Description

Bolt for window leaf or similar.

The invention relates to a leaf bolt window, balcony door or similar, according to the preamble of claim 1.

The present invention relates to the scope of the construction hardware and refers in particular to locks planned capable of being embedded in a slot in the renewal of a sheet, in particular, of a two-leaf window.

For this purpose, in the case of a window two mounted blades articulated in a frame devoid of mullion center, one of these sheets, service call, is provided with a locking hardware, very often a failure, while the renewal of its front stile covers the renewal of the front upright corresponding to the other sheet, fixed call Under such conditions, the latter may be ajar only after unlocking and turning the sheet service.

In fact, the fixed blade is also called that in the extent to which blocking means are usually associated in the form of one or more locks that are positioned in the revalidation of its front stile. Such locks are provided with a bar from which one end is likely to appear outgoing, according to the case, at the upper end or at the lower end of this front upright of the blade, to cooperate with a strike arranged in correspondence on the frame crossbar. In effect, this or these bolts keep this fixed blade closed against this frame, even after unlocking it associated with the service sheet.

Going back to these bolts, the one mentioned above bar is positioned inside a groove that this amount Fixed blade front behaves in the renvalso. In fact bliss bar moves behind a guard at the front of the which is a control body that allows to act on said bar to carry the latter, as the case may be, in the position of Lock or unlock. This control body may appear in the form of a slide mounted axially movable in the part front of the guard, while being in solidarity with the bar that moves behind the latter. Connection media connect this sliding to said bar through one or more openings elongated in this guard that allow to reach the position of lock and, conversely, unlock.

This control body can also be presented in the form of a lever rotatably mounted on the part front of the guard and that, after blocking, retracts and position in the prolongation of the latter.

In some cases, this lock is capable of being controlled by means of the locking hardware, in particular, the failure, from which the service sheet is provided. In such a case, the control body is provided capable of cooperating, with a closed window, with a drag finger that the front upright of this service sheet entails in the renewal. This drag finger is capable of being operated by a maneuver bar corresponding to said
I failed

Whatever your embodiment, these locks carry means that support, while leaving it free in sliding according to a certain race, the bar with respect to the guard. These means of solidarity do not only require the realization of specific mechanizations, both at the level of saves as from the bar, but also generate, during the manufacture of these bolts, assembly operations that can be call constringent.

On the other hand, they intervene very often at the level of the ends of the guard, so that these locks are not Adjustable in length by a simple cut.

It will also be noted that, due to the progressive evolution of carpentry, particularly profiles both Aluminum as PVC, numerous references of locks appear in the manufacturers catalogs, whose stock management is so complicated. In addition and as we have already indicated above, the same design of these bolts according to the state of the art limits its application, because the dimensional constraints that result of the same allow its assembly only on certain sheets whose size (maximum / minimum) is adequate.

In addition, the games in the renvalso, be between the sheet and frame, service sheet and fixed sheet or also between a sheet and the mullion of a window frame or the like are variables and tend to decrease rather than locks acquaintances often pose a volume problem.

Thus, it is known, for example of the document FR-2,744,479 a bolt that has a bar that extends behind a guard that has a rectangular light from which emerges a free end folded into a square corresponding to the bar and constituting substantially a control body that allows acting on said bar. Under the end of the guard against which it is likely to appear protruding the corresponding end of the bar is provided a sleeve designed to ensure the guidance and maintenance of this last. You will also notice that this connection from the bar to the guard with relative mobility is ensured here, so complementary, through a T-shaped rivet that extends behind said guard and passing through an elongated light in the bar.

Obviously, it is understood that the realization of such a bolt requires the execution of several operations of multi-piece assembly

In fact, it follows from the state of the art that these locks systematically use a sleeve to keep and guide the bar, at least at the end of the guard with respect to which it extends in the locked position. This sleeve, which constitutes an additional piece, requires of course a specific assembly operation.

As in the design of a bolt according to the document FR-2,744,479, it is common to ensure a indexing the locked and unlocked position of the bar by adding, here too, an additional piece that does not This design of this bolt is more complicated than anything else.

