DE3343366A1 - Fitting for the sliding wing of windows or doors - Google Patents

Abstract

What is provided is a fitting for sliding wings of windows and doors, which can be fastened solely to the overpiece of the window wing, so that no cutting work or the like on the wing profile is necessary in order to mount it. The lower pivoting-arm arrangements, together with their screw-on plate and the running-roller holders for the rollers running on a lower running rail, form a distortion-resistant unit, in that the two running-roller holders are connected to one another in a distortion-resistant manner, the lower end of the wing being supported on this distortion-resistant unit and thus being prevented from skewing during the opening and closing. Correspondingly, there are preferably provided for the upper part of the wing two pivoting-arm arrangements with pivoting arms which, on the one hand, are firmly articulated on the overpiece of the wing and, on the other hand, are articulated on a common rail which is itself guided displaceably on an upper guide rail of the fitting.

Description

"Hardware for the sliding sash of windows or doors"

The invention relates to a fitting for the sliding sash of windows or doors with the features of the preamble of claim 1.

Fittings of this type are well known. In one embodiment the extension arm arrangements are attached with their extension arms in the rebate of the window. This makes it necessary at least in the area in which the arms come out of the fold step out to provide millings on the profile material of the sash. Included the extension arms can be hinged to the roll holders. Surrender in any case considerable expenses in the fitting itself and in its installation.

There is also the risk of tilting when the sash is opened of the sash occurs when the opening is done by hand and not by a Override control is controlled, which in turn increases the complexity of the fitting. However, tilting the sash makes it difficult to operate a locking linkage, because their locking pins are no longer evenly L in the appropriate Locking recesses can occur (see. DE-OS 30 27 835, DE-PS 29 41 109). It is also known, upper and lower lying in vertical alignment of the same type Extension arms pivot with each other through a shaft guided through the Flürel profile to couple and in a horizontal plane side by side extension arms Via a drive connection such as a rope, chain or connecting rod or the like. With each other to combine to ensure that all four extension arms of the sash move evenly to ensure. This arrangement is also extremely complex and required the use of wing profiles that differ greatly from normal profiles and also require intensive processing.

In contrast, it is the object of the invention to provide a fitting with the features to develop the generic term so that it is much easier to use, without the need for complex machining of the wing profiles and the simpler one Design a reliable, torsion-free opening of a sash also by means of Hand assured.

This object is achieved by the features of claim 1.

All parts of the new fitting can be easily attached Fasten the flap of the sash, so that no machining is done on the sash profile either As is necessary on the aperture profile to a significant extent. For fixing screw-on parts can be used, which flap the sash in the direction of parallel to the wing plane as well as perpendicular to it at an angle and thus essential contribute to the torsional stiffness of the lower area of the sash. At These screw-on parts are the ends of the extension arm and one or two Articulated auxiliary arms of the extension arm arrangements. The extension arms for their part are with its other end over the associated roller holder in such a way torsionally rigid connected to each other that the extension arms of the extension arm assemblies lie in the closed position of the sash in front of the front frame plane and stand there perpendicular. This vertical arrangement of the actual extension arms in the closed position it is achieved that the extension arm only one when opening needs to cover a relatively small pivoting path.

The lower swing arm arrangements can also be used for the upper area of the wing may be provided. Advantageously, however, the two above exist Swivel arm assemblies each consist of a firmly articulated on the upper overlay of the wing Swivel arm, the ends of these swivel arms on the frame side at a common Connecting rail are articulated, which are slidably guided on the guide rail is. This allows the upper swivel arm arrangements as well as the lower raising arm arrangements Mount it quickly and easily on the window overlap without any milling work on the window. Without further override controls it is guaranteed that when opening and closing the sliding sash moves in the same direction at all corners perpendicular to the window level and not in awe, even if the Movement of the wing by hand he follows. The arrangement is particularly suitable for large wings with a high weight, because the new fitting makes it very easy to operate the sliding sash goes.

To cover the extension arm arrangements, the screw-on part can according to Kind of one that covers the extension arm arrangements at least towards the interior of the room Housing be formed.

Due to the compulsory movement of the sash in the same direction when closing and open it is easily possible with a commercially available all-round closure several locking pins to be provided, which can be brought into three positions, so that the sliding sash is locked in the closed position, in a Ventilation position released all around except for the underside of the locking linkage so that the wing can be tilted around the lower runner and in one third position is released all around, so that the sliding sash is pulled vertically and can be moved sideways.

Of the two upper swing arm assemblies, at least one can have the usual push-off spring, so that when the locking linkage is actuated in the middle position, the upper side of the sash is automatically removed from the frame is pulled. With the help of the push-off spring and the wing weight, the wing arrives in the third position almost automatically into the plane perpendicular to the frame plane pulled Position and only needs to be moved laterally from this to become. To close, the sash must be pressed shut by hand. Due to the This is possible without great effort in the form of the extension arm arrangements. A kinking of the wing is excluded even if the wing is only is pressed on one side.

The invention is based on schematic drawings an exemplary embodiment explained in more detail.

They show: FIG. 1 a plan view of the closed wing, the is equipped with the fitting according to the invention.

