Description

Door closing lock with highly flexible use

Detailed Description

The present invention relates to a locking door lock with a highly flexible use.

In the prior art, door closures with various functions depending on the use are known, which can be used in particular for doors of buildings suitable for access by a predefined set of people, as well as doors of buildings, management buildings, schools, hotels, warehouses and offices open to the public.

One of the main functions is in particular the possibility of disabling the outer handle of the door or window, the possibility of driving both the bolt and the bolt of the lock by means of a key only or by means of the inner handle of the door or window.

Generally, door locks are made with all or almost all intentionally dedicated mechanical parts, depending on the function for which they are intended.

In order to be able to manufacture a series of locking locks, the manufacturer finds itself forced to provide a very large number of product codes, which obviously considerably complicates the management of the warehouse inventory and has a non-trivial impact on the final costs.

The technical task of the present invention is therefore to produce a closer lock that makes it possible to eliminate complaints about the technical drawbacks of the prior art.

In the context of this technical task, one object of the present invention is to make a closer lock suitable for being implemented with different functions without modifying its basic configuration.

The technical task, as well as these and other objects, according to the present invention are achieved by making a closer lock for doors or windows comprising a casing, a translatable bolt supported by a support plate provided with a slot, a translatable bolt, a slot for introducing a key, a cylinder having a pawl rotatable by said key to move said bolt, a rotatable element for driving said bolt, a cam present on said rotatable element for driving said bolt, a movement receiver and distributor comprising at least one first rotatable plate pivoted on said casing, said first plate comprising a first shaped perimetric receiving profile for receiving said movement from said pawl, a second shaped perimetric receiving profile for receiving said movement from said cam, and a pulling mechanism of said bolt slidable in said slot, the slot has a shaped intermediate portion for reversibly moving the bolt by means of the pulling mechanism, a first end portion and a respective second end portion for locking the bolt by means of the pulling mechanism in an extracted end-stroke position and a respective retracted end-stroke position out of/into the housing, further providing an elastic pushing element which pivots on the housing and interacts with the first plate to assist in reaching the end-stroke position.

The receiver and dispenser enable the closer lock to perform the basic function of a combined actuation of the bolt and bolt for actuating the bolt by means of a grip on the rotatable element operating from the inside of the door or window.

Advantageously, a closer lock with the basic features described above can be realized with additional components to perform different functions.

In one embodiment of the invention, the closer lock comprises a longitudinal lever for retracting the bolt, the longitudinal retraction lever having a first end constrained on the rotatable element for driving the bolt and a second end longitudinally opposite to the first end having a peripheral receiving profile for receiving the movement from the pawl.

The retraction lever for retracting the latch makes it possible to actuate the latch by means of a key.

In one embodiment of the invention, the lock comprises an inner rotor securely constrained by the rotatable element for driving the bolt and having an engagement seat for driving a square pin of the bolt from the inside of the door or window; an outer rotor having an engagement seat for driving a square pin of the door latch from outside the door or window; a transmission lever interacting with the movement receiver and dispenser for switching between a connected state and a disconnected state of the outer rotor and the rotatable element for driving the door latch.

The separation of the square pin and the rotor with the engagement seat of the square pin and the provision of the transmission lever make it possible to enable and disable the function of the external grip (for example, the handle or knob provided for driving the bolt from the outside of the door or window).

Advantageously, the movement distributor and receiver provide a second rotatable plate that interacts with the transmission lever to switch the state of the transmission lever when enabling and disabling the function of the outer grip.

Advantageously, the second plate may be configured and arranged to automatically perform the function of enabling or disabling the outer grip when the bolt is withdrawn, or at the request of the outer grip.

Advantageously, the second plate may be configured to perform the enabling and disabling functions by a full turn of the key or by a partial turn of the key at the request of the outer grip to prevent withdrawal of the key when the outer grip is enabled.

In one embodiment of the invention, in the field of two-wing doors and windows, the closing lock comprises an extraction plate of the pulling mechanism for extraction from the first end portion of the slot, parallel to the support plate, facing and translatable parallel to the support plate, and having a projection positionable in front of the bolt for receiving the movement and a slot in which the pulling mechanism can slide.

The provision of the extraction plate of the pulling mechanism makes it possible to release the function of the bolt from the extraction end-stroke position by the action of a thrust force from the outside, received on the projection for receiving the movement from the opening control element positioned on the second wing.

