EP0409767B1 - Rising hinges for a gate - Google Patents

Abstract

A rising fitting for a gate, having a device for the simultaneous raising or lowering, occurring together with rotation, of the end of the gate facing away from the rising fitting, the rising fitting consisting of an upper and a lower hinge. The technical problem is to provide a rising fitting which makes do with few parts and which at the same time works reliably and in a functionally safe way. The two hinges (2, 3) are equipped with a ball joint (7, 14). The line of projection of the straight lines connecting the ball-joint centres of the two hinges onto the horizontal plane intersects the gate surface at an angle of 45 DEG . And at least one ball joint (14) is adjustable along the line of projection. <IMAGE>

Description

The invention relates to a lifting fitting for a door with an upper and a lower hinge for simultaneously lifting or lowering the end of the door facing away from the lifting fitting, a bracket plate attached to a longitudinal side of the goal post of one hinge forming the closed door surface at an angle of 45 ° intersecting adjustment line for a pivot pin. Gate is understood to mean any plate-shaped rotatable part for closing an opening or a passage.

EP-A1-0 012 677 describes a lifting fitting of the type mentioned. The adjustable hinge has an adjustable intermediate part so that the gate wing is vertical in the closed position and in the 90 ° open position. As a result, the hinge adjustment is lengthy and easily adjustable.

The object of the invention is to provide a lifting fitting that requires only a few parts, can be adjusted quickly and precisely and works reliably and reliably.

This object is achieved according to the invention in that both hinges are provided with a ball joint, that said adjustment line has a plurality of holes for adjusting the hinge, that the band of the hinge has corresponding holes for a fastening pin of the socket of the ball joint and that the holes have the same distances from each other in the console plate and in the section.

The invention differs from the prior art in that the ball joints ensure reliable function and the mutual arrangement of the ball joints ensures that the gate wing is aligned vertically in the closed position and after opening by 90 °. With further lifting or lowering, swiveling by 180 ° is possible.

In order to ensure a problem-free adjustment of the lifting fitting, it is provided that the section of the band having the holes is oriented parallel to the said adjustment line in the closed position of the gate.

A continuous adjustment is possible in that the holes in the console plate are designed as an elongated hole-shaped opening and in that the ball joint sits on an adjusting spindle of the band.

The console plates sit on a long side of the post, which is aligned parallel to the door surface when the door is closed. Only holes on the one hand in the console plate and on the other hand in the hinge leg of the hinge in question are required for the adjustment. The setting is thus possible in stages, which is completely sufficient in practice and offers advantages in terms of simple construction. The design and arrangement of the console plates enables the door to be opened beyond an angle of 90 ° to a position of 180 °. This opening is desirable in many cases. However, it cannot then be ensured that the door surface is aligned vertically in the open position. If the gate is to be raised when opening, the lower hinge has the displacement and adjustment of the ball joint. The upper hinge can also be designed accordingly. Then the gate is lowered when opening.

Fig. 1 shows a goal post 1 with a goal 4. At the goal 4, an upper hinge 2 and a lower hinge 3 are provided, both of which are equipped with a ball joint 7 and 14, respectively. The ball joint 7 sits between a bracket plate 5 and a band 6. The bracket plate 5 is attached to the goal post 1 or a gate pillar. For the lower hinge 3 there is a bracket plate 9 on a molded part 20 with an elongated hole-like opening 21, in which the ball joint 14 is anchored with a threaded bolt 22. On the ball joint 14 there is also an adjusting spindle 23 which is mounted on the band 10 so as to be adjustable in the longitudinal direction.

Fig. 2 shows the gate 4 in the open state, the pivot points being the respective ball joints. When opening, the lower hinge swivels around the ball joint with a radius that is equal to the effective length of the adjusting spindle. On the one hand, the door is pivoted away from the goal post by the length of the adjusting spindle and raised accordingly. After pivoting through 90 °, the door is again in a vertical plane, which is desirable in many cases.

The same adjustment can also be provided for the upper hinge.

3, the goal post 1 has a square cross section and is aligned with an edge on the goal 4. A metal bracket 24 as a console plate 9 sits on a long side of the goal post 1. A narrow goal post, and thus a short opening, is sufficient in particular for small terrain climbs.

In Figures 4 to 7, a right-angled goal post 1 made of metal is shown broken off in order to be able to represent the hinges on a larger scale. There is an upper hinge 2 and a lower hinge 3, which carry a gate 4, of which a frame bar is shown essentially.

The upper hinge 2 comprises a console plate 5 and a band 6. Both hinge parts are pivotally connected to each other by a ball joint 7. In the case of a gate in metal construction, the console plate 5 is welded to the gate post 1 and, accordingly, the band 6 to the frame of the gate 4. However, you can also attach a band leg 8 to the band 6, which is then screwed to a wooden gate can be, as indicated in Fig. 7.

The lower hinge 3 also consists of a bracket plate 9 and a band 10. The bracket plate 9 has a number of holes 11. The holes 11 are arranged on a straight line and aligned at an angle of 45 ° to the side face of the goal post 1 and thus to the goal face in the closed position of the goal 4. The band 10 has a section 12 which, in the closed position of the gate, extends at an angle of 45 ° to the gate surface, as can be clearly seen from FIG. 6. In this section 12, a plurality of holes 13 are provided, which are arranged at the same distance as the holes 11 and are aligned with the holes 11. The console plate 9 and the band 10 are connected to each other by a ball joint 14. The ball joint 14 has two fastening pins 15 and 16. The fastening pin 15 is inserted according to the required slope of the gate when opening in a hole 11 of the console and fastened by a screw connection. The fastening pin 16 is inserted into the corresponding hole 13 in the band 10.

In the drawn orientation of the ball joint 14, the gate 4 reaches the greatest slope when opening. The hole 111 is approximately aligned with the axis of the ball joint 7 of the upper band, so that when the ball joint 14 is adjusted to the hole 111, the gate is pivoted horizontally when opening.

If you swap the top and bottom hinge, you can ensure that the gate is lowered when opening, which is desirable in some cases.

The lifting fitting according to the utility model consists of bent sheet metal parts, which are each connected by a ball joint. The setting is made by arranging the ball joint in the holes provided. This results in a very simple and safe construction. The hinge parts can be welded to a metal structure. In another way, screwing to a wooden structure of the gate is also possible.
