This invention relates generally to locking of hinged panels, such as doors or windows or the like, and more particularly to a locking arrangement, and a method for operating a locking arrangement, for securing single or multiple hinged panels to a frame, other panels, or a jamb, using one or more lock-points.
Through the centuries, many devices and methods have been used for locking, or otherwise securing, hinged panels, such as single or double swinging doors, windows, or shutters in a frame, or jamb, to preclude entry into, or egress from, one space from another, to thereby provide security and/or protection from the elements. A number of factors must be taken into consideration in the design of such locking arrangements and their manner of operation.
A primary consideration is that the locking arrangement must, indeed, provide adequate security against forcible entry, when the locking arrangement is deployed. Through the years, it has thus become known to provide locking arrangements having more than one lock-point, in the form of dead-bolts, shoot-bolts, locking tongues, and/or hook-type latches, and the like, for engaging the jamb or frame surrounding the hinged panel, or for engaging an adjacent panel in a French door arrangement. It has also become common practice to include some form of latch mechanism, in the locking arrangement, for holding a door, or doors, in a closed but unlocked state, to provide protection from the elements, or entry of insects, or other vermin, into a space protected by the closed panel.
Another primary consideration, in the design of locking arrangements, is that they be conveniently and intuitively operable. For example, it is desirable that a locking arrangement be operable through manipulation of a minimal number of input elements, such as handles, thumb-turns, or keyed lock cylinders. This is particularly true with regard to locking arrangements having multiple lock-points in single or double-hinged panel arrangements. In a locking arrangement having multiple lock-points, for example, it is desirable that operation of all lock-points can be accomplished through manipulation of one, or at most two, input elements, given the fact that a person operating the locking arrangement has only two hands with which to simultaneously operate various input elements such as handles and thumb-turns. Intuitive operation of a minimum number of input elements can be especially critical in emergency situations, where a person, inside of a space secured by the locking arrangement, may need to quickly exit the space in the dark, or in reduced visibility situations caused by smoke in the case of a fire within the space, for example.
Applications of locking arrangements in double panel installations, such as French doors, require additional design considerations. In such installations, one of the hinged panels is typically a so-called active panel, through which primary ingress and egress takes place, and the other hinged panel is a so-called inactive panel which generally is secured to the jamb or frame surrounding the inactive panel in a manner allowing the inactive panel to be opened only when it is desirable to have a bigger opening than is provided by the active panel alone. In prior double door arrangements, for example, locking arrangements in inactive panels have sometimes included separately operable shoot-bolt-type latches located at the top and/or bottom of the inactive panel which can be individually actuated to engage corresponding holes or anchor points in the door jamb and the floor adjacent the inactive panel. Alternatively, such shoot-bolt-type locking arrangements, in an inactive panel, have been connected to a centrally operable actuation handle of the locking arrangement in the inactive panel.
Where double panel arrangements are utilized, it is desirable to provide some means for precluding improper operation of the locking arrangements in both the inactive and active panels. For example, it is desirable to preclude operation of any lock-points in the locking arrangement of an active panel which engages an inactive panel, without the lock-points of the inactive panel having been previously engaged with the frame. If a dead-bolt in the active panel is engaged with an inactive panel that has not been previously secured to the jamb, force applied to the outside of the panels may be capable of causing the panels to open, possibly with damage to the locking arrangement and/or one or both of the panels, even though it appears that the doors are securely locked. By configuring the locking arrangement such that normal operation of the input elements (such has handles and thumb-turns or key cylinders) in the active panel is inhibited until the inactive panel is securely locked in place, a person operating the door is alerted to the fact that the inactive panel is not properly secured.
It is also desirable that lock-points and latch components of the locking arrangement which extend beyond the edges of the panels in a locked state, be precluded from movement to that extended locked state, prior to the panels being properly positioned in a closed position, within the frame and with respect to one another, in order to preclude inadvertent contact of the latches and/or lock-points with the frame or the panels in a manner that would cause damage to the locking arrangement, the panels, the frame, or trim around the panel opening.
Another consideration, applicable to double-panel applications of locking arrangements, is that the operation of the input elements for controlling the locking arrangement in both the active and inactive panels be such that a person unfamiliar with the locking arrangement will intuitively be able to tell which one of the double panels is the active panel, particularly in an emergency exit situation, when both panels are locked. This is so because, typically, the active panel must be opened before the inactive panel can be opened in most common double-panel installations. Where the input controls on the active and inactive doors have a similar appearance, or feel, a person attempting to escape through the panels in an emergency situation might otherwise waste valuable time in a vain attempt to open the inactive panel rather than the active panel.
