INDEPENDENT AUXILIARY LOCK DEVICE

DESCRIPTION

TECHNICAL FIELD OF THE INVENTION

The present invention relates to an independent auxiliary lock device configured to lock the opening of a door or window automatically, that is to say, without the need to be actuated by a main lock device; said device being applicable in the sector of locksmithing and hardware.

The auxiliary lock device is intended for the automatic closing of doors or windows, once it is coupled to its respective frame; to prevent its opening even when the lock of the device object of the invention is moved outside the frame of the door or window, further preventing the lock is forced from outside and only, and through a key lock, the door or window can be opened; and turn it by means of an auxiliary lock device formed by a reduced number of elements that collaborate with the main lock for unlocking the door or window; suitable for installation in most existing windows or doors on the market; simple installation, maintenance and replacement; and which has a design of components that guarantee the locking and closing of the door or window without the possibility of being unlocked even by moving the lock of the lock device object of the invention.

BACKGROUND OF THE INVENTION

By way of introduction, in order to obtain the function of automatic closure, it is generally necessary to have a mechanism for establishing a closure sequence in which a hook or lever, configured to lock the door or window, acts only when a trigger device is actuated beforehand, by the contact of the latter with the frame of the door or window.

And where there are currently various devices in which this operational sequence is obtained by means of intermediate retentions which hold the hook or the lever recessed until the door reaches its final position of closure in the frame, so that this lever remains opposite the corresponding hollow of the frame of the door or window.

See for example the patent application number 200702930, which describes a reversible reversing device for auxiliary locks, which comprises a hook adapted to be moved and turned to close the door or window where the device is located, assisted by a compression spring and a lever for actuating said hook; where, in addition, the hook not only rotates, but also moves on guides belonging to an inner plate of said device.

Similarly, the German patent number DE-10063784 discloses an auxiliary lock device, wherein the hook has a plurality of notches which act as a ratchet to lock the opening of the door or window where is located , so that the displacement of an intermediate plate causes the opening of said hook through the contact between the respective notches thereof with the plate; it is a particular achievement and formed by multiple elements.

For this reason, in view of the aforementioned cases, it is necessary the appearance of a new auxiliary lock device of simple configuration, for closing and locking the door or window independently to the closure of the main lock, while by simply connecting the opening action of said device to the opening of the main lock, and being, furthermore, independent of the opening of the main lock when it is opened fraudulently by means of levers or d other similar means. In addition, this auxiliary lock is formed by a reduced number of elements with unique and new features and operation.

DESCRIPTION OF THE INVENTION

The present invention relates to an auxiliary lock device, which may be related to a main lock; and wherein said device comprises: a wraparound carcass of the device, which is housed in the edge of a door or window or the like; a latch, or trigger, configured to abut and retract when in contact with the frame of a door or window; this lock is independent of the direction of opening of the door or window; a hook, or lever, locking can adopt two positions: a first position in which the hook is located inside the wrap-around carcass, and does not come into contact with the frame of the door or window, c ' that is, does not lock the opening of the door or window; and has a second position in which the hook is introduced into a recess of the frame of the door or window by locking the opening thereof.

The lock comprises an oblong cavity which is coupled to a first projecting portion of said hook and configured as the axis of rotation of the hook; wherein the oblong cavity comprises a narrowing on one of its sides which prevents the first projecting portion from rotating when said first projecting portion is located in said narrowing, so that once the lock is moved inwardly, the first projecting portion may rotate due to not being located in said narrowing, and the hook may be introduced into the hollow of the frame by defining the second position (or locking position); in addition the hook comprises a second projecting portion located eccentrically with respect to the first projecting portion; and a cremone is located at least partially inside the wrapping carcass; where said espagnolette can be moved to, when the hook is in the second position, come into contact with said second projecting portion of the hook and push it to the first position by allowing the unlocking of the hook relative to the hollow of the frame of the door or window.

By way of clarification, we proceed to the explanation of the operating principle of the auxiliary lock device object of the invention, according to the technical characteristics described above:

The hook is located in the first position, i.e., located at least partially inside the wrapping frame, so that the first projecting portion is inserted into the narrowing of the oblong slot of the lock. , without the possibility that the hook tilts or rotates outwards, because the narrowing of the oblong cavity prevents the rotation of the first projecting portion and, consequently, the hook.