Other features of the invention are further defined in the following claims.

Equivalent parts of the various door latch versions will be indicated by the same reference numerals.

With reference to the cited figures, there is shown a door or window closing lock, indicated as a whole by the reference numeral 1.

As will become more apparent below, the present invention provides a basic mechanism that is common to all locks.

Various lock types incorporate basic mechanisms and additional components for performing their assigned functions.

The door closer 1 comprises a housing 2 having a substantially parallelepiped configuration formed by a box 2a and a cover 2b, wherein the box 2a defines a first flat side 2c of the housing 2, a flat rear side 2d of the housing 2, an upper flat plane 2e and a lower flat plane 2f of the housing 2, and the cover 2b defines a second flat side 2g of the housing 2 parallel to the first flat side 2 c.

The cartridge 2a and the cover 2b define, in combination, finally a front side 2h of the casing 2.

The housing 2 can be accommodated in a seat which is open on the front side of the door or window and which penetrates into the thickness of the door or window (not shown) in the front-rear direction.

In a known manner, the casing 2 houses the bolt 3 and the bolt 6 and has a housing seat 34 for a cylinder (not shown overall) provided with a rotatable pawl 7 for driving the bolt 3 and a slot (not shown) for introducing a key (not shown) to drive the pawl 7.

In a known manner, the bolt 3 translates in the front-to-rear direction of the casing 2 between a position extracted from the casing 2 through a window provided on the front side 2h of the casing 2 and a position fully retracted into the casing 2.

In particular, the bolt 3 is supported in a fixed manner by a support plate 4, which is coupled in a translatable manner with the casing 2 by means of suitable linear guides comprising a longitudinal slot 35 of the support plate 4 engaged by a guide pin 36 fixed in the casing 2.

The support plate 4 is flat and arranged parallel to the

flat sides

2c, 2g of the housing 2.

In a known manner, the bolt 6 also translates in the front-to-rear direction of the casing 2 between a position extracted from the casing 2 through a window provided on the front side 2h of the casing 2 and a position completely retracted into the casing 2.

In particular, the bolt 6 is supported in a fixed manner to the head of a rod 37 which can be translated in opposition and is acted upon by a spring 38, in particular a torsion spring 38, which pivots on the casing 2 and has a driving arm which engages a flange 39 of the tail of the rod 37 and a reaction arm which rests on the inner wall of the casing 2.

The closer lock 1 provides a rotatable element 8 for driving the bolt 6.

The driving element 8 for driving the bolt 6 is formed by a shaped plate pivoted on the casing 2, having an axis of rotation orthogonal to the

sides

2c, 2g of the casing 2.

The driving element 8 for driving the bolt 6 has a ridge 45 for driving the bolt 6, which ridge 45 engages the side of the flange 39 of the tail of the rod 37 opposite to the side engaging the torsion spring 38.

On the opposite side of the rotatable element 8 for driving the bolt 6, an inner rotor 27 is positioned, having an engagement seat 46 for driving a square pin (not shown) of the bolt 6 from the inside of the door or window, and an outer rotor 27 'having an engagement seat 46' for driving a square pin (not shown) of the bolt 6 from the outside of the door or window. The inner rotor 27 and the outer rotor 27' are rotatable coaxially with the rotatable element 8.

In particular, the inner rotor 27 and the outer rotor 27' can be rotated reciprocally by the action of the elastic means 47 between two end positions defined by two

end strokes

70, 71 fixed in the casing 2.

The engagement seats 46, 46 'of the square pins are centred on the common axis of rotation of the inner rotor 27 and of the outer rotor 27'.

The inner rotor 27 is fixed to the rotatable element 8 and the outer rotor 27' may or may not also be fixed to the rotatable element 8, depending on the application.

If the inner rotor 27 and the outer rotor 27' are firmly constrained by the rotatable element 8, for example, locking posts 49 are provided which fixedly join the three parts together.

On the other hand, if only the inner rotor 27 is firmly constrained by the rotatable element 8, a locking screw 48 is provided, for example, which fixedly joins the two parts together.

In some versions of the lock, the square pin for driving the bolt 6 from the inside and the outside of the door or window can be made of a single piece, in other versions of the lock, the square pin for driving the bolt 6 from the inside and the outside of the door or window is on the other hand structurally separate and independent.

