Abstract
An access door assembly is for a floor structure. The access door assembly includes a door frame coupled to the floor structure and defining an opening aligned with a staircase, and an access door within the opening and having first and second longitudinal sides. The first longitudinal side defines a first opposing bevelled surface, and the floor structure adjacent the opening defines a second opposing bevelled surface. The access door assembly also includes an arm coupled to the access door and configured to pivot the access door between an open state and a closed state. The first and second opposing bevelled surfaces are aligned and abutting in the closed state, and are in spaced apart relation in the open state.
Claims20
An access door assembly comprising:
- a floor structure;
- a staircase below the floor structure;
- a door frame coupled to the floor structure and comprising first and second longitudinal supports defining an opening aligned with the staircase;
- an access door within the opening and comprising first and second longitudinal sides, the first longitudinal side defining a first opposing bevelled surface, the floor structure adjacent the opening defining a second opposing bevelled surface;
- and
- at least one arm coupled to the access door and configured to pivot the access door between an open state and a closed state, the access door pivoting on the first longitudinal support without a hinge, the first and second opposing bevelled surfaces being aligned and abutting in the closed state, and being in spaced apart relation in the open state, an uppermost surface of the access door and an uppermost surface of the floor structure being flush in the closed state.
An access door assembly comprising:
- a floor structure;
- a staircase below the floor structure;
- a door frame coupled to the floor structure and defining an opening aligned with the staircase, the door frame comprising first and second longitudinal supports;
- an access door within the opening and comprising first and second longitudinal sides, the first longitudinal side defining a first opposing bevelled surface, the floor structure adjacent the opening defining a second opposing bevelled surface;
- and
- at least one arm coupled between the access door and a building wall extending from a lower level, the first longitudinal support comprising a rounded uppermost portion, the at least one arm configured to pivot the access door upon the rounded uppermost portion of the first longitudinal support without a hinge and between an open state and a closed state, the first and second opposing bevelled surfaces being aligned and abutting in the closed state, and being in spaced apart relation in the open state, an uppermost surface of the access door and an uppermost surface of the floor structure being flush in the closed state.
A method for making an access door assembly for a floor structure, the method comprising:
- coupling a door frame to the floor structure and defining an opening aligned with a staircase below the floor structure, the door frame comprising first and second longitudinal supports;
- positioning an access door within the opening and comprising first and second longitudinal sides, the first longitudinal side defining a first opposing bevelled surface, the floor structure adjacent the opening defining a second opposing bevelled surface;
- and
- coupling at least one arm to the access door and configured to pivot the access door between an open state and a closed state, the access door pivoting on the first longitudinal support without a hinge, the first and second opposing bevelled surfaces being aligned and abutting in the closed state, and being in spaced apart relation in the open state, an uppermost surface of the access door and an uppermost surface of the floor structure being flush in the closed state.
