Description

The invention relates to a latch fitting according to the preamble of claim 1.

Such operating handles for doors, windows or the like. generally have two assemblies on, namely a rosette body for axially fixed / rotatable mounting a Handle on a door or window sash and one arranged on the door or window frame Lock box. The latter has an opening for receiving one with the handle gear-connected locking element that is longitudinally displaceable and in the rosette body can be fixed for locking on a holding surface in the lock case.

Examples of such technology include GB 2 177 452 A and US 4 063 763 A described. The locking elements are firmly attached to a rail an undercut of a counter rail is performed. This generally requires elaborate Long elements and their inclusion in profiles or cutouts to be made by the carpenter. There are a number of fastening screws at each locking point necessary to hold the relatively wide rosette body securely. Is the frame narrow, the lock box must be embedded in it to match the width of the Rosette body still offer space. Overall, for full function is high Precision of the preparatory work is necessary, but not always in practice is guaranteed. Uncontrolled large tensile and compressive forces can affect sheet metal parts strong deformations occur during use, which make the bolt fitting unsuitable do.

It is an important goal of the invention to be as simple and economical as possible Remedies to remedy the situation and to develop an improved bolt fitting that can be reliably installed with little installation effort. It is also aimed at high break-out security with a compact design, i.e. minimum dimensions.

Main features of the invention are set out in the characterizing part of claim 1. Independent designs are the subject of claims 7, 13 and 15. Developments are defined in claims 2 to 6, 8 to 12, 14, 16 and 17.

With a bolt fitting for doors, windows or the like, with a rosette body, the a screw-on surface, e.g. a door or window sash can be attached with one Handle which is mounted axially fixed / rotatable on the rosette body with a handle neck, and with a closing part arranged on the door or window frame side, through which Actuation of the handle, a locking element can be fixed, for example a mushroom bolt, Hook or the like, which for locking holding surfaces in the closing part at least in sections engages behind, the invention provides according to claim 1 that the Locking element is a screw bolt projecting transversely on the handle neck, with a Flange head can be inserted into a locking groove of the locking part and in two to each other angular directions can be jammed.

This construction offers a number of remarkable advantages. First, it enables Arrangement of the locking element on the handle neck, a narrow shape of the rosette too realize that themselves do not accommodate a locking piece and also no gear elements got to. As a result, the screw points can be centered in the rosette body accommodate what not only increases the strength of the assembly, but also their Duration greatly shortened. A few screw connections are sufficient for reliable Fastening that also does not require any cumbersome preliminary work. Especially are convenient to use and the fact that the bolt fitting with its very simple clamping mechanism withstands high tensile and compressive loads Duration withstands. In the locked state, a rich pressure is guaranteed because the locking bolt is clamped in different directions, namely at an acute angle into the depth of the lock case and at the same time slightly upwards a crossbar route, the course of which with the means specified in claim 10 to 12 is adjustable.

According to claim 2, the locking bolt is in a radial stepped bore of an insert screwable, which sits non-rotatably in the handle neck and be a steel body according to claim 3 can, on the one hand the handle neck and on the other hand the components of the rosette body are attached. This makes assembly even easier.

If the handle neck according to claim 4 has a transverse hole through which the Locking bolt on a driver insert coaxial to the axis of rotation of the handle neck can be fastened, the axially fixed / rotatable mounting of the handle neck and rosette body in accordance with claim 5 expediently by means of an axially engaging in the insert Bottom screw takes place, one achieves a double bracing of the insert in mutually angular directions. This leads to particularly high usability the bolt fitting.

According to claim 6, the insert is held in a form-fitting manner, which is a Guide bushing of the rosette body penetrates, being in this as well as in the Elements located to limit the rotation of the handle in selected angular positions are present, e.g. Attacks laying down in an open and a Closed position for the door or window sash. In an extremely space-saving arrangement can also provide locking elements, thanks to which the handle, for example, in Turn and tilt positions can be felt snapped into place.

For the important construction of claim 7, according to which the locking groove is generally hat or is bell-shaped and on or opposite a widened inlet part has a sliding surface for the bolt head, namely an inlet slope independent protection claimed. The special groove shape makes it particularly possible easy to swivel the locking bolt into the locking part recess or at the Uncouple unlocking, to which the sliding surfaces contribute effectively.

The locking groove is expedient according to claim 8 to the screwing level with ramps provided, which the inserted bolt head engages behind, which makes it easy to operate a stable locking is effected. This is done by training Claim 9 supports, after which the locking groove in the box-shaped closing part is arranged eccentrically, preferably near an outer wall and so that it with a catch curve ends approximately in the middle of the locking part. The thereby possible extremely narrow rosette bodies save it from having the lock box in the conventional way to have to let in the door or window frame.

Inside the locking part, the locking groove according to claim 10 in a pocket pass over an adjustment plate, leaf spring or the like. records which according to claim 11 extends into a chamber on an ascending bolt section which is - the bolt groove continuing in depth from the inlet slope - to the catch curve connects and offers space for a distance adjustment, preferably according to claim 12 by changing the position and / or shape of the leaf spring or adjusting plate an adjusting screw acting on it in the area of the chamber from the locking section. This allows adjustments to local conditions in a simple manner.

Independent protection is also claimed for the feature of claim 13, according to which in the handle neck parallel to its axis of rotation, a recess for receiving a Child lock, a lock cylinder or the like. is present so that the handle against unauthorized actuation can be secured, advantageously in a manner known per se according to claim 14, characterized in that a locking bolt for locking the handle in assigned holes of rosette body components can be advanced.

