Description

The Innovation relates to a drive unit or an actuator for doors according to the generic term Protection claim 1.

power units or actuators for doors, in particular even those with a motor, such as electric motor drive for motor opening of the respective door leaf and with a work or accumulator that charges when opened and through Unloading a moving the door leaf in the closed position causes are basically known. As a base or support element on which the functional elements the actuator are provided and with the actuator above a door opening at one there attachment surface is mountable, is used in known actuators massive Plate made of a metallic material, for example aluminum. This support plate is then mounted to a mounting plate by screwing, in turn, above the door opening a mounting surface, for example on a wall surface or area surrounding a door opening Stockframe is attached.

There Both the support plate, and the mounting plate are flat, is for both Plates require a significant material thickness to provide adequate Bending stiffness for the relatively heavy drive structure or the relatively heavy functional elements and especially for the ones to be transferred driving forces and achieve moments. For Cable glands from the building wall or door to the actuator are holes necessary in the plates. These are usually fixed, which a precise routing of the outer connecting cables or - cable and their release from the mounting surface required. If in the support plate and in the mounting plate the actuator provided holes do not fit or can not be used, need more holes in the plates are drilled during assembly.

Consists the support plate are made of aluminum or an aluminum alloy so for the Attachment of the functional elements on this plate basically threaded screws with Nuts required. The use of thread cutting screws is then not possible as these are usually not sufficient anchoring in aluminum to ensure.

The open side of the hat rail or hat profile-like cross section forms the underside of the mounting rail, with the mounting device mounted adjacent the respective mounting plane. The special profile allows the functional elements according to their specific training to fix in an optimal way. For example, at the Top of the hat-shaped Contour or hat-shaped cross-section both electrical and mechanical components are screwed. Boards or other components that are oriented perpendicular to the mounting surface are, can at the perpendicular to this mounting surface oriented legs the mounting rail also secured by simply screwing become. As screws are then for example thread cutting Screws.

Farther can in the clear cross section of the mounting rail cables and cables are performed, and while protected across from movable or driven elements, which are then above the top Support rail are arranged.

In detail, the operating lever 6 starting from the shaft 7 a first section 6.1 on, in which this lever is curved convexly on its leading edge in the closing movement (arrow A) and has a relatively short length. In the section 6.1 The slot also extends 8th with a short part length 8.1 , which is also the curvature of the operating lever 6 is convexly curved according to the leading in the closing movement A side.

To the section 6.1 the section closes 6.2 on, on which the actuating lever is concavely curved at its in the closing movement (arrow A) leading side and in which also the slot 8th with the longer section 8.2 extends, the shape of the operating lever 6 following with a curvature such that in the direction of the closing movement (arrow A) leading side of the section 8.2 is concavely curved. The curvature in the section 8.2 is designed so that the radius of curvature with increasing distance from the axis of the shaft 7 decreases or vice versa with increasing distance from the free, the shaft 7 remote end of the operating lever 6 increases. The curvature is chosen so that in each open position of the door leaf 3 about that of the spring device 16 generated moment on the door 3 a possible optimal and a certain threshold not undershot closing moment is exercised. This is the course of the long hole 8th especially chosen so that by the moment of the spring device 16 on the role 9 applied force K as perpendicular as possible to the respective connecting line 52 between the axis of the roll 9 and that through the bands 4 defined pivot axis of the door leaf 3 is oriented. Furthermore, the shape of the operating lever 6 also chosen so that an open position of the door leaf 3 greater than 90 ° is possible, for example, an open position of 100 ° -110 °, without parts of the operating lever 6 excessively wide, ie much further than the roller bearing 10 or the elbow 49 over the door 3 protrude, so the actuator 5 can also be used on such doors where the open door leaf 3 a wall is immediately adjacent.

In the same way is by the described course of the elongated hole 8th or the control cam formed by this slot also achieved that when pivoting the door leaf 3 in the opening direction between the operating lever 6 and the role 9 acting force also as perpendicular to the connecting line 52 is oriented.
