Description

Locking hardware for sliding leaf.

The invention relates to a locking hardware for sliding leaf that includes a fixing plate that has an access opening to a slider mounted axially movable in a box that extends perpendicularly behind the plate fixation.

The present invention relates, in particular, to the scope of the lock fittings for sliding leaf.

Numerous lock fittings are already known that correspond to the description above. So, such hardware they have a planned box capable of registering in the thickness of the front upright of a sliding blade, behind a plate fixation.

Anyway, the box is constituted, substantially, by said fixing plate and two walls parallel that extend perpendicularly behind this plate, knowing that these walls are provided substantially to the height of its free end edge, of an elbow that delimits, thus, with the internal fixing plate, a guide channel of a slide. In summary, the latter is part of the above mentioned elbows and the rear face of said internal fixing plate. Such design is described for example in the document EP-0859107.

The internal fixing plate also includes a longitudinal opening that allows direct access to the slide that is then provided with a bucket handle. This slider acts on a slide holder in which it is inserted, of Adjustable mode, lock latch.

In particular, during the assembly of the hardware, the slide is mounted in the box from one or the other end of the latter.

This type of blade lock hardware Sliding raises a problem of mechanical resistance of the box in "U" profile shape.

It will also be noted that the document is known FR-2,761,791, a blade lock hardware slide that includes a box, here also defined by two parallel walls that extend perpendicularly behind a fixing plate and between which it moves longitudinally a slide. The latter is planned capable of being activated by means of a maneuvering body accessible through an opening provided in said fixing plate. Act on a toothpick holder planned capable of receiving a locking latch that, under the action of said slide, is likely to be taken to cooperate with a strike after closing the sliding leaf.

This locking hardware also has two hooking organs intended to be placed at the ends of the box after having inserted in the latter the above mentioned slide. In fact, the box is, here too, constituted by side walls that extend perpendicularly behind the fixing plate

These hooking organs are adapted to cooperate with the singing of the light usually provided at the level of the sliding blade for receiving said locking hardware. To the less one of these hooking organs is provided elastically retractable To the extent that these hooking organs are defined so that they act in longitudinal directions opposite, that allows, for example, the hooking of one of these organs in the singing of said light, at one end Longitudinal of the latter. While, regarding the extreme opposite of this light, the other hooking organ is capable of elastically retract to, after the corresponding step board this light, engage, by elastic recoil, with the song of the latter.

So, this organ hooked elastically retractable features a tight section for sliding installation at one end in the box, enter, on the one hand, the parallel walls and, on the other hand, the fixing plate and the elbows they equip, in its free end, said parallel walls.

In these longitudinal parallel walls, this hooking body in particular involves longitudinal grooves  in which they are pushed, after insertion at the end of the box, knives made at the level of the parallel walls of the latter.

As for the elastic elbow, this is secured by a spring that is inserted, in part, in a recess planned to level of the rear face of this hooking organ. It is supported, also, against a stop tab that extends transversely in the box. This tab is defined by example, by trimming on one of the side walls.

Finally, the box is weakened due to necessary openings, on the back face and / or at its ends, to the mobile assembly of the slide and can only have a rigidity relative.

It is within the framework of a first inventive stage that has been designed to mount the slide in the hardware box, from the longitudinal opening that the fixing plate entails normally and that usually serves exclusively for Secure your maneuver.

Thus, the invention relates to a hardware of sliding leaf lock that includes a fixing plate that it has an access opening to a mobile mounted slide axially in a box that extends perpendicularly behind the fixing plate, terminated because the slide is provided flexible in the longitudinal direction, to ensure its insertion, by bending, in the box through the longitudinal opening in the fixing plate.

According to another particularity of a way of embodiment of the invention, the slide includes integrated means  of reception of a portapestillo.

According to an advantageous embodiment of the invention, the box is designed to authorize relative mobility  of the slide and allow it, on the one hand, to reach, from a unlock position, a lock position, and vice versa, and, on the other hand, occupy a position of assembly-disassembly, in which one of the ends of said slide is susceptible to be removed or, during assembly, to be inserted in said box through the opening in said fixing plate, while the other end of said Slider is inserted in said box.

In this case, the box can, advantageously, be constituted in monobloc mode and have two side walls parallel, extreme walls and a bottom, closing the latter in the rear, knowing that in the front this last it entails, in a solidary way, a cover defined by the fixation.

In addition, according to an advantageous embodiment of the invention, at least one of the parallel side walls of the box has an opening for the passage of the stem of a lock latch, so as to allow the cooperation of the latter with said slide holder associated with the slide mounted in the box.

In particular, the opening in said wall lateral parallel in the box is defined of a length that allows to the locking latch a path, between a locking position and an unlocked position, under the impulse of the slide.

In short, this light on the side wall parallel of the box pierced by the rod of the latch blocking, limits, in cooperation with the latter, the route of the slide that, at the beginning, has a more important route to be inserted in the box.

According to another particularity of a way of embodiment of the invention, the box implies, in each of its longitudinal ends, a defined engagement device capable of act in opposite longitudinal directions and designed to cooperate with the singing of a light provided on a sliding sheet to receiving said locking hardware, at least one of these hooking organs is defined elastically retractable.

More particularly, at one of its ends said locking hardware box is extended by a box of reception of the elastically retractable hitching organ.

According to another particularity of a way of embodiment of the invention, the wall that defines the bottom of the box  it involves at least one recess internally to said box that allows, in particular, make this last rigid.

