Abstract

Abstract A rowing boat 10 has a fixed seat 14 and a movable foot stretcher 16 slidably mounted in guides 15. A swinging outrigger arm 17 is provided to support an oar by means of row lock 22 at its outer end. The inner end of outrigger 17 is pivotally mounted on a vertical axis 21. A coupling link 24 connects the stretcher to the outrigger 17, whereby as the stretcher is moved fore-and-aft during rowing the outrigger 17 is pivoted about axis 21. The link 24 is connected to the outrigger 17 at a point which is adjustable, and is always inboard of the rowlock. In an alternative embodiment the outrigger 17 is provided with a lifting member 33 which assists in raising the blade of the oar.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 156 words
An outrigger for supporting an oar comprising, a support, means for mounting the support on a boat to extend upwardly therefrom, an elongate link, means for pivotally connecting one end of the elongate link to the support such that the elongate link extends away therefrom, a carrier, means for pivotally mounting the carrier at the other end of the elongate link such that it depends therefrom, means for interconnecting the carrier at a point below said other end of the elongate link to the support at a point above the one end of the elongate link, the interconnecting means passing through the elongate link, and means for supporting an oar between the ends thereof on the carrier, the arrangement being such that when a force is applied to the oar in a sense to upwardly pivot the blade of the oar the apparent point of pivot lies between the carrier and the grip of the oar.
Claim 2
Dependent Claim 156 words
An outrigger for supporting an oar comprising, a support, means for mounting the support on a boat to extend upwardly therefrom, an elongate link, means for pivotally connecting one end of the elongate link to the support such that the elongate link extends away therefrom, a carrier, means for pivotally mounting the carrier at the other end of the elongate link such that it depends therefrom, means for interconnecting the carrier at a point below said other end of the elongate link to the support at a point above the one end of the elongate link, the interconnecting means passing through the elongate link, and means for supporting an oar between the ends thereof on the carrier, the arrangement being such that when a force is applied to the oar in a sense to upwardly pivot the blade of the oar the apparent point of pivot lies between the carrier and the grip of the oar.
Claim 3
Dependent Claim 112 words
A rowing rig for a boat, comprising a pair of upright arms at either side of the boat, the upper ends of the arms being mounted for pivotal movement about a common horizontal axis extending transversely of the boat, a stretcher extending between and carried by the lower ends of said arms, further arms upstanding from said stretcher, rowlocks carried by the upper ends of said further arms adjacent the gunwales of the boat, guide means for guiding the further arms for fore-and-aft movement, and link means pivotally interconnecting the further arms and the boat to maintain said further arms upright upon swinging movement of the stretcher about said common horizontal axis.
Claim 4
Dependent Claim 112 words
A rowing rig for a boat, comprising a pair of upright arms at either side of the boat, the upper ends of the arms being mounted for pivotal movement about a common horizontal axis extending transversely of the boat, a stretcher extending between and carried by the lower ends of said arms, further arms upstanding from said stretcher, rowlocks carried by the upper ends of said further arms adjacent the gunwales of the boat, guide means for guiding the further arms for fore-and-aft movement, and link means pivotally interconnecting the further arms and the boat to maintain said further arms upright upon swinging movement of the stretcher about said common horizontal axis.
