Security device for closing two hinged elements, the device comprising an interposition means intended to block access to the latch through a channel between the hinged elements to be closed, wherein the interposition means has at least an inactive position in which said means is retracted and an active position, and wherein the device also comprises an actuation mechanism for moving the interposition means from the passive position to the active position when the hinged elements are closed.
The present invention relates to door and window closing systems, and more specifically to security means in said systems for preventing the unauthorised opening thereof by intruders. Even more specifically, the present invention relates to a security device for closing two hinged elements, to a door opener and to a door which comprises said device.
A lock connects two hinged elements to each other. Hinged element or door element may include, for example, door or window leaves or panels, or door or window frames, among others.
Modern locks have their origin in the horizontal wooden bolt which, attached to the back portion of the door, was slid through a rudimentary guide in order then to fit into a hole which was made in the jamb or frame. To give the lock greater security, with the passage of time the mechanism evolved into components made of metal, resulting ultimately in the conventional barrel bolts. The introduction of the retractable latch in the modern lock was a substantial advance owing to the convenience of pushing the door and allowing said door to close autonomously owing to the sloping surface of the latch, compared to its precursors where a bolt had to be moved manually to keep said door closed after being passed through. However, this important advance in user convenience gave the doors a vulnerability which up to the present time has been taken advantage of by intruders to gain unauthorised access to spaces very easily, at little cost and without leaving any trace as there was no forced entry. All that is needed is a flexible card or sheet which is inserted in the gap between the door leaf and the frame such that when said card or sheet is slid vertically or horizontally, said card or sheet makes contact with the sloping region of the latch and by making a pushing movement succeeds in moving the latch, causing said latch to retract and the door to open.
To confront this problem, locksmiths have devised many solutions, mostly consisting of interposed components which attempt to prevent access to the latch from the outside. Said components are additional accessories which project, installed on the outside of the lock or the frame and which attempt to prevent the sheet from reaching the latch, by being interposed.
An example of said device is the accessory commercialised under the name Magic Key by the company Factoría de Ideas Prácticas para el Hogar, S.L.
These accessories, as well as not being totally reliable, because most can be circumvented, have drawbacks as they are components which project from the frame and may result in a considerable change to the original installation or alternatively can easily cause accidents as said components may become caught in the clothing of users, or in other components. Similarly, this drawback also causes damage to the system over time owing to items becoming caught.
In addition, lock systems have been developed which automatically immobilise the latch, as shown in document ES1047686U, for example. Said systems are reasonably effective, although more costly and complex to install. For example, those that function with an extra trigger fail if the distance between the frame and the lock is very great, as the greater distance means that the loader is not under sufficient pressure and does not ultimately immobilise the latch. Furthermore, if a door comprising this system is properly installed in the summer but operating at its limit, when winter arrives and the door contracts, it may not immobilise the latch.
An object of the present invention is to disclose security means for all types of doors and windows which do not have the drawbacks described above.
More particularly, the present invention discloses a security device for closing two hinged elements, said device comprising interposition means intended to block access to the latch through a channel between the hinged elements to be closed. The interposition means has at least an inactive position in which said means is retracted and an active position in which said means is preferably deployed. The device also comprises an actuation mechanism for actuating the interposition means when the door is closed.
The present invention discloses for the first time the use of a retractable interposed element or means which is actuated only in response to the closing of the door or window. This has a series of advantages which cannot be found in the prior art. The system is simple and does not deteriorate over time. Furthermore, as said system is moveable and deployable, it produces a force which prevents unauthorised opening. In addition, said system can be designed so that in the inactive position it does not project beyond the lock, door opener or hinged element, thus overcoming the problem of known interposed structures.
The interposition means may take the form of a screen or casing, for example.
The device can be designed so that any event related to the closing of the door deploys the interposition means. For example, closure sensors or the entry of the latch into its space during closing could be used, taking full advantage of the force thereof to produce the deployment movement or alternatively the metallic contact of the latch with another component could be used to produce the deployment signal.
The interposition means (or casing) could be deployed in any way and present different movement 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 connected to the actuation mechanism in such a way that the interposition means passes from the inactive position to the active position by means of rotation. This makes it possible to ensure that the device does not project in the inactive position and also facilitates actuation, as the device can be arranged so as to rock about its axis of rotation, in such a way that the entry of the latch at one end causes the interposition means to emerge at the other.
The terms 'rotation' and 'rotatably' in the present application cover, in addition to rotations in the strict sense, movements made up of translation and displacement.
Accordingly, preferably, the actuation means comprises an arm which can be actuated and is connected to the interposition means through a common axis of rotation, in such a way that actuation of the arm causes the actuation by rotation of the interposition means.
According to the present invention, it is advantageous for the arm and/or the interposition means to be flexible. In particular, by means of its non-permanent deformation, the flexibility of the arm facilitates the full entry of the latch even when the interposition means abuts the opposite door leaf before the latch reaches the end of its travel.
