EP2795028B1 - Device for transmitting electrical energy from a wall to a wing fixed on the wall - Google Patents

Description

The invention relates to a device for transmitting electrical energy and / or electrical signals from a fixed wall to a wing hinged to the wall about a hinge axis, with a wall part fastened to the wall, with a wing part fastened to the wing, with an energy - And / or signal transmitter, which comprises a wall transmitter part provided in the hinge part and a wing transmitter part provided in the wing, at least one of the wall or wing transmitter parts being arranged displaceably in the direction of the hinge axis.

Hinges that serve to connect a wing to a hinge on a wall have been known for a long time. They have proven themselves many times in different technical configurations and are also used for doors for objects such as houses, shops or also for escape doors.

Such doors increasingly have safety or comfort-improving devices that are operated by means of electrical energy. These devices can include sensors, for example glass break sensors, which send signals to a wall-side device, for example a burglar alarm center.

For energy and / or signal transmission, these devices are therefore regularly connected to an external energy source via flexible cables. These cable connections significantly impair the visual appearance and can be trapped between the wing and the wall, which can lead to damage or even destruction of the cables.

From the DE 39 15 812 A1 and from the DE 10 2004 017 341 A1 tapes with contactless energy and / or signal transmitters are known. These are with the DE 39 15 812 A1 designed as a concentrically arranged coils or as a cylindrical capacitor. In case of DE 10 2004 017 341 A1 The contactless energy and / or signal transmitter comprises a first coil arranged in the frame hinge part and a second coil arranged in a wing hinge part. The magnetic coupling of the two coils, which are spaced apart in the direction of the hinge axis, is provided by a band bolt passing through both coils.

In principle, contactless energy transfer from a fixed frame into a wing that can be pivoted on the frame is possible with the devices known from the above-cited publications, but tests have shown that the maximum transmissible powers are too low for many desirable fields of application, since the power loss at the transmission is very high.

From the DE 20 2008 014 318 U1 a band is known with a band bolt passing through both the wall part and the wing part. A bearing bush for the hinge pin is provided in the wall part and in the wing part. each bearing bush has an electrical coil. For the vertical adjustability of such a band, the bearing bush of the wall part is included their lower end face on a threaded spindle, which is screwed from below into a threaded hole in the wall part.

A generic device is from the WO 2011/067010 A2 known. In order to increase the power that can be transmitted, in this device the wall and wing transmitter parts, which comprise induction coil arrangements, are mounted displaceably in the wall or wing part in the direction of the hinge axis. Spring arrangements are provided both in the wall part and in the wing part, by means of which the wall and wing transmission parts are pressed against one another. This measure ensures that the facing each other The end faces of the two coils are always in direct contact. This is of particular importance since, in particular in the case of inductively acting energy and / or signal transmitters, the power loss increases sharply as the distance between the wall and wing transmitter parts increases.

However, it has been shown that it is considerably more difficult to assemble such a device, in particular when no hinge pin defining the hinge axis is provided and the device is only used to transmit electrical energy and / or electrical signals and not mechanical forces. In addition, the abutment of the wall and wing transmitter parts against one another under the spring force causes the two sides of the wing and wall transmitter parts sliding against one another to wear during the opening and closing of the wing.

The invention is therefore based on the object of improving the generic device with regard to its mountability and functionality.

This object is achieved by the device reproduced in claim 1.

The device according to the invention comprises an optionally actuatable displacement drive, by means of which the wall and / or wing transmitter part of the energy and / or signal transmitter can be displaced in the direction of the hinge axis S. Because of this configuration, the wall and / or wing transmitter parts can be brought into a position in which the device can be joined together using the displacement drive. The displacement drive prevents the transmitter parts, as in the prior art, from being displaced in an uncontrolled manner due to the spring force in the direction of the hinge axis. Rather, to assemble the device, the wall and / or wing transmitter parts can be shifted into retracted assembly positions and then, with the device assembled, can be shifted to one another with the help of the shift drive in which their mutually facing sides are at a very small but well-defined distance from one another in which the sides do not rub against each other under the action of spring elements. To those with the invention To achieve associated advantages, it is not necessary that both the wall transmitter part and the wing transmitter part of an energy and / or signal transmitter must be arranged such that they can be displaced in the direction of the hinge axis S by means of the displacement drive. Rather, it is sufficient and, because of the lower construction effort, preferred to simply connect either the wall transmitter part or the wing transmitter part to the displacement drive and to arrange the other part in a fixed manner in the respectively associated wall or wing part.

