This document pertains generally, but not by way of limitation, to operation hardware for fenestration assemblies.
Fenestration assemblies include hardware such as window drive mechanisms to facilitate opening of the window by the operator. Casement windows, awning windows, venting picture windows and the like are examples of fenestration assemblies with hardware used to open a panel, such as a sash (and similarly a door). The panel of the fenestration assembly rotates from a closed position to an open position with respect to the fenestration frame. The hardware includes a user input, such as a crank, that actuates a hardware mechanism to move the window between the open and closed positions. In some examples, the hardware is coupled along the sill of the window assembly for access by the operator.
In some examples, the crank is removed from the remainder of the hardware when not in use. For instance, the crank is left on a sill of the fenestration assembly, stored in a drawer or the like. In other examples, the crank remains coupled with the remainder of the hardware and is used for future opening or closing of the fenestration panel.
The present inventors have recognized, among other things, that a problem to be solved can include minimizing large profiles of hardware used with fenestration assemblies including windows and doors. In some examples, hardware extends significantly beyond the profile of the fenestration frame and protrudes away from fenestration assembly. For example, the hardware extends away from the fenestration frame to provide clearance for the handle and knob configuration used to actuate the operator mechanism, for instance like a crank. The protruding hardware interferes with window treatments, like drapes, curtains, shades or the like. Additionally, the installed hardware extends away from the frame during shipping, is damaged during shipping, and in some examples causes damage to adjacent fenestration assemblies (including glass panes) stored against the hardware. Further, because the hardware is prominently placed along the window frame (e.g., proximate the middle of the sill) the hardware detracts from the appearance of the rest of the window including finished wood, painted sills, panels or the like, and in some examples extends into the daylight opening of the fenestration assembly. In another example, the hardware interrupts the finished appearance of the window frame and provides an unappealing distraction from a minimized and sleek aesthetic.
The present subject matter provides a solution to this problem, with operator assemblies including configurable components that minimize the operator assembly profile while maintaining or even enhancing the functionality of the assembly relative to previous hardware. The operator assemblies described herein include an escutcheon and a handle linkage coupled with the escutcheon. The handle linkage includes a handle arm rotatably coupled with the escutcheon, and a handle knob coupled with the handle arm by way of an articulating joint. The handle linkage is configurable between at least stowed and operational configures through manipulation of the handle linkage. For instance, one or more of articulating at the articulating joint and seating of the handle linkage along the escutcheon facilitate compact storage of the handle linkage. The handle linkage, in the stowed configuration, assumes a handle linkage profile similar to the profiles of the escutcheon and the underlying fenestration assembly (e.g., elongate, having a planar contour or the like). The stowed configuration of the handle linkage with the handle knob and the handle arm aligned minimizes bends, elbows or the like in other hardware that enlarges the hardware profile and frustrates low profile stowing of the hardware. Instead, the operator assemblies described herein include an operator profile including a seat profile of the escutcheon and a minimized handle linkage profile that corresponds to the seat profile. In an example, each of the operator profile and the seat profile include planar contours that extend along a corresponding planar contour of the fenestration assembly (e.g., the fenestration frame). Accordingly, the operator profile corresponds, and thereby blends, with the fenestration assembly components, such as the fenestration frame.
In another example, articulating of the handle knob into a misaligned configuration with the handle knob at an operating angle relative to the handle arm facilitates operation of the handle linkage to move a fenestration panel (e.g., between opened and closed positions). For example, the handle knob and the handle arm transition from alignment in the stowed configuration to misalignment at the operating angle. The handle knob is rotatable relative to the handle arm while the handle linkage is operated to move the fenestration panel. Accordingly, the handle linkage is used in a manner similar to a crank having an upstanding rotatable handle knob, and is also reconfigurable to the stowed configuration with the handle knob and the handle arm aligned.
In other examples, the operator assemblies described herein include one or more features configured to facilitate the alignment and seating of the handle linkage in the stowed configuration. In one example, guide elements are provided with the handle linkage and the escutcheon. The guide elements (e.g., sockets, grooves, plugs, ridges, bosses or the like) are coupled with each other as the handle linkage transitions from the operational configuration to the stowed configuration. The coupling of the guide elements guides the handle knob and handle arm into alignment while seating the handle linkage along the escutcheon. In one example, the handle linkage self-seats itself along the escutcheon to facilitate stowing of the linkage.
In another example, the operator assemblies described herein, include one or more bias elements including, but not limited to, detents, magnets or the like that guide the handle knob and handle arm into alignment. For instance, the one or more bias elements are positioned away from a linkage pin axis the handle knob rotates around. Rotation of the handle knob and the handle arm toward alignment brings the bias elements into proximity and initiates further bias by the bias elements to complete the alignment. The bias provided by the bias elements resists further rotation of the handle knob away from alignment. Accordingly, even with misalignment of the handle knob and the handle arm as the handle linkage is stored the one or more bias elements guide the components into alignment for seating along the escutcheon (e.g., one example of self-seating).
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.

