Referring to the two figures, the The present invention relates to a door or window frame comprising a fixed frame 10 and at least one swing 20 Sliding mounted on this frame.

The frame comprises at least one stringer 11 of the frame arranged as a raised crossbar, defined according to a direction parallel to the sliding direction 27 of the swing and comprising, at least, a first longitudinal cavity 12, 13 practically "U" shaped, while swinging 20 it comprises a glazing 21 or similar and, on one of its sides 22 with respect to the crossbar 11 of the frame is arranged as a crossbar raised, a stringer beam 23 defined according to one direction parallel to the sliding direction 27 of this swing 20, having this stringer 23 a cross section defined in a plane perpendicular to its direction in general practically rectangular or assimilable to said form, in which a second longitudinal cavity 24 is arranged in the form of "U", the glazing 21 being mounted so that partially penetrates this second longitudinal cavity 24.

The frame also includes first sealing gasket means 30 interposed between the two internal side walls 25, 26 of the two vertical legs of the second longitudinal cavity 24 "U" and the two outer faces 41, 42 of the glazing 21, and a few seconds sealing gasket means 50 interposed between the two outer side walls 43, 44 of the stringer beam 23 and the two inner side walls 45, 46 of the two legs U-shaped vertical cavities 12.

According to an essential characteristic of the invention, as clearly shown in the embodiment  illustrated in the two figures, the first and second means of the seal 30, 50 are constituted respectively by longitudinal lips 61, 62, 63, 64 forming a single block with the stringer of the swing 23, presenting the frame:

-

some longitudinal lips 61, 64 which constitute a few second means of the seal 50 which have flexibility for its elastic deformation in order to perform the function of tightness with the two inner side walls 45, 46 of the two vertical legs of the first "U" shaped cavity 12, Y

-

a layer with a hard surface in contact with the two walls internal sides 45, 46 of the two vertical legs of the first cavity 12 in the form of "U", arranged between the latter and the lips 61, 64 constituting the second means of the gasket of tightness 50, in order to facilitate sliding longitudinal section 23 on the two side walls internal 45, 46.

       \ vskip1.000000 \ baselineskip
    

Longitudinal lips 61 and 64 should have sufficient flexibility for elastic deformation to guarantee the maintenance and guide functions of the crossbar 23 when moving inside the first 12 or the second 13 longitudinal cavity, being able to absorb at the same time deformations of the surface of the inner side walls 45, 46 of the vertical legs that define these cavities, also maintaining contact with these walls mainly in case of differential pressure in either part of the frame or in vibration case. The lips 61, 64 will preferably be in amount of one per outer side wall 43, 44 of the stringer of the swing 23, but they can also be in greater quantity.

In a very preferred way, lips 61, 62, 63, 64 are practically arc-shaped, for example in the form of "comma" or similar, the 65th foot of each arch of the strut beam 23, the curved outer wall 66 being each arc directed advantageously towards the bottom and being suitable to cooperate with the inner wall of the first cavity 12, 13 approaching by elastic deformation by sliding friction against this wall and the curved outer wall 68 of each arc, properly to cooperate with a face exterior 41, 42 of the glazing 21 that gets to adhere elastically against it. The direction towards the bottom of lips 61 and 64, or more specifically of the free end of each of the longitudinal lips 61, 64 located below the lip root allows, in case of overpressure on a face of the glazing, cause an increase in surface pressure inner lip located on the side of the face with overpressure, of such that this lip adheres against the wall in which it It performs the tightness.

The lips 62, 63 that constitute the first sealing gasket means 30 are of a known type and they can comprise for a glazing wall like the represented in figure 2, a lip directed towards the part bottom to improve tightness, and one or two lips directed towards the top to facilitate the placement of the glazing In contrast to lips 61 and 64 that have a dynamic function, lips 62 and 63 have a static function and they remain of conventional conception and constitution.

As mentioned above, to reduce the manufacturing cost of the frame, and propose a monolithic stringer arranged for mounting, lips and stringer beam are made in one piece, by Extrusion example.

