THE FIELD OF THE ART
[0001] The invention relates in the field of the art of aluminium framed door and window panels for buildings. Specifically, the invention proposes a system of aluminium framed door/window panels characterized by a perimetrical locking capacity, a novel configuration of reinforcing angular members employed in clamping together two sides of the frame or wing sides and provisions for air tightness and heat and sound proof capacity of such door or window panels.
THE BACKGROUND ART
[0002] Various systems of framed door and window panels are known in the prior art including among others door/window panels locked in a plurality of points. Consumer demand of burglarproof door/window panels has resulted in an increased demand for a plurality of locking points therein. EP 1219768, EP 845566 or EP 945580 all disclose door/window panel systems wherein locking together of the aluminium framed wing and frame members in a plurality of points is envisaged. However, these and other commercially available aluminium profile systems do not allow for an overall perimetrically locking device, whilst even in the confined number of locking points, locking security is rather restricted because of the rather shallow channel provided for in the wing member that does not allow reception of coupling rods of an adequate thickness. Moreover, such rather shallow channel of the wing member fails to provide an advantageously adjustable engagement of such coupling rods and instead leads to a requirement for a fixed riveting of the same.
[0003] Known systems of aluminium framed door/window panels also do not provide for the combination of such perimetrically locked panels with a sufficiently robust configuration of angular reinforcing connection members of frame sides providing for the reception of various commercially available hinge members for the suspension of wing panels from the fixed frame and further do not provide for the combination of such perimetrically locked panels provided with angular reinforcing connection members with means of an adequately air tight and heat/sound proof closure of the wing panels onto the fixed frame.
[0004] It is therefore an object of the present invention to advantageously overcome disadvantages and drawbacks of the prior art and provide a system of aluminium framed door/window panels with an optimally enhanced burglarproof capacity, such capacity being obtained by means of a channel in the wing member of adequate dimensions so as to receive perimetrically sequentially engaged linear and angular rods bearing a plurality of locking pins at a desired arrangement of a plurality of points, such channel also allowing employment of withdrawable and sequentially engaged linear and angular rod members provided with a toothed configuration in the connecting ends thereof.
[0005] Another object of the invention is to provide for an advantageous mushroom configuration of the locking pins employed in the aforementioned perimetrically locked panels of the invention, wherein each locking pin is provided with an enlarged mushroom shaped head and a circumferential recession in the cylindrical axial body underlying said enlarged mushroom shaped head so as to hook into engaging walls of the corresponding locking pin receiving member, an arrangement of such receiving members corresponding to the locking pins being fixedly mounted perimetrically onto the frame of the door/window panel assembly.
[0006] A further object of the invention is to propose embodiment of the aforementioned locking pins with the advantageous mushroom shaped head onto an arrangement of sequentially engaged linear and angular rods, mounted within the hollow sectioned perimeter of the wing member of the door/window panel assembly, said locking pins being received within a suitable plurality of receiving members fixedly mounted perimetrically around the frame member of the door/window panel assembly, wherein the perimetrically mounted plurality of locking pins may be alternatively set at a locked or unlocked condition by means of a single rotation of a rotatable handle mounted onto the wing member of the door/window panel assembly.
[0007] Another object of the invention is to disclose an optimally designed angular reinforcing connection member of the frame or wing sides of the door/window panel assembly, wherein such angular reinforcing connection member is provided in two alternative width dimensions, so that it may selectively be employed in door/window panel assemblies incorporating a heat insulating interface member or not, such angular reinforcing connection member being provided with an arrangement of openings adapted for the reception of suspension shafts of the side hinges of the wing members of the door/window panel assembly.
[0008] Another object of the invention is to propose alternative embodiments of the herein disclosed system of aluminium frame door/window panels with a perimetrical locking capacity as a compact system wherein each frame or wing member consists of a single aluminium profile or as a divided profile system wherein each frame or wing member consists of a pair of profiles being engaged by means of a heat insulating interface member thereby offering enhanced heat insulation properties.
