Definitions

• the object of the invention relates to a tilt and turn fitting according to the preamble of claims 1 and 12.
• a relief element is attached to the frame or sash, which engages over or under a support part attached to the sash or frame during the closing process, so that the sash in the closing movement is supported on the swivel lever and rotates about its swivel axis with it.
• the pivot lever slightly raises the sash of the window or door and relieves the hinges of the sash.
• the sash is closed or tilted, it is supported on the fixed frame via the swivel lever, so that the sash only loads the hinges in its pivoted opening position.
• An embodiment of DE 41 17407 A1 provides that the swivel arm is articulated on its swivel axis in a substantially longitudinally movable manner and interacts with guide contours when swiveling by means of a guide pin.
• the guide contours are fixedly attached to a fastening part on which a pin for forming the Swivel axis is provided.
• the swiveled-out pivot lever engages via a lever mounted coaxially to the pivot axis in a drive rod running below in a faceplate of the connecting rod fitting. If the sash is aligned almost parallel to the frame, the swivel lever is aligned approximately parallel to the faceplate of the espagnolette fitting while the locking lever releases the espagnolette.
• a special design is provided which allows the pivoting lever to be adjusted in the longitudinal direction.
• the pivot axis of the pivot lever is made in an eccentric pin, the rotation of which simultaneously changes the effective length of the pivot lever.
• the locking lever In order not to influence the function of the shift lock, which would be inevitable with a direct coupling of the axis of rotation to the locking lever, the locking lever is mounted in an elongated hole in the pivot lever, so that it is fixed relative to the drive rod, even if the pivot lever itself the eccentric rivet is adjustable.
• Swivel arm and its length depends.
• the height that the wing is lifted by the relief element is determined from the difference in the heights of the contact surface, which it assumes in the swung-out and in the swung-in state - that is, with the wing closed.
• the object of the invention is therefore to improve the turn-tilt fitting according to the preamble of claim 1 so that on the one hand with the same or improved function of the turn-tilt fitting, the disadvantages inherent in the prior art are eliminated, in particular the ease of adjustment with a large possible stroke and can be realized in a small size.
• the turn-tilt fitting should be simple in its construction.
• additional restoring elements in the form of spring elements for deflecting the pivoting lever can be dispensed with, since the contact pressure of the tappet on the cam track can in each case cause a restoring force of the pivoting lever into a desired position.
• the plunger is generally force-loaded in the direction of the cam track in general by a spring member, gravity or similar devices, so that the contact between the plunger and cam track is guaranteed at all times.
• the cam track forms two contour sections of different inclinations.
• the lifting movement of the relief element can be adapted to the movement of the wing in terms of force and movement. If, for example, the plunger is initially assigned a steeper and then a flatter contour section during the closing process of the leaf, the plunger will cause a large stroke of the plunger and thus a large lifting movement of the leaf at the beginning of the closing process or the interaction of the contact part and the opposite, which in the transition to the flatter contour section, there is only a slight increase in the wing.
• a simple embodiment provides that the cam track is arranged on a lifting piece that is adjustable along a plate or rail that forms the mounting of the pivoting lever.
• the cam track can thereby be adapted to any manufacturing inaccuracies of the wing or frame or the arrangement of the relief element or the opposite.
• a particularly expedient and simple adjustment is possible if the lifting piece is supported against an eccentric approach of a bolt mounted in the plate or rail. Then, by rotating the bolt, the lifting piece resting against it can be shifted accordingly.
• the lifting piece has an edge contour which is assigned to the bolt and has a complementary shape to it. This can be done in the simplest Case correspond to a circular arc section, in which the bolt engages at least in sections - taking into account the mobility of the bolt caused by the eccentricity of the attachment.
• the lifting piece each has a constant arrangement transverse to the plate or rail with respect to the pivoting movement of the
• the lifting piece has a guide pin assigned to the plate or rail, which engages in a longitudinal recess of the plate or rail.
• the guide pin only allows longitudinal movements of the lifting piece relative to the plate or rail, so that even with an adjustment via the eccentric
• the lifting piece has a pin which is assigned to the pivoting lever and which extends through an opening of the pivoting lever through the pivoting lever limitation.
• the tappet is expediently provided with a semicircular contour at its end associated with the lifting piece, so that on the one hand it is possible to follow the tappet on or on the contour sections and at the same time the friction between the tappet and the contour section is minimized.
• a particularly space-saving design of the entire relief element is provided if the plunger has a longitudinally central recess in which an energy accumulator is received, which acts on the plunger in the direction of the lifting piece.
• the energy accumulator can optimally engage the plunger on the one hand and, on the other hand, does not lead to a larger structural volume of the relief element.
• the plunger and the pivoting lever are made of plastic as molded bodies. Such a production enables an equally inexpensive and precise mass production of the fitting parts, which - due to the advantages described in more detail above - ensure optimal force transmission even with high forces to be absorbed and thus enable the load-bearing capacity of the entire assembly.
• the swivel lever itself can form a plunger which is supported with its end assigned to the swivel axis on a cam track.
• essentially the entire pivot lever is moved on its longitudinal axis during pivoting, which is a simplification compared to the embodiment according to claim 1, but on the other hand also requires a certain additional installation space, since the pivot lever can protrude beyond the pivot axis at its upper end.
• the pivot lever has a window that receives a cam having the cam track.
• the boundary edge of the window which is assigned to the cam, assumes a position inclined to the longitudinal axis of the pivot lever.
• the swivel lever can assume a greater or lesser effective length with respect to the opposite, depending on the swivel angle.

