Description

The invention relates to a Zargenholm a frame of doors or gates with a fastening device according to the preamble of the appended claim. 1

Frames serve to hold a door leaf at the door opening of a masonry. For this purpose, frames usually have at least three Zargenholme, which are connected to each other such that two vertically arranged Zargenholme vertically and are arranged parallel to each other and connects at least one horizontally arranged Zargenholm the two vertical Zargenholme in the transverse direction. The door leaf is usually hung on one of the vertically arranged Zargenholme means door hinges. Further, the cross sections of many frames have a fold, which is formed as a gradation and points in the direction of the door leaf to form a stop surface for the door leaf in the closed state.

Frames are usually made of wood or metal, especially steel, with most commercially available frames made of metal, especially steel. The focus is on these steel or metal frames.

To attach the frames to a soffit in a masonry different attachment methods can be used. Depending on the circumstances encountered different fasteners used. In most cases, the attachment of the Zargenholme takes place at the wall reveal with screw fastening. For this purpose, the Zargenholme usually have openings through which a screw fastener is passed and connected to the wall reveal. To fix the screw fasteners in the wall reveal holes are drilled in the soffit and these provided with dowels. Subsequently, the frame beam is positioned with its hole in front of the drilled hole so that a screw can be inserted through the opening of the Zargenholms and screwed into the hole.

In particular, in the attachment of Eckzargen it is often desirable to introduce the Schraubbefestiger obliquely in the wall reveal, so as to position the Schraubbefestiger as close to the door stop area of the frame spar. By an oblique attachment of a wall anchor, such as in particular a dowel Schraubbefestigerkombination you can penetrate even with a near the edge of the door opening point of attack with the dowel further in the middle of the soffit and thus achieve a total of a stronger attachment.

The wedge device 24 has two wedge elements 32, 33, wherein one of the wedge elements is a fixed wedge element 32 fastened to the profile of the frame spar 10 and the other is a wedge element 33 which is displaceable relative to the fixed wedge element 32.

The fixed wedge element 32 comprises a wedge region 34 and a stop region 36. The stop region 36 is rectangular in shape, with one side abutting the leg region 18. Accordingly, the stopper portion 36 serves to fix the fixed wedge member 32 to the leg portion 18 and increase the force introduction area. The wedge region 34 has seen from the side (in the longitudinal direction of the Zargenholms) in the form of a right triangle, which has a corresponding hypotenuse 44, a Gegenkathete 46 and an Ankathete 47. In the counter-catheter 46 surface facing a recess 37 is introduced, which has a front recess portion 38 and a rear recess portion 39. The rear recess portion 39 is provided with an internal thread. About the recess 37, a fixing member 40 is inserted with an external thread in the wedge region 34 such that the fixing member 40 is screwed to the rear recess portion 39. By turning the fixing element 40, the fixing element 40 are moved in the direction of the movable wedge member 33. Advantageously, the fixing element 40 can rotate over the front opening area 38.

In the hypotenuse 44 facing surface a T-shaped guide groove 52 is introduced. Left and right of the guide groove 52 each have a support surface 48 is provided, which is provided with a detection device 41. The detection device 41 has a plurality of teeth 42, as in FIG FIG. 1 shown.

The slidable wedge member 33 is approximately formed as a right triangle and includes a hypotenuse 44, a counter catheter 46 and an Ankathete 47. On its hypotenuse 44 facing surface, the sliding wedge member 33 has a T-shaped guide member 50, the shape of the T -shaped guide groove 52 corresponds. Left and right of the guide member 50 each have a support surface 48 is arranged, which has a detection device 41 in the form of teeth 42.

The two wedge elements 32, 33 are arranged relative to one another such that the displaceable wedge element 33 engages with its guide element 50 in the guide groove 52 of the fixed wedge element 32. Accordingly, the slidable wedge member 33 is slidable in only one direction with respect to the fixed wedge member 32. The two bearing surfaces 48 of the wedge elements 32, 33 lie on one another and the teeth 42 of the respective detection device 41 engage with each other. The displaceable wedge element 33 rests against the masonry 12 with a masonry-side abutment surface 54 corresponding to the abutment 47. Accordingly, by moving the displaceable wedge element 33, a contact of its masonry-side abutment surface 54 on the masonry can be achieved.

