Patents Act 1990 INNOVATION PATENT FOR THE INVENTION ENTITLED "IMPROVEMENTS IN MEANS FOR JOINING, AND CLOSURE MEANS INCORPORATING SUCH" This invention is described in the following statement:- 09/03/04jf 3940 spc, l IMPROVEMENTS IN MEANS FOR JOINING, AND CLOSURE MEANS INCORPORATING SUCH Field of the Invention The present invention relates to a means for receiving, and preferably releasably retaining, at least one end of an elongate member, whereby to allow for such member to be releasably and relatively movably associated with one or more other elongate members of a similar type.

In actual fact, however, the method and means in accordance with the present invention can be used in any context or application wherein a preferably removable, but alternatively fixed, barrier, be it of transparent material or otherwise, is to be provided across a given space, whether such space be a doorway, a window or indeed any other gap within a building or the like structure. The method and means in accordance with the invention is particularly suited for use in any context wherein adjacent or contiguous, preferably elongate, elements are to be loosely joined together, so as to allow, for example, for limited pivotal or rotational movement therebetween.

The present invention relates, in general terms, to an improved method and means for receiving, and releasably retaining within a given structure, an elongate member. More particularly the invention relates to improvements in means for the releasable interconnection of a plurality of elements, in particular adjacently-disposed or juxtaposed (end to relative end) elongate elements. In an especially preferred embodiment, the invention relates to a method and means which allows for the ready and efficient construction of a door or closure means of the sliding or roller type, of the type made up of a plurality of elongate sections (or slats) of any given size and shape extending laterally and/or longitudinally of a door frame or jamb within a given structure, such sections (or slats) being constructed from a suitable transparent or translucent material and being intended to be releasably affixed to the said door frame or jamb, whereby to provide a removable barrier therefor.

09/03/04jf13940 spc,2 The invention further relates to a means which allows for releasably and relatively movable interconnection of a plurality of elongate members in horizontally extending and/or vertically extending arrays.

The invention also relates to an improved closure means, preferably of the lifting, sliding and/or rolling type, which includes horizontally and/or vertically extending arrays of elongate elements of sufficient number to constitute a retractable closure means for any given area/locale in a building or the like structure, whether such structure is for domestic and/or commercial purposes.

In an especially preferred embodiment the invention relates to a method and means which allows for the ready and efficient construction of a door or the like closure means, of the sliding or rolling type, which is made up from a plurality of elongate sections (or slats) of any given size and shape and adapted to extend laterally and/or longitudinally of a door frame or jamb within a given structure, such sections (or slats) being constructed from a suitable transparent or translucent material (dependent upon intended usage) and being intended to be releasably associated with the said door frame or jamb, whereby to provide a removable, retractable barrier therefor. It should be realised, however, that a closure means in accordance with the present invention could be constructed to suit, or be available for use in, the formation of a barrier against unwanted ingress through any given portal or aperture in a building or the like structure, as for example a window, skylight, door, garage, etc. In actual fact the method and means in accordance with the present invention can be used in any context or application wherein a preferably removable, but alternatively fixed, barrier, be it of transparent material or otherwise, is to be provided for a given space, whether such space be a doorway, a window or indeed any other gap within a building or the like structure. The method and means in accordance with the invention is particularly suited for use in any context wherein adjacent or contiguous, preferably elongate, elements are to be loosely joined together, so as to allow, for example, for limited pivotal or rotational movement therebetween.

09/03/04jl f13940 spc,3 -4- Background of the Invention These days sliding, lifting and/or rolling or shutter-type doors are commonly employed for purposes of closing off, against unwanted access, areas in a variety of different contexts, nowhere more so than in retail outlets and the like. Such doors are also used for garages (domestic and/or otherwise), as well as in other contexts. Throughout the ensuing description reference will be made to an especially preferred embodiment of, or usage for, the arrangements in accordance with the present invention, namely in the construction and operation of a door of the aforementioned sliding, lifting or rolling type (hereinafter referred to simply as "a roller door"). It should be understood, however, that the invention is not to be considered to be restricted to any preferred embodiment or embodiments described hereinafter.

There are, in principle, four main types of such roller doors. These may best be described as: a roll-up door, wherein it is adapted to be retractable or expansible in a relatively vertical direction with a given space; (ii) a side-folding or concertina door, intended to be retractable and expansible in a substantially horizontal direction relative to a given space; (iii) a fold-up type door, again of the concertina type, intended to be folded up, in a substantially vertically direction, to be stored (when not expanded) parallel to a roof or ceiling of a given space; and (iv) a sectional door.

