A movable part (13) slides relative to a casing forming a runner (12) in the transverse direction and is fixed to the sensor and to the stop.

Description

The present invention relates to a fitting of lock for sliding door, window or the like, comprising a bolt secured to an assembly sliding movable relative to a profile making integral part of said fitting, this fitting comprising an anti-tampering device.

We know, from FR-A-2 700 578 a fitting of the aforementioned type comprising an anti-false device operation comprising a movable feeler finger substantially in the transverse direction of the profile and permanently stressed by elastic means towards its extended position, and an element forming a stop integral with the probe and adapted to cooperate with complementary means of the sliding assembly so such that said stop member prevents, in the position extended from the probe, sliding the bolt towards its locked position, without opposing it sliding in the retracted position of the probe.

According to this document, the feeler finger is mounted on a rod, for example a leaf spring. As long as the probe, encountering no obstacle, remains in its extended position, the end of the rod blocks a slide carrying a bolt and preventing the sliding of the bolts to its locked position.

On the contrary, when the probe comes into contact with a strike, this strike repels the probe and the rod which frees the slide to allow sliding the bolt to its locked position.

This embodiment is fragile and is not reliable.

We know, from GB 2 177 452, a fitting of lock for sliding door, window or the like, comprising a profile, a set sliding movable relative to the profile, a bolt integral with the sliding assembly and a device anti-false operation which includes a feeler finger movable and permanently stressed towards its position exit by elastic means, an element forming stop secured to the feeler finger and adapted to cooperate with means complementary to the sliding element in such a way that the stop element prevents, in the extended position of the feeler finger, a sliding of the bolts to its locked position, without opposing it sliding in the retracted position of the feeler finger, and a movable member secured, on the one hand, to the finger feeler and, on the other hand, the stop member.

However, this achievement is not satisfactory especially in its mounting and installation.

The object of the present invention is to remedy to the disadvantages of known fittings, and to propose a fitting of the aforementioned type which is simple, economical, extremely reliable, and easy to assemble and install.

According to the present invention, the fitting of the aforementioned type is characterized in that it is suitable to be introduced through a light provided on a wall on the inside of the sliding sash and be fixed on the edges of the light, and in that it includes a slide housing that extends substantially in the transverse direction of the profile, which includes means adapted to cooperate with additional means integral with the profile for fixing the housing with the profile, and inside which the organ of the anti-tamper device is mounted sliding way in the transverse direction of the profiled against the action of elastic means also housed inside the housing.

Thus, the stop member and the finger probe are integral with the movable member which is mounted slidingly relative to the housing forming slide, which is fixed to the profile. The feeler finger is thus guided precisely to be able to ensure reliably the function of anti-fake device maneuver.

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

In the embodiment shown in Figures, the locking fitting 1 for opening: sliding door 2, window or the like, has a bolt 3 secured to a sliding assembly, shown schematically in 4, movable relative to a profile 5 forming part integral of fitting 1 which is housed inside of the opening.

This fitting 1 comprises an anti-false device 6 operation comprising a movable feeler finger 7 substantially in the transverse direction 8 of the profile 5 and permanently stressed by elastic means 9 towards its extended position, in the direction shown schematically by the arrow 10 in Figure 2.

The anti-false operation device 6 comprises also .a stop element 11 integral with the probe 7 and adapted to cooperate with means complementary to the sliding assembly 4 so such that said stop member 11 prevents, in the extended position of the probe 7, shown in the figure 2, a sliding of the bolt 3 towards its position locked, without opposing this sliding in the retracted position of the probe 7 shown in the figure 11.

As shown in Figure 2, the bolt 3 has two opposite hooks 3a, 3b, so as to be reversible and able to be arranged in one direction and on any side on the bolt holder 59 mounted on the sliding assembly 4 which is itself of a type any.

The hook 3a is adapted to slide in the sense 60 to engage, in its position locked in figure 11, with the hook additional 61 of the strike 62.

This sliding is authorized as soon as the opening 2 carrying the bolt 3 has been moved in the direction 10 towards the frame (not shown) carrying strike plate 62 until the probe 7 comes into contact with the bearing 63 secured to keeper 62 and be pushed back by this range 63, in the opposite direction to sense 10 relative to the profile 5, to its retracted position shown in the figure 11.

