Abstract
A mast collar system for securement to a surface at the location where the mast extends down through the surface includes a rigid collar which loosely encircles the mast. Positioned in the gap between the mast and the collar is a resilient ring. An annular groove extends down into the ring and a spline is pressed down into the groove so that a fluid-tight gasket is formed between the mast and the collar. The ring or spline also includes a fin which resiliently engages the mast directly above the annular line of sealing engagement between the mast and the ring per se.
Claims19
A mast collar system comprising
- A. a rigid collar for loosely encircling a mast at the location where the mast projects through an opening in a boat deck or other surface, a portion of the collar being arranged to engage and be secured to the boat deck outboard of the opening therein,
- B. a flexible resilient ring for engaging around the mast, said ring having an annular portion arranged and adapted to be positioned in the annular gap between the mast and the collar encircling the mast to provide a resilient gasket between the mast and the collar,
- C. means defining an annular groove in the top of the ring, said groove extending down into the ring, and
- D. a spline arranged to be pressed down into said groove so as to compress the ring portion positioned between the mast and the collar.

- A. a rigid collar for loosely encircling a mast at the location where the mast projects through an opening in a boat deck or other surface, a portion of the collar being arranged to engage and be secured to the deck or other surface,
- B. flexible resilient means arranged and adapted to be positioned in the gap between the mast and collar to function as a fluid-tight gasket,
- C. journal means distributed around the collar, and wherein
- D. said collar is formed with spaced-apart upper and lower lateral flanges,
- E. said journal means comprises pairs of aligned openings in said collar flanges, and
- F. said securing means comprises a pin extending through a pair of said openings and through said portions of the block positioned between said collar flanges, and
- G. further including at least one block swivally secured to said pin.