The hard surface layer in contact with the two inner side walls 45, 46 of the two legs U-shaped vertical cavities 12 arranged between the latter and the lips 61, 64 that constitute the second means of the seal 50, may be associated advantageously to lips 61 and 64 respectively, and be performed, for example, by co-extrusion according to a known procedure that allows advantageously to obtain a stringer 23 finished in a single block, for example made to from an exclusive plastic material of type TPE (elastomer thermoplastic) and comprising flexible zones of features different mechanics, for the formation of lips 61, 62, 63, 64, more rigid for the constitution of the "U" structure which forms the crossbar 23 itself, and hard for the formation of the superficial layer of lips 61 and 64 in contact with the walls of the fixed element and that performs a sliding function, must therefore have a coefficient of adhesion reduced while remaining flexible in order to follow the movements of the flexible lip.

Alternatively, the beam 23 can be made in a single piece, for example in PCV (polychloride vinyl) that forms the stringer itself and the lips 61, 62, 63, 64 on which a layer of hard plastic material is added to the sliding, for example by gluing, more specifically on the convex part of lips 61 and 64 in contact with the element fixed by sliding. As explained above, the layer added on each lip will remain flexible with the object of being able to follow the elastic deformations of the lip 61 or 64.

Preferably, the frame is designed so that the distance that separates the bottom 19 from the first cavity 12, 13 and face 29 of the stringer member 23 with with respect to this bottom 19 of the first cavity, it is determined so that the swing 20 can be mounted by means of hinges in the first cavity 12, 13, that is as follows. He swing 20 has previously been placed inside frame 10 so that the stringer beam 23 is located as far as possible bottom of the bottom 19 of the frame stringer cavity 11, to allow its lower part not represented in the figures but well known in itself, understand a part of means of hinges that, in this type of swing are made of wheels  that can be placed on the rails with which the wheels are destined to cooperate, then the swing is moved along its plane so that the crossbar moves away from the swing 23 and bottom 19 and allows the wheels to be placed on The rails.

As mentioned earlier, a frame of this type comprises at least two hinges sliders 20, 220, figure 2. In this case, the frame stringer 11 comprises two first longitudinal cavities 12, 13 juxtaposed and parallel to each other, the interior of which is suitable for guiding the two stringers respectively 23, 223 of the two hinges 20, 220.

Stringer 23 described above finds a very preferred application as a raised crossbar of a swing sliding, as shown in figures 1 and 2, and a this end may be connected to all types of uprights known verticals for sliding hinges, for example, such as shown in figure 3 for connection with an upright central vertical 31, or in figure 4 for connection with a vertical upright 32 side intended to come into contact with a vertical amount of fixed frame. The connection of the crossbar 23 with one or the other of the vertical uprights 31, 32 will be made in a manner advantageous by means of a connection plate, 33, 34 as it is depicted in figures 3 and 4, embedded in the end of the beam 23, for example the rigid connection between the connecting piece 33, 34 and the crossbar by means of a screw 35, 36. Each connection piece 33, 34 comprises an interconnection appropriate for connection with its associated vertical upright, also for the purpose of a rigid connection, for example, by screw and / or recess means.

Advantageously, both from the point of view of sonic and thermal insulation, as from the manufacturing cost reduction, frame 11 stringer is formed by the assembly of three profiles, two profiles first and second 71 and 72 and a third profile 73 located between them and that includes means of solidarity 74 with the two profiles first and second to join them in solidarity, comprising this third profile 73 also a wall 75 protruding that separates said two first cavities 12, 13, for example a wall 75 provided with alveoli as shown in figure 2 to improve the thermal isolation. Preferably, the third profile 73 is made of a thermally insulating material such as polyamide or analogous, especially fiber loaded polyamide, for example of glass fibers

As illustrated more particularly in Figure 2, the means of solidarity 74 of the third profile 73 with the first and second profiles 71, 72 to join them together solidarity, they are constituted at least by two pins 78, 79 solidarity respectively of the first and second profiles 71, 72 by one of the following two means: crimped or stapled.
