Description

The invention relates to a device for actuating a tilting gate.

Such a tilt gate, which is used in particular for garages, typically has a door leaf with laterally mounted guide rollers. The guide rollers are guided in vertical guide rails, which laterally delimit a door opening, which can be closed with the door leaf.

For actuating the tilting gate, that is to close and open it, a drive unit is provided, which is movable along a drive rail. The drive rail extends in the horizontal direction in the direction of movement of the door leaf and is arranged above the door opening.

For coupling the drive unit to the door leaf, it is known to use linkage that couple the door leaf with the drive unit. It is in known tilt gate systems, such as from EP 0 065 611 B1 . GB 2 124 296 A and DE 39 20 598 A1 known, the linkage always formed in several parts, to be able to pretend the trajectory of the door leaf during the opening and closing movement. In this case, the linkage typically has a curved rod attached to the door leaf, which is coupled via one or more further rods articulated to the drive unit. An actuator of a tilt gate, which has the features of the preamble of claim 1, is made of EP-A-0299489 known.

The disadvantage here is on the one hand, the high design effort that is necessary for the coupling of the door leaf to the drive unit. In addition, the assembly effort is very complex and complicated, which often means that the assembly is not carried out properly and thus the operation of the tilt gate does not work properly.

Another major disadvantage of such systems is that the curved bar attached to the inside of the door leaf has a considerable height. The door leaf is in its open position, in which this is above the door opening in the horizontal direction, so the curve bar protrudes down over the door leaf and protrudes into the door opening, which means that no longer the entire door opening for a retracting vehicle is available.

The invention has for its object to provide a device by means of which a tilt gate is reliably actuated, the device itself can be mounted easily and compactly.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

The device according to the invention serves to actuate a tilting gate which has a door leaf, by means of which a door opening can be closed and which is guided laterally with guide rollers in guide rails. The device comprises a drive unit which is movably arranged in a drive rail running above the door opening in the direction of movement of the door leaf and which is mechanically coupled to the door leaf. For coupling to the door leaf, only one integrally formed actuating rod is provided, one end of the actuating rod articulated to the drive unit and the second end of the actuating rod articulated to an insert which is guided in a running on the inside of the door in the direction of movement of the door leaf rail, is coupled. The insert in the rail is slidable between two end stops. The actuating rod has a segment which can be guided against an abutment on the door leaf when the drive unit is approaching from an open position of the door leaf, as a result of which the upper end of the door leaf can be raised.

The device according to the invention can be mounted easily and quickly. In this case, it is particularly advantageous that for the production of an articulated coupling of the drive unit to the door leaf only an integrally formed actuating rod and thus no multi-part linkage is needed. Due to the articulated coupling of the actuating rod to the sliding insert in the rail, the movement curve of the means of the drive unit to be moved door leaf can be easily specified. It is particularly advantageous here that the device with the actuating rod and the associated insert displaceably mounted in the rail can be adapted to different tilting gates simply by setting the positions of the end stops in the rail in a suitable manner. This adjustment can be made either during installation of the device on site or at the factory. Particularly advantageously, the door leaf and the rail with suitably adapted to the door leaf end stops form a prefabricated unit.

A significant advantage of the device according to the invention consists in the specific design of the actuating rod with a segment of this actuating rod such that it is guided on approach of the drive unit from an open position of the door leaf against a stop on the door leaf, whereby the upper end of the door leaf is raised. As a result, a tilting movement of the door is initiated in a structurally simple manner already at the approach of the drive unit, so that thereafter the door leaf can easily be moved along its desired path.

In this case, the stop is particularly advantageously formed by a roller mounted on the upper edge of the door leaf.

This ensures that the contact between the actuating rod and stop can be done without wear.

Another significant advantage of the device according to the invention is that it does not limit the passage height given by the height of the door opening. This advantage is particularly important if the tilt gate is used to close a garage. When the tilt gate is open, the door leaf lies in the area of the garage ceiling. In this position, constructions protruding from the inside of the door leaf would undesirably reduce the headroom. The integration of the insert with the end stops in the rail a unit with very low height is obtained, so that this unit can be mounted on the inside of the door leaf without reducing the headroom. In addition, the actuating rod is formed by their specific shape so that it does not lead to a reduction in the passage height.

