Definitions

  • the invention relates to an arc-shaped sliding gate according to the preamble of claim 1.
  • a known sliding gate (DE-C-957346) is composed of individual plates which are attached to chains at the top and bottom.
  • the upper chain in particular serves as a carrying and pulling strap, i.e. the individual plates have no additional guide or suspension in a guide rail.
  • the sliding gate is driven by sprockets and the chain.
  • This known sliding gate design is only intended for smaller doors, in particular elevator doors, since in the case of longer and heavier panels, the carrying and pull chain, as well as the gears and drive shafts in engagement therewith, would be too heavily loaded by the panel weight. With a wider door, a larger number of support wheels would also be required, since otherwise the door would sag and jam overall. Attaching aligned support wheels to concrete lintels of wide garage doors is complex.
  • the individual plates are attached with mutual spaces (DE-C-957346, Fig. 3) in order to allow a deflection without jamming the plates.
  • the gaps are only partially covered by projections, so that the known sliding door is not sealed when stretched and closed. This may be the case for elevator doors, but sliding gates, especially garage doors, should be tight against rain and dust.
  • the vertical bars are designed as wooden bars which interlock with a tongue and groove profile. On the inside of the arch, these are connected to each other by flexible, elastic steel strips that run horizontally and diagonally across the entire width of the door, with the steel strips being screwed to the individual wooden bars.
  • the door leaf is assembled in the workshop on a mounting frame, and the door leaf is then transported to the construction site in the fully assembled state and installed on the building in question, for example a garage.
  • the door leaves which are often large in area, are rather heavy and extremely bulky, so loading and unloading them and bringing them into the building in question is very laborious. Therefore, it would be desirable to design especially larger gates so that they can be transported to the construction site more easily and are easier to assemble.
  • the invention has for its object to develop a sliding gate of the type mentioned in terms of an improved function, especially when used as a large garage door, and a significant simplification of assembly work and easier transportability to the construction site.
  • the individual rods are suspended from rollers on a support rail bent in a horizontal plane and fastened with a joint chain that also runs horizontally in each case via snap connections, the joint chain running on the inside of the arch.
  • the articulated chain is therefore extremely easy to connect to the individual bars and, for example in the case of a garage, is not visible from the outside and is protected from the weather inside the garage, where a motor drive can also be installed.
  • the articulated chain is expediently arranged in the upper area of the bars.
  • the bars in the arch area describe a larger circle than the link chain when the sliding gate is moved. Since the length of the link chain is constant and the rods are connected to it, a detrimental tensile stress between the rods would occur if the rods were connected in an articulated manner without the possibility of mutual extension. Therefore, the tongue and groove profile characterized in claim 1 is provided, which allows the bars to be shifted without tension even in the arc area, the gate still remaining tight with no gaps between the individual bars. The assembly can also be facilitated by pushing one profile bar after the other onto the already mounted mounting rail and clipping it onto the link chain. For easy transport, it is therefore possible to deliver the individual parts for the sliding gate separately.
  • an easy-to-install sliding gate is provided, which is guided cleanly in the straight and curved area, without gaps and without jamming, the pull chain being quickly and easily concealed on the inside of the sliding gate, without the weight of the Tores weighs down.
  • the rods of the sliding gate interlock with dovetail profiles which allow the bending of the gate in the arc of the displacement path, rods with such profiles are known as roller shutter hollow profile rods, and since this is a mass product, such rods are also for sliding gates inexpensive to buy.
  • the dovetail profiles are used to transfer the train from one profile bar to the other, in the present sliding gate the train is transferred directly from the articulated chain to each profile bar.
  • the hollow Profile bars are therefore usually mounted or the mounting spacing on the link chain selected so that even in the arch area, where the profile bar connection is widened, the dovetail profile does not fit positively in the groove of the next bar.
  • the dovetail profile provides an advantageous safeguard against the profile being pulled apart, for example in the event of (unintentional) jamming of the profile bars on its underside.
  • it is not necessary to have tensile fasteners in the form of steel strips at several points along the gate height or the like to attach to the bars. Rather, it is certainly sufficient to provide only a single articulated chain for the mutual connection of the bars, which absorbs the tensile forces when the gate is moved without impairing the interlocking dovetail profiles of the bars.
  • articulated chains can be used in the same way, in particular in the case of larger door surfaces, to which the rods can expediently be fastened by means of a snap connection.
  • roller shutter hollow profile bars can be delivered individually for transport and plugged together on site with the dovetail connections, or the door can be rolled up for transport in the already plugged-in state.
  • An expedient embodiment of the articulated chain is the subject of claim 3, wherein the bolts of the articulated chain are extended and these interact as parts of a snap connection with corresponding counter elements on the bars.
  • Plastic clips or the like fastened or molded onto the bars are sufficient to attach the gate bars to the bolt extensions of the articulated chain.
  • a door drive does not have to have a separate cable or chain hoist, as was previously the case with gates, but only engages with a pinion in the articulated chain. Where this is necessary, a counter pressure roller can be arranged on the gate side facing away from the drive pinion in order to prevent the gate leaf from escaping from the engagement area of the pinion.
  • foot pieces should also be used at the lower end of the hollow profile bars. These also improve the strength of the hollow profile bars and can be used as firm and resilient guide parts in a lower guide rail.
  • the foot pieces With the features of claim 7, it is possible to design the foot pieces so that they engage with extensions in the guide rail, which is protected inside the door and is not visible from the outside.
  • the foot pieces engage in one another with a hinge joint, the hinge axis being offset toward the inner side of the rods.
  • a path compensation is also possible here through the special choice of the connection profiles.
