Description

LOCK

Technical Field

The present invention relates to a lock for windows/doors such as doors, gates, windows, flaps and the like.

Background Art

Locks are well known provided with fastening devices that have sliding hooks adapted to be be inserted in special seats to tighten two portions of the window/door, e.g. two leaves/shutters to each other, or one leaf/shutter to the frame.

These locks allow closing the window/door by improving the seal of the closure with respect to normal locks, and prevent any attempts to break in with a crowbar.

The patent document IT19710049652 illustrates a lock having a fastening device, associated with a leaf/shutter of the window/door to be closed, provided with two sliding rods moving close to/away from each other.

The two rods have respective hooks adapted to be inserted in housing seats obtained on the other leaf/shutter, in the case of two- shutter window/door, or on the frame, in the case of one-shutter window/door, through an “expansion” mechanism.

With this mechanism, turning the key in one direction, the two rods move away by inserting the hooks in their respective seats, thus causing the lock to close.

By turning the key in the other direction the two rods move away from each other and the hooks are disengaged from their respective seats, resulting in the opening of the lock.

The lock shown uses the movement of the lock rods to form one or more closure hinges along the door rebate, thus making the closure crowbar-proof.

The above mentioned patent document illustrates a solution that could be improved.

In particular, in the face of an increasing demand for security, the need is well known to have locks which can ensure a safe, effective and at the same time practical and fast closure of the window/door. The need is known to close the lock quickly and effectively, both from the outside and from the inside, in order to ensure the highest possible degree of security.

For example, a user who enters the house, once inside, closes the door by pushing the door leaf in and triggering the lock.

This operation allows the closure of the window/door, but it is not enough to ensure the security of the closure.

The handle can be easily releasable by inserting a flexible sheet of paper, e.g. a plate or a credit card, into the slot of the window/door.

Any malicious attackers would have no difficulty in entering from the outside. To ensure the security of the closure it is necessary to turn the key by giving one or more turns so that the latches slide into the locking slots.

This operation is usually carried out at night, from the inside, so as to ensure greater peace of mind for those present who are preparing to go to sleep. However, it happens frequently that this operation is not performed, e.g. because of forgetfulness or because it is considered unnecessary, allowing any malicious intruder to enter the house during the night while the occupants are sleeping.

In general, the operations related to the lock closure by turning the key can be uncomfortable and laborious (key selection, multiple key rotation), sometimes incompatible with the convenience requirements of the users, or required in particular emergency situations.

For example, in the event of an earthquake or fire, the operations required to open a closed lock may be too long and laborious, resulting in risks to people’s safety.

On the other hand, leaving the lock open exposes the user to the risk that malicious intruders may force the lock and get in.

Description of the Invention

The main aim of the present invention is to devise a lock that allows an effective, quick, safe, and practical closure of the window/door.

One object of the present invention is to devise a lock that can also be installed and used on already existing windows/doors.

Another object of the present invention is to devise a lock compatible with particular existing locks, e.g. of the type shown in patent document IT19710049652.

Another object of the present invention is to devise a lock that allows overcoming the aforementioned drawbacks of the prior art in a simple, rational, easy, effective to use and low-cost solution.

The objects set out above are achieved by the present lock having the characteristics of claim 1.

Figures 3, 4 and 5 show, in a sequence of axonometric views of the lock according to the invention, the transition from the opening configuration to the closing configuration;

Figures 6, 7 and 8 respectively show a sectional view of Figures 3, 4 and 5; Figure 9 is an axonometric detailed view of the lock according to the invention. Embodiments of the Invention

With particular reference to these figures, reference numeral 1 globally indicates a lock.

The lock 1 comprises a fastening device 2 positioned on a first portion 3 of a window/door 4 adapted to stop against a second portion 5 of the same window/door.

According to the embodiment of the lock 1 shown in the figures, the window/door 4 is of the type of a double-leaf door. The first portion 3 and the second portion 5 are the door leaves and are hinged to the frame 6.

For simplicity of illustration, the external part of the first portion 3, indicated with reference numeral 7, has been illustrated in exploded view.

Embodiments cannot be ruled out wherein the door has only one leaf.

In this case the first portion 3 would coincide with the leaf/shutter, while the second portion 5 would coincide with the part of the frame 6 adapted to abut against the leaf/shutter itself.