To assist this effect, the device preferably comprises a bent rod having the ability to rotate relative to said common axis of rotation and which has at least a first length in contact with the interposition means and a second length in contact with the arm.
The rod, or strip, may perform various functions, including:
- Helping the above-mentioned arm to flex, and/or
- Transmitting movement from the arm to the interposition means, and/or
- Acting as a resilient means, the force of which tends to take the interposition means to the inactive position thereof.
In the closed position, the distance between the hinged elements to be closed varies depending on the installation constraints. If the distance is very small, there is a risk, in some embodiments, that the interposition means may not rise or deploy sufficiently. To minimise this risk, the present invention provides for the device to be able to have an auxiliary interposition means or screen in contact with the arm but which is not in contact with said rod. Said auxiliary interposition means may have smaller dimensions than the main interposition means or screen.
Preferably, the interposition means has a plurality of grooves on its outer face, which are oblique relative to the plane of said outer face and which are cut into the face in a direction moving away from the axis of rotation. Said grooves are an additional means of protection, as they act as hooks for cards inserted in order to get round the interposition means and reach the latch. Even more preferably, the profile of the interposition means is shaped so as to form a ramp in the direction of said grooves. The purpose of this feature is to direct the card towards the ramps. For example, one end of the interposition means may be flared.
One of the advantages of the present invention is that it can be applied to any type of lock. It can also be applied to existing locks. The device may accordingly comprise a connection plate embedded in a hinged element (for example a frame or door leaf), the plate having an aperture for receiving a latch. Preferably, the interposition means does not project beyond said plate. Preferably, said arm is located in said aperture for receiving a latch.
The present invention also relates to door openers that comprise the device according to the present invention. Preferably, it comprises an outer surface for alignment with the cant of a hinged element, and in the inactive position is housed in the lock and does not project beyond the outer surface. More preferably, the actuation mechanism is located in a space for receiving a latch of the lock, such that the entry of the latch in said space produces the actuation of the device. Even more preferably, the door opener is an electromechanical, electromagnetic, motorised, pneumatic or hydraulic opening component.
The present invention also discloses doors and/or windows that comprise a device or a door opener according to the present invention. Preferably, said door opener is embedded in or placed on the frame of the door and/or window.
The present invention applies in particular to entry phone systems, although the invention may be applied to any type of lock, such as a simple latched lock actuated manually and/or with a key.
In conclusion, the present invention is considered to be a system that emerges from the frame or door when the door is closed in order to protect the latch, and is fully or partly withdrawn when the door is open. An advantage of the present invention is that it may be an independent system or it may be incorporated in another system such as a door opener, for example. The present invention can be adjusted so as to adapt to any installation or latch. Moreover, the present invention allows the provision of additional protection systems such as ramps, for example, for deflecting cards, hooks, etc., which make it more difficult to break into the system. Finally, the present invention also has the advantage of being adaptable to the distance between the door and the frame.
To aid understanding, explanatory yet non-limiting drawings are included of embodiments of the present invention.
- Fig. 1 is a diagrammatic view of a door leaf and a frame, comprising a latch and an interposition means according to the present invention, in the open position with the interposition means in the inactive position.
- Fig. 2 shows diagrammatically the arrangement from Fig. 1 in the closed position and with the interposition means in the active position.
- Fig. 3 is a perspective view of an embodiment of the present invention, showing an electric door opener which has a security device according to the present invention.
- Fig. 4 is a view from above corresponding to the example from Fig. 3, in which for informational purposes some of the components of the security device and a portion of the door opener have been removed.
- Fig. 5 is a perspective view of the components that can be seen in Fig. 4.
- Fig. 6 is a perspective view from a different point of view of the example from Fig. 4, with the security device in the inactive position.
- Fig. 7 is a perspective view which corresponds to Fig. 6, with the security device in the active position, the arrow indicating the action of the latch.
- Fig. 8 is a diagrammatic view of a cross section in a horizontal plane of the device from Fig. 3 to 7 installed in a door, the door being open.
- Fig. 9 is a diagrammatic view which corresponds to Fig. 9, at an intermediate stage of closure.
- Fig. 10 corresponds to Fig. 8 and 9, with the door completely shut, and only a very small gap between the leaves of the door (or between door and frame).
In the figures, elements that are the same or equivalent have been identified with the same reference numerals.
Fig. 1 and 2 show a first embodiment of the present invention diagrammatically. The components have been shown very schematically and shapes, distances and proportions have not been faithfully preserved. Moreover, in the closed position the rotation of the door leaf -100- about its hinge and hence its movement in a circular trajectory have been omitted.
