The control arm at least in the area of the control curve preferably has an L, U or C shaped cross-section perpendicular to arm length direction.

Description

BACKGROUND OF THE INVENTION The invention relates to a swivel fitting for windows, doors or the like, comprising an exhibitable scissor unit, with a control arm on a wing movably mounted and a plug member cooperating with a control curve on the underside of the control arm inclined to the wing. for pivotal opening of the sash, the control arm is a plug member attachable to the sash in a parallel position, and for tilting the sash, the control arm can be released from the plug member to move the control arm in a first direction to the tilt position.

BACKGROUND OF THE INVENTION Rotary tilt fittings of this kind are known. Vystavovací k

the scissor unit has at least one, often more than k

the arm, the exposing arm, connects the wing to the fixed frame, one end of which is movably on the wing

^Ř - ^ø : 1 25 bearing and its other end carries part of the pivot bearing of the top ·?

. pivot bearing of window, door or the like. In order to limit the possible tilting opening angle, the exhibiting scissor unit usually has an additional arm, a connecting guide component, which is controllable to the wing as well as to the exhibiting arm. In order to rotate the opening of the wings

In the parallel position of the exposing arm in the parallel position, this or the connecting guide member is provided with a control curve which interacts appropriately with the plug member. The plug member and the control arm must be located within a relatively limited installation space between the sash and the fixed frame. In the known swivel fitting, this installation space is further reduced by the fact that the control curve is formed by a part with a special C-shaped profile on the underside of the display frame with a central C-shaped profile arm positioned on the display arm. Correspondingly, the thickness of the center arm increases the requirements for vertical installation space. To ensure reliable interaction between ^one bolt member control cam are therefore permissible only slight zhotovovací and assembly tolerances with respect to the relative vertical position of the plug member and the control curve. Problems with the height of the installation space (= vertical clearance of the groove) available may also occur in the region of a possible longitudinal arm adjustment device.

The basis of the invention lies in the technical problem of preparing a swivel fitting with reduced requirements for vertical installation space.

SUMMARY OF THE INVENTION

To solve this problem, it is proposed that the control arm, at least in the region of the control curve and / or in the area of the longitudinal adjustment device of the arm, have an arm bent towards the wing on its

-3 with respect to the first direction of the front longitudinal edge.

A bent arm of the control arm leads to a substantial increase in the mechanical strength, in particular the flexural strength of the control arm

In this region, so that the thickness of its material can be

Γ | correspondingly reduced. The thickness of the part forming the underside of the control arm with the control curve, which extends in a plane containing the first direction and which co-determines the vertical construction height, decreases accordingly. Output resp. the entry of the control member into the control curve region below the actuating arm when the wing tilting opening or closing is not restricted by the bent arm, as this is directed at a given leading edge of the control arm. According to the invention, the vertical installation space of a possible longitudinal arm adjusting device is reduced in the same way.

Preferably, the control arm is assumed to have an L-shaped or U-shaped or C-shaped shape at least in the region of the control curve at a cross-section perpendicular to the direction along the arm. In the case of a U or C shape, the arm is correspondingly saved for the outlet or inlet. In order to obtain the specified cross-sectional shape, the control arm resp. the corresponding section of the control arm is correspondingly profiled, in particular by bending the metal sheet, which fulfills the condition of cost-effective manufacture of the swivel fitting essential in mass production. In special fittings, the control arm may also be formed by a corresponding shaped part, in particular a pressure-cast part.

The control curve may also be formed by the lateral edges of the control arm, as the case may be, if this has a C-shaped cross-section. A portion of the control curve can also be formed by a shaped part, so that complicated shapes can also be achieved without further. The portion of the control curve on the actuator arm may also be configured to be adjustable substantially parallel to the first direction, so that the position of the control curve can optionally be adjusted relative to the plug member to ensure reliable interaction of the control curve and the plug member. Alternatively, the sash pressure can be optionally adjusted during installation or after prolonged use.

A compact, mechanically stable shape of the structure is obtained when a portion of the control curve closes substantially in relation to the free edge of the bent arm and / or when a portion of the control curve closes substantially in relation to the edge of the exposure arm remote from the bent arm.

