Description

Safety device for closing two hinged elements, door opener and door comprising said device

The present invention relates to door and window closing systems, and more particularly, to a security device in the system for preventing an intruder from unauthorized opening of a door and window. More particularly, the invention relates to a safety device for closing two hinged elements, a door opener and a door comprising said device.

A lock connects the two hinge elements to each other. The hinge element or door element may comprise, for example, a leaf or panel of a door or window, or a frame of a door or window, etc.

Modern locks were originally horizontal wooden latches attached to the rear portion of the door, sliding through a primary guide rail to then fit into holes in the jambs or frames of the doors and windows. In order to give greater security to the lock, over time the mechanism evolved into a component made of metal, eventually evolving into a conventional round tube bolt. The introduction of a retractable deadbolt in modern locks is a significant advance because pushing the door is convenient and allows the door to close automatically due to the inclined surface of the deadbolt, in contrast to the bolt of its predecessor which must be moved manually to keep the door closed after it has passed through the aperture. However, this significant advance in user convenience has brought a hole to the door, with which intruders have so far been able to access unauthorized space at a low cost and leave no trace because they have not been forced into. All that is required is to insert a flexible card or sheet into the gap between the door leaf and the frame so that when the card or sheet slides vertically or horizontally, it comes into contact with the inclined area of the latch and, by means of a pushing movement, successfully moves the latch so that it retracts and the door opens.

Facing this problem, locksmiths have devised a number of solutions, most involving intervening components that attempt to prevent access to the latch from the outside. The component is an additional accessory that can be extended, mounted on the outside of the lock or frame, and intervene to try to prevent the sheet from contacting the latch.

An example of such a device is the factory ia de Ideas Pr iccas para el Hogar, a commercial accessory known as Magic Key from the s.l company.

These fittings, besides being not completely reliable because most can be bypassed, have the disadvantage that they are parts that protrude from the frame and can cause considerable changes to the original installation or are prone to accidents because the parts can get caught on the user's clothing or other parts. Also, over time, this disadvantage can cause damage to the system due to the hung items.

Furthermore, locking systems have been developed which automatically lock the bolt, as shown, for example, in document ES 1047686U. The system is quite efficient, although more costly and complex to install. For example, if the spacing between the frame and the lock is very large, those functions relating to the additional trigger fail because the larger spacing means that the loader is not under sufficient pressure and will not eventually latch the latch. Furthermore, if the door containing the system is correctly installed in the summer, but is working at its limit, the latch may not be locked when the winter comes and the door is retracted.

It is an object of the present invention to disclose a security device for all types of doors and windows which does not have the above-mentioned disadvantages.

More specifically, the invention discloses a safety device for closing two articulated elements, said device comprising intervention means intended to prevent access to the latches through the passage between the closed articulated elements. The interventional device has at least a non-operative position in which the device is retracted and an operative position in which the device is preferably maneuvered. The apparatus further comprises an actuation mechanism for actuating the interventional device when the door is closed.

The present invention discloses the use of a retractable intervention element or device that is actuated only in response to the closing of a door or window. This has a number of advantages not found in the prior art. The system is simple and does not deteriorate over time. Furthermore, since the system is movable and maneuverable, the forces it generates prevent unauthorized opening. Furthermore, the system may be designed such that in the non-operative position it does not extend beyond the lock, door opener or hinge element, thereby overcoming the problems of known intervention structures. The solution of the invention is particularly advantageous in the field of so-called door openers.

It is an object of the present invention to prevent unauthorized access by introducing a blocking element (e.g., flat and flexible) to prevent access to the latch. For this reason, preferably, access must be prevented not only directly through the horizontal position in which the latches are located, but also from points located above and below, i.e. by introducing the element at a point distant from the latches and then sliding it along the slot until the handle is reached. This is therefore not only to avoid a positive attack on the handle, but also from above or below. To this end, the access device of the present invention must preferably have dimensions larger than the latch, and more preferably the aperture is intended to provide space to access the latch or access to a receiving box (receiving box).

For example, the interventional device may take the form of a barrier or housing.