The arrangements described herein are adapted to be usable, selectively, with all these types of doors. Which of these types of roller door is usable in a given situation or locale is dependent upon space available, as well as the actual layout of the space or area which needs to be enclosed.

A first type of such roller door is best suited for, in fact intended or designed for, usage in a locale wherein there is sufficient additional room or space above the upper extremity of the relevant portal to allow for the door to be rolled up in a substantially vertical direction without 09/03/04j f13940 spc,4 the rolled-up door in any way encroaching on the available door space. A second type is intended for use in a situation or locale wherein, because of dimensional or other constraints, it becomes necessary for the door to be openable or retractable in a sideways or horizontal direction.

The arrangements in accordance with the present invention, as described and illustrated hereinafter in more detail, are specifically and individually designed for use in both of the aforementioned types of roller door, whether vertically or horizontally retractable.

The Prior Art With the prior art arrangements, roller doors of this general type were made up of juxtaposed arrays of elongate members intended to span a given opening, as for example a doorway or the like. In most contexts, and due to constructional constraints, a vertically extending array only may be involved, made up from a plurality of elongate elements of a suitable material, each of a length which in effect spans the area or opening to be closed off. Alternatively, however, if circumstances are right and dependent upon the overall dimensions of the space to be enclosed or closed off, both horizontally and vertically extending arrays of smaller-sized panels may be involved. In any case, the problem is to allow for connection of free ends and/or edges of adjacent elongate elements or panels to one another, and/or to a means which allows for rolling movement thereof whether vertically or horizontally as required, of the overall door structure.

With the prior art arrangements the methods and means employed for releasably associating an elongate member or element of any suitable material, as for example glass, acrylic, polycarbonate or the like, relative to a given framework, or for that matter to a similar elongate element, relied for their effectiveness on the use of ancillary material, in the form of one or more wedges of rubber or the like material, as well as preferably a suitable adhesive such as, for example, a mastic material. Such wedges and/or adhesive were required in order to protect against the potential for an elongate member to inadvertently become separated from the framework, or from the or an adjacent elongate member, due to the effects of expansion and/or 09/03/04j f13940 -6contraction of the material making up such members, as could come about due to the effects of heating and/or cooling, or during actual movement of such members. In that regard it must be realised that, with material of the type presently in use for the construction of such elongate elements or members, the actual physical extent of such expansion and/or contraction can be quite significant. The consequences of such unwanted separation of elongate members from the framework and/or adjacent members, in terms of loss of integrity and hence security, should be self-evident.

Further with the prior art arrangements problems have been encountered in attempts to use elongate members constructed from glass, transparent or otherwise. Prior art efforts have been thwarted by an inability to have such glass members securely held without undue rattling during movement and with an unacceptable possibility of separation, and hence breakage. In addition, with the prior art arrangements there has been a tendency, during rolling movement of the elongate members, to have at least some degree of surface-to-surface contact therebetween, which in turn can give rise to unsightly and unseemly scratches on the panels or elongate members themselves.

The arrangement in accordance with the present invention seeks to overcome the problems and disadvantages associated with the prior art by providing a method and means for affixing an elongate member, slat or section, constructed of glass or other suitable material, within or across a given space (as for example a doorway or door jamb) or, in the alternative, for joining together adjacent or contiguous sections or slats of like material in such a way as to minimise, if not remove altogether, the likelihood of unwanted separation therebetween, even during movement thereof.

The present invention also seeks to provide a door or closure means, of the roller type, which is capable of rolling movement, not only in a straight line in a vertical or horizontal direction, but even along a curved path or track.

In accordance with one aspect of the present invention there is provided a means for receiving, and releasably retaining, at least one elongate element, said retaining means being in the form 09/03/04jfI 3940 spc,6 -7of a shaped member having, extending inwardly from at least one side thereof, a slot recess or the like discontinuity of a shape which is substantially complementary to that of said at least one element elongate to be releasably retained therein, wherein one of either said at least one element elongate or said slot, recess or the like discontinuity of said shaped member has formed therein at least one groove, slot, recess or the like, and wherein the other of said at least one elongate member and/or said slot, recess or the like discontinuity of said shaped member has formed therein at least one lug or projection extending from a surface thereof, the arrangement being such that, in use, said at least one lug or projection is adapted to be disposed within and relative to said at least one slot, groove, recess or the like, whereby to releasably locate said at least one elongate element relative to said shaped member.

