    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0064] FIG. 1 illustrates a casement arrangement 1 having a window casement 2. The casement 2 is mounted in a pivotable manner on a frame 3. For the purposes of opening and closing the casement 2, use is made of a handle 4, which can be rotated through 90° or 180° from the vertically oriented position illustrated, The handle 4 interacts with a fitting-gear mechanism (not illustrated), which in turn interacts with a fitting 5. The casement 2 has an all-round frame profile 6, which has a C-shaped casement groove 7 which is open in the direction of the frame 3. The casement groove 7 is arranged in the rebate at the frame profile 6 of the casement 2.

    [0065] In the exemplary embodiments illustrated, the fitting 5, which can be located at one or more locations in the rebate of the frame profile 6 of the casement 2, has at least one fitting part in the form of at least one drive rod 8. The exemplary embodiments according to FIGS. 2 and 6 to 12 provide a further fitting part in the form of a closing mechanism 9, whereas FIGS. 13-35 illustrate a corner deflection means 10.

    [0066] The fact that the further fitting part may also be designed in the form of a tilt-locking device or a scissor mechanism is not illustrated. What is said here in relation to the closing mechanism 9 and/or to the corner deflection means 10 therefore also applies to other fitting parts with fundamentally different functions and designs. To this extent, what is said hereinbelow in relation to the drive rod 8 and/or the closing mechanism 9 and/or the corner deflection means 10 also relates to other possible fitting parts, which are usually arranged in the casement groove 7 in the rebate of the frame profile 6, even if these other fitting parts are not indicated specifically hereinbelow.

    [0067] The drive rod 8 has an elongate, flat main body 11 with a front side 12 and a rear side 13. In the installed state, the rear side 13 is directed towards the base 14 of the casement groove 7, The front side 12 of the main body 11 is directed into the rebate or towards the frame 3. On opposite longitudinal sides 15, 16, the main body 11 has a first peripheral region 17 for engaging behind a limb 18 of the C-shaped casement groove 7 and a second peripheral region 19 for engaging behind a further limb 20 of the casement groove 7. The groove limbs 18, 20 have their free ends oriented towards one another.

    [0068] The essential factor in conjunction with the drive rod 8 is then, first of all, that the front side of the main body 11 has provided on it two spaced-apart angled limbs 21, 22, of which the free ends are directed towards one another. The angled limbs 21, 22, which—as seen in cross section—may also, in principle, be of arcuate design, since ultimately the only important thing is for an undercut to be formed by each of the angled limbs 21, 22, form a C-shaped groove 23 on the main body 11, which is provided for the insertion of the further fitting part into the groove 23.

    [0069] In addition to the angled limbs 21, 22, the main body 11 has, on the two longitudinal sides 15, 16, a peripheral limb 24, 25 projecting on the front side, wherein the peripheral limbs 24, 25 are provided for engaging behind a limb 18, 20 of the casement groove 7. It is ultimately the case that the longitudinal sides 15, 16 of the main body 11 are angled in order to form the peripheral limbs 24, 25. This means that two angled limbs 21, 22 and two peripheral limbs 24, 25 are located on the front side 12 of the main body 11. A limb groove 26, 27 is formed here in each case between the angled limb 21 and the peripheral limb 24 and between the angled limb 22 and the peripheral limb 25.

    [0070] An elevation 28 is located on the main body 11, between the two angled limbs 21, 22. A free space 29 is provided on the underside, in the region of the elevation 28. In the region of the elevation 28, the wall thickness of the main body 11 is the same as in the non-elevated region. It is always the case that the main body projects from the base 14 of the casement groove 7 in the region of the elevation 28, while otherwise the rear side 13 of the main body 11 butts against the base.

    [0071] As can also be gathered from various figures, the main body 11 is of mirror-symmetrical design in relation to its centre longitudinal axis M.

    [0072] The closing mechanism 9 and also the corner deflection means 10, as a further fitting part, each have a connection body 30, which has a rear side 31 and a front side 32. The rear side of the connection body 30 has located on it a foot 33 with opposite engagement protrusions 34, 35, which are provided for engaging in the groove 23 between the angled limbs 21, 22. It is also the case that, on its opposite longitudinal peripheries, the connection body 30 has a respective limb 36, 37 which is angled on the rear side, wherein the limbs 36, 37 are each designed for arranging in the respective limb groove 26, 27 between the respective peripheral limb 24, 25 and the adjacent angled limb 21, 22.

    [0073] Furthermore, the connection body 30 has provided in it a screw-connection through-opening 38 for a punching screw 39. This screw-connection serves for fixing the further fitting part on the drive rod 8.

