Description

The invention relates to a window, a door or the like. In which or at least the sash frame is composed of metal or plastic profiles which have on their folded surface an open on one side but undercut on both sides in the cross-sectional direction profiled guide channel for the longitudinally slidable receiving a drive rod , wherein the drive rod located in the guide channel can be coupled from the open side of the same with an actuating gear, which is mounted in a housing and can be driven in rotation by an operating handle, for. B. a pinion, wherein the housing of the actuating gear is supported in front of the open side of the guide channel on the metal or plastic profile and can be fastened to it, for example by screwing, furthermore the operating handle with a polygonal mandrel, for example a square or hexagonal mandrel, from the room-side end face of the casement frame through a hole in the metal or plastic profile in a correspondingly profiled driver recess of the drive member is positively engaged and is held in engagement by means of screw.

A window, a door or the like of this type is known from EP-A-0 283 659. So that only one installation space is required for the actuating gear of the drive rod fitting in front of the undercut profiled guide channel pointing fold surface of the sash frame, as is the case with the conventional one Profile design with a dimension of about 10 mm is readily available, according to this prior art, at least the metal or plastic profile of the casement in the installation area of the actuating gear is provided with an opening that penetrates the bottom of the guide channel in the metal or plastic profile and through which the drive member (pinion) bearing section of the actuating gear is penetrated. Only a housing section of the actuating gearbox, which receives or guides at least the ends of a clutch slide that is in permanent engagement with the drive member (pinion), is supported on the metal or plastic profile in front of the open side of the guide channel.

In order to ensure that the espagnolette fitting functions properly in the long term, according to EP-A-0 283 659 the length of the clutch slide is dimensioned at least by its maximum travel distance longer than the length of the opening in the bottom of the guide channel on the metal or plastic profile and the clutch slide is attached to both ends provided to the rear facing, from a slot opening in the housing section of the actuating gear which protrudes it, driver lugs which can be inserted into suitable driver recesses on the drive rod. In addition, the housing section of the actuating gear which supports the drive member (pinion) is provided with an engagement thread for fastening screws on a plane parallel to the direction of movement of the clutch slide and passing through the axis of rotation of the drive member (pinion) at least on one side, but preferably on both sides, of the drive member (pinion) also reach through a bearing rosette for the operating handle that is supported on the end face of the casement on the room side.

According to EP-A-0 283 659, however, it is also already known to connect threaded bushes designed as so-called rivet nuts for engaging the fastening screws for the bearing rosette of the operating handle directly to the sash frame and to connect the housing of the actuating gear in its functional position with the aid of crossover and undergrip bars as well as a clamping screw against an undercut area of the guide channel to prevent jamming and shifting.

According to the state of the art corresponding to EP-A-0 283 659, however, there are still certain technical shortcomings when the undercut profiled guide channel of the metal or plastic profiles and the housing of the actuating gear for the connecting rod fitting are not exactly coordinated with one another with regard to the installation criteria.

Apart from the fact that the installation of the actuating gear in the casement profile is then made more difficult, it can also happen that the seat of the same on the casement loosens after a relatively short time in practical use and thereby at least complicates the operation of the connecting rod fitting.

The object of the invention is to provide a window, a door or the like. With espagnolette fitting of the generic type, in which the stop or installation of the actuating gear for the espagnolette fitting on the casement is simplified and, moreover, the proper fit of the actuating gear on the casement in practice Long-term use can also be guaranteed if the installation dimensions on the metal or plastic profile and on the housing of the actuating gear are not exactly coordinated.

According to the invention, this object is basically achieved by the characterizing features of claim 1, namely by
that in the housing portion receiving the ends of the clutch slide at least one rotary toggle is mounted with an axis parallel to the main plane of the drive element,
that the rotary toggle on the one hand has a tool engagement accessible through the end wall of the housing section, and on the other hand carries at least one nose or tongue, the top of which is spaced from the rear longitudinal edges of the housing section, and that the nose or tongue in a rotary position of the rotary knob from a recess in the housing section supporting the pinion is received flush,
while in its other rotational position, projecting beyond the side faces of this housing section, it is pivoted into the undercut region of the guide channel on the metal or plastic profile of the casement.

