## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This document claims the benefit of the filing date of U.S. Provisional Patent Application 61/590,105, entitled “SELF-SECURING SCREEN DOOR ASSEMBLY” to John Ewoldt which was filed on Jan. 24, 2012, the contents of which are hereby incorporated by reference.


BACKGROUND
1. Technical Field
Aspects of this document relate generally to security door assemblies.
2. Background Art
Security doors are a common feature in many homes, providing either an added measure of security to a traditional door or a secure door even when the traditional door is open. Various varieties and models of security or storm doors are presently available to consumers. Many security or storm doors, however, have drawbacks in functionality or utilization by the consumer. For example, handle placement may injure a user's hands, fasteners may not secure the glass to door frame, or poorly designed nylon pins may fail to properly hold the glass panel within the frame. Each of these shortcomings and various others prevent the long-term functionality of the self-storage glass door, while increasing the risk of user injury.

DESCRIPTION
This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended security doors and/or assembly procedures for a security door will become apparent for use with implementations of a door frame and single track framing unit from this disclosure. Accordingly, for example, although particular glass sections, screen sections, tracks, side members, counter balance springs, stop elements, latching elements is disclosed, such elements and implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such door assemblies and implementing components, consistent with the intended operation of a door assembly.
The utilization of a self-storing security door assembly as described herein has numerous advantages over the prior art. Any reference to dimensions in either the figures or the description is for exemplary purposes only, and not used for limitation. As shown in FIG. 1, an implementation of a self-storage glass or security door assembly may comprise a main door frame 100 divided into at least a first portion 108 and a second portion 110.
As shall be described in greater detail in this document, a self-storing door assembly may comprise a reversible door. In an embodiment, the main door frame 100 may be rotated 180 degrees from top to bottom to reverse the side of the door frame to which the handle 140 and the hinges 104 couple. For example, in an upright position, the door assembly may comprise the hinges 104 on the left side of the door frame 100, the handle 140 on the right side of the door, the first portion 108 of the main door frame 100 on the top, and the second portion 100 of the main door frame 100 on the bottom. If desired, a user may rotate the door 180 degrees, such that the handle 140 is on the left side of the door frame 100, the hinges 104 are on the right side of the door frame 100, the first portion 108 of the door frame 100 is on the top, and the second portion of the door frame 100 is on the bottom.
In cooperation with this reversibility feature, the various sections of material may be fixedly coupled to the first 108 and second 110 portions of the main door frame 100. For example, a user may fixedly couple a first glass section 132 to the first portion 108 of the main door frame 100 and a screen section 130 to the second portion 110 of the main door frame 100. If the main door frame 100 is rotated, the user may fixedly alternate the glass section 132 and the screen section 130. The glass section 132 may comprise any type of glass, such as but not limited to tempered stamp embossed glass. In other words, the glass 132 and screen 130 sections are each symmetrically fabricated to be interchangeable in the main door frame 100.
One or more embodiments of the door frame 100 comprise a plurality of side members 102, an example of which is shown in FIG. 1. In FIG. 1, the door frame comprises four side members 102 coupled together to form a substantially rectangular door frame 100. The main door frame may further comprise a freeze bar 106 coupled to opposing side members 102 and separating the first portion 108 of the door frame 100 from the second portion 110 of the main door frame 100. The first portion 108 and the second portion 110 are each typically holes or openings that extend all the way through the main door frame 100. As shall be shown and described in greater detail in subsequent figures, some embodiments of the main door frame 100 further comprise a recessed track 112 on the interior edge 114 of either or both the first half and the second half. The recessed track 112 may be configured such that when the glass section 132 or the screen section 130 is placed within the recessed track 112, the edges of the glass section 132 or screen section 130 are substantially level with or below the planar surface of the side members 102 of door frame 100. In other words, the glass 132 and screen sections 130 are recessed into the side members 102 of door frame 100.
