Description

Band to hinged about a hinge axis connecting a wing with a frame

The invention relates to a band for hinged about a hinge axis connection of a wing, a door, a window or the like with a frame, with a frame fastened to the frame hinge part, which comprises a frame attachment part and a frame hinge part, with a wing fastened to the wing hinge part, which a wing mounting part and a wing hinge part, and having a hinge pin defining the hinge axis, wherein in the frame hinge part a primary coil surrounding the hinge pin is arranged, and wherein in the wing hinge part a secondary coil surrounding the hinge pin is arranged.

Doors increasingly feature safety or comfort enhancing devices powered by electrical energy.

For power supply, these devices are either galvanic, for example via sliding contacts, or via flexible cables with an external Energy source connected, or they themselves have energy storage, such as batteries or batteries.

In the former case, there is the disadvantage that sliding contacts are susceptible to interference and cable connections significantly affect the visual appearance. In the second case, the need for separate storage increases operating costs. In addition, the space requirements of the memory can affect the functionality and visual appearance.

From DE 10 2004 017 341 A1, a band with a built-in transformer for contactless energy transmission is known. This band comprises a primary coil arranged in a frame band part and a secondary coil arranged in a leaf band part. The magnetic coupling of the secondary coil to the primary coil, which are spaced apart in the direction of the hinge axis, serves a coil passing through both hinge pin.

Although, in principle, the contactless transfer of energy from a fixed frame to a wing arranged pivotably on the frame is desirable in order to avoid the abovementioned disadvantages, experiments have shown, however, that known from DE 10 2004 017 341 A1

Band only very small electrical power from the primary to the secondary side can be transmitted because the power loss during transmission is very high.

The invention is therefore based on the object to provide a band which allows contactless transmission of higher electrical power.

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

Characterized in that the primary coil extends at least almost to the wing hinge part facing end side of the frame hinge part, that the secondary coil extends at least almost to the frame hinge part facing end side of the wing hinge part, and that between the hinge pin and the coils comprising a ferritic material Tape bolt sleeve is provided, which extends approximately over the length of the hinge pin, which is surrounded by the primary and secondary coil, surprisingly, the power loss can be significantly reduced so that higher electrical power can be transmitted in comparison to the prior art band. In addition, the band according to the invention has the advantage that any materials which have the mechanical properties required for the respective application can be used for the hinge pin, since the magnetic coupling takes place via the hinge pin sleeve and the hinge pin thus has mechanical significance in the first place , In order to keep the power loss as low as possible, on the one hand the smallest possible distance between the facing end faces of the primary and the secondary coil is required, on the other hand, the hinge pin sleeve extend as possible over the length of the hinge pin, which is surrounded by the primary and secondary coils, however, do not exceed this length as far as possible. In other words, the hinge pin sleeve is not or only slightly protrude from the opposite end faces of the primary and secondary coils.

The hinge pin sleeve preferably comprises a ferrite sleeve, which may be made of a sintered material. Such ferritic material is for

Effecting the best possible coupling of the secondary coil to the primary coil particularly well suited.

In order for the wing and frame hinge parts to pivot as little as possible, preferably almost no mechanical forces acting on the hinge pin sleeve relative to one another about the hinge axis when opening or closing the wing, the hinge pin sleeve preferably comprises an inner sliding layer which forms its inner circumferential surface and with which it rests at least substantially free of play on the hinge pin. As a result of this measure, the hinge pin sleeve and the hinge pin can rotate about the hinge axis at least virtually without friction relative to each other. Due to the almost complete freedom from play, the overall diameter of the hinge pin sleeve is minimized, so that the space required for them is also minimized. Very particular preference is given to a further development of the band according to the invention, in which the inner sliding layer is formed by an inner band pin sliding sleeve, which comprises a sliding material exhibiting plastic material. These are plastics based on POM (polyoxymethylene or polyacetal), for example, modified by plain bearings

Additives made of PTFE or chalk, which can also be processed into sleeves with very small wall thicknesses down to less than a tenth of a millimeter.

In order to further improve the magnetic coupling of the secondary coil to the primary coil, the plastic material may comprise particles of ferromagnetic material. Experiments have shown that up to 50 vol.% Ferrite particles of a maximum grain size of 500 microns (sieved) can be added to a POM-based plastic material, provided that the maximum grain size is smaller than the wall thickness of the hinge pin sliding sleeve. Preferably, however, the proportion of ferrite particles is about 25 vol.% Or less with a maximum grain size of 10 .mu.m, since the sliding properties of this plastic material will not degrade even in the case of low wall thicknesses of the hinge pin sliding sleeve in a way that is unacceptable for this application.

