Abstract

The window catch has a handle (14) mounted on a support housing (40) and with two coupling rings (52,62) which grip each other axially via two tags (64) diametrically opposite on one ring. The tags move between two stops (55) on the other ring. A locking bolt grips a locking hole (63) in one ring. In the locked position the catch can be moved into a ventilation position but not into the open position. The tags and stops provide a strong, robust coupling which is difficult to force.

Description

The invention relates to an actuating handle, in particular a window handle, According to the preamble of claim 1. Such an actuating handle is known from DE 85 14 560 U.

Lockable or lockable handles are known. Especially for rooms, which must be secured from the inside became lockable window handles developed in the locked state only from a 0 ° position to a 90 ° position are movable. In the 0 ° position, the handle lever points vertically below; the window is closed. In the 90 ° position, however, this can be done Swivel the window into a tilt position about a horizontal axis so that Limited room ventilation even without a suitable key can be. A further turning of the handle into a 180 ° position and thus one however, it is not possible to open the window completely. This only works if previously a button or locking bolt on the handling head is unlocked.

In order to achieve this, the handle neck is enclosed by a handle Coupling with mutually spring-loaded rings, which are used to engage and Disengage in or from given angular positions of the handle control tracks have, which are effective when turning the handle. The control lanes are in the form of raised and recessed alternating circular arc segments with intermediate sections on or on mutually facing narrow cylinder faces arranged. Ramps in Form of circumferential bevels make it possible, even when looking down closed locking pin 90 ° to the right or left of to move the closed position into the tilt position or vice versa. However the locked coupling elements prevent further rotation beyond the 90 ° position beyond what is only possible by closing the locking bolt. This relatively complex construction is only suitable for the transmission of medium-sized ones Torques, because the sawtooth-shaped claws are designed to lock or noses when a certain limit torque is exceeded shear off slightly. The handle does not guarantee a high level of security.

A handle described in DE-U-89 07 701 has a handle neck enclosing coupling ring with lugs in the form of radial spur gear as well as another coupling ring with a positive one Notch between opposing radial sawtooth sequences. This design is also complex and expensive due to the large number of components Circumstances prone to failure.

DE-U-85 14 560 discloses a lockable window handle with an im Grip head integrated locking pin, which is parallel to the by means of a locking cylinder Is axially displaceable. With the locking pin is an upper ring element a coupling connected to lock the handle head in different Angular positions has a further ring element. Both ring elements are provided with interlocking interlocking locking elements, the Window handle can only be locked in a 0 ° position. After unlocking it can the handgirff is free both in the 90 ° position and in the 180 ° position be pivoted. The window can be opened at will.

The aim of the invention is to provide a lockable operating handle, which is constructed simply and robustly from a few elements. The whole Opening or swiveling open a window provided with the handle only be possible if the handle is unlocked; for permanent ventilation through Tilting the window is an adjustable handle even when the handle is locked he wishes. In addition, the handle should be in the closed and tilted positions be lockable.

The features of the invention are in claim 1 specified. Refinements are the subject of claims 2 to 10.

With an operating handle, in particular a window handle, with a Handle head, which is axially fixed to a stop body, with a Locking element integrated in the handle head, which can be activated by means of a locking or locking unit is parallel to the axial direction, and with a clutch that two ring elements for locking the handle head in different angular positions with interlocking interlocking elements, wherein an upper ring member is axially slidably connected to the locking member is, the invention provides according to claim 1 that a driver device with a longitudinally displaceable slide is provided, the Grip head for actuating the slide which is guided in a longitudinally displaceable manner with the Driver device is coupled. Furthermore, the upper ring element at least two lugs, which uncouples freely between two stops pivotable and for positive coupling engagement in recesses are lowerable in the lower ring element. The grip head can be in one defined angular range from a closed position to an open position, e.g. a tilt position to be moved. One more turn and thus a complete one Opening the window is not possible due to the stops. If the noses are sunk in the provided recesses, the handle is in locked the intended stop positions, so that an unauthorized Do not close the window from the tilt position or open it without authorization is possible.

