DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0027] As shown in FIGS. 1 and 5, a window 1 designed as a sliding window comprises a fixed frame 2, a leaf 3 and a fitting assembly 4 arranged between the fixed frame 2 and the leaf 3. An upper horizontal frame member 5 of the fixed frame 2 and an upper horizontal frame member 6 of a leaf frame 7 of the leaf 3 are shown.

[0028] By means of the fitting assembly 4, the leaf 3 can be driven relative to the fixed frame 2 with a guided lifting-off movement in a lifting-off direction (arrow 8) perpendicular to a frame main plane 9 of the fixed frame 2 indicated by dash-dotted lines in FIGS. 1 and 5 and can thus be lifted off from a position close to the fixed frame (FIG. 1) to a position away from the fixed frame (FIG. 5). In addition, the fitting assembly 4 makes possible a horizontal shifting movement of the leaf 3 when it is in the position away from the fixed frame. A shifting direction 10 of the leaf 3 directed into the drawing planes of FIGS. 1 and 5 is indicated in FIG. 5 and extends perpendicular to the lifting-off direction 8 along the frame main plane 9.

[0029] To implement the above-mentioned functions, the fitting assembly 4 comprises a transverse guide 11, a lift-off drive 12, and a longitudinal guide 13.

[0030] The transverse guide 11 of the fitting assembly 4 is shown in detail in FIGS. 2 to 4 and 6 to 8.

[0031] FIGS. 2 to 4 show the transverse guide 11 in a first functional state of the fitting assembly 4, in which the leaf 3 assumes its position close to the fixed frame and is locked to the fixed frame 2. In FIGS. 6 to 8, the fitting assembly 4 and the transverse guide 11 are in a second functional state. In this second functional state of the fitting assembly 4, the leaf 3 is unlocked from the fixed frame 2 and is lifted off in a position away from the fixed frame in the lifting-off direction 8 relative to the fixed frame 2.

[0032] The transverse guide 11 of the fitting assembly 4 has a leaf-side transverse guide part 14 and a fixed-frame-side transverse guide part 15. The leaf-side transverse guide part 14 is screwed to the leaf 3 by means of four fastening screws 16 (FIG. 1). The fixed-frame-side transverse guide part 15 is provided with a guide roller 17 which can rotate about a roller rotation axis 18 extending parallel to the frame main plane 9. By means of the guide roller 17, the fixed-frame-side transverse guide part 15 is movably guided on a longitudinal guide path of the longitudinal guide 13 formed by a guide rail 19 in the shifting direction 10 of the leaf 3. The guide rail 19 is connected to the fixed frame 2.

[0033] Transverse edges 20 of the fixed-frame-side transverse guide part 15 extending in the lifting-off direction 8 are overlapped by the leaf-side transverse guide part 14 screwed to the leaf 3. Due to the resulting dovetail-like guidance, the leaf-side transverse guide part 14 and with it also the leaf 3 are movably guided in the lifting-off direction 8 on the fixed-frame-side transverse guide part 15.

[0034] A spring element is arranged between the leaf-side transverse guide part 14 and the fixed-frame-side transverse guide part 15, which spring element in the case of the fitting assembly 4 according to FIGS. 1 to 8 is designed as a helical spring 21.

[0035] A screw axis 22 of the helical spring 21 extends perpendicular to the frame main plane 9. The helical spring 21 is mounted with one axial end on the fixed-frame-side transverse guide part 15 and with the other axial end on the leaf-side transverse guide part 14. For this purpose, the leaf-side transverse guide part 14 has a spring support 23 which is mounted by means of fastening screws 24 to a base body 25 of the leaf-side transverse guide part 14.

[0036] The lift-off drive 12 of the fitting assembly 4 serves to generate the lifting-off movement of the leaf 3 relative to the fixed frame 2 in the lifting-off direction 8.

[0037] Details of the lift-off drive 12 can be found in FIGS. 3 and 4 for the functional state of the fitting assembly 4 illustrated in FIG. 1 and in FIGS. 7 and 8 for the functional state of the fitting assembly 4 shown in FIG. 5.

[0038] The lift-off drive 12 comprises a drive rod 26 as a leaf-side drive element, which drive rod 26, as shown in FIGS. 1 and 5, is accommodated in the usual way in a fitting groove 27. The fitting groove 27 extends on the leaf 3 in the circumferential direction of the rebate. As usual, the drive rod 26 is covered by a faceplate 28 screwed to the leaf 3. The faceplate 28 is screwed to the frame member 6 of the leaf frame 7. The drive rod 26 can be displaced relative to the faceplate 28 by conventional actuation of the handle (not shown) of the fitting assembly 4 with a lift-off drive movement. A direction 29 of the lift-off drive movement of the drive rod 26 directed into the drawing planes of FIGS. 1 and 5 is illustrated in FIGS. 1 and 5.

