Abstract

A curtain wall system includes a vertical member and a horizontal member coupled to the vertical member at a joint. A vertical bridge gasket is coupled to the vertical member and includes a vertically-extending interior gasket, a vertically-extending thermal break gasket, and a vertical bridge member extending between the vertically-extending interior and thermal break gaskets. A horizontal bridge gasket is coupled to the horizontal member and joined to the vertical bridge gasket at a corner joint, the horizontal bridge gasket includes a horizontally-extending interior gasket, a horizontally-extending thermal break gasket, and a horizontal bridge member extending between the horizontally-extending interior and thermal break gaskets. The vertical and horizontal bridge gaskets cover the joint between the vertical and horizontal members.

First claim

What is claimed is:

1 . A curtain wall system, comprising:
a vertical member; a horizontal member coupled to the vertical member at a joint; a vertical bridge gasket coupled to the vertical member and including:
a vertically-extending interior gasket;
a vertically-extending thermal break gasket; and
a vertical bridge member extending between the vertically-extending interior and thermal break gaskets; and
a horizontal bridge gasket coupled to the horizontal member and joined to the vertical bridge gasket at a corner joint, the horizontal bridge gasket including:
a horizontally-extending interior gasket;
a horizontally-extending thermal break gasket; and
a horizontal bridge member extending between the horizontally-extending interior and thermal break gaskets;
wherein the vertical and horizontal bridge gaskets cover the joint between the vertical and horizontal members.

2 . The curtain wall system of claim 1 , wherein the vertical member defines a first vertical channel and a second vertical channel, and the horizontal member defines a first horizontal channel and a second horizontal channel, and wherein:
the vertically-extending interior gasket is coupled to the first vertical channel; the vertically-extending thermal break gasket is coupled to the second vertical channel; the horizontally-extending interior gasket is coupled to the first horizontal channel; and the horizontally-extending thermal break gasket is coupled to the second horizontal channel.

3 . The curtain wall system of claim 2 , further comprising a glazing panel mounted adjacent the vertical and horizontal members, wherein the vertically-extending interior gasket interposes the vertical member and the glazing panel, and the horizontally-extending interior gasket interposes the horizontal member and the glazing panel.

4 . The curtain wall system of claim 2 , wherein the vertical member provides a vertical tongue that defines the second vertical channel, and the horizontal member provides a horizontal tongue that defines the second horizontal channel.

5 . The curtain wall system of claim 4 , further comprising:
a first pressure plate secured to the vertical tongue with a first fastener, wherein the vertically-extending thermal break gasket interposes the first pressure plate and the vertical tongue; and a second pressure plate secured to the horizontal tongue with a second fastener, wherein the horizontally-extending thermal break gasket interposes the second pressure plate and the horizontal tongue.

6 . The curtain wall system of claim 2 , further comprising:
a vertical tongue extending from the vertical member; a first thermal tongue extension interposing the vertically-extending thermal break gasket and the vertical tongue, wherein the second vertical channel is defined in the first thermal tongue extension; a horizontal tongue extending from the vertical member; and a second thermal tongue extension interposing the horizontally-extending thermal break gasket and the horizontal tongue, wherein the second vertical channel is defined in the second thermal tongue extension.

7 . The curtain wall system of claim 2 , further comprising:
a first vertical dart extending along at least a portion of the length of the vertically-extending interior gasket and received within the first vertical channel; a second vertical dart extending along at least a portion of the length of the vertically-extending thermal break gasket and received within the second vertical channel; a first horizontal dart extending along at least a portion of the length of the horizontally-extending interior gasket and received within the first horizontal channel; and a second horizontal dart extending along at least a portion of the length of the horizontally-extending thermal break gasket and received within the second horizontal channel.

8 . The curtain wall system of claim 1 , wherein the vertical bridge member is angled by about 90° to extend to each of the vertically-extending thermal break and interior gaskets, and
wherein the horizontal bridge member is angled by about 90° to extend to each of the horizontally-extending thermal break and interior gaskets.

9 . The curtain wall system of claim 1 , wherein the vertical bridge gasket is a first vertical bridge gasket, and the horizontal bridge gasket is first horizontal bridge gasket, the curtain wall system further comprising:
a second vertical bridge gasket laterally offset from the first vertical bridge gasket and including:
a vertically-extending interior gasket;
a vertically-extending thermal break gasket; and
a vertical bridge member extending between the vertically-extending interior and thermal break gaskets of the second vertical bridge gasket; and
a horizontal bridge gasket vertically-offset from the first horizontal bridge gasket and including:
a horizontally-extending interior gasket;
a horizontally-extending thermal break gasket; and
a horizontal bridge member extending between the horizontally-extending interior and thermal break gaskets of the second horizontal bridge gasket;
wherein the first and second horizontal bridge gaskets extend between the first and second vertical bridge gaskets, and wherein each end of the first and second horizontal bridge gaskets is joined to a corresponding end of the first and second vertical bridge gaskets at corresponding corner joints to form a four-sided frame.

10 . A curtain wall frame gasket, comprising:
first and second vertical bridge gaskets laterally-offset from each other, each vertical bridge gasket including:
a vertically-extending thermal break gasket;
a vertically-extending interior gasket; and
a vertical bridge member extending between the vertically-extending thermal break and interior gaskets; and
first and second horizontal bridge gaskets vertically-offset from each other, each horizontal bridge gasket including:
a horizontally-extending thermal break gasket;
a horizontally-extending interior gasket; and
a horizontal bridge member extending between the horizontally-extending thermal break and interior gaskets;
wherein the first and second horizontal bridge gaskets extend between the first and second vertical bridge gaskets, and wherein each end of the first and second horizontal bridge gaskets is joined to a corresponding end of the first and second vertical bridge gaskets at corresponding corner joints to form a four-sided frame.

11 . The curtain wall frame gasket of claim 10 , further comprising:
a first relief defined in the first horizontal bridge gasket; and a second relief defined in the second horizontal bridge gasket and vertically-aligned with the first relief.

12 . The curtain wall frame gasket of claim 10 , wherein each corner joint of the corresponding corner joints forms a 90° angle between each end of the first and second horizontal bridge gaskets and the corresponding end of the first and second vertical bridge gaskets.

13 . The curtain wall frame gasket of claim 10 , further comprising:
a first vertical dart extending along at least a portion of the length of the vertically-extending thermal break gasket; a second vertical dart extending along at least a portion of the length of the vertically-extending interior gasket; a first horizontal dart extending along at least a portion of the length of the horizontally-extending thermal break gasket; and a second horizontal dart extending along at least a portion of the length of the horizontal -extending interior gasket.

14 . The curtain wall frame gasket of claim 13 , further comprising one or more barbs defined on one
