Abstract
Provided is a platform assembly that includes a platform having a mounting channel extending downward from the bottom of the platform at a mounting side of the platform, a support arm that supports the platform and engages a ladder, and a locking mechanism attached to the mounting side of the platform. The locking mechanism is configured to cover the mounting channel while in a locked position and uncover the mounting channel while in an unlocked position. When the platform assembly is installed on the ladder and engaged with a standoff bracket installed on the ladder, the platform provides a stable and substantially level platform allowing a user to step on and off the ladder.
Claims20
A platform assembly comprising:
- a platform having a top, a bottom, a proximal end, a distal end opposite the proximal end, a mounting side, an external side opposite the mounting side, and a mounting channel extending downward from the bottom of the platform at the mounting side of the platform, the distal end being configured to engage a roof;
- a support arm having a first end configured to engage a ladder, and a second end opposite the first end;
- a support arm mount rotatably connected to the bottom of the platform at the proximal end and the external side, wherein the second end of the arm is pivotally mounted to the support arm mount,
- a standoff bracket configured to removably engage a side of the ladder above the first end of the support arm, the standoff bracket having a mounting rail that extends outward from the side of the ladder and is angled away from the ladder at an angle, the mounting rail being configured to engage and be received within the mounting channel;
- and
- a locking mechanism attached to the mounting side of the platform, wherein the locking mechanism is configured to cover the mounting channel while in a locked position, and uncover the mounting channel while in an unlocked position,
- wherein when the standoff bracket is engaged with the side of the ladder and the platform is supported by the engagement of the first end of the arm with the ladder, the engagement of the mounting channel with the mounting rail, and the engagement of the distal end with the roof, and upon the engagement of the mounting channel with the mounting rail, the platform aligns at the angle of the mounting rail and is configured to engage the roof to support a user moving between the ladder and the roof.

A platform assembly comprising:
- a platform having a top, a bottom, a proximal end, a distal end opposite the proximal end, a mounting side, an external side opposite the mounting side, and a mounting channel extending downward from the bottom of the platform at the mounting side of the platform, the distal end being configured to engage a roof;
- a support arm having a first end configured to engage a ladder, and a second end opposite the first end;
- a support arm mount rotatably connected to the bottom of the platform at the proximal end and the external side, wherein the second end of the arm is pivotally mounted to the support arm mount;
- and
- a restraining strap with a first end connected to the bottom of the platform and a second end configured to wrap around the ladder and tighten to prevent the platform assembly from sliding away from or disengaging the ladder,
- wherein when the platform is engaged with the ladder, the platform extends outward from a side of the ladder and is angled away from the ladder and toward the roof to engage the roof, the platform being configured to support a user moving between the ladder and the roof.

A platform assembly for engaging a side of a ladder, the platform assembly comprising:
- a platform having a top, a bottom, a proximal end, a distal end opposite the proximal end, and a mounting channel extending downward from the bottom of the platform at the proximal end of the platform, the distal end being configured to engage a roof;
- a support arm having a first end configured to engage a side of a ladder, and a second end opposite the first end, wherein the second end is rotatably and pivotally mounted to the bottom of the platform;
- and
- a standoff bracket configured to removably engage the side of the ladder above the first end of the support arm, the standoff bracket having a mounting rail configured to be received within the mounting channel,
- wherein the platform extends outward from the side of the ladder and angled away from the ladder and is configured to support a user moving between the ladder and the roof when the platform is supported at the proximal end by the engagement of the first end of the support arm with the side of the ladder and by the engagement of the mounting channel with the mounting rail, and the platform is supported at the distal end by engagement of the distal end with the roof.