In order to reduce the risk of forces being transmitted to the bobbin when the frame and wing hinge parts are pivoted about the hinge axis, in a particularly preferred embodiment, the hinge pin sleeve comprises an outer sliding layer which forms its outer jacket surface.

The outer sliding layer may be formed by an outer hinge pin sliding sleeve comprising a sliding properties plastic material, for example based on POM.

As in the case of the inner hinge pin sliding sleeve particles of ferritic material in the above-mentioned proportion and with the above-mentioned grain size can be added to the plastic material, so as to further improve the magnetic coupling of the secondary coil to the primary coil. The above-described construction of the hinge pin sleeve with inner hinge pin sliding sleeve, ferrite sleeve and outer hinge pin sliding sleeve, wherein the hinge pin slip sleeves contain ferrite particles, leads to a particularly low power loss of the strip according to the invention. In particular, however, if only lower electrical powers are to be transmitted, it may be sufficient for magnetic coupling to produce the hinge pin sleeve only from a plastic material described above with a corresponding ferrite content.

In a further preferred embodiment of the strip according to the invention, at least one of, preferably both primary and secondary coils has a sleeve-shaped ferrite core, which-particularly preferably-consists of a sintered material. This ferrite core may have, at its two end-side ends formed, radially projecting collar, between which preferably the coil winding extends. On the one hand, the two collars reliably prevent the coil windings from rubbing against each other during a relative movement of the primary coil and the secondary coil, which would lead to almost immediate destruction of the coils, and the magnetic coupling of the two coils facing one another through these collars Improved end faces.

In order to further increase the certainty that no torques are introduced into the coils during a relative movement of the frame and wing hinge parts relative to one another about the hinge axis, at least one of the, preferably both primary and secondary coils has inner sliding coil sleeves whose

Inner diameter is adapted to the outer diameter of the outer Bandbolzengleithülse, so that the sliding sleeves cooperate at least substantially without play.

Most preferably, at least one of, preferably both primary and secondary coils outer outer surfaces of the coil forming outer bobbin tubes whose outer diameter of the inner diameter of a provided in the frame hinge part and / or in the wing hinge part hinge pin receptacle in the sense of a relative movement between see the coil and the frame hinge part or the wing hinge part allowing snug fit is adjusted. By means of this measure, it is reliably avoided that electrical connections routed outwardly from the coils break off by rotation of the coil relative to the frame or wing hinge part.

In an analogous manner as the hinge pin sliding sleeves, the inner Gleitspulen- and the outer bobbin sleeve of preferably ferromagnetic particles containing plastic material, in the inner Gleitspulenhülse preferably with sliding properties, be prepared.

Surprisingly, it has been found that an electrical power sufficient for many applications can be transmitted with the aid of the band according to the invention if the coil has a coil winding of a copper material with a single wound, preferably at least two layers

Coil wire diameter between 0.03 and 0.1 mm, preferably between 0.05 and 0.07 mm in diameter. The coil is characterized by only a small thickness (with thickness is here the distance between the inner and outer surface of the coil meant), so that their space requirement is low. Thus, in many cases bands according to the invention can be produced in an external appearance which corresponds to existing, purely mechanically acting bands. Inventive tapes can thus be introduced into existing strip series. A band according to the invention whose dual function - transmission of holding forces and electrical power - from the outside regularly not be viewed, which reduces the likelihood of unwanted manipulation of third parties.

In the drawing, an embodiment of a tape according to the invention - is shown schematically. It shows:

Fig. 1 is a longitudinal section along the hinge axis of this embodiment; Fig. 2 is an enlarged view of the upper frame and the wing hinge part and

Fig. 3 is an exploded view of the same embodiment as in Figs. 1 and 2.

The designated as 100 in the drawing as a whole band is formed as a so-called three-piece band. It comprises an upper frame hinge part 1 and a lower frame hinge part 2, which are spaced apart in the longitudinal direction of a hinge axis S.

Between the upper and the lower frame hinge part 1, 2 a wing hinge part 3 is arranged.

The upper and lower frame hinge parts 1, 2 each comprise a frame hinge part 4, 4 'and a frame fastening part 5, 5'. Accordingly, the wing hinge part comprises a wing hinge part 6 and a wing attachment part 7.

