Description

Technical Field

[0001] The utility model relates to an operating handle of a door and window structural member. Background Art

[0002] There are many variations of operating handles for operating doors and windows. The operating handle is used to operate, particularly to open, flip and close the door and window, and generally comprises a handle and a basic structural assembly that can be connected to the handle.

[0003] Typically, the operating handle also has an elongated driving element, which can move an operating device in the door or window leaf, such as a window gear, through the handle. The driving element is usually designed to be square.

[0004] In order to open and close doors and windows, in addition to the rotational movement, a tensile or compressive force must also be transmitted to the door or window leaf. For this purpose, a connection is formed between the handle and the driver element, so that they are axially and rotationally connected to each other after assembly, so that the window gear mechanism can be operated. The basic structural assembly is connected to the window frame or door frame by screws, wherein the screws engage at the position of the window gear provided for this purpose.

[0005] In the prior art, it has been proposed to install operating handles without rosettes on door and window sashes. However, this results in very limited installation space for mechanical elements between the handle and the window mechanism. Due to the principle of the window mechanism and the predetermined screw spacing, the wall thickness of the handle neck is relatively thin, so that the handle neck contour can be deformed during further processing (such as vibration grinding) after the initial shaping.

[0006] For example, EP 1 683 933 B1 relates to such an operating handle in which an entrainer element can be fixed to the handle by means of a locking or clamping element by inserting the entrainer element into the handle.

[0007] The main disadvantage of this is that the reversible fastening of the handle to the basic structural assembly or the brake-mounted connecting element of the basic structural assembly requires the use of a headless screw and a corresponding tool (such as an Allen wrench). The torsion-proof fixing of the drive element to the basic structural assembly or the handle is also usually achieved by using a headless screw. If a lock is also provided on the relevant operating handle, the headless screw must be screwed in from above due to the positioning of the lock cylinder, which is visually disadvantageous. In addition, a protective cover is used to protect the threaded connection from dirt. The protective cover must be installed on the handle through the handle, or the protective cover is already pre-installed on the handle neck in a loose and rotatable manner. Both arrangements may result in the protective cover damaging the handle, and may also damage the protective cover before or during the assembly of the handle to the structural component, and greatly increase the assembly and material costs.

[0008] In this context, the objective technical task of the present invention is to provide an improved operating handle which can be reversibly connected to the corresponding basic structural assembly particularly conveniently and quickly, in particular without the need for tools and screws, so that the connection of the operating handle can be achieved at the same time without rosettes or additional protective covers. Utility Model Content

[0009] A door and window structural member operating handle, used for reversibly connecting a basic structural assembly, comprising a driving element and a handle, wherein the driving element extends along the longitudinal axis of the basic structural assembly and is connected to the basic structural assembly in a torsionally fixed manner, wherein the basic structural assembly can be installed on a window frame or a door frame, and the handle has a handle neck, wherein the handle neck includes a cavity for accommodating the basic structural assembly, and according to the utility model, it is arranged as follows: when the handle is plugged in, the basic structural assembly can be inserted into the cavity of the handle neck along the plugging direction, wherein the basic structural assembly has a safety device, and when the handle is plugged in, the safety device acts together with the handle neck to prevent the handle from being loosened in a direction opposite to the plugging direction.

[0010] Therefore, the operating handle according to the utility model can be connected to the basic structural assembly safely and reversibly, and at the same time without a rosette. The driving element is connected to the basic structural assembly in a rotationally fixed manner. A safe and rotationally fixed connection between the handle and the basic structural assembly can be established simply by plugging the handle into the basic structural assembly along the plug-in direction and cooperating with the safety device according to the utility model with the basic structural assembly.

[0011] By means of a simple plugging movement, the handle can be plugged onto the basic structural assembly without tools and accommodates the basic structural assembly axially along the longitudinal axis, preferably almost completely, in particular completely in the cavity. As a result, the operating handle is already connected to the basic structural assembly and the driving element in a torsion-proof manner, so that the desired window mechanism can be realized. This greatly shortens the installation time. In this safety position, the handle can no longer be pulled out or removed in a direction opposite to the plugging direction, because the safety device acts together with the handle or the handle neck to prevent the handle from being pulled out along the longitudinal axis of the basic structural assembly. Therefore, the handle can be fixed to the basic structural assembly only by the action of the safety device, and the handle can be plugged into the basic structural assembly manually without tools.

[0012] The basic structural assembly is designed to accommodate the driving element in a rotationally fixed manner, while allowing the driving element to be inserted into the window frame or door frame. In this case, the driving element is preferably arranged at least partially in the basic structural assembly and protrudes axially from the basic structural assembly along the longitudinal axis of the basic structural assembly in the direction of the window frame or door frame. In the state where the operating handle is mounted on the window frame or door frame, the basic structural assembly and the driving element fixed therein in a rotationally fixed manner are located in the window frame or door frame or in the basic structural assembly, so that the basic structural assembly and the driving element are advantageously not visible from the outside.

[0013] The basic structural assembly is mainly used for the mechanical connection of the handle to the window frame or door frame and for the accommodation and installation of the safety device. More preferably, the basic structural assembly can be threadedly connected to the window frame or door frame or the window gear located therein. Since the basic structural assembly can be completely located in the cavity of the handle neck, the handle can be directly flush with the door and window contour. In this way, since the basic structural assembly is not visible when the handle is installed or connected, a screw connection without rosettes and visual interference can be more advantageously achieved.

[0014] According to a preferred embodiment of the utility model, the basic structural assembly comprises: a basic element for fixing on a window frame or a door frame, a connecting element for accommodating a driving element and a safety device, and a locking element arranged between the basic element and the connecting element, wherein the connecting element extends along the longitudinal axis of the basic structural assembly and has a third groove for accommodating and surrounding the driving element, and the third groove is designed to be complementary to the driving element. Preferably, the third groove of the connecting element extends axially to the second introduction part of the connecting element. Therefore, more advantageously, the driving element can be at least partially inserted into the connecting element, while a part of it protrudes axially from the connecting element outwardly toward the window frame or the door frame. At the same time, there is enough installation space for arranging the safety device.

