Description

The invention relates to a system for fastening a fitting part, having a profile which comprises an undercut longitudinal groove whose opening is formed by two longitudinal ribs which are arranged on opposite sides of the longitudinal groove, wherein the longitudinal ribs a pair of outer longitudinal surfaces and a pair of inner longitudinal surfaces, and with a mounting assembly, the at least one outer contact surface, which is intended to abut on an outer longitudinal surface and at least one inner contact surface, which is intended to abut against an inner longitudinal surface comprises.

Such a system is from the DE 602 08 486 T2 known. It comprises a projecting anchoring area with an anchoring surface intended to be pressed against a region of a first of the inner longitudinal surfaces of the groove. Also provided is an anchoring plate which is inserted into the groove from an open longitudinal end and is intended to press against the projecting anchoring area and which has an inner contact surface for abutment with a second of the inner longitudinal faces. The mounting plate has two threaded holes in which mounting screws that enforce the fitting, are screwed. The projecting anchoring area is connected to the fitting via a deformable zone. The anchoring plate lies on the projecting anchoring area in such a way that upon tightening the fastening screws, the inner contact surface of the projecting anchoring portion is brought into contact with the inner longitudinal surface.

A disadvantage of this device is that it requires threading the anchoring plate into the groove and then positioning it relative to the fitting part in a position in which the fastening screws can be screwed. The assembly of the fitting with this system is therefore difficult.

From the EP 1 972 743 A2 is a closing member for mounting in an elongated receptacle of a blind or sash of a window, a door or the like with a Schließteilgrundkörper, on the upper side at least one holding portion for a locking element of the window, the door or the like is provided known. At the bottom of Schließteilgrundkörpers a flat clamping element is arranged, which is connected to the closing part base body via an adjustable fastening element. The clamping element and the fastening element can be tilted together relative to the closing part base body, so that it is possible to introduce the clamping element initially with a clamping edge obliquely from above into the receiving groove, that this clamping edge comes to rest under one of the marginal edges of the receiving groove. Upon complete insertion of the clamping element into the receiving groove, the clamping element tilts together with the fastening element until the clamping element and closing body part are aligned parallel to each other. In this state, the closing part is fixed by clamping in the receiving groove.

The DE 20 2004 011 538 U1 discloses a clampable adjustment and / or assembly aid in the attachment of a band to a profile having two profile extensions and a profile groove. This adjustment and / or assembly aid comprises two clamping parts, which are pivotable relative to each other about a pivot axis. Each of the clamping parts comprises a groove for receiving one of the two profile extensions.

A fitting for attachment in a profile groove undercut on both sides is from the EP 539 672 A1 known. It consists of a fastening part and a Clamping part, which are connected by means of screws spacing variable and are guided by inclined guide surfaces to each other.

The invention is therefore based on the object to provide a system which is improved in terms of these disadvantages and allows a particularly simple, reliable and adjustable attachment of a fitting part.

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

In the system according to the invention, the mounting assembly comprises two clamping elements each having a clamping groove, of which at least one has two facing surfaces, one of which forms an outer, the other an inner contact surface. The clamping elements are arranged so that they can be displaced between a first position in which they are insertable into the opening of the longitudinal groove, and a second position in which the contact surfaces bear against the longitudinal surfaces. An assembly of the fitting takes place in the system according to the invention by the clamping elements initially placed in the first position and the fitting is positioned at the desired location of the longitudinal groove. Subsequently, the clamping elements are moved to the second position, in which the fitting part is positioned in the longitudinal groove.

The mounting assembly is designed such that the two clamping elements in a direction parallel to the longitudinal direction of the longitudinal groove pivot axis are mutually pivotable. In the first position, the two clamping elements are then in an angular position to each other, which is smaller angle than the second position, in which the two clamping elements are preferably at an angle of slightly greater than 180 ° to each other. The second-mentioned angular position leads to a "self-locking" of the two clamping elements against automatic release. The leading to the attachment of the fitting part clamping seat of the clamping elements in the longitudinal groove is accordingly effected by an extension of the two clamping elements and the consequent engagement of the longitudinal ribs in the clamping grooves. In this case, the stretching operation, for example, by a compressive load of the clamping elements approximately in the region of the pivot axis perpendicular to this, for example by a targeted blow with a hammer, be effected. The assembly of the fitting is therefore characterized by a particular simplicity.

In the system according to the invention, a first of the clamping elements in the longitudinal direction of the longitudinal groove is displaceably connected to the fastening part, whereby an adjustment of the fastening part and thus of the fitting part in the longitudinal direction of the longitudinal groove is made possible, without requiring a release of the clamping elements in the longitudinal groove is required.

The constructive implementation of this adjustability can be two spaced apart in the longitudinal direction of the longitudinal groove spindle receptacles, each having a threaded bore serve. The threaded bores are arranged on a common axis parallel to the longitudinal direction of the longitudinal groove. The first clamping element is inserted with Justierspiel in the direction of the axis in the distance space between the spindle receptacles. In the threaded holes threaded screws are screwed to these complementary external thread, each comprising a threadless extension at their ends facing each other. Each extension engages in a recess of the first clamping element. An adjustment in the direction of the longitudinal axis of the longitudinal groove can then take place in which either the two threaded spindles are rotationally actuated simultaneously in a rotational sense, that the distance between their non-threaded extensions does not change, however, the extensions displace in the distance space. Or it is first that threaded spindle, in the direction of the adjustment should be made, solved and adjusted the other threaded spindle accordingly until the desired adjustment position has been reached.