FIG. 9 illustrates an exploded view of an embodiment of a door frame 100. As previously described, the door frame 100 comprises a plurality of side members 102 and a freeze bar 106 extending between two opposing side members 102 and separating the first portion 108 from the second portion 110. A first glass section 132 and a screen section 130 are shown away from the first 108 and second 110 portions prior to coupling. FIG. 9 also illustrates a plurality of handle holes 171 that extend through one of the side members 202. The handle holes 171 are positioned to allow for easy coupling of a handle 140 to the door frame 100.
FIG. 13 illustrates an exploded view of an embodiment of a self-storing security door assembly, included the main door frame 100, the self-storing glass sub assembly 200, the screen section 130, the first glass section 132, the second glass section 134, the hinges 104, as well as other self-storing security door assembly components, such as but not limited to a jamb, a jamb latch, jamb hinges, a bug sweep, and a bug screen insert.
FIG. 2 illustrates a partial cross-sectioned of a portion of the door assembly taken at line 2 of FIG. 1. As shown in the exemplary embodiment of FIG. 2, the door assembly may comprise the side member 102 of the door frame 100, the screen section 130 (or alternatively the glass section 132), and a sliding second glass section 132. FIG. 2 further illustrates one exemplary embodiment of the recessed track 112 of the main frame 100. The recess may allow the fixed glass 132 or screen sections 130 to sit below the surface level of the door frame 100. In the exemplary embodiment shown in FIG. 2, the recessed track 112 comprises two substantially perpendicular planar surfaces. One of the planar surfaces of the recessed track 112 is typically substantially perpendicular to the interior edge 114 of the respective side member 102, while the other planar surface is typically substantially perpendicular to the facial surface of the side member 102. In other alternative embodiments, however, the recessed track 112 may comprise any suitable configuration that allows the glass 132 and screen 130 sections to couple to the door frame 100 with the recessed tracks 112.
In one or more embodiments, as exemplified in FIG. 2, a recessed track 112 allows for the attachment or coupling of a self-storing glass sub-assembly 200 to the main door frame 100. Embodiments of the self-storing glass sub-assembly 200 are typically configured to be coupled to the door frame 100 over or in front of the recessed tracks 112 of the door frame 100. The self-storing glass sub-assembly 200 may comprise a self-contained unit capable of comprising any of or at least the following features: a single track aluminum frame comprising one or more protruding tracks 120 and one or more track side members 124, a counter spring 123 loaded inside a balance mechanism, a hand hold element 149, a latching mechanism, a safety stop 155, and/or corner keys 144.
One or more embodiments of the protruding track 120, such as that shown in FIG. 2, comprise a first channel 122. Each first channel 122 is typically sized to allow a portion of the slidable glass section 134 to fit and slide therein. Moreover, embodiments of the protruding tracks may also be configured to form, in combination with the recessed track 112 of the side members 102, a second channel 116 when the protruding track 120 is coupled over the recessed track 112. In such embodiments, a portion the fixed first glass section 132 and the fixed screen section 130 fit are fixedly or removably coupled within the second channel 116. When within the second channel 116, the screen section 130 and the first glass section 132 are typically below the plane of the facial surface of the side member 102.
In some embodiments, the self-storing glass sub-assembly 200 allows for a moveable or slidable second glass section 134 to be slid up and down within the protruding tracks 120 from the first portion 108 of the door frame to the second portion 110 of the door frame 100, or from the second 110 of the door frame 100 to the first portion 108 of the door frame 100. Such movement enables a user to cover either the fixed screen section 130 or fixed glass section 132, or portions of both the fixed screen section 130 and the fixed glass section 130.
Embodiments of a self-storing glass sub-assembly 200 are removably coupled to door frame 100 with one or more screws 198. The self-storing glass sub-assembly 200 and the door frame 100 typically comprise one or screw holes 100 positioned to align when both before and after 180° rotation of the self-storing glass sub-assembly 200. When screw holes 199 are aligned, one or more screws 198 couple the self-storing glass sub-assembly 200 to the door frame 100.
FIG. 11 illustrates an exploded view of an embodiment of a self-storing glass sub-assembly. In one or more embodiments, each track side member 125 may couple to one or more protruding tracks 120. A corner key 142, as previously described, may provide support at each corner for the track side members 125 and the protruding tracks 120. FIG. 12 illustrates an exploded view of an exemplary self-storing glass sub-assembly.