[0009] Another object of the invention is to propose in association with the herein disclosed system of aluminium framed door/window panels, optimally designed rubber fittings for exterior and interior air tight sealing of the door/window panel assembly of the invention, as well as polyamide profiles adapted to operate as heat insulating interface members in a divided profile embodiment of the invention, wherein the combination of the abovementioned rubber fittings and polyamide profiles provide an optimally air tight and heat proof performance of the door/window panel assembly of the invention under all circumstances.
[0010] Another object of the invention is to disclose alternative profile sections and accessories in implementation of the scope of the invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0012] Figs. 1 and 2 present a perspective and a sectional view of a wing and frame profile members of the first embodiment of the invention for profiles of a compact structure, whereas Figs. 3 and 4 correspondingly show perspective and sectional views of a wing and frame profile members of the second embodiment of the invention for profiles divided in two parts with a heat insulating scope. In Figures 13 and 14 are shown perspective views of alternative embodiments of door/window panel assemblies of the invention wherein the profiles are of a divided heat insulating mode.
[0013] A frame profile member 1 and a wing profile member 2 is employed in each one of the alternative embodiments of the invention and in all various embodiments shown in Figs. 1-2, 3-4, 13, 14, the abovementioned frame profile member 1 and wing profile member 2 do exhibit a series of common characteristics.
[0014] Thus, wing profile member 2 under all circumstances comprises:
- The characteristic channel 4 wherein are slidably inserted all various parts of the perimetrical locking assembly of the invention.
- A pair of symmetrically opposite slots 20 adapted to receive pads 20a that provide a perimetrical supporting means of the glass panel 3.
- A linear leg extension member 11 and a rubber sealant receiving slot forming extension member 9 correspondingly at one and the other side of contact of the wing and frame profile members.
- An opening 7 overlying channel 4, wherein is inserted the angular reinforcing connection member 15' of the sides of the wing profile member 2.
- A channel 5 located opposite to channel 4 of the wing profile member 2, wherein are inserted the receiving members of the locking pins that project outwardly overlying channel 4.
- A linear leg extension member 12 and a rubber sealant receiving slot forming extension member 10 correspondingly at one and the other side of contact of the wing and frame profile members, wherein the linear leg extension member 12 further constitutes a side wall of the abovementioned channel 5.
- An opening 6 underlying channel 5, wherein is inserted the angular reinforcing connection member 15 of the sides of the frame profile member 1.
- A slot 14 adjacent to channel 5 adapted to receiving the centrally located rubber sealant 16a or 16b.
[0015] In accordance with the divided aluminium profile system embodiments illustratively shown in Figs. 3, 4 and 13, 14, the two discrete parts of the frame profile member 1 and correspondingly those of the wing profile member 2 are interconnected by means of the specially shaped reinforced polyamide profile members 32a and 32b shown in Fig. 7.
[0016] The polyamide profile 32a or 32b comprises a planar surface 33, the width of which corresponds to the distance separating the parts of the divided wing and frame profile members. The planar surface 33 extends into side protrusions 33a, 33b that are inserted within recessions being provided at symmetrically opposite ends of the parts of the divided wing and frame profile members.
[0017] The polyamide profile 32b additionally comprises a downwardly extending inclined leg member 33c and it is employed at the bottom of the interconnected parts of the wing profile member 2. The downwardly extending inclined leg member 33c abuts, as will be explained hereinafter, upon an extension of the central rubber sealant 16b employed in the divided profile embodiment of the invention.
[0018] The characteristic channel 4 of the wing profile member 2 has dimensions such as to receive the perimetrical locking mechanism comprising sequentially engaged linear and angular members with a toothed connection means being provided with projecting locking pins. In accordance with a preferred embodiment of the invention, always within certain tolerances, channel 4 has preferable dimensions of width 16.3 mm, depth 11.7 mm and axial distance of 9 mm from the opposing frame profile member.
