Abstract

What is described is a setting-out device 50 for the wings of windows, doors or the like, consisting of a bearing rail 51 to be fastened in the rebate on the frame side and of a holding rail 52 likewise engaging in the rebate on the wing side as well as of two links 6 and 7, of which one link 6 engages only pivotably 3' and 3'' both on the holding rail 52 and on the bearing rail 51, whilst the other link 7 is held in pivoting and displaceable guide engagement 4'/8' or 4''/8'' both with the holding rail 52 and with the bearing rail 51. So that, when the wing is locked on the fixed frame in the closed position, the sealing pressure force of the wing on the fixed frame counteracts a penetration of draught air and rainwater even in the region of installation of the setting-out device 50, that is to say on the joint or fastening side of the window or door, the pivoting and displaceable guide engagement 4'/8' of the second link 7 on the bearing rail 51 has a sliding piece 59 which runs between longitudinal webs 51' of the latter, for example on the underside of the bearing rail 51, and which carries at one end a locking extension 67 which, in the closing or rest position of the links 6 and 7, is engaged with low play into a fixed locking engagement 68 of the bearing rail 51. <IMAGE>

Description

The invention relates to an opening device for the sash of windows, doors or the like, consisting of a mounting rail to be fixed in the frame on the frame side and a mounting rail on the wing side, also in the fold, and two handlebars, one of which is attached to the mounting rail as well only acts on the bearing rail such that it can pivot, while the other link is held in pivotally displaceable guide engagement both with the holding rail and with the bearing rail.

Display devices with these features are already known and are the subject of DE-OS 39 19 970, DE-GM 89 12 421 and DE-GM 90 01 629, for example.

Just as with an opening device for windows with skylight folding sash, which has become known from US Pat. No. 3,722,142, both links are also held in direct connection with one another by a connecting bolt in the manner of so-called cross shears in the aforementioned opening devices. This ensures that the opening and closing movement of the sash not only moves away from the plane of the frame with its rollover in the normal direction, but also translates in the direction parallel to the plane of the frame.

All these known Ausstellvorrichungen the peculiar advantage that when the wing is in the closed position on the frame not only the two links, but also the coupling and support rails coupled with it are completely hidden between the folded surfaces of the wing and the fixed frame and are aligned parallel to each other. Since both the handlebars and the bearing and holding rails are only a width of max. 20 mm, the opening device can be easily accommodated in the airspace of today's usual - with normal folds - windows and doors.

While in the installation area of the opening devices, i.e. on the hinge side of the window or the door, the sealing system of the leaf in the closed position on the window frame is mainly caused by the kinematics of the opening devices themselves, to secure the sealing system, at least on the locking side between the leaf and the frame, that is, special locking devices can be used at the locations remote from the display devices, which can be forcibly engaged and disengaged by manual operation of a handle.

These locking devices are designed to be adjustable on a regular basis and thus make it possible to exert a sealing pressure on the wing locked in the closed position in the installation area of the locking devices, which is sufficient to prevent the penetration of drafts and, if applicable, rainwater from outside to inside even when wind pressure occurs .

Since five different joints cooperate in each generic opening device between the wing and the fixed frame, each of which must have a certain minimum clearance to ensure a jam-free opening and closing movement of the wing, it can happen that the hinge side of the window or the door Sealing pressure of the wing on the fixed frame does not meet the wishes or requirements set there.

For this reason, in the display device according to DE-GM 90 01 629, the handlebar, which is only pivotably mounted, is connected to the holding rail with its second joint, which acts on the wing, to a limited extent and can be adjusted transversely. The joint consists of an eccentric pin which is stiffly rotatable in connection with the handlebar and can be detachably connected to a bearing bush of the holding rail. Below the bearing bush, the eccentric pin has a collar that has tool engagement surfaces, e.g. for an open-end wrench, so that it can be adjusted with difficulty relative to the handlebar. Since the eccentricity of the eccentric pin can only be dimensioned relatively small due to the limited space available, the adjustment that can be made via the eccentric pin is not sufficient in any case to bring about a sufficiently large contact pressure adjustment of the sash relative to the fixed frame.

It has now been found that the contact pressure adjustment for the wing in the area of the articulation-side opening devices can be considerably improved in that, according to the invention, the pivotable guide engagement of the second link on the -frame-side bearing rail between longitudinal webs of the bearing rail, e.g. on the underside of which has a running slider which carries at one end a locking lug which is engaged with little play in a fixed locking engagement of the bearing rail in the closed or rest position of the handlebars.

An additional tensioning force is exerted on the first, only pivotably mounted handlebar by the measures specified, with the cooperation of the locking devices engaged on the locking side via the wing and the second link now clamped free of play, as well as the joint of both links. This transmits a higher force to the wing via its second joint and the holding rail and thus improves its closing pressure in the area of the opening devices.