In accordance with another aspect of the invention there is provided a means for interconnecting, releasably or fixedly, two elongate elements, said means being in the form of a shaped member having opposed slots, recesses or the like discontinuities therein of a shape and size substantially complementary to that of said elongate elements, wherein at least one of either each said elongate elements and an associated slot, recess or the like discontinuity of said shaped member has formed therein at least one slot, groove or the like, and wherein at least the other of each of said elongate elements and associated slot, recess or the like discontinuity of said shaped member has formed therein a lug or projection extending from a surface thereof, the arrangement being such that, in use, said lug or projection is disposed within said slot, groove or the like whereby to releasably locate said elongate elements relative to said shaped member.

In accordance with a further aspect of the present invention there is provided a means for connecting, releasably or fixedly, adjacent ends of two elongate elements, wherein each said elongate elements has at least one slot, groove or the like discontinuity formed therein, said at least one slot, groove or the like discontinuity being located at or in the vicinity of at least one end of each said elongate elements, said connecting means including a member, of a substantially complementary shape to said end of said elongate member, said connecting means including at least one projection adapted, in use, to extend into said slot, groove or the like discontinuity of the associated elongate element.

09/03/04j f13940 spc,7 In accordance with a further aspect of the present invention there is provided a connecting means adapted, in use, to be disposed on or in relation to an elongate member, as for example a slat or the like of a rolling or sliding type door, said connecting means being adapted to be, disposed around an end portion of said elongate member and having at least one projection directed inwardly thereof, said at least one projection being adapted, in use, to extend into a substantially complementary shaped groove formed in said end portion of said elongate member, whereby to retainsaid connecting means in place relative to said elongate member.

In accordance with yet another aspect of the invention there is provided a closure means of the roller or sliding door type, said closure means including: a plurality of elongate members or elements, arranged in arrays vertically and/or horizontally relative to one another; means interposed between juxtaposed pairs of said elongate elements to allow for interconnection thereof, said interconnection means being of the type defined in any one of claims 1 to 4; and means allowing for connection of opposed end ones of said longitudinal arrays of elongate elements to opposed end elements of said closure means.

Description of Preferred Embodiments With particular regard firstly to the arrangement shown in FIG. 1, there is illustrated therein one preferred means for receiving and releasably retaining a sheet or elongate member 1, in such a way as to allow that member to be incorporated, for example, in a roller door assembly.

The elongate member 1 is in the form of an elongate strip of any given dimensions, constructed of a suitable material, be it glass, acrylic, polycarbonate, aluminium or any other material. Such a means may be necessary, for example, in any situation wherein there is a need to provide a barrier, be it transparent or translucent, unbroken or broken, across a given space in any given structure, as for example a window, a door or the like. The means for 09/03/04jf1 3940 spc. -11retaining includes an extrusion, generally designated 2, which may be formed from any suitable material as for example a metal such aluminium, or a plastics material. In that regard one or more of such extrusions 2 may then be associated with a door of the roller type adapted to span a doorjamb, a window frame, or some other structural element serving to define and enclose the given space. In the embodiment illustrated the sheet of material, generally designated 1, has formed therein, at or in the vicinity of the or each end thereof which is adapted, in use, to be slidably located within the extrusion 2, a slot, groove or the like 3, such slot, groove or the like 3 preferably extending across the width of the sheet 1, from one edge to the other. In an especially preferred embodiment the extrusion 2 has formed therein, at or in the vicinity of an edge portion or free end thereof, an aperture or slot 4, preferably extending inwardly from the free end thereof and of a substantially complementary shape and size to the sheet or panel 1, thereby to allow for a substantial pressure-type fit when the sheet or panel 1 is located within the extrusion 2, as for example by sliding. The extrusion 2, adapted in use to be disposed around a free edge of the sheet 1, has formed therein, and internally of the slot 4 thereof at or in the vicinity of at least one end thereof and at least one side thereof, a lug or projection 5 which is adapted, in use, to extend into the slot, groove or the like 3 provided in the sheet 1. Interaction between slot, groove or the like 3 and projection serves to assist in maintenance of relative interconnection between sheet 1 and extrusion 2.

In an especially preferred embodiment, however, and as shown in the drawings, the extrusion 2 may also have formed therein, and extending at least partially along the length of the slot 4 thereof, a series of serrations 6. In use a wedge 7, preferably also having a series of serrations formed thereon, may be disposed within the slot 4 of the extrusion 2 and be in contact, again in a pressure-type fit, with a side of the elongate member, being that side remote from or opposed to the slot 3 thereof 1. Such wedge 7 could be constructed of any suitable material, as for example a flexible material such as rubber or the like, or even from a metal such as aluminium. Preferably the wedge will be formed by extrusion. It should be realised, however, that neither the material of construction nor the method of formation of that wedge 7 is of the essence of the invention.