The bearing element 56 is disposed in the wall reveal portion 16 of the Zargenholms 10 and provided with an internal thread. In the internal thread, the threaded screw 60 is screwed, wherein at the end of the non-screwed portion, a support member 62 is arranged, which can be applied to the masonry 12. At the point at which the threaded bolt 60 protrudes from the bearing element 56, the lock nut 58 is arranged so that by turning the lock nut 58, the threaded screw 60 in the direction Masonry 12 is slidable. Accordingly, the threaded screw 60 can be adapted to a present between the Zargenholm 10 and the masonry 12 distance.

The recess 28 with the centrally located through hole 30 is disposed between the wedge device 24 and the pin member 26. The recess 28 is formed so advantageous that it can accommodate the head of the inclined fastener 31 completely. Accordingly, the recess 28 may be provided with a sealing plug, so that an outwardly visually appealing appearance of the frame spar is ensured. About the inclined passage opening 30, the fastening element 31 is connected obliquely to the masonry 12.

How good of the Fig. 3 and Fig. 6 As can be seen, the bottom of the recess 28 is arranged approximately parallel to the mutually engaging sides of the wedge elements 32, 33. The passage opening 30 is therefore arranged with its central axis approximately perpendicular to these mutually engaging sides of the wedge elements 32, 33, ie here the hypotenuses 44. As a result, the wedge device 24 securely supports fastening forces.

In the following, a possible procedure for mounting the frame spar 10 to the masonry 12 will be described. For this purpose, an oblique hole is first introduced into the masonry 12 and provided with a dowel. Subsequently, the Zargenholm 10 is positioned in front of the introduced into the masonry hole 12, that the passage opening 30 is aligned with the hole in the masonry 12. Next, the slidable wedge member 33 is displaced relative to the fixed wedge member 32 such that the slidable wedge member 33 abuts the masonry 12 with its masonry side support surface 34. To fix the displaceable wedge element 33, the fixing element 34 is moved in the direction of the guide element 50 by rotating in such a way that a frictional connection is created between the fixing element 40 and the guide element 50. By a combination of the positive engagement of the teeth 42 of the fixed wedge member 32 and the displaceable wedge member 33 and by the non-positive fixing of the guide member 50 by means of the fixing member 40, a strong fixation of the position of the displaceable wedge member 33 takes place. Also, the support member 62 of the threaded screw 60 at brought to the masonry to the plant. For this purpose, the lock nut 58 is rotated in such a way that the threaded screw 60 moves in the direction of the masonry 12, until finally the support element 62 frictionally rests against the masonry. Finally, the fastener 31 is inserted into the recess 28 and bolted to the dowel in the masonry 12. For the stable fixation of the Zargenholms 10 to the masonry 12 a plurality of fasteners 31 are provided so that a Zargenholm has a plurality of fasteners 20.

Accordingly, the spacer elements 22 are adapted to be provided between the frame beam 10 and the masonry 12 distance.

The fastening device 20 shown here is characterized in that, as a result of the two spacer elements 22, a torsionally rigid mounting of a frame spar 10 on a masonry 12 is made possible by means of a slanted fastening element 31. In addition, the central arrangement of the recess 28 between the pin member 26 and the wedge means 24 allows advantageous support of the frame spar 10 to the masonry 12 during assembly. As a result of the adjustable spacer elements 22, the fastening device 20 can be advantageously adapted to the respective installation situation. Furthermore, the recess 28 ensures a visually appealing appearance, since the head of the fastener 31 is received in the recess 28 and the recess 28 can be provided with a sealing plug. Similarly, the pin member 26 ensures a simple adaptation of existing between the masonry 12 and the frame member 10 distance to compensate.
