Abstract

A frameless glass door arrangement for a doorway bounded in part by a top section and a bottom section is disclosed. The frameless glass door arrangement includes two hinge parts rotatably embedded in the respective top section and bottom section; and a glass door leaf including a main body including a top edge, a bottom edge and a lateral edge, the glass door leaf further including two tongue-shaped extensions disposed adjacent to the lateral edge. The extensions extend outward from the respective top edge and bottom edge of the main body and into the respective hinge parts so that the doorway is completely transparent after the glass door leaf is installed in the doorway.

Claims (10)

1. A frameless glass door arrangement for a doorway bounded in part by a top section and a bottom section each having a predetermined contour, the frameless glass door arrangement comprising:

two hinge parts rotatably embedded in the respective top section and bottom section; and

a glass door leaf comprising:

a main body comprising a top edge, a bottom edge and a lateral edge, the top and bottom edges of the main body having the respective predetermined contours of the top and bottom doorway sections; and

two tongue-shaped extensions disposed adjacent to the lateral edge,

wherein the extensions extend outward from the respective top edge and bottom edge of the main body and into the respective hinge parts so that the entire doorway provides an unobstructed view when the glass door leaf is in a closed position in the doorway, and the main body and the extensions are integrally formed as a single piece of material.

2. The frameless glass door arrangement of claim 1 , wherein the extensions are bonded to the respective hinge parts.

3. The frameless glass door arrangement of claim 2 , further comprising a door closer embedded in one of the top section and the bottom section and comprising a pin, a respective hinge part being mounted on the pin.

4. The frameless glass door arrangement of claim 2 , further comprising threaded spindles engaging the door closer, the door closer being movable away from the glass door leaf so that the respective hinge part can be disengaged from the pin to allow the glass door leaf to be removed from the doorway.

5. The frameless glass door arrangement of claim 1 , further comprising two bearing shells non-rotatably embedded in the respective top section and bottom section, the hinge parts being seated in the respective bearing shells, at least one of the bearing shells being movable away from the glass door leaf so that the respective hinge part can be disengaged from the at least one of the bearing shells to allow the glass door leaf to be removed from the doorway.
