Abstract
Described is an ascent/descent device including: motion transmission means, a worm screw mechanism having a main axis of extension, a first nut and a second nut which are both configured to engage with the worm screw mechanism to move along the axis, a pulley positioned concentrically with the worm screw mechanism with the first nut, and elastic means interposed between the first nut and the second nut.
Claims8
An ascent/descent device, comprising:
- motion transmission means,
- a worm screw mechanism having a main axis of extension,
- a first nut and a second nut configured to both engage with said worm screw mechanism to move along said axis,
- a pulley positioned concentrically with said worm screw mechanism to rotate about said axis of said worm screw mechanism, said pulley being driven by said transmission means so as to slide said first nut along said axis according to said ascent/descent direction;
- elastic means interposed between said first nut and said second nut, and connected at one end to said second nut, in such a way that the feeding of said first nut along said mechanism withdraws with it said second nut, wherein:
- a) said first nut being of the reversible type, for descending along said axis according to said ascent/descent direction without being fed by said transmission means, and
- B) said second nut being of the irreversible type, for descending along said axis according to said ascent/descent direction only when fed by said transmission means.
