Pivot bearings or hinges, especially for metal doors

Pivot bearings or bands, especially for metal doors, are known in various designs. There is Constructions that are screwed to the upper or lower edge of the IThang frame with a lifting lever. It Designs are also known in which correspondingly short metal ends on the one hand with your frame and on the other hand, with the sash frame in silence, Furthermore, constructions are also known that on the narrow sides (inside or outside edges) of the frame or sash frame be attached.

In all known designs, however, the lower pivot bearing, which bears the main load of the door, is only for the right or left-hinged (yours can be used.

The hiring is based on the task of a door bearing construction to create, in which both the upper and the lower pair of pivot bearings by simply repositioning on the right like can be used on the left.

This is achieved after the firing by all four ropes to be "attached" to the frame or sash frame "two pairs of camps (! rag- and leadership si age r) for their own horizontal center plane are designed to be folded symmetrically.

Further characteristics and features of the moat emerge from the subclaims and the following description of advantageous, exemplary embodiments.

üls show:

üg.1 the upper pair of bearings after the! price increase for welding on the frame,

Jig.2 the lower pair of bearings for welding, ! ig.3 shows a vertical section through the pair of bearings

den! ig.5 and 6,
! ig.4 a diagrammatic representation of an insert bushing

for bearings according to! ig.3,5 and 6,! ig. 5 and 6 on screwable pivot bearings, and z? / Ar partially cut horizontally.

The key to the solution for welding is to that in the lower bearing pair of bearings to be arranged below, to be welded to the frame with a central bore and two-sided concentric grooves is provided for receiving a roller bearing 2 (axial bearing).

A stepped bearing pin 4 is inserted into this lower cable 3

used, depending on the use as a right or left Bearing with one or the other side of the recess 1 is kept silent.

Since the upper part 5 of the lower support bearing is also around its horizontal center plane is designed to be folded symmetrically is, so the [drag bearing according to Pig.2 can be used as a right or left bearing can be converted.

To secure against subsequent lifting of the (Eür is a known cover plate screwed to the bolt 4 is provided.

The hiring at the job leadership camp according to Üg.1 for the The weld-on solution consists in the fact that the cable to be arranged above and provided with a longer weld-on tab is also provided a pressed-in or somehow fastened liner 7 made of a particularly good sliding material, such as Bronze, brass, certain plastics or the like. owns.

This upper guide band can also be seen in a more familiar manner Way by turning the guide pin 8, which is in the lower Rope by welding, cross bolts or the like. is attached, are used for suras posted on the right and left »

The screw-on solution according to Figures 3 to 6 also has one to be attached to the frame or the frame, shorter screw-on tabs 9 and a longer one on the hill

frame to be screwed on 1o. The upper (leadership) bearing and the lower (supporting) bearing are the same in this version. They all have a sliding bearing bushing in the lower rope (9) 11 according to Jig. 4 made of plastic, brass, bronze or the like. and one, in the upper part by cross bolts or the like. to be fastened pivot pin 12 made of metal, plastic or the like «

üJine further! Price increase of this version according to Fig.3-6 consists in that the Ansehraublappen are provided with one, two or more cylindrical lugs 13 or 15, which for attachment, in a corresponding hole of the Blendbzw. The wing frame can be used. This eliminates the previous annoying clinking work necessary for screw-on bearings. All you need to do is drill one or more holes to T / earth, the axial forces of the I3? ür are nevertheless absorbed by sufficiently dimensioned cross-sections.

Fig. 5 shows an embodiment in which in the preferably Light alloy bearing part 9.1 ο two threaded bushes each 13 are used, which are preferably made of steel in light metal bearings to provide the necessary [drag forces to be able to catch.

You T / ground in two or more adjacent ones Holes introduced. The tensioning with the frame or casement is made by two from the other side in Threaded screws to be used in this frame 14. Through this

_ 5 -

Solution , the bearings can also be used for slurry pipes of different widths in one design.

The construction according to Mg. 6 has one on the aluminum part turned, cylindrical shaft 15, which / inserted into a large bore in the wing tubes and similar Way like Toei of the construction according to Fig.5 of the other Side fastened with one, two or more threaded screws will.

The sliding bearing bushing 11 according to Mg. 4 is two ckmäs si gerweise so ::, executed that they both have a radial guide opposite the 3 guide bolt 12 as well as an axial Druckaufnahnie made possible by a collar 16 compared to the upper bearing part.

In addition, one or more tilts are provided to prevent rotation on the lower cylinder circumference (Mg. 4-).

Claims (4)

P.L 591210 »J-i I-, Sch with z claims 1. Pivot bearings (hinges), especially for single-action doors, windows and the like., characterized in that all four on the blend "or. Sash parts to be attached to the two pairs of bearings (Support and guide bearings) to their own, horizontal The central plane is hinged-dimensionally * 2. Pivot bearing according to claim 1, characterized in that the weld-on or screw-on tabs of a pair of bearings are designed differently, in such a way that the shorter fastening flap for each pair is under the longer lobes are arranged and to the optimal pivot point mass of the upcoming locks is. 3. Pivot bearing according to claims 1 and 2, characterized in that in each case one half of a pair of bearings an additional G-guide in the form of an axial and / or Radially receiving slide or roller bearing is provided Ofig.1,2,3). 4. Pivot bearing according to claims 1 to 3, characterized in that one or more, Cylindrical ones protruding into the misery or surfing frame Approaches to absorb the load capacity are provided, which are arranged transversely to the door level and on the Rotation point facing away with threads for receiving the introduced from the other side of the door or window frame Fastening screws are provided (Fig. 5,6).
