The locking cylinder has a fixed wall in which the latching mechanism guides a radially moving pin (48). A key (S) is used to open the lock.

Description

The invention relates to an actuating handle for doors, windows or the like. according to the preamble of claim 1 and claim 6.

For doors locking systems are in use, the authorized persons only Allow access. Keys other than for such locking systems are usually needed for lockable window handles. But you need for certain applications Handling systems that allow it even without a separate key, if necessary opening and closing windows or other room closures by yourself To organize users and still allow an operator for example, for ventilation.

For occasionally suppressed spin-entrainment of an associated device, such as a lock nut or a window gear, are handles of different constructions known. Thus, DE-U-8 624 544 provides for mounting on a frame a stop body before, with which the handle is axially fixed and the locking means contains, define the preferred or standard angular positions of a handle. Also, EP-B-0 386 651 and EP-B-0 460 297 each describe a lockable one Window handle with a two-stage jaw clutch lock that pivoting of the window only possible when the handle is unlocked. One can thus cause a tilted position of the window even when the handle is closed, so that Room ventilation can always be carried out, even by operating personnel, that does not have keys.

Some window handles have a push-button unit as an axially movable securing element, which, however, even unauthorized persons by simply impressing or disengaging the Can bring or change the closing state, which in some uses is undesirable and may even be inadmissible.

DE-U-299 13 559 describes a handle, optionally with or without locking means can be used. He lets himself - especially on site - with a cylinder equip which e.g. in exchange for an alternative system at any time is removable. For this purpose, the handle neck on a recess into which a Schließanlagenfähiger Lock cylinder is fitted, which is connected to a locking ring on a Adapter attacks. This can be rigidly arranged at the lower end of the lock cylinder core be. However, only two end positions of the lock cylinder are selectable.

It is an important object of the invention to improve by economic means lockable handle with a slim as possible or a little chunky To create handle neck, the different operations for requirements increased Security possible. The aim is a handle construction that is simpler, cheaper Manufacturing and assembly a reliable handling allowed.

Main features of the invention are set out in claim 1 and in claim 6. Embodiments are the subject of claims 2 to 5 and 7 to 14.

In an actuating handle for doors, windows or the like., With a rosette for mounting a rotatable handle whose neck with a storage inside the rosette axially fixed, e.g. is crimped, with a located in the handle head lock cylinder and with an axially displaceable locking bolt, with the locking element can be coupled and locked in predetermined angular positions of the handle with the rosette, the invention according to claim 1, that with the lock cylinder axially displaceable, connected in the axial direction spring-loaded locking means which in a defined handle-rotational angle position automatically assumes a detent position. These new and very effective design ensures a whole lot more reliable Users options.

According to claim 2, the locking means is a locking bolt arranged in the lock cylinder, the spring-loaded in the axial direction is displaceable and according to claim 3 on graded annular surfaces slides. The measure of claim 4 contributes to this, after which the latching means is guided in the lock cylinder, which is because of the safe Movement take a significant improvement over the state of the art Technikdarstellt.

In the design of claim 5, the lock cylinder has a non-rotatable wall, in which is axially guided by the locking means radially projecting pin, preferably in a straight longitudinal groove, which directs the stroke of the locking means.

Furthermore, the independent claim 6 sees in a handle of the aforementioned Art ago that the lock cylinder has a core, which provided with a radial breakthrough is, the movement-controlling one of the locking means radially projecting pin leads. This allows the course of the movement to be simple and reliable Set way, preferably by the breakthrough of claim 7 one of the pin interspersed curve window is. Its shape can be tailored to the needs of the individual Adapt applications.

It is advantageous if the breakthrough according to claim 8 has an angled contour, wherein a lower boundary has a flat segment which extends over a trough in a steeper segment passes, in particular a steep flank. This will be the extent of the stroke defined in a structurally particularly simple manner. Furthermore, claim 9 provides that the breakthrough at an upper boundary two axially offset one another having straight edges which are substantially horizontal or transverse to the cylinder axis run and end at a vertical intermediate edge above the trough.

