Abstract

The profile (1) according to the present invention is provided with a longitudinal housing (3) intended to receive an edge of the glass plate (2), the free longitudinal edges of which are located in planes (4, 5) parallel to its bottom (3f) and arranged at different distances from the latter so as to be reciprocally offset: near these free edges, the housing (3) comprises means (6, 8) for anchoring an elastic stopper seal (7) and a fixed elastic window seal (9) which is introduced by force friction between the window (2) and the respective anchoring means (8) provided near the free edge close to the bottom (3f) housing (3).

Description

The present invention relates to a profile for the production of frames

  frames and / or opening panels. In the currently known metal closures, the glass plates or panes are supported on respective reliefs presented by the profiles forming the frame of the frame and are fixed to the frame by a profile.

  additional called "window fixing".

  The window-fixing profiles, normally of quadrangular shape, are structured so that they are rigidly associated by interlocking with respective projections or reliefs presented by the profiles forming the frame proper. There are also provided seals intended to eliminate possible play between the glass and its housing defined by the profiles of the

  frame and those for fixing the glass.

  By a structure of this kind, the assembly of the frame is achieved cutting at 450 the profiles forming the frame, by engaging them reciprocally, cutting transversely the window-fixed profiles according to the dimensions reached by the frame and applying to interlocking the fixed profiles -glass to the frame profiles

by butt overlapping.

  The drawbacks encountered during assembly and the use of closures thus structured are numerous and result from the need to make end cuts of the window-fixing profiles to allow their

  association by interlocking with the frame profiles.

  Indeed, to make correct end-to-end junctions, it is necessary to measure and cut very precisely the window-fixing profiles in order to avoid the formation of gaps between them, which would cause mechanical play and create nests in dust or other signs of lack of cleanliness In order to avoid

  interstices one could think of cutting the fixed profiles-

  glass slightly longer than necessary, but in this case these profiles could be constantly subjected to axial compression stresses and could damage by their opposite ends the

  sections which are perpendicular to them.

  From an aesthetic point of view, clear separations between the frame obtained by means of cuts at 450 and the window-fixing profiles obtained by means of cuts

transverse occur.

  Another drawback is represented by the impossibility of centering the glass plate with respect to the frame because of the need presented by the glass plate to rest on wings or flat terminal reliefs having a thickness much less than that

window-fixing profiles.

  The present invention therefore aims to provide a profile for fixing the glass plates of closures in a practical and rapid manner, alleviating at the same time

  time the disadvantages mentioned above.

  The invention solves the problem addressed by a profile provided with a longitudinal housing intended to receive an edge of the glass plate, the free longitudinal edges of which lie in planes parallel to its bottom and arranged at different distances from the latter. so as to be reciprocally offset: near these free edges the housing comprises means for anchoring an elastic stop gasket and respectively a fixed elastic gasket which is introduced by force friction between the glass and the respective anchoring means provided near the edge

free near the bottom of housing.

  The features and benefits of

  the invention will become more evident from the description

  detailed below, given with reference to the accompanying drawings which represent a preferred but non-limiting embodiment and in which: Figures 1 and 2 illustrate, in cross section, a portion of the frame provided with the set of elements according to the invention and supporting a single glass plate or pane and respectively a double pane,

  that is to say consisting of two glass plates.

  Referring to the appended figures, the profile according to the invention, indicated in 1, has a longitudinal housing 3 intended to receive an edge of a window

respective 2.

  The housing 3 is substantially in the shape of a "C" and

  is obtained along the center line of profile 1.

  An essential characteristic of the profile 1 is that the free longitudinal edges of the housing 3 coinciding with those of the walls 3 a and 3 b defining said housing 3 bilaterally are in planes 4 and 5 parallel to the bottom 3 f of the latter and are arranged at different distances from the same background 3 f so as to be

reciprocally offset.

  As shown in the appended figures, near the free edges of the walls 3 a and 3 b, the housing 3 has means 8 and respectively 6 for anchoring a

  elastic stop gasket 7 and a gasket 9.

