EP4030021B1 - Actuating handle for escutcheon-free windows and doors - Google Patents

Description

The invention relates to an operating 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 variations. They usually have an elongated driver element which can move an actuating device in a window or door sash, for example a window gear, via a handle. The driver element is often designed as a square.

To open and close the window or door, in addition to the rotational 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 such that they are connected to one another axially and in a rotationally fixed manner after assembly.

It is known to implement operating handles without rosettes on a window and door sash. 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 often achieved using a grub screw. If a lock is also provided for the operating handle in question, the grub screw is screwed in from above due to the positioning of the locking cylinder, which is visually disadvantageous. Out of EP 1 683 933 B1 an operating handle is known in which a driver element can be anchored in the handle by a locking or clamping element by inserting the driver element into the handle.

EP 1 321 605 A2 , from HOPPE AG, describes an operating handle with a handle and a locking body that is arranged in a base body of the handle.

EP 3 202 999 A1 , from HOPPE AG, describes an operating handle with a wear protection agent.

EP 3 392 435 A1 describes a mechanism in a window or door that can be operated using a handle.

An object of the invention is to create an operating handle that can be attached to a window or door sash particularly easily and preferably without visible screws, while at the same time the operating handle can be implemented without a rosette.

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

The substructure device is an operating handle for components such as windows, doors and the like, with a driver element which is connected in a rotationally fixed manner to a handle, and a substructure device for attachment to a window or door frame, the driver element being able to be brought into engagement with the substructure device has at least two cams facing away from the handle for insertion into complementary cam holes in the window or door frame, the handle has a cavity through which the driver element extends axially outwards, the substructure device has a recess shaped complementary to the driver element for inserting the driver element, and the substructure device can be inserted into the cavity, proposed. According to the invention it is provided that the actuating handle has at least one pivotally mounted, spring-loaded locking or clamping element, which can be brought into force, positive and/or frictional engagement with the driver element, and the substructure device has a rotatably mounted insert in which the locking or clamping element is arranged.

The actuating handle according to the invention can therefore be implemented without a visible screw connection and preferably without a rosette. The driver element is connected to the handle in a rotationally fixed manner. 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 necessary. At the same time, the driver element extends outwards through a cavity in the handle in order to be connected to a window or door mechanism.

The substructure device is designed to be complementary to the cavity on its peripheral surface and can therefore be completely accommodated by the cavity. When installed, the cavity is on a side facing the window or door axially limited by an opening contour. The cavity extends from the opening contour into the handle and could have a shoulder surface or another inner, axial boundary there. The substructure device is designed to accommodate the driver element and at the same time to allow the driver element to be inserted 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 mounted on the window or door, the substructure device is located completely between the opening contour and the inner boundary surface.

The substructure device is used to mechanically connect the handle to the window or door sash. It is conceivable that the substructure device enters into a screw connection with the window or door sash and by inserting 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 connected to the handle in a rotationally fixed manner, the handle is also connected to the window or door sash via the substructure device. Since the substructure device can be positioned completely in the cavity, the handle with the opening contour can close with the window or door sash directly or by forming a gap. The operating handle can therefore be implemented without a rosette, since the substructure device is not visible when the handle is installed.

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 sash through the substructure device. It is intended that the driver element protrudes through the recess in order to establish an axial connection with the substructure device. For this purpose, at least one locking or clamping element is arranged in the recess and designed to establish a connection with the driver element by inserting it. This is preferred as in EP 1 683 933 B1 described achieved by inserting the driver element into the recess and engaging there with the locking or clamping element so that they are connected to one another. Due to the resilient mounting, the locking or clamping element allows a variable orientation when inserting the driver element, so that the movement of the driver element can be followed to engage both elements in one another. At the same time, pulling out can be prevented by wedging the locking or clamping element with the driver element. Due to the arrangement of the locking or clamping element within the substructure device, it is also not necessary to provide a rosette or other elements that increase the installation space and which are located above the door or Window sashes protrude outwards. Nevertheless, a secure connection can be established between the driver element and the door or window gear.