FIG. 2 shows a vertical section with a view of the fitting in FIG the closed position of the sash.

FIG. 3 shows the ventilation position in the same representation as in FIG of the wing.

Figure 4 in a view from above the upper fitting parts in the ventilation or open the sash.

FIG. 5 shows the wing completely in the same representation as FIG depressed position.

Figure 6 is a vertical section parallel to the plane of the wing through the fitting and FIG. 7 in detail a cross section along the line A-A in Fig. 6.

The window of Fig. 1 has a fixed wing 2 and a Sliding leaf 1 open. The sliding sash is in the closed position shown in FIG. 1 in the same plane as the fixed wing 2. He can be in front of this fixed wing 2 slide along the upper guide rail 9 and the lower running rail 8. To support the wing on the lower running rail 8 there are roller arrangements and lower extension arm assemblies 4 and 5 provided, while for the guidance of the At the top of the wing two upper swing arm assemblies 6 and 7 are provided. With 3 a handle for actuating a conventional all-round closure is shown, the locks the wing 1 in the closed position on the frame 10 with its locking pin.

The lower extension arm arrangements 4 and 5 each have a screw-on part 15 on. This is attached to the flap 35 of the wing and overlaps each at the lower corner area of the overlap this both in the direction parallel to the plane of the wing as well as angularly in the direction perpendicular thereto, as shown in particular. FIGS. 6 and 7 show. The horizontal leg 16 extends by a noticeable length over the underside of the rollover, this length being shown in the example corresponds to the length of roller holders 20a, 20b in which pairs of rollers 21 are rotatable are stored, which are supported out on the lower running rail 8.

An extension arm 11 is attached to one end of the screw-on part and an auxiliary arm 13 articulated. The articulation end 12 of the extension arm 11 is in one Longitudinal section 12a of the screw-on part 15 is displaceable, while the articulation end 14 of the HilSsarmes 13 is firmly hinged to the screw-on part. Instead of directly, the connecting end can 12 of the extension arm 11 is also articulated to the screw-on part via a second auxiliary arm be.

The lower end of the extension arm 11 is rigid with the roll holder 20 connected, as in particular Fig. 5 shows, the connection between the roll holder and the extension arm takes place so that the longitudinal center line of the extension arm 11 below runs at an angle other than 900 to the axis of the roller 21. The lower one Running rail 8 is firmly screwed to the room-side surface 27 of the window frame. The arrangement is such that in the closed position according to FIG. 2, the raising arms 11 lie in front of the room-side plane 27 of the window frame and stand perpendicular. This results in a relatively small pivoting path for the extension arms in the Movement between the positions according to FIGS. 1 and 5.

As shown in Fig. 6, the two roll holders 20a and 20b by a Rail or rod 30 rigidly connected to one another in a torsion-resistant manner. Form with it the screw-on parts 15, the two extension arm assemblies 4 and 5 and the interconnected roller holders 20a and 20b have a torsion-resistant Unit on which the lower end of the wing is securely supported, as follows: that a lurching of the temple in its movements cannot occur even then, if the corresponding forces on the sash are only applied on one side, e.g. by hand as the force exerted on one extension arm is transferred to the other arm is At the upper end of the wing, similar extension arm arrangements such as the raising arm assemblies 4 and 5 may be provided.

In the example shown, however, is preferred to hold the The upper end of the wing uses a swing arm assembly which, like Figs 4 shows, consists of two pivot arms 6 and 7, which on the one hand by means of screw-on members are firmly hinged to the upper window flap 35a, while their frame side Ends are hinged to a common slide 32, which in turn on the upper guide rail 9 is slidable. At least one swivel arm, e.g. the Swivel arm, a push-off spring 33 of a known type can be assigned, which when actuated of the locking lever 3 and releasing the upper end of the wing the upper end automatically from the closed position into the ventilation position according to FIG. 3.

The lever 3, which can be moved in three positions, becomes a common one All-round closure with operating rods 26 and Locking pin 25 actuated. In the position according to FIG. 2, the all-round lock locks the wing in the closed position on all sides. Only the lower one remains in the second position End of the wing locked as shown in FIG. 3, so that the wing around the rollers 21 and the running rail 8 can pivot into the tilted position. In the third position of the all-round closure, the locking pins 25 free the sash on all sides, so that now the lower end of the wing 1 practically by itself from the Position according to FIG. 3 can swing out into the position according to FIG. 5, so that the wing can easily be moved sideways in front of the fixed wing 2.

As FIG. 7 shows, the screw-on part 15 can be in the manner of a cover housing be extended to the members of the deployment arm assembly 4 and 5 at least for To cover the inside of the room.

For this purpose, the screw-on part 15 by the leg 17 in the Cross-section T-shaped widened (not shown) or (as shown) with the screw-on plate to form an overall U-shaped housing that extends over the legs 17 and 18, the members of the swivel arm assembly 4 not for the interior of the room but also cover the side.

According to FIG. 5, the milf arm or arms 13 can also be controlled by a control cam 12b and a pin 12c engaging in this on the screw-on part 15 and the extension arm 11 must be replaced. The control cam prevents the wing from moving vertically Direction when the extension arm 11 is pivoted out or in.