[0015] According to another preferred embodiment, the third groove of the connecting element can be a square groove, wherein the driving element can be designed as a corresponding square pin. Thus, two mutually complementary shapes are formed, so that the driving element can be easily inserted into the connecting element through the third groove along the longitudinal axis of the basic structural assembly.

[0016] Preferably, the inner edge of the central square groove has a protrusion, wherein the protrusion of the inner edge comprises Zamak. When the driving element or the square pin is inserted into the connecting element through the third groove, the end edge of the square pin squeezes out the Zamak protrusion at the inner edge of the square groove, thereby forming a force fit and / or form fit and a torsion-resistant connection between the driving element and the connecting element under the action of a press fit. Zamak is inexpensive to manufacture and is particularly suitable for providing the required force fit or press fit between the elements. Therefore, it is not necessary to use headless screws or the like to fix the driving element to the handle or the basic structural assembly.

[0017] More preferably, the Zamak zinc alloy protrusion is integrally formed with the connecting element of the basic structural assembly and is made of the same material. Such a connecting element may also comprise a Zamak zinc alloy. Alternatively, the Zamak zinc alloy protrusion may be glued to the inner edge of the third groove of the connecting element. Further preferably, the basic element of the basic structural assembly may also comprise a Zamak zinc alloy. In summary, these measures greatly reduce the manufacturing costs and production difficulties, especially the Zamak zinc alloy has been proven to be suitable for providing a strong and correspondingly reliable basic structural assembly.

[0018] According to a preferred embodiment, it is provided that the square groove with the inner edge structure extends axially without passing through the entire connecting element, but is only formed along the longitudinal axis of the connecting element until the driver element can be inserted into the connecting element. Preferably, the driver element is inserted axially into the third groove of the connecting element and completely passes through the first introduction section of the connecting element, wherein the driver element is inserted into the connecting element about halfway into the second introduction section. More advantageously, this ensures that the connecting element still has enough installation space to arrange the safety device and, for example, the spring element.

[0019] According to another preferred design variant, the connecting element of the basic structural assembly has a first introduction part and a second introduction part for introducing into the cavity of the handle neck, wherein the cavity of the handle neck is provided with a first accommodating area and a second accommodating area. Preferably, the introduction part of the basic structural assembly is designed to be complementary to the cavity of the handle neck and the first accommodating area and the second accommodating area on its circumferential surface. This ensures that the basic structural assembly can be inserted into the cavity of the handle conveniently and without resistance, and the operation becomes simpler when the handle is plugged into the basic structural assembly along the plug-in direction. In addition, the basic structural assembly can be completely accommodated in the cavity of the handle neck. The cavity of the handle neck is axially limited by the opening contour facing the side of the door and window in the assembled state. The cavity extends from the opening contour to the handle neck of the handle, and can have a shoulder surface or another internal axial boundary at the handle neck.

[0020] More preferably, the first receiving area forms a first stop surface, and the second receiving area forms a second stop surface. More advantageously, an assembly stop is formed in the cavity area, thereby making the insertion of the handle simpler and generating tactile feedback when the basic structural assembly is inserted into the cavity, so as to indicate that the correct position or the end position has been reached during the assembly process.

[0021] According to another preferred embodiment, the basic element is arranged around the first introduction part of the connecting element and surrounds the first introduction part of the connecting element, wherein the basic element has a first groove for accommodating and surrounding the first introduction part of the connecting element, and the first groove is designed to be complementary to the first introduction part. The overall outer diameter of the first introduction part and the basic element arranged thereon can be larger than the second introduction part of the connecting element, wherein the second introduction part of the connecting element is first inserted into the cavity of the handle neck. Since the shape of the first accommodating area corresponds to the larger outer diameter or larger outer dimension of the basic element and the first introduction part, when the second introduction part is inserted into the first accommodating area of ​​the cavity, the overall insertion and operation of the handle and the basic structural assembly can be significantly improved.

[0022] More preferably, the first lead-in part of the connecting element is designed to be cylindrical, wherein the basic element can also be designed to be cylindrical. Therefore, before the basic structural assembly is completely inserted into the cavity, the basic element can be easily plugged into the lead-in part. Preferably, the first receiving area of ​​the cavity is also cylindrical. Preferably, an annular groove is formed at one end of the first lead-in part, wherein a snap ring is arranged in the groove of the first lead-in part in order to fix the entire basic structural assembly together. This is a particularly reliable, simple and economical connection and fixing method.

[0023] More preferably, the connecting element has a bearing surface for the locking element, wherein the bearing surface is arranged on the first introduction part and the second introduction part of the connecting element and the two parts are spaced apart from each other. As a result, the locking element can be plugged onto the bearing surface before the base element is plugged onto the first introduction part. Further preferably, the bearing surface and the contour by which the locking element can be fixed on the bearing surface are formed complementary to each other. In this way, a uniform and flat fit on the bearing surface can be ensured.

[0024] More preferably, the connecting element has a Zamak profile axially adjacent to the bearing surface, which, after the locking element is mounted on the bearing surface, extends axially in the direction of the first introduction portion and protrudes above the locking element. This makes it possible to more advantageously reduce the gap between the connecting element and the locking element. In order to compensate for the gap in the connection, when assembling the basic structural assembly, the Zamak profile can simply be pressed axially using an annular tool, so that the material is squeezed into the smallest gap between the individual elements. This makes it possible to achieve a tighter fit and minimize or completely eliminate the gap. In this case, the locking element preferably has a second groove adapted to the Zamak profile. Further preferably, the Zamak profile and the second groove of the locking element are also designed to be square. This makes it easier to connect the locking element to the connecting element. Preferably, the locking element is a locking disk made of a hardened metal plate.