  The anchoring means 6, provided near the free edge which is in the plane 5 remote from the bottom 3 f, consist of a housing in the shape of "C" open along a direction perpendicular to the layout plane of the frame which is intended to receive a "T" rib of the

elastic seal 7.

  The seal 7, once introduced into the housing 6, has a flat surface intended to form a stop for the window 2 The means 8 are provided for anchoring the seal 9 which is used for fixing the window and which has a

substantially flat extension.

  The means 8 consist of a coplanar projection with the respective plane 4 and provided, inside the

  housing 3, with an end lug indicated in 8 s.

  The seal 9 is provided, on one of its sides and near its longitudinal edge, with a housing 9 S for receiving the projection 8 and the respective lug 8 S and, on the other side and close to the other longitudinal edge, of a plurality of lips there intended to receive the glass 2 in abutment The lips are inclined relative to the fixed-glass seal 9 and form an angle with the latter whose apex is turned towards the housing 9 s , such as

  shown in the accompanying figures.

  In the embodiment of Figure 2, modified for the use of a double window instead of a single window as shown in Figure 1, the seal 9 extends beyond the housing 9 S by a extension 9 p intended to abut against the bottom 3 f of the housing 3. The section 1 in this case has at the bottom 3 f of the housing 3 a small reinforcing wall 10 against which is intended to abut the extension 9 p of the fixed joint -glass 9 The small reinforcement wall 10 is provided substantially in alignment with the glass plate 2

  for the reason which will be explained later.

  Using a profile 1 and a fixed glass joint 9 structured as described above, the profiles 1 can be cut and the frame assembled so that the planes 4 closest to the bottom 3 f are reciprocally spaced by substantially equal amounts to the transverse dimensions of the glass plate 2 and one can insert

  the stop seals 7 in the respective housings 6.

  Then the glass plate 2 is put in place in the frame until it comes into abutment against the seals 7 After having put the glass plate 2 in place, the glass-fixing seals 9 are introduced between the glass plate 2 and the projection 8 so that the housing 9 S engages with the projection 8 and the lug 8 s During the introduction of the fixed-glass seal 9 the lips 11 fold towards it and ensure its tightness. If the glass plate 2 is of the double pane type, the process will be the same, except that the extension 9 p will abut against the respective small reinforcement wall 10: in order to facilitate this operation The small reinforcement wall 10 can be folded at its upper part towards the housing 6 to form a reception for the extension 9 p The presence of the small reinforcing wall 10, especially near the profile 1

  lower, allows greater rigidity of the fixed joint-

  window 9 so that it can support the higher weight of the double window 2 which, in the absence of the small reinforcing wall 10, would tend to cause sliding

  of the fixed glass seal 9 around the projection 8.

  It is obvious that by using a profile 1 and a glass-fixed joint 9 structured in the manner described, it is possible to overcome all the drawbacks linked to the transverse cuts to be made on the glass-fixed profiles of

known type.

  Not only can the cut of the glass-door seal 9 be carried out at 45 as for the profiles 1, but it can also be carried out with simple and practical cutting means which allow

  faster assembly of the glass 2 to the frame.

  From the aesthetic point of view, the possibility of placing the pane 2 exactly along the center line of the frame appears very advantageous, since to obtain this, it suffices to adequately proportion the dimensions of the planes 4 and 5 and the abutment joints 7 and

window holder 9.

  Another advantage is represented by the possibility of quickly disassembling the glass plate without any problem, given that the removal of the fixed-glass seal 9 does not offer too much difficulty if a pointed instrument is used: in fact, the nature elastic of this joint allows to act directly on it and to remove it

releasing the glass plate 2.

  We must not forget the economic advantage resulting from the elimination of a profile intended to form the blocking element of the glass plate. The invention thus conceived is susceptible of numerous modifications and variants which all fall within the scope of protection thereof. In addition, all the details can be replaced by elements.

technically equivalent.
