Window and/or door fitting

Abstract

The invention relates to a fitting (1) for actuating a mechanism in a door or window, which has a handle (10) that is rotatably supported in or on a stop element (20) about an axis of rotation (D), wherein the stop element (20) can be fastened to the door or window, a drive pin (40) for actuating the mechanism in the door or window, a coupling element (50) for coupling the handle (10) to the drive pin (40), and a blocking device (70), which blocks the actuation of the drive pin (40) about the axis of rotation (D) when in the blocking position (A), wherein the blocking device (70) can be moved to a releasing position (B) through an axial actuation of the handle from a first position to a second position along the axis of rotation (D). In order to ensure increased security against unauthorized actuation of the fitting or the mechanism connected to the fitting in the window or door, and to obtain a fitting that is easy to manipulate and inexpensive to produce, the handle (10) is decoupled from the drive pin (40) in the first position (I), wherein the blocking device (70) is then in the blocking position (A), and the coupling element (50) couples the handle (10) and the drive pin (40) in the second position, and keeps the blocking device (70) in the releasing position (B). When the second position is reached, the handle is coupled to the drive pin, and unlocks it for the actuation of the mechanism.

(16) FIG. 1 shows a partially cutaway perspective schematic illustration of an embodiment of a fitting 1, e.g. for a door panel, a window sash, etc. The elements of the fitting 1 are located along an axis of rotation D, which defines an axial direction. A radial direction runs perpendicular to the axial direction, thus perpendicular to the axis of rotation D.

(17) A handle has a neck 11 in which a handle actuator 53 is received such that it rotates conjointly therewith and is axially fixed in place. A drive pin actuator 60 is located in a receiving space 56 in the handle actuator 53, which receives a drive pin 40. The drive pin 40 passes through a stop element 20 and is connected to a mechanism, not shown, which actuates a locking mechanism in a window or a door.

(18) The drive pin actuator 60 has a second flange segment 64, which is located in front of a base insert 26 of the stop element 20 in the axial direction, inside the stop element 20 on the handle end. The drive pin actuator 60 also has a first flange segment 62 (not visible in FIG. 1), which extends into the base insert 26.

(19) The drive pin actuator 60 also has a neck section 68a, which is delimited at the handle side by a closure 68b. There is a spring 69 inside the neck section 68a, which pretensions the drive pin 40 toward the stop element 20. This is of particular advantage when the installation depth of the drive pin 40 is not known or an installation depth dictated by the door panel or the window sash has to be accommodated for.

(20) The base insert 26 of the stop element 20 also has recesses 21 for blocking elements 71 and springs 72 of a blocking device 70. The blocking elements 71 can be brought into engagement with the first flange segment 62 of the drive pin actuator 60. The function of the blocking device 70 shall be explained below in reference to FIGS. 4 and 5.

(21) Cams 27 are formed in the base insert 26, which can be brought into engagement with corresponding recesses in the window or door. The base insert 26 is tensioned against a base element 28 of the stop element 20 by a securing means (not shown).

(22) A reinforcement is located between the base element 28 and the cover plate 25, the function of which shall be explained below in reference to FIG. 7.

(23) The handle actuator 52 and the drive pin actuator 60 collectively form the coupling element 50, wherein a torque can be transferred from the handle 10 to the drive pin 40 through the coupling element 50.

(24) The handle actuator 52 and the drive pin actuator 60 can be slide axially against one another along the axis of rotation D, wherein the handle 10 can be brought by this means into a first position I and a second position II (not shown). In the first position I, the handle 10 is at a radial distance to the stop element 20 in this exemplary embodiment, which is greater than when the handle is in the second position II (not shown).

(25) The handle 10 is in the first position I when the window or door is closed. The return spring 13 located on the outside of the handle actuator 52, which engages in a receiving space 14 in the handle, tensions the handle 10 against the stop element 20 such that the handle 10 is pushed into the first position I. At the same time, the return spring 13 bears on a cover plate 25 of the receiving element, wherein the cover plate is pressed by the tension of the spring 13 against the stop element 20, in particular against the base element 28 of the stop element 20.