The displacement drive preferably comprises an adjusting spindle which is rotatably mounted about the hinge axis. The adjusting spindle is then preferably arranged approximately such that its axis of rotation coincides approximately with the hinge axis.

The adjusting spindle is preferably arranged stationary in the direction of the hinge axis. When actuated, it therefore does not move in relation to the wall and wing parts, but the wall and / or wing transmitter parts move in the direction of the hinge axis relative to the adjusting spindle when actuated by rotation.

For this purpose, the adjusting spindle is preferably in engagement with a spindle nut provided on or connected to the at least one wall or wing transmitter part.

The adjusting spindle can be double-acting, ie it can include a right-hand thread in one area and a left-hand thread in another area. This embodiment is particularly suitable for use in a device according to the invention, which has approximately the shape of a three-part band. Such a band has two wall parts which are spaced apart from one another in the hinge axis direction and a wing part which engages in the space between the two wall parts. Such a device is particularly suitable for receiving two transmitters, each with a wall transmitter part and a wing transmitter part. One of the transmitters can then be used to transmit electrical energy, the other transmitter can be used to transmit electrical signals. In this case, the double-acting adjusting spindle can be inside the wing part be arranged stationary in the direction of the hinge axis S and cooperate with one area with the wing transmitter part of the energy transmitter, with the other area with the wing transmitter part of the signal transmitter. A rotary actuation of the adjusting spindle then causes the two wing transmitter parts to move toward or away from one another, depending on the direction of rotation.

The adjusting spindle preferably has a device for attaching a rotary actuating tool. For this purpose, it can comprise, for example, an external toothing to which, for example, a screwdriver blade serving as a rotary actuating tool can be attached. Or there is a worm wheel in engagement with the external toothing, the axis of rotation of which runs perpendicular to the hinge axis and which itself can be rotated using a turning tool. This configuration would be characterized by a more sensitive operability.

However, it is particularly preferred if a setting wheel is provided which is connected to the spindle and has crown teeth. This crown toothing can be designed such that it can be brought into engagement, for example, with a commercially available polygonal turning tool (for example Torx®). This embodiment is characterized by a particularly sensitive adjustability, without the need for gear components provided in the device, with the exception of the adjusting wheel. In addition, no additional tool provided specifically for the rotary actuation is necessary, since the toothing is preferably adapted to a polygonal turning tool, which is required anyway for mounting the device.

It is also possible to provide a drive device which is in engagement with the crown toothing and is mounted in a spindle receptacle in which the adjusting spindle is provided. The drive device can be designed for actuation with the aid of a specific tool provided for this purpose or for manual actuation.

The drive device particularly preferably comprises a shaft with an external toothing which is in engagement with the crown toothing.

In addition, the drive device preferably has a conical surface which interacts with a locking surface provided on the spindle receptacle and ensures a captive fit in a receptacle of the drive device in the spindle receptacle.

In order to be able to permanently maintain a positioning of the transmitter parts achieved with the aid of the displacement drive, a locking element is preferably provided for optionally locking the displacement drive.

This locking element can comprise a stud screw, which can optionally be tightened against the adjusting spindle.

In principle, transformers which are technically very differently configured or operative can be used in connection with the device according to the invention. For example, it is also conceivable to use optoelectronic or capacitive transformers and to be able to position them optimally on the basis of the configuration according to the invention. In particular, however, the device according to the invention is provided for the use of induction coil arrangements in the wall and wing transmitter parts.