It is particularly preferred that part of the control curve is substantially L or U-shaped with the free ends of the arm resting on the control arm. Thus, no arm abuts the underside of the display arm. Thus, the plug member can utilize the entire space below the display arm to the bottom. The requirements for the vertical installation space of the exposure scissor unit are therefore correspondingly small

-5resp. the manufacturing and mounting tolerances for the relative position of the wing member and the actuating arm can be selected correspondingly large. Thus, the swivel fitting can be used ₍ 5) for different window profile shapes and for different vertical groove clearance.

In order to be able to realize, by means of structurally simple means, the aforementioned advantageously adjustable adjustment of the control curve portion on the actuating arm independently of a predetermined angle shape of the actuating arm, it is proposed to rotatably mount the control curve portion on the actuating arm, optionally adjustable in different rotational positions extending into the toothing of a portion of the control curve for an adjustment direction substantially parallel to the spindle axis. To selectively vary the effective length of the sash adjusting arm or the adjusting arm. to adjust the sash after prolonged use, a corresponding adjusting device on the exposure arm is provided. This may include an adjusting screw that is movably mounted in a sheet holding the adjusting spindle on the underside of the display arm, preferably of a compact construction form.

To this end, the adjusting screw can be assumed by a portion (25 of the external thread) to engage the internal thread of the adjusting portion carrying the rotary joint part of the rotary joint and the adjusting portion is slidably mounted on the display arm in the direction of the longitudinal arm.

In order to ensure the slightest vertical requirements again

It is proposed that the adjusting portion have a leading protrusion that extends into the leading slot of the exposure arm.

AND

Various embodiments known per se are possible for the male member. However, it is particularly preferred that the plug member is formed by a mushroom-shaped head. This achieves a reliable coherence of the plug member and part of the control curve; a downward rotation of the plug member from the control curve portion is excluded.

Due to the increased permissible vertical tolerance between the plug member and the actuator arm according to the invention, the plug member can also be formed in another simpler embodiment, a substantially circular cylindrical pin. The invention further relates to a window, door or the like with a swivel fitting of the type described above.

The invention will be further elucidated on selected examples of embodiments in the figures.

i. Examples of the invention. The figures show the exposure scissor unit 1Ό; <. together with the upper rail 12 as part of a swivel fitting not further illustrated. The upper rail 12 is formed by a connecting rod section 14, from which a portion on the side of the pivot bearing (right end in FIG.) Is subsequently shown. The other end &apos; is connected to the force transmitting member upstream of the pivot axis * of the distal corner rotation element.

I i

The top rail 12 further comprises a section of the cuff rails

16, which reveals the connecting rod section 14 from above and in FIG.

? The distal end not shown of the rotary bearing is connected to a corner angle of the upper rotary bearing of the distal corner rotation element.

The display scissor unit 10 is shown in the demonstration

For example, the display arm 18 is movably mounted on a section of the cuff rails 16 with its left-hand end on the sides of the wing in the direction along the rails. For this purpose, the actuating arm 18 is provided with a downwardly extending guide pin 22 which extends into the longitudinal opening 25 of the inclined portion 16a of the cuff section 16. The connecting guide 20 is rotatably mounted on one of its ends to the steering pin 23 on the underside 18a of the actuating arm. 18. Its other end is controllable to the cuff rail section 16 via a control pin 24. In Figures 1 and 2, to emphasize the construction, the actuator arm 18 is shown separately from the cuff rail section 16 and the connecting guide member 20.

In the illustrated demonstration example, the coupling guide 20 controls the tamper-proof fuse 26 from the pawl 26b rotatably mounted on the connecting rod via a leaf spring 26a, which then interacts with the bump 26c on the underside of the cuff section 16 when the coupling guide 20 is pivoted. 1 and 2 when the window is tilted. Therefore, the rod section 14 cannot move outwardly through the boss 26c, to the right in FIG. In contrast, when the window is closed, when the connecting guide 20 is parallel to the sash, the control pin 26d movably mounted on the connecting rod section 16 is pushed by the guide 20 against the latch 26a so that it can move around the boss 26c.