The device may be designed such that any situation related to the closing of the door activates the intervention means. For example, a closure sensor may be used or a latch enters its space during closure, making full use of its force to generate the deployment motion, or alternatively, metal contact of the latch with another component may be used to generate the deployment signal.

The intervention device (or housing) may be maneuvered in any manner and exhibit different kinematics between the non-operative position and the operative position. However, according to the invention, it is particularly advantageous if the intervention device is turnably or rotatably connected to the actuation mechanism such that the intervention device is rotated from the non-active position into the active position. This makes it possible to ensure that the device does not protrude in the inoperative position and also facilitates actuation, since the device can be arranged to rock about its axis of rotation, such that entry of the latch at one end causes the intervention device to appear at the other end.

In addition to rotation in the strict sense, the terms "rotation" and "rotatably" in the present application also include movements consisting of translations and displacements.

Preferably, the access device in the non-operative position extends beyond the space of the latch or the boundary or side of the receiving compartment. This provides additional protection when the interventional device is actuated, in particular when actuated by rotation, because if the size of the interventional device is equal to or smaller than the size of the cassette or space and further, when the interventional device is placed in the non-operative position, without exceeding the space along the extension plane of the interventional device or the boundaries of the latch receiving cassette, the lifted interventional device in the operative position will leave free space through which a forced unlocking can be performed. However, if the end of the maneuvered interventional device is initially positioned outside at least some of the limits or sides of the cassette, covering them, the available space is limited or even ineffective. The interventional device may extend beyond different sides of the space or box to avoid attacks from any direction, preferably with one end of the free interventional device parallel to the axis of rotation and turned out when the interventional device is activated, or beyond or covering one border or side of the space or box.

Thus, preferably, the actuation means comprise an arm that can be actuated and that is connected to the interventional device by a common rotation axis, such that actuation of the arm results in actuation of the rotation of the interventional device. The actuating arm may occupy part or all of the receiving area of the latch.

According to the invention, it is advantageous that the arm and/or the interventional device is flexible. In particular, by its non-permanent deformation, the flexible arm and/or the intervention device contribute to the complete entry of the latch, even when the intervention device abuts against the opposite door leaf before the latch reaches the end of its travel.

To help achieve this effect, the device preferably comprises a curved bar having the ability to rotate with respect to said common axis of rotation and having at least a first length in contact with the interventional device and a second length in contact with the arm.

The rod or bar may perform various functions including:

to assist bending of the arm, and/or

-transferring motion from the arm to the interventional device, and/or

Acting as an elastic device, the force of which tends to bring the interventional device into its inactive position.

Alternatively, the interventional device may have in an integrated manner a plurality of protrusions (e.g. shafts) positioned in respective rotational connection regions for pivoting of the interconnection device on said rotational connection regions. The device may have several rotary recesses parallel to which the shaft is received, in order to adjust the position of the interventional instrument.

In the closed position, the spacing between the closed hinge elements varies depending on the installation. If this spacing is very small, in some embodiments, there is a risk that the interventional device may not be sufficiently lifted or maneuvered. To minimize this risk, the invention enables the device to have an auxiliary intervention means or barrier in contact with the arm. The auxiliary access device may have a smaller size than the primary access device or barrier.

Preferably, the interventional device has a plurality of grooves on its outer face, preferably inclined with respect to the plane of the outer face and cut into the face in a direction away from the axis of rotation. The recesses are additional protection means which act as hooks for passing around the intervention device and reaching the inserted card of the latch. More preferably, the interventional device is profiled to form a slope in the direction of the groove. The purpose of this feature is to guide the card into the recess. For example, one end of the interventional device may be ramped.

One of the advantages of the 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 connecting plate (or strike plate) embedded in a hinged element (e.g. a frame or a door leaf), the plate having an aperture for receiving the latch. Preferably, the interventional device does not protrude beyond the plate. Preferably, the arm is located in the aperture for receiving the latch. Preferably, the device has lugs which are inserted into corresponding holes in the plate to enhance the mechanical stability of the entire mechanism.

Preferably, the interventional device has a through hole for allowing access to the elements in the cassette when the interventional device is in the non-operative position.