[0025] Preferably, the basic element has a side opening to accommodate the spring element and the ball element. Preferably, the spring element and the ball element are inserted into the side opening of the basic element in the form of a spring-ball pair, so that the ball element is arranged on the side of the basic element away from the window frame or door frame. Thereby, the spring-ball pair can be more advantageously fixed in the side opening of the basic component, and by rotating the connecting element (via the installed handle), the ball element is pressed downward or toward the door or window frame under the elastic force of the spring element.

[0026] According to another preferred design variant, the basic element of the basic structural assembly has at least two side grooves for accommodating fixing elements, wherein the fixing elements accommodated in the side grooves of the basic element protrude axially outward and along the plug-in direction of the handle so as to be inserted into the complementary frame groove of the window frame or door frame. Preferably, the side grooves are open on the circumferential surface and arranged diametrically opposite. This makes it easier to insert the fixing elements into the side grooves. On the horizontal plane of the side grooves, the basic element preferably includes two cams away from the handle for inserting into the complementary frame grooves of the window frame or door frame. In short, this improves operation and ensures automatic pre-positioning and alignment. Due to the cams, the basic structural assembly can be aligned with the window frame or door frame. The cams are inserted into the complementary frame grooves of the window frame or door frame. By inserting the fixing elements in the side grooves, the basic structural assembly is screwed onto the window frame or the window gear on the door frame so that it is fixed and aligned, so that the handle on the basic structural assembly can also be correctly positioned and aligned for use.

[0027] In this case, the locking element can have at least two, in particular four, side grooves. Preferably, the two grooves are aligned with the side grooves of the basic element and the central longitudinal axis of the fixing element positioned therein. Thus, the fixing element, for example a screw, can be simply tightened through the groove of the locking element using a suitable tool, such as an Allen key. Preferably, the fixing element is a fixing screw with an external thread, wherein the maximum diameter of the fixing screw head is about 5.5 mm. When the basic structural assembly and the driving element are mounted on the window frame or door frame, the external thread of the fixing element is engaged in a form-fitting manner with the corresponding threaded hole of the window gear located on the window frame, so that the required window mechanism can be realized safely and effectively. The minimum outer diameter of the basic structural assembly and the theoretical inner diameter of the handle are determined by the distance between the fixing screws on the basic element. By using special screws with a screw head diameter of about 5.5 mm, handle cores with smaller handle diameters and thicker walls can be produced, especially in the Asian or Chinese markets, where the screw spacing for handles without rosettes is 20 mm. This has a positive effect on the subsequent processing steps. If the wall thickness is too thin, there is a risk of deformation of the handle, for example during vibration grinding. During vibration grinding, greater wall thicknesses can counteract this risk and the shank collar can be milled again in the interior or cavity area in a further processing step. This reduces production costs and simplifies the manufacturing process.

[0028] According to another preferred embodiment, the utility model is arranged as follows: the safety device is installed in the connecting element of the basic structural assembly, wherein the connecting element includes a fourth groove, and when the handle is not plugged into the basic structural assembly, the safety device at least partially protrudes from the basic structural assembly through the fourth groove. This measure can ensure that the safety device can be operated by the handle itself or the handle neck during the plugging process of the handle.

[0029] More preferably, the safety device is arranged on the second lead-in portion of the connecting element, wherein the connecting element has a fourth groove in the region of the second lead-in portion, through which the safety device can protrude from the basic structural assembly. Preferably, the fourth groove is substantially designed in a T-shape. This can more advantageously enable the safety device to have a wider safety end to achieve a releasable safety.

[0030] Preferably, the connecting element has a clamping element for compensating for axial and / or radial play of the handle.

[0031] According to another preferred embodiment of the utility model, it is arranged as follows: the connecting element has a fifth groove on the outer surface of the second introduction part, and a clamping element is arranged in the fifth groove for compensating for the axial clearance of the handle, wherein the clamping element includes a protrusion, which is parallel to the longitudinal axis of the basic structural assembly and protrudes longer than the axial end face end of the second introduction part of the connecting element in the direction of the handle.

[0032] More preferably, the clamping element has two clamping arms, which tightly clamp the connecting element in the area of ​​the fifth groove. The clamping arms can be designed to be perpendicular to the longitudinal axis.

[0033] It is further preferred that the clamping element comprises an annular region which forms a projection and is arranged to deform when the handle is plugged in. The annular region adjoins the projection and extends parallel to the longitudinal axis, and when the handle is plugged in, the annular region reaches an end position and presses the projection onto a corresponding stop surface of the handle, thereby compressing and squeezing the projection so that it extends radially and laterally to the longitudinal axis and is compressed in the axial direction. Preferably, the clamping element comprises a polymer material and is elastic. Preferably, the second introduction part can have a bearing surface for accommodating the clamping element, wherein the bearing surface has a projection for accommodating the annular region. The projection can preferably be cylindrical, so that it complements the annular shape, so that the clamping element can be fixed to the bearing surface together with the annular region. Preferably, a certain distance is provided between the annular region of the clamping element and the cylindrical projection, so that the annular region has sufficient deformation and freedom of movement.

[0034] When the handle reaches the end position during the plugging process and the bearing surface of the connecting element abuts the first stop surface of the cavity, a certain gap is preferably provided between the safety device and the handle neck. This advantageously ensures that when the handle is plugged in, after the safety device has been moved in the direction of the longitudinal axis, it can be sufficiently firmly embedded in the undercut or similar structure and thus move back to its initial position. This results in an axial gap in the handle. The above-mentioned plastic clamping element can buffer this gap. In the last millimeter of travel to reach the second stop surface in the cavity and when reaching the end position, the handle deforms the annular area and the projection of the clamping element. Preferably, the design of the clamping arm ensures that the clamping element fits firmly with the connecting element, but at the same time leaves enough room for the annular deformation area to deform freely after the handle is plugged in and pressed. Preferably, the projection comprises a reduced end surface surface, which is formed by a lateral bevel and is formed from above. This can concentrate the load on the reduced surface and increase the surface pressure. The bevel ensures a uniform transmission of forces and stresses, so that the clamping element deforms uniformly in the annular area.

