Abstract
An elevator door enforcer may be used to enhance the safety of an elevator landing door. The device includes a pin, and a mechanical structure that affixes the pin securely to the elevator landing door. The pin is a protruding structure that may be positioned so that a portion of the pin protrudes from the affixation point, downwards past the bottom of the elevator landing door, and into a sill groove when the elevator door enforcer is in use.
Claims20
An elevator door enforcer, comprising:
- a block defining a pin channel;
- a pin that is insertable into the pin channel;
- a pin retainer that engages with the pin to retain a position of the pin within the pin channel wherein a portion of the pin protrudes from the pin channel;
- and
- an attachment interface extending from the block and including an interface surface for contacting a leading or back edge of an elevator landing door panel.
A landing door panel to be translationally installed over a sill groove, the landing door panel comprising:
- a set of walls comprising a first face parallel to a second face, a leading edge parallel to a back edge, and a top edge, parallel to a bottom edge, wherein the first face is orthogonal to the leading edge and the top edge, and wherein the leading edge is orthogonal to the top edge;
- an elevator door enforcer situated proximate the bottom edge and abutting at least one of the leading edge and the back edge, the elevator door enforcer including:
- a downward-protruding portion that protrudes past the bottom edge of the landing door panel such that, when the landing door panel is installed over the sill groove, the downward-protruding portion extends into the sill groove to prevent displacement of the bottom edge of the landing door panel in a direction perpendicular to the sill groove by more than a width of the sill groove.
A method for installing an elevator door enforcer on an elevator door panel, wherein the elevator door enforcer includes a block defining a pin channel and a pin that is insertable into the pin channel, the method comprising:
- aligning the block of the elevator door enforcer with a vertical edge of the elevator door panel;
- affixing the block to the vertical edge of the elevator door panel;
- loosening a set screw that retains an adjustable pin of the elevator door enforcer;
- adjusting a position of the adjustable pin such that the pin extends vertically past a bottom of the elevator door panel;
- and
- tightening the set screw to fix the position of the pin.
