Y LIFT MANUFACTURING PTY. LTD. AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT "IMPROVEMENTS IN BRACKETS" The following statement is a full description of this invention, including the best method of performing it known to us:- TITLE IMPROVEMENTS IN BRACKETS This Application is a divisional of the present applicant's Australian Patent Application No.2011250683, in turn a divisional of the present applicant's Australian Patent Application No.2008261157, and the whole contents thereof are included herein by reference. FIELD OF THE INVENTION [0001] The present invention relates, in general terms, to apparatus for use in the moving of objects between spaced-apart locations, and more particularly between locations which are spaced apart in the vertical or height direction. More particularly, but not exclusively, the invention relates to apparatus, as for example a bracket, for use in the lifting or moving of weighty articles, as for example from a first location or site of storage to a second location or site for use or installation on a building or the like structure. BACKGROUND OF THE INVENTION [0002] Throughout the ensuing specification reference will be made to a particular and preferred context of usage for the apparatus of the present invention, namely in the building/construction industry. It should be understood, however, that the apparatus in accordance with the present invention lends itself to usage in a variety of other contexts and that the invention is under no circumstances to be considered to be in any way limited or restricted to any preferred context of usage described in detail hereinafter. [0003] The invention in particular relates to fixing means or brackets, to be employed for releasably locating the apparatus in accordance with the present applicant's co-pending Australian Patent Application No.2008261157 relative to an erected frame and/or roof of a building or the like structure. [0004] For ease of explanation, hereinafter reference will be made to an especially preferred application for the apparatus in accordance with the present invention, namely in 04/10/12jm20299oct4.innov speci,I -2 the construction of a low profile multi-storey structure, as for example a house, warehouse, factory or the like. [0005] Throughout the ensuing description and claims the expressions "low profile multi-storey structure", or the alternative "low profile building or the structure" are intended to refer to low rise buildings or structures, whether for domestic or commercial use. [0006] In the building industry, for example, these days there is a preferment for any and all external walls, as well as internal walls such as party or boundary walls, to be constructed from bricks or the like materials. When compared with timber and the equivalent materials, bricks or the like have a number of advantages, in terms of durability and hence a reduced need for ongoing and regular maintenance, enhanced heat and sound insulation capabilities and improved strength thereof. However the use of bricks or the like for the construction of external walls, as well as internal walls such as party or boundary walls, gives rise to disadvantages in terms of cost, overall weight of the finished structure and case of construction thereof, especially when a multi-storey structure is involved. This is especially the case with low profile, as distinct from high rise structure. In practical terms a wall of timber or similar lighter weight material is generally easier, quicker and cheaper to construct than an equivalent wall of bricks or the like. Further, and when a two-storey or low profile but multi-storey structure is involved, the increased weight of brickwork, as compared with timber or the like material, will mean that more secure foundations etc. are required with bricks or the like than with timber as the material of construction. [0007] These disadvantages have been found, in many instances, to discourage or deter a builder, let alone a buyer or possible houseowner, from using bricks, especially on upper or elevated levels of a multi-storey house or similar structure, this despite the aforementioned advantages associated with the use of bricks or the like. Indeed, there is wide-spread practice in the building industry to use timber and other lighter weight materials for the construction of outer and inner walls of a building, especially for an upper floor or storey of a low profile structure. 