09/03/04jfl13940 spc, I 1 -12- The arrangement is such that interaction between the groove 3 of the elongate member 1 and the projection 5 of the extrusion 2, as well as the wedge 7 and its serrations with the corresponding adjacent portion of the extrusion 2, affords an improved and sustainable connection between elongate member 1 and extrusion 2. In use, no adhesive need be required in order to maintain the desired connection between the elongate member 1 and the extrusion 2, even in a situation wherein the elongate member 1 undergoes significant expansion and/or contraction (due to changes in temperature). This is in marked contrast to the known arrangements, wherein a suitable adhesive or the like is invariably needed to ensure proper connection and the maintenance thereof.

The embodiment of FIG. 1 is especially suited to use in the situation wherein a single elongate sheet or panel, as for example a side element of a sliding or roller type door, is intended to be affixed, in any suitable manner, within a channel or the like member extending along the height dimension of that door and/or the associated jamb and to be slidably movable therealong, whereby to allow for selective opening and/or closing of the overall door.

Turning now to FIG. 2 there is shown therein an alternative embodiment to the arrangement of FIG. 1, wherein two wedges 7 of the aforementioned type are employed. Such may be suitable for use in a situation wherein there exists a significant difference between the width dimension of the sheet 1 and the size of the slot 4 formed in the extrusion 2.

With reference now to FIG. 3, there is shown therein a means in accordance with the present invention for joining together, releasably, juxtaposed ends of two adjacently disposed elongate members 1. The extrusion 20 employed for this purpose has opposed slots 4 formed therein, each having a projection 5 formed therein, as well as preferably an array of serrations 6. An arrangement such as this could also be employed to form a panel or window, or in fact could be used in any context wherein two adjacent sheets are to be interconnected, for whatever constructional reason. Such an embodiment is best employed, for example, in any situation wherein a door of the general type under consideration includes a longitudinally extending array of elongate members, wherein the opposed free ends of adjacent members need to be releasably interconnected one to another.

09/03/04jfl 3940 spc, 12 13- FIGS. 4a and 4b show side views of another preferred embodiment of an arrangement in accordance with the present invention, particularly suited for connecting together a plurality elongate members or sheets 1 intended for use in a door of the sliding or rolling type, in such a way as to allow for the creation of an elongate array of such members and also to allow for a degree of relative movement between such interconnected members. There is provided an extrusion 40, preferably formed of aluminium or the like suitable material, preferably of a shape substantially similar to that of the sheet or panel 1 to be slidingly associated therewith.

Such extrusion 40, in like manner to the arrangements of FIGS. 1 to 3, has a shaped slot 4 extending at least part-way along the length dimension thereof, such slot 4 having at least one projection 5 extending inwardly thereof. At the other free end of the extrusion 40 there is provided or formed a hook-like extension, generally designated 43. The slot 4 preferably includes, on at least that side thereof remote from the projection 5, a series of internal serrations 6. As was the case with the embodiments of FIGS. 1 to 3 a wedge 7, preferably having a series of serrations thereon, may be used to assist in fixing of the sheet or panel 1 within the slot 4 of the extrusion 40. The arrangement is such that in use a sheet or panel 1, of the type previously described, having a slot, groove or the like 3 formed therein at or in the vicinity of at least one end thereof, can be located within the extrusion 40 as by sliding.

Interaction between projection 5 of extrusion 40 and slot, groove or the like 3 of the sheet 1 serves to retain the sheet or panel 1 within that extrusion 40, substantially proof against unwanted or inadvertent separation therebetween. Preferably the end of the sheet or panel 1 may be bevelled (not shown). It should be realised that such an embodiment can function without the need for any additional fixing means, as for example a wedge or adhesive means of the type employed with the earlier described embodiments.

The hook-like end extension 43 of the extrusion 40, associated with that end thereof removed from the slot 4, allows for construction of a roller-type door incorporating a plurality of extrusions 40 and sheets 1 of glass or the like material, arranged in horizontally and/or vertically extending arrays, in a manner to be described hereinafter in more detail.

09/03/04jf13940 spc,13 -14- Turning now to FIGS. 5a and 5b, there is shown therein a method and means in accordance with the present invention which allows for the releasable association/interconnection of adjacent sheets 1 of elongate (barrier) material of the aforementioned general type in such a way as to allow for creation of an array of thus interconnected sheets, thereby to allow ultimately for creation of a barrier across any extensive area. The arrangement is such that, in a manner to be explained hereinafter in more detail, adjacent, juxtaposed sheets 1 are capable of relative pivotal movement therebetween. Such allows for the creation of doors or closures, of the sliding or roller type, which can follow an other than straight, or in other words a curved, path.

