Definitions

  • GUARDRAILS SUCH AS BALCONY BALUSTRADES Filed Jan. 25, 1967 United States Patent 47,645 7 Claims. (Cl. 256-22) ABSTRACT OF THE DISCLOSURE
  • the present invention is directed to a guardrail construction which may be delivered to the site of erection in a knock-down condition and quickly erected with a minimum of effort and time.
  • the top and bottom rails are of channel cross secton with inwardly directed stops.
  • the web of each rail is provided with spaced slots therethrough which are 'complemental to the cross section of the spacer bars carried therebetween.
  • Each spacer bar has a pair of spaced openings proximate their free ends, which openings cooperate with the stops on the top and bottom rails and the inner side of the webs of the rails to lock the spacer bars and rails into a unitary rigid construction when U-shaped pins are passed through the openings, the locking pins may be welded in place when assembled and a smooth cover plate slid over the entire construction.
  • This invention relates to a new kind of aesthetic guardrail such as a balcony balustrade, that can be conveniently and rapidly constructed with sectional members and simple securing means such as pegs in particular.
  • railings and guardrails consisting basically of bars assembled to handrails, using ordinary pegs, the bars and handrails being obtained by parting off light alloy sections of two different kinds.
  • each handrail consists of a flattened U-shaped web having openings formed therein the contours of which match the cross-section of the bars in order that the latter may be inserted into these openings until their end-sections butt against transversely extending thrust flanges formed on the sides of the U-section, opposite the web.
  • assembly is effected with two pegs, each of which is engaged into a sufficiently long conduit formed by two mutually opposed longitudinal channels provided respectively on one of the faces of the bar and on a guiding surface formed on the inner side of the handrail.
  • engaging a peg through a fairly long conduit constituted by two mutually independent elements is obviously a delicate and not very practical operation which furthermore calls for a costly corresponding adaptation of the side of the bar.
  • the present invention has for its object to overcome these drawbacks and to accordingly provide rigid railings capable of being rapidly and conveniently assembled or even dismantled, such railings comprising two handrail sections similar to the U-shaped handrails described precedingly, in which are assembled light bars of pleasing appearance, using a simple device and particularly a peg bearing against the handrail surface facing the thrust flanges.
  • each bar is formed with a thin solid web each edge of which is divided into two flanges shaped to substantially form a longitudinal dihedron, assembly being effected through the medium of two securing points spaced as far as possible from the longitudinal centerline of the bar and from each other.
  • the securing points are obtained by welding the end-section of the bar to the handrail thrust flanges, or by means of two pegs extending through the thin web of the bar, level with the handrail web.
  • the end-section of the bar may have a bearing surface for cooperation with the thrust flanges that is substantially equivalent to that of a tubular member of rectangular cross-section, but on the other hand a bar having a thin web will permit substantial savings of material in comparison with such a tubular member, as well as obviating the need for dies with mandrels, and consequently reducing the cost of fabrication. Further, welding limited to localized areas or engaging a peg through a single thin wall presents no difficulty even should such engagement be carried to the point of a force fit, so that pegs of conventional shape may be used. Moreover, such assembly methods'are entirely suitable for obtaining sloping staircase balustrades.
  • Such conventional pegs are preferably rigidly united with each other and form fork prongs, whereby such a built-up element permits simultaneous engagement of the two pegs into the thin web and results in a considerable saving in assembly labor costs.
  • the present invention further relates to an economical type of sectional member which is characterized in that it comprises a thin web each edge of which is divided into two longitudinal flanges which jointly form substantially a dihedron, said flanges being bulged to varying degrees and being possibly ribbed for greater eye-appeal.
  • the flanges of the sectional member are arranged symmetrically in relation to the web thereof as well as in relation to the transverse centerplane through the web, whereby a dual symmetry is achieved which greatly assists rapidity of assembly of the bars engaging into the sectional member since it obviates the need for any kind of selection before engaging the bars into the handrail openings.
