Description

The invention relates to a sensory device having at least one sensor which comprises a transmitting and receiving device for securing the closing edge of a door leaf, which is formed of a plurality of mutually hingedly connected elements.

The DE 10 2010 000 234 B3 describes a sectional door with individual, mutually pivotally connected section elements, which are guided and moved in laterally arranged rails by means of rollers. A storable, non-contact sensor in the form of a sensory device for detecting objects or persons in the region of the movement path of the section elements is provided on the sectional door leaf in such a way that a holder is provided which is in a space between the running rail and a lateral section element edge is placed. This holder is moved over roller elements, which are also guided within the track.

The object of the invention is to improve the sensory device to the effect that a greater positional accuracy is achieved during the mobility of the door leaf. Furthermore, this sensory device should be easy to assemble.

The solution of the invention is achieved with the features of claim 1. The dependent claims provide a further embodiment of the inventive concept again.

The sensory device is equipped with at least one transmitting and receiving device for securing the closing edge of a sectional door, spiral door or another type of door. The device is placed between at least one vertical edge, preferably on both vertical edges of the lower element of a door leaf and the laterally thereto, substantially vertically aligned, fixed guide rails. About a connection is the sensory device connected to the lowermost element of the door leaf so that rotational movements and vertical movements are possible. Such a connection ensures that the device can work safely and thus can ensure an accurate protection of the area below the element edge, namely the main closing edge of the door leaf. Furthermore, existing tolerances resulting from the installation of such a door leaf can be compensated by the special mounting method and the structure of the device.

The assembly of the sensory device is pivotally connected to a base element. This basic element is equipped with a displaceable in the translational direction unit and can be moved by rolling within guide rails. In order to stabilize the bearing within guide rails, the sensory device for stable positional compliance has an arrangement of three rollers. These rollers are mounted substantially in vertical alignment with each other on the unit. By this vertical arrangement, the placement of the rollers is carried out so that no common vertical line is assigned to the three rollers with their axes, it creates a kind of three-point storage.

In a preferred embodiment, moreover, the lowermost of the three rollers on the unit is provided with a non-rigid axle. Such an axis is rotatable and thereby changeable at least in another direction. Such an embodiment can be achieved by an eccentric holder which is subject to error. The mobility facilitates insertion into the lateral guide rails, because during rotation the lower axle bearing can be brought out of its position of use.

In a further preferred embodiment, it is possible that additionally or exclusively, the middle of the roll is provided with a device which allows, for mounting in the guide rail, this middle roll is brought out of its use position. This can be done for example by an adjustment of the axis. In this case, provided with an eccentric bearing arrangement of the middle roller is brought out of the position of use. After installation of the sensory device within the lateral guide the storage of the middle roller is returned to its position of use and fixed there.

In addition to the different placements, the arrangement of the rollers on a further change compared to the usual fortifications of roles. This is, for example, that the top two rollers on a fixed axis at an equal distance a roller base on which these axles are mounted. In addition, at the lower roller mounted by the eccentric support, a greater distance from the roller base has been carried out. This special storage of the three rollers an even more efficient stability of the sensory devices in the course of their vertical movements in a drive of the door leaf from the closed position is reached in an open position and back. This is due to the fact that when using guide rails which have a cross-sectionally a J-profile or even a C-profile, the three-point bearing, the sensory device assumes a stable position. The spring-loaded roller ensures in any case that the rollers in the profile of the guide rails exert a sufficient pressure on the inner walls of the profile. By choosing the role placement on top of each other is always ensured that the rollers are in contact with the inner sides of the guide rails. Although the sensory device is vertically adjustable, the choice of roller bearings achieves an extremely stable condition. This is always safe even with curves, as it is given for example between the substantially vertical and substantially horizontal extension of the guide rails. This constant contact is also increased by the fact that the lower arranged on the eccentric mounting movable roller opposite the rollers placed above has a further distance from the roller base. As a result, this role is always pressed into the guide rail, so that a blurring of the sensory device in the process of the door leaf can not occur. For mounting it is possible to place the middle roller on an eccentrically mounted, adjustable axle. After assembly, the roller is fixed again with its chosen distance to the other rollers.

Such a trained sensory device is also suitable, for example, in high-speed spiral doors, which may be similar in their Tor-sheet the sectional doors, without problems to be applied.

The attachment of the three superimposed rollers is performed on a moving unit. This unit is arranged displaceably in a section of the base element. This displaceable arrangement is loaded by at least one spring element, so that upon impact of the sensory device on an obstacle, or the floor, the sensory device is virtually displaced laterally into the space between the element and the guide rail within the base element. During the opening process, due to the spring load, the sensory device is automatically pushed out of its "parking position" again.

Further advantages, features and possible applications of the present invention will become apparent from the following description in conjunction with the embodiments illustrated in the drawings.

