Description

SECURING WINDOWS, DOORS, GLASSES, GRILLS, ROOMS, OTHER OPENINGS AND ENCLOSURES IN BUILDINGS TO DETECT INTRUSIONS

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY

[001] The present application claims priority from Indian patent application No.: 201641028894 filed on 24^th August 2016.

TECHNICAL FIELD

[002] The present disclosure, in general, relates to a security system installed in buildings, and more particularly, to security system installed in windows, doors, glass, grills, rooms, and other enclosures used for security, by using different type of glass, grill bars and frames.

BACKGROUND

[003] Intrusion sensitive systems are employed to prevent intruders from entering a building. The windows and doors are broken or stealthily unlocked to breach the security of buildings. Many a times, the doors and windows are made of glass thereby providing an easy point of access and/or entry for the intruders into buildings. Therefore, in order to ensure further security, an additional security layer in form of grill doors and grill windows are installed in the building. However, in the recent times, even the grills doors and the grill windows have found to be broken easily with minimal effort.

[004] Thus, in order to ensure foolproof security and protection from the intruders, the owners of the building have to constantly keep a check on their building which is not always feasible. For example, the owners may be travelling out of stations and hence may be away from their building for a long duration. Further, even if the owners are in the building however due to lacunae discussed above, the existing security mechanisms fail to proactively provide any intrusion alerts if the intruder attempts an unauthorized access/entry into the building.

[005] Thus, in light of the above lacunae, there is a long felt need in the art for a system and method that would not only alert the owners in case of an intrusion but also helps in identifying the intruders. SUMMARY

[006] Before the present methods, systems and components of the systems are described, it is to be understood that this disclosure is not limited to the particular systems/methods/apparatus and its arrangement as described, as there can be multiple possible embodiments which are not expressly illustrated in the present disclosure. It is also to be understood that the terminology used in the description is for the purpose of describing the particular versions or embodiments only, and is not intended to limit the scope of the present application. This summary is not intended to identify essential features of the claimed subject matter nor is it intended for use in detecting or limiting the scope of the claimed subject matter.

The first conducting medium or the second conducting medium may be fixed on surfaces or partially/fully embedded into a surface. The surface may be the window/door frame, or the wall, or the floor, or the roof of the room or the building, or any other security enclosure. In one embodiment, the second conducting material is placed into the grill bars by machining a groove into one part of the bar across the length of the bar and welding a second part of the bar onto the first part of the bar. Further, the trip wire circuit may comprise of an alarming system adapted to be triggered on failure of the trip wire circuit, wherein the failure of trip wire circuit is detected based upon breaking of at least one of the first conducting material and/or of the second conducting material. The triggering of the alarming system is indicative of an intrusion into a building.

[008] In accordance with aspect of the present disclosure, the first conducting material is in form of conducting wires or conducting material strips. The second conducting material is a thin insulated metal wire. Each of the conducting wires or conducting strips is placed across the body of the glass or within the bars of the grill.

[0021] Some embodiments of this disclosure, illustrating all its features, will now be discussed in detail.

[0022] The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items.

[0023] It must also be noted that as used herein and in the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Although any systems and methods similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present disclosure, the preferred, systems and methods are now described. The disclosed embodiments are merely example of the disclosure, which may be embodied in various forms.

[0024] The present subject matter discloses a novel system for security purpose to be installed window/door frame/ grills/enclosures or any other opening where one or more combination of glass and bars, wires are used.

[0025] Figure 1 describes a security system 10 comprising of three components, a trip wire circuit with hooters alarms 20, an intrusion sensitive window/door glass 30 and an intrusion sensitive grill 40. In one embodiment, the security system 10 may employ the intrusion sensitive window/door glass 30 for providing security to the building. In another embodiment, the security system 10 may employ the intrusion sensitive grill 40 for providing security to the building. In still another embodiment, the security system 10 may collectively employ both the intrusion sensitive glass 30 and the intrusion sensitive grill 40 for providing security to the building. The intrusion sensitive window 30 and the intrusion sensitive grill 40 may form an integral part of the trip wire circuit 20. It is to be noted that the intrusion sensitive window/door glass and intrusion sensitive grill along with trip wire circuit collectively forms the security system 10. Each of the three components of the security system 10 are described in detail in subsequent paragraphs referring to the appended figures.

