Description

Fitting for window sashes The invention relates to a fitting for optionally tiltable around an upper horizontal axis or around a central horizontal axis Axis pivoting window sashes, which at their upper ends around a horizontal axis are rotatable at the ends of handlebars provided with stop bars. which at its lower end around the central horizontal axis on the stationary Frame; are rotatably mounted, with a holding the sash in the ventilation position Extension support.

With such a known arrangement, it is possible to use a normal Ventilation position. Or the sash around a central horizontal axis to turn into a cleaning position. In the ventilation position mentioned, however, is for Limitation of the tilting of the sash is provided by an opening rod which can be detached must be designed so that the wing in the swing position, especially for Clean to be swiveled around the central axis together with the said handlebars can. Apart from the fact that the hanging and unhooking of the opening frame in the known device when the sash is to be rotated in the cleaning position, is disadvantageous and the hanging linkage interferes with the pivoting of the sash, the said linkage also allows only a single folding position during movement around the upper horizontal axis, which can be changed in its height on the stationary Frame is set.

There are also fittings known in which a folded position of the wing around an upper horizontal axis, in that the wing over a handlebar-like support is hinged to the fixed frame and that when exhibiting in the folded position, the position of its folding axis on the upper edge in terms of height changes.

With these so-called Italian windows it is known that the Slot guide for the folding axis with notches on the top of the sash to provide or to arrange friction brakes in the joints of the fitting to different To achieve ventilation positions of the sash. It is also known to any of the Fittings arranged on both sides of the wing to be combined into one structural unit. In these known constructions, however, it is not possible to use the window sash optionally to pivot about 180 ° around a central axis.

It is also known for an Italian-style window that the window sash after fixing the prop on the fixed frame to pivot the joint connecting the prop with the wing by almost 180 °. To do this, however, it is first necessary to create a vertical joint between the Open the strip covering the sash and the fixed frame to the outside. aside from that the sash cannot move in different directions when opening around the upper horizontal axis Ventilation positions are brought.

The invention is based on the object of a fitting of the initially called genus, which in a simple manner after the type of Italian Windows can be brought into different ventilation positions without swinging of the sash around the central horizontal axis, a prop can be uncoupled got to.

According to the exemplary embodiment according to FIG. 1 to 4, the movable wing 1 is mounted on two articulated links 9 on the fixed frame 2 by means of two pins 3, which are attached to the outer sides of the vertical struts of the wing 1 at the level of the upper cross strut. A fitting 4 with vertical slots 4a, which is arranged on the inside and at the upper end of the link 9, guides the corresponding pin 3. The links 9, which are T-shaped in cross-section, are at their lower ends. each by means of a hinge pin $ on a bearing part 10 fastened to the fixed frame 2 at about mid-height so that it can pivot about a horizontal axis. The slot guide is equipped with a movable locking plate 5 which, in the closed position of the wing, leaves the slot 4 a in the fitting 4 free with the exception of its lower end, where a stop is provided which is taken along by the pin 3 on the wing in the greatest possible tilt position and the movable locking plate 5 adjusted so that notches or notches protruding from the slot 4 a in the Besehlagteil 4 are blocked. The locking plate is returned to its original position when the pin 3 has reached its highest position again. by movable wing 1 is held in the tilted position by two lateral props 6: the one at one end by means of a screw 7 o4. Like, are rotatably mounted on the wing 1 and at the other end on the hinge pin 8 on the fixed frame.

The extension supports are similar to the well-known "Italian" windows designed so that the window sash with the lowest possible effort opened can be and automatically in one of the notches of the slot guide as desired notices. The links 9 are each provided with a sliding bolt 11 at their upper ends equipped, with the help of which they are attached to the upper transverse part of the fixed Frame can be set. When the wing rotates 1.80 ° around the central axis is to be pivoted, the latches 11 are released, and the pivotable handlebars 9 can thus move away from the upper cross strut of the fixed frame. she make here the movement of the movable wing with, whereby they through the engagement the pin 3 in the slots 4 a remain firmly connected to the wing.

Reach for the embodiment shown in FIGS two pins 14 arranged on the window sash 12 in slots provided with notches 4 a on the fixed frame 13. The slot guides are in opposite to the first Embodiment opposite, provided inclined box openings. The slots 4a .are also equipped with an inlet opening 15 in their lower part, through which the pin 14 can leave the slot guide, so that the movable Wing can be released from the fixed frame 13. by wing 12 is of two Handlebars 16 held, which in turn are pivotably mounted on the fixed frame are. The links 16 are at their upper end at the upper end of the wing 12 by means Hinges 17 are hinged, while at their lower end they have further hinges 18 are rotatably mounted on the fixed frame 13. The hinges18 are roughly in the Arranged in the middle of the vertical struts of the fixed frame 13. In contrast to In the first-mentioned embodiment, the pins 14 are below the upper cross strut and fastened at such a distance above the central hinges 18, so that the wing is approximately in equilibrium in larger tilt positions, in order to facilitate handling in this way.

To open the movable wing, all you need is the wing 12 downwards outwards: pushed and the pin 14 in the: the desired inclination corresponding notches in the slots 4 a to be brought into place. if the sash is to be swiveled 180 ° around the central horizontal axis the wing 12 is pulled inwards in its upper half, whereupon it moves into the after F i g. 6 reaches the position shown. In this embodiment there is no actuation A locking device is required when the sash is out of the normal ventilation position according to FIG. 5 in a pivoting position about the central horizontal axis according to F i G. 6 is to be brought. Rather, it is possible to convert the wing into a normal ventilation position or in a cleaning position swiveled by 180 ° bring that either the wing is pushed outward at its lower end or is pulled inwards in its upper half. In this way it becomes an extraordinary one Ease of use achieved.