In this embodiment according to the invention, it is possible to simply insert the actuating gear of the connecting rod fitting in the area of the opening in the direction parallel to the sash plane into the metal or plastic profile and then to determine its fastening position simply by moving the rotary knob from its rest position into the fastening position.

If the surfaces in operative connection with the undercut areas of the guide channel on the metal or plastic profile are in a wedge-shaped position with respect to the plane of rotation of the rotary knob and in the direction of rotation, a tensioning fixing of the actuating gear on the metal or plastic profile can be brought about with the help of the rotary knob alone .

According to the further developing feature of claim 2, the rotary toggle lies with its axis of rotation on the longitudinal central plane in the housing of the actuating gear and carries two diametrically opposite circumferential areas from its rear axially parallel arms, each of which has a nose or at its free end Tongue is provided, which is approximately tangential to the rotary knob circumference.

By actuating the rotary knob, the actuating gear on the metal or plastic profile, which is symmetrical with respect to the longitudinal center plane of the housing, can be brought about in this way.

According to the feature of claim 3 according to the invention, the rotary toggle has a circularly delimited disk which is held within the housing section receiving the ends of the coupling slide between its end wall and the toothed section of the coupling slide, the arms of the rotary toggle bearing the lugs or tongues laterally on the longitudinal edges of the clutch slide are passed.

These measures achieve a stable design and secure mounting of the rotary toggle.

Another inventive feature is according to claim 4 but also that the housing section containing the clutch slide carries sideways projecting flanges in which there are at least approximately threads aligned transversely to the rotary plane of the rotary knob, in which in turn there are clamping screws which cut against the outer end faces of the undercut profiled guide channel are braced.

It is particularly advantageous if the free ends of the lugs or tongues are approximately opposite in their operative position to the clamping screws within the undercut profiled guide channel.

According to claim 6, a feature of the invention is also seen in the fact that the angle of rotation range of the rotary knob is limited to approximately 45 °.

According to claim 7, the invention also provides that guide holes for the fastening screws are formed on both sides of the drive member and axially parallel to it in the housing section of the actuating gear containing the drive member, via which the bearing rose of the operating handle can be fastened to the metal or plastic profile of the casement. If these guide holes are closely matched to the nominal size of the fastening screws, the operative connection between the operating handle and the actuating gear can be optimized by the engagement of the fastening screws in these guide holes.

In the drawing, the subject of the invention is shown as an embodiment. It shows

• 1 is a fragmentary longitudinal section of the casement of a window, a door or the like. With the actuating gear inserted therein on a larger scale,
• Fig. 2 is a partial view of the casement and the actuating gear in the direction of arrow II of FIGS. 1 and
• 3 shows a partial section along the line III-III through the casement and the actuating gear according to FIG. 1.

Of a window, a door or the like, which usually consists of a fixed frame and a casement, only a cutout area of the casement 1 can be seen in the drawing. This casement 1 is composed of metal or plastic profiles that are produced by extrusion or extrusion. Light metal profiles are preferably used for the production of the sash frame 1, which have a rollover 2 directed parallel to the sash plane, to which a fold section 3 adjoins - essentially at a right angle. This fold section 3 is formed by a profile wall, on the outside, the so-called fold surface 4, of a guide channel 5 which is open on one side but undercut on both sides in the cross-sectional direction is provided. This guide channel 5 is delimited on both sides by a hook web 6, for example an L-shaped or angled profile, in such a way that the two hook webs 6 with their free hook legs face each other and limit an open longitudinal gap 7 of the guide channel 5, as is particularly clearly shown in FIG. 2 and 3 can be removed.

On the inside, the guide channel 5 is delimited by a base 8, which forms a part of the fold section 3 on the casement 1. In this guide channel 5 drive rods 9 can be inserted in the longitudinal direction on the casement 1, as can be seen in Fig. 1.

An actuating gear 10 is assigned to the casement 1 and the drive rods 9 which are accommodated in its guide channel 5 so as to be longitudinally movable, the structure of which can essentially be seen in FIG. 1.

