Description

The invention relates to a door leaf of a sectional or tilt gate, which is in a lateral guide rails, which have a substantially vertical Ab-section and a substantially horizontal portion with arc sections connecting therebetween, and that in the area at least one of the substantially horizontal sections the guide rails Endlagendämpfungseinrichtung is present.

By the DE 75 40 330 U1 is a braking device for overhead doors has become known in which the swing gate brakes soft at the top stop and is held in this position. The braking is achieved by an end stop in conjunction with a leaf spring whose effective spring force is adjustable by a screw.

An attenuator, which is attached to the free end of a belt in one or two catching devices, are the DE 32 06 813 C1 again.

In the DE 20 2005 006 255 U1 a Schwingtor is described which has an energy storage device in the form of a spring buffer at the free end of each track. In an analogous manner, such a spring-loaded buffer is also the LU 90 915 A1 removable.

End position damping devices are well known in the case of gates. They are designed as compression springs so as to be able to perform a damping on impact in a driving into the end position of the opening position door leaf. Such a damping device thus protects the door leaf and the guide rails from damage. Through the use of compression springs, which are guided on a pipe or a rod, this type of construction creates an unreasonable noise nuisance.

The object of the invention is to provide a mechanically operating cushioning for a door leaf, an overhead door designed as a sectional or tilting gate, which is easy to manufacture and usable for different Torgrößen and different types of drives and also largely prevents noise generation during operation.

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

End-position damping devices, with gates that are automated by a drive, are basically there to eliminate the kinetic energy that is present when the door leaf starts up. If this were not carried out, it could come during the opening phase of the door leaf, for example, in a hard stop, to damage the opening mechanism.

In manually operated gates, the door leaf is opened by hand and pushed into its open position. In such a goal, the end position damping device is used as a kind of stop and forms a backup of the door leaf in its open position. Of course, in this application, the end position damping device with its damping device, the door leaf can be brought out of its open position, but there is no storage of Anfahrkräfte instead.

The present invention is operational for both uses. In the following description, however, the automated training will be described.

It is a Endlagendämpfungseinrichtung used according to the invention, which includes a device having a damping element, the design of which is not reduced upon impact of the opening door leaf as in the prior art but is increased. Suitable for this are tension springs or the like, which eliminate the kinetic energy contained in the impact of the door leaf by increasing their length extension and can store at the same time. By using tension springs, the damping travel is not so limited as in compression springs, because compression springs have only a limited damping distance, because the spring travel are blocked by the opposing windings, in such a case no damping effect is given.

In a further preferred embodiment, however, it is also possible that the length extension of the Endlagendämpfungseinrichtung is reduced without the use of a compression spring according to the prior art. These two different approaches can be realized in various ways. A component which is increased by load in its longitudinal extension is, for example, a tension spring element or a shock absorber. Such a tension spring element absorbs the kinetic energy contained in the moving door leaf when the door leaf impinges on the end position damping device and stores it simultaneously.

The damping device is also used in addition to the above-described use to exercise as traction help in the closing operation of the door leaf from the open position support in the form of traction. The recorded within the damping element during the opening process kinetic energy of the door leaf is stored after completion of the opening process in the damping devices as static energy. This is possible because the drive of the door leaf causes a blockage of the door leaf in the open position. At the initiation of the closing process, this blockage is released and at the same time the at least one damping device releases the previously stored energy by generating a starting aid on the door leaf. The damping device presses against the upper end of the door leaf and pushes this, with the aid of the drive, out of the park position. Thereafter, the damping device resumes its basic position and can again store the kinetic energy of the approaching door leaf in the next opening process. Since the Torgrößen turn out to be different sizes, it is possible with the damping device according to the invention, the devices used to easily replace the energy storage, so as to be able to perform a simple adaptation to a variety of Torgrößen. The housing of the damping device always remains the same.

In the end position damping device according to the invention, depending on the size of the door leaf to be moved, the spring characteristic of the door size can be adapted. It is also possible that tension spring elements are used as Duplexfederelemente with two nested tension springs.

In a further preferred embodiment, it is also possible to use mechanical shock absorbers. Furthermore, the end-position damping device may also include an elastic polymer element.

The above-described various devices for cushioning are preferably housed within a housing. These devices can easily perform a translational movement upon impact of the door leaf end and then relax again when returning the door leaf to its normal position. A suitable housing may be round, square or rectangular, depending on the use of the damping element.

While the known in the prior art damping devices have a stop located in front of the head, here again, the invention takes a different route. For this, the housing has an open passage in its longitudinal direction. From the passage, a stop protrudes, which is connected to the device. Such a stop is preferably formed of a hard rubber material or other suitable material on the tread surface of the door leaf.

This design of the end position damping device, it is possible to attach these laterally to the substantially horizontally extending Ab-sections of the guide rails by mounting bracket. This has the particular advantage that depending on a wide variety of door sizes and the Endlagendämpfungseinrichtung can be accurately placed. Furthermore, a light replacement or retrofitting is possible by the chosen construction. This is not possible with known spring buffers, as they are mounted on crossbeams between the horizontal sections of the guide rails.

