Definitions

  • the invention relates to spacer frames for double glazing of the type specified in the preamble of claim 1.
  • Spacer frames are known in a wide variety of embodiments and are used to keep two insulating glass panes at a distance from one another and to accommodate a hygroscopic agent within the frame rods.
  • Spacer frames of the type mentioned at the outset are used in particular in the renovation of old buildings when it is a matter of retrofitting windows with insulating glass panes, the windows in the old building being designed as wooden lattice windows.
  • Conventional double glazing would change the external appearance of the old building in such a way that the visual character of the old building facade would be lost, which is why the spacer frame with rungs of the type mentioned at the beginning, which are arranged within the frame between the window panes, is used with advantage for these purposes.
  • the finished rung grid is fixed in position within the insulating glass unit in a predetermined position in the spacer frame. This creates a unit between the spacer frame and lattice grille, which is fixed symmetrically in the spacer.
  • connecting elements which connect the outer end faces of the rung to the long side of the frame bars.
  • Different connecting organs have become known for this purpose. It is known, for example in connection with hollow rung profiles from DE-PS 26 37 034, to form the connecting members as plugs which have a collar which serves as an abutment against complete insertion into the profile. An elastic knob is attached to this collar, which is inserted into a hole in the spacer frame. Due to the elastic and resilient effect of the knob, an expansion is required which prevents the respective rung from being pulled out of the bore.
  • the disadvantage here is that holes have to be drilled beforehand at predetermined positions in the spacer frame, which requires a separate work step and requires an exact measurement of the pitch of the lattice grille that is to be inserted into the spacer frame.
  • Another problem is that desiccant escapes from the spacer frame from the previously drilled holes.
  • a lattice made of hollow plastic rungs which can be removably attached in a conventional window frame, and which is placed in front of the glazing of the window frame consisting of a single pane.
  • pins are used which have been firmly inserted into the window frame with their spigot ends prior to the attachment of the rung grid, whereupon the plastic rungs with their holes are placed on the shaft ends of the pins projecting from the frame.
  • the disadvantage here is that the pins have to be inserted dimensionally in the window frame in separate operations, and that the strength of the connection of the rung grille to the window frame leaves something to be desired due to the loose attachment of the rungs.
  • the invention has for its object to provide a spacer frame for double glazing of the type mentioned, which ensures a precise and firm connection of frame and crossbar with easy installation.
  • the connecting members on the frame rod side as knife parts, preferably as flat knife parts and / or as knife parts additional anchoring elements for axially fixing the knife parts in the frame bars.
  • These connecting members can be made very short, which creates the possibility of inserting the complete rung grille into the previously assembled or bent spacer frame with a slight bend in the spacer frame and making an exact positional alignment of the rung grille, whereupon a positive and / or non-positive connection between the rung grid and spacer frame is achieved in that the frame bars are pressed against the adjacent rungs provided with the knife edges, whereby the knife edges, which are preferably provided with pointed ends, penetrate the tubular frame bars, whereby the rung grid is fixed in position in the frame.
  • the spacer frame Since the spacer frame is only pierced with the knife parts from the airtightly sealed interior, the outer surfaces of the spacer frame remain completely gas-tight.
  • the spacer frame can therefore be filled with absorbent beforehand without bores having to be taken into account or closed, and without the absorbent being able to escape before the crossbar is installed.
  • the connecting members are designed as pins inserted into the rungs with pointed ends and barbs. Due to their construction with barbs, these connecting elements can be made very short, which creates the possibility of inserting the complete rung grille into the previously assembled or bent spacer frame with a slight bending of the spacer frame in it, to make an exact positional alignment of the rung grille, whereupon a positive connection between the rung grid and the spacer frame is achieved in that the frame bars are pressed against the adjacent rungs provided with the pin, whereby the pins with their pointed ends penetrate the tubular frame rods. Anchoring against pulling out is brought about by the barb, whereby the lattice grille is fixed in position.
