This invention relates to windows and in more particular to the closure assemblies for the ventilating areas in windows.
This is a continuation-in-part of my copending application Serial No. 129,669 flledMarch 8, 1937,
4 An object of this invention is to provide a closure provided with a flexible Contact engaging the frame surrounding the closure.
Another object of this invention is to provide a closure for Ventilating areas of windows that is cheap, eicient, durable and dependable, that makesy good contact so as to protect the interior of the building from the elements.
unitary structure( for the closure and its screen that may be inserted as a unit into the Ventilating area.
Another object of this invention is to provide a composite frame for a Window wherein parts are molded from plastic molding material.
Other objects and advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.
In the drawing,
Fig. 1 shows a vertical sectional View of the preferred embodiment.
` Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. 1. y
Fig. 3 is a vertical sectional View of a modification.
Referring to the drawing, a plurality of transversely disposed T-shaped duo-functional muntin and detention bars divide the window into a plurality of spaces, some of which are provided Awith window panes 22, leaving a group of spaces 24'Vacant as a Ventilating area. In order to protect occupants of the building during inclement Weather it is desirable to provide a suitable closure for the Ventilating area 24. The closure includes a sheet metal member 26 pivotally attached by hinges 28 to the muntin bar extending across the top of the Ventilating area. The top and bottom portions of the sheet metal member 26 are provided with 'channels 30 preferably integral with the body portion 26. The channels 30 house sealing material 32, such as felt or the like. The felt is adapted to abut the inwardly projecting flanges of the muntin bars bounding the top and the bottom of the Ventilating area.
'I'he sides of the closure 26 are preferably provided with reentrant iianges 34 adapted to grip a metallic weather stripping member 36 substantially U-shaped in cross sectional area. One leg of each of the weather stripping members 36 is mounted in the bight formed between the main body portion 26 and the reentrant flange 34, and clamped therein. The other leg oi each of` the weather stripping members forms a flexible contact intermediate the closure and the inwardly projecting flanges of the vertically disposed muntin bars bounding the Ventilating area. From the foregoing description it can be readily seen that the closure is mounted Within the confines of the muntin bars, the main body portion 26 being in substantial alignment with the glazing 22.
Although the main body portion 26 has been described as consisting of sheet metal, it may consist of 'a sheet of translucent or transparent material molded from a suitable plastic molding material, such as nitrocellulose or phenolic condensation products.
The closure is adjusted and held in closed-posi- `tion by a chain 3B, which may be locked onheld taut in any suitable manner. As it is not feasible to have the muntin bars 20 extend continuously across the Ventilating area, suitable detention bars 40 are utilized to prevent escape oli bodies through the closure. In order to prevent the passing of small bodies and in order to provide protection against insects, a screen 42 iixedly attached to a metallic frame 44 is mounted over the Ventilating area in contact with the flanges of the muntin bars 2li bounding the Ventilating area. Y For some installations the screen frame 44 and the detention bars 40 mayy be xedly attached to each other.
Referring to the modication disclosed in Fig. 3, the closure and screen assembly have been mounted so as Ato be partially enclosed by the stems of the muntin bars 20. In this modification the movable closure 'lll includes a frame made either from metal or from suitable molding material. Said frame includes members 12 substantially L-shaped in cross sectional area. The closure 'l0 is pivotally attached by hinges 14, only one of Which is shown, to the web of the muntin bar 20 extending across the bottom of the ventilating area. The closureis held in closed posi-v tion `by a suitablev latch 16. v
The closure assembly 80, which has been shown as a screen, projects through the Ventilating area. The screen frame 90 is formed from anglebars made either from metal or from a plastic molding material. These angle bars have the flanges 90a, projecting through the Ventilating area and supporting the screen 84 suitably attached thereto. An abutment or snubber 96 attached to the lower flange 90a holds the screen frame at a proper height. A stop 91 is arranged in hooked relation lill Cil
with the flange of the detention bar 20 to prevent the screen frame from bodily removal inwardly. 'Ihe upper flange 90a is held in position by a diagonally arranged screw 38.
Flexible metallic members 99 are arranged in.
hooked relatio-n over they outwardly projecting flanges 93h of y the angle bars 90 forming the frame for the screen. The ilexible members 99 are clamped between the inwardly projecting iianges of the muntin bars 20 bounding the ventilating area and the movable frame of the closure, so as to provide a double contact between the exterior of the window and the closure, that is, one contact between the inwardly projecting flanges of the detention bars and the other contact with the frame of the movable closure.
A spring 29, which may be a coil spring, tends to bias the closure 26 into open position,- so that when the chain 3B is released from the inside of thebuilding the closure 26 automatically moves into open position.
vAlthough the preferred modification of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, which generally stated consist in a device capable of carrying out the objects set forth, in the novel parts, combination of parts and mode of operation, as disclosed and defined in the appended claims.