The invention also relates to a door opener comprising a device according to the invention. Preferably it comprises an outer surface for alignment with the side of the hinge element and in the non-active position it is housed in the lock and does not protrude beyond the outer surface. More preferably, the actuation mechanism is located in a space for receiving a latch of the lock such that entry of the latch into the space causes actuation of the device. Even more preferably, the door opener is an electromechanical, electromagnetic, motorized, pneumatic or hydraulic opening member.

The invention also discloses a door and/or window comprising the device or door opener according to the invention. Preferably, the door opener is embedded or arranged on the frame of the door and/or window.

The invention is particularly applicable to entry phone systems, although the invention may be applied to any type of lock, such as simple deadbolt type locks, which are actuated manually and/or by a key.

In summary, the present invention is considered to be a system that is exposed from the frame or door to protect the latches when the door is closed, and fully or partially retracted when the door is open. For example, one advantage of the present invention is that it can be a stand-alone system or can be incorporated into another system, such as a door opener. The present invention can be adapted to accommodate any installation or latching. Furthermore, the invention allows to provide additional protection systems, such as auxiliary barriers, ramps, for example for deflecting cards, hooks, etc., which makes it more difficult to break the system from any direction. In addition, a series of stops may be included to prevent over-rotation of the access element, thereby ensuring its integrity in the event of improper use. Finally, the invention also has the advantage of adapting the spacing between the door and the frame.

It may be inferred that the invention also discloses a lock frame or strike plate comprising a plate having an aperture for receiving a latch and an aperture for receiving a fastening element connected to a hinge element, said frame comprising a recess having a plate thickness, which recess is in contact with at least one side of said aperture on an outer surface of the plate. Preferably, the impact plate further comprises a hole for receiving a lug. More preferably, the length of the recess is greater than the length of the side. More preferably, the recess is in the form of a dovetail.

In the drawings, the same or equivalent elements are shown with the same reference numerals.

Fig. 1 and 2 show schematically a first embodiment of the invention. The components have been shown very schematically, the shape, spacing and proportions not being faithfully preserved. Furthermore, in the closed position, the rotation of the door leaf-100-about its hinge and thus its movement in a circular trajectory is omitted.

In fig. 1, two door leaves-100-, -101- (the second door leaf-101-may also be a door frame) can be seen. Latch-50-is shown on first door leaf-100-. On the second door leaf-101-there is shown an intervention device or barrier, which is in a non-active position, remains inside the door leaf-101-and does not protrude with respect to the outer surface of the edge of the second door leaf-101-. In fig. 2, the door has been closed and the interventional device-1-has been manoeuvred and has been moved to the active position.

The function of the interventional device-1-is to prevent unwanted access when attempting to force the door open. The intervention device according to the invention is therefore preferably manoeuvred until contact with the first door leaf-100-. In the example shown, the manoeuvring is performed by translation, in particular by linear displacement. The translation may be performed by means of elastic means or any other means (mechanical thrust, electric motor, hydraulic or pneumatic thrust, etc.). Any type of maneuver trajectory is possible. The event that causes the actuation of the intervention device-1-should be related to the closing of the door. More specifically, the device may be actuated by a sensor for the closing of the door, a sensor for the movement of the door leaf-100-, a sensor for the latch-50-entering its receiving space in the second door leaf-101-, or a sensor for any other event.

It is realised that preferably the intervention device is manoeuvred until contacting the outer surface of the hinging element (door leaf-100-) without entering any hole in the hinging element. In a preferred embodiment, there is no recess in the door leaf element-100-for receiving the intervention device-1-and no recess for receiving the intervention device-1-in the active (manoeuvred) position.

It is shown that the system is not affected by the free space between the door leaves-100-and-101-because the intervention device-1-can be manoeuvred until contact with the first door leaf-100-. Thus, the system is equally effective for maintaining a wide range of spacing between door leaves-100-, -101-or between door leaves and doors during installation of the doors. Another advantage can be seen in that the intervention device does not protrude beyond the edge of the second door leaf-101-.

