## Title
Modular door lite components

## Abstract

Modular components of modular door lite frame systems are disclosed. In some cases, a modular door lite frame system includes matching first and second modular frames, one or more modular male alignment members, and one or more modular female alignment members. In some cases, the modular alignment members can be coupled to modular frames of various sizes. In some cases, the modular components can be formed by casting ABS between no more than two opposed mold portions.

## Background
BACKGROUND
Technical Field
Modular door lite frame system components and molds for forming such components are disclosed. Molds for forming the components can include at most two opposed mold portions.
Description of the Related Art
Existing frame assemblies for door lites are typically pre-manufactured and shipped to another destination for assembly and installation. For example, door lite frame assemblies can come in two sub-parts, which are secured together with a piece of glass or other transparent or insulating material, such as a glazing panel, between the two sub-parts. There are many existing frame assemblies having different types of external clips or other external fasteners (such as screws) for securing the frame assembly together.
Unfortunately, installation of these existing door lite frames with external fasteners can be time consuming. For example, in some prior door lite frames, when the frame assembly arrives at the place of installation, the frame sub-parts are typically separated by removing fasteners that hold the sub-parts together during transportation. Then during installation, the frame sub-parts are positioned and re-secured together with fasteners. Each fastener that is removed after shipment and re-secured during installation decreases the efficiency of installation, increases costs, and detracts from the aesthetics of the door lite frame.
Door lites without external threaded fasteners have been the subject of U.S. patent applications. For example, U.S. Patent Application Publication No. 2010/0064625 to Charlton et al., the full disclosure of which is hereby incorporated herein by reference in its entirety, describes a door lite frame system. One drawback of such door lite frame systems is that they have been found to be more expensive than desirable to fabricate. There is a need for relatively inexpensive door lite frame systems, components thereof, molds for forming such components, and systems including such components.
BRIEF SUMMARY

In some cases, the first male alignment member is seated within the first recess, the second male alignment member is seated within the third recess, the first female alignment member is seated within the second recess, and the second female alignment member is seated within the fourth recess to allow the first modular frame and the first male alignment member to mate in a shipping arrangement with the second modular frame and the first female alignment member, to allow the first modular frame and the first male alignment member to mate in an installed arrangement with the second modular frame and the first female alignment member, to allow the third modular frame and the second male alignment member to mate in a shipping arrangement with the fourth modular frame and the second female alignment member, and to allow the third modular frame and the second male alignment member to mate in an installed arrangement with the fourth modular frame and the second female alignment member.
In other embodiments, a method of forming door lite frame systems comprises casting a first modular frame between a first top mold portion and a first bottom mold portion, the first modular frame having a first length, a first width and a first recess, casting a second modular frame between the first top mold portion and the first bottom mold portion, the second modular frame having a second recess and dimensions matching those of the first modular frame, casting a third modular frame between a second top mold portion and a second bottom mold portion, the third modular frame having a second length larger than the first length, a second width larger than the first width, and a third recess, casting a fourth modular frame between the second top mold portion and the second bottom mold portion, the fourth modular frame having a fourth recess and dimensions matching those of the third modular frame, seating a first male alignment member within the first recess, a first female alignment member within the second recess, a second male alignment member within the third recess, and a second female alignment member within the fourth recess, the first male alignment member having dimensions matching those of the second male alignment member and the first female alignment member having dimensions matching those of the second female alignment member, mating the first modular frame and the first male alignment member with the second modular frame and the first female alignment member in a shipping arrangement, and mating the third modular frame and the second male alignment member with the fourth modular frame and the second female alignment member in a shipping arrangement.