The preferred embodiment as illustrated in FIGS. 5a and 5b includes a hinge member or post, generally designated 50, which is preferably in the form of a shaped extrusion of a suitable material such as aluminium and of a length or height dimension which can be varied dependent on the size of the overall door or closure means required to create a desired barrier across a given space or area. One of such hinge members 50 will be disposed between adjacent free ends of adjacent/juxtaposed sheets or panels 1 of an overall door or closure. In that situation wherein a roller door assembly is made up from a plurality of vertically juxtaposed, horizontally extending arrays of interconnected panels 1, each hinge member 50 disposed between adjacent pairs of panels 1, will extend over substantially the entire height dimension of the door assembly itself. The respective horizontal rows/arrays of interconnected panels can then be disposed, one above the other, over the length/height of the hinge member 50, whereby to create the overall roller door assembly.

The hinge member 50 includes opposed formations 51 of a shape and size substantially complementary to the hook-like projections or formations 43 of the extrusions 40 as shown, for example, in FIGS. 4a and 4b. The hinge member 50 includes, at opposed ends thereof, substantially circular apertures or formations 52 and 53 extending along the entire length thereof, such to serve a purpose to be described in more detail later in this specification. The arrangement is such that, in use and as shown in FIGS. 5a and 5b, the hinge member 50 is adapted to receive and releasably retain, in a sliding type connection, the hook-like projections 43 of the extrusions 40 which are retaining adjacent panels 1. The sizing and shape of the 09/03/04jfl3940 spc, 14 formations 51 of hinge member 50, and the projections 43 of extrusion 40, is such as to allow for adjacent panels 1, in use, to be disposed at a variety of positions relative to one another, from that shown in FIG. 5a which corresponds to the expanded condition or state of the overall door or closure, to that shown in FIG. 5b which corresponds to the retracted condition or state for the door or closure, and in fact at any intermediate position or angular disposition therebetween. This affords increased flexibility of use or opportunities for use, as for example allowing for the formation of curved or other-than-straight closures or doors of the roller type.

With reference now to FIGS. 6a and 6b, there is shown therein an especially preferred means, to be employed in a sliding or roller type door of the type under consideration, to be employed for releasably and pivotably connecting adjacent panels. The arrangement includes a hinge member 50, of the general type shown in FIGS. 5a and 5b, having extrusions 40 associated therewith as shown. At each end of the hinge member 50 a washer 60 or spacer is adapted to be fixedly, yet removably, associated therewith, per medium of a threaded member 61.

Doors of the general type under consideration, whether designed to open and/or close vertically, horizontally or at any other angle, generally include an assembly made up of a plurality of interconnected, and relatively movable, panels or sections which are adapted, in use, to be continuously and progressively movable between respective open and closed positions, whilst supported for actual movement along a track or tracks (preferably with a separate track for two opposed free edges thereof). In accordance with existing practices such doors typically have associated therewith some form of counterbalancing system, an opener mechanism (preferably key-actuated) and other structural support members. The present applicant's arrangement includes such other components, but they do not form part of the invention and, for purposes of clarity, these components are not illustrated. Since such components are well known, there should be no need to refer thereto in any detail for purposes of understanding the present invention.

With reference now to FIGS. 7a, 7b and 7c, such drawings show portion of a sliding door or closure means in accordance with the present invention in respective fully extended or close condition, partially extended condition and retracted or storage condition. In accordance with 09/03/04jfl 3940 spc.l -16known and standard practices a door or closure means, formed from any suitable number of individual sheets or panels 1, is disposed so as to be movable along a track 70 of any known type. In the embodiment illustrated the track 70 is shown to be angular or curved in shape.

As shown in FIGS. 7a to 7c a door in accordance with the invention is comprised of a plurality of individual panels or sections 1. Indeed, and dependent upon the dimensions of the barrier needed, a suitable number of mutually interconnected, relatively pivotably movable individual panels 1 may be employed. The door may be formed in a number of different ways. In one embodiment it may be made up from a plurality of full-height panels 1 in other words of a height dimension corresponding to that of the space to be closed off arranged in a horizontally extending array. In an alternative embodiment a plurality of smaller panels 1, arranged in mutually interconnected horizontally and vertically extending arrays, may be employed.

