Abstract

What is provided is a fitting for positively tiltable and parallel-settable wings with wing rebate (10) of windows, doors or the like, in which the wing is held and guided so as to be both tiltable and settable in parallel by means of setting-out arms (8, 9). For positive actuation, an actuating linkage (16) arranged on the wing cooperates with the setting-out arms. For this purpose, an espagnolette element (17) of this linkage is held and guided in the region of the fitting on one side of a bearing plate (18) fixable to the casement, whilst the setting-out arm (8, 9) is mounted non-displaceably on the other side laterally next to the espagnolette element on the bearing plate (18). The setting-out arm has a portion (20) resting flat on the top side of the bearing plate and having a control curve (33, 34) which is open towards the wing rebate (10) and which consists essentially of two straight curve segments (33, 34) which form an angle well above 90 DEG and which cooperate with an actuating stud (25) or the like connected directly to the espagnolette element (17). The setting-out arm (8, 9) is guided out of the wing rebate, without the wing rebate (10) having to be provided with a recess or perforation for this purpose. <IMAGE>

Description

The invention relates to a fitting for, in particular, forcibly tiltable and parallel lockable and lockable sashes in the closed or shutdown position with sash overlap of windows, doors or the like with the features of the preamble of claim 1 and claim 2.

Such sliding sashes and associated fittings are known in various embodiments. As a rule, the wing is supported on its upper edge and its lower edge by two extension arms, which are articulated on the one hand on the wing and on the other hand are articulated to running members which are arranged on the inside of the frame. The arrangement is such that at least the upper extension arms can be forcibly pivoted in the opening and closing direction via the actuating linkage arranged in a conventional profile groove of the wing in the area of the fold (cf. DE-OS'n 30 50 975, 26 48 344, 26 33 369, 27 00 598, 40 16 341 or EU-OS 021080).

It is known to pivot these outrigger arms on a cover rail which covers the porile groove of the wing lying in the area of the wing rebate and serving to receive elements of the actuating linkage (cf. DE-PS 30 50 971). In this known embodiment, the extension arm is designed such that it runs without an opening or recesses in the area of the wing flap from its end lying in the sash rebate to the end extending to the guide rail or the like attached to the inside of the frame.

In other designs of this type (cf. DE-PS 26 48 344), the deployment arm articulated in the area of the wing profile groove on the cover rail or a corresponding cover element is guided outwards through an opening or recess in the wing flap. The extension arm has a right-angled control cam, which is open to the outside and lies outside the profile groove of the wing. A control cam is connected with the aid of a bracket to the ends of the actuating linkage on both sides of the fitting such that the control cam arranged on the bracket can be moved longitudinally displaceably with the actuating rod. In another embodiment (cf. DE-Ps 26 33 369) the extension arm is by means of a Fastening plate attached to the wing profile laterally next to the profile groove and has a closed rosette-like cam in the area above the profile groove, in which a control pin directly connected to the actuating rod engages (cf. also DE-OS 27 00 598).

The latter two embodiments are only intended and suitable for sliding doors that can be set in parallel. For additional actuation, e.g. for tilting the wing, the length of the cam sections is not sufficient. The latter two designs also require special, deeply engaging bearing bushes for receiving corresponding pivot pins with which the extension arms are pivotally mounted in the hollow profiles in order to be able to safely transmit the sash weight to the frame, which consists of hollow profiles.

To avoid these disadvantages, it is known to provide extension arms with an additional control arm for tiltable and parallel adjustable and displaceable wings (cf. DE-PS 40 16 341). However, if a separate mounting plate for the extension arm is necessary, as is the case with the fitting according to DE-PS 26 33 369, the height of the sash rebate is no longer sufficient to accommodate an additional control arm.

However, it is also known to guide and hold the upper edge of the wing through a single extension arm (cf. DE-OS 28 39 797). In this known fitting, the extension arm reaches through a wide opening into the interior of the frame profile and is pivotally mounted there. The guide rail is arranged on the upper edge of the casement. In relation to the sliding direction used for opening, the fitting engages in the area of the upper front wing corner on the wing. This arrangement requires extensive processing, a special profile for the frame and harbors the risk of warping the casement.

