Toggle assembly for retaining a panel member
View Patent ↗The present invention relates to a toggle assembly that can be used with a curtain wall system to retain infills of panel members. A toggle assembly of the present invention is sufficiently designed to simultaneously retain in place a first infill of a first panel member and a first infill of a second panel member on both sides of a mullion, wherein at least a portion of the toggle assembly directly engages at least a portion of the first infill of the first panel member and at least a portion of the first infill of the second panel member.
1. A toggle assembly comprising:
a toggle component comprising a clip and a spacer;
wherein the clip comprises a base, a left face, and a right face,
wherein the base has an upper surface engaging the spacer and a lower surface,
wherein the left face comprises an outer surface and an inner surface,
wherein the right face comprises an outer surface and an inner surface,
wherein a left-side track forms at a junction between the lower surface of the base and the inner surface of the left face,
wherein a right-side track forms at a junction between the lower surface of the base and the inner surface of the right face,
wherein the left face terminates in a left engagement leg, wherein the right face terminates in a right engagement leg, and
wherein the spacer is substantially shaped as a hollow cylinder having a first end engaging the upper surface of the base and a second end,
wherein the spacer has a first internal radius at the first end that is larger than a second internal radius at the second end, and
wherein an internal circular ridge is created at a junction between the first internal radius and the second internal radius; and
a support reinforcement bar,
wherein the support reinforcement bar is sized and dimensioned to fit within a space created between the lower surface of the base, the inner surface of the left face, and the inner surface of the right face,
wherein the support reinforcement bar comprises a left lip that engages with the left-side track of the toggle component and a right lip that engages with the right-side track of the toggle component, and
wherein the engagement leg of the left face and the engagement leg of the right face are sufficiently designed to maintain the support reinforcement bar within the clip of the toggle component.
2. The toggle assembly of claim 1 wherein the toggle component is manufactured from a polymer material.
3. The toggle assembly of claim 2 wherein the toggle component is manufactured from acrylonitrile butadiene styrene (ABS).
4. The toggle assembly of claim 1 wherein the base is shaped like a parallelogram having two angles of approximately 60° and two angles of approximately 120°.
5. The toggle assembly of claim 1 wherein the support reinforcement bar is manufactured from a corrosion-resistant material selected from the group consisting of metals, ceramics and polymers.
6. The toggle assembly of claim 1 wherein the support reinforcement bar is manufactured from an aluminum alloy material.
7. The toggle assembly of claim 1 ,
wherein the upper surface of the base has a left end terminating in a left raised portion and a right end terminating in a right raised portion,
wherein the left face descends from the left raised portion of the base, and
wherein the right face descends from the right raised portion of the base.
8. The toggle assembly of claim 1 ,
wherein the toggle component includes a receiving hole configured to receive a fastener,
wherein the receiving hole comprises an entry end at the base and an exit end at the second end of the spacer, and
wherein the support reinforcement bar includes a receiving hole configured to receive a fastener.
9. The toggle assembly of claim 8 wherein an internal diameter of the entry end of the receiving hole is larger than an internal diameter of the exit end of the receiving hole.
10. The toggle assembly of claim 9 wherein the internal diameter of the entry end of the receiving hole is between about 0.250 inches and about 0.260 inches.
11. The toggle assembly of claim 9 wherein the internal diameter of the exit end of the receiving hole is between about 0.210 inches and about 0.220 inches.
12. The toggle assembly of claim 9 wherein an internal diameter of the receiving hole is substantially the same the internal diameter of the entry end of the receiving hole.
13. The toggle assembly of claim 9 wherein the internal diameter of the exit end of the receiving hole is sized so that, when a fastener is positioned through the receiving hole and the receiving hole, and the fastener is turned, threads of the fastener grab the circular ridge and rotate the toggle assembly.
14. A curtain wall glazing system comprising the toggle assembly of claim 1 .
