Description

279378/ A WINDOW GUARD AND METHOD OF ASSEMBY THEREOF TECHNICAL FIELD [0001]The present disclosure generally relates to a window guard and method of assembling thereof, and more specifically to a modular window guard adjustable according to the width and/or length of a window opening onto which the window guard is installed to prevent passage therethrough, and method of assembly thereof. BACKGROUND [0002]Window gratings are installed in order to prevent passage through the window onto which they are installed. For example, to prevent fall of children or pets from an open window. There are various shapes and forms of window gratings, however, their assembly generally requires a professional, and may not be accomplished by a layman, since assembling such gratings typically involves accurately measuring the size of the window onto which the grating should be assembled, drilling holes into a house or building's external walls, and connecting the grating through the drilled holes to the walls surrounding the window. [0003]Due to the current method of assembly, window gratings are considered permanently attached onto their corresponding window and may not be easily removed in order to be moved to a different location, for example, to be assembled onto a different window. [0004]There is thus a need for a window grating or window guard that would prevent passage therethrough while being easily assembled and easily reassembled by any layman such to be moveable at any required time. SUMMARY [0005] According to an aspect of some embodiments of the present disclosure, there is provided a window guard for preventing passage through a window opening, which may 279378/ be easily installed by any layman, having accurate measuring and use of professional equipment become redundant.

[0051]With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of 279378/ embodiments of the disclosure. In this regard, the description taken with the drawings makes apparent to those skilled in the art how embodiments of the disclosure may be practiced. [0052]Identical or duplicate or equivalent or similar structures, elements, or parts that appear in one or more drawings are generally labeled with the same reference numeral, optionally with an additional letter or letters to distinguish between similar entities or variants of entities, and may not be repeatedly labeled and/or described. References to previously presented elements are implied without necessarily further citing the drawing or description in which they appear. [0053]Dimensions of components and features shown in the figures are chosen for convenience or clarity of presentation and are not necessarily shown to scale or true perspective. For convenience or clarity, some elements or structures are not shown or shown only partially and/or with different perspective or from different point of views. DETAILED DESCRIPTION [0054]Some embodiments of the present disclosure provide a window guard or window grating that prevents passage therethrough and more specifically through a window opening defined by a window frame and window rail, onto which the window guard is installed. According to some embodiments, the window guard of the present disclosure can adjust its width and length to the width and length of the opening it is to protect such to overcome the need for high accuracy when measuring the opening size. That is, the window guard of the present disclosure allows for some deviation in measuring its size by being modular and size adjustable. Furthermore, the window guard of the present disclosure may be easily assembled and installed by any layman due to avoiding the need for heavy and professional equipment, as it is installed onto an existing window rail and is secured and reinforced to itself without penetration through the window frame. Although easy to install, the window guard provides full protection against fall or passage through a window opening onto which it is installed. [0055]The modularity and ease of installation of the window guard of the present disclosure, may also allow for ease of disassembly of the window guard, when a user wishes to move the window guard to a different location. For example, a renter may 279378/ assemble the window guard in one apartment, and before moving to a new apartment, may disassemble the window guard and then easily re-assemble it on his own at the new apartment. [0056]Reference is now made to FIGS. 1 and 2, which are schematic illustrations of a front perspective view and a front view of an assembled window guard for preventing passage through a window opening, respectively, according to some embodiments of the present disclosure. In some embodiments, window opening 100 may comprise a window frame 102, which defines the size of the window opening 100. The width of window frame 102 may be denoted by 'W'. In some embodiments, window frame 102 may comprise at least one window rail onto which a window guard may be installed. In some embodiments, window frame 102 may comprise a two-rail sliding window. Window frame 102 may comprise two rails; a front rail 120 for a front-sliding window (not shown) to slide thereon and a back rail 130 for a back-sliding window 104 to slide thereon. [0057]When a two-wing sliding window is closed, the front-sliding window and the back-sliding window are positioned one next to another. To open a two-wing sliding window, a user may either slide the front-sliding window to be located in front of the back-sliding window, or the user may slide the back sliding window to be located behind the front-sliding window. According to the present disclosure, when the back-sliding window, e.g., back-sliding window 104, is pushed along back rail 130 all the way against one side of the window frame 102, and the front-sliding window is pushed along front rail 120 such to be located in front of back-sliding window 104, thereby also being pushed against that same side of frame 102 that back-sliding window 104 is pushed against, an opening is created in window frame 102. In case the two-wing sliding window comprises sliding wings of the same size, the opening created is of a width equal to half the width of the entire window opening 100, i.e., W/2, though other opening widths may be created at other windows. [0058]In order to guard the opening created when sliding the front-sliding window and the back-sliding window against one side of window frame 102, a window guard 110 may be assembled and installed into window frame 102 along a window rail. According to some embodiments, the size of window guard 110 should fit the size of the actual opening created in widow frame 102, such to provide full protection from passage through the window opening. In some embodiments, window frame 102 may enclose a foldable window, a 279378/ sliding window, a window opening about hinges or any other type of window. However, no matter the window type, window guard 110 requires a window rail onto which it may be installed. [0059]In case the window frame encloses a two-sliding window, and in case the front and back sliding windows are identical, the width of window guard 110 