Abstract

A window frame assembly includes a frame; a setting block including a block body secured to the frame; and a block lip extending outwards from the block body; a glazing bead secured to the frame and the setting block, a bead rib of the glazing bead positioned between the block lip and the frame, the glazing bead and the frame defining a glazing channel; and a lite defining a first edge, the first edge of the lite inserted into the glazing channel.

Description

TECHNICAL FIELD

This disclosure relates to glazing and window frames. More specifically, this disclosure relates to a setting block and a glazing bead.

BACKGROUND

Windows commonly utilize setting blocks which are placed between the glazing, or the lite, of the window and the frame to prevent contact between the lite and the frame that can result in stress on the lite. If the window is assembled without setting blocks, the lite may prematurely fail in service. Additionally, improper installation of glazing beads can place stress upon the lite which can also result in failure during service or assembly.

DETAILED DESCRIPTION

The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and the previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, and, as such, can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description is provided as an enabling teaching of the present devices, systems, and/or methods in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the present devices, systems, and/or methods described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” can include two or more such elements unless the context indicates otherwise.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.

Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutation of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all aspects of this application including, but not limited to, steps in disclosed methods. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific aspect or combination of aspects of the disclosed methods.

Disclosed is a window frame assembly and associated methods, systems, devices, and various apparatus. The window frame assembly can comprise a frame, a setting block, a glazing bead, and a lite. It would be understood by one of skill in the art that the disclosed window frame assembly is described in but a few exemplary aspects among many. No particular terminology or description should be considered limiting on the disclosure or the scope of any claims issuing therefrom.

FIG. 1 is a detailed cross-sectional view of a window frame assembly 100 comprising a frame 110, a setting block 140, a glazing bead 160, and a lite 180 in accordance with one aspect of the present disclosure. In the present aspect, the frame 110 can be a fixed frame 112 configured to directly receive the lite 180. In other aspects, the frame 110 can be a stile or a rail of an operable sash, as shown and described in further detail below with respect to FIGS. 11-20. In the present aspect, each of the frame 110, the setting block 140, and the glazing bead 160 can be extrusions; however, in other aspects, any or all of the frame 110, the setting block 140, and the glazing bead 160 can be manufactured through a different process such as casting, for example and without limitation.

In the present aspect, the frame 110 can comprise a flange 114 and a web 116, and the web 116 can extend outwards from the flange 114 substantially perpendicular to the flange 114. The frame 110 can comprise a plurality of ribs 118a-f extending outwards from the web 116. The setting block 140 can comprise a plurality of ribs 142a,b extending outwards from a block body 146 of the setting block 140. The setting block 140 can define a setting block groove 144 extending along the block body 146 between the ribs 142a,b, and the setting block groove 144 can be configured to engage the ribs 118a,b, of the frame 110 to secure the setting block 140 to the frame 110.

The glazing bead 160 can comprise a bead body 162 and a bead rib 164, and the bead rib 164 can extend outwards from the bead body 162. In the present aspect, the bead body 162 and the bead rib 164 of the glazing bead 160 can substantially define an L-shape; however, in other aspects, the glazing bead 160 can define a different shape, such as a T-shape for example and without limitation. The bead rib 164 can be configured to slip underneath a block lip 148 of the setting block 140, and a bead barb 168 of the bead rib 164 can engage with a setting block barb 150 of the block lip 148 to secure the glazing bead 160 to the setting block 140. The glazing bead 160 can define a bead groove 166 proximate to an intersection between the bead body 162 and the bead rib 164, and the bead groove 166 can be configured to receive the rib 118c of the frame 110 to secure the glazing bead 160 to the setting block 140 and the frame 110.

The glazing bead 160 and the frame 110 can define a glazing channel 102, and the glazing channel 102 can receive a first edge 182 of the lite 180. In the present aspect, the lite 180 can be an insulating glass unit (“IGU”) 184 comprising a first pane 186a and a second pane 186b spaced apart from one another; however, in other aspects, the lite 180 can be a different type of glazing, such as a single pane, laminated glass, or any other suitable type of glazing or infill. In the present aspect, the glazing bead 160 can comprise a bead weather strip 170 disposed within the glazing channel 102, and the bead weather strip 170 can be configured to engage and deform against the first pane 186a to form a seal between the glazing bead 160 and the lite 180. In the present aspect, the bead weather strip 170 can comprise a rubber material, and the bead weather strip 170 can define a flange portion 172 and a tubular portion 174. The flange portion 172 can be T-shaped in the present aspect, and the flange portion 172 can be captured by the glazing bead 160. The tubular portion 174 can engage the first pane 186a, and the tubular portion 174 can be configured to collapse and elastically deform to exert residual pressure against the lite 180.

