Description

The invention relates to a band of the preamble of claim 1 corresponding part.

Such a band is for example from the EP 0 467 075 B1 known. In the various embodiments of this known band either the actuation of the displacement means, by means of which the hinge pin along the slot-shaped cross-section opening for the purpose of adjusting the wing is displaceable in the frame, and / or the actuation of the fixing means, by means of which the hinge pin after reaching the adjustment position is set in the corresponding position, by a lateral access, in other words by access in a direction perpendicular to the longitudinal direction of the hinge pin plane.

With the generic band an adjustment of the wing in a direction perpendicular to the longitudinal axis of the hinge pin or the hinge axis direction is possible. Depending on the orientation of the hinge pin receiving, in cross-section slot-shaped opening in this case the adjustment can be made in the wing plane, so as to adjust the gap between the wing edges and the surrounding frame. Or it can be made an adjustment perpendicular to the wing plane, so as in wings with cover, ie in those that partially cover the front surface of the frame with a protruding edge, the distance of the Setting edge to the front surface of the frame. This is particularly important in those wings in which the protruding edge is part of a seal assembly to ensure the required for the desired sealing effect pressure of the seal on the front surface of the frame.

A disadvantage of the known band that it is always necessary to move the hinge pin along the slot-shaped opening in cross-section, ie perpendicular to the longitudinal direction of the hinge pin and / or fixing the hinge pin in the desired position to open the wing. In the event that the operation of the displacement means is only possible with the sash open, the adjustment can only be made in an iterative process. It must therefore be adjusted with the sash open and then checked with the sash closed, whether the desired adjustment has been made. In the event that the determination of the hinge pin in the slot-shaped cross-section opening can only be done with the wing open, there is a risk that when opening the wing for the purpose of fixing the hinge pin herausverlagert from its adjustment and the adjustment process must be repeated. The EP 0 837 206 A1 discloses a belt with a belt bolt having an eccentric portion. The eccentric portion has radial projections. These can be brought into contact with radial recesses of a receiving opening. The hinge pin has a hexagon on an end face, by means of which it can be rotated. On the same front side, a spring with an external toothing is provided as a fixing means.

The invention is therefore an object of the invention to provide a tape by means of which the adjustment process is simplified.

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

Characterized in that the displacement means and the fixing means are accessible from one or both front ends of the hinge pin, an actuation of both the displacement means, as well as the fixing means in any position of the wing, ie even with the wing closed, take place. By this measure, the exact position of the wing in the frame under observation of Gaps set and after reaching the desired position they are "frozen" by pressing the fixing without the wing must be relocated.
The engagement means comprise at least one tooth projecting radially from the hinge pin and engaging a recess formed in one of the longitudinal walls. By this formation of the engagement is granted in a simple manner on the one hand, that the hinge pin can not tilt in the slot-shaped cross-section recess, which would lead to tilting of the hinge axis and excessive mechanical stresses during the operation of the wing, but at the same time a displaceability of the hinge pin in the adjustment direction along the longitudinal side of the slot-shaped opening in cross section is possible.
Depending on the length of the maximum achievable adjustment path and the size and shape of the tooth already a tooth and a tooth cavity may be sufficient. However, it is also possible to carry out over a part of the circumference of the hinge pin extending toothing, which engages in a machined into the longitudinal wall, complementary teeth.

Includes - as preferred the teeth of the hinge pin an odd number of teeth, so an embodiment is particularly preferred in which the central tooth and the associated tooth cavity of the remaining teeth and tooth recesses have different dimensions. By this measure, the insertion of the hinge pin is facilitated in the correct position, which ensures maximum displacement in both directions. It is thus not possible to use the hinge pin in a "twisted" position, in spite of the center position, the teeth are already "at the stop" and thus a shift is only possible in one direction.

The displacement means comprise a device provided at the one end face of the hinge pin for the attachment of a turning tool. This device may have a hexagon socket.

The fixing means comprise a clamping screw which can be screwed into the other end-side end of the hinge pin. The clamping screw is designed such that it acts directly or indirectly via a contact surface against a clamping surface. The contact surface can be formed, for example, by a circumferential collar provided between the head and the thread of the clamping screw, or by a preferably captively mounted washer.
By means of the clamping screw, the determination of the hinge pin in the desired position preferably takes place in that the band part, the clamping screw comprehensive end of the hinge pin receiving member has a clamping surface against which the clamping screw with the contact surface for the purpose of fixing the hinge pin in the opening clamped is.
For receiving clamping forces permitting reaction forces, the hinge pin preferably comprises a circumferential collar, by means of which it is supported on the base surface of a lateral recess of the opening.
Particularly cost-effective to produce the hinge pin, if it comprises a core of metallic material having a sheath made of plastic. As a result of this measure, in particular when the casing is produced by the injection molding process, no elaborate mechanical processing of the hinge pin is required in order, for example, to produce the toothing.
The insertion of the hinge pin in the middle position during assembly of the band is again facilitated when the hinge pin on the opposite side of the engagement means comprises at least one locking projection which engages in the central position of the hinge pin in the slot-shaped cross-section opening in a latching groove. In this case, latching projection and latching groove are formed so that a displacement of the hinge pin in the longitudinal direction of the slot-shaped opening in cross section overcoming the elastic latching force is possible, however, insertion of the hinge pin in the slot-shaped recess outside the center position is possible only under an increased force. By this measure Therefore, a fitter already "feels" if he is about to insert the hinge pin in the correct position.

