Abstract
Abstract A quick release-hook to be secured to the chest harness of the rider of a board sailer. The hook helps in bracing the sail of the board sailer by engaging a loop of a rope attached to the boom-like rail of the board sailer. The hook (9) pivots from hooking to release position when the rider moves the rope through the hook so that thicker portions of the rope can press abutment members (21), forcing resilient tongue (17) out of engagement with the hook which then pivots, passing through slot (25) between members (21) to release the rope.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
249 words
A quick-release apparatus for attaching a rider to a board sailer comprising: a base member; a support member extending outwardly from said base member; a hooking member pivotally supported on said support member for rotation in a plane perpendicular to said base member; said hooking member comprising a latching end portion extending toward said base member and a curved hook portion extending away from and curved back toward said base member; a trigger member comprising a tongue fixed to said base member beneath said hooking member and having one end resiliantly biased outwardly to engage said latching end portion; an abutment member mounted on said trigger member tongue and extending into said hook portion of said hooking member to form a spaced area therebetween; and a flexible rope means having a center portion of a diameter smaller than said spaced area and end portions of a diameter larger than said spaced area, said center portion being adapted to engage said hook portion of said hooking member and be laterally slidable between said hooking member and said abutment member, whereby lateral movement of said rope means within said spaced area to a postion where said larger diameter end portion comes between said hook portion and said abutment member will cause said trigger member to be urged toward said base member, thereby disengaging said trigger member from said latching portion and permitting said hook portion of said hooking member to pivot away from said base member and disengage said rope means.
Claim 2
Dependent Claim
249 words
A quick-release apparatus for attaching a rider to a board sailer comprising: a base member; a support member extending outwardly from said base member; a hooking member pivotally supported on said support member for rotation in a plane perpendicular to said base member; said hooking member comprising a latching end portion extending toward said base member and a curved hook portion extending away from and curved back toward said base member; a trigger member comprising a tongue fixed to said base member beneath said hooking member and having one end resiliantly biased outwardly to engage said latching end portion; an abutment member mounted on said trigger member tongue and extending into said hook portion of said hooking member to form a spaced area therebetween; and a flexible rope means having a center portion of a diameter smaller than said spaced area and end portions of a diameter larger than said spaced area, said center portion being adapted to engage said hook portion of said hooking member and be laterally slidable between said hooking member and said abutment member, whereby lateral movement of said rope means within said spaced area to a postion where said larger diameter end portion comes between said hook portion and said abutment member will cause said trigger member to be urged toward said base member, thereby disengaging said trigger member from said latching portion and permitting said hook portion of said hooking member to pivot away from said base member and disengage said rope means.