The frame 110 can comprise a frame weather strip 120 disposed within the glazing channel 102, and the frame weather strip 120 can be configured to engage and form a seal with the second pane 186b of the lite 180. In the present aspect, the frame weather strip 120 can comprise neoprene rubber, and the frame weather strip 120 can be bonded to the flange 114 of the frame 110, such as with a glue, mastic, epoxy, or any other suitable adhesive. In some aspects, the frame weather strip 120 can be treated with an adhesive, and the frame weather strip 120 can also bond to the lite 180 to form a seal between the lite 180 and the frame 110.

The setting block 140 can be configured to prevent contact between the first edge 182 of the lite 180 and the web 116 of the frame 110 in order to reduce conduction of heat between the lite 180 and the frame 110 and to prevent stress risers along the first edge 182 of the lite 180 caused by thermal expansion and contraction of the lite 180. In some applications, such as along a bottom rail of a sash, the setting block 140 can support the weight of the lite 180. In other applications, such as along a stile of a sash, a gap may be defined between the lite 180 and the setting block 140 to allow for thermal expansion of the lite 180, as shown.

FIG. 2 is a perspective view of the frame 110 of FIG. 1. In the aspect shown, the frame weather strip 120 can be covered by a backing strip 220. The backing strip 220 can cover and protect an adhesive coating applied to the frame weather strip 120. By removing the backing strip 220, the adhesive coating can be exposed in order to bond the frame weather strip 120 to the lite 180 as shown in FIG. 1.

FIG. 3 is a perspective view of the setting block 140 of FIG. 1. The block body 146 can define a first end 310 and a second end 312 disposed opposite from the first end 310. In the present aspect, each of the ribs 142a,b, the setting block barb 150 and the setting block groove 144 can extend from the first end 310 to the second end 312. The block body 146 can also define a first edge 302 and a second edge 304 disposed opposite from the first edge 302. The rib 142b can be disposed at the first edge 302, and the setting block barb 150 can be disposed at the second edge 304. The block body 146 can also define a frame side 306 and a lite side 308 disposed opposite from the frame side 306. In the present aspect, each of the ribs 142a,b and the setting block barb 150 can extend outwards from the frame side 306 of the block body 146, and the setting block groove 144 can extend along the frame side 306. In the present aspect, the lite side 308 can be substantially planar; however, in other aspects, the lite side 308 can define a different shape, such as a grooved shape, a rounded shape, or any other suitable shape, for example and without limitation.

In the present aspect, the rib 142a can be a block toe rib 342a, and the rib 142b can be a block heel rib 342b. The block toe rib 342a can define a lip 346 which extends back towards the first edge 302 to partially enclose a toe pocket portion 348 of the setting block groove 144. In the present aspect, the block heel rib 342b can define a substantially rectangular cross-section; however in other aspects, the block heel rib 342b can define a lip extending towards the second edge 304, as shown and further described below with respect to FIG. 10. In other aspects, the block heel rib 342b can define a different cross-sectional shape, such as L-shaped, triangular, trapezoidal, C-shaped, or any other suitable shape, for example and without limitation.

FIG. 4 is a perspective view of the glazing bead 160 of FIG. 1. The bead body 162 can define a first end 402 and a second end 404 disposed opposite from the first end 402. In the present aspect, the bead rib 164 can extend along the bead body 162 from the first end 402 to the second end 404. The bead body 162 can also define a first edge 410 and a second edge 412 disposed opposite from the first edge 410. In the present aspect, the bead rib 164 can be disposed proximate to the second edge 412, and the bead groove 166 can be defined at the second edge 412. The bead body 162 can further define a first side 406 and a second side 408. The bead rib 164 can extend outwards from the first side 406 of the bead body 162, and the first side 406 can partially define the glazing channel 102, as shown in FIG. 1.

A pair of ribs 472a,b can also extend outwards from the first side 406, and the pair of ribs 472a,b can define a T-slot 470 configured to receive the flange portion 172 of the bead weather strip 170. In the present aspect, the bead weather strip 170 is shown partially slid out of the T-slot 470 towards the second end 404 of the bead body 162 to more clearly shows the details of the ribs 472a,b and the T-slot 470.

FIG. 5 is an end view of the frame 110 of FIG. 1. The flange 114 can define a first edge 502 and a second edge 504 disposed opposite from the first edge 502. The flange 114 can also define a first side 510 and a second side 512 disposed opposite from the first side 510. In the present aspect, the web 116 can extend outwards from the first side 510 of the flange 114, and the frame weather strip 120 can be attached to the first side 510. The flange 114 can also define a pair of lips 514a,b disposed at the first edge 502 and the second edge 504, respectively, and the lips 514a,b can extend outwards from the first side 510 of the flange 114.

