Definitions
- the invention relates to a high-speed, lightweight, U-shaped or folding lifting gate with a flexible curtain made of plastic film, monofilament fabric or similar materials and / or horizontal slats, and anyway essentially vertical lateral guide rails, support frames and a drive device according to the preamble of claim 1.
- an opening created by the customer e.g. an entrance to the factory hall is closed by an arrangement which comprises a winding device which is fastened in the region of the lintel or the building ceiling.
- An electric motor drive as a rule actuates the winding device with the result of the door being opened or closed very quickly.
- the goal is to close the door opening very quickly in order to prevent heat loss or the ingress of dirt and dust.
- the materials for the actual door lock have a mass that should not be underestimated, which must be managed by the drive device including the winding mechanism.
- the acceleration forces that occur when opening and closing the door should also not be underestimated.
- efforts are therefore made to select the lightest possible materials for the curtain or the slats in order to achieve the required closing times with otherwise little effort on the drive side.
- lightweight materials or a film-like curtain is not sufficiently resistant to mechanical damage, which occurs in particular when a vehicle, e.g. a forklift disregards the opening or closing position of the gate and continues its journey.
- the object of the invention is achieved by a high-speed, lightweight roller or folding lifting door according to the features of claim 1, the subclaims comprising at least expedient refinements and developments.
- the curtain and / or the horizontal slats each have at least one wind catch at their lateral ends, which at the latest when they reach the half or full closing position of the door each come into a locking hook or a locking claw, the hooks or claws in the corresponding center and / or lower region of the guide rails or the support frame of the gate are arranged.
- the windscreen safeguards provided at the end of the curtain engage in the aforementioned locking hooks or claws before reaching the closed position, which can be designed as an inlet funnel, as a result of which the flexible and resilient covering gets a secure grip and strength.
- the locking hooks or locking claws are formed only in the lower region of the guide or the support frame in order to stabilize the gate in its closed position
- the measures known per se for deflecting the curtain or the slats can be retained in the event of a crash .
- accidents with moving vehicles only occur if the door moves from its upper position to the closed position or is not yet fully open. In the case of occurring wind loads, however, it is the other way round, ie here the wind load increases with increasing closing position up to a maximum value with complete closure.
- the windscreen safeguards can be configured as knobs or noses which are attached or integrated into the curtain and which run into the respective hooks or claws in order to prevent the curtain or the slats from sliding out under increased load, in particular wind load.
- the knobs or lugs can have a mushroom head shape in order to ensure the desired locking of the gate when the closing position is reached with a corresponding, corresponding hook shape.
- vertically oriented knobs or noses have the additional advantage that when the curtain or the slat sections are wound up, there is a space which causes any moisture present on the surface of the curtain or the slats to dry faster.
- the windscreen safety device has at least one horizontally extending strut connected to the curtain or the slat, which comprises at its lateral ends a crank which engages in each case with a locking hook or a locking claw when the door reaches the closed position.
- This strut can be integrally but also positively connected to the curtain or the slat. It is also possible to integrate the strut in the curtain or to provide a horizontal pocket on the curtain that receives the strut.
- the locking hooks or locking claws can have an inlet slope or an inlet funnel or an inlet cone for receiving the windscreen safety device.
- the funnel or the slope or the cone it is important to ensure with the embodiment of the funnel or the slope or the cone that the door adopts its closed position unhindered and without it becoming one Clamping the curtain or the slats due to the additionally provided wind catcher comes with a hook.
- the locking hooks as mechanically operable claws in order to grasp or release the respective windscreen safety device.
- the mechanically actuated claws are then transferred to a gripping position in relation to the windscreen securing device when the door has reached its fully closed position.
- the windscreen safety device is designed in such a way that a rod-shaped reinforcement is incorporated or attached in the lateral ends of the slats, each of which merges into a lateral extension, at the end of which an offset is provided that is different from the respective one Hook or the respective claw is picked up.
- the rod-shaped reinforcement can also extend across the entire slat width.
- the strut or the rod-shaped reinforcement have limited elastic properties in order to absorb peak loads, in particular wind peak loads.
- the aim here is to ensure that momentarily acting, even dynamic forces are not or not completely transferred to the door guide in order to prevent damage, in particular mechanical deformations.
- the hooks or claws are adjustable at least in the horizontal direction.
- the hooks or claws elastic or flexibly attaching them elastically, so that load peaks, that is to say briefly occurring, in particular wind load forces, can be absorbed and derived.
- at least sections of the curtain or individual slats are provided with a changeable, controlled transparency.
- the non-transparent or translucent state can be changed to a transparent state so that the driver notices in good time whether there are people, other vehicles or objects in front of or behind the entrance.
- Figure 1 - a first embodiment with windscreen security as attached or integrated in the curtain knobs or noses;
- Figure 2 - a second embodiment with a wind guard in the form of flexible, continuous struts
- Figure 3 an embodiment of a lamellar armor with flexible struts and end thickening
- Figure 4 - a schematic representation of a variant of locking hooks in the form of claws
- Figure 5 - a detailed representation of a slat end with elastic windscreen protection.
- the high-speed, lightweight construction U or folding lifting gate shown only schematically in the figures is based on a curtain 1 or slats 2, which can be moved up or down with a drive device, not shown, in order to open or close the door. Adjust the closing position of the gate.
- Lateral guide rails 3 serve to accommodate lateral end sections of the curtain 1 or the slats 2.
- the curtain 1 has wind-catch safeguards in the form of attached or integrated knobs or noses 4 at its lower lateral ends.
- the windscreen safety device shown there comprises at least two horizontally extending struts 6 connected to the curtain 1, which comprise a crank 7 at their lateral ends, each of which engages in a locking hook or a locking claw 5 when the closed position is reached.
- the locking hooks or locking claws 5 can be designed as inlet funnels and there is the possibility of attaching them in an adjustable manner to the guide rails 3 or a support frame.
- the strut 6 can be made both essentially rigid but also provided with partial elasticity. In the latter embodiment, the strut 6 can accommodate wind load peaks, with the result that the risk of damage to the guide rails 3 is reduced.
- FIG. 3 shows an embodiment of a door as a slat armor with a plurality of slats 2, which have a continuous reinforcement 8.
- the reinforcement 8 is accordingly incorporated into the slats 2 or attached there and merges into a lateral extension 9, on the end side of which a crank is provided which is received by the respective hook or claw (FIG. 4).
- FIG. 4 shows one possibility of designing the locking means as mechanically actuable claws 11.
- These claws 11, which for example can have a half-shell shape, are brought into such a position that the crank 10 of the lateral extension 9 of the respective reinforcement 8 is enclosed in order to slide out to prevent and create the desired wind load resistance of the door in the closed position.
- a spring force support 12 of the claws 11 causes the crank 10 of the lateral extension 9 to slide out only when a maximum wind load or force value is reached or exceeded, with the result that irreversible damage to the guide 3 and / or the slats 2 is prevented can be.
- the claws are normally in the closed position and encompass the lateral extension or the crank 10 of the lateral extension 9 when the gate or the respective slats have reached their closed position. If the wind load exceeds a predetermined value determined by the spring force or other mechanical forces act, there is the possibility that the crank 10 slides out of the claws 11 by overcoming the holding force by the spring force support 12. A repair or a restoration of the original state is then easily possible in a less labor-intensive manner by raising the door and then re-transferring it to the closed position.
- FIG. 5 shows a windscreen safety device with an end-side reinforcement of a slat 2, e.g. in the form of a flexible, resilient band 13 which has a holding knob 14 at its free end.
- the flexible band 13 can for example consist of a rubber-elastic material.