Another highly desirable feature would be providing the capability to lock the locking arrangement from outside of the panel or panels without using a key.
Prior locking arrangements and methods have not been entirely satisfactory in meeting the requirements and desired functionality discussed above, or have been found to be inadequate in other respects.
It is desirable, therefore, to provide an improved locking arrangement, and method, for operating a locking arrangement in hinged single-panel or multiple-panel installations. It is also desirable that such an improved locking arrangement and method be applicable in embodiments having single, and/or multiple lock-points. It is further desirable that such an improved locking arrangement and method be usable in forms that include a latch arrangement.
The invention provides an improved panel locking arrangement, and method for operating a locking arrangement, through use of a lock-point arming input element that is connected directly to a handle-operated control element of the locking arrangement, rather than being connected directly to a lock-point of the panel locking arrangement. The lock-point is movable only through operation of the handle-operated control element.
In one form of the invention, the lock point arming element is selectively moveable between an armed and a disarmed position thereof, and is configured and connected to the handle-operated control element in such a manner that the handle-operated control element may be used to move the lock-point to the locked position thereof only when the lock-point arming input element is in the armed position thereof.
In some forms of the invention, the lock-point arming input element may include or take the form of a thumb-turn and/or keyed cylinder, and the handle-operated control element may include or be adapted for attachment thereto of a door handle. In stark contrast to prior locking arrangements, however, such a thumb-turn or key-operated cylinder is not operatively connected directly to the deadbolt or other lock point. In the present invention, one or more lock-points are moveable from the unlocked to the locked position thereof only by first turning the thumb-turn or key-operated cylinder to the armed position thereof, and then using the door handle attached to the handle-operated control element for moving the one or more lock-points from the unlocked to the locked positions thereof.
In one form of the invention, the lock-point arming input element is selectively moveable between an armed and a disarmed position thereof, and is configured and connected to the handle-operated control element in such a manner that the handle-operated control element may only be used to move the lock-point to the locked position thereof when the lock-point arming input element is in the disarmed position thereof.
In various forms of the invention, a locking arrangement and method are provided, for use in hinged single-panel or multiple-panel installations. A locking arrangement and/or method, according to the invention, may be applicable in forms having single, and/or multiple lock-points. Some forms of a locking arrangement and/or method, according to the invention, may include a latching arrangement.
Terms such as “door” and “panel,” as used herein, are contemplated to be generally interchangeable, and to be inclusive rather than limiting, with those having skill in the art readily understanding that the invention may be practiced with a wide variety of hinge-mounted, panel-like elements, including: doors, windows, shutters, and the like.
In one form of the invention, a door locking arrangement includes a door locking apparatus for moving at least one lock-point between a locked and an unlocked position thereof. The lock-point apparatus includes a handle-actuated control element, a lock-point actuation apparatus adapted for attachment thereto of the at least one lock-point, and a lock-point arming input element that is selectively moveable between an armed and a disarmed position thereof. The handle-operated control element is selectively moveable between first and second angular positions thereof, and an intermediate angular position thereof disposed between the first and second angular positions. The door locking apparatus is configured such that moving the at least one lock-point from the unlocked to the locked position thereof is accomplished only by, first moving the lock-point arming input element from the disarmed to the armed position thereof, and then moving the handle-actuated control element from the intermediate position thereof to the second position thereof.
A door locking apparatus, according to the invention, may include an inside handle-actuated control element, an outside handle-operated control element, a lock-point actuation apparatus having at least one lock-point that is moveable between a locked and an unlocked position thereof, and a lock-point arming input element that is selectively moveable between an armed and a disarmed position thereof. The handle-operated control elements are selectively moveable between respective first and second angular positions thereof, and respective intermediate angular positions thereof disposed between the first and second angular positions. The door locking apparatus is configured such that moving the at least one lock-point from the unlocked to the locked position thereof is accomplished only by first moving the lock-point arming input element from the disarmed to the armed position thereof, and then moving one of the handle-actuated control elements from the intermediate position to the second position thereof.
