Description

The invention relates to an actuating handle according to the preamble of Claim 1.

Such handles are in use as window and door handles. In their operation an associated device, e.g. a window gear, a lock nut or the like. taken spinning, causing a window, a door and the like. open and close leaves. A clothing, i. a pair of handles, can by a simple plug connection Door leaves of different thickness are set, for example according to DE 77 24 049 U1, which, however, locking means for functional positions not provided are. In contrast, preference is given to fittings with a stop body on which the Handle axially fixed / rotatably mounted and the attachment cam for attachment has on the mounting surface, wherein locking means define certain angular positions of the handle. Conventional turn / tilt fittings have a shutter, a tilt and a Pivoting position, so that the handle relative to a starting position, e.g. below 0 °, 90 ° or 180 ° stands. A suitable handle describes DE 42 31 123 C2, but with his neck is stored directly in the window sash and at least after a long time Use hardly wobble-free sitting.

Lockable or lockable handles offer more security; often they should only be operated by authorized persons. Examples of such handles are in DE 86 24 544 U1 and EP 0 386 651 B1. The constructions generally include one in the Handle arranged closure or locking device, with a bolt in a hole advanced or withdrawn from the stop body to the handle to lock or unlock.

Namely, where the window or door frame little space is available the dimensions of the stopper body - a rosette or a door plate - disturb, often there is still a body covering this cover, e.g. according to DE 197 44 141 C1. The aesthetics are sometimes quite chunky Slings often less satisfactory.

Where there is enough depth on a wing frame, one with a long guide sleeve provided handle according to DE 195 41 214 C2, in the handle neck a compression spring is seated, inserted into a mounting hole. The exactly to be adjusted Sleeve is supported at the inner end only by a locking pin with a pinion locked to a transverse housing and the only force of the compression spring has to absorb. At the pinion engages a falzseitig introduced drive rod, with which can be adjusted to different functional positions. However, it lacks a screw connection on the window profile, so that especially in long-term use a permanent tight fit of the fitting is not guaranteed.

It is an important object of the invention to address these and other disadvantages of the prior art Technique in the most economical way to overcome and a handle to create that without disturbing stop body dimensions on tight Reliably and permanently install space. The construction should be cost-effective be produced and easy to install and high stability in use exhibit.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 20.

In an actuating handle, in particular a window handle, with a handle main body and a handle head, which terminates in a handle neck and a hole for positive locking Receiving a driver polygon, and with a handle neck superimposed main body, which cam for attachment to a stop surface has, e.g. on a window frame, and which with locking means for setting more preferred Gripping positions is provided, the invention provides according to claim 1, that the Basic body in the handle neck axially einspringend enclosed by this and with connected to a locking body or is connectable, which is located in the handle neck interior Locking elements interacts directly. The main body is therefore whole (or at least with its main parts) housed inside the handle neck and as a result, not (or at most with a thin, disk-like edge) under the end of the grip neck visible. It requires no other built-in parts or intermediate elements, to bring about a desired detent, the conventional usually also required larger dimensions. The outer dimensions are according to the invention determined solely by the handle neck, the directly in front of the mounting surface ends. This contributes to pleasing appearance as well as to small footprint. The Handle can therefore easily be mounted on narrow profiles.

In accordance with claim 2, the base body has a central bore, the one of the polygon interspersed, this leading inside the handle neck socket slidably supports and guides. This is a reliable with minimal movement Storage of the handle made. In addition, claim 3 provides that the main body is mounted or guided with an outer seal in the handle neck; that guarantees a secure radial support despite a short bearing or guide length.

To small overall dimensions, it also contributes, if according to claim 4, the main body on the one hand a cam-carrying flange and on the other hand an annular surface has, on which a sliding ring sits. This will be on a component on tightest The functions of secure fastenability and adequately broad management or storage base combined.

Structurally, it is favorable that according to claim 5, the handle neck inside with each other diametrically opposed locking recesses is provided with the locking lugs cooperate against rotation, which with the socket and / or the locking body - If these are separate components - connected or connectable. So is a play-free rotational drive and full torque transmission with very low Effort guaranteed.

The rotation can according to claim 6, a one-piece with the sleeve spring element and according to claim 7, at least two diametrically opposed Webs or double webs with locking lugs having, with the locking elements in the handle neck are engageable. In preferred design are here Bushing and locking body a one-piece, e.g. two-leaf plastic component. As an embodiment, claim 8 provides that the spring element arcuate, radially outwardly projecting and / or directed into the handle neck interior, locking lugs bearing Has webs or double webs. The alternative of claim 9 is that two Pairs of diametrically opposed webs or double webs present are. The anti-twist device 40 may be e.g. have two double spring webs or form a closed, four-leafed ring.

