Finally, the sealing and cushioning strip 34 is forced into place s0 that the portions 35 and 33 are firmly engaged in the groove 21. It should be noted that the normal section of the sealing strip is such that the portions 35 and 36 must be compressed toward each other while the strip is being inserted in the grooves 2l, whereupon the forked portions 35 and 36 then expand to press againstthe sides of the gIOOVe.
The inner ilat surface 38 of the sealing strip 34 engages the rear sides and the ange 33 of the window pane binding 3| so that the window pane 30 is held in suspension between the sealing strip 34 and the arm 20 of the front frame strip I1.
A slightly modied construction is illustrated in Figure 4. This differs from the embodiment shown in Figure 3, principally in the sectional shape of the sealing strip. In this instance the sealing strip 4I is of arcuate section. One end is engaged in the groove 21 and bears against the rear wall thereof. The other end of the strip 4I bears against the window pane binding 3| with the flange 33 of the latter overlying the edge of the sealing strip 4 I.
In accordance with the invention the front and rear frame or sash strips I'I and I8 are preferably formed of aluminum which is extruded in sectional shapes as shown and described. The door or other structure having the window opening may be of any suitable material, but is preferably of metal. such as stainless steel, aluminum, or the like.
It will be noted that the invention provides a window assembly which is easy to manufacture and assemble and in which the Window pane is mounted so as to withstand any jars or jolts to which the door, or other structure, may be subjected. Moreover, the structure presents a neat appearance as there are no screw heads or the like visible after the frame has been assembled with the window pane in place.

1. A window frame structure for windowopenings in doors and the like comprising, a front frame strip, said front frame strip being substantially T-shaped in section, a rear frame strip, said rear frame strip in section having an arm strip portion and a lateral strip portion, said lateral portion having an undercut groove for receiving a rubber sealing ring, and means for securing said frame strips to the edge of a window opening with the central portion of the front ,y frame strip disposed on the edge of the window opening and the lateral portion of the rear frame strip overlying said central portion.
2. A window assembly for building structures and the like comprising, a window pane having an edge binding, a window frame, said window frame being comprised of a front frame strip and a rear frame strip of extruded aluminum or the like, said front frame strip being substantially T-shaped in section and having a central strip portion disposed for engagement with the edge of the window opening and arm strip portions, one of which engages one side of the building structure adjacent the opening and the other of which engages one side of the edge binding of the window pane, said rear frame strip having an arm strip portion for engaging the other side of the building structure adjacent the edge of the window opening and a lateral strip portion for overlying the central portion of said front frame strip, said lateral strip portion having an undercut groove, means for securing said front and rear frame strips in the positions defined, and a sealing strip of compressible material, said sealing strip having one edge disposed in said groove and another portion engaging the other side of the edge binding of said window pane.