should be adjusted to fit the width of half a window frame 102, i.e., W/2. Similarly, the width of any window guard according to the present disclosure, should fit the width of the actual opening created within the window frame 102, e.g., by moving sliding windows against one side of window frame 102. That is, window guard 110 of the present disclosure need not be sized to fit the entire space created by window frame 102 but should rather merely fit the actual size of the opening created, e.g., after sliding both window wings all the way against one side of the window frame. This provides a significant reduction in expenses compared to current methodology, which includes manufacturing a window grating in the size of the entire window frame. When producing a smaller sized window guard, e.g., half the width of an entire window frame in case each of the two wings is of the same size i.e., half the size of the window frame, the manufacturing costs and thus the costs imposed on the customer are substantially reduced. In addition, since any layman may measure the required size of the window guard 110 and may assemble the window guard 110 alone without the need for a professional, costs are further reduced. [0060]According to some embodiments, window guard 110 may comprise two opposing longitudinal supports 112, which may be located on both sides of window guard 110. In some embodiments, the two opposing longitudinal supports 112 may be made of aluminum, though other materials may be used, such as stainless steel. In some embodiments, window guard 110 may further comprise at least one bar 114 located between and connected to the two opposing longitudinal supports 112. Typically, a plurality of bars 114 may be located between and attached to the two opposing longitudinal supports 112 to prevent passage through the window guard 110. Bars 114 may be made of various materials or a combination of materials, for example, steel, metal, stainless steel, aluminum, or different polymers such as polycarbonate that would provide sufficient strength while being transparent or semi-transparent. Transparent bars 114 may be more esthetic compared to opaque bars, since they to provide the ability to see through them, 279378/ though either opaque or transparent bars may be implemented. In some embodiments, instead of bars 114, window guard 110 may comprise at least one cable or a mesh or a net tightened between the two opposing longitudinal supports 112 to prevent passage through window guard 110. The at least one cable, mesh or net may be made of different materials such as metal, steel, stainless steel, aluminum, polymers such as polycarbonate, other rigid yet flexible materials or any combination thereof. [0061]In some embodiments, each of the two opposing longitudinal supports 112 may comprise a recess 340 (FIG. 4A) created at the end of each longitudinal support 112, to enable to fit the longitudinal supports 112 onto a window rail. In some embodiments, the size and shape of the recess 340 may correspond to the size and shape of the window rail, such that longitudinal supports 112 may be easily installed onto the window rail. For example, if the shape of the protruding window rail is round, then recess 340 would also have a corresponding round shape. In some embodiments, each longitudinal support 1may comprise a top recess configured to fit a top window rail, and a bottom recess configured to fit a bottom window rail. [0062]In some embodiments, each of two longitudinal supports 112 may comprise at least one hole 150, e.g., a thread insert, into which an attachment element/fastener may be inserted, e.g., a screw, perpendicularly to the longitudinal axis of each of longitudinal support 112. The attachment element/fastener that may be inserted through a thread insert 150 may provide mechanical tightening of window guard 110 to window frame 1without penetrating through window frame 102. In case window frame 102 encloses front and back sliding windows, tightening of an attachment element/fastener such as a screw into thread insert 150 may in fact tighten window guard 110 against window frame 102 on one side of window guard 110, and against back window 104 on the opposite side of window guard 110, such to ensure solid installation of window guard 110 onto the opening in window frame 102. [0063]In some embodiments, the entire tolerance for adjusting the width of window guard 110 may be several centimeters, though other lengths may be implemented. In some embodiments, there may be more than one thread insert 150 located along each of longitudinal supports 112. 279378/ id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64"

[0064]Reference is now made to FIGS. 3-4B, which are schematic illustrations of a perspective view of multiple horizontal bars connected to two longitudinal supports, which form basis to a window guard, of a front perspective view of a window guard, and a top view of a window guard, respectively, according to some embodiments of the present disclosure. In some embodiments, window guard 110 may comprise two external longitudinal supports 112, comprising horizontal bars 114 located therebetween. In some embodiments, external longitudinal supports 112 may be configured to cover two opposing inner longitudinal supports 124, such that the at least one bar 114 is in fact connected to the two opposing inner longitudinal supports 124. [0065]In some embodiments, the two opposing inner longitudinal supports 124 may each be a simple angle iron onto which at least one bar 114 is connected. Such that each of the at least one bar 114 may be connected on one end to a first inner longitudinal support 1and on the opposite end to a second inner longitudinal support 124. The at least one bar 114 may be connected to each of the two opposing inner longitudinal supports 124 via connecting means/fasteners 134, e.g., screws, though other attachment mechanisms may be used, for example, rivets, glue and tight pressure. [0066]In some embodiments, and as detailed with respect to FIG. 3, window guard 1may comprise two opposing inner longitudinal supports 124, between which at least one horizontal bar 114 may be connected. Each of the two opposing inner longitudinal supports 124 may be covered with one of two external opposing longitudinal supports 112. [0067]The presence of the two opposing external longitudinal supports 112 covering the two opposing inner longitudinal supports 124 provides the ability to adjust the width of window guard 110 to conform to the width of the opening in window frame 102, without penetration through window frame 102. In some embodiments, each of two inner longitudinal supports 124 may comprise a hole 312, e.g., an insert comprising a nut, into which a fastener, e.g., a screw may be screwed. Each of two external longitudinal supports 112 may comprise at least one hole, e.g., a thread insert 150 (FIG. 4A) corresponding to nut 312, through which the fastener, e.g., a screw may be inserted. The more external longitudinal support 112 is moved farther away from its opposite external longitudinal support 112, the wider the width of window guard 110 