    [0074] It is also the case that the connection body 30 has a respective protrusion 42, 43 on the two end sides 40, 41. Each of the protrusions 42, 43 is of wedge-shaped design in two respects, that is to say, on the one hand, in and counter to the longitudinal direction of the connection body 30. In this case, the two protrusions 42, 43 taper towards their free ends. Furthermore, it is nevertheless also the case that the protrusions 42, 43 are each provided with a slope 44 on the underside. The protrusions 42, 43 assist the arrangement and correct orientation of the further fitting part on the drive rod 8. In addition, the foot 33, the limbs 36, 37, the screw-connection opening 38 and/or the protrusions 42, 43 of the connection body 30 are mirror-symmetrical.

    [0075] The operation of installing the drive rod 8 in the frame profile 6 is illustrated in FIGS. 3 to 5. The drive rod 8 is installed frontally and, for this purpose, is inserted obliquely into the casement screw 7. In the exemplary embodiment illustrated, the peripheral region 19 is inserted obliquely into the groove portion 45, which is formed by the groove limb 18, as is illustrated in FIG. 4. However, it is also possible, in principle, for the drive rod 8 to be inserted into the groove portion 46 via the other peripheral region 17 and then, unlike the situation illustrated in FIG. 4, pivoted in. The groove opening 47, which is provided between the free ends of the groove limbs 18, 20, has a width b, which is smaller than the width B of the drive rod 8. However, the distance A between the groove base of the groove portion 45 and the groove base of the groove portions 46 is greater than the width B of the drive rod 8. These size ratios ultimately make it possible for the drive rod 8, once placed in position in a groove portion 45, 46, to be pivoted into the casement groove 7, as is illustrated in FIG. 5.

    [0076] It is usually following installation of the drive rod 8 in the manner described above that the closing mechanism 9 is inserted into the casement groove 7. The closing mechanism 9 here is placed alongside the drive rod 8, as is illustrated in FIG. 6. The operation of inserting the closing mechanism 9 into the opening 47 of the casement groove 7 requires the distance between the outer sides of the limbs 36, 37 to be equal to or smaller than the width b of the groove opening 47. Once the closing mechanism 9 has been inserted into the casement groove 7, the closing mechanism 9 is displaced in the direction of the drive rod 8, as is illustrated in FIG. 6. In contrast to the position illustrated in FIG. 6, the drive rod has the peripheral limb 25 resting on the groove base of the groove portion 45, as is shown in FIG. 5. When the closing mechanism 9 is displaced in the direction of the drive rod 8, the protrusion 42 penetrates into the groove 23 and raises the same within the casement groove 7 and centres the drive rod 8 in the casement groove 7. The slope 44 on the underside of the protrusion 42 makes it easier for the closing mechanism 9 to run onto the drive rod 8. The closing mechanism 9 is then pushed into the desired position on the drive rod 8. This is illustrated FIG. 7. In this state, the limbs 36, 37 of the connection body 30 engage in the limb grooves 26, 27 of the main body 11. Moreover, the foot 33 has its engagement protrusions 34, 35 located in the groove 23, wherein the engagement protrusions 34, 35 engage behind the angled limbs 21 and 22. This is shown in FIGS. 8 and 9.

    [0077] The closing mechanism 9 is then fixed on the drive rod 8 by virtue of the punching screw 39 being tightened, as can be gathered from FIGS. 10 to 12. In particular FIG. 12 shows that the punching screw 39 passes through the main body 11 by way of its end-side punching extension, and this gives rise to a fixed connection between the drive rod 8 and the closing mechanism 9 in the region of the screw-connection. Punching residues which are produced during the punching operation are accommodated in the free space 29 of the main body 11.

    [0078] It should be noted that it is also possible, in principle, for the closing mechanism 9, rather than being arranged laterally alongside the drive rod 8 and then being pushed onto the drive rod 8, to be placed in position directly on the drive rod 8, the foot 33 being inserted into the groove 23, and the limbs 36, 37 being inserted into the limb grooves 26, 27, in the process.

    [0079] FIGS. 13-35 illustrate part of a frame profile 6, drive rods 8 which are to be placed in position and a corner deflection means 10. The corner deflection means 10 has a main body 48, which has a first corner limb 49 and a second corner limb 50. The two corner limbs 49, 50 are at right angles to one another. The corner deflection means 10 also has two end-side connection bodies 30. The connection bodies 30 are constructed in functional terms in the same way as the closing mechanism 9. To this extent, reference is made expressly to what has been said above. The two connection bodies 30 are connected to one another via at least one leaf spring 51. In the case of the embodiments illustrated, three leaf springs 51 are provided for the purpose of transmitting the tensile forces and shear forces. The connection bodies 30 can be moved relative to the main body 48.