The substructure device has at least two cams facing away from the handle for insertion into complementary cam holes in the window or door frame. The cams can be used to force the substructure device to align with the window or door sash. For this purpose, it is equipped with complementary cam holes into which the cams are inserted. By screwing the substructure device in the then specified orientation, it is held and the handle attached to the substructure device is therefore also correctly aligned for use.

The cavity of the handle could further have a radial inner surface with locking recesses, with the substructure device having at least one locking web extending in the radial direction for releasably locking into the locking recesses. The radial inner surface surrounds the cavity of the handle and allows the locking bars to noticeably engage in the locking recesses when the handle is operated. It is provided here that the locking webs are connected to the substructure device in a rotationally fixed manner, so that they always maintain their position regardless of the rotation of the handle. If the handle is rotated, the locking recesses follow the rotation and, depending on their arrangement on the radial inner surface, can lock into the locking recesses. The locking webs are preferably designed to be radially resilient, so that they not only snap into place easily, but can also be easily released from the locking recesses again. The aim is to give a user haptic feedback when a certain rotational position has been reached and at the same time to easily hold the handle in this position.

It could make sense for the substructure device to have two diametrically opposed locking webs, with the radial inner surface having at least four locking recesses evenly spaced apart from one another. The locking webs can simultaneously lock into locking recesses lying opposite one another. When using four locking recesses, locking occurs in 90° increments. A larger number of locking recesses means that the locking is significantly finer, for example in 45° increments.

It is particularly advantageously provided that the at least one locking web is arranged on a locking element which is arranged on a side of the substructure device facing the handle and functions as a mounting stop for the handle. During assembly, the handle then assumes a predetermined axial position, which results in a harmonious, rosette-free shape.

It is preferred that the locking element is designed to be axially resilient in order to exert an axial prestressing force after assembly of the actuating handle. This means that any axial play can be reduced or completely compensated for.

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

In an advantageous embodiment it is provided that the at least one locking or clamping element has a clamping frame which has an opening which is 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, resilient mounting, the clamping frame can align itself obliquely to the driver element after the driver element has been inserted - depending on the size of the opening of the driver element. Particularly 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 is reversed. The clamping frame can be designed in such a way that when the reverse force is continued to move out the driver element, the clamping frame becomes even more inclined and the two elements thereby become even more wedged into one another.

It is also advantageous 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 run 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 mutually adjacent surfaces of the driver element if it is positioned at an angle. If the clamping frame is at least largely in the second position, the driver element can be passed through. Due to the resilient mounting, the clamping frame preferably always pushes into the first position, but when the driver element is pushed through, the clamping frame is pushed towards the second position.

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

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

Fig. 1 shows an operating handle 2 for windows, doors and the like. A handle 4 is shown here, which has a cavity 6 from which a driver element 8 extends outwards. The driver element 8 is designed here as an elongated square and is glued to the handle 4 or in some other way inextricably 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 be complementary to the cavity 6, so that it can be inserted completely into the cavity 6.

Fig. 2 shows the operating handle 2, in which the substructure device 10 is completely inserted 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 thereby be connected to a window or door gear 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 figure below, the cams 16 can be inserted into corresponding cam holes in a window or door frame to fix the alignment of the substructure device 10.

Fig. 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 and has a first lateral surface 24, a second lateral surface 26 with a larger diameter and an annular shoulder surface 28 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 shoulder surface 28 rests on the side of the lower part 18 facing the cams 16. The recess 12 to which the driver element 8 is connected is located here. As a result, the lower part 22 follows the rotation of the handle 4 when fully installed.

A locking element 30 is placed on the first lateral surface 24, so that the locking element 30 and the insert 22 enclose the lower part 18. The latching element 30 has two mutually opposite latching webs 32, which are designed to be radially resilient. Furthermore, the lower part 18 has several bores 34, which allow the lower part 18 to be screwed to a window or door frame. The holes 34 are later covered by the locking element 30. To precisely connect the latching element 30 to the lower part 18, the latter has two projections 36 arranged opposite one another, which enclose corresponding indentations 38 of the latching element 30. The two elements 18 and 30 are preferably with one Press fit is formed so that the locking element 30 can be placed firmly on the lower part 18. A cover ring 40 is clicked together with the lower part 18 and holds the assembly consisting of the lower part 18 and the insert 22 together.