Another feature of the curve window is given in claim 10, wherein side edges the breakthrough for the pin form stops, with the breakthrough loud Claim 11 expedient over a circumferential angle of at least 180 °, preferably 220 ° is enough.

In claim 12, the important feature of the handle is defined that in in the Locking cylinder inserted key for pivoting the handle from a transverse in the up-vertical position requires two-handed operation. You have it An effective child safety device that helps to prevent accidents. Special is the handle according to claim 13 from a transverse position (3 o'clock position or 9 o'clock position) only pivoted upward while the key is rotated against spring force.

Claim 14 provides that when pivoting the handle from the upward-vertical position (12 o'clock position) in a transverse position (3 o'clock or 9 o'clock position) of the locking bolt can be latched behind a Tangentialanschlag under spring force, regardless of whether the key is in the lock cylinder or not.

It can be seen in Fig. 1 in a rosette 20 axialfest / rotatably mounted, general with 10 designated window handle, the handle head 12 shown partially cut is to allow a view into the interior. The rosette 20 has stop cams 21 (FIGS. 3, 4, 7) and a reinforcing plate 22 with screw holes 24. In addition to these is on both sides depending on a bolt hole 64. A cover plate 28, the is supported on the bottom of the handle head 12 with a compression spring 38, overlaps the Rosette 20. This has a central opening, in which the rosette 20 - velvet a bolt sleeve 30 secured in or integral therewith - from a square 26 is penetrated centrally, which engages in the handle head 12 in a square hole 16.

Parallel to the square hole 16 there is also a paraxial round hole 14, which receives a lock cylinder 18, the core 40 of which is a compression spring 42 constantly axially loaded locking bolt 44 axially movable leads, see the detailed drawings Fig. 8a and 8b. A snap ring 29 (Figures 4 to 6) secures the lock cylinder 18 against axial tension. Two diametrically opposed longitudinal grooves 19 extend in the lock cylinder wall 60 parallel to the axis A (Fig.7) and serve to accommodate the (not shown) tumblers of the lock cylinder 18, if the key S should be deducted. A pin 48 coming from the latch bolt 44 protrudes radially, this leads rotatably in a (not shown) longitudinal groove, which between the grooves 19 in the lock cylinder wall 60 is located. An annular flange 32 of the locking sleeve 30 has an upstanding semi-circular collar 34 and - Supplement to the full circle - an axially receding to the collar 34, lower half-ring surface 36, introduced as an interlocking part an axially parallel indentation 46 is. She sets the locking bolt 44 on the circumference to lock the handle 10 and secure against rotation.

Important is the cylinder core 40, a radial opening 50, the lower limit from a flat, approximately horizontally extending helical section or segment 52 and a subsequent, steeper (helical) segment 56 are formed. At the kinking transition between the segments 52, 56 is a trough 54th The flat segment 52 preferably extends through an angle of 180 °, while the steep flank 56 emanating from the trough 54 makes an angle of e.g. 40 °. At the side edges of the aperture 50, the segment ends for the pin 48 each form a stop. At the top, straight edges converge towards each other on both sides, namely a slightly inclined edge 62 and a horizontal edge 66, in such a way axially offset from each other that at a vertical intermediate edge 58 above the Trough 54 is formed a vertical stop step.

The following explains the function of the handle. First, there is the Window handle 10 in the basic position of Fig. 1, so that the handle main body parallel to Longitudinal direction of the rosette 20 is down. The angular position of the key S-comp. Fig. 1a - is referred to as 6 o'clock position. In this case, the pin 48 is in Stop at the end of the flat segment 52 (left in the picture), and the locking bolt 44 has entered the concavity 46. From the completed handle 10 of the Key S are withdrawn, i. You have a first operating state as in any lockable window handle.