Due to the fact that only one integrally formed actuating rod is required for coupling the drive unit to the door leaf, and the motion compensation of the door leaf and actuating rod required for carrying out the tilting movement of the door leaf is ensured by the guidance of the actuating rod in the rail Drive rail can be kept small, that is, the drive rail can be sized accordingly short. The rail on the door leaf to guide the insert can be kept low. This also allows easy installation of the device according to the invention in confined spaces.

In this case, it is particularly advantageous if the insert has a hinge connection located inside the rail for coupling the actuating rod.

In the open position of the door leaf, its guide rollers guided in the guide rails are higher than the articulated connection of the insert.

Due to the arrangement of the articulated connection in the insert itself, an extremely small projection of the actuating rod is achieved via the rail, so that no reduction of the passage height is obtained with the actuating rod. Due to the position of the articulated connection in use above the rollers in the open position of the door leaf, it is achieved that the tilting movement of the door leaf can be initiated without great expenditure of force when receiving the drive unit from the open position.

A further significant advantage of the device according to the invention is that with the rail receiving the insert an additional stabilization of the tilting gate during the closing and opening movement of the door leaf is obtained. Namely, the rail extending in the direction of the drive rail represents a stable guide means which stabilizes the door leaf in the course of tilting movements. In this case, the rail is particularly advantageously designed as a C-profile rail, which has a structurally simple structure and is also inexpensive to produce.

According to the invention, the insert on pressure elements, by means of which the insert is pressed with a contact pressure against the rail.

The pressure elements are formed by spring elements which are provided on the lateral edges of the insert and which press against side walls of the rail.

By these pressure elements, the necessary displaceability of the insert is retained, but it is ensured by this that when performing tilting movements of the door leaf, the guided against one of the end stops insert remains in this desired position, whereby a continuous guidance of the door leaf is guaranteed.

FIG. 1 schematically shows the structure of a tilting gate 1, which serves in particular for closing a door opening of a garage. The tilt gate 1 comprises a door leaf 2, which is guided with guide rollers 3 mounted laterally in vertically extending guide rails 4. FIG. 1 shows the door leaf 2 in its closed position, in which the door leaf 2 mounted in a vertical plane closes the door opening. From this closed position, the door leaf 2 can be moved under execution of a tilting movement in an open position. In the open position, the door leaf 2 lies substantially in a horizontal plane above the door opening.

The guide rails 4 are each arranged in housings 5 which adjoin the lateral edges of the door leaf 2. In the cases 5, a weight compensation device is integrated in each case. This consists in each case of a balance weight 6, which is coupled via a cable, which is guided via a deflection roller 7, to the respective guide roller 3 of the door leaf 2. With the weight compensation devices is achieved that the door leaf 2 is held stable in each tilting position by itself.

The Figures 2 and 3 show the components of a device for actuating, that is, opening or closing the tilting gate 1. It shows FIG. 2 the device with open tilt gate 1, that is with the door leaf 2 in his Open position. FIG. 3 shows the device with the tilt door 1 closed, that is, with the door leaf 2 in its closed position.

The device comprises a drive unit 8 which can be moved on a drive rail 9. The drive rail 9 extends in the horizontal direction in the direction of movement of the tilting gate 1. The drive rail 9 is arranged above the door opening. The drive unit 8 consists essentially of a carriage, in which a not shown separately electric drive is integrated. The electric drive is via a gear or the like in engagement with a running in the drive rail 9 traction means such as a chain, a toothed belt or the like, so that by means of the drive of the carriage along the drive rail 9 can be moved.

For coupling the drive unit 8 to the door leaf 2 is a single, integrally formed actuating rod 10 is provided as a linkage. One end of the actuating rod 10 is coupled by means of a first articulated connection in the form of a roller bearing 11 articulated to the drive unit 8. The articulation is located in a projection 12 at the front, the door leaf 2 facing the end of the drive unit. 8

The second end of the actuating rod 10 is coupled via a second hinge connection in the form of a rotatably mounted roller 13 to an insert 14 which is slidably mounted in a rail 15 which is fixed to the inside of the door leaf 2. The roller 13 has in the present case in the form of an elongated bolt with a circular cross-section. The rail 15 is formed as a C-profile rail, which is arranged in alignment with the drive rail 9, that is, the longitudinal axis of the rail 15 coincides with that of the drive rail 9 together.

