EP0573784B1 - Linkage for actuating swinging wings, particularly doors and the same - Google Patents

Abstract

A linkage for actuating swinging wings, such as doors (5) and the like, consists, as a rule, of a toggle-lever linkage (11). In order to avoid the risk of a possible shearing and pinching effect between the two levers (11a, b), particularly in their initial or closing position, provision is made for at least one of the two levers (11a, 11b) to be provided with an angular extension (23) projecting transversely away from the lever. This angular extension (23) can be dimensioned in such a way that, where a sliding linkage is concerned, whilst any pinching effect between the first and second lever (11a, 11b) or a rail (11c) is avoided, the spacing over the entire length of the levers or the rail is sufficiently large. <IMAGE>

Description

The invention relates to a linkage for driving rotary blades like doors and the like according to the generic term of Claim 1.

A swing door operator is for example from the brochure "Record-automatic swing door operator DFA 125" from AG has become known for door automation. Between the actual drive unit housed in a housing and for example the upper door frame becomes conventional a V-shaped linkage, d. H. a toggle related. By turning the output shaft of the drive unit one of the two levers of the The toggle lever is set in rotation via the articulated connection the second lever of the knee lever and thus ultimately the door to be operated swings open and closed.

It is a so-called standard linkage, which in its rest position is usually in the manner of a almost closed V's above the door to be moved more or less protrudes vertically from the door plane.

However, so-called parallel linkages are also known become, in which the two to the knee joint drive belonging lever rather in parallel position to the door level are aligned. The drive and the function correspond but otherwise the standard linkage.

In the above Leaflet is also a so-called sliding linkage shown. Here is one at the Door self-attached slide rail related, in which the one connected to the output shaft of the drive unit Lever engages. The slide rail attached to the door serves as a second lever, the free end of the Rotatable lever can be moved along the rail is, so in the manner of one during the opening and The closing process of the door is not fixed but relative locomotive articulation.

The rods that became known in this context have been quite successful for years and decades related and used. However, these rods contain also certain disadvantages and dangers.

Generic drive linkages for rotary blades are for example from FR-A-2,359,447, US-A-2,053,172, US-A-3,510,984, FR-A-1,008,504 and US-A-3,135,845 known.

It is therefore an object of the present invention Linkage for driving swing leaves such as doors and the like to create, which compared to the state of the Technology with an overall still simple structure increased security against crushing or shearing off especially with an intervention perpendicular to the planes of movement the lever has.

The task is according to the invention in accordance with the claim 1 specified features solved. Advantageous configurations of the invention are in the subclaims specified.

The present invention creates and amazingly Way a significant improvement in security standards such linkage. Because after the Rods that have become known in the prior art show especially when pivoting in the locked position. Because in the closed position they are over the two over one Articulated lever in a V position brought, at which the maximum distance between the Lever is often less than 2 or 3 cm. In the direction the distance between the joint itself is scissor-like from, so that in the worst case when closing a hand inserted between the two levers or a Fingers could be crushed and sheared off.

This problem basically applies to all of the above called pivoting mechanisms known from the prior art. So much for the state of the art one of the pivoting levers in the area of the articulated connection slight offset to the second lever arm (offset) has this technical training basically a different function. Because such low cranking is necessary to two levers in one Plane transverse to the joint axis at least almost in parallel to be able to pivot towards each other. Otherwise it would namely the two lever arms when swiveling towards each other collide with each other, so that a parallel course of the two swivel arms or one that only differs slightly Alignment of the pivot lever in an operating position would not be possible.

In contrast, the present invention proposes that the provided at least on one of the levers and in the transverse direction protruding additional lever approach so formed is, i.e. its length and orientation so dimensioned is that in the locked position the two levers e.g. a Assume parallel position to each other, their distance from each other is more than 40 mm and thus sufficiently large is dimensioned that a pinch of fingers or the entire hand is safely avoidable.

A generic linkage for driving rotary sashes is basically also from DE-Z "BKS GmbH: The attack. In: Baubeschlag Magazin, 1957, Issue 3, pages 37 and 38 ". According to Figure 108 of this document it is shown that at least one of the two levers provided with an angular extension projecting transversely from the lever is so that between the first lever and the second Lever a distance along their entire length is available. By creating a height difference between the fastening points of the closer and the Fork arms like some security improvement achieved compared to other conventional solutions become. Always sufficient security for everyone conceivable cases can be with such Do not implement the solution.

In a particularly preferred embodiment of the invention one end of the lever is fork-shaped and picks up the other end of the second lever. As a result, both levers can be arranged lying in one plane will. Unwanted additional tilting moments at the Power transmission is avoided.

