Abstract

In order to support a window sash on a fixed frame in such a way that it can pivot around a vertical axis, a horizontal support arm is provided which is connected with a frame-side pivot bearing by means of a support angle, the vertical leg of which grips behind a support plate. An adjusting device which acts in the horizontal direction to change the distance between the sash and the axis of the pivot bearing is not placed in the region of the support angle, but rather at the end of the support arm which is away from the pivot bearing, and acts between the support arm and a filler piece which is fastened in the groove channel of the sash.

Description

The invention relates to a fitting for pivoting a with a rebate surface groove for window or door sash according to the preamble of claim 1.

Modern windows are usually with a tilt and turn sash equipped with a vertical one on the frame Axis rotatable and tiltable about a horizontal axis is. The fitting for the tilt and turn bearing of such Wing consists of a corner bearing in the lower corner and a stay scissors with a stay arm on the upper corner. In addition to tilt-and-turn sashes, there are rotary sashes that Frame only rotatable about a vertical axis are. The hardware for pivoting a wing is traditional completely different from a turn-tilt fitting designed and usually consists of two, at very high Windows also three hinge straps. This means that fittings a different one for turn and tilt sash and for turn sash Have looks and are different from each Hardware components to be manufactured and kept in stock consist.

As part of the modernization and standardization of window fittings it is desirable to design turn-tilt fittings and pivot fittings to match each other as much as possible. On the one hand, such fittings should be as possible have a uniform appearance, e.g. at a double-leaf window with a turn and tilt sash and one Turn the hardware parts visible on the window as far as possible have a uniform and symmetrical appearance. To the others would like to have as many parts of the fitting as possible to be trained so that they can be used for both turn and tilt fittings can also be used for turn fittings, so that only a few fittings when choosing between Tilt-and-turn fitting or swivel fitting can be replaced have to be manufactured separately and kept in stock Need to become. Another point of view relates insist that turn-tilt fittings are normally fitted with an adjustment device are provided to the location of the wing in to adjust perpendicular direction relative to the frame. This adjustment takes place at the lower corner bearing the upper stay scissors due to the bearing play, which in the pivot pin connecting them to the wing is present is, can follow this adjustment. With with hinges stored swing blades is such a horizontal adjustability traditionally not available.

From FR-A-2 275 626 a turn-tilt fitting is known, the extension arm pivotally connected to the wing by a Locking part can be actuated by push rod for swivel operation lockable and detachable from the sash for tilting operation is. Between an attachable in the groove of the wing Filler piece and one for storing the extension arm An adjustment device is effective for the bearing rail.

From EP-A-0 674 075 a rotary fitting is known, the most Swivel bearing arm with a pivot in the Folding groove of the wing fastened filler by a snap connection can be attached. Between the filler and a bearing bracket slidably guided on the filler there is an adjustment device for the end of the support arm effective.

In the unpublished German utility model application 297 07 358.3 describes a fitting for rotating sashes, where the rotating wing is like a rotating and tilting wing with a lower corner bearing and an upper support arm is mounted, the support arm in contrast to the extension arm of a turn and tilt wing with the wing with respect to the vertical axis of rotation is rotatably connected. The support arm is sufficiently flexible in the vertical direction trained to be carried out vertically on the lower corner bearing To be able to follow adjustment movements. 15 to 18 of this utility model application disclose an embodiment, the features of the preamble of claim 1 has and inserted into the groove surface groove of the wing Filler with which the support arm is connected is that it limits in the vertical direction relative to the filler remains movable, but opposite perpendicular to the wing plane acting horizontal forces on the filler is supported or guided.

The invention aims to simplify the design such a fitting while maintaining all of its Features from. The simplification refers to following problem: The in the aforementioned utility model application have described pivot fittings with support arm, after the model of the usual turn-tilt fittings with extension arm, a horizontally acting one in the area of this support arm Adjustment device with which the distance between the wing and the vertical axis of the pivot bearing within a setting range can be set. This adjustment device is, along the lines of numerous corresponding ones Adjustment devices for extension arms of turn-tilt fittings, designed so that the support arm on the horizontal Leg of the connecting him with the bearing plate Bearing angle is guided horizontally and that between the vertical leg of the bearing bracket and the Bracket an adjusting screw is effective. The adjustment device is thus on the one facing the pivot bearing Provided end of the support arm and acts between this and the bearing angle in an area where for housing such an adjustment device relatively little space is available.

