Description

SECURITY DEVICE FOR CLOSING TWO SWINGING ELEMENTS, DOORS AND DOORS THAT INCLUDE SAID DEVICE

DESCRIPTION

The present invention refers to systems for closing doors and windows, and more specifically to security measures in them to prevent their unauthorized opening by intruders. Still more specifically, the present invention refers to a safety device for closing two swinging elements, a door opener and a door comprising said device.

A lock joins two swinging elements together. Swing elements or door elements can be, for example, sheets or canvas of door or window, door or window frames, among others.

The modern locks have their origin in the horizontal wooden pin that, coupled to the back of the door, was made to slide by a rudimentary guide to fit then in a hole that was practiced in the jamb or frame. To provide greater security to the lock, with the passage of time the mechanism evolved into metal-fabricated components, until reaching the traditional bolt locks. The introduction of the retractable latch in the modern lock was a substantial advance thanks to the convenience of pushing the door and let it close autonomously thanks to the inclined surface on the latch, in front of all its predecessors that force to move a pin manually after crossing it to keep the door locked. This important advance in the comfort of the user meant, however, a vulnerability in the doors that until now has been used by intruders to access unauthorized premises, with great ease, at low cost and without leaving any trace by not forcing the entrance. It suffices to have a card or flexible sheet that is inserted between the separation of the leaf of the door and the frame so that when it would slide vertically or horizontally, this contact with the inclined area of the latch and making a push movement with the blade, move the latch causing it to retract and the door to open. To deal with this problem, the locksmiths have devised multiple solutions consisting mostly of interposition elements that try to prevent access to the latch from the outside. These elements are additional accessories that protrude, installed on the outside of the lock or frame and that try to prevent the sheet from reaching the handle, interposing. An example of said device is the accessory that is sold under the name Magic Key by the company Factoría de Ideas Prácticas para el Hogar, S.L.

These accessories, in addition to not being totally reliable since most of them can be avoided, have brought with them inconveniences since they are elements that stand out from the frame and can involve a considerable change in the original installation or they produce accidents due to the ease with which the they get hooked with the clothes of the users or in other elements. In the same way, this drawback also causes the deterioration of the system with the passage of time due to snags. On the other hand, systems have been developed in the locks that block the latch automatically, as for example the one shown in document ES1047686U. These systems are quite effective, although more expensive and complex to install. For example, those that work with an extra trigger, fail if the distance between the frame and the lock is very large, having more distance produces that the magazine is not pressed enough and does not stop blocking the latch. On the other hand, if a door with this system is installed correctly in summer but with the operation to the limit, when winter arrives and the door collapses, it may be the case that it does not block the latch. It is an object of the present invention to provide security means for all types of doors and windows that do not have the drawbacks described above.

More particularly, the present invention discloses a safety device for closing two swinging elements, the device comprising an interposition means designed to block access to the latch through the slot between the swinging elements to be closed. The interposition means has at least one inactive position in which it is collected and an active position, in which it is preferably deployed. The device also comprises an activation mechanism for activating the interposition means at the moment of closing the door. The present invention discloses the use of an retractable interposer element or means and which is activated only in response to the door or window closure. This presents a series of advantages that can not be appreciated in the prior art. The system is simple and does not deteriorate over time. On the other hand, by being mobile, and deployable, the system performs a force that prevents unauthorized opening. Additionally, it can be designed so that in the inactive position it does not protrude from the lock, door opener or swing element, solving the problem of the interposition housings of known type. The solution of the invention is especially advantageous in the field of so-called door openers.

An object of the present invention is to prevent unauthorized access by preventing by blocking the introduction of an element, for example flat and flexible, until contacting the latch. For this, preferably, the access must be prevented not only directly to the height at which the bolt is located, but also from points located superiorly and inferiorly, that is to say, introducing the element at a point away from the latch and then sliding it along from the slot until the handle is reached.

It is therefore a matter of avoiding an attack on the latch not only frontally, but also superiorly or inferiorly. For this, preferably, the interposition means of the present invention must have larger dimensions than the latch, and, more preferably, that the orifice intended to give access to the space or reception box of the latch.

