Description

Band for pivotable about a hinge axis attachment of a

Wing on a frame

The invention relates to a band for securing a wing pivotable about a hinge axis to a frame, having a wing hinge part which can be fastened to the wing and having a wing hinge part, with a frame hinge part which can be fastened to the frame and which has a frame hinge part a hinge pin defining the hinge axis, comprising at least a portion of an electrically conductive material having a front contact surface and a radial contact surface and engages both in the wing hinge part, and in the frame hinge part with an area of an electrically conductive material, with a wing contact element is in electrical contact with the region in the wing hinge part, and with a frame contact element which is in electrical contact with the region in the frame hinge part.

Such a band is known from DE 203 04 980 Ul. It serves to establish an electrical connection between a wing and a frame. As contact elements cylindrical or spherical sliding contact bodies are provided, which are arranged in aligned perpendicular to the hinge axis bores. An adjustment of the wing in the frame is not possible with the known from DE 203 04 980 Ul band. Furthermore, this tape is not suitable for outdoor use.

The invention is therefore based on the object, with regard to the upper disadvantages improved band, with the help of which an electrical contact between the sash and the frame is to produce.

This object is achieved by the reproduced in claim 1, the inventive tape.

In the band according to the invention is a first contact element of the wing contact element and the frame contact element, d. H. either the wing contact element or the frame contact element, in electrical contact with the end contact surface, whereas the second contact element of the wing contact element and the frame contact element, d. H. Accordingly, either the frame contact element or the wing contact element is in electrical contact with the radial contact surface of the hinge pin.

Due to this measure, the presence of the contact elements hinders neither an adjustment possibility in a direction perpendicular to the hinge axis, for example a Dichtungsandruckeinstellung, nor an adjustment in a direction parallel to the hinge axis, for example, for adjusting the horizontal gap dimensions of the wing in the frame.

In a preferred embodiment, the hinge pin is rotatably fixed in the wing hinge part or frame hinge part having the first contact element and can be displaced in at least one first adjustment direction perpendicular to the hinge axis. Due to the rotationally fixed arrangement, for example, in the hinge pin extending in the direction of the first adjustment direction threaded bore can be provided, from which an adjusting spindle is received, which is supported with their ends on a receptacle in the wing hinge part or the frame hinge part. In order to improve the quality of the electrical contact between the first contact element and the end contact surface, the front contact surface may-as is preferred-have a contact groove extending parallel to the first alignment direction and into which the first contact element engages.

If-as is particularly preferred-an insertion groove opening perpendicularly into this contact groove is provided, the first contact element can be brought into contact by a relative displacement perpendicular to the hinge axis, without a displacement in the direction of the hinge axis being necessary. This has the advantage that the band formed closed on the front side and thus can be particularly effectively protected against the ingress of foreign bodies.

It is furthermore preferred if the first contact element rests against the end contact surface under the effect of an elastic, for example spring-elastic force, since this again improves the quality of the electrical contacting.

In a preferred embodiment of the band according to the invention, the hinge pin is rotatably mounted in the wing hinge part or frame hinge part having the second contact element and is displaceably mounted in a second adjustment direction parallel to the hinge axis. Because of this measure, although the hinge pin rotates during a pivoting movement of the wing relative to the frame within the corresponding hinge part. This rotational movement is not hindered by the second contact element, since it rests radially. The hinge pin can also be displaced in the direction of the hinge axis without restriction by the second contact element, so that the vertical adjustability of the wing in the frame can be realized in this manner in an advantageous manner.

In a preferred structural variant, the second contact element comprises a voltage applied to the radial contact surface with a contact surface contact pin. This can-as is particularly preferred-be applied to the radial contact surface under the action of an elastic force so as to improve the quality of the electrical contact. It is particularly preferred if the contact surface of the contact pin is formed with a radius of curvature which corresponds to the radius of the hinge pin. Due to this measure the largest possible contact surface is achieved and high current densities and contact resistance, as can be expected, for example, in a punctual system are avoided.

It is particularly preferred if the first contact element forms the wing contact element and the second contact element forms the frame contact element. The adjustability in the vertical direction can then be accomplished in a manner known per se within the frame hinge part with the aid of a bearing bush, on whose upper end side the leaf hinge part is supported, and an adjusting spindle acting on its lower end side. A horizontal, for example, a Dichtungsandruckverstellung effecting adjustment can be realized in a manner known per se with the aid of a transverse to the hinge axis adjusting spindle optionally with the further use of a likewise known, provided in the receptacle of the wing hinge part for the hinge pin tooth bushing.

With a band according to the invention, a single electrical connection between a frame and a wing is preferably produced. Therefore, two tapes according to the invention are preferably needed to provide a closed circuit. One or more additional bands are also required if additional lines, for example data lines, are to be created between the wing and the frame.

The illustrated in the drawing, denoted as a whole by 100 exemplary embodiment of the tape according to the invention (hereinafter also referred to briefly as "band 100") is used to pivot about a hinge axis S attachment of a wing F to a frame R (see in particular Figs It comprises a wing hinge part 1, which has a wing hinge part 2 and a wing fastening part 3. The wing hinge part 1 furthermore has a clamping part 4, which can be screwed to the wing F with the aid of mounting screws 5 and the wing fastening part 3 If the mounting screws 5 are not completely tightened, the wing-fastening part can be secured in the clamping part 4 with the aid of an adjusting screw 6, which is stationarily mounted in the clamping part 4 and engages in a threaded bore 7 of the wing-fastening part 3 Hinge axis S vertical direction Y. This is a horizontal Justi the wing F in the frame R, for example, in order to be able to adjust the vertical gap dimensions of the wing in the frame. A cap 8 is provided with which the clamping part 4 can be covered after successful horizontal adjustment so that neither the mounting screws 5 nor the adjusting screw 6 are accessible from the outside.

