Definitions

  • This invention relates to a barrier, a method of assembly of a barrier, and components for use in a barrier.
  • a gkraft sheet is held by having each of its side vortical edges within a slot within an aluminum extrusion, but again an upper edge of the glass in many cases is then located so that ft is vulnerable to accidental impact.
  • a barrier using a glass sheet as the main material providing the barrier effect shall include an upper railing.
  • the glass sheet is being used as a barrier for a balcony, such glass will be selected from those which provide resistance to impact, or in the event of impact will not break into sharp shards which may then further injure either the person impacting the glass sheet or cause injury to those who might be below the balcony somewhere.
  • Such glass is known (toughened glass is an example) and would be an appropriate glass to be used in such an application but it is known that this glass is particularly vulnerable to impact against its edge.
  • a further orobler ⁇ currently in providing barriers using predominately glass sheets is that they will either have a lower edge above a ground base for instance the floor or top of a slab of a balcony or, a further current system, involves embedding a bottom edge of the glass sheet in a slot cut into the floor or slab or similar of the balcony.
  • One of these problems is directed to enabling a rectilinear glass sheet to be used as ⁇ barrier which technique also facilitates the use of stainless steel and provides a practical arrangement that facilitates installation and also replacement rf ever necessary.
  • the invention in one form can be said to reside in a barrier including an upper railing supported between and by two upright posts, a transparent or translucent sheet having an upper edge nesting within and being supported by a slot within the upper railing, a first side edge of the sheet being spaced apart from a first adjacent vertical post supporting the railing, and a second side edge of the sheet which is oppositely positioned with respect to the first side edge being spaced apart from a second adjacent vertical post supporting the railing, a lower railing having a slot receiving a lower edge of the sheet, and means to enable the upper railing to be raised or lowered with respect to the sheet so as to facilitate installation and replacement of the sheet.
  • a lower railing can either be fixed in position between the posts leaving a lower gap between an upper surface of the flooring or slab of the balcony and the railing, or it means that the lower railrng can be positioned directly on and therefore leaving no effective gap there between of the upper surface of a slab or flooring of a balcony as a typical instance and the lower edge of the lower railing.
  • the upper railing is provided as a longitudinally extending hollow member with the slot being a slot within the wall of the hollow shape but there also being an inner material providing at least some fill which wo jld be selected to be soft against any glass edge but also provide a seat against which at least some of the glass can be bedded against when within the slot
  • such infill material is a foamed plastics material adapted to resilie ⁇ tly engage around and provide a resilient reaction where more of the glass sheet or indeed any translucent sheet if this be the case, is required to be accommodated along one portion of the upper railing slot as compared to another.
  • the upper railing can be both adjusted in absolute height and it can also be adjusted to ensure that its alignment will be horizontal even with varying sloping floor positions.
  • This technique also enables stainless steel to be used particularly for the upper railing and if desired for a lower railing. This is a preferred material but historically has not been conveniently been able to be used in this type of application.
  • one of the problems with using a hollow member with a slot specifically for the upper railing and also when appropriate for a lower railing is that where the glass finishes and there is therefore a distance between the glass and the upright post or indeed prior to a respective end of the railing, there will be a gap that will either enable insects and dirt to get within the hollow of the railing or at the least this will look unsightly.
  • a slot within the upper railing is co-terminus with the upper edge length of a respective transparent or translucent sheet.
  • a tube to be used as an upper railing is filled with a catalysed plastic monomer such that the tube then is filled subsequently with expanded plastic foam which, by appropriate selection of plastics materials, will provide firstly adhesion to the inner walls of the tube and then subsequent strengthening of these against any subsequent expansion or bowing and furthermore, will provide an appropriate resilient seat against which an edge of the transparent or translucent sheet can then engage and also provide tolerance as previously clarified.
  • a methoc of the invention then includes steps for installation of a transparent or translucent sheet as a barrier between adjacent vertical posts and an upper and lowe " railing, the steps of inserting a lower edge of the sheet into a slot within a lower railing, then lowering the upper railing with respect to the respective upright posts while aligning the upper edge of the glass or other sheet with a slot within the upper railing and then affixing the respective ends of the upper railing to the respective upright post.
  • the method further includes as a preliminary step, to provide a filler of expanded plastics foam within a hollow tube providing the upper railing.
  • an appropriate slot within the tube which will receive a plug similar to the expected upper edge alignment and shape of the glass or other sheet then filling the hollow of the railing with plastic monomer catalysed to effect an expandec plastics foam, then withdrawing the plug and then subsequently fitting the railing as an upper railing in the manner described.
  • Such a sealant can be of any conventionally available material which is used to fill gaps and adhere appropriately to the selected sheet material if desired and this is often referred to as a silicone rubber material although it is not intended that this should necessarily be limited to such a type of materia!.
  • a fixed lower railing in the event that a fixed lower railing is to be positioned to leave a space beneath the glass sheet and an upper surface of a floor or slab, then such a lower railing can also be used which is fixed in its position with respect to the side upright posts and otherwise can also be of a structure being hollow with a slot cut to be co terminus with the width of a glass sheet or other, and to be prefilled as appropriate with an infill material such as a foam expanded plastics material.
  • the invention may be said to reside in a method of facilitating a barrier of indefinite length where there are at least three spaced apart upright posts parallel one with the other, an upper rail extending between respective posts and a lower rail parallel to the upper rail extending between respective posts, and transparent or translucent planar sheets held between respective upper and lower rails, means supporting the upper rail which allow for the rail to be changed in relative height with respect to the lower rail, each sheet being of rectangular proportions and being positioned so that its side edges are parallel to each adjacent upright post, the method including as a preliminary step to facilitating the barrier, of selecting a common sheet size from a small number of previously manufactured sheets of standard sizes and then adjusting distance between each edge of each sheet and either an adjacent sheet or an edge of a post so that these are of equal size, sheet to post or sheet to sheet, and also adjusting the number of upright posts to be equally spaced between end posts to accommodate the sheets and chosen spacing between them and the posts.