The interposition means may, for example, present a screen or casing shape.

The device can be designed so that any event related to the closing of the door unfolds the interposition means. For example, closed sensors can be used, or use the latch entrance in their space during the closure, or taking advantage of their push to generate the deployment movement or it may be used to make a metallic contact of the latch with another element to generate the deployment signal.

The form of deployment of the interposition means (or casing) can be any and present different motion kinematics between the inactive position and the active position. However, according to the present invention, it is particularly advantageous for the interposition means to be rotatably or pivotably connected to the activation mechanism, in such a way that the interposition means passes from the inactive position to the active position by rotation. This makes it possible to ensure that the device does not protrude in the inactive position, and also facilitates the activation, since the device can be arranged as a rocker around its axis of rotation, in such a way that the entrance of the latch at one end causes the output of the device. means of interposition by the other.

The terms "turn" and "rotationally" in the present application comprise, in addition to turns in a strict sense, compound movements of translation and displacement.

Preferably, the interposition means, in inactive position, exceeds the limits or laterals of the space or reception box of the latch. This gives additional protection when the interposition means is activated, especially when it is activated by rotation, since if the interposition medium presents dimensions equal to or lower than those of the box or space and, in addition, does not exceed the limits of the space or latch reception box along the development plane of the interposition means when it is placed in inactive position, then, the interposition means, in active position, that is, raised, would leave a free space through which it would be possible to access for force the lock. However, if the end of the interposition means that is deployed is initially located beyond, at least some, limits or sides of the box, covering them, said available space is limited and even nullified. The interposing means can pass different sides of the space or box to avoid attacks from any direction, it being preferable that one end of the free interposition means parallel to the axis of rotation and that is deployed upon activation of the interposition means exceeds or covers a limit or side of said box or space. Preferably, the activation means comprises a drive arm that is connected to the interposition means through a common rotation axis, in such a way that the actuation of the arm causes activation by rotation of the interposition means. This arm may occupy part or all of the latch reception area. In accordance with the present invention, it is advantageous that the arm and / or the interposition means are flexible. In particular, the flexibility of the arm and / or interposition means facilitates, by its non-permanent deformation, the full entry of the latch even when the interposing means abuts the opposite door leaf before the latch reaches the end of its travel. To favor this effect, preferably, the device comprises a bent rod with rotational capacity with respect to said common axis of rotation and having at least a first section in contact with the interposition means and a second section in contact with the arm. The rod, or strip, can carry out several functions, among them:

Favor the flexing of the arm indicated above, and / or

Transmit movement of the arm to the interposition means, and / or

- Exercise as an elastic medium whose force tends to carry the means of interposition to its inactive position.

Alternatively, the interposition means may have, in an integrated manner, two protrusions (for example, axis) which are placed in corresponding rotary connection areas, the interconnection means pivoting on said rotary connection areas. The device can have several rotation grooves, parallel to each other to receive said axes, in order to adjust the position of the interposition means by choosing the slots in which the axes are placed.

The distance between the swing elements to close, in closed position, is variable depending on the conditioning factors of the installation. In the case that the distance is very small, there is a danger, in some embodiments, that the interposition means will not be lifted or deployed sufficiently. In order to minimize this danger, the present invention provides that the device may have an interposition means or auxiliary screen in contact with the arm. Said auxiliary interposition means may have smaller dimensions than the interposition means or main screen.

Preferably, the interposition means has a plurality of grooves on its outer face, which are preferably oblique with respect to the plane of said outer face and which penetrate the face away from the axis of rotation. These slots are an additional means of protection, since they act as hooks for inserted cards in order to save the interposition means and reach the latch. Even more preferably, the profile of the interposition means will be shaped such that it generates a ramp in the direction of said grooves. The purpose of this feature is to direct the card towards the slots. For example, the interposition means may have a dovetail-shaped end. One of the advantages of the present invention is that it is applicable to all types of locks. It is also applicable to existing locks. For this purpose, the device may comprise a plate (or "frame") for a recessed connection in a hinged element (for example, a frame or door leaf), the plate having a hole for receiving a latch. Preferably, the interposition means does not protrude from said plate. Preferably, said arm is located in said hole for receiving a latch. Preferably, the device has lugs that are inserted into corresponding holes in the plate in order to reinforce the mechanical stability of the entire mechanism.

