Description

The invention relates to an overhead door closer with a actuated by a spring arrangement in the closing direction Closer shaft.

An overhead door closer is known from DE-OS 33 45 004 become, in which a closing force and Opening force characteristics like with a door closer with Scissor rods can be achieved. The damping of the Door leaf regardless of that in the same rotation angle range Chen the closing force accruing closing forces been done. Due to the different design of the Curve tracks become the spring support member and also the damper depending on the door opening angle or angle of rotation certain, depending on the opening and closing characteristics assigned strokes allocated. Through this inventive spirit The closing force curve on the door leaf is such an idea lized that in its closed position a relatively high Closing moment for pressing the door leaf against the door seal is present. At the same time when opening angle of the door leaf of about 2 ° is a steep drop Opening moment achieved that over the further door opening away until the door opening angle remains almost constant and even optionally falling further or back on again can increase. That kind of door closers read are particularly useful on fire doors.

DE-OS 18 07 399 discloses an automatic door closer, which with a symmetrical hub curve is equipped. This door closer is about is a floor closer, where the closer shaft only protrudes from the housing on one side.

The object of the invention is a cost-effective to develop sliding rail door closers for all types of installation must be used, d. H. Right- / Left stop on the hinge side or opposite hinge side both in normal assembly on the door leaf and in overhead days on the door frame. Without additional assembly work the closer must be the same in both directions Closing damping and the same torque curve bring.

The object of the invention is achieved by a Upper door closer with the features of claim 1 solved. Thereby, that the cam disc has been constructed symmetrically, the door closer can be the same in both directions Engage the curve shape. Due to the symmetrical The cam disc is the same in both directions Cher torque curve and also a same closing damping achieved. The NO shaft end is also only at one end from the door closer housing been carried out. The advantage is that only one Axle sealing in the area of the closer shaft required becomes. Located at the end of the emerging closer shaft an entourage, e.g. B. a square on which the actuating arm is raised is set, which in turn in the guide rail on the other hand finds its hold. To the necessary pressure To reach a door, the square is in the actuation arm lever offset by at least 3 °. This ensures that the door closes safely in any case. Due to the geometric design of the actuating arm can this Lever in two directions of the respective assembly situation tion for right and left hinging of the door accordingly be used.

Are on its housing three attachment points that are designed so that z. B. are located on the top of the housing and on the opposite underside of the housing exactly in the Middle of the third attachment point is present. Here is achieved by that in connection with an assembly plate of this overhead door closer can be used universally can.

The invention is shown on a schematically Embodiment, which Darge in the drawings has been explained below. It demonstrate:

Fig. 1 the upper section of a door in perspective view, a top door closer is mounted at the door leaf, which engages with the free end of the actuating arm in a door frame arranged on the guide rail,

Fig. 2 overhead door closer in a vertical section,

Fig. 3 Overhead door closer in a horizontal section,

Fig. 4 operating arm in the side view,

Fig. 5 operating arm in plan view,

Fig. 6 housing in section;

Fig. 7 mounting plate in side view,

Fig. 8 mounting plate seen from above.

The overhead door closer ( 12 ) is attached to a door leaf ( 10 ) at its upper edge. The door leaf ( 10 ) is attached to a frame ( 11 ). The actuating arm ( 14 ) is held on the one hand on the closer shaft ( 13 ) and on the other hand in the guide rail ( 15 ).

In particular in Fig. 2 it can be seen that the closer shaft ( 23 ) is only made on one side out of the housing ( 16 ). The within the housing ( 16 ) Liche normally open shaft end ( 45 ) is in a La ger ( 18 ). As a result, the closer shaft ( 23 ) is supported with respect to the housing ( 16 ). At the free emerging end of the closer shaft, the axle exit ( 41 ), there is a driver shaft ( 17 ). However, this closer shaft end is also stored in a bearing ( 20 ) within the housing. A sealing ring ( 21 ) seals the closer shaft ( 23 ). By this inventive measure, only one shaft end of the closer shaft ( 23 ) is performed, and thus only one seal must be made. The bearing ( 20 ) with the sealing ring ( 21 ) is located in a bearing ring ( 19 ) which holds the closure the closer shaft ( 23 ). Within the housing (16) is located on the closer shaft (23) has a symmetrical executed cam disc (22). This cam disc ( 22 ) is in direct contact with the force transmission roller ( 26 ) and the roller ( 35 ), which are arranged axially to the housing axis and the closer shaft ( 23 ). These rollers have in turn been rotatably supported by the axle bolts ( 27 ) and ( 36 ). The cam disc ( 22 ) is permanently mounted on the closer shaft ( 23 ). The closer shaft ( 23 ) is however rotatably supported in the La like ( 18 ) and ( 20 ).