At the upper and lower extremities of a door thus formed there may be provided, associated with each or selected ones of said panels 1, a frame member 71 adapted to afford additional strength to the overall structure, and further including located thereon means 72, of any suitable type, which allow for movement of the panels 1 along an associated track 70, again of any given type. In the preferred embodiment illustrated such may be in the form of castors, rollers or the like 72 rotatably mounted on a spindle or the like shaft means 73 attached to each frame member 71.

Adjacent panels 1 in any horizontal array are connected for hinged movement relative to each other by joints or hinge members 50 of the general type described earlier in this specification and illustrated, for example, in FIGS. 5a and 5b. The front face of each panel 1, if of a translucent (opaque) material, may have indicia or design patterns formed thereon, in various manners, as for example by the use of raised mullions, moulded decorative front panel surfaces or other markings. Such does not constitute part of the invention.

With regard now to Fig. 8, there is shown therein a door, of the rolling or sliding type, and more particularly of the type intended to be retractable and expansible in a sideways or 09/03/04jfl 3940 spc, 16 -17relatively horizontal direction, made up of a plurality of juxtaposed elongate members 1 of any suitable material interconnected using means of the type shown, for example, in Figs. 6 and/or 7, and having one end of a first of said elongate members 1 associated with a joining means 2 of the type shown in Figs. 1 and 2, in turn to be associated with a doorjamb or the like within which the rolling or sliding type door is to be disposed.

Turning now to FIGS. 9 to 11 there is shown therein an arrangement in accordance with the present invention for the creation of a door of the roller or shutter type, wherein the various shutters or panels making up such a door are comprised principally of glass or, in the alternative a plastics material, transparent or translucent as required. In FIG. 9 there are shown five glass panels 100, adapted to be connected end-to-end in longitudinal arrays, with each array being separated by an intermediate panel 101 of another suitable material, as for example aluminium, or perhaps even a plastics material. In practice, however, any number of such glass panels 100 and associated dividers or intermediate panels 101 may be joined endto-end, both laterally and/or vertically, dependent upon the length of each individual panel and the width of the space to be occupied by the overall door. Furthermore, a door of the roller or shutter type may be created or formed by interconnecting the appropriate number of laterally extending arrays of individual panels, utilising the joining means or extrusions referred to earlier, in the relevant combinations.

Interposed between adjacent panels, and extending along substantially the entire height dimension of the overall door, are hinge members or posts 50 of the type shown in FIGS. and 5b. Releasably located, as by sliding, within opposed formations 51 of each hinge member 50 will be retaining means 40 of the general type shown in FIGS. 4a and 4b, such being in the form of extrusions, preferably of a metal such as aluminium, and of a length substantially the same as the height of each hinge member 50. The interacting hook-like formations 43 and 51 of retaining means 40 and hinge member 50 serve to provide the requisite pivotably movable connection therebetween. This capability of relative pivotable movement allows for: firstly, gilding of the overall door in an efficient manner and, alternatively, allows doors of this type to be associated with curved tracks, thereby to adopt an overall curved shaped where extended.

09/03/04jf13940 spc. 17 -18- Located within either or both of the circular formations 52 and 53 of each hinge member may be one or more retractable rods 103, such being selectively movable within said formations 52 and 53 between respective projecting and retracted conditions. When in the projecting condition, as shown in FIG. 9, the free end of each rod will extend outwardly from the associated free end of said hinge member 50, to be located within a complementary shaped aperture provided in the associated doorjamb. In such a way the overall door can be locked in position, substantially proof against unwanted sliding or rolling movement, until such time as each rose in withdrawn to its retracted position, when housed entirely within the associated hinge member 50. In the preferred embodiment illustrated, see for example FIG. 9, each rod will have a shaped handle member 104 associated therewith (releasably or fixedly).

Movement of the locking rods 103 is achieved by selective upward or downward movement of the handle member 104 along a slot 105 provided in the associated hinge member With particular regard now to FIG. 10 there is shown therein an aluminium panel 101 of FIG.

the type shown in FIG. 9, having associated therewith and extending along opposed sides thereof extrusions of the type as shown in FIG. 3, with a wedging system 6, 7 as previously described assisting in maintaining the desired interconnection between panel 101 and extrusion 20. Connected to the other side of each extrusion 20, whereby to allow for creation of an array of interconnected glass panels 100 and aluminium panels 101, is a glass panel 100, with or without the interposition of a wedge system 6,7.

FIGS. 11 and 12 then shows the arrangements employed in accordance with the invention for interconnecting adjacent longitudinally aligned panels 100, whereby to create a laterally extending overall door structure comprised of a plurality of glass panels 100, aluminium panels 101 and the appropriate extrusions 40 for achieving interconnection of adjacent, spaced apart panels 100 whereby to allow for a pivotable connection therebetween, hence to allow for rolling of the overall door to suit differing use requirements.

