47060700, Nov 10, 1987

Filed:

Aug 4, 1986

Appl. No.:

6/892274

Inventors:

Steven A. Forti - Norwell MA
Robert F. McNulty - Brewster MA

Assignee:

Eclipse Technologies - Norwell MA

International Classification:

G08B 2100
G08B 1314

US Classification:

340568

Abstract:

A self-contained alarm system mounted in a housing is adapted to be mounted between the clamps of an outboard motor and the transom of a boat. The clamps of the outboard motor are electrically coupled to circuit means in the housing of the alarm system through electrically conductive sensor members in the housing. The circuit means acts as a discontinuity or open circuit detector. When a clamp of the outboard motor is backed off, either intentionally or accidentally, the circuit means electrically detects the change of resistance and activates a sound device located in the housing.

Abstract:

A self-contained alarm system for a boat outboard motor connected to a boat transom by clamps is easily retrofit onto an existing boat. A housing of tough non-conductive material (such as polycarbonate) contains a power source (such as a battery) and a signalling device (such as a horn or lights). The housing includes a hub and a pair of arms, which are pivotal with respect to each other about the hub, or the arms can be sliding members, sliding relative to each other. Electrical contacts are provided adjacent the end of one or both of the arms, the contacts engaging clamp pads. If the clamp pads are moved out of operative engagement with the contacts, the battery activates the signal device. A circuit for sensing an open circuit condition may interconnect the signal and battery may be provided, or the contacts may be designed so that a closed circuit actuates the signal.
