Abstract: A device apt to guarantee the stable blocking of a rotary or sliding door with respect to a fixed surface or frame, of the type consisting of a male element and of a female element, the latter being shaped so as to house said male element and retain it in an easy detachable way. According to the invention, said female element comprises a pair of mutually spaced-apart, parallel, elastic wings, projecting from a support base, and said male element consists of a substantially spherical knob, having a diameter slightly larger than the distance between said elastic wings, apt to snap engage between said elastic wings. Moreover, with said base of the female element and/or with said knob of the male element there are associate position adjustment means, for example in the shape of a square wing, and facilitated fastening means, for example in the shape of a single fastening screw.

Abstract: A panel support clamp consisting of: at least a pair of mutually cooperating jaws (1,2) and both carrying, on one side, fastening and tightening elements; said fastening and tightening elements providing, on a first one of said jaws, a parallelepiped body (6) with at least one screw-in seat and, on a second one of said jaws, a tightening screw, as well as guiding elements for the housing of said parallelepiped body, consisting of a pair of retaining arms (9a, 9b) and of a cavity obtained on the inner surface thereof; on each of the lateral walls of said parallelepiped body a guiding groove (13), for the housing and sliding of a pair of articulating pins (14a, 14b), protruding inwards from the ends of said retaining arms; within said parallelepiped body recesses (7) for the introduction of fastening elements to a support base, and control means maintaining secure the parallelism between the opposite surfaces of the two jaws (1,2) and the respective panel walls.

Abstract: The invention concerns a vent cap for oil tanks of machines and motor equipment, comprising a cup (1), equipped with means of engagement (4) with the seat of the tank filler, and a lid (12) mounted on the cup and which snaps thereon. Between the cup (1) and the lid (12) there is a gap allowing the vapor outflow from the tank to the outer environment or viceversa. According to the invention, said lid (12) comprises two cylindrical diaphragms (12b, 12c), concentric to the cap axis and which, in cooperation with the cup (1), form labyrinth means for the flow of vapors and air. Cup (1) also carries a guide (7) supporting a level rod (8), consisting of a central, cylindrical main body (7b), wherefrom ribs (7a) for anchoring to the cup (1) depart. Guide (7) extends, at the top, into two flexible flaps (7c), provided with means of engagement (10) of the rod (8).

Abstract: A safety grip for a handwheel which is movable between an operating position and a home position is comprised of an elongated and ergonomic body (1) and of a support (2), which is anchored to the body of a maneuvering member, such as a handwheel. The body (1) is comprised of an outer case (1a), a rod-like inner core (3) with a head (4), a bushing (6) slidably mounted on the core (3), a sleeve (7) in sliding engagement on the bushing (6), an axial thrust spring (9) arranged between two opposite shoulders (6a) and (7a) of the bushing (6) and of the sleeve (7), and a second thrust spring (10) arranged between the head (4) and the top of the bushing (6). The body (1) is connected to the support (2) at a pivot point (5). An end of the sleeve (7) engages a contact surface of the support (2) through a collar (8). The collar (8) has an inner conical mouth surface that engages a shaped rib (11) on the top of said support (2), where the shaped rib (11) has a frusto-conical outer surface.

Abstract: The invention concerns a hinge of the type consisting of two flap-shaped main components (1, 2), having a mutual-engagement area (3) on a common pivoting axis. The hinge provides that with one of the flaps (1, 2) there is integral a head (4) of the pivoting axis, having a cam-shaped profile, and that with the other flap (1, 2) there is associated a switch body (5) wherefrom a control pin (9) protrudes. An outer end of the control pin (9) engages with said cam-shaped profile, and an end inside the body (5) acts on a button (11) actuating a switch (10) arranged within said body (5).

Abstract: A device for closing, connecting and/or locking including a driving element and a driven element having a threaded end. The driven element is at least partially positioned within the driving element. An axial anchoring structure axially anchors the driving element to the driven element while allowing rotation of the driving element and the driven element. A rotational anchoring structure anchors the driving element to the driven element for unitary rotation in a first rotation direction, only up to a limited tightening torque. The rotational anchoring structure allows the free rotation of the driving element in a second rotation direction opposite to the first rotation direction. A locking structure locks the driving element with driven element for unitary rotation in the second rotation direction.

Abstract: A handwheel (1) for stable, reversible engagement with an engagement end (Q) of a shaft (A) of a member to be operated. The handwheel (1) includes a stem (2) having a free end, a cavity (2A) provided in the stem (2) for cooperating with the end (Q) of the shaft (A), an elastic ring (5), and a retaining washer (6). The cavity (2A) has an open end proximate the free end of the stem (2). A first seat (3) accommodates the elastic ring (5). The first seat (3) is located proximate to the open end of the cavity (2A). A second seat (4) accommodates the retaining washer (6). The second seat (4) is located proximate to the open end of the cavity (2A).