becomes, and vice versa- the closer an external longitudinal support 112 is brought towards the opposite external longitudinal 279378/ 29.6.20 support 112, the less the width of window guard 110 is, within the restrictions of a predetermined distance D (FIG. 4B) maintained between each of the external longitudinal supports 112 and each of the two inner longitudinal supports. In some embodiments, one of the external longitudinal supports 112 may be brought closer or farther away from its opposite longitudinal support 112, whereas in other embodiments, each of the two external longitudinal supports 112 may be brought closer or farther away from each of the corresponding opposite external longitudinal supports 112. The fastener inserted into hole 150 may fixate the desired location of each external longitudinal support against the sides of the window opening, thereby fixating the width of window guard 110. [0068]Furthermore, a fastener, e.g., a screw that is inserted through thread insert 150 into nut 312 may provide mechanical tightening between the two longitudinal supports 112 and the two inner longitudinal support 124 as well as provide mechanical tightening of window guard 110 against window frame 102 without penetrating through window frame 102. In case window frame 102 encloses front and back sliding windows, tightening of a screw into thread insert 150 through nut 312 may in fact tighten window guard 110 against window frame 102 on one side of window guard 110, and against back window 104 on the opposite side of window guard 110, such to ensure solid installation of window guard 1onto the opening in window frame 102. [0069]In some embodiments, each of inner longitudinal supports 124 need not comprise any hole, e.g., nut hole 312. In such case, a fastener may be inserted into at least one hole 150 of each of external longitudinal supports 112 and be tightened against inner longitudinal supports 124 such to cause external longitudinal supports 112 to get closer to inner longitudinal supports 124 and fixate the width of window guard 110 such to conform to the width of the window opening. [0070]FIG. 4B illustrates one of external longitudinal supports 112 after it had been moved along its corresponding inner longitudinal support 124 to the entire extent of the tolerance D for adjusting the width of window guard 110. If the width of window guard 110 should be reduced, external longitudinal support 112 may move along bar 114 via a corresponding opening 512 (FIG. 5) in external longitudinal support 112 for bar 114 to pass therethrough, towards the opposite external longitudinal support 112 at a maximum distance D. In some embodiments, each of external longitudinal supports 112 may move 279378/ 29.6.20 back and forth along the at least one bar 114 through opening 512 such to adjust the width of window guard 110 to the window opening until the two external longitudinal supports 112 are pushed against the sides of the window frame between which the window opening is present. The predetermined distance or tolerance that external longitudinal support 1may move along for width adjustment may be D. Once the distance between the two external longitudinal supports 112 is determined such that the width of window guard 1conforms to the width of the window opening, a fastener may be tightened into hole 150 in order to fixate external longitudinal support 112 at the determined distance against inner longitudinal support 124. Tightening of the fastener may apply pressure onto the sides of the window frame 102 by applying pressure onto external longitudinal supports 1thereby fixating window guard 110 to the sides of window frame 102 between which the window opening is present. That is, tightening the fastener into the corresponding holes 312 and 150 without penetration through the window frame, pushes the two external longitudinal supports against the two inner longitudinal supports and further pushes the two external longitudinal supports against opposing sides of the window frame 102 to thereby fixate the window guard against the opposing sides of the window frame, as can also be seen from FIG. 6. [0071]In some embodiments, each of the recesses 340 (FIG. 4A) may comprise a friction element 342, located within the recess 340 between recess 340 and the rail of the window frame, e.g., back rail 130, onto which recess 340 rests, to create friction between each longitudinal support 112 and the window rail. The shape of the friction element 3conforms to the shape of recess 340 such to fit into recess 340 while also fitting the shape of the window rail onto which it is installed. The friction element 342 may prevent movement of each of the longitudinal supports 112 with respect to the window rail. e.g., back rail 130. [0072]According to FIG. 4A, each of longitudinal supports 112 may comprise at least one recess 340, which may be located on the bottom end 112b of longitudinal support 1and/or on the upper end 112t of longitudinal support 112. The shape and size of each recess 340 is configured to fit a bottom window rail and a corresponding top window rail, e.g., top and bottom back rail 130. 279378/ id="p-73" id="p-73" id="p-73" id="p-73" id="p-73" id="p-73" id="p-73"

[0073]Reference is now made to FIG. 5, which is a schematic illustration of a front perspective enlarged view of a friction element that is located between a window rail and a window guard according to some embodiments of the present disclosure. As illustrated in FIG. 5, friction element 342 may be configured to fit the shape of recess 340 as well as the shape of the window rail onto which window guard 110 is assembled. Friction element 342 may be inserted into recess 340 before assembling window guard 110 onto a corresponding widow rail, e.g., back rail 130, or friction element 342 may be inserted into recess 340 after window guard 1110 is assembled onto the corresponding window rail, i.e., after recess 340 of window guard 110 is placed onto a corresponding window rail. [0074]In some embodiments, friction element 342 may be made of a rigid yet flexible material such as rubber or a polymeric material, to increase friction between window guard 110 and the window rails onto which window guard 110 is assembled, thus, to ensure solid attachment of window guard 110 onto the window opening. [0075]Reference is now made to FIGS. 6A-6C, which are schematic illustrations of a side view of a window guard located onto a window rail, an enlarged view of a recess of a window guard and a front view of a window guard, respectively, according to some embodiments of the present disclosure. [0076]FIG. 6B illustrates the position of a recess 340 along a window rail 130 in an enlarged illustration of that in FIG. 6A. The position of a top or upper recess 340 along a corresponding upper back window rail 130 as well as the position of a bottom recess 3along a corresponding bottom back rail 130 is illustrated in FIG. 6A. [0077]In FIG. 6C, the side holes or thread inserts 150 of longitudinal supports 112 are shown. As mentioned with respect to FIG. 4A, these side thread inserts 150 are configured for adjusting and fixating