A door locking apparatus, according to the invention, may further include one or more of the group consisting substantially of: an inside handle operatively connected to the inside handle-actuated control element; an outside handle operatively connected to the outside handle-actuated control element; a thumb-turn operatively connected to the lock-point arming input element; a lock cylinder operatively connected to the lock-point arming input element; multiple lock-points; connecting and mounting elements for operatively connecting multiple lock-points to one another; and decorative hardware.
In some forms of the invention, a door locking apparatus may be configured such that, moving an inside handle-actuated control element from the intermediate position thereof to the first angular position thereof retracts the at least one lock-point and moves the lock-point arming input element from the armed to the disarmed position thereof.
In some forms of the invention, a door locking apparatus may be configured such that, once the lock-point arming device has been moved to the armed position, moving the outside handle-actuated control element from the intermediate to the second angular position thereof extends the at least one lock point. In this manner, the door may be locked from the outside without a key by sequentially moving the lock-point arming input element to the armed position while the door is standing open, closing the door, and raising the outside handle-actuated control element to the second position thereof.
A door locking apparatus, according to the invention, may be configured such that an outside handle-actuated control element is blocked against movement from the intermediate position thereof to the first position thereof when the lock-point arming control element is in the armed position. The door locking apparatus may also be configured such that, moving the inside handle-actuated input element from the intermediate position thereof to the first angular position thereof retracts the at least one lock-point and moves the lock-point arming input element from the armed to the disarmed position thereof.
In some forms of a door locking arrangement, according to the invention, having inside and outside handle-actuated control elements, the door locking arrangement may be selectively reconfigured in such a manner that the inside handle-actuated control element becomes an outside handle-actuated control element, and the outside handle-actuated control element becomes an inside handle-actuated control element.
Some forms of a locking arrangement, according to the invention, may further include a latch that is selectively moveable between a fully extended latch position thereof and a retracted position thereof through movement of either of an inside or an outside handle-actuated input element from the intermediate to the first position thereof, when the lock-point arming input element is in the disarmed position thereof, and through movement of only the inside handle-actuated input element from the intermediate to the first position thereof, when the lock-point arming input element is in the armed position thereof. A door locking apparatus, according to the invention, may be further configured such that movement of the inside and outside handle-actuated input elements from the intermediate to the second positions thereof can only move the at least one lock lock-point from the unlocked to the locked position there of when the latch is substantially in a fully extended latched position thereof.
In a door locking arrangement, according to the invention, a door locking apparatus may be either an active door locking apparatus, or an inactive door locking apparatus, and in some forms of the invention, a door locking arrangement may include both an active door locking apparatus and an inactive door locking apparatus.
An inactive door locking apparatus, according to the invention, may include one or more of the elements of a group consisting substantially of: an inside handle operatively connected to the inactive door handle-actuated control element; an outside handle operatively connected to the inactive door handle-actuated control element; a thumb-turn operatively connected to the inactive door lock-point arming input element; multiple inactive door lock-points; connecting and mounting elements for operatively connecting multiple inactive door lock-points to one another; and decorative hardware.
In a door locking arrangement, according to the invention, having both an active and an inactive door locking apparatus, the inactive door apparatus may include a latch receptacle and a latch blocker. The latch receptacle is configured for receiving therein the latch of the active door locking apparatus, and the latch blocker is moveably disposed in the latch receptacle. The latch blocker is operatively connected to the inactive door lock-point in such a manner that the latch of the active door locking apparatus is precluded from extending substantially fully into the latch receptacle when the inactive door lock-point is not in the locked position thereof. Where the active door locking apparatus includes multiple lock-points, the multiple active door lock-points may all be blocked against movement to their respective lock positions when the inactive door lock-point is not in the locked position thereof.
An inactive door locking apparatus, according to the invention, may have at least one inactive door lock-point, an inactive door lock-point actuation apparatus, a latch receptacle configured for receiving therein a latch of an active door locking apparatus, according to the invention, and a latch blocker moveably disposed in the latch receptacle. The at least one inactive door lock-point is operatively connected to the inactive door lock-point actuation arrangement for selectively moving the at least one inactive door lock-point between the locked and unlocked positions thereof. The latch blocker is operatively connected to the inactive door lock-point in such a manner that the latch of the active door locking apparatus is precluded from extending substantially fully into the latch receptacle when the inactive door lock-point is not in the locked position thereof.