FIG. 13 shows an end-on view of an especially preferred embodiment of the arrangement of the present invention, particularly suited for connecting together sheets 1 intended for use in a 09/03/04jf1 3940 spc, 18 -19door of the sliding or rolling type. There is provided an extrusion 140, preferably formed of aluminium or the like suitable material, of a substantially circular shape in cross-section and preferably of a length similar to that of the sheet or panel 1 to be slidingly associated therewith. Such extrusion 140 has a shaped slot 141 extending along the length dimension thereof, such slot 141 having at least one projection 142 extending inwardly thereof. The arrangement is such that, in use, a sheet or panel 1, of the type previously described, having a slot, groove or the like 3 formed therein at or in the vicinity of at least one end thereof, can be located within the extrusion 140 as by sliding. Interaction between projection 142 of extrusion 140 and slot, groove or the like 3 of the sheet 1 serves to retain the sheet or panel 1 within that extrusion 140, substantially proof against unwanted or inadvertent separation therebetween.

In the embodiment shown, preferably the ends of the sheet or panel 1 will be bevelled as shown as at 143. This embodiment can function without need for any additional fixing means, as for example a wedge or adhesive means of the type employed with the earlier described embodiments.

FIG. 14 shows yet another alternative arrangement in accordance with the present invention, in effect a combination of the embodiments/features of FIGS. 1 and 13. There is shown therein an element 150, again in the form of an extrusion, having projecting from one side thereof an arrangement 151 of a similar configuration to that shown in Figs. 1 to 3 and, displaced therefrom as shown, a semi-circular (substantially), hollow portion 152 which is adapted to have located therein a connecting means 140 of the type shown in Fig. 4. The hollow portion 152 has an opening 153 provided therein, through which in use a sheet of glass or the like elongate member 1 can extend.

The arrangement 151 has, in like manner to those shown in Figs. 1 to 3, a slot 4 and associated inwardly directed projection 5, adapted in use to be co-operable with a slot, groove or the like 3 formed in a sheet or elongate member 1 to be located therewithin. Once again one or more wedges 7, of the type referred to earlier, may be employed to ensure a pressure-type fit.

At the other side of the element 150, housed within a preferably substantially semi-circular section thereof, is an extrusion 140 of the type shown in FIG. 13, such being adapted, in use, 09/03/04jf13940 spc, 19 to receive and releasably retain a free end of a further elongate element 1. The arrangement is such that the extrusion 140, with associated elongate member 1, may be selectively movable relative to the element 150. Such an arrangement is especially suited for use in a door of the rolling or sliding type, including an array of elongate members 1 to be joined end-to-end.

Such an embodiment may be employed, for example, to connect together two elongate elements disposed, relatively speaking, one above the other. In other words, therefore, such an extrusion is usable for connecting together juxtaposed members of separate, spaced apart horizontal arrays.

Turning now to FIGS. 15 and 16, there is shown therein a possible variant of the arrangement of FIG. 14. A connecting means 160, in the form of a shaped extrusion of any desired length has, at one side thereof, an arrangement 161, similar to that shown as 151 in FIG. 14, for receiving and releasably retaining therein an elongate member, as described with regard to Figs. 1 to 3. As with the embodiment of Fig. 14 the connecting means 160 has, at the other side thereof, a substantially semi-circular portion 162 having associated therewith, and incorporated therein, a hook-like configuration or component 163 adapted, in use, to cooperate with a complementary-shaped similar configuration 171 formed at one end of a further extrusion or connecting means 170. In use, means 170 may be releasably connected to connecting means 160, by means of the respective mating hook-like configurations 163, 171.

The extrusion 170, in like manner to the arrangements shown in FIGS. 1 to 3, includes at the end thereof remote from the hook-shaped component 171 a slot 4 having a projection or lug depending downwardly (relatively) from one surface thereof, and a series of serrations 6 formed in the opposed surface thereof. As with the embodiments of FIGS. 1 to 3, a sheet or panel (elongate) of any suitable material may be disposed within the slot 4, with or without interposition of any form of wedge, with there being no need for the use of mastic or the like adhesive means to maintain connection.

With regard now to Fig. 17, there is shown therein a door, of the rolling or sliding type,, and in particular of the type intended to be retractable and expansible in a substantially relatively vertical direction, made up of a plurality of juxtaposed elongate members 1 of any suitable 09/03/04j f13940 -21 material interconnected using means of the type shown, for example, in Figs. 14, 15 and 16, and having one end of a first of said elongate members 1 associated with a joining means 2 of the type shown in Figs. 1 and 2, in turn to be associated with a doorjamb or the like within which the rolling or sliding type door is to be disposed.