Different solutions cannot however be ruled out wherein the window/door 4 is of the type of a window or is of the type of a wing.

According to the embodiment shown in the figures, the fastening device 2 is associated with the first portion 3, however, further embodiments of the lock 1 cannot be ruled out wherein the fastening device 2 is made at least partly in a single body piece with the first portion 3.

The fastening device 2 is provided with at least one sliding element 8 adapted to slide along a substantially vertical sliding direction 9.

The fastening device 2 also comprises at least one hook 10 associated with the sliding element 8.

In particular, the hook 10 extends along a direction of extension substantially parallel to the sliding direction 9.

Conveniently, the lock 1 comprises at least one fastening seat 11 associated with the second portion 5 of the window/door 4.

Further embodiments of the lock 1 cannot however be ruled out wherein the fastening seat 11 is made at least partly in a single body piece with the second portion 5.

In particular, the fastening seat 11 is obtained in the second portion 5 at the part of second portion 5 adapted to stop against the first portion 3.

The fastening seat 11 is adapted to receive the hook 10 so as to form a closing coupling.

In the embodiment of the lock 1 shown in the figures, the fastening seat 11 defines at least one longitudinal channel 16, inside of which the hook 10 is insertable sliding to size so as to constrain the first portion 3 to the second portion 5 when these stop against each other, thus preventing the opening of the window/door.

Conveniently, the lock 1 comprises at least one control device 12 associated with the fastening device 2 and adapted to lift/lower the hook 10 along the sliding direction 9 to switch from an opening configuration, wherein the hook 10 is released from the fastening seat 11, to a closing configuration, wherein the hook 10 is inserted in the fastening seat 11.

In particular, the control device 12 is adapted to move the sliding element 8 so as to move the hook 10 along the sliding direction 9 accordingly.

According to the invention, the lock 1 comprises at least one automatic movement assembly 17, 18, 20, 21 of the hook 11 from the opening configuration to the closing configuration, provided with: at least one stop portion 17 made on the hook 10; at least one abutment portion 18 of the stop portion 17, made on the fastening seat 11 and adapted to operate in conjunction with the stop portion 17 to automatically move the hook 11 from the opening configuration to the closing configuration.

Advantageously, the hook 10 comprises an end section 19, on which the stop portion 17 is obtained.

In addition, the stop portion 17 and the abutment portion 18 are arranged substantially at the same height with respect to the ground.

This way, during the approach of the first portion 3 to the second portion 5, the stop portion 17 abuts against the abutment portion 18 to allow switching from the opening configuration to the closing configuration.

Preferably, the stop portion 17 is of the type of an inclined surface arranged substantially transverse with respect to the sliding direction 9 to substantially create an invitation plane which is adapted to abut against the abutment portion 18.

This way, the abutment portion 18 slides along the stop portion 17 and forces the latter and the hook 10 to move from the opening configuration to the closing configuration.

In particular, the automatic movement assembly 17, 18, 20, 21 is automatically movable from a transitional configuration, wherein the abutment portion 18 abuts against the stop portion 17 and the hook 10 is moved away from a predefined home height, to a locking configuration, wherein the abutment portion 18 is moved away from the stop portion 17, and the hook 10 is placed at the predefined home height and is in the closing configuration.

In particular, in the opening configuration, the stop portion 17 is arranged at the predefined home height.

Appropriately, the first portion 3 and the second portion 5 are moved away from/close to each other along an opening/closing direction 22 which is arranged substantially transverse with respect to the sliding direction 9.

In addition, in the opening configuration, the stop portion 17 and the abutment portion 18 are arranged along the opening/closing direction 22, as shown in Figures 3 and 6.

This way, when the first and the second portions 3, 5 are brought close to each other, the abutment portion 18 is intended to engage the stop portion 17 and to move the automatic movement assembly 17, 18, 20, 21 in the transitional configuration, as shown in Figures 4 and 7.

Subsequently, bringing the first and second portions 3, 5 closer to each other, the automatic movement assembly 17, 18, 20, 21 is moved from the transitional configuration to the locking configuration, as shown in Figures 5 and 8.

In other words, during the movement from the transitional configuration to the locking configuration, the abutment portion 18 pushes the stop portion 17 along the sliding direction 9 away from the fastening seat 11 so as to force the hook 10 to override the abutment portion 18 and place itself inside the longitudinal channel 16, i.e. in the closing configuration.

