Abstract: A wallboard-fastening device for securing first and second wallboards in an inside-corner configuration includes a first framing panel having a first lengthwise edge and a second framing panel having opposite second and third lengthwise edges, the second lengthwise edge directly connecting to the first lengthwise edge. A first flat-spring flange having a fourth lengthwise edge is directly connected to the third lengthwise edge such that the first flat-spring flange, the first framing panel, and the second framing panel form a channel sized to accept the first wallboard. A second flat-spring flange having a fifth lengthwise edge is connected to the third lengthwise edge. The first flat-spring flange flexes, when the first wallboard is inserted into the channel, to push against the first wallboard, and the second flat-spring flange flexes, when a rear face of the second framing panel is pushed against the second wallboard, to push against the second wallboard.

Abstract: A wallboard-fastening device secures first and second wallboards to a framing member without fasteners passing through the wallboards. The device includes first, second, and third framing panels joined along lengthwise edges to form a three-sided cup sized to fit around the framing member, first and second flat-spring flanges joined along lengthwise edges to form a front seam, and a channel-dividing panel joined lengthwise to the front seam and to the second framing panel to form first and second channels that receive the first and second wallboards. The flat-spring flanges flex to exert restoring forces on the wallboards that push the wallboards against the second framing panel. The device may be configured for edge joints, outside-corner joints, and inside-corners, and thus may be combined for any type of wallboard installation, including both parallel and perpendicular applications.

Abstract: A wallboard fastening device secures first and second wallboards to a framing member without fasteners passing through the wallboards. The device includes first and second framing panels joined along lengthwise edges at a frame seam to form a two-sided frame that fits around the framing member. The device includes first and second flat-spring flanges joined along lengthwise edges at a front seam. The device includes a channel-dividing panel joined lengthwise to the front seam and to the second framing panel to form first and second channels that are sized to receive edges of the wallboards. The device includes a guide flange joined lengthwise to the frame seam. A corner edge of the second wallboard may be pushed against the guide flange such that the corner edge slides along the guide flange, thereby guiding the second wallboard into the second channel.
