Title:
ROWLOCK WITH ADJUSTABLE INCLINATION
Document Type and Number:
WIPO Patent Application WO/2014/170884
Kind Code:
A3
Abstract:
A rowlock (20) comprising: a rotatable portion having a support surface (22) for an oar (2) and arranged to rotate about a pivot (4) having a first fixed rotation axis (19); an inclination adjustment means (25) for adjusting an inclination angle (a) with respect to the first rotation axis (19); a manoeuvre element (24) for enabling an operator to rotate an engagement portion (21 ) about a second rotation axis (18) that is substantially orthogonal to the first rotation axis (19), in order to bring the inclination adjustment means (25) from a first inclination (Oi) to a second inclination (a2) of the support surface with respect to the first rotation axis (19); a blocking means of said inclination- adjustment means, configured to keep the inclination at a prefixed angle (a) while rowing. The main feature of the rowlock (20) is that it comprises a connection portion (23) for rotatably mounting to a watercraft the engagement portion (21 ), which is configured to rotate about the first rotation axis (19) and to rotate with respect to the connection portion (23) about the second rotation axis (18), where the manoeuvre element (24,41, 41 ',41 ") is arranged for causing the engagement portion to rotate (21 ) about the connection portion (23) about the second rotation axis (18); and where the manoeuvre element (24,41,41 ',41 ") is arranged on the engagement portion (21 ). This way, the inclination angle between the rotation axis and a direction normal to the support surface of the engagement portion of the rowlock (20) can be changed easily and quickly, in particular on board of the watercraft, enabling a rower to easily set the inclination at a customized angle, improving rowing efficiency, without keeping spare parts on board to change the inclination angle between the rotation axis and a direction normal to the support surface of the engagement portion of the rowlock.