[0035] According to another preferred embodiment, an undercut is formed in the cavity of the handle neck, the safety device is engaged in the undercut and the handle is detachably connected to the basic structural assembly in the undercut, wherein when the handle is plugged in along the plug-in direction, the handle neck presses the safety device in the longitudinal axis direction until the safety device reaches the undercut position of the cavity, whereby the safety device can be moved back to its initial position. Preferably, the safety device can be pressed into its initial position by a spring force. The undercut can provide a contact surface or a receiving surface between the handle (handle neck) and the safety device. The undercut can preferably clamp the safety device in the engagement area and has a corresponding shape. In this way, the handle is effectively fixed and cannot move relative to the basic structural assembly and cannot be pulled out again.

[0036] More preferably, the cavity of the handle neck and the undercut in the cavity of the handle neck are preferably formed by machining. Further preferably, the cavity of the handle neck and the undercut in the cavity of the handle neck are formed by milling. By milling the inner contour of the handle and the undercut, the gap between the handle and the connecting element can be minimized. If an injection molding process is used, such as a "gravity molded" inner contour, the gap will be too large, in which case the gap can only be eliminated by a screw connection. Overall, these measures have a positive effect on production costs and time consumption. Secondary milling has proven to be very time-saving and labor-saving.

[0037] According to another preferred design variant of the utility model, it is provided that the safety device has at least one spring element and at least one spring-loaded safety element for detachably connecting the handle to the basic structural assembly, wherein the spring-loaded safety element is mounted so as to be movable relative to the longitudinal axis of the basic structural assembly between a release position and a safety position. As a result, the inner contour of the handle neck can squeeze the safety element protruding from the basic structural assembly into the release position along the longitudinal axis. When the undercut position in the handle neck is reached, the safety element is automatically pressed into its initial position due to the spring force and enters the safety position. Preferably, the undercut is shaped accordingly. The spring element, such as a mechanical spring, in particular a pressure spring, is suitable for moving and fixing the safety element in the safety position until the force to which the safety element is subjected is greater than the force provided by the spring element. Therefore, the movement of the safety element into the safety position caused by the spring element is reversible, so that when the safety element is moved from the safety position into the release position, the handle can be removed from the basic structural assembly.

[0038] Preferably, the safety element extends in the direction of the fourth groove of the connecting element and protrudes from the connecting element at a certain angle relative to the longitudinal axis, wherein the protruding portion of the safety element becomes larger in the plugging direction of the handle. Therefore, by plugging the handle in the plugging direction, the movement of the safety element in the longitudinal axis direction can be additionally supported, because an inclined angle is formed in the plugging direction, and a uniform movement can be achieved according to the plugging position of the handle.

[0039] In another preferred embodiment, the connecting element has a molding slope formed by a gap for accommodating and fixing the spring element in the center. The molding slope is preferably conical and extends along the longitudinal axis from the end face end of the inserted driving element to the safety element, and the safety element preferably has a part in the end face groove area of ​​the axial end face end and the second introduction part. The spring element is preferably designed as a helical spring. As a result, the spring can be axially supported on the end face end of the driving element and abut against the part of the safety element in the axial end face end area of ​​the second introduction part, so that the "conical" molding slope protrudes axially through the helical spring. In this way, the spring element can apply the required elastic force to achieve the reversible connection of the handle and the basic structural assembly. Due to the press fit and force fit and / or form fit and torsion-resistant connection between the driving element and the connecting element, although the compression spring element has an axial counterpressure, the driving element will not move, but is always firmly fixed in position.

[0040] More preferably, the safety element can be designed as a rocker, wherein the rocker comprises a polymer material and is rotatably mounted in the second introduction part of the connecting element between a release position and a fixing position. Alternatively, the safety element can also comprise a metal material, in particular a ZAMAK zinc alloy.

[0041] According to another embodiment variant, it is provided that the safety element has a safety end, wherein in the release position, the safety end of the safety element is completely accommodated in the basic structural assembly, and in the safety position, the safety end of the safety element at least partially protrudes from the basic structural assembly. When the safety end of the safety element is completely accommodated in the basic structural assembly or the connecting element in the release position, the handle can slide over the safety element so that the handle can be moved relative to the basic structural assembly and pulled out of the basic structural assembly. If the fixed end at least partially protrudes from the basic structural assembly or the connecting element, the fixed end will prevent the pull-out movement of the handle relative to the basic structural assembly, so that the handle cannot be pulled out of the basic structural assembly. Preferably, the undercut can clamp the safety end.

[0042] According to a preferred embodiment, the safety end has two shoulders, which widen the safety end relative to the connecting piece of the safety fixing element, wherein the shoulders widen the safety end radially relative to the longitudinal axis of the basic structural assembly. Due to the widened shoulders, the safety end can engage with the corresponding components, namely the handle neck and the undercut in the cavity. Through the thinner connecting piece, the safety element can be moved into the connecting element through the fourth groove. The fourth groove is preferably T-shaped, and the T-shape supports the widened shoulder shape and corresponds to it. The thinner connecting piece of the safety element extends from the end of the axial end face of the connecting element in the direction of the fourth groove of the connecting element at a certain angle relative to the longitudinal axis to the safety end.

[0043] More preferably, the spring element is axially clamped and compressed in the basic structural assembly between the securing element and the end-face end of the entrainer element, so that the spring element is configured to press the securing element and the entrainer element axially apart from each other.

