This document pertains generally, but not by way of limitation, to fenestration operation hardware.
Tilt latches are used with some examples of double hung windows to facilitate the tilting of the window sashes. Tilting of the window sashes allows for cleaning of the interior and exterior of the window sash while the operator is located, for instance, indoors. In at least some examples, tilt latches are actuated by the operator by applying hand pressure to tilt latches that are otherwise biased outwardly into the adjacent jambs. Actuation of the tilt latches allows for tilting of the window sash.
In some examples, the operator must simultaneously actuate each of two tilt latches installed on opposite sides of the window sash to enable tilting of the sash. The tilt latches are individually operated and held in a retracted orientation to permit tilting. In other words, the tilt latches are biased into the projected orientation when released and held there while the sash is tilted out of the frame.
The present inventors have recognized, among other things, that a problem to be solved can include eliminating redundant hardware used in separate mechanisms for operating tilt mechanisms and locking and unlocking of sashes for movement within a frame. In an example, the present subject matter can provide a solution to this problem, for instance with an operation hardware assembly that actuates a latch blade to lock and unlock the sashes and actuates latch bolts remotely for tilting within a frame. The operation hardware assembly consolidates tilting and locking/unlocking functions into a single assembly that is actuated with an operator, such as a rotatable handle. Separated mechanisms and independently operated hardware are thereby avoided.
The present inventors have further recognized, that a problem to be solved can include ensuring reliable locking of sashes with fenestration units that are installed out of square and providing reliable opening and closing of the sashes in any combination and locking of the sashes when closed (also in any combination). For instance, a fenestration unit is in some examples unintentionally installed out of square and locking features at the edges of the sashes and along the frame are not aligned and accordingly do not lock the sashes. In other examples, the sashes of a window assembly are unlocked and opened in a specified pattern (e.g., top sash first followed by the bottom sash) to prevent triggering of one or more autolocking features.
In an example, the present subject matter can provide a solution to these problems, for instance with a latch blade provided near the operator (e.g., a lever). The position of the latch blade facilitates the maintenance of the position of the latch blade with a blade recess of the opposed sash even with out of square installations. For instance, with an out of square installation the perimeter components of the fenestration assembly, such as the frame, edges of the sashes or the like experience greater misalignment than the interior components provide along the checkrails. In contrast, the latch blade provided along the check rail (e.g., near an operator such as a lever) is readily maintained in alignment with the corresponding blade recess because out of square variations in position are less pronounced in the interior of the fenestration assembly (e.g., relative to the remote assembly perimeter).
Further still, the operation hardware assembly described herein includes a retention assembly that maintains the latch blade in a withdrawn position (e.g., thereby unlocking the sashes) while the sashes are closed and throughout movement of one or more of the sashes to open positions. The retention assembly is opening neutral, and thereby allows the user to open either or both of the sashes in any order (either of the top sash or bottom sash opened first) without releasing the latch blade from its withdrawn position. Instead, the operation hardware assembly releases the latch blade into the locked configuration (e.g., with the blade deployed and received in a blade recess of the opposed sash) upon closing of both sashes where at least one of the sashes was previously open. Accordingly, the user may readily open either of the sashes with the unlocked fenestration assembly without the risk of triggering relocking of the latch blade.
This overview is intended to provide an overview of subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the invention. The detailed description is included to provide further information about the present patent application.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
This hardware systems described herein utilize at least one latch blade that projects orthogonally to the direction of sash travel from a first sash (e.g., bottom) into a strike recess in the second sash (e.g., top). The extension of the latch blade from the bottom sash into the top sash immobilizes both sashes and creates a locked condition. The latch blade includes, but is not limited to, a blade, tongue, plate, bar, post or the like configured to deploy from the first sash for reception in the second sash and thereby lock the first and second sashes. The latch blade provides a distributed member configured for reception within a corresponding opposed recess to institute reliable secure locking of the sashes. Additionally, the latch blade and the blade recess cooperate to ensure reception of the latch blade within the recess even with settling of one or more of the sashes, out of square installations or the like. The latch blade and recess are, in one example, installed toward the interior portion of the sashes where variations due to out of square installations are minimal (in comparison to the perimeter of the assembly), and the latch blade and recess are optionally dimensioned with a taper, enlarged recess or the like, respectively, to promote reception in less than ideal circumstances.