The web 116 can define a first end 506 and a second end 508 disposed opposite from the first end 506. The first end 506 of the web 116 can be attached to the flange 114. The web 116 can also define a first side 516 and a second side 517. The first side 516 can face the first edge 502 of the flange 114, and the second side 517 can face the second edge 504 of the flange 114. The ribs 118a-c can extend outwards from the first side 516 of the web 116, and the ribs 118d-f can extend outwards from the second side 517 of the web 116. The ribs 118a,d can be positioned proximate to the first end 506 of the web 116. The ribs 118c,f can be positioned proximate to the second end 508 of the web 116.

The rib 118b can be disposed on the first side 516 between the ribs 118a,c. In the present aspect, the rib 118b can be a frame toe rib 522a, and in the present aspect, the frame toe rib 522a can define a lip 524a which can extend towards the second end 508 of the web 116. The rib 118a can be a frame heel rib 518a, and in the present aspect, the frame heel rib 518a can define a lip 520a extending towards the first end 506 of the web 116. In the present aspect, each of the frame toe rib 522a and the frame heel rib 518a can substantially define an L-shape. The frame toe rib 522a and the frame heel rib 518a can be configured to engage the block toe rib 342a and the block heel rib 342b (ribs 342a,b shown in FIG. 3) to secure the setting block 140 (shown in FIG. 3) to the frame 110, as shown and further described below in FIGS. 6 and 7. The rib 118c can be a bead clip 526a which can be configured to engage the bead groove 166 (shown in FIG. 1) to secure the glazing bead 160 (shown in FIG. 1) to the frame 110. In the present aspect, the bead clip 526a can define a substantially trapezoidal cross-sectional shape, and the bead clip 526a can be swept towards the first end 506 of the web 116 to define an acute groove 528a.

Together, the frame toe rib 522a, the frame heel rib 518a, and the bead clip 526a can define a frame detail geometry 590a. The frame detail geometry 590a can be defined by a framing member configured for mounting glazing, such as a stile or rail of a sash or fixed frame, or any other member. The ribs 118d-f can define a variation of the frame detail geometry 590b. The rib 118f can be a bead clip 526b which can be substantially similar to the bead clip 526a, and the bead clip 526b can define an acute groove 528b similar to the acute groove 528a. The rib 118e can be a frame toe rib 522b which can be similar to the frame toe rib 522a, and the frame toe rib 522b can define a lip 524b which can be substantially similar to the lip 524a. However, the frame toe rib 522b can further define a lip 525 extending towards the first end 506 of the web 116. Similarly, the rib 118d can be a frame heel rib 518b which can be similar to the frame heel rib 518a, and the frame heel rib 518b can define a lip 520b which can be substantially similar to the lip 520a. However, the frame heel rib 518b can further define a lip 521 extending towards the second end 508 of the web 116. In the present aspect, the frame heel rib 518b and the frame toe rib 522b can each substantially define a T-shape. The frame heel rib 518b and the frame toe rib 522b can additionally define a T-slot 570, similar to the T-slot 470 (shown in FIG. 4), and the frame heel rib 518b and the frame toe rib 522b can be configured to optionally mount a second setting block 140 (shown in FIG. 1) or to receive the flange portion 172 of a weather strip similar to the bead weather strip 170 (flange portion 172 and bead weather strip 170 shown in FIG. 4). This flexibility provided by the frame detail geometry 590b can be implemented into modular framing components which can improve manufacturing efficiency and flexibility.

FIG. 6 is an end view demonstrating a first step 600 of a method for assembling the window frame assembly 100 of FIG. 1. In the first step 600, the setting block 140 can be angled relative to the first side 516 of the web 116 so that the second edge 304 of the block body 146 is positioned closer to the first side 516 than the first edge 302 of the block body 146. The frame toe rib 522a can then be inserted into the setting block groove 144, and the lip 524a can be inserted into the toe pocket portion 348 of the setting block groove 144 and engaged with the lip 346 of the block toe ridge 342a as shown.

FIG. 7 is an end view demonstrating a second step 700 of the method for assembling the window frame assembly 100 of FIG. 1. Once the frame toe rib 522a is engaged with the block toe rib 342a, the first edge 302 of the block body 146 can be pivoted towards the first side 516 of the web 116 so that the frame heel rib 518a is inserted into the setting block groove 144 and engaged with the block heel rib 342b. The motion demonstrated in steps 600 and 700 can be similar to the motion of slipping a shoe onto a human foot wherein the setting block 140 is analogous to the shoe, and the frame toe rib 522a and frame heel rib 518a are analogous to the toe and heel of a human foot, respectively. Upon completion of the second step 700, the setting block 140 can be secured to the frame 110. In the present aspect, the setting block 140 can be sized to snap over the frame heel rib 518a; however, in other aspects, such as the aspect shown in FIG. 10, the block heel rib 342b can define a lip 1342 (shown in FIG. 10) which can engage the lip 520a so that the lip of the block heel rib 342b is positioned between the lip 520a and the first side 516 of the web 116. With the setting block 140 secured to the frame 110, a gap 702 can be defined between the setting block barb 150 of the block lip 148 and the first side 516 of the web 116.

