Definitions

  • This invention relates to structural members for supporting panels, e.g. panes of glass, and has an important application in relation to what are known as patent glazing bars.
  • US-A-2976969 discloses a structural member comprising two elongate elements which are drawn together by screws to grip between the elements the adjacent edges of two panels.
  • FR-A-2455158 discloses a structural member comprising two elongate elements which fit together so as to be capable of gripping between them an edge portion of each of two panels between which the member is disposed, each of which elements comprises, viewed in section at right angles to its length, a channel-section portion having a base and two side walls which side walls extend towards the side walls of the other element for abutment with the faces of the respective panels to grip the panels between them, each of said elements further comprising between said side walls, two parallel limbs projecting towards the other element, and means whereby the two elements can be moved stepwise towards each other to grip the panels between them.
  • the two limbs of each element project into overlapping contact with the respective limbs on the other element, one limb of each element being longer than the other limb and being formed at substantially its free end with a laterally projecting spacer flange.
  • the limbs being capable of a degree of resilient flexing laterally of themselves and the mutually contacting surfaces of the limbs being formed with serrations extending lengthwise of the elements, the serrated surfaces of the two limbs of each element facing in the same direction and the serrations on the longer limb of each element facing away from the shorter limb of the same element, said spacer flange of one element extending to a position adjacent the underrated face of the longer limb of the other element, the serrations operating in conjunction with lateral flexing of the limbs to enable the two elements to be pressed together to grip the edge portions of the panels, the serrations on each limb riding over those on the co-operating limb of the other element, but to hold the elements together when the pressure is removed.
  • the two elements are preferably identical in cross-section.
  • screw means is provided for pulling the elements into gripping engagement with the panels.
  • the screw means may conveniently extend through an aperture in the base of one of the elements and into threaded engagement with the said spacer flange of the other of the elements.
  • the elongate element 10 shown in section is of extruded form and is made for example from aluminium alloy.
  • the element comprises a channel-section portion with a base wall 11 and two side walls 12 and the tips of which are bifurcated to form dovetail grooves 13 for receiving sealing strips.
  • two limbs 14, 15 project from the base wall, one of which is much longer than the other.
  • the shorter limb 14 extends in this instance to about the same height as the side walls 11 of the channel, and the longer limb 15 has at its free end a lateral flange 16 overhanging the base 11 of the channel.
  • the longer limb has on its face further from the shorter limb a band of serrations 17 which extend lengthwise of the element and the shorter limb has a similar band of serrations 18 on its face nearer the longer limb.
  • Two L-section flanges 20 project from the underside of the base to form with the base a groove 21 having undercut side walls.
  • two such elongate elements 10 are fitted together as shown in Figures 2 and 3 and form a patent glazing bar.
  • Sealing strips 22 are located in the dovetail grooves 13 and one of the elements is inverted and its flange 16 is disposed in the gap between the limbs 14, 15 of the other element.
  • the two elements are then pressed together to cause the serrations 17, 18 on the limbs to ride over each other until the sealing strips 22 grip the side margins of two panes of glass 24 ( Figure 2) or double glazing panels 25 ( Figure 3) which are separated by the member.
  • the limbs flex to allow the serrations to ride over each other but when the pressure is released the serrations serve to prevent the elements from separating again.
  • Self-tapping screws 26 may be provided extending with a clearance through a hole in the base 11 of the channel of the inner element into tapping engagement in a hole in the flange 16 of the outer element to apply the final pressure and/or to locate the two elements against relative slipping movement lengthwise of each other.
  • limbs 14, 15 may be of any required length to enable the panels to be gripped between the side walls of the channels.
  • the flanges 16 are of a length to ensure that the co-operating serrations of the shorter limb 14 of one element 10 and the longer limb 15 of the other element 10 can be engaged and disengaged by making the serrations ride over each other, causing resilient lateral flexing of the limbs, and cannot become disengaged by relative lateral movement of the elements.
  • the undercut groove 21 on the outer element may accommodate a capping strip 27, while that on the inner element may conveniently accommodate flanged portions of a series of brackets 29 having laterally extending arms 30 which are formed with screw holes enabling the structural member to be secured to a succession of spaced supporting cross-members 31. So arranged, the glazing bars cannot be separated from the outer side of the assembly and the glass therefore cannot be removed from the outside. This improves the security of the arrangement. The use of identical extrusions assists in reducing production costs.

Claims (4)

1. Un organe structural comprenant une paire d'éléments allongés (10) qui s'ajustent l'un à l'autre de façon à pouvoir saisir entre eux une partie de bord de chacun de deux panneaux (24; 25) entre lesquels est disposé l'organe, chacun de ces éléments comprenant, vue en section à angles droits par rapport à sa longueur, une partie à section en forme de canal comportant une base (11) et deux parois latérales (12), parois latérales qui s'étendent vers les parois latérales de l'autre élément pour venir en butée avec les faces de panneaux respectifs pour saisir entre elles les panneaux, chacun desdits éléments comprenant de plus entre lesdites parois latérales deux branches parallèles (14, 15) en saillie vers l'autre élément et des moyens grâce auxquels les deux éléments peuvent être déplacés progressivement l'un vers l'autre pour saisir entre eux les panneaux, caractérisé en ce que les deux branches (14, 15) de chaque élément forment une saillie telle qu'elle vienne en contact de recouvrement avec les branches respectives de l'autre élément, une branche (15) de chaque élément étant plus longue que l'autre branche (14) et comportant sensiblement à son extémité libre une bride entretoise (16) en saillie latéralement, les branches étant susceptibles d'un degré de flexion élastique latéralement par rapport à elles-mêmes et les surfaces en contact mutuel des branches présentant des dentelures en dents de scie (17, 18) s'étendant sur la longueur des éléments, les surfaces dentelées des deux branches de chaque élément étant tournées dans le même sens et les dentelures de la branche (15) la plus longue de chaque élément tournant le dos à la branche la plus courte (14) du même élément, ladite bride entretoise (16) d'un élément s'étendant jusqu'à une position adjacente à la face non dentelée de la branche la plus longue de l'autre élément, les dentelures (17, 18) fonctionnant en conjonction avec une flexion latérale des branches pour permettre aux deux éléments d'être pressés l'un contre l'autre pour saisir les parties de bord des panneaux, les dentelures de chaque branche franchissant celle de la branche coopérante de l'autre élément, et par contre pour maintenir les éléments assemblés lorsque la pression est relâchée.
