    Abstract: A collapsible platform assembly for an extension ladder is disclosed that can be used to support the top of an extension ladder with respect to a roof. The collapsible platform assembly includes a platform that is rotatably connected to a rung of an extension ladder near the top. In a storage or retracted position, the platform is generally co-planar with the ladder; i.e fits between the side rails of the extension ladder. In a use position, the platform can be extended and directly supported by the roof, either flat against a roof or alternatively at an acute angle relative to the roof. Since the platform is configured to be directly supported by the roof, the platform acts as a rigid support for the top of the ladder which does not deflect under load as there is an even weight transfer from the ladder to the platform in use.

  • Patent number: 6945359
    Abstract: A sleeve is disclosed for a leg of a ladder. The sleeve includes a length of generally “U”-shaped cross-sectional material, and the sleeve slides over an end of the leg of the ladder. Each rung of the ladder slides along an open portion of the generally “U”-shaped cross-section as the sleeve is slid over and along the leg of the ladder. When the ladder rests against an object, the sleeve can be longitudinally adjusted along the leg to reduce marring the object from contact by the leg of the ladder.

  • Patent number: 6942063
    Abstract: In combination with an extension ladder, an L-shaped bracket is provided. The bracket has at least one first leg longer than the distance between successive rungs of the ladder. The first leg is placed on one side of an upper rung and on the other side of a next lower rung. A short leg integral with the first leg projecting generally at right angles to the first leg, is placed on top of the upper rung and extends beyond the rung. It is adapted to support an accessory, such as a paint can or a tray. A clamp on the projecting leg insures against dislodgement of the holder. In the preferred embodiment, two L-shaped brackets are connected to an accessory carrying bar that projects beyond the sides of the rails of the ladder, and the clamp includes a plate wedging between the bar and a rail of the ladder.

  • Patent number: 6929095
    Abstract: The roll-up stabilizer includes an elongated aluminum stabilizer bar that is square in cross-section. The bar is U-shaped and is bent at both ends to form the arms of the “U”. Each arm has a curved portion and a straight portion. An axle for a wheel is welded or otherwise attached to the end of the straight portion of each arm and a wheel is rotatably secured to each axle. A sheet metal trough is affixed to the central part of the middle portion of the bar by welding or other suitable fasteners. The trough is shaped to hook over and center the stabilizer bar upon the top rung of a ladder. Toggle clamps are secured by welding or other suitable fasteners to the stabilizer bar or to tubular sliding members on the stabilizer bar in position to secure the bar to the base of a ladder rail that is I-shaped in cross-section in a position adjacent the top rung of the ladder.