[0044] According to a preferred embodiment, the utility model is arranged as follows: the safety element has at least one first axial protrusion and one second axial protrusion, and at least one radial protrusion, wherein, in the release position and the safety position, the radial protrusion abuts against the end face of the basic structural assembly away from the driving element, wherein the first axial protrusion and the second axial protrusion extend along the longitudinal axis and extend in opposite directions away from the radial protrusion. Preferably, the first axial protrusion accommodates the spring element and faces the driving element, while the second axial protrusion engages with the groove at the end of the axial end face and is arranged on the side of the safety element away from the driving element. In this way, the required spring pressure and the movement between the release position and the safety position can be achieved. Therefore, the safety element is rotatably mounted between these two positions of the second introduction part of the connecting element.

[0045] More preferably, the handle neck comprises an opening for receiving a tool, wherein the opening guides the inserted tool to the safety end of the safety element so that the safety element moves in the direction of the longitudinal axis against the spring pressure and moves from the safety position to the release position. This makes it possible to remove the handle easily and quickly. By means of the inserted tool, the safety element moves to the release position and can be pulled out of the basic structural assembly in a pulling direction opposite to the plugging direction. Reassembly can be achieved by simply plugging the handle onto the basic structural assembly. This process can be repeated an unlimited number of times, so that a reversible safety connection is always provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0117] FIG. 1 shows an operating handle 10 for a door and window structure member that can be reversibly connected to a basic structural assembly 50. The basic structural assembly 50 is Figure 2a and Figure 2b In the cross-sectional view, Figure 2c It is shown in an assembled state.

[0118] By adding Figure 3a to Figure 3d It can be seen that a driver element 15 is provided, which extends along the longitudinal axis and the rotation axis L of the basic structural component 50 and is connected to the basic structural component 50 in a rotationally fixed manner, wherein the basic structural component 50 and the driver element 15 can be connected to the window frame or door frame 19 by means of a fixing element 16 (see Figure 4c and Figures 7a to 7c ).

[0119] The operating handle 10 is plugged into a basic structural assembly 50 that is assembled and mounted on a window frame or door frame 19, and is detachably fixed to the basic structural assembly by plugging. The basic structural assembly 50 has a safety device 60, which cooperates with the handle collar 3 or the inner contour in the cavity 6 when the handle 2 is plugged in along the plugging direction A, thereby preventing the handle 2 from being loosened in the direction opposite to the plugging direction A. Figure 3a and Figure 3b The structure and arrangement of the safety device 60 according to the present invention in the basic structural assembly 50 are exemplarily described.

[0120] exist Figure 1a The operating handle generally designated as 10 in the figure has a handle 2. The handle 2 is provided with a handle neck 3 protruding along the plug-in direction A, wherein the handle neck 3 comprises a cavity 6 for accommodating a basic structural assembly 50. The cavity 6 is designed to be complementary to the outer diameter and outer dimensions of the basic structural assembly 50, so that when the handle 2 is plugged in along the plug-in direction A, the basic structural assembly 50 can be completely inserted into the cavity 6 of the handle neck 3.

[0121] The cavity 6 of the handle collar 3 is provided with a first receiving area and a second receiving area 4, 4'. The cavity 6 of the handle collar 3 is coaxial with the longitudinal axis L of the basic structural assembly 50 and is plugged into the basic structural assembly 50, and is axially limited by the opening contour on the side facing the window frame or door frame 19. The cavity 6 extends from the opening contour into the handle collar 3 of the handle 2, wherein the first receiving area 4 forms a first stop surface 5, and the second receiving area 4' forms a second stop surface 5', which play a role of installation stop during the plug-in process.

[0122] In addition, an undercut 8 is formed in the cavity 6 of the handle collar 3, and during the plugging process, the safety device 60 can engage with the undercut, so that the handle 2 can be detachably connected to the basic structural assembly 50. When the handle 2 is plugged in along the plugging direction A, the handle collar 3 presses the safety device 60 in the direction of the longitudinal axis L until the safety device 60 reaches the axial position of the undercut 8 of the cavity 6, whereby the safety device can be moved back to its initial position.

[0123] Furthermore, the collar 3 of the handle 2 further comprises an opening 7 for receiving a tool and for removing the handle 2 .

[0124] The basic structural assembly 50 is Figure 2a to Figure 2c The main structure is generally designated by 50 and comprises a base element 20 for fixing to a window frame or door frame 19 , a connecting element 40 for accommodating a driver element 15 and a safety device 60 , and a locking element 30 arranged between the base element and the connecting element 20 , 40 .

[0125] The connecting element 40 of the basic structural assembly 50 has a first and a second introduction portion 42, 42' for introduction into the cavity 6 of the handle collar 3, wherein the first and the second receiving areas 4, 4' are designed to be complementary to the introduction portions 42, 42' and the basic element 20. The connecting element 40 extends along the longitudinal axis L of the basic structural assembly 50 and comprises a third groove 41 for accommodating and enclosing the entraining element 15, the third groove being designed to be complementary to the entraining element 15. The entraining element 15 is inserted into the connecting element 40 through the third groove arranged in the first introduction portion 42. The third groove 41 is a square groove, and the entraining element 15 is a square pin, wherein the square groove partially extends axially to the second introduction portion 42' of the connecting element 40. The entraining element 15 designed as a square pin is inserted into the connecting element 40 until the inner stop point of the square groove.

