Arrangement of fittings element

Technical field

The invention relates to an arrangement of a fitting element of the kind corresponding to the preamble of claim 1.

A preferred example for a "fitting element" is the hinge part of a door, window, etc. mounted on a fixed frame or a sash frame.

BACKGROUND OF THE INVENTION

An arrangement according to the preamble of claim 1 is known from DE 30 15 354 A1. The fixed frame and the sash frame are made of hollow profiles, with the sash closed, a C-shaped groove is formed on each of the opposite sides of the frames, which is open outwards, that is to the opposite frame. The fitting element in this case is a hinge-type hinge, the two flat parts of which extend from the hinge pin located in front of the frame and extend between the frame profiles. A bar clip is fitted inside the existing grooves. The screws extending in a direction perpendicular to the hinges and the clamps pull the hinges and the corresponding clamps against each other so that the opposite beaks of the groove C cross-section are firmly clamped between them and in this way the hinge can be anchored at any point along the entire length of the profile.

A similar arrangement is also based on FR 25 49 518, where, however, the mounting part of the hinge section of the angular profile extends over the front edge of the profile to the front side of the sash frame.

With such an arrangement, the clamps almost completely fill the groove of the cross-section C and cannot be inserted directly into the groove. It is therefore necessary to insert them longitudinally from the end of the profile. This condition requires inserting the clips into the profile before joining it in a square frame. In practice, when manufacturing this type of frames for windows, doors, etc., and when fitting hinges into them, this is a disadvantageous factor.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the invention to provide a type of arrangement in which the hinge can be fixed at any time, regardless of the mounting of the frame. This object has been achieved by the method set forth in claim 1 of the invention.

By attaching both the fastener and the clip to the groove beaks from different sides, it is possible for both the fastener and the fastener to be introduced into the profile groove from the outside at any point in the profile by the respective part of each of the two elements is introduced from the outside into the profile by sliding under the opposite beak of the groove. The gripping of the two beaks between the fastening part and the clamp is done in a manner identical to that of the current technical level, with the only difference that the mounting of the two parts is alternating, i.e. one outside and one inside. This does not reduce the strength of the attachment, but handling and fitting is facilitated, since it can be performed at any point in the profile from the groove opening and there is no need to pre-insert any elements from the end of the profile.

In order to be able to simply alternate insertion of the buckle one of the inner and the second from the outside, it is recommended to make it from a flat material at an angle of kink according to claim 2 of the invention.

- 1 CZ 297727-6

In principle, the fastening part and the clip can be arranged side by side in the longitudinal direction of the groove of cross-section C. However, this is not optimal due to the one-sided attachment.

In a preferred embodiment according to the invention according to claim 3, therefore, in one variant, a U-shaped buckle is provided so that the fastening part which has to cross the buckle penetrates the buckle due to this recess, thereby securing the fastening part from both sides seen in longitudinal direction. In the second variant, the U-shaped fastening part is made and the clip penetrates it.

In order that the force can be distributed over as large a surface as possible and that the torque arm is as advantageous as possible, it is recommended that the embodiment according to claim 4 be the most suitable.

The hinges are usually made of aluminum alloy. Although the transmission of forces at the hinge according to claim 5 may be more appropriate, cutting out (cutting) the extruded profile necessary to form mutually parallel planar delimiting surfaces that have a small spacing between them means additional work.

An embodiment according to claim 6, in which the profile of the respective hinge is simply cut perpendicular to the longitudinal direction is therefore preferable. In this case, the attachment has proved to be entirely sufficient.

It is recommended to place a plurality of screws in the longitudinal direction of the groove that tension the hinge fastener and the clip together (claim 7).

The arrangement according to the invention can be used according to claim 8 for a simple so-called two-part hinge, but also according to claim 9 for a three-part so-called hinge.

By sliding the shoe into the groove with the interaction of the different thrust surfaces, a certain fixation of the part of the hinge is provided against the torque acting in a vertical plane perpendicular to the plane of the frame. Unfortunately, it is not possible to prevent certain deviations during profiling, and the subsequent anodizing of possible further adjustments will not always be able to accurately keep the stated dimensions. Thus, there may be a situation where, for example, when the screw is fitted, the fastening part is jammed, thereby causing inaccuracies in the recess in which the hinge is clamped.

In order to prevent this, the arrangement according to claim 10 is suitable, in which projections and depressions are formed parallel to the longitudinal direction of the groove, which allow the fixing part to be clearly seated on the frame independently of any manufacturing deviations of the co-operating components.

The protrusions and depressions can be formed by ribbing or recesses. grooves according to claim 11.

