Description

The invention relates to a hooking device between the wing and the fixed frame of windows, doors or the like. Which are equipped at least for locking purposes with an espagnolette fitting, which on the one hand has fixed locking pieces, for. B. on the fixed frame, and on the other hand by locking rods adjustable bolt nocks or the like, for example on the wing, wherein at least between those spars or legs of the wing and fixed frame locking pieces and locking rods adjustable by driving rods or the like are provided which are opposite the spars or legs connected or connectable by hinges or joints.

In the case of windows and doors or the like with wings that can be opened and closed about a laterally perpendicular axis - the so-called rotating wings - the fixed locking pieces are regularly provided at least on the upright frame spar that is opposite the upright frame spar that carries the hinges or joints. The associated locking cams or the like which can be adjusted by connecting rods are then installed on the adjacent wing spar.

In the case of windows with wings that can be tilted about a lower, horizontal axis or that can be folded about an upper, horizontal axis, the fixed locking pieces are accordingly located on the upper or lower horizontal frame spar, while the locking cams or the like adjustable by the drive rods are on the associated upper or lower wing spar are provided.

Of course, in all cases there is also the possibility of arranging fixed locking pieces and locking nocks or the like which can be adjusted by drive rods, and also between those frame and wing spars which each extend at right angles to the frame and wing spars equipped with the hinges or joints. In this case, the connecting rod fitting for adjusting the locking cams or the like also includes several connecting rods which can be displaced at right angles to one another and which are coupled to one another by so-called corner deflections, so that they can be adjusted simultaneously by a common operating handle.

In the case of windows, doors or the like with a tilt-and-turn sash, it generally proves to be expedient or even necessary to provide stationary locking pieces and locking cams or the like that can be adjusted by drive rods, which are then in the locked switch position between all frame and wing spars The espagnolette fittings are mutually interlocking.

The locking pieces and locking cams or the like, which can usually be brought into and out of bolt engagement with one another by espagnolette fittings, are not particularly well suited for achieving an intrusion-resistant locking between the wing and the fixed frame, because their active surfaces when the wing is locked in the closed position are only parallel to the locking plane of the Behind the window, the door or the like. The dimension of this mutual engagement is only a few millimeters, for example between 2 mm and 5 mm.

It is obvious that by attaching a suitable lever tool to the outside of the window, the door or the like. Between the sash and frame there is the possibility of the mutually adjacent spars or legs of sash and / or frame at least in their elastic range to deform by actuating the lever tool so that the effective surfaces of locking pieces and locking cams or the like get out of locking engagement, so that the window, the door or the like is then free for undesired opening.

Therefore, ways have already been taken to counter this lack of the known espagnolette fittings. According to this, special precautions have been taken directly on the locking pieces and locking cams or the like interacting between the fixed frame and sash, which counteract a forced uncoupling of the cooperating engagement surfaces. According to the magazine "Baubeschlag-Magazin", issue 3/1985, page 58 and issue 5/1985, pages 108 and 113, the locking cams adjustable by the drive rods were designed as so-called mushroom pins with a thickened head section and the associated frame-side Provide closure pieces with an approximately C-shaped undercut engagement profile for these mushroom cones. However, the double function of both the locking pieces and the locking cams or the like often leads to installation and functional problems, because in the window and door production the distance between the rebate peripheral surfaces of the sash and the fixed frame varies within larger limits and then the locking pieces and locking cams or cannot work properly in every case.

For sash windows and tilt-and-turn windows, espagnolette fittings are also known, for example from CH-PS 635 398, in which at least two locking slides connected to the espagnolettes are used, which are adjustable in different directions on different sash edges and thereby in their associated, different Corners of the fixed. Frame closure pieces are to be retracted with the least possible play in the sash level, in such a way that in the locking switch position of the connecting rod fitting the sash is optimally closed directly in the area of its corners at the associated corners of the fixed frame and is thus blocked against prying out.

In this case, too, the locking slide adjustable by the drive rods yet another double function, namely, on the one hand, they effect the locking of the wing lying in the closed position on the fixed frame and, on the other hand, bring about the burglar-resistant holding connection between the wing and the fixed frame. CH-PS 635 398 is basically similar to connecting rod fittings for doors and windows with a hinged folding leaf, on the one hand, and for doors and windows with a tilt-and-turn leaf, on the other hand, but is also already known from FR-PS 1 081 674 and the associated add-on FR-PS 67 427 or from NO-PS 131 096 and DK-AS 147 455.

