Abstract

A construction section for supporting a glass panel and configured to be coupled to a building structure. The construction section may comprise a wood mullion, an upper fitting, and a gravity fitting. The wood mullion may comprise an elongate body, a pair of cutouts in the upper and lower ends, and upper and lower pockets. The elongate body may comprise an exterior face, an upper end, and a lower end. The pair of cutouts in the upper and lower ends may be configured to receive at least a portion of the building structure. The upper and lower pockets may comprise a void area within the elongate body adjacent the exterior face. The upper fitting may be configured to support at least a portion of the glass panel. The gravity fitting may be coupled within the lower pocket and configured to support at least a portion of the glass panel.

Claims (49)

1 . A construction section for supporting a glass panel and configured to be coupled to a building structure, comprising:

a solid wood mullion comprising:

an elongate body having an exterior face, an upper end, and a lower end;

a pair of cutouts located in the upper and lower ends configured to receive at least a portion of the building structure;

an upper pocket having an upper void area recessed within the elongate body adjacent the exterior face; and

a lower pocket having a lower void area recessed within the elongate body adjacent the exterior face;

an upper fitting coupled within the upper pocket and configured to support at least a first portion of the glass panel, the upper fitting comprising:

an inner fitting;

an outer fitting;

a first fastener configured to couple the inner fitting to the upper pocket; and

a second fastener configured to couple the inner fitting to the outer fitting;

a gravity fitting coupled within the lower pocket and configured to support at least a second portion of the glass panel, the gravity fitting comprising:

a panel support extending substantially horizontally and perpendicular to the exterior face of the mullion, the panel support configured to vertically support the glass panel;

a support arm coupled to the panel support and extending substantially vertically therefrom; and

a third fastener configured to couple the gravity fitting to the lower pocket.

2 . The construction section of claim 1 , wherein an interior surface of the glass panel is spaced apart from the exterior face of the wood mullion by a gap.

3 . The construction section of claim 1 , wherein an interior surface of the glass panel is spaced apart from the exterior face of the wood mullion by the inner fitting.

4 . The construction section of claim 1 , wherein the first, second, and third fasteners comprise a stud and cap nut.

5 . The construction section of claim 1 , wherein the upper and lower pockets each contain an aperture that receives an insert configured to couple the first and third fasteners.

6 . The construction section of claim 5 , wherein the insert is a metal tapped insert having internal threads that receive the first and third fasteners.

7 . The construction section of claim 1 , wherein the panel support vertically supports the glass panel.

8 . The construction section of claim 7 , wherein the panel support is coupled to a lower portion of the support arm and is located substantially horizontal and perpendicular to the support arm.

9 . The construction section of claim 8 , wherein the support arm is oriented substantially parallel to the exterior face of the mullion.

10 . The construction section of claim 9 , wherein the support arm comprises a mating surface with a raised portion configured to fit within the void area of the lower pocket.

11 . A construction system configured to be coupled to a building structure, comprising:

a glass panel;

a solid wood mullion comprising:

an elongate body having an exterior face, an upper end, and a lower end;

a pair of cutouts located in the upper and lower ends configured to receive at least a portion of the building structure;

an upper pocket having an upper void area recessed within the elongate body adjacent the exterior face; and

a lower pocket having a lower void area recessed within the elongate body adjacent the exterior face;

an upper fitting coupled within the upper pocket and configured to support at least a first portion of the glass panel, the upper fitting comprising:

an inner fitting;

an outer fitting;

a first fastener configured to couple the inner fitting to the upper pocket; and

a second fastener configured to couple the inner fitting to the outer fitting;

a gravity fitting coupled within the lower pocket and configured to support at least a second portion of the glass panel, the gravity fitting comprising:

a panel support extending substantially horizontally and perpendicular to the exterior face of the mullion, the panel support configured to vertically support the glass panel;

a support arm coupled to the panel support and extending substantially vertically therefrom; and

a third fastener configured to couple the gravity fitting to the lower pocket.

12 . The construction system of claim 11 , wherein an interior surface of the glass panel is spaced apart from the exterior face of the wood mullion by a gap.

13 . The construction system of claim 11 , wherein an interior surface of the glass panel is spaced apart from the exterior face of the wood mullion by the inner fitting.

14 . The construction system of claim 11 , wherein the first, second, and third fasteners comprise a stud and cap nut.

15 . The construction system of claim 11 , wherein the upper and lower pockets each contain an aperture that receives an insert configured to couple the first and third fasteners.

16 . The construction system of claim 15 , wherein the insert is a metal tapped insert having internal threads that receive the first and third fasteners.

17 . The construction system of claim 11 , wherein the panel support vertically supports the glass panel.

18 . The construction system of claim 17 , wherein the panel support is coupled to a lower portion of the support arm and is located substantially horizontal and perpendicular to the support arm.

19 . The construction system of claim 18 , wherein the support arm is oriented substantially parallel to the exterior face of the mullion.

20 . The construction system of claim 19 , wherein the support arm comprises a mating surface with a raised portion configured to fit within the void area of the lower pocket.