Preferably, the interposition means has a through hole to promote access to elements of the box when the interposition means is in the inactive position.

The present invention also discloses door openers that have the device object of the present invention. Preferably, it comprises an outer surface of alignment with the edge of the a swing element, and the device, in inactive position, is housed in the door opener, without protruding from the outer surface. More preferably, the activation mechanism is located in a receiving space of a latch of the lock, in such a way that the entrance of the latch in said space causes the activation of the device. Even more preferably, the door opener is an electromechanical, electromagnetic, motorized, pneumatic or hydraulic opening element.

The present invention also discloses doors and / or windows comprising a device or a door opener according to the present invention. Preferably, said door opener will be embedded or superimposed on the frame of the door and / or window.

The present invention is of special application to the door openers, although the invention can be applied to any type of lock, such as a simple latch lock manually operated and / or by key. In short, the present invention happens to be a system that when the door is closed leaves the frame or the door to protect the latch and hides totally or partially when the door is open. The present invention has the advantage that it can be an independent system or integrated within another as, for example, in a door opener. The present invention can be adjustable to adapt to any installation and latch. The present invention, in addition, allows to provide additional protection systems such as, for example, auxiliary screens, ramps for deflecting the cards, hooks, etc. that increase the difficulty to open the system in any direction from which to try to force. In addition, a series of stops can be included that prevent excessive rotation of the interposition element, thus ensuring its integrity against undue use. Finally, the present invention also has as an advantage its adaptability to the distance between the door and the frame.

As can be deduced, the present invention also discloses a lock reinforcement, comprising a plate with a hole for receiving a latch and holes for receiving fastening elements to a hinged element, said reinforcement comprising a recess of the thickness of the plate in contact with at least one side of said hole, on the outside face of the frame. Preferably, said reinforcement further comprises holes for receiving lugs. More preferably, the recess has a length greater than that of the lateral one. Even more preferably, said recess is in the form of a dovetail. For better understanding, drawings of embodiments of the present invention are attached as explanatory but not limiting examples.

In the figures, equal or equivalent elements have been identified with identical numerals. Figures 1 and 2 schematically show a first embodiment object of the present invention. The elements have been represented in a very schematic way and shapes, distances and proportions have not been conserved. Also, in the closing position it has been omitted that the door leaf -100- rotates around its hinge and therefore moves according to a circular path.

In Figure 1 two door leaves -100-, -101-, (the second door leaf -101- could also be a door frame) are observed. In the first door leaf -100- a handle -50- has been represented. In the second door leaf -101- an interposition means or shell -1- is shown which, in the inactive position, remains inside the door leaf -101- and does not protrude with respect to the outer surface of the edge of the second one. door leaf -101 -. In Figure 2, the door has been closed and the interposing means -1- has been unfolded and has passed to the active position.

The means of interposition -1 - has the function of blocking unwanted access, in an attempt to force the opening of the door. Therefore, the interposition means object of the present invention is deployed until, preferably, it makes contact with the first door leaf -100-. In the example shown, the deployment is carried out by translation, specifically by a linear displacement. The translation can be carried out by an elastic means or by any other means (mechanical thrust, electric motor, hydraulic thrust, pneumatic, etc.). The deployment path can be any. The event that causes activation of the interposition means -1 - must be related to the closing of the door. More specifically, a sensor for closing the door, for movement of the door leaf -100-, the entrance of the latch -50- in the space for receiving it in the second door panel -101-, or any other element can activate it. .

It is observed that the interposition means is preferably deployed until contacting the outer surface of the hinged element (door leaf -100-) without entering any hole. In preferred embodiments, there is no reception recess of the interposition means -1- in the leaf element -100- that receives the interposition means -1- in the deployed (active) position.