04/10/12jm2O299oct4Jnnov speci.2 V I J /VV / - J / [00081 As a substitute flbi bricks and the like what are referred to as aerated concrete panels or blocks, as ommercially available for example under the trade mark "HEBEL", may be used, Such a material has the advantage of exhibiting, by its very nature, a significant degree of both heat and sound insulation and, furthermore, for any given wall area will result in the creation of a structure of much reduced weight when compared with an equivalent wall constructed of bricks or the like. Such material is available in panels or blocks having an overall weight of the order of 91.8 kg. Such panels, when installed on a building frame, can afford equivalent, iC not better, properties than bricks - in tears of case of installation, heat and sound insulation - yet give rise to a wall which is much less weighty vhcn compared with an equivalent wall of brick. However in this day and age of improved, stricter occupational health and safety standards, there still remains the problems associated with installation of such panels, especially at an elevated location. [0009] The present invention. Lherefore, seeks to assist in overcoming the problems and disadvantages associated with the known art by providing an apparatus which will allow a weighty object, as for example a IIEBEL (Trade Mark) panel of the aforementioned type, to be safely, readily and easily moved, as for example from ground level to an upper or elevated level at a proposed site of erection of a low profile structure or in fact from any location for storage to a location for use or installation on a low profile building or the like structure. [0010]1 In accordance with the present invention there is provided a bracket assembly for use in the construction of a party wall or boundary wall of a low profile building or the like structure, said bracket assembly including a top member, of a substantially hollow construction, having an armn member extending substantially normally thereto and disposed at or in the vicinity of a free end thereof; a bottom member, of a substantially hollow construction; and an intermediate member. of a substantially hollow construction, adapted in use to be releasably connectable to each of said top and bottom members, and wherein said top member is adapted, in use, to protrude beyond the roof-line of said building or the like structure, said arm member j..-2( ~ ot,,i A - I .3a having associated therewith a bracket which includes two juxtaposed plate members each having opposed apertures formed therein, said apertures being adapted to have located therethrough, in use, fixing means, a plate member extending substantially normally from each of said juxtaposed plate members, each said plate member having an array of apertures formed at spaced-apart locations along the length thereof, said apertures in use being adapted to have extending therethrough fixing means adapted to protrude into a roof truss interposed between said plate members, wherein said bracket is adapted to receive and releasably retain a guide rail or the like along which a winch or the like lifting means is adapted to travel, I7/06l~Ifd..-20299 - Spr pp -4 [0011] In order that the invention may be more clearly understood and put into practical effect there shall now be described in detail preferred constructions of an apparatus in accordance with the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS [0033] With reference now to FIGS. 1 to 4 of the drawings, there is shown therein a block, sheet or panel, generally designated 1, of the type sometimes used nowadays for construction of a wall of a building of any type. As stated earlier such will preferably be in the form of panels of an aerated concrete material, as for example of the type commercially available under the Trade Mark HEBEL. Such panels I have been used for quite some time now in the construction industry, but have met with only limited acceptance and use by virtue of the problems associated with actual installation thereof, this especially on an elevated structure, as for example a multi-storey structure. [0034] The prior art procedures in order to comply with occupational health and safety standards, and this nowadays applies to any multi-storey structure, necessitated the building of a scaffold and the manual lifting of a panel (or multiple panels 1) to the proposed site of installation (relative to the building frame). Traditionally such panels 1, having a width of the order of 600 mm and a length of up to approximately 3 metres, have weight of the order of 91.8 kg. By reason of the problems associated with lifting such panels 1, a practice has been adopted of using blocks or panels having a width of 600 mm at lower levels and lighter blocks or panels, having a width of the order of 300 mm, at upper levels. Such has given rise to an increase in the amount of time and effort associated with installation of such blocks or panels 1 at upper levels. Present methods for lifting/delivering such weighty blocks or panels to an elevated site for installation suffer in terms of occupational health and safety criteria. Such methods have involved one or more individually physically lifting and moving such blocks or panels. Such is a physically draining and, perhaps more importantly, potentially dangerous practice. 