A locking device particularly for snowboards which comprises a circular plate which is rigidly coupled to a board. The device is constituted by a rotating body which is rotatably associated with the plate and is provided with elements for engaging and temporarily compressing complementarily shaped grip elements associated with the sole of a shoe. There are also provided elements for temporarily locking the rotation of the rotating body.

Braking device, particularly usable for skates including a shoe composed of a quarter which is articulated to a shell which is in turn associated with a frame for supporting two or more wheels. A brake is rotatably associated with the quarter and selectively interacts with the ground upon a backward rotation of the quarter. The brake can oscillate in contrast with a spring and interacts with the ground upon a given rotation imparted to the quarter.

A transmission chain, particularly for a bicycle, has inner links alternated to outer links. The inner and outer links are constituted by pairs of plates articulated to each other by means of pins. The plates of the inner links have their outer surfaces with a depressed central portion. The plates of the outer links have their inner surfaces with a depressed central portion. The plates of the outer links further have through holes for engagement of the articulation pins with enlarged end mouths ...

A braking device, particularly for skates, including a shoe composed of a quarter that is articulated to a shell which is in turn associated with a frame to which two or more wheels are pivoted. The braking device is constituted by a substantially U-shaped elastic support that has V-shaped lateral wings; a brake pad is associated with the ends of the wings. The support also has a base that is pivoted transversely to the quarter.

A roof for vehicles, particularly convertibles: A roof material including an upper fabric layer, a lower fabric layer, a rubberizing layer arranged between the upper and lower fabric. Possibly a ceiling inner lining is arranged below the roof material. A protective layer is arranged on the lower fabric layer and/or on the top side of the ceiling inner lining. The protective layer consists of a cut resistant material of cut-proof fibers such as aromatic polyamide fibers, polyethylene fibers spun ...

A vehicle with mutually moving parts, such as doors and hinged lids or hinged covers, particularly with a foldable roof, has at least one front roof part and one rear roof part. These roof parts are provided with at least one joint connection, which makes an open and a closed position possible, and is constructed as a hinged device, which can be actuated directly from a controllable driving device.

In an umbrella, particularly a standing umbrella, sunshade, garden umbrella or similar, with a frame, a roof structure and a canopy, where the roof rods (5) are linked to a pole element (2) bearing a cap (3) and moveable in a telescopic manner relative to the vertical pipe (1), and a slide (4), on which stretchers (6) linked to the roof rods (5) act flexibly, is moveable along the vertical pipe (1), the cap (3) and the slide (4) moving in opposite directions during opening and closing of the umb...

Braking device, particularly usable for skates including a shoe composed of a quarter which is articulated to a shell which is in turn associated with a frame for supporting wheels. The device includes at least one cable which connects the quarter to a braking element, so as to allow to obtain the braking action when the quarter is tilted.

Cutting shears or pruning shears have one handle longer than the other handle. The tool can be used with two hands when cutting a cut-resistant object while maintaining the handiness and lightness of pruning shears for one hand.

At least one radiant heating resistor (10) formed from a corrugated flat material band has in different orientations projections (28) projecting from a corrugated longitudinal edge (14), which on the one hand for retaining purposes engage in an insulation (3) and on the other hand form longitudinal portions (39) with a slightly lower electrical resistance and which for the conventional operating power appear dark compared with the intermediate, visibly glowing longitudinal portions (38). Thus, o...