[0026] Referring to figure 2, a trip wire circuit 20 (also referred hereinafter as circuit 20 interchangeably) for the security system 10 is shown. The circuit 20 comprises of different essential components like power supply, a rechargeable battery 25, a rectifier 21, a power drain alarm 22, a trip wire circuit alarm system 23, and a trip wire bus 24 connected to window/doors/grills. The power supply for the circuit 20 can be provided by various sources for e.g. solar powered system, charger, batteries, AC power through rectifier etc. The rechargeable battery 25 is provided to ensure proper power supper. The power drain alarm 22 comprises a first set of alarms which may be audio and/or visual alarms. The power drain alarm 22 generates an alert signal, via the first set of alarms, when the trip wire circuit 20 is running out of power. Thus, it is ensured that the circuit 20 is always charged and functioning.

[0027] The next component in the trip wire circuit 20 is the trip wire circuit alarm system 23. The trip wire circuit alarms system 23 comprises of a second set of alarms which may be visual and/or audio alarms. The second set of alarms comprises of bright visual alarms and loud hooter alarms. The trip wire circuit alarms system 23 may have a record and a transmission functionality. The record and transmission functionality may get triggered in case of intrusions. In an embodiment, when an intrusion is detected, the visual information comprising of pictures of intruders may get recorded (optionally) and relayed to the stakeholders. The stakeholders may comprise of owners of building, personnel engaged in security of building, law enforcement and other emergency response organizations. The transmission of visual/audio information may be continuous or intermittent.

[0028] The trip wire circuit 20 (shown in figure 2) consists of a trip wire bus 24 connected to window/doors/grills. The trip wire bus 24 is embedded into the inner window frame 52 (shown in figure 5) of the window/door/grills. The trip wire bus may comprise of a strip of stiff or flexible insulated material containing lines of conducting material or simply bunch of wires. The trip wire bus is further connected to the glass panes 30 (shown in figure 5) of the window/door or the bars 41 shown in figure 5) of the grill. The trip wire circuit 20 is integrated into the windows or doors or grills through the trip wire bus 24. The windows/doors or grills are designed in such a way so as to become active participant in the trip wire circuit 20. As the trip wire circuit 20 is sufficiently enclosed within glasses or grills, external manipulation of the trip wire circuit 20 is difficult. The design of window/door glass and grill bars to work as security system for the building is hereinafter explained in detail as below.

[0029] The window/door glass and the grill bars are adapted to work as security system 10 based upon breaking of the trip wire circuit 20 which may be due to breakage of the window/door glass and the grill bars by an intruder, thereby facilitating the detection of the intrusion into the building. For example, when the trip wire circuit 20 breaks, the second set of alarms may be triggered and activated. Further, one or more stake holders of the building may be notified via short service message (SMS) or a multimedia message. Also person or persons at a remote location (for e.g. watchman at the entrance gate, police, etc.) may be notified on the intrusion. The breaking of the trip circuit may be due to breakage of the glass or grill or both, the details of which are explained below.

[0030] Figure 3 illustrates a front view 34, a side view 35, a top view 36 of an intrusion sensitive window glass 30. The intrusion sensitive construction for an intrusion sensitive window glass 30 comprises of a first glass pane 32 and a second glass pane 33 collectively forming the entire glass of the window. Between the two glass panes (32,33) a first conducting material 37 (also referred hereinafter as thin conducting wires 37 interchangeably) made of a conducting medium is placed between two conducting points 31. The first conducting material 37 may be thin conducting wires or strips made of conducting medium. The thin conducting wires 37 are laid across the area of the glass. The spaced out design of sandwiching conducting wires 37 in between two glass panes (32,33) makes it impossible to break the window glass 30 without breaking the conducting wire 37. Alternatively, instead of using conducting wires 37, thin strips of conducting materials may be used. Since, an intrusion sensitive window glass 30 is an integral part of the trip wire circuit 20, the breaking of the glass in turn breaks the conducting wire sandwiched in between the glass panes thereby resulting in the breaking of the trip wire circuit which triggers and activates the second set of alarms.

