DE1584225C3 - Opening device for tilt-lift-swivel sash - Google Patents

Description

The invention relates to a deployment device for tilt-lift-swivel wings with one on the upper one Wing edge arranged, with its one end in the vertical pivot axis of the wing on the stationary Frame rotatably mounted and its other end on the sash slidably guided, the opening movement limiting extension arm, with an additional arm connected to the extension arm and the sash and with coupling links with beveled tightening surfaces through which the extension arm can be locked to the sash is, wherein the coupling members one in the area of the pivot bearing end of the extension arm on Wings include attached approach.

A display device of this type is known from utility model 18 24 257. With this well-known Two separately operable edge bolt locks are provided, with the over a first handle actuatable edge latch for locking the opening side of the sash serves, while the second edge bolt lock, which can be actuated by a second handle, serves to to move a safety bolt vertically back and forth between two positions, namely between one position, in which this locking bolt locks a tilt plate and thereby enables the sash to rotate sideways, and another position in which this locking bolt releases the tilt plate and thus the tilting of the wing. The locking bolt is in the area of the pivot bearing end of the tilt actuator attached and has an inclined tightening surface that cooperates with the extension arm when the safety catch is pushed up by means of the edge gear.

The main disadvantage of this known opening device is the fact that it is used for locking of the tilt actuator required edge gear, the manufacturing costs of an opening device in undesirable Way increased and that in spite of this comparatively

ίο No security against incorrect operation at all, at great expense is achieved because the locking bolt in every operating position and especially in the pivoted position can be operated. In the case of heavy sashes in particular, unintentional operating errors i.e. due to incorrect actuation of the edge gear provided for locking the tilt actuator, considerable dangers arise.

Another display device of a comparable type is known from DE-PS 10 17 942. With this well-known Arrangement, the wing from its lowered closed position in a middle tilted position and a upper pivot position can be raised. LJm a lifting of the wing in spite of having one end perpendicular To enable pivot axis of the sash on the fixed frame pivoted extension arm, is this extension arm by means of a pivot attached to its end in a stationary Frame attached bearing sleeve slidably guided.

Below this bearing sleeve is a hinge sleeve with an upper and a lower one on the wing Bolt arranged, the upper bolt engaging in the bearing sleeve in the pivoted position of the wing, in which the pivot of the extension arm is also guided. During the swing movement of the wing the extension arm is inactive, d. H. it has no function whatsoever in connection with panning the Wing. In the middle position, i.e. H. in the tilted position of the sash the bolts of the hinge sleeve are free, and the hinge pin slidably guided in the bearing sleeve, which when the door is lowered by an am Hook attached to the wing is taken along, holds the extension arm that limits the extension movement. When the sash is fully lowered, a lower hinge pin engages in the previously mentioned hinge sleeve another sleeve fixedly attached to the frame, which ensures that the wing against the Frame is pressed. In this lowered position of the wing, the function of pressing is thus performed of the sash to the frame from a special fitting and not from the one that supports the extension arm Pivot taken over with the associated bearing sleeve.

The main disadvantage of this known opening device is that to ensure the pivoting movement and the pressing of the wing against the frame in view of the simplicity of this type, which is always sought Ausstellvorrichtungen unwanted additional BescWagteile are required. It is annoying with the known Ausstellvorrichtung also that the hinge pin of these additional fittings always at least partially exposed, with the danger because of the lubricants that are always on these pins from soiling, especially from curtains.

From the German utility model 17 87 115 is an opening device for tilt-lift-swivel sash known from windows, doors and the like, in the case of the

Ren wing edge two extension arms are provided, of which the pivot axis-side extension arm mounted with one end at a distance from the vertical pivot axis on the frame and with his the other end is slidably guided on the wing. The extension arm further removed from the vertical pivot axis is rotatably mounted on the upper edge of the sash and slidably guided on the fixed frame. To a To allow pivoting of the wing in the raised position, the guidance of the last mentioned Extension arm on the fixed frame has a recess through which the corresponding guide pin of the extension arm can emerge in the raised, closed position of the pivoting sash. To prevent, that this extension arm is then only held at one end during the pivoting movement of the window executes uncontrolled and disruptive movements, is between this extension arm and the upper wing edge a coupling in the form of a cooperating with a corresponding hole cylindrical bolt provided. This clutch, which is released when the swivel vane is lowered only has the aforementioned purpose, which is inactive in the pivoting position of the wing to hold one end rotatably mounted extension arm, in such a way that this arm also back into the corresponding recess of its leadership can be brought when the sash is pressed against the frame and is lowered again.