  • this is constituted by a barrier 1 which includes two io spaced apart vertical posts 2 and 3 which are supported in conjunction with a lower railing 4 which in turn is supported so as to engage with and sit directly onto an upper surface 5 of a slab 6.
  • the lower railing in this case is constituted by a metal strip 7, which is attached by any suitable means to the top of the slab 6.
  • a plug 8 which is 15 attached by a mutually screw threaded shaft 9 so that the upper post 2 which is of hollow cylindrical shape sits on and is positively supported by the plug 8.
  • This molding 14 has on one side a shape adapted to wrap around a portion of the cyl ⁇ drical shape of the post 2 and its further end is adapted to engage 25 with nesting fit, an end of a cylindrical tube which forms an upper railing 16.
  • This upper railing 16 is adjustable in height relative to the post 2 at one end and the post 3 at the other by the same mechanism in which there is a tightenable bolt engaging through an uppermost open slot. It is this mechanism then that allows the upper railing 16 to be moved upwardly or downwardly within the limits of the slot or being lifted entirely from the slot.
  • the top of the upright post 2 has a removable cap 17 which will normally be in a position closing the top of the post but which can be removed to enable access to the head of the bolt 13 and we have shown several examples of spanner or ball ended Allen key to effect such tightening.
  • this is comprised of a thin walled stainless steel tube which has had cut through some of its length but not all of its length, a slot coinciding with an expected width of glass sheet that will be embedded there through and supported thereby.
  • a bottom metal plate 7 which in this case is sitting on the upper surface 5 of the slab 6 and such that it would either allow no or negligible passage of water there past in a typical draining situation as might occur on the edge of a balcony.