In the figures it can be seen that the system is not affected by the free space remaining between the door leaves -100-101, since the interposition means -1- can be deployed until it makes contact with the first door leaf. -100- door. Therefore, the system is equally effective for a wide range of distances between door leaves -100-, -101-, or between door and door, remaining during door installation. Another advantage that can be observed is that the interposition means does not protrude from the edge of the second door leaf -101-.

Preferably, the interposition means -1- has a dimension greater than that of the latch -50-. It is even more advantageous if the interposition means -1- has larger dimensions than the hole into which the handle -50- is inserted. In particular, in the example, it is convenient that in the direction perpendicular to that shown in FIGS. 1 and 2 (ie, a direction parallel to the junction between the swinging elements 100 and -101), the interposition means -1 - is larger than the handle and the hole for it, thus offering greater protection against unauthorized access. Figures 3 to 10 show an example of embodiment of the object of the present invention. In the different figures, identical or similar elements have been identified with identical numerals. In particular, FIGS. 3 to 10 show a electric lock release 2, which has a safety device according to the present invention. This type of door opener is usually used in automatic door openers and access controls, and presents the security problems present in the locks latches, since the doors remain closed only by the action of a latch.

In the case shown, the zone comprising the lower zone of the rod -12- up to the connection piece -1 1 1 - which, in this case, acts as a spring.

The example of figure 3 is based on a built-in type door opener -2-. It contains what is called a latch, that is, a space -28- or a box for receiving a latch and, in this concrete example, elements for its normal opening. The opening function is carried out by means of a release of the internal mechanism that releases the rotation of the latch -29-. The user, when pushing the door, pushes the latch of the opener -29- through the latch of the lock -50-, turning the latch until the latch of the lock is released, at which time the door remains open.

The example shown in FIGS. 3 to 10 can be made from a lock release of known type, by replacing the connection plate -21-, to which the interposition means -1- is connected. The connection plate -21- has a recess for receiving the interposition means -1 - in such a way that it does not protrude. This can be done in a simple manner, since in most of the door openers, the lock-release mechanism is connected to the plate -21- by means of screws -22-. The plate 21 is intended to be approximately flush with the edge of the door leaf or frame in which it is installed, and therefore, without protruding from it. Therefore, the plate 21 comprises an outer surface of alignment with the edge of a leaf element.

As shown in the figures, the interposition means -1 - is connected in a rotary manner (in this case by rotary connection areas -15-, which in this case have the shape of projections and whose function is to reduce friction and favor the turn). In the inactive position, it remains inside the frame and does not protrude from the door opener (nor, therefore, from the edge in which it is installed), while it passes to the active position by means of rotation.

In the rest position shown in figure 3, it can be seen how the interposition means -1 - exceeds the limits of the space -28- or latch reception box in the development plane of the interposition means. In particular, in the case shown, the interposition means extends beyond the side of the latch box by the end 13 which unfolds during the rotation of the interposition means. In this case, said part that exceeds the limits of the box is housed in a recess -213- in the plate -21- to prevent, in the inactive position, the interposition means -1- from protruding from the connection plate -21- . However, the interposition means, despite exceeding the limits of the box on its side, does not protrude from the plate perpendicular to it. For example, an elastic means can be provided to ensure the return of the interposition means to the inactive position from the active position. In the example shown, this can be achieved by the action of the rod 12, magnets, spring or strap. To this end, in certain cases, operating elements already known in door openers such as the bolt of the automatic function or the activation element of the microswitch could also be used.

In the example, the interposition means -1 - is activated by the latch. For this, the device comprises an arm -19-. The arm is located in the hole for reception of the latch defined, for example, by the plate -21-. The arm is connected to the interposition means -1 - on the side opposite to the axis of rotation of the interposition means -1 -, in such a way that the entrance of a latch pushes the arm -19- into the latch, causing the exit from the means of interposition. In the concrete example shown in figures 3 to 10 and 12, the arm -19- is flexible, which allows it to continue to flex and allow the entry of the latch even when the interposition means has contacted the door leaf and, for therefore, it does not rotate anymore. To favor said flexing, the rod 12 is bent and has a section in contact with the arm -19-. Said section of the rod -12- in contact with the arm -19- is separated from the axis of rotation to favor the lever arm and the flexing. Likewise, the rod -12- is in contact with the interposition means -1 - on a face opposite to the contact with the arm -19- (with respect to the axis of rotation), in such a way that the rod can also act as Transmitter of the movement of the arm -19- to the interposition medium -1-.