The sash in the fitting according to EU-OS 021 080 remains in its level corresponding to the closed position for shifting. The adjacent fixed window or door field must therefore be offset according to the depth so that the movable wing can pass through this window or door field accordingly. With the known fitting, the extension arm thus has nothing functionally with the displaceability of the Wing to do. It is therefore not shown when the wing sliding movement, but - to relieve the sealing element - only slightly depressed, corresponding to the weak inclination of the slot section with respect to the longitudinal course of the extension arm. The extension arm thus essentially serves only to be able to pivot or tilt the sash from the closed position into a tilting position or ventilation position about the lower horizontal axis. If one considers the switching path of the actuating linkage, the switching path controlling the ventilation position is due to the end of the entire switching path facing away from the locking position of the linkage and thus to the end of the entire switching path facing away from the closed position of the wing. The known fitting is unsuitable for the purposes here.

It is an object of the invention to develop a fitting for forcibly tiltable and parallel lockable and lockable sash with sash overlap of windows, doors or the like. With the features of the preamble of claim 1 so that despite the several, controllable open positions of the Wing an additional control arm is not required that the fitting is also suitable for larger sash weights and can be easily and simply installed without major changes in the profile of the sash frame and connected to conventional locking or actuating linkages.

This object is achieved by the teaching of claim 1.

According to this solution, the raising arms supporting the wing are each made in one piece, ie without an additional control arm or the like. They are preferably provided for the upper edge of the wing, but can also be used to support the wing on its lower edge. The forces to be absorbed are reliably absorbed by the usual mounting or bearing plate that serves to accommodate the linkage, which can be attached directly to the profile and on which both the drive rod element can be held and guided and the extension arm is directly supported without it further storage means built into the profile of the wing are required. The actuating linkage acts via the control cam or the like which is attached directly to the drive rod element and which engages through a slot in the bearing plate, with a control curve which is open towards the flap of the wing together. This can therefore have comparatively long control cam sections for the closing and opening of the wing, which remain in any position of the wing in the region of the width of the bearing plate, so that recesses or openings on the flap of the wing do not have to be incorporated for this or for the removal of the raising arm.

The control curve, which is open to the side, preferably has straight curve sections of great length, which enclose an angle well above 90 ° with one another.

The new fitting enables all parts of the fitting to remain behind the flap, despite the relatively long pushing distances required to control the various positions of the linkage and the sash, so that this does not require any processing.

To bring the cranked extension arm out of the area of the sash rebate, it is necessary to interrupt the seal provided on the sash flap in a corresponding area.

This can advantageously be avoided if the section of the extension arm articulated on the bearing plate is led out of the fold area together with the bearing plate through a relatively narrow slot in the rollover and the extension arm is cranked only outside the rollover.

This does require machining of the casement. However, the intervention is only slight, since it does not require a profile cutout, such as for the pivoting of the opening arm of DE-OS 26 48 344 mentioned above. In addition, the narrow slot in light metal or plastic profiles can be produced with the punching tool that is available anyway, which is required for the arrangement of the usual gear handles.

The leading out of the bearing plate and extension arm through the narrow slot leads to the pivot point of the extension arm coming to lie in front of the plane of the casement and so the control cam has a particularly large force effect on the extension arm via a particularly large lever arm can. The slot and / or the extension arm and the bearing plate can be visually covered by a cover profile if necessary.

For the large length of the control curves, the undercut of the wing flap is also advantageously used in the usual hollow profiles of the wing.

A solution to the problem for a fitting according to the preamble of claim 2 provides the teaching according to claim 2 with only a single extension arm. The advantages stated for the teaching according to claim 1 apply accordingly to this teaching.

