Different embodiments of a feedback device 10 for feedback of a frame 12 are shown in Figures 1, 2, 4 to 9, as well as 11 and 12, of which a frame bar 14 is shown together with the feedback device 10. feedback and a fastener 16 in Figure 4 and Figure 10.

The frame 12 has, for example, two frame bars 14 (only one shown) to be arranged vertically, which are to be connected by means of several fasteners 16 at fixing points 18 with a wall area, which borders a structural opening. The structural opening and the wall area have not been represented in the figures; examples of realization of them can be seen in the current state of the art mentioned at the beginning. The fixing of the respective frame bar 14 takes place by means of the fastener 16, where the frame bar 14, to be fixed directly with the fastener 16 so that a head 16 of the fastener fits directly into a profile 20 of the bar 14 of frame, to be fed back through the feedback device 10. The frame bar 14 allows an oblique mounting of the fastener 16; This is also known basically from the current state of the art mentioned at the beginning.

All embodiments of the feedback device 10 have a first spacer element 22, in which a first support surface 24 is configured, and a second spacer element 26, in which a second support surface 28 is configured. In the case of use of the feedback device 10 according to the standards, the first support surface 24 supports the frame bar 14, and the second support surface 28 rests on the wall area, which is not shown here in more detail. .

The different embodiments of the feedback device 10 also have an adjustment and tightening device 30 by which the spacing between the support surfaces 24, 28 can be adjusted. By increasing the spacing between the support surfaces 24, 28, the frame 12 can be tensioned within the structural opening.

For example, both frame bars 14 of the frame 12 to be arranged vertically are respectively fixed in the wall area at several fixing points 18 spaced apart in the longitudinal direction of the frame bar 14 by means of a fastener 16 guided through an opening in the frame bar 14, where in each of these fixing points 18, a feedback device 10 is inserted between the frame bar 14 and the wall area. The fastener 16 is configured, for example, as a pin and screw fastener, with only the screw 32 being shown in the figures.

The feedback device 10 has a through opening 34 for the fastener 16 to penetrate. The through opening 34 is formed respectively by an opening 36 in the first support surface 24 and in the second support surface 28. The openings 36 in the support surfaces 24, 28 are preferably provided so that they at least partially overlap each other.

The adjustment and tightening device 30 can be formed in different ways; Different embodiments are clarified in more detail below.

The first spacer element 22 preferably has a base plate 38, which can be inserted, for example, with clamping flanges 40 into corresponding sets of claws of the frame bar 14, not shown here.

The second spacer element 26 has, for example, a holding plate or cover plate 42.

A guide 44 is further provided to guide a relative movement of the spacer elements 22, 26 in a direction transverse to the support surfaces 24, 28.

The guide 44 has, for example, a guide groove 46 in one or both elements 22, 26 spacers and a hook element 48, which engages in the guide groove 46. In some embodiments, the latching element 48 is formed integrally in one piece on the other of the spacer elements 22, 26 and is configured, for example, as a shoulder 50, which fits into the guide groove 46. In other embodiments, the latch member 48 is a separate member, for example, a sliding nut 52.

Preferably, two guides 44 are provided on opposite sides of the feedback device 10.

The adjustment and tightening device 30 preferably has at least one cuneiform surface 54 on at least one of the spacer elements 22, 26 and a cuneiform element 58 operable by means of a propelling element 56. In another embodiment, a thread 60 or a toothing is configured in at least one of the spacer elements 22, 26, with a rotating element 62 being configured in the other of the spacer elements 22, 26, which engages in the thread 60 and which can be driven by drive element 56.

Below, the first embodiment of the feedback device 10, as shown in Figures 1 to 3, is first explained in greater detail. The other embodiments can be configured analogously except for the differences explicitly clarified.

The first spacer element 22 has the base plate 48 as well as side plates 64, in which the guide groove 46 is configured facing inwards. In the terminal areas, which run transversely to the side plates 64, the first spacer element 22 has the first wedge-shaped surfaces 54a.

The second spacer element 26 has the clamping plate or cover plate 42. On the opposite side to the second support surface 28, the base plate 38 has been provided with bevels that form second cuneiform surfaces 54b, which have been configured at corresponding points as in the first cuneiform surfaces 54a, but evidently with opposite slope.

The adjustment and tightening device 30 has a first wedge-shaped element 58a and a second wedge-shaped element 58b as well as an adjusting screw as a drive element 56.

The wedge-shaped elements 58a, 58b have threaded openings, through which the adjusting screw 66 is guided. By turning the adjusting screw 66, the mutual position of the wedge-shaped elements 58a, 58b is modified. Each of the cuneiform elements 58a, 58b engages on one side with the first cuneiform surface 54a and on the second side with the second cuneiform surface 54b. Thus, by bringing the cuneiform elements 58a, 58b closer to each other and moving the cuneiform elements 58a, 58b away from each other on the cuneiform surfaces 54, 54a, 54b, the distance between the support surfaces 24, 28 is adjusted.