As can be seen from Fig. 3, the lift cam disc ( 22 ) with its curved tracks ( 24 ) and ( 25 ) symmetrical to the center axis of the overhead door closer.

These curved tracks ( 24 ) and ( 25 ) together form an approximately heart-shaped circumferential contour. Thanks to this symmetrical structure, the same torque curve is achieved with the same closing damping for every type of installation. The position of the cam disc ( 22 ) shown in Fig. 3 corresponds to the closed position of the overhead door closer. The power transmission roller ( 26 ) is located on the axle bolt ( 27 ) within the spring support member ( 28 ). The compression spring ( 29 ), which rests with its other end against an abutment ( 31 ), presses against the spring support member. The abutment ( 31 ) is disc-shaped and has a threaded bore in its center into which the threaded shaft ( 33 ) of an adjusting pin ( 32 ) engages. The adjusting pin ( 32 ) in turn engages in the screw-in sealing plug ( 34 ) which is located on one end of the housing ( 16 ). The roller ( 35 ), which also presses against the cam disc ( 22 ), is located in the damping piston ( 37 ). Presses against the damping piston ( 37 ), the compression spring ( 46 ), which is supported against the plug ( 30 ), which is located within the second end face of the housing ( 16 ).

When the door leaf ( 10 ) is actuated, the closer shaft ( 23 ) is rotated, which means that the cam disc ( 22 ) rotates.

On the driver shaft ( 17 ) of the closer shaft ( 23 ), the actuating arm ( 14 ) is positively and non-positively introduced. This can e.g. B. happen that there is a square, hexagon or polygon or a serration on the driver pin, which / must accordingly be in the actuating arm ( 14 ). In the embodiment of FIG. 5 has a recess (42) has been executed as a square. In this game Ausführungsbei should be shown that the square is not in alignment with the central axis of the actuating arm. This recess ( 42 ) has been made through an angular offset ( 44 ) of at least 3 ° with respect to the central axis ( 43 ). Furthermore, in an embodiment of the invention, the actuation arm has been created as a flat arm without any offset. Due to these two decisive features, flat straight design and offset ( 44 ) of the recess ( 42 ), the actuating arm ( 14 ) can be used universally. This has the result that the same actuating arm can be used in the assembly of the door closer on the hinge side or the counter hinge side, both in normal assembly on the door leaf and in Kopfmon days on the door frame with a right or left stop.

The entire overhead door closer is mounted on a mounting plate ( 48 ) shown in FIGS . 7 and 8. The actual fastening of the overhead door closer is connected to the mounting plate ( 48 ) via three fastening points ( 38 ), ( 39 ) and ( 40 ) located on the housing. Two attachment points ( 38 ) and ( 39 ) are located e.g. B. on the top of the housing ( 16 ) at the closer shaft outlet ( 41 ). The third attachment point is on the opposite lower side of the housing. However, so that the housing can be turned over on the envelope, the opposite attachment point ( 40 ) must be exactly in the middle of the axis between the two attachment points ( 38 ) and ( 39 ). This is the only way to ensure that the same mounting plate ( 48 ) can be used when the entire housing is rotated. The mounting plate ( 48 ) is equipped with corresponding mounting bolts ( 49 ), ( 50 ) and ( 51 ). These mounting bolts rise on the plate and are arranged so that the Ge housing with the three attachment points ( 38 ), ( 39 ) and ( 40 ) is congruent with the bolts ( 49 ), ( 50 ) and ( 51 ). As can be seen from FIG. 6, which shows a section through the housing, there is a recess ( 52 ) in the housing into which the mounting bolts ( 49 ), ( 50 ) and ( 51 ) fit. This means that the position of the overhead door closer is precisely fixed on the mounting plate. There is an internal thread inside the mounting bolts ( 49 ), ( 50 ) and ( 51 ) so that the housing ( 16 ) can be connected to the mounting plate ( 48 ) by means of screws. The mounting plate ( 48 ) as such can then be attached to the door leaf or to the door frame via the mounting holes ( 53 ). This universal type of installation makes it possible to create a universal overhead door closer with a slide rail linkage in conjunction with the symmetrical cam disc ( 22 ). This possible solution allows all types of installation to be carried out with just one overhead door closer.