The fastening parts are flat tape feet, which must be provided with depressions depending on the shape of the cooperating frame profiles. The existing hinge arm protrudes relatively far outward from the attachment point in the region of the screw up to the hinge pin. The loading of the hinge arm by weight acts transversely on the fastening piece, which is either in the form of a strip or a lamella. In the case of heavy sashes, it may happen that the fixing part bends slightly, the sash "hangs" and the gap between the fixed frame and the sash frame is larger than the lower one.

To avoid this phenomenon, the means according to claim 12 have proved to be suitable by means of which the fastening parts on the lower hinge of the sash can be pivoted so that the amount of gap between the fixed frame and the sash can be influenced.

-2 CZ 297727 B6

In particular, the means according to claim 13 may comprise at least one screw, which may be a set screw (so-called worm) to reduce the additional space requirement of claim 14.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a cross-section of a fixed frame 10 and a cross-section of a frame 20 of a door, window or the like, which in the embodiment consists of mutually identical extruded profiles 1 of aluminum. The bar profiles 1 have a rectangular cavity 2 inside, and grooves 4 having a cross-section C are pressed on their outer walls 3, which are opposite when the wing is closed, on the outer side of the bar 3. is not relevant to the present context.

The groove 4 of the cross-section C has a narrow rectangular cross-section transverse to the longitudinal axis of the profile 1, the longer side of which extends into the gap between the fixed frame 10 and the sash 20. The back side of the belly "C" is formed by the wall 3. C 'correspond to the shorter sides of the cross-section and are bent at the ends at an angle of 90 °, so that they form beaks 7, 7' facing each other and, if they meet, would form the other longer side of the rectangular cross-section. In fact, the beaks 7, 7 'have a through hole 8 of the same width, which is defined by the front sides 7 of the beaks. As can be seen in particular from Figure 2, the beaks 7, 7 'are parallel to the wall 3 and have a uniform thickness corresponding approximately to the thickness of the wall 3.

The wing 20 is pivotally connected to the fixed frame 10 by hinges 30 over the hinge axis A, which is vertical in the installed position. In the hinge parts 31, 35 of each hinge 30, a hinge pin, not shown here, is housed in housings that are fitted into corresponding recesses in these hinge parts 31, 35. The recess 19 is shown in FIG. 3.

-3 CZ 297727 B6

The anchoring of the hinge part into the profile groove and its attachment to the existing frame structure 1 will be described for the hinge part 35, but it will be understood that the attachment of the hinge frame part 31 is similarly formed.

The hinge part 35 comprises a hinge head 37 with a recess 19 and a fastening piece 36 that projects outwardly.

Adjacent to the outer side 9 of the beak 7 is the fastening part 36 of the hinge part 35 with the contact surface H. At the base of the beak 7 the bar profile 1 has a projection 12 in the side of the sealing groove 5 into which the corresponding projection 13 of the fastening part 36 fits. in a certain way, the angled shoe 38, which extends in the longitudinal direction of the perpendicular cross-section into the profile groove 4, and at its outer end 38, seen horizontally, abuts with its contact surface 14 formed at its outer edge to the inner side 15 of the opposite beak 7 '. The shoe 38 forms a step 16 on the contact surface 14, which fits into the face 7 of the beak 7 '. Thus, by means of the surfaces 13, 16, the fastening part 36 is fixed in a plane parallel to the wall 3.

At the same time as the fastening piece 36, a clip 40, which can be molded from sheet metal, interacts with a bar and is broken at one of the longitudinal edges facing the beak 7 by a distance 39 equal to its thickness and the thickness of the clip 40. 42 of the broken edge 41 abuts the clip 40 to the inner side 17 of the beak 7.

The inner side 44 of the flat unbroken opposite longitudinal edge 43 of the clip 40 abuts the outer side 18 of the beak 7 '.

The two co-operating portions 36 and 40 each adjoin the existing beaks 7, 7 'once from the outside and once from the inside. Thus, both parts must cross, as shown in Figure 2, in which the crossing region is indicated by a dash-dotted ellipse 49. To achieve this by symmetrical force application, the buckle 40 at the breakaway edge 41 is provided with a U-shaped recess 45, 4, the length of which in the longitudinal direction with the profile 1 corresponds to the height of the fastening part 36. The fastening part 36 can be inserted into the groove 4 by a shoe 38 and then a clip 40 can be fitted. above the fastening portion 36 and the portion 41 below the fastening portion 36.

As can be seen from FIG. 3, the shoe 38 in this embodiment with its opposite ends 38 'in the installed state in the vertical direction protrudes the fastening piece 36 longitudinally with the profile 1 in both directions, so that the shoe 38 is as long as the buckle 40 The U-shaped fitting 36 fits precisely in height.

