摘要:
The object of the invention is a pre-skiing exercise implement which enables to perform body and leg movements which are similar to those performed when turning (Christiania-like) to the right and to the left during a downhill run. This implement comprises two support bars (2) which are set in a parallel, side-by-side relation in the fashion of a pair of ski, and which are provided with means (3) for fastening to each one of them a ski-boot, either directly or through the respective ski (4). These support bars (2) have their rear end section slidably bearing on an inverted V-shaped supporting cross member (6), and at an intermediate position are supported by an articulated bar-supporting device (7), in which each one of the bars (2) can rock independently from the other bar, around an associated horizontal axis of inclination (X) which is transversal thereto, and both bars (2) can simultaneously perform concordant equal angular movements around associated upstanding axes of rotation (Y), which are vertical, or are preferably inclined rearwardly toward the inverted V rear supporting cross member (6).
摘要:
A mobile barrier (1) for temporary barrage of canals and harbour entrances essentially formed by a base (2) which extends on the bottom of the harbour entrance, and a series of sluice gates (3) of essentially rectangular shape which are hinged with one edge onto the base (2) one next to the other so as to swingingly turn about a main essentially horizontal axis of rotation (A); each sluice gate (3) being connected to the base (2) by means of a pair of disconnectable hinges (4) which consists in a fixed portion (4a) stably anchored to the base (2), and a mobile portion (4b) which is instead stably fixed to the sluice gate (3), incorporates the articulation joint of the hinge about the main axis of rotation (A) and is finally structured so as to couple with the fixed portion (4a) in a stable yet easily releasable manner.

A front impact damper (1) having a vertical supporting member (2) secured firmly to the ground, and a number of deformable tubular members (3) fitted vertically inside one another and fixed to the vertical supporting member (2) at a given height off the ground; the deformable tubular members (3) each being defined by a portion of W- or triple-groove-section corrugated sheet metal (4, 7) bent appropriately to form a cylindrical tubular body with a corrugated lateral wall.

A guardrail terminal (1) having a number of vertical supporting members (4) fixed into the ground one after the other along the edge (3) of the road; a curved or straight first transverse horizontal retaining member (5) fixed to the vertical supporting members (4) at a given height off the ground, and curving in the horizontal plane so as to extend gradually away from the edge (3) of the road, as of the end of the guardrail (2); and a curled second transverse horizontal retaining member (6), which projects from the terminal end (5a) of the first transverse horizontal retaining member (5), curves back in the horizontal plane towards the first transverse horizontal retaining member (5), and is fixed by its own terminal end (6a) to the start end (5a) or to an intermediate portion of the first transverse horizontal retaining member (5), so as to form, together with the first transverse horizontal retaining member, a substantially tear-shaped collapsible annular member (7).
摘要:
A soundproofing panel (1) for acoustic barriers, which is defined exclusively by a sheet (2) preferably, though not exclusively, made of metal, and having, on one of the two lateral surfaces, a number of longitudinal sound-breaking fins (3) parallel to and facing one another, and each for breaking the front (F) of the incident sound wave; the longitudinal sound-breaking fins (3) having a T-shaped section, and being equally spaced along the whole lateral surface (2a) of the sheet (2) to define a number of open gaps (4) for preventing propagation of the incident sound wave; each gap (4) possibly housing an insert (9) of soundproofing and/or sound-absorbing material; and the back of each gap (4) possibly having drawings (11) with the concavity selectively facing inwards or outwards of the gap (4) to vary the total volume of each gap (4) on the soundproofing panel (1) as required.
摘要:
A cross member (1) for "LAYHER" type fast-fit prefabricated scaffolding or similar, having a tubular member (6) of predetermined length and two end attachments (7) located at the two ends of the tubular member (6) and designed to fit onto the anchoring plates (4) of the vertical members (2) of the "LAYHER" type fast-fit prefabricated scaffolding or similar; the two end attachments (7) being formed in one piece with the tubular member (6) by mechanical working, to permanently deform the wall of the tubular member (6), and by subsequent cold cutting.

摘要:
An acoustic insulating panel (1) made of composite material and having a shell (8) in turn having a number of longitudinal reinforcing ribs (10, 13) and at least one layer (16, 17) of sound-absorbing material housed between two adjacent ribs (10, 13); the shell (8) being formed by bending thin sheet material; the layer (16, 17) of sound-absorbing material being sprayed or poured on, or applied by mechanically fastening and/or chemically bonding preformed elements; and the sound-absorbing material being replaced by or integrated with a further layer (18) of vibration-damping material.
