Abstract

The invention provides a screen door system for double-hung entry doors. The screen door system comprises an inner screen assembly containing a frame member carrying a screen member, an outer screen assembly containing a frame member carrying a screen member, inner and outer upper tracks for slidably guiding the inner and outer screen assemblies along the length of the tracks and for limiting lateral movement of the inner and outer screen assemblies as the screen assemblies move longitudinally along the tracks, and a lower sill having an inner guide rail for longitudinally guiding the inner screen assembly and an outer guide rail for longitudinally guiding the outer screen assembly.

Claims

1. A door assembly comprising:

a first and a second hinged entry door, said hinged entry doors being substantially coplanar when in a closed position, said first hinged entry door further having an outwardly projecting handle,

an inner and an outer screen door, said inner screen door having a height which is less than that of the outer screen door, and

a track assembly for slidably guiding said inner and outer screen doors, said track assembly comprising a threshold baseplate for attachment to a doorway threshold,

inner and outer spaced apart substantially parallel, upstanding tracks connected to the baseplate for engagably supporting the inner and outer screen doors, respectively, which tracks traverse substantially the entire length of the baseplate, said inner track further being vertically offset above the outer track to accommodate the height of the inner screen door and

a threshold attachment means, wherein the spaced apart tracks are positioned on the baseplate such that when the baseplate is attached to the threshold using the threshold attachment means, the inner screen door supported on the inner track is spaced from the door sufficiently to enable at least one screen door to clear the door handle when the screen door is slid along the track.

2. The door assembly of claim 1 wherein the attachment means comprises one or more apertures in the assembly for fixedly attaching the assembly to a doorway threshold using a screw or nail through the one or more apertures.

3. The door assembly of claim 1 wherein the baseplate is an extruded aluminum baseplate.

4. The door assembly of claim 1 wherein the upstanding tracks are of substantially equal height from the baseplate.

5. The door assembly of claim 1 wherein the inner track is spaced from the first entry door sufficiently to enable the inner screen door to clear the door handle when the inner screen door is slid along the inner track.

6. The door assembly of claim 1 wherein the upstanding tracks contain one or more drainage apertures therein.

7. The door assembly of claim 1 wherein the inner and outer tracks are substantially the same height.

8. The door assembly of claim 1 wherein the door assembly further comprises a side frame member and the inner screen door is fixedly attached to the side frame member.

9. A door assembly comprising:

a first and a second hinged entry door, said hinged entry doors being substantially coplanar when in a closed position, said first hinged entry door further having an outwardly projecting handle,

an inner and an outer screen door, said inner screen door having a height which is less than that of the outer screen assembly, and

an upper track for slidably guiding the inner and outer screen doors, said upper track including

a first U-shaped channel having a first channel base member,

a second U-shaped channel having a second channel base member, and

a first side channel member common to said first and second U-shaped channels and attached to said first and second channel base members,

wherein said first and second base members are offset relative to one another so that the first and second base members lie in different substantially parallel planes and wherein each U-shaped channel contains a second side channel member on an opposing side of the channel base member from the first side channel member, said second side channel members having respective dimensions sufficient to limit lateral movement of the screen assemblies as the screen assemblies are moved in a direction substantially parallel to the U-shaped channels.

10. The door assembly of claim 9 wherein the door assembly further comprises a side frame member and the inner screen door is fixedly attached to the side frame member.

11. The door assembly of claim 9 further comprising an upstanding rigid elongate member substantially centered between said first and second side channel members of each channel for slidably guiding an inner and an outer screen assembly.

12. The door assembly of claim 11 wherein the upstanding rigid elongate member has a height within the range of about 0.2 to about 0.4 inches (about 0.5 to about 1.0 cm).

13. The door assembly of claim 9, said upper track having an overall width of no greater than about 2 inches (about 5 cm).

14. The door assembly of claim 9 wherein said first and second base members are offset about 0.5 inches (about 1.3 cm) or more relative to one another.

15. A door assembly comprising:

a first and a second hinged entry door, said hinged entry doors being substantially coplanar when in a closed position, said first hinged entry door further having an outwardly projecting handle,

an inner and an outer screen door, said inner screen door having a height which is less than that of the outer screen door,

a track assembly for slidably guiding said inner and outer screen doors, said track assembly comprising a threshold baseplate for attachment to a doorway threshold, a threshold attachment means, and inner and outer spaced apart substantially parallel, upstanding tracks connected to the baseplate for engagably supporting the inner and outer screen doors, respectively, which tracks traverse substantially the entire length of the baseplate, said inner track further being vertically offset above the outer track to accommodate the height of the inner screen door, wherein the spaced apart tracks are positioned on the baseplate such that when the baseplate is attached to the threshold using the threshold attachment means, the inner screen door supported on the inner track is spaced from the door sufficiently to enable at least one screen door to clear the door handle when the screen door is slid along the track, and

an upper track for slidably guiding the inner and outer screen doors, said assembly including a first U-shaped channel having a first channel base member, a second U-shaped channel having a second channel base member, and a first side channel member common to said first and second U-shaped channels and attached to said first and second channel base members, wherein said first and second base members are offset relative to one another so that the first and second base members lie in different substantially parallel planes and wherein each U-shaped channel contains a second side channel member on an opposing side of the channel base member from the first side channel member, said second side channel members having respective dimensions sufficient to limit lateral movement of the screen assemblies as the screen assemblies are moved in a direction substantially parallel to the U-shaped channels.

16. The door assembly of claim 15 wherein the door assembly further comprises a side frame member and the inner screen door is fixedly attached to the side frame member.