In the exemplary embodiment, 3 through holes 46 are drilled in the longitudinal direction of the clip 40 and 3 correspondingly threaded holes 47 are provided in the longitudinal direction of the shoe 38. Screws 48 are screwed into the holes 46, 47 through which the fastening piece 36 and the clip 40 in the direction of the axis of the bolts 38, the beaks 7, 7 ' are caught between the fastening piece 36 and the clip 40 and are stabilized by force contact in the longitudinal direction of the L profile. for a guaranteed grip. As already mentioned, the fastening piece 36 and the clip 40 are pressed against the beaks 7, 7 'alternately, i. always from within and once from outside. By this arrangement, the fastening piece 36 can be inserted into the groove 4 on the right by the shoe 38 and then the clip 40 can be fitted over it without having to first insert it from the end of the groove 4.

To produce the hinge portion 35 of FIG. 3, a portion corresponding to the distance of the end faces 38 ' of the shoe 38 is cut from the extruded bar profile. Then, by machining, the right portion of the profile is cut according to FIG. 52, which are horizontal when installed and have a smaller distance to each other,

-4E 297727 B6 than the distance of the end faces 38 '. This machining is expensive. The hinge portion 135 of FIG. 5 is therefore simplified so that the bounding surfaces 51, 52 are parallel to each other over the entire hinge plan view, i.e. at the point of the shoe 38. This saves material and machining time. In this case, only two holes 46 are drilled in the buckle 140, which corresponds to two holes with an internal thread 47 in the shoe 38. Experiments conducted have shown that the attachment is not visibly disturbed.

Giant. 5 and 6 show the attachment of the hinge portion 135 for a simple two-piece hinge. Figures 7 and 8 show an alternative for a three-part so-called articulated hinge, where two hinge parts 135 with a gap are superimposed, which can be attached to the groove 4 of the profile by means of a correspondingly elongated buckle 142 with two recesses 45.

As can be seen from FIG. 2, the fastening part 36 has the hinge part 35 by means of the thrust pads 12, 13 and 13, respectively. 7, 16, although there is a well-adjusted position on the frame profile 1, there are nevertheless certain tolerances at the distances of said contact surfaces, which arise due to inaccuracies in the extrusion of the profile or in its surface treatment, e.g. anodizing. It may happen that in a vertical plane perpendicular to the plane of the frame, a situation may occur that will result in the hinge portion 35 being rotated to fit when the screw 48 is screwed. The hinge recess then does not align with the hinge and assembly problems may occur.

In order to ensure that the hinge portion 35 is independent of any tolerances with respect to the profile 1, the arrangement according to FIGS. 9 to 11 is proposed. Along the outer edge of the beak 7 formed on the profile groove 4 is formed by a longitudinal rib 57 of approximately semicircular cross section. which, when the shoe 38 and the fastening part 36 are inserted into the groove 4, fit into the additional groove 58 of the fastening part. The groove 58 is molded while extruding the profile to form the hinge portion 35. In the exemplary embodiment, the longitudinal rib 57 is located at the outer edge of the outer side 9 of the beak 7 and the groove 58 at a corresponding location of the contact surface 11 of the fastening piece 36. Of course, the longitudinal rib and groove may be opposite and have different cross section.

Giant. 12 shows a front view of a door with a fixed frame 10 and a sash frame 20 into which a heavy pane of double glazing 21 is inserted. The wing 20, 21 is mounted rotatably along a vertical axis of rotation on the fixed frame 10 by hinges 30, 30 , respectively. in the upper part of the wing 20, 21. The weight of the wing 20, 21 caused a partial " drooping ", i.e. the horizontal width 22 of the joint 12 between the fixed frame and the wing frame is greater than the corresponding width 23 at the bottom. This happens because the stress due to the weight of the upper hinge 30, which has a relatively extended arm in its lamellae, i.e. flat, shape of the fastening part 36 of the hinge part 35, bends slightly and pulls away from the adjacent frame 10 to the right, as shown in FIG. 2.

To prevent this, at least one "worm" screw 54 is supported in the lower hinge 30 perpendicular to the flat fastener 36 at a certain distance from the horizontal outer edge 38 of the shoe 38, which rests against the adjacent wall of the profile 1 and screwing causes the hinge portion 35 to rotate along the vertical axis of rotation lying near the horizontal outer edge 38 of the coulter 38 in the sense of the arrow 24 as shown in FIG. 14. Thus, the hinge portion 35 does not abut against the profile 1 so that the pin 29 of the hinge is displaced in the direction of arrow 24 and the gap 12 widens. By skewing the fastener 36 from the front with the bolt 54, the position of the lower hinge pin 29 in the sense of the arrow 24 as shown in FIG. 14 is shifted. This compensates for unwanted displacement of the hinge pin 29 at the upper hinge 30 caused by bending the hinge fastener 36. Surprisingly, it has also been found, in practice, that, when the joint width 23 is increased in the manner described, the joint width 22 also narrows spontaneously, resulting in a uniform gap 12 between the fixed frame. 10a of the wing frame 20.
