Cl. 49-492 8 Claims ABSTRACT OF THE DISCLOSURE Window consisting of an outer frame and an inner frame both made up of hollow generally U-shaped sections opening toward the inside of the window with cover strips covering the open side of the frames. Interengageable elements are carried on the frames with some of those on the inner frame being moveable, and actuating means on the inner frame includes parts disposed inside the inner frame and connected to the moveable elements.

The present invention relates to a window frame having a profile of metal or synthetic material. With heretofore known window constructions of this type, the mounting of the actuating bars and the actuating elements pertaining thereto for the fittings cause considerable difficulties. While fittings are available the parts of 'which require little space when being assembled, there exists the drawback that with these fittings the fitting elements have to be arranged in the interlock, of the window. In view of the cutouts in the profile of the blind and wing frame, which cutouts become necessary, the manufacture of the Wll'ldOW frame is considerably increased in cost. Moreover, the actuating bars which are displaceable in the interlock have to be lubricated from time to time. In this connection, it is unavoidable that excessive lubricant deposits at the edge of the window wing. This edge is visible when the window is open and is not very appealing. Moreover, the curtains or drapes can easily be soiled thereby.

The present invention concerns a window arrangement swingable about one edge at the side or tiltable about the lower edge between closed and open positions. The window consists of an outer frame'for stationary mounting in a wall opening, and an inner frame which is moveable into and out of the outer frame.

The frames are in the form of hollow profile sections with each frame having the sections in abutting relation at the ends and interconnected by angular connectors. The profile sections have channels which open toward the inside of the window and are arranged with flanges on which cover or trim strips can be mounted.

The inner frame and outer frame have inner engageable elements for holding the window closed and open providing pivot axes on which the inner frame can tilt, and at least some of the elements on the inner frame are moveable while actuating means for the moveable elements are carried by the inner frame and include parts extending in the channel in the inner frame.

It is, therefore, an object of the present invention to provide a window frame which will overcome the above mentioned drawbacks.

It is another object of this invention to provide a window frame construction which will permit the installation of different types of fitting and ventilating systems.

It is still another object of this invention to provide a window frame which is simple in construction,

These and other objects and advantages of the present invention will appear more clearly from the following ice specification in connection with the accompanying drawings, in which:

FIG. 1 is an elevational view of the window according to the present invention looking at the window from the inside.

FIG. 2 is a cross section taken along the line II--II of FIG. 1.

FIG. 3 is a cross section along the line III--III of FIG. 1.

FIG. 4 is an isometric view of a window plug.

FIG. 5 is an isometric view of a follower for use in connection with the present invention.

FIG. 6 is an isometric view of a plug pin.

FIG. 7 is a fragmentary elevational view of the lower left-hand corner of the window looking at the window from the inside and with the cover strips removed.

FIG. 8 is a fragmentary elevational view of the lower left-hand corner of the outer frame of the window looking from the inside of the window and with the cover strip removed.

FIG. 9 shows the arrangement of the rotatable tiltable fitting on the wing frame.

FIG. 10 is a corner connection of the blind frame.

The objects outlined above have been realized by composing the blind and wing frame of a profile which is open at the inner side surface, while said open profile has formed abutment strips to its open side which abutment strips serve as cover interlock and as support for a cover strip closing the open side of the profile. In view of the design of the profile according to the present invention, the fitting elements can be arranged within the blind and wing frame. Inasmuch as they are located below the cover strips and thus are not visible from the outside, it is not necessary to machine their surfaces. The corner portions can be made strong and uncomplicated without weakening the corner connections of the blind and wing frame. As cover strips, preferably wooden strips are employed. Wooden strips are poor heat conductors: and thus prevent the formation of condensation on the inner window frame. In other words, the heat-cold bridge is interrupted. Moreover, such cover strips can be arranged on the window frame while any type of wood may be employed which matches the interior. Even when solid wood is employed, such pressure strip of wood remains in the lower price bracket because only strips are employed.

A further feature of the present invention consists in that the blind and wing frame which is composed of a profile open on the inner side surface is held together by corner connecting elements, which are inserted into the metal or synthetic profile and are connected thereto by an adhesive. Inasmuch as the profile is open on the inwardly located side surface, the areas to be provided with an adhesive can be covered by an adhesive from the inside. These areas are not visible from the outside so that a post-machining of the outer surface of the frame will not be necessary at the abutting areas.

Instead of an adhesive connection, it is also possible when making the frame of steel and synthetic material to employ a welding connection. The profiles of the blind or wing frame which are cut for mitering are welded together at the respective joints. Since the welding areas are not visible from the outside, also in this instance the otherwise necessary post-machining operations are not necessary. In order to prevent any interference of the corner connecting elements with the installation of the actuating members of the fitting, it is advisable so to design the window frame that the metallic or synthetic profile for the blind and wing frame will have two chambers accessible toward the inside, of which one chamber will permit the insertion of the corner connecting elements while the other chamber will permit the installation of the actu ating members for the fittings. The inner chamber of the blind and window frame which is not subjected to any load by the actuating members of the fittings, may be filled with a heat damming insulating material. This is not possible when a closed tubular profile is employed.

With a wing frame made according to the present invention, the window lugs are preferably with the lug ears connected to the abutment strips formed onto the frame profile. In view of this arrangement, the strength of the wing frame is considerably improved. In order to permit the employment of Wing frames for the left as well as for the right abutment, it is advantageous to arrange the window lugs at the corners of the frame profile.

The lug ears or extensions are designed for suspending and guiding actuating members of the fitting. In view of this design, the turning and tilting links and the actuating members do not require any additional connecting and guiding plates. In order to permit a power interlock between the actuating bars and the displaceable lug pins, the lug extensions are provided with a perforation in which there is arranged a follower which connects the actuating bar with the lug pin. The said follower is laterally guided between the abutment strip formed onto the frame profile and the sealing strip. It is advisable to detachably connect the follower to the actuating bar and to the lug pin. In view of this detachable connection, the actuating members can be installed with a considerably greater ease.

Referring now to the drawings in detail, the window frame shown in FIG. 1 is a one-Wing window. It is composed of metallic profiles, for instance aluminum profiles and forms a blind frame 1 and a wing frame 2. The wing frame 2 is by means of window lugs 14 rotatably and tiltably arranged in the

counter bearings

19, 20 and 23 arranged on the blind frame 1. The wing frame 2 is furthermore equipped with two fittings and 11 of which the fitting 10 serves for opening of the wing frame 2, whereas fitting 11 serves for tilting the wing frame 2.

At the left side of the window in FIGURE 1, three plungers 16 are received in the sockets or counter bearings 19 illustrated, and can be withdrawn therefrom so that the window frame will pivot about an axis defined by the three plungers 16 at the right side of the window. The plungers 16 at the right side of the window consist of two upper plungers that can be withdrawn from their sockets 19 and a lower plunger which permanently engages its socket 23 and which socket 23 is tiltable on a horizontal axis 24. Axis 24 is coaxial with a plunger 17 in about the middle of the bottom of the window frame that can be inserted in its pertaining socket 20. To tilt the window about axis 24, plungers at the left side of the window and the two uppermost plungers at the right side of the window are withdrawn from their sockets. Withdrawing of the last mentioned plungers from the sockets also inserts plunger 17 in its socket and the window can then be tilted outwardly at the top.

As will be evident from FIGS. 2 and 3, the blind frame 1 and the wing frame 2 are made of a profile which is open on the inner side surface. The open side of this profile is covered by

cover strips

5, 6 of wood which serves for stiffening or reinforcing the profile frame and for preventing the formation of water deposits. As supporting surfaces for the cover strips 5, 6, the open side of the profile has formed thereto two

abutment strips

3, 4. To the abutment strips 3, 4 are connected the extensions of the lugs 14, by means of screws or rivets 33. According to this embodiment, the inner chamber of the profile for the wing frame 2 is sub-divided into two

chambers

12 and 13. Chamber 12 serves for the insertion of the corner connecting elements 7, whereas chamber 13 serves for mounting the actuating bars 8, 9 and the transmission parts pertaining thereto for the

fittings

10 and 11. The extension 15 is furthermore arranged for mounting

fittings

10 and 11 and of the joint lever 34 as well as for guiding the actuating bars 8 and 9. With the embodiment according to FIG. 2, the extension 15 has rotatably journalled thereon a roller 22 by means of which the actuating bar 8 is laterally guided.

FIGS. 3, 4, 5 and 6 show a different embodiment of the present invention. According to FIGS. 3, 4, 5 and 6 the actuating bar 9 is guided by a guiding strip 25 formed from the extension 15. The extension 15 is furthermore provided with a perforation 26 in which there is mounted a follower 29, said follower establishing the power interlock connection between the actuating bar 9 and the lug pin 16. Follower 29 on one hand by means of pivot 10 engages corresponding bores of the actuating bar 9 and on the other hand by means of the angled-off end 31 engages a recess 32 of pin 16. Pin 16 is longitudinally displaceable in bore 28 of the window lug 14. The passages 27 provided in the extension 15 are intended for receiving the screws or rivets 33 intended for the connection. The inner chamber of the profile, which is not placed under load by the actuating bars 8, 9 and the actuating members pertaining thereto, is filled with a heat damming substance, for instance insulating foam rubber material.

As will be evident from FIGS. 7 and 9, identical window elements 14 are mounted on the band and the actuating side of the wing frame 2. The identical design of the members 14, in addition to simplifying the keeping of stock, has the further advantage that the window can be employed on the building lot for left as well as right abutments. The

pins

16, 17 are employed either as pivot or as closure mandrel. The window members arranged at the corners and in the center of the wing frame 2 are by means of the screws or rivets 33 connected to the abutment strips. The window elements also contribute to strengthening, i.e. reinforcing the pro file.

As will furthermore be evident from FIGS. 7, 8, 9 and 10, the individual legs of frame 1 and frame 2 are out at the corners for mitering and are held together by corner connecting elements 7. The corner connecting elements 7 are introduced into the interior of chamber 12 and are glued to the profile by means of a metal adhesive. When employing large windows, the corner connecting elements 7 may as shown in FIG. 10 also be aditionally screwed to the profile by means of screws 33. In this connection, it is advantageous to employ selfcutting thread screws. The bottoms of the screws 33 are arranged below the cover strips 5, 6 and therefore are not visible from the outside.

The operation of the window is the same as with heretofore conventional window constructions. For purposes of opening the window, the handle 18 arranged at the fitting 10 is turned into opening position. As a result thereof, the pins 16 on the transmission side of the window frame 2 are pulled out of the stationary socket-s 19 by the actuating bars 8. The wing frame 2 may now be opened by swinging it about the vertical pivot axis at the opposite side of the window. When the wing frame 2 is to be tilted outwardly from the top, prior to the opening of the wing frame 2, first lever 21 of the turning tilting fitting 11 is brought into FlG. 9 position. In this connection, the pin 17 serving as tilting axis is displaced into the counter bearing or 'socket 20, while simultaneously, the two upper pins 16 at the right side of the window are displaced by means of the actuating bars 9 and pulled out of their respective counter bearings or sockets 19. Handle 18 at the left side of the window is then actuated to withdraw the associated pins 16 from their sockets 19. At this time, plunger 16 at the lower right hand corner of the wing or inner frame is also tiltable with its support 23 about the pivot axis 24 and cooperates with pin 17 in establishing the pivot axis at the bottom of the window.

It is, of course, to be understood that the present invention is, by no means, limited to the particular embodiments shown in the drawings but also comprises any modifications within the scope of the appended claims.