In a door locking arrangement having both an active and an inactive door locking apparatus, according to the invention, the inactive door locking apparatus may include at least one inactive door lock-point, an inactive door lock-point actuation apparatus, an active door latch receptacle configured for receiving therein a latch of the active door locking apparatus, and an active door latch blocker moveably disposed in the latch receptacle. The at least one inactive door lock-point is operatively connected to the inactive door lock-point actuation apparatus for selectively moving the at least one inactive door lock-point between the locked and an unlocked position thereof. The active door latch blocker is operatively configured and connected to the inactive door lock-point actuation apparatus in such a manner that the lock-point of the inactive door locking apparatus is precluded from movement from the locked to the unlocked position thereof when the active door latch is in the latched position thereof. Where an inactive door locking apparatus, according to the invention, includes multiple door lock-points, all of the multiple inactive door lock-points may be blocked against movement from their respective locked positions to their respective unlocked positions, when the active door latch is in the latched position thereof.
An inactive door locking apparatus, according to the invention, may further include a handle-controlled actuation apparatus, selectively moveable between a first position thereof, a second position thereof, and an intermediate position thereof disposed between the first and second positions of the handle-controlled actuation apparatus, and an inactive door lock-point arming arrangement, including an inactive door lock-point arming input element that is moveable from an armed to a disarmed position thereof. The handle-controlled actuation apparatus and inactive door lock-point arming input device are configured and operatively connected such that, to move the inactive door lock-point from the unlocked to the locked position thereof, the handle-actuated input element is moved from the intermediate position to the second position thereof.
An inactive door handle-controlled actuation apparatus and inactive door lock-point arming device, according to the invention, may be further configured and operatively connected such that movement of the inactive door lock-point to the locked position thereof urges the inactive door lock-point arming input element to move to the armed position thereof and secure the inactive door lock-point in the locked position thereof. The inactive door handle-controlled actuation apparatus and inactive door lock-point arming arrangement may also be configured and operatively connected such that, with the inactive door lock-point in the locked position, moving the inactive door lock-point arming input element to the disarmed position thereof does not move the inactive door lock-point to the unlocked position thereof. The inactive door lock point arming input element may be spring-biased in such a manner that it is urged to move to the armed position thereof, such that, when the inactive door lock-point is moved to the locked position, or is in the locked position, the inactive door lock-point arming input element is biased to move toward the armed position thereof.
An inactive door locking apparatus, according to the invention, may be configured such that, to move the inactive door lock-point from the locked to the unlocked position thereof, the inactive door lock-point arming input element must be moved to, and held in, the disarmed position thereof, while the inactive door handle-controlled input element is moved to the second position thereof.
In a door locking arrangement, according to the invention, the active and inactive door locking apparatuses may be cooperatively configured, such that the inactive door handle-controlled input element is blocked against movement from the intermediate position thereof whenever a latch or a lock-point of the active door locking apparatus is disposed within a corresponding receptacle of the inactive door locking apparatus.
A door locking apparatus, according to the invention, may be a primary lock apparatus adapted for operative attachment to a door hinged to a door jamb for swinging motion about a door hinge axis, from a closed to an open position of the door, with the door defining an inside and outside surface thereof joined by oppositely disposed lock-side and hinge-side door edges, with the door having a longitudinal door length extending in a direction substantially parallel to the door hinge axis, a transverse door with extending substantially between the lock-side and hinge-side door edges, and a door thickness extending between the inside and outside surfaces of the door. The primary lock apparatus may be an active door lock apparatus, including an active door lock frame having operatively attached thereto: a lock-point actuation apparatus, including the at least one lock-point; independently operable first and second handle-operated actuation apparatuses, respectively including the first and second handle-controlled input elements; and a handle motion control apparatus, including the lock-point arming input element. The primary lock frame defines mutually orthogonally-directed longitudinal, transverse, and thickness axes of the active door lock apparatus, with the longitudinal active door lock axis extending substantially parallel to the door hinge axis and the transverse active door lock axis aligning respectively parallel to the door hinge axis and the width of the door when the active door lockset is operatively attached to the active door.
