Abstract

The tape (100) has a hinge part (10) arranged in a tape receiving element (11) and tiltable about a tilting axis that is extending parallel to a hinge axis (S). The tilting axis is defined by abutment surfaces that are curved in a shape of a circle when viewed in a direction of the tilting axis. The abutment surfaces are arranged on the tape receiving element and abut against respective counter abutment surfaces arranged on a fixing member, where the counter contact surfaces are curved in an approximately complementary manner to the abutment surfaces.

Description

The invention relates to a band for pivotally about a hinge axis connection of a wing with a frame, having a first, a first fastening part and a first hinge part having hinge tabs which is pivotally connected to the hinge axis with a second fastening part and a second hinge part having second hinge tab whose second hinge part is arranged to be tiltable about a tilt axis extending approximately parallel to the hinge axis in a belt receiving element.

Such a band is for example from the DE 10 2007 019 938 B3 known. The second fastening part has, at its end remote from the second hinge part, projections which are guided in vertical slots of the tape receiving element. This guide defines the tilting axis about which the second hinge part can be tilted for the purpose of an adjustment perpendicular to the hinge axis within the tape receiving element.

The disadvantage is in the from the DE 10 2007 019 938 B3 known band that due to the ever-present game, with which the projections engage in the slots, the tilt axis is not exactly defined, whereby the achievable adjustment accuracy deteriorates. In addition, moves in an adjustment, the hinge axis on a circular arc whose radius is determined by the distance between the tilt and hinge axis, so that an adjustment is always connected by tilting the second hinge strap around the tilt axis with an unwanted displacement of the hinge axis perpendicular to the adjustment direction.

The invention has for its object to provide a respect to the aforementioned disadvantages improved band.

This object is achieved by the reproduced in claim 1 band. The tilting axis is defined in the band according to the invention of at least one in the direction of the tilting axis circular segment curved, provided on the tape receiving element contact surface, which abuts a provided on the second fastening part, approximately complementary curved counter-contact surface. Due to the flat contact an at least almost play-free mounting of the second fastening part in the tape receiving element is achieved during an adjustment process. The tilting of the second fastening part now takes place about a tilting axis which is perpendicularly spaced from the second fastening part about the radius of curvature of the contact surface. In this way, the length of the regularly undesirable, occurring perpendicular to the adjustment movement component can be reduced, so that the recoverable with the tape according to the invention alignment accuracy compared to the aforementioned prior art is improved.

In a preferred embodiment of the tape according to the invention two opposing contact surfaces having a constant distance from each other and provided on the tape receiving element two complementary to the counter-bearing surfaces contact surfaces whose distance from each other corresponds approximately to the distance of the counter-contact surfaces to each other. In other words, the systems and counter-bearing surfaces are arranged concentrically, so that the fastening part can be displaced around the tilting axis under two-sided, planar contact. This embodiment is therefore characterized by a particular lack of play.

It has been found that, with a thickness of the tape receiving element, the adjustment lengths of, which are normally considered desirable in the case of door leaves +/- 5mm from the central position still allows, in most cases, sufficient, although not complete compensation of the direction perpendicular to the adjustment movement component is achieved when the abutment and counter-abutment surfaces have radii of curvature, which cause the tilt axis is outside the second attachment part , The length of the unwanted component of motion perpendicular to the direction of adjustment can be influenced by selecting the radii of curvature.

The achievable with the tape according to the invention advantages are independent of the means which are provided for effecting the tilting movement of the second fastening part about the tilting axis. Because of the ease of manufacture and the precise operability, a particularly preferred embodiment of the tape according to the invention for this purpose an adjusting screw, which - is particularly preferred - in a threaded bore of the second fastening part is taken and is supported with its two ends to inner sides of the tape receiving element. If the thread pitches of the adjusting screw and the threaded bore are chosen to be self-locking, then no further measures are required to fix the second fastening part in an adjustment position achieved by rotary actuation of the adjusting screw, also because of the at least almost play-free mounting of the second fastening part in the band receiving element.

