Abstract: There is described a profiled sash section for a window sash holding a window pane and intended for being installed in an outer frame of a blast resistant window. The sash section includes a main member enabling inter-engagement between the profiled sash member and the outer frame a window pane holding member for accommodating and securing an end portion of said window pane in the profiled sash member, and a reinforcing member designed to support the end portion of the window pane and to transmit blast pressure, if incidentally applied to the window pane, to the main member. For at least partially absorbing blast pressure energy applied to the window pane, the sash section is provided with damping means for deforming up to predetermined limit. Also described is a blast-resistant framework for a casement window, including the window sash assembled from the mentioned profiled sash sections and adapted for rigidly and air-tightly securing the window pane in the holders of the profiled sash members.

Abstract: A lightweight bus window construction has a window frame with a generally U-shaped channel around its lateral edges. A step is provided adjacent the opening of the U-shaped channel along the lower edge with a lip extending above the step along the edge. A thin sheet of plastic glazing material in the frame has its upper and side edges within the U-shaped channel along the upper and side edges, and the lower edge of the sheet rests on the step. The sheet is sufficiently thin that it will flex for fitting the upper and side edges into the channel without disassembling the frame. An elastomeric gasket fills the space between the sheet of glazing material and the face of the U-shaped channel on the opposite of the channel from the lip. The gasket includes a portion along the lower edge extending upwardly above the opening of the U-shaped channel and engaging the face of the sheet of glazing material opposite to the lip. The elastomeric gasket secures the glazing material within the frame.

Abstract: A storm-resistant window includes a mechanism for preventing the blowout of a movable sash when wind pressure pulls the sash outwardly. In a single hung window having a slidable lower sash, the mechanism consists of a first rib projecting downwardly from the bottom rail of the lower sash and a second rib projecting upwardly from the top of the sill member of the window frame. In a closed position of the window, the first rib lies inwardly adjacent the second rib such that, if wind pressure pulls the movable sash outwardly, the first rib will contact the second rib, preventing the bottom rail of the movable sash from moving outwardly. In an alternate embodiment, one of the ribs may be replaced with a channel, so that the remaining rib is received in the channel in the closed position of the window.

Abstract: An overhead guard for a vehicle, in the form of a cab for a lift truck, that affords both protection and a high degree of overhead visibility with a relatively open grille work of steel bar and an impact-resistant glazing sheet. The glazing sheet is sandwiched between a rigid framework and a sheet metal panel having a large cutout for the overhead view. Gusset plates reinforce the corners of the framework and provide convenient mounting locations for an air circulating fan. Threshold adaptor brackets are mounted in step pockets of the vehicle chassis to simplify the door structure while permitting the cab to be effectively sealed from the environment when the doors are closed.

Abstract: There is described a profiled sash section for a window sash holding a window pane and intended for being installed in an outer frame of a blast resistant window. The sash section includes a main member enabling inter-engagement between the profiled sash member and the outer frame; a window pane holding member for accommodating and securing an end portion of said window pane in the profiled sash member, and a reinforcing member designed to support the end portion of the window pane and to transmit blast pressure, if incidentally applied to the window pane, to the main member. For at least partially absorbing blast pressure energy applied to the window pane, the sash section is provided with damping means for deforming up to a predetermined limit. Also described is a blast-resistant framework for a casement window, including the window sash assembled from the mentioned profiled sash sections and adapted for rigidly and air-tightly securing the window pane in the holders of the profiled sash members.

Abstract: The present invention provides a locater pin (1) for locating a first article such as a glass window panel (104) with respect to a second article such as a window frame (101) in a vehicle chassis (100). The pin (1) includes a head portion (2) for attachment to the glass panel (104) and an elongate stem portion (3) which extends from the head portion for receipt in an aperture (102,103) of the frame (101). In this way the pin is able properly locate the glass panel relative to the frame. The locater pin (1) further includes stress dissipation means (8) which is adapted to yield in the event that a stress load greater than a predetermined limit is transmitted through the pin between the glass panel (104) and the frame (101) to thereby prevent damage to the glass panel and/or the frame. The present invention also provides a window assembly incorporating such a locater pin (1), and a vehicle incorporating such a window assembly.

Abstract: A guard assembly for a framed opening in a structure includes mounting brackets attached to the framed opening. Each bracket has three angled flanges forming an intersection channel for retaining a grid work member extending between the mounting brackets. The grid work member is compressively urged into the intersection channels and further secured by locking screws extending through one of the angled flanges.

Abstract: A method of making a seal on a panel for a door or window by applying and curing a sealant on the surface of the panel is provided, preferably by screening the sealant onto the surface of the panel. The panel with the seal is mounted in a window or door frame such that the seal is disposed between the panel and the frame itself. To assemble the door or window, the panel may be inserted into “U” shaped grooves in the structural members comprising the door and the frame members assembled about the panel. The panel may have multiple layers with such seals interposed between the layers.

Abstract: A window retention system includes a door frame having an exterior panel, an interior panel, an opening therethrough defining an inner peripheral channel, the exterior panel includes an upright portion extending along the channel so as to be directed toward the interior panel; and a resiliently flexible window retainer strip yieldably interlocked with and thereby detachably mounted on the door frame. The retainer strip has a longitudinal axis and a first upright portion spaced from and in opposing relation with the upright portion of the exterior panel so as to delimit a first track in the channel and retain the window element therein. The strip includes a second upright portion laterally spaced from the first upright portion. The second upright portion is biased towards and yieldingly interlocks with the channel. A flange extends from the first upright portion of the strip to engage one of the door frame panels and thereby secure the first upright portion of the strip against rotation in a vertical plane.