Here, it is advantageous if the lugs according to claim 2 each other are arranged opposite [and according to claim 3 form-fitting in the the provided recesses]. As a result, the handle is in its end positions always precisely locked; forced levering out is not possible. So that the handle can be pivoted in precisely defined angular ranges, are the depressions according to claim 3 at equidistant intervals along the outer ring circumference arranged.

The development of claim 4 is that the upper ring element directly attached to the locking member or in one piece with it, so that a there is a stable construction that can withstand high loads. Advantageous can the locking member according to the measure of claim 5 in at least three locking positions can be locked. For this purpose, claim 6 provides that the Closing or locking unit is a double-stroke cylinder. The lower ring element is, however, rotationally fixed according to claim 7 with the stop body connected or in one piece with it, reducing the number of assembly steps is further reduced. All of the above measures make it easy and robust construction of the operating handle, because the necessary Components are reduced to a few elements, which are also inexpensive have it made. Additional fasteners or compression springs are not required, which is an extremely simple and inexpensive assembly guaranteed.

The invention further provides in claim 8 that the ring elements along its inner circumference is a closed sequence of similar locking lugs have which interlock positively, wherein according to claim 9 of inner circumference of both coupling rings in a maximum number of teeth of sixteen Noses is divided. This training ensures a safe intervention the locking elements and a stable locking of the handle in the respective Angular positions, so that even by the transmission of very large Torques an opening of the handle is reliably prevented.

A preferred handle is characterized by the combination of features of the Claim 10 from that with an overall simple, clear structure and advantageous manufacturing and assembly a variety of practical uses offers and comfortable and safe handling guaranteed.

The window handle generally designated 10 in FIG. 1 has a handle head 12 with a handle main part 14, a coupling 50 with two ring elements 52, 62 and a stop plate 40 with a bearing opening 42.

The grip head 12 has, as shown in FIG. 2, a stepped circular cross section Well 16 for receiving the clutch 50 described below upper part 17 of the recess 16 is slightly conical and settles with a blind hole 18 upwards. Parallel to the axial direction A, but outside the axis of rotation D of the handle head 12, in the head 12 is a double-stroke locking cylinder 20 used with which a locking pin 22 moves back and forth in two stages can be.

In the upper part 17 of the recess 16 is through the bearing opening 42 Stop plate 40 through a bearing pin 24 inserted at its lower End has a shoulder 25 and conical according to the recess 17 is. It has a central threaded bore 26 into which the Window handle 10, a screw 28 is inserted, which in turn in the blind hole 18th engages in the head 12. Is located between the paragraph 25 and the stop plate 40 a bearing bush 30 while the bearing bolt is above the bearing opening 42 24 surrounding lower ring element 52 of the coupling 50 is arranged is. So that the grip head 12 does not touch the stop plate 40, is above the Ring element 52 also uses a spacer ring 32. By tightening the screw 28, the bolt 24 is rotatably fixed in the handle head 12, the is in turn connected to the stop plate 40 so that it can rotate axially.

It can be seen in Fig. 2 that in the stop plate 40 a recess 43 for receiving a slide drive 44 is present. This includes one with the Bearing pin 24 coupled gear 46 and a longitudinally displaceably mounted Slider 47 for actuating a (not shown) rotary or Tilt & Turn hardware.

The lower coupling ring 52 arranged above the bearing opening 42 has one Ring body 53 with four circumferential recesses arranged at equidistant intervals 54 (see FIG. 6), with two opposing ring body sections 55 between the recesses 54 are approximately twice as high as the remaining ring body 53. The inner edge 56 of the ring body 53 is also higher trained and carries on its end face 57, the spacer ring 32. To the Sixteen radial locking cams 58 are formed around the inner edge 56. As an anti-twist device opposite the stop plate 40 are on the underside of the ring 52 four cams 59 are present, which in matching holes 49 in the stop plate 40 intervene, which, for. B. define three locking positions for the handle 10.