As previously discussed, the operator assembly 100 is operated to actuate an operator mechanism 113 coupled between the panel 110 and the fenestration frame 108. The operator mechanism 113 is shown schematically with dashed lines in
The operator assembly 100 includes a handle linkage 102 extending from a handle pivot 118 to a handle knob 116. In the example shown the handle linkage 102 includes a handle arm 114 coupled at the handle pivot 118 with an operator drive shaft 120. In this example, the handle linkage 102 is a two bar type mechanism. In other examples, the handle linkage 102 includes two or more bars (e.g., in the manner of a three bar linkage or the like). The operator drive shaft 120 is in turn coupled with (or a component of) the operator mechanism 113. As further shown in
As further shown in
The escutcheon includes the escutcheon seat 122 and the seat includes a seat profile 124 having a seat profile 124 that is complementary to a handle linkage profile 126 of the handle linkage 102 (in the stowed configuration) as shown in
In this example, the operator assembly 206 includes a handle 208 and an angled knob 210. In this example, the angled knob is rotatably coupled with the handle 208. The angled knob 210 does not include one or more of the degrees of freedom present with the operator assembly 100 shown in
The handle 208 and the angled knob 210 are coupled along the escutcheon 212. For instance an angled handle profile 214 of the handle 208 including the elbow for the angled knob 210 is coupled along the escutcheon profile 216. The angled knob 210 is received within the relatively deeper escutcheon 212 and the operator assembly 206 accordingly projects from the fenestration frame 202 as shown with the operator profile 218 of the assembly 206 relatively pronounced in comparison to the fenestration profile 220 of the fenestration frame. In comparison, the operator profile 130 of the operator assembly 100, including the handle linkage 126 and the complementary escutcheon seat 122 shown in
As shown in
The handle linkage 102 in the example shown optionally includes a linkage guide 306 configured to guide alignment of the handle knob 116 with the handle arm 114 in the stowed configuration. In one example, the linkage guide is a socket, fitting or the like that cooperates with a complementary shaped feature of the escutcheon 104, such as the guide socket 400 shown in
As further shown in
The seat profile 124, as shown in
An example guide socket 400 is provided with the escutcheon 104. In this example, the guide socket 400 includes a recess having a complementary profile to the linkage guide 306 shown in
In another example, the handle shelf 402 cooperates with the guide socket 400 and the seat profile 124 to securely retain the handle linkage 102 along the escutcheon when not in use. For instance, each of the handle shelf 402, guide socket 400 and the seat profile 124 are correspondingly fit with opposed components of the handle linkage 102, including one or more of the edge of the handle linkage 102 (for the handle shelf), the linkage guide 306 (for the guide socket) and the handle linkage profile 126 (for the seat profile 124).
As further shown in
When assembled the arm and knob interfaces 304, 302 are coupled with each other, and the linkage pin 500 facilitates rotation of the handle knob 116 relative to the handle arm 114, for instance to transition the handle linkage 102 from the stowed configuration to the operating configuration. The linkage pin 500 is provided at an angle, for example along a linkage pin axis 510 transverse (e.g., crossing) to the handle linkage 102 in the stowed configuration. Additionally, the knob and arm interfaces 302, 304 are at angles and cooperate with the linkage pin 500 to guide movement of the handle knob 116 from an aligned orientation in the stowed configuration to the angled orientation in the operating configuration.
In one example, one or more bias elements 508 are provided proximate to the articulating joint 132 and the associated interfaces 302, 304. The bias elements 508 retain the handle knob 116 in the stowed configuration until force is applied (e.g., by an operator hand or fingers) to move the knob into a misaligned configuration with the handle arm 114, for instance during operation of the operator assembly 100. Optionally, the bias element 508 of the handle knob 116 cooperates with one or more bias elements 602 associated with the handle arm 114 (an example is shown in

As shown in
As further shown in
The bias element 602 retains the handle knob 116 in the stowed configuration until force is applied (e.g., by an operator hand or fingers) to move the knob into a misaligned configuration with the handle arm 114, for instance during operation of the operator assembly 100. Optionally, the bias element 602 cooperates with the bias element 508 of the handle knob 116 to maintain the handle linkage 102 in the aligned orientation of the stowed configuration or to assist with biasing the handle knob 116 toward the aligned orientation.
The bias elements 508, 602 include, but are not limited to, one or more of a detent, magnet or the like. In the example shown in
In another example, the bias element 508, 602 includes a magnet and the opposed bias element 602, 508 includes a ferrous insert or the like. The magnet and ferrous insert cooperate to guide the handle linkage 102 into the aligned orientation and retain the linkage in the aligned orientation of the stowed configuration until actuation by a user.
Additionally, the handle knob 116 is rotated into an angled orientation relative to the handle arm 114. For example, the handle knob 116 is rotated into a misaligned orientation relative to the aligned orientation of the stowed configuration shown in
In
When operation of the handle linkage 102 is no longer specified the user readily stores the handle linkage 102 along the escutcheon 104 in a compact, low profile manner as described herein. For example, the handle knob 116 is rotated into or near to alignment with the handle arm 114. The handle linkage 102 is then rotated, for instance around one or more of the drive socket 300 or the handle pivot 118 (e.g., with one or more corresponding degrees of freedom) toward the escutcheon seat 122 of the escutcheon 104. The handle linkage 102 is coupled along the escutcheon seat 122, for instance with the handle linkage profile 126 coupling along the seat profile 124. As shown in