04/10/12jm202990ct4.innov speci,6 -7 [0035] The practice is to raise a block or panel I from ground level to a proposed site of installation, as for example the first floor of a two-storey structure, such panel I then to be affixed in place, using any suitable fixing means as for example threaded members 2, which co-operate with one or more appropriately spaced-apart battens 3 previously affixed to studs or the like 4 of the overall building structure in any suitable manner, as for example by threaded members 5. [0036] Turning now to FIG. 3 there is shown therein one possible means, to facilitate lifting of a panel 1. Such is in the form of a sling 6, adapted in use to extend around a block or panel 1. The sling 6 will preferably be formed from any suitable and substantially non-elastic material, having a loop 7 formed in each free end thereof. A releasable clamp means generally designated 8 (of any known and suitable type), will be connectable to the sling 6 as shown, in turn being connected, in any suitable way and using any known means, to a cable or like 9 to be associated with a suitable lifting means, as for example a winch, hoist or the like. [0037] FIG. 4 illustrates an alternative means for use in lifting a block or panel 1. Such will take the form of an assembly of a hollow tubular member 10, of a length just slightly greater than the width of the block or panel 1, having releasably associated therewith at least one, and preferably two, opposed downwardly-depending members 11, each having at least one aperture formed therein. The tubular member 10 includes an integral eyelet or the like 12 adapted in use to releasably co-operate with a clamp means 8 and associated cable 9. The arrangement is such that one or more fixing means 13 of any known type may be utilised to releasably affix block or panel I to the opposed members 11, to retain said block or panel I in place relative to said tubular member 10 during lifting thereof. [0038] In the preferred embodiment illustrated each member 11 takes the form of an elongate plate-like member of any suitable material, preferably a metal, having at one end thereof an extension 14 of a shape substantially complementary to the cross-sectional shape of the tubular member 10. The arrangement is such that, in use, a member 11 preferably is located at or in the vicinity of each free end of the tubular member 10, to be releasably connectable to said tubular member 10 by bringing the free end of a threaded 04/10/12jm202990ct4.innov speci,7 -8 member 15 into contact with the outer surface of said tubular member 10 in a pressure-type fit. [0039] FIG. 5 shows the principal components of an apparatus which, in use and with the further utilisation of one or more brackets - to be described later in this specification in more detail - is intended to be appropriately located relative to building framework to allow for installation thereon of panels of aerated concrete or the like material, to form or construct external and/or internal walls of the overall structure. Later in this specification reference will be made to a number of different types of brackets, to be used dependent upon the nature of the building being constructed. In particular the following types of brackets may be employed: [0040] (i) a truss tail bracket - for the situation wherein the building being constructed is to include eaves around the periphery thereof; [00411 ii) a cantilever or off-set bracket - for the situation wherein there are no eaves on the building or if the roof is under construction; [0042] (iii) an adjustable arm wall bracket; and [0043] (iv) a flat roof bracket, hereinafter also referred to as a party-boundary bracket, to be used where there is a party or boundary wall. [0044] In actual fact the overall apparatus, including the brackets in accordance with the invention may be offered - for sale, lease or rent - in kit form. [0045] Again with reference to FIG. 5, the apparatus includes a track or the like 20, preferably constructed from galvanised iron, such adapted in use to extend across that area of the frame of the building or the like structure on or in relation to which a wall is to be constructed. A winch or the like lifting means 21, preferably electrically operated, is in use associated with said track 20, to be selectively and controllably movable along such track 20 as required. The winch, hoist or the like lifting means 21 includes a retractable chain or cable 9, with associated hook or the like clamp means 8, intended to co-operate with a 04/10/12jm20299oct4.innov speci,8 -9 means for releasably retaining one or more "HEBEL" type panels, as for example those shown in FIGS. 3 and 4, whereby to transport such panel or panels I to an elevated site for installation, as by affixture to battens 3 attached to studs 4 of the building frame itself. [0046] In the embodiment illustrated the track 20, constructed of galvabond or the like material, may be a similar shape and configuration to that used in sliding door hardware. The track 20 has associated therewith, and in use spaced a predetermined distance therefrom, a length of rail 22 (preferably hollow