Abstract

A curtain support assembly is provided. The curtain support assembly includes a first rail, a second rail, and a connector. The first and second rails each include slide surfaces for supporting a curtain carrier moving along a curtain travel path. The connector includes a first end connected to the first rail and a second end connected to the second rail such that the first and second rails are separated from each other by a gap having a predefined distance. The connector further includes a ramp having a length greater than the predefined distance. The connector is configured such that a curtain carrier moving along the curtain travel path from the first rail to the second rail is supported by the ramp.

3 . The curtain support rail connector of claim 1 , wherein an outer edge of the center portion is positioned between a top surface of the connector and a bottom surface of the connector.

4 . The curtain support rail connector of claim 1 , wherein the center portion has a length less than the predefined distance of the gap.

5 . The curtain support rail connector of claim 1 , wherein the connector is curved and defines an angle measured between the first end of the connector and the second end of the connector, and wherein the angle is at least 80 degrees.

6 . The curtain support rail connector of claim 5 , wherein the angle is less than 180 degrees.

7 . A curtain support rail connector for connecting curtain support rails, the connector comprising:

a body having a first end, a second end opposite the first end, and a first side surface extending between the first end and the second end;

a first flange extending away from the first end of the body and configured to connect to a first curtain support rail;

a second flange extending away from the second end of the body and configured to connect to a second curtain support rail such that the first curtain support rail and second support rail are separated by a gap having a predefined distance defined by the body when connected to the first end and second end of the body;

a ramp having a length greater than the predefined distance; and

a gap surface extending between an inner surface of the ramp and the first side surface of the body such that the gap surface, the inner surface of the ramp, and the first side surface define a groove;

wherein a curtain carrier travels along the groove and is supported by the ramp when the curtain carrier moves between the first curtain support rail and the second curtain support rail.

8 . The curtain support rail connector of claim 7 , wherein a length of the groove is equal to the predefined distance of the gap.

9 . The curtain support rail connector of claim 7 , wherein the length of the ramp is greater than a length of the groove.

10 . The curtain support rail connector of claim 7 , wherein the gap surface extends along a plane perpendicular to the first side surface of the body.

11 . The curtain support rail connector of claim 7 , wherein the ramp includes a first angled portion for locating adjacent to the first curtain support rail, a center portion for locating adjacent to the gap, and a second angled portion for locating adjacent to the second support rail.

12 . A curtain support assembly, comprising:

a first rail including a first slide surface configured to support a curtain carrier;

a second rail including a second slide surface configured to support a curtain carrier; and

a connector positioned between the first rail and the second rail, the connector including a first end having a first flange engaged with the first rail, a second end opposite the first end, the second end having a second flange engaged with the second rail, wherein the second end is separated from the first end by a gap defining a predefined distance between the first slide surface and the second slide surface, a body extending between the first end and the second end, and a ramp having a length greater than the predefined distance, the ramp including a first angled portion located adjacent to the first slide surface of the first rail, a second angled portion located adjacent to the second slide surface of the second rail, and a center portion extending between the first angled portion and the second angled portion, the center portion located adjacent to the gap, wherein a gap surface extends between the body and an inner surface of the ramp such that the gap surface, the body, and the inner surface of the ramp define a groove; and

wherein the connector is configured such that when a curtain carrier is mounted on the curtain support assembly and moving along a curtain travel path between the first rail and the second rail, the curtain carrier is supported by the ramp.

13 . The curtain support assembly of claim 12 , wherein the first slide surface of the first rail is aligned with the second slide surface of the second rail.

14 . The curtain support assembly of claim 12 , wherein the first rail includes a first end and a second end opposite the first end, the first slide surface extending between the first end of the first rail and the second end of the first rail, wherein the first flange is coupled to the first end of the first rail.

15 . The curtain support assembly of claim 14 , wherein the first angled portion defines an inclined surface extending from the first slide surface proximate to the first end of first rail to the center portion of the ramp.

16 . The curtain support assembly of claim 14 , wherein the first end of the first rail and the first end of the connector are coupled together via a fastener.

17 . The curtain support assembly of claim 14 , wherein the first end of the first rail defines an opening, and wherein the first flange is received and retain in the opening.

18 .