In addition, an operating handle with a bearing rosette is assigned to the casement 1 and the actuating gear 10 built into it, but these are not shown in the drawing because they have a known design.

The bearing rosette of the operating handle is connected to the sash frame 1 by screws, in that these screws come into operative connection with so-called rivet nuts, which are rotatably inserted at least into the end wall of the metal or plastic profile on the room side and are overlapped or covered by the bearing rosette of the operating handle .

The actuating gear 10 has a gear housing 13 which has a housing section 15 which supports a rotatable drive member, for example a pinion 14, and an adjoining housing section 16 in which a clutch slide 17 which meshes with the pinion 14 is guided in a longitudinally movable manner.

In the direction of movement of the coupling slide 17, the housing section 16 guiding this extends beyond the housing section 15 supporting the pinion 14 by a considerable amount on opposite sides and forms an extension arm 16a and 16b there, as can be clearly seen in FIG. 1.

The end section 17a leads in the boom 16a and the end section 17b of the clutch slide 17 in the boom 16b, while the middle section 17c thereof is set back relative to the middle housing section 16c toward the housing section 15, as is clear from FIG. 1. For this purpose, the end sections 17a and 17b each adjoin the middle section 17c, which contains the engagement teeth 19 for the pinion 14, by means of an offset 18a or 18b.

Driver pins 20a and 20b on the rear of the end sections 17a and 17b of the coupling slide 17 protrude from the rear of the brackets 16a and 16b of the housing section 16 and come into engagement with coupling holes 21a and 21b of the drive rod 9 which engage in the undercut guide channel 5 on the sash frame 1 are accommodated.

On the one hand, the housing section 16 of the transmission housing 13 comes to rest with its back surface on the end face adjacent to the open longitudinal gap 7 of the two hook webs 6 which delimit the guide channel 5 (FIGS. 1 and 3), while on the other hand the housing section 15 supporting the pinion 14 has a notch 22 engages, which is provided in the bottom of the guide channel 5 bottom 8, as can also be seen in FIGS. 1 and 3.

The pinion 14 is supported in the housing section 15 of the gear housing 13 on both sides with a collar 11 which is received by matching bearing stages 12 on the inside of the housing section 15, as can be seen in FIG. 3.

The lateral guidance of the clutch slide 17 is effected in the region of the end sections 17a and 17b in each case by guide surfaces 23a and 23b which are formed laterally in the housing section 16. Guide surfaces 23c, which are present in the transition region between the housing section 16 and the housing section 15 within the transmission housing 13, serve to guide the side of its central section 17c, as can be seen in FIG. 2.

At least one rotary toggle 24 is arranged in the housing section 16 of the transmission housing 13 receiving at least the end sections 17a and 17b of the clutch slide 17, outside the range of motion of the central section 17c of the clutch slide 17 having the engagement teeth 19 for the pinion 14, as shown in FIGS. 1 to 3 the drawing is clearly visible.

This rotary toggle 24 has a circular disk 25, which is accommodated with its circumferential surfaces in a suitable manner in a bearing recess 26 on the inside of the housing section 16. This bearing recess 26 closes directly on the end wall of the housing section 16 at. The disk 25 of the rotary toggle 24 has a tool engagement 27 - for example a hexagon socket - which is accessible through an opening 28 in the end wall of the housing section 16.

The disk 25 of the rotary toggle 24 is received with an axis parallel to the main plane of the pinion 14 in the bearing trough 26, namely on the longitudinal center plane of the housing 13, and has arms 29a and 29b projecting from its rear side in parallel in two circumferential regions lying diametrically opposite one another. Each of these in turn carries at its free end a nose or tongue 30a or 30b which is oriented approximately tangentially to the circumference of the disk 25 of the rotary knob 24, as can be seen from FIG. 2.

The arms 29a and 29b of the rotary knob 24 are arranged on the disk 25 and, moreover, have a cross section such that they pass sideways past the central section 17c of the clutch slide 17 and allow the rotary knob 24 to be rotated angularly in the bearing recess 26 by approximately 45 °.