The FIG. 1 shows, in a perspective view, a sensory device 1, which consists essentially of a base element 3, which has a vertically variable in the base member 3 unit 10 with rollers 8, 9, 11. The vertical variability within the base element 3 is achieved by an incision 6 present in the unit 10. At the lower foot of the sensory device 1, a sensor holder 5 is fixed, which has at least one sensor 2, wherein the sensor 2 always comprises a transmitting and receiving device. Such a sensor 2 may be formed, for example, as a light barrier or infrared or radar device. On the movable unit 10, the rollers 8, 9, 11 have been arranged on a holder 7 in a substantially vertical arrangement one above the other. The sensory device 1 is connected via a connecting pin 27 with a panel element at its vertical edges and secured by a screw 4.

By the representation after FIG. 2 It is clear that the placement of the rollers 8, 9 and 11 one above the other, in each case in different positions to each other, was carried out via axes 12, 13, 14. Thus, on the left side above the base element 3, the roller 8 and the roller 11 protrude, while the middle roller 9 projects beyond the edge of the base element 3. In this preferred embodiment, the roller 8 on a stationary axis 12, as well as the roller 9 with the axis 13, rotatably mounted. On the storage of the roller 11 with the axis 14 will be discussed separately below.

By the FIG. 3 It is clear that the entire sensory device 1 is connected by the connecting mandrel 27 with the lower element of the door leaf so that in the vertical direction mobility and rotatability is possible, the fuse is made by the screw 4, which is fixed to the holder 7 , With the holder 7, a roller base 25 is further connected, on the rollers 8, 9 can be fixed directly and the rollers 11 via an eccentric bracket 31, wherein at least the roller 11 can be mounted at a distance 26 from the roller base 25.

In the rear view of the sensory device 1 in the FIG. 4 it is clear that the holder 7 is made wider than the incision 6. Thus, the holder 7 is arranged on the roller base 25 distanced to the intermediate element 3 therebetween. On the base member 3 is also a connector 15 for electrical connection via a cable 16 for the sensors 2 is present. Furthermore, an arrangement of at least one, preferably two spring elements 28 has been shown on the back, which are formed as tension springs. In this case, the spring elements 28 are fastened on the one hand in the base element 3 and on the other hand on the movable holder 7. Thus, when pushing up the base element 3, ie, during a closing operation of the door leaf, the fixed support 7 will remain standing by the connecting mandrel 27. The base element 3 approaches the lower horizontal edge of the gate element, so that the sensor holder 5 unlocks to the lower edge of the level forth, the door leaf is then in its closed position over. During the subsequent opening operation of the door leaf, the sensor holder 5 again comes out of the retracted position and as soon as the sensors 2 with the sensor holder 5 no longer have traction, the holder 7 in the in FIG. 4 shown basic position, withdrawn.

In the FIG. 5 It is clear from the perspective view that the movable unit 10 consists of the holder 7 and the roller base 25 placed above and connected to it. In order to ensure the vertical displaceability in the recess 6 of the base element 3, the holder 7 has longitudinal guides 17, 18 extending in the longitudinal direction. The roller base 25 is connected to the bracket 7 by screw members, not shown. By such a structure, a pre-assembly of the unit 10 is much easier to perform.

In the presentation of the FIG. 6 Once again, the formation of the guides 17, 18 below a projecting upper part of the holder 7 becomes clear. Left next to the spring elements 28 are embedded in spring receptacles 20. In addition to the spring elements 28 is in the form of a depression a cable guide 21. When looking at the right side, the different placement of the rollers 8, 9 and 11 with each other clearly. While the front roller 8 are arranged with the roller 9 arranged behind it at the same height to the roller base 25, the roller 11 protrudes beyond the right edge of the rollers 8 and 9. Behind the roller 8, part of the roller 9 is visible in the upper part of the illustration. In this representation, virtually a three-point bearing of the rollers 8, 9, 11 to each other clarified. This type of storage means that there is always a secure, stable hold within lateral guide rails, because the rollers 8, 9, 11 are always in contact with the inner wall of the guide rail.

This particular placement can be especially the FIG. 8 be removed. The axis 12, for the upper roller 8, for example, is placed so that its diameter reaches up to an edge 45 of the roller base 25. In contrast, the axis 13, arranged for the roller 9, quasi-centered on the roller base 25, thereby, instead of the rigid axle for mounting and an adjustable mounting according to a preferred embodiment according to the FIGS. 12 to 16 can be selected, which is set after installation. In the left part of the FIG. 8 a receptacle 35 has been shown for the eccentric bracket 31. At the substantially circular formation of a receptacle 35, a recess 36 and an opening 34 have been incorporated. By this material removal, it is possible to easily mount the eccentric bracket 31. Furthermore, it is clear from this illustration that the center of the receptacle 35 has not been arranged in the middle of the roller base 25, but has also been moved to the edge 45.