From the German utility model 17 24 724 is an extension arm for lift-tilt and turn windows or Revolving doors known in which the pivot pin of an extension arm when lifting the window sash out of its Storage on the fixed frame is slidable. This is provided because the pivot axis of the Wing is located on the opposite side of the frame or wing and accordingly a pivot of the wing in the raised position is only possible if the connection between the pivot pin of the Extension arm and the associated bearing sleeve is released beforehand. If the connection between the Pivot pin of the raising arm and its storage pivoting of the then only supported at one end To avoid the extension arm, there is a clamp on the window frame to hold this extension arm in place arranged This construction is again complex and with regard to the every lifting and lowering process required insertion of the pivot pin in its storage also susceptible to failure.

From DE-PS 9 41 413 a fitting for either pivotable about a vertical axis or about a horizontal axis tiltable sashes of windows, doors or the like with one in particular also as an extension support serving handlebars known, which in the extension of the vertical axis on the fixed frame and is hinged to the upper edge of the wing, the upper lateral pivot bearing forming, in particular also serving as a support arm with the wing in the vicinity of the vertical axis form-fitting can be coupled For this coupling of the handlebar to the wing, one is by means of an additional Handle operated, arranged on the wing locking bar provided. This locking bar must be made the coupling between the handlebar and the wing in alignable openings in the handlebar and one on the Wing attached fitting are introduced. A fitting of this type is in turn relatively expensive and especially not to be used for tilt-lift-swivel sashes.

From the Austrian patent 1 95 795 a locking device for pivoting sash is known, which are provided with a deployment device that tilts the pivoted about its vertical axis Sash automatically prevented from this vertical axis in the direction of the wing plane even in the event of incorrect operation. For this purpose, in the known locking device, one locking part is the one in the vertical

ίο pivot axis arranged locking device is essentially hook-shaped with an open cross-section towards the other locking part, and this other locking part by means of a projection engaging from the open side engages the hook-shaped locking part in such a way that both locking parts are perpendicular when the sash is pivoted about one Rotate pivot axis lying contact point or roll around this pivot axis on each other. This known locking device is expensive, even if the relative sliding of one locking part is carried out by lifting the entire wing together with the relevant locking part in lifting-turn-tilting wings, since the locking device must consist of two comparatively complicated parts and thus both the manufacturing costs and, above all, the assembly costs of the entire fitting are adversely affected by this locking device.
The object of the invention is to create a deployment device for tilt-lift-swivel sash of the type mentioned, which is structurally particularly simple and can be manufactured without the use of additional actuating rods and still ensures a high level of operational reliability.

This object is achieved according to the invention in that the coupling members are through the lifting or Lowering movement of the wing can be locked or unlocked and that the approach with the wing at its the perpendicular Pivot axis adjacent edge surface is firmly connected.

Through this measure, on the one hand, by switching off possible operating errors, the desired A high level of safety is achieved and, on the other hand, a multiple function is assigned to the extension arm at the same time, because it is not only active during the tilting process, but above all also during the pivoting process is actively effective, which in turn has the consequence that the opening device is structurally extremely simple overall will. This has in view of such

so issuing devices customary in large numbers of considerable importance.

The lifting or lowering movement of the wing is not only in connection with the beveled surfaces the coupling links to ensure that the sash rests properly on the frame when it is raised Wing used, but it is this Hebebzw. Lowering movement also at the same time to achieve a positive locking or unlocking between the extension arm and sash is used, namely without the need for any additional locking elements. It is also important that all these advantages can be achieved through particularly simple hardware components. Such a simple fitting component also represents the one in the area of the pivot bearing end of the extension arm on the sash attached, a suit inclined surface having and cooperating with the extension arm approach that despite its simple design and its

problem-free assembly in connection with the utilization of the lifting and lowering movement of the sash together with the extension arm forms a locking unit that cannot be operated incorrectly.

Another advantageous embodiment of the invention is characterized in that coupling members are provided on the one hand from cylindrical pins with a conical or spherical head, which on the side of the extension arm opposite the upper end face of the wing is arranged, and on the other hand, consist of holes provided on the upper end face of the wing.

By distributing the coupling members over the length of the extension arm, a relative large suit received, d. H. a relatively large area within which the wing can be pulled towards the fixed frame is made possible and thereby in turn the handling and operational safety of the Overall device is improved.

In another embodiment, the bores are at least partially conical.

Exemplary embodiments of the invention are shown in the drawing. Here shows

F i g. 1 the side view of the uppermost part of the lowered sash with the opening device,

F i g. 2 the top view of this with the sash tilted at the same time or (in dash-dotted lines) when the sash is closed Wing,

F i g. 3 shows an enlarged illustration of the area indicated by the circle 3 in FIG. 1 marked point, namely before the engagement of coupling element and counter coupling element begins if the sash is not firmly closed,

F i g. 4 shows the same representation for the by the circle 4 in F i g. 1 marked point, where approximately the same position of the wing as assumed in Fig.3 is, where FIG. 3 and 4 a section perpendicular to FIG. 1 play.

