Abstract

A rail system for holding a panel, such as a plate glass pane, in a door and/or wall partition. The rail system includes a housing and a clamp member having a wedging geometry so that when the clamp member is actuated with respect to the housing in a first direction, at least a portion of the clamp member will move in a clamping direction, which is different than the first direction to clamp the panel.

  1. 1. A rail system for releasably securing a pane having at least one major surface defining a first plane, the rail system comprising: an elongated housing comprising: a first inclined surface oriented to be generally inclined with respect to the first plane; and a second inclined surface oriented to be generally inclined with respect to the first plane; a first clamp member comprising: an inclined surface located adjacent to the first inclined surface of the housing and oriented to be approximately parallel to the first inclined surface of the housing; and a pane clamping surface; a second clamp member comprising: an inclined surface located adjacent to the second inclined surface of the housing and oriented to be approximately parallel to the second inclined surface of the housing; and a pane clamping surface; a screw; and a nut threadably engaged with the screw and located to drive the first and second clamp members in a direction along the first plane in order to generate sufficient opposing clamping forces between the first clamp member and the second clamp member such that a pane can be secured between the pane clamping surface of the first clamp member and the pane clamping surface of the second clamping member; wherein the nut is an elongated strip having at least two threaded holes.
