Definitions

  • the present invention is concerned with a mortise lock and more particularly it is concerned with such a mortise lock fitted with multiple locking bolts, the lock being actuated in different operable positions.
  • Mortise locks are well known in the art and are typically designed to fit into an opening formed at the locking stile (an edge of a door opposite the edge that is hinged to the door frame).
  • a mortise lock generally includes one or more latches (also referred to as bolts) displaceable between an extended position in which they project beyond the edge of the door into a corresponding opening in the door frame (and/or wall or sealing/floor, in some cases) so as to latch the door closed, and a retracted position in which opening of the door is facilitated.
  • latches also referred to as bolts
  • panic doors which are designed so as to quickly be opened, from the inside, at different emergency situations no matter if the door is locked or not, typically by simply actuating a door handle or bar. This requirement is to enable fast escape from an enclosure (building and the like) in case of emergency.
  • mortise locks A large diversity of mortise locks are known in the art, designed to provide different operable situations of the locking mechanism. Examples of mortise locks are disclosed in US Patents Nos. 4,154,070 and 5,678,870 and in WO 99/61734 and WO 2004/059114.

  • unbolting of the door may be selectively performed by at least one of the cylinder arrangement and the inside handle.
  • said at least one extension rod may minimally project from said outer casing, and in said second, extended position it may maximally project from said outer casing.
  • the lever plate may be articulated to said extension rod such, that retraction of the extension rod by said lever plate may entail activation of the retraction member, which may in turn entail retraction of the bolting assembly.
  • said retraction member may be in the form of a cam plate. According to another design, said retraction member may be in the form of a cam wheel.
  • the bolting assembly may comprise at least one bolt, and said outer casing may comprise a side style through which said at least one bolt is adapted to project in said first, bolted position of the bolting assembly.

  • Said lock may further comprise a latching mechanism articulated to said locking mechanism, said latching mechanism comprising a latch and a latch retractor, and adapted to assume a first, latched position in which said latch protrudes from said outer casing and a second, unlatched position in which said latch does not protrude from said outer casing.
  • each of said inside nut plate, outside nut plate and said cylinder arrangement may be articulated to said latch retractor, such that unlatching of the latching mechanism is performed by at least one of the following: i. the inside handle; ii. the outside handle; and iii. the cylinder arrangement.

  • the outside plate 506B is formed with side walls thus constituting a casing for the locking, whilst the inside face 506A serves as a cover securely attachable to the outside case 506B by means of bolts 508, as seen in Fig. 5.
  • the lock in accordance with the illustrated embodiment comprises a locking mechanism generally designated 600 which in the particular embodiment has a square receptacle 512 for receiving a corresponding square spindle 50 of an inside door handle 46

  • a face bolt 526 is also slidingly displaceable through the front plate 522 between a retracted position and a projecting position.
  • the mortise lock 500 further comprises three secondary bolts namely a top bolt 528T, a bottom bolt 528B and a rear bolt designated at 528R. It is noticed that the locking latch 524 and the face bolt 526 are displaceable upon parallel axes being substantially horizontal and similarly the rear secondary bolt 528R is displaceable upon an axis parallel to said horizontal axis. According to a different embodiment (not shown) the rear bolt fixedly projects through the rear of the door. However, the secondary bolts 528T and 528B are displaceable upon a coaxially extending axis being substantially perpendicular to said first axis. The rear and bottom bolts 528B and 528R are restricted for axial displacement by means of grooves 537B and 528R formed therein, and adapted to slidingly receive pins 563 formed in the cover 506A.
  • the secondary bolts 528T, 528B and 528R are fitted for articulation via extension rods 82T, 82B and 94 (shown Fig. 4) to corresponding auxiliary locks (not shown) respectively, for locking engagement at the locking style of a door and a hinged style of a door, respectively.
  • the secondary bolts merely activate locking rods projecting into the sashes.
  • the locking latch 524 and the face bolt 526 extend substantially symmetrically about the longitudinal axis of the front plate 522 whereby the lock is easily fitted within a "left side door” or a "right side door”.
  • a geared locking wheel 532 is pivotally secured to the casing at 534 wherein each of the secondary bolts is formed at its proximal end with a pivot arm 536T, 536R and 536B, respectively, said pivot arms being pivotally secured at a proximal end thereof to the locking wheel 532 (by pins 535T, 535B and 535R) received within grooves 533T, 533B and 533R respectively.
  • pivot arms 536T and 536B are pivoted to the locking wheel 532 about a line 531 extending through the center 534 of the locking wheel 532. It is also noticed that whilst the pivot arms 536T and 536B extend above the locking wheel 532, the pivot arm 536R extends below the locking wheel 532 with a distal end (at 535R) of the pivot arm 536R pivoted to the locking wheel 532 at a point generating a line with center pin 534 adapted to transverse the axis 531 at a substantially perpendicular relation.
  • the locking wheel 532 is engaged by a bolt cam 540, attached to a hole 533C of the locking wheel 532 by a pin 543, whereby axial displacement of the bolt cam 540 entails corresponding angular displacement of the locking wheel 532, the purpose of which will become apparent thereafter.
  • the bolt cam 540 is such that at an assembled position of the lock, in the presence of a cylinder lock, the bolt cam 540 is engaged with a corresponding latch 520 of the cylinder lock 502 (Figs. 9 to 11), whereby rotation of the cylinder lock entails an axial movement of the bolt cam 540, and corresponding angular movement of the locking wheel 532, as will become apparent hereinafter.
  • the bolt cam 540 is capable of displacing only along an axis parallel to said first axis (substantially horizontal) owing to a pin 574 (shown Figs. 9A and 9B) fixed to the bolt cam 540 and received within a corresponding groove 576 of the casing.
  • the bolt cam 540 is formed with a recess 541 at a bottom portion thereof, having a left cam shoulder 542 and a right cam shoulder 544.
  • a tooth 546 is formed, dividing the recess into two sub-recesses 541a and 541b.
  • Each of the sub recesses 541a and 541b are adapted to receive the latch 520 during corresponding rotation of the cylinder.
  • the bolt cam 540 is further formed at its top side with three consecutive recesses 549a to 549c, disposed along the axial dimension of the bolt cam 540, adapted to receive a pin therein.

L'agencement de cylindres est associé à l'ensemble de boulonnage (526) et au mécanisme de verrouillage et il est conçu pour actionner l'ensemble de boulonnage pour que celui-ci adopte une position déboulonnée ou une position boulonnée ; le mécanisme de verrouillage comprend une butée conçue pour adopter une position déverrouillée correspondant à la position déboulonnée de l'ensemble de boulonnage ou une position verrouillée correspondant à la position boulonnée de l'ensemble de boulonnage et conçue pour empêcher, en position verrouillée, la rétraction de l'ensemble de boulonnage dans sa position déboulonnée ; ladite tige d'extension au moins est articulée au mécanisme de verrouillage de sorte à adopter une position rétractée correspondant à la position déboulonnée de l'ensemble de boulonnage ou une position allongée correspondant à la position boulonnée de l'ensemble de boulonnage ; l'agencement écrou fendu comprend une plaque écrou intérieure associée à un écrou de poignée intérieur (512) et une plaque écrou extérieure associée à un écrou de poignée extérieur, la plaque écrou intérieure étant associée à ladite tige d'extension au moins et à la butée de sorte que le déplacement de la plaque écrou intérieure entraîne le déplacement simultané de la butée de la position verrouillée à la position déverrouillée et le déplacement de la tige d'extension de la position allongée à la position rétractée.