In one example, the latch blade is driven by an eccentric cam coupled with an operator interface feature, such as a lever. The cam is rotated by the operator interface feature to reciprocate the blade between deployed (locked) and withdrawn (unlocked conditions). In another example, the latch blade is biased by a biasing element (e.g., toward the deployed locked condition) and a cam follower of the latch blade (e.g., a slot) is used as a cam to correspondingly rotate the operator interface feature toward the initial locked condition. The operator interface feature coupled with the operation assembly described herein is the point of interaction for the used, and resembles a traditional cam type lock operator.
Further, the fenestration hardware system also configures the fenestration assembly for tilting of at least the bottom sash. A tying element, such as a cord, connects one or more of left or right bottom sash tilt latches. The tying element is routed directly across a spool and between spool legs. In an example, the spool includes the cam described herein. Spool legs on a spool face of the spool engage the tying element (e.g., in a wrapping zone) when the handle is moved to the tilt position (and the spool is moved out of a passive, non-wrapping zone). In the tilt position, a portion of the tying element is wrapped around the spool legs thereby shortening the cord length between the latch bolt assemblies and causing the latch bolts to withdraw from latch bolt recesses of a fenestration frame. With the latch bolts withdrawn the sash is tiltable relative to the fenestration frame.
In another example, the fenestration hardware assembly is configured for automatic locking (e.g., autolocking), that returns the system to a locked condition upon closing of the sashes (in any order). A retaining mechanism within the lock handle assembly restrains the handle in the unlocked position, until the release assembly is activated when both sashes are closed. The release assembly is composed of a moveable trigger surface (e.g., a release element having a release head), that moves perpendicular to the direction of sash travel. The release mechanism further includes a plunger that engages the release element head and a projecting surface configured to engage the opposed sash. As the sashes are closed the plunger interacts with a striker button on the opposed sash (e.g., the top sash). As the sashes are further closed the plunger head is moved with the movement and drives the release element orthogonally relative to the direction of sash travel. The detent of the detent element is unseated from one or more detent notches of the operator interface feature and the interface feature and the latch blade are freed to return to the locked configuration (e.g., with the lever moving to the locked position and the latch blade moving to the deployed position). Because this function is triggered with closing of the sashes the deployed latch blade is automatically received within the blade recess of the blade socket and the sashes are accordingly locked while closed.
The example fenestration hardware assemblies described herein are improvements over conventional cam type locks in several ways. The examples utilize retaining and releasing features that automatically operate the hardware to lock the sashes and reset the system for use (locking) upon opening of the sashes. This ensures an adequate weather seal is established when the sashes are closed. Further, the retaining mechanism also prevents movement of the lock handle to the locked position while the sashes are open. Accordingly damage to the sashes is prevented that may otherwise occur with an unintentionally deployed latch blade. Further, the example fenestration hardware assemblies are fashioned with a traditional aesthetic. The mechanisms are concealed in a housing and the sash and the hardware thereby appears similar to a sweep and keeper lock. However, the fenestration hardware assemblies further control automatic locking of the sashes and tilting. Further still, the fenestration hardware assemblies described herein provide the latch blade at a position remote from the perimeter of the fenestration assembly. Accordingly, variations in the placement of components (e.g., due to out of square installations) are mitigated for the fenestration hardware assembly because the components are remote relative to the perimeter where shifting due to installation variations is most pronounced.
Stated another way, the operation hardware assembly and the blade socket locations, shapes and operation alleviates sensitivity to product installation and manufacturing variations.

As previously described, one or more tying elements 214 extend from the operator housing 204 to one or more corresponding latch bolt assemblies 206 provided at the ends of the sash check rail 114. Continued rotation of the operator interface feature 202, for instance, beyond the unlocked configuration moves the tying elements 214 and accordingly withdraws the latch bolts of each of the latch bolt assemblies 206 out of corresponding latch bolt recesses 118 shown, for instance, in
As further shown in
The operator interface feature 202 is configured to move and accordingly operate each of the spindle 300, spool 302 and the latch blade 304. For instance, in one example, the operator interface feature 202 is fixed rotationally relative to the spindle 300. For instance, the spindle 300 is a component of the operator interface feature 202 and coupled with a shaft, feature or the like that facilitates the transmission of rotational movement from the user operable portion of the operator interface feature 202 (e.g., a handle) to the spindle 300. In one example, the spindle 300 includes one or more spindle legs configured for engagement with one or more spool legs described further herein. The spool legs, in one example, are coupled with the spool 302. Interfitting of the spool legs and the spindle legs of the respective spool 302 and spindle 300 facilitates the transmission of rotation from the operator interface feature 202 to the spool 302. In various examples, the spindle legs and spool legs are, in one example, forks, tines, wedges or the like configured to engage and transmit rotation from the spindle 300 and the operator interface feature 202 to the spool 302 to move the latch blade 304 between the withdrawn and deployed configurations.