The lock-point actuation apparatus is operatively connected to the first and second handle-operable actuation apparatuses, and includes a lock-point actuation slide that is moveable along a substantially linear path in a direction substantially parallel to the longitudinal axis of the primary lock apparatus between a locked and an unlocked position of the lock-point actuation slide. The configuration and interconnection of the first and second handle-operated actuation apparatuses with the lock-point actuation apparatus is such that the lock-point actuation slide is urged to move from the locked to the unlocked positions thereof by movement of the input element of either of the first and second handle-operated input elements to the first position thereof, and such that the lock-point actuation slide is urged to move from the unlocked to the locked position thereof by movement of the input element of either of the first and the second handle-operated input elements to the second position thereof. The configuration and interconnection of the handle-motion control apparatus and the first and second handle-operated control apparatuses is also such that movement of the lock-point arming element between the armed and disarmed positions thereof controls selective movement of the input elements from the first and second handle-controlled actuation apparatuses, to thereby control movement of the lock-point actuation slide, and is yet further such that movement of the lock-point arming element between the armed and disarmed positions thereof does not move the lock-point actuation slide.
The first and second handle-controlled actuation apparatuses of a primary locking apparatus, according to the invention, may respectively take the form of first and second input hubs respectively forming the first and second handle-controlled input elements and first and second handle-motion control slides. The first and second input hubs may be rotatably mounted for independent rotation about a common input hub axis extending substantially parallel to the thickness axis.
The first handle-motion control slide is connected in gear mesh relationship with the first input hub, in such a manner that application of torque in a first direction to the first input hub urges angular motion of the first input hub in the first direction, to thereby impart linear motion in a first direction to the first handle-motion control slide and, such that application of torque in a second direction to the first input hub urges angular motion of the first input hub in the second direction, to thereby impart linear motion in a second direction to the first handle-motion control slide.
In similar fashion, the second handle-motion control slide is connected in gear mesh relationship with the second input hub in such a manner that application of torque in a first direction to the second input hub urges angular motion of the second input hub in the first direction, to thereby impart linear motion in a first direction to the second handle-motion control slide, and, such that application of torque in a second direction to the second input hub urges angular motion of the second input hub in the second direction, to thereby impart linear motion in a second direction to the second handle-motion control slide.
The first and second handle-motion control slides are both operatively connected to the lock-point actuation slide in such a manner that the lock-point actuation slide is urged to move from the locked to the unlocked position thereof by movement of the input hub of either of the first and second handle-motion control apparatuses to the first position thereof, and, such that the lock-point actuation slide is urged to move from the unlocked to the locked position thereof by movement of the input hub of either of the first and second handle-motion control apparatuses to the second position thereof.
The lock-point arming input element is operatively connected to both the first and second lock-point actuation slides in such a manner that: both the first and second lock-point actuation slides are precluded from moving to the second position thereof, when the lock-point arming input element is in the disarmed position thereof; and both the first and second lock-point actuation slides may be selectively and independently moved to the first position thereof, when the lock-point arming input element is in the disarmed position thereof.
The lock-point arming apparatus may be operatively connected to the frame, and include a lock-point arming input element in the form of an arming hub operatively attached to the frame for selective rotation about an arming hub axis extending substantially parallel to the thickness axis, for selective rotation from an armed to a disarmed angular position of the arming hub. The lock-point arming apparatus may further include: a traveling rack element, a handle-motion-control-slide stop-pivot element; a torsion spring; a pivotable gear sector element; and first and second selectively moveable handle-motion control slide pin-stops. The traveling rack element is connected in a gear mesh relationship with the arming hub, and slideably mounted in the frame for substantially linear movement between armed and disarmed linear positions of the traveling rack corresponding respectively to the armed and disarmed positions of the arming hub, in such a manner that moving the arming hub between the armed and disarmed positions of the arming hub urges a corresponding movement of the traveling rack element between the armed and disarmed positions thereof.
The stop pivot element is pivotably attached to the frame for pivotable movement between armed and disarmed angular positions thereof, and configured such that, when positioned in the disarmed position, the stop-pivot engages and precludes movement of either of the first and/or second handle-controlled slides to the respective second positions of the handle-control slides. The stop pivot element is further pivotably attached and configured such that, when positioned in the armed position thereof, the stop-pivot element disengages from, and does not preclude movement of, either of the first and/or the second handle-control slides to the respective second positions of the handle-control slides.
The traveling rack element and stop-pivot element are cooperatively configured and mounted for sliding engagement with one another, such that movement of the traveling rack element toward the disarmed position thereof urges the stop-pivot element to engage with the first and second handle-motion control slides, in such that movement of the traveling rack element toward the armed position thereof urges the stop-pivot element to disengage from the first and second handle-motion control slides.