  • the spacer frame Since the spacer frame is only pierced by the pins from the airtightly sealed interior, the outer surfaces of the spacer remain completely gas-tight.
  • the spacer frame can therefore be filled with absorbent beforehand without bores having to be taken into account or closed, and without the absorbent being able to escape before the crossbar is installed.
  • connecting members designed according to the invention can be made relatively small or short, so that the completely assembled rung grille with connecting members can be inserted into the spacer frame, which can be pulled apart to the extent of its inherent elasticity due to the short connecting members.
  • the spacer frame shown in Fig. 1 comprises four identical tubular frame bars 1, 2, 3 and 4 which are connected to each other by means of corner connectors 5, 6, 7 and 8 bent at right angles to one another by the corner connectors in the ends of the hollow frame bars inserted and positively connected to them.
  • a rung cross is arranged, which comprises a continuous rung 9, which runs centrally between the two frame bars 1 and 3 and parallel to them.
  • Vertical to the rung 9, rungs 10, 11 and 12 are provided, which run parallel to the frame bars 2 and 4 and have a uniform distance from one another and to the frame bars 2 and 4.
  • the rungs 10, 11 and 12 are preferably not in one piece but in two pieces and are connected to the cross rung 9 in a manner known per se.
  • a fixed connection of rungs 9 to 12 and frames 1 to 8 is made by means of connecting members 13, which, as best seen in FIGS. 2 and 5, comprise knife parts 14 which protrude from the end face of the respective rung 10, the associated frame rod at the relevant point penetrate and are anchored in it.
  • FIG. 1 an embodiment of a connecting member 13 is shown in the non-installed state.
  • This connecting member 13 is designed as a bent / stamped part and consists of sheet steel.
  • the connecting member 13 comprises a circumferential collar 15, which is adapted to the contour of a rung formed as a hollow profile and carries on its two broad sides knife parts 14 and 14 ', each comprising a tip end 14' 'and are otherwise formed as flat parts, wherein the flat parts run in a plane which runs essentially parallel to the frame shown in FIG. 1.
  • the collar 15 also represents a flat sheet metal part that runs perpendicular to the knife edge planes.
  • a crosspiece 16 extends from the collar 15 and extends between the knife parts 14 and 14 'and is bent outwards from the plane of the drawing.
  • the web 16 is formed laterally with spreading arms 17 and 17 ', which are designed to be non-positively anchored in the side walls of the associated rung hollow profile, in particular in the inwardly projecting beads provided there for manufacturing purposes
  • the connecting element 13 shown in FIGS. 2 to 4 is anchored in a non-positive manner in a rung hollow profile, the collar 15 resting positively on the end face of the rung.
  • the knife parts 14 and 14 'then extend in the longitudinal direction of the rung and the rung is attached to the longitudinally projecting knife parts on a long side of a frame bar, and with the action of force in the direction of the longitudinal axis of the rung, the knife parts 14 and 14 'penetrate the wall of the frame bar until the rung with the web 16 of the connecting member 13 fits snugly on the long side of the frame bar.
  • this connection is carried out for all rungs and frame bars as soon as the crossbar is arranged in the frame, as a result of which the crossbar is fixed in position within the frame.
  • measures for anchoring the knife parts 14 in the frame rods can be taken to prevent the rungs from being pulled out with the connecting members.
  • These measures can include, for example, anchoring members projecting laterally on the knife 14, for example in the form of barbs.
  • an anchoring can be selected, as can be seen in FIG. 5, which shows a modified embodiment of a connecting element, which will be described in more detail below.
  • the connecting member consists of a knife part 14 that serves to anchor the connecting member in the frame rod 1 and from a plug 18 which is firmly inserted into the front side of the rung hollow profile 10 and comprises a collar 19 which rests on the outside of the frame rod 1 and as Wi derlager serves for the connecting element against insertion into the hollow rung profile 10.
