Abstract

An actuating handle for components such as windows, doors and the like is proposed, with a driver element which is non-rotatably connected to a handle and a substructure device for attachment to a window or door frame, the driver element being engageable with the substructure device. According to the invention, it is provided that the handle has a cavity through which the driver element extends axially outwards, that the substructure device has a recess shaped complementarily to the driver element for pushing the driver element through, and that the substructure device can be inserted completely into the cavity and has at least one pivotally mounted, spring-loaded blocking or clamping element which can be brought into engagement with the driver element in a non-positive, positive and/or frictional manner.

Description

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 an elongate driver element that can move an actuating device in a window or door leaf, for example a window gear, by means of a handle. The driver element is often designed as a square.

To open and close the window or door, in addition to the rotary movement, it is also necessary to transmit a tensile or compressive force to the window or door sash. For this purpose, a connection between the handle and the driver element is designed in such a way that they are connected to one another axially and in a torque-proof manner after assembly.

It is known to realize actuation handles without rosettes on a window and door leaf. However, this leads to a very limited installation space for mechanical elements between the handle and a window mechanism. The attachment of the driver element on the handle is also often realized by a grub screw. If a lock is also provided for the actuator in question, the grub screw is screwed in from above due to the positioning of the lock cylinder, which is optically disadvantageous.

Out of EP 1 683 933 B1 an actuating handle is known 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 actuating handle that can be attached to a window or door leaf in a particularly simple manner and preferably without visible screwing, while at the same time the actuating handle can be implemented without a rosette.

Main features of the invention are set out in the characterizing part of claim 1. Configurations are the subject of claims 2 to 9.

An actuating handle for components such as windows, doors and the like is proposed, with a driver element which is non-rotatably connected to a handle and a substructure device for attachment to a window or door frame, the driver element being engageable with the substructure device. According to the invention, it is provided that the handle has a cavity through which the driver element extends axially outwards, that the substructure device has a recess shaped complementarily to the driver element for pushing the driver element through, and that the substructure device can be inserted completely into the cavity and has at least one pivotally mounted, spring-loaded blocking or clamping element which can be brought into engagement with the driver element in a non-positive, positive and/or frictional manner.

The actuating handle according to the invention can consequently be implemented without a visible screw connection and preferably without a rosette. The driver element is non-rotatably connected to the handle. Both parts are glued together or inseparably connected to one another in some other way. A grub screw for attaching the driver element to the handle is therefore not required. At the same time, the driver element extends outwards through a hollow space in the handle in order to be connected to a window or door mechanism.

The peripheral surface of the substructure device is designed to be complementary to the cavity and can therefore be completely accommodated by the cavity. The hollow space is on a side facing the window or the door when installed limited axially by an opening contour. The cavity extends from the opening contour into the handle and could have a shoulder surface or some other internal, axial limitation there. The substructure device is designed to receive the driver element and at the same time allow the driver element to be introduced into a window or door mechanism in that the driver element can be pushed through the recess along its longitudinal axis. When the operating handle is installed on the window or door, the substructure device is located completely between the opening contour and the inner boundary surface.

The substructure device serves to mechanically connect the handle to the window or door leaf. It is conceivable that the substructure device enters into a screw connection with the window or door sash and by pushing in the driver element, a non-positive, positive and/or frictional connection is achieved between the driver element and the substructure device. Since the driver element is non-rotatably connected to the handle, the handle is consequently also connected to the window or door leaf via the substructure device. Since the substructure device can be positioned completely in the hollow space, the handle with the opening contour can end directly with the window or door leaf, or with the formation of a gap. The actuating handle can consequently be implemented without a rosette, since the substructure device is not visible when the handle is in the attached state.