Fastening the display arm 18 in a parallel position to

The wing frame (i.e., parallel to the section of the collar rails 16) in the position of the swivel fitting ready to rotate the wing about the vertical axis D results, X, '. ₅ . the interaction of the fixedly mounted thrust member 30 with the control curve 32 on the underside of the actuator arm 18. The plug member 30 may have the shape of a sponge head shown in Figures 1-6, or formed by a substantially circular cylindrical pin (plug member 30. ') of Figures 8-10.

It will be appreciated that the plug member 30 extends through the longitudinal opening 34 of the cuff section 16 and is riveted to the connecting rod section 14.

The plug member 30 need not necessarily be provided on the upper rail 12. It may also be part of the top corner rotation element on the side of the rotatable bearing. Here, reference is made to the patent application entitled "Partially automatically detectable fitting system for windows, doors or the like", filed on the same day as the present application, the content of which is added to the revealed content of the present application. Furthermore, this corner rotation element can also be striking the wing together with the scissor unit 10 described herein also advantageously by means of an assembly machine according to the German patent application also received on the same day called Assembly of parts of fittings supported by assembly machines on window, door, or similar content, the content of which is also added to the revealed content of the present application.

In Figures 1 to 3, the possible positioning positions of the plug member 30 are shown, with an outlined contour line of the ready-to-tilt position KS and a broken out contour line followed by a ready-to-turn position DS and a locked position of VS. In the locked position VS and ready to rotate DS, the plug member 30 is located within the longitudinal bore 38 forming the control curve 32 of the portion of the control curve 40 on the underside 18a of the control arm 18. The control arm 18 cannot therefore rotate from its parallel position around its sash ends (pin 22). It is firmly placed on the wing. In contrast, in a ready-to-tilt position KS, the display arm 18 can rotate around its wing-side end until it adopts a tilt position 18 ', determined by the length of the coupling guide 20 as well as the length of the slot 25 shown in dashed lines in Figure 2. direction of movement. This movement is possible because the plug member 30 slides out of the elongated hole in the tilting position KS

38 thus releasing the exposing arm 18.

The display arm 18 is formed by a first sheet-metal strip section 42 having a flat profile carrying the pins 22 and 23 as well as this rigidly connected by means of two connecting rivets 44 by a second strip-metal strip section 46 (Figures 4 to 7). The thickness of the sheet b of the second bent portion 46 is about 1/3 to 1/2 of the sheet thickness and the first portion 42 2. This reduction in sheet thickness is possible because the downwardly extending arm 46a provides the required mechanical strength, in particular flexural strength. Arm length c

-1146a is about 1/3 of the width d of the exposure arm 18 (i.e.

L-shaped horizontal leg 46b).

The driver portion 40 is interposed in the space formed between the arms 46a and 46b, so that a rectangular cross-section recognizable in Figures 4 to 6 is obtained with an end substantially aligned with the outer edges of the arms 46a and 46b. According to Figures 1 to 3, a portion of the control curve 40 is formed stepwise on its upper side, with a thicker head section 40 and in Figures 1 and 3 a left bearing section 40b. The main section 40a abuts the underside 18a of the exposure arm 18, i.e. the underside of the arm 46b. Its mounting height thus corresponds to the length of the arm c in FIG. 7. The bearing section 40b, on the other hand, has a reduced thickness and abuts on the undersides of the rivet pins 44. A rivet pin 48 which extends between the two rivet pins 44 The bearing section 40b is provided with a semicircular rounded end as shown in Figure 3 to allow rotation about the axis B even though the arm 46a is adjacent laterally.

At the opposite end of the portion of the control curve 40, the adjustment spindle 50 is mounted within the block 52 rotatably about an axis C perpendicular to the longitudinal direction L and parallel to the arm 46b. It engages in a correspondingly formed toothing 54 at the inclined end of the main section 40a of the control curve section 40. By rotating the spindle 50 by means of a rotating tool tucked into the polygonal recess 50a at the spindle end diverted from the arm 46a,

-12 rotate clockwise around C axis; the corresponding rotated position 40 'is indicated by a dotted outline in Figure 3. In order to also rotate the parallel position of a portion of the control curve 40 with respect to the actuator arm in the opposite direction from the direction shown in FIG. 3, the main section 40a in the direction of the spindle 50 is provided with slightly adjacent side surfaces 56.