DETAILED DESCRIPTION
FIG. 1 illustrates an example of a door lite frame system 10 including a modular frame 20 and a modular frame 30. The modular frame 20 is coupled to a plurality of male alignment members 40 and a plurality of male interlocking members 50, each adjacent to a respective male alignment member 40. A male alignment member 40 can include a rectangular shaft extending outward from the modular frame 20. A male interlocking member 50 can include a rectangular shaft extending outward from the modular frame 20 and a plurality of arms 55 extending away from the rectangular shaft toward the respective male alignment member 40. A male alignment member 40 and a respective male interlocking member 50 can together be referred to as a male alignment and interlocking member. The modular frame 30 is coupled to a plurality of female alignment members 60, each female alignment member 60 including a plurality of teeth 65 coupled to a first side of a hollow rectangular shaft opposite a second side of the hollow rectangular shaft. In some embodiments, the modular frame 20 can be identical to the modular frame 30, can have dimensions matching those of the modular frame 30, or can be fabricated from the same mold as used to fabricate the modular frame 30.
FIG. 2 illustrates a corner portion of the modular frame 20 and two male alignment and interlocking members in greater detail. FIG. 3 illustrates a corner portion of the modular frame 30 and two of the female alignment members 60 in greater detail. The female alignment members 60 can include hollow elements which can be configured to receive respective male alignment members 40 in either one of two different orientations. Further, the male and female alignment members 40, 60, can be positioned around the modular frames 20, 30, respectively, such that as the modular frames 20, 30 are brought toward one another, each male alignment member 40 enters a respective female alignment member 60.
For example, the modular frame 20 can be aligned with the modular frame 30 in a first aligned configuration such that the modular frames 20, 30 can be brought toward one another until the male alignment members 40 enter respective female alignment members 60 such that the arms 55 of each male alignment member 40 are adjacent the second side of a respective female alignment member 60, such that the teeth 65 do not engage the arms 55. Such an arrangement can be referred to as an unlocked, shipping arrangement because the modular frame 20 and the modular frame 30 are not locked to one another and can be pulled laterally apart from one another. In such an arrangement, engagement of the male and female alignment members 40, 60 can align the modular frames 20, 30 with one another, such as during transportation of the frame system 10 to an installation location.
As another example, the modular frame 20 can be aligned with the modular frame 30 in a second aligned configuration such that the modular frames 20, 30 can be brought toward one another until the male alignment members 40 enter respective female alignment members 60 such that the arms 55 of each male alignment member 40 are adjacent the first side of a respective female alignment member 60, such that the teeth 65 do engage the arms 55. Such an arrangement is illustrated in FIG. 4 and in greater detail in FIG. 5, and can be referred to as a locked, installed arrangement because the modular frame 20 and the modular frame 30 are locked to one another and cannot be pulled laterally apart from one another without breaking one or more components of the frame system 10. In such an arrangement, engagement of the male and female alignment members 40, 60 can align the modular frames 20, 30 with one another, and engagement of the teeth 65 with the arms 55 can lock the modular frames 20, 30 to one another.
In some embodiments, the modular frames 20, 30 can be progressively brought toward one another and the arms 55 can progressively engage the teeth 65 to progressively lock the modular frames 20, 30 to one another. Thus, in different implementations, the modular frames 20, 30 can be locked together in the locked, installed arrangement with different distances between the modular frames 20, 30. The different distances between the modular frames 20, 30 allow glass or glazing of different thicknesses to be held in place between an inner surface 90 of the modular frame 20 and an inner surface 95 of the modular frame 30, and can likewise allow the frame system 10 to be used with doors or other structures of different thicknesses.
The frame system 10 can be configured such that the orientation of the modular frame 20 in the first aligned configuration is rotated 180° with respect to the modular frame 30 from the orientation of the modular frame 20 in the second aligned configuration. Thus, a method of installing the frame system 10 can include fabricating the individual components of the system 10, coupling the components to one another as shown in FIG. 1, shipping the frame system 10 in the unlocked, shipping arrangement to an installation location, pulling the modular frames 20, 30 laterally away from one another, and coupling the modular frames 20, 30 to one another in the locked, installed arrangement with a window between them. For example, a piece of material such as glass or glazing can be held in place between the inner surface 90 of the modular frame 20 and the inner surface 95 of the modular frame 30.
As illustrated in FIGS. 1-5, a first modular frame 20 of the system 10 can be coupled to male alignment members 40 and male interlocking members 50 but not to female alignment members 60, and a second modular frame 30 of the system 10 can be coupled to female alignment members 60 but not to male alignment members 40 or male interlocking members 50. In other embodiments, however, a first modular frame of a frame system can be coupled to one or more male alignment members 40, one or more male interlocking members 50, and one or more female alignment members 60, and a second modular frame of the frame system can be coupled to one or more male alignment members 40, one or more male interlocking members 50, and one or more female alignment members 60.
