Abstract:

A door positioning system is provided. The system includes a first member and a second member. The first member is attached to an exterior door at a first end of the first member and to an anchor location at a second end of the first member opposite the first end. The first member includes a locking region. The second member is configured to engage the locking region of the first member if the exterior door is opened a first threshold amount. The second member and locking region are configured to hold the exterior door in an open position if the second member is engaged with the locking region. The second member and locking region are configured to disengage if the exterior door is opened a second threshold amount beyond the first threshold amount. The exterior door is able to close with the force of the door closer if the second member is disengaged from the locking region.

Abstract:

A pull and release latch including a releasable lock featuring stress preventers and a limit stop. The limit stop prevents the releasable lock from cantilevering too much to the point of breaking or stressing the releasable lock. A unique design allows a male component and a female component to be easily engaged while at the same time the pulling force to release the lock gives the same motion to separate the two components in a direction perpendicular to a cantilever axis.