High stability makes the arrangement of claim 10, according to which the polygon of a Dowel bush is enclosed, the remote, applied to the edge surfaces expansion parts has and is slidably mounted with a sleeve part in the socket. On the one hand is thus free rotation, but on the other hand, a dowel-like Axialverankerung secured in the handle neck interior.

With claim 11 protection is claimed, dais the basic body by stirhseitig on a frame, a profile arranged thereon, a gear box or the like. obliquely introduced screws can be fastened. While conventional stopper body a front-side attachment and therefore a not lowerable in principle minimum height condition, this is brought to zero after the invention, because thanks to the Mounting from the front side of the support body - i. a window frame, one Door leaf etc. - you do not need a screw base on the front.

Specifically, claim 12 provides that the cams aligned parallel to the axis of the bore are and have oblique threaded holes, in which the Retractable screws whose ends bring the body to the mounting surface and anchor it. As a result, this attachment holds high stress was standing. To facilitate the assembly contributes that the cams of general are cylindrical basic shape and according to claim 13 remote, with insertion bevels have tipped ends that are easy to insert into prepared holes and yourself There, in particular, can positively support against mating surfaces.

Another important development of the invention according to claim 14 is that that in the handle neck a recess for receiving a locking or locking unit is present, which gives a shut-off or lockable handle version. To is according to claim 15 on the base circumference at least one extension with a cavity present, with a displaceable in the handle neck and a hole passing through it Locking or locking bolt can be brought into engagement. Has the body after Claim 16, two diametrically opposite projections with outward open cavities, so one or the other cavity can accommodate the bolt and the handle can be locked or locked in two positions offset by 180 °. According to claim 17 are on the rotation between the spring bars circumferential recesses present, in which the extensions are clamped, whereby result in high stability and secure locking.

An important development is characterized in accordance with claim 18 by, that in the locked or locked state of the bolt in the handle neck hole and in the associated cavity is guided, so on a relatively long distance, resulting in increased Safety contributes. According to claim 19, the end of the bolt in the lock or lock state with more than half the circumference of the adjacent extension enclosed and in the adjacent recess recess of the handle neck is pressed, achieved by this all-round positive locking a high locking torque, although the radial distance of the bolt from the handle rotation axis because of Overall small size is relatively small.

That the bolt according to claim 20 in the locked or locked state in him receiving guide recesses in shear parallel to its longitudinal axis claimable, eliminates the previously existing in comparable arrangements Risk of shearing the locking bolt now thanks to a large load cross-section, which extends over the entire length of the bolt. The load test proves that a break on the locking bolt does not occur even at high moments.

It can be seen in the exploded views of Fig. 1 and 2, a handle 10 with a Main part 11, to which a grip head 12 connects, which terminates in a handle neck 13. This takes in its interior 14, the other components, namely a locking body 30, which is guided with a bushing 32 in a base body 20, on which a sliding ring 38 causes an outer guide and storage in the handle neck interior 14, and a square 25, which is insertable into a square hole 15 of the handle neck and together is held by a dowel sleeve 45 with the aforementioned components.

The generally rotationally symmetric base body 20 is for clarity in FIG Fig. 3 and Fig. 4 drawn enlarged. He has a flange 22, from the bottom Cam 24 protrude for attachment to a (not shown) stop surface serve. Upstanding from the flange 22 are two diametrically opposed Projections 60 from which not all the way radially to the outside to an annular surface 28th range, on which the slide ring 38 is seated. Inside, the main body 20 has a central bore 26, in which after assembly of the locking body 30 (FIG stepped bushing 32 is slidably mounted with its sleeve part.

The locking body 30 is provided with an anti-rotation 40, namely with a one-piece Spring element, the two diametrically opposed webs 42 with each has a radially outwardly projecting latching lug 44 (see Fig .. 6). Around To achieve particularly large locking force, the spring elements 40 double webs 68 have (Fig. 7).

The handle neck interior 14 has an end annular surface 16 (Fig. 2), to the axially inwardly a concentric re-entrant annular step 17 connects, with the circumferential distances with Detent depressions 18 is provided. These act with the locking lugs 44 of the spring bars 42 and 68 at the anti-rotation 40 of the locking body 30 together. Their design is chosen so that the locking lugs 44 in the assembled state under bias sit in the locking recesses 18 of the handle neck interior 14, and the webs 42 and 68, respectively are arcuately shaped so that they slide along the inner surfaces of the annular step 17 (See Fig. 6 and 7), when a relative movement between the assembly of Fig. 3 and the handle 10 takes place.

The handle neck 13 takes the seated in the hole 15 square 25, which in the dowel sleeve 45 (Fig. 1) is held, the sleeve part 46, the central bore 36 of the locking body socket 32 sliding leads. At the inner bottom of the ring body 20 comes Bund 49 of the dowel bush 45 to the plant. The axially inserted in her square hole 47 Square 25 presses expansion sections 48 (Figure 2) apart, which anchor the dowel sleeve 45 in the square hole 15 of the handle neck 12 and thus at the same time the Cause axial fixation of the entire assembly. This can be secured by gluing For example, by placing in the hole 15 before final assembly Adhesive introduces that hardens after insertion of the spreading 48.

