## Abstract

A windowed door is provided with an internal compartment accommodating a window pane having an area at least twice that of the window aperture. The compartment and aperture are eccentrically disposed with respect to one another such that a portion of the pane not previously exposed through the aperture is exposed when the pane is reversed in the compartment.

## Claims

### Claim 1

A door comprising in combination:
a pair of similar spaced apart in parallel confronting relationship to one another so as to form an interior compartment therebetween, said compartment communicating with the exterior of said door through an edge of the door;
a pane of transparent material shaped and dimensioned to slidably fit into said compartment so that the pane may be reversed in the compartment; and
a window opening having an area less than half that of said pane in each of said panels, said openings being in line with one another and and a portion of said pane so as to permit vision therethrough and further being aligned eccentrically with regard to said compartment so as to conceal a symmetrically disposed similar portion of said pane.

### Claim 2

A door comprising in combination:
a plurality of substantially rectangular panels;
means for holding said panels in parallel spaced-apart confronting relationship to one another;
mutually confronting means in each panel defining a window opening having predetermined linear dimensions;
means defining a rectangular compartment between said panels, said compartment being in open communication with a selected edge of said door and having at least one linear dimension parallel an edge of said door at least twice as large as a corresponding dimension of said window opening, said window opening and said rectangular compartment being dispoed relative to one another so that said window opening is opposite and opens into said compartment with at least a symmetrically disposed similar portion of said compartment not opposite said window opening; and
a rectangular pane of transparent material shaped and dimensioned to slidably fit into said compartment.

### Claim 3 (depends on 2)

The door according to claim 2 wherein said symmetrically disposed similar portion of said compartment comprises at least a contiguous half of said corresponding dimension of said compartment.

### Claim 4 (depends on 2)

The door according to claim 2 wherein said means for holding is a U-shaped solid core.

### Claim 5 (depends on 2)

The door according to claim 2 wherein said means for holding is a rectangular frame peripherally disposed about said panels so as to define an open interior space between said panels, said assembly further incorporating framing members within said interior space, said members in part defining said compartment, and said frame further having at least a portion of an edge member removed so as to provide edge access to said compartment.

### Claim 6 (depends on 4, 5)

The door according to claim 4 or 5 wherein said selected edge is a vertical edge.

### Claim 7 (depends on 2)

The door according to claim 2 further including a plug for closing said compartment at said selected edge.

### Claim 8 (depends on 7)

The door according to claim 7 wherein said selected edge is the hinged edge of said door.

### Claim 9 (depends on 4, 5)

The door according to claim 4 or 5 wherein said selected edge is a horizontal edge.

### Claim 10 (depends on 9)

The door according to claim 9 wherein said horizontal edge is the top edge.