[0126] As especially Figure 2c As shown, the basic element 20 is arranged around the first introduction part 42 of the connecting element 40 and surrounds the first introduction part of the connecting element, wherein the basic element 20 has a first groove 21 for accommodating and surrounding the first introduction part 42 of the connecting element 40, and the first groove is designed to be complementary to the first introduction part 42 of the connecting element 40. After the handle 2 is plugged onto the basic structural assembly 50 and completely accommodated in the cavity 6 of the handle collar 3, the first introduction part 42 and the basic element 20 plugged thereon are accommodated in the first accommodation area 4 open to the handle collar. The second introduction part 42' is arranged in the second accommodation area 4', so that the connecting element 40 is first inserted into the cavity 6 of the handle collar 3 together with the more slender second introduction part 42'. The first introduction part 42 of the connecting element 40 is designed to be cylindrical, and the basic element 20 is also designed to be cylindrical and annular, so the first groove 21 of the basic element 20 corresponds to the cylindrical shape of the first introduction part 42. The first accommodation area 4 of the cavity 6 in the handle collar 3 is also cylindrical. An annular groove 43 is formed on the end face of the first introduction portion 42 , wherein the clamping ring 11 is positioned in the groove 43 of the first introduction portion 42 for fixing all the individual components of the basic structural assembly 50 together.

[0127] The connecting element 40 has a bearing surface 45 for the locking element 30, wherein the bearing surface 45 is arranged between the first and second introduction sections 42, 42' of the connecting element 40 and the two sections are spaced apart from each other. As a result, the locking element 30 can be plugged onto the bearing surface 45 before the base element 20 is plugged onto the first introduction section 42. The bearing surface 45 and the contour, by means of which the locking element 30 is mounted on the bearing surface 45, are formed complementary to each other. The connecting element 40 has a zamak profile 44 axially adjacent to the bearing surface 45, which, after the locking element 30 is mounted on the bearing surface 45, projects axially in the direction of the first introduction section 42 and protrudes above the locking element 30. In order to compensate for the gap between the connecting element 40 and the locking element 30, the zamak profile 44 can be simply pressed axially using an annular tool when assembling the basic assembly 50, so that the material is squeezed into the smallest gap between the individual elements. The zamak profile 44 is designed to be square. To accommodate this contour, the locking element 30 comprises a square second recess 31. Figure 2d The Zamak profile 44 and the engagement between the locking element and the connecting elements 30, 40 can be seen most clearly in FIG, since the base element 20 is not mounted on the first insertion section 42. The circular locking element 30 is designed as a locking disk and is made of hardened sheet metal.

[0128] The basic element 20 has two diametrically opposite side openings 24 for accommodating the ball element and the spring element 12, 13. These elements are inserted into the side openings 24 of the basic element 20 in the form of a spring-ball pair, so that the ball element 12 is arranged on the side of the basic element 20 that is away from the window frame or door frame 19. In addition, the basic element 20 of the basic structural assembly 50 has at least two lateral, circumferentially open and diametrically opposite side grooves 22 for accommodating the fixing element 16, wherein the fixing element 16 accommodated in the side groove 22 of the basic element 20 protrudes axially outward and in the plug-in direction A of the handle 2 so as to be able to engage with a complementary frame groove of the window frame or door frame 19. At the level of the side groove 22, the basic element 20 has two cams 25 away from the handle 2 for insertion into the complementary frame groove of the window frame or door frame 19.

[0129] In this case, four side grooves 32 are formed on the locking element 30. Two of the grooves 32 are aligned with the side grooves 22 of the base element 20 and the central longitudinal axis of the fixing element 16 positioned therein.

[0130] The safety device 60 is installed in the second introduction part 42' of the connecting element 40 of the basic structural assembly 50 (see Figure 3a , 3b). Therefore, in the area of ​​the second introduction part 42', the connecting element 40 has a fourth groove 46 complementary to the safety device 60, and when the handle 2 is not plugged into the basic structural assembly 50, the safety device 60 can at least partially protrude from the basic structural assembly 50 through the fourth groove. The fourth groove 46 of the second introduction part 42' is designed to be T-shaped. Figure 2d The connection element 40, in particular the second introduction part 42', is shown in a perspective view of the bottom. Figure 2d A T-shape can be seen in the figure.

[0131] In addition, the connecting element 40 has a fifth groove 47 on the outer surface of the second introduction part 42' for accommodating the clamping element 17. The clamping element 17 can be used to compensate for the axial clearance of the handle. In order to accommodate and arrange the clamping element 17, the second introduction part 42' also includes a support surface 47' and a protrusion 48, which extends vertically away from the support surface 47'. The protrusion 48 is designed to be cylindrical. In addition, the second introduction part 42' of the connecting element 40 also has an axial end face end 49, and the end face end has an end face groove 49' for at least partially supporting and accommodating the safety device 60. In particular, from Figure 2c As can be seen in the figure, in the second introduction part 42' of the connecting element 40, a gap for accommodating the spring element 62 is provided approximately at the level of the fifth groove 47. The gap forms a conical, axially extending shaped inclined surface 14, the top of which protrudes in the direction of the axial end face end 49 and the end face groove 49'. For example, the shaped inclined surface 14 can be used to accommodate the spring element or to center the spring element.

[0132] In particular, Figure 3a and Figure 3b The structure of the securing device 60 and the assembly of the securing device 60 and the entrainment element 15 in the connecting element 40 are described.

[0133] Safety device in Figure 3a and Figure 3bThe connecting element 40 is generally designated as 60 and comprises at least one spring element 62 and at least one spring-loaded safety element 61 for detachably connecting the handle 2 to the basic structural assembly 50. The spring-loaded safety element 61 is mounted in the connecting element 40 so as to be movable or rotatable between a release position and a safety position relative to the longitudinal axis and the rotation axis L of the basic structural assembly 50. The spring element 62 is a helical spring and is suitable for moving and fixing the safety element 61 in the safety position until the force to which the safety element 61 is subjected is greater than the force provided by the spring element 62. Thus, the movement of the safety element 61 into the safety position caused by the spring element 62 is reversible, so that the handle 2 can be removed from the basic structural assembly 50 when the safety element 61 is moved from the safety position to the release position. The spring element 62 is positioned in the gap provided for this purpose and is centered on the profiled bevel 14 so that the profiled bevel 14 completely passes through the spring element 62. The spring element 62 is supported on the end face end of the driving element 15 on one side and on the axial end face end 49 of the securing element 61 and the second introduction part 42' on the other side, so that it is axially compressed relative to the non-pressurized spring position. Therefore, the spring element 62 presses the securing element 61 and the driving element 15 axially apart from each other.

