Abstract

Description

Section for door and window frames and frames thus obtained.

The present invention relates to door and window frames or fixtures and more particularly to an improved section for the construction of said frames. A "frame" or "fixture" is normally understood as meaning an assembly composed of a stationary framework or body fixed along three or four edges (two vertical edges, one horizontal top edge and one horizontal bottom edge only in the case of a window) of the opening which is to be closed and at least one wing hinged along its edge with the frame and rotatable about a vertical axis. In some cases, such as for example so-called hopper frame windows, the wing is hinged along its bottom horizontal edge and may be only partly opened.

The wing is in turn also formed by a perimetral framework which is closed in its central part by one or .more panels made of different materials such as wood, glass or plastic. Usually both the door or window frame and the framework of the wings consists of straight elements which have a specific profiled shape corresponding to particular functional requirements.

Considering first of all the perimetral body or framework, it comprises a section (made of wood, metal, in particular aluminium, or plastic) the outer side of which, i.e. the side facing the wall, is in abutment on and is fixed to a frame support, while the opposite side, i.e. the inner side, facing the wing and co-operating with the section forming the framework of the wing, has given recesses and shaped parts with specific functions.

In particular, the aforementioned inner side is provided with a flat-bottomed groove of suitable width able to seat the so-called "fittings", namely the mechanical devices both for operating and for closing and locking the wing, co-operating obviously with other mechanical components fixed to the side located opposite the above mentioned section forming the body. The latter is in turn provided with a slot or groove of a certain depth used to seat a flexible sealing gasket (made of resilient material). Finally, profiles are provided of a particular shape, having the function of a "drip stop" for preventing the infiltration of water, in particular in the case of heavy or wind-swept rain.

Therefore, in conventional frames known hitherto, at least two and preferably three types of different sections, namely with different shapes for the surfaces which during final framework are located opposite each other, are used. This differentiation involves, as may be easily understood, complications both during assembly and in terms of storage requirements for the supplies of sections.

It is obvious that, if it were possible to use a single section for construction of the entire fixture and more precisely for construction of both the wing framework and the stationary body, considerable advantages would be achieved from an industrial point of view.

This is precisely the object of the present invention, which is achieved by means of a section having two opposite active sides, the first of which is provided with a groove of suitable width and depth for receiving the edge of a glass pane, while the opposite side has a particular shape comprising said first slot of a width and a depth suitable for mounting the usual fittings, a second groove able to seat a sealing gasket of type which is usual in these frames and an extended projection such as to form the usual stop or contact surface against a stationary upright.

As will emerge clearly from the detailed description which follows of a preferred embodiment of the present invention, the section defined above may be used equally well both for construction of the stationary body or framework of the door or window and for construction of the wing framework, provided that the associated sections of both the stationary and the wing framework are oriented such that the side having the aforementioned shape is in front of the same side of the other component. In other words, since the section forming the stationary body or framework cooperates with the section forming the wing framework, these two sections in the case of the present invention are formed by a single section, and the said first side thereof, namely that provided with a groove of suitable width and depth for receiving the edge of a glass pane, is directed towards the outside, while the said second side with said special shaped profile is directed towards the inside and therefore so as to face the identical side, with a special shaped profile, of the other opposite section.

The particular features and advantages of the present invention will emerge more clearly from the following description of a preferred embodiment provided with reference to the accompanying drawings, it being understood that conceptually and mechanically equivalent modifications and variations are possible and may be envisaged without departing from the scope of the invention.

In the drawings:

Figure 1 shows a partial cross-sectional view of a fixture (wing and stationary body) according to the state of art;

Figure 2 shows a cross-sectional view of the section according to the present invention;

Figure 3 shows a view of a construction which is similar to that of Figure 1 and in which the section according to Fig. 2 is used;

Figures 4 and 5 are cross-sectional views which show particular embodiments of i frames according to the invention; and

Figure 6 is a partial perspective view of a portion of a section according to the invention for the use in a frame, illustrating a constructional detail. With reference first of all to Figure 1, this shows, as already mentioned, a frame or fixture of the known type comprising a section 10 forming part of the stationary body or framework of the window and a section 12 forming the perimetral framework of the wing

(not shown).

The section 10 is fixed, along the side 14, to a frame support (not shown) which is in turn anchored to the wall, while- on the opposite side 16 it is provided with a slot or groove 18 intended to a receive a sealing gasket 20.

A second groove or slot 22 performs the usual function of a "drip stop" which is known per se.

If we now consider the section 12, it is provided on the outer side 24 with a flat- bottomed groove 26 (which in the embodiment is defined by a projection 28 and by a strip

30), the groove 26 having a width and a depth such as to seat the edge of a glass pane (not shown). The side 32 of the section 12 is provided with a recess 34 of standardised dimensions for seating the already mentioned fittings for operating, closing and locking the wing, obviously making use of the gap 36 thus defined between the two sections 10 and 12 where also mutually mating and engaging lugs 38 and 40 are respectively provided.

If we now consider the section according to the present invention, generally indicated by the reference number 42, its cross-section is shown in Figure 2, to comprise two sides, 44 and 46 respectively.

The side 44, substantially corresponding to the side 24 of the section 12, is provided with a groove or slot 48 of a width and a depth such as to seat the edge of a glass pane (when the section is used to form the framework of a wing) or for anchoring to the frame support (not shown).

In turn the opposite side 46 is provided with a first recess or groove 52, of suitable dimensions for framework the already mentioned fittings, as well as a groove or slot 50 intended to seat the usual lip seal.

Figure 3, which relates to the simplest example of a fixture stationary framework or body and an associated wing, shows, in cross-section, the relative position of the two sections respectively forming the stationary framework or body of the fixture and the perimetral framework of the wing.

For the sake of clarity, the parts of the section forming the wing framework are indicated by the reference numbers in Figure 2 plus the suffix A and the parts of the section forming the window framework are indicated by the reference numbers in Figure 2 plus the suffix B.

From Figure 3 it can be readily understood how a section with the same shape can be used to form the entire fixture.

In particular it can be appreciated how the section 42B, which performs the functions of the section 10 according to Fig. 1, is operationally combined with the section 42 A, which in turn performs the functions of the section 12 according to Fig. 1, without detriment to the functionality and without introduction of further means.

In fact, again with reference to Fig. 3, it can be seen that the section 42 A, forming the perimetral framework of the wing, receives inside the slot or groove 48A the edge of the glass pane (shown by way of example as cavity glass) and the usual fittings are mounted inside the slot or groove 52A thereof. In the embodiment shown this latter groove or slot has a depth greater than the slot 34 formed in the section 12 forming the wing frame in Fig. 1. However, this is a difference in the region of one millimetre which may be compensated for either by increasing the thickness of the aforementioned fitting or by increasing the depth of this slot with a shim of the necessary thickness. In turn the section 42B which forms the stationary framework of the fixture seats inside the groove 50B the usual sealing gasket, while the slot or groove 52B, corresponding to the groove or slot 52A of the wing section 42A, performs the function of a drip stop in particular for the section portion forming the bottom horizontal section of the window frame. The reference number 56 denotes the usual external sealing hinge between the wing section 42A and the frame section 42B.

It can be seen in Figure 3 that the two sections 42A and 42B are shown as the assembly of three strips of wood, but it is obvious that they may also be made of material in block form by suitably machining the two opposite sides 46A and 46B.

Alternatively, these sections may be made by means of extrusion from plastic or aluminium, in which case they are preferably hollow and provided with optional internal stiffening ribs. If we now consider the illustration in Figure 4, this shows the arrangement of the sections according to the invention in the case of a two-wing window. More particularly, it shows the configuration of the central upright of the window on which the ends of the two wings are in abutment.

For the sake of simplicity and clarity of illustration the sections of the two wings and their components are indicated by the same numbers as used in Fig. 3. In particular it can be seen that the two wing sections 42 A interact with a central upright 58 having two opposite sides 60B which are shaped in the same manner as the side 46B of the window framework in Fig. 3. Therefore each of them is provided with a slot or groove 50B and a slot 52B having exactly the same functions performed in the case of the section 42B in Fig. 3. ₍ -

In other words the section 58 is equivalent to two halves of the section 42B, the part of which comprising the side 46B has been retained.

The other two sides 62 and 64 of the section 58 are instead shaped so as to cooperate with the corresponding lugs of the sections 42 A. In this case the reference number 66 denotes the handle for operating the fittings and moving the wing. i j

Considering finally Fig. 5, this shows a variation of the embodiment according to Figure 4, in which one of the two leaves is fixed.

In this case the two sections 42A remain unchanged and therefore their components retain the reference numbers according to Fig. 4, while there is a modification to the central upright 68 which has one side 68B still identical in terms of shape to the side 60B of the section 58 in Fig. 4 as well as to the side 46B in Fig. 3. Therefore it is provided with the slot 50B for seating the internal seal and the slot 52B for seating the fittings.

The side 68 A of the central section or upright 68, however, is shaped so as to allow

1 joining of the side 46 A of the section 42A, except for small residual empty spaces corresponding to the bottom of the slots 52A and 50A, which otherwise would require more laborious machining of the said side 68 A with projections intended to be combined with the abovementioned bottom parts or empty residual spaces. Using the same reference numbers as in Figure 2, it can be clearly seen in Figure 6 how a fitting, generally indicated by the reference number 74, is seated inside the slot 52 so as to interact with the other fittings which may be positioned in the same slot or in a facing slot. In this case this part 74 has, as already mentioned, a thickness increased by about 1 millimetre, but this increase may be avoided (using standardised fittings if necessary) by arranging between the bottom of the part 74 and the adjacent bottom of the slot 52 a thin metal shim of a correspondig thickness.

The invention has been described with reference to a window, but it is understood that it is also applicable both to door frames (in which case it is obvious that the fixture framework portion corresponding to the door sill may be omitted) and to furniture doors (in which case obviously the dimensions of the sections may vary and in particular for example the slot for seating the fittings may be adapted to the specific requirements of the furniture, as may also in this case the slot for seating the seals be adapted to more specific requirements).

In this latter case it is obvious that "furniture doors" is also understood as referring to doors of household appliances such as, for example, refrigerator cabinets.
