Abstract: The bracket 6 of the rod holder 2 is constructed of substantially resiliently flexible material and has four slots 24, 26, 28 and 30 in the rim 18 thereof, which depend to points 37 substantially contiguous to the base plate 4, so that the bracket is divided into pairs of relatively resiliently displaceable body portions 38, 40, 42, 44, and 46. The walls 36 of the body portions have successive pairs of part annular collar sections 34 therein, which define successively smaller clamping rings 48, with nips 50 therebetween, as the slots depend toward the plate 4. As a result, when a rod 96 is impaled in the V-shaped kerf of a slot, it can seek that ring 48 which will grip it against dislodgement, when the caduceus-like clamps 32 at the walls of the body portions, relax about the rod.

Abstract: The invention relates to a vertically and horizontally movable work platform 4 for carrying out renovations to the concrete on reinforced concrete buildings or for replacing the structural protection on steel constructions. To increase the operational safety these work platforms 4 are held against the surfaces 1 of the buildings by attached magnetic plates 6. Since the tensions cables previously required are dispensed with, the weight of the upper carriage 2 from which the work platforms are suspended by cables is considerably reduced.

Abstract: A pair of attachments for use with ladders constructed with hollow rungs to stabilize the ladder and to protect the gutter. These attachments when used with ladders also provide for a scaffold plank. The attachments when used with a ladder on a pitched roof allows the ladder to be used to access that roofs peak. Previously the ladder would rest on the rain gutter when the user was to access the roof of a building. Previously a work platform had to be built from wood or metal resulting in time consuming construction. Previously when accessing the roof peak of a building a means of providing a positive foothold had to be constructed from rope and ladder or from wood. The present invention provides steel flat bars bent to fit the rung spacing of the ladder with a steel tube welded at each end sized to fit snuggly into the opening of any two consecutive rungs in that ladder. The ladder can now be used to access the roof of a building without resting on the gutter.
