DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(11) A fitting unit 1 shown in FIGS. 1a, 1b, 1c forms a fitting assembly 4 together with a spacer 2 shown in FIGS. 2a, 2b, 2c, or a spacer 3 shown in FIGS. 3a, 3b.

(12) The fitting unit 1 comprises a fixed-frame-side support bracket 5, a sash-side support bracket 6 and a scissor-assembly 7 provided between the fixed-frame-side support bracket 5 and the sash-side support bracket 6.

(13) The fixed-frame-side support bracket 5 has a bearing leg 8 and an additional support-bracket leg 9 which is riveted to the bearing leg 8. Moreover, a guiding contour 10 is riveted to the bearing leg 8 of the fixed-frame-side support bracket 5. Instead of the riveted connections provided in the exemplary case shown, for example screwed connections are also conceivable between the individual components of the fixed-frame-side support bracket 5.

(14) The sash-side support bracket 6 is composed of a bearing leg 11 and an additional support-bracket leg 12 riveted thereto. On the side of the bearing leg 11 pointing toward the guiding contour 10 of the fixed-frame-side support bracket 5, the bearing leg 11 of the sash-side support bracket 6 is provided with a sash guiding element in the form of a guiding protrusion 13.

(15) The scissor-assembly 7 comprises Y-scissors 14 and a link 15 as scissor elements. The Y-scissors 14 are formed by scissor elements in the form of a long scissor arm 16 and short scissor arm 17.

(16) The long scissor arm 16 and the short scissor arm 17 of the Y-scissors 14 as well as the link 15 of the scissor assembly 7 are mounted on the bearing leg 8 of the fixed-frame-side support bracket 5 so as to be able to rotate about rotation axes that are perpendicular to the drawing plane in FIG. 1c. The rotary bearing of the long scissor arm 16 of the Y-scissors 14 is stationary in the longitudinal direction of the bearing leg 8. In contrast thereto, the rotary bearing points of the short scissor arm 17 of the Y-scissors 14 and of the link 15 provided on the bearing leg 8 of the fixed-frame-side support bracket 5 are provided on a slider 18, which is movably guided along the bearing leg 8 in the longitudinal direction thereof. In this instance, the slider 18 engages, by means of longitudinal edges extending in the movement direction, behind associated longitudinal edges of the bearing leg 8 having a C-shaped cross-section. By actuation of a brake screw 19 rotatably guided on the slider 18, as is known, the motion resistance may be adjusted, which counteracts the movement of the slider 18 along the bearing leg 8.

(17) To the bearing leg 11 of the sash-side support bracket 6, the link 15 and the long scissor arm 16 of the scissor-assembly 7 are rotatably connected by means of stationary rotary bearings. A stationary sash-side rotary bearing of the short scissor arm 17 is arranged on the long scissor arm 16 of the Y-scissors 14 between the rotary bearings at the ends of the long scissor arm 16.

(18) The spacer 2 shown in FIGS. 2a, 2b, 2c has a base body 20 substantially having the shape of a cuboid with a protrusion 21 on the upper end in FIG. 2a. The protrusion 21 is provided on the downward-facing side thereof with a receiving channel 22, and a semi-circular cut-out 23. The width of the receiving channel 22 on the spacer 2 is slightly less than the thickness of the additional support-bracket leg 9 of the fixed-frame-side support bracket 5 and the thickness of the additional support-bracket leg 12 of the sash-side support bracket 6. Due to the cut-out 23 on the protrusion 21 of the spacer 2, a cylindrical passage opening 24 provided on the base body 20 of the spacer 2 is accessible in the axial direction of the passage opening 24 for a fixing screw not shown in FIGS. 2a, 2b, 2c. A further passage opening 25 for a fixing screw is provided on the base body 20 of the spacer 2 at a distance from the cylindrical passage opening 24. The passage opening 25, contrary to the passage opening 24, is formed as an oblong hole.

(19) A passage opening 26 is arranged on the base body 20 of spacer 2 between the passage opening 24 and the passage opening 25, which opening 26 is provided with an internal thread, in which an adjustment element in the form of an adjustment screw 27 engages. The adjustment screw 27, designed as a headless screw, is provided at one longitudinal end with an internal hexagon, which is used for engagement of an actuating tool.

