Unitary suspension clip for supporting demountable partition walls

An article of manufacture for support on a horizontal support member comprising:

• a) a plate having a back and a front;
• b) two substantially co-planar wings extending outwardly and downwardly from opposite sides of said plate;
• and
• c) a line of weakness between said plate and each of said wings forming a pivot point for rotation of each of said wings from said first substantially co-planar position to a second position projecting downwardly and outwardly from the back of said plate, one edge of each of said wings forming an acute angle relative to the back of said plate and for resting on the horizontal support member for demountably supporting said plate against gravity and drawing said plate toward the horizontal support member.

A method of erecting a demountable partition wall comprising the steps of:

• erecting a vertical support structure including a horizontal support member;
• affixing a suspension clip comprised of a plate having a plurality of panel-piercing members extending from one face thereof to a gypsum board panel by driving the panel-piercing members into the gypsum board panel;
• pivoting a wing formed in the edge of the plate and having a bearing surface along the edge of the wing from a first position substantially co-planar with the plate to a second position angled upwardly from the surface of the gypsum board panel, the bearing surface forming an acute angle relative to the edge of the plate;
• resting the bearing surface over the horizontal support member when the wing is in the second position to support the gypsum board panel to which the clip is affixed thereon;
• and
• translating downward movement of the clip relative to the horizontal support member resulting from the weight of the gypsum board panel into movement of the gypsum board panel toward the vertical support structure by sliding engagement of the horizontal member by the bearing surface.
