The lever swivels on a second pivot axle at a distance from, and especially below, the fixed first rotary axle of the flap. A first end of an extra reversing lever (9) swivels on a third pivot axle on the drive element. A second end of the reversing lever is mounted on a fixed pivot point (P2). The first swivel axle (P5) of the linear drive element on the support lever, and the third swivel axis (P4) on which the reversing lever on the linear drive element swivels describe circular paths when the linear drive element is operated. The circular paths intersect so as to turn the linear drive element.

Description

The invention relates to a hinge assembly for actuation a flap or the like according to the preamble of the claim 1.

The joint arrangement can in light domes with a curb be used in which a fixed console is mounted. On the curb a fan frame is movable attached with hinges. In one embodiment the dome lights rest on the fan frame; in another Embodiment is the fan frame as a border frame for formed the dome light. Furthermore, the invention for Lichtbänder, so-called light streets are used, the have a frame instead of a curb. With the Joint arrangement can be single or double flaps made of sheet metal be actuated or slats of a lamellar fan. Generally, with the hinge assembly a rotatable or tiltable Element, such as B. actuates a flap or a blade.

The hinge assembly is intended to meet the requirement for SHE system, i. Smoke and heat exhaust systems meet, where a smoke vent in alarm position a large opening angle of should reach about 165 °.

A known joint arrangement of the type mentioned is completely independent in and out of such an alert operable, with the opening and closing of a Flap over a whole large swivel range to about 165 ° may be, for which only a drive element is needed.

In such a known hinge assembly is an end of a linear drive element at one of a stationary first Rotary axis of a flap or dome remote location of the flap pivotally mounted on a truss part of the flap. On the other hand, the linear drive element is a first Swivel axis pivotally mounted on a support lever, the in turn around a fixed second pivot axis nearby the axis of rotation of the flap is pivotable. This is the first Swivel axis approximately in the middle of the longitudinal extent of the support lever. An additional bellcrank is with a first end at an end remote from the second pivot axis of the Support lever arranged pivotally. A second end of the reversing lever engages pivotally on the truss part of the flap at a distance to its axis of rotation and to the mounting location of the first end of the drive element (EP 0 443 050 B1). These Joint arrangement is distinguished from other joint arrangements by a relatively space-saving position of the linear Drive elements, in particular a lifting cylinder, off. In a less space-saving variant of the joint arrangement with only one linear drive element is at the first Pivot axis of the additional lever with a first end pivotally arranged, the second end of the truss part the flap at a distance to its axis of rotation and to the mounting location the first end of the drive element attacks. - In a further variant of the joint arrangement with only a single linear drive element is this with its second end about a fixed third pivot axis swiveling, with a fixed second truss part or truss bottom in solid connection standing deeper as well as from the first axis of rotation about which the flap pivots is located more distant than the second pivot axis is about which the support lever is pivotable. The order is designed such that the distance of the third pivot axis is dimensioned larger than the first pivot axis Removal of the pivot point of the reversing lever on the truss part from the first axis of rotation and is greater than the distance of the second pivot axis of the first axis of rotation. - All these Known joint arrangements have in common that by the linear Drive element on the truss part additional lateral forces be initiated, which is a correspondingly fixed Traverse require.

The invention is therefore based on the object, a joint assembly of the type mentioned above in such a way that this on the flap, lamella or the like, at the linear drive element attacks, no additional lateral forces initiates, so that the traverse or a truss bottom is not required. This should also be a light, material-saving Construction of the linear drive device and hinge assembly actuated element.

This object is achieved by the training of Joint arrangement with the features specified in claim 1 solved.