[0031] As shown in figure 4, intrusion sensitive grill 40 are also designed in a way to provide security against attempts of theft or breakage. A cavity 42 is designed into the grill bars 41 along the entire length of the grill bars 41. The cavity 42 holds a second conducting material 44 (also referred hereinafter as thin strand of conducting wire 44 interchangeably). Inside the drilled cavity 42, thin strand of conducting wire 44 along with insulation 43 for the conducting wire is inserted. Since, the intrusion sensitive grill 40 is integral part of the trip wire circuit 20, the breaking of the grill bar 41 in turn breaks the conducting wire 44, embedded within the grill bars 41 thereby resulting in the breaking of the trip wire circuit which triggers and activates the second set of alarms. The grill bars 41 as shown in figure 4, can be of various shapes including circular, triangular, square and the like. According to an embodiment of the present subject matter, the intrusion sensitive grill 40 may be used in peripheral security like on compounds or in and as barbed wires (typically seen in fences, hence also referred as fencing wire).

[0032] As shown in figure 5, the security system design layout 50 comprises of an inner window frame 52, an outer window frame 51 and trip wire bus 24. The grill bars 41 and the intrusion sensitive glass 30 along with the sandwiched conducting wires 37 in the intrusion sensitive glass 30 and the embedded conducting wire (not seen) in the grill bars 41 are integrated with the trip wire bus 24. It is to be noted that one or more of such trip wire bus 24 may be deployed into the frames.

[0033] As a whole security system shown in design layout 50, the conducting wires are seen to be parallel to each other. The parallel placement of the conducting wires makes it difficult to break, cut or forcefully open the window glass or grill without breaking any of the conducting wires. Once one or more of the conducting wires are broken, the trip circuit breaks and alarms are activated.

[0034] As a part of security system, one or more cameras (not shown) are placed on either side of the window frames (52,51). The placing of camera on both sides of the frames (52,51) provides better surveillance coverage. The cameras can monitor the space and can capture the images of the intruder. The image captured by the camera may be sent to owner and other stakeholders via a short service message or a multimedia message. Thus, it becomes easy to capture the intruder.

[0035] The window/door frames (52,51) (shown in figure 5) may comprise a box (not shown) placed on the window/door frame (52,51) or in the window/door frames (52,51). The box (not shown) contains all electronic components, alarm system components, wires, etc. The box (not shown) may or may not be visible from outside. The box may also be fixed within the wall adjacent to window/door.

[0036] Now referring to Figure 6, a method for detecting an intrusion in a building is illustrated. As shown in Figure 6, at step 61 a first conducting material 37 (shown in figure 3) may be sandwiched between at least two glass panes of window/door frames (52,51) (shown in figure 5). The first conducting material 37 (shown in figure 3) may be a thin conducting wire 37 or a thin conducting strip made of conducting medium.

[0037] At step 62, a second conducting material 44 may be embedded within grill bars 41 (shown in figure 4) of the window/door frames (52,51) (shown in figure 5).

[0038] At step 63, an alarming system 23 may be triggered based upon on failure of the trip wire circuit 20 (shown in figure 2) in response to breakage of the glass 30 (shown in Figure 3) or grill bar 41 (shown in Figure 4) or both.

[0039] The security system 10 implementing the above mentioned steps 61, 62, 63 (shown in figure 6) secures/protects the building from the intrusions.

[0040] Referring to figure 7(a), the trip wire circuit layout 70 of the trip wire bus 24 is shown as implemented in grillbars, according one embodiment of present subject matter. The conducting wires passing through the grill bars 41 are connected to the trip wire bus 24. The conducting wires or strips 72 form trip wire bus 24. The conducting bus wires 71, forming the trip wire bus 24 is connected, through a multi-pin connector (not shown), to other parts of the circuit (not shown in the diagram).