FIG. 8 is an end view demonstrating a third step 800 of the method for assembling the window frame assembly 100 of FIG. 1. In the third step 800, the bead rib 164 can be slipped over the bead clip 526a and into the gap 702 (shown in FIG. 7) between the setting block barb 150 of the block lip 148 and the first side 516 of the web 116. The bead rib 164 can define a locking ledge 866 which can be swept towards the bead groove 166, and in the position shown, the locking ledge 866 can rest upon the bead clip 526a.

FIG. 9 is an end view demonstrating a fourth step 900 of the method for assembling the window frame assembly 100 of FIG. 1. In the fourth step 900, the bead rib 164 can be further inserted between the block lip 148 and the first side 516 of the web 116 until the bead barb 168 slips past the setting block barb 150. In the present aspect, the block lip 148 and the bead rib 164 can elastically deflect so that the bead barb 168 can snap or click past the setting block barb 150, thereby resisting removal of the glazing bead 160 from the frame 110 and the setting block 140. Additionally, the second edge 412 of the bead body 162 can be rocked towards the first side 516 of the web 116 so that the bead clip 526a engages the bead groove 166 and the locking ledge 866 engages the acute groove 528a. Engagement between the bead clip 526a and the bead groove 166 as well as the locking ledge 866 and the acute groove 528a can also snap the glazing bead 160 into place, thereby securing the glazing bead 160 to the frame 110 and setting block 140 in a secured position.

The glazing bead 160 can be released by rocking the first edge 410 of the bead body 162 towards the first edge 502 of the flange 114, thereby releasing the bead clip 526a from the bead groove 166 and allowing withdrawal of the bead rib 164 from between the block lip 148 and the web 116. However, with the lite 180 (shown in FIG. 1) positioned in the glazing channel 102 as shown in FIG. 1, compression of the bead weather strip 170 resists this rocking motion, thereby biasing the glazing bead 160 towards the secured position.

FIG. 10 shows an end view of a method for assembling another aspect of the window frame assembly 100 in accordance with another aspect of the present disclosure. The window frame assembly 100 can comprise another aspect of the setting block 140 and another aspect of the frame 110 in accordance with another aspect of the present disclosure. In this aspect of the setting block 140, the block heel rib 342b can define the lip 1342 extending towards the block toe rib 342a. The lip 1342 can be configured to engage the lip 520a of the frame heel rib 518a, as shown in Step 1, Step 2, and Step 3. As shown in Step 2 and Step 3, the block heel rib 342b can slightly elastically deform as the lip 1342 slips over the lip 520a, and the lip 1342 can snap between the lip 520a and the first side 516 of the web 116 to secure the setting block 140 to the frame 110. As shown in Step 4, Step 5, and Step 6 and described above with respect to FIGS. 8 and 9, the glazing bead 160 can snap into engagement with the setting block 140 and the frame 110 with a lite 180 positioned between the glazing bead 160 and the frame 110.

The snapping action of the setting block 140 engaging the frame 110 and the glazing bead 160 engaging the frame 110 and the setting block 140 can provide multiple benefits. First, the snapping action provides tactile feedback to an assembler which indicates to the assembler that the components are secured in position. In other window frame assembly designs which do not offer the tactile feedback of the snapping action, it can be unclear to the assembler when the components are properly set, particularly for an inexperienced or new assembler. For example, in some window frame assemblies, glazing beads can be installed by tapping the glazing beads into place with hammer, such as a rubber mallet. In some instances, the assembler may overstress the glazing bead or the lite by continuing to pound on the glazing bead once it has already been set or by pounding excessively hard on the glazing bead. Overstressing the components of other window frame assemblies can lead to failures during assembly, installation, or service. By providing positive tactile feedback that the setting block 140 and glazing bead 160 are properly set, these failures can be prevented.

Similarly, another common point of failure occurs when the assembler of other window frame assembly designs fails to install setting blocks between the lites and frames. In such instances, the assembler may install an inadequate quantity of setting blocks or may entirely forget to install setting blocks at all. Such mistakes place additional stress on the lites which can ultimately lead to failure of the lites in service. With the present window frame assembly 100, if the assembler neglects to install setting blocks 140 into the frame 110, the glazing bead 160 will not snap into and engage the frame 110 without the setting block 140 in place. In such an instance, the absence of positive tactile feedback produced from the improper installation of the glazing bead 160 can alert the assembler that an assembly error has occurred, thereby allowing the assembler to correct the issue before the window frame assembly 100 can leave the shop.