The hinge assembly with these features can be designed be that they are also used to operate smoke flaps in SHE systems have a large opening angle with completely independent Opening and closing allows, without being on the smoke damper flap to apply additional lateral forces, the otherwise intercept by a truss part. It will only Forces in the flap or the actuatable element the axis of rotation or hinge as well as on the swivel executed Location of the linear drive element on the Flap, the latter location substantially parallel to the axis of rotation is opposite, initiated. Reaction forces of the linear Drive elements are via the lever and the support lever only in a fixed pivot point of the reversing lever or a stationary second pivot axis of the support lever initiated. The hinge assembly according to the invention may be in their dimensions adapted flexibly to given operational requirements as long as the characteristics of the characterizing part of the Claim 1 are satisfied. To the design of the depository the second end of the reversing lever at a fixed pivot point and the third pivot axis about which the bellcrank the linear drive element is pivotable must be observed be that the first pivot axis of the linear drive element on the support lever and the third pivot axis to which of the lever on the linear drive element is pivotable when operating the linear drive element describe circular trajectories that intersect and cause a resultant rotation of the linear drive element. In addition, the drive element can be linear move, in the case of a flap, to which the linear drive element, in particular a piston rod a compressed air cylinder in the closed state from below engages, during the rotation of the linear drive element this simultaneously moved up. The despite this kinematics uncomplicated realizable joint arrangement has the other Advantage of a very flat design, so that the hinge assembly with linear drive element not or only very little from a normal top frame or curb on which a flap is articulated, protruding downwards. Depending on Space or strength of the top frame or Frames in which the hinge assembly with the drive element can be used, an optimal design can be achieved become.

The required, above-described kinematics of the joint arrangement is achieved according to claim 2 in particular by that the third pivot axis about which the linear drive element is pivotable on the bell crank, closer to the end the linear drive element which faces away from the flap is arranged as the first pivot axis to which of the Support lever is pivotable on the linear drive element. It also follows that the lever over a larger Length is rotatably mounted on the linear drive element as the support lever. It should be noted at this point that the lever and the support lever as the first rocker arm and second rocker arm can be called.

A simple basic form of the joint arrangement is apparent according to claim 3, characterized in that the second end of the reversing lever at the fixed pivot closer to the stationary first axis of rotation of the flap as the stationary second pivot axis the support lever and preferably under the fixed second pivot axis of the support lever is mounted.

This embodiment is especially recommended for a fixed Console in a curb.

Using this console is fixed according to claim 4 Fulcrum of the second end of the bell crank on the fixed console, which is near the axis of rotation of the flap from this in its closed position preferably in Substantially perpendicular to this protrudes, in essence arranged below the axis of rotation of the flap. The stationary second pivot axis of the support lever on the console is in substantially below the fixed pivot point of the second End of the reversing lever attached to the console.

In a particularly advantageous manner, no guidance is parallel to the linear drive element required if according to claim 5, the third pivot axis at the first end of the reversing lever and the first pivot axis of the linear drive element the support lever in the central axis of the linear drive element lie.

According to claim 6, the use of a linear is recommended Driving element, which is suitable, by the hinge assembly to absorb generated side forces or bending forces.

As on the actuatable element, at which one end of the linear Drive element attacks, however, no additional lateral forces can be introduced through the hinge assembly, according to Claim 7 of this actuatable element or the flap constructive easy and low-mass on her to the fixed pivot point remote end immediately, i. without insertion of one Truss part with the linear drive element in swivel Be associated.

In a particularly space-saving hinge assembly is located the third pivot axis about which the linear drive element is pivotable, at one end of the support lever. In the Case in which a Doppelhubzylinder as a linear drive element can be used over the third pivot axis Compressed air are supplied, as well as the first Pivot axis of the linear drive element on the support lever.

In Fig. 1, 1 denotes a curb, on which a flap by means of a hinge about a stationary first axis of rotation P _{0 is} pivotable. At the opposite end to the first axis of rotation P ₀ engages the flap 2 via a locking element 3, a piston rod 4 of a Doppelhubzylinders 5 as a linear drive element. The pivotable connection of the piston rod to the locking element 3 and the flap 2 is designated P ₁ . The locking element cooperates with a locking bracket 6 which is fixedly mounted inside the curb, such that upon actuation of the piston rod 4, see Fig. 2, an unlocking takes place.

At the opposite side to the pivotable connection point P ₁ , namely in the vicinity of the first axis of rotation P ₀ , a bracket 7 is fixed to the inside of the curb, which protrudes approximately at right angles and perpendicularly downward with respect to the closed flap 2. The bracket 7 serves to support a support lever 8 and a reversing lever 9, whose one end with a fixed pivot point P ₂ closer to the stationary first axis of rotation of the flap is arranged as a fixed pivot axis P _{3 of} the support lever 8, wherein the fixed pivot point P ₂ and the fixed pivot axis P ₃ are arranged here along a vertical line. The support lever 8 is arranged with an opposite to the stationary pivot axis P ₃ end to the Doppelhubzylinder 5 and that in the central axis 5a of this Doppelhubzylinders 5. P ₅ forms the first pivot axis of the Doppelhubzylinders 5 on the support lever 8, in the region of one end the double-stroke cylinder is arranged opposite to the pivotable connection point P ₁ on the locking element 3 or the flap 2. Still closer to the end of Doppelhubzylinders 5 than the first pivot axis P ₅ , the pivot axis P _{4 of} the reversing lever 9 is arranged. The pivot axis P ₄ is referred to as the third pivot axis, because at least one second pivot axis is present at the pivotable connection point P ₁ .

Upon actuation of the Doppelhubzylinders in the alarm position (see Figure 2), the locking element 3 is unlocked by the piston rod 4 of the locking console 6 and the flap 2 is raised and pivoted, with only forces on the first axis of rotation P ₀ on the hinge of the flap and on the pivotable connection point P _{1 are introduced} into the flap, which is thus little burden. The kinematics of the arrangement of the flap 2 of the Doppelhubzylinders 5 of the support lever 8 and the reversing lever 9 is formed so that during the pivotal movement of the flap 2, the first pivot axis P ₅ of Doppelhubzylinders 5 about the stationary second pivot axis P _{3 of} the support lever 8 describes a circular path, which intersects with a circular path which describes the point P ₄ as the third pivot axis of the Doppelhubzylinders at one end of the reversing lever 9 about its stationary pivot axis P ₂ on the console 7. Segments of this circular path are shown in Fig. 3 with dotted lines.

As a first variant, which allows the joint arrangement according to the invention, it is assumed from Fig. 3 of a top frame with a bracket 11 which is located on the same side inside of the top frame on which above the first axis of rotation P _{0 of} the flap 2 is arranged so do not continuously extend from the area of this first axis of rotation P ₀ down as the console 7 in Figs. 1 and 2. on the other hand, a locking bracket is in the top frame 10 of FIG. 3 on the opposite side inside 12 extends downward.

It should be noted at this point that in all figures Matching parts bear the same reference numerals.

In the first variant of FIG. 3 is a support lever 13, whose central axis is shown with a dash-dot line, pivotally between a first pivot axis P ₅ in the central axis of the Doppelhubzylinders 5 as a linear drive element on the one hand and the stationary second pivot axis P ₃ , in the Console 11 is mounted below at a vertical distance from the first axis of rotation P ₀ , arranged. A likewise indicated only by its center line dash-dotted lever 14 is pivotable on the one hand about a third pivot axis P ₄ on the Doppelhubzylinder 5 and on the other hand about a fixed pivot point P ₂ below in the locking console 12th

When the double-stroke cylinder 5 is actuated, it in turn releases with its piston rod 4 a locking element 3 from the locking console 12 and pushes or pivots the flap 2 from the closed horizontal position into the wide-open alarm position of the flap 2 '. The kinematics in turn, as in the basic form so that the point P, a circle segment around the point P ₂ describes until the bellcrank is in the alarm position 14 '. Analogously, the point P ₅ , which represents the first pivot axis, describes a circular segment about the fixed second pivot axis P _{3 of} the support lever 13, which is designated in the alarm position by 13 '. Both circle segments intersect.

In the second variant of FIG. 4 is located within a top frame 15 on the opposite to the stationary first axis of rotation of the flap 2 side inside a console 16 which extends from an upper part designed for locking downwards, where in turn a fixed pivot point P. ₂ a reversing lever 17 is pivotally mounted. At its opposite end, the reversing lever 17 is in turn arranged on the third pivot axis P _{4 of} the Doppelhubzylinders as a linear drive element, and indeed at its end, which is opposite to the locking element 3.

A support lever 18 is further arranged from the end of the Doppelhubzylinders 5 about the first pivot axis of the Doppelhubzylinders P ₅ to a support lever 18 which is in the drawn basic position, the closed position of the flap 2, parallel to the Doppelhubzylinder. To the first pivot axis P ₅ opposite end of the support lever is mounted in a stationary second pivot axis P ₃ , which is here perpendicular to the fixed pivot point P _{2 of} the reversing lever in the console 16.

This embodiment is thus characterized by the fact that the console 16 opposite the inside of the attachment frame 15 no console or the like may be arranged must, to the reversing lever 17 or the support lever 18 at each store one end stationary. Nevertheless, the principle is Same kinematics with respect to the movement of the flap 2 in achieves the unillustrated wide open alarm position, as shown in Fig. 3.