(26) In order to secure the handle actuator 52 in the handle neck 11, there is a fastening means 12, formed by a screw in this exemplary embodiment, which extends through a multi-sided region 54 of the handle actuator 52 at the handle side, and into the handle neck 11 of the handle 10. Alternatively, the fastening of the handle actuator 52 in the handle can also take place with a material bonded connection, e.g. using adhesive.

(27) FIG. 2 shows a perspective schematic illustration of an embodiment of a coupling element 50 for a fitting 1 with a detailed illustration of the handle actuator 52 and the drive pin actuator 60.

(28) The handle actuator 52 can be placed in the neck 11 of the handle 10, as described above, and can be secured there for conjoint rotation by a fastening means 12. For this, the handle actuator 52 also has a multi-sided region 54 at its end where the handle is. The multi-sided region 54 can engage in a corresponding recess in the handle, such that a rotation of the handle about the axis of rotation D is prevented.

(29) The handle actuator 52 also has neck section 53 that is substantially cylindrical. This neck section 53 adjoins the multi-sided region 54 toward the drive pin actuator 60. The neck section 53 is in the shape of a tube and has a receiving space 56 in which the drive pin actuator 60 can be at least partially received, for example.

(30) There is a flange segment 55 on an end of the handle actuator 52 facing the drive pin actuator 60, wherein the flange segment 55 is formed by a flange and extends radially, perpendicular to the axis of rotation D. Positioning webs 66 are located on the flange segment 55 of the handle actuator 52 on the handle side, which can engage in positioning pockets in the base element 28, as shall be explained below in reference to FIGS. 6 and 7.

(31) Actuating elements 51 and engagement elements 57 are located on the side of the handle actuator 52 facing the drive pin actuator 60. In particular, there are four engagement elements 57 on the flange segment 55 that extend along the circumference of the flange segment 55, and are spaced apart along the circumference.

(32) The engagement elements 57 extend radially outward from an inner surface of the flange segment 55 formed by the receiving space 56, although the engagement elements 57 do not extend over the entire radius of the flange segment 55.

(33) The actuating elements 51 are located on ends of the engagement elements 57 lying on the circumference, and extend to a radial outer end of the flange segment 55.

(34) The actuating elements 51 are formed integrally with the engagement elements 55 and extend circumferentially along the flange segment 55 over a smaller region than the engagement elements 51.

(35) The drive pin actuator 60 has a closure 68b on an end facing the handle actuator 52, to which a neck section 68a, a first flange segment 62 and a second flange segment 64 are adjoined in the direction of the end of the drive pin actuator 60 facing away from the handle actuator. An end surface 62b closes the drive pin actuator 60 at the end lying opposite the handle actuator 52.

(36) The neck section 68a of the drive pin actuator is substantially cylindrical and hollow on the inside, such that a drive pin receiver 67 is formed inside the neck section 68a and inside the first flange segment 62 and the second flange segment 64.

(37) The neck section 68a also has numerous slots in its outer circumference, parallel to the axis of rotation D. This is of particular advantage when the drive pin 40 has a square cross section. The edges of the drive pin can engage in the slots in the outer circumference of the neck section 68a. This saves space and results in an improved torque transfer between the drive pin actuator 60 and the drive pin 40.

(38) Latching depressions 65 are located in the second flange segment 64 along its outer circumference, the function of which shall be explained below. The first flange segment 62 has blocking recesses 61, which are arranged and dimensioned such that the actuating elements 51 can be brought into engagement with the blocking recesses 61 in a form-fitting manner.

(39) The radially outer edges of the actuating elements 61 of the handle actuator 52 complement the circumferential surface of the first flange segment 62 of the drive pin actuator 60 in the exemplary embodiment when the flange segment 55 of the handle actuator 52 is pushed into the flange segment 62 of the drive pin actuator 60.

(40) The flange segment 55 of the handle actuator 52 has an outer diameter that is smaller than or equal to the inner diameter available in the first flange segment 62 of the drive pin actuator 60.

(41) FIG. 3 shows a perspective schematic illustration of another embodiment of a coupling element 50 for a fitting 1, wherein the handle actuator 52 and the drive pin actuator 60 from FIG. 2 are shown therein.

(42) The multi-sided region 54 of the handle actuator 52 has a hole for the fastening means 12.