[0019] The configuration of channel 4 allowing introduction within the same of linear and angular rod members being provided with the abovementioned toothed connection means result in the advantageous system of aluminium door/window panels of the invention that not only ensures substantially enhanced perimetrical locking security, but also offers precision and speed in the assembly process that might be performed even by relatively unskilled labour. Thus, as illustratively shown in Fig. 12, the engagement of an angular rod member 22 with a linear rod member 21 is performed through engagement of the male toothed end 22a of the angular rod member 22 with the female toothed end 21a of the linear rod member 21. The shallow channel of reception of rod members of the prior art does not allow introduction of the toothed engaged ends proposed in the present invention and instead have to undergo the time and skill consuming process of measuring distances and accurately cutting, perforating and eventually fixedly riveting connected rod members of the locking mechanism.
[0020] Fig. 8 shows an angular rod member 22 of the invention being provided with locking pins 24 at either side thereof, these locking pins being engaged when a locking movement is performed into corresponding receiving members 23 fixedly mounted onto channel 5 of the frame profile member 1. Fig. 10 shows an angular rod member 22 being provided with projecting locking pins 24 being inserted within channel 4 of the wing profile member 1 of the door/window panel assembly and adjacently shows a locking pin receiving member 23 being mounted onto channel 5 of a corresponding frame profile member 1. Fig. 9 shows another example of part of the perimetrical locking mechanism of the invention, wherein the rotatable handle 25 is engaged with a side extension mechanism 26 of linear rod member 21 for converting rotational motion of handle 25 into linear, reciprocating motion of the linear rod member 21. Accordingly, linear rod member 21 is provided with a projecting locking pin 24 that locks within the adjacently shown receiving member 23 located within channel 5 of the frame profile member 1.
[0021] Fig. 15 shows an overall plan of the sequentially engaged linear rod members 21 and angular rod members 22, both being provided with a desired number of locking pins 24 projecting outwards channel 4 of the wing profile member 2 and of the corresponding number of receiving members 23 located within channel 5 of the frame profile member 1. The overall plurality of locking pins 24 is set at a locked condition whereby all locking pins 24 are encaged within the corresponding receiving members 23 or at an unlocked condition wherein all locking pins 24 are released from corresponding receiving members 23, such locked or unlocked condition being performed by means of a simple clockwise or counterclockwise rotation respectively of the rotatable handle 25.
[0022] Another characteristic feature of the invention is the optimally designed angular reinforcing connection members 15 (Fig. 5a) and 15' (Fig. 5b) employed in the connection of frame and wing profile member sides respectively. Such angular reinforcing connection member is introduced within receiving channels 6 of the frame profile sides being brought into an orthogonal contact and correspondingly within channels 7 of the wing profile sides. Following introduction thereof into channels 6 or 7, the angular reinforcing connection members are pressed and fixedly mounted therein. Each angular reinforcing connection member 15 of the frame profile member 1 and 15' for the wing profile member 2 is provided in two alternative width dimensions, wherein the angular reinforcing connection member of the smaller width is adapted to be used in door/window panel assemblies incorporating a heat insulating interface member and the angular reinforcing connection member of the larger width is adapted to be used in door/window panel assemblies wherein the frame and wing profiles are of a compact structure. The configuration of the angular reinforcing connection member 15 of the frame profile member 1 is the same as that of the angular reinforcing connection member 15' of the wing profile member 2. However the angular reinforcing connection member 15 of the frame profile member is of increased thickness and is additionally provided with an arrangement of openings 15a adapted for the reception of suspension shafts of the side hinges 28 by means of which the wing profile members 1 are pivotally connected to the frame profile members 1 of the door/window panel assembly.
