  • Patent number: 10494865
    Abstract: A safety apparatus for coupling with a ladder and methods for manufacturing and using same. The safety apparatus includes an engagement member defining an engagement member recess for receiving a selected structure and a retention member rotatable relative to the engagement member such that the retention member extends distally from the engagement member in an open position and extends proximally to the engagement member in a closed position. The retention member transitions from the open position to the closed position for enclosing the selected structure within the engagement member recess when weight is applied to the ladder and transitions from the closed position to the open position for releasing the selected structure when the weight is removed from the ladder. The ladder advantageously can inhibit unexpectedly detachment from the selected structure during use and does not require manual disengagement of the selected structure after use is complete.

  • Patent number: 5099952
    Abstract: A ladder lateral extension, adapted for use with a conventional ladder, includes a generally channel-shaped member adapted to be placed on the siderail of a ladder, such that the siderail fits within the channel-shaped member. The channel-shaped member has opposite interior and exterior sidewalls and a base. A pair of rung-receiving slots are formed in the exterior sidewall, which slots receive the rungs as the channel-shaped member is placed over the siderail. Extending perpendicularly outwardly from the exterior sidewall is a lateral support member of a length equal to or greater than the distance between the rung-receiving slots, thus providing a safe standing area. Safety for the user of the lateral ladder extension is thus greatly increased, due to the engagement of two rungs of the ladder and the length of the lateral support member, which allows the user to safely stand upon it.

  • Patent number: 4862994
    Abstract: A selectively removable support platform is designed to be attached to the rungs of a conventional ladder. The platform includes pivotally interconnected arms which may be aligned with the hollow metallic rungs of the ladder, and connector pins pivotally attached to the arms may then be projected through apertures in the arms so as to be positioned within the rung interiors. Safety straps may then be used to lock the connectors in position, and platform alignment is facilitated through the use of a telescoping adjustable arm construction. Short safety chains may optionally be provided for connecting the platform to a gutter spout or some other building structure, and the front of the platform is covered with a rubber or foamed plastic material so as to prevent both slippage and damage to the structure against which the platform is resting. Additionally, the foam or rubber material provides an electrically insulative effect between the ladder platform and metal siding.

  • Patent number: 4303145
    Abstract: A dual purpose ladder attachment usable singularly as a human body support platform with hand rails or in a pair as a scaffold jack. Each ladder attachment comprises two pairs of pivotally joined support beams. Each pair of pivotally joined support beams have their non-joined ends connected to ladder rung engaging brackets. Each bracket is sized and shaped to fit over the side rail of the ladder while engaged with a ladder rung. When the device is being used as a body support platform, a cross-bar connected between the parallel support beams supports a rigid planar surface which is also attached to a ladder rung. This platform is useful for standing on the ladder while holding the side rails. In this configuration the device is mounted to extend vertically upward on the upper side of the ladder, allowing a user to stand comfortably on the ladder.