the width of window guard 110 to conform to the width of the window opening within window frame 102, which may be created, e.g., after back sliding window 104 is pushed all the way towards the left side of window frame 102. In some embodiments, longitudinal supports 112 comprise inner longitudinal supports 124 to which the at least one horizontal bar 114 is connected, and which may be covered by longitudinal supports 112. As window guard 110 is manufactured such to comprise a predetermined distance D (FIG. 4B) between inner longitudinal supports 124 and external longitudinal supports 112. Width adjustment of window guard 110 is enabled by moving external 279378/ longitudinal supports 112 back and forth along inner longitudinal supports 124 along distance D, until width of window guard 110 conforms to the width of the window opening, followed by tightening of an attachment element/fastener, e.g., a screw, through hole 150, e.g., thread insert 150, possibly into corresponding nuts 312 of inner longitudinal supports 124. The farther the two external longitudinal supports 112 are moved away from one anther (along and within the restrictions of distance D), the wider the width of window guard 110 is, and vice versa. During manufacture, a distance D is maintained between each of the inner longitudinal supports 124 and each of external longitudinal supports 112, in order to provide the ability to adjust the width of the window guard 110 according to the opening in window frame 102. Reducing or increasing the distance between the two external longitudinal supports 112 within the restrictions of distance D, enable adjusting the width of window guard 110 to the width of the opening in window frame 102. [0078]In some embodiments, the distance D between each of the inner longitudinal supports 124 and each of longitudinal supports 112 may be a few centimeters, e.g., 2cm. That is, the entire tolerance for adjusting the width of window guard 110 to conform to the width of the window opening may be twice the distance present on one side of window guard 110, e.g., when the distance on one side is 2cm, the entire tolerance provided may be 4cm. It should be noted that other distances may be implemented, and the distances D need not be identical between the opposing sides of window guard 110. In some embodiments, there may be more than one thread insert 150 located along each of longitudinal supports 112. [0079]Reference is now made to FIG. 7, which is a schematic illustration of a front perspective view of a window guard for preventing passage through a window opening, according to some embodiments of the present disclosure. id="p-80" id="p-80" id="p-80" id="p-80" id="p-80" id="p-80" id="p-80"

[0080]Reference is now made to FIGS. 7 and 8, which are schematic illustrations of a front perspective view and a front view of an assembled window guard for preventing passage through a window opening, respectively, according to some embodiments of the present disclosure. In some embodiments, window opening 100 may comprise a window frame 102, which defines the size of the window 100. The length of window frame 1may be denoted by 'L' and the width of window frame 102 may be denoted by 'W'. In some 279378/ embodiments, window frame 102 may comprise at least one window rail onto which a window guard may be installed. In some embodiments, window frame 102 may comprise a two-rail sliding window. Window frame 102 may comprise two rails; a front rail 120 for a front-sliding window (not shown) to slide thereon and a back rail 130 for a back-sliding window 104 to slide thereon. [0081]When a two-wing sliding window is closed, the front-sliding window and the back-sliding window are positioned one next to another. To open a two-wing sliding window, a user may either slide the front-sliding window to be located in front of the back-sliding window, or the user may slide the back-sliding window to be located behind the front-sliding window. According to the present disclosure, when the back-sliding window is pushed along back rail 130 all the way against one side of the window frame 102, and the front-sliding window is pushed along front rail 120 such to be located in front of it, thereby also being pushed against that same side of frame 102 that back-sliding window 104 is pushed against, an opening is created in window frame 102. In case the two-wing sliding window comprises sliding wings of the same size, the opening created is of a width equal to half the width of the entire window opening 100, i.e., W/2, though other opening widths may be created at other windows. [0082]In order to guard the opening created when sliding the front-sliding window and the back-sliding window against one side of window frame 102, a window guard 1110 may be assembled and installed into window frame 102 along a window rail. According to some embodiments, the size of window guard 1110 should fit the size of the opening created in widow frame 102, such to provide full protection from passage through the window opening. In some embodiments, window frame 102 may enclose a foldable window, a sliding window, a window opening about hinges or any other type of window. However, no matter the window type, window guard 1110 requires a window rail onto which it may be installed. [0083]In case the front and back sliding windows are identical, the length of window guard 1110 should be adjusted such to fit the length L of window frame 102, and the width of window guard 1110 should be adjusted to fit the width of half a window frame 102, i.e., W/2. Similarly, the length of any window guard according to the present disclosure, should fit the length of a window frame into which it is installed, and fit the width of the opening 279378/ created within the window frame by moving the sliding windows against one side of the window frame. That is, the window guard 110 of the present disclosure need not be sized to fit the entire space created by window frame 102 but should rather merely fit the actual size of the opening created after sliding both window wings all the way against one side of the window frame. This provides a significant reduction in expenses compared to current methodology, which includes manufacturing a window grating in the size of the entire window frame. When producing a smaller sized window guard, e.g., half the width of an entire window frame in case each of the two wings is of the same size i.e., half the size of the window frame, the manufacturing costs and thus the costs incurred on the customer are substantially reduced. In addition, since any layman may measure the required size of the window guard 1110 and may assemble the window guard 1110 alone without the need for a professional, costs are further reduced. [0084]According to some embodiments, window guard 1110 may comprise two opposing longitudinal supports 1112, which may be located on both sides of window guard 1110. In some embodiments, the two opposing longitudinal supports 1112 may be made of aluminum, though other materials may be used. In some embodiments, window guard 11may further comprise at least one bar 1114 located between