[0134] The inner edge of the square third groove 41 has a zamark zinc alloy protrusion 44'. When the driving element 15 is inserted into the connecting element 40 through the square third groove 41, the end face edge (square pin) of the square driving element 15 squeezes out the zamark zinc alloy protrusion 44' on the inner edge of the square third groove 41, so that under the action of the press fit, a force fit and / or form fit and a torsion-resistant connection are formed between the driving element 15 and the connecting element 40. Due to the press fit, force fit and / or form fit and torsion-resistant connection between the driving element 15 and the connecting element 40, despite the axial counterpressure of the compression spring element, the driving element 15 does not move, but is always firmly fixed in position.

[0135] The safety element 61 is designed as a rotating rocker and extends in the direction of the fourth groove 46 in the connecting element 40. The safety element 61 protrudes from the second introduction part 42' of the connecting element 40 at a certain angle relative to the longitudinal axis L, wherein the protruding part of the safety element 61 is larger in the plug-in direction A of the handle 2. Under the elastic force of the provided spring element 62, the safety element 61 is always automatically pressed into the safety position, that is, pressed outward from the basic structural assembly 50 and the connecting element 40 in the direction of the fourth groove 46 as long as there is no obstacle.

[0136] The securing element 61 has a securing end 65 , wherein in the release position the securing end 65 of the securing element 61 is completely accommodated in the basic structural assembly 50 and the connecting element 40 , so that the handle 2 can be removed or pulled out from the basic structural assembly 50 .

[0137] Especially from Figure 3c As can be seen in the figure, in the safety position, the safety end 65 at least partially protrudes from the connecting element 40 of the basic structural assembly 50. When the safety end 65 of the safety element 61 is completely accommodated in the basic structural assembly 50 or the connecting element 40 in the release position, the handle 2 can slide over the safety element 61, so that the handle 2 can be moved relative to the connecting element 40 and pulled out from the basic structural assembly 50. When the handle 2 is plugged into the basic structural assembly 50 along the plug-in direction A, the safety element 61 engages with the safety end 65 in the undercut 8 of the handle collar 3 and prevents the handle 2 from being pulled relative to the basic structural assembly 50, so that the handle 2 cannot be pulled out or removed from the basic structural assembly 50.

[0138] The safety end 65 also has two convex shoulders 64, wherein the convex shoulders 64 widen the safety end 65 relative to the connecting piece 63 of the safety element 61, and the connecting piece is protruding at a certain angle to the fourth groove 46 (see Figure 3b ). The shoulder 64 radially widens the safety end 65 relative to the longitudinal axis L of the basic structural assembly 50, so that the safety element 61 forms a shape complementary to the T-shaped fourth groove 46. The relatively slender connecting piece 63 of the safety element 61 extends from the axial end face end 49 of the connecting element 40 to the safety end 65. The connecting piece 63 is at a certain angle to the longitudinal axis L and extends along the direction of the fourth groove 46 of the connecting element 40.

[0139] In the region of the axial end face end 49 and the end face recess 49', the securing element 61 has a first axial projection 66, a second axial projection 67 and a radial projection 68, wherein the radial projection 68 always abuts against the axial end face end 49 in both the release position and the securing position. The first axial projection 66 projects in the direction of the spring element or helical spring 62 and accommodates it, while the opposite second axial projection 67 of the securing element 61 projects into the end face recess 49'. In the securing position, a line contact is formed between the securing element 61 and the axial end face end 49 of the connecting element 40 at the support edge 69, which supports a rotational or relative movement relative to the longitudinal axis L of the securing element 61. In the release position, however, there is no contact between the securing element 61 and the support edge 69.

[0140] Figure 3c and Figure 3d The fixing element 16 shown is a screw with a threaded portion, wherein the screw head has a diameter of approximately 5.5 mm. The screw or fixing element 16 is arranged parallel to the driving element 15 and also protrudes in the direction of the window frame or door frame 19. The spacing between these fixing elements 16 is approximately 20 mm.

[0141] Especially from Figure 3dIt can be seen in FIG. 1 that the base element 20 has a stop 23 against which the screw heads of the fixing elements 16 or screws abut, so that they cannot be moved out of the base element 20 during final tightening.

[0142] like Figure 4a and Figure 4b As shown, the fastening element 16 is inserted from top to bottom parallel to the entrainer element 15 into the side recess 22 of the base element 20 .

[0143] Figure 4e Close-up and Figure 4d The front view in FIG. 3 shows that two of the four side grooves 32 of the locking element 30 are arranged coaxially with the central longitudinal axis of the side groove 22 of the base element 20 and the fixing element 16 positioned therein, while the other two side grooves 32 of the locking element 30 are arranged coaxially with the side opening 24 of the base element 20 and the spring ball pair located therein. Therefore, the fixing element 16 can be tightened through the grooves 32 of the locking element 30 using a suitable tool (such as an Allen wrench).

[0144] exist Figure 4c In the figure, the basic structural assembly 50 is installed on the window frame or door frame 19 by means of the inserted fixing element 16 and the driving element 15 connected in a rotationally fixed manner. Therefore, complementary frame grooves 19', 19" are formed on the window frame or door frame 19 for accommodating the fixing element 16 and the driving element 15. The cam 25 away from the handle at the level of the side groove 22 is engaged with the complementary frame groove 19', while the driving element 15 is engaged with the groove 19". When the basic structural assembly 50 and the driving element 15 are installed on the window frame or door frame 19, the pitch of the fixing element 16 is engaged with the corresponding threaded hole of the window gear (not shown) located on the window frame in a shape-fitting manner, so that the required window mechanism can be safely and effectively realized.

