Description

The invention relates to a fitting for an aluminum shutter with a fixable on the shutter mounting plate, on which first and second support arms are arranged with these laterally projecting retaining lugs, the one Rear section of the aluminum shutter, and which two-part is formed with two form-fitting interlocking parts, wherein at least a first holding arm on the first part and at least one second holding arm is arranged on the second part of the mounting plate and wherein for clamping the retaining arms against the undercut portion of the aluminum shutter a clamping screw passes through the mounting plate.

A fitting for a shutter in the form of a hinge fitting was e.g. known from EP 1001 124 A1. In this known hinge fitting has a fitting part, usually this is the part that a socket for receiving a pin-shaped counter fitting, a rectangular Slit on, which is substantially perpendicular to the axis of the socket of this Fittings extends. In this slot grab two spaced apart Guide pin a second fitting part and are in this slot adjustable. This second fitting part passes through a parallel to the axis of the Bush extending slot in the shutter, said second fitting part the edges of the slot of the shutter with a flange-shaped neck overlaps.

To fix the fitting is a screw with nut and a pressure plate provided, which covers the slot of the first fitting part and of the Screw is interspersed. By tightening the screw, which is also the second Passed fitting part and engages the nut, the flange-like approach of the second fitting part and the pressure plate against the shutter pressed and thus ensures a corresponding frictional engagement between these parts become.

In this known solution, there is the disadvantage that the shutter must be broken. The production of the slot in the shutter requires a considerable effort, especially if made on site must become. Moreover, only a relatively small adjustment of the fitting opposite the shutter in the size of usually less than 15mm be realized when the fitting, in particular the flange-like approach of second fitting parts, not undesirably large dimensions. But also the adjustment of the two fitting parts against each other can only be relative kept small.

Furthermore, a fitting was known from DE 44 31 278 A1, the one in a Has fitting groove to be used clamping piece, which corresponds to a sliding block. This clamping piece is integral with a via a coupling web Attachment plate connected. At the transition of the coupling web to the clamping piece and to the contact plate of the coupling web is formed in each case with an articulated Connecting webs connected. In this case, the bearing plate with a countersink Provided through hole, to which a cross the coupling web Breakthrough connects, with a threaded hole in the clamping piece for Recording a clamping screw is provided. By means of the clamping screw can pulled the clamping piece against the contact plate of the base and the transverse webs the fitting groove between the terminal strips of the clamping piece and the Contact surfaces of the contact plate are clamped.

In this solution, the disadvantage of a relatively high production costs, in particular, the joint joints, which are practically used as film hinges are formed, bring significant problems in mass production. In addition, the Klemmstuck and the contact plate with the coupling web be made of plastic.

By previous use is also a fitting for an aluminum shutter became known, which comprises a fixable on the shutter Befesitungsplatte, at the first and second support arms with laterally projecting from this Holding lugs are arranged. At the shutter are parallel to each other Grooves provided, which have broadening in a suitable place to to allow insertion of the retaining arms with the retaining lugs. Subsequently the mounting plate can be moved in the grooves and at the appropriate Place by means of a clamping plate passing through the mounting plate by tensioning the retaining lugs against the undercuts of the grooves be fixed at the shutter. The disadvantage here is that the broadening the grooves in the manufacture of shuttering an additional manufacturing step in which appropriate cutouts are performed and this makes the manufacture of the shutter more expensive. Also disturb these Broadening the overall visual impression of the shutter. Further results by the requirement of threading into the enlargements and subsequent ones Moving the mounting plate an additional installation effort.

A fitting of the aforementioned type is known from EP 0 528 213 A1. In this two-piece fitting, the first part has a holding arm with a retaining lug on and the second part is pivotable in the first part mounted terminal block formed with a further retaining lug. A clamping screw passes through the first part and presses the retaining lug when screwing in the terminal block in the undercut area of a groove, in which the two Holding lugs are introduced.

A disadvantage of this known fitting, inter alia, that the distance the holding arms correspond approximately to the diameter of the clamping screw must and therefore is relatively low. The design of the groove must be there be adapted, this has a relatively large width. In addition, the Stability in the assembled state is not particularly high or the overall training relatively expensive.