(43) The positioning webs 66 located on the surface of the flange segment 55 of the handle actuator 52 at the handle side can be readily seen in FIG. 3. There are three positioning webs 66 located on the flange segment 55, which extend in a Y-like configuration from the radial outer edge region of the flange segment 55 to the neck section 53 of the handle actuator 52.

(44) The drive pin actuator 60 has a surface 62a of an end surface 62b facing the stop element 20 oriented toward the handle, in which the recesses 68 are located.

(45) The recesses 68 can be brought into a form-fitting engagement with the engagement elements 57 and the actuating elements 51. The recesses exhibit a negative form of the engagement elements 57 and actuating elements 51 described above.

(46) The first flange segment 62 has a blocking recess 61 in its circumferential surface 63 in the region in which the actuating elements 51 of the handle actuator 52 engage with the first flange segment 62 of the drive pin actuator 60.

(47) When the handle actuator 52 is slid onto the neck section 68a of the drive pin actuator 60 such that the neck section 68a of the drive pin actuator 60 is pushed into the receiving space 56 of the handle actuator 52, the engagement elements 57 engage in the recesses 68. In addition, the actuating elements 51 engage with the recesses 68 and the blocking recesses 61, and the flange segment 55 of the handle actuator 52 engages with the flange segment 55 of the drive pin actuator.

(48) In the engaged position in the second position II of the handle (not shown in FIG. 3), the handle actuator 52 is connected to the drive pin actuator 60 for conjoint rotation. They are coupled to one another.

(49) The coupling element 50 couples the handle 10 to the drive pin 40 in this state. The blocking recesses 61 are also complemented in this state, such that the circumferential surface 63 of the first flange segment 62 is substantially continuous.

(50) FIGS. 4 a)-d) show perspective and partially cutaway schematic illustrations of an embodiment 50 of a fitting 1 in a blocking position A, wherein the handle 10 is in the first position I.

(51) FIG. 4 a) shows a side view of the fitting with the handle 10, the stop element 20, and the drive pin 40 with the handle in the first position I, wherein the handle 10 is at a distance to the stop element 20 along the axis of rotation D when the handle is in this first position I, which is greater than the distance when the handle is in the second position II (cf. FIG. 5a)).

(52) FIG. 4 b) shows a perspective, partial illustration of the fitting with the drive pin 40, the base insert 26 of the stop element 20, the blocking device 70, and the drive pin actuator 60.

(53) In the first position I of the handle, the handle actuator 52 is not engaged with the drive pin actuator 60, such that the handle 10 is not coupled to the drive pin 40. For this reason, the handle actuator 52 is not shown in FIGS. 4 b) and c).

(54) The blocking device 70 is in the blocking position A. The blocking elements 71 of the blocking device 70 inserted in the recesses 21 are engaged with the blocking recesses 61 in the first flange segment 62 of the drive pin actuator 60 through the tension applied to them by means of the spring 72.

(55) The blocking elements 71 are in the form of rollers guided by the boundaries of the recesses 21. An alternative embodiment of the blocking elements 71, e.g. as balls or bolts, is also a possibility.

(56) The first flange segment 62 is non-rotatably connected to the stop element 20, such that it cannot rotate about the axis of rotation D, through the engagement of the blocking elements 71 with the first flange segment 62 of the drive pin actuator 60.

(57) The drive pin 40 received in the drive pin receiver 60 is thus also non-rotatably supported in the blocking position A and the first handle position I. The drive pin 40 can also be displaced axially in the drive pin receiver 60, e.g. when there is a gap, or a spring 69 is located, in the drive pin receiver 67 between the drive pin 40 and the closure 68b.

(58) The second flange segment 64, with the latching depressions 65 located in its circumference, bears on the base insert 26 when the handle is in the first position I.

(59) FIG. 4 c) shows a section through the base insert 26, the blocking device 70, the drive pin actuator 60 in the region of the first flange segment 62, and the drive pin 40 that has been placed in the drive pin receiver 67 in the drive pin actuator 60, cut along a cutting plane perpendicular to the axis of rotation D. Furthermore, the actuating elements 51 are disengaged from the recesses 68 and the blocking recesses 61, such that the recesses 68 and the blocking recesses 61 are only partially filled through the engagement of the blocking elements 71 in the blocking position A.