The locking element 30 can continue to function as an axial stop for the handle 4. In order to cushion any axial play that can arise with the proposed connection, the locking element 30 is additionally designed to be resilient in the axial direction. The locking webs 32 protrude a short distance from 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, for example, around 50N. This force cushions any axial play that may arise.

Fig. 4 shows a 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. After tightening the screws 44, the locking element 30 is placed and then the handle 4 is pushed onto the substructure device 10 to insert the driver element 8.

As mentioned above, the cams 16 can be inserted into cam holes 46 in the window frame 42. This is in Fig. 5 shown. Furthermore, receiving holes 48 for the screws 44 are shown here, as well as a receiving opening 50 for the driver element 8. The cam holes 46 and the receiving holes 48 for the screws 44 could be produced using a drilling template or drilling jig.

Fig. 6 shows the insert 22 in an exploded view. Here the orientation is reversed as in Fig. 3 chosen. The insert 22 has a rotor 52 which has the first lateral surface 24. At an inner front end there is an inclined support surface 54, onto which a clamping frame 56 is urged by means of a compression spring 58. A surface normal 60 of a plane spanned by the clamping frame 56 is therefore inclined by two spatial directions to an axis of rotation 62 of the insert 22 when the clamping frame 56 lies on the support surface 54, the axis of rotation 62 also being the longitudinal axis of the driver element 8. This is referred to above as the "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 support surface 54.

When the driver element 8 is inserted, the clamping frame 56 stands up slightly so that the surface normal 60 lies largely parallel to the axis of rotation 62. This is referred to above as the "second position". Then the driver element 8 can be attached to boundary edges 64 slide past a clamping frame opening. However, due to the spring force, the clamping frame 56 is pushed back into the first position and the boundary edges 64 become wedged with the driver element 8.

A cover 66 can be clicked onto the rotor 52 and holds the compression spring 58 and the clamping frame 56 in the insert 22.

Fig. 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.

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

Fig. 9 shows the substructure device 10 from the opposite side, as it faces the window frame 42. The substructure device 10 is connected to the window frame 42 in a rotationally fixed manner by the cams 16. Consequently, the locking element 30 is also off Fig. 8 arranged in a rotationally fixed manner.

As in Fig. 10 can be seen, the cavity 6 of the handle 4 has four locking recesses 70 on a radial inner surface 68, which are each offset by 90 ° to one another and evenly distributed around the axis of rotation 62. If the handle 4 is turned, the rotatably mounted insert 22 rotates and the locking webs 32 run over the radial inner surface 68. When they reach the locking recesses 70, they snap into place. Due to their radially resilient design, the locking webs 32 can also be easily released from the locking recesses 70.

In Fig. 11 a part of the handle 4 with the driver element 8 is shown. Here it can be seen that a long 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 rather abuts 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 completely inserted into the substructure device 10. Consequently, the handle 4 can only be inserted into the substructure device 10 and locked there in a single, fixed orientation. This protects against incorrect assembly.

This will be in Fig. 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 therefore cannot be locked. So that the clamping frame 56 during assembly of the Substructure device 10 does not have to be aligned, it has four recesses for pushing through the projection 72.

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 towards 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 lower part 18 and the cover ring 40 are designed such that they form an oblique 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 disassembly hole in the rotor 52 is always aligned with the opening 76, so that the tool 78 can always be inserted through both parts. In order not to have to attach the cover 66 of the insert 22 in a direction-oriented manner, it has two disassembly openings located opposite each other. Furthermore, in order to prevent incorrect alignment between a window or door gear and the handle 4, two disassembly openings located opposite one another can be provided in both the lower part 18 and the cover ring 40. In the event of incorrect operation, the handle 4 can therefore be rotated at least 90° and dismantled again.

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