The object of the present invention will be better understood to read the description that follows, with reference to the attached drawings, in which:

Figure 1 is a schematic representation and in perspective of the locking hardware according to an embodiment  of the invention;

Figure 2 is a broken down view and in perspective of this locking hardware for sliding leaf;

Figure 3 is a schematic representation in lifting the lock hardware box;

Figure 4 is a schematic representation in plane of this locking hardware;

Figure 5 is an elevation representation of this locking hardware;

Figure 6 is a detail and sectional view. according to VI-VI of figure 4.

As it is represented in the figures of the attached drawings, the present invention relates to a hardware 1 lock for sliding leaf.

It includes a fixing plate 2 that has a longitudinal opening 3 for access to a slide 4 mounted axially movable in a box 5 that extends perpendicularly behind the fixing plate 2.

The slide 4 acts on a slide holder 6 which can receive a lock latch 7, represented schematically in figure 4.

According to the invention, the slide 4 is designed flexible in the longitudinal direction to ensure, by flexion, its insertion in box 5 through the opening longitudinal 3 of the fixing plate 2. Thus, this slide 4 It can be made of plastic material. The present invention without However, it is not limited to such an embodiment of this slide 4.

Advantageously, the box 5 is constituted so monobloc and has two parallel side walls 8, 9 joined together, at the back, for a bottom 10.

This box 5 is also closed on both sides by extreme walls 11, 12, knowing that in the front It has a cover defined by the fixing plate 2.

According to a particularity of a way of embodiment of the invention, the longitudinal opening 3 in the plate of fixing 2 is shorter than that of the slide Four.

Thus, according to a first embodiment, the slide 4 is folded, by flexion, for insertion into the box 5, passing through this opening 3.

According to another embodiment, the path of this slide 4 in box 5 is defined so that not only can move from a locked position to an unlocked position e inversely, but also so that, in an additional displacement to reach an assembly-disassembly position, one 13 of the ends of the slide 4 is capable of being removed or of inserting into said longitudinal opening 3, while the other  end 14 of this slide 4 remains inserted in the box 5 through this opening 3.

It is well understood that, in such a way of embodiment, this insertion is carried out by an operation of transfer of slide 4 in box 5.

Obviously, this additional tour of the Slider 4 in box 5 can be determined or limited, in Flexibility function of the latter. In other words, to through this flexibility of the slide 4 this tour additional may be smaller compared to a slide that It would be rigid.

On the other hand, it will be noted that this flexibility of the slide 4 allows to contemplate an assembly without excessive play of the latter in box 5.

Very particularly, said slide 4 is defined by two end parts 15, 16 joined by a sheet flexible central 17.

Advantageously, one of the end parts 15 defines a reception box 18 of the slide holder 6 of which provides the slide 4 before mounting in box 5. In summary, the 6 holder is intended for insertion in this box of reception 18, before the insertion of the slide 4 in the box 5. It is obvious that assembly operations are thus facilitated. In effect, after having positioned the slide 6 in this box 18 of the slide 4, enough, within the framework of a last operation, insert the latter into its housing defined by the box 5 of the hardware, to finish the assembly of the latter.

For this purpose, at least one of the walls lateral parallels 8, 9 of the latter behaves, in front of said pin holder 6, an opening 19 to allow the stem 20 of the Lock latch 7 cooperate with the slide holder 6.

According to an advantageous embodiment of the invention, this opening 19 is defined to allow the rod 20, therefore to lock latch 7, a path that corresponds to its passage from the locked position to the position of unlock, and vice versa.

In short, through your cooperation with the rod 20 of the locking latch 7, this opening 19 limits the sliding travel of the slide 4, whose travel is possibly more important to allow assembly, as It has been explained above.

According to another feature of the invention, the end portion 15 of the slide 4, which constitutes a box of reception 18 of the slide holder 6, includes an access opening 27 to a tightening screw 29 for locking the rod 20 of the locking latch on said slide holder 6. In particular, this opening 28 at the end portion 15 of the slide 4 is defined to be accessible when the latter is pushed in a position, for example unlock, as visible in the figure Four.

In particular, the bottom 10 of the box 5 it comprises at least one recess 21 internally to said box 5 which it allows, in particular, to make the latter rigid.

According to another particularity of a form of embodiment of the invention, the slide 4 comprises means of Indexing of your locked and unlocked position, provided able to cooperate with complementary indexing means that the box 5 receive.

In particular, at its end 14, opposite to the extreme part 15 that comprises the slide holder 16, said slide 4 may be extended by one or more elastic sheets 22 provided with at least one indexing bushing 23 capable of cooperating with breaks 24 that constitute the means of indexing complementary that involves the bottom 10 of box 5. Here also, thanks to the flexible character of the slide 4, these elastic sheets 22 can be obtained by molding plastic material of said slide 4.

As visible in the figures of the drawings attached, breaks 24 are provided at recess level 21 that this bottom 10 involves, at one end 25 of this box 5.

For this purpose, the extreme wall 12 that is last behaves at this end 25 advantageously presents one or several openings 26 that can pass through the elastic sheet (s) 22, for example to confer to the slide 4 this mobility relative relative to box 5, to allow mounting.

It will also be noted that recoil means elastics 27 can act between this end wall 12 and the corresponding end 14 of the slide 4, to ensure a automatic retraction of the latter, for example in the position of blocking.

According to an embodiment of the invention also, the locking hardware 1 involves two hooking organs 30, 31 defined capable of acting in longitudinal directions opposed and planned to cooperate with the singing of light, in a sliding sheet, against which it is intended to be applied said locking hardware 1.

In particular, beyond one of the walls of end 11, the box 5 is extended by a box 32 receiving an elastically retractable engagement member 31 defined.

Thus, in this reception box 32, this organ of hooked 31 is mounted sliding against the action of means elastic recoil 33, which allows it to retract with respect to the corresponding edge of light on the sliding sheet when said Lock hardware fits into it.