and connected to the two opposing longitudinal supports 1112. Typically, a plurality of bars 1114 may be located and attached to the two opposing longitudinal supports 1112 to prevent passage through the window guard 1110. Bars 1114 may be made of various materials or combination of materials, for example, steel, metal, stainless steel, aluminum, or different polymers such as polycarbonate that would provide sufficient strength while being transparent or semi-transparent. Transparent bars 1114 may be more esthetic compared to opaque bars, since they to provide the ability to see through them, though either may be implemented. In some embodiments, instead of bars 1114, window guard 1110 may comprise at least one cable or a mesh or a net tightened between the two opposing longitudinal supports 1112 to prevent passage through window guard 1110. The at least one cable, mesh or net may be made of different materials such as metal, steel, stainless steel, aluminum, polymers such as polycarbonate, other rigid yet flexible materials or any combination thereof. [0085]In some embodiments, window guard 1110 may comprise at least two modular connectors 1116. Modular connectors 1116 may be configured to fit onto a rail of the 279378/ window frame, e.g., a back rail. In some embodiments, the at least two modular connector 1116 may attach to one end of the two opposing longitudinal supports 1112. In some embodiments, window guard 1110 may comprise at least two modular connectors 1116, whereby each of the at least two modular connectors 1116 may attach to one end of each of the two opposing longitudinal supports 1112, while each being typically attached to the same end of either of the two opposing longitudinal supports 1112. For example, in case a first modular connector 1116 is attached to the bottom end of a first longitudinal support 1112, a second modular connector 1116 may be attached to the bottom end of the second longitudinal support 1112. In some embodiments, a third modular connector may be attached to the top end of the first longitudinal support 1112, and a fourth modular connector 1116 may be attached to the top end of the second longitudinal support 1112. [0086]In some embodiments, the modular connector(s) 1116 enable length adjustment of window guard 1110. A user may measure the opening size in a window frame 102 for ordering a window guard 1110. Since the user may be a layman, who is not a professional, the measurement may not be accurate. Furthermore, even when a professional was to measure the opening size, some deviation in measurements compared to the actual opening size may be made. Thus, the two opposing longitudinal supports 1112 may be manufactured at a length that is shorter than that of the measured opening length and the modular connector(s) 1116 attached to the two opposing longitudinal supports 1112 may compensate for the length difference, such that the modular connector(s) 1116 may be moved along the two opposing longitudinal supports 1112 to add to the required length of window guard 1110, as will be explained later in detail. [0087]In some embodiments, the least two modular connectors 1116 may be configured to adjust the length of window guard 1110 to conform to the length of the window frame 102 without penetration through window frame 102, thereby enabling ease of assembly and ease of disassembly of window guard 1110. [0088]Reference is now made to FIG. 9, which is a schematic illustration of a perspective view of multiple horizontal bars connected to two longitudinal supports, which form basis to the window guard, according to some embodiments of the present disclosure. In some embodiments, window guard 1110 may comprise two longitudinal supports 1112, comprising horizontal bars 1114 located therebetween, and having attached at least two 279378/ modular connectors 1116, though at least one modular connector 1116 may be implemented, as illustrated in FIG. 14 and will be explained in detail hereinbelow. [0089]In some embodiments, longitudinal bars 1112 are actually configured to cover two opposing inner longitudinal supports 1124, such that the at least one bar 1114 is in fact connected to the two opposing inner longitudinal supports 1124, and the modular connectors 1116 are attached onto external longitudinal supports 1112 after the longitudinal supports 1112 cover the inner longitudinal supports 1124. [0090]In some embodiments, the two opposing inner longitudinal supports 1124 may each be a simple angle iron onto which at least one bar 1114 is connected. Such that each of the at least one bar 1114 may be connected on one end to a first inner longitudinal support 1124 and on the opposite end to a second inner longitudinal support 1124. The at least one bar 1114 may be connected to each of the two opposing inner longitudinal supports 11via screws, though other attachment mechanisms may be used, for example, rivets, glue and tight pressure. [0091]Reference is now made to FIG. 10, which is a schematic illustration of a front perspective view of a window guard for preventing passage through a window opening, according to some embodiments of the present disclosure. [0092]In some embodiments, and as detailed with respect to FIG. 9, window guard 11may comprise two opposing inner longitudinal supports 1124, between which at least one horizontal bar 1114 may be connected. Each of the two opposing inner longitudinal supports 1124 may be covered with one of two opposing external longitudinal supports 1112. [0093]The presence of the two external longitudinal supports 1112 covering the opposing inner longitudinal supports 1124 provides the ability to adjust the width of window guard 1110 to conform to the width of the opening in window frame 102, without penetration through window frame 102. In some embodiments, each of two inner longitudinal supports 1124 may comprise a hole, e.g., an insert comprising a nut 1312, into which a fastener, e.g., a screw may be screwed. Each of two external longitudinal supports 1112 may comprise a hole 1412, e.g., a thread insert corresponding to nut 1312 through which a fastener, e.g., a screw may be inserted. The screw may be tightened into hole 14following width related tolerance adjustment, for fixating the width of window guard 1110 279378/ such to conform to the width of the opening in window frame 102 that window guard 11is assembled onto to prevent passage therethrough. Furthermore, the screw that is screwed through hole 1412, e.g., thread insert 1412, into nut 1312 may provide mechanical tightening of window guard 1110 to window frame 102 without penetrating through window frame 102. In case window frame 102 encloses front and back sliding windows, tightening of a screw into hole 1412 through nut 1312 may in fact tighten window guard 1110 against window frame 102 on one side of window guard 1110, and against back window 1104 on the opposite side of window guard 1110, such to ensure solid installation of window guard 1110 onto the opening in window frame 102. [0094]In some embodiments, each of inner longitudinal supports 1124 need not comprise any hole, e.g., nut hole 1312. In such case, a