Rolling screw (1) comprising a first threaded male member (6), a second threaded member (3), means (5) that permit said second threaded member (3) to rotate freely in relation to the housing (2), as well as means (7) that permit to maintain fixed and constant the position of the axis of said first threaded member (6) in relation to the housing (2). Means of synchronisation are also foreseen for the relative rotation between said first member (6) and said second member (3). Said screw is characterised in that at least one of the two threaded members presents a threading conformation such to permit the transmission of the rotation motion to another element without relative tangential sliding action.

This invention concerns a rolling screw with smaller advance per turn than the pitch of the threading, characterised in that a threaded coupling is foreseen in which a screw (1) is turned inside one or more female screws inserted in a single body or sleeve (2) and where the pitch of the thread of said female screws is equal to that of the screw (1), whereas the nominal diameter is greater than that of the screw itself.

The invention concerns a so-called fold-away bed, to be used in the fields of camping, seamanship, furnishing of bedsits and in all other dwellings where there is a lack of space, for which reason the components of the furniture must take up a minimum amount of space. Such a bed is characterised in that, in rest state, it is lifted until it comes into contact with the ceiling of the room in which it is inserted. In the dependant claims of the finding there are also special means that allow said bed to be moved.

The present invention provides a quick connection and/or fastening system suited to bring a first element (P) and a second element (S) to a first configuration of connection and to a second configuration of disconnection; the system comprising a first component (10) and a second component (20) suited to be respectively mounted on the first and on the second element (P, S), the first and the second component (10, 20) being furthermore suited to be brought to a first configuration of connection and to a second configuration of disconnection, in such a way as to alternatively allow the mutual connection and disconnection of the first and of the second element (P, S). The first component (10) is suited to house a terminal portion (21) of the second component (20) in such a way as to allow it to translate inside it. The system comprises rolling means (22). The first component (10) comprises a first rolling surface (12a) for the rolling means (22) and the terminal portion (21) of the second component (20) comprises a second rolling surface (21a) for the rolling means (22). The rolling means (22) are suited to counteract the translation of the terminal portion (21) of the second component (20) towards the configuration of disconnection of the system and are suited to be set rotating in a first direction of rotation by the translation of the terminal portion (21) of the second component (20) in order to reach the configuration of connection of the system, and suited to be set rotating in a second direction of rotation, contrary to the first direction of rotation, by the translation of the terminal portion (21) of the second component (20) in order to achieve the configuration of disconnection of the system. The system is such that the second rolling surface (21a) is configured in such a way that, in the configuration of connection, the distance between the second rolling surface (21a) and the first rolling surface (12a) increases along the direction of translation of the terminal portion (21) that leads to the configuration of disconnection of the system.
摘要:
A steering wheel for a boat rudder, which can be mounted on a rudder actuating shaft, comprising a substantially circular body (2) with an external peripheral edge (3) for gripping by a user and a central hub (4) defining an axis of rotation (L), characterized in that the body (2) is formed by a plurality of circle portions (5) which are movable with respect to each other, so as to pass selectively from an open operative configuration, where the circle portions (5) are adjacent and contained in a main plane of extension, to a closed rest configuration, where the circle portions (5) are at least partly superimposed so as to limit the volume in the main plane of extension, and vice versa. Owing to this particular arrangement it will be possible to increase the available space on-board the boat when the rudder is not used and, in so doing, facilitate the movements of the crew.

The invention concerns a quick connection and/or fastening system suited to mutually connect and disconnect a first and a second element, said system comprising a first and a second component that are suited to be rigidly fixed to said first and said second element, respectively, said first component and said second component being also suited to be mutually connected and disconnected in such a way as to alternatively allow said first and said second element to be mutually connected and disconnected, said second component being suited to house an end portion of said first component in such a way as to allow its translation inside said second component, said second component comprising also counteracting means suited to counteract the translation of said end portion of said first component towards the outside of said second component.

The invention is a device (1, 100, 200, 300, 400, 500, 600, 700) for converting a rotary motion into a linear motion, comprising a first threaded element (3) that defines a first axis (7), suited to be coupled with a second threaded element (4) defining a second axis (10), said axes (7, 10) being substantially parallel to each other but not coinciding with each other. The device (1) also comprises means (12) arranged between the first threaded element (3) and the second threaded element (4), suited to transmit the rotary motion imparted to one of the elements (3, 4) to the other.