In one rotational position of the rotary toggle 24, the lugs or tongues 30a and 30b have an alignment lying parallel to the longitudinal edges of the gear housing 13 and can thereby be received flush with the outside of a recess 31a or 31b in the side walls of the housing section 15 supporting the pinion 14 will. It is then possible to use the actuating gear 10 as a whole through the open longitudinal gap 7 of the guide channel 5 and the notch 22 in its base 8 and the sash frame 1, as can be seen in FIGS. 1 and 3.

Since the lugs or tongues 30a and 30b each connect to the free ends of the arms 29a and 29b, they have a position set back with respect to the back surface of the housing section 16 and thus come to the level of the operating gear 10 after insertion Undercut areas of the hook webs 6 delimiting the guide channel 5 to lie as soon as the back surface of the housing section 16 meets the outside of these hook webs 6.

If the rotary toggle 24 is now rotated by 45 ° from its rest position, the lugs or tongues 30a and 30b reach the undercut areas, that is to say under the hook webs 6 of the guide channel 5, as is shown in FIGS. 2 and 3. The rotary toggle 24 thereby causes the actuating gear 10 to be fixed in position on the casement 1 to prevent it from emerging from the opening 22 and the guide channel 5.

In some cases it may be sufficient to use a rotary knob 24 alone to fix the gear housing 10 on the wing 1. However, it would also be conceivable for this purpose to arrange a plurality of rotary toggles 24 distributed over the length of the housing section 16 on the transmission housing 13.

In any case, it may be advisable to design the top and / or bottom of the lugs or tongues 30a and 30b protruding from the arms 29a and 29b tangentially to the circumference of the disk 25, so that when they are screwed into the undercut areas, the guide channel 5 delimiting hook webs 6 sets a clamping effect for fixing the actuating gear 10.

In the embodiment of a window, a door or the like shown in the drawing, however, the rotary toggle 24 is not used for the final fixing of the actuating gear 10 on the wing 1. Rather, it forms with the lugs or tongues 30a seated at the ends of its arms 29a and 29b and 30b only swivel-out and swivel-in abutments for holding the gear housing 13 on the wing 1. However, special clamping screws 32a and 32b are used here for final or fixed tensioning, which can be seen in FIG. 3. 2 has at least the end portions 17a and 17b of the clutch slide 17 leading Ge housing section 16 in the installation region of the rotary knob 24, flanges 33a and 33b projecting laterally and in which there are at least approximately transverse, namely inclined, internal threads 34a and 34b aligned with the plane of rotation of the rotary knob 24, in which the clamping screws 32a and 32b are located.

These clamping screws 32a and 32b preferably have tool engagements which correspond to the tool engagement 27 of the rotary knob 24. They can therefore be tightened and loosened with the same tool (hexagon key) with which the rotary knob 24 can also be brought in and out of engagement. With the aid of the actuating tool, the clamping screws 32a and 32b can be clamped against the outer end faces of the two hook webs delimiting the undercut profiled guide channel 5 after the rotary toggle 24 has previously been brought into the operative position shown in FIGS. 2 and 3. In a simple manner, a permanently secure attachment of the actuating gear 10 to the sash frame 1 is then achieved by the interaction of clamping screws 32a, 32b and rotary toggle 24.

So that a permanently perfect interaction of the operating handle engaging through a square mandrel in the square nut 35 of the pinion 14 with the actuating gear 10 can be ensured, although its bearing rosette is only fixed via its fastening screws in rivet nuts provided on the sash frame 1 in a rotationally fixed manner, it has proven to be expedient to provide the housing section 15 of the gear housing 13 supporting the pinion 14 on both sides of the pinion 14 with axially parallel guide holes 36a and 36b (FIG. 1).

These guide holes 36a and 36b are each spaced from the axis of rotation of the pinion 14 so that they correspond to the distance of the mounting holes in the rosette of the operating handle from the square mandrel of the operating handle. If the fastening screws are dimensioned long enough for the rosette of the operating handle, these can then penetrate into the guide holes 36a and 36b of the gear housing 13 and thereby ensure the mutual alignment of the positions, provided that the guide holes 36a and 36b are closely matched to the nominal diameter of the fastening screws.
