Definitions

  • the present invention broadly concerns latch and release mechanisms for doors.
  • the present invention particularly concerns latch and release mechanisms for doors, including glass panel doors and the like.
  • This invention specifically concerns an emergency release or break-away latch assembly for automatic sliding doors, but the invention also may apply to swinging doors.
  • closure structures have been associated with the entryways of dwellings and buildings throughout history. These closure structures range from simple draped fabrics to a standard hinged door and to more elaborate mechanical devices that are used in commercial applications. Many simple closure structures do not include latch and/or locking capabilities. On the other hand, more elaborate structures can include a variety of components which secure the door and position and control access to the entryway.
  • Automatic doors In modern commercial buildings, automatic doors have become commonplace. Automatic doors are typically electronically operated so that, as a person approaches, the door moves from a closed position to an open position. Automatic doors typically respond to an input signal that senses the presence of a person.
  • a pressure pad was placed in front of the door on the walking surface. When a person steps on the pressure pad, the weight of the person closes a switch that sends a signal to the door operating mechanism to cause that mechanism to open the door.
  • motion and proximity to detectors have been used to determine the presence of a person at the entryway. When a person enters the sensor zone, a signal is produced that causes the door operating mechanism to open the door.
  • Automated sliding doors are typically constructed as a unit wherein a slide panel is slightly offset from but is parallel to a fixed panel. The slide panel slides relative to the fixed panel to create a doorway opening for ingress and egress. Often, a pair of such units are placed in end to end relation so that the slide panels abut one another in a common plane. In such configurations, the presence of an operative signal causes both slide panels to slide away from one another presenting a doublewide entryway opening for ingress and egress.
  • the closing force of a traditional automated swinging door can be manually overcome, it is more difficult to overcome the closing force of an automatic sliding door. This could potentially cause a problem should power fail to be supplied to an automated door. This can occur in situations such as power outages, fires and the like. Since ii is desirable to permit persons located within the building to exit the building under such circumstances, it is known to provide automatic sliding doors with a breakaway capability.
  • the sliding door in addition to its sliding capability, the sliding door is mounted on a hinge or pivot that defines a vertically oriented axis for swinging motion of the sliding door.
  • a latch mechanism is located along an opposite edge of the door with this latch mechanism normally retaining the sliding door in its normally closed position.
  • a manually actuable release mechanism is then associated with the door such that, upon activation, the release mechanism operates the latch mechanism to release the sliding door so that it may pivot along the vertical axis in a manner of a normal door. This feature is called a "break-away capability".
  • Another object of the present invention is to provide a new and useful emergency release assembly adapted for use in a sliding door as well as a sliding door incorporating such an emergency release assembly.
  • Yet another object of the present invention is to provide an emergency release mechanism and sliding door incorporating the same where the mechanism normally fits entirely within the recess of a muntin yet which may be manually tripped so that it may be expanded for ease of installation, maintenance and repair.
  • Still another object of the present invention is to provide an emergency release assembly and sliding door incorporating the same that is simple and reliable in construction and operation.
  • an emergency release assembly is disclosed that is adapted for use with a door that is supported by a framework when in a normally closed configuration yet that is moveable in an emergency condition between the normally closed configuration and an emergency open configuration.
  • This emergency release assembly is especially incorporated, according to the present invention, in a sliding door system with break-away capability wherein the sliding door system includes a fixed panel oriented in the first plane a guide structure extending parallel to the fixed plane and a carriage piece disposed in the guide structure for sliding movement relative to the fixed panel.
  • a sliding door is secured to the carriage piece so that the door slidingly moves with the carriage piece between a slideable closed position relative to the fixed panel and a slideable open position relative to the fixed panel and wherein the sliding door is also pivotally mounted with respect to the carriage piece so that it may pivot between a normally closed configuration and an emergency open configuration.
  • the release assembly whether for a swinging door or a sliding door, includes a latch mechanism that is operative in the first state to retain the door in the normally closed position and is actuable to a second state that allows the door to be moved to an open position.
  • the release assembly also includes a release mechanism that is operative to advance the latch mechanism from the first state to the second state.
  • the release mechanism includes a reciprocating control member coupled to the latch mechanism and supported by the door for reciprocal sliding movement.
  • a manually actuable push bar is provided and at least one link member interconnects the push bar and the reciprocating member in a manner such that the push bar may be moved between a fully extended position and a depressed position through an intermediate extended position.
  • a catch member is provided that operates in a retained state to limit movement of the push bar between the intermediate extended position and the depressed position yet the catch member is releasable to an access state when the push bar can move from the intermediate position to the fully extended position.
  • This release mechanism can be used as a primary latch and release assembly for a door as an emergency or "one-way" release.
  • the link member is defined by a scissors unit formed by first and second legs that are pivotally interconnected to one another. Specifically, a pair of link members interconnect the push bar and the reciprocating members with these link members being positioned and spaced apart in relation to one another. In each case, both link members are then defined by a scissors unit.
  • the first leg of each scissor unit has a proximal end secured to the reciprocating member and a distal end opposite the proximal end.
  • a second leg then has a proximal end secured relative to the door and a distal end secured to a medial portion of the first leg.
  • a mounting plate is supported on the distal end of the first leg and the push bar may be secured to the mounting plate.
  • the latch mechanism includes a reciprocating latch actuator rod
  • the release mechanism includes a rotatable drive element and a crank arm.
  • the crank arm has a first crank arm end that is secured to the reciprocating member and a second crank arm end secured to the drive element such that reciprocation of the reciprocating member acts to reciprocally rotate the drive element
  • the actuator rod has a first rod end secured to the drive element whereby reciprocal rotation of the drive element acts to reciprocate the actuator rod.
  • the first crank arm end moreover may be slideably secured to the reciprocating member such that the drive element is not rotated when the push bar moves from the intermediate extended position to the fully extended position.
  • the push bar is biased toward the fully extended position. This is accomplished by means of a return spring mounted on the legs of the scissor unit (s) which biases them into an extended position.
  • the release mechanism includes a base member that is adapted to be supported by the door, such as by slide channels formed within the muntin recess.
  • the link member or members interconnect the base member and the reciprocating member for reciprocal motion of the reciprocating member relative to the base member.
  • the catch member is defined by a lever that is pivotally secured to the base member with the lever including a lever arm section that interacts with the scissor unit to limit movement thereof so that is may not move from the intermediate extended position to the fully extended position when in the retained state.
  • This lever is pivotable out of the retained state so that the scissor assembly may expand to the fully extended position.
  • the push bar then has an access opening whereby the lever may be manually pivoted out of the retained state.
  • the release mechanism is adapted to be disposed in the muntin recess of a sliding door so that, when the push bar is in the intermediate extended position and in the depressed position, it is captured completely within the interior of the recess so that the push bar does not protrude outwardly therefrom.
  • the catch member retains the push bar within the muntin recess but, when moved to the access state, allows the push bar to extend out of the recess when in the fully extended position thereby to allow access for installation and maintenance.
  • the present invention also is directed to a sliding door incorporating a latch mechanism and a release mechanism, as described above.
  • the sliding door includes a framework that has a muntin.
  • a latch mechanism is disposed in the framework and operates in the first state to retain the sliding door in the normally closed configuration yet which is actuable to a second state that allows the sliding door to be moved to the emergency open configuration.
  • a release mechanism is then disposed in the muntin and operates to advance the latch mechanism from the first state to the second state.
  • the release mechanism includes a control member coupled to the latch mechanism and supported for reciprocal sliding movement, a push bar at least one link member interconnecting the push bar and the control member and a catch member, all as described above.