The present invention aims, by consequently, being able to provide a solution for these different problems through a bolt that presents, in particular, the advantage of being of a very simple design, which requires a minimum of manufacturing operations and whose assembly is the easiest, in addition to pretending to be easily adaptable in size to allow its application in the most constringent conditions. This bolt according to the invention is also intended to be of a simplified implementation, both alone and in connection with others hardware on the same sheet and / or on an adjacent sheet, even a frame. In particular, this simplicity of design allows contemplate that such a bolt intervenes as an extension as in the case of an application, for example, of type Failed-lock.

It is also known, from the document DE-B-1 075 000, a bolt that It comprises a sliding bar mounted behind a guard. The bar involves a first end that may appear outgoing with respect to a corresponding end of the guard, to define a blocking organ

Indeed, at this end, said guard is bent square, so that it forms an elbow in which it is provided a passage opening of said bar.

The latter also involves a second end folded so that it passes through an opening in the guard and define an accessible control organ on the front face of this last.

To this end, the invention relates to a bolt for window leaf, balcony window or similar, which involves a guards behind which extends a bar comprising, by a On the other hand, an end that may be protruding from a corresponding end of said guard to define an organ of lock capable of cooperating with a strike and, on the other hand, a opposite end bent so that it passes through an opening in the guard and define, on the one hand, an accessible control body on the front of the latter and, on the other hand, first maintenance and guidance means, characterized in that said guard it means defined maintenance and guidance means by embedding and / or trimming and / or folding of the latter, no located at the end with respect to which it is susceptible to the end of the bar is protruding, these means being planned secondary maintenance and guidance capable of cooperating with complementary secondary maintenance and guidance means, also defined by embedding and / or trimming and / or folding of the bar, to support the latter with said guardian with a relative axial mobility

The advantages that result from this invention consist in that the bolt according to the present invention It turns out to be of a simpler design, since it is defined for two pieces that can be made by means of a sausage operation - even bending trimming. In addition, in a preferred embodiment, these parts are defined for manual assembly This lock is also from an application almost universal that allows, in particular, that the manufacturer standardize your product range, therefore optimize management of your stocks.

The present invention will be better understood by the reading the description that follows and which refers to examples of embodiment illustrated in the accompanying drawings.

While Figure 11 illustrates so schematic and in perspective the clip that keeps it behaves on its rear face as an additional connection between That guard and the bolt bar.

The present invention relates to a bolt whose different embodiments are illustrated in the figures 1 to 11 of the attached drawings.

Usually, such lock 1 is provided capable of being embedded in a slot in the renvalso of a sheet of window, balcony window or similar.

Thus, you will find its usefulness in the case of windows of two leaves whose frame is devoid of center mullion. In such conditions, it is positioned at the upper or lower end of a slot in the front upright corresponding to the fixed call sheet, as opposed to the call service sheet provided with the blocking hardware, in particular, the failure or lock that such a window failed.

Thus, this bolt 1 has a bar 2A, 2B, 2C, 2D that extends behind a guard 3A, 3B, 3C, 3D and the which one end 4 is capable of being outgoing with respect to the corresponding end 5 of the latter.

In particular, through this design and in the case In an embodiment as described above, this end 4 of bar 2A, 2B, 2C, 2D is, in locked position, able to appear outgoing with respect to the upper end or bottom of the front upright corresponding to the fixed blade, for cooperate with a locksmith arranged in correspondence in the window frame. Upside down, in unlocked position, said bar 2A, 2B, 2C, 2D retracts behind this guard 3A, 3B, 3C, 3D

It is possible to act on the bar 2A, 2B, 2C, 2D to move from this locked position to the unlocked position, or vice versa, thanks to a control body 6A, 6B, 6C, 6D defined accessible on the front face 7 of said guard 3A, 3B, 3C, 3D

The latter involves an opening 10A, 10B, 10C, 10D passing through one end 15A, 15B, 15C, 15D folded from the bar 2A, 2B, 2C, 2D and that substantially defines this organ of control 6A, 6B, 6C, 6D accessible on the front face 7 of said Save 3A, 3B, 3C. In fact, this opening 10A, 10B, 10C, 10D in the keep 3A, 3B, 3C, 3D and the 15A, 15B, 15C, 15D end folded from the 2A, 2B, 2C, 2D bar are designed capable of defining first maintenance and guidance means 8A, 8B, 8C, 8D to support said bar 2A, 2B, 2C, 2D of said guard 3A, 3B, 3C, 3D with a relative axial mobility