Once produced closing the door or window, it causes a movement on the lock; this displacement causes the oblong cavity to move (because of the membership of the latch), and the first projecting portion of the hook is released from the narrowing of said oblong cavity, allowing rotation of the hook and, consequently, that it turns outwards and locks the opening of the door or window; so that even if the lock is again actuated, the hook will remain fixed in the closed position without the possibility of opening the door or window.

And when it is desired to unlock the closure of said door or window, it is necessary to act on the cremone of the device object of the invention, either through another espagnolette or by means of similar elements; so that the cremone moves until it comes into contact with the second projecting portion of the hook, so as to push it to the first position by allowing the unlocking of the hook relative to the hollow of the frame of the door or window; because the hook returns to the first position and the first projecting portion can be housed again in the narrowing of the oblong cavity of the latch.

We contemplate the possibility that to ensure the locking of the hook in the second position, and that it can not be forced from the outside to proceed to the opening of the door or window, the lock device object of the invention comprises a locking cylinder coupled to a groove of the wrapping carcass, so as to be independent of the movement of the hook or the espagnolette; wherein said locking cylinder can come into contact with: the hook when it is in the second position, preventing the rotation of said hook to the first position, because preferably the hook has a curved shingles as a depression close of the head of said hook, so that the locking cylinder is coupled to said curved zone and even if a force is exerted in the direction of opening of the hook, the locking cylinder prevents the hook can withdraw to the inside of the enveloping carcass; and likewise, the locking cylinder can come into contact with the espagnolette when the latter moves towards the first unlocking position of the hook, eliminating the contact of the locking cylinder with the hook and, consequently, allowing the unlocking of the -this.

That is to say, the espagnolette is moved, either by means of another espagnolette or similar means, so as to move the locking cylinder and release the rotational movement of the hook, which is collected in the enveloping carcass also thanks to the movement of the cremone which pushes the hook through the contact between the espagnolette and the second projecting portion of said hook; connecting both the unlocking movement and rotation of the hook by moving only said espagnolette.

We contemplate the possibility that the hook comprises a third protruding portion, which is housed in a curvilinear groove belonging to the enveloping carcass, defining the limit positions of the first and second position of the hook; this third projecting portion makes it possible to guide the hook in its rotation, in addition to preventing it from rotating as well towards the inside of the enveloping carcass while being able to remain locked in the event of contact with elements close to the device the invention; as to the outside being able to be hit or turned an angle greater than that desired with respect to the engagement with the hollow of the frame of the window or door to close.

In addition, and with regard to forcing the closing movement of both the latch and the hook, the possibility is contemplated that: a first elastic element is coupled to the enveloping carcass, and is in contact with the hook by forcing the second position of the hook; that is, the closing position thereof; and - a second elastic element is coupled to the wrapping carcass, and is in contact with the latch by forcing the latch housing position in the first hollow of the frame of the door or window.

Finally, and with respect to the simplicity of the elements forming the auxiliary lock device object of the invention, it is contemplated the possibility that the enveloping carcass comprises two flat plates parallel to each other, and a plurality of elements of union between the two. flat plates, as spacers to accommodate, between the two flat plates, both the latch, the hook and the espagnolette.

Thus, according to the invention described, the aforementioned auxiliary lock device is an important novelty in the automatic lock devices currently used, and wherein said device allows the automatic closing of a door or window, preventing its opening from the door. outside, and guaranteeing the unlocking from a main lock through the action on the espagnolette belonging to the lock device object of the invention.

PREFERRED IMPLEMENTATION OF THE INVENTION

In view of the figures, it can be observed that one of the possible implementations of the auxiliary lock device that the invention proposes, comprises: An enveloping carcass (1) formed by two plane plates parallel to each other (1a, 1b), and a plurality of union members between the two flat plates (1a, 1b), as can be seen in Figure 2.

A latch (2) with a prismatic geometry, configured to abut against the frame of a door or window, where said frame is not shown in the figures although, preferably, it corresponds with the metal plates that extend the life of said lock (2); and wherein a second resilient member (10) is coupled to the wraparound carcass (1), and is in contact with the latch (2) forcing the latch housing position (2) into the first depression of the frame the door or window.

A locking hook (3) having a plane geometry and formed by a base and a beveled attacking head, wherein said hook (3) can adopt two positions:

A first position in which the hook (3) is located inside the wrap-around carcass (1) and does not come into contact with the frame of the door or window, although part of the head of attack of the hook (3) can remain outside the wrapping carcass (1) if it does not affect the correct closing of the door or window; and a second position in which the hook (3) comes into contact with a hollow of the frame of the door or window, so that it locks the opening thereof, where said hollow is not shown in the figures but it corresponds with the geometry of the attack head of the hook (3).