In fact, advantageously, the abutment portion 18 is arranged at the perimeter edge of the fastening seat 11 that defines the mouth of the longitudinal channel 16.

This way, the abutment portion 18 and the longitudinal channel 16 are arranged substantially side by side.

Advantageously, the automatic movement assembly 17, 18, 20, 21 comprises elastic means, not shown in the figures, placed between the sliding element 8 and the hook 10 to keep the latter at the predefined home height.

In fact, the hook 10 is associated with the sliding element 8 movably sliding with respect to the latter along the sliding direction 9.

In other words, the hook 10 is movable in a single body piece in translation with the sliding element 8, but it is also movable with respect to the latter.

In fact, during the transition from the opening configuration to the closing configuration, the sliding element 8 is kept fixed along the sliding direction 9. On the other hand, the hook 10 is moved along the sliding direction 9 by the abutment portion 18 and by the elastic means.

In particular, the elastic means are charged in the transitional configuration and are discharged in the locking configuration.

In other words, the elastic means counteract the movement of the hook 10 from the closing configuration to the transitional configuration.

In fact, after overriding the abutment portion 18, the hook 10 is pushed by the elastic means inside the fastening seat 11, so as to ensure the automatic reaching and keeping of the closing configuration.

This way, the elastic means keep the hook 10 at the predefined home height, preventing it from being pulled out of the fastening seat 11, e.g. as a result of vibrations or attempts to tamper with the lock 1.

Preferably, the elastic elements are of the type of a spring positioned between the hook 10 and the sliding element 8.

Conveniently, the automatic movement assembly 17, 18, 20, 21 comprises: at least one locking portion 20 made on the fastening seat 11 substantially opposite the abutment portion 18; at least one retention portion 21 made on the hook 10 substantially opposite the stop portion 17, the locking portion 20 stopping against the retention portion 21 in the closing configuration to prevent the movement of the hook 10 in the opening configuration. Preferably, the locking portion 20 and the retention portion 21 are of the type of a straight section that extends substantially parallel to the sliding direction 9. Advantageously, the stop portion 17 is made on the end section 19.

The retention portion 21, on the contrary, coincides with the internal wall of the fastening seat 11 defining the longitudinal channel 16.

In particular, in the locking configuration, the locking portion 20 and the retention portion 21 are arranged stopped to each other and prevent the first portion 3 from moving away from the second portion 5 along the opening/closing direction 22, i.e. the transition from the locking configuration to the transitional configuration.

Consequently, the locking portion 20 and the retention portion 21, operating in conjunction with the elastic means, prevent the movement of the hook 10 from the closing configuration to the opening configuration.

In other words, the stop portion 17, the abutment portion 18, the locking portion 20, the retention portion 21 and the elastic means define a latch mechanism.

In fact, the movement of the hook 10 from the closing configuration to the opening configuration takes place only by means of the control device 12. Advantageously, the fastening device 2 comprises at least one guiding member 25 of the hook 10.

In particular, the hook 10 is coupled movable in a sliding manner to the guiding member 25 along the sliding direction 9.

Preferably, the guiding member 25 is made on the first portion 3 and defines a transit channel 26 wherein the hook 10 is movable in a sliding manner.

In addition, the guiding member 25 is moved away from the fastening seat 11 in the opening configuration and is approached to the fastening seat 11 and aligned to the latter in the closing configuration.

This way, the guiding member 25 allows improving the sliding of the hook 10, thus avoiding displacements that, over time, would cause malfunctions and deformations of the lock 1.

Advantageously, the end section 19 extends protruding from the outside of the guiding member 25. As a result, the stop portion 17 protrudes from the outside of the guiding member 25.

In fact, the hook 10 is arranged to pass through the transit channel 26.

This way, when the guiding member 25 is approached the fastening seat 11, the stop portion 17 abuts against the abutment portion 18 and slides away from the predefined home height guided by the transit channel 26.

In addition, in the closing configuration, the transit channel 26 keeps the hook 10 aligned with the longitudinal channel 16 and ensures the transition of the hook itself from the opening configuration to the closing configuration. Preferably, the guiding member 25 and the fastening seat 11 are of the type of two half hinges attached to the first portion 3 and to the second portion 5, respectively.