(60) Furthermore, it can be clearly seen that, in the blocking position A, the blocking elements 71 of the blocking device 70 are engaged in the blocking recesses 61 in the drive pin actuator 60. The spring load to the blocking elements 71 caused by the springs 72 ensures that the blocking elements 71 are tensioned radially inward into the recesses 21 in the base insert 78, perpendicular to the axis of rotation D, thus toward the drive pin 40.

(61) FIG. 4 d) shows a perpendicular cut through the partially illustrated fitting 1. The handle actuator 52 is shown together here with the drive pin actuator 60 in the blocking position A of the blocking device 70.

(62) It is also clear in FIG. 4 d) that the blocking elements 71 of the blocking device 70 are engaged in the blocking recesses 61 of the drive pin actuator 60. In the first handle position, the handle actuator is in a plane lying above the blocking device, such that the actuating elements 51 lie outside a functional region of the blocking device.

(63) FIGS. 5 a)-d) show perspective and partially cutaway schematic illustrations of an embodiment of a fitting 1 in a releasing position B.

(64) FIG. 5 a) shows a side view of the fitting with the handle 10, the stop element 20, and the drive pin 40, with the handle in the second position II, wherein the handle 10 is at a distance to the stop element 20 along the axis of rotation D in this second position II, that is smaller than the distance when the handle is in the first position I (cf. FIG. 4 a)).

(65) FIG. 5 b) shows a perspective, partial illustration of the fitting with the drive pin 40, the base insert 26 of the stop element 20, the blocking device 70, the drive pin actuator 60 and the handle actuator 52. The handle actuator 52 is engaged with the drive pin actuator 60 in the second handle position II shown herein.

(66) The blocking device 70 is in the releasing position B. In this case, the blocking elements 71 of the blocking device 70 that are inserted in the recesses 21 are not engaged in the blocking recesses 61 in the drive pin actuator 60.

(67) The blocking elements 71 of the blocking device 70 are pushed by the actuating elements 51 of the handle actuator into the recesses 21 of the based element 28, counter to the tension of the springs 72, until the blocking elements 71 are disengaged from the blocking recesses 61.

(68) In the releasing position B, the drive pin actuator is not non-rotatably blocked by the blocking device, such that a torque can be transferred between the handle actuator 52 and the handle 10 that is connected to the handle actuator 52 for conjoint rotation, and the drive pin 40.

(69) The torque is transferred in particular via the coupling established by the coupling element 50. The coupling is obtained in particular between the handle actuator 52 and the drive pin actuator 60.

(70) FIG. 5 c) shows a section, cut along a cutting plane perpendicular to the axis of rotation D, through the base insert 26, the blocking device 70, the drive pin actuator 60 in the region of the first flange segment 62, the handle actuator in the region of the flange segment, and in particular in the region of the actuating elements 51 and the drive pin 40, which is placed in the drive pin receiver 67 of the drive pin actuator 60.

(71) It is clear here that the actuating elements 51 keep the blocking elements 71 disengaged from the blocking recesses 61 and the recesses 68. Furthermore, the engagement elements 57 are engaged in the recesses 68, such that a coupling is obtained between the handle actuator 52 and the drive pin actuator 60, in particular for a rotation about the axis of rotation D. The coupling ensures that a torque can be transferred between the drive pin actuator 60 and the handle actuator 52, wherein the coupling element 50 is oriented such that the drive pin 40 can be actuated by the handle 10 when the handle is in the second position II and the blocking device 70 is in the releasing position B.

(72) FIG. 5 d) shows a perpendicular section through the partially shown fitting 1. The handle actuator 52 is shown here with the drive pin actuator 60 and the handle actuator when the blocking device 70 is in the releasing position B.

(73) It is likewise visible in FIG. 5 d) that the blocking elements 71 of the blocking device 70 are not engaged in the blocking recesses 61 of the drive pin actuator 60. This is obtained in that the handle is moved along the axis of rotation D into the second position II in the handle actuator 52 via the axial actuation of the handle 10.

