FR2877378A1 - Lock for sliding window, has mechanical units entirely situated in plane parallel to glazing plane and metallic box that contains mechanical units and insulating units which are arranged between two metallic box and box - Google Patents

Abstract

The lock has mechanical units (7) entirely situated in a plane parallel to a glazing plane and a metallic box (8). The metallic box contains the mechanical units and insulating units (13, 14) which are arranged between the box and a box (12). The box (12) is situated symmetrically on a side of the glazing plane and delimits zones (5, 6) breaking thermal bridges in the lock.

Description

2877378 1

    Position of the lock on all sliding chassis allowing, at this level, to eliminate the thermal bridges and improving the aesthetics.

  It is found that the lock for sliding frame, whether it is without key or with key, is placed in the plane of the glazing.

  As a result, it creates, by itself, in said frame, a median zone which constitutes a thermal bridge, the supports of the mechanical members of said lock being often contained between metal plates located on either side of the glazing, to ensure a certain security of the closure.

  These metal plates are themselves equipped, themselves, plastic junction elements between the two faces, to create, at this level, a thermal bridge break on both sides of the lock, in the plane of the glazing, but we can not avoid the thermal bridge created by the mechanical parts of the lock itself located between these two areas.

  The present invention therefore aims to remove this thermal bridge, at the same time as providing an improvement in terms of aesthetics. This is achieved by placing the lock in a plane parallel to the glazing plane.

  More precisely according to the invention, the position of the lock on all sliding frames is remarkable in that the mechanical elements of said lock are entirely located in a plane parallel to the glazing plane and the box containing them.

  This new situation of the mechanical elements of the lock located below the glazing has, as a first advantage, as will be seen, to prevent the lock from constituting a thermal bridge by itself, and, as another advantage, to change the aesthetics of the panel at its junction significantly reducing the metal surface that previously occupied an important place.

  Indeed, the trunk containing said mechanical elements is itself equipped with insulating elements which, stretched between the trunk which contains said mechanical elements and the trunk located symmetrically, for aesthetics, on the other side of the pane, delimit the areas and thermal break.

  The invention is further characterized by the details which will emerge from the description which will be given, in which: - Figure 1 is a view of the currently used assembly, the invention is an improvement.

  - Figure 2 is a view showing the lock positioned in a plane parallel to the glazing, said lock being provided with a key mechanism.

  - Figure 3 is a view showing the lock positioned in a plane parallel to the glazing, and having no key mechanism.

  As represented in FIG. 1, the lock 1 being placed in the plane of the glazing unit, it can be seen that it creates a central zone 2 which inevitably constitutes a thermal bridge, even if the metal plates 3 and 4 which support it comprise between them the zones 5. and 6 ensuring a thermal break, on either side of said lock, in the plane of the glazing.

  The improvement provided by the invention, and object of Figure 2, shows that the position of the lock in a plane parallel to the glazing plane allows to remove any thermal bridge at this level.

  Zones 5 and 6 of thermal break remain between the metal plates supporting the mechanical elements 7 of the lock. And the metal case 8, containing these mechanical elements and the control button, are, of the same fact, thermally insulated.

  It even becomes possible to eliminate the direct passage of air at the level of the hiatus formed at the junction of the two glazed panels by installing a seal 9 brush or elastic type (see Figure 3), whatever the form.

  Independently of the important technical advantages provided by this new assembly, the aesthetics is also improved by the fact that the slightest bulk of the visible metal elements in the center of the chassis, their size passing from the 147 mm of the conventional assembly to 88 mm the horizontal plane for the assembly described above.

  And, if the thermal advantages are perfectly maintained when the lock does not have a lock (Fig. 3), the aesthetic advantage is, in turn, increased in this case, because it allows to locate the control button in the vertical plane of the junction of the two glazed panels (Fig. 3), further reducing the visible bulk, and reducing it to 76 mm in the horizontal plane.

  In summary, the mechanical elements 7 of said lock are fully positioned in a plane parallel to the plane of the glazing, and the trunk 8 containing them.

  So that the trunk 8 containing said mechanical elements 7 may itself be equipped with plastic elements of any kind such as insulators 13 and 14 which, stretched between the trunk 8 containing said mechanical elements and the trunk 12 situated symmetrically, for aesthetics, on the other side of the glazing, delimit zones 5 and 6 of thermal break and the new arrangement thus adopted for the position of the lock in a plane parallel to the glazing plane, creates a break thermal bridging up to the junction area of the two sliding panels by introducing brush seals 9 (see Fig. 2) or by introducing an elastic seal 9 (see Fig. 3).

  And this is made possible, that the lock 15, placed in a plane parallel to the plane of the glazing, is provided with a locking device (FIG 2), or that it is provided with a closure device without key (Fig. 3).