Said guard 3A, 3C, 3D involves means of secondary maintenance and guidance 9A, 9C, 9D defined by sausage and / or trimming and / or folding of the latter and planned capable to cooperate with secondary maintenance and guidance Complementary 9'A, 9'C, 9'D, also defined by inlay and / or trimming and / or bending of bar 2A, 2C, 2D, to support the latter with said guard 3A, 3C, 3D, also with mobility relative axial

We will refer in particular to figures 1 and 2 corresponding to a first embodiment of the bolt 1 according to the invention.

Thus, in this case, the opening 10A is defined. at guard 3A level by a rectangular light, in particular proximity of its end 11 good looking at that 5 relative to which it is The bar 2A may be protruding.

In addition, the means of maintenance and guidance secondary 9A are constituted, at this end 11 of said guard 3A, by a retention handle 12 provided with an opening 13 and defined by embedding and / or trimming and / or folding, which extends above the front face 7 of said guard 3A. The opening 13 is section adjusted to that of bar 2A. The latter involves, also, as secondary maintenance and guidance means complementary 9'A, an end portion 14 that forms a recess regarding your main plan and that extends beyond your bent end 15A passing through the opening 10A in the guard 3A. Thus, in the mounted position of said bar 2A, its free end 15, opposite that 4 that forms a blocking organ, is inserted into this opening 13 of the retention handle 12.

On the other hand, at the level of this portion of end 14 of bar 2A, which emerges on the front face 7 of this guard 3A, a shoulder 16 is provided that completes the organ of control 6A defined by said bent end.

Along the bar 2A, they are also verified elongated openings 17 facing holes 18 in the 3A guard for the passage of fixing screws that allow solidarity bolt 1 with carpentry.

It will be noted that, according to the invention, this bolt 1 may be provided with indexing means 19 that allow locate the position of the bar 2A, 2B, 2C, 2D with respect to the save 3A, 3B, 3C, 3D, that in particular in locked position and Unlock

In substance, in the embodiment corresponding to figures 1 and 2, these indexing means 19 consist of a shoulder 20 provided at the level of the bar 2A in front of Save it 3A. In addition, the latter involves accommodation or perforations 21, 22 with which it is able to match this I highlight 20, precisely in these locked positions and unlock Obviously, you could imagine a reverse design that it consists of providing the guard of a highlight, behaving the bar Then the housings or perforations.

In the framework of the embodiment corresponding to figures 3 to 5, the first means of maintenance and guidance 8B to support said bar 2B with said 3B guard with relative axial mobility consist, here too, in an opening 10B, rectangular in shape, at the level of guard 3B, and a free end 15B, square bent, of bar 2B, of mode capable of passing through the opening 10B and of constituting substantially, the control body 6B accessible in the face front 7 of guard 3B.

In the same inventive concept, the means of 9B secondary maintenance and guidance are defined by a rivet in the form of T 23 planned capable of cooperating with means of 9'B complementary secondary maintenance and guidance in the form of an elongated light 24B provided in bar 2B, to support this last with said guard 3B with relative axial mobility.

Thus, this rivet 23, whose head 25 is of a diameter greater than the width of the elongated light 24B, ensures the sliding mode maintenance of the 2B bar behind the guard 3B.

As in the embodiment above, at the level of this bar 2B one or several other elongated openings 17 facing holes 18 in the 3B guard for the passage of fixing screws.

As for indexing means 19, these they are associated with the opening 10B in the guard 3B, on the one hand, and at the free end 15B, square bent, of bar 2B, by other side.

In particular, said indexing means 19 consist, at the level of this opening 10B, in end portions 26, 27 adjusted to the width of the bar 2B and separated by a median portion 28 that forms a narrowing, therefore of width less than that of this bar 2B.

The 15B square bent end of this bar 2B behaves, in turn and as visible in particular in the Figure 5, cuts 29 at the level of its lateral edges 30, 31. Thus, at the height of these cuts 29, this end bent square 15B of bar 2B has a width 32 adjusted to the width of the median portion 28 of the light 10B. Starting on both sides of these cuts 29, this square bent end 15B of the bar 2B retains a width equal to that of the latter, that is, a width adjusted to the passage of the end portions 26, 27, of this opening 10B. Therefore, when said cuts 29 are placed  facing the lateral edges 33, 34 of this median portion 28, this curved end in square 15B of bar 2B can move freely along the light 10B to pass from the locked position to unlocked position.

