Description

SEALING AND DRAFT EXCLUDING DEVICE Filed Au 25, 1956 Patented Feb. 7, 1939 UNITED STATES PATENT OFFICE Application August 25 1936, Serial No. 97,855
In Switzerland August 31, 1935 2 Claims.
My present invention relates to sealing or draft excluding devices for windows and doors.
The primary object of my invention is the provision of a flexible sealing band which lies in the closed position of the window or door, in a hollow space formed between the casement and window or door frame.
Another object of my invention is the provision of a fillet supporting said flexible sealing band, adapted to be secured on one of the rabbet parts.
A further object of my invention is the provision of a gas tight counter-support on which bears the free longitudinal edge of the sealing band in the closed position of the window or door.
Other and further objects of the invention will be apparent to those skilled in the art, from a reading of the complete specification and the appended claims.
In the accompanying drawing,
Fig. 1 is a plan view of a window in its closed position, the upper part being broken away, provided with the sealing device.
Fig. 2 is a section taken on the line A--A of Fig. 1,
Fig. 3 is a detail view on enlarged scale, of parts of the section of Fig. 2,
Figs. 4 and 5 show a detail in sectional end elevation and front elevation respectively and Figs. 6 and '7 show a modification of the detail views similar to the views of Figs. 4 and 5.
In Figures 1 to 3 is shown a single swing casement window constructed in metal. The casement frame '2 carrying the glass panel I is hinged to the window frame by means of hinges 3 one of which being shown in the drawing. The two frames engagein the closed position into each other in rabbets which together form a hollow space 5 surrounding the sash frame 2. The sealing device itself is mounted in this hollow space 5, spring sealing bands 6 being pressed with one longitudinal edge against rubber or the like on the easement frame 2 and secured by the other longitudinal edge to the frame 4 by fillets 1, provided with substantially V-shaped grooves to receive the longitudinal edges of the sealing band which are suitably bent back to fit into the grooves as shown. The V-shaped grooves could also be arranged on the frame 4 itself instead of being formed in fillets 1. The edge could also be secured by nails or screws on the frame 4. It will be noted that one end of the wall forming the V-shaped groove is formed to provide an abrupt shoulder l to be engaged by the free edge of the bent end of the sealing band to prevent movement of the band outwardly with respect to the groove and thus hold the band to assist in the resilient bearing of the opposite end of the band for sealing purposes.
There are provided on the rabbet parts of the window frame opposite the rabbet parts carrying the sealing bands, counter-supports 8 projecting into the hollow spaces 5 and on which flexibly bear the free longitudinal edges of the sealing bands 6 in the closed position of the window. These counter-supports consist of a strip of resilient material e. g. rubber preferably inserted in a metallic frame S. They have for their object to attain a tight joint between the free sealing band edge and its point of support to prevent the penetration of gases. In a groove 9 of the fillets i can be inserted a sealing agent such as plastic material or a plastic material such as cement hardening subsequently, whereby a penetration of air or gases due to passages or grooves formed in consequence of age of the support, is prevented and a window or door provided with such a sealing device is perfectly tight both as regards draft and gases. A similar groove may be on the counter-support 8.
The rear part of the metal frame 8' may be made with solid walls or consist only of individual crossbars. In some cases the counter-support may be omitted in which cases the free edge of the band 6 bears on the rabbet 2.
While I have shown and described an embodiment of my invention, I desire to have it understood that the showing and. description are merely illustrative and that modifications and changes as to form, shape and material may be made without departing from the spirit of the invention and within the scope of the appended claims.
Having described my invention in detail, what I claim and desire to be secured by Letters Patent is:-
1. The combination of a window frame and a sash, one fitting within the other and spaced apart, a strip secured tothe inner surface of the window frame and formed with a substantially V-shape groove, a flexible sealing element having its outer edge bent to engage the V-shape groove in the strip, the opposite edge of the sealing element bearing against the outer surface of the sash and free thereof.
2. The combination of a window frame and a sash, one fitting within the other and spaced apart, a strip secured to the inner surface of the window frame and formed with a substantially V-shaped groove, a flexible sealing element having its outer edge bent to engage the V-shape groove in the strip, a resilient sealing strip on the outer surface of the window sash and within the space, the opposite edge of the sealing element bearing against the resilient strip and free thereof.