For the purpose of locking the fastening part in the second position, a fixing screw extending through the fastening screw can be provided, which can be screwed into a thread adapted to the locking screw in the second clamping element and lock in the tightened state, the clamping elements in the second position. In this case, the locking screw and adapted to it thread can be designed such that a screwing is only possible when the two clamping elements are in the second position. Or the locking screw and the thread are formed such that the locking screw can already be screwed into the thread in the first position located in the clamping elements and the further tightening the clamping elements are moved to the second position and locked in this.

Very particularly preferred is a development of the system according to the invention, in which in the fastening part a threaded bore is provided, in which a release screw can be screwed, which displace the clamping elements in their first position when tightening. This measure makes it possible to move the assembly assembly from its second to its first position without damaging components of this assembly or the profile groove in the release process.

Additionally or alternatively, a measure for attaching a lifting tool, for example a recess into which the blade of a slotted screwdriver can be inserted, may be provided for releasing, in order to displace the clamping elements into their first position.

The system according to the invention is particularly suitable for fastening a fitting part, which forms part of a hinge band.

The invention also extends to a mounting assembly as such of a system as described above and to a door comprising a door leaf, a door frame and a system as described above.

The profile 1 comprises an undercut longitudinal groove 4, the opening 5 of two longitudinal ribs 6, 7 is formed, which are arranged on opposite sides of the longitudinal groove 4. The longitudinal ribs 6, 7 form a pair of outer longitudinal surfaces 8, 9 and a pair of inner longitudinal surfaces 10, 11.

Furthermore, the system 100 includes a mounting assembly 12, the structure and operation of the basis of the Fig. 2 to 12 will be explained in more detail below.

The mounting assembly 12 includes a mounting part 13 for the fitting part 2, which is formed as a solid aluminum part. It comprises projections 14, 15, 16, which serve to hold the fitting part and are adapted to the design of the respective fitting part. On the side facing the profile 1 17 of the fastening part 13 are a first clamping element 18 and a pivot axis about a parallel to the longitudinal direction of the longitudinal groove extending pivot axis T at the first clamping element 18 attached second clamping element 19 is provided. For pivotally mounting the two clamping elements, the first clamping element 18 comprises a connection region 20 whose extension in the direction of the pivot axis T with the exception of an assembly and operating clearance of the length of a distance space 21 between two connecting portions 22, 23 of the second clamping member 19 corresponds. In the direction of the pivot axis T are from the mutually facing end faces of the two connecting portions 22, 23 each have a bearing pin 24, of which only one in Fig. 2 , Detail B is recognizable. The bearing pins 24 have the cross-section of a symmetrical to the pivot axis T by mutually parallel side surfaces 25, 26 flattened cylinder. For receiving the bearing pin 24 are used bearing openings 27, which are provided at the facing away from each other end faces of the connecting portion 20. The bearing openings 27, which in detail in Fig. 2 , Detail A are recognizable, have a the outer circumferential surface of the connecting portion 20 passing through slot 28, which opens into a bore 29 whose central axis coincides with the pivot axis T opens. The width of the slot 28 is slightly larger than the distance of the side surfaces 25, 26 of the journal 24 formed. The diameter of the bore 29 corresponds to - except for a bearing clearance - the diameter of the cylindrical portion of the journal 24. Are the first and second clamping elements placed in an angular position in which the slot 28 and the side surfaces 25, 26 are aligned, which in the illustrated embodiment at an approximately 90 ° tilting of the two clamping elements is the case, the two clamping elements 18, 19 brought into engagement with each other and locked by tilting about the pivot axis T with each other.

For attachment of the unit thus obtained from the first and second clamping element 18, 19, the fastening part 13 comprises two spaced longitudinally of the longitudinal groove spindle receptacles 30, 31. Each spindle receptacle has a threaded bore 32, 33, wherein the threaded bores on a common, to the longitudinal direction of Longitudinal groove 4 parallel axis S are arranged. The first clamping element 18 has a length L that it can be inserted with a Justierspiel in the direction of the axis S in the distance space 34 between the two spindle receptacles 30, 31. In this case, the fastening part 13 is such is formed such that it forms an angle stop for the second clamping element 19, which prevents it from being brought into the previously described angular position in which the clamping elements 18, 19 can be joined together. The clamping elements 18, 19 are thereby captive when the assembly assembly 12 is assembled.

As in 6 and 7 The threaded spindles each comprise an external thread 37, 38 complementary to the respective threaded bore 32, 33, from each of which a threadless extension 39, 40 is provided on the mutually facing end faces extends. The projections cylindrical in the illustrated embodiment extend into complementary recesses 41, 42 of the first clamping member 18. At the facing away from each other end faces of the threaded spindle 35, 36 Innenvielkantausnehmungen 43, 44 are provided for applying rotary tools. A displacement of the fastening part 13 relative to the first and second clamping elements 18, 19 in the direction of the axis S can be carried out by appropriate rotational actuation of the threaded spindles 35, 36, wherein the rotary actuation regularly takes place simultaneously or alternately in such a way that both extensions during the displacement process 39, 40 are located at least over part of their length in the associated recesses 41, 42.

The attachment of the mounting assembly takes place, as from the Fig. 8 to 10 becomes clear by first the fastening part 13 and the unit consisting of first and second clamping element 18, 19 are assembled by assembling and screwing the threaded spindles 35, 36 to the mounting assembly 12. Subsequently, the fastening part 13 with the first clamping element 18 and the second clamping element 19 are bent so far that the two clamping elements 18, 19 can be placed with their provided on the parallel surfaces spaced clamping grooves 45, 46 on the longitudinal ribs 6, 7.