It has proven itself according to the invention if the latch attachment is formed by a flat nose protruding from the slide, while the latch engagement consists of a claw seated on the bearing rail or on a base which can be coupled to it.

Finally, it can also prove to be useful if the other end of the slider is at a distance from the joint of the handlebar that is greater than the distance from the free end of the nose from this joint. This measure further improves the bearing clearance effect.

The drawing shows in Fig. 1 a schematic representation of a window or a French window, in which the frame 2 rests on the frame 1 in its closed position. In Fig. 2 the same window or the same window door is shown; however, here the sash 2 is brought into the rotational opening position relative to the frame 1 by joints 3 ′, 3 ″ and 4 ′, 4 ″ directed parallel to its upright side edge.

From Fig. 3 of the drawing it can finally be seen that the window or the window door can also be designed as a tilt and turn window or door, the sash 2 in its tilt opening position relative to the frame 1 and its tilt opening width by a tilt and turn opening device 5 is limited, which can be installed between the upper, horizontal bars of frame 1 and sash 2.

The opening device 5 also acts via joints 3 ', 3' 'and 4', 4 '' together with the window frame 1, while the bottom-lying pivot between the wing 2 and frame 3 pivot bearing in its kinematic design with Fig. 2 of the drawing matches.

The joints 3 ', 3''and4', 4 '' are provided in one and the same arrangement and design both in the area of the upper horizontal folds and in the area of the lower horizontal folds between frame 1 and sash 2 in such a way that their axes each run parallel to the upright boundary edges of frame 1 and sash 2.

The joints 3 ′ and 3 ″ are each located at the ends of a link 6, the joint 3 ′ acting exclusively on the frame 1 in a pivotable manner and the joint 3 ″ also exclusively acting on the wing 2 in a pivotable manner. The joints 4 'and 4' 'are each provided at the ends of a second link 7, the joint 4' engaging in a sliding slot 8 'oriented parallel to the plane of the frame 1, while the joint 4' 'in a corresponding manner with a sliding slot 8 '' is in engagement connection, which is located on the wing 2 with its position aligned parallel to its plane. The sliding joint 4 '/ 8' is thereby formed on the frame 1 and the sliding joint 4 '' / 8 '' is formed on the sash 2.

Both links 6 and 7 are in turn in constant communication with each other by means of a swivel joint 9 in the manner of a pair of cross-cutters, the common swivel joint 9 of the two links 6 and 7 on the link 6 being a smaller distance from the joint 3 ″ than from the joint 3 ′ and link 7 has a smaller distance from the joint 4 'than from the joint 4' '.

It is important that, on the one hand, the swivel joint 3 'and the sliding joint 4' / 8 'on the frame 1 and, on the other hand, the swivel joint 3''and the sliding joint 4''/8''on the sash 2 are provided in an always precisely fixed position assignment to one another if the functional mobility of the wing 2 with respect to the frame 1 is to be ensured. Therefore, the deployment device 50 formed by the two control arms 6 and 7 is equipped on the one hand with a bearing rail 51 for attachment to the frame 1 and on the other hand with a holding rail 52 for attachment to the sash 2, as can be seen in FIG. 4.

The bearing rail 51 on the one hand forms the support for the swivel joint 3 'of the handlebar 6 and on the other hand contains the sliding joint 4' / 8 'for the handlebar 7. On the other hand, the holding rail 52 contains the swivel joint 3' 'for the handlebar 6 and on the other hand equipped with the sliding joint 4 '' / 8 '' for the handlebar 7.

In the case of a window or a window door with rotating sashes, two opening devices 50, which are identical per se, but mirror-inverted in terms of their design, are installed between the lower horizontal and the upper horizontal rebate circumferential surfaces of the frame 1 and sash 2, concealed. In each case, the bearing rail 51 lies against the horizontal folded peripheral surface of the frame 1, while the holding rail 52 is embedded in a profile groove on the folded peripheral surface of the wing 2.

In a window or a window door with tilt-and-turn sash 2, an opening device 50 is used as the tilt-and-turn corner bearing between the lower horizontal rebate peripheral surfaces of the frame 1 and sash 2, which fully matches the opening devices 50 for the sash. However, the opening device 50 for the tilt-and-turn sash arranged between the upper horizontal fold peripheral surfaces of the frame 1 and sash 2 is designed such that the opening arm 5 ′ of the tilt-and-turn opening device 5 takes the place of the holding rails 52 arranged on the wing side, as shown in FIG. 3 of the drawing is indicated. The swivel joint 3 ″ of the link 6 and the sliding joint 4 ″ / 5 ″ for the link 1 of the opening device 50 there are therefore provided on or in the opening arm 5 ′.

The same opening devices 50 are used for installation in windows with tilting or folding sashes, as are provided for windows and doors with rotating sashes. In this case, however, they are installed in a concealed manner between the upright fold peripheral surfaces of the frame 1 and sash 2.

