Abstract

A window wall system includes a sill receptor secured to an upper surface of a first floor slab, the sill receptor providing a base and an upright member extending from the base, a head receptor secured to a bottom surface of a second floor slab vertically offset from the first floor slab, and a glazing unit providing a sill, a head, and one or more panels extending between the sill and the head. A first hook defined by the sill is engageable with the upright member. When the upright member is received by the hook, the glazing unit is pivotable about the upright member toward a vertical orientation. A second hook is defined by the sill and receivable within a groove defined in the sill receptor when the glazing unit reaches the vertical orientation.

First claim

What is claimed is:

1 . A window wall system, comprising:
a sill receptor secured to an upper surface of a first floor slab, the sill receptor providing a base and an upright member extending from the base; a head receptor secured to a bottom surface of a second floor slab vertically offset from the first floor slab; a glazing unit providing a sill, a head, and one or more panels extending between the sill and the head; a first hook defined by the sill and engageable with the upright member, wherein the first hook extends downward and thereby defines a downwardly-opening channel sized to receive the upright member such that the glazing unit is pivotable about the upright member toward a vertical orientation; and a second hook defined by the sill and receivable within a groove defined by the upright member in the sill receptor when the glazing unit reaches the vertical orientation, wherein the groove extends substantially parallel to the base.

2 . The window wall system of claim 1 , wherein the upright member extends perpendicular from the base.

3 . The window wall system of claim 1 , wherein receiving the upright member in the channel prevents the glazing unit from migrating toward an exterior or interior environment.

4 . The window wall system of claim 1 , further comprising a spring clip operable to prevent the head from exiting the head receptor once the head is received within the head receptor and the glazing unit reaches the vertical orientation.

5 . The window wall system of claim 4 , wherein the spring clip is mounted to the head.

6 . The window wall system of claim 4 , wherein the spring clip is mounted to the head receptor.

7 . The window wall system of claim 4 , wherein the spring clip provides a spring-loaded biasing member configured to locate a pocket when the glazing unit reaches the vertical orientation, and wherein the spring-loaded biasing member engages an obstruction within the pocket that prevent the head from exiting the head receptor.

8 . A method of installing a glazing unit of a window wall system, comprising:
securing a sill receptor to an upper surface of a first floor slab, the sill receptor providing a base and an upright member extending from the base; securing a head receptor secured to a bottom surface of a second floor slab vertically offset from the first floor slab; receiving the glazing unit between the first and second floor slabs, the glazing unit including a sill, a head, and one or more panels extending between the sill and the head; receiving the upright member within a downwardly-opening channel defined by a first hook defined by the sill and pivoting the glazing unit about the upright member and toward a vertical orientation; and receiving a second hook defined by the sill within a groove defined by the upright member in the sill receptor when the glazing unit reaches the vertical orientation, wherein the groove extends substantially parallel to the base.

9 . The method of claim 8 , wherein receiving the upright member within a downwardly-opening channel comprises:
receiving the upright member in the channel and thereby preventing the glazing unit from migrating toward an exterior or interior environment.

10 . The method of claim 8 , further comprising preventing uplift of the glazing unit by receiving the second hook within the groove.

11 . The method of claim 8 , further comprising securing the glazing unit to the sill receptor without mechanical fasteners.

12 . The method of claim 8 , wherein pivoting the glazing unit toward the vertical orientation further comprises:
locating a spring-loaded biasing member of a spring clip in a pocket once when the glazing unit reaches the vertical orientation; and engaging the spring-loaded biasing member against an obstruction within the pocket and thereby preventing the head from exiting the head receptor.

13 . A window wall system, comprising:
a sill receptor secured to an upper surface of a first floor slab, the sill receptor providing a base and an upright member extending from the base; a glazing unit providing a sill; a first hook defined by the sill, wherein the first hook extends downward and thereby defines a downwardly-opening channel sized to receive the upright member; and a second hook defined by the sill and receivable within a groove defined by the upright member in the sill receptor, wherein the groove extends substantially parallel to the base.

14 . The window wall system of claim 13 , wherein the glazing unit further provides a head, and wherein the window wall system further comprises:
a head receptor secured to a bottom surface of a second floor slab vertically offset from the first floor slab; and a spring clip operable to prevent the head from exiting the head receptor once the head is received within the head receptor.

15 . The window wall system of claim 14 , wherein the spring clip is mounted to the head.

16 . The window wall system of claim 14 , wherein the spring clip is mounted to the head receptor.
