摘要:
A swimming fin comprising a blade extending from a shoe open at its rear side, and a rear heel strap connected to the sides of the shoe by at least one buckle, the buckle having a base plate integral with the shoe. A buckle arm is joined with the strap so as to allow adjustment of the strap's tension, an intermediate lever being connected pivotally to the base plate and the arm. A reversible attachment member is also provided for connecting the intermediate lever to the base plate to achieve closure of the buckle. Between the intermediate lever and the base plate, a disengageable articulation member is provided for reciprocal engagement between them, a pivotal connection, and, at the same time, for allowing their separation in a direction opposite to that of tensioning the strap. In this manner, the intermediate lever may be separated from the base plate following release of the attachment member, and disconnection of the disengageable articulation member.

A device for releasably connecting a weight pouch to a pocket of a scuba diving jacket. The device comprises: a flat sheath integrally connected to the scuba diving jacket; a latch member being attached to the weight pouch and having arms that are elastically deformable in the plane of the sheath and have sides tapered relative to the longitudinal plane of symmetry of the sheath to produce a snap closure when the latch member is inserted in the sheath. An inward-projecting abutment inside the sheath engages the ends of the arms when the device is closed, thereby preventing the latch member from sliding out of the sheath. A member is provided for bending the arms of the latch member so as to release them from the position where they abut the abutment in the sheath and enable the device to be opened. The bending member comprises a cap slidingly mounted on the latch member and containing tapered projections for engaging the tapered sides of the arms in order to release the ends of the arms from the abutment in the sheath as a result of relative movement of the cap in relation to the latch member that induces elastic deformation of the arms. The cap and the latch member are preferably connected to the same handle for inducing their relative movement by respective flexible connection elements, of which the one connecting the handle to the latch member is longer than the one connecting the handle to the cap, whereby a tensile force exerted on the handle first causes relative movement of the cap with respect to the latch member inside the sheath

A device for regulating the length of the strap (3) on a scuba diving mask, the mask comprising a frame (1) for supporting one or two lenses and two fork-shaped portions (1a) extending from either side of said frame, each containing a pivot (15) around which a portion of the end (3a) of the strap is wrapped, said portion of strap being formed with a plurality of transverse stop ribs (4) on one side. The regulating device comprises a stop lever (16) housed inside each of the fork-shaped portions (1a) and a tooth (8) extending from the lever for engaging with one of the ribs. The lever comprises a substantially U-shaped member (6) and a tongue (7) extending from the base (6a) of the U-shaped member so that it is coplanar and cantilevered inside it, the tooth (8) extending transversely from the tongue (7). On the side opposite the tooth, a head (10) extends from the tongue, against which a wedge-shaped portion (26) of a button (25) abuts, sliding with respect to the fork-shaped portion on a plane parallel to the U-shaped member, whereby, when the button is pressed, the head is caused to slide away from the U-shaped member, with a consequent lifting of the tongue and the disengagement of the tooth from the stop rib (4).

摘要:
A scuba diving mask with corrective lenses comprising a frame with a pair of rings connected by a bridge, each of the rings having an internal flange on which the lip of a flexible skirt, a corresponding lens and a lens-retaining collar rest. The collar is attached with a snap action to the corresponding ring. A seat is formed in the bridge substantially in the lying plane of the lenses and extending laterally to the upper internal portion of the two rings. The seat contains a locking plate slidable between two opposite end stroke positions, a locking end position and a release end position respectively, when the locking plate is in the locking position the lateral sides of the locking plate extend inside the rings and are engaged in corresponding notches provided in the upper internal rim of the lens-retaining collars.

A swimming fin comprising a blade extending from a shoe open at its rear side and with a rear heel strap connected at the sides of the shoe by at least one buckle, said buckle comprising a base plate integral with the shoe, a buckle arm connected to the strap so as to allow adjustment of its tension and an intermediate lever connected pivotally to the base plate and to the arm, reversible attachment means also being provided for connecting the intermediate lever to the base plate to achieve closure of the buckle. Between the intermediate lever and the base plate disengageable articulation means are provided, for achieving reciprocal engaging between them and a pivotal connection and, at the same time, allowing their separation in the direction opposite to that of tensioning of the strap. In this way, the intermediate lever can be separated from the base plate following release of the attachment means and disconnection of the disengageable articulation means.
