Description

The present invention relates to a fitting of lock for sliding door, window or the like.

We know many types of hardware lock for sliding door (for example FR-A-2 590 309 and EP-A-0 389 447). We must resolve for each type of fitting the problem of fixing the fitting on the opening in an inviolable manner from outside the opening.

We know fittings formed by two shells arranged respectively on one and the other face of the opening. To avoid dismantling the fitting from the outside, the outer shell includes tubular projections projecting toward the interior and internally threaded in which are screwed screws introduced through a hole in the inner shell. These fittings are expensive.

We also know fittings of sliding door lock comprising a single shell introduced into a light provided on the front face of the interior side of the amount of the opening. To fix this shell on the transverse edges of this light, said transverse edges are pinched between an outer shell cleanness plate covering the edges of the light and a body of fixing introduced into the light with the shell and brought closer to the outer plate by means of a screw crossing said plate.

A sliding assembly comprising a bolt and a operating element of the sliding assembly is introduced into the shell before the introduction of the shell in the light of the opening.

Such fittings are satisfactory both the reliability and maneuverability plan that on the security plan for locking in relation to attacks from the outside. In terms of aesthetics, the outer plate completely covers the light of opening it and masking this light. She can have a peripheral contour of any shape and style. However, such fittings are relatively complex and expensive.

The object of the present invention is to remedy to the drawbacks of fittings of the aforementioned type, and to propose a fitting of this type which is particularly simple and economical while remaining perfectly reliable and meeting all criteria security against assaults.

Locking fitting for sash sliding door covered by the present invention comprises a sliding assembly movable in the direction longitudinal of a longitudinal light formed on a wall on the inner side of the opening between a locked position and an unlocked position, and comprising an operating member making it possible to control the movement of the sliding assembly from the outer face of said wall, the fitting also comprising two fixing members comprising means for respectively fixing the fitting of locking at the transverse edges of the light.

According to the present invention, the fitting of the aforementioned type is characterized in that it comprises a outer plate adapted to cover the edges of said light and being an integral part of the sliding assembly, and in that the two attachment include means adapted to receive additional means of the outer plate and cooperate with these complementary means so as to guide the sliding assembly during its movements by sliding relative to said wall and to the hold against this wall.

We thus removed the case or shell known fittings, by simplifying the structure of the fitting and the means for fixing said fitting on the sash.

The sliding assembly including the plate outer thus slides in relation to the wall of opening it in the longitudinal direction of the light. The sliding assembly is guided by the fixing in these sliding movements relative to the wall of the door and is held by these organs against this wall. The fasteners are adapted to receive additional resources from the plate exterior to allow fitting of the fitting on the light of the opening.

This gives a particularly structure simple and economical, which is also reliable due to the fact of the small number of components making up this structure.

According to a preferred version of this invention, at least one of the fasteners has means for blocking the outer plate in its locked position, and means for unlock said outer plate to move it away from this locked position.

Other features and advantages of the present invention will appear in the description detailed below.

In the embodiment shown in the figures, the 1 locking device for sliding door 2 door, window or the like, includes a set sliding 10 movable in the longitudinal direction 11 a longitudinal light 8 formed on a wall 9 which is the front side, on the inside, of the amount of the opening 2, between a locked position, shown in Figures 1 and 3, and a position unlocked, shown in Figures 4, 7 and 8, and comprising a recess forming an operating member 12 which controls the movement of the assembly sliding 10 from the outer face 13 of the wall 9.

The fitting 1 also includes two fixing 14, 15 comprising means for fixing the fitting 1 respectively at the transverse edges 6, 7 light 8.

According to the present invention, the fitting 1 has an outer cleanliness plate 3 adapted to cover the longitudinal edges 4, 5 and the edges transverse 6, 7 of said light 8, and forming part integral with the sliding assembly 10, and the members fixing 14, 15 include means adapted to receive additional resources from the plate 3 and cooperate with these means complementary to guide the outer plate 3 when moving by sliding relative to the wall 9 and to hold it against this wall 9.

Conventionally, the recess forming an organ 12 is a cavity extending towards the interior, realized in some way, by example by molding or by stamping, and delimiting in the outer plate 3 a light 16 in which one can insert fingers to rest on bottom 17 of this cavity in order to move the assembly sliding 10 formed by the operating member 12 and the outer plate 3 in the longitudinal direction 11, either in the locking direction 18, to the right at Figures 1 to 4, either in the opposite direction of unlocking.

