Abstract

In a window comprising a stationary frame and a movable sash, the sash is tiltable on an axis that during the opening motion of the sash is displaceable away from the frame substantially parallel to the plane thereof.

Claims

1. A window for installation in a roof of a building, comprising:

a rectangular frame, including a pair of lateral frame members, a bottom frame member, and a top frame member;

a sash, including corresponding lateral, top, and bottom sash members;

a pair of slide rails respectively extending displaceably along said lateral frame members and hingedly connected to said sash adjacent the top member thereof; and

a pair of link arms having first ends respectively journaled to said frame at about the respective central regions of said lateral frame members and second ends journaled to said sash adjacent the bottom member thereof, said link arms at said first ends being interconnected through an internal maneuvering handle, said handle including a pair of lateral maneuvering arms connected to said link arms at said first ends, and a grip rod rigidly interconnecting said maneuvering arms and extending substantially perpendicular thereto at a point spaced from said first ends, displacement of said handle causing a corresponding displacement of the sash with respect to the fixed frame, said bottom member of the sash following a path, during the opening or closing motion of the sash, that is defined by the fixed length of the link arms, and said top of the sash moving laterally along a path defined by the slide rails, said slide rails being oriented in a plane parallel to and displaced from the plane defined by said link arms.

2. A window as claimed in claim 1, wherein said link at one end is journalled to said sash by means of a pin-and slot connection.

3. A window as claimed in claim 1, further comprising a sash weight compensator inserted between said sash and said link.

4. A window, primarily for installation in a roof of a building, comprising:

a frame, including a pair of lateral frame members, a bottom frame member, and a top frame member;

a sash, including lateral, top and bottom sash members corresponding to the lateral, top, and bottom frame members of said frame, said frame and said sash being structurally adapted to define a closed window position; and

means movably connecting said sash to said frame and cooperating therewith to cause said sash to be removed from said frame to define an opened window position, said connecting means comprising;

a. a pair of slide rails respectively extending displaceably along said lateral frame members and hingedly connected to said sash near the top member thereof,

b. a pair of link arms including first ends thereof respectively journaled to said frame at about the respective central regions of said lateral frames, and second ends journaled to said sash near the bottom member thereof, and

c. an internal maneuvering handle interconnecting said first ends of said link arms, said handle including a pair of lateral maneuvering arms connected to said link arms at said first ends, and a grip rod rigidly interconnecting said maneuvering arms and extending substantially perpendicular thereto at points spaced from said first ends, displacement of said handle causing a corresponding displacement of the sash with respect to the fixed frame, said bottom member of the sash following a path, during the opening or closing motion of the sash, that is defined by the fixed length of the link arms, and said top of the sash moving laterally along a path defined by the slide rails, said slide rails being oriented in a plane parallel to and displaced from the plane defined by said link arms.