The substructure device has a recess which preferably extends completely through the substructure device in the axial direction, so that the driver element can be introduced into the window or door leaf through the substructure device. Provision is made for the driver element to protrude through the recess in order to establish an axial connection with the substructure device. For this purpose, 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 preferred as in EP 1 683 933 B1 described achieved by the driver element is inserted into the recess and there comes into engagement with the blocking or clamping element, so that they are connected to each other. The blocking 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. Due to the arrangement of the blocking or clamping element within the substructure device, it is also not necessary to provide a rosette or other elements that increase the installation space, which are above the door or

Window sashes protrude outwards. Nevertheless, a secure connection can be made between the driver element and the door or window gear.

In an advantageous embodiment, the substructure device has at least two cams facing away from the handle for insertion into complementary cam bores in the window or door frame. An alignment of the substructure device on the window or door leaf can be enforced by the cams. For this purpose, it is equipped with complementary cam bores into which the cams are inserted. By screwing the substructure device in the orientation then determined, it is held and the handle attached to the substructure device is consequently also correctly aligned for use.

The cavity of the handle could also have a radial inner surface with latching recesses, with the substructure device having at least one latching web extending in the radial direction for releasably latching into the latching recesses. The radial inner surface surrounds the hollow space of the handle and allows the locking webs to snap into place in the locking recesses when the handle is actuated. It is provided here that the latching webs are connected to the substructure device in a rotationally fixed manner, so that they always retain their position regardless of the twisting of the handle. If the handle is turned, the locking depressions follow the rotation and can snap into the locking depressions depending on their arrangement on the radial inner surface. The latching webs are preferably designed to be radially resilient, so that they not only easily snap into place, but can also be easily released from the latching depressions. The aim is to provide a user with haptic feedback when a certain rotational position has been reached, while at the same time holding the handle slightly in this position.

It could be useful for the substructure device to have two diametrically opposite latching webs, with the radial inner surface having at least four latching depressions evenly spaced from one another. The latching webs can simultaneously latch into opposite latching depressions. When using four locking recesses, locking occurs in 90° steps. Due to a larger number of detent recesses, a significantly finer detent, for example in 45° increments.

Provision is particularly advantageously made for the at least one latching web to be arranged on a latching element which is arranged on a side of the substructure device facing the handle and acts as a mounting stop for the handle. The handle then assumes a predetermined axial position during assembly, which leads to a harmonious shape without rosettes.

It is preferred that the latching element is designed to be axially resilient in order to exert an axial prestressing force after the actuating handle has been installed. Any axial play can thus be reduced or completely compensated for.

The substructure device particularly preferably has a rotatably mounted insert in which the blocking or clamping element is arranged. The handle can then still rotate freely, but is axially held in place by the blocking or clamping element, regardless of its rotational position. The insert can be mounted using a simple plain bearing or a corresponding bore with a suitable fit.

In an advantageous embodiment it is provided that the at least one 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.

It is also favorable if 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 a longitudinal axis of the driver element in the first position and the surface normal running parallel to the longitudinal axis in the second position runs. The pivot axis can be perpendicular to the longitudinal axis and consequently extend transversely through the longitudinal axis of the driver element. For example, the pivot axis could lie diagonally to a cross-sectional area of the driver element. As a result, 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. If 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.

In an advantageous embodiment, the handle has an opening for passing through a tool for moving the blocking or clamping element against a spring force. The tool can move to the blocking or clamping element and there move the clamping frame or other suitable element against the spring force in order to release the driver element from its axial attachment.

The driver element could have a projection on one longitudinal side, with the recess having a radially outwardly directed cutout on a boundary edge, which is designed for pushing the projection past. By positioning a local cutout at a suitable point on the boundary edge, the driver element can be inserted into the recess and pushed through completely in only one rotational position. The projection can then be moved past the pertinent boundary edge through the cutout. If the driver element is not correctly aligned, the projection can come into contact with one of the delimiting edges and consequently the driver element then does not reach the blocking or clamping element either. This prevents incorrect assembly.

