Abstract

An articulated overhead gate for gate openings with particularly small drop heights between the upper edge of the gate opening that is to be closed and an adjoining overhead area or similar with a gate leaf consisting of several panels (3, 5) articulated successively in the direction of movement, which are driven by laterally arranged rollers (2) in first lateral roller rails (6), connected in an approximately vertical and thereby curved horizontal direction, excepting the upper panel (5) in closed position, which engages with its rollers (4) which, in this position, are arranged in the upper edge area (30), in second roller rails (7). Said roller rails are parallel to and located above the facing horizontal segments of the first roller rails (6), each segment having an end part (8) facing the gate frame, a first section (10) of which part is lowered only slightly in relation to the horizontal, and a second section (11) correspondingly inclining only slightly over 90 DEG to the horizontal in the direction of the ground. The articulated overhead gate is optionally designed, for manual gate-leaf or motor-driver actuation so that the rollers (4) of the upper panels (5) can be optionally arranged in order to be vertically displaceable in relation to their axes, and so that the transition areas (19) between the first and second sections (10, 11) are each optionally provided with a spring element (12, 15, 15') with a non-rigid deflection surface for the suspersion of the roller (4) entering the transition region (19), and for the deflection of the same from one section into the other.

Description

The present invention relates to ceiling-mounted articulated gates for gate openings with a very low height of the lintel installed between the upper edge of the gate opening to be closed and the adjacent ceiling area, which contain a gate web consisting of several successively located in the direction of its movement hinged with connected panels, which are installed with the possibility of movement with the help of rollers located on the sides in the first side guides in an approximately vertical and, thanks to the arc-shaped transition, in a horizontal direction, with the exception of the upper panel in the closed position of the gate, which by its rollers, which are in this position in the area of the upper edge, enters the second guides, which are located parallel to the horizontal sections of the first guides facing them and above them, and which accordingly have, if you look at the gate box, an end section, which with its first section is only slightly inclined relative to the horizontal, and with its second area, respectively, only slightly more than on 90" relative to the horizontal, inclined to the floor. For balancing, such ceiling sectional gates are preferably equipped with a spring device, which is supported by a support inside the space covering the gate opening - as a rule, in the corresponding end zone of the horizontal guides.

The low height of the gate lintel requires the rollers of the top panel to be moved along the guides in such a way that this panel in the closed position of the gate would fit correctly against the leaf, and that, however, the entire door leaf in this closed position would be correctly guided downwards. Therefore, the slight inclination of the second guides for the pair of rollers of the upper panel in the final section towards the gate box cannot be completely abandoned. Since the considered sectional ceiling gate must be able to move between closed and open positions both manually and with the help of, preferably, an electric drive unit, the gate leaf must have different adjustable positions of the upper rollers of the panel, and in the position of the corresponding rollers, shifted downwards relative to the upper panels, to control the gate manually, the gate leaf does not need to be pressed from the outside, and on the other hand, when opening manually, by transferring an approximately vertically directed movement through the handles located on the gate leaf, the transfer of the rollers of the upper panel to the horizontal zone of the guides should be as smooth as possible. In the position shifted to the top of the top panel, to control the operation of the gate with the help of a drive unit that normally works with a traveling carriage moved along linear guides, hinged to the top panel, an unauthorized pressure on the top panel itself from the closed position is prevented by an actuator that, according to stops, while the opening movement starts from the horizontal direction.

Taking into account these circumstances, the final zone of the second guides has a shape that is distinguished by a special course of their trajectories, namely such that, if you look from the horizontal section of the second guides, on the first section, at first only at a small angle, there is a descent, which at an angle , only slightly larger than 90", ends in a second section oriented approximately vertically to the floor.

The end sections of the second guides, which have this shape, can be used without problems to control the operation of the gate with the help of a drive unit, because the movement started from the horizontal can effortlessly draw in the roller pair shifted upwards, which is motionless when the gate leaf is closed, practically in a transition zone between both sections, into the horizontal sections of the second guides, while when the gate leaf is moved to the closed position, the rollers of the upper panel are pushed by the drive unit into the outer corner area of the guide between the sections of the end part.

