Description

The invention relates to a band for doors, windows or the like, with at least one frame band part which can be fastened to a frame, with at least one wing band part which can be fastened to a wing, with a band bolt which at least partially passes through the frames and wing band parts in recesses defining the hinge axis at least one of the recesses provided adjusting device with which the hinge pin is displaceable parallel to itself, comprising a parallel to the hinge axis, fixed in the direction of the hinge axis, having an external screw and a screw bolt pin receiving the hinge pin.

Such a band is from the EP 860 571 A1 known. The recess has on the front side, ie on the side facing away from the wing or the frame, a central bulge running parallel to the hinge axis, in which an elongated, parallel-limited guide element is arranged. The cross section of the guide element fits exactly into the bulge, so that the guide element is guided in the bulge in a direction perpendicular to the hinge axis non-loadable, but is displaceable parallel to the hinge axis in the bulge. The guide element has a flat rear side, which rests displaceably on a flat front side of the hinge pin bushing. At the mutually facing flat surfaces an inclined guide is realized, which ensures that at a displacement of the guide element relative to the hinge pin bushing parallel to the hinge axis, which is caused by the adjusting screw forming a displacement screw, the hinge pin bushing parallel to itself perpendicular to the hinge axis moves relative to the guide element.

Although with this band, a shift of the hinge axis relative to the attachment points of the band part and thus an adjustment of the wing perpendicular to the hinge axis - also horizontal adjustment - possible, without the attachment of the band part should be solved on the wing or the frame, disadvantageous is, however, that the space requirement of the adjusting device in the band part is high, in particular due to the guide element, so that the Adjustment receiving hinge part - also called tape head - is bulky, which adversely affects the conveyed with the band optical impression and limits the capabilities of the tape. In addition, the band is due to the majority of components and the necessary for the formation of the guide surfaces in the tape head and on the guide element machining consuming in its production.

The invention is therefore based on the object, a band in which the adjustment of the hinge pin parallel to itself can be done relative to the attachment points of the tape without loosening the attachment, in other words, in which the adjustment is done within the tape head to create which is easier to manufacture and in which the space required for the adjustment is reduced.

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

In this band, the adjusting screw according to the invention in a provided in the at least one recess, in cross-section circular segment-shaped receptacle, which is aligned parallel to the hinge axis stored. Since the adjusting screw with its external thread with a provided in the hinge pin bush, in cross-section circular segment, complementary internal thread engaged, it simultaneously performs two functions, namely on the one hand a guide the hinge pin bushing parallel to the hinge axis, on the other hand - because it is fixed in the axial direction - When turning operation, a displacement of the hinge pin bushing. It is thus extended by the threaded engagement within the adjustment direction in the extended, approximately slot-shaped recess at the opposite wall of the adjusting screw, fixed in the direction of the hinge axis, however, by providing appropriate clearance angle between the hinge pin bushing and the recording in the adjustment screw around its outer periphery to be moved.

Thus, the hinge pin bushing during rotation of the adjusting screw not only in the direction of the hinge axis, but also moved transversely thereto to cause a displacement of the tape pin recorded by her parallel to itself, means for guiding the hinge pin bushing are provided in the recess, the preferably comprise a guided in a backdrop projection. For this purpose, the scenery runs transversely to the hinge axis.

It is particularly preferred to provide the projection on the hinge pin bushing and the link in the recess, as this facilitates the manufacturability of the band. Thus, in a design of the band according to the invention which is reduced to a minimum, the slotted link can be incorporated, for example, by sawing or milling an incision inclined to the hinge axis from the outside into the hinge head.

However, in order to avoid that the tape head is weakened by the incorporated backdrop and that the risk of the ingress of contaminants through the backdrop in the interior of the tape head, it is also possible to incorporate the backdrop in a definable in the recess insert.

In order to secure the hinge pin in the adjusted position, even in the case of external, dynamic loads against unintentional adjustment, in a particularly preferred embodiment of the tape according to the invention on the opposite side of the adjusting screw provided at least one opening into the recess threaded hole in which a clamping screw is provided, which fixes the belt bolt in the tightened state. This threaded screw may be formed as a grub screw, preferably with a conical end. The hinge pin may comprise a round-shaped groove adapted to the conical end, in which the grub screw engages in the screwed-in state, so as to be particularly effectively secured against unauthorized driving out. In addition, the at least one grub screw also serve to fix the insert, if available. The determination of the hinge pin in the adjustment position is especially particularly effective because the at least one clamping screw acts on the hinge pin such that the hinge pin bushing is pressed with its internal thread on the adjusting screw and this provided in the tape head receptacle, whereby on the one hand the threaded engagement between adjusting screw and hinge pin bushing and an at least almost no play, positive engagement of the tape head, adjusting screw and hinge pin bushing is guaranteed.