The adjusting screw is - particularly preferably - provided on the remote from the second hinge part end portion of the second fastening part. In other words, in this particularly preferred embodiment of the band according to the invention, the adjusting screw is not located between the bearing of the second fastening part defining the tilting axis and the second hinge part, but the bearing defining the tilting axis takes place between the adjusting screw and the second hinge part. The second attachment part is thus formed as a kind of rocker pivotable about the tilt axis, at one end of which the adjusting screw, at the other end of which the second hinge part are located. By virtue of this measure, the distance between the hinge axis and the tilting axis is reduced, so that forces absorbed by the second hinge part are introduced into the tape receiving element via a shorter lever than in the prior art.

In a very particularly preferred embodiment of the tape according to the invention, the tape receiving element is formed in a direction parallel to the tilting axis and extending parallel between the contact surfaces dividing plane. A pre-assembly of the second hinge, the adjusting screw and the tape receiving member to a module can then be done in a simple manner by first screwed the adjusting screw into the threaded bore of the second mounting part of the prefabricated second hinge strap, this inserted in a part of the tape receiving element and then mounted the other part becomes.

In a further development of the band according to the invention, the hinge axis is defined by a band pin engaging in the first and second hinge parts. This has a reduced diameter area. In at least one of the first or second hinge parts, a receptacle is provided, into which a locking element can be introduced when the wing is open, which interacts with the area of reduced diameter in the inserted state, such that the hinge pin does not work without first deploying the locking element of the first and second Hinge parts can be pulled out. A release of the connection between the first and the second hinge flap is therefore possible nondestructive only after removal of the locking element with the wing open, whereby an unauthorized "unhooking" a closed wing is much more difficult.

The above-described embodiment for securing the closed wing against unauthorized unhooking is inventive importance regardless of whether it is the tape with such a tape recording element of the type described above or a conventional tape.

The locking element is preferably designed like a forked fork in such a way that in the inserted state, the forks preferably rest against the region of reduced diameter under elastic pretensioning. Such configured locking element can be easily and inexpensively manufactured by punching from flat material, as a recording then serves a simple producible slot whose cross section is adapted to those of the locking element.

The hinge pin preferably has an external thread at one end region and a complementary internal thread as the hinge part. The hinge pin is then brought by screwing in its desired position and held in this.

In a likewise preferred embodiment of the band according to the invention an internal thread is provided on a hinge part, in which a complementary external thread having adjusting screw can be screwed. Further, an adjusting sleeve is provided, which is supported with one end on the adjusting spindle and abuts the other end to an end face of the other hinge part. By rotating the adjustment spindle, the contact surface can be displaced in the direction of the hinge axis and the belt adjusted in this direction. A circumferential collar is preferably provided on the adjusting sleeve which at least partially covers the outer circumference of the one hinge part so as to bring about an unjointed external appearance independently of the adjustment position. On the circumferential collar a projecting tab is provided with a scale on the surface thereof, by means of which the instantaneous adjustment position can be read in the direction of the hinge axis. This measure, which also has its own inventive significance in tapes of known type, makes it easier, for example, to reproduce a once found adjustment position after removal of the wing.

In particular, when the band is a so-called three-piece band, in which the first band flap comprises two first hinge parts leaving the hinge axis spaced from each other, hereinafter also referred to as "upper" and "lower" first hinge part, and which is for use is provided with approximately perpendicular hinge axis, the adjusting sleeves are preferably provided at the lower, first hinge part and at the upper, first hinge part a bearing sleeve. The latter has a peripheral collar which at least substantially corresponds to that of the adjusting sleeve.

Due to this measure, it is avoided even with a three-part band, that the respective adjustment position in the direction of the hinge axis by different gap dimensions between the end faces of the upper and lower first hinge parts and the respective facing end sides of the second hinge part is optically recognizable.

The adjusting sleeve is preferably designed such that it interacts frictionally with the lower first hinge part. By "frictionally engaged" is to be understood that they can be placed damaging over the lower first hinge part overcoming friction and also removed again, but it is stored captive on the lower first hinge part and also when pulling the hinge pin for the purpose of separation Connection between the two hinge tabs on the lower first hinge part remains.