When controlling the operation of the gate manually, that is, when the force of movement is transmitted through the lower panels of the gate leaf, a difficulty arises, which consists in the fact that only a slight force can be applied to the rollers of the upper panel from the vertically directed lifting movement due to the gentle shape of the first section of the end part of the second guides in the horizontal direction, so that - along with the correspondingly firm stop of these rollers - a significant force threshold must be overcome at the beginning of the opening process. When moving to the closed position, the rollers of the upper panel are rapidly moved to the corner zone between the sections before lowering into the vertical second section, and as a result, when the direction is changed, there is a corresponding impact on the rollers, which causes an unpleasant noise.

For this reason, according to the invention, in the case of manually controlling the operation of the gate, an elastic element protruding into the corner zone, respectively into the trajectory of the rollers of the upper panel, is provided, which has a two-fold task: during the closing movement, the upper roller pair itself is elastically caught when transitioning from of the first section into the second section of the end part of the second guides, due to which the collision with the outer wall of the end part facing the gate box is damped and, accordingly, the noise is reduced. When transitioning from the closed position to the open position of the gate leaf, the change in the direction of movement of the rollers of the upper panel occurs more gently, so that the transition from the vertical second section to the first section, only slightly inclined relative to the horizontal, is carried out, even taking into account the flexibility of the elastic element, along an arc greater radius than the radius of the angular trajectory of the final part between sections; as a result, the above-mentioned high power threshold is significantly reduced.

The elastic element, made in accordance with the best version of the invention in the form of a plate spring, but which, in principle, can also consist of a separate spring between the outer working surface of the end zone and a strip of material imitating the working surface, or from a solid body of elastic material inserted into the corner area of rubber-based material or the like is only necessary for manual gate operation, while it is rather a hindrance for gate operation with the help of a drive unit. For this reason, the elastic element is removable and can only be installed manually. As a result of the application of a driving force to the gate leaf, the rollers shifted upwards for this basically roll mainly on the outer relative to the curvature of the end part of the working surface, while when controlling the operation of the gate manually, the rollers shifted downwards are perceived by the inner working surface relative to this curvature, which is also facilitated by spring system, and as a result the smoothness of the stroke is improved.

Below, the invention is explained in more detail by examples of its implementation with reference to the attached drawings, which show:

Figure 1 shows the ceiling articulated gate of the above type, known in principle from the prior art. Rollers 2 of panels 3, with the exception of rollers 4 of the upper panel 5, move along the first guides 6, rollers 4 - along the second guides 7, as indicated at the beginning. The corner zone marked with a circle in Fig. 1 is schematically depicted on

Fig. 2 in the direction of the upper longitudinal crossbar of the gate frame, schematically reproduced in Fig. 3 on an enlarged scale and schematically shown on a more enlarged scale in Fig. 4 in the same form as in Fig. 2, from the point of view of the functional arrangement when controlling the operation of the gate manually . Fig. 3 shows, in particular, the end part 8 of the second guide 7, namely, according to the best version, in the form of a cast part, in particular, a zinc part obtained by pressure casting, adjacent to the end of the horizontal section 9 of the second guide 7 facing the gate frame. Fig. 4 shows the working surfaces 13, 14 of the guide end element of the end zone of the first section and the second section 11, which extends vertically downwards and which adjoins them almost at a right angle. This figure shows the variant of execution when the elastic element 12 is inserted with the relative roller of the upper panel 5 for moving the gate leaf manually.

Figures 5 - 7 show the end part 8 of the second guide 7 at different positions of the related roller 4 of the upper panel 5 during the transfer of the gate leaf from the open position to the closed position. At the same time, the arrows indicate the adjacency of these rollers 4 to the inner working surface 13 of the end part 8, in Fig. b additionally indicate their effect on the plate spring 15, which, as indicated, is removably fixed on the downwardly oriented end part of the wall 16 of the guide, forming it outer working surface 14. On this end part 8 or on most of its length, in addition to the lower working surface 13 of the guide, also the upper working surface 14 of the guide is equipped with side shelves 17, 18 turned to the side of the roller 4. As indicated by the above-mentioned arrows, the roller 4 interacts with the internal working surface 13 of the end part 8 relative to the overall curvature, and only at the transition 19 between the sections 10, 11, the spring 12, 15 also acts on the roller 4.