The fitting according to the teaching of claim 2 makes it possible to arrange all parts of the fitting, including the raising arm and guide rail, completely concealed in the sash rebate and to avoid perforations or processing as well as special profiles for sash or frame profiles. It is also achieved that the extending arm articulated to the sash frame engages substantially more towards the center of the sash and can reliably support it without the risk of twisting. The extension arm does not need to be cranked either. The extension arm need not be positively controlled. But the new training offers the advantage of the possibility of forced control over the prior art mentioned at the beginning. An additional control arm or the like is not required. Nevertheless, all three above-mentioned positions of the extension arm can be controlled via the actuating linkage, ensuring that the sash is reliably locked in each of these positions.

The invention is explained in more detail below with the aid of schematic drawings using several exemplary embodiments.

In Figures 1 to 13, the frame is designated 1 and the profiled hollow frame for the wing with 2. In Figure 1, the circumferential in the area of the sash rebate, largely standardized profile groove 15 is indicated, in which rod elements or the like. A conventional actuating linkage are arranged, which is indicated in Figures 1 to 3 by its actuating lever. With the help of this actuating linkage, upper and lower extension arms 8 and 9 of fittings which are the subject of this description can be actuated.

The free ends of the upper extension arm 8 have running members 23 which engage in a running rail 4 mounted on the inside of the frame 1. The free ends of the lower extension arms 9 are articulated on running members, as indicated in FIG. 1, which are car-like or sledge-like and can be moved parallel to the plane of the frame on a running rail 6 provided on the frame 1.

Figures 4 and 5 show, on an enlarged scale, sections through the upper region of the frame and casement. The section according to FIG. 5 shows the design in the area outside the fittings 5, while FIG. 4 shows the section in the area of the fitting 5.

The fittings 5 for the upper wing edge are shown and described in more detail below. However, it is expressly pointed out that the basic features of the fittings which are of interest here can also be provided for the fittings for the lower wing edge.

FIGS. 4 and 6 show the section of the wing profile which has the usual and mostly standardized fitting groove 15 for the actuating linkage. The width of this profile section is indicated by 43 in FIG. 5, the width being measured from the inner surface of the wing flap 10. In areas outside the fitting are in the Profile groove 15, the actuators 16 of the actuating linkage stored and guided. The hardware groove can be undercut for this purpose. In this area, the hardware groove can also be covered on the outside by a cover rail.

In the area of each fitting 5, a special linkage element 17 is provided, which, as shown in FIGS. 6 and 7, can be easily and quickly coupled to the subsequent linkage members 16 via simple coupling pins 30 and corresponding bores. The rod element 17 is held directly on the underside of a mounting or bearing plate 18 and is guided in a longitudinally displaceable manner. The bearing plate 18 engages over the fitting groove 15 and, according to its width 41, takes up practically the entire free width of the section of the casement profile which has the fitting groove 15, as can be seen in particular from FIG. 4, but also from FIGS. 6 and 7. Laterally next to the fitting groove 15, a flat lying section 20 of the extension arm 8 is pivotably mounted on the upper side of the bearing plate 18 with the help of the bearing pin 24. The section 20 of the extension arm 8 has a width 42 which does not exceed the width 41 of the bearing plate 18.

The bearing plate 18 has a longitudinal slot 31 in the center above the fitting groove 15, through which an actuating pin 25 engages, which is connected directly and firmly to the rod element 17. The section 20 of the extension arm 8 has in the area of the slot 31 a control curve 32 which is open towards the flap 10 of the wing. In the exemplary embodiment shown, this consists of three curve sections 33, 34 and 35. The two outer curve sections 33 and 34 are essentially rectilinear and form an angle of approximately 135 ° with one another. The angle should be significantly greater than 90 ° and can be between 95 ° and 150 °, but preferably between 120 ° and 140 °. In the two pivot positions of the extension arm 8, which are limited by a stop 40 fastened to the bearing plate 18, one of the straight control curve sections 33, 34 lies parallel and preferably in alignment with the limiting edge of the longitudinal slot 31 remote from the flap 10 of the wing. The middle curve section is circular and so arranged that in each case the transition to the adjacent rectilinear section 33 or 34 in one of the end positions of the extension arm 8 is approximately in the middle above the longitudinal slot 31, as is readily apparent from FIGS. 6 and 7.