The bearing sleeve is preferably designed such that it interacts frictionally with the hinge pin. If this is displaced upward for the purpose of releasing the connection between the two hinge lugs, then it takes the bearing sleeve with it until it bears against the lower end face of the upper, first hinge part. This increases the distance between the mutually facing end faces of the adjusting sleeve and the bearing sleeve, so that re-insertion of the second hinge part is simplified.

The band 100 according to the invention shown in the drawing serves the hinged about a hinge axis S connection of a wing 1 on a frame 2. It comprises a first hinge flap 3, which is usually - as in the embodiment shown in the drawing - provided for attachment to the frame 2 and therefore also referred to as "frame hinge tab". The attachment serve four self-tapping screws 4, which pass through the first hinge flap 3 in counterbores 5.

The first hinge flap 3 comprises a fastening part 6 of a flat material, on which two in the direction of the hinge axis S spaced apart first hinge parts 7, 7 'integrally formed by bending the material. The first hinge part 7 is also referred to as "upper first hinge part", the hinge part 7 'accordingly also with "lower first hinge part".

The strip 100 according to the invention also comprises a second hinge flap 8 which has a second fastening part 9, which in turn is formed from a flat material, and a second hinge part 10 integrally formed thereon (see in particular FIG Fig. 5 ).

The second fastening part 9 is mounted in a designated as a whole with 11 tape receiving element. It comprises a front mold part 12 which faces the viewer in the installed state and a rear mold part 13 facing away from the viewer in the mounted state and an angled cover piece 14 which shows the viewer facing side of the front mold part 12 and the narrow hinge side of the tape holding element facing the second hinge part 10 11 with the exception of counterbores 15 for the passage of fastening screws 16 and a slot 17 for the passage of the second fastening part 9 covered (see also Fig. 11 ).

The front mold part 12 of the tape receiving element 11 comprises a convex contact surface 18, the rear mold part 13 a concave bearing surface 19 which is formed concentrically to the contact surface 18 (s. Fig. 10 ).

On the second fastening part 9, a complementary contact surface 20 complementary to the concave bearing surface and a concave counter-surface 21 complementary to the convex abutment surface 18 are provided, which cooperate slidably with assembled front and rear mold parts 12, 13 (see also FIG Fig. 5 ). This defines a tilting axis K about which the second fastening part can tilt, which lies outside the second fastening part 9, depending on the radius of curvature of the convex opposing contact surface 21 (see FIG. Fig. 11 ).

A tilting movement of the second fastening part 9, the adjustment displacement perpendicular to the hinge axis S in the direction of the arrow J in Fig. 11 serves, as well as a determination of the second fastening part 9 in a desired position is an adjusting screw 22, which is provided in a complementary threaded bore 23 in a projection 24 on the side facing away from the second hinge part 10 edge of the second fastening part 9. The adjusting screw 22 is supported with its two ends on inner sides 25, 25 ', which are formed on the front and rear mold parts 12, 13.

In order to be able to apply a tool for rotational actuation to the adjusting screw 22, a through-bore 26 is provided which extends through the cover piece 14 and the front molded part 12.

As in particular from Fig. 5 As can be seen, the upper and lower narrow sides 27, 27 'are supported on upper and lower edges 28, 28' of a receiving chamber 29 formed by the front and rear mold parts 12, 13 for the second hinge part 9, so that it is in the direction of the hinge axis S fixed by the tape receiving member 11 is received.

A pre-assembly of the two mold parts 12, 13 and the Abdeckstücks 14 with the second hinge flap 8 takes place by first the front mold part 12 is placed on the Abdeckstück 14. Subsequently, the second fastening part 9 is inserted into the slot 17 of the Abdeckstücks 14 until it is with respect to the receiving chamber 29 in the desired position. Now, the adjusting screw 22 is screwed into the threaded hole 23 until it is on both sides of the Extension 24 protrudes about the same extent. Subsequently, the rear mold part 13 is placed on the second hinge plate 8 with its second fastening part 9 such that the convex counter-contact surface 20 bears against the concave contact surface 19. A fixation of the assembly takes place with the aid of a connecting screw 30, which passes through the rear molding 13 in a bore 31, the second fastening part 9 in a bore 32 and in a provided in the front mold part 12 threaded bore 33 can be screwed.