The wall and / or wing transmitter parts can comprise housings for shielding electrical or magnetic fields, which are open on the mutually facing sides of the wall and wing transmitter parts. So that manufacturing tolerances are automatically compensated for, the actual transmitter components can be floatingly supported in the housings, for example by a flexible layer in a gap between the transmitter component and the housing.

The device according to the invention preferably also has means for securing the wall or wing transmitter parts against rotation in the band or the Wing part on. This prevents any entrainment forces that arise between the wall and the wing transmitter parts when the wing is opened or closed, for example due to the ingress of contaminants, from tearing off any existing connection cables of the transmitter parts.

The means for securing against rotation can comprise a projection provided on the wall or wing transmission part, which protrudes into a recess provided on the wall or wing part. This recess can include boundary surfaces running approximately perpendicular to the hinge axis, which form adjustment path limitations for the wall or wing transmitter part.

The projection can have a channel for the passage of connecting cables of the wall or wing transmitter part, in order to provide particularly effective protection against damage to the connecting cable.

The embodiment of an apparatus according to the invention, designated 100 as a whole in the drawing, is modeled on a three-part band. It comprises two wall parts 1, 2 spaced apart from one another in the direction of the hinge axis S, onto which fastening parts 3, 4 are molded.

A wing part 6 is arranged in the space 5 between the two wall parts 1, 2. The wing part 6 can be pivoted about the hinge axis S. It comprises a fastening part 7, by means of which it can be fastened to a wing, not shown in the drawing.

As especially in Fig. 2 As can be seen, the device 100 comprises an energy transmitter 8, which is used in particular to transmit electrical actuating power from a wall into the wing, which is required by consumers provided on the wing to drive it. The energy transmitter 8 comprises a wall transmitter part 9 provided in the wall part 1 and a wing transmitter part 10 provided in the wing part 6. The wall and wing transmitter parts 9, 10 are designed as induction coils for mutual inductive coupling. They each comprise a soft magnetic coil body 11, 12 which completely surrounds a respective coil winding 13, 14, with the exception of the sides facing one another. Both coil formers each have a central core 15, 16, which are solid in this embodiment of the device 100. The mutually facing end faces of the coil former 11, 12 including the cores 15, 16 are flat.

With the exception of the sides facing each other, the bobbins 11, 12 and thus the actual transmitter parts 9, 10 are surrounded by housings 17, 18, which serve to shield external interference, in particular external magnetic fields in the exemplary embodiment shown. The housings 17, 18 are designed such that they overlap on the mutually facing side by integrally formed, complementary chamfers. For this purpose, the housing 17 of the wall transmitter part 9 has a radially protruding circumferential collar 19, which immediately forms a contact surface for the purpose of positioning the housing 17 in the wall part 1.

Between the housings 17, 18 and the respective bobbins 11, 12, a layer 20 of a resilient material is provided, which ensures a kind of floating mounting of the bobbins 11, 12. This ensures that the two bobbins 11, 12 align themselves in the assembled state, or at least essentially lie against one another over the entire surface.

In addition to the energy transmitter 8, the device 100 according to the invention has a signal transmitter 21, the basic structure of which corresponds to that of the energy transmitter 8. Accordingly, it also includes Wall transmitter part 22, which is provided in the second wall part 2. The wing transmitter part 23 is in turn arranged in the wing part 6, but on the side facing away from the wing transmitter part 10 of the energy transmitter 8. In order to avoid repetitions, with regard to the further structural design of the wall and wing transmitter parts 22, 23 of the signal transmitter 21 and their arrangement in the wall part 2 or the wing part 6, reference is made to the explanations for the energy transmitter 8. It goes without saying that the components of the energy transmitter 8 and those of the signal transmitter 21 can also be designed differently with regard to their electrical and electromagnetic properties and their dimensions, in order to adapt the two transmitters as best as possible to the powers or signals to be transmitted.

