We S/G/p Pflesso/v United States Patent O WINDOW SASHIES WITH A SUPPORTING BED FOR AT LEAST THREE PANES The present invention refers to window sashes with a plurality of window panes, namely, an exterior pane, an
interior pane and at least one intermediate pane arranged between the exterior and interior panes and dividing the space between the same into an outer air space and an inner air space communicating with the outer air space.
The invention has for its object not only to facilitate the insertion of the window panes by the use of a supporting bed, wherein the Window panes may be inserted one at a time, but also to form said supporting bed so that the communication between the air spaces inthe window is mediated by the supporting bed.
In a window sash according to the invention the communication between the air spaces is mediated by a channel formed in the supporting bed and paralleling the plane of the window, said channel being ofv a width which is larger than the thickness of the intermediate pane, so that with the exception of edge supports, if any, for the intermediate pane the edge of the latter projecting into the channel, and the portions of the lateral surfaces of the intermediate pane adjacent to said edge, are free from the bottom and the lateral surfaces of the channel. This will provide for a free circulation of air between the air spaces, so that deposit of moisture on the window panes is prevented.
The facilities for avoiding formation of moisture are augmented considerably, if such measures be taken that the air spaces are entirely shut off from a communication with the surrounding atmosphere both interiorly of the window and exteriorly thereof. By reason of this supporting bed may be provided with channels for the exterior pane and the interior pane, with the panes retained in said channels with a tight fit.
In order that the intermediate pane shall be retained in its proper position in the channel of the supporting bed, there may be provided suitably spaced supports in the channel for the edges of the intermediate pane.
For the continued description the following definitions are introduced for various window parts. The interior side or pane of the window is understood to be the side or pane thereof facing the room, in the wall of which the window is inserted, and the exterior side or pane is understood to be the side remote from said room. The inner edge of a window sash or a frame constituting a portion of a window sash is understood to be an edge facing inwardly onto the middle of the window sash opening, and the outer edge is understood to be the peripheral edge remote from said middle.
A few examples of applying the invention are illustrated in the drawing, wherein Fig. 1 shows a cross section through the lower portion of a window sash according to a first form of embodiment, and wherein Fig. la is a similar representation of a second, Fig. 2 of a third and Fig. 3 of a fourth embodiment of the invention. Fig. 4 is a diagrammatic representation of a window sash with a supporting bed according to the invention as viewed toward the inner edge of the sash.
2,883,7 18 Ptented Apr. 2s, 1959 rice The sections shown in Figs. yl and 2 may be taken on line I-I in Fig. 4, and the section according to Figs. la and 3 may be conceived of as taken on line Ia-Ia in Fig. 4.
In the construction according to Fig. 1, the supporting bed consists of a moulding or bar 1 of sheet-metal, for example, said moulding or bar extending along and round the whole circumference of the window sash ,2, which latter is herein taken to consist of wood. The moulding 1 forms, at each one of its longitudinally extending edges, L-shaped anges, 3, 4 for an exterior pane 5 and an interior pane 6, respectively, said panes being retained with a tight tit by means of holding llets 7, 8 and a suitable intervening packing material 9.
An intermediate pane 10 divides the space between the exterior pane 5 and the interior pane 6 into an outer air space 11 and an inner air space 12. These air spaces communicate with one another through a channel 13 receiving the edge portion of the intermediate pane. The intermediate pane, which like the panes 5 and 6 may consist of ordinary window glass, is of a thickness which is smaller than the width of the channel, so that the lateral surfaces thereof are free from the opposed sides 14, 15 of the channel. The intermediate pane is kept in position in the middle of the channel by means of suitable block supports 16 fitting the edge of the intermediate pane (Fig. 4), so that spaces 17 are also provided between the actual edge surface of the intermediate pane 10 and the bottom of the channel. lAix.' may thus ow from one air space into the other trans versely through the channel past the edge of theintermediate pane.
The construction shown in Fig. la differs from that described only in that the supporting bed consists of a solid moulding 1 of plastic or the like bearing with the whole of its outer edge on the inner edge 18 of the sash 2. The distance or supporting material 16 is shown in Fig. 1a, but this material obviously extends only for short distances of the length of the channel 13, so that free passages for circulating air are left between them, as shown in Fig. 4.
Fig. 2 shows an application to a wooden sash 2, which is covered exteriorly by sheet-metal 19. This covering is provided with a flange 20 projecting inwardly in front of the exterior pane 5 and with a ange 21 projecting inwardly along the inner edge of the wooden sash, said anges forming, together with the supporting moulding 1, a channel for the edge of the exterior pane 5 and for the packing material at said edge. The supporting bed is constructed in the same manner as in Fig. 1, but the sash 2 is shown with an abutting fillet 22 on the outer edge thereof. With this abutting fillet 22 the sash bears on a flange 23 of a metal covering on a Window frame 25.
The construction according to Fig. 3 differs from that shown in Fig. 2 substantially only with respect to the formation of the wooden sash 2, which is devoid of a .special wooden labutting fillet. Here, abutting takes place Iagainst the covering flange 23 of the frame directly through the metal covering 19 of the sash 2,
The channel 13 extends round the circumference of the intermediate pane 10, and in :all embodiments the upper .and lower edges of `at least the intermediate pane are supported by suitably spaced distance members 16. These distance members may be replaced at the lateral edges by holding fillets extending along the whole or major portion of the lateral edges. In such windows, the air in the intermediate space between the panes 5 and 6 will iiow down into the air space having the lowest temperature, transversely through the channel 13, and up :into the .air .space having the higher temperature. In
assente cold weather, air will thus flow down along the `cold exterior pane 5 into the air space 11 through the channel 13 at the lower edge of the intermediate pane, `as shown by the arrows, and up along the warmer interior pane 6 into the airspace 12 and transversely through the channel ,at the upper edge of the intermediate pane back to the `outer air space 11.
The supporting bed also facilitates the mounting of the window panes, inasmuch as they may be arranged in the supporting bed one at a time prior to or after the insertion of the latter in the sash, ordinary window glass then permitting of being made use of.
What I claim is:
1. ,A window sash comprising a peripheral sash frame, an exterior pane, an interior pane, and an intermediate pane mounted between said exterior and interior panes and dividing the space between the exterior and interior panes into an outer air space and an inner air space, a removable supporting bed extending along the inner `peripheral edge of the sash frame to keep said panes in proper position, said bed dening a central longitudinal U-shaped channel along the entire length of said inner edge and adapted to receive the edge of the intermediate pane, means in the channel for spacedly supporting said intermediate pane Vfrom the bottom and from the s-ides of the U-shaped channel, the width of said channel being greater than the thickness of the intermediate pane forming passages for circulating air between the lateral surfaces and the bottom edge of the intermediate pane and the lateral surfaces and the bottom of the channel; said bed also including L-shaped anges forming seats for the exterior pane .and the interior pane respectively, and said sash frame comprising retaining means cooperating with the L-shaped anges to retain the exterior ,and interior panes with a tight t to seal the air spaces between thepanes against the surrounding atmosphere; `at least one of said retaining means being removable whereby the panes can be inserted :and removed one at a time.
