against lifting with the door open.

The present invention relates to a device for securing the hinges which can be lifted out with doors that open on both sides against lifting when the door is open.

The accompanying drawing shows a safety device provided with the aforementioned safety device Door in

Fig. 1 in view with partial section, in Fig. 2 in horizontal section and in

Fig. 3 shows in vertical cross section.

4 to 8 show the upper left hinge in different views and sections together with the locking device and

9 shows the latter in plan view.

The construction of the double-sided opening door with releasable hinges is probably known and should only be briefly described here for the sake of completeness, in order to follow up on it to make the new easier to understand.

Such doors are known to have four hinges that can be released in this way, two of which are each symmetrically constructed and arranged at the same height on both sides of the door.

Each of the hinges consists of three parts, the pivot bearings aa ¹ (or a ² a ³ ) mounted on the door frame, the guide sleeves bb ¹ (or b ² b ³ ) attached to the door and the lever cc ¹ (c ² c ³ ) supported pivot dd ^l (or d ² d ³ ).

The levers cc ² and C ¹ C ^{3 of} the hinges located on one side of the door sit on a common, respectively in a next to the blow bar e. e ¹ located groove of the door up and down sliding rod // ¹ , which is operated by the locking mechanism.

This Bethätigung of the push rods (FF ¹⁾ is likewise in a known manner by in recesses / ^2/3) of the push rods / (f ¹⁾ engaging thumb h ² (h to be moved through the buckle k (k ^l) Drückernufs ³⁾ h (h ^l ), which, when the buckle k (k ^l ) is pressed down, lift the rod f (f ¹ ) and release the associated pivot pins d d ' ² (d ^l d ³ ) from their bearings, so that the door now around the pins d ¹ d ³ (dd ² ) the other side rotated, so it can be opened. The return movement of the pins after releasing the pusher buckle k (k ¹ ) is also effected in a known manner by a spring m (m ¹ ). ■ Inclined sliding surfaces η η ² (U ¹ Ti ³ J of the angular bearings facilitate the lifting of the pin when the door is slammed for the purpose of closing.

The handle sockets of both locks are connected to one another by levers k ² (k ³ ) and a common push rod ρ , so that when on one. Buckle a downward pressure is exerted, the buckle on the other side must move upward and the hinges on both sides of the closed door cannot be lifted out at the same time.

In order to prevent the door from being opened on one side when the other side is not yet closed, according to the present invention in each of the

two upper bearing shells α fa ¹ ) a so-called snapper q (q ¹ ), ie a non-equilibrium lever rotatable about fixed point q ^{2 fq 3} j , which with a tooth-like extension q * (q *) (see FIG. 9) into a tooth gap r ² for ³⁾ of a ¹⁾ attached or with such a piece-forming disc r fr ¹⁾ engages; so that r on the lever c (BEZW. c when turning the door around one of fishing by the rotation of the disc for ¹⁾ of the snapper q (q ^l ) is forced to swing out.

The part facing the inside of the shell α fa ¹ ) lies over a wedge-shaped extension c ⁴ fc ^s ) of the lever c fc ¹ ) and thus prevents the latter from being lifted.

But since c at full 'Oeffhen the door (at 18o °, strichpunktirte position Fig. 7) of the wedge socket ⁴ (c ¹⁾ is moved away under the snapper q (q ^1), the device is made of the DAF. upper hinge d (d ¹⁾ carrying widened lever c fc ¹⁾ itself fa of the associated Angel shell α fa can in a section a ^{5 6) 1)} occur, namely even before the wedge approach c ⁴ fc ^b) the catch q (q ¹ ) runs, whereby one hinge is secured at all times by being released (provided that the door is open).

So that any twisting of the catch q (q ^l ) (when the door is open) does not result in the hinges jamming when the door is closed, it is fixed in its swinging movement by the shell wall on the one hand and by a pin s fs ¹ ) on the other is brought back into the normal position (Fig. 5 and 9 fully drawn position) each time the door is closed by a raised attachment c ^e fc ¹ ) on the wedge extension c ⁴ fc ⁵ ).

As far as possible malicious interventions are concerned, this is essentially controlled by the fact that springs, which are known to form the most delicate part of a mechanism, are avoided, and the only volute spring m fm ¹ ) is let into the door and by one with the lever c fc ¹ ) a piece forming or attached to this plate t ft ¹ ) (Fig. 8) is covered.

Against being lifted off its hinges, the door can be provided with a strip or Rail above the door (not shown in the drawing) must be secured.

The drawing shows a wagon door as an example, but it will open Use construction for all kinds of doors, as well as in relation to them in general its shape and dimensioning of the individual details can be changed at will without that something would be changed in the essence of the invention.