tubular) which has, associated therewith by means of a plurality of brackets 23 (or in any other suitable manner) the winch, hoist or the like 21, that rail 22 serving as a carrier for the winch, hoist or the like 21. Removably associated with and extending transversely of the rail 22 there are provided, at spaced-apart locations along the length thereof, more particularly at or in the vicinity of the free ends thereof, hangers 24, of the type commonly employed in sliding door hardware. Such hangers 24 allow the winch to move, or be moved, along the track 20. By being controllably movable along the track 20 as and when required, the apparatus is suited to use for lifting and installing a plurality of panels 1, aligned both vertically and horizontally, to create the requisite wall. [0047] In the embodiment of FIG. 5 the track 20 has associated therewith, preferably at or in the vicinity of each free end thereof, a side fix bracket 25 and associated locking pin 25a, of the type shown in FIG. 6 in particular. [0048] The track 20 further includes, at predetermined locations along the length thereof, further bracket means 26. In the embodiment of FIG. 5 such is in the form of an overhead bracket, to assist in installation of the overall apparatus for purposes of use. The overhead bracket 26, as shown in exploded view in FIG. 7, is made up of mating male and female members 27, 28 which are adapted, in use, to be located around the track 20, with threaded bolts or the like 29 to be located within shaped and opposed slots 30 of the female member 28 and to be affixed therein by means of co-operating nuts 31. As shown in FIG. 5, for example, the threaded bolts 29 and co-operating nuts 31 protrude upwardly of the overhead bracket 26 to allow for connection with further brackets of the type referred to earlier. Both the male and female members 27, 28 include an aperture 32 which is adapted 04/10/12jm20299oct4innov speci,9 - 10 to receive and releasably retain therein a threaded bolt or the like 33, to affix the overall bracket 26 in place relative to the rail 20. [0049] With reference now to FIGS. 9 to 11, such show an apparatus for lifting in place on a structure having an eaved roof. The overall apparatus, as shown in FIG. 5, is attached to roof trusses 40 by means of roof truss tail brackets, generally designated 41 and shown in more detail in FIG. 11. Such roof truss tail bracket 41 is releasably affixed to a roof truss 40 at or in the vicinity of the free end thereof, and is adapted in use to co-operate with the overhead bracket 26 of the type shown in FIG. 7. The winch, hoist or the like 21 can then operate to travel along the track 20 as required to each site for installation of a panel 1. [0050] The truss tail bracket 41 as shown preferably of a metal, includes a base assembly, made up of two juxtaposed plates 42, 43 each having opposed apertures 44 formed therein, such to have located therethrough in use, the bolts 29 of overhead bracket 26. Extending substantially normally from plate 42 are opposed plate members 45, 46 each having an array of apertures 47 formed at spaced-apart locations along the height thereof, such apertures in use to have extending therethrough fixing means 48, to protrude into a roof truss 40 interposed between the plate members 45, 46, as shown in FIG. 9. [0051] Turning now to FIGS. 12 to 15, there is shown in FIG. 12 for example the apparatus to be used on a structure without an eave. To allow for use of the method and apparatus in such a context, the overall apparatus further has associated therewith a plurality of beams 50, to be located as shown by means of a plurality of cantilever beam brackets 51 of the aforementioned type. As shown, for example, in FIGS. 15a, 15b and 15c, a plurality of variants of the bracket 51 may be used, dependent on the desired location. By way of example, at or in the vicinity of the free end of the or each beam 50 there will be provided a bracket 52 of the type shown in FIG. 15c, to co-operate with an overhead bracket 26 for receiving track 20 and associated with 21. At other locations along the beam 50 there may be employed brackets 53, 54 of the type shown in FIGS. 15a and 15b, of a similar nature to that shown in FIG. 4. 