  • FIGURE 1 is a perspective view of two rails and of bars about to be assembled thereto to form a balustrade according to the invention.
  • FIGURE 2 shows in cross-section the balustrade obtained with the elements in FIGURE 1.
  • FIGURE 3 is a cross-section on an enlarged scale of the bar used in FIGURES 1 and 2.
  • FIGURES 4a, 4b, 4c, 4d show in cross-section, on a smaller scale, four alternative types of bars in accordance with the present invention.
  • FIGURES 1 and 2 there is shown thereon a lower rail 51a and an upper rail 51b, both of which consist of identical light aluminium alloy sections and have a shallow U-shape in cross-section.
  • Said sections additionally have a longitudinal symmetry plane, and the sides 52 of the U are formed with inswept rims 53 the facing edges of which leave a longitudinal channel therebetween.
  • the web 54 of the section which corresponds to the base of the U, is formed with a plurality of uniformly spaced openings 55 therein, the contours of which match the cross-section of the bars 56 which they are adapted to receive.
  • the inner faces of rims 53 form transversely extending thrust surfaces against which the end-sections of the perfectly upright bars can butt.
  • Each bar 56 consists basically of a solid thin web 57 each edge of which is divided into two flanges 58 which jointly form, substantially, a dihedron. These identical flanges are arranged symmetrically in relation to the longitudinal and transverse centerplanes of the web. Since these planes are mutually perpendicular, the symmetry axis of the bar will be the intersection line of the two planes.
  • each bar 56 is secured to the lower rail, as will be explained in greater detail hereinafter, by the prongs of a fork 59 which engage into holes 60 formed in the bar web 57 and which bear tangentially against that surface of web 54 which faces the rail rims 53 acting as thrust surfaces.
  • the upper ends of the bars can then be masked by a handrail 61 in the form of a thin aluminium section each side of which is formed with an outswept surface and an inswept surface.
  • the handrail may be engaged over the longitudinal upper rail and restrained thereon by an elastic clip-on effect, with comparatively light pressure.
  • the lower ends of the bars can also be masked by similarly engaging, over the lower longitudinal rail, a lining 62 formed with spring flanges which securely clip into the gap between ridges formed on the facing rims of the rails.
  • the unusually aesthetic appearance of the bar 56 is to be noted, despite the fact that its shape is fairly similar to a conventional I-section.
  • the rounded flange edges 63 (see FIGURE 3) and the insweeps 65 and 66 have radii of curvature which are carefully chosen and blend in with the substantially thinned down middle part 67 of the web. This results in pleasantly rounded shapes, and it is diflicult to see how it would be possible to devise a thin-webbed section providing end bearing-sections comparable to those of the customary tubular section while at the same time yielding to aesthetic requirements.
  • sections can be contoured to suit the kind of lighting to which the bulustrades are to be exposed.
  • Such alternative embodiments can be formed in addition with longitudinal ribs which lend themselves particularly well'to the obtainment of shadow effects.
  • a demounted quick assembly guardrail construction comprising;
  • spacer bars having a web the cross-section of which is complemental to the slots in the web portion of said base and top rail and which together with the slots and inwardly directed flanges on said top and base rail define a rigid four point contact between the spacer bars and top and bottom rail, said spacer bar webs having adjacently spaced openings proximate the ends thereof lying in the plane of the web;
  • locking means adapted to be received through the adjacently spaced openings in said spacer bar webs when the spacer bars have been passed through the slots in the webs of said top and base rail so that the free ends of the spacer bars engage the inwardly directed stop means on said base and top rail, said locking means abutting over a major portion of its area against the inner surface of the web of said base and top rail.
  • closure cover means snuggly receivable over at least the top rail and having a geometric shape complemental t0 the top rail in its inverted condition to cover the open portion of said top rail to prevent tampering with the locking means and to hide same from view leaving a smooth uninterrupted surface to the hand of the beholder.
  • a guardrail as claimed in claim 1 wherein the locking means are U-shaped staple-like members having a cross-section complemental to the openings through the web of the spacer bars.