The adjusting screw is arranged in a particularly preferred embodiment of the tape according to the invention on the side facing away from the wing or the frame side of the recess. Thus, since the oppositely arranged, the hinge bolt securing at least one clamping screw is not accessible with the wing closed, a particularly high burglar protection is achieved with this embodiment of the tape according to the invention, without requiring special measures such as additional covers, fuses, etc.

In order to secure the adjusting screw in the direction of the hinge axis, this preferably comprises an annular groove into which engages a fixed to the tape head locking projection.

The locking projection may be integrally formed on the band in the recess. However, it is also possible to form the locking projection of a separately mountable in the recess component. This could be implemented constructively in the simple case by a screw or a rivet. However, in order to accomplish the largest possible engagement of the locking projection in the annular groove, it is particularly preferred if the component has approximately the shape of a half-ring.

Should a cap be provided, as is desirable, for example, for covering the attachment points of the band member on the wing or the frame and their outer design can be adapted to the aesthetically desirable desirable shape of the hinge part, so it is also possible, the locking projection on the form the tape head facing inside of the cap and proceed in the tape head a breakthrough, through which the component engages in the recess and in the annular groove of the adjusting screw.

For the sake of clarity, only different embodiments of the leaf hinge part of bands according to the invention are shown in the drawings, since the invention is embodied therein. It is understood that, alternatively, the frame hinge parts of the tapes according to the invention can be designed in the illustrated or in any other, previously known manner.

At the first, in Fig. 1 to 3 illustrated embodiment of the invention embodying the band member 100, which is shown here as a wing hinge part, a hinge flap 1, which has a fastening part 2 with two holes 3, which are penetrated in the assembled state of fastening screws, not shown in the drawing.

On the mounting part 2 is integrally formed a hinge part 4 - also called band head - molded. It has a recess 5 which serves to receive an adjusting device designated as a whole by 6.

The adjusting device 6, with a the hinge axis A defining hinge pin 7 parallel to itself in the direction of the double arrow P of Fig. 2 is displaceable, comprises an adjusting screw 8, which has approximately the shape of a threaded rod, in the two ends of hexagonal recesses 10 are incorporated for engagement of a rotary tool, not shown in the drawing. Further, a circumferential annular groove 11 is provided approximately in the middle of the adjusting screw, in which engages a locking projection in a manner to be described below.

The adjusting device 6 further comprises a hinge pin bushing 12 having a substantially circular outer periphery. In this outer circumference is a cross-sectionally circular segment, approximately over an angular range of 45 ° extending, complementary to the external thread of the adjusting screw 9 internal thread 13 is incorporated. On the side opposite the internal thread 13, the hinge pin bushing 12 has a flattened region 14, from which a projection 15, which is oriented obliquely to the axis of the hinge axis A, projects.

The recess 5 in the hinge part 4 is approximately oblong-shaped in cross-section, as in particular in Fig. 2 is recognizable. It points in the shorter width direction one in Fig. 2 shown above, in cross-section circular segment-shaped receptacle 16, which extends over an angular range of about 90 ° and whose radius is adapted to the radius of the adjusting screw 8 such that the adjusting screw 8 is mounted in the receptacle 16 is substantially free of play.

The adjusting screw 8 is in the axial direction by means of an approximately semi-annular member 17, which passes through an opening provided in the hinge part 4 opening 18, is held in this in the axial direction and engages in the annular groove 11, fixed.

In particular Fig. 3 can be removed, the hinge part comprises on its opposite side of the receptacle 16 a corresponding to the projection obliquely to the hinge axis A extending further opening 19 whose parallel longitudinal sides guide surfaces for the projection 15 and thus form a link 20.

In particular Fig. 2 can be removed, the recess 5 in the hinge part 4 on the opposite side of the receptacle 16 on a surface 21 with a radius of curvature R, which corresponds approximately to the distance between the longitudinal center axis S of the adjusting screw 8 and the surface 21. The distance of the flattened portion 14 of the hinge pin bushing 12 and the internal thread 13 is dimensioned so that the hinge pin bushing 12 is held substantially free of play between the surface 21 and the adjusting screw 8.