According to the invention, the fitting 1 comprises a housing forming slide 12 adapted to be fixed by relative to profile 5 and extending substantially in the transverse direction 8 of the section 5, and a member mobile 13 slidably mounted relative to said housing forming slide 12 in said direction transverse 8, and integral, on the one hand, with said probe 7, on the other hand, of said stop element 11.

In the example shown, the housing 12 includes means adapted to cooperate with means complementary to the profile 5 to fix the housing 12 profiled audit 5.

These means are here latching means.

The fitting 1 comprises a support 14 fixed to the profile 5 and comprising a housing 15 adapted to receive the case 12.

In this example, the support 14 of the housing 15 is integral with the body 16 of a fixing member 17 suitable for engaging, on the one hand, with the profile 5, on the other hand, with a transverse edge 18 of a light 19 formed on a wall 20 on the inner side of sliding leaf 2, for fixing by snap-on of profile 5 on the edges of said light 19, and is in particular integral with a part median 21 of body 16 protruding between the two longitudinal edges 22, 23 of profile 5 (see figure 12).

As shown in particular in Figures 2, 3, 7 and 12, the support 14 is fixed on the middle part 21, or is an integral part of the middle part 21, of the body 16.

The support 14 includes two transverse walls 14a, 14b defining between them the housing 15, the bottom is formed by the surface 21a of the middle part 21.

To delimit the housing 15 opposite the bottom 21a, the support 14 also includes two flanges 14c, 14d, extending respectively towards each other in the direction 24 from the transverse walls 14a, 14b and delimiting between them a transverse light 14e in which the stop element can slide 11.

The flanges 14c and 14d only extend over a middle part of the transverse walls 14a, 14b of the support 14.

Furthermore, we see in Figure 1 that the latch holder 59 protrudes between the two edges longitudinal 22, 23 of profile 5 relative to the sliding assembly 4, and extends, like the support 14, between the wall 20, on the inside, and the wall 64, on the outside, of the opening 2.

The bolt holder 59 has, facing and at level of flanges 14c, 14d, two arms 65, 66 extending in the longitudinal direction 24 of the profile 5 substantially in line with the edges longitudinal 67, 68 of the bolt holder 59, on both sides on the other side of the flanges 14c, 14d.

We see in Figure 2 that the free end 65a arm 65 is spaced from the stop member 11 by a space whose function we will see below.

We also see in this figure that the organ forming stop 11 is in the extended position of the finger probe 7, placed on the path of the free end 65a of the arm 65 and opposes a movement of the bolt holder 59 and bolt 3 in the direction 60 towards the position locked from the latter.

This avoids any risk of damaging the bolt 3 by impact against strike 62 during closing inadvertent opening 2 while the bolt would in its locked position.

On the contrary, when the feeler finger 7 is in its retracted position shown in FIG. 11, the stop member 11 is located between the flanges 14c, 14d and can no longer oppose the passage of the arm 65 and when the bolt holder 59 and bolt 3 slide in the direction 60 towards the locked position of the latter.

In this example, and as shown in detail in Figures 1 and 3, the fixing member 17 is a fastener movable in the direction longitudinal 24 of profile 5.

The fixing member 17 thus comprises a ramp 25 extending substantially from the transverse edge 18 of light 19 towards the inside of the opening 2 and towards the center of the light 19. Near the wall 20 of opening 2, the ramp 25 forms a projecting dihedral 26 which continues with a second ramp 27 ending in a returning shoulder 28.

When the profile 5 is pressed against the edges of the light 19, to introduce it by the light 19 inside the opening 2, the ramp 25 is supported on the transverse edge 18 of the light 19 and force the fixing member 17 to slide in the direction longitudinal 24 in the direction 24a towards the inside of the light 19 against the action of a spring not shown.

When the protruding dihedral 26 reaches the level from the edge 18 of the light 19, a last push on the profile 5 drives said protruding dihedral 26 towards inside the door. The aforementioned spring pushes back then the fastener 17 in the other direction so that the returning shoulder 28 and the second ramp 27 engage the edge 18 of the light 19 for snap the profile 5 and the cleanliness plate 5a onto the wall 20 of the opening 2.

