Abstract
An improved door rail system for holding a panel, such as a glass panel, is presented. The door rail system includes a core rail and clamping rails having a wedging geometry so that when the clamping rails are actuated with respect to the core rail, clamping force is applied to the glass panel to secure the panel within the core rail. The improved door rail system accommodates panels of varying thickness, features the use of modular side covers and incorporates a door to door jamb adjustment device allowing for angular adjustments.
Claims41
A rail system for securing a panel, comprising:
- a core rail having a clamping channel, wherein the clamping channel is defined by mutually opposed inclined surfaces;
- two clamping rails disposed mutually opposed within the clamping channel, each clamping rail having an inclined surface which bears upon one of the mutually opposed inclined surfaces of the clamping channel, and, each clamping rail being configured to bear upon a face of a panel to be secured;
- a pulling rail disposed within the clamping channel, the pulling rail being at least partially disposed between and, in contact with, the clamping rails and supporting an edge of the panel to be secured;
- actuation hardware configured to move the two clamping rails relative to the core rail in a driven direction;
- and
- wherein the core rail includes at least one groove and at least one tongue disposed on an exterior face of the core rail, which interface with at least one tongue and at least one groove of at least one side cover.
A rail system for securing a panel, comprising:
- a core rail having a clamping channel, wherein the clamping channel is defined by mutually opposed inclined surfaces;
- two clamping rails disposed mutually opposed within the clamping channel, each clamping rail having an inclined surface which bears upon one of the mutually opposed inclined surfaces of the clamping channel, and, each clamping rail being configured to bear upon a face of a panel to be secured;
- a pulling rail disposed within the clamping channel, the pulling rail being at least partially disposed between and, in contact with, the clamping rails and supporting an edge of the panel to be secured;
- actuation hardware configured to move the two clamping rails relative to the core rail in a driven direction;
- and
- further including a shear pin joint between each clamping rail and the core rail wherein the shear pin joint comprises a shear pin disposed in each clamping rail which interfaces with a slot in the core rail, wherein each clamping rail is prevented from sliding out of the core rail.
A rail system for securing a panel, comprising:
- a core rail having a clamping channel, wherein the clamping channel is defined by mutually opposed inclined surfaces;
- two clamping rails disposed mutually opposed within the clamping channel, each clamping rail having an inclined surface which bears upon one of the mutually opposed inclined surfaces of the clamping channel, and, each clamping rail being configured to bear upon a face of a panel to be secured;
- a pulling rail disposed within the clamping channel, the pulling rail being at least partially disposed between and, in contact with, the clamping rails and supporting an edge of the panel to be secured;
- actuation hardware configured to move the two clamping rails relative to the core rail in a driven direction;
- and
- further including an alignment device, the alignment device comprising:
- an interface member, an angular adjustment member, and, an axial adjustment member;
- the angular adjustment member being pivotally connected to the interface member and connectable to a door pivot;
- the axial adjustment member being connected to the interface member such that the interface member is axially moveable inwardly and outwardly with respect to the axial adjustment member;
- means for attaching interface member to the core rail;
- wherein, when the alignment device is installed in the core rail, the interface member is slidable within the core rail and the axial adjustment member is fixed to the core rail;
- wherein, when the alignment device is installed in the core rail and the angular adjustment member is connected to a door pivot, the core rail can be moved axially inward and outward with respect to the door pivot by causing the interface member to move relative to the axial adjustment member;
- and
- wherein, set screws installed in the core rail are configured to bear against an edge of the angular adjustment member and to be equidistantly spaced about the door pivot, such that adjustment of the set screws angularly moves the core rail with respect to the door pivot.