The attachment of the thus prepared assembly (in the embodiment shown in the drawing on the wing 1) by means of self-tapping screws 16th

As in particular in Fig. 4 can be seen, is used to pivot about the hinge axis S connection of the first hinge plate 3 with the second hinge flap 8, a hinge pin 34, by the first and second hinge parts 7, 7 '; 10 is inserted. For at least substantially play-free and low-friction reception of the hinge pin bearing bushes 35, 36, 37 are provided in the hinge parts.

The hinge pin has at its upper end a flat head 38 with a measure 39 for applying a turning tool. The outer diameter of the head 38 corresponds to the outer diameter of the first hinge part 7. Below the head 38, an external thread 40 is provided, which is complementary to an opening provided at the upper end of the upper first hinge part 7 internal thread 41.

For pivotal about the hinge axis S connection of the first and second hinge tabs are when the hinge pin 34, the first and second hinge parts 7, 7 '; 10 brought into a mutually aligned position, the hinge pin 34 inserted from above and finally rotatably operated until the bottom of the head 38 abuts the upper side of the upper, first hinge part 7.

In order to prevent the hinge pin 34 can be dismantled with the wing closed, it has a reduced diameter portion 42. This The area is located in the mounted state within the second hinge part 10. The latter has a slot 43 through which a clamping fork-like design locking element 44 can be inserted. It is designed such that its prongs rest under the elastic pretension on the outer circumference of the region 42.

As in Fig. 4 can be seen, the region 42 has a length which is substantially greater than the thickness of the locking element 44. This has the effect that the second hinge part 10 can be displaced in the direction of the hinge axis S between the upper and lower first hinge parts 7, 7 ', without the belt bolt 34 having to be displaced for this purpose.

For this purpose, the mutually facing sides of the upper and lower first hinge parts at a distance which is greater than the length of the second hinge part 10. For the purpose of adjustment in the direction of the hinge axis S, the bearing bush 36 of the lower first hinge part 7 'is designed as an adjusting sleeve 45, which is supported with its lower edge 46 on an adjusting spindle 47, which from below into a provided in the lower, first hinge part 7' internal thread is rotatable.

The adjusting sleeve 45 comprises at its upper end a radially projecting collar 48 whose outer diameter corresponds approximately to the outer diameter of the lower first hinge part 7 '. It carries a cap 49 whose cylindrical lateral surface 50 has an inner circumference such that the cap 49 rests against the lower first hinge part 7 'under frictional engagement.

The cap 49 has a projection 51 projecting from the circumferential collar forming a surface 51, on which a scale 52 for indicating the adjustment position in the direction of the hinge axis S is provided.

The cap 49 has downwardly directed recesses 53, which engage in complementary, provided on the collar 48 recesses 54, so as to effect a security against rotation between the cap 49 and the adjusting sleeve 45.

The provided on the upper first hinge part 7 bushing 37 has a cap 55, the outer shape of which corresponds to that of the cap 49 and the description thereof is thus made. The cap 55 comprises - as in particular in Fig. 7 is recognizable - inner projections 56, via which the cap 55 frictionally cooperates with the hinge pin 34. Due to this measure, the bearing sleeve 37 is taken up to the stop on the underside of the upper first hinge part 7 when pulling the hinge pin and so the distance between the bearing sleeves 36, 37 increases, whereby insertion of the second hinge part 10 is facilitated.

An adjustment of the second hinge strap 8 to the first hinge flap 3 in the direction of the hinge axis S can - as in particular with reference to Fig. 12a ) to c) is obvious, which show the band 100 in different adjustment positions - done by turning operation of the adjusting spindle 47.

To improve the visual impression, a threaded cap 57 is provided with an adjusting screw 47 corresponding external thread 58 which is screwed after completion of the adjustment in the lower first hinge part 7 '.
