Abstract
A boat hull support has a pair of support members each pivotally attached to a respective upright. The inner ends of the support members oppose each other. One of the inner ends mounts a pair of cam plates having aligned banana-shaped cam openings. The other inner end mounts a follower rod received in the cam openings. The cam openings are shaped so that movement of one of the support members about its pivot will be translated into an equal and opposite movement of the other. The support members are urged to a generally horizontal position by leaf springs or elastomer blocks bearing against the underside of the support members.
Claims11
A boat hull support, comprising:
- a pair of hull support members each pivotally mounted intermediate its ends to a respective upright and having adjacent inner ends;
- a cam attached to the inner end of one of the hull support members;
- and
- a cam follower attached to the inner end of the other hull support member and engaging the cam,
- the cam having a cam surface developed to translate movement of one hull support member about its respective upright resulting from a load on the one hull support member into equal and opposite movement of the other hull support member about its respective upright.
A boat hull support comprising:
- a pair of hull support members each pivotally mounted intermediate its ends to a respective upright and having adjacent inner ends;
- means joining the inner ends of the hull support members to translate displacement of one of the support members on its pivotal mounting into an equal displacement of the other support member on its pivotal mounting;
- and
- a spring urging the support members to a generally horizontal position.