The interposition means -1 - has slots -13-, -14- (see figure 6) and / or steps whose purpose is to act as hooks to deflect and block attempts to overcome the interposition means above or below. by cards with special shapes, for example, L-shaped. Indeed, if the card contacts any of the slots -13-, -14-, when the interposition means is deployed, they trap and block the card. For this, the grooves of a possible example are oblique with respect to the plane of the outer face of the interposition means -1 - in which they are placed and penetrate the face / interposition means away from the axis of rotation. Preferably, said grooves will be located in the vicinity of the axis of rotation, although they can be placed anywhere. The action of the grooves -13-, -14- is complemented by the free end -1 13- in the form of a dovetail or triangular. Said zones -18- form ramps in the perimeter of the interposition means that direct a card introduced in the slot towards the ramps -13-, -14-. Likewise, the fact that the free end 13 has, in the direction of the axis of rotation of the interposition means -1-, a length greater than that of the latch reception area -50- also makes access difficult authorized by cards or rods to the device to violate the safety of it.

In the example shown, the interposition means has two parts, also comprising an auxiliary screen -1 1 -. This arrangement has the purpose of favoring the adaptation of the device at very small distances between door leaves or between slot and door leaf. In this case, it must be avoided that the interposition means prevent the latch from penetrating completely.

This construction can be seen in figures 4, 5 and 8 to 10. In said figures for reasons of clarity have been removed different elements shown. In all the figures, the greatest part of the door opener, except for the opening mechanism -29- (said mechanism is not necessary to carry out the invention, which may be applicable to other types of closing devices). In figures 4 and 5 the shell has also been removed from the interposition means -1 -, which can nevertheless be seen in figures 8 to 10.

The auxiliary screen -1 1 - together with the arm -19- and the connecting piece -1 1 1 - are preferably elements of flexible material which are connected to the interposition means -1 -. Arm -19- and auxiliary screen -1 1 - can be joined in such a way that the flexion of the arm -19- always produces a lifting of the auxiliary screen which, in case the interposition means -1- does not lift, results independent of the means of interposition. In this case, the auxiliary screen -1 1 - can perform interposition media functions. The connecting piece -1 1 1 - of the example is integrated with the arm -19- although it can work separately, and its function is to act as a spring that tends to hide the device when the door is opened. Both the arm -19- and the connection piece -1 1 1 - can be connected to the interposition means -1 -. Said connection is made, for example, by holes -1-12- in the arm -19- (see figure 5) and projections or lugs -113'- placed in the lower face of the interposition means -1- (see figures 8). to 10).

Figures 8 to 10 show the process of closing and deploying the security mechanism. Figure 8 shows the moment in which, when closing the door, the handle -50- contacts the arm -19-. The interposition means does not protrude from the outer surface -21-, being integrated inside the plate. In figure 9 the latch has penetrated more, pressing and pushing the arm -19- inwards and causing the interposition means -1- to come out, since the assembly pivots around its axis of rotation (which coincides with the main axis or rotation of the rod -12-). For this to occur, it is advantageous that the elastic force exerted by the arm -19- be less than that of the spring of the latch. Figure 10 shows how the latch has been inserted until the end, but in this case the arm has flexed without turning the main part of the interposition means further. It is therefore advantageous that the arm is soft enough to allow this effect without overcoming the spring force of the latch (not shown). As it is observed, the interposition means -1 - has not moved, but it is observed that the auxiliary screen -1 1 - has been deployed, practically touching with the door leaf -100-.