The rotors 27 and 27' may be located differently inside or outside, depending on the orientation of the bolt 6 (rotated 180 °). Conventionally, the inner rotor is indicated by the number 27 and the outer rotor is indicated by the number 27'.

Advantageously, the locking door 1 also provides a movement receiver and dispenser comprising at least one rotatable first plate 10 pivoted on the casing 2.

The first plate 10 comprises a first shaped perimetric receiving profile 12 for receiving the movement coming from the pawl 7, a second shaped perimetric receiving profile 13 for receiving the movement coming from the cam 9 present on the element 8 for driving the bolt 6, and a pulling mechanism 14 for pulling the bolt 3, slidable in the slot 5 of the bolt 3.

The pulling mechanism 14 is more precisely in the form of a pin fixed orthogonally to the first plate 10.

The second receiving contour 13 more precisely comprises a convex corner of the peripheral edge of the first plate 10.

The first plate 10 is interposed between the pawl 7 and the rotatable element 8 for driving the bolt 6.

In particular, the first plate 10 has a flat elongated configuration, is arranged parallel to the

flat sides

2c, 2g of the casing 2, and is pivoted on the casing 2 by an axis of rotation orthogonal to the

sides

2c, 2g of the casing 2.

More precisely, the first plate 10 is interposed between one of the two

flat sides

2c, 2g of the casing 2 and the support plate 4 of the door bolt 3.

The elongated configuration of the first plate 10 is such that the distance of the pulling mechanism 14 from the rotation fulcrum 16 of the first plate 10 is greater than the maximum between the distances of the first and second receiving profiles 12,13 from the rotation fulcrum 16 of the first plate 10.

The slot 5 of the bolt 3 has: an intermediate portion 5a shaped for reversibly moving the bolt 3 by means of the pulling mechanism 14; a first end portion 5b shaped for locking the bolt 3 in an end-stroke position for extraction from the housing 2 by means of the pulling mechanism 14; and a second end portion 5c shaped for locking the bolt 3 in an end-stroke position for retraction from the housing 2 by means of the pulling mechanism 14.

The slot 5 has an inclined middle portion 5a and

end portions

5b,5c inclined in the opposite direction to the inclined middle portion 5 a.

The locking door 1 also provides an elastic pushing element 11 which pivots on the casing 2 and interacts with the first plate 10 to help reach the end-stroke position of the bolt 3.

In a preferred embodiment, the elastic pushing element 11 is linear and has a stress axis coplanar with the first plate 10.

When the bolt 3 moves between its end-stroke positions, the stress axis of the elastic pushing element 11 swings from one side to the other of the straight lines joining the elastic pushing element 11 and the

rotation fulcrum

15,16 of the first plate 10.

The stress axis of the elastic thrust element 11 at the end travel position of the bolt 3 is substantially at the same distance from the fulcrum 16 of rotation of the first plate 10.

The elastic thrust element 11 comprises a helical spring 17 and a rod 18 slidingly engaged in a diametric hole 19 of a rotation pin 20, which also defines the fulcrum 15 of the thrust element 11. The stem 18 has a head 18a which is permanently engaged in a seat 21 provided on the peripheral edge of the first plate 10.

The spring 17 is wound around the rod 18 and is compressed between the head 18a of the rod 18 and the rotation pin 20.

The particular arrangement and configuration of the elastic thrust element 11 enables the application of a rotation force permanently coplanar with the first plate 10.

Thus, the first plate 10 is not subjected to torsional stresses which, if present, could alter the lying plane of the first plate 10, thus leading to the risk of failure of the door latch 1.

During the rotation of the first plate 10 by means of the pawl 7 engaging with the first profile 12, the elastic pushing element 11 can assist the action of the pawl 7.

Furthermore, when the elastic pushing element 11 reaches the position of the first plate 10 corresponding to the end stroke position of the bolt 3, the elastic pushing element 11 is able to keep the first plate 10 in the reached position to avoid unwanted movement of the bolt 3.

To assist the disengagement of the pawl 7 from the first shaped perimeter receiving profile 12 of the first plate 10, the door closure 1 has a flexible mechanism 40 hinged on the support plate 4 of the bolt 3, which disengages the pawl 7 from the perimeter recess 12 of the first plate 10.

In particular, the flexible mechanism 40 is shaped as an "S" shaped plate, with a pivot 40' that pivots in a hole 60 of the support plate 4 of the bolt 3 and a tooth 40 "that engages the pawl 7.