This way, when the hook 10 is in the closing configuration, i.e. when it is inserted inside the longitudinal channel 16 and the transit channel 26, it defines with the guiding member 25 and the fastening seat 11 a complete hinge that prevents the lock 1 from opening.

Advantageously, in the closing configuration, the hook 10 can be further inserted inside the fastening seat 11 by means of the control device 12.

In fact, the control device 12 comprises turning means adapted to move the hook 10 between the predefined home height and at least one predefined turning height.

In particular, the hook 10 extends more inside the fastening seat 11 when it is placed at the predefined turning height with respect to when it is placed at the predefined home height.

In other words, the turning means are adapted to move the hook 10 deep along the fastening seat 11 in order to improve the seal of the lock 1 in the closing configuration.

In addition, the turning means are adapted to move the hook 10 at a plurality of predefined turning heights arranged at different depths inside the fastening seat 11.

In particular, the turning means are adapted to move the sliding element 8 so that the hook 10 can be moved accordingly along the sliding direction 9. Advantageously, the turning means comprise at least one internal mechanism of known type, not shown in the figures, which is associated with the sliding element 8 and adapted to raise/lower the sliding element itself.

Preferably, the turning means are of the type of a cylinder 15 in which a key 14 can be inserted adapted to operate in conjunction with the cylinder 15 to raise/lower the sliding element 8 depending on the rotation that is impressed on the key itself.

Other solutions involving box-shaped bodies with known internal mechanisms, which are part of the state of the art, cannot also be ruled out.

Conveniently, the control device 12 comprises unlocking means which are adapted to move the hook 10 from the predefined home height and/or from the predefined turning height to an unlocking height, at which the hook 10 is disengaged from the fastening seat 11 , the unlocking means moving the sliding element 8 to move the hook 10.

In particular, the unlocking means are adapted to move the sliding element 8 and consequently the hook 10.

In fact, the unlocking means are adapted to move the sliding element 8 along the sliding direction 9 in order to move the hook 10 away from the predefined home height and/or from the predefined turning height and pull it out of the fastening seat 11.

This way, the hook 10 is moved from the closing configuration to the opening configuration and the first portion 3 and the second portion 5 can be moved away from each other.

In other words, the unlocking means allow moving the hook 10 (as a result of the movement of the sliding element 8) from the closing configuration to the opening configuration both in the event of the hook 10 being placed at the predefined home height and in the event of the hook 10 being placed at the predefined turning height.

Preferably, the unlocking means are associated with the turning means.

In other words, the unlocking means can be operated using the key 14 and the cylinder 15 used to operate the turning means.

Conveniently, the control device 12 comprises operating means 23 of the unlocking means.

Preferably, the operating means 23 are of the type of a gripping element, e.g. of the type of a handle, a knob or the like, which can be operated manually by a user to move the sliding element 8 so as to move the hook 10 from the predefined home height and/or from the predefined turning height to the predefined unlocking height and to move the first and the second portion 3, 5 away.

This way, the user does not have to use the key 14 to move the hook 10 from the closing configuration to the opening configuration.

Moreover, the control device 12 comprises at least one elastic unit operating on the sliding element 8. In particular, the elastic unit is discharged when the hook 10 is placed at the predefined home height, and is at least partly charged when the hook 10 is placed at the predefined unlocking height, tending to move the sliding element 8 in order to place the hook 10 at the predefined home height. This way, as a result of the operation of the unlocking means, the elastic unit automatically returns the hook 10 to the predefined home height. For example, once the handle is released, the elastic unit automatically returns the hook 10 to the predefined home height.

Appropriately, with reference to the embodiment of the lock 1 shown in the figures, wherein the lock itself is mounted on a door, e.g. as an armored door of a house, the operating means 23 are associated with the first portion 3 and turned inside the house.

This way, the user must operate on the operating means 23 to leave the house and must operate on the cylinder 15 using the key 14 to access the house.

With particular reference to the embodiment of the lock 1, the fastening device 2 comprises: two sliding elements 8; a plurality of hooks 10, at least two of which being associated with different sliding elements 8; a plurality of fastening seats 11, each of which being adapted to receive in engagement a respective hook 10 in the closing configuration; a plurality of automatic movement assemblies 17, 18, 20, 21, each of which being made at one respective hook 10 and one respective fastening seat 11. More in detail, a first sliding element 8 is associated with a hook 10 facing downwards, i.e. a hook 10 that extends approaching the ground to fit into a corresponding fastening seat 11 below.