In DE-A-20 35 026 (Fig. 2) tilt locking parts of a tilt and turn window are disclosed, which only interlock behind each other when the associated connecting rod fitting has been brought into its tilt switch position. In this tilt switch position, however, the locking pins of the wing provided on the connecting rod fitting are disengaged from the associated locking brackets on the fixed frame, because otherwise the wing cannot be moved into its tilt opening position relative to the fixed frame.

Since the tilt locking parts must allow the tilting movement of the wing relative to the fixed frame, their mutually facing hook elements have such a configuration that they are at a considerable distance from each other when the wing is in the closed position against the fixed frame. Only in this way is there the possibility that the wing can take the necessary tilt angle to the fixed frame when tilt opening.

However, since the tilt locking parts are not pushed one behind the other in the closed switch position of the espagnolette fitting, but rather, as already mentioned, only in the tilt open switch position of the same, a burglar-resistant locking between the leaf in the closed position and the fixed frame cannot be achieved will.

The invention aims to provide a hooking device between the sash and the fixed frame of windows, doors or the like. Of the type specified at the beginning, in which the burglar-resistant function is separated from the locking function, and therefore the hooking device is either installed or problem-free as required can be omitted.

The set goal is achieved according to the invention by the characterizing features of claim 1, namely in that at least in the corner-length sections between the spars or legs of the wing and the fixed frame substantially transversely to the main plane of the window or door and only slightly Gap spacing interlocking interlocking blocks are arranged,

that the wing-side interlocking blocks only engage behind the frame-side interlocking blocks against the opening direction of the wing, and also under or under, only in the closed switch position of the connecting rod fitting. spread,

and that in each case one of the interlocking blocks is fixedly anchored, while the associated other interlocking block is coupled to the drive rod fitting so as to be displaceable transversely to its direction of engagement.

Locking pieces and locking cams or the like, which are used only for locking purposes, can then be formed in the usual way and be present on the connecting rod fitting.

According to claim 2 according to the invention provided that wing and frame-side interlocking blocks are arranged in the areas near the corners between two mutually angled spars or legs of the wing and the fixed frame, so that there are effective interlocking interventions at right angles to one another.

According to the invention, a particularly important further training measure is considered

that - according to claim 3 - the behavior surfaces of the interlocking blocks are each inclined in the same direction against the plane of the sash and the fixed frame,

and that the inclined position of the cooperating interlocking surfaces is provided away from the sash rebate peripheral surface towards the frame rebate circumferential surface and at the same time in the direction of the opening side - inside - of the sash. If, in this case, an attempt is made to place a lever tool in the outer sealing gap between the wing and the fixed frame, then the interaction of the interlocking interlocking surfaces results in a force component which forces the spars or legs of the wing and fixed frame in the direction of the closure plane tries to deform towards each other. The desired interlocking effect is then necessarily increased.

So that the interlocking device cannot be rendered ineffective by drilling, it has been found that, according to claim 4, the longitudinal surfaces of the interlocking blocks facing away from the opening side - inside - of the window, the door or the like are each inclined towards the window or door plane or have arched installation position and there at least with a layer or support made of drill-resistant material, eg. B. hardened steel, glass, ceramics or the like. Are provided. A drill striking these longitudinal surfaces is deflected in the direction transverse to its longitudinal axis by the measures in question and therefore breaks before it can penetrate the material of the interlocking blocks.

In order not to impair a practical smooth movement of the connecting rod fitting by the hooking device, it proves to be advantageous if, according to claim 5, the hooking surfaces of the cooperating hooking blocks are spaced apart from one another have, but which is dimensioned much smaller than their mutual surface coverage. The arrangement is preferably such that the ratio of the gap distance to the surface coverage is approximately 1: 4 and the depth of the interlocking engagement is at least equal to the gap distance.

A hooking device for windows, doors or the like, whose wing and frame spars or legs consist of metal profiles that have undercut grooves or channels for holding fittings, according to claim 6, characterized in that the hooking blocks each have undercut foot parts which match the undercut grooves or channels in their profile cross-section and that the drive rods of the drive rod fitting are provided with edge catches adapted to the edges of the associated hooking blocks.