(20) The spacer 3 according to FIGS. 3a, 3b constructively substantially corresponds to the spacer 2 of FIGS. 2a, 2b, 2c. Unlike the spacer 2, the profile of a lower corner on the spacer 3 is rounded and the base body 20 is provided with an extension 29 so as to form a recess 28.

(21) FIGS. 4 to 7b show the fitting assembly 4 in the installed state.

(22) According to FIG. 4, the fitting assembly 4 is positioned on a window 30 between a fixed frame 31 and a sash 32. The sash 32 opens outwards.

(23) When opening and closing the sash 32, said sash performs a rotational motion about a rotation axis which is vertical in FIG. 4, and also a translational motion, which is perpendicular to a main plane 33 of the fixed frame 31 indicated in FIG. 4. The sash 32 is guided by the fitting assembly 4 in such a way that the sash 32, and in particular a sash overlap 34, does not collide with the fixed frame 31.

(24) In the installed position of the fitting assembly 4, the fixed-frame-side support bracket 5 surrounds a fixed-frame corner 35 which is formed by a horizontal first fixed-frame rebate face 36 in FIG. 4 and a vertical second fixed-frame rebate face 37 in FIG. 4.

(25) The sash-side support bracket 6 surrounds a sash corner 38 of the sash 32, at which corner a horizontal first sash rebate face 39, which is provided in FIG. 4 on the downwardly facing side of sash 32 and is therefore not visible, and a vertical second sash rebate face 40 in FIG. 4 meet.

(26) The first fixed-frame rebate face 36 and the second fixed-frame rebate face 37 as well as the first sash rebate face 39 and the second sash rebate face 40 are formed as groove-free planar rebate faces.

(27) The fixed-frame-side support bracket 5 rests with the bearing leg 8 thereof on the first fixed-frame rebate face 36 and is screwed there to the fixed frame 31. Another screw connection between the fixed-frame-side support bracket 5 and the fixed frame 31 is provided on the additional support-bracket leg 9 of the fixed-frame-side support bracket 5. The additional support-bracket leg 9 of the fixed-frame-side support bracket 5 is supported by means of a spacer, in the illustrated example the spacer 3, on the second fixed-frame rebate face 37 of the fixed frame 31. The spacer 3 is plugged onto the additional support-bracket leg 9. The free end of the additional support-bracket leg 9 engages in the receiving channel 22 provided on the spacer 3. Due to the slight excess of the thickness of the additional support-bracket leg 9 relative to the width of the receiving channel 22, a detachable clamping connection is produced between the spacer 3 and the additional support-bracket leg 9. In addition, the receiving channel 22 forms a positioning element and in this respect provides for a defined arrangement of the spacer 3 on the additional support-bracket leg 9 of the fixed-frame-side support bracket 5.

(28) When the spacer 3 is mounted on the additional support-bracket leg 9, the passage openings 41, 42 and a further opening 43, which are all provided on the additional support-bracket leg 9 of the fixed-frame-side support bracket 5, are aligned with the passage openings 24, 25, 26 on the spacer 3. In order to secure the additional support-bracket leg 9 to the second fixed-frame rebate face 37, fastening screws 44, 45 are used as fastening elements and screwed into the fixed frame 31 through the paired aligned passage openings 41, 24; 42, 25 on the additional support-bracket leg 9 and on the spacer 3. The opening 43 on the additional support-bracket leg 9 allows access to the adjusting screw 27, which is received on the spacer 3 in the passage opening 26 thereof. By means of the adjusting screw 27, the fixed-frame-side support bracket 5, before being screwed to the fixed frame 31, is finely adjusted with respect to the fixed frame 31 perpendicularly to the second fixed-frame rebate face 37 and the additional support-bracket leg 9 extending in parallel therewith.