F i g. 5 shows the partial view of a further embodiment, partly in section, also with the lowered Wing,

F i g. 6 shows a section along line 6-6 in FIG. 5, with the not fully closed, d. H. to the fixed Frame not firmly pressed on sash, and

F i g. 7 shows the same representation as FIG. 6, but with the sash raised and therefore fully closed. In Fig. 1 and 2, 10 denotes the fixed frame, 11 denotes the wing. The frame and sash are connected to one another by an extension arm 12 which is again supported against the sash by an additional arm 13. The extension arm 12 is, for. B. by means of an angle piece 14, with which it is firmly connected, mounted in the vertical pivot axis AA on the fixed frame 10 in the bearing 15 by means of hinge pin 16. A longitudinal rail 17 having the articulation points of the extension arm 12 and the additional arm 13 extends along the upper edge of the wing 11 and is fastened to it by screws.

A hinge pin 18 is used to articulate the extension arm 12 on the wing 11, which is inserted in a slot 19 in the longitudinal rail 17 is guided displaceably in the longitudinal direction of the wing edge. A hinge pin 20 connects the additional arm 13 with the extension arm 12, a hinge pin 21 the additional arm 13 with the rail 17 on Wing. The pin 18 is here with a widened head 18a, the slot 19 with an extension 19a provided so that the hinge pin 18 can be lifted out of the slot 19 when the wing is in closed and raised position, but otherwise due to the widened head 18a on one Exit from the slot is prevented.

The hinge pin 20 is also designed as a coupling element. He owns for this purpose how in particular F i g. 3 shows a conical head 22, e.g. B. is rounded at its tip. He works with one conical bore 23, which is provided in the longitudinal rail 17, and the mating coupling element to the coupling element 22 forms. The conical bore 23 is arranged so that it is raised and closed Wing, d. H. in a position 17 'of the longitudinal rail 17 (Figure 2) at the point of then the Position 20 'occupying hinge pin 20 is located and is in engagement with this.

Furthermore, coupling pins 24 and 25 are arranged on the extension arm 12, for example, which with the Bores 26 and 27 acting as counter-coupling elements on the wing or on the rail 17 cooperate. The coupling pins are essentially cylindrical, but with a conical tip 28, so that, if the central position is not exactly centered, they come to the same diameter bore 26 (or 27) can center yourself.

If the wing from the in F i g. 2 is reset to the closed position, so when the wing has fully reached its closed position, so is firmly pressed against the fixed frame 10, the coupling elements 20,24 and 25 easily with the acting as counter-coupling elements bores 23, 26 and -27 coupling. If, however, as is often the case, the sash is not pressed firmly against the stationary frame, then when the sash is lifted, for example, the results shown in FIG. 3 and 4, shown relative positions of the extension arm 12 to the longitudinal rail 17. If the wing is raised from this position, the conical head 22 of the pivot pin 20 first comes into contact with the inclined side surface of the conical bore 23. The tilting arm 13 is pulled through the inclined surface in the direction of the arrow χ into the conical bore 23 until the coupling pin or pivot pin; Zen 20 is located centrally in the conical bore 23: is. The extension arm 12 thus has its correct ord-; Appropriate position reached relative to the wing, ie the wing has been used at the same time on the fixed frame. ;

In order to ensure a safe and inevitable coupling over its entire length in spite of the resilience of the extension arm, the coupling pins 24 and 25 already described are also provided. During the movement of the coupling pin 20 in the direction of the arrow χ , the coupling pin 24 has also moved in the direction of the arrow x \ until it touches the outer edge of the bore 26 in the position 24 'by means of its conical end 28. When the wing is raised further, the pin slides through the wedge winding of the conical end into the cylindrical bore 26 and is locked in this, as indicated by the position 24 "j. The same applies to the locking pin 25 with regard to its coupling with hole 27.

In the embodiment according to FIG. 5 to 7 are corresponding Parts are provided with the same reference numerals as in the previous exemplary embodiment. Instead of a coupling pin 25 is provided in this case an approach 29a of a flat iron 29, which through Screws 30 is attached to a vertical edge of the wing and over the rail 17 with its the an

sentence 29a forming end protrudes. This end has an inclined surface 31 and a downward one on it subsequent vertical surface 32.

If the wing 11, as indicated in Fig. 6, not properly closed, when the wing 11 is raised, the inclined edge 31 strikes against the Extension arm 12 or the z. B. by riveting, welding or the like. Fixed angle part 14 and thereby presses the wing 11 inwards against the fixed frame 10 until the extension arm 12

arrives at the perpendicular surface 32. In this position, the sash is firmly closed in that at the same time the extension arm locks the sash against outward movement perpendicular to the plane of the frame, as shown in FIG. 7 is shown. Even with large pressures acting on the wing 11 in the direction of arrow P , the wing can no longer be decoupled from the extension arm 12, since this is between the extension 29a or the vertical surface 32 of the same and the rollover 11a

ίο of the flight ice is fixed positively.