1 shows an operating handle 2 for windows, doors and the like. Here a handle 4 is shown, which has a cavity 6, from which a driver element 8 extends to the outside. The driver element 8 is designed here as an elongated square and is glued to the handle 4 or otherwise permanently connected to it. A substructure device 10 is shown separately here, which can be attached to a window or door frame. It has a recess 12 through which the driver element 8 can be inserted so that it emerges at its end, which is not visible here. The substructure device 10 is designed to complement the cavity 6 so that it can be fully inserted into the cavity 6 .

2 shows the actuating handle 2, in which the substructure device 10 has been pushed completely into the cavity 6 and is largely flush with an opening contour 14 of the cavity 6. The driver element 8 protrudes clearly beyond the opening contour 14 and can thus be connected to a window or door mechanism that is arranged in a window or door frame. The substructure device 10 is equipped with cams 16 which extend over the opening contour 14 . As shown in a subsequent figure, the cams 16 can be used to fix the alignment of the substructure device 10 in corresponding cam bores of a window or door frame.

3 shows an exploded view of the substructure device 10. The substructure device 10 has a lower part 18 on which the cams 16 are arranged. An insert 22 is inserted through a circular hole 20, which insert has a first lateral surface 24, a second lateral surface 26 with a larger diameter and an annular shoulder surface 28 lying in between. The lower part 22 is inserted into the hole 20 in such a way that the first lateral surface 24 can rotate in the hole 20 and the heel surface 28 rests on the side of the lower part 18 facing the cams 16 . Here is the recess 12 with which the driver element 8 is connected. As a result, the lower part 22 follows the rotation of the handle 4 in the fully installed state.

A latching element 30 is placed on the first lateral surface 24 so that the latching element 30 and the insert 22 enclose the lower part 18 . The latching element 30 has two opposite latching webs 32 which are designed to be radially resilient. Furthermore, the lower part 18 has a plurality of bores 34 which allow the lower part 18 to be screwed to a window or door frame. The bores 34 are later covered by the latching element 30 . For the precise connection of the latching element 30 to the lower part 18 , the latter has two projections 36 which are arranged opposite one another and enclose corresponding indentations 38 of the latching element 30 . The two elements 18 and 30 are preferably with a Formed a press fit, so that the locking element 30 can be placed firmly on the lower part 18 . A bezel 40 snaps together with the base 18 and holds the base 18 and insert 22 assembly together.

The locking element 30 can also function as an axial stop for the handle 4 . In order to cushion an axial play, which can arise in the proposed connection, the latching element 30 is additionally designed to be resilient in the axial direction. The latching webs 32 protrude a small distance toward the handle 4 and are deformed by this distance when the handle 4 is mounted. The distance could be about 0.2 mm. This results in a preload with a force of about 50N, for example. This force cushions any axial play that may occur.

4 shows part of a window frame 42 on which the substructure device 10 is mounted, with fastening screws 44 and the locking element 30 being shown separately here. After the screws 44 have been tightened, the latching element 30 is put on and then the handle 4 is pushed onto the substructure device 10 in order to insert the driver element 8 .

As mentioned above, the cams 16 can be inserted into cam bores 46 of the window frame 42. this is in figure 5 shown. Also shown here are mounting holes 48 for the screws 44 and a mounting opening 50 for the driver element 8. The cam holes 46 and the mounting holes 48 for the screws 44 could be produced using a drilling template or jig.

6 shows the insert 22 in an exploded view. Here the orientation is reversed as in 3 chosen. The insert 22 has a rotor 52 which has the first lateral surface 24 . A sloping bearing surface 54 is arranged on an inner front end, onto which a clamping frame 56 is urged by means of a compression spring 58 . A surface normal 60 of a plane spanned by clamping frame 56 is therefore inclined by two spatial directions to an axis of rotation 62 of insert 22 when clamping frame 56 is lying on support surface 54, wherein axis of rotation 62 is at the same time the longitudinal axis of driver element 8. This is hereinafter referred to as "first position". This is the position that the clamping frame 54 assumes in an unloaded state, since the compression spring 58 urges it against the bearing surface 54 .