In Fig. 2, the window handle 10 is also in the down position parallel to the longitudinal direction of the rosette 20, but the key S is shown in FIG. 2a in the 12 o'clock position, ie the lock cylinder 18 is compared to FIG ° turned. As a result, the pin 48 passes over the flat segment 52 into the trough 54 and thus the locking bolt 44 with its lower end just above the semi-circular surface 36, out of engagement with the concavity 46 (see Fig .. 5 and 6). The key S is removable and the handle 10 can be pivoted to a transverse position (to the left in the 3 o'clock position, Figs. 3 and 3a, or to the right in the 9 o'clock position, not drawn), the locking bolt 44 comes to one of two stage or tangential stops 68 of the semicircular collar 34 to the plant. This is a second operating state which in cooperation with a TBT-window transmission [ "t ILT b efore t urn" mode: first butts, then Panning] provides increased security. For example, anyone, including a child, can not open the partially-closed windows, such as for ventilation-without keys S, or open them.

To get to the position of Fig. 4, a two-hand operation is required. you Turns the lock cylinder 18 with one hand on the key S to the right in the [other] end position (Fig. 4a), wherein the pin 48 at the end of the steep flank of the segment 56 comes to a stop. The locking bolt 44 is thereby reduced maximum, so that the other hand the window handle 10 in its vertical position (12 o'clock position, Fig. 5) can bring. In this third state, the window can be pivoted to open. Regardless of whether the key is infected or not, it will cause it to swing down of the handle 10 in a transverse position always for locking the locking bolt 44 on a the tangential stops 68, because the large slope of the segment 56 is a self-locking excludes. This position is still given in Fig. 6, but is the Key S deducted. So that's done in the 6 o'clock position of the key S. The locking cylinder18 had to be turned back so far that the Pin 48 at the intermediate edge 58 reaches the circumferential position of the trough 54 and tangential strikes while the locking bolt 44 spring loaded on the semicircular collar 34 of the Ring flange 32 rests.

Once the locking bolt 44 in the keyless pivoting back of the handle 10 in the Position of Fig. 7 and 7a passes over the tangential stop 68, the pin 48 locks under the force of the compression spring 42 in the trough 54 a. The free end face of the locking bolt 44 then floats above the semi-annular surface 36 of the annular flange 32.

The invention is not limited to one of the above-described embodiments, but in various ways modifiable, depending on the door, window or the like. given requirements. It exceeds the possibilities of conventional ones Technique, which is unhindered at only two positions of the lock cylinder Panning a window handle or its partial rotation allowed. The inventive Window handle 10 is shut off in its basic position and the window remains with the key removed S always safe, because it can be tilted or closed, but not be opened. Even if accidentally stuck Key S acts the lock cylinder 18 still as child safety, because you both Hands needed to move the handle 10 from a transverse to an upright vertical position (12 o'clock position, Fig. 5a and 6a) to move: the handle 10 can only swing up, while a hand turns on the steep flank 56 torsion spring key S, so the locking bolt 44 overcomes the tangential stop 68.

In summary, it should be noted that a preferred embodiment of a Operating handle for doors, windows or the like., With a rosette 20 for mounting a rotary handle 10, in the handle head 12 a lock cylinder 18 with a spring-loaded axially displaceable locking bolt 44 has, in a defined handle-rotational angle position automatically takes a rest position by using a free End over a trained as a stepped locking sleeve locking element 30 of the rosette 20th is slidable. The lock cylinder 18 has a non-rotatable wall 58 and a core 40th with a radial aperture 50, one of the locking bolt 44 radially protruding pin 48 motion control leads. The breakthrough 50 reaches over one Circumferential angle of at least 180 °, preferably 220 °, and forms curve window in Shape of an angled contour, which is a flat segment 52 below, over a Trough 54 merges into a steeper segment (steep flank) 56. Above are two axially offset straight edge portions 62, 66 present on a vertical Intermediate edge 58 above the trough 54 end, with breakthrough side edges for Make the pin 48 stops. When inserted into the lock cylinder 18 key S is to handle pivoting from a transverse to the upward vertical position a two-handed operation required. Swinging the handle 10 down in a transverse position (3 o'clock or 9 o'clock position), so the locking bolt 44 locks under spring force behind a Tangential stop 68 on whether the key S is in the lock cylinder 18 or not.

All arising from the claims, the description and the drawings Features and benefits, including structural details, spatial Arrangements and method steps, both for themselves and in the various combinations are essential to the invention.