The pawl 7 also engages and flexes the flexible mechanism 40 when it engages the first shaped perimeter receiving profile 12 of the first plate 10. Then, in the step of disengaging the pawl 7 from the first shaped perimeter receiving profile 12 of the first plate 10, the elastic energy accumulated by the flexible element is returned to the pawl 7 through the flexible mechanism 40, so as to facilitate the disengagement of the pawl 7 from the first shaped perimeter receiving profile 12 of the first plate 10.

The basic mechanism shown up to now is common to all versions of the door latch 1.

With reference to fig. 7a and 7b, the double-wing door or window version provides an additional component with respect to the basic mechanism formed by a draw-out plate 22 for drawing out the pulling mechanism 14 from the first end portion 5b of the slot 5.

The extraction plate 22 has a projection 23 which can be positioned in front of the bolt 3 for receiving the movement and a slot 24 in which the pulling mechanism 14 can slide.

The extraction plate 22 is flat and arranged parallel to the support plate 4, and on the side of the support plate 4 opposite to the side facing the first plate 10.

The extraction plate 22 is supported by the support plate 4 in a translatable manner in the same direction of translation as the support plate 4.

The slot 24 of the extraction plate 22 has a middle portion 24a identical to the middle portion 5a of the slot 5 of the support plate 4 and a first end portion 24b different from the first end portion 5b of the slot 5 of the support plate 4.

When the projection 23 is in the position of extraction forward from the bolt 3, the first end portion 5b of the slot 5 and the first end portion 24b of the slot 24 intersect, although partially staggered, and the pulling mechanism 14 is positioned through the intersection between the first end portion 5b of the slot 5 and the first end portion 24b of the slot 24.

When the projection on the other hand 23 is in the retracted position in the bolt 3, the middle portion 5a of the slot 5 and the middle portion 24a of the slot 24 are perfectly aligned and traversed by the pulling mechanism 14.

If a door closing device (not shown) present on the second wing commands the door to open, a suitable ejector present in the device located at the bolt 3 is pushed outwards to exert a retraction force directly on the projection 23, thereby retracting the bolt 3 inside.

Selective translation of the extraction plate 22 with respect to the support plate 4 produces a perfect alignment between the intermediate portions 5a of the slots 5 and the intermediate portions 24a of the slots 24, which are initially partially staggered, and, by virtue of the engagement of the walls of the slots 24 with the pulling mechanism 14, produces an oscillation of the first plate 10, due to which the pulling mechanism 14, initially positioned in the first end portion 5b of the slot 5 and in the first end portion 24b of the slot 24, moves to the intermediate portions 5a of the slots 5 and to the intermediate portions 24a of the slots 24.

Once the pulling mechanism 14 has been extracted from the first end portion 5b of the slot 5 and the first end portion 24b of the slot 24, the ejector (which is not shown) continues its stroke, exerting a retraction force directly on the front face of the bolt 3.

With reference to fig. 2a to 2b, the version of the closer lock 1 with the function of recalling the bolt 6 by key provides, with respect to the basic mechanism, an additional component formed by a longitudinal lever 25 for retracting the bolt 6, having a first end constrained on the rotatable element 8 for driving the bolt 6 and a second end longitudinally opposite to the first end, having a peripheral profile 26 for receiving the movement from the pawl 7.

The longitudinal lever 25 for retracting the bolt 6 is in turn formed by a flat plate parallel to the first plate 10 and positioned between the latter and one of the

flat sides

2c, 2g of the casing 2.

The longitudinal lever 25 for retracting the bolt 6 pivots more precisely on the rotatable element 8 for driving the bolt 6 and has a swing angle limited, for example, by suitable interference surfaces.

The axis of oscillation of the longitudinal lever 25 for retracting the bolt 6 is parallel to the axis of rotation of the rotatable element 8 for driving the bolt 6.

In this version of the lock, locking posts 49 are used to constrain inner rotor 27 and outer rotor 27' by rotatable element 8.

In summary, when the pawl 7 is actuated by the key, in addition to engaging and rotating the first plate 10 that controls the retraction of the bolt 3, the pawl 7 engages and actuates the longitudinal lever 25 which in turn transmits the movement to the rotatable element 8 which finally retracts the bolt 6.

With regard to the presently disclosed function, the closer lock 1 has no grip for driving the bolt from the outside of the door or window.

