Abstract
A scaffold assembly permits a single individual to install the assembly on an open stud wall. The assembly includes a horizontally oriented walkway supporting member, a vertically oriented rail support member, and a support unit extending from the walkway supporting member to the ground. An attachment assembly is connected to the walkway supporting member and includes a pair of rotatable members, one of which bears against the outer edges of a pair of adjacent studs and the other of which bears against the inner edges of the adjacent pair of studs in order to secure the scaffold assembly in place.
Claims3
A method for a single individual to install a scaffold support assembly on an open stud wall, the wall including
- an inner side,
- an outer side,
- a plurality of vertically oriented studs each spaced apart a selected distance from an adjacent one of said studs and having an upper end, an outer edge on the outer side of the wall, and an inner edge on the inner side of the wall,
- a horizontally oriented plate extending between the upper ends of the studs and having an inside edge on the inner side of the wall and an outside edge on the outer side of the wall,
- the method comprising the steps of
- (a) providing a unitary scaffold assembly including
- (i) a first horizontally oriented elongate platform support member having a proximate end and a distal end,
- (ii) a second vertically oriented elongate rail supporting member having an upper end and a lower end connected to said distal end of said first member,
- (iii) a third vertically oriented elongate support member unit connected to said proximate end of said first member and extending upwardly and downwardly from said first support member, said third member including an upper end and a lower end,
- (iv) a fourth member connected to and extending outwardly from said upper end of said third member and shaped and dimensioned to slip from the inner side of the wall over the horizontally oriented plate;
- (v) a fifth member rotatably mounted on said lower end of said third member below said first member and having a length greater than said selected distance,
- said fifth member movable between at least two operative positions,
- (vii) a first operative position generally coplanar with said first, second, third, and fourth members, and
- (viii) a second operative position generally perpendicular to said first, second, third, and fourth members;
- said first, second, third, fourth and fifth members generally collectively lying in a common plane when said fifth member are in said first operative position;
- (b) positioning said scaffold assembly on the inner side of the stud wall with said fifth member in said first operative position;
- (c) moving said scaffold assembly between a selected adjacent pair of studs toward the outer side of the stud wall;
- (d) positioning said scaffold assembly such that said fourth member engages and slides from the inner side of the stud wall over horizontally oriented plate, said fourth member extending over the inside edge of the horizontally oriented plate;
- and,
- (e) rotating said fifth member to said second operative position on the outer side of the wall and contacting the outside edges of the selected adjacent pair of studs.
