Definitions

  • the invention relates to a door leaf, in particular an overhead overhead door, consisting of a series of consecutively arranged, articulated panels, the at least one of which is designed as a single- or double-skin slat made of transparent material and inserted into the row of the other slats made of opaque shell material is.
  • Such a door leaf made of uniformly designed slats is known for example from GB-A-2.155.527.
  • the need for perspectives has hitherto been met by cutting window-like openings into slats made of opaque material, for example steel sheet with and without insulating filling, and providing them with a frame containing an artificial glass window pane, or slats articulated to one another in the form of frame structures used, in whose frame fields transparent or only translucent, ie frosted glass-like or "semitransparent" transparent pane structures were used by other configuration or additions; it is also known in this connection to make part of the panels of the door leaf between the connections to the respective neighboring door leaf translucent or to produce them entirely from translucent material (US Pat. No. 1,983,098; DE-A-31.02.897).
  • the invention has for its object to provide a door leaf of the type mentioned that the connection between different slats are as simple as possible with free design of the entire door leaf formation with translucent door leaf zones, taking into account the temperature influences.
  • This object is achieved by the use of individual hinges spaced apart from one another in the joint axis direction, all of which, except for one, permit a displacement movement of lamella sections in the lamella width direction under the influence of heat, in different ways, namely on the one hand through a corresponding axial play between the interlocking hinge tabs of the individual hinges except for one or by arranging the hinge lugs, which produce the connection to a lamella made of transparent shell material, in such a way that a metal rail is inserted in the adjacent edge region of this latter lamella, on which the hinge lobes are fixed such that they are seen in the hinge axis direction engage in wider openings in the slat than the hinge lugs themselves are wide. Both measures can be combined.
  • Hinges are designed with an axial play between the hinge tabs that is dimensioned according to the different temperature expansion behavior of the shell materials between two lamellas, so that the fastening points of the hinge tabs on the one lamella on the one hand and the other lamella on the other hand can shift relative to one another in the hinge axis direction.
  • one of the hinges in particular in the central area of the slat seen in the direction of the hinge axis, is designed with little play in the axial direction, so that a positional alignment of the slats, in particular in their central area, over this Hinge is done.
  • Such an embodiment which is subject to play in the axial direction and thus permits a displacement of the hinge tabs to be applied to the slats to be connected in each case, at least all but one of the hinges is always of importance if by means of a such hinge connection slats made of shell materials of different temperature expansion should be hinged together;
  • this hinge design is not tied to the use of one or more slats made of transparent material, but of independent importance.
  • a lamella made of transparent shell material with a metal body insert, in particular a rail, for example made of aluminum, on which the associated hinge tabs are fixed.
  • a metal body insert for example made of aluminum
  • there are three different temperature expansions namely that of the opaque lamella, for example sheet steel lamella, that of the aluminum rod and that of the transparent material of the transparent lamella connected to the aforementioned lamella.
  • the metal rod from the same material or a material with approximately the same coefficient of thermal expansion as the connected lamella made of opaque material, for example steel in both cases. Then one could do without the axial hinge play and only provide that between the transparent slat profile and the metal rod inserted into it.
  • the hinge connection with play it is advantageous, in particular in the middle region, to provide an adaptation free of play between the hinge flap and the opening in the transparent shell profile which receives it.
  • This central region then works as an axial fixed bearing, while the other passage openings have an axial play relative to the hinge lugs accommodated in them, which could be called a floating bearing.
  • Figure 1 shows a door leaf generally designated 1, which is shown in the closed position 2 with solid lines, while the dashed representation of the door leaf or the slats almost reveals the open position 3 of the door leaf.
  • the lamella which is approximately at eye level in the closed position and is made of transparent plastic, is provided with 4 lamellae, the remaining lamellae, above and below, are made of two sheet steel shells with an insulating foam filling are trained, bear the designation 4 '.
  • rollers 5 are provided on these, which engage in guide rails 6, as is generally known for gates of this type.
  • the guide rails are composed of a vertically running rectilinear section for taking the closed position of the door leaf, an arcuate transition section and an approximately horizontally rectilinear section for receiving the door leaf in the open position.
  • a separate horizontal guide with an inclined transition piece 6 ' is provided in order to transfer the uppermost slat into the closed position at a low lintel height, as can be seen in FIG.
  • the door leaf forms an outside facing outside and an inside facing inside the room to be locked.
  • the extruded shell profile 8 shown in the front view of an embodiment of a lamella 4 made of translucent plastic or, in this case, corresponding to the arrangement at eye level as a window made of clear glass-like plastic, has an outer shell 9 and one facing away from it and the inside of the inner shell 10 facing the door leaf 1 to be closed Mistake.
