End stop part for gel teat rods from joint rod rolls & den.

The invention relates to an end limit part for joint rods of hinged bar roller shutters to prevent transverse movements of the hinged bars to each other, one by means of Querlasohc Long head plate that can be attached to the Uerz joint rod having.

As such shifted Gelenkstübe located at Abwärtslaufon of the curtain on the inlet funnel of

Put on the guide rail and were damaged 1st the prevention of such transverse movements is urgently required

The invention is based on the problem of the known To form the end stop part for the hinge rods in such a way that that it only fulfills the purpose mentioned at the beginning, but also contributes to the fact that it does the right thing the itolladens-related frictional resistance is kept very low

This task is solved according to the invention that the head plate is provided at least on the side facing the roller shutter roller with at least one freely rotatable roller slightly protruding over the head plate fly 1st. Duron such an arrangement is wear and tear The floor-limiting parts are significantly reduced, because when the roller shutters are moved up and down, their entire outer surface is not subject to structural elements and coverings. For the rest, let "the shutters due dttes reduced frictional resistance fled ^r lt less force Act on effort than before. The RoI ¹ ^ a come into action, for example during the upward movement of the roller shutters, especially when the hinged rods emerge from the vertical guide rails before they run onto the roller shutter roller, and as a result of the inclination to the roller shutter roller with a certain pressure, which depends on the size and height of the roller shutter and can be significant for roller doors can slide over the upper inlet funnel of the guide rails. This sliding under load, which occurs in reverse direction when lowering the roller shutter, but takes place in the same way as with the upward movement, brings a large frictional resistance with it,

if the top plate of the end delimitation part is flat rests against the inlet funnel of the guide rail. In contrast, the roles according to the invention on the When the top plate is attached, it is converted into rolling friction, which not only has a favorable effect on wear and ease of movement, but also has a positive effect Booh prevents the oil control rods from jamming in the critical phase of their movement

In the drawing, an exemplary embodiment of the invention is shown in a simplified manner. Show it*

The joint rod is guided in a Hindu way and pushed on so far, until the tab 6a engages behind the joint rod end and the entire end delimitation part 3 is firmly seated. The attachment the head plate on the hinge tab can also be in be met in a different way.

On each 2nde of the head plate 4, rollers 7 are freely rotatable and can be made of any material. Plastic rolls are expediently used, preferably made of polyamides (trade name "nylon"), which are fitted into an end delimitation part 3 formed from a similar or the same material, as long as this is not completely hardened. The rollers 7 protrude slightly over the top plate and cause it to slide not flat, but rolling in the guide rail 2 and in particular in the inlet funnel of this guide rail, which reduces wear and tear and increases the speed of the roller shutter.

Deviating from the drawing, more or fewer rollers than shown can be used. For example , it is possible to provide an additional roller 7 which rolls on the sole wall 2a (Fig. 3) in order to additionally reduce friction on the end face of the head plate 4. In the case of head plates that are not curved, a single roller may be sufficient, but to achieve the desired purpose care must be taken to ensure that this is located on the side of the head plate facing the roller shutter roller.