One example of a self-storing glass sub-assembly 200 is shown in FIG. 6. Embodiments of the self-storing glass sub-assembly 200 may comprise opposing protruding track 120 members and opposing track side members 124, 125. Embodiments of the track side members 124, 125 and the protruding tracks 120 are described elsewhere in this document. Movement of the movable glass section 134 may be enhanced or facilitated by the counter balance spring 123 loaded inside a balance mechanism contained within the self-storing glass sub-assembly 200. In one or more embodiments, the counter balance spring 123 is positioned within or proximate the first channel 122 and configured such that moveable glass section 134 may rest or stop at any point along the self-storing glass sub-assembly 200.
For example, a user may move the movable glass section 134 to partly cover the first glass section 132 (or first portion 108 of the door frame 100) and partly cover the screen section 132 (or second portion 110 of the door frame 100), as shown in FIG. 8. When released in this position, the counter balanced moveable glass section 134 remains in this position without the assistance of any other locking or latching elements. Likewise, the counter balance allows the moveable glass section 134 to be moved anywhere along the self-storing glass sub-assembly 200 and remain in that position when released without the assistance of any other locking or latching elements. In FIG. 6, the moveable glass section 134 is positioned adjacent one of the two track side members 125.
The self-storing glass sub-assembly 200 may further comprise a latching element 159 (shown in FIGS. 12 and 14) that temporarily couples the movable glass section 134 to the self-storing glass sub-assembly 200 at the top of the single track framing unit 200. Such a temporary coupling secures the movable glass section 134 in a raised position, thus completely or substantially covering the fixed screen section 130 if the screen section 130 is coupled above the fixed glass section 132. The latching element 159 may comprise any element that allows the movable glass section 134 to be removably coupled to the top section of the single track framing unit 200. In other embodiments, a latching element 159 may be located between the first 108 and second 110 portions of the door frame 100, or rather between the fixed screen section 130 and the fixed glass section 132. In such an embodiment, the latching element 159 may likewise hold the movable glass section 134 in the upper position, providing additional support to hold the movable glass section 134 in place.
FIG. 10 illustrates an exploded view of an exemplary sliding glass assembly that includes the second glass section 134. In one or more embodiments, the sliding glass assembly may comprise side members 220 and weather strips 230 that couple to the second glass section 134. In some embodiments, the hand hold element 149 extends from a side member 220.
The self-storing glass sub-assembly 200 may further comprise a hand hold element 149. The hand hold 149 may comprise any element that allows a user to more easily grasp or grip the movable glass section 134 to move the movable glass section 134 to various positions along the self-storing glass sub-assembly 200. In particular embodiments, the hand hold 149 unit is a fin extending perpendicularly from and coupled to or part of a frame around the moveable glass section 134.
FIG. 3 illustrates a partial cross-sectioned view of an embodiment of a self-storing security door assembly taken along line 3 of FIG. 1 and showing the bottom portion and the top portion thereof. Embodiments of the self-storing glass sub-assembly 200 further comprise two opposing track side members 124 each coupled to opposing protruding tracks 120. Although the track side members 124 shown in FIG. 3 comprise a substantially planar protrusion that extends outward from the door frame 100, other embodiments of the track side members comprise a first channel 122 similar to that described in relation to the first channel 116 of the protruding track 120.
FIG. 4 illustrates a partial cross-sectioned view of the handle area of the self-storing security door assembly taken along line 4 of FIG. 1. In this and other embodiments, the self-storing security door assembly is improved over previous door assemblies due to the low profile nature of the fixed and movable sections of the door assemblies. By coupling the fixed sections 130, 132 of the door assembly within the recessed track 112 of the door frame 100 and providing a slim or low profile self-storing glass sub-assembly 200 over the fixed sections, more room is present between the door handle 140 and the movable glass section 134. Due to the positioning of the cross-sectioning shown in FIG. 4, neither the fixed first glass section 132 nor the fixed screen section 130 is visible.