(74) When the handle is in the second position II, the handle actuator 52 is engaged with the drive pin actuator via at least the actuating elements 51, wherein the actuating elements 51 complement the circumferential surface 63 of the first flange segment 62 of the drive pin actuator. The blocking elements 71 are not engaged with the drive pin actuator, wherein the blocking elements 71 lie in the recesses 21 in the base insert 26 and are pushed against the circumferential surface 63 of the first flange segment 62 that is complemented by the actuating elements 51 due to the tension of the springs 72.

(75) FIG. 6 shows a perspective schematic exploded illustration of an embodiment of a stop element 20 with a handle actuator 53.

(76) In this illustration, actuating elements 51 and engagement elements 57, described above, can be readily seen on the end facing the stop element.

(77) The base element 28 of the stop element 20 is also shown therein. The stop element 20 contains positioning pockets 22 in the base element 28, which can be brought into engagement with the positioning webs 66 of the handle actuator 52 when the handle is in the first position I.

(78) When the handle is in the second position II, the positioning webs 66 are not engaged in the positioning pockets 22.

(79) The positioning pockets 22 have the same Y-shaped configuration to one another as the positioning webs 66 on the side of the flange segment 55 of the handle actuator 52 facing the handle 10.

(80) FIG. 7 shows a perspective schematic illustration of another embodiment of a stop element 20 with a handle actuator 53.

(81) In this drawing, the cover plate 25 of the stop element 20 is not shown, such that the reinforcement 23 lying beneath the cover plate in the stop element is visible. The reinforcement 23 has recesses lying in the region of the positioning pockets 22. The positioning pockets 22 open toward the flange segment 55 of the handle actuator 52. The handle actuator 52 is guided through a central hole in the stop element 20 and passes through the stop element 20 with the neck section 53 at the side where the handle is.

(82) The recesses 24 in the reinforcement 23 stabilize the base element 28, such that the handle actuator 52 with the positioning webs 66 is non-rotatably secured by the reinforcement against rotation about the axis of rotation D. The forces acting on the positioning webs 66 and the positioning pockets 22 when it is attempted to actuate the handle in the first position through a rotation about the axis of rotation D, are absorbed by the reinforcement, and evenly distributed to the surrounding base element 28, and lastly deflected over the entire stop element 20 with the base element 26 and the cams 27.

(83) FIG. 8 shows a cutaway schematic illustration of an embodiment of a fitting 1 with a locking device, in particular a lock 81. The lock has a closing mechanism, which pushes a bolt 82 against the cover plate 25 of the stop element 20 in the latching position, such that a movement of the handle 10 from the first position I to the second position II is prevented.

(84) FIG. 9 shows a cutaway schematic illustration of an embodiment of a fitting 1 with a locking device, in particular a locking slide 83. A bolt 84 can be actuated by the locking slide 83, which engages in the receiving space 56 in the handle actuator 52 and blocks an axial movement of the handle actuator 52 in relation to the drive pin actuator 60, or vice versa. In this manner, the handle 10 is locked in the first position I by means of the locking device 80.

(85) FIG. 10 shows a cutaway perspective schematic illustration of an embodiment of a fitting 1. In this embodiment, the handle 10 is tensioned against the stop element 20 in order to ensure that the handle is in the first position I, in that the tension is obtained via an internal spring 95 and an external spring 96. The external spring 96 is located between the handle 10 and the cover plate 25 of the stop element 20, and engages at least partially in the neck 11 of the handle 10.

(86) The drive pin actuator 60 is designed such that it has a recess in a region facing the handle, in which the internal spring 95 lies in part. The internal spring 95 is located in the receiving space 56 in the handle actuator 52, and bears on the boundary of the handle actuator 52 and/or the fastening means 12 at the handle side.

(87) The coupling is pushed apart by the internal spring 95 and the external spring 96 in an axial direction along the axis of rotation D. This tensioning is counteracted by the base element 28, against which the handle actuator 52 bears with the positioning webs 66.

(88) The positioning webs 66 allow the handle to assume the first position I when engaged with the positioning pockets 22, wherein, when the positioning webs 66 are disengaged from the positioning pockets 22, the handle is kept in the second position II.

(89) FIG. 11 shows a partially cutaway perspective schematic illustration of an embodiment of a fitting 1 with a coupling element and a blocking device 70.