  • Claim 8 expresses the fact that it is not absolutely necessary to hang up all the bars on the mounting rail, whereby the link chain between bars with castors is then subjected to a slight vertical load.
  • a particularly advantageous embodiment of a sliding gate is achieved with the features of claims 9 and 10.
  • the distance between the hinge axes on the foot pieces or the joint chain pin spacing should be selected so that it has a slight undersize compared to the nominal width dimension (without interlocking profiles). In this way, when the door leaf is stretched or rectilinear, when it is closed, a slight mutual tensioning of the bars is achieved. This means that the door surface is very stable and tight when closed, and since the bars can no longer move due to the tension against each other, they do not rattle even when exposed to wind. In the arch area, on the other hand, the individual rods move slightly apart for jamming-free and tension-free displacement.
  • FIGS. 2 to 6 show more constructive details of an embodiment of a sliding gate according to the invention on the basis of a section of the door leaf comprising two rods.
  • the bars 2 are each designed as hollow profile bars, as are customary for roller shutters or roller shutters, and engage in one another in a form-fitting manner with dovetail profiles 21, 22 which are subject to play.
  • the individual rods 2 are each provided with a head piece 6 or a foot piece 7, which is inserted into the hollow rod profile and is fastened, for example, by pressing, gluing, riveting or screwing.
  • the head piece 6 and the foot piece 7 are expediently made of plastic, and the head piece 6 is provided with molded plastic clips 61, in which the link chain 3 is fastened by snapping the displacement sections of its link pins 31.
  • the link chain 31 is located on the inside of the door leaf.
  • the head piece 6 of at least a part of the rods is designed as a roller carrier for rollers 62 and guide rollers 63, the rollers in the illustrated embodiment based on the principle of curtain rollers on the inwardly bent leg ends 41 of the support and guide rail 4 which is designed as a downwardly open U-profile run while the guide rollers 63 perform the lateral guidance of the rods between the two leg ends 41.
  • the rollers 62 are arranged in pairs on both sides of the head piece, while in each case a guide roller 63 is accommodated in a horizontal recess 64 of the head pieces and interacts with the edge surfaces 42 of the leg ends 41 of the mounting rail.
  • two bores intersecting at right angles are formed in the head piece 6.
  • running and guide rollers can also be arranged in any other way and combined with a correspondingly adapted support and guide rail or separate support and guide rails.
  • the foot piece 7 is fastened in a similar manner to the head piece 6 on the hollow profile bar 2 concerned and has a U-profile 71 which is open at the bottom and which, with the vertical leg 51 of the lower guide rail 5 designed as a simple angle profile, for lateral guidance of the door leaf in the region of Bottom edge of door leaf interacts.
  • a U-profile 71 which is open at the bottom and which, with the vertical leg 51 of the lower guide rail 5 designed as a simple angle profile, for lateral guidance of the door leaf in the region of Bottom edge of door leaf interacts.
  • any other known guide option for example by means of guide rollers in a U-rail, can also be used here as well.
  • foot pieces 7 each engage with connecting profiles 72, 73, which each form a hinge joint and whose hinge axis is roughly in the plane of the inner side of the relevant hollow profile rod 2, i.e. offset from the center of the profile to the inside of the door leaf.
  • the division, i.e. the center distance of these hinge axes of the plastic and therefore somewhat elastic foot piece 7 has a slight undersize compared to the nominal width dimension N, so that the adjacent bars with the door leaf stretched, i.e.
  • a corresponding effect is achieved in the area of the head pieces 6 in that the double pitch of the link chain 3, that is to say the double distance from the link pin 31 thereof, is slightly smaller than the nominal width dimension N of the rods.
  • the sliding gate just described can, after the individual bars 2 are prefabricated, i.e. cut to length and provided with head and foot pieces, can be assembled quickly, for which only pushing together the individual bars 2 with their dovetail profiles 21, 22 and then snapping the joint chain 3 into the respective head piece 6 of the relevant bar 2 is required.
  • the sliding gate construction according to the invention also offers the advantage of a very simple arrangement of a mechanical door drive without annoying cable or chain hoists, in that, as indicated in FIG. 6, a drive motor 8, expediently a geared motor, is more convenient Place is arranged in such a way that a chain sprocket 81 arranged on the drive shaft engages directly in the articulated chain 3 which serves to mutually connect the individual rods 2.
  • a counter pressure roller 9 arranged on the other side of the door leaf prevents the door leaf from being able to move sideways out of the engagement of the pinion 81 with the articulated chain 3.
  • FIG. 7 shows a further embodiment of the invention.
  • the profile of the support and guide rail 4 is modified such that only one leg end 41 bent inwards is present, while on the side of the support and guide rail 4 pointing towards the outside of the door, the support and guide rail 4 is bent downwards so far that the guide roller 63 receives a management area there. Accordingly, there is also only one roller 62 which is attached to the inside of the door. With this design it is advantageously achieved that the door leaf can be moved further outwards in the direction of the lintel due to the omission of the outer (right) guide roller, or the slot between the lintel and the door leaf under the right guide roller 62 (see Fig. 6) does not apply here.
  • FIG. 8 shows a cross section through two hollow profile bars 2 which are inserted into one another, the dovetail hooks 22 shown in FIG. 3 being missing in another embodiment.
  • the tensile force is thus transmitted exclusively through the articulated chain 3 or the foot pieces 7, the power transmission from the articulated chain attached in the upper region down through the rods to the foot pieces 7 both through the fixed snap connection and the inertia through the weight of the profile rods 2 and the 7 foot pieces.
  • the invention has shown an arc-shaped sliding gate which, with simple assembly and transport options, meets all the requirements of a sliding gate for stability, tightness and ease of movement.