In one example, the spool 302 includes a cam, such as a pin, cam element or the like provided on an opposed surface of the spool 302 and coupled with a cam follower of the latch blade 304, such as a cam slot. Accordingly, rotation of the operator interface feature 202 is transmitted through the spindle 300 and the spool 302 to translate the latch blade 304 between the deployed position shown in
As further shown in
As further shown in
In another example, the operator assembly 200 includes one or more features configured to facilitate resetting of the operator assembly 200 to automatically lock the assembly 200 and the corresponding sashes such as the first and second sashes 104, 106 with positioning of each of the sashes in the closed configuration, for instance, with the closed positions shown in
In another example, the operator assembly 200 includes one or more partitions, screens, baffles or the like configured to prevent unintentional interaction with one or more of the auto locking features, for instance, the plunger 306. In the example shown in
In a further example, the latch blade 304 includes one or more tapered features configured to facilitate the reception of the latch blade 304 for instance, during auto locking within the blade recess 210, with out of square assembly 100 installations or the like. The latch blade 304 including the blade taper 316 is readily received within the blade recess 210. The blade socket 208 including the blade recess 210 is, when the sashes 104, 106 are closed, aligned with the operator assembly 200. Accordingly, with movement of each of the sashes 104, 106 to a closed position, the deploying latch blade 304 is received within the blade recess 210. In some examples, the upper sash, for instance, the second sash 106 shown in
Additionally, the blade taper 316 enhances the reception of the latch blade 304 within the blade recess 210 with out of square installation, for instance, with one or more of the fenestration frame 102, sashes 104, 106 out of square with each other, the wall or the like. Because the blade recess 210 has a relatively large profile in comparison to the tapered tip of the latch blade 304 the blade 304 is readily received in the recess 210 even where there is some installation-based misalignment between the recess 210 and the latch blade 304.
Further, although the latch blade 304 is described as a blade, in other examples the latch blade 304 includes, but is not limited to, a tongue, plate, bar, post or the like configured to deploy from the operator assembly 200 for reception in a recess, such as the recess 210, of the opposed sash to lock the sashes 104, 106.
In operation, the strike button 212 remains in a projecting configuration relative to the blade socket 208. As the sashes 104, 106 are moved toward respective closed positions the plunger 306, in one example, is engaged with the strike button 212. Engagement between these two components biases the plunger 306 upwardly, for instance, in an opposed fashion relative to the bias provided by a biasing element associated with the plunger 306. The plunger 306 accordingly engages with components (e.g., other components of a release assembly) within the operator housing 204 including, for instance, a release element, a detent element or the like to release the operator interface feature 202 and release the operator assembly 200 to move toward a locking configuration, for instance, with the latch blade 304 deployed and received within the blade recess 210. Additionally, because the strike button 212 is positioned adjacent to the blade recess 210 as shown in
In the view shown in
As will be described herein, the spindle 300 includes one or more features configured to transmit rotation and initiate resetting of one or more of a retaining mechanism or release assembly. In this example, the spindle 300 includes a spindle reset 600 as well as one or more detent notches configured to receive a detent and accordingly hold the operator interface feature 202 in the unlocked position. The spindle 300 further includes one or more interfitting features, such as spindle legs described further herein, configured to interfit with one or more corresponding spool legs 622 shown, for instance, in
As further shown in
The operator assembly 200 further includes a release assembly configured to interact with the retaining mechanism (e.g., the detent element) and thereby release the assembly 200 to auto lock. The release assembly in one example includes a release element 604 is further provided as a component of the retaining mechanism configured to release retention of the operator interface feature 202, for instance through selective engagement and movement of the detent element 602. In the example shown in
As further described herein, the spindle 300 optionally includes a spindle reset 600. The spindle reset 600 engages with one or more components of the operator assembly 200, such as the release element 604, to selectively reset the assembly 200 and allow the detent element 602 to move toward the operator interface feature 202 (e.g., with bias provided by a detent biasing element 610, such as a leaf spring).
