Abstract

Αρπαγες ανελκυστήρων (1) που αποτελούνται από πλακίδια τριβής (2) ιεραρχικού βιομιμητικού μοτίβου επιφάνειας τεσσάρων γεωμετριών εκτεταμένης κηρήθρας (5), κηρήθρας (7), κηρήθρας με κηλίδες (9) που ακολουθεί τη μορφολογία των πίσω ακρών ενός βατράχου και του ελαστικού αυτοκινήτου με βιομιμητικό σχεδιασμό (11) αναπτύχθηκαν με στόχο να ακινητοποιήσουν ομαλά τον ανελκυστήρα (4) μειώνοντας την πιθανότητα τραυματισμού των επιβαινόντων και αποφεύγοντας την ολική καταστροφή τους από την τριβή ώστε να αποφευχθεί η αντικατάστασή τους.Elevator grippers (1) consisting of friction plates (2) of a hierarchical biomimetic surface pattern of four geometries of extended honeycomb (5), honeycomb (7), honeycomb with spots (9) that follows the morphology of the rear ends of a frog and a car tire with a biomimetic design (11) were developed with the aim of smoothly immobilizing the elevator (4) reducing the possibility of injury to the occupants and avoiding their total destruction by friction in order to avoid their replacement.