A second sliding element 8, on the other hand, is associated with two hooks 10 facing upwards, i.e. two hooks 10 extending away from the ground to fit into two corresponding fastening seats 11 above.

Appropriately, the lock 1 comprises a fastening seat 11 for each hook 10 which is associated with the sliding elements 8.

Additional embodiments of the lock 1 cannot however be ruled out wherein the lock comprises a different number of hooks 10 and of fastening seats 11.

In addition, the lock 1 comprises three automatic movement assemblies 17, 18, 20, 21 arranged at each hook 10 - fastening seat 11 pair, respectively. Advantageously, the sliding elements 8 are fitted into the control device 12, which is preferably of the type of an expansion control device.

This way, the sliding elements 8 slide away from each other or approaching each other depending on whether you want to open or close the lock.

The operation of the present invention is as follows.

In a normal closing operation of the window/door 4, the first portion 3 is stopped against the second portion 5.

As long as the first portion 3 does not stop, the hook 10 remains in the opening configuration and is kept at the predefined reference height by the elastic means, as shown in Figure 3 and 6.

When the portions 3 and 5 come to a stop, the stop portion 17 comes into contact with the abutment portion 18, thus moving the hook 10 away from the predefined home height, and the automatic movement assembly 17, 18, 20, 21 is moved to the transitional configuration, as shown in Figure 4 and 7.

This way, the hook 10 overrides the abutment portion 18, reaches the fastening seat 11 and is pushed inside the longitudinal channel 16 by the elastic means, moving automatically to the closing configuration, as shown in Figure 5 and 8. In particular, in this configuration, the first and second portions 3, 5 are coupled together to close the door without the possibility of being uncoupled. In fact, in this configuration, the hook 10 extends inside the fastening seat 11 and is locked inside by means of the locking portion 20 and the retention portion 21.

When this configuration is reached, the lock 1 is closed and the first and second portion 3, 5 are locked. Therefore, to bring the hook 10 back to the opening configuration, it is necessary to work on the unlocking means.

Alternatively, when the closing configuration has been reached, the user can work on the turning means to place the hook 10 deeper inside the fastening seat 11 at the predefined turning height, i.e. to make the closure of the lock 1 more secure.

Consequently, to return to the opening configuration, it is first necessary to return the hook 10 to the predefined home height by means of the turning means and then to permanently pull the hook 10 out of the fastening seat 11 by means of the unlocking means. It has in practice been ascertained that the described invention achieves the intended objects and, in particular, the fact is emphasized that the lock allows an effective, fast, safe and practical closure of the window/door.

In particular, the automatic movement assembly allows the lock to be closed automatically as soon as one leaf/shutter stops against the other leaf/shutter or against the frame.

This eliminates the need for manual closing operations.

Similar considerations may be made for the opening of the window/door, so it is sufficient to operate on the unlocking means to instantly release the hooks and keep them in the opening configuration, not requiring manual opening operations needing the fitting and turning of one or more keys or other laborious maneuvers. This way, both closing and opening operations are greatly simplified, which benefits the speed of execution and, therefore, safety in case of a disaster.

All this without compromising the security of the lock which, thanks to the fitting of the hooks in their respective seats, remains burglar-proof. In particular, due to the vertical arrangement of the hooks, it is impossible to tamper with the lock by inserting a flexible sheet into the window/door slot, such as e.g. a plate or a credit card.

Moreover, the lock devised can be installed and used on already existing windows and doors. This way it is possible to simplify the working operations for pre-existing windows and doors and already provided with locks such as, e.g., the one described in patent document IT19710049652.

The lock devised is an evolution of the lock described in the above mentioned patent document, and allows an automatic locking by means of a mechanical system.

Thanks to the lock devised, the use of the key is necessary only for the openings from the outside of the window/door, e.g. when a user needs to enter the house. To close the lock, it will be enough to push the door in, with the hooks that will automatically slide into their respective seats. To reopen the door there is no need to use the key, but it is enough to work on the operating means of the unlocking means by automatically lifting so that the door/window can be opened.

This way security is ensured, since the lock is burglar-proof.

In addition, it is not necessary to leave the key in place to bring the lock to the closing configuration.

Therefore, each time the door is closed, maximum security will be ensured without necessarily using the key, thus facilitating access to more people without having to turn the key or leave it in place.
