Abstract

A substantially vertically extending removable and replaceable cover and a substantially horizontally extending cover for use with a curtain wall system broadly comprising an array of windows, a set of vertical and horizontal mullions, a set of window gaskets. The covers overlay the mullions and each include a front side, left and right or top and bottom sides, and rear tabs extending therefrom for removably connecting the covers on the mullions.

Claims

1. A removable and replaceable cover for a vertically extending mullion of a curtain wall, the removable and replaceable cover comprising:

a first sidewall and a second sidewall for abutting first and second sidewalls of the vertically extending mullion, respectively, the first and second sidewalls of the removable and replaceable cover each including opposing proximal and distal ends and at least one opening configured to receive a shear block of a horizontally extending mullion therethrough, the opening extending to the proximal end such that the removable and replaceable cover is configured to be horizontally slid onto and off of the horizontally extending mullions;

a front wall extending between the distal ends of the first and second sidewalls of the removable and replaceable cover for covering a front wall of the vertically extending mullion, the front wall of the removable and replaceable cover including an aesthetic design including an etched, raised, pressed, or milled area; and

a first tab and a second tab extending from the proximal ends of the first and second sidewalls of the removable and replaceable cover, each tab being configured to abut a contour of the vertically extending mullion when the removable and replaceable cover is positioned on the vertically extending mullion and slide outwardly against the contour of the vertically extending mullion and spread the first sidewall and second sidewall of the removable and replaceable cover apart from each other until the first tab and second tab do not abut the contour of the vertically extending mullion when the removable and replaceable cover is pulled in a direction of the front wall of the removable and replaceable cover such that the removable and replaceable cover is removably connectable to the vertically extending mullion of the curtain wall.

2. The removable and replaceable cover of claim 1, wherein the removable and replaceable covet is formed of a material selected from the group consisting of zinc, copper, steel, stainless steel, brass, bronze, titanium, aluminum, plated metal, coated metal, and plastic.

3. The removable and replaceable cover of claim 1, wherein the removable and replaceable cover is formed of sheet metal.

4. The removable and replaceable cover of claim 3, wherein the removable and replaceable cover is formed from a single piece of sheet metal.

5. The removable and replaceable cover of claim 1, wherein the removable and replaceable cover is formed of molded plastic.

6. The removable and replaceable cover of claim 1, wherein the first and the second sidewall of the removable and replaceable cover each are configured to abut an end of one of the horizontally extending mullions.

7. The removable and replaceable cover of claim 1, wherein the removable and replaceable cover is interchangeable with another removable and replaceable cover having a front wall including a different aesthetic design.

8. The removable and replaceable cover of claim 1, wherein the side walls of the removable and replaceable cover include an aesthetic design.

9. The removable and replaceable cover of claim 1, wherein the front wall of the removable and replaceable cover has a convex contour.

11. The removable and replaceable cover of claim 1, wherein the opening is rectangular for receiving a rectangular shear block therethrough.

12. The removable and replaceable cover of claim 1, wherein the opening extends to ends of the tabs such that the removable and replaceable cover is configured to be horizontally slid onto and off of the horizontally extending mullions.

13. The removable and replaceable cover of claim 1, wherein the first tab and second tab extend from the first and second sidewalls of the removable and replaceable cover at air angle greater than 90 degrees.

10. A removable and replaceable cover for a vertically extending mullion of a curtain wall, the removable and replaceable cover comprising:

a first sidewall and a second sidewall extending parallel to the first sidewall for abutting first and second sidewalls of the vertically extending mullion, respectively, the first and second sidewalls of the removable and replaceable cover each including an aesthetic design, opposing proximal and distal ends, and at least one rectangular opening configured to receive a shear block of a horizontally extending mullion therethrough, the opening extending to the proximal end such that the removable and replaceable cover is configured to be horizontally slid onto and off of the horizontally extending mullions;

a front wall extending between the distal ends of the first and second sidewalls of the removable and replaceable cover for covering a front wall of the vertically extending mullion such that the first sidewall and the second sidewall of the removable and replaceable cover extend at 90 degree angles from the front wall of the removable and replaceable cover, the front wall of the removable and replaceable cover including an aesthetic design, the aesthetic design of the first and second sidewalls of the removable and replaceable cover and the aesthetic design of the front wall of the removable and replaceable cover each including an etched, raised, pressed, or milled area; and

a first tab and a second tab extending from the proximal ends of the first and second sidewalls of the removable and replaceable cover, each tab being configured to abut a contour of the vertically extending mullion when the removable and replaceable cover is positioned on the vertically extending mullion and slide outwardly against the contour of the vertically extending mullion and spread the first sidewall and second sidewall of the removable and replaceable cover apart from each other until the first tab and second tab do not abut the contour of the vertically extending mullion when the removable and replaceable cover is pulled in a direction of the front wall of the removable and replaceable cover such that the removable and replaceable cover is removably connectable to the vertically extending mullion of the curtain wall,

the removable and replaceable cover being formed of a material selected from the group consisting of zinc, copper, steel, stainless steel, brass, bronze, titanium, aluminum, plated metal, coated metal, and plastic, the removable and replaceable cover being further configured to revert to a pre-formed shape when the removable and replaceable cover is positioned completely over the vertically extending mullion such that the first and second tabs abut the proximal contours of the vertically extending mullion and retain the removable and replaceable cover on the vertically extending mullion.