The stop-pivot return spring is operatively connected between the frame and the stop-pivot element to provide a biasing force for urging the stop-pivot toward a position of sliding engagement with the traveling rack element.
The pivotable gear sector element is pivotably mounted to the frame and operatively connected in a gear mesh relationship to the arming hub in such a manner that movement of the arming hub to the armed position thereof moves the pivotable gear sector to an armed position thereof. The pivotable gear sector includes a stop-pin support arm adapted for removable attachment thereto of the first stop-pin, and configured for bringing the first stop-pin into alignment with a notch in one of the first and/or second handle-motion control slides, when the pivotable sector gear is in the armed position thereof, for precluding linear movement of the slide to the first position thereof. The second stop-pin is attached to the traveling rack element for operative engagement with the other of the first and/or second handle-motion control slides in such a manner that the other of the slides may move to the second position thereof without urging movement of the traveling rack element, but such that movement of the other of the slides to the first position thereof moves the traveling rack element linearly in such a manner that the gear mesh relationships between the traveling rack element and the arming hub rotates the arming hub from the armed to the disarmed positions thereof. Rotation of the arming hub simultaneously pivots the pivotable gear sector element from the armed to the disarmed positions thereof.
In some forms of the invention, the first and second stop-pins are mounted on opposite sides of the traveling rack element and gear sector arm to define the inside and outside handle actuator mechanisms.
The invention may also take the form of a method for constructing and/or operating a door locking apparatus, according to the invention. In a method for operating a door locking apparatus, according to the invention, wherein the locking apparatus includes an inside handle-actuated control element, an outside handle-operated control element, a lock-point actuation apparatus having at least one lock-point that is moveable from a locked to an unlocked position, and a lock-point arming input element that is selectively moveable between an armed and a disarmed position thereof, with the handle operated control elements being selectively moveable between first and second angular positions thereof, and intermediate angular positions thereof disposed between the first and second angular positions, a method, according to the invention, may include: moving the lock-point arming input element from the disarmed to the armed position thereof, and then moving at least one of the at least one lock-points from the unlocked to the locked position thereof by moving one of the handle-actuated control elements from the intermediate position thereof to the second position thereof. A method, according to the invention, may further include retracting the at least one lock-point and moving the lock-point arming input element from the armed to the disarmed position thereof by moving the inside handle-actuated control element from the intermediate position thereof to the first angular position thereof. A method, according to the invention, may also include, blocking the outside handle-actuated control element against movement from the intermediate position thereof to the first position thereof when the lock-point arming control element is in the armed position.

Specifically, rotation of the lock-point arming hub 172 from the disarmed to the armed position thereof causes a corresponding upward longitudinal movement of the traveling rack element 244 to an armed position thereof, within the slots 276 in the first and second side plates 220, 222. As seen in
Rotation of the arming hub 172 from the disarmed to the armed positions thereof, causes a corresponding rotation of the pivotable gear sector element 250 from its disarmed position, as shown in
When the pivotable gear sector element 250 is in its armed position, as shown in
As shown in
By virtue of the configuration and connection of the first and second stop-pins 252, 254 with mating elements within the primary active door locking apparatus 146, it will be seen that a downward movement of the inside handle 164 from the intermediate position B to the first position A thereof will withdraw the latch 158 and return the arming input hub 172 to its disarmed position, to thereby place the primary active door locking apparatus 146 back in the position previously described with respect to 14A, wherein the active door 102 may be opened from the inside simply by rotating the inside handle 164 to the first position A thereof. This aspect of the invention, therefore, provides a simple, and intuitively straightforward, method of quickly exiting from the enclosed space, by simply pressing down on the inside handle 164, without the need for also simultaneously or previously having to rotate a thumb turn or key-lock in the manner required for retracting deadbolts in prior locking arrangements. The functionality of this aspect of the invention thus makes it possible to exit the enclosed space using only one hand, while the other hand may be occupied for other purposes, such as carrying packages or a child.