In addition, the band 100 comprises a frame hinge part 9 which has a frame hinge part 10 and a frame fastening part 11 formed thereon. The latter can be screwed to the frame R by means of screws which are not shown in the drawing and pass through bores 12.

Furthermore, the band 100 comprises a hinge pin 13 which defines the hinge axis S. In the illustrated embodiment, the entire hinge pin is made of an electrically conductive material. It comprises a Stirnkontaktflä- surface 14 and a radial contact surface 15, which are electrically conductively connected to each other due to the electrical conductivity of the hinge pin. For the functionality of the band according to the invention, it would be sufficient if only one region of the hinge pin of an electrically conductive material with the front contact surface 14 and the radial contact surface 15 exist and other areas of the hinge pin would consist of a non-conductive material.

The hinge pin engages with its region of an electrically conductive material - in the illustrated embodiment, this is the entire hinge pin - both in the wing hinge part 2, as well as in the frame hinge part 10 a.

The band 100 comprises a first contact element 16, which is formed in the illustrated embodiment as a wing contact element 16 A and is in electrical contact with the end contact surface 14 of the hinge pin 13.

Furthermore, the band 100 comprises a second contact element 17, which in the illustrated embodiment forms the frame contact element 17A and is in electrical contact with the radial contact surface 15.

The hinge pin 13 is rotatably mounted in the wing hinge part 2. In its region engaging in the wing hinge part, it comprises a threaded bore 18, which extends transversely to the hinge axis S and into which an adjustment spindle 19 extends. is turned. The latter rests with its two end faces on an inner circumferential surface of a receptacle 20 of the wing hinge part 2, which surrounds the hinge pin with play. By rotary actuation of the adjusting spindle 19, the hinge pin 13 can thus be displaced perpendicular to the hinge axis. In the illustrated embodiment of the belt 100, the adjusting spindle 19 is oriented such that a rotational actuation thereof effects a sealing pressure adjustment, in other words, a displacement of the blade F perpendicular to the blade plane.

Within the wing hinge part 2 of the hinge pin 13 is surrounded by a toothed bush 21 which has an external toothing 22 which engages in a toothing 23 of the receptacle 20. This measure has the effect that the hinge bolt 13 is always aligned with respect to the hinge axis S despite the play in the receptacle 20.

The adjusting spindle 19 passes through the toothed bushing 21 in oblong holes 24, so that the toothed bushing 21 can rotate about the hinge pin 13 by an amount permitting the sealing pressure adjustment.

The first contact element 16 is designed as a contact tongue 25. It comprises a contact extension 26 extending in the direction of the hinge axis, which engages in a contact groove 27 which extends parallel to the first adjustment direction XI.

In order to be able to introduce the contact extension 26 into the contact groove 27 without displacing the contact tongue 25 parallel to the hinge axis S, an insertion groove 28 is provided, which opens perpendicularly into the contact groove 27 in the illustrated embodiment.

In order to prevent that the contact tongue 25 can lift off the end contact surface 14, a free end region 29 of the contact tongue 25 engages behind an undercut 31 formed by a cover 30 of the tooth bushing 21 (see in particular FIG. 2 a). The first contact element 16 is mounted by means of an insulating receptacle 32 in a long hole 33 of the wing hinge part 2. In the region of the insulating receptacle, the first contact element 16 is connected to an electrical line 34 which is laid in arches below the cover cap 8 so as to allow a displacement of the wing hinge part 2 and of the wing mounting part 3 in the direction Y.

The hinge bolt 13 is rotatably mounted in the frame hinge part 10 and displaceably mounted in a second adjustment direction X2 parallel to the hinge axis S. For this purpose, the hinge pin 13 is surrounded by a bearing bush 35 over part of its area, which projects into the frame hinge part 10. It comprises a flange 36, on which the wing hinge part 2 is supported. The flange 36 opposite end face 37 of the bearing bush 35 rests on a Vertikalverstellspindel 38, which is incorporated in a in the direction of the hinge axis S extending threaded hole 39 of the frame hinge part 10. By a rotary actuation of the Vertikalverstellspindel 38, the bearing bush 35 can be displaced in the direction of the hinge axis S and thus the wing hinge part 1 relative to the frame hinge part 9 for the purpose of vertical adjustment of the wing F in the frame R be relocated.

The second contact element 17 comprises a contact pin 40, which rests under a force caused by a compression spring 41 elastic force through a slot 46 in the bearing bush 35 on the radial contact surface 15 of the hinge pin 13 with a contact surface 42. The contact surface 42 has a concave curvature with a radius of curvature which corresponds to the radius of the hinge pin 13. The compression spring 41 is supported on a support element 43 provided in the frame fastening part 11. In order to prevent undesired rotation of the contact pin 40 relative to the hinge pin, the contact pin is secured against rotation in a bore 44 of the frame hinge part 10, which can be accomplished for example by a not recognizable in the drawing groove / spring guide within the bore 44.

With the exception of the contact surface 42, the second contact element 17 is coated with an insulation coating 47. The end of the contact pin facing away from the abutment surface 42 is connected to an electrical line 45, which is loosely guided in the frame R, so that it can not cause any tension or pressure on the contact pin 40.