In order to be able to insert the wing part 6 preassembled with the wing transmission parts 10, 23 into the space 5 between the wall parts 1, 2, the wing transmission parts 10, 23 are arranged displaceably in the wing part 6 in the direction of the hinge axis S. For this purpose, recesses 24, 25 are provided in the wing part 6, which are adapted to the outer contours of the housings 17, 18 of the wing transmitter parts 10, 23 such that they are received by the recesses essentially without lateral play.

A displacement drive 26 is arranged between the two cutouts 24, 25 in the direction of the hinge axis S. It is shown in a single representation together with a turning tool intended for its actuation Fig. 5 displayed. It comprises a spindle receptacle 27 consisting, for example, of a plastic molded part, which has an opening 28 which is approximately keyhole-shaped in cross section and which extends through the in FIG Fig. 5 extends sidewall 29 facing the viewer. Furthermore, the opening 28 comprises a laterally widening, approximately slot-shaped region 30. The opening 28 serves to support an adjusting spindle 31, it comprises a central, cylindrical region 32 which is mounted within the opening 28 essentially without play. The contour of the keyhole-shaped opening 28 is adapted to the outer diameter of the area 32 such that the adjusting spindle 31 overcomes an elastic one Force can be clipped into the spindle receptacle 27 from the side wall 29 through the narrow region of the keyhole-shaped opening.

A crown wheel 39 protruding radially outward is formed on the area 32 and bears a toothing 40 which is provided for the engagement of an optionally applicable polygonal turning tool 41. In order to be able to apply this turning tool 41, a bore is provided on the spindle receptacle 27 Fig. 5 is not recognizable. A partial length of this bore is provided with an external thread, into which a stud screw 37 forming a locking element 36 can be screwed for optional locking of the adjusting spindle 31. In the fully screwed-in state, the stud 37 presses with its leading end in the screwing-in direction against the adjusting spindle 31.

Threaded areas 42, 43 adjoin area 32 of adjusting spindle 31 in the direction of axis of rotation D of adjusting spindle 31. The external thread of one thread area is designed as a right-hand thread, and the external thread of the other thread area is designed as a left-hand thread. With these threaded areas, the adjusting spindle 31 engages, as in particular in Fig. 2 is recognizable, in complementary threaded bores 44, 45, which serve as spindle nuts 34, 35, the housing of the wing transmission parts 10, 23, so that these are moved toward or away from one another by rotary actuation of the adjusting spindle, depending on the direction of rotation. In order to avoid limiting the displacement path by striking the ends of the threaded areas 42, 43 on the bobbins of the wing transmitter parts, blind bores 46, 47 are provided on the bobbins, into which parts of the threaded areas 42, 43 can protrude. Such blind bores are also provided in the bobbins of the wall transmitter parts (but here inoperative) so that the same bobbins can be used to reduce manufacturing costs.

How especially out Fig. 2 is obvious, the two wing transmitter parts 10, 23 can be moved towards each other by turning the adjusting spindle 31 with the help of a turning tool, so that they - as in Fig. 3 is shown - be moved back into the space 5 between the band parts 1, 2, so that the wing part 6 can be moved out of the space 5.

Especially in Fig. 4 . 6 and 7 it can be seen that means for securing against rotation 48 in the form of projections 49 are provided on the wing transmitter parts 10, 23. These projections 49 engage in depressions 50 in the fastening part 7, which are covered by a cover cap 53 when the device is fully assembled. This cover cap is secured using a retaining screw 51. The depressions 50 comprise boundary surfaces 54 which run approximately perpendicular to the hinge axis S and which form adjustment path limitations for the wall or wing transmitter part.

The projections 49 comprise - as in particular in FIG Fig. 7 is recognizable - in each case a channel 52 through which connecting cables of the respective wing transmitter part, which cannot be seen in the drawing, can be guided in a protected manner.

It goes without saying that the frame transmitter parts can also have appropriately designed means for securing against rotation.

