Description

DESCRIPTION

Peripheral set for multipoint locks

The present invention refers to a peripheral assembly for multipoint locks and, in particular, the invention refers to one of the assemblies by means of which the lock can ensure the locking of the doors and windows in which it is installed, in areas far from the lock itself (by adapted transmission elements interposed between the lock and the assembly itself).

Multipoint locks are made up of a substantially traditional mechanism (a standard lock), provided with transmission elements (generally arranged above and/or below it) that are associated, including the interposition of adapted elements designed to also transmit mechanical commands, with specific peripheral assemblies provided with a respective sliding latch that is adapted to removably engage in a housing cavity facing it when the lock is in the closed configuration.

Said peripheral assemblies are known in the sector as latches, and they ensure a considerable increase in the resistance against manipulation of the door leaf that is equipped with them. Document EP 1234938 A2 discloses an example of a peripheral assembly for multipoint locks.

The peripheral assemblies can be provided with sliding prism-shaped latches that translate (which carry out a movement of translation back and forth with respect to the box-shaped body that contains them to engage in a respective seat of the jamb) and hook-shaped slide latches that rotate (rotate on a fixed axis and go from a retracted to an extracted configuration where they engage the jamb seat).

The second type described is particularly safe, because it prevents intrusion maneuvers to force the door leaf thanks to the retention generated by the hook-shaped structure.

Breaking and flattening procedures are known, which are carried out against sliding latches in the form of a hook, which consist of applying a force directly to the hook so that it rotates in the opposite direction until it is fully retracted.

The purpose of the present invention is to solve the aforementioned disadvantages, providing a peripheral assembly for multipoint locks that prevents intrusion actions intended to force the hook-shaped sliding latch to rotate in the opposite direction for the corresponding retraction.

Within this purpose, an objective of the invention is to provide a peripheral assembly for multipoint locks that guarantees maximum security against intrusion actions to force the door leaf.

Another objective of the invention is to provide a peripheral assembly for multipoint locks that is made up of a reduced number of simple and easy-to-assemble components.

Yet another objective of the present invention is to provide a peripheral assembly for multipoint locks that is low cost, simple and practical to carry out and safe to use.

This purpose, and these and other objectives that will be made clear below, are achieved by means of a peripheral assembly for multi-point locks of the type comprising a box-shaped body to house at least one actuating rod of at least one latch slider that is pivoted on an inner wall of said box-shaped body and that can move between an extracted configuration and a retracted configuration, with respect to said box-shaped body as a result of the corresponding translations of said stem along of a path inside said box-shaped body that is defined by at least one first slot thereof, inside which at least one first stud is coupled that forms a single piece with an inner wall of said box-shaped body , characterized by:

- said actuation rod comprises at least one second contoured groove for the sliding housing of the pin to pivot said at least one sliding latch, said pin being provided with an eccentric projection that can be housed, in the configuration of total extraction of said sliding latch, in a respective recess of said second slot,

- at least one rocker arm, which is pivoted on said block that forms a single piece with said inner wall of said box-shaped body, comprises an end tab that is contoured and adapted to abut a gap in the edge of said sliding latch, of shape and dimensions substantially complementary to those of said tongue, insertion of said tongue into said recess blocking rotation of said sliding latch,

- a projection of said stem, facing and protruding towards said inner wall of said box-shaped body to which said stud is coupled, aligns with a part of said at least one rocker arm, causing said stem to translate bearing of said projection on said part of said rocker arm, forcing the rotation of said rocker arm, with respect to the stud, the distance of said hollow from said sliding latch.

Other features and advantages of the invention will be better appreciated from the following detailed description of a preferred, but not exclusive, embodiment of the peripheral assembly for multipoint locks according to the invention, which is illustrated by way of non-limiting example in the drawings attachments, in which:

Figure 5 is a partially cross-sectional side view of the peripheral assembly of Figure 1 in a fifth configuration;

Figure 6 is a partially cross-sectional side view of the peripheral assembly of Figure 1 in a sixth configuration.

With reference to the figures, the reference number 1 generally designates a peripheral assembly for multi-point locks.