In Fig. 1, two door leaves -100-, -101- can be seen (the second door leaf -101- could also be a door frame). A latch -50- has been shown on the first door leaf -100-. An interposition means or shield has been shown on the second door leaf -101-, which in the inactive position remains inside the door leaf -101- and does not project relative to the outer surface of the edge of the second door leaf -101-. In Fig. 2, the door has been closed and the interposition means -1- has been deployed and has moved to the active position.
The function of the interposition means -1- is to block unwanted access, in an attempt to force the door open. The interposition means according to the present invention therefore deploys until, preferably, making contact with the first door leaf -100-. In the example shown, the deployment takes place by translation. Translation may take place in a manner impelled by a resilient means or by any other means (mechanical thrust, electric motor, hydraulic or pneumatic thrust, etc.). Any type of deployment trajectory is possible. The event that causes the actuation of the interposition means -1- should be related to the closing of the door. More specifically, said means may be actuated by a sensor for the door closing, for a movement of the door leaf -100-, the entry of the latch -50- into its reception space in the second door leaf -101-, or for any other event.
The figures show that the system is not affected by the free space between the door leaves -100-, -101-, as the interposition means -1- can be deployed until contact is made with the first door leaf -100-. The system is therefore equally effective regardless of the distance remaining between door leaves -100-, -101-, or between leaf and door, during the installation of the door. Another advantage that can be seen is that the interposition means do not project beyond the edge of the second door leaf -101-. -.
Fig. 3 to 10 show a second embodiment of the present invention. In particular, they show an electric door opener -2- in Fig. 3, 6 and 7 which has a security device according to the present invention. This type of door opener -2- is normally used in entry phone systems and access controls, and does not overcome the security problems present in lock latches, as the doors are kept closed only by the action of a latch.
In the different figures, elements that are the same or similar have been identified with identical reference numerals. In the example shown, the region which comprises the lower region of the rod -12- up to the connection part -111- acts as a spring.
In the example shown in Fig. 3, a portion of an embeddable door opener -2- contains what is known as a catch, that is, a space -23- or recess for receiving a latch and, in this specific example, components for the normal opening thereof. The opening function is produced by releasing the internal mechanism which frees the rotation of the catch -29-. When pushing the door, the user pushes the catch of the door opener -29- by means of the latch of the lock -50-, causing said catch to rotate until the latch of the lock is released. At this point the door has opened.
The example shown in Fig. 3 to 10 can be produced from a door opener of a known type, by substituting 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 said interposition means does not project. This can easily be carried out, as in most door openers the door opener mechanism is connected to the plate -21- by screws -22-. The purpose of the plate -21- is to remain approximately flush with the cant of the door leaf or frame in which said plate is installed and therefore without projecting therefrom. Thus, the plate -21- comprises an outer surface for alignment with the cant of a hinged element.
As shown in the figures, the interposition means -1- is rotatably connected (in this case by means of rotating connection regions -15-, which in this case take the form of projections, of which the function is to reduce friction and encourage rotation about the rod -12-). In the inactive position, said interposition means remains inside the framework and does not project from the door opener (and hence not from the cant in which said means is installed) while moving to the active position by means of rotation.
Resilient means, for example, may 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-, spring or strip. Accordingly, in some cases it would also be possible to use known operating components in door openers such as an automatic-function pin or micro-switch actuation element.
In the example, the interposition means -1- is actuated by the latch. To do this, the device comprises an arm -19-. The arm is located in the opening for receiving the latch defined, for example, by the plate -21-. The arm is connected to the interposition means -1- on the side opposite the axis of rotation of the interposition means -1-, in such a way that the entry of a latch pushes the arm -19- towards the inside of the catch, causing the interposition means to come out. In the specific example shown in figures 3 to 10, the arm -19- is flexible, which allows said arm to continue to flex allowing the latch to enter even when the interposition means has made contact with the door leaf and, therefore, no longer rotates. To encourage said flexing, the rod -12- is bent and has a length in contact with the arm -19-. Said length of the rod -12- in contact with the arm -19- is separated from the axis of rotation to assist the lever arm and the flexion. Moreover, the rod -12- is in contact with the interposition means -1- on a face opposite that in contact with the arm -19-, so that the rod can also act as a transmitter of the movement of the arm -19- to the interposition means -1-.
The interposition means -1- has grooves -13-, -14- (see Fig. 6) and/or steps, the purpose of which is to act as hooks to deflect and block attempts to overcome the interposition means from above or below using L-shaped cards. If the card makes contact with one of the grooves -13-, -14-, when the interposition means is deployed, said grooves trap and block the card. Accordingly, the grooves in the example are oblique relative to the plane of the outer face of the interposition means -1- in which said grooves are located in and cut into the face/interposition means in a direction moving away from the axis of rotation. Preferably, said grooves are located in the vicinity of the axis of rotation, although they may be positioned anywhere.