Another exemplary embodiment 200 of a device according to the invention is shown in FIGS 8 and 9 shown. In order to avoid repetitions, only the differences from the exemplary embodiment 100 will be discussed below. Reference is made to the description of exemplary embodiment 100 in its entirety, provided that the explanations below do not contradict this.

In the exemplary embodiment 200, the displacement drive 126 is provided in the upper wall part 101. It comprises an adjusting spindle 131, which is screwed into a threaded receptacle 154 within the wall part 101. The adjusting spindle 131 has a central through bore 155, at the upper end of which a polygonal recess 156 is provided for attaching a turning tool.

In the direction of the hinge axis S, the wall transmitter part 109 is positively connected to the adjusting spindle 131 and is arranged displaceably in the direction of the hinge axis S within the wall part 101. By rotating the adjusting spindle 131, the wall transmitter part 109 can thus be between the in Fig. 8 shown operating position and in Fig. 9 shift illustrated assembly position, whereby an assembly and disassembly of the wing part 106 is possible in a simple manner.

Furthermore, the exemplary embodiment 200 differs from the previously described exemplary embodiment 100 in that all the coil bodies comprise a central longitudinal bore 157. A single or multi-part hinge pin 158, which aligns the transmitter parts to one another, can be inserted into this.

At the in Fig. 10 The illustrated third exemplary embodiment 300, of which only the wing part is shown in an exploded view, the displacement drive 226 in turn has a spindle receptacle 227, which can consist, for example, of a metal molded part. The spindle receptacle 227, like the spindle receptacle 27 of the exemplary embodiment 100, has an opening 228 which is approximately keyhole-shaped in cross section and which is defined by the in FIG Fig. 11 extends sidewall 229 facing away from the viewer. Furthermore, the opening 228 again comprises a laterally widening, approximately slit-shaped region 230 (see in particular Fig. 12 ,

The opening 228 serves to support the adjusting spindle 231. It comprises a central, cylindrical region 232 which is mounted within the opening 228 essentially without play.

The contour of the keyhole-shaped opening 228 is adapted to the outer diameter of the area 232 in such a way that the adjusting spindle 231 can be inserted, preferably clipped, into the spindle receptacle 227 through the narrow area of the keyhole-shaped opening from the side wall 229.

A crown wheel 239 protruding outwards is formed on the area 232 and bears a toothing 240. It is - as in particular in 12 and 13 is recognizable - provided for the engagement of a drive device 259. It comprises a cylindrical shaft 260, which comprises an external toothing 261, which is in engagement with the toothing 240 of the crown gear 239.

A head 262 adjoins the shaft 260 towards the outside, which head has a conically tapering shape towards the outside. The conical surface 263 of the head lies against a locking surface 264 of the head, so that the drive device 259, although rotatable about its longitudinal axis L, is mounted in the spindle receptacle 227 essentially without play in the direction of the longitudinal axis L.

The locking surface 264 is formed by a tab 267 provided on the lower two projections 265. The two projections 265 delimit a receiving opening 266 in which the drive device 259 is mounted. Before the spindle receptacle 227 is equipped with the drive device, the tab 267 is initially in a position projecting approximately perpendicularly from the side wall of the spindle receptacle. After the drive device has been fitted, the tab 267 is plastically bent so that it rests on the cone surface 263 of the drive device 259.

The drive device has a hexagon socket 268 for attaching a turning tool. It goes without saying that other means, such as slots, cross slots, etc., can also be used for attaching a turning tool.

Furthermore, the spindle receptacle 227 comprises a threaded bore 269 which is arranged offset to the receptacle opening 266. The threaded bore 269 serves to receive a stud screw 270 which can be rotated against the area 232 of the adjusting spindle 231 in order to lock it in a desired position against automatic rotation.

The adjusting spindle 231 engages with its threaded areas 242, 243 in bores of coil bodies 211, 212. The thread areas have opposite threads, that is, a left-hand and a right-hand thread, so that when the adjusting spindle 231 is actuated in rotation, the two coil bodies are moved away from one another or towards one another, depending on the direction of rotation.