Preferably, the size of the access device-1-is larger than the size of the latch-50-. It is even more advantageous that the size of the interventional device-1-is larger than the size of the hole into which the latch-50-is inserted. In particular, in this example, the result is that the intervention device-1-is larger than the latch and the recess for the latch in a direction perpendicular to the direction shown in fig. 1 and 2 (i.e. parallel to the joint between the swinging elements-100-and-101) -thus providing better protection against unauthorized access.

Fig. 3 to 10 show an exemplary embodiment of the present invention. In different drawings, the same or similar elements are shown with the same reference numerals. In particular, fig. 3 to 10 show an electric door opener-2-with a safety device according to the invention. This type of door opener is commonly used for access telephone systems and access control and presents a security problem in the latch as the door is held closed only by the action of the latch.

In the example shown, the area comprising the lower region of the rod-12-goes up to the connection-111-which in this example acts as a spring.

In the example shown in fig. 3, a part of the embeddable door opener-2-contains a so-called catch, i.e. a space-28-or recess for receiving the latch, and in this particular example a part for normally opening the latch. The opening function is achieved by releasing an internal mechanism that allows the catch-29-to rotate freely. When pushing the door, the user pushes the catch-29-of the door opener through the latch-50-of the lock, causing the catch to rotate until the latch of the lock is released, at which point the door is opened.

The examples shown in figures 3 to 10 can be produced by door openers of known type by replacing the connecting plate-21 to which the intervention device-1-is connected. The connection plate-21-has a recess for receiving the interventional device-1-so that it does not protrude. This is easily accomplished because in most door openers the door opener mechanism is attached to the plate-21-by means of screws-22-. The purpose of the plate-21-is to remain substantially flush with the side (can) of the door leaf or frame on which it is mounted, and therefore not protrude from the door leaf or frame. Thus, plate-21-includes an outer surface for aligning with the side of the hinge element.

As shown, the interventional device-1-is rotatably connected (in this case, by a rotational connection region-15-in this case, the connection region-15-takes the form of a protrusion, the function of which is to reduce friction and facilitate rotation). In the inactive position, the intervention device remains inside the frame and does not protrude from the door opener (and therefore from the side on which the device is mounted) until moved by rotation to the active position.

In the rest position shown in fig. 3, it can be observed how the interventional device-1-exceeds the space-28 of the latch on the plane in which the interventional device lies-or the border of the receiving magazine. In particular, in the illustrated case, the access device extends beyond the side of the latch box near the end-113-which is turned out during rotation of the access device. In this case, said portion beyond the box boundary is housed in a recess-213-in the plate-21-to prevent the intervention device-1-from protruding from the connection plate-21-in the inactive position. However, the interventional device, although extending beyond the boundaries of the sides of the cassette, does not protrude from the plate in a direction perpendicular to the plate.

For example, elastic means may be provided to ensure that the interventional device returns from the active position to the inactive position. In the example shown, this can be achieved by the action of a rod-12-, magnet, spring or bar. Thus, in some cases, it is also possible to use known operating components in the door opener, such as an automatic function pin or a microswitch actuation element.

In this example, the interventional device-1-is actuated by a latch. To this end, the apparatus includes an arm-19-. The arm is located in an opening for receiving the latch, the opening being defined, for example, by a plate-21-. The arm is connected to the interventional device-1-on the side opposite the rotational axis of the interventional device-1-so that entry of the latch pushes the arm-19-towards the inside of the catch, causing the interventional device to move out. In the particular example shown in fig. 3 to 10 and 12, the arm-19-is flexible, which allows the arm to continue to bend, allowing the latch to enter even if the interventional device has come into contact with the door leaf, and the latch therefore no longer rotates. To facilitate the bending, the rod-12-is bent and has a length in contact with the arm-19-. The length of rod-12-in contact with arm-19-is away from the axis of rotation to assist in the lever arm and bending. Furthermore, the rod-12-is in contact with the interventional device-1-on the opposite side (with respect to the axis of rotation) to the contact with the arm-19-so that the rod can also act as a transmitter of the movement of the arm-19-to the interventional device-1-as well.