fastener may be inserted into at least one hole 1412 of each of external longitudinal supports 1112 and be tightened against inner longitudinal supports 1124 such to cause external longitudinal supports 1112 to get closer to inner longitudinal supports 1124, to fixate the determined width of window guard 1110, which conforms to the width of the window opening. [0095]Reference is now made to FIG. 11, which is a schematic illustration of a modular connector of a window guard, according to some embodiments of the present disclosure. In some embodiments, modular connector(s) 1116 may be used to adjust the length of the window guard 1110 such to conform to the length of the opening in window frame 102. At least one modular connector 1116 may be used, which may be attached onto an end of each of the two longitudinal supports 1112 (FIG. 14). In other embodiments, at least two modular connectors 1116 may be attached onto an end of each of the two longitudinal supports 1112 typically onto the same end, i.e., a first modular connector 1116 may be attached onto the bottom end of a first longitudinal support 1112, while a second modular connector 1116 may be attached onto the bottom end of the second longitudinal support 1112. In other embodiments, the modular connectors 1116 may be attached on the top end of each of the two longitudinal supports 1112. In some embodiments, four modular connectors 1116 may be used, each on either end of the first and second longitudinal supports 1112. [0096]In some embodiments, each of longitudinal supports 1112 may comprise an elongated hole 1516. In some embodiments, elongated hole 1516 may be located in close 279378/ proximity to either or both ends of each longitudinal support, i.e., elongated hole 1516 may be located near the bottom end of each longitudinal support 1112 or near the upper end of each longitudinal support 1112 or near both the bottom end and near the upper end of each of longitudinal supports 1112. In some embodiments, the at least one modular connector 1116 or in case more than one is used, each modular connector 1116 may comprise a corresponding hole 1526, which may be covered with a hollow cork 1528, which may be made of a flexible material such as rubber, though other materials may be used. [0097]When a user wants to connect a modular connector 1116 to an end of each of the two longitudinal supports 1112, the user may insert a fastener, e.g., a screw or other connecting element 1536 through the corresponding hole 1526 of modular connector 11into the elongated hole 1516 of longitudinal supports 1112. The location of corresponding hole 1526 of modular connection 1116 along elongated hole 516 determines the desired length of each of the two longitudinal supports 1112, after which a screw may be tightened to fixate the connection between the modular connector 1116 and each of the two longitudinal supports 1112. That is, a user may determine where along elongated hole 15to fixate modular connector 1116 via tightening a connecting element 1536, e.g., a screw, between corresponding hole 1526 and elongated hole 1516. [0098]In some embodiments, cork 1528 may be located within corresponding hole 15such that the proximal end of connecting element 1536 that is inserted into hole 1526, may be securely covered by cork 1528 such to prevent injury. That is, cork 1528 may cushion the proximal end of connecting element 1536, which may be a head of a screw. [0099]In some embodiments, the length of elongated hole 1516 may be several centimeters, e.g., between 1 to 5cm, though other lengths may be implemented. In case, for example, elongated hole is 3cm long, the tolerance that may be provided by it may be of approximately 2.5cm, since there is some overlap between the length of modular connector 1116 and the height of the window rail onto which modular connector 1116 is installed. [00100] In some embodiments, modular connector 1116 may comprise a recess 1546, which may be of the same shape as the shape of the window rail onto which modular connector 1116 is to be fitted. For example, if back rail 1130 (FIG. 7) onto which modular connector 1116 is to be fitted has a round shape, then recess 1546 may also have a round shape such to easily fit onto back rail 1130. 279378/ id="p-101" id="p-101" id="p-101" id="p-101" id="p-101" id="p-101" id="p-101"

[00101] In some embodiments, each of the modular connectors 1116 may comprise a friction element, located within recess 1546 between each of the modular connectors 1116 and the rail of the window frame, e.g., back rail 130, to create friction between each of modular connectors 1116 and the window rail. The shape of the friction element conforms to the shape of recess 1546 such to fit into recess 1546 while also fitting the shape of the window rail onto which it is installed. The friction element may prevent movement of each of the modular connectors 1116 and thereby prevent movement of each of the two longitudinal supports with respect to the window rail. e.g., window back rail 130.It should be appreciated that the connection between corresponding hole 1526 and elongated hole 1516 does not involve any penetration through window frame 102. The adjustment of the length of longitudinal supports 1112 to the length of the opening in window frame 1merely involves an adjustment of the position of modular connector 1116 with respect to elongated hole 1516, and the connection of modular connector 1116 to each of the two longitudinal connectors. No attachment means are required to further fixate the modular connector 1116 or the longitudinal supports 1112 to window frame 102. [00102] Reference is now made to FIGS. 12A-12B, which are schematic illustrations of a perspective front view of an assembled window guard and an enlarged view of a modular connector of the window guard, respectively, according to some embodiments of the present disclosure. As illustrated in FIGS. 12A-12B, modular connector 1116, which may be attached to one of the two longitudinal supports 1112 at the bottom end of longitudinal support 1112, may be attached to the longitudinal support 11via connecting element 1536 inserted into elongated hole 1516 (FIG. 11) through corresponding hole 1526, which may pass through flexible cork 1528. In some embodiments, modular connector 1116 may be fitted along a window rail, e.g., back rail 130 by placing recess 1546 over back rail 130. [00103] As can be seen, window guard 1110 may be located along the back rail 130, adjacent to back sliding window 104, while the front rail 120 is free for moving a front sliding window all the way back and forth. Thereby, in case the back-sliding window 1is pushed all the way towards the left side of window frame 102, window guard 1110 will be assembled to the right of back sliding window 104 along back rail 130. When the front sliding window will be located along front rail 120 to the right of back sliding window 104, 279378/ there would be no opening in window frame 102, and passage through window opening 100 would be prevented, since the back sliding window would block the left side of the window opening 100, while the front sliding window