[0023] As shown in Fig. 11, each hinge 28 is provided with a pair of suspension shafts 29 which, during installation of the door/window panel assembly of the invention, are inserted and screwed within a corresponding pair of openings 15a of the reinforcing angular connection member 15. It is hereby noted that the elliptical configuration of openings 15a and their serial arrangement along the reinforcing angular connection member 15 are such as to ensure alternative employment of various types of commercially available hinges 28. Thanks to the extensive load receiving surface thereof, the reinforcing angular connection member 15 of the invention is capable of reliably withstanding the load of the wing panel suspended thereupon and thereby solving the problem of systems of the prior art wherein the wing panel is unreliably suspended directly from the relatively thin frame profile member.
[0024] Another characteristic feature of the invention is the ensuring of an optimum circumferential air tightness with the rubber sealants shown in Fig. 8. The circumferential rubber sealant 8 comprises a body 8c that fits within channel 9 of the wing profile member 2 at one side of the door/window panel assembly and at the other side thereof within channel 10 of the frame profile member 1. The body 8c of rubber sealant 8 fitted within channels 9, 10 extends into a pair of fins 8a, 8b that form an angle. When the wing panel closes onto the frame panel, the shorter fin 8b abuts on the side surface of either the linear leg extension member 11 of wing profile member 2 or on the side of the linear leg extension member 12 of the frame profile member 1. At the same time, the longer fin 8a correspondingly abuts on the top end of linear leg extension member 11 or 12. Such configuration of the circumferential rubber sealant 8 ensures an optimally reliable air tightness and contributes towards decreasing thermal losses, since it functions in a manner such as to increase the pressure of abutment of fin 8a on the top end of linear leg extension member 11 or 12 as wind tends to press upon the shorter fin 8b increasing abutment thereof with the side surface of linear leg extension member 11 or 12.
[0025] Another characterizing feature of the invention is the employment of the centrally located rubber sealant that alternatively takes the form 16a or 16b that is respectively being used with the aluminium framed door/window panels of the compact or the divided type. The central rubber sealant comprises a body 30 that is of a planar form (16b) or elongated form (16a) correspondingly in the alternative versions of divided and compact profile system of the invention. In either case the body 30 of the central rubber sealant extends into side slots 30a, 30b that slidably abut into nerves on either side of channel 14 of the frame profile member 1. The upwardly extending body 30 of the central rubber sealant 16a, 16b terminates at a downwardly bent fin end 31, which abuts onto a downwardly extending inclined surface 13 of the wing profile member 2 in a compact aluminium profile series and onto the downwardly extending inclined leg member 33c of the polyamide profile 32b employed in a divided aluminium profile series.
[0026] A characterizing feature of the invention is the mushroom configuration of the locking pins 24 being provided along the aforementioned sequentially engaged linear rod members 21 and angular rod members 22. Each locking pin is provided with an enlarged mushroom shaped head and a circumferential recession in the cylindrical axial body underlying the enlarged mushroom shaped head so as to hook into engaging walls of the corresponding locking pin receiving member 23 of the arrangement of such receiving members 23 corresponding to the locking pins being fixedly mounted perimetrically onto the frame of the door/window panel assembly.
[0027] It must herein be noted that the description of the invention was made by reference to non-confining illustrative examples. Thus any change or amendment relating to the dimensions, design characteristics or applications of the invented object is to be considered part of the scope and the aims of the appended claims.
a channel (4) of the wing profile member (2) having dimensions such as to receive a perimetrical locking mechanism comprising sequentially engaged linear rod members (21) and angular rod members (22), said linear rod members (21) and angular rod members (22) being provided with a plurality of projecting locking pins (24) and wherein a rotatable handle (25) is engaged with a side extension mechanism (26) of a linear rod member (21) for converting rotational motion of said handle (25) into linear, reciprocating motion of the linear rod member (21) and henceforth of the overall assembly of sequentially engaged linear rod members (21) and angular rod members (22), so as to effect either a simultaneous engagement of the overall plurality of said locking pins (24) within corresponding receiving members (23) located within a channel (5) of the frame profile member (1), thereby setting said aluminium door/window panel assembly at a locked condition or a simultaneous release of all locking pins (24) from corresponding receiving members (23), thereby setting said aluminium door/window panel assembly at an unlocked condition;