The action of the grooves -13-, -14- is complemented by the flared or triangular free end. Said regions -18- form ramps at the perimeter of the interposition means which directs a card inserted in the groove towards the ramps -13-, -14-.
In the example shown, the interposition means has two parts, and also comprises an auxiliary screen -11-. The purpose of this arrangement is to help the device to adapt to very small distances between door leaves or between groove and door leaf. In this case, the interposition means should not prevent the latch from entering fully.
This construction can be seen in Fig. 4, 5 and 8 to 10. For reasons of clarity, some of the elements shown have been eliminated in said figures. In all the figures, most of the door opener has been eliminated, except for the opening mechanism -29- (said mechanism is not necessary for implementing the invention, which can be applied to other types of closure devices). In Fig. 4 and 5, the shield of the interposition means -1- has also been eliminated, although it can be seen in Fig. 8 to 10.
The auxiliary screen -11- together with the arm -19- and the connection part -111- are laminar components made of a flexible material which are connected in the connection region -191- (in this case, the connection region -191- also happens to be the contact region of the rod -12- with the arm -19-). The arm -19- and the auxiliary screen -11- are connected in such a way that the flexion of the arm -19- always produces a raising of the auxiliary screen which, if the interposition means -1- does not rise, occurs independently of the interposition means. In this case, the auxiliary screen -11- may perform functions of the interposition means. The connection part -111- in the example is incorporated in the arm -19- and its function is to connect the arm -19- with the parts contained therein, fix the strip and allow said strip to actuate or as a spring which tends to retract the device when the door is opened. Its function is to connect the assembly to the interposition means -1-. Said connection is produced by means of openings -112- in the connection part -111- (see Fig. 5) and projections or lugs -113- positioned on the lower face of the interposition means -1- (see Fig. 8 to 10).
Fig. 8 to 10 show the process of closing and deploying the security mechanism. Fig. 8 shows the moment when, on closing the door, the latch -50- makes contact with the arm -19-. The interposition means does not project from the outer surface -21-, and remains incorporated within the framework. In Fig. 9, the latch has entered further, pressing and pushing the arm -19- inwards and causing the interposition means -1- to come out, because the assembly pivots about its axis of rotation (which coincides with the main axis or axis of rotation of the rod -12-). For this to occur, it is advantageous if the resilient force applied by the arm -19- is less than that of the latch spring. Fig. 10 shows that the latch has been inserted to the end, but in this case the arm has flexed without causing the main portion of the interposition means to rotate. It is therefore advantageous for the arm to be sufficiently yielding to allow this effect without overcoming the force of the latch spring (not shown). As can be seen, the interposition means -1- has not moved, but it can be seen that the auxiliary screen -11- has been deployed, until it practically touches the door leaf -100-.
The interposition means may have various grooves for placing same in different positions relative to the axis of rotation. This allows the position of the interposition means -1- or shield to be adjusted. This may be useful if the latch is wide or the tab of the door opener needs to be adjusted.
In Fig. 8 to 10, the interposed component -1- has been shown as not sufficiently flexible to deform. In some cases, however, this may be a desired effect, as by deforming the contact surface between the interposition means -1- and the cant of the first door leaf -100- would increase.
In the present specification, the term flexible or flexible material should be understood to mean capable of being bent/deformed under the forces experienced in normal use. In general, plastics materials and/or synthetic materials may be used as resilient materials, although metal may also be used, provided that the dimensioning thereof allows the effect indicated to be obtained.
Fig. 11 shows three possible embodiments -500-, -600-, -700- of the interposition means -1-. Elements that are the same or equivalent to those shown earlier have been identified with identical reference numerals and will not be explained in detail. In the embodiment -500-, there is a square central region -19- for the rod -12-. A straight strip enters said region -19- which on flexing rotates on the edge of the groove acting as a rod -12-. In this case, the articulated connection region -15- of the interposition means is a component that reduces friction in rotation, which occurs at the ends of -12-.
In the embodiment -600-, the arm -19- is thick and is therefore not flexible. The articulated connection region -15- are projections which do not have an opening for the rod or strip and which can act like the ends of the rod -12- in other embodiments, with the possibility of being used without said rod.
The embodiment -700- is intended to be the strong, hard and flexible embodiment (for example, metallic) of the interposition means. This embodiment is intended to combine in a single part the functions of interposition means -1- and arm -19-. Accordingly, the interposition means is Z-shaped. The embodiment has no anti-card grooves. It can also be used without a rod, for example by using another resilient return component (for example, the pin for the automatic function of a door opener).
In the three embodiments -500-, -600-, -700- the interposed component is a single part, and has no auxiliary screen device.
Although the invention has been set out and described with reference to embodiments thereof, it should be understood that these do not limit the invention, and that it is possible to alter many structural or other details that may prove obvious to persons skilled in the art after interpreting the subject matter disclosed in the present description, claims and drawings.