In the embodiment according to FIG. 8 to 14, the slot guide consists of a straight slot 21, while the pin 22 is designed as a screw which is arranged at the upper end of the upper cross strut 23 of the wing 19. The pin 22, which slides in the vertical direction in the slot 21, is braked during its movement by friction disks. 24 and 25, whereby the brake linings can consist of conventional, suitable material. The braking force is adjusted by. a nut 26 or a corresponding part. The movement of the pins 22 can also be decelerated by springs or other suitable means, specifically on each pin independently of the other. A bolt 30 is provided for locking the sash in the closed position. The upper cross brace 23 of the wing 19 is provided with a bead 32 which, when the wing is closed, engages in a groove 33 arranged in the upper cross brace 31 of the fixed frame. The arrangement of the bead and groove can also be reversed. When the sash is closed, it is thus secured against movement inwards or outwards over its entire width at its upper end. If the wing 19 is to be pivoted about the central axis, it must first be brought into a suitable inclined position, as shown for example in FIG. 11, so that the bead 32 disengages from the groove 33. After the wing is in this position, it is sufficient to pull the wing on the upper cross strut 23 inward. The wing then swivels around the central axis. Each of the fittings arranged on both sides of the sash 19 consists of a coherent structural unit which is arranged in a concealed manner in the window parts and is therefore invisible when the window is closed. Each fitting consists initially of a link 35, which is designed as a U-profile and is pivotably mounted at its lower end via a hinge bracket 37 by means of a hinge pin 34 on a tab 38 attached to the stationary frame 20. In the upper part of the link 35 , the sliding guide is cut out in the form of the slot 21, into which the pin 22 engages and on which the brake direction described above is arranged. The pin 22 is arranged at the end of a bracket 36 which is provided at its other end with a pivot pin 28 on which the deployment support 29 is rotatably mounted. The support consists of a rod or a flat profile and is mounted at its other end on a hinge pin 27 which is arranged on the hinge bracket 37 attached to the lower end of the link 35. The distance between the hinge pin 34 and the upper end of the link 35 corresponds to half the height of the movable wing.

The joint connecting the handlebar 35 to the fixed frame 20 is also equipped with a braking device, which consists of a disk 19 Metal, fiber, nylon or equivalent material. The pivot pin 34 consists of a screw, .the freely through -the hinge bracket 37 and the washer 39 passes and is screwed into the tab 38. A lock nut 40 is used To adjust the braking force, a braking device can also: on the pivot pin 27 and 28 are provided.

To attach the fittings, grooves 41 and 42 are made on the sides of the vertical struts of the wing 19 and the fixed frame 20 in their upper half. The bracket 36 is fastened to the outside of the wing 19 with the aid of screws 43, so that the pin 22 is at the upper end of the bracket. The flap 38 is fastened with the aid of the screws 44 on the inside of the vertically extending frame part in such a way that the hinge pin 34 is approximately in the middle of the height of the wing. The fastening of the two parts mentioned on both sides of the wing is sufficient to hold the wing and to be able to operate it. For complete sealing, a strip 45 is placed on the inside of the link 35 by means of screws 46. This hides the fitting from the outside.

The window according to the present exemplary embodiment can be operated in four different ways: 1. The window can be moved into the position shown in FIG. 11 shown ventilation position are brought; 2. The window can be pivoted about its central axis according to FIG. 12 into any angular position, whereby it maintains the position set in each case due to the friction brakes on the hinge pin 34; 3. the window can be pivoted inwards by 180 °, as shown in FIG. 13, and 4. it can be adjusted via the position according to FIG. 15 are also tilted inwards and an angular position according to FIG. 14 occupy, whereby it is held in the respectively desired position by the braking effect between the pin 22 and: the slot 21. -In which g in the F i. 15 and 16 illustrated embodiment. The fittings arranged on both sides of the wing 50 are also designed as a coherent structural unit and each consist of a link 47 provided with a bar 48, which is articulated at its lower end on the side strut 49 of the fixed frame, and one attached to the wing 50 Tab 51 and a deployment support 52, one end of which is articulated on the tab 51 in the pin 53 and the other end of which is rotatably mounted on a pivot pin 54 at the lower end of the link 47. The pivot pin 54 consists of a screw, between the head of which and the deployment support 52 a plate 56 made of metal, plastic or other workstop is arranged, which is fastened to the side surface of the link 47 by means of a screw 55. The plate 56 serves as a braking member, the braking force being regulated by tightening or loosening the pivot pin 54, which is designed as a screw. If necessary, the same braking device can also be used for other articulated connections. In the embodiment according to FIG. 17 to 20, the movable wing 50 is again arranged on the fixed frame with the aid of two fittings forming a coherent structural unit, but the wing 50 can be tilted about a lower horizontal axis, and the attachment of the. Hardware is reversed compared to the previous examples. The links 61 are now located in the lower half of the window and on the surface that faces outwards and are rotatably connected at their upper end to the side struts 49 of the fixed frame, while at their lower end they are either with the help of bolts 62 , 63 are held on the fixed frame or are released after unlocking. The latches 62, 63 can be attached either to the fixed frame or to the links 61. If both links 61 are fixed with their lower ends on the fixed frame, the wing takes the inwardly inclined ventilation position according to the F i g when opening. 17 and 18 a. If, on the other hand, the two links 61 are released from the fixed frame at their lower ends, the wing can, as shown in FIG. 20 or any intermediate position between that of FIGS. 18 and 19. The positions of the wing according to FIGS. 19 and 20 are advantageous when the outside of the window pane is to be cleaned.