    [0080] In particular with reference to FIGS. 31 to 33, the corner limbs 49, 50 have an undercut 53 on their first longitudinal side 52. The undercut 53 gives rise to a groove 54 for a limb 20 of the casement groove 7.

    [0081] The essential factor in conjunction with the corner deflection means 10, then, is that that region of the second longitudinal side 55 of the first and of the second corner limbs 49, 50 which is located opposite the undercut 53 of the first longitudinal side 52 is undercut-free. The fact that the second longitudinal side 55 is free of undercut here means, in particular, that there is no effective undercut provided there which engages behind the limb 18 of the casement groove 7 in the installed state of the corner deflection means 10.

    [0082] In addition, a securing means 56 is provided on the second longitudinal side 55. The securing means 56 can be moved relative to the second longitudinal side 55, and therefore relative to the main body 48, between a securing position, as is illustrated, for example, in FIG. 33, and a disengagement position, as is illustrated, for example, in FIG. 32. In order to simplify matters, not all the details of the main body 48 as such have been illustrated in the cross-sectional illustrations of FIGS. 31 to 33.

    [0083] The securing means 56 is a pivotably mounted pivot lever with a securing portion 57. The pivot lever is mounted in the corner region 58 of the first and second corner limbs 49, 50 such that it can be pivoted via a pivot-mounting means 59. It is also the case that, in addition to the securing portion 57, the securing means 56 has a stop 60 for delimiting the pivoting movement. The front side 61 of the associated corner limb 49 or of the main body 48 has provided on it a holder 62 in the form of a recess for the stop 60. In the pivoted-in state, that is to say in the securing position, the outer side of the stop 60 is flush with the front side 61 of the main body 48, as can be gathered, in particular, from FIG. 33.

    [0084] Also provided is an arresting means 63 for arresting the pivot lever in the securing position. In specific terms, the arresting means 63 is designed in the form of a latching connection, wherein the second longitudinal side 55 has provided on it a latching protrusion 64 for interacting with a latching opening 65 in the securing portion 57. It should be noted that, even if it projects from the second longitudinal side 55, the latching protrusion 64 has nothing to do with an undercut in the sense of the invention, since the latching protrusion 64 projects on a region of the second longitudinal side 55 which is not provided for insertion into the casement groove 7 and therefore cannot interact with the groove limb 18.

    [0085] As can also be gathered from FIGS. 31 to 33. the width b of the opening 47 of the casement groove 7 is slightly greater than or equal to the distance between the first longitudinal side 52 and the second longitudinal side 55 in the region of the undercut 53. It should be noted that the distance relates to that region of the longitudinal sides 52, 55 which is provided for insertion into the casement groove 7. In addition, the depth T of the limb groove 54 of the main body 48 or of the respective corner limb 49, 50 is greater than or equal to the thickness D of the securing portion 57 of the pivot lever.

    [0086] The operations of inserting the corner deflection means 10 and connecting it to the drive rods 8 will be described in more detail hereinbelow. Proceeding from the situation illustrated in FIG. 13, first of all the drive rods 8 are inserted in the manner described above. This state is illustrated in FIG. 14. The corner deflection means 10 is then placed in position at the corner of the frame profile 6. Since the relevant contours of the two corner limbs 49, 50 are of identical design, it is possible for first the one corner limb or for first the other corner limb to be pushed on or else for the two corner limbs 49, 50 to be pushed on at the same time. FIG. 31 depicts the arrangement of the corner deflection means immediately prior to insertion into the casement groove 7, whereas FIG. 32 shows the main body 48 inserted into the casement groove and already displaced therein.

    [0087] Following insertion into the casement groove 7, the main body 48 is displaced in the direction of the groove limb 20 in accordance with the arrow direction indicated in FIG. 32. The groove limb 20 then engages in the limb groove 54, wherein the undercut 53 engages behind the groove limb 20. This gives rise, in the region of the second longitudinal side 55, to a form fit between the main body 48 and the groove limb 20 in the removal direction of the corner deflection means 10. Moving the main body 48 following insertion into the casement groove 7 gives rise to an interspace 66 between the second longitudinal side 55 and the limb 18 of the casement groove 7. The pivot lever has its securing portion 57 pivoted from the disengagement position into the securing position in said interspace 66, as is illustrated in FIGS. 19 and 33. The gap width of the interspace 66 here is equal to or slightly greater than the thickness D of the securing portion 57. In the secured state, the corner deflection means 10 cannot be pushed or raised out of the casement groove 7, nor can it be tilted out of the same. Removal of the corner deflection means 10 from the casement groove 7 by being pushed out is ultimately prevented by the undercut 53 provided on the two corner limbs 49, 50, while the tilting-out or raising action is prevented by the pivoted-in securing portion 57.