In the drawing, the subject matter of the invention is shown in exemplary embodiments. It shows

• 1 shows, in a schematically simplified view, a window in which a conventional connecting rod fitting and additional hooking devices are provided between the peripheral circumferential surfaces of the fixed frame and the sash,
• 2 is a section on a larger scale along the line II- in Fig. 1,
• Fig. 3 is a section corresponding to FIG. 2 through a structural variant of the hooking device and
• Fig. 4 shows a portion of a drive rod of the drive rod fitting in the installation area of a hooking device.

In Fig. 1 of the drawing, a window 1 is shown, the fixed frame 2 and the wing 3 of which are indicated only by the fold circumferential surfaces opposite one another in the direction transverse to the closure plane at a distance of 4 - that is to say purely schematically.

Within the clearance area 4 - the so-called rebate air - between the rebate peripheral surfaces 2b and 3a of the fixed frame 2 and sash 3, the drive rod fitting 5, which is used at least for locking purposes, is accommodated. This drive rod fitting 5 is installed in the embodiment of FIG. 1 in the area of all four spars or legs between the fixed frame 2 and the wing 3. It consists of drive rods 6, which are displaceably guided on the wing 3 in the longitudinal direction of the respective wing spar, for the movement of locking cams 7 or the like, and of the locking cams 7 on the fixed frame 2, associated with locking pieces 8.

The drive rods 6, which can be moved at right angles to one another on the various spars or legs of the wing 3, are each connected to one another by a corner drive 9, so that they can be moved together and to the same extent. Through the drive rods 6, the locking lugs 7 or the like can be brought into and out of locking engagement with the locking pieces 8, so that the wing 3 on the fixed frame 2 is either fixed in its closed position or relatively to existing - but not shown - Hinges or joints can be moved in the open position.

In Fig. 1 of the drawing, the connecting rod fitting 5 is shown in its unlocking switching position, ie the wing-side locking cams 7 are out of engagement with the frame-side locking pieces 8. In the spacing area 4 between the fold peripheral surfaces 2b and 3a of the fixed frame 2 and wing 3 - that is within the existing air gap - a larger number of hooking devices 10 are assigned to the window 1.

For example, four hooking devices 10 are provided between the left, upright bars of the fixed frame 2 and the wing 3, while there are three such hooking devices 10 between the right, upright bars thereof.

There are also three hooking devices 10 between the lower horizontal bars of the fixed frame 2 and sash 3, while in the area of the upper horizontal bars or legs there are in turn two hooking devices 10.

It proves to be particularly advantageous if two hooking devices 10 are arranged in the corners of fixed frame 2 and wing 3 near the corners between two mutually angled spars or legs thereof and there at the same time in two mutually perpendicular, but parallel to the plane of the closure Window or the directions of the door 1 are effective.

Each individual interlocking device 10 consists of two interlocking blocks 11 and 12, the interlocking block 11 in each case being fixed in place on the fixed frame 2, while the associated interlocking block 12 is displaceably guided on the wing 3, namely with the connecting rods 6 of the connecting rod fitting 5.

When the connecting rod fitting 5 is brought into the locked switch position, the two interlocking blocks 11 and 12 of each interlocking device 10 are interlocked with one another, while in all other switching positions of the connecting rod fitting 5, which enable the wing 3 to be opened relative to the fixed frame 2, they are put together without interlocking engagement .

In Fig. 2 of the drawing, a possible design for the hooking devices 10 is shown in cross-section on a larger scale, namely on a window or a door 1 in which both the spars or legs of the fixed frame 2 and those of the wing 3 consist of metal profiles. In the fold peripheral surfaces 2b of the fixed frame 2nd are undercut profile grooves 13 running in the longitudinal direction and a similar undercut profile groove 14 also runs along the rebate peripheral surface 3a of the spars or legs of the wing 3. In the undercut profile grooves 14 on the rebate peripheral surfaces 3a of the wing 3 there are the drive rods 6 of the drive rod fitting 5 led. The corner deflections 9 of the drive rod fitting 5 can also be properly fixed in these undercut profile grooves 14 on the wing 3.

The interlocking block 11 of the interlocking device 10 according to FIG. 2 has an undercut foot part 15, which can be inserted substantially suitably in the longitudinal direction into the undercut profile groove 13 of the spars or legs of the fixed frame 2, whereby it is, for example, by a grub screw 16 can be set within the undercut profile groove 13 at any desired location.

