Definitions
- the present invention belongs to a class of mounting clips that are useful in the construction of buildings, particularly commercial buildings where a non-load bearing, exterior curtain wall is connected to the load bearing elements of a building and the curtain wall needs to be able to move with respect to the load bearing elements.
- curtain walls systems it is often advantageous to attach curtain walls systems to the load bearing elements of a building with connectors that permit a degree of relative movement between the wall system and other components of the building.
- curtain walls are typically not designed to support the vertical loads in the structure and must therefore by isolated from deflection of the primary load-bearing support structure of the building due to changes in live or dead loads carried by that structure. Providing a degree of freedom of movement within the wall and between the wall and the other components of a building can reduce stress and prevent fracture of connected parts due to the loading of the building, seismic and wind events, or differences in the
- US Patent 5,876,006, issued in 1999 to Terry L. Sharp and Richard C. Eldenburg also teaches a mounting clip where a spacer or fixed bracket is connected to the supported member and the mounting clip is attached to the supporting member and the fixed bracket in such a manner that the mounting clip can move with respect to the supported member.
- a spacer or fixed bracket is connected to the supported member and the mounting clip is attached to the supporting member and the fixed bracket in such a manner that the mounting clip can move with respect to the supported member.
- Sharp and Eldenburg taught that the fixed bracket should have an engaging component received by the portion of the mounting clip lying against the supported member that is thicker than the receiving portion of the mounting clip.
- a planar securing component which is attached to the engaging component should extend in parallel relation over the receiving portion of the mounting clip.
- Patents with similar teachings include US Patent 6,213,679, issued in 2001 to Frobosilo and Viola, and US Patent 5,906,080, issued in 1999 to diGirolamo and Mountcastle.
- US Patent 7,104,024, which issued in 2006 to diGirolamo et al, teaches having the spacers that allow for sliding motion of the mounting clip to also be connected to a u-shaped, reinforcing member that adds strength and rigidity to the connection.
- the mounting clip of the present invention provides a uniquely shaped clip and slider that help to prevent the mounting clip from buckling under load.
- the present invention provides a drift clip that has a unique shape to avoid buckling of the clip under load.
- the present invention provides a mounting clip with a unique shape that has a unique slider that is used in one or more elongated slots in the clip to provide improved rotational support to the mounting clip and thereby avoid buckling of the mounting clip.
- the slider has a securing component, and the securing component has one or more generally planar upstanding flanges connected to and set at an angle to the one or more base components, such that a projection along the generally planar upstanding flange would intersect with the leg of the mounting clip to which it is attached.
- This tall flange disposed at an angle to the leg of the mounting clip to which it is attached improves the strength of the securing component.
- the present invention provides a connection, including a supporting member, a supported member, and a connector.
- the connector attaches the supported member to the supporting member.
- the connector includes a mounting clip and one or more sliders and the mounting clip is retained with respect to the one or more sliders so that the mounting clip can move relative to the one or more sliders.
- the mounting clip has an anchored leg disposed in close proximity to the supported member.
- the anchored leg has a front surface and a back surface on opposite sides of the anchored leg with the back surface of the anchored leg facing the supported member.
- the anchored leg also has one or more openings.
- An anchoring leg is connected to the anchored leg and disposed in close proximity to the supporting member.
- the anchoring leg has a sliding surface and an interfacing surface on opposite sides of the anchoring leg with the interfacing surface of the anchoring leg facing the supporting member.
- the anchoring leg also has one or more openings.
- the one or more sliders have one or more base components that are received in at least one of the one or more openings of the anchored leg and the one or more openings of the anchoring leg.
- the one or more openings that receive the one or more base components are larger than the one or more base components so that the one or more base components can move with respect to the one or more openings.
- Each of the one or more slides also has a securing component that is attached to the one or more base components.
- the securing component has one or more containment surfaces that are disposed in close proximity to at least one of the front surface of the anchored leg when the one or more base components are received in the one or more openings of the anchored leg and the sliding surface of the anchoring leg when the one or more base components are received in the one or more openings of the anchoring leg.
- the containment surfaces prevent the mounting clip from pulling away from either the supporting member or the supporting member, depending on which member is attached to the slider.
- the securing component can have one or more upstanding flanges connected to and set at an angle to the one or more base components extending substantially above the one or more base components.
- one or more fasteners connect the one or more sliders to at least one of the supporting member and the supported member.
- the slider can be a unitary member.
- the base members are elongated members with multiple points of contact along the one or more openings.
- the one or more upstanding flanges have an outer edge and one or more bottom edges that are generally opposed to the outer edges and the containment surfaces are formed on the one or more bottom edges of the flanges.
- the one or more bottom edges of the one or more flanges are interrupted by one or more projecting arms that extend to and connect the one or more upstanding flanges to the one or more base components.
- the projecting arms are narrower than both the one or more base components and the one or more flanges.
- the one or more upstanding flanges are formed with lateral bends or embossments to provide additional strength to the flanges.
- the one or more upstanding flanges are generally parallel to each other, and the one or more upstanding flange are disposed generally orthogonally to the base components.
- the mounting clip can be formed so that one of the anchoring leg and the anchored leg is a unitary member having opposed side edges and the other of the anchoring leg and the anchored leg is made of two overlapping members each of which is joined to one of the opposed side edges of the unitary member and are then bent so as to overlap.
- each of the overlapping members is formed with a side flange that is connected to one of the opposed side edges of the unitary member at a bend line, and each of the overlapping members is formed with a back flange connected to the side flange at a bend line, and the back flanges overlap.
- each of the back flanges are formed with one opening and the back flanges overlap in such a manner that a single opening is formed for receiving the one or more base members of the one or more sliders.

This is typically vertical movement, horizontal movement or a combination of vertical and horizontal movement between the supporting and the supported members 2 and 3 depending upon the features of the mounting clip 4. A change in orientation of the components of the connection 1 would allow the connector 8 to permit different relative movements between the components.
