The present invention relates to a sidelite assembly having first and second panels and a window. Each of the panels has an inner edge extending outwardly from a major planar portion and surrounding an opening. The inner edge includes a first portion having a ridge extending outwardly from a distal end thereof and a second portion having a channel extending inwardly from the distal end. An outer edge extends outwardly from the major planar portion and adjacent a periphery thereof, and includes a first portion having a ridge extending outwardly from a distal end thereof and a second portion having a channel extending inwardly from the distal end. The ridges of the first panel are aligned with and received in the channels of the second panel. The window is disposed within the opening.
Sidelites and transom lites typically include a window unit having a glass or plastic window retained within a window frame. A solid or hollow core panel having first and second facings and a perimeter frame is provided which is sized to fit an opening adjacent the door. Many conventional designs for sidelight assemblies are thus similar to a design for a narrow door, including similar components to a door only sized to create a relatively narrow panel.
Various designs for compression molded door assemblies are known in the art. Some designs include a pair of compression molded door panels which include edges which align with and abut one another to form a hollow cavity for receiving a door core.
However, such joints between the two panels tend to pull apart when the cavity of the door is foamed due to the pressure exerted by the foam. Butt joints are also not as durable if exposed to thermal fluctuations.
Other door assembly designs provide for a pair of compression molded door panels including edges which align and foil a lap joint. The first and second panels have different but complementary edges. As such, a separate mold is required for each panel, thereby increasing manufacturing costs.
Some door assembly designs include a window unit disposed within a cutout formed in first and second aligned molded panels. The panels are secured to a perimeter frame, forming a cavity between the two panels. Foam or other core material may be provided within the core. The cutout is formed in the panels by removing a central portion of both panels as well as the foam or core material therebetween. The window unit is then secured within the cutout. Such designs result in a considerable amount of waste given the cutout may represent 40% or more of the entire panel. Such designs may also be relatively expensive and complex to manufacture.
Other designs provide for specially formed first and second door panels which include molded inner edges for retaining a window unit. Such designs include a first panel having a configuration different from but complementary to a second panel. As such, manufacturing costs for such designs are relatively high given a dedicated die mold is required for each panel. In addition, many such designs fail to provide interlocking joints which maintain their integrity during foaming. As a result, foam tends to leak out between the two panels, rendering the door commercially unacceptable.
Conventional door assembly designs have not proven adequate as a sidelite design. Therefore, there is a need for a sidelite assembly that overcomes some or all of the above-noted problems, is relatively inexpensive to manufacture, and is relatively simply to assemble.
In accordance with a first aspect of the invention, a sidelite assembly is provided. The assembly features first and second panels having first and second major planar portions, respectively, that collectively define an opening for receiving a glazing panel. The first panel features a first inner edge portion and a first outer edge portion extending from the first major planar portion. The first inner edge portion surrounds the opening and includes an inner edge ridge extending from a distal end of the first inner edge portion. The first outer edge portion is positioned adjacent to a periphery of the first major planar portion and includes an outer edge ridge extending from a distal end of the first outer edge portion. The first panel further features a first extension edge portion including a first parallel leg extending parallel to the first major planar portion and a first perpendicular leg extending perpendicular to the first parallel leg, the first extension edge portion including an extension ridge extending from a distal end of the first extension edge portion. The second panel features a second inner edge portion and a second outer edge portion extending from the second major planar portion. The second inner edge portion surrounds the opening and has an inner edge channel extending into a distal end of the second inner edge portion. The second outer edge portion is positioned adjacent to the periphery of the second major planar portion and has an outer edge channel extending into a distal end of the second outer edge portion. The second panel further features a second extension edge portion including a second parallel leg extending parallel to the second major planar portion and a second perpendicular leg extending perpendicular to the second parallel leg, the second extension edge portion including an extension channel extending into a distal end of the second extension edge portion. The inner edge ridge and the outer edge ridge are received in the inner edge channel and the outer edge channel, respectively, to align the first and second panels with one another and form a cavity between the first and second major planar portions. The extension ridge is received in the extension channel, and the first and second extension edge portions are removable from the panels without disturbing the cavity.
A second aspect of the invention provides a sidelite assembly including first and second panels having first and second major planar portions, respectively, that collectively define an opening for receiving a glazing panel. The first panel features a first inner edge portion and a first outer edge portion extending from the first major planar portion, the first inner edge portion surrounding the opening, the first outer edge portion positioned adjacent to a periphery of the first major planar portion. The first inner edge portion includes a first inner edge ridge on a first half of the first panel relative to an imaginary longitudinal centerline and has a first inner edge channel on a second half of the first panel relative to the imaginary longitudinal centerline. The first outer edge portion includes a first outer edge ridge on the first half of the first panel relative to the imaginary longitudinal centerline and has a first outer edge channel on the second half of the first panel relative to the imaginary longitudinal centerline. The second panel features a second inner edge portion and a second outer edge portion extending from the second major planar portion, the second inner edge portion surrounding the opening, the second outer edge portion positioned adjacent to a periphery of the second major planar portion. The second inner edge portion includes a second inner edge ridge on a first half of the second panel relative to the imaginary longitudinal centerline and has a second inner edge channel on a second half of the second panel relative to the imaginary longitudinal centerline. The second outer edge portion includes a second outer edge ridge on the first half of the second panel relative to the imaginary longitudinal centerline and has a second outer edge channel on the second half of the second panel relative to the imaginary longitudinal centerline. The first and second panels further collectively form a removable extension edge. The first inner edge ridge and the first outer edge ridge are received in the second inner edge channel and the second outer edge channel, respectively, and the second inner edge ridge and the second outer edge ridge are received in the first inner edge channel and the first outer edge channel, respectively.
According to additional aspects of the invention, door and sidelite assemblies are provided.