The section 17 of the interlocking block 11 protruding from the foot part 15 and protruding from the opening gap of the undercut profile groove 13 is provided with an interlocking surface 18 which has an installation position facing away from the opening side of the window or door 1, and also against the installation plane of the fixed one Frame 2 takes an inclined position. The inclined position of the interlocking surface 18 on the interlocking block 11 is such that it runs away from the circumferential surface of the fold of the fixed frame 2 and also from the opening side thereof. Their distance from the room-side visible surface 2a of the fixed frame 2 thus increases proportionally with their distance from the fold peripheral surface 2b of the fixed frame 2.

The interlocking block 12 located on the wing 3 is also equipped with foot parts 19 which fit in a form-fitting manner in the undercut profile groove 14 on the circumferential groove surface 3a of the wing 3 and can be inserted into the longitudinal direction thereof. The foot parts 19 of the interlocking block 12 are, however, designed such that they engage in the region of edge-side catch notches 20 of the drive rod 6 and can include a central web 21 which remains between them (FIG. 4).

Also in the case of the interlocking block 12, an extension section 22 adjoins the foot parts 19, which comes to lie outside the opening gap of the undercut profile groove 14 of the wing 3 and next to the fold peripheral surface 3a thereof. When viewed from the opening side of the window or door 1, section 22 of interlocking block 12 is located in an area that lies behind section 17 of interlocking block 11 on the frame.

The interlocking surface 23 of the interlocking block 12 facing the interlocking surface 18 on the interlocking block 11 also has a position inclined to the locking plane of the window or the door 1, namely that its plane extends parallel to the plane of the interlocking surface 18, but at the same time from the same occupies a slight gap distance 24.

The interlocking surfaces 18 and 23 of the two interlocking blocks 11 and 12 have, in the correct installation position relative to one another, a surface coverage 25 which corresponds to a multiple of the gap distance 24, preferably approximately four times the same.

The angle of inclination of the interlocking surfaces 18 and 23 against the locking plane of the window or door 1 should be at least 15 °, but preferably between 15 ° and 45 °.

In practice, the gap distance 24 between the two interlocking surfaces 18 and 23 of the interlocking blocks 11 and 12 need only be dimensioned so large that, in the normal closed position of the wing 3 on the fixed frame 2, the interlocking surfaces 18 and 23 when the drive rod fitting 5 is actuated allow this to move past each other freely. At the most, this gap distance 24 should therefore be 1 mm, so that it is ensured that in the operative position of the hooking device 10 the hooking surfaces 18 and 23 of the two hooking blocks 11 and 12 are already at a slight relative bending of the wing spars or - Legs against the frame bars or legs come into support contact with each other. Already the attempt to introduce a lever tool between the mutual outer contact surfaces 2c and 3c of the fixed frame 2 and sash 3 then leads to the interlocking surfaces 18 and 23 pressing against one another and thereby producing a force component which the respective spars or legs of fixed Frame 2 and sash 3 seeks to move parallel to the closure plane or transversely to the fold peripheral surfaces 2b and 3a.

Prying apart the claw-like interlocking blocks 11 and 12 transversely to the main plane of the window or door 1 and consequently prying apart the locking pieces 8 and locking cams 7 or the like of the connecting rod fitting 5 is thereby effectively prevented.

FIG. 3 of the drawing shows an embodiment variant of a hooking device, which is advantageously developed over that of FIG. 2. There are namely the interlocking surfaces 18 and 23 of the two interlocking blocks 11 and 12 after the opening or. Inside of the window or the door 1 facing away - ie the outside - shielded by upstream longitudinal surfaces 26 and 27, one against the window or. Door plane inclined or arched installation position and at least one layer or support 28 or 29 made of drilling-resistant material, for. B. hardened steel, glass, ceramics or the like. Wear.

Already the inclination or curvature of the surfaces 26 and 27 deflects a drill hitting it with the tip so transversely to its longitudinal axis that the resulting bending stresses lead to its breakage. In addition, the coatings or Aufla gene 28 and 29 but also effectively prevents the penetration of the drill tip into the material of the interlocking blocks 11 and 12.

Since it is not visible from the outside in the closed position of the window or door 1 at which points between the wing 3 and the fixed frame 2 the hooking devices 10 are located, it is otherwise relatively difficult to obtain direct access to them. The large number of interlocking devices 10 that can be provided thus considerably increases the burglar-resistant effect of the windows and doors equipped therewith.