Conventionally, the sliding assembly 10 carries a bolt holder shown diagrammatically at 19 in FIG. 1 and placed, in this example at the end of the sliding assembly 10 in the locking direction 18. The bolt holder 19 is a bolt holder of any type, suitable for carrying a bolt shown diagrammatically at 20 of any type comprising a hook 21 extending in the locking direction 18 over a distance substantially equal to the distance A separating the two unlocked and locked positions of the outer plate (see figures 3 and 4).

As shown in detail in Figures 5, 6 and 9, the means for guiding the outer plate 3 include, for each fastener 14, 15, two let us hold 22, 23 respectively protruding in the transverse direction 24 of light 8 in one direction opposite, formed on the fixing member 14, 15 corresponding and grooves 25, 26 extending in the longitudinal direction 11, adapted to receive each a respective tenon 22, 23 and formed under the plate 3.

We could alternatively provide the studs on the plate and the grooves on each fixing member.

We see in Figures 3 and 4 that the width of the fasteners 14, 15 between the pins 22, 23 is less than the width of the light 8 so that allow insertion between the fixing member 14, 15 and the longitudinal edges 4, 5 of the light 8, two longitudinal edges 27, 28 integral with the plate 3 and respectively carrying grooves 25, 26.

In the example shown in the figures and in particular in FIGS. 5 and 6, each fixing member 14, 15 includes a main U-shaped element 31 forming a jaw and comprising an outer wing 32 and an inner wing 33 extending, when said member 14, 15 is engaged with the wall 9, in the direction longitudinal 11 of light 8 on the same side of a transverse core 34, and adapted to be placed one 32 outside, the other 33 inside the wall 9 of opening it 2.

It can be seen, in particular in FIGS. 1, 8 and 9, that the height H between the wings 32 and 33 is greater than the thickness E of the wall 9 (See FIG. 9).

We also see in these figures that a blade of spring 35 is fixed on the face of a wing 32, 33 in look of the wall 9, in the present example the face 33a of the inner wing 33. This blade 35 is inclined relative to this wall 9 so as to allow the insertion of the wings 32, 33 of the fixing member 14, 15 correspondent on either side of the transverse edge 6, 7 corresponding to the wall 9, and to oppose a movement in the opposite direction of said member 14, 15.

The blade 35 is for example made of steel stainless when the wall 9 is made of aluminum or light alloy so that you can hang in the metal of the wall 9 once the fixing member correspondent is in place on both sides of the edge transverse 6, 7 respectively: thus, the blade 35 is capable of opposing a displacement of said member 14, 15 in the opposite direction to the insertion direction, that is to say to a displacement in the direction in which this blade 35 is inclined relative to the wall 9.

The outer plate 3 has two lights 36, 37 extending longitudinally and adapted to slidingly receive the outer wing 32 of the corresponding fixing member 14, 15.

It can thus be seen that the length in the longitudinal direction 11 of the openings 36, 37 is equal to the sum of the length L in the longitudinal direction of the outer wing 32 and the length A of the sliding movement of the outer plate 3 relative to to wall 9 (see Figure 3).

At least one, 15, of the fixing members 14, 15 includes means for blocking the outer plate 3 in its locked position, and means for unlock said outer plate 3 to move it away from this locked position.

In the present example, the second organ of fixing 15 opposite to the locking direction 18 comprises a connected member 38 extending longitudinally by report to organ 15 and connected to said organ 15 and bearing means for blocking the outer plate 3 relative to the wall 9.

The connected member 38 extends in the locking direction 18 relative to the member 15 and comprises two elements forming stops 41, 42 separated from each other in the longitudinal direction 11 by a distance equal to the displacement A sliding of the outer plate 3 relative to the wall 9, and adapted to abut against the edge 47 constituting the first edge, in the locking direction 18, of the light 37, respectively one 41 in the locked position of the outer plate 3, shown in FIGS. 1 and 3, the connected member 38 being in a first position, shown in these figures, the other 42 in the unlocked position of the outer plate 3, shown in FIGS. 4 and 8, after pivoting of said connected member 38 in the direction of arrow 43 in FIGS. 1 and 8 towards a second pivoted position of said connected member 38 shown in FIG. 8.

