A portable, collapsible brace for mounting scaffolding on the side of a building, comprises a generally "U"-shaped structure made up of two bent arms, each comprising an upright, surface-engaging section having an oblique section at its lower end. The upright sections are spaced from each other by a standard building wall stud spacing and can be nailed to the studs. The oblique sections are connected to each other at a point between the stud locations. An arm is pivotally connected to this point, and is removably engageable with a platform pivoted to the upright sections. The platform is also generally U-shaped, and nests inside the attachment arm structure in coplanar relationship therewith when the apparatus is collapsed.

[ What is claimed is:] [1.] A scaffolding brace which may be secured flush to a surface of a support comprising:a pair of rigid attachment arms each having an elongated, surface-engaging section having upper and lower ends, and a bearing section extending from the lower end of its surface-engaging section, the surface-engaging sections having substantially coplanar surface-engaging faces and extending in parallel lines, the surface-engaging sections being in opposed relationship to each other and being spaced from each other so that an open space is provided between them, and the bearing sections extending toward, and being attached to, each other at an intermediate location between said parallel lines;a locking arm pivotally connected to the bearing sections at said intermediate location;a platform pivotally connected to the surface engaging sections of the two attachment arms, the platform being movable from a collapsed position in which it is substantially coplanar with the attachment arms to an extended position in which it projects outward in transverse relation to the attachment arms; andmeans for releasably engaging the locking arm with the platform to support the platform in said extended position.