A cavity 50 is formed between connected panels 12, 14, which may be filled with a foam core material such as polyurethane foam or expanded polystyrene. Alternatively, a solid core formed from a composite wood material, cardboard, or the like may be provided.
As shown in
As shown in
Therefore, the same panel 12 (or 14) may be used for both panel halves (12, 14) of sidelite assembly 10. It will be understood to one skilled in the art that other arrangements of ridges 26, 40 and channels 32, 46 may be provided on panel 12 (or 14) such that one panel 12 may be inverted or rotated and align with another panel 12 for securing ridges 26, 40 within channels 32, 46.
The specific dimensions of ridges 26, 40 and channels 32, 46 may vary depending on the material used to form panels 12, 14, the core material used, the dimensions of sidelite assembly 10, and other like processing considerations. Preferably, ridge 26 has a slightly smaller height and width compared to channel 32. Ridge 26 may also include a rounded apex 64. The width of ridge 26 may narrow as it extends outwardly to apex 64. Ridge 40 may have similar dimensions.
Channel 32 preferably has a complementary configuration for receiving ridge 26. For example, channel 32 may include a U-shaped configuration in cross-section for receiving apex 64 of ridge 26. However, channel 32 preferably has slightly larger dimensions compared to ridge 26 to provide for adequate tolerance between ridge 26 and channel 32. Tolerance between ridge 26 and channel 32 should provide sufficient clearance such that interference between ridge 26 and channel 32 is minimized. In addition, the slightly larger dimension of channel 32 allows space for adhesive, which may be used to secure panel 12 to panel 14. Channel 46 may have similar dimensions.
Although adequate clearance between ridge 26 and channel 32 should be provided to avoid tolerance problems, ridge 26 should be fit within channel 32 sufficiently snug so that ridge 26 is not forced or pulled out from channel 32 either during or after manufacture, including during foaming. When foam is injected into cavity 50, pressure is exerted against inner and outer edges 22, 34. Ridge 26 is sufficiently secured within channel 32, and ridge 40 within channel 46, such ridges 26, 40 and channels 32, 46 act as darns during foaming when panels 12, 14 are mated. Ridges 26, 40 push against the sides of channels 32, 46 during foaming, thereby creating a foam tight seal between panel 12 and panel 14.
Preferably, each panel 12, 14 includes at least one U-shaped pocket 66 disposed intermediate inner and outer edges 22, 34, as best shown in
When inner and outer edges 22, 34 of panels 12, 14 are aligned, pockets 66 are likewise aligned, as shown in

Different door and sidelite units may require sidelite assemblies having differing lengths. For example, the assignee of the present application manufactures some door and sidelite assemblies having openings for receiving a sidelite assembly having a length of about 79 1/4 inch, and another assembly having a length of about 79 inch. Extension edge 34A ensures that sidelite assembly 10 may be used for door and sidelite assemblies requiring differently sized sidelite assemblies. Extension edge 34A may be spaced from outer edge 34 by a predetermined distance. If sidelite assembly 10 is to be installed in a door assembly requiring a sidelite assembly having a lengthy of 79½ inch, sidelite assembly 10 is simply installed in the door assembly opening. However, extension edge 34A may be removed if sidelite assembly 10 is to be installed in a door assembly opening requiring a sidelite assembly having a length of 79 inches.
It will be understood to one skilled in the art that the spacing of extension edge 34A from outer edge 34 may be varied depending on the particular door assembly dimensions. In addition, two or more extension edges 34A may be provided to increase versatility. In addition, an extension edge could be provided along a longitudinal edge of panel 12 (or 14) in order to provide adjustability of width of sidelite assembly 10.
Alternatively, a solid bottom rail R may be provided, which may be trimmed to length. As best shown in

Alternatively, a saddle and glazing beads may be secured to panels 12, 14 surrounding opening 20, such as described in co-pending patent application Ser. No. 10/981744, Publication No. 2005/0193655, the disclosure of which is incorporated herein by reference.
Alternatively, panels 12, 14 may include contoured portions extending inwardly from the plane of major planar surface 18 and into opening 20. An edge of the contoured portion defines opening 20, and abuts either a window frame or window spacer as described more fully in co-pending application Ser. No. 10/851659, Publication No. 2005/0028465, the disclosure of which is incorporated herein by reference.
Regardless of the specific configuration of panels 12, 14 and/or glazing panel 16, inner and outer edges 22, 34 either define or are spaced from opening 20 so that any foam injected into cavity 50 will not leak into opening 20.