Due to this design, the straight curve sections receive an effective length 45, which is particularly large and is sufficient for the control of the different positions: closed position, tilt position, parallel position and ensures that the extension arm 8 in each of these positions by interaction of the curve sections with the Control pin 25 is locked so that the wing can not be moved by external forces.

When the invention is applied to the lower extension arms, the lower end of the wing can be pulled off or released from the frame with the aid of the actuating rod.

It can be seen that the extension arm 8 has an outer section 22 which is connected in an articulated manner to the running member 23 and which is connected to the section 20 resting on the bearing plate 18 by an angled section 21 lying behind the wing flap 10 in the closed position of the wing . This design allows the extension arms to be attached without having to make 10 recesses or openings in the flap.

FIGS. 6 and 7 also show that, despite the great length of the individual curve sections of the extension arm, the entire control curve remains within the width 41 of the bearing plate 18 in every position of the wing. In this respect, too, it is not necessary to process the wing flap during assembly.

The actuating section 17 can be held and guided on the bearing plate 18 with the aid of the fastening element 19 used to fasten the bearing plate to the profile. For this purpose, the rod section 17 has corresponding longitudinal slots.

In the embodiment shown in FIGS. 8 to 10, the control cam 55 of the extension arm 51, which is open to the side, points away from the inner surface 64 of the wing flap 63 of the wing 40. The extension arm is mounted with a section 52 resting on the upper side of the bearing plate 45 in the immediate vicinity of the wing overlap 63 between the latter and the vertical longitudinal center plane 41 of the profile groove 42 and the actuating linkage 43.

The bearing plate 45 is fastened to the profile of the wing 40 by means of screw 46 on the bottom of the profile groove 42. A drive rod element 44 is held and displaceably guided on the underside of the bearing plate 45 and forms a preassembled structural unit with the other parts provided on the bearing plate.

The control curve 55 in turn has two straight curve sections 56 and 57, the length 62 of the section 56 being substantially greater than the effective length 61 of the section 57. A curved control curve section 58 is provided between them. On the side of the bearing plate 45 opposite the pivot point 53 of the raising arm 51, a limit stop 50 is provided, which interacts with the control curve sections 56, 57 in the manner already described.

As can be seen in particular from FIG. 10, the longitudinal slot 60 in the bearing plate 45 is offset relative to the vertical longitudinal center plane 41 of the profile groove 42 to the side facing away from the wing flap 63. The control cam 49 is connected to the drive rod element 44 via a cranked element 48 in such a way that the control cam 49 is clearly offset in the same direction as the longitudinal slot 60 with respect to the vertical longitudinal center plane 41 of the profile groove 42. It is designed like a head and is supported on the top of the bearing plate 45 on one edge region of the longitudinal slot 60.

It can be seen from FIG. 8 that in the closed position of the wing the contact point between control cam 49 and cam 55 lies in a region which lies between the articulation points provided at the ends of the raising arm 51, of which only the articulation point 53 is shown on the bearing plate 45 .

The extension arm 51 is in turn cranked parallel to the flap 63, so that in this embodiment too the flap flap 63 can be designed practically without recesses or openings.

In this embodiment, since the effective length of the curve section 57 is less than the effective length of the other straight curve section 56, the bearing plate 45 can be somewhat narrower than the overall width if required of the section of the casement profile having the profile groove 42. However, this is not critical since there is sufficient space for a longer cam section 57 in the direction away from the wing flap (cf. FIG. 10).

The described relative position of the control cam in the closed position (FIG. 8) of the opening arm leads to a significantly improved and more resilient locking of the opening arm in the closed position of the leaf.

The embodiment according to FIGS. 11 and 12 differs from that according to FIGS. 8 to 10 primarily in that the wing 70 has a narrow slot 78 in its flap 71 through which the bearing plate 74 and the section 76 of the extension arm 75 articulated thereon reach out of the profile area in front of the plane of the wing 70. There, with the formation of a large force arm of length 84, the articulation point 77 is located, as is the cranking of the extension arm 75.