Yet another design is characterized by this from that at least one additional locking element on the handle neck at a distance from the locking bolt is present, which means at least one opening position of the door or window sash e.g. can hold for night ventilation. One is essentially suitable Grip head projection running parallel to the locking bolt according to claim 16 or an insertable into the locking groove, preferably rounded nose according to claim 17. A pair of such, possibly offset from one another, is also possible Projections so that two clickable opening positions are available.

This preferably has a hexagonal shape with a radial direction Stepped bore 32, which has an inner threaded portion 34. You add that Insert 30 in the handle neck 18 so that its stepped bore 32 with a transverse hole 28 of the handle neck is aligned. Now becomes a locking bolt 40, on its shaft 42 Threaded section 44 connects terminally, through the transverse hole 28 in the stepped bore 32 of the insert 30 screwed in, the latter is radially in the handle neck 18 or secured across. The bolt 40 has on its head for screwing in and out 46 a recess 48 for the positive engagement of a tool.

When assembling components, a compression spring 50 and a of which, resilient cover plate 52 is slipped close to the circumference of a center hole 54. He is positively fitted into a socket 70 provided with an inner polygon 72, as soon as it is inserted through a guide bushing 64 which is centered on one Rosette body 60 is provided and is preferably in one piece with it. The socket 70 has a collar 74 with e.g. two protrusions 76 diametrically opposed to each other and interact with arcuate recesses at the bottom of the rosette 60, which have rotation-limiting lugs 78 (FIG. 3; FIGS. 4a, 4b). A e.g. out Plastic base plate (not shown) can be the underside of the rosette enclose in a frame shape, for example around damaged areas, existing screw holes or the like. to cover on the mounting surface.

The rosette body 60 has two screw holes 68 for attachment to one (not shown) door or window sash and further on the narrow ends each a trough 62 (Fig. 1) to the cover plate 52 against the force of the Lift spring 50 and can pivot. In one cover position there is a Locking hole 56 the passage of the locking bolt 26 to locking holes 66 of the Rosette body 60 free; in the opposite position of the cover plate 52, it locks that the locking bolt 26 cannot pass through.

The fully assembled handle assembly is axially fixed / rotatable by a floor screw 38 held together, which also has a plug-in opening 58 for a screw head Tool and with its screw shank into an axial thread (indicated in Fig. 1 center) 36 of the insert 30 engages. A flare connection would also be possible.

For attachment to the (not shown) frame of a door or window is a Lock box 80 is provided, the screwing level 90 transverse to that of the Rosette body 60 extends. The closing part 80 has one near an outer wall 82 eccentrically arranged locking groove 84, which is approximately bell-shaped or hat-shaped and from a widened end section 85 into a narrower body 106 a catch curve 105 merges, which is approximately in the upper center of the lock box 80 is located (Fig. 2b).

The massive, e.g. Body of the closing part made of steel or die-cast zinc 80 is provided with weight-saving recesses on the bottom. He has three to each other and with respect to the center of the box, screw holes arranged at a wide angle 92 (Fig. 2a, 2b; Fig. 3). This is a high-strength three-point screw with ensures a secure system of level 90 of the locking part 80 on the frame wall.

Next to a screw hole 92 there is an inlet slope near a narrow end 100 (FIG. 2b), which is approximately in the longitudinal center of the widened end section 85 the locking groove 84 begins and aims at its depth. At least approximated in parallel the initial parts of two ramps 102, 104 (FIGS. 2a, 2b; FIG. 3; FIG. 1) run the continue as crossbars along the narrower main part 106. The lower one Ramp 104 forms a stop in the depth direction of the closing part 80 for e.g. as Leaf spring formed adjustment plate 94, which can be inserted into a pocket 88 and along an increasing locking distance 89 extends into a chamber 86 which the locking groove 84 continues beyond the catch curve 105 inside. On the side of the closing part 80, which is opposite the outer wall 82 is a threaded hole 96 for receiving a Set screw 98 is present, which, as an adjusting screw, is particularly elastic Deformation of the adjustment plate 94 allows. The associated end can then be in evade chamber 86 and tighten the locking of the bolt head.

The locking bolt 40 has a flange or locking head 46 such that it when pivoting the handle 12 from its open position (Fig. 4a) into the inlet section 85 along the slope 100 of the closing part 80 is insertable and in its Locking position (Fig. 4b) the ramps or locking bars 102, 104 under contact engages behind force-absorbing curve 105. This relatively large-scale support ensures a stable locking high security against break-ins, so that a Prying out the latch is effectively prevented. It also suppresses the adjustable Plate 94 a rattling game of the head flange 46 in the locking groove 84.

The invention is not restricted to one of the above-described embodiments, but can be modified in many ways. An aesthetic advantage is that it is preferred cranked handle main part 16 in the locking position the course of the Door or window sash follows, e.g. is aligned parallel to it, while conventional Bolt fittings inevitably a disturbing inclination of the handle inevitable is. A preferred design of a bolt fitting 10 for doors, windows or the like. has a rosette body 60 for axially fixed / rotatable mounting of a handle 12 and a locking part 80 which can be fastened on the door or window frame side, to which by Actuation of the handle 12, a locking element 40 can be fixed, namely one on the handle neck 18 transversely protruding bolt 40. Its flange head 46 can slide into a The locking groove 84 of the locking part 80 engages, in which it extends at an angle to one another Directions jammed widespread. The locking bolt 40 is held on an in Handle neck 18 non-rotatably seated insert 30 on which the rosette body 60 by means of a axially engaging bottom screw 38 is attached. The e.g. bell-shaped locking groove 84 has 85 sliding surfaces on a widened inlet part, namely one Entry slope 100 and ramps 102, 104, which are the easily inserted bolt head 46 engages behind.
