Abstract

This gate opening and closing mechanism is fixed into a trench in the ground, directly under the tracks of two sideways sliding gates. It consists of a horizontal shaft with square profile left- and right-hand screw-threads. Two threaded bronze collars are mounted on the shaft, one connected to the left-hand gate and the other to the right, so that the gates move in opposite directions when the shaft is rotated. The shaft is driven by a chain. The latter runs around a sprocket on the centre of the shaft and another runs on the output of a 10:1 reduction gearbox. The reversible 1/3 h.p., 1400 r.p.m. electric motor which drives the gearbox is controlled by a pushbutton via a relay and gate end-stop switches. For safety reasons the relay is powered by 12 volts obtained from the mains via a transformer.

   Omschrijving van de uitvinding voor : Mecanisch ondergrondse Poort-of Hekkenopener (en-of sluiter) Deze bestaat uit een as met vierkante schroefdraad links-rechts, aangedreven door een electrische motor, via een reductie-kast. 



  Op deze schroefdraad komt links en rechts een metalen moer, waarop de arm bestemd voor het openduwen of toetrekken is gemonteerd. 



  Door de beweging van de as, aangedreven door een   electrische motor, verwijde-   ren de twee moeren zich van elkaar of komen ze naar elkaar toe, volgens de gegeven instructie.

   Description of the invention for: Mechanical underground gate or gate opener (and / or shutter) This consists of a shaft with square thread left-right, driven by an electric motor, via a reduction box.



  A metal nut is mounted on this thread on the left and right, on which the arm intended for pushing or pulling is mounted.



  Due to the movement of the shaft, driven by an electric motor, the two nuts separate or come close to each other, according to the instruction given.
