wheelchair
    Patent number: 7360841
    Abstract: An articulating leg rest is provided having a first member pivotally connected to a base frame. The base frame may be either connected to or part of a wheelchair frame. A second member is telescopically received by the first member. A drive system includes a motor-driven lead screw. First and second housings each have internally threaded portions engaged with the lead screw. A link connects the first housing to the base frame. The second housing engages the second member. Rotation of the lead screw advances the first housing along the lead screw, moving the link and causing the first and second members to rotate relative to the base frame. Rotation of the lead screw also advances the second housing along the lead screw, causing the second housing to linearly translate the second member relative to the first member.
