Abstract
A stepladder platform which can be installed onto the steps of a stepladder to provide an enlarged standing area. A restraining means at the rear engages the stepladder step to prevent forward movement and tilting. A restraining means at the front prevents rearward movement. Also a latch device can be used to prevent tilting from the front. The platform is constructed to support the weight of a person standing on it.
Claims23
A stepladder platform constructed of rigid material for attachment to a stepladder of the type having a step formed of a channel cross-section member supported at left and right ends by stiles the step channel having a top channel wall, a rear channel wall and a front channel wall and which is open at the bottom comprising,
- a stepping platform adapted to be placed upon and supported by the top channel wall of the step channel, the stepping platform extending laterally forward and rearward of the forward and rearward edges of the top channel wall to provide a platform of sufficient lateral dimension and area for the sole and heel of the feet of a person standing thereon;
- at least one hookflange attached to the stepping platform and capable of co-acting with the rear channel wall to prevent forward lateral movement and tilting of the stepping platform.
A stepladder platform constructed of rigid material for attachment to a stepladder of the type having a step formed of a channel cross-section member supported at left and right ends by attachment to stiles, the step channel having a top channel wall, a rear channel wall and front channel wall and which is open at the bottom comprising;
- a stepping platform of generally rectangular shape adapted to be placed upon and supported at a central position by and laterally co-extensive with the top channel wall and having an inward portion extending inwardly beyond the central portion and having an outward portion extending outwardly beyond the central portion to provide a platform of sufficient dimension for both feet of a user;
- a hookflange attached to the stepping platform comprising a flange portion attached to and extending downwardly from the step platform substantially the entire width thereof and attached thereto at approximately the inner terminus of the central portion of the stepping platform, and a hook portion extending substantially the entire width dimension of the flange portion forwardly from its lower terminal end;
- a pair of front flanges each being attached to and extending along the inward-outward direction of the step platform being located respectively at the right and left end of the step platform and presenting an inner edge substantially parallel to the front channel wall.
A stepladder platform for attachment to a stepladder of the type having a step formed of a channel cross-section member supported at left and right ends by stiles with the step channel having a top channel wall, a rear channel wall and a front channel wall an which is open at the bottom comprising
- a stepping platform adapted to be placed upon and supported by the top channel wall, the stepping platform extending laterally forward and rearward of the forward and rearward edges of the top channel wall to provide a platform of sufficient lateral dimension and area for the sole and heel of the feet of a person standing thereon,
- means rearward of the platform for engaging the rear channel wall to prevent forward movement of the platform and clockwise tilting of the platform
- means forward of the step channel for engaging the front channel wall to prevent rearward movement of the platform and counterclockwise tilting of the platform
- means for engaging the front channel wall to prevent counterclockwise tilting of the platform.