The process of joining is again facilitated if, in addition to or alternatively to the latching projection and the latching groove, optically detectable markings are provided which mark the center position of the hinge pin in the slot-shaped recess in cross-section.

The band designated as a whole by 100 comprises a frame band part 1 which can be fastened to a frame, not shown in the drawing, by means of fastening screws 2 and dowel pins 3, and a wing band part 6 which can be fastened to a wing likewise not shown in the drawing by means of fastening screws 4 and dowel pins 5.

The frame hinge part 1 and the wing hinge part 6 are hingedly connected to each other by means of a hinge pin 7, wherein the central longitudinal axis of the hinge pin 7 defines the hinge axis S.

As in particular from Fig. 2 can be seen, showing the hinge part 8 of the wing hinge part 6 in a single representation, the hinge part 8 has a slot-shaped opening 9 in cross-section. It is limited by the part-circular curved narrow walls 10, 11 and the flat longitudinal walls 12, 13th

In the longitudinal wall 12, a toothing 14 is incorporated, which is in engagement with a provided on the outer circumference of the hinge pin 7 teeth 15 with inserted hinge pin. The teeth 14 and 15 form engagement means 16 over which the hinge pin 7 is in positive engagement with the longitudinal wall 12.

As in particular from Fig. 1 is apparent, a displacement of the hinge pin 7 along the slot-shaped cross-section opening 9, ie in the direction of the double arrow P in Fig.1 be shifted in which the in a rotary motion is offset. To initiate this, the hinge pin, as in Fig. 3, 4 . 10 and 11 can be seen, at the front end of its resting in the frame hinge part 1 section 17 a hexagon socket 18, in which a suitable tool can be used for the purpose of adjustment.

In order to prevent that the hinge pin 7 in a twisted position, which is the exhaustion of the length L of the slot-shaped cross-sectional opening 9 is not fully utilized, is used, is the central tooth 19 of the teeth 15 and the associated Tooth well 20 of the toothing 14 formed larger than the remaining teeth. In order to facilitate the finding of the center position, on the opposite side of the toothed pin 15 of the hinge pin 7 locking lugs 21, 21 '(see. Fig. 9 ) are provided, which engage in the inserted state of the hinge pin in an incorporated in the longitudinal wall 13 of the opening 9 locking groove 22. A displacement of the hinge pin 7 in the direction of the double arrow P is possible by overcoming the effect of the engagement of the locking lugs 21, 21 'in the detent groove 22 elastic force.

In particular 10 and 11 can be removed, an internal thread 24 is incorporated into the front end of the portion 23 of the hinge pin 7, which engages in the opening 9. It is used to screw a clamping screw 25, which in detail in FIGS. 7 and 8 is shown. It has a between its thread 26 and its head 27 arranged circumferential collar 28, the underside forms a contact surface 29. Between the sections 17 and 23, the hinge pin 7 also has a peripheral collar 30. Furthermore, lateral recesses 31 are provided in the leaf hinge part at both ends of the opening, of which in the drawing only the in Fig. 1 facing the viewer is recognizable. The peripheral collar 30 of the hinge pin 7 is positioned such that by tightening the clamping screw 25 a clamping fit between the contact surface 29 and a bearing surface 32 formed by the circumferential collar by supporting the contact surfaces 29 and 32 in the base surfaces 33 of the respective recess is effected.

The hinge pin 7 comprises a core 34 made of a metallic material, which is surrounded by a sheath 35 made of plastic. Furthermore, the hinge pin on the front side of the section 23 optical marks 36 which extend in its central position perpendicular to the longitudinal walls 12, 13.

With the tape according to the invention an adjustment and fixing the wing in the frame in a particularly simple manner possible that after loosening the clamping screw 25 required for the adjustment rotational actuation of the hinge pin 7 by engagement of a tool in the hexagon socket 18, wherein the fixation in the adjustment position is carried out by subsequent re-tightening the clamping screw 25 while holding the hinge pin in its required position for the adjustment.

Furthermore, the above description shows that the band according to the invention is characterized by a particularly small number of components.