  • These two shell parts 9 and 10 are perpendicular to it and extend in the horizontal direction
  • Intermediate webs 11 are integrally connected to one another and delimit between themselves and the webs 11 profile chambers 12, which can be closed with the aid of covers 29 — figures 3 and 4 — to be attached to the narrow end faces of the profile 8.
  • the outer shell 9 is interrupted by beads 13 which run horizontally in the profile direction, that is to say horizontally in the state of use, which also appear in a similar form between the slats articulated to one another.
  • the side walls of the beads 13 merge into correspondingly arranged intermediate webs 11 or are formed by these.
  • a holder 17 is formed above the intermediate web 11 which delimits the uppermost chamber 12 upwards and is shaped in the manner of an undercut groove extending in the longitudinal direction of the profile.
  • This holder 17 for an upwardly protruding sealing bead connects to the outer shell 9 and is formed next to a profile cavity 26, the inward end wall of which is flush with the inner shell 10.
  • an aluminum rod 25 is inserted, which extends over the entire horizontal width of the profile and serves to hold the hinges 19, as was indicated by the inner hinge flap 21.
  • a further profile cavity 26 is also formed in the lower front broad side region 16 or in alignment with the inner shell 10, which in the same way serves to accommodate an aluminum rod 25, so that the hinge tabs are fastened in the upper and lower broad side region the lamella is the same.
  • Another fastening alternative was shown in FIG. 2 only for demonstration purposes, namely with the aid of a sleeve screw 24 which is guided through the profile thickness and whose sleeve length limiting the screw path is selected such that when the screw is tightened only a relatively small pressure on the shells 9 and 10 is exercised. In this way, the hinge flaps are fixed directly to the profile without running the risk that the profile will be destroyed by appropriate tightening of the screws.
  • the profile can be made of a clear glass-like plastic such as polycarbonate, plexiglass or the like with a smooth or structured surface, however, it can also be made available in translucent white or in various colors if a window-like view is not to be provided.
  • crystal-clear window areas can remain, in particular due to mechanical surface treatment of the shell parts, while the shell surfaces lying around them are only translucent like frosted glass; this can be achieved, for example, by producing the lamella from crystal-clear plastic, then covering or masking off the window areas and then sandblasting or the like.
  • Figure 3 is a width view of the hinge area between two slats, the upper 4 'in the illustration is formed as a double-skin sheet metal lamella with insulating filling, while the lower lamella 4 in the illustration consists of transparent or clear glass-like plastic and with respect to the hinge flap attachment with the aforementioned sleeve screws is working.
  • the hinges 19 are designed as a “floating bearing” in such a way that there is a possibility of displacement between the hinge tabs 20 and 21 in the direction of the hinge axis 22.
  • Average temperatures are assumed here, so there can be a shift in one direction in the direction of lower temperature and a shift in the other direction of the hinge axis in the direction of higher temperature.
  • this is achieved in that the hinge flaps 20 are fork-shaped with a correspondingly wide fork spacing, while the pivoting part of the hinge flap 21, which engages in the fork of the hinge flap 20, is substantially narrower than this.
  • the hinge 19 'arranged in the hinge axis direction in the central width region of the slats is designed as a "fixed bearing", ie the bearing play described in connection with the other hinges 19 is not present there or by spacers 23 prevented, which are arranged on both sides of the hinge part of the hinge flap 21 between the latter and the fork configurations of the hinge flap 20, as shown in FIGS. 3 to 5.
  • the use of these spacer sleeves 23 enables all hinge tabs to be designed identically, which is of advantage in terms of production technology. Of course, one could also use one with regard to the hinge 19 ', which works in a known manner practically without play in the axial direction between the hinge tabs.
  • the clear glass-like lamella 4 is designed as shown in the profile illustration according to FIG. 2.
  • aluminum rods 25 are provided which are inserted into profile cavities 26, as shown in FIG. 2.
  • the hinge tabs could be placed on the inner shell 10 from the outside and screwed into the metal rail 25 through the plastic. That would be especially the case possible that plastic and metal rails have approximately the same coefficient of thermal expansion, but this should not be the case in principle. Then you would have to make elongated holes in the plastic in the area of the fastening screws. Another solution is shown in FIG.
  • hinges 19 and 19' are used, as described in connection with Figure 3 and explained with regard to their function.
  • the lower lamella 4 ⁇ is not designed as a shell profile like the others, but instead has a frame 30, for example made of aluminum, which - optionally with a number of subdivisions - is clear glass-like or semi-transparent, in basic possibility but also opaque panes.
  • the aluminum frame is connected by means of hinges 19 and 19 'directly to the sheet steel plate 4', so that there are similar conditions as in connection with the connection between the sheet steel plate 4 'and the aluminum rod 25 of the plate 4 in Figure 4.