would block the right side of the window opening 100. And when the front sliding window would be located along front rail 120 and pushed all the way towards the left side of window frame 102 such to be located in front of back sliding widow 104, window guard 1110 is what would prevent passage on the right side of window opening 100, while the front and back sliding windows would prevent passage through the left side of window opening 100. [00104] Reference is now made to FIGS. 13A-13C, which are schematic illustrations of a side view of a window guard located onto a window rail, an enlarged view of a modular connector of a window guard and a front view of a window guard, respectively, according to some embodiments of the present disclosure. According to FIG. 13A, two modular connectors 1116 may be attached to a longitudinal support 1112, on the bottom end of longitudinal support 1112 and on the upper end of longitudinal support 1112. In some embodiments, each of longitudinal supports 1112 may be manufactured to be somewhat shorter than the length provided by the user, such that the exact length of each of the two longitudinal supports 1112 may be adjusted during assembly, by positioning and fixating modular connectors 1116 at the appropriate location along elongated hole 1516 of each of longitudinal support 1112. In case there are two modular connectors 1116 per each longitudinal support, one of the modular connectors 1116 per each longitudinal support, e.g., the modular connector 1116 located at the upper end of longitudinal support 1112, may first be fixated to longitudinal support 1112 via connecting element 1536, then window guard 1110 may be positioned along the bottom and top sides of back rail 130 via positioning of the respective top and bottom modular connectors 1116, after which the modular connectors 1116 located at the upper end of longitudinal supports 1112 are fixated to the corresponding longitudinal supports 1112, while adjusting the length of the longitudinal supports 1112 to the length of the window frame 102 by adjusting the location of the upper modular connectors 1116 along elongated hole 1516. [00105]FIG. 13B illustrates the position of a bottom modular connector 1116 along a window rail 130, as does FIG. 12B. FIG. 13A illustrates the position of a top or upper 279378/ modular connector 1116 along a corresponding upper back window rail 130 as well as the position of a bottom modular connector 1116 along a window rail 130. [00106]In FIG. 13C, the side holes 1412 of longitudinal supports 1112 are shown. As mentioned with respect to FIG. 10, these side holes 1412 are configured for adjusting the width of window guard 1110 to conform to the width of the window opening within window frame 102, created after back sliding window 104 is pushed all the way towards the left side of window frame 102. In some embodiments, longitudinal supports 11comprise inner longitudinal supports 1124 to which the at least one horizontal bar 1114 is connected, and which are covered by longitudinal supports 1112. As there is a distance (e.g., distance D as in FIG. 4B) between inner longitudinal supports 1112 and external longitudinal supports 1112, that distance may enable movement back and forth along at least one bar 1114 of external longitudinal supports 1112 closer or farther away from an opposite external longitudinal supports 1112, with the restrictions of the predetermined distance, to adjust the width of window guard 1110 to the width of the window opening, such to decrease or increase the width, respectively. In some embodiments, tightening of a screw, through holes 1412 possibly into nuts 1312 (FIG. 9) of inner longitudinal supports 1112 may fixate the width of window guard 1110. The screw tightens external longitudinal supports 1112 towards inner longitudinal supports 1124 to further fixate window guard 1110 against the sides of the window opening. During manufacture, a distance is maintained between each of inner longitudinal supports 1124 and each of external longitudinal supports 1112, in order to provide the ability to adjust the width of the window guard 1110 to the opening in window frame 102. In some embodiments, the distance between each of inner longitudinal supports 1124 and each of external longitudinal supports 1112 may be a few centimeters, e.g., 2cm. That is, the entire tolerance for adjusting the width of window guard 1110 may be twice the distance present on one side of window guard 1110, e.g., when the distance on one side is 2cm, the entire tolerance provided may be 4cm. It should be noted that other distances may be implemented, which may be different on either side of window guard 1110. In some embodiments, there may be more than one hole 1412 located along each of longitudinal supports 1112. [00107]Reference is now made to FIG. 14, which is a schematic illustration of a front perspective view of a window guard for preventing passage through a window opening, 279378/ according to some embodiments of the present disclosure. According to some embodiments, a window guard 1410 may comprise two opposing longitudinal supports 1422, which may be located on both sides of window guard 1410. In some embodiments, the two opposing longitudinal supports 1422 may be made of aluminum, though other materials may be used. [00108]In some embodiments, window guard 1410 may further comprise at least one bar 1414 located between and connected to the two opposing longitudinal supports 1422. Typically, a plurality of bars 1414 may be located and attached to the two opposing longitudinal supports 1422 to prevent passage through the window guard 1410. Bars 14may be made of various materials or combination of materials, for example, steel, metal, stainless steel, aluminum, or different polymers such as polycarbonate that would provide sufficient strength while also being transparent or semi-transparent. Transparent bars 14may be more esthetic compared to opaque bars, since they to provide the ability to see through them, though either may be implemented. In some embodiments, instead of bars 1414, window guard 1410 may comprise at least one cable or a mesh or a net tightened between the two opposing longitudinal supports 1412 to prevent passage through window guard 1410. The at least one cable, mesh or net may be made of different materials such as metal, steel, stainless steel, aluminum, polymers such as polycarbonate, other rigid yet flexible materials or any combination thereof. [00109] In some embodiments, window guard 1410 may comprise at least one modular connector 1416. Modular connector 1416 may be configured to fit onto a rail of the window frame, e.g., a back rail. In some embodiments, the at least two modular connector 14may attach to one end of the two opposing longitudinal supports 1422. In some embodiments, window guard 1410 may comprise at least one modular connector 1416, attached to the same end of the two opposing longitudinal supports 1422. For example, modular connector 1416 may be attached to the upper end of each of said two longitudinal support 1422 (or to the bottom end of each of said two longitudinal supports 1422).

