Abstract

Abstract A suspension assembly is provided for suspending gypsum board panels from a horizontal support member. The plate portion of the suspension assembly has panel piercing tangs of a novel twisted conformation projecting rearwardly to affix the plate to the panel. A narrow neck portion of the plate forms channel means to receive the upper portion of a separate suspension clip. The lower portion of the clip is inclined outwardly to engage the horizontal support member. A plurality of transverse lines of weakness comprising slots and notch means extending substantially across the width of the neck portion of the plate are designed such that when the gypsum board panel is suspended from the support member, the load applied between the clip and the plate causes the neck portion of the plate to bend outwardly from the panel along said lines of weakness, while the upper and lower plate portions remain affixed to the panel.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 244 words
A suspension assembly for suspending a gypsum board panel from a support member of a support structure, said suspension assembly comprising: a plate having upper and lower portions and a neck portion therebetween, a plurality of transverse lines of weakness in the neck portion comprising transverse slots extending substantially across the width of the plate and pairs of notch means cut into opposed side edges of the plate, each pair of notches being substantially in alignment with a transverse slot, a plurality of panel piercing tangs on the upper and lower plate portions extending substantially normal to one face of the plate, channel means formed by said neck portion having upper and lower open ends; and a suspension clip having upper and lower portions, and stop means therebetween, said upper portion being slidingly received in the channel means to engage the plate, said stop means being arranged to prevent upward extension of the upper clip portion past the neck portion of the plate, the lower clip portion overlying the lower plate portion, and said lower clip portion being inclined outwardly from the plane of the lower plate portion to engage the support member, whereby when the gypsum board panel is suspended from the support structure the load applied between the clip and the plate causes the neck portion of the plate to bend outwardly from the panel along said lines of weakness, while the upper and lower plate portions remain affixed to the panel.
Claim 2
Dependent Claim 244 words
A suspension assembly for suspending a gypsum board panel from a support member of a support structure, said suspension assembly comprising: a plate having upper and lower portions and a neck portion therebetween, a plurality of transverse lines of weakness in the neck portion comprising transverse slots extending substantially across the width of the plate and pairs of notch means cut into opposed side edges of the plate, each pair of notches being substantially in alignment with a transverse slot, a plurality of panel piercing tangs on the upper and lower plate portions extending substantially normal to one face of the plate, channel means formed by said neck portion having upper and lower open ends; and a suspension clip having upper and lower portions, and stop means therebetween, said upper portion being slidingly received in the channel means to engage the plate, said stop means being arranged to prevent upward extension of the upper clip portion past the neck portion of the plate, the lower clip portion overlying the lower plate portion, and said lower clip portion being inclined outwardly from the plane of the lower plate portion to engage the support member, whereby when the gypsum board panel is suspended from the support structure the load applied between the clip and the plate causes the neck portion of the plate to bend outwardly from the panel along said lines of weakness, while the upper and lower plate portions remain affixed to the panel.
Claim 3
Dependent Claim 96 words
The suspension assembly as set forth in claim 1 wherein: the neck portion of the plate has upper and lower parallel channel slots extending across a portion of the width of the plate, the upper and lower channel slots respectively defining the upper and lower open ends of the channel, said channel slots being vertically spaced to leave a portion of the plate lying between the channel slots which is pressed outwardly from the plane of the plate to form the channel means, and the lines of weakness are located above and below the channel means.
Claim 4
Dependent Claim 24 words
The suspension assembly as set forth in claim 1 or 2 wherein: the tangs are twisted inwardly toward a vertical centre of the plate.