Access device-1-has grooves-13-, -14- (see fig. 6) and/or steps, the purpose of which is to act as hooks to deflect or block attempts to use a card having a particular shape (e.g., L-shape) to attack the access device from above or below. If the card comes into contact with one of the grooves-13-, -14-, said groove catches the card and blocks it when the intervention device is manoeuvred. Thus, in one possible example, the groove is inclined with respect to the plane of the external face of the interventional device-1-on which it is located, and cuts into this face/interventional device in a direction away from the axis of rotation. Preferably, the grooves are located near the axis of rotation, although they may be located anywhere.

The effect of the grooves-13-, -14-is supplemented by sloping or triangular free ends-113-. Said area-18-forms a slope at the periphery of the interventional device, which slope guides the cards inserted into the grooves-13-, -14-. Also, the fact that the length of the free end-113-in the direction of the axis of rotation of the interventional device-1-is greater than the length of the receiving area of the latch-50-prevents unauthorized access to the device via the card or the rod from violating the security of the device.

In the example shown, the interventional device has two parts and also includes an auxiliary barrier-11-. The purpose of this arrangement is to help the device to accommodate very small spacings between the door leaves or between the groove and the door leaf. In this case, the interventional device should not prevent the latch from entering fully.

This structure can be seen in fig. 4, 5 and 8 to 10. For clarity, some elements that have been shown have been omitted from the drawing. In all the figures, most of the door opener is omitted except for the opening mechanism-29- (which is not essential for implementing the invention, which can be applied to other types of closing devices). In fig. 4 and 5, the baffles of the interventional device-1-have also been omitted, however they can be seen in fig. 8 to 10.

The auxiliary barrier-11-as well as the arm-19-and the connecting part-111-are preferably parts made of a flexible material, which are connected to the interventional device-1-. Arm-19-and auxiliary barrier-11-may be connected such that bending of arm-19-always lifts the auxiliary barrier, which lifting of the auxiliary barrier occurs independently of the interventional device-1-if not lifted. In this case, the auxiliary barrier-11-may perform the function of the interventional device. The connecting part-111-in this example is comprised in the arm-19-although they may work alone and function as a spring actuation, the spring tending to retract the device when the door is open and both the arm-19-and the connecting part-111-may be connected to the interventional device-1-. The connection is for example made through an opening-112-in the arm-19- (see fig. 5) and a protrusion or lug-113' -on the lower face of the interventional device-1 (see fig. 8 to 10).

Fig. 8-10 illustrate the process of closing and mobilizing the security mechanism. Figure 8 shows the moment latch-50-comes into contact with arm-19-when the door is closed. The interventional device does not protrude from the outer surface-21-and remains incorporated within the frame. In fig. 9, the latch is further advanced, pressing and pushing the arm-19-inward and moving the interventional device-1-out as the assembly pivots about its axis of rotation (coinciding with the main or rotational axis of the rod-12). For this reason it is advantageous if the spring force exerted by the arm-19-is smaller than the spring force of the latch spring. Fig. 10 shows that the latch has been inserted to the end, but in this case the arm has been bent so far that it does not cause further rotation of the main part of the interventional device. Thus, it is advantageous that the arms yield sufficiently to allow this effect without overcoming the force of the latch spring (not shown). It can be seen that the interventional device-1-has not moved, but that the auxiliary barrier-11-has been manoeuvred until it substantially touches the door leaf-100-.

The interventional device may have various recesses for placing the interventional device in different positions relative to the axis of rotation. This allows to adjust the position of the interventional device-1-or the barrier. It may be useful if the deadbolt is wide or if it is necessary to adjust the door lock by adjusting the door opener tab.

In fig. 8-10, the intervening component-1-is shown as not being flexible enough to deform. However, in some cases this may be a desired effect, since the contact surface between the intervention device-1-and the side of the first door leaf-100-is increased by the deformation.

In this specification the term flexible or compliant material is to be understood as being capable of bending/deforming under the forces experienced in normal use, whilst returning to its original form when the external forces in question cease. Generally, plastic materials and/or synthetic materials can be used as the elastic material, although metals can also be used, as long as their dimensions allow the indicated effect to be obtained.