The rail 15, the in FIG. 4 is shown separately in a longitudinal section and which in FIG. 5 is shown in a cross-sectional view, has a constant over its entire length width. On the side walls 15a projecting from the bottom 15b of the rail 15, inwardly projecting protrusions 15c are provided so that the insert 14 can not come out of the rail 15 and yet the top thereof is largely exposed (FIG. FIG. 5 ).

In the rail 15, two end stops 16a, 16b are also fixedly mounted. The positions of the end stops 16a, 16b are determined application-specific for the respective tilt gate 1. The determination is made either factory by the gate manufacturer or during assembly of the tilt gate 1. In particular, the end stops 16a, 16b are formed by cuboidal bodies, be screwed into the rail 15. The widths of the end stops 16 a, 16 b are adapted to the width of the rail 15.

The insert 14 is slidably disposed in the rail 15 and can be moved between the end stops 16a, 16b. If the door leaf 2 from its open position ( FIG. 2 Moves out through the drive unit 8 and the actuating rod 10, the insert 14 initially moves against the end stop 16a and then remains at this during the entire tilting movement until the door leaf 2 moves into the closed position. If, however, the door leaf 2 from its closed position ( FIG. 3 Moves out through the drive unit 8 and the actuating rod 10, the insert 14 initially moves against the end stop 16b and then remains at this during the entire tilting movement until the door leaf 2 moves into the open position.

In order to hold the insert 14 during the travel movements of the door leaf 2 at the respective end stop 16a, 16b, pressure elements are provided laterally on the insert 14, which exert a certain contact pressure on the side walls 15a and thus ensure that the end stops 16a, 16b only are overcome by overcoming a certain force in the rail 15. In the present case, the pressure elements are formed by laterally opening on the insert 15 spring elements 17 which press directly or through a cover of the insert 14 against the rail 15 ( FIGS. 4 and 5 ). By thus obtained constant contact of the insert 14 on the end stops 16a, 16b abrupt movement deflections are avoided in the tilting movement of the door leaf 2 in a simple manner.

By the rail 15 for guiding the actuating rod 10 receiving insert 14, the stability of the tilt gate 1 is increased. A further increase in stability is obtained by the fact that the roller 13 is increased for receiving the end of the actuating rod 10 at its longitudinal ends, thus providing a forced guidance for the actuating rod 10 ( FIG. 4 ).

The device of Figures 2 and 3 can be used for different tilt gates 1. In an application-specific adaptation of the device to a tilting gate 1, only the position of the end stops 16a, 16b in the rail 15 has to be specified individually.

Thus, the components of the device for actuating tilting gates 1 of different types can be used. This is especially true for the actuating rod 10, which, as from the Figures 2 and 3 can be seen, consists of different rectilinear sections.

One of the sections forms a segment 10a running along a straight line, which connects to the end of the actuating rod 10, which is coupled to the articulated connection of the drive unit. This segment 10a is designed to be in the (in FIG. 2 shown) opening position of the door leaf 2 extends at an inclination angle to the horizontal and lies below a stop at the upper edge of the door leaf 2. This stop is formed in the present case by a rotatable roller 2 on the door leaf 18.

In the opening position of the door leaf 2 ( FIG. 2 ) If the drive unit 8 now moves on, the segment 10a of the actuating rod 10 is lifted from below against the stop formed by the roller 18. As a result, the tilting movement of the door leaf 2 is initiated in a simple manner. It is advantageous if in the open position of the door leaf 2 whose guide rollers 3 are lower than the hinge connection for coupling the actuating rod 10 to the drive unit 8, since otherwise the initiation of the tilting movement would be possible only with increased effort.

There, how out FIG. 2 can be seen, both the rail 15 on the door leaf 2 and the actuating rod 10 in the open position of the door leaf 2 do not protrude far down, these elements do not protrude into the door opening and thus not limit the passage height of the tilt gate. 1
