This invention relates to a novel and useful magnetically operated shutter and storm window assembly.

The provision of two laterally spaced panes of glass in a window construction have for quite some time been recognized as a means for providing an insulation barrier between the inside of the window and the outside thereof. Accordingly, there have been constructed many ditferent types of storm window constructions utilizing a pair of laterally spaced panes of glass which are secured to the frame of the window construction in fluid tight sealing engagement therewith about the peripheral edges of the two panes of glass. In this manner, a sealed dead air space between the two panes of glass is provided and acts as quite effective insulation against the transfer of heat from lone side of the window construction to the other.

Since the advent of shutters having tiltable slats there has also been an attempt to combine a double pane storm window construction with a shutter assembly by mounting the shutter slats between the two panes of glass of a storm window construction. In this manner, not only is a storm window construction provided but also a window construction whose shutter assembly may be actuated to adjust the amount of light passing through the window. However, all previously known attempts at providing cornbined storm window and shutter assemblies have necessitated an actuator for actuating the shutter assembly disposed between the two laterally spaced panes in the storm window construction and the actuator must necessarily be operable from the exterior of one side or the other of the storm window construction. Consequently, various types of gear mechanisms with operating shafts projecting from one side of the windows have been provided but these types of constructions have had one serious drawback in that is is substantially impossible to positively seal the area between the laterally spaced panes of the window construction from the exterior of the window. Of course, if the shutter structure were provided with electric motor means disposed between the double panes of the window construction suitable electrical conductor means could be passed through the window frame in fluid tight sealing engagement therewith, but the provision of reversible electric motor means for operating a shutter assembly and storm window construction of this type would greatly increase the cost of production. Accordingly, it is the main object of this invention to provide a double pane storm window construction and shutter assembly whose shutter assembly may be readily operated from a position exteriorly of the area between the double panes of glass of the storm window construction and in a manner not necessitating communication with the area disposed between the spaced panes of the storm window construction.

A further object of this invention, in accordance with the immediately preceding object, is to provide a combined window and shutter assembly whose shutter assembly is disposed exteriorly of the window pane of the window assembly and which may be actuated from inwardly of the window construction without the provision of actuating means extending through any portion of the window construction.

A still further object of this invention, in accordance with the preceding objects, is to provide a combined storm window an dshutter assembly whose shutter assembly includes a rst magnetic actuator mounted for movement ICC in a plane generally paralleling and immediately adjacent one pane of the storm Window construction and constructed of ferrous material whereby a second and magnetic actuator may be disposed on a remote side of that window pane and moved in sliding contacting relation with the window pane in order to effect similar movement of the first actuator secured to the shutter assembly.

A final object tobe specifically enumerated herein is to provide a combined storm window and shutter assembly which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE l is a Vertical sectional view taken through the shutter and storm window construction of the instant invention;

FIGURE 2 is a vertical sectional View similar to that of FIGURE l but showing the shutter assembly in an alternate position;

FIGURE 3 is a fragmentary side elevational View of the storm window and shutter assembly;

FIGURE 4 is a fragmentary horizontal sectional View of the assembly illustrated in FIGURES 1 3; and

FIGURE 5 is a view in perspective showing the rst and second magnetic actuators of the shutter assembly.

Referring now more speciiically to FIGURES l and 2 of the drawings it will be seen that the storm window and shutter assembly of the instant invention is generally referred to by the reference numeral 10. The storm window portion of the assembly 11i is generally referred to by the reference numeral 12 and includes an open framework generally referred to by the reference numeral 14. The framework or window frame 14 includes upper and

lower members

16 and 18 and opposite side members 2t?. Each of the

members

16, 18 and 211 is similarly formed and may be formed in a manner rendering the frame 14 of one-piece construction. Each side of the frame 14 includes a recess 22 and a pair of

window panes

24 and 26 are secured in the recesses 22 in any convenient manner such as by air-tight caulking 28 or the like. In this manner, the peripheral edge portions of each of the

panes

24 and 26 are secured to the frame 14 in uid tight sealing engagement therewith and inasmuch as the frame 14 is itself constructed of fluid impervious material as are the

panes

24 and 26, the area 30 defined between the

panes

24 and 26 is sealed from ambient atmosphere.

A pair 0f mounting plates 32, see FIGURES 3 and 4, may be secured tothe inner surface of the opposite side members 20 of the frame 14 in any convenient manner. A plurality of shutter slats 34 are each provided with opposite end stub axle portions 36 which are rotatably journalled in the inwardly oifset mid-portion 38 of the mounting plates 32. In this manner, each of the shutter slats 34 is pivotally mounted for oscillatory movement about its longitudinal center line.

Each of the slats 34 includes a crank arm 40 which is apertured as at 42 on its free end and an elongated connecting member 44 is secured between the free ends of the lever arms 4l) for connecting the shutter slats 34 together for simultaneous and equal oscillatory movement.

First and second slide guide members generally referred to by the

reference numerals

46 and 48 are bonded to opposite surfaces of the pane 24 in any convenient manner and are generally U shaped in longitudinal cross section.

A first actuator generally referred to by the reference numeral 50 and comprising a magnet is guided for movement along the inner surface of the pane 24 by means of the rst slide guide 46 and a second magnetic actuator generally referred to by the reference numeral 52 is guided for movement by means of the second slide guide 48 for sliding contacting engagement with the outer surface of the pane 24. It will be noted from FIGURES 1 and 2 of the drawings that the slide guides 46 and 43 are disposed immediately opposite each other and accordingly that the

actuators

50 and 52 by means of their magnetic attraction for each other will each move in response to movement of the other.

A connector 54 is secured to an opening 55 formed in the first actuator 5G in any convenient manner and passes through an opening (not shown) formed in the slide guide 46. With one end of the connector 54 secured through the opening 55 and the other end ofthe connector 54 secured to the uppermost lever arm 49, upon vertical sliding movement of the actuator 50, the shutter slat 34 may be oscillated between the two positions illustrated in FIGURES 1 and 2.

It will be noted that an operating rod 56 is secured at its upper end to the lower end of an actuator 52, in any convenient manner and is slidably received through an opening S8 formed in the slide guide 48. The lower end of the rod S6 is provided with an operating knob e@ and upon vertical reciprocation of the knob 6d, the actuators 52 and 5t) will be similarly reciprocated thereby effecting oscillatory movement of the shutter slats 34.

By providing a shutter assembly which may be actuated from the exterior of a hermetically sealed chamber in which the shutter slats are disposed, the main objection to shutter slats will We eliminated. That is to say, there will be no opportunity for dust and other foreign material to collect on the shutter slats. Accordingly, only the outer surfaces of the

panes

24 and 26 must be cleaned.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:
