LINK MECHANISM FOR A DRIVING BAR FITTING

The invention concerns a link mechanism for a driving bar fitting for condition wings of douple swing Festern or doors without central posts. The driving bar fitting exhibits a Stulpschiene and a Treibstange lengthwise-mobile in addition. A control lever is tiltable by means of one the Stulpschiene assigned and perpendicularly to their longitudinal axis running stationary axis of rotation and propels the Treibstange with the help of a connecting lever. The connecting lever is swivelling in each case at a first camp with the control lever and connected at a second camp with the Treibstange.

Such link mechanism is for example well-known from the DE 202 13 937 U1. In it a link mechanism for a driving bar fitting with Stulpschiene, a Treibstange lengthwise-mobile in addition and a control lever is descriptive, whose axis of rotation of the Stulpschiene is assigned and runs perpendicularly to their longitudinal axis. The control lever propels the Treibstange over a connecting lever and is tiltable within the wing framework level. The connecting lever is in each case at the control lever and stored at the Treibstange swivelling. The connecting lever is connected with the Treibstange by a Gegenelement, at which the connecting lever is swivelling attached and which is bolted with the Treibstange.

With the well-known link mechanism it is unfavorable that assembly and/or transportation problems result. The Treibstange must itself when a assembling at the wing, in order not to collide with other fitting parts, rule in an turningopened position. The Treibstange is in turningopened position is swivelled however the control lever and stands from the Stulpschienenebene out. Being away the control lever from the remaining fitting leads again to transport difficulties.

Task of the invention is it therefore to arrange a link mechanism of the kind initially specified assembly and transport friendly.

This task is solved by the characteristics genanten in requirement 1. The link mechanism according to invention is operated with a control lever. The control lever is tiltable by means of one the Stulpschiene assigned and perpendicularly to their longitudinal axis running stationary axis of rotation and propels a Treibstange with the help of a connecting lever. The connecting lever is swivelling in each case at the first camp with the control lever and connected at the second camp with the Treibstange. The connection between the control lever and the Stulpschiene at the stationary axis of rotation or between the control lever and the connecting lever at the first camp or between the connecting lever and the Treibstange at the second camp are decouplable, so that the control lever does not stand with the Treibstange in drive connection. The connection between the control lever and the Stulpschiene at the stationary axis of rotation continue to be producible or between the control lever and the connecting lever at the first camp or between the connecting lever and the Treibstange at the second camp by manipulation of the control lever, so that the control lever with the Treibstange is located in drive connection. Thus the control lever stands in a distribution position, before manipulation of the control lever, not with the Treibstange in drive connection, so that the Treibstange is despite closed, parallel to the Treibstange running control lever into turningopened position, what facilitates an assembly to used conditions made possible and transport. The drive connection remains existing after manipulation of the control lever, so that the drive of the Treibstange is permanently granted by swivelling of the control lever.

With the link mechanism according to invention it is intended that with manipulation of the control lever - after assembly of the driving bar fitting - which is producible connection between the connecting lever and the Treibstange at the second camp between a first opening at the connecting lever and a Gegenelement at the Treibstange.

The drivingbar-lateral Gegenelement exhibits an axle, the axle taking up retaining support and a retaining foot, whereby the retaining foot is firmly connected with the Treibstange and so one expenditure-practiced on the control lever Kraft to the Treibstange transfers.

Further it is intended that after manipulation of the control lever the first opening of the connecting lever cooperates with the axle of the Gegenelements. The connecting lever moves with manipulation of the control lever ever on the Gegenelement to the connecting levers finally with its first opening the axle of the Gegenelements continues to embrace.

The permanent drive connection between control levers and Treibstange becomes particularly simple, if the connecting lever at the first camp exhibits a spring element, which links the connecting lever up toward the drivingbar-lateral Gegenelements and/or the Treibstange. Thus an inadvertent loosening of the drive connection between control levers and Treibstange is effectively prevented.

In accordance with another favourable further training of the link mechanism the connecting lever at the first opening exhibits at least one fixed bracket, which cooperates with the axle of the drivingbar-lateral Gegenelements. After slots at least a fixed bracket of the connecting lever with the axle a permanent drive connection between control levers and Treibstange is ensured.

The connecting lever continues to exhibit a second opening, in which the axle of the drivingbar-lateral Gegenelements in the distribution position and/or before manipulation of the still closed control lever rests, so that the control lever does not exceed over the Stulpschienenebene and no transport difficulties caused.

Another execution form plans that the control lever is kept additional by a magnet in its closed position. The magnet cooperates with the metallic Stulpschiene and is attached at one the Stulpschiene turned side of the control lever.

On the basis the following design the invention is more near described.

Figure 1 shows two driving bar fittings 1 and 11, whereby the driving bar fitting 1 is assigned to a not represented main wing and the driving bar fitting 11 a likewise not represented condition wing of a douple swing window without central posts. The driving bar fitting 1 exhibits a transmission 2, which propels a Treibstange 6 over a not represented grasp olive and over connection points 5 with a first hitting a corner detour 3 and is connected for a second hitting a corner detour 4. At the hitting a corner detours 3 and 4 can, as in Fig. 1 not more near shown, further fitting components attached its. The driving bar fitting 11 exhibits a link mechanism 12, which is connected by connection points 15 with a Treibstange 16 and propels these. The driving bar fitting continues to have 11 a third hitting a corner detour 13 and a fourth hitting a corner detour 14, which can be likewise attached to further fitting components.

In figure 2 a cut is represented by the link mechanism 12 in its distribution position, in which the control levers 20 tiltable around the stationary axis of rotation 21 is closed, the Treibstange 16 however in turningopened position is. This is reached, as the control lever 20 and the Treibstange 16 are not drive-connected in the distribution position. The control lever 20 can be connected by a connecting lever 40 with the Treibstange 16. An end of the connecting lever 40 is swivelling stored at the control lever 20 at a first camp 41. The other end of the connecting lever 40 is with the Treibstange 16 at a second camp 42 linked, as a first opening is brought to 43 of the connecting lever 40 with an axle 46 in interference. In the distribution position the Treibstange 16 and the control lever 20 are not coupled and the axle 46 connected with the Treibstange 16 by the retaining foot 48 lie in a second opening 45 of the connecting lever 40. The second opening 45 is in such a way arranged at the connecting lever 40 that the Treibstange 16 is in this position in turningopened position. The connecting lever 40 is taken up partial in a recess of a Stulpschiene 17 and inside the control lever 20 and rests upon flat the Treibstange 16, parallel to the control lever 20.

In figure 3 the use of the control lever 20, represented shortly before production of the drive connection between control lever 20 and Treibstange 16, is in the side view. After a loosening of the control lever 20 from its closed position with the help of a release mechanism 30 the connecting lever 40 slides when swivelling the control lever 20 along the Treibstange 16 to its an end with the first opening 43 onto the axle 46 pushes and with this in interference is brought, whereby the Treibstange 16 with the control lever 20 is drive-connected.

As represented in the side view of the link mechanism 12 in figure 4, by the swivelling of the control lever 20 and the spring action of the spring element 49 expenditure-practiced on the connecting lever 40 is pressed toward the Treibstange 16 the axle 46 into the first opening 43 of the connecting lever 40 covered here and makes so the drive connection between the control lever 20 and the Treibstange 16. With the coupling a swivelling connection between the Treibstange and the connecting lever 40 given 16 at the second camp 42 is. A swivelling of the coupled control lever 20 affects over the connecting lever 40 and the Gegenelement 46, 47, 48 the Treibstange 16 and shifts these depending upon swiveling direction of the control lever 20 in or other direction. The axle 46 taking up retaining support 47 is by the retaining foot 48 not visible in the side view firmly with the Treibstange connected.

The cut by the link mechanism 12 points to figure 5 that the retaining support 47 with this, connected by the retaining foot 48 with the Treibstange 16, moves firmly within a recess in the Stulpschiene 17. The axle 46 stands in interference with the first opening 43 of the connecting lever 40. The spring element 49 links the connecting lever 40 toward to the Treibstange up 16. Additionally fixed brackets 44 appropriate at the first opening 43 are, which 46 with the first opening 43 lets the axle rest. With closed control lever 20 the connecting lever 40 and the retaining support 47 completely sunk inside the control lever 20 lie. The Treibstange 16 is not as in the figures 2 to 4 in the turningopened separates now in a locked position. In order to keep the control lever 20 additional in its closed position, with the Stulpschiene 17 cooperating magnet 22 is attached at one the Stulpschiene 17 turned side of the control lever 20. The coupling between Treibstange 16 and connecting lever 40 at the first camp 41 can be solved with certain energy expenditure again. This is however not necessary under normal conditions.
