Description

GERMAN

The invention relates to a rotating rod oar lock for windows and doors with a profiled Rotary rod, at the ends of which a catch hook is arranged.

The parts of the known fittings are preferably delivered individually, so that storage is possible. The fitting parts are assembled in the workshop, depending on the respective The size of the window determines the exact length of the pivot rods and which are available in stock lengths Rotating rods are adapted to the respective sash heights by simply cutting them off.

In a known rotating rod oar lock, the catch hook is by means of a screw on the Rotating rod held. Due to the torsional stress on the catch hook, the screw loosens so that the catch hook can come loose from the rod.

In another known catch hook, a clamped sleeve is arranged; by the clamping effect however, rigid, reliable attachment is not achieved.

The object of the invention is to fix the catch hook on the rotating rod with the workshop assembly to enable usual means, in particular the catch hook of a rotating rod oar lock to train so that it can be reliably and stably attached to the rotating rod and that the assembly can be done quickly and easily.

According to the invention this is achieved in that the catch hook which can be pushed onto the rotating rod has a protruding laterally over its recess and opposite the upper edge of its recess has higher limit stop and that the protruding head end of the rotating rod like a rivet head is driven over the edge of the recess.

In the drawing, the rotating rod oar lock according to the invention is shown in an example. It shows

On the profiled rotating rod 1, the rudder 3 is arranged by means of a rigidly attached bracket, which swings vertically about the pin 3 α. The rotating rod 1 is rotatably held by central guide members 4 and by guide sleeves 5 which are attached to the casement B. At the ends of the rotating rod 1, the catch hooks 6 and sit

on the fixed frame A of the end pin 7. A bracket 8, which is attached to the wing frame B , has a pressure surface 8a and pin Sb for the rudder 3. The catch hook 6, which has a recess

ao is provided in accordance with the cross-section of the rotating rod profile, has a limit stop 6 a, which is offset higher than the upper edge of the recess, which determines the total length of the fitting and the correct position of the catch hook 6 with the rotating rod length and which enables rigid riveting to the rotating rod 1. The catch hook 1 is pushed up to the limit stop 6 α on the rotary rod 1, and the head end of the rotary rod 1 protruding over the edge 1 b of the recess of the catch hook 6 is driven with a few hammer blows over the edge 1 b of the recess like a rivet head, so that the catch hook 6 is held between the limit stop 6 a and the rivet head-like protrusion of the head end of the rotary rod 1.

Claims (1)
