Definitions

• the invention relates to an actuating handle for components such as windows, doors and the like according to the preamble of claim 1.
• Operating handles for operating windows and doors are known in numerous variants. They usually have a driver that can move an actuating device in a window or door sash, for example a window gear, by means of a handle.
• the driver can be designed as a square, for example.
• An operating handle is known from EP 1 683 933 B1, for example, in which a driver element can be anchored by a blocking or clamping element in the handle by pushing the driver element into the handle.
• One object of the invention is to create an operating handle with a particularly convenient quick attachment of a driver to an operating device in a window or door leaf, while at the same time the operating handle can be implemented without a rosette. It is preferred to be able to enable a latching function at the same time.
• An actuating handle for components such as windows, doors and the like is proposed, with at least one driver element which can be brought into engagement with a handle in a rotationally fixed manner, and a gear nut for integration into a window or door gear.
• the invention is characterized in that the gear nut has a recess extending through an axis of rotation of the gear nut with at least one spring-loaded blocking or clamping element pivotably mounted therein, the blocking or clamping element being force-, form- and/or can be brought into frictional engagement, and that the gear nut has radially inwardly directed latching recesses on its outer circumference for receiving latching elements.
• the gear nut is a component that is installed in a window gear or similar in order to drive other elements there.
• the gear nut has an external toothing which engages, for example, with a toothed rack or other correspondingly toothed elements. If the gear nut is rotated by the driver element, this consequently sets the window gear in motion.
• the gear nut can be fully integrated into the window gear and is therefore located entirely in the relevant window or door sash.
• the gear nut has a recess which preferably extends completely through the gear nut in the axial direction.
• the driver element protrudes through the recess in order to establish a non-rotatable connection with the gear nut.
• at least one blocking or clamping element is arranged in the recess and is designed to establish a connection with the driver element by pushing it in. This is preferably achieved as described in EP 1 683 933 B1 by the driver element being inserted into the recess and engaging there with the blocking or clamping element so that these are connected to one another.
• the locking or clamping element allows a variable orientation when inserting the driver element due to the spring-loaded mounting, so that the movement of the driver element can be followed for the two elements to engage in one another. At the same time, the locking or clamping element can be prevented from being pulled out by wedging it with the driver element.
• a latching function can also be implemented in that the gear nut has latching depressions on the peripheral side.
• spring-loaded latching means can be provided in the window gear, which are directed radially onto the gear nut by spring force and press on its circumference.
• the latching depressions allow selective engagement between the latching means and the latching depressions, which leads to a latching force which is released again by applying a sufficient torque to the driver element.
• the release force or the release torque can be adjusted by dimensioning the locking means, the locking recesses and the spring force.
• the integration of such a device for connecting the driver element to a window gear and the locking function in a gear nut leads to a particularly simple, compact and complete integration in the window or door leaf.
• Separate connecting means or latching means outside of the window or door leaf are not necessary and the actuating handle according to the invention can be designed completely without a rosette. No modifications have to be made to any openings or cutouts in the window or door leaf as long as the drive nut does not exceed the usual, specified and/or standardized dimensions.
• the gear nut is divided into two axial halves and the recess extends over the two halves. The recess can be made by machining both halves and then assembling them.
• more complex shapes of the recess can also be produced. For example, shoulders or edges can be realized in the recess, against which the blocking or clamping element can come into contact.
• the two halves can be screwed or glued together axially after the blocking or clamping element has been inserted into the gear nut.
• the recess has an undercut to secure the blocking or clamping element.
• the recess can have an undercut in both axial directions, so that a diameter of the recess, facing inwards in the axial direction, suddenly increases at least at one point. Two such jumps in diameter can be provided, which are spaced apart from one another and delimit the undercut opposite one another and create a cavity for receiving the blocking or clamping element. Both undercuts are then preferably designed symmetrically and arranged symmetrically to one another.
• the blocking or clamping element has a clamping frame which has an opening complementary to a profile of the driver element for receiving and enclosing the driver element.
• the driver element can extend through the opening of the clamping frame. Due to the pivotable, spring-loaded mounting, the clamping frame can be aligned obliquely to the driver element after the driver element has been inserted—depending on the size of the opening of the driver element. In particular in the case of sharp contours of the opening, the clamping frame can then become wedged with the driver element when the direction of movement of the driver element is reversed.