With all of the above-mentioned opening types for windows, doors or the like, it is essential that the sash 2 can be precisely adjusted in relation to the frame 1 with as few simple steps as possible, so without any problems. Such an adjustment of the wing 2 relative to the frame 1 is not only necessary when carrying out the stop work and / or when installing the windows and doors in a building for the first time. Rather, it must also be possible at any time later in order to be able to compensate for or eliminate the changes in position that are unavoidable in practical use — the setting of the wing 2 relative to the frame 1. 4, for this purpose, the joint 3 'of the link 6 is seated on a slide 31 which is guided on the bearing rail 51 with limited longitudinal movement, for example in a profile of approximately U-shaped cross section thereof.

An eccentric 39 serves as an adjusting member for the slide 31 relative to the bearing rail 51, which is stiffly rotatable on the slide 31 and is in permanent engagement with an elongated hole 40 directed in the transverse direction of the bearing rail 51.

By turning the eccentric 39, for example with the aid of a screwdriver or socket wrench, a sensitive and form-fitting position adjustment of the joint 3 'for the handlebar 6 and thus the entire opening device 50 can be brought about relative to its bearing rail 51 rigidly fastened to the frame 1, and without that their mounting screws 17 and 29 would have to be loosened.

It is also provided that the only pivotally mounted link 6 of the opening device 50 with its second joint 3 ″ can be connected to the wing-side retaining rail 52 to a limited extent so that, if necessary, the sealing pressure between the wing 2 and the frame 1 when the frame is closed Window or closed French door can be varied appropriately. To form the joint 3 ″, an eccentric pin 53 is therefore used, which is connected to the handlebar 6 so that it is difficult to turn, e.g. is connected to this at 54 by caulking or riveting. This eccentric pin 53 releasably engages with its shaft 55 in a bearing bush 56, which in turn is rotatably received in the cavity 57 of the holding rail 52.

The eccentric pin has beneath the bearing bush 56
53 a collar 58, which is provided on its circumference with tool engagement surfaces 58 ', for example for an open-end wrench. With the help of the open-ended spanner, a sensitive shift of the eccentricity of the eccentric pin 53 on the handlebar 6 can be carried out and the pressure of the wing 2 against the frame 1 can be regulated in a corresponding manner.

When the eccentric pin 53 is actuated for the purpose of transverse adjustment of the holding rail 52 and thus wing 2, a longitudinal displacement of the holding rail 52 with the wing also occurs due to the eccentricity. This inherently undesirable wing displacement can, however, be easily compensated for with the aid of the eccentric 39 acting on the bearing rail 51.

The display device 50 also has other important training features.

The measures shown in FIGS. 4 to 7 are particularly important. Thereafter, the sliding joint 4 '/ 8' is guided on the bearing rail 51 with a slide 59 which consists of a wear-resistant and unbreakable material and in which the pivot pin 4 'is mounted. The slider 59 is stably guided with a substantially rectangular foot portion 60 within the downwardly open free U-cross section of the bearing rail 51, namely between longitudinal webs 51 'of the same, while it has a neck portion 61 which has lateral flats 61' in the Longitudinal slot 8 'of the bearing rail 51 protrudes. At one end, the slider 59 carries a locking lug 67, which in the closed or rest position of the handlebars 6 and 7, that is to say when this cover position has one another as well as with the bearing rail 51 and the holding rail 52, engages in a fixed locking engagement 68 with little play , as clearly shown in Fig. 5 of the drawing. The latch engagement 68 is located either on the bearing rail 51 itself or on a base 69, with which the bearing rail 51 can be coupled in a similar manner as is the case according to DE-GM 89 12 421.

The locking lug 67 is preferably formed by a flat nose protruding rearward from the slider 59, which can move into a claw 70 of the locking engagement 68 practically without side play. Inlet bevels 71 or rounded corners on the nose and / or in the claw serve the purpose of ensuring a proper entry of the locking projection 67 into the locking engagement 68.

It can also be seen from FIGS. 5 and 6 of the drawing that the end 72 of the slide piece 59 facing away from the locking projection 67 has a greater distance from the joint 4 'than the free end of the nose forming the locking projection 67. Since the slider 59 finds its abutment with its end 72 on the longitudinal webs 51 'of the bearing rail, the possibility is counteracted that the locking projection 67 executes a sideways deflection movement when it enters the locking engagement 68. The hinge 4 'of the handlebar 7 is clamped in the sliding slot 8' without play via the latch shoulder 67 retracted into the latch engagement 68, so that the closing pressure forces exerted on the wing 2 by the latch devices also improve in the area of the opening devices 50 to bring about an improvement Allow gasket pressure to be used for the sash 2 on the fixed frame 1.