With reference to fig. 3a to 3c, 4a to 4c, 5a to 5b, the version of the closer lock 1 with the function of enabling or disabling the grip operating on the outside of the door or window also provides, with respect to the basic mechanism, a transmission lever 28 which interacts with the movement receiver and distributor for switching between a connected state and a disconnected state of the outer rotor 27' and the rotatable element 8 for driving the door bolt 6.

In this version of the lock, a locking screw 48 is used which secures the only inner rotor 27 to the rotatable element 8 for driving the bolt 6.

The transmission lever 28 is pivoted by a rotation pin 50 on the rotatable element 8 for driving the bolt 6 and is normally kept in the open condition by the elastic element 29.

In particular, the transmission lever 28 comprises two identical curved

flat strips

28a, 28b, fixed to each other and aligned at a distance, with the rotatable element 8 for driving the bolt 6 interposed therebetween in the thickness direction.

By the action of the state switch of the transmission lever 28, the end 28 'of the transmission lever 28 longitudinally opposite to the transmission lever 28 pivoted on the rotatable element 8 for driving the door latch 6 is moved between the interference position and the non-interference position with respect to the trajectory of the engagement seat 51 provided on the outer rotor 27'.

Only when the transmission lever 28 engages the counter-seat 51 can the external rotor 27' rotate the rotatable element 8 in a firmly constrained manner during the rotation stroke to drive the bolt 6.

The angular position of the transmission lever 28 to which the connected state and the disconnected state correspond is precisely identified by a suitable end stroke of the rotary rod 28.

More precisely, the end rotation stroke is formed by a first pin 52 and a second pin 53 fixed to the transmission lever 28 and adapted to interact with stop surfaces 54, 55 obtained peripherally on the rotatable element 8 for driving the bolt 6.

In the solution shown, the elastic element 29 is a helical spring held in an axially compressed state between the second end-stroke pin 53 and the bottom of a slit 56 which opens on the periphery of the rotatable element 8 for driving the bolt 6.

Advantageously, in these lock versions, the mobile distributor and receiver also comprise a second

rotatable plate

30,30',30 "interacting with the transmission lever 28 to switch its state.

The

second plate

30,30',30 "has on the periphery a

cam

31,31', 31" for actuating the transmission lever 28.

In particular, the

second plate

30,30',30 "is flat and parallel to the first plate 10.

Furthermore, the

second plate

30,30',30 "has the same rotational pivot as the first plate 10.

The

second plate

30,30',30 "can oscillate with respect to the first plate 10, in contrast and by the action of the

elastic elements

32,32', 32".

The

second plate

30,30',30 "is positioned to interact directly with the bar 28a facing the side on which the inner rotor 27 of the rotatable element 8 for driving the bolt 6 is positioned.

With particular reference to fig. 3a to 3c, the locking door 1 automatically enables and disables a grip operating on the outside of the door or window.

In practice, the grip operating on the outside of the door or window is automatically disabled by the extraction movement of the bolt 3 and enabled by the retraction movement of the bolt 3.

Starting from the condition shown in figure 3b, in which the bolt 3 is ejected and the transmission lever 28 is in the open position, when the user inserts the key into the cylinder of the lock and rotates it in a full rotation in the direction required to retract the bolt 3, the pawl 7 engages the first plate 10 and rotates the first plate 10 (in the anticlockwise direction in figure 3 b) to command the retraction of the bolt 3, the first plate 10 in turn rotates in the same direction as the second plate 30, and the cam 31 of the second plate 30 rotates the transmission lever 28 until introducing the alignment of the end 28' of the latter on the opposite engagement seat 51. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is actually transmitted to the rotatable element 8 for driving the door latch 6. When the user inserts the key again in the cylinder of the lock and rotates the key in the opposite direction required to extract the bolt 3 in a full rotation, the pawl 7 engages the first plate 10 and rotates the first plate 10 (in the clockwise direction in fig. 3 c) to command the extraction of the bolt 3, the first plate 30 in turn rotates in the same direction as the second plate 30, and the cam 31 of the second plate 30 rotates the transmission lever 28 in the opposite direction to the previous one, until the disengagement of the second plate 30 from the counter-abutment 51 is introduced. At this time, if the user rotates the outer grip, the command from the outer rotor 27' is not transmitted to the rotatable element 8 for driving the door latch 6.