• the clamping frame can be designed in such a way that if the force applied in the opposite direction is continued to move out the driver element, the clamping frame is positioned even more obliquely and the two elements thereby become even more wedged into one another.
• the clamping frame can be pivoted between a first position and a second position, with a surface normal of a plane spanned by the clamping frame running obliquely to the axis of rotation in the first position and the surface normal running parallel to the axis of rotation in the second position.
• the pivot axis can run perpendicularly to the axis of rotation and consequently extend transversely through a longitudinal axis of the driver element.
• the pivot axis could be diagonal to a Cross-sectional area of the driver element are.
• the clamping frame can become wedged on two surfaces of the driver element that are adjacent to one another when it is positioned at an angle.
• the clamping frame is at least largely in the second position, it is possible to guide the driver element through. Due to the resilient mounting, the clamping frame preferably always pushes into the first position, but the clamping frame is pushed in the direction of the second position as a result of the driver element being pushed through.
• the recess could have a sloping inner, end-side boundary surface against which the clamping frame can nestle to assume the first position. Consequently, when the driver element is not inserted, the gear nut is in a state that allows the driver element to be pushed in, in that the driver element always presses the clamping frame slightly against the spring force, so that the driver element can slip through the opening of the clamping frame.
• the clamping frame already has an orientation at the beginning of the process that is as oblique as possible. The alignment in a neutral state can be guaranteed by the appropriately designed, inner, end-face boundary surface.
• a contour of the clamping frame is designed to complement an inner contour of the recess.
• the clamping frame fills the inner contour of the recess. It can transmit torque if the contours are not circular. A slight difference in size between the contours of the clamping frame and the inner contour of the recess allows the clamping frame to pivot sufficiently.
• the at least one blocking or clamping element has two clamping frames between which a compression spring is arranged.
• the driver element can then be wedged with one of the two clamping frames, depending on the direction from which it is inserted into the gear nut. It is therefore suitable for left-hand and right-hand rotation immediately after installation. It is not necessary to check the alignment and turn the gear nut before installing it in a window gear.
• the recess When using two clamping frames, the recess preferably has two inner, end-side boundary surfaces that lie opposite one another and run in a mirror-inverted manner, against which one of the clamping frames can nestle in order to assume its first position. Installation from both directions leads to reliable wedging of the clamping frame and the driver element.
• the driver element can still be inserted into the gear nut from both directions in order not to have to turn it.
• a pin could be inserted from the outside transversely to the axis of rotation through a transverse bore in the gear nut in order to move one of the two clamping frames, which is later to be inactive, into a second position to enable the driver element to slip through and to hold it there permanently.
• the surface normal of a plane that is spanned by the held clamping frame is then parallel to the axis of rotation.
• the opening of the clamping frame is aligned with the driver element and does not counteract an axial movement of the driver element. After the driver element has been pushed through, this clamping frame only serves as an abutment for a compression spring located between the clamping frames.
• the gear nut has two transverse bores into which a pin can be inserted in order to hold one of the clamping frames vertically in relation to the axis of rotation.
• the gear nut has a cutout arranged next to the recess for the passage of a tool for moving the blocking or clamping element against a spring force.
• the tool can be an elongate element that is inserted through the cutout in the gear nut and comes into contact with the blocking or clamping element there. This can then be moved accordingly against the spring force in order to release the wedging with the driver element and consequently release the driver element again.
• the cutout can have a significantly smaller size than the recess. For example, it could have a width of only 3mm or less to insert a suitable tool such as a fine screwdriver or wrench.
• the cutout could be arranged at the edge of the recess. A distance could be provided between the recess and the cutout, but this is not necessary.
• the latching depressions are spaced evenly apart from one another in the circumferential direction.
• the distance between the locking recesses depends on the desired locking positions. It is conceivable to integrate at least three detent positions spaced 45° apart to signal the handle positions for a closed, fully open or tilted window.
• the locking depressions have a profile of a segment of a circle.
• spherical or spherical segment-shaped locking elements in the Engage in the locking recesses and be reliably released again.
• the segment height or the central angle of the profile of the latching recesses can also determine the force with which the latching element is held in the latching recess.

• FIG. 2a and 2b shows a window gear with a gear nut arranged therein.
• Fig. 3a to 3c an operating handle in an exploded view (3a), an assembly (3b) and the release of the handle (3c) on a window sash.
• the gear nut 2 for integration into a window or door gear.
