Description
- The present invention is directed to a viewport for use with a door or wall, and more particularly, is directed to a frameless viewport for a door of an air handling unit.
- Viewports for doors are desirable as they provide a means to visually perceive what is otherwise hidden by the door without having to open the door. This capability is especially desirable for access doors for air handling units, wherein operation of a ventilation system must typically be interrupted to safely open the access door. Similarly, viewports can be installed in wall panels of an enclosure. Typically, the viewport includes a frame surrounding one more panes of a transparent material. The panes are typically environmentally sealed to prevent the formation of condensation between the panes, which obscures viewing through the panes. The frame typically is provided in two portions, each portion being assembled to openings formed in opposed door or wall panels, the two portions being drawn together by fasteners. Unfortunately, the frame adds significant expense to the viewport construction.
- What is needed is a frameless viewport that can be easily installed between opposed door or wall panels.
- The present invention relates to a viewport for a door or wall including substantially aligned openings disposed in inner and outer panels of a door or wall. A pane assembly is configured to permit viewing therethrough, the pane assembly being secured into position between the inner and outer panels in alignment with the openings. An injected insulating material is disposed between the inner and outer panels and around the pane assembly to substantially fill an open space between the inner and outer panels, the insulating material being configured and disposed to maintain the secured position of the pane assembly.
- The present invention further relates to a viewport for an air handling unit including substantially aligned openings disposed in inner and outer panels of a door or wall of an air handling unit. A pane assembly is configured to permit viewing therethrough, the pane assembly being secured into position between the inner and outer panels in alignment with the openings. An injected insulating material is disposed between the inner and outer panels and around the pane assembly to substantially fill an open space between the inner and outer panels, the insulating material being configured and disposed to maintain the secured position of the pane assembly.
- The present invention still further relates to a method for installing a viewport. The method includes providing inner and outer panels of a door or wall, and securing a pane assembly into position between the inner and outer panels in alignment with the openings, the pane assembly configured to permit viewing therethrough. The method also includes disposing injected insulating material between the inner and outer panels to substantially fill an open space between the inner and outer panels, the insulating material being configured and disposed to maintain the secured position of the pane assembly.
- An advantage of the present invention is that it is inexpensive to fabricate.
- A further advantage of the present invention is that it requires fewer parts.
- A still further advantage of the present invention is that it has a compact construction.
- Other features and advantages of the present invention will be apparent from the following more detailed description of the preferred embodiment, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.

- One embodiment of a
viewport 10 is shown inFIGS. 1 and 2 . Preferably,viewport 10 is used with an air handling unit (not shown), theview port 10 being formed in a wall or an access door of the air handling unit. Anopening 14 is formed in apanel 12 and anopening 18 is formed in apanel 16, theopenings panels pane 22 of a substantially transparent material having suitable optical, strength and thermal insulative properties, sized slightly larger than theopenings panels openings pane 22 to span the distance between thepanels spacer 24 is interposed between one side ofpane 22 andpanel 12, as shown inFIG. 1 . The combination ofpane 22 andspacer 24 defines a pane subassembly 20. Preferably, atape 32 having opposed adhesive surfaces is applied along the periphery of opening 18 on aninner surface 30 ofpanel 16 to secure thepane 22 to thepanel 16 and along the periphery of opening 14 on aninner surface 40 ofpanel 12 to secure thespacer 24 to thepanel 12. Alternately,tape 32 can be first applied to thepane 22 and to thespacer 24, or portions oftape 32 can first be applied topanel tape 32 is applied is not important. Upon installation of thepane assembly 20 betweenpanels FIG. 2 , insulating material (not shown), such as a polyurethane foam, is injected between thepanels - Referring to
FIGS. 1 and 3 ,spacer 24 preferably includes a plurality ofinterconnected legs 25 substantially corresponding to the periphery ofpane 22 along asurface 38. Eachleg 25 includes aweb 26 that extends at opposite ends preferably transverse to theweb 26 to formflanges 28. The profile of theweb 26 andflanges 28 of eachleg 25 defines a C-section. Preferably, theflanges 28 of one side of thelegs 25abut surface 38 of thepane 22 and theflanges 28 of the other side of theleg 25abut surface 40 ofpanel 12. If required, as shown inFIG. 3 , an application oftape 32 having opposed adhesive surfaces can be applied along the periphery of opening 14 alongsurface 40 ofpanel 12 to securepanel 12 to theflanges 28 ofspacer 24. Similarly, the surface ofpane 22opposite spacer 24abuts surface 30 ofpanel 16. If required, as shown inFIG. 3 , an application oftape 32 having opposed adhesive surfaces can be applied along the periphery of opening 18 alongsurface 30 ofpanel 16 to securepanel 16 to pane 22. Once the pane subassembly 20 has been installed, the junctures between thepanels pane 22 and thespacer 26, which junctures are enhanced if required by adhesives, such as contained intape 32, are substantially fluid tight to prevent the flow of insulating material injected between thepanels - Referring to
FIGS. 4-7 , an alternate embodiment ofviewport 110 is provided which is substantially similar toviewport 10, exceptpane subassembly 120 is substituted for pane subassembly 20. Pane subassembly 120 preferably includes a plurality ofpanes 22, eachadjacent pane 22 being separated by agasket 34.Gasket 34 preferably defines a closed, contiguous geometric shape that abuts opposed surfaces of adjacent panes along their respective peripheries to provide a fluid tight seal therebetween without visually obscuring the view through thepanes 22 once assembled. In a preferred embodiment,gaskets 34 will incorporate a desiccant to absorb moisture that could otherwise form on the inaccessible surfaces ofadjacent panes 22. In the embodiment shown inFIG. 6 , which is a partial elevation view of the assembled pane subassembly 120, the edges of thegaskets 34 andpanes 22 are substantially aligned. However, in an alternate construction, such as shown inFIG. 7 , asingle gasket 134 can extend around the periphery of a panel 122 that is betweenouter panels 222. Panel 122 is thus concealed when viewed from the side of the assembled panel subassembly 120. Although panel 122 is shown as being smaller thanpanels 222, it is to be understood thatpanels 122, 222 can have the same outside dimensions. It is also to be understood that a combination ofgaskets - Preferably,
gasket 134 does not extend around the periphery of theouter panels 222, as such a construction requires that thegasket 134abuts surfaces respective panels gasket 134 is contemplated by the present invention, so long as there is substantially no flow of injected insulating material betweengasket 134 andpanels - One skilled in the art can appreciate that the number of panes can exceed three, and that one or
more spacers 24 can be used with panel subassembly 20, 120. Further, whiletape 32 can be interposed between the junctures of any combination of panels, panes, gaskets and spacers, such tape may not be required if the junctures are sufficiently fluid tight to substantially prevent the flow of injected insulating material therebetween and thepanel subassembly - It is to be understood that the panel openings and corresponding panes and gaskets can have any closed geometric shape.
- While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