The upper coupling ring 62 sits axially displaceably within the recess 16 in the grip head 12 and encloses the spacer ring 32 or the bearing pin 24. It is attached to the locking pin by means of a screw 23 via a radial extension 63 22 attached and can thus correspond to the axial locking positions of the Cylinder 20 can be locked in different positions. As in Fig. 5 too can be seen, the ring 62 also has sixteen locking cams 68 which are radial are arranged along the inner circumference 65; they correspond in size and Distance correspond to the cams 58 of the lower ring element 52. On the outside The circumference 66 of the upper ring 62 is two downward lugs 64 attached, the form-fitting in the four circumferential recesses 54 in the lower Ring 52 can intervene. The length of the lugs 64 corresponds approximately to the height of the highly formed ring body sections 55.

Fig. 2 shows the window handle 10 in the locked position. The upper clutch ring 62 is in the lowest latching position and is aligned such that the Lugs 64 in two opposite peripheral recesses 54 of the lower Engage clutch ring 52. At the same time there are the radially arranged locking cams 58, 68 of both rings 52, 62 in engagement with one another, so that pivoting of the handle head 12 and thus opening the window is not possible is.

If you close the cylinder 20 by one click, the upper one Clutch ring 62 raised; it reaches the position shown in FIG. 3. This is chosen so that the locking cams 58, 68 are disengaged and the Circumferential recesses 54 just release the side lugs 64 of the ring 62. This makes it possible to grip the handle 12 within the main body 14 one specified by the ring body sections 55 of the lower ring element 52 To pivot the angular range, the starting position of the Lugs 64 of the closed position of the handle 12, 14 and the end position of the 90 ° tilt position corresponds. A further turning of the handle 12, 14 over the tilt position in addition, however, due to the annular body sections 55 acting as stops not possible, so that a complete opening of the window is prevented. When the handle 12, 14 reaches the tilt position, the lugs 64 of the upper one can Coupling ring 62 again by actuating (pre-closing) the locking cylinder 20 be lowered. The side tabs 64 are in the circumferential recesses 54 sunk and the radial cams 58, 68 of the clutch 50 interlock. Of the Handle 12, 14 is thus securely locked even in the tilt position.

To enable the window to open completely, the upper one Coupling ring 62 with the locking cylinder brought into the second latching stage for this purpose 20 are placed in the top latching position (see Fig. 4). The side Lugs 64 of the upper ring 62 are then over the higher ring body sections 55 raised so that the handle 12, 14 freely between the 0 ° position and the 180 ° position can be pivoted.

The invention is not based on any of the previously described embodiments limited. For example, a Actuation of the handle lever 14 in the opposite pivoting direction (e.g. after left), only the lower ring element 52 has to be offset by 90 ° become. The tilt and open positions are then reversed. So it takes no further storage for additional components.

In another design, the lower ring body 52 can be integral with the Stop plate 40; the locking elements 54, 55, 58 are then immediately on the rosette body 40, which simplifies assembly.

It can be seen that a window handle 10 axially fixed to a stop body 40 rotatably mounted handle head 12 has a locking member 22, which is integrated by means of a double-stroke locking cylinder 20 parallel to the axial direction A in at least three locking positions can be locked. A coupling 50 has to lock the handle head 12 in different angular positions two ring elements 52, 62 with interlocking locking elements 54, 64, 58, 68. An upper ring element 62 according to the invention has at least two opposite arranged lugs 64, which can be freely pivoted between two stops 55 and in their stop positions with a precise fit in recesses 54 lower ring element 52 can be lowered. The upper ring element 62 is axially displaceable attached to the locking member 22, while the lower 52 rotatably with the stop body 40 is connected. Both ring elements 52, 62 have along their inner circumference 56, 65 is a closed sequence of sixteen in particular Similar locking lugs 58, 68, which interlock positively.