The interposer can have different slots for placing it in different positions with respect to the axis of rotation. This allows to regulate the position of the interposition means -1 - or shell. This can be useful if the latch is wide or it is necessary to adjust the flap of the electric lock to adjust the closing of the door.

In Figures 8 to 10, the interposition element -1 - has not been shown flexible enough to deform. However, this can be a desired effect in certain cases, as the deformation would increase the contact surface between the interposition means -1 - and the edge of the first door leaf -100-.

In the present specification, the flexible term or flexible material should be understood as being capable of bending / deforming under normal use stresses, returning to its original shape when left to apply the external force in question. In general, plastic and / or synthetic materials can be used as elastic materials, although metal can also be used, as long as their dimensioning allows obtaining the aforementioned effect. Figure 1 1 shows three possible embodiments -500-, -600-, -700- of the interposition means -1-. Elements equal or equivalent to those previously shown have been identified with identical numerals and will not be explained in detail. In the embodiment -500-, there is a central square area -19- of the rod -12-. In this zone -19-, a straight strip enters that when turning, rotates on the edge of the slot making rod -12-. In this case, the articulated connection area -15- of the interposition means is an element for reducing the friction in the rotation that occurs at the ends of the equivalent rod -12-.

In the embodiment -600-, the arm -19- is thick and, therefore, is not flexible. The articulated connection zone -15- are projections that can be integrated or form part of the interposition element -1 - that do not have an orifice for the rod or strip and that can act as the ends of the rod -12- of other embodiments, being able to use without it.

The embodiment -700- is intended for the solid, hard and flexible (for example metallic) realization of the interposition means. This embodiment aims to combine the functions of interposition means -1 - and arm -19- in a single piece. For this, the interposing means is Z-shaped. The embodiment lacks anti-card slots but is capable of being implemented. It can also be used without a rod, for example by using another elastic return element (for example, the bolt of the automatic function of a door opener). In the three embodiments -500-, -600-7, -700- the interposition element is a single piece, the auxiliary screen device lacking.

Figures 12 to 16 show a further embodiment of a device according to the present invention. Equal elements, similar or equivalent to those of the embodiments shown above have been identified with identical numerals.

As seen in the figures, the interposition means -1 - is of the rotating type. The free end 13 of the interposition means 1 passes one side of the space 28 which is parallel to the axis of rotation of the interposition means. In addition, the length of said free end 13 is greater than the length of said side of the box. Likewise, the interposition means has an orifice -1-10- which allows access to the bottom of the box, in order to be able to access terminals for adjusting or disassembling the assembly without the need to actuate or disassemble the interposition means.

Additionally, the device has locking lugs 51 which are inserted into corresponding holes 215 of the plate 21. The lugs -51- rigidify the system.

Figure 14 shows the plate -21- with the hole -223- corresponding to the box, the recess -213- to receive the free end of the interposition means (protruding from the box) and the holes corresponding -215- for the lugs. The holes -216- are also observed for screwing the edge of the hinged element (not shown in the figures).

In this example, the lugs -51- shown are integrated in a plate -5- (see figure 15) which, together with another plate -6-, is interposed between the built-in door opener -2- and the plate -21-. The plate -5- has, in addition to the lugs, an empty area -523- corresponding to the hole in the space -28- of the door opener -2-, holes -59- corresponding with the holes -216- for screws of the plate -21 -. It also has several slots -559- to receive the axis of rotation of the interposition means -1-. The other plate -6- prevents the interposition element -1- from leaving its housing in the plate -5- during operation and during the adjustment process. It has some reinforcements -61- that ensure an optimal distance between the door lock mechanism -2- and the plate -21-, protect the means -1 1 1 - and ensure a correct placement of the other plate -5-. On the other hand, other regulation systems are possible to adjust the position of the interposition element, such as, for example, the displacement of the assembly formed by the plates -5- and -6- with respect to the screws -22- making the holes elongated -59-. In this case, the adjustment can be ensured by means of serrations located on the rear part of the plate -5- and on the contact surface with the door opener -2- or the plate -21- (not shown).

In this example, the rod has been eliminated and integrated into the piece that forms the interposition medium, becoming solid.