In addition, and in view of Figures 1 and 3, it is observed that the latch (2) comprises an oblong cavity (4) which is coupled to a first projecting portion (3a) of said hook (3) and configured as the axis of rotation of the hook (3), said first projecting portion being located near the base of the hook (3), and comprising a circular geometry with two straight chamfers, so as to have four sides, two curved and two rights, identical in pairs, as can be seen in Figures 1 and 3; wherein furthermore, the oblong cavity (4) comprises a narrowing (4a) in one of its lateral sides which prevents the first projecting portion (3a) from being rotatable when said first projecting portion (3a) is located in the narrowing ( 4a), because said narrowing (4a) reproduces the outer geometry of the first projecting portion (3a), including the chamfers; and as the latch (2) moves, the first protruding portion (3a) moves relative to the constriction (4a) and, at that time, the oblong cavity (4) comprises a similar width or slightly greater than the curved sides of the first projecting potion (4a), it is then that the first projecting portion (3a) is rotatable due to not being located in the narrowing (3a), and consequently, the hook (3a). ) can be introduced into the hollow of the frame by turning integrally with the first projecting portion (3a); where the tendency of the hook (3) to turn towards the locking of the door or window is forced by a first elastic element (9), which is coupled to the enveloping carcass (1), and is in contact with the hook (3). ).

In addition, and to allow the opening and unlocking of the door or window, it is observed in Figures 1 and 2, the hook (3) comprises a second projecting portion (3b) located eccentrically relative to the first portion protruding (3a); so that a cremone (5), which is located at least partially inside the wrapping frame (1), can be moved to, when the hook (3) is in the second position (this is that is, the locking position), come into contact with said second projecting portion (3b) of the hook (3) and push it towards the first position, allowing the hook (3) to be unlatched relative to the hollow of the frame of the door or window; this is due to the fact that the second projecting portion (3b) is integral with the hook (3) and is close to the base of said hook (3), and being located eccentrically with respect to the first projecting portion (3a) ( rotation axis of the hook (3)), there is a moment of forces which gives rise to the rotation of the hook towards the inside of the enveloping carcass (1), by unlocking the opening of the door or window by not moving that said espagnolette (5).

Compared to the action on the espagnolette (5) to allow the unlocking, in a preferred implementation the espagnolette (5) moves through the movement of a secondary espagnolette (not shown in the figures) and connected directly to a main lock; by being able to contemplate the fact that in the same door or window, is present a main lock and one or more auxiliary lock devices located higher or lower with respect to the main lock.

It is also possible that both the auxiliary device and the auxiliary are housed in the same enveloping system by configuring in itself a new lock system.

To lock the opening of the hook (3), once engaged in the hollow of the door or window, it is observed in Figures 1 and 2 the existence of a locking cylinder (6) coupled to a groove (7). of the wrap-around carcass (1), wherein said locking cylinder (6) can come into contact with: the hook (3) when it is in the second position, preventing rotation of said hook (3) towards the first position, because the hook (3) has on its head a depression not aligned with the axis of rotation of the hook (3), thus making it more difficult to turn the hook (3) to its first position if a force is exerted in the direction of opening from the leading head of said hook (3); and it can also come into contact with the espagnolette (5) when it is moved to the first unlocking position of the hook (3), by eliminating the contact of the locking cylinder (6) with the hook (3) and allowing the unlocking thereof because its rotation is not prevented by said locking cylinder (6).

When limiting the rotational movement of the hook (3), it can be seen in FIG. 2 that the hook (3) comprises a third projecting portion (3c) with a cylindrical geometry, which is housed in a curvilinear groove (8) belonging to the enveloping carcass (1), defining the limit positions of the first and second positions of the hook (3).

Finally, it can be seen in Figures 1 and 2 that the espagnolette (5) comprises a second oblong geometry in a vertical position and in correspondence with the axis of rotation of the hook (3), so as to guide the espagnolette (3) to moving it to lock or unlock the hook (3).

In view of this description and this set of figures, one skilled in the art can understand that the implementations of the invention that have been described can be combined in many ways in the subject of the invention. The invention has been described according to some preferred implementations thereof, but it will be apparent to those skilled in the art that multiple variations may be introduced into said preferred embodiments without exceeding the scope of the invention. claimed.