  • the rung-side section of the connecting member can also be designed in any other way.
  • both parts of the connecting member can in turn be designed as a one-piece bent / standing part made of sheet metal.
  • the knife part 14 (in turn, two knife parts 14 and 14 ′ spaced apart from one another can be provided, as shown in FIG 2 to 4)) is divided in the fork part plane.
  • the flat knife 14 accordingly comprises a slot 20 extending in the direction of its longitudinal axis, which divides the knife 14 in the longitudinal direction and extends from the shaft end 21 of the knife 14 to the tip end of the knife 14, so that the fork-shaped knife 14 has two tip ends, each of which a cutting edge 22 and 23 belongs, which lie on the outside of the knife 14 and run obliquely towards one another towards the front.
  • oblique edges 24 and 25 are formed, which run towards each other towards the shaft part 21 and come into contact with the wall sections cut open and bent inwards when the wall of the frame rod 1 is pierced, the Collar 19 comes to rest on the outside of the frame bar 1, so that a positive and non-positive connection of the rung and frame bar is achieved.
  • the fork-shaped design of the knife 14 has the advantage during the piercing process that the two fork-shaped parts of the knife are pushed towards one another, so that the insertion process is facilitated, a non-positive connection with the wall parts 26 and 27 being achieved when the fork arms of the knife 14 spring back , the counter bearing for this connection being created by the collar 19.
  • the spacer frame shown in Fig. 6 comprises four identical tubular frame bars 101, 102, 103 and 104 which are connected to each other by means of right-angled corner connectors 105, 106, 107 and 108 to form a frame by the corner connectors in the ends of the hollow frame bars inserted and positively connected to them.
  • a rung cross Arranged in the frame 101 to 108 is a rung cross which comprises a continuous rung 109 which runs centrally between the two frame bars 101 and 103 and parallel to them.
  • rungs 110, 111 and 112 which run parallel to the frame bars 102 and 104 and are evenly spaced from one another and from the frame bars 102 and 104.
  • the rungs 110, 111 and 112 are preferably not in one piece but rather in two pieces and are connected to the cross rung 109 in a manner known per se.
  • a positionally fixed connection of rungs 109 to 112 and frame 101 to 108 takes place by means of connecting elements, which, as can best be seen from FIGS. 7 and 10, are designed as pins 113 with pointed ends 114, shaft 115 and barbs 115 ', which in the transition area between the pointed end 114 and shaft 115 is arranged and protrudes laterally from the pin 113, with its hook end pointing in the opposite direction to the tip end 114.
  • each stopper 116 comprises a collar 118 on the end face, which serves as an abutment against insertion into the respective hollow rung profile.
  • FIGS. 7 to 9 show a connection point between the cross bar and the frame, the hollow bar profile being omitted for better clarity; that is, only a section of the hollow frame profile 101 is shown, to which the plug 116 is placed with its collar 118, and the pin 113 is firmly anchored in the plug 116.
  • a hole is made in the solid material of the plug 116, and an additional adhesive point serves to ensure that the pin 113 inserted into this hole with its shaft part 115 is firmly anchored in the plug 116.
  • the attachment of the pin 113 in the stopper 116 and its assembly within a rung end section has already been carried out beforehand, and FIGS.
  • the assembly of the spacer frame shown in Fig. 6 runs so that the prefabricated rung cross 109 to 112 is inserted into the prefabricated frame 101 to 108, the frame rods being elastically slightly bent outwards for this purpose to create space for the pins 113 protruding from the end faces of the rung.
  • the frame bars are pressed against the rungs at the points opposite them, as a result of which pins 113 penetrate the relatively thin material of the hollow frame profiles and the skin of the hollow profiles at these points reach behind their barbs, whereby a stable positional fixation of the cross bars is achieved within the frame.
  • the pin 113 is preferably inserted centrally in the stopper 116 and thus centrally in the end face of the rung.
