Saare Yachts - Vent Model 1

grabcad

Built with three-stages. Open, ajar and closed. User can operate it by pushing the button and twisting the handle with little angles. Has a smooth closing mechanism. Wings blocks the water to direct pass through inside even it is full opened. Rubber between wings and head provide waterproofness. So no air or water can enter when it is closed. Had some simulations for accidents. (Sumone can step on it accidently) So made the lead sheet of head made thicker and supported with mechanism body. Head material is important for kind of situations. I’ve used copper plated HSLA 400 steel sheet for head , wings, base and inside sheets. (head can be cast with gray cast iron and plated with copper.) Added rubber between wings and head. Mechanism body, arms ,elbows and lock catch can be cast with cast steel. Handle looks really nice with darkwood. (polished beech) And the button’s material doesn’t matter at all. Can be wood for nice look. --------- *revision: changed inside sheet, lock catch and indicator design. --------- **revision: added supports to head. had a new simulatiıon.