However, and as you can see in the Figure 5, the cuts 29 have the particularity of conferring this square bent end 15B a form of H, of which a lower horizontal branch 35 of width adjusted to that of the bar 2B is inserted in the opening 10B, at the height of its parts extreme 26, 27. Under such conditions, it is conceived that it is necessary exert pressure on this free end 15B of bar 2B to release it, by elastic deformation of the latter, of this horizontal branch 35 of the H of said opening 10B and in order, first, of presenting cuts 29 in the extension of the edges laterals 33, 34 of the median portion 28 and to be able to pass from one locked position of bar 2B to its unlocked position, and at reverse.

Under the action of bar 2B that returns to elastically adopt its initial form and after having reached a another of these positions, said horizontal branch 35 of the H corresponding to this free end 15B of bar 2B returns to inserted into a widened end portion 26, 27 of the opening 10B, thus immobilizing in translation, the bar 2B with respect to the save 3B.

Figures 6 and 7 illustrate an embodiment that differs from that corresponding to Figures 1 and 2 in that the secondary maintenance and guiding means 9C are defined by a T-shaped hook 36 made by embedding - trimming the guard 3C and extending below the latter to cooperate with an elongated light 24C cut in the bar 2C and corresponding to the complementary secondary maintenance and guidance means
9'C.

Thus, this hook 36 has an axial branch 37 extending under guard 3C and of width adjusted to the elongated width 24C in bar 2C, allowing the latter move freely from your locked position to your position unlocked On the other hand, this T-shaped hook 36 ends by a transverse branch 38 that extends substantially in parallel under guard 3C. On the other hand, although it has a transverse length 39 greater than the width of said elongated light 24C, its width 40, seen in the axial direction of the saves 3C, is defined less than or equal to this width of said light elongated 24C.

This feature allows to fit through this elongated light 24C the bar 2C on the T-shaped hook 36 positioning this 2C bar first substantially perpendicular to the axis of guard 3C. Finally, after having passed the transverse branch 38 of this hook 36 through the light elongated 24C on bar 2C, it can be rotated around its axial branch 37, to be presented on guard shaft 3C. In this moment, its free end bent in square 15C, of identical characteristics to free end 15B of bar 2B corresponding to the embodiment of figures 3 to 5, may insert into the opening 10C of this guard 3C.

In the framework of the embodiment corresponding to figures 8 to 11 this problem is solved replacing such a T-shaped hook 36, as means of 9D secondary maintenance and guidance by at least one clip of hooked 41 which also extends under the 3D guard and over which adapts by pressure the 2D bar through its light elongated 24D that constitutes the means of maintenance and guidance complementary secondary 9'D.

In particular, this hook clip 41 results of an inlay trimming operation of said 3D guard. It consists of a tongue 42 cut in the longitudinal axis of this last. It is pushed so that it stands out under this 3D guard and it has a transverse width 43 smaller than the width 44 of the 24D light, to allow the insertion of the 2D bar on this tab 42. The latter also has a distance 45 from the rear face of said 3D guard corresponding at least to the thickness 46 of the 2D bar, lateral retention nails 46 that confer this tab 42, at this level, a width 47 greater than that 44 of said light 24D in the 2D bar. Thus, the lace of the latter, to through its light 24D, in this tab 42 it is obtained with a slight force, presenting the lateral branches 48, 49 of the 3D bar which delimits said light 24D a sufficient elasticity to pass beyond retention nails 46. Preferably, the latter they are chamfered on their 50 side in front of the 3D guard, so that this lace is provided, while, on the opposite side, they form a recess to prevent the 2D bar from falling out.

Obviously, this hook clip 41 can adopt other embodiments. In particular it can be defined in the form of an independent piece capable of being in solidarity with the guard by riveting, insertion with force or Similary.

As is clear from the description that precedes, the present invention leads to design locks of the simpler, which obviously reduces its manufacturing cost, but also that of its assembly and its assembly in a carpentry.