[0039] When moving in the direction 29 of the lift-off drive movement, the drive rod 26 is guided on the faceplate 28. For this purpose, a shaft 30 riveted to the drive rod 26 of a control pin 31 attached to the drive rod 26 passes through a slot in the faceplate 28 extending in the direction 29 of the lift-off drive movement (FIG. 5). The control pin 31, which is radially extended relative to the shaft 30, covers the longitudinal edges of the guide slot provided on the faceplate 28 for the shaft 30 and the drive rod 26.

[0040] The control pin 31 forms a leaf-side control element of a leaf lift-off controller 32 of the lift-off drive 12. The control pin 31 is mounted on the leaf 3 perpendicular to the frame main plane 9 via the shaft 30 and the faceplate 28. The fitting groove 27 therefore forms a leaf-side guide groove for the drive rod 26, while the groove walls 33 are provided as guide groove walls.

[0041] The control pin 31 provided as the leaf-side control element of the leaf lift-off controller 32 is associated with a control link 34 provided on the fixed-frame-side transverse guide part 15 as the guide-part-side control element.

[0042] The control link 34 extends on the fixed frame-side transverse guide part 15 in a longitudinal direction along the frame main plane 9 and has a link opening with link walls 35 which are spaced apart from one another perpendicular to the frame main plane 9. When the fitting assembly 4 is mounted on the leaf 3, the control pin 31 of the leaf-side drive rod 26 penetrates parallel to the frame main plane 9 into the guide opening of the control link 34 on the fixed-frame-side transverse guide part 15. The control link 34 extends in the direction 29 of the lift-off drive movement of the drive rod 26 and of the control pin 31 with increasing distance from the frame main plane 9.

[0043] FIG. 4 shows the position of the control pin 31 in the control link 34 in the functional state of the fitting assembly 4 illustrated in FIG. 1. The leaf 3 is located opposite the fixed frame 2 in the position close to the fixed frame. The helical spring 21 provided between the leaf-side transverse guide part 14 and the fixed-frame-side transverse guide part 15 is relaxed. The control pin 31 is located in the control link 34 at the upper end of the link opening in FIG. 4.

[0044] If, based on these conditions, the drive rod 26 is displaced relative to the leaf 3 in the direction 29 of the lift-off drive movement by actuation of the handle of the fitting assembly 4, the leaf 3 will be unlocked from the fixed frame in the usual way. At the same time, the control pin 31 moves inside the control link 34 as a link follower from the position according to FIG. 4 to the position according to FIG. 8. The control pin 31 drives the leaf 3 in the opening direction 8 via the drive rod 26 supported on the leaf 3 perpendicular to the frame main plane 9. The leaf 3 and the leaf-side transverse guide part 14 screwed to it move relative to the fixed-frame-side transverse guide part 15 until the leaf 3 has reached its position away from the fixed frame shown in FIG. 5. In the position away from the fixed frame, the leaf 3 is free from the fixed frame 2. As a result, the leaf 3 can be displaced relative to the fixed frame 2 along the fixed-frame-side guide rail 19 in the shifting direction 10.

[0045] Due to the movement of the leaf 3 and of the leaf-side transverse guide part 14 screwed to it, that is caused by the drive rod 26 and the leaf lift-off controller 32, relative to the fixed frame-side transverse guide part 15 which is stationary during the movement of the leaf 3 and of the leaf-side transverse guide part 14 in the lifting-off direction 8, the helical spring 21 is compressed between the leaf-side transverse guide part 14 and the fixed-frame-side transverse guide part 15. The helical spring 21 is shown in FIG. 6 in the compressed and thus pre-tensioned state.

[0046] As a result of the pretension of the helical spring 21, the control pin 31 is pressed against the link wall of the control link 34 in the direction of action (dashed arrow in FIG. 8) of the compressed helical spring 21. Due to the course of the part of the link wall 35 acted upon by the control pin 31 under the action of the compressed helical spring 21, a play-free mounting of the control pin 31 on the transverse guide part 15 on the fixed-frame side, both perpendicular and parallel to the frame main plane 9, results.

[0047] The play-free mounting of the control pin 31 on the fixed-frame-side transverse guide part 15 and the play-free mounting of the control pin 31 on the leaf 3 result, in combination, in at most a slight play of the leaf 3 perpendicular to the frame main plane 9 when the leaf 3, which is lifted off into the position away from the fixed frame, is moved in the shifting direction 10 along the fixed-frame-side guide rail 19. In addition, play along the frame main plane 9 and rotational play are prevented between the leaf-side transverse guide part 14 coupled to the control pin 31 via the leaf 3 and the fixed-frame-side transverse guide part 15.

[0048] A transverse guide 111 of the fitting assembly 4 shown in FIGS. 9 and 10 differs from the transverse guide 11 according to FIGS. 1 to 8 only in that, instead of the helical spring 21, a leaf spring 121 is provided as a spring element between the leaf-side transverse guide part 14 and the fixed-frame-side transverse guide part 15. The leaf spring 121 is screwed to the base body 25 of the leaf-side transverse guide part 14 by means of fastening screws 123. The fastening screws 123 therefore form a spring support of the modified leaf-side transverse guide part 14.
