Lock for saloon-type lavatory door

Abstract

A lock assembly that includes a blocking member and a linkage assembly having a triangle member assembly and a bar member. The first corner of the triangle member assembly is pivotably attached to a first end of the bar member and a second end of the bar member is pivotably attached to the blocking member. The first leg of the triangle member assembly extends between the first and second corners, the second leg extends between the second and third corners and the third leg extends between the first and third corners. The lock assembly also includes a handle associated with the third corner of the triangle member assembly. Movement of the handle along a curved path from a start position to a finish position moves the blocking member between a first position and a second position. A first distance is defined between the handle and the blocking member when the blocking member is in the first position and a greater second distance is defined when the blocking member is in the second position.

AI Technical Summary

Benefits of technology

The door assembly described in this patent has several subsystems, including a hinge with an 180-degree rotation mechanism, a lock and gap seal mechanism, and door panels. The hinge allows for easy passage through the aisle in case of emergency, and the use of synthetic polymer fabrics ensures the door panel doesn't sag without losing its strength. The hinge requires a certain radius on both sides to function properly. Magnets can be used to bring the door back to center after being opened. The handle is made of aluminum to prevent the user's clothing or bags from getting caught in it. Overall, this door assembly provides better safety and ease of use for users.