The hinge axis S is defined by the frame hinge parts 4, 4 'and the wing hinge part 6 in hinge pin receivers 8, 8' and 9 passing through the hinge pin 10. The storage of the hinge pin 10 in the hinge pin receivers 8, 8 ', 9 serve bushings 11, 11' and 12 of a plastic material, for example based on POM with Gleitlagermodifizierenden additives, which has been proven for use as a bearing bush in tapes. The bushings 1 1, 1 1 ', 12 have parallel to the hinge axis S extending, radial projections 13. The diameter of the circle connecting the radial projections 13 is adapted to the inner diameter of the hinge pin receptacles 8, 8 ', 9 such that the bearing bushes 11, 11', 12 engage in the respective hinge pin receptacle without play. At the upwardly directed end of the bearing bush of the lower frame hinge part 2, at the upper end of the bearing bush 11 of the upper frame hinge part 1 and at the lower end of the bearing bush 12 of the wing hinge part 3 annular end portions 14 are integrally formed radially slightly beyond the radial Projections 13 survive. They rest in a correspondingly dimensioned radial extension 15 of the respective hinge pin receptacle 8, 8 ', 9 and thus close the hinge pin receptacles to the outside against the ingress of contaminants. In addition, the end regions 14 of the bearing bushes 11 'of the lower frame hinge part 2 and the wing hinge part 3 form supports, via which forces acting in the direction of the hinge axis are introduced from the wing hinge part 3 into the lower frame hinge part 2. Furthermore, the bearing bushes 11, 11 ', 12 inner bores 16, whose diameter is adapted to the diameter of the hinge pin 10 so that it is rotatable, but at least substantially free of play of the bushings 11, 11', 12 is added.

The lower end of the lower frame hinge part 2 forms a bearing plate 17 whose dimensions correspond to the end regions 14 and which is inserted into a radial extension 15 of the lower frame hinge part.

As can be seen in particular in Fig. 3, corresponds to the length of the bearing bush 11 'almost the length of the hinge pin receptacle 8' of the lower frame hinge part 2, whereas the bearing bushes 11, 12 are formed only about half as long as the hinge pin receptacle 8 of the upper frame hinge part

1 and the hinge pin receptacle 9 of the wing hinge part 3. In the remaining space of the hinge pin receptacles 8, 9, a primary coil 19 and a secondary coil 20 are used. The primary coil 19, which is shown in FIG. 3 in juxtaposed individual parts, and the secondary coil 20 both include an inner Gleitspulenhülse 21 a on the Gleitspulenhülse

21 located sleeve-shaped ferrite core 22, which comprises at its front ends radially projecting collar 23, 23 ', one between the collar 23, 23' wound, two-layer coil winding 24 which is shown only schematically in the drawing, and an outer bobbin 25. The outside - Diameter of the outer bobbin tube 25 is dimensioned so that the primary coil 19 is received in the hinge pin receptacle 8 of the upper frame hinge part 1, the secondary coil 20 in the hinge pin receptacle 9 of the wing hinge part in a rotationally secure fit. As can be seen in particular in FIG. 2, electrical connection cables 26, 27 are led out through access bores 28, 29 from the primary coil 19 or the secondary coil 20 to the outside for contacting an electrical power source or a consumer.

In order to improve the magnetic coupling of the secondary coil 20 to the primary coil 19, the hinge pin 10 is of the length L, which is surrounded by the primary coil 19 and the secondary coil 20 (see Fig. 2) of a hinge pin sleeve comprising a ferromagnetic material 30 surrounded. As can be seen in particular from FIG. 3, the hinge pin sleeve 30 comprises an inner

Bandbolzengleithülse 31, the inner circumferential surface has a diameter which is adapted to the outer diameter of the hinge pin 10 such that it bears against the hinge pin 10 at least substantially free of play, a ferrite sleeve 32 which surrounds the inner hinge pin and the sleeve is made of a sintered material, and an outer Bandbolzengleithülse 33 which rests against the outer surface of the ferrite sleeve 32 and the outer diameter is adapted to the inner diameter of the Gleitspulenhülse 21, which rotatably engages the outer Bandbolzengleithülse 33, but substantially backlash in the Gleitspulenhülse 21.

In order to improve the magnetic coupling of the secondary coil 20 to the primary coil 19, the inner Gleitspulenhülse 21, the outer bobbin tube 25 and the inner and outer Bandbolzengleithülsen 31, 33 made of a sliding properties having plastic material based on POM, in which ferritic particles of a grain of 10 μm (sieved) and one

Volume share of 25 percent are mixed. LIST OF REFERENCE NUMBERS