In some specific embodiments, a first modular frame of a frame system can be coupled to one or more male alignment members 40, one or more male interlocking members 50, and one or more female alignment members 60, and an identical second modular frame of the frame system can be identically coupled to one or more male alignment members 40, one or more male interlocking members 50, and one or more female alignment members 60, such that the first modular frame and the members coupled thereto are identical to the second modular frame and the members coupled thereto. In some embodiments, the positions of the male alignment members 40, male interlocking members 50, and female alignment members 60 on the first modular frame can correspond to those on the second modular frame such that the first and second modular frames can be coupled to one another in an unlocked, shipping arrangement, and in a locked, installed arrangement as described above.
As illustrated in FIGS. 1-5, a first modular frame 20 of the system 10 can be coupled to male alignment and interlocking members facing the same direction, i.e., such that the male alignment members 40 and the male interlocking members 50 alternate along each side of the modular frame 20. Similarly, the second modular frame 30 of the system 10 can be coupled to female alignment members 60 facing the same direction, i.e., such that the first side of each female alignment member 60 faces the second side of an adjacent female alignment member 60 or such that the first side of each female alignment member 60 does not face a first side of an adjacent female alignment member 60. In other embodiments, however, a first modular frame of a frame system can be coupled to male alignment and interlocking members facing in different or alternating directions. Similarly, a second modular frame of the frame system can be coupled to one or more female alignment members 60 facing in different or alternating directions. In such embodiments, the positions and orientations of the male alignment members 40, male interlocking members 50, and female alignment members 60 on the first modular frame can correspond to those on the second modular frame such that the first and second modular frames can be coupled to one another in an unlocked, shipping arrangement, and in a locked, installed arrangement as described above.
It has been found that a convenient and economical method of fabricating the components of the frame system 10 is doing so modularly. More specifically, it has been found that fabricating a single integral component that includes both of the modular frame 20 and the male alignment and interlocking member or a single integral component that includes both of the modular frame 30 and the female alignment member 60 can be unnecessarily expensive, for several reasons. First, injection molding of such integral members can use complex molds and one or more side pulls, which can increase the cost of the molds and fabrication process. Second, two separate molds are often used—one for the integral component that includes the modular frame 20 and the male alignment and interlocking member and another for the integral component that includes the modular frame 30 and the female alignment member 60—in effect doubling the cost of the already expensive molds. Third, two of such expensive molds are used for each size of door lite to be fabricated. Thus, to manufacture a 24′′×36′′ window, a 28′′×54′′ window, and a 34′′×46′′ window, six expensive molds may be used. In contrast, it has been found that modular fabrication of components of door lite systems can reduce mold costs by greater than 50%, and in some cases, even up to about 75%.
In some embodiments, the modular frame 20 can be formed without the plurality of male alignment members 40 and without the plurality of male interlocking members 50, and the modular frame 30 can be formed without the plurality of female alignment members 60. The plurality of male alignment members 40, the plurality of male interlocking members 50, and the plurality of female alignment members 60 can be formed separately from the other components of the frame system 10. The plurality of male alignment members 40 and the plurality of male interlocking members 50 can then be coupled to the modular frame 20, and the plurality of female alignment members 60 can be coupled to the modular frame 30. The frame system 10 can then be shipped in the unlocked, shipping arrangement to an installation location, the modular frames 20, 30 can be pulled laterally away from one another, and the modular frames 20, 30 can then be coupled to one another in the locked, installed arrangement with a window between them.
In some cases, the modular frame 20 can be formed without the plurality of male alignment members 40 and without the plurality of male interlocking members 50 by injection molding acrylonitrile-butadiene-styrene (ABS) between no more than two opposed mold portions. In some cases, the modular frame 30 can be formed without the plurality of female alignment members 60 by injection molding acrylonitrile-butadiene-styrene (ABS) between no more than two opposed mold portions. In some cases, the plurality of male alignment members 40, the plurality of male interlocking members 50, and the plurality of female alignment members 60 can each be formed separately from the other components of the frame system 10 by injection molding acrylonitrile-butadiene-styrene (ABS) between no more than two opposed mold portions. In some cases, each male alignment member 40 can be formed integrally with a respective male interlocking member 50 but separately from the other components of the frame system 10 by injection molding acrylonitrile-butadiene-styrene (ABS) between no more than two opposed mold portions to form a male alignment and interlocking member.