  • Figures 3 and 4 show alternate ways in which the bolt 13 in the one case as shown in Figure 3 or the bolt 14 in the other case as shown in Figure 4 can be appropriately accessed.
  • the bolt has a hexagonal head
  • there is a bolt with a head having a hexagonal aperture so that an Allen key 22 with a ball head can be used for tightening of this conveniently at a modest angle.
  • the tube 30 has a slot 31 cut along some of its length which is chosen so as to be substantively co terminus, allowing for infill of silicone rubber or sealant material, and then one of the ends is locked by a plug 32 and.the slots are filled by plugs 33 and 34 which in each case include a capping 35 of silicone rubber.
  • tube 30 is then upended and a liquid mixture of just catalysed plastic monomer is then poured using an appropriate container 36 and then tube 30 is then left for the foam, in this case polyurethane foam to appropriately expand and polymerise and eventually cure.
  • foam in this case polyurethane foam to appropriately expand and polymerise and eventually cure.
  • a sealant rubber such as that from which the capping 35 is made, will not adhere to polyurethane foam so this can then be removed or it can be left in place with the plug only being removed and thereafter with the polyurethane foam 36 as an infill, a glass sheet 37 can then be appropriately inserted into the slot.
  • Figures 11 through 15 illustrate alternate configurations for an upper railing but showing h each case that a slot will not extend the full length of the tube 41 in the case of Figure 13 but will include two further sections 42 and 43 for instance.
  • each slot is selected so as to be co terminus with the width of a sheet of f a ⁇ sparent or translucent material which would typically be toughened glass of planar configuration and this has the specific advantage that the stainless steel which is usually wrapped under tension and then joined together to form a circular tube will exhibit only marginal spreading subsequent to such a cut being performed.

  • an appropriate sealant such as a silicone rubber shown at 58 for the upper railing i o and 59 for the lower raili ⁇ g.
  • This application is appropriate for people who are not wishing to have the barrier provide a seal against water overflow from a balcony or other surface.
  • the barrier 60 again has co terminus slots in an upper 15 railing 61 and 62 and the upper railing in both cases is adjustably secured with respect to each of the upright posts 63 in the one case, 64 in a further case and 65 in another case.
  • Figure 20 simply shows the functional elements of the first embodiment but does also show the alignment of a rectangular sheet of glass where the upper edge at 72 is further intruding into more compressed urethane foam thus holding the sheet relatively secure but allowing for a sloping bottom support 74.

Moreover, the slots 108 in each of these components are of the same width, and align when the twoo components are overlapping.
  • the free ends of the components of the assembled lower rail are shaped so as to nest around the posts of the barrier, although an alternative fs for there to be a hole through a rail component so that this rail component must be located over and slid down the post, this being considered a preferable way5 to finish the lower railing at an end of the barrier.
  • this telescoping lower rail 102 may be located by clips that are fixed to the floor surface supporting the barrier, and which include upwardly extending , wings that locate the lower rail in position.

  • This is also a larger clip 122 which is sized so that the wings 124 of this extend up and register against the outside surface of the sidewalls of the outermost of the two components.
  • FIG. 23 where there is illustrated a barrier 150 of similar construction to that illustrated in Figure 16, in that the lower rail 152 extends between the posts 154 so as to be suspended above the floor level, this barrier differing in that the slot 156 in the lower rail 152 extends right0 through this, from one end to the other.
  • the upper rail 158 may be similarly slotted in this fashion.
  • the inventor has ascertained that using a barrier having either telescoping rails or rails having a continuous slot passing there through as described in the embodiments above, will enable the customization of the barrier to any application using only two different Off the shelf, commercially available sizes of glass sheet, by adjusting the gap between respective sheets and/or posts. This eliminates the need to customize the size of the glass sheet to the application, thereby minimizing the cost of the glass, which is made more expensive where custom sizes must be provided.
  • the invention in its broadest sense is not intended to limit the application to simply stainless steel materials and it is not intended to be limited to glass although both of these materials have unique advantages and it would be expected that the invention will be mainly applicable to the use of stainless steel and to toughened or similar glass sheet.