• the fastening takes place in such a way that the bolt 3 can be rotated relative to the plate or rail 4, it being possible for this to be done via a tool engagement 15 arranged in the bolt 3.
• the pivot lever 2 has a shoulder 16 in the bore 10, the height 17 of which approximately corresponds to the thickness 18 of the head 11, so that it is received without protruding.
• the head 11 rests on the shoulder 16, so that the pivot lever 2 is pivotally but axially secured.
• the diameter 19 of the bore 10 is dimensioned somewhat larger than the dimension 20 of the oval extension 12 of the bolt 3.
• the bolt 3 can be rotated relative to the pivot lever 2 without this changing its position relative to the plate or rail 4. This is particularly the case because the pin 13 extends coaxially to the head 11, while the center of the oval attachment 12 is eccentric to the central axes of the pin 13 or the head 11.
• the lifting piece 9 has a pin 21 projecting in the direction of the pivoting lever, which is assigned to the pivoting lever 2 and engages in an opening 22 as a limitation of the pivoting angle.

• the lifting piece 9 has at its end opposite the contour 26 a cam track 27 which, with respect to the longitudinal axis 28 of the lifting piece 9 (which runs along the guide pin 25), forms two contour sections 29, 30 of different inclinations.
• the plunger 5 is accommodated in a longitudinally displaceable manner in the swivel lever 2 and is constantly subjected to force via a spring element 31 in the direction of the swivel axis or the lifting piece 9.
• the plunger 5 essentially has three sections, namely a contact part 32, a guide section 33 and a semicircular contour 34, as can be seen in particular from FIGS. 7 and 13.
• the guide section 33 has a longitudinally central recess 35 and two longitudinally extending edge recesses 36, 37.

It is provided in the embodiment according to FIGS. 1 to 6 that the plunger 5 has a greater distance 44 with increasing covering position of the longitudinal axis of the pivoting lever 2 and the plate or rail 4 than the distance 45 in the antiparallel position of the pivoting lever 2.
• the position and orientation of the contour sections 29, 30 can be used to influence the lifting of the wing independently of the length of the pivoting lever or the like.
• the lifting piece 9 is designed such that the wing is maximally raised in the parallel alignment position of the pivot lever 2 and plate or rail 4.
• the wing is again somewhat lowered in the completely closed state, in which the relief element 1 assumes the position shown in FIGS. 5 and 6, for example in order to simplify the interlocking of locking elements, but at the same time support the wing on the side of the wing opposite the hinge side.
• the position of the contour sections 29, 30 can be adjusted relative to the pivot lever 2 and thus to the plunger 5 via the bolt 3, so that when the torsion element 12 interacts with the edge contour 26 of the lifting piece 9, it is used to adjust the distance 44 becomes.
• the plunger 5 and the lifting piece 9 are formed asymmetrically along their central axis, which is attributable in particular to the finger-like projection 7 in the plunger 5.
• the plunger 5 can, however, be rotated through 180 ° due to its symmetrical arrangement with respect to the axis 46 (FIG. 13), and can be used both for right and left wing, whereby, of course, a corresponding alignment must take place before mounting the relief element 1.

• the bolt 3 overlaps the lifting piece at least in some areas, so that it cannot be removed from the plate or rail 4 after the bolt 3 has been inserted.
• the pivot lever 2 forms an approximately U-shaped cross section in a lower region 50. This is essentially caused by two side walls 51, 52, which form webs 53, 54 facing one another at the free end 6 of the pivoting lever 2.
• the webs 53, 54 act on the one hand to stabilize the side walls 51, 52 and on the other hand to limit the edges 55, 56 of the plunger 5, so that the plunger 5 until the edges 55, 56 abut the webs 53, 54 in is able to immerse the pivot lever 2.
• the side walls 51, 52 form a link guide with the guide section 33 of the plunger 2, so that the plunger 2 cannot tilt.

• the swivel lever 2 can be easily manufactured as a molded part made of plastic or the like, with its overall longitudinally symmetrical design and the associated usability for relief elements 1 for wings opening to the right and to the left ensuring advantageous capacity utilization during manufacture. Due to the fact that the lifting forces that occur are positively transmitted from the plunger 5 to the lifting piece 9, the pivoting lever 2 does not absorb any forces.
• the essentially positive and subsequent transmission of the weight forces of the wing that have to be borne and are to be carried over a wide contact surface also allow the tappet 5 and the lifting piece 9 to be made from a plastic which is preferably provided with friction-reducing components.

• a locking device for an espagnolette fitting can be provided on the pivot axis defined by the pin 3, as is known, for example, from DE 198 99 409 C1. Adjustment of the relief element 1 is possible without impairing the function of the shift lock, since the axis of rotation of the pivoting lever 2 is arranged in a stationary manner. In this case, the relief element 1 must be arranged on the wing, since the connecting rod fitting is usually attached here.
• the pivot lever 2 is also pivotably articulated on the plate or rail 4, but the lifting piece 9 is essentially symmetrical in relation to the longitudinal axis, so that two cam tracks 27, 27 'result.
• the lifting piece 9 is essentially designed in accordance with the lifting piece described in more detail above, but in this case the pin 21 or 21 ′ can be detached or disengaged from the opening 22 of the pivoting lever 2 to limit the pivoting angle of the pivoting lever 2.

• An essential advantage of the embodiment according to FIG. 14 is that the arrangement allows the relief element 1 to be used both with wings opening to the right and to the left. Therefore, the contact part 32 of the plunger 5 is also substantially longitudinally symmetrical. Deviating from this, however, it can also be provided that a contact part 32 provided with an extended projection 7 according to FIGS. 1 to 13 can be rotated about its longitudinal axis, so that the contact part 32 without dismantling can also be used both for right and left opening wings with the extended projection 7.
