This invention relates generally to roll-type retractable door screens. More particularly, this invention relates to a door frame assembly incorporating a door and a roll-type retractable screen.
Entryways into residences and recreational vehicles (“RVs”) often include a main, solid door and a screen door. In commercial and residential buildings, the screen doors often swing outwardly while the main, solid door swings inwardly. On the other hand, the door arrangements on RVs are usually opposite that of buildings. In RVs, both doors are generally hinged to swing outwardly because of the lack of space within the RV for either of the doors to swing inwardly. The lack of space in RVs usually is due to RV designs that attempt to maximize the interior space by placing the steps and other functional structures immediately inside the entryway of the RV. These steps and structures often inhibit the range of motion of any door and thus the ability to swing inwardly.
Screen doors are often essential on RVs, as many RV exterior doors contain only small windows. Including a screen in the windows is thus often ineffective for promoting air circulation. To enable adequate air circulation, the exterior doors can be swung outwardly and latched in an open position. However, opening the exterior door without including a screen barrier can provide access into the interior of the RV for insects and pests. Thus, including screen doors on RVs can provide a barrier to insects and pests while enabling adequate air circulation within the RV.
However, while current RV screen doors can provide a barrier to insects and pests and enable air circulation, there are particular problems and deficiencies inherent with conventional RV screen door designs. For example, the screen door and exterior door often include complex latches and hinges required to enable both doors to swing outwardly at the same time and also be separately swingable to enable the screen door to be closed while the exterior door remains open. Additionally, conventional RV screen doors also often contain complex cross rails and openings with sliding screen panels to enable the user to unlatch the exterior door from the inside of the RV. These cross rails and panels can obstruct the view through the screen door and make unpleasant rattling noises when the screen door is opened and closed.
There are currently commercially available retractable screen doors, such as those made and sold by Phantom Mfg. (Int'l) Ltd., which have been installed on RVs. These screen doors are attached separately with respect to existing RV doors and the doorframe. As such, when installed, the tracking and frame structures require additional interior or exterior space and substantial installation. When exteriorly installed, these doors stick out beyond the opening or entry of the RV creating undesirable aesthetics and structural functionality for the RV. Installing the Phantom screen also requires drilling into the interior or exterior of the RV, which can damage the RV.
Another problem inherent with screen doors, such as those made and sold by Phantom Mfg. (Int'l) Ltd., is that a connector portion of the screen slides along an exterior/outer ledge of the window frame or track. In these attempts, however, the connector portion must be shorter than the screen and screen cassette to allow room for the ledge connection. This configuration leaves the edges of the screen unattached to the pull rail, thus imparting a non-uniform stress force on the screen, potentially damaging the screen. Manufacturing costs and efforts are, therefore, not ideal.
As a result, there is a need for a door assembly that addresses the innate deficiencies present with conventional door and screen designs.
The RV door retractable screen assembly of the various embodiments of the present invention substantially solves the problems of conventional RV doors by providing a door assembly having a master frame, a main or primary door, and a retractable screen, each contained on or in the frame that can be easily and quickly installed into a building or a recreational vehicle. The frame can be easily installed into a RV during manufacture or fitted onto an existing RV opening or entry area. As such, a screen door is provided that can operate independently from the exterior door and inhibit insect entry into the interior of the RV.
A feature and advantage of a door assembly of the various embodiments of the present invention is that a master frame operably carries a door and screen assembly, as well as the tracking for slidably receiving the screen edges and a pull bar during use.

The cassette or roll 142 is generally disposed within the cassette housing 136 and is operably coupled to first and second cassette projections 148, 150 disposed on the first and second cassette end caps 138, 140, respectively. The bushing assemblies 144, 146 enable the cassette 142 to rotate with respect to the first and second cassette projections 148, 150 disposed on the first and second cassette end caps 138, 140. The cassette 142 is generally disposed within the cassette housing 136 and is operably coupled to first and second cassette projections 148, 150 with the first and second bushings assemblies 144, 146, respectively.
The cassette assembly 132 can also include a spring mechanism, for retracting or rollably wrapping the screen 95 onto the cassette 142. An end portion of the screen 94 distal the pull bar 134 is operably connected to the cassette 142. In one embodiment, the screen 95 is under a biasing retracting force upon sliding extraction from the cassette 142 along the tracks 92, 116. While such a mechanism could include a spring or motor, these examples are not limiting and other mechanisms could be used without departing from the scope of the present invention. The cassette housing 136 and cassette 142, and the end caps 138, 140, can be constructed of various known materials.
As stated above, the screen assembly 46 further includes the screen panel 95 and the pull bar 134. The pull bar 134 can include glides or shoes 135, or other guiding structures that are configured to operably couple or guide the pull bar 134 and screen 95 along the top and bottom tracks 92, 116 while opening and closing the screen assembly 46, as shown in
The pull bar 134 can include handle or latch/catch portions, disposed thereon for manually opening and closing of the retractable screen assembly 46. The pull bar 134 can also include a magnet configured to include a magnet for mating with a magnet, or metal component, included on the second jamb 50 to retain the screen 95 in the closed position.
To install the door assembly 40 into an opening of a building or RV for one embodiment, the master frame 42, including the main door 44, is inserted in the opening. In particular, the master frame 42 without the screen assembly 46 or the members 80, 104 can be placed into and secured to an opening on a RV such that the sill 62 rests on a bottom portion of the opening, and the door abuts the RV frame structure. The screen assembly 46 is then installed on the interior of the master frame 42, with the cassette housing 136 being inserted into the recess 120. Further, members 104, 80 can be attached to the interior portion of the header portion 52 and the second jamb 50 at this point to complete installation of the master frame 42 components. As such, component maintenance, replacement and adjustment is permitted. The nature of the door assembly 40 according to the various embodiments of the present invention enables the installation of the door assembly 40 to be completed with minimal steps. This can save installation time and money and prevent improper installation.
In an embodiment, the RV or door assembly 40 can include one or more insulation or sealing members between the faces 68, 77, 88, or other assembly 40 components, and the RV structure. In such an embodiment, the assembly 40 components or surfaces would not necessarily directly abut the RV walls or structures, but would rather sandwich the insulation or sealing members therebetween.
In another embodiment, the sill 62 is first installed onto a lower edge of an opening included on a RV. The door assembly 40, including a master frame 42 having first and second jambs 48, 50 and a header 52 is installed proximate the pre-installed sill 62 as previously described. The door assembly 40 is then operably attached to the sill 62 and/or RV. Various other installation steps or configurations are envisioned as well.
Once the door assembly 40 has been installed into a RV, the door 44 and screen assembly 46 can be selectively opened and closed independently of each other. The door 44 can be selectively opened and closed by moving the door 44 about the one or more hinges 121. The retractable or rollable screen 95 and/or bar 134 can be selectively opened and closed by being slid or otherwise moved along the first and second tracks 92, 116 included on the header 52 and sill 62, respectively. In an embodiment of the present invention, the screen 95 selectively retracts between an open position and a closed position within the frame interior defined by the first and second jambs 48, 50, header 52, and sill 62.
The screen 95 can be moved or slid to an open position wherein the screen panel 95 is substantially wound upon the cassette or roller 142 and the pull bar 134 is at a position proximate the cassette housing 132. In various embodiments, the screen 95 is under a biasing retracting force from the roller 142, thus applying a biasing force on the screen 95 toward the roller 142. Referring to