Now, if the adjusting screw 8 rotatably actuated, so shifts due to the fact that the adjusting screw 8 is fixed in the longitudinal direction by means of the component 17, by the threaded engagement, the hinge pin bushing 12 in the recess 5 first up and down, ie according to Fig. 2 depending on the direction of rotation of the adjusting screw 8 to the viewer to or away from this. Due to the engagement of the projection 15 in the link 20, the hinge pin bushing 12 leads to a movement about the longitudinal central axis S of the adjusting device 6 or approximately along the surface 21, as indicated by the double arrow P in Fig. 2 is symbolized. The determination of the hinge pin in the desired adjustment position are two grub screws 22, which are screwed into threaded holes 23 which open into the recess 5 of the hinge part 4. They each include a conical end portion 24, whose Cone angle is adapted to two provided in the hinge pin Rundumnuten 25, which are provided in a corresponding to that of the two setscrews 22 distance in the sand bolt 7.

In the areas in which the grub screws 22 act on the hinge pin 7, the hinge pin bushing 12 recesses 26 which are dimensioned such that the hinge pin bushing can be displaced by the grub screws 22 unhindered over the entire adjustment.

As in particular from Fig. 2 is apparent, the grub screws 22 act on the hinge pin 7 in one direction Fig. 2 upward, so that the hinge pin 7 is pressed when tightening the grub screws on the adjusting screw 8 and this in the receptacle 16, which ensures that the hinge pin bushing 12 at least guided virtually no play and the external thread of the adjusting screw 8 in secure engagement with the internal thread 13 is located.

Based on 4 to 6 that in their views Fig. 1 to 3 Now, another embodiment of the invention will be explained. Corresponding components or features are in the 4 to 6 with the same reference numerals as in the Fig. 1 to 3 , but increased by the value 100, denoted. To avoid repetition, only the differences are discussed.

The function of this band corresponds substantially to that of the above breischriebenen. However, first, the hinge pin 107 is formed longer, so that it is suitable for a three-piece band, in which the wing hinge part 200 is received between two frame hinge parts, not shown in the drawing.

Another difference between the wing hinge part 200, which however can also be used when the wing hinge part 200 is to be used as described above in a two-part band, is that the link 120 is not by means of a breakthrough directly into the material of the hinge part 4 is incorporated, but in an additional insert 127 which is arranged in a recess 128 adapted to its outer contour in the recess 105.

Although increased by the insert 127, the number of required for the wing hinge part 200 components, it is advantageous that is unnecessary by the use of the opening 19, so that in particular the penetration of contaminants into the interior of the hinge part is much more difficult.

To fix the insert 127, the grub screws 122 are used, which enforce this provided in the insert 127 holes 129. Otherwise, the leaf hinge part 200 corresponds to the leaf hinge part 100, but the projection 115 provided on the hinge pin bush 112 and the flattened region 114 are adapted to the position of the link 120 and the surface 121.

At the in Fig. 7 to 10 illustrated third embodiment of the invention, the leaf hinge part with 300 and accordingly corresponding components or features with the same reference numerals as in Fig. 1 to 3 , however, increased by 200, again denotes only the differences from this embodiment.

The wing hinge part 300 now additionally comprises a cover cap 230 which, at the attachment part-side end 231, comprises a projection 232 which engages in an undercut surface 233 provided on the attachment part 202.

The covering cap 230 comprises a region 234 which is approximately part-annular in cross-section and which surrounds the hinge part 204 on the outside over an angular range of approximately 200 °.

In particular FIGS. 9 and 10 can be removed, the component 217 is integrally formed on the inside of the region 243, so that a fixing of the adjusting screw 208 in the longitudinal direction by placing the cap 230 is effected.

To the cap 230 in patch, in Fig. 8 To fix the illustrated state, a fastening screw 235 is provided, which in the transition region between the fastening part 202 and the hinge part 204 from the back of the hinge strap 201 in a provided in the cap 230 threaded blind hole 236 can be screwed.

In the in the Fig. 11 to 15 illustrated fourth embodiment, the components or features of the leaf hinge part 400 again with the same reference numerals as in Fig. 1 to 3 , however, designated enlarged by 300. In contrast to the wing hinge part 100, the adjusting screw 308 is now located on the rear side of the hinge part 304 facing the wing, for which purpose the receptacle 316 is provided on the opposite side of the recess 305 in comparison to the wing hinge part 100. Accordingly, the gate 320 is provided at the front of the hinge part 304.

The projecting into the backdrop 320 and now of the visible projection 315 includes on the front of a scale 337. Together with a provided on the front of the hinge part 304 Strichmarkienrng 338 can be the current adjustment position of the hinge pin bushing 312 and thus the hinge pin 307 and at a Readjust adjustment made adjustment.

The fixation of the hinge pin 307 in the direction of the hinge axis A is now by means of a screwed from the back through a hole 339 fixing screw 340 which engages in a Rundumnut 325 in the hinge pin 307. For this purpose, the internal thread 313 of the hinge pin bushing 312 is broken into a slot-shaped recess 341.