The dimensions provided in FIGS. 6A-6F, 7A-7F, and 8A-8D have units of millimeters (as do the dimensions provided in all of the Figures), and are examples of dimensions that have been found to be suitable. These dimensions are not intended to limit the scope of the disclosure. As illustrated, a length of the male alignment and interlocking member 100 can be the same as the combined length of the female alignment member 62 and the spacer element 80, such that the male alignment and interlocking member 100 can be mounted interchangeably with the combination of a female alignment member 62 and a spacer element 80 to another portion of a frame system such as a recess of a modular frame.

The first and second modular frames 110, coupled to such components, can form a door lite frame system similar to door lite frame system 10.

The locator tabs 160 can be positioned within the recess 182 to guide a male alignment and interlocking member or a female alignment member and a spacer element into a desired location within the recess 182. FIG. 34 illustrates that the locator tabs 160 can be used in combination with an adhesive such as an ABS structural adhesive 164. In some cases, the ABS structural adhesive 164 can be used without the locator tabs 160. In some cases, the ABS structural adhesive 164 can provide a bond that is at least as strong as, or stronger than, solid ABS material.
FIG. 35 illustrates that a modular frame 184 similar to one of modular frames 110, 120, 130, or 140 can include a plurality of angle elements 166 such as steel angles positioned within its recess 186, similar to one of the recesses 116, 126, 136, or 146. The angle elements 166 can include a bottom leg portion 168 and a top leg portion 170 coupled to the bottom leg portion 168 at a 90° angle. The angle elements 166 can be formed integrally with the modular frame 184 or can be formed separately from the modular frame 184 and coupled thereto, such as with an adhesive positioned between the bottom leg portions 168 and the modular frame 184. Each top leg portion 170 can function in a manner similar to the locator tabs 160, as described above, and can also include a hole 172 for receiving a fastener such as a screw 174. Once components, such as a male alignment and interlocking member, are seated within the recess 186 between two top leg portions 170, screws 174 can be screwed through the top leg portions 170 and into the components to secure them to the modular frame 184. The angle elements 166 can be used in combination with an adhesive such as an ABS structural adhesive, as shown in FIG. 34, or without such an adhesive. In some cases, the angle elements 166 and screws 174 can provide a bond that is at least as strong as, or stronger than, solid ABS material.
In some cases, modular door lite components in accordance with the above description can be provided in systems or kits. For example, a system of modular door lite components can include two modular frames similar to modular frames 20, 30, 110, 120, 130, and/or 140, a male alignment and interlocking member similar to male alignment and interlocking member 100, a female alignment member similar to female alignment member 60, and a spacer element similar to spacer element 80. A door lite system can be assembled from these components.
As another example, a system of modular door lite components can include two modular frames each having a first width and a first length, two modular frames each having a second width and a second length, two male alignment and interlocking members having the same dimensions as one another, two female alignment members having the same dimensions as one another, and two spacer elements having the same dimensions as one another. The first width can be larger or smaller than the second width, and the first length can be larger or smaller than the second length. Two door lite systems having different overall dimensions can be assembled from these components.
The modular door lite components described herein can be used to assemble door lites at less expense than previous door lite systems. The reduced expense can be attributed to at least the modular nature of the components and to reduced manufacturing costs associated with the elimination of side pulls and the use of no more than two opposed mold portions to form the components. The methods, systems, and devices described herein can be used to turn metal frames into energy efficient (thermal break) snap frames.
The various embodiments described above can be combined to provide further embodiments. All of the U.S. patents, U.S. patent application publications, U.S. patent applications, foreign patents, foreign patent applications and non-patent publications referred to in this specification and/or listed in the Application Data Sheet are incorporated herein by reference, in their entirety. Aspects of the embodiments can be modified, if necessary to employ concepts of the various patents, applications and publications to provide yet further embodiments.
These and other changes can be made to the embodiments in light of the above-detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
