  "abstract": "There is disclosed a storm shutter installation for a building window wherein channels are affixed to the building adjacent the upper and lower parts of the window. A panel is inserted into the channels by placing the upper edge thereof in the upper channel, elevating the panel until the lower panel edge clears the lower channel, swinging the lower panel edge into alignment with the lower channel and lowering the panel into the lower channel. The lower channel is constructed so that the opening thereof may be positioned on either a horizontal sill or on a slanted sill and aligned with the upper channel. Means are provided for tightly grasping the panel in the lower channel.",
  "claims": [
    "1. A storm shutter installation comprising an enclosure window including a sill adjacent the lower part thereof; a stationary downwardly opening upper channel adjacent the upper part of the window; and a stationary upwardly opening lower channel resting on the sill and cooperating with the upper channel for supporting and captivating a panel; the lower channel including means integral therewith for orienting the channel opening generally vertically if the sill is either horizontal or inclined downwardly away from the window, the orienting means comprising a member extending from the bottom of the lower channel away from the upper channel, the bottom of the member providing a support for abutting a downwardly inclined sill for maintaining the lower channel opening generally vertical, the member and the bottom of the lower channel defining a generally triangular section free of obstructions for receiving therein the corner of a generally horizontal sill.",
    "2. The installation of claim 1 wherein the lower channel is of generally U-shaped cross section having vertical legs projecting toward the downwardly opening channel and a horizontal wall spanning the legs, the member projecting away from the upper channel in a direction generally opposite to the leg further from the window.",
    "3. The installation of claim 1 wherein the lower channel includes a first upstanding leg near the window; a second upstanding leg further from the window; the second upstanding leg extending below a generally horizontal plane through the lower end of the first leg; and the lower end of the first leg, the plane and the second leg below the plane defining a generally triangular section free of obstructions.",
    "4. The storm shutter of claim 1 wherein the sill is horizontal and provides a corner, the corner being received in the triangular section.",
    "5. The storm shutter of claim 1 wherein the sill is downwardly inclined from the window, the bottom of the member being supported on the sill and maintaining the opening generally vertical."
