Abstract
A slat for use in a rolling shutter is provided. The slat comprises a hooking track located at a first edge of a body and a receiving track located at a second edge of the body. Illustratively, the hooking track has a hook-shaped profile, and the receiving track comprises a lip member and a guard member defining a space adapted to receive therein an engaging track of an adjacent slat. The hooking track and the receiving track are designed to minimize the space required for the rolling shutter to be retracted around a spindle.
Claims18
A slat for a rolling shutter, comprising:
- a single-walled body having a curvature with a radius of curvature, a convex outward facing side and a concave inward facing side, a first end and a second end;
- a hooking track positioned at the first end;
- a bend formed between the body and the hooking track, wherein the hooking track projects outward above the convex side of the body and does not extend inward below the concave side of the body;
- a receiving track positioned at the second end, the receiving track including a guard member extending along the curvature of the body, and a lip member projecting inward below the concave side of the body;
- and
- an articulation space defined between the lip member and guard member, the articulation space sized and shaped to hingedly engage the hooking track.

A rolling shutter, comprising:
- a spindle;
- a plurality of slats, each slat comprising:
- a single-walled body having a curvature with a radius of curvature, a convex outward facing side and a concave inward facing side, a first end and a second end;
- a hooking track positioned at the first end;
- a bend formed between the body and the hooking track;
- a receiving track positioned at the second end, the receiving track including a guard member that extends along the curvature of the body, and a lip member projecting inward below the concave side of the body;
- and
- an articulation space defined between the lip member and guard member, the articulation space sized and shaped to hingedly engage the hooking track;
- wherein the plurality of slats form a chain extending from the spindle, the hooking track of each successive slat engaged in the receiving track of the preceding slat in the chain;
- and
- wherein the rolling shutter has a retracted position with the plurality of slats wound about the spindle in a first winding and a second successive winding, and the hooking track of each slat in the first winding is overlapped by the body of a slat in the second successive winding and is adjacent to the receiving track of the slat in the second successive winding.

A rolling shutter, comprising:
- first and second slats, each slat comprising:
- a single-walled body having a curvature with a radius of curvature, a convex outward facing side and a concave inward facing side, a first end and a second end, the convex side having a first surface with a first surface curvature;
- a hooking track positioned at the first end, the hooking track having an outer second surface;
- a bend formed between the body and the hooking track, wherein the hooking track projects outward above the convex side of the body and does not extend inward below the concave side of the body;
- a receiving track positioned at the second end, the receiving track including a guard member extending along the curvature of the body and a lip member projecting inward below the concave side of the body, the guard member having an outer third surface;
- and
- an articulation space defined between the lip member and guard member, the articulation space sized and shaped to hingedly engage the hooking track;
- wherein the hooking track of the first slat is engaged in the receiving track of the second slat, and the first and second slats having a vertical position wherein the second surface of the first slat does not project beyond a tangent to the third surface of the second slat.