The spacer elements 22, 26 may be made of fiber reinforced plastic, for example, glass fiber reinforced polyamide. Particularly preferred is plastic provided with flame retardants. In other configurations, the spacer elements 22, 26 have been made of metal. The wedge-shaped elements 58 are preferably configured from the same material as the spacer elements 22, 26.

Thus, the feedback device 10 has been configured, for example, with four plastic parts, which are joined by means of a screw 66. The thread of the openings of the wedge-shaped elements 58a, 58b can be made, for example , by a rivet nut. By turning the adjusting screw 66, the wedge-shaped elements 58a, 58b, which act as clamping wedges, are brought closer to each other and form an inclined plane with the base plate 38 and the clamping plate or cover plate 42 and thus raise the clamping plate. or cover plate 42.

The spacer elements 26, 22 have several guides and thus enable controlled tensioning in the Z direction.

Therefore, the feedback device 10 has been configured as a tensioner. The tensioner can preferably generate only pressure. The second spacer element 26 has preferably not been secured with an end stop and can therefore be removed upwards. Once the second spacer element 26 has been removed, the cuneiform elements 58 can be removed. A relatively large height adjustment is possible, in particular from 10 mm to 30 mm. In the setting with the smallest separation between the support surfaces 24, 28, an extension of the entire feedback device of a maximum of 13 mm in the Z direction is preferably provided.

A fastening system (for example, a hook element) for the feedback device 10 has been installed on the frame 12, which is not shown in detail here. Such a system may consist of a simple bent sheet, which may be welded, for example, to the frame bar 14 at each fixing point 18 as a pair of mutually opposite points, so that the feedback device 10 can be pushed inward. with its fixing flanges 40. Alternatively, fixation can be carried out using an adhesive. In particular, when the first spacer element 22 has been made of metal, welding can also be performed, as indicated in Figure 9 by means of welding tabs 84.

In the case of a wall surround frame, the frame bar has an opening at each of the fixing points for access of the fixing screw 66 (not shown).

The feedback device 10 is preferably configured from fireproof materials so that it can be used in fire protection door frames.

In the case of a modification, instead of the rigid guide 44 an articulated guide is provided so that an angle between the support surfaces 24, 28 can also be adjusted to create compensation on an uneven wall. The feedback device 10, which has been designed as a tensioner, offers a very convenient alternative to the feedback devices, explained in the state of the art mentioned at the beginning with covering plates. The feedback device 10 enables very precise alignment of the frame. The corresponding installer does not have to worry on site about missing cladding pieces.

The fastener 16 can be guided through the opening 36. A fixing screw of the frame can thus be guided through the feedback device 10. The support surfaces 24, 28 thus support the respective frame bar 14 at the fixing point 18 so that deformations even of the frame bar are kept very low.

The second embodiment of the feedback device shown in Figures 4 to 6 is very similar to the first embodiment, so reference can be made to its description. In addition to the adjusting screw 66, the adjusting and tightening device 30 also has a second drive element 56, for example a grub screw 68. The multiple drive elements 56 have been coupled in a mutually synchronized manner by means of a corresponding transmission mechanism 70, which may have, for example, a toothed wheel, a belt or the like.

This creates a parallel drive 72.

In the third embodiment of the feedback device 10 shown in Figures 7 to 9, the spacer elements 22, 26 have been configured in an annular shape and, in particular, in a round annular shape. The wedge-shaped surfaces 54a, 54b have accordingly been configured as conical surfaces. The elements 58 cuneiforms have been configured as annular segments 64. Its movement is carried out radially. As a drive element 56, for example, a hose clamp 76 can serve.

In this embodiment, an inclination of the spacer elements 22, 26 is also possible due to the conical surfaces.

The openings 36 of the support surfaces 24, 28 may be bevelled to enable diagonal fixing of the fastener 26, see Figure 9.

In the fourth embodiment shown in Figures 11 and 12, the second spacer element 26 is provided with an external thread on its outer face. Also in this case the spacer elements 22, 26 have been configured with an annular shape and mutually inserted. The first spacer element 22 can be configured as a housing 78, inside which a rotating ring 80 is rotatably housed, which can be driven as a drive element 56 by a worm wheel or similar or by a threaded movement spindle. By rotation of the rotary ring 80 in the housing 78 with respect to the external thread 82, the relative movement of the spacer elements 22, 26 and, therefore, the adjustment of the separation between the support surfaces 24, 28 occurs. A slotted nut 52 can also be applied to the housing 78, which engages in the guide slot 46 of the second spacer element 26 to prevent its rotation.