In this embodiment, the control cam 81 and the longitudinal slot 80 can be arranged centrally to the groove 72 and the actuating rod 73. For the control cam with its sections interacting on a stop 82, the same applies to the exemplary embodiment according to FIGS. 8 to 10.

It can be seen that the seal provided on the flap need not be broken. It can also be seen that the slot 78 is only very narrow and can easily be punched out with a tool which is anyway required for other purposes.

Slot 78 and / or bearing plate 74 and extension arm 75 can be visually covered by a profile 95.

FIG. 13 shows, in a representation corresponding to FIG. 11, the application of the fitting in the lower region of the wing 70. The extension arm 93 articulated on the bearing plate 92 can therefore be articulated on a lower carriage or carriage 91 which is guided on the bend frame 90.

11 to 13 results in addition to the advantages of avoiding an interruption of the window seal at the flap and the even better power transmission, the advantage that the stay arm with its crank outside in front of the wing with the bearing plate 74 as a pre-assembled unit from the outside through the slot in the wing flap and can be coupled with the control cam.

In the embodiment of the invention according to FIGS. 14 to 16, lower fittings are denoted by 105, a groove receiving the actuating linkage by 103 and the associated handle by 104. In the area of the upper fitting 106, a drive rod element 112 is arranged in the profile groove 103 of the casement 102, which is connected at its ends 112a to the ends of the adjacent parts 111 of the usual actuating linkage by a releasable hole / pin coupling. In the area of the fitting, the profile groove 103 is covered by a bearing plate 114 which can be screwed onto the sash profile. The bearing plate has a longitudinal slot 122 through which a control cam 125, 125a or the like which is cranked laterally relative to the vertical central plane 135 of the profile groove 103 extends. The head-like cam 125 rests on one side on the edge area of the bearing plate 14 delimiting the slot 122.

In the area between the profile groove 103 and the flap 110 of the wing, an extension arm 115 is pivotally mounted on the bearing plate 114. This is made possible by the fact that the bearing plate in the undercut of the wing flap extends to the inside surface thereof. The extension arm 115 is formed in one piece and in one piece and has a section 115b resting on the bearing plate 114 and a section 115a which is slightly bent upwards relative to the latter. This section is pivotally connected at 116 to a running member 131 which engages in a guide rail 130 which extends over the upper edge of the wing in the wing rebate along the frame 101. The guide rail 130 could also be formed by an undercut profile provided on the frame itself.

In its region 115b, the deployment arm has a control curve which is open towards the side facing away from the wing flap 110 and which has two rectilinear curve sections 119 and 121 which are connected to one another by a profiled or curved curve section 120. The curve sections 119 and 121 form an angle of approximately 120 ° to 140 °.

The curve section 119 is significantly longer than the curve section 121. Both curve sections have a comparatively large effective relative length and thus allow long thrust distances for the actuating linkage to control the various positions of the wing.

The arrangement is such that, in the closed position, the contact between the control cam 118 and the control cam 125 lies in the area between the two articulated ends 116 and 117 of the extension arm. This results in a particularly effective locking of the leaf in the closed position. But also in the other positions of the wing this is locked by the interaction of the cam and the control cam.

The bearing plate 114 can be made strong and wide and lie on the profile of the casement over a large area, so that it can also reliably transmit large forces. The forced control takes place reliably even without an additional control arm and without overstressing the hardware components. The drive rod element 112 can be held and guided on the underside of the bearing plate 114 and thus form a preassembled structural unit with the latter and the extension arm. Installation is therefore extremely simple, especially since changes to the frame profiles do not need to be made. The fitting can therefore be easily accommodated on the sash rebates of the usual dimensions. A cover rail for the profile groove 103 is unnecessary.

The extension arm does not necessarily have to be positively controlled in order to bring out the advantages mentioned at the outset. Rather, it can also be part of a simple folding scissors hinged to the upper edge of the wing. In this case, the arrangement is made accordingly so that in the closed or tilted position of the wing the running member is located in the area of the rear frame corner seen in the sliding direction.