Turning now to FIGS. 18 to 20, there is shown therein an arrangement in accordance with the present invention for the creation of a door of the roller or shutter type, wherein the various shutters or panels making up such a door are comprised principally of glass. In the drawings there are shown two elongate glass panels 200, adapted to be connected end-to-end. In practice any number of such glass panels may be joined end-to-end, dependent upon the length of each individual panel 1 and the width of the space to be occupied by the overall door.

Furthermore, a door of the roller or shutter type may be created or formed by interconnecting the appropriate number of laterally extending arrays of individual panels, utilising the joining means or extrusions referred to earlier, in the relevant combinations.

With particular regard to the especially preferred embodiment illustrated, however, two panels 200 preferably of glass are shown, each having located thereon and associated therewith, along the respective top and bottom sides or edges, extrusions of a suitable material, of the general type referred to earlier in this specification. More especially, the extrusion disposed on the top edge may be of the configuration 160 as shown, for example, in FIGS. 15 and 16, whilst that disposed on the bottom edge may be of the general type as shown at 170 in that same FIGS. 15 and 16. By using such means, adjacent rows of panels 1 can be interconnected whereby to allow for formation of interconnected lateral and longitudinal arrays of panels, thereby to form a roller or sliding door of the size and shape needed to occupy a given space.

At each end of each panel 200 there is provided an intermediate or fill panel, generally designated 201. Such can be formed from any suitable material, as for example a lightweight metal such as aluminium, or perhaps a suitable acrylic material. The fill panels 201 are in the form of extrusions having the shape in cross-section as shown, for example, in FIG. 3. The arrangement is such that, with a fill panel 201 of this general configuration, two adjacent glass panels 200 can be retained thereby, preferably with the interposition of at least one wedge 7 of 09/03/04jfl 3940 spc,21 -22the type also shown in FIG. 3. In an especially preferred embodiment (not shown) a strip of PVC protective material may be used, attached to the outside edge of the glass panels 200, instead of such a wedge 7.

With particular regard now to FIG. 19 there is shown therein an aluminium panel 201 of the type shown in FIG. 18, having associated therewith and extending along opposed sides thereof extrusions 20 of the type as shown in FIG. 3, with a wedging system 6, 7 as previously described assisting in maintaining the desired interconnection between panel 201 and extrusion 20. Connected to the other side of each extrusion 20, whereby to allow for creation of a longitudinal array of interconnected glass panels 200 and aluminium panels 201, is a glass panel 200, with or without the interposition of a wedge or the like.

FIG. 20 then shows the arrangements employed in accordance with the invention for interconnecting adjacent longitudinally aligned panels, whereby to create a laterally extending overall door structure comprised of a plurality of glass panels 200, aluminium panels 201 and the appropriate extrusions for achieving interconnection of adjacent, vertically spaced apart panels whereby to allow for a pivotable connection therebetween, hence to allow for rolling up or down of the overall door to suit differing use requirements.

As shown, attached to one side or top edge of a glass panel 1 is an extrusion or connecting means of the type shown, for example, at 160 in FIG. 15. Attached to the opposed, bottom edge is a mating or co-operating extrusion of the type shown at 170 in FIG. 6. With such an arrangement the hook-shaped configuration 171 of extrusion 170 is arranged so as to be engaged by and within the complementary hook-shaped configuration 163 of extrusion 160, thus to achieve and allow for selective relative pivotal movement between the extrusions 160 and 170, and associated glass panel 200.

When the arrangements/extrusions in accordance with the present invention are employed in a closure means or door of the sliding or rolling type, the end result is a product which is more easily assembled when compared with the known arrangements, lends itself to rolling or unrolling in an improved manner wherein there is no contact between panels, and hence no 09/03/04jfl 3940 spc,22 23 tendency for scratching or jamming, and yet also allows for rolling up or down in a more efficient, quieter manner, without sacrificing anything in terms of strength or load-carrying capability or security. The present applicant's arrangements are especially suited for use with panels of glass. The end result is a more desirable product, easier to clean and maintain, simpler to operate and, in general terms, cheaper than known and presently in use products.

The arrangement in accordance with the present invention may be employed in a variety of different constructional contexts. One of its principal advantages is that, readily and with no need for adjustment or any ancillary equipment or components, it is particularly suited for joining together components one or all of which is or are susceptible to significant expansion and/or contraction due to, for example, variations in temperature.