FIG. 11 shows three possible embodiments-500-, -600-, -700-of the interventional device-1-. Elements that are the same or equivalent to the elements described above have been identified with the same reference numerals and will not be described in detail. In example-500-, there is a square central region-19-which serves as the rod 12. The straight strip enters said zone-19-which rotates on the edge of the groove by bending, thus acting as a rod-12. In this case, the articulation region-15-of the interventional device is a component that reduces the rotational friction that occurs at the end of the equivalent rod-12-.

In example-600-, arm-19-is thicker and therefore less flexible. The hinged connection area-15-is a protrusion that may be integrated or form part of the intervention element-1-and that does not have an opening for a rod or strip, and in other embodiments it may function like the end of a rod-12-and may be used without said rod.

Example-700-a strong, stiff and flexible example (e.g. metallic) intended to be an interventional device. This embodiment is intended to combine the functions of the interventional device-1-and the arm-19-into a single part. Thus, the interventional device is Z-shaped. This embodiment does not have an anti-chucking groove, but the anti-chucking groove may be applied last. It can also be used without a lever, for example by using another elastic return member (for example a pin for the automatic function of the door opener).

In these three embodiments-500-, -600-, -700-the intervening components are single components and there is no auxiliary barrier device.

Fig. 12 to 16 show a further embodiment of the device according to the invention. Like elements similar or equivalent to those of the embodiments shown above are identified with the same numerals.

As shown, the interventional device-1-is of the rotary type. The free end-113-of the interventional device-1-beyond the cartridge-28-is parallel to one side of the rotational axis of the interventional device. Furthermore, the length of the free end-113-is greater than the length of the side on the cassette. Furthermore, the interventional device has a hole-110-, which hole-110-allows access to the bottom of the cassette, in order to be able to access the terminal for adjusting or disassembling the assembly without the need to operate or disassemble the interventional device.

In addition, the device has locking lugs-51-which are inserted into corresponding holes-215-of the plate-21. Lugs-51-stiffen the system.

In fig. 14, plate-21-is shown with a hole-223-for receiving the free end of the interventional device-213-for receiving the free end of the interventional device (protruding from the recess), and a corresponding hole-215-for the lug. Hole-216-for tightening the edge of the hinge element (not shown in the figures) is also observed.

In this example, the lug-51-is shown integrated in the plate-5-see fig. 15, the plate-5-together with the other plate-6-being interposed between the built-in door opener-2-and the plate-21-. In addition to the lugs, the plate-5-has a blank area-523-corresponding to the hole of the space-28-of the door opener-2-where the hole-59-corresponds to the hole-216-of the screw of the plate-21-. It also has several slots-559-for receiving the axis of rotation of the interventional device-1-. The other plate-6-prevents the intervention element-1-from coming out of the housing of the intervention element-1-in the plate-5-during operation and adjustment. It has a reinforcement-61-ensuring an optimal spacing between the mechanism and the plate-21-in the door opener-2-, protecting the device-111-and ensuring a correct positioning of the other plate-5-. On the other hand, other adjustment systems may also adjust the position of the access element, for example by elongating the hole-59-to adjust the displacement of the assembly formed by the plates-5-and-6-with respect to the screw-22-. In this case, the adjustment can be ensured by serrations on the rear portion of the plate-5-and the contact surface with the door opener-2-or the plate-21- (not shown).

In this example, the rod has been omitted and integrated into the components forming the interventional device, thus becoming robust. In particular, a shaft is arranged on each side of the interventional device and integrated in the interventional device. The interventional device pivots about the axis. This construction is more robust than the construction of the rod.

While the invention has been illustrated and described with reference to embodiments thereof, it is to be understood that the embodiments are not limited thereto and that many changes in the details of construction and other details may become apparent to those skilled in the art upon reading the subject matter disclosed in the specification, claims and drawings. In particular, in principle, all features of each of the different embodiments and of the variants shown and/or of the proposed variants can be combined with one another. The scope of the invention thus includes any variations or equivalents which may be considered to be covered by the broadest scope of the appended claims.