(29) The thickness of the spacer 3 between the side of the additional support-bracket leg 9 of the fixed-frame-side support bracket 5 facing the second fixed-frame rebate face 37 on the one hand and the second fixed-frame rebate face 37 on the other hand corresponds to the extent of the projection, by which the guiding contour 10 protrudes, on the side of the additional support-bracket leg 9 facing the second fixed-frame rebate face 37, with respect to said additional support-bracket leg towards the second fixed-frame rebate face 37. As a result, the spacer 3 on the additional support-bracket leg 9 can ensure planar support of the fixed-frame-side support bracket 5 on the fixed frame 31. The projection of the guiding contour 10 is located on the spacer 3 within the recess 28 delimited on one side by the extension 29.

(30) The sash-side support bracket 6 is screwed to the sash 32 through the bearing leg 11, which is covered in FIG. 4, on the first sash rebate face 39, also not visible in FIG. 4, and through the additional support-bracket leg 12 on the second sash rebate face 40. The bearing leg 11 rests directly on the first sash rebate face 39, the additional support-bracket leg 12 rests directly on the second sash rebate face 40. Fastening elements in the form of fastening screws 46, 47 pass through passage openings 48, 49 on the additional support-bracket leg 12. An opening 50 on the additional support-bracket leg 12 is not used in the installation conditions according to FIG. 4. The guiding projection 13 on the bearing leg 11 of the sash-side support bracket 6 protrudes on the side of the additional support-bracket leg 12 facing the fixed-frame-side guiding contour 10 and interacts during the final phase of the closing movement of sash 32 with the guiding contour 10 such that the sash 32 can reach the closed position thereof against the fixed frame 31 in a collision-free manner.

(31) The installation conditions shown in FIGS. 5a, 5b on the window 30 substantially correspond to those of FIG. 4. Unlike FIG. 4, in FIGS. 5a, 5b, a fitting groove 51 extending in the peripheral direction of the sash 32 is provided only on the second sash rebate face 40. The additional support-bracket leg 12 of the sash-side support bracket 6 has a width perpendicular to a main plane 52 of the sash 32 in FIG. 5a, which is larger than the opening width of the fitting groove 51. Thus the additional support-bracket leg 12 of the sash-side support bracket 6 is able to be mounted on the second sash rebate face 40 so as to cover the fitting groove 51 resting on the outside thereof. To this end, the fastening screws 46, 47 are screwed through the passage openings 48, 49 on the additional support-bracket leg 12 of the sash-side support bracket 6 into the groove base of the sash-side fitting groove 51.

(32) Unlike FIGS. 4 and 5a, 5b, FIGS. 6a, 6b and 7a, 7b show a window 30 having a fixed frame 31, the second fixed-frame rebate face 37 of which is provided with a fitting groove 53 extending in the circumferential direction of the fixed frame 31. The second sash rebate face 40 of the sash 32 is configured in FIGS. 6a, 6b as a groove-free planar surface and in FIGS. 7a, 7b it is provided with a fitting groove 51.

(33) The fitting groove 53 on the second fixed-frame rebate face 37 receives the projection of the guiding contour 10 on the fixed-frame-side support bracket 5. As a result, the additional support-bracket leg 9 of the fixed-frame-side support bracket 5 may rest flat directly on the second fixed-frame rebate face 37.

(34) On the sash side, the spacer 3 in FIGS. 6a, 6b and 7a, 7b is arranged on the side of the additional support-bracket leg 12 of the sash-side support bracket 6 facing the second sash rebate face 40. The additional support-bracket leg 12 of the sash-side support bracket 6 screwed to the sash 32 is supported in a planar manner on the second sash rebate face 40 by means of the spacer 3, it being possible to mount the spacer 3 in FIGS. 7a, 7b on the sash-side fitting groove 51 so as to rest on the outside, since the width of the spacer 3 perpendicular to the main plane 52 of the sash 32 is larger than the opening width of the fitting groove 51 on the second fixed-frame rebate face 40.

(35) The width of the rebate clearance, i.e. the width of the gap formed between the second fixed-frame rebate face 37 and the second sash rebate face 40, when the sash 32 is closed, is the same in all installation conditions shown in FIGS. 4 to 7b.
