Definitions

  • ABSTRACT o e gn Application Priority Data The invention relates to an improved guard-rail, such Nov. 29, 1971 France 71.42605 as a pro ive g ard-rail or a guard-rail forming a fence, characterized in that each bar may be put in [52] U.S. Cl 256/22, 52/627, 256/59 pl in ividually by fa tening its lower end to a bot- [51] Int.
  • the invention relates to an improved guard-rail, for instance a protective guard-rail, particularly for balconies, or a guard-rail forming a fence; the invention also covers a method for assembling this guard-rail.
  • guard-rails are mainly of two kinds: those completely assembled in the plant and transported in this condition for installation at the building site; and those delivered to the building site in separate elements for assembly in situ.
  • guard-rails have one disadvantage in common, namely, they are difficult to install.
  • guard-rails are installed after all of the elements have been assembled along the entire length of the guard-rail, and this applies whether assembly takes place in the plant, as in the case of guard-rails of the first kind, or at the building site on a horizontal surface close to where it is to be installed, as in the case of guard-rails of the second kind.
  • the correct positioning and anchoring of the elements of such pre-assembled guard-rails, along the entire length of the rail is a delicate job in actual practice and requires a considerable amount of labour, especially when long lengths are involved.
  • guard-rails of the first kind, assembled in the plant are difficult to handle and result in high transportation costs because of their dimensions.
  • the guard-rail comprises substantially vertical stiffeners, a substantially horizontal bottom rail secured to the lower portion of the stiffeners, a substantially horizontal top rail secured to the upper portion of the stiffeners, a top hand-rail attached to the top rail and, finally, a series of bars, each of which is attached by one end to the bottom rail and, by the other end, to the top rail; according to the invention, this top rail is provided with a notch for each bar, the notches being open on one side of the rail and the bars being located in the notches.
  • the hand-rail attached to the top rail has a flange which closes off the notches and thus imprisons the bars therein.
  • a guard-rail of this kind is installed element by element, no prior assembly of the structure being required before securing or anchoring.
  • the installation proceeds as follows:
  • stiffeners are first of all anchored substantially vertically in place
  • the top rail is attached to the upper ends of the stiffeners
  • each bar is set in place individually by securing its lower end to the bottom rail in a conventional manner and by entering its upper end into the corresponding notch in the top rail;
  • the hand-rail is attached to the top rail in a manner such that the flange thereof closes off the notches in the top rail and thus secures the bars, which are therefore integrated into the structure.
  • FIG. 1 is a partial view, in perspective, of a guard-rail according to the invention, in the process of being assembled;
  • FIG. 2 shows a vertical section through the guard-rail in a plane located between two bars
  • FIG. 3 is a section similar to that in FIG. 2 through another example of embodiment of the guard-rail.
  • FIG. 4 is a detail, in part section, of the top rail at one of the notches in which the bars of the guard-rail are received.
  • the guard-rail illustrated by way of example in FIGS. I and 2, comprises stiffeners l which are the first elements placed in position; these stiffeners may be solid, tubular, or tubular with a reinforcing steel core; they may be placed in position by securing them directly into a paving block, or by securing them to such block by means of plates previously fixed into the block; they may equally well be secured by any other similar arrangement, such as by means of pins.
  • the guard-rail also comprises a bottom rail 2 placed in position after the stiffeners have been anchored.
  • this bottom rail consists of a C- shaped section having flanges 3 and 4 therebeneath; at each stiffener, the rail has an aperture which allows it to be placed in position by entering the stiffener into the aperture and allowing the bottom rail to slide down until it comes to rest on pins 5 secured to the stiffeners in order to support the rail.
  • the top surface of the bottom rail is also provided with openings 6 shaped to the profile of bars 7.
  • top rail 8 is attached to the upper ends thereof by any suitable means, more particularly by bolts 9 screwed into tapped holes in the upper ends of the stiffeners.
  • Top rail 8 has notches 10 which are open on one side and are arranged to correspond with openings 6 in the bottom rail.
  • Each bar 7 is then individually positioned between the bottom and top rails, the lower end of the bar being first of all introduced into an opening 6 in the bottom rail and the upper end being then entered (in the direction of arrow F in FIG. 1) into the appropriate notch 10 in the top rail.
  • each bar rests on bends 3 and 4 of the bottom rail, while the upper end rests against a flange 11 with which the top rail is equipped for this purpose.
  • a hand-rail 12 equipped with a flange 13 closing off the notches, is snapped on to top rail 8 in the conventional manner. Assembling the bars thus requires no separate accessories such as locking screws, nuts, pins, or the like; this eliminates the loss of time occurring during assembly of conventional guard-rails if any parts are missing.
  • each bar may be provided, at the location where it is accommodated in notch 10, with an indentation 14 into which one edge of the relevant notch enters with a tight fit; this arrangement improves the stability of the bar, especially when hand-rail 12 is not yet in position.
  • HO. 4 is a part-section, in a horizontal plane on a level with the recess, of a bar arranged in a notch in the top rail (the latter is not sectioned, in order to make the drawing easier to understand), one edge of which enters the recess 14.
  • each bar has a detachable ferrule 15 made of synthetic material which insulates the bar acoustically from the remainder of the structure, thus restricting the propagation of vibrations along the length thereof.
  • the lower end of each bar may also have a detachable ferrule 16 performing a function similar to that of detachable ferrule 15.
  • the bars may be of any desired shape, in which case openings 6 and notches 10 will be adapted to the shape selected; similarly, the shapes of the sections used for the bottom rail, the top rail, and the hand-rail may be different from those illus trated in the drawings, the invention being applicable to rails and hand-rails of all shapes. It is therefore wished to have it understood that the present invention is not limited in interpretation except by the terms of the following claims.
  • a guard-rail comprising: substantially vertical stiffeners', substantially horizontal bottom and top rails attached to said stiffeners; a hand-rail attached to said top rail; and a series of bars, each bar being attached,
  • said top rail including, at the location of each bar, a notch laterally opened to one side thereof and accommodating the upper part of the corresponding bar whereby said bars may be individually mounted by first inserting the lower end thereof in said bottom rail and by subsequently inserting the upper end thereof in their accommodating lateral notches; said hand-rail having a flange closing off said notches after insertion of the bars in the top rail thereby securing said bars therein.
  • each bar is provided, in the part accommodated in the notch in the top rail, an indentation into which one edge of said notch enters.
  • a guard-rail according to claim 1 characterized in that the upper end of each bar is provided with a detachable ferrule made of synthetic material and accommodated in the top rail.
  • a guard-rail according to claim 1 characterized in that the lower end of each bar is provided with a detachable ferrule made of synthetic material and accommodated in the bottom rail.
  • a guard-rail according to claim 1 characterized in that the profile of the top rail has a flange against which the upper ends of the bars rest.
  • a guard-rail according to claim 1 characterized in that the bottom rail has a flange therebeneath upon which the lower ends of the bars rest.