[0041] Similarly, referring to figure 7(b), the trip wire circuit layout 73 of the trip wire bus 24 is shown as implemented in glass panes, according one embodiment of present subject matter. The conducting wires 31 passing through the glass panes 30 are connected to the trip wire bus 24. The conducting wires or strips 72 form trip wire bus 24. The conducting bus wires 71, forming the trip wire bus 24 is connected, through a multipin connector (not shown), to other parts of the circuit (not shown in the diagram).

[0042] Referring to figure 8 a is trip wire circuit layout 80 through window/door frame hinges 81.

The panel side 83 of the hinges 81 and frame side 85 of the hinges 81 holds hinges 81 with support 82 holding flanges of hinges 81. Conducting wires 84 pass from panel side 83 to frame side 85. The passing of conducting wires 84 from panel side 83 to frame side 85 through body of hinges provides security to trip wire circuit.

[0043] Exemplary embodiments discussed above may provide certain advantages. Though not required to practice aspects of the disclosure, these advantages may include those provided by the following features.

[0044] Some embodiments enable a system and a method to protect a building from theft and intrusion by employing a security system securing the window/door glass and the grill bars, constructed to secure any openings (doors, windows, balcony) or enclosures.

[0045] Some embodiments enable a system and a method for designing a secure window/door glass and grill bars such that, breakage of either or both of the window/door glass and the grill bars triggers an alarm and/or instructs the camera to capture an image of intruder to be sent to the stakeholders in the security of the building.

[0046] According to an embodiment of present subject matter, the conducting wires/strips may be embedded in wood also.

[0047] Some embodiments enable a system and a method to protect a building from theft and intrusion when the occupants are active in the building. The proposed system is free from any loophole. Existing systems, which are vibration, sound, IR light, Laser light based systems are prone to triggering false alarms, like when light rays are disturbed by passing of pets like dogs, cats etc. Hence, typically these are not active when the occupants are active at building and hence these devices have to specifically armed when occupants are not in the building and expect the security system to work. The proposed system may be in armed mode 24 X 7, as there is very minimal probability of false alarms being triggered. The intrusion alarms can be triggered only by physical disruption of secure windows, doors, grills or other enclosures, wherein the other enclosures may comprise a rolling or sliding shutter, a wall, a floor, a roof of a room or a building and the like

[0048] Some embodiment of the present disclosure may enable using the intrusion sensitive glass to secure glass enclosures like glass display units used in jeweler shops, museums etc.

[0049] Some embodiment of the present disclosure may enable using the intrusion sensitive bars in grills of balconies, peripheral security as fencing wire. The first conducting medium may be fixed on the surface wherein the surface may be the window/door frame, or the wall, or the floor, or the roof of the room or the building, or any other security enclosure. The intrusion sensitive bars of second conducting medium may be partially or fully embedded into the grills and the grills in which the intrusion sensitive bars of second conducting medium is embedded, may further be embedded into the grills of a rolling or sliding shutter or between two cementitious layers of a wall, a floor, or a roof of a room or a building. One or more sensors may also be embedded into the wall, or the floor, or the roof which is adjacent to at least one of the door, the window, the rolling or sliding shutter or any other openings. The one or more sensors may sense the movement or motion of at least of the door, the window, the rolling or sliding shutter or any other openings and may further trigger the alarm, wherein the triggering of the alarm may be indicative of an attempt of an intrusion into the building. The one or more sensors may comprise electrical sensor, mechanical sensor, electromagnetic sensor, motion sensor, proximity sensor and the like.

[0050] The preceding description has been presented with reference to various embodiments of the disclosure. However, persons skilled in the art and technology to which this disclosure pertains will appreciate that alterations and changes in the described apparatus and methods of operation can be practiced without meaningfully departing from the principle, spirit and scope of this disclosure.