As can be seen clearly from Fig. 2 and Fig. 4, the attachment cams 24 are parallel mutually extending oblique threaded holes 34 for receiving screws 35, which can be, for example, Allen screws and the profile of a (not shown) gear box from the front prevail or on other way frontally e.g. attack on a window frame. The ends 64 of the Cams 24 are provided with chamfers 66. In addition to the cam 24 can on Flange 22 of the main body 20 may be provided a recess 58, despite production-related Radii (about at the attachment points of the cam 24) a full concern the bottom surface 27 of the flange 22 allows at the mounting plane.

A lockable window handle 10 is shown in FIG. Its main ingredients are the same as described above. In addition, in a drehachs-parallel recess 52 used on the handle head 12 a generally designated 50 closing or locking unit, in the illustrated embodiment, a round cylinder 54 with a Locking or locking bolt 55 has the bottom in a bore 19 of the handle neck 13th is guided.

A key 56 allows the operation of the unit 50, so that the bolt 55 made the cylinder 54 is pushed down and out of the hole 19 out in the Cavity 62 of one of the extensions 60 occurs, provided that the handle 10 is pivoted to a position is in the cavity 62 and bolt 55 aligned with each other. One recognizes the synopsis of Fig. 5 and Fig. 6 and Fig. 7, that then in the cavity 62 located end of the bolt 55 with more than half its circumference of the associated extension 60 enclosed and in the adjacent locking recess 18 of the Handle neck 13 is pressed. This rich fit all around causes together with the so extended guide in the bore 19 and the resulting large load cross section over the entire length of the locking bolt 55 a remarkable stability in the lock or lock state. This results in a very high locking torque, although the radial distance of the pin 55 from the (in the middle of the Square 25) handle rotary axis because of the overall small dimensions is relatively small.

In the example of Fig. 7, the locking body 30 is opposite to that of Fig. 6 in that respect modified, as the opposing spring elements 40 of double webs 68 are formed. This increases the radial spring force of the locking lugs 44 considerably.

The invention is not limited to one of the above-described embodiments, but changeable in many ways. It can be seen that the novel handle has a robust structure, to its favorable properties, especially the most compact body 20 and the connectable to it - or, in another design, rigidly connected - locking body 30 contributes with its elastic rotation 40.

In summary, the invention provides an actuating handle, in particular a window handle 10, the or in the handle neck 13 a hole 15 for positive locking Recording a square 25 has. A handle body 13 superimposed main body 20th has cams 24 for attachment to a stop surface and is axially in the handle neck 13 embracing enclosed by this. To set preferred grip positions the main body 20 connected to a locking body 30 or connectable with the im Handle neck interior 14 located locking elements 18 interacts directly. A centric bore 26 stores and leads one of the square 25 interspersed, this in turn, in the handle neck interior 14 leading bush 32. In addition, the main body 20 mounted and guided with an outer seal 38 in the handle neck 12, the inside with is provided opposite locking recesses 18. These interact with Locking lugs 44 on an anti-rotation 40 together, with the socket 32 and / or the locking body 30 connected or connected, preferably even in one piece. The rotation lock is preferably a spring element 40 with at least two each other opposite webs 42 or double webs 68, in which locking lugs 44th can be brought into engagement with the locking elements 18 in the handle neck 12. In particular the spring element 40 arcuate, radially outwardly projecting and / or into the handle neck interior 14 directed webs, namely bearing one or two pairs of locking lugs 44, opposite webs 42 and 68. In the assembled state is the square 25 enclosed by a dowel bushing 45, the offset, on the edge surfaces has adjacent expansion portions 48 and with a sleeve member 46 the Socket 32 slidably supports. The main body 20 is through the front side on a Frame a profile, a gearbox or the like. obliquely inserted screws 35 fastened and has a flange 22, of which the cam 24 parallel to the axis the bore 26 protrude. Run obliquely to threaded holes 34, in which the Bolts 35 are retractable. Offset cam ends 64 are with insertion bevels Mistake.

In a lockable version is in the handle neck 12 a recess 52 for receiving a closing or locking unit 50 is present and the base body 20 has on the circumference at least one extension 60 with an outwardly open cavity 62, with a displaceable in the handle neck 12 locking or locking bolt 55 into engagement can be brought. Between the spring bars 42 are circumferential recesses present in which the extensions 60 are taken with a clamping fit. When locked, this is in the cavity 62 located end of the bolt 55 with more than half of his Surrounded circumference in rich form closure around the associated extension 60 and pressed into the adjacent detent recess 18 of the handle neck 13, which together with the extended guide in the bore 19 and over the entire length the bolt 55 acting, high load cross section remarkable stability and causes a large locking moment.