The main section of the control curve portion 40 has a central recess 60 extending parallel to the longitudinal direction of the control curve portion 40. it is exposed by the arm 46b. Due to the recess 60, a recognizable cross-sectional shape (upwardly open U-shape) is obtained in Figures 4 to 6. The left side U-arm 62a is urging or has a corresponding horizontal distance to the arm 46a, as adjusted by the adjusting spindle 50. The opposite side arm 62b more or less accurately aligns with the edge of the arm 46b. A longitudinal opening 38 is formed in the central U-shaped arm 62c, which extends in the longitudinal direction of a portion of the control curve 40, and at its left end in FIG. Since here too the side arm 62b is completely interrupted by the recess 64, in the ready-to-tilt position KS of the male member 30 of Figure 4, the portion of the control curve 40 together with the actuating arm 18 can be displaced in the direction of arrow A by the male member 30. This movement occurs, as already mentioned, with the tilting opening of the wing.

Figures 4 to 6 show that the plug member 30 can assume a different height position relative to the actuator arm 18 without compromising functional reliability. The tolerance range corresponds to the height of the shoulder c, after subtracting the thickness e of the middle γ ~ 5 ‘“ arm ”~ 2 'and ~ after the height ´f’ vyβ you 3 3 a height is deducted. * diameter of the sponge head plug-in member 30.

i ť

The last reading f is omitted when, in the embodiment of Figures 8 to 10, the male member 30 'is used in the form of a substantially circular cylindrical pin.

And, of course, when the plug member 30 is still somewhat higher than that shown in FIG. 5 relative to the control curve portion 40, in order to achieve a smooth run-in of the plug member 30 and FIG. 3 0 to ¹ part of control cam 40, the edge of the arm 46b to be provided with a corresponding slant 66th

In order to selectively vary the effective length of the actuator arm 18, especially when the sash would drop slightly after prolonged use, the adjusting device 70 is provided at the end of the actuator arm close to the pivot axis, e.g. This is formed by an adjusting screw 72 which is mounted in the aforementioned block 52 rotatably about an axis E parallel to the longitudinal direction L of the actuating arm 18, but axially non-movable.

For this purpose, the adjusting screw 72 is inserted into the corresponding cylindrical bore of the block 52. The axial fastening is achieved by means of a pin 74 which is inserted into the block 52 and extends into the circumferential groove 72a of the adjusting screw 72.

14The other two pins 76 serve to guide the adjusting screw 42 laterally.

The male thread portion 72b in Figure 3 of the right end of the adjusting screw 72 extends into the corresponding passing internal thread of the adjusting portion 78. The adjusting portion 78 has an arm 78a projecting downward in Figure 1. In this plan view, the Z-shaped portion 80 is fastened to the plan view of Figure 2 and is provided at its free end with a bearing sleeve 80a as part of the upper pivot bearing of the wing 82. In Figure 7, the portion 80 is omitted for simplicity.

For the space-saving, yet reliable guiding of the adjusting portion 78 on the display arm, the adjusting portion 78 is provided with an upwardly projecting leading projection 78b. It extends into the notch 84 in the arm 46b according to FIG. The notch extends in the longitudinal direction L and is so dimensioned that the desired range for the effective length of the exposure arm 18 is available. To adjust the length, the adjusting screw 72 is rotated correspondingly by means of a rotating tool inserted into the recess 72c at the outer end of the adjusting screw 72. When mounting the sash to a fixed frame, part of the control curve 40 may rotate from its indicated parallel position by rotating the spindle 50. a reliable interaction of a portion of the control curve 40 and the plug member 30, particularly a reliable wing pressure, has been achieved.

Thus, the exhibited scissor unit is provided with a plug member 30 on the upper rail or the rail. on the corner rotation element,