Furthermore, the handle 140 of the self-storing security door assembly may also be configured to be reversible. For example, a user may remove the handle 140 and locking element of the door frame 100, rotate, and then reinsert them into the door frame 100 to adapt for a reversed door opening.
FIG. 5 illustrates an embodiment of a corner key 142, and FIG. 7 illustrates an embodiment of a corner key 142 partially in use with a single track framing unit 200. In one or more embodiments, a corner key 142 may comprise two coupling elements 144 coupled together at a corner. In particular embodiments, corner key 142 is substantially planar, while in other embodiments, similar to the embodiment shown in FIG. 5, the two coupling elements 144 are angled from one another. Particular embodiments include one or more walls that protrude from the coupling elements opposite the substantially perpendicular angle formed by the intersection of the two coupling elements 144. Some embodiments comprising the walls that protrude from the back side of the coupling elements may comprise rounded walls configured to complement or otherwise mate with openings on the track side member 125 or protruding track 120. The corner key 142 may comprise similar or different sizes, edges, tips, and the like. In an embodiment, one coupling element 144 may be shorter or smaller than the second coupling element 144. In this or other embodiments, one coupling element 144 may comprise squared edges, while the other coupling element 144 comprises rounded edges.
As shown in one exemplary embodiment in FIG. 7, the corner key 142 may be sized to fit within the self-storing glass sub-assembly 200, each one of the two coupling elements 144 fitting into a separate piece (protruding track 120 or track side member 125) of the self-storing glass sub-assembly 200. In embodiments similar to that shown in FIG. 7, one coupling element 144 is inserted into an embodiment of a track side member 125, and the other coupling element is inserted into the protruding track 120. Embodiments of the track side member 125 and the protruding track 120 may further comprise an inward track, ridge or guide 145 the more firmly secures the coupling element 144 within the respective track side member or protruding track 120.
Once inserted, the corner key 142 holds two pieces of the single track unit together in a substantially perpendicular and stable angle. In a particular embodiment, a corner key is utilized at each of the four corners of an assembly self-storing glass sub-assembly 200, coupling one protruding track 120 to one track side member 125. The corner key 142 aids in the reversibility feature of the door assembly and may comprise any element that assists in holding the tracks together at the intersection of vertical and horizontal pieces of the self-storing glass sub-assembly 200. For example, if a user has the need to rotate the door assembly (to move the handle 140 and hinges 104 to opposite sides, as previously described), the user may remove the self-storing glass sub-assembly 200 from the main door frame 100. The corner keys 142 allow the self-storing glass sub-assembly 200 to stably remain together, even after the self-storing glass sub-assembly 200 is removed from the main door frame 100. Without the corner keys, the flimsy nature of the aluminum (of an exemplary embodiments) self-storing glass sub-assembly 200 may result in an unstable framing unit easily susceptible to bending and breaking once removed from the main frame 100.
FIG. 7 further illustrates an embodiment of a safety stop 155 that may be coupled or mounted on a self-storing glass sub-assembly 200. The safety stop 155 may be positioned proximate the top, the bottom, or both the top and the bottom of the self-storing glass sub-assembly 200. In some embodiments, the safety stop 155 fits within the first channel 122 of the protruding track 120, while in other embodiments the safety stop is coupled to or extends from the track side member(s) 124, 125. The safety stop 155 may comprise any configuration that prevents the sliding second glass section 134 from sliding out of or beyond the first channels 122 of the protruding tracks. Alternatively or additionally, the safety stop 155 may comprise any configuration that provides a softer surface 153 that prevents the sliding second glass section 134 from breaking if the sliding second glass section slams against the top or the bottom of the self-storing glass sub-assembly 200. The safety stop 155 may further prevent the sliding second glass section 134 from pinching a user's fingers between the self-storing glass sub-assembly 200 and the movable glass section 134. The safety stop 155 may comprise any element that prevents the movable glass section from contacting the bottom of the single track framing unit, such as but not limited to a ridge in the first channel 122, and additional piece inserted into the first channel 122, a limit near the bottom of the track, and the like.