[0145] The connecting element 40 has a clamping element 17 made of plastic for compensating the axial play of the handle 2. For this purpose, the clamping element 17 has a projection 18 and is arranged in a fifth recess 47 of the second introduction part 42'. The clamping element 17 has an annular area on a bearing surface 47' provided for this purpose, wherein the annular area protrudes from a cylindrical projection 48 perpendicular to the bearing surface 47'.

[0146] Especially from Figure 3c and Figure 3d As can be seen in the figure, the projection 18 of the clamping element 17 is an extension of the annular region in the direction of the handle 2. The projection 18 extends parallel to the longitudinal axis L of the basic structural assembly 50 and protrudes longer than the axial end face end 49 of the second introduction part 42' of the connecting element 40 in the direction of the handle 2.

[0147] By increasing Figures 6a to 6c, more details of the clamping element 17 can be seen. The clamping element 17 has two clamping arms 18', which tightly clamp the connecting element 40 in the area of ​​the fifth groove 47. The clamping arms 18' are arranged perpendicular to the longitudinal axis L of the basic structural assembly 50 and have bent ends, which tightly clamp the fifth groove 47 of the connecting element 40, thereby providing a greater clamping force.

[0148] like Figure 6b In more detail, the annular region of the clamping element 17 forms a projection 18 in the direction of the handle 2. The projection 18 is configured to deform when the handle 2 is plugged in. The annular region is adjacent to the projection 18 and extends parallel to the longitudinal axis L, wherein when the handle 2 is plugged in, the annular region reaches an end position and presses the projection 18 onto the stop surface 5' of the handle 2, thereby compressing and squeezing the projection so that it extends radially and laterally toward the longitudinal axis L and is compressed axially. The clamping element 17 is made of a polymer material and has elasticity. Figure 6c As shown, a certain distance is provided between the annular region of the clamping element 17 and the cylindrical projection 48 in order to allow sufficient deformation and movement freedom for the annular region.

[0149] Figure 5a to Figure 5c The plugging process or assembly of the operating handle 10 is shown along the plugging direction A. The handle 2 is plugged onto the assembled basic assembly 50 , that is, onto the assembled basic assembly 50 with the integrated safety device 60 , the plug-in fixing element 16 and the rotationally fixed entrainment element 15 .

[0150] exist Figure 5a In the embodiment, the handle 2 is in the first starting position and is plugged into the basic structural assembly along the plugging direction A. It can be seen from the bottom of the first stop surface 5 that the edge of the first stop surface is in contact with the safety element 61. The second introduction portion 42' of the connecting element 40 is inserted into the cavity 6, while the first introduction portion 42 and the basic element 20 are still outside. Since the connecting piece 63 and the safety element 61 have inclined surfaces, the safety element 61 is squeezed along the direction of the longitudinal axis L by further plugging of the handle 2, and is pressed into the release position.

[0151] Thus, the handle 2 is in the middle position, as shown in FIG. Figure 5b As shown. The safety element 61 is completely pressed into the basic structural assembly 50 and no longer protrudes from the connecting element 40. As a result, the safety element 61 is in the released position. In the intermediate position shown, the end face of the safety end 65 is flush with the first stop face 5, so that the second introduction part 42' can be further axially inserted into the cavity 6 and the second receiving area 4'.

[0152] During the insertion process, when handle 2 reaches Figure 5cWhen the end position shown is reached and the supporting surface 45 of the connecting element 40 abuts against the first stop surface 5 of the cavity 6, some clearance is preferably provided between the lower edge of the safety end 65 and the handle neck 3 or between the inner contour of the cavity 6 and the biting edge 8. This ensures that the safety end 65 of the safety element 61 can clamp the biting edge 8 firmly enough so that it can move back to its initial position under the action of the spring force. This results in an axial clearance of the handle 2, which is buffered by the plastic clamping element 17. In the last millimeter of travel to reach the second stop surface 5' in the cavity 6 and when reaching the end position or the safety position, the handle 2 deforms the annular area and the projection 18 of the clamping element 17. As shown in FIG. Figure 5c As shown, in the safety position and the end position, the reduced surface of the projection 18 is axially pressed against the second stop surface 5'. The design of the clamping arm 18' can ensure that the clamping element 17 and the connecting element 40 are firmly matched, but at the same time, sufficient movable space is reserved for the annular deformation area of ​​the clamping element 17, so that it can be freely deformed after the handle 2 is inserted and pressed.

[0153] Figures 7a to 7c The function of the opening 7 of the handle collar 3 is schematically illustrated, which serves to receive a tool and to remove the handle 2 from the basic structural component or door or window frame 19 .

[0154] In order to disassemble the operating handle 10, a tool 70 is provided, and the tool only needs to be inserted into the opening 7. The opening 7 is configured to guide the inserted tool 70 to the safety end 65 of the safety element 61, so that the safety element 61 moves in the direction of the longitudinal axis L against the spring pressure and moves from the safety position to the release position. In this way, the handle 2 can be removed conveniently and quickly.

[0155] By means of the inserted tool 70 , the securing element 61 is moved into the release position and can be pulled out in a pull-out direction B opposite to the plug-in direction A from the basic assembly 50 and the window or door frame 19 .

[0156] Reinstallation only requires plugging the handle 2 into the basic structural assembly 50 that has been installed on the window frame or door frame 19. Such operation can be repeated indefinitely, thereby always providing a reversible safety connection mode.

[0157] The present invention is not limited to the above-described one embodiment, but can be modified in many ways.

[0158] All features and advantages in the claims, description and drawings, including design details, spatial layout and process steps, can become essential elements of the present invention alone or in multiple combinations.