In this sliding movement, the attachment 17 is guided by the longitudinal edges 22, 23 of profile 5, and is retained at the end of profile 5 by a puncture 29 formed on the side walls 30, 31 profile 5 and constituting a protruding tongue inward of profile 5 and received in a groove 32 corresponding extending in the direction longitudinal 24 and formed on the two lateral faces of organ 17.

This sliding movement of the organ of fixing 17 to allow the snap of the fitting 1 on the wall 20 of the opening 2 is made possible by the free space, shown in Figure 2, between the free end 65a of the arm 65 of the bolt holder 59, in the open position of the bolt 3, and the stop member 11 in the extended position of the feeler finger 7.

The fitting 1 and the anti-false device 6 maneuver are shaped so that the finger probe 7 can be mounted on either side or the other of profile 5.

The movable member 13 is movable along a cavity 33 extending in the transverse direction 8 of the profile inside the housing 12 (see Figures 4A, 4B and 8. The feeler finger 7 passes through a hole 34 formed in a first end wall 35 of the housing 12 substantially perpendicular to the transverse direction 8. The stop element 11 is connected to the member movable 13 by a connecting portion 36 which passes through a light 37 formed in a side wall 38 of the housing 12 and extending in the transverse direction 8, and slides along this light 37 in said transverse direction 8.

As shown more precisely in the Figure 8, the cavity 33 and the light 37 open at level of the second end wall 39 of the housing 12 in an opening 40 shaped so as to allow the introduction of the movable member 13, carrying the element forming stop 11, inside the housing 12. We see, in particular in FIGS. 2, 8 and 11, that the cavity 33 has, before the second end wall 39, a peripheral flare 41, arranged in such a way that the inner surface 42 of the second end wall 39 serves as a seat for an enlarged end turn 43 of a coil spring 9 introduced into the cavity 33 between the movable member 13 and the second end wall 39.

For fixing the housing 12 in the housing 15 of the support 14, the housing 12 comprises, in the vicinity from its first end wall 35, means forming stop 44 adapted to come into engagement with the support 14, and, in the vicinity of its second end wall 39, elastic means 45 adapted to snap into place with corresponding support means 14.

For this purpose, the housing 12 comprises in the vicinity from its second end wall 39 at least one wing flexible 46 comprising a lug 47 projecting towards the outside of the case, and the wing 46 is sufficiently flexible to allow the housing 12 to be threaded, by its second end wall 39, inside the housing: 15, the lug 47 coming to snap on the edge outside of the housing 15 as soon as it comes out of it.

In the example shown, the flare peripheral 41 household two flexible wings 46 bearing to their end a respective part of the second wall end 39, each wing 46 carrying a lug 47.

As shown in detail in Figures 4, 5, 7, 8 and 11, the housing 15 has at each end in said transverse direction 8 two recesses 48 diametrically opposite, and the housing 12 presents at right of its first end wall 35 two ears 49 diametrically opposed, and to the right of its second end wall 39 two pins 47 diametrically opposite, each carried by a wing 46, the ears 49 and the pins 47 being adapted to be received in the recesses 48 from either end of the housing 15.

To allow on-site adjustment of the position of probe finger 7, the latter is advantageously mounted at the end of a rod 7a externally threaded which is screwed into a corresponding threaded bore 13a of the movable member 13.

The structure described above of the case forming slide 12 lends itself very well to a realization of this case in a very material economical easy to work and shape, for example in a plastic material such as polyamide. It is the same for the movable member 13.

Of course, the present invention is not limited to the embodiments which we have just describe, and there are many changes and modifications without departing from the scope of the invention.

We can thus renounce the symmetrical character, with respect to a longitudinal plane of symmetry of the profile 5, of the fixing member 17, of the support 14 and of the bolt holder 59, which allows the housing 12 to be mounted and: the feeler finger 7, like the bolt 3, on one side or the other of profile 5.

One can also provide a support 14 fixed in any way to profile 5.

We can also provide an identical dimension, in the transverse direction 8, of the support 14 and of the case 12 whatever the width of the profile 5 according to this direction 8.