With particular reference to fig. 4a to 4c, 5a to 5b, the closer lock 1 provides for the optional enabling and disabling of a grip operating on the outside of the door or window.

The second plate 30',30 "has a peripheral profile 33', 33" for receiving the movement directly from the pawl 7.

The plates 30',30 "are selectively rotatable with respect to the first plate 10.

The maximum allowable dimension of such selective rotation of the second plate 30',30 "with respect to the first plate 10 is defined by the length of the slot 58', 58" in the form of an arc in which the stop 57 is slidable, the arc having a centre on the common axis of rotation of the first and

second plates

10,30 ',30 ".

In the specific case, the stop 57 is formed by a pin fixed to the first plate 10 and the slots 58', 58 "are formed on the second plate 30', 30", or vice versa.

The closer lock 1 shown in fig. 4a to 4c provides for the optional enabling and disabling of a grip operating on the outside of a door or window by a full rotational rotation of the key in the cylinder of the lock.

Starting from a condition in which the bolt 3 is already in the retracted position and the transmission lever 28 is in the open position, when the user inserts the key into the cylinder of the lock and rotates it in a full rotation in the same direction as required to retract the bolt 3, the pawl 7 does not engage the first plate 10, but only the second plate 30' which can be selectively rotated with respect to the first plate 10 which remains stationary. The cam 3 of the second plate 30 'rotates the transmission lever 28 until introducing the alignment of the end 28' of the latter with respect to the engagement seat 51. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is actually transmitted to the rotatable element 8 for driving the door latch 6. When the user inserts the key again in the cylinder of the lock and rotates the lock in the opposite direction required to extract the bolt 3 in a complete rotation, the pawl 7 engages the second plate 30' and rotates it in the opposite direction to the previous one, and the cam 3 of the second plate 30' rotates the transmission lever 28 in the opposite direction to the previous one, until the disengagement of the second plate 30' from the opposite engagement seat 51 is introduced. At this time, if the user rotates the outer grip, the command from the outer rotor 27' is not transmitted to the rotatable element 8 for driving the door latch 6.

The closer lock 1 shown in fig. 5a to 5b provides for the random enabling and disabling of a grip operating on the outside of the door or window by rotation less than a full turn of the key in the cylinder of the lock to prevent the key being withdrawn when the grip operating on the outside of the door or window is enabled.

The main differences with respect to the previously disclosed versions of the closer lock include limiting the maximum angle of rotation of the permitted plate 30 "with respect to the first plate 10. Plate 30 "has the same configuration as plate 30', and the length of slot 58" is less than the length of slot 58'.

Starting from a condition in which the bolt 3 is already in the retracted position and the transmission lever 28 is in the open position, when the user inserts the key into the cylinder of the lock and rotates the lock in a partial rotation in the direction required to retract the bolt 3, the pawl 7 does not engage the first plate 10, but only the second plate 30 "which can be selectively rotated with respect to the first plate 10 which remains stationary. At the end of the rotation, which is more limited than that previously shown, the cam 31 "of the second plate 30" still rotates the transmission lever 28 until introducing the alignment of the end 28' of the latter with respect to the engagement seat 51. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is actually transmitted to the rotatable element 8 for driving the door latch 6. In this case, the key remains confined in the cylinder of the lock. When the user rotates the key in a partial rotation in the opposite direction required to extract the bolt 3, the pawl 7 engages the second plate 30 "and rotates the second plate 30" in the opposite direction to the previous one, and the cam 31 "of the second plate 30" rotates the transmission lever 28 in the opposite direction to the previous one, until its disengagement from the opposite engagement seat 51 is introduced. At this point, the key is free and can be extracted from the cylinder of the lock, and if the user rotates the outer grip, the command from the outer rotor 27' is not transmitted to the rotatable element 8 for driving the bolt 6.

It is clear that the version of the door latch shown in figures 4a to 4c and 5a to 5b must provide the

springs

17, 32',32 "with structural and mechanical characteristics, in particular stiffness, in order to allow selective movement of the second plate 30', 30" with respect to the first plate 10. Of course, several of those disclosed functions that are compatible with one another can be implemented modularly in the same closer lock.

For example, the type of locking door for a double-wing door or window is compatible with all other functions disclosed above.

The closer lock as conceived herein is susceptible of numerous modifications and variations, all falling within the scope of the inventive concept; moreover, all the details may be replaced with technically equivalent elements.

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