Window shelf

Abstract

A window shelf with a first hollow long rectangular box member and a second hollow long rectangular box member having one open end. The open end of the second box member slides over the first box member. A ratchet rail is located within the first box member and engages a pawl mechanism located within the second box member. A rubber end cap located at the end of the first box member and a pair of threaded rubber end caps at the end of the second box member are all situated so that when the first box member is slid outward from the second box member the pawl engages the ratchet rail and prevents the first box member from sliding inward and the threaded extension caps are turned until the window shelf is frictionally engaged with the inside frame walls of a window.

1 . window shelf comprising:
 a first hollow long rectangular box member;   a second hollow long rectangular box member having one open end;   the open end of said second box member capable of sliding over and engaging said first box member;   a ratchet rail located within and parallel to the long direction of said first box member;   a pawl mechanism located within said second box member;   a pawl sliding mechanism capable of releasing said pawl from said ratchet rail;   a rubber end cap located at the end of said first box member;   a pair of threaded apertures located at the end of said second box member   a pair of threaded, rubber tipped extension caps engaged with said threaded apertures at the end of said second box member;   all said elements situated so that when said first box member is slid outward from said second box member by a user, said pawl engages said ratchet rail and prevents said first box member from sliding inward except when said user releases said pawl by engaging said pawl sliding mechanism; and   and said window shelf is affixed to the inside window frame when said rubber end cap of said first box member and said rubber tipped extension caps of said second box member are frictionally engaged with the said inside window frame.