Fig. 8 and Fig. 9 show the end part C for the case of moving the gate leaf using the drive unit, and in this case the plate spring 15 is removed. The arrows show that the roller 4 of the upper panel 5 as a result of the otherwise applied force acts on the outer, relative to the general curvature, working surface 14 of the guide. If when controlling the operation of the gate manually - Fig. 5 - 7 - the roller 4, shifted downward relative to the upper panel 5, falls so completely in the closed state into the second section 11 that the roller 4, when an external force is applied to the uppermost panel 5, rests on the lower working surface 13 of the second section 11, when controlling the operation of the gate with the help of the drive unit, the roller 4 due to its upward displacement stops in the transition zone 19 between the sections 10, 11, and the drive unit prevents the movement of the upper panel 5 under the influence of an external force. In manual mode of operation, the gate leaf is blocked in the closed position, when working with a drive unit, this can also happen with the help of a latch 20, which falls, preferably automatically, into the closing position, and which is released by the drive unit at the beginning of the opening movement.

Fig. 10 shows an alternative version of the plate spring 15, which in this case acts on the roller hub, the roller axis or on the sleeve 23 located on it from the side of the guide 7. And this spring 15 is fixed on the side of the gate frame or inside the zone 24 of the gate opening , can also be removed or inserted in the case of controlling the operation of the gate by the drive unit, that is, it is, therefore, installed removable.

The first section 10 of the end part 8 of the second guides, as indicated in Fig. 9, which has a slight inclination to the horizontal to the side of the gate frame, is subdivided again, namely along its length from the horizontal section 9 of the second guide 7, first to a segment 21, inclined at a smaller angle, and then to the segment 22, inclined at a slightly greater angle, so that the angle a" is less than the angle B, i.e. a" r. The segment, preferably the shorter of these two segments 21, 22, located on both sides of the fracture, provides due to its steeper drop, more purposeful transfer of the gate leaf to the closed position.

Fig. 11 - 13 shows an example of an offset assembly of the holder 25 of the rollers 4 of the upper panel 5, namely on

Fig. 11 is a perspective corner view highlighted by a circle in Fig. 1, with an enlarged image of the details, and on

Fig. 12 and

Fig. 13 - both positions of the roller 4 relative to the holder 25, namely with a downward shift for controlling the operation of the gate manually with a spring 12 (Fig. 12) and with an upward shift for controlling the operation of the gate using a drive unit without a spring (Fig. 13). Adjustment is carried out with the help of elongated holes 27 in the bracket 26 of the roller bearing, provided for interaction with screws 28 with a hexagonal head, and the elongated holes 27 in the bracket 26 of the roller bearing are made so that they can be used both on the right and on the left. The holder has a projection 29 directed to the upper edge 30 of the upper panel 5 and which rests on it in the lateral orientation, which allows to relieve the screw fastening of the holder on the inner wall of the upper panel - see also a partial image on a larger scale in Fig. 11.

The spring balancing device is not specified. The corresponding structures are characterized by the fact that they are not located in the zone of the jumper, but are supported inside the room, in particular in the end zone (from the side of the room) of the horizontal sections of the guides, in particular the second guides. In this case, we can be talking about tension helical springs, which are located on the outside of the guides, in particular, those made of two coaxial helical springs with oppositely directed spirals of turns, but a torsion spring shaft of the usual design, fixed behind the guides, can also be provided, if look inside the room.

Spring devices work in relation to their connection with the gate leaf - its lower panel - in a known way by means of cables passed through the rollers; the shaft of the torsion spring also has drums for the cable and works in a known manner, while the helical tension springs, which are located on the outside along the horizontal sections, in particular, of the second guide on their end facing the gate frame, are equipped with a roller, or - in the case provided with considerations of the reliability of the two-cable variant of execution - by appropriate two-groove roller systems that work as a freely mounted roller.