The task, in particular, a fitting of the specified type with regard to the design of the horizontal adjustment device to simplify and improve solved according to the invention by the features of claim 1.

The sub-claims relate to further advantageous Features of the invention.

According to the support arm is in one piece with the bearing bracket trained, i.e. the vertical leg of the bearing bracket simply consists of a corresponding bend of the support arm itself. The adjustment device for the horizontal adjustment is at a distance from the swivel bearing Place of the support arm has been relocated, in particular at the other end, and acts between this and that Filler. This results in cheaper ones for the designer Space and greater freedom of design for the training of the adjustment device.

The fitting shown in Fig. 1 is used to dash-dotted sash 1 in the area of his upper corner on a frame 3 around a vertical Bear axis 5 rotatably. The sash 1 has the horizontal and vertical spar each have a fold surface 7, in which is incorporated a conventional rabbet groove 9, the bottom surface is indicated at 11, and that in a known manner to accommodate drive rod and other parts of a Edge gear can serve. For storing the casement 1 on the frame 3 is a pivot bearing 13, which is a Frame 3 fixed by means of screws 15 Has bearing part 17 with bearing eyes 19, on the means of an axle pin 21 received in the bearing eyes 19 a movable bearing part 23 rotatably supported about the axis 5 is.

The movable bearing part 23 is, as shown in particular in FIG. 7 can be seen, bent in one piece from sheet metal and has one the bearing pin 21 surrounding bearing sleeve 25 and the other End of a right-angled bearing plate 27 which in assembled state parallel to the vertical fold surface 7 of the Casement runs and into the rebate space between them and the corresponding fold surface of the frame engages.

The sash frame 1 is attached to the pivot bearing 13 by means of a support arm 30 bent from flat steel and a filler 50, preferably made of plastic is made by injection molding. Support arm 30 and filler 50 are in side view in Fig. 6 and in plan view shown in Fig. 7.

The support arm 30 is on the pivot bearing 13 facing End angled downwards at right angles to form a vertical leg 31, one with the support arm 30th forms one-piece bearing bracket and the bearing plate 27 of the Reaches under the pivot bearing. The vertical leg 31 lies on the side of the bearing plate facing the pivot bearing 13 27 and is on the bearing plate 27 by a Rivet 29, the corresponding holes in the leg 31 and the bearing plate 27 passes through about a horizontal axis rotatably and captively stored. This rotatable bearing the support arm 30 on the bearing plate 27 is used for conversion the fitting to the right or left hinged. A notched one Tongue 33 of the support arm 30 is at its end against the surface of the bearing plate facing away from the pivot bearing 13 27 so that the upper edge of the bearing plate 27 between the tongue 33 and the vertical leg 31 of the Support arm 30 is held. The top and bottom edges of the Bearing plate 27 are, as can be seen in particular from FIG. 8 at 35, rounded to the emergence of the tongue 33 when To facilitate rotation of the support arm 30 relative to the bearing plate 27.

Around the support arm 30 relative to the support plate 27 in the respective the turning position corresponding to the right or left stop to lock, is also by means of the rivet 29 Leaf spring 37 mounted on the back of the vertical Leg 31 of the support arm 30 rests and the end 39th is bent at right angles and as a locking pin in each other aligned openings 41, 43 of the support arm 30 and Bearing plate 27 engages. The spring 37 can against its spring force bent from the vertical leg 31 of the support arm 30 to remove the locking pin 39 from the opening 43 pull out the bearing plate 27 and thus the support arm 30 to release a rotation relative to the bearing plate 27.

The horizontal leg of the support arm 30 is outside the rebate groove of the casement 1 on its upper rebate surface 7 and has a bend approximately in its longitudinal center 44, so that the end portion 45 of the support arm 30 from the folded surface of the casement 1 has moved away. On his from the swivel bearing 13 end, the support arm 30 has one right angled down leg 47, the is also reduced in width, so that it in the upper groove 9 of the casement can engage.

