Gottesleben, Detroit, Mich., assigner to Twin Pane Corporation, Detreit, Mich., a corporation of Michigan Filed Feb. 2S, 1962, Ser. No. 176,228 3 Claims. (Cl. 2li-56.5)

This invention relates to a window construction and more particularly to that type of window construction which requires no manual application of putty to the window after the glass has been installed.

It is a further object to provide a window construction which is particularly adapted to the use of a double pane combination which provides a thermal insulation.

There are a number of Window installations today which still utilize the wood frame which is adapted for standard glazing wherein a recess receives a pane of glass which is puttied in place.

It is an object Of the present invention to provide a double pane glass assembly which can be moved in to a wood frame and which will automatically lock and seal in said frame.

It is a further object to provide a thermal pane construction in which the entire unit can be handled as a single member.

It is a further object to provide as a part of a combination an extruded frame section for the window unit which is designed for use with a double pane unit.

Other objects and features of the invention relating to details of construction and operation will be apparent in the following description and claims.

Drawings accompany the disclosure and the various views thereof will be briey described as follows:

FIGURE l, a sectional view of a window assembly constructed according to the present invention.

FIGURE 2, an exploded view showing the double pane frame unit and the receiving frame.

FIGURE 3, an enlarged view showing the manner in which the window unit is locked into the frame.

FIGURE 4, a perspective view of a corner of the window unit assembly.

Having reference to the drawings, in FIGURE l a primary or outer wood frame lt) has a top run l2 and a bottom run 14 with side runs 16. The bottom and the side runs are each provided with a recess 2? which consists of an open-sided groove extending around the outside of the frame. As shown in FIGURE l, about 1A inside the edge of the Wood frame is a small groove 22 which extends the entire length of the bottom and side runs in the groove 20. This is primarily simply a marking groove for the use of glazing materials but it can be used to cooperate with a locking member of the assembly to be described, The devices shown in FIGURES 2 and 3 eliminate this groove since it is not essential to the operation of the device. The wood from which the window frames are made is usually a relatively soft wood; and as will be described later, the locking element for the assembly can gouge into this wood and become firmly locked.

The upper run does not have the groove 2@ but is provided With a narrow surface slot 241 which has its inner surface spaced inwardly from the outside of the window frame the same distance as the inner wall of the groove 2t). The window assembly unit comprises a secondary frame, three sides of which are formed of a channel section shown best in FIGURE 3.

This channel section, preferably of extruded plastic, has a base 30 with two

side walls

32 and 34. The side wall 34 continues below the base section in a short wall 36. On the bottom of the base 3@ on the same side as Wall 32 is a small channel section which has re-entrant grooves provided by flanged portions 3S and lili.

The channel described can be used for the lower run and the two side runs of the glass assembly insert. The upper plastic channel is preferably formed (FIGURE l) with a base section 42 having

side walls

44 and 46 with the small double channel section 48 adapted to project upwardly into the groove 24 of the upper run 12 of a window frame.

Small closed channels Si) of a light material, such as aluminum, are formed into a frame member which creates a spacer between two

glass panes

52 and 54 lying inside the

walls

32 and 34 of the bottom and side sections of a frame arid the walls 44 and d6 of the upper section. The section of the spacer is narrower at the outside edge 55 so that contact with the glass is spaced inwardly from the edges. Thus, with proper dimensioning, as shown in FIG- URE l, the glass panes are snugly inserted between the walls of the secondary frame members, which are preferably formed of a resilient plastic material, and the outer walls of the spacer elements Sli.

The corners of the plastic secondary frame members can be readily secured together and sealed by a plastic solvent or a heat seal, creating an insulating air pocket between the two

panes

52 and 54. Inserted in the channel formed between members 38 and d@ is a locking strip which is composed of a base titl and a resilient locking ange or blade 62.

This material can be formed of a light metal material which is pushed into the channel formed by the members 33 and 4G. When the two sides and the bottom of the assembled window unit are fitted with these elements, the window unit within the secondary frame can be installed into the frame by tipping the upper double ange 4S into the groove 24 of the top run 12 of the frame and pushing the remainder of the window unit into place in the groove 2li. This motion causes an inward flexing of the anges 62 and when the edges reach the groove 22, these anges snap into place in these grooves as shown in FIGURE l.

In the embodiment shown in FIGURES 2 and 3, it will be noted that the locking blade 62 has a squared oft edge which creates a sharp corner 64. This sharp edge 64 readily moves into the frame 14 in the direction of the arrow shown in FIGURE 2 because of the angle of the blade 62 but again, due to this angle, the edge digs into the wood so that it will not move out of the frame but rather will simply gouge into the wood and lock itself securely in place.

In the installation of the assembled frame into the sash, it is preferable that a suitable sealing material be extruded around the frame, for example, in the area A in the corner of the recess Ztl of FIGURE 2 and in the area B in the corner between the wall 36 and the base 30. Thus, as the frame is moved into the place, it seals both on the inner surface and the outer surface.

The window assembly is, therefore, securely held in place; and it will be noted that the slightly resilient plastic flanges 36 lie over the outside of the window frames beyond the grooves 20 so that the entire unit is weather sealed in the frame. Thus no additional caulking or putty need be applied after the setting of the glass to provide a tight window assembly which, in addition to being weatherproof, is also a thermal insulation protection for the area in which the window is finally mounted.

The assembly of the glass into the frame is thus accomplished very rapidly and the assembly is locked into place until such time as the panes might be broken and it is necessary to replace them. The assembly units are such that the installation of the glass can be accomplished either in the shop or at the place in which the Window is being installed. The glass assembly is a complete Y 3 unit in itself which can be readily transported independently of the frame.