With the arming input hub 172 in its armed position, and the primary active door locking apparatus 146 in the positional state shown with respect to
As further indicated in
Specifically, rotation of either of the inside or outside handles 164, 174 to the second position C thereof, causes a corresponding rotation of the respective input hub 168, 182 to a second angular position thereof, as shown in
As the lock-point actuation slide 234 moves downward, a gear mesh relationship between the lock-point actuation slide and the deadbolt actuator 235 causes the deadbolt actuator 235 to rotate about its axis 282 from an unlocked position thereof, as shown in
As further shown in
As shown in
Specifically, with the arming hub 172 in the disarmed position D, downward movement of either the inside or outside handle 164, 174 from the intermediate position B thereof to the first position thereof causes the corresponding input hub 168, 182 to rotate and drive the corresponding handle-control-motion-slide, 240 or 242, downward until the top surface of the notch on the lower end of the corresponding handle-motion-control-slide, 240 or 242, engages the protrusions 292 on one end of the drive lever 236 to move downward and impart a reverse rotation to the drive lever about its axis 290, which, in turn, causes a reversing of the motion described above with regard to
Downward movement of the inside handle 164 from its intermediate position B to its first position A, with the primary active door locking apparatus 146 is allowed, by virtue of the configuration and connection of the components as described above, when the locking apparatus 146 is in its fully locked and latched position, as indicated by dashed lines in
In addition to causing the lock-point actuation slide 234 to move from its locked to the unlocked position thereof, downward movement of the first handle-motion-control-slide 240, by virtue of a downward rotation of the inside handle 164 causes the traveling rack 244 to be pulled longitudinally downward to its disarmed position, which results in the arming hub 172, stop pivot 246 and pivotable gear sector element 250 also being returned to their disarmed positions as shown in
It will be appreciated that, by simply moving the inside handle 164 downward to its first position A, the primary active door locking apparatus 146 may be moved from its fully locked and latched state, as shown in
The exemplary embodiment of the primary active door locking apparatus 146 may also be restored from a fully locked and latched state, as shown in
From outside of the active door 102, the primary active door locking apparatus 146 can only be unlocked and unlatched from the fully-locked and latched state by first using the keyed lock cylinder 176 to rotate the input arming hub 172 to its disarmed position, which will release the outside (second) handle-motion-control-slide 242 to move downward and thereby allow downward movement of the handle 174, followed by downward movement of the outside handle 174 from its intermediate position B to the first position A thereof.
It will further be understood, by those having skill in the art, that the upper and lower ends of the lock-point actuation slide 234 are adapted for attachment respectively thereto of the upper and lower secondary lock-point drive rails 152, 154, which transfer motion of the lock-point actuation slide 234 to the upper and lower tongue lock-point apparatuses 148, 150, in such a manner that as the lock-point actuation slide 234 moves from the unlocked to the locked positions thereof, corresponding movement of the upper and lower tongue locking apparatuses 148, 150 from their unlocked to locked positions also occurs, in the exemplary embodiment of the multi-point active door locking apparatus 142.
As shown in
Operatively mounted within the frame 336 of the primary inactive door locking apparatus 184 is, a lock-point actuation arrangement, in the form of a first (upper) lock-point actuation slide 350, a second (lower) lock-point actuation slide 352, a second (lower) lock-point slide drive link 354, and a primary inactive door-locking apparatus drive lever 355. Also operatively mounted within the frame 336 of the primary inactive door locking apparatus 184 are, the handle-actuated input element 206, for the inactive door 104, and the lock-point-arming-input-element 210 for the inactive door 104, together with a torsion spring 356, which is operatively attached between the inactive door lock-point arming input element 210 and the frame 336 of the inactive door locking apparatus 184, for urging the lock-point arming input element 210 toward the armed D position thereof.

As will be understood from an examination of
With the lock-point arming input element 210 in its armed position, interaction between the sidewalls of the notch 426 in the drive rail linkage 358, the locking cam portion 422 of the input arming element 210, is transferred to a corresponding interaction between the key 418, of the input arming element 210 and the sidewalls of the inverted-keyhole-shaped hole 420 in the first side plate 339 of the frame 336, in such a manner that the handle-actuated input-drive element 206 cannot be used for retracting the first and second lock-point actuation slides 350, 352 and the drive rail linkage 358, until the input arming element 210 is first rotated from the armed position D to the disarmed position E thereof, and held in the disarmed position E thereof, via the thumb turn 200 as either the inside or outside handle 198, 202 is moved downward from the intermediate position B to the first position A thereof.
It will be noted, by those having skill in the art, that the input arming element 210, of the inactive locking apparatus 184, does not have a direct connection for moving the lock-point actuation slides 350, 352, but, rather, acts to limit the allowable motion of the inside and outside inactive door handles 198, 202, in a similar manner to that previously described herein above, with respect to the lock-point arming input element 172 in the active door locking apparatus 142.