The support arm 30 is not direct with the casement 1, but connected via the filler 50. The filler 50 is preferably an injection molded part made of plastic and has a horizontal part 51, which in the upper groove of the Casement is used and this essentially completely filled, and a vertical leg 53, the engages in the vertical groove 9 of the casement. The Filler 50 is secured with screws (not shown) in corresponding receiving bores 55 of the filler 50 used and in the bottom of the groove 9 of the casement be screwed in, attached to the casement. The support arm 30 has through holes assigned to the receiving bores 55 57 for inserting the screws and the Screwing.

The top side 59 of the filler 50 (FIG. 6) preferably runs flush with the rebate surface of the casement and goes towards the end distant from the pivot bearing 13 via an inclined surface 61 into an elevated contact surface 63 over which the end portion 45 of the support arm 30 rest can.

The support arm 30 is at its remote from the pivot bearing 13 End connected to the filler 50 by means of a horizontal Connecting and adjusting screw 70. This has a constriction between the screw head 71 and a collar 73 75, which in the perpendicularly angled end part 47 is held in a slot between two arms 77. How 3 shows the two arms 77 to each other bent so that the slot formed between them its end is narrowed. As a result, the screw 70 is on Support arm 30 captively secured and rotatable on it, but axially fixed. The threaded portion 79 the screw 70 engages in a formed in the filler 50 Threaded bore 65, the screw 70 can be a self-tapping Be screw so that the bore 65 as smooth Hole can be drilled and the screw 70 when screwing in the bore 75 the associated internal thread cuts. By means of this screw 70 that is from the pivot bearing 13 distal end of the support arm 30 on the filler 50 in its longitudinal direction, i.e. horizontally parallel to the wing plane, adjustable attached.

On the raised surface 63 of the filler 50 on which the Section 45 of the support arm 30 rests is a centering projection 67 integrally formed in a cut out in the support arm 30 Window 81 engages, essentially without play in the direction perpendicular to the wing plane and with one sufficient for adjustment by means of screw 70 Play in the longitudinal direction of the support arm 30. Furthermore is at the top 59 of the filler 50 close to it vertical leg 53 an upwardly projecting guide projection 69 formed in a guide slot 83 of the support arm 30 engages. As can be seen from FIGS. 4 and 7, this lead can be at its top Edge laterally discharging edges 85 and one in the middle have incised slot 87 so that it is resilient with snap action in the guide slot 83 of the Support arm 30 can be used.

As is apparent from Fig. 1, the right runs from the bend 44 located horizontal part of the support arm 30 in a distance from the filler 50, and this area is due to the in the support arm, especially in the area of the bend 44 existing flexibility relative to the filler 50 vertically limited movement, but through the guide and centering protrusions 69, 67 from the perpendicular interacting to the wing level (drawing level in Fig. 1) Forces supported positively.

This creates a structurally simple fitting created the safe storage of the sash 1 on the pivot bearing 13 with sufficient load capacity all forces acting perpendicular to the pivot axis 5 allows. In the direction parallel to the pivot axis 5 between the bracket 30 and attached to the sash 1 Filler 50 has limited mobility, so that the fitting vertical adjustment movements of the wing 1, those on the lower corner of the casement, the pivot bearing for the sash weight (not shown) can be accommodated. Farther there is a between the support arm 30 and the filler 50 Adjustment possibility in the horizontal direction parallel to the Sash level using the adjusting screw 70 to the distance between the sash 1 and the pivot axis 5 of the To be able to change pivot bearing 13. The adjusting screw 70 is at a point remote from the pivot bearing 13 Support arm 30 arranged, in particular on that of the pivot bearing distal end of the support arm 30, making for the adjustment device more space is available and also better access to the adjustment screw 70 for a Screwing tool is given as this on the pivot bearing 13 facing end of the support arm 30 would be the case.

The pivot bearing 13 can also be used for a turn-tilt fitting be used. In this case, the Bearing plate 27 instead of the vertical leg 35 of the Support arm 30 of the vertical leg of a short bracket rotatably supported by the rivet 29, and on this bracket is preferably adjustable in the horizontal direction, the usual extension arm of a turn-tilt fitting is attached.