The peripheral assembly 1 for multi-point locks comprises a box-shaped body 2 to house at least one actuating rod 3 of at least one sliding latch 4 that pivots on an inner wall of the box-shaped body 2.

Slide latch 4 is positively movable between a withdrawn configuration (exemplary shown in Figure 1) and a retracted configuration (exemplary shown in Figure 4) with respect to the box body 2 as a result of corresponding translations of the actuating rod 3 along a path within the box-shaped body 2, which is defined by at least a first slot 5 thereof into which at least a first plug 6 that forms a single piece with an inner wall of the box-shaped body 2.

The actuating rod 3 comprises at least one second groove 7 contoured for the sliding housing of the pin 8 for pivoting said at least one sliding latch 4.

The pivot pin 8 is provided with an eccentric projection 9 which can be housed, in the fully withdrawn configuration of the slide bolt 4, in a respective recess 10 of the second slot 7.

At least one rocker arm 11, which is pivoted on the stud 6 which is integral with the inner wall of the box-shaped body 2, comprises an end tab 12 which is contoured and is adapted to rest in a hollow 13 from the edge of the slide latch 4.

The hole 13 has a shape and dimensions substantially complementary to those of the tongue 12: the insertion of the tongue 12 in the hole 13 blocks the rotation of the sliding latch 4 (and, therefore, constitutes a particularly effective and relevant anti-intrusion device). ).

A projection 14 provided on the drive rod 3 faces and protrudes towards the inner wall of the box-shaped body to which the stud 6 engages.

The projection 14 is aligned with a part of said at least one rocker arm 11: a translation of the rod 3 causes the projection 14 to rest on a part of said rocker arm 11, forcing it to rotate with respect to the stud 6 to which it is attached, moving away from the recess 13 of the sliding latch 4.

With particular reference to an embodiment of undoubted application interest, the eccentric projection 9 of the pin 8 is substantially wedge-shaped.

The recess 10 of the second slot 7 has a complementary shape and a greater width with respect to the projection 9, for its accommodation with clearance.

The clearance present between the projection 9 and the recess 10 is necessary to ensure that, during the turns of the sliding latch 4 (corresponding to the transition from the extracted configuration to the retracted configuration thereof), the projection 9 can change its orientation (following that of the sliding latch 4 with which it forms a single piece) without impacting the walls of the slot 7 that delimits it (particularly that of the recess 10).

Advantageously, the assembly 1 may comprise a spring latch 15 which is held in a configuration at least partially protruding from the box-shaped body 2 by respective elastic means (not shown in the attached figures).

At least one actuating lever 16 is pivoted on the stud 6 which forms a single piece with the inner wall of the box-shaped body 2.

A translation of the stem 3 (by way of example, with reference to the embodiment shown in the attached figures, a translation of the stem 3 towards the upper part of the box-shaped body 2) can suitably cause the support of the respective projection 14 on a margin of the lever 16, with the consequent retraction of the spring latch 15 in the box-shaped body.

The spring latch 15 may positively comprise an actuating rod 17 disposed within the box-shaped body 2.

In this case, the actuating rod 17 will be provided with a shoulder 18: the end 19 of the actuating lever 16 will rest on the shoulder 18 in a translational manner of the actuating rod 3 and of the projection 14 forming a single piece with the same, will force the projection 14 in a margin of the lever 16, with the consequent rotation of this with respect to the block 6. Said rotation will entail the displacement of the end 19 of the lever 16, with the consequent dragging of the shoulder 18 of the stem 17 and , therefore, of the spring latch 15.

It should also be noted that the stem 3 comprises a third slot 20, parallel to the first slot 5, which is designed to slidably house a second stud 21 that forms a single piece with an inner wall of the box-shaped body 2.

The first slot 5 and the third slot 20, in coordination with the first stud 6 and the second stud 21, define the travel and translation path of the stem 3 in the box-shaped body 2.

It should also be noted that, interposed between the rocker arm 11 and the block 6, which forms a single piece with the inner wall of the box-shaped body 2, an (angular action) spring is advantageously provided for the forced rotation of the rocker arm. rocker arm 11 in the bearing configuration of its contoured end tab 12 in the recess 13 of the sliding latch 4.

