Abstract

L'invenzione riguarda una struttura protettiva (9), associata ad una unità operatrice (1) comprendente una porzione mobile (3, 7) dotabile di movimento nei due sensi secondo una direzione rettilinea (F); la struttura protettiva (9) comprende due mezzi di supporto (12, 13) girevoli folli attorno a rispettivi assi paralleli fra loro e normali alla direzione rettilinea (F), supportati all'interno di rispettivi corpi scatolari (10, 11) collegati alla porzione mobile (3, 7) e disposti da bande opposte rispetto alla porzione mobile (3, 7) stessa con riferimento alla direzione rettilinea (F), due tapparelle (18, 19) rispettivamente avvolgibili attorno ai mezzi di supporto (12, 13) e presentanti una propria rispettiva prima estremità collegata al relativo mezzo di supporto (12, 13) ed una seconda rispettiva estremità collegata ad una struttura fissa (8) dalla quale é supportata, mezzi cinematici (14, 15) di collegamento reciproco dei mezzi di supporto (12, 13), e mezzi compensatori (29) interposti ed agenti tra i mezzi cinematici (14, 15) ed i mezzi di supporto (12, 13) ed atti ad eguagliare le velocità periferiche dei tratti delle tapparelle (18, 19) avvolti attorno ai mezzi di supporto (12, 13); i tratti delle tapparelle (18, 19) non avvolti attorno ai relativi mezzi di supporto (12, 13) si sviluppano almeno parzialmente secondo un piano parallelo alla direzione rettilinea (F).(Figura 2).