04110/12jm20299oct4innov speci,10 - 11 [0052] FIGS. 16 and 17 show yet another variant, wherein the track 20 and associated hoist 21 are best fitted/attached to a wall stud 4, by means of a wall stud bracket 60. Such bracket 60, as shown in more detail in FIG. 17 preferably includes two telescoping members 61 and 62, of hollow tubular construction, with member 62 having, at the free end thereof, a pivotable extension member 63 having means 64 associated therewith for releasable connection with an overhead bracket 26. Pivotably attached to the free end of the member 61 are two arm members 65, 66, each being provided at the free end thereof with clamping means 67, preferably in the form of a U-shaped member, to be disposed around a stud 4 as shown in FIG. 16 and to be releasably affixed thereto in any suitable manner and using any suitable means, as for example a plurality of threaded members 68. [0053] In FIG. 18 there is shown a variant of the arrangement of FIGS. 16 and 17, wherein the second member 62 of the bracket 60 is of an extended length, whereby to be readily adjustable to suit differing use requirements. [0054] FIGS. 19 to 21, including 21a, show further variants of fixing brackets 70, 71 and 72 for use in accordance with the invention. [0055] With reference now to FIG.20, such shows an arrangement which is best suited for use with the method and apparatus of the present applicant's Australian Patent Application No.2008261157 for the construction of a party or boundary wall. [0056] The arrangement of FIG.20, especially intended for use in the construction of party or boundary walls, includes a plurality of spaced-apart upright members, generally designated 100, which are adapted, in use, to be affixed - in any known manner and by any known means - to a stud (not shown) of a building or the like structure. Each upright member 100 includes, at or in the vicinity of the top end thereof, an elongate member 101 adapted, in use, to protrude normally thereto and to be braced thereto by means of one or more bracing members 102. The or each elongate member 101 is adapted, in use, to have releasably affixed thereto at or in the vicinity of the free end thereof a bracket means 26, in turn adapted to receive and releasably retain a track or the like 20. 04/1O/12jm20299oct4.innov speciJ I - 12 [00571 With particular reference to FIG. 21a, there is illustrated therein an arrangement wherein a top bracket, designated as 80, can be associated with and preferably be slidably located within, an extension member 81, to give rise to an overall bracket which is adjustable in its height or length dimension. In like manner a bottom bracket, generally designated 82, can be slidably connectable to the other end of the extension member 81. Preferably the extension member 81 is of such a length as to allow for an overall height or length of the assembly of it between 900mm and 6 metres. [0058] Turning then to FIG.22, such shows a variant of an adjustable bracket assembly of the present invention. The assembly is made up of at least three members 150, 151 and 153 as shown, each in the form of a hollow tubular elongate member, of any given cross-sectional shape, but preferably having a substantially square tubular cross-section as shown. The members 150, 151 and 152 are, in use, adapted to co-operate with one another, with the members 150 and 152 being, for example, slidably receivable within the member 151 in a telescoping manner. Means will be provided to releasably affix each member 150 and 152 relative to member 152 at a given position thereon dependent on the intended usage for the overall bracket assembly. In practice, however, the length of each of the members 150, 151 and 152 may be varied. [00591 The member 150 has, extending substantially normally thereto, and preferably releasably associated therewith in any known manner and using any known means, a further member 153, which is braced relative to member 150 by a bracing member 154. The member 153 has a cap or the like 155 at the free end thereof. In use the type referred to earlier in the description and illustrated in the drawings, intended to receive and releasably retail a rail 20. [0060] Both the members 151 and 152 have a plate member 156 associated therewith, such having an array of holes 157 extending along the longitudinal dimension thereof. [0061] In use a plurality of upright members will be disposed, in spaced-apart relationship, across the frame of the building or the like structure, with the rail 20 associated therewith. The apparatus of the present applicant's Australian Patent 04/10/12jm202 99 oct 4 .innov speci, 12 - 13 Application No.2008261157 can then be associated with that rail 20 and use for purpose of lifting objects, as for example HEBEL (trade mark) blocks, from the ground to the desired position for installation. [0062] The bracket assembly as shown in FIG.22 is especially suited for installation of blocks or panels in the gap 100 shown in FIG.24. Such bracket assembly is a variant of that shown, for example, in FIG.2 Ia. The bracket assembly is made up of three (3) separate and mutually co-operable components adapted, in use, to be releasably affixed - in any known manner and using any known means - to be releasably affixed - in any known manner and using any known means - to the framework of the overall building, as shown in FIG.24, and end component which is intended, in use, to be disposed above the roof truss or framework, again as shown in FIG.24, and an intermediate or extension member which is adapted, in use, to be separately and releasably connectable - again in any known manner and using any known means - to the components. [0063] The arrangement is such