In a preferred embodiment, the device with the damping element end fasteners. In the housing by a protective tube interconnected guide pieces are present. On the protective tube at the same time the side protruding from the housing stop is attached. In this case, the tension spring element is substantially enveloped by the protective tube in the parking position. The tension spring element is fastened in one of the guide pieces, next to the stationary attachment.

In order to prevent noise generation in this embodiment according to the invention, the housing may be formed inside or outside with a damping material for structure-borne noise reduction. Eben-if the protective tube can be lined with such materials, such as a plastic pipe, inside.

In the damping device according to the invention, the final formation can always be designed differently using the same housing. In a first preferred embodiment, the closure of the housing offers at the end the possibility of simultaneously carrying out the fastening of one end of the tension spring element via the mountings for attachment to a guide rail. Since both ends are made the same with their attachments, it is possible that such end-position damping means can be used on both the right and left side in guide rail assemblies with the same components.

In order to further increase the universality of the end position damping device, it is possible that the housing is equipped with its own end pieces. In this embodiment, the tension spring element is fastened over one of the end pieces. Here it is possible at the same time that the structure-borne sound insulation does not perform directly on the metallic Abschlußstücken, but with the interposition of a rubber element, so as to prevent decoupling of the resulting noise in the operation of Endlagendämpfungseinrichtung. In this embodiment, the housing, including the device for cushioning, be well stocked and thus also with a variety of damping means, and their different strengths, are equipped. This embodiment is attached by the same fastening means on the guide rail or the like. It is understood that this embodiment is also applicable for left and right applications.

The various types of end position damping devices described above with a device designed as a tension spring element or equivalent can find use in overhead doors such as sectional doors and overhead doors, both manual and automated.

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.

In the FIG. 1 a first preferred embodiment of a cushioning device 1 is reproduced in a perspective view. Within a housing 2, the ends by closures 3, 4, is closed, a device is included, which is used for cushioning a moving door leaf. When hitting a stop located outside the housing, the kinetic energy present in the moving door leaf is recorded and stored. While the statements 3 and 4 perform the end of the housing 2 end, can at the same time at the statements 3, 4 by lateral fasteners 29 attachment to not shown, substantially horizontally extending guide rails via an opening 8 done. While in this exemplary embodiment, the housing 2 has been shown as a square housing, of course, other types of shape design, in particular round or rectangular, are also possible.

In the FIG. 2 In the rear view of the end-position damping device 1, the fastenings 29 become visible overall, which serve for connection to guide rails or stationary components. By these fasteners 29, it is for example possible that the Endlagendämpfungseinrichtung 1 does not require any special space and does not make an extended guide rail as in the prior art. The end-of-stroke damping device 1 can be placed below or above the substantially vertical guide sections.

According to the detailed representation of the housing 2 according to FIG. 3 the housing 2 consists essentially of a base 9, of which angled side walls 10 and 11 extend, at the ends of each of which a web 12 is angled such that a partially enclosed space is formed within the housing 2. By the opposing webs 12, an open passage 13 is formed between them, which offers the possibility to connect the stopper 5, for example via a connecting piece 6 with a protective tube 7.

In an enlarged detail view after FIG. 4 the end-side eyelet 28 of a tension element 19 is illustrated with the conclusion 4. In addition to the attachment 29, the conclusion 4 a bend 14, which is provided with openings 18 so that a web 20 is maintained. The web 20 is designed so that it ensures the possibility of attachment via the eyelet 28 for the tension spring element 19. The bend 14 also has stops 17 for connection to the housing 2. When looking through the apertures 18 and the protective tube 7 is visible in addition to the end of the tension spring element 19, which is connected to a guide piece 24. In the area of the stops 17, inwardly bent projections 16, as it were, form a piece connection with the housing 2. When the damping device 1 is fastened to a guide rail via the fastenings 29, a secure hold of the housing 2 with the device is achieved.

The stopper 5 is releasably connected via fastening screws 15 with the connecting piece 6 and thus exchangeably connected. In the presentation of the FIG. 6 the housing 2 has not been shown. While on the left side of the protective tube 7, the guide piece 24 is shown, is on the other end of the protective tube 7, a guide piece 23 has been shown. The guide piece 23 and the guide piece 24 are fixedly connected to the protective tube 7. Characterized in that a tension spring was used in this embodiment, the protective tube 7 is formed round. Both the guide piece 24 and the guide piece 23 can be made inexpensively, for example, from a plastic.

With the protective tube 7, the connecting piece 6 is connected by force and form-fit. The connecting piece 6 has a bend 21, on which the stop 5 is fixed. From the connection piece 6 fixed to the protective tube 7 by a connection 26, the area for fastening the connecting piece 6 via the connection 26 to the protective tube 7 has been enlarged by using a bevel 27.

