BACKGROUND OF THE INVENTION

This invention relates to the design for the manufacture of sliding glass doors that are used in building, including but not limited to private homes, apartments and commercial building.

Currently, sliding glass doors are manufactured with one half of the door fixed (the outside panel) and one half of the door (inside panel) sliding. There is a choice for a door that opens either right to left or left to right. The choice must be made prior to installation and once chosen, the door is installed to permanently open right to left or left to right. If the opposite opening is desired; the sliding glass door must replaced. This invention provides the design to allow the doorway opening right to left to change to a doorway opening left to right at anytime. This ability to change the access to a room will allow greater flexibility in furniture or equipment arrangements in the room.

BRIEF SUMMARY OF THE INVENTION

The sliding door frame has three tracks, one for the outside panel and one for the inside (door) panel and one on the outside for a screen door. The outside panel can slide to either side of the opening and lock into place. The inside panel can slide from either end of the door frame to open and close for door access to the room or building. The screen door can slide to either end of the opening.

DETAILED DESCRIPTION OF THE INVENTION

The sliding glass door 10 is comprised of a frame 14 with door tracks 18 that hold two door panels, an outer door panel 24a and an inner door panel 24b, each covering half of the opening, there is an additional outside track 26 for the sliding screen door 28 (see FIGS. 2A and 2B).

The outer panel 24a slides on the outside track 18b and locks in place at either end of the opening to provide the security and support of the fixed portion of the sliding glass door assembly. The panel locks to the door frame on the top, bottom and side. The top and bottom track locks 34 can be either deadbolt type locks or clamp type locks (not shown) as would be dictated by the construction material. For example, a deadbolt type lock may work better in a door manufactured in wood, a clamp type lock may work better in an aluminum door. The lock assemble is flush with the inside surface of the panel so as not to obstruct the sliding of the inside door panel. The lock on the side 38 of the panel clamps or hooks to the frame to the secure the panel in position. The locks are the same on each side of the door frame 14.

FIGS. 3A and 3B depict the manner in which the sliding glass door of the present invention may be selectively configured to change on which side: right or left, the sliding doorway opens. In FIG. 3A the outer door panel 24a is positioned adjacent the right side of the sliding glass door frame 14 and locked in position using track locks 34 (only one shown). The inside panel slides within the inner track 18a, from a locked position in the left door frame to an open position adjacent the right side of the frame 14. The access doorway is thus located at the left side of the sliding glass door (from a position looking out, through the door). In FIG. 3B the outer door panel 24b has been positioned to the left side of the sliding glass door frame 14, and the access doorway is now located at the right side of the sliding glass door (again, if looking out through the door).

As is best shown in FIG. 4, inserts cover the outside track 18b to provide a finished, level surface for the open half of the door frame and also add to the security of the “fixed” portion of the sliding glass door. The insert consists of four (4) sections that may be separate pieces or connected. The section insert into the top 44, side 46 and bottom 48 track opening (sections 1-3). The insert for sections 1-3 is U-shaped to fit inside and fill the tract. Section 4 is a U-shaped cap 52 that fits over the exposed end of the outer panel 24a. On the inside of the U there is a latch that the locks with the lock on the side of the panel 24a. When the cap 52 is on the end of the panel 24a, it overlaps the end of the insert for the top and bottom track inserts 44, 48. The lock on the sides of the panel latch to the door frame 14 on one side and lock to the insert 52 on the other side, depending on the right or left opening that is chosen (also shown in FIG. 6).

In FIGS. 5A and 5B the inside panel 24b, the sliding glass door, slides on the inside track. On the inside, the sliding glass door 24b has a handle and lock assembly 58 on both sides. The handles (not shown) on the outside of the inside door panel 24b are indented for a flush surface on the outside of the panel to allow the inside door panel 24b to slide past the outside panel 24a. When the door opens right to left as shown in FIGS. 4A and 4B); the handle 58 on the right, locks to the door frame to lock the door closed; and the handle on the left locks onto a door end cap 66 for the end of the door panel 24b (see FIGS. 6A and 6B). When the door opens left to right; the handle on the left, locks to the door frame to lock the door closed; and the handle on the right locks onto the door end cap 66 for the end of the door panel.

The door end cap 66 for the end of the panel is reversible to provide a finished edge to the exposed end of the door. The cap extends to the end of the door the same distance that the door closes into the door frame to close and seal. The weather strip that is on the inside of the door that seals it when closed into the door frame, also seals into the cap.
