A window frame and a glazing strip or rim for a window panel in which the frame defining a window has a J-shaped channel with its open side facing toward the opening in the frame. The panel is surrounded on at least three sides of a rectangular panel by the glazing strip or rim which has a leg integral therewith and which is received in the frame channel. Such leg is flexible and resilient and can be bent to permit the free end thereof to ride over the shorter wall of the channel and snap into the channel. Preferably, the portion of the rim from which the leg extends is U-shaped in cross-section and embraces the outer edge portions of the panel. A resilient gasket is between the rim and the frame. If the rim is of metal, the wall of the rim remote from the frame has a line of weakening for tearing purposes. A resilient strip may be inserted between the leg and a portion of the rim. Also, a tool for inserting the panel in the frame and a double-glazed window.

An impact resistant window structure or the like, having a quick replaceable glazing assembly which comprises (a) a structural frame forming a primary opening, (b) said structural frame comprising a channel-forming member having a base portion, a front flange extending inward of said opening from said base portion, and a lip-forming flange spaced from said front flange, (c) said lip-forming flanges, in the structural frame forming an access opening larger than said primary opening, (d) said glazing assembly including a glazing panel of a size an shape corresponding generally to said openings, (e) said glazing assembly further including a glazing frame engaging and extending about the periphery of said glazing panel, (f) said glazing frame being formed of glazing strips of unitary, monolithic, extruded construction and including at least a base portion, a back flange extending from said base portion and overlying the back peripheral surface areas of said panel, and integral snap-in locking strips, (g) the base portions of certain of said glazing strips having front portions and said locking strips being integrally joined with said front portions and running lengthwise of said strips, (h) said locking strips extending at an angle rearward and outward with respect to said opening, (i) the glazing assembly of said glazing panel and glazing strips being of larger dimensions than said primary opening and, exclusive of said locking strips, smaller than said access opening, (j) the peripheral dimensions of said glazing assembly, including said locking strips, being larger than said access opening, and also larger than the opening defined by the base portions of said structural frame, (k) said locking strips being flexibly and resiliently related to the base portions of said glazing strips by reason of a reduced thickness, hinge-like connection thereto, whereby said locking strips are resiliently displaceable toward said base portions, (l) said lip-forming flanges being recessed for locking engagement with the backwardly extending free end of said locking strips upon insertion of said glazing assembly into said structural frame, (m) resilient sealing means interposed between the front flanges of said structural frame and the front peripheral surface portions of said glazing assembly to form a seal, (n) said sealing means being disposed about substantially the entire periphery of said structure and being sufficiently compressible to accommodate forward movement of the displaced locking strips past said lip-forming flanges, (o) said sealing strips being retained under substantial compression by said glazing assembly when said locking strips are engaged in said recesses.