In the FIG. 7 , in which the device for damping the door leaf has been shown in a rotation, the other end of a possible attachment of the tension spring element 19 can be considered. The tension spring element 19 is there via a spring holder 22 which penetrates the guide piece 23 has been attached. This represents a cost-effective spring holder 22 and allows a quick replacement of the tension spring element, for example, at different Torblattgrößen in production. The storage of Endlagendämpfungseinrichtung is simplified by a multiple.

In the FIG. 5 the device is after FIG. 7 completed by the surrounding housing 2. It is clear that it comes through the longitudinal passage 13 in the housing 2 upon impact of a force on the stopper 5 to a change in location of the protective tube 7 with the guide pieces 23, 24 from the rest position in the translational direction within the housing 2. By applying the force on the stop 5, the tension spring element 19 is pulled apart and can thereby easily absorb the forces of the door leaf occurring in the final phase of the opening process.

In the FIG. 8 a modified type of Endlagendämpfungseinrichtung 1 is shown in a further preferred embodiment. The housing 2 is identical, with only the tension spring element 19 has not been posted on the fortifications 29. Rather, the housing terminations are performed in a form that brings an even easier and more efficient storage or assembly with it. The housing 2 is fastened via fasteners 43 to the substantially horizontal sections of the guide rails or the like. The Tension spring element 19 is equipped on both sides for structure-borne noise reduction with damping measures.

The end-side design of the housing 2 with a closure piece 36 can the FIG. 10 be removed. In this case, the end piece 36 is formed so that it rests against edges of the housing 2 and at the same time has bends 39 which engage in the housing 2. As a result, a secure fit and secure placement of the end pieces 36 are achieved. Against the outer surface of the end piece 36 presses a rubber element 35 whose outer surface is provided with a disc 34. Against the disc 34, a nut 33 is tightened, which is screwed onto a connecting element 32 which is provided with a thread 40.

Through the sectional view to FIG. 11 This embodiment can still be clarified, wherein the connecting element 32 with a lateral clearance and air with respect to the bore 25, the end piece 36 penetrates. The part of the connecting element 32, which dips within the housing 2, has a bore 41, in which preferably an eyelet 38 is hooked into a differently shaped end of the tension spring element 19. The execution of this attachment of the tension spring element 19 is designed so that no contact with parts of the housing 2 can take place, characterized a Körperschallendkopplung is achieved to a large extent. The sectional view after FIG. 11 shows the tension spring element 19 in a loaded or partially loaded position, wherein the individual turns of the tension spring element 19 have been pulled apart. Also, the representation of the FIG. 11 can be taken that the guide piece 42 has left in connection with the protective tube 7, the end position in the region of the end piece 36. By the guide pieces 24, 42, 23 a clean guidance of the protective tube 7 is achieved within the housing 2.

Also the FIG. 10 shows the tension spring element 19 in a partially loaded position, wherein in the longitudinal passage 13 of the housing 2, the connector 6 can come to outside of the housing 2. In the end piece 36 threaded holes 37 are still included, can be introduced via the screw 30. Such a connection shows the FIG. 9 , in which the attachment 43 is made with its angled portion 14 against the end piece 36. The connection between the bend 14 and the end piece 36 is achieved via the screw 30. In order to ensure adjustability here, 14 adjusting holes 31 have been inserted within the bend. So that the structure-borne noise decoupling can also retain its function with attached attachments 43, bores 25 are contained within the bends 14 and are so large that here too the rubber element 35 can pass with play.

The FIG. 12 shows once again in an exploded view the components contained within the housing 2 and how they are functionally connected to the fasteners 43. The protective tube 7 is equipped on the left side with the guide piece 42, wherein on the circumference of the protective tube 7, the connecting piece 6 has been fixed non-positively and positively with the cantilevered stop 5. Within the skirt tube 7, the tension spring element 19 is included. On the right side of the end of the protective tube 7, the spring element 19 protrudes with its eyelet 28. On the eyelet 28, the connecting element 32 has been attached. The guide piece 23 with a bore 25 thus permitted to let the connecting member 32 with all-sided great play pass through and penetrate the rubber member 35 and the disc 34 to be fixed with the nut 33. The fixing takes place against the end piece 36. The end pieces 36 are inserted end into the housing 2 and are attached even with the fasteners 43 on a substantially horizontal extension of a guide rail or the like.

As the preceding description makes clear with a tension spring element 19, contrary to the known embodiments of a stop buffer, a reversal of motion, namely in the form of the tension spring, has been carried out. This can be carried out in an analogous manner with a suitable elastic polymer body or else with a shock absorber. As a result of the application of force to the stop 5, both the tension spring element 19 or else the polymer element or the shock absorber are elongated in their elongation in the longitudinal extent.

The cushioning 1 can also be regarded as a safety device, for example, if the end position of the control of the door fails, or if the force applied to the door leaf manual forces in the open position are too large.