As further shown in
In operation, translation of the tilt stop button 312, for instance depression, moves the tilt stop bar 612 out of alignment with a tilt stop recess 618 and frees the operator interface feature 202 to rotate beyond the unlocked position. Rotation of the operator interface feature 202 toward the tilting position (see

In the proceeding
Referring again to
As further shown in
In this configuration, the release element 604 is positioned in an offset or misaligned configuration relative to the plunger 306. Additionally, one or more components of the plunger 306 are provided at an elevated position relative to a position of the plunger while one or more of the sashes 104, 106 are open. In this configuration, at least a portion of the plunger 306 resides within a location otherwise occupied by the release element 604 while the plunger 306 is depressed (e.g., biased away from the release element) as described herein.
As further shown in
As further shown in
As previously described, the spindle 300 is rotated through operation of the operator interface feature 202. Rotation of the spindle 300 is transmitted by interfitting features including, but not limited to, the spindle legs 1000 and spool legs 622 of the spool 302. The spool 302 is shown in
As previous described, the cam 1002 optionally includes an active face 1003 and a passive face 1005. As shown in
The passive face 1005 of the cam 1002 is optionally used to minimize deployment and partial deployment of the latch blade 304. Referring again to
Instead of a round cam, the cam 1002 having optional active and passive faces 1003, 1005 shown in
As further shown in
Referring now to
Because the release head 1006 is aligned with the plunger head 1004 of the plunger 306 and biased toward the aligned position upward movement of the plunger head 1004 displaces the release element 604 in a guided manner toward the detent element 602. In one example, corresponding tapered surfaces at each of the plunger head 1004 and the release head 1006 guide the engagement therebetween and further guide displacing movement of the release element 604 toward the detent element.
Movement of the release element 604 is transmitted to the detent element 602 (as shown with the dashed arrow in
Referring now to
With the retaining mechanism and release assembly the operator assembly 200 is configured to unlock each of the sashes 104, 106 and release the sashes for a slideable movement within the fenestration frame 102 while at the same time retaining the operator interface feature 202 in the unlocked configuration. With closing of the sashes 104, 106, the engagement between the plunger 306 and the release element 604 automatically releases the operator interface feature 202 and the latch blade 304 and allows the latch blade to deploy, for instance, into the blade recess 210 (see
In another example, the operator biasing element 608 (and an optional latch blade biasing element) is absent from the fenestration hardware assembly 116 and the operator assembly 200 (of the assembly 116). In this example, as the sashes 104, 106 are closed, the plunger 306 (e.g., the plunger head 1004) engages with and moves the release head 1006 of the release element 604. As previously described, this biases the detent 900 out of the detent notches 902 and frees the operator interface feature 202 to rotate. The operator (e.g., the user) rotates the operator interface feature 202 toward the locked position (shown in
In yet another example, the retaining mechanism and release assembly are absent from the fenestration hardware assembly 116 and the operator assembly 200. The operator interface feature 202, the spindle 300, the spool 302 and the latch blade 304 are included while the detent element 602, the release element 604, the plunger 306 and other associated elements are removed. In this example, the fenestration hardware assembly 116 is manually operated to transition between the locked, unlocked and tilting configurations. For instance, the operator (user) rotates the interface features 202 between each of these positions with either or both of the sashes 104, 106 in the open or closed positions. This provides additional flexibility to the operator to use the fenestration assembly 100 as desired. Further, one or more additional features are absent in this alternative configuration. For instance, the tilt stop button 212 is absent because the plunger 306 is absent in favor of manual locking.