The aim of the invention is to avoid these disadvantages and a fitting of the provide at the beginning of the type mentioned at different points of the Shutter is easy to install, with an advantageous embodiment of the shutter is possible.

This is according to the invention in a fitting of the type mentioned achieved by the characterizing features of claim 1.

By the proposed measures, the two parts of the mounting plate be used separately in the profile. It is also possible these parts e.g. insert in grooves whose width is at least the width of the support arms along with those protruding from them. This allows a Inserting each part of the mounting plate at any point of the groove of the shutter. After inserting both parts of the mounting plate can these are shifted against each other to form a positive connection to reach these parts. The grooves of the shutter need not Have widenings by milling to the insertion of the support arms to allow the mounting plate. Instead of grooves can to Allow the attachment of the fitting, for example, also projections the side edges of the shutter to be provided by the retaining lugs can be underrun. The front surface of the shutter can thereby be formed free of grooves. Such grooves not only present a visual impairment of the shutter, but also pollute in the course of Time.

In this context, it is advantageous to provide the features of claim 2. By these measures can easily a form-fitting Connection of the two parts of the mounting plate are made. To it suffices these parts after their insertion in the frame against each other move and thereby the approach of one part in the corresponding recess of the other part.

In the case of the formation of the fitting as a hinge fitting, it is advantageous when the mounting plate on its side facing the shutter a Has recess for receiving a hinge part, wherein the clamping screw on the inserted hinge part rests on the shutter. This allows the clamping screw to fix the mounting plate serves, at the same time used for fixing a fitting part of a hinge become.

In this case, in a direction parallel to the main plane of the frame 20 Surface of the frame 20 incorporated parallel grooves 22 which, as can be seen from Figs. 3 and 4, are undercut. Here are the undercut Regions 24 of the grooves 22 facing each other.

In these grooves 22 of the frame 20 engage mounting plates 25 which are formed in two parts, as shown in the left shutter in FIG is. In this case, each of the two parts 3 and 4 engages with a holding arm 1, to whose free end a retaining lug 2 projects substantially perpendicularly, in each case a groove 22 a. The width b of the holding arms along with those of them projecting retaining lugs 2 corresponds to the smallest width B of the grooves 22, or falls slightly below this. This allows the parts 3 and 4 of the mounting plates 25 used at any point of the frame in the grooves 22 become.

To the two parts inserted into the grooves 3 and 4 of the mounting plates 25 positively connect with each other, the part 4 has an undercut Recess 6, in the assembled state, a substantially gegengleicher Approach 5 of the second part 3 engages. This is an insertion of the approach 5, in the illustrated embodiment at its free end a has thickened head 7, in the recess 6 of the part 4 in the direction parallel to the groove 22 only possible if the two parts 3 and 4 of the mounting plate 25 are pushed toward each other and the retaining lugs 2 of the support arms 1 in the undercut portions 24 of the grooves 22 of the frame 20 engage.

In the illustrated embodiment, the approach 5 extends when mounted Mounting plate substantially parallel to the main plane of the frame 20th However, this is not essential. The approach 5 could e.g. also through one of the part 3 obliquely projecting bar to be formed in a corresponding opposite recess of the part 4 engages. It is essential that one positive connection of the two parts 3, 4 on the one hand to a Pulling the parts 3, 4 in the direction parallel to the main plane of the holding plate (parallel to the surface of the shutter), on the other hand opposite a mutual pivoting about a parallel to the main plane of the retaining plate lying axis is given.

In the fittings according to FIGS. 1 to 4, the parts 3 and 4 of the mounting plates 25 recesses on its underside facing the shutter 8, 9, which are parallel to the retaining lugs 2, or in the mounted state the mounting plates 25 perpendicular to the longitudinal extent of this holding Grooves 22 extend. In these recesses 8, 9, in the assembled state the mounting plate extending over the two parts 3, 4 extending Resulting recess, hinge parts 12 can be inserted and with a clamping screw 10 are fixed in corresponding threaded holes 11 of the parts 3 of the mounting plates 25 are used.