that, when a party or boundary wall in involved, a plurality of bracket assemblies can be disposed across the structure or building, and levelled as appropriate, thereby to receive and releasably retain a rail or track 20 which, in turn, is adapted to have associated therewith the apparatus of the present applicant's accepted Australian Patent Application No.2008261157. [0064] Turning then to FIG.23, there is shown therein an arrangement in accordance with the present invention intended for use in receiving and releasably retaining, for lifting as and when desired of a block or panel 1. Such is a variant of that shown, for example, in FIG.4. Such includes a hollow tubular member 200, preferably of a substantial L-shape as shown, and of a length which is just slidably greater than the width of the block or panel 1 to be lifted, such having releasably associated therewith an assembly 210, to receive and releasably retain a block or panel 1, which acts to clamp the upper end of such block or panel 1. The arrangement includes a plurality of spaced-apart apertures 200 as shown, such being adapted to have a fixing means 230 disposed in use therethrough, to engage with the block or panel 1. 04/10/12jm20299oct4innov speci, 13 -14 [0065] The situation often arises in low profile structures wherein adjoining or juxtaposed buildings are to "share" a common wall, referred to as a party or boundary wall. Such a situation is illustrated, for example, in FIG.24. Therein there is a gap 100 between adjacent or juxtaposed buildings 110, 120 which is adapted to have located therein a plurality of panels or blocks 1. In the preferred embodiment illustrated the adjacent or juxtaposed buildings 110, 120 are two-storey each, having a roof 130 associated therewith. [0066] The brackets in accordance with the present invention have been found to be responsible for a number of practical advantages, when compared with the prior art. [0067] First of all the brackets are responsible for a significant improvement in terms of ease of installation. By way of example, in this day and age occupational health and safety standards require that, in the construction industry, and especially where a multi-storey structure is involved, extensive safety scaffolding must first of all be erected, extending across effectively the entire work area, prior to commencement of construction of a brick wall for example. Apart from the overall costs associated with purchasing, renting or leasing the various components required to make up such a safety scaffolding structure, there is a significant amount of time involved in the actual erection and dismantling thereof. With the present applicant's method and apparatus, and using the brackets in accordance with the invention, the need for such scaffolding is reduced. [0068] With multi-storey structures, when the external walls are formed from brickwork and the like, the higher the structure itself the greater the load which needs to be borne by foundations, etc. With the preferred context of usage of the present invention, involving the use of HEBEL (trade mark) blocks or panels, such panels for any given area of wall are significantly lighter when compared with a brick structure of the same dimensions. Indeed, in real terms such walls constructed for panels will be up to only one third of the weight of an equivalent wall of brick. Such will mean, in practical terms, that there may no longer be a need in any multi-storey structure to have the external walls of the or each upper storey formed from a light weight material (meaning timber or the like), as has been a common practice in the past to reduce load exerted on foundations, etc.. By utilising such HEBEL (trade mark) panels or blocks, to cover all external walls of a given 04/IO/12jm20299oct4innov speci. 14 - 15 structure, there can be expected to be achieved a significant improvement in sound and heat insulation, when compared with the prior art composite brick/timber structures. [0069] In terms of actual cost, apart from reducing the need for preliminary construction of scaffolding and the like, the actual cost of utilising HEBEL (trade mark) panels in an external wall has been found to be significantly less than if bricks or the like were to be employed in that same wall. [0070] The apparatus, with brackets, will also allow for erection of an external wall for a given structure in much less time than would be involved if a brick wall was being constructed. This again means a further reduction in the overall cost of construction of any given structure. [0071] To be more specific, using the lifting apparatus and brackets in accordance with the present invention gives rise to a significant reduction in construction time - this when compared to prior art practices. Apart from a saving in cost in terms of material, this significant saving in time - and ease - of construction represents an important practical and economic advantage attributable to the invention.