In Figure 1 is a partial schematic representation a door frame 1 with a pivot axis pivotable swing door 5 shown. In the embodiment is on the upper horizontal cross member of the door frame 1 mounted the housing 7 of a rotary leaf drive 9. Via a drive shaft emerging at the bottom of the rotary leaf drive 9 is formed in the form of a toggle Linkage 11 driven to turn the swing door 5 to open and close.

The exact structure and how it works is as follows explained with reference to Figures 2 and 3.

In Figures 2 and 3 is a vertically extending drive shaft 13 (drive axle) shown, which at the same time the Output shaft of the rotary leaf drive 9 represents and at corresponding, as a rule, electric drive in Figure 2 shown in its starting and closed positions Swivel the first lever 11a along the circular path 17 can.

The second lever 11b of the linkage 11 is on the swing door 5 articulated via a joint 19.

Both levers 11a and 11b are connected via an articulation 21 connected.

The illustration also shows that the shown Embodiment of the first lever 11a adjacent to the Articulated connection 21 with a lever or angled shoulder 23 is provided. This results in an L-shape, hereinafter also called golf club form for short.

The length of the lever angle projection 23 is preferably so chosen that it is usually more than 4 cm, preferably more than 4.5 cm, 5 cm etc. until, for example, if necessary can also be 10 cm and even more, depending on the circumstances and requirements. Usually the length chosen so that the rear distance between the Drive shaft 13 and the joint 19, that is between the two articulation points of the two levers 11a, 11b on the rotary leaf drive 9 or the swing door 5 at least in corresponds approximately to the length of the angle projection 23, so that the two levers lla or 11b with the appropriate distance are aligned substantially parallel to each other and usually at an angle of around 90 ° from the door level protrude.

Partially reproduced in section from the one shown in FIG Illustration shows that the one with the Angle projection 23 provided lever 11a in a fork-shaped End 27 runs out, in which the hinge axis 21 'held on which one with one of the hinge axis 21 ' penetrated cross hole and to lever 11b belonging pin 12 is pivotally anchored. By this arrangement makes it possible to ensure that the Linkage 11 and thus both levers 11a and 11b in one common plane perpendicular to axes 13, 19 and 21 ' lie. This allows undesirable when swiveling Avoid tipping moments.

To open the swing door 5 is not shown in Way of the rotary leaf drive 9 operated, so that the first lever 11a from that in FIG. 2 to that in FIG 3 shown position is pivoted, what under appropriate Swiveling the second lever 11b the door is brought into the open position shown in Figure 3. The closing process is reversed, with the specific design of the rod 11 itself when inserting fingers or hand into the space between the two levers 11a and 11b the fingers and the Hand cannot be squeezed because of the distance is sufficiently large.

Deviating from the embodiment shown could of course also the other lever 11b with the angle shoulder 23 or both levers with an appropriate angle approach be provided. The cable end 27 could be different from the embodiment shown on the other lever be provided.

Basically, it is also possible to use both levers around the Thickness of the respective lever in the joint axis direction 21 ' staggered to link to each other, at least then low tilting moments can occur.

Figures 5 and 6 show an example in which the linkage 11 shown in the manner of a parallel linkage is.

The term "parallel linkage" is used when one Lever 11a roughly parallel to the level of the swing door 5 is aligned. The second with the first over the link 21 connected lever 11b then engages on a rotary wing approach 5 ', which is a fixed short column z. B. approximately at right angles from the plane of the Swing door 5 extends away.

When using the invention are also in the closed position the two levers 11a and 11b in one are sufficient large distance to each other aligned so that no bruises can occur here either. The distance can optionally be chosen so that in Closed position the distance between the over the housing 7 approximately in the parallel position projecting forward Lever 11b at a sufficient distance from the actual one Housing 7 comes to rest, so that in this embodiment also no bruise between this second Lever 11b and the corresponding housing wall of the housing 7 can arise.

The same applies in principle to that in the figures 7 and 8 illustrated example using a so-called Sliding linkage. Here takes effect at the point where in the other exemplary embodiments the hinge axis 21 ' is provided, a corresponding hinge pin 21 "in a rail 11c attached to the rotary wing 5. At the This hinge pin 21 "will open and close in the Rail 11c shifted. This hinge pin 21 "can so far also as when opening and closing along the swing door 5 movable articulation between the first lever 11a and that in the sense of a second lever 11b acting rail 11c can be understood. This one too Embodiment, the lever 11a next to its an angular approach 23 yet another in the area of the drive shaft 13 of the rotary vane drive 6 further, in the same Provide lateral direction extending angle approach be so that there is also no crushing between the Lever 11a and the rail 11c or the housing 7 of the rotary leaf drive 9 can occur. In this case the angle should be shaped the same, so that the section of the For example, lever lla parallel to one between its two opposite articulation points Is aligned.