In this way, the force exerted by the spring ensures that the safest condition is maintained against any manipulation attempt, since it keeps the tongue 2 in contact with the hole 13 and, therefore, blocks the turns of the sliding latch 4.

It should be noted that, according to a particularly functional embodiment, the sliding latch 4 can advantageously have a substantially C-shape: in an initial part 22 there is the hole for housing the pivot pin 8 of the wall of the box-shaped body 2 and, at the outer edge of an intermediate part 23 thereof is the recess 13, while an end part 24 protrudes completely from the box-shaped body 2 in the closed configuration.

In addition, it should be noted that the pivot pin 8 of said at least one sliding latch 4 forms a single piece with the sliding latch 4 and is coupled, with a single degree of freedom of rotation about its own axis, to a wall of the body box-shaped. two.

In the fully retracted configuration of the sliding latch 4, the eccentric projection 9 of the pin 8 is housed in the straight section of the second slot 7 (therefore, outside the recess 10) and substantially aligned with said slot, thus preventing the slide latch turns 4.

In fact, any rotation of the sliding latch is prevented by the fact that this would correspond to an equal rotation of the projection 9 which, however, lies within the straight section of the second slot 7, which cannot change its orientation ( since it is blocked inside said slot 7).

Rotations of the sliding bolt 4 will only be allowed when the projection 9 is aligned with the recess 10, a configuration in which its orientation can be modified following a rotation of the sliding bolt 4 with which it forms a single piece.

The actuating rod 3 can advantageously comprise at least one element 25 for connecting to at least one adapted transmission slider that is coupled, directly or indirectly, to a main lock.

Therefore, through the transmission rods, the assembly 1 can move positively.

It should be noted that an additional function carried out by the projection 14 is to facilitate the exit of the sliding latch 4 (when it is in the fully retracted configuration).

In particular, with reference to the embodiment shown by way of example in the attached figures, the translation of the actuating rod 3 downwards, when the sliding latch 4 is in the fully retracted configuration, causes a descent of the projection 14 that will force it on the outer edge of the intermediate part 23 of the sliding latch 4 (at the other end of said intermediate part 23 with respect to the hole 13).

The thrust exerted by the projection 14 on the edge of the intermediate part (which will have a curvilinear progression adapted so as to separate the force exerted by the projection into a component perpendicular to the edge and a component tangential thereto) will result in the application of a moment in the sliding latch 4, which will cause its rotation with respect to the pin 8 in the direction of the sliding latch 4 exiting with respect to the box-shaped body 2. This first rotation of the sliding latch 4 caused by the projection 14 will cause also a first rotation of the eccentric projection 9 until its partial entry into the recess 10 of the second slot 7. The subsequent descent of the actuating rod 3 will entail a new rotation of the sliding latch 4 until it reaches the extracted configuration, thanks to the rotation exerted on the sliding latch through the eccentric projection 9 which will be oriented through the recess 10.

Advantageously, the present invention solves the problems mentioned above, by providing a peripheral assembly 1 for multipoint locks that prevents intrusion actions intended to force the opposite rotation of the sliding hook-shaped latch 4 for the corresponding retraction.

Indeed, in the closed configuration (sliding latch 4 extracted), the rocker arm 11 is elastically maintained in its own conditions by forcing its head 12 into the hollow 13 of the sliding latch 4, immobilizing it.

Appropriately, the assembly 1 according to the invention guarantees maximum security against forced intrusion actions of the door leaf: this is thanks to the hook-shaped structure of the sliding latch 4, which makes it difficult to extract it from the seat of the door. jamb if you try to force the door leaf open.

Conveniently, the assembly 1 according to the invention is made up of a small number of simple components that are easy to assemble.

In a positive way, the present invention makes it possible to provide a peripheral assembly 1 for multipoint locks that is easy and practical to apply and that has a low cost: said characteristics make the assembly 1 according to the invention an innovation that will certainly be safe in use.

The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Furthermore, all the details can be replaced by other technically equivalent elements.

In the illustrated embodiments, the individual features shown in connection with specific examples may actually be interchangeable with different features existing in other embodiments.

In practice, the materials used, as well as the dimensions, can be any according to the needs and the state of the art.