• the gear nut 2 has two axial halves 4 and 6 which, when put together, form a body of the gear nut 2 . It is intended to be rotated about an axis of rotation 8 . It has a recess 10 which extends completely through the gear nut 2 along the axis of rotation 8 . It widens inward from the front. After passing through roughly a third of the axial thickness of the half 4 or 6 in question, an undercut 12 is provided, which leads to the formation of a cavity 14 .
• a clamping frame 16 is arranged in the cavity 14 and is urged in the direction of the undercut 12 by a compression spring 18 .
• the undercut 12 is significantly more pronounced in a lower area of the plane of the drawing than in an upper area of the plane of the drawing.
• an inclined plane 13 running transversely to the axis of rotation 8 is formed by an inner, end-side boundary surface 15 . This is in a first spatial direction at an angle a obliquely to an end face 20 of the gear nut 2, through which a driver element can be inserted into the cavity 14.
• the plane 13 is also inclined by a second spatial direction by a further angle ß to the end face 20.
• a surface normal 17 of a plane spanned by the clamping frame 16 is consequently, when the clamping frame 16 rests on the inner, end-side boundary surface 15, around the relevant spatial directions oblique to the axis of rotation 8. This is referred to previously as “first position”. This is the position that the clamping frame 16 assumes in an unloaded state, since the compression spring 18 urges it against the inner, end-side boundary surface 15 . In the state shown in FIG. 1, the surface normal 17 runs parallel to the axis of rotation 8. This is referred to above as the “second position”.
• the clamping frame 16 has a contour 22 which corresponds to an inner contour 24 .
• the contours 22 and 24 are flattened in areas and, for example, have the shape of a square with rounded corners. Due to this non-circular shape, a torque can be transmitted between the relevant axial half 4 or 6 and the clamping frame 16 .
• the clamping frame has a centrally arranged opening 26 whose center runs approximately through the axis of rotation 8 .
• the opening 26 is designed to complement a driver element (not shown here).
• the driver element can be pushed through the recess 10 into the gear nut 2 and through the clamping frame 16 . Since the clamping frame 16 is inclined due to the spring force acting on it, it is raised somewhat when the driver element is pushed in, so that it approaches the second position.
• the opening 26 allows the driver element to be inserted and pushed through there. At rest, when the driver element is pushed in, the clamping frame assumes the greatest possible angle relative to the end face 20, which angle depends on the driver element.
• the opening 26 is preferably designed with sharp edges and is therefore designed to wedge with the driver element.
• the driver element leads to an even stronger wedging, so that the driver element remains in the recess 10 and can practically no longer be pulled out.
• the clamping frame 16 By inserting an elongate tool into a cutout 28 which is adjacent to the recess 10, the clamping frame 16 can be brought from the outside into a position which is largely perpendicular to the axis of rotation 8. As a result, the edges of the opening 26 are released from the driver element and thus the wedging, and the driver element can be pulled out of the recess 10 .
• the gear nut 2 has a toothing 30 on its outer circumference, which serves to engage in a corresponding toothing of a gear element in a window or door gear. Furthermore, latching depressions 32 are provided, which can carry out latching with latching elements (not shown here).
• Fig. 2a shows a partial section of a window gear 34, in which the gear nut 2 is used.
• the window gear 34 is shown in an assembled condition.
• a push rod 36 is provided here, which meshes with the teeth 30 of the gear nut 2 . If a driver element is inserted in the recess 10, the gear nut 2 can be rotated, which leads to a linear pushing movement of the push rod 36.
• latching elements 38 engage in latching depressions 32 of the gear nut 2, so that the gear nut 2 is held in predetermined rotational positions with a certain force.
• the locking elements 38 can be released from the locking recesses 32 and the gear nut 2 continues to rotate.
• the user of an actuating handle, in which the gear nut 2 is integrated, can hereby haptically and acoustically recognize that certain rotational positions have been reached.
• the latching elements 38 are designed as balls, for example, which are each pressed radially onto the gear nut 2 by a compression spring 40 .

• FIG. Here, the clamping frame 16 is brought into a position that is essentially vertical to the axis of rotation 8, i.e. the second position, so that the wedging with the driver element 50 is canceled. This can be seen in Figure 4b.
• 5a shows an exploded view of a gear nut 56, which is somewhat modified compared to the gear nut 2 from the previous illustrations. Furthermore, housing parts 58 are shown which belong to the window gear 34 and accommodate the gear nut 56 .