The related organ 38 is connected to the second organ fixing 15 by a spring blade 39 making hinge function along an axis, shown schematically at 40 to Figure 4, extending in the transverse direction 24 of light 8, this blade 39 extending parallel to the wings 32, 33 of said second member of fixing 15.

In the locked position of the plate exterior 3, the related member 38 is in its first raised position, in which the element 41 is in taken with edge 47 (see Figures 1 and 3).

In the unlocked position of plate 7, the member 38 is in its second pivoted position, in which element 42 is engaged with edge 47 (see figures 4 and 8).

We see in the figures that the connected member 38 has the form of a plate extending parallel to the wall 9 when the second fixing member 15 is in position on said wall 9. The outer face 44 of the member related 38 is hollowed out in steps on the side opposite the hinge 39 to form two edges 41, 42 adapted to engage with song 47 of the second light 37. The first edge 41 corresponds to the free edge of the related organ 38 and is engaged with the song 47 in the locked locked position of the plate exterior 3 shown in Figures 1 and 3. The second edge 42 corresponds to the step of face 44 and is in taken with edge 47 in the unlocked position of the outer plate 3, shown in FIGS. 4 and 8, after pivoting of the connected member 38 in the direction 43 towards the inside of the opening 2 under the action of a pressure in this direction 43 exerted on the outer face 44 of said member 38 and shown diagrammatically by arrow 43 at the figure 1.

To facilitate the release operation, the related member 38 has a width in the direction transverse 24 equal to the width of the light 8, which is the maximum possible width.

Likewise, a concave footprint 51 to facilitate finger application is spared on part 52 of the outer face 44 between the hinge 39 and the song 42.

Therefore, the light 37 comprises at its end in the direction of locking 18 part widened 53 for the passage of the related organ 38 and which is limited in the locking direction by the edge 47.

Spring means 48 are provided between the outer plate 3 and one 14 of the attachment 14, 15 so as to permanently stress the plate 3 in the opposite direction to the locking direction 18.

So, as soon as we unlocked song 41 by compared to song 47 by pressing in the direction of arrow 45 on the imprint 51 of the related member 38, the spring 48 causes the plate to move outside 3 in the unlocking direction thereof. It is easy to size the spring 48 so that this movement goes to the unlocked position of the outer plate 3 shown in Figures 4 and 8.

As shown in Figure 5, we have advantageously provided a hole 49 in the face transverse 50 of the first fixing member 14 for serve as a base for spring 48 (See Figure 5). A hole equivalent not shown is advantageously spared in the face opposite the sliding assembly 10.

For the insertion and installation of the sliding assembly 10 comprising the outer plate 3 and the fixing members 14, 15, in the slot 8, we see that the fasteners 14, 15 can swivel slightly around the edge of the blade 35 in engagement with the wall 9, which facilitates the insertion of the pins 22, 23 in the grooves 25, 26.

We start with organ 14: we introduce the upper wing 32 in the light 36, then we insert the organ 14 straddling the edge 6 of the light 8. We places the outer plate 3 in its position locked.

The member 15 is then introduced into the part widened 53 of light 37, we place the plate outside 3 on the wall 9 and insert the member 15 to horse on edge 7, the connected member 38 being raised outwardly relative to member 15 so as not to hinder the maneuver described above.

As a variant, the organs of attachment 14, 15 on the sliding assembly 10, then just fix said sliding assembly 10 by snap on edges of light 8.

To facilitate this insertion operation, the tenons 22, 23 advantageously have one of their faces parallel to the wings 32, 33 inclined to form a slope or ramp (not shown) facilitating insertion tenons 22, 23 in the grooves 25, 26.

We have thus described a fitting structure particularly simple, suitable for a very economical in plastic. In particular, the insertion of blades 35 and 39 is very easy for a plastic material.

In this structure, the classic shell consisting of a housing and a cleanliness plate of a in one piece with the housing, is reduced to the plate cleanliness alone which also fulfills the function of conventional slide consisting of an operating member monobloc and a bolt holder.

This structure allows a simple installation and fast in light 8, this positioning being specifies despite the simplicity of the means used.

Of course, the present invention is not limited to the embodiment which we have just describe, and we can bring to this many changes and modifications without departing from the scope of the invention.

You can easily use light 36 or 37 as a means of signaling the position of the plate exterior 3, to show colored areas on either side of wing 32 of organ 14.

The related organ 38 is connected to the second organ fixing 15 by an element 39 forming a hinge.