(90) In this embodiment, the blocking device acts in the axial direction. The blocking element 71 is supported in this case such that it can be displaced axially in a recess 21 in the stop element 20 by the tension exerted by a spring 72.

(91) When the handle actuator is actuated axially, it can be brought into engagement with the drive pin actuator 60 via the actuating element 51, by means of which the blocking element 71 can be disengaged from the blocking recess 61 in the first flange segment 62 of the drive pin actuator 60.

(92) FIG. 12 shows a cutaway schematic illustration of an embodiment of a fitting 1 with a coupling element 50 and a blocking device 70, wherein the blocking device 70 acts in the axial direction, as described above.

(93) The coupling element 50 is shown in coupled state, i.e. the handle 10, not shown in FIG. 12, is in the second position II, and the blocking device 70 is in the releasing position B.

(94) FIG. 12 also shows a latching element 90 with a latching element spring 91, which is pretensioned against the first flange segment 62. The latching element 90 can retain the coupling element 50 in latching positions corresponding to the defined positions of the handle. In order to exit the latching positions, i.e. disengage the latching element 90 from the latching depressions 65, not shown in FIG. 12, the user must exert an increased force, wherein a feedback is generated that can be felt by the user upon reaching a latching position.

(95) FIG. 13 shows a perspective schematic illustration of an embodiment of a coupling element 50 for a fitting 1. The coupling element 50 is designed such that the neck section 68a of the drive pin actuator 60 and the receiving space 56 in the handle actuator 52 are covered over a particularly long axial length in the assembled state. This improves the guidance of the handle 10 in the fitting 1.

(96) According to this embodiment, radial outer projections 68c and radial inner projections 68c are located in the first flange segment 62 of the drive pin actuator 60, which can be brought into engagement with corresponding radial outer and radial inner recesses 59 in the handle actuator, when the handle is in the second position II.

(97) FIG. 14 shows a perspective schematic illustration of an embodiment of a coupling element 50 for a fitting 1, seen from the perspective of the stop element 20. In this perspective, the radial outer and radial inner recesses 59 of the handle actuator can be readily seen. The recesses are located in the flange region 55 of the handle actuator 52.

(98) The invention is not limited to the any of the embodiments described above, and instead can be implemented in a number of ways. As such, the coupling element 50 can have an integral design, and brought into engagement with a blocking device 70 located in the stop element 20 such that the coupling element 50 brings the blocking device 70 into engagement with the drive pin 40 in order to obtain the blocking position A, or disengages the blocking device 70 from the drive pin 40, or allows it to become disengaged therefrom, in order to obtain the releasing position B.

(99) It can also be the case that the blocking device 70 reaches the blocking position A when the handle 10 is in the second position II and the releasing position is reached when the handle is in the first position I.

(100) Furthermore, the coupling element 50 can be designed such, when it has a two-part design, that the handle actuator 52 is inserted into the drive pin actuator 60.

(101) It is clear that a fitting 1 has a handle 10 for actuating a mechanism in a door or a window, which can be rotated about an axis of rotation D, is supported on or in a stop element 20, wherein the stop element 20 can be fastened to the door or window. The fitting also has a drive pin 40 for actuating the mechanism in the door or window, a coupling element 50 for coupling the handle 10 to the drive pin 40, and a blocking device 70, which blocks actuation of the drive pin 40 about the axis of rotation D when in the blocking position A, wherein the blocking device 70 can be moved to a releasing position B by axially actuating the handle form a first position to a second position along the axis of rotation D. In order to increase security against unauthorized actuation of the fitting or the mechanism connection to the fitting in a window or door, and to obtain a fitting that is easy to manipulate and inexpensive to produce, it is provided that the handle is decoupled from the drive pin 40 in the first position, wherein the blocking device 70 is then in the blocking position A, in that the coupling element 50 couples the handle 10 to the drive pin 40 in the second position of the handle, and retains the blocking device 70 in the releasing position B. Upon reaching the second position, the handle is then coupled to the drive pin, and the mechanism can be actuated.

(102) All of the features and advantages, including structural details, spatial arrangements, and method steps, that can be derived from the claims, the description, and the drawings, can be regarded as substantial to the invention, in and of themselves or in various combinations.