[00110] In some embodiments, the modular connector 1416 may enable length adjustment of window guard 1410. A user may measure the opening size in a window frame 102 before ordering window guard 1410. Since the user may be a layman, who is not a professional, the measurement may not be accurate. Furthermore, even when a professional was to measure the opening size, some deviation in measurements compared to the actual opening size may be made. Thus, the two opposing longitudinal supports 14may be manufactured at a length that is shorter than that of the measured opening length and the modular connector 1416 attached to the two opposing longitudinal supports 14may compensate for the length difference, such that the modular connector 1416 may be moved along the two opposing longitudinal supports 1422 to add to the required length of window guard 1410 such to fit the length of the window opening. [00111]In some embodiments, the least one modular connector 1416 may be configured to adjust the length of window guard 1410 to conform to the length of the window frame 102 without penetration through window frame 102, thereby enabling ease of assembly and ease of disassembly of window guard 1410. [00112]In some embodiments, modular connector 1416 may comprise a thread insert 1450 through which an attaching means such as a screw may be inserted in order to fixate the modular connector 1416 at a specific longitudinal location along each of the two opposing longitudinal supports 1422 once the desired length of window guard 1410 is determined according to the length of the window opening. In some embodiments, modular connector 1416 may be able to move up or down such to extend and increase the length of window guard 1410 or to shorten the length of window guard 1410, respectively. [00113] In some embodiments, the attaching means, e.g., screw, which is to be inserted into thread insert 1450 for fixation of the length of window guard 1410, may be inserted from the inside of window guard 1410 into the thread inserts 1450 of the two opposing longitudinal supports 1422. [00114]In some embodiments, an additional modular connector may be attached to an opposite end of the two longitudinal supports 1422, e.g., at the bottom end. In some embodiments, the additional modular connector 1416 may be fixated to the two opposing longitudinal supports 1422 without being able to move, whereas in other embodiments, the 279378/ additional modular connector may also enable length adjustment as does the first modular connector 1416. [00115]Reference is now made to FIG. 15, which is a schematic illustration of a mosquito net to be attached onto a window guard, according to some embodiments of the present disclosure. In some embodiments, an additional element may be attached onto window guard 1110, such as an anti-sun net that reduces sun radiation passing therethrough, decorations, or mosquito net 1802. A mosquito net such as mosquito net 1802 may comprise a frame 1804, which may be approximately the size of window guard 1110, and a mesh or net 1806 filling the space created by frame 1804. The size of mosquito net 18may be determined based on the measurements made by the user when ordering window guard 1110. In some embodiments, the size of mosquito net 1802 may be manufactured with a larger length than that measured by the user, and any extra beyond the length of window guard 1110, may be covered by the protruding sides of the window rail, e.g., back rail 130. With respect to the width of mosquito net 1802, the connection of mosquito net 1802 to window guard 1110 may be done between frame 1804 and longitudinal supports 1112, such that the width of each of longitudinal supports 1112 may provide some tolerance. In some embodiments, the user may be able to cut the proper size of mesh or net 806 according to the size of the opening in window frame 102.The mosquito net 1802 may be attached onto window guard 1110 via various attachment means, for example, magnets, Velcro, hooks, glue, and other permanent or temporary attachment means. In some embodiments, the location of the attachment means along mosquito net 1802 and the locations of the corresponding attachment means along window guard 1110 correspond to one another. [00116]In some embodiments, mosquito net 1802 may comprise at least one magnet or any other attachment means, typically located along frame 1804, while at least another opposite magnet or any other corresponding attachment means may be attached onto window guard 1110. In some embodiments, the corresponding attachment means may be attached along longitudinal supports 1112, along any of bars 1114, along modular connectors 1116, along the window rail, e.g., back rail 130, and so on, as long as the location of the magnet attached onto mosquito net 1802 and the locations of a corresponding magnet attached along window guard 1110, correspond to one another. Due 279378/ to the attracting magnetic forces between the at least one magnet located along mosquito net 1802 and a corresponding magnet located onto window guard 1110, the mosquito net 1802 is attached to window guard 1110. A magnetic connection may be easily overcome by pulling pressure from the user, such to enable the user to easily detach the mosquito net 1802 from window guard 1110, when necessary, such as when the user wishes to clean mosquito net 1802. In some embodiments, Velcro may be attached onto frame 1804 and corresponding Velcro may be attached along window guard 1110, at various locations, as long as the locations along which Velcro is applied matches between mosquito net 18and window guard 1110. Velcro is also an example of an easily detachable attachment means. In other embodiments, permanent attachment means may be implemented, such as glue. That is, glue may be applied by a user for attaching mosquito net 1802 to window guard 1110, in a substantially permanent manner. In some embodiments, mosquito net 1802 may be positioned onto the window opening via hooks, such that window guard 11may comprise a recess into which mosquito net 1802 is attached. [00117] Reference is now made to FIG. 16, which is a schematic flowchart illustrating a method 1600 for assembling a window guard for preventing passage through a window opening, according to some embodiments of the present disclosure. In some embodiments, method 1600 for assembling a window guard, e.g., window guard 110, may comprise operation 1602, which comprises providing a window guard comprising two opposing inner longitudinal supports, e.g., inner longitudinal supports 124, at least one bar, e.g., bar 114, located between and connected to the two opposing inner longitudinal supports 124, and two external longitudinal supports, e.g., external longitudinal supports 112. In some embodiments, each of the external longitudinal supports, e.g., supports 112, may comprise a recess, e.g., recess 340, on at least one end of each of the external longitudinal supports 112 for fitting onto a window rail, e.g., back rail 130. In some embodiments, each of the two external longitudinal supports may further comprise at least one hole, e.g., thread insert 150, configured to accept a fastener therein, e.g., a screw, without penetration through the window frame. [00118] In some embodiments, method 1600 may further comprise operation 1604, which may comprise positioning the two external longitudinal supports via the recess onto opposing rails of the window frame, for example, onto a back rail located at the top end of 279378/ window frame 102 and onto a corresponding back rail located at the bottom end of window frame 102. [00119] In some embodiments, method 1600 may comprise operation 1606, which may comprise adjusting the width of the window guard to conform to the width of the opening in the window frame by adjusting a distance between the two external longitudinal supports, which may move along the at least one bar through opening 512 or 1512 until coming in contact with the inner longitudinal supports. That is, adjusting the distance between the two external longitudinal supports may be done by moving the two external longitudinal supports farther or closer to one another along the predetermined distance to increase or reduce the distance between the two external longitudinal supports until they are pushed against and contact the opposite sides of the window frame between which the window opening is present. In some embodiments, the method may further comprise fixating the distance and thereby the width of the window guard by tightening a fastener into the hole, without penetration through the window frame. A fastener/attachment element may be inserted into the at least one hole, e.g., a thread insert to fixate the adjusted width of the window guard and firmly push each external longitudinal support against an opposing side of the window frame between which the window opening is present. In some embodiments, the more the fastener is tightened into the hole, the farther an external longitudinal support is moved away from its opposite external longitudinal support to each be pushed against a side of the window frame, the wider the window guard becomes, and vice versa. [00120]In some embodiments, operation 1606 may comprise positioning the two external longitudinal supports onto a rail of the window frame and then pushing each of the two against the opposing sides of the window frame between which the window opening is present, to thereby adjust the width of the window guard to the width of the opening. This may be followed by tightening of a fastener to further push and fixate each external longitudinal support against its corresponding side of the window frame between which the opening is present. In some embodiments, operation 1606 may further comprise inserting a friction element between the window rail and the recess of each of the external longitudinal supports. 279378/