In the FIG. 7 the roller base 25 is viewed from the rear side. In this case, the roller 9 has been attached via a screw 37 with its axis 13 to the roller base 25. The roller 11 is equipped with the eccentric holder 31, which was inserted within the receptacle 35. In this case, the eccentric holder 31 has a projection 30 and a projection 33 which are different in their dimensions and dimensioned so that they can pass through the receptacle 35 and the opening 34 and can be rotated after insertion relative to the roller base 25.

By the side view after FIG. 11 showing the lower part of the roller base 25, the use of the eccentric bracket 31 within the roller base 25 is clarified. Within the eccentric holder 31 is a spring 29, which allows a rotational movement. By this rotational movement, the absolute position of the roller 11 is changed to the fixed rollers 8, 9. This change in position facilitates the insertion of the sensory device 1 into the track rail. After the sensory device 1 with the rollers 8, 9, 11 immersed in the track, the subsequently released restoring forces of the spring 29 will perform a reset of the roller 11 to its original position. The sensory device 1 is then securely inserted into the guide rail due to the three-point bearing of the rollers 8, 9, 11. The spring 29 is placed on a spring bearing 42 and fixed with a projection 46 within a bore 44. The spring 29 is thereby formed as a torsion spring and can due to the eccentric bracket 31 after FIG. 10 a rotational movement of the roller 11, which is mounted on a running surface 32 of the axle 14, cause. In this case, the spring 29 is inserted in a middle part 41 and fixed in the bore 44. Subsequent to the running surface 32, a projection 38 is formed, which allows the roller 11 a corresponding space for this rotational movement. The spring 29 dives partially in the eccentric bracket 31 a. The eccentricity of the eccentric bracket 31 is particularly in the consideration of a roller shaft 39, which passes centrally through the axis 14 and a thereto distanced shoulder axis 40, which goes through the spring bearing 42, illustrated. The connection between the attachment axis 40 with the projection 46 and the roller axis 39 is achieved by the molded-in central part 41. By the offset of the approach axis 40 to the roller axis 39, the eccentricity is determined. The eccentric holder 31 is designed, for example, as a die-cast part.

In the FIG. 9 the back of the holder 7 is shown again in a single representation. Within the spring receivers 20, the spring elements 28 are embedded and the other end via holes 24 and screw connected to the bracket 7. It also becomes clear from this illustration that the center axes for the axles 12, 13, 14 are not located on a common reference plane in the longitudinal extent of the holder 7. The axes 12, 13, 14 are carried out in a roller bearing 22 and a roller bearing 23 and in a receptacle 19 via the eccentric bracket 31. The previously free end of the spring 29 is fixed in a bore 43 within the holder 7. Such a design of the holder 7 may be made of injection molding or plastic.

The Figures 12 and 13 give a modified version of the movable unit 10 with a holder 47 again. This is essentially the storage of the roller 9, which can be rotated for mounting from its working position via a capping piece 51 of a setting 48 so that the rollers 8, 9, 11 are virtually on a common reference line, ie that the role of the 9th thereby according to the illustration FIG. 13 is moved to the left. After the insertion into the guide rail, this displacement of the roller bearing of the roller 9 is guided back again, in which the end piece 51, which is guided within a pivoting range recess 63 within the movable unit 10, turned back and then fixed by a fastening 50. In order to be able to carry out this rotation of the bearing of the roller 9, reference is made to an embodiment of the adjusting device 48 FIG. 14 directed. In this case, the adjusting device 48 consists essentially of a connecting piece 64 and the end piece 51. Basically, the connecting piece 64 and the end piece 51 are individual components, which have an eccentric lying Tapped hole 60 and a screw 57 are connected together. The threaded hole 60 is present in a projection 52, which adjoins a round lug 56. The other end of the projection 56 forms a tab 59 of the end piece 51. Within the flap 59 is a bore 58 which is penetrated by the attachment 50 and fixed within the roller base 25. Subsequent to the tab 59 is a projecting collar 54 with a tool connection 55, which serves to adjust the tab 59 in a pivoting area recess 63. The connecting piece 64 is a rotary part which includes a bearing 49 for the roller 9, wherein the diameter of the bearing 49 and the projection 56 are equal. Centrally within the connector 64 is a bore which is penetrated by the screw 57. The outer end of the connecting piece 64 also forms a collar 53. On the other hand, the connecting piece 64 is provided with a recess 61. The recess 61 has been made dimensionally on the projection 52 with its spaced-apart sliding surfaces 62. This type of construction of the adjusting device 48 can in particular the exploded views according to FIG. 15 and 16 be removed. Due to the eccentric threaded bore 60, it is thus possible that the bearing 49 of the roller 9 can be brought from its position of use in a mounting position and back.