When the driver element 8 is inserted, the clamping frame 56 straightens up somewhat, so that the surface normal 60 lies largely parallel to the axis of rotation 62 . This is hereinafter referred to as "second position". Then the driver element 8 on boundary edges 64 slip past a clamping frame opening. Due to the spring force, however, the clamping frame 56 is pushed back into the first position and the boundary edges 64 wedge with the driver element 8.

A cover 66 snaps onto the rotor 52 and retains the compression spring 58 and clamping frame 56 within the insert 22.

7 shows the substructure device 10 in a side view and a sectional view. The inclined position of the clamping frame 56 can be seen here.

8 shows the substructure device 10 in an assembled state with the side facing the handle 4 .

9 12 shows the substructure device 10 from the opposite side as it faces the window frame 42. FIG. The substructure device 10 is non-rotatably connected to the window frame 42 by the cams 16 . Consequently, the latching element 30 is also off 8 rotatably arranged.

As in 10 As can be seen, the cavity 6 of the handle 4 has four latching depressions 70 on a radial inner surface 68, which are offset from one another by 90° and are uniformly distributed around the axis of rotation 62. If the handle 4 is rotated, the rotatably mounted insert 22 rotates with it and the latching webs 32 run over the radial inner surface 68. When you reach the latching depressions 70, they latch into it. Due to their radially resilient design, the latching webs 32 can also be easily released from the latching depressions 70 again.

In 11 a part of the handle 4 with the driver element 8 is shown. It can be seen here that a longitudinal side of the driver element has a projection 72 . In the orientation of the driver element 8 shown here, the projection 72 cannot be inserted into the recess 12 but abuts with an edge surface of the recess 12 . However, the recess 12 has a radial cutout 74 at one point, which allows the projection 72 to be passed through and consequently the driver element 8 to be fully inserted into the substructure device 10 . Consequently, the handle 4 can only be inserted and locked in the substructure device 10 in a single, fixed orientation. This protects against incorrect assembly.

This will in 12 shown in a slightly larger sectional view. Here the projection 72 rests on the insert 22 so that the driver element 8 does not reach the clamping frame 56 and consequently cannot be locked either. So that the clamping frame 56 in the assembly of Substructure device 10 does not have to be aligned, it has four recesses for the projection 72 to be pushed through.

Figures 13a and 13b show that in order to release the driver element 8 from the substructure device 10, the handle 4 has an opening 76 through which a tool 78 can be inserted into the handle 4 and the substructure device 10. There the clamping frame 56 can be moved from the first position in the direction of the second position, which releases the connection to the driver element 8 and consequently allows the substructure device 10 to be separated from the handle 4 .

The base 18 and the cover ring 40 are designed in such a way that they form an inclined channel 80 for the tool 78 . The tool 78 is guided from the outside under the clamping frame 56 and by turning the clamping frame is slightly raised against the spring force of the compression spring 58 and the handle 4 can be dismantled together with the driver element 8 .

Since the driver element 8 always has the projection 72 at the same point, it is ensured that a dismantling bore in the rotor 52 is always aligned with the opening 76, so that the tool 78 can always be inserted through both parts. So that the cover 66 of the insert 22 does not have to be attached in a direction-oriented manner, it has two opposite dismantling openings. Furthermore, in order to prevent incorrect alignment between a window or door gear and the handle 4, provision can be made for two opposing disassembly openings to be provided both in the lower part 18 and in the cover ring 40. In the event of an operating error, the handle 4 can consequently be rotated by at least 90° and removed again.

The invention is not limited to one of the embodiments described above, but can be modified in many ways.

All of the features and advantages resulting from the claims, the description and the drawing, including structural details, spatial arrangements and method steps, can be essential to the invention both on their own and in a wide variety of combinations.