Optionally, the tilt stop features, including the tilt top button 312, the tilt stop bar 612, tilt stop recess 618 or the like are included in either of these alternative configurations to constrain movement of the operator interface feature 202 toward the tilting position (e.g., as shown in

Referring again to
In another example, the latch blade biasing element 1800 is provided with the latch blade 304 whether alone or in combination with the spindle biasing element previously described herein. As shown, the latch blade biasing element 1800 is configured to bias the latch blade 304 toward the deployed position corresponding to the locked configuration of the fenestration hardware assembly 116. In a manner similar to the spindle biasing element, the latch blade biasing element 1800 moves the cam 1000 and cam follower 624 and accordingly rotates the spool 302. Rotation of the spool 302 is transmitted to the spindle 300 and correspondingly transmitted to the operator interface feature 202. Accordingly, the operator assembly 200, in another example, includes one or more of biasing of the operator interface feature 202 and the latch blade 304 with the latch blade biasing element 1800, the spindle biasing element 608 previously described herein, both of these biasing elements or the like.
At 1902 the method 1900 includes unlocking first and second sashes. For instance, the sashes 104, 106 shown in
At 1910 the method 1900 further includes sliding one or both of the first or second sashes 104, 106 in any order into open positions (including opening one of the sashes and not the other). For instance, the method 1900 includes sliding the first sash 104 into an open position, sliding the second sash 106 into an open position before the first sash or sliding one or both of the first or second sashes in any order. Accordingly, the fenestration hardware assembly 116 described herein is configured to unlock and remain unlocked with any permutation of opening of one or both of the first or second sashes 104, 106, including leaving one or more of the first or second sashes 104, 106 in the closed position.
The method 1900 further includes at 1912 sliding one or both of the first or second sashes previously positioned in the respective open positions to closed positions. In one example, sliding either or both of the first or second sashes to the closed positions includes sliding one of the first or second sashes to the closed position, for instance, where the opposed sash is already in the closed position.
At 1914 the method 1900 further includes automatically locking the first and second sashes 104, 106 with the latch blade 304 while the sashes are at the closed positions. In one example, automatically locking the first and second sashes includes engaging a release assembly against the second sash 106 with sliding of either or both in the first or second sashes 104, 106 to the closed positions. At 1918, the retaining mechanism, for instance one or more of detent, detent element engaged with one or more detent notches as described herein, is disengaged from the operator interface feature 202. For instance, the retaining the detent element 602 is disengaged from the spindle 300 of the feature 202 with movement of the release assembly including, but not limited to, one or more of a plunger 306, release element 604 or the like. Disengagement of the retaining mechanism from the operator interface feature 202 includes movement of the release assembly initiated, in one example, by the engagement of the release assembly against a component of the second sash (e.g., the strike button 212) with sliding movement of one or more of the sashes 104, 106 to the closed position.
At 1920, automatically locking the first and second sashes 104, 106 further includes rotating the operator interface feature 202 from the unlocked position, for instance, from the unlocked position shown in
As described herein, rotating of the operator interface feature 202 from the unlocked position to the locked position and translating of the latch blade 304 from the withdrawn position to the deployed position within the blades recess is trigged through the automatic operation of the fenestration hardware assembly 116 initiated by closing of the first or second sashes 104, 106. For instance, in one example of the release assembly is moved by the closing operation and accordingly transmits movement to the retaining mechanism to unseat the retaining mechanism and release the operator interface feature 202. Optionally a biasing element coupled with one or more of the operator interface feature, the latch blade or the like is configured, with freeing of the operator interface feature 202, to rotate the interface feature 202 toward the locked position and deploy the latch blade deployed position. Because deployment of the latch blade is initiated with closing of the sashes 104, 106 the latch blade 304 is automatically deployed into the blade recess 201 of the closed second sash 106 and the sashes are locked.
Several options for the method 1900 follow. In one example, retention of the operator interface feature 202 includes biasing a detent, for instance the detent element 602 including the detent 900 shown in
In another example, sliding one or both of the first or second sashes 104, 106 includes deploying the plunger 306 of the release assembly from the first sash 104 according to sliding movement of one or more of the first or second sashes relative to the other of the second or first sashes. For instance, in one example the plunger 306 includes a plunger biasing element 628 as shown in
In an additional example, the method 1900 further includes transitioning at least the first sash 104 to a tilting configuration. In one example, transitioning of the first sash 104 (or optionally a second sash 106) includes rotating the operator interface feature 202 from the unlocked position, for instance shown in
In yet another example, rotating the operator interface feature 202 from the unlocked position to the locked position and translating the latch blade 304 from the withdrawn position to the deployed position within the blade recess 210 shown in
